A bundling sales strategy for a two-stage supply chain based on the complementarity elasticity of imperfect complementary products
Authors: Liu Yong , Wang Xiaoying , Ren Wenwen 
Published: March 2020

Purpose
This paper attempts to analyze the relationship between the complementarity degrees of imperfect complementary products and sales strategies and give appropriate sales strategies for a two-stage supply chain.

Design/methodology/approach
With respect to two-stage supply chain consisting of two manufacturers who produce imperfect complementary products and one retailer who sells the products, aiming at bundling sales strategy, the authors define complementarity elasticity of products and use it to measure the degree of complementary between two products. Based on Stackelberg game and cooperation, the authors analyze the relationship between the complementarity degrees of imperfect complementary products and appropriate sales strategies.

Findings
As the impact of complementarity degree on sales strategy decision-making is better, the authors can pinpoint out which sales decision-making is optimal and which bundling sales strategy is the best for a two-stage supply chain. Considering that the degree of complementarity has a significant impact on the product sales strategy, the authors can point out which sales decision-making is optimal, that is, which bundled sales strategy is the optimal in the secondary supply chain of selling complementary products.

Practical implications
An innovative bundling can expand the sales of existing products and new products. It helps a retailer transcend and defeat competitors by reducing marketing expenses while increasing profits. Proper use of bundling can improve consumers utility and create an overall positive effect for both the enterprises and consumer.

Originality/value
The research can help some retailers to make many appropriate bundling sales strategies.
Drivers and inhibitors of the compromise effect – a conceptual overview
Authors: Schliwa Victor Andrej , Ciornea Raluca 
Published: March 2020

Purpose
This paper aims to review numerous known drivers and antecedents of compromise behavior, proposing a basic categorization of the various contributions. This is done with the goal to integrate drivers and antecedents, previously largely discussed in isolation of one another, into a single conceptual model. This sheds light on the issue of previously overstated or understated relevance of individual drivers. The picture is completed by the proposition of new potential drivers of the compromise effect like lay rationalism and approval motivation.

Design/methodology/approach
The paper takes a conceptual approach in reflecting on prior findings from the field of compromise effect research and adjacent fields to develop a number of propositions aggregated in a conceptual model.

Findings
A number of previously overlooked, but potentially highly relevant interaction effects among known drivers of the compromise effect are proposed along with the proposition of several new drivers.

Originality/value
This conceptual paper offers a novel, broadly applicable categorization of compromise effect research. Further, it seems to be the first paper dedicated to an extensive review of established drivers of the compromise effect to examine the interdependence and possible interaction effects and of those drivers. Additionally, completely new potentially relevant drivers are discussed in detail and integrated into a conceptual model.
At what level of corruption does economic growth decrease?
Authors: Trabelsi Mohamed Ali , Trabelsi Hédi 
Published: March 2020

PurposeThe purpose of this study is to examine the impact of corruption on economic growth by testing the hypothesis that the relationship between these two variables is nonlinear and by assessing the veracity of the assumption that corruption is always detrimental to economic growth. Several cross-country studies have treated this question but the findings are not universally robust.Design/methodology/approachIn this paper, a panel data analysis has been used to examine 88 countries over the 1984-2011 period. A cross-sectional framework is used in which growth rate and the International Country Risk Guide (ICRG) index are observed only once for each country.FindingsThe findings indicate that beyond an optimal threshold, both high and low corruption levels can decrease economic growth. Under this optimal threshold, a moderate level of corruption, defined by the point of reversal of the curve of the marginal corruption effect on growth, could have advantages for economic growth.Originality/valueThis paper shows that the threshold would be a corruption level between 2.5 and 3, which represents the “acceptable corruption level”. This result is conforming to one of the ten principles of economics: “Rational people think at the marginal change”. This threshold represents the point where the marginal benefits of corruption are equal to marginal costs incurred by corruption. Conversely, lack of corruption may be a mechanism that slows down growth.
Halal certification, the inadequacy of its adoption, modelling and strategising the efforts
Authors: Haleem Abid , Khan Mohd Imran , Khan Shahbaz 
Published: March 2020

Purpose
Need for effective adoption of halal certification through assessment and accreditation (HCAA) is imperative for the higher level of customer satisfaction. To achieve this, all stakeholders need to be involved in developing the policy. Thus, this study aims to identify barriers to the adoption of HCAA and analyses through structural model of interrelated barriers

Design/methodology/approach
The structural and hierarchical model of barriers to the adoption of HCAA is developed after extensive systematic literature survey along with opinions from various types of experts. Interpretive structural modelling is identified as the appropriate tool in making this model, which is further analysed using MICMAC (Matriced’ Impacts croises-multipication applique’ and classment). Corresponding issues for every barrier as identified may help in further developing the action plan for each stakeholder. Objectives and action plan for various stakeholders were evolved and provided.

Findings
The significant finding indicates to developing a globally accepted halal certifying organisation, as to contain the mislabelling, and this further needs extensive government and customer support. The customer needs to be more aware of the proper idea of halal. Therefore, to succeed, the industry needs to develop a brand identity with a distinct/unique/clear marketing message, not just certifying products/services as halal.

Originality/value
Specific direction for different stakeholders has been derived along with academic finding for researchers and to further develop the action plan.
Job stress and its impact on health of employees: a study among officers and supervisors
Authors: Sidhu Amanpreet Kaur , Singh Harwinder , Virdi Sandeep Singh , Kumar Raman 
Published: March 2020

PurposeThe purpose of this research paper is to identify the sources of job stress and their impact on health of employees.Design/methodology/approachA total of 650 employees of power sector in Punjab (India) responded to the survey. Exploratory factor analysis and ANOVA were performed. Further, post hoc was conducted to find out which variable differs significantly.FindingsThe findings indicates that five parameters, namely workload, working environment, concentration, positivity and future perspective are the factors that are responsible to create stress in employees. There is great impact on health as “frequency of visit to a doctor” and “numbers of diseases” they have are high and “employee's time spared for exercise” is less.Research limitations/implicationsSince the survey was conducted only in power sector, it is difficult to generalize the results. However, the findings from this study will provide the factors that cause job stress and how they impact on health of employees.Practical implicationsThe result indicates the impact of job stress on health of employees in power sector. Current research suggests that job stressors should be treated timely to minimize the impact of job stress.Originality/valueWhile previous research has focused on the effect of stress on health, the present study provides evidence of the relationship between the sources of job stress and health, particularly in power sector in Punjab. This study would be contributing to the existing literature in Indian context.
Talent quotient: development and validation of a measurement scale
Authors: Yogalakshmi J.A. , Supriya M.V. 
Published: March 2020

PurposeThe aim of the current study was to develop and validate a measure for identifying talent in the workplace. This is a gap long identified by researchers in this field.Design/methodology/approachHinkins methodology was adopted for the establishment of a psychometrically sound measure. A 16-item scale for assessing the construct was developed. The reliability and validity were established by analyzing content adequacy, convergent validity, divergent validity and external validity. Primary data were collected from employees signaled as talent by their organization.FindingsThe study yielded a six-factor structure scale for the construct. These factors accounted for 66.8 percent of observed variance. All six dimensions, namely, calling orientation, critical insight, continuous learning, collaboration, cohesiveness and challenge drive established acceptable reliability and validity.Social implicationsThe research provides a precise definition of the talent construct. Identification and retention of individuals with a high talent quotient is a critical challenge to organizations. Identifying talent is made possible through this measurement scale.Originality/valueThis research made an attempt to develop a reliable and valid measurement scale for the talent construct. The scale provides a precise definition of the talent construct. This simple sound scale could be useful at both the individual and organizational levels. It helps individuals to identify and focus on critical areas for achieving talent status. Organizations benefit through better human resource management practice. Identification and retention of talent are essential to career management. Overall, it also satisfies the urgent need in talent management research for a clear definition of the talent construct.
Risk investment decisions within the deterministic equivalent income model
Authors: Song Yan , Li Xin Yun , Li Yi , Hong Xianpei 
Published: March 2020

Purpose
The purpose of this paper is to establish a deterministic equivalent income model (DEIM) based on the risk cost (RC) and risk aversion of investors. The model fully considers both subjective and objective factors that affect risk investment and reasonably evaluates risk investment schemes to choose the correct investment scheme and gain greater investment returns.

Design/methodology/approach
The utility function is used to measure the extent to which an investor is satisfied by investment returns in various scenarios. Risk aversion expresses subjective attitude of investors to risk. RC represents risk loss in currency. This methodology is based on risk aversion function, utility function and RC theory to establish DEIM.

Findings
This study shows that investors with different risk preferences have different certainty equivalent returns (CER), so their choices of investment options change accordingly.

Practical implications
In this paper, the authors use DEIM to test an investment case and conclude that the CER and investment scheme both change with different risk preferences. At the same time, case analysis shows that DEIM is reasonable and stable when evaluating risk investment schemes.

Originality/value
In this study, the authors innovate by introducing both the RC and risk aversion degree into risk investment schemes evaluation and by deriving a utility function from the absolute risk aversion function to build a utility decision matrix and establish DEIM. The model combines the subjective and objective factors that influence risk investment decisions.
Towards understanding key enablers to green humanitarian supply chain management practices
Authors: Bag Surajit , Luthra Sunil , Venkatesh V.G. , Yadav Gunjan 
Published: March 2020

PurposeHumanitarian supply chains (HSCs) by their very nature require urgent reaction to unforeseeable needs, making it difficult to properly plan for the support of actual demands. As such, integrating sustainability into traditional HSC practices continues to present a challenge to governments, nongovernmental organizations (NGOs) and other humanitarian-related agencies. This study focuses on identifying and categorizing the leading enablers to green humanitarian supply chains (GHSCs) and proposes a model for improving the responsiveness based upon a fuzzy total interpretive structural modelling approach.Design/methodology/approachTotal interpretive structural modelling (TISM) uses group decision-making to identify contextual relationships among each pair of enablers and elucidates the nature of each underlying relationship. The fuzzy TISM shows the level of strength (very high influence, high influence, low influence and very low influence) of each enabler in relation to other enablers, which can help to inform management decision-making.FindingsGHSC management requires strategic planning of inventory and logistics management. The importance of collaborative relationship building with HSC partners for developing capability and the effective use of available resources are keys to success. These improved relationships also help to promote postponement and similar speculation-based logistics strategies, as well as advanced purchasing and pre-positioning strategies. Finally, the speed and quality of response is found to be the top enabler in GHSC management.Research limitations/implicationsOne noted shortcoming of the chosen research method is its reliance on subjective expert judgement. However, collecting judgements is at the basis of many research methods, and the research team took utmost care throughout the research process to allay biases. Future empirical research can further examine the relationships suggested herein. Managers can use the model developed in this research to consider impactful ways to design and execute sustainable HSCs.Originality/valueTo the best of the authors' knowledge, this is a novel attempt to identify enablers to GHSC management. Secondly, the research team has used an advanced methodology (fuzzy TISM) to develop the contextual inter-relationships among the enablers which has not been used earlier in this direction before and thus advances the GHSC literature.
Pricing decisions and subsidy preference of government with traditional and green products
Authors: Zhen Xueping , Xu Shuangshuang , Shi Dan , Liu Fangjun 
Published: March 2020

PurposeThis study aims to explore the government’s subsidy preference and pricing decisions of a manufacturer who produces traditional and green product simultaneously under different government subsidy policies.Design/methodology/approachThe authors establish a model consisting of a government, a set of heterogeneous consumers and a manufacturer. Three government subsidy policies are investigated without government subsidy (NS), government subsidy to consumer (CS) and government subsidy to the manufacturer (MS).FindingsThe results show that the government subsidy can increase both the green product’s demand and the manufacturer’s profit. The subsidy level and government’s utility under the CS policy are equal to those under the MS policy. Furthermore, if the government’s subsidy level is exogenous, there exists a Pareto improvement region when social welfare for unit greenness level is high. That is, if the government’s subsidy level under the CS policy is higher than that under the MS policy, both government and manufacturer prefer the CS policy; otherwise, they prefer the MS policy.Research limitations/implicationsThis paper considers the market where there is a monopoly green manufacturer and a government that only provides subsidy policy. In fact, competition from traditional manufacturers and carbon taxes are also worth exploring in future research.Practical implicationsThis study provides some suggestions for government subsidy and provides guidance for the manufacturer’s pricing decisions under different government subsidy policies.Originality/valueThis paper is the first to compare government subsidy to consumer with a government subsidy to the manufacturer and investigate the pricing decisions of a manufacturer who produces traditional and green product simultaneously by considering an endogenous subsidy level of government.
Unpacking transformational leadership: dimensional analysis with psychological empowerment
Authors: Minai Mohammad Haris , Jauhari Hemang , Kumar Manish , Singh Shailendra 
Published: March 2020

PurposeScholarly studies have criticized transformational leadership (TFL) for its lack of conceptual clarity and inadequate operationalization. This study endeavors to do a detailed examination of the dimensions of the construct to address the lack of conceptual clarity. Further, with respect to concerns regarding operationalization, the study does an exploratory evaluation of reconceptualized TFL's relationship with psychological empowerment, a construct through which TFL mostly has its beneficial outcomes.Design/methodology/approachRespondents (n = 335) from an Indian information technology (IT) services organization report on their psychological empowerment and the transformational behaviors of their supervisors using temporally separated (15 days) online questionnaires.FindingsAs expected, the dimensions of transformational leadership are not equally salient in influencing psychological empowerment; however, they explain variance in all dimensions of psychological empowerment. Visioning relates to meaning and impact; inspirational communication relates to all dimensions of empowerment; personal recognition relates to impact and competence; finally, intellectual stimulation relates to self-determination. Contrary to expectations, however, data did not support the relationship of intellectual stimulation and supportive leadership on competence.Research limitations/implicationsData collected from a single organization limit the claims of generalizability, and the use of a cross-sectional design prevents claims of causality. Given the significant variation in relational properties of individual dimensions, scholars can use dimensions of TFL, and therefore theorizing with these is possible.Originality/valueThis paper provides additional support for the unpacking of TFL, by hypothesizing and demonstrating the dimensional relationships between TFL and psychological empowerment.

Authors: Okwu Modestus Okechukwu , Samuel Olusegun D. , Otanocha Omonigho B. , Balogun Promise P. , Tega Ogugu J. , Ojo Ebenezer 
Published: March 2020

Purpose
A novel cost-effective bio-digester was explored to convert biological waste into useful clean energy. The bioreactor was aimed to anaerobically digest locally sourced cow dung and chicken droppings.

Design/methodology/approach
The design consideration is a batch horizontal 267 L digester made from cast iron with centrally positioned four-impeller shaft to enhance mixing. The system operated with a retention time of 63 days and a substrate (cow dung and poultry waste) ratio of 1:2 and water substrate ratio of 1:0.5 in the gasholder system. The purification, compression and performance evaluation of the generated biogas were also conducted.

Findings
The total volume of gas produced for each substrate compositions designed over 14 days ranges between 49.34 and 52.91 mL/day. The optimal value of 52.45 ml using cow dung and poultry waste (w/w) 20:80 was obtained. The average ambient temperatures during the study were within the mesophilic range of 20-40°C. The pH values were stable and always in the optimal range of 6.5-8.0. The reductions in moisture content, ash content, total solids and volatile solids were from 80.50-0.20 per cent, 39.60-14 per cent, 18.50-5.90 per cent and 11.60-4.90 per cent, respectively.

Originality/value
The developed digester is cost-effective and would help minimize solid waste disposal. The estimated methane contents of the gas from cow dung and chicken waste after scrubbing were found to be 71.95 per cent and could be harnessed in solving the energy crisis in the developing nations.
Experimental N and P additions relieve stoichiometric constraints on organic matter flows through five stream food webs
Authors: Demi Lee M. , Benstead Jonathan P. , Rosemond Amy D. , Maerz John C. 
Published: March 2020

Abstract

Human activities have dramatically altered global patterns of nitrogen (N) and phosphorus (P) availability. This pervasive nutrient pollution is changing basal resource quality in food webs, thereby affecting rates of biological productivity and the pathways of energy and material flow to higher trophic levels.

Here, we investigate how the stoichiometric quality of basal resources modulates patterns of material flow through food webs by characterizing the effects of experimental N and P enrichment on the trophic basis of macroinvertebrate production and flows of dominant food resources to consumers in five detritus‐based stream food webs.

After a pre‐treatment year, each stream received N and P at different concentrations for 2 years, resulting in a unique dissolved N:P ratio (target range from 128:1 to 2:1) for each stream. We combined estimates of secondary production and gut contents analysis to calculate rates of material flow from basal resources to macroinvertebrate consumers in all five streams, during all 3 years of study.

Nutrient enrichment resulted in a 1.5× increase in basal resource flows to primary consumers, with the greatest increases from biofilms and wood. Flows of most basal resources were negatively related to resource C:P, indicating widespread P limitation in these detritus‐based food webs. Nutrient enrichment resulted in a greater proportion of leaf litter, the dominant resource flow‐pathway, being consumed by macroinvertebrates, with that proportion increasing with decreasing leaf litter C:P. However, the increase in efficiency with which basal resources were channelled into metazoan food webs was not propagated to macroinvertebrate predators, as flows of prey did not systematically increase following enrichment and were unrelated to basal resource flows.

This study suggests that ongoing global increases in N and P supply will increase organic matter flows to metazoan food webs in detritus‐based ecosystems by reducing stoichiometric constraints at basal trophic levels. However, the extent to which those flows are propagated to the highest trophic levels likely depends on responses of individual prey taxa and their relative susceptibility to predation.
