Music self-concept and self-esteem formation in adolescence: A comparison between individual and normative models of importance within a latent framework
Authors: Scalas L. Francesca , Marsh Herbert W. , Vispoel Walter , Morin Alexandre J. S. , Wen Zhonglin
Published: October 2016

We examined the possible effects of six dimensions of music self-concept on determination of self-esteem, through the application of models based on individual and normative-group importance. Previous studies have supported the individual model of importance in narrowly defined self-domains such as spiritual self-concept that might be unimportant for most people, but very important for some people. However, results from more recent studies of spiritual, academic, and physical self-concepts involving latent variable methodologies support the normative-group model. Here, we extended the use of latent variable methods to music self-concept using a sample of 512 junior high students (11–16 years old). Our results for music-reading skills supported the individual importance model rather than the normative-group importance model. Additional results revealed that singing, instrument playing, and the importance of instrument playing had direct rather than interactive linkages with self-esteem. Collectively, these results highlight differential effects of performance (singing, instrument playing) and knowledge (reading) on self-esteem, and imply that strategies to enhance self-esteem may vary within different domains of music instruction and participation. At a more general level, the findings together with those from previous studies indicate that interconnections between specific and global aspects of self-concept vary across domains and are more complex than previously thought.
Search engine imaginary: Visions and values in the co-production of search technology and Europe
Authors: Mager Astrid
Published: October 2016

This article discusses the co-production of search technology and a European identity in the context of the EU data protection reform. The negotiations of the EU data protection legislation ran from 2012 until 2015 and resulted in a unified data protection legislation directly binding for all European member states. I employ a discourse analysis to examine EU policy documents and Austrian media materials related to the reform process. Using the concept ‘sociotechnical imaginary’, I show how a European imaginary of search engines is forming in the EU policy domain, how a European identity is constructed in the envisioned politics of control, and how national specificities contribute to the making and unmaking of a European identity. I discuss the roles that national technopolitical identities play in shaping both search technology and Europe, taking as an example Austria, a small country with a long history in data protection and a tradition of restrained technology politics.
A few good (wo)men? Gender diversity on Australian boards
Authors: Strydom Maria , Au Yong Hue Hwa , Rankin Michaela
Published: October 2016

This article examines the relation between gender diversity and earnings quality for Australian firms from 2005 to 2013. We draw on the work of Kanter, highlighting the importance of the proportion of women on the board when measuring diversity. We show that all-male and skewed boards have lower earnings quality while that of tilted and balanced boards is higher. In addition, a critical mass of women is achieved when some 30% of directors are females. Performance and risk do not influence the relation. We contribute by presenting evidence supporting critical mass theory. Furthermore, our work adds to the recent debate on whether the association between gender diversity and earnings quality is U-shaped, rather than linear. Our results have implications for regulation and practice. We identify the need for a critical mass of women, rather than tokens, to enhance earnings quality.
Muslim religiosity, generational cohorts and buying behaviour of Islamic financial products
Authors: Sharma Revti-Raman , Newaz Farhana T , Fam Kim-Shyan
Published: October 2016

This study examines the effects of the interplay between various aspects of religiosity, generational cohorts and buying attitude on Muslim consumers’ purchase intention of Islamic financial products. Based on data collected from 1263 Muslim consumers in Bangladesh, the findings broadly support the proposed conceptual model that buying attitude acts as a mechanism that transforms religiosity dimensions of Muslims into purchase intention and that the Muslim religiosity–buying attitude–purchase intention relationship is moderated by generational cohorts. The unbundling of the religiosity construct provides a deeper understanding of how the mediating (buying attitude) and moderating (generational cohorts) relationships vary across various religiosity dimensions.
Research data services

Published: October 2016

The paper reports on an exploratory study of researchers’ needs for effective research data management at two Swedish universities, conducted in order to inform the ongoing development of research data services. Twelve researchers from diverse fields have been interviewed, including biology, cultural studies, economics, environmental studies, geography, history, linguistics, media and psychology. The interviews were structured, guided by the Data Curation Profiles Toolkit developed at Purdue University, with added questions regarding subject metadata. The preliminary analysis indicates that the research data management practices vary greatly among the respondents, and therefore so do the implications for research data services. The added questions on subject metadata indicate needs of services guiding researchers in describing their datasets with adequate metadata.
Modifying researchers’ data management practices
Authors: Hickson Susan , Poulton Kylie Ann , Connor Maria , Richardson Joanna , Wolski Malcolm
Published: October 2016

Data is the new buzzword in academic libraries, as policy increasingly mandates that data must be open and accessible, funders require formal data management plans, and institutions are implementing guidelines around best practice. Given concerns about the current data management practices of researchers, this paper reports on the initial findings from a project being undertaken at Griffith University to apply a conceptual (A-COM-B) framework to understanding researchers’ behaviour. The objective of the project is to encourage the use of institutionally endorsed solutions for research data management. Based on interviews conducted by a team of librarians in a small, social science research centre, preliminary results indicate that attitude is the key element which will need to be addressed in designing intervention strategies to modify behaviour. The paper concludes with a discussion of the next stages in the project, which involve further data collection and analysis, the implementation of targeted strategies, and a follow-up activity to assess the extent of modifications to current undesirable practices.
The Effect of the “Zero Tolerance for Head Contact” Rule Change on the Risk of Concussions in Youth Ice Hockey Players
Authors: Krolikowski Maciej P. , Black Amanda M. , Palacios-Derflingher Luz , Blake Tracy A. , Schneider Kathryn J. , Emery Carolyn A.
Published: October 2016

Background:

Ice hockey is a popular winter sport in Canada. Concussions account for the greatest proportion of all injuries in youth ice hockey. In 2011, a policy change enforcing “zero tolerance for head contact” was implemented in all leagues in Canada.

Purpose:

To determine if the risk of game-related concussions and more severe concussions (ie, resulting in >10 days of time loss) and the mechanisms of a concussion differed for Pee Wee class (ages 11-12 years) and Bantam class (ages 13-14 years) players after the 2011 “zero tolerance for head contact” policy change compared with players in similar divisions before the policy change.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

The retrospective cohort included Pee Wee (most elite 70%, 2007-2008; n = 891) and Bantam (most elite 30%, 2008-2009; n = 378) players before the rule change and Pee Wee (2011-2012; n = 588) and Bantam (2011-2012; n = 242) players in the same levels of play after the policy change. Suspected concussions were identified by a team designate and referred to a sport medicine physician for diagnosis. Incidence rate ratios (IRRs) were estimated based on multiple Poisson regression analysis, controlling for clustering by team and other important covariates and offset by game-exposure hours. Incidence rates based on the mechanisms of a concussion were estimated based on univariate Poisson regression analysis.

Results:

The risk of game-related concussions increased after the head contact rule in Pee Wee (IRR, 1.85; 95% CI, 1.20-2.86) and Bantam (IRR, 2.48; 95% CI, 1.17-5.24) players. The risk of more severe concussions increased after the head contact rule in Pee Wee (IRR, 4.12; 95% CI, 2.00-8.50) and Bantam (IRR, 7.91; 95% CI, 3.13-19.94) players. The rates of concussions due to body checking and direct head contact increased after the rule change.

Conclusion:

The “zero tolerance for head contact” policy change did not reduce the risk of game-related concussions in Pee Wee or Bantam class ice hockey players. Increased concussion awareness and education after the policy change may have contributed to the increased risk of concussions found after the policy change.
The Closing Door
Authors: Paino Maria , Boylan Rebecca L. , Renzulli Linda A.
Published: October 2016

Charter schools are promoted by policy makers and advocates as a way to reduce educational inequality. Charter schools tend to enroll higher proportions of black students than do traditional public schools. However, the accountability function of charter schools means that these schools are also more likely to close than traditional public schools. A high incidence of closure can lead to educational instability with students moving in and out of charter schools and traditional schools. We use critical race theory to build on prior work, examining the factors that may promote or constrain charter school closure. Specifically, we ask, how do the racial demographics of a charter school affect its likelihood of closure? Our findings reveal that as the proportion of black students in a charter school increases, so too does its likelihood of closings. Our work suggests that the promotion of charter schools as avenues of racial equity may be misleading.
Modeling and experimental investigation of out-of-plane deformation on mechanical performance of composites manufactured by ATL
Authors: Chu Qiyi , Li Yong , Xiao Jun , Huan Dajun , Chen Xiaodong
Published: October 2016

The change of mold normal curvature along the trajectory may result in out-of-plane waviness during the automated laying process, on which the layup speed and temperature would have an effect. A new parameter, deformation rate, was defined by combining the effect of mold curvature change rate and layup speed. A predicting model was proposed based on the fiber waviness and interlaminar sliding model to calculate the relationship between stiffness retention and the layup process parameters, including deformation rate and temperature. An experimental study on the effect of different deformation parameters on the tensile performance of composites was carried out based on a new manufacturing method of plated specimens with different levels of waviness by means of a four-point bending fixture. The experimental results showed that when the deformation temperature increases from 20℃ to 80℃, the tensile strength increases first and then decreases while the tensile module keeps increasing. While the deformation rate decreases from 0.40 to 0.04 mm−1/s, both tensile strength and module showed an increasing trend. The predicting model being validated by experimental results can be utilized to optimize the layup process parameter to satisfy the quality and efficiency requirements.
Psychometric Assessment of the Short Grit Scale Among Chinese Adolescents
Authors: Li Jingguang , Zhao Yajun , Kong Feng , Du Shuailing , Yang Suyong , Wang Song
Published: October 2016

This study sought to validate the Short Grit Scale (Grit-S), an instrument that measures perseverance and passion for long-term goals, among Chinese high school students. Confirmatory factor analyses revealed that the scale retains the two-factor structure of the original scale. The scale demonstrated satisfactory internal consistency and test–retest reliability. Evidence for construct validity was found in relation to the Big Five personality traits, self-control, and IQ. Evidence for criterion validity was found via the observation that grit explained unique variance in academic performance. Together, the Grit-S is a sound measure of grit among Chinese adolescents.
Frédéric Le Play and 19th-century vision machines
Authors: Freemantle Harry
Published: October 2016

An early proponent of the social sciences, Frédéric Le Play, was the occupant of senior positions within the French state in the mid- to late 19th century. He was writing at a time when science was ascending. There was for him no doubt that scientific observation, correctly applied, would allow him unmediated access to the truth. It is significant that Le Play was the organizer of a number of universal expositions because these expositions were used as vehicles to demonstrate the ascendant position of western civilization. The fabrication of linear time is a history of progress requiring a vision of history analogous to the view offered the spectator at a diorama. Le Play employed the design principles and spirit of the diorama in his formulations for the social sciences, and L’Exposition Universelle of 1867 used the technology wherever it could. Both the gaze of the spectators and the objects viewed are part and products of the same particular and unique historical formation. Ideas of perception cannot be separated out from the conditions that make them possible. Vision and its effects are inseparable from the observing subject who is both a product of a particular historical moment and the site of certain practices.
Bayesian method to solve the early failure period of numerical control machine tool
Authors: Yang Zhaojun , He Jialong , Wang Jian , Li Guofa , Tian Hailong , Du Xuejiao , Kan Yingnan
Published: October 2016

The hazard rate curve of the numerical control machine tool is a bathtub curve. The change point between the early failure period and the random failure period of the curve is difficult to obtain with a small data sample; thus, a Bayesian method is proposed. A method to build the prior distributions of the Weibull parameters is developed, which integrates the multi-source prior information of the target numerical control machine tool and the reference numerical control machine tool. The Markov chain Monte Carlo method is adopted to calculate the estimators of the Weibull parameters corresponding to each failure, which solves the problem of the absence of an analytical solution. The total working time of the numerical control machine tool when the estimator of the shape parameter is equal to 1 is estimated by taking the estimator of the shape parameter as the function of time. As a result, the change point and the early failure period are obtained. Comparison result shows that the result obtained through an existing change point solving method with a large dataset is close to the result generated through the proposed method with a small dataset. The change point and the early failure period obtained with the proposed method can be used to guide the early failure test and to design a rational maintenance strategy, which are of vital engineering significance.
A web-based knowledge management system integrating Western and Traditional Chinese Medicine for relational medical diagnosis
Authors: Herrera-Hernandez Maria C , Lai-Yuen Susana K , Piegl Les A , Zhang Xiao
Published: October 2016

This article presents the design of a web-based knowledge management system as a training and research tool for the exploration of key relationships between Western and Traditional Chinese Medicine, in order to facilitate relational medical diagnosis integrating these mainstream healing modalities. The main goal of this system is to facilitate decision-making processes, while developing skills and creating new medical knowledge. Traditional Chinese Medicine can be considered as an ancient relational knowledge-based approach, focusing on balancing interrelated human functions to reach a healthy state. Western Medicine focuses on specialties and body systems and has achieved advanced methods to evaluate the impact of a health disorder on the body functions. Identifying key relationships between Traditional Chinese and Western Medicine opens new approaches for health care practices and can increase the understanding of human medical conditions. Our knowledge management system was designed from initial datasets of symptoms, known diagnosis and treatments, collected from both medicines. The datasets were subjected to process-oriented analysis, hierarchical knowledge representation and relational database interconnection. Web technology was implemented to develop a user-friendly interface, for easy navigation, training and research. Our system was prototyped with a case study on chronic prostatitis. This trial presented the system’s capability for users to learn the correlation approach, connecting knowledge in Western and Traditional Chinese Medicine by querying the database, mapping validated medical information, accessing complementary information from official sites, and creating new knowledge as part of the learning process. By addressing the challenging tasks of data acquisition and modeling, organization, storage and transfer, the proposed web-based knowledge management system is presented as a tool for users in medical training and research to explore, learn and update relational information for the practice of integrated medical diagnosis. This proposal in education has the potential to enable further creation of medical knowledge from both Traditional Chinese and Western Medicine for improved care providing. The presented system positively improves the information visualization, learning process and knowledge sharing, for training and development of new skills for diagnosis and treatment, and a better understanding of medical diseases.
Biomechanical analysis of the cephalomedullary nail versus the trochanteric stabilizing plate for unstable intertrochanteric femur fractures

Published: October 2016

Unstable intertrochanteric fractures are commonly treated with a cephalomedullary nail due to high failure rates with a sliding hip screw. The Omega3 Trochanteric Stabilizing Plate is a relatively new device that functions like a modified sliding hip screw with a proximal extension; however, its mechanical properties have not been evaluated. This study biomechanically compared a cephalomedullary nail, that is, Gamma3 Nail against the Omega3 plate. Unstable intertrochanteric fractures were created in 24 artificial femurs. Experimental groups were as follows: Nail (i.e. Gamma3 Nail) (n = 8), Plate A (i.e. Omega3 plate with four distal non-locking screws and no proximal locking screws) (n = 8), Plate B (i.e. Plate A plus five proximal locking screws) (n = 8), Plate C (i.e. Omega3 plate with three distal locking screws and no proximal locking screws) (n = 8), and Plate D (i.e. Plate C plus five proximal locking screws) (n = 8). All specimens were stiffness tested, while the Nail and Plate D groups were also strength tested. For lateral bending, Plate B was less stiff than the Nail (p = 0.001) and Plate A (p = 0.009). For torsion, Plate A was less stiff than Plate D (p = 0.020). For axial compression, the Nail was less stiff than Plate A (p = 0.036) and Plate B (p = 0.008). Axial strength for the Nail (5014 ± 308 N) was 66% higher than the Plate D construct (2940 ± 411 N) (p < 0.001). All Nails failed by partial or complete cutout through the femoral head and neck, but Plate D failed by varus collapse and deformation of the lag screw. When the cephalomedullary nail is clinically contra-indicated, this study supports the use of the Omega3 plate, since it had similar stiffness in three test modes to the Gamma3 Nail, but had lower strength. Stability of Omega3 plate constructs was not improved with locked fixation proximally or distally.
Dolutegravir 50 mg thrice weekly plus atazanavir 400 mg daily in a long-term virologically suppressed HIV-infected patient

Published: October 2016

Highly active antiretroviral therapy (HAART) has changed the natural course of HIV infection. However, the toxicities associated with long-term use of nucleoside reverse transcriptase inhibitors (NRTIs) have led to the assessment of dual-therapy approaches with less toxicity. Atazanavir and dolutegravir have antiviral potency, tolerability and favourable metabolic profile. In suppressed HIV-infected patients, with NRTIs-related toxicity effects, the association of atazanavir and dolutegravir, favoured by their positive pharmacokinetics interaction, could be used as ‘maintenance’ antiretroviral therapy. We report a case report about one HIV-infected patient, on HAART and with a persistent suppression of HIV RNA, switched to dolutegravir 50 mg three times weekly plus atazanavir 400 mg once daily, as ‘maintenance antiretroviral therapy’, with persistence of viral suppression.
Henderson and Meyer in correspondence: a transatlantic history of dynamic psychiatry, 1908–29
Authors: Morrison Hazel
Published: October 2016

Charting a transatlantic movement of so-called ‘dynamic psychiatry’ during the early twentieth century, this paper reads against the grain of established historiographies. Comparing biographical and autobiographical sources with contemporary correspondence, a history is told which considers the evolution of psychiatric knowledge and clinical practices ‘from below’. Revealing a period and place when a ‘dynamic’ counter-culture challenged the established materialist views of Scottish psychiatry, the longevity of this challenge is considered in the concluding paragraphs.
Dynamic longitudinal discriminant analysis using multiple longitudinal markers of different types
Authors: Hughes David M , Komárek Arnošt , Czanner Gabriela , Garcia-Fiñana Marta
Published: October 2016

There is an emerging need in clinical research to accurately predict patients’ disease status and disease progression by optimally integrating multivariate clinical information. Clinical data are often collected over time for multiple biomarkers of different types (e.g. continuous, binary and counts). In this paper, we present a flexible and dynamic (time-dependent) discriminant analysis approach in which multiple biomarkers of various types are jointly modelled for classification purposes by the multivariate generalized linear mixed model. We propose a mixture of normal distributions for the random effects to allow additional flexibility when modelling the complex correlation between longitudinal biomarkers and to robustify the model and the classification procedure against misspecification of the random effects distribution. These longitudinal models are subsequently used in a multivariate time-dependent discriminant scheme to predict, at any time point, the probability of belonging to a particular risk group. The methodology is illustrated using clinical data from patients with epilepsy, where the aim is to identify patients who will not achieve remission of seizures within a five-year follow-up period.
Patients’ moral views on coercion in mental healthcare
Authors: Norvoll Reidun , Pedersen Reidar
Published: October 2016

Background:

Coercion in mental healthcare has led to ethical debate on its nature and use. However, few studies have explicitly explored patients’ moral evaluations of coercion.

Aim:

The purpose of this study is to increase understanding of patients’ moral views and considerations regarding coercion.

Research design:

Semi-structured focus-group and individual interviews were conducted and data were analysed through a thematic content analysis.

Participants and research context:

A total of 24 adult participants with various mental health problems and experiences with coercion were interviewed in 2012–2013 in three regions of Norway.

Ethical considerations:

Ethical approval and permissions were obtained according to required procedures. Informed consent and confidentiality were also secured.

Findings:

Ethical considerations regarding coercion included seven main themes: the need for alternative perspectives and solutions, the existence of a danger or harm to oneself or others, the problem of paternalism, the problem of discrimination and stigma, the need for proportionality, the importance of the content and consequences of coercion and concerns about way that coercion is carried out in practice.

Discussion:

The participants’ views and considerations are in line with previous research and reflect the range of normative arguments commonly encountered in ethical and legal debates. The study accentuates the significance of institutional factors and alternative voluntary treatment opportunities, as well as the legal and ethical principles of proportionality and purposefulness, in moral evaluations of coercion.

Conclusion:

Broader perspectives on coercion are required to comprehend its ethical challenges and derive possible solutions to these from a patient perspective.
National Trends in Home Treatment of Acute Pulmonary Embolism
Authors: Stein Paul D. , Matta Fadi , Hughes Mary J.
Published: October 2016

Background:

Management of patients with acute pulmonary embolism has evolved from obligatory hospitalization to home treatment of carefully selected low-risk patients. The purpose of this investigation is to determine national trends in the prevalence of home treatment of pulmonary embolism.

Methods:

The Nationwide Emergency Department Sample was used to determine the number of patients seen in emergency departments throughout the United States with a primary (first-listed) diagnosis of pulmonary embolism and the proportion hospitalized according to age, from 2007 to 2012. The National (Nationwide) Inpatient Sample was used to determine in-hospital all-cause mortality and length of stay of hospitalized patients. Patients were adults (≥18 years) of both genders and all races from all regions of the United States. Excluded patients were those in shock or on ventilator support. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify patients and comorbid conditions.

Results:

Home treatment was selected for 54 494 (6.0%) of 915 702 stable patients with acute pulmonary embolism. The proportion of patients treated at home was age-dependent, highest in those aged 30 years or younger, 12.1%, and lowest in those >80 years, 2.9%. Most patients treated at home, 66.8%, and had no comorbid conditions. In-hospital all-cause deaths were 2.6%. Deaths were ≤0.9% in those ≤40 years and 4.8% in those >80 years. Length of stay was 6 days or longer in 37.6% of patients.

Conclusion:

In view of the lower death rate among younger patients, they might be a group in whom home treatment would be more advantageous than in elderly patients.
Reversal of Anticoagulation and Management of Bleeding in Patients on Anticoagulants
Authors: Dhakal Prajwal , Rayamajhi Supratik , Verma Vivek , Gundabolu Krishna , Bhatt Vijaya R.
Published: October 2016

Bleeding is the most common complication of all anticoagulants. Any bleeding patient on an anticoagulant should be risk-stratified based on hemodynamic instability, source of bleeding, and degree of blood loss. Although minor bleed may be managed with discontinuation of anticoagulant, major bleed may require transfusion of blood products and use of specific antidote. The residual effects of each anticoagulant may be monitored with distinct coagulation assay. Intravenous or oral vitamin K can reverse the effect of warfarin within 24 to 48 hours and is indicated for any bleeding, international normalized ratio of >10 or 4.5 to 10 in patients with other risk factors for bleeding. Fresh frozen plasma or prothrombin complex concentrate (PCC) may be necessary in major bleeding related to warfarin. Protamine sulfate reverses the effect of unfractionated heparin completely and of low-molecular-weight heparin (LMWH) partially. Idarucizumab has recently been approved in United States for dabigatran reversal, whereas andexanet alfa is expected to get approved in the near future for reversal of oral factor Xa inhibitors. The PCC may reverse the effect of rivaroxaban to some extent, but no data are available regarding reversal of apixaban and edoxaban. Aripazine has shown promising results to reverse the effects of LMWH, fondaparinux, and direct oral anticoagulants but is still in the developmental phase.
The Effect of Social Networking Sites’ Activities on Customers’ Well-Being
Authors: Lee Seonjeong (Ally)
Published: October 2016

With the growing number of customers engaged with social networking sites (SNSs), scholars have started investigating the effects of SNSs’ activities on customers’ well-being perceptions. However, the extant literature has not fully investigated SNSs’ activities that influenced customers’ well-being perceptions when customers shared their hotel experiences. This study explored the effectiveness of the well-being marketing to investigate SNSs’ activities that influenced customers’ psychological needs and impact of a sense of well-being on customers’ brand usage intent, based on self-determination theory in the context of the hotel industry. Results from this study provided theoretical and practical implications on the roles of SNS activities that led to customers’ well-being perceptions.
Dramatising austerity: holding a story together (and why it falls apart . . .)
Authors: Raynor Ruth
Published: October 2016

A group of women in the North East of England; women getting on and getting by amidst austerity. But what does austerity become for these women? How does it surface and register in their everyday lives through a series of fragmented encounters? Together, we developed a fictional play to explore how austerity acted in the midst of other things. Effects ranged from the un-dramatic to the intense – from an empty flowerbed at the end of the street to service closure and a loss of support. How then to ‘evoke’ austerity in this article and through the narrative form of a play? Does austerity become atmospheric like smog – something cold and wet settled over the place? Like a coercive character making demands she cannot meet? Or a particular pattern of relations between event and effect: a plot that falls apart? Our attempts at dramatisation revealed austerity’s fracturing and dissonance. Austerity sapped women’s energy to flourish through existing attachments to one another, to family life and to other forms of unpaid care; it made promises it couldn’t keep; it disorientated. As austerity differently met and co-constituted the lives of women, it disrupted opportunity for collective experience so that even austerity was not commonly encountered. In that context, I work through the play and the process in its development to explore what we held together and what continued to fall apart. Story then works hard in this article. It becomes a promise of momentum towards resolution, an affective mechanism that organises lives in the chaos after financial crisis, a longed-for form for a coproduced play and a theory that might make some sense of why anti-austerity imaginaries were not coherently attached to at least by women in this process.
Reviewing the Focus: A Summary and Critique of Child-Focused Sexual Abuse Prevention
Authors: Rudolph Julia , Zimmer-Gembeck Melanie J.
Published: October 2016

Due to the high incidence, and widespread detrimental health consequences, of child sexual abuse (CSA), effective prevention remains at the forefront of public and mental health research, prevention and intervention agendas. To date much of the focus of prevention has been on school-based education programs designed to teach children skills to evade adult sexual advances, and disclose past or ongoing abuse. Evaluation of sexual abuse prevention programs demonstrate their effectiveness in increasing children’s knowledge of CSA concepts and protection skills, but little is known about their effects on children’s capacity to prevent abuse. Moreover, concerns persist about the unintended side-effects for young children such as anxiety, worry and wariness of touch. This paper summarizes the recent history of CSA prevention and the critique of child-focused protection programs in order to demonstrate the need to compliment or replace these programs by focusing more on protectors in the children’s ecology, specifically parents, in order to create safer environments in which abuse is less likely to occur.
Motor Learning in Stroke

Published: October 2016

Background and Objective: Stroke rehabilitation assumes motor learning contributes to motor recovery, yet motor learning in stroke has received little systematic investigation. Here we aimed to illustrate that despite matching levels of performance on a task, a trained patient should not be considered equal to an untrained patient with less impairment. Methods: We examined motor learning in healthy control participants and groups of stroke survivors with mild-to-moderate or moderate-to-severe motor impairment. Participants performed a series of isometric contractions of the elbow flexors to navigate an on-screen cursor to different targets, and trained to perform this task over a 4-day period. The speed-accuracy trade-off function (SAF) was assessed for each group, controlling for differences in self-selected movement speeds between individuals. Results: The initial SAF for each group was proportional to their impairment. All groups were able to improve their performance through skill acquisition. Interestingly, training led the moderate-to-severe group to match the untrained (baseline) performance of the mild-to-moderate group, while the trained mild-to-moderate group matched the untrained (baseline) performance of the controls. Critically, this did not make the two groups equivalent; they differed in their capacity to improve beyond this matched performance level. Specifically, the trained groups had reached a plateau, while the untrained groups had not. Conclusions: Despite matching levels of performance on a task, a trained patient is not equal to an untrained patient with less impairment. This has important implications for decisions both on the focus of rehabilitation efforts for chronic stroke, as well as for returning to work and other activities.
Scalp congenital hemangioma with associated high-output cardiac failure in a premature infant: Case report and review of literature
Authors: Shah Sumedh S , Snelling Brian M , Sur Samir , Ramnath Alexandra R , Bandstra Emmalee S , Yavagal Dileep R
Published: October 2016

Introduction

Scalp congenital hemangiomas (CHs) are rare vascular malformations among infants; they can be associated with an array of complications, including cardiac and cosmetic issues. Here, we report the endovascular treatment of a premature infant with a suspected large right parietal scalp hemangioma and associated high-output cardiac failure.

Case description

A two-day-old female premature infant (29 weeks gestational age; 1330 g birth weight) was referred by the neonatologists to our department for consultation and potential treatment of a large right parietal CH causing abrupt hypotension and high-output cardiac failure. Doppler ultrasound imaging at bedside revealed areas of arterial-venous shunting from the scalp and the presence of a superior sagittal sinus waveform, consistent with intracranial venous drainage. To alleviate cardiac dysfunction secondary to this lesion, trans-arterial embolization via n-butyl cyanoacrylate (nBCA) glue and deployment of detachable coils was performed via umbilical artery to occlude the right superficial temporal and occipital artery branches supplying the CH. Following treatment, the infant continued to require ventilator management, vasopressor support, and correction of coagulopathy, but by post-operative day two, her condition improved remarkably and the mass size began decreasing. The patient was discharged after a relatively uncomplicated subsequent 2½-month course in the neonatal intensive care unit.

Conclusion

Endovascular therapy proved effective and safe in treating cardiac failure associated with scalp CH, despite potential complications associated with neuro-interventional surgery in premature infants. Appropriate consideration in this patient population should be given to factors including blood loss, contrast use, radiation exposure, operative time, and possible intra-/post-operative complications.
Prevalence of decompression surgery in patients with carpal tunnel syndrome 8 years after initial treatment with a local corticosteroid injection
Authors: Hameso A. , Bland J. D. P.
Published: October 2016

Repeated local corticosteroid injections have become a common mode of treatment for carpal tunnel syndrome, despite an existing recommendation that no more than three injections should be given. We studied the clinical outcomes in 254 patients who initially opted for a corticosteroid injection into their carpal canal during 2007. Follow-up records of treatment were obtained for 157 patients of whom 41% had proceeded to surgery by 2015. A mean of 1.9 injections had been given before surgery. In the unoperated group, a mean of two (range 0–12) further injections had been given. The final subjective severity and functional status scores measured using the Boston carpal tunnel questionnaire were significantly lower in the operated than in the unoperated group, but both groups improved significantly from baseline. The differences between the final scores are less than the estimated minimal clinically important difference for these measures. We conclude that repeated steroid injection may be a valid treatment option for some patients with carpal tunnel syndrome.

Lactate is considered an important metabolite in the human body, but there has been considerable debate about its roles in brain function. Research in recent years has suggested that lactate from astrocytes may be crucial for supporting axonal function, especially during times of high metabolic demands or hypoglycemia. The astrocyte-neuron lactate transfer shuttle system serves a protective function to ensure a supply of substrates for brain metabolism, and oligodendrocytes appear to also influence availability of lactate. There is increasing evidence for lactate acting as a signaling molecule in the brain to link metabolism, substrate availability, blood flow and neuronal activity. This review will attempt to connect evidence to the relationship lactate has to panic disorder (PD), which suggests that its transporters, receptors or metabolism warrant investigation as potential therapeutic targets in PD.
Liberal democracy as the end of history
Authors: Shin Doh Chull , Kim Hannah June
Published: October 2016

A growing number of political scientists have recently advocated the theses that democracy has emerged as a universal value and that it is also becoming the universally preferred system of government. Do most people in East Asia prefer democracy to nondemocratic systems, as advocates of these Western theses claim? Do they embrace liberal democracy as the most preferred system as they become socioeconomically modernized and culturally liberalized? To address these questions, we first propose a typology of privately concealed political system preferences as a new conceptual tool in order to ascertain their types and subtypes without using the word “democracy”. By means of this typology, we analyze the third wave of the Asian Barometer Survey conducted in 12 democratic and nondemocratic countries. The analysis reveals that a hybrid system, not liberal democracy, is the most preferred system even among the culturally liberalized and socioeconomically modernized segments of the East Asian population. Our results show that the increasingly popular theses of universal and liberal democratization serve merely in East Asia as prodemocracy rhetoric, not as theoretically meaningful propositions.
No Association Between Return to Play After Injury and Increased Rate of Anterior Cruciate Ligament Injury in Men’s Professional Soccer
Authors: Lundblad Matilda , Waldén Markus , Hägglund Martin , Ekstrand Jan , Thomeé Christoffer , Karlsson Jón
Published: October 2016

Background:

Studies have shown that previous injury, not necessarily anatomically related, is an important injury risk factor. However, it is not known whether a player runs an increased risk of anterior cruciate ligament (ACL) injury after returning to play from other injury types.

Purpose:

To analyze whether professional soccer players are more susceptible to ACL injury after returning to play from any previous injury.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

A total of 101 elite male soccer players suffering a first-time complete ACL injury between 2001 and 2014 were included and matched according to team, age, and playing position with control players who did not have a current injury (1:1 match). For each injured player, the 90-day period prior to the ACL injury was analyzed for injuries and compared with that of control players by using odds ratios (ORs) and 95% CIs.

Results:

The odds of a player with an ACL injury sustaining a previous injury in the 90-day period did not differ significantly from that of controls (OR, 1.20; 95% CI, 0.66-2.17; P = .65). Testing the frequency of absence periods due to injury between the groups revealed that the odds of a player with an ACL injury having a previous period of absence due to injury did not differ compared with controls (OR, 1.14; 95% CI, 0.64-2.01; P = .77).

Conclusion:

Players with ACL injury did not have a greater occurrence of absence due to injury in the 3 months preceding their ACL injury compared with matched controls. This indicates that previous injury of any type does not increase the risk of suffering an ACL injury.
Seizures Related to Hypomagnesemia
Authors: Chen Becky Biqi , Prasad Chitra , Kobrzynski Marta , Campbell Craig , Filler Guido
Published: October 2016

Objective:

Childhood seizures have various nonneurological etiologies. The patient’s magnesium levels should be measured when evaluating afebrile seizures. The purpose of the current case series is to describe a systematic approach for diagnosing hypomagnesemia using 3 recent patient cases.

Methods:

This case series describes 3 patients with unprovoked hypomagnesemia-associated seizures. The authors describe the differential diagnosis, pathophysiology, and the workup of hypomagnesemia-associated seizures.

Results:

Hypomagnesemia contributed to the cause of the seizures in all 3 cases. Various causes of hypomagnesemia were investigated, including genetic etiologies. All 3 patients were maintained at a magnesium level >0.65 mmol/L, which improved or eliminated the seizures.

Significance:

Magnesium levels should always be measured when trying to determine the etiology of seizures. Hypomagnesemia and afebrile seizures should be treated with the goal of maintaining a magnesium concentration >0.65 mmol/L. Although rare, genetic causes of hypomagnesemia should be considered, once common causes of hypomagnesemia are ruled out.
An analysis of simple computational strategies to facilitate the design of functional molecular information processors
Authors: Lee Yiling , Roslan Rozieffa , Azizan Shariza , Firdaus-Raih Mohd , Ramlan Effirul I.
Published: October 2016

Background

Biological macromolecules (DNA, RNA and proteins) are capable of processing physical or chemical inputs to generate outputs that parallel conventional Boolean logical operators. However, the design of functional modules that will enable these macromolecules to operate as synthetic molecular computing devices is challenging.

Results

Using three simple heuristics, we designed RNA sensors that can mimic the function of a seven-segment display (SSD). Ten independent and orthogonal sensors representing the numerals 0 to 9 are designed and constructed. Each sensor has its own unique oligonucleotide binding site region that is activated uniquely by a specific input. Each operator was subjected to a stringent in silico filtering. Random sensors were selected and functionally validated via ribozyme self cleavage assays that were visualized via electrophoresis.

Conclusions

By utilising simple permutation and randomisation in the sequence design phase, we have developed functional RNA sensors thus demonstrating that even the simplest of computational methods can greatly aid the design phase for constructing functional molecular devices.
Specific disruption of Lnk in murine endothelial progenitor cells promotes dermal wound healing via enhanced vasculogenesis, activation of myofibroblasts, and suppression of inflammatory cell recruitment

Published: October 2016

Background

Although endothelial progenitor cells (EPCs) contribute to wound repair by promoting neovascularization, the mechanism of EPC-mediated wound healing remains poorly understood due to the lack of pivotal molecular targets of dermal wound repair.

Methods and Results

We found that genetic targeting of theLnkgene in EPCs dramatically enhances the vasculogenic potential including cell proliferation, migration, and tubule-like formation as well as accelerates in vivo wound healing, with a reduction in fibrotic tissue and improved neovascularization via significant suppression of inflammatory cell recruitment. When injected into wound sites,Lnk-/-EPCs gave rise to a significant number of new vessels, with remarkably increased survival of transplanted cells and decreased recruitment of cytotoxic T cells, macrophages, and neutrophils, but caused activation of fibroblasts in the wound-remodeling phase. Notably, in a mouse model of type I diabetes, transplantedLnk-/-EPCs induced significantly better wound healing thanLnk+/+EPCs did.

Conclusions

The specific targeting of Lnk may be a promising EPC-based therapeutic strategy for dermal wound healing via improvement of neovascularization but inhibition of excessive inflammation as well as activation of myofibroblasts during dermal tissue remodeling.
On-site monitoring for better selection of stone repairs: a case study

Published: October 2016

Weathering of clay-bearing sandstones does not only depend on material properties but also on the environmental conditions they are exposed to. The same is true for repaired stones, in which the compatibility of the repair mortar should be studied not only in terms of material properties, but also in terms of the climatic conditions it will be subjected, in order to maximize this compatibility. This paper proposes a methodology to quantify the thermal and hygric stresses in clay-bearing sandstones and their repair, based on the measurement of temperature and relative humidity at the surface and at several depths in a repaired and a non-repaired stone, as well as wind-driven rain and absorbed water. This is illustrated by a case study in an historical building. The data are used to quantify the stresses in the materials and to propose possible degradation mechanisms.
