Questioning social solidarity through the perspective of parking violations in spaces reserved for disabled people
Authors: Bučar Ručman Aleš
Published: December 2019

Unjustified parking in parking spaces reserved for disabled people is a social phenomenon that reflects characteristics and attitudes concerning solidarity, morality, social norms and values. Disabled people’s entitlement to specific parking spaces stems from the general right to mobility, independence, self-realisation and autonomy. In research conducted in the capital city of Slovenia, observers monitored 72 parking spaces reserved for disabled people (on-street spaces, in shopping and health centres). Among all uses of these spaces 63.1% were violations, although in some locations this share exceeded 90%, and 29.3% of violations occurred while at least one unoccupied non-reserved space was available in the near vicinity. The violators parked their vehicles for a short time, with half remaining in or close to the car. Formal social control is closely connected with the domination of an organic type of solidarity. Yet, this research shows it has clear limitations. In just 12 hours of observing reserved parking spaces, the researchers managed to note down the equivalent of 38.5% of the total violations processed annually by municipal wardens. Although the research focuses on one specific issue of solidarity, its implications resound beyond this particular case and suggest broader societal reasons for changes in solidarity.
Katie Geneva Cannon Was a Waymaker
Authors: Williams Reggie L.
Published: December 2019

Faith must be guided by norms that emphasize justice, communal uplift, and collective well-being. A Christian concern for justice allows for vision that sees oppression and honors the image of God in the face of all of God’s children. The Rev. Dr. Cannon was a waymaker who helped figure that out.

Authors: Yu Hanwen , Sun Qun , Wang Chong , Zhao Yongjun
Published: December 2019

For the palletizing robot’s operating characteristics of high speed, high acceleration, and heavy load, it is necessary to make a research on the structure optimization focusing on the vibration characteristics according to the mechanical and dynamic performance analysis. This article first introduces the mechanical feature and working principle of high-speed and heavy-load robot palletizer. Kinematics analysis is carried out by using D-H parameter method, which obtains positive kinematics solution and workspace. Jacobian matrix is deduced, and the relationship between joint space and Cartesian space is established. Second, for the reason that joint flexibility has a great influence on the vibration performance of the robot, a rigid–flexible coupling dynamic model is established based on the simplified model of the flexible reducer and Lagrange’s second equation to describe the joint flexibility of high-speed and heavy-load palletizing robot, and the vibration modes of the robot are analyzed. The influence of different joint stiffness on the frequency response of the system reveals the inherent properties of the heavy-load palletizing robot, which provides a theoretical basis for the optimal design and control of the heavy-load palletizing robot.
Delayed Benefits: Effects of California School District Bond Elections on Achievement by Socioeconomic Status
Authors: Rauscher Emily
Published: December 2019

Contradictory evidence of the relationship between education funding and student achievement could reflect heterogeneous effects by revenue source or student characteristics. This study examines potential heterogeneous effects of a particular type of local revenue—bond funds for capital investments—on achievement by socioeconomic status. Comparing California school districts within a narrow window on either side of the cutoff of voter support required to pass a general obligation bond measure, I use dynamic regression discontinuity models to estimate effects of passing a bond on academic achievement among low- and high-socioeconomic-status (SES) students. Results consistently suggest that passing a bond increases achievement among low- but not high-SES students. However, these benefits for low-SES students are delayed and emerge six years after an election. Effects are larger in low-income districts and in small districts, where benefits of capital investments are experienced by a larger proportion of students.

Authors: Reyes Ganiva
Published: December 2019

Using portraiture methodology, this study features caring classroom experiences between Latina teen mothers and their teachers at an alternative school along the U.S./Mexico border. Classroom observations and in-depth interviews were conducted to piece together three classroom portraits which reveal the following: (a) authentically caring pedagogical interactions in the classrooms enabled Latina teen mothers to develop a pro-school ethos, and (b) these pedagogical interactions of care and support in the classroom were made possible within a caring schooling structure. This article contributes to the field of urban education by showcasing successes and effective practices in an urban setting.
Belonging and the intergenerational transmission of place identity: Reflections on a British inner-city neighbourhood
Authors: Frost Diane , Catney Gemma
Published: December 2019

This paper explores the subjectivities of neighbourhood identity and belonging. It considers how far, and in what ways, place identity and attachment are transmitted cross-generationally. Three broad themes have framed this research. First, the ways in which the formation and reproduction of neighbourhood identities have been influenced by geographical, political, contemporary and historical contexts. Second, and relatedly, the roles played by intersectional factors such as race and class. Third, the extent to which alternative neighbourhood identities challenge and contest ‘mainstream’ narratives that stigmatise and undermine disadvantaged inner-city communities. This paper draws on a case study area of ‘Liverpool 8’ (part of the wider Toxteth locale), a historically ethnically diverse inner-city area which attracted negative press coverage during the 1980s and 2011 riots. Drawing on a series of in-depth interviews with residents, the research reveals evidence of strong neighbourhood belonging and identity, shared and diffused across generations, based on subjective experiences, both positive (e.g. celebration of diversity, neighbourliness) and negative (e.g. racism, discrimination). To some extent, younger generation narratives reveal subtle changes that suggest a broadening of spatial horizons, beyond the residents’ immediate neighbourhood. However, at the same time, socio-economic and ethnic inequalities act to temper and stifle socio-spatial networks and experiences outside the immediate neighbourhood, for younger – as well as older – generations.
A new role for Balint groups in overcoming professional isolation and loneliness
Authors: Frey John J
Published: December 2019

Since its formal designation as a specialty in 1969, family medicine has embraced the concept of education in the doctor–patient relationship grounded in the principles of continuity and comprehensive care of families. As such, the influence of Balint groups on education has been ongoing and persistent, despite the vagaries of changing structures for education. However, in the United States, the focus has been heavily in resident education. As medicine has fragmented into narrow venues such as hospital care, urgent care, and subspecialty care in family medicine, physicians have become more disconnected physically and isolated from each other. Balint trained leaders and Balint groups—whether following the formal structure of traditional groups or serving as a safe place for conversations about the struggles in medicine and the meaning of the profession—have the opportunity to help heal the professional loneliness and isolation of physicians. Leaders and clinicians need to demand support for this idea in large health systems.
Killing Me Softly: Organizational E-mail Monitoring Expectations’ Impact on Employee and Significant Other Well-Being
Authors: Becker William J. , Belkin Liuba Y. , Conroy Samantha A. , Tuskey Sarah
Published: December 2019

This paper tests the relationship between organizational expectations to monitor work-related electronic communication during nonwork hours and the health and relationship satisfaction of employees and their significant others. We integrate resource-based theories with research on interruptions to position organizational expectations for e-mail monitoring (OEEM) during nonwork time as a psychological stressor that elicits anxiety due to employee attention allocation conflict. E-mail–triggered anxiety, in turn, negatively affects the health and relationship quality of employees and their significant others. We conducted three studies to test our propositions. Using the experience sampling method with 108 working U.S. adults, Study 1 established within-employee effects of OEEM on anxiety, employee health, and relationship conflict. Study 2 used a sample of 138 dyads of full-time employees and their significant others to replicate detrimental health and relationship effects of OEEM through anxiety. It also showed crossover effects of OEEM on partner health and relationship satisfaction. Finally, Study 3 employed a two-wave data collection method with an online sample of 162 U.S. working adults to provide additional support for the OEEM construct as a distinct and reliable job stressor and replicated findings from Studies 1 and 2. Taken together, our research extends the literature on work-related electronic communication at the interface of work and nonwork boundaries, deepening our understanding of the impact of OEEM on employees and their families’ health and well-being.
Apprenticing the jazz performer through ensemble collaboration: A qualitative enquiry
Authors: de Bruin Leon R , Williamson Paul , Wilson Emily
Published: December 2019

The one-to-one teacher–student relationship is a common learning configuration within jazz education. However, opportunities to learn through engagement in ensemble performances and industry-level recording opportunities with esteemed jazz performers are rare classroom environments the tertiary jazz music institutions offer. This qualitative study examines ‘real-world’ jazz performance contexts within an Australian tertiary music course, exploring students’ learning experience spanning three diverse collaborative projects. Bandura’s Social Cognition Theory is utilized to elucidate an ecological system of musical development, where learning occurs in a social context within dynamic, reciprocal interactions between learners, environment and students’ adaptive behaviours that are bounded by context, culture and learner history. Findings from pre- and post-participation interviews reveal student and educator perspectives of engaging in authentic experiential learning situations. A stratum of positive influences impacting students included metacognitive, behavioural, emotional affordances, as well as the cultivation of a wider social, environmental and cultural/creative confidence and an expanding collaborative community influencing individuals’ learning decisions. Students and educator participants expressed professional-level expectations, real-world outcomes, and a deeper musical connection and understanding by students of the guest artist/composers’ intention, musical aesthetic and expert band direction. The authors maintain that inclusion of experience-based education and embedding of authentic professional industry experience and creative music-making contexts within educational settings enhance the learning of students and potentially enculturate richer musicianship in students and their developing creative communities.
“My voice speaks for itself”: The experiences of three transgender students in American secondary school choral programs
Authors: Palkki Joshua
Published: December 2019

With the purpose of furthering lesbian, gay, bisexual, transgender, queer, questioning, and allies/agender/asexual (LGBTQA) dialogue in music education and to improve choral instruction for trans(gender) students, this multiple narrative case study explores the experiences of trans students in secondary school choral music programs in the United States. The emergent research design employed narrative and ethnographic techniques to honor and highlight voices of the three participants. The connection or lack thereof between voice and gender identity was different for each student. The policies of the students’ school districts, school officials, choral programs, and state music organizations shaped and influenced the participants as they navigated their trans identity within the high school choral context. Mentors (including teachers) and other “important others” helped these students as they traversed their gender journeys. From this research, it emerges that schools and choral programs can make policy changes to better serve trans youth, and more professional development and incorporation of (trans)gender issues is necessary for choral music educators.
Assessing the effect of sugar-free chewing gum use on the residual gastric volume of patients fasting for gastroscopy: A randomised controlled trial
Authors: Best Gregg WJ , Fanning Scott B , Robertson Iain K , Blackford Dane , Mitchell Brent L
Published: December 2019

There is no clear consensus in the current guidelines published by major international anaesthetic associations on what is the most appropriate time for a patient to stop chewing gum. This open-label balanced-group randomised controlled trial aimed to evaluate whether the chewing of sugar-free gum caused an increased volume or reduced pH of residual gastric fluid in fasting patients. For this study 212 patients undergoing elective gastroscopy were randomised into a control group who followed routine fasting instructions and an intervention group who were asked to chew gum while fasting. Residual gastric fluid was aspirated under direct vision via a gastroscope under anaesthesia. The primary outcome was the incidence of a gastric residual volume >50 ml in participants who chewed gum compared with a control group. Secondary outcomes were variability in the overall gastric volume distribution and gastric pH distribution between the two groups. Nine out of 110 (8.2%) in the chewing gum group and six out of 102 (5.9%) in the control group had a residual gastric fluid volume >50 ml: incidence rate ratio 1.39 (95% confidence intervals (CI) 0.51–3.77; P = 0.60). However, only one patient (in the control group) had a residual gastric volume >73 ml. There was no statistically significant difference in gastric volume distribution between groups, odds ratio 1.60 (95% CI 0.99–2.58; P = 0.054) or in the distribution of gastric pH measurement, odds ratio 0.90 (95% CI 0.57–1.44; P = 0.67). These results indicate that if there is an increase in the incidence of residual gastric volume >50 ml in patients who chew gum preoperatively, it is likely to be small. Moreover, the absence of any patients in our chewing gum group with a residual gastric volume >73 ml is reassuring.

Authors: Wattanawong Nissapa , Chatchaipaiboon Kanchana , Sreekirin Natchanan , Aht-Ong Duangdao
Published: December 2019

Bacterial growth on food is a main factor in the reduction of food quality, leading to short-term food shelf life. Development of antibacterial packaging can inhibit the bacterial growth and extend food shelf life. Silver loaded zeolite was used as the antibacterial agent in this work. Three zeolites (different Si/Al ratio) such as zeolite A, zeolite Y, and zeolite Socony Mobil-5 (ZSM-5) incorporating with the same silver content were prepared. The characterization was carried out by energy dispersive X-ray spectroscopy, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, nitrogen adsorption, and color analysis. Antibacterial activity of the three silver zeolites was tested against Escherichia coli and Staphylococcus aureus. Silver loaded zeolite ZSM-5 showed better bacterial inhibition than silver incorporated zeolite A and Y. For composite film preparation, silver loaded zeolite ZSM-5/poly(butylene succinate) composite films were prepared by varying silver loaded zeolite ZSM-5 concentrations and characterized by different techniques (mechanical test, scanning electron microscopy, and color analysis). Poly(butylene succinate) composite films filled with silver loaded zeolite ZSM-5 showed 99.9% of bacterial reduction within 24 h, indicating the effective antibacterial activity. From the silver migration results, the silver release from poly(butylene succinate) films was less than the limitation of European Food Safety Authority regulation, indicating the safety for food packaging applications.
Optical and thermal studies of modified terephthaldehyde–acetone polymer
Authors: Mazhar Sana , Ahmad Zahoor , Akhtar Tashfeen
Published: December 2019

Terephthaldehyde–acetone polymer was synthesized in an attempt to study its different structural and spectroscopic aspects along with thermal stability. The effect of modification was studied by introducing 4,5-dihydro-1 H-pyrazole ring in the polymer chain and silver nano particles (Ag NPs). The structural features of the polymer are supported by scanning electron microscope (SEM), Fourier transform infrared, and X-ray diffraction (XRD) studies. The modification of the polymer is indicated by the appearance of new absorption bands in infrared spectra, due to the formation of dihydropyrazole ring and the interaction of Ag NPs with the main chain of the polymer. XRD revealed the amorphous polymer with an improved degree of crystallinity in the case of nanocomposites. The polymer was found thermally stable up to 210°C, and the stability improved by the addition of 4,5-dihydro-1 H-pyrazole (325°C) and Ag NPs (up to 360°C). The polymer looks fibrous in SEM micrographs and a decrease in this character is observed on modification. The optical and fluorescence properties warrant its use in LEDs and as an ultraviolet absorber.
Christ and the Church: Ephesians 4:8–10 as a Test of Theological Exegesis
Authors: Brain Michael
Published: December 2019

Historical criticism often lacks the information required to determine the meaning of a biblical text, requiring readers of Scripture to engage with other interpretive approaches. Using Ephesians 4:8–10 as an example, this article demonstrates how theological interpretation, by bracketing out historical questions and examining scriptural figures and typologies, brings coherence to texts where historical criticism falls short. The article compares historical-critical interpretations of Ephesians 4 with patristic and medieval readings. Where historical-critical scholars have been unable to discern the precise meaning of the text, pre-critical readers understood it as having multiple meanings, each one cohering within the unity of the gospel narrative. Using this insight, the article offers a theological interpretation of Eph. 4, unifying the various interpretations in their common reference to the gospel, depicted as a story of Christ’s humiliation and exaltation.

Whoever thinks that in this mortal life a person may so dispense the mists of bodily and carnal imaginings as to possess the unclouded light of changeless truth, and cleave to it with the unswerving constancy of a spirit wholly estranged from the common ways of this life — he understands neither what he seeks nor what he is that seeks it (Augustine, De Consensu Evangelistorum, IV.20).
Engaging Customer Cocreation in New Product Development Through Foreign Subsidiaries: Influences of Multinational Corporations’ Global Integration and Local Adaptation Mechanisms
Authors: Leung Fine F. , Tse Caleb H. , Yim Chi Kin (Bennett)
Published: December 2019

Efforts to engage customers in cocreating new products have garnered much research attention from studies documenting customer cocreation’s (CC’s) positive impact on firm innovation and performance. Less research, however, has counterbalanced the bright side with the potential dark side of CC, especially as a strategy for multinational corporations (MNCs) operating in foreign markets. This study examines how MNC subsidiaries’ CC affects new product innovativeness and knowledge leakage to competitors. Adopting a broader agency perspective to recognize that subsidiaries often do not perform up to headquarters’ expectations due to both self-serving opportunism and honest incompetence, this study explores how CC effects are contingent on MNCs’ global management mechanisms. Using a dyadic managerial survey of 238 MNC subsidiaries, the authors find that MNCs can control knowledge leakage by implementing proper global integration and local adaptation mechanisms. However, CC may not improve new product innovativeness, except when the subsidiary has low local research-and-development staff influence. This study contributes to the CC literature by showing its benefits, challenges, and boundary conditions as a growing MNC innovation strategy.
Motivational Interviewing in Child Welfare Services: A Systematic Review
Authors: Hall Martin T. , Sears Jeanelle , Walton Matthew T.
Published: December 2019

Families in the child welfare (CW) system who cannot be engaged in services are at high risk of negative outcomes. As motivational interviewing (MI) has been shown to improve engagement in similar contexts. This study aimed to systematically review MI with CW families as well as MI training with CW workers and social work students training to become CW workers. The review used Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched multiple databases in June 2018. In September 2019, the initial search was repeated with additional searches to identify gray literature. Eight studies described the acquisition of MI among CW workers or student trainees, and 11 studies evaluated the impact of MI on families in CW. MI’s impact on some family outcomes, such as engagement in services, was mixed, though MI paired with other evidence-based treatments showed positive effects. With regard to training CW workers and students in MI, differences in training duration, intensity, and modality make conclusions difficult, though trainees generally described MI favorably and some studies showed training increased worker empathy and self-efficacy. Importantly, few published studies have evaluated whether MI-trained CW workers impact out-of-home-care placement, and no studies have evaluated their impact on maltreatment.

Authors: Ragnarsson Susanne , Johansson Klara , Bergström Erik , Sjöberg Gunnar , Hurtig Anna-Karin , Petersen Solveig
Published: December 2019

Aims: The overall aim was to explore the relationship between recurrent pain and perceived problems with academic achievement among boys and girls in middle and late elementary school. Methods: This 3-year follow-up study was based on data from the Study of Health in School-aged Children from Umeå (Sweden) and included children attending grade 6 in years 2003 and 2006, and a follow-up 3 years later in grade 9 ( n = 1524, participation rate 90%). Results: Recurrent pain (head, stomach or back) at least doubled the odds of concurrent- and subsequent perceived problems with academic achievement. This applied for pain on a monthly and weekly basis, from single and multiple sites, and from each of the three studied pain sites. The odds increased with increasing pain frequency and number of pain sites. Problems with sleep, concentration or school absenteeism did not explain the association. Conclusions: Recurrent pain seems to be a potential predictor of perceived problems with academic achievement for school-aged children. This emphasises the importance of early identification and prevention of recurrent pain problems.
Identification of lncRNA, MicroRNA, and mRNA-Associated CeRNA Network of Radiation-Induced Lung Injury in a Mice Model

Published: December 2019

Radiation-induced lung injury (RILI) can be challenging for thoracic radiotherapy, thus investigating its mechanisms of related pathophysiological process is needed. Long noncoding RNAs (lncRNAs) was found to participate in normal tissue damage induced by ionizing irradiation. Here, we first profiled the dysregulation of lncRNAs, microRNAs (miRNAs), and messenger RNAs (mRNAs) of RILI in mice model receiving 12 Gy thoracic irradiation. The lung tissue was collected 48 hours after irradiation, after which an RNA library was built by RNA sequencing. Compared with the control group, 461 mRNAs and 401 lncRNAs were significantly upregulated, while 936 mRNAs and 501 lncRNAs were significantly downregulated. Then we predicted target miRNAs of the dysregulated lncRNAs and the target mRNAs of these miRNAs. Next, functional annotations of these target mRNAs were performed. Results showed some pathways apparently dysregulated, such as Th1 and Th2 cell differentiation, Th17 cell differentiation, and hematopoietic cell lineage. Through this study, we also highlighted that T helpers could be vital in RILI through lncRNA-miRNA-mRNA network, therefore causing fibrosis, indicating that RNA dysregulation in early stage of RILI may cause severe late complications. Thus, research on the target mechanism and early intervention of lncRNAs with associated competing endogenous RNA network will benefit the treatment of RILI.
Convolutional neural network-based coarse initial position estimation of a monocular camera in large-scale 3D light detection and ranging maps
Authors: Sun Manhui , Yang Shaowu , Liu Hengzhu
Published: December 2019

Initial position estimation in global maps, which is a prerequisite for accurate localization, plays a critical role in mobile robot navigation tasks. Global positioning system signals often become unreliable in disaster sites or indoor areas, which require other localization methods to help the robot in searching and rescuing. Many visual-based approaches focus on estimating a robot’s position within prior maps acquired with cameras. In contrast to conventional methods that need a coarse estimation of initial position to precisely localize a camera in a given map, we propose a novel approach that estimates the initial position of a monocular camera within a given 3D light detection and ranging map using a convolutional neural network with no retraining is required. It enables a mobile robot to estimate a coarse position of itself in 3D maps with only a monocular camera. The key idea of our work is to use depth information as intermediate data to retrieve a camera image in immense point clouds. We employ an unsupervised learning framework to predict the depth from a single image. Then we use a pretrained convolutional neural network model to generate depth image descriptors to construct representations of the places. We retrieve the position by computing similarity scores between the current depth image and the depth images projected from the 3D maps. Experiments on the publicly available KITTI data sets have demonstrated the efficiency and feasibility of the presented algorithm.
Customer acceptance of mobile marketing in Jordan: An extended UTAUT2 model with trust and risk factors

Published: December 2019

While mobile marketing is widely practised in developed countries, this is not always the case for developing countries, such as Jordan, where the acceptance level for mobile marketing remains low. This study aims to uncover the predictors for the behaviour of Jordanian customers with regard to the acceptance of mobile marketing. For this purpose, a questionnaire based on quantitative research was conceived. This investigation involved the unified theory of acceptance and use of technology (UTAUT2), which was extended to include two additional variables: ‘trust’ and ‘risk’. For the empirical testing of the model, data was collected from 321 respondents, and the hypotheses were tested through variance-based structural equation modelling. SmartPLS 3.0 was used to analyse the data. The findings from this study suggest that performance expectancy, effort expectancy, hedonic motivation, social influence, price value, facilitating conditions, habit and risk significantly influence the behavioural intention of customers regarding the adoption of mobile marketing. On the other hand, the trust factor was found to be an insignificant predictor in this area.
Youth Gaming Addiction: Implications for School Nurses
Authors: Johnson Jennifer Leigh , Edwards Phillip Matthew
Published: December 2019

Technology is pervasive in society and reaches across all age-groups. The use of technology in youth has risen steadily in the past two decades through access to television, internet, computers, social media, and gaming in various formats. Due to this increased exposure and access, concerns have developed among mental health and healthcare providers regarding gaming addiction in youth. The American Psychiatric Association mentioned internet gaming disorder in the 2013 publication of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.). While not recognized as a specific diagnosis at the time of publication, there was a call for further research and evaluation of this phenomenon. Research indicates there are negative impacts on academic performance, social development, and self-concept in game-addicted youth. The purpose of this article is to provide the school nurse with information needed to recognize and care for youth at risk for and those experiencing gaming addiction. The school nurse is poised to provide nursing care in the school setting to educate, prevent, and help manage youth with gaming addiction risks and experiences, as part of an interdisciplinary team.
Unicameral bone cyst in the pelvis: report of a case treated by placement of screws made from a composite of unsintered hydroxyapatite particles and poly-l-lactide
Authors: Sakamoto Akio , Okamoto Takeshi , Matsuda Shuichi
Published: December 2019

Unicameral bone cysts are fluid-filled benign lesions that occur mostly in the long bones. Unicameral bone cysts in the pelvis are extremely rare. Continuous decompression using titanium or hydroxyapatite screws has been reported as a treatment. Screws made from a composite of unsintered hydroxyapatite particles and poly-l-lactide can be used for the treatment. An adolescent male patient presented with a unicameral bone cyst in the ilium extending to a region adjacent to the hip joint. As initial treatment, the cortex was fenestrated when the patient was 13 years old and β-tricalcium phosphate implanted. The cyst first reoccurred when the patient was 15 years old and again when he was 17 years old. During the most recent treatment, unsintered hydroxyapatite particles and poly-l-lactide composite screws were placed, and no recurrence was observed during 2 years of follow-up. The slow biodegradability and absorbability of the screws may allow continuous drainage of unicameral bone cysts.

Published: December 2019

Introduction

Parents of children with autism spectrum disorder often experience high levels of stress and challenges when organizing medical and behavioral services for their child. Care coordination could alleviate these challenges, however little is known about the effectiveness of this service. This study examined the need, feasibility, and acceptability of a care coordination program.

Methods

Families of 176 children with autism, seen at a multidisciplinary autism clinic in the United States, participated in a prospective observational study. Families received a three-month structured care coordination program and completed pre- and post-program questionnaires that probed parents’ beliefs about the need and acceptability of the program through structured and open-ended questions.

Results

Most (≥90%) parents reported both a need for care coordination and satisfaction with the program. Qualitative themes identified valuable aspects and ways to improve the program.

Discussion

Parents raising a child with autism spectrum disorder experience an unmet need for care coordination. When provided, parents’ demonstrated high uptake of service and high levels of satisfaction with the program.
Transition Planning: Keeping Cultural Competence in Mind
Authors: Suk Andrea L. , Sinclair Tracy E. , Osmani Kimberly J. , Williams-Diehm Kendra
Published: December 2019

Transition planning must consider all aspects of the student’s postsecondary goals. Although the makeup of personnel in educational settings are predominantly White, the number of students from culturally, ethnically, and linguistically diverse (CELD) backgrounds continues to grow. This article promotes personal reflection on cultural competence, suggests how to incorporate cultural responsiveness into transition planning, and recommends how special educators can develop strong, compliant transition goals for students from CELD backgrounds.
Anatomical sacral slope, a new pelvic parameter, is associated with lumbar lordosis and pelvic incidence in healthy Japanese women: A retrospective cross-sectional study
Authors: Suzuki Hayato , Imai Norio , Nozaki Asami , Hirano Yuki , Endo Naoto
Published: December 2019

Purpose:

Anatomical sacral slope (a-SS), a pelvic anatomical parameter that does not require the center of the femoral head, strongly correlates with pelvic incidence (PI) during three-dimensional measurements in normal subjects. Sagittal alignment of spinal and pelvic parameters is typically evaluated using two-dimensional radiographs; however, the relationship between a-SS and PI has not been evaluated using radiographs. This study aimed to evaluate the correlation between a-SS and other spinal and pelvic parameters using radiographs.

Methods:

We evaluated 144 healthy women. Using sagittal radiographs, we measured lumbar lordosis (LL), thoracic kyphosis, PI, SS, pelvic tilt, and a-SS, which were defined as the angle between the superior end plate of S1 and a line perpendicular to the anterior pelvic plane. Pearson coefficients were used to determine correlations, and intraobserver and interobserver intraclass correlation coefficients (ICCs) were used for validation.

Results:

There was a strong correlation between PI and a-SS ( r = 0.756). Moreover, correlations between a-SS and LL and between PI and LL were similar ( r = 0.661 and r = 0.554, respectively). The intraobserver ICCs were 0.884 for a-SS and 0.840 for PI. The interobserver ICCs were 0.856 for a-SS and 0.653 for PI.

Conclusion:

a-SS was strongly correlated with PI. The correlation between a-SS and LL was equivalent to the correlation between PI and LL. Moreover, the ICC for a-SS was larger than that of PI. This study suggests that a-SS is a useful new pelvic anatomical parameter that can be used instead of PI.

Published: December 2019

Purpose:

To examine the results of medial open-wedge high tibial osteotomy (MOWHTO) combined with all-inside repair focusing on medial meniscus posterior root tears (MMPRT) by second-look arthroscopy and determine the clinical relevance of the findings.

Methods:

From June 2015 to June 2017, 27 consecutive patients underwent MOWHTO and meniscal treatment for MMPRT using all-inside repair. All were available for second-look arthroscopy evaluation at the time of plate removal. Cartilage regeneration in the medial condyles and healing status of the MMPRT were assessed at the time of second-look arthroscopy. Clinical outcomes were evaluated by the Hospital for Special Surgery (HSS) scores and the Lysholm score scale. The potential factors affecting the healing of MMPRT, including age, body mass index (BMI), weight-bearing line rate (WBLR) and femorotibial angle (FTA) were discussed.

Results:

There were 11 (41%) cases with complete healing (group A) and 16 (59%) cases with lax healing (group B). A complete cartilage coverage of chondral lesions was observed at second-look arthroscopy. Improvements of HSS in both groups were 41.25 ± 6.18 and 38.82 ± 5.43, while improvements in Lysholm score seen in both groups were 30.40 ± 4.84 and 32.65 ± 4.11. There was no significant difference in the postoperative clinical results between the two groups. In group A, the age (months), BMI, WBLR, and FTA are 54.61 ± 2.53, 23.58 ± 2.39, 66.10 ± 2.86% and 169.00 ± 2.62°, respectively, while in group B, they are 55.16 ± 4.92, 29.58 ± 3.91, 57.51 ± 5.49% and 175.21 ± 2.87°, respectively. A significant difference has been identified between two groups except for age.

Conclusion:

As seen in this retrospective study, a higher healing rate of MMPRT using all-inside repair and regeneration of degenerated articular cartilage in the medial condyles after MOWHTO can be expected. Healing of the MMPRT was not related to a better clinical outcome. Moreover, it can be inferred that BMI, WBLR and FTA may affect the healing status of MMPRT.

In this work, a high-density hydrogen (HDH) treatment is proposed to reduce interface traps and enhance the efficiency of the passivated emitter rear contact (PERC) device. The hydrogen gas is compressed at pressure (~ 70 atm) and relatively low temperature (~ 200 °C) to reduce interface traps without changing any other part of the device’s original fabrication process. Fourier-transform infrared spectroscopy (FTIR) confirmed the enhancement of Si–H bonding and secondary-ion mass spectrometry (SIMS) confirmed the SiN/Si interface traps after the HDH treatment. In addition, electrical measurements of conductance-voltage are measured and extracted to verify the interface trap density (Dit). Moreover, short circuit current density (Jsc), series resistance (Rs), and fill factor (F.F.) are analyzed with a simulated light source of 1 kW M−2 global AM1.5 spectrum to confirm the increase in cell efficiency. External quantum efficiency (EQE) is also measured to confirm the enhancement in conversion efficiency between different wavelengths. Finally, a model is proposed to explain the experimental result before and after the treatment.

Background

Targeted therapy for non-small cell lung cancer is histology dependent. However, histological classification by routine pathological assessment with hematoxylin-eosin staining and immunostaining for poorly differentiated tumors, particularly those from small biopsies, is still challenging. Additionally, the effectiveness of immunomarkers is limited by technical inconsistencies of immunostaining and lack of standardization for staining interpretation.

Results

Using gene expression profiles of pathologically-determined lung adenocarcinomas and squamous cell carcinomas, denoted as pADC and pSCC respectively, we developed a qualitative transcriptional signature, based on the within-sample relative gene expression orderings (REOs) of gene pairs, to distinguish ADC from SCC. The signature consists of two genes,KRT5andAGR2, which has the stable REO pattern ofKRT5 > AGR2in pSCC andKRT5 < AGR2in pADC. In the two test datasets with relative unambiguous NSCLC types, the apparent accuracy of the signature were 94.44 and 98.41%, respectively. In the other integrated dataset for frozen tissues, the signature reclassified 4.22% of the 805 pADC patients as SCC and 12% of the 125 pSCC patients as ADC. Similar results were observed in the clinical challenging cases, including FFPE specimens, mixed tumors, small biopsy specimens and poorly differentiated specimens. The survival analyses showed that the pADC patients reclassified as SCC had significantly shorter overall survival than the signature-confirmed pADC patients (log-rankp = 0.0123, HR = 1.89), consisting with the knowledge that SCC patients suffer poor prognoses than ADC patients. The proliferative activity, subtype-specific marker genes and consensus clustering analyses also supported the correctness of our signature.

Conclusions

The non-subjective qualitative REOs signature could effectively distinguish ADC from SCC, which would be an auxiliary test for the pathological assessment of the ambiguous cases.
Long noncoding RNAs in lipid metabolism: literature review and conservation analysis across species

Published: December 2019

Background

Lipids are important for the cell and organism life since they are major components of membranes, energy reserves and are also signal molecules. The main organs for the energy synthesis and storage are the liver and adipose tissue, both in humans and in more distant species such as chicken. Long noncoding RNAs (lncRNAs) are known to be involved in many biological processes including lipid metabolism.

Results

In this context, this paper provides the most exhaustive list of lncRNAs involved in lipid metabolism with 60 genes identified after an in-depth analysis of the bibliography, while all “review” type articles list a total of 27 genes. These 60 lncRNAs are mainly described in human or mice and only a few of them have a precise described mode-of-action. Because these genes are still named in a non-standard way making such a study tedious, we propose a standard name for this list according to the rules dictated by the HUGO consortium. Moreover, we identified about 10% of lncRNAs which are conserved between mammals and chicken and 2% between mammals and fishes. Finally, we demonstrated that two lncRNA were wrongly considered as lncRNAs in the literature since they are 3′ extensions of the closest coding gene.

Conclusions

Such a lncRNAs catalogue can participate to the understanding of the lipid metabolism regulators; it can be useful to better understand the genetic regulation of some human diseases (obesity, hepatic steatosis) or traits of economic interest in livestock species (meat quality, carcass composition). We have no doubt that this first set will be rapidly enriched in coming years.
Challenges of one-year longitudinal follow-up of a prospective, observational cohort study using an anonymised database: recommendations for trainee research collaboratives
Authors:   STARSurg Collaborative, Nepogodiev Dmitri
Published: December 2019

Background

Trainee research collaboratives (TRCs) have pioneered high quality, prospective ‘snap-shot’ surgical cohort studies in the UK. Outcomes After Kidney injury in Surgery (OAKS) was the first TRC cohort study to attempt to collect one-year follow-up data. The aims of this study were to evaluate one-year follow-up and data completion rates, and to identify factors associated with improved follow-up rates.

Methods

In this multicentre study, patients undergoing major gastrointestinal surgery were prospectively identified and followed up at one-year following surgery for six clinical outcomes. The primary outcome for this report was the follow-up rate for mortality at 1 year. The secondary outcome was the data completeness rate in those patients who were followed-up. An electronic survey was disseminated to investigators to identify strategies associated with improved follow-up.

Results

Of the 173 centres that collected baseline data, 126 centres registered to participate in one-year follow-up. Overall 62.3% (3482/5585) of patients were followed-up at 1 year; in centres registered to collect one-year outcomes, the follow-up rate was 82.6% (3482/4213). There were no differences in sex, comorbidity, operative urgency, or 7-day postoperative AKI rate between patients who were lost to follow-up and those who were successfully followed-up. In centres registered to collect one-year follow-up outcomes, overall data completeness was 83.1%, with 57.9% (73/126) of centres having ≥95% data completeness. Factors associated with increased likelihood of achieving ≥95% data completeness were total number of patients to be followed-up (77.4% in centres with < 15 patients, 59.0% with 15–29 patients, 51.4% with 30–59 patients, and 36.8% with > 60 patients, p = 0.030), and central versus local storage of patient identifiers (72.5% vs 48.0%, respectively, p = 0.006).

Conclusions

TRC methodology can be used to follow-up patients identified in prospective cohort studies at one-year. Follow-up rates are maximized by central storage of patient identifiers.
