Animaris Geneticus Parvus
Authors: Jansen Bo , L. Doubrovski Eugeni , C. Verlinden Jouke 
Published: July 2014

Purpose
– This paper investigates how designers exploit the full potential of additive manufacturing (AM). AM yields a broad range of advantageous properties including the possibility to fabricate mechanical multi-body structures.

Design/methodology/approach
– This case study explores the possibilities and limitations in designing mechanical multi-body structures for AM, focused on the development of a selective laser sintering (SLS) version of Theo Jansen’s “Strandbeest” walking mechanism, dubbed Animaris Geneticus Parvus (AGP). We discuss the design process and considerations involved and attempt to distill design guidelines.

Findings
– Novel structural solutions were developed to enable SLS fabrication of the AGP, specifically cross-shaped pivot pins, increased clearance between bodies, spacing studs, restricting axial play with pins, partial disassemblies and increased clearance around extremities. The result is a functioning walking mechanism of 74 components can be fabricated at once without human intervention.

Research limitations/implications
– This article represents a case study; although it does mention adapted design rules for SLS, its greatest contribution is the holistic approach – to integrate a number of engineering challenges in one prototypical manifestation.

Practical implications
– Part consolidation by AM could bring great benefits in future product design applications. The findings show that complex multi-body mechanical structures with more than 70 elements are feasible by AM without assembly. This presents new business opportunities for AM service bureaus and novel product opportunities for designers.

Originality/value
– As a case study, this article provides inspiration of the mechanical complexity beyond regular products – from original idea to end result. For researchers, key contribution is the approach in obtaining design optimization strategies which provides engineering designers with a new language to consider SLS.
Teaching metaliteracy: a new paradigm in action
Authors: Witek Donna , Grettano Teresa 
Published: July 2014

Purpose
– The purpose of this paper is to offer a model of information literacy instruction that utilizes social media to teach metaliteracy as the foundation for information literacy today and articulate the effects of social media on students’ information-seeking behaviors and processes and complete the goals articulated in part one of this study (Witek and Grettano, 2012).

Design/methodology/approach
– The study was conducted in conjunction with the course rhetoric and social media, co-designed and co-taught by the authors. Data sources consisted of student work and methodologies including textual and rhetorical analysis and observation. Findings are analyzed and presented through the lens of the Association of College and Research Libraries Standards (2000) and Mackey and Jacobson’s (2011) metaliteracy framework.

Findings
– The study identified four effects of social media use on students’ information literacy practices and behaviors: information now comes to users; information recall and attribution are now social; evaluation is now social; and information is now open. Data illustrate metaliteracy in practice and tie examples of this to the authors’ pedagogical decisions.

Research limitations/implications
– Article offers a model for teaching information literacy in the context of participatory information environments which can be adapted by other practitioners. Authors concede that the small sample size, limited by course enrollment, limits the generalizability of the study findings to student populations as a whole.

Originality/value
– Valuable to information literacy instructors and researchers because it offers the first formal application of concepts theorized in Mackey and Jacobson’s (2011) metaliteracy framework to information literacy instruction.
Framing sustainability performance of supply chains with multidimensional indicators
Authors: Varsei Mohsen , Soosay Claudine , Fahimnia Behnam , Sarkis Joseph 
Published: July 2014

Purpose– This paper aims to provide a framework which can assist focal companies in the development of sustainable supply chains. Sustainable development from an industrial perspective has extended beyond organisational boundaries to incorporate a supply chain approach.Design/methodology/approach– The literature related to sustainable supply chain management is reviewed by incorporating concepts from four organisational theories, including the resource-based, institutional, stakeholder and social network perspectives, to illustrate key drivers and enablers of sustainability initiatives in the supply chain. A conceptual multidimensional framework is then developed that can be used for the initial assessment of supply chain sustainability.Findings– Development and assessment of sustainability in supply chains are being increasingly incorporated as part of supply chain management today. This paper presents a multidimensional framework which can serve as a tool for research scholars and supply chain practitioners in identifying and assessing various economic, environmental and social performance indicators.Research limitations/implications– The framework and approach presented are conceptual, and require additional and broader validation. Additional theories, at differing levels, such as individual behaviour theory, should be utilised to further enhance and evaluate the framework. Developing and integrating analytical models for prescriptive and practical supply chain solutions can enhance the applicability of the framework.Practical implications– The framework adopts a multidimensional approach to assessing and designing sustainable supply chains, as it not only incorporates economic and environmental dimensions but also provides a practical approach to quantifying and embedding the social dimension into decision-making. The framework helps industry practitioners in initial exploration of trade-offs among economic, environmental and social performance of supply chains, which, in turn, could assist them in creating a business case for sustainability.Originality/value– The paper is one of few studies that incorporates some of the key aspects of all three dimensions of sustainability in a single overarching framework for supply chains and offers significant theoretical contribution and implications for sustainable supply chain management.
Motivations of social entrepreneurs
Authors: Aileen Boluk Karla , Mottiar Ziene 
Published: July 2014

Purpose– The aim of this study is to empirically investigate the additional motives, aside from the social interests that motivate social entrepreneurs. This paper does so by using an inductive approach and specifically carrying out a re-examination of two pieces of research examining social entrepreneurship that were carried out independently by the two researchers in South Africa and Ireland.Design/methodology/approach– The method used for the paper is content analysis. Research using qualitative content analysis focuses on the characteristics of language, talk and conversation (Sarantakos, 2005) with attention paid to the content or contextual meaning of the text. Thus, a qualitative content analysis is concerned with an examination of the uses of language. According to Downe-Wambolt (1992, p. 314), the aim of content analysis is “to provide knowledge and understanding of the phenomenon under study”.Findings– The findings indicate that the informants do have additional motivations with respect to their business ventures including lifestyle motives, receiving acknowledgement and generating profit.Originality/value– Few published papers investigate the motives of social entrepreneurs and explore if there are indeed any additional motivations aside from community interests. The results in this study identify that indeed social entrepreneurs are motivated by an array of motivations. The motivations we discovered in our research illustrate an individual who is mutually concerned with their communities, the environments in which they live in, lifestyle interests, acknowledgement and profit which may suggest that such community contributions could be sustained over time.

Authors: Yu Zhongliang , Zhao Yulong , Li Lili , Li Cun , Meng Xiawei , Tian Bian 
Published: July 2014

Purpose
– The purpose of this study is to develop a piezoresistive absolute micro-pressure sensor for altimetry. For this application, both high sensitivity and high overload resistance are required. To develop a piezoresistive absolute micro-pressure sensor for altimetry, both high sensitivity and high-overload resistance are required. The structure design and optimization are critical for achieving the purpose. Besides, the study of dynamic performances is important for providing a solution to improve the accuracy under vibration environments.

Design/methodology/approach
– An improved structure is studied through incorporating sensitive beams into the twin-island-diaphragm structure. Equations about surface stress and deflection of the sensor are established by multivariate fittings based on the ANSYS simulation results. Structure dimensions are determined by MATLAB optimization. The silicon bulk micromachining technology is utilized to fabricate the sensor prototype. The performances under both static and dynamic conditions are tested.

Findings
– Compared with flat diaphragm and twin-island-diaphragm structures, the sensor features a relatively high sensitivity with the capacity of suffering atmosphere due to the introduction of sensitive beams and the optimization method used.

Originality/value
– An improved sensor prototype is raised and optimized for achieving the high sensitivity and the capacity of suffering atmosphere simultaneously. A general optimization method is proposed based on the multivariate fitting results. To simplify the calculation, a method to linearize the nonlinear fitting and optimization problems is presented. Moreover, a differential readout scheme attempting to decrease the dynamic interference is designed.
A method for the tin pest presence testing in SnCu solder alloys
Authors: Skwarek Agata , Kulawik Jan , Czerwinski Andrzej , Pluska Mariusz , Witek Krzysztof 
Published: July 2014

Purpose
– The purpose of this study is to develop a testing method for tin pest in tin – copper (SnCu) alloys. Tin pest is the allotropic transformation of white β-tin (body-centered tetragonal structure) into gray α-tin (diamond cubic structure) at temperatures < 13.2°C.

Design/methodology/approach
– Bulk samples of Sn99Cu1 weight per cent (purity, 99.9 weight per cent) were cast in the form of roller-shaped ingots with a diameter of 1.0 cm and a height of 0.7 cm. The samples were then divided into four groups. The first group included samples artificially inoculated with α-tin powder. The second group was inoculated in the same way as the samples from the first group but additionally subjected to mechanical pressing. The third group of ingots was only subjected to mechanical pressing. The fourth group of samples consisted of as-received roller-shaped ingots.All samples were divided into two groups and kept either at −18°C or at −30°C for the low-temperature storage test. For tin pest identification, a visual inspection was made, using a Hirox digital microscope over 156 days at intervals not longer than 14 days. The plot of the transformation rate, presented as the average increase in the area of α-tin warts in time, was also determined. To demonstrate the differences between regions of β- and α-tin, scanning ion microscopy observations using the focused ion beam technique was performed.

Findings
– The first symptoms of tin pest were observed for the inoculated, mechanically pressed samples stored at −18°C, as well as those at −30°C, after less than 14 days. In the first stage of transformation, the rate was higher at −30°C for some time but, after about 75 days of storage at sub-zero temperatures, the rate at −30°C became lower compared to the rate at −18°C. Inoculation via the application of substances which are structurally similar to α-tin was efficient for the proposed new approach of rapid testing only when applied with simultaneous mechanical pressing. Infection from pressed-in seeds, leading to conventional seeded growth, was more rapid than infection in contact with seeds (without mechanical pressing), where the transition mechanism was induced by the epitaxial growth of metastable ice.

Originality/value
– The new rapid method for the diagnostic testing of the susceptibility of different SnCu alloys to tin pest in a period much shorter than 14 days (within single days for storage at −30°C) is proposed and described. The test procedure described in this paper produced results several times quicker than conventional procedures, which may take years. In effect, the behavior of tin alloys in the face of tin pest may be predicted much more easily and much earlier. The same procedure can be applied to other SnCu alloys used in electronics (and in other areas), if the test samples are prepared in a similar manner.

Authors: Soenen Bram , D’Oosterlinck Franky , Broekaert Eric 
Published: July 2014

Purpose
– The purpose of this paper is to investigate the prevalence of anxiety in youngsters with emotional and behavioral disorders, and its relation to other problems, using different informants.

Design/methodology/approach
– Data were collected in a Flemish treatment center. Educators completed a Child Behavior Checklist (CBCL) for each child, teachers completed a Teacher Report Form (TRF), and youth themselves completed a Youth Self Report (YSR) and a Screen for Child Anxiety Related Emotional Disorders (SCARED).

Findings
– Analyses indicated an explicit presence of anxiety. A clear relation was found between anxiety symptoms and internalizing problem behavior on the YSR, whereas only a slight relationship was found with the CBCL, and practically no relationship was found with the TRF. Only few correlations between anxiety and externalizing problems were found. Finally, youth themselves indicated strong correlations between anxiety and thought problems, whereas educators indicated strong correlations between youths’ anxiety and social problems.

Originality/value
– Several studies describe professionals’ difficulties to get a comprehensive perceptions of youths’ problems. This paper provides detailed insights in the nature of the informant discrepancies.

Published: July 2014

Purpose
– The purpose of this paper is to explore the effects of length of stay in an Oxford House (a sober living environment) with the number of days attended school/vocational training and days worked in the past 90 days with 292 women and 604 men.

Design/methodology/approach
– This paper presents quantitative data.

Findings
– Results indicated that number of days residing in these recovery homes was related to number of days attending school/vocational training and days worked.

Originality/value
– The present study suggested that in addition to staying abstinent from alcohol and drugs, Oxford House residents may improve gain useful life skills through vocational education, training, and employment. This is an area of further exploration for the substance abuse recovery community.
Thinking or acting: physical aggression in a therapeutic community: how best to manage it?
Authors: Ghazirad Marjan , Newrith Christopher 
Published: July 2014

Purpose
– The purpose of this paper is to provide an overview of a rare phenomenon of physical aggression in a Therapeutic Community (TC) and the clinical results of its management.

Design/methodology/approach
– The case vignette illustrates the psychodynamic and socio-therapy elements of the treatment model worked within the service prior to, during and after the incident. The information demonstrates how the TC model finds significant value in the living-learning experience that is possible in physical aggression and its management.

Findings
– The dynamic administration at the interface between TC with preparation groups has a potential pitfall which might increases the risk of aggression in TC.

Originality/value
– It is an original study focusing on the interface between new notion of preparation groups and TC following a case of Physical aggression. Physical aggression is a rare incident in TCs and there are very limited literature about it. The paper has a distinctive feature of being prepared in collaboration with TC service users.

Authors: Fell DB , Platt RW , Lanes A , Wilson K , Kaufman JS , Basso O , Buckeridge D 
Published: July 2014

BackgroundBefore 2012, few studies had addressed pregnancy outcomes following maternal influenza vaccination; however, the number of publications on this topic has increased recently.ObjectivesTo review comparative studies evaluating fetal death or preterm birth associated with influenza vaccination during pregnancy.Search strategyWe searched bibliographic databases from inception to April 2014.Selection criteriaExperimental or observational studies assessing the relationship between influenza vaccination during pregnancy and fetal death or preterm birth.Data collection and analysisTwo reviewers independently abstracted data from studies meeting the inclusion criteria.Main resultsWe included one randomised clinical trial and 26 observational studies. Meta‐analyses were not considered appropriate because of high clinical and statistical heterogeneity. Three studies of fetal death at any gestational age reported adjusted effect estimates in the range 0.56–0.79, and four of five studies of fetal death at <20 weeks reported adjusted estimates between 0.89 and 1.23, all with confidence intervals including 1.0. Adjusted effect estimates for four of five studies of fetal death at ≥20 weeks ranged from 0.44 to 0.77 (two with confidence intervals not crossing 1.0), whereas a fifth reported a non‐significant effect in the opposite direction. Among 19 studies of preterm birth, there was no strong evidence suggesting any increased risk, and meta‐regression did not explain the moderate between‐study heterogeneity (I2 = 57%).Authors' conclusionsMost studies reported no association between fetal death or preterm birth and influenza vaccination during pregnancy. Although several reported risk reductions, results may be biased by methodological shortcomings of observational studies of influenza vaccine effectiveness.
Comparison of acoustic and impedance methods with mask capnometry to assess respiration rate in obese patients recovering from general anaesthesia
Authors: Frasca D. , Geraud L. , Charriere J.‐M. , Debaene B. , Mimoz O. 
Published: July 2014

SummaryRespiratory depression, a potentially serious complication after general anaesthesia, can be detected promptly by close monitoring of both oxygen saturation and respiratory rate. Obese patients have morphological changes that may impair the reliability of monitoring devices. In this study, respiration rate was simultaneously recorded every second for up to 60 min using a computer in 30 adult obese patients (body mass index ≥ 35 kg.m−2), by three methods: acoustic; thoracic impedance; and capnometry via a facemask (Capnomask®, reference method). Of the 99 771 data triplets collected, only 85 520 (86%) were included; 12 021 (84%) were not studied due to failure of capnometry and 2240 (16%) due to failure of the acoustic method. Compared with capnometry, bias was similar using both the acoustic method and impedance (−0.3 bpm vs −0.6 bpm, respectively, p = 0.09), but limits of agreement were narrower for the acoustic method (±3.5 bpm vs ±5.3 bpm, respectively, p = 0.0008). The proportion of respiration rate values obtained with the acoustic method and impedance that differed by at least 10% or 20% for more than 15 s were 11% vs 23% and 2% vs 6%, respectively (p = 0.0009 for both comparisons). The acoustic sensor was well tolerated, while the facemask was pulled off on several occasions by four (13%) agitated patients. In obese patients requiring close monitoring of respiration rate, the acoustic method may be more precise than thoracic impedance and better tolerated than capnometry with a facemask.
Numerical Model of Dog Mast Cell Tumor Treated by Electrochemotherapy

Published: July 2014

AbstractElectrochemotherapy is a combination of high electric field and anticancer drugs. The treatment basis is electroporation or electropermeabilization of the cell membrane. Electroporation is a threshold phenomenon and, for efficient treatment, an adequate local distribution of electric field within the treated tissue is important. When this local electric field is not enough, there is a regrown tumor cell; however, if it is stronger than necessary, permanent damage to the tissue occurs. In the treatment of dogs, electrochemotherapy is not yet an established treatment for mast cell tumor in veterinary medicine, although there are studies showing evidence of its effectiveness. In this study, we examined electrochemotherapy of dog mast cell tumor with numerical simulation of local electric field distribution. The experimental result was used to validate the numerical models. The effect of tumor position and tissue thickness (tumor in different parts of dog body) was investigated using plate electrodes. Our results demonstrated that the electrochemotherapy is efficient and flexible, and even when the tumor extends into the subcutis, the treatment with plate electrode eliminated the tumor cells. This result suggests that electrochemotherapy is a suitable method to treat mast cell tumors in dog.

Published: July 2014

AbstractAimThe data on severe acetaminophen‐induced hepatotoxicity in children are very limited. This study explored the dose–response relationship between ingested acetaminophen and hepatotoxicity, the early biochemical and clinical predictors of hepatotoxicity, the impact of early N‐acetylcysteine treatment on hepatotoxicity and the incidence of nephrotoxicity.MethodsWe carried out a retrospective case study on 25 children aged 11–16 years with severe acetaminophen poisoning.ResultsInitial biochemical parameters predicted hepatotoxicity, defined as the maximum levels of the international normalised ratio (INR) and alanine aminotransferase (ALT). Significant relationships were found between: (1) the maximal INR and, for example, the initial bilirubin (p = 0.0003) and initial phosphate (p = 0.003), (2) the maximal ALT and, for example, the initial INR (p = 0.0003) and initial creatinine (p = 0.002), (3) the number of prehospital vomiting episodes and, for example, the maximal INR (p = 0.013) and maximum ALT (p = 0.0005) and (4) the time of N‐acetylcysteine initiation and, for example, maximum ALT (p = 0.001) and maximum gamma‐glutamyl transferase (GGT) (p = 0.007). The incidence of nephrotoxicity was 12%. There was no significant relationship between the amount of ingested acetaminophen and the degree of hepatotoxicity.ConclusionPaediatric patients at increased risk of severe hepatotoxicity were identified by early biochemical parameters, prehospital vomiting episodes and latency time before N‐acetylcysteine initiation.
