Quantitative Skills, Critical Thinking, and Writing Mechanics in Blended Versus Face-to-Face Versions of a Research Methods and Statistics Course
Authors: Goode Christopher T. , Lamoreaux Marika , Atchison Kristin J. , Jeffress Elizabeth C. , Lynch Heather L. , Sheehan Elizabeth
Published: March 2018

Hybrid or blended learning (BL) has been shown to be equivalent to or better than face-to-face (FTF) instruction in a broad variety of contexts. We randomly assigned students to either 50/50 BL or 100% FTF versions of a research methods and statistics in psychology course. Students who took the BL version of the course scored significantly lower on measures of quantitative mastery of statistical concepts than those who took the FTF version; however, the size of this effect was quite small. We detected no significant difference between BL and FTF in the expression of critical thinking through writing or writing mechanics. The greatest difference in performance was among instructors regardless of instruction type. We discuss these results in the context of increasing online and BL instruction, particularly with regard to teaching psychological statistics, research methods, and critical thinking.
Dusting Off the Knowledge Shelves: Recombinant Lag and the Technological Value of Inventions
Authors: Kok Holmer , Faems Dries , de Faria Pedro
Published: March 2018

Whereas knowledge recombination research tends to focus on original knowledge component attributes and their recombinant value implications, we contribute to an emerging literature stream on knowledge reuse trajectories, investigating the temporal dimension of reuse by introducing the concept of recombinant lag, that is, the time that components have remained unused. Relying on organizational learning theory, we emphasize that it is important to consider not only the frequency of reuse but also the recency of reuse. Our core argument is that recent reuse of knowledge components can trigger a rejuvenation effect that influences the value of resulting inventions. Analyzing 21,117 fuel cell patent families, we find an unexpected U-shaped relationship between recombinant lag and the value of inventions, which is moderated by frequency of reuse. Conducting post hoc exploratory data analyses, we advance the concept of dormant components (i.e., valuable components that have remained unused prolongedly) as a potential explanation for this unexpected U-shaped pattern. Moreover, collecting and analyzing data on a second sample in the wind energy industry, we provide first indications for the generalizability of these unexpected findings. We contribute to a richer understanding of reuse trajectories, highlighting that next to the magnitude of reuse information flows, that is, information flows that are generated when components are reused, the timing of creation of these information flows shapes the value of subsequent recombination activities. We also contribute to extant research on the temporal dimension of knowledge recombination, pointing to recombinant lag as an important aspect next to component age.

Predicting women’s emotional responses to hooking up
Authors: de Jong David C. , Adams Katie N. , Reis Harry T.
Published: March 2018

Among young women, hookups have been found to lead to varied emotional responses. The authors tested three hypotheses to disentangle these contradictory findings in a weekly diary study. A trait-level motives hypothesis suggests that trait-level motives moderate emotional responses to hookups. A motive satisfaction hypothesis suggests that emotional responses to hooking up depend on satisfaction within hookups. A dual-effects hypothesis proposes the co-occurrence of positive and negative emotional responses. In this study, 203 college women reported trait-level motives for hooking up (e.g., pleasure/fun, intimacy, coping). Next, 5 weekly surveys asked about recent hookup experiences. These responses were compared to the same women’s emotions on weeks they did not hook up, thereby controlling for selection bias. All three hypotheses were supported. Pleasure/fun motives predicted more positive and less negative emotions; satisfaction of pleasure, intimacy, and affirmation motives resulted in more positive and less negative emotions; and simultaneous positive and negative reactions were common.
Pornography’s associations with open sexual communication and relationship closeness vary as a function of dyadic patterns of pornography use within heterosexual relationships
Authors: Kohut Taylor , Balzarini Rhonda N. , Fisher William A. , Campbell Lorne
Published: March 2018

Couples who use pornography together (shared pornography use) and couples in which both members use pornography alone (concordant solitary pornography use) may have more sexual interests, preferences, and values in common than couples in which one couple member uses pornography and the other does not (discordant pornography use). From this perspective, the associations between pornography use, comfort in sexual communication, and relationship closeness should vary depending on patterns of pornography use within relationships. Several related pre-registered hypotheses were tested using an online cross-sectional survey of heterosexual dyads ( N = 200) that were quota sampled to reflect the distribution of age and political affiliation of married American couples. Dyadic analysis indicated that participants who shared pornography use with their partner reported more open sexual communication and greater closeness than those that did not. Further, participants who were in relationships that were discordant in solitary pornography use reported more inhibited sexual communication and lower closeness than participants who were in relationships that were concordant in solitary pornography use. In fact, couples who were concordant in high-frequency solitary pornography use reported similar openness in sexual communication and closeness as couples in which neither partner used pornography alone. These findings have important implications for the field, because they reinforce the view that the links between pornography use and relationship health are largely a function of different patterns of pornography use within couples.
Breadth of Emotion Vocabulary in Early Adolescence
Authors: Bazhydai Marina , Ivcevic Zorana , Brackett Marc A. , Widen Sherri C.
Published: March 2018

Studies of emotion vocabulary and understanding typically focus on early childhood. Yet, emotion abilities continue to develop into adolescence, making it an important and underinvestigated area of research. This study presents evidence that adolescents’ emotion vocabulary undergoes active development, becomes more broad and sophisticated, varies by gender, and is not captured adequately by recognition-based approaches. Adolescents were asked to generate emotion words for five emotion categories— happy, relaxed, angry, sad, and nervous. Responses included emotion words (e.g., joyous) and nonemotion terms such as metaphors (e.g., boiling), social experiences (e.g., underappreciated), and personality traits (e.g., shy). Girls generated significantly more responses than boys. Older adolescents generated significantly more emotion words (e.g., describing someone who is happy as joyful, exuberant or ecstatic), while younger adolescents produced more nonemotion responses (e.g., describing someone who is happy as smiley, friendly, or full of life). Students’ grade, total number of responses they produced, and performance on the recognition test of emotion understanding predicted their emotion vocabulary.
Chemical warfare in Colombia, evidentiary ecologies and senti-actuando practices of justice
Authors: Lyons Kristina
Published: March 2018

Between 1994 and 2015, militarized aerial fumigation was a central component of US-Colombia antidrug policy. Crop duster planes sprayed a concentrated formula of Monsanto’s herbicide, glyphosate, over illicit crops, and also forests, soils, pastures, livestock, watersheds, subsistence food and human bodies. Given that a national peace agreement was signed in 2016 between FARC-EP guerrillas and the state to end Colombia’s over five decades of war, certain government officials are quick to proclaim aerial fumigation of glyphosate an issue of the past. Rural communities, however, file quejas (complaints or grievances) seeking compensation from the state for the ongoing effects of the destruction of their licit agro-forestry. At the interfaces of feminist science and technology studies and anthropology, this article examines how evidentiary claims are mobilized when war deeply politicizes and moralizes technoscientific knowledge production. By ethnographically tracking the grievances filed by small farmers, I reveal the extent to which evidence circulating in zones of war – tree seedlings, subsistence crops, GPS coordinates and bureaucratic documents – retains (or not) the imprints of violence and toxicity. Given the systematic rejection of compensation claims, farmers engage in everyday material practices that attempt to transform chemically degraded ecologies. These everyday actualizations of justice exist both alongside and outside contestation over the geopolitically backed violence of state law. Rather than simply contrasting everyday acts of justice with denunciatory claims made against the state, farmers’ reparative practices produce an evidentiary ecology that holds the state accountable while also ‘ senti-actuando’ (feel-acting) alternative forms of justice.
Meeting my child for the first time: adoptive parents’ experiences of the period of adoption transition
Authors: Lewis Lisa
Published: March 2018

This article presents findings from a small-scale qualitative research study exploring the experiences of adoptive parents during adoption transitions – the time between when a match with a child is made until a number of months after placement. What happens during this period can have a bearing on the future success of the placement and long-term well-being of the child. The article seeks to explore the experiences of adoptive parents during this stage of the process in order for practitioners to become better informed about what can make transitions successful.

Semi-structured interviews were conducted with nine parents to capture the narrative of their adoption transition experience. Thematic analysis of the conversations revealed five main themes: rigidity, scrutiny, support, overall reflections and the relationship with the foster carer. The findings suggest that the transition period was a significant but problematic stage in the adopters’ overall adoption journey. Considerable inconsistency in the approach taken to practice in this area affected their experiences. The research highlighted areas of practice which are out of sync with that recommended in the literature; the article concludes with recommendations for promoting consistency.
Psychological interventions for adoptive parents: a systematic review
Authors: Harris-Waller Jayne , Granger Charlotte , Hussain Misbah
Published: March 2018

A systematic review methodology was used to evaluate research regarding psychological interventions for adoptive parents. The effectiveness of the diverse intervention models scrutinised was found to be mixed with regard to a range of parent and child outcomes. When service user feedback was sought, psychological interventions were found to be acceptable to adoptive parents. Overall, findings were weakened by multiple sources of potential bias in the studies reviewed. Further research is needed, with particular attention to the method, site and timing of outcome measurement, before firm clinical recommendations can be made regarding the relative benefit of specific models of psychological intervention for adoptive parents. Implications for future research are discussed with reference to the unique contextual challenges of conducting clinical studies with adoptive families.
Predictors of Clinical Outcomes After Hip Arthroscopy: A Prospective Analysis of 1038 Patients With 2-Year Follow-up
Authors: Domb Benjamin G. , Martin Timothy J. , Gui Chengcheng , Chandrasekaran Sivashankar , Suarez-Ahedo Carlos , Lodhia Parth
Published: March 2018

Background:

As hip arthroscopy has expanded in popularity and volume, more information is needed about indications for the procedure and the predictive factors of clinical outcomes.

Purpose:

To evaluate clinical outcomes of hip arthroscopy in a prospective study and to analyze the cohort to identify factors that are predictive of improvement.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

Data were collected prospectively on all patients undergoing hip arthroscopy between February 2008 and June 2012. We included all patients undergoing hip arthroscopy who agreed to participate and who completed 4 patient-reported outcome (PRO) instruments at a minimum 2-year follow-up: the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score–Activities of Daily Living (HOS-ADL), and Hip Outcome Score–Sport-Specific Subscale. The NAHS was selected as our primary outcome instrument. All patients with any previous hip conditions were excluded. We analyzed 34 preoperative and intraoperative variables using bivariate and multivariate analyses compared with NAHS.

Results:

The cohort consisted of 1038 patients with a mean follow-up of 30.1 months (range, 24.0-61.2 months). Mean age was 36.4 years (range, 13.2-76.4 years). All postoperative PRO scores showed significant improvement ( P < .001) at 2 years compared with preoperative scores. Bivariate analysis identified 15 variables (7 categorical and 8 continuous) and multivariate analysis identified 10 variables that were predictive of 2-year postoperative NAHS. Preoperative NAHS, preoperative HOS-ADL, preoperative mHHS, age, duration of symptoms, body mass index (BMI), and revision hip arthroscopy were identified as predictive factors in both bivariate and multivariate analyses. The predictive value of preoperative NAHS was accentuated for patients with higher BMI.

Conclusion:

This study reports favorable clinical outcomes in the largest cohort of hip arthroscopies with a minimum 2-year follow-up in the literature to date. Factors identified as predictive in both bivariate and multivariate analyses included preoperative NAHS, HOS-ADL, and mHHS; age; duration of symptoms; BMI; and revision hip arthroscopy. These predictive factors may be useful to the clinician in determining prognosis and operative indications for hip arthroscopy.
Enhanced lightweight design by composites – Results of the EU project ENLIGHT
Authors: Mayer Dirk , Bein Thilo , Buff Hendrik , Götz Benedict , Schwarzhaupt Oliver , Spancken Dominik
Published: March 2018

Over recent decades, cars have become larger and heavier with every new generation. The main drivers of such a weight increase have been the improved safety and comfort requirements. Decades of R&D investments to tackle this tendency have resulted in a substantial increase in the weight-specific performance of components and assemblies in terms of cost, strength and stiffness. However, the need for weight reduction in future electric vehicles, without unduly compromising performance and safety, is even stronger since additional weight translates into either reduced driving range or in larger, heavier and more expensive batteries. Within this context, the European Green Vehicle project ENLIGHT developed highly innovative lightweight material technologies for application in structural vehicle parts of future volume produced electric vehicles. Among others, ENLIGHT developed thermoplastic matrix composite and associated manufacturing technologies to a stage that they were applicable at least in medium volume production. The material development was complemented by investigating the required manufacturing and assembly technologies as well. In this paper, a summary of the major results obtained during the four-year project year is presented. A special focus is given to a semi-active composite control arm with significant reduced weight but enhanced NVH properties.
Toward Understanding Through Hermeneutic Letterwriting
Authors: Nyholm Linda , Nyström Lisbet , Lindström Unni Å.
Published: March 2018

The authors present letterwriting as a hermeneutic research method in that it contributes to the methodological development within the hermeneutical research tradition in caring science. The hermeneutic methodology is inspired by Hans-Georg Gadamer. Hermeneutic letterwriting in accordance with Gadamer’s thought is a form of dialogue in writing, where what is truthful about the thing itself is unveiled with the help of the language. Hermeneutic letterwriting is presented in five steps. As a method, hermeneutic letterwriting is appropriate for complex caring science issues, and it offers new opportunities for attaining a deeper understanding of the world of caring.

Efficacy and Safety of Basal Insulin/GLP-1 Receptor Agonist Used in Combination for Type 2 Diabetes Management
Authors: McCarty Delilah , Olenik Alaina , McCarty Bryan P.
Published: March 2018

Purpose:

The purpose of this article is to review the efficacy, safety, and place in therapy of insulin degludec/liraglutide (IDegLira) and insulin glargine/lixisenatide (IGlarLixi) in the treatment of type 2 diabetes mellitus.

Type 2 diabetes is a condition affecting nearly 30 million American adults. Management of type 2 diabetes is complex and multifactorial. Using medications targeted at a variety of the physiologic defects known to contribute to the development of type 2 diabetes allows for a patient-specific approach to care. Utilizing combination products is a way to target several areas of the disease while decreasing the complexity and burden to the patient. Basal insulin/glucagon-like peptide-1 (GLP-1) agonist combination products have the benefit of being highly efficacious while having favorable effects on weight, reduced gastrointestinal adverse effects, and low hypoglycemic risks compared to the individual agents used alone.

Conclusion:

This article will review 2 basal insulin/GLP-1 agonist combination products, IDegLira and IGlarLixi, which were approved in November 2016.

Published: March 2018

The purpose of this investigation is to apply imposing node technique for vibration reduction of petrol engine grass trimmer handle using vibration absorber. The algorithm is devised to find the required resonance frequency of the absorber to impose node at desired location on beam. The numerical simulations are performed to find the usefulness of absorber for imposing nodes at the handle attachment location on timer pipe. The experimental test is conducted to validate the numerical results and to evaluate the vibration suppression during no cutting and cutting conditions. The vibration total value measured at handle of grass trimmer shows that absorber is useful in handle vibration reduction.
Cause factors in emergency process of fire accident for oil–gas storage and transportation based on fault tree analysis and modified Bayesian network model
Authors: Yuan Changfeng , Cui Hui , Tao Bin , Ma Siming
Published: March 2018

From the perspective of the safety of emergency process, in this paper, we put forward a new analysis method of cause factors based on fault tree analysis and modified Bayesian network in emergency process of fire accident for oil–gas storage and transportation. Nineteen cause factors are found based on the statistical analysis of actual accident cases. We adopt fault tree analysis method and Bayesian network model to analyze cause factors qualitatively and quantitatively. In order to more accurately determine the quantitative influencing degree of each cause factor, the conditional probabilities in Bayesian network are modified by using expert scoring method and modified Bayesian network model is established. Finally, the proposed method is applied to analyze cause factors in emergency process of two practical accident cases. Research results have an important scientific significance to reveal evolution mechanism of secondary accidents in emergency process and ensure system safety in whole life cycle.
#CleftProud
Authors: Stock Nicola Marie , Martindale Anna , Cunniffe Claire
Published: March 2018

Background:

More than 2 billion people worldwide now use social networking sites, with an increasing number of users accessing these sites to obtain health information and engage in emotional support. Yet, investigation of social networking sites in the context of cleft lip and/or palate (CL/P) has been scarce.

Methods:

Real-time data posted during 2 weeks in April 2017 were collected from 2 existing private Facebook groups (hosted by the Cleft Lip and Palate Association United Kingdom) using video screen capture software. The number of posts, comments, unique contributors, and post “likes” was recorded, as well as the type and theme of each post. Data relating to the benefits and challenges of participation in the 2 groups were also collected via an online survey.

Results:

A content analysis of real-time data identified perioperative care, associated syndromes, and dental health to be particular areas of concern for parents/caregivers. Expectations, experiences, and outcomes of further treatment were key topics of discussion for adults with CL/P. Common benefits of the groups included the ability to connect with others, learn about local events, give and receive emotional support, and obtain quick responses to queries in a semi-anonymous environment. Disadvantages of the groups included a reliance upon opinion rather than medical fact and the frequent use of inappropriate terminology.

Conclusions:

Social networking sites appear to be a helpful source of health-related information and peer support for the CL/P population, yet closer monitoring of these groups may be required.

Authors: Kuebel Christa R. , Koops Lisa Huisman , Bond Vanessa L.
Published: March 2018

The purpose of this autonarrative inquiry was to explore the professional identity development and mentoring relationships of three general music teacher educators during their time at one university. We present our stories of development and re-visioning as general music methods educators through our roles as educator, learner, and co-learner while having taught or team-taught general music methods at Case Western Reserve University (Cleveland, Ohio) over the past 10 years. Data included individual journals and transcripts of monthly Google text chats and conference calls. We analyzed the data through the commonplaces of temporality, sociality, and place, and engaged in re-storying. Investigating the process of becoming a general music methods instructor provided important insights concerning the impact of time, people, and places on the transition from music teacher to music teacher educator.

Chronic Lower Back Pain
Authors: Wirick Dawn M. , Teufel-Prida Lee A.
Published: March 2018

Chronic lower back pain is a major health concern involving physical, financial, and social costs for many patients and their family members. Contemporary pain management is guided by the biopsychosocial model in which a professional counselor can contribute to recovery through integrated behavioral health care. Cognitive behavioral therapy (CBT) and behavioral activation interventions are effective in breaking the cycle of chronic pain. Successful outcomes involve partners and family members in CBT, education, and structural family interventions. A case study is presented to examine thoughts and feelings associated with chronic lower back pain. CBT and family interventions contribute to recovery of functions, meaningful roles, and health in relationships.
Disconnects and Silos in Transitional Care: Single-Case Study of Model Implementation in Home Health Care
Authors: Smith Audris D. , Treschuk Judith
Published: March 2018

Transitional care incorporates actions to ensure the coordination and continuity of care between provider settings (ie, hospitals, nursing homes, home health care, patients’ home, and physician offices) occurs to meet the patient’s goals relative to their disease management. The evolution of transitional care over the past decade has facilitated the emergence of several transitional care models. However, there is a dearth of understanding related to the collaboration between nurse transition coaches and home care nurses when implementing transitional care model activities to achieve desired patient outcomes in the home health care setting. This case study describes the enactment of a specific transitional care model’s conceptual framework to derive an in-depth understanding of the collaborations between nurse transition coaches and home health nurses in the unique context of home health care. The case is a specific patient-centered Care Transitions Intervention (CTI) model with 4 embedded subunits: (1) the experiences and actions of the nurse transitions coach, (2) the experiences and actions of the home health nurse, (3) document and artifacts review, and (4) the experiences and observations of key leadership stakeholders involved in transitional care activities in one home health care organization located in Michigan.
Evaluation of hyaloid–retinal relationship during triamcinolone-assisted vitrectomy for primary rhegmatogenous retinal detachment
Authors: Sundar Dheepak , Takkar Brijesh , Venkatesh Pradeep , Chawla Rohan , Temkar Shreyas , Azad Shorya Vardhan , Vohra Rajpal
Published: March 2018

Aims:

To determine hyaloid–retinal relationship in primary rhegmatogenous retinal detachment during vitreous surgery.

Methods:

This is a prospective, interventional study of patients (n = 72) undergoing triamcinolone-assisted 25G vitreous surgery for primary rhegmatogenous retinal detachment. Hyaloid–retinal relationship was noted intraoperatively to identify regions and patterns of firm attachment and was classified into subgroups. Analysis was done to determine association between hyaloid–retinal relationship patterns and preoperative findings: posterior vitreous detachment, proliferative vitreoretinopathy, type of retinal tear, the presence of peripheral degenerations, and postoperative outcomes.

Results:

Three patterns of hyaloid–retinal relationship were identified: type1 (complete absence of posterior vitreous detachment (21%)), type 2 (incomplete posterior vitreous detachment (47%)) and type 3 (complete posterior vitreous detachment (32%)). Posterior vitreous detachment in some form was present in 84% of the cases with retinal tears as the causative break but none of the cases with retinal holes (p < 0.001). None of the cases with vitreoretinal degeneration had complete posterior vitreous detachment (p = 0.001). 69% of proliferative vitreoretinopathy–C cases had type 1 hyaloid–retinal relationship as compared to 11% cases with no proliferative vitreoretinopathy (p < 0.001). Proliferative vitreoretinopathy-related anatomical failure was seen in 7.5%, and 80% of these eyes with recurrent RD had type 1 hyaloid–retinal relationship (p<0.001). Nearly half the patients diagnosed as complete posterior vitreous detachment preoperatively were found to have incomplete posterior vitreous detachment intraoperatively.

Conclusions:

Majority of the cases with rhegmatogenous retinal detachment have some form of strong vitreoretinal adhesion. Hyaloid–retinal relationship varies with types of retinal breaks, retinal degeneration, and proliferative vitreoretinopathy. Intraoperative hyaloid–retinal relationship is frequently different from that assessed before surgery and the proposed classification may improve surgical decision making and prognostication.
Hypnosis as adjunct therapy to conscious sedation for venous access device implantation in breast cancer: A pilot study
Authors: Sterkers Nicolas , Chabrol Jean L , De Troyer Jeremy , Bonijol Dany , Darmon Jean C , Donnez Olivier
Published: March 2018

Background:

Recent reviews support that hypnosis has great potential for reducing pain and anxiety during mini-invasive surgery. Here, we assessed the feasibility of hypnotic induction session as adjunct therapy in conscious sedation for venous access device implantation. Primary outcomes were safety and patient satisfaction.

Methods:

Thirty consecutive women with breast cancer were proposed adjunct of hypnosis before implantation under conscious sedation (midazolam: 0.5 mg ± bolus of Ketamin: 5 mg on demand) indicated for chemotherapy. Self-hypnosis was programmed and guided by one of two trained anesthesiologists. Implantation was performed by one of two experimented surgeons. It consisted of blind subclavian implantation of Braun ST 305 devices using a percutaneous technique adapted from Selinger’s procedure. Clinical data were prospectively collected and retrospectively analyzed. A comprehensive custom-made questionnaire recorded patient satisfaction.

Results:

In all, 30/30 patients consented to the procedure. The median age was 54 years (range: 35–77 years). The primary procedure was successful in 29/30. One case was converted into internal jugular vein access after a first attempt. Median length time of the implantation procedure in the operative room was 20 min (range: 10–60 min). Median length time in the recovery room preceding home discharge was 65 min (range: 15–185 min). None of the patients suffered complications. The satisfaction rate was ≥90%, 27/30 patients would get hypnosis in case of reimplantation if necessary and 27/30 would recommend this procedure to others.

Conclusion:

Hypnosis under conscious sedation appears feasible and safe for port implantation under conscious sedation in cancer patients. Further studies would determine the exact value of hypnosis effectiveness.
Comprehensive Evaluation of Commercial Bisulfite-Based DNA Methylation Kits and Development of an Alternative Protocol With Improved Conversion Performance
Authors: Tierling Sascha , Schmitt Beate , Walter Jörn
Published: March 2018

DNA methylation is the most studied epigenetic modification with a wide range of regulatory functions in mammalian genomes. It almost exclusively resides on CpG dinucleotides and, among others, plays important roles in early embryo development, onset, and maintenance of cancer. During the past 3 decades, many approaches have been developed to discriminate methylated from unmethylated DNA including antibody-based enrichment of methylated DNA, restriction enzyme-based, or hybridization-based methods. The conversion of unmethylated cytosines to uracils by sodium or ammonium bisulfite is regarded as golden standard as this approach requires no enzymatic reaction and provides deep and reliable insight in methylation patterns at single-base resolution. Nowadays, there are many commercial kits for bisulfite conversion available but they perform differently and also vary in protocols and chemicals used. Here, we provide the first comprehensive and comparative evaluation of bisulfite conversion kits observing major differences in conversion efficiency and DNA degradation which greatly affect the performance of downstream applications, ie, polymerase chain reactions (PCRs). Moreover, deep sequencing of amplicons containing oxidized derivates of 5ʹ-methylC shows that none of the tested kits efficiently converts 5ʹ-formylC without substantial conversion of 5ʹ-methylC or 5ʹ-hydroxymethylC. Consequently, we developed a robust and easy-to-use protocol that allows maximal discrimination between 5ʹ-formylC and 5ʹ-methylC/5ʹ-hydroxymethylC with low DNA degradation and high PCR efficiency on the bisulfite-treated DNA. We highly recommend to use our time- and cost-efficient protocol for any genome-wide or local high-resolution bisulfite sequencing application to minimize conversion-dependent error rates.
The Experience of Confident Music Improvising
Authors: Shevock Daniel J.
Published: March 2018

Improvisation plays a substantial role within the world’s musical cultures. The purpose of this research was to explore the essence of the experience of confident music improvising. In this phenomenological study, confidence was considered a psychological experience and the confidence of improvisers the phenomenon under examination. The researcher compiled experiences through stories describing the phenomenon by interviewing three confident improvisers: a bluegrass fiddler, a jazz bassist and a baroque violinist. Vignettes portrayed the lifeworlds of these instrumentalists. The stories told were reduced through imaginative variation to identify which themes were essential, that is, shared among the participants’ unique experiences. The essential themes revealed were: listening, criticism-free environment, sequential experiences, passion for a style, and openness to learning. Music educators could potentially use these themes to enrich their own improvisation pedagogy.
We made this bed … now look who’s lying in it
Authors: Spector Bert , Wilson Suze
Published: March 2018

In considering the ‘Populist Responses to Austerity and Cultural Change: Brexit, Trumpism and Beyond’, there is a temptation, even a degree of comfort, in depicting 2016 as a kind of deviant moment in which non-elite anger and anxiety fueled an outburst of anti-progressive energy and the electoral victory of demagogues. The proposition put forth in this essay is that leadership scholarship is itself culpable. Transformational leadership, the dominant theme of that discourse, relies on the individual leader as an exceptional individual capable, even obliged, to reshape the worldview of followers in order to align them with the leader’s approach. By favoring an appeal to emotions over a rational exchange of positions, by assuming the superiority of one set of values over any others, by denying the validity of differing and/or conflicting interests, and by asserting authority based on hierarchical position rather than informed choice and consent, transformational leadership veered closely to our understanding of demagogues. Unintended though it may be, the dominant discourse becomes engrained as a ‘regime of truth’ into a pervasive, highly problematic social norm. Leadership scholars must accept a degree of responsibility and reconsider romantic notions of leadership in order to advance alternatives, not only to Trump and his particular agenda but also to the problematic assumptions embedded in and wider effects entwined with leadership thought.
An embarrassment of riches: The seduction of postfeminism in the academy
Authors: Liu Helena
Published: March 2018

Given critiques of postfeminism as a neoliberal and patriarchal discourse that has taken considerable tolls on professional life, its popularity in organisational practice seems out of place. This article explores the processes of postfeminism through an autoethnographic inquiry of my experiences working as a research fellow at a leadership research centre in Australia. In theorising from my narrative accounts as an early career scholar, I offer a view into the entangled processes of postfeminist knowledge production and my own making as a postfeminist subject. In doing so, I attempt to illustrate the seductive appeal of postfeminism as an ostensibly empowering process that ultimately preserves White elite class patriarchal power.
Prevalence of salivary human herpesviruses in pediatric multiple sclerosis cases and controls
Authors: Leibovitch Emily C , Lin Cheng-Te Major , Billioux Bridgette J , Graves Jennifer , Waubant Emmanuelle , Jacobson Steven
Published: March 2018

Background:

Multiple sclerosis (MS) is a multifactorial disease of unknown origin. The current paradigm is that disease develops in genetically susceptible individuals, influenced by environmental factors. Epstein–Barr virus (EBV) and human herpesvirus 6 (HHV-6) have particularly strong associations with the disease. Both viruses are typically acquired during childhood, decades before MS presents. However, in patients with pediatric MS, the temporal window between viral acquisition and disease onset is shortened, which may provide insights into the association of herpesviruses with MS.

Objective:

To compare the frequency of EBV and HHV-6 in the saliva of a cohort of pediatric MS patients and age-matched controls.

Methods:

The study enrolled 32 pediatric MS patients and 42 controls and evaluated saliva for HHV-6 u57 and EBV lmp-1 amplification by droplet digital polymerase chain reaction (ddPCR).

Results:

Pediatric MS patients did not differ from controls in the frequency or magnitude of salivary viral shedding. During the assessment of EBV positivity, distinct profiles emerged that correlated with target amplicon mutations.

Conclusions:

None of these mutations were evident in EBV-positive samples from pediatric MS patients, whereas they were present in pediatric controls, in addition to MS and control adults, suggesting differential host-immune control of EBV in this pediatric MS cohort.
Demographics and clinical characteristics of episodic hypothermia in multiple sclerosis
Authors: Toledano Michel , Weinshenker Brian G , Kaufmann Timothy J , Parisi Joseph E , Paz Soldán M Mateo
Published: March 2018

Background:

Episodic hypothermia (EH) can occur in multiple sclerosis (MS). The putative mechanism is impairment of thermoregulation due to a presumed demyelinating hypothalamic lesion.

Objective:

To describe a cohort of patients with MS, who developed EH.

Methods:

Patients were identified through review of the Mayo Clinic electronic medical record (1996 to July 2015). Search terms were [multiple sclerosis] or [MS] within the diagnoses field and [hypothermia] within any field. We reviewed records for accuracy of diagnoses and abstracted relevant data. Magnetic resonance imaging (MRI) was reviewed for presence of hypothalamic lesions.

Results:

Of 156 patients, 34 had concurrent MS and hypothermia. Thirty-two (94%) had progressive disease at EH onset. Median MS duration was 19.9 years, and median expanded disability status scale (EDSS) was 8.0. Most patients presented with alterations in consciousness. Infection was suspected as the precipitating factor in 19 (56%), but clinically/laboratory supported in only 9 (28%). MRI lesions were evident within the hypothalamus in only 4 (14%).

Conclusion:

EH occurs predominantly in patients with advanced secondary progressive MS. The major manifestation is altered consciousness. Infection is often suspected as causal, but infrequently confirmed. Although commonly implicated, hypothalamic lesions were rarely evident on MRI and were absent in two post-mortem evaluations.
What does it mean to be rich? Some conceptual and empirical issues
Authors: Concialdi Pierre
Published: March 2018

Over the past decade, a growing literature has shed light on the rise of inequalities at the very top of the income distribution. There is no doubt that such extreme inequalities do threaten social cohesion and that some public policies are needed in order to tackle this issue. The design of these policies requires setting some benchmarks that could serve, at least, as guidelines to promote efforts towards the reduction of inequalities. In the same way that the fight against poverty can usefully benefit from researchers’ efforts to define poverty, the fight against extreme inequalities could also benefit from some definition of rich people. Nevertheless, very little attention has been given to the definition of the rich in the academic literature. The purpose of the paper is to try to fill this gap. It draws on previous definitions of an affluence line and proposes some estimates for three countries (France, Ireland and the UK).
Sustainable development and requirements for energy efficiency in buildings – The Korean perspectives
Authors: Kim Jeong Tai , Yu Chuck Wah Francis
Published: March 2018

The purpose of this paper is to provide a review of developments in Korea in relation to its energy consumption and sustainable development policies and progress in achieving its energy targets as given by the Building Energy Codes. Building insulation and passive building technologies are also reviewed for achieving passive house standards by 2017 and zero-energy or near zero-energy buildings (nZEB) by 2025 in Korea, and to identify strategies to further reduce usage of primary energy and to achieve energy efficiency targets. A defining feature of a sustainable building is its ability to reduce significantly its environmental impacts and its embodied energy and greenhouse gas emissions over its whole life, including use of natural resources and releases of pollutants, to promote reuse and recycling of materials and sustainable development of buildings whilst ensuring the building satisfy the indoor environmental quality requirements for occupants. Passive technologies include the use of natural ventilation, energy storage such as using phase change materials (PCM) and high thermal mass structure, high energy efficiency windows and lighting and maximizing daylighting and use of renewable energy technologies. Technologies for refurbishment of building envelopes, windows and ventilation systems are reviewed to improve and upgrade the energy efficiency of existing buildings as well as focusing on new builds. The various options for heating, ventilating, cooling and air-conditioning of buildings are also discussed. Green Buildings and Energy Efficiency Labels and Standards should have a pertinent role to affect energy efficiency measures in building developments.

Using an experiment and probability sample of Chicago and Los Angeles adults ( N = 1211), this study tested how tweet characteristics (tone, space) and participant age (younger, middle, older) affected attitudes about tweets from a local newspaper. Results indicate that non-opinionated tweets were perceived as more useful and credible than opinionated tweets, and local tweets resulted in more engagement than national tweets. Younger participants (19–36 years) reported more positive affect, usefulness, engagement, and credibility related to tweets than did middle/older age groups. Younger participants were generally more negative about opinionated national tweets and preferred opinionated local tweets compared with middle/older groups.
Advance care planning for people with dementia: Ordinary everyday conversations
Authors: de Vries Kay , Drury-Ruddlesden Jenny
Published: March 2018

Advance care planning for people with dementia has become a focus of dementia care policies in developed countries. In New Zealand, the framework for dementia care relies on the person with dementia having a level of competence to enable them to participate in the planning process. For people with dementia, it may be too late to initiate these discussions in terms of decision-making capacity. Consequently, decisions about end-of-life care for people with dementia are typically made by a family member who acts as a surrogate decision maker on behalf of the person with dementia. An exploratory qualitative study of 23 people who had been carers or provided support for a family member with dementia who had died within five years of the interview was undertaken. The overarching theme, ‘ordinary everyday conversations’, describes how informal conversations and discussions within the family relating to preferences at the end of life had been embedded in interactions within the families over years. Sub-themes revealed three important components enabling adherence to the prior wishes of the person with dementia through these conversations: knowing the person and belief in ‘doing the right thing’; the importance of Wills and Enduring Power of Attorney; and negotiating unexpected encounters. There is potential for families to be well prepared for the time when they may need to make decisions for the person with dementia based on ordinary everyday conversation that take place within families and throughout life. This study also suggests that more innovative approaches to making a Will may provide an important vehicle for expressing advanced care wishes.
Museum lighting with LEDs: Evaluation of lighting damage to contemporary photographic materials

It is possible to assess the damage to artworks by measuring different physical and chemical parameters. One of the most important parameters is colour difference, which is a consequence of chemical changes in the material. CIE 157:2004 ‘Control of Damage to Museum Objects by Optical Radiation’ classifies museum collections into four groups, according to different levels of light fastness. However, these classes were developed from research using traditional light sources. Even though LED technology is becoming more popular, there is no advanced evaluation of colour fading or a colour change test for contemporary artworks. This study established that the CIE 157:2004 method, based on threshold effective radiant exposure, can be applied to an actual ageing test of ultraviolet-blocked light sources including two types of white LEDs and one traditional halogen lamp. The results also present a colour fading model that can be used in museum LED lighting to predict the colour difference in contemporary photographic materials for short- and long-term exhibition. This study also provides a revised light dosage classification of modern photographic materials for museums. Moreover, the verification studies can be used as a conceptual reference for assessing the damage potential of other art materials under the tunable multi-LED system of the future.
