Background:

The prognostic impact of coronary microvascular dysfunction after percutaneous coronary intervention (PCI) remains unclear in patients with stable coronary artery disease. This study sought to investigate the prognostic value of microvascular function measured immediately after PCI in patients with stable coronary artery disease.

Methods:

We enrolled 572 patients with stable coronary artery disease who underwent PCI and elective measurement of the index of microcirculatory resistance (IMR) immediately after PCI from 8 centers in 4 countries. Impaired microvascular function was defined as IMR≥25 (high IMR). Major adverse cardiac events, including death, myocardial infarction (MI) and target vessel revascularization, were evaluated.

Results:

During a median follow-up duration of 4.0 years, the cumulative major adverse cardiac events rate was significantly higher in the high IMR group (n=66/148) compared with the low IMR group (n=128/424; hazard ratio [HR], 1.56; 95% CI, 1.16−2.105;
P
=0.001), primarily due to a higher rate of periprocedural MI (HR, 1.59; 95% CI, 1.11−2.28;
P
=0.004) but also due to higher rates of mortality (HR, 1.59; 95% CI, 0.76−3.35;
P
=0.22), spontaneous MI (HR, 2.10; 95% CI, 0.67−6.63;
P
=0.20) and target vessel revascularization (HR, 1.40; 95% CI, 0.77−2.54;
P
=0.27). Cumulative risk for death, spontaneous MI, and target vessel revascularization was higher in the high IMR group (HR, 1.55; 95% CI, 0.99−2.43;
P
=0.056), as was death and spontaneous MI alone (HR, 1.79; 95% CI, 0.96−3.36;
P
=0.065). On multivariable analysis, high IMR post-PCI was an independent predictor of major adverse cardiac events.

Conclusions:

IMR measured immediately after PCI predicts adverse events in patients with stable coronary artery disease.

The wounds of childhood: Early trauma subtypes, salience and hyperarousal in a sample of adult psychiatric patients
Authors: Muscatello Maria Rosaria Anna , Rizzo Amelia , Celebre Laura , Mento Carmela , Pandolfo Gianluca , Cedro Clemente , Battaglia Fortunato , Zoccali Rocco Antonio , Bruno Antonio
Published: September 2019

Background:

The relationship between early trauma, hyperarousal and aberrant salience has been investigated exclusively in specific clinical samples, such as post-traumatic stress disorder (PTSD) and psychotic patients, and the results suggest that both dimensions are trauma-induced events, which may lead to the later onset, or increase the vulnerability to psychiatric disorders. The aim of the present research was to evaluate the possible relationships among early childhood trauma subtypes and the dimensions of hyperarousal and aberrant salience in an adult sample of psychiatric patients.

Materials and Methods:

One-hundred psychiatric adult outpatients were assessed by Early Trauma Inventory Self Report-Short Form (ETISR-SF), Aberrant Salience Inventory (ASI) and Hyperarousal Scale (H-Scale). A linear regression analysis was performed in order to investigate which early traumatic events were a predictor of the aberrant salience and the hyperarousal.

Results:

Regression analysis indicated that only ETISR-SF ‘Emotional abuse’ was the unique predictor of ASI ‘Total score’ ( p < .0001) and H-Scale ‘Total score’ ( p = .031), whereas other ETISR-SF variables did not give a significant additional contribution to the prediction of aberrant salience and the hyperarousal dimension.

Conclusions:

These findings support the role of emotional abuse as predictor of hyperarousal, a basic dimension associated with general vulnerability to mental illness. The awareness of the psychiatric consequences of early childhood trauma leads us to consider the need for better identification of children at risk, to develop effective interventions for the protection of minors from violent and/or inappropriate behaviors and to promote the development of protective resilience factors against re-victimization.
Beyond Neo-liberalism: Analyzing the ‘Post-Developmental State’ in South Korea
Authors: Uttam Jitendra
Published: September 2019

After painful reform and restructuring of post-1997 financial crisis, many scholars equated South Korea’s ‘post-developmental state’ with neo-liberal state. However, in doing so, they ignored South Korea’s lasting legacy of interventionist ‘developmental state’ that led nation’s miraculous transformation from a poor agrarian society to a prosperous industrial economy. This article stresses that South Korea indeed tried to adopt some of the policy prescriptions suggested by neo-liberal ideas but moving beyond the dictates of neo-liberalism it also strengthened state capacity to augment non-market mechanisms.

The article argues that South Korea’s post-developmental state moved into two non-market spheres; First, by tilting towards becoming a ‘techno-scientific state’ and second, it attempted to reimaging South Korea by leaning to develop into a ‘Brand state’. Both non-market initiatives moved South Korea ‘beyond neo-liberalism’ and invoked its ‘statist developmental’ past guided by Keynesian economics. South Korea’s reach to incorporate market and non-market dictates has invited terms such as ‘liberal developmentalism’, a hybrid system where state used its enhanced capacity to improve the efficiency of market system.
µ-Opioid Activity in Chronic TMD Pain Is Associated with COMT Polymorphism

Published: September 2019

Clinicians have the dilemma of prescribing opioid or nonopioid analgesics to chronic pain patients; however, the impact of pain on our endogenous µ-opioid system and how our genetic profile (specifically catechol-O-methyltransferase [ COMT] polymorphisms) impacts its activation are currently unknown. Twelve chronic temporomandibular disorder (TMD) patients and 12 healthy controls (HCs) were scanned using positron emission tomography (PET) with [11C]carfentanil, a selective radioligand for µ-opioid receptors (µORs). The first 45 min of each PET measured the µOR nondisplaceable binding potential (BPND) at resting state, and the last 45 min consisted of a 20-min masseteric pain challenge with an injection of 5% hypertonic saline. Participants were also genotyped for different COMT alleles. There were no group differences in µOR BPND at resting state (early phase). However, during the masseteric pain challenge (late phase), TMD patients exhibited significant reductions in µOR BPND (decreased [11C]carfentanil binding) in the contralateral parahippocampus ( P = 0.002) compared to HCs. The µOR BPND was also significantly lower in TMD patients with longer pain chronicity ( P < 0.001). When considering COMT genotype and chronic pain suffering, TMD patients with the COMT 158Met substitution had higher pain sensitivity and longer pain chronicity with a 5-y threshold for µOR BPND changes to occur in the parahippocampus. Together, the TMD diagnosis, COMT 158Met substitution, and pain chronicity explained 52% of µOR BPND variance in the parahippocampus (cumulative R2 = 52%, P < 0.003, and HC vs. TMD Cohen’s effect size d = 1.33 SD). There is strong evidence of dysregulation of our main analgesic and limbic systems in chronic TMD pain. The data also support precision medicine by helping identify TMD patients who may be more susceptible to chronic pain sensitivity and opioid dysfunction based on their genetic profile.

Religiosity and economic attitudes in post-communist Central Europe: Some additional evidence
Authors: Minarik Pavol
Published: September 2019

Religion and religiosity are rarely the main focus of economic research; although, some studies have already shown the importance of religion for economic development. Previous research has also provided some evidence that religiosity matters in the process of formation of economic attitudes. Economic attitudes and culture in general affect social institutions and economic development, especially in the periods of institutional change. This article provides some additional evidence that religiosity has had an impact on economic attitudes in post-communist countries. Thus, religion shall be taken seriously as an explanatory variable when it comes to evaluation of transition process and its outcomes.
Discussing the de-secular online: Legitimization and resistance to the political engagement of the Moscow Patriarchate in the Russian blogosphere
Authors: Grishaeva Ekaterina
Published: September 2019

To date, there has been an abundance of studies that either cover the interaction of religion and secular institutions or focus on how religious actors seek to reshape institutional differentiation by protecting a ‘sacred life-world’. Nevertheless, the reaction of religious communities to de-secular changes has rarely been studied. This article fills this lacuna by analyzing the debates of Orthodox bloggers over the de-secular strategy of the Moscow Patriarchate (MP). This research draws on Castells’ concept of resisting and legitimizing identities in order to map out the ideological positions that Orthodox bloggers take when arguing for or against de-secularization. The analysis of the blogs reveals that the difference in the way in which the MP’s de-secular agenda is assessed has played a key role in engendering a split within the online Orthodox community along attitudes towards the church’s religious and political power.
The gender gap in religiosity over time in Italy: Are men and women really becoming more similar?
Authors: Palmisano Stefania , Todesco Lorenzo
Published: September 2019

Many studies have shown that women are more religious than men, a difference long accepted as an established fact in the sociology of religion. But some recent research has revealed that this difference is not ‘universal’, varying in space and time. However, only a few scholars have focused on religiosity gender-gap trends over time, either on the theoretical or empirical levels. The aim of this article is to help fill this gap by analysing the progress of gender differences in religiosity from 1981 to 2009 in Italy, an interesting cultural context because of the gradual penetration of secularisation and the high level of gender inequality. Our empirical analysis is based on a longitudinal approach, using data from the European Values Study. The findings show that the gender gap in Italy was quite stable in regard to many aspects of religiosity, with three noteworthy exceptions: the gender gap decreased in beliefs, in intergenerational transmission of faith and in adherence to the Church’s doctrines on prostitution, abortion, divorce, euthanasia, suicide and adultery. Contrary to expectations, in most cases this narrowing came about because of an increase in men’s religiosity, not a decrease in women’s.
Rethinking Person-Centeredness: Contestations of Disability, Care, and Culture at the Social Service Application Interface
Authors: Campeau Kari
Published: September 2019

This article examines how normative assumptions about disability, family, and care perpetuate barriers to social services in cross-cultural contexts. It reports on an 8-month case study of how a county-sponsored, person-centered disability grant targeted but failed to meet the needs of Somali applicants. I identify four impasses that alienated applicants and demonstrated the grant's process relied on culture norms, including medical definitions of disability, institutional expertise, and normalization of self-sufficiency. I develop three recommendations for future technical communication and policy interventions. This study offers insights into how person-centered initiatives can engage the contexts and expertise of diverse users within institutional structures.
Using dates as contextual information for personalised cultural heritage experiences
Authors: Dahroug Ahmed , Vlachidis Andreas , Liapis Antonios , Bikakis Antonis , López-Nores Martín , Sacco Owen , Pazos-Arias José Juan
Published: September 2019

We present semantics-based mechanisms that aim to promote reflection on cultural heritage by means of dates (historical events or annual commemorations), owing to their connections to a collection of items and to the visitors’ interests. We argue that links to specific dates can trigger curiosity, increase retention and guide visitors around the venue following new appealing narratives in subsequent visits. The proposal has been evaluated in a pilot study on the collection of the Archaeological Museum of Tripoli (Greece), for which a team of humanities experts wrote a set of diverse narratives about the exhibits. A year-round calendar was crafted so that certain narratives would be more or less relevant on any given day. Expanding on this calendar, personalised recommendations can be made by sorting out those relevant narratives according to personal events and interests recorded in the profiles of the target users. Evaluation of the associations by experts and potential museum visitors shows that the proposed approach can discover meaningful connections, while many others that are more incidental can still contribute to the intended cognitive phenomena.
Low-Carbon Transition as Vehicle of New Inequalities? Risk-Class, the Chinese Middle-Class and the Moral Economy of Misrecognition
Authors: Curran Dean , Tyfield David
Published: September 2019

Low-carbon innovation is usually depicted as an exemplar of pursuit of the common good, in both mainstream policy discussion and the emerging orthodoxy of transition studies. Yet it may emerge as a key means of intensifying inequality. We analyse low-carbon innovation as a social and political process through the prism of differential risk-classes, focusing on the pivotal global case of emergence of the Chinese middle-class in seaboard megacities, especially regarding the profound challenges of urban e-mobility transition. This approach shows emergence of this still-forming sociopolitical grouping as tightly and complementarily coupled with the assembling of innovations that meaningfully tackle global risks, such as climate change, while also intensifying existing inequalities. Misrecognition of the duality of low-carbon innovations as both moral technologies and as relatively expensive consumer products has the potentiality to be a key mechanism of this process, thereby serving to reproduce, constitute and legitimize inequalities in novel and unexpected ways.
The Creativity of Digital (Audiovisual) Archives: A Dialogue Between Media Archaeology and Cultural Semiotics
Authors: Ibrus Indrek , Ojamaa Maarja
Published: September 2019

Much writing on, first, analogue and, later, digital archives has focused on related power-dynamics and the structuring effects of archives and their technologies on discursive freedom and cultural dynamics. In recent years, however, work within the media archaeology domain, especially by Wolfgang Ernst, has addressed how the specific materialities of digital archives, and the nature of their algorithms and particular functions, could be seen to facilitate dynamics in cultures. This article sets this work in dialogue with the cultural semiotics of Juri Lotman, whose late work focused on how communicative processes between and within different subsystems of culture facilitate their dynamic change and the production of new forms and cultural systems. The article suggests further interdisciplinary dialogue between media archaeology and cultural semiotics in order to understand the role of archives in facilitating communicative processes and interlinking in culture and the emergence of novelties – that is, for understanding the ‘creativity’ of archives.
Case–control evaluation of the impact of below 20 mmHg elastic compression stockings on lower limb volume serial variations in standardized flights
Authors: Gianesini Sergio , Mosti Giovanni , Raffetto Joseph D , Maietti Elisa , Chi Yung-Wei , Tangerini Luca , Menegatti Erica
Published: September 2019

Background

Graduated compression stocking (GCS) use during flights demonstrated to positively impact leg oedema. Nevertheless, these data were collected in a single flight, mainly at the ankle, and using greater than 20 mmHg GCS. This investigation reports data from 16 flights in which the same passenger’s leg circumferences variation were assessed wearing non-graduated ankle-sock or a below-knee 15–20 mmHg GCS.

Methods

The limb was divided by the circumferences in eight sectors, every 4 cm, labelled from 1 to 8, starting from the ankle up. The assessment was done at the take-off and after a 4-h flight time, for a total of 16 flights. The subject used non-graduated ankle socks (elastic band at 4 cm from B-point) during the outgoing flight and below-knee GCS (15–20 mmHg) during the return flight. Interface pressure was assessed at the ankle point of minimum girth (B) and ascending proximally every 4 cm (B+cm) for the GCS, and at B and at the elastic band level (B + 4 cm) for the sock.

Results

GCS interface pressure was 13.3 ± 2.5 mmHg in B and 18.1 ± 2.4 mmHg in B + 4 cm. The sock interface pressure was 3.1 ± 0.7 mmHg in B and 8.1 ± 0.9 mmHg at the band level (B + 4 cm). Socks led to a significant total volume increase (117.3 ± 25.8 mL; 5.2% ±1.1%; P < 0.0001). GCS led to a non-significant total volume decrease (–3.1 ± 14.4 mL; –0.1 ± 0.6%; P = 0.3964) and did not allow for volume increase. The different sectors showed a heterogeneous volume variation, not following a precisely graduated or progressive compression profile.

Conclusions

Leg oedema following a 4-h flight is controlled by <20 mmHg GCS. Leg fluids, with and without GCS, are mobilized in a non-graduated profile from the ankle to the knee after prolonged sitting on a plane.
Which pressure of adjustable compression wrap system is necessary to reduce deep vein cross section area in post-thrombotic patients? A proof-of-concept study
Authors: Szary Cezary , Wilczko Justyna , Grzela Tomasz , Partsch Hugo
Published: September 2019

Objective

The conservative treatment of post-thrombotic syndrome includes application of compression on the affected extremity. However, the type and the level of compression required to manage post-thrombotic syndrome are still unclear. The aim of our proof-of-concept study was to assess the compression required to reduce cross section area of post-thrombotic deep veins in 22 patients with post-thrombotic syndrome.

Methods

The circumference and cross section area of posterior tibial veins and saphenous vein trunk were assessed on mid-calf level using 3T magnetic resonance scanner, at increasing compression (0, 30, 40, and 50 mmHg), provided by a novel adjustable Velcro compression wrap, the CircAid JuxtaLite®.

Results

A significant reduction of baseline vein cross section area in post-thrombotic syndrome patients in the lying position required compression of at least 30 mmHg for posterior tibial veins, and at least 40 mmHg for the saphenous trunk. Apart from morphological changes of the compressed veins, we observed extinction of T2w signal at compression above 40 mmHg, which corresponded to accelerated blood flow in the veins, and therefore may be considered as a hemodynamic marker of compression effectiveness.

Conclusion

CircAid adjusted to compression level ≥40 mmHg accelerates blood flow in affected deep veins, thus it may facilitate post-thrombotic syndrome management.
‘Some men deeply hate women, and express that hatred freely’: Examining victims’ experiences and perceptions of gendered hate crime
Authors: Mason-Bish Hannah , Duggan Marian
Published: September 2019

Extensive debate about the place of gender within the hate-crime policy domain has been fuelled by national victimisation surveys indicating people’s experiences of ‘gender hate crime’ coupled with Nottinghamshire Police’s decision to begin categorising misogynistic street harassment as a form of hate crime. Drawing on the results of an online survey of 85 respondents, this article explores people’s experiences of gender-related victimisation as ‘hate crimes’. The analysis demonstrates how participants relate their experiences to the concept of hate crime, their perceptions on punishment and reporting to the police, and also wider impacts on their recovery processes. This paper provides a timely contribution towards current debates around using the existing hate-crime model for addressing crimes motivated by gender hostility.
Comparison of ramosetron and ondansetron for the prevention of postoperative nausea and vomiting in patients undergoing laparoscopic surgery: a meta-analysis of randomized controlled trials
Authors: Li Yiping , Deng Ruiming , Zhou Juan , Chen Yuan , Ouyang Aiping
Published: September 2019

Objective

We conducted a systematic literature search and meta-analysis to identify randomized controlled trials (RCTs) comparing the efficacy and safety of ramosetron versus ondansetron for the prevention of postoperative nausea and vomiting (PONV; PON and POV, respectively) in patients undergoing laparoscopic surgery.

Methods

The electronic databases PubMed, EMBASE, Web of Science, and Cochrane Library were searched up to March 2019 to identify relevant studies.

Results

The final pooled analysis included 6 RCTs and revealed that postoperative treatment with ramosetron at 24 to 48 hours after surgery significantly reduced the incidence of PON and POV relative to treatment with ondansetron. In a subgroup analysis, ramosetron 0.3 mg tended to reduce PON (0–2 hours) and POV (24–48 hours) more effectively than ondansetron 4 mg. However, no statistical difference was observed between ramosetron 0.3 mg and ondansetron 8 mg in terms of the reduction of PON or POV during any time interval within the first 48 hours after surgery.

Conclusions

Our results indicate that ramosetron 0.3 mg is superior to ondansetron 4 mg and comparable to ondansetron 8 mg for PONV prophylaxis after laparoscopic surgery.
Engaging in open innovation: The mediating role of work engagement in the relationship between transformational and transactional leadership and the quality of the open innovation process as perceived by employees
Authors: Edelbroek Robin , Peters Pascale , Blomme Robert Jan
Published: September 2019

This study contributes to the literature on open innovation by addressing the scarcity of individual-level literature and insight into the human side of open innovation. Specifically, it examines the relationships between transactional and transformational leadership on the one hand and the quality of the open innovation process as perceived by employees on the other, and whether these relationships are (partly) mediated by employees’ work engagement. Hypotheses were tested using partial least squares structural equation modelling analysis on a bootstrapped sample ( n = 173) of employees in various organizations. Transformational leadership was shown to have a positive direct and indirect relationship with open innovation, partly mediated by engagement. Additionally, this study provides guidance for managers on how to enhance the employee’s perspective on the open innovation process through transformational leadership behaviour and work engagement.
With other people’s money: Campaign financing as an agency problem
Authors: Gama Marina Amado Bahia , Galilea Gisele Walczak , Bandeira-de-Mello Rodrigo , Marcon Rosilene
Published: September 2019

Agency theory explanations for corporate political activity assume that managers distort resource allocation to invest in political connections to pursue personal benefits. While distorted resource allocations yield poor earning quality, we expect that companies with efficient governance may curb this opportunistic behavior. We used matching procedures to identify the effects of financing political campaigns on the earning quality of the firm. We assembled an original panel of listed firms in Brazil from 1998 to 2013. We found that firms that donated to electoral campaigns had a lower earning quality than nondonor firms. Firms with superior corporate governance instruments were able to reduce the harmful effects on earning quality. These results support the tenets of agency theory in explaining why firms engage in politics.
A novel serum: Electrophoresis method to prepare acellular corneal matrix as an artificial corneal scaffold
Authors: Li Qing , Xie Cuicui , Wang Hongmei , Zhang Fenghua , Mu Lanlan
Published: September 2019

Introduction:

The aim of this study was to develop a novel decellularization method in order to obtain an ideal scaffold with good biocompatibility.

Methods:

The porcine corneas were treated with human serum for 5 days or serum-electrophoresis respectively. The electrophoresis (100 V/cm) was performed in sterilized buffer containing 40-mM tris base, 18-mM glacial acetic acid, and antibiotics for 1 h at 4°C. The properties of artificial corneal scaffolds were characterized by morphological and histological examinations. The biocompatibility and biological safety were examined by subcutaneous implant test and lamellar keratoplasty.

Results and conclusions:

The transparency and appearance of serum-electrophoresis acellular porcine corneal matrix were better than serum acellular porcine corneal matrix. DNA and α-gal in serum-electrophoresis acellular porcine corneal matrix were more efficiently removed than those in serum acellular porcine corneal matrix (p < 0.05). The subcutaneous and corneal implantation experiments showed serum-electrophoresis acellular porcine corneal matrix had better biocompatibility compared to serum acellular porcine corneal matrix (p < 0.01). This novel serum-electrophoresis decellularization method may be valuable for preparation of xenogenic corneal tissue for clinical application.
The Northfield Experiments—a reappraisal 70 Years On
Authors: Coombe Paul
Published: September 2019

More than 70 years ago during the Second World War, what became known as the Northfield Experiments began in a southern suburb of Birmingham, England. By 1946 these experiments had ceased and the major participants had journeyed in different directions but carried with them new ideas, particularly in relation to group psychotherapy and more generally applied psychoanalysis. John Rickman, Wilfred Bion, Tom Main, Sigmund Foulkes, Harold Bridger, Patrick de Maré and others at the end of the war dispersed to create abundantly. Such creativity fertilized the development of the principles and practices of therapeutic communities, psychoanalytic group therapy, the application of an analytic understanding to organizations and more. This article includes a consideration of how practice was influenced from these origins. This contribution has as a background the author working for over two years at the Cassel Hospital early in the 1990s and more recently attending a conference in January 2018 conducted at Northfield or Hollymoor Hospital, as it was originally, and remains, known. It includes some personal reflections.
Comment on Vollon, Gimenez and Bonnet: ‘The psychotic transference in groups’
Authors: Nitzgen Dieter
Published: September 2019

In his written work, Foulkes never gave a systematic account of psychosis, psychotic disturbances and psychotic transference(s). Instead we find scattered remarks and reflections on the subject of psychosis throughout his writings. However, it is noteworthy that his first psychoanalytic article (Foulkes, 1930) was dedicated to Observations on the significance of the name in a schizophrenic (Foulkes, 1990: 3–20). Moreover, in his first group analytic article (Foulkes and Lewis, 1944), he mentioned and encouraged the treatment of psychotic patients in mixed groups (Foulkes, 1984, case 8, 10, 11 and 12: 30–33) but cautioned that in a group ‘psychoses should not be in the majority’ and ‘groups with psychotics only were a different matter’ (Foulkes, 1984: 35). However, some his most consistent statements on psychosis are given in his late articles. For instance, the view that ‘undoubtedly, the person who later develops a psychosis, is also conditioned by his early group, and vice versa’ (Foulkes, 1990: 276). And the conviction that ‘psychotic mechanisms are operative in all of us, and that psychosis-like mechanisms and defences are produced very early’ (Foulkes, 1990: 276). However, he cautioned that ‘later psychotic illness’ should not be considered as ‘regressions to these early stages as one might say that neurosis or neurotic reactions are’ (Foulkes, 1990: 276; cf. Wälder, 1937). And although Foulkes acknowledged that ‘early development produces many of the phenomena that are stressed by Melanie Klein’ (Foulkes, 1990: 276; italics mine), he posited that they were ‘being brought about by the interaction of the whole family on these primitive levels’ (Foulkes, 1990: 276). ‘Complicated emotions’, he wrote, ‘can be felt even by the small child as actually represented and transmitted, however unconsciously, by the parents, brothers and sisters and so on’ (Foulkes, 1990: 276).
Do Teacher Credentials and Characteristics Affect Teacher Effectiveness in High School Economics?
Authors: Swinton John R. , Clark Chris
Published: September 2019

We use student-level administrative data from Georgia to examine how teacher characteristics affect student learning. Specifically, we examine students’ normalized end-of-course test scores for a required high school economics course. We develop two models. First, we examine returns to activities often linked to teacher effectiveness—experience, advanced degrees, National Board Certification, and curriculum-specific in-service workshops. Second, we investigate the importance of having teachers share characteristics with their students. Similar to many studies before us, we find little systematic link between any of the observable teacher characteristics and better student outcomes once we control for unobservable teacher characteristics. Of note, we do find that female students tend to perform better with female teachers than with male teachers. Overall, the results highlight the difficulty in relying on just one specific measure of teacher quality to ensure student performance.

The Role of Place in the Lives of Sex Workers: A Sociospatial Analysis of Two International Case Studies
Authors: Grittner Alison , Sitter Kathleen C.
Published: September 2019

This article conceptualizes how place-based analysis can generate innovative understandings of sex work and spatial justice, including ways in which stigma, well-being, and marginality are embodied in sex work places. Focusing on three interconnected dimensions of place—geographic location, material environment, and sociopower structures—this article examines the unexplored realm of place and sex work. Beginning with an analysis of existing sex work literature and knowledge relating to dimensions of place, we explicate the role of feminist ideologies, juridical contexts, and the built environment as the conceptual and analytic groundwork for a place-based understanding of sex work. Architectural spatial methods then generate a place-based analysis of two case study exemplars: the Residence in Western Canada and the Strichtplatz in Zurich, Switzerland. We conclude by considering avenues to incorporate place theory into sex work research and the social work discipline, ultimately advocating for research, policy, and practice that concomitantly address sex workers’ social and spatial oppression.
What Deters Child Sex Offenders? A Comparison Between Completed and Noncompleted Offenses
Authors: Wortley Richard , Leclerc Benoit , Reynald Danielle M. , Smallbone Stephen
Published: September 2019

This study examined the role of the reaction of the victim, the nature of the physical setting, and the proximity of third parties in deterring offenders from completing an act of child sexual abuse (CSA). A self-report study was conducted with 238 adult males serving a custodial sentence for CSA, of whom 82 identified an occasion in which they had tried to have sexual contact with a child but did not because they were stopped or discouraged. We examined the situational characteristics of the noncompleted offense and compared these with the most recent completed offense by the same offenders. The most common reason for stopping the noncompleted offense, given by more than half of the participants, was the negative reaction of the child, and in particular, the direct request by the child to stop. Actual or potential actions by third parties were the next most cited reasons, with around a quarter of cases stopped because the offender was interrupted. In comparison to the noncomplete offense, in the completed offense the child was more likely to be younger and to be perceived as a willing participant. The most common suggestion for what might have stopped the completed offense, endorsed almost universally, was a negative reaction from the child. Factors that increased the chance of being detected—someone being nearby and the possibility of being observed—were also strongly endorsed. We argue that the findings provide the basis for devising offense-focused prevention strategies for CSA.
Is Preventive Treatment for Individuals With Sexual Interest in Children Viable in a Discretionary Reporting Context?
Authors: Christofferson Sarah M. Beggs
Published: September 2019

This study explored the viability of preventive treatment services for individuals with sexual interest in children, in jurisdictions without mandatory reporting but where risk-related disclosures to authorities are permitted at therapists’ discretion. Health professionals ( N = 112) were surveyed regarding their comfort, confidence, knowledge of relevant legal provisions, and personal disclosure thresholds, in relation to a hypothetical scenario of a client confiding pedophilic interest to seek help. Findings were mixed regarding implications for prevention service viability. Despite the complexities of the legal and ethical context of the study setting (New Zealand), predictions regarding professionals’ uncertainty in relation to their legal and ethical duties, and displaying a bias toward disclosing information to authorities when permitted, were not fully borne out, although pervasive knowledge inaccuracies and associated training needs were revealed. Instead, general tendencies among respondents were toward comfort, confidence, and the inclination toward maintaining client confidentiality. Yet, widespread variance within the sample, and individuals’ thresholds appearing rather unpredictable on the basis of demographic or professional variables, highlights likely barriers for potential clients in feeling safe enough to come forward. Given that preventive treatment viability in this context relies on self-referral, it is suggested that a purpose-designed preventive treatment service, with clear accessible confidentiality and reporting policies that are well within the law, could be the best way forward for viable preventive treatment in discretionary reporting contexts.

This study examines data from Stop It Now!’s Helpline in the United States primarily over a 5-year, 3-month period and offers insights into the needs of individuals and families confronting issues related to child sexual abuse (CSA). Stop It Now!’s Helpline serves the global community by providing support, information, and guidance to those in need, such as helping to identify and respond to warning signs of sexually abusive behaviors in adults, adolescents, or children. More than 7,000 ( N = 7,122) nonidentifiable user records are the subject of this inquiry and reflect individuals who contacted the Helpline between December 1, 2012, and March 7, 2018. The article also places this analysis in a larger context through an overview that includes total user count of this service since its inception in 1995 ( N = 21,030).

Descriptive statistics revealed that the majority of Helpline users identified as bystanders, family members, or friends/acquaintances of an individual at risk to abuse. The majority of users knew both the person at risk to abuse (adult or youth) and the child at risk of being abused. Twelve percent of users had questions or concerns about their own feelings and/or behaviors that were or could be putting a child at risk of sexual abuse. Chi-square tests examined the relationship between Helpline contact type, level of assessment, and gender.

Findings provide insights into this hidden population of individuals at risk to abuse, those who have abused, as well as their friends and families who are seeking support. Study findings also reinforce the importance of CSA prevention helplines that focus on reducing the isolation and secrecy that creates conditions which make children more vulnerable to abuse. Implications for future research and prevention programming are also discussed.

Published: September 2019

In the 2017 final report of the Australia’s Royal Commission Into Institutional Responses to Child Sexual Abuse, recommendations noted the importance of school-based prevention efforts to create child-safe communities. In this study, we report on a national evaluation of the nature and availability of child sexual abuse prevention programs delivered in Australian primary schools. A survey instrument, anchored in empirical evidence, was distributed to all providers of child sexual abuse prevention programs in Australian primary schools serving children aged 4 to 13 years. Respondents were program coordinators or facilitators who provided data on 35 school-based child sexual abuse prevention programs that reached 631,720 children (approximately 26% of the Australian primary school student population) in 1 year. On average, each program reached 18,049 children in a calendar year (ranging from 200 to 80,000 children). Median child age for program exposure was 8 years. However, program duration was poorly reported so it was difficult to establish what program dosage was received. Most programs (80%-94%) covered specific item content, “always or often,” for 13 important areas of content, including five of seven items that had the strongest evidence of effectiveness, derived from a recent Cochrane Review (e.g., distinguishing appropriate and inappropriate touching). Programs less frequently addressed such content as safety in using technology and perpetrator strategies (e.g., grooming). The findings provide important information about the scope and nature of child sexual abuse prevention programs, and baseline data against which future program advancements can be tracked.

Difficulty controlling anger is a significant concern among combat veterans with posttraumatic stress disorder (PTSD), yet few controlled studies have examined the efficacy of anger treatments for this population. This study examined the effects of a group cognitive behavioral therapy (CBT) intervention compared with a group present-centered therapy (PCT) control condition in male and female combat veterans with PTSD. Thirty-six combat veterans with PTSD and anger difficulties began group treatment (CBT, n = 19; PCT, n = 17). Separate multilevel models of self-rated anger, PTSD symptoms, and disability were conducted using data from baseline, each of 12 treatment sessions, posttreatment, and 3- and 6-month follow-up time points. Significant decreases in anger and PTSD symptoms were observed over time, but no significant differences between CBT and PCT were observed on these outcomes. A significant interaction of therapy by time favoring the PCT condition was observed on disability scores. Gender differences were observed in dropout rates (i.e., 100% of female participants dropped out of CBT). Findings suggest that both CBT and PCT group therapy may be effective in reducing anger in combat veterans with PTSD. Results also highlight potential gender differences in response to group anger treatment.
Effects of Accumulated Short Bouts of Exercise on Weight and Obesity Indices in Adults: A Meta-Analysis
Authors: Kim Heontae , Reece Joel , Kang Minsoo
Published: September 2019

Objective:

To compile and quantify the effectiveness of accumulated short-bout exercise interventions on reducing the obesity indices in adults using meta-analysis.

Data Source:

PubMed, PsycINFO, CINAHL, Cochrane Library, and SportDiscus.

Study Inclusion and Exclusion Criteria:

(1) Description of a short-bout exercise trial (<30 minutes); (2) obesity indices must be measured pre- and postintervention; and (3) only adults and published in English.

Data Extraction:

Two independent reviewers extracted data and assessed the quality of the studies included. Of 3257 articles retrieved, 18 studies met the inclusion criteria. Based on the Downs and Black checklist, the methodological quality of the included studies was fairly robust.

Data Synthesis:

Pooled effect sizes (ESs) were calculated using a random effects model.

Results:

Average intervention length was approximately 16 weeks (ranged from 4 to 72 weeks). All weighted mean ES values for each obesity index measure were non-negative, ranging from small to large (ES = 0.33-0.96) in magnitude. Weighted mean ES for body mass (BM; n = 18; ES = 0.51, 95% confidence interval [CI] = 0.22-0.80), body mass index (BMI; n = 13; ES = 0.61, 95% CI = 0.24-0.97), waist circumference (n = 9; ES = 0.44, 95% CI = 0.15-0.73), body fat percentage (BF%; n = 8; ES = 0.33, 95% CI = 0.09-0.58), skinfold (n = 7; ES = 0.96, 95% CI = 0.39 -1.53), and fat mass (FM; n = 6; ES = 0.55, 95% CI = 0.21-0.90) were statistically significant. Moderator effects of intervention length (weeks) were observed for BM (Qbetween [Cochran’s Q: a measure of heterogeneity between studies] = 6.83, P < .05); BMI (Qbetween = 13.93, P < .05); and FM (Qbetween = 10.41, P < .05). Intervention length >10 weeks was more effective than shorter (≤10) intervention period for reducing BM, BMI, and FM.

Conclusion:

Accumulated short bouts of exercise have a beneficial effect on reducing the obesity indices among adults. The current study can help health researchers and practitioners in designing their intervention programs, which can be applied within schools, clinics, and communities.
Understanding Quality in Research: Avoiding Predatory Journals
Authors: Strong Genae
Published: September 2019

Peer-review publishing has long been the gold standard for disseminating research. The peer-review process holds researchers accountable for their work and conveys confidence that the article is of value to the reader. Predatory journals and publishing pose a global threat to the quality of scientific literature, accuracy of educational resources, and safety of patient care. Predatory publishing uses an exploitative business model, substandard quality control measures, and deceptive publishing practices. Given the proliferation of these journals and the extreme measures utilized to disguise substandard publishing practices, avoiding them can prove difficult. Understanding the nature of predatory publishing and how to recognize the warning signs provide helpful measures to authors, researchers, students, and readers. Additional resources known to help avoid predatory publishers have been discussed in addition to reviewing the Journal of Human Lactation guidelines for publishing.
Physical and mechanical properties of polyamide 6/polystyrene (PA6/PS) reinforced by PbO2 composites for X-ray shielding
Authors: Elbary AM Abd , Tammam MT
Published: September 2019

Thermal, electrical, as well as mechanical behavior of blends of polyamide 6/polystyrene (PA6/PS) (50/50 wt/wt%) loaded with different concentrations of lead dioxide (PbO2) were investigated for X-ray shielding. Thermal stability and hardness (shore D) of these composites are studied. Addition of PbO2 decreases the thermal stability of the prepared composites. Stability of thermal properties confirmed by determining the activation energy for the thermal decomposition of unfilled PA6/PS and filled composites according to the Horowitz and Metzger method. Dielectric properties of bulk PbO2 have been investigated as a function of frequency and temperature in the frequency range from 40 Hz to 5 × 106 Hz and in the temperature range from 293 K to 423 K. The characterization of the prepared composites is done using scanning electron microscope. With PbO2-loaded PA6/PS blends composites, the dielectric properties were significantly influenced by γ-irradiation effects that ε′ and [Formula: see text] values increase with radiation dose up to 100 kGy for samples loaded with PbO2. Linear attenuation coefficient μ and half-value layer (HVL) of all composites strongly depend on the concentration of the filler used and the applied voltage of X-ray machine. HVL of the obtained composites that loaded with 100 wt/wt% of PbO2 nearly 3 mm can be used as X-ray tube housing, equipment housings and castings, electronic devices protection, and so on.
