Ohmic heating and space charge effects in microwave-plasma interaction
Authors: Niknam A. R. , Mirzaye T. , Khorashadizadeh S. M. 
Published: January 2015

AbstractThe nonlinear propagation of high power microwave beam in unmagnetized collisional plasma is studied taking into account the ponderomotive force, space charge and Ohmic heating effects. It is shown that the amplitude of electron temperature distribution is enhanced by increasing the microwave energy flux, and decreases when the microwave frequency increases. It is also demonstrated that the steepening of the electron density distribution increases when the amplitude of electron temperature profiles reduces and vice versa. Furthermore, by increasing the initial electron density, the amplitude and number of peaks are decreased, but the electron density distribution, the space charge field and the dielectric permittivity profiles are increased.

Published: January 2015

SUMMARYTwo global (re-)emerging zoonoses, leptospirosis and hantavirus infections, are clinically indistinguishable. Thirty-one patients, hospitalized in Sri Lanka for acute severe leptospirosis, were after exclusion of other potentially involved pathogens, prospectively screened with IgM ELISA for both pathogens. Of these, nine (29·0%) were positive for leptospirosis only, one (3·2%) for hantavirus only, seven (22·5%) for both pathogens concomitantly, whereas 13 (41·9%) remained negative for both. Moreover, in a retrospective study of 23 former patients, serologically confirmed for past leptospirosis, six (26·0%) were also positive in two different IgG ELISA hantavirus formats. Surprisingly, European Puumala hantavirus (PUUV) results were constantly higher, although statistically not significantly different, than Asian Hantaan virus (HTNV), suggesting an unexplained cross-reaction, since PUUV is considered absent throughout Asia. Moreover, RT–PCR on all hantavirus IgM ELISA positives was negative. Concomitant leptospirosis-hantavirus infections are probably heavily underestimated worldwide, compromising epidemiological data, therapeutical decisions, and clinical outcome.

AbstractMice have been a long-standing model for human biology and disease. Here we characterize, by RNA sequencing, the transcriptional profiles of a large and heterogeneous collection of mouse tissues, augmenting the mouse transcriptome with thousands of novel transcript candidates. Comparison with transcriptome profiles in human cell lines reveals substantial conservation of transcriptional programmes, and uncovers a distinct class of genes with levels of expression that have been constrained early in vertebrate evolution. This core set of genes captures a substantial fraction of the transcriptional output of mammalian cells, and participates in basic functional and structural housekeeping processes common to all cell types. Perturbation of these constrained genes is associated with significant phenotypes including embryonic lethality and cancer. Evolutionary constraint in gene expression levels is not reflected in the conservation of the genomic sequences, but is associated with conserved epigenetic marking, as well as with characteristic post-transcriptional regulatory programme, in which sub-cellular localization and alternative splicing play comparatively large roles.
Coalescence preference in densely packed microbubbles
Authors: Kim Yeseul , Lim Su Jin , Gim Bopil , Weon Byung Mook 
Published: January 2015

AbstractA bubble merged from two parent bubbles with different size tends to be placed closer to the larger parent. This phenomenon is known as the coalescence preference. Here we demonstrate that the coalescence preference can be blocked inside a densely packed cluster of bubbles. We utilized high-speed high-resolution X-ray microscopy to clearly visualize individual coalescence events inside densely packed microbubbles with a local packing fraction of ~40%. The surface energy release theory predicts an exponent of 5 in a relation between the relative coalescence position and the parent size ratio, whereas our observation for coalescence in densely packed microbubbles shows a different exponent of 2. We believe that this result would be important to understand the reality of coalescence dynamics in a variety of packing situations of soft matter.

Published: January 2015

Abstract
The histology of the reproductive tracts and their secretions are described. The functioning of various tracts in the elaboration and formation of the spermatophore is given, and the movement of sperm is traced through the male tract during spermatophore formation and through the female tract after copulation. The functions of the various reproductive secretions and the reproductive state of the moths during different reproductive periods are discussed.
Construction project leadership across the team development process
Authors: Senaratne Sepani , Samaraweera Aparna 
Published: January 2015

Purpose– The construction industry mostly adopts teams consisting of a collection of diverse professionals in each of its product delivery projects, where normally the construction project manager (CPM) becomes the leader of such a project team. The purpose of this paper is to identify the leadership roles of the CPM across the team development process.Design/methodology/approach– This was approached through a multiple case study research method carried out using three construction projects in Sri Lanka; two projects on traditional procurement method and another on design and build procurement method. Semi-structured interviews were conducted with the respective project managers and with other three distinct team members of each project.Findings– Based on the findings, leadership roles of the CPM across the team development process were revealed with the situational factors that affect these leadership roles in each stage of the team development process.Originality/value– Even though project leadership is discussed by pervious researchers, concrete evidence has not been provided to show how it should change at different stages of a project. This research addresses this gap and would guide CPMs to change their leadership role appropriately to suit the needs of each team development stage.
Food hygiene knowledge in adolescents and young adults
Authors: Mullan Barbara , Wong Cara , Todd Jemma , Davis Esther , Kothe Emily Jane 
Published: January 2015

Purpose
– The purpose of this paper is to utilise the comprehensive Food Safety Knowledge Instrument to compare food hygiene knowledge across a population of high school and university students in Australia and the UK.

Design/methodology/approach
– In total, 475 students from secondary schools and universities in Australia and the UK took part in a survey, which included a Food Safety Knowledge Instrument and demographic items.

Findings
– Food safety knowledge was generally very low. High school students had a mean score of only 38 per cent, while university students just reached a “pass” with a mean of 54 per cent. Demographics accounted for 41 per cent of variance in food knowledge scores. Female gender, being at university rather than high school, and living out of home rather than with parents were associated with greater food knowledge. Residing in Australia rather than the UK and being older were also associated with greater knowledge; however, these findings were subsumed by education group. Socio-economic status was not a significant predictor of food knowledge.

Practical implications
– Identifying demographic and cultural differences in food knowledge can help to identify at-risk populations to better target in theory and knowledge-based interventions.

Originality/value
– This study is the first to apply the knowledge instrument in an Australian population. Understanding the baseline knowledge in this population is an important first step at developing effective interventions for food safety.
Polish final purchasers’ expectations towards the features of dairy product packaging in the context of buying decisions
Authors: Baruk Agnieszka Izabela , Iwanicka Anna 
Published: January 2015

Purpose– The purpose of this paper is to identify and to make an in-depth analysis of importance of the environmental elements of dairy product packaging during consumer buying decisions process according to these elements’ compliance with consumer expectations.Design/methodology/approach– The paper is of theoretical and empirical character. In the theoretical part, the cognitive-and-critical analysis of the world’s literature on marketing and marketing management was applied. In the empirical part, such research methods were used as: questionnaire survey for gathering primary data and statistical analysis (including factor analysis and cluster analysis) for the analysis of the primary data and for the statistical reasoning, which made the basis for the final conclusions.Findings– On the basis of the research, it is possible to state that: environmental features of dairy product packaging are of great significance for the respondents, and meeting their expectations in this respect influences positively their buying decisions.Originality/value– The original contribution of the paper to theory is the identification of Polish purchasers’ expectations toward elements of dairy product packaging in the context of their buying decisions taken thanks to the fact that their expectations concerning the features of packaging are fulfilled. This knowledge makes it possible for offerers to manage efficiently and effectively dairy product packaging as a tool of influencing recipients, as well as to shape properly and use their marketing potential, which, in turn, determines the applicability value of the research and the conclusions drawn on the basis of the results.
Influence of shelf life labelling on the sensory acceptability of potato snacks
Authors: Samotyja Urszula 
Published: January 2015

Purpose
– The purpose of this paper is to assess how shelf-life labelling affects the sensory acceptability of potato snacks.

Design/methodology/approach
– The panel of assessors determined the key sensory attributes. Subsequently, affective sensory consumer testing was conducted. The samples of potato snacks with labels suggesting valid and false shelf life or without dating information were presented to 110 students. They rated the degree of colour intensity, oxidised flavour and crispness liking with the use of hedonic scale and accepted or rejected the sample. The testing was carried out in a sensory laboratory.

Findings
– Shelf-life labelling affects the overall acceptability of potato snacks, perception of crispness and oxidative flavour. These attributes were rated less favourably when the label suggested post-expiration. The influence of shelf-life labelling decreased with storage time period. Consumers are more willing to trust their own perception than labelling.

Practical implications
– The product may be rejected not only because of quality depletion when the shelf life is overestimated, but also as a result of denigration when the shelf life is underestimated.

Social implications
– Date legislation is necessary but it may be not sufficient without consumer education on food labelling and safety.

Originality/value
– Research on the influence of shelf-life labelling on the sensory acceptability of food is scarce. Understanding how consumers are affected by shelf-life information has important implications for both public policy as well as food manufacturers.

Authors: Quick Virginia , Corda Kirsten W. , Martin-Biggers Jennifer , Chamberlin Barbara , Schaffner Donald W , Byrd-Bredbenner Carol 
Published: January 2015

Purpose
– The purpose of this paper is to create a series of 30-60-second short videos to promote improved food safety behaviors of middle school youth, determine the feasibility of disseminating the videos through peer networks, and measure their effects on food safety attitudes, perceived social norms, and behaviors of youth.

Design/methodology/approach
– Food safety content specialists, learning experts, programmers, illustrators, project managers, instructional designers, scriptwriters, and stakeholders were involved in creation of the Don’t Be Gross short videos before evaluation by middle school youth (sixth to eighth grades). The experimental group (n=220) completed the following activities at about one-week intervals: pre-test, viewed videos, post-test, and follow-up test. The control group (n=112) completed the same activities at similar intervals but did not have access to the videos until after the follow-up test.

Findings
– Controlling for grade and gender, linear mixed-effects models revealed significant time by group effects for participants’ perceived susceptibility to foodborne illness; intentions to perform recommended food safety behaviors approached significance. Additionally, compared to the pre-test, the experimental group perceived their friends as being significantly more confident in performing food safety behaviors at post- and follow-up tests. Google Analytics data revealed that the bounce rate from the home page of the videos was low (38 percent) suggesting that the videos were engaging.

Originality/value
– The Don’t Be Gross videos were liked by youth and shared among their peers and may have the potential to promote positive food safety behaviors and intentions among youth.
Risk perception and propensity in bid/no-bid decision-making of construction projects
Authors: Chen Yong Qiang , Zhang Su Juan , Liu Li Sha , Hu Jia 
Published: January 2015

Purpose– Making the right bid/no-bid decision is critical to the success and development of construction contracting enterprises. Decision makers’ personal characteristics, such as risk perception and propensity, have great impact on bid/no-bid decisions, which is the major concern of this research. The purpose of this paper is to explore the relationship among decision makers’ risk perception, risk propensity, and their bid/no-bid decision making of construction projects, as well as the factors influencing the risk perception and propensity.Design/methodology/approach– In total, four hypotheses were proposed based on an extensive literature review. Experimental questionnaires were distributed to employees working in Chinese construction contracting enterprises with knowledge of construction bidding, and 134 valid questionnaires were obtained. Multivariate statistical analysis through SPSS 19.0 was used to analyze the acquired data.Findings– Data analysis shows that in the context of international construction contracting: risk perception has a negative influence on bid/no-bid decision making; while risk propensity produces a positive influence and the probability and magnitude of potential gain or loss both have significant impacts on risk perception, and the probability plays a more important role.Originality/value– This research studied the bid/no-bid decision making of construction projects from the new perspectives of risk perception and risk propensity of the decision makers.

Authors: Assis Edilson M. , Borges Ernesto P. , Vieira de Melo Silvio A.B. , Schnitman Leizer 
Published: January 2015

Purpose– The purpose of this paper is to compare four life data models, namely the exponential and the Weibull models, and their corresponding generalized versions,q-exponential andq-Weibull models, by means of one practical application.Design/methodology/approach– Application of the models to a practical example (a welding station), with estimation of parameters by the use of the least squares method, and the Akaike Information Criterion (AIC).Findings– The data of the example considered in this paper is divided into three regimes, decreasing, constant and increasing failure rate, and theq-Weibull model describes the bathtub curve displayed by the data with a single set of parameters.Practical implications– The simplicity and flexibility of theq-Weibull model may be very useful for practitioners of reliability analysis, and its benefits surpasses the inconvenience of the additional parameter, as AIC shows.Originality/value– Theq-Weibull model is compared in detail with other three models, through the analysis of one example that clearly exhibits a bathtub curve, and it is shown that it can describe the whole time range with a single set of parameters.
The development of innovations in organizations: the role of creative energy fields
Authors: Johannessen Jon-Arild , Skaalsvik Hugo 
Published: January 2015

Purpose– One problem that many organisations face today in the global economy is that too few ideas are turned into innovations. The purpose of this paper is to show how innovations in organisations may be obtained by means of creative energy fields.Design/methodology/approach– The design employed in the research represents a holistic, change oriented approach to innovation, and the methodology is conceptual where an analytical model is used.Findings– The paper provides arguments that organisations need to develop creative energy fields in order to enhance their innovative capacity and performance. In the paper the construct creative energy field is conceptualised as “a spot in an organisation where a Group of creative individuals collaborate and work together in order to bring to surface new ideas which may fuel innovation processes and Development in organisations”. The paper shows that creative energy fields are influenced by five distinct components; those of making a clear purpose, planning after the results have become apparant, an organisation’s rule breakers, drawing a map that changes the landscape, and igniting the flame of innovation. Furthermore, the findings encompass three conditions which need to be present in an organisation in order to make creative energy fields work.Research limitations/implications– The carried out focuses on the individual organisation which aims to enhance innovation performance.Practical implications– In relation to practical implications, the paper shows, in particular, how an organisation may move into areas of innovation by means of a Lego system of organising.Originality/value– To the authors’ knowledge, the creation and use of a novel construct, that of creative energy fields, represents newness and originality in innovation research at the level of the individual enterprise. Furthermore, the paper contributes to the extant management knowledge of innovation by showing how a Lego system of organising may foster innovation at the enterprise level.
Cystic trichoblastoma: A report of two cases with an immunohistochemical study
Authors: Misago Noriyuki , Inoue Takuya , Narisawa Yutaka 
Published: January 2015

AbstractWe herein report two cases of cystic trichoblastoma with an immunohistochemical study. The histopathological findings in these cases included new information, namely, their being composed of two and three cysts, the cystic components had features of a steatocystoma and a hybrid cyst in one case, and there were projections of an aggregation of trichoblastoma, as well as papillary projections of follicular germinative cells, from the cyst walls. The follicular germinative cells observed in the papillary projections and in the aggregations of trichoblastoma expressed cytokeratin‐15 (clone C8/144B) and PHLDA1, markers of follicular stem cells. Cystic trichoblastoma is a unique type of trichoblastoma, which originates from the cyst walls of an infundibular cyst (usually) or steatocystoma/hybrid cyst (rarely). In some cases, a trichoblastic infundibular cyst is considered to be a minor form (or possibly a primitive stage) of cystic trichoblastoma.

Published: January 2015

SummaryThe aim of the present study was to investigate if circulating adiponectin levels and the expression of AdipoR1 and AdipoR2 in peripheral blood mononuclear cells (PBMC) are altered in coronary artery disease (CAD) patients, with and without significant stenosis, compared to healthy patients. The present study included 69 patients with presenting symptoms of CAD (26 patients with significant stenosis and 43 patients without significant stenosis). The control group (CG) consisted of 33 healthy patients. Circulating adiponectin levels were measured by enzyme‐linked immunosorbent assay, whereas AdipoR1 and AdipoR2 mRNA levels in PBMC were determined by real‐time polymerase chain reaction. Adiponectin levels were significantly higher in patients with and without significant stenosis compared to the CG (P < 0.001 vs P = 0.006, respectively). Both patient groups had lower AdipoR1 levels compared to the CG (P < 0.001 vs P < 0.001, respectively). There were no significant differences in these parameters between the two patient groups. Adiponectin negatively correlated with body mass index, triglycerides, insulin and homeostasis model assessment of insulin resistance index (HOMA IR), and positively with high‐denisty lipoprotein cholesterol in the CG. Glucose, insulin, and the HOMA IR index negatively correlated with adiponectin in patients. A positive correlation between adiponectin receptors was found in patients and the CG. Decreased AdipoR1 mRNA levels and increased circulating adiponectin in advanced stages of CAD, as well as in patients without significant stenosis, compared to the CG, implies that CAD could be related to ‘adiponectin resistance’. Despite increased adiponectin, its protective effects could be diminished even in early stages of atherosclerosis.
A Silver‐Stain Modification of Standard Histological Slide Preparation for Use in Anthropology Analyses
Authors: Pinto Deborrah C. , Pace Eric D. 
Published: January 2015

AbstractThe traditional histology method typically employed by forensic anthropologists involves plastic embedding of undecalcified bone. The embedded sample is then cut by a diamond blade saw and ground to the required thickness of ~50–100 microns using a grinder. There are several limitations to this method: Cement lines may be blurred; depth‐of‐field artifacts may result from viewing thick sections; and medicolegal offices with limited budgets may not be able to invest in additional equipment or training for this method. A silver nitrate stain modification of the standard histology preparation technique of decalcified bone is presented. The benefits of this technique are that: Cement lines are viewed clearly; no depth‐of‐field artifacts are present; and because this is a modification of the standard technique used by histology laboratories typically employed by medicolegal offices, no additional equipment or training is required.
