Speech acts addressed to Hadza infants in Tanzania: Cross-cultural comparison, speaker age, and camp livelihood
Authors: Abels Monika , Kilale Andrew , Vogt Paul
Published: November 2020

This study deals with speech acts addressed to Hadza infants in Tanzania, a group that has traditionally lived off hunting and gathering. Three research questions are addressed: How do Hadza speech acts compare with those found in previous studies in other cultures? Are there differences between child and adult speakers? And do speech acts differ with camp livelihood patterns? Speech acts are seen as a part of language socialization, which reflects overarching cultural values and socialization goals. The results indicate that Hadza infants experience many requests for action/imperatives—a way of expressing hierarchies—more than the infants in the comparative cultural communities, in spite of the fact that hunter–gatherers have been described as egalitarian in the past. Children’s and adults’ speech acts differ in several ways: adults use more requests for action and information (questions) with infants, while children use more assertives. Finally, the comparison of camp livelihoods revealed differences mainly between camps living off tourism and those that are more isolated from outside influence. The former use more imperatives, the latter more vocatives. The results are discussed in terms of cultural change toward more hierarchical structure related to livelihood activities, particularly tourism, and different activities that children and adults engage in when interacting with infants.

Published: November 2020

A component analysis is an approach where two or more independent variables are evaluated as a package and independently. The approach is used to assess and identify which component of a treatment package is the most effective. The purpose of this review is to document the application of component analyses to improve or mitigate non-academic behaviors with individuals with disabilities. We identified 21 research articles that used a component analysis to evaluate treatment packages with students who were identified as having or at-risk for a disability in classroom and/or alternative settings. Results from reviewing 21 articles (22 cases) indicate that 11 intervention packages had a single component that was critical for successful behavior change. Two articles suggested the entire intervention package was necessary while nine articles did not report a critical component or had variable results pertaining to critical components. The benefits and drawbacks of using component analyses for single case research are discussed. Implications for future research are also presented.
Hypertrophic Pachymeningitis of the Internal Auditory Canal Induced by a Labyrinthine Fistula Complicated With Cholesteatoma
Authors: Park Kyeong Suk , Shin Bong-Jin , Jang Chul Ho
Published: November 2020

Hypertrophic pachymeningitis (HP) is defined by inflammation and thickening of the dura mater, and the etiologic factors are idiopathic or secondary to various conditions. To date, HP in the internal auditory canal (IAC) has rarely been reported. There have only been 3 reports of HP in the IAC. Magnetic resonance imaging showed enhancement of along the IAC and vestibule. After antibiotic treatment, enhancement was reduced with visible seventh and eighth nerves. The patient underwent tympanomastoidectomy. To our knowledge, this is the first case of HP associated with a labyrinth fistula complicated by cholesteatoma. We report MRI image with literatures.

Published: November 2020

Prostate cancer (PC) is prone to bone metastases, but very rarely it can spread to soft tissues. In the head and neck region, PC can metastasize to the orbital soft tissue, causing various symptoms such as vision loss. In this report, we describe the case of a 79-year-old man with PC metastasis in the orbital apex. He presented to an ophthalmologist at our hospital with progressively worsening vision in his left eye over 3 to 4 months. He complained of a drooping eyelid in the same eye; thus, intracranial disease was suspected. Closer inspection with head computed tomography revealed a space-occupying lesion from the orbit to the posterior ethmoid sinus, and he was referred to our department. He had a history of PC, and we performed endoscopic sinus surgery for the diagnosis of malignancy, including metastasis of PC. As a result, the mass was diagnosed as PC metastasis by pathological examination. The patient began androgen blockade therapy and 3 months postoperatively, magnetic resonance imaging revealed that the extraconal orbital mass had decreased significantly. It is important to determine the metastases of PC in the paranasal region when the patient has a preexisting medical history.
MTurk Research: Review and Recommendations
Authors: Aguinis Herman , Villamor Isabel , Ramani Ravi S.
Published: November 2020

The use of Amazon’s Mechanical Turk (MTurk) in management research has increased over 2,117% in recent years, from 6 papers in 2012 to 133 in 2019. Among scholars, though, there is a mixture of excitement about the practical and logistical benefits of using MTurk and skepticism about the validity of the data. Given that the practice is rapidly increasing but scholarly opinions diverge, the Journal of Management commissioned this review and consideration of best practices. We hope the recommendations provided here will serve as a catalyst for more robust, reproducible, and trustworthy MTurk-based research in management and related fields.
Creation and renunciation in Ricoeur’s political ethics of compromise
Authors: Deweer Dries
Published: November 2020

Ricoeur interpreted the work of compromise as a creative process to imagine a new world by projecting ourselves into other people. The challenge of compromise is to learn to tell our own story differently within the contours of a broader collective narrative, in compliance with the paradigm of translation. As such, Ricoeur’s political ethics of compromise is at risk of highlighting the element of creation, which refers to the social imagination of a shared vision of a better society, at the cost of recognition of the element of renunciation, which refers to the reciprocal shelving of ideas and desires that the other side considers to be truly intolerable. However, I argue that we can read a delicate connection between forgetting, forgoing and forgiving in Ricoeur’s thought. It is, then, the model of forgiveness, as part of the paradigm of translation, that gives due respect to the importance of renunciation through the emphasis on the unjustifiable, for which renunciation even cannot suffice. The ‘poetics of pardon’ brings creation and renunciation together and, by doing so, it highlights that compromise always remains an object of hope.
Bringing the problem home: The anti-slavery and anti-trafficking rhetoric of UK non-government organisations
Authors: Turnbull Nick , Broad Rose
Published: November 2020

Rhetoric is a way to explain policy problem framing by recognising the practical necessity to persuade audiences in contextual situations. Modern slavery and human trafficking is a complex and emotive problem, simplified through rhetorical demands to motivate an audience of supporters. This article analyses rhetoric by 212 UK anti-trafficking and anti-slavery non-government organisations (NGOs) to uncover rhetorical practices and their effects on policy framing, supplemented by archival research to compare past and present anti-slavery oratory. Our data show NGOs use rhetoric to motivate supporters and promote a humanitarian problem frame, in opposition to a state-driven security frame. Findings confirm other research in identifying an emphasis on female victims and on sexual over labour exploitation. Past and present rhetoric are equivalent in terms of liberal, Christian values (ethos) and appeals to pathos through sympathy for victims. Historical rhetoric is distinctive in arguing for the equal human status of slaves, whereas contemporary activists argue victims are denied agency. Contemporary rhetoric represses the question of migration, whereas past rhetoric is more deliberative. Rhetoric varies with the requirements of persuasion related to contextual distance, between unlike humans in the past, but in regard to geographical distance today.
Speaking to algorithms? Rhetorical political analysis as technological analysis
Authors: Dillet Benoit
Published: November 2020

In the last few years, research studies and opinion pieces have tried to account for the new polarisation and dealignment of US politics after Trump and the post-Brexit UK politics. It is now well-established both by academic research and by Facebook’s own research that Facebook leads to more polarisation in its users’ political views, but rhetorical analysis has not yet accounted for the role played by algorithms in political communication and persuasion. What does social media do to rhetoric? The situation of speech in social media is often treated like in a public sphere when it should not be. This misconception prevents rhetorical studies to take into consideration the question of technology. By using the recent literature in critical algorithm studies, I develop a new approach in rhetorical criticism. I argue here that the increasing agency that algorithms have acquired in delivering and mediating rhetoric means that we must consider the role played by intermediaries when examining rhetorical situations. This paper sheds light on what I call the four conditionalities of algorithms on rhetoric: (1) programmed speech content, (2) the verticalisation of political communication, (3) the new biases produced by digital media, and (4) the rhetorical machine learning.
The implementation of Holland Self-Directed Search to employed higher education graduates: A comparison between sighted adults and adults with visual impairments
Authors: Papakonstantinou Doxa , Papadopoulos Konstantinos
Published: November 2020

In general, the occupational choices of individuals with visual impairments do not appear to be significantly different from the ones of the sighted individuals, despite the narrowed occupational possibilities offered to them. This study aims to explore (a) the range of occupational possibilities that according to the Self-Directed Search (SDS) most closely resemble the personality types of adults with visual impairments and sighted adults, (b) the differences between the occupational possibilities suggested by the SDS among adults with visual impairments and sighted adults, and (c) the differences between the current occupational choices and the occupational possibilities according to the SDS of adults with visual impairments and sighted adults, and the comparison among them. The sample consisted of 44 adults with visual impairments and 44 sighted adults, aged 24 to 44 years. All participants were higher education graduates and occupationally active. The occupational possibilities suggested by the SDS show the clear inclination of people with visual impairment toward social occupations. On the contrary, the SDS shows the inclination of the sighted adults toward the enterprising and the investigative occupations. The results of the statistical analysis showed that there are no differences between the two groups (visually impaired and sighted) in terms of the Iachan index – an index that determines the congruence between two SDS codes, representing the current occupations and the occupations proposed by the SDS application. The results could be practically implemented for the expansion of individuals with visual impairment occupational choices based on their occupational possibilities.
Prevalence and Correlates of Intimate Partner Violence Experience Among Partners of Naval Personnel in Lagos, Nigeria
Authors: Igwe Chinedu Paul , Yusuf Oyindamola B. , Fawole Olufunmilayo I.
Published: November 2020

Background

Military personnel are one of the high risk groups recognized as perpetrators of intimate partner violence (IPV). Little is known about IPV experience of partners of naval personnel. This study determined the prevalence and correlates of IPV experience among partners of naval personnel.

Methods

A cross-sectional survey of 435 male and female partners of naval personnel selected using the multistage sampling technique from the Navy Barracks in Lagos, Nigeria was conducted. Data were collected using a 40 item interviewer-administered questionnaire between August and September 2017. Univariate, bivariate and multivariate analysis was done to identify the predictors of partners’ experience of IPV. Analysis was done at p-value ≤0.05.

Results

The mean age of the respondents was 32.7 ± 7.86yrs and 72% were females. The lifetime prevalence of any IPV experience was 40.7% (with 74.4% of this experienced by females, CI: 0.81–1.91). The prevalence of controlling behaviour, psychological, sexual, economic and physical IPV were 31.5%, 16.3% 12.4%, 12.0% and 8.5% respectively. There was a positive association between experience of IPV and respondents’ occupational status (p < 0.0001), lifetime experience of physical (p < 0.0001), sexual abuse (<0.0001), and history of childhood abuse (p < 0.0001). After adjustment for confounders, age (AOR = 2.11, CI = 1.07–4.16), occupational status (AOR = 4.56, CI = 2.30–9.02), history of childhood abuse (AOR = 2.10, CI = 1.26–3.49,) and partners’ alcohol use (AOR = 3.41, CI = 1.38–8.39) remained significant factors influencing experience of IPV.

Conclusion

The prevalence of IPV experience among partners of naval personnel was high. Being unemployed, experience of abuse in childhood and having a partner who consumed alcohol increased partners’ vulnerability to IPV. Naval personnel would benefit from marital counseling and training on non-violence conflict resolution strategies.
Ablation therapy using a low dose of radioiodine may be sufficient in low- to intermediate-risk patients with follicular variant papillary thyroid carcinoma
Authors: Li Fuxin , Li Wei , Gray Katherine D. , Zarnegar Rasa , Wang Dan , Fahey Thomas J.
Published: November 2020

Objectives

Follicular variant papillary thyroid carcinoma (FVPTC) is treated similarly to classical variant papillary thyroid carcinoma (cPTC). However, FVPTC has unique tumour features and behaviours. We investigated whether a low dose of radioiodine was as effective as a high dose for remnant ablation in patients with FVPTC and evaluated the recurrence of low-intermediate risk FVPTC.

Methods

Data from cPTC and FVPTC patients treated with I-131 from 2004 to 2014 were reviewed. Demographics, tumour behaviour, lymph node metastasis, and local recurrence data were compared between FVPTC and cPTC patients. Then, low-intermediate risk FVPTC patients were divided into low, intermediate, and high I-131 dose groups, and postoperative I-131 activities were analysed to evaluate the effectiveness of I-131 therapy for thyroid remnant ablation.

Results

In total, 799 cases of FVPTC (n = 168) and cPTC (n = 631) treated with I-131 were identified. Patients with FVPTC had a larger primary nodule size than cPTC, but lymph node metastases and local recurrence were more prevalent in cPTC than in FVPTC. For the low-, intermediate-, and high-dose groups, success rates of ablation did not differ (82.0%, 80%, and 81.3%, respectively).

Conclusion

FVPTC differs from cPTC in behaviour. Low-dose ablation may be sufficient in FVPTC patients with low-intermediate disease risk.
Pregnancy in a patient with endometrial tuberculosis by in vitro fertilization: a case report
Authors: Wang Ying , He Chihua , Chen Ligang
Published: November 2020

Female genital tuberculosis is an important cause of infertility in developing countries where tuberculosis is endemic. However, the true incidence of genital tuberculosis is unknown because symptoms and signs are usually minimal, making its detection difficult. We herein report a case of subfertility due to endometrial tuberculosis. The patient had primary infertility and planned to utilize assisted reproductive technology because of bilateral fallopian tube obstruction. She underwent hysteroscopy and endometrial biopsy. The biopsy revealed epithelioid cells and multinuclear giant cells in the interstitium, and tuberculosis of the endometrium could not be excluded. Chest computed tomography showed secondary pulmonary tuberculosis in the upper left lung. A tuberculin test was positive, and a sputum culture of Mycobacterium tuberculosis was negative. The clinical diagnosis was secondary pulmonary tuberculosis. Considering the above findings in combination with the endometrial biopsy results, we concluded that the patient had endometrial tuberculosis. She underwent antituberculosis treatment for 6 months, after which the endometrial tuberculosis resolved and she achieved pregnancy by in vitro fertilization.
Posaconazole aggravates vincristine-related hypertension in children with acute lymphoblastic leukemia: a case report
Authors: Lin Chao , Chen Guohua , Huang Junbin , Cheng Yucai , Xu Yahong , Zhang Airun , Xue Hongman , Chen Chun
Published: November 2020

Vincristine-related secondary hypertension is rare. This study reports two children who were treated with vincristine for acute lymphoblastic leukemia (ALL) and posaconazole for fungal infections who experienced vincristine-related secondary hypertension. Blood pressure normalized in both children after halting the drugs and providing antihypertensive treatment. Thus, posaconazole can interact with vincristine and induce secondary hypertension in children with ALL. As an adverse event, this interaction is a rare occurrence.

Published: November 2020

Intratracheal ectopic thyroid (ITET) is a rare disease, with limited cases reported in the literature. ITET is an unusual congenital abnormality and can be easily mistaken for a respiratory illness. We present a case of a 61-year-old man with a history of slight discontinuous hemoptysis for 2 years. A tracheal mass, which appeared to be connected to the left thyroid gland, was found by chest computed tomography scan. Ultrasound revealed one suspiciously malignant, solid and hypoechoic nodule in the left thyroid gland. After the thyroid origin of the mass was confirmed by bronchoscopic biopsy, the patient underwent segmental resection and anastomosis of the trachea, together with left thyroidectomy. Histopathology of the tracheal tumor showed adenomatous hyperplastic ITET, and the orthotopic left thyroid gland showed nodular goiter with atypical adenomatous hyperplasia. Clinical suspicion is warranted in patients presenting with a tracheal tumor seemingly connected to the thyroid gland, particularly in patients who have imaging features suggestive of a malignant tumor in the orthotopic thyroid but without confirmative histopathology of malignancy before surgery.
Castoriadis, racist and anti-racist ontologies
Authors: Nicolacopoulos Toula , Vassilacopoulos George
Published: November 2020

Castoriadis explains racism as a mode of hatred of the other and as a feature of the self-institution of heteronomous societies built on ethnocentrism. At the level of the psychical human being he identifies two forms of racist fixation on others: hatred of the other as the flip-side of self-love and as the other side of self-hatred, which he analyses, respectively, as a mode of pseudo-reasoning and as unconscious desire. We argue that attention to the ontology that underpins the modern European subject’s epistemological deployment of racism in the context of coloniality reveals the limits and a blindspot of Castoriadis’s analysis.

Authors: Bradshaw Catherine P. , Pas Elise T. , Debnam Katrina J. , Johnson Sarah Lindstrom
Published: November 2020

This study presents findings from a 58 high-school group-randomized controlled trial testing the effectiveness of training in a multitiered system of supports for behavior (MTSS-B) framework, which was leveraged to reduce students’ risk for emotional and behavior disorders. The trial tested the impact of MTSS-B, which included (a) training in the broader MTSS-B framework that went beyond the existing Tier 1 (school-wide PBIS) training offered by the state; (b) project-provided coaching and technical assistance supports; and (c) integration and training in evidence-based behavioral or social-emotional programs at Tiers 2 and/or 3. We reported effects of MTSS-B on implementation of positive behavior supports across all three tiers using the Schoolwide Evaluation Tool (SET) and Individual Student Systems Evaluation Tool (ISSET), as well as on external observations of teachers’ use of classroom management strategies. Results indicated significant effects on multiple SET subscales and significant reductions in teachers’ use of reactive behavior management.

Published: November 2020

To explore the protective mechanism of L-arginine against T-2 toxin-induced apoptosis in mouse Leydig cells, we investigated whether L-arginine can prevent T-2 toxin-induced apoptosis in mouse Leydig cells and explored the underlying mechanisms. Leydig cells were isolated and cultured with control, T-2 toxin (10 nM), L-arginine (0.25, 0.5, and 1.0 mM), and T-2 toxin (10 nM T-2 toxin) + L-arginine (0.25, 0.5, or 1.0 mM) for 24 h. Cells and supernatants were harvested to examine proliferation of the cells, the apoptosis rate, activity of caspase-3 and mitochondria, and the gene expression levels of Bcl-2, Bax, PARP, and caspase-3. Results showed that proliferation and mitochondrial activity of Leydig cells were inhibited by administration of T-2 toxin. Bcl-2 gene expression levels was decreased, while the gene expression levels of Bax and PARP were increased, which could trigger mitochondria-mediated apoptosis, activate downstream caspase-3, and then increased caspase-3 at both activity and gene expression levels. The expression of the Bcl-2 gene was upregulated and the expression of Bax, caspase-3, and PARP gene were downregulated when L-arginine was added to the cultured cells. The results of this study showed that L-arginine could block T-2 toxin-induced apoptosis in mouse Leydig cells by regulating specific intracellular death-related pathways.

Evidence for massage therapy (MT) in hospice patients remains limited. We conducted a prospective pilot study on MTs impact on quality of life of hospice patients and caregivers. Patient-caregiver dyads were enrolled if patients scored ≥5 on pain, depression, anxiety, or well-being using the revised Edmonton Symptom Assessment System Revised (ESAS-r). The patient received MT weekly for up to 3 massages with assessments completed at baseline, after each massage, and 1 week after the final massage for patients and at baseline and 1 week after final massage for caregivers. A satisfaction survey was completed at study completion. A pro-rated area under the curve (AUC) was utilized to assess the primary endpoints of change in ESAS-r for patient ratings of pain, depression and anxiety as well as the Linear Analogue Self-Assessment (LASA). Median difference scores (end of study value)-(baseline value) for each participant and caregiver were calculated. Of 27 patients and caregivers enrolled, 25 patients received MT. Fifteen patients completed all 3 MT sessions and were given the final symptom assessment and satisfaction survey and their caregivers completed final assessments. The proportion of patients considered success (AUC > baseline) in the primary endpoints were the following: pain 40.9%, depression 40.9%, anxiety 54.5%, LASA 54.5%. Median difference scores were largely zero indicating no significant temporal change in symptoms. Patients were highly satisfied with MT. This pilot study indicated that MT was a feasible and well-received intervention in our population of patients with inadequately controlled symptoms.
Generating the tool path directly with point cloud for aero-engine blades repair
Authors: Xiao Wenlei , Liu Guiyu , Zhao Gang
Published: November 2020

Aero-engine is an essential component of the aircraft. Due to the high cost of raw materials and precise structure, the maintenance cost of aero-engine is great. By repairing worn blades rather than replacing them with new ones, the aero-engine maintenance cost can be reduced effectively. For repairing worn blades, existing methods mainly generate tool path based on the reconstructed surface with the aid of CAM software. In this paper, an effective tool path generation method for repairing blades after additive manufacturing process is presented, which overcomes the low efficiency and complicated process weakness of existing methods. The tool path is generated directly with point clouds without surface fitting. By splitting point cloud and analyzing geometric parameters of points, machining areas could be recognized from the entire blade model. The cutter location point is generated by extending on the normal vector direction of the corresponding point. The five-axis tool path could be obtained by connecting cutter location points in turns. Tool path optimization is further studied after the generation process. These algorithms eliminate the time consumption caused by surface fitting operations, and could generate five-axis tool paths for repairing aero-engine blades efficiently.
Influence of the rotary friction welding parameters on the microhardness and joint strength of Ti6Al4V alloys
Authors: Nu Ho Thi My , Loc Nguyen Huu , Minh Luu Phuong
Published: November 2020

In this study, Ti6Al4V rods were butt-welded by rotary friction welding. The experimental results show that the weld quality, in terms of the tensile strength and hardness, decreases radially. Therefore, the radius of the welded parts that are viable for rotating friction welding is limited because the areas located far from the centre of the axis have poor mechanical properties. The parameter that impacts the tensile strength and microhardness the most during rotary friction welding of Ti6Al4V is the axial pressure, which includes the friction pressure and forging pressure. A high forging pressure produces fine, equiaxed, and recrystallized grain structures in the welded joint, resulting in a high tensile strength and microhardness. In addition, an increased forging pressure can be used in rotary friction welding to reduce the radial differences in the mechanical properties of the welded joints.
Computation of residual stresses, distortion, and thermogravimetric analysis of Inconel 625 weld joints
Authors: Sivakumar J , Korra Nanda Naik , Vasantharaja P
Published: November 2020

In the current investigation, Inconel 625 weld joints were fabricated by Activated tungsten inert gas (A-TIG) and Tungsten inert gas (TIG) welding techniques. The joint configurations employed square butt and V groove edge preparations. Residual stresses measurement was carried out by X-ray diffraction using the Proto iXRD measurement system. Distortion in weld joints was estimated by measuring the vertical displacement on the grids marked on the weld joints before and after welding by using an electronic height gauge. Weldment revealed distinctive microstructure, peak tensile residual stress, and angular distortion. A-TIG weld joint exhibited lower residual stresses and distortion compared to the TIG weld joint. Thermogravimetric analysis (TGA) has inferred that the fusion zone of A-TIG and TIG weldments revealed better hot corrosion resistance at high temperatures.
‘Those people who chose us’: Discursive construction of identity and belonging in the context of Quebec’s 2018 provincial elections
Authors: Bosworth Yulia
Published: November 2020

In the climate of the growing diversification of the ethnocultural landscape, Quebecers of French-Canadian background, often viewed as mistrustful of ethnic minorities, have been faced with the challenge of renegotiating the symbolic boundaries of what it means to be a Quebecer. This study investigates discursive construction of identity and belonging in a multi-text body of discourse generated in the context of the French-language party leader debates in the run-up to Quebec’s 2018 provincial elections, which brought to power the center-right Coalition Avenir Québec. A close textual analysis of discourse produced by the party leaders and by debate viewers commenting on the Facebook page of Radio-Canada during the debates’ live stream, following the research program of Critical Discourse Analysis, demonstrates an enduring ethnic bias in the conceptualization of Quebec identity by the dominant ingroup – Francophone Quebecers of French-Canadian origin – one that puts in jeopardy the inclusive, civic Quebec identity promoted in official discourse of the Quebec government.
Unifying instrumental variable and inverse probability weighting approaches for inference of causal treatment effect and unmeasured confounding in observational studies
Authors: Liu Tao , Hogan Joseph W
Published: November 2020

Confounding is a major concern when using data from observational studies to infer the causal effect of a treatment. Instrumental variables, when available, have been used to construct bound estimates on population average treatment effects when outcomes are binary and unmeasured confounding exists. With continuous outcomes, meaningful bounds are more challenging to obtain because the domain of the outcome is unrestricted. In this paper, we propose to unify the instrumental variable and inverse probability weighting methods, together with suitable assumptions in the context of an observational study, to construct meaningful bounds on causal treatment effects. The contextual assumptions are imposed in terms of the potential outcomes that are partially identified by data. The inverse probability weighting component incorporates a sensitivity parameter to encode the effect of unmeasured confounding. The instrumental variable and inverse probability weighting methods are unified using the principal stratification. By solving the resulting system of estimating equations, we are able to quantify both the causal treatment effect and the sensitivity parameter (i.e. the degree of the unmeasured confounding). We demonstrate our method by analyzing data from the HIV Epidemiology Research Study.

Authors: Lawrence Babatunde , Doorasamy Mishelle , Sarpong Prince
Published: November 2020

The objective of the study was to comparatively assess the impact of credit risk on the performance of big and small banks in South Africa. Data from audited financial reports of 14 commercial banks were obtained and divided into two panel data sets and analysed using the R-Studio software version 3.5.1 to assess the impact of capital adequacy ratio (CAR), non-performing loan to gross loan (NPLGL), loan-to-deposit ratio (LTDR), leverage ratio (LR), board gender diversity (BGD), with bank size (total asset) and AGE as control variables, on performance, (return on asset [ROA] and return on equity [ROE]). The findings of the study revealed that non-performing loan (NPL), CAR, LR, LTDR and age of banks all have significant and greater impact on performance, as measured by ROA, of small banks when compared with big banks. Surprisingly, NPL was revealed to have a lesser impact on the ROE of small banks as compared to the ROE of big banks but showed no impact on the ROA of big banks during the period of 2008–2017.
Dutch judicial entrepreneurship towards legitimizing intellectual property rights
Authors: Jayaraman Krishnamani
Published: November 2020

In its recent judgment in the Sisvel v. Xiaomi case, the Court of Appeal of the Hague has demonstrated how European national legal systems and judiciary therein strive to uphold legitimacy of the intellectual property system. Involving dimensions of both substantive patent law and competition law, the case emphasized proportionality etched in European Union law to determine the legitimate cohesive balance for stakeholder economic interests in the protection, enforcement and use of intellectual property rights. This case note documents the salient features of the judgment and further comments on striking legal concepts that marked the case.
The Reproductive Health Priorities, Concerns, and Needs of Women in Midlife: A Feminist Poststructuralist Qualitative Analysis
Authors: Alspaugh Amy , Im Eun-Ok , D. Reibel Melody , Barroso Julie
Published: November 2020

Reproductive health research rarely involves the inclusion of women over 40, creating a large knowledge gap regarding women in midlife. Women continue to have reproductive health needs, concerns, and priorities up to the point of menopause that should be examined to improve reproductive health outcomes and provide individualized care. In-depth, individual, semi-structured interviews were conducted with 20 women between the ages of 40 and 55 who had not reached menopause and did not have a permanent method of sterilization. Using the feminist poststructuralist tenets, three major themes were identified: (a) knowledge acquisition during the perimenopause, (b) subjectivity regarding family planning, and (c) the agency of aging. Participants spoke to a need for reproductive health that listens to their lived experience, addresses menopause clinically and positively, and encourages autonomously driven health priorities. Further research on effective nonhormonal contraception, education on perimenopausal symptoms, and healthy aging is necessary.
Designing an “Ideal” Substance Use Disorder Treatment Center: Perspectives of People Who Have Utilized Medications for Opioid Use Disorder
Authors: Andraka-Christou Barbara , Randall-Kosich Olivia , Totaram Rachel
Published: November 2020

Treatment preferences of people with opioid use disorder (OUD) have been underexplored, especially among those with a history of utilizing medications for opioid use disorder (MOUD). Therefore, we sought to understand preferred characteristics of substance use disorder treatment centers among people recovering from OUD with a history of MOUD utilization. We recruited 30 individuals from eight states through snowball sampling initiated at three syringe exchange programs. Telephone interviews were audio-recorded and transcribed in 2018–2019. Inductive thematic analysis in Dedoose software occurred iteratively with recruitment. The following were “ideal” treatment center themes: a menu of treatment options, including MOUD and nonspiritual peer support groups; an integrated system with multiple care levels (e.g., outpatient, residential); a harm reduction approach, including for goal setting and success measures; adjunctive support services (e.g., housing); and employees with recovery experience and professional education. Many preferences directly related to core principles of person-centered care and harm reduction.

Published: November 2020

In this article, we explore the context and determinants of pod-mod electronic cigarette (ECIG) use among college students aged 18 to 24 in the United States. We conducted semi-structured interviews with 55 students ( M age = 20 years, 56% female, 65% White) on three campuses in the Northwest, Midwest, and Southeast. We performed a thematic analysis. Students described ECIG use by peers, increased ECIG exposure and prevalence in college, and school-related stress as reasons for vaping. Pod-mod features such as convenience, design, easy concealment, and flavors made vaping more appealing. Negative aspects of vaping included addiction, cost, and possible health consequences. Most viewed vaping as a college behavior and intended to quit after graduation. Our results show that the college environment plays a major role in young adult ECIG use. These findings can inform the development of targeted interventions to prevent and control uptake of ECIGs by young adults.

Published: November 2020

The debate around ethics review boards (IRBs) has assumed an increasingly central place in academic practice and discourse. In this article, we summarize a unique workshop (study-group) that convened at the University of Haifa, attended by 27 academics from around the globe, representing nine countries in four continents. The participants presented data and points of view, which served as the basis for an open, interdisciplinary discussion. The group developed a set of recommendations, including working toward a transition from a review system to an advisory and validation system; focusing on respectful research approach to participants, rather than “ethical” research; building a procedure that focuses on feedback, rather than the process itself; recognizing that a unified examination need not necessarily be standardized; and constructing a feedback procedure in which researchers can respond to the review of their research.

Untreated pain and pain management with opioids are independent precipitating factors for delirium. This retrospective study evaluated the relationships among pain severity, its management with opioids, and the onset of delirium in older adult patients admitted to the surgical intensive care unit (SICU). Consecutive patients aged 65 or greater admitted to the SICU over a 5-month period were examined ( n = 172). When assessed using a multivariable general estimating equation model, opioids (chi-square [χ2], 12.34, p = .0004), but not pain (χ2, 3.31, p = .0688) were significant in predicting next-day delirium status. Controlling for pain, patients exposed to opioids were 2.5 times more likely to develop delirium than patients not exposed (95% Confidence Interval: 1.44–4.36). Our data shows that opioid administration predicted the onset of next-day delirium. In an effort to prevent delirium, future research should focus on opioid-sparing pain management approaches to mitigate pain and delirium.
Meeting art with words: the philosopher as anthropologist
Authors: Ingold Tim
Published: November 2020

Taking up Rietveld’s challenge for philosophers to join with artists in investigating the questions of how to live better, this comment argues (a) that this conjunction of philosophy and art is already underway in the discipline of anthropology, (b) that it need not be limited to non-verbal investigations and (c) that a focus on the performative power of words enables us to close the gap between visual and textual expressions.
Second Job Holding Among Direct Care Workers and Nurses: Implications for COVID-19 Transmission in Long-Term Care
Authors: Baughman Reagan A. , Stanley Bryce , Smith Kristin E.
Published: November 2020

One reason that nursing homes are a primary source of COVID-19 infections and deaths in the United States may be that workers hold multiple jobs. We use 2010-2019 Current Population Survey data to document the rate of second jobholding among nursing and long-term care workers. On average, 6.41% of personal care and nursing aides and 6.23% of licensed practical nurses and registered nurses hold second jobs; second job holding rates are 35% and 32% higher than those of other workers, respectively. Both wages and hours in the primary job are negatively associated with the probability of holding a second job for personal care and nursing aides, while lower hours are more strongly correlated with a second job for registered nurses and licensed practical nurses. Many of these workers move across health settings from their first to second jobs, and 15% of second jobs for personal care and nursing aides are in other “essential” occupations.

This article aimed to determine the association between the Affordable Care Act young adult mandate and suicidal behavior. From 2007 to 2013, we used the Nationwide/National Inpatient Sample and National Poison Data System to examine suicide attempt, and Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research to examine suicide. We aggregated each outcome by quarter/year and conducted a difference-in-differences linear regression to compare young adults aged 19 to 25 years with those 27 to 29 years before and after implementation. There were not statistically significant associations between the mandate and suicide attempt inpatient hospitalizations (unstandardized beta coefficient [ b] = −0.72, p = .12, standard error [ SE] = 0.42) and percentage of poisoning cases due to suspected suicidal intent ( b = 0.23, p = .19, SE = 0.16). There was a statistically significant association when examining suicide prevalence ( b = −0.03, p = .01, SE = 0.001). The results suggest that health insurance may buffer against but is unlikely to reverse the increasing suicide rate.
A Collaborative Community College Sexual Violence Prevention and Response Effort: Climate Study Results to Assess Impact
Authors: Potter Sharyn J. , Moschella Elizabeth A. , Moynihan Mary M. , Smith Delilah
Published: November 2020

Although 2-year institutions report higher rates of sexual violence (SV) than 4-year institutions, few resources exist to address SV on these campuses. The present study describes and assesses the impact of a 3-year initiative to engage personnel and students at seven 2-year colleges and community professionals to increase the effectiveness of SV prevention and response strategies. We administered a climate survey during the first and third year of this initiative. Compared with 2017 participants, 2019 participants reported increases in awareness of campus resources and perceptions of SV. Implications and suggestions for prevention and response efforts at 2-year institutions are discussed.
Municipal Cybersecurity: More Work Needs to be Done
Authors: Preis Benjamin , Susskind Lawrence
Published: November 2020

As governments have digitized their operations, they have opened themselves to cyberattacks, resulting in harmful disruptions to government services. The scholarly world has been slow to pick up on this growing risk. Professional associations have conducted studies of their own, and produced recommendations, but few scholars have looked closely at cybersecurity practices at the municipal level. The interconnectedness of local infrastructure—across and among agencies and levels of government—makes it hard to figure out what is happening. In this paper, we urge scholars from multiple disciplines to examine the dangers created by the cross-linkages that characterize local cybersecurity. We examine the existing academic research, and demonstrate the significant growth in cybersecurity practice that has cropped up in spite of the relative sparsity of academic work. Theory and practice need to catch up with each other.
Do Social Inequalities in Smoking Differ by Immigration Status in Young Adults Living in an Urban Setting? Findings From the Interdisciplinary Study of Inequalities in Smoking

Published: November 2020

Objectives:

We assessed whether social inequalities in smoking observed among young adults born in Canada were also apparent in same-age immigrants.

Methods:

Data were drawn from an investigation of social inequalities in smoking conducted in an urban setting (Montreal, Canada). The sample included 2077 young adults age 18 to 25 (56.6% female; 18.9% immigrants who had lived in Canada 11.6 (SD 6.4) years on average). The association between education and current smoking was examined in multivariable logistic regression analyses conducted separately in young adults born in Canada and in immigrants.

Results:

About 19.5% of immigrants were current smokers compared to 23.8% of young adults born in Canada. In immigrants, relative to those with university education, the adjusted odds ratios (OR) (95% confidence interval) for current smoking were 1.2 (0.6, 2.3) among those with pre-university/vocational training and 1.5 (0.7, 2.9) among those with high school education. In non-immigrants, the adjusted ORs were 1.9 (1.4, 2.5) among those with pre-university/vocational training and 4.0 (2.9, 5.5) among those with high school.

Conclusion:

Young adults who had immigrated to Canada did not manifest the strong social gradient in smoking apparent in young adults born in Canada. Increased understanding of the underpinnings of this difference could inform development of interventions that aim to reduce social inequalities in smoking.
Emotion regulation difficulties and psychopathology among Pakistani adolescents
Authors: Zafar Huma , Debowska Agata , Boduszek Daniel
Published: November 2020

The main aim of this study was to examine the associations between emotion dysregulation and psychopathology in adolescence. A representative sample of 1,500 adolescent students (50% female) aged 12 to 19 years ( M = 15.08, SD = 1.44) was recruited from schools and colleges located in the province of district Punjab, Pakistan, using a stratified sampling technique. Structural equation modeling (SEM) was used to test associations between five dimensions of emotion regulation difficulties and five forms of psychopathology by gender (male/female). The model provided an adequate fit to the data among girls and boys. In the model tested among boys, seven positive associations between emotion regulation difficulties and psychopathology variables were found. The model tested with girls included one negative and 13 positive associations between the study variables. Findings can be used for designing universal prevention programs to prevent the development of psychopathology.
