Published: March 2022

Background:

Labral augmentation has emerged as an essential procedure to address a deficient or irreparable labrum while preserving native labral tissue and restoring the hip suction seal mechanism.

Purpose:

To evaluate midterm outcomes of arthroscopic hip labral augmentation for labral insufficiency after previous hip arthroscopy.

Study Design:

Case series; Level of evidence, 4.

Methods:

Patients were identified from a prospectively collected database who underwent arthroscopic hip labral augmentation between January 2011 and January 2017 with a minimum 3-year follow-up. Pre- and postoperative patient-reported outcome scores were compared and included the 12-Item Short Form Health Survey physical and mental component summaries, Western Ontario and McMaster Universities Osteoarthritis Index, modified Harris Hip Score (mHHS), and Hip Outcome Score (HOS) (Activities of Daily Living [ADL] and Sport). Postoperative Tegner Activity Scale and patient satisfaction (1-10) scores were also evaluated. The minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) between the preoperative and minimum 3-year follow-up scores were calculated.

Results:

A total of 88 patients (39 men, 49 women) underwent revision hip arthroscopy with labral augmentation. The average age was 32.8 ± 11 years. Of these, 77 patients (88%) were available for the minimum 3-year follow-up. The survivorship (absence of conversion to total hip arthroplasty) at 3 years and 5 years was 93% at both time points, with a mean survival time of 8.5 years (95% CI, 8.0-8.9). Eleven patients (14%) required revision arthroscopic surgery for continued pain. Revisions occurred at a mean of 2.6 ± 1.4 years after augmentation. The mean follow-up was 5.2 ± 1.2 years (range, 3-9 years). For patients not requiring subsequent surgery (n = 61), all patient-reported outcome measures significantly improved, which included a 20-point increase in HOS-ADL (MCID, 82%; PASS, 72%) and mHHS (MCID, 78%; PASS, 70%). The median postoperative Tegner score was 4 (range, 1-10). The median postoperative patient satisfaction score was 9 out of 10 (range, 1-10).

Conclusion:

Arthroscopic hip labral augmentation is a successful treatment option for patients with labral insufficiency after previous hip arthroscopy, demonstrating improved patient-reported outcomes and survivorship of 93% at 3 years and 5 years. This technique provides a valuable labral preservation option when addressing hip labral pathology when viable native labral tissue remains.
Students’ Perceptions of a Simulated Store Planning Project Set in a Brick and Mortar Retail Research Lab
Authors: Smith-Glaviana Dina , Martinez Briana
Published: March 2022

Student perceptions of a simulated store planning project set in a brick and mortar retail research lab were examined using the Concrete, Active, Primary-Abstract, Passive, Secondary Learning Potency Scales for Real and Simulated Situations by Bergsteiner and Avery (2014) as a framework. Quantitative seven-point Likert-type survey data (N = 30) and qualitative student reflection paper data (N = 27) were simultaneously collected and analyzed using SPSS and NVivo Qualitative Coding software. Students perceived the project’s environment and most of the activities performed within it as realistic or having a real-world connection, except for the large number of individuals involved in store planning, which led to an implication for designing simulated projects: To be concrete, simulated learning activities must have three specific tangible elements: a realistic environment (mock retail store), realistic activities (folding, hanging, and displaying merchandise), and realistic outcomes/consequences related to activities performed (increased or decreased foot traffic among visitors).

Published: March 2022

Objectives

Using data from a large random sample of U.S. older adults ( N = 7982), the effect of loneliness and social isolation on all-cause mortality was examined considering their separate and combined effects.

Methods

The UCLA-3 Loneliness Scale and the Social Network Index (SNI) were used to define loneliness and social isolation. Cox proportional hazards regression models were performed.

Results

Among study participants, there were 548 deaths. In separate, adjusted models, loneliness (severe and moderate) and social isolation (limited and moderate social network) were both associated with all-cause mortality. When modeled together, social isolation (limited and moderate social network) along with severe loneliness remained significantly associated with mortality.

Discussion

Results demonstrate that both loneliness and social isolation contribute to greater risk of mortality within our population of older adults. As the COVID-19 pandemic continues, loneliness and social isolation should be targeted safely in efforts to reduce mortality risk among older adults.
Investigation of over-bending defect in the cold roll forming of U-channel section using experimental and numerical methods

Published: March 2022

In spite of product quality increase in the cold roll forming process by previous practical researches for defects prevention, there are some ill-considered defects such as over-bending, which diminished the product quality in the open section products of this process. This defect which happens by superfluous bending of sheet in the forming stand not only lead to defective products, but also trigger other defects such as edge wrinkling. Since in an elaborate process such as cold roll forming, forming parameters play an active role in defect prevention, the effect of some important parameters is investigated on the over-bending defect and product bending angle by doing 68 experimental tests and numerical simulations in the present study. The list of parameters which are investigated includes bend angle increment, flange width, strip thickness, radius of bend, strength of the materials, and inter-distance between successive stands. In addition, the reason behind the effect of each parameter on the accuracy of the bending angle is laid out. Results show that over-bending defect can be compensated or even eliminated by decreasing the bending angle in each stand, a technique called bending angle increment. Increasing the number of forming stands from two to five causes the over-bending to decrease from 6° to 0°. With bending angle increment being the most impactful factor, bending radius, flange width, and strip thickness have a decreasing impact on over-bending. This study also brings forward a reverse relationship between the strength of the material and the intensity of over-bending. The inter-distance between successive stands was found to have the least effect on over-bending. Results highlight the importance of pre-form rolls at the beginning of the roll forming line. Without the usage of pre-form rolls, the folding of strips on a 60° angle, cannot be done in one stand.

Published: March 2022

Continuous drive friction welding (CDFW) is an economical and productive method for joining similar metals. In this study, 45 # steel was joined via CDFW, and the material heat distribution, flow behaviour, flash formation and fracture mode were investigated via experiments and simulations. The bar was divided into three zones in the direction of radius (R), the R zone near the axis, the edge zone at the edge of the R and the 0.5 R zone between the R zone and edge zone. The maximum flow velocity and temperature of the joint first appeared in the 0.5 R zone, and as the friction continued, the maximum temperature moved to the edge zone, followed by flash. When the friction time was 9 s, the maximum tensile strength was 674 MPa, the fracture mode was the coexistence of ductile and brittle and the fracture location had an obvious boundary. Ductile fracture occurred in the R zone, and the flash took a lot of heat, brittle fracture occurred in the 0.5 R and edge zones. The maximum microhardness of the joint is 295 HV in the weld zone, and the microhardness decreased in the partially deformed zone. When the friction time was appropriate, the heat distribution was uniform and sufficient, and the grains exhibited a significant degree of dynamic recrystallisation refinement.
Uncertain trajectory planning integrating polynomial chaos and convex programming
Authors: Tan Yiting , Jing Wuxing , Gao Changsheng
Published: March 2022

The present work explores the robust trajectory optimization scheme considering both the initial state disturbance and multiple constraints. An uncertain multi-constraint optimization model has been first established. Due to the existence of the stochastic disturbance, standard numerical trajectory planning algorithms cannot be directly applied to address the considered issue. Hence, based on the intrusive polynomial chaos expansion, we present a deterministic quantification for the stochastic state and constraints, so that the transformed optimization model becomes solvable for standard numerical optimization methods. To obtain the enhanced computational performance, an hp pseudo-spectral sequential convex programming procedure combined with a penalty function and backtracking search is proposed. This is achieved by discretizing and convexifying the nonlinear dynamics/constraints using hp quadrature collocation and successive linearization, respectively, and by adjusting the confidence region manually in the iteration. The simulation of a three-dimensional interception with the specific impact angle is conducted to verify the effectiveness. The simulation results show that the initial solutions are insensitive to the convex optimization, and the control commands generated by the proposed algorithm are effective against the initial state disturbance.
Strength of Belief Guides Information Foraging
Authors: Illingworth David A. , Thomas Rick P.
Published: March 2022

Theories of how people value and search for information share the assumption that beliefs give rise to the perceived value of information. However, few studies have directly addressed the pre-search processes that influence information-foraging behavior. This experiment examined the influence of pre-search belief updating on the perceived value of information sources. A sample of college students completed a hypothesis-testing, medical-diagnosis task. The experiment used medical tests with equal objective informative value before unveiling a presenting symptom intended to alter the strength of belief in different disease hypotheses. The observed patterns of test selection suggest that changes in beliefs about disease hypotheses result in systematic and predictable changes in test preference—a notion we refer to as the principle of hypothesis-guided search. We also present a simulation of how pre-search processes (e.g., hypothesis generation and working memory capacity) and task variables (e.g., time pressure) influence subsequent information search.
Unequal but balanced: Highly educated mothers’ perceptions of work–life balance during the COVID-19 lockdown in Finland and the Netherlands

Published: March 2022

One year after the European work–life balance directive, which recognises the need for work–family policy support, measures to slow the spread of the COVID-19 pandemic began shaping parents’ work–life balance in significant ways. Academically, we are challenged to explore whether existing theoretical frameworks hold in this new environment with combined old and new policy frameworks. We are also challenged to understand the nuanced ways in which the first lockdown affects the combination of paid work and care. We address both of these issues, providing a cross-sectional comparative analysis of highly educated mothers’ perceptions of work–life balance during the COVID-19 pandemic in Finland and the Netherlands. Our findings show that highly educated Finnish mothers have more difficulty combining work and care during the first lockdown than Dutch mothers. The absence of state-provided care during the lockdown creates greater difficulty for full-time working Finnish mothers in a dual-earner/state-carer system than an absence of such care in the Dutch one-and-a-half earner system, where most mothers work part time. Further analyses suggest variation in part-time and (nearly) full-time hours mitigates the work–life balance experiences of highly educated Dutch mothers. Additional factors explaining cross-country variation or similarities include the presence of young children and the presence of a partner. We discuss these findings in light of current theoretical frameworks and highlight avenues for future research.
Effects of electroacupuncture on DNA methylation of the TREM2 gene in senescence-accelerated mouse prone 8 mice
Authors: Jiang Jing , Liu Hao , Wang Zidong , Tian Huiling , Wang Shun , Yang Jiayi , Li Zhigang
Published: March 2022

Objective:

To explore the mechanism by which electroacupuncture (EA) upregulates triggering receptor expressed on myeloid cells 2 (TREM2) protein in the hippocampus of Alzheimer’s disease (AD) model animals from the perspective of TREM2 DNA methylation.

Methods:

In total, 24 eight-month-old senescence-accelerated mouse prone 8 (SAMP8) mice were divided into an (untreated) AD group (n = 8), donepezil group (receiving donepezil treatment, n = 8) or EA group (receiving an EA intervention, n = 8). A healthy control group comprising 8-month-old senescence-accelerated mouse resistant 1 (SAMR1) mice (n = 8) was also included. Western blotting, bisulfite sequencing, and oxidative bisulfite sequencing were applied to test the relative expression of TREM2 protein and the methylation levels of the TREM2 gene.

Results:

EA significantly upregulated the relative expression of TREM2 protein (p < 0.01), downregulated the 5-methylcytosine level (p < 0.01) and upregulated the 5-hydroxymethylcytosine level (p < 0.05) in the hippocampus.

Conclusion:

Downregulation of 5-methylcytosine levels and upregulation of 5-hydroxymethylcytosine levels in the TREM2 gene might be the mechanism by which EA promotes the expression of TREM2 protein.

Authors: Cai Wa , Ma Wen , Li Yi-Jing , Wang Guan-Tao , Yang Hong , Shen Wei-Dong
Published: March 2022

Objective:

The objective of this study is to evaluate the efficacy and safety of electroacupuncture (EA) treatment for post-stroke depression (PSD).

Methods:

This study was a single-center, single-blinded, parallel-arm randomized controlled trial. In total, 65 patients with PSD were randomly allocated into EA and sham EA groups. Treatment was administered at GV20, Sishencong, SP6, LR3 and BL18 in both groups. The EA group received EA treatment, while the sham EA group received sham EA treatment using the Park device. Treatment was given three times a week for 4 weeks. The primary outcome was the Hamilton Rating Scale for Depression (HRSD). Secondary outcomes included the Zung Self-Rating Depression Scale (SDS), National Institutes of Health Stroke Scale (NIHSS), Barthel Daily Living Index (BI) and depression scale of traditional Chinese medicine (TCM). Primary and secondary outcomes were assessed at baseline, week 2 after treatment, week 4 after treatment and week 8 of follow-up. Safety assessment was conducted at each visit for 4 weeks of treatment.

Results:

Significant differences in HRSD, SDS, NIHSS, BI and TCM scale scores were found in the EA group before and after acupuncture treatment (all p < 0.001). Compared with the sham EA group, HRSD scores improved significantly in the EA group at the end of week 2 (F = 31.33, p < 0.001), week 4 (F = 35.58, p < 0.001) and week 8 after treatment onset (F = 25.03, p < 0.001). Similarly, significant improvements were observed in SDS, NIHSS and BI scores. Two participants in the EA group suffered a local hematoma, while no adverse events were reported in the sham EA group.

Conclusion:

EA appears to be an efficacious and safe treatment for PSD. According to our results, EA may alleviate depressive symptoms, and improve neurological function and capabilities with respect to activities of daily living (ADLs).

Dividend policy from the perspective of social system theory
Authors: Wechta Przemysław
Published: March 2022

The aim of the article is to analyse the functions that dividends perform in contractual relationships between public companies’ executives and shareholders. The author analyses the income function of dividend, but also considers its sociological aspects. Talcott Parsons' social system theory is the main point of reference, especially, the concept of contract institution. The article justifies the thesis on the relevance of dividends in shaping the equilibrium of power, information policy and the composition of shareholders in a joint-stock company. Dividend policy has a great regulatory potential, which is important in the face of various crises occurring in contemporary capitalism.
Does Contact with the Justice System Influence Situational Action Theory's Causes of Crime? A Study of English and German Juveniles
Authors: Kaiser Florian
Published: March 2022

To explore why system contact often has no crime-preventative effect, the current study examined the effects of juvenile justice contact on Situational Action Theory's (SAT) causes of crime, including personal morals, deviant peer associations, and detection risk perceptions. The analysis is based on a sample of English (Peterborough Adolescent and Young Adult Development Study) and German (Crime in the modern City study) juveniles. Propensity score matching was applied to estimate whether the lenient system contacts influenced the causes of crime in the year after the contact. The treatment effect estimates are mostly insignificant and relatively small. The few significant estimates in the English sample suggest that official contact slightly increased deviant peer associations and decreased feelings of moral guilt. Overall, the findings suggest that system contact may often have no crime-preventative effect as it does not (Germany), or only slightly (England) affect SAT's causes of crime. Previous studies, primarily based on the U.S. data, often reported more substantial effects that mostly operated in a crime-amplifying direction. It is speculated whether the less substantial impact in the current study can be attributed to the overall more lenient, diversion-oriented handling of the examined English and German offenders.
Calvin and Przywara's Analogia Entis: A New Start for an Old Debate
Authors: Komline Han-luen Kantzer
Published: March 2022

This paper brings the thought of John Calvin into dialogue with Erich Przywara's Analogia Entis in order to reboot the Reformed-Catholic dialogue on the analogy of being, which Karl Barth has tended to dominate. The paper begins by distilling from Analogia Entis, and explicating, nine key principles that express Przywara's understanding of the analogy of being (Part I). It then turns to the relationship between God and creation expressed in Calvin's Institutes 1.1–5, demonstrating that in these crucial opening chapters Calvin explicitly affirms his own version of each of these nine principles save one, which he explicitly endorses elsewhere in the Institutes (Part II). Based on this analysis, the paper proposes that the relationship between Calvin and Przywara ought best to be viewed as one of dissimilarity amid greater similarity and that Calvin be retrieved as a fruitful resource for Reformed-Catholic détente on the issue of ontology.
Uneven domestic tourism demand in times of pandemic
Authors: Falk Martin , Hagsten Eva , Lin Xiang
Published: March 2022

This study investigates the short-run impact of the COVID-19 pandemic on the number of domestic overnight stays at the regional level in the summer season 2020. Official data for 65 regions in four countries are used for the analysis (Austria, the Czech Republic, Germany and Switzerland). Dynamic panel data models are employed to estimate a tourism demand equation (real GDP and price fluctuations) augmented by average temperatures. Estimation results reveal that domestic overnight stays evolve unevenly in the first summer after the outbreak of the COVID-19 pandemic. The short-run effects show that the number of domestic overnight stays in densely populated regions decreases by 27% in July as well as in August 2020, in comparison with the same months in previous years, ceteris paribus. To the contrary, there is a surge of 27 and 10%, respectively, for sparsely populated areas in the same months.

Imagining the social future of drones
Authors: Serafinelli Elisa
Published: March 2022

Despite the opportunities afforded by the growing use of drones, their civilian use causes concern as they can capture, share and store images of events and people following a set of norms still in development. The main challenges risen by drone usage relates mainly to existing gaps in regulation and the difficulty to enforce approved guidelines. Further changes and implementation of drone legislation will broadly affect current applications and future opportunities shaping the way civilians will be allowed to use drones. This article explores these issues qualitatively, analysing (i) civilian users’ and developers’ views on drone usage, (ii) their knowledge of relevant regulations and (iii) how they imagine its use should be regulated. In its conclusion, this article discusses the general concern of potential privacy infringements and the importance to take into account civilians’ thoughts in further implementation of drone law in order to protect recreational practices.
Measurements of the Periocular Facial Area with Web-Based Software
Authors: Gonzalez Francisco , Castro Adrian F , Schneider Klaus , Lozano Maria
Published: March 2022

We developed a simple Web-based program to make measurements on displayed photographs between several ocular and periocular landmarks. The measurements were: (1) vertical distance between the margin of the upper and lower eyelids (palpebral aperture), (2) distance between the lower eyelid margin and the inferior corneal margin (palpebro-limbar distance); (3) interpupillary distance; (4) ocular proptosis. We measured the distances using the Web program and compared them with manual measurements on the subject's face. The measurements involved 102 eyes of 51 patients with a variety of ophthalmic conditions. There was good agreement between manual and computer measurements. For example, for manual measurements in 49 patients, we obtained interpupillary distances ranging from 45 to 69 mm (mean 61, SD 6), whereas for computer measurements we found values ranging from 42 to 49 mm (mean 59, SD 6). The mean of the differences between manual and computer measurements was -2.0 mm (SD 4.3) and the 95% limits of agreement were -6.5 to 10.5 mm. Thus, computer measurements tended to give a higher reading by between 0.8 and 3.2 mm (95% confidence interval for the difference). Web-based software may be used to perform measurements on two-dimensional pictures and the technique appears to be suitable for telemedical purposes.

Authors: Jafarigohar Manoochehr , Divsar Hoda , Etemad Parisa
Published: March 2022

This cross-sectional study aimed to explore the nature and the patterns of lexical growth in content and language integrated learning (CLIL) and non-CLIL learners across three successive academic years. To pursue the purpose of the study a total of 110 female students of six classes in 3rd, 4th, and 5th grades in both bilingual and monolingual schools in Tehran, Iran, were selected. The experimental group included 50 students, while the control group included 60 students. Receptive and productive vocabulary sizes of three grades from both environments were compared using the Vocabulary Levels Test (VLT) and the Productive Vocabulary Levels Test (PVLT). The results indicated that learners’ receptive and productive vocabulary sizes in both CLIL and non-CLIL groups are below 1,000 words, according to the results of the 2k VLT and 2k PVLT tests. In addition, both CLIL and non-CLIL groups showed a gradual increase in their receptive and productive vocabulary growth from third grade to fourth and fifth grades. Finally, across all three grades, the CLIL group showed a higher increase in their receptive and productive vocabulary growth than the non-CLIL group. The results of the study have implications for bilingual schools, language institutes, and language teachers and learners.
A culturally grounded autism parent training program with Black parents
Authors: Kaiser Kim , Villalobos Michele E , Locke Jill , Iruka Iheoma U , Proctor Camille , Boyd Brian
Published: March 2022

Parent training (i.e. group-based supports and psychoeducation aimed at parent as primary agent of change) in Autism Spectrum Disorders (autism) is well-documented as an Evidence-Based Intervention designed to increase advocacy, knowledge, and empowerment. While research on Parent Training acknowledges the cultural limitations, the field lacks culturally grounded models. Furthermore, barriers in diagnosis, service acquisition, and inclusion of under-represented populations including Black families have been established; however, research programs have traditionally failed to include these families. This study aims to provide a first toward addressing the lack of inclusion. We describe the practice-based implementation of a culturally concordant Parent Training program (Spectrum of Care) developed by a community organization (the Color of Autism) as well as feedback from parents after the implementation process. The findings indicate that culturally grounded strategies could promote engagement and empowerment of Black families. There, however, is still a need for research that attends to parental mistrust and examines culturally grounded strategies more closely.

Lay abstract

Parent training programs have been well-studied in Autism Spectrum Disorders and shown to increase a parent’s feeling of empowerment, advocacy skills, and treatment enrollment for their child. The majority of parent training interventions have been developed without considering the unique needs of under-represented communities, such as the Black community. Black children with autism are not only misdiagnosed or not diagnosed at all, but are not accessing services equally compared to their White peers. There is an urgent need for culturally adapted interventions in order to decrease the disparity gap. The Color of Autism Foundation developed and ran a parent training program for Black parents of children with autism. The program was grounded in two key features: (1) creating a circle of support for parents to connect and heal from ongoing and historical racial trauma and (2) using parents of Black children with autism as the main facilitators. We believe this increased parent’s ability to engage in the educational aspects of the training. Overall, parents reported high levels of satisfaction with the training were highly engaged (attended an average of five of six sessions) and reported high levels of empowerment. Parents also reported continued mistrust in the medical and research community and a need for more Black providers. Further work should examine the relationship of the parent and provider in autism treatment and study the impact of circles of healing for Black families.

Published: March 2022

Transition services for young people with long-term conditions often fall short. This qualitative study explored perspectives on service features that enable effective transition in epilepsy and juvenile idiopathic arthritis. Patients, parents, clinicians and service commissioners took part in semi-structured interviews ( n = 18). Thematic analysis was used to identify key features, barriers and facilitators of effective transition across participant groups. Analysis led to the development of nine sub-themes which mapped to overarching domains of communication, capability, continuity and capacity. Findings include the need for age appropriate communication, the link between parental dependence, self-care and patient knowledge, the value of service integration for continuity and the impact of capacity on flexible and age appropriate transition services.
Aimage's entrepreneurial value creation and crowdfunding: Entrepreneurship in times of crisis
Authors: Nespoli Chiara , Kozan Asli , Scuotto Veronica , Giudice Manlio Del
Published: March 2022

The increasing amount of investment through crowdfunding platforms despite the recent global economic downturn brought about by the COVID-19 pandemic has nurtured the interest in how this form of investment can generate non-monetary value for a company. Through the lens of the entrepreneurial value creation (EVC) theory, the present case study demonstrates the development of two key stages of a new venture: (1) formulation and (2) monetization. The study employs a case study approach based on a high-tech company in Italy, namely Aimage. The case demonstrates how Aimage improves entrepreneurial competences by the acquisition of dynamic capabilities through means of a crowdfunding campaign. It shows how to gain not just monetary but also non-monetary benefits, mainly in the form of entrepreneurial knowledge. Moreover, the case of Aimage confirms that crowdfunding brings added value to an entrepreneurial venture in its monetization stage—even when capital is not needed for survival but for overcoming time of crisis—by enhancing its dynamic capabilities and helping to transform entrepreneurial competence into entrepreneurial reward.
A 40 year (contextualized) social work journey
Authors: Schmid Jeanette
Published: March 2022

Employing critical autoethnography, this article conveys how over my four decades of social work, I have come to adopt a contextualized social work stance and identifies what emerge as four key areas of contextualized social work. These include attention to race, ethnicity and culture as experienced in the local environment, the local articulation of social conditions and appropriate social work responses, the activation of local knowledge generation and curation, and finally, addressing and resisting expert power. Such theorization of contextualized social work augments previous work that positions contextualized social work as countering dominant conceptualizations of social work and instead centering on a critical interrogation of the local, foregrounding local understandings of social conditions, and privileging local/(i)Indigenous knowledge production and ways of doing and being. This critical understanding of context unsettles dominant notions of context by focusing on power relationships. I hope that my story will add to the growing discussion regarding alternative modes of practice and education that counter dominant Westernized individualized social work perspectives and promote decolonized approaches.
A practical method for field measurement of mean room surface exitance
Authors: Zhang P , Li M , Huang Y , Dai Q
Published: March 2022

Cuttle has proposed to use mean room surface exitance (MRSE) as a measure of spatial brightness for interior lighting design. One problem hindering the adoption of MRSE is the lack of a practical field-measurement method with verified accuracy. Although Cuttle suggested that MRSE can be estimated by measuring the illuminance caused by indirect light from a position that takes up an overall view of the room, no evidence was provided and that approach was later proved to be inaccurate. This paper presents a newly developed approach for measuring MRSE in a conventional cuboid space, simply by placing an illuminance meter at specific locations, recording the illuminance values caused by indirect light and calculating the weighted average of those values. The weighting parameters can be determined based on the geometry of the space. Furthermore, the rationality of such an MRSE-measurement method is provided, and its accuracy is verified by using Radiance lighting simulation, which suggests an error of less than 10%. Our proposed method shows that measuring MRSE in the field is feasible.
Domestic Violence in Cross-Border Marriages: A Systematic Review
Authors: Md Said Muhamad Helmi Bin , Emmanuel Kaka Grace
Published: March 2022

Cross-border marriages have been found to be associated with domestic violence due to the migration experiences of the couples concerned and the stress experienced before, during, and after migration, despite local and international legislation on domestic violence. A systematic review using the PRISMA Statement was conducted to examine the relationship between domestic violence and cross-border marriages among cross-border wives from Asian countries. Six databases—Taylor & Francis Online, Wiley Online, Scopus, Web of Science, Sage Journals, and Springer Online library, were used in the research which found 179 articles for eligibility and 58 articles were finally used in the review. To be included, studies must have addressed domestic violence and cross-border marriage among Asians, report qualitative, quantitative, or mixed methods, addressed the RQs, been published in polished English between 2010 and 2020 and published in a reputable journal with high impact factor. The systematic review found that immigration status, citizenship, culture, language barrier, diversity/intersectionality, age, and economic dependence are the risk factors for domestic violence, which leads effects such as divorce or separation, racism, loneliness, loss of identity & inheritance, stigma, abandonment, and discrimination. Yet these cross-border wives resorted to NGOs, social & religious groups, and traditional beliefs as coping strategies. The review suggests that legislations on domestic violence should be amended to include a definition of the rights of immigrant women, and the plight of cross-border wives, which should be protected. It is also imperative to propose favorable laws and policies regarding immigration status and citizenship for these cross-border couples.
An improved algorithm of segmented orthogonal matching pursuit based on wireless sensor networks
Authors: Lu Xinmiao , Su Yanwen , Wu Qiong , Wei Yuhan , Wang Jiaxu
Published: March 2022

Aiming at the problems of low data reconstruction accuracy in wireless sensor networks and users unable to receive accurate original signals, improvements are made on the basis of the stagewise orthogonal matching pursuit algorithm, combined with sparseness adaptation and the pre-selection strategy, which proposes a sparsity adaptive pre-selected stagewise orthogonal matching pursuit algorithm. In the framework of the stagewise orthogonal matching pursuit algorithm, the algorithm in this article uses a combination of a fixed-value strategy and a threshold strategy to screen the candidate atom sets in two rounds to improve the accuracy of atom selection, and then according to the sparsity adaptive principle, the sparse approximation and accurate signal reconstruction are realized by the variable step size method. The simulation results show that the algorithm proposed in this article is compared with the orthogonal matching pursuit algorithm, regularized orthogonal matching pursuit algorithm, and stagewise orthogonal matching pursuit algorithm. When the sparsity is 35 < K < 45, regardless of the size of the perception matrix and the length of the signal, M = 128, N = 256 or M = 128, N = 512 are improved, and the reconstruction time is when the sparsity is 10, the fastest time between 25 and 25, that is, less than 4.5 s. It can be seen that the sparsity adaptive pre-selected stagewise orthogonal matching pursuit algorithm has better adaptive characteristics to the sparsity of the signal, which is beneficial for users to receive more accurate original signals.
Beyond NAGPRA/Not NAGPRA
Authors: Wheeler Ryan , Arsenault Jaime , Taylor Marla
Published: March 2022

Institutions have been slow to respond to calls from Indigenous nations, organizations, and scholars to require free, prior, and informed consent before authorizing use of their cultural heritage materials in publications, exhibition, and research. In the United States, the Native American Graves Protection and Repatriation Act of 1990 fundamentally changed the relationship between museums, archaeologists, and Indigenous nations, requiring institutions to inventory their collections and consult with descendant communities on repatriation of specific Indigenous collections. In response, institutions and their personnel have come to view Indigenous collections as those subject to NAGPRA and those that are not—NAGPRA/Not NAGPRA. Many Indigenous nations, however, do not accept this demarcation, resulting in continued frustration and trauma for those descendant communities. This case study follows the evolving relationship between the White Earth Band of the Minnesota Chippewa Tribe and the Robert S. Peabody Institute of Archaeology. Beginning with repatriation, the relationship has expanded to consider how the museum and Indigenous nation can collaborate on the care and curation of cultural heritage materials that remain at the Peabody Institute. Most recently, White Earth and the Peabody have executed an MOU that governs how the museum will handle new acquisitions, found-in-collections materials, and donor offers. The relationship with the White Earth also has influenced how the Peabody Institute approaches its holdings of Indigenous cultural heritage materials more broadly, blurring the line between NAGPRA and Not NAGPRA collections. The Peabody Institute is working to revise its collections policy to require free, prior, and informed consent prior to use of Indigenous cultural heritage materials in publications, exhibitions, and research.
Moving Toward Land-Based Sound Archiving and Composition: Reflecting on Field Research From the Project Sonic Coordinates: Decolonizing Through Land-Based Composition
Authors: Dénommé-Welch Spy , Becker Jean , Garcia Vega Cecilia
Published: March 2022

This paper examines the intersection of environmental sound recording, sound collection, and archiving by drawing on Land-based approaches, Indigenous epistemologies, and methodologies. In particular, this paper considers some of the implications for immersive sound-based fieldwork informed by site-specific listening methods, embodied learning and forms of reflexivity that are rooted in Indigenous concepts of relationality (kinship). Specifically, this paper revolves around an initial field research trip from our project Sonic Coordinates: Decolonizing through Land-based music composition (supported by the New Frontiers Research Fund) which took place in the region of Timiskaming (Northern Ontario, Canada) during the fall of 2019. Consequently, our paper examines what was learned through this process, and how critical listening and recording/collection of environmental sounds can be used to inform Indigenous sound/music composition and aural forms of storying. This paper ultimately explores the ephemeral concepts of sound materiality and how aural archiving and documentation (through digitizing and digital platforms) is used to preserve and engage historical memory, cultural knowledge and shifts toward the development of sonic art and communication that is informed by site-specific research practice.
Toward a Language of Possibility in Curation and Consultation Practices

Language, especially categorization and description through language, is a frequent barrier to collaboration when it comes to collections taken from Native American and Indigenous communities. This impacts collections care within institutions and for the Native people whose relatives and objects are held in those institutions. Drawing on our experiences as NAGPRA and repatriation practitioners, we offer examples of adopting a “language of possibility.” Current legal and non-Indigenous institutional nomenclature often assumes that the categories used to describe Indigenous collections are “common sense,” and adjustments to that language are often only made after direct intervention from Native American and Indigenous communities. These terms and norms of discourse originate in white, EuroAmerican ideologies of science and scientific classification, and those ideologies are inseparable from their concomitant religious and linguistic systems. Shifting to language that recognizes animacy, or allows for the possibility of it, has the potential to undo this harm before, during, and after consultation and collaboration with Native Nations and Indigenous stakeholders. Language is a site of intervention into non-Indigenous assumptions and practices that not only create barriers to consultation and repatriation, but also directly impact collections care.

This essay builds on the emerging (museum) decolonizing perspectives to (i) explore the biographical details and modes of curation and classification to which “ethnographic”1 objects collected during the colonial era have been exposed; to (ii) foreground the complexities of inherited colonial museum processes embedded in African urban contexts; and, to (iii) consider alternative modes of engagement with ethnographic objects and local Indigenous communities to challenge the embedded regimes of care and the marginalization rendered to Indigenous epistemologies. One of the biggest questions facing museums in the world today is how to deal with the hordes of objects collected from various Indigenous communities and placed in museums far away from the communities who made and used them. Using the case of an “ethnographic” collection in a former colonial museum, we call for a paradigm shift in museum practices, and challenge the present state of affairs of museum curatorship. We then briefly suggest possible ways in which such museums can confront their imperial histories and unsettle their inherited regimes of care and representation. We call for museums to enter into conversations with communities, listening to them and effecting curatorial activities that re-center local ways of knowing, while embracing the complexities associated with such engagements.
Fluorescence Imaging in Colorectal Surgery: An Updated Review and Future Trends

Published: March 2022

Fluorescence imaging in colorectal surgery is considered a novel predominantly intraoperative method of ensuring a greater surgical success. The use of fluorescence is linked to advanced tumor visualization and projection of its lymphatics, both vessels and nodes, which results in a higher chance of achieving a total excision. Additionally, iatrogenic complications prove to be reduced using fluorescence during the surgical excision. The combination of fluorescence and artificial intelligence to better facilitate oncological surgery will soon become an established approach in operating rooms worldwide.
Rapid Ventricular Pacing Facilitates Transarterial Embolization in Vein of Galen Malformations
Authors: Jones Jesse G.A. , Kane Austin
Published: March 2022

Background: Mural type vein of Galen malformation (mVOGM) is a congenital high flow arteriovenous shunt between choroidal arteries and the prosencephalic vein of Markowski leading to heart failure and hydrovenous disorder in children. Embolizing fistulous connections can be challenging and typically requires adjunctive techniques such as induced hypotension, balloon-assisted flow control, and creation of a coil basket. These maneuvers add time, complexity, and unpredictability. Rapid ventricular pacing (RVP) has been proposed as an alternative strategy with fewer drawbacks, but has not been well studied. The approach involves catheterizing the right ventricle with a pacing catheter connected to a temporary external pacemaker. Prior to embolization, RVP is initiated to lower cardiac output. Following embolization, pacing is discontinued, and the heart returns to sinus rhythm. Methods: We performed RVP in five mVOGM patients from 4/2020 through 7/2021. Accounting for multiple procedures, RVP was utilized in ten cases and twenty-six pedicles. Results: Ventricular capture was achieved in all instances and was well tolerated, without arrhythmia. Casting the arterial pedicle with liquid embolic immediately adjacent to, or traversing, the fistulous point was achieved in 9/10 cases. There were no procedural complications. In 1 case, creation of a coil basket in the venous pouch was required to achieve a stable arterial cast Conclusions: This report describes the largest case series utilizing RVP in mVOGM. The technique appears safe and well tolerated.

Background and Purpose

Some cervical artery dissection (CAD) can't be easily confirmed by commonly used angiography techniques in clinical practice. We aimed to compare the abilities of the vessel wall magnetic resonance imaging (MRI) techniques including simultaneous noncontrast angiography and intraplaque hemorrhage (SNAP) sequence and T1-weighted volumetric isotropic turbo spin echo acquisition (T1-w VISTA) sequence alone for evaluating CAD.

Materials and Methods

From July 2017 to October 2020, 59 patients underwent MRI examinations including SNAP and T1-w VISTA sequences for cervical artery pathologies. SNAP and T1-w VISTA images were retrospectively and independently reviewed to evaluate their diagnostic performances of CAD by using the final diagnosis as the reference standard which was established by clinical history, physical examination, and all available images. The agreement between T1-w VISTA and SNAP in the identification of the imaging features of CAD, including intramural hematoma (IMH), intimal flap, and double lumen, were compared. The IMH-wall contrasts by T1-w VISTA and SNAP were also compared.

Results

CAD was confirmed in 43 of the 59 patients. T1-w VISTA and SNAP showed the same diagnostic performance, and their consistencies with the final diagnosis were good (κ = 0.776, p < 0.001). The sensitivity and specificity in CAD diagnosis were 0.978 and 0.750 for T1-w VISTA and SNAP. The IMH, intimal flap, and double lumen observed on SNAP were also determined by T1-w VISTA (κ = 1.000, p < 0.001 for all). The SNAP sequence showed higher IMH-wall contrast than T1-w VISTA (7.34 ± 4.56 vs. 3.12 ± 1.17, p < 0.001).

Conclusions

SNAP and T1-w VISTA sequences had the same performance in CAD diagnosis, thus they were both recommended. In addition, SNAP showed better IMH-wall contrast than T1-w VISTA.
