Leader humility and psychological empowerment: investigating contingencies
Authors: Jeung Chang-Wook , Yoon Hea Jun 
Published: September 2016

PurposeIn line with emerging conceptualizations of humility in organizations, the purpose of this paper is to examine how leader humility and distance-based factors (i.e. power distance orientation (PDO) and hierarchical distance) interact to predict follower psychological empowerment.Design/methodology/approachThe authors tested the hypotheses using a sample of 294 employees in South Korea. Moderated regression and bootstrapping analyses were conducted to test for direct and moderated relationships.FindingsResults indicated that leader humility positively predicted follower psychological empowerment, and followers’ PDO positively moderated this relationship. Results of a three-way interaction indicated that the impact of leader humility on follower psychological empowerment was strongest when both followers’ levels of PDO and hierarchical distance were high.Practical implicationsHumility can provide a new lens through which to understand the leadership process. Beyond anecdotal accounts, this study provided strong evidence for the value of humility on the list of qualities essential for successful leadership.Originality/valueThis is the first study to provide empirical evidence for the moderating effect of PDO and hierarchical distance on the relationship between leader humility and follower empowerment. The findings highlight the benefits of understanding the roles of followers’ cultural value orientation and hierarchical position in the effectiveness of leader humility.
Social media in Latin America: deepening or bridging gaps in protest participation?
Authors: Valenzuela Sebastián , Somma Nicolás M. , Scherman Andrés , Arriagada Arturo 
Published: September 2016

Purpose
The purpose of this paper is to explore the relationship between social media use and protest participation in Latin America. It advances two questions. First, does social media increase the chances of protest participation at the individual level, as prior research shows for advanced democracies? Second, in a region with glaring economic and political inequalities, does social media deepen or reduce the gaps in protest participation that exist among men and women, the young and the old, different social classes, or people with varying levels of political engagement?

Design/methodology/approach
The paper uses cross-sectional Latin American Public Opinion Project survey data from 2012 representing the adult population of 17 Latin American countries. It presents binary logistic regression models with protest participation as the dependent variable, social media use for political purposes as the main independent variable, control variables, and interactions.

Findings
Using social media for political purposes significantly increases protest chances – it is the second strongest predictor. Additionally, social media reduces protest gaps associated with individuals’ age, gender, psychological engagement with politics, and recruitment networks.

Originality/value
First, the paper shows that the contribution of social media to collective protest travels beyond advanced democracies – it also holds for more unequal regions with weaker democratic trajectories like Latin America. Second, it shows that social media may mitigate participatory inequalities not only, as shown by past research, regarding institutional participation (e.g. voting), but also regarding contentious tactics.
Internet freedom and social media effects: democracy and citizen attitudes in Latin America
Authors: Gainous Jason , Wagner Kevin , Gray Tricia 
Published: September 2016

Purpose
The purpose of this paper is to theorize the heightened exposure to information via the internet can lead citizens to be more critical about political conditions in their countries because using social media increases the likelihood of being exposed to dissident information. Further, the authors argue that the degree to which information is restricted, or internet access is limited, across countries can decrease this effect simply because the likelihood of exposure to a dissident flow is diminished.

Design/methodology/approach
The authors used survey data from the 2010 Latino Barometer to estimate a series of multilevel models to test whether citizens’ attitudes about the political conditions and about democracy in their respective countries worsen, and whether this effect is stronger in countries with higher internet freedom.

Findings
The results confirm that social media use has a negative influence on citizens’ attitudes about their national political conditions. In addition, respondents from those countries with more internet freedom tended to have more positive attitudes about their democracy and political conditions, generally. However, as a result of more internet freedom, the negative effects of internet and social media use on these attitudes was more pronounced in countries with more internet freedom.

Originality/value
These results suggest that the flow of information via the internet has substantial effect on how people feel about their government. This could be consequential for political stability, particularly in countries the conditions are not favorable. That said, these results also suggest that governments can actively decrease the odds of this dissidence building by controlling the flow of information.

BackgroundThe association between mortality risk and use of antidepressants in people with dementia is unknown.ObjectiveTo describe the use of antidepressants in people with different dementia diagnoses and to explore mortality risk associated with use of antidepressants 3 years before a dementia diagnosis.MethodsStudy population included 20 050 memory clinic patients from the Swedish Dementia Registry (SveDem) diagnosed with incident dementia. Data on antidepressants dispensed at the time of dementia diagnosis and during 3‐year period before dementia diagnosis were obtained from the Swedish Prescribed Drug Register. Cox regression models were used.ResultsDuring a median follow‐up of 2 years from dementia diagnosis, 25.8% of dementia patients died. A quarter (25.0%) of patients were on antidepressants at the time of dementia diagnosis, while 21.6% used antidepressants at some point during a 3‐year period before a dementia diagnosis. Use of antidepressant treatment for 3 consecutive years before a dementia diagnosis was associated with a lower mortality risk for all dementia disorders and in Alzheimer's disease.ConclusionAntidepressant treatment is common among patients with dementia. Use of antidepressants during prodromal stages may reduce mortality in dementia and specifically in Alzheimer's disease.
Short‐ and medium‐term effects of light to moderate alcohol intake on glycaemic control in diabetes mellitus: a systematic review and meta‐analysis of randomized trials

Published: September 2016

AbstractBackgroundPeople with diabetes are told that drinking alcohol may increase their risk of hypoglycaemia.AimsTo report the effects of alcohol consumption on glycaemic control in people with diabetes mellitus.MethodsMedline, EMBASE and the Cochrane Library databases were searched in 2015 to identify randomized trials that compared alcohol consumption with no alcohol use, reporting glycaemic control in people with diabetes. Data on blood glucose, HbA1c and numbers of hypoglycaemic episodes were pooled using random effects meta‐analysis.ResultsPooled data from nine short‐term studies showed no difference in blood glucose concentrations between those who drank alcohol in doses of 16–80 g (median 20 g, 2.5 units) compared with those who did not drink alcohol at 0.5, 2, 4 and 24 h after alcohol consumption. Pooled data from five medium‐term studies showed that there was no difference in blood glucose or HbA1c concentrations at the end of the study between those who drank 11–18 g alcohol/day (median 13 g/day, 1.5 units/day) for 4–104 weeks and those who did not. We found no evidence of a difference in number of hypoglycaemic episodes or in withdrawal rates between randomized groups.ConclusionsStudies to date have not provided evidence that drinking light to moderate amounts of alcohol, with or without a meal, affects any measure of glycaemic control in people with Type 2 diabetes. These results suggest that current advice that people with diabetes do not need to refrain from drinking moderate quantities of alcohol does not need to be changed; risks to those with Type 1 diabetes remain uncertain.
Sockeye salmon repatriation leads to population re‐establishment and rapid introgression with native kokanee
Authors: Veale Andrew J. , Russello Michael A. 
Published: September 2016

AbstractRe‐establishing salmonid populations to areas historically occupied has the substantial potential for conservation gains; however, such interventions also risk negatively impacting native resident stocks. Here, we assessed the success of the hatchery‐assisted reintroduction of anadromous sockeye salmon (Oncorhynchus nerka) into Skaha Lake, British Columbia, Canada, and evaluated the genetic consequences for native kokanee, a freshwater‐obligate ecotype, using single nucleotide polymorphism genotypic data collected from the reference samples of spawning Okanagan River sockeye and Skaha Lake kokanee presockeye reintroduction, along with annual trawl survey and angler‐caught samples obtained over an eight‐year period. Significant differentiation was detected between sockeye and kokanee reference samples, with >99% stock assignment. Low proportions of sockeye and hybrids were detected within 2008 and 2010 age‐0 trawl samples; however, by 2012, 28% were sockeye, rising to 41% in 2014. The number of hybrids detected rose proportionally with the increase in sockeye and exhibited an intermediate phenotype. Our results indicate that the reintroduction of anadromous sockeye to Skaha Lake is succeeding, with large numbers returning to spawn. However, hybridization with native kokanee is of concern due to the potential for demographic or genetic swamping, with ongoing genetic monitoring necessary to assess the long‐term effects of introgression and to support interactive fisheries management.

AbstractObjectivesOpioids are the preferred analgesic drugs to treat severe chronic pain conditions among dialysis patients; however, knowledge about their dialyzability features is limited. Oxycodone is increasingly used for the treatment of chronic pain conditions as oral controlled release (CR) tablets; however, evidence about this drug and its metabolites’ dialyzability is lacking.MethodsWe assessed, during 4‐hour dialysis sessions, the effect of standard hemodialysis (HD) and online hemodiafiltration (HDF) methods on the plasma concentration of oxycodone and its metabolites in n = 20 chronic pain patients with end‐stage renal disease who were stably treated with oral CR oxycodone. Chromatographic techniques were used to evaluate the studied compounds’ plasma concentrations at three different time points during dialysis.ResultsMean plasma concentrations of oxycodone and noroxycodone in the sample showed an overall reduction trend over time, but it was less enhanced for noroxycodone. Mean reduction in oxycodone and noroxycodone arterial concentrations was significant and higher with HDF (54% and 27%, respectively) than with HD (22% and 17%, respectively). Analysis of the regression of these compounds’ clearance on their increasing arterial concentration showed a more stable and linear clearance prediction with HDF (roughly 85 mL/min); with HD, for increasing arterial concentration, clearance of oxycodone decreased while noroxycodone clearance increased.DiscussionWhile no oxymorphone or noroxymorphone metabolites were detected, limited dialyzability of oxycodone and noroxycodone was documented along with insignificant postdialysis pain increment. This evidence will contribute toward considerations as to the safety of the use of oxycodone in dialysis patients in the future.
Population genomics identifies the origin and signatures of selection of Korean weedy rice
Authors: He Qiang , Kim Kyu‐Won , Park Yong‐Jin 
Published: September 2016

SummaryWeedy rice is the same biological species as cultivated rice (Oryza sativa); it is also a noxious weed infesting rice fields worldwide. Its formation and population‐selective or ‐adaptive signatures are poorly understood. In this study, we investigated the phylogenetics, population structure and signatures of selection of Korean weedy rice by determining the whole genomes of 30 weedy rice, 30 landrace rice and ten wild rice samples. The phylogenetic tree and results of ancestry inference study clearly showed that the genetic distance of Korean weedy rice was far from the wild rice and near with cultivated rice. Furthermore, 537 genes showed evidence of recent positive or divergent selection, consistent with some adaptive traits. This study indicates that Korean weedy rice originated from hybridization of modern indica/indica or japonica/japonica rather than wild rice. Moreover, weedy rice is not only a notorious weed in rice fields, but also contains many untapped valuable traits or haplotypes that may be a useful genetic resource for improving cultivated rice.

Authors: Peck Sarah , Corkrey Ross , Hamede Rodrigo , Jones Menna , Canfield Paul 
Published: September 2016

BackgroundDevil Facial Tumor Disease (DFTD) is an infectious tumor causing significant population declines in wild Tasmanian Devils. While clinical assessment and pathology have been well reported for DFTD, there is a lack of information on hematologic and biochemical alterations associated with DFTD.ObjectivesThe purpose of the study was to determine hematologic and serum biochemical variation in healthy, wounded, and DFTD‐affected Tasmanian Devils.MethodsBlood samples were collected from wild Tasmanian Devils at 5 sites in Tasmania. Hematology and clinical biochemistry variables were compared between clinically healthy, wounded, and DFTD‐affected devils. Differences were also analyzed among stages of DFTD, including individuals pre‐ and postclinical signs developing, and between ulcerated and nonulcerated DFTD tumors.ResultsStatistically significantly increased counts in WBC, neutrophils, and platelets, and concentration of fibrinogen, as well as decreased counts in lymphocytes, erythrocytes, and HGB concentration were observed in DFTD‐affected devils compared to healthy devils. Activities of ALP, ALT, and GLDH, concentrations of sodium, potassium and albumin, and sodium‐to‐potassium ratio and albumin‐to‐globulin ratio were significantly lower, and AST activity was significantly higher in animals with DFTD when compared to clinically healthy animals. No significant differences were found among stages of DFTD or ulcerated and nonulcerated tumors.ConclusionsThe differences in hematology and clinical chemistry variables in devils with DFTD compared to healthy devils are nonspecific and reflective of acute phase response and inflammation, and anemia of chronic disease. Similar changes are observed with wounds but to a lesser extent.
Desbordes contemporáneos: el cuerpo en ruinas del arte reciente
Authors: Fernández Bravo Álvaro 
Published: September 2016

<p>Este artículo propone una reflexión a partir de los artículos incluidos en este dossier sobre los desbordes temporales, estéticos y genéricos en la literatura y el arte contemporáneos. El ensayo se detiene en cuatro problemas derivados de convergencias identificadas entre los ensayos: el afuera, la carcasa, el marco y la supervivencia. Estos cuatro conceptos permiten elaborar una lectura de la contemporaneidad y preguntar si puede considerársela como una temporalidad distinta de la posmodernidad. </p>
Estados del arte. Puestas en escena de construcciones históricas e imaginarias durante el Bicentenario en Argentina
Authors: Usubiaga Viviana 
Published: September 2016

<p>El artículo propone problematizar los vínculos entre conocimiento histórico y ficción artística a partir del análisis de obras y acontecimientos artísticos contemporáneos basados en un capítulo fundante para la historia del arte argentino de fines de siglo XIX –el duelo intelectual y físico que mantuvieron Eduardo Schiaffino y Eugenio Auzón en 1891–; la proyección de ese episodio en la primera década del siglo XXI, más precisamente en el contexto del Bicentenario de la Revolución de Mayo, con la obra teatral <em>Apátrida. Doscientos años y unos meses</em> del dramaturgo Rafael Spregelburd; y otras producciones de artistas contemporáneos como Marcos López, Marcela Sinclair y Santiago Villanueva. Desde una multiplicidad de nuevas miradas sobre aquel episodio remoto se establece un recorrido entre documentos, textos, imágenes, performances y sonidos con el objetivo de reflexionar sobre los <em>estados del arte</em> durante las celebraciones del Bicentenario de la Nación Argentina. </p>
Una ficción propia Notas sobre el nacimiento de la ficción contemporánea a partir de Fundido a blanco, de Oscar Muñoz y La experiencia dramática, de Sergio Chejfec
Authors: Horne Luz 
Published: September 2016

<p>Este ensayo toma dos obras –<em> Fundido a blanco</em>, de Oscar Muñoz y <em>La experiencia dramática,</em> de Sergio Chejfec­– como un laboratorio para reflexionar sobre las transformaciones que sufre la categoría de ficción en el arte y la literatura contemporáneos. Basándome en ciertas formulaciones teóricas de Joan Fontcuberta, Jacques Rancière, Georges Didi-Huberman y del propio Sergio Chejfec sobre la relación entre la ficción y el documento, sugiero que en las obras de Muñoz y de Chejfec se despliega un modo singular de construcción ficcional subjetiva diferente al de la ficción clásica –basada en una lógica representativa– que puede ser entendido como simulación o como síntoma, y que se vincula con una lógica propia de lo digital. Si bien en estas obras se reflexiona sobre el ejercicio autobiográfico, en ellas se propone que la imagen y la palabra se despeguen de una temporalidad biográfica y cronológica para dar lugar a un recuerdo que sobrevive como un resto material, sensorial y afectivo. De este modo, se cancela la posibilidad de leer o mirar las obras en sus aspectos puramente testimoniales; o más bien se devela la trampa ficcional que allí se esconde. La urdimbre de la ficción, entonces, ya no se basa en una verosimilitud sino en la invención de un indicio o en la simulación de un documento.</p><p> </p>
Promesa y potencia. Notas sobre la crítica de la autonomía estética
Authors: Galende Federico 
Published: September 2016

<p>En este ensayo se revisa y problematiza el debate entre autonomía y pos-autonomía en el arte a la luz de un trazado sobre su génesis y diversos cuestionamientos actuales. En el contexto de este debate, el ensayo despliega a modo de sugerencia una serie de distinciones entre la experimentación y la vanguardia, mostrando hasta qué punto y en qué medida la autonomía de la esfera estética es una condición de la política entendida como exploración de los recursos que son propios de un modo de hacer como el del arte. </p>
Réplicas y reflejos en una crónica de Juan Villoro. Acerca de 8.8 El miedo en el espejo
Authors: Gárate Miriam V. 
Published: September 2016

<p>La “crónica en fragmentos” escrita por Juan Villoro luego del terremoto de Chile ocurrido en febrero de 2010, donde el azar (o el “destino”) lo encontró participando del Congreso Iberoamericano de Lengua y Literatura Infantil y-Juvenil, es pródiga en réplicas. Se replican allí (reverberan y se cuestionan) experiencias de orden personal y colectivo, de orden estético literario e histórico político. En ese contexto, algunos motivos cobran particular importancia: la figura paterna; las transformaciones del género cronístico operadas por ese “padre alternativo” llamado Carlos Monsiváis y sus reapropiaciones por parte de Villoro (en este caso en especial, de <em>No sin nosotros. Los días del terremoto 1985-2005</em>); la construcción de “autobiografía alterna” que posibilita actualizar momentos traumáticos de la historia chilena, pasados y presentes; la revisión de la propia escritura y del papel de los sismos en esa trayectoria. Examinar algunas de esas réplicas textuales es el propósito de este artículo. </p>
