Alignment between institutions and graduate medical education (GME) regarding quality and safety initiatives (QI) has not been measured. The objective was to determine US internal medicine residency program directors’ (IM PDs) perceived resourcing for QI and alignment between GME and their institutions. A national survey of IM PDs was conducted in the Fall of 2013. Multivariable linear regression was used to test association between a novel Integration Score (IS) measuring alignment between GME and the institution via PD perceptions. The response rate was 72.6% (265/365). According to PDs, residents were highly engaged in QI (82%), but adequate funding (14%) and support personnel (37% to 61%) were lower. Higher IS correlated to reports of funding for QI (76.3% vs 54.5%, P = .012), QI personnel (67.3% vs 41.1%, P < .001), research experts (70.5% vs 50.0%, P < .001), and computer experts (69.0% vs 45.8%, P < .001) for QI assistance. Apparent mismatch between GME and institutional resources exists, and the IS may be useful in measuring GME–institutional leadership alignment in QI.

Authors: Dimakakos Evangelos P. , Vathiotis Ioannis , Syrigos Konstantinos
Published: November 2017

Current guidelines recommend low-molecular-weight heparin treatment in patients with cancer with established venous thromboembolism (VTE). The aim of this article was to study the pharmacological properties and effectiveness of tinzaparin in patients with cancer as well as its potential anticancer properties. A search of PubMed and ScienceDirect databases up to March 2016 was carried out to identify published studies that detect the properties and use of tinzaparin in oncology. Protamine sulfate partially (60% to 65%) neutralized tinzaparin’s anti-Xa activity. No dose adjustment of tinzaparin is needed even in patients with severe renal impairment and Creatinine Clearance ≥20 mL/min. Tinzaparin demonstrated a statistically significant decline in VTE recurrence at 1 year post the index thromboembolic event. A statistically significant reduction in minor bleeding rates was also described, whereas major bleeding events did not decrease in patients with cancer treated with tinzaparin versus those who received vitamin K antagonists. Tinzaparin treatment in patients suffering from deep vein thrombosis reduced the incidence of postthrombotic syndrome and venous ulcers. Tinzaparin’s ability to prevent both metastatic dissemination of cancer cells and tumor angiogenesis has been delineated in preclinical research. Current data show that tinzaparin is safe and efficacious either for short-term or for long-term treatment of VTE in patients with cancer. Clinical trials are needed in order to examine the utility of tinzaparin in primary prevention of VTE and validate its potential anticancer advantages exhibited in preclinical research.

Published: November 2017

Objective:To evaluate participants’ perceptions about frequent use and reasons for substance use (SU) in the qualitative interview study, an add-on to the multimodal treatment study of ADHD (MTA). Method: Using the longitudinal MTA database, 39 ADHD cases and 19 peers with Persistent SU, and 86 ADHD cases and 39 peers without Persistent SU were identified and recruited. In adulthood, an open-ended interview was administered, and SU excerpts were indexed and classified to create subtopics (frequent use and reasons for use of alcohol, marijuana, and other drugs). Results: For marijuana, the Persistent compared with Nonpersistent SU group had a significantly higher percentage of participants describing frequent use and giving reasons for use, and the ADHD group compared with the group of peers had a significantly higher percentage giving “stability” as a reason for use. Conclusion: Motivations for persistent marijuana use may differ for adults with and without a history of ADHD.
YouTube celebrities and parasocial interaction: Using feedback channels in mediatized relationships
Authors: Rihl Alexander , Wegener Claudia
Published: November 2017

Young media consumers are increasingly using online video platforms, as YouTube in particular registers extremely high numbers of viewers and subscribers. These numbers then increase the popularity of the celebrities who present themselves in the videos on the platform. With their far-reaching influence, through involvement in the public sphere as well as broad marketing concepts, they draw in viewers and gain attention worldwide. It can thus be understood that YouTube users also form a bond with the celebrities featured online, as formulated theoretically in the concept of parasocial relationships. In this study, an exploratory online survey examines quantitatively whether these parasocial relationships are predominantly formed with YouTubers via the platform’s feedback channels. As the results show, however, the strength of these parasocial relationships is not influenced to any great extent by use of the feedback functions.
Expressed emotion in couples facing breast cancer in women is associated with psychological distress in the first year after surgery
Authors: Favez Nicolas , Cairo Notari Sarah , Antonini Tania , Charvoz Linda
Published: November 2017

The aim of this study was to assess the links between partners’ and women’s expressed emotion with the distress of one another during the first year after surgery for breast cancer in women. The design was longitudinal. A sample of 61 couples participated in the study at 2 weeks, 3 months, and 12 months after the surgery. Expressed emotion was assessed with the Five-Minute Speech Sample. Psychological distress was assessed with a self-reported questionnaire. Mixed-model analyses showed that partners’ expressed emotion is associated with heightened psychological distress in women during the first year after surgery, even after medical data were controlled for.
Depression at work, authenticity in question: Experiencing, concealing and revealing
Authors: Ridge Damien , Broom Alex , Kokanović Renata , Ziebland Sue , Hill Nicholas
Published: November 2017

Australia and the United Kingdom have introduced policies to protect employees who experience mental illness, including depression. However, a better understanding of the experiential issues workers face (e.g. sense of moral failure) is needed for the provision of appropriate and beneficial support. We analysed 73 interviews from the United Kingdom and Australia where narratives of depression and work intersected. Participants encountered difficulties in being (and performing as if) ‘authentic’ at work, with depression contributing to confusions about the self. The diffuse post-1960s imperative to ‘be yourself’ is experienced in conflicting ways: while some participants sought support from managers and colleagues (e.g. sick leave, back-to-work plans), many others put on a façade in an attempt to perform the ‘well’ and ‘authentic’ employee. We outline the contradictory forces at play for participants when authenticity and visibility are expected, yet, moral imperatives to be good (healthy) employees are normative.
Provisionally pregnant: uncertainty and interpretive work in accounts of home pregnancy testing
Authors: Ross Emily
Published: November 2017

Upon their availability for purchase in the 1970s, home pregnancy testing devices were hailed as a ‘revolution’ for women’s reproductive rights. Some authors, however, have described these technologies as further enabling the medicalisation of pregnancy and as contributing to the devaluing of women’s embodied knowledge. The home pregnancy test is one of many technological devices encountered by women experiencing pregnancy in the United Kingdom today. Existing literature has described how engagement with medical technologies during pregnancy might address uncertainties experienced at this time, providing women with reassurance and alleviating anxieties. Drawing on interviews with women living in Scotland, this article explores accounts of testing for a first pregnancy, and women’s descriptions of the impacts of home pregnancy testing upon experiences of early gestation. Participants engaged with pregnancy tests in varying ways, with uses shaping and shaped by their experiences of early pregnancy more broadly. Particular technical characteristics of the home pregnancy test led many participants to question their interpretation of a positive result, as well as the accuracy of the test itself. Rather than addressing the unknowns of early gestation by confirming a suspected pregnancy, a positive result could thus exacerbate uncertainty. Through participants’ accounts, this article shows how uncertainty is lived out by users of mundane techno-medical artefacts and sheds new light on women’s experiences of the first trimester of pregnancy.
Visibility, resilience, vulnerability in young migrants
Authors: Bradby Hannah , Liabo Kristin , Ingold Anne , Roberts Helen
Published: November 2017

Young unaccompanied asylum seekers have been portrayed as vulnerable, resilient or both. Those granted residency in Europe are offered support by health and social care systems, but once they leave the care system to make independent lives, what part can these services play? Our review of research with migrants who have been in care in Sweden and the United Kingdom found evidence of unmet need, but little research describing their own views of services. The limited published evidence, supplemented by interviews with care leavers in a UK inner city, suggests that in defining health needs, young people emphasise housing, education, employment and friendship over clinical or preventative services. Some felt well supported while others described feeling vulnerable, anxious, angry or sad. These experiences, if linked with the insensitivity of even one professional, could lower young people’s expectations of healthcare to the extent that they avoided contact with service providers. In supporting young migrants’ resilience to meet everyday challenges, friendly support from peers, carers and professionals was important. They needed determined advocacy at key moments. The different challenges for the Swedish and UK health and welfare systems along with the resilience/vulnerability trajectory are described.
‘Normal’ and ‘failing’ mothers: Women’s constructions of maternal subjectivity while living with multiple sclerosis
Authors: Parton Chloe , Katz Terri , Ussher Jane M
Published: November 2017

Multiple sclerosis causes physical and cognitive impairment that can impact women’s experiences of motherhood. This study examined how women construct their maternal subjectivities, or sense of self as a mother, drawing on a framework of biographical disruption. A total of 20 mothers with a multiple sclerosis diagnosis took part in semi-structured interviews. Transcripts were analysed using thematic decomposition to identify subject positions that women adopted in relation to cultural discourses of gender, motherhood and illness. Three main subject positions were identified: ‘The Failing Mother’, ‘Fear of Judgement and Burdening Others’ and ‘The Normal Mother’. Women’s sense of self as the ‘Failing Mother’ was attributed to the impact of multiple sclerosis, contributing to biographical disruption and reinforced through ‘Fear of Judgement and Burdening Others’ within social interactions. In accounts of the ‘Normal Mother’, maternal subjectivity was renegotiated by adopting strategies to manage the limitations of multiple sclerosis on mothering practice. This allowed women to self-position as ‘good’ mothers. Health professionals can assist women by acknowledging the embodied impact of multiple sclerosis on maternal subjectivities, coping strategies that women employ to address potential biographical disruption, and the cultural context of mothering, which contributes to women’s experience of subjectivity and well-being when living with multiple sclerosis.
Patients’ preferences for new versus old anticoagulants: a mixed-method vignette-based study
Authors: Bajorek Beata , Saxton Brooke , Anderson Elizabeth , Chow Clara K
Published: November 2017

Background:

For both patients and clinicians, differences between older and new anticoagulants have major implications for treatment selection, day-to-day management of therapy and adherence.

Aims:

To explore patients’ preferences for warfarin versus direct oral anticoagulant (DOAC) therapy.

Methods:

Mixed-method study involving anticoagulated older patients admitted to hospital. Part A comprised a vignette-based questionnaire; patients were asked whether they preferred Medicine A (warfarin) or Medicine B (DOAC). Part B interviews explored patients’ satisfaction with their current anticoagulant. Responses were thematically analysed.

Results:

Forty patients participated: 23 warfarin-treated, 17 DOAC-treated. Collectively, Parts A and B identified that most patients were satisfied with their current therapy (warfarin or DOAC), expressing reluctance to change to alternatives. Among patients who were able to numerically rate their satisfaction with therapy, most were ‘satisfied’ with their current anticoagulant, although warfarin-treated patients were slightly less ‘satisfied’ (median score 3.5) than those on DOACs (median score 5.0). Despite this, warfarin-treated patients still preferred their current therapy (over DOACs) due to familiarity and the security of regular international normalised ratio (INR) monitoring; those who preferred DOACs cited previous warfarin-related bleeding and unstable INRs as key reasons. DOAC-treated patients who preferred warfarin perceived regular monitoring as a major advantage; only those having had negative experiences with warfarin clearly preferred DOACs.

Conclusion:

Most patients accepted their currently prescribed anticoagulant, be it warfarin or DOACs. Features of specific anticoagulants, such as regular monitoring with warfarin, were perceived variably – some patients cited them as advantages and others as disadvantages. The clearest preference identified was for the agent already being taken.
Sweating the “small stuff”: High-reliability organizing as a foundation for sustained superior performance
Authors: Vogus Timothy J. , Rerup Claus
Published: November 2017

Achieving and sustaining superior relative performance is central to strategic organization research. Recently, strategic organization researchers have turned their attention to the broader set of people doing strategy work, how they do it, and what contributes to superior performance. We deepen this focus by arguing that operational activity on the front line is strategic. To illustrate how everyday operations become strategic, we draw on insights from high-reliability organizing to illustrate how leaders, through practices and behaviors, support a more strategic front line and a specific set of discursive practices known as mindful organizing. The everyday mindful work of front line operations is a crucial source of emerging opportunities and threats that underlie superior relative performance. We discuss the methodological implications of applying high-reliability organizing approaches to study strategic organization and how strategic organization research can broaden and enrich research on high reliability.
Paradox theory and the paradox of success
Authors: Cunha Miguel Pina e , Putnam Linda L
Published: November 2017

The study of paradox in strategy and organization studies has grown rapidly over the last 25 years. Paradox, as contradictory yet interrelated opposites that exist simultaneously and persist over time, can be qualified as a successful area of study. Yet success, however sweet, may come at a price, namely, premature convergence on theoretical concepts, overconfidence in dominant explanations, and institutionalizing labels that protect dominant logics. We discuss the risk of paradox theory being vulnerable to the paradox of success and focus on ways to avoid narrowness in theory building.
Text and Terror: Monster Theory and the Hebrew Bible
Authors: Grafius Brandon R.
Published: November 2017

While biblical scholars have long been interested in the monsters of the Hebrew Bible, it is only in the last several decades that theoretical approaches to monsters have made their way into biblical studies. Originating in the fields of psychoanalysis and anthropology, monster theory looks at the construction of various monsters, arguing that the way a culture creates its monsters reveals the anxieties held by that culture. This article will explore the uses of monster theory in recent works of biblical scholarship, demonstrating that monster theory has been used to read the figure of the monster as a representation of chaos, identify monstrous imagery as a rhetoric of trauma, and explore how the boundaries between the monster and the self are shifting and unstable.
Ritual Studies and the Study of Rabbinic Literature
Authors: Balberg Mira
Published: November 2017

In the last two decades several important studies have been published that focus on ritual in rabbinic literature, and consider ritual to be a critically important conceptual and analytical category in approaching rabbinic texts and rabbinic culture. This article provides an account of the intersection of Ritual Studies with the study of rabbinic literature, surveys key works and significant developments and shifts in the field, and identifies the central challenges in and benefits of examining rabbinic texts through ritual lenses. The article pays special attention to the complex relations between texts about rituals and ritual performances, as well as to the blurry boundaries between law and ritual in the realm of rabbinic halakhah.
What Has Mark’s Christ to Do with David’s Son? A History of Interpretation
Authors: Botner Max
Published: November 2017

It has become something of a commonplace within recent scholarship on the Gospels to hear that Mark the evangelist is ambivalent about Davidic sonship. Yet, rarely have scholars explored the rationale underlying this ambivalence. This article probes the status quaestionis on Jesus’ Davidic status in Mark’s Gospel via a history-of-interpretation survey of the Davidssohnfrage (Mk 12.35-37). It demonstrates that, despite their varying approaches and ideological commitments, all participants in the Son-of-David debate have assumed a foundational methodological principle: one assesses Mark’s position on Davidic messiahship by isolating pericopes with the name ‘David’. This explains why the healing of blind Bartimaeus (Mk 10.46-52) has long been fixed as the de facto crux interpretum for Davidic sonship in Mark.
Video Games as Dating Platforms: Exploring Digital Intimacies through a Chinese Online Dancing Video Game
Authors: Liu Tingting
Published: November 2017

In the relatively young field of new media studies, both video games and online dating platforms are identified as being important and popular genres of digital products, which are often discussed separately. This article argues that these two genres of digital products are not so much separate but entangled elements of the same processes of technological shifts in media industry, development of people’s online leisure activities, and the convergence of digital genres. To provide empirical evidence, this article examines a Chinese dancing video game, QQ Dazzling Dance (QQ Xuan Wu), which creatively juxtaposes these two genres of participatory digital culture and recognizes the analytical and critical values in doing so.
A Comparison of Two Content Area Curriculum-Based Measurement Tools
Authors: Ford Jeremy W. , Conoyer Sarah J. , Lembke Erica S. , Smith R. Alex , Hosp John L.
Published: November 2017

In the present study, two types of curriculum-based measurement (CBM) tools in science, Vocabulary Matching (VM) and Statement Verification for Science (SV-S), a modified Sentence Verification Technique, were compared. Specifically, this study aimed to determine whether the format of information presented (i.e., SV-S vs. VM) produces differences in alternate form reliability and validity of scores or any differences in accuracy of prediction of scores on the state standardized science assessment. Overall, 25 eighth-grade science students were administered two SV-S and two VM forms with identical items along with spring eighth-grade maze passages from Aimsweb. Students had recently taken the eighth-grade state science test. Results regarding technical adequacy for each CBM tool were consistent with past findings. However, this study extends the literature base on CBM tools in science by providing evidence for using standards to develop VM forms. In addition, despite probable ceiling effects, additional evidence was found for the potential of SV-S as a CBM tool in science.
Bridging the Gap: Direct Behavior Rating–Single Item Scales
Authors: Miller Faith G. , Crovello Nicholas , Swenson Nicole
Published: November 2017

Direct Behavior Ratings (DBRs) are behavioral assessment methods that combine the benefits of systematic direct observation and behavior rating scales. That is, DBRs involve the observation of operationally defined target behaviors during a prespecified observation period and the evaluation of those behaviors via brief ratings. In this way, DBR is considered a hybrid assessment method. This article describes the landscape of DBR tools and provides an overview of the procedures and research currently available to support the use of one specific version, DBR–Single Item Scales (DBR-SIS), for progress monitoring within multi-tiered systems of support.
Evidence-Based Assessment and Single-Case Research: A Commentary for the Special Issue on Direct Behavior Ratings
Authors: Maggin Daniel M. , Bruhn Allison
Published: November 2017

The purpose of this commentary is to provide observation on the contributions to the special issue and remark on the broader implications of the research. As noted throughout the special issue, the intent was to demonstrate the use of progress monitoring within a problem-solving framework to evaluate student social and behavioral development using direct behavior ratings (DBR). Leveraging single-case research methods through adherence to the What Works Clearinghouse (WWC) standards, the articles included in the special issue provide examples for using DBR to assess student response-to-intervention while also illustrating a number of psychometric considerations that can strengthen the evidence base for progress-monitoring tools more broadly. In this commentary, we argue that the research included in the special issue provides a framework for conceptualizing evidence-based assessment for progress-monitoring instruments using single-case methods. Toward this end, the commentary provides an overview of the concept of evidence-based assessment and uses examples from the included studies to describe various facets.

Authors: Looby Maureen Ayers , Vogel Rachel Isaksson , Bangdiwala Ananta , Hyer Barbara , Das Kamalini
Published: November 2017

Objective. Negative pressure therapy (NPT) offers the potential to reduce infection in obese patients. The goal of this study was to explore the association between NPT use and infection after cesarean delivery among obese women. Methods: We initiated a hospital protocol wherein women with a body mass index (BMI) of 40 kg/m2 or greater who delivered after January 1, 2011 were to receive NPT following cesarean section. A retrospective comparison of surgical site infection (SSI) in women receiving the intervention to a similar group with a BMI of 40 kg/m2 or greater, a historical control group of women who delivered before January 1, 2011. Incidence of SSI was compared between time periods using logistic regression models. Results. A total of 233 patients in the preintervention (control) group and 234 patients in the intervention group were included in the analysis. In the control group, 23 (9.9%) developed SSI, compared with 13 (5.6%) in the intervention group. After adjustment for potential confounding factors, women in the postintervention period experienced a statistically significant reduction in SSI rates (adjusted odds ratio =0.45, 95% CI = 0.22-0.95); P = .04). Conclusion. Implementation of a hospital protocol of NPT following cesarean delivery in obese women resulted in reduced incidence of postoperative SSI. This study suggests that using NPT after cesarean delivery in women with a BMI ≥40 kg/m2 is an efficacious method to reduce incidence of postoperative wound infections.
Inter-organizational relations among schools: Collaboration rather than competition
Authors: de Lima Jorge Ávila , Dâmaso Marlene
Published: November 2017

This paper reports the findings of an exploratory study that analyzed relations among schools located in a Portuguese municipality where these organizations were officially authorized to compete with one another for students. The data were collected through semi-structured interviews with school leaders. The findings show that despite the formal possibility of inter-school competition within an educational market framework, there was no significant competition among the schools, and that their leaders managed their relations with other organizations in accordance with collaborative principles. The paper addresses some of the factors that may account for this and which provide a useful illustration of the specific nature of local educational environments, within the context of the global introduction of market mechanisms in education systems.
Civilised Tribalism: Burning Man, Event-Tribes and Maker Culture
Authors: St John Graham
Published: November 2017

Otherwise known as Black Rock City, Burning Man is an artistic event, that, mounted annually in Nevada’s Black Rock Desert, has become the inspiration for a global cultural movement. While it has been the subject of considerable attention from ethnographers and sociologists, Burning Man has persistently resisted classification. In this article, I undertake a tentative approach to Burning Man via a concept integral to Maffesoli’s postmodern social philosophy popular within Anglophone sociology: the neo-tribe. Ethnographic attention to Burning Man illustrates spectacular aspects of neo-tribalism. It is cyclical, immediate, sensual, enchanted, collaborative and offers multiple sites of belonging for participants, many of whom will self-identify as ‘tribal’ or ‘neo-tribal’. And yet Burning Man is also demonstrative of an optimising modernist ‘project’ complicating, if not incongruent with, postmodern tribalism. With Black Rock City theme camps, art projects and build teams echoing a design-orientated maker culture, and an organisation – the Burning Man Project – dedicated to propagating and scaling (making) the ethical, civic and progressive dimensions of this culture, this article demonstrates the paradoxical proclivities of Burning Man’s tribal character. The objective of the article is to forge a fuller understanding of Burning Man and other ‘transformational’ events illustrative of an alternative tribalism, and to explore ways the phenomenon both approximates and deviates from Maffesoli’s thesis.
Too much parental cooperation? Parent–teacher cooperation and how it influences professional responsibility among Danish schoolteachers
Authors: Dahl Kari Kragh Blume
Published: November 2017

Parental participation is a fundamental principle of the Danish folkeskole (for children aged 6–16), yet this article explores how too much parental cooperation influences the relationship of teachers to their professional responsibility. The majority of research on parent–teacher cooperation has focused on parents’ opportunities to participate in school life, but little is known about what teachers think about such collaboration, and how imbalances in power and authority in parent–teacher cooperation influence teachers’ professionalism. The use of reflexive autoethnographic accounts, participant observation and document analysis during a four-year period in one school provided emic insight into the, often invisible, social processes of power. Semi-structured interviews with teachers in a second school were also conducted. Drawing on a body of interrelated work focusing on Bourdieu, situated learning theory and literature about professional studies, the findings suggest that parent–teacher communities can be understood as stratified fields which provide different and complex spaces for exerting power and domination. Although power in these communities is constantly negotiated, professional responsibility may be lost when parents occupy central positions in parent–teacher collaborations.
Youth Baseball Pitching Mechanics: A Systematic Review
Authors: Thompson Samuel F. , Guess Trent M. , Plackis Andreas C. , Sherman Seth L. , Gray Aaron D.
Published: November 2017

Context:

Pitching injuries in youth baseball are increasing in incidence. Poor pitching mechanics in young throwers have not been sufficiently evaluated due to the lack of a basic biomechanical understanding of the “normal” youth pitching motion.

Objective:

To provide a greater understanding of the kinetics and kinematics of the youth baseball pitching motion.

Data Sources:

PubMed, MEDLINE, and SPORTDiscus databases were searched from database inception through February 2017.

Study Selection:

A total of 10 biomechanical studies describing youth pitching mechanics were included.

Study Design:

Systematic review.

Level of Evidence:

Level 3.

Data Extraction:

Manual extraction and compilation of demographic, methodology, kinetic, and kinematic variables from the included studies were completed.

Results:

In studies of healthy youth baseball pitchers, progressive external rotation of the shoulder occurs throughout the start of the pitching motion, reaching a maximum of 166° to 178.2°, before internally rotating throughout the remainder of the cycle, reaching a minimum of 13.2° to 17°. Elbow valgus torque reaches the highest level (18 ± 4 N·m) just prior to maximum shoulder external rotation and decreases throughout the remainder of the pitch cycle. Stride length is 66% to 85% of pitcher height. In comparison with a fastball, a curveball demonstrates less elbow varus torque (31.6 ± 15.3 vs 34.8 ± 15.4 N·m).

Conclusion:

Multiple studies show that maximum elbow valgus torque occurs just prior to maximum shoulder external rotation. Forces on the elbow and shoulder are greater for the fastball than the curveball.
The role of selective serotonin reuptake inhibitors in preventing relapse of major depressive disorder
Authors: Clevenger Steven S. , Malhotra Devvrat , Dang Jonathan , Vanle Brigitte , IsHak Waguih William
Published: November 2017

The objective of this review was to evaluate the efficacy of selective serotonin reuptake inhibitors (SSRIs) and SSRIs compared with other treatment modalities in preventing relapse after an episode of major depressive disorder (MDD). An Ovid MEDLINE and PsycINFO search (from 1987 to August 2017) was conducted using the following terms: selective serotonin reuptake inhibitors, antidepressants, depression, prevention, prophylaxis, relapse and MDD. Using predefined criteria, two authors independently selected and reached consensus on the included studies. Sixteen articles met the criteria: 10 compared the relapse rate of selective SSRIs with placebo or other SSRIs; one discussed the effectiveness of SSRIs plus psychotherapy, two compared SSRI versus tricyclic antidepressants (TCAs), two were mainly composed of TCAs plus psychotherapy, and one compared SSRIs and serotonin norepinephrine reuptake inhibitors (SNRIs). According to the included studies, the relapse risk in adults was lower when SSRIs were combined with psychotherapy. Results comparing SSRIs and SNRIs were inconclusive. TCAs may be equally as effective as SSRIs. Atypical antidepressants (mirtazapine and St John’s Wort) had no significant difference in efficacy and remission rates compared with SSRIs. Escitalopram appeared to fare better in efficacy than other SSRIs, owing to a higher prophylactic efficacy and lower side effects; however, according to the current data, this difference was not significant. To conclude, this review provides evidence that continuing SSRIs for 1 year reduces risk of MDD and relapse. Furthermore, the combination of SSRIs and cognitive behavioural therapy may effectively reduce relapse. Escitalopram appeared to yield better results and fewer side effects than did other SSRIs or SNRIs. The effectiveness in reducing relapse of SSRIs was similar to that of TCAs and atypical antidepressants.
Operating room central serous chorioretinopathy
Authors: Mansour Ahmad M , Hamam Rola
Published: November 2017

Objectives:

The operating room is a place of surgical intervention with its accompanying bodily and cognitive strain on the performers. Stress in the operating room may lead to the onset of central serous chorioretinopathy as reported hereby in a retina surgeon and is labeled as operating room central serous chorioretinopathy.

Methods:

The same operator performed the optical coherence tomography scans on one retina surgeon. A masked observer estimated the maximal height of the subretinal fluid.

Results:

Central serous chorioretinopathy recurred four times over a 1-year period 1 -2 days after a stressful day in the operating room, especially when cases were done under topical or subtenon anesthesia for cataract surgery, vitreous surgery or combined surgeries with complex ocular and medical problems and inability for anesthesia team to intervene. Stress management allowed resolution of subretinal fluid between 3 and 4 weeks. Adopting this strategy, no further attacks were documented by optical coherence tomography for 5 years.

Conclusions:

(1) This is one of a few optical coherence tomography documentation of resolution of central serous chorioretinopathy within 3-4 weeks of its occurrence and its recurrence induced by stress in the operating room; (2) Unassisted topical anesthesia required in patients with complex medical and ocular problems causes more cognitive stress than when surgery is carried under assisted local or general anesthesia (partly due to unexpected ocular or bodily movements); and (3) the available evidence suggests that those overcommitted surgeons (type A personality) may very well be most susceptible to burnout and central serous chorioretinopathy.
Boycotts, buycotts, and political consumerism in America
Authors: Endres Kyle , Panagopoulos Costas
Published: November 2017

Anecdotal and experimental evidence suggests that at least some consumers change their purchasing behavior in response to the values, reputations, and political activity of corporations. Using two nationally-representative surveys and a third survey of registered voters, we find Americans’ engagement in boycotts and/or buycotts for political or social reasons to be widespread. Social media activity, political knowledge, ideological intensity, and an interest in politics are significantly associated with political-consumer behavior. Among partisans, we find both instrumental and expressive partisanship to be significant predictors of political consumerism.
Assessing the stigma content of urinary incontinence intervention outcome measures
Authors: Southall Kenneth , Tuazon Joshua R , Djokhdem Abdul H , van den Heuvel Eleanor A , Wittich Walter , Jutai Jeffrey W
Published: November 2017

The goal of this narrative review is to evaluate the efficacy of available questionnaires for assessing the outcomes of “continence difficulty” interventions and to assess the selected questionnaires concerning aspects of stigmatization. The literature was searched for research related to urinary incontinence, as well as questionnaires and rating scale outcome measurement tools. The following sources were searched: Cochrane Library, EMBASE, Medline, and PubMed. The following keywords were used separately or in combination: “Urinary incontinence,” “therapy,” ”treatment outcome,” “patient satisfaction,” “quality of life,” “systematic reviews,” “aged 65+ years,” and “questionnaire.” The search yielded 194 references, of which 11 questionnaires fit the inclusion criteria; 6 of the 11 questionnaires did not have any stigma content and the content regarding stigma that was identified in the other five was very limited. A representative model of how stigma impacts continence difficulty interventions was proposed. While the 11 incontinence specific measurement tools that were assessed were well researched and designed specifically to measure the outcomes of incontinence interventions, they have not been used consistently or extensively and none of the measures thoroughly assess stigma. Further studies are required to examine how the stigma associated with continence difficulty impacts upon health care interventions.
Food Network Resilience Against Natural Disasters: A Conceptual Framework
Authors: Umar Muhammad , Wilson Mark , Heyl Jeff
Published: November 2017

We propose a conceptual framework that highlights the importance of logistics, collaboration, sourcing, and knowledge management in achieving supply chain resilience. This framework is developed after extensive literature review of relief supply chains, supply chain resilience, and disaster management disciplines. This review reveals that our understanding of supply chain resilience for food supply chains in a disaster scenario is still in its infancy. We note the lack of any consolidated framework or generalized theory in this area. Different topics related to resilience are usually discussed in isolation; hence, this research has attempted to combine different concepts drawn from various areas into one framework. We postulate that food supply chains can develop certain capabilities such as agility, adaptability, and alignment within the four supply chain domains of logistics, collaboration, sourcing, and knowledge management. Supply chain orientation and risk management culture plays the facilitating role in this framework. Adopting this systems approach would allow greater insights into how food supply chains can become more resilient to natural disasters.
Role of Green Procurement in Driving Sustainable Innovation in Supplier Networks: Some Exploratory Empirical Results

Strategic green procurement is key to success in any manufacturing business under the current Volatile, Uncertain, Complex and Ambiguous (VUCA) environment. There are tremendous pressures from government institutions, pressure groups and other institutions on every manufacturing unit aiming to divert attention of the organization toward environmental, social and economic dimensions while making any sourcing decisions. Therefore, it is imperative to proactively strategize and develop a robust supplier network capable of innovating newer products and services which is ultimately sustainable for the business. However, as previously mentioned such actions are influenced by institutional pressures, culture in the organization and green procurement strategy. The aim of this article is to develop a con-ceptual framework considering institutional pressures, organization culture, and green procurement, and further test it using primary survey data collected from South African manufacturing units. Finally, we argue that institutional pressures directly influence green procurement practices and further green procurement practices enhance sustainable innovation performance in supplier networks. The study concludes with some food for thought to the research community.
The Risky Path to a Followership Identity: From Abstract Concept to Situated Reality
Authors: Larsson Magnus , Nielsen Mie Femø
Published: November 2017

Followership research has increased recently, but little attention has been paid to the complexities and challenges of creating a followership identity. Researchers typically portray followership as a safe alternative to leadership identity, but we challenge this assumption by using naturally occurring workplace interactions to identify active contributions as well as risks associated with a follower identity. In this study, we use conversation analysis to examine how people collaboratively construct identities, and how identity development shapes and organizes interactions between people. The findings reveal the risks of misidentifying the task at hand, of being too authoritative, and of claiming too much knowledge. Also, our analyses highlight that leader and follower roles remain abstract in workplace interactions and, instead, people focus more on negotiated, task-oriented, practical identities.
Evaluation of a Method for Determining Binaural Sensitivity to Temporal Fine Structure (TFS-AF Test) for Older Listeners With Normal and Impaired Low-Frequency Hearing
Authors: Füllgrabe Christian , Moore Brian C. J.
Published: November 2017

The ability to process binaural temporal fine structure (TFS) information was assessed using the TFS-AF test (where AF stands for adaptive frequency) for 26 listeners aged 60 years or more with normal or elevated low-frequency audiometric thresholds. The test estimates the highest frequency at which a fixed interaural phase difference (IPD) of ϕ (varied here between 30° and 180°) can be discriminated from an IPD of 0°, with higher thresholds indicating better performance. A sensation level of 30 dB was used. All listeners were able to perform the task reliably, giving thresholds well above the lowest allowed frequency of 30 Hz. The duration of a run averaged 5 min. Repeated testing of the normal-hearing listeners showed no significant practice effects. Thresholds varied markedly across listeners, but their ranking was fairly consistent across values of ϕ. Thresholds decreased (worsened) with decreasing ϕ and were lower than for a group of young listeners tested in an earlier study. There were weak to moderate, negative correlations between TFS-AF thresholds and audiometric thresholds at low frequencies (125–1000 Hz) but not at high frequencies (4000–8000 Hz). In conclusion, the TFS-AF test yielded a graded measure of binaural TFS sensitivity for all listeners. This contrasts with the TFS-LF (low-frequency) test, which measures the smallest detectable shift in IPD for a fixed frequency. The absence of practice effects and a reasonably short administration time make the TFS-AF test a good candidate for the assessment of sensitivity to changes in binaural TFS for older listeners without or with hearing loss.

Here we report the methods and output of a workshop examining possible futures of speech and hearing science out to 2030. Using a design thinking approach, a range of human-centered problems in communication were identified that could provide the motivation for a wide range of research. Nine main research programs were distilled and are summarized: (a) measuring brain and other physiological parameters, (b) auditory and multimodal displays of information, (c) auditory scene analysis, (d) enabling and understanding shared auditory virtual spaces, (e) holistic approaches to health management and hearing impairment, (f) universal access to evolving and individualized technologies, (g) biological intervention for hearing dysfunction, (h) understanding the psychosocial interactions with technology and other humans as mediated by technology, and (i) the impact of changing models of security and privacy. The design thinking approach attempted to link the judged level of importance of different research areas to the “end in mind” through empathy for the real-life problems embodied in the personas created during the workshop.
Aging Partners Managing Chronic Illness Together: Introducing the Content Collection
Authors: Nowakowski Alexandra C. H. , Sumerau J. E.
Published: November 2017

Prior literature on illness management within intimate relationships demonstrates a variety of benefits from supportive partnership. Indeed, much of the earliest research in this field engaged older adults with and without chronic conditions. However, this pioneering literature gave little consideration to relationships in which multiple partners were coping with chronic illness. By contrast, the majority of published manuscripts presented a “sick partner/well partner” model in which caregiving flowed only in one direction. Yet this idea makes little sense in the context of contemporaneous data on population aging and health as a majority of older adults now live with at least one chronic condition. Scholars still have not delved explicitly into the experiences of the vast population of older relationship partners who are managing chronic conditions simultaneously. We thus welcome Gerontology and Geriatric Medicine readers to this special content collection on Aging Partners Managing Chronic Illness Together.
Interfaith Marriages and Negotiated Spaces
Authors: Verma Shweta , Sukhramani Neelam
Published: November 2017

Discourse on interfaith marriages in India at present involves diverse narratives ranging from opposition and resistance to acceptance. These alliances deserve greater focus in terms of their uniqueness, challenges as well as everyday negotiations that form part of their lives. Based on narratives of respondents from Dhanak, an organisation of inter-caste and interfaith couples, this article presents some domains of their lives and spaces being negotiated by them within their families. These domains include the issue of conversion, protecting identity, celebration of diversity and socialisation of children, perceptions of themselves vis-à-vis other families and parental outlook towards the alliance.
Christianity 2018: More African Christians and Counting Martyrs

Published: November 2017

This article features five statistical tables with 2018 figures for many aspects of global Christianity, from membership to finance to martyrdom. Over the last 1,000 years, Europe had more Christians than any other continent. By 2018 Africa had the most Christians: 599 million, vs. 597 million in Latin America and 550 million in Europe. At the same time, Christianity continues to decline in the Middle East, falling from 13.6 percent of the population in 1900 to less than 4 percent today. In 1800 Christians and Muslims together represented only 33 percent of the world’s population; by 2018 they represented 57 percent, increasing to 64 percent by 2050.
