Clinical Features of Tourette Syndrome
Authors: Gill Chandler E. , Kompoliti Katie
Published: October 2019

Tourette syndrome is a multifaceted disorder characterized by multiple motor and at least one vocal tics that start in childhood, persist for at least 1 year, and cannot be attributed to another medical condition or exposure to medications/drugs. Clinical diagnostic criteria are available, and identification of tics is typically straightforward based on characteristic appearance and features. Diagnostic uncertainty can rarely arise in cases of mild tics, atypical features, certain psychiatric comorbidities, and other non-tic movement disorders. Comorbid psychopathology, including attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive behaviors/obsessive-compulsive disorder, affects the majority of patients and is correlated with disease severity and the presence of additional psychiatric behaviors. The severity of tics often improves after adolescence, whereas psychiatric symptoms typically persist. The subset of patients in whom tics persist into adulthood experience higher rates of anxiety, and lower self-esteem, socioeconomic status, and quality of life; the relative contribution of motor tics and psychopathology is not fully understood.

This article summarizes the clinical features of Tourette syndrome, including major diagnostic criteria, unique features of tics, and key aspects that differentiate tics from common mimics and chameleons. Comorbid psychiatric conditions and their impact on phenotype and quality of life are described. Finally, current understanding of the natural history is summarized, including limited research in adults with Tourette syndrome.

Published: October 2019

Chitin nanocrystal is a biocompatible and biodegradable nanofiller, with great potential in enhancing the mechanical and biological properties of polymers. Poly(caprolactone-diol citrate) is a kind of citrate-based biodegradable elastomer prepared by an additive-free melt polycondensation of polycaprolactone-diol and citric acid coupled with subsequent thermocuring. Here, a facile casting/evaporation method was utilized to prepare full biodegradable poly(caprolactone-diol citrate)/chitin nanocrystal nanocomposites, and their structure and properties were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, uniaxial tensile test, dynamic mechanical analysis, surface wettability and swelling analysis, thermogravimetric analysis, in vitro degradation, and cytocompatibility test. The results showed the chitin nanocrystals were uniformly distributed in the poly(caprolactone-diol citrate) matrix; with increasing chitin nanocrystal loading, the tensile modulus and strength significantly increased; furthermore, the incorporation of chitin nanocrystals endowed the poly(caprolactone-diol citrate) with more hydrophilicity, lower swelling in phosphate buffered saline solution, slow degradation rate, and greatly improved cytocompatibility. Thus, the chitin nanocrystal was a good bio-based nanofiller that could be used to tune the properties of poly(caprolactone-diol citrate) degradable bioelastomer.

Sexual violence has been found to have psychosocial and sexual ramifications for men who have sex with men (MSM) but has not been studied in the Middle East. We assessed the prevalence and correlates of experiences of child and post-child sexual violence among young MSM residing in Beirut, Lebanon. In total, 226 MSM, aged 18 to 29, were recruited with long-chain peer referrals and administered a survey that included questions on history of being pressured to have sex, as well as specific forms of sexual harassment and abuse, in addition to measures of psychosocial functioning and sexual behavior. Logistic regression analysis was used to examine correlates of child sex abuse and experiences of sexual violence post-childhood; 17.3% experienced sexual abuse as a child (below age 13), while 63.3% experienced any form of sexual violence post-childhood—furthermore, 48.7% had experienced being forced or pressured to have sex during their lifetime, including 32.3% prior to age 18. Participants who experienced child sex abuse were more likely to experience abusive relationships in adulthood, as well as at least one type of sexual harassment/abuse post-childhood. Experience of any sexual violence post-childhood was correlated with greater recent sexuality-related discrimination and more recent male sex partners. These findings reveal a high prevalence of sexual violence among MSM in Beirut, both in childhood and post-childhood. More research within the Middle East is needed to better understand the drivers of sexual violence in this population, and how to best provide prevention and coping services.

Published: October 2019

Health care providers (HCPs) who directly interact with women play a critical role in intimate partner violence (IPV) prevention and response. The aim of this study was to identify the structural and interpersonal barriers to IPV response among HCPs working in public health clinics in Santo André, Brazil. Eligible participants included all HCPs providing direct care to individuals at three public health clinics. Participants self-administered an adapted Knowledge, Attitudes, and Practices survey on IPV. Data were analyzed using Epi Info 7 and SAS 9.4. 114 HCPs completed surveys. Less than half of HCPs (41%, n = 34) reported ever having asked a woman about abuse in the past year. HCPs who perceived fewer barriers were more likely to report asking about IPV. The top three reported barriers to asking women about IPV included the following: few opportunities for one-on-one interaction (77%, n = 65), a lack of privacy (71%, n = 60), and fear of offending women (71%, n = 60). Fewer providers who perceived the barriers of lack of privacy asked about IPV (50.8%, n = 33 compared with 84.2%, n = 16; p < .05); less providers who perceived few opportunities for private patient interactions asked about IPV (48.3%, n = 29 compared with 75.0%, n = 18; p < .05). Our results support the need for a systems approach of institution-wide reforms altering the health care environment and avoiding missed opportunities in IPV screening and referring women to appropriate resources or care. Two of the most frequently reported barriers to asking IPV were structural in nature, pointing to the need for policies that protect privacy and confidentiality. Within the Brazilian context, our research highlights the role of HCPs in the design and implementation of IPV interventions that both strengthen health systems and enable providers to address IPV.
The Indirect Effect of Coping Self-Efficacy on the Relation Between Sexual Violence and PTSD Symptoms
Authors: Mahoney Colin T. , Lynch Shannon M. , Benight Charles C.
Published: October 2019

One in five women experience rape and one in four experience unwanted sexual contact, incurring significant risk of negative psychological outcomes such as posttraumatic stress disorder (PTSD). Given this heightened risk, it is imperative to examine factors that can inhibit the development of PTSD symptoms in response to sexual violence in women. Perceived coping self-efficacy (CSE) is a cognitive appraisal ability utilized to regulate internal and external stressors that arise from traumatic events and is crucial for effective adaptation after traumas such as sexual violence. This study investigated CSE as a potential protective factor against trauma-related psychopathology in female rape survivors. In this study, 518 female undergraduate students ( M age = 22.71 years, SD = 8.33 years; 82.4% Caucasian) completed self-report measures of nonconsensual sexual experiences, CSE, and PTSD symptom severity. Of those, 375 women ( M age = 22.89 years, SD = 6.91 years; 83.7% Caucasian) reported at least one incident of a nonconsensual sexual experience. We hypothesized that CSE would indirectly affect the relationship between sexual violence and PTSD symptom severity, such that CSE would be protective against PTSD symptoms. In line with our hypothesis, there was evidence of a significant indirect effect, 95% confidence interval (CI) = [0.18, 0.44]. This evidence suggests that CSE may be an important protective factor given women’s increased risk of developing PTSD symptoms following sexual violence. Furthermore, this finding suggests that programs targeting the development of CSE may prevent or lessen risk of PTSD symptoms following sexual violence.
Employer Matching Contributions to Section 529 College Savings Plans
Authors: Kilgour John G.
Published: October 2019

The alarming increase of higher education and the resulting growth of student debt in recent years has resulted in a number of employers adopting programs to assist employees with 529 college savings plans. However, the design or adoption of such plans is complicated. They are 529 prepaid tuition plans, educational savings plans or Coverdell Educational Savings Accounts. Many states offer tax deductions, tax credits or grants. Fees and expenses vary significantly among the different types of plans and from state to state as does investment performance. This article examines these matters from the perspective of an employer considering the adoption of a 529 or other college savings plan as an employee benefit.

Published: October 2019

A series of vertical fire suppression experiments on rigid polyurethane (RPU) and flexible polyurethane (FPU) with/without water spray were conducted in a standard chamber. A new video processing method was developed to determine the pyrolysis front position of wind-aided flame. Averaged flame height, carbon monoxide/hydrogen cyanide concentration, view factors, and extinguishing time were determined with operating pressure varying from 0.15 MPa to 0.4 MPa. The experimental study showed that water spray would suppress RPU/FPU fire mainly by fuel surface cooling. Furthermore, the perfect water spray pressure for RPU/FPU fire suppression was 0.3 MPa and the corresponding water application rate was 0.7511 mg/(cm2·s).
Schools, Poverty, and Communities
Authors: Apple Michael W.
Published: October 2019

While some members of the critical education community(ies) may disagree, I think that it is imperative to read and learn from those groups of educators who may not have exactly the same politics as I do. A case in point is the book under discussion in this essay. It focuses on multiple on-the-ground initiatives that seek to provide more responsive schooling through community-school partnerships and through creating an entire range of social, health-related, and educational services that can give us a sense of possibilities. These programs also have the potential to open the door to further democratizing movements and policies that are key elements for critically oriented educational policies and practices. Thus, even though I wanted a more critical understanding of the structural issues involved in why schools often produce inequalities, the book is still a real contribution.
Opting for Private Education: Public Subsidy Programs and School Choice in Disadvantaged Contexts
Authors: Moschetti Mauro Carlos , Verger Antoni
Published: October 2019

Sociological research on school choice has mostly been dominated by studies analyzing the experiences of middle-class families rather than marginalized or minority populations. Drawing on 8 months of ethnographic case study research, this article explores the school choice experiences of disadvantaged families accessing publicly subsidized low-fee private schools (S-LFPSs) in Buenos Aires. We built a bounded-rationality framework to understand how disadvantaged families deal with structural constraints and negotiate their preferences to produce different, but predominantly reflexive rationalities of school preferences. In detailing our findings, we intend to provide “a realistic look at the cognitive and social processes of choice making” while addressing the equity implications of these dynamics—that is, whether S-LFPSs increase educational opportunities for students in economically disadvantaged areas or not—and problematizing the gaps, ambiguities, and enforcement shortcomings of the public subsidy for private schools’ policy.
School Choice Research and Politics with Pierre Bourdieu: New Possibilities
Authors: Yoon Ee-Seul
Published: October 2019

Various sociological perspectives have been applied to facilitate school choice research over the past two decades, as showcased in this 2020 Yearbook of Politics of Education Association. Among them, Pierre Bourdieu’s concepts and theories stand out as a catalyst for the field’s sociological development. My first objective in this article is, thus, to assess the contributions of Bourdieu’s sociological theory to school choice scholarship to date. I review the established and emerging research studies to highlight the significance of Bourdieu’s conceptual system in illuminating the social dynamics of school choice. My second objective in this article is to discuss how Bourdieu’s geographical concerns and concepts have been underutilized in the field. Ultimately, I argue that Bourdieu’s sociospatial concepts can unlock new areas of research and politics by elucidating why and how school choice functions as a mechanism that accentuates social inequality, which is reproduced geographically.
Parental Accountability, School Choice, and the Invisible Hand of the Market
Authors: Potterton Amanda U.
Published: October 2019

I introduce the concept of parental accountability by examining how parents understand and cope with what I characterize are pressures fostered by the long-standing public-school choice market in Arizona. Parental accountability refers to the sensemaking, experiences, and consequences that are related to decision-making in a school choice environment, wherein parents’ feelings about their child’s schooling may be intense, emotionally stressful, malleable, cyclical, and ongoing—not static. I argue that parental accountability is a necessary concept for understanding these reforms. The analysis, based on data collected from a study using ethnographic methods, reveals contradictions between parents’ perceptions of their responsibilities to public institutions and pressures to make private choices. Many parents acknowledged that socioeconomic and racial inequities may be exacerbated in some market-based, public-school choice systems. I show how school choice policies and programs can place unique pressure on parents that they experience as a distinct form of accountability.
Senses of belonging when living in foster care families: Insights from children’s video diaries
Authors: Bengtsson Tea Torbenfeldt , Luckow Stine Tankred
Published: October 2019

This article explores how children living in foster care create senses of belonging across diverse family relationships. It draws on video diaries made by 11 Danish children living in foster care. For the analysis, we have selected two video diaries, made by two girls, aged 12 and 15 years, who live in foster care and have regular contact with their birth family. The girls differ in their senses of belonging but both reflectively negotiate this across their family relationships creating more or less emotional, physical and functional attachments with their foster care and birth families.
The moralization of philanthropy in China: NGOs, voluntarism, and the reconfiguration of social responsibility
Authors: Zhan Yang
Published: October 2019

Neo-liberalism shifts social responsibility to individuals. The practice of neo-liberal governmentality in China confirms this worldwide trend. This is evident when government retreats from the responsibilities of providing social welfare for rural migrant workers and leaves them to privately funded philanthropy programmes. However, the Chinese case also presents an anomaly in that the shifting of responsibilities under neo-liberalism results not only in individualization, but also in mutual obligations created by moralization. This article explores philanthropy programmes in migrant settlements in contemporary Beijing within a larger neo-liberal context. It provides an ethnographic account of the moralization process informed by the culturally specific notion of aixin (爱心), or loving heart. I argue that moralization within philanthropy programmes is crucial in reconfiguring the modes of responsibility in post-socialist China. Here, social obligations and consolidation of old hierarchies and social inequalities go hand in hand with social individualization.
Comparison study of temperature and deformation changes in the femoral component of a novel ceramic-on-ceramic hip resurfacing bearing to a metal standard, using a cadaveric model

Published: October 2019

Hip resurfacing is an attractive alternative to total hip replacement preserving bone and reducing dislocation risk. Recent metal-on-metal designs have caused failure due to metal wear debris. Ceramic implants may mitigate this risk. Temperature increase in periprosthetic bone during cementation can lead to osteonecrosis, while deformation of the component can affect joint lubrication and may increase wear through clamping. Both processes may lead to implant loosening. This study quantifies the temperature and deformation change in a novel ceramic hip resurfacing femoral component compared to a metal standard during cemented implantation in a fresh frozen cadaveric model. Study design and methods Eight femora were prepared from four fresh frozen cadavers. One surgeon experienced in hip resurfacing surgery (J.H.) prepared the femora by reaming. Four ceramic and four metal implants of equal and varying size were cemented in place. Bone and surface temperatures were taken using a probe in the periprosthetic bone and an infrared laser thermometer, respectively. Deformation was measured using a micrometre. Measurements were taken before implantation and every 5-min intervals up to 30 min. The average bone-temperature increment was lower for ceramic heads than for metal heads. Although this difference was not statistically significant, the average bone temperature incremental change in small sizes (42 and 46 mm) was higher than in the large sizes (48 and 50 mm). Most metal heads sustained bearing diameter change that was still near its peak value 30 min after implantation, whereas the ceramic heads suffered a lower diameter change and most of the samples recovered their original diameter 30 min after implantation. Both implants behave similarly, however, a lower temperature rise in bone was observed with ceramic heads. This may lower the risk for thermal damage on periprosthetic bone. The ceramic heads deformed less during surgical implantation. This was not significant.
Effect of orthopedic implants on canine long bone compression stiffness: a combined experimental and computational approach

Published: October 2019

Osteosynthesis for canine long bones is a complex process requiring knowledge of biology, surgical techniques and (bio)mechanical principles. Subject-specific finite element analysis constitutes a promising tool to evaluate the effect of surgical intervention on the global properties of a bone–implant construct, but suffers from a lack of validation. In this study, the biomechanical behavior of 10 canine humeri was compared before and after creation of a 10 mm bone defect stabilized with an eight-hole locking compression plate (Synthes®) and two locking screws on each fragment. The response under compression of both intact and plated samples was measured experimentally and reproduced with a finite element model. The experimental stiffness ratio between plated and intact bone was equal to 0.39 ± 0.06. A subject-specific finite element analysis including density-dependent elasto-plastic material properties for canine bone and automatic generation of orthopedic implants was then conducted to recover these experimental results. The stiffness of intact and plated samples could be predicted, with no significant differences with experimental data. The simulated stiffness ratio between plated and intact canine bone was equal to 0.43 ± 0.03. This study constitutes a first step toward the building of a virtual database of pre-computed cases, aiming at helping the veterinary surgeons to make decisions regarding the most suited orthopedic solution for a given dog and a given fracture.
Sustainable Water Resources Management: Issues and Principles of Water Governance in the Okavango Delta, Botswana
Authors: Gondo Reniko , Kolawole Oluwatoyin D.
Published: October 2019

In the recent times, there is an increased awareness about the importance of water management as population growth, new technologies, increased food consumption, land use and economic activities, among others, continue to exacerbate competition among water users in their bid to access natural resources. Thus, water governance encompasses the allocation and management of aquatic resources within the context of a multilayered, competing demand for water resources. Employing a critical review of relevant literature and guided by the legal pluralism conceptual framework and situated within the Dublin water management principles, this article examines key principles and pertinent issues in sustainable water resources management in the Okavango Delta, Botswana; the delta is widely recognized as a wetland of international significance. Findings reveal that demographic and socio-economic factors such as age, education, religion, culture, gender and income play significant roles in household water management decision making. The results also show that although the water legislative environment in Botswana is characterized by outdated Water Acts, efforts and commitment from the government are underway to revise these Acts. This article argues that whilst water research scholars and policymakers continue to make advocacy for water governance at different levels, the local-level water governance needs to be accorded more priority in rural areas in Botswana.
Modeling and analysis of spiral actuators by exact geometry piezoelectric solid-shell elements
Authors: Kulikov GM , Plotnikova SV , Carrera E
Published: October 2019

An exact geometry four-node piezoelectric solid-shell element through the sampling surfaces formulation is proposed. The sampling surfaces formulation is based on choosing inside the shell N – 2 sampling surfaces parallel to the middle surface and located at Chebyshev polynomial nodes to introduce the displacements and electric potentials of these surfaces as fundamental shell unknowns. The bottom and top surfaces are also included into a set of sampling surfaces. Such choice of unknowns with the use of Lagrange polynomials of degree N – 1 in the through-the-thickness interpolations of displacements, strains, electric potential, and electric field yields a robust piezoelectric shell formulation. To implement efficient analytical integration throughout the solid-shell element, the extended assumed natural strain method is employed. The developed hybrid-mixed four-node piezoelectric solid-shell element is based on the Hu-Washizu variational principle and shows the excellent performance for coarse mesh configurations. It can be useful for the 3D stress analysis of piezoelectric shells with variable curvatures, in particular for the modeling and analysis of spiral actuators.
Posthumanist and Postcolonial Possibilities for Outdoor Experiential Education
Authors: Riley Kathryn
Published: October 2019

Background: Teaching and learning in outdoor experiential education is often conducted on lands with troubled histories of settler colonialism. This calls for new and creative forms of socioecological responsibility to attend to human supremacism and exceptionalism that marginalizes, exploits, dominates, and objectifies Other(s) in these Anthropocene times. Purpose: Through posthumanist philosophy (re)conceptualizing Western binary logics, this article explores possibilities for postcolonial land ethics in outdoor experiential education to address past, present, and future socioecological injustices and threats. Methodology/Approach: Adopting new materialist methodologies, this article examines affective materiality emerging from a series of multisensory researcher/teacher enactments, as set within pedagogies attuning-with land with a Grade 4/5 class in Canada. Findings/Conclusions: The affective materiality of sense-making in the researcher/teacher enactments provided opportunities to challenge discursively positioned land ethics, suggesting a transforming-with Other(s) through relationally co-constituted existences. Implications: Understanding that no separate and discrete worldviews exist in which individuals act through autonomous agency, but that worlding emerges through relational agency, teaching, and learning in outdoor experiential education can generate an intrinsic sense of responsibility to attend to more equitable relationships with Other(s) for/with/in these Anthropocene times.
I Am As Normal As Everyone Now. . . : Examination of Experiences of Patients Undergoing Bariatric Surgery According to Roy’s Adaptation Model: A Qualitative Study
Authors: Kabu Hergül Filiz , Özbayır Türkan
Published: October 2019

The aim of this study is to examine experiences of patients undergoing bariatric surgery according to Roy’s adaptation model (RAM). This is a qualitative study with a phenomenological design. The sample included patients undergoing bariatric surgery ( N: 32). Of all the patients 84.37% were female and 59.38% were married. According to results of the content analysis, adaptive patient behavior was described by the themes “My life has changed”, Everything is beautiful” “I can cope” and “Luckily, I have them” and their nonadaptive behavior was described by the themes “What if I cannot succeed”, “Bad news” and “So many people, so many views”. Patients having bariatric surgery experience various difficulties in adapting to their life and bodies, but the surgery leads to improvements in their body image, social life, personal relationships, and maintenance of roles. However, some patients can be afraid of postoperative complications and experience anxiety about regaining weight.

Published: October 2019

A cross-sectional study was conducted to investigate the association between body composition parameters as well as body mass index (BMI), and dietary energy density in a population of 538 young adults. Fat mass, fat mass percent, fat-free mass, and visceral fat were measured using a body composition analyzer. Daily energy intake was assessed using a 72-hr diet recall, and dietary energy density was calculated. Significant differences in dietary energy density among underweight, normal-weight and overweight/obesity young adults were identified ( M = 1.42, SD = 0.26 vs. M = 1.52, SD = 0.46 vs. M = 1.66, SD = 0.53, p = .002). Dietary energy density was associated with BMI (β = .961; CI 95% = 0.335, 1.586; p = .0030), fat mass percent (β = 1.921; CI 95% = 0.707, 3.135; p = .002), and fat mass (β = 2.146; CI 95% = 0.827, 3.466; p = .001). Dietary energy density might be considered as an important aspect in the obesity nutritional education programs in young people.

Published: October 2019

Transcranial direct current stimulation (tDCS) can shift neuronal membrane excitability by applying a weak slow electric current to the brain through the scalp. Attendant electroencephalography (EEG) can provide valuable information about the tDCS mechanisms. This study investigated the effects of anodal tDCS on parietal cortex and cerebellum activity to reveal possible modulation of spontaneous oscillatory brain activity. Timing of the tDCS priming protocol in relation to the intervention especially with respect to bimanual coordination task was also studied. EEG activity was measured in 120 healthy participants before and after sessions of anodal stimulation of the parietal cortex and cerebellum to detect the tDCS-induced alterations. Variations of the delta, theta, alpha, beta, and sensorimotor rhythm (SMR) power bands were analyzed using a MATLAB program. The results showed that anodal parietal and cerebellar tDCS cause changes in brain wave frequencies. They also showed an increase in alpha, beta, and SMR power bands during stimulation sessions for during stimulation parietal group ( p ≤ .01). Also, theta, alpha, beta, and SMR power bands were increased in during stimulation cerebellum group in stimulation sessions and 48 h later ( p ≤ .01). Moreover, the results revealed that the tDCS intervention led to a variety of activations in some areas of the brain. Altogether, the cerebellar tDCS during motor task had a significant improvement in off-line learning.
Emotion as an emergent phenomenon of the neurocomputational energy regulation mechanism of a cognitive agent in a decision-making task
Authors: Kirtay Murat , Vannucci Lorenzo , Albanese Ugo , Laschi Cecilia , Oztop Erhan , Falotico Egidio
Published: October 2019

Biological agents need to complete perception-action cycles to perform various cognitive and biological tasks such as maximizing their wellbeing and their chances of genetic continuation. However, the processes performed in these cycles come at a cost. Such costs force the agent to evaluate a tradeoff between the optimality of the decision making and the time and computational effort required to make it. Several cognitive mechanisms that play critical roles in managing this tradeoff have been identified. These mechanisms include adaptation, learning, memory, attention, and planning. One of the often overlooked outcomes of these cognitive mechanisms, in spite of the critical effect that they may have on the perception-action cycle of organisms, is “emotion.” In this study, we hold that emotion can be considered as an emergent phenomenon of a plausible neurocomputational energy regulation mechanism, which generates an internal reward signal to minimize the neural energy consumption of a sequence of actions (decisions), where each action triggers a visual memory recall process. To realize an optimal action selection over a sequence of actions in a visual recalling task, we adopted a model-free reinforcement learning framework, in which the reward signal—that is, the cost—was based on the iteration steps of the convergence state of an associative memory network. The proposed mechanism has been implemented in simulation and on a robotic platform: the iCub humanoid robot. The results show that the computational energy regulation mechanism enables the agent to modulate its behavior to minimize the required neurocomputational energy in performing the visual recalling task.
School Nursing for the 21st Century: Assessing Scope of Practice in the Current Workforce
Authors: Davis Diane , Maughan Erin D. , White Krista A. , Slota Margaret
Published: October 2019

A gap analysis was used to examine the scope of school nursing practice in the United States. An investigator-developed 39-item self-assessment survey of scope of school nursing practice was modified from an existing validated tool, organized around the five principles of the National Association of School Nurses’ Framework: Standards of Practice, Quality Improvement, Care Coordination, Community/Public Health, and Leadership and also explored barriers to practice. The survey was sent to a national convenience sample of practicing school nurses. The survey was completed by 3,108 practicing school nurses. Gaps were identified for all principles and were greatest for Quality Improvement and Community/Public Health practice. All practice items were rated more important than the ability to practice that item ( p < .001). Self-identified barriers including workload, school/district expectations, and state regulations accounted for significant variances in practice across four of five principles ( p < .05, p < .001). Recommendations include support for population-focused evidence–based school nursing practice.

Published: October 2019

One common complication after joint arthroplasty is venous thromboembolism (VTE). Therefore, it is essential to measure the changes in coagulation and fibrinolysis in order to predict VTE among patients who underwent joint arthroplasty. This study aimed to identify potential useful biomarkers for prognosing to VTE. This was a prospective cohort study enrolling 83 patients who underwent joint arthroplasty. The levels of d-dimer, thrombin–antithrombin complex (TAT), plasmin–α2-antiplasmin complex (PIC), soluble thrombomodulin, and tissue plasminogen activator inhibitor complex were measured on day 0 (before surgery) and days 1, 3, and 6 after surgery. Ultrasound examination was used to diagnose VTE on preoperative day 0 and postoperative day 6. A total of 35 patients developed VTE after surgery. Patients with VTE exhibited significantly higher levels of d-dimer and TAT on postoperative days 3 and 6 (all P < .05). The area under curves (AUC) of receiver operating characteristic (ROC) were 0.65 and 0.68 and 0.68 and 0.74 for d-dimer and TAT levels on postoperative days 3 and 6, respectively. The level of TAT/PIC ratio on postoperative day 6 was significantly increased among patients with VTE compared to non-VTE patients ( P < .0001). In addition, the AUC of ROC, cutoff level, sensitivity, specificity, positive-predictive value, and negative-predictive value of TAT/PIC ratio were 0.78, 4.03 ng/TU, 97.14%, 33.33%, 51.52%, and 94.12%, respectively. The high sensitivity and negative predictive value of TAT/PIC ratio make it a potential prognostic index for diagnosing VTE during the early phase of postoperative joint arthroplasty.
Striking a Balance: A National Assessment of Economic Development Incentives
Authors: Donegan Mary , Lester T. William , Lowe Nichola
Published: October 2019

The use of incentive packages has intensified as local governments compete for new plants and corporate relocations and as private firms increasingly demand a deal. While incentives promise jobs and tax revenue, scholars and practitioners criticize their high cost and limited accountability. Through a comparison of matched establishments, this article explores how governmental incentive-granting strategy impacts incentive performance. We examine the overall impact of incentives and whether incentives granted to smaller firms perform better. Using economic development budget data, we also assess the state’s overall approach to economic development to determine which strategies are prioritized through funding. By showing that incentivized firms fail to create more jobs than matched controls, our analysis casts doubt on claims that “but for” incentives job creation would not occur. Still, our findings suggest that states are smarter in their incentive use when they strike a balance between recruiting industry and supporting “homegrown” businesses and technology.
Beyond the crazy ex-girlfriend: Drawing the contours of a radical vulnerability
Authors: De Graeve Katrien
Published: October 2019

In this article, I reflect on the process of understanding and my strategies of reporting in the context of a three-year ethnographic study on non-monogamous sex and relationships in Belgium, which included interviews and participant observation in various dating sites and in support groups for people in consensual non-monogamous relationships. I draw the contours of what a research ethics that creates space for the researcher's embodied learning, and learning through sexual-intimate relationships in particular, might look like, centralizing the concept of vulnerability. An ethics of intersubjective vulnerability not only has the potential to constitute an epistemological position from which to conduct critical analyses that aims at producing multidimensional and embodied understanding of power relations, it also constitutes a space of political contestation and a position from which to start to envision alternative possibilities to the neoliberal values that have pervaded society.
Forgotten lives: Trans older adults living with dementia at the intersection of cisgenderism, ableism/cogniticism and ageism
Authors: Baril Alexandre , Silverman Marjorie
Published: October 2019

There is little research at the international level to help us understand the experiences and needs of trans people living with dementia, despite population aging and the growing numbers of trans people including the first cohort of trans older adults. There is a need to understand the widespread barriers, discrimination and mistreatment faced by trans people in the health and social service system, and the fears trans people express about aging and dementia. Anecdotal evidence from the scarce literature on the topic of LGBTQ populations and dementia suggest that cognitive changes can impact on gender identity. For example, trans older adults with dementia may forget they transitioned and reidentify with their sex/gender assigned at birth or may experience ‘gender confusion.’ This raises crucial questions, for example regarding practices related to pronouns, care to the body (shaving, hair, clothes, etc.), social gendered interactions, health care (continuing or not hormonal therapy) and so on. This article fills a gap in current literature by offering a first typology of responses offered by academics who analyzed the topic of dementia and gender identity, to trans older adults with dementia who may be experiencing ‘gender confusion,’ namely: (1) a gender neutralization approach; (2) a transaffirmative stable approach; and (3) a trans-affirmative fluid approach. After providing critical reflections regarding each approach, we articulate the foundations of a fourth paradigm, rooted in an interdisciplinary dialogue regarding the interlocking systems of oppression faced by trans older adults with dementia, namely ageism, ableism/sanism, and cisgenderism.

Exercise-induced bronchoconstriction (EIB) is a sign of uncontrolled childhood asthma and classically occurs after exercise. Recent research shows that EIB frequently starts during exercise, called breakthrough-EIB (BT-EIB). It is unknown whether this more severe type of EIB forces children to adapt their physical activity (PA) pattern in daily life. Therefore, this pilot study aims to investigate daily life PA (amount, intensity, duration, and distribution) in children with BT-EIB, ‘classic’ EIB, and without EIB. A Fitbit Zip activity tracker was used for one week to objectively measure daily life PA at one-minute intervals. Thirty asthmatic children participated. Children with BT-EIB were less physically active compared to children without EIB (respectively 7994 and 11,444 steps/day, p = .02). Children with BT-EIB showed less moderate-to-vigorous PA compared to the children without (respectively 117 and 170 minutes/day, p = .02). Children with EIB (both BT and classic) had significant shorter bouts of activity and a less stretched distribution of bout lengths compared to the non-EIB group (all p < .05). These results emphasize a marked association between EIB severity and PA patterns in daily life, stressing the need for a thorough clinical evaluation of exercise-induced symptoms in childhood asthma.
In their shoes? Categorizing identities and creating citizens in refugee reality TV

The so-called migration crisis in Europe is not only covered by serious informative genres such as news and documentaries, but has also been the topic of entertainment genres such as reality TV. This article focuses on two cases of European ‘refugee’ reality TV in which European participants embark on a ‘reversed’ refugee journey: from the Netherlands and Germany, respectively, to war-torn countries in Africa and the Middle East. Despite the shows’ claims to fulfill an important function of educating the broader public about the hardship and plight experienced by refugees in Europe, the construction and conception of collective cultural identities in these shows warrants closer analysis. Through an interpretative textual analysis of the series, we investigate how civil belonging is mapped and constructed by the series as a range of different subject positions on refugees and civic responsibility toward refugees. This study problematizes the manner in which a plurality of voices is accommodated in contemporary European liberal democratic society and how cultural forms such as reality TV function normatively as a technology of citizenship.
Situating the life story narratives of aging immigrants within a structural context: the intersectional life course perspective as research praxis
Authors: Brotman Shari , Ferrer Ilyan , Koehn Sharon
Published: October 2019

Research on racialized older immigrants does not fully acknowledge the interplay between the life course experiences of diverse populations and the structural conditions that shape these experiences. Our research team has developed the intersectional life course perspective to enhance researchers’ capacity to take account of the cumulative effects of structural discrimination as people experience it throughout the life course, the meanings that people attribute to those experiences, and the implications these have on later life. Here we propose an innovative methodological approach that combines life story narrative and photovoice methods in order to operationalize the intersectional life course. We piloted this approach in a study of the everyday stories of aging among diverse immigrant older adults in two distinct Canadian provinces with the goals of enhancing capacity to account for both context and story and engaging with participants and stakeholders from multiple sectors in order to influence change.
Liberalism, commodification, and justice
Authors: Panitch Vida
Published: October 2019

Anti-commodification theorists condemn liberal political philosophers for not being able to justify restricting a market transaction on the basis of what is sold, but only on the basis of how it is sold. The anti-commodification theorist is correct that if this were all the liberal had to say in the face of noxious markets, it would be inadequate: even if everyone has equal bargaining power and no one is misled, there are some goods that should not go to the highest bidder. In this paper, I respond to the anti-commodification critique of liberalism by arguing that the political liberal has the wherewithal to account not only for the conditions under which goods should not be sold, but also for what kinds of goods should not be for sale in a market economy. The political liberal can appeal to a principle of equal basic rights, and to one of sufficiency in basic needs and the social bases of self-respect, I argue, to account for what’s problematic about markets in civic goods, necessary goods, and physical goods including body parts and intimate services.
Can Conversation-Based Intervention Using Speech-Generating Devices Improve Language in Children With Partially Intelligible Speech?
Authors: Luckins Jessie M. , Clarke Michael T.
Published: October 2019

Children with partially intelligible speech and language difficulties are often provided with speech-generating devices (SGDs) to support their spoken communication. However, little is known about how SGDs can be used best to facilitate language development. This study evaluated the effects of a conversation-based intervention using SGDs, on the rate of expressive clause production in children with speech that is partially intelligible (SPI). A multiple probe across participants design was used to evaluate intervention with four children aged 8 to 10 years. Following baseline monitoring, the children received language-focused intervention involving adult recasting, SGD modeling, and prompting to repair. Participants showed increases in their rate, complexity and length of clause use. Gains were sustained and generalized. Intervention using conversation, recasting, and SGD modeling can increase clause production and grammaticality of children with SPI.
Stability evaluation of high-order splitting method for incompressible flow based on discontinuous velocity and continuous pressure

In this work, we deal with high-order solver for incompressible flow based on velocity correction scheme with discontinuous Galerkin discretized velocity and standard continuous approximated pressure. Recently, small time step instabilities have been reported for pure discontinuous Galerkin method, in which both velocity and pressure are discretized by discontinuous Galerkin. It is interesting to examine these instabilities in the context of mixed discontinuous Galerkin–continuous Galerkin method. By means of numerical investigation, we find that the discontinuous Galerkin–continuous Galerkin method shows great stability at the same configuration. The consistent velocity divergence discretization scheme helps to achieve more accurate results at small time step size. Since the equal order discontinuous Galerkin–continuous Galerkin method does not satisfy inf-sup stability requirement, the instability for high Reynolds number flow is investigated. We numerically demonstrate that fine mesh resolution and high polynomial order are required to obtain a robust system. With these conclusions, discontinuous Galerkin–continuous Galerkin method is able to achieve high-order spatial convergence rate and accurately simulate high Reynolds flow. The solver is tested through a series of classical benchmark problems, and efficiency improvement is proved against pure discontinuous Galerkin scheme.
