I Will Be Green for Us: When Consumers Compensate for Their Partners’ Unsustainable Behavior
Authors: Cakanlar Aylin , Nikolova Hristina , Nenkov Gergana Y.
Published: June 2022

In the context of romantic relationships, partners regularly observe each other's unsustainable behavior. But how do these unsustainable behaviors influence each member of the couple? This research shows that how consumers respond to their partners’ unsustainable behaviors depends on the amount of relationship power they possess: high-relationship-power individuals compensate for their partners’ unsustainable behavior by acting in a more sustainable manner relative to their baseline tendencies, but low-relationship-power individuals do not increase their own sustainable behavior. This effect occurs because high-relationship-power partners feel more responsible for the reconstruction of the couple identity after it has been damaged by their partner's unsustainable choice; as a result, they have a stronger desire to signal a positive couple identity (i.e., a positive couple sustainable identity). Consistent with this theory, this effect is attenuated for high-relationship-power individuals who have weak green identities. Seven studies provide evidence for these findings by measuring and manipulating relationship power and assessing hypothetical and actual sustainable behaviors. This research contributes to the sustainable behavior literature and highlights effective ways to promote sustainable behavior in households.

Authors: Goodman Melody S. , Bather Jemar R. , Chu Xiangying , Pagano Marcello , Plepys Christine M. , Sebro Ronnie A.
Published: June 2022

Objective:

This study is a follow-up to a study in 2020 that reviewed changes in the racial and ethnic composition of public health students, graduates, and faculty among Association of Schools and Programs of Public Health (ASPPH)–member institutions. In the current study, we evaluated how the racial and ethnic composition among biostatistics and epidemiology students, graduates, and faculty changed from 2010 to 2020.

Methods:

We analyzed data on race and ethnicity of enrolled graduate students, graduates (master’s and doctoral), and faculty at ASPPH-member institutions by using institutionally reported data from the ASPPH Data Center. We tabulated frequencies, percentages, and percentage-point changes by race and ethnicity. We measured differences between groups by using a test for difference in 2 proportions.

Results:

The number of enrolled students, graduates, and faculty in all departments increased during the study period, while the number of tenure-track faculty in biostatistics decreased. The percentage of enrolled Hispanic/Latino biostatistics graduate students increased from 5.6% in 2010 to 10.2% in 2020 ( P = .007), and the percentage of epidemiology graduates increased from 8.8% to 13.8% ( P = .008). We found no differences among other underrepresented racial and ethnic groups. Most biostatistics and epidemiology professors at all ranks were non-Hispanic White, despite substantial decreases. The percentage of underrepresented racial and ethnic minority biostatistics and epidemiology professors was constant across all ranks.

Conclusion:

Although more Hispanic/Latino students are enrolled in and graduating from biostatistics and epidemiology departments at ASPPH-member institutions, we found no change among faculty. More work is needed to recruit and retain other (American Indian/Alaska Native, Black or African American, Native Hawaiian/Other Pacific Islander) underrepresented students and faculty.
Supporting Families to Motivate Their Middle School Student During Homework Time
Authors: Payne S. Blair , Swanson Elizabeth
Published: June 2022

Nearly every secondary-age student must complete homework for their classes, and for many students with disabilities, completing homework at home is a struggle. Students with disabilities often require substantial support to execute homework assignments, and this responsibility frequently falls to their families. This dynamic can create a stressful environment for working at home. Although supports may be in place at school to ensure a student’s success, at home, families often wonder how to reduce stress and improve their child’s success during homework time. This article provides middle and high school special education teachers and case managers with a step-by-step plan for supporting families and their students as they plan for and implement a structured homework routine with built-in supports.

Published: June 2022

Factories must proof different colors on fabric in order to verify the feasibility of the color scheme. This proofing process is time-consuming and laborious. To recolor printed fabric images, a novel image recoloring method was proposed in this paper. This method can provide convenience for printed fabric designers and can be used to simulate printed fabric proofing. The relative total variation model was implemented to remove the fabric image texture and noise. Next, in the CIE1976 L* a* b* color space, the mean-shift clustering algorithm was utilized to segment the reference image and the target image to obtain the separated color regions. Then, the color regions of the reference image and the target image were matched based on the salient map and the values of the L* a* b* channels. Finally, local color transfer was performed between the matched color regions based on the matching results. Experiments were conducted on 100 printed fabrics with different color schemes. Results indicated that the proposed method can transfer the color appearance of the reference printed fabric image to the target printed fabric image and realize printed fabric image recoloring.
Older Adults Place Greater Importance Than Younger Adults on a Purposeful Retirement
Authors: Hill Patrick L. , Best Rachel D. , Pfund Gabrielle N. , Cardador M. Teresa , Strecher Victor J.
Published: June 2022

Objective: Regarding retirement, some but not all people decline in sense of purpose, and retirees may view maintaining a sense of purpose as nonessential. These findings suggest individual differences both in the importance placed on being purposeful during retirement in general and the discrepancy for purpose importance prior to and during retirement. Method: This study surveyed U.S. adults ( n = 2009, Mage = 48.51) asking them about how they viewed having a purpose in two life stages: before and during retirement, as well as personality and demographic questions. Results: Findings suggest that, overall, people believe it is important to have a purpose and direction during retirement. This tendency was greater among older adults, and those higher on conscientiousness or lower on neuroticism. However, working status did not play a role in the perceived importance of purpose during the retirement period. Moreover, age differentiated who perceives during-retirement purpose as more important than prior-to-retirement purpose. Conclusion: The current findings add to our understanding of when individuals expect to be purposeful and counter the claims that older adults may place less importance on being purposeful. Instead, these findings point to the need for continuing work on how to help older adults maintain or find a purpose in life following retirement.
Signed languages – Unique and ordinary: A commentary on Kidd and Garcia (2022)
Authors: Lillo-Martin Diane , Hochgesang Julie A.
Published: June 2022

In this commentary on the article by Kidd and Garcia, we point out that research on natural signed languages is an important component of the goal of broadening the database of knowledge about how languages are acquired. While signed languages do display some modality effects, they also have many similarities to spoken languages, both in function and in form. Thus, research on signed languages and their acquisition is important for a fuller understanding of the diversity of languages. Since signed languages are often learned in contexts other than those of typical input, it is also important to document the effects of input variation; we also see it as critical that input be provided as early as possible from models as fluent as possible. Finally, we call for removing existing barriers to training and education for would-be researchers, especially those interested in working on signed languages. Importantly, we advocate for the recognition of signed languages, for signed language research, and for the empowerment of community members to lead this research.
Identifying psychosocial challenges and introducing coping strategies for people with albinism
Authors: Zamani Varkaneh Mahya , Khodabakhshi-Koolaee Anahita , Sheikhi Mohammad Reza
Published: June 2022

Albinism refers to a group of genetic disorders that, following genetic mutations, lead to impaired melanin production, resulting in skin allergies and visual impairment in affected people. Visual impairment brings not only physical limitations and challenges but also many social problems, including psychosocial challenges, leading to different experiences in the lives of these people. To this end, using a qualitative content analysis approach, the present study aimed to identify psychosocial challenges and introduce coping strategies for people with albinism living in Tehran in 2021. The participants were people with albinism aged 20 to 40 years in Tehran. The participants were selected from among members of the Iranian Albinism Association (AMAL) using purposive sampling. The data were saturated through semi-structured interviews with 20 participants in the research sample. The collected data were analyzed using conventional content analysis. Analysis of the participants’ experiences revealed three main themes: (1) The challenges and difficulties of living with albinism, (2) welfare, specialized facilities, and support seeking, and (3) strategies for coping with psychosocial challenges. According to the findings, albinism, due to its limitations, brings many bitter and painful experiences in education, job finding, and marriage for affected patients. The condition is also associated with some limitations such as visual impairment affecting various aspects of the patient’s life and different developmental periods. Each person may have different interpretations of their challenges and thus seek unique strategies for coping with the challenges. The findings of this study can have some implications for mental health professionals and managers of relevant institutions and to become aware of the nature and complications of albinism, the challenges faced by people with albinism, and the special needs of these people. Findings from this study can be used to identify the relationship between albinism, the challenges of living with albinism, and the special needs of these individuals, by mental health professionals, related institutions, and psychosocial environments.
Adverse experiences resulting in emergency medical treatment seeking following the use of lysergic acid diethylamide (LSD)
Authors: Kopra Emma I , Ferris Jason A , Rucker James J , McClure Benjamin , Young Allan H , Copeland Caroline S , Winstock Adam R
Published: June 2022

Background:

Recreational lysergic acid diethylamide (LSD) use is growing in popularity amid increasing research interest on psychedelics and their possible therapeutic potential yet; the potent psychotropic effects of LSD may result in adverse reactions and behaviour.

Aims:

This study aimed to investigate the 12-month incidence and nature of LSD-related adverse experiences resulting in emergency medical treatment (EMT) seeking in an international sample of people reporting LSD use.

Methods:

We use data from the 2017 Global Drug Survey – a large anonymous online survey on patterns of drug use conducted between November 2016 and January 2017.

Results:

Out of 10,293 past-year LSD users, 102 (1.0%) reported seeking EMT, with a per-event risk estimate of 0.2%. Younger age, comorbid mental health conditions and higher frequency of use were associated with increased risk of EMT seeking. The most common symptoms were psychological, including anxiety, panic and confusion, with the most common explanatory factors cited by respondents being poor ‘setting’ and ‘mindset’. Most responders reported feeling back to normal within 24 h, but 11 participants experienced persistent issues after 4 weeks.

Conclusion:

The results suggest that LSD is a relatively safe drug in recreational settings. Adverse reactions are typically short-lived, self-limiting and psychological in nature. Sub-optimal set and setting were commonly reported as suspected contributory factors. Within clinical settings, patient screening, preparatory sessions and supervision should reduce these acute risks considerably.

Published: June 2022

Inflammation plays an important role in the pathogenesis of stroke. The differential expression of inflammatory and angiogenic factors in thrombi and plasma remain undefined. In this observational cohort study, we evaluated angiogenic factors and inflammatory cytokines, in cerebral thrombi, local cerebral plasma (CP), and peripheral plasma (PP) in patients with acute ischemic stroke. Protein analysis of thrombi, CP and PP were used to measure angiogenic and inflammatory proteins using electrochemiluminescence. Our data indicate that VEGF-A, VEGF-C, bFGF, IL-4, IL-13, IL-1β, IL-2, IL-8, IL-16, IL-6 and IL-12p70 were higher in the thrombi of acute ischemic stroke patients than in the CP and PP of stroke patients. Moreover, the protein levels of GM-CSF were lower in the PP than in the CP and the clot. Moreover, VEGF-D, Flt-1, PIGF, TIE-2, IL-5, TNF-β, IL-15, IL-12/IL-23p40, IFN-γ and IL-17A were higher in PP and CP than in thrombi. Our results show that cytokines mediating the inflammatory response and proteins involved in angiogenesis are differentially expressed in thrombi within the cerebral and peripheral circulations. These data highlight the importance of identifying new biomarkers in different compartments of the circulatory system and in thrombi that may be used for the diagnosis and treatment of stroke patients.

Motivations for Seeking Laser Tattoo Removal and Perceived Outcomes as Reported by Justice Involved Adults
Authors: Ojeda Victoria D. , Magana Christopher , Hiller-Venegas Sarah , Romero Laura S. , Ortiz Arisa
Published: June 2022

The goal of this study is to describe reasons for desiring removal of unwanted tattoos and self-reported outcomes among justice-involved adults (JIA) receiving free laser tattoo removal in Southern California. Between 2016 and 2021, JIA completed voluntary anonymous surveys at baseline ( n = 53) and follow-up ( n = 113) visits. Descriptive analyses were generated for quantitative items. Themes were identified from open-ended questions. Patients were predominantly male (74%) and most (81%) reported tattoo-related discrimination. Adjusted multivariate analyses showed that a higher number of domains in which patients reported tattoo-related discrimination was associated with having more tattoos to remove and citing reasons for removal related to employment and stigma by association (e.g., gang membership and police interactions). At follow-up, 48% of patients felt they were treated better in their community, and nearly a quarter of patients (25%) reported greater confidence and self-esteem. JIA seek tattoo removal due to stigma and discrimination. While JIA reported diverse benefits, tattoo removal should likely be considered as one element of comprehensive programing that addresses JIA’s diverse emotional, social, and economic needs. Longitudinal research is needed to clarify the long-term effects of tattoo removal for JIA.
New approach of maximum power point tracking for wind energy conversion system
Authors: Tounsi Souhir
Published: June 2022

This paper presents the modeling of wind energy systems using MATLAB Simulink. The model considers the MPPT (Maximum Power Point Tracking) technique to track the maximum power that could be extracted from the wind energy. The main contribution of our work lines in the choice of the Wind Energy Conversion System (WECS) components and the suitable MPPT technique. An innovating maximum MPPT technique is proposed. This technique combines the advantages of an ameliorated Perturb & Observe (P&O) control algorithm and the speed of Optimal Relationship Based (ORB) control algorithm to allow the MPPT controller output (duty cycle) adjusts the voltage input of a Buck-Boost converter to track the maximum power point. It searches for the system optimum relationship for maximum power point tracking and then controls the system based on this relationship. The main advantage of the proposed technique is that it does not require an anemometer or preknowledge of a system, but has an accurate and fast response to wind speed fluctuations. The MATLAB/Simulink simulation results show that the developed model components choice complies with cost and reliability constraints and confirm the validity and performance of the proposed control algorithm.
Subarea Partition Based on Correlation Analysis with Edge-Elimination Strategy Using Automatic License Plate Recognition Data
Authors: Ke Siping , Liu Wei , Lu Zhenbo , Rao Wenming , An Chengchuan , Xia Jingxin
Published: June 2022

To partition an urban network into several subareas (i.e., subarea partition) is a vital step for regional coordinated signal control. The correlation between intersections must be analyzed for achieving reliable subarea partition results. However, because of the incompleteness of spatial–temporal information in traffic data, previous studies merely explored the relationship between any intersections. Subarea partition considering the correlation of any pair of intersections remains a challenge in a large-scale network. This paper proposes a subarea partition method that integrates a novel correlation-degree model and the Newman fast algorithm with an edge-elimination strategy using automatic license plate recognition (ALPR) data. First, vehicle trips are extracted and a correlation-degree model is developed for measuring the relationship of any pair of intersections. Second, an edge-elimination strategy is proposed to generate candidate subarea partition solutions under conditions with different proportions of correlated edges. Finally, an optimal solution of subarea partition is identified by the ratios of ideal connected intersections to total intersections of different partition solutions’ correlation index (CI). The proposed method was implemented in a real-world urban network in Kunshan, China. The results show that the optimal partition solution can be obtained when the top 33% of correlated edges are maintained, and the ratio of ideal connected intersections’ CI is 72.35% with most of the intersections being connected, which demonstrates the rationality of the proposed partition method in large-scale urban networks.
Experiences of Puberty and Puberty Blockers: Insights From Trans Children, Trans Adolescents, and Their Parents
Authors: Horton Cal
Published: June 2022

This research explored experiences of transgender children and their families approaching and into adolescence, understanding experiences relating to puberty and puberty blocking medication. Data were drawn from 30 parents of 30 trans children and adolescents who at time of interview, were an average age of 11 years old. Parental interviewees were 90% white, 93% female, 100% cis, 60% heterosexual. Additional data were drawn from 10 trans children and adolescents, average age 12 years old. Interviews were held remotely, with families from across the UK. Rich qualitative interviews, averaging 2 hours for parents, and 25 minutes for children, covered aspects of family life, healthcare, and education. This article examined a sub-set of data on trans children and adolescents’ experiences of puberty, and of accessing, or trying to access, puberty blockers. Research received ethical approval from the author’s university. Data were analyzed through inductive reflexive thematic analysis. Three major themes are presented, relating to pre-pubertal anxiety; difficulties accessing blockers; and, for a minority who were on blockers, experiences of relief and frustration. The research has significant relevance for families, for healthcare professionals and policymakers, and for all seeking to protect trans adolescent mental health and well-being.
Historical biogeographic range shifts and the influence of climate change on ocean quahogs (Arctica islandica) on the Mid-Atlantic Bight

Published: June 2022

The Holocene, starting approximately 11.7 cal ka, is characterized by distinct periods of warming and cooling. Despite these known climate events, few temperature proxy data exist in the northwestern Atlantic Ocean. One potential record of past water temperatures is preserved in the marine fossil record. Shell growth of ocean quahogs ( Arctica islandica), a long-lived bivalve, can provide records of past environmental conditions. Arctica islandica habitat includes the Mid-Atlantic Bight (MAB), an area rapidly warming as a consequence of climate change. The Cold Pool, a bottom-trapped water mass on the outer continental shelf within the MAB, rarely rises above 15°C. Ocean quahogs inhabiting the MAB are confined to the Cold Pool as a consequence of an upper thermal limit for the species of ~15–16°C. Recently, dead A. islandica shells were discovered outside of the species’ present-day range, suggesting that the Cold Pool once extended further inshore than now observed. Shells collected off the Delmarva Peninsula were radiocarbon-dated to identify the timing of habitation and biogeographic range shifts. Dead shell ages range from 4400 to 60 cal BP, including ages representing four major Holocene cold events. Nearly absent from this record are shells from the intermittent warm periods. Radiocarbon ages indicate that ocean quahogs, contemporaneous with the present MAB populations, were living inshore of their present-day distribution during the past 200 years. This overlap suggests the initiation of a recent biogeographic range shift that occurred as a result of a regression of the Cold Pool following the Little Ice Age.

Published: June 2022

In water, sodium dichloroisocyanurate (NaDCC), a source for chlorine gas generation, releases free available chlorine in the form of hypochlorous acid, a strong oxidizing agent. NaDCC has been used as a disinfectant in humidifiers; however, its inhalation toxicity is a concern. Seven-week-old rats were exposed to NaDCC doses of 100, 500, and 2500 μg·kg−1 body weight by intratracheal instillation (ITI) to investigate pulmonary toxicity. The rats were sacrificed at 1 d (exposure group) or 14 d (recovery group) after ITI. Despite a slight decrease in body weight after exposure, there was no statistically significant difference between the control and NaDCC-treated groups. A significant increase in the total protein level of the bronchoalveolar lavage fluid (BALF) was observed in the exposure groups. Lactate dehydrogenase leakage into the BALF increased significantly ( p < 0.01) in the exposure groups; however, recovery was observed after 14 d. The measurement of cytokines in the BALF samples indicated a significant increase in interleukin (IL)-6 in the exposure group and IL-8 in the recovery group. Histopathological examination revealed inflammatory foci and pulmonary edema around the terminal bronchioles and alveoli. This study demonstrated that ITI of NaDCC induced reversible pulmonary edema and inflammation without hepatic involvement in rats.
How to measure service quality, customer satisfaction and loyalty of public library users: Application of library customer satisfaction index (LCSI) lite model
Authors: Oh Dong-Geun
Published: June 2022

This study develops a simplified Library Customer Satisfaction Index (LCSI Lite) for public libraries. Using data collected from questionnaires administered at four public libraries in South Korea, structural equation modeling was used to measure the scores. The suggested model was confirmed to have good acceptable fit, and that three dimensions of service quality (library personnel, library resources and user services, and facilities and equipment) influenced loyalty via customer satisfaction. After successful factor analysis and reliability testing, three items for library personnel, four for library resources and user services, two for facilities and equipment, two for customer satisfaction, and two for loyalty were analyzed. Means of each item in service quality were over 3.77, and those in satisfaction and loyalty were over 4.00. Direct and indirect effects of the dimensions of service quality were analyzed, with the effect of satisfaction on loyalty. LCSI Lite scores for the libraries as a whole (73.90 out of 100) and for each library were calculated using suggested formula. Finally, research and managerial implications, some recommendations and suggestions for further research, limitations, and conclusions were presented.

Authors: Parveen Afsa , Chaudhary Rashmi
Published: June 2022

The current hazardous problem of global climate change calls for adopting measures through which the environment can be protected. Consumer’s purchase patterns for energy-efficient products has a remarkable presence in the protection of the environment. Therefore, the primary objective of the present study is to get insight into determinants that influence the purchase intention of consumers for energy-efficient products. To achieve the objective, the influence of perceived benefits, perceived price, confidence, knowledge, attitude towards the environment has been checked on consumer attitude. Finally, the influence of perceived benefits and consumer attitude is checked on purchase intention. With this, the mediation effect of consumer attitude between perceived benefits and purchase intention; and the influence of control variables, namely gender and age were investigated on purchase intention. With Partial Least Square-Structural Equational Modelling (PLS-SEM), data from 273 respondents belonging to Northern India was analysed, and the results revealed that perceived benefits, confidence, knowledge and attitude towards the environment have a significant favourable influence on consumer attitude whereas the perceived price has a significantly negative influence on consumer attitude. Perceived benefits showed a low level of mediation. The present study focused explicitly on energy-efficient products that have an excellent contribution in keeping the environment healthier. Therefore, the study is valuable for the environment as well as for marketers of energy-efficient products for acquiring extensive market coverage.

Published: June 2022

Although Mycobacterium spp. often cause disease in domestic birds (chickens and companion birds), there are few data on avian tuberculosis in wild populations, especially in birds of prey. We describe here a case of a young adult female, free-living Eurasian griffon vulture ( Gyps fulvus) that was found dead. Granulomas were grossly evident in the lungs at autopsy, and tuberculosis was suspected. Ziehl–Neelsen staining revealed large numbers of intracellular acid-fast–positive bacteria within granulomas. Examination on Löwenstein–Jensen medium was negative, but mycobacteria growth indicator tube medium results were positive. For the molecular detection of Mycobacterium spp., the primer set IS901F and IS901R was used. Positive results were observed on gel electrophoresis, indicating the presence of Mycobacterium avium subsp. avium DNA. Although tuberculosis is not considered to be a common cause of death in wild birds, it undoubtedly deserves special attention because vultures are generally considered to be a species resistant to a large number of pathogens. Determination of the cause of death of griffon vultures is important for future conservation measures for this sensitive wild species.
System-level modeling and design method of an array of piezoelectric energy harvesters under typical ambient vibration
Authors: Zhang Yiran , Xiang Hongjun , Deng Housong , Zhang Xuebin , Zhan Jiawang , Shi Zhifei
Published: June 2022

Vibration-based piezoelectric energy harvesting has received significant attention recently due to its ability to convert vibration energy from the surrounding environment into electric energy to power wireless sensors. In this work, two typical types of vibration sources, that is, engine-induced floor vibration and train-induced bridge vibration, are considered. The array of piezoelectric energy harvesters (PEHs) is adopted to harvest the energy of vibration with different frequencies. The aim of this work is to give a stable system-level modeling method and present a method to select operating point for designing energy harvesters connected with nonlinear energy harvesting circuits under complex excitations. The system-level modeling method is based on Krylov’s subspace model order reduction algorithm. With the help of this method, the harvester can be modeled using conventional finite element software and co-simulated with nonlinear circuits at a system-level. The proposed method is validated using equivalent circuit method, equivalent impedance method and experiment results, and then employed to investigate the performances of harvesters under typical real vibrations. Finally, design suggestions for PEHs under different types of vibration sources are presented.

Published: June 2022

In order to reduce the impact force of the legged hydraulic-robot when it is driving on the ground, a new method based on magnetorheological technology is proposed for damping control of hydraulic mechanical legs in this paper. Firstly, the structure of hydraulic-driven leg with magnetorheological fluid (MRF) damper is designed, and the magnetic field simulation analysis of MRF damper is carried out to verify the rationality of magnetic circuit. Then the effects of different damping ratios on the dynamic performance of valve-controlled cylinder system are analyzed by theoretical modeling. Further, the co-simulation modeling of MRF damper and valve-controlled cylinder is established based on AMESIM to analyze the vibration reduction effect under impact force. Finally, the experiments of the hydraulic system designed in this paper are carried out under step load and triangular-wave load to obtain the system output displacement and pressure under two kinds of loads. Compared with the results without MRF damper, it is found that the new method can reduce the increase of pressure impact by 82% and almost eliminate the pressure fluctuation in the high pressure chamber of hydraulic cylinder.

Published: June 2022

Within scientific teams, a culture of community (the facilitation of shared values, goals, and an environment where individuals feel valued and want to engage in a team’s work) has implications for members’ learning and participation, and the team’s functioning, cohesion, and productivity. Drawing on 12 focus group interviews conducted over four years with 23 participants, we used an autoethnographic approach to examine how a research team developed a positive culture of community that influences its cohesion and productivity. We present six interconnected cultural practices that can foster a culture of community in settings where team-based learning and collaborations are required.

Mobile health (mHealth) interventions are increasingly used to support community health workers (CHWs) in low-and middle-income countries. As near-peers within their communities, the credibility of CHWs is sometimes questioned—a recognized barrier to their efficacy. Nested within a large, randomized-controlled trial, this qualitative study captured the experiences of South African CHWs, called “Mentor-Mothers,” using tablets and animated videos to promote exclusive breastfeeding. We conducted in-depth telephone interviews with 26 tablet-carrying Mentor-Mothers. We analyzed interview transcripts using a Grounded Theory approach, then developed a theoretical framework, based on an emerging theme, for understanding how tablet technology boosts the perceived credibility of CHWs. Tablet-carrying Mentor-Mothers described an increase in their perceived credibility, which they attributed to overt and signaling effects related to enhanced credibility of (1) their messages, (2) themselves as messengers, and (3) the program employing them. Mobile technology investments in CHWs could enhance their credibility, translating into meaningful investments in the health of under-served communities.
The Relationship Between Parental Career-Related Factors and Adolescents’ Ambivalence in Career Decision-Making: A Longitudinal Mediation Study
Authors: Li Shengnan , Pan Qianqian , Nie Yangang
Published: June 2022

Our current research aimed to investigate the mediating relationship between Parental Career-Related Factors, adolescents’ Career Decision-Making Self-Efficacy, and Ambivalence in Career Decision-Making with a total of 605 students from China. We collected data at three different time points, with a 6-month interval between each time point. Then we applied a Cross-Lagged Panel Model using data from all three waves, and the results showed that a higher level of support in Parental Career-Related Behaviors and Adolescent Parent Career Congruence measured at time 1 positively predicted Career Decision-Making Self-Efficacy at time 2; Career Decision-Making Self-Efficacy at time 2 negatively predicted Ambivalence in Career Decision-Making at time 3; and the indirect effect of support in Parental Career-Related Behaviors and Adolescent Parent Career Congruence on Ambivalence in Career Decision-Making was significant. Therefore, Career Decision-Making Self-Efficacy mediated the relationship between support in Parental Career-Related Behaviors and Ambivalence in Career Decision-Making and between Adolescent Parent Career Congruence and Ambivalence in Career Decision-Making. The implications, limitations, and future direction are discussed.

Authors: Rita Men Linjuan , Neill Marlene S. , April Yue Cen , Verghese Aniisu K
Published: June 2022

This study examined how the organizations’ use of mediated and interpersonal channels during change affects employees’ change-related outcomes. Specifically, the study proposed and tested a conceptual model that links organizations’ frequency of use of communication channels to perceived organizational communication transparency during change, employees’ feeling of uncertainty toward change, and employee affective commitment to change. Through an online survey of 1,034 employees who had experienced an organizational planned change in the United States, results showed that organizations’ frequent use of mass-mediated channels and interpersonal channels both positively influenced employees’ perception of communication transparency during change, with interpersonal channels showing stronger impact than mediated channels. Perceived change communication transparency negatively influenced employee uncertainty about change and positively influenced employee affective commitment to change. Perceived communication transparency during change mediated the effects of the organizations’ use of communication channels on employees’ uncertainty about change and affective commitment to change.

This is a reflection on The Score, a Research-Based Theater (RbT) project that has just begun, and some emerging ethical entanglements surrounding the work. The Score is a collaboration between First Nations and non-Indigenous artists and researchers, produced by ILBIJERRI Theatre Company—a leading First Nations theater company based in Melbourne, Australia. The goal is to create a community-engaged, participatory model for theater in health education that addresses sexual health for First Nations young people, to be delivered in schools, prisons, community centers and community health settings. Drawing on Indigenous and applied theater research methods, our article situates the discussion of ethics in RbT within the concept of relationality. Through a process of yarning (discussion), we explore the complexity of relations within the project and how relationality infuses all aspects of the project design. We argue that this approach is essential in ensuring respectful, accountable, and decolonial theater-research praxis.

Individuals with intellectual and developmental disabilities (IDD) are often excluded from conversations about sexual health; when included, well-meaning researchers and support workers often speak for individuals instead of creating opportunities for their voices to be heard. To support the sexual agency of people with intellectual disabilities, who refer to themselves as self-advocates (SAs), we embarked on a Research-based Theater (RbT) project, Romance, Relationships, and Rights, with the goal to address misconceptions of individuals with IDD and sexuality. Throughout the project, ethical tensions percolated from ableist assumptions about “legal capacity,” consent both on and off stage, and conflicting perspectives on aesthetics. Throughout this article, we discuss these ethical dilemmas and offer recommendations for future work with SAs in co-creating RbT through the lens of disability justice and critical disability studies.

Busulfan-based conditioning regimens are associated with serious toxicities and literature reports increased risk of toxicities when daily area under the curve concentrations exceed 6000 µM-minute. We implemented real time pharmacokinetic-guided therapeutic drug monitoring of busulfan for myeloablative conditioning regimens. The objective was to compare toxicity of intravenous busulfan before and after therapeutic drug monitoring implementation. The primary endpoint was incidence of hepatotoxicity. Medical records were retrospectively reviewed with weight-based dose Busulfan/Cyclophosphamide (BuCy) conditioning from August 2017 through March 2018 ( N = 14) and therapeutic drug monitoring from April 2018 through December 2018 ( N = 22). Recipients of busulfan therapeutic drug monitoring were younger than those receiving weight-based dose (median: 45 vs. 58 years, p = 0.008). No other baseline differences were observed. There was no difference in hepatotoxicity between therapeutic drug monitoring and weight-based dose (median 1 vs. 0 days, p = 0.40). In the therapeutic drug monitoring group, 45% of patients had increases and 41% had decreases in busulfan dose after Bu1. Repeat pharmacokinetic after Bu2 were required in 32% of patients. A pharmacokinetic dose monitoring program for myeloablative conditioning intravenous busulfan regimens may be considered a safe practice in stem cell transplant recipients. The majority of patients receiving pharmacokinetic-guided therapeutic drug monitoring required dose changes and therapeutic drug monitoring patients had no significant difference in toxicity compared to those receiving weight-based dose.
The Use of Standardized Patients as an Educational Strategy in Baccalaureate Psychiatric Nursing Simulation: A Mixed Method Pilot Study
Authors: Conway Kimberly A. , Scoloveno Robert L.
Published: June 2022

Objective:

Prior psychiatric simulation experiences required our nursing students to role-play in an unknown area of nursing. Students confidence, clinical satisfaction, and use of clinical skills were negatively impacted leading to unmet course objectives. The aim of this pilot study was to strengthen our baccalaureate senior nursing students’ simulation experience in their psychiatric nursing course with the use of standardized patients (SPs) instead of student role-play and measure the impact of this strategy on students’ learning, satisfaction, and confidence in an unfamiliar area of nursing.

Methods:

A mixed method explanatory sequential design was used. Participants consisted of a convenience sample of senior nursing students enrolled in their psychiatric nursing course. A quantitative simulation tool and a four-item questionnaire were analyzed after completion of the simulations ( n = 47).

Results:

Findings of this study identified greater than 80% of students had increased level of learning, confidence, and satisfaction with the SP simulation experience. Nurse faculty were able to overcome simulation barriers, that is, a patient hearing voices, non-verbal signs of depression, and evaluate students meeting course learning outcomes.

Conclusions:

Findings from this study highlight students’ positive simulation experiences. Using SPs as an educational strategy can be effective for students to reach competency, achieve higher knowledge, and improve confidence. It is believed the use of SPs as a simulation strategy in psychiatric nursing will assist students with clinical judgment and better prepare them to meet the needs of vulnerable persons with psychiatric conditions.

Background:

CVCs are defined ‘complex’ when they are inserted through non-conventional accesses or positioned in non-usual sites or substituted by IR endovascular procedures. We report our experience in using diagnostic and interventional radiology techniques for complex CVC insertion and management; we recommend some precautions and techniques that could lead to long-term availability of central venous access and to avoid non-conventional sites CVC insertion.

Methods:

We retrospectively evaluated 617 patients, between January 2010 and December 2019, (mean age 71 ± 13; male 448/617), treated in our department for insertion of tunnelled CVC for haemodialysis.

Results:

Among 617 patients, 241 cases (39%) are considered ‘complex’ because they required either a PTA with or without stenting to restore/maintain venous access or had an unusual positioning site or required unconventional access. A direct correlation between CT angiography and PTA ( r = 0.95; p-value <0.001) and an inverse correlation between CT angiography and unconventional ‘rescue’ access ( r = −0.92; p-value <0.001) were found.

Conclusions:

Precise pre-operative planning of treatment in a multidisciplinary setting and diagnostic and interventional radiology procedures knowledge allows reducing complex catheterisms in haemodialysis patient.
The fallacies of non-agility: Approaching organizational agility through a dialectical practice perspective
Authors: Armstrong Ryan , Manitsky Daniel
Published: June 2022

Complexity, paradox, tension, and contradiction are increasingly seen as permeating all aspects of organizational life. Yet despite ongoing advancement, both our understanding of the nature of complexity and how to use this increased appreciation of it in practice are still developing. In this spirit, this article considers organizational agility and how to achieve it. Here, current discussions of organizational agility have failed to sufficiently address the fundamental tensions inherent in learning stemming from conflicting goals and incentives, evident in an ongoing discussion of theory-informed approaches for bringing about organizational agility. In this article, we claim that incorporating a dialectical perspective of learning would provide a means of understanding the successes and failures of practices aimed at bringing about agility. We consider the maligned dialectic, four fallacious ways of thinking that hinder agility, and the extent to which these can be overcome. As evidence, we present a case of Agile implementation in which one of the authors acted as a consultant and involving a large-scale social change. Considering this from a dialectical perspective, we discuss ways that dysfunction in achieving agility might be reduced through disruptive interventions, such as Agile.
