Influence of a heat-shock pre-treatment on wound-induced phenolic biosynthesis as an alternative strategy towards fresh-cut carrot processing
Authors: Alegria Carla , Gonçalves Elsa M , Moldão-Martins Margarida , Abreu Marta
Published: June 2021

In fresh-cut vegetables, plant tissues are often challenged by (a)biotic stresses that act in combination, and the response to combinatorial stresses differs from that triggered by each individually. Phenolic induction by wounding is a known response contributing to increase products phenolic content. Heat application is a promising treatment in minimal processing, and its interference on the wound-induced response is produce-dependent. In carrot, two-combined stress effects were evaluated: peel removal vs. shredding, and heat application (100 °C/45 s) vs. shredding, on changes in total phenolic content (TPC) during 10 days (5 °C). By applying the first stress combination, a decrease in TPC was verified on day 0 (∼50%), ascribed to the high phenolic content of peels. Recovery of initial fresh carrot levels was achieved after 7 days owing to phenolic biosynthesis induced by shredding. For the second combination, changes in TPC, phenylalanine-ammonia-lyase (PAL), and peroxidase (POD) activity of untreated (Ctr) and heat-treated (HS) peeled shredded carrot samples were evaluated during 10 days. The heat-shock did not suppress phenolic biosynthesis promoted by PAL, although there was a two-day delay in TPC increments. Notwithstanding, phenolic accumulation after 10 days exceeded raw material TPC content. Also, the decrease in POD activity (30%) could influence quality degradation during storage.
The Effectiveness of Transition Care Interventions from Hospital to Home on Rehospitalization in Older Patients with Heart Failure: An Integrative Review
Authors: Suksatan Wanich , Tankumpuan Thitipong
Published: June 2021

Heart failure (HF) is one of the common causes of rehospitalization in older people leading to an increase in the number of mortalities, disabilities, and readmission rates. However, there has been a lack of literature reviews on current evidence regarding the effects of transition care interventions (TCI) on rehospitalization before discharge from hospital to home. The current review aims to examine the effectiveness of transition care interventions on rehospitalization within 30-days for older patients with HF. The current review of international knowledge employs the PRISMA guidelines and includes primary studies published between 2011 and 2021 taken from PubMed, CINAHL, PsycINFO, Cochrane, and Scopus. Our review identified 15 relevant studies that together examined 10,701 patients with HF. We found that the effectiveness of TCIs could reduce rehospitalization rates and costs of care. The findings asserted that nurses, pharmacists, and multidisciplinary teams were predominantly provided transition care interventions. In principle, transition care intervention could inform policymakers to develop the current discharge planning practices in older HF patients. Therefore, interdisciplinary healthcare teams and caregivers should develop the transition care interventions with long-term periods before discharge from hospital to their home, particularly for older patients with HF in order to improve their capacity for self-care, quality of care, and promote continuing care.
“The Master’s Tools Will Never Dismantle the Master’s House”: Ten Critical Lessons for Black and Other Health Equity Researchers of Color
Authors: Bowleg Lisa
Published: June 2021

Audre Lorde’s provocative admonishment, “The master’s tools will never dismantle the master’s house,” is a fitting caution for Black and other scholars of color who seek to use traditional social and behavioral sciences research as a tool to achieve social justice and health equity in Black communities. Invoking Lorde, I use the “master’s tools” as a metaphor for conventional theoretical and methodological approaches and “dismantle the master’s house” as a metaphor for intersectional structures and systems of oppression that created and sustain health inequity in U.S. Black communities. Using a blend of personal narrative and insights from a 23-year career as a Black critical health equity researcher, I share 10 critical lessons for Black and other health equity researchers of color. And because the personal typically reflects the structural, I recommend system and structural-level mitigation strategies for departments, universities, extramural institutions (e.g., journals), and the government, for each critical lesson.
Structural Racism and Immigrant Health in the United States
Authors: Misra Supriya , Kwon Simona C. , Abraído-Lanza Ana F. , Chebli Perla , Trinh-Shevrin Chau , Yi Stella S.
Published: June 2021

Immigration has been historically and contemporarily racialized in the United States. Although each immigrant group has unique histories, current patterns, and specific experiences, racialized immigrant groups such as Latino, Asian, and Arab immigrants all experience health inequities that are not solely due to nativity or years of residence but also influenced by conditional citizenship and subjective sense of belonging or othering. Critical race theory and intersectionality provide a critical lens to consider how structural racism might uniquely impact the health of racialized immigrants, and to understand and intervene on the interlocking systems that shape these shared experiences and health consequences. We build on and synthesize the work of prior scholars to advance how society codifies structural disadvantages for racialized immigrants into governmental and institutional policies and how that affects health via three key pathways that emerged from our review of the literature: (1) formal racialization via immigration policy and citizenship status that curtails access to material and health resources and political and civic participation; (2) informal racialization via disproportionate immigration enforcement and criminalization including ongoing threats of detention and deportation; and (3) intersections with economic exploitation and disinvestment such as labor exploitation and neighborhood disinvestment. We hope this serves as a call to action to change the dominant narratives around immigrant health, provides conceptual and methodological recommendations to advance research, and illuminates the essential role of the public health sector to advocate for changes in other sectors including immigration policy, political rights, law enforcement, labor protections, and neighborhood investment, among others.
Analysis of Latina/o Sociodemographic and Health Data Sets in the United States From 1960 to 2019: Findings Suggest Improvements to Future Data Collection Efforts
Authors: Enid Zambrana Ruth , Amaro Gabriel , Butler Courtney , DuPont-Reyes Melissa , Parra-Medina Deborah
Published: June 2021

Introduction. Prior to 1980, U.S. national demographic and health data collection did not identify individuals of Hispanic/Latina/o heritage as a population group. Post-1990, robust immigration from Latin America (e.g., South America, Central America, Mexico) and subsequent growth in U.S. births, dynamically reconstructed the ethnoracial lines among Latinos from about 20 countries, increasing racial admixture and modifying patterns of health disparities. The increasing racial and class heterogeneity of U.S. Latina/os demands a critical analysis of sociodemographic factors associated with population health disparities. Purposes. To determine the state of available Latina/o population demographic and health data in the United States, assess demographic and health variables and trends from 1960 to the present, and identify current strengths, gaps, and areas of improvement. Method. Analysis of 101 existing data sets that included demographic, socioeconomic, and health characteristics of the U.S. Latina/o population, grouped by three, 20-year intervals: 1960–1979, 1980–1999, and 2000–2019. Results. Increased Latina/o immigration and U.S. births between 1960 and 2019 was associated with increases of Latino population samples in data collection. Findings indicate major gaps in the following four areas: children and youth younger than 18 years, gender and sexual identity, race and mixed-race measures, and immigration factors including nativity and generational status. Conclusions. The analysis of existing ethnoracial Latina/o population data collection efforts provides an opportunity for critical analysis of past trends, future directions in data collection efforts, and an equity lens to guide appropriate community health interventions and policies that will contribute to decreasing health disparities in Latina/o populations.
Testing for Differences in the Reporting of Somatic Symptoms of Depression in Racial/Ethnic Minorities
Authors: Sauceda John A. , Patel Anushka R. , Santiago-Rodriguez Edda I. , Garcia Dellanira , Lechuga Julia
Published: June 2021

We tested if Latinx and Black individuals are more likely to somaticize depression compared with their White counterparts. We analyzed 14,745 depression ratings from 4,101 people living with HIV from 2007 to 2014. We calculated the percentage of each depression score accounted for by somatic symptom items (e.g., feeling tired). We analyzed depression scores using generalized estimation equations, which accounts for repeated measures within each person. Somatic symptoms accounted for 70% of depression scores for White patients, 66% for Latinx patients, and 68% for Black patients. Across the 14,745 assessments, adjusting for age and sex, and within-person correlation, the percentage of the depression scores made up of somatic items was lower for Latinx ( b = −.03, p < .0001) and Black patients ( b = −.02, p < .001), compared with White patients. The idea that Latinx and Black individuals are likely to somaticize depression may lead to underdiagnoses and perpetuate stereotypes and inequities that are not supported by empirical data.
The Long Arm of Oppression: How Structural Stigma Against Marginalized Communities Perpetuates Within-Group Health Disparities
Authors: Mitchell Uchechi A. , Nishida Akemi , Fletcher Faith E. , Molina Yamilé
Published: June 2021

Understanding and addressing health inequities calls for enhanced theoretical and empirical attention to multiple forms of stigma and its influence on health behaviors and health outcomes within marginalized communities. While recent scholarship highlights the role of structural stigma on between-group health disparities, the extant literature has yet to elucidate the mechanisms through which structural stigma gives rise to within-group health disparities. In this article, we review and use relevant literature to inform the development of a conceptual model outlining how structural stigma contributes to within-group health disparities by creating division and tension within communities marginalized due to their social statuses and identities. We specifically focus on disparities among (1) communities of color due to White supremacy, (2) gender and sexual minority communities due to patriarchy and heterosexism, and (3) the disability community due to ableism. We argue that the nature and extent of the stigma members of stigmatized communities face are intricately tied to how visible the stigmatized characteristic is to others. By visibility, we refer to characteristics that are more easily perceived by others, and reveal a person’s social identity (e.g., race/ethnicity, nativity, relationship status, gender expression, and disability status). This paper advances the literature by discussing the implications of the model for future research, practice, and policy, including the importance of acknowledging the ways in which structural stigma intentionally disrupts the collective identity and solidarity of communities and consequently threatens health equity.
Racial and Sexual Minority Scholar Positionality: Advancing Health Status and Life Opportunity Among Sexual Minority Men of Color
Authors: Keene Lance , Guilamo-Ramos Vincent
Published: June 2021

Black and Latino sexual minority men (BLSMM) scholars are well positioned to draw on their unique perspectives and expertise to address the health status and life opportunities (HSLO) of BLSMM. Increasingly, research related to the positionality of scholars of color suggests that the scholar’s stance in relation to the community being researched has important implications for the research. Despite growing recognition of the importance of scholar positionality, limited attention has been paid to the relationship between scholar-of-color positionality and improving HSLO trajectories of BLSMM. Furthermore, extant literature fails to specify the mechanisms by which scholar-of-color positionality can improve HSLO among BLSMM. This article seeks to fill this gap in research by arguing that an inadequate consideration of scholar positionality in health and life opportunity research has important implications for the HSLO of BLSMM. A multilevel, mediational model addressing factors at the micro-level (i.e., intrapersonal resources)—BLSMM scholars’ personal commitments to BLSMM communities, cultural knowledge and expertise, and shared life experiences; meso-level (i.e., scholar and affected community interactions)—historical membership, mutual interdependency and trust, and community and organizational gatekeeping; and macro-level (i.e., national policies and priorities regarding BLSMM)—national priorities regarding the health and social welfare of BLSMM, allocation of BLSMM research and program funding, societal sentiment, and national investment in the workforce development of BLSMM scholars and clinicians are detailed. In conclusion, we identify recommendations and strategies for advancing scientific, programmatic, and policy efforts, aimed at improving HSLO among communities of BLSMM.
Feline ureteral obstruction: a case-control study of risk factors (2016–2019)
Authors: Kennedy Alexandra J , White Joanna D
Published: June 2021

Objectives

Ureteral obstruction (UO) in cats causes acute kidney injury and typically requires surgical intervention. Information is required about potentially modifiable risk factors to inform prevention strategies.

Methods

A case-control study was performed to assess risk factors associated with feline UO. Cases were defined as cats with either of the following: (1) ureteral obstruction (ureteroliths: 13/18; unknown: 5/18) confirmed with pyelography; or (2) a creatinine concentration >140 µmol/l with both UO (ureteroliths: 6/10; blood clots: 3/10; pyonephrosis: 1/10) and pyelectasia ⩾5 mm on abdominal ultra sonography. Controls were defined as cats without evidence of UO on history, physical examination and abdominal ultrasound. Age, sex, breed (domestic shorthair/longhair), diet (predominantly dry, mixed or predominantly moist food), housing (indoors or mixed) and plasma total calcium were evaluated for their association with UO using multivariable logistic regression. A receiver operator characteristic (ROC) curve was created to evaluate the predictive ability of the final model.

Results

In total, 168 cats (28 cases, 140 controls) were included. Age, sex, breed, housing and total calcium were not significantly associated with UO; however, diet was. Compared with cats eating a predominantly moist food diet, cats fed a predominantly dry food diet were 15.9 times more likely to develop a UO (95% confidence interval 2.9–295; P = 0.009). There was no difference in the association between diet and UO in cats fed a mixed diet vs cats fed a predominantly moist food diet ( P = 0.25). The area under the ROC curve was 72%.

Conclusions and relevance

Changes in diet formulation could provide a simple and economical method to reduce the risk of UO.
Comparison of total keratometry with corneal power measured by optical low-coherence reflectometry and placido-dual Scheimpflug system
Authors: Kommineni Usha Bhanu , Mohamed Ashik , Vaddavalli Pravin K , Reddy Jagadesh C
Published: June 2021

Purpose:

To compare the total keratometry (TK) and astigmatism measurements in eyes with cataract using automated keratometry of swept-source optical coherence tomography (ss-OCT), optical low-coherence reflectometry (OLCR), simulated keratometry (SimK), and total corneal power (TCP) of combined placido-dual Scheimpflug imaging system.

Setting:

The study was conducted at LV Prasad Eye Institute, Hyderabad, India.

Design:

Retrospective evaluation of electronic medical records of patients who were evaluated for cataract surgery

Methods:

Twenty-eight eyes of 28 patients were included in the study. All patients evaluated for cataract surgery underwent corneal power measurements using three devices: ssOCT, OLCR, and combined placido-dual Scheimpflug imaging were included in the study. Vector analysis was performed to evaluate corneal astigmatism and Bland-Altman analysis was conducted to evaluate the limits of agreement of similar parameters among devices.

Results:

The mean TK was statistically significantly different from the keratometry obtained from optical biometers and values measured by the Scheimpflug imaging system. The magnitude of mean difference was greater between TK and TCP (0.75 ± 0.25) compared to other variables. The mean difference in astigmatism between TK, ss-OCT-K (0.09 ± 0.12, p = 0.48), OCLR-K (0.10 ± 0.48, p = 0.91), and TCP (0.09 ± 0.47, p = 0.31) was not statistically significant but was statistically significant between TK and SimK values (0.23D ± 0.49D). The axis of orientation (<20°) of astigmatism was comparable (100%, 28 eyes) between two keratometry variables measured by ss-OCT.

Conclusion:

There appears to be a greater correlation of automated keratometry, and TK values obtained from ss-OCT compared to other variables studied. The measurements from TK, Simk, and TCP cannot be used interchangeably.
Protected but not from Contamination: Antimicrobial Resistance Profiles of Bacteria from Birds in a Ghanaian Forest Protected Area

Published: June 2021

Resistance to antimicrobial agents is a growing concern in public health. It has been reported in wildlife from several places in the world though wild animals are not normally exposed to clinically used antimicrobial agents. Despite this, very little research has been done in Ghana to determine antimicrobial resistance in wild animals, particularly those in protected areas. In this study, the presence of colistin resistant and multidrug resistant (MDR) gram-negative bacteria in cloacal swabs of wild birds captured in a Ghanaian forest protected area were evaluated. A total of 195 isolates from 138 individual birds were obtained, identified and tested for resistance to colistin. The colistin-resistant isolates were subsequently tested for multidrug resistance to 4 other antimicrobial agents (Oxytetracycline, Streptomycin, Ampicillin and Ciprofloxacin). Colistin resistance was observed in 6.5% (9/138) of the birds and this was seen in only birds that were sampled close to the reception area of the protected area. About 50% of the colistin-resistant isolates were multidrug resistant. AMR isolates were obtained from birds that have been documented to show an insectivorous or omnivorous feeding preference. Data obtained from the study suggests that AMR and MDR occurred in wild birds from the Conservation Area and supports the claim that proximity to human impacted habitats (settlements/farmlands) increased the likelihood of carriage of AMR. Though the routes of transmission remain unclear, there is potential for spread from the wild birds to other wild/domestic animals and possibly back to humans.
Which national park attributes attract international tourists? A Sri Lankan case study
Authors: Suresh Kanesh , Wilson Clevo , Quayle Annette , Khanal Uttam , Managi Shunsuke
Published: June 2021

This study assesses how and in what circumstances tourists’ perceived value of nature-based tourism (NBT) attributes differ among various types of national parks. A novel discrete choice experiment is used employing data collected from 343 international tourists in four national parks in Sri Lanka. We find that the improvements in frequency of large species’ encounters, habitat quality and proximity to encountered wildlife produce greater utility. A surprising finding is that tourists are shown to prefer to spend only a limited amount of time at national parks. They also tend to choose less-visited parks that have large mammals for which they would be willing to pay more compared to those national parks that are more frequently visited. Our article contributes to the empirical evidence that time is a key factor that determines the tourism destination choice and less-visited parks offer considerable potential for future growth of tourism.
Leader-parent relationships in the early childhood education context: An exploration of testimonial and epistemic justice
Authors: Adams Shirley Eileen , Myran Steve
Published: June 2021

Countries around the world have increased their focus on high quality early childhood programing. Recognizing the importance of parental and community engagement as a lever for improving child development and learning outcomes, and as a means of addressing social justice challenges, the Organization for Economic Cooperation and Development (OECD) (2018) has emphasized the need for more research on the complex dynamics between structure, process, learning, and development. Such research should consider the impacts of the dominant neo-managerial paradigm and its overemphasis on clearly defined linear cause and effect pathways between structure and student learning, which underrepresents the reciprocal role that parents, the community and the students themselves play in shaping the learning setting (Myran & Sutherland, 2019a). Students’ and families’ senses of belonging to the community of knowers have major implications for their motivation, sense of ownership and buy-in (Davis, 2006; Goodenow & Grady, 1993). This study explored the lived experiences of parents/guardians of young children with the leadership of their children’s early childhood education program and how these individual and social interactions shaped parents’ epistemic agency, and their access to rhetorical spaces that recognized them as credible knowers. Utilizing a phenomenological approach, we conducted in-depth interviews with 20 parents whose children attended publicly funded pre-school programs. Findings revealed limited communication with leadership and difficulty developing positive relationships. Moreover, these challenges limited their access to rhetorical spaces to be heard and recognized as credible knowers. This study offers one small window into the OECD’s (2018) call for more research on the dynamics between structure, process, learning and development, and the importance of the quality of parental and community engagement as a lever for enhancing healthy child development and learning, and as a means of more effectively addressing ongoing social justice challenges.
Nation branding through the lens of soccer: Using a sports nation branding framework to explore the case of China
Authors: Li Xiufang (Leah) , Feng Juan
Published: June 2021

Soccer is seen as an extended instrument to brand China in the post-Beijing Olympic period. This article explores how the brand of China is expressed and negotiated through the lens of soccer by adopting the content analysis method to deconstruct the media texts specific to sports mega-events. The findings show the creation of a number of media frames accompanied by a new tradition in the representation of Chinese national identity, featuring the rhetoric of a ‘powerful’ nation and social prosperity attributed to the projected common goal of elevating China to be a world soccer superpower by 2050. These media frames provide insights into the underlying personalities of the country’s brand, including humiliation, world hegemony, trust and superiority. We argue that the merit of nation branding in China is more engaged with the inwardly oriented political exercise aiming at restructuring national identity for the purpose of consolidating the state’s legitimacy and social cohesion. The proposed sports nation branding framework expands the scope of critical research on nation branding within the context of identity politics in relation to sports. It underlines the significance of strengthening the personality traits of a nation’s brand through developing a thriving soccer culture. Due to the growing importance of soccer in East Asia, this article has both domestic and regional significance.
Expat anxieties: Risk and safety in Cape Town, South Africa and Santiago de Chile
Authors: Falkof Nicky
Published: June 2021

This article considers ‘expatriate’ discourses about security in Cape Town, South Africa and Santiago de Chile. The cities themselves have reputations as desirable, beautiful, civilised, modern and welcoming, in contrast to lurid ideas about poverty, crime, filth and corruption that often characterise northern imaginings of the developing world. Yet, their locations within sub-Saharan Africa and Latin America, respectively, nonetheless mark them out as potential spaces of high risk for migrants from the north. In this article, I am interested in the way in which lifestyle migrants to these cities negotiate fears about risk and safety within their new homes. In order to consider this question, I discuss posts on the online messageboards dedicated to these two cities within the popular InterNations ‘expat forum,’ as well as a series of interviews with people who use the forum. I use these respondents’ discursive constructions of safety, threat, otherness, belonging and the unknowability of the global south city to consider some of the affective underpinnings of this form of privileged migration.
The nation as an imagined commodity: Branding ‘Melania’
Authors: Pušnik Maruša , Jontes Dejan
Published: June 2021

The article uses the case of Melania Trump, the former First Lady of the United States, to analyse the discursive strategies through which the print media in Slovenia represented ‘Melania’ as an ethnically born Slovenian on a national scale. The article also demonstrates how patriotism, based on the love and feelings of belonging to the Slovenian nation-state, was nationalized in the case of ‘Melania’. The main argument is that numerous and repetitive media representations of ‘Melania’ aggressively put nationalism in the commercial context, and consequently transformed the nation into a commodity and an object of trade which can be sold and of which the Slovenians can make a profit. Consequently, the Slovenian press coverage of Melania Trump created her as a national brand meant to perform on the local, national market when merging emotional attitudes with commercial allure. The article concludes with the discursive strategies such as representing ‘Melania’ as ‘ours’, as a tool to accelerate the country’s economic growth and as a branding strategy to sell the Slovenian landscape and culture and produce the Slovenian nation as an imagined commodity. Furthermore, such branding of the nation is directed towards domestic rather than international audiences.
Social protection responses to COVID-19 in Africa
Authors: Devereux Stephen
Published: June 2021

Most African countries implemented measures to contain the spread of COVID-19 during 2020, such as restrictions on business activity and travel, school closures and stay-at-home lockdowns for several months. These restrictive policies had adverse economic and social consequences that triggered a follow-up wave of expansionist public interventions intended to mitigate these effects. ‘Shock-responsive’ social protection measures included increased benefits to existing beneficiaries (vertical expansion) and registration of new beneficiaries on existing programmes (horizontal expansion). These approaches had the advantages of being quick and administratively simple, but the disadvantage of bypassing people who were made most vulnerable by COVID-19, notably retrenched and informal workers with no access to social insurance. On the other hand, setting up new humanitarian relief or temporary social assistance programmes was slow and susceptible to targeting errors and corruption. COVID-19 also prompted a reassessment of the social contract regarding social protection, with some governments recognising that they need to become better coordinated, more inclusive and rights-based.
Reframing temporality in participatory visual research with timelapse video
Authors: Monea Bethany , Stornaiuolo Amy , Plummer Catena Emily
Published: June 2021

In this article, the authors offer ‘timelapse’—removing frames from video footage to effectively ‘speed up’ visual activity—as an experimental method for engaging in the practice of seeing the emergence and contingency of activity across different timescales and in collaboration with participants. Building on previous calls to zoom up and out in analysis in order to understand the cumulative impact of moments, events, and episodes across different timescales, this article frames timelapse video as a means of visually representing activity in a way that emphasizes not only its multimodal dimensions but its temporal ones. The authors explicate how the ‘zoomed out’ temporal perspective of timelapse video offers two intertwined analytic affordances in qualitative research: (1) insight into how activity is coordinated across micro-, meso-, and macro-timescales, and (2) insight into how activity is emergent from and contingent upon macrosocial factors. They argue that these analytic affordances of timelapse are particularly well suited to being collaboratively realized alongside participants, illustrating these participatory affordances through data collected from a two-year study about literacy and arts-based practices in a US public high school. This article suggests that the participatory practice of seeing what circulates across different scales of time in timelapse video not only highlights the contingency and partiality inherent in all visual representations, thus unsettling notions of video as depicting ‘reality’ or ‘truth’, but also emphasizes the importance of multiscalar perspective taking for considering how macrosocial dimensions of meaning unfold across longer timescales and in relation to micro-interactional ones.
The flash of a van: A cartography of a mobile educational initiative in the Claymore district of Sydney
Authors: Cole David R. , Moustakim Mohamed
Published: June 2021

Modern cities produce areas of poverty, despite their overall wealth. These pockets of living can exacerbate societal problems, especially because the opposite end of the societal spectrum is often close by. This paper examines an educational initiative in one such district, called Claymore, in the suburbs of outer Sydney. The project deployed a mobile youth van equipped with high-tech educational hardware and software, and encouraged local youth to take advantage of the van, to further high-tech skills acquisition. This paper offers a Deleuze/Guattari (1988) cartographic approach to mapping the effects of the van extracted from their opus maxima, 1000 Plateaus. This approach is a mode of social topology that deepens the type of discourse analysis that one may take from Foucault and its uses in educational research (e.g., Ball, 2012). The social cartography that one might derive from Deleuze/Guattari involves producing a ‘plane of immanence’ and assemblages about the phenomena under scrutiny, in the case of this article, the mobile van initiative in Claymore. This does not mean that hierarchies are diminished, but that they are reset for the purposes of analysis, so that their complex relationships are realized and understood. This paper looks to describe and analyse what is immanent to the situation in Claymore, and what effects the mobile van might have given this state of affairs.
The effect of clay organophilization on wood plastic composite (WPC) based on recycled high density polyethylene (HDPE) and coir fiber

Published: June 2021

One way to optimize composite mechanical properties is through hybridization with small amounts of reinforcing fillers. Thus, this study investigates the effect of incorporation of 3 wt% of clay (BT) and organoclay (OBT) on the properties of a recycled wood plastic composite (WPC) based on HDPE and 20 wt% of coir fiber compounded with 5 wt% of maleic anhydride-grafted polypropylene (PP-g-MA), as coupling agent, and 5 wt% of Struktol TPW 113, as lubricating agent. Raw materials were characterized by X-ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Coir fiber was characterized by optical microscopy and TGA. Wood plastic formulations (with clay and organoclay) were prepared in an internal mixer coupled to a torque rheometer operating at 190°C, 60 rpm for 10 min. Then, the mixtures were compression molded. Formulations were characterized by SEM, TGA, DSC, tensile and water absorption tests. FTIR analysis showed the characteristic bands of organophilic clay. XRD showed an increment in the interplanar distance of the clay, after the incorporation of quaternary ammonium salt (distearyl dimethyl ammonium chloride, Praepagen® WB), confirming the organoclay formation. Organophilization decreases the clay hydrophilic character and reduces the water uptake of WPC-BT. Despite the fact that BT incorporation led to WPC nanocomposite with intercalated structure, this WPC-clay composition did not show a significant increase in tensile strength and elongation at break. The poor interfacial adhesion between the raw materials and the polymer matrix, the low aspect ratio provided by coir fibers and also, the partially intercalated structure of composites have contributed to this behavior.
Incidence and Treatment Efficacy of Trigger Finger in the Breast Cancer Population on Aromatase Inhibitors
Authors: Regent-Smith Andrew J. , Childers Evan J. , Dzwierzynski William W. , Morgan Aaron L.
Published: June 2021

Background

Trigger finger is a common hand complaint of the general population. Limited literature exists implicating a low-estrogen state in patients on aromatase inhibitor (AI) therapy for breast cancer who develop trigger finger. The authors’ objective was to determine the incidence and treatment outcomes of this population.

Methods

A single-center retrospective chart review was conducted on patients with a diagnosis of breast cancer on AI who developed trigger finger from 2010 to 2019. The total population of patients during this time served as our population, and patients with breast cancer not on AI with trigger finger served as our control. Primary outcomes included total number of injections and need for surgery. Secondary outcomes included risk factors for surgery. χ2 analysis and logistical regression model determined the significance of primary and secondary outcomes, respectively.

Results

In all, 192 patients of a population size of 664 751 met our study group criteria. The study group showed a higher incidence of trigger finger (5.1% vs 1.3%; P < .001) compared with our population. Patients treated with AI for breast cancer had both higher incidence of trigger finger (5.1% vs 1.5%, P < .001) and injections (77.1% vs 66.5%, P < .001) compared with patients not on AI therapy. Independent risk factors requiring surgical treatment were found in patients with diabetes (odds ratio [OR], 3.54; P = .01) and in patients with concomitant radiation therapy (OR, 3.17; P = .02).

Conclusions

This study demonstrates for the first time the incidence, treatment outcomes, and surgical risk factors of trigger finger in patients on AI therapy for breast cancer.
A phenomenological inquiry into the influence of crucible experiences on the leadership development of Black women in higher education senior leadership
Authors: Chance Nuchelle L
Published: June 2021

Supported by the Crucibles of Leadership theory, this article explores how adverse experiences influence the leadership development of Black women in higher education senior leadership. I use phenomenology to explore how these leaders’ adverse lived experiences manifested as transformative crucible experiences with resilience, thus promoting leadership development. Black people have been continuously subject to adversity, while Black women have overcome the compounded adversities resulting from their intersectional identities. Reported lived adversities included physical, sexual, and verbal assault and abuse, adverse childhood experiences such as growing up in poverty, being raised by single parents, being subject to bullying, losing loved ones, discrimination, and health issues. Black women are resilient, and education has proven to be a lifeline regarding adversity, thus promoting leadership capabilities. They use adversity as fuel to overcome adverse crucible experiences, thus developing the necessary skills to prepare them for leadership. The results further reveal that Black women in higher education senior leadership experienced significant adverse experiences that manifested as crucible experiences by overcoming adversity. The findings reveal an association between their ability to develop the necessary leadership skills to advance their career and their lived adverse experiences.

Published: June 2021

Background

Rotator cuff tears (RCTs) are often associated with severe shoulder pain. Non-steroidal anti-inflammatory drugs, not recommended for long-term use, do not effectively manage RCT-induced pain, resulting in reduced quality of life. To improve management, a better understanding of the fundamental properties of RCT pain is needed. Here, we aimed to compare the expression levels of nerve growth factor (NGF) and cyclooxygenase-2 (COX-2) mRNA in the synovial tissues of patients with RCT-induced pain and patients with non-painful recurrent shoulder dislocation (RSD).

Methods

The study included 32 patients with RCT who underwent arthroscopic rotator cuff repair and 28 patients with non-painful RSD who underwent arthroscopic Bankart repair. Synovial tissue samples were harvested from subacromial bursa and rotator interval of RCT patients and from the rotator interval of RSD patients. Samples were analyzed quantitatively expression levels for NGF and COX2 mRNA and NGF protein.

Results

NGF mRNA and protein levels were significantly higher in the rotator interval of RCT patients than in the rotator interval of RSD patients ( p = 0.0017, p = 0.012, respectively), while COX2 mRNA levels did not differ significantly between the two patient groups. In RCT patients, COX2 mRNA was more highly expressed in the rotator interval than in the subacromial bursa ( p = 0.038), whereas the mRNA and protein levels of NGF did not differ between the two tissues. The expression of NGF mRNA in the synovium of the rotator interval was significantly correlated with the numeric rating scale of pain (ρ = 0.38, p = 0.004).

Conclusion

NGF mRNA and protein levels were elevated in patients with painful RCT compared with those in patients with non-painful RSD, whereas COX-2 levels were comparable in the two patient groups. These findings provide insights into novel potential strategies for clinical management of RCT.
Optimal interception strategy of air defence missile system considering multiple targets and phases

Due to the rapid development and wide application of air attack weapons, air defence missiles against them are increasingly important and have become the main air defence weapons in modern war. However, interception strategy of air defence missile system is ignored in previous studies. Thus, using the combinatorial optimization, this paper proposes a methodology to optimize the strategy of ADMS in a missile-target interception process in order to minimize the expected costs for defender. According to the practice, the considered process has multiple targets and multiple phases, and the expected costs are composed of the loss caused by targets and the cost for intercept missiles. Two numerical examples are presented to illustrate the proposed methodology. The results of the examples show that interception strategies have a great impact on the expected costs of ADMS during a missile-target interception process.
Generation Z’s screen culture: Understanding younger users’ behaviour in the television streaming age – The case of post-crisis Greece

Post-crisis Greece is experiencing dynamic audiovisual market growth, faster than the EU average. As Greek TV responds to the challenges of the streaming era, new paths are forged by young viewers/users. This article, based on a survey of nearly 1,000 students, attempts to characterise the viewing patterns of young audiences, who are early adopters and heavy consumers of streaming television. We argue that whereas young Greek media users favour streaming platforms, they value the social character of traditional television, which plays a prominent role in post-crisis Greece. Young media users’ screen behaviour can be described as mobility-centred and algorithmically naïve.
Co-creating content with children to avoid ‘Uncle Swag’: Strategies for producing public service television drama for tweens and teens at the Danish children’s channel DR Ultra

Published: June 2021

This article explores the strategies for fictional content of the Danish children’s channel DR Ultra through a qualitative case study of the production framework behind its successful series Klassen (2016–now). Building on studies of television production and theories of co-creation, the analysis investigates the use of co-creative initiatives during the development and writing as well as the production of programmes. The analysis highlights the value of involving children more closely in content targeting them, not only to ensure that what is told and how it is told is relevant and appealing, but also to create a sense of participation and co-creation.
‘Shoulda, Coulda, Woulda’: Young Swiss audiences’ attitudes, expectations and evaluations of audiovisual news and information content and the implications for public service television

Published: June 2021

Public service media (PSM) are still seen in most European countries as a core means of informing citizens of all ages. Nevertheless, PSM struggle to reach young audiences, who are often characterised as news-avoidant or news-deprived. This article asks what meaning the news and information offered by PSM have for young people. The qualitative study describes young people’s attitudes and expectations regarding audiovisual news and information content through observation of their media usage habits in an experimental setting. It provides insights regarding how young people find and select news in today’s digital media environment and highlights opportunities for PSM providers to reach and engage with young audiences more effectively.
Variability of environmental sound levels: An observational study from a general adult intensive care unit in the UK
Authors: Darbyshire Julie L , Duncan Young J
Published: June 2021

Background

Intensive care units are significantly louder than WHO guidelines recommend. Patients are disturbed by activities around them and frequently report disrupted sleep. This can lead to slower recovery and long-term health problems. Environmental sound levels are usually reported as LAeq24, a single daily value that reflects mean sound levels over the previous 24-h period. This may not be the most appropriate measure for intensive care units (ICUs) and other similar areas. Humans experience sound in context, and disturbance will vary according to both the individual and acoustic features of the ambient sounds. Loudness is one of a number of measures that approximate the human perception of sound, taking into account tone, duration, and frequency, as well as volume. Typically sounds with higher frequencies, such as alarms, are perceived as louder and more disturbing.

Methods

Sound level data were collected from a single NHS Trust hospital general adult intensive care unit between October 2016 and May 2018. Summary data (mean sound levels (LAeq) and corresponding Zwicker calculated loudness values) were subsequently analysed by minute, hour, and day.

Results

The overall mean LAeq24 across the study duration was 47.4 dBA. This varied by microphone location. We identified a clear pattern to sound level fluctuations across the 24-h period. Weekends were significantly quieter than weekdays in statistical terms but this reduction of 0.2 dB is not detectable by human hearing. Peak loudness values over 90 dB were recorded every hour.

Conclusions

Perception of sound is sensitive to the environment and individual characteristics and sound levels in the ICU are location specific. This has implications for routine environmental monitoring practices. Peak loudness values are consistently between 90 and 100 dB. These may be driven by alarms and other sudden high-frequency sounds, leading to more disturbance than LAeq24 sound levels suggest. Addressing sounds with high loudness values may improve the ICU environment more than an overall reduction in the 24-h mean decibel value.

Lunate reconstruction using a lateral femoral trochlea osteochondral graft was carried out in 27 patients with Stage III Kienböck’s disease from 2012 to 2019. Twenty-three of these patients could be followed-up in this retrospective study. Ten were women and 13 men. Nine were Lichtman Stage IIIA, seven Stage IIIB and seven Stage IIIC. The mean follow-up was 39 months (range 12–86). Bony consolidation was found in 18 of the 23 patients, with no graft loss. The mean Disabilities of the Arm, Shoulder and Hand score (DASH score) was 11 and the Modified Mayo Wrist Score was 83. There were only two radiological deteriorations, with the same or improved Lichtman classifications in the other patients and a significant reduction in pain. Postoperative extension of the wrist (52°) and flexion (48°) were comparable with preoperative values and, respectively, 81% and 72% of the contralateral side. Grip strength and pinch grip were 32 kg and 12 kg, 88% and 94% of the other hand, respectively, and an insignificant increase compared with the preoperative values. The vascularized lateral femoral trochlea osteochondral graft yields good short- and mid-term results in Grade III Kienböck’s disease.
