Green human resource management: Development of a valid measurement scale

The objective of the study was to develop a valid measurement scale for green human resource management (HRM). Even though the common practices of green HRM have been presented in much of the literature, the previous studies focused only on a small number of functions in integrating environmental management with HRM. Additionally, the measurement of green HRM practices still calls for empirical validation. The two‐stage methodology of structural equation modeling in AMOS was employed for data analysis. Exploratory factor analysis revealed seven dimensions of the construct measured by 28 items. Confirmatory factor analysis confirmed the factor structure. The measuring instruments revealed convergent and discriminant validity. Several model fit indices indicated the model fitness. The study provided supplementary evidence on the underlying structure of the construct that can be valuable to researchers and practitioners in this area.     

Internal green integration and environmental performance: The predictive power of proactive environmental strategy,greening the supplier,and environmental collaboration with the supplier

The effect of proactive environmental strategies (PES) on corporate performance has been debated extensively among academics; however, the significance of the pathway of those strategies—internal green integration (IGI) through greening the supplier (GTS) and environmental collaboration with suppliers (ECS)—remains undecided. This study examines environmental performance (EP) through GTS, IGI, and ECS. It also examines the direct link between PES and IGI. A conceptual framework was designed following a rigorous review of the literature. A survey questionnaire was used to collect cross-sectional data from a random sample of manufacturing firms, obtaining 196 usable samples. Using AMOS, the structural equal modeling found a positive and significant impact of PES on IGI. Significant predictors of EP were GTS, IGI, and ECS. The findings of the study can provide managers with guidelines for dealing with business and environmental concerns. They can also contribute to creating strategies for environmental protection and management and reducing adverse effects on the environment. Finally, by examining the direct links between GTS, ECS, and EP, particularly in a developing context, the study may contribute to the literature of environmental policy.     

The Pricing Kernel Puzzle: A Real Phenomenon or a Statistical Artifact?

A large literature finds evidence that the pricing kernels estimated from option prices and historical returns are not monotonically decreasing in market returns. We show that the inevitable coalescence of contingencies, especially in the left‐tail, associated with estimating a distribution function may give rise to a nonmonotonic empirical pricing kernel even if the actual pricing kernel is monotonic. Hence, the observed nonmonotonicity of pricing kernels may be a statistical artifact rather than a real phenomenon. We argue that empirical work should explicitly correct for this effect by widening the option pricing bounds associated with monotonic pricing kernels.     

The relationship between laissez-faire leadership and burnout: Mediation through work alienation and the moderating role of political skill

We tested the relationship between laissez-faire leadership and job burnout and the mediating role of work alienation in this relationship. We also examined the moderating role of political skill in the relationship between laissez-faire leadership and burnout. Based on time-lagged (three waves, two months apart) survey data collected from 272 employees in 92 firms operating in China, our results showed that laissez-faire leadership was positively related to burnout both directly and via work alienation. Moreover, the positive relationship between laissez-faire leadership and burnout was contingent on political skill, such that the relationship was weak when political skill was high. The study provides useful suggestions to help managers curb employees' feelings of burnout and work alienation.     

Economic burden associated with inadequate antidepressant medication management among patients with depression and known cardiovascular diseases: insights from a United States–based retrospective claims database analysis

Abstract

Aims: The current study examined the association between insufficient major depressive disorder (MDD) care and healthcare resource use (HCRU) and costs among patients with prior myocardial infarction (MI) or stroke.

Methods: This was a retrospective study conducted using the MarketScan Claims Database (2010–2015). The date of the first MI/stroke diagnosis was defined as the cardiovascular disease (CVD) index date and the first date of a subsequent MDD diagnosis was the index MDD date. Adequacy of MDD care was assessed during the 90 days following the index MDD date (profiling period) using 2 measures: dosage adequacy (average fluoxetine equivalent dose of ≥20?mg/day for nonelderly and ≥10?mg/day for elderly patients) and duration adequacy (measured as the proportion of days covered of 80% or higher for all MDD drugs). Study outcomes included all-cause and CVD-related HCRU and costs which were determined from the end of the profiling period until the end of study follow-up. Propensity-score adjusted generalized linear models (GLMs) were used to compare patients receiving adequate versus inadequate MDD care in terms of study outcomes.

Results: Of 1,568 CVD patients who were treated for MDD, 937 (59.8%) were categorized as receiving inadequate MDD care. Results from the GLMs suggested that patients receiving inadequate MDD care had 14% more all-cause hospitalizations, 4% more all-cause outpatient visits, 17% more CVD-related outpatient visits, 13% more CVD-related emergency room (ER) visits, higher per patient per year CVD-related hospitalization costs ($21,485 vs. $17,756), higher all-cause outpatient costs ($2,820 vs. $2,055), and higher CVD-related outpatient costs ($520 vs. $434) compared to patients receiving adequate MDD care.

Limitations: Clinical information such as depression severity and frailty, which are potential predictors of adverse CVD outcomes, could not be ascertained using administrative claims data.

Conclusions: Among post-MI and post-stroke patients, inadequate MDD care was associated with a significantly higher economic burden.     

Accident risk analysis based on motorway exposure: an application of benchmarking technique for human safety

Abstract

Accident risk analysis for human safety and infrastructural improvement are key requirements of the engineering sector. The purpose of this paper is to identify and prioritize problematic segments of roads based upon the risk evaluation concept and to focus on the severity of accidents regarding human life loss and easy manoeuvring. This study includes the concept of considering road segments as decision-making units for application of data envelopment analysis (DEA) technique which has no compulsion of the distribution function and critical assumptions, unlike the multiple regression models. According to the proposed methodology, a section of Motorway (M-2) Lahore-Islamabad has been analyzed. Out of 200 segments under consideration, 99 segments were selected with at least one accident and one injury or fatality. Furthermore, for risk calculation and ranking of road segments, the DEA technique along with the cross-risk matrix method was applied. This optimization technique could not only be helpful in ranking but also technical decision-making and prioritizations for safety improvement, policymaking and budget allocation.     

Investigating the Drivers of Consumer Acceptance and Response of SMS Advertising

This study tests five potential drivers underlying the acceptance of SMS advertising. After developing a scale to measure behavioral responses to SMS advertising, the relationships between the acceptance of SMS advertising, intention to receive SMS advertising and behavioral responses to SMS advertising are tested. A convenience sampling method was employed. Survey questionnaires were distributed across Western Australia. The return yielded 203 usable questionnaires from the respondents. Several factors emerge as significant drivers of acceptance of SMS advertising including utility of SMS advertisements, context of SMS advertisements and attitudes to advertising in general. Contrary to expectation, control over SMS advertisements did not emerge as a significant driver for acceptance of SMS advertising. Trust in advertisers and laws did not emerge as a significant driver of the acceptance of SMS advertising among Australian respondents. Advertisers who pursue consumer acceptance should strive to build utility and context considerations into their SMS campaigns. Future research opportunities include testing the drivers of SMS advertising to further investigate the impact of control and trust on acceptance of SMS advertising in other countries where the SMS advertising has not been explored yet.     

Migrant remittances and fertility

This study examines the role of migrants’ remittances in developing countries’ fertility transition. Employing an unbalanced panel of South Asian countries and controlling for various economic and socio-demographic factors, we find that remittances are significantly associated with a lower number of children born to women of childbearing age. This suggests the remittances’ substitution effect to be at play rather than the income effect, and may result from decreased need for children for financing the household’s future needs as well as from better access to healthcare and contraceptive methods available to migrant households. Remittances’ association with fertility appears to be more important than the transfer of fertility norms from migrants’ host countries. The monetary aspects of international migration may therefore be more important for the region’s demographic transition than social remittances.     

Capital account flows,consumption ratios and the middle‐income trap

The existing literature suggests that it is important to understand the factors that may slow the transition of an economy from middle to high income. Many factors have been suggested as promoting or retarding economic growth, but little attention has been paid to the roles of the capital account and consumption ratio. Using panel regressions involving 48 countries over the 1950–2013 period as well as employing extreme bounds analysis, we find that foreign investment outflows are associated with a mature economy and that there is an optimal consumption ratio that must be surpassed to break out of middle‐income status. These findings are robust to an extreme bounds analysis incorporating a wide range of variables potentially related to growth performance.
