Authors: Keshavarz Yousef , Aziz Yuhanis Abdul , Jamshidi Dariyoush , Ansari Zeinab 
Published: April 2019

Purpose
The purpose of this paper is to follow a comparative framework to investigate the effects of outcome quality on loyalty through the mediating role of perceived value in four-star hotels and five-star hotels.

Design/methodology/approach
Following a review of the literature, some hypotheses were formulated to examine the effects of outcome quality on attitudinal loyalty and behavioral intention through the mediating role of perceived value. The data guiding the comparative analysis were collected from two groups of visitors staying either in four-start or five-star hotels. The sample included 356 international tourists who stayed overnight in four- or five-star hotels in Kuala Lumpur, Malaysia. Structural equation modeling was used to analyze the data.

Findings
Analyzing the data obtained helped to construct three models. In the first model, the effects of outcome quality on attitudinal loyalty and behavioral intention through the mediating role of perceived value in both group of customers was analyzed. In the second model, the effects of outcome quality on behavioral intention through the mediating role of perceived value were compared across the two groups. In the third model, all dimensions of attitudinal loyalty and behavioral intention were combined into one single variable called composite loyalty.

Originality/value
In the first model, the (in)direct effect of outcome quality on both of the dimensions of loyalty (attitudinal loyalty and behavioral intention) was confirmed through perceived value as the mediating variable. The results of processing the second model showed that the impact of outcome quality on behavioral intention was greater in the four-star hotels clients, whereas the effect of perceived value on behavioral intention was greater in the five-star hotels visitors. The third model revealed that the (in)direct effect of outcome quality on composite loyalty through perceived value was greater in the four-star hotels clients than that in the five-star hotels clients.
Financial centers and dividend policy: evidence from an emerging market
Authors: Farooq Omar , Aktaruzzaman Khondker 
Published: April 2019

Purpose
Is location in the financial center of a country significant determinant of a firm’s dividend policy? The purpose of this paper is to answer this question within the context of an emerging market.

Design/methodology/approach
The authors use variety of techniques (OLS regression, panel regression with random effects, TOBIT regression and quintile regression) to document the effect of location on dividend policies of Indian firms during the period between 2001 and 2016.

Findings
The results show significantly higher dividend payout ratios for firms headquartered in Mumbai, the main financial center of India. The results are robust for alternate proxy of dividend policy and for different sub-samples. The results also show that these results are more pronounced for firms with better information environment (firms with high analyst coverage).

Originality/value
To the best of the authors’ knowledge, most of the prior research overlooks how a location of firm’s headquarter in the financial center affects its dividend decisions. This paper fills this gap by documenting the relationship between the two in India.
We, the developing rete testis, efferent ducts, and Wolffian duct, all hereby agree that we need to connect
Authors: de Mello Santos T. , Hinton B. T. 
Published: April 2019

AbstractBackgroundThe mechanisms by which the rete testis joins the efferent ducts, which joins the Wolffian duct during development, are not known. Mouse and chick models have been helpful in identifying genes that are important for the development of each part, but genes have not been identified as to those that play a role in the joining of each part. Clinical implications of the failure of the male reproductive tract to form a fully functional conduit for spermatozoa are not trivial. Epididymal disjunction, the failure of the efferent ducts to join the testis, is one of several epididymal anomalies that have been observed in some boys who were cryptorchid at birth.ObjectiveA systematic review of studies focusing on the morphogenesis of the mesonephric duct and mesonephric tubules in different species, and identification of clinical issues should there be failure of these tissues to develop.DesignPubMed and GUDMAP databases, and review of books on kidney development were searched for studies reporting on the mechanisms of morphogenesis of the kidney and epididymis.Main outcomes measure(s)Gaps in our knowledge were identified, and hypotheses coupled with suggestions for future experiments were presented.ResultsA total of 64 papers were identified as relevant, of which 53 were original research articles and 11 were book chapters and reviews covering morphogenesis and clinical issues. Investigators utilized multiple species including, human, mouse, chick, Xenopus, bovine, and sheep.ConclusionFundamental understanding of the morphogenesis of the male reproductive tract is limited, especially the morphogenesis of the rete testis and efferent ducts. Therefore, it is not surprising that we do not understand how each part unites to form a whole. Only one mechanism of joining of one part of the tract to another was identified: the joining of the Wolffian duct to the cloaca via controlled apoptosis.
Does health coaching improve health‐related quality of life and reduce hospital admissions in people with chronic obstructive pulmonary disease? A systematic review and meta‐analysis
Authors: Long Hannah , Howells Kelly , Peters Sarah , Blakemore Amy 
Published: April 2019

PurposeTo systematically review the evidence for health coaching as an intervention to improve health‐related quality of life (HRQoL) and reduce hospital admissions in people with chronic obstructive pulmonary disease (COPD).MethodsWe systematically searched MEDLINE, EMBASE, PsycINFO, and CINAHL from database inception to August 2018 to identify all randomized controlled trials (RCTs) of health coaching for people with COPD. Eligible health coaching interventions had to include three components: goal setting, motivational interviewing, and COPD‐related health education. Data were extracted on study characteristics and the effects of the intervention on HRQoL, hospital admissions, physical activity, self‐care behaviour, and mood. Study quality was appraised by two authors using the Cochrane tool for assessing the risk of bias in RCTs. Effect sizes (standardized mean differences [SMD] or odds ratios [OR]) with 95% confidence intervals (CIs) were calculated and pooled using random effects meta‐analyses.ResultsOf 1578 articles, 10 RCTs were included. Meta‐analysis showed that health coaching has a significant positive effect on HRQoL (SMD = −0.69, 95% CI: −1.28, −0.09, p = .02, from k = 4) and leads to a significant reduction in COPD‐related hospital admissions (OR = 0.46, 95% CI: 0.31, 0.69, p = .0001, from k = 5), but not in all‐cause hospital admissions (OR = 0.70, 95% CI: 0.41–1.12, p = .20, from k = 3). Three of four studies reported significant improvements to self‐care behaviours such as medication adherence and exercise compliance.ConclusionsThis is the first systematic review to show that health coaching may be a candidate intervention to improve HRQoL and reduce costly hospital admissions in people with COPD.
Statement of contribution

What is already known on this subject?

COPD is a leading cause of death worldwide and considerably reduces HRQoL. In turn, HRQoL is associated with a range of adverse health outcomes in COPD.

Health coaching is a self‐management intervention for people with long‐term conditions such as COPD. Studies have examined whether health coaching improves HRQOL and other health outcomes in people with COPD, but no systematic review has been conducted.

What does this study add?

The first systematic review and meta‐analysis of RCTs of health coaching for people with COPD.

Health coaching may be a candidate intervention for improving HRQoL and reducing COPD‐related hospital admissions in people with COPD.

The need to establish the most effective health coaching components, delivery modality, and economic impact.
Environmental issues in Chilean salmon farming: a review
Authors: Quiñones Renato A. , Fuentes Marcelo , Montes Rodrigo M. , Soto Doris , León‐Muñoz Jorge 
Published: April 2019

AbstractThe growth of Chilean salmon production has not been free of important sanitary and environmental shortcomings. To ensure sustainability, it is necessary to understand the environmental impacts of salmon production on the Patagonian ecosystems. Currently, there is limited regulation or monitoring of impacts in the freshwater phase compared to the marine fattening stage, and there is some evidence of local eutrophication impact and diversity changes downstream the farms. Eutrophication of Patagonian channels and fjords from marine farms has been recognized as crucial environmental risk, although most scientific evidence comes from local effects below and around farms. So far, there are no regulations based on carrying capacity estimates to limit maximum fish biomass per area or water body. There is controversy regarding the potential role of nutrients derived from farming in triggering harmful algal blooms, yet current environmental monitoring and available information does not allow establishing or rejecting a cause–effect relationship. Pesticides used to control sea lice infestation have been shown to be deleterious to some non‐target species. There is evidence that the use of high quantities of antibiotics has allowed the development of antibiotic‐resistant bacteria in sediments and there is concern that salmon aquaculture has the potential to increase the proportion of antimicrobial‐resistant bacteria to antibiotics that are used in human medicine. There is an urgent need for more comprehensive ecosystem (beyond farm) studies on the impacts of antibiotics. Escapes of salmon (exotic species) from farms are a relevant environmental risk, although the most farmed species, Salmo salar, has shown little success in establishing wild populations. The review identifies critical knowledge gaps whose fulfilment is essential to advance towards an ecosystem approach to aquaculture and to protect Patagonian ecosystems.
Is Allocation Affected by the Perception of Others' Irresponsible Behavior and by Ambiguity?
Authors: Safra Zvi , Ma Sinong , Melkonyan Tigran 
Published: April 2019

AbstractThe article examines how the perception of others' irresponsible behavior and ambiguity regarding probabilities affect allocation among potential beneficiaries. To elicit these views, we conducted a survey where the participants were first asked to make an allocation of a fixed sum of money between a hereditary cancer, where chance plays a central role, and a lifestyle‐related cancer, where individual lifestyle decisions are more important. Our estimation results show that a substantial share of the respondents allocate significantly more to the hereditary cancer. This may indicate that these respondents care about others' irresponsible behavior. Then, we elicited perceptions of cancer hazards in the form of imprecise probabilities and examined the interplay between allocating behavior and risk perceptions. Finally, we investigated the effects of various socioeconomic characteristics, and of awareness of highly publicized cancer cases, on respondents' allocations.

AbstractWorldwide, there is a continuous need to develop alternative treatment methods to replace conventional processes for textile wastewater. In this regard, Fenton oxidation, with the potential of hydroxyl radical production, is an efficient method. Nevertheless, pH dependence, high chemical consumption and sludge production are a few aspects that limit its wide application. Therefore, to overcome these limits, integration of Fenton oxidation with other advanced oxidation processes is considered a viable option. Therefore, in this study, Ultrasonic‐assisted Fenton oxidation was investigated to observe the increase in degradation efficiency of Fenton oxidation. For this purpose, low frequency ultrasonic water bath was used and malachite green dye was used as a model pollutant. Central composite design was used for experimental design, and [OP]ini, OP:Fe+2(wt/wt), H2O2:Fe+2(wt/wt) and pH were used as control factors. Based on experimental results, maximum of 97.5% Chemical Oxidation Demand (COD) reduction was obtained at the process conditions of [OP]ini: 100 mg/L, OP:Fe+2: 50, H2O2:Fe+2: 1.5 and pH:3. Furthermore, 10 times reduction in the consumption of hydrogen peroxide was obtained. According to Pareto analysis, organic pollutant (OP) in interaction with OP is the most significant while pH was identified as the least. The process followed pseudo‐first order kinetics (k = 0.0196 min−1) with electrical energy order of 26.21 kWh/m3and the maximum energy consumption per COD removal of 0.8 kJ/COD, lower than those available in the literature. The results suggested that US‐assisted Fenton oxidation could be considered as an efficient method for treating the recalcitrant wastewater.

Published: April 2019

Purpose: Variables currently used in soccer training monitoring fail to represent the physiological demand of the player during movements like accelerations, decelerations, and directional changes performed at high intensity. We tested the hypothesis that respiratory frequency (fR) is a marker of physical effort during soccer-related high-intensity exercise. Methods: A total of 12 male soccer players performed a preliminary intermittent incremental test and 2 shuttle-run high-intensity interval training (HIIT) protocols, in separate visits. The 2 HIIT protocols consisted of 12 repetitions over 9 minutes and differed in the work-to-recovery ratio (15:30 vs 30:15 s). Work rate was self-paced by participants to achieve the longest possible total distance in each HIIT protocol. Results: Work-phase average metabolic power was higher (P < .001) in the 15:30-second protocol (31.7 [3.0] W·kg−1) compared with the 30:15-second protocol (22.8 [2.0] W·kg−1). Unlike heart rate and oxygen uptake, fR showed a fast response to the work–recovery alternation during both HIIT protocols, resembling changes in metabolic power even at supramaximal intensities. Large correlations (P < .001) were observed between fR and rating of perceived exertion during both 15:30-second (r = .87) and 30:15-second protocols (r = .85). Conclusions: Our findings suggest that fR is a good marker of physical effort during shuttle-run HIIT in soccer players. These findings have implications for monitoring training in soccer and other team sports.

Authors: Van Ramshorst Chad , Choi Woochol Joseph 
Published: April 2019

This study investigated the contact forces and muscle activation during 2 choreographed fall techniques in contemporary dancers and how these were affected by the fall technique. Ten collegiate-level dancers were instructed in 2 choreographed falls: (1) an anteriorly focused fall involving ankle plantar flexion, knee flexion, and hip flexion with dispersion of forces up the anterior surface of the shank (technique 1) and (2) a laterally focused fall involving inversion at the ankle with dispersion of forces up the lateral aspect of the shank (technique 2). The knee and hip contact forces were 26.3% smaller (technique 1: 1743 N vs technique 2: 1284 N) and 24.1% greater (technique 1: 1334 N vs technique 2: 1656 N), respectively, in technique 2 (P < .03). At the time of knee contact, percentage of maximal voluntary isometric contraction (%MVIC) was 45.8% greater for rectus femoris muscle (technique 1: 7.2% vs technique 2: 10.5%) and 96.9% greater for gluteus medius muscle (technique 1: 3.2% vs technique 2: 6.3%) (P < .01) in technique 2. The results provide insight into determining safer landing strategies to avoid knee injuries in individuals who experience a fall (ie, dancers, athletes, and older adults).

RationaleAssociations between urban (outdoor) airborne particulate matter (PM) exposure and TB and potential biological mechanisms are poorly explored.ObjectivesTo examine whether in vivo exposure to urban outdoor PM in Mexico City and in vitro exposure to urban outdoor PM2.5(< 2.5 µm median aerodynamic diameter) alters human host immune cell responses toMycobacterium tuberculosis.MethodsCellular toxicity (flow cytometry, proliferation assay (MTS assay)),M. tuberculosisand PM2.5phagocytosis (microscopy), cytokine-producing cells (Enzyme-linked immune absorbent spot (ELISPOT)), and signalling pathway markers (western blot) were examined in bronchoalveolar cells (BAC) and peripheral blood mononuclear cells (PBMC) from healthy, non-smoking, residents of Mexico City (n=35; 13 female, 22 male). In vivo-acquired PM burden in alveolar macrophages (AM) was measured by digital image analysis.Measurements and main resultsIn vitro exposure of AM to PM2.5did not affectM. tuberculosisphagocytosis. High in vivo-acquired AM PM burden reduced constitutive,M. tuberculosisand PM-induced interleukin-1β production in freshly isolated BAC but not in autologous PBMC while it reduced constitutive production of tumour necrosis factor-alpha in both BAC and PBMC. Further, PM burden was positively correlated with constitutive, PM,M. tuberculosisand purified protein derivative (PPD)-induced interferon gamma (IFN-γ) in BAC, and negatively correlated with PPD-induced IFN-γ in PBMC.ConclusionsInhalation exposure to urban air pollution PM impairs important components of the protective human lung and systemic immune response againstM. tuberculosis. PM load in AM is correlated with alteredM. tuberculosis-induced cytokine production in the lung and systemic compartments. Chronic PM exposure with high constitutive expression of proinflammatory cytokines results in relative cellular unresponsiveness.

The analytic expressions for the free energy, the concentration of equilibrium vacancies, the isothermal compressibility, the thermal expansion coefficient and the heat capacities at constant volume and at constant pressure of BCC substitutional alloy AB with interstitial atom C and with vacancy under pressure are derived by the statistical moment method. The theoretical results are applied to the thermal expansion coefficient of alloy FeCrSi in the interval of temperature from 700 K to 1100 K, in the interval of substitutional atom concentration from 0% to 10%, in the interval of interstitial atom concentration from 0% to 5% and in the interval of pressure from 0 GPa to 10 GPa. Our calculated results for main metal Fe are compared with the experimental data.
A geografia crítica e a economia política
Authors: Cruz Rita de Cássia Ariza da 
Published: April 2019

Como é amplamente sabido pelos geógrafos, estivemos e ainda estamos bem distantes de ter uma unidade na Geografia dada pelo movimento de renovação do pensamento geográfico ocorrido a partir dos anos 1970 e ao qual se chamou Geografia Radical, nos EUA, e Geografia Critica, na França, Alemanha e Brasil, entre outros. A despeito disso, este foi e é um dos movimentos mais importantes na história do pensamento geográfico. Isto posto, este artigo analisa esse movimento considerando sua relação com a economia política de orientação marxista, destacando o protagonismo de autores brasileiros (entre os quais diversos professores do Departamento de Geografia da FFLCH/USP) e estrangeiros que contribuíram para sua disseminação e consolidação, principalmente no Brasil. Um enfoque especial é dado à noção de desenvolvimento geográfico desigual.
The Mechanisms that Determine the Response of the Northern Hemisphere’s Stationary Waves to North American Ice Sheets
Authors: Roberts William H. G. , Li Camille , Valdes Paul J. 
Published: April 2019

Abstract
Stationary waves describe the persistent meanders in the west–east flow of the extratropical atmosphere. Here, changes in stationary waves caused by ice sheets over North America are examined and the underlying mechanisms are discussed. Three experiment sets are presented showing the stationary wave response to the albedo or topography of ice sheets, as well as the albedo and topography in combination, as the forcings evolve from 21 to 6 ka. It is found that although the wintertime stationary waves have the largest amplitude, changes due to an ice sheet are equally large in summer and winter. In summer, ice sheet albedo is the dominant cause of changes: topography alone gives an opposite response to realistic ice sheets including albedo and topography. In winter, over the Atlantic, stationary wave changes are due to the ice sheet topography; over the Pacific, they are due to the persistence of summertime changes, mediated by changes in the ocean circulation. It is found that the response of stationary waves over the last deglaciation echoes the above conclusions, with no evidence of abrupt shifts in atmospheric circulation. The response linearly weakens as the albedo and height decrease from 21 to 10 ka. As potential applications, the seasonal cycle over Greenland is shown to be sensitive primarily to changes in summer climate caused by the stationary waves; the annual mean circulation over the North Pacific is found to result from summertime, albedo-forced, stationary wave effects persisting throughout the year because of ocean dynamics.
