Age diversity and team outcomes: a quantitative review
Authors: Schneid Matthias , Isidor Rodrigo , Steinmetz Holger , Kabst Rüdiger 
Published: February 2016

Purpose– The purpose of this paper is to synthesize the literature on the relationship between age diversity (AD) and the essential team outcomes (i.e. performance quality, financial performance, innovation and creativity, effectiveness, satisfaction, and turnover).Design/methodology/approach– The authors conduct a meta-analysis of the relationship between AD and team outcomes using a sample of 74 studies. Furthermore, the authors investigate the role of contextual factors (task complexity, type of performance evaluation, study setting, team size, age cohort) as moderators of the AD-team outcome relationship.Findings– The results show no significant overall relationships between AD and team outcomes, except for turnover (r=0.11,p< 0.05). Moderator analyses reveal significant albeit weak differences regarding task complexity, team size, and age cohort.Originality/value– The authors extend previous research by quantitatively reviewing the AD-team outcome relationship. By showing that AD is only related to turnover, the authors provide counter-evidence to many scholars arguing for the importance of AD for team outcomes. Additionally, the authors found some potential sources of the conflicting findings observed in the literature by considering contextual factors.
The customer-centric logic of multi-product corporations
Authors: Manral Lalit 
Published: February 2016

Purpose– The purpose of this paper is to articulate a customer-centric logic to explain the strategic behavior of multi-product corporations whose portfolio of complementary product offerings belong to diverse industries.Design/methodology/approach– The paper develops a theoretical framework to explain the heterogeneity in multi-product corporations ' motivation and ability to leverage the demand-side strategic assets developed in their home-markets to enter new markets and thereby improve their long-run corporate performance.Practical implications– The paper includes implications for strategic behavior of multi-product corporations in various industrial sectors such as telecommunications, financial services, consumer discretionary and staples, real estate, and so on.Originality/value– The profitable applicability of demand-side strategic assets to new contexts should be explained both by the motivation of multi-product consumers (to purchase a portfolio of complementary products from a diversified seller) as well as the motivation of multi-product corporations (to leverage their demand-side strategic assets to enter new markets).
Does accounting for uncertain tax benefits provide information about the relation between book-tax differences and earnings persistence?
Authors: Zhou Mingjun 
Published: February 2016

Purpose
– This study aims to use research setting provided by the implementation of Financial Accounting Standards Board Interpretation 48 (FIN48) to help develop a further understanding of large positive book–tax differences (LPBTD) and their relationship with earnings persistence. Extant literature indicates that the tax information provided in financial statements, such as large book–tax differences, is useful for detecting earnings management and signals less persistent future earnings. However, more information is needed about the causes of large book–tax differences and their abilities to signal the differences in earnings persistence (Blaylock et al., 2012).

Design/methodology/approach
– In the first step, temporary book–tax differences are ranked by quintiles based on the approach in Hanlon’s (2005) study and the highest quintile in the sample observations are designated as large positive temporary book–tax differences (LPBTD). In the second step, differences in the persistence of earnings for high tax-planning firms as measured by UTB_NonETR are searched for. In further testing, an ordered logistic model and the Vuong (1989) test are applied to compare both the incremental and the relative ability of UTB_NonETR and Cash-ETR to explain the ranking order of temporary book–tax differences.

Findings
– The negative relation between temporary differences and earnings persistence is moderated by the level of tax planning as measured by UTB_NonETRs. More specifically, the persistence of earnings appears to be higher for firm-years with large UTB_NonETRs. When comparing the relative power of UTB_NonETR with Cash-ETR, the results indicate that UTB_NonETR is incrementally useful for explaining the ranking orders of temporary book–tax differences. However, it appears that neither UTB_NonETR nor Cash-ETR is relatively more useful over another under the Vuong (1989) test.

Originality/value
– First, the part of UTB, if recognized, that would not affect earnings (UTB_NonETR) is used as an empirical proxy and its usefulness is tested in the context of book–tax differences and the persistence of earnings. Second, new evidence is provided supporting the predictions, as in Ayers’ et al. (2010) and Blaylock et al.’s (2012) studies, that the level of tax planning will attenuate the negative association between large book–tax differences and earnings quality. Third, the findings can contribute to the post-implementation review of FIN48 (Financial Accounting Foundation, 2012) supporting the argument that FIN48 can provide decision-useful information for financial statement users.
From bush to butchery: cattle rustling as an entrepreneurial process in Kenya
Authors: Bunei Emmanuel K. , McElwee Gerard , Smith Robert 
Published: February 2016

Purpose– The purpose of this paper is to provide an analysis of the changing practices of cattle rustling in Kenya from a relatively small isolated and opportunistic activity to a much more planned and systematic entrepreneurial business involving collusion and corruption.Design/methodology/approach– This paper provides a conceptual approach using key literature and documentary evidence to show how, in the northern part of Kenya, cattle rustling is common occurrence with criminals taking advantage of remote rural environments with minimal surveillance and consequently less opportunity of being stopped and searched by police.Findings– Results evidence significant differences in how rustling is perceived and valorized. Rustling in Kenya is now an entrepreneurial crime with the involvement of rural organized criminal gangs (ROCGs), who are operating in food supply chains throughout Kenya and the African continent.Practical/implications– This paper suggests that a more nuanced understanding of the entrepreneurial nature of some illegal practices in a rural Kenya is necessary and how it requires multi-agency investigation.Originality/value– The paper is unique in that it considers how cattle rustling is becoming a more entrepreneurial crime than previously. Little prior work on this subject exists in Kenya. The paper utilizes the framework of Smith and McElwee (2013) on illegal enterprise to frame cattle rustling as an entrepreneurial crime.
Financial Flexibility and At‐the‐Market (ATM) Equity Offerings: Evidence from Real Estate Investment Trusts
Authors: Hartzell David , Howton Shawn D. , Howton Shelly , Scheick Benjamin 
Published: February 2016

AbstractThis article examines at‐the‐market (ATM) equity programs as an additional source of financial flexibility. We find that firms with higher market‐to‐book ratios and greater institutional ownership are more likely to announce an ATM program. Firms using ATM programs are also more likely to issue shares when they have exhausted other viable financing alternatives, have timely investment opportunities and when market conditions are favorable. Finally, we document a significant negative announcement effect around the establishment of an ATM program, though the magnitude of this effect is significantly less negative than that of a comparable SEO.

Published: February 2016

AbstractPurposeTo describe the use of a novel intra‐ocular side‐scanning probe enabling the acquisition of spectral‐domain optical coherence tomography (SD‐OCT) images during surgery in a series of patients with complex forms of retinal detachment.MethodsA 23‐gauge, side‐scanning SD‐OCT probe (C7 System; LightLab Imaging, Inc/St Jude Medical, St. Paul, MN, USA) in a 20‐gauge catheter, was used to acquire the intra‐operative OCT images in seven patients with vitreoretinal diseases. Twenty‐five gauge pars plana vitrectomy (PPV) was performed in every patient in a standard fashion. After enlarging the temporal sclerotomy to a 20‐gauge port, all the patients were scanned with intra‐ocular side‐scanning SD‐OCT, during different steps of the surgery based on surgeon needs. Scans were recorded real time and directly evaluated on a screen during surgery. Optical coherence tomography (OCT) scans were judged beneficial when they would recognize structures otherwise not seen on biomicroscopy.ResultsThe intra‐ocular SD‐OCT has been helpful in acquiring extra information during vitreoretinal surgery such as the detection of the presence of otherwise invisible membranes (epiretinal membrane, subretinal membrane), the location of small tears and the identification of the retinal plane under suboptimal conditions for visualization.ConclusionThe use of an intra‐ocular SD‐OCT can expand upon visual cues during surgery, helping in the decision‐making process and allowing additional deliberate surgical manoeuvres aimed at improving surgical outcomes.

Published: February 2016

AbstractPurposeTo investigate and compare the 24‐hr intra‐ocular pressure (IOP) pattern among different severities of glaucomatous optic neuropathy (GON) together with different subtypes of primary open‐angle glaucoma (POAG).MethodsThe IOPs of untreated patients with POAG were measured every 2 hrs over a 24‐hr period. Subjects were divided into mild, moderate and severe groups according to the glaucoma staging system 2. The two POAG subtypes, normal tension glaucoma (NTG) and hypertension glaucoma (HTG) were classified according to peak IOP values throughout the 24‐hr period. The 24‐hr IOP curves were obtained based on the average IOP value at each time‐point. The mean, peak, trough and fluctuation of IOP together with the diurnal‐to‐nocturnal IOP change were calculated and compared among different groups.ResultsA total of 160 POAG patients (84 NTG and 76 HTG) were enrolled in the study. Generally, IOP decreased in the diurnal period and increased progressively during the nocturnal period, with peak IOP occurring from 2:00 AM to 10:00 AM. The average IOP values at all time‐points were significantly higher in the mild group compared to the moderate and severe groups (p < 0.05). Compared with the NTG subjects, the IOP parameters including mean, peak, trough and fluctuation were significantly higher in the HTG subjects (p < 0.001), and IOP increased more predominantly in the HTG subtype during the nocturnal period.ConclusionsThere was some regularity in the 24‐hr IOP pattern in POAG, but different severities of GON and different subtypes might present different characteristics. Other non‐IOP factors may lead to pathological IOP fluctuation and could be correlated with GON.

SummaryBackgroundIn patients with chronic hepatitis B (CHB)‐related hepatocellular carcinoma (HCC), high viral load was associated with tumour recurrence and deaths.AimsTo investigate the effect of nucleos(t)ide analogues (NA) on the clinical outcomes after different HCC treatments.MethodsA territory‐wide cohort study was conducted using the database from Hospital Authority. We identified CHB patients with HCC by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD‐9‐CM) diagnosis codes in 2000–2012. HCC treatments, NA use and laboratory parameters were retrieved. The primary endpoint was HCC recurrence and death. A 3‐month landmark analysis was used to evaluate the primary outcome in patients with or without NA treatment.ResultsA total of 2198 CHB patients (1230 NA‐untreated and 968 NA‐treated) with HCC, receiving at least one type of HCC treatment were included in the analysis. At a median follow‐up of 2.8 (IQR 1.4–4.9) years, tumour recurrence and death occurred in 451 (36.7%) and 578 (47.0%) untreated patients; and in 216 (22.3%) and 301 (31.1%) NA‐treated patients respectively. NA therapy reduced the risk of overall HCC recurrence [adjusted sub‐hazard ratio (SHR) 0.63, 95% confidence interval (CI) 0.49–0.80; P < 0.001]. The effect was most obvious in patients undergoing resection (SHR = 0.58, 95% CI = 0.37–0.91, P = 0.018). The possibility of NA therapy reducing the risk of death (HR = 0.82, 95% CI = 0.64–1.03, P = 0.092), is most obvious in resection subgroup (HR = 0.64, 95% CI = 0.41–0.99, P = 0.050) but insignificant in the other treatment groups.ConclusionOur findings show that nucleos(t)ide analogues treatment reduces the risk of HCC recurrence in patients with chronic hepatitis B treated by surgical resection.
Hyperglycemia Increases the Production of Amyloid Beta‐Peptide Leading to Decreased Endothelial Tight Junction

Published: February 2016

SummaryAimsAmyloid beta‐peptide (Aβ), the main component of senile plaques in the Alzheimer's disease (AD) brains, is generated from sequential cleavage of amyloid precursor protein (APP) by β‐ and γ‐secretase. Hyperglycemia in diabetes may compromise barrier integrity in endothelial cells (ECs). However, the roles of endothelial APP in response to high glucose (HG) remain to be delineated. The aims of this study were to test whether HG may increase Aβ secretion, thereby leading to heightened paracellular permeability in ECs.MethodsWe determined the effects of HG on production of Aβ, expression of full‐length APP, intercellular permeability, and expression levels of specific junctional proteins in human umbilical vein endothelial cells (HUVECs).ResultsHG at 30 mM significantly stimulated expression of full‐length APP accompanied by heightened secretion of Aβ1‐42, increased paracellular permeability, and attenuated expression of zona occluden‐1 (ZO‐1), claudin‐5, occludin, and junctional adhesion molecule (JAM)‐C in HUVECs; all of which were abolished by the γ‐secretase inhibitor BMS299897. Exogenous application of Aβ1‐42, but not the reverse peptide Aβ42‐1, was sufficient to downregulate the expression of the same junction proteins.ConclusionHyperglycemia enhances APP expression with increased Aβ production, which downregulates junctional proteins causing increased intercellular permeability in ECs.
Dietary restraint: what's the harm? A review of the relationship between dietary restraint, weight trajectory and the development of eating pathology

Published: February 2016

SummaryDietary restraint has historically been implicated as a risk factor for the development of eating pathology. Despite existing findings, recent research suggests that many individuals are capable of practicing dietary restraint without negative effects. In order to successfully incorporate the positive aspects of dietary restraint into interventions for healthy weight management, a nuanced examination of the relationship between dietary restraint and resulting eating patterns is necessary. Accordingly, the current review seeks to clarify the existing literature with regard to dietary restraint. First, this review examines the construct of dietary restraint and differentiates dietary restraint from related constructs, such as weight loss dieting. Second, it identifies situations in which dietary restraint has been linked with positive outcomes, such as healthy weight management and prevention of eating pathology. Altogether, it appears that dietary restraint can prove a beneficial strategy for those attempting to control their weight, as it does not relate to increased levels of eating pathology when practiced as part of a well‐validated weight management programme.

Published: February 2016

SummaryThe objective of the study is to investigate the effect of baseline anxiety and depression, using different definitions for caseness, on attrition and weight outcomes following a multidisciplinary weight management programme. The study design is a prospective observational study. The Hospital Anxiety and Depression Scale (HADS) was used to measure anxiety and depression with ‘caseness’ scoring ≥11 and severity ≥14. The participants were all patients who began a weight management programme between 1 October 2008 and 30 September 2009 (n = 1838). The setting was the Glasgow and Clyde Weight Management Service (GCWMS), a specialist multidisciplinary service, which aims to achieve a minimum of ≥5 kg weight loss. The results were as follows: patients with HADS score ≥14 were referred to the integrated psychology service for psychological assessment or intervention. Patients with caseness (HADS ≥11) for anxiety (33%) and depression (27%) were significantly younger, heavier, more socio‐economically deprived and a higher proportion was female. There was a significant positive correlation between HADS anxiety and depression scores and increasing body mass index (r2 = 0.094, P < 0.001 and r2 = 0.175, P < 0.001, respectively). Attendance and completion was lower throughout follow‐up amongst patients with anxiety or depression. More patients with HADS score ≥11 achieved ≥5 kg or ≥5% weight loss and by 12 months those with anxiety had a significantly higher mean weight loss (P = 0.032). Participants who scored for severe anxiety (HADS ≥14) achieved similar weight loss to those without, whilst participants who scored for severe depression achieved significantly greater weight loss than non‐cases at 3, 6 and 12 months of follow‐up (P < 0.01). Despite a less favourable case‐mix of risk‐factors for poor weight loss, patients who scored caseness for severe anxiety or depression and were offered additional psychological input achieved similar or better weight loss outcomes.

AbstractPlatelet‐released growth factors (PRGF) and its related clinically used formulations [e.g. Vivostat platelet‐rich fibrin (PRF®)] are thrombocyte concentrate lysates that support healing of chronic, hard‐to‐heal and infected wounds. Human beta‐defensin‐2 (hBD‐2) is an antimicrobial peptide expressed in human keratinocytes exhibiting potent antimicrobial activity against wound‐related bacteria. In this study, we analysed the influence of PRGF on hBD‐2 expression in human primary keratinocytes and the influence of Vivostat PRF® on hBD‐2 expression in experimentally generated skin wounds in vivo. Treatment of primary keratinocytes with PRGF caused a significant increase in hBD‐2 gene and protein expressions in a concentration‐ and time‐dependent manner. The use of blocking antibodies revealed that the PRGF‐mediated hBD‐2 induction was partially mediated by the epidermal growth factor receptor and the interleukin‐6 receptor (IL‐6R). Luciferase gene reporter assays indicated that the hBD‐2 induction through PRGF required activation of the transcription factor activator protein 1 (AP‐1), but not of NF‐kappaB. In concordance with these cell culture data, Vivostat PRF® induced hBD‐2 expression when applied to experimentally generated skin wounds. Together, our results indicate that the induction of hBD‐2 by thrombocyte concentrate lysates can contribute to the observed beneficial effects in the treatment of chronic and infected wounds.

AbstractIn the aftermath of the end‐Permian mass extinction, Early Triassic sediments record some of the largest Phanerozoic carbon isotopic excursions. Among them, a global Smithian‐negative carbonate carbon isotope excursion has been identified, followed by an abrupt increase across the Smithian–Spathian boundary (SSB; ~250.8 Myr ago). This chemostratigraphic evolution is associated with palaeontological evidence that indicate a major collapse of terrestrial and marine ecosystems during the Late Smithian. It is commonly assumed that Smithian and Spathian isotopic variations are intimately linked to major perturbations in the exogenic carbon reservoir. We present paired carbon isotopes measurements from the Thaynes Group (Utah, USA) to evaluate the extent to which the Early Triassic isotopic perturbations reflect changes in the exogenic carbon cycle. The δ13Ccarb variations obtained here reproduce the known Smithian δ13Ccarb‐negative excursion. However, the δ13C signal of the bulk organic matter is invariant across the SSB and variations in the δ34S signal of sedimentary sulphides are interpreted here to reflect the intensity of sediment remobilization. We argue that Middle to Late Smithian δ13Ccarb signal in the shallow marine environments of the Thaynes Group does not reflect secular evolution of the exogenic carbon cycle but rather physicochemical conditions at the sediment–water interface leading to authigenic carbonate formation during early diagenetic processes.
