Does investment in project management pay off?
Authors: Spalek Seweryn 
Published: June 2014

Purpose
– There is a significant knowledge gap in the common understanding regarding the value that investment leading to an increase in project management maturity brings to the organisation. The purpose of this paper is to narrow this gap by investigating the relationship between an increase in the project management maturity level and the project's performance. Additionally, it advocates the investment roadmap approach.

Design/methodology/approach
– This study is part of a worldwide research initiative into maturity in project management covering 447 global companies. For this purpose, survey data from experts from 194 select companies was analysed.

Findings
– The cost of forthcoming projects depends on the level of maturity of project management and type of industry.

Research limitations/implications
– The study is limited to three different industries (machinery, construction and information technology) and by the method of assessing their future project costs. New research directions are suggested.

Practical implications
– The results of the study should help companies in allocating limited resources appropriately using the proposed roadmap.

Social implications
– An increase in project management maturity can be achieved through different investment methods. This will benefit society as well.

Originality/value
– The paper focuses on global companies dealing in machinery. The area has not been explored sufficiently from the project management perspective. It discusses the relationship between an increase in maturity and future project costs in three industries: machinery, construction and information technology. The paper suggests practical guidelines for project management and sequences in proper investments when resources are limited.
Study of consumers’ behavior for non-vegetarian products in emerging market of India
Authors: Kumar Niraj , Kapoor Sanjeev 
Published: June 2014

Purpose
– The purpose of this paper is to understand non-vegetarian food consumption behavior, and factors affecting the same of the consumers of middle-sized market, where organized retailing is still at infancy.

Design/methodology/approach
– A total of 182 households of two middle-sized cities of India were personally surveyed with a structured questionnaire. Simple statistical analysis such as frequency distribution, factor analysis and analysis of variance, logit regression were carried out to infer the required information.

Findings
– Although an important constituent of the food, for most the consumers, purchase of non-vegetarian products were weekly, well planned, and family affairs. Assured good quality, followed by the meat preparation in front of the customers’ eye emerged important market attributes for selecting the store by the consumers. The study revealed that consumers were mainly dependent on search and credence attributes of the product for non-vegetarian food purchase decisions.

Research limitations/implications
– This paper analyses non-vegetarian food consumption food behavior of those customers, for whom non-vegetarian food is still considered as special food, and who belong to middle-sized cities where organized food retailing has just started.

Originality/value
– The subject is relatively less researched in emerging markets where organized food retail is still at infancy, and where non-vegetarian foods are considered special.
Getting inside the black box
Authors: Mansour Nizar , Gara Emna , Gaha Chiha 
Published: June 2014

Purpose– The purpose of this paper is to explore, and eventually unlocking, the “black box” problem by addressing the potential mediating role of human capital and organizational commitment in the relationship between high performance work systems (HPWS) and perceived firm performance in the Tunisian financial industry.Design/methodology/approach– Based on the strategic human resource management (SHRM) theory, the authors developed a model that links HPWS to perceived organizational performance through human capital and employee organizational commitment. Data collected from 351 respondents was considered. Multiple regression analysis was then used to assess the research hypotheses.Findings– Data collected from 351 respondents suggest that HPWS positively affect perceived firm performance through first, enhancing the firms’ human capital; and second, developing positive organizational commitment attitude among employees. In addition, a direct relationship between HPWS and firm performance was found.Research limitations/implications– The research focussed on the perceived performance of the organization rather than financial measures. Also, because data were collected from a sample of Tunisian financial companies, results of this study are not generalizable.Originality/value– More than two decades after the earliest contributions, the SHRM scholars believe that the “black box” problem is still accurate and, therefore, needs to be addressed in an effective way. At a general and broad level, the authors believe this study contributes to the SHRM literature by successfully addressing two critical “black box” elements, i.e. human capital and organizational commitment. Also, since there is a lack in such research in Tunisia, an icon country of the Arab spring, this paper provides theoretical basis for future research and managerial implications for Tunisian business leaders and HR managers. Finally, this research is extending the current empirical SHRM literature by addressing the critical role of HRM in the largely understudied field of financial services industry.
The impact of leader-member exchange (LMX) on work-family interference and work-family facilitation
Authors: G. Tummers Lars , A.C. Bronkhorst Babette 
Published: June 2014

Purpose– The purpose of this paper is to analyze the effects of leadership on work-family spillovers. Specifically, we analyze the relationships between leadership (leader-member exchange (LMX) with one negative work-family spillover effect (work-family interference) and one positive work-family spillover effect (work-family facilitation). The authors hypothesize that LMX influences work-family spillover via different mediators, rather than one all-encompassing mediator, such as empowerment.Design/methodology/approach– The authors hypothesize that a good relationship with your supervisor (high LMX) diminishes work pressure, which in turn reduces work-family interference. Furthermore, the authors expect that a good relationship with your supervisor positively relates to the meaningfulness of work, as you could get more interesting work and more understanding of your role within the organization. In turn, this will increase work-family facilitation. These hypotheses are tested using a nation-wide survey among Dutch healthcare professionals.Findings– Findings of structural equation modeling (SEM) indeed indicate that high-quality LMX is negatively related to work-family interference, and that this is mediated by work pressure (53 percent explained variance). Furthermore, the authors found that a good relationship with your supervisor is positively related to meaningfulness of work, which in turn positively correlates to work-family facilitation (16 percent explained variance).Originality/value– The added value of the paper lies in introducing two mediators – work pressure and meaningful work – which worked adequately both theoretically and empirically, instead of the sometimes problematic mediators empowerment and stress; a focus on healthcare professionals; and using sophisticated techniques to test the model (SEM with bootstrapping).
Effects of early employment experiences on anticipated psychological contracts
Authors: Eilam-Shamir Galit , Yaakobi Erez 
Published: June 2014

Purpose– The purpose of this paper is to investigate how initial employment experiences of new entrants to the labor market, which results from changes in organizations employment practices affect individuals’ expectations from their future employers (their anticipatory psychological contracts and anticipated job insecurity) and to explore the implications of these effects for theory and practice.Design/methodology/approach– The paper focussed on four common experiences and tested the hypotheses about their effects using data collected by a relatively large survey among mature college students with work experience (n=1,164).Findings– Individuals who had been exposed to the experiences of being laid off, witnessing layoffs and having to accept reductions in pay or status held higher transactional and lower relational expectations from their future employers, in comparison with individuals who had not been exposed to such experiences. They also anticipated a higher level of job insecurity in their future employment.Practical implications– In order to mitigate the potential negative consequences of the phenomenon discovered on employee retention and organizational performance, organizations have to develop and implement specific HR practices to deal with cohorts of new members, who have been exposed to the employment experiences investigated. Of particular importance are orientation and socialization practices that address new recruits’ concerns and expectations, and exposing new members to training and learning experiences that increase their employability outside the organization.Originality/value– This is one of a few studies that documents empirically the (anecdotally based) claims about the effects of changes in the economic environment on individuals’ employment expectations and perhaps the first study to focus specifically on the effects of initial experiences of entrants to the labor market. It extends psychological contract research by focussing on the antecedants and formation of the psychological contract rather than on its consequences and on the anticipatory contract rather than on employees’ current psychological contracts.
Qualitative research – mixed emotions
Authors: Humphrey Christopher 
Published: June 2014

Purpose– The purpose of this paper is to provide a personal, reflective analysis of publications over the last decade inQualitative Research in Accounting & Management(QRAM) and to assess the implications for the future development of the journal, the practice of qualitative accounting research and the broader standing of the accounting discipline.Design/methodology/approach– ReviewingQRAMpublished papers across a range of themes, including the spirit of generated debate, the representation and classification of qualitative research and the range of contributory authors. Using the review to identify important patterns and trends in the standing and practice of qualitative accounting research.Findings– Highlighting the existence and contribution of numerous carefully crafted, thought provoking papers published inQRAMand drawing on them to present a number of important challenges, priorities and attractive opportunities for the future development of qualitative accounting research. Encouraging greater diversity, flexibility and creativity in the undertaking and utilisation of qualitative accounting research.Practical implications– Emphasising how thinking differently about the emotions and lived experiences of qualitative accounting research(ers) can serve to inspire theoretical development, enhance trust in researcher judgement, and stimulate more fruitful and intellectually rewarding ways of doing qualitative accounting research.Originality/value– Reminding of the value of reading papers as compared to relying on formal journal rankings. Revealing residing defensiveness tendencies in the undertaking of qualitative accounting research and arguing that restrictive representations and conceptions of “legitimate” qualitative accounting research are constraining what can be achieved and experienced both by individual accounting researchers and the discipline more generally.
Three‐dimensional modelling of controlled‐source electromagnetic surveys using an edge finite‐element method with a direct solver
Authors: Chung Yonghyun , Son Jeong‐Sul , Lee Tae Jong , Kim Hee Joon , Shin Changsoo 
Published: June 2014

ABSTRACTA fully three‐dimensional finite‐element algorithm has been developed for simulating controlled‐source electromagnetic surveys. To exploit the advantages of geometric flexibility, frequency‐domain Maxwell's equations of the secondary electric field were discretised using edge‐based finite elements while the primary field was calculated analytically for a horizontally layered‐earth model. The resulting system of equations for the secondary field was solved using a parallel version of direct solvers. The accuracy of the algorithm was successfully verified by comparisons with integral‐equations and iterative solutions, and the applicability to models containing large conductivity contrasts was verified against published data. The advantages of geometry‐conforming meshes have been demonstrated by comparing different mesh systems to simulate an inclined sheet model. A comparison of the performance between direct and iterative solvers demonstrated the superior efficiency of direct solvers, particularly for multisource problems.
Bacteria associated with truffle‐fruiting bodies contribute to truffle aroma

Published: June 2014

SummaryTruffles, symbiotic fungi renown for the captivating aroma of their fruiting bodies, are colonized by a complex bacterial community of unknown function. We characterized the bacterial community of the white truffle Tuber borchii and tested the involvement of its microbiome in the production of sulphur‐containing volatiles. We found that sulphur‐containing volatiles such as thiophene derivatives, characteristic of T. borchii fruiting bodies, resulted from the biotransformation of non‐volatile precursor(s) into volatile compounds by bacteria. The bacterial community of T. borchii was dominated by α‐ and β‐Proteobacteria. Interestingly, all bacteria phyla/classes tested in this study were able to produce thiophene volatiles from T. borchii fruiting body extract, irrespective of their isolation source (truffle or other sources). This indicates that the ability to produce thiophene volatiles might be widespread among bacteria and possibly linked to primary metabolism. Treatment of fruiting bodies with antibacterial agents fully suppressed the production of thiophene volatiles while fungicides had no inhibitory effect. This suggests that during the sexual stage of truffles, thiophene volatiles are exclusively synthesized by bacteria and not by the truffle. At this stage, the origin of thiophenes precursor in T. borchii remains elusive and the involvement of yeasts or other bacteria cannot be excluded.

Published: June 2014

BackgroundInformation about the recurrence of spontaneous preterm birth in subsequent twin/singleton pregnancies is scattered.ObjectivesTo quantify the risk of recurrence of spontaneous preterm birth in different subtypes of subsequent pregnancies.Search strategyAn electronic literature search in OVID MEDLINE and EMBASE, complemented by PubMed, to find recent studies.Selection criteriaStudies comparing the risk of spontaneous preterm birth after a previous preterm and previous term pregnancy.Data collection and analysisThe absolute risk of recurrence with a 95% confidence interval and the absolute risk of preterm birth after a term delivery were calculated. Data from studies were pooled using the Mantel–Haenszel method.Main resultsWe detected 13 relevant studies. The risk of recurrence of preterm birth was significantly increased in all preterm pregnancy subtypes, compared with their term counterparts. Women pregnant with twins after a previous preterm singleton had the highest absolute risk of recurrence (57.0%, 95% CI 51.9–61.9%), and after a previous term singleton their absolute risk was 25% (95% CI 24.3–26.5%). Women pregnant with a singleton after a previous preterm twin pregnancy have an absolute recurrence risk of 10% (95% CI 8.2–12.3%), whereas a singleton pregnancy after delivering a previous twin up to term yields a low absolute risk of only 1.3% (95% CI 0.8–2.2). Women pregnant with a singleton after a previous preterm singleton have an absolute recurrence risk of 20% (95% CI 19.9–20.6).Author's conclusionsThe risk of recurrence of preterm birth is influenced by the singleton/twin order in both pregnancies, and varies between 10% for a singleton after previous preterm twins to 57% for twins after a previous preterm singleton.
Imagining the Child: Bad Parents in the Mid‐Eighteenth‐Century English Novel
Authors: Paxman David B. 
Published: June 2014

AbstractThe British novel's history is partly one of discovering the child. Novels of the 1720s depict neglected or abandoned children as a backdrop for adventure and scandal. Three mid‐century novels illustrate the growing interest in generational thinking (a concern for children's welfare and future). In Richardson's Clarissa, the Harlowes' rigid authority blinds them from ‘recognising’, in Ricoeur's sense, Clarissa. In Tom Jones, Fielding shows a deep interest in generational thinking, which guides even Bridget Allworthy, in spite of her other hypocrisies. In Haywood's Betsy Thoughtless, Betsy faces constant moral risk because her surrogate parents ignore or misperceive her developmental needs.
Log odds of positive lymph nodes are superior to other measures for evaluating the prognosis of non‐small cell lung cancer
Authors: Lv Peng , Chen Gang , Zhang Peng 
Published: June 2014

AbstractBackgroundTo evaluate the ability of the log odds of positive lymph nodes to predict prognosis in patients with non‐small cell lung cancer (NSCLC).MethodsCorrelations between the log odds of positive lymph nodes, numbers of dissected lymph nodes, dissected lymph node stations, positive lymph nodes, positive lymph node ratio, and positive lymph node stations were retrospectively evaluated using Pearson correlation coefficients (r), survival analysis by Kaplan–Meier, Cox hazard ratio model, and log‐rank tests.ResultsThe numbers of dissected lymph nodes, positive lymph nodes, dissected lymph node stations and positive lymph node stations significantly correlated with the log odds of positive lymph nodes (P < 0.001, P < 0.001, P = 0.002 and P < 0.001, respectively). The five‐year survival ratio of postoperative patients with the log odds of positive lymph nodes <11.412 and >−1.412 were 63.9% and 32.5%, respectively (P < 0.001). According to multivariate analysis, age and log odds of positive lymph nodes are independent risk factors for overall survival (hazard ratio = 2.660, 95% confidence interval 2.114–3.346, P < 0.001). A new staging system featuring a combination of log odds of positive lymph nodes and a tumor node metastasis (TNM) staging system was established for predicting survival.ConclusionThe log odds of positive lymph nodes are superior to the positive lymph node ratio and p‐N‐stage for predicting prognosis of NSCLC. A new staging system that combines log odds of positive lymph nodes and the current TNM staging system predicts prognosis more accurately than the TNM system alone.

The effect of continuous popliteal sciatic nerve block on unplanned postoperative visits and readmissions after foot surgery – a randomised, controlled study comparing day‐care and inpatient management
Authors: Saporito A. , Sturini E. , Borgeat A. , Aguirre J. 
Published: June 2014

SummaryRegional anaesthesia has been shown to have several advantages over general anaesthesia in reducing the need for, and hence cost of, unscheduled outpatient visits or readmission to hospital. However, the benefit has not been evaluated in a direct comparison between day‐care patients and inpatients. We randomly allocated 120 patients undergoing unilateral foot surgery to either inpatient (two‐day postoperative stay) or day‐care management under continuous regional anaesthesia, and compared the impact on unscheduled postoperative outpatient visits, readmissions to hospital and the associated costs. The operations were performed under popliteal sciatic nerve block. A perineural catheter was inserted before surgery and removed from all patients on the third postoperative day. We found no significant difference in the incidence of outpatient visits (3.3% day‐care vs 5.0% inpatient, p = 0.640), readmissions (6.7% day‐care vs 3.3% inpatient, p = 0.395) or complications between the two groups. Costs were also significantly lower in the day‐care group (net difference €8011 (£6684; $10 986) per patient, p < 0.001). We conclude that continuous regional anaesthesia allows foot surgery to be performed as a day‐care procedure more cheaply than in inpatients, without an increase in clinical complications.
Case series of elective instrumented posterior lumbar spinal fusions demonstrating a low incidence of venous thromboembolism
Authors: Weber Benjamin , Seal Alexa , McGirr Joe , Fielding Kerin 
Published: June 2014

AbstractBackgroundVenous thromboembolism (VTE) is a significant cause of morbidity and mortality in orthopaedic surgery. While specific guidelines exist for hip and knee arthroplasty, there is wide variation in VTE prophylaxis in complex spinal surgery. This study sought to determine the incidence of VTE, and risk factors associated with VTE, in patients undergoing elective instrumented posterior lumbar spinal fusion.MethodsIn a single‐centre case series study, 107 consecutive patients undergoing elective lumbar spinal fusion were evaluated for VTE by lower limb duplex ultrasonography and/or clinical observation, and where indicated, computed tomography pulmonary angiogram. The Caprini model for thrombosis risk factor assessment was retrospectively applied to grade levels of VTE risk, which were compared with overall VTE incidence.ResultsAll patients were operated on a spinal frame and received mechanical prophylaxis (thromboembolic deterrent stockings and sequential calf‐compression devices). Thirty‐seven per cent also received chemoprophylaxis with low‐molecular‐weight heparin (LMWH). There was no significant relationship between LMWH use and protection from VTE. Risk scores ≥3 (high/highest risk categories) were observed in 96.2% of patients. Four (3.7%) patients encountered a VTE complication (all with no chemoprophylaxis), either deep vein thrombosis (1.9%) or pulmonary embolism (1.9%). No patients sustained an epidural haematoma.ConclusionAlthough patients undergoing elective instrumental posterior lumbar spinal fusion are at high risk of developing VTE, the actual incidence of VTE in these patients is low. Our data support the use of mechanical prophylaxis with thromboembolic deterrent stockings and sequential calf‐compression devices to prevent VTE in these patients.
