Koordination durch heuristische Budgetierungsverfahren

If in companies decisions are decentralised coordination problems arise. Controlling offers different instruments for coordination. Among these, budgeting is very popular. In a centralized model it is shown how capacity allocation as well as transfer pricing coordinate under the constraints of budgeting. These two principles are combined with the process of budgeting in form of a top down, bottom up or counter current planning. From the resulting nine possible combinations only five are of practical relevance. These five cases are heuristics to the coordination problem, they are analysed by extensive example calculations. It is shown that transfer pricing coordinates better than capacity allocation and counter current planning is the dominant process of budgeting. The best results are obtained with transfer pricing closing with capacity allocation.     

Patients' race, ethnicity, language, and trust in a physician

We examine whether racial/ethnic/language-based variation in measured levels of patients' trust in a physician depends on the survey items used to measure that trust. Survey items include: (1) a direct measure of patients' trust that the doctor will put the patient's medical needs above all other considerations, and (2) three indirect measures of trust asking about expectations for specific physician behaviors, including referring to a specialist, being influenced by insurance rules, and performing unnecessary tests. Using a national survey, we find lower scores on indirect measures of trust in a physician among minority users of health care services than among non-Hispanic white users. In contrast, the direct measure of trust does not differ among non-Hispanic whites and nonwhites once we control for potential confounding factors. The results indicate that racial/ethnic/language-based differences exist primarily in those aspects of patients' trust in a physician that reflect specific physician behaviors.     

Complicated grief symptoms in caregivers of persons with lung cancer: the role of family conflict, intrapsychic strains, and hospice utilization

Guided by a stress process conceptual model, this study examines social and psychological determinants of complicated grief symptoms focusing on family conflict, intrapsychic strains, and the potential moderating effect of care quality and hospice utilization. Relying on data from 152 spouse and adult child lung cancer caregiver survey respondents, drawn from an ancillary study of the Assessment of Cancer CarE and SatiSfaction (ACCESS) in Wisconsin, hierarchical multiple regression analysis was used to examine determinants of complicated grief. After controlling for contextual factors and time since death, complicated grief symptoms were higher among caregivers with less education, among families with lower prior conflict but higher conflict at the end-of-life, who had family members who had difficulty accepting the illness, and who were caring for patients with greater fear of death. Additionally, hospice utilization moderated the effect of fear of death on complicated grief. Findings suggest that family conflict, intrapsychic strains, and hospice utilization may help to explain the variability found in complicated grief symptoms among bereaved caregivers. Implications for enhancing complicated grief assessment tools and preventative interventions across the continuum of cancer care are highlighted.

Democracy for whom? How criminal punishment marginalizes the political voices of Black and Brown Americans

U.S. racialized punishment practices have long harmed communities of color in sundry ways, including access to democratic processes. Synthesizing scholarship on punishment and democracy that centers the lived experiences and political subjectivities of Black and Brown Americans, we argue that criminal punishment is a powerful form of political marginalization that diminishes the political voices of Black and Brown Americans en masse and simultaneously amplifies the voices of White Americans. To illuminate how punishment (re)produces systemic racial inequities in democratic processes, we focus on two distinct but related marginalizations: disenfranchisement for a felony conviction and prison gerrymandering. These deep-rooted “colorblind” policies did not draw scholarly attention until recent decades, well after district boundaries and election outcomes across the country were impacted. To help understand that delay, we highlight the utility of applying an emancipatory, Du Boisian lens with an example from our past work. Looking to the future, we argue that DuBois's tenets should inform punishment scholarship regardless of methodology or data type. Doing so will help identify more hidden forms of political marginalization in a timely manner, enable scholars to investigate the potential multiplicative effects of those marginalizations, and increase the potential impact of that work beyond the academy.     

Estimation of common location parameter of several heterogeneous exponential populations based on generalized order statistics

In this article, several independent populations following exponential distribution with common location parameter and unknown and unequal scale parameters are considered. From these populations, several independent samples of generalized order statistics (gos) are drawn. Under the setup of gos, the problem of estimation of common location parameter is discussed and various estimators of common location parameter are derived. The authors obtained maximum likelihood estimator (MLE), modified MLE and uniformly minimum variance unbiased estimator of common location parameter. Furthermore, under scaled-squared error loss function, a general inadmissibility result of invariant estimator is proposed. The derived results are further reduced for upper record values which is a special case of gos. Finally, simulation study and real life example are reported to show the performances of various competing estimators in terms of percentage risk improvement.     

A Third Sector in the Third Millennium?

Three trends since the 1960s underscore the need for different ways of conceptualizing the new mixed economy in the human services. First, there has been an enormous increase in the number and types of nonprofit organizations, and greater dependence on governmental revenue. Second, extensive growth in privatization and commercialization in the human services. Third, this culminated in the convergence and blurring of sectoral boundaries. Numerous metaphors have been suggested to describe these new patterns, but more suitable concepts and theories are needed. Four theoretical frameworks are analyzed for an intersectoral study of organizations in the same industry: (1) political economy, (2) organizational ecology, (3) neoinstitutionalism, and (4) mixed, open systems. As analytic paradigms, these frameworks could supplement, complement, or be integrated with other research models for third sector studies, and could contribute to theory building and social policy.     

Physical victimization of rural methamphetamine and cocaine users

Substance use and physical violence often coincide, but little has been published on the correlates associated with receipt of partner versus nonpartner physical violence for rural users of methamphetamine and/or cocaine. In this study, participants' substance use, depression and past-year physical victimization were assessed. In separate logistic regression models, received partner violence in females was associated with age; alcohol, cocaine, and methamphetamine abuse/dependence; and number of drugs used in the past 6 months. In males, received nonpartner violence was associated with age, cocaine abuse/dependence, and being Caucasian. Findings suggest a relationship between stimulant use and received violence among rural substance users and a need for victimization screenings in settings where such individuals seek health care.     

From bedside to bench: does mental and physical activity promote cognitive vitality in late life?

A wide range of animal and human studies provide evidence for the potential of physical and cognitive exercise in promoting cognitive health later in life. The effects of such activities on intermediate outcomes, such as cognitive performance, are becoming clearer, as are the molecular mechanisms involved. Physical and cognitive exercise might increase "cognitive reserve" and increase the overall health of the brain, thereby reducing or delaying cognitive impairment and dementia. However, conclusive evidence for such benefits is not yet established. The third annual Bedside to Bench conference, cosponsored by The American Geriatrics Society and the National Institutes of Health's National Institute on Aging, reviewed current knowledge regarding the role of physical and cognitive exercise in promoting cognitive vitality. Conference attendees identified gaps in our current understanding of these processes and recommended next steps for research. In particular, researchers will need to explore clinical issues related to the timing, intensity, and duration of various types and combinations of physical and cognitive activities in animal models to elucidate the mechanisms involved and inform the design of future human studies. The concept of the enriched environment currently employed in animal studies to promote physical activity, socialization, and problem solving should be explored in human studies.
