Мета: виявити ризик розвитку захворювань в осіб молодого віку за показником індивідуального сприйняття часу.

Матеріали і методи. Проведено анкетування 200 осіб жіночої та чоловічої статей віком від 18 до 22 років (по 100 осіб у кожній групі) для виявлення факторів ризику та визначення показника індивідуального сприйняття часу (τ) за методом Б. Й. Цуканова. В анкеті згруповано питання щодо факторів ризику патології серцево-судинної системи, сечовидільної системи, шлунково-кишкового тракту.

Результати. У осіб чоловічої статі із τ=0,7–0,8 є більший ризик захворіти на хвороби шлунково-кишкового тракту, оскільки вони частіше і в більшій кількості вживають алкоголь, частіше мають надлишкову масу тіла та піддаються стресовим впливам. Ймовірно більший ризик розвитку артеріальної гіпертензії при τ=0,8–0,86 існує в осіб жіночої статі. У осіб чоловічої статі з τ=0,86–0,94 більший ризик розвитку ниркової патології порівняно із особами жіночої статі, тому що вони зазнають частішого переохолодження та вживають більше води, тим самим збільшуючи навантаження на нирки. Більша схильність до гіподинамії, переважання тютюнокуріння, споживання надлишку солоної їжі та достовірно обтяжений спадковий анамнез щодо серцево-судинної патології при τ=0,94–1,00 у осіб чоловічої статі свідчить про високий ризик розвитку в них у майбутньому патології серцево-судинної системи (ішемічної хвороби серця та цереброваскулярних захворювань).

Висновки. Отримані результати вказують на наявність зв’язку певних факторів ризику розвитку захворювань з τ-типом респондентів. Визначення у подальшому в пацієнтів τ-типу дозволить спрогнозувати ризик розвитку певної патології та запропонувати їм комплекс індивідуальних профілактичних заходів.
First record of Cynipidae from Myanmar with description of a new species of Lithosaphonecrus (Hymenoptera: Cynipidae: Synergini)
Authors: IDE TATSUYA , AUNG MU MU , TANAKA NOBUYUKI
Published: July 2020

A new cynipid species, Lithosaphonecrus mindatus Ide, Aung & Tanaka, sp. nov., is described from Chin State, northwestern Myanmar. This is the first record of Cynipidae from this country. The new species emerged from a bud gall of Lithocarpus thomsonii. The new species’ morphological features closely resemble L. arcoverticus Liu, Zhu & Pang, but differ from the latter due to the presence of a broad foveal septum on the mesoscutellum and short triangular median mesoscutal impression and absence of the anteroadmedian signum on the mesoscutum. Partial sequences of cytochrome c oxidase subunit I region (614 bp) show a 14–15% difference between the new species and other congeners.

Authors: Liu Shiqing , Cheng Lili , Qi Wenxu , Zhang Xin , Dong Youjing
Published: July 2020

Objectives:

To measure the dimensions of the cricoid cartilage in adults and to investigate the age-related change of the dimensions of the cricoid cartilage.

Methods:

After performing the multiplanar reconstruction and correcting the slant of the cervical computed tomography scans, the transverse and anteroposterior internal diameters of the inlet (TD-in and APD-in) and outlet (TD-out and APD-out) of the cricoid cartilage were measured, respectively. The angle between the arch and lamina of the cricoid cartilage in the middle sagittal plane was measured. The ratios of transverse to anteroposterior diameter for the inlet (Ratio-in) and outlet (Ratio-out) of the cricoid cartilage were calculated, respectively.

Results:

A total of 1200 adults were included in this study, with 600 males and 600 females. The TD-in is the smallest cricoid diameter and the APD-in is the largest cricoid diameter. The mean cricoid diameters and the cricoid angle in males were larger than those in females. The cricoid inlet is oval shaped and the cricoid cartilage is “funnel-shaped” in the middle sagittal plane. The shape of the outlet of the cricoid cartilage varies greatly among individuals. In males, the APD-in and APD-out were negatively correlated with age while the Ratio-in and Ratio-out was positively correlated with age. In females, the APD-out were negatively correlated with age while the Ratio-out was negatively correlated with age.

Conclusions:

The dimensions of the cricoid cartilage change as age advances in adult population and the sexual dimorphism of the cricoid outlet occurs after 50 years old.
Collaborative Sustainable Business Models: Understanding Organizations Partnering for Community Sustainability
Authors: Ordonez-Ponce Eduardo , Clarke Amelia C. , Colbert Barry A.
Published: July 2020

Cross-sector social partnerships (CSSPs) are relevant units of analysis for understanding sustainable business models (SBMs). This research examines how organizations value their motivations to participate in large sustainability-focused partnerships, how they perceive the value captured, and their structures implemented to address sustainability partnerships. Two hundred and twenty-four organizations partnering within four large sustainability CSSPs were surveyed using an augmented resource-based view (RBV) theoretical framework. Results show that partners were motivated by and captured value related to sustainability-, organizational-, and human-oriented resources, and that organizations prefer more informal than formal structural elements to implement their partnerships’ sustainability strategies. Contributions to SBM and CSSP fields are revealed. SBM thinking is a provocation toward seeking integrated sustainable value creation, helping show the value of large CSSPs. Conversely, by conceiving of large, pluralistic CSSPs as “collaborative SBMs,” we extend the idea of the “business model” to the societal level, exploring how value is captured in partnership.
Disaster Ergonomics: Human Factors in COVID-19 Pandemic Emergency Management
Authors: Sasangohar Farzan , Moats Jason , Mehta Ranjana , Peres S. Camille
Published: July 2020

Objective

We aimed to identify opportunities for application of human factors knowledge base to mitigate disaster management (DM) challenges associated with the unique characteristics of the COVID-19 pandemic.

Background

The role of DM is to minimize and prevent further spread of the contagion over an extended period of time. This requires addressing large-scale logistics, coordination, and specialized training needs. However, DM-related challenges during the pandemic response and recovery are significantly different than with other kinds of disasters.

Method

An expert review was conducted to document issues relevant to human factors and ergonomics (HFE) in DM.

Results

The response to the COVID-19 crisis has presented complex and unique challenges to DM and public health practitioners. Compared to other disasters and previous pandemics, the COVID-19 outbreak has had an unprecedented scale, magnitude, and propagation rate. The high technical complexity of response and DM coupled with lack of mental model and expertise to respond to such a unique disaster has seriously challenged the response work systems. Recent research has investigated the role of HFE in modeling DM systems’ characteristics to improve resilience, accelerating emergency management expertise, developing agile training methods to facilitate dynamically changing response, improving communication and coordination among system elements, mitigating occupational hazards including guidelines for the design of personal protective equipment, and improving procedures to enhance efficiency and effectiveness of response efforts.

Conclusion

This short review highlights the potential for the field’s contribution to proactive and resilient DM for the ongoing and future pandemics.
The Impact of Advertising and R&D on Bankruptcy Survival: A Double-Edged Sword
Authors: Jindal Niket
Published: July 2020

Advertising and research and development (R&D) benefit firms by increasing sales and shareholder value. However, when a firm is in bankruptcy, the cumulative effects of its past advertising and R&D can be a double-edged sword. On the one hand, they increase the firm’s expected future cash flow, which increases the likelihood that the bankruptcy court will decide the firm can survive. On the other hand, they increase the liquidation value of the firm’s assets, which decreases the likelihood that the bankruptcy court will decide that the firm can survive. The author argues that the ability of advertising and R&D to either increase or decrease bankruptcy survival is contingent on the influence that the firm’s suppliers have, relative to other creditors, on the bankruptcy court’s decision. Advertising and R&D increase (decrease) bankruptcy survival when suppliers have a high (low) level of influence. Empirical analyses, conducted on 1,504 bankruptcies, show that advertising (R&D) increases bankruptcy survival when at least 35%−38% (18%−21%) of the bankrupt firm’s debt has been borrowed from suppliers, whereas it decreases bankruptcy survival below this point. Out-of-sample machine learning validation shows that the ability to predict whether a bankrupt customer will survive is substantially improved by considering the firm’s advertising and R&D.

Published: July 2020

Comparative analysis of the antibullfighting agenda in Bogotá, Lima, and Quito sheds light on the relation between new social movements and left parties. It suggests that, although a social movement is important to the visibility of the agenda, the key variable in achieving a ban on bullfighting in the three capitals has been a decisive left leadership that is not shy about confrontation with traditional elites.

Un análisis comparativo de la agenda contra la tauromaquia en Bogotá, Lima y Quito devela la relación entre los nuevos movimientos sociales y los partidos de izquierda. Sugiere que, aunque la existencia de un movimiento social resulta importante para visibilizar dicha agenda, la variable clave para lograr la prohibición de la tauromaquia en las tres capitales ha sido un liderazgo decisivo por parte de la izquierda, que no se ha mostrado tímida cuando se trata de confrontar a las élites tradicionales.

Published: July 2020

The present study was designed to examine shifting, the phenomenon of altering or modifying one’s self-presentation in different social contexts, as a mediator of the predictive effects of African American women’s acculturation on their perceived race-related stress. To explore this issue, measures of African American acculturation, shifting, and race-related stress were examined within a structural model. The current study quantitatively examined the relationships of these variables among a sample of 366 African American women. Results of a structural equation model indicated full mediation; greater levels of immersion in African American acculturation resulted in greater levels of shifting, which, in turn, generated increased levels of race-related stress. These data extend previous work and expand the literature regarding African American women’s shifting. Implications for clinical work and future research with African American women are also discussed.
Extended state observer-based finite-time dynamic surface control for trajectory tracking of a quadrotor unmanned aerial vehicle
Authors: Li Bo , Ban Hanyu , Gong Wenquan , Xiao Bing
Published: July 2020

This work presents a novel control strategy for the trajectory tracking control of the quadrotor unmanned aerial vehicle (UAV) with parameter uncertainties and external unknown disturbances. As a stepping stone, two fixed-time extended state observers (ESOs) are proposed to estimate the external disturbances and/or the parameter uncertainties for the position and attitude subsystems, respectively. Then, the fast terminal sliding mode-based improved dynamic surface control (DSC) approaches are developed. To eliminate the problem of “explosion of complexity” inherent in backstepping method-based controllers, the finite-time command filters and an error compensation signals are used in the design of the dynamic surface controllers. Subsequently, the practically finite-time stability of the closed-loop tracking system is guaranteed by utilizing the proposed control scheme. The simulation results are obtained to demonstrate the effectiveness and fine performance of the proposed trajectory tracking control approaches.

Published: July 2020

Orthodontics and periodontics have a sophisticated elaborate interdependence as every orthodontic intervention has a periodontal extent. Although orthodontic alignment promotes adequate plaque control, many detrimental effects on the periodontium may be observed during the treatment. Periodontal intervention is required at all stages of orthodontic therapy starting from orthodontist diagnosing a case to mid-treatment analysis of periodontium and also posttreatment investigation of the case. Many a time, successful orthodontic treatment is dependent on the overall maintenance of the health of the periodontium. On the other hand, orthodontic tooth alignment may be used as an adjunctive treatment in periodontally compromised patients. This review will help in better understanding of the orthodontic–periodontal interrelationship for the better framework of the treatment approach to bring out the optimum results in patients.
Age and Gender Invariance in the Taiwan Wechsler Intelligence Scale for Children, Fifth Edition: Higher Order Five-Factor Model
Authors: Chen Hsinyi , Zhu Jianjun , Liao Yung-Kun , Keith Timothy Z.
Published: July 2020

This study investigated the factorial invariance of the Taiwan Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) across age and gender. A higher order five-factor model was tested on a nationally representative sample of 1,034 children aged 6–16 years. The results demonstrated full factorial invariance for Taiwan children of different ages and gender. The WISC-V subtests demonstrated the same underlying theoretical latent constructs, strength of relations among factors and subtests, validity of each first-order factor, and communalities, regardless of age and gender, which supported the same interpretive approach of the WISC-V. These results accord with findings in the United States, indicating a full factorial invariance of the WISC-V five-factor structure across ages and gender.
Chinese University Students’ Attitudes Toward Rape Myth Acceptance: The Role of Gender, Sexual Stereotypes, and Adversarial Sexual Beliefs
Authors: Xue Jia , Lin Kai
Published: July 2020

The present study constructs and tests models that examine the relations between variables of “gender,” “sex role stereotyping,” and “adversarial sexual beliefs” on rape myth acceptance. The sample is 975 Chinese university students from seven universities in China. Measures include Chinese Rape Myth Acceptance (CRMA), Sex Role Stereotyping (SRS) Scale, and Adversarial Sexual Beliefs (ASB). We use structural equation modeling to investigate whether gender directly affects the acceptance of rape myth, or that these influences are mediated by SRS and ASB, after controlling for several demographic characteristics. Results suggest that SRS and ASB have a direct effect on rape myth acceptance. Gender has no direct effect on rape myth acceptance in three out of the four models, but it significantly (β = −.02, p < .05) predicts the acceptance of rape–violence myth. We also discuss the implications and limitations of the study.

Published: July 2020

We aimed to document in primary care older adults the relationship between family violence (FV) and mental and physical health, satisfaction with life, and health service use, by gender. The study sample included data from 1,658 older adults recruited in primary care practices, in one of the largest health regions in the province of Quebec. The presence of FV (partner/spouse, adult child) was assessed with the 21-item Family Violence Scale (FVS) adapted from the conflicts Tactics Scale 2. Self-rated mental health (SRMH) and self-rated physical health (SRPH) were assessed with single-item measures. Satisfaction with life (SWL) was measured using a validated French version of the SWL scale. Health service use over a 2-year period included outpatient consultations (number), emergency department (ED) visits (yes/no), and hospitalizations (yes/no). Multi-level logistic and Poisson’s regression models were conducted to assess study outcomes as a function of FV. Analyses were stratified by perpetrator and gender. There was an association between FV and SRMH in women (OR = 0.41, 95% CI = [0.27, 0.62]), and SWL in both men and women ( B = −5.74, 95% CI = [–6.71, –4.76]; B = −10.07, 95% CI = [–14.16, –5.98], respectively). Significant associations were found in women between FV and ED visits (OR = 1.45, 95% CI = [1.12, 1.18]), hospitalizations (OR = 1.36, 95% CI = [1.32, 1.43]), and outpatient consultations (RR = 1.25, 95% CI = [1.19, 1.30]). SWL moderated the association between FV and likelihood of hospitalization. Gender differences were observed between FV and SRMH and SWL. FV was associated with increased health service use in women but not men. These gender differences may suggest stigma-related barriers to health service use. Victims of violence with higher SWL had a lower likelihood of being hospitalized. Public health programs aimed at increasing awareness of the different types of FV and interventions aiming to improve resilience in victims are needed.

Published: July 2020

Purpose: The purpose of this research was to explore the impact of Jin Shin Jyutsu (JSJ) Self-Help on personal stress and the caring efficacy of nurses. Design: A randomized, controlled comparison study, with crossover design was conducted. Method: Stress and caring efficacy were measured via surveys at baseline, posteducation, and again 30 to 40 days after completion of the JSJ educational intervention. Self-reported stress was the primary endpoint as measured with the validated Personal and Organizational Quality Assessment–Revised 4 Scale (POQA-R4) survey. Caring Efficacy was measured using the Coates Caring Efficacy Scale. Findings: A total of 41 nurses consented and completed the study; 18 were in the education group and 23 were in the control group. Changes in stress were sustained in the education group for the POQA-R4. Changes observed in the control group were not sustained. Statistical differences were observed when comparing education and control from baseline to final surveys for measures of emotional vitality and buoyancy. Increases in nursing caring efficacy were observed in both groups. Scores were consistently higher in the education group. Statistically significant differences were observed from baseline to final measure for the education group. Conclusions: Results show JSJ as a viable option for stress reduction in nurses.

Published: July 2020

Objectives: To investigate trends in racial/ethnic differences in nursing home (NH) residents’ quality of life (QoL) and assess these patterns within and between facilities. Method: Data include resident-reported QoL surveys ( n = 60,093), the Minimum Data Set, and facility-level characteristics ( n = 376 facilities) for Minnesota. Hierarchical linear models were estimated to identify differences in QoL by resident race/ethnicity and facility racial/ethnic minority composition for 2011–2015. Results: White residents in low-proportion racial/ethnic minority facilities reported higher QoL than both minority and white residents in high-proportion minority facilities. While the year-to-year differences were not statistically significant, the point estimates for white–minority disparity widened over time. Discussion: Racial/ethnic differences in QoL are persistent and may be widening over time. The QoL disparity reported by minority residents and all residents in high-proportion minority facilities underscores the importance of examining NH structural characteristics and practices to ultimately achieve the goal of optimal, person-centered care in NHs.

Osteoporotic fracture is the main complication of osteoporosis (OP) and accounts for millions of injuries annually. Local intervention by intra-marrow injection has been a good option for preventing osteoporotic bone loss when the osteoporotic femoral fracture has been treated. In this study, tail vein transplantations were examined to evaluate the cell-based therapeutic approach for treating OP with adipose-derived stem cells (ADSCs) and platelet-rich fibrin releasates (PRFr) in an ovariectomized (OVX) mice model. Thirty-six 12-wk-old female ICR mice were randomly divided into six groups: untreated control; sham-operated; OVX-control; OVX-ADSCs; OVX-PRFr; and OVX-ADSCs+PRFr. Starting 8 wk after ovariectomy, the OVX mice received tail vein injections once each week for four consecutive weeks, then were evaluated radiographically and histopathologically 8 wk after the first injection. We also assessed changes to bone trabeculae in the proximal tibial growth plate. In OVX mice treated with ADSCs or PRFr alone, or with a combination of ADSCs and PRFr, the trabecular bone mineral density (BMD), bone volume ratios (BV/TV), and numbers (Tb.N) in the proximal tibia areas were significantly higher than that in the OVX-control group. Significant differences between OVX-treated mice and OVX controls were found for trabecular separation, but not for trabecular thickness. These results indicate that ADSCs or PRFr treatment enhances bone microarchitecture in OP. The treatment of bone loss of OVX mice with ADSCs+PRFr induced greater bone consolidation with bone tissue production ( P < 0.01) when compared to the others. Thus, we conclude that the transplantation of ADSCs combined with PRFr might provide an alternative strategy for the treatment of various bone disorders in OP with an unlimited source of cells and releasates.

Published: July 2020

Lumber species identification is an important issue for the wood industry. In this study, three types of neural networks (artificial neural network (ANN), deep neural network (DNN), and convolutional neural network (CNN)) were employed for classifying softwood lumber species using NIR spectroscopy. The results show that CNN, which is based on deep learning, was more stable than the other neural networks. In particular, the stability of the training process was remarkably improved in CNN models. During the training procedure, the validation accuracy of the CNN model was 99.3% for the raw spectra, 99.9% for the standard normal variate (SNV) spectra and 100.0% for the Savitzky-Golay second derivative spectra. Interestingly, there was little difference in the validation accuracies among the CNN models depending on mathematical preprocessing. The results showed that CNN is sufficiently adequate to classify the softwood lumber species.
Looking for European solutions. Trade unions in Central and Eastern Europe striving for cross-border solidarity
Authors: Czarzasty Jan , Adamczyk Sławomir , Surdykowska Barbara
Published: July 2020

This article deals with the dilemmas faced by trade unions from Central and Eastern Europe (CEE) in the context of their relations with western European (EU-15) unions and the European Trade Union Confederation (ETUC). The issue of cross-border solidarity is re-examined, taking into account its historical meanings as well as current developments under the pressures of globalisation and EU integration. The article analyses key factors affecting East–West trade union relations – different views within the ETUC, discontinuities in European social dialogue, challenges faced by European works councils and the uncertain future of transnational company agreements. Major dilemmas CEE unions cope with vis-à-vis their western counterparts are outlined. The question of how to achieve a common interest platform for trade unions from Central and Eastern Europe and from western Europe is raised, followed by a suggestion that ‘downward convergence’ in industrial relations is bringing the two regions closer.

Published: July 2020

A 6-mo-old female Chihuahua was presented with recurrent episodes of hypoglycemia and collapse. Physical examination revealed proportionate dwarfism, retained puppy hair coat, retained deciduous teeth, and open fontanelles. Routine blood tests revealed hypoglycemia, thrombocytosis, hypoproteinemia, and elevated alkaline phosphatase activity. The urinalysis, radiographs, and ultrasonographs were unremarkable. Endocrine testing revealed that insulin-like growth factor 1 was below the detection limit; concentrations of total thyroxine, baseline cortisol, and cortisol stimulated by tetracosactide acetate were within their reference intervals. The pituitary gland showed no organic abnormalities on magnetic resonance imaging. For definitive diagnosis, we conducted the stimulation test for growth hormone (GH) release and diagnosed isolated GH deficiency. Genetic investigation revealed that the present case had 4 point mutations in intronic regions and a 6-bp deletion in exon 5 of GH1. The bioinformatics tool PROVEAN algorithm predicted that the deletion in exon 5 could be deleterious to the function of GH1.
Mandated Choice Policies: When Are They Preferable?
Authors: Thaysen Jens Damgaard , Albertsen Andreas
Published: July 2020

Under mandated choice policies, people are free to choose whichever option they prefer, but “choosing not to choose” is penalized. In Australia, voting is mandatory, and abstaining is penalized with a fine. In New Zealand and several American states, it is mandatory for those who want to obtain a driver’s license that they decide whether to register as organ donors. If they fail to do so, they will not receive a driver’s license. Proponents of such policies stress that they may be the least autonomy-infringing ways of achieving some good and provide society with knowledge about people’s preferences and are, partly for these reasons, preferable to employing defaults. This article compares mandated choice in voting and donor registration with respect to the ends served, how a mandated choice policy will serve these ends, the distribution of burdens, and the nature of the possible options. It is argued that mandated choice is more attractive in the context of donor registration.

Published: July 2020

Background:

Hallux rigidus is a common arthritic condition that has been addressed surgically with a range of techniques, from an isolated cheilectomy to first metatarsophalangeal (MTP) joint fusion. Recently, hemiarthroplasty with polyvinyl alcohol (PVA) hydrogel implant has been used as an alternative treatment to relieve pain while preserving motion of the first MTP joint. We retrospectively reviewed patient-reported outcome scores and clinical outcomes for patients treated for hallux rigidus with PVA hydrogel implant at an academic, multisurgeon center.

Methods:

A total of 103 patients who underwent first MTP hemiarthroplasty with PVA hydrogel implant between January 2017 and October 2018 were retrospectively reviewed (average, 26.2 months). Eight surgeons were represented. Baseline Patient-Reported Outcomes Measurement Information System (PROMIS) scores for the Physical Function, Pain Interference, Pain Intensity, Global Physical Health, Global Mental Health, and Depression domains were collected prospectively and compared with PROMIS scores collected at a minimum of 1 year postoperatively (average, 13.9 months). Seventy-three patients had both preoperative and postoperative scores. Ten of these patients had undergone a prior procedure of the first MTP, and 52 underwent concurrent Moberg osteotomy at the time of PVA hydrogel implantation.

Results:

For patients with baseline and postoperative PROMIS scores, significant pre- to postoperative improvement was detected for the Physical Function, Pain Interference, Pain Intensity, and Global Physical Health domains ( P < .05). Patients who had undergone a prior procedure of the first MTP had significantly higher postoperative Pain Intensity scores compared with those who did not undergo a prior procedure. Patients undergoing concurrent Moberg osteotomy had significantly lower postoperative Pain Interference and Pain Intensity scores compared with those who did not undergo a Moberg. Two patients underwent revision procedures in the first 2 years postoperatively, one with revision hemiarthroplasty and one with conversion to arthrodesis.

Conclusion:

On average across our entire cohort, physical function and pain scores improved significantly pre- to postoperatively; however, postoperative pain scores were significantly higher for patients who had undergone a prior procedure of the first MTP and significantly lower for patients who underwent concurrent Moberg osteotomy. The implant displayed excellent survivorship in the first 2 years postoperatively, with only 2 revision procedures.

Coordination and vibration control for two sets of flexible satellites with input constraints and actuator failures
Authors: Ji Ning , Yang Hongjun , Liu Jinkun
Published: July 2020

In this study, we considered the coordination and vibration control for two sets of flexible satellite systems with input constraints and actuator failures. The parameters of both systems were kept uniform, and one was called the master flexible satellite, and the other one was called slave flexible satellite. The two sets of the flexible satellite systems were modelled as partial differential equations. Coordination control laws were designed to turn the master flexible satellite system to the desired angle and then turn the slave system to the angle of the master satellite system. Furthermore, the hyperbolic tangent function was adopted to realize the control input constraint. The adaptive control laws were designed to ensure that the systems work normally even when the actuator fails. Lyapunov’s direct method was adopted and stability analysis was given. Finally, numerical simulations were conducted to validate the results.
Advanced Practice Registered Nurses Using Synchronous Telepsychiatry: An Integrative Systematic Review
Authors: Finley Brooke A. , Shea Kimberly D. , Maixner Roberta , Slebodnik Maribeth
Published: July 2020

BACKGROUND: Despite wide-spread use, telepsychiatry use among psychiatric mental health advanced practice nurse practitioners (PMH APRNs) has not been systematically explored in the literature. AIMS: Systematically review the PMH APRN usage of live-time, synchronous telepsychiatry including audiovisual teleconferencing technology. METHOD: A comprehensive, systematic search was performed with no publication date restriction across CINAHL, the Cochrane Library, Embase, Google Scholar, PsycINFO, PubMed, Scopus, and Web of Science on July 30, 2019, by a medical librarian. Each citation was blinded and independently reviewed by three reviewers, and consensus was reached for inclusion. Eligible articles were peer-reviewed research or quality improvement articles available in full-text, written in English, including real-time, synchronous, audiovisual telepsychiatry services with PMH APRN providers. Discussion articles and literature reviews were excluded. Article quality and bias were assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment tool. RESULTS: The search yielded a total of 342 articles, and only nine articles met full inclusion criteria. Overall, risk of bias was high in all studies, and the GRADE rating consisted of three “very low,” five “low,” and one “medium” quality article. However, considering the collectively positive outcomes from PMH APRN telepsychiatry use, the overall GRADE recommendation was to “probably do it” for seven studies and “do it” for two studies. CONCLUSIONS: Though existent literature is low quality and sparse, evidence supports that PMH APRNs can feasibly and successfully provide telepsychiatry services across a wide range of demographic patients and locations. PMH APRNs should contribute more original evidence to guide telepsychiatry implementation and adoption as the service expands.

How feminists pick porn: Troubling the link between ‘authenticity’ and production ethics
Authors: Macleod PJ
Published: July 2020

This article presents findings from an empirical study into the experiences of feminists who use pornography, with a focus on how feminists choose the material with which they engage. It discusses the ways in which participating feminists understood notions of authenticity in relation to porn, as well as the role played by perceptions of ‘authentic representation’ in their porn selection processes and ethical decision-making. The article problematizes the link made by interviewees between more authentic-seeming representations of sex, bodies and pleasure on one hand, and superior production standards and/or more enthusiastic performer consent on the other. It furthermore argues that uncritical demands for authenticity in porn risk undermining broader ‘sex positive’ or ‘anti-anti-porn’ feminist political goals, particularly around stigma reduction and the elimination of exploitative industry practices. In this way the article offers a meaningful contribution to academics, activists and others engaged in the discussion around porn consumption ethics and the ethics of porn consumption, as well as those working on ways to address exploitation within the pornography industries.
Why settle when there are plenty of fish in the sea? Rusbult’s investment model applied to online dating
Authors: Sharabi Liesel L , Timmermans Elisabeth
Published: July 2020

The current mixed-methods study reports the results of a cross-sectional survey of 205 online daters and uses the Investment Model to examine the antecedents of commitment in online dating and users’ decisions to delete their online dating account(s). We hypothesized that the quality of alternatives, investments, and satisfaction with the online dating relationship would mediate the association between online dating intensity and commitment, which, in turn, would predict the intention to terminate an account. The analyses revealed that online dating intensity was associated with greater commitment and a lower likelihood of account termination. There were also specific indirect effects on commitment through the quality of alternatives, investments, and satisfaction, and on termination through investments. Responses to an open-ended question provided more information about users’ decisions to quit online dating. These results point to ways online dating may facilitate the desire for commitment while potentially undermining the long-term stability of relationships.
Belief without evidence? A policy research note on Universal Design for Learning
Authors: Murphy Michael PA
Published: July 2020

Developed first in the late 1990s by the Centre for Applied Special Technology, the pedagogical framework known as “Universal Design for Learning” (UDL) has drawn increasing investment from K-12 and post-secondary institutions. The promoters of UDL often frame the approach as being “based in neuroscience,” and further as an “evidence-based approach” to instructional design in teaching and learning. While the rhetoric is promising, no rigorous published research has demonstrated any improvement in an education intervention designed with UDL principles in mind. Furthermore, the community of practice around UDL appears to be hostile to questions around the rigor of analysis used to promote UDL interventions. Studies of UDL approaches do not follow best practices in terms of research design, and often solicit anecdotes rather than testing the effectiveness of the approach. The purpose of this policy research note is to survey the state of the art in researching UDL and to clarify the origin of the pedagogical theory. Because the effectiveness of this theory has not been proven, there are no grounds for UDL implementation plans to be framed as “evidence-based” decisions. Further, the reluctance of UDL advocates to rigorously study the effectiveness of their intervention raises important questions about their confidence in the theory. For these reasons, the only evidence-based conclusion that can be made about UDL is that further study is required, as its core claims remain unproven. Institutions of any educational level should proceed with caution before devoting significant resources to implementation of UDL.
Development of helical auxetic yarn with negative Poisson’s ratio by combinations of different materials and wrapping angle

Published: July 2020

Auxetic materials have negative Poisson ratio which has a multiple ranges of functional applications. The helical auxetic yarn was successfully developed through direct twist system by using core and wrap yarn or filament, which shows Auxeticity when the HAY is stretched in longitudinal direction in response it expand in transverse direction, Helical Auxetic Yarns were developed using various parameters of the core and warp filament, these parameters are wrapping angle (Twist per meter), diameter ratio, and modulus ratio. The strength of Helical yarn was characterized using single yarn strength and Image J software was used for the calculation of poisson’s ratio. According to test results, it is concluded that the core filament of helical auxetic yarn increased its thickness in transverse direction under stress, and a considerable negative poisson’s ratio was calculated. The values of negative poisson’s ratio described that the auxeticity had a direct relation with core filament thickness or diameter and inversely proportional to the linear density of wrap filament, in case of the wrap angle the auxeticity of HAY yarn had an inverse effect with wrap angle. Kevlar/polypropylene combination sample showed maximum auxeticity at a 15-degree angle while Kevlar/nylon combination sample showed minimum auxeticity at a 25-degree wrap angle.
Exploratory Review: Self-Report IADL Assessments in the age of Internet-Connected Assistive Devices

Published: July 2020

Internet-Connected Assistive Devices (iCAD), like accessible smartphones, tablets, computers, and apps, have become an integral part of everyday functioning for people with disabilities (PWD). The objective of this article was to identify self-report assessments having the relevance and clinical applicability for assessing satisfaction with performing Instrumental Activities of Daily Living (IADL) for PWD using iCAD. An exploratory review was conducted to identify self-report assessments that were appropriate, practical, clinically fit, and psychometrically acceptable, for assessing satisfaction with performing IADLs for PWD using iCAD. Thirty-two IADL assessments were identified, of which six met inclusion criteria. Four of six assessments did not specifically address iCAD usage, while two assessments had limited relevance and clinical applicability, for assessing satisfaction with performing IADLs for PWD using iCAD. This review establishes the growing need for a self-report IADL assessment that has been specifically designed and validated for assessing satisfaction with performing IADLs for PWD using iCAD
The Importance of Leverage in GlaxoSmithKline’s China Engagement: A Revelatory Case Study
Authors: Thorley Martin , Fulda Andreas
Published: July 2020

This article critically examines multinational corporation (MNC)–host government relations in the People’s Republic of China (PRC) through the prism of the GlaxoSmithKline (GSK) corruption scandal. The article takes the episode as a revelatory case study and analyses it with a view to uncovering further data on the imperatives that govern interactions between the PRC and MNCs. Drawing upon the theoretical framework provided by David M. Anderson’s conception of leverage, the authors attempt to unite the two themes of cultural analysis and commercial analysis. By highlighting both the rising commercial risks for MNCs and considerable legal risks for Chinese and non-Chinese intermediaries working on their behalf, the case itself underlines a gulf between theoretical understanding and practical experience of engagement with China in this sphere. The authors argue that the GSK corruption case demonstrates both that MNC normative bargaining leverage (the use of standards and norms, considered legitimate by both sides, to gain advantage or protect one’s position) in the PRC is illusory and that the Chinese party-state possesses far greater negative bargaining leverage (leverage based upon the capacity to make the other side worse off) than typically assumed.
Aesthetic Preference and Time: Preferred Painting Dilates Time Perception
Authors: Li Lingjing , Tian Yu
Published: July 2020

In the domain of aesthetic preference, previous studies focused primarily on exploring the factors that influence aesthetic preference while neglecting to investigate whether aesthetic preference affects other psychological activities. This study sought to expand our understanding of time perception by examining whether aesthetic preference in viewing paintings influenced its perceived duration. Participants who preferred Chinese paintings ( n = 20) and participants who preferred western paintings ( n = 21) were recruited to complete a temporal reproduction task that measured their time perception of Chinese paintings and of western paintings. The results showed that participants who preferred Chinese paintings exhibited longer time perceptions for Chinese paintings than for western paintings, while the participants who preferred western paintings exhibited longer time perceptions for western paintings than for Chinese paintings. These results suggested that aesthetic preference could modulate our perceived duration of painting presentation. Specifically, individuals perceive longer painting presentation durations when exposed to the stimuli matching their aesthetic preferences.

The triad of diarrhea, dementia, and dermatitis constitutes the clinical diagnosis of pellagra. However, most reported cases of pellagra have occurred without all components of the triad. Pellagra was declared eradicated in the United States after an outbreak in the 1920s, and is now considered to be an exceedingly rare diagnosis in developed countries. In this article, we present a case of a 56-year-old man who presented with a significant history of alcohol use and chronic diarrhea. Pellagra was clinically diagnosed based on the triad of diarrhea, cognitive dysfunction, and dermatitis in this malnourished, alcoholic patient. The patient was treated and clinically improved with resolution of his diarrhea and cognitive dysfunction.
Transition to HE and Equitable Learning Outcomes: Challenges for Indian Higher Education
Authors: Navani Manasi Thapliyal
Published: July 2020

Indian higher education (HE) system has undergone rapid expansion over the last two decades, emerging as one of the largest HE systems in the world. Expansion is accompanied by the challenge of ensuring comparable quality education across a diverse institutional spectrum. Simultaneously, academic reforms in the sphere of general HE have been pursued in recent years to align HE with global quality assurance frameworks. This creates an intrinsic pull in the system where international benchmarks juxtapose against demands made on HE institutions (HEIs) to meet the needs of and support first-generation learners coming from disadvantaged backgrounds to enable them to transition successfully to academic cultures of colleges. This article addresses the challenge for equity and institutional challenge to find ways to engender the pedagogical and scaffolding processes accountable to the ‘educational outcomes’ through ensuring attainment of specified graduate attributes.
