Mariner Mars 1971 inertial reference unit

The design concept of an inertial reference unit is reported that uses the gyroscope in a rate mode in conjunction with a unique application of a drift compensated and temperature stabilized solid state integrator for the inertial mode. A typical test program and results for an inertial reference unit as applied to the Mariner Mars 1971 program to achieve highly reliable spacecraft operation are also described

Institutional Investors, Corporate Ownership, and Corporate Governance: Global Perspectives

Institutional Investors and Executive Compensation

Due to institutional investors' increasing ownership and interest in corporate governance, we hypothesize that the presence of institutional investors is associated with certain executive compensation structures. We find a significantly negative relation between the level of compensation and the concentration of institutional ownership, suggesting that institutions serve a monitoring role in the shareholder-manager agency problem. We further find a significantly positive relation between the pay-for-performance sensitivity of executive compensation and both the level and concentration of institutional ownership. These results suggest that the institutions act as a complement rather than a substitute to incentive compensation in mitigating the agency problem

The importance of climate risks for institutional investors

According to our survey about climate risk perceptions, institutional investors believe climate risks have financial implications for their portfolio firms and that these risks, particularly regulatory risks, already have begun to materialize. Many of the investors, especially the long-term, larger, and ESG-oriented ones, consider risk management and engagement, rather than divestment, to be the better approach for addressing climate risks. Although surveyed investors believe that some equity valuations do not fully reflect climate risks, their perceived overvaluations are not large

Severe multidirectional instability of the gleno-humeral joint

The article presents a case study of a 22 year-old female college athlete with multidirectional instability (MDI) of the glen-humeral (GH) joint. The athlete participated in overhead sports activities such as softball, basketball and swimming, and her presenting symptoms included decreased function, crepitus and spontaneous subluxation. Clinical management and range of motion (ROM) measurement are also discussed

Project EMPOWER: An Innovative Approach to Community Behavioral Health Service Delivery

Project EMPOWER was a grant funded initiative designed to positively impact a rural community by providing behavioral health services and case management to low-income families. An interdisciplinary service team comprised of behavioral health specialists and graduate level interns in the fields of social work, psychiatric nursing, and counseling worked to provide services under the supervision of a doctorate level clinical social work professor. Community partnerships were forged to increase opportunities for community members to have accessible, affordable services. Using an empowerment model rooted in systems and integrated practice, the services included assessments, referrals, group, individual and family counseling, child care, and psychoeducational workshops

Religious Identity, Religious Attendance, and Parental Control

Using a national sample of adolescents aged 10–18 years and their parents (N = 5,117), this article examines whether parental religious identity and religious participation are associated with the ways in which parents control their children. We hypothesize that both religious orthodoxy and weekly religious attendance are related to heightened levels of three elements of parental control: monitoring activities, normative regulations, and network closure. Results indicate that an orthodox religious identity for Catholic and Protestant parents and higher levels of religious attendance for parents as a whole are associated with increases in monitoring activities and normative regulations of American adolescents

ESG Shareholder Engagement and Downside Risk

We show that engagement on environmental, social, and governance issues can benefit shareholders by reducing firms’ downside risks. We find that the risk reductions (measured using value at risk and lower partial moments) vary across engagement types and success rates. Engagement is most effective in lowering downside risk when addressing environmental topics (primarily climate change). Further, targets with large downside risk reductions exhibit a decrease in environmental incidents after the engagement. We estimate that the value at risk of engagement targets decreases by 9% of the standard deviation after successful engagements, relative to control firms

Organic Solvent Exposure and Depressive Symptoms Among Licensed Pesticide Applicators in the Agricultural Health Study

Purpose Although organic solvents are often used in agricultural operations, neurotoxic effects of solvent exposure have not been extensively studied among farmers. The current analysis examined associations between questionnaire-based metrics of organic solvent exposure and depressive symptoms among farmers. Methods Results from 692 male Agricultural Health Study participants were analyzed. Solvent type and exposure duration were assessed by questionnaire. An “ever-use” variable and years of use categories were constructed for exposure to gasoline, paint/lacquer thinner, petroleum distillates, and any solvent. Depressive symptoms were ascertained with the Center for Epidemiologic Studies Depression Scale (CES-D); scores were analyzed separately as continuous (0–60) and dichotomous (≥16) variables. Multivariate linear and logistic regression models were used to estimate crude and adjusted associations between measures of solvent exposure and CES-D score. Results Forty-one percent of the sample reported some solvent exposure. The mean CES-D score was 6.5 (SD 6.4; median 5; range 0–44); 92% of the sample had a score below 16. After adjusting for covariates, statistically significant associations were observed between ever-use of any solvent, long duration of any solvent exposure, ever-use of gasoline, ever-use of petroleum distillates, and short duration of petroleum distillate exposure and continuous CES-D score (p \u3c 0.05). Although nearly all associations were positive, fewer statistically significant associations were observed between metrics of solvent exposure and the dichotomized CES-D variable. Conclusions Solvent exposures were associated with depressive symptoms among farmers. Efforts to limit exposure to organic solvents may reduce the risk of depressive symptoms among farmers
