Squeezing or cuddling? The impact of economic crises on management control and stakeholder management

This paper analyzes the effects of economic crises on firms’ use of management control mechanisms and on their management of stakeholder relations. Moreover, the association between stakeholder management and management control system use is analyzed. In the wake of the economic crisis of 2008/2009, many firms were faced with severe threats that called for immediate short-term action to ensure firm survival. However, short-term action like massive cost-cutting and cash generation often are blamed for going at the expense of long-term health as key stakeholder relations may be irreversibly harmed. Hence, three interrelated questions are addressed theoretically and empirically: First, we analyze the impact of the recent economic crisis on firms’ control strategies. More specifically, we investigate whether a high crisis impact on firms is associated with a shortening of reporting cycles, a more interactive use of control-relevant information, restriction of employee autonomy and a focus on liquidity and cost-cutting. Second, we examine from the viewpoint of stakeholder theory how firms can make use of active stakeholder management for crisis management. Third, we explore whether firms can take short-term measures for ensuring liquidity and cutting costs and at the same time pursue a stakeholder strategy aiming at the long-term survival of the firm. Using survey data from 204 major Austrian corporations, we provide evidence that firms significantly adjusted their control systems as a response to the economic crisis. Our data do not indicate an immanent contradiction between a “short-term finance focus” and the pursuit of a sustainable stakeholder strategy.

CHARISMA,CANNABIS, AND THE CROSSING OF AFRICA

This essay, based on a chapter from a forthcoming study of the exploration of Central Africa, tells the story of the encounter between the German travelers Paul Pogge and Hermann Wissmann and a charismatic extatic cult or movement, the 'Children of Hemp.' With the aid of the movement Wissmann accomplished the first documented crossing of the continent (from West to East). Eventually he was also material in drawing the leaders of what was essentially a modernization movement into the organization of what became the Congo Free State. A tale of trust and friendship betrayed and chances missed, of exploration turning into occupation, and of grave consequences for the Congo up to the present.     

TANF child-only cases in California: Barriers to self-sufficiency and well-being

Since the United States implemented Temporary Assistance to Needy Families (TANF), or ‘welfare reform,’ the number of assistance cases without an adult receiving aid has risen dramatically. In states like California, these child-only cases now constitute the majority of all TANF cases. Despite this increase, existing research sheds little light on the composition of child-only caseloads and the status of the adults and children in such cases. Drawing on county administrative data and interviews with 143 parents associated with child-only cases in five California counties, this paper identifies both the demographics of the child-only caseload in these sites and the major barriers to employment that parents in sanctioned and timed-out child-only cases face. These include human capital, health, and family issues, in addition to other obstacles. The data suggest that, despite functioning as one administrative entity, CalWORKs, California's TANF program, has transformed into two separate programs: a welfare-to-work program and a subsistence-level cash assistance program for some members of child-only families. Given this transformation, the paper closes by suggesting a research agenda for future child-only scholarship and argues for policy innovations to meet the needs of the expanding child-only caseload.     

Projects in Introductory Statistics Courses

Introductory statistics courses should incorporate unstructured projects where students themselves generate the problems they choose to study, gather their own data, analyze the information using suitable computer software, and communicate their findings in a report. This article describes my experience with projects in the context of a large lecture course where projects are carried out in groups. Special problems that arise with group projects are discussed. Several successful student projects are described.     

Occupational stress and cardiovascular reactivity in blue-collar workers

This study analyses the influence of chronic occupational stress on cardiovascular reactivity (heart rate [HR] and blood pressure [BP] elevation from baseline to maximal challenge) during a standard mental stress test (modified version of the STROOP colour word interference test). The test was applied to a sample of 190 healthy male blue-collar workers at the end of a regular working day. Our research hypothesis was based on the assumption that sustained autonomic activation due to chronic occupational stress may reduce cardiovascular responsiveness to challenge: workers defined by high level of chronic occupational stress exhibited lower maximal HR and BP elevations under challenge as compared to workers with low levels of stress. Three distinct indicators of occupational stress were derived from structured interviews: 'cumulative workload', 'worsening of job conditions', and 'high demand and low job security'. Statistical analysis, using ANOVA, showed that all main effects of chronic stress were in the expected direction (6 of 9 effects were statistically significant at the 0'05 level). These effects remained stable after adjusting for age, hypertensive status, physiological baseline level, cigarette smoking, test performance, and individual style of coping. In summary, cardiovascular reactivity under experimental challenge is modulated by an individual's experience of chronic occupational stress.     

Estimation Bias in the First-Order Autoregressive Model and Its Impact on Predictions and Prediction Intervals

The least squares estimate of the autoregressive coefficient in the AR(1) model is known to be biased towards zero, especially for parameters close to the stationarity boundary. Several methods for correcting the autoregressive parameter estimate for the bias have been suggested. Using simulations, we study the bias and the mean square error of the least squares estimate and the bias-corrections proposed by Kendall and Quenouille.

We also study the mean square forecast error and the coverage of the 95% prediction interval when using the biased least squares estimate or one of its bias-corrected versions. We find that the estimation bias matters little for point forecasts, but that it affects the coverage of the prediction intervals. Prediction intervals for forecasts more than one step ahead, when calculated with the biased least squares estimate, are too narrow.     

Forecast efficiency of systematically sampled time series

In this paper we consider the effect of the sampling interval in systematically sampled time series on the forecast efficiency. We find that for sufficientlv long sampled series the loss in forecasting accuracy by using the sampled instead of the original series is small     

Connecting sleep,the neurocognitive memory system,and Bourdieu's habitus concept: Is sleep a generative force of the habitus?

Bourdieu's habitus theory has been criticized for allegedly being static and deterministic. This is partly due to insufficiently elaborated microstructural aspects of the habitus. Previous works have tried to elaborate the habitus' individual side by drawing on neuropsychological and neuroscientific concepts including the neuropsychological memory system. Despite its relevance for several social processes, sleep has not been considered in this context. The present work investigates the interrelatedness of habitus, sleep, and the memory system with particular focus on the determinism and staticity critique. It shows that the neuropsychological memory system overlaps largely with implicit memory and sleep plays an important role in the formation of habitus‐relevant memory. Moreover, sleep enhances processes such as memory consolidation, reflexivity, associative creativity, and dream‐associated simulation of unknown situations which counter the determinism and staticity critique. The present article argues that habitus, memory, and sleep are closely related and memory and sleep represent operational micro‐structures of the habitus. Moreover, sleep‐related processes represent a generative force that renders the habitus more dynamic. Finally, strengths and weaknesses of the habitus‐memory‐sleep nexus are discussed and further lines of research are outlined.     

Sexual functioning and practices in a multi‐ethnic study of midlife women: Baseline results from swan

This study examined the sexual practices and function of midlife women by ethnicity (African American, Caucasian, Chinese, Hispanic, Japanese) and menopausal status. Sexual behavior was compared in 3,262 women in the baseline cohort of SWAN. Participants were 42 to 52 years old, premenopausal or early perimenopausal, and not hysterectomized or using hormones. Analysis used multivariate proportional odds regression. In our sample, 79% had engaged in sex with a partner in the last 6 months, and a third considered sex to be very important. Common reasons for no sex (n = 676) were lack of partner (67%), lack of interest (33%), and fatigue (16%). Compared with Caucasians, Japanese and Chinese women were less likely, and African Americans more likely, to report sex as very important (p < 0.005). Significant ethnic differences were found for frequency of all practices. Perimenopause status was associated only with higher frequencies of masturbation and pain during intercourse.
