Published: May 2018

Purpose
Organizational fairness has been shown to affect numerous employee outcomes, including organizational commitment and job satisfaction. The purpose of this paper is to explore whether an expatriate manager’s favorability toward accepting a foreign assignment affects the way they respond to subsequent treatment in the workplace, viewed in terms of organizational justice.

Design/methodology/approach
Data were gathered in two stages from 175 expatriate managers located in the United Arab Emirates (UAE). To test the authors’ predictions, the authors analyzed organizational commitment and job satisfaction as a function of organizational fairness (distributive and interpersonal) and pre-departure opinion.

Findings
The results suggest that expatriate managers who express a higher degree of favorability toward accepting a foreign assignment appear less reactive to changes in organizational fairness. Meanwhile, expatriate managers who express a lesser degree of favorability toward accepting the foreign assignment appear more sensitive to workplace fairness, such that when they feel treated unfairly, they demonstrate worse outcomes than those who were in favor of the assignment, and when they feel treated fairly, they demonstrate better outcomes than those who were in favor of the assignment. The net effect of pre-departure opinion appears to be an amplification of the relationship between subsequent fairness and outcomes.

Practical implications
Expatriate managers with a less favorable view of their assignment may harbor deep questions about whether they want to be in this new job capacity, and may therefore be more sensitive to how they are treated. Alternatively, people with a more favorable view of their assignment may have already decided they want to be in the new capacity, and so may be more robust to workplace treatment.

Originality/value
To the authors’ knowledge, this paper constitutes the first investigation of the effects of expatriate pre-departure opinion (i.e. favorability toward accepting a foreign assignment) on job satisfaction and commitment within the context of organizational justice. Furthermore, the UAE is a highly relevant context to study expatriate behavior.
Absorptive capacity and small family firm performance: exploring the mediation processes
Authors: Chaudhary Sanjay , Batra Safal 
Published: May 2018

PurposeDespite the recognized importance of knowledge management for small family firms, relatively little empirical research has been done so far to understand the mechanisms through which absorptive capacity (AC) assists their performance. The purpose of this study is to understand the relationship between absorptive capacity and performance in small family firms.Design/methodology/approachIn this study, the authors theoretically argue and empirically validate that AC enables the creation of entrepreneurial, market and technology orientations in small family firms, which, in turn, lead to superior firm performance. They also tested the study’s hypotheses using mediation and multiple linear regression analyses on data collected from 272 small Indian family firms.FindingsThe study’s findings suggest indirect relationship between AC and performance. The strategic orientations provide a mechanism through which investments in small family firms’ AC results in firm performance.Practical implicationsThis study offers crucial insights to practitioners and small firm managers regarding the use of knowledge-based capabilities in creating appropriate strategic postures, which, in turn, assist firm performance.Originality/valueThis study is among few research attempts in understanding the knowledge aspects of small family firms. The present research contributes to the existing literature by unravelling the relationship between knowledge management and small family firm performance. Also, by bringing in data from an under-studied context of an emerging economy, this study strengthens the theoretical applicability of knowledge management in different contexts.
The “hero-leader”: a case of leadership in Brazil
Authors: Casado Renata 
Published: May 2018

PurposeThe purpose of this paper is to explore what mechanisms a leader uses when promoting change towards a corporate social responsibility (CSR) framework in the particular context of the Brazilian culture.Design/methodology/approachThis is a qualitative case study undertaken at a private forest management company located in the South of Brazil, which draws on in-depth interviews with employees (n=12) and analysis of secondary data. Content analysis supported by Atlas TI software.FindingsFirst, this study illustrates the importance of transformational leadership as an internal organisational antecedent for successful organisational change towards CSR practices and policies. This is particularly because this transformation was grounded in moral values, which were used by the leader to build trust, inspire and motivate followers. Second, this case study provides a glimpse into the implementation of CSR practices in a Brazilian organisational setting, suggesting that characteristics that are typical of the national culture reinforce the importance of the leader as a role model, inside and outside the firm, in various realms of the employees’ lives.Research limitations/implicationsThe study makes a contribution in extending the understanding about the relationship between leadership and CSR in the context of Brazilian culture. However, as a qualitative case study, findings from this research should not be generalised. Results must be understood in light of the specific conditions in which the case is embedded.Practical implicationsThe paper identifies key messages for international companies interested in promoting change in their Brazilian businesses or operations. It also stimulates reflection on the issue of dependency on the leader and eventual challenges regarding continuity and succession.Originality/valueThe paper offers an in-depth analysis of leadership challenges and mechanisms in an organisation embedded in the Brazilian culture.
Separating the wheat from the chaff with the winnowing fork
Authors: Ngoepe Mpho , Nkwe Marcia 
Published: May 2018

Purpose
Appraisal of records to separate the wheat (records of enduring value) from the chaff (ephemeral records) is one of the most important functions of the archives. In terms of the National Archives and Records Service of South Africa (NARSSA) Act (No. 43 of 1996) (the Act), “no public records may be transferred to an archives repository, destroyed, erased or otherwise disposed of without the written authorisation of the national archivist”. In implementing this section of the Act, the NARSSA issues a disposal authority, which emanates from the appraisal process explained in the policy guidelines of 2002. The purpose of the study is to analyse the appraisal policy guidelines on the approach of NARSSA in relation to preservation of digital records.

Design/methodology/approach
This study has used qualitative data obtained through content analysis and literature to review the appraisal policy guidelines and approach of NARSSA in relation to preservation of digital records. The 2002 approved appraisal policy, as well as the directives issued by NARSSA in terms of Section 13(4) of the Act, is examined to determine the criteria, the process and the methodology adopted in the appraisal of records. Content analysis data are augmented through interviews conducted in person with the head of the records management unit at NARSSA and the archivist responsible for appraisal of government records.

Findings
The study has established that, in terms of the approach, records are appraised two years after the implementation of records classification systems in governmental bodies and those of archival value are then transferred to an archives repository after a period of 20 years. Twenty years is a long period as records might be lost, especially in digital environments. Furthermore, the appraisal policy guidelines limit the powers of records managers in governmental bodies in deciding on records of enduring value, as this responsibility is assigned to archivists at NARSSA. It is clear that the policy was written with paper records in mind.

Research limitations/implications
This study may go a long way in influencing policy review to embrace appraisal of digital records in South Africa. This in turn will help in determining the feasibility of preservation technology for digital records.

Originality/value
This study is useful to ensure participation of the public in the appraisal process. This study has triangulated content analysis data with interviews to examine appraisal criteria, process and methodology, followed by NARSSA.

Published: May 2018

AbstractDoenjang (Korean fermented soybean paste) with an improved flavor and safety was prepared by the simultaneous fermentation of autochthonous mixed starters at the pilot plan scale. First, whole soybean meju was fermented by coculturing safety‐verified starters Aspergillus oryzae MJS14 and Bacillus amyloliquefaciens zip6 or Bacillus subtilis D119C. These fermented whole soybean meju were aged in a brine solution after the additional inoculation of Tetragenococcus halophilus 7BDE22 and Zygosaccharomyces rouxii SMY045 to yield doenjang. Four doenjang batches prepared using a combination of mold, bacilli, lactic acid bacteria, and yeast starters were free of safety issues and had the general properties of traditional doenjang, a rich flavor and taste. All doenjang batches received a high consumer acceptability score, especially the ABsT and ABsTZ batches. This study suggests that flavor‐rich doenjang similar to traditional doenjang can be manufactured safely and reproducibly in industry by mimicking the simultaneous fermentation of autochthonous mixed starters as in traditional doenjang fermentation.Practical ApplicationThe development of a pilot plant process for doenjang fermentation using safety‐verified autochthonous mixed starter will facilitate the manufacture of flavor‐rich doenjang similar to traditional doenjang safely and reproducibly in industry.

SummaryThe reduction of CO2 emissions is a global effort which is not only supported by the society and politicians but also by the industry. Chemical producers worldwide follow the strategic goal to reduce CO2 emissions by replacing existing fossil‐based production routes with sustainable alternatives. The smart use of CO and CO2/H2 mixtures even allows to produce important chemical building blocks consuming the said gases as substrates in carboxydotrophic fermentations with acetogenic bacteria. However, existing industrial infrastructure and market demands impose constraints on microbes, bioprocesses and products that require careful consideration to ensure technical and economic success. The mini review provides scientific and industrial facets finally to enable the successful implementation of gas fermentation technologies in the industrial scale.
Immunological blocking of spermidine‐mediated host–pathogen communication provides effective control against Pseudomonas aeruginosa infection
Authors: Wang Jianhe , Wang Jing , Zhang Lian‐Hui 
Published: May 2018

SummaryPseudomonas aeruginosa is known to cause life‐threatening infections. The previous studies showed that the type III secretion system (T3SS) of this pathogen is a key virulence determinant, which is activated by polyamines signals spermidine (Spd) and spermine (Spm) from mammalian host. To test the potential of blocking host–pathogen communication in disease control, in this study we developed a high potency mouse monoclonal antibody (Mab 4E4, IgG1 sub‐isotype) by using Spm–protein conjugate as an immunogen. Antibody specificity analysis showed that the antibody specifically recognize Spd and Spm. In vitro study showed the antibody significantly protected A549 cells against P. aeruginosa infection, and this protection was achieved by blocking polyamine uptake and downregulating T3SS expression. In vivo single injection of mouse with Mab 4E4 drastically reduced the serum polyamine level, which was maintained for more than 1 week. In a murine model of P. aeruginosa acute infection, injection of Mab 4E4 protected mice from lung injury and significantly improved the survival rate of mice.

Published: May 2018

AbstractPurposeDifferent implant‐abutment connections are available and it has been claimed they could have an effect on marginal bone loss. The aim of this review is to establish if implant connection configuration influences peri‐implant bone loss (PBL) after functional loading.MethodsA specific question was formulated according to the Population, Intervention, Control, and Outcome (PICO): Does the type of implant‐abutment connection (external, internal, or conical) have an influence on peri‐implant bone loss? A PubMed/MEDLINE electronic search was conducted to identify English language publications published in international journals during the last decade (from 2006 to 2016). The search was conducted by using the Medical Subject Headings (MeSH) keywords “dental implants OR dental abutment AND external connection OR internal connection OR conical connection OR Morse Taper.” Selected studies were randomized clinical trials and prospective studies; in vitro studies, case reports and retrospective studies were excluded. Titles and abstracts and, in the second phase, full texts, were evaluated autonomously and in duplicate by two reviewers.ResultsA total of 1649 articles were found, but only 14 studies met the pre‐established inclusion criteria and were considered suitable for meta‐analytic analysis. The network meta‐analysis (NMA) suggested a significant difference between the external and the conical connections; this was less evident for the internal and conical ones. Platform‐switching (PS) seemed to positively affect bone levels, non‐regarding the implant‐connection it was applied to.ConclusionsWithin the limitations of this systematic review, it can be concluded that crestal bone levels are better maintained in the short‐medium term when internal kinds of interface are adopted. In particular, conical connections seem to be more advantageous, showing lower peri‐implant bone loss, but further studies are necessary to investigate the efficacy of implant‐abutment connection on stability of crestal bone levels.

Published: May 2018

AbstractBackgroundCurrently, there is incomplete understanding of the fracture patterns in the implant and their association with clinical factors.PurposeThe aim of this study was to investigate the incidence and pattern of implant fracture (IF) by using 9‐year, long‐term multicenter follow‐up data.Materials and MethodsThe association of the incidence and differences in fracture patterns with clinical factors (based on patient variables and implant variables) was assessed for statistical significance using the Chi‐square and Fisher exact test, as appropriate.ResultsAmong a total of 19 087 implants in 8501 patients (7838 male and 663 female) placed over 9 years, fractures were observed in 70 implants (0.4%) in 57 patients (50 male and 7 female). Cases with less than 50% bone loss had a higher incidence of horizontal and vertical IFs limited to the crest module, which are defined as Type I fractures (n = 13, 18.6%). In contrast, cases with ≥50% severe bone loss exhibited a higher incidence of Type II vertical fractures (n = 22, 31.4%), extending beyond the crestal portion (P = .001). Type III fractures (n = 5, 7.1%), defined as a horizontal fracture beyond the crestal module, were also observed.ConclusionPeri‐implantitis‐induced marginal and vertical bone loss and manufacturing‐induced defects were considered to be major factors in IF. Therefore, using clinically verified implant systems and striving to minimize bone loss by preventing and actively treating peri‐implantitis is essential to reduce IFs.

Published: May 2018

AbstractIn view of the complex relationships involved in network structures, as well as the Markovian nature of information diffusion and the complexity of diffusion paths in social hotspots, we introduce and optimize a basic structure in social networks—the triad. A group behavior diffusion model is proposed based on the optimal triadic structure and factor graph. In addition to predicting individual participation behavior, the model forecasts group development trends of hotspots. First, considering the dynamics of social topic information diffusion, an information triad structure is proposed based on the traditional structure for analyzing the complex influencing factors. Second, in accordance with the Markovian nature of information diffusion, a group behavior diffusion model is proposed associated with the basic concepts and methods of random field theory. This model can not only capture the strengths of different influencing factors but also mine the dynamic patterns of topics. The experimental results reveal the efficiency of our model in both predicting individual participation behavior and perceiving group evolution trends in social hotspots.
A dynamic adaptive deviation registration algorithm for heterogeneous sensors

Published: May 2018

AbstractDeviation registration algorithm of homogeneous sensors has grown mature, but heterogeneous sensors deviation registration algorithm still faces the problems like strong nonlinearity and low precision, which needs urgent solutions. To eliminate the difficulties in deviation registration of heterogeneous sensors, especially the different dimensional sensors, the heterogeneous sensors deviation registration model and dynamic adaptive particle swarm optimized particle filter are proposed. In this paper, dynamic adaptive particle swarm optimized particle filter and Kalman filter is federated to carry out the real‐time calibration for the system deviation of radar and infrared sensor. With particle neighborhood information taken into account, this algorithm conducts a self‐adaptive adjustment over the number of particle's neighborhood particles by means of diversity factor, neighborhood extension factor, and neighborhood restriction factor. The adjustment is intended to control the influence of particle on neighborhood and reduce its local optimum so as to attain the optimal balance between convergence rate and optimization ability. The experimental result shows that the improved heterogeneous sensors deviation registration algorithm has upgraded the accuracy and speed of deviation registration; therefore, this algorithm is of high application value in the deviation registration of three‐dimensional radar and two‐dimensional infrared sensor.

Published: May 2018

SummaryRenal denervation (RDN) is a potential modality in the treatment of patients with resistant hypertension (RH) and has shown beneficial effect on a variety of cardiovascular surrogate markers. Coronary flow reserve, as assessed by transthoracic Doppler echocardiography (TDE‐CFR) is impaired in patients with hypertension and is an independent predictor of cardiac morbidity. However, data on the effect of RDN on TDE‐CFR are scarce. The main objective of this study was to assess the effect of RDN on TDE‐CFR. Twenty‐six consecutive patients with RH (9 female and 17 male; mean age 62 ± 8 years; mean number of antihypertensive drugs 4·2 ± 1·6) underwent bilateral RDN. CFR was assessed at baseline and 6 months after intervention. Mean flow velocity was measured in the left anterior descending artery by transthoracic Doppler echocardiography at baseline and during adenosine infusion (TDE‐CFR). Systolic office blood pressure was reduced at follow‐up (174 ± 24 versus 162 ± 27 mmHG; P = 0·01). Mean systolic ambulatory blood pressure decreased from 151 ± 21 to 147 ± 18 (P = 0·17). TDE‐CFR remained unchanged 6 months after intervention (2·7 ± 0·6 versus 2·7 ± 0·7; P = 0·67). In conclusion, renal denervation was not associated with any changes in regard to coronary flow reserve at 6‐month follow‐up.

Published: May 2018

AbstractEarly auditory/language experience plays an important role in language development. In this study, we examined the effects of severe‐to‐profound hearing loss and subsequent cochlear implantation on the development of attention to speech in children with cochlear implants (CIs). In addition, we investigated the extent to which attention to speech may predict spoken language development in children with CIs. We tested children with CIs and compared them to chronologically age‐matched peers with normal hearing (NH) on their attention to speech at four time points post implantation; specifically, less than 1 month, 3 to 6 months, 12 months, and 18 months post implantation. We also collected a variety of well‐established speech perception and spoken language measures from the children with CIs in a 10‐year longitudinal study. Children with CIs showed reduced attention to speech as compared to their peers with NH at less than 1 month post implantation, but a similar degree of attention to speech as their NH peers during later time points. In addition, attention to speech at 3 to 6 months post implantation predicts speech perception in children with CIs. These results inform language acquisition theories and bring insights into our understanding of early severe‐to‐profound hearing loss on infants’ attention to speech skills. In addition, the findings have significant clinical implications for early intervention on hearing loss, which emphasizes the importance of developing strong listening skills.
