Behavioral and attitudinal outcomes of psychological contract violation
Authors: Biswas Soumendu 
Published: February 2016

Purpose– The purpose of this paper is to explore the interactive effects of psychological contract violation (PCV) and leader member exchange (LMX) on workplace behaviors and attitudes. Another purpose of this research was to contribute to the existing literature pertaining to PCV and organizational cynicism in the context of managerial employees working in India.Design/methodology/approach– Data were collected from 237 managerial-level employees and 156 of their immediate supervisors of seven organizations in India. A questionnaire comprising 36 items pertaining to the study constructs was administered. The reliability of the instrument was verified through item analyses. A confirmatory factor analysis (CFA) was conducted to establish the instrument’s construct validity. Study hypotheses were tested and competing models were compared using structural equation modeling (SEM) procedures.Findings– All scales were found to have acceptable reliability estimates. A CFA established that the manifest variables loaded significantly on their latent constructs and that the latter were empirically distinct. This established the scales’ construct validity. The results of the SEM procedures indicated that all study hypotheses could be accepted as statistically significant. Also, the moderator variable had a quasi-interactive impact on the criterion variables.Originality/value– This research is among the first of its kind to examine the variables of PCV and organizational cynicism among managerial employees working in India. It may also be one of the few meso-level investigations in extant literature examining the interaction between an individual (PCV) and a group (LMX) level variable and its impact on workplace behavior (organizational citizenship behavior) and attitudes (organizational cynicism).
Corporate social responsibility – from a mere concept to an expected business practice
Authors: Amin-Chaudhry Anjum 
Published: February 2016

Purpose– In the past hundred years, the concept of corporate social responsibility (CSR) has seen a remarkable development with various notions of “what is the right thing to do” for the corporations in that era. This paper aims to highlight the journey of CSR staring from an “abstract concept” in the early twentieth century to a well-recognised and “expected business practice” in the present.Design/methodology/approach– This paper presents a meta-analysis of the relevant CSR literature and finds 12 common themes emerging in different periods. This is presented in a chronological order starting from early 1920 to the present day for ease of understanding. The literature chosen is intentionally broad as not to miss a clear view of the times and the themes in CSR discourse.Findings– The concept of CSR was viewed as a “social obligation” in the earlier literature (1920s-1960s), as the businesses were thought to operate for the well-being of a community and not for the prosperity of the sole owner(s). A little later, in the 1960s and 1970s, only adoption of socially responsible activities and practices, which were voluntary and beyond legal obligation, were deemed CSR. The 1980s saw businesses trying to find a rational and financially quantifiable justification for adopting activities that were socially responsible, thus the emphasis of “corporate social performance”. The 1990s shifted the impetus on “reporting, transparency and accountability” with numerous reporting requirements. The 2000s sought a win-win situation through the development of “creating shared value” as a result of adopting CSR initiatives. The concept of CSR became an “accepted and expected business practice” in the decade of 2000, with various governments, global entities and organisations issuing their own understanding and definitions of CSR.Originality/value– This research paper provides an account of the evolution in the concept of CSR in the past century which has seen numerous changes in the manner businesses conduct their operations. The identified themes are reflective of the journey of CSR. This is an informative paper which is very topical in today’s climate of stakeholder scrutiny of business’ working.

Published: February 2016

Purpose– The purpose of this research is to investigate the factors determining the social and environmental reporting (SER) of Indian textile and apparel (TA) firms.Design/methodology/approach– The 2010 annual reports of a sample of top 100 Indian TA firms listed on the Bombay Stock Exchange were examined to assess the extent of SER. SER was assessed based on the Global Reporting Initiative index applicable to the TA industry. Multiple regression analysis was conducted to investigate the determinants of SER.Findings– This study reports a low extent of SER in the annual reports of Indian listed TA firms, with a mean disclosure of 14 per cent. On average, firms reported more extensive environmental information, with a mean disclosure of 18.4 per cent, compared to social information, with a mean disclosure of 10.7 per cent. Most firms reported social information relating to “labour practices and decent work”, while the reporting of information relating to “human rights” was sparse. Overall, the SER patterns provide support for legitimacy theory. Consistent with legitimacy theory expectations, corporate size, brand development and audit committee size are significant factors determining the variation in SER. No significant relationship was found between board independence, level of ownership and SER.Originality/value– There is no existing study specifically on SER by TA firms in India. In fact, there is surprisingly little research on SER in the Indian context in general. Given the dearth in research on corporate social reporting in the Indian context, the study extends prior literature on corporate SER by concentrating on SER of TA firms in an emerging economy. The theoretical contribution of this study is the testing of legitimacy theory in the context of an emerging economy. This study contributes towards practice by delineating the relationship between governance structure and SER, particularly with regard to issues such as child labour. These findings have implications for the future development of reporting standards and regulations in regard to corporate governance in India. The dearth of social reporting by Indian TA firms has implications for foreign purchasers of branded products, as international companies have been implicated in sub-optimal social or environmental practices or incidents.
Corporate social responsibility diffusion by multinational subsidiaries in Indonesia: organisational dynamic and institutional effect
Authors: Famiola Melia , Adiwoso Siti Adiprigandari 
Published: February 2016

Purpose– The purpose of this study is to explore the extent of relational and institutional pressures’ influence on both the motivation for and diffusion of corporate social responsibility (CSR) practices of multinational corporation (MNC) subsidiaries in the food industries in Indonesia.Design/methodology/approach– This study uses qualitative approach, and the data were collected by interviewing CSR managers and investigating the CSR practices and the annual reports of six subsidiaries of food-manufacturing MNCs in Indonesia.Findings– This study found that internal pressures within MNC organisations are the main drivers of their CSR practices. These finding were, then, refined to account for local cognitive and normative institutional pressures. It was also found that while regulation in a host country was critical to its subsidiary compliance, it did not contribute appreciably to the precise types of CSR practices. The (isomorphic) similarity of CSR patterns had less to do with the institutional pressures but more with sector- or field-level pressures in food manufacturing. Most MNC subsidiaries focused on issues such as agricultural or rural development (related to their supply chain) or health and nutrition (related to their core business).Research limitations/implications– This study focuses on a specific industrial sector (food and beverage manufacture); therefore, the isomorphic patterns could not be concluded as an influential effect of the institutional context of Indonesia; rather, they are due to sectoral- or field-level pressure in food and beverage manufacturing. To confirm this study results, a multi-sectoral involvement in future studies is suggested.Originality/value– This study uses organisational dynamics and institutional theory to explore CSR adoption in multinational subsidiaries in Indonesia.
A limit on dose reduction possible with CT reconstruction algorithms without prior knowledge of the scan subject
Authors: Hsieh Scott S. , Chesler David A. , Fleischmann Dominik , Pelc Norbert J. 
Published: February 2016

Purpose:To find an upper bound on the maximum dose reduction possible for any reconstruction algorithm, analytic or iterative, that result from the inclusion of the data statistics. The authors do not analyze noise reduction possible from prior knowledge or assumptions about the object.Methods:The authors examined the task of estimating the density of a circular lesion in a cross section. Raw data were simulated by forward projection of existing images and numerical phantoms. To assess an upper bound on the achievable dose reduction by any algorithm, the authors assume that both the background and the shape of the lesion are completely known. Under these conditions, the best possible estimate of the density can be determined by solving a weighted least squares problem directly in the raw data domain. Any possible reconstruction algorithm that does not use prior knowledge or make assumptions about the object, including filtered backprojection (FBP) or iterative reconstruction methods with this constraint, must be no better than this least squares solution. The authors simulated 10 000 sets of noisy data and compared the variance in density from the least squares solution with those from FBP. Density was estimated from FBP images using either averaging within a ROI, or streak‐adaptive averaging with better noise performance.Results:The bound on the possible dose reduction depends on the degree to which the observer can read through the possibly streaky noise. For the described low contrast detection task with the signal shape and background known exactly, the average dose reduction possible compared to FBP with streak‐adaptive averaging was 42% and it was 64% if only the ROI average is used with FBP. The exact amount of dose reduction also depends on the background anatomy, with statistically inhomogeneous backgrounds showing greater benefits.Conclusions:The dose reductions from new, statistical reconstruction methods can be bounded. Larger dose reductions in the density estimation task studied here are only possible with the introduction of prior knowledge, which can introduce bias.

Object To explore the unfolded protein response (UPR) in the hippocampus of rats undergoing heroin relapse and the mechanisms underlying the acupuncture-mediated inhibition of brain damage caused by heroin relapse. Methods 60 Sprague-Dawley rats (30 females and 30 males) were randomly divided into four groups: Control group, Heroin group, Heroin+acupuncture group, and Heroin+methadone group (n=15 each). In the latter three groups, a model of heroin addiction was established by successive increments of intramuscular heroin injections for 8 days, according to the exposure (addiction)→detoxification method. A UPR RT2 Profiler PCR array was used to screen for differentially expressed genes in the hippocampus. Apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) staining. The protein expression levels of the following three differentially expressed genes were detected by Western blot to validate the results of the PCR array: heat shock protein (HSP)70, HSP105, and valosin-containing protein (Vcp). Results The UPR RT2 Profiler PCR Array detection results indicated that acupuncture increased the expression levels of the molecular chaperones HSP70, HSP105, and Vcp. The degree of neuronal apoptosis in the hippocampus of rats in the Heroin+acupuncture and Heroin+methadone groups was significantly reduced compared with the untreated Heroin group (p<0.01). Protein expression of HSP70, HSP105, and Vcp in the Heroin+acupuncture and Heroin+methadone groups was significantly higher than the Heroin group (p<0.01). Conclusions The positive effects of acupuncture on brain damage caused by heroin may be closely related to up-regulation of HSP70, HSP105, and Vcp, and reduced apoptosis.

Background and objectiveVery preterm children may be at risk of voice abnormalities (dysphonia). Risk factors previously identified in extremely preterm children include female gender, multiple intubations, complicated intubation and very low birth weight. This study sought to identify the prevalence of dysphonia in very preterm children, at school age.MethodsChildren born between 23 and 32 weeks’ gestation were included in this prospective observational study. Participants were randomly selected from a sample stratified by gestational age and number of intubations, and were aged between 5 and 12 years at the time of assessment. Clinical voice assessments were conducted by a speech pathologist, and a diagnosis of dysphonia was made based on the presence and severity of disturbance to the voice. Retrospective chart review identified medical and demographic characteristics.Results178 participants were assessed. The prevalence of dysphonia in this cohort was 61%. 31% presenting with significant dysphonia, that is, voice disturbance of greater than mild in severity. Female gender (p=0.009), gestational age (p=0.031) and duration of intubation (p=0.021) were significantly associated with dysphonia although some preterm children with dysphonia were never intubated.ConclusionsSignificant voice abnormalities were observed in children born at up to 32 weeks’ gestation, with intubation a major contributing factor.Trial registration numberACTRN12613001015730.
Any qualified provider: a qualitative case study of one community NHS Trust's response

Published: February 2016

ObjectiveTo examine how those managing and providing community-based musculoskeletal (MSK) services have experienced recent policy allowing patients to choose any provider that meets certain quality standards from the National Health Service (NHS), private or voluntary sector.DesignIntrinsic case study combining qualitative analysis of interviews and field notes.SettingAn NHS Community Trust (the main providers of community health services in the NHS) in England, 2013–2014.ParticipantsNHS Community Trust employees involved in delivering MSK services, including clinical staff and managerial staff in senior and mid-range positions.FindingsManagers (n=4) and clinicians (n=4) working within MSK services understood and experienced the Any Qualified Provider (AQP) policy as involving: (1) a perceived trade-off between quality and cost in its implementation; (2) deskilling of MSK clinicians and erosion of professional values; and (3) a shift away from interprofessional collaboration and dialogue. These ways of making sense of AQP policy were associated with dissatisfaction with market-based health reforms.ConclusionsAQP policy is poorly understood. Clinicians and managers perceive AQP as synonymous with competition and privatisation. From the perspective of clinicians providing MSK services, AQP, and related health policy reforms, tend, paradoxically, to drive down quality standards, supporting reconfiguration of services in which the complex, holistic nature of specialised MSK care may become marginalised by policy concerns about efficiency and cost. Our analysis indicates that the potential of AQP policy to increase quality of care is, at best, equivocal, and that any consideration of how AQP impacts on practice can only be understood by reference to a wider range of health policy reforms.

Published: February 2016

ObjectivesDuring surgery the volume of administered fluid is debated. Pro-atrial natriuretic peptide (proANP) is released by atrial distension, and we evaluated the relationship between changes in proANP associated with perioperative fluid balance.DesignProspective observational study.SettingOne university/tertiary centre.ParticipantsThe study included patients who underwent radical cystectomy. Plasma for determination of proANP was obtained before surgery, after resection of the bladder, and at the end of surgery for 20 robotic-assisted radical cystectomy (RARC) and 20 open radical cystectomy (ORC) procedures.ResultsThe blood loss was 1871 (95% CI 1267 to 2475) vs 589 mL (378 to 801) in the ORC and RARC groups (p=0.001), respectively, and fluid balance was positive by 1518 mL (1215 to 1821) during ORC, and by 1858 mL (1461 to 2255) during RARC (p=0.163). Yet, at the end of ORC, plasma proANP was reduced by 23% (14% to 32%, p=0.001), while plasma proANP did not change significantly during RARC. Thus, plasma proANP was associated both with the perioperative blood loss (r= −0.475 (0.632 to −0.101), p=0.002), and with fluid balance (r=0.561 (0.302 to 0.740), p=0.001), indicating that a stable plasma proANP required a fluid surplus by 2.4 L (2.0 to 2.7).ConclusionsThere was a correlation between intraoperative haemorrhage and a decrease in plasma proANP and, taking plasma proANP to indicate filling of the heart, about 2.5 L surplus volume of lactated Ringer's solution appears to maintain cardiac preload during cystectomy.Trial registration numberEudraCT (2012-005040-20), Results.

Published: February 2016

We perform a comprehensive study of the ability of the Deep Underground Neutrino Experiment (DUNE) to answer outstanding questions in the neutrino sector. We consider the sensitivities to the mass hierarchy, the octant of [Formula: see text] and to CP violation using data from beam and atmospheric neutrinos. We evaluate the dependencies on the precision with which [Formula: see text] will be measured by reactor experiments, on the detector size, beam power and exposure time, on detector magnetization, and on the systematic uncertainties achievable with and without a near detector. We find that a 35 kt far detector in DUNE with a near detector will resolve the eightfold degeneracy that is intrinsic to long baseline experiments and will meet the primary goals of oscillation physics that it is designed for.
Analysis of the peak position and linewidth as a function of temperature for the phase transitions in LiKSO4
Authors: Yurtseven H. , Kurt M. 
Published: February 2016

Analysis of the peak position and the linewidths of various infrared modes is performed at high (300–850 K) and low (1.5–300 K) temperatures using the experimental data from the literature for LiKSO4 which exhibits a sequence of phase transitions. The temperature dependences of the frequency and the linewidth which are derived from the anharmonic self-energy are fitted to the observed peak positions and the linewidths of the S–O stretching modes (internal [Formula: see text] modes at 1135 cm[Formula: see text] and at 1180 cm[Formula: see text]), peak position of the S–O bending [Formula: see text] (internal) modes, the peak position and the linewidth of the Li mode at 429 cm[Formula: see text] (external mode), and of the infrared band at 363 cm[Formula: see text] for LiKSO4. Our calculated peak positions and the linewidths, which are in good agreement with the observed data show that the anharmonic self-energy model describes adequately the observed behavior of the successive phase transitions in LiKSO4.
Restriction-Modification systems interplay causes avoidance of GATC site in prokaryotic genomes

Published: February 2016

Palindromes are frequently underrepresented in prokaryotic genomes. Palindromic 5[Formula: see text]-GATC-3[Formula: see text] site is a recognition site of different Restriction-Modification (R-M) systems, as well as solitary methyltransferase Dam. Classical GATC-specific R-M systems methylate GATC and cleave unmethylated GATC. On the contrary, methyl-directed Type II restriction endonucleases cleave methylated GATC. Methylation of GATC by Dam methyltransferase is involved in the regulation of different cellular processes. The diversity of functions of GATC-recognizing proteins makes GATC sequence a good model for studying the reasons of palindrome avoidance in prokaryotic genomes.In this work, the influence of R-M systems and solitary proteins on the GATC site avoidance is described by a mathematical model. GATC avoidance is strongly associated with the presence of alternate (methyl-directed or classical Type II R-M system) genes in different strains of the same species, as we have shown for Streptococcus pneumoniae, Neisseria meningitidis, Eubacterium rectale, and Moraxella catarrhalis. We hypothesize that GATC avoidance can result from a DNA exchange between strains with different methylation status of GATC site within the process of natural transformation. If this hypothesis is correct, the GATC avoidance is a sign of a DNA exchange between bacteria with different methylation status in a mixed population.
Risk-return trade-off, information diffusion, and U.S. stock market predictability
Authors: Xie Haibin , Wang Shouyang 
Published: February 2016

Recent academic literature in finance documents both risk-return trade-off and gradual information diffusion (ID). Motivated by these two financial theories, this paper proposes the ARCH-M model augmented by an ID indicator to forecast the U.S. stock market returns. Empirical studies performed on the monthly S&P500 index show that our approach is useful in both statistical and economic sense. Further analysis shows that the ID provides complementary information to risk-return trade-off effect. Our findings confirm that financial theories are valuable for stock return forecasting.
