The Effect of Community-Level Socio-Economic Conditions on Threatening Racial Encounters

This paper contributes to the emerging literature on racial and ethnic tension by analyzing the relationship between local socio-economic conditions and the propensity for outsiders to have threatening racial encounters with insiders. We use unique data for a sample of active-duty Army personnel that allow us to first, link personnel to the local communities in which they are located and second, to avoid any selectivity bias associated with endogenous community selection. We find at best mixed evidence that racial hostility is related to economic vulnerability within a community and no evidence that racial conflict can be linked the level of public expenditure. Crime rates, however, are closely related to the incidence of threatening racial encounters and while a community’s demographic profile is also clearly linked to racial tension, these relationships cannot be easily generalized across minority groups or type of threatening racial encounter.racial and ethnic tension; U.S. military; economics of minorities

Do Non-Cognitive Skills Help Explain the Occupational Segregation of Young People?

This paper investigates the role of non-cognitive skills in the occupational segregation of young workers entering the U.S. labor market. We find entry into male-dominated fields of study and male-dominated occupations are both related to the extent to which individuals believe they are intelligent and have "male" traits while entry into male-dominated occupations is also related to the willingness to work hard, impulsivity, and the tendency to avoid problems. The nature of these relationships differs for men and women, however. Non-cognitive skills (intelligence and impulsivity) also influence movement into higher-paid occupations, but in ways that are similar for men and women. On balance, non-cognitive skills provide an important, though incomplete, explanation for segregation in the fields that young men and women study as well as in the occupations in which they are employed.non-cognitive skills, occupation, youth, gender

The Sexual Harassment of Female Active-Duty Personnel: Effects on Job Satisfaction and Intentions to Remain in the Military

This paper examines the relationship between sexual harassment and the job satisfaction and intended turnover of active-duty women in the U.S. military using unique data from a survey of the incidence of unwanted gender-related behavior conducted by the U.S. Department of Defense. Overall, 70.9 percent of active-duty women reported experiencing some type of sexually harassing behavior in the 12 months prior to the survey. Using single-equation probit models, we find that experiencing a sexually harassing behavior is associated with reduced job satisfaction and heightened intentions to leave the military. However, bivariate probit results indicate that failing to control for unobserved personality traits causes single-equation estimates of the effect of the sexually harassing behavior to be overstated. Similarly, including women’s views about whether or not they have in fact been sexually harassed directly into the single equation model reduces the estimated effect of the sexually harassing behavior itself on job satisfaction by almost a half while virtually eliminating it for intentions to leave the military. Finally, women who view their experiences as sexual harassment suffer additional negative consequences over and above those associated with the behavior itself.job satisfaction; sexual harassment; military employment

Racial and Ethnic Discrimination in Local Consumer Markets: Exploiting the Army’s Procedures for Matching Personnel to Duty Locations

We use the exogenous assignment of Army personnel to duty locations to analyze the relationship between the characteristics of local markets and the propensity for consumers to be subjected to racial discrimination in their everyday commercial transactions. Overall, one in ten soldiers report that they or their families have experienced racial discrimination in finding non-government housing or in patronizing businesses in their local communities. Discrimination is related to a community’s demographic profile with white and Asian soldiers feeling more unwelcome in local businesses as the local population becomes heavily weighted towards other groups. Moreover, there is evidence that increased economic vulnerability in the community results in more housing discrimination amongst minorities. While the evidence that increased competition reduces consumer market discrimination is mixed, it is clear that discrimination is related to the nature of a soldier’s interaction with the local community.Consumer Markets, discrimination, U.S. Military, Economics of Minorities

The Skills of Female Immigrants to Australia, Canada, and the United States

Census data for 1990/91 indicate that Australian and Canadian female immigrants appear to have higher levels of English fluency, education, and income (relative to natives) than do U.S. female immigrants. This skill deficit for U.S. female immigrants arises in large part because the United States receives a much larger share of immigrants from Latin America than do the other two countries. However, even among women originating outside Latin America, the proportion of foreign-born women in the United States who are fluent in English is much lower than among foreign-born women in Australia. Furthermore, immigrant/native education gaps are reduced but not eliminated by the exclusion of Latin American women from the analysis. In contrast, other evidence for men suggests that the gap in observed skills among male immigrants to the United States is completely eliminated when Latin American immigrants are excluded from the estimation sample (Borjas, 1993; Antecol, et al., 2001). The importance of national origin and the general consistency in the results for men (who are routinely subjected to the selection criteria of various immigration programs) and women (who are not) suggests that many factors other than immigration policy per se are at work in producing skill variation among these three immigration streams.

Combining technology with human resources management to strengthen virtual teams

Technology tools that best fit work tasks based on time and geography needs can encourage knowledge sharing, trust building and socialisation. Clark Shah-Nelson and Heather A. Johnson write that these tools, in combination with human resource management policies related to hiring, induction, training, and on-going appraisal practices can improve the performance of virtual teams

Obstetrician-assessed maternal health at pregnancy predicts offspring future health

Background: We aimed to examine the association between obstetrician assessment of maternal physical health at the time of pregnancy and offspring cardiovascular disease risk.<p></p> Methods and Principal Findings: We examined this association in a birth cohort of 11,106 individuals, with 245,000 person years of follow-up. We were concerned that any associations might be explained by residual confounding, particularly by family socioeconomic position. In order to explore this we used multivariable regression models in which we adjusted for a range of indicators of socioeconomic position and we explored the specificity of the association. Specificity of association was explored by examining associations with other health related outcomes. Maternal physical health was associated with cardiovascular disease: adjusted (socioeconomic position, complications of pregnancy, birthweight and childhood growth at mean age 5) hazard ratio comparing those described as having poor or very poor health at the time of pregnancy to those with good or very good health was 1.55 (95%CI: 1.05, 2.28) for coronary heart disease, 1.91 (95%CI: 0.99, 3.67) for stroke and 1.57 (95%CI: 1.13, 2.18) for either coronary heart disease or stroke. However, this association was not specific. There were strong associations for other outcomes that are known to be related to socioeconomic position (3.61 (95%CI: 1.04, 12.55) for lung cancer and 1.28 (95%CI:1.03, 1.58) for unintentional injury), but not for breast cancer (1.10 (95%CI:0.48, 2.53)).<p></p> Conclusions and Significance: These findings demonstrate that a simple assessment of physical health (based on the appearance of eyes, skin, hair and teeth) of mothers at the time of pregnancy is a strong indicator of the future health risk of their offspring for common conditions that are associated with poor socioeconomic position and unhealthy behaviours. They do not support a specific biological link between maternal health across her life course and future risk of cardiovascular disease in her offspring.<p></p&gt

Patient Perspectives on Osseointegration: A National Survey of Veterans with Upper Limb Amputation

INTRODUCTION: Osseointegrated (OI) prostheses have a unique benefit-risk profile among prosthetic alternatives and have been marketed in the United States under a Humanitarian Device Exemption since 2015. Information about upper limb prosthesis user perspectives on benefits and risks, prosthesis-user subpopulations for whom OI is most acceptable, and outcomes that matter most to patients could help inform clinical and regulatory decision-making. Recent 21st Century Cures legislation expanded the role of patient experience data in the decision-making process of the U.S. Food and Drug Administration, recognizing that patient perspectives may be informative to regulators. OBJECTIVE: To better understand prosthesis user perspectives about the benefits and risks associated with upper limb OI prostheses. DESIGN: Patient perspective survey. SETTING: Telephone administration. PARTICIPANTS: National sample of veterans with upper limb loss. INTERVENTIONS: NA MAIN OUTCOME MEASURES: Benefit-risk survey developed for this study. RESULTS: Twenty-eight percent of unilateral and 13% of bilateral amputees were willing to consider osseointegration surgery. Multivariate logistic regression models [OR; 95% CI] showed that transhumeral amputation level [OR 1.40; 1.01-1.98] was associated with greater willingness to consider surgery, whereas older age [OR 0.17; 0.09-0.32] and higher VR-12 Mental Component Summary [OR 0.53; 0.35-0.81] were associated with less willingness. Having a durable/reliable device, the ability to do more activities, and having a comfortable device were rated as very important or somewhat important by 98% or more for every risk condition. CONCLUSIONS: Persons who were older, had transradial amputation (compared to transhumeral), and those who had better mental functioning were less willing to consider this surgery. Respondents who were willing to consider surgery indicated that the most important potential benefits were obtaining a durable/reliable device, the ability to do more activities, and having a comfortable device. Most were willing to accept one or more risks of surgery, with long-term risks including chronic pain, loss of nerve function, or device failure considered the most unacceptable.

Fluorescent Nanoparticles for the Measurement of Ion Concentration in Biological Systems

Tightly regulated ion homeostasis throughout the body is necessary for the prevention of such debilitating states as dehydration.1 In contrast, rapid ion fluxes at the cellular level are required for initiating action potentials in excitable cells.2 Sodium regulation plays an important role in both of these cases; however, no method currently exists for continuously monitoring sodium levels in vivo3 and intracellular sodium probes 4 do not provide similar detailed results as calcium probes. In an effort to fill both of these voids, fluorescent nanosensors have been developed that can monitor sodium concentrations in vitro and in vivo.5,6 These sensors are based on ion-selective optode technology and consist of plasticized polymeric particles in which sodium specific recognition elements, pH-sensitive fluorophores, and additives are embedded.7-9 Mechanistically, the sodium recognition element extracts sodium into the sensor. 10 This extraction causes the pH-sensitive fluorophore to release a hydrogen ion to maintain charge neutrality within the sensor which causes a change in fluorescence. The sodium sensors are reversible and selective for sodium over potassium even at high intracellular concentrations.6 They are approximately 120 nm in diameter and are coated with polyethylene glycol to impart biocompatibility. Using microinjection techniques, the sensors can be delivered into the cytoplasm of cells where they have been shown to monitor the temporal and spatial sodium dynamics of beating cardiac myocytes.11 Additionally, they have also tracked real-time changes in sodium concentrations in vivo when injected subcutaneously into mice.3 Herein, we explain in detail and demonstrate the methodology for fabricating fluorescent sodium nanosensors and briefly demonstrate the biological applications our lab uses the nanosensors for: the microinjection of the sensors into cells; and the subcutaneous injection of the sensors into mice
