Adjustment Problems in Early Adulthood Among Victims of Childhood Physical Abuse: A Focus on Adolescent Risk and Protective Factors
Authors: Kuper Julie L. , Turanovic Jillian J.
Published: May 2019

Physical abuse in childhood places individuals at risk for many behavioral and mental health problems in adulthood. Nevertheless, not all abused children will ultimately experience these negative outcomes. Using a subsample of physically abused youth from the National Longitudinal Study of Adolescent to Adult Health, we examined whether protective and risk factors in adolescence (intelligence, family attachments, and neighborhood disadvantage) explained why some victims fared better in early adulthood. Outcomes of violent offending, depressive symptoms, and low self-esteem were examined. Family attachments were found to be protective against depressive symptoms and low self-esteem, while the effects of intelligence were more limited. These findings emphasize that there is marked variability in how physically abused children fare in early adulthood.
What does critical health education in schools look like? Two ethnographic narratives of critical practice
Authors: Fitzpatrick Katie , Allen Jean M
Published: May 2019

Background:

Many health education scholars over the last 20 years have argued that critical approaches to the discipline are needed. Despite these calls, there are few published examples of actual critical practice in action in school classrooms. Some have argued that part of the explanation for this lacuna lies in a dichotomy in the field between ‘traditional’ approaches to health education and more critical approaches.

Purpose and Methods:

This article draws on an ethnographic study of schools in Aotearoa New Zealand and shares two different narratives of what we identify as critical approaches to health education. New Zealand is unique in that health education is a credentialed subject in senior high school that allows access to national qualifications. We outline the approaches of two different teachers within this system, and evaluate these alongside key literature in the field, and five pedagogical themes.

Conclusions:

Teachers who engage with critical classroom practice are also likely to include traditional and biomedical teaching approaches. Rather than viewing this as problematic, we argue that health education programmes that value criticality will also value traditional forms of health knowledge, while simultaneously questioning them. Such an approach is necessarily messy but is more successful when teachers embrace a pedagogy of uncertainty.
Twentieth-Century Longitude: When Greenwich Moved
Authors: Kershaw Michael
Published: May 2019

By the beginning of the twentieth century, the meridian passing though the Royal Observatory at Greenwich had become a near-universal reference for place and time. It was the zero of longitude. But our current standard of zero longitude is about 100 metres away from the original. That mobility needs historical context: Greenwich began to move in the years after the First World War, when wireless techniques for the astronomical determination of longitude and the standardisation of time were developed, and has carried on moving ever since. In this article, I describe how twentieth-century techniques for the determination of longitude not only brought improved precision but also led to fundamental changes in our long-standing conventions of longitude. And I show how – despite its mobility – our current standard of zero longitude continues to respect the original.
Passivizability of Idioms: Has the Wrong Tree Been Barked Up?
Authors: Kyriacou Marianna , Conklin Kathy , Thompson Dominic
Published: May 2019

A growing number of studies support the partial compositionality of idiomatic phrases, while idioms are thought to vary in their syntactic flexibility. Some idioms, like kick the bucket, have been classified as inflexible and incapable of being passivized without losing their figurative interpretation (i.e., the bucket was kicked ≠ died). Crucially, this has never been substantiated by empirical findings. In the current study, we used eye-tracking to examine whether the passive forms of (flexible and inflexible) idioms retain or lose their figurative meaning. Active and passivized idioms ( he kicked the bucket/the bucket was kicked) and incongruous active and passive control phrases (he kicked the apple/the apple was kicked) were inserted in sentences biasing the figurative meaning of the respective idiom ( die). Active idioms served as a baseline. We hypothesized that if passivized idioms retain their figurative meaning ( the bucket was kicked = died), they should be processed more efficiently than the control phrases, since their figurative meaning would be congruous in the context. If, on the other hand, passivized idioms lose their figurative interpretation ( the bucket was kicked = the pail was kicked), then their meaning should be just as incongruous as that of both control phrases, in which case we would expect no difference in their processing. Eye movement patterns demonstrated a processing advantage for passivized idioms (flexible and inflexible) over control phrases, thus indicating that their figurative meaning was not compromised. These findings challenge classifications of idiom flexibility and highlight the creative nature of language.
Organ Donation and Declaration of Death: Combined Neurologic and Cardiopulmonary Standards
Authors: Doran Stephen E. , Vukov Joseph M.
Published: May 2019

Prolonged survival after the declaration of death by neurologic criteria creates ambiguity regarding the validity of this methodology. This ambiguity has perpetuated the debate among secular and nondissenting Catholic authors who question whether the neurologic standards are sufficient for the declaration of death of organ donors. Cardiopulmonary criteria are being increasingly used for organ donors who do not meet brain death standards. However, cardiopulmonary criteria are plagued by conflict of interest issues, arbitrary standards for candidacy, and the lack of standardized protocols for organ procurement. Combining the neurological and cardiopulmonary standards into a single protocol would mitigate the weaknesses of both and provide greater biologic and moral certainty that a donor of unpaired vital organs is indeed dead.

Before a person’s organs can be used for transplantation, he or she must be declared “brain-dead.” However, sometimes when someone is declared brain-dead, that person can be maintained on life-support for days or even weeks. This creates some confusion about whether the person has truly died. For patients who have a severe neurologic injury but are not brain-dead, organ donation can also occur after his or her heart stops beating. However, this protocol is more ambiguous and lacks standardized protocols. We propose that before a person can donate organs, he or she must first be declared brain-dead, and then his or her heart must irreversibly stop beating before organs are taken.
Short report: Inclusion of other in the self scale: An adaptation and exploration in a diverse community sample
Authors: Helgeson Vicki S. , Van Vleet Meredith
Published: May 2019

We adapted the widely used measure of relationship closeness, the Inclusion of Other in Self Scale (IOS), to assess communal coping (IOS-CC). Communal coping is a construct that reflects a shared appraisal of a stressor (“our problem” instead of “my problem”) and collaborative action to manage the stressor. We administered the IOS and the IOS-CC to a racially and economically diverse sample of persons with type 2 diabetes and their partners ( n = 207 couples) and examined how a subset ( n = 85 couples) interpreted the IOS-CC as well as the IOS. The IOS-CC was largely interpreted as intended. The IOS reflected interpersonal connection, as expected, but also a number of other relationship constructs. The IOS-CC and IOS were positively related, but empirically distinguished by stronger connections of the IOS-CC to communal coping and stronger connections of the IOS to relationship quality. Future researchers should consider using the IOS-CC to measure communal coping when a simple, visual, and less time-intensive measure is needed and consider the different ways the IOS is conceptualized by diverse populations.

Salmonella is a major foodborne pathogen and pork is one of the main sources of human salmonellosis. Understanding the pathogenesis and progression of the infection within the host is of interest to establish potential approaches to control the disease in pigs. The present study evaluates factors such as intestinal colonization, fecal shedding, and pathogen persistence by 2 studies using experimental challenge with Salmonella Typhimurium in weaned pigs and euthanasia at different time points (1, 2, and 6 and 2, 14, and 30 days postinfection [dpi], respectively). Histopathology of intestine at early time points (1 dpi and 2 dpi) showed severe damage to the epithelium together with an increase in polymorphonuclear cells and macrophages ( P < .001), particularly in jejunum and ileum. Large quantities of Salmonella were detected within the contents of the ileum, cecum, and colon in early infection. Salmonella could also be observed in the medulla of tonsils and mesenteric lymph nodes. From 6 dpi onward, signs of recovery were observed, with progressive restoration of the epithelium, reduction of the inflammatory infiltrate, and elimination of Salmonella from the mucosa. Concentration of Salmonella in feces and ileum content decreased, but shedding did not cease even at 4 weeks after infection. Persistence of the bacteria in mesenteric lymph nodes was identified within the connective tissue at 14 and 30 dpi. Our results demonstrate a recovery of the disease after an initial acute phase but also show persistence within the lumen and surrounding lymphoid tissue. These findings are relevant to developing effective control strategies.
Rainer Gross Award Lecture 2018: The Childhood Plasma Proteome: Discovering its Applications in Public Health Nutrition
Authors: Lee Sun Eun , Schulze Kerry , West Keith P.
Published: May 2019

Millions of children have multiple nutritional deficiencies, threatening their optimal growth, development, and quality of life. Revealing the magnitude and underlying biology of malnutrition from a greatly expanded set of practical biomarkers will be critical for developing appropriately targeted and evaluated interventions. However, our abilities to reveal and quantify the many forms of malnutrition, other than by anthropometry and occasional use of biochemical indicators, remain limited. Plasma proteomics holds great promise as a basis for developing novel biomarkers to facilitate assessment of growth, micronutrient status, inflammation, and other health status of populations while also providing biological insight into causes and adverse consequences of malnutrition. Discovery-driven plasma proteomics has been shown to reveal functional biomarkers of nutritional and health status, identifying clusters of protein biomarkers from which field-friendly, comprehensive, and low-cost methods could be developed for assessing populations. In this brief review, we summarize several key discoveries to date and discuss potential public health applications of proteomics-based biomarkers in reporting the extent and metabolic features of undernutrition in low-resource settings.
Boris Groys and the total art of Stalinism
Authors: He Yanli
Published: May 2019

This paper’s core concern is Boris Groys’ theory of the total art of Stalinism, which is devoted to rewriting Soviet art history and reinterpreting Socialist Realism from the perspective of the equal rights between political and artistic Art Power. The aim of this article is to decode Groys and the total art of Stalinism, based on answering the following three questions: 1) why did Groys want to rewrite Soviet art history? 2) How did Groys re-narrate Soviet art history? 3) What are the pros and cons of his reordering of the total art of Stalinism? Groys offers an effective paradigm that could rethink two theoretical genres: a) other Socialist Realisms inside or outside the Soviet bloc, during or after the Soviet era; b) the aesthetical rights of political artworks before, during and after the Cold War, and the historical debates about art, especially about art for art’s sake, or art for political propaganda. However, Groys’ total art of Stalinism and its core theory of the Socialist Realism frame hides some dangers of aestheticizing Stalin and Stalinism.
Early Assessment of Computer-Assisted Malarplasty: A Novel Methodology for Both Reduction and Augmentation
Authors: Keyhan Seied Omid , Fallahi Hamid Reza , Azari Abbas , Cheshmi Behzad
Published: May 2019

The aim of this study is to introduce a sophisticated method for malar reduction or augmentation through an additive manufacturing technology. Using the results of data analysis in KAVEH software, a surgical guide will be developed for both sides, which will be used in a zygomatic sandwich osteotomy. Both reduction and augmentation malarplasty could be done after osteotomy with outward or inward rotation of the zygomatic complex around the zygomatic arch based on pre-surgical analysis. We recommend usage of additive manufacturing technology in malar augmentation to obtain more precise and predictable outcomes.
Experimental and numerical investigation of wrinkling and tube ovality in the rotary draw bending process
Authors: Safdarian R
Published: May 2019

The tube wrinkling, ovality, and fracture are the main defects in the rotary draw bending process, which happen by incorrect selection of process parameters. In the present study, the wrinkling, fracture, and ovality of BS 3059 steel tube in the rotary draw bending were investigated using the experimental tests and the finite element method. The numerical results were verified using the experimental tests for tube ovality prediction. The tube fracture was predicted using the Gurson–Tvergaard–Needleman damage model in the rotary draw bending numerical simulations. The design of experiment based on the response surface method and the finite element method was used to investigate the effects of rotary draw bending parameters such as boosting velocity of pressure die, mandrel position, number of balls, and pressure of pressure die on the wrinkling, fracture, and tube ovality. The experimental and numerical results indicated that the mandrel position was one of the main parameters, which influence the tube ovality. The tube ovality and wrinkling increased with the increase in the mandrel position.
Fatigue damage of a heavy-haul railway tunnel invert under a 33-tonne axle cyclic load
Authors: Wang Mingnian , Zhao Yinting , Li Ziqiang , Liu Dagang , Yu Li
Published: May 2019

The average cyclic load of heavy-haul railway trains is generally larger than that of a conventional mixed passenger and freight railway. This load leads to more severe fatigue damage to structures, including the concrete in a tunnel invert. This study focuses on the fatigue damage of a tunnel invert under a cyclic load of 33 tonnes. The damage classifications for the tunnel inverts are given based on field investigations. With large-scale in-situ tests on the Zhang-Tang Heavy-Haul Railway Tunnel, the pressure–time distributions for the additional dynamic stresses on the surface of the track-bed for various classes of the surrounding rock are proposed. They were subsequently validated against numerical simulation using the ANSYS Workbench module. Fatigue damage of the tunnel invert is demonstrated using both numerical and monitoring methods. It has been observed that the damage to the tunnel invert becomes severe and extensive if the quality of the surrounding rock degrades. Damage zones develop first at the top of the invert and then expand to a deeper position, depending on the rock grade.
Effects of psoriasis treatment on genital warts: a case report
Authors: Campoli Marco , Cinotti Elisa , Fimiani Michele , Pellegrino Michele , Tognetti Linda , Rubegni Pietro
Published: May 2019

The use of immunosuppressive drugs predisposes to infections, as they block the most important stage in antiviral defense, which is the cytotoxic T-lymphocyte HLA-dependent response. We report a case of extensive genital warts in a young woman on therapy for psoriasis with cyclosporine, afterwards successfully treated with an anti-tumor necrosis factor alpha (TNF-α) agent. Cyclosporine may predispose to the reactivation of latent infections and may favor the clinical manifestations of human papillomavirus (HPV)-related diseases, due to the inhibition of cell-mediated immunity that plays a crucial role in controlling HPV infections. In the literature the relationship between HPV and TNF-blockers has not yet been clearly defined. Our case underlines that the prompt interruption of cyclosporine can induce a complete regression of warts without any additional treatment and adds evidence to the possible use of anti-TNF-α in patients with psoriasis and genital warts.
Dignity at stake: Caring for persons with impaired autonomy

Published: May 2019

Dignity, usually considered an essential ethical value in healthcare, is a relatively complex, multifaceted concept. However, healthcare professionals often have only a vague idea of what it means to respect dignity when providing care, especially for persons with impaired autonomy. This article focuses on two concepts of dignity, human dignity and dignity of identity, and aims to analyse how these concepts can be applied in the care for persons with impaired autonomy and in furthering the practice of respect and protection from harm. Three vignettes were designed to illustrate typical caring situations involving patients with mild to severely impaired autonomy, including patients with cognitive impairments. In situations like these, there is a risk of the patient’s dignity being disrespected and violated. The vignettes were then analysed with respect to the two concepts of dignity to find out whether this approach can illuminate what is at stake in these situations and to provide an understanding of which measures could safeguard the dignity of these patients. The analysis showed that there are profound ethical challenges in the daily care of persons with impaired autonomy. We suggest that these two concepts of human dignity could help guide healthcare professionals to develop practical skills in person-centred, ethically grounded care, where the patient’s wishes and needs are the starting point.
Potemkin redux: the re-disorganisation of public mental health services in Australia
Authors: Looi Jeffrey CL , Kisely Stephen R
Published: May 2019

Objectives:

This paper discusses the phenomenon of re-disorganisation as it applies to publicly-funded mental health services. The term refers to the constant reorganisation of services in the absence of evidence and of unclear benefit. We illustrate the problems of re-disorganisation with some hypothetical examples, as well as discussing the context of these problems.

Conclusions:

The re-disorganisation of public mental health services may be considered a politically expedient administrative response resulting in the illusion of activity and progress. It may be intentional or unintentional. Re-disorganisation can detract from effective policy, planning and implementation of improvements in provision of public mental health services.

Authors: Ay Melike Ayca , Akyar Imatullah
Published: May 2019

Introduction: In some countries, family members are not involved in routine pediatric cancer psychosocial care although it is essential. This integrative review aims to determine the extent of research on family members of pediatric cancer patients in Turkey. Method: Four main keywords were used: parent/sibling/family, child/pediatric, cancer and psychosocial outcomes to search articles on PubMed, EKUAL, ULAKBİM, WOS databases (limited to 1997-2017). Among first 317 hits, 284 records were excluded. Of 33 eligible articles, 14 were excluded due to sample characteristics. Results: Research on psychosocial effects of pediatric cancer on family members is mostly descriptive and offers moderate-quality evidence. The reported psychosocial effects are (1) depression, anxiety, hopelessness, acceptance; (2) burden of care, quality of life, posttraumatic stress disorder; and (3) need for social support, information. Discussion: This study will contribute to the literature and help for the planning of protective psychosocial interventions for family members of children with cancer in Turkey.
Modelling of a cantilevered energy harvester with partial piezoelectric coverage and shunted to practical interface circuits
Authors: Hu Guobiao , Tang Lihua , Liang Junrui , Das Raj
Published: May 2019

This article presents a modelling methodology for a cantilevered energy harvester with partial piezoelectric coverage and shunted to practical power conditioning interface circuits. First, the distributed parameter model of the partially covered piezoelectric energy harvester is developed and the associated analytical solution is derived. Subsequently, the single-degree-of-freedom representation model is developed and the explicit expressions of equivalent lumped parameters are derived by taking the static deflection as the approximated fundamental vibration mode. Based on the comparison with the single-mode expression of the distributed parameter model, a correction factor is proposed to improve the accuracy of the single-degree-of-freedom model. The results of both the distributed parameter and the corrected single-degree-of-freedom models are compared. The accuracy of the corrected single-degree-of-freedom representation model is verified against the analytical and the finite element models. Finally, practical interface circuits including the standard energy harvesting circuit and the parallel synchronized switch harvesting on inductor circuit are considered. A modified equivalent impedance modelling method is proposed for the analysis of the standard energy harvesting and parallel synchronized switch harvesting on inductor circuits. The results of the modified equivalent impedance modelling method are verified against the existing method in the literature.
Critical Language and Discourse Awareness in Management Education
Authors: Darics Erika
Published: May 2019

Communication and, through it, language have become key elements of business and organizational life. How organizations interact within their walls and with the outside world fundamentally affects business processes, creating organizational culture, shaping public perceptions, and influencing consumer choices. This essay calls for a greater acknowledgment of language and communication and suggests that management educators may want to review how they are incorporated in management education curricula. Expanding on the skill-based approach typically adopted in business school classes, the essay points to the utility of exposing business students to the dual function of language as a means of doing work and as a social action that constitutes social reality. Drawing on examples from scholarship in linguistics and discourse analysis, the essay demonstrates that the ability to notice, identify, and reflect on linguistic and discourse practices is a crucial managerial skill. Nurturing such analytical and thinking skills enables people to become not only better communicators but also critical thinkers able to understand and challenge when social control, power, or injustice is enacted in organizations.
Building a Culture of Honor and Integrity in a Business School
Authors: Eury Jennifer L. , Treviño Linda Klebe
Published: May 2019

We describe a unique co-curricular honor and integrity program at a large, research university’s business school. We discuss the evolution of the program as well as the array of stakeholders who were involved in its early development and sustenance. We use an ethical culture template to highlight the formal and informal systems, and we discuss ongoing efforts to assess its effectiveness. We also reveal multiple challenges associated with building and sustaining a culture of honor and integrity for students, faculty, and staff. This program overview provides members of any business school community with a theory-based, but practical, roadmap for moving beyond finding a space in the academic curriculum to promote ethical behavior to developing and implementing a co-curricular honor and integrity program.
Primary Clear Cell Adenocarcinoma of the Vulva: A Case Study With Mutation Analysis and Literature Review

Published: May 2019

Primary vulvar clear cell carcinoma (CCC) is extremely rare. In this article, we report a primary vulvar CCC along with immunohistochemical and gene mutation analyses results and literature review to discuss the clinicopathological features and tumorigenesis of this rare tumor. A 70-year-old (gravida 2 para 2) Japanese woman complained of bleeding from a vulvar mass at a past episiotomy site. A 1.8 × 1.8 × 0.5 cm exophytic sessile mass was present on the vestibular area inside the left labium minora. Radical local excision of the tumor and resection of the inguinal lymph nodes on both sides were performed. Histopathology revealed a vulvar CCC with immunohistochemical positivity for PAX8, HNF-1β, ER, and CA125, and negativity for p16, CD10, GATA3, PTEN, and PAX2, suggesting its Müllerian origin. No lymph node metastasis was observed. The tumor was a 5-mm exophytic growth without deep stromal invasion; thus, it was difficult to measure the invasion depth assuming a squamous cell carcinoma. To investigate pathogenic/oncogenic mutations in 50 cancer-related genes, we used the AmpliSeq Cancer Hotspot Panel. However, no pathogenic/oncogenic mutations were detected. Literature review revealed that most cases of vulvar CCC are associated with vulvar endometriosis. In particular, cases with clinically evident endometriosis at the episiotomy scar should be carefully observed. Evidence-based pathological stages of vulvar adenocarcinoma including CCC remain to be established owing to its rarity, with nationwide or global accumulation of cases required in future.
Investigation of the one-dimensional transient heat conduction problem of a coated high strength steel plate
Authors: Yang Yang , Dai Hong-Liang , Ye Chao , Xu Wei-Li , Luo Ai-Hui
Published: May 2019

In this paper, the one-dimensional transient heat conduction problem is investigated of a coated high strength steel (HSS) plate which is composed of two coating layers and a HSS layer. As the coating is extremely thin, non-Fourier heat conduction is applied to this part, while the steel part is analyzed by Fourier conduction. Then the temperature increment equations are obtained, which can be calculated by the Newmark method. The effects of thermal relaxation time, temperature boundary conditions, and coating parameters on temperature increment distribution of the coated HSS plate are also presented. Thus, the one-dimensional transient heat conduction problem of a coated HSS plate can be solved, which contributes to practical application and engineering design.
Stability of shock wave structures in nonlinear elastic media

Published: May 2019

The stationary structure stability of discontinuous solutions to nonlinear hyperbolic equations describing the propagation of quasi-transverse waves with velocities close to characteristic ones are studied. A procedure to analyze spectral (linear) stability of these solutions is described. The main focus is the stability analysis of special discontinuities, the stationary structure of which is represented by the integral curve connecting two saddle points corresponding to the states in front of and behind the discontinuity. This analysis is done using the properties of the Evans function, an analytic function on the right complex half-plane, which has zeros in this domain if and only if there exist unstable modes of linearization around a solution representing a special discontinuity with the structure.
Exploring Neuromuscular Electrical Stimulation Intensity Effects on Multifidus Muscle Activity in Adults With Chronic Low Back Pain: An Ultrasound Imaging–Informed Investigation
Authors: Sions Jaclyn Megan , Crippen DeJ’a Chyanna , Hicks Gregory Evan , Alroumi Abdulmohsen Meshari , Manal Tara Jo , Pohlig Ryan Todd
Published: May 2019

Study design:

Cross-sectional study.

Background:

Neuromuscular electrical stimulation (NMES) is an effective tool for stimulating multifidus muscle contractions. Ultrasound imaging (USI) is valid and reliable for quantifying multifidus activity represented by percent thickness change from a resting to contracted state. Thus, USI may be used to help determine optimal NMES intensity.

Objectives:

To explore NMES intensity effects on multifidus thickening in adults with chronic low back pain (CLBP).

Methods:

Sixty patients with CLBP participated. L4/5 multifidus ultrasound images were obtained and percent thickness change from a resting to a contracted state was determined at baseline with a limb lift and during NMES application. During NMES, the examiner recorded the intensity, in milliampere, when the multifidus first started to thicken as observed with USI. The examiner also recorded the NMES intensity that resulted in no further multifidus thickening (ie, high-tolerance group) or, in cases where maximal thickening was not observed, the NMES intensity of the submaximal contraction (ie, low-tolerance group). Differences between participants with high versus low NMES tolerance were evaluated.

Results:

During NMES, the multifidus began thickening at a higher intensity for the high-tolerance group (n = 39), that is, 34 mA, compared with the low-tolerance group (n = 21), that is, 32 mA ( P = .001). A greater mean intensity in the high-tolerance group, that is, 62 mA, as compared to 45 mA in the low-tolerance group, resulted in a larger percent thickness change, that is, 30.89% compared to 20.60%, respectively ( P < .001).

Conclusions:

Results provide clinicians with NMES intensity targets to facilitate multifidus muscle thickening, which provides insight into muscle activity.
Collaborative care in ‘Youth One Stop Shops’ in New Zealand: Hidden, time-consuming, essential
Authors: Garrett Susan , Pullon Susan , Morgan Sonya , McKinlay Eileen
Published: May 2019

Young people in New Zealand have high morbidity but low service utilization rates. Dedicated youth services ‘Youth One Stop Shops’ provide ‘wraparound’ health and social care. However, little is understood about how staff within these services interact with each other or with external agencies to provide this specialist care. This article reports on volume and type of internal and inter-agency health and social service staff–staff interactions, to better understand elements of potential collaboration in day-to-day practice. An observational, case-study approach was utilized. Four dedicated youth services recorded data over three-month periods about a selected number of high-use clients. Youth service staff recorded all interactions with colleagues within their organization and staff from external services. A large volume of non-patient contact work was revealed, with a high proportion of ‘complex/involved’ interactions recorded. The range and diversity of external agencies with which youth service staff interacted with to meet the needs of young people was extensive and complex. The focus on ‘information sharing’ and ‘complex/involved’ interactions demonstrates a well-coordinated, wraparound service delivery model. Current funding formulae take inadequate account of the volume of non-patient contact work that youth services provide for high-needs young people.
Indirect contact in social networks: Challenging common interpretations of the extended contact hypothesis
Authors: Stark Tobias H.
Published: May 2019

According to the extended contact hypothesis, direct intergroup contact is not necessary for prejudice reduction; it suffices to know that ingroup friends have outgroup friends. However, extended contact is typically measured in a way that does not clarify whether people know the outgroup friend of their ingroup friend or whether they are even direct friends. A social network approach is used to compare extended contact when ingroup friends’ outgroup friends are not direct friends (open triads) to when there is a direct friendship with some (mixed triads) or all of the ingroup friends’ outgroup friends (closed triads). Results from a nonprobability sample in the US predicting feelings toward Black people ( N = 313) and from a representative sample in the Netherlands predicting attitudes toward immigrants ( N = 818) show that extended contact reduces prejudice only when some of the outgroup friends of one’s ingroup friends are known. This suggests that the extended contact effect should not be interpreted as providing a solution for situations where direct contact with outgroup members is not possible.
‘Dehumanized housing’ and the ideology of property as a social function
Authors: Davy Benjamin
Published: May 2019

For about 250 years, private property has been ideologized as an instrument of the owners’ power to exclude. The most popular expression of the ideology of exclusion (although not his exclusive invention) is attributed to Sir William Blackstone. Speculative vacancies, a recent development in the real estate industry criticized by the UN Special Rapporteur on housing, emphasize the anti-social ideology of Blackstonian property. The article suggests that an ideology proposed by the French jurist Léon Duguit should be considered as an alternative. Based on the teachings of Comte and Durkheim, Duguit rejected the idea of property as a right and treated property as a social function. His views offer spatial planners new opportunities to define the content and boundaries of private property in land.
Help Wanted? A Narrative Look at Penal Welfarism ‘From Below’
Authors: Dollinger Bernd
Published: May 2019

This article explores principles of penal welfarism. For a number of years, there has been a wide-ranging debate on the impact of penal welfarism and on its transformation or indeed its possible supersedence. To date, however, discussions have rarely started with those directly affected (‘from below’) and asked how welfarist measures are experienced and perceived by young people who have been charged with or convicted of offences. This is the approach taken here as I focus on young defendants in the context of their trial. The young people describe in detail problematic life stories and personal challenges. However, the majority reject any attempt to label them as cases for education or rehabilitation. Help in the respondents’ view should primarily resolve specific, pragmatic problems, and not interfere with their identity.
Storying special objects: Material culture, narrative identity and life story work for children in care
Authors: Watson Debbie , Hahn Rachel , Staines Jo
Published: May 2019

This paper considers the importance of material objects for looked after and adopted children integrated as part of life story work practices. Conducting life story work is believed to be good practice within direct work with looked after children in England and there are a range of diverse practices, including life story books, later life letters and memory boxes. Through a creative design project developing a playful memory product for looked after children, we have had the opportunity to capture sector perspectives on life story work approaches and these are interspersed throughout this commentary. Combining multi-disciplinary theoretical perspectives and these sector insights, we explore how special material objects are important for children’s identity and continuity of sense of self. The paper highlights the importance of children telling their own stories of these objects, giving them agency and control over their life story narratives. In a context of austerity, life story work may not be prioritised by social workers who have many other competing demands and limited resources. We emphasise the need for professionals to recognise the value children give to objects and to provide them with opportunities to both keep these safe during placement moves and to tell their own story through their objects alongside more traditional, formal life story work. The recommendations have implications for children in out of home care in many country contexts, not just England where the research has been conducted.
Monitoring of human neuromusculoskeletal system performance through model-based fusion of electromyogram signals and kinematic/dynamic variables
Authors: Xie Yu Yang , Djurdjanovic Dragan
Published: May 2019

This article demonstrates feasibility of utilizing model-based approach for monitoring the performance of human neuromusculoskeletal systems. The performance monitoring method utilizes an autoregressive moving-average model with exogenous inputs to link signatures extracted from electromyogram signals, to the forces produced by the limbs and limb velocities. This model is then utilized to quantify and track changes in the neuromusculoskeletal system dynamics over time. The changes were modeled using a measure of overlap between the distribution of 1-step-ahead model prediction errors observed at the beginning of the exercise, when the subject was rested, and 1-step-ahead prediction errors observed at any other time during exercise. As the subjects proceeded with their exercises and got increasingly tired, the distribution of modeling errors changed and diverged from the initially observed one, causing the overlap between the original and the most recent distributions of modeling errors, referred to as the Freshness Similarity Index, to decrease. Thus, Freshness Similarity Index could be used as a quantitative measure of the level of degradation the neuromusculoskeletal system performance through the exercise. The methodology was evaluated in two experiments, one related to an activity involving lower limb contractions, and the other involving jaw joint movements. In both cases, a decreasing trend in the Freshness Similarity Index clearly illustrated changes in neuromusculoskeletal system performance as exercise progressed. Furthermore, after rest, Freshness Similarity Index observed in both exercises recovered to their original levels, quantitatively and meaningfully showing that the corresponding neuromusculoskeletal systems of the two subjects indeed rested.

This article examines effects of political party affiliation on U.S. young adults’ political participation across age and historical time. Using national U.S. longitudinal Monitoring the Future data from youth aged 18 to 30 years, we estimate effects of partisanship (Democrat, Republican, Other) on change in youth’s electoral and political voice participation with age, and test whether effects differ between 1976 and 2003. Political engagement and partisanship declined for young adults over several decades. Partisanship had a consistent positive effect on electoral participation across age and cohort. Democratic youth were higher on nonelectoral participation for some cohorts, and Democrats and Republican youth showed growth in nonelectoral participation at different historical moments. Although younger cohorts of Americans are less politically engaged based on available measures, political parties still remain a powerful force for political participation among those who choose to affiliate. Youth’s partisan attachments and political behavior are best understood in historical context.

Endovenous thermal ablation (EVTA) has become the mainstay of treatment for symptomatic varicose veins in the setting of saphenous vein insufficiency. We observed 5 iatrogenic arteriovenous fistulas (AVFs) following thermal ablation of the great saphenous vein (GSV). Postprocedure duplex ultrasound (DUS) results were analyzed for the presence of AVF in any location along or adjacent to the treated saphenous veins. Cases were prospectively followed. English literature was reviewed for any other published reports of AVF after EVTA. Data were compiled using our 5 cases, 2 cases were shared with us by colleagues and 20 cases were reported in the literature. Our center has performed more than 4000 (4155) cases of EVTA over the past 15 years. Five cases of AVFs were detected, 3 were found in asymptomatic patients during routine post-EVTA surveillance. The additional 2 cases presented with signs or symptoms which prompted a DUS after ablation. Including cases in the literature, we were able to identify 2 different types of AVFs. The first type of AVF was demonstrated in 13 cases where the AVF occurred along the treated vein. All of these cases involved ablation of the GSV and 90% of these showed signs of recanalization. The second type of AVF was seen in 14 additional cases where the AVF involved a vein segment adjacent to or remote from the ablated vein. The second type occurred in the GSV in 5 cases, external iliac vein (EIV) in 3 cases, and in the popliteal vein in 5 cases. There is 1 reported case of AVF involving the sural artery after perforator vein EVTA. Three of the type 1 cases were followed and spontaneously resolved; 3 of the type 1 cases were treated with surgical ligation with unreported outcomes. Seven cases did not report any follow-up information. Seven of the type 2 cases were treated, and had spontaneous resolution and 7 were not treated. The follow-up on these cases ranged from 1 month to 6 years. Thermal ablation can result in AVF either along the length of the treated vein or adjacent to the area of ablation. Further study would help elucidate the cause and treatment algorithms.
The effects of cue placement on the relative dominance of boundaries and landmark arrays in goal localization

Two types of visual features are identified as reference points used by individuals to encode locations: surface-based boundaries and discrete-object-based landmarks. Previous research show that learning locations relative to a boundary can overshadow learning relative to a landmark, but not vice versa, suggesting that environmental boundaries play a privileged role in representing individual locations. However, other research has revealed that a less accurate cognitive map is derived from boundary-related learning than from landmark-related learning, suggesting that a boundary is less privileged in representing inter-location spatial relations. The current study aims to reconcile these inconsistent findings. Experiment 1, using both a cue-competition paradigm and a cognitive mapping task, replicated the finding that participants preferred a circular boundary to a four-landmark array for encoding four locations (1A), but that the cognitive maps of the locations derived from the landmark array were more accurate (1B). Using the cue-competition paradigm, Experiments 2-4 manipulated the placement and distinctiveness of the two cues. The results showed that manipulating the placement of the landmark array effectively modulated the relative reliance upon the boundary/landmark-array in encoding individual location. Whereas increasing the distinctiveness of the landmark-array alone is not sufficient to eliminate the boundary advantage in localization. We propose that the boundary privilege occurs in selecting reference points for encoding locations due to its relative peripheral placement in the environment, whereas the landmark advantage occurs in inferring inter-location spatial relations due to the common reference point provided by the single landmark.
The epidemiology of scaphoid fractures in Sweden: a nationwide registry study

The epidemiology of scaphoid fractures has been described in limited populations, and incidence reports have been inconsistent. We investigated the nationwide incidence of scaphoid fractures by evaluating data on 34,377 patients in the Swedish National Patient Register for the years 2006–2015 regarding diagnosis, age, sex and treatment. The data were validated in 300 random patients, and incidence rates were adjusted accordingly. Forty-one per cent of the initially diagnosed fractures were false positives. The adjusted true fracture incidence rate was 22 per 100,000 person-years. During the decade studied incidence rates decreased in younger men and increased in middle-aged women. The incidence of surgical treatment vs. non-operative treatment did not change over time. Men were treated surgically more often than women (6% vs. 3%) and had a greater risk for nonunion (3% vs. 1%).

Introduction

The EVOLVE implant (Wright Medical Technology, Arlington, TN, USA) is a modular loose-fitting radial head prosthesis. The primary objective was to synthesize all available literature investigating the midterm clinical outcomes of the EVOLVE implant.

Materials and methods

An electronic literature search in Pubmed/Medline, Scopus, EMBASE, and Cochrane library was performed querying for studies published in 2000–2017. Articles describing clinical and radiographical outcomes as well as reoperation were included. Outcomes of interest included range of motion, Mayo Elbow Performance Score, Disabilities of the Arm Shoulder and Hand, radiographic outcome, and reason for reoperation.

Results

A total of five articles consisting of 146 patients with EVOLVE implants were included. Mean patient age was 57.4 years (range 22–84), and 43.8% were males (n = 64). Mean follow-up was 4.8 years (range 1–14). Mean Mayo Elbow Performance Score and Disabilities of the Arm Shoulder and Hand score were 87.6 (range 30–100) and 18.9 (range 0–82), respectively. Midterm clinical results were good or excellent (Mayo Elbow Performance Score > 74) in 94 patients. Reoperation was observed in 12 patients, with implant revision required in 2 patients. The primary reason for reoperation was persistent stiffness (n = 9).

Conclusion

Midterm outcomes of EVOLVE radial head prosthesis are satisfactory, and associated complication rates are low. Loose-fit implant method appears to be a reliable approach to avoid failure of radial head prosthesis by painful loosening.
