The Appellate Body’s Power to Interpret the WTO Agreements and WTO Members’ Power to Disagree with the Appellate Body
Authors: Fukunaga Yuka
Published: December 2019

The United States criticizes the Appellate Body for ‘making law’ by interpreting and applying the World Trade Organization (WTO) agreements in disregard of the intention of WTO members. The criticism of the United States is not without legitimate basis in that Members have few tools with which they may weigh in on the interpretation of the WTO agreements, even if the Appellate Body makes an erroneous interpretation. As much as the Appellate Body’s contribution to the security and predictability of the multilateral trading system warrants praise, the dysfunction of legislative and political mechanisms to counterbalance the growing de facto ‘authority’ of the Appellate Body should be a cause for concern. Against this background, this article proposes a new mechanism that would allow Members to disagree with interpretations by the Appellate Body and pronounce their own interpretations of the WTO agreements. The mechanism would be built upon ‘interpretative declarations.’
Does ‘Action Viewing’ Really Exist? Perceived Dynamism and Viewing Behaviour
Authors: Brinkmann Hanna , Williams Louis , Rosenberg Raphael , McSorley Eugene
Published: December 2019

Throughout the 20th century, there have been many different forms of abstract painting. While works by some artists, e.g., Piet Mondrian, are usually described as static, others are described as dynamic, such as Jackson Pollock’s ‘action paintings’. Art historians have assumed that beholders not only conceptualise such differences in depicted dynamics but also mirror these in their viewing behaviour. In an interdisciplinary eye-tracking study, we tested this concept through investigating both the localisation of fixations (polyfocal viewing) and the average duration of fixations as well as saccade velocity, duration and path curvature. We showed 30 different abstract paintings to 40 participants — 20 laypeople and 20 experts (art students) — and used self-reporting to investigate the perceived dynamism of each painting and its relationship with (a) the average number and duration of fixations, (b) the average number, duration and velocity of saccades as well as the amplitude and curvature area of saccade paths, and (c) pleasantness and familiarity ratings. We found that the average number of fixations and saccades, saccade velocity, and pleasantness ratings increase with an increase in perceived dynamism ratings. Meanwhile the saccade duration decreased with an increase in perceived dynamism. Additionally, the analysis showed that experts gave higher dynamic ratings compared to laypeople and were more familiar with the artworks. These results indicate that there is a correlation between perceived dynamism in abstract painting and viewing behaviour — something that has long been assumed by art historians but had never been empirically supported.
Emotions in fear appeals: Examining college students’ attitudes and behavioural intentions towards colorectal cancer prevention in Taiwan
Authors: Li Shu-Chu Sarrina , Lu Pei-Chi , Chen Shih-Chieh
Published: December 2019

Objectives:

One criticism of the extended parallel process model (EPPM) is its lack of focus on the role of emotion and its relation to behaviour change. Another criticism of the EPPM is regarding its proposition that threat and efficacy have a moderating effect on recipients’ attitudes and behaviours. This study aimed to examine emotions and the interaction effects of threat and efficacy to understand their effects on attitudes and behavioural intentions towards colorectal cancer prevention.

Methods:

The study adopted a pretest–posttest experimental design to collect data from a sample of college students. There were 631 participating students, but the total number of eligible subjects in this study was 402 students.

Findings:

Analysis shows that (1) anxiety plays a significant role in the reception of fear-appeal messages because it not only directly influences behavioural intentions but is also a full mediator in allowing perceived threat to affect intentions; (2) emotions influence subjects’ behavioural intentions but not their attitudes; and (3) perceived threat is more effective in changing subjects’ attitudes, while perceived efficacy is more influential in changing behavioural intentions.

Conclusion:

This study found that it was anxiety rather than fear that made a positive contribution to the effectiveness of fear-appeal messages. These findings showed that the high-threat/high-efficacy group achieved the best persuasive outcomes, followed by the high-threat/low-efficacy and the low-threat/high-efficacy group. The low-threat/low-efficacy group obtained the least persuasive results, which supports the additive model of the EPPM.

Authors: Mertz Amanda , Cooney Danielle , Rahman Mahboob , Lacey Christopher , Burant Christopher J. , Desai Niraj
Published: December 2019

Purpose: Proton pump inhibitors (PPIs) are commonly used medications and are historically well tolerated. Recent studies have linked PPI use to the development of chronic kidney disease (CKD) and end-stage renal disease. This study investigated the impact of discontinuing PPIs on renal function in patients with CKD. Methods: We conducted a retrospective chart review of patients with established CKD, defined as 2 eGFR (estimated glomerular filtration rate) measurements of less than 60 mL/min/1.73 m2 at least 90 days apart, who were on a PPI from January 1, 2014 to December 31, 2014, with a medication possession ratio greater than or equal to 70%. We compared baseline eGFR to a final eGFR after at least 6 months of discontinuation or continuation of a PPI. After power analysis, we targeted an enrollment of 200 patients (100 in each group) to achieve a power of 0.80 and an alpha of 0.05. Summary: A total of 97 patients in the PPI discontinuation group and 100 patients in the PPI continuation group met the study inclusion criteria. Baseline eGFR in the PPI continuation group was 47.9 mL/min/1.73 m2 and 50.7 mL/min/1.73 m2 in the discontinuation group. Final eGFR in the PPI continuation group was significantly higher than baseline at 51.1 mL/min/1.73 m2 (+3.25 ± 12.8, P = .01). Final eGFR in the PPI discontinuation group was 51.8 mL/min/1.73 m2 (+1.09 ± 12.8, P = .3). The average time between baseline and final eGFRs was 270 days in the PPI continuation group and 301 days in the discontinuation group. There was no statistically significant difference in the change in eGFRs between groups (95% confidence interval [CI] = −5.48-2.03, P = .37). Conclusions: Proton pump inhibitor discontinuation after prolonged continuous use in patients with CKD was not associated with a significant change in renal function after 1 year.
Investigating the interplay between formal and informal leaders in a shared leadership configuration: A multimodal conversation analytical study
Authors: Van De Mieroop Dorien , Clifton Jonathan , Verhelst Avril
Published: December 2019

Leader identity has traditionally been associated with hierarchical position (formal leadership). Yet, while there is an increasing tendency to regard leadership as a collective and distributed process, very little is known about the interplay of formal and informal leadership as in situ social practice within a hierarchical context. Using video-recordings of naturally occurring workplace interaction as data and arguing that insights from applied linguistics can be profitably employed to address such a lacuna, we use multimodal conversation analysis (CA) to show how ‘doing’ leadership is not limited to the formal leader. Rather, through talk, gaze, the use of space, artefacts and so on, it is negotiated in subtle ways which allow informal leadership to emerge in conjunction, and in this case in conflict, with formal leadership. We conclude this article by discussing the wider implications of these findings to both leadership theory and methodologies used to investigate the ‘just whatness’ of leadership.
State labor sponsorship: The role of nation state regulation in undermining migrant employment standards
Authors: Verma SaunJuhi
Published: December 2019

Temporary worker programs are on the rise both across the globe and particularly within the United States. Established research focuses upon the impact of immigration policies as well as outcomes for migrant communities within the labor market. In contrast, my work draws attention to the population of citizen-workers who participate in cyclical migration patterns within transnational labor markets. My multi-site ethnography, consisting of 109 interviews with US guest workers, oil industry employers, and Indian labor brokers, evaluates the impact of temporary worker programs on migration patterns from India to the Middle East to the United States. (In this article, I use the counter-naming of the Middle East as Southwest Asia and North Africa (SWANA). I avoid use of colonial terminology such as Middle East to refer to the countries in the region of North Africa and West Asia. The language is archaic and perpetuates the historic referencing of Europe as the central geographic reference point.). In particular, the study evaluated a multi-country migrant recruitment chain to address the question: How does the non-citizen visa situate migrants as global labor within the transnational economy? Findings identify that non-citizen visa pathway is a contemporary mode of governance through which labor is traded among third parties. The article outlines the complicity of nation-state regulation in shaping limited economic outcomes for migrants within cyclical multi-country labor markets.

Published: December 2019

A PVA/PAAm (polyvinyl alcohol/polyacrylamide) hydrogel vascular graft reinforced by a braided fiber stent was prepared in the present work, and a series of characterizations were carried out for evaluating the comprehensive performance of the reinforced hydrogel vascular graft (RHVG), including the morphology, the mechanical properties and the biocompatibility. The results show that hydrogel with a mass ratio of 5:8 (PVA:PAAm) is the best candidate for developing an implantation-oriented vascular graft, whose overall performance is the closest to the requirements of clinical applications. The surface of the PVA/PAAm hydrogel is smooth, and the porous structure is uniform and stable. When the longitudinal strain of the RHVG was 50%, the tensile strength reached 905.6 ± 63.1 kPa, much higher than that of a swine common carotid artery (185 kPa). Moreover, the circumferential tensile strength was significantly enhanced by the integration of the stent, and the circumferential compression recovery reached 93.4 ± 6.7%, showing satisfactory structural stability. Furthermore, the suture retention force approached (9.89 ± 0.64 N), higher than that of a canine femoral artery (7.90 ± 0.36 N). More importantly, the radial dynamic compliance reached 3.11 ± 0.09% under testing pressure of 80–120 mmHg, which is 6.9 times that of a commercial expanded polytetrafluoroethylene vascular graft. Lastly, the RHVG has satisfying cytocompatibility and a low hemolysis rate. In summary, the present work may pave the way for developing a novel small-diameter vascular graft for clinical implantation.
Effects of structural parameters on the thermal insulation properties of coated carbon fiber fabrics
Authors: Zhang Qian , Zheng Zhenrong , Mao Kezhu , Zhi Wei , Luo Lijuan , Pei Xiaoyuan
Published: December 2019

In order to predict the thermal insulation performance of coated carbon fiber fabric, a numerical heat transfer model under high temperature was established. The simulation results were validated by quartz lamp ablation experiment. The experimental values were in agreement with the numerical values, and the average relative error between them was 9.47%. Furthermore, the impact of structural parameters on the thermal insulation of coated carbon fiber fabrics, by using the numerical heat transfer model, was investigated. The results show that thermal insulation for the samples is in the order of plain < 2/1 twill < 3/3 twill < 5/3 stain, when using constant structure density and yarn fineness. Thermal insulation performance of the samples dramatically increases as yarn fineness goes from 3 to 12 K. Furthermore, when the structure density increases to more than 70 ends/10 cm, the thermal insulation property shows an increasing trend.

Authors: Johnson Royel M. , Strayhorn Terrell L. , Travers Christopher S.
Published: December 2019

To ensure the effectiveness of academic advising efforts on campus and to increase Black male collegians’ use of such services, administrators must better understand how Black males experience academic advising in college. This exploratory qualitative case study aims to understand the academic advising experiences of Black males at a large urban, predominantly White institution. Participants in this study (a) experienced a number of process-related challenges, including difficulties with scheduling advising appointments and accessing their academic advisor; (b) stressed the role of race and culture in academic advising; and (c) highlighted positive outcomes of formal and informal advising. Implications for research, practice, and policy are discussed.
Social Construction, HPC Kinds, and the Projectability of Human Categories
Authors: Tsou Jonathan Y.
Published: December 2019

This paper addresses the question of how human science categories yield projectable inferences by critically examining Ron Mallon’s “social role” account of human kinds. Mallon contends that human categories are projectable when a social role produces a homeostatic property cluster (HPC) kind. On this account, human categories are projectable when various social mechanisms stabilize and entrench those categories. Mallon’s analysis obscures a distinction between transitory and robust projectable inferences. I argue that the social kinds discussed by Mallon yield the former, while classifications of biological kinds yield the latter. Classifications from psychiatry (“schizophrenia,” “hysteria”) are discussed as examples.

On this basis, it looks forward to China’s urgent geothermal exploration and development work and key technologies to be urgently developed, providing important guidance for China’s geothermal science and technology innovation and rapid industrialization development.
Diabetes Standard of Care Among Individuals Who Have Diabetes With and Without Cognitive Limitation Disabilities
Authors: Comer-HaGans DeLawnia , Austin Shamly , Ramamonjiarivelo Zo , Matthews Alicia K.
Published: December 2019

Purpose

The purpose of this study is to examine diabetes standard of care among individuals who have diabetes with and without cognitive limitation disabilities (CLDs). Individuals with CLDs are more likely to develop diabetes and less likely to participate in diabetes standard of care services compared to those without CLDs.

Methods

We used pooled cross-sectional data (2011-2016) from the Household Component of the Medical Expenditure Panel Survey (HC-MEPS). Dependent variables were utilization of dilated eye exams, foot checks, A1C blood tests, and engagement in moderate or vigorous physical exercise 5 times per week. Our independent variable was diabetes with CLDs vs diabetes without CLDs. We controlled for predisposing, enabling, and need factors.

Results

Findings suggest that individuals with diabetes and CLDs were less likely to engage in moderate or vigorous physical exercise 5 times per week compared to individuals without CLDs. For other diabetes care services, individuals with CLDs are as likely to participate in health services utilization as those without CLDs.

Conclusions

Our study supports research that indicates individuals with diabetes and CLDs were less likely to participate in physical exercise compared to individuals without CLDs. Conversely, individuals with diabetes and CLDs were just as likely to receive a dilated eye exam, have their feet checked, and have their A1C checked as individuals without CLDs, which is a very encouraging finding.
Gamifying place, reimagining publicness: the heterotopic inscriptions of Pokémon Go
Authors: Woods Orlando
Published: December 2019

This article explores the transformative effects of augmented reality mobile games on society and space. By layering playfulness onto public space through a digital interface, augmented reality mobile games create a pervasive sense of play that can be accessed by players potentially anywhere, and at any time. Games like these can therefore be understood as heterotopic inscriptions on otherwise mundane environments. Since being released in 2016, Pokémon Go has become one of the most popular augmented reality games in the world. It gamifies place by embedding digital objects within public spaces; in doing so, it can bring about a reimagination of publicness by incentivising players to engage with places – and with each other – in ways that are structured by the competitive logics of play. Through an empirical examination of the playing of Pokémon Go in Singapore, I consider how the game gives rise to new modalities of emplaced meaning, new ways of navigating the city and increasingly public performances of private play. To conclude, I argue that research should continue to explore the gamifying effects of digital technologies on everyday life.
Emotion Regulation and Job Satisfaction as Predictors of Subjective Well-being in Doctors
Authors: Sharma Prachi , Srivastava Urmila Rani
Published: December 2019

This study examined the role of emotion regulation and job satisfaction in predicting affective (positive and negative affect) and cognitive (life satisfaction) components of subjective well-being (SWB) in doctors. The predictors used were the dimensions of job satisfaction—intrinsic, extrinsic job satisfaction as well as the total score of job satisfaction and the following dimensions of intra-personal emotion regulation—cognitive reappraisal and expressive suppression. The participants included in the study were doctors from multi-specialty hospitals in Gurgaon district of Haryana. A total of 102 doctors were included in the study using convenience sampling. Correlational and step-wise multiple regression analyses were conducted to test the predictions. The results of the analysis confirmed the predictions as intrinsic job satisfaction and cognitive reappraisal significantly and positively predicted life satisfaction. The findings were discussed in the light of available research along with implications of the study and possible avenues for future research.
When is prime-time in streaming media platforms and video-on-demands services? New media consumption patterns and real-time economy
Authors: Tana Jonas , Eirola Emil , Nylund Mats
Published: December 2019

Traditional media are being surpassed by Internet media content, which can be accessed by multiple Internet-enabled devices, when and where ever, often even during night-time. The constant availability and widespread use of these streaming media or video-on-demand services have led to changes in media consumption and usage patterns and video viewing behaviour. This study explores the temporal media consumption patterns of different video-on-demand services in Finland by analysing search engine queries, with the aim to investigate when prime-time for these services occurs. The data for this study were obtained from Google Trends, between 30 September and 1 December 2017. Results show that there are clear and recurring temporal patterns for video-on-demand service interest and media consumption in Finland. Popularity in Google searches for the different video-on-demand services start to rise in the evening and peak during night-time and clear troughs are visible during the morning hours and during the day. These strong diurnal characteristics point to a strong media behaviour and makes it easy to predict trends. It is evident that peaks in primetime for streaming media services are visible at night-time and have replaced the television set prime-time. These findings on behavioural patterns and habits might have new and disruptive implications in the post-television era, both on an individual and societal level.
Arab Threat and Social Control: An Exploration of the Relationship Between Ethnic Attitudes and Punitiveness Among Israeli Jews
Authors: Metcalfe Christi , Cann Deanna
Published: December 2019

Numerous studies in the United States, as well as a smaller number of studies in other Westernized countries, have linked racial and ethnic attitudes to support for more punitive forms of crime control. The current study explores this relationship in Israel by assessing whether the degree to which Israeli Jews typify crime as an Israeli Arab phenomenon and/or resent Israeli Arabs is related to support for punitive criminal justice policies. The findings suggest that ethnic typification and resentment are related to general punitive attitudes, whereas ethnic apathy and resentment are related to greater support for the death penalty. Also, the relationship between ethnic typification and punitiveness is stronger among those who are less resentful.
Emotions, Affections, and Psychopathy Among Female Prisoners
Authors: Pinheiro Marina , Cunha Olga , Gonçalves Rui Abrunhosa
Published: December 2019

The present study intends to be a contribution to understand affections and emotions associated with female psychopathy. Although there are several studies aiming to understand psychopathy, there is still a gap in the integration of such a concept in affective dimensions, as well as a scarcity of surveys conducted in the female population. Sixty-three women confined to prison, located in the North region of Portugal, participated in this study. Participants were assessed using the Positive and Negative Affect Schedule (PANAS), the Levenson’s Self-Report Psychopathy Scale (LSRP), and the Hare’s Psychopathy Checklist–Revised (PCL-R). Results showed that only nine women presented moderate scores of psychopathy. Moreover, women with higher psychopathy scores revealed deficits in positive emotional abilities, and secondary psychopathy was related with predominance of negative affection. In the future, it would be useful to develop more effective instruments to assess emotions and affections in psychopaths.
Biocompatibility of a polymer-coated membrane possessing a hydrophilic blood-contacting layer: Adsorption-related assessment
Authors: Tagaya Masashi , Okano Shinya , Murataka Takuo , Handa Hiroki , Ichikawa Shunsuke , Takahashi Shunsuke
Published: December 2019

Objective:

Currently, the foreign surfaces of extracorporeal circulation devices are coated with an acrylate-based copolymer that creates a hydrophilic blood-contacting layer to enhance biocompatibility. Several reports of acrylate-based copolymer with respect to biocompatibility have been published; however, the adsorption of peptide compounds on acrylate-based copolymer–coated membranes still requires clarity. In this study, we aimed to understand the adsorption of several peptide compounds of various molecular weights, including albumin, lysozyme, and vancomycin, on acrylate-based copolymer–coated membranes using in vitro studies.

Methods:

Six experimental circuits consisting of acrylate-based copolymer–coated tubes and membranes, and six comprising acrylate-based copolymer–coated tubes and non-coated membranes were prepared for comparison. An experimental solution, composed of albumin, lysozyme, vancomycin, and saline, was continuously stirred in a reservoir, recirculated in each experimental circuit, and then filtered. Concentrations of albumin, lysozyme, and vancomycin were measured after 0, 15, 30, 45, 60, 90, and 120 min of recirculation. Similar experiments were performed in all the prepared circuits.

Results:

The ratio of measured values at each time point to those at 0 min was not significantly different between acrylate-based copolymer–coated and non-coated membranes for albumin and lysozyme, but differed significantly for vancomycin; the ratios were higher in acrylate-based copolymer–coated than in non-coated membranes.

Conclusion:

This study suggests that albumin is not adsorbed on either acrylate-based copolymer–coated or non-coated membranes, that lysozyme is not adsorbed on either membrane or is adsorbed at a similar rate on both membranes, and that vancomycin is less adsorbed on acrylate-based copolymer–coated membranes. Thus, acrylate-based copolymer coating could inhibit the adsorption of various peptide compounds.
Organophosphorus-hydrazides as potential reactive flame retardants for epoxy
Authors: Morgan Alexander B , Benin Vladimir , Klosterman Donald A , Sulayman Abdulhamid Bin , Mukhtar Mustafa , Galaska Mary L
Published: December 2019

For structural composites used in vehicles and aircraft, flame retardant chemistries which enhance char formation and reduce heat release are preferred. Phosphorus-based and phosphorus–nitrogen flame retardants for epoxies have been well studied to date, but phosphorus hydrazides have not been studied for their flame-retardant potential in epoxy. These hydrazides offer some novel structures and they can potentially offer a combination of vapor and condensed phase flame retardant action. A series of eight compounds were systematically investigated in this study as reactive flame retardants in a bisphenol F epoxy/aliphatic amine resin system at a level of 2.5 wt% phosphorus. Results suggest that the phosphorus hydrazides react with the epoxy during thermal decomposition, and they also release nitrogen during flaming combustion of the epoxy matrix. The observed reactions resulted in increased char yields and reduced total heat release, while simultaneously lowering heat of combustion and total smoke release.
Anglican Establishment: How is it Liberal?
Authors: Biggar Nigel
Published: December 2019

This article argues that the kind of religious establishment that currently obtains in England is sufficiently liberal in the sense that it accommodates rights to religious freedom and is compatible with political equality. What is more, insofar as it expresses a Christian anthropology, established Anglicanism can generate the ‘thick’ set of virtues necessary to make citizens capable of respecting liberal rights. In the course of defending its thesis, the argument disputes John Rawls’s description of the ‘overlapping consensus’ as one that stands free of its supporting comprehensive doctrines; and it reads Martha Nussbaum as, ironically, confirming that an established orthodoxy of some sort is inevitable.
Politics in the Service of Society: A Response to My Interlocutors
Authors: Bretherton Luke
Published: December 2019

This article is a response to Hauerwas’s, O’Donovan’s and Muir’s engagements with Christ and the Common Life. Three distinctions that operate in the book are clarified, namely that between formal and informal politics, bottom-up forms of democratic politics and top-down forms of statecraft, and social and political relations. In setting these out, the distinction between public and private is critiqued and two, interrelated moves made in the book are defended. First, that democratic politics precedes and sustains a liberal polity. And second, that human law and the state should serve the antecedent and superordinate good of association.

Published: December 2019

Precise machining of advance material like Inconel-718 is an emerging need. Selection of an appropriate optimal range of cutting parameters is quite essential to achieve the high-quality cut and is a challenging task within this domain of study. The aim of this research is to develop a robust prediction model, which can suggest the desired range of cutting parameters for accomplishing better cutting quality, precision, and geometrical accuracy. Experiments have been performed on a 300 W (CNC-PCT 300) pulsed Nd: YAG laser cutting system at various levels of input cutting parameters, namely gas pressure, standoff distance, cutting speed, and laser power. Thereafter, response surface methodology has been adopted to develop mathematical models in terms of aforementioned input cutting parameters for geometrical quality characteristics: top kerf width and bottom kerf width. These developed models have been validated by comparing the predicted values with the experimental ones. Further, these models have been optimized using the multiobjective genetic algorithm in order to ascertain the optimal range of cutting parameters pertaining to better quality cut with high precision and geometrical accuracy.
Evaluation of SA-DES and SST-DES models using OpenFOAM for calculating the flow around a train subjected to crosswinds
Authors: Li Tian , Hemida Hassan , Zhang Jiye
Published: December 2019

Detached eddy simulation (DES) has been widely applied in crosswind stability simulations of trains in recent years. As DES is a hybrid Reynolds Averaged Navier–Stokes (RANS)/large eddy simulation approach, the choice of the RANS model associated with DES is a key factor for an accurate numerical simulation. However, the influence of the RANS model on the flow around trains was not fully investigated in previous researches. In this study, DES with the Spalart–Allmaras (SA) model (SA-DES) and shear stress transport (SST) k−ω model (SST-DES) have been investigated owing to their ability to predict the surface pressure, aerodynamic forces, and the flow field around a 1/25th scale Class 390 train subjected to crosswinds. Numerical simulation results were validated with experimental data. Results show that both SA-DES and SST-DES predict similar trends of the mean flow field around the train. However, there were considerable differences observed in the position of separation points and consequently the separation and attachment lines on the roof and bottom of the train body. The SST-DES results correlated more closely to the experimental data than SA-DES for pressure coefficient on the roof and leeward surface at almost all loops. A slight difference in the side force and roll moment coefficients and a considerable difference in the lift force coefficient were observed for SA-DES and SST-DES. The side force coefficients calculated using SST-DES remain within the experimental uncertainty, whereas the lift force coefficients deviated greatly due to the omission of some underbody geometrical features. Compared to the experimental data, the SST-DES performs better than SA-DES. Therefore, the SST k−ω model is recommended for the RANS model associated with DES.
Intrasexual Competition as a Predictor of Women’s Judgments of Revenge Pornography Offending
Authors: Fido Dean , Harper Craig A. , Davis Mia A. , Petronzi Dominic , Worrall Sophie
Published: December 2019

Recent legislative developments have led to a marked increase in the empirical investigation of motivations and judgments of so-called acts of “revenge pornography” offending. In two independently sampled studies, we used moderation analyses to investigate whether higher levels of intrasexual competition predicted more lenient judgments of revenge pornography offenses as a function of sex (Study 1, N = 241), and whether such relationships would be further moderated by physical attractiveness (Study 2, N = 402). Potential covariates of callous-unemotional traits, empathy, and victimization history were controlled for. Opposing our hypotheses, we consistently observed a trend for higher levels of intrasexual competition being associated with more lenient judgments of revenge pornography offenses involving male victims by female participants. The results are discussed in terms of intrasexual competition potentially sharing variance with unobserved constructs in the wider sexological literature, and of the key relevance of these findings for future empirical investigation into judgments of nonconsensual image–based offending.
Perceived Risk and Hazards Associated With Home Health Care Among Home Health Nurses of India
Authors: Singh Ankit , Jha Ajeya , Purbey Shankar
Published: December 2019

The objective of this study is to categorize the home health nursing care activities and hazards applicable to Indian settings, into high, medium, and low priority levels with the help of risk assessment table and risk matrix. The research design is exploratory and the study is cross-sectional, A self-administered questionnaire is prepared for Indian settings based on the literature review; the content validity and the internal consistency were ensured; the mean scores and the frequencies for the activities were calculated. The severity scores for the identified 14 perceived high-risk activities were assigned with the help of the brainstorming session. The hazard of slippery floors and exposure to blood fell into high priority area (denoted by red area) with high severity and high occurrence score, similarly overloaded and unsafe electrical outlets, rushing with clients, time pressure for reaching the client’s home, and contact with chemicals fell into medium priority category (denoted by yellow area). Finally, hazards such as uncontrolled pets and verbal abuse from patients fell into low priority levels. The providers should take measures for hazards such as slippery floors, overloaded and unsafe electrical outlets, rushing with clients, time pressure for reaching the client’s home, exposure to blood, and contact with chemicals, as these hazards fell into high-medium severity rating with high-medium probability.
Media Presentation of Homicide: Examining Characteristics of Sensationalism and Fear of Victimization and Their Relation to Newspaper Article Prominence
Authors: Wong Jennifer S. , Harraway Victoria
Published: December 2019

This study explores how characteristics of a homicide affect prominence of the story in a newspaper (including front-page placement, photographs, article length, and a composite measure of these items). Using a sample of 3,998 newspaper articles from the Vancouver Sun (2004–2015), we examine how homicides that (a) may be deemed “sensational crimes” or (b) may incite fear of personal victimization are related to greater prominence. Findings suggest the presence of sensational characteristics have a greater impact on article prominence than the presence of fear-inciting characteristics. Implications for public perception of homicide events and policy are discussed.
Effect of mode of delivery and background noise on speech characteristics of talkers in a classroom environment
Authors: Subramaniam Nithya , Ramamurthy K
Published: December 2019

Global and acoustic–phonetic correlates of speech intelligibility are important measures of talker intelligibility. Speech characteristics have been evaluated using speech samples that involve reading pre-administered passages under controlled environments. In classrooms, lecturing is the mode of speech delivery. The presence of noise from ceiling fans and other external noise hinder the speech communication process. This study evaluated the talkers’ speech characteristics utilizing recordings from graduate students under reading and lecturing modes and in the presence and absence of noise generated by ceiling fans. The acoustical conditions under which talkers delivered their speech were characterized using octave band U50 values. Global and acoustic–phonetic correlates of talker intelligibility were measured and the variation in correlates of speech intelligibility was statistically analyzed. The results revealed that talkers significantly modified their speech characteristics relevant to intelligibility across modes of speech delivery and in the presence of noise. Fundamental frequency measures such as F0-mean and F0-SD and durational measures such as speech and pause rates were all found to be higher for lecture mode of delivery. Talkers showed similar vowel-articulatory changes under the two modes of delivery. When lecturing in the presence of noise, talkers significantly reduced the length of pauses and also utilized a combination of vowel-articulatory strategies to overcome the presence of noise. The results suggest the need to investigate talkers’ speech adaptation in real classroom environments in terms of correlates of speech intelligibility and to reconsider classroom acoustical guidelines in view of both listener and talker intelligibilities.

Published: December 2019

During the 2016 election, Donald Trump castigated unauthorized immigrants as “murderers and rapists.” During his presidency, he continued the use of this rhetoric, explicitly linking unauthorized migrants to threatening narratives. Here, we consider three questions: Did Donald Trump and his immigration positions serve as an “anxiety trigger” for Latina/os? Are individuals with contextually stigmatized attributes especially sensitive to Trump and his policy proposals? Is Spanish language itself, an attribute negatively stigmatized in the context of the immigration issue, sufficient to increase deportation anxiety? Utilizing survey experiments of Latina/os, we demonstrate that exposure to a Trump immigration cue is sufficient to increase anxiety about deportation. We also demonstrate that stigmatized attributes predict anxiety, but do not moderate the effect of the Trump cue. Lastly, we provide evidence that survey language affects anxiety among Latina/os. In Studies 1 ( n = 736) and 2 ( n = 1,040), we show that exposure to information about Trump’s immigration agenda significantly increases reports about deportation anxiety. In Study 3 ( n = 1,734), we show that the Trump exposure condition induces heightened anxiety but that Latina/o attributes (language proficiency and use, immigration status, assessed phenotype) and identity strength have an independent effect on deportation anxiety. In Study 4 ( n = 775), we randomized bilingual respondents into Spanish or English language survey protocols and found that comparable bilinguals exposed to Spanish language report higher levels of anxiety compared to English-language survey takers.

The dual potential capacity model was developed in the authors’ previous studies to estimate the shear strengths of reinforced concrete members, in which the shear crack concentration factor was adopted as the key concept of the proposed approach. In this study, a shear test program was carefully prepared and conducted on five reinforced concrete beam specimens to investigate the crack development, propagation, and merging behavior of critical shear cracks. To this end, concrete cover thickness, diameter of reinforcement, presence of skin reinforcement, and shear reinforcement ratio were taken as the main test variables. From the experiments, the crack merging and concentration phenomena were clearly observed, and the crack concentration factors were estimated from the measured flexural and shear crack widths and spacings. The crack concentration factors were compared to those estimated by the dual potential capacity model, and the shear strengths of the test specimens were also compared with those estimated by the dual potential capacity model and other models in detail.
Beyond the veil: Kaupapa Māori gaze on the non-Māori subject

Kaupapa Māori methodologies in Aotearoa New Zealand have often been applied to content of immediate and direct relevance to Māori communities. Some of these include research about aspects of cultural revitalisation or examinations of the position Māori occupy within broader ethnic disparities, particularly in health and social outcomes. This article seeks to expand the application of Kaupapa Māori paradigms to research topics outside ‘te ao Maori’ (the Māori world). We argue that the Kaupapa Māori theorising of a Māori visual arts and culture scholar can provide crucial insights on white privilege in Aotearoa New Zealand with a view to addressing disparities and creating more embracing and equitable perspectives of belonging, citizenship and nationhood.
Electronic Health Record and Problem Lists in Leeds, United Kingdom: Variability of general practitioners’ views
Authors: Martin Pablo Millares , Sbaffi Laura
Published: December 2019

Data sharing of Electronic Health Records from general practices to secondary care in Leeds occurs through the so-called Leeds Care Records, which collects a specific set of codes from primary care, known as ‘Active Problems’, and presents it to the user. Variability on its content is a known issue. To explore general practitioners’ views on their use of ‘Active Problems’ and on sharing data, so lessons could be learnt on how to homogenise and improve shared data. Assessing Leeds general practitioners’ views through two parallel processes (60 online surveys and 17 interviews). General practitioners feel they do not have the time nor the training required for keeping a shared approach to concise and current Problem Lists in electronic patient records. Action is needed to reduce current variability, and to improve the quality of shared information. Some types of codes currently present in Problem Lists have very little support among general practitioners who consider the focus should be on long-term conditions and probably adding current acute diagnoses and life expectancy items and not omitting sensitive information. There is a perceived need of training and time to update Problem Lists if their quality is to improve.
Creating a relational arts-based academy for persons living with dementia
Authors: Mitchell Gail J , Jonas-Simpson Christine , Richards Joy , Brown Susan , Bitove Vonna
Published: December 2019

A hospital–university collaboration has created an innovative learning Academy for persons living with dementia. Authors propose essential foundations for creating a different culture of dementia care: a home-like, judgement free place; a relational space focused on artistic expression and discovery; and, the marriage of learning with a deep respect for difference and growth. An array of challenges and insights highlight the commitments required to create and sustain real change. Partnerships with community organizations and schools merged relational philosophy-based research, teaching–learning, and art to generate new patterns of innovative practices. The commitment of the Academy is to relational arts-based inquiry focused on relationships, life enrichment, and engagement in a space where everyone thrives.
Strategies used by people with Alzheimer’s disease for outdoor wayfinding: A repeated observational study
Authors: Olsson Annakarin , Skovdahl Kirsti , Engström Maria
Published: December 2019

This study aimed to describe the wayfinding strategies used during outdoor walks by people with Alzheimer’s disease. Inspired by an ethnographic approach, observations and conversations during repeated outdoor walks with five people with Alzheimer’s disease living in their own homes were conducted. Data were analyzed using qualitative content analysis. The wayfinding strategies the participants described were: (1) landmarks, (2) used their senses, (3) stopped, looked around, and thought, (4) walking the same way or loop and in familiar areas, and (5) only walked in places and on routes where they could see other people and houses. Using wayfinding strategies might help people with Alzheimer’s disease to be independent during outdoor walks, and discussing these strategies with relatives and nursing care staff may help finding people with Alzheimer’s disease if lost outdoors. Wayfinding during the winter might be facilitated if temporary and changeable objects are avoided in people with Alzheimer’s disease’s walking route.
How do we integrate skills and content in classics? An inquiry into students’ use of sources
Authors: Goodwin Karl A , Quinlan Kathleen M
Published: December 2019

Engagement with primary sources is a key feature of arts and humanities subjects, particularly classics and ancient history. Recent instructional trends emphasise integrating skills with content, particularly in the first year of higher education. We investigate how successfully first-year university students used a variety of sources in an integrated skills and content course, through analysis of 84 final essays. Most students used four to nine sources in a 1500 word essay, but only one type of ancient source. The findings express the need to move from debates about whether to integrate skills or not, to greater discuss how key discipline-specific skills are integrated into content-based courses. Cognitive apprenticeship theory, and a thematic approach used in museum education, are used to reflect on the findings and discuss how teachers might better support students in this key aspect of the discipline.
Formalizing shape-change: Three-dimensional printed shapes and hygroscopic material transformations
Authors: Vazquez Elena , Gürsoy Benay , Duarte Jose Pinto
Published: December 2019

Shape-changing materials have become increasingly popular among architects in designing responsive systems. One of the greatest challenges of designing with these materials is their dynamic nature, which requires architects to design with the fourth dimension, time. This article presents a study that formalizes the shape-changing behavior of three-dimensional printed wood-based composite materials and the rules that serve to compute their shape-change in response to variations in relative humidity. In this research, we first developed custom three-dimensional printing protocols and analyzed the effects of three-dimensional printing parameters on shape-change. We thereafter three-dimensional printed kirigami geometries to amplify hygroscopic material transformation of wood-based composites.
