The new age of customer impatience
Authors: Daugherty Patricia J. , Bolumole Yemisi , Grawe Scott J. 
Published: August 2018

PurposeThe purpose of this paper is to shed light on the body of logistics customer service (LCS) research published in leading logistics journals from 1990 to 2017. Specifically, the paper presents a call to arms for logistics and supply chain researchers to address new and emerging issues impacting customer service in the age of omnichannel and e-commerce retailing.Design/methodology/approachThe authors reviewed academic journals to identify articles focusing on LCS from 1990 through 2017. The authors noted trends in academic research activity/focus and supplemented the findings by examining more recent trends covered in trade publication articles.FindingsThe authors observed a large amount of LCS research in the early 1990s and 2000s, but noticed a substantial decline in coverage within academic journals since the late 2000s while industry continues to give customer service issues even greater attention. The difference between the level of coverage within academic journals and the increased importance firms place on customer service represents a critical gap and opportunity for scholars. This research represents a “call to arms” to address this gap. With particular emphasis on observed customer impatience and escalating requests, within omni- and e-commerce channels of distribution, we suggest greater theoretical insights into customer service strategies and their role in successfully navigating today’s changing logistics service environment are needed.Originality/valueThe review serves as a call for more attention to customer service issues within leading logistics journals. Suggestions for research into new and emerging topics are offered.
The effect of fiber orientation on wear behavior of glass fiber-epoxy filled with particles
Authors: Abdel-Magied Ragab K. , Aly Mohamed F. , Elkhouly Heba I. 
Published: August 2018

Purpose
The fiber orientation is considered one of the important parameters that have an effect on the characteristics of composites. This paper aims to investigate the effect of fiber orientation on the abrasive wear of the glass-epoxy (G-E) composites with different silicon carbide (SiC) filler weights (Wt.%).

Design/methodology/approach
The wear rate of glass fiber reinforced with angle-ply 0º, ±45º and 90º is discussed. The G-E composites with different weights of SiC filler at angle ±45º are considered. Hand lay-up technique was adopted for specimen preparation. The influence of effective parameters such as filler Wt. %, normal load, abrasive size and abrading distance on the wear rate was presented and discussed.

Findings
Experimental tests including pin on disk, micro-hardness and scanning electron microscope were carried out to investigate the composite characteristics.

Originality/value
The experimental results showed that the resistance wear was superior in case of ±45º fiber orientations. A validation of the experimental results using Taguchi approach to verify the optimal wear rate parameters was presented.
Numerical and experimental study on dynamic characteristics of cavitation bubbles
Authors: Cheng Feng , Ji Weixi 
Published: August 2018

Purpose
Cavitation bubbles cannot be avoided in the hydraulic system. Because of instability of flow and variation of water pressure, the jet often occurs in a bubble collapse. This study aims to accurately predict the shape, velocity and time of the resulting jet, so as to inhibit cavitation erosion.

Design/methodology/approach
In the study, a theoretical model of cavitation bubbles in the water has been developed by applying a periodic water film pressure into the Rayleigh–Plesset equation. A fourth-order in time Runge–Kutta scheme is used to obtain an accurate computation of the bubble dynamic characteristics. The behavior of the proposed theory is further simulated in a high-speed photography experiment by using a cavitation bubble test rig. The evolution with time of cavitation bubbles is further obtained.

Findings
A comparison with the available experimental results reveals that the bubble evolution with time has a duration of about 0.3T0, that well predicts the expanding and compressing process of cavitation bubbles. The results also show that the initial bubble radius in the water influences the moving velocity of the bubble wall, whereas the perturbation frequency of the water pressure has less effect on the velocity of the bubble wall.

Originality/value
A theoretical model well predicts dynamic characteristics of cavitation bubbles. The bubble evolution with time has a duration of about 0.3T0, Initial bubble radius influences the velocity of bubble wall. Perturbation frequency has less effect on the velocity of bubble wall.

Authors: Wu Daoyi , Xu Yufu , Yao Lulu , You Tao , Hu Xianguo 
Published: August 2018

PurposeThis paper aims to study the upgradation of the lubricating performance of the renewable base oil , and to study the tribological behavior of graphene oxide (GO) sheets used as lubricating additives in bio-oil for iron/steel contact.Design/methodology/approachA multifunctional end-face tribometer was used to characterize the friction coefficient and wear loss of the tribosystem under different lubricants.FindingsThe experimental results show that GO sheets with small size benefit lubricating effects and the optimal concentration of GO sheets in bio-oil is 0.4-0.6 per cent, which can form a complete lubricating film on the frictional interfaces and obtain a low friction coefficient and wear loss. Higher concentration of GO sheets can result in a significant aggregation of the sheets, reducing the content of the lubricating components in the bio-oil, which results in the increase in friction and wear; at this stage, the main wear pattern was ascribed to adhesive wear.Practical implicationsThese results show a promising prospect of improving the tribological performance of renewable base oil with the introduction of GO sheets as additives.Originality/valueNo literature has covered the tribological behaviour of GO sheets in bio-oil. This study contributes to accelerating the application of bio-oil.
Exploring player behavior and motivations to continue playing Pokémon GO
Authors: Ghazali Ezlika , Mutum Dilip S. , Woon Mei-Yuen 
Published: August 2018

Purpose
The purpose of this paper is to identify the determinants of players’ continuance intentions to play Pokémon GO (PG) and ultimately make in-app purchases, mainly from the perspectives of psychological, social and gaming motivational factors.

Design/methodology/approach
The research model was empirically assessed based on 362 validated responses from current players of PG in Malaysia. Analysis was carried out using the partial least squares path modeling method.

Findings
The results indicated that enjoyment, network externalities, community involvement and the need-to-collect significantly influence players’ continuance intention. Furthermore, the findings reveal that flow and nostalgia have indirect effects on players’ continuance intention, which in turn significantly influences their purchase intention.

Originality/value
This study provides empirical support for an integrated model for understanding the antecedents of the players’ behavioral intentions that incorporates psychological, social and gaming motivational factors in the context of an augmented reality mobile game.
Improving continuing professional development compliance among construction professionals through integrated strategies in South Africa
Authors: Kwofie Titus Ebenezer , Aigbavboa Clinton Ohis , Mpambela Johannes Siabatho 
Published: August 2018

Purpose
A high level of low compliance with continuing professional development (CPD) among construction professionals in developing countries is well acknowledged in existing literature. In spite of several interventions in CPD implementation, reforms and approaches in recent times, there does not seem to be an immediate improvement. This development calls for a re-think among stakeholders to adopt strategies that can yield the best results in uptake. Though several strategies have been proposed to potentially result in CPD uptake and compliance among construction professionals, these possible strategies have not been considered in an integrated manner. This study aims at identifying CPD delivery and implementation strategies that can significantly contribute to compliance and uptake among construction professionals in South Africa.

Design/methodology/approach
Using a quantitative research design and a questionnaire survey, this study sought to identify effective CPD implementation strategies for construction professionals from a plethora of suggested ones that can engender increased uptake and compliance.

Findings
By using multiple regression analysis, the results revealed “flexible e-learning platforms”, “standardisation of CPD model and formats by professional institutions”, “inclusion of CPD in tertiary curriculum to easily understand its importance” and “encouraging practices to have frequent in-house training sessions sharing experiences” as the most significant strategies that are likely to improve CPD uptake and compliance.

Originality/value
Against the backdrop of the need to increase CPD uptake and compliance among professionals through flexible integrated approach comes to the fore the understanding and knowledge of the strategies that can engender CPD uptake and compliance among construction professionals in the construction industry in South Africa.

Corporate governance practices: global convergence and Indian perspective
Authors: Uzma Shigufta Hena 
Published: August 2018

Purpose
This paper aims to study from three perspectives: the developed countries corporate governance (CG) practices, the role of OECD in the global convergence of CG standards and India as an emerging country.

Design/methodology/approach
The paper reviews the various CG codes and regulations enacted in the Indian paradigm with special reference to the Indian Companies Act 2013 (cited as Act 2013).

Findings
The Act 2013 endeavours to provide a governance landscape in India with reforms. The new CG codes comprehensively introduce more accountability, transparency and stringent disclosure requirements. However, these changes are affected by the ownership structure, the level of enforcement and regulatory compliance of CG disclosure practices imposed on companies.

Research limitations/implications
Further research can be carried out in three domains in emerging countries: ownership structure, the effect of legal and regulatory environment and impact of mandatory compliance.

Practical implications
Legal and regulatory environment are notable extent that can effectively govern the CG codes. An increase in the board size, investor protection and gender diversity, with strong governance structure, can enhance the transparency of companies.

Originality/value
The paper examines the prominence of CG norms with the ratification of the Indian Companies Act 2013, which is analogous with global CG policies and regulations.
Modeling Starch Digestograms: Computational Characteristics of Kinetic Models for in vitro Starch Digestion in Food Research
Authors: Nguyen Giang T. , Sopade Peter A. 
Published: August 2018

AbstractStarch digestion is mostly investigated with in vitro techniques, and time‐course measurements are common. These yield digestograms that are modeled by theoretical, semitheoretical, and empirical kinetic equations, many of which are reviewed here. The Duggleby model has Michaelis–Menten functions, and its dependent variable is on both sides of the equation with no apparent parameter for maximum digestible starch (D∞). The Gaouar and Peleg models are equivalent. They predict both the initial digestible starch (D0) and D∞, and an average digestion rate, but they can reveal "biratial" digestions. The first‐order kinetic model exhibits diverse predictabilities and, when linearized, D∞ is sometimes equated to 100 g/100 g dry starch (100%), it yields an average rate of digestion and can predict negative D0. The log of slope (LOS) model is unique in revealing the rapid‐to‐slow digestion rate phenomenon, but without guidelines to identify such. The LOS model does not sometimes use all the digestogram data, can predict D∞ greater than 100%, and returns zero digestion rate for some digestograms. However, some starchy materials exhibit a slow‐to‐rapid digestion rate phenomenon, as demonstrated with an example. The modified first‐order kinetic model uses all the digestogram data with practical constraints (D0 ≥ 0 g/100 g dry starch; D∞ ≤ 100 g/100 g dry starch), describes all digestograms, and yields an average digestion rate, but it can also be used for "biratial" digestions. In addition, the logistic and Weibull models are discussed. Using some published data, the computational characteristics of these commonly used models are presented with objective parameters to guide choices.

Published: August 2018

AimAcute toxicities secondary to (chemo)radiation for head and neck cancer can substantially impact nutritional intake. Nutrition is usually managed by dietitians, although time constraints may limit capacity to sufficiently deal with complex nutritional issues. The aim of the present study was to determine the effectiveness of a nutrition assistant performing screening and intervention of patients in a multidisciplinary head and neck clinic.MethodsA model of care was developed to guide nutrition assistant practice within the clinic, with training provided to nutrition assistants prior to the clinic's implementation. Outcomes, including amount of dietitian time managing high risk patients, weight change over the duration of treatment, timing of initiation of enteral feeding and patient satisfaction were compared with pre‐ and post‐implementation of the nutrition assistant role.ResultsNinety‐one patients were included, 43 pre‐implementation and 48 post‐implementation. Overall, (n = 21, 44%) of patients met criteria for nutrition assistant screening or intervention. Mean weight change between groups was comparable both during (−5.6% vs −4.7%, P = 0.3) and post‐radiotherapy (−6.6% vs −6.49%, P = 0.9). Following implementation of the role significant improvement was found for overall patient satisfaction (4.0 ± 1.1 vs 4.6 ± 0.61, P = 0.03), and the dimensions: patient‐perceived benefit (3.8 ± 0.69 vs 4.4 ± 0.62, P < 0.01) and dietitian/nutrition‐assistant interpersonal skills (3.91 ± 1.1 vs 4.6 ± 0.55, P = 0.02).ConclusionsThe nutrition assistant role resulted in improved patient satisfaction and maintenance of nutritional outcomes demonstrating the effectiveness of this role in supporting the management of head and neck cancer patients within a multidisciplinary treatment clinic.
Estimating the number of contributors to DNA mixtures provides a novel tool for ecology
Authors: Sethi Suresh A. , Larson Wesley , Turnquist Keith , Isermann Dan 
Published: August 2018

Abstract

Mixtures of DNA from multiple contributors present a novel opportunity to count individuals to inform fish and wildlife ecology.

We apply a likelihood‐based framework to estimate the number of contributors to a DNA mixture for ecological applications. We then assess the performance of DNA mixture estimation through a combination of simulation analyses, laboratory testing, and a field trial to estimate fish predation rates from stomach content analysis.

Simulations indicated reasonably sized genetic marker panels could estimate the number of contributors to mixtures comprised of up to 10 individuals, with potential to resolve larger mixtures with additional markers. Mixture estimates demonstrated robustness to common genotyping errors associated with fish and wildlife genetics applications. Laboratory trials demonstrated that DNA combined from multiple yellow perch (Perca flavescens) could be successfully genotyped with a 14‐loci microsatellite panel and led to successful estimation for up to 5‐contributor mixtures. Stomach content analysis with DNA mixtures indicated a 5‐fold increase in estimated predation rates of yellow perch by largemouth bass (Micropterus salmoides) relative to conventional visual assessment of diet contents which can miss partially digested prey items.

DNA mixtures have potential to expand applications of count‐based ecological analyses. Technical challenges in generating genotypes from DNA mixtures may initially limit their use, however, advances in next generation genotyping platforms are anticipated to surmount these obstacles. Chiefly, we envision opportunity for DNA mixtures to advance eDNA analysis beyond presence/absence based inference to enumeration of specimens.
A spatial point process model to estimate individual centres of activity from passive acoustic telemetry data
Authors: Winton Megan V. , Kneebone Jeff , Zemeckis Douglas R. , Fay Gavin 
Published: August 2018

Abstract

Failure to account for time‐varying detection ranges when inferring space use of marine species from passive acoustic telemetry data can bias estimates and result in erroneous biological conclusions. This potential source of bias is widely acknowledged but often ignored in practice due to a lack of available statistical methods.

Here, we describe and apply a spatial point process model for estimating individual centres of activity (COAs) from acoustic telemetry data that can be modified to account for both receiver‐ and time‐specific detection probabilities. We use simulation testing to evaluate the suitability of the proposed models for estimating COAs and compare their performance to that of the popular mean‐weighted COA method for a variety of scenarios. We illustrate how the approach can be applied to correct for variable detection ranges by integrating data from moored test tags and demonstrate how accounting for time‐varying detection probabilities can impact space use estimates by fitting the model to data collected from a black sea bass (Centropristis striata) on a receiver array off the east coast of the United States.

The proposed model reduced bias in COA estimates, particularly when tagged individuals occurred along the periphery of the receiver array. The test tag‐integrated model largely corrected the bias associated with receiver‐ and time‐specific detection probabilities. When applied to the black sea bass detection data, the model revealed fine‐scale movements not apparent when detection ranges were assumed constant.

Spatial management practices for coastal marine species are often based on trends in space use inferred from passive acoustic telemetry data, which can be misinterpreted when factors influencing detection ranges are not accounted for. Our approach provides a general framework for estimating individual COAs that can be modified on a study‐specific basis to ensure resulting patterns of space use reflect a species’ movements and behaviour, rather than variation in receiver detection ranges.
Circulating orexin changes during withdrawal are associated with nicotine craving and risk for smoking relapse
Authors: al'Absi Mustafa , Lemieux Andrine , Hodges James S. , Allen Sharon 
Published: August 2018

AbstractWe examined the extent to which orexin measured during smoking and the early phase of abstinence was related to craving, withdrawal, stress hormones, and risk for smoking relapse in men and women. Considering its role in modulating nicotine‐related reward, we predicted that a reduction in circulating orexin during withdrawal would be associated with increased craving and risk for smoking relapse. Two hundred and eighty five participants provided biological samples and self‐report information to identify predictors of smoking relapse. All participants attended two laboratory sessions, which were before and after a period of required abstinence from smoking. After quitting, participants also attended four weekly sessions to track smoking relapse. Only smokers who relapsed within the follow‐up period exhibited reduced orexin levels during the initial withdrawal period; ACTH, but not craving nor cortisol, increased across the abstinence period for successful abstainers but not for relapsers. Sex differences in orexin and craving or withdrawal associations also emerged. Adding sex, HPA hormones, and self‐reported measures of craving and withdrawal as potential mediators had minimal effects on the above abstinence and orexin effects. These results provide the first evidence that circulating orexin may be a useful marker of risk for relapse; and sex, adrenal hormones, and self‐reported craving and withdrawal were not mediators of this effect. The results point to a promising pathway to investigate objective biological markers for craving and smoking relapse and highlight the complexity of the neurobiology of relapse.
