Regis College Suicide Attempt Case Study
Suicide Case Study AssignmentCase HistoryMr. C is a 35-year-old Hispanic male with a long-standing history of mental illness. He was admitted to an inpatient psychiatric facility following a severe suicide attempt. He stated that he had been feeling progressively more depressed during the past three months and had been having an increase in suicidal thoughts over the past week. He felt tired most of the time and had problems concentrating. He felt hopeless about his life, found his job and personal life unfulfilling, and worried a lot about his critical financial situation. He was unable to think about reasons to continue living even though he has an extensive family living close by and several children from other partners. A few days prior to his admission, he went to a local casino for the first time in a few years and lost a significant amount of money. He then went back home, drank eight beers, and slit his wrists. He was found by a friend who stopped by the patient’s house to ask him to pay back some money he’d loaned the patient. The patient was brought to the hospital by ambulance, was medically stabilized, and was sent to the psychiatric unit. He reported passive suicidal ideation but felt safe in the hospital. Denied any homicidal ideation, thought, or plan, as well as any psychotic symptoms. Denied recent use of illicit drugs but admitted to having weed once every six months and drinking two beers and a couple shots of whiskey per day on a regular basis. Denied any past history of withdrawal symptoms. Psych Hx:Some elementary school problems with bullying and resulting encounters with school counselor. Also showed increasing problems with lying and stealing as a youngster. Recommended mental health counseling, but parents never followed up.One previous suicide attempt at age 27 resulting in three-day hospital stay. Intermittently compliant with outpatient treatment. Stopped taking escitalopram 20mg several months ago because of sexual side effects.Substances:Extensive abuse of cocaine since age 16. Drinking since age 14-15, mostly beer and whiskey. Has tried rehab several times but relapses shortly afterwards. No history of withdrawal. Currently doesn’t see his alcohol use as a problem and denies using any cocaine for the past two years, saying “it costs too much.”Legal:Two DUIs. Served six months for robbing a convenience store. Frequent arguments and fights which have necessitated police involvement but no arrests. Denies significant problems with gambling except for most recent event, during which he lost a lot of money.Family Psych Hx:Mother diagnosed with bipolar and somatization disorder; father has history of alcoholism.Social Hx:Third of four boys. Parents divorced when he was 5 years old. Inconsistent contact with father after that. Remembers father as drunk and physically abusive much of the time. Some trouble in school; kicked out after cheating incident. Never returned and only finished 11th grade. Never married, but many relationships, often short-lived, with three children that he knows of. Little contact with any of them. Works as truck driver. Has moved to several different places, often as a result of “trouble with paying back debts.”Medical Hx:Overweight, denies any medical issues. ED visit following accidental overdose of cocaine. Thought he was having an MI.LabsTotal Cholesterol: 220Triglycerides: 172SGOT (AST): 48SGPT (ALT): 36HGB: 16.5gm/dlHCT: 45%Na: 134K: 3.2Free T4: 1.1TSH: 3.2During his hospital stay, the patient presented as rather calm and charming with other patients. Always agreeable but gave little history about himself. Would not participate in divulging personal details of his life or talk about ways in which he might change in order to live a happier life.

GEB 3124 Rasmussen College Research Strategy Skills for Business Analysis Memo
CompetencyDevelop research strategy skills for business analysis.ScenarioYou are a manager at a small grocery store chain. In your role it is your responsibility to oversee all aspects of the day to day functioning of your store. This includes the customer experience, sales, management of employees, inventory, etc. Over the previous six months, you have identified a slow decline in sales. The home office has taken notice as well and is applying pressure to turn things around. You have been in this position for 3 years and plan to apply for a general manager position when one becomes available. However, if you are unable to increase your sales numbers, this will not be possible.In order to identify the cause in the decline, you will have to assess all aspects of your operation. Many factors can contribute to declining sales, such as customer service, price points, or even location. However, you are aware that a major competitor has recently began an online pick-up and delivery service to provide added convenience for their customers, and you believe this may be a contributing factor for the drop in your sales figures. You have mentioned this to the general manager and have gotten a lukewarm response. In order to stay competitive, you have decided to explore whether the lack of an online service component is affecting your in-store sales and what research strategies you will employ to make the determination.InstructionsYou have decided to formalize your concerns to management in the form of an internal MEMO. The MEMO will concisely identify the problem and include a review of the literature that analyzes pros and cons of adding an online pick-up and delivery service at your store. Taking the information, you have gleaned from the literature search, you will then identify the research strategies you will employ to determine whether adding the online services for your customers would increase sales.In Microsoft Word create the internal MEMO and include the following:Brief introduction that provides context for your inquiry including a persuasive argument for moving forward with your research.Statement of the business problem that includes a dependent and independent variable.A review of the literature that includes at least four references to published resources that includes both primary and secondary data (articles, annual reports, company websites, industry surveys)An analysis of the research strategy you will use to determine whether you will move forward with adding online services (survey, focus group, observation, content analysis, case studies etc.)A conclusion that explains the importance of moving forward with your research.

Overview
During the first 2 years, body size increases dramatically—faster than at any other time after birth. Rather than steady gains, infants and toddlers grow in little spurts. Body fat is laid down quickly in the first 9 months, whereas muscle development is slow and gradual. As with all aspects of development, children vary in body size and muscle–fat makeup. The best way to estimate a child’s physical maturity is by using skeletal age. Two growth patterns—cephalocaudal and proximodistal trends—describe changes in the child’s body proportions.
At birth, the brain is nearer than any other physical structure to its adult size, and it continues to develop at an astounding pace throughout infancy and toddlerhood. Neurons, or nerve cells, that store and transmit information, develop and form an elaborate communication system in the brain. As neurons form connections, stimulation becomes necessary for their survival. The cerebral cortex is the largest, most complex brain structure—accounting for 85 percent of the brain’s weight, containing the greatest number of neurons and synapses, and responsible for the unique intelligence of our species. At birth, the two hemispheres of the cerebral cortex have already begun to specialize, a process called lateralization. However, the brain is more plastic during the first few years than it will ever be again. Animal research and natural experiments with children who were victims of deprived early environments provide evidence for sensitive periods in brain development. Appropriate stimulation is key to promoting experience-expectant brain growth—the young brain’s rapidly developing organization, which depends on ordinary experiences. Experience-dependent brain growth, in contrast, occurs throughout our lives as a result of specific learning experiences. Rapid brain growth means that the organization of sleep and wakefulness changes substantially between birth and 2 years, but the social environment also plays a role.
Physical growth, like other aspects of development, results from the continuous and complex interplay between genetic and environmental factors. Heredity, nutrition, and emotional well-being all affect early physical growth. Dietary diseases caused by malnutrition affect many children in developing countries. If allowed to continue, body growth and brain development can be permanently stunted. Breastfeeding provides many benefits to infants, especially for those in the developing world where safe, nutritious alternatives are not widely available. Breastfeeding also helps protect against later obesity. Babies who do not receive affection and stimulation may suffer from nonorganic failure to thrive, which has symptoms resembling those of malnutrition but has no physical cause.
Babies come into the world with built-in learning capacities that permit them to profit from experience immediately. Classical and operant conditioning, habituation and recovery, and imitation are all important mechanisms through which infants learn about their physical and social worlds.
Like physical development, motor development follows the cephalocaudal and proximodistal trends. Babies’ motor achievements have a powerful effect on their social relationships. According to the dynamic systems theory of motor development, each new motor skill is a joint product of central nervous system development, movement capacities of the body, the child’s goals, and environmental supports for the skill. Cultural differences in infant-rearing practices affect the timing of motor development.
Perception changes remarkably over the first year of life. Hearing and vision undergo major advances during the first 2 years as infants organize stimuli into complex patterns, improve their perception of depth and objects, and combine information across sensory modalities. From extensive everyday experience, babies gradually figure out how to use depth cues to detect the danger of falling. According to Eleanor and James Gibson’s differentiation theory, perceptual development is a matter of detecting invariant features in a constantly changing perceptual world.
According to Piaget, by acting directly on the environment, children move through four stages of cognitive development in which psychological structures, or schemes, achieve a better fit with external reality. The first stage, called the sensorimotor stage, spans the first two years of life and is divided into six substages. In this stage, infants make strides in intentional behavior and understanding of object permanence until, by the end of the second year, they become capable of mental representation, as seen in their sudden solutions to sensorimotor problems, mastery of object permanence, deferred imitation, and make-believe play. Recent research suggests that some infants display certain understandings earlier than Piaget believed, raising questions about the accuracy of his account of sensorimotor development.
Information-processing theorists, using computer-like flowcharts to describe the human cognitive system, focus on many aspects of thinking, from attention, memory, and categorization skills to complex problem solving. With age, infants attend to more aspects of the environment and take information in more rapidly. In the second year, as children become increasingly capable of intentional behavior, attention to novelty declines and sustained attention improves. As infants get older, they remember experiences longer and group stimuli into increasingly complex categories. Also, categorization shifts from a perceptual to conceptual basis. Information processing has contributed greatly to our view of young babies as sophisticated cognitive beings. However, its greatest drawback stems from its central strength—by analyzing cognition into its components, information processing has had difficulty putting them back together into a broad, comprehensive theory.
Vygotsky believed that complex mental activities have their origins in social interaction. Through joint activities with more mature members of their society, children come to master activities and think in ways that have meaning in their culture.
Infant intelligence tests primarily measure perceptual and motor responses and predict later intelligence poorly. Speed of habituation and recovery to visual stimuli, basic information-processing measures, are better predictors of future performance. Home and child-care environments, as well as early intervention for at-risk infants and toddlers, exert powerful influences on mental development.
As perception and cognition improve during infancy, they pave the way for an extraordinary human achievement: language. The behaviorist perspective regards language development as entirely due to environmental influences, whereas nativism assumes that children are prewired with an innate language acquisition device to master the intricate rules of their language. The interactionist perspective maintains that language development results from interactions between inner capacities and environmental influences.
Babies begin cooing around 2 months, followed by babbling, which gradually reflects the sound and intonation patterns of the child’s language community. First words appear around 12 months, and two-word utterances between 18 and 24 months. However, substantial individual differences exist in the rate and style of early language progress. As toddlers learn words, they may apply them too narrowly (underextension) or too broadly (overextension), in part because their language comprehension develops ahead of their ability to produce language. Adults in many cultures speak to young children using child-directed speech, a simplified form of language that is well-suited to their learning needs. Deaf parents use a similar style of communication when signing to their deaf babies. Conversational give-and-take between adults and toddlers is one of the best predictors of early language development and academic success during the school years.
Although Freud’s psychoanalytic theory is no longer in the mainstream of human development research, his emphasis on the importance of the parent–child relationship was accepted and elaborated on by other theorists, notably Erik Erikson. Erikson believed that the psychological conflict of the first year of life is basic trust versus mistrust, and that a healthy outcome depends on the quality of the parent–child relationship. During toddlerhood, the conflict of autonomy versus shame and doubt is resolved favorably when parents provide appropriate guidance and reasonable choices. If children emerge from the first few years without sufficient trust and autonomy, the seeds are sown for adjustment problems.
All humans and other primates experience basic emotions—happiness, interest, surprise, fear, anger, sadness, and disgust—that have an evolutionary history of promoting survival. Emotions play powerful roles in organizing social relationships, exploration of the environment, and discovery of the self. Cognitive and motor development, caregiver–infant communication, and cultural factors all affect the development and expression of emotions.
Infants’ emotional expressions are closely tied to their ability to interpret the emotional cues of others. As toddlers become aware of the self as a separate, unique individual, self-conscious emotions—guilt, shame, embarrassment, envy, and pride—appear. Toddlers also begin to use emotional self-regulation strategies to manage their emotions. Rapid development of the cerebral cortex, sensitive caregiving, and growth in representation and language contribute to the development of effortful control, which is necessary for self-regulation.
Infants vary widely in temperament, including both reactivity (quickness and intensity of emotional arousal, attention, and motor activity) and self-regulation (strategies for modifying reactivity). Research findings have inspired a growing body of research on temperament, examining its stability, biological roots, and interaction with child-rearing experiences. The goodness-of-fit model explains how temperament and environment can together produce favorable outcomes when child-rearing practices match each child’s temperament while encouraging more adaptive functioning.
Attachment refers to the strong affectionate tie we have with special people in our lives that leads us to feel pleasure when we interact with them and to be comforted by their nearness in times of stress. By the second half of the first year, infants have become attached to familiar people who have responded to their needs. Today, the ethological theory of attachment, which recognizes the infant’s emotional tie to the caregiver as an evolved response that promotes survival, is the most widely accepted view. By the end of the second year, children develop an enduring affectionate tie to the caregiver that serves as an internal working model, a guide for future close relationships. Attachment security is influenced by opportunity for attachment, quality of caregiving, infant characteristics, and family circumstances. Babies form attachments to a variety of familiar people in addition to mothers—fathers, siblings, grandparents, and professional caregivers. Mounting evidence indicates that continuity of caregiving is the crucial factor that determines whether attachment security in early life is linked to later development. Children can recover from an insecure attachment history if caregiving improves.
During the first two years, knowledge of the self as a separate, permanent identity emerges, beginning with self-recognition—identification of the self as a physically unique being. Self-awareness is associated with the beginnings of empathy—the ability to feel with another person. Self-awareness also contributes to effortful control—the extent to which children can inhibit impulses, manage negative emotion, and behave in socially acceptable ways. Self-control allows toddlers to become compliant and acquire the ability to delay gratification.

With age, infants attend to more aspects of the environment and take information in more rapidly. In the second year, as children become increasingly capable of intentional behavior, attention to novelty declines and sustained attention improves. As infants get older, they remember experiences longer and group stimuli into increasingly complex categories. Also, categorization shifts from a perceptual to conceptual basis. Information processing has contributed greatly to our view of young babies as sophisticated cognitive beings. However, its greatest drawback stems from its central strength—by analyzing cognition into its components, information processing has had difficulty putting them back together into a broad, comprehensive theory.
Vygotsky believed that complex mental activities have their origins in social interaction. Through joint activities with more mature members of their society, children come to master activities and think in ways that have meaning in their culture.
Infant intelligence tests primarily measure perceptual and motor responses and predict later intelligence poorly. Speed of habituation and recovery to visual stimuli, basic information-processing measures, are better predictors of future performance. Home and child-care environments, as well as early intervention for at-risk infants and toddlers, exert powerful influences on mental development.
As perception and cognition improve during infancy, they pave the way for an extraordinary human achievement: language. The behaviorist perspective regards language development as entirely due to environmental influences, whereas nativism assumes that children are prewired with an innate language acquisition device to master the intricate rules of their language. The interactionist perspective maintains that language development results from interactions between inner capacities and environmental influences.
Babies begin cooing around 2 months, followed by babbling, which gradually reflects the sound and intonation patterns of the child’s language community. First words appear around 12 months, and two-word utterances between 18 and 24 months. However, substantial individual differences exist in the rate and style of early language progress. As toddlers learn words, they may apply them too narrowly (underextension) or too broadly (overextension), in part because their language comprehension develops ahead of their ability to produce language. Adults in many cultures speak to young children using child-directed speech, a simplified form of language that is well-suited to their learning needs. Deaf parents use a similar style of communication when signing to their deaf babies. Conversational give-and-take between adults and toddlers is one of the best predictors of early language development and academic success during the school years.
Although Freud’s psychoanalytic theory is no longer in the mainstream of human development research, his emphasis on the importance of the parent–child relationship was accepted and elaborated on by other theorists, notably Erik Erikson. Erikson believed that the psychological conflict of the first year of life is basic trust versus mistrust, and that a healthy outcome depends on the quality of the parent–child relationship. During toddlerhood, the conflict of autonomy versus shame and doubt is resolved favorably when parents provide appropriate guidance and reasonable choices. If children emerge from the first few years without sufficient trust and autonomy, the seeds are sown for adjustment problems.
All humans and other primates experience basic emotions—happiness, interest, surprise, fear, anger, sadness, and disgust—that have an evolutionary history of promoting survival. Emotions play powerful roles in organizing social relationships, exploration of the environment, and discovery of the self. Cognitive and motor development, caregiver–infant communication, and cultural factors all affect the development and expression of emotions.
Infants’ emotional expressions are closely tied to their ability to interpret the emotional cues of others. As toddlers become aware of the self as a separate, unique individual, self-conscious emotions—guilt, shame, embarrassment, envy, and pride—appear. Toddlers also begin to use emotional self-regulation strategies to manage their emotions. Rapid development of the cerebral cortex, sensitive caregiving, and growth in representation and language contribute to the development of effortful control, which is necessary for self-regulation.
Infants vary widely in temperament, including both reactivity (quickness and intensity of emotional arousal, attention, and motor activity) and self-regulation (strategies for modifying reactivity). Research findings have inspired a growing body of research on temperament, examining its stability, biological roots, and interaction with child-rearing experiences. The goodness-of-fit model explains how temperament and environment can together produce favorable outcomes when child-rearing practices match each child’s temperament while encouraging more adaptive functioning.
Attachment refers to the strong affectionate tie we have with special people in our lives that leads us to feel pleasure when we interact with them and to be comforted by their nearness in times of stress. By the second half of the first year, infants have become attached to familiar people who have responded to their needs. Today, the ethological theory of attachment, which recognizes the infant’s emotional tie to the caregiver as an evolved response that promotes survival, is the most widely accepted view. By the end of the second year, children develop an enduring affectionate tie to the caregiver that serves as an internal working model, a guide for future close relationships. Attachment security is influenced by opportunity for attachment, quality of caregiving, infant characteristics, and family circumstances. Babies form attachments to a variety of familiar people in addition to mothers—fathers, siblings, grandparents, and professional caregivers. Mounting evidence indicates that continuity of caregiving is the crucial factor that determines whether attachment security in early life is linked to later development. Children can recover from an insecure attachment history if caregiving improves.
During the first two years, knowledge of the self as a separate, permanent identity emerges, beginning with self-recognition—identification of the self as a physically unique being. Self-awareness is associated with the beginnings of empathy—the ability to feel with another person. Self-awareness also contributes to effortful control—the extent to which children can inhibit impulses, manage negative emotion, and behave in socially acceptable ways. Self-control allows toddlers to become compliant and acquire the ability to delay gratification.
