Observations of Extreme Short-Term Precipitation Associated with Supercells and Mesovortices
Authors: Nielsen Erik R. , Schumacher Russ S.
Published: October 2019

Extreme hourly rainfall accumulations (e.g., exceeding 75 mm h−1) in several noteworthy flash flood events have suggested that the most intense accumulations were attendant with discrete mesoscale rotation or rotation embedded within larger organized systems. This research aims to explore how often extreme short-term rain rates in the United States are associated with storm-scale or mesoscale vortices. Five years of METAR observations and three years of Stage-IV analyses were obtained and filtered for hourly accumulations over 75 and 100 mm, respectively, clustered into events, and subjectively identified for rotation. The distribution of the short-term, locally extreme events shows the majority of the events were located along the Atlantic and Gulf of Mexico coastlines with additional events occurring in the central plains and into the Midwest. Nearly 50% of the cases were associated with low-level rotation in high-precipitation supercells or mesoscale vortices embedded in organized storm modes. Rotation events occurred more clearly in the warm sector, while nonrotation events tended to occur along a surface boundary. The rotation events tended to produce higher hourly accumulations over a larger region, but were associated with somewhat stronger synoptic-to-mesoscale forcing for ascent and more total column moisture. These results support recent modeling results suggesting that rotationally induced dynamic vertical pressure perturbations should not be ignored when it comes to extreme precipitation and can potentially enhance the short-term rain rates.
Moral Authenticity in a Turbulent Age: Charles Taylor and the Diary of Etty Hillesum
Authors: Lalonde Marc P.
Published: October 2019

This paper explores the relation between the moral philosophy of Charles Taylor and the wartime diary of Etty Hillesum. Written in Amsterdam between 1941 and 1942, Hillesum’s diary records her effort to construct a meaningful identity in relation to the Nazi occupation of the Netherlands. That effort, I want to claim, is clarified via an interface with Taylor’s notion of “authenticity.” Taylor argues that authenticity constitutes a moral ideal that serves to measure the worth and value of the lived life. Such is the fundamental mission of Hillesum. In the final analysis I argue that Taylor’s moral philosophy lends structure, form and substance to Hillesum’s thought, while Hillesum’s journey vivifies the veracity of Taylor’s project. Her life situation both embodies and expresses the contemporaneity of Taylor’s work and illuminates its existential significance. Thus the importance of authenticity is not just a philosophical hypothesis but an issue with historical flesh and bone. Or so suggests Hillesum’s search for authenticity in a turbulent age.
Do Prison Administrative and Survey Data Sources Tell the Same Story? A Multitrait, Multimethod Examination With Application to Gangs
Authors: Pyrooz David C. , Decker Scott H. , Owens Emily
Published: October 2019

Measurement is critical to advancing theory and research in criminology. Yet, criminologists are often forced to rely on data sources that are not intended to be used for research or collected in contexts where subjects may have incentives to misreport. This is particularly true of data in institutional corrections research. This study leveraged novel data to examine correspondence in key measures found in prison administrative and survey data on 802 prisoners in Texas, focusing on the measurement properties of an important group rarely studied in prison: gang members. We observed high rates of correspondence between data sources for gang membership (82%) and the gang with which they were affiliated (86%). A multilevel test of item correspondence demonstrated that the measures of gang membership performed as well or better than more episodic measures and worse than more durable measures common in corrections research. A multitrait, multimethod matrix revealed that gang membership, and nearly all other measures, satisfied the principles of validity. Finally, there were no differences in correspondence rates between gang and nongang members for nearly every measure, regardless of the method to measure gang membership. Prison administrative and survey data generally tell the same story, which is promising for institutional corrections research, particularly research focused on gangs.
The social innovation–(re)politicisation nexus: Unlocking the political in actually existing smart city campaigns? The case of SmartCity Cologne, Germany
Authors: Leitheiser Stephen , Follmann Alexander
Published: October 2019

As a prominent and performative discourse, The Smart City has the potential to shape urban futures. Yet, its mostly top-down implementation and dominantly technocratic definition of problems raises critiques of The Smart City as the latest version of a series of post-political and neoliberal visions of urban governance. However, as smart cities are implemented into ‘actually existing’ strategies locally, they are always negotiated and translated into place-specific contexts. Beyond critiquing the powerful discourse of The Smart City, the social innovation–(re)politicisation nexus (SIRN) spells out a framework for contesting and co-producing radically transformative smart city visions and politics as they take shape on the ground. Linking the empirical case study of the ‘top-down’ implementation of SmartCity Cologne, Germany, to current ‘bottom-up’ discourses on reclaiming the urban commons, we show how ‘true’ and ‘real’ social innovation must go hand-in-hand with a re-politicisation of hegemonic logics and discursive framings. In doing so, this paper makes theoretical and empirical contributions to public and academic discourse on which governance practices, methods and policies could contribute to radical transformations towards a ‘truly’ smart and sustainable urban future.
Leave the Dead Some Room to Dance: Postcolonial Founding and the Problem of Inheritance in Wole Soyinka’s A Dance of the Forests
Authors: Suell David Thomas
Published: October 2019

In this essay, I examine Nigerian playwright Wole Soyinka’s A Dance of the Forests in order to think through political founding. Viewing founding from the postcolonial context, I explore how members of a political community negotiate among the multiple pasts that continue to affect them, and what kind of institutions and actors are best equipped to pursue this critical part of the founding project. Situating Soyinka’s account against competing narratives of the postcolonial condition, I demonstrate how he uses Yoruba philosophy and cosmology to reframe the challenges and potentials of founding, and I illustrate how political actors should respond to these by adopting the role of “citizen-artists” who can learn from past struggles and overcome their overwhelming legacies. Read as a dramatic intervention into Nigerian democratic politics and as a work of political theory, A Dance offers a lens through which to interrogate founding within and beyond the postcolony.
Desegregation of City Parks and the Civil Rights Movement: The Case of Oak Park in Montgomery, Alabama
Authors: Retzlaff Rebecca
Published: October 2019

This article analyzes the history of desegregation of city parks in Montgomery, Alabama. The article chronicles the sixteen-year legal battle to desegregate parks in Montgomery and the efforts of city officials to keep parks segregated, including closing all of the parks for seven years, contracting with the Montgomery YMCA to operate segregated private recreation facilities, and allowing only segregated schools to use the parks. The article explores the connection between park segregation and the Montgomery Bus Boycott and school segregation, and questions why public officials fought to keep parks segregated after other public facilities began court-ordered desegregation, and why the story of park desegregation in Montgomery is largely unknown. The article concludes with a call to confront the history of park segregation in Montgomery.
A Meta-Analytic Review of Randomized Controlled Trials of the Good Behavior Game
Authors: Smith Stephanie , Barajas Kimberly , Ellis Brandi , Moore Christina , McCauley Spencer , Reichow Brian
Published: October 2019

The Good Behavior Game (GBG) is widely recognized as an evidence-based intervention that reinforces prosocial behaviors and discourages disruptive behaviors among students in the classroom setting. The current meta-analysis synthesized randomized controlled trials of the GBG to examine its impact on proximal student outcomes across seven studies representing 4,700 children. Although recent reviews focusing on single-case studies of the GBG have reported moderate to large treatment effects, our results were quite modest in comparison (hedges’ g = 0.09-0.32). Treatment effect sizes also varied according to outcome and sex. The GBG significantly outperformed the comparison conditions for peer-rated conduct problems and shy/withdrawn behavior as well as teacher-rated conduct problems for which a greater effect was found for girls relative to boys. Moreover, the treatment effect in favor of the GBG for reading comprehension was specific to boys and not girls. No significant differences were found between the GBG and comparison conditions for inattention and teacher-rated shy/withdrawn behavior. These results suggest that the GBG may not be as impactful as originally reported and the intended population and treatment targets should be considered before its implementation in the classroom.
Recognising the caring capabilities of birth families of removed children: Towards a critical policy agenda
Authors: Healy Karen
Published: October 2019

Vulnerable families are subject to a myriad of State interventions. In this article, we analyse how interventions of the neo-liberal State may undermine, rather than activate, the caring capabilities of vulnerable families across the life course. We define ‘vulnerable families’ as financially disadvantaged families with complex and enduring needs. Drawing on examples from Australia, England and the USA, we consider how neo-liberal policy reforms may weaken the caring capabilities of these families. We focus our analysis on vulnerable families who have been subject to one of the most intrusive forms of state intervention: the removal of a child. We explain Bourdieu’s concept of ‘misrecognition’ and outline its utility for analysing the neo-liberal state’s failure to recognise and develop the caring function of birth families. We consider the implications of this analysis for the development of a critical research and policy agenda with vulnerable families.
Estimating Long-Term Drinking Patterns for People with Lifetime Alcohol Use Disorder
Authors: Barbosa Carolina , Dowd William N. , Aldridge Arnie P. , Timko Christine , Zarkin Gary A.
Published: October 2019

Background. There is a lack of data on alcohol consumption over time. This study characterizes the long-term drinking patterns of people with lifetime alcohol use disorders who have engaged in treatment or informal care. Methods. We developed multinomial logit models using the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) to estimate short-term transition probabilities (TPs) among the 4 World Health Organization drinking risk levels (low, medium, high, and very high risk) and abstinence by age, sex, and race/ethnicity. We applied an optimization algorithm to convert 3-year TPs from NESARC to 1-year TPs, then used simulated annealing to calibrate TPs to a propensity-scored matched set of participants derived from a separate 16-year study of alcohol consumption. We validated the resulting long-term TPs using NESARC-III, a cross-sectional study conducted on a different cohort. Results. Across 24 demographic groups, the 1-year probability of remaining in the same state averaged 0.93, 0.81, 0.49, 0.51, and 0.63 for abstinent, low, medium, high, and very high-risk states, respectively. After calibration to the 16-year study data ( N = 420), resulting TPs produced state distributions that hit the calibration target. We find that the abstinent or low-risk states are very stable, and the annual probability of leaving the very high-risk state increases by about 20 percentage points beyond 8 years. Limitations. TPs for some demographic groups had small cell sizes. The data used to calibrate long-term TPs are based on a geographically narrow study. Conclusions. This study is the first to characterize long-term drinking patterns by combining short-term representative data with long-term data on drinking behaviors. Current research is using these patterns to estimate the long-term cost effectiveness of alcohol treatment.
Effects of dasatinib on CD8+T, Th1, and Treg cells in patients with chronic myeloid leukemia
Authors: Wei Xiaoqing , He Lin , Wang Xiaodong , Lin Min , Dai Jingying
Published: October 2019

Objective

To investigate the immunomodulatory effects of the tyrosine kinase inhibitor (TKI) dasatinib on T-cell subtypes in patients with chronic myeloid leukemia (CML).

Methods

T helper (Th) 1, Th2, regulatory T (Treg), and CD8+T cell levels were detected in patients with CML (n = 9) before and after dasatinib treatment. The corresponding response level at the time of a blood test was evaluated.

Results

After dasatinib treatment, six patients achieved a better response level, while three did not show improved response levels. Among the total nine patients, there were no significant differences in Th1, Th2, and Treg cell levels, whereas CD8+T cell levels were significantly increased after dasatinib treatment compared with before treatment. When we analyzed the six patients who obtained a better response level, Th1 and CD8+T cell levels were significantly increased after dasatinib treatment, but Th2 and Treg cell levels did not change. The other three patients who did not have improved response levels showed decreased Th1 cell levels and increased Treg cell levels after treatment.

Conclusions

Dasatinib may increase Th1 and CD8+T cell levels, and decrease Treg cell levels in patients with CML. This finding might be associated with a good therapeutic response to this drug.
Incarcerated recurrent inguinal hernia as a cause of secondary torsion of the greater omentum: a rare case report and literature review
Authors: Yang Qian , Gao Yunhan
Published: October 2019

Torsion of the greater omentum is a rare condition with a low incidence. However, secondary torsion of the greater omentum caused by an incarcerated recurrent inguinal hernia is extremely rare. Such torsion is fairly difficult to diagnose preoperatively because the symptoms are not typical and can mimic those of other causes of acute abdominal disease. If only the incarcerated inguinal hernia is treated, associated torsion of the greater omentum may be missed. We herein report a case of secondary torsion of the greater omentum caused by an incarcerated recurrent inguinal hernia. Exploratory laparotomy was performed because the preoperative computed tomography findings suggested torsion of the greater omentum. The diagnosis of torsion of the greater omentum was confirmed intraoperatively. The patient developed no recurrence throughout the 5-year follow-up.
Conducting systematic literature reviews and bibliometric analyses
Authors: Linnenluecke Martina K , Marrone Mauricio , Singh Abhay K
Published: October 2019

Literature reviews play an essential role in academic research to gather existing knowledge and to examine the state of a field. However, researchers in business, management and related disciplines continue to rely on cursory and narrative reviews that lack a systematic investigation of the literature. This article details methodological steps for conducting literature reviews in a replicable and scientific fashion. This article also discusses bibliographic mapping approaches to visualise bibliometric information and findings from a systematic literature review. We hope that the insights provided in this article are useful for researchers at different stages of their careers – ranging from doctoral students who wish to assemble a broad overview of their field of interest to guide their work, to senior researchers who wish to publish authoritative literature reviews.

City Branding and the Link to Urban Planning: Theories, Practices, and Challenges
Authors: Bonakdar Ahmad , Audirac Ivonne
Published: October 2019

Through a critical reading of city branding theories and practices, this article identifies a nexus between city branding and urban planning related to master planning and placemaking. It brings attention to the challenges facing city branding including asymmetrical political processes, social inequity, tokenism, and gentrification. While city branding’s recent turn to participatory approaches unveils a rampant adoption of planning processes repackaged as master planning the place brand strategy, this stream of research and practice remains isolated and disconnected from urban planning theory and ethics. Recognizing this link, the article suggests, could help city branding address its challenges and develop its theoretical basis with more socially responsible and normative underpinnings.
Qualitative phenomenological investigation of the transient temperature gradient during gas turbine's hot section component cooling
Authors: Tahsini AM
Published: October 2019

In this study, the temporal variation of temperature gradient in the gas turbine hot section components in the transient process is raised, and according to its impact on life expectancy computations, the accuracy of the usual methods is investigated qualitatively. It is worth noting that in such two-phase problems, existing different time-scales prevent some common simplifications that are usually used for unsteady investigations like a quasi-steady assumption, and so there is no choice but to conduct coupled transient studies despite their high time-consuming manner. Hence, the phenomenological and qualitative model is introduced to analyze the cooling problem and show the transient behavior. The results show that during unsteady operations, if the time rate of changes is high, some considerable overshoots (more than 30%) of temperature gradients in hot sections may be ignored in common quasi-steady predictions, which must be predicted only by using the unsteady and coupled simulations.
Salt template zirconia reinforcing particles as possible reinforcement for PMMA matrix composite

Published: October 2019

To obtain flakes like zirconia particles at relatively low temperature, the synthesis method for producing zirconia particles on the surface of salt particles that serve as a template is examined. The produced particles are incorporated as reinforcement in the poly(methyl methacrylate) matrix to obtain a composite material. The particles were characterized by the X-ray diffraction, Fourier-transform infrared spectroscopy, and image analysis. The morphology of the particles and composites was examined using a field emission scanning electron microscope. Composites prepared with synthesized particles were compared to those containing commercial zirconia particles to estimate the possibility of use of synthesized particles as reinforcement. The influence of the 1 wt% of zirconia particles in composite material on the mechanical properties was studied using microhardness measurements and dynamic mechanical analysis. The results obtained show that the addition of 1 wt% of zirconia particles increases the mechanical properties of the composite relative to the pure polymer matrix.
A Study on the Two-way Causal Relationship Between Industrial Structure Evolution and Economic Growth: Empirical Test Based on 40 Years of Reform and Opening-up in China
Authors: Liu Qingjie , Hu Biliang
Published: October 2019

The adjustment of industrial structure is an important engine driving the economic growth. The relationship between industrial structure evolution and economic growth is characterized by various stages. The article uses the data of 31 provincial units in China from 1978 to 2016 as a sample, divided into five stages with time as nodes, and takes the rationalization and optimization of industrial structure (OIS) as indicators to measure the adjustment of industrial structure. The main research conclusions are obtained through cointegration test, Granger test and simultaneous equation model. Results indicate that the relationship between OIS and economic growth shows the characteristics of mutual influence, while the rationalization of industrial structure unilaterally affects economic growth. Rationalization of industrial structure has significantly stimulated economic growth, especially in the past 10 years after China’s accession to the World Trade Organization (WTO). The stimulating effect of OIS on China’s economic growth has not yet been fully demonstrated. This indicates that the OIS, as a new momentum of economic growth, has not yet been brought into presently in China. Economic growth has a driving effect on the OIS. However, it is only when the economic development enters a relatively mature stage can this driving effect be gradually brought into play.
Talking about the ‘rotten fruits’ of Rio 2016: Framing mega-event legacies
Authors: Talbot Adam
Published: October 2019

Legacy has become a watchword of hosting mega-events in recent years, used to justify massive spending and far-reaching urban transformations. However, academic studies of legacy outcomes suggest there is only limited evidence for the efficacy of using mega-events to deliver broader policy goals. The discourse of legacy promulgated by the International Olympic Committee promotes a fantastical vision of the possibilities created by mega-events while obfuscating critical analyses of legacy. This paper explores legacy talk among a wholly different group – activists who have protested against the Olympic Games, specifically in Rio de Janeiro – based on interviews conducted two years after the Games as part of a broader ethnographic study. The positive connotations of legacy, even among these Olympic critics, places a straitjacket on conversation, leading activists to discuss specific legacy projects, at the expense of highlighting the very real harms of mega-event development, such as evictions, gentrification and militarization. As such, there is a need to deepen understanding that legacy encompasses all that is left behind after mega-events, not only the positive impacts.
Evolutionary active vision system: from 2D to 3D
Authors: Lanihun Olalekan , Tiddeman Bernie , Shaw Patricia , Tuci Elio
Published: October 2019

Biological vision incorporates intelligent cooperation between the sensory and the motor systems, which is facilitated by the development of motor skills that help to shape visual information that is relevant to a specific vision task. In this article, we seek to explore an approach to active vision inspired by biological systems, which uses limited constraints for motor strategies through progressive adaptation via an evolutionary method. This type of approach gives freedom to artificial systems in the discovery of eye-movement strategies that may be useful to solve a given vision task but are not known to us. In the experiment sections of this article, we use this type of evolutionary active vision system for more complex natural images in both two-dimensional (2D) and three-dimensional (3D) environments. To further improve the results, we experiment with the use of pre-processing the visual input with both the uniform local binary patterns (ULBP) and the histogram of oriented gradients (HOG) for classification tasks in the 2D and 3D environments. The 3D experiments include application of the active vision system to object categorisation and indoor versus outdoor environment classification. Our experiments are conducted on the iCub humanoid robot simulator platform.

Published: October 2019

Background:

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Thus, the aim of our study was to evaluate the smartphone-based electrocardiogram (ECG) recordings aimed at AF screening at Polish pharmacies.

Methods:

Prospective AF screening among patients aged ≥65 years was conducted at 10 pharmacies using Kardia Mobile with a dedicated application (Kardia app). Prior AF was a study exclusion criterion. CHA2DS2-VASc score (congestive heart failure, hypertension, age, diabetes mellitus, previous stroke/transient ischemic attack, female sex, and vascular disease) has been collected from every patient. A single-lead ECG has been acquired by the placement of fingers from each hand on the pads. Kardia app diagnosis has been evaluated by the cardiologist.

Results:

A total of 525 ECGs were performed. Kardia app diagnosis was provided in 490 cases. In 437 (89.18%) cases, it was “normal” rhythm, in 17 (3.47%) recordings “possible AF,” in 23 (4.69%) ECGs “unreadable,” and in 13 (2.65%) “unclassified”. After the cardiologist reevaluation, the new AF was identified in 7 (1.33%) patients. Sensitivity and specificity of Kardia app in detecting AF was 100% (95% confidence interval [CI]: 71.5%-100%) and 98.7% (95% CI: 97.3%-99.5%), respectively. The positive predictive value was 64.7% (95% CI: 38.3%-85.7%) and the negative predictive value was 100% (95% CI: 99.2%-100%). CHA2DS2-VASc score was 2.14 ± 0.69 for those with new AF and 3.33 ± 1.26 in the non-AF group.

Conclusion:

Kardia app is capable of fast screening and detecting AF with high sensitivity and specificity. The possible diagnosis of AF deserves additional cardiological evaluation. The results obtained in patients with low CHA2DS2-VASc score and “silent” AF confirm the importance of routine AF screening. Cardiovascular screening with the use of mobile health technology is feasible at pharmacies.
Self-Management Support Needs From the Perspectives of Persons With Severe Mental Illness: A Systematic Review and Thematic Synthesis of Qualitative Research
Authors: Beentjes Titus A. A. , van Gaal Betsie G. I. , van Achterberg Theo , Goossens Peter J. J.
Published: October 2019

BACKGROUND: The development of de-hospitalization policies in mental health has resulted in a growing emphasis on self-management. In the chronic care model, self-management support is an essential element. Because of the episodic nature of severe mental illness (SMI) and its high relapse rates, we assume that the extent of self-management support needs of individuals with an SMI is considerable. However, a clear overview of the nature of the self-management support needs of persons with SMI is missing. AIMS: This study aimed to identify self-management support needs from the perspective of individuals with SMI. METHOD: A systematic review was conducted using the method of thematic synthesis of qualitative studies. After searching the databases MEDLINE, PsycINFO, CINAHL, and EMBASE, we screened the papers for the eligibility criteria: individuals with an SMI, adequately representing the voice of persons with SMI and describing their self-management support needs. Thirty-one papers were included. RESULTS: The main findings showed that participants in the studies described the need for informational support, emotional support, acknowledgment, encouragement, and guidance to make sense of their illness experiences, ease suffering, obtain validation and recognition, execute self-management tasks, and be led through unfamiliar territory. CONCLUSION: The perspectives of persons with SMI can provide a road map for constructing a self-management support intervention for persons with SMI. Important others have an essential role in fulfilling support needs. Independently managing an SMI is difficult. Therefore, it is preferable to let important others participate in self-management interventions and to introduce peer support.
Investigating Ethics in Sociocultural Literacy Studies
Authors: Collin Ross
Published: October 2019

This conceptual article addresses theories of ethics in literacy studies. Here, ethics means people’s ways of defining, asking about, and living good lives. Although literacy researchers have paid some attention to ethics, they rarely theorize ethics overtly. To demonstrate the need for a clearer concept of the ethical dimension of literacy, this article shows how the author’s earlier study of activists’ literacies was limited by an underdeveloped theory of ethics. The article reviews ideas from recent work in the anthropology of ethics that can draw out and draw together literacy studies’ largely implicit concepts of ethics. Through this discussion, the article presents a clearer theory of the ethical dimension of literacy. The article concludes by using this new theory to study the ethics in the literacy practices of an LGBTQIA activist.
Impact of resistance training sets performed until muscular failure with different loads on intraocular pressure and ocular perfusion pressure
Authors: Vera Jesús , Jiménez Raimundo , Redondo Beatríz , Torrejón Alejandro , de Moraes Carlos Gustavo , García-Ramos Amador
Published: October 2019

Purpose:

The aim of this article is to investigate the acute effects of bench press sets leading to muscular failure with different loads on intraocular pressure and ocular perfusion pressure.

Study design:

A randomized experimental study.

Methods:

Seventeen physically active young men performed four resistance training sets of bench press to muscular failure against different relative loads (65% one-repetition maximum vs 75% one-repetition maximum vs 85% one-repetition maximum vs 95% one-repetition maximum). Intraocular pressure was measured before and immediately after the execution of each of the four sets, and ocular perfusion pressure was also assessed before and after physical effort.

Results:

We found that intraocular pressure increased after reaching muscular failure (p < 0.001, ƞ²= 0.52), being also dependent on the interaction load × point of measure (p < 0.001, ƞ²= 0.33). Our data demonstrated that higher intraocular pressure increases were found when participants performed the bench press exercise against heavier loads, showing statistical significance for the 75% one-repetition maximum (p = 0.020, d = –0.63, mean change = 0.9 mmHg), 85% one-repetition maximum (p = 0.035, d = –0.56, mean change = 1.4 mmHg), and 95% one-repetition maximum (p < 0.001, d = –1.36, mean change = 2.9 mmHg) relative loads. For its part, ocular perfusion pressure showed a reduction after exercise (p = 0.009, ƞ²= 0.35), being these changes independent on the load used.

Conclusion:

Bench press exercise leading to muscular failure provokes an acute intraocular pressure rise, with greater changes when heavier loads are used. Ocular perfusion pressure exhibited an acute reduction after exercise; however, its clinical relevance seems to be insignificant (lower to 4%). We argue that the use of heavy loads, when training to muscular failure, should be discouraged in order to avoid acute intraocular pressure fluctuations. Future studies should corroborate the generalizability of these findings in glaucoma patients.
Preoperative cephalic vein diameter and diabetes do not limit the choice of wrist radio-cephalic arteriovenous fistula
Authors: Hou Guocun , Yan Yonghong , Li Guangyi , Hou Yi , Sun Xiuli , Yin Na , Feng Guozhen
Published: October 2019

Aim:

To identify predictors that affect initial maturation of new wrist radio-cephalic arteriovenous fistula and evaluate the clinical effects of the ipsilateral mid-forearm radio-cephalic arteriovenous fistulas creation in the event of first wrist radio-cephalic arteriovenous fistula failure.

Methods:

We performed a retrospective review of all patients who underwent first wrist radio-cephalic arteriovenous fistula creation between September 2016 and May 2018. Currently, we prefer to re-create an ipsilateral mid-forearm radio-cephalic arteriovenous fistula when the first wrist radio-cephalic arteriovenous fistula fails. Predictors of successful radio-cephalic arteriovenous fistulas were identified using univariate and multivariate analyses. Kaplan–Meier survival analysis and log-rank test were used to calculate successful radio-cephalic arteriovenous fistula rates.

Results:

Univariate analysis showed that predictive factors for successful wrist radio-cephalic arteriovenous fistula include larger preoperative cephalic vein diameter ( p = 0.001) and non-diabetic kidney disease ( p = 0.007). Multivariate binary logistic regression analysis revealed cephalic vein diameter ⩾2 mm (odds ratio = 4.55, 95% confidence interval = (1.49–13.92), p = 0.008) and non-diabetic kidney disease (odds ratio = 4.22, 95% confidence interval = (1.38–12.88), p = 0.011) to be independent predictors for successful radio-cephalic arteriovenous fistula. We re-created ipsilateral mid-forearm radio-cephalic arteriovenous fistulas in 15 patients among the 21 failed wrist radio-cephalic arteriovenous fistulas; all these arteriovenous fistulas maintained clinical maturation following up for 1–2 years.

Conclusion:

Small cephalic vein diameter (<2 mm) and diabetes were independent risk factors for failed wrist radio-cephalic arteriovenous fistulas, but this risk could be overcome by aggressive ipsilateral mid-forearm radio-cephalic arteriovenous fistula to address a failed first attempt. Cephalic vein diameter is more important during the maturation stage, and once maturation has occurred, diabetes has an additive role in determining the patency of wrist radio-cephalic arteriovenous fistula. The “wrist RCAVF first, ipsilateral mid-forearm RCAVF second” strategy is the most clinically significant message of our study.
Same-Day Associations Between Substance Use and Medication Nonadherence Among Persons Living with HIV
Authors: Ramsey Susan E. , Ames Evan G. , Uber Julia , Habib Samia , Clark Seth , Waldrop-Valverde Drenna
Published: October 2019

Objectives:

To examine the same-day associations between substance use and objectively measured antiretroviral therapy (ART) nonadherence among persons living with HIV (PLWH).

Methods:

PLWH ( N = 53) were given an electronic pill box (EPB), and their ART adherence was monitored for 14 days. During a follow-up interview, participants were asked about any alcohol or drug use that occurred during those same 14 days.

Results:

Daily heavy drinking (⩾5 drinks for males and ⩾4 drinks for females) was associated with a nearly five times greater likelihood of same-day ART nonadherence (OR = 4.90, 95% CI = 1.79-13.36, P = .002). Further, drug use was associated with a nearly two times greater likelihood of ART nonadherence on the same day (OR = 1.80, 95% CI = 1.14-2.85, P = .012).

Conclusions:

These results highlight the importance of continuing to pursue interventions to effectively address heavy drinking and drug use among PLWH in order to improve ART adherence.
Robots in tourism: A research agenda for tourism economics
Authors: Ivanov Stanislav , Webster Craig
Published: October 2019

The technological advances in artificial intelligence and robotics allow the massive introduction of service robots by travel, tourism and hospitality companies. While research on service robots in tourism is gaining momentum, the economic aspects of robots’ adoption have been quite neglected. This article critically evaluates the current research on the economic aspects of service robots in tourism and the implications of robots for tourism economics as a field of research in three domains: tourism supply, tourism demand and destination management. In that way, the article delves into the economics of service robots from the perspectives of the tourism companies, the tourists and the destinations as a whole. On the basis of this discussion, the article identifies various research directions and develops specific research questions related to the adoption of robots in tourism that need to be answered by future research in tourism economics.
Mortality and Urological Complications After Open Groin Hernia Repair in Local, General, and Regional Anesthesia: A Nationwide Linked Register Study
Authors: Olsen J. H. H. , Andresen K. , Öberg S. , Mortensen L. Q. , Rosenberg J.
Published: October 2019

Background and Aims:

The choice of anesthesia method may influence mortality and postoperative urological complications after open groin hernia repair. We aimed to investigate the association between type of anesthesia and incidence of urinary retention, urethral stricture, prostate surgery, and 1-year mortality after open groin hernia repair.

Materials and Methods:

Data were linked from the Danish Hernia Database, the national patient register, and the register of causes of death. We investigated data on male adult patients receiving open groin hernia repair from 1999 to 2013 with either local anesthesia, regional anesthesia, or general anesthesia. In relation to the type of anesthesia, we compared mortality and urological complications up to 1 year postoperatively. We adjusted for covariates in a logistic regression assessing urological complications and with the Cox regression assessing mortality.

Results:

We included 113,069 open groin hernia repairs in local anesthesia, regional anesthesia, or general anesthesia. The risk of urinary retention adjusted for covariates was higher after both general anesthesia (adjusted odds ratio = 1.64, 95% confidence interval = 1.05–2.57, p = 0.031) and regional anesthesia (odds ratio = 2.99, 95% confidence interval = 1.67–5.34, p < 0.0005) compared with local anesthesia. The adjusted risk of prostate surgery was also higher for both general anesthesia (odds ratio = 1.58, 95% confidence interval = 1.23–2.03, p < 0.0005) and regional anesthesia (odds ratio = 1.90, 95% confidence interval = 1.40–2.58, p < 0.0005) compared with local anesthesia. Type of anesthesia did not influence 1-year mortality or the risk for urethral stricture.

Conclusion:

Patients undergoing open groin hernia repair in local anesthesia experience the lowest rate of urological complications and have equally low mortality compared with patients undergoing repair in general anesthesia or regional anesthesia.
Individualized Neurofeedback Training May Help Achieve Long-Term Improvement of Working Memory in Children With ADHD
Authors: Dobrakowski Paweł , Łebecka Grażyna
Published: October 2019

Background. Children with attention deficit hyperactivity disorder (ADHD) may suffer from working memory deficits, which can adversely affect their academic performance. Neurofeedback training may enhance working memory and provide a solution to this problem. Aim. To investigate the effect of frequency-neurofeedback on working memory in children with ADHD and to check if the effect is long-lasting. Method. Forty-eight children with ADHD (aged 6-12 years) were randomly assigned either to a neurofeedback with training parameters chosen to take into account each child’s peak alpha frequency (PAF) or to a waiting list control group. Each trained child underwent 19-channel electroencephalography (EEG). All children had average intelligence and none were receiving treatment, such as medications, for ADHD. Prior to the training, MOXO and n-back tests were performed. Next, neurofeedback training sessions with frequency bands for theta and beta ranges determined using each child’s PAF were carried out for 10 weeks. Training parameters were set to increase amplitudes in the low beta range and to decrease amplitudes in the theta and high beta frequency ranges. The n-back test was performed again right after the training and then a year later. Results. During the first n-back test, children from both groups responded correctly to more than 43% of the stimuli. During the second test, children from the waiting list responded correctly to an average of 49% of the stimuli, while children who underwent the neurofeedback training were correct, on average, 69% of the time (significant difference, P < .001). During the third n-back test a year later, children from the waiting list responded correctly to 53% of the stimuli, while those who underwent the neurofeedback training responded correctly to nearly 71%. Conclusion. This study found a statistically significant improvement in a measure of working memory in children who did 10 to 12 sessions of neurofeedback training with training frequency ranges for theta and beta defined according to each child’s PAF. The beneficial effects were still present a year after training.
Desistance From Crime—to What? Exploring Future Aspirations and Their Implications for Processes of Desistance
Authors: Gålnander Robin
Published: October 2019

This article presents findings from a longitudinal interview study following the desistance processes of 10 women. While desistance theory primarily focuses on the processual movement away from crime, this article pays close attention to what desisters strive to desist into. The repeated in-depth interviews reveal a diverse range of future aspirations among desisters, and the analysis unravels gendered, class-, and age-graded aspects of such aspirations. As a result of these findings, the article problematizes parts of previous research both empirically and theoretically, and allows for a development of the understanding of desistance processes.
Cluster randomised trials with different numbers of measurements at baseline and endline: Sample size and optimal allocation
Authors: Copas Andrew J , Hooper Richard
Published: October 2019

Background/Aims:

Published methods for sample size calculation for cluster randomised trials with baseline data are inflexible and primarily assume an equal amount of data collected at baseline and endline, that is, before and after the intervention has been implemented in some clusters. We extend these methods to any amount of baseline and endline data. We explain how to explore sample size for a trial if some baseline data from the trial clusters have already been collected as part of a separate study. Where such data aren’t available, we show how to choose the proportion of data collection devoted to the baseline within the trial, when a particular cluster size or range of cluster sizes is proposed.

Methods:

We provide a design effect given the cluster size and correlation parameters, assuming different participants are assessed at baseline and endline in the same clusters. We show how to produce plots to identify the impact of varying the amount of baseline data accounting for the inevitable uncertainty in the cluster autocorrelation. We illustrate the methodology using an example trial.

Results:

Baseline data provide more power, or allow a greater reduction in trial size, with greater values of the cluster size, intracluster correlation and cluster autocorrelation.

Conclusion:

Investigators should think carefully before collecting baseline data in a cluster randomised trial if this is at the expense of endline data. In some scenarios, this will increase the sample size required to achieve given power and precision.
A Systematic Review and Meta-Analysis of the Association Between Complexity of Emotion Experience and Behavioral Adaptation

Published: October 2019

This article systematically reviews studies investigating the effect of three operationalizations of complexity in emotion experience (i.e., differentiation, covariation, and variability) on situational behavioral adaptation (i.e., physiological, cognitive, and overt action responses), and quantifies the results with meta-analyses. Twenty-seven studies of emotion complexity were identified and divided into four categories: (a) trait and (b) state studies within clinical samples, and (c) trait and (d) state studies within nonclinical samples. Most studies investigated trait emotion differentiation, revealing negligible to small effects ( r range: .06 to .15). Only 4 studies in total assessed indicators of state emotion complexity. The theoretical assumptions behind the indicators of emotion complexity as well as the conceptualization of behavioral adaptiveness are critically discussed, and a number of future avenues for this type of research are proposed.

The discovery of new substances that present innumerable biological activities for the development of drugs is increasingly difficult. Natural marine products are a source of substances with a diversified chemical structure, a broad spectrum of biological activities and low cytotoxicity, which are the essential characteristics for the development of a new drug. An increasing number of reports of Chikungunya virus (CHIKV) infections, in addition to the lack of specific antiviral therapy or vaccines, emphasizes the importance of searching for effective therapy. Studies with the marine green alga Caulerpa racemosa showed antiviral potential. Hence, the aim of this work was to evaluate the anti-CHIKV activity of a marine alkaloid isolated from green alga C. racemosa. Vero cells were used in antiviral assays, submitted to CHIKV, and treated with different concentrations of caulerpin. In the antiviral activity, we observed that the isolated compound showed a much significant and promising EC50 inhibitory effect of 0.8 µM. When evaluating the virucidal activity, we observed that caulerpin was very efficient against CHIKV, being able to inhibit around 90% of the viral infectivity when treated with 5 μM of the compound. We observed that caulerpin added at times 0, 1, 2, and 3 postinfection still maintains a 100% inhibitory potential of viral replication for CHIKV. These studies suggest that the said compounds might be potentially studied for use in the prevention and treatment of CHIKV infections. Derivatives can be considered as a promising new anti-CHIKV drug and can be used for clinical testing.
Engaging with ethics in Internet of Things: Imaginaries in the social milieu of technology developers
Authors: Ustek-Spilda Funda , Powell Alison , Nemorin Selena
Published: October 2019

Discussions about ethics of Big Data often focus on the ethics of data processing: collecting, storing, handling, analysing and sharing data. Data-based systems, however, do not come from nowhere. They are designed and brought into being within social spaces – or social milieu. This paper connects philosophical considerations of individual and collective capacity to enact practical reason to the influence of social spaces. Building a deeper engagement with the social imaginaries of technology development through analysis of two years of fieldwork with start-ups working on Internet of Things, this paper suggests that different action positions can emerge, with consequences for how data is understood and valued. The Disengaged, Pragmatist and Idealist ethical action positions identified in the paper reveal the ways individuals and groups negotiate possibilities for ethical action, through justifications, explanations and structuring of system features.
