Constructivist Correlates to Anniversary Reactions Across Bereavement and Sexual Violence
Authors: Bruce Madeline J. , Handal Paul J.
Published: July 2022

Anniversary reactions are an accepted part of bereavement, but recent research demonstrates that ARs can be seen across many traumatic events. The present study explores how constructivist theories could characterize ARs caused by the death of a loved one or sexual violence. N = 234 women answered questionnaires regarding their posttraumatic adjustment, meaning made of the trauma, trauma centrality, and social validation or invalidation of their trauma. Our data demonstrate that ARs are marked by statistically and clinically significant increases posttraumatic stress disorder symptoms. Participants in this study did not endorse significant posttraumatic growth during their AR. The women in the sexual violence group endorsed more social validation and invalidation as well as less meaning made of their trauma compared to the bereavement group. There were no group differences regarding trauma centrality. Results of this study provide empirical support for an understudied yet significant phenomenon and directions of future study.
Food security, food insecurity, and Canada’s national food policy: Meaning, measures, and assessment
Authors: Deaton B. James , Scholz Alexander
Published: July 2022

We review the Canadian federal government‘s recently enacted Food Policy for Canada (FPC). Three arguments are developed. First, the development and vision statement of the FPC implies that improving Canadian food security is a specific objective of the policy. Second, if assessed by the measure of food insecurity promulgated by Statistics Canada, the effectiveness of the FPC in reducing Canadian food insecurity will primarily depend on the extent to which it improves household incomes and/or lowers food prices. We evaluate the current programmatic content by these criteria. Third, and related to the second point, we argue that the variation in the severity of food insecurity is an important consideration in assessing the effectiveness of FPC programs in reducing food insecurity as measured by Statistics Canada. Finally, we combine these three arguments into a simple figure/heuristic that can serve as a guide to the assessment and development of FPC programs seeking to enhance food insecurity in Canada.

Published: July 2022

Since training/competition loads must be quickly assessed and interpreted to inform exercise prescription, big data should be simplified through multivariate data analysis. Our aim in the present research was to highlight which variables from big data analyses provided the most relevant information for describing the behavior of top-level futsal players in their different playing positions (i.e., goalkeeper, defenders, wingers, and forwards). We collected data from four top-level Spanish teams that participated in the final rounds of a national tournament. Through principal component analysis (PCA) we grouped 6–9 variables in 3–4 PCs that explained 62–81% of total variance, depending on playing positions. The most relevant variables explaining goalkeepers’ performance were accelerations per minute, maximum acceleration (m/s2), 5–8 impacts per minute, and < 3 takeoffs per minute. Defenders’ behavior was best explained by absolute distance covered from 6-12 km/h (m/min) and from 18-21 km/h (m/min), from 5-8 landings per minute, and > 8 landings per minute. Wingers’ and pivots’ performances were mainly explained by accelerations and decelerations, together with a high level of aerobic endurance (especially for wingers). These findings allow for individualized training and game analysis.
Terminal sliding mode observer based–asymptotic tracking control of electro-hydraulic systems with lumped uncertainties
Authors: Li Shuai , Guo Qing , Yan Yao , Shi Yan
Published: July 2022

Since the existence of lumped uncertainties caused by uncertain parameters and unmeasured external load, the disturbance suppression is always a significant issue in research of electro-hydraulic system (EHS). In this paper, a type of terminal sliding mode observer (TSMO) is introduced for EHS, based on which the disturbances can be converged in a finite time. Then, based on TSMO, a controller is designed via recursive backstepping method to realize the displacement tracking control of EHS. Finally, simulated results are given to verify the feasibility of the proposed theoretical conclusions and a series of contrast experimental results are also given to illustrate the better performance of TSMO and proposed control strategy than others.
Contextual dependency and overuse of estar in the acquisition of Spanish copula verbs
Authors: Aveledo Fraibet , Sanchez-Alonso Sara , Piñango Maria Mercedes
Published: July 2022

The delayed acquisition of Spanish ser and estar is generally understood as rooted in the cognitive demands imposed by the integration of semantic-pragmatic and world-knowledge factors associated with their lexical meanings. Here we ask (1) what is the nature of this language world-knowledge integration? and (2) what is the developmental trajectory including its age distribution? We examine Spanish copula production and comprehension in 142 children (age range: 4–12 years) and 26 adults. Using two tasks, sentence-choice (comprehension) and cued-production (production), we test the hypothesis that estar use is constrained by an ability to construe an alternative to the copula predication; an ability that develops with life experience. We test estar/ ser use in two contexts: alternative-supporting, favoring estar use; and alternative-neutral, neutral regarding estar use, and possibly favoring ser use. The results show that for comprehension, children do not reveal adult-level sensitivity to context, exhibiting instead over-selection of estar sentences. For production, all children over-produce the estar sentence, even after having just chosen the ser counterpart. However, in this task, the 10- to 12-year-olds do behave similarly to adults and differently from 4- to 6-year-olds, consistent with our hypothesis. Alternative construal requires exposure to entities and properties in a variety of situations; exposure that older children are more likely to exhibit. Collectively, these results (1) support the properties of estar use hypothesized to underlie the language-world-knowledge integration, and (2) delineate a potential developmental trajectory whereby mastery of the copula may not begin to manifest until 10–12 years of age, not because of any one linguistic factor but rather due to specific world-knowledge exposure constraints.
“We Don’t Live In Jungles”: Mediating Africa as a Transnational Socio-Spatial Field
Authors: Schmidt Sandra J.
Published: July 2022

Background/Context:

Amid rising immigration from the African continent to the United States, researchers have begun to explore the transnational identities and networks of African immigrants. There is a small body of literature about whether educational supports for immigrant youth are differentiated to address the particularities of African immigrant youth.

Purpose/Objective/Research Question/Focus of Study:

Transnational theories presume that subjects use social networks to connect home and diaspora. They are encountering both perceived and lived social spaces to navigate belonging in and across space. This study asks, “How do youth from the African continent mediate transnational belonging in NYC?” Studying the experiences of youth has implications for the curricular and extracurricular spaces of schools wherein newcomer youth navigate how to belong in the diaspora.

Population/Participants/Subjects:

Research participants are 19 newcomer African youth from Centrafrique, Cote d’Ivoire, Ethiopia, Guinea, Mauritania, Niger, and Senegal. Most of the youth are multilingual and speak French and English as third or fourth languages.

Research Design:

This qualitative study draws from participatory action research and visual methods. The study was conducted with Sankofa Club, a weekly afterschool student-led club. In the club, students responded to stereotypes by producing websites about the continent and carrying out research within the club to compare their homes and share their migration stories.

Findings/Results:

The article presents “Africa” as a Mediated Transnational Space, produced by hegemonic structures, that youth mediate as they connect homes. The study finds that youth wrestled with their identification as African. It reexamines transnationalism and positions Africa as a social field through which youth are produced (come to be) as African subjects, redress their belonging to that field by contributing their own symbols and experiences, and use it as they navigate an Africa-in-NYC that does not adhere to continental boundaries.

Conclusions/Recommendations:

Educators can support the belonging to home, Africa, and the United States by representing Africa as a generative space in curriculum and social practices.
Do Migrant Parents’ Income or Relationships With Their Left-Behind Children Compensate for Their Physical Absence?
Authors: Khalid Sabika , Tadesse Endale , Lianyu Cai , Gao Chunhai
Published: July 2022

Parental migration from rural to cities in China is causing millions of children to be left behind or to live without parental care, support, and guidance, which violates the Convention on the Rights of the Child. This national phenomenon has consequences for the household registration system, known as the hukou system, which is meant to restrain internal migration. These consequences may result in economic and social imbalances. However, a noticeable number of children have been completely or partially left behind by their parents in villages, and as a result, their relationship with their parents and their academic attainment are weak. In particular, this study examines whether migrant parents can improve the academic performance of their Left-Behind Children (LBC) by strengthening their relationship with their children or by sending adequate remittances to the village household. Astonishingly, the structural equation model (SEM) results indicate that LBCs from both parents migrating households are the more privileged groups, although the study underlines that still, all LBC are disadvantaged compared to non-LBC.
From theory to practice: Student-centered pedagogical implementation in primary music demonstration lessons in Guangdong, China
Authors: Zhang Le-Xuan , Leung Bo-Wah , Yang Yang
Published: July 2022

Demonstration lessons are used in China to provide models of quality music instruction. However, to date, no research has been done on the quality of demonstration lessons and how this relates to the improvement of school music education in China. This content analysis provides an insight into China’s music demonstration lesson implementation and its contextual adaptation for student-centered education (SCE). A total of 19 music demonstration lessons over 760 minutes have been examined, using both a systematic observational method and a qualitative thematic analysis method to look at in-class behavior and interaction. An analysis of data reveals that: (a) direct content-driven activities are still taking dominant roles in class, (b) students’ individuality is seldomly promoted, (c) activity-based lesson structures have become prevalent, and (d) sequential patterns under a behaviorist perspective still can be seen in China’s demonstration lessons. Although findings may not necessarily represent exactly what is happening in a regular school setting and it reveals a different adaptation of SCE compared to an international perspective, it serves as a starting point for understanding the official educational views of China and a different angle in perceiving the adaptation of SCE in practice under China context.

We considered global impact based on manuscript citations, times countries or specific global regions appear in titles, country affiliation of authors, and sole or collaborative authorship. We further examined 7,348 individual words contained in the published paper titles. Data showed a chronological shift from sole to collaboratively authored manuscripts and an increase in the number of words used in titles (ranging from 2 to 31). Citations ( N = 9,713), different countries ( N = 158), and global regions ( N = 40) in titles, and country affiliation of authors ( N = 47) represent a strong global impact. Substantive keywords used in two or more titles align well with the founding principles and purposes of the commission. Perhaps the most salient finding is the manner in which collective data in this study supports and reinforces the extraordinary aspirations and intent of the ISME RC from 1968 to 2018 showing the past, present, and continued necessity of this unique organization of the ISME.
Prevalence of and factors associated with sarcopenia among elderly individuals with hypertension
Authors: Xing Enwang , Wan Chunxiao
Published: July 2022

Purpose

Sarcopenia is a major health problem in community-dwelling elderly individuals. Hypertension is postulated to aggravate sarcopenia. The present study was performed to estimate the prevalence of and factors associated with sarcopenia among elderly individuals with hypertension.

Methods

This study involved 165 Chinese individuals with hypertension aged ≥60 years who were evaluated for sarcopenia using the Asian Working Group for Sarcopenia criteria. Data on their sociodemographic information, physical illnesses, and clinical and functional status were collected.

Results

The overall prevalence of sarcopenia among elderly individuals with hypertension was 20.2%. The factors significantly associated with sarcopenia were an age of ≥70 years (adjusted odds ratio (OR), 3.01; 95% confidence interval (CI), 1.17–5.39), diabetes (OR, 4.45; 95% CI, 1.32–11.16), osteoporosis (OR, 2.52; 95% CI, 1.13–5.37), drinking (OR, 3.28; 95% CI, 1.26–7.85), and a body mass index of 24.0 to 27.9 kg/m2 (OR, 0.74; 95% CI, 0.59–0.91).

Conclusions

This study revealed a very high prevalence of sarcopenia among elderly individuals with hypertension (20.2%). Sarcopenia may be associated with advanced age, drinking, diabetes, the body mass index, and osteoporosis. The longitudinal relationship between clinic visits and sarcopenia should be further evaluated.

Authors: Tsai Hsiang-Lin , Chen Po-Jung , Chen Yen-Cheng , Li Ching-Chun , Chang Tsung-Kun , Su Wei-Chih , Yin Tzu-Chieh , Huang Ching-Wen , Wang Jaw-Yuan
Published: July 2022

Objective

The UGT1A1*28 polymorphism reduces UGT1A1 enzymatic activity, which may increase the risk of severe toxicity in patients who receive standard-dose irinotecan, such as severe neutropenia and diarrhea. This real-world study assessed the optimal irinotecan dose in terms of efficacy and toxicity in metastatic colorectal cancer (mCRC) patients homozygous for the UGT1A1*28 polymorphism and receiving FOLFIRI plus bevacizumab or cetuximab as first-line therapy.

Methods

We analyzed toxicity and treatment outcomes in seven mCRC patients who were homozygous for UGT1A1*28 and received FOLFIRI plus bevacizumab or cetuximab, with an initial irinotecan dose of 120 mg/m2.

Results

Six of the seven patients tolerated 120 mg/m2 irinotecan without requiring dose reductions in subsequent cycles. The overall response and disease control rates were 43.0% (3/7) and 71.4% (5/7), respectively. The median progression-free survival and overall survival were 11.0 and 33.0 months, respectively. Only one severe adverse event, grade III neutropenia (2.5%), was observed.

Conclusions

mCRC patients homozygous for the UGT1A1*28 allele can tolerate irinotecan at an initial dose of 120 mg/m2 with favorable oncological outcomes and toxicity profiles. Further prospective studies are warranted to optimize irinotecan-based chemotherapy in these patients.
Management of medullary carcinoma of the thyroid: a review
Authors: Jayasinghe Ravindri , Basnayake Oshan , Jayarajah Umesh , Seneviratne Sanjeewa
Published: July 2022

Medullary thyroid carcinoma (MTC) is an uncommon malignancy of neuroendocrine origin derived from the parafollicular C cells. Although infrequent, the interest in this cancer exceeds its incidence owing to its distinctive features and its characteristic association with other endocrine tumors. Although the majority of MTCs are sporadic, hereditary varieties occur in isolation or as a part of multiple endocrine neoplasia type 2 syndrome (MEN 2). Currently, complete surgical resection of the tumor and nodal metastases with a curative intent remains the mainstay of therapy. The role of adjuvant therapy is limited, although radiotherapy and newer targeted therapies are routinely used for metastatic disease. The lack of consensus in the available guidance regarding the most appropriate diagnostic, therapeutic and follow-up strategies has caused substantial variability in clinical practice. Therefore, this review summarizes the latest available evidence and guidelines on the management of MTC with an emphasis on diagnosis, surgical treatment and follow-up.
Identifying the Adaptability of Different Control Types Based on Delay and Capacity for Isolated Intersection
Authors: Danesh Ali , Ma Wanjing , Wang Ling
Published: July 2022

In urban road networks, intersections are the main bottlenecks. Selecting an appropriate intersection control type can significantly improve the performance of an isolated intersection. Therefore, this paper offers recommendations for selecting the most efficient control type among two-way stop control, signalized intersection (SIG), roundabout (RB), and signalized roundabout (SIGRB) based on capacity and delay. The procedure to calculate delay and capacity is taken from the Highway Capacity Manual 6th edition (2016), or developed separately if needed. Two flow patterns are assumed: fixed and time-varying demand. For fixed demand, the results show that SIGRB outperforms other control types both in capacity and delay at higher demand levels. It was also observed that increase in left-turn ratio increases the delay and decreases the capacity of all control types while its impact on SIGRB was the least. Considering time-varying demand, traffic volume fluctuates over the 5-h period of the analysis. It was found that using both RB and SIGRB together creates significantly less delay compared with the other options. Additionally, using RB provides less variability in delay when there is fluctuation in demand. The major finding of this research is that RB and SIGRB have potential benefits for delay in conditions of (i) high traffic volume, (ii) high left-turn ratio, and (iii) demand fluctuation. Furthermore, it is suggested that SIG should be used if the left-turn ratio is relatively low. The results of this study could help decision-makers to choose the best control type for an isolated intersection under various traffic conditions.
Psychometric Properties of the Turkish Adaptation of Teacher Emotions Scale
Authors: Calik Basak , Capa‐Aydin Yesim
Published: July 2022

The current research investigated the psychometric characteristics of the Turkish adaptation of the Teacher Emotions Scale (TES). Study I included a sample of 164 Turkish middle school teachers, and Study II included a sample of 222 mathematics teachers. The three-emotion factor model was confirmed in both studies with satisfactory reliability estimates. This model was invariant across gender. In addition, the latent mean structure analyses revealed no significant differences in teacher emotions by gender. Regarding convergent validity, teacher emotion scores showed a significant relationship with teacher self-efficacy. Thus, the Turkish version of the TES demonstrated sound psychometric characteristics for measuring teachers’ academic emotions in educational contexts.

Alors que les expériences de visite en ligne ne cessent de s’enrichir, la plupart des chercheurs et des praticiens évaluent la valeur perçue d’une expérience de navigation sur le web par le biais de mesures restrictives et développées à l’origine dans des environnements offline. Si l’approche Experiential Value Scale ( EVS) est la seule mesure spécialement conçue, il y a 20 ans, pour appréhender les différentes facettes de la valeur perçue d’une expérience online, elle n’a été utilisée qu’à deux reprises dans ce contexte ; alors même qu’elle est couramment employée pour étudier la valeur perçue d’une offre offline. Cette note de recherche vise ainsi à apprécier la pertinence et la robustesse d’ EVS dans un contexte online. A l’issue d’une double réplication de cette mesure, appliquée à la visite des sites web des châteaux de Chambord et Chenonceau (N=914), les résultats montrent l’intérêt et les conditions d’usage de cette approche, qui permet d’appréhender plus finement les sources de valeur perçue d’une expérience de visite en ligne.

Quantitative analysis of vehicle plane motion system stability
Authors: Meng Fanyu , Shi Shuming , Zhang Boshi , Liu Xiaojiao , Lin Nan
Published: July 2022

The classical conclusions about the vehicle stability are usually drawn from the 2-DOF vehicle model. As more and more researchers begin to explore the complex dynamic characteristics of nonlinear and high degrees of freedom vehicle plane motion system, it is of value to intuitively reveal the global dynamic characteristics by objective quantitative indicators. Moreover, a new quantitative indicator, dissipation of energy, was proposed in 2021, and it is also worth further analyzing its rationality. For the above purposes, first of all, this paper briefly introduces the difference between the 2-DOF model and the high degree of freedom (≥3) model based on previous work. Secondly, this paper objectively discusses the stability characteristics of high degrees of freedom vehicle system from different aspects (dissipation of energy, longitudinal velocity, tire sideslip angle, convergence time) for the first time. In addition, the relationship between each indicator is systematically compared with the dissipation of energy, and their advantages and disadvantages are explained. Therefore, the main contributions of this paper are as follows: (1) This paper supplements previous conclusions on the dynamic characteristics of high-DOF vehicle plane motion system and helps researchers better understand the global dynamic characteristics from different perspectives. (2) This paper supplements previous discussions on the rationality and effectiveness of dissipation of energy method, and objectively reveals the relationship between dissipation of energy and stability. (3) This paper establishes a link between qualitative and quantitative methods. The vehicle system dynamics characteristics are presented from a variety of quantitative perspectives for the first time, supplementing the relevant research in the field of dynamics quantitative indicators.

Published: July 2022

Experimentally and theoretically, this paper combines thermodynamics, aerodynamics and structural dynamics to give a universal dynamical model of dual-chamber air springs, with physical meanings of each stiffness and damping term. An indicator experiment was designed to verify the theory proposed in this paper. The experimental results show that the dynamic stiffness model can well reflect the hysteresis characteristics and the variable stiffness characteristics of the dual-chamber air spring. It can also clearly reveal the frequency dependence of the dynamic stiffness. Finally, based on the derived model, the influence regulation of each parameter term on the dynamic stiffness amplitude and hysteresis phase angle is given numerically. The results show that each term can influence different dynamic characteristic of the dual-chamber air springs. The conclusions of this article can provide positive guidance for the vehicle dynamics matching and design of air springs.

Published: July 2022

The present investigation analysed the effect of mould vibration using an indigenous vibrating setup on the physical, metallurgical and mechanical properties of die cast A308 alloy. The alloy was vibrated at a constant amplitude of 31µm at 75, 100, 125 and 150 Hz. The work aims to generate more nucleation sites during melt solidification by fragmenting dendrites and Si particles. To examine the changes in metallurgical characteristics, α-Al, secondary dendritic arm spacing, length, width and aspect ratio of eutectic Si particles were studied using optical microscopy, scanning electron microscopy and X-ray diffraction analysis. It was observed that the size of α-Al, secondary dendritic arm spacing, length, width and aspect ratio of eutectic Si particles were decreased by 47%, 53%, 65%, 12% and 61%, respectively. Whereas, the shape factor and density of the alloy were enhanced by 25% and 1.62% compared to stationary cast samples because of mechanical vibration treatment at an optimum frequency of 100 Hz. Mechanical testing findings demonstrated a 13%, 20%, 15% and 20% increase in the parameters such as yield strength, ultimate tensile strength, percentage elongation and microhardness at 100 Hz when compared to the stationary cast sample. Grain refinement, uniformity of structure, improvement in the morphology of metallurgical characteristics, decreased porosities and subsequent increase in density were all factors that contributed to the improvement. Tensile test samples with scanning electron microscopy fractography demonstrated transgranular brittle fracture and a few ductile rips.
Robust optimization of the aerodynamic design of a helicopter rotor blade based on multi-fidelity meta-models
Authors: Salh Eddine Derbal , Smail Khalfallah , Mahfoudh Cerdoun , Lyes Tarabet
Published: July 2022

Robust optimization (RO) of designs becomes indispensable to deal with inherent manufacturing uncertainties. Yet, RO is still too expensive to solve complex problems such as the design of helicopter rotor blades. A promising way to reduce this cost is to use the multi-fidelity meta-model-based optimization (MFMBO), which combines low fidelity models (LFM), high fidelity models (HFM), meta-models, design of experiment (DoE), and optimization techniques. The field of MFMBO is not been completely explored despite the high number of proposed strategies. This paper contributes to the MFMBO cost-effectiveness improvement by proposing a new strategy. The main feature of the latter is the mutual adaptive refinement of the HFM and LFM DoE sets. A new idea is proposed to generate initial nested DoEs, which is implemented using an ordinary and an optimal Latin Hyper Cube method. These DoEs are refined adaptively and mutually using an improved MaxMin-distance criterion. The expensive HFM is used only to define a correction C of the LFM. C is used to adjust LFM evaluations during MBO. Meta-models are constructed using the Radial Basis Functions technique. The strategy is tested with two RO techniques, namely, the Non-Dominated Sorting Genetic Algorithm (NSGA-II) and the Multi-Objective Evolutionary Algorithm Based on Decomposition (MOEA/D). The implemented strategy is validated on three different mathematical benchmarks, compared with four different MFMBO strategies and applied on a helicopter rotor blade. This validation shows that the proposed MFMBO is competitive and can produce solutions as accurate as the HFM-based MBO while reducing significantly the overall computation time (up to 40%).

Published: July 2022

Human monkeypox (MPX) is a zoonotic endemic disease in regions of Africa caused by the monkeypox virus, with a recent outbreak in several non-African countries. We report a case of a 24-year-old male patient with a concurrent diagnosis of MPX and acute HIV infection who presented to our Emergency Care Dermatology Clinic with disseminated papules throughout the trunk, face and genital area. On the perianal area, several grouped umbilicated whitish papules in a kissing lesion configuration could be seen. Laboratory workups were consistent with recent HIV infection, and swab samples from the lesion surfaces were positive for monkeypox virus. We provide novel information on the clinical presentation of MPX, expanding the data pool of the clinical manifestations of which health workers should be aware.
Tuned mass systems with the Bouc-Wen and a hybrid hysteresis
Authors: Rathore Khogesh K , Biswas Saurabh
Published: July 2022

Tuned-mass-dampers are extensively used in physical systems in order to reduce the dynamic response of the primary structures. The damping in a tuned-mass-damper system plays a significant role. In many engineering systems, we see damping is hysteretic in nature. Tuned-mass systems with nonlinear hysteretic damping are mathematically challenging. In this paper, tuned mass systems with rate-independent hysteresis are studied. In particular, first we study tuned mass systems with the famous Bouc-Wen model, and then we study tuned mass systems with the Bouc-Wen model and a recently developed scalar hysteresis model in parallel. Numerical approaches are used to study the dynamic responses of the systems. The sine sweep responses show two resonance peaks. The sine sweep responses indicate the amplitude versus frequency of the systems. The numerical results obtained for two different hysteretic dampers are compared.
The meaning and potential of a human rights-based approach to climate change post-Sharma
Authors: Walker Scott
Published: July 2022

Against the background of the Sharma decisions, this article considers the meaning and potential of a human rights-based approach to climate change for Australia. It examines the human right to a healthy environment as recently recognised by the United Nations Human Rights Council and considers how recognition of this right has shaped climate litigation. Beyond formal legal recognition and climate litigation, this article argues that there is significant potential for a human rights-based approach to climate change in driving a rethinking of policy making which places people on the frontline of the climate crisis at the centre of responses to climate change and treats them as rights-holders rather than victims of a hostile climate.

Authors: Martinsson Eva , Garmy Pernilla , Einberg Eva-Lena
Published: July 2022

The coronavirus 2019 (Covid-19) pandemic has affected both the private and public lives of people worldwide. Countries have chosen different strategies to reduce the spread of infection, including school closures and distance learning. This study aimed to describe school nurses’ perceptions about the wellbeing of students during the Covid-19 pandemic in Sweden. Interviews in five focus groups and one individual were conducted with 17 school nurses in Sweden. The interviews were analyzed using a qualitative content analysis. According to the school nurses’ perceptions, students were concerned about spreading infection, becoming infected themselves, their academic performances, and longing for socialization. The change in the school situation involved a slower pace and less anxiety for some students, more or less physical activity, and an increase in screen time.
Evaluating the Relationship Between Performance on a Multiple-Choice Examination and Common ABA-Based Procedures

Published: July 2022

To ensure the quality of training, skills developed and maintained, and expected standards for behavior analysts, several systems have been put into place across the years. Of these systems, perhaps the most widespread was the development of the Behavior Analyst Certification Board in 1998. Once all requirements are met, the final determinative step in obtaining certification is a multiple-choice examination. The use of a multiple-choice examination as the final determinative step in obtaining behavior analytic certification may create some concerns for behavior analysts. Identification of a positive correlation between the multiple-choice examination and performance may help ameliorate these concerns. The purpose of this study was to evaluate any potential correlations between scores on a popular commercially available prep examination and basic applied behavior analysis (ABA)–based autism intervention procedures with 25 professionals. Overall, the results indicated that multiple-choice examination scores were not significantly correlated with any assessments of performance.
Methods to examine omitted variable bias in hedonic price studies
Authors: Boto-García David
Published: July 2022

Many studies use the hedonic pricing method to uncover consumers’ willingness to pay for accommodation characteristics in the hospitality industry. In most empirical applications using cross-sectional data, implicit prices might be biased if omitted time-invariant variables correlate with observed attributes. This paper proposes a set of diagnostic checks to inspect the potential bias in the estimates through exploiting repeated information for the same accommodations. Due to the limitations imposed by standard fixed and random effects panel regressions, we advocate for the use of Mundlak and Hausman–Taylor estimators. The proposed methods are applied to a study of Airbnb hedonic prices in Ibiza using a 14-month time window. In doing so, we document a novel finding: Superhosts set lower prices conditional on time-invariant quality.
Experimental assessment of proposed seismic strengthening scheme for adobe structures
Authors: Rafi Muhammad Masood , Khan Muhammad Saad , Rais Adnan , Ahmed Shoaib
Published: July 2022

A new scheme of seismic strengthening of adobe structures has been proposed in this paper. The scheme involves horizontal and vertical bands of steel wire mesh plastered with cement-sand mortar. The effectiveness of the proposed scheme is assessed by dynamically testing a half-scale model of the adobe structure on a shaking table. The acceleration time history record of the 1995 Kobe earthquake was used to simulate the ground motion for the strengthened model which was increased sequentially in increments of 25% of peak ground acceleration (PGA). Initial (hairline) cracks were observed in the in-plane wall of the model at a PGA of 0.439 g. Although the out-of-plane walls also sustained damages, the in-plane walls were the most damaged parts of the structure. The proposed strengthening method reduced the torsional irregularity of the structure. It also increased strength, ductility and energy dissipation capacities of the walls. The data of observed structural damages and building drift were used to propose four performance levels for the strengthened adobe structures corresponding to the applied PGAs of ground motion.

Published: July 2022

Air embolic signals detected in the intracranial arteries using transcranial Doppler after intravenous injection of agitated saline bubbles indicate right-to-left cardiac shunting. They prove that emboli from venous sites can bypass the lungs and flow to the intracranial arteries. The Valsalva maneuver immediately after an intravenous injection of agitated saline bubbles helps the air bubbles pass through the shunt. If the air embolic signal appears in the intracranial arteries without the Valsalva maneuver, the shunting is highly significant to the etiology of embolism. Transcranial Doppler to detect air embolic signals after intravenous injection of agitated saline bubbles may not be mandatory to diagnose and treat patent foramen ovale; however, as with echocardiography, transcranial Doppler is considered a noninvasive, convenient, and low-cost investigation. The test should be helpful to confirm the significance of the corresponding patent foramen ovale.
Selfies in Auschwitz: Popular and contested representations in a digital generation
Authors: Feldman Jackie , Musih Norma
Published: July 2022

Selfies at Auschwitz have become increasingly popular, and have generated agitated public debate. While some see them as an engaged form of witnessing, others denounce them as a narcissistic desecration of the dead. We analyze the taking, composition, and circulation of several of the most popular selfies of Auschwitz and the online reactions to them. The practice of selfies marks a shift from witness to witnessee and from onsite to online presence. Yet it also builds on previous practices: photography, postcards and souvenirs, the affordances of the architecture of the memorial site, the bodily presence of the survivor-witness as mediator of the Holocaust, and the redemptive value assigned to the physical presence of the visitor as “witness of the witness.” We suggest that the combination of continuities with the past alongside the radical break with previous witnessing practices empowers selfie-takers, while arousing the indignation of gatekeepers of Holocaust memory.

The aim of this study was to confirm the anti-inflammatory effect and explore the adverse effects and underlying mechanisms of Prunella vulgaris L., which has been extensively used for hundreds of years in East Asia. Network pharmacology studies predicted that glucocorticoids (GCs), GC-targeting molecules, and brain-derived neurotrophic factor (BDNF) were intensively involved in the anti-inflammation and glucose intolerance. To attest the effects and underlying mechanisms, C57 male mice were randomly divided into 5 groups, control (C), dexamethasone (Dex), water extract of P. vulgaris (PE 35 or 70 mg), and PE (70 mg) + mifepristone (PEM). After a 3-week treatment, acetic acid-induced writhing and hot plate tests confirmed the peripheral and central analgesic effects, respectively. Plasma GCs and BDNF were significantly increased. Coincidently, plasma pro-inflammatory cytokines, including IL1β, IL6, and IL10, were decreased by PE treatment, which were blocked by the application of mifepristone ( P < 0.5). Western blots confirmed GC receptor (GR) translocation, and decreased cyclooxygenase 2 in the lumber spine by PE treatment. Food intake was impeded after a 4-week PE treatment, but the ratio of bodyweight gain to food intake was increased in a time-dependent manner. An intraperitoneal glucose tolerance test disclosed that PE treatment impaired glucose disposal in mice. Quantitative polymerase chain reaction (PCR) showed that hepatic GC-responsive genes such as GC-induced leucine zipper protein and glucose-6-phosphatase catalytic subunit 1 were up-regulated, and hypothalamic neuropeptide Y and agouti-related protein expressions were decreased by PE treatment. Hypothalamic BDNF was up-regulated, whereas hepatic BDNF was down-regulated. The regulation of these genes by PE was reversed by mifepristone administration. In conclusion, PE treatment plays analgesic and glucose regulation roles simultaneously through GC-induced signaling pathways, and P. vulgaris may provide a natural ligand of GR for the treatment of inflammation with glucose dysregulation.
An Exploratory Study Testing Environmental Wayfinding Aids as an Intervention for Children With Autism
Authors: Irish Julie E. N.
Published: July 2022

Purpose:

This exploratory mixed methods experiment aimed to determine whether the application of wayfinding aids (colored doors, shapes on the floor, and signage) as an intervention could help children with autism spectrum disorder (ASD) find their way to a destination to promote independence.

Background:

Several individuals with ASD have described the difficulties they experienced finding their way in the environment. This is especially relevant to complex environments like healthcare.

Methods:

Participants with ASD aged 8–11 ( n = 9) were randomly assigned to control or treatment groups. The test location was an empty school corridor unfamiliar to participants. Each participant was shown the way to a destination using a script pointing out existing cues (control group) or applied wayfinding aids (treatment group). Participants were taken back to the start and then asked to lead the way to the destination. Afterward, they were interviewed about their experience. Data collection included observation, behavioral mapping, and video recording.

Results:

The variable of wayfinding scripts helped all participants find their way to the destination, but those in the treatment group found their way directly compared to 75% of the control group. Wayfinding aids made the environment more memorable to those in the treatment group. Some children were distracted by environmental stimuli, and some noticed surprising elements that helped them wayfind.

Conclusions:

Study results suggest that wayfinding instruction could be used as an intervention in environments with and without the application of wayfinding aids. This needs further testing in other environments. Issues included recruitment and random assignment.
Changing Roles of the State School Nurse Consultants: How the Pandemic Has Accentuated Their Value and Visibility
Authors: Pennington Barbara
Published: July 2022

State School Nurse Consultants (SSNCs) played a pivotal role in navigating school health during the COVID-19 pandemic. Schools faced unprecedented challenges in which many school administrators found themselves having to make strategic decisions on school health for the first time in their careers. The work of SSNCs has been recognized and appreciated in an unprecedented way, as they became key gatekeepers in school health, forming new partnerships with State Departments of Health and Education stakeholders; supporting school nursing practice, school nurses’ mental health, and pandemic fatigue; providing resources; and organizing many state-wide virtual trainings. SSNCs were strategic in developing state school health policy and providing funding support, increasing school nurse positions in their states. As their roles have changed, SSNCs will continue to be intentional in the promotion of health and disease prevention throughout the years to come.
Multimodal linear endobronchial ultrasound guided mediastinal lymph node biopsy in the diagnosis of isolated mediastinal lymphadenopathy

Isolated mediastinal lymphadenopathy represents a common diagnostic dilemma whereby morphological analysis of tissue specimens are frequently needed to ascertain the diagnosis. Cryobiopsy by linear endobronchial ultrasound (EBUS) guidance had recently been described in literature. We described a multimodality biopsy approach of a case of isolated tuberculous mediastinal lymphadenitis in which we employed the 22-gauge transbronchial aspiration needle, mini-forceps and a flexible cryoprobe sequentially. We aim to highlight the novel technique of linear EBUS guided cryobiopsy in acquiring superior histological specimen from mediastinal lymphadenopathy for diagnosis purposes. We also compared the histopathological quality of the specimens acquired from these three different biopsy modalities.
Three Popes: Lessons in Leadership—The Powerful Learnings of Predecessors in Developing One’s Leadership Style and Approach
Authors: Christian Valerie Labun , Trefry Mary Garlington
Published: July 2022

As educators, we seek engaging ways to demonstrate how crucial leadership is to advancing organizational success. This exercise uniquely emphasizes how much leaders may learn from their predecessors in the same role. Participants explore leadership by researching two former Bishops of Rome—John Paul II and Benedict XVI—and the incumbent pontiff, Francis. Participants investigate the personal traits, biographies, and accomplishments of each pope to understand each leader’s style and effectiveness and make recommendations to Pope Francis using this situational data of his predecessors. In doing so, the exercise creates a perspective for how participants might enhance their own leadership skills within their own professional organizations. Variations for other organizational contexts where leadership is essential are included as well as variations for online delivery modes.
