Re-analysis of a banding study to test the effects of an experimental increase in bag limits of mourning doves

In 1966-1971, eastern US states with hunting seasons on mourning doves ( Zenaida macroura ) participated in a study designed to estimate the effects of bag limit increases on population survival rates. More than 400 000 adult and juvenile birds were banded and released during this period, and subsequent harvest and return of bands, together with total harvest estimates from mail and telephone surveys of hunters, provided the database for analysis. The original analysis used an ANOVA framework, and resulted in inferences of no effect of bag limit increase on population parameters (Hayne 1975). We used a logistic regression analysis to infer that the bag limit increase did not cause a biologically significant increase in harvest rate and thus the experiment could not provide any insight into the relationship between harvest and annual survival rates. Harvest rate estimates of breeding populations from geographical subregions were used as covariates in a Program MARK analysis and revealed an association between annual survival and harvest rates, although this relationship is potentially confounded by a latitudinal gradient in survival rates of dove populations. We discuss methodological problems encountered in the analysis of these data, and provide recommendations for future studies of the relationship between harvest and annual survival rates of mourning dove populations.     

Internationalizing managers: Speeding up the process

Most multinational companies agree that their managers need international expertise; but a recent survey surprisingly revealed that more than half of the large European corporations participating in the study lacked a strategy — either in writing or as a commonly articulated value — for internationalizing their managers (Price Waterhouse/Cranfield, 1991, p. 14). Not only must cutting-edge companies implement this process, but they have to find ways to speed it up to stay competitive.Brooklyn Derr and Gary Oddou report a 1991 survey conducted with 105 European multinationals employing an average of 30,000 workers each. The respondents, usually directors of human resource management and management development, identified the current strategies most frequently used to internationalize their firms, the importance assigned these strategies (not necessarily the same thing), and short-range trends. The article also explores the different challenges presented by attempting to internationalize senior managers as compared to junior managers.Expatriation/repatriation has been the traditional means of internationalizing managers, but companies are not doing a uniformly able job in preparing their managers for expatriation nor in taking advantage of their expertise after they return. In addition to making recommendations about expatriation/repatriation, the authors suggest newer, faster practices for internationalizing managers.

Addressing the impact of trauma before diagnosing mental illness in child welfare

Congress set requirements for child welfare agencies to respond to emotional trauma associated with child maltreatment and removal. In meeting these requirements, agencies should develop policies that address child trauma. To assist in policy development, this study analyzes more than 14,000 clinical assessments from child welfare in Illinois. Based on the analysis, the study recommends child welfare agencies adopt policies requiring that (1) mental health screenings and assessments of all youth in child welfare include measures of traumatic events and trauma-related symptoms; (2) evidence-based, trauma-focused treatment begin when a youth in child welfare demonstrates a trauma-related symptom; and (3) a clinician not diagnose a youth in child welfare with a mental illness without first addressing the impact of trauma. The study also raises the issue of treatment reimbursement based on diagnosis.     

Secondary traumatic stress and burnout in child welfare workers: a comparative analysis of occupational distress across professional groups

This study describes predictors of secondary traumatic stress and burnout in a national sample of helping professionals, with a specific focus on the unique responses of child welfare (CW) workers. Specific worker and exposure characteristics are examined as possible predictors of these forms of occupational distress in a sample of 669 professionals from across the country who responded to mailed (e-mail and post) invitations to participate in an online survey. E-mail and home mailing addresses were secured from licensure boards and professional membership organizations in six states from across the country that had high rates of child related deaths in 2009. Respondents completed the Professional Quality of Life IV (Stamm, 2005) to ascertain compassion fatigue (CF) and burnout symptoms. Being male, young, Hispanic, holding rural residence, and endorsing a lack of religious participation were significant predictors of secondary traumatic stress. Similarly, being male and young predicted high burnout rates, while actively participating in religious services predicted lower burnout. CW worker job status as a professional was significantly more likely to predict CF and burnout compared to all other types of behavioral healthcare professionals. Based on the findings from this study, this paper proposes strategies for enhancing self-care for CW workers, and describes the essential elements of a trauma-informed CW agency that addresses secondary traumatic stress and burnout.     

Treatment of late-life mental disorders in primary care: we can do a better job

Health care services provided to older adults today are not as effective as they should be. The quality of care for late-life mental disorders often falls short of desired standards. The growth of the elderly population makes it imperative for the health care system to address late-life mental disorders more effectively. Intervention strategies based in primary care settings show the most promise, but effectiveness will depend on solving the geriatric psychiatry workforce crisis. Collaborative care is one promising model for improving geriatric mental health care delivery in primary care. Diffusion of collaborative care into the health care system and integrating geriatric psychiatry into other models such as geriatric medical homes will require redesign of the organization and financing of primary care and psychiatry to overcome current barriers. Public policy should reflect the essential role of psychiatry in geriatrics and promote the integration of geriatric psychiatry with primary care.     

The impact of deferring retirement age on retirement income adequacy

UPDATE OF RSPM-POST-65 RETIREMENT AGES: The EBRI Retirement Security Projection Model (RSPM) was developed in 2003 to provide an assessment of national retirement income prospects. The 2011 version of RSPM adds a new feature that allows households to defer retirement age past age 65 in an attempt to determine whether retirement age deferral is indeed sufficiently valuable to mitigate retirement income adequacy problems for most households (assuming the worker is physically able to continue working and that there continues to be a suitable demand for his or her skills). The answer, unfortunately, is not always "yes," even if retirement age is deferred into the 80s. LOWEST-INCOME LEVELS, 50-50 CHANCE OF ADEQUACY: RSPM baseline results indicate that the lowest preretirement income quartile would need to defer retirement age to 84 before 90 percent of the households would have a 50 percent probability of success. Although a significant portion of the improvement takes place in the first four years after age 65, the improvement tends to level off in the early 70s before picking up in the late 70s and early 80s. Households in higher preretirement income quartiles start at a much higher level, and therefore have less improvement in terms of additional households reaching a 50 percent success rate as retirement age is deferred for these households. LOWEST-INCOME LEVELS, HIGHER CHANCES OF ADEQUACY: If the success rate is moved to a threshold of 70 percent, only 2 out of 5 households in the lowest-income quartile will attain retirement income adequacy even if they defer retirement age to 84. Increasing the threshold to 80 percent reduces the number of lowest preretirement income quartile households that can satisfy this standard at a retirement age of 84 to approximately 1 out of 7. IMPORTANCE OF DEFINED CONTRIBUTION RETIREMENT PLANS: One of the factors that makes a major difference in the percentage of households satisfying the retirement income adequacy thresholds at any retirement age is whether the worker is still participating in a defined contribution plan after age 65. This factor results in at least a 10 percentage point difference in the majority of the retirement age/income combinations investigated. FACTORING IN RETIREMENT HEALTH COSTS: Another factor that has a tremendous impact on the value of deferring retirement age is whether stochastic post-retirement health care costs are excluded (or the stochastic nature is ignored). For the lowest preretirement income quartile, the value of deferral (in terms of percentage of additional households that will meet the threshold by deferring retirement age from 65 to 84) decreases from 16.0 percent to 3.8 percent by excluding these costs. The highest preretirement income quartile experiences a similar decrease, from 12.8 percent to 2.6 percent.
