From Bread and Roses to #MeToo: Multiplicity, Distance, and the Changing Dynamics of Conflict in IR Theory
Authors: Riordan Christine A. , Kowalski Alexander M.
Published: November 2020

A central assumption in industrial relations theory is that conflict is rooted in an enduring difference between the interests of labor and management. In recent years, the reality of work has changed for many, and scholarship has called attention to overlooked dimensions of conflict that depart from this assumption. The authors account for these developments with the concepts of multiplicity and distance. Multiplicity means that a broad range of actors bring diverse goals, tied to identities and values in addition to interests, to the employment relationship. The competing and fluid motivations that stem from these goals alter how actors individually and collectively name conflict. Distance reflects a growing rift between those who control work and those who labor, rooted in prevailing organizational forms and practices and the transformation of institutions. Distance alters actors’ interdependence and their perceived and actual power in addressing conflict. From these observations, the authors derive propositions suggesting directions for research and theory regarding conflict and the institutions through which actors balance goals.
Drivers of service delivery modes in Dutch local government: an analysis over time and across domains
Authors: Schoute Martijn , Gradus Raymond , Budding Tjerk
Published: November 2020

This study investigates the influence of service, financial and political characteristics on municipalities’ choices of four service delivery modes in the Dutch local government setting, thereby making a distinction between services in the physical and in the operational domain. It shows that, overall, use of inter-municipal cooperation and, to a lesser extent, municipality-owned firms increased substantially from 2010 to 2018. For use of private firms, we find remarkable differences. Whereas this use increased for the physical domain, it decreased for the operational domain. For both domains, we find that in-house production decreased substantially. We also find that the influence of especially transaction cost characteristics on the likelihood that municipalities choose a certain institutional form differs between 2010 and 2018, as well as between the physical and the operational domain.

Points for practitioners

Our finding that the use of in-house production decreased substantially from 2010 to 2018 suggests that municipalities are looking for mixed institutional forms, such as inter-municipal cooperation, to realize economies of scale. We observe that service delivery modes are especially driven by service characteristics, thereby stressing the importance of transaction cost motives in decisions about service delivery modes. However, our study also shows that financial and political characteristics have some influence. As the effects of the latter are not stable, we show that the way to implement reforms may vary over time and across domains.

Authors: Pitchika V. , Jordan R. , Micheelis W. , Welk A. , Kocher T. , Holtfreter B.
Published: November 2020

The long-term effectiveness of powered toothbrushes (PTBs) and interdental cleaning aids (IDAs) on a population level is unproven. We evaluated to what extent changes in PTB and IDA use may explain changes in periodontitis, caries, and tooth loss over the course of 17 y using data for adults (35 to 44 y) and seniors (65 to 74 y) from 3 independent cross-sectional surveys of the German Oral Health Studies (DMS). Oaxaca decomposition analyses assessed to what extent changes in mean probing depth (PD), number of caries-free surfaces, and number of teeth between 1) DMS III and DMS V and 2) DMS IV and DMS V could be explained by changes in PTB and IDA use. Between DMS III and V, PTB (adults: 33.5%; seniors: 28.5%) and IDA use (adults: 32.5%; seniors: 41.4%) increased along with an increase in mean PD, number of caries-free surfaces, and number of teeth. Among adults, IDA use contributed toward increased number of teeth between DMS III and V as well as DMS IV and V. In general, the estimates for adults were of lower magnitude. Among seniors between DMS III and V, PTB and IDA use explained a significant amount of explained change in the number of caries-free surfaces (1.72 and 5.80 out of 8.44, respectively) and the number of teeth (0.49 and 1.25 out of 2.19, respectively). Between DMS IV and V, PTB and IDA use contributed most of the explained change in caries-free surfaces (0.85 and 1.61 out of 2.72, respectively) and the number of teeth (0.25 and 0.46 out of 0.94, respectively) among seniors. In contrast to reported results from short-term clinical studies, in the long run, both PTB and IDA use contributed to increased number of caries-free healthy surfaces and teeth in both adults and seniors.
Constraining Ideas: How Seeing Ideas of Others Harms Creativity in Open Innovation
Authors: Hofstetter Reto , Dahl Darren W. , Aryobsei Suleiman , Herrmann Andreas
Published: November 2020

Open innovation contests that display all submitted ideas to participants are a popular way for firms to generate ideas. In such contest-based ideation, the authors show that seeing numerous competitive ideas of others harms, rather than stimulates, creative performance (Study 1). Others’ competitive prior ideas interfere with idea generation, as new ideas need to be differentiated from the preceding ones to be original. Exposure to an increasing number of prior ideas thus heightens individuals’ perceived constraints of expressing ideas and harms creative performance (Studies 2 and 3). Furthermore, creative performance monotonically reduces with an increasing number of prior ideas (Study 4). A final study demonstrates that showing only a limited number of ideas as well as grouping prior ideas offer actionable ways to reduce prior ideas’ harmful influence (Study 5). These results illustrate viable ways to improve contest-based ideation outcomes merely by changing how competitive prior ideas are presented.
Who Are the People? Defining the Demos in the Measurement of Democracy
Authors: Koenig-Archibugi Mathias
Published: November 2020

Large-scale efforts to measure the democratic nature of polities across space and time are most useful when they reflect the variety of conceptions of democracy developed by political theorists. Traditionally, the attention of political theorists as well as political scientists focused on what it means for the people to rule, to the neglect of the equally important question of who the relevant people should be. In recent years, however, an increasing number of political theorists have tackled the problem of defining the demos and offered a wide range of answers. The article argues that empirical democracy measurement projects should take into account the variety of conceptions of the demos debated today instead of assuming consensus on this dimension. It also discusses how this can be done systematically. The arguments are developed with reference to the most ambitious and comprehensive democracy measurement project yet: Varieties of Democracy (V-Dem).
Factor Structure and Measurement Invariance of the Irrational Beliefs Inventory for University Students in the United States and Iceland
Authors: Heimisson Gudmundur T. , Dedrick Robert F.
Published: November 2020

We used multigroup confirmatory factor analysis to evaluate the five-factor measurement model underlying the 50-item Irrational Beliefs Inventory (IBI) in samples of university students in the United States ( n=827) and Iceland ( n=720). Global model fit was marginally acceptable in each sample. Further analyses identified several sources of model misfit that included weak factor loadings, several item pairs with correlated errors, and items with loadings on more than one factor. Cronbach’s alpha reliability estimates for the five factors were similar for the U.S. and Icelandic samples, and comparable to those reported by the developers of the IBI. Measurement invariance testing supported configural (same form) and metric invariance (equal loadings), but identified only 20 items that had invariant item intercepts across the U.S. and Icelandic groups. Given the finding of partial measurement invariance, we offer caution when using the IBI to make group comparisons for U.S. and Icelandic samples. Recommendations are proposed for ongoing psychometric evaluations of the IBI that would identify strengths of the IBI and items that, if revised or deleted, may improve the quality of the measure for research and clinical purposes.

Published: November 2020

Objectives

Built environments can affect health, but data in many geographic areas are limited. We used a big data source to create national indicators of neighborhood quality and assess their associations with health.

Methods

We leveraged computer vision and Google Street View images accessed from December 15, 2017, through July 17, 2018, to detect features of the built environment (presence of a crosswalk, non–single-family home, single-lane roads, and visible utility wires) for 2916 US counties. We used multivariate linear regression models to determine associations between features of the built environment and county-level health outcomes (prevalence of adult obesity, prevalence of diabetes, physical inactivity, frequent physical and mental distress, poor or fair self-rated health, and premature death [in years of potential life lost]).

Results

Compared with counties with the least number of crosswalks, counties with the most crosswalks were associated with decreases of 1.3%, 2.7%, and 1.3% of adult obesity, physical inactivity, and fair or poor self-rated health, respectively, and 477 fewer years of potential life lost before age 75 (per 100 000 population). The presence of non–single-family homes was associated with lower levels of all health outcomes except for premature death. The presence of single-lane roads was associated with an increase in physical inactivity, frequent physical distress, and fair or poor self-rated health. Visible utility wires were associated with increases in adult obesity, diabetes, physical and mental distress, and fair or poor self-rated health.

Conclusions

The use of computer vision and big data image sources makes possible national studies of the built environment’s effects on health, producing data and results that may inform national and local decision-making.
Amino-modified Reactive Red 195/P(styrene-co-butyl acrylate-co-trimethyl(vinylbenzyl) ammonium chloride) nanospheres with high coloration performance for enhancing cotton dyeability
Authors: Wang Dongwei , Fang Kuanjun , Liu Xiuming , Zhang Xinqing
Published: November 2020

Reactive dye is widely used for cotton dyeing, but its low utilization results in vast amounts of colored effluent with high salinity discharge. Amino-modified Reactive Red 195/P(styrene-co-butyl acrylate-co-trimethyl(vinylbenzyl) ammonium chloride) nanospheres (Am-RPNs) are a kind of novel colorant that exhibit excellent dyeing ability for cotton fabrics and higher dye utilization than original reactive dyes. The colored polymer nanospheres demonstrated small size, high stability and dye content in the dispersion system when cationic polymer nanospheres were dyed at an optimal dye dosage of 100%. Transmission electron microscopy images showed that the polymer nanospheres have smooth spherical shapes. Am-RPNs with an average hydration diameter of 96.5 nm and zeta potential of −33.7 mV were fabricated after being modified with ethylenediamine at pH 11. Both analytical techniques, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy, indicated the presence of –NH2 on the surface of Am-RPNs. The amino-modification mechanism of the Reactive Red 195/P(styrene-co-butyl acrylate-co-trimethyl(vinylbenzyl) ammonium chloride) nanospheres depended on the dyeing bath pH. The color depths of the cotton fabrics dyed with Am-RPNs reached up to 3.1 times higher than those with Reactive Red 195. Scanning electron microscopy images showed that Am-RPNs form stable deposits on the surface of the modified fibers. The cotton fabrics dyed with Am-RPNs possessed excellent rubbing and washing fastness, satisfactory light fastness, and desirable handle. This study provides an innovative method that employ Am-RPNs with high coloration performance to endow the cotton fabric with deep color and good colorfastness without using inorganic salt.
Role of Narrow Band Imaging Endoscopy in Preoperative Evaluation of Laryngeal Leukoplakia: A Review of the Literature
Authors: Campo Flaminia , Ralli Massimo , Di Stadio Arianna , Greco Antonio , Pellini Raul , de Vincentiis Marco
Published: November 2020

Introduction:

Leukoplakia is a precancerous lesion considered to be within the spectrum of histopathological results from parakeratosis, through stages of dysplasia to invasive cancer. Narrow band imaging (NBI) endoscopy has been introduced to improve early diagnosis of benign and malignant laryngeal lesions. The aim of this literature review was to evaluate the accuracy of preoperative evaluation of vocal fold leukoplakia with NBI endoscopy in comparison with histology.

Methods:

A systematic review of the literature was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using 3 different databases: PubMed, Embase, and Scopus. The included articles in the systematic review were identified combining each of the following terms: “narrow band imaging” OR “NBI,” [AND] with each of these terms: “laryngeal leukoplakia,” OR “vocal fold leukoplakia,” OR “vocal cord leukoplakia.”

Results:

The articles that fully met the inclusion criteria were 5 case series, conducted between January 2010 and February 2018, and published between 2017 and 2019. The selected articles included 312 patients (86% males and 14% females), affected by 382 vocal cord leukoplakia, evaluated with NBI endoscopy and that underwent surgical microlaryngoscopy with biopsy. Based on the studies included in the review, accuracy of NBI in predicting malignancy within leukoplakia ranged from 81% to 97.8%, demonstrating to be an accurate method to predict the risk of malignant transformation of vocal fold leukoplakia.

Conclusion:

Narrow band imaging can help otolaryngologists in the decision-making process on the necessity to perform a biopsy and transoral surgery or long-term follow-up. Larger studies are necessary to confirm the high association of NBI evaluation of the epithelium surrounding the leukoplakia with the histological diagnosis.

Authors: Hung Chuan-Jen , Liu Yu-Hsi , Liao Jia-Bin
Published: November 2020

Oncocytic tumors comprise a group of rare benign neoplasm of salivary glands, accounting for less than 1% of all salivary gland tumors. Nodular oncocytic hyperplasia characterized by multiple unencapsulated oncocytic nodules in the salivary glands is an extremely rare condition. We report a case of bilateral nodular oncocytic hyperplasia of parotid glands with parapharyngeal space extension in an 80-year-old woman whose initial presentation was recurrent parotitis. Our case may be the first report of nodular oncocytic hyperplasia in the parapharyngeal space, arising from the parotid gland. The patient underwent total parotidectomy and excision of parapharyngeal tumors using a transparotid transcervical approach, and at the 2-year follow-up, no evidence of recurrence was found.
Primary Heterotopic Meningioma of Nasal Cavity: Case Report and Literature Review
Authors: Hu Xianwen , Jiang Maoyan , Feng Zelong , Wang Juan , Wang Pan , Cai Jiong
Published: November 2020

Primary heterotopic meningiomas are lesions that are not associated with a cranial nerve foramen, vertebral canal, or intracranial structure. The most common histopathological subtype is meningeal epithelioma. In clinical practice, primary heterotopic nasal meningioma occurs relatively rarely, and its most common pathological type is psammomatous meningioma, whereas nasal fibrous meningioma is infrequent. In our case, a 31-year-old male patient was admitted to the hospital with “progressive nasal obstruction on the right side for half a year.” Computed tomography examination of the paranasal sinuses revealed a polyploid mass in the right nasal cavity. The patient underwent surgical resection of the mass under nasal endoscopy. Histopathological examination confirmed that the mass was an ectopic meningioma of the nasal cavity. The patient was regularly followed up for 2 years without recurrence of the tumor. Primary heterotopic fibrous meningioma of the nasal cavity is clinically rare but should be considered as a differential diagnosis for hemangioma of the nasal cavity, inverted papilloma, and nasal polyp. The final diagnosis is based on pathology and immunohistochemistry analysis results.
Magnitude and Risk Factors for Interpersonal Violence Experienced by Canadian Teenagers in the Sport Context
Authors: Parent Sylvie , Vaillancourt-Morel Marie-Pier
Published: November 2020

Recent studies demonstrate that interpersonal violence toward athletes (VTA) is a significant problem in some countries. However, in Canada, little scientific evidence on the prevalence of this issue exists. The objective of this study was to describe the magnitude of interpersonal violence toward young Canadian athletes in the context of sport and to explore associated risk factors. A total of 1,055 athletes, aged between 14 and 17 years, anonymously completed an online survey about their experiences of various types of interpersonal violence in sport. The sample consisted of 763 girls and 292 boys, with a mean age of 15.3 ± 1.1 years. Results showed that 79.2% of athletes reported at least one experience of psychological violence followed by 39.9% reporting physical violence, 35.7% reporting neglect, and 28.2% sexual violence. Being older, being a girl, having specialized in a sport early on, and a high number of hours of weekly practice were related to higher odds of reporting psychological violence or neglect. Being older, being a boy, reporting a nonheterosexual sexual preference, greater number of hours of weekly practice, being in an interregional or provincial sport level, and practicing only team sports were related to higher odds of reporting physical violence. Reporting a nonheterosexual sexual preference and being in an interregional or international sport level were associated with higher odds of reporting sexual violence. In conclusion, this study shows that VTA, particularly psychological violence and neglect, is a serious problem in youth sport in Canada. These results may help to influence public decision makers to intervene and develop and implement strategies to prevent VTA.
Compound heterozygosity for hemoglobin variant Hb-Broomhill and the Southeast Asian α-thalassemia deletion does not worsen outcome: a case report of two unrelated patients
Authors: Qin Danqing , Du Li , Wang Jicheng , Yao Cuize , Guo Hao , Yuan Tenglong , Liang Jie , Yin Aihua
Published: November 2020

We report two unrelated cases of compound heterozygosity for hemoglobin (Hb) variant Broomhill and the Southeast Asian (- - SEA/) α-thalassemia deletion, whose clinical features and laboratory findings have never been reported. Hematological analyses revealed abnormal values for both cases as α-thalassemia traits, and capillary electrophoresis suggested an abnormal peak that was incompletely separated from the Hb A peak. A suspension array system and Sanger sequencing were used to characterize the genotypes. Sanger sequencing confirmed the presence of Hb Broomhill [α114(GH2)Pro→Ala; HBA1: c.343C>G]. Eventually, both cases were accurately diagnosed as compound heterozygotes for Hb Broomhill and the (- - SEA/) α-thalassemia deletion, which is the first known report of these variants. This information will be useful when providing appropriate genetic counselling and prenatal diagnosis.
Drainage smell and peritonitis are efficient indicators of anastomotic leakage after laparoscopic rectal cancer resection
Authors: Shiwakoti Enesh , Song Jianning , Li Jun , Wu Shanshan , Zhang Zhongtao
Published: November 2020

Objective

Anastomotic leakage (AL) is a frequent complication after laparoscopic rectal cancer resection (LRCR). The main objective of the present study was to identify accurate indicators of AL after LRCR.

Methods

A retrospective case-control study was performed of 185 patients who underwent laparoscopic surgery for rectal cancer between March 2012 and February 2017 at Beijing Friendship Hospital. Potential indicators of AL were examined via univariate and multivariate analyses. The performance of multivariate analysis was evaluated using receiver operating characteristic (ROC) curves.

Results

The overall AL rate was 17.84%. Multivariate analysis identified drainage smell (odds ratio [OR = 35.318, 95% confidence interval [CI] = 7.114 to 175.338) and peritonitis [OR = 17.475, 95% CI = 1.540 to 198.318) as independent indicators of AL. The area under the ROC curve was 0.720 (95% CI = 0.606 to 0.835).

Conclusion

Drainage smell and peritonitis could be reliable and accurate indicators of AL after LRCR.
Pathogenesis of traumatic temporomandibular joint ankylosis: a narrative review
Authors: He Linhai , Zhang Zhiyong , Xiao E , He Yang , Zhang Yi
Published: November 2020

Objective

To comprehensively review the literature and summarize the results from human and animal studies related to the possible causes and pathogenesis of traumatic temporomandibular joint ankylosis (TMJA).

Materials and Methods

The Google Scholar, Embase, and Web of Science databases were used to search for articles related to traumatic TMJA from 2011 to 2020. All articles were screened according to the inclusion and exclusion criteria, collected, and analyzed.

Results

Nineteen relevant articles were collected. These articles were classified into three groups: predisposing and etiological factors, cellular studies, and molecular studies.

Conclusion

The pathological mechanisms are similar between TMJA and nonunion hypertrophy. Aberrant structural and etiological factors as well as disordered cellular and molecular mechanisms might contribute to TMJA formation. Although preclinical and clinical data have provided new evidence on the pathogenesis of traumatic TMJA, the molecular mechanisms and biological events require further exploration.
Simultaneous determination of calycosin, prim-O-glucosylcimifugin, and paeoniflorin in rat plasma by HPLC-MS/MS: application in the pharmacokinetic analysis of HQCF
Authors: Gu Yulong , Piao Xianglan , Zhu Dan
Published: November 2020

Objective

This study aimed to develop and validate a high-performance liquid chromatography–tandem mass spectrometry method to simultaneously determine three bioactive components of the Huangqi Chifeng decoction (HQCF) in rat plasma.

Methods

Taxol was used as an internal standard in the developed method. Chromatographic separation was performed on a C18 column using a gradient elution with 0.1% formic acid in acetonitrile (v/v) and 0.1% formic acid in water (v/v) as the mobile phases at a flow rate of 0.4 mL·minute−1. All compounds were monitored via selected reaction monitoring with an electrospray ionization source.

Results

The lower limits of quantification of paeoniflorin, calycosin, and prim- O-glucosylcimifugin were 15.0, 0.75, and 0.75 ng·mL−1, respectively. The calibration curves indicated optimal linearity ( r > 0.99) across the concentration ranges. The specificity, precision, accuracy, recovery, matrix effect, and stability of the method were validated. This method was successfully applied in a pharmacokinetics study of the three compounds in rat plasma.

Conclusion

The pharmacokinetics results provide insights into the mechanisms of HQCF in vivo and its future clinical application.
Scapular Dyskinesis Is Not an Isolated Risk Factor for Shoulder Injury in Athletes: A Systematic Review and Meta-analysis
Authors: Hogan Campbell , Corbett Jo-Anne , Ashton Simon , Perraton Luke , Frame Rachel , Dakic Jodie
Published: November 2020

Background:

Scapular dyskinesis has been considered a risk factor for athletic shoulder injury; however, findings in the prospective literature have demonstrated mixed results.

Purpose:

To determine if scapular dyskinesis increases the risk of shoulder injury in athletes.

Study Design:

Meta-analysis.

Methods:

A systematic search was conducted on the MEDLINE, CINAHL Plus, SPORTDiscus, and Embase databases to identify prospective studies examining scapular dyskinesis and shoulder injury risk in athletes. Studies were included if they assessed participants using a dynamic scapular assessment at baseline and monitored for the development of shoulder injury. Data from the studies were subject to meta-analysis using the Mantel-Haenszel method to produce a pooled risk ratio.

Results:

Seven studies were eligible for inclusion, resulting in 212 shoulder injuries observed across 923 athletes. Scapular dyskinesis was present in 46% of participants, and these athletes had an injury rate of 25%. The presence of scapular dyskinesis displayed a trend to increase the risk of shoulder injury, but this was not statistically significant (risk ratio, 1.07; 95% CI, 0.85-1.34; P = .59).

Conclusion:

Scapular dyskinesis was not significantly associated with the development of shoulder injury in athletes.

Finding a proper “Mate”: Comparison of left ventricular assist devices using cerebral oximetry
Authors: Montgomery Morgan L , Stannard Blaine , Dzedzik Siarhei , Lin Hung-Mo , Anyanwu Anelechi , Levin Matthew A , Trinh Muoi
Published: November 2020

Introduction:

Axial-flow and centrifugal-flow left ventricular assist devices (LVAD) have been utilized in the management of heart failure, but it remains unknown whether these devices differ in end-organ perfusion. Our goal was to evaluate the association between device type and regional cerebral oxygen saturation (rSO2), and determine if this confers any benefit in short-term postoperative outcomes.

Methods:

Adult patients who underwent primary LVAD implantation at our institution from 2014 to 2019 were retrospectively analyzed. Patients were stratified into axial-flow and centrifugal-flow groups. Intraoperative rSO2 readings were used to calculate the change in mean rSO2 from pre- to post-bypass. Multivariable modeling was performed to compare delta rSO2 between groups, and to analyze the association between LVAD type and postoperative outcomes.

Results:

There were 152 patients included, of which 76 had an axial-flow device and 76 had a centrifugal-flow device implanted. The rSO2 level increased from pre-bypass to post-bypass on average 3.5% (CI: 2.1 to 5.0) for the axial group compared to 0.1% (CI: −1.2 to 1.4) for the centrifugal group, which was a significant difference (β = −2.22, CI: −4.21 to −0.32, p = 0.022). Axial devices approached significance for lower odds of postoperative complications (OR: 0.35, CI: 0.11 to 1.06, p = 0.063), and were associated with significantly shorter ICU LOS (β = −0.36, CI: −0.60 to −0.11, p = 0.004).

Conclusion:

Axial devices resulted in a greater increase in rSO2 than centrifugal pumps after separation from CPB. Further investigation is warranted to evaluate the effect of LVAD selection on long-term end-organ perfusion and subsequent patient outcomes.
China’s Accession to the WTO and the Collapse That Never Was
Authors: Jefferies William
Published: November 2020

This article examines the application of neoclassical economics to the discussion of China’s transition to the market in the 1990s and its accession to the World Trade Organization (WTO) in 2001. It shows how this theory shaped, and misled, forecasts of the impact of that accession and of China’s subsequent economic performance. It discusses the debate between mini-bang and big-bang transition policies in the 1990s and shows the two sides shared far more in common than separated them. Both sides misestimated, in fact grossly underestimated, the dynamism of China’s economy. It shows how widely anticipated predictions of crisis and collapse with China’s WTO accession were the natural result of the assumptions of the neoclassical model. It suggests that a rival model of market transition based on Bukharin and Kuznets has much to offer.

“If You Love Me, You Must Do...” Parental Psychological Control and Cyberbullying Perpetration Among Chinese Adolescents
Authors: Geng Jingyu , Wang Xingchao , Wang Yuhui , Lei Li , Wang Pengcheng
Published: November 2020

Considering the prevalence of cyberbullying, the current study explores the factors associated with its perpetration. Using self-determination theory, the association of parental psychological control (PPC) with cyberbullying perpetration was examined. To explore this influencing mechanism further, psychological reactance (PRt) and materialism were examined as two mediators in this relationship. Moreover, according to the diathesis–stress model and cognitive model of resilience, psychological resilience (PRl) was examined as a moderator in the direct and indirect link between PPC and cyberbullying perpetration. To test our expectations, 804 adolescents ( M = 13.12, SD = 1.16) participated in the current study using a cross-sectional design and multiple questionnaires, namely, the Chinese version of the Parental Control Questionnaire, Revised Cyber Bullying Inventory, Hong Psychological Reactance Scale, Material Values Scale for Children, and Resilience Scale for Chinese Adolescents. Correlation analysis indicated that PPC, PRt, materialism, and cyberbullying perpetration were significantly and positively correlated, and were significantly and negatively related to PRl. Moderated mediation analysis revealed that PRt and materialism played multiple mediating roles in the relationship between PPC and cyberbullying perpetration. Multiple mediation analysis indicated that PRl weakened the direct associations of PPC, PRt, and materialism with cyberbullying perpetration, further alleviating the indirect and direct associations of PPC with cyberbullying perpetration, supporting the moderated mediation model. Specifically, adolescents high in PPC were more likely to have stronger PRt and materialistic values, which further triggered cyberbullying perpetration. PRl can protect adolescents high in PPC from cyberbullying perpetration via weakening the direct and indirect associations of PPC with cyberbullying.

Published: November 2020

Archaeological cultures are commonly defined by typologies established from ceramic assemblages at sites dated to a relatively restricted timeframe and located in specific geographic regions. It is often assumed that cultural traditions, social organizations, and other aspects of lifeways were similar throughout the established cultural areas. However, variations in pottery assemblages, burial practices, house construction techniques, and subsistence strategies are observed among late Neolithic Dawenkou culture sites in China. This study uses stable isotopic, archaeobotanical, and archaeozoological analysis to investigate variation in diet at middle and late Dawenkou sites. We provide new isotopic data for two sites and a comparison of results for all studies to date for the Dawenkou culture area. There is significant synchronic and diachronic variation, both among and within sites, during the middle and late Dawenkou period. There are multiple potential explanations for this variability including constraints from environmental factors such as temperature, precipitation, local geomorphology, and social factors such as gender, social status, and ethnicity. This study demonstrates that closer examination of Dawenkou culture sites using multiple approaches provides a more nuanced understanding of variation in communities that deserve further analysis.

Published: November 2020

The public concern for industrial pollution is urging for an economical solution to remove industrial effluent that increases the risk of human cancers. Currently, there are a few successful techniques implemented for dye removal; however, little has been done in the field of using reusable biological material extracted from waste. We propose a new procedure to fabricate biocompatible magnetic collagen for dye removal. Our study was conducted on crystal violet (CV) removal from industrial effluent using fish scales collagen. In this study, removal of dye by adsorption on various types of collagen was studied using soft, coarse and magnetic collagen nanocomposite. The magnetic collagen nanocomposite was synthesized by coprecipitation method followed by mixing of iron nanoparticles with collagen. Characterization of the prepared materials was performed using transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). Soft collagen, coarse collagen and magnetic collagen nanocomposite were proved to adsorb crystal violet dye at concentrations up to 1000 ppm. Uptake capacity was 92% at 100 ppm of CV while cytotoxicity was reduced to 15%. The ability of collagen and magnetic collagen nanocomposite to adsorb the dye and thus reducing the polluted water cytotoxicity, as well as accumulating under the action of the magnetic field was proved experimentally.
High-density polyethylene/asphaltene composites: Thermal, mechanical and morphological properties
Authors: Moradkhani Reza , Hosseini-Dastgerdi Zeinab , Sirousazar Mohammad
Published: November 2020

In this work, a series of high-density polyethylene (HDPE)/asphaltene composites were fabricated via the melt blending method. The composites were characterized, and the degradability, thermal, and mechanical stabilities of the products were analyzed. TGA results showed that HDPE/asphaltene composites had better thermal properties, e.g. higher degradation temperatures than asphaltene-free pristine HDPE. The high intermolecular interactions between the asphaltene and HDPE resulted in the degradation mechanism break, delaying the decomposition of composites and increasing their thermal stabilities. The results of DSC analysis indicated that the presence of asphaltene induces higher crystallinity and melting temperature in the composite matrix. According to the XRD results, the crystalline size was increased by increasing the asphaltene loading level due to the nucleating effect of asphaltene and the proper interactions developed between the asphaltene particles and HDPE chains. The proper dispersion of asphaltene in the composite matrix was confirmed by SEM images. The obtained results from the hardness analysis indicated higher mechanical stability for the composites, proportional to the content of the incorporated asphaltene to the composite. The results showed that asphaltene can be considered as an appropriate choice to improve the HDPE properties.

Aesthetic/affective norms around femininity could be an obstacle to women’s performance of exercise. Gender differences are significant: women are considerably more inactive than men. In this article we worked with the notion of body image and body affect, with the aim of reflecting on how aesthetic/affective norms around femininity could be an obstacle to women’s performance of exercise in Chile. To understand how these aesthetic/affective norms hinder physical activity, we analyzed media images using a qualitative methodology. The results show that there are four types of female body: extremely thin, thin, fat, and obese. This study explores how affectivity relates to the way in which exercise should be experienced: women must enjoy the actions in order to achieve the ideal body; indeed, they must experience them as pleasant. They should also be performed on a body that feels graceful, fragile, and small. We draw conclusions on the way in which images promote a body affect for the self and for others that becomes a barrier to the performance of female exercise.
After the celebration: Marriage equality in EU Law post-Coman in eight questions and some further thoughts

Published: November 2020

This paper provides a detailed critical analysis of the case of Coman, where the Court of Justice clarified that the meaning of the term ‘spouse’ in Directive 2004/38 was gender-neutral, opening up the door for same-sex marriage recognition for immigration purposes all around the EU, thus destroying the heteronormative misinterpretations of the clear language of the Directive practised in a handful of Member States. The state of EU law after Coman is still far from perfect, however: we underline a line of important questions which remain open and which the Court will need to turn to in the near future to ensure that marriage equality moves beyond mere proclamations in the whole territory of the Union.

We evaluated serologic responses of cattle, bison, elk, and swine representing negative control, early vaccination (4–8 wk), late vaccination (21–28 wk) or booster vaccination, early after-experimental challenge (2–4 wk), and late after-experimental challenge (8–21 wk), in a brucellosis fluorescence polarization assay (FPA; n = 10 sera per species per treatment) using negative control sera from cattle, bison, elk, and swine ( n = 5 per species). Sera from cattle shedding Brucella abortus strain RB51 in milk were also evaluated against the 20 negative control sera. The species of negative control sera used in the FPA could increase ( p < 0.05) delta millipolarization (mP; delta mP = sample mP − negative control mP) results. In general, the species of negative control sera did not alter the interpretation of FPA results in control, vaccinated, or infected animals. Even after repeated RB51 vaccinations in bison, cattle, or elk, or in cattle shedding RB51 in milk, serologic results from the FPA remained negative. Species differences in FPA results were noted; elk developed robust humoral responses very quickly after infection that resulted in strong positive FPA results. In cattle and bison, humoral responses appeared to develop over a longer period of time, and greater delta mP values were detected at later times after infection. Sensitivity of the FPA for detecting infected animals was greatest for elk in early challenge samples and bison in late challenge samples. Our data suggest that species of origin of negative control sera does not influence interpretation of the FPA in natural hosts of Brucella abortus.

Published: November 2020

Despite most children with cerebral palsy (CP) now living within typical life spans, little is known about how the effects of CP unfold across the life course and impact participation in everyday life during adulthood. In this study, we explored the experiences of 38 adults growing older with CP. Data were gathered using semi-structured interviews focused on participants’ engagement in activities in their community and analyzed using a life course perspective to deepen our understanding of the experiences of our participants. We found that individual agency, family and social contexts, as well as larger sociocultural contexts all shaped participants’ experiences as they grew older. The findings highlight the usefulness of the life course perspective for understanding how the effects of a diagnosis of CP unfold over time. Further use of this perspective can better inform health care services to meet the needs of adults with CP aging with a lifelong disability.
Alone in a Time of Pandemic: Solo-Living Women Coping With Physical Isolation

For people in single households, living alone has become literal and absolute during the social-distancing measures related to COVID-19 and can lead to decreased health and wellbeing. In this article, we examine how solo-living women think, feel, make sense of, and practice COVID-19-related social-distancing measures and, consequently, physical isolation. During lockdown, we interviewed 23 solo-living women between the ages of 25 and 69 years living in Slovenia. We present three levels of responses to social-distancing measures: cognitive, affective, and behavioral. We identified dissonances between these levels of responses, and we learned that affective responses play a significant role in shaping one’s orientation toward and respect for the social-distancing measures.

Published: November 2020

Background:

Among the 39,782 newly HIV diagnosed individuals in the U.S., 17% were aged 50+. Although premature aging, morbidity, and mortality are issues for older people living with HIV that threaten their quality of life, less attention has been focused on end of life (EOL) discussions.

Objectives:

To examine predictors of EOL discussions with significant others, family members, and friends.

Methods:

Cross-sectional design was used for this study guided by the The Socio Ecological Model (SEM). Sample: 119 Black and 19 Hispanic women aged 50+ living with HIV.

Results:

Predictors of EOL discussions were education, living with a partner, religiosity, and pain, which were at the individual-intrapersonal level of the SEM.

Discussion:

Findings from this study have important implications for health policy makers and clinicians because they cast a bright light on the substantial continued effort that is needed to improve EOL discussions.
Is Perfectionism Always Dysfunctional? Looking into Its Interaction with Activity Patterns in Women with Fibromyalgia

Published: November 2020

The intrinsically adaptive or maladaptive nature of certain activity patterns in fibromyalgia (FM) has been put into question. The role of contextual factors related to their influence on functional limitation is required. Perfectionism complicates the ability to cope of these patients. The aim of the study has been to analyze the moderating role of perfectionism between activity patterns and functional limitation. The sample were 228 women with FM. Moderation analyses were conducted with the PROCESS Macro. Activity avoidance and excessive persistence were associated with poorer functionality, regardless of perfectionism. Pain avoidance and task persistence were more strongly associated with FM impact in women with high or moderate levels of perfectionism. In a clinical setting adapting the recommendations given to patients according to their level of perfectionism would be justified. Pain avoidance might be inadvisable at high levels of perfectionism, and task persistence is recommendable especially when perfectionism is high.
Practice Patterns, Work Environments, and Job Outcomes of Rural and Urban Primary Care Nurse Practitioners

Published: November 2020

As nurse practitioners (NPs) are increasingly relied on to deliver primary care in rural communities, it is critical to understand the contexts in which they work and whether they are characterized by work environments and infrastructures that facilitate the provision of high-quality patient care. This study compares urban and rural NPs using data from a survey of 1,244 primary care NPs in Arizona, California, New Jersey, Pennsylvania, Texas, and Washington. While rural and urban NPs have a number of similarities in terms of demographic characteristics, practice patterns, and job outcomes, they also have noteworthy differences. Rural NPs report higher levels of independent practice, fewer structural capabilities that facilitate quality care, and poorer relationships with physicians. Health care organizations in rural communities may need to invest in work environments and infrastructures that facilitate high-quality care and autonomous practice for NPs.
Intersection of Intimate Partner Violence and Pre-Exposure Prophylaxis: Exploring HIV Worry and PrEP Acceptability Among Women
Authors: O’Malley Teagen L. , Egan James E. , Hawk Mary E. , Krier Sarah E. , Burke Jessica G.
Published: November 2020

This article examines the prevalence of recent and lifetime intimate partner violence (IPV) and association with pre-exposure prophylaxis (PrEP) acceptability among women seeking care at an urban family planning clinic ( N = 145). We found high prevalence of recent (40%) and lifetime IPV (71%). Almost a third of participants reported being worried about HIV risk, 70% were willing to take PrEP, and 71% of women who disclosed recent IPV were willing to take PrEP. Findings provide direction for research, practice, and policy attention needed around the context of IPV to focus development of a woman-centered PrEP intervention.

Published: November 2020

Objectives

The aim of this study was to define the clinical characteristics of cats referred for evaluation of subclinical cardiac murmurs, and, secondarily, to identify predictors of echocardiographic identification of cardiac disease.

Methods

One hundred and sixty-three apparently healthy cats with subclinical murmurs were retrospectively enrolled. Medical records of cats older than 1 year of age referred for the evaluation of subclinical murmurs were reviewed. Cats were considered healthy if clinical signs of systemic disease or cardiac disease were not reported and cats were not receiving cardiac medications. Logistic regression was used to identify clinical variables that predict echocardiographic identification of cardiac disease.

Results

One hundred and eight cats (66.3%) had echocardiographic evidence of cardiac disease with hypertrophic cardiomyopathy being the most common (80.5%). Left atrial enlargement was uncommon; in 90% of cats with echocardiographically identified cardiac disease, the left atrial aortic ratio from two-dimensional echocardiography was <1.51. Cats with cardiac disease were more likely to be male ( P = 0.016), weigh more ( P <0.01) and have a murmur of intensity ⩾3/6 ( P = 0.019) than cats without cardiac disease. Murmur intensity ⩾grade 3/6 ( P = 0.01) and male sex ( P = 0.01) were independent predictors of echocardiographic evidence of cardiac disease in multivariable analysis.

Conclusions and relevance

The majority of cats referred for evaluation of subclinical cardiac murmurs have cardiac disease. Based on left atrial dimensions, cardiac disease is generally mild. Male sex and a loud cardiac murmur are associated with the identification of cardiac disease.
