Cross-Modal Cue Effects in Motion Processing
Authors: Hanada G. M. , Ahveninen J. , Calabro F. J. , Yengo-Kahn A. , Vaina L. M.
Published: October 2018

The everyday environment brings to our sensory systems competing inputs from different modalities. The ability to filter these multisensory inputs in order to identify and efficiently utilize useful spatial cues is necessary to detect and process the relevant information. In the present study, we investigate how feature-based attention affects the detection of motion across sensory modalities. We were interested to determine how subjects use intramodal, cross-modal auditory, and combined audiovisual motion cues to attend to specific visual motion signals. The results showed that in most cases, both the visual and the auditory cues enhance feature-based orienting to a transparent visual motion pattern presented among distractor motion patterns. Whereas previous studies have shown cross-modal effects of spatial attention, our results demonstrate a spread of cross-modal feature-based attention cues, which have been matched for the detection threshold of the visual target. These effects were very robust in comparisons of the effects of valid vs. invalid cues, as well as in comparisons between cued and uncued valid trials. The effect of intramodal visual, cross-modal auditory, and bimodal cues also increased as a function of motion-cue salience. Our results suggest that orienting to visual motion patterns among distracters can be facilitated not only by intramodal priors, but also by feature-based cross-modal information from the auditory system.

Verification of an Approximate Thermodynamic Equation with Application to Study on Arctic Stratospheric Temperature Changes
Authors: Liu Renqiang , Fu Yanyan
Published: October 2018

Temperature changes in the Arctic lower stratosphere on both short- and long-term time scales are critical for changing the magnitude of ozone losses in the Arctic vortex. In this paper, an approximate month-to-month temperature change equation is constructed and extended to a new form for decade-to-decade changes. Then we provide a verification of these equations and show an example of an application for partitioning between the dynamical and radiative contributions to the Arctic lower-stratospheric temperature decadal changes, as well as the trends, using the European Centre for Medium-Range Weather Forecasts (ECMWF) interim reanalysis (ERA-Interim) data during the period of 1980–99. At 100 hPa, the month-to-month Arctic temperature increment is a small term compared to the dynamical heating and diabatic heating, which are largely canceling terms with maximum magnitudes in November–April and October–March, respectively. However, it is not the case for their decadal changes and the decadal change of the Arctic current-month temperature compared to those of the regressed dynamical heating and radiative heating, where the current-month decadal changes and the corresponding trends are approached except in March and a rough agreement exists between these trends and those reported in other studies. The dynamical plus diabatic heating term and the temperature increment, as well as their decadal changes, are roughly balanced during the annual oscillation. However, some departures exist in both cases because of the large deviations or uncertainties of relevant terms and also probably due to the quasigeostrophic approximation and the eddy heat flux approximation of the dynamical heating, and a restricted condition of the eddy heat flux approximation is given at the end.

Published: October 2018

Since the second phase of the North American Land Data Assimilation System (NLDAS-2) was operationally implemented at NOAA/NCEP as part of the production suite in August 2014, developing the next phase of NLDAS has been a key focus of the NCEP and NASA NLDAS teams. The Variable Infiltration Capacity (VIC) model is one of the four land surface models of the NLDAS system. The current operational NLDAS-2 uses version 4.0.3 (VIC403), the research NLDAS-2 used version 4.0.5 (VIC405), and the NASA Land Information System (LIS)-based NLDAS uses version 4.1.2.l (VIC412). The purpose of this study is to evaluate VIC403 and VIC412 and check if the latter version has better performance for the next phase of NLDAS. Toward this, a comprehensive evaluation was conducted, targeting multiple variables and using multiple metrics to assess the performance of different model versions. The evaluation results show large and significant improvements in VIC412 over the southeastern United States when compared with VIC403 and VIC405. In other regions, there are very limited improvements or even deterioration to some degree. This is partially due to 1) the sparseness of USGS streamflow observations for model parameter calibration and 2) a deterioration of VIC model performance in the Great Plains (GP) region after a model upgrade to a newer version. Overall, the model upgrade enhances model performance and skill scores for most parts of the continental United States; exceptions include the GP and western mountainous regions, as well as the daily soil moisture simulation skill, suggesting that VIC model development is on the right path. Further efforts are needed for scientific understanding of land surface physical processes in the GP, and a recalibration of VIC412 using reasonable reference datasets is recommended.
The Oral Microbiota Is Modified by Systemic Diseases
Authors: Graves D.T. , Corrêa J.D. , Silva T.A.
Published: October 2018

Periodontal diseases are initiated by bacteria that accumulate in a biofilm on the tooth surface and affect the adjacent periodontal tissue. Systemic diseases such as diabetes, rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) increase susceptibility to destructive periodontal diseases. In human studies and in animal models, these diseases have been shown to enhance inflammation in the periodontium and increase the risk or severity of periodontitis. All 3 systemic diseases are linked to a decrease in bacterial taxa associated with health and an increase in taxa associated with disease. Although there is controversy regarding the specific oral bacterial changes associated with each disease, it has been reported that diabetes increases the levels of Capnocytophaga, Porphyromonas, and Pseudomonas, while Prevotella and Selenomonas are increased in RA and Selenomonas, Leptotrichia, and Prevotella in SLE. In an animal model, diabetes increased the pathogenicity of the oral microbiome, as shown by increased inflammation, osteoclastogenesis, and periodontal bone loss when transferred to normal germ-free hosts. Moreover, in diabetic animals, the increased pathogenicity could be substantially reversed by inhibition of IL-17, indicating that host inflammation altered the microbial pathogenicity. Increased IL-17 has also been shown in SLE, RA, and leukocyte adhesion deficiency and may contribute to oral microbial changes in these diseases. Successful RA treatment with anti-inflammatory drugs partially reverses the oral microbial dysbiosis. Together, these data demonstrate that systemic diseases characterized by enhanced inflammation disturb the oral microbiota and point to IL-17 as key mediator in this process.

Authors: Qian Miao , Wang Jinghan , Xiang Zhong , Zhao Zhewei , Hu Xudong
Published: October 2018

To investigate the drying characteristics of thin cotton fabric for reducing the energy consumption during the heat setting process, a two-dimensional heat and moisture transfer model considering lateral heat and moisture transmission under the impingement drying condition was developed in this study. The curves of the variation in fabric temperature and moisture content over time were obtained and the results indicate that the drying rate increases with the decrease in the moisture content in the fabric. In addition, non-uniform distributions of temperature and moisture on the fabric over time were obtained. The drying time per unit area on the fabric was found to increase with time. Further, experiments were conducted to test the heat and moisture transfer performance of the fabric, and the experimental results agree reasonably well with the calculations.
Troubling Meanings of “Family” for Young People Who Have Been in Care: From Policy to Lived Experience
Authors: Boddy Janet
Published: October 2018

This article seeks to trouble the concept of “family” for young people who have been in out-of-home care, by reflecting on the continuing significance (and troubles) of family relationships beyond childhood. The analysis draws on two cross-national studies in Europe: Beyond Contact, which examined policies and systems for work with families of children in care, and Against All Odds?, a qualitative longitudinal study of young adults who have been in care. Policy discourses that reify and instrumentalize the concept of family—for example, through the language of “contact,” “reunification,” and “permanence”—neglect the complex temporality of “family” for young people who have been in care, negotiated and practiced across time and in multiple (and changing) care contexts, and forming part of complex, dynamic and relational identities, and understandings of “belonging” for young adults who have been in care.
Reframing Central American Migration From Narrative Journalism
Authors: Palau-Sampio Dolors
Published: October 2018

Over the past decade, some journalists and media have addressed Central American migration to the United States from an investigative and narrative reporting perspective, providing a more reliable and accurate portrait of the main characters and their underlying reasons for making the move. This article examines how an ethnographic and analytical approach in combination with narrative techniques can improve the coverage of complex issues such as migration, providing more detailed and complete information than conventional media presents. The qualitative analysis focuses on five projects, including the crossmedia On the Road—with a long-form reportage, a book of photographs, and a documentary—and four multimedia documents released by Central American platforms, in some cases in partnership with U.S. media and foundations. The results emphasize that new reporting techniques and coverage inspired in slow journalism can help to reframe migration in a radically different way.
Smart urbanism and smart citizenship: The neoliberal logic of ‘citizen-focused’ smart cities in Europe
Authors: Cardullo Paolo , Kitchin Rob
Published: October 2018

This paper examines the neoliberal ideals that underpin participation and citizenship in the smart city and their replication mechanisms at the European level, particularly focusing on the work of the European Innovation Partnership for Smart Cities and Communities. The research consisted of three levels of data generation and analysis: a discourse analysis of policy documents and project descriptions of the 61 Commitments in the European Innovation Partnership for Smart Cities and Communities ‘citizen-focus’ cluster; interviews with a dozen stakeholders working on citizen engagement in a small sample of European Innovation Partnership for Smart Cities and Communities flagship projects; and twenty interviews with city officers and corporate exhibitors at the 2017 Smart City Expo and World Congress. We contend that smart cities as currently conceived enact a blueprint of neoliberal urbanism and promote a form of neoliberal citizenship. Supra-national institutions like the European Innovation Partnership for Smart Cities and Communities act at a multi-scalar level, connecting diverse forms of neoliberal urbanism whilst promoting policy agendas and projects that perform neoliberal citizenship in the spaces of the everyday. Despite attempts to recast the smart city as ‘citizen-focused’, smart urbanism remains rooted in pragmatic, instrumental and paternalistic discourses and practices rather than those of social rights, political citizenship, and the common good. In our view, if smart cities are to become truly ‘citizen-focused’, an alternative conception of smart citizenship needs to be deployed, one that enables an effective shift of power and is rooted in the right to the city, entitlements, community, participation, commons, and ideals beyond the market.
Ondansetron – a promising adjunctive treatment for persistent schizophrenia
Authors: Kulkarni Jayashri , Thomas Natalie , Hudaib Abdul-Rahman , Gavrilidis Emorfia , Gurvich Caroline
Published: October 2018

Background:

Ondansetron is a serotonin 3 receptor antagonist widely used to prevent nausea and vomiting in pregnancy and in patients receiving chemotherapy. There is growing evidence that adjunctive ondansetron treatment improves symptomatology associated with schizophrenia, particularly with respect to the positive, negative and cognitive symptoms. Further studies that are applicable to real world practice are required to assess the efficacy and effectiveness of this treatment, which could be readily and rapidly translated into clinical practice.

Aims:

This randomized control trial compared adjunctive (8 mg/daily) ondansetron or placebo to commonly prescribed atypical antipsychotics for people suffering with chronic schizophrenia ( ClinicalTrials.gov NCT01121042).

Methods:

The study involved 85 outpatients aged 18–65 years with a diagnosis of schizophrenia or schizoaffective disorder who participated in a two-arm randomized control trial.

Results:

Longitudinal analyses revealed adjunctive ondansetron provided significant improvement in the cognitive domain ( p<0.05) as measured by the Positive and Negative Syndrome Scale between baseline and week 12. The analysis of “Combination” showed ondansetron effect on Total Positive and Negative Syndrome Scale, approaching significance by week 12 ( p=0.06). No group differences were obtained in the Montgomery-Asberg Depression Rating Scale or Positive and Negative Syndrome Scale subscales.

Conclusion:

This treatment trial provides some support for adjunctive ondansetron medication as a treatment for the cognitive disorganization symptoms of schizophrenia.
Long-term comparisons of the efficacy, safety, and pregnancy outcomes of adjuvant tamoxifen plus ovarian function suppression in premenopausal Han and Zhuang Chinese patients with hormone receptor-positive early breast cancer
Authors: Tang Shicong , Zhang Qiong , Tang Xianghui , Chen Dong , Zhang Fan , Liu Jianlun , Wei Wei , Liu Dequan
Published: October 2018

Objective

To compare the efficacy, safety, and pregnancy outcomes of tamoxifen plus ovarian function suppression (OFS) between Han and Zhuang women with hormone receptor-positive breast cancer.

Methods

A total of 236 Han and 101 Zhuang women with hormone receptor-positive breast cancer who received tamoxifen plus OFS were analyzed retrospectively. Long-term disease-free survival (DFS) and overall survival (OS) were evaluated by Kaplan–Meier analysis, and adverse events and pregnancy outcomes were assessed by χ2 and Fisher’s exact-probability tests.

Results

There was no significant difference in DFS or OS between Han and Zhuang women (5-year DFS 74.57% and 77.23%, OS 85.59% and 90.01%, respectively). The incidences of endometrial hyperplasia, ovarian cysts, nausea and vomiting, fatty liver, retinitis, and thrombocytopenic purpura were similar in both groups, but Zhuang women had significantly more allergic reactions (6.93% vs. 2.12%). Pregnancy rates among women who attempted pregnancy were similar (Han, 7/138, 5.07%; Zhuang, 2/46, 4.35%).

Conclusions

OFS plus tamoxifen resulted in similar DFS and OS among premenopausal Han and Zhuang women with hormone receptor-positive breast cancer. However, Zhuang women were more likely to experience an allergic reaction. For women with fertility concerns, OFS plus tamoxifen was associated with similar pregnancy rates in Zhuang and Han women.
Is Competition Necessarily Efficient? An Answer through the History of Neoclassical Theory
Authors: Berthonnet Irène
Published: October 2018

The paper challenges the idea that neoclassical economics has demonstrated competition’s efficiency. It does so by retracing the history of Pareto’s criterion (in general equilibrium and in modern neoclassical economics), showing that it is only after a few shifts and transformations that it became an “efficiency” criterion while it was never called that in Pareto’s work. Widespread belief that competition is efficient is rather the result of ideology than of rigorous neoclassical demonstration.

Identification of waste management strategies and waste generation factors for thermal power plant sector wastes in Turkey
Authors: Demir Cansu , Yetiş Ülkü , Ünlü Kahraman
Published: October 2018

Thermal power plants are of great environmental importance in terms of the huge amounts of wastes that they produce. Although there are process-wise differences among these energy production systems, they all depend on the logic of burning out a fuel and obtaining thermal energy to rotate the turbines. Depending on the process modification and the type of fuel burned, the wastes produced in each step of the overall process may change. In this study, the most expected process and non-process wastes stemming from different power generation processes have been identified and given their European Waste Codes. Giving priority to the waste minimization options for the most problematic wastes from thermal power plants, waste management strategies have been defined. In addition, by using the data collected from site visits, from the literature and provided by the Turkish Republic Ministry of Environment and Urbanization, waste generation factor ranges expressed in terms of kilogram of waste per energy produced annually (kg/MWh) have been estimated. As a result, the highest generation was found to be in fly ash (24–63 for imported coal, 200–270 for native coal), bottom ash (1.3–6 for imported coal, 42–87 for native coal) and the desulfurization wastes (7.3–32) produced in coal combustion power plants. The estimated waste generation factors carry an important role in that they aid the authorities to monitor the production wastes declared by the industries.
Best Practices for Early Bystander Intervention Training on Workplace Intimate Partner Violence and Workplace Bullying
Authors: Lassiter Barbara J. , Bostain Nancy S. , Lentz Cheryl
Published: October 2018

The purpose of this study was to gain consensus from experts on the best practices that might be taken into account when developing early bystander intervention training programs to reduce both workplace intimate partner violence (WIPV) and workplace bullying (WB). A U.S. nationwide panel of 17 experts completed the qualitative five-round modified Delphi study. The experts were leaders or managers from business, government, not-for-profit, and academic organizations who exceeded the criteria to participate in the study. Research included the collection of data electronically to answer the research question: What do experts with experience in the area of workplace violence (WV), WB, or WIPV agree constitute the best practices that might be considered when developing a bystander training program to address WIPV or WB? In Rounds 1 and 2, participants provided their demographics and initial opinions about best practices. Likert-type scales were used as follows: Round 3, to rate agreement about which statements constituted best practices; Round 4, to rank order statements from Round 3; and Round 5, to rate the importance of each statement. Results were analyzed for top best practices. Three themes emerged: leadership, training, and people involved in the incident. Findings indicated that senior management must be committed to lead the way; that victims, targets, and bystanders need to be protected, and confidentiality must be maintained. The study was based on the concept of altruism and empathy that humans show to others experiencing crisis or suffering. Practical implications showed a clear emphasis on the critical need for leadership as the foundation for reducing all forms of violence in the workplace; training should instruct staff in how to identify WV, WB, and WIPV, when to intervene, and how to get help; and ensure that victims are treated in a supportive and caring manner.
Modelling boundary-layer transition on wings operating in ground effect at low Reynolds numbers
Authors: Roberts LS , Finnis MV , Knowles K
Published: October 2018

The transition-sensitive, three-equation k- kL- ω eddy-viscosity closure model was used for simulations of three-dimensional, single-element and multi-element wing configurations operating in close proximity to the ground. The aim of the study was to understand whether the model correctly simulated the transitional phenomena that occurred in the low Reynolds number operating conditions and whether it offered an improvement over the classical fully turbulent k-ω shear stress transport model. This was accomplished by comparing the simulation results to experiments conducted in a 2.7 m × 1.7 m closed-return, three-quarter-open-jet wind tunnel. The model was capable of capturing the presence of a laminar separation bubble on the wing and predicted sectional forces and surface-flow structures generated by the wings in wind tunnel testing to within 2.5% in downforce and 4.1% in drag for a multi-element wing. It was found, however, that the model produced insufficient turbulent kinetic energy during shear-layer reattachment, predicted turbulent trailing-edge separation prematurely in areas of large adverse pressure gradients, and was found to be very sensitive to inlet turbulence quantities. Despite these deficiencies, the model gave results that were much closer to wind-tunnel tests than those given by the fully turbulent k-ω shear stress transport model, which tended to underestimate downforce. Significant differences between the transitional and fully turbulent models in terms of pressure field, wake thickness and turbulent kinetic energy production were found and highlighted the importance of using transitional models for wings operating at low Reynolds numbers in ground effect. The k- kL- ω model has been shown to be appropriate for the simulation of separation-induced transition on a three-dimensional wing operating in ground effect at low Reynolds number.
A positive direct Coombs’ test in the absence of hemolytic anemia predicts high disease activity and poor renal response in systemic lupus erythematosus
Authors: Hanaoka H , Iida H , Kiyokawa T , Takakuwa Y , Kawahata K
Published: October 2018

We determined the clinical utility of the direct Coombs’ test in the absence of hemolytic anemia as an indicator of disease activity and therapeutic response in systemic lupus erythematosus (SLE). SLE patients without hemolytic anemia who visited our hospital from January 2016 to November 2016 were retrospectively evaluated with a direct Coombs’ test. Clinical features, including SLE disease activity index (SLEDAI), treatment and laboratory findings were analyzed. For patients with lupus nephritis, we additionally evaluated the cumulative complete renal response rate over one year after induction therapy. Among 182 patients evaluated, 10 (5.8%) patients had a positive direct Coombs’ test in the absence of hemolytic anemia. They had a higher SLEDAI ( p < 0.01), higher circulating immune complex levels ( p = 0.01), higher anti-DNA titers ( p < 0.01) and a lower complete renal response rate ( p = 0.03) compared with those who were negative. Multivariate analysis indicated that SLEDAI was an independent factor correlated with the direct Coombs’ test without hemolytic anemia (odds ratio 2.4, 95% confidence interval 1.66–4.98, p < 0.01). A positive direct Coombs’ test in the absence of hemolytic anemia may therefore represent a useful biomarker for assessing disease activity and therapeutic response.
Situating anticipation in everyday life: Using sensory methods to explore public expectations of synthetic biology
Authors: Meckin Robert , Balmer Andrew
Published: October 2018

Public involvement in technological anticipation is a common feature of contemporary sociotechnical innovation. However, most engagements abstract sociotechnical futures, rather than situating them in the everyday practices in which people are routinely engaged. Recent developments in synthetic biology have established the potential for ‘drop in’ replacements for ingredients in consumer products, particularly in flavour and fragrance markets. This article explains how a sensory methodology can be used to explore citizens’ everyday experiences and how these can be used to ground anticipation of possible sociotechnical futures. The article uses a socio-historical approach to analyse and compare two practice domains – caring for families and hygiene and personal care – to show how biosynthetic futures can disrupt existing relations between people, objects and ideas. The implications for conceptualising publics in synthetic biology and for approaches to public engagement and participation are discussed more broadly.
Professionalizing peer instructor skills in basic life support training for medical students: A randomized controlled trial
Authors: Benthem Yvet , van de Pol Eva MR , Draaisma Jos MTh , Donders Rogier , van Goor Harry , Tan Edward CTH
Published: October 2018

Background:

The Radboud university medical center designed an obligatory basic life support and first‐aid course for first‐year medical students.

Objectives:

We evaluated the value of an additional train‐the‐trainer course following European Resuscitation Council guidelines, which focuses on practical basic life support training and providing feedback, in comparison with standard in‐service instructor training.

Methods:

This study was a prospective randomized controlled trial. A total of 10 intervention instructors, 14 control instructors, and 337 first‐year medical students participated in the study. Students, blinded for the type of instructor, completed questionnaires evaluating the quality of the basic life support training (theoretical and practical) and provided feedback. The secondary endpoint was the basic life support examination to assess whether the instructors’ training influenced the quality of the participants’ basic life support.

Results:

The response rate of the questionnaire was 82% on average. No differences were found between intervention and control group concerning theoretical basic life support training. The intervention instructors scored significantly higher on practical basic life support training according to student evaluations (p < 0.001). The pass rate on basic life support examinations did not differ significantly (p = 0.669). Appreciation of given feedback was independent of instructors’ educational training.

Conclusion:

This study is the first to establish that the 12‐h train‐the‐trainer course following European Resuscitation Council guidelines improves students’ appreciation of practical basic life support training. The additional course did not influence appreciation of theoretical basic life support training or perceived feedback.
Traveler’s Mind: A Narrative-Based Account of Working and Living Mindfully
Authors: Dane Erik , Rockmann Kevin W.
Published: October 2018

Traveling to novel destinations can give rise to a state of attention referred to here as a “traveler’s mind”—a state in which two forms of a popular concept in management and organization studies, mindfulness, occur in tandem. In this essay, written as a personal narrative, I explore the nature of a traveler’s mind, discuss the conditions under which this state of attention is most likely to arise, and consider how this state connects to and informs our understanding of related concepts of note (e.g., mindfulness and sensemaking). I also propose that a traveler’s mind can be achieved not only through travel but also on a more mundane basis and highlight practices organizations and their members can adopt to foster this state of attention. Together, the observations provided here suggest that cultivating a traveler’s mind is as much a matter of mind-set as of geography.
How Shopping Mall Service Quality Affects Customer Loyalty Across Developing Countries: The Moderation of the Cultural Context
Authors: Diallo Mbaye Fall , Diop-Sall Fatou , Djelassi Souad , Godefroit-Winkel Delphine
Published: October 2018

Cross-cultural studies indicate the importance of service quality and loyalty in different nations, but they do not specify how cultural context affects the relationships between such constructs. The current research investigates whether mall service quality and its specific dimensions affect loyalty, as well as how cultural contexts moderate the relationships between these constructs in three developing countries (Morocco, Senegal, and Tunisia). With a sample of 750 real customers, the authors show that mall service quality and its specific dimensions affect customer loyalty through the positive mediation of customer satisfaction and mall perceived value. Depending on the country, service quality dimensions (mall physical aspects, reliability, problem solving, and personnel attention) have distinct effects on customer loyalty. Furthermore, mall service quality drives customer loyalty positively in Morocco and Senegal. Customer satisfaction has a positive effect on customer loyalty in Senegal and Tunisia. Due to their different cultural contexts, these three developing countries do not exhibit a homogeneous pattern.
Performance enhancement using durational model predictive control combined with backstepping control and disturbance observer for electrical drives
Authors: Liu Ying , Cheng Shanmei , Ning Bowen , Li Yesong
Published: October 2018

Model predictive control (MPC) is widely used in a cascaded structure for electrical drives, in which, the MPC is applied as inner-loop for current regulating while another controller such as proportional–integral (PI) is applied as outer-loop for speed regulating. However, the benefits of MPC for multiple targets optimizing simultaneously are not sufficiently utilized. Moreover, characteristics of these drives rely on the outer-loop controller due to the cascaded strategy, and they are parameter-sensitive. A durational MPC is proposed in this paper to optimize the speed and currents of permanent-magnet synchronous machine (PMSM) simultaneously, and it is combined with backstepping control (BSC) and disturbance observer to improve the disturbance rejection ability and parameter robustness. The nonlinear characteristics of drives are considered, and the voltage reference is constructed by combining the optimal voltage vector and virtual voltage target produced by MPC and BSC, respectively. The proposed method takes advantages of both MPC and BSC and thus provides significant performance enhancement compared with the conventional PI-base cascaded MPC. Simulation and experiment for the PMSM drives with the proposed method are conducted to prove its stability, feasibility, and efficiency.
Social Reactions to Intimate Partner Violence Disclosure Among Low-Income, Ethnically Diverse Community Women
Authors: Yndo Monica C. , Weston Rebecca , Marshall Linda L.
Published: October 2018

Friends and family members’ reactions to intimate partner violence (IPV) disclosure play an important role in social support because disclosure often precedes requests for support. Perceptions of social reactions to IPV disclosure are likely to vary by context. Yet, research is limited on the role of ethnicity and severity of physical violence in perceptions of social reactions. We examined perceptions of social reactions to IPV disclosure using data from Wave 6 interviews for Project HOW: Health Outcomes of Women. Participants ( N = 201) were asked proportionately how many friends and family reacted positively and negatively to IPV disclosure. MANOVAs revealed significant differences in perceptions of positive social reactions by ethnicity and severity.

Published: October 2018

When your residential program is full, finding emergency shelter for human trafficking and domestic violence survivors can be challenging. Advocates often spend hours calling one agency after another to locate an appropriate placement. The Safe Shelter Collaborative is an innovative technological approach to locating emergency shelter. By sending out a blast alert to certified users within a geographic network, agencies provide faster access for a greater number and diversity of survivors. This article reports on an evaluation of the Safe Shelter Collaborative and the ways it has transformed the process of finding emergency shelter.
Teacher Praise and Reprimands: The Differential Response of Students at Risk of Emotional and Behavioral Disorders

Published: October 2018

In the United States, many teachers feel underprepared to manage student classroom behavior positively. Such management is crucial for students to learn effectively, especially those with or at risk of emotional and behavioral disorders (EBD). Although increasing teacher praise and decreasing teacher reprimands may be research-based practices, more empirical evidence is required for them to be considered evidence based. The current study of 65 elementary school teachers and 239 students across three states contrasted the effects of these teacher behaviors on engagement and disruptions of students who were and were not at risk of EBD. Using structural equation modeling, we examined how the engagement and disruptions of students at risk were more sensitive to teacher praise and reprimand than the behavior of their typical peers. These results support the literature and invite teachers to consider that who they praise and reprimand is just as important as how.
Labral hypertrophy correlates with borderline hip dysplasia and microinstability in femoroacetabular impingement: a matched case-control analysis
Authors: Nwachukwu Benedict U , Gaudiani Michael A , Marsh Nathan A , Ranawat Anil S
Published: October 2018

Purpose:

The goal of this study was to: (1) investigate the association between labral hypertrophy and radiographic and computed tomography (CT) imaging measurements of dysplasia in a femoroacetabular impingement (FAI) cohort; (2) evaluate the association between physical examination parameters suggestive of microinstability and labral hypertrophy.

Methods:

A retrospective case-control study was performed. Labral hypertrophy was defined as intraoperative labral width measuring greater >4 mm. A control cohort (NL) was matched to the cases. Physical examination parameters and preoperative radiographic and CT imaging studies were reviewed.

Results:

231 hip arthroscopies for FAI were reviewed from which 42 cases of labral hypertrophy were identified (LH). In the LH group there was significantly increased hip internal rotation at 90° hip flexion compared to normal controls (13.6° ± 1 0.7° LH vs. 9.3° ± 6.2° NL; p = 0.04). On plain radiographs, the mean lateral centre-edge angle was smaller in the LH group compared to the NL group (27.6° ± 6.00° LH vs. 31.6° ± 6.59° NL; p < 0.001) and the acetabular index was larger in the LH group compared to the NL group (6.61 ± 4.18 LH vs. 4.14 ± 6.13 NL; p = 0.04). On CT imaging coronal sagittal CEA was significantly lower in LH cases compared to NL control (31.8° ± 5.30° LH vs. 35.1° ± 7.67° NL; p = 0.01).

Conclusions:

We found that patients with labral hypertrophy have radiographic and CT measurements consistent with subtle but not absolute dysplasia and physical examination findings suggestive of microinstability. We propose that labral hypertrophy can be a useful clinical tool for identifying FAI patients on the dysplasia spectrum.
Friendship and online filtering: The use of social media to construct offline social networks
Authors: Standlee Alecea
Published: October 2018

This article explores technologically integrated relationship practices among college students. Analyzing interviews of 52 participants at two very different US colleges, I explore how they construct, establish, and maintain technologically mediated social networks. This research focuses specifically on the practice of “doing homework,” in which participants conduct social media investigations of potential friends and use that data to determine if a relationship continues. Findings suggest the establishment of offline relationships includes the use of social media profiles to collect social and political attitude data on potential friends. Participants report the use of such data as essential to their decision-making processes about friendship, resulting in a potential increase in social and political homogeneity within offline social networks. These findings contribute to our ongoing understanding of the role of informational echo chambers within a technologically integrated social environment.
One of the blokes: Brewsters, branding and gender (in)visibility in New Zealand’s craft beer industry
Authors: Kuehn Kathleen M. , Parker Sophie
Published: October 2018

Beer drinking has long been valorised as a masculine performance and a social ritual. But as more women enter the craft beer industry, new opportunities emerge to reframe the cultural discourses around beer. With an interest in the stories women brewers (‘brewsters’) tell, we conducted interviews (n = 6), and a textual analysis of brand strategies (n = 10) used by women-owned beer brands in New Zealand. With an attention towards how gender identity factors into these narratives, we found that women largely reproduce the narrative trope of ‘authenticity’ utilised by craft brewers broadly. Gender identity is largely rendered invisible at the expense of promoting authenticity as a seemingly gender-neutral value. In New Zealand, however, these strategies must be contextualised in a cultural history in which beer drinking and national identity are fundamentally intertwined, and in ways that have has always been coded masculine. Our findings suggest that while branding can potentially enhance the visibility of women as legitimate producers of beer, New Zealand brewsters maintain craft beer as a Pākehā (White European) middle-class masculine cultural form.
Participatory arts in care settings: A multiple case study: Innovative practice
Authors: Broome Emma , Dening Tom , Schneider Justine
Published: October 2018

This paper describes two case studies of arts interventions in UK care settings. Visual arts and dance movement interventions were regularly held in two settings. This paper draws on data from qualitative interviews, reflective diary sheets and narrative monitoring reports to examine the content, context, and process of the arts interventions within the care settings. Activity coordinators play a crucial role in the success of arts interventions in care setting through their knowledge and support of residents. We recommend that preparatory consultations should take place between arts practitioners and care personnel, as this seems to improve participation and overall satisfaction.
Why should we bother? What are configurations for?
Authors: Hinings CR (Bob)
Published: October 2018

The main thrust of the essays by Greckhamer et al., Täuscher, and Miller is about methodologies for studying configurations, such as qualitative comparative analysis, clustering, and systems dynamics. My aim is to ask why we should be interested in configurations at all. I consider three approaches to configurational analysis: first, configurations as a basic building block in a systematic theory of organizational structure and systems; second, configurations as a generic classification tool, emphasizing that all theory should be looking for enduring patterning in elements of all kinds associated with different organizational issues and different levels of analysis; third, the use of a configurational approach to consider the properties of individual cases. I also have some observations about the future of configurational analysis.
Addressing race, racism, and commercial sexual exploitation in practice through an action-based research partnership
Authors: Gerassi Lara B , Colegrove Amanda , McPherson Deanna Kopriva
Published: October 2018

This paper analyzes the participatory research process stemming from a five-year transformative relationship between anti-trafficking coalition members (including service providers from multiple social service organizations), the coalition organizer, and a service provider who became a sex trafficking/commercial sexual exploitation researcher. We describe the collaborative process in the study design (including development of research questions, methodological and analytic planning, interview guide development, member checking, dissemination of findings, and creation of action steps) for one study, which sought to understand barriers and facilitators to service access and engagement among adult women involved in commercial sex. We analyze how our relationships enhanced methodological rigor and overall feasibility of the study, while creating a pathway to change in the community. Finally, we reflect on the role of our own diverse racial identities in collaborating on this research study, as well the implications for action.
The subjectivity of false hope and the possibility for critical hope among novice teachers
Authors: Duarte Bryan J
Published: October 2018

The current neoliberal policy regime that has dictated school reform policies such as standardized testing and performance accountability challenges the professional values of teachers. As a result, they become policy subjects who either accept or resist the neoliberal agenda. Given the high turnover of novice teachers in schools governed by neoliberal policies, this study sought to understand first-year teachers’ feelings of efficacy and career decisions. This paper applies Duncan-Andrade’s (2009) theoretical concepts of false and critical hope to the narrative experiences of three first-year teachers working in high-poverty schools. The findings indicate that teachers’ ideologies may match the false hope of equal opportunity and hard work that are embedded in the neoliberal policy regime. Additionally, first-year teachers may also develop some skepticism of the polices they are forced to implement. However, if they are unsure how to express their skepticism, they may experience hopelessness over time. This paper argues that critical hope presents an opportunity for teachers, administrators, and students to confront neoliberal policies that contradict their vision of schooling and provide a less prescriptive, more universal education. Additionally, it reveals insights into how policy regimes impact the experiences and identities of novice teachers.
Telling the Story of the Superhero and the Anti-Politician as President: Donald Trump’s Branding on Twitter
Authors: Schneiker Andrea
Published: October 2018

Given his extensive use of Twitter, the ways in which Donald Trump uses this platform are subject to a number of scholarly analyses. These generally attribute the success of Trump’s tweets to the ways in which he uses the features Twitter offers. Adopting a perspective of political marketing, I regard Donald Trump as a political product that is marketed through political branding. Drawing on the literature on celebrity politicians and based on a sample of 1469 tweets that were posted by Donald Trump’s personal Twitter account @realDonaldTrump between March 2016 and April 2017, I argue that Donald Trump’s image marketing strategy produces a new brand that distinguishes Donald Trump from his competitors and predecessors: the superhero anti-politician celebrity. The analysis furthermore shows that in contrast to the assumption formulated in the literature on celebrity politicians, this brand does not contribute to reinvigorating democracy, because it is based on contempt of the existing political system.
An Alternative to Representation: Explaining Preferences for Citizens as Political Decision-Makers
Authors: Gherghina Sergiu , Geissel Brigitte
Published: October 2018

Extensive scholarly attention is devoted to citizens’ preferences for alternative models of political decision-making. However, few efforts were made to identify who these citizens are and why they display a certain preference. To address this void in the literature, our article analyzes the determinants of preferences for citizens as decision-makers. It uses individual-level data from a 2014 survey on a probability representative sample in Germany and tests the effects of political attitudes toward institutions of representative democracy, interest in politics, and civic involvement. It controls for consumption of political news, education, and age.
