Evaluation of a clinical decision-making aid for nutrition advice in age-related macular degeneration
Authors: Stevens Rebekah , Bartlett Hannah , Cooke Richard
Published: August 2017

Age-related macular disease (AMD) is a multifactorial degenerative condition affecting the central area of the retina. Patients with AMD report that eye care practitioners are not giving consistent advice regarding nutrition and reported confusion as to what advice, if any, to follow. The aim of this study was to design and conduct a preliminary evaluation of a flowchart to support eye care practitioners in providing accurate, evidence-based nutritional advice to their patients. A flowchart was designed to take practitioners through a decision-making process that would determine whether a patient matched the Age-Related Eye Disease Study (AREDS) 2 eligibility criteria for supplementation. The flowchart was evaluated using a qualified and student optometrist cohort, with both cohorts completing confidence scales and students completing clinical scenarios. Qualified participants showed a significant increase in confidence scores from the initial survey ( M = 69.7%, standard deviation [ SD] = 16.2%) to the second survey after use of the flowchart for 2 weeks ( M = 82.1%, SD = 11.6%; t(45) = 7.33, p < .001; rs = .61, p < .001). The student participants also increased confidence scored after receiving the flowchart ( M of first survey = 41.7, SD = 14.6; M of second survey = 69.1, SD = 1.7; t(25) = 7.92, d = .81, p < .001) and increased the number of correct answers on five clinical scenarios. Overall, the flowchart has proved to be useful in boosting the self-efficacy of both qualified practitioners and student practitioners, as well as improving clinical decisions made by student practitioners.
Fake news and ideological polarization
Authors: Spohr Dominic
Published: August 2017

This article addresses questions of ideological polarization and the filter bubble in social media. It develops a theoretical analysis of ideological polarization on social media by considering a range of relevant factors. Over recent years, fake news and the effect of the social media filter bubble have become of increasing importance both in academic and general discourse. The article reviews the assumption that algorithmic curation and personalization systems place users in a filter bubble of content that decreases their likelihood of encountering ideologically cross-cutting news content. At the intersection of new media, politics and behavioural science, the article establishes a theoretical framework for further research and future actions by society, policymakers and industries.
Interpersonal Stress Generation—A Girl Problem? The Role of Depressive Symptoms, Dysfunctional Attitudes, and Gender in Early Adolescent Stress Generation
Authors: Meiser Susanne , Esser Günter
Published: August 2017

To provide further insight into stress generation patterns in boys and girls around puberty, this study investigated longitudinal reciprocal relations between depressive symptoms, dysfunctional attitudes, and stress generation, the process by which individuals contribute to the occurrence of stress in interpersonal contexts (e.g., problematic social interactions) or in noninterpersonal contexts (e.g., achievement problems). A community sample of N = 924 German children and early adolescents (51.8% male) completed depressive symptoms and dysfunctional attitudes measures at T1 and again 20 months later (T2). Stressful life events were reported at T2. Dysfunctional attitudes were unrelated to stress generation. Interpersonal, but not noninterpersonal, dependent stress partially mediated the relationship between initial and later depressive symptoms, with girls being more likely to generate interpersonal stress in response to depressive symptoms. Findings underscore the role of interpersonal stress generation in the early development of depressive symptomatology, and in the gender difference in depression prevalence emerging around puberty.
Contextualizing Informal Labeling Effect on Adolescent Recidivism in South Korea
Authors: Lee Jonathan
Published: August 2017

Symbolic interactionism argues that the effect of informal labeling by general others, such as family and friends, on behavior depends on the social context under which labeling takes place. Despite abundant research on informal labeling, little effort has been made to contextualize its impact on adolescent reoffending. Also, compared with other theories, only a few studies have been conducted among youths in Asian population. Using three consecutive waves of self-reported survey data from a nationally representative sample of 2,406 Korean adolescents, this study examined an interactional model for the informal labeling effect. Findings suggest that informal labeling, as well as school commitment and delinquent peer association, has an independent effect on delinquency. Also supported is the symbolic interactionist hypothesis that adolescents with greater involvement in delinquent subcultures were less susceptible to informal labeling. Implications of the findings are discussed.
Ethics and Issues of Secondary Prevention Efforts in Child Sexual Abuse
Authors: McCartan Kieran F. , Merdian Hannah L. , Perkins Derek E. , Kettleborough Danielle
Published: August 2017

This article discusses the ethical, practical, and moral issues surrounding secondary prevention efforts of child sexual abuse from a professional and practice-based perspective. Transcripts of a semistructured consultation event with n = 15 international experts on the secondary prevention of child sexual abuse were analysed using thematic qualitative analysis. The research identified four main critical areas linked to secondary prevention efforts, including, the psychology of self-reporting and disclosure; the interaction with and within existing legal, social, and professional frameworks; the scale and type of an appropriate response; and potential hurdles (i.e., within media, public, politics). The article outlines these areas, highlighting participant perspectives on risk-enhancing and mitigating factors for each domain.
Juvenile Corrections in the Era of Reform: A Meta-Synthesis of Qualitative Studies
Authors: Sankofa jub , Cox Alexandra , Fader Jamie J. , Inderbitzin Michelle , Abrams Laura S. , Nurse Anne M.
Published: August 2017

In this article, the authors synthesize knowledge from select qualitative studies examining rehabilitation-oriented juvenile residential corrections and aftercare programs. Using meta-synthesis methodology, the authors extracted and coded content from 10 research studies conducted by five authors across criminology, sociology, and social welfare disciplines. The total number of published works based on those studies analyzed was 18. Collectively, these studies offer insight into three major components of the juvenile correctional experience: therapeutic treatment and evidence-based practices, the shaping of identities and masculinities, and preparation for reentry. This analysis is particularly important as the United States is currently in an era of reform during which policymakers are increasingly espousing the benefits of rehabilitation for youth offenders over punishment. These studies took place before, during, and after this era of reform, and yet, the findings are surprisingly consistent over time, raising key questions about the effectiveness of the reform strategies.
Tired of Commuting? Relationships among Journeys to School, Sleep, and Exercise among American Teenagers
Authors: Voulgaris Carole Turley , Smart Michael J. , Taylor Brian D.
Published: August 2017

Public education policies that aim to improve educational outcomes can have the effect of increasing the distance that many students must travel to attend school. In this article, we use American Time Use Survey data to examine whether longer school commutes influence time spent on important health-promoting activities. We find school commute time to be strongly inversely related to time spent sleeping, and negatively related to time spent exercising for those with long commutes. Thus, increasing journey to school distances may have troubling public health implications for teens.
Peer Influence on IPV by Young Adult Males: Investigating the Case for a Social Norms Approach
Authors: McKool Marissa , Stephenson Rob , Winskell Kate , Teten Tharp Andra , Parrott Dominic
Published: August 2017

Nearly 32% of women report experiencing physical violence from an intimate partner and more than 8% report being raped by a significant other in their lifetime. Young people’s perceptions that their peers perpetrate relationship violence have been shown to increase the odds of self-reported perpetration. Yet, limited research has been conducted on this relationship as individuals begin to age out of adolescence. The present study sought to examine the link between the perception of peer perpetration of intimate partner violence (IPV) and self-reported IPV perpetration among a sample of predominately young adult (21-35 years) males. This study also explored the discordance between the perception of peer IPV behavior and self-reported perpetration. Data from 101 male peer dyads ( n = 202) were taken from a study on the effects of alcohol and bystander intervention in Atlanta, Georgia. Thirty-six percent ( n = 73) of men reported perpetrating physical IPV and 67% ( n = 135) reported perpetrating sexual IPV in the past 12 months. Nearly 35% ( n = 55) of the sample reported that none of their peers had perpetrated physical IPV, which contradicted their friend’s self-report of physical IPV perpetration. Similarly, 68% ( n = 115) of the men perceived none of their peers to have perpetrated sexual IPV, which contradicted their friend’s self-report of sexual IPV perpetration. Discordance variables were significantly associated with self-reported perpetration for both physical (χ2 = 152.7, p < .01) and sexual (χ2 = 164.4, p < .01) IPV. These results point to an underestimation of peer IPV perpetration among young adult males. Findings suggest a traditional social norms approach to IPV prevention, which seeks to persuade individuals that negative behaviors are less common than perceived, may not be the best approach given a significant number of men believed their friends were nonviolent when they had perpetrated violence.
Anticoagulation of Percutaneous Ventricular Assist Device Using Argatroban-Based Purge Solution: A Case Series
Authors: Blum Emily C. , Martz Carolyn R. , Selektor Yelena , Nemeh Hassan , Smith Zachary R. , To Long
Published: August 2017

Impella devices are percutaneously inserted ventricular assist devices which require a continuous purge solution that contains heparin to prevent pump thrombosis and device failure. We describe 2 patients with heparin-induced thrombocytopenia (HIT) supported with an Impella device utilizing an argatroban-based purge solution. Case 1 involved an 83-year-old female with biventricular failure which resulted in right ventricle Impella support. The purge solution was changed to include argatroban due to concern of device clotting in the setting of HIT. Case 2 involved a 55-year-old male with worsening cardiogenic shock which resulted in left ventricle Impella support. Due to decreased purge flow rates and concerns for clotting, argatroban was added to the purge solution. Both patients’ total argatroban regimens were monitored and adjusted by pharmacy, resulting in therapeutic anticoagulation without any major bleeding or thrombotic events. Subsequently, a protocol was designed and implemented. These case reports appear to demonstrate the safe and effective use of argatroban purge solutions for the necessary anticoagulation with an Impella device. Further studies are needed to confirm these results and determine the optimal dosing regimen.
Aging, Health, and Quality of Life for Older People Living With HIV in Sub-Saharan Africa: A Review and Proposed Conceptual Framework
Authors: Siedner Mark J.
Published: August 2017

Objective: The number of people living with HIV (PLWH) over 50 years old in sub-Saharan Africa is predicted to triple in the coming decades, to 6-10 million. Yet, there is a paucity of data on the determinants of health and quality of life for older PLWH in the region. Methods: A review was undertaken to describe the impact of HIV infection on aging for PLWH in sub-Saharan Africa. Results: We (a) summarize the pathophysiology and epidemiology of aging with HIV in resource-rich settings, and (b) describe how these relationships might differ in sub-Saharan Africa, (c) propose a conceptual framework to describe determinants of quality of life for older PLWH, and (d) suggest priority research areas needed to ensure long-term gains in quality of life for PLWH in the region. Conclusions: Differences in traditional, lifestyle, and envirnomental risk factors, as well as unique features of HIV epidemiology and care delivery appear to substantially alter the contribution of HIV to aging in sub-Saharan Africa. Meanwhile, unique preferences and conceptualizations of quality of life will require novel measurement and intervention tools. An expanded research and public health infrastructure is needed to ensure that gains made in HIV prevention and treamtent are translated into long-term benefits in this region.
Robust adaptive anti-slip regulation controller for a distributed-drive electric vehicle considering the driver’s intended driving torque
Authors: Yu Zhuoping , Zhang Renxie , Lu Xiong , Jin Chi , Sun Kai
Published: August 2017

A robust adaptive anti-slip regulation controller which consists of two components, namely a road friction coefficient estimator and a wheel dynamics controller, is designed for distributed-drive electric vehicles. The road friction coefficient estimator is based on the latest non-affine parameter estimation theory to achieve the peak road friction coefficient. Also, working conditions for the road friction coefficient estimator are proposed to avoid the estimation error caused by a small slip ratio. According to the results of the road friction coefficient estimator, the desired reference slip ratio is obtained and the key parameters of the robust adaptive anti-slip regulation controller are modified to make sure that the road conditions can be made full use of. Then, according to the desired reference slip ratio, a state feedback control law with a conditional integrator is designed on the basis of the Lyapunov stability theory for a wheel dynamics controller by analysis of the non-linear characteristics of the tyres and the driver’s intended driving torque and constraints from the ground–tyre adhesion. In addition, it achieves smooth switching between optimal driving and the driver’s intended driving torque rather than normal switching logic. Multi-condition simulations and experiments show that the controller is adaptive to different road conditions, can improve the driving efficiency of the vehicle and can ensure stability of the vehicle. Finally, with comparative experiments, the distributed-drive electric vehicle with a robust adaptive anti-slip regulation controller proves to be more efficient than the traditional vehicle with a traditional anti-slip regulation controller.

Published: August 2017

Amanita exitialis is a lethal mushroom found in China. Knowledge regarding taxonomic characterization, toxin detection, general poisoning conditions, clinical manifestations, laboratory examinations, and clinical treatments for this species is currently lacking. We investigated three A. exitialis mushroom poisoning cohorts in Yunnan Province in 2014 and 2015, involving 10 patients. Mushroom samples were identified by morphological and molecular studies. Ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry was used to detect the peptide toxins in the mushroom samples. Epidemiological information, clinical data, and results of laboratory examinations were collected and analyzed. The mushroom samples were all identified as A. exitialis. The average toxin concentration decreased from the cap to the stipe to the volva, and the average concentration of the peptide toxins decreased in the order of α-amanitin > phallacidin > β-amanitin > γ-amanitin. The latency period between ingestion and the onset of symptoms was 13.9 ± 2.1 h, and the time from ingestion to hospitalization was 49.6 ± 8.5 h. The most common symptoms were nausea and vomiting (100%). Four patients died from fulminant hepatic failure. Laboratory examinations showed that the alanine transaminase, aspartate transaminase, prothrombin time, and activated partial thromboplastin time levels peaked on the third day post-ingestion. Total bilirubin and direct bilirubin values peaked on day 7. The death group and the survival group had a similar variation trend of serological indexes, but the death group had a greater change. A. exitialis is an extremely dangerous mushroom and there is a need to educate the public to avoid picking and eating wild mushrooms that have not been definitively identified.
Improved conditional imputation for linear regression with a randomly censored predictor
Authors: Atem Folefac D , Sampene Emmanuel , Greene Thomas J
Published: August 2017

This article describes a nonparametric conditional imputation analytic method for randomly censored covariates in linear regression. While some existing methods make assumptions about the distribution of covariates or underestimate standard error due to lack of imputation error, the proposed approach is distribution-free and utilizes resampling to correct for variance underestimation. The performance of the novel method is assessed using simulations, and results are contrasted with methods currently used for a limit of detection censored design, including the complete case approach and other nonparametric approaches. Theoretical justifications for the proposed method are provided, and its application is demonstrated through a study of association between lipoprotein cholesterol in offspring and parental history of cardiovascular disease.

Published: August 2017

Shopping mall is a group of retail stores under one roof. Malls have been constantly adapting and changing in both style and substance in order to attract increasingly sophisticated and fickle consumers. There are various factors which might affect shoppers’ selection of a place to shop. The present study is an attempt in this regard with special reference to Indian context. The objective of this study was to identify the factors affecting selection criterion of consumers with respect to shopping malls. Mall intercept survey was conducted to identify the factors which influence the selection of shopping malls in multiple cities. The sample included 181 active mall shoppers. Total seven factors which influence the selection of shopping malls from consumer’s view point were identified with a structure questionnaire. Study will help the mall owners and the retail marketers to understand the insights of shoppers that on what basis consumers select the shopping malls for shopping. On these bases, they can plan their strategies for shopping malls.

Preschool Teachers’ Use of Music in the Classroom: A Survey of Park District Preschool Programs
Authors: Rajan Rekha S.
Published: August 2017

The purpose of this study was to explore how preschool teachers use music and identify the types of music activities available to children in their classrooms. Preschool teachers ( N = 178) at park district programs throughout a large state in the American Midwest responded to an online questionnaire. Although teachers acknowledged using music every day, examples of music activities were primarily teacher-directed such as singing along to CDs or following music cues. Teachers also used music to build academic connections and to engage children during transitions. Teachers valued music as important to their teaching practice and for its contribution to children’s learning and development, but cited limited resources, a self-reported lack of music ability, and an absence of knowledge of the standards for music education, as inhibiting their use of child-centered music activities. Implications for teacher preparation and professional development course work in early childhood and music teacher education are discussed.
Providing Culturally Competent Care for LGBTQ Youth in School-Based Health Centers: A Needs Assessment to Guide Quality of Care Improvements
Authors: Garbers Samantha , Heck Craig J. , Gold Melanie A. , Santelli John S. , Bersamin Melina
Published: August 2017

School-based health centers (SBHCs) can take specific steps to provide culturally competent care for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth, potentially impacting well-being. A needs assessment survey was conducted among a convenience sample of SBHC administrators and medical directors to assess climates and actions supportive of LGBTQ quality medical care. Half (53%) of the SBHCs surveyed ( N = 66) reviewed print materials for negative LGBTQ stereotypes, and 27.3% conducted exhaustive materials review. Regional differences were detected: 46.2% of Southern SBHCs conducted any materials review compared to 91.3% in the West and all in the East and Midwest (χ2, p < .001). In the last academic year, 45.5% conducted no medical provider trainings, and 54.5% conducted no general staff trainings on providing care for LGBTQ youth. On intake forms, 85.4% included preferred names, but only 23.5% included preferred pronoun. There are significant gaps in the extent to which SBHCs provide culturally competent care. These findings can guide future training and advocacy.

The Wielding Influence of Political Networks: Representation in Majority-Latino Districts
Authors: Ocampo Angela X.
Published: August 2017

Latino-majority congressional districts are far more likely to elect Latino representatives to Congress than majority-white districts. However, not all majority-Latino districts do so. This paper addresses this question, and it investigates how the level of influence of political parties and interest groups in majority-Latino districts substantially shapes Latino representation to the US House of Representatives. I rely on five case studies and a dataset of candidates to open congressional races with a Latino population plurality from 2004 to 2014. The evidence indicates that groups and political networks are critical for Latina/o candidate recruitment, the organization of resources in a congressional district, the deployment of campaign resources on behalf of certain candidates, and the eventual success of Latina/o candidates. The findings suggest that Latino descriptive and substantive representation are shaped by the wielding influence of political parties and interest groups.

Published: August 2017

Heterotopic gastric mucosa in biliary tract is a congenital anomaly that can prove significant clinical dilemmas. Here we report the case of a 28-year-old female patient presenting with jaundice, pruritus, and altered liver tests, with predominant cholestasis. Liver biopsy revealed histological changes suggesting large bile duct obstruction with advanced fibrosis. At imaging, common hepatic duct stricture due to an intraluminal enhancing mass was observed. Endoscopic retrograde cholangiopancreatography and upper echoendoscopy revealed a firm mass of the common hepatic duct with a complete obstruction, suspicious for cholangiocarcinoma. Fine-needle aspiration biopsy performed under echoendoscopic guidance revealed fundic type gastric mucosa. Despite histological result, radiological suspicion of malignancy together with advanced fibrosis prompted a segmental resection of biliary tract. At macroscopic examination, the common hepatic duct presented a focal pseudocystic appearance with a firm zone of subtotal stenosis. Histology revealed a duplication cyst lined by heterotopic fundic gastric mucosa. Heterotopic gastric mucosa of the biliary tract should be suspected in young patients without know risk factors for hepatobiliary malignancies. Imaging and careful histological examination are mandatory for optimal management. Liver fibrosis, secondary to chronic biliary obstruction may be a significant late complication.
How Do Hunter-Gatherer Children Learn Social and Gender Norms? A Meta-Ethnographic Review
Authors: Lew-Levy Sheina , Lavi Noa , Reckin Rachel , Cristóbal-Azkarate Jurgi , Ellis-Davies Kate
Published: August 2017

Forager societies tend to value egalitarianism, cooperative autonomy, and sharing. Furthermore, foragers exhibit a strong gendered division of labor. However, few studies have employed a cross-cultural approach to understand how forager children learn social and gender norms. To address this gap, we perform a meta-ethnography, which allows for the systematic extraction, synthesis, and comparison of quantitative and qualitative publications. In all, 77 publications met our inclusion criteria. These suggest that sharing is actively taught in infancy. In early childhood, children transition to the playgroup, signifying their increased autonomy. Cooperative behaviors are learned through play. At the end of middle childhood, children self-segregate into same-sex groups and begin to perform gender-specific tasks. We find evidence that foragers actively teach children social norms, and that, with sedentarization, teaching, through direct instruction and task assignment, replaces imitation in learning gendered behaviors. We also find evidence that child-to-child transmission is an important way children learn cultural norms, and that noninterference might be a way autonomy is taught. These findings can add to the debate on teaching and learning within forager populations.
Designing Journalists: Teaching Journalism Students to Think Like Web Designers
Authors: Gyori Bradford , Charles Mathew
Published: August 2017

The authors introduced 80 university-level journalism students to a web design program called Klynt and supervised the creation of multiple interactive documentaries. They discovered that fledgling reporters could effectively design interactive media while creating work that reflects their own candid and extemporaneous ethos. Building on the insight that journalism in the digital age must give rise to modified best practices, this study examines the complex production processes from which multiple i-docs emerged. The authors conclude by suggesting four tentative “new best practices” for journalists attempting to think and act like web designers.
Journalism Education in India: Quest for Professionalism or Incremental Responses
Authors: Bharthur Sanjay Parthasarathy
Published: August 2017

Journalism education in India is framed in the higher education system, comprising of programs in the universities, both government-supported and media-backed private institutions, as well as in-service and short-term courses offered by press associations and other organizations. They are offered at different levels from certificate to diploma to both undergraduates and postgraduates. Due to requirements of the media industry, there is a constant friction about the need to balance the academic and professional aspects in the curriculum. This has led to skepticism in the past about the relevance of formal journalism education. However, with globalization and growth of the media sector, there is an enhanced need for professionals. Many big media groups have launched journalism programs. Institutional and professional aspects of the programs in India and issues pertaining to curriculum, responses, and critique have been factored in this article.
Why do travel agencies choose to undergo IPOs in Taiwan?
Authors: Huang Leo , Chang Michael
Published: August 2017

Travel agencies have seen an increasing number of firms going public in recent years. This study explores and empirically examines the initial public offering (IPO) strategy model for travel agencies by adopting a three-round Delphi research design. Qualitative interviews with the 13 travel agency chief executive officers and related experts provided additional insights. The result shows that Taiwanese travel agencies consider 9 internal motivations, 8 external environment forces, and 11 determinants for the decision to go IPO and 10 performance indicators post-IPO. Finally, the model herein illustrates how travel agencies can realize IPOs’ strategic goals by increasing the performance of travel agency post-IPO.
The role of distance in the peer-to-peer market for tourist accommodation
Authors: Benítez-Aurioles Beatriz
Published: August 2017

This article provides evidence on the concentration of peer-to-peer tourist accommodations in the center of cities and the role of distance. On that basis, an explanatory model is proposed to understand the locating decisions of the different agents involved. The model is empirically implemented through a two-stage least squares regression, which allows estimating the elasticity of demand with respect to price and distance. Results for the Spanish cities of Barcelona and Madrid confirm similar price elasticity of demand in both (2.2 and 2.4, respectively) but greater sensibility of demand with respect to distance to the center in the former.
Exploring customer engagement in tourism
Authors: Romero Jaime
Published: August 2017

Customer engagement (CE) creates economic value for tourism firms. However, tourism companies still lack enough knowledge to properly measure CE and manage its drivers. We address this gap by proposing a behavioural CE measurement and by exploring some of the antecedents on this construct (relationship quality, rewards, company identification, self-enhancement, learning and social integration). We test our propositions using survey data (466 respondents). Our results provide empirical support for our proposed CE construct, while corroborating four of the six hypothesized antecedents. In closing, we discuss theoretical and managerial implications, study limitations and future research directions.
The social inequalities of Internet access, its use, and the impact on children’s academic performance: Evidence from a longitudinal study in Switzerland
Authors: Camerini Anne-Linda , Schulz Peter J , Jeannet Anne-Marie
Published: August 2017

This longitudinal study explores differences in Internet access and use among school-aged children in Italian-speaking Switzerland and whether and how these differences contribute to inequalities in academic performance. Applying multilevel structural equation modeling with two-wave original survey data from 843 students, their parents, as well as students’ end-term school grades, we show that a family’s socio-economic status indirectly affects children’s school grades as lower parental income leads children to use the Internet more frequently for entertainment and online communication purposes. This form of Internet use also increases as children have more personal digital media devices. As children’s increased use of the Internet for entertainment and online communication worsens their academic performance, our results suggest that social inequalities due to children’s socio-economic status are reinforced by a second-order digital divide. We discuss potential reasons for our findings as well as their implications and recommendations for possible interventions.
Uniform multilingualism: A media genealogy of Google Translate
Authors: Ramati Ido , Pinchevski Amit
Published: August 2017

This article applies a media geneaology perspective to examine the operative logic of Google Translate. Tracing machine translation from post–World War II (WWII) rule-based methods to contemporary algorithmic statistical methods, we analyze the underlying power structure of algorithmic and human collaboration that Translate encompasses. Focusing on the relationship between technology, language, and speakers, we argue that the operative logic of Translate represents a new model of translation, which we call uniform multilingualism. In this model, the manifest lingual plurality on the user side is mediated by lingual uniformity on the system side in the form of an English language algorithm, which has recently given way to an artificial neural network interlingual algorithm. We conclude by considering the significance of this recent shift in Translate’s algorithm.
Journalism under attack: The Charlie Hebdo covers and reconsiderations of journalistic norms
Authors: Jenkins Joy , Tandoc Edson C
Published: August 2017

In January 2015, masked gunmen attacked the satirical French newspaper Charlie Hebdo. The events presented an ethical dilemma for news organizations around the world, which had to determine whether to republish controversial images from Charlie Hebdo’s history. Many US news organizations explained their ethical decision-making in their own publications or provided interviews to other news agencies reporting about the disagreement. This study is based on a qualitative textual analysis of 35 articles from news outlets in the United States published within a month after the attacks. The analysis considers the journalistic norms and boundaries underlying the news organizations’ decisions to republish or withhold the images and how these norms shape assumptions about journalistic professionalism.
How do they do it? Multimedia journalism and perceptions of the practice
Authors: Kartveit Kate
Published: August 2017

Implementing a phenomenographic approach, the question this article seeks to answer is how experienced journalists, editors and graphic designers perceive how multimedia journalism is executed. The study is based on qualitative interviews with experienced media workers who work with or manage work within online multimedia off-deadline feature journalism in mainstream online media outlets. In the outcome space, I categorise six different perceptions describing collective approaches to multimedia production: the learner, the developer, the artist, the collaborator, the publisher and the manager. Conclusively, these collective perceptions can influence how competencies are developed and how the workflow of multimedia production is implemented and organised in editorial rooms and educational situations.
When Older People Are Violent or Abusive Toward Their Family Caregiver: A Review of Mixed-Methods Research
Authors: Isham Louise , Hewison Alistair , Bradbury-Jones Caroline
Published: August 2017

What happens when family caregivers experience violence and abuse from the older person for whom they care? Although this issue has received little global attention, it is relevant to researchers, practitioners, and policy makers working across the intersecting fields of older age care and medicine, adult protection and safeguarding, and domestic and intimate partner violence. To date, these fields have generated diverse explanations of violence and abuse in older age illness and how best to respond to it. This article reports the findings of a systematic literature review of 18 quantitative, qualitative, and mixed-methods studies that investigated violent and abusive behavior by older people toward their family caregivers. The review identified three central themes in the literature: (1) There are inconsistent definitions and measurements used in research about harmful, violent, and abusive behavior toward family caregivers. (2) Violent and abusive behavior toward caregivers is a sensitive and hidden topic that poses practical and methodological challenges for researchers. (3) There is some evidence to suggest that people who were violent and abusive in their earlier life—or who had a poor relationship with their family member in the past—are more likely to continue to experience violence and abusive behavior in later life. There were two central ways in which violence and abuse were conceptualized and investigated: as a “symptom of illness” or as an “act of abuse” and we present a visual map of the relationship between these two conceptualizations drawn from our analysis of the literature. We conclude by discussing the implications of the findings and recommend future directions for practice, research, and policy to support affected families.
Usefulness of Lipoprotein(a) for Predicting Clinical Outcomes After Endovascular Therapy for Aortoiliac Atherosclerotic Lesions

Published: August 2017

Purpose: To evaluate the usefulness of serum lipoprotein(a) as a biomarker of clinical outcomes after endovascular therapy (EVT) for atherosclerotic aortoiliac lesions. Methods: Serum lipoprotein(a) concentrations were measured at admission in 189 consecutive patients (median age 72 years; 160 men) with peripheral artery disease who underwent EVT for aortoiliac occlusive disease. The patients were dichotomized into 2 groups based on serum lipoprotein(a) levels ≤40 mg/dL (LOW; n=135) or >40 mg/dL (HIGH; n=54). After EVT, the incidences of major adverse limb events (MALE) were analyzed. Predictors of MALE were sought with a Cox proportional hazards analysis; results are presented as the hazard ratio (HR) and 95% confidence interval. Results: At the median follow-up of 33 months (interquartile range 11, 54), MALE occurred in 44 (23.3%) patients. The MALE-free survival estimate was significantly lower in patients in the HIGH group (55.6% vs 85.2%, p<0.001). Independent predictors of MALE after EVT were hemodialysis (HR 2.23, 95% CI 1.04 to 4.78, p=0.039) and high lipoprotein(a) levels (HR 2.80, 95% CI 1.44 to 5.45, p=0.003). Conclusion: High lipoprotein(a) levels were associated with a higher incidence of MALE after EVT for patients with aortoiliac lesions.
African American Men With Low-Risk Prostate Cancer Are Candidates for Active Surveillance: The Will-Rogers Effect?
Authors: Qi Robert , Moul Judd
Published: August 2017

It is controversial whether African American men(AAM) with low-risk prostate cancer (PC) should be placed on active surveillance (AS). Recent literature indicates AAM diagnosed with low-risk disease have increased pathologic upgrading and disease progression. We evaluated the surgical pathology of AAM and Caucasians who underwent prostatectomy to assess the suitability of AAM for AS. We retrospectively reviewed 1,034 consecutive men who underwent open prostatectomy between 2004 and 2015; 345 Caucasians and 58 AAM met the American Urological Association criteria for low-risk PC. We excluded from analysis two men whose prostatectomies were aborted. Chi-square test, Fisher’s exact test, and Wilcoxon rank sum test were used for statistical analysis. AAM with low-risk PC have a lower rate of surgical upgrading and similar rates of adverse pathology compared with Caucasians. 29.8% of AAM (17/57) diagnosed with low-risk disease but 44.5% of Caucasians (153/344) had disease upgrading at prostatectomy ( p < .04), although AAM overall were less likely to be clinically diagnosed with low-risk cancer (33.1 vs. 41.7%, p < .05). AAM with low-risk pathology were younger (median 55 vs. 59 years, p < .001) and had smaller prostates (32 vs. 35 g, p < .04). AAM with preoperative low-risk disease have lower rates of surgical upgrading and similar adverse pathology compared with Caucasians. There may be a Will-Rogers effect as AAM with aggressive disease appear more likely to be stratified into intermediate- and high-risk groups, leaving those AAM diagnosed with low-risk disease fully eligible for AS. Our results support that AS for AAM should remain a viable option.

Background: Grip strength is a performance-based measure of upper extremity function that might be influenced by priming (the influence of a response to a stimulus by exposure to another stimulus). This study addressed the influence of questionnaire content on performance measurements such as grip strength between patients who complete the standard Pain Catastrophizing Scale (PCS) compared with patients who complete a positively adjusted PCS. Methods: Between June 2015 and August 2015, we enrolled 122 patients who presented to 3 hand surgeons at 3 outpatient offices. They were randomized to 2 groups: the control group, which completed the PCS, and the intervention group, which completed a positively phrased version of the PCS. Before and after completion of the questionnaire, we measured each patient’s grip strength 3 times by alternating between hands. Two patients were excluded after participation. We calculated both the preintervention and postintervention mean and maximum grip strengths. Results: There was no significant difference between groups on mean or maximum grip strength before completion of the questionnaires. There was a greater improvement in mean grip strength of both hands in the intervention group compared with the PCS group. This improvement was statistically significant in the affected hand. The maximum grip strength showed a statistically significant greater improvement in both hands in the positive PCS group compared with the control group. Conclusions: Positive priming through a questionnaire leads to an increase in mean and maximum grip strength when compared with the standard questionnaire that uses negative terms rather than positive.

Backround:

Left atrial (LA) enlargement plays an important role in the development of heart failure (HF) and is a robust prognostic factor. Fibrotic processes have also been advocated to evoke HF through finite signalling proteins.

Methods:

We examined the association of two such proteins, cystatin C (CysC) and galectin-3 (Gal-3), and other clinical, echocardiographic and biochemical parameters with LA volume index (LAVi) in patients with HF with severely impaired left ventricular ejection fraction (LVEF). Severe renal, liver, autoimmune disease and cancer were exclusion criteria.

Results:

A total of 40 patients with HF (31 men, age 66.6 ± 1.7) with LVEF = 25.4 ± 0.9% were divided into two groups according to the mean LAVi (51.03 ± 2.9 ml/m2) calculated by two-dimensional transthoracic echocardiography. Greater LAVi was positively associated with LV end-diastolic volume ( p = 0.017), LV end-systolic volume ( p = 0.025), mitral regurgitant volume (MRV) ( p = 0.001), right ventricular systolic pressure (RVSP) ( p < 0.001), restrictive diastolic filling pattern ( p = 0.003) and atrial fibrillation ( p = 0.005). Plasma CysC was positively correlated with LAVi ( R2 = 0.135, p = 0.019) and log-transformed plasma Gal-3 ( R2 = 0.109, p = 0.042) by simple linear regression analysis. Stepwise multiple linear regression analysis showed that only MRV ( t = 2.236, p = 0.032), CysC ( t = 2.467, p = 0.019) and RVSP ( t = 2.155, p = 0.038) were significant predictors of LAVi.

Conclusions:

Apart from known determinants of LAVi, circulating CysC and Gal-3 were associated with greater LA dilatation in patients with HF with reduced LVEF. Interestingly, the correlation between these two fibrotic proteins was positive.
The relationship between press release and newspaper coverage of tobacco-related issues in South Korea
Authors: Cho Kyung Sook , Yoon Jangho
Published: August 2017

This study investigates an association between press release and news media response on tobacco-related issues in South Korea. We retrieved 231 tobacco-related newspaper articles from all major dailies throughout the year 2005. In total, 37 press releases on tobacco-related issues and policies published by the Korea Ministry of Health and Welfare were obtained from the Ministry website. Content analysis and appropriate statistical tests were performed. Results from our content analysis suggest that producing more press releases on tobacco-related issues may result in a greater volume of newspaper articles, and that a press release on a new topical issue may effect more intense media coverage. Findings also show that when Korean newspaper articles overall held less favorable views of tobacco-related policies and programs in 2005, taxation was the most frequent theme with a non-positive opinion. Findings from our multivariate logistic regression models imply that a newspaper article with a source press release—especially about a new topical issue—is more likely than an article without a source press release to discuss tobacco-related issues more positively. Our findings suggest that a press release may serve as an effective media strategy for reaching out to the public by disseminating tobacco-control efforts and policies.
Health promotion and sustainability programmes in Australia: barriers and enablers to evaluation
Authors: Patrick Rebecca , Kingsley Jonathan
Published: August 2017

In an era characterised by the adverse impacts of climate change and environmental degradation, health promotion programmes are beginning to actively link human health with environmental sustainability imperatives. This paper draws on a study of health promotion and sustainability programmes in Australia, providing insights to evaluation approaches being used and barriers and enablers to these evaluations. The study was based on a multi-strategy research involving both quantitative and qualitative methods. Health promotion practitioners explained through surveys and semi-structured interviews that they focused on five overarching health and sustainability programme types (healthy and sustainable food, active transport, energy efficiency, contact with nature, and capacity building). Various evaluation methods and indicators (health, social, environmental, economic and demographic) were identified as being valuable for monitoring and evaluating health and sustainability programmes. Findings identified several evaluation enablers such as successful community engagement, knowledge of health and sustainability issues and programme champions, whereas barriers included resource constraints and competing interests. This paper highlights the need for ecological models and evaluation tools to support the design and monitoring of health promotion and sustainability programmes.
