Using recent advances in science mapping, this article systematically reviews the Human Resource Management (HRM) field. We analyze 12,157 HRM research articles published over
23 years to reveal the topic content and intellectual structure of HRM scholarship. A downloadable, searchable HRM topic map is provided (http://bit.ly/HR-Map) that reveals: a) 1702 HRM
article topics, b) the number of articles on each topic, c) topic relations, trends, and impact, and
d) five major HRM topic clusters. We discuss the overall intellectual structure of HRM scholarship and review the five topic clusters. Next, the topic content of HRM scholarship is compared
to that of 6114 articles from the practitioner-oriented outlet HR Magazine. We identify 100
topics emphasized to a much greater degree in the practitioner-oriented literature. Seven key
themes for future research that could help align HRM scholarship with the interests of HR practitioners are identified and discussed.

1. Introduction
In the Human Resource Management (HRM) field, review articles typically consider only some of the “trees”, but lack the
scope to provide a synthetic overview of the “forest” of HRM scholarship. In particular, HRM review articles typically focus on examining the contents of a small number of articles on a specific topic or research question. As such, scholars are likely to have a
fragmented and incomplete view of the field overall, which may result in research silos, redundant research efforts, and lost opportunities for meaningful conversations between topic areas. Moreover, narrow, disconnected, and incomplete views of the HRM
field can limit scholars' ability to detect research opportunities.
In recent years, new alternatives to the traditional narrow review have emerged. In particular, what can be called structural
reviews 1) examine the relations between topic areas, and 2) use some form of quantification to succinctly summarize a large literature (Porter, Kongthon, & Lu, 2002). As Porter et al. (2002), a broad scan of a literature “can extend the span of science by better linking efforts across research domains. Topical relationships, research trends, and complementary capabilities can be
discovered, thereby facilitating research projects” (p. 351). In addition, because structural reviews employ some form of quantification and objective analysis, such reviews “improve the review process by synthesizing research in a systematic, transparent, and
reproducible manner” (Tranfield, Denyer, & Smart, 2003, p. 207). In doing so, structural reviews help overcome a key limitation of
traditional review articles: their lack of rigor (i.e. biased, subjective, impressionistic description).

M.P. Markoulli et al. / Human Resource Management Review 27 (2017) 367–396
In this article, we employ science mapping from the discipline of bibliometrics to provide the most comprehensive and systematic review of the HRM field to date. In particular, while a traditional review might analyze 50–200 articles, this review is
based on a rigorous analysis of 12,157 systematically identified HRM research articles published over N23 years. The science
map analysis on which this review is based is presented to readers in the form of the downloadable HRM Map, which allows
readers to explore: a) 1702 topics in HRM scholarship, b) the number of articles on each topic, c) topic relations, trends, and impact, and d) five systematically identified, major HRM topic clusters. After presenting this analysis, we describe how scholars can
use the downloadable HRM Map and systematic reviews provided to identify promising future research opportunities from across
the HRM literature using the process of abductive reasoning.
In the latter portion of this article, we turn our attention to identifying research opportunities that can help bridge the “research-practice gap” in HRM. In particular, a number of HRM scholars have raised concerns that there may be discrepancies between the topics studied in HRM scholarship and the topics of interest to HR practitioners (e.g. Deadrick & Gibson, 2007, 2009;
Rynes, Giluk, & Brown, 2007). However, prior attempts to identify if/where these gaps exist have drawn on limited samples of
HRM scholarship, and employ methods that only identify discrepancies at the level of broad topic categories (e.g. Strategic
HRM) (e.g. Deadrick & Gibson, 2007, 2009). As such, it is difficult to know a) whether the discrepancies identified previously
are artifacts of the limited sample of HRM scholarship analyzed, and b) which specific topics warrant greater scholarly attention.
The second major section of this paper aims to address these issues by providing a comparative topic analysis of 1) the 12,157
HRM research articles versus 2) 6114 articles from a key practitioner-oriented outlet: the Society for Human Resource Management's HR Magazine. We systematically identify 100 specific topics with the greatest discrepancy in emphasis between HR
practitioner-oriented writing versus academic HRM. We then review seven topic themes for future research that could help
align HRM scholarship with the interests of practitioners.
This article endeavors to make four substantial contributions to HRM scholarship. First, we aim to provide the most rigorous
description of the intellectual structure of HRM field to date – offering readers a bibliometrically grounded taxonomy of HRM literatures, a searchable topic map of the field, reviews of five systematically identified major topic literatures in HRM, and views of
changes in the field over time. Second, we describe how opportunities for future scholarship can be detected by applying
abductive reasoning to the downloadable HRM Map and topic cluster reviews. Third, the identification of 100 specific topics emphasized to a much greater degree in practitioner-oriented (as compared to academic) HRM provides actionable insights as to
which topics HRM scholars could attend to to help address the “research-practice gap”. Fourth, we conclude with a number of
provocations meant to evoke “big picture” reflection by HRM scholars on the status and trajectories of their literatures, and to
flag what we see as key challenges and opportunities for these literatures going forward.
2. Prior reviews of the HRM field and the added value of science mapping
Existing reviews on the HRM field can be categorized as either: 1) narrative reviews, or 2) structural reviews. Traditional narrative reviews tend to be impressionistic, offer a paper-by-paper analysis, and consider a fairly narrow topic area (e.g. green HRM
- Renwick, Redman, & Maguire, 2013; e-HRM - Stone & Dulebohn, 2013). As can be seen from Table 1, the majority of narrative
reviews in the HRM literature – i.e. 94 out of 115 articles – offer in-depth consideration of a particular HRM topic area. While
valuable, these narrow reviews profile the “trees”, but not the “forest”.
At a macro level, 19 narrative field-level reviews have attempted to provide a broad description of the HRM field (see Table 2)
from methodological (e.g. Guest, 2001; Williams & O'Boyle, 2008), historical (e.g. Kaufman, 2014), and theoretical (e.g. Ferris,
Hochwarter, Buckley, Harrell-Cook, & Frink, 1999) standpoints. However, as such narrative reviews are impressionistic (rather
than systematic) in their analysis, the validity of their descriptions and conclusions are questionable (Tranfield et al., 2003). Indeed, many of the questions considered in narrative field-level reviews of HRM (e.g. What are the field's major topic areas?
What are the topics that have received the most research attention? How well integrated are various literatures within the
field?) are ultimately empirical questions that can be answered through quantitative analysis of scholarship.
In contrast with narrative reviews, what we label as “structural reviews” take a different approach. Structural reviews have a
macro focus and use some form of quantification to consider patterns across multiple topic literatures (Porter et al., 2002). Five
structural reviews have attempted to profile the HRM field overall in various ways, and identify its subfields (Deadrick &
Gibson, 2007, 2009; Fernandez-Alles & Ramos-Rodriguez, 2009; García-Lillo, Úbeda-García, & Marco-Lajara, 2016; Hoobler & Johnson, 2004). These articles are a substantial improvement over assertions about the major categories of HRM scholarship that are
not grounded in any quantitative analysis of scholarship (e.g. Martín-Alcázar, Romero-Fernández, & Sánchez-Gardey, 2008). While
these prior works make important contributions, they also all have major limitations.
First, prior structural reviews of the HRM field have tended to rely on intuition to determine the major categories of HRM
scholarship, and rely on subjective assessments to assign topics and articles to these categories. While authors' intuitively derived
categories of HRM scholarship can be informative, they can also inadvertently introduce author bias and mischaracterizations into
the picture of the field they present (Tranfield et al., 2003). For example, new topic areas or those that authors are unfamiliar with
can be overlooked. Indeed, given the size of the HRM literature, intuitively derived topic categories are unlikely to fully and accurately represent the field's topic content and structure. In contrast, new bibliometric approaches can be used to systematically
identify 1) scholarly topics, 2) higher-level topic domains, and 3) which topics empirically “belong” to which topic domains.
Second, the few articles that attempt to empirically identify major HRM topic areas rely on article samples from one or two
journals that represent only a fraction of the HRM literature (Deadrick & Gibson, 2007, 2009; Fernandez-Alles & RamosRodriguez, 2009; García-Lillo et al., 2016; Hoobler & Johnson, 2004). Drawing on non-representative samples can misrepresent

(Journal of Applied Psychology, Personnel Psychology), Deadrick and Gibson's (2007, 2009) research designates Teams/Work groups

narrow sample leads the authors to find that Teams/Work groups is a larger HRM research literature than International HRM. The
authors acknowledge that drawing on two journals is a limitation, further noting that “Admittedly these two journals are outlets

that focus on the interests of Industrial/Organizational (I/O) Psychologists” (Deadrick & Gibson, 2007, p. 137). Similarly, GarcíaLillo et al. (2016, p. 1486) also note the “selection of a single journal: IJHRM” as a limitation of their study. Without an actual
field-level assessment that systematically identifies HRM scholarship from across journals, it is difficult to know how representative any one HRM journal is and/or if particular journals skew toward particular kinds of HRM scholarship. Indeed, our use of
bibliometrics to identify a more comprehensive body of HRM scholarship suggests the need for caveats around the claims
made in the above mentioned studies, as their source journals appear to skew toward certain kinds of HRM scholarship in
ways that are likely to overlook at least one (and as many as three) major HRM literatures. Thus, the representativeness of
these prior depictions of the HRM field is questionable.
In contrast, the field of bibliometrics has developed methods for rigorously identifying and analyzing large academic literatures
to produce dramatically more complete pictures of scholarly fields. These approaches are becoming increasingly popular in Management and across the sciences (Zupic & Čater, 2014), but have yet to be used to analyze an inclusive sample of HRM
scholarship.
3. HRM Map methodology
To provide a systematic review of the HRM literature, we employ the VOSviewer science mapping framework (van Eck &
Waltman, 2010, 2014). VOSviewer facilitates three considerable improvements over prior attempts to review the HRM field,
namely 1) a significant increase in the amount of scholarship that can be analyzed, providing a more representative basis for
reviewing the field, 2) a rigorous set of bibliometric methods designed to systematically identify the intellectual content and
structure of the field, and 3) an improved level of detail in the representation of the field's topic content. By using VOSviewer science mapping, we are able to provide readers with a downloadable and dynamically explorable topic map of the HRM field that
can be used to examine the intellectual content and structure of HRM in rich detail. These advantages are likely reasons why
VOSviewer has become a popular tool for analyzing and reviewing scholarship, and has been widely employed to profile numerous literatures across the sciences in the past few years (VOSviewer - Publications, 2015).
3.1. Sample
A four-stage process was used to identify HRM scholarship for analysis. First, we searched the Web of Science (WoS) for articles from 132 management journals1 published between January 19922 and August 2015, which contained at least one of the
following search terms in their title or abstract: HR, SHRM, HRM, human resource (including any suffix), and personnel manage
(including any suffix). This initial search identified 7887 articles. Second, we identified any additional articles published in “niche
HRM journals” (i.e. journals with a principle focus on HRM). Journals were considered to be niche journals if at least 40% of the
articles they published since 1992 included one or more of the search terms mentioned above. Six journals met the criteria: Asia
Pacific Journal of Human Resources, Human Resource Management, Human Resource Management Journal, Human Resource Management Review, International Journal of Human Resource Management, and Personnel Review. Third, we conducted a manual review of
journals with a slightly lower inclusion percentage and identified two additional niche HRM journals: International Journal of Manpower and International Journal of Selection and Assessment. 1674 additional articles were collected. Fourth, we then collected and
manually reviewed all articles not yet included in our corpus with at least one reference to any of the selected niche journal articles. This step identified 2596 relevant articles, leading to a total of 12,157 HRM articles identified from the WoS database.
3.2. Analysis
The HRM Map was created by using the VOSviewer framework of science mapping methods to analyze the primary topic content of article titles and abstracts. To prepare titles and abstracts for analysis, we merged abbreviations and their full terms (e.g.
chief executive officer and ceo) into the most common form of the term in the article dataset (e.g. ceo), and very long terms into
more abbreviated forms (e.g. “strategic human resource management” into “strategic HRM”). We further standardized terms by
converting British spellings to U.S. English.
Once titles and abstracts were prepared for analysis, we used the VOSviewer term identification function to systematically
identify the key topics of articles. The key article topics in academic writing are typically in the form of noun phrases (i.e.
nouns plus any preceding nouns or adjectives) in article titles/abstracts (Justeson & Katz, 1995). Thus, VOSviewer uses natural language processing to identify noun phrases in the titles/abstracts of scholarly articles. Next, a term occurrence threshold is applied,
such that a term needs to occur in the title/abstract of at least 10 different articles to be considered as a candidate term for mapping. The threshold of 10 occurrences helps ensure reliable placement of term relations in the map, and has been shown to help
remove misspelled and non-meaningful noun-phrases (see van Eck, 2011). Thus, the 10 article occurrence threshold is the default
in VOSviewer.
Once noun phrases were identified and standardized, terms were independently coded by two authors based on a classification scheme inspired by Lee, Felps, and Baruch (2014) and Whetten (1989). In particular, terms were coded into five categories:
1
These are the management journals identified by Felps, van Eck, Waltman, and Meuer (2014) with reference to the 36th edition of Anne-Wil Harzing's Journal Quality List, extended with ten HRM related journals.
2
The WoS does not systematically contain articles published before 1992 (Thomson Reuters, 2016).
372
M.P. Markoulli et al. / Human Resource Management Review 27 (2017) 367–396
“how-terms” (i.e. research design, statistical techniques; e.g. “cluster analysis”), “who-terms” (i.e. individual and collective actors;
e.g. “expatriate”, “top management team”), “what-terms” (i.e. concepts, variables, theories; e.g. “human capital”), and “whereterms” (i.e. industries, work contexts, geographic areas; e.g. “hospitality industry”, “China”). Terms that did not fall into these categories were excluded (e.g. “Elsevier”, “John Wiley & Sons”, “summary”, “significant finding”). Inter-rater reliability between the
two raters' codes was high (Cohen's Kappa = 0.89). The HRM Map contains 1702 terms.
To prepare terms for mapping, VOSviewer measures the relatedness of terms using the association strength measure. In particular, the degree of relatedness between terms on the map is determined by the ratio of co-occurrence between two terms over
the product of the occurrence counts of the two terms (Rip & Courtial, 1984; van Eck & Waltman, 2009). In other words, association strength is the observed co-occurrence between the two terms as compared to the degree to which each term co-occurs
with other terms in the article sample.
Next, VOSviewer visualizes term relatedness in a downloadable, two-dimensional map. The placement of terms on the map is
determined by the VOS mapping algorithm, which minimizes the difference between association strength and distance between
term pairs such that, on average, terms that tend to co-occur in article title/abstracts are placed closer together (van Eck &
Waltman, 2011). We used 250 random starts in order to help increase the likelihood of a robust mapping solution.
Finally, the VOS clustering algorithm is applied, which uses an optimization algorithm to systematically identify categorical
clusters of terms (i.e. topic areas) based on their patterns of relatedness. The clustering algorithm maximizes the sum of the association strengths of pairs of objects belonging to the same cluster while minimizing the size of the clusters (Waltman & van Eck,
2013). To identify clusters, we used the default VOSviewer clustering resolution parameter of 1 and set a minimum cluster size of
50 terms (i.e. enough terms to review and be viewable in a static map image). Like the mapping algorithm, 250 random starts
were used to arrive at the final clustering solution. The VOSviewer clustering algorithm identified five term clusters.
3.3. Limitations
The set of HRM articles identified for this sample may differ from those one might identify using other sampling strategies. For
example, an alternative sampling strategy would have been to manually review all articles in all management journals and identify the ones that met a particular definition of Human Resource Management. Although this manual process would also have significant limitations (e.g. introducing considerable subjectivity into the article selection process, time intensiveness), such a process
could capture HRM articles that did not meet any of our article search parameters (i.e. not published in an HRM-niche journal, nor
contains any of our search terms in its abstract/title, nor cites any HRM niche journal at least once). However, we believe that the
systematic criteria we applied are reasonable for identifying HRM scholarship. Indeed, the sample of 12,157 HRM articles we identified through systematic application of the criteria above appears to be the most rigorous and comprehensive effort to identify
HRM scholarship to date.
3.4. Results
3.4.1. Map downloading and navigation, fundamentals of interpretation, and HRM Map views
The scientometric analysis described above is visualized in the form of the searchable HRM Map, which will download to your
computer when you click the link: http://bit.ly/HR-Map.3 Once the HRM Map is downloaded and opened, viewers can use their
mouse (or the buttons in the top right corner) to zoom in on particular areas in the map. Specific topics can be found by
using the search bar located on the “Items” tab on the left hand side of the map viewing window. The size of a particular topic
on the map indicates the number of articles on that topic, and the exact number of articles associated with each topic appears
when the viewer hovers their mouse over a topic node in the downloaded map. The distance between topics indicates their degree of co-occurrence in articles in the sample, where topics that tend to co-occur are positioned closer to one another.
The HRM Map has four different map views which each provide different information. First, the “Network visualization” of the
map indicates the five systematically identified clusters of related topics (i.e. topic areas) by the color of the topic nodes (see static
screenshot in Fig. 1).
A second way of viewing the HRM Map can be seen by clicking the “density visualization” tab above the map image (see static
screenshot of the density visualization in Fig. 2). In the density visualization, colors ranging from green to red in intensity indicate
the number of articles associated with the topics within a given space on the map. In particular, red indicates areas of comparatively high research intensity, while green indicates topic areas with comparatively less research intensity.
A third way of viewing the map can be seen by clicking the “Overlay Visualization” tab above the map image (see Fig. 3). This
view shows which topics are “trending” and “cooling off”. Topics that have the most recent average article publication year appear
as red in the HRM Map (e.g. “moderated mediation model” – average article publication year 2013.64, “Facebook” – avg. pub. year
2013, “work engagement” – avg. pub. year 2012.78), while topics that tended to have an older average article publication year
(e.g. “competing values framework” - avg. pub. year 1997) appear in cooler colors (e.g. blue).

A fourth view allows the viewer to explore the citation impact associated with each topic (see Fig. 4). In order to control for
the amount of time that passed since the article was published (i.e. the amount of time scholars have had to read and cite the
article), the citation count of each article is divided by the average citation count of all articles published in the same year. Afterwards, the citation impact of a topic is established by taking the average of the “normalized” citation scores of all articles the topic
occurred in (van Eck, Waltman, van Raan, Klautz, & Peul, 2013). Thus, topics that occur in articles with high citation rates, relative
to other articles published in the same year, have high scores and appear in red (e.g. “human capital resource” – average citation
impact = 5.10). Topics with citation impact scores below 1 tend to occur in articles with citation rates below the average for their
year of publication and appear in blue (e.g. “union representation” – avg. cit. impact = 0.47).
4. Review of the HRM field
In this section, we go into greater detail to provide 1) observations of the overall topic structure of the HRM field, and 2) a
systematic review of each major topic area identified in the network visualization of the map (Fig. 1). In particular, our analysis
of topic co-occurrence across 12,157 HRM articles over the past 23 years identifies five major HRM topic clusters: Strategic HRM
(Cluster 1: Red), Experiencing HRM (Cluster 2: Green), Employment Relations (Cluster 3: Blue), International HRM (Cluster 4:
Yellow), and Assessing People (Cluster 5: Magenta).4
4.1. Structural observations of the field
As can be seen in Figs. 1 and 2, the HRM Map reveals a number of interesting structural features of the field that could only
have been guessed at by scholars to date. In particular, nearly 15 years ago, Wright and Boswell (2002) asserted that a “micromacro” divide existed in HRM, and that HRM needed to “desegregate”. The network visualization in Fig. 1 reveals topics associated
with organizational-level issues on the left side of the map (e.g. Strategic HRM) and topics associated with individual-level issues
4
To name the five clusters, we drew on three sources. First, a focus group was conducted at an international conference of HRM scholars. Scholars were provided a list
of the most frequently occurring “how”, “who”, “what”, and “where” terms, and the top five most cited articles associated with each cluster. Subsequently, scholars individually nominated names for each cluster. Second, we reviewed all terms in each cluster, as well as 50 highly cited and 50 random articles associated with each cluster, and examined their self-described topic domain. Third, we examined the top ten journal sources that most frequently publish research belonging to each cluster –
paying particular attention to journals uniquely associated with one cluster but not the others. This information was collated and discussed by the authors, who then
generated naming options and chose names for each cluster from the options.
376
M.P. Markoulli et al. / Human Resource Management Review 27 (2017) 367–396
on the right side of the map (e.g. Assessing People). As such, Fig. 1 supports the notion that “macro” to “micro” is a useful dimension for describing one way in which HRM topics vary. However, a macro-micro divide would appear in the Fig. 2 density view as
two red islands of high research intensity divided by a green or yellow low research intensity gulf – indicating disconnectedness
between these topic areas. In contrast, Fig. 2 reveals a high degree of research intensity on a host of topics having to do with
meso-level issues (e.g. “training”, “organizational culture”, “reward system”, “organizational policy”) that are actively linking
macro and micro topic areas. Many of these meso-level issues are found in the Employment Relations and International HRM clusters. As such, our analysis suggests that the notion of a strong macro-micro divide does not accurately describe the HRM field's
intellectual structure.
The HRM Map also reveals a significantly different topic taxonomy that than prior, more impressionistic descriptions of the
HRM field. For example, Martín-Alcázar et al. (2008) attempted to describe the HRM field by proposing a Venn diagram showing
three overlapping topic areas: Functional, International, and Strategic HRM. The HRM Map provides mixed support for this characterization. Our empirical analysis of topic relations reveals that International HRM and Strategic HRM are indeed major topic
domains that partially overlap (as can be visually discerned from the proximity of the yellow and red clusters on the map, as
well as the occasional interspersion of yellow topics within the predominately red topic space, and vice-versa). However, a Functional HRM cluster does not emerge as a distinct topic area. Rather, Functional HRM topics (e.g. compensation, selection, and training) evidence a more distributed pattern of co-occurrence, and are spread across three topic clusters not previously identified by
Martín-Alcázar and colleagues – namely, the topic clusters: Assessing People, Experiencing HRM, and Employment Relations.
The HRM Map also offers mixed support for the topic categories proposed previously by Fernandez-Alles and Ramos-Rodriguez
(2009), who assessed articles from a single HRM journal from 1985 to 2005. In particular, both the HRM Map and Fernandez-Alles
and Ramos-Rodriguez (2009) identify five topic clusters, one of which is International HRM. However, there are also significant differences. First, Fernandez-Alles and Ramos-Rodríguez appear to overlook Employment Relations as a major HRM topic area, which our
bibliometric analysis suggests is comparable in size and degree of topic coherence to International HRM. Second, our scientometric analysis of topic relations in HRM scholarship suggests that three of the topic categories they identify (i.e. HR and Firm Performance; Strategy,
Structure, and Environment; and Strategic Management of HR) comprise an omnibus Strategic HRM category – also comparable in size
and degree of topic coherence to International HRM. Third, our analysis finds that the topic category Fernandez-Alles and RamosRodríguez refer to as “Culture and Motivation” is comprised of topics that more typically “belong” to two different categories – i.e.
Assessing People and Experiencing HRM – given their pattern of topic relations in HRM scholarship. The topic categories identified by
Fernandez-Alles and Ramos-Rodríguez may be more reflective of the single journal source these authors were drawing from at the
time, rather than the topic structure of the general HRM literature as it stands a decade later.
Given the more comprehensive article sample and rigorous methodologies employed to produce this analysis, we suggest that
the HRM Map provides a more accurate and complete depiction of the intellectual content and structure of the HRM field. In particular, we suggest that the five topic areas identified in this analysis offer more a descriptively accurate taxonomy of HRM scholarship for organizing one's understanding of the field, and can aid in the interpretation and generation of new scholarly insights
(e.g. McGarty, 1999; Weick, Sutcliffe, & Obstfeld, 2005) (as discussed in greater detail below). As these HRM topic categories have
been either a) neglected in prior field-level reviews, or b) described based on authors' impressionistic assessments – rather than a
systematic analysis – we now turn our attention to systematically describing the five major HRM topic areas.
4.2. Topic cluster reviews
As noted above, a key innovation of the HRM Map is that it not only identifies broad topic clusters, but also details the specific
topic contents within each cluster. Thus, in the reviews below, we systematically describe the topic contents of each of the five
HRM topic areas. To review each cluster, the topics within that cluster were organized into themes. Then, articles belonging to
each cluster were examined to identify whether a stream of articles associated with each theme was present.5 To ensure no
major themes were missed, we considered 50 highly cited articles and 50 random articles associated with each cluster. In presenting the reviews below, we aim to offer a foundational, empirically grounded review of the major topic areas of the HRM field.
By way of an overview of the HRM topic clusters, Table 3 presents the how, who, what, and where terms associated with the
largest number of articles in each of the five HRM topic areas. Table 4 indicates a) the top trending topics for each cluster, defined
as topics with the most recent average article publication date, and b) the topics that occur in articles with high relative citation
rates. Table 5 indicates the most frequently cited articles that strongly “belong” to each cluster. Table 6 indicates the top 10 journals
publishing research strongly associated with each cluster. Figs. 5 and 6 reveal the comparative growth of each of the five topic
clusters in terms of a) number of articles produced, and b) percentage of the field's scholarship from 1992–2014 (the last complete year for which we have article data). We note that each major topic literature has grown markedly over the past two decades, at compounding growth rates of 9% (Strategic HRM), 12% (Experiencing HRM), 8% (Employment Relations), 11%
(International HRM), and 9% (Assessing People).
4.2.1. Cluster #1: Strategic HRM (Red)
The Strategic HRM cluster focuses on understanding the relationship between HRM systems and firm performance. Key approaches developed to understand this relationship include: universalistic, contingency, configurational, and contextual (cf.

b
Delery & Doty, 1996). Several prominent scholars have examined the differences between these approaches (Martín-Alcázar,
Romero-Fernández, & Sánchez-Gardey, 2005). For example, Boxall and Purcell (2000) reviewed the Strategic HRM debate between the “best practices” model, which focuses on the efficacy of independent practices (i.e. employs a universalistic perspective), and the “best fit” model, which takes internal and external factors into consideration (i.e. using a contingency,
configurational, or contextual perspective). They concluded that few practices are effective independent of context.
Relatedly, map terms like “compensation policy/practice/system/strategy” reveal that the Strategic HRM cluster considers how
compensation policies either support or contradict firm strategies. Drawing largely on archival data across many firms, articles associated with this cluster consider which compensation polices allow firms to pursue an innovative strategy (Yanadori & Marler,
2006), as well as how compensation practices fit with firms' other organizational practices such as empowerment (Chênevert &
Tremblay, 2009), integrated manufacturing systems (Shaw, Gupta, & Delery, 2001), and Enterprise Resource Planning (da Silveira,
Snider, & Balakrishnan, 2013).
Another major subtheme in the Strategic HRM cluster is how HR practices affect a firm's capacity to change in response to
strategic imperatives. There are many terms associated with this underlying theme, including “change management”, “innovation
capability”, “organizational learning capability”, “external flexibility”, “functional flexibility”, and “learning agility” (DeRue,
Ashford, & Myers, 2012). Specifically, HR practices nominated as having a causal connection to the ability to explore and adapt
include external staffing, selection based on creativity and unique backgrounds, employing consultants, comprehensive training,
job rotation, structural empowerment, long-term career development, “up or out” promotion systems, and group/firm based
pay (Chang, Gong, Way, & Jia, 2013; Jaw & Liu, 2003; Martínez-Sánchez, Vela-Jiménez, Pérez-Pérez, & de Luis Carnicer, 2011;
Swart & Kinnie, 2010). The Strategic HRM cluster also deals with the dark side of change – i.e. downsizing – as reflected in
terms like “[organizational] downsizing”, “workforce reduction”, “outsourcing”, and “corporate restructuring”. In particular, a number of articles focus on how HR can ensure that downsizing is done in a way that is humane, retains strong employees, maintains
the motivation of “survivors”, and preserves product quality (Cameron, 1994; Cascio & Wynn, 2004; Lam & Reshef, 1999).
Finally, the Strategic HRM cluster explains firm performance as partly a function of its social and human capital, as illustrated
by map terms such as “firm specific human capital”, “intellectual capital”, “organizational capital”, “relational capital”, and “social
capital”. Some of the most cited articles associated with this cluster use a perspective grounded in the resource-based view,
human capital theory, and transaction cost economics (e.g. Huselid, Jackson, & Schuler, 1997; Lepak & Snell, 1999, 2002;
Youndt, Subramaniam, & Snell, 2004). These articles conceptualize employees as a form of economic “capital”, and consider HR
practices as drivers of this capital. Key articles in this topic area typically suggest that firms should invest in HRM programs
that increase and retain firm-specific human capital (Crook, Todd, Combs, Woehr, & Ketchen, 2011, p. 443), as well as the absorption and retention of knowledge (S. C. Kang, Morris, & Snell, 2007). These HR practices are expected to contribute to firm

performance, innovation, and competitive advantage through the theoretical mechanisms of inimitability and intangibility (Hatch
& Dyer, 2004; Wright, Dunford, & Snell, 2001).
4.2.2. Cluster #2: Experiencing HRM (Green)
The second cluster, which we call “Experiencing HRM”, primarily consists of topics associated with employees' perspectives,
attitudes, and behaviors. The articles associated with this cluster deal with how HR elements influence employees' experiences
at work. Specifically, the typical article in this cluster links aspects of HR (e.g. flextime) to a) employee experiences (e.g. perceived
organizational support), and/or b) employee attitudes (e.g. job satisfaction). These experiences and work attitudes are sometimes
linked to individual-level outcomes, including: organizational citizenship behavior, voluntary turnover, withdrawal behavior, and
work effort. Illustrative examples are provided below.
Key types of employee experiences from this cluster include stress, (in)justice, psychological support, and work-life balance.
First, a literature on HR and stress suggests that jobs designed to be more demanding than employees can cope with are experienced as stressful. This literature goes under the label “job demands resources model” (for a review, see Bakker, Demerouti, &
Verbeke, 2004). Second, a literature on (in)justice suggests that HR practices and HR messages convey implicit promises to employees, and that employees are angered when these “psychological contracts” are violated (Sims, 1994). Third, a number of articles suggest that HR policies – e.g. formalized career mentoring, participation in decision making, fair rewards, and growth
opportunities – can affect whether employees feel psychological support from their organizations and direct supervisors (D. G.
Allen, Shore, & Griffeth, 2003). Fourth, HR elements like flextime, telecommuting, childcare support, and jobs that do not demand
long hours can reduce work-family conflict and lead to work-life balance (T. D. Allen, 2001; Raghuram & Wiesenfeld, 2004; White,
Hill, McGovern, Mills, & Smeaton, 2003).
Articles associated with this cluster also consider how HR practices affect important job attitudes, including job satisfaction, job
involvement, employee engagement, morale, loyalty, and organizational commitment. For example, a number of studies indicate

that high-involvement HR practices (e.g. nonmonetary recognition, competency development, fair rewards, information-sharing)
are positively related to work attitudes, and ultimately employee behavior (Paré & Tremblay, 2007). A final theme linking HR policies to work attitudes is the HR process approach, which argues that employees' attitudes are influenced by how an HRM policy
is implemented, explained, and made sense of (Li, Frenkel, & Sanders, 2011; Nishii, Lepak, & Schneider, 2008).

4.2.3. Cluster #3: Employment Relations (Blue)
While the Employment Relations cluster often adopts the same economic assumptions as the Strategic HRM cluster, it is decidedly less allied with management. Instead, articles in this cluster often adopt a pluralist perspective, which presumes that conflict between workers and management is the inevitable result of contradictory interests (Godard & Delaney, 2000). The pluralist
perspective is contrasted with the unitarist perspective. Unitarists argue that management and employees share common cause,
and conflicts are the results of poor communication and outdated management philosophies (P. Thompson, 2011). Reflecting
both sides of the debate, frequent topics in this cluster include: “government”, “unionization”, “employment relationship”, “employee involvement”, “employee voice”, “employee participation”, and “managerial control”.
The articles associated with the Employment Relations cluster often look to government, unions, and labor markets to limit the
extent of managerial control (P. Thompson, 2011). Pluralist scholarship suggests that fair worker treatment requires collective
bargaining and collective voice mechanisms (Batt, Colvin, & Keefe, 2002). As such, pluralists lament the shift away from collective
voice mechanisms (e.g. unions) in many countries and industries (Brewster, Croucher, Wood, & Brookes, 2007). Indeed, many articles associated with Employment Relations are often critical of creeping managerialism, and warn against HRM scholars becoming “servants of power” (Delbridge & Keenoy, 2010). In retort, these articles advocate a Critical HRM perspective.
As such, there is substantial critique of High Performance Work Systems (HPWS). This somewhat fuzzy concept has to do with
synergistic bundles of HR practices that tend to lead to high performance (Boxall & Macky, 2009). The fuzziness of this concept
derives from the reality that which particular bundles of HR practices lead to high performance (which is difficult to define in
itself) is a function of our evolving understanding of causal relationships in the field and may vary across countries, governmental
systems, cultures, economic climates, and firm strategies. As a result, there is no agreed upon list of high performance HR practices (Boxall & Macky, 2009). This leads some scholars to include as HPWS practices that mainly serve to intensify work (e.g.
pay for performance, dismissal of low performers). Such work intensification policies may improve performance at the expense
of worker welfare and job security (Godard, 2004). More broadly, Kaufman (2010, p. 308) suggests that the Strategic HRM literature disregards the potentially negative outcomes of HPWS for employees – i.e. “‘greater motivation’ = work intensification?;
‘more flexibility’ = less job security?” – and argues that it is morally misguided to view labor primarily as a form of capital.
While the pluralist and unitarist perspectives differ in the value they place on collective voice mechanisms (e.g. unions) and
work intensification, both sides agree that individual voice mechanisms can help ensure fair treatment (Dundon, Wilkinson,
Marchington, & Ackers, 2004). Drawing on empirical findings showing that employee voice is associated with job satisfaction, organizational commitment, promotion of organizational diversity, and other positive outcomes, scholars recommend that all HRM
professionals should foster employee voice opportunities (S. J. Wood & de Menezes, 2011; S. J. Wood & Wall, 2007).
In addition to high involvement practices, this literature also contains a number of studies attempting to assess whether employees and employers benefit from training. While some studies show that only employees benefit (in the form of increased
wages) (e.g. Schone, 2001), most show that employers also benefit meaningfully (in the form of increased productivity and
profits) (e.g. Colombo & Stanca, 2014; Lopes & Teixeira, 2013). Given that employees benefit from training, a number of studies
382
M.P. Markoulli et al. / Human Resource Management Review 27 (2017) 367–396
have demonstrated that organized labor (e.g. unions) “bargain for skills”; this, in turn, increases the prevalence and intensity of
training (Heyes & Stuart, 1998). Of course, not all training programs are equally effective, and a number of studies associated
with this cluster attempt to identify which training methods are most effective in particular situations (e.g. Martin, Kolomitro,
& Lam, 2014). Related topics in the map include “training”, “job training”, “training opportunity/policy/system”.
A final major subtheme in the Employment Relations cluster is “nonstandard employment”, which is also called contingent
work, atypical work, or peripheral work (Ashford, George, & Blatt, 2007). Topics related to this theme in this cluster include
“[temporary] agency worker”, “employment agency”, “part time worker”, and “temporary contract/employment/worker”. Associated articles focus on the macro causes and micro consequences of nonstandard work. Proposed macro causes of nonstandard
work include permissive government policy (Sahadev & Demirbag, 2011), economic recession (de Graaf-Zijl & Berkhout, 2007),
a dynamic competitive environment and organizational strategies focusing on low-costs or adaptability (Purcell, Purcell, &
Tailby, 2004), and the absence of family-friendly practices (Heywood, Siebert, & Wei, 2011). Micro-level consequences of nonstandard work for workers include less job security (Feldman, Doerpinghaus, & Turnley, 1994), lower wages (Underhill, 2010), less
training, and greater social marginalization (Feldman et al., 1994; Hoque & Kirkpatrick, 2003), but perhaps also provide a gateway
to permanent employment (Berton, Devicienti, & Pacelli, 2011). For firms, provisional evidence suggests that utilization of nonstandard workers has a non-linear relationship with profits, being valuable up to a point and then becoming dysfunctional
(Roca-Puig, Beltrán-Martín, & Segarra-Ciprés, 2015). Taken together, this evidence on non-standard employment is largely consistent with the pluralist view – i.e. that firm profits and worker welfare are in tension. However, some scholars are hopeful that
morally responsible organizations can treat temporary workers in ways that are both ethical and financially rewarding (Bolton,
Houlihan, & Laaser, 2012; Zhang, Bartram, McNeil, & Dowling, 2014).
4.2.4. Cluster #4: International HRM (Yellow)
Since 2003, there has been a rapid increase in research on topics relating to how HRM practices and their application may vary
across countries (see Figs. 5 and 6). This suggests that, with the rise of globalization, there is an increasing interest in developing
international HRM policies. Three major themes are considered below: expatriation, country specific HR, and firm-level international HRM.
In the International HRM literature, there is a substantial amount of work on how multinationals can choose an appropriate
balance of third country nationals, host country nationals, and parent country nationals in their subsidiaries (Tarique, Schuler,
& Gong, 2006; Tharenou & Harvey, 2006). In relation to parent country nationals, special attention is paid to expatriation and repatriation of employees. This is shown in the HRM Map by topics in this cluster such as “expatriate”, “expatriate assignment”, and
“cross cultural adjustment”. Some articles in this cluster consider the nature of international assignments, highlighting the difference between long-term, “conventional” expatriate assignments versus short-term overseas assignments (Collings, Scullion, &
Morley, 2007). A relatively new area of inquiry is the study of self-initiated expatriation versus assigned (organizational) expatriation (Biemann & Andresen, 2010; Jokinen, Brewster, & Suutari, 2008; Peltokorpi & Froese, 2009). Some “comparative” articles
contain findings showing that self-initiated expatriates adjust better to cultural and environmental differences in host countries
than organizational expatriates (Doherty, Dickmann, & Mills, 2011). A related topic is how expatriates' cultural intelligence and
cross-cultural adjustment are affected by various HRM practices, such as the impact of work-life balance policies, compensation,
and rewards (Collings et al., 2007; Malek & Budhwar, 2013; Puck, Kittler, & Wright, 2008). Finally, repatriation is studied in relation to knowledge transfer (Lazarova & Tarique, 2005), as well as promotion and retention of the repatriated employees (Kraimer,
Shaffer, & Bolino, 2009; Suutari & Brewster, 2003).
The HRM Map also indicates that certain locales are more frequently studied in the International HRM literature. Of these,
China (a topic of 555 articles) is the most prevalent. Relatedly, many articles belonging to this cluster consider HR practices in
particular countries. For instance, many international HRM researchers have studied the application of “Western” HRM practices
in MNCs operating in China (for reviews, see Cooke, 2009; Kim, Wright, & Su, 2010). This may be due to the increased proliferation of international business operations occurring in China. A large number of articles are also associated with location topics
such as “Japan”, “Europe”, and “Korea”. Location topics associated with a comparatively small number of articles (e.g. Africa, Central and South America, India, Russia, and the Middle East) may suggest emerging opportunities to consider HRM differences in
these regions (Afiouni, Ruel, & Schuler, 2014; Kamoche, Chizema, Mellahi, & Newenham-Kahindi, 2012). Given that HRM practices
in these regions can vary dramatically from those in more frequently studied countries, research from these regions may reveal
new local HR practices for HRM scholars to investigate, and provide opportunities to examine the effectiveness of established
HRM approaches in new contexts.
Moving toward the top of the International HRM cluster, the topics begin to focus on more firm-level and societal-level factors.
Many of the representative articles at this level of analysis that are associated with the International HRM cluster are grounded in
institutional theory, as represented by topics such as “institutional environment” and “institutional theory”. An institutional perspective on International HRM suggests that HRM practices are a function of norms, laws, and political structures that vary across
countries (Bjorkman, Fey, & Park, 2007; Ferner, Almond, & Colling, 2005). A particular question of debate is the extent to which
institutions are converging, such that there exists a set of “global” HR practices (Brewster, Wood, & Brookes, 2008; Gerhart & Fang,
2005). Relatedly, a great deal of attention has been paid to whether subsidiaries of multinationals should adopt HR policies consistent with local institutions, or whether headquarters' HR practices should be applied to local subsidiaries (Brewster & Suutari,
2005; Ferner et al., 2011; Gamble, 2003). Findings of these articles point out that many MNCs choose to tailor their HR practices
to suit the locale they operate in (i.e. localization); however, in certain industries and locales, global standardization can also be
appropriate, particularly when the so-called “country of origin effect” is dominant.

4.2.5. Cluster #5: Assessing People (Magenta)
The Assessing People cluster contains topics relating to how HR practices can assess and respond to the differences between
people. Major subthemes in this cluster have to do with employee selection, assessing job performance, and individual differences.
A first subtheme in this topic cluster focuses on recruiting and assessing potential job applicants. Recruitment research includes studies on the kinds of people attracted to different kinds of organizations (Swider, Zimmerman, Charlier, & Pierotti,
2015), and internal and external recruitment methods (Breaugh, 2008). Articles on selecting employees focus on identifying optimal hiring procedures (Sackett & Lievens, 2008). Many of these articles have to do with the validity of personality and cognitive
ability tests used to select applicants (Ones, Dilchert, Viswesvaran, & Judge, 2007; Ones & Viswesvaran, 1996; Salgado, 1997). Beyond these factors, this cluster contains articles considering: whether (structured) interviews are a valid selection technique despite impression management attempts by job applicants (Roulin, Bangerter, & Levashina, 2015), whether psychometric selection
tests can be trusted despite applicants' attempts to “game the test” (e.g. Blickle, Momm, Schneider, Gansen, & Kramer, 2009;
Ellingson, Sackett, & Connelly, 2007), and the extent to which hiring decisions both are and should be based on interviewers' subjective person-organization fit assessments (Cable & Judge, 1997). In addition, a number of articles related to “equal employment
opportunities” consider whether hiring practices result in employment discrimination against women (Patterson & Walcutt,
2014), ethnic minorities (Hiemstra, Derous, Serlie, & Born, 2013), immigrants (Dietz, Joshi, Esses, Hamilton, & Gabarrot, 2015),
and those with disabilities (Ren, Paetzold, & Colella, 2008).
A second subtheme within this cluster has to do with assessing performance – e.g. topics like “supervisor rating”, “performance appraisal”, and “job performance rating”. Most articles on this theme focus on performance appraisal systems and feedback strategies (Levy & Williams, 2004). Some of these articles consider employees' reactions to being appraised and given
feedback (Culbertson, Henning, & Payne, 2013). Others are about how performance appraisals can be designed by HR to minimize the potential for discrimination (Hennessey & Bernardin, 2003) and maximize demographic diversity. Still others are
about alternatives to traditional appraisal techniques – e.g. feedforward interviews, which attempt to create a dialogue with employees about how they can create contexts where they will be more successful (Budworth, Latham, & Manroop, 2015; Kluger &
Nir, 2010).
Related to assessing job performance, a third subtheme revolves around personality and cognitive ability. This theme
links differences in personality and cognitive ability to assessments of core job performance (Barrick, Mount, & Judge,
2001; Schmitt, 2014), citizenship behaviors (Greenidge & Coyne, 2014), and counterproductive workplace behaviors (Salgado,
2002). Although much of this research describes personality in terms of the Big Five (i.e. openness, conscientiousness,
extraversion, agreeableness, and emotional stability), recent studies have considered the predictive ability of both more
nuanced (Goertz, Hülsheger, & Maier, 2014) and more aggregated personality dimensions (Van der Linden, te Nijenhuis,
& Bakker, 2010).
5. Using the HRM Map and reviews to identify future research opportunities
This objective, systematic analysis of “where we are” as a field can provide a foundation for identifying promising research opportunities “where could we go next”. In a field as big and topically varied as HRM, there are an enormous number of potential
research opportunities. Which of these opportunities are actually pursued depends on the interests and capabilities of specific researchers, as well as their ability to detect these opportunities. The downloadable HRM Map can assist researchers by improving
their ability to detect attractive research opportunities. The basic process we recommend to accomplish this is called abduction.
Abduction is a mode of reasoning that involves noting contradictions between observed evidence and one's theories/intuitions,
and then using the resulting surprise as motivation for conjecture and future inquiry (Fann, 2012). Abduction has been argued
to be at the heart of creative research, and has been called the logic of discovery (Shepherd & Sutcliffe, 2011; Van Maanen,
Sørensen, & Mitchell, 2007).
In this context, the downloadable map (supplemented by the above review) can be used as a basis for abduction. Scholars are
encouraged consider how elements of the HRM Map contradict their theories/intuitions about HRM phenomena, and to use the
resulting surprise as motivation for conjecture and additional inquiry. To be more specific, we highlight how the HRM Map
could be the basis for two different kinds of abductive inquiry: 1) using surprises about the placement of terms relative to
other terms to discover opportunities for subfield integration, and 2) using surprises about the size or absence of terms to uncover
interesting, underdeveloped research topics. Each is considered in turn.
First, when one looks at the details of the downloadable, dynamic HRM Map, the relative placement of topics can yield interesting surprises – particularly when topics that seem logically or phenomenologically related are far apart on the map. This implies that there is relatively little research linking these topics, and their co-examination may yield valuable new research
opportunities and insights. Indeed, some of the most impactful scholarly contributions come from “borrowing or mixing … concepts or insights from two or more subfields within a discipline” (Leahey & Moody, 2014, p. 230). By considering the different
major topic clusters reviewed above and presented in the HRM Map it is possible to identify potentially related topics that
have little to no integration in HRM scholarship thus far. For example, building on our own backgrounds, we were surprised to
note the considerable distance in the HRM Map between topics having to do with employee personality (in the Assessing People
cluster) and employee compensation (in the Strategic HRM cluster). This distance is surprising given that it seems intuitively
plausible that personality is likely to be strongly related to which compensation schemes are preferred, and how specific compensation schemes impact employee motivation. And indeed, a scan of the HRM literature suggests that only a small amount of scholarship has considered these fundamental and practically relevant questions (Cable & Judge, 1997; Mitchell & Mickel, 1999). Given
384
M.P. Markoulli et al. / Human Resource Management Review 27 (2017) 367–396
the diverse backgrounds HRM scholars can bring when viewing the HRM Map, and the many thousands of potential combinations
of topics that could be explored, we expect that there are likely to be numerous opportunities for valuable, boundary-spanning
research discoverable through abduction with the HRM Map and reviews presented above.
Second, examining the number of articles associated with each topic in the HRM Map can also yield surprises. In particular,
HRM topics that may be greatly emphasized in teaching students or in talking with practitioners are often surprisingly small or
altogether absent from the map. As such, one way for future research to make truly novel contributions may be to research activities HR professionals are regularly involved in, but are not on the map – e.g. social media policies, terminating employees, office space design and allocation, workforce analytics, workplace substance abuse, employees who have been domestically abused,
employee assistance programs (EAPs), office romance, or Human Resource Information Systems. While there are a few studies on
each of these topics (e.g. Gammie, 1997; Milne & Blum, 1998; Pierce & Aguinis, 2013; Strohmeier, 2007; M. S. Wood & Karau,
2009), none of these areas have received substantial attention. As noted below, these topics are of considerable interest to practitioners, and raise a number of interesting theoretical questions. As such, they are likely to be areas where future research could
make major discoveries with applied relevance.
6. Comparative topic analysis of HRM scholarship vs. an HR practitioner-oriented outlet
A rigorous, systematic analysis of the content of HRM scholarship can offer a rich foundation for comparing “what is” to “what
could be”. In particular, for some time, scholars have been raising concerns about discrepancies between the topics considered in
HRM scholarship and the topic interests of HR practitioners (e.g. Deadrick & Gibson, 2007, 2009; Rynes et al., 2007). However,
attempts to identify the topic gaps between HRM scholarship and the interests of practitioners to date have had two significant
limitations.
First, prior attempts to compare HRM scholarship to practitioner interests have been substantially limited by the article samples used to represent the HRM field. For example, Deadrick and Gibson (2007) conducted important work in this area comparing
a sample of 1665 “academic” articles from two journals to 2691 “practitioner” articles from 1986–2005. While the number of articles in their sample is high relative to other analyses of HRM, it is only a fraction of the HRM literature overall, and thus not
necessarily representative of the field's full topic content. Thus, it is unclear whether the discrepancies they identify are an artifact
of the two particular academic journals they chose to draw articles from (i.e. Journal of Applied Psychology and Personnel Psychology). For example, Deadrick and Gibson note a significant gap between practitioner interest in Strategic HRM and the amount of
Strategic HRM research. And yet, as can be seen in Table 6, JAP and Personnel Psychology are not major outlets for Strategic HRM
research. Rather, International Journal of Human Resource Management and Human Resource Management are the key outlets for
Strategic HRM scholarship.
Second, the methodology for comparing academic and practitioner-oriented HRM to date has been considerably limited. For
example, similar to many HRM reviews before them, Deadrick and Gibson (2007) categorize the articles in their sample into
49 author-generated subcategories, nested in 15 larger categories – the latter of which were the basis for reporting discrepancies.
Identifying discrepancies between research and practice at the level of 15 overarching categories (e.g. Strategic HRM, International
HRM) offers comparatively little direction for scholars working at the topic-level as to which specific topics warrant greater
attention.
In contrast, by using bibliometric methods, we are able to provide a substantially improved research-practice topic discrepancy
analysis. In particular, below, we a) analyze larger and more up-to-date samples of both HRM scholarship (i.e. 12,157 HRM articles) and practitioner-oriented articles (i.e. 6114 articles), b) use bibliometric term identification to systematically identify the
specific topic contents of these literatures, and c) conduct a topic-level discrepancy analysis to identify the particular subjects
of interest to practitioners that have the largest discrepancy with HRM scholarship. By providing specific insights about potentially
under-served practitioner interests at the topic level (rather than at the level of broad topic areas), we can offer more detailed
specification of where future research efforts can be directed to help bridge the research-practice divide.
6.1. Sample
For this analysis, our aim was to compare the topic content of HRM scholarship with the interests of HR practitioners. As a
proxy for practitioners' interests, we identified the Society for Human Resource Management's publication HR Magazine as a
key outlet that caters to the interests of HR practitioners. According to a brand audit for HR Magazine, it is “the most widely
read publication in the human resources sector, especially among senior-level professionals”, with a total qualified circulation
of 279,026, and with 108,783 executive and 108,375 manager-level subscribers (Society for Human Resource Management,
2015). Given its audience of HR practitioners, and clear incentive to cater to the interests of that audience, we suggest that HR
Magazine is a reasonable proxy for HR practitioners' interests. This is in line with prior scholarship which has used HR Magazine
as a proxy for the interests of practitioners (e.g. Deadrick & Gibson, 2007; Rynes et al., 2007). Thus, we analyzed the topic contents of the titles and abstracts of 6114 HR Magazine articles available in the ProQuest database for the period 1992–2015 as of
January 6, 2016. Peripheral content (e.g. book reviews, conference announcements, membership information) was excluded.
The topic content of the practitioner literature was compared to the topic content of the 12,157 HRM research article sample described previously.

385
6.2. Comparative topic analysis
The topic content of HR Magazine was compared to the topic content of HRM scholarship using a four-step process. First,
VOSviewer term identification (described previously) was used to identify noun phrases from the titles and abstracts of HR Magazine articles (van Eck & Waltman, 2011). Second, we calculated both a) the proportion of HR Magazine articles that referenced
each term in their title/abstract, and b) the proportion of scholarly HRM articles that mentioned each term. Third, the degree
of discrepancy in topic emphases between the two article sources was measured by subtracting the proportion of topic mentions
in the academic HRM sample from the proportion of topic mentions in the HR Magazine sample. Fourth, and finally, two of the
authors independently coded the terms were the most underemphasized in HRM scholarship relative to practitioner interest to
identify any noun-phrases that were not meaningful for exclusion (e.g. “way”, “addition”). Agreement between coders as to
which terms should be excluded was high (Cohen's kappa = 0.90), and discrepancies were resolved via discussion and coders'
examination of HR Magazine articles to determine whether the term in question was used in a meaningful way. From this process,
we identified the top 100 terms emphasized to a much greater degree in HR Magazine than in academic HRM.
6.3. Limitations
In using HR Magazine as a proxy for practitioners' interests, our analysis has some limitations. First, HR Magazine likely offers
an imperfect reflection of the interests of HR practitioners. As noted above, the audience for HR Magazine includes Society for
Human Resource Management members, and particularly senior-level HR professionals (Society for Human Resource
Management, 2015). Thus, this outlet likely caters to a particular subset of HR practitioners. While imperfect, this outlet has
been singled out as the most widely read HR practitioner-oriented periodical by far (Rynes et al., 2007), and its contents indicate
a strong orientation toward serving the needs of practitioners regarding the practicalities of HR in organizations, suggesting that it
offers a reasonable proxy for HR practitioners' interests. Relatedly, as reflected in some of the discrepant terms reported below,
the Society for Human Resource Management that publishes HR Magazine is based in the United States. As such, the topic content
of this outlet may more strongly represent the interests of HR practitioners in the U.S.
6.4. Topic discrepancy results
In this section, we discuss seven key themes in the 100 most discrepant terms emphasized more strongly in the HR practitioner literature (see Table 7). These themes consist of sets of terms on a similar topic, and highlight opportunities for future
HRM scholarship that more closely aligns with the interests of HR practitioners.
First, as can be seen in the top 100 most discrepant terms, key individual and collective actors involved in human resource
management are emphasized to a much greater degree in this practitioner oriented outlet – e.g. “company”, “employer”, “HR professional”, “HR executive”, “HR department”, “employee”, and “worker”. In particular, the practitioner literature places a much
stronger emphasis on company executives – and especially on the relationships between HR departments and the company executives who tend to be key gatekeepers of organizational resources (e.g. “CEO”, “board”, “senior vice president”, “officer”, “executive”, “director”, and “president”). Indeed, there appears to be a keen interest among practitioners about the relationship
between HR departments and company executives. Examples of HR Magazine articles evidencing this theme include: “What do
HR executives want from CEOs?” (Leonard, 1998), “Selling work-life agendas to CEOs” (Budd, 1994), and “Top 10 things HR
needs to know about CEOs” (Malloch, 1997). Such articles suggest a strong interest among HR practitioners in learning how to
garner support, cooperation, or compliance from company executives.
The magnitude of these discrepancies suggest that greater alignment with the interests of practitioners would entail more consideration of the key actors and stakeholders involved in HR activities, and the relationship between HR departments and resource
gatekeepers. In particular, one appealing avenue HRM scholars could pursue would be to examine the political upward, lateral,
and downward influence techniques that allow HR managers to create new initiatives and shape the capabilities of the organization. Such articles appear to be highly relevant to practice, and yet comparatively rare in HRM scholarship (though see Galang &
Ferris, 1997).
A second theme receiving comparatively greater emphasis in the practitioner literature pertains to the financial aspects of HR
practice. Illustrative terms appearing to a comparatively greater degree in the practitioner literature include: “cost”, “money”, “expense”, “bottom line”, “dollar”, “budget”, “saving”, and “productivity”. In the main, the practitioner-oriented articles on this theme
focus on how to financially justify different kinds of HR initiatives, policies, and services. Exemplars of such articles in HR Magazine
include “Healthy workers improve the bottom line” (McShulskis, 1997), “Connecting the organizational pulse to the bottom line”
(about employee surveys) (Garvey, 2004), “Figuring incentive plans' ROI” (Sammer, 2006), “Calculate the return on your investment for better budgeting” (O'Connell, 1995a), and “Share your worth: Talking numbers with the CEO” (Sheley, 1996).
If HRM scholars wanted to pursue this theme to align with the interests of practitioners, they could re-engage with classic
works on utility analysis (Cascio, 2000; Schmidt & Hunter, 1998), which attempt to estimate the financial consequences of various
HR policies and initiatives. The evidence from such scholarship could both guide and legitimate various HR initiatives. And yet,
utility analysis has been relatively neglected by the academic HRM community. Given the rise of Evidence Based Management,
and practitioner's comparatively strong interest in financial aspects of HR, perhaps it is time for a revival of utility analysis in
HRM scholarship.
