Infants’ Preferential Attention to Sung and Spoken Stimuli
Authors: Costa-Giomi Eugenia , Ilari Beatriz
Published: May 2014

Caregivers and early childhood teachers all over the world use singing and speech to elicit and maintain infants’ attention. Research comparing infants’ preferential attention to music and speech is inconclusive regarding their responses to these two types of auditory stimuli, with one study showing a music bias and another one indicating no differential attention. The purpose of this investigation was to study 11-month-old infants’ preferential attention to spoken and sung renditions of an unfamiliar folk song in a foreign language ( n = 24). The results of an infant-controlled preference procedure showed no significant differences in attention to the two types of stimuli. The findings challenge infants’ well-documented bias for speech over nonspeech sounds and provide evidence that music, even when performed by an untrained singer, can be as effective as speech in eliciting infants’ attention.
Modeling and simulation of the industrial numerical distance relay aimed at knowledge discovery in resident event reporting
Authors: Othman Mohammad Lutfi , Aris Ishak , Wahab Noor Izzri Abdul
Published: May 2014

In the motivation of tapping the strong potential of computational intelligence in discovering knowledge of protective relay operations using data mining, modeling and simulation of an actual industrial numerical distance relay and its recording facility are a vital requisite. This is justified by the practicality and necessity of divulging the decision algorithm hidden in the recorded relay event report using computational intelligence-based data mining. Thus, this paper studies the detailed modeling and simulation of an industrial AREVA MiCOM P441 distance relay, accommodated together with its own simulated event report recording facility. The idea is to provide the flexibility of allowing the simulated event report to have sufficiently significant depth and breadth for data mining purposes. The modeled relay has operated correctly and discriminatively in deciding circuit breaker pole(s) to be tripped in stipulated assertion times as per the Malaysian licensee’s requirements for various faults and protected zones along a transmission line. It has subsequently been validated successfully by the performance of the real field AREVA MiCOM P441 distance relay belonging to the Malaysian licensee. With the successful modeling and simulation of the AREVA MiCOM P441 distance relay and its recording facility, such subsequent works as data extraction and preparation, computational intelligence-based data mining for relay decision algorithm discovery and finally a relay analysis expert system development can certainly be executed. These subsequent applications are briefly explored as a demonstration of the benefit offered after the successful modeling of the relay.
The Unity of Salvation: Divine Missions, the Church, and World Religions
Authors: Jacobs-Vandegeer Christiaan
Published: May 2014

The author addresses the doctrinal affirmations of the universality of God’s salvific will and the necessity of the church for salvation. Jacques Dupuis and Gavin D’Costa propose distinct ways of reconciling them; comparing their proposals illustrates the challenge that contemporary Catholic theology faces in its current context of religious pluralism. The author appeals to Bernard Lonergan’s work to suggest an alternative that both anticipates the presence of God outside the church and simultaneously affirms the necessity of the church for the salvation of all.
The Spiritual Exercises as an Ecumenical Strategy
Authors: Haight Roger
Published: May 2014

The ecumenical movement, proceeding comparing doctrines and ecclesial structures that divide, has foundered. The article suggests turning to what all churches share in common as a new starting point, namely, an ecclesial spirituality of following Jesus. The Spiritual Exercises of Ignatius Loyola can help bring this bond of unity to the surface. Negotiating on the basis of this common possession will allow the ideal of a pluralistic unity to take hold and encourage ecclesial structures that protect and honor rather than exclude different church traditions.
Can Catholic Social Teaching Bring Peace to the “Liturgy Wars”?
Authors: Jeffery Peter
Published: May 2014

A way past the “liturgy wars” opens up if we view contemporary liturgy from the perspective of Catholic social teaching. Freedom of conscience and worship requires toleration of diverse theories of liturgy. Respect for the dignity of the human person foregrounds Vatican II’s fundamental teaching that active participation is the primary and indispensable source of the true Christian spirit. The right to culture signals the importance of culturally informed liturgical formation. In this way the “liturgy wars” can be reinterpreted as illustrating Congar’s dialectical understanding of ecclesiastical tradition.
Self-Expressiveness in Sport Tourism
Authors: Bosnjak Michael , Brown Carroll A. , Lee Dong-Jin , Yu Grace B. , Sirgy M. Joseph
Published: May 2014

This study develops and tests a model of self-expressiveness in sport tourism, defined as the extent to which a tourist perceives that a sport activity is reflective of his or her personal identity. Self-expressiveness in a sport activity experienced by a tourist should depend on the activity’s perceived difficulty, perceived effort, perceived importance, and potential for self-realization. In turn, a tourist’s self-expressiveness in a sport activity should exert a positive influence on the tourist’s experience of personal happiness (subjective well-being). The results of two surveys involving 1,251 travelers who participated in a dance festival (study 1) and ski activities (study 2) during their vacations confirm the hypotheses, revealing several interesting theoretical and managerial implications.
Moral Identity as a Moderator of the Effects of Organizational Injustice on Counterproductive Work Behavior Among Chinese Public Servants
Authors: Mingzheng Wu , Xiaoling Sun , Xubo Fu , Youshan Liu
Published: May 2014

Despite the considerable research to investigate the influence of organizational injustice on employees’ counterproductive work behaviors (CWB), relatively little attention has been paid to the role of moral identity. In the present study, we posit that people’s moral identity serves as a buffering factor between organizational injustice and CWB among Chinese public servants. Consistent with the hypotheses, survey results showed that organizational justice and moral identity interacted to influence Chinese public servants’ CWB. Specifically, when the moral identity of Chinese public servants was low, the negative correlation between organizational justice and CWB was more pronounced. Theoretical implications to the moral identity and organizational injustice literature are discussed, as well as the practical implications and suggestions for future research.
A robust H-infinity controller design approach for neutral systems with time-varying delay and plant and controller uncertainties
Authors: Parlakçı Mehmet Nur Alpaslan
Published: May 2014

This paper is concerned with a state feedback controller design method for neutral systems with a time-varying delay, considering uncertainties in the plant parameters, as well as in controller gain. The uncertainties are in additive form, affecting both the system matrices of the plant and the controller gain. The uncertainties that are assumed admissible are time-varying and norm-bounded. The neutral system is also subject to external disturbances. A robust stabilizing H-infinity state-feedback controller is synthesized under several conditions that are presented in the form of matrix inequalities. A new generalized type of Jensen integral inequality has been introduced for utilization in the derivation of the aforementioned results, which could thus have been relaxed via that approach. A feasible solution set is obtained using the well-known cone complementarity technique by solving a non-linear minimization problem subject to linear matrix inequalities. A numerical example with case studies concludes the present work. The results of the minimum achievable attenuation rate indicate considerable improvement in comparison with those reported in the literature.
Finite-time hybrid projective synchronization of unified chaotic system
Authors: Wei Qiang , Wang Xing-yuan , Hu Xiao-peng
Published: May 2014

This paper presents finite-time hybrid projective synchronization for the unified chaotic system. The significant contribution of this paper is that master–slave system realizes hybrid projective synchronization within a pre-specified convergence time. Base on the Lyapunov stability theory and finite-time stability theory, a finite-time controller is derived to make the state of the slave system exponentially synchronize the state of the master system, and the different components of state of the slave system and the master system synchronize up to different desired scaling constant. Numerical simulations are presented to show the effectiveness of theoretical analysis.
State feedback control for a class of stochastic high-order feedforward nonlinear systems with time-varying delays: a homogeneous domination approach
Authors: Jiao Ticao , Cui Guozeng , Lu Junwei , Ma Qian
Published: May 2014

In this paper, the problem of global state feedback stabilization for a class of stochastic high-order feedforward nonlinear systems with different power orders and multiple time delays is investigated. A distinct property of the system to be investigated is that the control coefficients are not restricted to 1. By adding one power integrator technique and homogeneous domination approach, a state feedback controller design is recursively proposed, which ensures the global asymptotical stability in probability of the closed-loop system. Finally, a simulation example is given to illustrate the effectiveness of our results obtained in this paper.
Robust estimator-based optimal control designs for U-tube steam generators
Authors: Ablay Günyaz
Published: May 2014

U-tube steam generator level control systems are used to maintain the water level within prescribed narrow limits and to provide constant supply of high-quality steam during power demand variations. Traditional level control systems are often found to be unsatisfactory during low power operations and start-up conditions. Robust non-linear estimator-based optimal control systems are proposed for steam generator level control systems to solve the water level tracking problem during power (or steam) demand variations. It is shown that the proposed control strategies provide optimal and robust water level tracking with a single controller over the complete range of power operation with model and parameter uncertainties and noisy measurements.
Adaptive hybrid complex projective synchronization of chaotic complex system
Authors: Wei Qiang , Wang Xing-yuan , Hu Xiao-peng
Published: May 2014

In this paper defines an adaptive hybrid complex projective synchronization method to synchronize two chaotic complex systems. Base on Lyapunov stability theory, the adaptive control law and parameter update law are derived to make the state of two chaotic complex systems, which are adaptive hybrid complex projective synchronized. This paper extends projective synchronization from the field of real numbers to the field of complex numbers for a chaotic complex system. Different components of the complex system synchronized to different scale complex numbers. Numerical simulations are presented to demonstrate the effectiveness of the proposed adaptive controllers.
Modalities, motivations, and materials – investigating traditional and social online Q&A services
Authors: Shah Chirag , Kitzie Vanessa , Choi Erik
Published: May 2014

With the advent of ubiquitous connectivity and a constant flux of user-generated content, people’s online information-seeking behaviours are rapidly changing, one o f which includes seeking information from peers through online questioning. Ways to understand this new behaviour can be broken down into three aspects, also referred to as the three M’s – the modalities (sources and strategies) that people use when asking their questions online, their motivations behind asking these questions and choosing specific services, and the types and quality of the materials (content) generated in such an online Q&A environment. This article will provide a new framework – three M’s – based on the synthesis of relevant literature. It will then identify some of the gaps in our knowledge about online Q&A based on this framework. These gaps will be transformed into six research questions, stemming from the three M’s, and addressed by (a) consolidating and synthesizing findings previously reported in the literature, (b) conducting new analyses of data used in prior work, and (c) administering a new study to answer questions unaddressed by the pre-existing and new analyses of prior work.
Enhancing the popular music ensemble workshop and maximising student potential through the integration of creativity
Authors: Hall Richard
Published: May 2014

Ensemble work is a key part of any performance-based popular music course and involves students replicating existing music or playing ‘covers’. The creative process in popular music is a collaborative one and the ensemble workshop can be utilised to facilitate active learning and develop musical creativity within a group setting. This is a report on a reflection into the practice of the ensemble workshops within the author’s own further education context. It is proposed that in order to unlock creative potential, develop active group learning and add value to the student, a new approach to pedagogy within ensemble work is required. This approach involves scaffolding learning through the setting of collaborative, creative tasks and provision of a mentoring environment in which students can feel safe to experiment.
From Learning to Knowing: A Psychological–Neurological Approach to Explain the Human Capital Formation Process
Authors: Tamilina Larysa , Tamilina Natalya
Published: May 2014

By drawing on neurological and psychological theories of learning, our study introduces a new conceptual framework to analyze the role that learning plays in knowledge and skill acquisition. Learning is modelled through four mechanisms defined as individuals’ participation in formal, non-formal and informal learning as well as learning-by-doing. Our analysis demonstrates heterogeneity in how various learning mechanisms affect people’s overall stock of human capital. Additionally, the proposed analytical framework points to the existence of complementarity between the four learning forms and suggests that participation in all of them is needed to maximize the process of human capital formation. These propositions are tested empirically with the Adult Literacy and Life Skills Survey data (2003) utilizing a variety of statistical techniques.

The Nature of the Business Group: Power, Relational Contracts and Scope
Authors: Kali Raja
Published: May 2014

We propose a framework for understanding the business group, a hybrid organizational form that occupies the middle ground between firm and market and is a prominent feature of emerging economies. These organizations are characterized by varying levels of diversification and integration. We provide an explanation for the covariation, both positive and negative, in the scope, scale and ‘strength’ of integration of business groups. This notion of integration embodies the strength of ties that connect disparate subsidiary activities to the core of the business group, and is, we believe, novel to the theory of the firm. We also suggest the framework may be useful for understanding internal organizational hierarchy and multiproduct firms.

Predictive Modeling of Implantation Outcome in an In Vitro Fertilization Setting
Authors: Uyar Asli , Bener Ayse , Ciray H. Nadir
Published: May 2014

Background. Multiple embryo transfers in in vitro fertilization (IVF) treatment increase the number of successful pregnancies while elevating the risk of multiple gestations. IVF-associated multiple pregnancies exhibit significant financial, social, and medical implications. Clinicians need to decide the number of embryos to be transferred considering the tradeoff between successful outcomes and multiple pregnancies. Objective. To predict implantation outcome of individual embryos in an IVF cycle with the aim of providing decision support on the number of embryos transferred. Design. Retrospective cohort study. Data Source. Electronic health records of one of the largest IVF clinics in Turkey. The study data set included 2453 embryos transferred at day 2 or day 3 after intracytoplasmic sperm injection (ICSI). Each embryo was represented with 18 clinical features and a class label, +1 or -1, indicating positive and negative implantation outcomes, respectively. Methods. For each classifier tested, a model was developed using two-thirds of the data set, and prediction performance was evaluated on the remaining one-third of the samples using receiver operating characteristic (ROC) analysis. The training-testing procedure was repeated 10 times on randomly split (two-thirds to one-third) data. The relative predictive values of clinical input characteristics were assessed using information gain feature weighting and forward feature selection methods. Results. The naïve Bayes model provided 80.4% accuracy, 63.7% sensitivity, and 17.6% false alarm rate in embryo-based implantation prediction. Multiple embryo implantations were predicted at a 63.8% sensitivity level. Predictions using the proposed model resulted in higher accuracy compared with expert judgment alone (on average, 75.7% and 60.1%, respectively). Conclusions. A machine learning–based decision support system would be useful in improving the success rates of IVF treatment.
Reduce, Reuse, Recycle … and Refuse
Authors: Benton Raymond
Published: May 2014

Two recent books, both by journalists, expose major weaknesses in marketing because of what is ignored in the standard treatment. The marketing story tends to end with the purchase of a good or service. But what is bought is eventually discarded and what happens when goods are thrown away is part of the marketing system, too. This part of the system is largely ignored. How much we actually throw away is alarming, mostly because we are unaware of it. Some of it enters the global recycling industry, but the vast majority goes into the trash sector. It may or may not actually get land filled. It may just float around in the oceans. We did not get to where we are by accident. Marketing and marketers helped in a big way. Macromarketers must help us understand the predicament we are in, and then help get us out of it.
Expression of eukaryotic initiation factor 4 E in hypopharyngeal carcinoma
Authors: Han Min , Wang Wei , Wang Lin , Jiang Yan
Published: May 2014

Objectives

To investigate the expression of eukaryotic initiation factor 4 E (eIF4E) in hypopharyngeal carcinoma compared with benign lesions, and the relationships between eIF4E expression and various clinicopathological parameters.

Methods

Expression of eIF4E was analysed retrospectively in specimens from hypopharyngeal carcinomas and benign hypopharyngeal lesions using immunohistochemical staining and Western blotting. Tumours were classified using the tumour–node–metastasis staging system and the degree of histological differentiation was assessed.

Results

A total of 55 hypopharyngeal carcinoma and 20 benign specimens were analysed. All the hypopharyngeal carcinoma samples were positive for eIF4E expression on immunohistochemistry, whereas the benign lesions were negative or weakly positive. Semi-quantitative assessment (eIF4E score) showed that eIF4E expression was significatly higher in hypopharyngeal carcinoma than in benign lesions. On Western blotting, eIF4E expression assessed using integrated optical density (IOD) was significantly higher in hypopharyngeal carcinoma than in benign lesions. The eIF4E score and IOD value were significantly associated with tumour stage, lymphatic metastasis and degree of differentiation. The IOD value was significantly higher in recurrent compared with initial cases.

Conclusions

eIF4E may play an important role in the development and metastasis of hypopharyngeal carcinoma;its expression may be helpful in establishing the diagnosis, stage and prognosis of this tumour type.
Immunohistochemical Characterization and Morphometric Analysis of Macrophages in Rat Mammary Tumors
Authors: Ong C. B. , Brandenberger C. , Kiupel M. , Kariagina A. , Langohr I. M.
Published: May 2014

Macrophages are an important leukocyte component of the microenvironment of neoplasms. Macrophages have classically been subdivided into M1 and M2, depending on their roles in immune response, wound healing, and promotion or inhibition of tumor growth. In human breast cancer, increased presence of M2 macrophages has been associated with poor prognosis. The authors hypothesized that rat mammary carcinomas have increased macrophage influx compared to benign mammary proliferative lesions and normal mammary glands as well. In humans, both M1 and M2 macrophages express CD68, while CD163 is expressed primarily by M2 macrophages. Based on a single immunolabeling protocol with anti-CD68 and anti-CD163 antibodies, the extent of macrophage influx was investigated by morphometry to quantitate the immunopositive cells in normal rat mammary glands, benign mammary proliferative lesions, and mammary carcinomas. In mammary carcinomas, there was significantly higher percentage of CD68+ cells compared to benign mammary proliferative lesions and normal mammary glands. There was also higher percentage of CD163+ cells in mammary carcinomas compared to benign mammary proliferative lesions. Thus, increase in CD68+ and CD163+ macrophages corresponded to increased malignancy of rat mammary tumors in this study.
Shock failure analysis of metallic structures by using strain energy density method
Authors: Çelik Mehmet , Mercimek Ümit , Kadıoğlu Suat
Published: May 2014

Failure of metallic structures operating under shock loading is a common occurrence in engineering applications. It is difficult to estimate the response of complicated systems analytically, due to structure’s dynamic characteristics and varying loadings. Therefore, experimental, numerical, or a combination of both methods is used for evaluations. In this study, test pieces made of two different materials are subjected to shock loads stemming from firing of a Gatling gun. Strain measurements are made, and finite element analysis of the test piece is performed. As a result of this study, strain energy density theory is applied to predict the shock failure of metallic structures.
Honoring Our Intellectual Ancestors
Authors: Beltrán Ramona , Mehrotra Gita
Published: May 2014

There are many unspoken norms in the culture of academia that are subtly communicated and integrated into academic socialization, from the doctoral training process into advanced professional development. The predominance of white, Western, masculine, heteronormative, and (post)positivist norms of academia historically and contemporarily can create challenges for women of color who engage in scholarship that reflects feminist and cultural values. In this article, we briefly explore the complexities affecting feminist of color scholars negotiating such values within the context of academia and particularly in navigating collaborative scholarship. We respond to these obstacles and complexities by providing a treaty of concrete strategies for creating allied, cooperative working relationships across diverse positionalities that honor these values.
Mechanical properties improvement of weldments using vibratory welding system
Authors: Rao P Govinda , Rao P Srinivasa , Krishna A Gopala
Published: May 2014

From the last few decades, vibratory welding techniques have been used for improving the mechanical properties of weldments. Previous results showed that welded test specimens under vibratory conditions exhibited improvements in mechanical properties than the conventional arc welding. In this present work, vibratory set-up has been developed for inducing mechanical vibrations during welding operation. The designed vibratory set-up produces the required frequency with amplitude and acceleration in terms of voltages. In the current investigation, weld specimens were prepared while varying the two input parameters: voltage and time of vibration. And the remaining process parameters such as travel speed, current, and other electrode parameters were kept constant. Metallurgical properties showed that refined microstructure has been achieved for the vibratory welded specimens. The refined grain structure is responsible for the improvement in flexural strength, ultimate tensile strength, impact strength, and hardness of the vibratory weld pieces.

Improved memetic algorithm for nonlinear identification of a three-dimensional elliptical vibration cutting system
Authors: Lu Mingming , Zhou Xiaoqin , Lin Jieqiong
Published: May 2014

This article focuses on the nonlinear Wiener system identification of three-dimensional elliptical vibration cutting. The developed three-dimensional elliptical vibration cutting device is actuated by four piezoelectric stacks, which have hysteresis nonlinear characteristics. Our research proposes an improved memetic algorithm in order to identify the nonlinear elliptical vibration cutting model. The improved memetic algorithm displays the advantages of both particle swarm optimization and genetic algorithm, while simultaneously overcoming these programs’ shortcomings. Moreover, it can quickly and efficiently search for the global optimization. The improved memetic algorithm’s identification performance may be compared with the conventional memetic algorithm, particle swarm optimization, and genetic algorithm using two well-known test functions. Test results demonstrate that the improved memetic algorithm can search the global optimal solution more efficiently than available state-of-the-art algorithms. Based on the input–output data collected from experiments, the accuracy of the identification model can potentially reach 97.55%. This relatively small margin of error verifies the efficiency of the proposed improved memetic algorithm for system identification.
Changes in Philippine labour relations policy: Convergence or divergence of productivity, flexibility and welfare?
Authors: Sale Jonathan P , Sale Arlene B
Published: May 2014

In the first decade of the present century, a succession of changes to Philippine labour law and jurisprudence sought to contribute to productivity and social welfare by introducing greater industrial relations flexibility, based on collective bargaining and voluntary dispute settlement. The article examines whether these changes actually resulted in any shift from a rights-based system for resolving industrial disputation to a system based on workplace-level interest-based negotiation, and whether they were accompanied either by higher labour productivity or by improved social welfare. The analysis draws on a conceptual framework that identifies coherent national labour regulation systems as being based on a convergence of three institutional approaches – to the operation of labour markets, of labour relations and of social security. Broadly, such labour regulation systems can be classified as either civil law or common law based. The Philippine labour regulation system is shown to have a hybrid basis, whose origins are briefly traced by identifying the legacy of the colonial and post-colonial phases, the martial law era and the restoration of democracy in 1986. Whereas Australia, another hybrid system, appears to have achieved some coherence in changes to the regulation of industrial relations, labour markets and social welfare, in the Philippines, such changes have not converged. In the 1990s, efforts to mitigate the traditional legalistic and adversarial character of industrial relations through liberalisation of restrictions on the right to organise were cross-cut by the effects of the growing labour market flexibility that resulted from integration into the global economy. Legal changes between 1999 and 2011 have not fostered voluntary self-organisation of distributive bargaining at enterprise level. Union membership, collective bargaining coverage and numbers of workers involved in notified or actual industrial action have declined, while reliance on compulsory arbitration and monetary compensation claims has remained high. Labour productivity has not improved. Within the context of globalisation, the labour market is increasingly characterised by numerical flexibility and a prevalence of small enterprises. High unemployment levels and a large informal sector indicate divergence between the systems for regulating labour and welfare.

Authors: AlJohani Khalid A. , Kendall Garth E. , Snider Paul D.
Published: May 2014

Purpose: To translate and examine the psychometric properties of the Arabic version of the Summary of Diabetes Self-Care Activities. Design: An instrument translation and validation study. Settings: A total of 243 participants (33 first sample and 210 second sample) diagnosed with type 2 diabetes mellitus were recruited from four primary health care centers in Saudi Arabia. Methods: The study was guided by the World Health Organization guidelines for translation and validation of instrument. Results: Translation indicators showed satisfactory outcomes for each included process in the forward-translation, an expert panel, and back-translation stages. Reliability and validity outcomes were as follows: test–retest, r = .912 and p < .001; split-half = .9; and Cronbach’s alpha (α) = .76. The alpha scores for the subscales were as follows: diet, .89; exercise, .83; blood glucose testing, .92; and foot care, .77. Principal component analysis revealed the presence of four components with eigenvalues greater than 1.0, explaining 34.4, 16.4, 15.4, and 11.2% of the variance in everyday practices for these items, respectively (accumulated = 77.1%). Conclusions: The translation and validation processes revealed acceptable psychometric properties. The instrument could evaluate diabetes self-care in Saudi Arabia and has the potential to be used in other Arabic-speaking populations.
Active flutter and aerothermal postbuckling control for nonlinear composite laminated panels in supersonic airflow
Authors: Song Zhi-Guang , Li Feng-Ming , Zhang Wei
Published: May 2014

In this article, active flutter and aerothermal postbuckling control of the nonlinear composite laminated panel with large deformation in supersonic airflow using the piezoelectric material are investigated. The distributed piezoelectric actuator and sensor pairs are bonded on the top and bottom surfaces of the laminated panel. The von Karman strain–displacement relation is used in the structural modeling. Unsteady aerodynamic pressure is evaluated by the supersonic piston theory. Hamilton’s principle and the assumed mode method are applied to formulate the equation of motion of the structural system. A discrete linear-quadratic-Gaussian controller is designed in this study to conduct the active flutter and postbuckling control. The proportional feedback control method is also applied in designing the controller. Time domain responses of the structural system are computed using the Runge–Kutta method. The control effects of the two control methods are compared. The influences of the placements of the piezoelectric actuator and sensor pairs on the control effects are also investigated. This study is helpful for the active aeroelastic design of the nonlinear structural system.

Published: May 2014

Understanding and facilitating new hires’ adjustment are critical to maximizing the effectiveness of recruitment and selection. The aim of the current study is to examine how organizational socialization tactics interact with perceived organizational support (POS) to influence socialization outcomes above and beyond proactive personality. Our sample consisted of 103 blue-collar apprentices from a well-established apprenticeship program that began in the Middle Ages in France. Using a time-lagged design, we surveyed apprentices in their first months of employment, while they were learning their trade (carpentry, roofing, and stone cutting). We found that POS significantly moderated the relationship between socialization tactics and three important socialization outcomes (learning the job, learning work-group norms, and role innovation), such that there was a positive relationship under low POS and a non-significant relationship under high POS. Unexpectedly, POS was negatively related to role innovation. Implications for the organizational socialization literature are discussed.
Colchicine for the Treatment of Acute and Recurrent Pericarditis
Authors: Norrid Sarah E. , Oliphant Carrie S.
Published: May 2014

Objective: To evaluate the literature with colchicine for the acute treatment of pericarditis and prevention of recurrent pericarditis. Data Sources: Searches of MEDLINE (1966-March 2014) and Cochrane Database (1993-March 2014) were conducted using the search terms pericarditis and colchicine. Limits were set for articles written in English with human subjects. Additional data were identified through bibliographic reviews. Study Selection and Data Extraction: Case series and clinical trials identified from the data sources were evaluated. Data Synthesis: A total of 16 case series and 5 prospective controlled trials were identified in the search. Early observational studies examined the use of colchicine, as an adjunct to aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), in patients with multiple cases of recurrent pericarditis. These studies showed decreased rates of recurrence after the initiation of colchicine therapy and formed the basis of the only available guidelines for the treatment of pericarditis. Since then, 5 randomized controlled trials have been published; 3 trials studied colchicine therapy for 6 months in patients with recurrent pericarditis, and the other 2 studied colchicine therapy for 3 months in patients with acute pericarditis. All 5 trials showed decreased rates of recurrence and symptom persistence, with similar rates of adverse events between study groups. Conclusions: Clinical controlled trials have shown that colchicine, as an adjunct to aspirin or NSAIDs, is effective in the prevention of recurrent pericarditis and in the management of acute symptoms. Colchicine was generally well tolerated with a low incidence of adverse events.

Authors: Sylvester Katelyn W. , Rocchio Megan A. , Belisle Caryn , Matta Lina , Goralnick Eric
Published: May 2014

Objective: Effective crisis response requires multidisciplinary communication and rapid action. Our goals are to highlight the experience of a pharmacy department’s response to the 2013 Boston Marathon bombing, to discuss the role of the pharmacist in a crisis response, and to identify potential learning opportunities for a future mass casualty event. Case Summary: Our initial response targeted 3 general areas: staffing, supplies, and communication. Pharmacist and technician staffing was increased throughout the hospital, with a 6-fold increase of pharmacists to the emergency department (ED). To ensure adequate supplies were available, inventory on the ED automatic dispensing cabinets (ADC) was assessed for vaccines, antibiotics, and vasoactive medications. ED pharmacists prepared emergent intravenous medications in the ED while the sterile products room bolstered our supply of intravenous medications for patients in the ED and operating room. Overall, there was a 33% increase in the number of ADC transactions, with pharmacists representing 28% of all ADC transactions. To optimize communication, we formulated a comprehensive plan for the timely dissemination of information to the entire pharmacy staff. Discussion: A mass casualty event is a rare occasion, and it is vital for the pharmacy department to respond rapidly with little notification. Conclusion: The role of a pharmacist is unique and can most effectively triage drug information and medication distribution, especially during times of high demand and high stress.
Changes in Platelet, Coagulation, and Fibrinolytic Activities in Mitral Stenosis After Percutaneous Mitral Valvotomy
Authors: Hasan-Ali Hosam , Mosad Eman
Published: May 2014

Markers of platelet activity (P-selectin), fibrinolysis (d-dimer), thrombin activity (prothrombin fragments 1, 2 [PF1,2] and thrombin–antithrombin III complex [TAT]), and inflammation (interleukin 1β [IL-1β]) were measured in 65 patients with mitral stenosis (MS) before and 2 weeks after percutaneous mitral valvotomy (PMV) and in 23 controls. All markers were significantly higher than the control and significantly decreased after PMV. P-selectin change correlated with the changes in left atrial diameter (LAD), pulmonary artery systolic pressure (PASP), and IL-1β. d-Dimer change had similar correlations, LAD, PASP, and IL-1β. The PF1,2 change correlated with the change in IL-1β. The TAT change correlated with the changes in LAD. The IL-1β change correlated with the changes in PASP. In conclusion, MS is associated with heightened inflammatory, platelet, thrombin, and fibrinolytic activities that decrease after PMV. Altered hemodynamics and reduced inflammatory activity might have a possible role in these changes.

Published: May 2014

To assess the impact of preanalytical variables of time and temperature on prothrombin time (PT), activated partial thromboplastin time (aPTT), dilute Russell viper venom time (DRVVT), activated protein C resistance (APCR), and d-dimer, samples from 23 healthy individuals and 18 patients having coagulopathy with known abnormal PT and aPTT were collected. Plasma from each individual was separately pooled and aliquoted; the first 2 aliquots were stored at room temperature then analyzed at 2 hours (baseline) and 4 hours postcollection. The remaining aliquots were stored at −20°C and thawed for analysis at 48 hours, 1, and 2 weeks. In both healthy participants and participants with coagulopathy, PT, aPTT, APCR, DRVVT, and D-dimer had no significant changes at 4 and 48 hours, and 1 and 2 weeks postcollection compared to baseline, or the changes were less than 10%. The results indicate PT, aPTT, DRVVT, APCR, and d-dimer can be stored for 2 weeks at −20°C without compromising clinical interpretation in both healthy individuals and individuals with coagulopathy. Increasing storage time will facilitate sample processing from off-site clinics.
Nonlinear numerical model with contact for Stockbridge vibration damper and experimental validation
Authors: Luo Xiaoyu , Wang Liang , Zhang Yisheng
Published: May 2014

The Stockbridge vibration damper is widely used in overhead transmission lines to reduce Aeolian vibration. Although a linear analytical model has been developed to interpret characteristics of the vibration damper, a much more detailed model is needed to investigate how the nonlinear factors of the structure affect its vibration characteristics. The paper presents a full-scale finite element model of the Stockbridge vibration damper, in which contact conditions are taken into account using the linear perturbation method. Relations between the contact conditions and mode frequencies were studied. It was proved that contact conditions between each two parts of the damper have significant influence on the stiffness of the whole structure. Results obtained from the numerical model compare well with those from the experiment. Finally, this numerical model was applied to investigate how the bonding material between the counterweight and steel strand cable affects the mode frequencies of the vibration damper.

Published: May 2014

Background:

The 2010 McDonald criteria allow diagnosing multiple sclerosis (MS) with one magnetic resonance imaging (MRI) scan. Nevertheless, not all patients at risk fulfil criteria at baseline. Other predictive factors (PFs) are: age ≤40 years, positive oligoclonal bands (OBs), and ≥3 periventricular lesions.

Objective:

The purpose of this study was to evaluate the 2010 McDonald criteria performance and to assess other PFs in patients without dissemination in space (DIS).

Methods:

Patients with clinically isolated syndrome (CIS) underwent baseline MRI and OB determination with clinical and radiological follow-up. Adjusted hazard ratios (aHRs) for clinically definite MS were estimated for DIS, dissemination in time (DIT), and DIS+DIT. Diagnostic properties at two years were calculated. In cases without DIS, combinations of ≥2 PFs were assessed.

Results:

A total of 652 patients were recruited; aHRs were 3.8 (2.5–5.8) for DIS, 4.2 (1.9–9.2) for DIT, and 8.6 (5.4–13.8) for DIS+DIT. Sensitivities were 69.6%, 42.3%, and 36.4%, and specificities were 67.3%, 87.9%, and 90.2%, respectively. In patients without DIS, aHRs varied between 2.7–5.5 and specificities ranged from 73.5–89.7% for PF combinations.

Conclusion:

The high specificity of the 2010 McDonald criteria is confirmed. In patients without DIS, PF combinations could be helpful in identifying those at risk for MS.

Published: May 2014

Background:

Risks of natalizumab (NAT) therapy have to be weighed against disease recurrence after stopping NAT.

Objectives:

The objective of this paper is to identify risk factors for recurrence of relapses after switching from NAT to fingolimod (FTY) in relapsing–remitting multiple sclerosis (RRMS).

Methods:

Patients ( n = 33) were treated with NAT for ≥1 year, and then switched to FTY within 24 weeks (mean follow-up on FTY 81.1 (SD 26.5) weeks). Annual relapse rates (ARR) and Expanded Disability Status Scale scores (EDSS) were assessed. Descriptive statistics, univariate logistic regression analysis, and receiver operating characteristic curves were conducted.

Results:

Overall, 20 patients (61%) had relapses after discontinuation of NAT and 16 (48%) during FTY therapy. The maximum incidence of relapses occurred between weeks 13–24 post-NAT. The last EDSS during the switching period predicted relapses during subsequent FTY therapy. EDSS >3 separated most powerfully between the groups (sensitivity 64%, specificity 88%) and significantly predicted relapses (relative risk 3.27, 95% CI: 1.5–7.3). Seventy-five percent of patients with EDSS ≤ 3 remained free of relapses, compared to 18% of patients with EDSS >3.

Conclusions:

There was an increase of the ARR in the first year after switching from NAT to FTY. Last EDSS during the switching period was a predictor of relapses during FTY.

Published: May 2014

Background:

Previous reports indicate an association between Epstein-Barr virus (EBV) antibody levels and multiple sclerosis (MS) disease activity, but the results have been conflicting.

Objectives:

The objective of this paper is to study if EBV antibody levels reflect MRI disease activity in MS and examine the potential for EBV antibody levels as biomarkers for treatment response.

Methods:

A total of 87 MS patients were followed for two years prior to and during interferon beta (IFNB) treatment, with MRI examinations and serum measurement of IgM and IgG antibodies to viral capsid antigen (VCA), EBV nuclear antigen 1 (EBNA-1) and early antigen (EA). Associations between EBV antibody levels and MRI activity were assessed by a logistic regression model.

Results:

Higher anti-EBNA-1 IgG levels were associated with increased MRI activity, OR = 2.95 (95% CI 1.07–8.10; p = 0.036) for combined unique activity (CUA; the sum of T1Gd+ lesions and new or enlarging T2 lesions). Although most patients were anti-VCA IgM negative, there was an inverse association, OR = 0.32 (95% CI 0.12–0.84; p = 0.021) with CUA during IFNB treatment.

Conclusions:

This study supports an association between anti-EBNA-1 IgG levels and MS disease activity. We also found an inverse association with anti-VCA IgM levels during IFNB treatment not previously described, indicating anti-VCA IgM as a possible biomarker for IFNB treatment response.
Retinal nerve fibre layer thickness correlates with brain white matter damage in multiple sclerosis: A combined optical coherence tomography and diffusion tensor imaging study

Published: May 2014

We investigated the association of retinal nerve fibre layer thickness (RNFL) with white matter damage assessed by diffusion tensor imaging (DTI). Forty-four MS patients and 30 healthy subjects underwent optical coherence tomography. DTI was analysed with a voxel-based whole brain and region-based analysis of optic radiation, corpus callosum and further white matter. Correlations between RNFL, fractional anisotropy (FA) and other DTI-based parameters were assessed in patients and controls. RNFL correlated with optic radiation FA, but also with corpus callosum and remaining white matter FA. Our findings demonstrate that RNFL changes indicate white matter damage exceeding the visual pathway.
