The ecology for fostering the musical creativity of students with intellectual disabilities
Authors: Wong Marina Wai-Yee
Published: July 2021

Students with intellectual disabilities in Hong Kong are placed in special schools in their neighborhoods according to their categories of intellectual disabilities. Music teachers in these special schools implement a school-based music curriculum that includes the learning objective “creativity and imagination.” Reporting a qualitative multiple-case study with purposeful sampling and face-to-face interviews, this study poses the research question “What are the ecological elements for fostering the musical creativity of students with intellectual disabilities?” Respondents identify five elements as essential in fostering their students’ musical creativity: (1) opportunity for play and exploration; (2) providing support guidance and demonstration; (3) opportunity to develop a sense of engagement; (4) opportunity for making choices; and (5) providing positive reinforcement and feedback. A discussion of this data reveals how the dual impact of lacking professional training in music education for students with intellectual disabilities and cultural perspective diminishes respondents’ expectations of their students’ creative capacity.
Revisiting norms of citizenship in times of democratic change
Authors: Schnaudt Christian , van Deth Jan W , Zorell Carolin , Theocharis Yannis
Published: July 2021

Over the last two decades, scholars have investigated norms of citizenship by focussing primarily on ‘dutiful’ and ‘engaged’ norms. In the meantime, contemporary democracies have witnessed growing demands for more sustainable styles of living and increasing public support for authoritarian and populist ideas. These developments point to both a change and an expansion of conventional understandings and conceptions of what a ‘good citizen’ in a democratic polity ought to do. Specifically, they raise questions about whether demands for more sustainability and increasing support for populist ideas establish new facets of democratic citizenship, and if so, how they can be meaningfully incorporated into existing images of citizenship. This study provides a re-conceptualization of citizenship norms and empirically tests a new measurement instrument using original data collected in Germany in 2019. The empirical application of an expanded set of items demonstrates the existence of more variegated facets of norms of citizenship, including norms to safeguard a sustainable future and distinct populist facets emphasizing the relevance of trust in authorities and experts as well as reliance on feelings and emotions. Contemporary conceptions of citizenship thus go beyond conventional distinctions between dutiful and engaged norms of citizenship.
The relational and mental health payoffs of staying gritty during the COVID-19 pandemic: A cross-cultural study in the Philippines and the United States
Authors: Datu Jesus Alfonso D. , Fincham Frank D.
Published: July 2021

This study examined how the triarchic model of grit (i.e., perseverance of effort, consistency of interests, and adaptability to situations) is related to cultivation of genuine happiness, loneliness, and COVID-19 anxiety in American ( n = 643) and Filipino ( n = 546) undergraduate students. It also explored whether grit had indirect effects on such social and well-being outcomes via relatedness needs satisfaction and meaning in life. Results of structural equation modeling demonstrated that whereas all grit dimensions were linked to increased relatedness needs satisfaction and meaning in life in the United States, only consistency and adaptability were associated with such constructs in the Philippines. Meaning in life was related to increased cultivation of happiness and reduced loneliness in both societies. Relatedness needs satisfaction was associated with higher happiness as well as decreased COVID-19 anxiety and loneliness in the United States and the Philippines. Finally, evidence supported indirect effects of of selected grit’s dimensions on mental health outcomes via relatedness needs satisfaction and meaning in life in both settings. This research complements existing literature on the relational and psychological benefits of staying gritty in different societies.
Rejection sensitivity and interaction quality in everyday life
Authors: Bayer Joseph B. , Triệu Penny , Ellison Nicole , Schoenebeck Sarita Y. , Falk Emily B.
Published: July 2021

The elevated satisfaction that comes from interacting with close ties, as opposed to distal ties, is well-established in past research. What remains less clear is how the quality of daily interactions between close versus distal ties may vary as a function of personality. Drawing on data from a 2-week experience sampling study ( N = 108 participants, N = 7755 observations), we consider how trait rejection sensitivity (RS)—or the tendency to worry about potential social rejection—interacts with perceived closeness and interaction channel (i.e., face-to-face vs. technology-mediated) in daily life. We find that individuals who are high (vs. low) in rejection sensitivity not only view distal tie interactions as less satisfying, they also perceive close tie exchanges as more enjoyable and supportive—but only for technology-mediated (vs. face-to-face) interactions. We also find that individuals who are high in rejection sensitivity have higher variability in the perceived quality of their interactions. These findings demonstrate the interlocked factors of personality tendencies, perceived closeness, and interaction channel in shaping the variability in the quality of daily interactions.
Filling the void: Grieving and healing during a socially isolating global pandemic
Authors: Scheinfeld Emily , Barney Kendyl , Gangi Katlyn , Nelson Erin C. , Sinardi Catherine C.
Published: July 2021

The COVID-19 pandemic has altered life dramatically, including grieving practices. This study examines how people grieved death when they were unable to engage in traditional mourning rituals. Participants shared ways their experiences with grief were affected by the pandemic through themes of (1) physical isolation, including feeling together while apart, and, (2) challenges to grief management, like lack of nonverbal communication and feeling delegitimized. Participants also spoke of memorable messages deemed helpful or hurtful, including (1) emphasizing the death over the loss, (2) community, and (3) faith and advice. The findings yield implications regarding the nature of communal coping, flexibility to grieving practices, and disenfranchised grief during a global pandemic.
Local economic governance strategies in the UK’s post-industrial cities and the challenges of improving local work and employment conditions
Authors: Yates Edward , Clark Ian , Rossiter William
Published: July 2021

This study examines two inter-connected issues: the local economic governance strategies pursued by English local authorities in the post-2007 Crisis austerity period, and the impact of these strategies on local work and employment conditions. The study draws on interview data, policy documents and statistical datasets from an analysis of two English localities to understand how local authorities responded to the economic pressures resulting from the 2007 Crisis and subsequent imposition of austerity policies. The study finds local authorities engaged in various forms of entrepreneurial and austerity urbanist policies under conditions of tight budgetary constraints, resulting in an increased role for the private sector as a vehicle to generate jobs and increase tax revenue. This process has increased the influence of private sector actors within local government, part of a longer term trend. This study presents evidence to illustrate why this scenario is problematic for improving work and employment conditions, chiefly due to an unwillingness to progressively regulate work, and a prioritising of job quantity in terms of total employment, rather than favouring the creation of sustainable, high-quality local employment.

Authors: Paul Pradip , Nadella Ravi Kumar , Sen Somdatta , Ithal Dhruva , Mahadevan Jayant , Reddy Y C Janardhan , Jain Sanjeev , Purushottam Meera , Viswanath Biju
Published: July 2021

Background:

The association of the Val66Met (rs6265) polymorphism in the brain-derived neurotrophic factor ( BDNF) gene with bipolar disorder (BD) and response to lithium treatment has been suggested, though inconsistently. The considerable diversity of allele frequency across different populations contributes to this. There is no data from South Asia till date. Hence, we examined the association of this polymorphism in BD cases from India, and its association with lithium treatment response.

Methods:

BD patients ( N = 301) were recruited from the clinical services of National Institute of Mental Health and Neurosciences (NIMHANS), India. Lithium treatment response for 190 BD subjects was assessed using Alda scale by NIMH life charts. Patients with total score ⩾7 were defined as lithium responders ( N = 115) and patients with score <7 were defined as lithium non-responders ( N = 75). Healthy controls ( N = 484) with no lifetime history of neuropsychiatric illness or a family history of mental illness were recruited as control set. Genotyping was performed by TaqMan genotyping assay.

Results:

Genotype and allele frequency of BDNF Val66Met SNP was significantly different (χ2 = 7.78, p = 0.02) in cases compared to controls, and the Val(G) allele was more frequent (χ2 = 7.08, p = 0.008) in BD patients. However, no significant difference is noted in genotype or allele frequencies of this polymorphism between the lithium responders and non-responders.

Conclusions:

The Val(G) allele of BDNF Val66Met polymorphism is associated with risk of BD in this sample, but it is not related to response to lithium.
Sampling Engagement in Shared Reading Activities With Children With Autism Spectrum Disorder: A Generalizability Study
Authors: Ford Andrea L. B. , Fleury Veronica P.
Published: July 2021

Researchers seeking to make valid conclusions about engagement for young children with autism spectrum disorder (ASD) must first determine the reliability of estimates obtained across the conditions sampled. Working from that premise, we conducted a secondary data analysis of shared book readings between caregivers and their children with ASD, examining the contribution of measurement error on estimates of four states of child engagement. Caregivers read two different book types, each three times, with their children. With book type and occasion as measurement facets, we conducted a generalizability study and a series of decision studies. With the interaction of Persons × Book Type × Occasion contributing the most measurement error for four engagement variables, we only found stable estimates for unengaged behaviors. For the active engagement, visual engagement, and disruptive variables, 4, 5, and more than 10 book types, respectively, were necessary to obtain stable estimates across two occasions.
Symbolic Representation, Cooperation, and Undocumented Immigrants: The Role of Representation in Improving Assessments of Cooperative Behaviors in Education
Authors: Hawes Daniel P.
Published: July 2021

This article explores how symbolic representation can increase behaviors associated with cooperation among immigrants in an educational setting. It posits that, due to a lack of trust and efficacy in public institutions, undocumented immigrants are less likely to engage in activities that are conducive to cooperation and compliance. However, this relationship is conditional on the presence of passive representation. In settings where immigrant interests are represented, even passively, immigrants are more likely to engage in cooperative behaviors. Using data from Texas school districts, the analysis finds some support that passive representation can enhance symbolic representation among this population. It finds that assessments of immigrants’ cooperative behaviors are likely to decrease as the size of the undocumented student population increases. However, this is only the case in schools with low levels of representation. This supports the expectation that symbolic representation can enhance assessments of cooperative behaviors among undocumented immigrants.
Radiomics and machine learning to predict aggressive type 2 endoleaks after endovascular aneurysm repair: a proof of concept
Authors: Charalambous Stavros , Klontzas Michail E. , Kontopodis Nikolaos , Ioannou Christos V , Perisinakis Kostas , Maris Thomas G , Damilakis John , Karantanas Apostolos , Tsetis Dimitrios
Published: July 2021

Background

Persistent type 2 endoleaks (T2EL) require lifelong surveillance to avoid potentially life-threatening complications.

Purpose

To evaluate the performance of radiomic features (RF) derived from computed tomography angiography (CTA), for differentiating aggressive from benign T2ELs after endovascular aneurysm repair (EVAR).

Material and Methods

A prospective study was performed on patients who underwent EVAR from January 2018 to January 2020. Analysis was performed in patients who were diagnosed with T2EL based on the CTA of the first postoperative month and were followed at six months and one year. Patients were divided into two groups according to the change of aneurysm sac dimensions. Segmentation of T2ELs was performed and RF were extracted. Feature selection for subsequent machine-learning analysis was evaluated by means of artificial intelligence. Two support vector machines (SVM) classifiers were developed to predict the aneurysm sac dimension changes at one year, utilizing RF from T2EL at one- and six-month CTA scans, respectively.

Results

Among the 944 initial RF of T2EL, 58 and 51 robust RF from the one- and six-month CTA scans, respectively, were used for the machine-learning model development. The SVM classifier trained on one-month signatures was able to predict sac expansion at one year with an area under curve (AUC) of 89.3%, presenting 78.6% specificity and 100% sensitivity. Similarly, the SVM classifier developed with six-month radiomics data showed an AUC of 95.5%, specificity of 90.9%, and sensitivity of 100%.

Conclusion

Machine-learning algorithms utilizing CTA-derived RF may predict aggressive T2ELs leading to aneurysm sac expansion after EVAR.
Evaluation of bone grafting for treatment of low-grade chondrosarcoma of long bones
Authors: Zhang Guofeng , Cheon Sangho , Park Ilhyung
Published: July 2021

Objective

To retrospectively analyze the biological compatibility and oncologic outcomes of autogenous, allogeneic, or combined bone grafting.

Methods

From April 2000 to December 2016, 37 patients with histologically confirmed low-grade intramedullary chondrosarcoma of the long bones at Kyungpook National University Hospital were enrolled in this retrospective study. All 37 patients underwent intralesional curettage (with or without cryotherapy) followed by bone grafting. Among the 24 patients who underwent cryotherapy, 13 were treated by prophylactic internal fixation (10 in the femur, 1 in the tibia, and 2 in the humerus). Thirteen patients underwent the same treatment without cryotherapy, whereas 12 did not undergo preventive internal fixation.

Results

A single intraoperative fracture was managed by plate fixation. One patient who underwent cryotherapy and internal fixation developed a fracture distal to the operation site 25 days after surgery, and this fracture was repaired with a long plate. None of the 37 patients showed any recurrence or metastasis.

Conclusions

Adequate intralesional curettage (with or without cryosurgery) combined with bone grafting using autogenous and allogeneic bone chips was effective for the treatment of low-grade intramedullary chondrosarcoma. Therefore, prophylactic internal fixation using a plate is recommended in the cryotherapy of definite cortical invasion in weight-bearing bones.
Pediatric sigmoid volvulus of an extremely long sigmoid colon with hypoganglionosis: a case report
Authors: Horvat Matjaž , Hazabent Marko , Sekej Marjan , Kljaić Dujić Milka
Published: July 2021

Sigmoid volvulus is an extremely rare cause of intestinal obstruction in pediatric patients. This condition occurs when a redundant sigmoid loop with a narrow mesenteric base of attachment to the posterior abdominal wall rotates around its mesenteric axis. This situation might result in vascular occlusion and large bowel obstruction. There are only a few predisposing factors of sigmoid volvulus, such as a long-term history of constipation or pseudo-obstruction with an excessive sigmoid colon. Underlying hypoganglionosis can also lead to large bowel obstruction. There have only been two reported cases of hypoganglionosis with sigmoid volvulus, and both were in adults. Sigmoid volvulus usually presents with abdominal pain, nausea, vomiting, constipation and abdominal distension, an absence of stool, or the presence of melenic stool in the rectum. Initial treatment options are non-surgical for stable patients, although surgical management might be necessary. If sigmoid volvulus is not recognized and resolved, it may lead to serious complications and death. Pediatric sigmoid volvulus is frequently the fulminant type, and therefore, a decision about treatment must be prompt. We present an unusual pediatric case of an extremely long sigmoid colon with hypoganglionosis, which twisted and caused obstruction. This condition was resolved with surgical resection.
Oblique lateral interbody fusion to treat lumbar spinal stenosis in a patient with situs inversus totalis: a case report
Authors: Yang FengKai , Dou ChenTao , Cheng XiaoKang , Chen Bin
Published: July 2021

Oblique lateral interbody fusion (OLIF) is a minimally invasive spinal surgery that is popular for lumbar degeneration and spinal deformity treatment because it causes minimal damage to the stability of the intervertebral structures. However, when encountering abnormal anatomical structures caused by situs inversus, surgical routes must be adjusted to avoid serious complications. A 42-year-old woman with lumbar spinal stenosis presented to our hospital. Preoperative X-ray and computed tomography indicated situs inversus totalis, with the abdominal aorta and inferior vena cava reversed. We established an appropriate surgical approach for OLIF via the right abdomen according to the characteristics of the anatomical structures. Postoperative X-rays showed adequate positioning of the interbody fusion cage and internal fixation screws. At the 3-month follow-up, the patient reported resolution of her symptoms. Vascular variations caused by situs inversus totalis can affect the course of OLIF. Understanding the unique anatomical structure in such patients is crucial for successful surgery and to avoid intraoperative complications.

Published: July 2021

Stevens–Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a life-threatening mucocutaneous disease that is predominantly drug-induced. Warfarin is the most commonly used drug for long-term anti-coagulant therapy; however, warfarin-induced SJS/TEN is seldom reported. In this study, we presented the case of a 61-year-old man who developed SJS after receiving multiple-drug therapy following aortic valve replacement surgery. The patient was diagnosed with drug-induced liver injury (DILI) based on significantly abnormal liver function test results. Warfarin was identified as the culprit drug using the algorithm of drug causality for epidermal necrolysis (ALDEN) score, enzyme-linked immunospot (ELISPOT) assay, and Roussel Uclaf Causality Assessment Method (RUCAM). After warfarin discontinuation and corticosteroid therapy, the lesions and liver function test findings improved. Human leukocyte antigen typing was conducted to detect the risk allele. To our knowledge, this is the first reported case of warfarin-induced SJS/TEN with DILI. This case suggests that commonly used and safe pharmaceutical agents such as warfarin can potentially cause serious adverse events, including SJS/TEN and DILI. The application of ALDEN, the ELISPOT assay, and RUCAM could be useful in identifying culprit drugs.
Household Transportation Energy Affordability by Region and Socioeconomic Factors
Authors: Zhou Yan , Aeschliman Spencer , Gohlke David
Published: July 2021

Transportation fuel is an important component of household budgets, as 3.3% of total household expenditures are for vehicle fuel nationwide and over 50% of annual household expenditures on energy are for transportation. These average values vary geographically, and higher energy cost burdens are faced by households with lower incomes. Defining transportation energy affordability burden as the percentage of annual household income spent on vehicle fuel, this study aims to quantify affordability as a function of household characteristics and geography. Through analysis at the census tract level, this study (i) projects annual household vehicle miles traveled (VMT) based on demographic factors using machine-learning techniques, (ii) estimates local differences in vehicle fuel economy and fuel price, and (iii) quantifies resulting transportation energy affordability by census tract. This study found that the average burden by tract varies from 0.15% to 8%. The variation in affordability can be largely explained by income level and vehicle fuel efficiency. Suburban and rural households spend more on transportation energy compared with urban households because of the usage of less fuel-efficient vehicle technologies and higher annual VMT. Lower-income groups have a wide distribution of the percentage of income spent on transportation energy, 1.2% to 8%, whereas the range for the highest income group ($125,000+) is from 0.15% to 3.9%. This detailed transportation energy affordability analysis provides a better understanding of regional variations in household travel behavior, helps to determine where fuel-efficient vehicle technologies are more likely to be used, and improves estimates of vehicle ownership costs.

Published: July 2021

Understanding speed selection behavior of drivers following speed limit increases is critically important. To date, the literature has largely focused on freeways and the effects of speed limit changes on two-lane highways remains under researched. Prior research has generally focused on changes to mean speeds, although the speeds of both the highest and lowest drivers are also of great interest. This study investigates trends in free-flow travel speeds following 2017 legislation that increased the posted speed limit from 55 to 65 mph on 943 mi of rural highways in Michigan. Speed data were collected for over 46,000 drivers at 67 increase segments where speed limit increased and 28 control segments where speed limits remained unchanged, before and during each of the two successive years following the speed limit increases. Site-specific traffic, geometric, and cross-sectional information was also collected. Impacts of the speed limit increases on the 15th, 50th, and 85th percentile speeds were evaluated using quantile regression. Separate analyses were conducted for passenger cars and heavy vehicles. Locations where the speed limits were raised experienced increases in travel speeds ranging from 2.8 to 4.8 mph. The control sites experienced marginal changes in speeds, which suggests that any spillover effects of the higher speed limits have been limited. Significant differences were observed across the quantiles with respect to the effects of the speed limit increases, as well as numerous site-specific variables of interest. The results provide important insights about the nature of driver speed selection and the impacts of speed limit increases.
Bicycle Level of Service: Proposed Updated Pavement Quality Index
Authors: Huang Jiayun , Fournier Nicholas , Skabardonis Alexander
Published: July 2021

The Highway Capacity Manual (HCM) employs a simple five-point system to assess the quality of bikeway pavement as part of the comprehensive bicycle level of service (LOS) evaluation. Unfortunately, the ambiguous and rudimentary nature of the existing HCM Pavement Quality Index (PQI) fails to offer an objective review of bikeways across different jurisdictions. In the following analysis, first is an assessment of the PQI and bicycle LOS in the HCM. To demonstrate the impact of the pavement quality rating and the importance of a more standardized evaluation method, a sensitivity analysis is performed. An improved PQI matrix is then proposed based on a comprehensive literature synthesis. The new matrix allows for a more holistic understanding of pavement quality in a three-category framework. The proposed methodology includes specifications for the functionality, structural integrity, and maintenance of bikeways. Within each category, objective thresholds are defined, such as for potholes, cracks, and maintenance routines, to minimize any potential subjectivity.
Examining Driver Compliance with a Move-Over/Slow Down Law in Consideration of Vehicle Type and Messages Displayed on Upstream Dynamic Message Signs
Authors: Megat-Johari Nusayba , Megat-Johari Megat-Usamah , Savolainen Peter , Gates Timothy , Kassens-Noor Eva
Published: July 2021

Move-over laws are intended to enhance the safety of road agency and law enforcement personnel who are working on or near the roadway. This study examined driver behavior through a series of field studies where these types of vehicles were located on the outside shoulder of a freeway with their lights activated. The study also evaluated the use of upstream dynamic message signs (DMS) to discern whether targeted safety messages had any impact on behavior under this scenario. Upstream and downstream speed and lane position data were collected from vehicles originally traveling in the rightmost lane upstream of the DMS and emergency/service vehicle at two locations in Michigan. Logistic regression models were estimated to assess driver compliance with the law while considering important contextual factors, such as the type of vehicle on the shoulder and the message displayed on the DMS. The results indicated that drivers were more likely to move over or reduce their speeds when a police car was located on the shoulder as compared to a transportation agency pickup truck. In general, the type of message displayed had minimal impact on driver behavior. The one exception showed that drivers were likely to drive at or below the speed limit when targeted move-over messages were shown as compared to standard travel time messages. For all message types, both speed and lane compliance improved if the roadside vehicle was a police car.
Quantitative Assessments of Crack Sealing Benefits by 3D Laser Technology
Authors: Yang Zhongyu , Zhang Xinyi , Tsai Yichang (James) , Wang Zhaohua
Published: July 2021

Crack sealing is one of the most commonly used methods to preserve asphalt pavements. However, quantification of crack sealing benefits (or the long-term delaying effects of crack sealing on crack propagation) remains unavailable because field crack lengths could not be measured accurately and efficiently. In this study, 3D laser technology is proposed to measure and compare the growth of crack lengths between sealed and non-sealed pavement sections and, for the first time, to accurately and efficiently quantify the crack sealing benefits. To validate the proposed method and find adequate treatment timing (or conditions), nine field sites in Georgia, U.S., with different pavement pre-treatment conditions and roadway environmental factors were monitored over 3 years from December 2016 to September 2019. The study results showed that crack sealing can retard crack growth by 40%–128%, and such delaying effects are more significant under better pavement pre-treatment conditions. The findings suggest that transportation agencies can prolong the service life of pavements by applying crack sealing before the pavement condition becomes poor. In addition, this work has been proved to be very valuable for transportation agencies to determine the best timing and treatment criteria for crack sealing.
Car-Following Described by Blending Data-Driven and Analytical Models: A Gaussian Process Regression Approach
Authors: Soldevila Ignasi Echaniz , Knoop Victor L. , Hoogendoorn Serge
Published: July 2021

Traffic engineers rely on microscopic traffic models to design, plan, and operate a wide range of traffic applications. Recently, large data sets, yet incomplete and from small space regions, are becoming available thanks to technology improvements and governmental efforts. With this study we aim to gain new empirical insights into longitudinal driving behavior and to formulate a model which can benefit from these new challenging data sources. This paper proposes an application of an existing formulation, Gaussian process regression (GPR), to describe individual longitudinal driving behavior of drivers. The method integrates a parametric and a non-parametric mathematical formulation. The model predicts individual driver’s acceleration given a set of variables. It uses the GPR to make predictions when there exists correlation between new input and the training data set. The data-driven model benefits from a large training data set to capture all driver longitudinal behavior, which would be difficult to fit in fixed parametric equation(s). The methodology allows us to train models with new variables without the need of altering the model formulation. And importantly, the model also uses existing traditional parametric car-following models to predict acceleration when no similar situations are found in the training data set. A case study using radar data in an urban environment shows that a hybrid model performs better than parametric model alone and suggests that traffic light status over time influences drivers’ acceleration. This methodology can help engineers to use large data sets and to find new variables to describe traffic behavior.
Open Science and Feminist Ethics: Promises and Challenges of Open Access
Authors: Brabeck Mary M.
Published: July 2021

Open science advocates argue that making data sets, studies, methodologies, and other aspects of research free from publication fees and available to scholars will increase collaborations, access, and dissemination of knowledge. In this article, I argue that open access policies and practices raise both feminist and ethical issues. I reflect on the five themes of feminist ethics identified 20 years ago by a task force of the Society for the Psychology of Women. I update the themes with recent scholarship of feminist philosophers and ethicists, and I use the themes to raise questions about the promises and challenges of open access. Throughout, I offer suggestions for all who seek to make knowledge of human psychology more complete and more accessible to more people. I conclude by offering recommendations informed by feminist ethics to those building the policies and practices of open access.

Incidence and Risk Factors of Acute Patellar Tendon Rupture, Repair Failure, and Return to Activity in the Active-Duty Military Population
Authors: Fredericks Donald R. , Slaven Sean E. , McCarthy Conor F. , Dingle Marvin E. , Brooks Daniel I. , Steelman Theodore J. , Donohue Michael A. , Griffin Daniel W. , Giuliani Jeffrey R. , Dickens Jonathan F.
Published: July 2021

Background:

Patellar tendon ruptures have a reported incidence of 0.68 per 100,000 person-years in the general population. The epidemiology of surgically treated patellar tendon ruptures in the US military has yet to be reported, which would provide opportunity for identification of risk factors for these otherwise healthy and active patients.

Purpose:

To determine the incidence of patellar tendon rupture in the Military Health System (MHS) population and to analyze demographic patterns, surgical fixation methods, and rerupture rates.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

We utilized the MHS Data Repository (MDR) to identity active-duty military servicemembers surgically treated for patellar tendon rupture between 2010 and 2015. Records were reviewed for demographic information, injury characteristics, fixation technique, and occurrence of rerupture. Risk factors for rupture were calculated using Poisson regression based on population counts and demographic data obtained in the MDR. Risk factors for rerupture and return to duty were analyzed via univariate analysis and multivariate regression.

Results:

A total of 504 operatively treated primary patellar tendon repairs in 483 patients were identified, with an overall incidence of 6 per 100,000 person-years. Mean age was 33.6 years (range, 17-54 years) and 98% of patients were male. Fixation method was 81% bone tunnels and 7% suture anchors, and 12% were unknown. Black race had a higher relative rate ratio for rupture compared with the race categories White (9.21; P < .0001) and Other (3.27; P < .0001). The rupture rate was higher in 35- to 44-year-old patients compared with those aged 18 to 24 years ( P < .0001), 25 to 34 years ( P < .0001), and 45 to 64 years ( P = .004). Return to full previous level of activity occurred in 75.8% of patients, 14.6% returned to activity with limitations, and 9.5% were medically separated. The rerupture rate was 3%. Fixation method, tobacco usage, body mass index, and race were not significant risk factors for rerupture.

Conclusion:

The incidence of patellar tendon rupture in the US military population is substantially higher than has been reported in the civilian population. Among military personnel, men, Black servicemembers, and those aged 35 to 44 years were at highest risk for patellar tendon rupture. Three-quarters of patients were able to return to full activity without limitations. The rerupture rate was low and unaffected by fixation method.
A Computed Tomography Angiography (CTA): Based score (SGPGI score) to predict level of difficulty, operative, and postoperative outcomes for right-sided radical nephrectomy
Authors: Singh Uday P , Madhavan Kumar , Yadav Priyank , Soni Rahul , Lal Hira , Sureka Sanjoy K , Kapoor Rakesh , Srivastava Aneesh
Published: July 2021

Objective:

With the advent of laparoscopic approach for the large (T1b–T3a ± N1) right renal masses, higher rates of complications and conversion to open surgery are being reported. The role of preoperative angioembolization (PAE), which has increased cost and inherent morbidity but may help in select circumstances has also not been clearly defined in the literature. We therefore devised a scoring system (SGPGI score) based on pre-operative Computed Tomography Angiography (CTA) to predict the level of difficulty of radical nephrectomy and enhance its safety and efficacy which could also be used for the judicious use of PAE in selected cases.

Methods:

In a prospective observational study on 52 patients with right renal masses from January 2014 to July 2018, we calculated a score based on CTA parameters. The patients were stratified for type and duration of surgery, blood loss, postoperative stay, and Clavien-Dindo grade of postoperative complications.

Results:

Patients were classified into three groups based on our scoring system. Progressively groups with higher score had higher blood loss, operating time, complications and hospital stay, and were more likely to have undergone conversion to open surgery (Area under curve 0.8625 for a cut off score of 10). Intraclass Correlation Coefficient (ICC) was 0.678–1 for the different components of our score.

Conclusion:

The pre-operative CTA based SGPGI score evaluates right renal masses and is able to predict intra-operative difficulties effectively, leading to enhancement of surgery safety and efficacy. It also helps judiciously use PAE.
Heroes and the many: Typological reflections on the collective appeal of the heroic. Revolutionary Iran and its implications
Authors: Gölz Olmo
Published: July 2021

The heroic figure is a human fiction of the wholly singular. In the hero, discourses about ideals and exemplariness, extra-ordinariness and exceptionalness, agonality, transgressivity, or good and evil become condensed into a single individual. Thus, the hero is the opposite of the masses. As it is argued in this article, the answer to the question of what distinguishes a hero lies in the supererogatory moment, the reference to the hero’s quality of more than can be expected: the heroic figure does more than he or she has to, more than duty requires of an ordinary person, and this is the reason they are heroized. However, this also points to a dialectic moment of the heroic in which the opposition between the hero and the many seems to be suspended. Following Niklas Luhmann, the hero represents the paradox of conformity through deviance, because through the example of their abnormality they produce in others a desire to imitate them. In the end, there is a collective appeal of the heroic that affects even the conceptual complement of the hero: the crowd which is characterized by the disappearance of the individual within it. Inspired by Luhmann’s sociological reflections on the heroic as well as Elias Canetti’s anthropological perspectives on the phenomena of the crowd, this article traces the rhetoric of the hero along its path from the singular to the plural. Against the backdrop of the analysis of the heroic in revolutionary Iran, a generalizable typology is proposed that distinguishes between the hero, the collective of heroes, the heroic collective, and collective heroism. This order reflects a progression that is analogous to the conjunction of the one and the many, moving qualitatively from the distinct figure of the hero to the indistinguishable masses.

This study has compared the news coverage of African American issues during the COVID-19 pandemic between general-interest online newspapers and Black news sites. Compared with COVID-19 pandemic news coverage by general-interest news sites, news coverage by Black news sites included significantly higher number of stories with African American issues. This study also identifies similarities in pandemic news coverage of African American issues between local news sites and Black news sites publishing from Black-majority cities.
The Relationship Between Social Support and Student Academic Involvement: The Mediating Role of School Belonging
Authors: Vargas-Madriz Luis Francisco , Konishi Chiaki
Published: July 2021

Canada’s high school graduation rates are still low when compared to other members of the OECD. Previous studies have found academic involvement is associated with positive trajectories toward graduation, that social support promotes student engagement, and that school belonging could mediate this relationship. Still, little is known about the specificity of such mediation, especially in Québec. Therefore, this study examined the role of belonging as mediator of the relationship between social support and academic involvement. Participants ( N = 238) were high-school students from the Greater Montréal Area. All variables were measured by the School-Climate Questionnaire. Results from hierarchical multiple regressions indicated parental support had a direct relationship, whereas peer and teacher support had a mediated relationship by school belonging with academic involvement. Results highlight the critical role of school belonging in promoting academic involvement in relation to social support.
Indigenous Planning: From Forced Assimilation to Self-determination
Authors: Hibbard Michael
Published: July 2021

Interest in Indigenous planning has blossomed in recent years, particularly as it relates to the Indigenous response to settler colonialism. Driven by land and resource hunger, settler states strove to extinguish Indigenous land rights and ultimately to destroy Indigenous cultures. However, Indigenous peoples have persisted. This article draws on the literature to examine the resistance of Indigenous peoples to settler colonialism, their resilience, and the resurgence of Indigenous planning as a vehicle for Indigenous peoples to determine their own fate and to enact their own conceptions of self-determination and self-governance.
Corruption, Campaigning, and Novelty: The 2020 Parliamentary Elections and the Evolving Patterns of Party Politics in Slovakia

Party politics across Central and Eastern Europe has become less structured. Many of the divides that anchored political competition have waned in recent years, weakening the attachment of voters to the existing palette of parties and making them more likely to be attracted to new and non-traditional electoral vehicles. But for such parties to succeed at the ballot box, they need to be able to frame elections and campaign effectively. Drawing on data from a specially commissioned survey, we find that the success of Ordinary People and Independent Personalities (OĽaNO) led by Igor Matovič in the 2020 parliamentary elections in Slovakia owed much to the crafting of an anti-corruption appeal combined with an effective campaign. Both mobilization and conversion of voters, particularly through television and the leaders’ debates, in the months leading up to election day ensured OĽaNO won a quarter of the vote. OĽaNO stands in stark contrast to other parties whose leaders failed to craft as effective a message, miscalculated the impact of electoral rules and in some cases were unable to distance themselves enough from their past actions. The success of OĽaNO underlines that themes related to anti-corruption and good governance have become central to party politics and political contestation. More broadly, the election and its aftermath continued a general trend of forward movement of voters from old parties to new to newer still, indicating the churn of party politics in Slovakia is likely to continue.

The use of artificial intelligence (AI) applications in government is receiving increasing attention from global research and practice communities. This article, introducing a Special Issue on Artificial Intelligence in Government published in the Social Science Computer Review, presents an overview of some of the main policy initiatives across the world in relation to AI in government and discusses the state of the art of existing research. Based on an analysis of current trends in research and practice, we highlight four areas to be the focus of future research on AI in government: governance of AI, trustworthy AI, impact assessment methodologies, and data governance.
Impact of STEM Sense of Belonging on Career Interest: The Role of STEM Attitudes
Authors: Xu Chao , Lastrapes Renée E.
Published: July 2021

Prior research has established a direct belonging–interest pathway among students underrepresented in science, technology, engineering, and mathematics (STEM) fields; however, evidence related to how a sense of belonging in STEM may operate to affect career interest remains limited. Drawing on data from 103 students (female: n = 70; male: n = 33) participating in grant activities at a Hispanic-serving institution, the present study seeks to address this gap by examining a model relating STEM sense of belonging, career interest, and STEM attitudes. Results of multigroup analysis revealed that, whereas female students’ STEM sense of belonging had an indirect impact on their career interest via its correlation with STEM attitudes, the impact of male students’ STEM sense of belonging on their career interest was both direct and indirect. Implications of the findings for educational and counseling practices on supporting women in STEM are discussed, along with future research directions.
Analysis of the influence of power coupling type and transmission type of the powertrain on the performance of single-motor hybrid electric vehicles
Authors: Peng Hang , Qin Datong , Hu Jianjun , Chen Zhipeng
Published: July 2021

Existing research on parallel hybrid electric vehicles (HEV) mainly focuses on optimizing the component sizes and control strategies of the single-motor parallel hybrid electric powertrain (SMPHP), and less analyzes the influence of powertrain configuration on the performance of the vehicle. Therefore, the influence of the power coupling type and transmission type of the powertrain configuration on the fuel economy and drivability performance of parallel HEVs is studied in this paper. Considering three types of powertrain topologies (P2 torque-coupled, P2 dual-mode coupled and P3 torque-coupled) and two types of automatic transmissions (DCT and CVT), six typical types of SMPHP configurations to be discussed are determined. To obtain their optimal fuel economy and drivability performance, a multi-objective optimization and analysis method based on dynamic programming and multi-objective particle swarm optimization algorithm is proposed to optimize the component sizes and control variables of powertrain configurations. Finally, the optimal performance and component size optimization results of six typical SMPHP configurations are analyzed and compared, and the influence of powertrain configuration on the performance and components sizing of the SMPHP is obtained, which contributes to the configuration design of the parallel hybrid electric powertrain.

Vehicle detection in severe weather has always been a difficult task in the environmental perception of intelligent vehicles. This paper proposes a vehicle detection method based on pseudo-visual search and the histogram of oriented gradients (HOG)–local binary pattern (LBP) feature fusion. Using radar detection information, this method can directly extract the region of interest (ROI) of vehicles from infrared images by imitating human vision. Unlike traditional methods, the pseudo-visual search mechanism is independent of complex image processing and environmental interferences, thereby significantly improving the speed and accuracy of ROI extraction. More notably, the ROI extraction process based on pseudo-visual search can reduce image processing by 40%–80%, with an ROI extraction time of only 4 ms, which is far lower than the traditional algorithms. In addition, we used the HOG–LBP fusion feature to train the vehicle classifier, which improves the extraction ability of local and global features of vehicles. The HOG–LBP fusion feature can improve vehicle detection accuracy by 6%–9%, compared to a single feature. Experimental results show that the accuracy of vehicle detection is 92.7%, and the detection speed is 31 fps, which validates the feasibility of the proposed method and effectively improve the vehicle detection performance in severe weather
