Abstract
Background.  The factors that contribute to increasing obesity rates in human immunodeficiency virus (HIV)-positive persons and to body mass index (BMI) increase that typically occurs after starting antiretroviral therapy (ART) are incompletely characterized.
Methods.  We describe BMI trends in the entire Swiss HIV Cohort Study (SHCS) population and investigate the effects of demographics, HIV-related factors, and ART on BMI change in participants with data available before and 4 years after first starting ART.
Results.  In the SHCS, overweight/obesity prevalence increased from 13% in 1990 (n = 1641) to 38% in 2012 (n = 8150). In the participants starting ART (n = 1601), mean BMI increase was 0.92 kg/m2 per year (95% confidence interval, .83–1.0) during year 0–1 and 0.31 kg/m2 per year (0.29–0.34) during years 1–4. In multivariable analyses, annualized BMI change during year 0–1 was associated with older age (0.15 [0.06–0.24] kg/m2) and CD4 nadir &lt;199 cells/µL compared to nadir &gt;350 (P &lt; .001). Annualized BMI change during years 1–4 was associated with CD4 nadir &lt;100 cells/µL compared to nadir &gt;350 (P = .001) and black compared to white ethnicity (0.28 [0.16–0.37] kg/m2). Individual ART combinations differed little in their contribution to BMI change.
Conclusions.  Increasing obesity rates in the SHCS over time occurred at the same time as aging of the SHCS population, demographic changes, earlier ART start, and increasingly widespread ART coverage. Body mass index increase after ART start was typically biphasic, the BMI increase in year 0–1 being as large as the increase in years 1–4 combined. The effect of ART regimen on BMI change was limited.
Diversity in Phytochemical Composition and Antioxidant Capacity of Dent, Flint, and Specialty Corns

Published: June 2014

ABSTRACTDent, flint, and specialty genotypes of Indian yellow maize were evaluated for phytochemical content and their hydrophilic antioxidant capacity. Solid‐phase extraction coupled with solid–liquid extraction was used to obtain free phenolics and flavonoids from maize samples, reducing the use of excessive solvents and handling time. Bound phenolics were extracted with enhanced acidic hydrolysis to improve extractability. The phenolic contents in Indian maize genotypes ranged from 46 to 79 μmol of ferulic acid equivalents per gram of sample on a dry basis (db). Carotenoids in Indian maize genotypes were found to be equivalent to Chinese yellow maize and ranged from 13 to 24 μg/g of sample (db), whereas tocol content varied greatly in the range of 607–1,238 μg of α‐tocopherol equivalents/g of sample (db). Dent and flint corn did not exhibit differences (P > 0.05) in their phenolic contents, whereas among the specialty genotypes sweet corn contained the highest phenolics but least carotenoids (P < 0.05). Bound extracts appeared to contribute largely to 2,2′‐diphenyl‐1‐picrylhydrazyl free radical scavenging, hydrogen peroxide scavenging, and ferric reducing antioxidant power of maize genotypes. Sweet corn exhibited higher antioxidant capacity (P < 0.05) among all the genotypes. The antioxidant capacities correlated well with the total phenolic contents of the maize genotypes.

Published: June 2014

ABSTRACTA rapid shear‐based test (the GlutoPeak test, recently proposed by Brabender) was used to investigate gluten aggregation properties of durum wheat semolina and to relate them to pasta cooking behavior. Thirty semolina samples were characterized by means of the conventional approaches used for pasta‐quality prediction (protein content, gluten index, and alveographic indices). All samples were also analyzed by the GlutoPeak test, obtaining three parameters: maximum peak torque, maximum peak time, and area under the peak. The GlutoPeak indices were significantly correlated with protein content, gluten index, and W alveographic parameter. The cooking quality of pasta obtained from the 30 semolina samples was evaluated by sensory analysis in terms of stickiness, bulkiness, firmness, and overall quality. The GlutoPeak indices were significantly correlated with the sensorial parameters. In comparison with the alveographic test, which is presently the most used rheological approach for semolina characterization, GlutoPeak analysis presents some advantages represented by a smaller amount of sample (9 g), a shorter time (less than 5 min), and the possibility that untrained analysts can carry it out. In addition, following testing with larger sample numbers, the GlutoPeak test has the potential to be used instead of the gluten index as a rapid and reliable approach for medium‐quality semolina characterization.
First Report of Orobanche aegyptiaca on Kalanchoe blossfeldiana in Iran
Authors: Yousefi A. R. , Soheily F. 
Published: June 2014

The kalanchoe (Kalanchoe blossfeldiana) is an important ornamental species belonging to Crassulaceae. This plant is grown in commercial greenhouses. A survey revealed infections of broomrape, Orobanche aegyptiaca Pers. (syn. Phelipanche aegyptiaca Walp.), on kalanchoe plants in the province of Tehran (Pakdasht, 35°26′ N, 51°40′ E, 1,003 m elevation) in northern Iran in January 2014. About 1% of total Kalanchoe pots in a greenhouse were infected. The infection of kalanchoe was confirmed by verifying the attachment of the broomrape to the kalanchoe roots. Broomrape plant heights (from the soil surface) were between 13 and 28 cm, with flowering stems 5 to 14 cm. The stems were erect, unbranched, slender, 2 to 4 mm diameter, glandular-pubescent, pale yellowish, and inflorescent rather than lax. The leaves were reduced to bracts up to 3 to 6 mm long. There was one bract and two bracteoles surrounding each flower. The bracts measured 4 to 5 mm, had ovate lanceolates shorter than the calyces, and filiform, lanceolate bracteoles measured 5 mm. The calyces measured 4 to 6 mm, and were gamosepalous, hairy, and glandular. Corollas measured 22 to 28 mm, and were medium slate blue with darker veins, slightly curved, conspicuously infundibuliform, and glandular-pubescent. Stamens were epipetalous, inserted 5 mm above the corolla base, filaments (10 to 12 mm) hairy below, anthers were villous. Style (18 to 21 mm) and stigma lobes were light steel blue. Ovary measured 5 to 7 mm. O. aegyptiaca is the most important species of the broomrape, which parasitizes important crops, such as tomato, potato, tobacco, carrot, celery, mustard, and spinach, as well as some ornamental plants, such as chrysanthemum (1,2). In this survey, low infection did not lead to visible symptoms or damage to kalanchoe, but allowed seed production by the parasite. However, the parasite weed could pose a serious threat to production of this important ornamental plant at high infection. To our knowledge, this is the first report of O. aegyptiaca parasitism on kalanchoe in Iran. Additionally, to the best of our knowledge, this finding reports the first occurrence of a Crassulaceae plants as a host for O. aegyptiaca. References: (1) I. Ghannam et al. Am. J.

Copy number networks to guide combinatorial therapy for cancer and other disorders
Authors: Lin Andy , Smith Desmond J. 
Published: June 2014

ABSTRACTThe dwindling drug pipeline is driving increased interest in the use of genome datasets to inform drug treatment. In particular, networks based on transcript data and protein-protein interactions have been used to design therapies that employ drug combinations. But there has been less focus on employing human genetic interaction networks constructed from copy number alterations (CNAs). These networks can be charted with sensitivity and precision by seeking gene pairs that tend to be amplified and/or deleted in tandem, even when they are located at a distance on the genome. Our experience with radiation hybrid (RH) panels, a library of cell clones that have been used for genetic mapping, have shown this tool can pinpoint statistically significant patterns of co-inherited gene pairs. In fact, we were able to identify gene pairs specifically associated with the mechanism of cell survival at single gene resolution. The strategy of seeking correlated CNAs can also be used to map survival networks for cancer. Although the cancer networks have lower resolution, the RH network can be leveraged to provide single gene specificity in the tumor networks. In a survival network for glioblastoma possessing single gene resolution, we found that the epidermal growth factor receptor (EGFR) oncogene interacted with 46 genes. Of these genes, ten (22%) happened to be targets for existing drugs. Here, we briefly review the previous use of molecular networks to design novel therapies. We then highlight the potential of using correlated CNAs to guide combinatorial drug treatment in common medical conditions. We focus on therapeutic opportunities in cancer, but also offer examples from autoimmune disorders and atherosclerosis.
Conditional Auxin Response and Differential Cytokinin Profiles in Shoot Branching Mutants

Published: June 2014

AbstractStrigolactone (SL), auxin, and cytokinin (CK) are hormones that interact to regulate shoot branching. For example, several ramosus (rms) branching mutants in pea (Pisum sativum) have SL defects, perturbed xylem CK levels, and diminished responses to auxin in shoot decapitation assays. In contrast with the last of these characteristics, we discovered that buds on isolated nodes (explants) of rms plants instead respond normally to auxin. We hypothesized that the presence or absence of attached roots would result in transcriptional and hormonal differences in buds and subtending stem tissues, and might underlie the differential auxin response. However, decapitated plants and explants both showed similar up-regulation of CK biosynthesis genes, increased CK levels, and down-regulation of auxin transport genes. Moreover, auxin application counteracted these trends, regardless of the effectiveness of auxin at inhibiting bud growth. Multivariate analysis revealed that stem transcript and CK changes were largely associated with decapitation and/or root removal and auxin response, whereas bud transcript profiles related more to SL defects. CK clustering profiles were indicative of additional zeatin-type CKs in decapitated stems being supplied by roots and thus promoting bud growth in SL-deficient genotypes even in the presence of added auxin. This difference in CK content may explain why rms buds on explants respond better to auxin than those on decapitated plants. We further conclude that rapid changes in CK status in stems are auxin dependent but largely SL independent, suggesting a model in which auxin and CK are dominant regulators of decapitation-induced branching, whereas SLs are more important in intact plants.
Rhetoric and argument in social and environmental reporting: the Dirty Laundry case
Authors: M. Brennan Niamh , M. Merkl-Davies Doris 
Published: June 2014

Purpose– The purpose of this paper is to explore the interactive element in social and environmental reporting during a controversy between business organisations and a stakeholder over environmental performance.Design/methodology/approach– The paper adopts Aristotle's triangular framework of the rhetorical situation to examine how the writer, the audience, and the purpose of communication interact in the choice of rhetorical strategies used to persuade others of the validity and legitimacy of a claim during a public controversy. The analysis focuses on the strategies (i.e. moves and their rhetorical realisations) in the form oflogos(appealing to logic),ethos(appealing to authority), andpathos(appealing to emotion), with a particular emphasis on metaphor, used to achieve social and political goals. The authors base the analysis on a case study involving a conflict between Greenpeace and six organisations in the sportswear/fashion industry over wastewater discharge of hazardous chemicals. The conflict played out in a series of 20 press releases issued by the parties over a two-month period.Findings– All six firms interacting with Greenpeace in the form of press releases eventually conceded to Greenpeace's demand to eliminate hazardous chemicals from their supply chains. The paper attributes this to Greenpeace's ability to harness support from other key stakeholders and to use rhetoric effectively. Results show the extensive use of rhetoric by all parties.Originality/value– The authors regard legitimacy construction as reliant on communication and as being achieved by organisations participating in a dialogue with stakeholders. For this purpose, the paper develops an analytical framework which situates environmental reporting in a specific rhetorical situation and links rhetoric, argument, and metaphor.
Chinese aquatic farmers' participation in modern marketing channels
Authors: Geng Xianhui 
Published: June 2014

Purpose– The study uses survey data obtained in Jiangsu province, China, in June and August of 2012 to analyse the causal relations between aquatic farmers' relationship networks and trust, specific asset investments, joining in cooperatives and modern marketing channels participation.Design/methodology/approach– The authors used the structural equation mode to analyze the variables' causal relationships.Findings– The research results show that Chinese aquatic farmers' relationship networks can positively impact their participation in modern channels through the mediators of trust, specific assets investments and joining in cooperatives.Research limitations/implications– Two constructs are measured by a single item. Further study to incorporate multi-item constructs would be valuable.Practical implications– The policy implication is that the government should pay attention to farmers' relationship networks and can provide them with more public goods, especially channel and price information, to assist their evaluations and decision-making, which can help them to access modern marketing channels.Originality/value– The authors gave the answers that whether farmers' relationship networks affect their marketing channel selection decision and the function mechanism.
Career development and individuals with physical disabilities
Authors: Villanueva-Flores Mercedes , Valle-Cabrera Ramón , Bornay-Barrachina Mar 
Published: June 2014

Purpose– Few studies have focussed on the situation of employees with physical disabilities from the perspective of human resources management – in particular on the career development expectations of this group. The purpose of this paper is to meet this need by focussing on individuals with physical disabilities in Andalusia (Spain). It analyzes three key aspects: whether the perception of discrimination is related to the perception of inequity due to their disabilities, with this relationship being moderated by gender; whether these perceptions of inequality and discrimination lead to feelings of dissatisfaction with the employing organization; and whether the perception of discrimination mediates the relationship between perceived inequity and job dissatisfaction.Design/methodology/approach– Using the theoretical framework of organizational justice, regression analysis is applied to test the hypotheses in a population of 459 employed people with physical disabilities.Findings– The results show that perceived discrimination is due to perceived inequity when peers who do not have a disability are used as comparative reference; however, this relationship is not moderated by gender. These perceptions of inequity and discrimination cause individuals to feel dissatisfaction in organizations, and a mediating effect is found for the perception of discrimination in professional development opportunities. The control variables considered, age and education, are not significant in the relationships studied.Originality/value– An original and valued model is proposed to explain job dissatisfaction among employees with physical disabilities and the possibility of perceiving a dual disadvantage, in their possibilities for professional development. The model links together three variables that have not previously been linked all together in the literature – perceived inequity, perceived discrimination on the grounds of disability, and dissatisfaction – highlighting that perceived discrimination on the grounds of disability mediates the relationship between perceived inequity and dissatisfaction. This model can also examine whether a dual disadvantage is perceived owing to an individual's being a woman and having a disability, considering gender as a variable that moderates the relationship between perceived inequity and perceived discrimination on the grounds of disability.
Others service experiences: emotions, perceived justice, and behavior
Authors: Mattila Anna , Hanks Lydia , Wang Chenya 
Published: June 2014

Purpose– Often, service failures are witnessed by other customers, but little is known about how consumers react to service recovery aimed at other customers. Using the deontic theory of justice, this paper aims to examine consumers' reactions to justice directed toward other customers.Design/methodology/approach– Two studies were conducted to test the hypotheses. Both were 2 x 2 between subjects quasi experimental designs using written scenarios and surveys. The scenarios depicted an observing customer witnessing a service failure and recovery happening to another customer.Findings– Results show that the valence of the recovery attempt impacted the observing customer's reactions and evaluations, and that the observer's processing frame and loyalty status of the victim impacted the observing customer's judgments of fairness and behavioral intentions.Originality/value– These results provide guidance to service providers by shedding light on the impact of service failures and recovery on surrounding customers.
Pricing plans for a financial advisory service
Authors: Schlereth Christian 
Published: June 2014

Purpose
– In cooperation with a German online retail bank, the aim of this paper is to investigate how the bank should price a new fee-only financial advisory service. Two types of pricing plans differ in terms of their strategies for determining monthly prices: a fixed monthly price that is identical for all clients (i.e. a flat pricing plan) or a monthly price that varies as a function of each client's assets under management (i.e. a volume pricing plan).

Design/methodology/approach
– With a discrete choice experiment, this article studies client preferences for the two types of plans. To ensure that the respondents understood the financial consequences of their decisions, a price calculator was embedded into the discrete choice experiment to enable the respondents to determine their individual monthly prices based on their assets under management.

Findings
– Methodologically, the price calculator is useful for simplifying mathematically complex decisions, and it provides additional valuable information for analysis. Substantively, the results show that clients perceive both types of pricing plans as equally attractive; however, the service provider's revenues would increase by up to 12 per cent if it uses the volume pricing plan.

Originality/value
– This research extends the stream of literature on the measurement of pricing plan preferences and offers guidance for service industries, such as telecommunications, cloud computing services, insurances, or transportation. It extends the use of discrete choice experiments to study client preferences for different pricing plans and also integrates a decision aid, i.e. a price calculator, in the experiment to assist clients in comparing alternatives more effectively.
An empirical study on measurement of performance through TQM in Pakistani aviation manufacturing industry
Authors: Mahmood Khalid , Mahmood Ahmad Qureshi Ilyas , Nisar Asim 
Published: June 2014

Purpose
– Pakistani aviation industry is at the initial stage of its evolution and is undergoing transformation to a high-tech developed industry. However, the processes and practices in this industry are quite primitive and lack performance-measuring techniques for decision makers. The available literature in the total quality management (TQM) suggests a set of standardized factors for evaluating the performance of any organization. The purpose of this paper is to conduct a research with a view to judge the applicability of these TQM factors for measuring the performance of any aviation manufacturing organization in Pakistan.

Design/methodology/approach
– This research is focussed on performance evaluation of aviation manufacturing industry of Pakistan through TQM. Eight well-established dimensions of TQM frequently used by renowned researchers were used for an evaluation of the Pakistani Aviation Manufacturing Industry (PAMI), namely top management support, quality information availability, quality information usage, employee training, employee involvement, product/process design, supplier quality and customer orientation. An additional dimension of factual approach to decision making was also used based on the outcome of the pilot survey. Both qualitative and quantitative survey techniques were used for gathering the data for subsequent empirical analysis.

Findings
– The authors found that the suggested model of measuring organizational performance in PAMI was in general agreement with the TQM model of renowned researchers and can be useful tool for evaluation of quality profile of PAMI organizations.

Research limitations/implications
– During qualitative interviews with the top management, it was found that some of the PAM organizations did not have the complete data and information about their customers and markets, as well as company's human resource effectiveness, and supplier's performance. Although some of them had started maintaining it recently, but comprehensive longitudinal data were not available, which is quite useful for taking correct decisions.

Practical implications
– The outcome of this research is expected to contribute in the shape of a TQM measuring tool for decision makers in order to evaluate the performance of any aviation manufacturing organization of Pakistan. This model is, however, required to be empirically tested for its applicability in other regions as well for its generalization.

Originality/value
– This paper deals with the cross-sectional analysis study of the manufacturing organizations of the Pakistani aviation industry for application of TQM practices. It is an original work undertaken by the authors of this paper where various models have been studied and most commonly used dimensions have been utilized for testing the Pakistani aviation industry.
