Am I treated better than my co-worker? A moderated mediation analysis of psychological contract fulfillment, organizational identification, and voice
Authors: Ali Arain Ghulam , Bukhari Sehrish , Hameed Imran , Lacaze Delphine M. , Bukhari Zahara 
Published: June 2018

PurposeThe purpose of this paper is to examine the direct and conditional indirect effects of employees’ perception of psychological contract fulfillment on their positive voice, i.e., promotive voice and prohibitive voice, through the integrated framework of the social exchange theory and the group value model.Design/methodology/approachUsing a two-source data collection from the employee and supervisor, cross-sectional data were collected from 234 participants working in one of the leading non-profit organizations in Pakistan. After initial data screening, a confirmatory factor analysis was conducted to test for the factorial validity of the employed measures with AMOS. The hypothesized relationships were tested in regression analysis with Statistical Package for the Social Sciences.FindingsThe results of this study supported the integration of the social exchange theory with the group value model in explaining the direct and indirect positive effects of employees’ perception of psychological contract fulfillment on their promotive and prohibitive voices through the mediation of organizational identification (OID). Furthermore, it was also recorded that the indirect effect was conditional on the employees’ perception of the relative psychological contract fulfillment which significantly moderated the direct relationship between psychological contract fulfillment and OID. However, no such effect was recorded for the moderating effect of power distance orientation between OID and the both voices.Originality/valueIn addressing the recently published research calls, this study broadens the horizon of existing research on psychological contract and employee positive voice by investigating the mediating and the moderating factors that influence this relationship.
Being sensitive to the culture: challenges in researching sensitive topics in an Asian culture
Authors: Adikaram Arosha S. 
Published: June 2018

Purpose
The purpose of this paper is to illustrate how the particular culture within which research is conducted and its norms and values can give rise to additional challenges and complications for the researcher when the research area is sensitive in nature.

Design/methodology/approach
Drawing on research on sexual harassment of working women in Sri Lanka, the researcher engages in self and methodological reflections to elucidate the many challenges faced.

Findings
Carrying out sensitive research in an Asian cultural context, with various stereotyping cultural norms, values and beliefs can give rise to additional culture-specific challenges for the researcher, even when the researcher is a cultural insider. How these cultural complexities influence the manner in which the participants respond to data collection and the manner in which the researcher is seen and understood by others are explained. Strategies to overcome these challenges are discussed in light of the cultural competencies propose by Deardorff and Sewyer et al.

Practical implications
The paper highlights the need for researchers engaged in sensitive research to carefully plan and conduct their research, being mindful not only to the sensitive nature of the topic, but also to the cultural edifices and ethos.

Originality/value
The influence of cultural context in conducting sensitive research is not sufficiently addressed. Culture-specific challenges that can arise in cultures outside the West, such as Asia, have specifically being neglected. This paper addresses this knowledge gap by focusing on the culture-specific challenges faced by researchers, whether they are cultural insiders or outsiders.
Pritchett Controls: ten years into employee ownership
Authors: Hoffman Richard C. , Decker Wayne H. , Shipper Frank 
Published: June 2018

Synopsis
This case illustrates the rationale for adopting employee ownership, and difficulties in implementing employee empowerment beyond investment. In the beginning it focuses on why Jerry Pritchett, one of the co-founders of Pritchett Controls, decided to convert it to an employee-owned company. In the body of the case, it details the efforts of the company to operate under its new ownership structure in an increasingly competitive environment. Although Pritchett established employee owners, only selected High Performance Work Systems (HPWS) practices have been implemented. The issue that reader must grapple with is whether other HPWS practices should be adopted or not.

Research methodology
Primary data were collected by interviewing eight managers including the current and former CEO at two of the firm’s three locations. Secondary data were used to supplement industry and competitive information.

Relevant courses and levels
Human resources courses, especially those that focus on strategic human resource management, organizational development, and how high performance organizations can be built, would be most appropriate for this case.

Theoretical bases
The primary theoretical foundations for this submission are shared entrepreneurship and HPWS. Knowledge of leadership, employee ownership, human resources, corporate governance, organizational culture and strategy would also be helpful in analyzing this case.
Analyzing children’s impact on parents’ tourist choices
Authors: Curtale Riccardo 
Published: June 2018

PurposeThe purpose of this study is to implement an innovative approach to analyze children’s impact on family decisions. Furthermore, a new strategy to collect children’s preferences is shown to reduce the lack of children’s voices in the tourism literature.Design/methodology/approachA stated preference (SP) experiment with a two-step procedure is applied: in the first step, children’s preferences are collected through pictures and a rating scale based on emoticons; in the second step, the SP is submitted to their parents to understand how children influence decisions. Parents faced six choice tasks, each of them showing three different activities that they could evaluate on the basis of three attributes: the cost of the activity, the distance from the place of interview and children’s degree of satisfaction in participating in the activity.FindingsThe majority of children interviewed show a high preference for swimming pool/lido, and their preference is highly taken into account by parents. Parents prefer closer and cheaper activities, but children’s preferences play a fundamental role in the final choice. In addition, parents are willing to pay an extra 100 CHF, for the whole family, to choose an activity that fulfills children’s preferences, rather than an activity that children do not like.Originality/valueThe originality contribution of this paper consists of using an innovative procedure to collect children’s preferences and combine them in an SP experiment submitted to their parents. Children’s influence on decisions is also measured by parent’s willingness to pay to satisfy their preferences.
7,8‐dihydroxyflavone enhanced cholinergic contraction of rat gastric smooth muscle via augmenting muscarinic M3 receptor expression
Authors: He Baoguo , Qu Zhiqiang , Tian Zibin , Zhao Kun , Wei Liangzhou , Ma Li 
Published: June 2018

SummaryAlthough 7,8‐dihydroxyflavone (7,8‐DHF), a synthetic agonist specific for tyrosine kinase receptor B (TrkB), has been reported to promote intestinal dynamics, its effect on gastric dynamics has not been studied as yet. In this study, we explored how 7,8‐DHF affected the carbachol (CCh)‐induced contraction of rat gastric muscle by way of measuring the contractile tension of muscular strips. We found that although 7,8‐DHF did not directly cause contraction of gastric muscle, it enhanced CCh‐induced, instead of substance P‐ or high K+‐induced, contraction. The enhancing role of 7,8‐DHF was partially blocked by ANA‐12, a blocker specific for TrkB the activation of which in the gastric strips was evidenced by its phosphorylation. Although 7,8‐DHF alone did not activate : phospholipase C (PLC)‐γ in gastric muscle, CCh did, and importantly, the combined treatment with CCh + 7,8‐DHF activated more PLC‐γ. U73122, an antagonist to PLC‐γ blocked both the CCh‐induced and the 7,8‐DHF‐enhanced/CCh‐induced contraction by ~30%. To pursue how 7,8‐DHF could augment CCh‐activated PLC‐γ phosphorylation, we first examined the effect of 7,8‐DHF on the expression of muscarinic receptors in gastric muscle and found that 7,8‐DHF specifically increased M3 but not M2 receptor expression possibly through TrkB/Akt (protein kinase B) pathway because the Akt antagonist, LY294002 significantly suppressed the 7,8‐DHF‐augmemted M3 expression and completely blocked the 7,8‐DHF‐enhanced cholinergic contraction. Supporting the result, Akt phosphorylation in the gastric muscle was enhanced by 7,8‐DHF treatment. The in vivo experiment showed that orally fed 7,8‐DHF increased gastric emptying rate. The results imply a possibility that 7,8‐DHF may be developed into a drug in the future for enhancing gastric dynamics.
When boards use related parties: outsourcing and superannuation fund performance
Authors: Liu Kevin , Ooi Elizabeth 
Published: June 2018

AbstractSuperannuation funds heavily outsource key fund functions to service providers who play a crucial role in superannuation fund operations and affecting Australians’ retirement savings. We examine the impact of related party service provider usage and trustee‐director affiliation on investment performance. We find that for‐profit funds significantly underperform when using related party service providers. The underperformance is more severe when the board is controlled by more affiliated trustee‐directors and belongs to a vertically integrated conglomerate group. Our results raise concerns about whether recent regulatory reforms increasing trustee‐directors’ duties effectively address the conflicts of interest inherent in related party service provider arrangements.

SummaryObjectiveCushing disease (CD) is a rare entity caused by ACTH‐secreting pituitary tumours, leading to prolonged hypercortisolism. Most cases are sporadic but can rarely occur in the context of familial predisposition, due to germline mutations in genes such as MEN1, leading to multiple endocrine neoplasia type 1, MEN1. We have reported previously that CD can be the first and only presenting manifestation of MEN1. In this report, we describe a cohort of paediatric patients who presented with CD as the first manifestation of MEN1.Materials and MethodsA retrospective analysis of paediatric patients admitted to the National Institutes of Health (NIH) Clinical Center for evaluation of hypercortisolism, between 1997 and 2017. MEN1 was diagnosed on a clinical, familial and/or genetic basis.ResultsOf a total of 238 children with CD, six patients were subsequently diagnosed with MEN1, three males and three females with a mean age at diagnosis of CD at 13.4 ± 2.9 years. Five of the six patients had familial MEN1 and one patient was a sporadic case. Additional manifestations of MEN1 included primary hyperparathyroidism in three patients and hyperprolactinemia in two patients.DiscussionThis report describes a paediatric patient population with MEN1 in whom CD was the initial manifestation, confirming a previous observation that paediatric patients with MEN1 may present first with an ACTH‐producing adenoma. Therefore, germline MEN1 mutations should be sought in paediatric CD and tested for when there is a suggestive family history and/or other manifestations.
Uncovering hidden coral diversity: a new cryptic lobophylliid scleractinian from the Indian Ocean

Published: June 2018

AbstractExtant biodiversity can easily be underestimated owing to the presence of cryptic taxa, even among commonly observed species. Scleractinian corals are challenging to identify because of their ecophenotypic variation and morphological plasticity. In addition, molecular analyses have revealed the occurrence of cryptic speciation. Here, we describe a new cryptic lobophylliid genus and species Paraechinophyllia variabilis gen. nov., sp. nov., which is morphologically similar to Echinophyllia aspera and E. orpheensis. The new taxon occurs in Mayotte Island, Madagascar, the Gulf of Aden and the Red Sea. Six molecular markers (COI, 12S, ATP6‐NAD4, NAD3‐NAD5, histone H3 and ITS) and 46 morphological characters at three different levels (macromorphology, micromorphology and microstructure) were examined. The resulting molecular phylogenetic reconstruction showed that Paraechinophyllia gen. nov. represents a distinct group within the Lobophylliidae that diverged from the lineage leading to Echinophyllia and Oxypora in the Early Miocene, approximately 21.5 Ma. The morphological phylogenetic reconstruction clustered Paraechinophyllia gen. nov., Echinophyllia and Oxypora together in a single clade. A sole morphological character, calice relief, discriminated Paraechinophyllia gen. nov. from the latter two genera, suggesting that limited morphological variation has occurred over a long period. These results highlight the importance of cryptic taxa in reef corals, with implications for population genetics, ecological studies and conservation.

Published: June 2018

AbstractAimThe second Association of Coloproctology of Great Britain and Ireland (ACPGBI) Ileoanal Pouch Registry (IPR) report was released in July 2017 following a first report in 2012. This article provides a summary of data derived from the most recent IPR report (2017 Ileoanal Pouch Report. https://www.acpgbi.org.uk/content/uploads/2016/07/Ileoanal-Pouch-Report-2017-FINAL.compressed.pdf).MethodThe IPR is an electronic database of voluntarily submitted data including patient demographics, disease, intra‐operative and postoperative factors submitted by consultant surgeons or delegates. Data up to 31 March 2017 have been analysed for this report.ResultsA total of 5352 pouch operations were carried out at 76 UK and four European centres by 154 surgeons over four decades. Recorded procedures have increased over time but data submission is voluntary and underestimates actual volume. Significant variation exists in institutional volume; 73 centres entered data on patients undergoing pouch surgery during the past 5 years. Of these, 44 centres have submitted ≤ 10 cases, with 10 centres submitting one patient and nine centres two cases. Since 2013, minimal access surgery has been employed in 54% of cases. Rectal dissection was undertaken in the total mesorectal excision plane in 69%. J‐pouch configuration was used in 99% of cases and 90% of pouch–anal anastomoses were performed using a stapled technique. Including all years, the IPR rate of pelvic sepsis was 9.4% and the rate of pouch failure was 4.7%.ConclusionThe IPR holds the largest voluntary repository of data on ileoanal pouch surgery. The second report from the IPR records marked refinements in surgical technique over time but also highlights wide variation in institutional caseload and outcome across the UK.
Treatment of acquired reactive perforating dermatosis – a systematic review
Authors: Lukács Judit , Schliemann Sibylle , Elsner Peter 
Published: June 2018

SummaryReactive perforating dermatosis is a rare chronic skin disease defined by the transepidermal elimination of collagen and/or elastin. In the acquired form in adults, it is frequently associated with diseases such as diabetes and chronic renal failure. No systematic reviews of treatment options are available for this disease. The aim of this systematic review is to summarize all reported treatment options for acquired reactive perforating dermatosis (ARPD). This is a systematic review based on a MEDLINE search of articles in English and German from 1990 to 2016.Most medical literature on the treatment of ARPD is limited to individual case reports and small series of patients. Various therapies that have been tried include antihistamines, topical keratolytics, corticosteroids, tretinoin, oral drugs such as allopurinol or antibiotics, and phototherapy or photochemotherapy.While there are no specific criteria for the evidence‐based selection of treatment options for ARPD, the first priority in management of these conditions should be treatment of an underlying disease if present. None of the described modalities has been approved for first‐line therapy. It is recommended to choose a combination of drugs that reduce itching and assist in the resolution of the skin lesions at the same time.

AbstractAimEnvironmental changes that amplify rates of site or patch occupancy turnover can increase risks of decline in spatially structured populations. We asked whether local habitat and meso‐scale climate influenced site occupancy turnover rates in four American pika (Ochotona princeps) metapopulations. We focused on winter cold stress, which is a proposed driver of American pika extinction risk but has been rarely studied.LocationOregon, Northern California, and Idaho.MethodsWe developed Bayesian hierarchical multiseason site occupancy models that accounted for both false‐negative and false‐positive survey detection errors to explore the winter stress turnover hypothesis. We used remotely sensed meso‐scale (1 km) snowpack and temperature data and fine‐grained local habitat attributes as covariates to model site persistence and colonization rates.ResultsThe estimated magnitude of imperfect detection was greater than previously reported for the species. After accounting for imperfect detection, we found no evidence of declines in site occupancy over the 5‐year study period, but our models provided evidence that pika site occupancy turnover can be high (>50% between some years) and apparently exacerbated by winter cold stress, summer heat stress and variation in site habitat quality. However, strength of evidence varied among metapopulations, suggesting influential local contingencies, as reported previously for the species.Main conclusionsOur empirical results suggest that the American pika may be vulnerable to wintertime turnover, negatively exacerbated by climatic events, with implications for future persistence given forecasted snowpack declines across the species’ range. Our models suggest a more nuanced dynamism to persistence and extinction risk than the simple scenario of inexorable, monotonic range contraction offered by static range‐wide distribution models, and we suggest several ways to strengthen these insights with future studies.
Nonvolatile chemicals provide a nest defence mechanism for stingless bees Tetragonula carbonaria (Apidae, Meliponini)

Published: June 2018

AbstractSocial insects construct nests that protect their brood and food resources from both the physical environment and natural enemies. Stingless bees use plant‐derived resins, mixed with wax to form propolis, in the construction of their nests, and these products can be effective sources of defense against natural enemies, including ants. However, it is not known whether this defense, in the form of deterring or repelling workers, derives from the physical properties or chemical compounds of these products. The nest entrance of Tetragonula carbonaria is constructed with propolis and Corymbia resins, and we ask whether nonvolatile chemicals present in these products act as a defense against ants. Our field experiments revealed that workers of Iridomyrmex mayri Forel were deterred from crossing a chemical barrier comprising nonvolatile, nonpolar (hexane) extracts of propolis and Corymbia tree resin. However, polar (ethanol) extracts did not have this effect. These data are the first to demonstrate that the chemical components alone of entrance propolis and resins can provide a nest‐defense function against ants.

Published: June 2018

SummaryBackgroundCastration is one of the most common surgical procedures performed in the horse. Complication rate and types of complications associated with use of the Henderson equine castrating instrument have not been determined.ObjectiveTo determine the complication rate and type of complications encountered when using the Henderson equine castrating instrument in equine ambulatory practice.Study designRetrospective case series.MethodsMedical records of horses undergoing routine castration using the Henderson drill were identified and evaluated for the occurrence of complications. The relationship between potential risk factors and complications was examined using basic descriptive statistics and quantified by means of logistic regression.ResultsOf 252 horses in the study population, 27 (10.7%) developed a complication after surgery; 25 of which were nonlife‐threatening and responded to medical management. Two complications, one each of wound botulism and evisceration, resulted in euthanasia. Age at the time of castration was significantly associated with the occurrence of (P = 0.005, Wilcoxon rank sum test) complications. Compared to younger horses, the odds of having a complication were significantly greater (OR 2.99, 95% CI 1.27–7.0; P = 0.01) for horses of 4 years of age or more.Main limitationsThe retrospective nature of this study. There is also a lack of direct comparison between different castration methods.ConclusionsThe Henderson equine castrating instrument is an acceptable alternative to traditional emasculators. Its use is associated with a low rate of complications (8.3%) in young horses (≤3 years of age) compared to older horses (21.3%) and a very low rate of serious complications (0.8%) in all ages of horses.
