Published: March 2011

BackgroundCurrent theories of post-traumatic stress disorder (PTSD) place considerable emphasis on the role cognitive distortions such as self-blame, hopelessness or preoccupation with danger play in the etiology and maintenance of the disorder. Previous studies have shown that cognitive distortions in the early aftermath of traumatic events can predict future PTSD severity but, to date, no studies have investigated the neural correlates of this association.MethodWe conducted a prospective study with 106 acutely traumatized subjects, assessing symptom severity at three time points within the first 3 months post-trauma. A subsample of 20 subjects additionally underwent a functional 4-T magnetic resonance imaging (MRI) scan at 2 to 4 months post-trauma.ResultsCognitive distortions proved to be a significant predictor of concurrent symptom severity in addition to diagnostic status, but did not predict future symptom severity or diagnostic status over and above the initial symptom severity. Cognitive distortions were correlated with blood oxygen level-dependent (BOLD) signal strength in brain regions previously implicated in visual processing, imagery and autobiographic memory recall. Intrusion characteristics accounted for most of these correlations.ConclusionsThis investigation revealed significant predictive value of cognitive distortions concerning concurrent PTSD severity and also established a significant relationship between cognitive distortions and neural activations during trauma recall in an acutely traumatized sample. These data indicate a direct link between the extent of cognitive distortions and the intrusive nature of trauma memories.
Cross-cultural gerontology research methods: challenges and solutions
Authors: CHI IRIS 
Published: March 2011

ABSTRACTCross-cultural research in the behavioural and social sciences uses data from several societies or distinct cultural groups to describe the diversity of human behaviour and test hypotheses about behaviour and culture. This paper reviews the historical development and current state of cross-cultural research in the social sciences and gerontology. Cross-cultural research in gerontology is important because the social processes of ageing vary. It aims to distinguish universal from culturally-specific processes and determine how cultural factors influence individual and population ageing. It has to overcome many challenges: how to design an equivalent and unbiased study, how to access different cultures, how to contextualise these cultures, and how to ensure that questions are meaningful for different cultures. Appropriate strategies include using an international multicultural research team, becoming familiar with the local culture, maintaining good relationships with community leaders, studying only those aspects of behaviour that are functionally equivalent while avoiding the idiosyncratic, using appropriate measures, and encouraging equal partnership and open communication among colleagues. Cross-cultural research has been growing and has become a basis for globally-relevant social gerontology. To highlight the complexity of cross-cultural research and lessons learnt from such research experience, this paper describes an example study of long-term care that involved researchers from more than 30 countries and from many disciplines.
Experiences in the development of a teleoperated parallel robot for aerial line maintenance
Authors: Garcia Cecilia , Saltaren Roque , Aracil Rafael 
Published: March 2011

SUMMARYThis paper presents the teleoperation of a parallel robot based on the Stewart–Gough platform. The robot is an experimental prototype capable of sliding along electrical lines in order to carry out different inspection and maintenance tasks. The paper also describes the kinematic equations of the parallel robot and their solution. The teleoperation of the prototype took place in a testing bank developed in the laboratory and containing the basic elements of electrical lines. The operator who performs the task uses a six degrees-of-freedom master-arm with force reflection, which also has an image-viewing system providing the operator with stereoscopic vision and allowing him/her to calibrate the information of the local station simulator with the real environment through the blending of images. The paper also presents the results of the laboratory experiments of the robot sliding along a line.
Interdisciplinary research and academic sustainability: managing knowledge in an age of accountability
Authors: FRODEMAN ROBERT 
Published: March 2011

SUMMARYFor the past 125 years the university has been the home of knowledge production. The 20th century research university combined a Kantian belief in disciplinarity, a Humboldtian commitment to linking research and education and upholding academic autonomy, and a Cartesian allegiance to infinite knowledge production. This approach to knowledge creation was seen as sufficient, for knowledge products themselves were understood as automatically relevant to society, and no one imagined a problem with endless knowledge production. The 20th century model of knowledge production is now under pressure from a number of sources: information technologies, neoliberal assumptions and demands for greater accountability. ‘Interdisciplinarity’ has become the term of art for addressing this crisis. But interdisciplinarity is no panacea to the challenges facing knowledge production today. In addition to knowledge on sustainability, knowledge production itself must now be made sustainable. This requires clearly connecting knowledge production and use, and ending the bad infinity of knowledge production.
A simple correctness proof for magic transformation
Authors: DRABENT WŁODZIMIERZ 
Published: March 2011

AbstractThe paper presents a simple and concise proof of correctness of the magic transformation. We believe that it may provide a useful example of formal reasoning about logic programs. The correctness property concerns the declarative semantics. The proof, however, refers to the operational semantics (LD-resolution) of the source programs. Its conciseness is due to applying a suitable proof method.
Adaptive Support Ventilation May Deliver Unwanted Respiratory Rate–Tidal Volume Combinations in Patients with Acute Lung Injury Ventilated According to an Open Lung Concept
Authors: Dongelmans Dave A. , Paulus Frederique , Veelo Denise P. , Binnekade Jan M. , Vroom Margreeth B. , Schultz Marcus J. 
Published: March 2011

Background
With adaptive support ventilation, respiratory rate and tidal volume (V(T)) are a function of the Otis least work of breathing formula. We hypothesized that adaptive support ventilation in an open lung ventilator strategy would deliver higher V(T)s to patients with acute lung injury.

Methods
Patients with acute lung injury were ventilated according to a local guideline advising the use of lower V(T) (6-8 ml/kg predicted body weight), high concentrations of positive end-expiratory pressure, and recruitment maneuvers. Ventilation parameters were recorded when the ventilator was switched to adaptive support ventilation, and after recruitment maneuvers. If V(T) increased more than 8 ml/kg predicted body weight, airway pressure was limited to correct for the rise of V(T).

Results
Ten patients with a mean (±SD) Pao(2)/Fio(2) of 171 ± 86 mmHg were included. After a switch from pressure-controlled ventilation to adaptive support ventilation, respiratory rate declined (from 31 ± 5 to 21 ± 6 breaths/min; difference = 10 breaths/min, 95% CI 3-17 breaths/min, P = 0.008) and V(T) increased (from 6.5 ± 0.8 to 9.0 ± 1.6 ml/kg predicted body weight; difference = 2.5 ml, 95% CI 0.4-4.6 ml/kg predicted body weight, P = 0.02). Pressure limitation corrected for the rise of V(T), but minute ventilation declined, forcing the user to switch back to pressure-controlled ventilation.

Conclusions
Adaptive support ventilation, compared with pressure-controlled ventilation in an open lung strategy setting, delivers a lower respiratory rate-higher V(T) combination. Pressure limitation does correct for the rise of V(T), but leads to a decline in minute ventilation.
Perioperative β-Blockade
Authors: Wallace Arthur W. , Au Selwyn , Cason Brian A. 
Published: March 2011

Background
The Atenolol study of 1996 provided evidence that perioperative β-blockade reduced postsurgical mortality. In 1998, the indications for perioperative β-blockade were codified as the Perioperative Cardiac Risk Reduction protocol and implemented at the San Francisco Veterans Affairs Medical Center. The current study tested the following hypothesis: Is there a difference in mortality rates between patients receiving perioperative atenolol and metoprolol?

Methods
Epidemiologic analysis of the operations performed at the San Francisco Veterans Affairs Medical Center since 1996 was performed. High-risk inpatients with perioperative β-blockade were divided into two groups: patients who received perioperative atenolol only and those who received metoprolol only. Patients who switched between the two chronic oral β-blocker medications were excluded. IV administration of β-blockers was ignored. Propensity matching analysis was used to correct for population differences in risk factors.

Results
There were 38,779 operations performed from 1996 to 2008, with 24,739 inpatient procedures. Based on analysis of inpatient medication use, 3,787 patients received atenolol only (1,011) or metoprolol only (2,776). Thirty-day mortality (atenolol 1% vs. metoprolol 3%, P < 0.0008) and 1-yr mortality (atenolol 7% vs. metoprolol 13%, P < 0.0001) differed between the two β-blockers. Analysis based on inpatient and outpatient β-blocker use showed a similar pattern. Propensity matching that corrected for multiple cardiac risk factors found an odds ratio (OR) of 2.1 [95% CI 1.5-2.9], P < 0.0001 for increased 1-yr mortality with metoprolol for inpatient use.

Conclusion
Perioperative β-blockade using atenolol is associated with reduced mortality compared with metoprolol.

Published: March 2011

PurposeThe purpose of this paper is to develop and optimize anti‐corrosive multi‐layered coatings of zinc‐nickel alloy on carbon steel.Design/methodology/approachA variety of composition‐modulated multi‐layer alloy (CMMA) coatings of zinc‐nickel were developed on a carbon steel substrate by cyclic changes in cathode current during electrodeposition, coupled with variation of the thicknesses of the individual layers. The corrosion behavior of the coatings was studied in 5 percent NaCl solution by electrochemical methods. Cyclic cathode current densities (CCCDs) and the number of alloy layers were optimized for highest performance of the coatings against corrosion. The factors responsible for improved corrosion resistance were analyzed in terms of change in the intrinsic electrical properties of the capacitance value at the electrical double layer that was associated with micro/nanometric layering. The formation of the semi‐conductive surface film, which was responsible for the improved corrosion resistance, was supported by a Mott‐Schottky plot and the cyclic polarization study. The formation of multi‐layered deposit and the mechanism of corrosion degradation of the coating were analyzed using scanning electron microscopy.FindingsCMMA coatings with an optimal configuration of (Zn‐Ni)2.0/4.0/300 showed ∼35 times better corrosion resistance compared to a monolithic (Zn‐Ni)3.0 alloy coating of the same thickness. The peak performance was attributed to the change in intrinsic electrical properties of the coating and this conclusion was supported by dielectric spectroscopy.Originality/valueThe paper describes the optimization of CCCD and the number of deposited layers by development of electrolytic deposition of anti‐corrosive multi‐layered zinc‐nickel coatings from a single plating technique.
Analyzing and forecasting the reliability for repairable systems using the time series decomposition method
Authors: Liang Yi‐Hui 
Published: March 2011

PurposeThe purpose of this study is to propose the time series decomposition approach to analyze and predict the failure data of the repairable systems.Design/methodology/approachThis study employs NHPP to model the failure data. Initially, Nelson's graph method is employed to estimate the mean number of repairs and the MCRF value for the repairable system. Second, the time series decomposition approach is employed to predict the mean number of repairs and MCRF values.FindingsThe proposed method can analyze and predict the reliability for repairable systems. It can analyze the combined effect of trend‐cycle components and the seasonal component of the failure data.Research limitations/implicationsThis study only adopts simulated data to verify the proposed method. Future research may use other real products' failure data to verify the proposed method. The proposed method is superior to ARIMA and neural network model prediction techniques in the reliability of repairable systems.Practical implicationsResults in this study can provide a valuable reference for engineers when constructing quality feedback systems for assessing current quality conditions, providing logistical support, correcting product design, facilitating optimal component‐replacement and maintenance strategies, and ensuring that products meet quality requirements.Originality/valueThe time series decomposition approach was used to model and analyze software aging and software failure in 2007. However, the time series decomposition approach was rarely used for modeling and analyzing the failure data for repairable systems. This study proposes the time series decomposition approach to analyze and predict the failure data of the repairable systems and the proposed method is better than the ARIMA model and neural networks in predictive accuracy.
The relationships between supply chain and firm performance
Authors: Johnson Mark , Templar Simon 
Published: March 2011

PurposeSupply chains directly influence the differentiation and cost of a firm's products and services and its exposure to risk. The purpose of this paper is to use secondary financial data to explore the relationship between supply chain and firm performance by developing a unified proxy for supply chain performance.Design/methodology/approachEstablished econometric techniques were used to validate the proxy using a sample frame comprising the annual reports of 117 publicly traded UK manufacturing firms from the period 1995 to 2004.FindingsIncreases in change in the proxy lead to an increase in change in the rate of return on capital employed and a change in the rate of cash‐to‐cash cycle length, both of which are traditional measures of improved supply chain management. Moreover, as the rate of change of the proxy increases, so does enterprise value at a level that is statistically significant, indicating that improving supply chain management practices has a positive impact upon improved firm performance.Research limitations/implicationsAs annual financial results were used the analysis is at a high level so there is a lack of resolution in identifying discrete causes. The use of annual financial results also means that the research can only take yearly snapshots of firm performance.Practical implicationsThe paper indicates that the supply chain is an enabler, not an impediment, to superior organisational performance.Originality/valueThe originality and value of this paper is that it develops a proxy to explain the relationships between supply chain and an organisation's financial performance taking into account the three imperatives of profitability, liquidity, and productivity.
Study of sharing knowledge resources in business schools
Authors: Ranjan Jayanthi 
Published: March 2011

PurposeThe purpose of this paper is to propose a common business school framework based on knowledge resources that are available in business schools. To support the arguments made based on review literature, the paper presents the holistic framework of knowledge resources in a business school and also provides a knowledge value chain in sharing the resources. The paper then applies the framework to study the provisions of knowledge recourses in a business school to examine the effect of knowledge sharing.Design/methodology/approachDrawing on insights from review literature the paper starts from a broad view on knowledge sharing in business schools. Then the paper proposes a knowledge‐sharing framework. To evaluate the framework, the paper investigates one of the business school's knowledge sharing tools. Wherever data were insufficient, logical interpretation is provided. The framework is compared with respect to business schools. Then it is analyzed with the business school's online knowledge sharing tool.FindingsThe paper finds that the rapid pace of change in knowledge resources is increasingly influencing the creation, publication and dissemination of educational materials and sharing information – thus, finally having an impact on learning. The paper finds that there is an urgent need to share all the knowledge resources in business schools for effective delivery. Some important general observations are argued for, while studying the online knowledge‐sharing tool. First, effective information technology infrastructure for sharing knowledge resources is a must, and second, all the resources need to be shared online. The paper finds that the purpose of knowledge sharing in business schools would create value in the form of academic and personal value.Originality/valueThe paper provides useful suggestions for business schools to adopt knowledge‐sharing tools. The framework proposed can be adopted by any business school worldwide to enhance their ratings and processes. The paper reveals through study that, business schools must actively explore the immense potential and the wide ramifications of the knowledge resources that are hidden in different academic domains rather than just waiting to adopt passively some tool at different academic domains. This paper sets out to inspire business school leaders to find out more on knowledge sharing tools. The chosen research strategy was to study business schools and analyze their content, looking for similarities and complementarities in their nature and their strategies with respect to knowledge sharing. First, the paper identified existing systems, examining available processes in the business school, and expanding them through more searches. This paper is based on reflections combined with inputs from informal discussions and interviews conducted with several management educators, management consultants, management students and managers, which had taken place at several meetings, seminars and conferences over the last few years.
The speed of knowledge transfer within multinational enterprises: the role of social capital
Authors: Chen Jiun‐Shiu , Lovvorn Al S. 
Published: March 2011

PurposeThe success of knowledge transfer very much depends on a company's ability to effectively manage their knowledge transfer process. The purpose of this paper is to argue that a critical component in understanding knowledge transfer in the international arena is the speed of that knowledge transfer (and those factors that influence that speed) within a multinational enterprise (MNE).Design/methodology/approachIn this paper, social capital theory is used to argue that social capital is related to the speed of knowledge transfer within an MNE. The three dimensions of social capital, i.e. relational, dimensional, and cognitive, facilitate the transfer process and effect the rapidity of technology transfer.FindingsThe role of knowledge transfer speed in MNEs knowledge management has been neglected and, yet, the speed of knowledge transfer is critical for MNE organizations to build or maintain their competitive advantage. A critical component in understanding knowledge transfer in the international arena is the speed of that knowledge transfer (and those factors that influence that speed) between different units.Originality/valueThis study examines social capital to better understand knowledge management at the intra‐firm level of an MNE. The success of knowledge transfer very much depends on a company's ability to effectively manage that knowledge transfer process. Using social capital theory, we argued that the three dimensions of social capital (relational, dimensional, and cognitive) are related to the speed of knowledge transfer from the parent company to the foreign subsidiary.
Turnover intentions
Authors: Wells Janelle E. , Welty Peachey Jon 
Published: March 2011

PurposeThis paper aims to investigate the relationship between leadership behaviors (transformational and transactional), satisfaction with the leader, and voluntary turnover intentions. In particular, it aims to investigate the mediation effect of satisfaction with the leader on the relationship between leadership behaviors and voluntary turnover organizational intentions.Design/methodology/approachParticipants were 208 National Collegiate Athletic Association (NCAA) Division I softball and volleyball assistant coaches in the USA. Using the multifactor leadership questionnaire (MLQ – Form 5X) and an organizational turnover intent questionnaire, participants evaluated their head coach's leadership behavior, satisfaction with the leader, and their own organizational turnover intent.FindingsResults revealed a direct negative relationship between leadership behaviors (transformational and transactional) and voluntary organizational turnover intentions. Also, satisfaction with the leader mediated the negative relationship between leadership behaviors (transformational and transactional) and voluntary turnover intentions.Research limitations/implicationsThe study was limited by the use of professional associations to contact participants, the timing of the data collection, and the exploration of only one of numerous possible mediating variables. Several management implications are discussed, such as managers recognizing that both leadership behaviors can be the basis for effective leadership of work teams and for mitigating voluntary turnover intentions.Originality/valueThe paper's principal theoretical contribution is the addition of satisfaction with the leader as a mediating variable between transformational and transactional leadership behavior and voluntary organizational turnover intentions.
