Gender Difference in Emotional and Behavioral Responses of Being Rendered Invisible

This study examined gender differences in emotional and behavioral responses to an experience of being invisible to others. Invisibility was defined as being ignored, slighted and overlooked by others. Participants recalled their own experience and answered questions about it and their responses on an anonymous web-based survey. Although such experiences could be very unpleasant, people may respond to such negative experiences very differently. It was hypothesized that in a patriarchal society like the United States in which men hold more power than women, that men would show emotion that was more aggressive such as anger, and respond more violently to incidents they were not respected. Women, on the other hand, were expected to be more subservient in their behavior and responses, show submissive emotions such as sadness, and respond less violently when they were not respected.

The Associations Between Social, Behavioral, and Health Risk Factors on a High School Student’s Decision to Pursue Post High School Plans

Background: Due to the relationship between SES and health, pursuing post high-school plans can lead to better future health outcomes for the student. The current paper assesses how behavioral and health risk factors, and family and social support, effect a student’s decision to pursue post high school plans. Methods: Data from the Youth Behavioral Component of the 2007 Connecticut School Health Survey were analyzed. Composite measures of exposure to/participation in violent behavior, mental and physical health, family/social support and substance abuse were created. The effects of these domains on the decision to pursue post high-school plans were assessed using logistic regression. Data were stratified by socioeconomic status. Results: Low SES students were more likely than high SES students to be doubtful for post high-school plans. Cocaine abuse emerged as the risk factor that put low SES students at the highest odds of not pursuing post high-school plans, followed by involvement in violent/aggressive behavior, and receiving less family/social support than their peers. Similar findings regarding violence and family/social support were found in the high SES group. Findings regarding substance abuse in the high SES group were not statistically significant. Discussion: Prevention programs regarding violence and substance abuse may have the added benefit of increasing the likelihood that high school students will make post high school plans. Preventing cocaine use among low SES students may be of particular importance. Violence prevention measures should be tailored to the target group. Adequate family/social support emerged as an encouraging factor for post high school plans.

Behavioral Profile of the Novel Cannabinoid Agonist AM4054

Although cannabinoid drugs have been used for thousands of years both recreationally and therapeutically, little has been known about their mechanisms of action until recently. Since the discovery of the endogenous cannabinoid CB1 receptor in 1988, the behavioral profile of cannabinoid receptor ligands has been much more thoroughly defined. Cannabinoid CB1 agonists have been shown to produce a variety of behavioral effects including suppression of locomotion, catalepsy, hypothermia, and analgesia. Research has also demonstrated that these behavioral effects can be inhibited by CB1 receptor antagonists including SR 141716 and AM 251. Although behavioral indicators of anxiety including thigmotaxis have been observed in several different paradigms, there is inconclusive and often times contradictory evidence to define the role of anxiety in CB1 receptor activation. The present study addressed the behavioral profile of AM 4054, a novel full agonist at the CB1 receptor, as well as the ability of the CB1 antagonist AM 251 to reverse these effects. To further identify and expand research on the suppression of locomotion and induction of thigmotaxis with the administration of a CB1 agonist, experiment 1 was conducted in the open field. In this experiment, each rat (n=40) was randomly assigned one of the five treatments: vehicle, 0.16, 0.32, 0.64, or 1.25 mg/kg AM 4054. After a 30 minute pre-treatment, each subject was tested in the open field for 18 minutes. Results indicated that AM 4054 produced a dose-related suppression of locomotion as well as the subtle presence of thigmotaxis in two out of four doses. In experiment 2, subjects (n=40) received either vehicle or 2.0 or 4.0 mg/kg AM 251 60 minutes prior to testing. After 30 minutes, the subjects were given either a 0.3 mg/kg dose of AM 4054 or vehicle. After a total pretreatment duration of 60 minutes, the animals were tested on a battery of tasks including an 18 minute session in locomotor boxes. Experiment 2 was a continuation of a previous study conducted in the same lab, which confirmed the effects of AM 4054 on this tetrad of tasks as being consistent with other cannabinoid agonists. In this experiment the effects of AM 4054 were reversed by the administration of the CB1 antagonist AM 251. Past studies have shown that AM 4054 is a highly potent drug with behavioral actions similar to other cannabinoid CB1 agonists. Furthermore, AM 4054 can be a useful drug in future studies, and has potential therapeutic value for the treatment of various conditions.

RELATIONS AMONG REMEMBERED PARENTAL ACCEPTANCE AND BEHAVIORAL CONTROL IN CHILDHOOD, ADULTS' CURRENT PSYCHOLOGICAL ADJUSTMENT, AND CAREER INDECISIVENESS

This study tested the hypothesis that career indecisiveness among men tends to be associated with different levels of self-reported psychological adjustment and with different remembrances of parental (maternal and paternal) acceptance and behavioral control in childhood from those of women. One hundred twenty-six respondents ages 17 through 54 (M = 23.7 years, SD = 8.21 years) participated in this study. Thirty-seven where males; 90 were females. Measures used in this study included the Career Decision Scale, the Adult version of the Parental Acceptance-Rejection/Control Questionnaire for mothers and for fathers, and the Adult version of the Personality Assessment Questionnaire. Both men and women remembered their mothers as well as their fathers as being loving in childhood. Additionally, men and women remembered both parents as being moderately behaviorally controlling in childhood. Finally, both men and women reported a fair level of psychological maladjustment. And on average, both men and women were fairly indecisive about their careers. Results of analyses supported the hypothesis in that career indecisiveness among women but not men was significantly correlated with remembered maternal and paternal acceptance in childhood, as well as with self-reported psychological adjustment and age. However, only women’s self-reported psychological adjustment made a significant and unique contribution to variations in their reports of career indecisiveness. None of the predictor variables were significantly associated with career indecisiveness among men.

Social and behavioral determinants of consistent condom use among female commercial sex workers (FCSWs) in Ghana

This study aims at investigating the social and behavioral predictors of consistent condom use among female commercial sex workers (FCSWs) in Ghana. Street commercial sex workers were interviewed in Accra, Kumasi and Techiman. Whereas respondents had attained certain accurate knowledge about HIV transmission routes, misconceptions were still commonly reported. The level of condom education was very low (14%), however consistent condom use (all the time) with clients was relatively high (49.6%), 38.89% reported using condom sometimes and 11.56% reported never using condoms. ^ 277 of the respondent ants did not use condoms all the time. 163 of them reported not using condoms due to refusal by their clients, the remaining 64 respondents did not even request their clients to use condom due to cultural perception of power, lack of authority and the fear of loosing clients. ^ Significant predictive factors associated with consistency of condom use among FCSWs in a multivariate analysis were; age, level of education, religion, and number of customers. Some of the major obstacles to condom use by the FCSWs were refusal by clients, availability of free condoms, trying to communicate trust to their clients, and the lack of empowerment to negotiate safer sex with clients. Some of the respondents may have developed a false sense of safety by subjectively assessing whether their clients were well and do not look sick, but they were unaware that HIV carriers may show no obvious symptoms of illness at all. ^ In summary, this study points to an urgent need for reestablishing effective prevention intervention and some insights of what is required of such program in Ghana. ^

Studies on behavioral regulations of morphine tolerance in rats

Opioids remain the drugs of choice in chronic pain treatment, but opioid tolerance, defined as a decrease in analgesic effect after prolonged or repeated use, dramatically limits their clinical utility. Opioid tolerance has classically been studied by implanting spinal catheters in animals for drug administration. This procedure has significant morbidity and mortality, as well as causing an inflammatory response which decreases the potency of opioid analgesia and possibly affects tolerance development. Therefore, we developed and validated a new method, intermittent lumbar puncture (Dautzenberg et al.), for the study of opioid analgesia and tolerance. Using this method, opioid tolerance was reliably induced without detectable morbidity. The dose of morphine needed to induce analgesia and tolerance using this method was about 100-fold lower than that required when using an intrathecal catheter. Only slight inflammation was found at the injection site, dissipated within seven mm. ^ DAMGO, an opioid μ receptor agonist, has been reported to inhibit morphine tolerance, but results from different studies are inconclusive. We evaluated the effect of DAMGO on morphine tolerance using our newly-developed ILP method, as well as other intrathecal catheter paradigms. We found that co-administration of sub-analgesic DAMGO with morphine using ILP did not inhibit morphine tolerance, but instead blocked the analgesic effects of morphine. Tolerance to morphine still developed. Tolerance to morphine can only be blocked by sub-analgesic dose of DAMGO when administered in a lumbar catheter, but not in cervical catheter settings. ^ Finally, we evaluated the effects of Gabapentin (GBP) on analgesia and morphine tolerance. We demonstrated that GBP enhanced analgesia mediated by both subanalgesic and analgesic doses of morphine although GBP itself was not analgesic. GBP increased potency and efficacy of morphine. GBP inhibited the expression, but not the development, of morphine tolerance. GBP blocked tolerance to analgesic morphine but not to subanalgesic morphine. GBP reversed the expression of morphine tolerance even after tolerance was established. These studies may begin to provide new insights into mechanisms of morphine tolerance development and improve clinical chronic pain management. ^

Behavioral cognitions and factors related to hepatitis B vaccine acceptance and compliance in a cohort of drug users in Houston, Texas

Purpose. Drug users are a large group of those at highest risk for contracting Hepatitis B (HBV). This study sought to identify predictors of HBV vaccine acceptance and compliance in a cohort of current drug users in Houston, Texas. Perceived severity of HBV, perceived risk of HBV, perceived peer support of HBV vaccine, and perceived benefits of HBV vaccine were also examined assess their relationship to HBV compliance. ^ Methods. A randomized intervention study was conducted in a cohort of current drug users in Houston, Texas. Participants were recruited by community outreach workers from two urban neighborhoods in Houston known for high drug use. Participants were randomized to a standard vaccine schedule group or an accelerated vaccine schedule group. Participants were also randomized to either a standard behavioral intervention group or an enhanced behavioral intervention group designed to increase HBV vaccine acceptance and compliance. Baseline visits included an interview for demographic factors, drug and sexual behaviors, and HBV beliefs; and participants received the first dose of the HBV vaccine and one of the behavioral interventions. ^ Results. Of 1,643 screening participants, 77% accepted the HBV vaccine. Participants ages ≥50 were twice as likely to accept the vaccine. African Americans and less frequent drug users were also significantly more likely to accept the vaccine. Of the 1,259 participants who enrolled in the study, 75% were compliant to the HBV vaccine. Predictors of compliance were found to be race, housing status, and alcohol use. Speedball users were found to be 74% less likely to be compliant the HBV vaccine. None of the behavioral constructs assessed were found to significantly predict HBV compliance. However, additional analyses found that there were significant changes in mean scores of the behavioral concepts when measured at six month follow-up. ^ Conclusion. Results from this study indicate that when offered a free vaccine in the drug user community, a large percentage will be compliant to the vaccine series. The behavioral cognitions commonly used in HBV compliance research need to be extended to accurately fit this cohort. Also, vaccine intervention focus needs to be on reaching the homeless segment of the drug users and the speedball users. ^

Examination of the influence of behavioral, normative and control beliefs on the adherence to a prescribed renal diet among elderly populations with chronic to end-stage renal disease

The 1999-2004 prevalence of chronic kidney disease in adults 20 year or older (15.5 million) is an estimated 7.69%. The risk of developing CKD is exacerbated by diabetes, hypertension and/or a family history of kidney disease. African Americans, Hispanics, Pacific Islanders, Native Americans, and the elderly are more susceptible to higher incidence of CKD. The challenges of aging coupled with co-morbidities such as kidney disease raises the potential for malnutrition among elderly (for the purpose of this study 55 years or older) populations. Lack of adherence to prescribed nutrition guidelines specific to renal failure jeopardizes body homeostasis and increases the likelihood of future morbidity and resultant mortality. The relationship and synergy that exists between diet and disease is evident. Clinical experience with renal patients has indicated the importance of adherence to diet therapy specific to kidney disease. Extension investigation of diet adherence among endstage renal disease patients revealed a sizeable dearth in the current literature. This thesis study was undertaken to help reduce that void. The study design is qualitative and descriptive. Support, cooperation, and collaboration were provided by the University of Texas Nephrology Department, University of Texas Physicians, and DaVita Dialysis Centers. Approximately 105 male and female chronic to end-stage kidney disease patients were approached to participate in elicitation interviews in dialysis treatment facilities regarding their present diet beliefs and practices. Eighty-five were recruited and agreed to participate. Inclusion criteria required individuals to be between 35-90 years of age; capable of completing a 5-10 minute interview; and English speaking. Each kidney patient was asked seven (7) non-leading questions developed from the constructs of the Theory of Planned Behavior. The study presents a descriptive comparison of behavioral, normative, and control beliefs that influence adherence to renal diets by age, race, and gender. The study successfully concluded that behavioral, normative, and control beliefs of chronic to end-stage renal patients promoted execution and adherence to prescribed nutrition. This study provides valuable information for dietitians, technicians, nurses, and physicians to assess patient compliance toward prescribed nutrition and the means to support or improve that performance. ^

Organization of the inferotemporal cortex in the macaque monkey: Connections of areas PITv and CITvp

Visual cortex of macaque monkeys consists of a large number of cortical areas that span the occipital, parietal, temporal, and frontal lobes and occupy more than half of cortical surface. Although considerable progress has been made in understanding the contributions of many occipital areas to visual perceptual processing, much less is known concerning the specific functional contributions of higher areas in the temporal and frontal lobes. Previous behavioral and electrophysiological investigations have demonstrated that the inferotemporal cortex (IT) is essential to the animal's ability to recognize and remember visual objects. While it is generally recognized that IT consists of a number of anatomically and functionally distinct visual-processing areas, there remains considerable controversy concerning the precise number, size, and location of these areas. Therefore, the precise delineation of the cortical subdivisions of inferotemporal cortex is critical for any significant progress in the understanding of the specific contributions of inferotemporal areas to visual processing. In this study, anterograde and/or retrograde neuroanatomical tracers were injected into two visual areas in the ventral posterior and central portions of IT (areas PITv and CITvp) to elucidate the corticocortical connections of these areas with well known areas of occipital cortex and with less well understood regions of inferotemporal cortex. The locations of injection sites and the delineation of the borders of many occipital areas were aided by the pattern of interhemispheric connections, revealed following callosal transection and subsequent labeling with HRP. The resultant patterns of connections were represented on two-dimensional computational (CARET) and manual cortical maps and the laminar characteristics and density of the projection fields were quantified. The laminar and density features of these corticocortical connections demonstrate thirteen anatomically distinct subdivisions or areas distributed within the superior temporal sulcus and across the inferotemporal gyrus. These results serve to refine previous descriptions of inferotemporal areas, validate recently identified areas, and provide a new description of the hierarchical relationships among occipitotemporal cortical areas in macaques. ^

Behavioral journalism newsletters to increase employee participation in a free worksite wellness center

Background. Providing an worksite fitness center for employees is an effective setting to increase an adult’s levels of physical activity, demonstrably reducing health care costs and elevating employee productivity. Increasing compliance and adherence among employees to consistently utilize an onsite facility remains a challenge.^ Purpose. To illustrate if two electronic behavioral journalism newsletters can increase employee participation in a free worksite wellness center.^ Design. A randomized control trial was implemented. ^ Setting. A large petroleum-producing corporation located in Houston, Texas Subjects.70 full or part time employees that had checked into visited the wellness center during September, October, and November 2009. ^ Intervention. Two behavioral journalism newsletters were created based on authentic community member role model interviews. Newsletters were distributed to intervention group participants via company email. Intervention and control group participant’s visits to the wellness center were monitored via a key card check in system at the facility for two weeks following the newsletter intervention.^ Analysis. Count variable statistics were used to identify rate differences between the intervention and control group wellness center visits. A binomial test for equality of proportions was used to identify differences between participants that had at least one visit to the wellness center compared with those with none.^ Results. Both intervention and control groups had a baseline of zero wellness center visits. The control group had a mean visit rate 0.441 and the intervention group had 0.857. A 0.416, almost one half more visits were found among the intervention group.^ Conclusion. This study indicates that behavioral journalism newsletters featuring a role model from within the worksite population can be a cost effective communication method to improve participation in an onsite wellness center. ^

Behavioral risk profile of marathon runners

Although long distance running clearly has benefits--as witnessed by its popularity--it also has risks of injury and death. Little is known, however, about the prevalence of potentially dangerous training habits in long distance runners, although anecdotal information suggests that many runners have erroneous beliefs about risks and benefits of marathon running. We conducted a cross-sectional survey to estimate the prevalence of 19 potentially dangerous training habits (risky behaviors) among marathon runners. A 66-item self-administered questionnaire was mailed to a stratified random sample of runners who finished of the 1992 Houston-Tenneco Marathon and were 21-71 years of age. Responses were obtained from 508 runners (83%) with approximately equal representation in four age-gender groups: men $<$40 years, men $\ge$40 years, women $<$40 years, and women $\ge$40 years.^ Prevalences of risky behaviors were high. 50% or more ran in dangerously hot and humid conditions, did not cool down or stretch after running, did not wear proper running gear, or ran when injured or ill; 25-49% did not warm up, ran on dangerous surfaces, did not drink sufficient water during training, increased weekly mileage too quickly, and ran during lightning storms; 10-24% ran daily, ran in areas with high pollution, ran in the same direction as traffic, did hard runs frequently, ran more than 60 miles per week, or ran against the advice of a physician.^ Positive associations were found between the practice of risky behaviors and self-reported prevalence of musculoskeletal injuries, heat-related injuries, noncompliance with recommendations for preventive health examinations, and noncompliance with positive health habits.^ These results indicate that many marathon runners engage in training habits that may increase risk of substantial injury or illness. Further studies are needed to explore the association of risky training behaviors on the incidence of injuries, and to determine reasons for noncompliance with recommendations from sports medicine specialists. ^
