Authors: Karlsson Linn , Gerdle Björn , Takala Esa-Pekka , Andersson Gerhard , Larsson Britt 
Published: September 2016

Background: Exercise is often used in the treatment of chronic neck and shoulder muscle pain. It is likely that psychological aspects have an impact on the results of exercise-based treatments. Objectives: (1) To examine the associations between psychological factors and the effect of a home-based physical exercise intervention. (2) To examine differences in psychological factors at baseline between (a) subjects who continued in the trial and those who did not and (b) subjects who completed the intervention and those who did not. Method: A total of 57 women with chronic neck and shoulder pain were included in a home-based exercise intervention trial. Pain intensity, disability, and psychological factors (anxiety and depression symptoms, catastrophizing, fear-avoidance beliefs, self-efficacy, and pain acceptance) were measured at baseline, after 4–6 months, and after 1 year of exercise. Associations between the psychological factors and changes in pain intensity and disability were analysed, as well as differences in psychological factors at baseline between subjects who continued in and completed the intervention, and those who did not. Results: Associations between positive changes in pain intensity and disability were found for low fear-avoidance beliefs and low-pain self-efficacy at baseline. In addition, fear-avoidance beliefs at baseline were higher in the subjects who dropped out of the intervention than in those who continued. Pain acceptance at baseline was higher in the subjects who completed the intervention at the end of the trial. Conclusion: Particularly, fear-avoidance beliefs and pain self-efficacy should be taken into consideration when implementing home-based physical exercise as treatment for chronic neck pain. In addition, high pain acceptance might improve the adherence to prescribed exercise.

Published: September 2016

Background: In the United States, men who have sex with men (MSM) are known to disproportionately have HIV. The authors sought to describe the acceptability of providing at-home dried blood spot specimen collection kits for HIV testing among MSM. Methods: Between August 2010 and December 2010, the authors recruited Internet-using, HIV-negative or -unknown MSM to participate in a 12-month study of behavioral risks. Eligible participants were mailed an at-home HIV test. Results: Of the 896 men who were sent a test kit, 735 (82%) returned the kit. Returning a test kit was significantly associated with race ( P = .002), highest level of education ( P = .012), and annual income ( P = .026). The adjusted odds of black, non-Hispanic men returning a test kit were about half of the odds of white, non-Hispanic men returning a test kit (adjusted odds ratios: 0.49; 95% confidence intervals: 0.31-0.78). Conclusions: Men who have sex with men are willing to provide biological specimens as part of an Internet-based HIV prevention study.

Published: September 2016

BackgroundThe Wellbeing Plus Course is an internet-delivered psychological intervention for older adults with anxiety or depression.AimsTo compare the effectiveness of the Wellbeing Plus Course in a public health setting (clinic group) with its efficacy in a randomised controlled trial (research group).MethodParticipants (n = 949) were Australian adults aged 60 and above. Primary outcome measures were the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7).ResultsInitial symptom severity was higher in the clinic group and course completion was lower. Both groups showed significant symptom reductions at post-treatment and were satisfied with the treatment. Results were maintained at 3-month follow-up. Within-group symptom changes were comparable between settings; there were no between-group differences on primary outcomes or satisfaction.ConclusionsThe Wellbeing Plus Course is as effective and acceptable in routine clinical care, as it is in controlled research trials.

Published: September 2016

AbstractMolecular and crystal structures of dicationic tetrakis(1,3-benzodithiol-2-ylidene)cyclopentanone (1b), (1b2+)2(ReO4−)4(CH3CN)3(H2O)0.7, were successfully determined by X-ray single-crystal diffraction. It was suggested that two 1,3-dithiol-2-ylidenes adjacent to the carbonyl group were effectively conjugated with each other. The remaining two 1,3-dithiol-2-ylidenes, where two positive charges were mainly distributed, were considerably twisted from the central five-membered ring.
Spillover Effects in Seeded Word-of-Mouth Marketing Campaigns
Authors: Chae Inyoung , Stephen Andrew T. , Bart Yakov , Yao Dai 
Published: September 2016

Seeded marketing campaigns (SMCs) involve firms sending products to selected customers and encouraging them to spread word of mouth (WOM). Prior research has examined certain aspects of this increasingly popular form of marketing communication, such as seeding strategies and their efficacy. Building on prior research, this study investigates the effects of SMCs that extend beyond the generation of WOM for a campaign’s focal product by considering how seeding can affect WOM spillover effects at the brand and category levels. The authors introduce a framework of SMC-related spillover effects, and empirically estimate these with a unique data set covering 390 SMCs for products from 192 different cosmetics brands. Multiple spillover effects are found, suggesting that while SMCs can be used primarily to stimulate WOM for a focal product, marketers must also account for brand- and category-level WOM spillover effects. Specifically, seeding increases conversations about that product among nonseed consumers, and, interestingly, decreases WOM about other products from the same brand and about competitors’ products in the same category as the focal product. These findings indicate that marketers can use SMCs to focus online WOM on a particular product by drawing consumers away from talking about other related, but off-topic, products.

A Prematuridade na Perspectiva das mães: Estado Psicoemocional, Autoestima e Bonding em mães Primíparas e Multíparas
Authors: Alexandre Joana Dias , Monteiro Ligia , Branco Irina , Franco Carla 
Published: September 2016

A literatura tem referido que a prematuridade do bebé gera nas mães níveis mais elevados de ansiedade, sentimentos depressivos, assim como, níveis mais baixos de autoestima, comparativamente com mães de bebés de termo, o que poderá conduzir a um envolvimento emocional mais negativo com o recém-nascido. Essa vivência parece variar em função da paridade das mães (i.e., mãe pela primeira vez vs. multípara) não obstante não serem muito claras as particularidades desta variável. Este​ estudo teve como objetivo analisar num grupo de mães primíparas e multíparas com bebés prematuros, as associações entre o estado Psicoemocional, a Autoestima e o Bonding maternos. Participaram 50 mães (27 primíparas e 23 multíparas), com bebés pré-termo recrutados numa maternidade pública de Lisboa. Os resultados indicam que as mães multíparas apresentam níveis mais elevados de Sentimentos Depressivos expressando, também, uma maior Capacidade e Preparação Geral para a função materna. A Capacidade Geral para tratar do bebé surge associada de forma negativa com o seu estado Psicoemocional e de forma positiva com o Bonding. As associações negativas encontradas entre Ansiedade e Aceitação do bebé, e entre Estado Psicoemocional e Bonding não parecem variar em função da paridade, mostrando que os desafios se colocam a ambos os grupos de mães.
Performance analysis of variable speed multiphase induction motor with pole phase modulation
Authors: Liu Huijuan , Wang Jun , Zhang Zhenyang 
Published: September 2016

Abstract
The pole phase modulation (PPM) technique is an effective method to extend speed range and torque capabilities for an integrated starter and hybrid electric vehicles applications. In this paper, the five pole-phase combination types of a multiphase induction motor (IM) with 36 stator slots and 36 stator conductors are presented and compared quantitatively by using the time-stepping finite element method (TS-FEM). The 36 stator conductors of the proposed multiphase IM are fed by a 36 leg inverter and the current phase angle and amplitude of each stator conductor can be controlled independently. This paper focuses on the winding connection, the PPM technique and the performance comparative analysis of each pole-phase combination types of the proposed multiphase IM. The flux distribution, air-gap flux density, output torque, core losses and efficiency of five pole-phase combination types have been investigated.
Modeling and simulation of novel stepped DC coupled quasi Z-Multilevel Inverter for single phase systems
Authors: Meenakshi T. , Vanitha N. Suthanthira 
Published: September 2016

Abstract
This paper presents the modeling and simulation of a novel topology of quasi Z-Multilevel Inverter with stepped DC input. The proposed inverter incorporates a simple switching technique with reduced component count and is aimed at producing boosted multilevel output AC voltage. The inverter consists of two stages and the buck /boost operation is obtained by varying the shoot through period of the pulses obtained by maximum constant boost control with third harmonic injection. With all the advantages of the quasi Z-network, the proposed inverter eliminates the fly back diodes and capacitors present in a conventional Z-Multilevel Inverter. Further the stress on the devices is less which leads to reduction in component value and hence the cost. The novel stepped DC coupled Single Phase quasi Z-Multilevel Inverter is modeled and simulated in the MATLAB - SIMULINK environment and its performance is analyzed for varying input and switching conditions. The voltage and current waveforms across each stage of the inverter is analyzed and the results are presented for different levels of input.
Energy storage systems: power grid and energy market use cases
Authors: Komarnicki Przemysław 
Published: September 2016

Abstract
Current power grid and market development, characterized by large growth of distributed energy sources in recent years, especially in Europa, are according energy storage systems an increasingly larger field of implementation. Existing storage technologies, e.g. pumped-storage power plants, have to be upgraded and extended by new but not yet commercially viable technologies (e.g. batteries or adiabatic compressed air energy storage) that meet expected demands. Optimal sizing of storage systems and technically and economically optimal operating strategies are the major challenges to the integration of such systems in the future smart grid. This paper surveys firstly the literature on the latest niche applications. Then, potential new use case and operating scenarios for energy storage systems in smart grids, which have been field tested, are presented and discussed and subsequently assessed technically and economically.

Published: September 2016

Abstract
This study was carried out to evaluate the combined antimicrobial effect of thymol with lactic acid or sodium lactate on Salmonella and psychrophilic bacteria on chicken drumstick. Drumstick samples were artificially contaminated with Salmonella spp., then sprayed with sterile 0.85% NaCl solution (control), and thymol (0.25% w/v) with lactic acid (2% and 4% v/v) or sodium lactate (2% and 4% v/v), alone or in combination, for 30 s. The samples were stored at 4°C and analyzed on days 0, 2 and 4 for Salmonella and psychrophilic bacteria. Thymol alone did not show antibacterial effect on Salmonella and psychrophilic bacteria on chicken drumstick when compared with the control group during storage period. Spray with 4% lactic acid + thymol reduced Salmonella and psychrophilic bacteria by 1.4 and 1.8 log10 CFU/ml on day 0, respectively. A significant decrease in the number of Salmonella and psychrophilic bacteria was observed in the samples sprayed with 4% lactic acid and 4% lactic acid + thymol on days 2 and 4 when compared to the control (P<0.05). The combinations of thymol with lactic acid or sodium lactate did not show synergistic or additive effect on Salmonella and psychrophilic bacteria present on chicken drumstick with skin.

Authors: Adamski Marek , Kuźniacka Joanna , Banaszak Mirosław 
Published: September 2016

Abstract
The analysis of slaughter yield and meat quality was performed on a total number of 96 birds from four medium-heavy weight pedigree strains. Based on their strain, cockerels were divided into the following groups: group I - strain N88 (originating from New Hampshire), group II - strain R55 (Rhode Island Red), group III - strain S11 (Sussex) and group IV - strain P55 (Plymouth Rock). Each group consisted of 24 birds. At 12 weeks of age, half of the cockerels from each group was caponised. In total, 48 birds were caponised (12 birds in each strain). Based on the strain, capons were then divided into groups V (N88), VI (R55), VII (S11) and VIII (P55). It was noted that the strain and caponisation had influence on differences in such traits as the weight of eviscerated carcass with neck and slaughter yield. On the other hand, it was observed that caponisation did not affect significantly the total weight, percentage share of breast and drumstick muscles in carcasses of birds from analysed strains. No significant differences were observed between groups in terms of physicochemical properties of meat. The highest content of water in breast and drumstick muscles was observed among cockerels and capons from strain N88 (groups I and V). Protein content in cockerels’ breast muscles differed depending on their strain whilst among capons (groups V-VIII) it was similar. It was also noted that capons originating from strains S11 (VII) and P55 (VIII) stood out significantly with higher fat content in breast muscles compared to cockerels from the same strain (groups III and IV). The effect of caponisation on higher fat content in drumstick muscles was confirmed in all observed groups. Capons from all strains had more fat in drumstick muscles compared to cockerels of the same origin.
Eligibility of Lying Boxes at Different THI Levels in a Freestall Barn
Authors: Angrecka Sabina , Herbut Piotr 
Published: September 2016

Abstract
Cattle show a high sensitivity to changeability of microclimate conditions and heat stress that causes changes in the welfare and behaviour of cows. The presented study aimed at determining the relationship between the temperature humidity index (THI) value during the summer period and daily behaviour of dairy cows, including eligibility of lying boxes. All these aspects were measured under real production conditions. The investigated area, where microclimate conditions measurements were conducted, was a free-stall barn with single and double boxes, with manure and feeding alleys, housing 40 Holstein-Friesian cows. Observations were made on the behaviour of the cows based on a preference test concerning their choice of the best areas with respect to three ranges of THI values: neutral (N), warm (W) and hot (H). During the warm and hot period the research demonstrated a positive correlation between the level of THI and the share of standing cows (in period W - P<0.03 and H - P<0.008), and an inversely proportional one between the level of THI with participation of lying down cows (periods: W - P<0.06; H - P<0.004) and the length of their laying bouts in double boxes. The double boxes area was predominantly occupied, whereas single boxes area was the least often used. The occupation of manure alley areas was positively correlated with the level of THI.

Abstract
The uneven development of adipose tissues reflects a differential occurrence of biological events in vivo while the underlying molecular mechanism remains largely unknown. In the present study, the in vivo inflammatory status of an inbred obese porcine model, Lantang pig, was assessed, aiming to provide evidence for obesity biology. Compared with genetically lean pigs (crossbred, Duroc × Landrace × Large White), Lantang pigs exhibited a larger amount of ultra large adipocytes in subcutaneous adipose tissue accompanied with higher expression of macrophage/monocytes markers and pro-inflammatory genes (TLR4, CD14, CD11β, MCP1, TNFα, IL1β and IL6) and lower expression of cellular antioxidant enzymes (SOD1, 2 and 3). Plasma concentrations of LPS and TNF-α were also higher in Lantang pigs than in lean pigs. Among adipose tissues of Lantang pigs, the subcutaneous tissue had the most abundant expression of inflammation related genes (TLR4, CD14, TNFα and IL6) and the lowest level of cellular antioxidant genes (SOD 1 and 2), while the perirenal adipose tissue had opposite profile. Significant activation of p38 MAPK pathway was indicated by increased phosphorylation of p38 in the subcutaneous adipose tissue of Lantang pigs. Collectively, the bacteria-derived LPS induced inflammation-associated oxidative stress indeed exists in adipose tissues of Lantang pig, and the differential expressions of inflammatory and antioxidant genes, to some extent, account for the uneven development of the adipose tissue within bodies.
Alterations in intestinal and liver histomorphology and basal hematological and biochemical parameters in relation to different sources of dietary copper in adult rats
Authors: Tomaszewska Ewa , Dobrowolski Piotr , Kwiecień Małgorzata 
Published: September 2016

Abstract
Copper (Cu) is required for all basic biochemical and physiological processes. The aim of this study was to evaluate the effects of different sources of dietary Cu on the histomorphometry of liver and jejunal epithelium in adult rats. Male 12-week-old rats were used in a 12-week experiment. The control diet provided the required Cu level from sulfate, and other two diets were supplemented with Cu as a glycine complex at 75% and 100% of daily requirement. Basal hematological and plasma biochemical analyses were also performed. There was no effect of Cu supplementation on the liver weight and the plasma and liver Cu concentration. Histomorphometric analysis of liver tissue showed an increase in the collagen amount and intracellular space in the group supplemented with Cu amino acid. Cu given in the organic form at 100% of daily requirement decreased the muscular and submucosa layer and the crypt depth. In turn, organic copper given at 75% of daily requirement did not influence the intestinal morphology. Dietary Cu given to adult rats as copper sulfate or a glycine complex meeting 100% of the daily requirement appears to be less harmful with regard to intestinal epithelium than when given as a glycine complex at 100% of daily requirement.

Published: September 2016

AbstractA controlled interaction of materials with their surrounding biological environment is of great interest in many fields. Multifunctional coatings aim to provide simultaneous modulation of several biological signals. They can consist of various combinations of bioactive, and bioinert components as well as of reporter molecules to improve cell-material contacts, prevent infections or to analyze biochemical events on the surface. However, specific immobilization and particular assembly of various active molecules are challenging. Herein, an overview of multifunctional coatings for biomaterials is given, focusing on synthetic strategies and the biological benefits by displaying several motifs.

A Semiotic Analysis of Political Cartoons in Jordan in Light of the Arab Spring
Authors: Al-Momani Kawakib , Badarneh Muhammad A. , Migdadi Fathi 
Published: September 2016

AbstractThis paper provides a semiotic analysis of political cartoons published in Jordan prior to and during the 2013 elections. It seeks to depict the sociopolitical context after the 2011 Arab Spring and focuses on the changes to people’s practices and stances toward politics and politicians. The data consist of political cartoons by the Jordanian cartoonist Imad Hajjaj drawn during the parliamentary election campaigns in 2007, 2010, and 2013. This paper argues that the humor generated in cartoons conveys strong messages that require an analysis of the interaction between the different signs in cartoons and their social and ideological implications. A model of analysis derived from Barthes’ perception of denotation and connotation theories is adopted. This model is comprised of three types of messages: linguistic, literal, and symbolic. The analysis identifies different messages in the cartoons before and after 2011. Unlike the cartoons from 2007 and 2010, the linguistic and denoted messages in the cartoons of 2013 connoted a sense of salvation, achievement, victory, freedom, dignity, and democracy, merits that had rarely been highlighted in previous cartoons. This attitude is reflected by themes such as the positive image of the young, public awareness of political and national issues, and resistance towards corruption. The study sheds light on this neglected area of visual communication in the Arab world and hopes to provide new insights into the fields of semiotics, pragmatics, multimodal analysis, and critical discourse analysis.
