Designing a sustainable integrated forward/reverse logistics network
Authors: Farrokhi-Asl Hamed , Makui Ahmad , Ghousi Roozbeh , Rabbani Masoud 
Published: October 2019

Purpose
In recent years, governmental regulations and the pressure of non-governmental organizations have convinced corporations to consider sustainable issues in their decisions. A simultaneous design of forward and reverse logistics can keep us away from sub-optimality caused by tackling these two phases (forward and reverse logistics) separately.

Design/methodology/approach
Hence, this paper presents a new multi-objective mathematical model for integrated forward and reverse logistics regarding economic, environmental and social issues. A new hybrid multi-objective metaheuristic algorithm is developed to obtain a set of efficient solutions (Pareto solutions). The proposed algorithm hybridizes a well-known, non-dominated genetic algorithm (NSGA-II) with a simulated annealing algorithm.

Findings
To validate the algorithm, its results are compared to the obtained solutions from simple NSGA-II with respect to some comparison metrics. The numerical results show the efficiency of the proposed algorithm. Finally, concluding remarks and future research directions are provided.

Originality/value
By applying a model presented in this paper, one can reach to sustainable and integrated logistics network which considers forward and reverse flow of commodities simultaneously.
Transformational leadership, organizational justice and organizational outcomes
Authors: Alamir Iyad , Ayoubi Rami M. , Massoud Hiba , Hallak Louna Al 
Published: October 2019

PurposeThe purpose of this paper is to examine the impact of transformational leadership (TL) on organizational commitment (OC) with the mediating role of organizational justice (OJ) in the higher education (HE) sector in Syria.Design/methodology/approachThe data were collected from 502 employees from six HE institutions. Two measures of organizational outcomes were selected for this study, namely, job satisfaction (JS) and OC. Using structural equation modelling (SEM), the authors tested four alternative models to indicate the relationship between leadership and organizational outcomes.FindingsTL has both direct and indirect effects on OC through interactional justice (IJ). TL has an impact on JS through procedural justice (PJ) and IJ as intermediate variables, while transactional leadership (TrL) has an impact on JS through distributive justice (DJ). The three types of OJ have an impact on OC through JS. The authors found that the national culture may not influence the impact of the leader in the current globalization context, as the results were similar to the Western studies.Practical implicationsThe findings of the study provide managers of the HE sector with insights into the formations of employees’ fairness perceptions, and with some guidelines for managing employees by documenting OJ to draw positive attitudinal and behavioral responses from employees.Originality/valueWhile most previous research has focused on exploring the relationship between leadership and OJ or between OJ and JS in the business sector, the study, however, seeks in addition, to pinpoint the effect of OJ as a mediate variable between the leadership and JS and OC in HE.
Water governance in the USA
Authors: Silva Rodríguez de San Miguel Jorge Alejandro 
Published: October 2019

PurposeThe purpose of this paper is to look at how the topic of water governance in the USA reflects the discussion just prior to the contemporary wave of privatisation that now characterises a large section of water in the country.Design/methodology/approachIn addition to select classic articles, the body of literature chosen for review includes studies published between 2000 and 2019, using The PRISMA statement. Studies chosen were published in recognised journals in core disciplines relating to governance, water management, policy and regulation.FindingsPrivate equity firms and water-focused investment funds are significant investors in private companies that operate municipal water works in the USA. This has caused much of the public water infrastructure in the country (and globally) to become privatised and held by international investors as securitised assets.Research limitations/implicationsThere is a need for further primary research to more comprehensively capture what actions the US government are taking to carve out a large policy-making space for themselves in a country that there is not an extensive body of literature on takeover decisions in water governance.Originality/valueThe confluence of privatisation in water governance within the US government is an area of growing concern to those interested in how water governance systems and protocols shape broader justice and equality developments across the country.
Entrepreneurial orientation and firm performance: an updated meta-analysis
Authors: Soares Mauren do Couto , Perin Marcelo Gattermann 
Published: October 2019

Purpose
The purpose of this paper is to analyze the relationship between entrepreneurial orientation (EO) and organizational performance through an updated and extended meta-analytic review that includes EO, mediators, moderators and performance results.

Design/methodology/approach
Using Pearson correlations as effect size statistics, and based on 80 independent samples from 78 studies, with a total sample size of 19,514 cases, the meta-analysis consolidates the empirical findings of this field of research.

Findings
The results reveal that there is a direct and positive impact of EO on organizational performance, and this effect is stronger for multi-item measures of performance and for revenue-based performance measures. In addition, the authors found partial mediation effects of learning orientation and innovativeness on the relationship between EO and firm performance.

Originality/value
The work contributes to the literature by demonstrating the importance of EO to organizational performance with a meta-analysis, reporting the partially mediating variables in this relationship and seeking to explain the observed inconsistencies in preceding results, also examining methodological moderating variables. Hence, the research extends previous meta-analytic studies done in the area.

Entrepreneurial leadership and business performance
Authors: Paudel Samundra 
Published: October 2019

PurposeThe purpose of this paper is to examine effects of entrepreneurial leadership (EL) and organizational innovation (OI) on business performance (BP) of small and medium enterprises (SMEs) as well as to determine whether environmental dynamism (ED) moderates the mediating effect of OI in the EL‒BP relationship.Design/methodology/approachThe study was carried out on the basis of questionnaire survey among 243 SME owners of Pokhara valley of Nepal. Hierarchical multiple regression and other different PROCESS models were considered to examine direct, mediation, moderation and moderated mediation relationships.FindingsThe findings suggest a significant positive effect of EL on OI and BP and significant mediating role of OI in EL‒BP relationship. But contrary to the prediction, the results indicate that the moderation and moderated mediation relationship are weaker under a dynamic environment than a stable environment.Research limitations/implicationsAs research reveals, ED moderates the studied model differently, and it raises questions on applicability of western theories, scales and their relationship in the South Asian context. Besides this, it has few limitations, which also present opportunities for future research.Practical implicationsThe findings of this research will be significant to entrepreneurs, educators and policymakers for better understanding about study variables, to use as consulting options as well as to prepare effective policies for entrepreneurship development.Originality/valueThis study is perhaps the first study that examines the complex moderated mediation model in the context of minimal work on EL‒BP relationship and facilitates more sophisticated understanding about their relationships as well as shows variables’ and model’s generalizability in the eastern context.
Strategic impact of retail 4.0 on retailers’ performance in Malaysia
Authors: Sakrabani Poorni , Teoh Ai Ping , Amran Azlan 
Published: October 2019

Purpose
The Malaysian retail industry, which contributes toward almost 45 per cent of the country's Gross Domestic Product (GDP) is on a downward trend. As such, the main purpose of this study is to improve the performance of the Malaysian retail industry through the incorporation of Industry 4.0 technologies. The incorporation of Industry 4.0 technologies in the retail industry has led to the emergence of Retail 4.0 which can also be defined as omni-channel retailing.

Design/methodology/approach
The adoption of Retail 4.0, which is a combination of omni-channel retailing and also novel technologies, has been proven to improve the performance of retailers in many countries. As such, the authors have given suggestions on how Retail 4.0 can be incorporated by Malaysian retailers for the betterment of the Malaysian retail industry.

Findings
Problems faced by retailers these days are boring `brick and mortar' stores, out of stock (OOS) issues, price discrepancy and long queues. Retail 4.0 has enabled retailers to overcome these problems by creating novel shopping experiences, better inventory management, and improved operational efficiency and also more informed decision making in real time.

Limitations
The incorporation of Industry 4.0 technologies in Malaysia is still in the infancy stage. As such, skilled professionals need to be brought in to help implement these technologies in the retail industry.

Practical implications
Omni-channel retailing and the usage of various technologies by `brick and mortar' stores is very appealing to Malaysia's Gen Y and Gen Z who make up 67 per cent of the country's population. The spending power of this young generation can help to boost the performance of the Malaysian retail industry.

Originality/value
To date, no known study has been done on the impact of Retail 4.0 on Malaysian retailers. The results of this study will be very valuable to managers who are keen to improve the performance of their respective retail channels.
Multi-ethnic Macao: from global village to migrant metropolis
Authors: Clayton Cathryn H. 
Published: October 2019

Purpose
In the past 20 years, Macao has experienced phenomenal economic growth driven by the liberalization of its casino sector. This growth has been enabled by massive influxes of foreign capital and migrant labor that have dramatically altered the city’s ethnic landscape. In this paper, the author examines the demographic changes Macao has experienced as a result of the casino boom, and situates the city’s current economic growth and ethnic diversification within its long history as a multi-ethnic city.

Design/methodology/approach
Building on Nancy Foner’s notion of “contexts of settlement,” the study draws on census materials, policy statements, newspaper articles and ethnographic materials to examine how changing ideologies of globalization help shape the categories through which ethnic diversity itself is conceptualized.

Findings
The paper has three main findings. First, despite the Macao government’s multicultural rhetoric, its labor and residency policies that prevent migrant workers from settling in Macao may paradoxically serve to maintain the ethnic status quo ante. Second, the new contexts of settlement engendered by Macao’s casino globalization may be amplifying fissures within the ethnic category “Chinese.” And third, discourses of globalization, regulations on immigration, and classificatory systems governing ethnic diversity that were instituted under Portuguese rule have both helped shape these new contexts and been reworked in the process.

Originality/value
As the processes of urbanization, economic integration and transnational migration continue to accelerate throughout East Asia, the goal of creating inclusive, equitable multi-ethnic urban societies will require closer examination of the relationship between particular modes and ideologies of “global” engagement, patterns of and policies toward migration and the concepts and categories through which diversity is measured. This approach to understanding multi-ethnic Macao may serve as an example.
Effect of high performance work practices on service innovative behavior
Authors: Jaiswal Deepakshi , Tyagi Akansha 
Published: October 2019

Purpose
This study aims to provide a holistic model for high performance work practices (HPWPs), work engagement (WE), job autonomy (JA) and service innovative behavior (SIB) of employees in hotel industry, taking social exchange theory as the base of the study. The present study examined the effect of HPWPs on hotel employees’ SIB, mediated by WE. This study further examined the moderating role of JA on the relationship between WE and SIB.

Design/methodology/approach
The study was conducted in both the Garhwal and Kumaon Himalayan regions, Uttarakhand state, India. Using convenience sampling method and standardized questionnaire, data were collected from 384 employees working in 32 hotels and relationships were tested using Hayes’ method of regression analysis.

Findings
The findings of the study revealed that WE mediated the relationship between HPWPs and SIB. Furthermore, it was observed that JA acted as a moderator between WE and SIB.

Research limitations/implications
The responses were collected from the hotels of Uttarakhand region only, so the future studies may be carried out in other industries such as banking, automobile, IT, call centers, etc., as well as in some other region also.

Originality/value
The present study has made some crucial contributions to the existing literature and knowledge base. The study of different variables has been tested in western countries, but this integrated model is the first of its kind, which was tested in Indian context, i.e. Indian hotel employees, especially in Uttarakhand, India, that has completely different work settings/environment as compared to the western countries.
Using hierarchical joint models to study reproductive interactions in plant communities
Authors: Opedal Øystein H. , Hegland Stein J. 
Published: October 2019

Abstract

Pollinator‐mediated reproductive interactions among co‐flowering plant species are prime examples of how species interactions may affect fitness and community assembly. Despite considerable interest in these issues, statistical methods for assessing signal of reproductive interactions in observational data on co‐flowering species are currently lacking.

We propose a flexible method for quantifying potential reproductive interactions among co‐flowering plant species using the hierarchical latent‐variable joint models implemented in the Hierarchical Modelling of Species Communities (HMSC) framework. The method accommodates any measure of reproductive success, including pollinator visitation, stigma pollen loads, and seed set. We demonstrate the method by analysing a dataset on bumblebee visitation to a set of co‐flowering plant species in a species‐rich meadow in Norway, and provide R tutorials for this and additional data types.

The example analysis revealed both positive and negative effects of heterospecific flower abundances on visitation to co‐flowering species, which we interpret as potential reproductive interactions.

Synthesis. Hierarchical joint models provide a flexible approach to analysing patterns of covariation in the reproductive success of co‐flowering species, thus identifying potential species interactions. Important strengths include explicit consideration of community‐level effects and the assessment of residual fitness correlations after controlling for covariates such as flower abundances and phenotypic traits, yielding more complete insights into pollinator‐mediated reproductive interactions.
Effects of elevated CO2 on Stipa baicalensis photosynthesis depend on precipitation and growth phase
Authors: Wang Hui , Zhou Guangsheng , Jiang Yanling , Shi Yaohui , Xu Zhenzhu 
Published: October 2019

AbstractElevated atmospheric CO2 concentration and simultaneous precipitation change affect plant physiology and growth either directly or indirectly. The main objective of this study was to investigate the effects of elevated CO2 and precipitation change, alone or in combination, on photosynthesis and growth in Stipa baicalensis under differential growth phases. Elevated CO2 showed a consistently significant increase in net photosynthesis rate (Anet), water‐use efficiency (WUE), leaf area and biomass. However, elevated CO2 did not mitigate the negative effects of severe drought stress. Increase of Anet under elevated CO2 attributed to Ci in the early growth phase, but WUE and Rubisco carboxylation (Vcmax) was the main inductor in the later growth phase. Effects of elevated CO2 on S. baicalensis were closely associated with precipitation conditions, and the influence on photosynthetic capacity was also related to the growth phase. Drought significantly reduced Anet in June and August, increased WUE in June but did not show effect in August. Precipitation enhancement was beneficial to leaf area and biomass accumulation. Elevated CO2 and enhanced precipitation in combination promoted Anet by 158% and 93.4% in June and August, respectively; moreover, their interaction increased the total biomass by 44.4%. Our results suggested that the elevated CO2 concentration in the future might be beneficial to the growth of S. baicalensis, but elevated CO2 influence on S. baicalensis might strongly depend on precipitation conditions and the growth phase.
The short‐term effects of the earned income tax credit on health care expenditures among US adults
Authors: Hamad Rita , Niedzwiecki Matthew J. 
Published: October 2019

AbstractObjectiveTo test the hypothesis that the earned income tax credit (EITC)—the largest US poverty alleviation program—affects short‐term health care expenditures among US adults.Data SourcesAdult participants in the 1997‐2012 waves of the US Medical Expenditure Panel Survey (MEPS) (N = 1 282 080).Study DesignWe conducted difference‐in‐differences analyses, comparing health care expenditures among EITC‐eligible adults in February (immediately following EITC refund receipt) with expenditures during other months, using non‐EITC‐eligible individuals to difference out seasonal variation in health care expenditures. Outcomes included total out‐of‐pocket expenditures as well as spending on specific categories such as outpatient visits and inpatient hospitalizations. We conducted subgroup analyses to examine heterogeneity by insurance status.Principal FindingsEITC refund receipt was not associated with short‐term changes in total expenditures, nor any expenditure subcategories. Results were similar by insurance status and robust to numerous alternative specifications.ConclusionsEITC refunds are not associated with short‐term changes in health care expenditures among US adults. This may be because the refund is spent on other expenses, because of income smoothing, or because of similar refund‐related variation in health care expenditures among noneligible adults. Future studies should examine whether other types of income supplementation affect health care expenditures, particularly among individuals in poverty.
Frailty transitions and health care use in Europe
Authors: Sicsic Jonathan , Rapp Thomas 
Published: October 2019

AbstractObjectiveThere is relative consensus that chronic conditions, disability, and time‐to‐death are key drivers of age‐related health care expenditures. In this paper, we analyze the specific impact of frailty transitions on a wide range of health care outcomes comprising hospital, ambulatory care, and dental care use.Data SourceFive regular waves of the SHARE survey collected between 2004 and 2015.Study DesignWe estimate dynamic panel data models on the balanced panel (N = 6078; NT = 30 390 observations). Our models account for various sources of selection into frailty, that is, observed and unobserved time‐varying and time‐invariant characteristics.Principal FindingsWe confirm previous evidence showing that frailty transitions have a statistically significant and positive impact on hospital use. We find new evidence on ambulatory and dental care use. Becoming frail has greater impact on specialist compared to GP visit, and frail elderly are less likely to access dental care.ConclusionsBy preventing transitions toward frailty, policy planners could prevent hospital and ambulatory care uses. Further research is needed to investigate the relationship between frailty and dental care by controlling for reverse causation.
Comparison of Different Analytical Methods for the Determination of Carbon Monoxide in Postmortem Blood
Authors: Zanaboni Moira , Roda Gabriella , Arnoldi Sebastiano , Casagni Eleonora , Gambaro Veniero , Dei Cas Michele 
Published: October 2019

AbstractThe determination of carbon monoxide (CO) and carboxyhemoglobin (COHb) is of utmost importance in forensic toxicology to determine the cause of death in cases of CO poisoning, fire, and explosions. To this end, reliable and updated analytical methods are required. In this paper, four different methods for the determination of carbon monoxide in postmortem blood samples were compared: (i) the spectrophotometric determination of COHb applying the method proposed by Rodkey and modified by Beutler–West, (ii) the spectrophotometric determination of CO using a micro‐diffusion‐based method, (iii) the determination of CO by gas chromatography coupled to a TCD detector, and (iv) the determination of COHb by blood gas analysis. Three postmortem blood samples were analyzed with all methods, and the results were comparable. The applied methodologies showed different features depending on the sensitivity, sample preparation, and volume. The HS‐GC/TCD method in our hand was the most appropriate, on postmortem samples, and versatile to apply. Unfortunately, only a limited number of postmortem blood samples were available for this study due to the rarity of that kind of intoxication in our jurisdiction.
