Contextualizing or decontextualizing? The peril of using Western social capital scales in China
Authors: L. Avery Sherry , Y. Sun Judy , M. Swafford Patricia , L. Prater Edmund 
Published: June 2014

Purpose– The purpose of this study is to promote Chinese indigenous research by examining a case in which adopting social capital (SC) scales developed in the Western context for Chinese samples can decontextualize inter-firmguanximanagement in the Chinese context.Design/methodology/approach– Adopting the existing Western scales to measure SC, we collected data from Chinese executives participating in executive master of business administration programs on buyer–supplier relationship. Using the same items and data source, we identifiedpost hocfactors representingguanxidimensions. Ordinary least squared regressions were used for bothguanxiand SC dimensions to test the hypotheses.Findings– Our analysis showed that Chinese natives responded to the Western SC items according to their understanding and mindsets rooted inguanxi. This was evidenced by the results from thepost hoc-derivedguanxidimensions with the same data, which show better regression results for the hypotheses tested, although the construct validity was comparable. Adopting Western SC measurement scales deconceptualized the intricate Chinese context and inter-firm interactions.Research limitations/implications– It is inappropriate to borrow Western-developed scales for Chinese HRM research due to intricate differences in contexts. Doing so may run the risk of ignoring the Chinese context regarding the mechanisms and processes of complex human interactions, although it may produce superficial results consistent with the Western literature. Developing indigenous measurement scales should be considered not only as a preference but also as a requirement for Chinese management research.Originality/value– We empirically compared the difference between Western-developed measurement scales and a Chinese indigenous construct, as well as their impact on relationship management in relation to indigenous Chinese management research.
Exporting wine in complex times: a study among small and medium wineries
Authors: Duarte Alonso Abel , Bressan Alessandro , O’Shea Michelle , Krajsic Vlad 
Published: June 2014

Purpose– For many wineries, internationalisation strategies, particularly in the form of exports may provide opportunities and financial gains. However, as more wine producers enter and compete in an increasingly convoluted wine market, accordingly the “playing field” in the wine industry becomes increasingly complex. To shed more light into wineries’ internationalisation efforts through exports in the currently uncertain business climate, this preliminary study investigates a group of predominantly micro, small, and medium wineries from both New and Old Worlds of wine. The paper aims to discuss these issues.Design/methodology/approach– An online questionnaire was designed to gather data from winery owners and managers that invited to participate voluntarily in the study; a total of 499 usable responses were obtained.Findings– Diversifying and entering new markets, especially due to domestic competition are respondents’ main reasons for embarking in exports, while unfavourable currency exchange, issues of trust, or entry barriers are key challenges many of them face. Further, despite the relatively limited wine production of most participating wineries, respondents perceive a necessity to be present internationally. Indeed, rather than fitting into a specific business model/cycle, the current complex business environment is triggering export strategies among entrepreneurs.Originality/value– The fiercely competitive wine market and continuously changing consumer trends significantly contribute to the complexities the wine industry faces. However, few academic studies have investigated some of the complexities that wineries located in different geographic, economic, political, and social environments face. In this regard, the study makes a contribution by identifying several developments related to complexity theory, including the impacts of globalisation, competition, and change, and the resulting complexity in the wine sector.
A modified Preisach model and its inversion for hysteresis compensation in piezoelectric actuators
Authors: Wang Xuan , Reysett Aurélien , Pommier-Budinger Valérie , Gourinat Yves 
Published: June 2014

Purpose– Piezoelectric actuators (PEAs) exhibit hysteresis nonlinearity in open-loop operation, which may lead to unwanted inaccuracy and limit system performance. Classical Preisach model is widely used for representing hysteresis but it requires a large number of first-order reversal curves to ensure the model accuracy. All the curves may not be obtained due to the limitations of experimental conditions, and the detachment between the major and minor loops is not taken into account. The purpose of this paper is to propose a modified Preisach model that requires relatively few measurements and that describes the detachment, and then to implement the inverse of the modified model for compensation in PEAs.Design/methodology/approach– The classical Preisach model is modified by adding a derivative term in parallel. The derivative gain is adjusted to an appropriate value so that the measured and predicted hysteresis loops are in good agreement. Subsequently, the new inverse model is similarly implemented by adding another derivative term in parallel with the inverse classical Preisach model, and is then inserted in open-loop operation to compensate the hysteresis. Tracking control experiments are conducted to validate the compensation.Findings– The hysteresis in PEAs can be accurately and conveniently described by using the modified Preisach model. The experimental results prove that the hysteresis effect can be nearly completely compensated.Originality/value– The proposed modified Preisach model is an effective and convenient mean to characterize accurately the hysteresis. The compensation method by inserting the inverse modified Preisach model in open-loop operation is feasible in practice.
FE modeling of creep in linear and non-linear FGM cylinder under internal pressure
Authors: Garg Manish , Deepak Dharmpal , Gupta V.K. 
Published: June 2014

Purpose
– The purpose of this paper is to investigate creep in an internally pressurized thick-walled, closed ends cylinder made of functionally graded composite, having linear and non-linear distribution of reinforcement, using finite element (FE) analysis.

Design/methodology/approach
– FE-based Abaqus software is used to investigate creep behavior of a functionally graded cylinder. The cylinder is made of composite containing linear and non-linearly varying distributions of reinforcement along the radius. The creep behavior has been described by Norton's power law. The creep stresses and strains have been estimated in linear and non-linear functionally graded materials (FGM) cylinders and compared with those estimated for a similar composite cylinder but having uniform distribution of reinforcement.

Findings
– The radial stress in the composite cylinder is observed to decreases over the entire radius upon imposing linear or non-linear reinforcement gradients. However, the tangential stress in the cylinder increases near the inner radius but decreases toward the outer radius, on imposing linear or non-linear reinforcement gradients. The creep strains in the FGM cylinders are significantly lower than those observed in a uniform composite cylinder.

Originality/value
– The creep strains in an internally pressurized functionally graded thick composite cylinder could be reduced significantly by employing non-linear distribution of reinforcement along the radial direction.
Organizational anonymity and the negotiation of research access
Authors: Taylor Scott , Land Christopher 
Published: June 2014

Purpose– The purpose of this paper is to examine the part of the organizational research process, access negotiation, through reflexive analysis of the participation in a recent data collection process. The paper aims is to question two emergent norms in this area: first, that organizational anonymity be granted in exchange for organizational access; and second, that access negotiation be seen as a bounded activity at the start of data collection.Design/methodology/approach– Through the reflexive account and with reference to published accounts of practice in other research projects, the authors explore the reasons why researchers offer organizational anonymity, and note the unintended consequences of this practice. The authors locate the discussion in relation to increased expectations on social researchers to contribute to public debate about managing and organizing.Findings– The author suggests that the negotiation of access without promising anonymity may generate more situated accounts of organization, and greater participation in political or ethical debates surrounding work, organization, and management. By facilitating a clearer line of impact stemming from qualitative research, this would also aid researchers in demonstrating the value of their work in informing public debate.Social implications– The authors conclude by reiterating the potential for organizational researchers to achieve greater social and ethical impact, especially if the authors frame access negotiation as a continuous process rather simply as than a moment at the start of a project.Originality/value– The authors argue that the paper raises a key, but neglected, issue in conducting empirical organizational research, that has political and ethical implications as well as a methodological significance. Through the analysis, the authors encourage themselves and the research community to be clearer about the potential value of scholarship in debates happening outside the academy, and to see access negotiation as more complex than simply a transaction in which organizational anonymity is promised in return for data.
Chronic morphine and tramadol re‐exposure induced an anti‐anxiety effect in prepubertal rats exposed neonatally to the same drugs

Published: June 2014

SummaryAnxiety disorders are among the most common mental disorders. Drugs that are often administered to manage medical problems cause rebound anxiety. The use of morphine and tramadol has increased in recent decades. In the present study, the effects of morphine and tramadol exposure during the neonatal and prepubertal periods on anxiety‐like behaviours in prepubertal rats were investigated. Male neonate rats were injected subcutaneously with saline, morphine or tramadol (3–21 mg/kg) on a daily basis from postnatal Day (P) 8 to P14. On P22, rats were divided into seven groups (saline/saline, saline/tramadol, saline/morphine, tramadol/saline, tramadol/tramadol, morphine/saline and morphine/morphine) and were injected with saline, tramadol or morphine for seven consecutive days. All rats were tested in an elevated plus maze (EPM) on P24 (acute effects), P27 (chronic effects) and P29. Locomotor activity was increased by the second and third exposure to the EPM. Re‐exposure to chronic morphine and tramadol resulted in increased locomotor activity, whereas acute and chronic administration of these drugs induced no notable difference. Anxiety decreased markedly after re‐exposure to tramadol and this anxiolytic‐like behaviour was more dominant in EPM re‐exposure in rats that had received higher doses of tramadol. Re‐exposure to tramadol elicited a stronger anxiolytic‐like behaviour than re‐exposure to morphine. It can be concluded that repeated morphine and tramadol administration during the neonatal period followed by re‐exposure to these drugs at an immature stage produces considerable anxiolytic‐like behaviour. Exposure to chronic morphine and tramadol during the neonatal period may affect the developing brain, which may induce long‐term changes in the opioid response.
The British National Security Strategy: Security after Representation
Authors: McCormack Tara 
Published: June 2014

Research Highlights and Abstract This article Contributes to the debate on British Foreign and Security Policy; Contributes to the literature on the British National Security Strategy; Links international relations literature with domestic policy formation literature; Introduces the concept of ‘legitimacy’ to foreign and security policy analysis. The publication of the Britain's first National Security Strategy (NSS) in 2008 marked a formal shift away from the secret state of the Cold War to the highly public protective state of today. This article is interested in the question of why the NSS and related framework have taken this particular public and explicit form. Both mainstream and critically minded academics have argued that contemporary security discourses and policies are techniques of power and governance and that the public nature of the policies is vital to this function. In this article, I argue that there has been a transformation in the nature of the British state from a representative state in which the state's authority was legitimated through a number of political mechanisms of representation, to one in which state elites and institutions need to forge new kinds of relationships with the governed. This is a key development that has been noticed in political, sociological and legal theoretical literature but as yet hardly addressed in international relations and security studies. This transformation of the state, I will argue, is intimately linked to the form and content of contemporary security policies. The contemporary state is undergoing a process of an erosion of legitimacy, which has a direct impact upon the capacity of the state to govern. In this context, policies take on the role of trying to bridge the legitimacy gap. I will argue that this shift in the state leads to a different understanding of contemporary security policies as representative of a decreasing ability to govern security, a state that is losing legitimacy and authority; that is in effect, losing its sovereignty. This article argues that British national security strategies and policies are representative of this.

Published: June 2014

AbstractIntroductionThe purpose of this study is to compare and evaluate volumetric modulated arc therapy (VMAT) and linear accelerator‐based radiosurgery (Linac RS) for the treatment of one to four brain metastases.MethodsRadiotherapy plans for 10 patients with 1 to 4 brain metastases that were planned and treated using conventional Linac RS were replanned using a mono‐isocentric VMAT technique using two to four arcs. The same doses, target volumes and organs at risk (OAR) were used in both plans. The plans were evaluated for target volume coverage, dose conformity, homogeneity and dose to OAR.ResultsFor VMAT plans, 18/19 brain metastases met acceptable Radiation Therapy Oncology Group (RTOG) radiosurgery dose coverage, homogeneity and conformity criteria. There was no observed difference between the mean homogeneity indices for VMAT and Linac RS plans. VMAT plans had a lower mean RTOG conformity index compared with the Linac RS plans (1.10 ± 0.06 versus 2.06 ± 1.02). For the OAR, there was no difference in maximal doses to the brain stem, optic chiasm or optic nerves. The volume of normal brain receiving 12 Gy was lower in the VMAT plans (13.3 cm3 versus 23.1 cm3) compared with the Linac RS plans. The mean total number of monitor units (MUs) was 31.3% less in the VMAT plans (5231.2 MU versus 3593.5 MU).ConclusionsMono‐isocentric VMAT plans using two to four arcs meet RTOG radiosurgery quality criteria in patients with one to four brain metastases, with an improvement in conformity and 12‐Gy normal brain volume when compared with patients treated with Linac RS at our institution.

Published: June 2014

AbstractRestriction site‐associated DNA sequencing (RADseq) provides researchers with the ability to record genetic polymorphism across thousands of loci for nonmodel organisms, potentially revolutionizing the field of molecular ecology. However, as with other genotyping methods, RADseq is prone to a number of sources of error that may have consequential effects for population genetic inferences, and these have received only limited attention in terms of the estimation and reporting of genotyping error rates. Here we use individual sample replicates, under the expectation of identical genotypes, to quantify genotyping error in the absence of a reference genome. We then use sample replicates to (i) optimize de novo assembly parameters within the program Stacks, by minimizing error and maximizing the retrieval of informative loci; and (ii) quantify error rates for loci, alleles and single‐nucleotide polymorphisms. As an empirical example, we use a double‐digest RAD data set of a nonmodel plant species, Berberis alpina, collected from high‐altitude mountains in Mexico.

AbstractAimsTo document the relationships between injecting drug use, imprisonment and hepatitis C virus (HCV) infection.DesignProspective cohort study.SettingMultiple prisons in New South Wales, Australia.ParticipantsHCV seronegative prisoners with a life‐time history of injecting drug use (IDU) were enrolled and followed prospectively (n = 210) by interview and HCV antibody and RNA testing 6–12‐monthly for up to 4 years when in prison.MeasurementsHCV incidence was calculated using the person‐years method. Cox regression was used to identify predictors of incident infection using time‐dependent covariates.ResultsAlmost half the cohort reported IDU during follow‐up (103 subjects; 49.1%) and 65 (31%) also reported sharing of the injecting apparatus. There were 38 HCV incident cases in 269.94 person‐years (py) of follow‐up with an estimated incidence of 14.08 per 100 py [confidence interval (CI) = 9.96–19.32]. Incident infection was associated independently with Indigenous background, injecting daily or more and injecting heroin. Three subjects were RNA‐positive and antibody‐negative at the incident time‐point, indicating early infection, which provided a second incidence estimate of 9.4%. Analysis of continuously incarcerated subjects (n = 114) followed over 126.73 py, identified 13 new HCV infections (10.26 per 100 py, CI = 5.46–17.54), one of which was an early infection case. Bleach‐cleansing of injecting equipment and opioid substitution treatment were not associated with a significant reduction in incidence.ConclusionsIn New South Wales, Australia, imprisonment is associated with high rates of hepatitis C virus transmission. More effective harm reduction interventions are needed to control HCV in prison settings.

AbstractBackgroundThe purpose of the current study was to investigate the long‐term clinical outcomes of this technique for degenerative scoliosis (DS).MethodsThe records of 95 consecutive patients with DS who underwent selective segmental transforaminal interbody fusion combined with posterior‐instrumented spinal fusion in our department from January 1999 to December 2007 were analysed retrospectively. Average follow‐up was 7.8 years. Recorded clinical outcomes included Oswestry Disability Index (ODI), visual analogue scale (VAS) pain scores and overall patient satisfaction. Radiographic measurements included coronal Cobb angle, apical vertebra translation, Nash–Moe grade, lumbar lordosis (LL) and thoracolumbar kyphosis. Comparison of the clinical and radiographic parameters before surgery and at final follow‐up was studied. Linear correlation analysis was applied to analyse the relationship between the clinical and radiological results.ResultsAverage ODI and VAS pain scores were significantly improved at final follow‐up compared with baseline (P = 0.038; P = 0.005). Specifically, the average ODI score was 32.2 ± 8.6 before surgery and 11.1 ± 6.8 at final follow‐up; the average VAS score was 8.9 ± 2.0 before surgery and 2.0 ± 1.2 at final follow‐up; patient satisfaction was 88.2% (84/95) at final follow‐up. In addition, Cobb angle, apical vertebra translation and Nash–Moe grade were all statistically significantly decreased compared with preoperative values (P = 0.019; P = 0.035; P = 0.001). Although LL had significantly increased (P = 0.022), thoracolumbar kyphosis did not exhibit a significant change (P = 0.64). There was significant correlation between LL and decreased ODI scores (r = 0.62, P = 0.01). Eleven patients (11.6%) underwent reoperation during the study period.ConclusionSelective segmental transforaminal interbody fusion combined with posterior‐instrumented spinal fusion appears to have reasonable long‐term clinical and radiographic outcomes for the treatment of DS.

SummaryBackgroundMagnetic resonance enterography (MRE) has been proposed as a non‐ionising alternative method to computed tomography enterography (CTE). Some studies have directly compared CTE and MRE in patients with small bowel Crohn's disease (CD) with variable results.AimTo compare the overall diagnostic accuracy in assessing the activity of small bowel and complications.MethodsMEDLINE, EMBASE and Cochrane databases were searched for studies on the accuracy of MRE and CTE, as compared with a pre‐defined reference standard. Pooled sensitivity, specificity, the weighted area under the curve (AUC), incremental yield (IY) and other diagnostic indices were evaluated.ResultsA total of 290 CD patients from six different studies were analysed. The pooled sensitivity and specificity for MRE in detecting active small bowel CD was 87.9% [95% confidence interval (CI), 81.8–92.5] and 81.2% (95% CI: 71.9–88.4) respectively. The AUC under the summary receiver‐operating characteristic (sROC) of MRE was 0.905 (SEM 0.03, standard error of the mean). Likewise, the pooled sensitivity and specificity of CTE in detecting active small bowel CD was 85.8% (95% CI: 79.2–90.9) and 83.6% (95% CI: 75.3–90.1) with the AUC of 0.898. The AUC of MRE in detecting fistula, stenosis and abscess was 0.936, 0.931 and 0.996, respectively, compared to 0.963, 0.616 and 0.899 of CTE. No statistically significant IY for MRE vs. CTE was found (fixed model, P > 0.05).ConclusionsMagnetic resonance enterography has a diagnostic effectiveness comparable to computed tomography enterography, thus may serve as a radiation‐free alternative for evaluation of patients with Crohn's disease.
