Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella

Dissertations, Theses, and Capstone Projects

In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta

Dissertations, Theses, and Capstone Projects

Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies …

Research Methods In Occupational Health Psychology, Irvin Sam Schonfeld, Chu-Hsiang Chang

Publications and Research

http://www.springerpub.com/occupational-health-psychology.html

Occupational Health Psychology (OHP) is a rapidly expanding interdisciplinary field that focuses on the science and practice of psychology in promoting and developing workplace health- and safety-related initiatives. This comprehensive text for undergraduate and graduate survey courses is the first to encompass a wide range of key issues in OHP. It draws from the domains of psychology, public health, preventive medicine,nursing, industrial engineering, law, and epidemiology to focus on the theory and practice of protecting and promoting the health, well-being, and safety of individuals in the workplace and improving the quality of work life.

The text addresses key psychosocial …

Burnout-Depression Overlap: A Study Of New Zealand Schoolteachers, Renzo Bianchi, Irvin Sam Schonfeld, Eric Mayor, Eric Laurent

Publications and Research

We examined the overlap of burnout with depression in a sample of 184 New Zealand schoolteachers. Burnout and depressive symptoms were strongly correlated with each other (r = .73; disattenuated correlation: .82) and moderately correlated with dysfunctional attitudes, ruminative responses, and pessimistic attributions. All the participants with high frequencies of burnout symptoms were identified as clinically depressed. Suicidal ideation was reported by 36% of those participants. Three groups of teachers emerged from a two-step cluster analysis: “low burnout-depression,” “medium burnout-depression,” and “high burnout-depression.” The correlation between the affective-cognitive and somatic symptoms of depression was similar in strength to the burnout-depression …

Consequences Of Job Stress For The Psychological Well-Being Of Teachers, Irvin Sam Schonfeld, Renzo Bianchi, Peter Luehring-Jones

Publications and Research

This chapter examines research on the relationship between job stressors and mental health (depressive symptoms, burnout, and mental disorders such as depression) in teachers. Teachers are exposed daily to job stressors (e.g., student disruptiveness) that have been linked to adverse mental health effects. Epidemiologic research indicates that when compared to members of other groups, teachers experience higher rates of mental disorder, although some studies question that conclusion. Large-scale studies indicate when compared to members of other occupational groups, teachers are at higher risk for exposure to workplace violence, with its adverse mental health consequences. Longitudinal research has linked teaching-related stressors …

Burnout Or Depression: Both Individual And Social Issue, Renzo Bianchi, Irvin Sam Schonfeld, Éric Laurent

Publications and Research

In view of the profound problems attached to the construct of burnout, we recommended in our that occupational health specialists focus on (job-related) depression rather than burnout to help workers more effectively. The phenomena of interest (burnout or depression) should not be confused with the perspectives (individual or social) adopted to elucidate those phenomena. Both burnout and depression are best explained through the interaction of social or external conditions with individual or internal dispositions.

Vital Exhaustion, Burnout, And Other Avatars Of Depression, Bianchi Renzo, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

In our view, there is a worrying tendency in psychology and medicine to let proliferate “depression-like” constructs—a transgression of the scientific canon of parsimony. The problem is not limited to vital exhaustion (VE). Burnout, a condition akin to VE, has been shown to problematically overlap with depression. Compassion fatigue, a condition that shows particularly blurred definitional contours, is also uncomfortably close to depressive symptomatology. The construct of neurasthenia may be part of this confusing trend as well, although neurasthenia has been elevated to the status of nosological category in the ICD. Construct proliferation jeopardizes knowledge growth by undermining theory building …

‘Burnout Syndrome’: From Nosological Indeterminacy To Epidemiological Nonsense, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

All in all, Imo’s review is undermined by the very research it relies on. We recommend that researchers interested in burnout begin at the beginning, that is to say, by establishing a reasoned, clinically-founded (differential) diagnosis for their entity of interest. As long as investigators do not complete the required groundwork for establishing a diagnosis and remain unable to distinguish a case of burnout from either a noncase or an existing disorder, conclusions regarding the prevalence of burnout will be nonsense. To close this comment, we note that an immediately available solution for effectively monitoring and protecting physicians’ occupational health …
