Coloniality and the political economy of gender: Edgework in Juárez City
Authors: Gamlin Jennie
Published: April 2021

The manner in which urban locations are drawn into the global economy defines their spatial organisation, distribution and utilisation. The relationships that are generated by this process include economic exchanges, racialised dynamics between workers and owners, gendered divisions of labour and the use and abuse of natural resources and infrastructure. These encounters of globalisation are often unequal or awkward and mediated by varying forms of violence, from structural to interpersonal, as these are used to rebalance the terms on which they meet. Using coloniality as an analytical tool, this article discusses the delicate balance of these Western-led encounters. Globalisation has become colonial by embedding hierarchical relationships in the foundations of the modern political economy. Gender identities, whiteness and non-whiteness, developed and underdeveloped are continually redefined, stigmatising certain groups and locations while elevating others on the basis of colonial power dynamics. Through a case study of the US–Mexico border city of Juárez, this article examines ethnographic work in its global context to explore how shame has become attached to male identities in locations of urban marginality. Theorising around the coloniality of urban space production, I discuss how Juárez’s border location has shaped its development though gendered and racialised frictions that are kept in check with violence. A coloniality perspective enables the unpicking of dominant conceptions of industrial cities in the Global South as metonyms for underdevelopment. Using the concept of edgework, I draw out how violence oils the wheels of globalisation to renegotiate damaged identities in contexts of territorial stigma.
Calculating Theme Parks’ Tourism Demand and Attractiveness Energy: A Reverse Gravity Model and Particle Swarm Optimization
Authors: Zhang Yingsha , Li Xiang (Robert) , Cárdenas David A. , Liu Yu
Published: April 2021

This study proposes two new concepts/indices—tourism demand energy and tourism attractiveness energy—to measure origin-side tourism demand and destination attractiveness. Tourism demand energy and tourism attractiveness energy are estimated based on tourist visitation, travel distance, and visitor flow network relationships. A reverse gravity model was developed, and a particle swarm optimization design was adopted and revised for estimation. This study has a theme park context and uses data collected from 47,360 TripAdvisor reviews for 170 US theme parks. We determined theme park demand energy for each of 52 tourist source regions, and theme park attractiveness energy for each of the 170 theme parks. These two new concepts extend and improve measures of origin-side tourism demand and destination attractiveness. They also underscore the importance of travel distance in measuring origin-side tourism demand and destination attractiveness, offering a new perspective on the driving forces of tourism.
The Effect of Migration on International Tourism Flows: The Role of Linguistic Networks and Common Languages
Authors: Okafor Luke Emeka , Khalid Usman , Burzynska Katarzyna
Published: April 2021

We investigate the effect of migration rates on international tourism flows and whether linguistic networks and common languages affect the relationship between migration rates and tourist flows. We utilize the gravity data set consisting of 166 origin and 30 destination countries, over the 1995–2010 period for the empirical analysis. The results show that increased migration rates lead to higher international tourism flows in destination countries. This effect becomes even stronger when the destination country has a larger linguistic network. Migration matters less, however, when a country-pair shares closer linguistic ties. The findings of this study will help to inform public, and tourism industry policies aimed at boosting sustainable tourism flows, especially post COVID-19 pandemic. Targeted immigration policies, such as those that seek to attract foreign workers with specific skill sets, tend to enlarge linguistic networks and contribute to multilingualism, which in turn can boost international tourism flows.
Evidential Pluralism and Epistemic Reliability in Political Science: Deciphering Contradictions between Process Tracing Methodologies
Authors: Runhardt Rosa W.
Published: April 2021

Evidential pluralism has been used to justify mixed-method research in political science. The combination of methodologies within (qualitative) case study analysis, however, has not received as much attention. This article applies the theory of evidential pluralism to causal inference in the case study method process tracing. I argue that different methodologies for process tracing commit to distinct fundamental theories of causation. I show that, problematically, one methodology may not recognize as genuine knowledge the fundamental claims of the other. By evaluating the epistemic reliability of these fundamental claims, we can find a way out of such conflicts and rescue pluralism.
Evaluating School-Level Student Outcomes of a Systematic Tier 2 Framework
Authors: McDaniel Sara C. , Cohen Daniel , Bruhn Allison L.
Published: April 2021

Targeted Tier 2 interventions are critical to supporting students with challenging behavior and decreasing the resources associated with highly individualized and intense interventions. This study extends findings from recent single-case design studies and case example applications of the Tier 2 Identification and Intervention framework with the first large-scale evaluation of school-level outcomes following district implementation. We employed a pretest–posttest design within one large urban school district ( N = 23,042 students) to evaluate school-level discipline outcomes for elementary schools who received training and coaching on the Tier 2 framework. Fidelity (i.e., Tiered Fidelity Inventory) and school-level demographics (e.g., poverty status, race) were entered as covariates into the generalized linear models. Results indicated statistically significant decreases in office discipline referrals and in-school suspensions for schools with adequate Tier 2 fidelity. Implications, limitations, and future directions are discussed.
Must Good Samaritans vote?
Authors: Brennan Jason , Freiman Christopher
Published: April 2021

The ‘particularity problem’ is one of the most important objections to the putative duty to vote. The problem holds that the reasons usually given on behalf of a duty to vote fail to show there is a duty specifically to vote, but only at best show that voting is one of the many eligible ways to discharge some underlying duty, such as to exercise civic virtue, to contribute to others’ welfare, to avoid free-riding, or to avoid complicity with injustice. For instance, instead of voting for the purpose of avoiding complicity with injustice, one might engage in activism. Julia Maskivker’s recent work represents the most important and significant attempt to overcome this objection since it appeared. She argues, in effect, ‘Why not both?’ She claims that common sense considerations of Good Samaritanism show that most citizens should both vote and perform these other activities. However, in this article, we show that she fails to overcome the particularity problem.
The role of relational dependence, forgiveness and hope on the intention to return with an abusive partner
Authors: Crapolicchio Eleonora , Regalia Camillo , Bernardo Gian Antonio Di , Cinquegrana Vincenza
Published: April 2021

The aim of this study was to examine psychological and relational variables such as dependence, forgiveness (both in their positive and negative dimensions), and hope that may explain why women reconciliate with abusive partners. We administered a questionnaire to women victims of violence. Relational dependence was indirectly associated with greater intentions to return to the violent partner via benevolent forgiveness and hope of a change in the partner. The positive dimension of forgiveness (benevolence) could represent a phase of the cycle of violence, during which the hope for change in the partner can increase the probability of reconciliation.
Identification of a novel homozygous loss-of-function mutation in FUCA1 gene causing severe fucosidosis: A case report
Authors: Zhang Xinwen , Zhao Shaozhi , Liu Hongwei , Wang Xiaoyan , Wang Xiaolei , Du Nan , Liu Hui , Duan Hongfang
Published: April 2021

Fucosidosis is a rare lysosomal storage disorder characterized by deficiency of α-L-fucosidase with an autosomal recessive mode of inheritance. Here, we describe a 4-year-old Chinese boy with signs and symptoms of fucosidosis but his parents were phenotypically normal. Whole exome sequencing (WES) identified a novel homozygous single nucleotide deletion (c.82delG) in the exon 1 of the FUCA1 gene. This mutation will lead to a frameshift which will result in the formation of a truncated FUCA1 protein (p.Val28Cysfs*105) of 132 amino acids approximately one-third the size of the wild type FUCA1 protein (466 amino acids). Both parents were carrying the mutation in a heterozygous state. This study expands the mutational spectrum of the FUCA1 gene associated with fucosidosis and emphasises the benefits of WES for accurate and timely clinical diagnosis of this rare disease.
Investigating Head-On Crash Severity Involving Commercial Motor Vehicles in Kentucky
Authors: Smith James , Hosseinpour Mehdi , Mains Ryan , Hummel Nathanael , Haleem Kirolos
Published: April 2021

This study examines various features affecting the severity associated with commercial motor vehicle (CMV, i.e., large truck and bus) head-on collisions on Kentucky highways. Recent five-year (2015–2019) crash data and variables rarely explored before (e.g., presence of centerline rumble strips, type of passing zone, and terrain type) were collected and prepared using Google Maps. A total of 378 CMV-related head-on collisions were analyzed. The generalized ordered probit (GOP) model was employed to identify the significant factors affecting the severity level resulting from CMV head-on collisions. The model allows the coefficients to vary across the injury severity categories for reliable parameter estimations. From the preliminary investigation, rolling terrains had the highest share of severe CMV head-on crashes (62% and 71% for multilane and two-lane roadways, respectively). The presence of centerline rumble strips could reduce severe crash outcomes along multilane and two-lane facilities. The GOP model identified various significant predictors of minor and severe injuries from CMV head-on crashes. Occupants wearing seatbelt were 39.3% less likely to sustain severe head-on crash injuries. From the roadway characteristics, presence of median cable and concrete barriers could significantly reduce the probability of severe head-on crash injuries, with median cables being more effective. With regard to the driver characteristics, drug impairment and speeding increased the risk of sustaining fatal/serious injuries by 39.5% and 26.4%, respectively. Necessary safety recommendations are proposed to reduce the severity of CMV head-on-related collisions. One example is installing median cable barriers along roadway stretches with a history of head-on CMV-related crashes.
The Matter of Chance: Auditing Web Search Results Related to the 2020 U.S. Presidential Primary Elections Across Six Search Engines
Authors: Urman Aleksandra , Makhortykh Mykola , Ulloa Roberto
Published: April 2021

We examine how six search engines filter and rank information in relation to the queries on the U.S. 2020 presidential primary elections under the default—that is nonpersonalized—conditions. For that, we utilize an algorithmic auditing methodology that uses virtual agents to conduct large-scale analysis of algorithmic information curation in a controlled environment. Specifically, we look at the text search results for “us elections,” “donald trump,” “joe biden,” “bernie sanders” queries on Google, Baidu, Bing, DuckDuckGo, Yahoo, and Yandex, during the 2020 primaries. Our findings indicate substantial differences in the search results between search engines and multiple discrepancies within the results generated for different agents using the same search engine. It highlights that whether users see certain information is decided by chance due to the inherent randomization of search results. We also find that some search engines prioritize different categories of information sources with respect to specific candidates. These observations demonstrate that algorithmic curation of political information can create information inequalities between the search engine users even under nonpersonalized conditions. Such inequalities are particularly troubling considering that search results are highly trusted by the public and can shift the opinions of undecided voters as demonstrated by previous research.
The Rise and Fall of Hydroxychloroquine and Chloroquine in COVID-19
Authors: Aljadeed Rana
Published: April 2021

On March 11th, the World Health Organization (WHO) announced the unprecedented outbreak of “severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2) to be a pandemic. Thus far, COVID-19 has infected over 58,229,138 individuals and caused 1,382,106 deaths worldwide. This has led to the re-purposing of available drugs under “off-label” use—drugs such as hydroxychloroquine and chloroquine. Both drugs have since been evaluated for their ability to treat COVID-19. Here, we summarize recent evidence regarding the use of hydroxychloroquine and chloroquine in hospitalized patients with COVID-19. All data is current as of November 23, 2020.
Robust finite-time trajectory tracking control for a space manipulator with parametric uncertainties and external disturbances
Authors: Yao Qijia
Published: April 2021

Space manipulator is considered as one of the most promising technologies for future space activities owing to its important role in various on-orbit serving missions. In this study, a robust finite-time tracking control method is proposed for the rapid and accurate trajectory tracking control of an attitude-controlled free-flying space manipulator in the presence of parametric uncertainties and external disturbances. First, a baseline finite-time tracking controller is designed to track the desired position of the space manipulator based on the homogeneous method. Then, a finite-time disturbance observer is designed to accurately estimate the lumped uncertainties. Finally, a robust finite-time tracking controller is developed by integrating the baseline finite-time tracking controller with the finite-time disturbance observer. Rigorous theoretical analysis for the global finite-time stability of the whole closed-loop system is provided. The proposed robust finite-time tracking controller has a relatively simple structure and can guarantee the position and velocity tracking errors converge to zero in finite time even subject to lumped uncertainties. To the best of the authors’ knowledge, there are really limited existing controllers can achieve such excellent performance under the same conditions. Numerical simulations illustrate the effectiveness and superiority of the proposed control method.
Near infrared spectroscopy coupled chemometric algorithms for prediction of the antioxidant activity of peanut seed (Arachis hypogaea)
Authors: Bilal Muhammad , Xiaobo Zou , Arslan Muhmmad , Tahir Haroon Elrasheid , Sun Yue , Aadil Rana Muhammad
Published: April 2021

In the present research work, near infrared (NIR) spectroscopy coupled with chemometric algorithms such as partial least-squares (PLS) regression and some effective variable selection algorithms (synergy interval-PLS (Si-PLS), Backward interval-PLS (Bi-PLS), and genetic algorithm-PLS (GA-PLS)) were used for the quantification of antioxidant properties of peanut seed samples including, amongst others, total phenolic content, total flavanoid content and total antioxidant capacity. The developed models were assessed using coefficients of determination for the calibration (R2) and prediction (r2); root mean standard error of cross-validation, RMSECV; root mean square error of prediction, RMSEP and residual predictive deviation, RPD. The efficiency of the developed model was significantly enhanced with the use of Si-PLS, Bi-PLS, and GA-PLS as compared to the classical PLS model. The R2 for calibration and r2 for prediction varied from 0.76 to 0.95 and 0.72 to 0.94, respectively. The obtained results revealed that NIR spectroscopy, coupled with different chemometric algorithms, has the potential to be used for rapid assessment of the antioxidant properties of peanut seed.
Rapid prediction of chemical composition and degree of starch cook of multi-species aquafeeds by near infrared spectroscopy
Authors: Bourne Nicholas , Blyth David , Simon Cedric
Published: April 2021

Ensuring aquafeeds meet the expected nutritional and physical specifications for a species is paramount in research and for the industry. This study aimed to examine the feasibility of predicting the proximate composition and starch gelatinisation (or cook) of aquaculture feeds (aquafeeds) regardless of their intended target species by near infrared (NIR) spectroscopy. Aquafeed samples used for nutrition experiments on various aquatic species with different nutritional requirements, as well as aquafeeds manufactured under varying extrusion conditions and steaming time to generate variable starch cook were used in this study. The various size pellets were ground before scanning by NIR spectroscopy, then models were developed to estimate dry matter, ash, total lipid, crude protein, and gross energy as well as starch cook. Proximate prediction models were successfully produced for diets with R2 values between 0.88 and 0.97 (standard error of cross-validation (SECV) 0.43 to 1.46, residual predictive deviation (RPD) 4.6 to 15.6), while starch cook models were produced with R2 values between 0.91 and 0.97 (SECV 3.60 to 5.76, RPD 1.2 to 1.9). The developed NIR models allow rapid monitoring of the nutritional composition, as well as starch cook, one of the major physical properties of aquafeeds. Models that provide rapid quality control assessment of diet characteristics is highly desirable in aquaculture research and the aquafeed industry.
Management Education in a “Post-Truth” World: Critical Theory’s Contribution to Addressing Disruptions to Learning and Communication
Authors: Welcomer Stephanie A. , Haggerty Mark E. , Sama Linda M.
Published: April 2021

Post-truth poses deep challenges for educators and learners as classrooms are disrupted by the erosion of the status of facts, technologically driven information sourcing, and increasing incivility in the public sphere. These disruptions manifest behaviorally and conceptually and, we argue, can potentially radically realign learning and decision-making landscapes at local classroom levels as well as societal levels, conditioning learners to knowledge systems controlled and curated by powerful interests, threatening students’ ability to function as citizens in a democracy. We analyze these disruptions using the work of Theodor Adorno and Jurgen Habermas and highlight Habermas’s focus on communication and Adorno’s elucidation of cultural production via the culture industry. Using these perspectives, we underline the urgency of responding to post-truth shifts and suggest a framework of practices for educators to consider as they confront these post-truth disruptions.

Authors: Langa Olivia , Cappitelli Alex T. , Ganske Ingrid M.
Published: April 2021

Objective:

This study examines phenotypic presentation and perioperative outcomes of cleft-related procedures for infants with cleft lip and/or palate (CL/P) and prenatal opioid exposure.

Design:

This is a retrospective review of infants with prenatal opioid exposure treated for CL/P from 2008 to 2018.

Setting:

Patients cared for at a tertiary center from 2008 to 2018.

Patients/Participants:

Eighteen patients with documented prenatal opioid exposure and CL/P had primary repairs in our unit.

Main Outcome Measure(s):

The phenotypes of CL/P were characterized. Demographic data regarding additional exposures, as well as associated medical and social comorbidities were recorded. Outcome variables included operative delays, perioperative complications, and loss of follow-up.

Results:

Isolated cleft palate (CP; 67%) was overrepresented among patients with prenatal opioid exposure and CL/P, as was Robin sequence (50% in isolated CP). Fifty-six percent had exposure to additional substances. A majority (67%) had other medical conditions or anomalies, and 17% had known genetic syndromes. Seventy-two percent were in state custody. Thirty-nine percent of exposed patients had delays in their planned operative dates due to medical and/or social factors. There were no postoperative readmissions following cleft procedures. Lack of follow-up was noted in 33% of patients.

Conclusions:

Infants with CL/P who have prenatal opioid exposure are likely to have additional medical conditions and complex social challenges.
From Job Resources to Idea Implementation: A Moderated Sequential Mediation Model
Authors: Massei Fabio , Tierney Pamela , Zappalà Salvatore , González-Romá Vicente
Published: April 2021

Considering the motivational path of the Job Demands-Resources (JD-R) model, this study investigates a multistep process by which contextual job resources might have an indirect effect on idea implementation. Among 187 shop floor employees of a manufacturing company, we found support for a model whereby job control has an indirect effect, over a 5-month time frame, on idea implementation through employee work engagement and personal initiative. In addition, we found that the indirect effect of job control on idea implementation is stronger when employees have a higher conformity orientation. Support was not found for the hypothesized indirect effect of coworker social support on idea implementation. Our findings support the usefulness of the JD-R theory for understanding how increased idea implementation occurs at work, especially when the additional factors of personal initiative and employee conformity orientation are integrated into the model.
Reparative Perineural Hyperplasia in the Gastric Wall: A Histologic Mimic of Perineural Invasion
Authors: Bošnjak Matic , Kojc Nika
Published: April 2021

Reparative perineural hyperplasia is an incidental and probably underreported reactive histologic finding thus far only reported in the setting of healing wounds or adjacent to a dermatofibroma in cutaneous specimens. It is characterized by a focal concentric proliferation of cytologically bland spindled perineurial cells and is hence considered a benign histologic mimic of neoplastic perineural invasion. Thus, it may present a diagnostic pitfall and we therefore consider it as a valuable entity to be aware of. To the best of our knowledge, this brief case report is the first to convey that reparative perineural hyperplasia may also occur in the gastrointestinal tract. It may therefore be a ubiquitous reactive histological phenomenon relating to previous surgical or traumatic wounds in various sites, that is, outside the thus far established setting of skin reexcision specimens.
BCOR-CCNB3 Sarcoma with Prominent Rhabdoid Cells Mimicking Rhabdomyoblasts: Expanding the Morphologic spectrum of BCOR-CCNB3 Sarcoma
Authors: Cai Zhenjian , Duncan Darryl , Li Rongying , Thomas Jaiyeola , Zhu Hui
Published: April 2021

BCOR-CCNB3 sarcoma (BCS) is a rare recently defined undifferentiated sarcoma that predominantly affects children and young adults. The diagnosis of this tumor is difficult due to the highly variable morphology and nonspecific immunophenotype. Emerging data suggest that patients with BCS show response to Ewing sarcoma-based treatment regimen, thus correct diagnosis is of clinical relevance. In this study, we report a case of BCS arising from the big toe of a 15-year-old male patient. The tumor had a prominent population of rhabdoid cells with bright eosinophilic cytoplasm mimicking rhabdomyosarcoma. The tumor cells were focally positive for desmin and myogenin, and negative for CD99. Next-generation sequencing showed the presence of BCOR-CCNB3 gene fusion. BCS with prominent rhabdoid cells has not been described before. This study further expands the morphologic spectrum of BCS.
Can We Stop the Spread of False Information on Vaccination? How Online Comments on Vaccination News Affect Readers’ Credibility Assessments and Sharing Behaviors
Authors: Petit John , Li Cong , Millet Barbara , Ali Khudejah , Sun Ruoyu
Published: April 2021

This study used a 2 (type of news: fake vs. real) × 2 (presence of negative user comments: yes vs. no) × 2 (presence of positive user comments: yes vs. no) between-subjects experimental design to examine the differences in perceived news credibility and sharing intention between fake news and real news on vaccination. Fake news was found to generate a lower level of perceived credibility than real news, which subsequently decreased news sharing intention. Furthermore, negative user comments significantly lowered perceived news credibility, and this was especially true for real news. However, this adverse effect was found to be mitigated by the presence of positive user comments. The experimental results have important theoretical and practical implications for future research on fake news about health and science.
Shiga-Like Toxin Produced by Local Isolates of Escherichia coli O157:H7 Induces Apoptosis of the T47 Breast Cancer Cell Line
Authors: Pinatih Komang Januartha Putra , Suardana I Wayan , Widiasih Dyah Ayu , Suharsono Hamong
Published: April 2021

Purpose:

It has been suggested that Shiga-like toxins produced by Escherichia coli O157:H7 could be used as novel therapeutic agents against malignant tumors. In addition, the antitumor potency of local isolates from Indonesia, which are known to be less toxic than the control isolate ATCC 43894, has not yet been tested. The study aimed to analyze local strains of E. coli O157:H7 as a proapoptosis agent on the T47 breast cancer cell line.

Methods:

As many as 30 culture cells of T47D breast cancer cell line were subjected to purified extracts of Shiga-like toxin originating from 5 local isolates of E. coli O157:H7: KL-48(2), SM-25(1), SM-7(1), DS-21(4), and 1 isolate ATCC 43894 which was used as a control. Toxin production of each isolate was detected using a sandwich enzyme-linked immunosorbent assay, and the treatment of cell lines was observed for 24 hours, with 2 replications; 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide tests and acridine orange/ethidium bromide double staining assays were used for detection and analyses of apoptosis.

Results:

The study showed 2 local strains of E. coli O157:H7 (codes KL-48(2) and SM-25(1)) had toxins positive at titer 5 and 10 μg/100 μL. These titers were lower than the control isolate ATCC 43894, but they had a necrosis effect higher ( P < .05), ie, 80.3%, than control isolate, ie, 63.3%. Other local strain SM-25(1) also had a good necrosis effect. It has a nondifferent necrosis effect ( P > .05) with the control isolate ATCC 43894, ie, 13.0% from 13.3%.

Conclusion:

This study concludes that the Shiga toxin produced by E. coli O157:H7 local isolate (Indonesia) has potential as a proapoptotic and/or necrotic agent for treating T47 breast cancer cell lines, as effectively as ATCC 43894 control isolates.
The effects of supervised versus home Pilates-based core stability training on lower extremity muscle strength and postural sway in people with multiple sclerosis
Authors: Güngör Feray , Tarakci Ela , Özdemir-Acar Zeynep , Soysal Aysun
Published: April 2021

Background:

Pilates-based core stability training (PBCST) is a controlled form of exercise that may improve the transmission of torque from the upper extremities and trunk to the lower extremities by enabling the core muscles to activate effectively.

Objectives:

The aim of this study was to investigate the effects of PBCST given as supervised or home-based on lower extremity strength and postural control in multiple sclerosis.

Methods:

Fifty individuals were enrolled and randomly allocated into two groups. Primary outcome measures were knee muscle strength and postural sway in different conditions. The supervised group received PBCST 2 days per week for 8 weeks at the clinic, and the other group performed PBCST at home. Exercises were progressed every 2 weeks in both groups.

Results:

Between groups, the supervised group was mostly superior to the home group ( p < 0.05). A significant improvement was noted in all parameters in both groups, except some sub-parameters of postural sway in home PBCST ( p < 0.05).

Conclusions:

Supervised PBCST was determined to be more effective than home PBCST in improving strength, postural control, core stability, physical capacity, and fatigue. Although supervised training is the primary choice, home training can be recommended to patients who have limitations attending supervised sessions.
Differential effects of traditional and social media use on COVID-19 preventive behaviors: The mediating role of risk and efficacy perceptions
Authors: Ren Wei , Zhu Xiaowen , Hu Yi
Published: April 2021

The study explored how traditional and social media use produced various cognitive responses toward COVID-19, including perceived severity, susceptibility, and efficacy, and direct and indirect facilitation of COVID-19 preventive behaviors. We tested the hypotheses on data collected from 433 university students in Wuhan, China, using structural equation modeling. We found that traditional media enhanced engagement for preventive behaviors both directly and indirectly by enhancing perceived severity and efficacy, whereas social media showed no impact on preventive behaviors, either directly or indirectly. Furthermore, the direct effect of traditional media on preventive behaviors was markedly stronger than the indirect effect through perceptions.
Queer expectations: An empirical critique of rural LGBT+ narratives
Authors: Conner Christopher T , Okamura Daniel
Published: April 2021

Much of the body of literature on LGBT+ populations within the United States place urban areas and so-called gayborhoods as goals and eventualities, paralleling early US studies on immigration. Using a multistage, mixed-methods approach, consisting of secondary analysis of the Pew 2013 Study of LGBT Persons ( N = 1197) and in-depth interviews (35 gay men, 2 trans-identifying individuals, 1 heterosexual woman, and 2 lesbians), we found that rural LGBT+ residents engaged in both short-term and long-term travel to mitigate feelings of being spatially segregated from the loci of gay social life—what Ghaziani (2019a) refers to as cultural archipelagos. However, rural residents also used their geographical location to resist dominant narratives about LGBT+ life. Some of our respondents felt that living in rural areas better situated them to be activists and advocates for LGBT+ rights, while others simply did not feel they could be comfortable within more urban contexts. These findings suggest that rural LGBT+ residents may have delinked their sexual selves with their cultural and political selves, thus illustrating the plurality of rural queer voices that exists. As we also argue, while residence category should be considered as influencing one’s experience, care must be used to avoid overly deterministic accounts. Finally, this article extends earlier work by Brekhus (2003), Mattson (2015), and Ghaziani (2019a) by presenting the meaningfulness of travel to and from queer cultural strongholds.
Paper trails: Using letter writing to understand social isolation and poverty in a rural community
Authors: Frank Jennifer M , Granruth Laura Brierton , Girvin Heather , Leffler Brittany
Published: April 2021

Letter writing was used as a qualitative research strategy to access the narratives of individuals living in rural poverty. Undergraduate social work students in a freshman seminar course were paired with participants of a local agency to engage in a letter writing exchange about life experiences. Community members who volunteered to participate in the letter-writing exchange were identified via their participation in services offered by a local, community-based agency that is situated in a rural community. In the fall of 2018, a sample of 20 community members and 28 students participated in two rounds of letter exchange.

Findings

The letter-writing exchange was an effective way to collect data. The content of the letters enhanced students’ understanding of the daily experiences of individuals living in rural poverty. Data collected demonstrated that social isolation remains a central concern among poor, rural residents. Letter writing supported a sense of personal connection between students and community members; these social connections may have attenuated the pain of social isolation that many community members experience.

Applications

Narrative inquiry and the use of letter writing as a research methodology allowed us access to greater understanding about the lived experience of rural poverty. People living in rural poverty experience a layered isolation that keeps them separate from resources and each other. Letter writing provided connection and rich data that enhanced our understanding of this community.
Treatment of Diabetic Foot Ulcers With Inforatio Technique to Promote Wound Healing: A Feasibility Trial
Authors: Moeini Sahar , Gottlieb Hans , Jørgensen Tue S. , Larsen Malene R. B. , Brorson Stig
Published: April 2021

Chronic foot ulcers have extensive consequences for diabetic patients’ quality of life and increase risks of amputation and death. The aim of this trial was to assess the feasibility of conducting a larger clinical trial to evaluate the clinical effect of inforatio technique on healing of diabetic foot ulcers (DFUs). Inforatio technique is a novel minimal invasive procedure where small cuts are made on wound beds with punch biopsy tools. This study was a feasibility trial conducted at an outpatient wound care clinic at Zealand University Hospital. Twelve patients with DFUs were included. During a 90-day follow-up, participants visited the clinic 5 times and received inforatio technique twice. Feasibility was assessed with regard to recruitment, acceptability, burden, benefits, protocol adherence, and adverse events. The recruitment rate was 1 patient per eighth day (95% confidence interval [CI] = [4th-13th]), and the retention rate was 100% (95% CI = [74-100]). During follow-up, healing was observed for 4 ulcers (33%, 95% CI = [10-65]) with a mean time for healing of 59 days (range, 22-89) (95% CI = [5-113]). Five ulcers had a reduction of wound area and 3 ulcers had an increase in area from baseline to 90-day follow-up. No temporal relationship was found between inforatio application and wound area increase. There were no patient-reported harmful effects and no adverse events with probable relation to inforatio technique. Patient acceptability and participant adherence were promising. Thus, a larger clinical trial for evaluating the clinical effect of inforatio technique is considered feasible to conduct.
Effects and Safety of Different Silver Preparation in Burns Treatment: A Bayesian Network Meta-analysis
Authors: Kuerban Dilixiati , Maimaiti Maisiwuti , Chen Zhao
Published: April 2021

Silver formulation has been used for external use of burn wounds for several decades, mainly including silver sulfadiazine (SSD), nanosilver dressing (NSD), and silver ion dressing (SID). At present, there is no simultaneous comparison of the effects of silver formulation on burn wounds. The databases were retrieved in an orderly manner from the dates of their establishment to May 2020, including PubMed, the Cochrane Library, Web of Science, and Clinical Trials. Then a network meta-analysis was conducted using R and RevMan 5.1 software. A total of 13 randomized controlled trials (RCTs) involving 945 patients with burns were included. A pairwise meta-analysis of the results was presented: the wound healing time in the SID or NSD treatment group was less than that in the SSD group; and in relieving the pain there was a statistical difference between the SSD, SID, or NSD groups. Network meta-analysis of the results was presented: the wound healing time and relieving the pain in the SID or NSD treatment group were less than that in the SSD group, but there was no statistical difference between the SID and NSD groups. The possibility of NSD in the wound healing time being the best treatment was 75.2%, followed by SID (36.6%), and finally SSD (1.1%); and the possibility of NSD being the best relieving the pain was 83.5%; followed by SID (60.0%), and finally SSD (16.3%). According to the evidence, treatment for burns with NSD can improve the wound healing time and relieve the pain of wounds.

This work presents the characteristics of a solar thermal tower power plant in two different places (Seville and Dubai) using three different HTFs (NaNO3-KNO3, KCl-MgCl2 and Li2CO3-Na2CO3-K2CO3) and three different power cycles (Rankine, sCO2 Recompression and sCO2 Partial cooling cycles). An indirect configuration is considered for the Gemasolar power plant. Detailed modelling is carried out for the conversion of incident power on the heliostat to the output electricity. Optimization of the cycle is carried out to determine the most promising cycle configuration for efficiency. The results showed that for the Gemasolar power plant configuration, the performance of the KCl-MgCl2 based plant was poorest amongst all. NaNO3-KNO3 based plant has shown good performance with the Rankine cycle but plant having Li2CO3-Na2CO3-K2CO3 as HTF was best for all three cycles. Partial cooling was the best performing cycle at both locations with all three HTFs. Placing the Seville Plant in Dubai has improved the efficiency from 23.56% to 24.33%, a capacity factor improvement of 21 and 52 GW additional power is generated. The optimization of the plant in Dubai has shown further improvements. The efficiency is improved, the Capacity factor is increased by 31.2 and 77.8 GW of additional electricity is produced.

Objective

There is a paucity of data regarding six-month readmissions in critical limb ischemia patients and the influence of management strategy during index-admission [endovascular, surgical, hybrid procedure, medical therapy, and amputation]. We aimed to investigate the incidence, predictors, and impact of management strategies on six-month readmission in patients with critical limb ischemia.

Methods

A secondary analysis of the Nationwide Readmissions Database (2016–2017) was conducted. Propensity score matching was performed for subgroup analysis.

Results

We identified 50,058 patients with primary diagnosis of critical limb ischemia. Six-month all-cause and critical limb ischemia-related readmission rate was 52.36% and 10.86%, respectively. The risk of all-cause readmission was lower with amputation but was similar among other subgroups. Patients receiving surgical [HR 0.62, CI(0.48–0.79), p < 0.001] and hybrid procedure [HR 0.65 (0.46–0.93), p = 0.02] had lower risk of unplanned critical limb ischemia-related readmission compared to endovascular, though the risk of unplanned revascularization/amputation during readmission was similar between the three strategies. The risk of non-critical limb ischemia-related readmission was higher with surgical [HR 1.13, CI(1.04–1.23), p = 0.003] and hybrid procedure [HR 1.17, CI(1.08–1.28), p < 0.001], driven by increased procedure-related/wound complications. Eventhough endovascular patients were older with more severe critical limb ischemia presentation, a lower proportion received home-health or placement upon discharge from index-admission. This could account for higher readmission without higher repeat revascularization in endovascular group.

Conclusion

The risk of critical limb ischemia and non-critical limb ischemia-related readmission differ according to the management strategy. Significant differences in discharge disposition exist depending on revascularization strategy. Study findings identify opportunities for reducing readmissions by focusing on nonprocedural aspects like wound-care, discharge planning and placement.
Aroused Argumentation: How the News Exacerbates Motivated Reasoning
Authors: Boyer Ming M.
Published: April 2021

There is increasing evidence that citizens consume the news because it arouses them. However, to explain the motivated processing of news messages, research usually focuses on negative discrete emotions or the valence dimension of affect. This means that the role of arousal is largely overlooked. In this experiment, conducted in 2019 in Austria, I exposed 191 citizens to a televised news item about immigration—varying the level of threat, while taking physiological measures of negative valence and arousal, followed by self-reported indicators of motivated reasoning. The results indicate that combining the valence and arousal dimensions of affect is the preferred way to understand citizens' reactions to political news. While negative affect predicted motivated reasoning, these effects were much more pronounced for those who experienced high arousal at the same time. Not only does this illuminate some of the black box behind motivated reasoning, the consequences for journalism are profound: the way that journalists cover the news might unwittingly drive citizens apart.

Introduction:

Adherence to lifestyle modification in addition to medication adherence is very important in preventing complications. Nevertheless, lifestyle modification guidelines are not widely followed by patients with hypertension. The objective of the study was to explore the predictors of compliance with lifestyle modification among patients with hypertension at Yekatit 12 Hospital Medical College, Addis Ababa, Ethiopia, 2019.

Method:

A descriptive cross-sectional study design was used. A total of 384 patients with hypertension were included in this study. A systematic sampling method was used to select study participants. The data were collected through an interview method by using a structured questionnaire. The data were entered and analyzed using SPSS. Each variable was summarized using summary statistics. To measure the association between lifestyle modification and its predictors, a bivariate and multivariate logistic regression model was used. P-value < 0.05, odds ratio (OR), and 95% confidence interval (CI) were used to determine statistical significance, direction, and strength of association.

Results:

Two hundred six (53.6%) patients with hypertension had poor adherence to the recommended lifestyle modification. Male patients with hypertension were more adherent to lifestyle modification compared with female patients (adjusted OR (AOR) = 0.60, 95% CI: 0.39–0.92). The rate of poor adherence was 1.86 times higher among patients with hypertension diagnosis of <5 years compared with patients with hypertension diagnosis of ⩾5 years(AOR = 1.86, 95% CI: 1.19–2.89). Patients who were adherent to their medication were 2.13 times to have poor adherence to lifestyle modification compared with medication non-adherent patients (AOR = 2.13, 95% CI: 1.38–3.27).

Conclusion:

High proportions of patients with hypertension were non-adherent to lifestyle modification. Sex, age, duration of the disease, and medication adherence were significantly associated with lifestyle modification adherence. Close follow-up of female patients, the elderly, and patients with a short duration of hypertension is recommended.
The first reported cases of meat allergy following tick bites in the UK

Published: April 2021

Allergic reactions frequently involve the production of immunoglobulin E (IgE) antibodies to proteins. However, reactions directed against carbohydrate moieties are increasingly being recognised. Tick bites can contribute to the development of immunoglobulin E to the galactose-1,3-galactose (alpha-gal) moiety on tick salivary proteins. These IgE molecules can cross-react with alpha-gal found in red meats, causing Type I IgE-mediated hypersensitivity reactions to these foods. We present three cases of delayed reactions to beef, pork and lamb in patients with prior tick bites and in the presence of a positive-specific IgE to alpha-gal. Patients were advised to avoid red meat consumption and to carry emergency treatment in the form of anti-histamines with or without adrenaline autoinjector devices. This is the first published report of red meat allergy caused by tick bites suffered in the UK.
Which Type of Interpersonal Interaction Better Facilitates College Student Learning and Development in China: Face-to-Face or Online?
Authors: Yin (尹弘飚) Hongbiao , Shi (史练) Lian
Published: April 2021

Purpose:

This study attempts to explore how Chinese college students engage in face-to-face synchronous and online asynchronous interactions and examine how the two different interaction types are associated with their academic learning (learning achievement and the development of research skills), satisfaction, and their perceptions of learning environments.

Design/Approach/Methods:

A sample of 3,999 undergraduate students from a research university in Northern China participated in the survey. A series of cluster analysis, one-way analysis of variance, and hierarchical multiple regression were conducted.

Findings:

The cluster analysis results revealed that there were four types of learners among these students and that a large percentage of Chinese undergraduates were classified into either digital communicators (36.16%) or passive interactors (32.71%). In general, the face-to-face synchronous interaction generated more desirable academic learning, perceptions of the learning environment, and higher satisfaction than the online asynchronous interaction in most aspects. However, the asynchronous online interaction fostered student autonomy and contributed to students’ completion of an in-depth thesis.

Originality/Value:

By distinguishing face-to-face synchronous versus online asynchronous interactions, this study led to an enhanced knowledge of the interactive patterns of Chinese college students and uncovered the specific effects of the two types of interpersonal interactions in Chinese research universities.
