Authors: Ali Sadia Samar , Kaur Rajbir 
Published: January 2018

PurposeThe purpose of this paper is to evaluate the satisfaction level of customers using third party logistics (3PL) services in the Indian capital region and its surrounding areas. The American Customer Satisfaction Index (ACSI) model is used as a framework to identify the major drivers of satisfaction and areas requiring immediate attention for provision of better services.Design/methodology/approachPresent study includes an exhaustive review of literature for the identification of enablers for this model. Through iterative and structured discussions, variables related to process, service information and user’s expectations are identified, which are subsequently grouped into four dimensions. A survey method is used to get the primary data for this research from 3PL service users’ organizations in the Delhi and adjoining capital region. ACSI is used to prioritize the most preferred driver of satisfaction.FindingsEnablers related to process involving order processing, order picking, order fulfillment and final decision making stand out as the winners and also other critical areas have been identified.Practical implicationsThere is a gap between the services obtained and services expected and information-related complications which lead to unsatisfied customers. The 3PL service providers need to focus on these areas for better business performance and healthy and long-lasting business relationships.Originality/valueThe paper is an attempt to implement a satisfaction model for the 3PL sector from user’s perspective.
Workgroup diversity
Authors: Abu Bakar Hassan , McCann Robert M. 
Published: January 2018

Purpose
The purpose of this paper is to explore whether surface-level actual similarity interacts with leader-member dyadic communication agreement in predicting group member performance ratings at earlier time periods in a work group’s development. Additionally, this research examines whether deep-level perceived similarity interacts with leader-member dyadic communication agreement in predicting group member performance ratings at later time periods in a work group’s development. The relationship between shared cultural context and perceived and actual similarity is also investigated.

Design/methodology/approach
This research analyzes longitudinal data from the study questionnaires at five occasions in a Malaysian organization.

Findings
Results based on a sample of 28 group projects and 141 matching dyad who completed the study questionnaires at 5 occasions reveal that there is no interaction between workgroup relational ethnicity and workgroup relational gender with leader-member dyadic agreement at early time periods in a workgroup’s development. Therefore, H1 is not supported. H2 posited that deep-level perceived similarity will interact with leader-member dyadic communication agreement in predicting group member performance ratings at later time periods in a workgroup’s development. H2 is supported. Results reveal that the interaction between leader-member dyadic communication agreement and perceived similarity explains 36 percent of the variance of perceived group members’ performance ratings. This is after accounting for the control variable and the independent variables. From a cultural standpoint, the findings in this study underscore that conversations based on the Malaysian cultural norm of “budi” reflect not only a cultural basis of communication, but also that this shared cultural context leads to perceived similarity between ethnic Malay, Chinese, and Indians, and also both genders in the Malaysian workplace.

Research limitations/implications
Leader-member dyadic communication agreement reflects the social appropriateness and relationship quality between individuals, as well as the context of the leader-member workgroup interactions. The findings of this study underscore the premise that conversations reflect not only a cultural basis of communication, but also that shared cultural context leads to perceived similarity. This study specifically examines the role of ethnicity in Malaysia organizational workgroup (e.g. ethnic Malay, Chinese Malay, and Indian Malay) as well as gender.

Originality/value
This study systematically examines the influence of actual and perceived similarity in leader-member dyadic communication from a longitudinal and multilevel standpoint.
Calling for leadership: leadership relation with worker’s sense of calling
Authors: Esteves Tiago , Lopes Miguel Pereira , Geremias Rosa Lutete , Palma Patricia Jardim 
Published: January 2018

Purpose
The purpose of this paper is to understand the relation between leadership perception and workers’ sense of calling.

Design/methodology/approach
Workers’ sense of calling has been shown to relate to organizational outcomes such as job satisfaction, career development, personal growth, and well-being. Although recent studies point the sense of calling as a consequent of several organizational variables, the role of leadership in promoting workers’ sense of calling is yet to be analyzed. A self-report questionnaire was applied to a group of 325 Portuguese nurses to analyze this relation. Structural equation modeling was used to analyze the results.

Findings
Results indicate a positive relation between a leader perceived as transformational or transactional and workers’ sense of calling. Directive and empowering leadership perception were found not to be related to calling. Unexpectedly, a significant positive relation with aversive leadership perception was identified.

Research limitations/implications
A confounding relation between aversive leadership perception and sense of calling cannot be excluded. It is possible that an unknown third variable, such as resilience or positive affect, is serving as a mediating bridge between leadership perception and the sense of calling. Further studies are necessary in order to explore this alternative path.

Originality/value
The sense of calling is known as a relevant organizational construct. Knowing what kinds of leadership promote workers’ sense of calling adds value for the literature and can help managers to learn how to improve their followers’ sense of calling.
Analysis of risk and the strengthening of the safety technical barriers: application of Skikda (Algeria) oil refining complex
Authors: Ait Ouffroukh Louiza , Chaib Rachid , Ion Verzea , Khochmane Lakhdar 
Published: January 2018

Purpose
Algeria occupies an important place in all of the oil-producing countries. However, in recent years, industrial facilities have experienced a rapid increase in the number of major industrial accidents and calamities, where fires and explosions have caused impacts and severe effects on people, property and the environment. Therefore, this paper aims to analyze the risks involved and assess the performance of the technical barriers at the thermo-hydraulic level of facilities at the level of the refinery of Skikda.

Design/methodology/approach
The most effective methods in this field of activity are the systematic analyses of deviations or failures. As working tools, hazard and operability (HAZOP) method and fault tree analysis (FTA) were used to identify the various possible risks that could lead to undesirable phenomena, with the Topping unit. Using this type of analysis, it is possible to understand what the most risky process steps are and, where appropriate, to propose appropriate corrective and preventive measures. HAZOP is dedicated to the analysis of the risks of thermo-hydraulic systems and to control drift parameters such as pressure, temperature and flow. Unfortunately, with its limitations to the detection of leaks, the authors completed the study by FTA, working with a predetermined set of process parameters associated with system operation (compression, temperature, flow, etc.). Each of these parameters are combined with a series of possible potential deviations (too much, little, inverse, etc). For each analyzed equipment, the relevant parameters are selected and combined with the relevant deviations. For each parameter of the deviant process, the causes and consequences are determined.

Findings
The combination of these two methods has allowed to highlight the various possible risks that could lead to undesirable phenomena, to respond to industrial expectations or even to manage the operation process safely. Thus, it enabled the authors to detect the weaknesses of the process. This allowed the authors to reinforce the technical safety barriers of the functional links of the process and propose appropriate, corrective and preventive measures.

Originality/value
The work intends to reflect the real situation in which companies face risks. The originality of the work is represented by the combination of two methods: HAZOP and the FTA. This association allowed the authors to identify areas of weakness to set priorities for action by the company, through organizational, technical and human solutions, while engaging in a process of continuous improvement.
Dispersion analysis of magneto-electro elastic plate of arbitrary cross-sections immersed in fluid
Authors: Selvamani Rajendran 
Published: January 2018

Purpose
This study aims to construct a mathematical model to study the dispersion analysis of magneto-electro elastic plate of arbitrary cross sections immersed in fluid by using the Fourier expansion collocation method (FECM).

Design/methodology/approach
The analytical formulation of the problem is designed and developed using three-dimensional linear elasticity theories. As the inner and outer boundaries of the arbitrary cross-sectional plate are irregular, the frequency equations are obtained from the arbitrary cross-sectional boundary conditions by using FECM. The roots of the frequency equation are obtained using the secant method, which is applicable for complex solutions.

Findings
The computed physical quantities such as radial stress, hoop strain, non-dimensional frequency, magnetic potential and electric potential are plotted in the form of dispersion curves, and their characteristics are discussed. To study the convergence, the non-dimensional wave numbers of longitudinal modes of arbitrary (elliptic and cardioid) cross-sectional plates are obtained using FECM and finite element method and are presented in a tabular form. This result can be applied for optimum design of composite plates with arbitrary cross sections.

Originality/value
This paper contributes the analytical model for the role of arbitrary cross-sectional boundary conditions and impact of fluid loading on the dispersion analysis of magneto-electro elastic plate. From the graphical patterns of the structure, the effects of stress, strain, magnetic, electric potential and the surrounding fluid on the various considered wave characteristics are more significant and dominant in the cardioid cross sections. Also, the aspect ratio (a/b) and the geometry parameters of elliptic and cardioids cross sections are significant to the industry or other fields that require more flexibility in design of materials with arbitrary cross sections.

Published: January 2018

OBJECTIVESThe histone methylation and acetylation pathway genes regulate cell growth and survival. Aberrations in this pathway are implicated in a variety of cancers. This study aimed to identify germline genetic variants in histone methylation and acetylation pathway genes that may contribute to risk in eight types of cancers and to explore the relation between the whole pathway and their risks in these types of cancers.METHODSGermline genetic variants in 89 genes in the histone methylation and acetylation pathway were explored. Gene‐based and pathway‐based associations with eight types of cancers were analyzed using logistic regression models and the permutation‐based adaptive rank‐truncated product method, respectively.RESULTSGene‐level associations revealed that genetic variants in 45 genes were significantly associated with the risk of cancer. The total histone methylation and acetylation pathway was significantly associated with the risk of esophageal squamous cell carcinoma (P = 0.0492) and prostate (P = 0.0038), lung (P = 0.00015), and bladder cancer (P = 0.00135), but not with breast (P = 0.182), pancreatic (P = 0.336) and gastric cancer (P = 0.347) and renal cell carcinoma (P =0.828).CONCLUSIONSOur study suggested there is an association between germline genetic variation at the overall histone methylation and acetylation pathway level and some individual genes with cancer risk. Further studies are needed to validate these relations and to explore relative mechanisms.
Hemoglobin A1c and diagnosis of diabetes
Authors: Ding Lin , Xu Yu , Liu Shanshan , Bi Yufang , Xu Yiping 
Published: January 2018

AbstractThe prevalence of diabetes is increasing markedly worldwide, especially in China. Hemoglobin A1c is an indicator of mean blood glucose concentrations and plays an important role in the assessment of glucose control and cardiovascular risk. In 2010, the American Diabetes Association included HbA1c ≥6.5% into the revised criteria for the diagnosis of diabetes. However, the debate as to whether HbA1c should be used to diagnose diabetes is far from being settled and there are still unanswered questions regarding the cut‐off value of HbA1c for diabetes diagnosis in different populations and ethnicities. This review briefly introduces the history of HbA1c from discovery to diabetes diagnosis, key steps towards using HbA1c to diagnose diabetes, such as standardization of HbA1c measurements and controversies regarding HbA1c cut‐off points, and the performance of HbA1c compared with glucose measurements in the diagnosis of diabetes.

AbstractCounter‐conditioning can be a valid strategy to reduce reinstatement of reward‐seeking behavior. However, this has not been tested in laboratory animals with extended cocaine‐taking backgrounds nor is it well understood, which individual differences may contribute to its effects. Here, we set out to investigate the influence of serotonin transporter (5‐HTT) genotype on the effectiveness of counter‐conditioning after extended access to cocaine self‐administration. To this end, 5‐HTT+/+ and 5‐HTT−/− rats underwent a touch screen‐based approach to test if reward‐induced reinstatement of responding to a previously counter‐conditioned cue is reduced, compared with a non‐counter‐conditioned cue, in a within‐subject manner. We observed an overall extinction deficit of cocaine‐seeking behavior in 5‐HTT−/− rats and a resistance to punishment during the counter‐conditioning session. Furthermore, we observed a significant decrease in reinstatement to cocaine and sucrose associated cues after counter‐conditioning but only in 5‐HTT+/+ rats. In short, we conclude that the paradigm we used was able to produce effects of counter‐conditioning of sucrose seeking behavior in line with what is described in literature, and we demonstrate that it can be effective even after long‐term exposure to cocaine, in a genotype‐dependent manner.
The search for the meaning of life in soil: an opinion
Authors: Young I. M. , Bengough A. G. 
Published: January 2018

SummaryThe introduction of impressive technologies in the search for life's diversity and activity in soil has led to remarkable new techniques and knowledge concerning the soil microbial community. These have led to finding some important links to function. However, we attest that the general lack of causality found between the many metrics of microbial diversity and populations of soil microbes and function is due, at least in part, to the lack of understanding of the links between microbial populations and dynamics to their physical habitat and attendant moisture conditions. In this opinion paper we explore the importance of this interplay between organism and habitat. Further, as an example of this interplay, we introduce the potential importance of nematode movement and gene transfer in bacterial populations.Highlights
The importance of the physical habitat is highlighted in soil microbiology studies.
The interplay between the soil–root–habitat is emphasized.
Seeking a functional understanding of biodiversity rather than a ‘biology of numbers and differences’ approach is proposed.
The movement of nematodes with respect to horizontal gene transfer is discussed.

Authors: Li G. , Sun G.‐X. , Ren Y. , Luo X.‐S. , Zhu Y.‐G. 
Published: January 2018

SummaryRapid industrialization and urbanization during recent decades are having dramatic effects on urban soil properties and lead to large discharges of pollutants, which inevitably affect the health of the soil, ecosystems and human populations. This paper provides a systematic review of the relations between urban soil and human health. First, it summarizes the organic and inorganic pollutants in urban soil and their potential risks to human health. Second, the relations between urban greenbelt land, soil microbial diversity and human health are also explored. Third, we propose that future research should focus on the integration of assessments of health risks with exposure pathways and site characteristics. Bioavailability‐based risk assessment frameworks for pollutants in urban soil can elucidate the complicated relations between urban soil, pollutant exposure and human health in cities. Finally, management of urban soil and policy should be strengthened in the future to maintain its sustainable development and utilization. More effort should be directed to understanding the relations between soil microbial diversity, green space and human health in cities.Highlights
Evidence indicates the importance of urban soil in maintaining human health.
Pollutants, green space and microbial biodiversity have been systematically summarized.
Urban vegetation and antibiotic resistance genes in urban soil have implications in human health.
Bioavailability of pollutants and antibiotic resistance genes should be considered for human risk assessment.
High dielectric constant and high‐Q in microwave ceramics of SrTiO3 co‐doped with aluminum and niobium
Authors: Chen Siliang , Li Lingxia , Yu Shihui , Zheng Haoran , Sun Zheng 
Published: January 2018

AbstractAl/Nb co‐doped SrTiO3 microwave ceramics with the composition of SrTi1–x(Al0.5Nb0.5)xO3 (x = 0.03, 0.05, 0.1, and 0.15) have been synthesized via a standard solid‐state reaction method. The substitution of (Al0.5Nb0.5)4+ in B‐site inhibits the reduction in Ti4+ ions and the growth of grain size, then the transport of mobile charge carriers is limited, and thus the Q value is improved. For the SrTi0.9(Al0.5Nb0.5)0.1O3 ceramics, in addition to their high dielectric constant (εr ~185), they exhibit correspondingly a high Qf value (~ 9077 GHz) at 2.9 GHz, making the microwave ceramics suitable for myriad device miniaturization and high‐performance wireless communication.
Ionic transport in AgI‐HgS‐As2S3 glasses: Critical percolation and modifier‐controlled domains
Authors: Kassem Mohammad , Khaoulani Sohayb , Bychkov Eugene 
Published: January 2018

AbstractElectrical measurements, dc and ac, show that (AgI)x(HgS)0.5‐x/2(As2S3)0.5‐x/2 glasses, 0.0 ≤ x ≤ 0.6, exhibit drastic changes in ionic conductivity σi with silver iodide additions. The ionic transport increases by 13 orders of magnitude with increasing silver content from ~0.002 to ~23 at.%, and the activation energy decreases from 1.05 to 0.35 eV. Two distinctly different ion transport regimes above the percolation threshold concentration, xc ≈ 30 ppm, were distinguished. The critical percolation regime at low silver content (≤ 2‐5 at.% Ag) is characterized by a random distribution of silver‐related entities and obeys a power‐law composition dependence of σi. The ion transport parameters depend on the host network connectivity, represented by the average coordination number <n0>, via the critical fictive temperature T0; the calculated T0 value is comparable to the glass transition temperature for the glassy (HgS)0.5(As2S3)0.5 host matrix. In contrast, in the modifier‐controlled domain, the silver‐related entities are nonrandomly distributed. The high Ag+ ionic mobility results from interconnected tetrahedral (AgI2/2S2/2)n chains in the silver iodide content range 0.2 < x ≤ 0.5, and from 2D layers (Ag3/3I3/3)n or 3D mixed tetrahedral subnetwork (AgI3/3S1/2) in the range x > 0.5.

Published: January 2018

AbstractFerroelectric phase coexistence was constructed in (1−x)BaTiO3‐xCaSnO3 lead‐free ceramics, and its relationship with the piezoelectricity of the materials was investigated to ascertain potential factors for strong piezoelectric response. It is found that the addition of CaSnO3 caused a series of phase transitions in the (1−x)BaTiO3‐xCaSnO3 ceramics, and a ferroelectric coexistence of rhombohedral, orthorhombic, and tetragonal phases is formed at x = 0.08, where the ceramics exhibit the lowest energy barrier and consequently facilitate the polarization rotation and extension, resulting in the optimal piezoelectricity of d33 and kp values of 550 pC/N and 0.60, respectively. Our study provides an intuitive insight to understand the origin of high piezoelectricity in the ceramics with the coexistence of multiferroelectric phases.
