Beyond students: how teacher psychology shapes educational inequality.

Although researchers investigating psychological contributors to educational inequality have traditionally focused on students, a growing literature highlights the importance of teachers' psychology in shaping disparities in students' educational achievement and attainment. In this review, we discuss recent advances linking teachers' attitudes, perceptions, and beliefs to inequality in students' outcomes. First, we identify specific aspects of teacher psychology that contribute to educational disparities, including teachers' biases, perceptions and expectations of students, beliefs about the nature of ability, and beliefs about group differences. Second, we synthesize mechanisms underlying the effects of teacher psychology on educational inequality, including teachers' disparate assessment of students' work and abilities, interpersonal interaction with students, and psychological impact on students. Implications for future research and interventions are discussed.

How university diversity rationales inform student preferences and outcomes.

It is currently commonplace for institutions of higher education to proclaim to embrace diversity and inclusion. Though there are numerous rationales available for doing so, US Supreme Court decisions have consistently favored rationales which assert that diversity provides compelling educational benefits and is thus instrumentally useful. Our research is a quantitative/experimental effort to examine how such instrumental rationales comport with the preferences of White and Black Americans, specifically contrasting them with previously dominant moral rationales that embrace diversity as a matter of intrinsic values (e.g., justice). Furthermore, we investigate the prevalence of instrumental diversity rationales in the American higher education landscape and the degree to which they correspond with educational outcomes. Across six experiments, we showed that instrumental rationales correspond to the preferences of White (but not Black) Americans, and both parents and admissions staff expect Black students to fare worse at universities that endorse them. We coded university websites and surveyed admissions staff to determine that, nevertheless, instrumental diversity rationales are more prevalent than moral ones are and that they are indeed associated with increasing White-Black graduation disparities, particularly among universities with low levels of moral rationale use. These findings indicate that the most common rationale for supporting diversity in American higher education accords with the preferences of, and better relative outcomes for, White Americans over low-status racial minorities. The rationales behind universities' embrace of diversity have nonlegal consequences that should be considered in institutional decision making.

An integrated WRF/HYSPLIT modeling approach for the assessment of PM(2.5) source regions over the Mississippi Gulf Coast region.

Fine particulate matter (PM(2.5)) is majorly formed by precursor gases, such as sulfur dioxide (SO(2)) and nitrogen oxides (NO(x)), which are emitted largely from intense industrial operations and transportation activities. PM(2.5) has been shown to affect respiratory health in humans. Evaluation of source regions and assessment of emission source contributions in the Gulf Coast region of the USA will be useful for the development of PM(2.5) regulatory and mitigation strategies. In the present study, the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model driven by the Weather Research & Forecasting (WRF) model is used to identify the emission source locations and transportation trends. Meteorological observations as well as PM(2.5) sulfate and nitric acid concentrations were collected at two sites during the Mississippi Coastal Atmospheric Dispersion Study, a summer 2009 field experiment along the Mississippi Gulf Coast. Meteorological fields during the campaign were simulated using WRF with three nested domains of 36, 12, and 4 km horizontal resolutions and 43 vertical levels and validated with North American Mesoscale Analysis. The HYSPLIT model was integrated with meteorological fields derived from the WRF model to identify the source locations using backward trajectory analysis. The backward trajectories for a 24-h period were plotted at 1-h intervals starting from two observation locations to identify probable sources. The back trajectories distinctly indicated the sources to be in the direction between south and west, thus to have origin from local Mississippi, neighboring Louisiana state, and Gulf of Mexico. Out of the eight power plants located within the radius of 300 km of the two monitoring sites examined as sources, only Watson, Cajun, and Morrow power plants fall in the path of the derived back trajectories. Forward dispersions patterns computed using HYSPLIT were plotted from each of these source locations using the hourly mean emission concentrations as computed from past annual emission strength data to assess extent of their contribution. An assessment of the relative contributions from the eight sources reveal that only Cajun and Morrow power plants contribute to the observations at the Wiggins Airport to a certain extent while none of the eight power plants contribute to the observations at Harrison Central High School. As these observations represent a moderate event with daily average values of 5-8 µg m(-3) for sulfate and 1-3 µg m(-3) for HNO(3) with differences between the two spatially varied sites, the local sources may also be significant contributors for the observed values of PM(2.5).

Inequality is a relationship.

A view of inequality as a relationship between the advantaged and the disadvantaged has gained considerable currency in psychological research. However, the implications of this view for theories and interventions designed to reduce inequality remain largely unexplored. Drawing on the literature on close relationships, we identify several key features that a relational theory of social change should include.

Epidemiology and cost of ventral hernia repair: making the case for hernia research.

PURPOSE: Ventral hernia repair (VHR) lacks standardization of care and exhibits variation in delivery. Complications of VHR, notably recurrence and infection, increase costs. Efforts at obtaining federal funding for VHR research are frequently unsuccessful, in part due to misperceptions that VHR is not a clinical challenge and has minimal impact on healthcare resources. We analyzed national trends for VHR performance and associated costs to demonstrate potential savings resulting from an improvement in outcomes. METHODS: Inpatient non-federal discharges for VHR were identified from the 2001-2006 Healthcare Cost and Utilization Project, supplemented by the Center for Disease Control 2006 National Survey of Ambulatory Surgery for outpatient estimates. The total number of VHRs performed in the US was estimated along with associated costs. Costs were standardized to 2010 US dollars using the Consumer Price Index and reported as mean with 95% confidence intervals (95% CI). RESULTS: The number of inpatient VHRs increased from 126,548 in 2001 to 154,278 in 2006. Including 193,543 outpatient operations, an estimated 348,000 VHRs were performed for 2006. Inpatient costs consistently rose with 2006 costs estimated at US $15,899 (95% CI $15,394-$16,404) per operation. Estimated cost for outpatient VHR was US $3,873 (95% CI $2,788-$4,958). The total cost of VHR for 2006 was US $3.2 billion. CONCLUSIONS: VHRs continue to rise in incidence and cost. By reducing recurrence rate alone, a cost saving of US $32 million dollars for each 1% reduction in operations would result. Further research is necessary for improved understanding of ventral hernia etiology and treatment and is critical to cost effective healthcare.

Interracial roommate relationships: negotiating daily interactions.

Jobs, social group memberships, or living arrangements lead many people to interact every day with another person from a different racial background. Given that research has shown that interracial interactions are often stressful, it is important to know how these daily interactions unfold across time and what factors contribute to the success or failure of these interactions. Both members of same-race and mixed-race college roommate pairs completed daily questionnaires measuring their emotional experiences and their perceptions of their roommate. Results revealed that roommates in mixed-race dyads experienced less positive emotions and intimacy toward their roommates than did roommates in same-race dyads and that the experience of positive emotions declined over time for ethnic minority students with White roommates. Mediation analyses showed that the negative effects of roommate race were mediated by the level of intimacy-building behaviors performed by the roommate. Implications for future research and university policies are discussed.

Disparities and distrust: the implications of psychological processes for understanding racial disparities in health and health care.

This paper explores the role of racial bias toward Blacks in interracial relations, and in racial disparities in health care in the United States. Our analyses of these issues focuses primarily on studies of prejudice published in the past 10 years and on health disparity research published since the report of the US Institute of Medicine (IOM) Panel on Racial and Ethnic Disparities in Health Care in 2003. Recent social psychological research reveals that racial biases occur implicitly, without intention or awareness, as well as explicitly, and these implicit biases have implications for understanding how interracial interactions frequently produce mistrust. We further illustrate how this perspective can illuminate and integrate findings from research on disparities and biases in health care, addressing the orientations of both providers and patients. We conclude by considering future directions for research and intervention.

Cognitive costs of exposure to racial prejudice.

This study examined how encountering racial prejudice affects cognitive functioning. We assessed performance on the Stroop task after subjects reviewed job files that suggested an evaluator had made nonprejudiced, ambiguously prejudiced, or blatantly prejudiced hiring recommendations. The cognitive impact of exposure to ambiguous versus blatant cues to prejudice depended on subjects' racial group. Black subjects experienced the greatest impairment when they saw ambiguous evidence of prejudice, whereas White subjects experienced the greatest impairment when they saw blatant evidence of prejudice. Given the often ambiguous nature of contemporary expressions of prejudice, these results have important implications for the performance of ethnic minorities across many domains.

Intergroup contact and pluralistic ignorance.

The present work examined the relationship between people's own interpretations of why they avoid intergroup contact and their interpretations of why out-groups avoid intergroup contact. Studies 1 and 2 demonstrate that Whites and Blacks would like to have more contact with the out-group but believe the out-group does not want to have contact with them. Studies 3-5 show that Whites and Blacks make divergent explanations about their own and their potential out-group partner's failure to initiate contact. Specifically, individuals explained their own inaction in terms of their fear of being rejected because of their race but attributed the out-group members' inaction to their lack of interest. Study 6 examined the behavioral consequences of this self-other bias. Finally, Study 7 applied theoretical work on the extended contact hypothesis to explore a means to reduce this self- other bias. The implications of these studies for improving intergroup interactions are discussed.

Medical barriers to access to family planning.

PIP: Medical barriers to family planning (FP) are identified as contraindications, eligibility, process hurdles, the provider of contraception, provider bias, and regulation. These obstacles to FP are considered practices which may have a medical rationale in some manner but are scientifically unjustified. The denial or interference in obtaining contraception is unacceptable. Examples are given of barriers, i.e., eligibility criteria such as lack of headaches or history of diabetes. Obstacles that deter oral contraception (OC) are a by-product of testing requirements, repeat visits, and long waits. OC provision does not require a physician's prescription; a trained technician can perform similar functions. When a provider such as community-based distributor is limited in provision of methods, women are not given the right to choose from a full menu. Medical barriers occur due to the ignorance about the safety of contraceptives, the benefits of FP, and the role of health professionals in service delivery. Clinics tend to be curative rather than preventive. In place of careful thinking, there are rules in a hierarchical medical system suitable for treatment of complicated life-threatening illness. Barriers are complicated, interrelated, and situational. The solutions suggested are 1) informing the health community and mobilizing medical leadership, 2) defining and treating the FP seeker as a client and not a medical patient, and 3) engaging in more epidemiological research to assess the risk/benefits of contraceptive use and operations research to evaluate ways to reduce medical restrictions. The position that obstacles are an example of quality of care does not support the Bruce-Jain FP quality of care framework. Health and FP services may be integrated but contraceptive usage should not be at the expense of health care. The obstacles are not just in developing countries where it would appear that access to FP far outweighs the risks of maternal mortality from pregnancy. Providers are not the target is creating a win-win-win situation for the client, the provider, and organized public health.^ieng

Unhealthy health care costs.

The private sector has implemented many cost containment measures in efforts to control rising health care costs. However, these measures have not controlled costs in the long run, and can be expected not to succeed as long as business cannot control factors within the health care system which affect costs. Controlling private sector health care costs requires constraints on cost shifting which necessitates a unified financing system with expenditure limits. A unified financing system will involve a partnership between the public and private sectors.

Prospects for the use of embryos in the control of disease and the transport of genotypes.

Transfer and low temperature storage of embryos are now proven techniques for a number of mammalian species. These techniques are useful in control of disease and in saving genotypes from infected animals. The place of embryos in the epidemiology of disease depends upon whether the causative organism can gain entry to the oocyte before or at fertilisation and on whether the young embryo can be invaded by organisms in the uterine environment. There is little evidence that important live-stock diseases are transmitted via gametes. The zona pellucida surrounding the embryo is an effective barrier against a number of important disease organisms; in some cases the embryo is susceptible once it has hatched from the zona pellucida. It is important therefore in considering the use of embryos in disease control, to ensure that virus is not attached to the surface of the zona pellucida from where it can infect the recipient and/or the embryo after hatching. Washing procedures have been devised together with the use of enzymes and antisera to remove virus from the surface of embryos. Some viruses enter pores and sperm tracks in the zona and removal of these may present a problem. African swine fever virus has been shown to resist removal by treatment with enzymes. There are no guidelines as to the likely interaction between a certain virus and embryos. Therefore each virus of interest must be tested to determine whether it can be transmitted via washed embryos. Nevertheless there are numerous instances of the use of embryo transfer to eradicate a specific disease or to save valuable genetic material from infected animals without transmitting disease.
