Published: June 2020

As bariatric surgery increases, there is a growing population of patients with biliary obstruction and anatomy which precludes transoral access through endoscopic retrograde cholangiopancreatography (ERCP). Minimally invasive transgastric ERCP (TG-ERCP) offers a feasible alternative for the treatment. A retrospective review was performed of all patients who underwent laparoscopic or robotic-assisted TG-ERCP between 2010 and 2017. Chart abstraction collected demographics, procedural details, success rate, and postoperative outcomes. Forty patients were identified, of which 38 cases were performed laparoscopically and two robotically. Median operative time was 163 minutes, with an estimated blood loss of 50 cc. TG-ERCP was performed successfully in 36 cases (90%); sphincterotomy was completed in 35 patients (97%). Sixty per cent already had a cholecystectomy; in the remaining patients, it was performed concurrently. Major complications included stomach perforation (n = 1), pancreatitis (n = 3), and anemia requiring transfusion (n = 2). In patients with biliary obstruction and anatomy not suitable for ERCP, TG-ERCP can be performed in a minimally invasive fashion, with a high rate of technical success and low morbidity. We describe a stepwise, reproducible technique because it is an essential tool for the shared armamentarium of endoscopists and surgeons.
A randomised trial of dialectical behaviour therapy and the conversational model for the treatment of borderline personality disorder with recent suicidal and/or non-suicidal self-injury: An effectiveness study in an Australian public mental health service
Authors: Walton Carla J , Bendit Nick , Baker Amanda L , Carter Gregory L , Lewin Terry J
Published: June 2020

Objectives:

Borderline personality disorder is a complex mental disorder that is associated with a high degree of suffering for the individual. Dialectical behaviour therapy has been studied in the largest number of controlled trials for treatment of individuals with borderline personality disorder. The conversational model is a psychodynamic treatment also developed specifically for treatment of borderline personality disorder. We report on the outcomes of a randomised trial comparing dialectical behaviour therapy and conversational model for treatment of borderline personality disorder in a routine clinical setting.

Method:

Participants had a diagnosis of borderline personality disorder and a minimum of three suicidal and/or non-suicidal self-injurious episodes in the previous 12 months. Consenting individuals were randomised to either dialectical behaviour therapy or conversational model and contracted for 14 months of treatment ( n = 162 commenced therapy). Dialectical behaviour therapy involved participants attending weekly individual therapy, weekly group skills training and having access to after-hours phone coaching. Conversational model involved twice weekly individual therapy. Assessments occurred at baseline, mid-treatment (7 months) and post-treatment (14 months). Assessments were conducted by a research assistant blind to treatment condition. Primary outcomes were change in suicidal and non-suicidal self-injurious episodes and severity of depression. We hypothesised that dialectical behaviour therapy would be more effective in reducing suicidal and non-suicidal self-injurious behaviour and that conversational model would be more effective in reducing depression.

Results:

Both treatments showed significant improvement over time across the 14 months duration of therapy in suicidal and non-suicidal self-injury and depression scores. There were no significant differences between treatment models in reduction of suicidal and non-suicidal self-injury. However, dialectical behaviour therapy was associated with significantly greater reductions in depression scores compared to conversational model.

Conclusion:

This research adds to the accumulating body of knowledge of psychotherapeutic treatment of borderline personality disorder and supports the use of both dialectical behaviour therapy and conversational model as effective treatments in routine clinical settings, with some additional benefits for dialectical behaviour therapy for persons with co-morbid depression.
Influence of College Students’ Agreeableness on Interpersonal Relationships: Moderating Role of Empathy
Authors: Yang Dong , Tu Chia-Ching
Published: June 2020

This study explored the moderating influence of empathy on agreeableness in interpersonal relationships among Chinese college students. Surveys and tests were conducted among a representative sample of 834 college students from four universities in Yunnan, China. Structural equation models were used to test causality and moderation. Support was found for a model that identified agreeableness and empathy as valid predictors of interpersonal relationships and empathy as a moderating influence between agreeableness and interpersonal relationships. These results suggest that the growth of interpersonal relationships for agreeable students is suppressed by higher levels of empathy. In addition, lower levels of empathy may promote the growth of interpersonal relationships for agreeable students. The results suggest that enhancing empathy is not always applicable to all groups of individuals and that training methods aimed at reducing empathy may be used to ameliorate bad interpersonal relationship in students with agreeable personality traits.
Does context matter? A cross-country investigation of the effects of the media context on external and internal political efficacy
Authors: Bene Marton
Published: June 2020

As a motivational factor of action, political efficacy is an important predictor of political behavior. The term was invented to capture the extent to which people feel that they can effectively participate in politics and shape political processes. Today, we have a comprehensive knowledge of the individual-level factors (socio-demographic variables, political preferences, etc.) that shape the level of internal and external dimensions of political efficacy. However, while it is widely demonstrated that media consumption influences the level of political efficacy, the country-level media context factors affecting it have rarely been studied. This article reports the findings of extensive research on how two crucial features of the media context, the political significance of the media and the level of political parallelism in the media system, shape the level of external and internal political efficacy. The investigation draws upon the data set of the seventh round (2014–2015) of the European Social Survey (ESS) and includes more than 22,000 respondents from 19 European democracies. The research hypothesizes that in countries where the media play a more important role, people have lower levels of external and higher levels of internal political efficacy. Political parallelism, which shows the extent to which media outlets are driven by distinct political orientations and interests within a particular media system, is expected to directly increase both external and internal political efficacy. Its indirect effect is also hypothesized, arguing that partisan media amplifies the winner–loser gap in political efficacy as a kind of “echo chamber.” The findings show that in countries where the media play a major role in shaping political discourse, people have lower levels of external political efficacy, while the political parallelism of the media system indirectly affects the external dimensions of political efficacy. Internal political efficacy is, however, not related to these context-level factors.
Interplay of fabric structure and shear thickening fluid impregnation in moderating the impact response of high-performance woven fabrics
Authors: Arora Sanchi , Majumdar Abhijit , Singh Butola Bhupendra
Published: June 2020

The beneficial effect of STF impregnation in enhancing the impact resistance of high-performance fabrics has been extensively reported in the literature. However, this research work reports that fabric structure has a decisive role in moderating the effectiveness of STF impregnation in terms of impact energy absorption. Plain woven fabrics having sett varying from 25 × 25 inch−1 to 55 × 55 inch−1 were impregnated with STF at two different padding pressures to obtain different add-ons. The impact energy absorption by STF impregnated loosely woven fabrics was found to be higher than that of their neat counterparts for both levels of add-on, while opposite trend was observed in case of tightly woven fabrics. Further, comparison of tightly woven plain, 2/2 twill, 3/1 twill and 2 × 2 matt fabrics revealed beneficial effect of STF impregnation, except for the plain woven fabric, establishing that there exists a fabric structure-STF impregnation interplay that tunes the impact resistance of woven fabrics.
Measuring risk of missing transfers in public transit systems using high-resolution schedule and real-time bus location data
Authors: Liu Luyu , Miller Harvey J
Published: June 2020

The emergence of urban Big Data creates new opportunities for a deeper understanding of transportation within cities, revealing patterns and dynamics that were previously hidden. Public transit agencies are collecting and publishing high-resolution schedule and real-time vehicle location data to help users schedule trips and navigate the system. We can use these data to generate new insights into public transit delays, a major source of user dissatisfaction. Leveraging open General Transit Feed Specification (GTFS) and administrative Automatic Passenger Counter (APC) data, we develop two measures to assess the risk of missing bus route transfers and the consequent time penalties due to delays. Risk of Missing Transfers (RoMT) measures the empirical probability of missed transfers, and Average Total Time Penalty (ATTP) shows overall time loss compared to the schedule. We apply these measures to data from the Central Ohio Transit Authority (COTA), a public transit agency serving the Columbus, Ohio, USA metropolitan area. We aggregate, visualise and analyse these measures at different spatial and temporal resolutions, revealing patterns that demonstrate the heterogeneous impacts of bus delays. We also simulate the impacts of dedicated bus lanes reducing missing risk and time penalties. Results demonstrate the effectiveness of measures based on high-resolution schedule and real-time vehicle location data to assess the impacts of delays and to guide planning and decision making that can improve on-time performance.
New municipalism in action or urban neoliberalisation reloaded? An analysis of governance change, stability and path dependence in Madrid (2015–2019)
Authors: Janoschka Michael , Mota Fabiola
Published: June 2020

Local politics in Spain has triggered iconic shifts over the last few years, and the electoral success of new ‘movement parties’ in particular has dramatically challenged the political establishment. Between 2015 and 2019, many municipalities – including, crucially, the two biggest cities, Madrid and Barcelona – were governed by coalitions originating from anti-austerity, anti-eviction and pro-democracy struggles. This has significantly affected hegemonic and widely normalised discourses supporting the neoliberalisation of urban politics, and to some extent has also prompted novel governance approaches. Based on empirical research undertaken with local councillors, officials, consultants and activists, the article develops an in-depth analysis of governance transformations in the Spanish capital of Madrid. By doing so, it evaluates the ambiguities and contradictions that the government coalition Ahora Madrid was facing during the 2015–2019 legislative term. The debate stimulates critical reflections for academics, practitioners and movements on the transformative capacities that new municipalisms may enact, as well as the constraints faced by established multi-level urban governance regimes.
Effects of Monetary Incentives on Teacher Turnover: A Longitudinal Analysis
Authors: Ryu Sangyub , Jinnai Yusuke
Published: June 2020

Teacher turnover has been reported as a strong predictor for students’ academic achievement, yet little is known about the determinants of teacher turnover. Using a fixed effects model, we analyze panel data of individual teachers in North Carolina schools to test the effects of monetary incentives on teacher turnover. We find a U-shaped relationship between teacher salary and turnover, while the effects of group-based merit pay on turnover depend on salary level. Assuming that a teacher’s salary reflects their qualifications, the current study concludes that overqualified and underqualified teachers are likely to leave and that group-based merit pay causes turnover among qualified teachers.
Identifying and developing desirable soft skills for public service
Authors: Kinsella Chad , Waite Brandon
Published: June 2020

One of the key goals of any academic program is to ensure that skills taught in the classroom apply to post-graduate employment. Failure to do so can impact an academic department’s recruitment and retention efforts, strain relations with alumni and damage the institution’s reputation. Using interviews conducted during a faculty externship at a high-performing municipal government, this paper identifies soft skills employers expect students to have when entering the public-sector workforce, and offers suggestions for how to best prepare students for public-sector employment in light of these findings.
Identifying High-risk Areas of Foot-and-mouth Disease Outbreak Using a Spatiotemporal Score Statistic: A Case of South Korea
Authors: Pak Son-Il , Lee Gyoungju , Sin Munsu , Park Hyuk , Park JiYoung
Published: June 2020

The objective of this study is to identify high-risk areas of foot-and-mouth disease (FMD) in South Korea using nationwide data collected for the disease cases that occurred during the period from December 2014 to April 2015. High-risk areas of FMD occurrence are defined as local clusters or hot spots, where the frequency of disease occurrence is higher than expected. An issue in the FMD detection study is in identifying a spatial pattern deviated significantly from the expected value under the null hypothesis that no spatial process is investigated. While identifying geographic clusters is challenging to reveal the causes of disease outbreak, it is most useful to detect and monitor potential areas of risk occurrence and suggest a further in-depth investigation. This study extended a traditional score statistic (SC) that has limited to identify the spatial pattern by proposing a spatiotemporal score statistic (STSC) that incorporates a temporal component into the SC approach. STSC, a local spatial statistic, was utilized to detect clusters around the known foci with a latent period. This study demonstrated STSC could better exploit the advantage of the original SC and improve the cluster detection due to the latent time component. The empirical results of STSC are expected to provide more useful policy implications with agencies in charge of preventing and controlling the spread of epidemics when deciding where to concentrate the limited resources available.

Published: June 2020

Breast cancer ranks first among cancers affecting women’s health. Our work aims to realize the intelligence of the medical ultrasound equipment with limited computational capability, which is used for the assistant detection of breast lesions. We embed the high-computational deep learning algorithm into the medical ultrasound equipment with limited computational capability by two techniques: (1) lightweight neural network: considering the limited computational capability of ultrasound equipment, a lightweight neural network is designed, which greatly reduces the amount of calculation. And we use the technique of knowledge distillation to train the low-precision network helped with the high-precision network; (2) asynchronous calculations: consider four frames of ultrasound images as a group; the image of the first frame of each group is used as the input of the network, and the result is respectively fused with the images of the fourth to seventh frames. An amount of computation of 30 GFLO/frame is required for the proposed lightweight neural network, about 1/6 of that of the large high-precision network. After trained from scratch using the knowledge distillation technique, the detection performance of the lightweight neural network (sensitivity = 89.25%, specificity = 96.33%, the average precision [AP] = 0.85) is close to that of the high-precision network (sensitivity = 98.3%, specificity = 88.33%, AP = 0.91). By asynchronous calculation, we achieve real-time automatic detection of 24 fps (frames per second) on the ultrasound equipment. Our work proposes a method to realize the intelligence of the low-computation-power ultrasonic equipment, and successfully achieves the real-time assistant detection of breast lesions. The significance of the study is as follows: (1) The proposed method is of practical significance in assisting doctors to detect breast lesions; (2) our method provides some practical and theoretical support for the development and engineering of intelligent equipment based on artificial intelligence algorithms.

Authors: Steinmetz Carolin , Bjarnason-Wehrens Birna , Baumgarten Heike , Walther Thomas , Mengden Thomas , Walther Claudia
Published: June 2020

Objective:

To determine the impact of an exercise-based prehabilitation (EBPrehab) program on pre- and postoperative exercise capacity, functional capacity (FC) and quality of life (QoL) in patients awaiting elective coronary artery bypass graft surgery (CABG).

Design:

A two-group randomized controlled trail.

Setting:

Ambulatory prehabilitation.

Subjects:

Overall 230 preoperative elective CABG-surgery patients were randomly assigned to an intervention (IG, n = 88; n = 27 withdrew after randomization) or control group (CG, n = 115).

Intervention:

IG: two-week EBPrehab including supervised aerobic exercise. CG: usual care.

Main measures:

At baseline (T1), one day before surgery (T2), at the beginning (T3) and at the end of cardiac rehabilitation (T4) the following measurements were performed: cardiopulmonary exercise test, six-minute walk test (6MWT), Timed-Up-and-Go Test (TUG) and QoL (MacNew questionnaire).

Results:

A total of 171 patients (IG, n = 81; CG, n = 90) completed the study. During EBPrehab no complications occurred. Preoperatively FC (6MWTIG: 443.0 ± 80.1 m to 493.5 ± 75.5 m, P = 0.003; TUGIG: 6.9 ± 2.0 s to 6.1 ± 1.8 s, P = 0.018) and QoL (IG: 5.1 ± 0.9 to 5.4 ± 0.9, P < 0.001) improved signiﬁcantly more in IG compared to CG. Similar effects were observed postoperatively in FC (6MWDIG: Δ-64.7 m, pT1–T3 = 0.013; Δ+47.2 m, pT1–T4 < 0.001; TUGIG: Δ+1.4 s, pT1–T3 = 0.003).

Conclusions:

A short-term EBPrehab is effective to improve perioperative FC and preoperative QoL in patients with stable coronary artery disease awaiting CABG-surgery.

Published: June 2020

Amyloidosis is classified according to the amyloid precursor protein, and accurate diagnosis of the amyloidosis type may guide appropriate treatment. Immunohistochemistry and Congo red staining are the most frequently used methods used to distinguish types of amyloidosis, but problems with specificity and sensitivity indicate the need for an alternative diagnostic method. In this study, we evaluated laser microdissection-liquid chromatography-tandem mass spectrometry (LMD-LC-MS/MS) for the diagnosis of amyloid light-chain (AL) amyloidosis in animals. Plasmacytomas with amyloid deposits from 15 dogs and 2 cats were subjected to Congo red staining with or without potassium permanganate pretreatment, immunohistochemistry for kappa and lambda light chains, and LMD-LC-MS/MS. Congo red staining was diagnostic in 12 of 17 cases based on resistance to potassium permanganate pretreatment, but in 5 of 17 cases the pretreatment unexpectedly reduced Congo red staining or abrogated the birefringence and a definitive diagnosis could not be reached. Immunohistochemistry detected kappa or lambda light chains in 6 of 17 cases. With LMD-LC-MS/MS, immunoglobulin lambda light chain was detected in all 17 cases. The amyloid signature proteins ApoA-I, ApoA-IV, and ApoE were detected in 9, 1, and 3 of the 15 canine cases by LMD-LC-MS/MS, but not in the feline cases. In conclusion, LMD-LC-MS/MS consistently determined the amyloid type in all examined specimens, while Congo red staining after potassium permanganate treatment and immunohistochemistry were less sensitive tests.

Published: June 2020

Background

Sparse evidence has detailed the clinical phenotype of migraine presenting as isolated facial pain. Objective and methods: This was a prospective audit, part of our multidisciplinary facial pain service evaluation, aiming to phenotype patients with migraine presenting as isolated facial pain who attended our service between 2013 and 2018.

Results

Fifty-eight patients were diagnosed with migraine with isolated facial pain (F = 46, 79.3%; mean age: 49.0 years, ± 9.85). Sixty-six percent of patients met the criteria for episodic migraine. The pain was strictly unilateral in 79% and located over the maxillary region in 85% of patients. Associated cranial autonomic signs/symptoms were reported by 45% of our cohort. A percentage of 77% of patients was triptan responders.

Conclusions

Migraine presenting as isolated facial pain is a rare but treatable condition with some distinct demographic and clinical characteristics. It is a diagnosis of exclusion that should be evaluated in specialised multidisciplinary facial pain clinics.
Head teachers’ change facilitation styles and teachers’ concerns about ICT integration
Authors: Jogezai Nazir Ahmed , Ismail Shaik Abdul Malik Mohamed , Baloch Fozia Ahmed
Published: June 2020

The study aimed to identify the influence of head teachers’ change facilitator styles (CFS) on teachers’ concerns about ICT integration. The three CFS (responder, manager and initiator) were studied in relation to its influence on teachers’ seven stages of concern (unconcerned, informational, personal, management, consequence, collaboration and refocusing) about ICT integration. Both styles and concerns are embodied in the concerns-based adoption model, which guided the theoretical framework of the study. This quantitative study used CFS and stages of concerns questionnaire to collect data from 276 secondary school teachers. Initially, teachers’ concerns were explored, followed by head teachers’ CFS and their influence on teachers’ concerns about ICT integration. The results showed that secondary school teachers’ concerns, regarding ICT integration, were at the initial stages as reflected by their high mean scores on personal and informational stages. Findings inform about the responder as a dominant CFS used by secondary school head teachers. The data suggest differences in terms of the influence of head teachers’ three CFS on teachers’ concerns about ICT integration.
The National Health Service’s ‘special measures’: Cambridge – A case study
Authors: Purohit Katie
Published: June 2020

The United Kingdom’s (UK) National Health Service (NHS) has a procedure, ‘special measures’, which is used to implement changes to a Trust when there are concerns about the quality of care being delivered. This case study uses the London Protocol to analyse how a plethora of factors contributed to an ‘inadequate’ rating and the subsequent initiation of the special measures procedure at Cambridge University Hospitals (CUH) in September 2015. External factors such as legal and political reform have a strong influence on healthcare as well as the substantial internal forces within the state-led NHS including finance, culture and management. Factors specific to CUH also had a significant role to play: the early adoption of a complete digital record system, costing over £200 m, adversely affected CUH Trust at this time and was implicated as a major factor in its inadequate performance. In addition, the Care Quality Commission (CQC) identified many other important shortcomings at CUH. The London Protocol is used to bring clarity and structure to the complexities of the Health Services Industry, both within and surrounding CUH during this period.
Effect of joint stiffness and size on stability of three-way single-layer cylindrical reticular shell
Authors: Li Hui-jun , Taniguchi Yoshiya
Published: June 2020

The main aim of the present article is to study the effect of joint stiffness and joint size on load-carrying capacity of single-layer cylindrical reticular shell. One normalized joint bending stiffness index κb and three proposed normalized indexes, that is, normalized joint axial stiffness κa, normalized joint shear stiffness κs, and normalized joint torsional stiffness κt, are used to evaluate the stiffness of joint. Through a large number of numerical computations, the main conclusions are summarized as follows: κb has a significant effect on limit load of reticular shell, and this effect has a close relationship to rise-to-span ratio of reticular shell. If κb is larger than 30, the joint can be treated as rigid joint. The relationship between the logarithm of κb and limit load of reticular shell can be expressed by the logistic formulation. Overall rigidity and load-carrying capacity of reticular shell are greatly influenced by joint axial stiffness. If κa is larger than 30, the effect of joint axial stiffness on load-carrying capacity of reticular shell is no longer obvious. Otherwise, the load-carrying capacity will be markedly reduced. The relation between the logarithm of κa and limit load of reticular shell can be fitted by the Dose–response formulation. The load-carrying capacity of reticular shell is also influenced by joint torsional stiffness and joint shear stiffness to some extent. The relation between the logarithm of κs and limit load can be fitted by the Asymptotic formulation. The effect of joint size on overall rigidity and limit load of reticular shell is evident and cannot be neglected. The limit load gradually decreases with the decrease in joint size, and there is an approximate linear relationship between limit load and joint size.
Past and future sky-island dynamics of tropical mountains: A model for two Geotrupes (Coleoptera: Geotrupidae) species in Oaxaca, Mexico
Authors: Arriaga-Jiménez Alfonsina , Kohlmann Bert , Vázquez-Selem Lorenzo , Umaña Yhenner , Rös Matthias
Published: June 2020

Recent collecting and taxonomic studies of dung beetles of the genus Geotrupes Latreille (Coleoptera: Geotrupidae) in the mountains of Oaxaca have evidenced the existence of a vicariant speciation pattern, where one species occupies the northern mountain system and the other one the southern mountain range. A study of this possible vicariant speciation mechanism is presented using a paleobiogeographic mapping analysis of both Geotrupes species distribution during Late Quaternary glaciation events. Based on these paleomaps a possible speciation mechanism (vicariant speciation) is suggested, in which one common ancestor (mother species) lived at the bottom of the Valle de Oaxaca (Oaxaca Valley) during the last local glacial maximum (LLGM, 21-17.5 kyr) and whose possible continuous distribution was broken into two (or more) separated areas on mountaintops as the climate became warmer toward the present. We propose that the fragmentation and isolation of habitats may have promoted genetic differentiation of populations resulting in vicariant speciation, as suggested by a sky-island dynamic process. The example of a possible effect of the Little Ice Age in the mountains of Oaxaca is also discussed. Finally, a projection is made into the XXII century, based on climatic modeling predictions. These last results suggest the possible disappearance of the sky-island dynamic process through the accelerated speed of climatic change.
What science means to me: Understanding personal identification with (evolutionary) science using the sociology of (non)religion
Authors: Jones Stephen H. , Elsdon-Baker Fern , Catto Rebecca , Kaden Tom
Published: June 2020

Within science and technology studies, there is an established tradition of examining publics’ knowledge of, trust in, access to and engagement with science, but less attention has been paid to whether and why publics identify with science. While this is understandable given the field’s interest in bridging gaps between publics and producers of scientific knowledge, it leaves unanswered questions about how science forms part of people’s worldviews and fits into cultural politics and conflict. Based on 123 interviews and 16 focus groups with mixed religious and nonreligious publics and scientists in the United Kingdom and Canada, this article utilises approaches from the sociology of (non)religion to delineate varieties of science identification. It maps out ‘practical’, ‘norm-based’, ‘civilisational’ and ‘existential’ identifications and explores how these interrelate with people’s social characteristics. The article illustrates how science identification is typically dependent on a constellation of cultural/political influences rather than just emerging out of interest in science.
Factors associated with attendance and attendance patterns in a population-based mammographic screening program
Authors: Larsen Marthe , Moshina Nataliia , Sagstad Silje , Hofvind Solveig
Published: June 2020

Objective

To explore the factors associated with attendance and attendance pattern in BreastScreen Norway.

Methods

We evaluated the number of invitations (n = 1,253,995) and attendances, 2015–2019, stratified by age, invitation method, screening unit and time of appointment. Attendance pattern was analysed for women invited 10 times (n = 47,979), 1996–2019. The association of education level, body mass index, physical activity and smoking status with attendance was analysed for a sub-sample of women (n = 37,930). Descriptive statistics were used to analyse attendance, and negative binomial regression was used to analyse the association between the total number of attendances and education level and lifestyle factors.

Results

The attendance rate was 76.0%, 2015–2019. The rate was 78.0% for women aged >64 and 73.9% for those <55 . We found a rate of 82.0% for women who received a digital invitation, while it was 73.7% for those invited by post. The rate was 78.1% for invitations in the late afternoon, 3–6 p.m., while later appointments reached a rate of 73.7%. Half of the women invited 10 times attended all times. The predicted total number of attendances was 9 out of 10 for the factors investigated.

Conclusion

The highest attendance rates were shown for women aged >64, those who received digital invitations and those having appointments in late afternoon. The differences in predicted number of attendances between the investigated factors were minor. Overall, BreastScreen Norway has a high attendance rate. However, efforts aimed at increasing the attendance in specific groups should be considered.
Are Time Management and Cyberloafing Related? Investigating Employees’ Attitudes
Authors: Ötken A. Begüm , Bayram Ayhan , Beşer Senem Göl , Kaya Çiğdem
Published: June 2020

Time is a critical commodity both for individuals and companies because it is not possible to substitute or purchase it. The concept of time management, therefore, attracted the attention of both academicians and practitioners. Companies started to question behaviour of employees using their companies’ Internet access for non-work-related purposes during work hours. These activities constitute an unproductive use of time and detract employees from completing their work demands. In this framework, the purpose of this study is to understand whether time management and cyberloafing are related. Data were collected from 300 employees working in Istanbul, Turkey. Results show that the time wasters dimension negatively explained the variance in serious cyberloafing. Results also show that time planning and time attitude dimensions positively explained the variance in minor cyberloafing. Understanding the relationship between time management and cyberloafing provides fruitful results for companies and individuals in terms of productivity and achieving goals at work.
Fish Cells, a new zero Poisson’s ratio metamaterial—Part I: Design and experiment
Authors: Naghavi Zadeh Mohammad , Dayyani Iman , Yasaee Mehdi
Published: June 2020

A novel cellular mechanical metamaterial called Fish Cells that exhibits zero Poisson’s ratio in both orthogonal in-plane directions is proposed. Homogenization study on the Fish Cells tessellation is conducted and substantially zero Poisson’s ratio behavior in a homogenized tessellation is shown by numerical analysis. Experimental investigations are performed to validate the zero Poisson’s ratio feature of the metamaterial and obtain force–displacement response of the metamaterial in elastic and plastic zone. A detailed discussion about the effect of the numerical model approach and joints on the structural response of the metamaterial is presented. Morphing skin is a potential application for Fish Cells metamaterial because of the integration benefits of zero Poisson’s ratio design. The structural integrity of the Fish Cells is investigated by studying the stiffness augmentation under tension and in presence of constraints on transverse edges. Finally, geometrical enhancements for improved integrity of the Fish Cells are presented that result in substantially zero stiffness augmentation required for morphing skins.
Riemannian and Euclidean material structures in anelasticity
Authors: Sozio Fabio , Yavari Arash
Published: June 2020

In this paper, we discuss the mechanics of anelastic bodies with respect to a Riemannian and a Euclidean geometric structure on the material manifold. These two structures provide two equivalent sets of governing equations that correspond to the geometrical and classical approaches to non-linear anelasticity. This paper provides a parallelism between the two approaches and explains how to go from one to the other. We work in the setting of the multiplicative decomposition of deformation gradient seen as a non-holonomic change of frame in the material manifold. This allows one to define, in addition to the two geometric structures, a Weitzenböck connection on the material manifold. We use this connection to express natural uniformity in a geometrically meaningful way. The concept of uniformity is then extended to the Riemannian and Euclidean structures. Finally, we discuss the role of non-uniformity in the form of material forces that appear in the configurational form of the balance of linear momentum with respect to the two structures.

Political parties and citizens’ well-being among non-democratic developing countries
Authors: Bellinger Nisha
Published: June 2020

This article explains variations in citizens’ well-being among non-democratic developing countries by disaggregating non-democracies and focusing on the role of party strength. The effect of party strength is analyzed through the prisms of information and capacity. I argue that stronger parties facilitate a two-way flow of information between citizens and political leaders about societal needs. Additionally, stronger parties have the capacity to aggregate information and formulate policies that meet the needs of the citizenry. The theory is tested through a time-series-cross-sectional analysis of developing non-democracies and is supplemented with a case narrative on Rwanda. The findings demonstrate the significance of disaggregating non-democratic regimes to better understand the political dynamics of citizens’ well-being.
Women’s perceived contributions to diversity: The impact of target race and contextual gender salience
Authors: Geerling Danielle M. , Chen Jacqueline M.
Published: June 2020

Diversity is a desired attribute for many organizations. Yet, there is limited scientific understanding of what leads people to perceive diversity, and past studies focus on racial diversity to the exclusion of other social identities. We investigated how an individual’s race and gender conjointly impact their perceived contributions to organizational diversity and whether context-driven gender salience affects these judgments. Study 1 established that, in the absence of an organizational context, women of color are considered to contribute more to diversity than men of color, White women, and White men. In Studies 2A–2C, we manipulated an organization’s demographic composition and found that female representation affected White women’s perceived contributions to diversity more than Black women’s perceived contributions to diversity. Similarly, in Study 3, we found that an organization’s history of gender discrimination increased White women’s, but not Black women’s, perceived contributions to diversity. This research has implications for diversity-related hiring decisions.
Informed consent for paradata use in web surveys

Published: June 2020

Paradata are a valuable source of information to better understand the response process and to determine how the data collection processes can be improved. Currently, a debate is ongoing in academia and in the professional associations of market, opinion, and social research concerning the need to inform respondents about the collection and use of their web paradata. Unfortunately, research is lacking on the design of informed consent for web paradata use and its possible consequences for respondents’ willingness to share their paradata, completion of a survey, and response behavior. The aim of this study is to provide guidance to the survey practitioner on the optimal design of informed consent for web paradata use based on experimental evidence.
Is freedom as non-domination a right-wing idea?
Authors: Richard Stanislas Victor
Published: June 2020

Sean Irving’s book Hayek’s Market Republicanism: The Limits of Liberty shows that the commonly accepted reading of Hayek as a liberal thinker is mistaken, and that his political writings are best understood as belonging to the broader tradition of republicanism. The distinction is important for understanding many aspects of Hayek’s thought, and especially his rejection of social justice and majoritarian democracy. In that sense, one of the book’s more general merits is its implicit contribution to ongoing debates between republican ‘freedom as non-domination’ and liberal ‘freedom as non-interference’. Irving focuses on what he sees as a contradiction between Hayek’s chief concerns about the state as the main source of domination and his disregard for private forms of power, and especially within the capitalist firm. I argue, however, that the example of Hayek should lead us to consider a more prosaic conclusion: freedom as non-domination is a concept less useful for criticising the free market than Irving and left-leaning Republicans seem to assume.
Readiness for Tobacco-Free Policy in a Statewide University System

Published: June 2020

Background. Almost 2,000 campuses have adopted tobacco-free (TF) policies across the United States. However, there is not a systematic process to help campuses implement successful policies. Readiness assessments can help provide assistance as campuses work to implement successful policies. Purpose. We assessed readiness for TF policies among campuses of a statewide university system and determined factors associated with readiness. Participants. Stakeholders from 23 campuses without 100% TF policies were invited to participate in an online survey. Method. System administrators provided contacts for five to eight stakeholders per campus. Included in the analysis were 10 of 23 campuses (43.5%) with at least three stakeholders completing the survey. Results. Of the 10 campuses, one was in Preplanning, five were in Preparation, and four were in the Initiation stage of readiness. Political Climate was the highest scored dimension on seven campuses (0.74–1.0); Resources was the lowest on eight campuses (0.0–0.67). Campus size and county rurality were each associated with one dimension score. Conclusions. Despite being part of a statewide university system, campuses are in varying stages of readiness for TF policies. Stage-based strategies to advance TF campus policies must be implemented to set campuses up for successful policies.

The remarkable resurgence of fiber metal laminates (FMLs) is certainly attributed to the hybrid properties inherent to light metals and fibers reinforced polymer (FRP). There are few reports on the role of nano-size reinforcements in these composites. In this study, the effect of graphene nanoplatelets (GNPs) on the flexural and Charpy impact properties of FMLs of aluminum (Al) 2024 reinforced with hybrid glass/Kevlar fibers-epoxy was investigated. Different wt.% of GNPs (0.0, 0.1, 0.25 and 0.5) and hand lay-up method were used to fabricate nano-FMLs followed by evaluating them in three-point bend and Charpy impact tests. Before making the FMLs, the surfaces of Al sheets were modified to generate surface pores/nano-pores in order to improve the interfacial bonding within the FMLs layers. The FMLs containing 0.1 wt.% GNPs exhibited 10%, 9% and 11% improvement in flexural strength and modulus and impact strength, respectively, compared to the FMLs containing 0.0 wt.% GNPs. Increase of the GNPs to 0.25 wt.% caused a reduction of the flexural strength and modulus and impact strength values; 13.7%, 3% and 25.5% compared to the samples without GNPs. Also increase of the GNPs to 0.5 wt.% decreased these properties to 31.3%, 8.8% and 29.5%. Scanning electron microscopy (SEM) observations of their fracture surfaces showed better adhesion at both polymer/fibers (within the FRP) and Al/FRP interfaces. However, at higher wt.% of GNPs, the FMLs became weaker and more brittle. Agglomerated GNPs at the Al/FRP interface penetrated/filled the surface pores/nano-pores on the Al surfaces. Therefore prevent the polymer penetration in pores, resulting in weak interfacial bond and thus overall weaker and less ductile FMLs. As a result, the Charpy impact values for the 0.25 and 0.5 wt.% GNPs samples were respectively 33 and 37 percent smaller than that for the 0.1 wt.% GNPs sample.
Atherectomy with balloon angioplasty compared to balloon angioplasty alone for the treatment of chronic limb threatening ischemia: A national surgical quality improvement program database analysis

Published: June 2020

Objectives

To compare perioperative outcomes related to atherectomy with percutaneous transluminal angioplasty versus percutaneous transluminal angioplasty alone for the treatment of lower extremity chronic limb threatening ischemia using a national patient database.

Methods

Patients with chronic limb threatening ischemia treated with atherectomy and percutaneous transluminal angioplasty or percutaneous transluminal angioplasty alone from 2011 to 2016 in the National Surgical Quality Improvement Program database were identified. Primary outcomes were major adverse limb events (30-day untreated loss of patency, major reintervention, major amputation) and major adverse cardiac events (cardiac arrest, composite outcome of myocardial infarction or stroke). Secondary outcomes included 30-day mortality, length of stay, and any unplanned readmission within 30 days. Multivariate regression analyses were performed to determine independent predictors of outcome. Propensity score matched cohort analysis was performed. A p-value <0.05 was considered statistically significant. Subgroup analyses of femoropopliteal and infrapopliteal interventions were performed.

Results

In total, 2636 (77.2%) patients were treated with percutaneous transluminal angioplasty and 778 (22.8%) were treated with atherectomy and percutaneous transluminal angioplasty. Multivariate analyses of the unadjusted cohort revealed no significant differences in major adverse cardiac events or major adverse limb events between the two groups ( p-value >0.05). Subgroup analysis of femoropopliteal interventions demonstrated a significantly decreased likelihood of untreated loss of patency in 30 days in the atherectomy group compared to the percutaneous transluminal angioplasty group (1.1% vs. 2.7%, respectively; p-value = 0.034), which persisted on propensity score matched analysis (1.1% vs. 3.1%, respectively; p-value = 0.026).

Conclusion

Atherectomy with balloon angioplasty of femoropopliteal disease provides a significant decrease in untreated loss of patency compared to balloon angioplasty alone.
Thoracic endovascular repair for disseminated intravascular coagulation associated with chronic type B aortic dissection
Authors: Yamamoto Jumpei , Hiraoka Arudo , Yoshitaka Hidenori
Published: June 2020

Objectives

Chronic disseminated intravascular coagulation is a rare complication of aortic dissection, and its optimal treatment remains controversial.

Methods

We present a 78-year-old man with repeated hemorrhagic events by disseminated intravascular coagulation due to chronic aortic dissection treated by thoracic endovascular aortic repair.

Results

Computed tomography angiography at three months revealed a completely thrombosed false lumen from the distal aortic arch to the descending aorta at the celiac artery level. Platelets and D-dimer levels remained stable, and the patient was doing well without hemorrhagic complications.

Conclusions

Endovascular repair was effective for disseminated intravascular coagulation due to chronic type B aortic dissection.
