Affective Responses to Image Color Combinations
Authors: Koenderink Jan J. , Braun Doris I. , van Doorn Andrea J.
Published: December 2021

Responses to colored patterns were collected for a group of 60 naive participants. We explicitly aimed at affective responses, rather than aesthetic judgments, so this is not ‘color harmony’ proper. Patterns were mainly spatially highly structured compositions, the color palettes reminiscent of what is found in generic ‘colorist’ art. Color combinations systematically cover mono-, di-, and trichromatic chromatic chords, whereas there was always an additional achromatic component. This sets the research apart from the bulk of the mainstream literature on ‘color harmony.’ Various ways of analysis are compared. Clustering methods reveal that the responses are highly structured through the teal–orange (cool–warm) dimension. Clustering reveals a large group of mutually concordant participants and various small, idiosyncratic groups. When the data is coarse-grained, retaining only a limited red–blue–yellow palette, the group as a whole appears quite concordant. It is evident that responses are systematic, thus the notion of a universal affective response to color combinations gains some credibility. The precise affective responses are specific because constrained by the seven categories used in the experiment. Thus, the systematic structure is perhaps to be understood as the generic result. We discuss tangencies with various traits found with ‘colorist’ art styles.
A new genus Bongotarsonemus with two new species of tarsonemid (Acari: Heterostigmata) mites discovered from the Himalayan forests of West Bengal, India
Authors: MONDAL PRIYANKAR , KARMAKAR KRISHNA
Published: December 2021

Bongotarsonemus unicornus gen. nov., sp. nov. (Tarsonemidae: Tarsoneminae) is described from adult females and males collected on leaves of Sweet Cherry, Prunus avium L. (Rosaceae). Another species, Bongotarsonemus bicornus sp. nov. is described from adult females collected on leaves of a mountain fern Arthromeris wallichiana (Spreng.) Ching (Polypodiaceae). Both species were collected from the Himalayan forests of Darjeeling district in the State of West Bengal, India. Adult females of this new genus are unusual in having a median raised section of the prodorsum which is delimited by elongated tubercles bearing setae v1 and sometimes sc2. This area is ornamented with sclerotized ridges or elevated strial thickenings; and has a single or bifurcated spear-shaped horn between bases of setae v1. The new genus also has a characteristically bipartite sejugal apodeme and seta d on tibia I often reaching beyond the claw. Adult males are characterized by seta sc2 subequal to sc1; tarsus II with baciliform seta pl'' longer than half the length of the segment, and a conspicuously enlarged solenidion on tarsus IV. Both sexes are unique in having a fish-hook shaped claw on leg I with an elongated shank and strongly curved apex, and seta l' on femur I plumose.
Defending the Traditional Polish Way of Life: The Role of Fantasies
Authors: Melito Francesco
Published: December 2021

Defending the Traditional Polish Way of Life: The Role of FantasiesThe current escalation of the cultural conflict in Poland is described as a cultural war between neo-traditionalist and liberal worldviews. Drawing on psychoanalytic political theory and Poststructuralist Discourse Theory (PDT), fantasmatic narratives are deemed as an instrument to conceal the non-necessary character of identities. Based on the direct observation of the counter-marches against LGBT parades in Kalisz, Lublin, and Kraków (2019–2020), this article shows how fantasies define the ‘authentic Polish way of life’: from the traditional family in an idyllic scenario (beatific fantasy) to the ‘LGBT virus’ (horrific fantasy), fantasies sustain a neo-traditionalist conception of Polishness and exclude antagonistic visions. Also, religious symbols are sublimated to embody the lost unity: a harmonious society without the conflict generated by the liberal value system. The fantasmatic logic analyzed in the article explains how neo-traditionalist fantasies strengthen identities and provide the necessary ideological ground to resist the emancipatory impetus of liberalism. Broniąc tradycyjnego polskiego stylu życia. Rola fantazjiAktualnie zaostrzający się konflikt kulturowy w Polsce określa się mianem wojny kulturowej między światopoglądem neotradycjonalistycznym a liberalnym. Odwołując się do psychoanalitycznej teorii politycznej i poststrukturalistycznej teorii dyskursu, autor uznaje fantazmatyczne narracje za narzędzie maskujące niekonieczny (non-necessary) charakter tożsamości. Na podstawie bezpośredniej obserwacji kontrmanifestacji organizowanych jako sprzeciw wobec marszów równości w Kaliszu, Lublinie i Krakowie (2019–2020) w artykule zaprezentowano, w jaki sposób fantazje definiują „prawdziwy polski styl życia”: poczynając od obrazu tradycyjnej rodziny w sielankowym otoczeniu (beatific fantasy), na „wirusie LGBT” (horrific fantasy) kończąc, fantazje podtrzymują neotradycjonalistyczną koncepcję polskości i wykluczają jej odmienne wizje. Z kolei symbole religijne zinstrumentalizowano tak, by ucieleśniały utraconą jedność – harmonijne społeczeństwo bez konfliktów wywoływanych przez liberalny system wartości. Fantazmatyczna logika analizowana w artykule pozwala wyjaśnić, jak neotradycjonalistyczne fantazje wzmacniają tożsamości i dostarczają niezbędnej podstawy ideologicznej, aby stawić opór emancypacyjnemu naporowi liberalizmu.
Solar Monitoring of the NEXRAD WSR-88D Network Using Operational Scan Data
Authors: Holleman Iwan , Huuskonen Asko , Taylor Brandon
Published: December 2021

Solar monitoring is a method in which solar interferences, recorded during operational scanning of a radar, are used to monitor antenna pointing, identify signal processor issues, track receiver chain stability, and check the balance between horizontal and vertical polarization receive channels. The method is used by EUMETNET to monitor more than 100 radars in 20 European countries and it has been adopted by many national weather services across the world. NEXRAD is a network of 160 similar S-band weather radars (WSR-88Ds), which makes it most suitable for assessing the capability of the solar monitoring method on a continental scale. The NEXRAD level-II data contain radial-by-radial noise power estimates. An increase in this estimate is observed when the antenna points close to the sun. Our decoding software extracts these noise power estimates for the horizontal and vertical receive channels (converted to solar flux units) and other relevant metadata, including azimuth, elevation, observation time, and radar location. Here we present results of analyzing one year of solar monitoring data generated by 142 radars from the contiguous United States. We show monitoring results, geographical maps, and statistical outcomes on antenna pointing, solar fluxes, and differential reflectivity biases. We also assess the quality of the radars by defining a figure of merit, which is calculated from the solar monitoring results. The results demonstrate that the solar method provides great benefit for routine monitoring and harmonization of national and transnational operational radar networks.
Morality, Emotions, and the Ideal Environmentalist: Toward A Conceptual Framework for Understanding Political Polarization
Authors: Kennedy Emily H. , Muzzerall Parker
Published: December 2021

Americans are politically polarized in their views on environmental protection, and scholars have identified structural and cultural drivers of this polarity. Missing from these theories is a consideration of the emotional dynamics at play in environmentally relevant interactions between liberals and conservatives. Based on analyses of in-depth interviews conducted with 63 politically and socioeconomically diverse residents of four communities in Washington State, we find evidence of important common ground across the political spectrum. Our participants voice support and respect for environmental protection and convey a shared image of an ideal environmentalist: a conscious, caring, and committed individual who seeks to reduce their personal environmental impact. We see political differences arise when our participants evaluate their own relationship with the environment against this ideal environmentalist. Liberals are more likely to align with or admire the ideal environmentalist and conservatives are more likely to challenge or denigrate the ideal. Emotions and competing claims for moral worth, we suggest, play a role in making these political differences polarizing.
Using Structural Topic Modeling to Explore the Role of Framing in Shaping the Debate on Liquefied Natural Gas Terminals in Oregon
Authors: Stelmach Greg , Boudet Hilary
Published: December 2021

The drastic increase in domestic production of natural gas due to the fracking boom prompted efforts to develop a robust infrastructure in the U.S. to export natural gas. Given environmental concerns over increased fossil fuel development, significant opposition mobilized to “keep it [fossil fuels] in the ground” by acting to prevent not only natural gas production but also its transportation via pipelines and shipping via export terminals. Our analysis focuses on the latter component, specifically examining the long history of proposed liquefied natural gas infrastructure in two coastal communities in Oregon. Members of the public engaged in the formal siting processes and mobilized both opposition and support. We examine their use of collective action frames in both comments at public hearings and letters to the editor in local newspapers ( N = 4618) over the 16 years that these proposals were under consideration, quantifying the dynamic nature of framing using computational text analysis. We find that both groups vary their use of framing over time and by venue, reacting to exogenous events (e.g., September 11th, Fukushima) and tailor their messages to the context (e.g., an in-person hearing or a letter to the editor). Opponents concentrated on potential threats, initially emphasizing local impacts like tanker and pipeline safety but eventually focusing on climate concerns. Supporters, meanwhile, stressed the economic benefits of the projects but alternated their specific framing based on venue—focusing on employment when talking to regulatory agencies and community economic benefits in letters. While this juxtaposition of economic benefits and environmental threats was a key part of public discourse, opponents also expanded their framing to questions of local sovereignty and governance, allowing a broader coalition to develop and ultimately succeeding in defeating the proposals.

Published: December 2021

Background

Solid pseudopapillary tumors (SPTs) of the pancreas arise rarely in children, are often large, and can associate intimately with splenic vessels. Splenic preservation is a fundamental consideration when resecting distal SPT. Occasionally, the main splenic vessels must be divided to resect the SPT with negative margins, but the spleen can be preserved if the short gastric vessels remain intact (ie, Warshaw procedure). The purpose of this study was to evaluate outcomes of distal pancreatectomy (DP) for SPT in children and to highlight 2 cases of splenic preservation using the Warshaw procedure.

Methods

Patients 19 years and younger who were treated at a single children’s hospital between July 2004 and January 2021 were examined. Patient characteristics were collected from the electronic medical record. A pediatric radiologist calculated SPT and pre- and post-operative (ie, non-infarcted) splenic volumes.

Results

Eleven patients received DP for SPT. Six DPs were performed open and 5 laparoscopically. The spleen was preserved in 3 open and 4 laparoscopic DPs. A laparoscopic Warshaw procedure was performed in 2 patients. Laparoscopic resection associated with less frequent epidural use ( P = .015), shorter time to full diet ( P = .030), and post-operative length of stay ( P = .009), compared to open resection. Average residual splenic volume after the laparoscopic Warshaw procedure was 70% of preoperative volume.

Discussion

Laparoscopic DP for pediatric SPT achieved similar oncologic goals to open resection. Splenic preservation was feasible with laparoscopy in most cases and was successfully supplemented with the Warshaw procedure, which has not been previously reported for SPT resection in children.
Tracheostomy Outcomes in COVID-19 Patients in a Low Resource Setting
Authors: Tang Liyang , Kim Celeste , Paik Connie , West Jonathan , Hasday Steven , Su Peiyi , Martinez Eduardo , Zhou Sheng , Clark Bhavishya , O’Dell Karla , Chambers Tamara N.
Published: December 2021

Objectives:

COVID-19 predominately affects safety net hospitals. Tracheostomies improve outcomes and decrease length of stay for COVID-19 patients. Our objectives are to determine if (1) COVID-19 tracheostomies have similar complication and mortality rates as non-COVID-19 tracheostomies and (2) to determine the effectiveness of our tracheostomy protocol at a safety net hospital.

Methods:

Patients who underwent tracheostomy at Los Angeles County Hospital between August 2009 and August 2020 were included. Demographics, SARS-CoV-2 status, body mass index (BMI), Charlson Co-morbidity Index (CCI), length of intubation, complication rates, decannulation rates, and 30-day all-cause mortality versus tracheostomy related mortality rates were all collected.

Results:

Thirty-eight patients with COVID-19 and 130 non-COVID-19 patients underwent tracheostomies. Both groups were predominately male with similar BMI and CCI, though the COVID-19 patients were more likely to be Hispanic and intubated for a longer time ( P = .034 and P < .0001, respectively). Both groups also had similar, low intraoperative complications at 2% to 3% and comparable long-term post-operative complications. However, COVID-19 patients had more perioperative complications within 7 days of surgery ( P < .01). Specifically, they were more likely to have perioperative bleeding at their tracheostomy sites ( P = .03) and long-term post-operative mucus plugging ( P < .01). However, both groups had similar 30-day mortality rates. There were no incidences of COVID-19 transmission to healthcare workers.

Conclusions:

COVID-19 tracheostomies are safe for patients and healthcare workers. Careful attention should be paid to suctioning to prevent mucus plugging.

The heliocentric path of the Moon
Authors: Gapaillard Jacques
Published: December 2021

In his Astronomie populaire, Camille Flammarion points out that the heliocentric path of the Moon, which, according to him, has generally been represented as a sinuous curve, is actually concave everywhere towards the Sun. Flammarion’s observation is the starting point of this study which goes backwards in time, via often misinformed authors, to the mathematician who first established this counterintuitive property by means of a purely geometrical proof. The story also includes a heated debate between readers of a British periodical. Beginning in France at the end of the 19th century, the journey finishes in Scotland in the first half of the previous century.
Periodontitis Risk Variants at SIGLEC5 Impair ERG and MAFB Binding
Authors: Mueller R. , Chopra A. , Dommisch H. , Schaefer A.S.
Published: December 2021

Periodontitis is a common complex inflammatory disease of the oral cavity. It is characterized by inflammation of gingival tissues and alveolar bone loss. Recently, a genome-wide association study and 2 genome-wide association study meta-analyses found 2 associated regions (haplotype blocks) at the inhibitory immune receptor gene SIGLEC5 to increase the risk for periodontitis. The aims of the current study were the identification of the putative causal variants underlying these associations, characterization of their molecular biological effects, and validation of SIGLEC5 as the target gene. We mapped the associated single-nucleotide polymorphisms to DNA elements with predictive features of regulatory functions and screened the associated alleles for transcription factor (TF) binding sites. Antibody electrophoretic mobility shift assays (EMSAs) with allele-specific probes were used to identify TF binding and to quantify allele-specific effects on binding affinities. Luciferase reporter assays were used to quantify the effect directions and allele-specific strength of the associated regulatory elements. We used CRISPR-dCas9 gene activation to validate SIGLEC5 as a target of the association. EMSA in peripheral blood mononuclear cells showed that E-26 transformation–specific TF-related gene (ERG) binds at rs11084095, with almost complete loss of binding at the minor A-allele. Allele-specific reporter genes showed enhancer function of the DNA sequence at rs11084095, which was abrogated in the background of the A-allele. EMSA in B lymphocytes showed that TF MAF bZIP (MAFB) binds at the common G-allele of rs4284742, whereas the minor A-allele reduced TF binding by 69%, corresponding to 9-fold reduction of luciferase reporter gene activity by the A-allele. Using CRISPR-dCas9, we showed that the enhancer at rs4284742 strongly activated SIGLEC5 expression, validating this gene as the target gene of the association. We conclude that rs11084095 and rs4284742 are putatively causal for the genome-wide significant associations with periodontitis at SIGLEC5 that impair ERG and MAFB binding, respectively.
Winning a battle against the odds: A cleaners’ campaign
Authors: Pannini Elisa
Published: December 2021

This article analyses a campaign urging a British university to re-establish in-house cleaning services after years of outsourcing. The small independent union leading the campaign began from an extremely low level of power resources and managed to build enough associational and societal power to win the dispute on cleaners’ working conditions. The study is based on participant observation of the union’s activities, document analysis and interviews. The article argues that the strategy emerging from the study, centred around three key strategies (collectivization of individual grievances, education, and disruption of core business activities), can be articulated in a process following the main categories of Mobilization Theory: organization, mobilization and collective action. Additionally, the union managed to conciliate servicing and organizing strategies, as well as attention to class-oriented and migrant-specific issues.
Active Fathers in the United States: Caught Between De-Gendering Care and Caring Masculinities
Authors: Adler Marina A.
Published: December 2021

The United States occupies a unique position among OECD countries because the US provides little policy support for working parents. Despite the resulting extreme time scarcity, US fathers perform similar amounts of child care as European fathers under more family-friendly policy conditions. Using recent national time use survey data, this paper examines whether time scarcity among American working parents, coupled with limited access to affordable child care and traditional masculine identity ideas, is associated with American fathers’ involvement in the daily care of their young children. Results show that fathers do one third of all care activities, contribute one third of the care time, and perform over one half of the 10 activities analyzed here daily. Multivariate analysis indicates that time scarcity, lack of alternative child care options, and traditional masculine identity affect the degree of fathers’ involvement in daily care activities with their under five year olds. Implications for the development of caring masculinities are discussed.
Increased muscle fiber fractional anisotropy value using diffusion tensor imaging after compression without fiber injury
Authors: Yokohama Takumi , Iwasaki Motoyuki , Oura Daisuke , Furuya Sho , Niiya Yoshimasa
Published: December 2021

Background

Recent studies have indicated that injuries such as muscle tears modify the microstructural integrity of muscle, leading to substantial alterations in measured diffusion parameters. Therefore, the fractional anisotropy (FA) value decreases. However, we hypothesized that soft tissue, such as muscle tissue, undergoes reversible changes under conditions of compression without fiber injury.

Purpose

To evaluate the FA change due to compression in muscle tissue without fiber injury.

Material and Methods

Diffusion tensor imaging (DTI) was performed on both feet of 10 healthy volunteers (mean age = 35.0 ± 10.39 years; age range = 23–52 years) using a 3.0-T magnetic resonance imaging (MRI) scanner with an eight-channel phased array knee coil. An MRI-compatible sphygmomanometer was applied to the individuals’ lower legs and individuals were placed in a compressed state. Then, rest intervals of 5 min were set in re-rest state after compression. The FA value, apparent diffusion coefficient (ADC), and eigenvalues (λ1, λ2, λ3) of the gastrocnemius and soleus muscle were measured at each state.

Results

The mean FA values increased in all muscles in a compressed state, while the mean λ3 decreased. In all muscles, significant differences were found between the rest and compressed states in terms of mean FA and λ3 ( P < 0.0001).

Conclusion

We confirmed the reversibility of the DTI metrics, which suggests that there was no muscle injury during this study. In cases of compression without fiber injury, the FA value increases, because fibers are strongly aligned in the longitudinal direction.

Authors: Alkindi Salam , Al-Ghadani Anwaar R , Al-Zeheimi Samah R , Alkindi Said Y , Fawaz Naglaa , Ballas Samir K , Pathare Anil V
Published: December 2021

Objective

To assess the clinical and laboratory predictors of venous thromboembolism (VTE) in patients with sickle cell anaemia (SCA) and its relationship to morbidity and mortality.

Methods

This retrospective case–control study analysed data from patients with SCA that experienced VTE compared with matched control patients with SCA but no VTE (2:1 ratio).

Results

A total of 102 patients with SCA were enrolled (68 cases with VTE and 34 controls). Amongst the 68 cases (median age, 29.5 years), 26 (38.2%) presented with isolated pulmonary embolism (PE). A higher prevalence of splenectomy (73.5% versus 35.3%) was observed in the cases compared with the controls. A significantly higher prevalence of central venous catheter (CVC) insertion (42.6% versus 8.8%) was observed in the cases compared with the controls. High white blood cell counts, serum lactic dehydrogenase (LDH), bilirubin and C-reactive protein (CRP) and low haemoglobin (Hb) and HbF were significant risk factors for VTE. Forty-two cases (61.8%) developed acute chest syndrome, 10 (14.7%) had a stroke and seven (10.3%) died.

Conclusions

VTE in patients with SCA has a high impact on morbidity and mortality. PE was the leading presentation of VTE, with CVC insertion, high LDH, bilirubin, CRP and white blood cell counts along with low Hb and HbF constituting other significant risk factors.

Authors: Zhao Yan , Fan Xin , Wen Jing , Gan Wenling , Xiao Guiyuan
Published: December 2021

Objective

This study aimed to investigate the catch-up growth pattern of singleton full-term small for gestational age (SGA) infants in the first year after birth.

Methods

A single-center retrospective cohort study was performed to assess singleton full-term SGA infants. Weight, length, and head circumference were measured at birth, and at 1, 3, 6, and 12 months of age.

Results

Two hundred ten SGA infants were included in this study. Boys (n = 90) and girls (n = 120) showed a similar gestational age, birth weight, and body length. Weight, length, and head circumference in SGA infants in all age groups increased with age, with the fastest growth stage from birth to 3 months. The speed of weight and head circumference catch-up was higher than that of body length. At 12 months, significant associations of height in boys with height of the fathers, mothers, and both parents combined appeared. The height of girls showed associations with the mothers’ and the parents’ height.

Conclusions

Full-term SGA infants grow rapidly after birth, with the fastest growth rate in the first 3 months, as examined by weight, body length, and head circumference. However, the catch-up speed of weight and body length were not balanced in this study.
Bridge Response and Heavy Truck Classification Framework Based on a Two-Step Machine Learning Algorithm
Authors: Mete Fiorella , Corr David J. , Wilbur Michael P. , Chen Ying
Published: December 2021

Collecting information on heavy trucks and monitoring the bridges which they regularly cross is important for many facets of infrastructure management. In this paper, a two-step algorithm is developed using bridge and truck data, by deploying sequentially unsupervised and supervised machine learning techniques. Longitudinal clustering of bridge data, concerning strain waveforms, is adopted to perform the first step of the algorithm, while image visual inspection and classification tree methods are applied to truck data concurrently in the second step. Both bridge and truck traffic must be monitored for a limited, yet significant, amount of time to calibrate the algorithm, which is then used to build a classification framework. The framework provides the same benefits of two data collection systems while only one needs to be operative. Depending on which monitoring system remains available, the framework enables the use of bridge data to identify the truck’s profile which generated it, or to estimate bridge response given the truck’s information. As a result, the present study aims to provide decision-makers with an effective way to monitor the whole bridge-traffic system, bridge managers to plan effective maintenance, and policymakers to develop ad hoc regulations.
Optimization of Multi-Period Rail Procurement Plan
Authors: Shih Hsin-Cheng , Yeh Chih-Heng , Lai Yung-Cheng
Published: December 2021

Rail is one of the most expensive assets in railway infrastructure. Therefore, a well-prepared rail procurement plan could benefit the asset management. For the metro system in Taiwan, the rail procurement plan includes two major uncertainties, namely, currency rates and the global steel price. In this study, we propose deterministic and stochastic optimization models using a scenario-generation process to minimize the expected cost of the rail procurement plan. Results from the case studies demonstrate that the proposed models can successfully incorporate the uncertainties and obtain the optimal procurement plan. The sensitivity analysis on budget, storage capacity, and expiration period also provides the metro operator the best strategy to further lower the procurement cost. Adopting these models in rail procurement planning can improve the process and results of rail asset management.
The Minimal Clinically Important Difference: A Review of Clinical Significance
Authors: Bloom David A. , Kaplan Daniel J. , Mojica Edward , Strauss Eric J. , Gonzalez-Lomas Guillem , Campbell Kirk A. , Alaia Michael J. , Jazrawi Laith M.
Published: December 2021

Background:

The minimal clinically important difference (MCID) is a term synonymous with orthopaedic clinical research over the past decade. The term represents the smallest change in a patient-reported outcome measure that is of genuine clinical value to patients. It has been derived in a myriad of ways in existing orthopaedic literature.

Purpose:

To describe the various modalities for deriving the MCID.

Study Design:

Narrative review; Level of evidence, 4.

Methods:

The definitions of common MCID determinations were first identified. These were then evaluated by their clinical and statistical merits and limitations.

Results:

There are 3 primary ways for determining the MCID: anchor-based analysis, distribution-based analysis, and sensitivity- and specificity-based analysis. Each has unique strengths and weaknesses with respect to its ability to evaluate the patient’s clinical status change from baseline to posttreatment. Anchor-based analyses are inherently tied to clinical status yet lack standardization. Distribution-based analyses are the opposite, with strong foundations in statistics, yet they fail to adequately address the clinical status change. Sensitivity and specificity analyses offer a compromise of the other methodologies but still rely on a somewhat arbitrarily defined global transition question.

Conclusion:

This current concepts review demonstrates the need for (1) better standardization in the establishment of MCIDs for orthopaedic patient-reported outcome measures and (2) better study design—namely, until a universally accepted MCID derivation exists, studies attempting to derive the MCID should utilize the anchor-based within-cohort design based on Food and Drug Administration recommendations. Ideally, large studies reporting the MCID as an outcome will also derive the value for their populations. It is important to consider that there may be reasonable replacements for current derivations of the MCID. As such, future research should consider an alternative threshold score with a more universal method of derivation.
Remaining Large Bone Fragment of a Bony Bankart Lesion in Shoulders With a Subcritical Glenoid Defect: Association With Recurrent Anterior Instability
Authors: Nakagawa Shigeto , Hirose Takehito , Uchida Ryohei , Ohori Tomoki , Mae Tatsuo
Published: December 2021

Background:

A preoperative glenoid defect of 13.5% or larger is recognized as a subcritical glenoid defect at arthroscopic Bankart repair (ABR) for collision/contact athletes or military personnel.

Purpose:

To clarify the prevalence and size of remaining bone fragments in shoulders with a subcritical glenoid defect at recurrent anterior instability and to investigate the influence on postoperative recurrence after ABR for younger competitive athletes.

Study Design:

Cohort study; Level of evidence, 4.

Methods:

The study included 96 shoulders with recurrent instability that underwent ABR between July 2011 and March 2018 for shoulders with a subcritical glenoid defect. The patients were divided into 2 groups according to the glenoid defect size (13.5%-<20%, medium; ≥20%, large). The bone fragment size in each defect group was retrospectively investigated and classified into 4 groups (no, 0%; small, >0%-<5%; medium, 5%-<10%; large, ≥10%). The postoperative recurrence rate for each combination of glenoid defect size and bone fragment size was investigated for competitive athletes aged <30 years. The fragments, when present, were repaired to the glenoid.

Results:

The glenoid defect size was 13.5%-<20% in 60 shoulders (medium defect group) and ≥20% in 36 shoulders (large defect group). The mean bone fragment size was 6.7% ± 5.1% and 8.9% ± 4.9%, respectively ( P = .042). In the medium defect group, there were 15 shoulders (25%) without a bone fragment, 6 shoulders (10%) with a small fragment, 23 shoulders (38.3%) with a medium fragment, and 16 shoulders (26.7%) with a large fragment. In the large defect group, the respective numbers were 2 shoulders (5.6%), 6 shoulders (16.7%), 14 shoulders (38.9%), and 14 shoulders (38.9%). A medium or large bone fragment was more common in the large defect group ( P = .252). Among 64 younger competitive athletes who underwent ABR with a minimum of 2 years of follow-up, postoperative recurrence was recognized in 7 of 38 (18.4%) athletes in the medium defect group, but it was not recognized in any of the 26 athletes in the large defect group ( P = .036). Postoperative recurrence was recognized in 4 of 12 (33.3%) athletes with a small fragment or no fragment and in 3 of 52 (5.8%) athletes with a medium or large fragment ( P = .019).

Conclusion:

A larger bone fragment frequently remained in shoulders with a subcritical glenoid defect at recurrent instability. The postoperative recurrence rate after ABR for younger competitive athletes was low when a remaining larger bone fragment was repaired.
Telemedicine Readiness Across Medical Conditions in a US National Representative Sample of Older Adults
Authors: Rodríguez-Fernández Jorge M. , Danies Emily , Hoertel Nicolas , Galanter William , Saner Hugo , Franco Oscar H.
Published: December 2021

Telemedicine has provided older adults the ability to seek care remotely during the coronavirus disease (COVID-19) pandemic. However, it is unclear how diverse medical conditions play a role in telemedicine uptake. A total of 3379 participants (≥65 years) were interviewed in 2018 as part of the National Health and Aging Trends Study. We assessed telemedicine readiness across multiple medical conditions. Most chronic medical conditions and mood symptoms were significantly associated with telemedicine unreadiness, for physical or technical reasons or both, while cancer, hypertension, and arthritis were significantly associated with telemedicine readiness. Our findings suggest that multiple medical conditions play a substantial role in telemedicine uptake among older adults in the US. Therefore, comorbidities should be taken into consideration when promoting and adopting telemedicine technologies among older adults.
The Impact of Death Anxiety, Meaning and Coping on Posttraumatic Stress Disorder and Psychiatric Co-Morbidity Among Iraqi Civilians Exposed to a Car Bomb Attack A Latent Class Analysis
Authors: Chung Man Cheung , Freh Fuaad Mohammed
Published: December 2021

Much has been documented that the experience of a bombing is associated with posttraumatic stress disorder and psychiatric co-morbidity. Whether the co-existing relationship between death anxiety, meaning in life and coping styles would influence the aforementioned association is unknown. The present study aimed to identify latent classes of victims with different levels of death anxiety, meaning in life and coping styles, and to examine whether the severity of PTSD and co-morbid psychiatric symptoms differed between classes. One hundred and eighty-five victims who had experienced the first car bombing completed a demographic page, the Posttraumatic Stress Diagnosis Scale, General Health Questionnaire-28, Multidimensional Fear of Death Scale, Meaning in Life Questionnaire and Coping Responses Inventory. The results showed that 82% and 18% of the victims met the criteria for PTSD and no-PTSD, respectively. Four classes of victims were identified: Class 1 victims were approach copers with low levels of death anxiety and meaning. Class 2 victims were minimal copers with high levels of death anxiety and meaning. Class 3 victims were approach copers with a high level of death anxiety and meaning. Class 4 victims were avoidance copers with high levels of death anxiety. Individuals in Class 1 reported significantly lower levels of PTSD and psychiatric co-morbidity than the other three classes. Class 3 victims also reported significantly lower levels of psychiatric co-morbidity than Class 2 victims. To conclude, victims exposed to a car bombing were likely to exhibit posttraumatic stress symptoms in addition to other psychological symptoms. The severity of these symptoms tended to be lower among those who had little fear of death, did not search for meaning in life and approached their distress proactively.
Improving Living Conditions, Deepening Class Divisions: Hungarian Class Structure in International Comparison, 2002–2018
Authors: Huszár Ákos , Füzér Katalin
Published: December 2021

This article investigates the changing relationship of class and the living conditions of individuals in Hungary in comparison with other European countries. Our central question is to what extent class position determines the material living conditions of individuals in Hungary, how this relationship has changed, and how significant it is compared to other European countries. Our analysis is a direct test of the death-of-class thesis in one of the core fields of class analysis. Our results show that there has been a rapid and large-scale restructuring of Hungarian society after 2010, with two notable tendencies. The first is an overall improvement of material living conditions at all levels of the class structure, the other is the gradual solidification and polarisation of class structure.

Published: December 2021

Purpose

This study aims to test the effect of an information and support intervention on physical activity (PA) in women aged 50+ years.

Design

Randomized wait-list controlled trial.

Setting

Sydney, Australia.

Sample

126 female university and health service employees, aged 50+.

Intervention

Information session, activity tracker, regular motivational emails.

Measures

Proportion achieving ≥ 10,000 steps/day (primary outcome), daily step count, proportion meeting 150 mins/week of moderate to vigorous PA (MVPA), self-reported PA.

Analysis

Odds-ratios and general linear regression models.

Results

At 3 months, the intervention group reported significantly more vigorous PA (1.04 hours, 95% CI 0.24 to 1.85, P = .01, measured by IPAQ), were more likely to achieve 300 mins/week of MVPA (OR = 1.98, 95% CI 0.89 to 4.36, P = .09, measured by Actigraph) than the control wait-list group, and reported adopting PA promotion strategies (technology = 31/58% or goal-setting = 39/74%). No significant between-group differences in the primary outcome were detected (1.39, 95% CI 0.61 to 3.18, P = .44).

Conclusions

This low-dose intervention significantly increased self-reported vigorous PA time and non-significantly increased the proportion of people achieving 300 mins/week of MVPA but did not significantly increase the proportion of participants achieving 10,000 steps/day. Relatively small effects may be important at a population level given the minimal resources needed to deliver this intervention.
“This is Not Who We Are”: Students Leading for Anti-Racist Policy Changes in Alexandria City Public Schools, Virginia
Authors: Mansfield Katherine Cumings , Lambrinou Marina
Published: December 2021

This paper centers the voices of students who successfully struggled alongside justice-minded school board members and other concerned citizens to create anti-racist policy changes in Alexandria City Public Schools, Virginia. Specifically, we examine the history behind, and political processes involved with, changing the names of two local schools due to the racist political commitments of their namesakes. Lessons learned include the need to carefully structure the policy change process to include students, families, and other community members in critical dialog and amplify the voices of those most impacted by the structural racism that needs to be dismantled: The students.
“Mo” Together or Alone? Investigating the Role of Fundraisers’ Networks in Online Peer-to-Peer Fundraising

Published: December 2021

In online peer-to-peer fundraising, individual fundraisers, acting on behalf of nonprofit organizations, mobilize their social networks using social media to request donations. Whereas existing studies focus on networks of donors to explain success, we examine the role of the networks of fundraisers and their effect on fundraising outcomes. By drawing on social capital and network theories, we investigate how social capital derived from social media networks and fundraising groups explains individual fundraising success. Using the Movember health campaign on Twitter as an empirical context, we find that fundraising success is associated with a moderate level of centrality in social media networks and moderate group network size. In addition, we find that fundraisers interact only marginally on social media but prefer to connect with each other outside these platforms and engage in group fundraising. Our article contributes to research on fundraising and social networks and provides recommendations for practice.
Nanoparticle aggregation kinematics on the quadratic convective magnetohydrodynamic flow of nanomaterial past an inclined flat plate with sensitivity analysis

Published: December 2021

The study focuses on the aggregation kinematics in the quadratic convective magneto-hydrodynamics of ethylene glycol-titania ([Formula: see text]) nanofluid flowing through an inclined flat plate. The modified Krieger-Dougherty and Maxwell-Bruggeman models are used for the effective viscosity and thermal conductivity to account for the aggregation aspect. The effects of an exponential space-dependent heat source and thermal radiation are incorporated. The impact of pertinent parameters on the heat transfer coefficient is explored by using the Response Surface Methodology and Sensitivity Analysis. The effects of several parameters on the skin friction and heat transfer coefficient at the plate are displayed via surface graphs. The velocity and thermal profiles are compared for two physical scenarios: flow over a vertical plate and flow over an inclined plate. The nonlinear problem is solved using the Runge–Kutta-based shooting technique. It was found that the velocity profile significantly decreased as the inclination of the plate increased on the other hand the temperature profile improved. The heat transfer coefficient decreased due to the increase in the Hartmann number. The exponential heat source has a decreasing effect on the heat flux and the angle of inclination is more sensitive to the heat transfer coefficient than other variables. Further, when radiation is incremented, the sensitivity of the heat flux toward the inclination angle augments at the rate 0.5094% and the sensitivity toward the exponential heat source augments at the rate 0.0925%. In addition, 41.1388% decrement in wall shear stress is observed when the plate inclination is incremented from [Formula: see text] to [Formula: see text].
Strength testing of low-cost 3D-printed transtibial prosthetic socket

Published: December 2021

Measurement and production of traditional prosthetic sockets are time-consuming, labor-intensive, and highly dependent on the personnel involved. An alternative way to make prostheses is using computer-aided design (CAD) and computer-aided manufacturing (CAM). Fused Filament Fabrication (FFF) may be an alternative to make low-cost prosthetic sockets. This study investigates the tensile properties of potential printing materials suitable for FFF according to ISO527 (Standard Test Method for Tensile Properties of Plastics). To ensure that FFF-printed sockets are safe for patient usage, the structural integrity of the 3D-printed prosthesis will be investigated according to ISO10328 (International Standard Structural Testing of Lower Limb Prostheses). Tough PLA was the most suitable print material according to ISO 527 testing. The Tough PLA printed socket completed 2.27 million cycles and a static test target value of 4025 N. Future research remains necessary to continue testing new potential materials, improve print settings, and improve the socket design for the production of FFF-printed transtibial prosthetic sockets. FFF using Tough PLA can be used to create transtibial prostheses that almost comply with the International Standard for Structural Testing of Lower Limb Prostheses.
Statistical reproducibility for pairwise t-tests in pharmaceutical research

Published: December 2021

This paper investigates statistical reproducibility of the [Formula: see text]-test. We formulate reproducibility as a predictive inference problem and apply the nonparametric predictive inference method. Within our research framework, statistical reproducibility provides inference on the probability that the same test outcome would be reached, if the test were repeated under identical conditions. We present an nonparametric predictive inference algorithm to calculate the reproducibility of the [Formula: see text]-test and then use simulations to explore the reproducibility both under the null and alternative hypotheses. We then apply nonparametric predictive inference reproducibility to a real-life scenario of a preclinical experiment, which involves multiple pairwise comparisons of test groups, where different groups are given a different concentration of a drug. The aim of the experiment is to decide the concentration of the drug which is most effective. In both simulations and the application scenario, we study the relationship between reproducibility and two test statistics, the Cohen’s [Formula: see text] and the [Formula: see text]-value. We also compare the reproducibility of the [Formula: see text]-test with the reproducibility of the Wilcoxon Mann–Whitney test. Finally, we examine reproducibility for the final decision of choosing a particular dose in the multiple pairwise comparisons scenario. This paper presents advances on the topic of test reproducibility with relevance for tests used in pharmaceutical research.

An Affair to Remember: A Mixed-Methods Survey Examining Therapists’ Experiences Treating Infidelity
Authors: Irvine Taylor J. , Peluso Paul R.
Published: December 2021

In this mixed-methods study, we analyzed data from 351 couple therapists who completed our Therapists' Experiences Treating Infidelity (TETI) survey. The present survey is a follow-up of previous iterations that examined therapists' attitudes toward infidelity and affair recovery treatment. Our TETI survey provided additional questions pertaining to therapists' personal history with affairs and perceptions on current research and training standards. Results showed that various therapist and couple factors serve to impede affair recovery treatment. Additionally, this survey revealed several similarities in therapists' attitudes from prior surveys, despite decades having passed between when the present survey and previous versions. In this article, we (a) outline findings from this mixed-methods survey, (b) discuss implications for the field, and (c) offer directions for future research.

Authors: Koltz Rebecca L. , Koltz Daniel J.
Published: December 2021

Art coupled with nature provides numerous therapeutic benefits to reduce stress and reframe aging for older adults. This article outlines five eco-art activities to use in the context of individual or family counseling. Stress and the aging process is addressed, as well as the numerous therapeutic benefits of nature for the aging family. Nature combined with art increases self-expression, social engagement, and sensory stimulation. Nature-based activities decrease stress and anxiety and recreate purpose and meaning using the metaphors that exist in nature. The proposed activities focus on themes found in nature to reduce stress and reframe aging for individuals and families.
