The dynamic interaction between high-commitment HRM and servant leadership
Authors: McCune Stein Aaron , Ai Min Yan 
Published: June 2019

PurposeBased on social exchange theory and the substitutes for leadership theory, this paper aims to investigate whether an organization’s high-commitment HRM strategy can substitute for the effect of servant leadership in promoting employees’ affective commitment, psychological empowerment and intent to remain with the organization.Design/methodology/approachThis study’s hypotheses were tested with moderation and mediation analyses conducted on a sample of 172 Chinese employees.FindingsThe results show significant negative interaction effects between high-commitment HRM systems and servant leadership, such that high levels of one will reduce the positive effect of the other on affective commitment and psychological empowerment. Further, the effects of high-commitment HRM systems and servant leadership on turnover intentions are mediated through affective commitment and psychological empowerment. Finally, support was found for a mediated moderation model where the negative interaction effect between high-commitment HRM systems and servant leadership on turnover intentions is mediated through affective commitment.Practical implicationsThe results of this study can help practitioners identify alternative means to influence employees’ positive attitudes and work motivation when implementing high-commitment HRM systems is not feasible for the organization.Originality/valueThis study contributes to the leadership literature by providing evidence supporting the substitutes for leadership theory and describing the specific conditions under which this theory is valid, as well as contributing to the HRM literature by examining the dynamic interaction of HRM and leadership.
Effect of celebrity endorsement on telecommunication companies’ reputation
Authors: Zakari Mariama , Dogbe Courage Simon Kofi , Asante Collins 
Published: June 2019

PurposeThe study aims to assess the moderating role of celebrity characteristics in the relationship between celebrity endorsement and telecommunication companies’ reputation.Design/methodology/approachAnalysis of results was based on 700 customers in the telecommunication sector. Confirmatory factor analysis was conducted to check for validity and reliability of the observed items. A hierarchical regression model was estimated to test the various hypotheses set for the study.FindingsThe study finds that celebrity endorsement in itself had no significant effect on the reputation of telecommunication companies. Celebrity attractiveness, likeability and trustworthiness had a direct effect (positive) on the reputation of telecommunication companies and positively moderated the effect of celebrity endorsement on telecommunication company reputation. Celebrity expertise had no direct effect on telecommunication company reputation but positively moderated the effect of celebrity endorsement and telecommunication company reputation.Research limitations/implicationsThis study was purely quantitative. Future study could consider a mixed approach and include senior management members of the telecom firms for an in-depth interview.Practical implicationsIn signing on celebrities as brand ambassadors, management must pay particular attention to celebrity attractiveness, likeability and trustworthiness. This would be more rewarding to the firms.Originality/valueThe study adds to the little empirical knowledge available on celebrity endorsement in sub-Saharan Africa and telecommunication sector in particular.
Stock market, banking sector and economic growth
Authors: Guha Deb Soumya , Mishra Sibanjan , Banerjee Pradip 
Published: June 2019

Purpose
The purpose of this paper is to examine the causal relationship between economic development and financial sector development for 28 countries at different stages of their development. The authors specifically focus on the nature of causality during economic boom and tranquil cycles.

Design/methodology/approach
The study uses quarterly time series panels of 17 developed and 11 emerging countries, during 1993Q1-2014Q4 with each having three sub-panels – full sample, a period of the economic uptrend (UP), and period of the economic downtrend. The authors use a univariate analysis for initial screening followed by panel unit root test, panel co-integration and causality test proposed by Toda–Yamamoto to examine the causal relationship.

Findings
The principal results suggest that for developed economies, there is a causal flow from financial sector to real sector in line with the “supply-leading” hypothesis, whereas for emerging economies, it is from real sector to financial sector, in line with the “demand-following” hypothesis. This overall relationship is strong for both emerging and developed economies during economic boom or UP cycles, but becomes weak during economic downturns or tranquil periods.

Originality/value
This study is different from previous studies on this issue and contributes to the existing literature in a number of ways. First, the focus of this paper revolves around identification of differential patterns in causal flows between real and financial sectors for different economies, across different economic cycles. Second, to present a robust representation of financial sector, the authors consider both banking sector and stock market parameters as the proxy for financial sector development. Third, the authors address the “stock-flow problem” in the measurement of financial variables a typical criticism of some of the previous studies. Finally, the authors use a rich sample size comprising of about 2,500 quarterly observations for each variable, with about 1,500 observations from developed and 1,000 from emerging economies.

Published: June 2019

Purpose
Technological capabilities of manufacturing microelectromechanical system (MEMS) gyroscopes are still insufficient if compared to manufacturing high-efficient gyroscopes and accelerometers. This creates weaknesses in their mechanical structure and restrictions in the measurement accuracy, stability and reliability of MEMS gyroscopes and accelerometers. This paper aims to develop a new architectural solutions for optimization of MEMS gyroscopes and accelerometers and propose a multi-axis MEMS inertial module combining the functions of gyroscope and accelerometer.

Design/methodology/approach
The finite element modeling (FEM) and the modal analysis in FEM are used for sensing, drive and control electrode capacitances of the multi-axis MEMS inertial module with the proposed new architecture. The description is given to its step-by-step process of manufacturing. Algorithms are developed to detect its angular rates and linear acceleration along three Cartesian axes.

Findings
Experimental results are obtained for eigenfrequencies and capacitances of sensing, drive and control electrodes for 50 manufactured prototypes of the silicon electromechanical sensor (SES). For 42 SES prototypes, a good match is observed between the calculated and simulated capacitance values of comb electrodes. Thus, the mean-square deviation is not over 20 per cent. The maximum difference between the calculated and simulated eigenfrequencies in the drive channel of 11 SES prototypes is not over 3 per cent. The same difference is detected for eigenfrequencies in the first sensing channel of 17 SES prototypes.

Originality/value
This study shows a way to design and optimize the structure and theoretical background for the development of the MEMS inertial module combining the functions of gyroscope and accelerometer. The obtained results will improve and expand the manufacturing technology of MEMS gyroscopes and accelerometers.
Can Chipotle compete by delivering “food with integrity”?
Authors: Assenza Pauline , Lewis Michael S. 
Published: June 2019

Research methodology
The case data were obtained from secondary sources including academic, newspaper and periodical sources.

Case overview/synopsis
The Founder of Chipotle Mexican Grill, CEO Steve Ells, was a restaurant innovator credited with creating the fast-casual experience. He believed that food, sourced and prepared responsibly, could help “cultivate a better world.” Unfortunately, he had to step down after a continuing series of food contamination events drove away both investors and customers. In 2018, new CEO Brian Niccol was brought in from Taco Bell to reposition the brand and regain confidence. Was it possible to continue with Chipotle’s mission of “food with integrity” or was another strategy necessary?

Complexity academic level
This case was prepared for an undergraduate strategy course. It can be used to illustrate all the key points in Chapter 1 of a traditional undergraduate strategy textbook. This case would be best placed in the first weeks of the course, as a first case to introduce to students the idea of strategy as a process that continuously assesses and revises strategic directions and decisions. It introduces a discussion of the role of mission, vision and values as part of the strategy process, and addresses the responsibility of leadership to do an ongoing evaluation of a firm’s strategic choices.
Capture and evaluation of innovative ideas in early stages of product development
Authors: Madzík Peter 
Published: June 2019

Purpose
The purpose of this paper is to propose a structured procedure for the capture and evaluation of innovative ideas in the early stages of product development. The procedure is designed to take account of internal and external factors affecting the value of innovative ideas.

Design/methodology/approach
The proposed procedure is based on divergent and convergent approaches to innovation. Ideas are generated and captured using targeted questions and subsequently evaluated using modifications of the Kano model and failure mode and effect analysis (FMEA). Idea evaluation considers four criteria – delight, originality, market share potential and simplicity – which are used to compute an “idea priority number”.

Findings
A case study looking at innovations in swimming goggles verified the validity of the proposed procedure. The procedure also supports fact-based decision making and applies a structured perspective to the innovation process that makes it easier to manage.

Research limitations/implications
The case study made use of a pilot survey in which 32 customers participated. Although the case study was only intended as a demonstration of the method’s use, such a sample size could lead to unreliable results in certain cases.

Originality/value
Applications of standard or expanded FMEA do not add value to a product because the main purpose of the approach is to prevent failure. The proposed inversion of FMEA logic combined with customer view via the Kano model offers a method for the structured analysis of product innovations. No similar approach to the evaluation of innovations has so far appeared in the literature.

Published: June 2019

AbstractBlack rice (Oryza sativa L. indica) is one of the cereal commodities considered to be a source of anthocyanin. One of the obstacles of using anthocyanins as natural food colorants is their low stability. The objective of this study was to determine the effect of natural plants extracts on anthocyanin copigmentation and to study the stability of the encapsulated copigmented anthocyanin during storage under different temperatures and light exposure. Dried bilimbi leaves (BL) and sow thistle leaves (STL) were extracted using ethanol to obtain the crude flavonoid extract that was subsequently purified using solid phase extraction. Both crude (CBL, CSTL) and purified (PBL, PSTL) extract were used as copigment agents with the molar ratio of 1:0.1 to 1:10 at pH 1 and pH 3. The copigmentation effect was evaluated by measuring the wavelength and absorbance shifts at wavelengths of 500 to 600 nm. The stability of the dried anthocyanin powder was evaluated under different temperatures and light exposure for up to 4 weeks. Anthocyanin was successfully copigmented with BL and STL extracts showing a wavelength shift and absorbance increase at pH 1 and pH 3. Purification of BL enhanced the hyperchromic effect more than that of the crude form, in contrast to the STL. Meanwhile, the retention of absorbance (%) for encapsulated copigmented anthocyanin samples was within 74% to 83% at the end of the storage period.Practical ApplicationNatural food pigment such as anthocyanin obtained from plant extract usually shows very limited stability under various processing conditions. This study shows that color stability of anthocyanin extracted from black rice can be improved by copigmentation with flavonoids extracted from particular plants. Encapsulation of the copigmented anthocyanin could further enhance its color stability. The availability of encapsulated and copigmented anthocyanins with improved color stability is expected to provide more alternatives for especially the beverage industry to choose suitable natural colorant for their products.
Effect of preoperative fluid therapy on hemodynamic stability during anesthesia induction, a randomized study
Authors: Myrberg Tomi , Lindelöf Linnea , Hultin Magnus 
Published: June 2019

BackgroundPreserving perfusion pressure during anesthesia induction is crucial. Standardized anesthesia methods, alert fluid therapy and vasoactive drugs may help maintain adequate hemodynamic conditions throughout the induction procedure. In this randomized study, we hypothesized that a pre‐operative volume bolus based on lean body weight would decrease the incidence of significant blood pressure drops (BPD) after induction with target‐controlled infusion (TCI) or rapid sequence induction (RSI).MethodsEighty individuals scheduled for non‐cardiac surgery were randomized to either a pre‐operative colloid fluid bolus of 6 ml kg−1 lean body weight or no bolus, and then anesthetized by means of TCI or RSI. The main outcome measure was blood pressure drops below the mean arterial pressure 65 mm Hg during the first 20 minutes after anesthesia induction. ClinicalTrials.com Identifier: NCT03394833.ResultsPre‐operative fluid therapy decreased the incidence of BPDs fivefold, from 23 of 40 (57.5%) individuals without fluids to 5 of 40 (12.5%) with fluid management, P < .001. The mean BPD was greater in the groups without pre‐operative fluids compared to the groups with fluid management; 53 ± 18 mm Hg vs 43 ± 14 mm Hg, P = .007. The overall mean volume of pre‐operative fluid bolus infused was 387 ± 52 ml. There was no difference in hemodynamic stability between TCI and RSI. No correlation was shown between incidence of BPDs and increasing age, medication, hypertension, diabetes, renal failure, or low physical capacity.ConclusionsPre‐operative fluid bolus decreased the incidence of significant blood pressure drops during TCI and RSI induction of general anesthesia.

BackgroundSelf‐Rating of the Effects of Alcohol (SRE) measures level of response to ethanol (EtOH) in humans. Interestingly, there is a positive relationship between the SRE and risk for abusing alcohol, suggesting mechanistic connections between SRE and alcohol abuse.MethodsTo identify candidate genes with a role in SRE and alcohol‐related behavior more generally, we coupled human genetic analyses with studies in Drosophila melanogaster. We first performed a gene‐based analysis of Genomewide association studies (GWAS) summary statistics for SRE in the Avon Longitudinal Study of Parents and Children sample. Based on prior findings in humans, orthology to fly genes, and the availability of genetic reagents, we selected a subset of these genes for studies on EtOH behavior in Drosophila.ResultsWe found 37 genes with nominal associations in our SRE GWAS. We explored the role of 6 orthologous genes in Drosophila EtOH sedation and rapid tolerance. We found that the transcription factor Mef2 is required for normal EtOH sedation in flies. Pan‐neuronal expression of 2 independent Mef2 RNAi transgenes significantly reduced Mef2 expression and made flies resistant to EtOH sedation. Additionally, flies with multiple independent mutant alleles of Mef2 were also resistant to EtOH sedation, confirming a role for Mef2 in this behavior. Altered expression of Mef2 did not change EtOH rapid tolerance or cause a net change in internal EtOH concentrations.ConclusionsOur studies indicate that MEF2B influences SRE in humans and that Mef2 impacts EtOH sedation in Drosophila.

AbstractElectroacupuncture (EA) has been developed on the basis of traditional Chinese acupuncture. EA can suppress craving in opioid addicts and opioid‐seeking responses in rodents. However, the molecular mechanism of EA on the rewarding properties of morphine and craving responses is not known. Here, we have applied a conditioned place preference paradigm in mice to measure morphine‐induced rewarding effects along with EA treatment. Circular RNAs (circRNAs) can function as micro RNA (miRNA) sponges to effectively regulate gene expression levels. CircRNA profiling within the nucleus accumbens (NAc) was performed in EA‐treated and sham‐treated mice. Following RNAseq, data were analyzed by gene ontology (GO) and Kyoto Encyclopedia Genes and Genomes (KEGG) tools. We identified 112 significantly differentially expressed circRNAs, including 51 that were up‐regulated and 61 that were down‐regulated. Our bioinformatics analyses show that these differentially expressed circRNAs map into pathways that are mainly involved with renin secretion and the cGMP‐PKG signaling. We further constructed a circRNA‐miRNA network that predicts the potential roles of the differentially expressed circRNAs and the interaction of circRNAs with miRNAs. Our secondary sequencing and bioinformatics analysis in the NAc after EA treatment on morphine‐induced CPP provides putative novel targets on molecular mechanisms involved in morphine reinforcement and possibly craving.

AbstractPreclinical data indicate that selective kappa opioid receptor antagonists reduce nicotine self‐administration and withdrawal symptoms. The aim of the current study was to determine whether treatment with CERC‐501, an orally available, potent, and selective kappa opioid receptor antagonist, could alleviate nicotine withdrawal and craving and mitigate mood alterations associated with nicotine withdrawal in humans. Healthy, adult cigarette smokers were enrolled into this randomized, multisite, double‐blind, placebo‐controlled, crossover study. Participants completed two 8‐day treatment phases during which they received either CERC‐501 (15 mg, p.o., once daily) or placebo. On the seventh day of each dosing phase, participants were admitted as inpatients for an 18‐hour cigarette abstinence period followed by experimental testing. The primary outcome measures were (a) performance on the McKee Smoking Lapse test (ie, latency to smoke in exchange for money) and (b) number of cigarettes self‐administered during a 60‐minute ad lib smoking period. Other outcomes included measures of craving, mood, anxiety, nicotine withdrawal, and subjective effects of cigarette smoking. A total of 71 participants who smoked an average of approximately 23 cigarettes per day were enrolled, and 56 subjects completed the study. CERC‐501 was well tolerated, but it did not significantly alter the latency to start smoking (CERC‐501: 16.5 min vs placebo: 17.7 min) or the number of cigarettes smoked (CERC‐501: 3.3 cigarettes vs placebo: 3.1 cigarettes). Compared with placebo, CERC‐501 also did not affect cigarette craving, mood, anxiety, nicotine withdrawal, or subjective effects of smoking. These findings do not support a role for CERC‐501 in the treatment of nicotine use disorder.
The present crisis in male reproductive health: an urgent need for a political, social, and research roadmap
Authors: De Jonge C. , Barratt C.L. R. 
Published: June 2019

AbstractBackgroundThere is a global crisis in male reproductive health. Evidence comes from globally declining sperm counts and increasing male reproductive system abnormalities, such as cryptorchidism, germ cell tumors, and onset of puberty. Male factor infertility occurs in ~40% of couples experiencing infertility. Data demonstrate an association between male infertility and overall health. Associated significant health conditions include diabetes mellitus, metabolic disorders, and cardiovascular disease. Adding to the complexity is that men typically do not seek health care unless there is acute medical need or, as in the case of the infertile couple, the male goes for a reproductive examination and semen analysis. However, 25% of the time a reproductive health examination does not occur. Couples are increasingly utilizing IVF at more advanced ages, and advanced paternal age is associated with increased risk for (i) adverse perinatal outcomes for both offspring and mother; (ii) early child mortality, cancer, and mental health issues. In addition to age, paternal lifestyle factors, such as obesity and smoking, impact not only the male fertility but also the offspring wellness.ObjectivesThe purpose of this paper was (i) to spotlight emerging and concerning data on male reproductive health, the relationship(s) between male reproductive and somatic health, and the heritable conditions father can pass to offspring, and (ii) to present a strategic roadmap with the goals of increasing (a) the awareness of men and society on the aforementioned, (b) the participation of men in healthcare seeking, and (c) advocacy to invigorate policy and funding agencies to support increased research into male reproductive biology.ConclusionsThe Male Reproductive Health Initiative (MRHI) is a newly established and rapidly growing global consortium of key opinion leaders in research, medicine, funding and policy agencies, and patient support groups that are moving forward the significant task of accomplishing the goals of the strategic roadmap.
