Transient Health Shocks and Agricultural Labor Demand in Rice-producing Households in Mali

Malaria and other transient illnesses have been recognized as factors constraining economic development in tropical countries. The purpose of this paper is to determine the direct and the indirect impact of transient illness shocks, caused primarily by malaria but also including other tropical illness, on family labor use in irrigated rice production in Mali. Family labor is the most important factor of production used in rice production in Mali and transient illness shocks may negatively impact labor supply, production and hence household welfare derived from agricultural income and consumption. Two labor demand models are estimated to determine whether illness does indeed reduce labor supply: one where the dependent variable only includes family labor and a second that combines family and hired labor. These models can be used to test two sets of hypotheses on the relationship between illness and labor supply. First, we hypothesize that short-term transient illness shocks affect household labor supply implying that intrahousehold coping mechanisms are not wholly effective. Secondly, we hypothesize that hired labor markets are ineffective in mitigating illness shocks. We find that direct and indirect health shocks reduce the effective supply of labor and that neither household nor market supply of labor can mitigate these shocks.D1, I0, Q12, Crop Production/Industries, Labor and Human Capital,

Meta-analyses of Post-acquisition Performance: Indications of Unidentified Moderators

Empirical research has not consistently identified antecedents for predicting post-acquisition performance. We employ meta-analytic techniques to empirically assess the impact of the most commonly researched antecedent variables on post-acquisition performance. We find robust results indicating that, on average and across the most commonly studied variables, acquiring firms’ performance does not positively change as a function of their acquisition activity, and is negatively affected to a modest extent. More importantly, our results indicate that unidentified variables may explain significant variance in post-acquisition performance, suggesting the need for additional theory development and changes to M&A research methods

Corporate Governance in the Small Firm: Prescriptions for CEOS and Directors

Examinations of boards of directors of smaller corporations have been largely absent from the academic literature. This study addresses this void by examining several aspects of commonly prescribed board configurations for entrepreneurial (high growth) and small (stable growth ) corporations. Specifically, we address board composition and board leadership structure, as well as the impact of officer and director stock holdings and institutional holdings. Stepwise multiple regression analysis  reveals  that  these  governance   variables significantly  add  to  the  explanation of financial performance for both sets of firms. The implications of these findings for Chief Executive Officers (CEOs) and boards of directors are discussed

Lectio Divina: A Contemplative Pedagogy for Promoting Embodied and Creative Learning in Higher Education Classrooms

Lectio divina offers tools for creativity and discovery that engage students in embodied learning processes. This article explores lectio divina as an approach to teaching and learning in higher education that cultivates students’ multi-dimensional engagement in the classroom. Professors from English, Teacher Education, and Art Education share portraits from practice that successfully use lectio divina with creative work such as poems, story, and visual images on an intermittent basis in the classroom. These examples offer additional approaches to the use of lectio divina and provide practical glimpses into this contemplative approach as a creative and embodied pedagogy. Once a monastic practice, lectio divina has emerged as a contemporary contemplative practice that offers a pedagogical method aligned with many efforts in the 21st century to cultivate and value all dimensions of being human: mind, body, spirit

Structured, aerobic exercise reduces fat mass and is partially compensated through energy intake but not energy expenditure in women

Background Exercise-induced weight loss is often less than expected and highly variable in men and women. Behavioural compensation for the exercise-induced energy deficit could be through energy intake (EI), non-exercise physical activity (NEPA) or sedentary behaviour (SB). We investigated this issue in women. Methods Twenty-four overweight [body mass index (BMI) M = 27.9 kg/m2, SD = 2.7] women [age M = 33.1 years, SD = 11.7] completed 12-weeks of supervised exercise (5×500kcal per week) in a non-randomised pre-post intervention study. Body mass (BM), waist circumference (WC), body composition, resting metabolic rate (RMR), total daily EI, individual meals, appetite sensations and appetite-related peptides were measured at baseline (week 0) and post-intervention (week 12). Free-living physical activity (PA) and SB were measured (SenseWear) at baseline, week 1 and 10 of the exercise intervention, and at post-intervention (week 13). Results Following the 12-week exercise intervention BM [p = .04], BMI [p = .035], WC [p  .05]. There was no compensatory reduction in NEPA [p > .05] and no increase in SB, rather there was a decrease in SB during the exercise intervention [p = .03]. Conclusions Twelve-weeks of supervised aerobic exercise resulted in a significant reduction in FM and an increase in FFM. Exercise increased hunger and EI which only partially compensated for the increase in energy expenditure. There was no evidence for a compensatory reduction in NEPA or an increase in SB. Dietary intervention, as an adjunct to exercise, may offset the compensatory increase in EI and result in a greater reduction in BM

PHOSPHATIDYLCHOLINE CONTAINING LONG CHAIN OMEGA-3 FATTY ACIDS: A TREATMENT ADJUNCT FOR PATIENTS WITH ANOREXIA NERVOSA?

Background: Anorexia nervosa (AN) is a serious mental disorder with a high mortality rate and often a chronic course. In contrast to many other common mental disorders, there is no drug therapy approved for AN. Methods: We performed a narrative literature review to consider whether a choline-containing molecule, such as phosphatidylcholine (PC), with an omega (ω)-3 long chain polyunsaturated fatty acid (LCPUFA) could be a potential future medicinal treatment for AN. Results: Choline and LCPUFAs have individually shown benefit for mental health. Case series and pilot studies suggest ω -3 LCPUFAs may be effective in eating disorders. However, pharmacodynamic and pharmacokinetic considerations suggest a greater benefit from the combination of both components. Conclusion: The combination of a choline-containing molecule with an ω-3 LCPUFA may be clinically effective and well tolerated. This idea is supported by the current literature on the role of inflammation, the microbiome, the gut-brain-axis, hormonal, neurotransmitter and intracellular signalling, and on the structure and fluidity of nerve cells membranes in patients with AN

A novel integrative procedure for identifying and integrating three-dimensions of objectively measured free-living sedentary behaviour

The widely accepted definition of sedentary behaviour [SB] refers to any waking behaviour characterized by an energy expenditure ≤1.5 metabolic equivalents [METs] while in a sitting or reclining posture. At present, there is no single field-based device which objectively measures sleep, posture and activity intensity simultaneously. The aim of this study was to develop a novel integrative procedure [INT] to combine information from two validated activity monitors on sleep, activity intensity and posture, the three key dimensions of SB

Autonomous Multi-Stage Flexible OPF for Active Distribution Systems with DERs

The variability of renewable resources creates challenges in the operation and control of power systems. One way to cope with this issue is to use the flexibility of customer resources in addition to utility resources to mitigate this variability. We present an approach that autonomously optimizes the available distributed energy resources (DERs) of the system to optimally balance generation and load and/or levelize the voltage profile. The method uses a dynamic state estimator which is continuously running on the system providing the real-time dynamic model of the system and operating condition. At user selected time intervals, the real-time model and operating condition is used to autonomously assemble a multi-stage optimal power flow in which customer energy resources are represented with their controls, allowing the use of customer flexibility to be part of the solution. Customer DERs may include photovoltaic rooftops with controllable inverters, batteries, thermostatically controlled loads, smart appliances, etc. The paper describes the autonomous formation of the Multi-Stage Flexible Optimal Power Flow and the solution of the problem, and presents sample results

Disentangling the relationship between sedentariness and obesity: Activity intensity, but not sitting posture, is associated with adiposity in women

Background The relationship between free-living sedentary behaviour (SB) and obesity is unclear. Studies may arrive at disparate conclusions because of inconsistencies and limitations when defining and measuring free-living SB. The aim of this cross-sectional study was to examine whether the relationship between SB and adiposity differed depending on the way SB was operationally defined and objectively measured. Methods Sixty-three female participants aged 37.1 years (SD = 13.6) with a body mass index (BMI) of 29.6 kg/m2 (SD = 4.7) had their body composition measured (BodPod, Concord, CA) then were continuously monitored for 5–7 days with the SenseWear Armband (SWA; sleep and activity intensity) and the activPAL (AP; posture). Data from both activity monitors were analysed separately and integrated resulting in a third measure of SB (activity intensity and posture; SEDINT). SB outputs were compared according to week or weekend day averages then correlated against body composition parameters after adjusting for moderate-to-vigorous physical activity (MVPA). Results SEDSWA resulted in the most sedentary time 11.74 h/day (SD = 1.60), followed by SEDAP 10.16 h/day (SD = 1.75) and SEDINT 9.10 h/day (SD = 1.67). There was a significant positive association between SEDSWA and body mass [r(61) = 0.29, p = .02], BMI [r (61) = 0.33, p = .009] and fat mass [r(61) = 0.32, p = .01]. SEDAP and SEDINT were not associated with any of the indices of adiposity. Correlations between SB and adiposity were non-significant when controlling for MVPA. Conclusions The relationship between SB and adiposity differed depending on how SB was operationally defined and measured, and was dependent on MVPA. The definition of SB based on a sitting posture (SEDAP) was not strongly related to body fat, whereas the accumulation of any behaviour (sitting or standing) with an intensity of <1.5 METs (SEDSWA) (offset by the presence of MVPA) was positively associated with indices of adiposity. These data suggest that the postural element of SB (sitting) is not sufficient for the accumulation of adiposity, rather activities requiring low EE (<1.5 METs) and the absence of MVPA, regardless of posture, are associated with higher fat mass
