The Paralogous Krüppel-like Factors 9 and 13 Regulate the Mammalian Cellular Circadian Clock Output Gene Dbp
Authors: Knoedler Joseph R. , Ávila-Mendoza José , Subramani Arasakumar , Denver Robert J.
Published: April 2020

An intricate transcription-translation feedback loop (TTFL) governs cellular circadian rhythms in mammals. Here, we report that the zinc finger transcription factor Krüppel-like factor 9 (KLF9) is regulated by this TTFL, it associates in chromatin at the core circadian clock and clock-output genes, and it acts to modulate transcription of the clock-output gene Dbp. Our earlier genome-wide analysis of the mouse hippocampus-derived cell line HT22 showed that KLF9 associates in chromatin with Per1, Per3, Dbp, Tef, Bhlhe40, Bhlhe41, Nr1d1, and Nr1d2. Of the 3514 KLF9 peaks identified in HT22 cells, 1028 contain E-box sequences to which the transcriptional activators CLOCK and BMAL1 may bind, a frequency significantly greater than expected by chance. Klf9 mRNA showed circadian oscillation in synchronized HT22 cells, mouse hippocampus, and liver. At the clock-output gene Dbp, KLF9 exhibited circadian rhythmicity in its association in chromatin in HT22 cells and hippocampus. Forced expression of KLF9 in HT22 cells repressed basal Dbp transcription and strongly inhibited CLOCK+BMAL1-dependent transcriptional activation of a transfected Dbp reporter. Mutational analysis showed that this action of KLF9 depended on 2 intact KLF9-binding motifs within the Dbp locus that are in close proximity to E-boxes. Knockout of Klf9 or the paralogous gene Klf13 using CRISPR/Cas9 genome editing in HT22 cells had no effect on Dbp expression, but combined knockout of both genes strongly impaired circadian Dbp mRNA oscillation. Like KLF9, KLF13 also showed association in chromatin with clock- and clock-output genes, and forced expression of KLF13 inhibited the actions of CLOCK+BMAL1 on Dbp transcription. Our results suggest novel and partly overlapping roles for KLF9 and KLF13 in modulating cellular circadian clock output by a mechanism involving direct interaction with the core TTFL.

Published: April 2020

Background:

Acute kidney injury (AKI) is common among cardiac arrest survivors. However, the outcomes and predictors are not well studied.

Methods:

This is a cohort study of cardiac arrest patients enrolled from January 2012 to December 2016 who were able to survive for 24 hours post-cardiopulmonary resuscitation. Patients with anuria, chronic kidney disease (stage 5), and end-stage renal disease were excluded. Acute kidney injury (stage 1) or higher was defined using Kidney Disease: Improving Global Outcomes classification. Multivariable adjusted regression models were used to compute hazard ratio (HR) for association of AKI with risk of mortality and odds ratio (OR) with risk of poor neurological outcomes after adjusting for demographics, comorbidities, and medical therapy. Multivariable logistic regression model was used to compute OR for association of various predictors with AKI.

Results:

Of 842 cardiac arrest survivors, 588 (69.8%) developed AKI. Among AKI patients, 69.4% died compared with 52.0% among non-AKI patients. In multivariable adjusted Cox proportional hazard model, development of AKI post-cardiac arrest was significantly associated with mortality (HR: 1.35; 95% confidence interval [CI]: 1.07-1.71, P = .01) and poor neurological outcomes defined as cerebral performance category >2 (OR: 2.27; 95% CI: 1.45-3.57, P < .001) and modified Rankin scale >3 (OR: 2.22; 95% CI: 1.43-3.45, P < .001). Postdischarge dialysis was also associated with increased risk of mortality (HR: 2.57; 95% CI: 1.57-4.23, P < .001). Use of vasopressors was strongly associated with development of AKI and continued need for postdischarge dialysis.

Conclusions:

Acute kidney injury was associated with increased risk of mortality and poor neurological outcomes. There is need for further studies to prevent AKI in cardiac arrest survivors.
Exploring Nonmotor Neuropsychiatric Manifestations of Parkinson Disease in a Comprehensive Care Setting
Authors: Dhingra Amitha , Janjua A. Umair , Hack Laura , Waserstein Gabriella , Palanci Justin , Hermida Adriana P.
Published: April 2020

Parkinson disease (PD) is a debilitating neurological condition that includes both motor symptoms and nonmotor symptoms (NMS). Psychiatric complaints comprise NMS and are collectively referred to as neuropsychiatric manifestations. Common findings include atypical depressive symptoms, anxiety, psychosis, impulse control disorder, deterioration of cognition, and sleep disturbances. Quality of life (QoL) of patients suffering from NMS is greatly impacted and many times can be more debilitating than motor symptoms of PD. We expand on knowledge gained from treatment models within a comprehensive care model that incorporates multidisciplinary specialists working alongside psychiatrists to treat PD. Insight into background, clinical presentations, and treatment options for patients suffering from neuropsychiatric manifestations of PD are discussed. Identifying symptoms early can help improve QoL, provide early symptom relief, and can assist tailoring treatment plans that limit neuropsychiatric manifestations.
Rethinking the Link Between Structure and Collective Action. Capitalism, Politics, and the Theory of Social Movements
Authors: Caruso Loris , Cini Lorenzo
Published: April 2020

Social movement scholars have rarely paid attention to the transformations of capitalism as factors of social movement formation processes. This paper makes two different but complementary contributions. First, we provide a macro-social theory that connects the emergence of social movements to the capital circuit in order to embed social movement formation processes into the structural dynamics of capitalism. Exploring such dynamics is helpful to the understanding of social movements if one only looks at them by highlighting their socio-political—and not only merely economic—nature. Secondly, we show how and to what extent some institutional transformations involving the politics of advanced capitalist societies have been affected by the capital circuit and vice versa. More notably, we argue that these transformations have given rise to a political field centered on the ambivalence between two poles, namely, a regressive-oligarchic and a participative-mobilizing one, which is the domain of populist politics today.
The Governance of Public–Nonprofit Service Networks: Four Propositions
Authors: Van Puyvelde Stijn , Raeymaeckers Peter
Published: April 2020

By integrating literature on governance processes with literature on network integration, we investigate the governance of mandated lead-organization public–nonprofit service networks. We argue that the relationship between the governing public actor and the participating nonprofit organizations as well as the governance processes involved are dependent upon the level of integration that is established in the network in terms of the centrality of the leading public agency and the density among the nonprofit actors. We formulate four propositions and distinguish archetypes of governance that guide further research and practice.
A typology of local governments’ engagement with human rights: Legal pluralist contributions to international law and human rights
Authors: Durmuş Elif
Published: April 2020

Local governments around the world have been engaging with international law and policy at an exponential intensity, with prominent engagement in climate change, migration and more recently human rights. This engagement cannot be adequately understood within the terms and framework of positive international law alone. This contribution aims to map and create a grounded typology of local government engagement with human rights, encompassing both activities within their localities and outside - at national, international or transnational scales. The article introduces local governments’ engagement in the Formation of Human Rights, Implementation of Human Rights, Defence of Human Rights, Coordination of Human Rights, Dissemination of Human Rights and the Contestation of Human Rights as empirical ideal types that have emerged from data through grounded theory. Analysing this engagement from the perspectives of both positive international law as well as legal pluralism, with specific focus on the New Haven School of Law, the article argues that local governments are now at the core of a newly formed norm-generating community. Local governments engage with local and international actors and processes both within the rules of inclusion of contemporary international law-making - seeking to expand these norms to include local governments themselves - but they also contest and challenge the very rules of the game in the first place, and resort to creating “human rights in the city” as a body of norms parallel to international human rights law. Whether we accept a pluralist understanding of international law to include local governments and their human rights engagement, or whether we consider these developments to be outside international law, forming a parallel normative order in the legal pluralist sense, local government engagement with human rights has already succeeded in reaching and influencing many established international actors and has already infiltrated recent instruments of positive international law.
Impact of the trailing edge shape of a downstream dummy vehicle on train aerodynamics subjected to crosswind
Authors: Huo Xiaoshuai , Liu Tanghong , Yu Miao , Chen Zhengwei , Guo Zijian , Li Wenhui , Wang Tiantian
Published: April 2020

Wind tunnel tests for trains under large yaw angles are usually limited due to the width of the wind tunnel. Therefore, the leading car and a downstream dummy vehicle model are often employed instead of a real train, but there are no clear regulations regarding the shape of the end of the dummy vehicle. This paper studied the impact of the trailing edge shape of the downstream dummy vehicle on train aerodynamics subjected to crosswind based on the shear-stress-transport k-ω turbulence model of the delayed detached eddy simulation. Three types of end shapes, namely the rectangular end shape, the arc end shape, and the streamlined end shape were chosen for comparison, and the simulation results of the three-car-group train were selected as the benchmark. First, the reliability of the numerical method was validated by wind tunnel tests. Then, the aerodynamic coefficients under yaw angles of 0°–60° and the surface pressure distributions and flow structures around the train under the yaw angle of 60° of the head cars with different end shapes were compared and analyzed.
Simulation of the dynamic retrieval process of a towed target system under towing airplane’s wake and atmospheric turbulence
Authors: Ma Tielin , Wei Zhihua , Chen Haibing , Wang Xiangsheng
Published: April 2020

This paper studies the dynamic retrieval process of a towed target system under perturbation by simulating the reel-in operation under the towing airplane’s wake and atmospheric turbulence. To settle the computational problem of cable tension, the constant-length method is proposed to transform this variable-mass problem into a constant-length problem based on a mass-spring model that discretizes the cable. A three-dimensional atmospheric turbulence field is built using a recursive function to model the complex perturbation field along the cable. A horseshoe vortex model is adopted to simulate the towing airplane’s wake. Simulation analysis shows that both the reel-in speed and turbulence significantly affect the retrieval deviation, whereas the airplane’s wake has little influence. The reel-in speed should be chosen in concert with the turbulence intensity to achieve a high retrieval success rate. Moreover, a higher reel-in speed is preferred to maintain cable strain and smoothen the process when the retrieval tolerance is satisfied.
Interleukin-34 as a marker for subclinical proliferative lupus nephritis
Authors: Abdel-Rehim Asmaa SM , Mohamed Nesrine A , Shakweer Marwa M
Published: April 2020

Background

Lupus nephritis (LN) is an ominous manifestation of systemic lupus erythematosus (SLE). Clinical renal affection is present in about 70% of lupus patients, and more patients have histological evidence of renal involvement without clinical manifestations. This study aimed to investigate the potential role of serum interleukin-34 (IL-34) as an early marker for the detection of silent LN.

Methods

Thirty-three lupus patients with silent LN (group I), 37 patients with clinical LN (group II) and 20 controls were included. The SLE Disease Activity Index (SLEDAI), IL-34, anti-dsDNA antibodies and renal biopsy were assessed in all patients.

Results

Serum IL-34 levels were significantly higher in all lupus patients compared to healthy controls ( p < 0.001) and showed a significant positive correlation with SLEDAI score. SLE patients with positive anti-dsDNA antibodies had more active disease according to SLEDAI and higher levels of IL-34 than those with negative anti-dsDNA antibodies. In both studied groups, serum IL-34 levels were significantly higher in patients with proliferative LN (class III and class IV) than those with non-proliferative lupus (class II and class V) and controls. Yet, in both groups, IL-34 was not useful in differentiating active from chronic renal affection.

Conclusion

In lupus patients with insignificant proteinuria, serum levels of IL-34 distinguished the different histological classes of subclinical LN. Serum IL-34 may be used as a surrogate marker for early renal affection in silent LN, especially the proliferative type.
Measuring the maturity of unopened cotton bolls with near infrared spectroscopy
Authors: Long Robert L , Bange Michael P
Published: April 2020

The boll cutting technique allows cotton producers to gauge the maturity of cotton bolls to help in their decision-making in the final stages of management of their crop leading up to harvest. The aim of this work was to assess the feasibility of using portable near infrared technology as a non-destructive rapid replacement for the manual boll cutting technique. Near infrared spectra (702–1100 nm) were collected from bolls using a Felix F-750 Produce Quality Meter. Spectra were successfully calibrated with two levels of boll maturity (immature and mature) using a partial least squares model for a population of 201 bolls. Independent validation of the model using separate boll populations predicted boll maturity correctly with an average accuracy of 96%. Calibrations that used spectra collected from bolls under field conditions performed similarly to calibrations that used spectra collected from the same bolls under controlled laboratory conditions. There was no preferred spectral sampling location on the bolls that resulted in better calibration performance. Calibration performance did not improve when spectral mathematical pre-treatments were used.
Can Your Neighbour’s Education Affect Your Health?
Authors: Bhattacharjee Ayona , Joshi Radhika
Published: April 2020

Most studies pertaining to the returns to education literature focus on estimating benefits of education that accrue to the individual who spends more years in school. However, from a public policy perspective it is crucial to understand the gains of education to the society at large. This study is an attempt to estimate these social returns to education, that is, the impact of an increase in average education on individual health outcomes. In particular, we try to assess if (above and beyond individual educational attainment), average years of schooling at a district level has an impact on individual health. We obtain individual level data from two rounds of the India Human Development Survey (IHDS) and calculate district level average education using data from the National Sample Survey Organisation (NSSO) surveys for the same years. We use a logit model to estimate the probability of suffering from short-term morbidity and find that there is a strong negative association between short-term morbidity and average education. We also study the impact of average education on health seeking outcomes such as consumption of cigarettes and tobacco. We find that after accounting for individual education and income, the average education at the district level has a strong positive influence on better health seeking behaviour. The results from our study lend support to the notion that in addition to policies aimed at improving healthcare, an increase in average education can potentially lead to improvement in health outcomes.
Between a rock and a hard place: Freedom, flexibility, precarity and vulnerability in the gig economy in Africa
Authors: Anwar Mohammad Amir , Graham Mark
Published: April 2020

The world of work is changing. Communications technologies and digital platforms have enabled some types of work to be delivered from anywhere in the world by anyone with a computer and an internet connection. This digitally-mediated work brings jobs to parts of the world traditionally characterized by low incomes and high unemployment rates. As such, it has been touted by governments, third-sector organizations, and the private sector as a novel strategy of economic development. Drawing on a four-year study with 65 workers in South Africa, Kenya, Nigeria, Ghana and Uganda, we examine the development implications of the gig economy on labour in Africa. We offer four analytical development dimensions through which platform-based remote work impacts the lives and livelihoods of African workers, i.e. freedom, flexibility, precarity and vulnerablity. We argue that these dimensions should be understood in a continuum to better explain the working conditions and lives of workers in the gig economy.
Lessons learned in evaluating the infrastructure of a Centre for Translational Research
Authors: Renger Ralph , Basson Marc D , Hart Gary , Van Eck Rick , Souvannasacd Eric , Renger Jessica , Foltysova Jirina
Published: April 2020

This article shares lessons learned while evaluating the implementation of a Clinical and Translational Research Centre (CTR). To meet its overarching goals, the CTR consists of numerous research support units (e.g., biostatistics, community engagement, professional development) that are intended to work together collaboratively. It is then argued that an evaluation approach grounded in system thinking was the best fit to evaluate this key CTR design feature. The rationale for selecting systems evaluation theory (SET) as the evaluation framework best suited to evaluate the CTR infrastructure is then presented. The application of SET and the lessons learned are then shared. This article concludes that there are many similarly structured programmes worldwide to which the lessons learned can be applied and upfront investments in using a system approach are rewarded by providing meaningful and useful evaluation recommendations for system change.
Aboriginal Family Planning Circle evaluation: Empowering Aboriginal communities in evaluating and future-proofing Aboriginal-led community programmes
Authors: Lawton Amy Elizabeth , Hamilton Olivia , Jackson Cheryl
Published: April 2020

The Aboriginal Family Planning Circle (AFPC) programme is an Aboriginal-led community programme, which works with Aboriginal families in Western Sydney to address their complex needs and reduce the risk of having their children put into out-of-home care (OOHC). This article explores two external evaluations undertaken by WESTIR Limited (WESTIR), a non-Aboriginal research service, on the AFPC programme. The purpose of the first evaluation was to provide an assessment of how effective the AFPC programme had been for participants and identify programme aspects that could be improved or developed. The second evaluation was undertaken to examine whether the AFPC programme had continued to meet its objectives and address some knowledge gaps, particularly the estimated savings and return on investment that the programme created for the OOHC system in New South Wales (NSW). The evaluations used qualitative and quantitative techniques, including interviews, focus groups and a return on investment analysis. This article outlines methods, results and recommendations from both evaluations, along with lessons learned to better inform evaluation practice. This case study shows that culturally responsive evaluations can provide an avenue for Aboriginal communities to advocate for the continued funding of their programmes. It also emphasises the need to adequately resource Aboriginal programme evaluations in the community services sector now and in the future.
“I Look at You and See You Looking at Me”: Role Boundaries in a Dynamic Research Relationship in Qualitative Health Research With Refugees
Authors: de Smet Sofie , Rousseau Cécile , Stalpaert Christel , De Haene Lucia
Published: April 2020

In institutional ethical and deontological guidelines, there is a prevailing, static understanding of the research partnership, with a clear boundary between researcher and participant. In this article, we argue that such a static understanding may run the risk of impeding the development of an enhanced contextual and dynamic intersubjective understanding of the research partnership and its impact on the growing importance of role boundaries in qualitative research. Drawing from a refugee health study on trauma and forced migration, we explore the different ways in which participants and the researcher engaged with the researcher’s multiple positions and role boundaries. In doing so, we aim to contribute to a reflective research practice by providing tools to recognize signs of potential harm and offer potential vehicles of reconstruction and agency within the intersubjective space of a dynamic research relationship, within a continuous, shared renegotiation process of role boundaries.
Lexical Selectivity of 2-Year-Old Children With and Without Repaired Cleft Palate Based on Parent Report
Authors: Baylis Adriane , Vallino Linda D. , Powell Juliana , Zajac David J.
Published: April 2020

Objective:

To determine vocabulary and lexical selectivity characteristics of children with and without repaired cleft palate at 24 months of age, based on parent report.

Participants:

Forty-nine children with repaired cleft palate, with or without cleft lip (CP±L; 25 males; 21 cleft lip and palate, 28 CP only), 29 children with a history of otitis media (OM) and ventilation tubes (21 males), and 25 typically developing (TD) children (13 males).

Main Outcome Measure(s):

Parent-reported expressive vocabulary was determined using the MacArthur Communicative Development Inventory: Words and Sentences.

Results:

Vocabulary size was reduced for children with repaired CP±L compared to children in the TD group ( P = .025) but not the OM group ( P = .403). Mean percentage of words beginning with sonorants did not differ across groups ( P = .383). Vocabulary size predicted sonorant use for all groups ( P = .001).

Conclusions:

Children with repaired CP±L exhibit similar lexical selectivity relative to word initial sounds compared to noncleft TD and OM peers at 24 months of age, based on parent report.
Desmoplastic Small Round Cell Tumor of Parotid Gland: A Rare Entity With Diagnostic Challenge
Authors: Cai Zhenjian , Zhang Lin , Karni Ron J. , Saluja Karan , Liu Jing , Zhu Hui
Published: April 2020

Desmoplastic small round cell tumor (DSRCT) is a rare malignant mesenchymal neoplasm that typically affects young patients and presents as large intraabdominal masses. We report a rare case of parotid gland DSRCT in a 38-year-old man. The tumor cells were large sized and form irregular nests embedded in abundant desmoplastic stroma. Immunohistochemically, the tumor cells were positive for cytokeratin, GATA3, p40, and p63. Working differential diagnosis included squamous cell carcinoma, myoepithelial carcinoma, hyalinizing clear cell carcinoma, NUT (nuclear protein of the testis) carcinoma, and adamantinoma-like Ewing sarcoma. The characteristic morphologic features and presence of EWSR1-WT1 gene fusion are diagnostic of DSRCT. Salivary gland DSRCT is an exceedingly rare entity, with only 6 cases reported in the literature.
Pushing Boundaries: How Coding Is (and Isn’t) Taught in Accredited Journalism Programs
Authors: Foust James C. , Bradshaw Katherine A.
Published: April 2020

A census of Accrediting Council on Education in Journalism and Mass Communications (ACEJMC)–accredited journalism programs reveals that less than a quarter require students to learn code. Despite industry desires for journalists with coding skills, nearly 40% of the units offer no coding classes. Among programs that require code, most rely on a course or courses taught by full-time faculty in the accredited unit. About one third of units that do not require code currently have plans to add it in the future.
Adult-Onset Atopic Dermatitis: Presentations and Progress
Authors: Chan Airiss R. , Sandhu Vijay K. , Drucker Aaron M. , Fleming Patrick , Lynde Charles W.
Published: April 2020

Atopic dermatitis (AD) is a chronic skin disease characterized by barrier dysfunction and immune dysregulation that affects approximately 20% of children and 2-5% of adults worldwide. Traditionally, AD has been considered a disease of childhood with many cases resolving before adulthood. However, in recent years, the prevalence of adult AD is increasingly recognized to be substantial, but it is uncertain whether this increase is due to increased childhood-persistent or relapsed AD, or new adult-onset AD. This highlights a need for further investigation into the adult AD population and evaluation of phenotypes in the adult-onset cohort. In this literature review, we examine five studies focused on adult-onset AD phenotype, conducted between 2013 and 2017. The most commonly reported body regions affected in adult-onset AD were the hands, eyelids, neck, and flexural surfaces of the upper limbs. These vary from childhood-onset AD findings, which are less specific to body regions other than flexural areas. These findings have implications for diagnostic accuracy and treatment of AD, including considerations for therapeutic choices and inclusion and exclusion criteria in clinical trials.
Inferring party positions across issue dimensions
Authors: Liñeira Robert , Muñoz Jordi , Rico Guillem
Published: April 2020

In this article, we argue that voters use party positions on an issue dimension as a heuristic device to locate parties on other dimensions on which they have less information about. We confirm our argument by fielding two survey experiments in a context with two distinct issue dimensions: the left-right and national dimensions in Catalonia. We find that the position of a hypothetical (but plausible) candidate on a national dimension exerts a great deal of influence on where respondents locate him on the left-right dimension, as well as on a more narrowly-defined socioeconomic dimension, but that the left-right position does not affect the perceived placement on the national divide. This asymmetry can be partly explained by the different nature of these issue domains, and specifically by the distinct ability of the national dimension to activate social group cues that give rise to projection biases. These findings have important implications for our understanding of issue misperceptions and of the strategic choices available to parties in multidimensional policy spaces. The nature of the issue dimension could facilitate why some issue dimensions tend to function as cue givers and others as cue receivers. We discuss the implications of our findings in constraining the strategies available to parties in multidimensional contexts.
Using a systematic review to uncover theory and outcomes for a complex intervention in health and social care: a worked example using life story work for people with dementia
Authors: Parker Gillian , Gridley Kate , Birks Yvonne , Glanville Julie
Published: April 2020

Objectives

Life story work involves gathering information about a person, their history and interests, and producing a tangible output, usually a book. It is used increasingly in dementia care. However, theory about if, how, and why it affects outcomes is poorly developed, making the choice of evaluation methods and appropriate outcomes difficult. This article uses a systematic review to uncover theories of change and outcomes for life story work in dementia care. We describe the methods and their use in identifying appropriate outcomes for evaluative research, and their potential for improving evaluation of ‘theory poor’ interventions.

Methods

A systematic review, carried out using Centre for Reviews and Dissemination guidelines, searched for evidence on underlying theory, good practice, and effectiveness of life story work to inform a feasibility study for the formal evaluation of life story work in dementia care. For the theory element, a ‘landscaping review’ analysed the extracted text, using qualitative techniques and mind maps to uncover both explicit and implicit causal links between life story work and outcomes. We triangulated the review findings with qualitative research, which used focus groups with people with dementia, caregivers, and professionals that explored the outcomes that they would like to see from life story work.

Results

Of the 56 publications reviewed, only 16 were useful for the theory analysis. Six overarching outcomes were identified: the self-worth and empowerment of people with dementia, individual psychological outcomes, improved relationships between care staff and the individual with dementia, better care, more effective engagement of family members/carers within the care setting, and helping carers to cope. Twelve final theories linking these outcomes to life story work via a causal pathway were elicited. There was substantial overlap in the outcomes identified by the review and by carers, people with dementia, and professionals. Together, the results informed our choice of outcome measures for the pilot evaluation.

Conclusions

This approach may enable researchers to identify and develop the theory necessary before evaluation of a complex intervention in other under- or un-theorized areas. It has the potential both to shorten development stages (and thereby costs) in intervention research and improve the intervention itself.
The impact of photographs on the online marketing for tourism: The case of Japanese-style inns
Authors: Jimura Takamitsu , Lee Timothy J
Published: April 2020

This article examines the impact of the use of photographs in online marketing for tourism through a case study based on Japanese-style inns. Nowadays, most Japanese-style inns present photographs of what they think are their key appealing elements on their own social networking and/or video/photo-sharing websites, while guests upload their photographs and write comments on travel or social networking websites and/or on the websites of e-travel agents. Through the medium of ‘netnography’, this research has identified that the photographs presented online by Japanese-style inns can affect decision-making processes of guests and/or expectations in both a positive and a negative way, and e-word of mouth can work together with the photographs to influence prospective guests.
Differential relationships of somatization, depression, and anxiety to severity of Crohn’s disease

Published: April 2020

Patients with Crohn’s disease, an inflammatory bowel disease, struggle with chronic somatic symptoms that could bring about emotional distress. This study assessed the relative role of somatization, and depressive and anxiety symptoms in disease activity among 619 Crohn’s patients (18–79 years; 58.3% women). Structural equation modeling revealed that somatization was the only unique predictor of disease activity beyond depression and anxiety. In addition, the effect of somatization on disease activity was stronger in men compared to women. Findings suggest that somatization represents a distinct domain of psychological distress that may play a role in the health of patients with Crohn’s disease.
Beyond Social Mobility: Biographies, Habitus and Responses to Changing ‘Conditions of Existence’ among University Scholarship Students
Authors: Nimer Maissam
Published: April 2020

Wider access to higher education at a global level has been accompanied by growing literature on experiences of social mobility often using the concept of habitus as a theoretical tool to frame responses to changes in ‘conditions of existence’. Drawing on the case study of a scholarship programme within an elite university in Lebanon, through in-depth interviews with students and university faculty and staff, this article elaborates on the typologies in responses that emerged as students position themselves in a new environment. These typologies, in contrast to the literature which presents them as a result of alterations in the habitus, appear to be related to each other and occur simultaneously within one person’s trajectory. As such, instead of viewing these responses as degrees of incorporation of each set of schemes of perceptions from both fields, the context of origin and the new social context appear to be multi-faceted, and the interaction between them is complex. I argue, along the lines of Lahire’s dispositional perspective, that the situation of contradictory experiences is not exceptional but characterizes all individuals to a certain extent, especially in the Lebanese context which is distinguished by its diversity in terms of regional and religious affiliations and in which class intersects with other types of identifications.
Active vibration reduction system with mass damper tuned using the sliding mode control algorithm
Authors: Snamina Jacek , Orkisz Paweł
Published: April 2020

The paper aims at evaluating the sliding mode control parameters used to tune a dynamic damper in the vibration reduction system. The effectiveness of the presented vibration reduction system and the power of the controlled voltage source supplying an electrodynamic linear motor have been analysed. The classical sliding mode control algorithm has been modified based on the analyses of results of calculation. The operation of the modified algorithm has been checked during a simulation. The proposed vibration reduction system was implemented on a laboratory stand. The measurement results have confirmed the effectiveness of the considered system.
Performing populism: Trump’s transgressive debate style and the dynamics of Twitter response
Authors: Bucy Erik P , Foley Jordan M , Lukito Josephine , Doroshenko Larissa , Shah Dhavan V , Pevehouse Jon CW , Wells Chris
Published: April 2020

Populism, as many have observed, is a communication phenomenon as much as a coherent ideology whose mass appeal stems from the fiery articulation of core positions, notably hostility toward “others,” bias against elites in favor of “the people,” and the transgressive delivery of those messages. Yet much of what we know about populist communication is based on analysis of candidate pronouncements, the verbal message conveyed at political events and over social media, rather than transgressive performances—the visual and tonal markers of outrage—that give populism its distinctive flair. The present study addresses this gap in the literature by using detailed verbal, tonal, and nonverbal coding of the first US presidential debate of 2016 between Donald Trump and Hillary Clinton to show how Trump’s transgressive style—his violation of normative boundaries, particularly those related to protocol and politeness, and open displays of frustration and anger—can be operationalized from a communication standpoint and used in statistical modeling to predict the volume of Twitter response to both candidates during the debate. Our findings support the view that Trump’s norm-violating transgressive style, a type of political performance, resonated with viewers significantly more than Clinton’s more controlled approach and garnered Trump substantial second-screen attention.
Twitter and Facebook: Populists’ double-barreled gun?
Authors: Jacobs Kristof , Sandberg Linn , Spierings Niels
Published: April 2020

Social media are said to be a core driver of populists’ current success. Yet, our knowledge of how populist politicians use social media is limited. We argue that they can use Twitter and Facebook, politically the most important platforms, as a “double-barreled gun,” each serving a different target. Based on the architecture of the platforms and the populist ideology, we expect that Twitter is used to name and shame journalists publicly, Facebook to activate anger among citizens. Both types of use are examined by studying the Members of Parliament (MPs) of Austria, The Netherlands, and Sweden. We collected 9852 tweets for the 475 MPs on Twitter and 10,355 Facebook posts from the 287 MPs with a Facebook Page. Using negative binomial regression and content analyses, we find that populists seem eager to activate anger. They are not more likely to @-mention media accounts, but “shame” them roughly three times more often.
Public opinion and the death penalty in Japan
Authors: Andreescu Viviana , Hughes Tom “Tad”
Published: April 2020

Based on the Japanese General Social Survey conducted in 2010 on a representative sample of adults, the present analysis intends to identify the factors more likely to predict variations in death penalty attitudes in Japan. Compared to death penalty proponents, those who oppose capital punishment are less likely to express punitive attitudes in general and to be dissatisfied with government expenditures on crime control. Relative to retentionists, abolitionists tend to have a higher level of social trust, show a higher level of support for public participation in the criminal justice process, are more likely to practice a religion, and are younger. Instrumental factors, such as victimization and fear of crime, symbolic factors, such as institutional trust, trust in the judiciary, and the police, as well as gender do not differentiate death penalty opponents from supporters. The results of the multinomial logistic regression show that residents who did not express agreement or disagreement with the death penalty have more in common with those who oppose capital punishment than with those who favor it. Although the majority of the population (65.2%) expressed support for death penalty, one in four respondents (26.1%) remained ambivalent regarding the use of capital punishment. Additionally, most of those who expressed an opinion (50.5%) said they would hesitate to recommend death, if chosen to serve in the newly instituted citizen judge system. Findings suggest that public support for death penalty is not as strong in the country as the Japanese government claims and that it requires further exploration.
Factors affecting the intention to adopt light-emitting diode lighting at home

This study investigates the significant factors affecting the adoption of light emitting diode lighting among households in Malaysia by conceptualizing and extending the unified theory of acceptance and use of technology through the adaptation of price value and the anticipated emotions of pride and guilt within the model. This study used the partial least squares technique to validate measurements and to test the research hypotheses. The results obtained from analysing 1075 valid survey questionnaires revealed the effects of performance expectancy, effort expectancy and price value on the intention to use light-emitting diodes among Malaysian households. While the results support the mediating role of attitude between the three variables and intention to use light-emitting diodes, the moderating role of anticipated pride on the relationship between attitude and intention to use light-emitting diodes was not supported. The findings confirm that guilt significantly moderates the relationship between attitude and intention.
Houston, We Have a Problem: Enhancing Academic Freedom and Transparency in Publishing Through Post-Publication Debate
Authors: Gleditsch Kristian Skrede
Published: April 2020

Debates over controversial articles often highlight important issues regarding academic freedom, transparency, and how to handle disagreements in publishing. I argue that a response outlining criticism is generally a more productive course of action than calling for retraction. However, there are a number of constraints that impede meaningful debates, and a problematic divergence between our common ideals of open research and free debate and the actual practices that we see in academic publishing, where our current practices often undermine transparency, replication, and scientific debate. I argue that research can benefit from more explicit recognition of politics and preferences in how we evaluate research as well greater opportunities for post-publication debate. The successful initiatives to promote data replicability over the past decade provide useful lessons for what improved post-publication transparency may look like.
Violence Exposure and Mental Health Among Resettled Refugees: A Systematic Review
Authors: Scoglio Arielle A. J. , Salhi Carmel
Published: April 2020

Refugee populations are often characterized by their high exposure to violence, which are tied to various challenges upon resettlement. This systematic review synthesizes the empirical literature related to violence exposure for refugees resettled in high-income countries and the impact of that exposure on mental health symptoms. The authors reviewed quantitative studies published from 2000 to 2018 and found 12 studies met criteria for inclusion. Studies were excluded if the study did not include a measured mental health outcome, if violence exposure was not measured and reported on distinctly from nonviolent exposures, if the sample did not include a refugee population, or if the relationship between violence exposure and mental health of refugees was not empirically examined. Overall, studies found that resettled refugee populations were more likely to have higher rates of violence exposure than comparison groups. This violence exposure was significantly related to higher mental health symptoms, including symptoms of depression, anxiety, and, most commonly reported, posttraumatic stress disorder. However, there is substantial heterogeneity in measurement of violence exposure, particularly in the use of author-created scales. The vast majority of included studies examined only exposure to violence prior to resettlement. The review shows significant evidence for the effect of violence prior to resettlement on mental health after resettlement and reveals a need for improved measurement and definitions of violence exposure at different time points for resettled refugee populations. Assessing current exposure to violence is an important step for effective intervention related to mental health dilemmas for refugee populations.
A Meta-Analysis on Effects of Parenting Programs on Bullying Prevention
Authors: Chen Qiqi , Zhu Yuhong , Chui Wing Hong
Published: April 2020

Bullying is a serious public health concern across the globe. While there are a number of bullying interventions with parental components, limited efforts have been made to synthesize the impacts of parenting programs on bullying prevention. This meta-analysis aimed to review and examine parenting programs on bullying reduction that involving both school-based and home visiting anti-bullying programs. The overall effect size supported a significant outcome on bullying reduction ( d = .640, 95% confidence interval [CI] [0.239, 1.041]). Results of this meta-analysis reported that participants in the parenting programs scored significantly lower on both bullying and victimization. Data from the randomized controlled trials and the pre- and posttest design studies showed evidence of highly significant effects of parenting interventions on bullying reduction. Child- and parent-related factors including parenting style, children’s empathy, and parent–child interaction about bullying were found to be significantly related to the effectiveness of intervention programs. This study provides evidence to enhance policy and practice for effectively enabling parent involvement in bullying behavior reduction and to increase parent–children communication about bullying as well as parenting skills. Future researchers and practitioners may explore more about the impact of school–family partnerships and their reliance on each other to help reduce bullying.
Youth Internet Safety Education: Aligning Programs With the Evidence Base
Authors: Finkelhor David , Walsh Kerryann , Jones Lisa , Mitchell Kimberly , Collier Anne
Published: April 2020

Background:

This review critically examines the messages of youth internet safety education programs in the light of research about both the dynamics of internet dangers and the efficacy of youth prevention education.

Methods:

Using terms “internet safety education” and “digital citizenship,” a Google search identified 12 multi-topic safety programs. Review articles were identified via Google Scholar for six forms of online harm to youth that have been targeted by many of these programs: cyberbullying (19 articles); online sexual exploitation (23 articles); sexting (19 articles); online fraud, hacking, and identity theft (6 articles); online suicide and self-harm promotion (18 articles); and internet overuse or addiction (15 articles).

Findings:

There appear to be mismatches between dynamics revealed in the research about internet harms and the messages emphasized in educational programs, particularly on the issues of sexual exploitation and sexting. Overall, the review literature also suggests major advantages to integrating internet safety into already well-established and evidence-based programs currently addressing related off-line harms, for example, programs focusing on general bullying, dating abuse, or sexual abuse prevention. The advantages stem from four factors: (1) the considerable overlap between online harms and similar off-line harms, (2) the apparent greater prevalence of off-line harms, (3) the evidence that the same risk factors lie behind both online and off-line harms, and most importantly, (4) the substantially superior evidence base for the longer standing programs developed originally around the off-line harms.
