Authors: Sio Terence T. , Liang Jackson J. , Chang Kenneth , Jayakrishnan Ritujith , Novotny Paul J. , Prasad Abhiram , Miller Robert C. 
Published: September 2014

Objectives:
To retrospectively evaluate outcomes among cancer survivors previously treated with thoracic radiotherapy (RT) who later underwent percutaneous coronary intervention (PCI).

Methods:
From 1998 to 2012, 76 patients first received curative RT (>30 Gy, except for Hodgkin lymphoma patients) involving the heart and lungs followed by PCI. Heart and lung–specific dosimetric parameters were correlated with overall survival (OS) and cardiac-specific survival by Cox variate methods.

Results:
The mean interval between cancer diagnosis and PCI was 3.7 years (range, 0.1 to 12.6 y). Median follow-up since cancer diagnosis was 5.5 years. At analysis, 46 patients (61%) were alive, 5 (7%) died of cardiac causes, and 9 (12%) of cancer. Higher maximum RT heart dose was related to poorer OS since PCI (P=0.009). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (P=0.005) and higher mean heart dose (P<0.001) were related to poorer OS since cancer diagnosis. β-Blockers, higher mean heart dose (hazard ratio [HR]=1.49, P<0.001), and percentage of targeted volume or organ receiving ≥40 Gy for heart doses (HR=1.32, P<0.001) were associated with poorer non–cancer-specific survival since cancer diagnosis. Diabetes (HR=3.84, P=0.008) and increased percentage of targeted volume or organ receiving ≥45 Gy (HR=1.01 per additional 100 cm3 irradiated, P=0.01) for the heart decreased major adverse cardiac event–free survival.

Conclusions:
Prior heart and lung–directed RT had volume-dependent and dose-dependent adverse effects on long-term cardiac outcomes for patients subsequently treated with PCI. RT planning that minimizes heart and lung irradiation doses should be encouraged.

AbstractAbscisic acid (ABA) is a well-studied regulator of stomatal movement. Hydrogen sulfide (H2S), a small signaling gas molecule involved in key physiological processes in mammals, has been recently reported as a new component of the ABA signaling network in stomatal guard cells. In Arabidopsis (Arabidopsis thaliana), H2S is enzymatically produced in the cytosol through the activity of l-cysteine desulfhydrase (DES1). In this work, we used DES1 knockout Arabidopsis mutant plants (des1) to study the participation of DES1 in the cross talk between H2S and nitric oxide (NO) in the ABA-dependent signaling network in guard cells. The results show that ABA did not close the stomata in isolated epidermal strips of des1 mutants, an effect that was restored by the application of exogenous H2S. Quantitative reverse transcription polymerase chain reaction analysis demonstrated that ABA induces DES1 expression in guard cell-enriched RNA extracts from wild-type Arabidopsis plants. Furthermore, stomata from isolated epidermal strips of Arabidopsis ABA receptor mutant pyrabactin-resistant1 (pyr1)/pyrabactin-like1 (pyl1)/pyl2/pyl4 close in response to exogenous H2S, suggesting that this gasotransmitter is acting downstream, although acting independently of the ABA receptor cannot be ruled out with this data. However, the Arabidopsis clade-A PROTEIN PHOSPHATASE2C mutant abscisic acid-insensitive1 (abi1-1) does not close the stomata when epidermal strips were treated with H2S, suggesting that H2S required a functional ABI1. Further studies to unravel the cross talk between H2S and NO indicate that (1) H2S promotes NO production, (2) DES1 is required for ABA-dependent NO production, and (3) NO is downstream of H2S in ABA-induced stomatal closure. Altogether, data indicate that DES1 is a unique component of ABA signaling in guard cells.

Authors: Ye Xin , Shao Chao , Zhang Zhijing , Gao Jun , Yu Yang 
Published: September 2014

Purpose
– The purpose of this paper is to design a microgripper that can achieve nondestructive gripping of a miniaturized ultra-thin-walled cylindrical part.

Design/methodology/approach
– The microgripper is mainly made of an inflatable silica gel gasbag, which can minimize the damage to the part in the gripping process. This paper introduces the design principle of a flexible air-filled microgripper, which is applied in an in-house microassembly system with coaxial alignment function. Its parameters and performance specifications have been obtained by simulation, experiment demarcating. The results show that the microgripper is able to grasp an ultra-thin-walled part non-destructively.

Findings
– For the microgripper, finite element simulations and experiments were carried out, and both results indicate that the microgripper can achieve nondestructive gripping of a miniaturized ultra-thin-walled cylindrical part, with good stability, great grasping force and high repeat positioning accuracy.

Originality/value
– Gripping the ultra-thin-walled part may lead to deformation and destruction easily. It has been a big bottleneck hindering successful assembly. This article introduces a novel microgripper using an inflatable sac. The work is interesting from an industrial point of view for a specific category of assembly applications. It provides a theoretical guidance and technical support to design a microgripper for a miniaturized ultra-thin-walled part of different sizes.
Does job position moderate the relationship between gender and ethics?: a cross-cultural analysis
Authors: Chen Chung-wen 
Published: September 2014

Purpose– The purpose of this paper is to examine the relationship between gender and ethics, the interaction of job position and gender on ethics, and the three-way interacting effects of cultural values, job position, and gender on ethics.Design/methodology/approach– The individual-level data were from the 2005-2008 wave of World Values Survey data set and the cultural values were from the GLOBE study. The research contained 26,639 subjects from 30 nations and used HLM to conduct data analysis.Findings– Results showed that men are more likely than women to justify ethically suspect behaviors. In addition, under high in-group collectivism, the ethical difference between genders tends to decrease at high job positions and under high performance orientation, the ethical difference between genders tends to increase at high job positions.Research limitations/implications– This research depends on secondary data; it is therefore impossible for the author to control the data collection process, which could be an issue for discussion. In addition, because of limited available studies to refer to, the formation of the individual-level moderator, job position, might cause some attention.Practical implications– Corporate education and training in regards to ethical issues becomes even more vital, especially for men, since the statistical results showed that men are more likely than women to be deviant. Meanwhile, organizations can help themselves by recruiting a greater number of females, as this study shows that females are seen to make more ethically sound decisions than males. Furthermore, under the contexts of high in-group collectivism and low performance orientation, both genders in higher job positions tend to be more unethical than people in lower positions. Since people in higher positions have the right and the power to set the ethical tone for the organization (Clinard, 1983; Posner and Schmidt, 1992), it becomes particularly essential for firms to pay close attention to ethical issues in higher job positions.Originality/value– The study proved that the relationship between gender and ethics is more complicated than expected; job position, and cultural values can jointly influence the individual-level relationship. In addition, since human behavior is complicated, employing multilevel method to investigate humane behaviors in the field of management becomes necessary in the future.
Deterministic mathematical morphology for CAD/CAM
Authors: Sarabia-Pérez Rubén , Jimeno-Morenilla Antonio , Molina-Carmona Rafael 
Published: September 2014

Purpose– The purpose of this paper is to present a new geometric model based on the mathematical morphology paradigm, specialized to provide determinism to the classic morphological operations. The determinism is needed to model dynamic processes that require an order of application, as is the case for designing and manufacturing objects in CAD/CAM environments.Design/methodology/approach– The basic trajectory-based operation is the basis of the proposed morphological specialization. This operation allows the definition of morphological operators that obtain sequentially ordered sets of points from the boundary of the target objects, inexistent determinism in the classical morphological paradigm. From this basic operation, the complete set of morphological operators is redefined, incorporating the concept of boundary and determinism: trajectory-based erosion and dilation, and other morphological filtering operations.Findings– This new morphological framework allows the definition of complex three-dimensional objects, providing arithmetical support to generating machining trajectories, one of the most complex problems currently occurring in CAD/CAM.Originality/value– The model proposes the integration of the processes of design and manufacture, so that it avoids the problems of accuracy and integrity that present other classic geometric models that divide these processes in two phases. Furthermore, the morphological operative is based on points sets, so the geometric data structures and the operations are intrinsically simple and efficient. Another important value that no excessive computational resources are needed, because only the points in the boundary are processed.
A comparative study on crack identification of structures from the changes in natural frequencies using GA and PSO
Authors: Mohan S.C. , Yadav Amit , Kumar Maiti Dipak , Maity Damodar 
Published: September 2014

Purpose
– The early detection of cracks, corrosion and structural failure in aging structures is one of the major challenges in the civil, mechanical and aircraft industries. Common inspection techniques are time consuming and hence can have strong economic implications due to downtime. The paper aims to discuss these issues.

Design/methodology/approach
– As a result, during the past decade a number of methodologies have been proposed for detecting crack in structure based on variations in the structure's dynamic characteristics. This work showcases the efficacy of particle swarm optimization (PSO) and genetic algorithm (GA) in damage assessment of structures.

Findings
– Efficiency of these tools has been tested on structures like beam, plane and space truss. The results show the effectiveness of PSO in crack identification and the possibility of implementing it in a real-time structural health monitoring system for aircraft and civil structures.

Originality/value
– The methodology presented establishes the PSO as robust and competent tool over GA for crack identification using changes in natural frequencies.
A computational investigation for propagation of elasto-viscoplastic zones in the shock loaded circular plates
Authors: Zajkani Asghar , Darvizeh Abolfazl , Darvizeh Mansour 
Published: September 2014

Purpose– The purpose of this paper is to introduce a computational time dependent modeling to investigate propagation of elastic-viscoplastic zones in the shock wave loaded circular plates.Design/methodology/approach– Constitutive equations are implemented incrementally by the Von-Kármán finite deflection system which is coupled with a mixed strain hardening rule and physical-base viscoplastic models. Time integrations of the equations are done by the return mapping technique through the cutting-plane algorithm. An integrated solution is established by pseudo-spectral collocation methodology. The Chebyshev basis functions are utilized to evaluate the coefficients of displacement fields. Temporal terms are discretized by the Houbolt marching method. Spatial linearizations are accomplished by the quadratic extrapolation technique.Findings– Results of the center point deflections, effective plastic strain and stress (dynamic flow stress) and temperature rise are compared for three features of the Von-Kármán system. Identifying time history of resultant stresses, propagations of the viscoplastic plastic zones are illustrated for two circumstances; with considering strain rate and hardening effects, and without them. Some of modeling and computation aspects are discussed, carefully. When the results are compared with experimental data of shock wave loadings and finite element simulations, good agreements between them are observed.Originality/value– This computational approach makes coupling the structural equations with the physical descriptions of the high rate deformation through step-by-step spectral solution of the constitutive equations.
Mentoring up-cycled: creating a community-based intervention for sexually abused adolescents
Authors: Williams Javonda , Nelson-Gardell Debra 
Published: September 2014

Purpose– The purpose of this paper is to detail a project that created a community-based mentoring intervention for sexually abused children and adolescents. The project features the use of family and community strengths, trauma sensitivity, current research and ecological theory to develop a curriculum for training mentors.Design/methodology/approach– This study used Community-Based Participatory Research (CBPR) methods to create a community-based intervention designed for sexually abused children and adolescents. This model supports the building and maintenance of the often fluid and relationship-driven processes that are characteristic of CBPR. The stages included: identification of research questions; assessment of community strengths, assets and challenges; defining priorities; developing research and data collection methodologies; collecting and analysing data; interpretation of findings; dissemination of findings; and applying findings to address action.Findings– The results include a recommendation to include community members in interventions for sexually abused adolescents.Research limitations/implications– The results of this study include recommendations for a culturally relevant training curriculum for mentors of sexually abused children and adolescents. Hallmarks of the resulting curriculum included using a hybrid of natural and programme mentors and inclusion of trauma sensitivity in training the mentors. The results from the pilot study are not generalisable since the pilot only included a small number of mentors and the effectiveness of the intervention was not tested. Further research is needed to determine the effectiveness of the intervention.Practical implications– The paper includes implications for further development of a mentoring curriculum for sexually abused children and adolescents. This curriculum promotes several potential benefits, including: incorporation of families and communities in discussion and awareness of sexual abuse and trauma sensitivity; and formal training for individuals who have the potential to remain important in the life of the child or adolescent long after formal services have ceased.Originality/value– The literature shows a lack of community level interventions for sexually abused children and adolescents. The focus of this project was to expand the traditional ecological context of mentoring from a micro or individual level intervention to a community level intervention.
Good idea, bad prerequisite, zero result – the meaning of context in implementing aftercare for young people in secure unit care
Authors: Andersson Vogel Maria , Sallnäs Marie , Lundström Tommy 
Published: September 2014

Purpose– The purpose of this paper is twofold: first, to report results from a quasi-experimental study of outcomes of a leaving care project for youth placed in secure unit care and second, based on the (zero) results, to analyse and discuss the interplay between organisational boundaries, social work and the target group when implementing a project such as the one studied.Design/methodology/approach– The outcome study had a quasi-experimental design. The young people in the leaving care programme were compared with a matched reference group who did not get the special leaving care services. Data were collected (structured Adolescent Drug Abuse Diagnosis-interviews) when the young people entered secure units and on follow-up (registered crime and re-entry into care).Findings– The outcome study showed that the leaving care project had no effect on the young people's situation at follow-up regarding re-offending and re-entry into secure unit care. This is understood and discussed in relation to the poor implementation of the leaving care project along with an inbuilt conflict between state and local municipality that overshadowed the good intentions of the project.Research limitations/implications– The effect study has a quasi-experimental design, and hence differences between the project group and the comparison group at T1 cannot be fully precluded, although nothing is pointing in such a direction. The unclear content of the intervention makes it difficult to decode how the variation in the support given to the young people eventually impacted the results. The zero-results apply to group level, but that may not be valid for each and every one in the project.Practical implications– According to earlier research, a key person following young persons through different phases of the care trajectory may be of importance. Learning from the CoC project, one can conclude that such a key person should preferably take the role of advocate for the young person, and not be an administrator mainly concerned with coordinating other professionals. Further, when planning and financing is split between organisations, that split hinders efforts to actually mobilise support for young people leaving secure unit care.Originality/value– Few leaving care services are designed for youth with severe behavioural problems and hence, the research is scarce. This study contributes with important knowledge about leaving care interventions for the target group.
MEDIA PROTECT – a programme targeting parents to prevent children's problematic use of screen media
Authors: Bleckmann Paula , Rehbein Florian , Seidel Michael , Mößle Thomas 
Published: September 2014

Purpose– The purpose of this paper is to describe theoretical background, concepts and materials for MEDIA PROTECT, a new elementary-school parent counselling programme to reduce problematic and, in the long term, addictive use of screen media via slowing the increase in screen equipment in children's bedrooms and promoting screen-free leisure activities. The aim of the pilot phase of MEDIA PROTECT was the implementation at a project school with a process evaluation by parents as well as teachers as a basis for improvements prior to a subsequent randomised controlled trial phase.Design/methodology/approach– At t1 and t2, questionnaires were handed out to all 220 families to record media use routines and media-related parenting styles. Advice on media education, information on media effects, plus hands-on technical support for installing protection software were offered to meet the support needs of different parental target groups recorded at t1 (pre-intervention). At t2, parents and teachers assessed MEDIA PROTECT regarding organisation, facilitators, content and duration/length.Findings– In the pilot phase, 60 per cent of families attended the 45-minute face-to-face input, for which high overall satisfaction (53 per cent ‘very high’, 45 per cent ‘high’) was reported. The written material was also rated ‘good’ (59 per cent) or ‘very good’ (33 per cent). Parents reported moderate positive changes in media-related parenting style. Teachers voted for the inclusion of a mandatory half-day teacher training session in the programme.Originality/value– The primary prevention of problematic media use is a neglected issue. This is despite the fact that ever younger age groups spend increasing portions of their time with screen media, which impairs physical, socio-emotional and cognitive development of children, especially those who are already vulnerable and disadvantaged.
Luxury brand commitment: a study of Chinese consumers
Authors: Li Ning , Robson Andrew , Coates Nigel 
Published: September 2014

Purpose
– The purpose of this paper is to assess brand commitment levels demonstrated by luxury brand consumers in China and seeks to identify the most significant combination of antecedents from brand affect, image, value and trust.

Design/methodology/approach
– A self-completion, researcher-supported questionnaire was disseminated within four Beijing shopping malls, generating 501 participants. The questionnaire comprised a range of scale sets covering brand affect, image, value, trust and commitment. The analysis comprised a summary overview of brand attainment followed by a substantive analysis involving confirmatory factor analysis and structural equations modelling to identify the most significant combination of antecedents relating to brand commitment.

Findings
– Regarding absolute consumer endorsement, brand affect was the most positive area, with image, trust and value representing relatively positive brand attributes. Declared commitment was relatively low, representing a potential commercial challenge. Value, represented by its social and symbolic components, and trust were identified as providing a significant and direct explanation of consumer commitment, represented by its affective and continuance dimensions. The role of value and trust must be central in marketing luxury brands given their direct and combined impact on consumer commitment.

Research limitations/implications
– The findings are transferable to other “Tier 1” locations in China, but take no account of either consumer behaviour outside of these wealthier conurbations, or segmentation of the associated markets.

Originality/value
– Geographic setting and consideration of a vast consumer group provides research value and contribution to marketing planning in the pursuit of higher levels of consumer commitment to their brands.
The impact of cultural sensitivity and information exchange on relationship quality
Authors: T.M. Nguyen Trang , Dinh Nguyen Tho 
Published: September 2014

Purpose
– The purpose of this paper is to investigate the mediating roles of cultural sensitivity and information exchange in the impact of market orientation on relationship quality.

Design/methodology/approach
– Using a survey data set collected from a systematic sample of 297 Vietnamese exporters, the authors tested a model that depicts the direct and indirect effects of market orientation on relationship quality.

Findings
– The authors found that market orientation has both direct and indirect effects, mediated by cultural sensitivity and information exchange, on relationship quality.

Research limitations/implications
– A major limitation of this study is the investigation only one side of the dyad, the exporter. Future research should use data collected from two sides of the dyad, the exporter and the importer.

Practical implications
– The results of this study suggest that, exporters, who want to maintain high quality relationships with importers, should adopt a market-oriented strategy to enhance the degree of cultural sensitization to as well as the level of exchange of information with their importers.

Originality/value
– This study enhances the understanding of predictors of relationship quality in export markets by confirming the mediating role of cultural sensitivity and information exchange in the impact of market orientation on relationship quality.
