Published: July 2022

Background:

The COVID-19 pandemic has caused millions of deaths worldwide, leading to symptoms of grief among the bereaved. Neither the burden of severe grief nor its predictors are fully known within the context of the pandemic.

Aim:

To determine the prevalence and predictors of severe grief in family members who were bereaved early in the COVID-19 pandemic.

Design:

Prospective, matched cohort study.

Setting/Participants:

Family members of people who died in an acute hospital in Ottawa, Canada between November 1, 2019 and August 31, 2020. We matched relatives of patients who died of COVID (COVID +ve) with those who died of non-COVID illness either during wave 1 of the pandemic (COVID −ve) or immediately prior to its onset (pre-COVID). We abstracted decedents’ medical records, contacted family members >6 months post loss, and assessed grief symptoms using the Inventory of Complicated Grief-revised.

Results:

We abstracted data for 425 decedents (85 COVID +ve, 170 COVID −ve, and 170 pre-COVID), and 110 of 165 contacted family members (67%) consented to participate. Pre-COVID family members were physically present more in the last 48 h of life; the COVID +ve cohort were more present virtually. Overall, 35 family members (28.9%) had severe grief symptoms, and the prevalence was similar among the cohorts ( p = 0.91). Grief severity was not correlated with demographic factors, physical presence in the final 48 h of life, intubation, or relationship with the deceased.

Conclusion:

Severe grief is common among family members bereaved during the COVID-19 pandemic, regardless of the cause or circumstances of death, and even if their loss took place before the onset of the pandemic. This suggests that aspects of the pandemic itself contribute to severe grief, and factors that normally mitigate grief may not be as effective.
Hyperoxia evokes pericyte-mediated capillary constriction
Authors: Hirunpattarasilp Chanawee , Barkaway Anna , Davis Harvey , Pfeiffer Thomas , Sethi Huma , Attwell David
Published: July 2022

Oxygen supplementation is regularly prescribed to patients to treat or prevent hypoxia. However, excess oxygenation can lead to reduced cerebral blood flow (CBF) in healthy subjects and worsen the neurological outcome of critically ill patients. Most studies on the vascular effects of hyperoxia focus on arteries but there is no research on the effects on cerebral capillary pericytes, which are major regulators of CBF. Here, we used bright-field imaging of cerebral capillaries and modeling of CBF to show that hyperoxia (95% superfused O2) led to an increase in intracellular calcium level in pericytes and a significant capillary constriction, sufficient to cause an estimated 25% decrease in CBF. Although hyperoxia is reported to cause vascular smooth muscle cell contraction via generation of reactive oxygen species (ROS), endothelin-1 and 20-HETE, we found that increased cytosolic and mitochondrial ROS levels and endothelin release were not involved in the pericyte-mediated capillary constriction. However, a 20-HETE synthesis blocker greatly reduced the hyperoxia-evoked capillary constriction. Our findings establish pericytes as regulators of CBF in hyperoxia and 20-HETE synthesis as an oxygen sensor in CBF regulation. The results also provide a mechanism by which clinically administered oxygen can lead to a worse neurological outcome.
Arterial input functions in dynamic susceptibility contrast MRI (DSC-MRI) in longitudinal evaluation of brain metastases
Authors: Starck Lea , Skeie Bente Sandvei , Bartsch Hauke , Grüner Renate
Published: July 2022

Background

Dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) could be helpful to separate true disease progression from pseudo-progression in brain metastases when assessing the need for retreatment. However, the selection of arterial input functions (AIFs) is not standardized for analysis, limiting its use for this application.

Purpose

To compare population-based AIFs, AIFs specific to each patient, and AIFs specific to every visit in the longitudinal follow-up of brain metastases.

Material and Methods

Longitudinal data were collected from eight patients before treatment (6 of 8 patients) and after treatment (6–17 visits). Imaging was performed using a 1.5-T MRI system. Lesions were segmented by subtracting precontrast images from postcontrast images. Cerebral blood volume (rCBV) and cerebral blood flow (rCBF) were computed, and Pearson's product moment correlation coefficients were calculated to evaluate similarity of DSC parameters dependent on various AIF choices across time. AIF shape characteristics were compared. Parameter differences between white matter (WM) and gray matter (GM) were obtained to determine which AIF choice maximizes tissue differentiation.

Results

Although DSC parameters follow similar patterns in time, the various AIF selections cause large parameter variations with relative standard deviations of up to ±60%. AIFs sampled in one patient across sessions more similar in shape than AIFs sampled across patients. Estimates of rCBV based on scan-specific AIFs differentiated better between perfusion in WM and GM than patient-specific or population-based AIFs ( P ≤ 0.02).

Conclusion

Results indicate that scan-specific AIFs are the best choice for DSC-MRI parameter estimations in the longitudinal follow-up of brain metastases.
Collections, care, and the collective: Experiments in collaborative fieldwork in area studies librarianship
Authors: Ambrosone Ellen A , Ring Laura A , Thacker Mara L
Published: July 2022

While scholarship in library science continues to expand understanding of collaboration and its potential to transform the collective collection, librarian acquisitions trips have been largely absent from the conversation. In early 2020, three US-based South Asian studies librarians traveled together to India, jettisoning solo travel in favor of a model of collaborative fieldwork. Using this trip as a case study, the authors draw on interdisciplinary literature to explore how intersecting identities and the embodied nature of fieldwork shape outcomes for the collective collection. They reflect on how foregrounding care in the field can converge with efforts to build more ethical collections. Finally, the authors consider the possibilities of a shift toward collaboration beyond mere coordination, and offer suggestions for how a relational perspective might be advocated for in their work. At the intersection of theory and practice, this article helps readers understand the holistic work behind area studies librarianship, and offers a vision of improved practice in the field.
IPCC and the City: The Need to Transition from Ideology to Climate Justice
Authors: Lejano Raul P. , Kan Wing Shan
Published: July 2022

The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) has been released. In it, several sections address climate change, mitigation, and adaptation in cities, with discussions of the crucial role of planning and governance in the same. This article offers a reflection on the urban elements of AR6, pointing to the prevalence of ideological elements in it, typologizing form over critical assessments of real conditions in developing cities. As much as AR6 emphasizes the carbon footprint of society, it ignores the social footprint of carbon and the potentially massive adjustments mitigation and adaptation will require of developing nations and their urban populations.
Pedagogy, Podcasts, and Politics: What Role Does Podcasting Have in Planning Education?
Authors: Moore Thomas
Published: July 2022

This paper systematically reviews the use of podcasts in planning education. Podcasting is part of a broader expansion and diversification of digital technology in education, responding to its use in teaching approaches and research dissemination. The ability to gather and share information across time and space, alongside emphases on dialogue, participation, and voice, also means that podcasts may hold emancipatory potential. This systematic review highlights how podcasts may support active learning among students and create dialogues between students and communities under-represented in mainstream debate, and the extent to which they may enhance strategies of blended and active learning in planning curricula.

Published: July 2022

Past research on ethnocultural minority students indicates that persistent inequities require greater attention to the multiple learning supports needed to enhance school success. The present study was designed to extend research in this area by exploring school climate and emotional engagement among minority ethnocultural Chinese students in Malaysian secondary schools. We employed quantitative surveys with 724 students ( Mage = 16.1 years; 47.9% female), followed by qualitative interviews with a subset of 25 students ( Mage = 16.1 years; 52% female). Path analysis indicated that feelings of safety, socio-emotional support from teachers and peers, and student voice were predictors of emotional engagement for Chinese students, which further predicted cognitive engagement, academic performance, and school behavior. Thematic analysis further revealed that language and communication barriers and bullying negatively impacted students’ sense of safety and engagement. Caring, respectful relationships with teachers led to students having opportunities to direct their own learning and make decisions on schoolwide activities, promoting students’ feelings of engagement. Support from peers increased students’ emotional engagement by reducing school-related stressors. The findings suggest that a mutually respectful, caring school climate and opportunities for student voice can enhance critical school experiences for ethnocultural minority high school students.
Hospital Variation in Mortality and Ventilator Management among Mechanically Ventilated Patients with ARDS
Authors: LeSieur Mallory N. , Bosch Nicholas A. , Walkey Allan J.
Published: July 2022

Rationale

Acute Respiratory Distress Syndrome (ARDS) is associated with significant mortality. Despite the mortality benefits of lung protective ventilation, adherence rates to evidence-based ventilator practice have remained low and ARDS mortality has remained high.

Objective

Determine variation in ARDS mortality and adherence to low tidal volume ventilation (LTV) across US hospitals.

Materials and Methods

We identified mechanically ventilated patients with ARDS using data from Philips eICU (2014-2015). We then used multi-variable hierarchical logistic regression models with hospital site as the random effect and patient and hospital level factors as fixed effects to assess the hospital risk adjusted mortality rate and median odds ratio for the association between mortality and hospital site. We then assessed associations between adherence to LTV (defined as 4-8 mL/kg PBW) and hospital risk adjusted mortality rates using Spearman correlation.

Results

Among 4441 patients admitted at 110 hospitals with ARDS, the hospital risk-adjusted mortality rate ranged from 19% to 39%, and the MOR for hospital of admission was 1.33 (95% CI 1.25-1.41). Among 3070 patients at 72 hospitals with available ventilator data, 73% of patients had a median set Vt between 4 to 8 mL/kg PBW; hospital adherence rates to LTV ranged from 13% to 95%. There was no association between hospital adherence to LTV and risk-adjusted mortality rate (spearman correlation coefficient −0.01, p = .93). Similarly, among 956 patients who started with a Vt > 8 mL/kg PBW, there was no association between the percent of patients at each hospital whose Vt was decreased to ≤ 8 mL/kg PBW and risk adjusted mortality rate (spearman correlation coefficient .05, p = .73).

Conclusion

Risk adjusted mortality and use of LTV for patients with ARDS varied widely across hospitals. However, hospital adherence to LTV was not associated with ARDS mortality rates. Further evaluation of hospital practices associated with lower ARDS mortality are warranted.
Incorporation of an Efficient Pharmacist Workflow During the Transition From In-Person to Telemedicine Geriatric Clinics in Response to the COVID-19 Pandemic

Published: July 2022

The COVID-19 pandemic created care continuity challenges for older adults in the ambulatory care setting. Similarly, maintaining the multidisciplinary team concept of geriatric care among healthcare practitioners working from home presented several logistical difficulties. It became apparent there was a need to address these problems to avoid care gaps in this vulnerable population. Realizing that in-person clinics could put vulnerable older adults at increased risk of contracting COVID-19, a workflow was proactively developed to convert a traditional in-person multidisciplinary geriatric clinic to a telemedicine-based model. A video patient encounter option within our electronic health record along with a secure on-line meeting platform was used to maintain a team-based approach to care. This resulted not only in a high level of efficiency in care delivery, but also ensured the safety of older adult patients served by the clinic. This model provides a template for the continued use of telemedicine as a strategy for the care of vulnerable older adults who experience challenges with attending in-person clinics.
Perceived Organizational Support and Volunteer Outcomes: Evidence From a German Environmental Nonprofit Organization
Authors: Traeger Charlotte , Alfes Kerstin , Fürstenberg Nils
Published: July 2022

While research on organizational aspects designed to enhance volunteer attitudes has grown over time, we still lack knowledge on the mechanisms that explain these relationships and are specific to the volunteering context. In the present study, we draw on social identity theory to explore how two organizational characteristics relating to a nonprofit organization’s (NPO) nature (volunteers’ organizational vision acceptance) and nurture (volunteers’ perception of organizational support) interact to promote volunteers’ engagement and retention. Findings from a survey of 1,355 volunteers in a German environmental NPO show that the relationship between perceived organizational support and both volunteer outcomes is mediated by organizational identification and moderated by volunteers’ acceptance of organizational vision. We contribute to research on the professionalization of volunteer management by highlighting the importance of volunteers’ acceptance of their NPO’s vision for their engagement and intention to leave.
Radical Change and Institutional Resilience: The Case of Labour Market Reforms in Southern Europe
Authors: Álvarez Ignacio , Cruces Jesús , Trillo Francisco
Published: July 2022

Over the last decade southern European labour markets have been transformed in a common neoliberal direction, as a consequence of the reforms enacted after the 2008 financial crisis. In our research we investigate to what extent these labour market reforms, aimed at promoting a radical decentralisation of collective bargaining, have actually led to such change. For that purpose, we developed a comparative study of Spain and Portugal, using the notions of path dependency and socio-political coalitions developed by historical institutionalism. Our study leads to the conclusion that institutional trajectories resulting from these labour market reforms merge profound changes with significant resilience. The neoliberal transformations of southern European labour markets have not led to the emergence of new bargaining models, nor to an institutional convergence towards the decentralised collective bargaining systems of liberal market economies. Rather, these reforms have triggered a disorganised fragmentation of collective bargaining systems, resulting in a lack of institutional coherence.
Developing competencies in higher education: Insights from a Brazilian higher education institution
Authors: Almeida de Camargo Pereira Marcelo , Felicetti Vera Lucia
Published: July 2022

This paper examines the connections and influences of the job market in a Brazilian higher education setting. Adopting a qualitative approach and a technical case study procedure, open and semi-structured interviews were conducted and analyzed through the discursive textual analysis technique. From the words of the Dean and the Chair of a business management program in a Brazilian higher education institution and the employers of some of its graduates, the authors note that the education delivered is directly influenced and fueled by actual problems and settings in the labor market. Nonetheless, the same market that welcomes these new professionals does not realize its influence and still requires certain behavioral and interpersonal skills from them.
Quantification of longitudinal fastener stiffness and the effect on fastening system loading demand
Authors: Khachaturian Christian , Dersch Marcus S , Edwards J Riley , Trizotto Matheus
Published: July 2022

Over the past 20 years, there have been at least 10 derailments due to spike fastener fatigue failures in North America. These fatigue failures have been considered a moderate to severe challenge that require manual walking inspections that are both time and labor intensive. These fatigue failures have been found to result from spike overloading due to lateral and longitudinal loads. To date, there has been limited quantification of the vertical, lateral, and longitudinal fastener forces in track. This paper quantifies the effect of fastener type on fastener load to account for various track types and locations. Laboratory experimentation was performed to quantify the stiffness of multiple fastening systems and this data was input into a previously validated analytical model to quantify the effect of stiffness on fastener loading. Additional laboratory experimentation was performed to quantify the relationships between both fastening system type and vertical loading and spike strain. While the laboratory data indicate a significant variance in stiffness between fastening systems, the model results indicate that the load transferred to the fastening system is less sensitive. However, spike strain data indicate the load path was affected by fastener type and vertical load. The characterization of longitudinal stiffness of multiple fastening systems and the relationship to spike load as presented can be used to advance track mechanistic-empirical design and improve rail neutral temperature prediction and track buckling models.
Establishing a Guide for Developing Organizational Support in Healthcare Following a Critical or Sentinel Event
Authors: Austin Diana Maree , Pauley Gerard , Ferkins Lesley
Published: July 2022

Health professionals require support and recognition to help manage the well-known impact of critical or sentinel events relating to patient care. The potential distress can be magnified or mitigated by the response of the organization and colleagues. However, strategies that are accessible, relevant, and effective in the aftermath of a poor outcome are not well established. Using an action research methodology, a support tool was collaboratively designed, developed, and evaluated in a maternity service of one organization and adapted to the mental health and addiction service in another. Four principles that are intrinsic to the establishment of support tools became apparent across the two settings. Through applying these criteria to the customization of the support tool, it became relevant within the new service setting, and an implementation guide for other organizations was created. Although undertaken pre-pandemic, insights derived from this study may benefit post-pandemic situations where the need for health professional support is even greater.
A Systematic Review of the Cost-Effectiveness of Cleft Care in Low- and Middle-Income Countries: What is Needed?
Authors: Chung Karen Y. , Ho George , Erman Aysegul , Bielecki Joanna M. , Forrest Christopher R. , Sander Beate
Published: July 2022

Objective

The objective of this paper is to conduct a systematic review that summarizes the cost-effectiveness of cleft lip and/or palate (CL/P) care in low- and middle-income countries (LMICs) based on existing literature.

Design

We searched eleven electronic databases for articles from January 1, 2000 to December 29, 2020. This study is registered in PROSPERO (CRD42020148402). Two reviewers independently conducted primary and secondary screening, and data extraction.

Setting

All CL/P cost-effectiveness analyses in LMIC settings.

Patients, Participants

In total, 2883 citations were screened. Eleven articles encompassing 1,001,675 patients from 86 LMICs were included.

Main Outcome Measures

We used cost-effectiveness thresholds of 1% to 51% of a country's gross domestic product per capita (GDP/capita), a conservative threshold recommended for LMICs. Quality appraisal was conducted using the Joanna Briggs Institute (JBI) checklist.

Results

Primary CL/P repair was cost-effective at the threshold of 51% of a country's GDP/capita across all studies. However, only 1 study met at least 70% of the JBI criteria. There is a need for context-specific cost and health outcome data for primary CL/P repair, complications, and existing multidisciplinary management in LMICs.

Conclusions

Existing economic evaluations suggest primary CL/P repair is cost-effective, however context-specific local data will make future cost-effectiveness analyses more relevant to local decision-makers and lead to better-informed resource allocation decisions in LMICs.
Exploring Bidirectional Language–Behavior Influences for Spanish–English Dual Language Learning Children in Head Start
Authors: Juhasz Audrey C. , Boyce Lisa K.
Published: July 2022

The purpose of this exploratory study was to examine the longitudinal, bidirectional relations between receptive and expressive Spanish and English language and internalizing and externalizing behavior problems in a sample of 97 preschool children from Spanish-speaking, homes who were enrolled in a U.S. Head Start program. Eight cross-lagged path models were conducted: four for each language. Models tested the autoregressive and cross-lagged paths between two dimensions of language (expressive and receptive) and behavior problems (internalizing and externalizing) over the preschool year. Findings highlight the critical importance of the home language for children who are dual language learners and suggest programs ensure adequate home language support is available in the classroom. Future directions are discussed.
Supramalleolar Osteotomy for Ankle Varus Deformity Alters Subtalar Joint Alignment
Authors: Burssens Arne , Susdorf Roman , Krähenbühl Nicola , Peterhans Ursina , Ruiz Roxa , Barg Alexej , Hintermann Beat
Published: July 2022

Background:

Although correction of ankle and hindfoot deformity after supramalleolar osteotomy has been investigated extensively, the specific effect on the subtalar joint alignment remains elusive. This can be attributed to the limitations of 2-dimensional measurements, which impede an exact quantification of the 3-dimensional subtalar joint alignment. Therefore, we determined both the ankle, hindfoot, and subtalar joint alignment before and after supramalleolar osteotomy using autogenerated 3-dimensional measurements based on weightbearing CT imaging.

Methods:

Twenty-nine patients with a mean age of 50.4±10.6 years were retrospectively analyzed in a pre-post study design using weightbearing CT. Inclusion criteria were correction of ankle varus deformity by an opening wedge (n = 22) or dome osteotomy (n = 7). Exclusion criteria consisted of an additional inframalleolar arthrodesis or osteotomy. Corresponding 3-dimensional bone models were reconstructed to compute following autogenerated measurements of the ankle- and hindfoot alignment: tibial anterior surface (TAS), tibiotalar surface (TTS), talar tilt (TT) angle, hindfoot angle (HA). In addition, the talocalcaneal angle (TCA) in the axial (TCAax), sagittal (TCAsag), and coronal (TCAcor) plane were measured to assess the subtalar joint alignment.

Results:

The preoperative radiographic parameters of the ankle joint alignment (TAS=88±4 degrees, TTS=82±7 degrees, TT=5.8±4.9 degrees) improved significantly relative to their postoperative equivalents (TAS = 93±5 degrees, TTS = 88±7 degrees, TT=4.2±4.5 degrees; P < .05). The following radiographic parameters of the hindfoot and subtalar joint alignment improved significantly from preoperatively (8.7±8.9 degrees, TCAax = 41±10 degrees, TCAsag = 48±10 degrees) to postoperatively (HA=4.5±8.6 degrees, TCAax = 38±9 degrees, TCAsag = 44±11 degrees; P < .05). No significant differences could be detected in the coronal plane alignment of the subtalar joint (TCAcor) pre- compared to postoperatively ( P > .05).

Conclusion:

This study quantified the 3-dimensional ankle, hindfoot, and subtalar joint alignment after a solitary supramalleolar osteotomy. We found alterations in the subtalar joint alignment, which occurred by 2 to 3 degrees in each anatomic plane. However, before recommendations can be given related to inframalleolar procedures in conjunction to supramalleolar osteotomies, further studies on the variation of subtalar joint alignment change are needed.

Published: July 2022

Caregivers of persons with dementia (PWDs) were socially isolated with little support during the COVID-19 pandemic “Stay-At-Home” order in the United States. To enhance social and emotional connection for diverse caregivers, a culturally/linguistically appropriate telephone intervention provided compassionate listening, mindful breathing, and COVID-19 safety education. The study purpose was to understand caregiving challenges and to evaluate the intervention for caregivers during the early pandemic using a qualitative approach. Twenty-three caregivers participated in the intervention provided by bilingual research assistants for 3 months. Call logs were used to describe the caregivers’ dialogue. Thematic analysis identified (a) the challenges, including fear of coronavirus disease, providing around-the-clock care, and forced isolation and negative emotions; and (b) caregivers’ experience with the intervention, including connecting with the outside, relief from emotional stress, reliable COVID-19 information, and reinformed caregiving skills. Results suggest that the telephone support was of benefit to diverse caregivers of PWDs during the pandemic by promoting social connection and reducing emotional distress.
Whole-Grade Acceleration: From Student to Policy
Authors: Lupkowski-Shoplik Ann , Assouline Susan G. , Lange Randolph
Published: July 2022

Whole-grade acceleration moves a student up one or more grades in response to that student’s academic needs. Although grade-skipping is supported by decades of research, this type of acceleration is not often used. Acceleration policies make whole-grade acceleration available to more students who would benefit, encourage more educators to use the intervention, and result in more equitable access of acceleration to qualified students. Whole-grade acceleration policies detail the entire process of obtaining accelerated placement and services—from the referral of the student through the transition to acceleration. A child-study team (not an individual) makes the decision, addresses academic gaps, and monitors the student’s transition to acceleration. Acceleration policies help ensure this intervention is implemented consistently. Utilizing excellent acceleration policies can result in students achieving the developmental goal of competence and engagement in learning.
A g-Normal fuzzy relational hybrid model based control design for hybrid systems with continuous-valued inputs
Authors: Zhoulai Bakhoda Omid , Menhaj Mohammad Bagher , Aghili-Ashtiani Arya
Published: July 2022

In this paper, the indirect adaptive control of a special class of hybrid systems is proposed. The proposed control scheme is based on g-normal fuzzy relational hybrid models (g-Normal FRHMs) in which the model of both plant and controller are proposed to be modeled by FRHM structure. There is an assumption on control action to be of continuous-valued type. In order to design a control scheme for both regulation and reference tracking, an additional simplifying assumption is considered. Indeed, when the tuning mechanism is extracted, it is assumed that the defuzzifier of the controller’s model and the fuzzifier of the plant’s model are approximately inverse of each other and can be simplified. The proposed control approach is then applied to a DC-DC buck converter as our case study. The simulation results show that the proposed adaptive control based on g-Normal FRHM can regulate and also track the reference input in the presence of both load and supply voltage disturbance.
Maintaining ideological security and legitimacy in digital China: Governance of cyber historical nihilism
Authors: Xu Jian , Gong Qian , Yin Wen
Published: July 2022

This article studies the governance of ‘cyber historical nihilism’ in China. By performing document analysis of the regulatory policies and actions against cyber historical nihilism, we found that cyber historical nihilism is mainly governed as harmful ‘online content’ and a threatening ‘ideological trend’, and its governance has incorporated agencies and measures of China’s ‘internet governance’ and ‘ideological and political education’. We argue that cyber historical nihilism has been securitised by the Chinese Communist Party as an urgent threat to the nation’s ideological and political securities. The governance of cyber historical nihilism aims to maintain the Chinese Communist Party’s authority in history writing and its legitimacy and longevity as the ruling party. The Chinese Communist Party’s emphasis and intensity in governing cyber historical nihilism has not only demonstrated the ideological turn to Maoism in internet governance, propaganda and politics under Xi Jinping’s leadership, but also the Chinese Communist Party’s ability and resilience to adapt to new challenges in the ideological field in the digital age.

Utilizing the balloon anchoring technique to improve device deliverability during stent revascularization for atherosclerotic renal artery stenosis
Authors: Huang Xiang , Li Xiao-Lan , Zhou Heng
Published: July 2022

Introduction

The stent revascularization for severely calcified renal artery lesions can be challenging, due to a deficiency in back-up force provided by the guide catheter. The aim of this report is to describe the use of the balloon anchoring technique to increase device maneuverability and deliverability after the failure of conventional renal artery revascularization.

Technical note

This technique was adopted in a patient with subtotal occlusive and severely calcified lesion in the proximal portion of the right main renal artery. Two guidewires were separately introduced into the proximal side branch (SB) and main branch (MB) of the renal artery. Anchor balloon inflated at low pressure in SB, anchoring the MB-wire and the guide catheter, thus giving us the ability to cross the tight calcified proximal cap of the MB lesion with a non-compliant balloon. After performing pre-dilatations and retrieving the anchor balloon, we implanted a balloon-expandable stent and achieved optimal final angiographic results.

Conclusions

The balloon anchoring technique can improve device maneuverability and deliverability during various catheterization procedures. Our report firstly demonstrates how to perform the balloon anchoring technique in renal angioplasty treatment and then explains its effectiveness in revascularization of the renal artery with challenging anatomies.
How can social support make coaching less stressful? A longitudinal inquiry with sports coaches
Authors: Norris Luke A. , Didymus Faye F. , Kaiseler Mariana
Published: July 2022

Research on social support with sports coaches is limited, yet the benefits of social support on performance and well-being within other occupations have been widely reported. This study explored sports coaches’ social support resources over a six-week period to understand how social support resources may alleviate stressors. Longitudinal data were collected from women ( n = 6) and male ( n = 4) sports coaches ( Mage = 35.2, SD = 13.0 years, Mexperience = 13.5, SD = 9.7 years) using three semi-structured interviews over a six-week training and competition period. Interview data were analysed using abductive thematic analysis. Coaches used all four types of social support resources over the six-week period. Informational support for advice, ideas, and feedback on training sessions, new job roles, and player development was used most regularly across the different time points. Coaches also reported that they perceived social support resources may alleviate stressors through stress-buffering and main-effects Social support resources (e.g. esteem) might be more important for buffering the effects of stressors and others (e.g. emotional) may be more important for the main-effects. Given the pertinence of social support resources for performance and psychological well-being, applied interventions should aim to educate coaches on ways to develop a social support network that provides all types of social support resources to help cope more effectively with stressors. Moreover, interventions should aim to alter coaches’ perceptions of potential stressors as less of a threat and more of a challenge to alleviate the prospective negative influences of stressors.
Rail policies in Turkey after 2002: Is there a modal shift?
Authors: Solak Ali Osman
Published: July 2022

Since 2002, the Turkish government has increased its interest in rail transport after neglecting it for more than half a century. The government invested significant sums in the high-speed network and allocated substantial funds for the modernization of conventional rail infrastructure, the expansion of the network, and the construction of logistics centers. In addition, in 2013, the government restructured the rail market and opened it to competition. This paper examines recent rail policy in terms of modal shift to determine whether there is a radical shift in national transportation policy, which has been dominated by road programs. Despite significant steps to help rail achieve a breakthrough, our analysis does not show a strong shift in investment priorities that would lead to modal shift.
Tourism Development and Income Inequality in Sub-Saharan Africa: Does Governance Matter?
Authors: Odhiambo Nicholas M.
Published: July 2022

This study examines the relationship between tourism development, governance, and income inequality in 31 sub-Saharan African (SSA) countries. In the main, the study aims at examining whether tourism inflows ameliorate or exacerbate income inequality in the studied countries. The study also aims to examine whether institutional governance modulates the impact of tourism development on income inequality. For robustness, four proxies of governance indicators have been used, namely, the rule of law, voice and accountability, political stability, and government effectiveness, thereby leading to four separate specifications with four interaction variables. The Generalized Method of Moments (GMM), which accounts for endogeneity, has been used to examine this linkage. Contrary to some of the previous studies, the results of our study show that an increase in tourist arrivals leads to a decrease in income inequality in the studied SSA countries. The results also show that the favorable negative impact of tourism on income inequality could switch to an unfavorable positive impact if the following levels of governance are exceeded: 1.6842, 3.1429, and 0.7436 for voice and accountability, political stability, and government effectiveness, respectively. Policy implications are discussed.
Addressing Vaccine Hesitancy Among Students and Families: Interventions for School Nurses
Authors: Wilson Olivia F. , Mote Sandra L. , Morse Brenna L.
Published: July 2022

Vaccine hesitance is a public health issue that school nurses often address in practice. It has become even more prevalent during the coronavirus disease 2019 (COVID-19) pandemic. Vaccine compliance among schoolchildren is essential to the health of an entire community, given that many pediatric illnesses are vaccine-preventable. School nurses are involved in the promotion of vaccines in a school district, as they provide health education to students and families and are responsible for vaccine surveillance. Promoting vaccine compliance as a matter of public health can be challenging for school nurses, especially if a community holds strong beliefs regarding the necessity of pediatric vaccines. This article reviews the history of vaccine mandates, addresses challenges associated with vaccine compliance, and provides interventions school nurses can use when providing care to students and families regarding vaccine hesitancy. In following the nursing process, a school nurse is able to identify students missing vaccine(s) and evaluate for hesitancy, before implementing interventions that provide education to students and families. Several cost-efficient and accessible interventions can facilitate effective education and promote vaccine compliance. School nurses can forge trusting relationships and engage in compassionate dialogue to support vaccine compliance in the school.

Read the answers to these frequently asked questions to learn how and why school nurses should earn the NCSN credential.
Social data governance: Towards a definition and model
Authors: Liu Jun
Published: July 2022

With the surge in the number of data and datafied governance initiatives, arrangements, and practices across the globe, understanding various types of such initiatives, arrangements, and their structural causes has become a daunting task for scholars, policy makers, and the public. This complexity additionally generates substantial difficulties in considering different data(fied) governances commensurable with each other. To advance the discussion, this study argues that existing scholarship is inclined to embrace an organization-centric perspective that primarily concerns factors and dynamics regarding data and datafication at the organizational level at the expense of macro-level social, political, and cultural factors of both data and governance. To explicate the macro, societal dimension of data governance, this study then suggests the term “social data governance” to bring forth the consideration that data governance not only reflects the society from which it emerges but also (re)produces the policies and practices of the society in question. Drawing on theories of political science and public management, a model of social data governance is proposed to elucidate the ideological and conceptual groundings of various modes of governance from a comparative perspective. This preliminary model, consisting of a two-dimensional continuum, state intervention and societal autonomy for the one, and national cultures for the other, accounts for variations in social data governance across societies as a complementary way of conceptualizing and categorizing data governance beyond the European standpoint. Finally, we conduct an extreme case study of governing digital contact-tracing techniques during the pandemic to exemplify the explanatory power of the proposed model of social data governance.
Psychometric Properties of the Sport Multidimensional Perfectionism Scale-2 in Czech Adolescent Athletes: An Exploratory Approach
Authors: Květon Petr , Jelínek Martin , Burešová Iva
Published: July 2022

This study presents a thorough examination of the psychometric properties of the Czech version of the Sport Multidimensional Perfectionism Scale-2 in adolescent athletes. Factorial structure, external validity, and internal consistency were evaluated using a cross-sectional design. In addition, three-month temporal stability was also assessed. The cross-sectional study sample consisted of 243 respondents (50.2% females; mean age 16.40 years). Factorial structure of the Sport-MPS-2 was examined using exploratory factor analysis, evidence for external validity was based on bivariate and canonical correlations with Big Five Inventory-2 (short) and Sport Anxiety Scale-2. The longitudinal part of the study was performed on a subsample of 96 participants. Factorial structure in our sample fully corresponded to the structure suggested by the authors of the instrument. Internal consistencies of subscales were satisfactory. Regarding external validity, Doubts about Actions and Concern over Mistakes were positively related to sport anxiety, and positive relationship was found also between Concern over Mistakes and Negative Emotionality. No substantial relationships were found in case of subscales constituting perfectionistic strivings. Temporal stability of Sport-MPS-2 over three months was satisfactory. The Czech version of Sport-MPS-2 can be considered a reliable instrument for assessing perfectionism in sport in the adolescent population.

Authors: Salam Sidra , Senin Aslan Amat
Published: July 2022

Innovation is a significant method of ensuring excellence and competitiveness for contemporary organizations. Therefore, employees are highly motivated to involve in innovative behavior which comprises developing novel and beneficial ideas, sharing ideas of your own or other people to colleagues, and putting those ideas into practice. This bibliometric analysis aims to have a deeper understanding and an advanced knowledge about “innovative behavior” both theoretical and recent research developments using the Scopus database. The study was carried out to see the patterns in publication between 1961 and 2019; authors, journals, countries, academic discipline, research institutes/universities, and various keywords relevant to “innovative behavior” were used as search words. After thorough consideration and the use of multiple checkpoints to remove irrelevant studies, 931 research papers were reviewed. In the analysis of authors’ keywords “innovation” was the most frequently occurred among other keywords. The data has shown a stronger link between “innovative behavior” and “innovation” with 34 occurrences. We noticed that “innovative behavior” has the highest occurrence with 264 times with 37 links and 235 total link strength in which the innovative behavior links with some variables such as leadership, organizational commitment, knowledge sharing, entrepreneurship, psychological empowerment, organizational culture, work engagement, innovative climate, and employee behavior. These are the major concepts that occurred within “innovative behavior” research. Along with future guidelines and study limitations, certain variables with infrequent occurrences are also discussed.
The place of the public notary: How the engine of the capitalist state operates through material and legal arrangements
Authors: Latorre Sergio
Published: July 2022

This article explores the institution of the public notary in Colombia as an important place for legality where we can appreciate different mechanisms through which law is productive of space and space shapes understandings of the legitimacy of law. I study the notary as a material and social space of interactions between persons (parties, lawyers and public officials), non-human actors (seals, signatures, fingerprints) and practices (solemn oaths, making of deeds). I highlight three aspects. First, at the notary the relationship between the private and public orders is enacted. Private actions (birth, marriage or sell of property) once notarized through the stamping of the seal are now public acts. Second, contrary to think of the notary as space empty of law since it does not solve any legal controversies, I argue that particular legal knowledge practices at the notary consolidate processes of individuation and reification essential for the making of both, persons (criticizes) and things (property); these practices are also key in the making of the state’s authority. Finally, I review the relationship between the notary and the instrument (the sealed document) to reveal the importance of certain ideas such as “public faith”. These ideas allow the notary to detach him/herself from the agency of the instrument; however, inherent indeterminacies remain in these configurations that reveal the temporal and variable character of the reality the notary attest to. This is important because when we partake in the formalization regimes happening at these places, we implicitly accept and maintain some of these cognitive constructions that constitute important pillars for both, the market and the state.
