Normative Ecologies of Planning: Understanding Norms in Action
Authors: Lieto Laura
Published: June 2021

The paper deals with planning norms in action, assuming that planning regulation is one among many kinds of regulation with which planners must contend. Norms operate and co-evolve within a normative ecology where institutions collaborate and compete through overlapping and often incommensurate normative frameworks and rules of the game. The importance of socio-materiality in how different regulations work in practice is emphasized. To develop the normative ecology argument, a case study is presented on the effects of Airbnb tourism on the historic center of Napoli in southern Italy.

Purpose:

Targeted temperature management (TTM) is a standard of care in patients after cardiac arrest for neuroprotection. Currently, the effectiveness and efficacy of TTM after extracorporeal cardiopulmonary resuscitation (ECPR) is unknown. We aimed to compare neurological and survival outcomes between TTM vs non-TTM in patients undergoing ECPR for refractory cardiac arrest.

Methods:

We searched PubMed and 5 other databases for randomized controlled trials and observational studies reporting neurological outcomes or survival in adult patients undergoing ECPR with or without TTM. Good neurological outcome was defined as cerebral performance category <3. Two independent reviewers extracted the data. Random-effects meta-analyses were used to pool data.

Results:

We included 35 studies (n = 2,643) with the median age of 56 years (interquartile range [IQR]: 52-59). The median time from collapse to ECMO cannulation was 58 minutes (IQR: 49-82) and the median ECMO duration was 3 days (IQR: 2.0-4.1). Of 2,643, 1,329 (50.3%) patients received TTM and 1,314 (49.7%) did not. There was no difference in the frequency of good neurological outcome at any time between TTM (29%, 95% confidence interval [CI]: 23%-36%) vs. without TTM (19%, 95% CI: 9%-31%) in patients with ECPR ( P = 0.09). Similarly, there was no difference in overall survival between patients with TTM (30%, 95% CI: 22%-39%) vs. without TTM (24%, 95% CI: 14%-34%) ( P = 0.31). A cumulative meta-analysis by publication year showed improved neurological and survival outcomes over time.

Conclusions:

Among ECPR patients, survival and neurological outcome were not different between those with TTM vs. without TTM. Our study suggests that neurological and survival outcome are improving over time as ECPR therapy is more widely used. Our results were limited by the heterogeneity of included studies and further research with granular temperature data is necessary to assess the benefit and risk of TTM in ECPR population.

The Offense-Specific Nature of Gender and Familial Responsibility in United States Federal Sentencing, 2010–2016
Authors: Holmes Bryan , D’Amato Christopher , Holmes Stephen T.
Published: June 2021

Prior sentencing research has identified leniency afforded to females (compared with males) and those with familial responsibility (compared with those without). Studies have also found that the effect of defendant gender, familial responsibility, and their intersections depend on the type of offense examined. What remains unclear is the situations in which these factors matter more or less. The purpose of this study is to disaggregate extralegal effects by understanding how gender, familial responsibility, and their intersections influence federal sentencing outcomes across various offense types. Findings from this study suggest that gender, familial responsibility, and their combinations exert different influences depending on the (a) dependent variable and (b) offense type examined.

Published: June 2021

Coronavirus has had a significant impact on daily life. Prisons are not exempt from the impact of coronavirus disease 2019 (COVID-19). Prisons are particularly at risk due to their secure environment and vulnerable inmate populations. We examine steps taken by the 50 state departments of correction and the Federal Bureau of Prisons to mitigate COVID-19 as reported on their websites. While states vary in their response to the virus, those responses do not appear to be related to regional or political differences. Few are testing or quarantining all inmates, and there are more proactive responses devoted to staff than inmates in their facilities. Findings demonstrate that prison systems’ policies regarding COVID-19 testing, quarantining, and provision of personal protective equipment for inmates do not fully align with Centers for Disease Control and Prevention recommendations. As a result, the steps prison systems are taking to mitigate the effect of COVID-19 may be more reactionary than proactive, which may be less effective overall.
Idiographic personality coherence: A quasi experimental longitudinal ESM study
Authors: Beck Emorie D , Jackson Joshua J
Published: June 2021

Personality is a study of persons. However, persons exist within contexts, and personality coherence emerges from persons in contexts. But persons and environments bidirectionally influence each other, with persons selecting into and modifying their contexts, which also have lasting influences on personality. Thus, environmental change should produce changes in personality. Alternatively, environmental changes may produce few changes. This paradoxical viewpoint is based on the idea that novel environments have no predefined appropriate way to behave, which allows preexisting personality systems to stay coherent. We test these two perspectives by examining longitudinal consistency idiographic personality coherence using a quasi-experimental design (N = 50; total assessments = 5093). Personality coherence was assessed up to one year before the COVID-19 pandemic and again during lockdown. We also test antecedents and consequences of consistency, examining both what prospectively predicts consistency and what consistency prospectively predicts. Overall, consistency was modest but there were strong individual differences, indicating some people were quite consistent despite environmental upheaval. Moreover, there were relatively few antecedents and consequences of consistency, with the exception of some goals and domains of satisfaction predicting consistency, leaving open the question of why changes in coherence occur.

Published: June 2021

This study mapped the personality and genetics of risky excitement-seekers focusing on skydiving behavior. We compared 298 skydivers to 298 demographically matched controls across the NEO Personality Inventory-3 domains, facets, and 240 items. The most significant item-level effects were aggregated into a poly-item score of skydiving-associated personality markers (Study 1), where higher scores describe individuals who enjoy risky situations but have no self-control issues. The skydiving-associated personality marker score was associated with greater physical activity, higher rate of traumatic injuries, and better mental health in a sample of 3558 adults (Study 2). From genetic perspective, we associated skydiving behavior with 19 candidate variants that have previously been linked to excitement-seeking (Study 1). Polymorphisms in the SERT gene were the strongest predictors of skydiving, but the false discovery rate-adjusted (FDR-adjusted) p-values were non-significant. In Study 2, we predicted the skydiving-associated personality marker score and E5: Excitement-seeking from multiple risk-taking polygenic scores, using publicly available summary data from genome-wide association studies. While E5: Excitement-seeking was most strongly predicted by general risk tolerance and risky behaviors’ polygenic scores, the skydiving-associated personality marker score was most strongly associated with the adventurousness polygenic scores. Phenotypic and polygenic scores associations suggest that skydiving is a specific—perhaps more functional—form of excitement-seeking, which may nevertheless lead to physical injuries.

Authors: Wyman-Chick Kathryn A. , O’Keefe Lauren R. , Weintraub Daniel , Armstrong Melissa J. , Rosenbloom Michael , Martin Phillip K. , Barclay Terry R. , Barrett Matthew J.
Published: June 2021

Background:

Research criteria for prodromal dementia with Lewy bodies (DLB) were published in 2020, but little is known regarding prodromal DLB in clinical settings.

Methods:

We identified non-demented participants without neurodegenerative disease from the National Alzheimer’s Coordinating Center Uniform Data Set who converted to DLB at a subsequent visit. Prevalence of neuropsychiatric and motor symptoms were examined up to 5 years prior to DLB diagnosis.

Results:

The sample included 116 participants clinically diagnosed with DLB and 348 age and sex-matched (1:3) Healthy Controls. Motor slowing was present in approximately 70% of participants 3 years prior to DLB diagnosis. In the prodromal phase, 50% of DLB participants demonstrated gait disorder, 70% had rigidity, 20% endorsed visual hallucinations, and over 50% of participants endorsed REM sleep behavior disorder. Apathy, depression, and anxiety were common prodromal neuropsychiatric symptoms. The presence of 1+ core clinical features of DLB in combination with apathy, depression, or anxiety resulted in the greatest AUC (0.815; 95% CI: 0.767, 0.865) for distinguishing HC from prodromal DLB 1 year prior to diagnosis. The presence of 2+ core clinical features was also accurate in differentiating between groups (AUC = 0.806; 95% CI: 0.756, 0.855).

Conclusion:

A wide range of motor, neuropsychiatric and other core clinical symptoms are common in prodromal DLB. A combination of core clinical features, neuropsychiatric symptoms and cognitive impairment can accurately differentiate DLB from normal aging prior to dementia onset.
Impact of peritoneal dialysis-related peritonitis on PD discontinuation and mortality: A population-based national cohort study

Published: June 2021

Background:

The impact of peritoneal dialysis-associated peritonitis (PD peritonitis) on long-term outcomes is uncertain. This nationwide retrospective study was conducted in Taiwan to understand the incidence, risk factors and long-term outcomes of PD peritonitis.

Methods:

A total of 11,202 incident adult peritoneal dialysis (PD) patients from 2000 to 2010 were collected from a Longitudinal Health Insurance Database and followed up until the end of 2011. Definition of peritonitis, the primary outcome, simultaneously met the diagnosis of peritonitis (International Classification of Diseases, Ninth Revision, Clinical Modification 567) and antibiotic use. Secondary outcomes included the impact of peritonitis on PD discontinuation and survival. Cox proportional hazards models with and without time-dependent variables were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).

Results:

There were 7634 peritonitis episodes in 4245 patients during the follow-up period. The overall incidence of peritonitis was 0.18 episodes per patient-year. Peritonitis-associated risk factors included older age, female gender, chronic heart failure, cerebrovascular disease, liver cirrhosis and lower monthly income. In an adjusted Cox hazard proportional regression with the time-dependent model, peritonitis patients had a higher risk of PD discontinuation (HR 2.71, 95% CI 2.52–2.92) and mortality (HR 1.68, 95% CI 1.57–1.81) compared to patients without peritonitis. The adjusted HRs for mortality increased with each prior episode: one episode, two episodes and more than two episodes (all p < 0.05). The adjusted HRs for PD discontinuation also increased with the frequency of peritonitis. These negative effects were greatest during the first year and persisted significantly after 5 years. In a sensitivity analysis in which peritonitis within 30 days of death or PD discontinuation was excluded, peritonitis patients still had significantly increased risk of PD discontinuation and mortality compared to patients without peritonitis.

Conclusions:

Although peritonitis incidence was low, our findings reveal that peritonitis carried acute and long-term sequelae of higher PD discontinuation and lower patient survival.
Non-Spousal Support, Marital Status, and Mortality Risk
Authors: Roth Adam R. , Peng Siyun
Published: June 2021

Objective

To investigate whether the association between non-spousal support and mortality risk differs by marital status.

Methods

Using data from the National Social Life, Health, and Aging Project (N = 2460), we estimate a series of logistic regression models to assess how non-spousal support moderates the relationship between marital status and mortality across a 5-year period.

Results

Never married respondents who had minimal perceived access to non-spousal support had a greater probability of death compared to married respondents with similar levels of non-spousal support. The disparity in mortality risk between these two groups disappeared when non-spousal support was high.

Discussion

Although family and friends play an important role in mortality risk in later life, these findings suggest that never married older adults exhibit a heightened dependence on support from non-spousal sources. Future research and policies should explore ways in which never married older adults can be integrated into a supportive social environment.
What are Governmental Human Rights Focal Points?
Authors: Lorion Sébastien , Lagoutte Stéphanie
Published: June 2021

This Special Issue aims at raising understanding of governmental human rights focal points (GHRFPs). It forms part of a renewed attention to the importance of domestic-level institutions within the international human rights regime. GHRFPs have emerged as a key recommendation of UN bodies, and a defined trend in setting up such State structures is observed in practice. Addressing GHRFPs as a single field of inquiry, this introductory article presents a common analytical approach, which makes it possible to analyse various forms of GHRFPs, with a view to generalising findings and enriching each type of GHRFP with the experiences and lessons learned of others. Hereby, the Special Issue consolidates and structures a research agenda on GHRFPs around key attributes identified in a preliminary manner, in order to spark some critical and constructive analysis of this specific manifestation of the domestic institutionalisation of human rights.
Towards a framework for integrating place-based approaches in entrepreneurship education
Authors: Larty Joanne
Published: June 2021

Regional and institutional contexts have been acknowledged as important to the design of entrepreneurship education (EE), yet the importance of place for entrepreneurship has so far received less attention. There is still much work to do in connecting students to places and engaging them in understanding the relationship between entrepreneurship, local communities and local economies within the EE curriculum. Taking inspiration from the notions of place-based and place-conscious learning, the paper proposes a framework for place-based EE and considers challenges for integrating place-based approaches into the EE curriculum. A case study of place-based EE at a university business school is then used to illustrate how the framework can be used to review existing curricula, as well as to reveal how an institution’s context might both facilitate and constrain opportunities for place-based learning. The paper provides a contribution by making more visible the important yet often invisible role of place in EE, while being mindful of the needs, resources and educational aims of regions and institutions.
Aircraft engine hot-section virtual sensor creation and gas path performance monitoring
Authors: Lu Feng , Jin Peng , Huang Jinquan , Wang Chen , Qin Haiqin
Published: June 2021

Various Kalman filter approaches have been presented for performance estimation of aircraft engines provided that sensor measurement numbers are sufficient and all of them are available. However, it is difficult to collect all physical parameters along the gas path since the complex structure limits sensor installation, especially around the high-pressure turbine. The contribution of this article is to create a virtual sensor in the hot-section based on the component physical characteristics and aerothermodynamic theory and develop a dual hypothesis test strategy combined with a state estimator to track abrupt degradation of the engine component. A novel couple algorithm of the unscented Kalman filter using a virtual sensor is developed that has three primary advantages: (i) The performance degradation of four rotatory components can be estimated without sensor P43. (ii) The accuracy of state estimation using the virtual sensor is equivalent to that of sensor P43, and it adapts to the abrupt change of engine operating condition in the whole flight envelope. (iii) If the sensor can be installed in the future, it can be engaged to its analytical redundancy. Simulations are carried out on typical abrupt degradation datasets of aircraft engines, which demonstrate the superiority of anomaly detection of gas path component performance using virtual sensor measurements, especially hot-section components.

Maintaining a stable gait requires a dynamic balance control, that can be altered in persons with Multiple Sclerosis (MS), Stroke (ST), and Parkinson’s disease (PD). The understanding of the strategy for Center of Mass (CoM) positioning adopted by patients during walking is important to be able to program treatments aimed at improving gait control and preventing falls. Forty-four persons with a mild-to-moderate neurological disorder (20 with MS, 14 with ST, 10 with PD) underwent clinical examination and gait analysis. Ten Healthy Subjects (HS) walking at matched speed provided the normative data. Dynamic balance was assessed using the margin of stability (MoS). It was calculated as the distance between the extrapolated Center of Pressure and the extrapolated CoM at mid-stance. The MoS values for lower limbs were calculated in patients and compared with speed-matched values of HS. Persons with neurological disorder showed increased MoS in the medio-lateral direction with respect to HS. Within-group comparison analysis showed a symmetry between lower limbs in HS (Mean (95%CI) [mm], dominant vs non-dominant limb, 43.3 (31.9–54.6) vs 42.9 (28.8–56.9)) and PD (less affected vs more affected limb, 71.1 (59.8–82.5) vs 72.5 (58.5–86.6)), while a significant asymmetry was found in MS (54.4 (46.4–62.4) vs 81.1 (71.2–91.1)) and ST (52.1 (42.6–61.7) vs 74.7 (62.8–86.6)) participants. The history of falls was comparable among PD, MS, and ST groups, and the MoS in the frontal plane showed a strong correlation with these records. Objective assessment of MoS revealed pathology-specific strategies showing different impacts in MS, ST, and PD on the ability to control CoM information to manage the balance between limbs during gait. MoS evaluation will provide useful information to address a tailored rehabilitation program and to monitor disease progression.
Design and implementation of decoupled periodic control scheme for a laboratory-based quadruple-tank process
Authors: Pradhan Jatin K , Ghosh Arun
Published: June 2021

It is well known that linear time-invariant controllers fail to provide desired robustness margins (e.g. gain margin, phase margin) for plants with non-minimum phase zeros. Attempts have been made in literature to alleviate this problem using high-frequency periodic controllers. But because of high frequency in nature, real-time implementation of these controllers is very challenging. In fact, no practical applications of such controllers for multivariable plants have been reported in literature till date. This article considers a laboratory-based, two-input–two-output, quadruple-tank process with a non-minimum phase zero for real-time implementation of the above periodic controller. To design the controller, first, a minimal pre-compensator is used to decouple the plant in open loop. Then the resulting single-input–single-output units are compensated using periodic controllers. It is shown through simulations and real-time experiments that owing to arbitrary loop-zero placement capability of periodic controllers, the above decoupled periodic control scheme provides much improved robustness against multi-channel output gain variations as compared to its linear time-invariant counterpart. It is also shown that in spite of this improved robustness, the nominal performances such as tracking and disturbance attenuation remain almost the same. A comparison with [Formula: see text]-linear time-invariant controllers is also carried out to show superiority of the proposed scheme.

Published: June 2021

As an ecotone, the region between the Amazon Rainforest and Tropical Savanna (Cerrado) biomes is, by definition, more susceptible to climate change. Therefore, understanding palaeoenvironmental dynamics is essential to address the future responses of such transition areas to climatic fluctuations. In this context, we present a new sediment record for the Late-Holocene retrieved from Barro-Preto, currently an oxbow lake located in an ecotone at the southern Brazilian Amazon border. Our multi-proxy data include carbon and nitrogen isotopes, as well as bulk TOC, chlorophyll derivatives, grain-size and microcharcoal analyses, all anchored on a radiocarbon-dated chronology. The sedimentary process recorded at the Barro-Preto Lake responded to both local and regional climate dynamics. It was influenced by river excursions associated to local responses to precipitation changes by the activation of the palaeochannel connecting the main-stem river and the Barro-Preto lake. This activation was evidenced by the presence of different colour lithology laminations accompanied by coarser sediments and also by climate conditions known to influence the Amazon region. Depositional processes linked to lake dynamics and different oxbow lake cycle stages were also important to explain the changes verified in the Barro-Preto record, endorsing the use of this lake formation for palaeoclimatic reconstructions. The record indicated a rising humidity trend, reflected by a progressive increase in lacustrine productivity, in accordance to other studies carried out in the Amazon region concerning the Late-Holocene, associated with a more southward displacement of the Intertropical Convergence Zone. Despite this rising humidity trend, dry episodic events during the Late-Holocene were evidenced by charcoal data, also coherent with regional Amazon studies, albeit exhibiting increased intensity, suggesting that the transitional nature of the environment might have influenced susceptibility to fires.

Published: June 2021

Previously, we developed a Bio3D conduit fabricated from human fibroblasts and reported a significantly better outcome compared with artificial nerve conduit in the treatment of rat sciatic nerve defect. The purpose of this study is to investigate the long-term safety and nerve regeneration of Bio3D conduit compared with treatments using artificial nerve conduit and autologous nerve transplantation.

We used 15 immunodeficient rats and randomly divided them into three groups treated with Bio3D ( n = 5) conduit, silicon tube ( n = 5), and autologous nerve transplantation ( n = 5). We developed Bio3D conduits composed of human fibroblasts and bridged the 5 mm nerve gap created in the rat sciatic nerve. The same procedures were performed to bridge the 5 mm gap with a silicon tube. In the autologous nerve group, we removed the 5 mm sciatic nerve segment and transplanted it. We evaluated the nerve regeneration 24 weeks after surgery.

Toe dragging was significantly better in the Bio3D group (0.20 ± 0.28) than in the silicon group (0.6 ± 0.24). The wet muscle weight ratios of the tibial anterior muscle of the Bio3D group (79.85% ± 5.47%) and the autologous nerve group (81.74% ± 2.83%) were significantly higher than that of the silicon group (66.99% ± 3.51%). The number of myelinated axons and mean myelinated axon diameter was significantly higher in the Bio3D group (14708 ± 302 and 5.52 ± 0.44 μm) and the autologous nerve group (14927 ± 5089 and 6.04 ± 0.85 μm) than the silicon group (7429 ± 1465 and 4.36 ± 0.21 μm). No tumors were observed in any of the rats in the Bio3D group at 24 weeks after surgery.

The Bio3D group showed significantly better nerve regeneration and there was no significant difference between the Bio3D group and the nerve autograft group in all endpoints.
Effect of surface modification on mechanical properties of filature silk waste and nanoclay filler-based polymer matrix composite
Authors: Nair Rahul , Bhattacharya Abhishek , Bhowmik Papiya , Kant Ravi
Published: June 2021

Natural fibers have been attracting researchers and engineers as an alternative reinforcement of synthetic fibers in polymer composites due to their low cost, availability from natural resources, satisfactory high modulus and tensile strength, and biodegradability. Filature silk waste (FSW) is the remnant part of the cocoons which is produced during the silk forming process. The current study focuses on the comparison of tensile properties between untreated filature silk waste reinforced epoxy-based composite (UTFSWREC), 2 wt% alkali-treated filature silk waste reinforced epoxy-based composites (TFSWREC) and 2 wt% alkali-treated filature silk waste reinforced epoxy nanocomposites (TFSWRENC). The tensile properties showed that Young’s modulus of composites increases with surface modification of fiber and further enhances with nanoclay filler. TFSWREC and TFSWRENC displayed a higher tensile modulus than UTFSWREC. Scanning Electron Microscopy (SEM) showed the removal of the sericin layer from the surface of fiber, which resulted in the separation of fibrils and further resulted in the enhancement of the mechanical properties. FTIR analysis confirmed that intermolecular bonding improves with the chemical treatment and further refined with nanoclay filler addition.
Nurses’ self-assessed moral courage and related socio-demographic factors
Authors: Hauhio Nora , Leino-Kilpi Helena , Katajisto Jouko , Numminen Olivia
Published: June 2021

Background:

Nurses need moral courage to ensure ethically good care. Moral courage is an individual characteristic and therefore it is relevant to examine its association with nurses’ socio-demographic factors.

Objective:

To describe nurses’ self-assessed level of moral courage and its association with their socio-demographic factors.

Research design:

Quantitative descriptive cross-sectional study. The data were collected with Nurses’ Moral Courage Scale and analyzed statistically.

Participants and research context:

A total of 482 registered nurses from a major university hospital in Southern Finland completed the Finnish language version of Nurses’ Moral Courage Scale in autumn 2017.

Ethical considerations:

Ethical approval was obtained from the university ethics committee and permission for the data collection from the participating hospital. Ethical principles and scientific guidelines were followed throughout the research process.

Findings:

Nurses’ self-assessed level of moral courage was rather high. On Visual Analogy Scale (0–10), the mean value was 8.20 and the mean score of the four dimensional, 21-item Nurses’ Moral Courage Scale was 4.09 on a 5-point Likert-type scale. Respondents’ gender, present work role, ethical knowledge base, additional ethics education, self-study as a means to acquire ethical knowledge, and frequency of work situations needing moral courage were statistically significantly associated with nurses’ moral courage.

Discussion:

Strongest association was found between nurses’ higher moral courage level and formal and informal ethics education. Honesty and patient’s humane and dignified encounter received the highest scores indicating respondents’ internalization of the core values of nursing.

Conclusion:

Although nurses were fairly morally courageous, moral courage should be a part of nurses’ basic and continuing education thus covering its theoretical and practical learning. Since moral courage is a virtue that can be taught, learnt, and practiced, education is a relevant way to maintain and further strengthen nurses’ moral courage.
Living with Barren Truths: A Tale of Triumphalism and Tribulations of a Technology
Authors: Mohanty Sital , Sahoo Subhasis , Swain Pranay Kumar
Published: June 2021

Science, technology and human values have been the subject of enquiry in the last few years for social scientists and eventually the relationship between science and gender is the subject of an ongoing debate. This is due to the event of globalization which led to the exponential growth of new technologies like assisted reproductive technology (ART). ART, one of the most iconic technological innovations of the twentieth century, has become increasingly a normal social fact of life. Since ART invades multiple human discourses—thereby transforming culture, society and politics—it is important what is sociological about ART as well as what is biological. This article argues in commendation of sociology of technology, which is alert to its democratic potential but does not concurrently conceal the historical and continuing role of technology in legitimizing gender discrimination. The article draws the empirical insights from local articulations (i.e., Odisha state in eastern India) for the understandings of motherhood, freedom and choice, reproductive right and rights over the body to which ART has contributed. Sociologically, the article has been supplemented within the broader perspectives of determinism, compatibilism alongside feminism.
Global Green New Deal: A Global South perspective
Authors: Chen Ying , Li An
Published: June 2021

Most proposed solutions in the Global Green New Deal literature involve finance and technology transfers to address the imbalance between the Global North and Global South, while providing little discussion of the internal socioeconomic structures within countries in the Global South. This article uses China as a case study to show that without addressing the issue of domestic informality, the potential benefits of a Global Green New Deal are less likely to be fully realised in the Global South. We use the Input-Output method and our originally constructed data on formal and informal employment to calculate the informal employment share in two exemplary renewable energy sectors: solar and wind. We find that more than half of the jobs created in the solar and wind energy sectors, with a given level of spending, will be in the informal economy, and hence are associated with low wages and little social welfare protection. The results imply that, without addressing informality, both renewable energy sectors perpetuate the informal structure in the broader economy. We also question the capitalist nature of ‘green jobs’ created by the Green New Deal. Based on the results, we call for a more organic integration of a Global South perspective in the studies of a Global Green New Deal.

Transformative Design Pedagogy: Teaching Biophilic Design Through Experiential Learning
Authors: Ebbini Genell W.
Published: June 2021

Background: Biophilia is becoming an important theme in contemporary design practice. Research in this area has demonstrated measurable improvements in human health and wellbeing when built environments are able to connect people to nature. However, there is much debate about how design students can best learn to fluidly implement biophilic principles in their work. Purpose: This article describes an action research study conducted by design educators to evaluate experiential learning techniques in health care–focused interior design studio courses. The goal was to improve students’ creative synthesis in applying biophilic principles. Methodology/Approach: The author followed the four steps of action research—planning, action, observation, and reflection—in developing and evaluating a new experiential learning framework. An observational approach was used to assess student projects and the effectiveness of these teaching methods. Findings/Conclusions: Students who participated in the experiential learning activities demonstrated a relatively higher degree of holistic integration of biophilic principles in their design projects. Implications: While the observational findings are provisional evidence, these results provide insights into the advantages that experiential pedagogies may have in helping students to integrate and apply design knowledge. The ability to connect biophilic design principles to direct personal experiences appears to enhance creative synthesis in student work.

Authors: Yoo Hyesoo , Kang Sangmi
Published: June 2021

The purpose of this study was to examine how preservice music teachers navigate 21st-century skills in their lesson planning and field experiences. Among the various skills, we focused on the Partnership for 21st Century learning and innovation skills. Over 8 weeks, 10 preservice music teachers designed lesson plans focused on creativity, critical thinking, communication, and collaboration, and peer taught their lessons in an elementary music methods class as well as in their field placements. Our data sources included participants’ post-field teaching self-evaluations and post-project reflective essays, as well as instructor and supervisor field notes and face-to-face participant interviews. Through the data analysis, we identified three central concepts: (a) Curriculum-as-lived: Teaching like improvising, (b) Balanced in-betweenness: Structure and freedom, and (c) Collective efforts: Stepping away from comfort zones.

Conventional methods are not suitable for difficult to treat osteochondral lesions of the talus (OCLTs). The role of particulated juvenile allograft articular cartilage implantation is not well elucidated for long-term patient outcomes.

Methods:

Thirteen patients with difficult-to-treat OCLTs underwent arthroscopy-assisted implantation of particulated juvenile articular cartilage graft into defects from 2010 to 2012 by the same surgeon. “Difficult to treat” was defined as having at least 3 of the following features or 2 if both variables described lesion characteristics: (1) lesions size of 107 mm2 or greater, (2) shoulder lesions, (3) patients who failed microfracture, (4) patient aged ≥40 years, or (5) patient body mass index (BMI) >25. Patients were evaluated using physical examination, patient interviews, and outcome score measures. Patients had follow-up at 2 years, 4 years, and between 6 and 10 years at their most recent follow-up. Differences in functional outcome scores were compared before and after surgery.

Results:

Patients (age: 46.5 ± 11.8 years, BMI: 28.5 ± 6.1) had, on average, most recent follow-up of 8.0 years (range 72-113 months). Average visual analog scale for pain score decreased for patients by 3.9 points (95% confidence interval [CI] 2.18-5.60), when compared to preoperative assessment. Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscale scores also improved from 46.5 to 80.9 (95% CI 21.35-47.43), and from 18.8 to 57.9 (95% CI 21.05-57.10), respectively. Short Form–36 Health Survey physical component scores showed significant improvement by an average of 45.5 points (95% CI 32.42-58.50). American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Scale scores improved from 55.2 to 80.3 (95% CI 12.459-37.741).

Conclusion:

These results demonstrate positive patient-reported long-term outcomes for a cohort of patients with difficult OCLTs, followed over the course of 6-10 years after treatment with arthroscopy-assisted particulated juvenile articular cartilage implantation.

Authors: Emami Razavi Seyede Zahra , Azadvari Mohaddeseh , Fateh Hamid R. , Ghahvechi Akbari Masood , Kazemi Shahrbanoo , Rezaee Elahe
Published: June 2021

Background:

Multiple considerations should be taken before standardizing a clinical procedure such as efficacy, safety, or the cost. The aim of this study was to compare the effects of landmark-guided vs ultrasonography-guided intra-articular injection of corticosteroid into the first metatarsophalangeal joint cavity to reduce pain and dysfunction in patients with hallux rigidus.

Methods:

We carried out a single-blind randomized controlled trial with 2 parallel arms in an outpatient clinic affiliated with a medical university. In total, 50 participants (35 women) with the mean (SD) age of 49.8 (10.3) years were randomly allocated to landmark-guided or ultrasonography-guided groups (each n = 25). Each patient received a single intra-articular injection of 40-mg methylprednisolone plus 1 mL lidocaine into the affected first metatarsophalangeal joint. The primary outcome was joint pain and the secondary outcome was the American Orthopaedic Foot & Ankle Society score. We measured the outcomes at baseline and 2 and 6 weeks after the intervention.

Results:

Six weeks after the injections, there were no statistically significant differences between the study groups in pain reduction and increase in the American Orthopaedic Foot & Ankle Society scores ( P = .131 and .241, respectively). We did not find any complications for the injections in both groups. There were statistically significant changes within each group in pain and the scores for the landmark ( P < .001, and P = .007), and ultrasonography groups (both P < .001).

Conclusion:

Landmark guidance is as effective as ultrasonographic guidance for intra-articular injection in patients with hallux rigidus. A single intra-articular injection of 40 mg methylprednisolone plus 1 mL lidocaine is an efficient and safe therapeutic measure for decreasing joint pain and maintaining its function, at least for 6 weeks.

Published: June 2021

Background:

Quantifying first ray mobility is crucial to understand aberrant foot biomechanics. A novel device (MAP1st) that can perform measurements of first ray mobility in different weightbearing conditions, foot alignments, and normalization was tested. The reliability of these measurement techniques was assessed in comparison to a handheld ruler considered representative of the common clinical examination.

Methods:

The study included 25 participants (50 feet). Two independent raters performed baseline, test-retest, and remove-replace measurements of first ray mobility with MAP1st and the handheld device. The effects of non-, partial, and full weightbearing in subtalar joint neutral and the resting calcaneal stance position were assessed. Measurement normalization relative to foot size was also investigated. Intra- and interclass correlation coefficients (ICCs) were calculated for each device between the 2 raters. In addition, Bland-Altman plots were constructed to determine if fixed biases or substantial outliers were present.

Results:

Similar intrarater ICC values were found for both devices (≥0.85). However, interrater ICC values were substantially improved by MAP1st compared with the handheld device (0.58 vs 0.06). Bland-Altman plots demonstrated biases of 1.27 mm for the handheld ruler, and 2.88 to 0.05 mm and −1.16 to 0.00 for linear and normalized MAP1st measurements, respectively. Improved reliability was achieved with MAP1st for normalized assessments of first ray mobility while the foot was placed in partial- and full-weightbearing resting calcaneal stance positions.

Conclusion:

MAP1st provided reliable assessments of partial- and full-weightbearing first ray mobility. It should help investigators to explore the potential relationships between first ray function and aberrant foot biomechanics in future research.

The dynamic analysis and vibration control of a kind of damping boring bar system with magnetorheological fluid absorber are studied. A two-degree-of-freedom dynamic model of boring bar with magnetorheological fluid dynamic vibration absorber is established, in which the magnetorheological fluid damper adopts the fractional-order Bingham model. The forced vibration of the system is studied, and the approximate analytical solution is obtained by the averaging method. By comparing the analytical solution with the numerical solution, the accuracy of the analytical solution is proved by their high degree of fit. And the parameters of boring bar system are optimized by using the analytical solution. To reduce the amplitude of the system, a semi-active control strategy of modified relative velocity method is used to suppress the resonance response of the boring bar. Under the semi-active relative velocity control, the approximate analytical solution of the system is also obtained by means of averaging method. The stability of the system under semi-active control is analyzed by using the Lyapunov method. Compared with passive control, the semi-active relative velocity control has a very great effect on the vibration amplitude suppression. The results can provide a reference for the study of dynamics and vibration control of the systems with magnetorheological fluid control.
Vibration of a cryomodule’s coupler during road transportation: Multibody analysis and experimental validation

The road transportation of critical components for cryogenic cryomodules is a challenging task. Indeed, the shipping and the handling of fundamental sub-assemblies can expose these components to harmful dynamic loads that can jeopardize their structural integrity. This article has the purpose of developing a finite element multibody model capable of assessing the acceleration on a test coupler for a cavity of the Single Spoke Resonator 1 subjected to a typical road transportation trip. A multibody model consisting of rigid bodies and finite element–imported flexible bodies has been created allowing a comparison of the simulated and experimental acceleration. Afterwards, an experimental on-road test, whose set-up is described in this article, has been carried out at Fermilab with instrumented components. Being able to effectively simulate and validate the dynamic effects on such sub-assemblies makes it possible, for the future, to simulate more complex structures subject to dynamic loadings, such as the entire cryomodules during shipping. Furthermore, the results from the simulations can be used to guide the design of new suspension systems suitable for the reduction mitigation of structural vibration during the road transportation of cryomodules.
“It’s a Racist Plot”: An Experimental Test of the Racial Defense
Authors: Crawford Nyron N.
Published: June 2021

Black municipal leaders are routinely accused of using race and racism to sidestep allegations that they have run afoul the ethics of public office. That is, they use racial defenses to respond to what they view as racist attacks against them. This type of race-based account has been treated as commonplace in American politics, but its effectiveness as a political account has received little scholarly attention. For example, how effective is the racial defense at minimizing negative political fallout for scandalized Black politicians? Using data from a survey experiment, I test how Black Americans respond to the political accounts profferred by Black elected officials accused of official misconduct. I show that a strategy involving a racial defense can yield positive evaluations in terms of trait judgment and voter intention, while offering no comment reduces participant suspicion about investigative malfeasance.
Planning the Barrio: Racial Order and Restructuring in Neoliberal Los Angeles
Authors: Huante Alfredo
Published: June 2021

Scholarship examining the legacy of early twentieth-century zoning and real estate practices on present-day urban landscapes has provided significant insight into the ways public officials appraised communities of color at the national and city scale. However, less is known about how local policy makers evaluated communities of color through the social movements of the 1970s and austerity policies of the 1980s. Analyzing Los Angeles City planning and administrative archives from the 1970s to 1990s, I assess how local policy makers arrived at regarding historically racialized and disinvested places such as Boyle Heights as potential sites of investment during the last quarter of the twentieth century. I find that city policy makers briefly categorized Boyle Heights as fit for preservation grounded in its socioracial composition and, later, designated the barrio as ancillary to intensifying efforts to revitalize downtown. Following the evolution of appraisals of land use during this period of transformation historicizes contemporary gentrification processes.
