Homicide associated with psychotic illness: What global temporal trends tell us about the association between mental illness and violence
Authors: Simpson Alexander IF , Penney Stephanie R , Jones Roland M
Published: December 2021

Available evidence suggests that persons with serious forms of mental illness are 4–10 times more likely to commit homicide as compared to non-affected members of the general population. The relationship between homicide and psychotic illness has now been subject to longitudinal investigation in six different populations across eight studies covering time periods over the last six decades. With the exception of one study, these investigations demonstrate that homicide associated with psychotic illness appears relatively stable through time and, in most populations, is not related to factors that contribute to the rise and fall of total population homicide (TPH) rates. This suggests that illness and treatment factors are of most importance if we are to reduce the prevalence of this tragic illness complication.

Authors: Sahoo Priyabrata , Pradhan Kalandi Charan , Nayak Tapaswini
Published: December 2021

This study examines the inclusiveness of poverty reduction among the newly formed states of undivided Andhra Pradesh by looking into the poverty among the different socio-religious groups both in the rural and urban regions during the 2000’s. The major proposition that has highlighted in this study: which socio-religious groups are more poverty ridden in the undivided Andhra Pradesh and its bifurcated states (Andhra Pradesh and Telangana)? The National Sample Survey Organisation unit level data (61st and 68th rounds) on Consumption Expenditure Survey have been used for the analysis. The result reveals that Telangana is having lower poverty level than Andhra Pradesh and records a faster reduction in poverty during 2004–2005 to 2011–2012. Andhra Pradesh constitutes around 70% of the total poor of the undivided Andhra Pradesh. This study found that most of the Scheduled Tribes, Scheduled Castes among the social groups and Muslims among the religious groups are more vulnerable and having higher head count ratio than the state average. Although several welfare programmes and schemes have already been implemented to eradicate poverty and inequality, still it is not effective in the ground level. Based on this argument, our study suggests that the schemes should focus on different sections of the people irrespective of rural and urban sectors in both the recently bifurcated states of Telangana and Andhra Pradesh.

Exploration of a new affordable thermal protection system utilizing 2.5D silica/polysiloxane composite
Authors: McDermott Ryan M , Tate Jitendra S , Koo Joseph H
Published: December 2021

Ablative materials are used as thermal protection systems (TPS) for reentry vehicles and solid rocket motor (SRM) nozzle applications. Phenolic and cyanate ester are the state-of-the-art (SOTA) resin systems used in many of the ablative composites today, including MX-2600 (silica/phenolic) from Cytec Solvay Group. While these ablatives have worked well, more demanding requirements drive the need for affordable lightweight advanced composites capable of handling high heat fluxes with minimal mass loss. These advanced ablative composites result in lighter reentry heat shields and solid rocket motors, increasing payload capabilities of spacecraft and rockets. Molding compound made of aerospace grade 99% SiO2 fabric and polysiloxane resin showed considerable improvement over MX-2600 in ablation properties in recent studies. In order to meet increased mechanical strength demands, NASA recently developed an ablative composite using a 3D quartz woven/cyanate ester composite material designed for the Orion spacecraft. While 3D woven composites provide excellent out-of-plane mechanical and ablation properties, they are very expensive, which limits their application. This research explores needle-punched silica fabric, sometimes referred to as 2.5D, which provides similar out-of-plane mechanical benefits to 3D woven composites in a more flexible VARTM manufacturing process at a much lower cost. The needle-punched silica fabric was infiltrated with polysiloxane resin and mechanical tests were performed. The needle-punched composites showed an increase of 181% in flexural strength, 27% in interlaminar shear strength, 2% in tensile strength, and 13% in compressive strength. In aerothermal ablation tests, the 2.5D out-performed the 2D laminate in char yield, mass loss, and recession rate; and in char yield and mass loss (%), the 2.5D out-performed the industry standard MX-2600 molding compound. The increased out-of-plane strength and char yield make it a promising and affordable ablative candidate for ablation performance with enhanced mechanical properties.
Exercise-Based Interventions Aimed at Improving Balance in Children with Autism Spectrum Disorder: A Meta-Analysis
Authors: Djordjević Mirjana , Memisevic Haris , Potic Srecko , Djuric Uros
Published: December 2021

Children with Autism Spectrum Disorder (ASD) often have deficits in motor skills, especially balance. This article presents a meta-analytic review of 15 intervention studies that aimed to improve balance in children and adolescents with ASD. Across these studies, there were 195 participants with ASD for whom pre-intervention and post-intervention balance scores were available. We measured the standardized mean difference (Hedges’ g) between their pre-intervention and post-intervention balance scores and found a large, positive effect from these balance interventions (standardized mean difference—1.82 (95% CI [1.34, 2.29]). Various balance intervention procedures were shown to be very efficacious for children and adolescents with ASD. Clearly, balance is a motor skill that is very susceptible to intervention efforts. We also provided recommendations to researchers regarding what information to include when conducting intervention studies.
Instructional Guidance for Promoting Creativity in English as a Foreign Language Writing Classrooms: A Korean Case Study
Authors: Kim Hyun-Ju , Gray Stewart , Lange Christopher
Published: December 2021

As student creativity is increasingly emphasized in English as a Foreign Language education, it is necessary to consider instructional techniques to encourage it. This study examines the effectiveness of two instructional techniques on creative writing performance of English as a Foreign Language students in a South Korean university. These techniques are variations of brainstorming known as mind mapping and SCAMPER. Survey data from the participants ( n = 39) were analysed to determine which technique resulted in higher levels of perceived creative output (essays). Additionally, a creativity rubric was developed and used to assign analytic scores to the essays to examine the relative benefits of the two techniques for high and low creative ability students. Results show that SCAMPER produced statistically significantly higher levels of perceived creative output. The essays written using SCAMPER generally received higher creativity scores than those written using mind mapping, though this difference was not statistically significant. Finally, results suggest that both techniques may help to narrow the performance gap between high and low creative ability students.
A robust H∞-based steering assistance system for the wheeled tractor
Authors: Shen Cheng , Liang Suming , Liang Jinhao , Yin Guodong
Published: December 2021

Agricultural machine automatic navigation poses great challenge to the precise agricultural technology system nowadays. To this end, this paper proposes a novel steering assistance system (SAS) to assist drivers in the path-tracking. First, the driver steering model is investigated through the driver simulator tests. Combining the wheeled tractor kinematics model, a driver-vehicle model is developed. Then, a polytopic linear parameter-varying (LPV) system is adopted to describe the uncertainties, including time-varying driver model parameters and velocity, in the model, based on which an output-feedback robust controller is developed to ensure robust stability within the polytope space. Moreover, a regional pole placement method is adopted to improve the transient performance of the system. Finally, driver-in-the-loop and field tests conducted to value the controller. The results show the effectiveness of the proposed method to improve the path-tracking performance for the agricultural machine navigation, while reducing the physical and mental workload of drivers. This control method is expected to be a paradigm for the precise navigation system of the agricultural machinery.
Formation control method based on artificial potential fields for aircraft flight simulation
Authors: Costa Andre N , Medeiros Felipe LL , Dantas Joao PA , Geraldo Diego , Soma Nei Y
Published: December 2021

As simulation becomes more present in the military context for variate purposes, the need for accurate behaviors is of paramount importance. In the air domain, a noteworthy behavior relates to how a group of aircraft moves in a coordinated way. This can be defined as formation flying, which, combined with a move-to-goal behavior, is the focus of this work. The objective of the formation control problem considered is to ensure that simulated aircraft fly autonomously, seeking a formation, while moving toward a goal waypoint. For that, we propose the use of artificial potential fields, which reduce the complexities that implementing a complete cognition model could pose. These fields define forces that control the movement of the entities into formation and to the prescribed waypoint. Our formation control approach is parameterizable, allowing modifications that translate how the aircraft prioritize its sub-behaviors. Instead of defining this prioritization on an empirical basis, we elaborate metrics to evaluate the chosen parameters. From these metrics, we use an optimization methodology to find the best parameter values for a set of scenarios. Thus, our main contribution is bringing together artificial potential fields and simulation optimization to achieve more robust results for simulated military aircraft to fly in formation. We use a large set of scenarios for the optimization process, which evaluates its objective function through the simulations. The results show that the use of the proposed approach may generate gains of up to 27% if compared to arbitrarily selected parameters, with respect to one of the metrics adopted. In addition, we were able to observe that, for the scenarios considered, the presence of a formation leader was an obstacle to achieving the best results, demonstrating that our approach may lead to conclusions with direct operational impacts.
Life in This World and For the Life of the World: Natural Science and the Social Ethos of the Orthodox Church
Authors: V. Simmons Frederick
Published: December 2021

For the Life of the World: Toward a Social Ethos of the Orthodox Church (FLOW) is an admirable and important document, not least because it affirms natural scientific insights as valuable resources for Christian theology and social teaching. Given the current Ecumenical Patriarch's extensive engagement with environmental concerns, this affirmation is especially apposite. However, I do not believe FLOW fully recognizes the implications of such insights for its conception of God's creation or its social ethos. In particular, FLOW maintains that scarcity, competition, violence, and death are distortions of God's creation due to human sin and that human beings are commissioned and capacitated by God to strive to overcome them. By contrast, I contend that contemporary scientific understandings of planetary forces and ecological processes—and indeed Christian scripture—give Christians cause to consider scarcity, competition, violence, and death aspects of God's creation. I further claim that striving to overcome scarcity, competition, violence, and death would be environmentally disastrous and spiritually deleterious since it would domesticate the rapidly disappearing wilderness that biblical wisdom literature depicts as delighting and glorifying God. Happily, allowing natural scientific insights to inform Orthodox conceptions of God's creation in this way would render FLOW's injunction that human beings redress the environmental implications of their sin an imperative to reduce and remedy pollution and to minimize and restore anthropogenic habitat degradation and destruction, thereby fostering the ecological sustainability Orthodoxy champions and the respect for wilderness Christians have multiple reasons to commend. Although this abandons FLOW's aspiration that human beings wholly civilize God's creation, such respect for wilderness does not imply acquiescence to human deprivation and distress, for just as it is inappropriate to impose cultural values on all of nature, it is wrong to regard all natural dynamics culturally normative. Similarly, attributing scarcity, competition, violence, and death to God's creation rather than its sin need not undermine Christian hopes for freedom from these and all other maladies, for Christians await not only God's salvation from sin and its effects but God's new creation too. Thus, in addition to honing Orthodoxy's social ethos, heeding FLOW's embrace of natural scientific insights as constructive theological resources foregrounds a commonly neglected dimension of Christians' traditional depiction of the divine economy.
For the Life of the World: Appreciation and Critique
Authors: Bowlin John
Published: December 2021

There are many things in For the Life of the World ( FLOW) 1 that deserve mention, gratitude, and praise from a Protestant theological ethicist, many things that the Protestant churches might learn, emulate, and modify in light of their own commitments about salvation, sacrament, and union with God. I mention three. I conclude by considering the view of moral tragedy that FLOW assumes. In recent years, several Protestant ethicists have been tempted to endorse a similar view. I offer reasons for Christians of all kinds to resist this temptation.
For the Life of the World: Some Reflections
Authors: Porter Jean
Published: December 2021

As its title would suggest, For the Life of the World: Towards a Social Ethos of the Orthodox Church offers a comprehensive statement of the ideals and principles that should guide Orthodox Christians, and the church itself, in the effort to live a Christlike life in today's pluralistic society. The expression “social ethos” might suggest that this document limits itself to social questions as these are commonly understood, offering a kind of Orthodox equivalent of Roman Catholic social encyclicals. On examination, it is clear that this document goes beyond the standard topics pursued under the rubric of social ethics. It includes an extended discussion of marriage and family life, addressing questions of marital relations and family dynamics as well as the social dimension of marriage; a comparably extended discussion of medical ethics; extended comments on ecumenical and interfaith relations; and reflections on the liturgy as the ultimate context for the moral life. We even find brief but perceptive remarks on our treatment of animals. This document is not so much a presentation of social ethics as a treatise on moral theology comprehensively considered. The nearest Roman Catholic parallel would be Veritatis Splendor, rather than one of the social encyclicals.
Fostering Youth Sociopolitical Action: The Roles of Critical Reflection, Sociopolitical Efficacy, and Transformative Student Voice
Authors: Hipolito-Delgado Carlos P. , Stickney Dane , Kirshner Ben , Donovan Courtney
Published: December 2021

Critical pedagogies often prioritize critical thinking and social awareness at the expense of preparing urban youth for social action. Though sociopolitical efficacy is argued to bridge critical reflection and social action, this relationship is undetermined. We argue that critical reflection and sociopolitical efficacy are independent predictors of sociopolitical action. We surveyed 158 high-school students and found that critical reflection and sociopolitical efficacy were positively related to sociopolitical action. Additionally, participation in transformative student voice (TSV) and classroom leadership opportunities positively influenced sociopolitical efficacy. We argue that educators and community organizers should promote leadership development and TSV activities to encourage youth sociopolitical efficacy and action.
Research on Design Method for Optimal Flow Rate of U-shaped Geothermal Well Based on Exergy Analysis
Authors: Xiao Dong , Xu Jiaxin , Wang Tianduoyi , Cai Chun , Li Li , Liu Jianhong
Published: December 2021

Closed-loop U-shaped geothermal wells show great potential owing to their special well-depth structure, which can provide a good flow rate and heat extraction. However, no advanced process parameter optimization method is available for U-shaped geothermal wells. To effectively describe the heat transfer processes of U-shaped geothermal wells, an analytical solution that couples transient heat conduction in the surrounding soil (or rocks) with the quasisteady heat transfer process in boreholes was developed. This modelling approach depends on many common elements, such as the thermophysical properties of the working fluid and series of resistances for various elements in the wellbore. Subsequently, based on the exergy analysis method, the optimal operating flow rate was defined and a design method for the optimal flow rate was developed. Results indicate that to obtain the maximum exergy efficiency, different optimal flow rates for the U-shaped geothermal well are achieved at different stages of the heating period. This findings of this study expand the research ideas of the process parameter optimization of U-shaped geothermal wells and provide a theoretical basis for developing an optimal circulating-flow-rate design for U-shaped geothermal wells.
A Case Report of Inflammatory Myofibroblastic Tumor of the Sphenoidal Sinus
Authors: Wu Shuo , Jian Feitong
Published: December 2021

Inflammatory myofibroblastic tumor (IMT) is a tumor composed of differentiated myofibroblastic spindle-shaped cells. It occurs in the soft tissues of the abdomen and lungs, and is very rare in the sphenoid sinus. The diagnosis depends on histopathology and immunohistochemistry, and is easily misdiagnosed. Although metastasis is rare, the recurrence rate is high. Surgical resection is the treatment of choice, and where complete resection is difficult, radiation therapy, hormonal therapy, or molecular targeted drug therapy can be administered. We report a rare case of IMT with a primary origin in the sphenoid sinus, which was entirely resected by nasal endoscopy and confirmed by histological examination.
Diversifying the Deliberative Turn: Toward an Agonistic RRI
Authors: Scott Deborah
Published: December 2021

In its “deliberative turn,” the field of science and technology studies (STS) has strongly advocated opening up decision-making processes around science and technology to more perspectives and knowledges. While the theory of democracy underpinning this is rarely explicitly addressed, the language and ideas used are often drawn from deliberative democracy. Using the case of synthetic biology and Responsible Research and Innovation (RRI), this paper looks at challenges of public engagement and finds parallels in long-standing critiques of deliberative democracy. The paper suggests that STS scholars explore other theories of decision-making and explores what an RRI grounded in agonistic pluralism might entail. An agonistic RRI could develop empirical research around questions of power relations in contemporary science and technology, seek to facilitate the formation of political publics around relevant issues, and frame different actors’ stances as adversarial positions on a political field rather than “equally valid” perspectives.
Did the Hospital Readmissions Reduction Program Reduce Readmissions? An Assessment of Prior Evidence and New Estimates
Authors: Ziedan Engy , Kaestner Robert
Published: December 2021

In this article, we provide a comprehensive, empirical assessment of the hypothesis that the Hospital Readmissions Reduction Program (HRRP) affected hospital readmissions. In doing so, we provide evidence as to the validity of prior empirical approaches used to evaluate the HRRP and we present results from a previously unused approach to study this research question—a regression-kink design. Results of our analysis document that the empirical approaches used in most prior research assessing the efficacy of the HRRP often lack internal validity. Therefore, results from these studies may not be informative about the causal consequences of the HRRP. Results from our regression-kink analysis, which we validate, suggest that the HRRP had little effect on hospital readmissions. This finding contrasts with the results of most prior studies, which report that the HRRP significantly reduced readmissions. Our finding is consistent with conceptual considerations related to the assumptions underlying HRRP penalty: in particular, the difficulty of identifying preventable readmissions, the highly imperfect risk adjustment that affects the penalty determination, and the absence of proven tools to reduce readmissions.
Achieving effective interprofessional practice between speech and language therapists and teachers: An epistemological perspective
Authors: Quigley Duana , Smith Martine
Published: December 2021

Interprofessional practice between speech and language therapists and teachers involve sharing knowledge and experiences to achieve a common goal of improving child outcomes. Although interprofessional practice has widespread support from both disciplines, it is not always easily implemented in day-to-day practice and numerous challenges have been documented. This study attempts to address these challenges through an epistemological perspective of interprofessional practice between teachers and speech and language therapists. Action research methodology was employed for this inquiry that spanned the duration of a school year. Data analysis placed an explicit focus on the experiences of interprofessional practice between the speech and language therapist and teachers, including an examination of how action was agreed and the processes underpinning collaborative working. An epistemological lens facilitated a more in-depth consideration of the diverse ways of knowing implicit in interprofessional practice and provided guidance on how to overcome the barriers, and realise the potential, of collaboration between speech and language therapists and teachers in daily practice. Four factors, rooted in an epistemological perspective, were generated from the analyses as core tenets of effective interprofessional practice. These included securing a participatory space; actively facilitating power-sharing; balancing the status of practical knowing with propositional knowing and anchoring interprofessional practice in collaboratively designed, practical activities that integrate ways of knowing. The former four factors, and their implications, offer concrete and practical direction for practitioners and educators on how to achieve effective interprofessional practice to help improve child outcomes collaboratively.
Legitimation work in sustainable entrepreneurship: Sustainability ventures’ journey towards the establishment of major partnerships
Authors: Riandita Andra , Broström Anders , Feldmann Andreas , Cagliano Raffaella
Published: December 2021

Sustainable entrepreneurship, that is, venturing with the aim of contributing to a shift of practices towards environmental and social sustainability, is an increasingly prominent phenomenon. This article investigates how sustainability ventures orient between dual – commercial and environmental – logics when conducting the legitimation work necessary to secure their first major partnership with an incumbent firm. Specifically, we study multiple cases of partnerships on food waste reduction. This setting is characterised by limited tension between the two logics, which implies that ventures are not forced into hybridity. We find some indications that ventures are able to draw on both types of logic to legitimate their ventures. However, the dominant pattern is that sustainability ventures tend to orient their legitimation work around a salient founding logic. Our analysis suggests that this pattern can be attributed partly to organisational imprinting, but also to legitimation work in this context being inherently logic-specific to a significant degree. This seems to be particularly true for ventures with a salient environmental logic.
Bilateral multifocal muscular hemorrhage in the triceps surae during antiplatelet therapy: a case report
Authors: Go Young-In , Kim Gi-Wook
Published: December 2021

Hemorrhagic complications are often reported following antiplatelet therapy; however, simultaneous multifocal hemorrhages in both legs are uncommon. The patient was a 75-year-old man diagnosed with ST elevation myocardial infarction who underwent percutaneous coronary intervention in the right coronary artery. He was prescribed oral acetylsalicylic acid and ticagrelor. Three days after initial drug treatment, he complained of bilateral leg pain that was aggravated by walking and moving his ankle across a broad range of motion. No deep vein thrombosis was detected on Doppler ultrasonography; however, muscular hemorrhage was suspected according to musculoskeletal ultrasonography. Multifocal muscular hemorrhage was confirmed in the soleus and gastrocnemius muscles on magnetic resonance imaging. To reduce the risk of bleeding, we changed the medication from ticagrelor to clopidogrel. The patient performed leg elevation exercises, compression, and applied an ice pack. He also performed range of motion exercises and gait training in addition to receiving drug treatment. With these therapies, his pain score improved from 5 to 3 on a visual analog scale, without further complications. Multifocal muscular hemorrhage rarely occurs bilaterally; however, when it does occur, an appropriate treatment plan can be developed based on musculoskeletal ultrasonography.

Authors: Ma Liangliang , Chen Xuelin , Weng Shengfeng , Yang Xinting
Published: December 2021

Objective

To investigate the diagnostic value of the T cell spot (T-SPOT.TB) test, oxidation-related factors (ORF), and antimicrobial peptide LL-37 in patients with pulmonary tuberculosis (PTB) with type 2 diabetes.

Methods

A total of 560 patients with PTB admitted to our hospital from January 2019 to April 2021 were retrospectively included in this study. Of these, 232 patients with PTB and type 2 diabetes were assigned to the combined group, and 328 patients without complications were assigned to the PTB group.

Results

Areas under the curve (AUCs) for the number of spot-forming cells in CFP10 and ESAT-6 test panels detecting PTB with type 2 diabetes were 0.892 (95% confidence interval [CI] 0.831–0.921) and 0.893 (95% CI 0.841–0.935), respectively. CFP10 combined with ESAT-6 had the highest diagnostic value, with sensitivity and specificity levels and an AUC of 87.73%, 88.93%, and 0.942 (95% CI 0.907–0.967), respectively. The levels of total antioxidant capacity, superoxide dismutase, and catalase in the combined group were lower than in PTB and control groups.

Conclusion

The combination of T-SPOT.TB, ORF, and LL-37 in the diagnosis of pulmonary tuberculosis with type 2 diabetes mellitus has a high diagnostic value and clinical application value.
“Writing's intimate spatialities: Drawing ourselves to our writing in self-caring practices of love”
Authors: DeLyser Dydia
Published: December 2021

This Commentary outlines four conceptual-spatial challenges of academic writing, and suggests an approach to navigating them. Academic writing, as feminist economic geographers argue, is underpinned by difference: emerging from and produced through different positionalities, differing access to stable employment and material, temporal and spatial resources, all set within structures of power and inequity—significant among them the neoliberal university. At the same time, for academics writing demands space in our lives: temporally, locationally, conceptually, and emotionally. Because these spatialities are potentially different for each writer each time we write and because they engage us spatially at a personal level, I term them writing's intimate spatialities, and suggest that care-fully navigating these conceptual-spatial challenges of academic writing stakes out a political position, one that may now be more important than ever: In an academic environment of neoliberalism and increasing precarity, I suggest that writing's prevalent emotional apprehensions may be able to be affirmatively conceptualized as a labor of self-care we come to with love.
Photovoice Exploration of Frontline Nurses’ Experiences During the COVID-19 Pandemic
Authors: Rana Ruhina , Kozak Nicole , Black Agnes
Published: December 2021

Background

The current COVID-19 global pandemic has had a profound impact on the health care system and on the physical and psychological well-being of nurses. Previous pandemics have led to nurses leaving the profession. Therefore, it is important that we hear the voices of nurses who experienced the pandemic on the frontlines to influence future planning and policy development.

Purpose

The purpose of this study was to explore frontline nurses’ experiences during the COVID-19 pandemic through photos, narratives, and group discussions.

Methods

Twelve nurses in two groups shared their lived experiences through Photovoice, a participatory action approach. Photos and narratives were collected over five weeks per group. One group at the beginning of the pandemic and the other group six months later. Focus group discussions were held following each group.

Results

Five themes emerged from the photovoice data: (1) The work of nursing; (2) Miscommunication; (3) Fatigue; (4) Resilience; and (5) Hope for the future. Various subthemes were noted within each theme to delineate the lived experience of frontlines nurses working in the COVID-19 pandemic.

Conclusions

The voices of nurses and their experiences on the frontlines of the COVID-19 pandemic need to be considered in pandemic planning and integrated into health care policy, guidelines, and structural changes.
“Isn’t There Any Other Way than Calling the Cops?”: How Differences in Initiation of Police Intervention Influence Survivor Safety
Authors: Nnawulezi Nkiru , Engleton Jasmine , Jumarali Selima , Royson Samantha , Murphy Christopher
Published: December 2021

As formal crisis responders, police are trained in de-escalation tactics that are expected to mitigate intimate partner violence and promote survivor safety. However, the alignment between expected and actual practice of police intervention varies, especially when the survivor does not initiate the call, police treat the survivor poorly, or provide an undesirable arrest outcome. At best, unsuccessful interventions do not change survivors’ risk level, and at worse, elevate their risk of experiencing harm. The purpose of this qualitative study was to explore survivors’ perspectives on the process of police intervention, specifically how variations in initiation, quality of engagement, and arrest influence survivors’ safety. Twenty-four women whose partners were in a relationship violence intervention program were recruited to participate in the study. Results showed that many survivors described a range of ongoing, strategic violence perpetrated by their partners that required intervention; yet the complex nature of the violence often extended beyond police capacity. Either survivors called the police, or they were initiated externally by neighbors or strangers; some survivors had dual initiations. Whether survivors reported that police used safety practices during the intervention was related to who initiated the police. Arrests of abusive partners were inconsistent, and they varied based on number of previous calls to the police and visible signs of injury. Survivors of color, specifically Black women, self-initiated at higher rates, experienced fewer safety strategies used by police, and had fewer arrests. No matter the outcomes of police intervention, survivors actively engaged in strategies outside of formal systems to protect themselves and their families. Study results imply that police intervention may be ill-suited to support survivors’ safety goals and highlight a need for alternative interventions focused on de-escalation and prevention.
Digital activism and collective mourning by Chinese netizens during COVID-19
Authors: Cao Xun , Zeng Runxi , Evans Richard
Published: December 2021

This study examines the discursive practice of mourning and commenting by netizens on the final social media post made by Dr Li Wenliang, regarding it as a form of political participation and competitive discursive politics enacted in cyberspace. Discourse theory is applied to conduct discourse analysis on 4000 comments. We identified two strategies that netizens used to establish an alternative space for discourse. The first involved hidden protests expressed through multi-semantic mourning, avoiding suppression by indirectly challenging official authorities. Second, through engagement with microblogs, netizens applied personalized narratives to form a collective memory and a counter-memory space that departed from the official normative narrative. Discursive activities enacted by netizens stimulated the political agenda of resilient adjustment on the part of the authorities, leading the government to accept and incorporate public demands into policies through strategic rectification. These findings help to better understand the significant power of disorganized connective action that is reliant on affective citizens and the further development of regime resilience on the part of the Chinese political system in response to digital activities.
Modelling, analysis and experimental verification of air disc brake used in heavy duty vehicles
Authors: Güleryüz İbrahim Can , Yılmaz Barış
Published: December 2021

This paper proposes a reliable mathematical model that can be used for design stage of new air disc brake (ADB) development projects. All three phases of braking mechanism (brake apply, brake release and automatic adjustment) are modelled by Matlab Simulink in consideration of hysteresis and adjuster performance experiments. Firstly, mathematical relations of each friction interfaces of air disc brake components are derived and mathematical equations adapted to the Simulink model. To ensure the accuracy of ADB system model, hysteresis and adjuster performance experiments are conducted on a prototype disc brake mechanism supported by a test fixture. This prototype single piston disc brake mechanism is fitted to wheel size in 17.5″ used in heavy commercial vehicles. The predicted clamping force, mechanical ratio, brake efficiency and adjuster rate results are verified by using experimental data. The maximum deviation in hysteresis results is 3.08%. Besides, the maximum deviation in adjuster performance results is 7.15%. The numerically and experimentally obtained hysteresis and adjuster performance results show good agreement. The proposed model is modified in consideration of mechanism supported by a brake calliper for predicting actual performance of single piston brake mechanism on the brake level. The hysteresis and the adjuster performance analyses are conducted by using modified ADB model to calculate the hysteresis based brake efficiency and the adjuster rate. The brake efficiency of new single piston brake design provides similar efficiency as the twin piston disc brake used in heavy commercial vehicles.

Published: December 2021

In this study, the Group of 20 (G20; excluding EU economies) were selected as the research objects, and the dynamic network slacks-based model (SBM) was used to evaluate the impact of carbon dioxide (CO2) emissions and forested area on the efficiency and productivity of the industrial and agricultural sectors from 2011 to 2015.

Empirical results showed that: (1) The efficiency of the industrial sector was superior to that of the agricultural sector among the G20 countries. Argentina, Australia, Indonesia, Saudi Arabia, South Africa, Turkey, the UK, and the US maintained the best industrial sector efficiency values, falling on the efficiency boundary, whereas Argentina, Brazil, Canada, France, Indonesia, South Korea, Russia, and the US had the best agricultural sector efficiency values. (2) Argentina, Indonesia, and the US had the best overall efficiency value of G20 countries. Saudi Arabia (0.0303), China (0.2721), and the UK (0.2809) had the lowest efficiency values. (3) Only France and Germany had higher than average total factor productivity, while Indonesia and Saudi Arabia had declining industrial and agricultural sector productivity. (4) The proportion of forested area (546.02%) was the most important variable to be improved due to the influence of desert topography, followed by the proportion of agricultural output values (60.86%) and the proportion of industrial output values (38.02%) in some countries.

Authors: Ojo Ademola E. , Amassoma Ditimi
Published: December 2021

The Earth as a planet supports human life, living and activities, attracting extensive and intensive socioeconomic influences on the economy. Such activities like infrastructures development exerts increasing and divers environmental quality concerns and hence the economic growth. While these variables appear interrelated due to many factors including population growth, urbanisation, etc. However, the relationship between infrastructures, environment and economic growth is not largely known especially in Nigeria. This study therefore investigated their relationship using time series data between 1990 and 2019 by adopting Co-integration estimation technique through the Bound test approach of auto regressive distributive lag method using percentage share of building and construction sector of gross domestic product (GDP), carbon dioxide, population growth GDP growth rate, etc. as variables. The study revealed that the infrastructures development and environmental quality explain economic growth and have both short and long run relationships while specifically population growth and agriculture, forestry, fishing, value added variables are positively significant to economic growth. The findings evidences of both short and long run relationships among the variables are significant and it is consequently recommended that new roles for infrastructure sets and production processes should consider environmental quality mindsets to achieve positive green economy outcomes in Nigeria.

Published: December 2021

To investigate the maternal and neonatal risk factors related to pregnancy and birth affecting the occurrence of neurodevelopmental disorders to their children using the medical claim data for the whole population. The study was conducted on all the babies born in Korea from 2005 to 2009 based on data from the National Health Information Database. All birth records were tracked from birth to December 31, 2015. To analyze factors related to the mother, data related to the mother of the newborn were collected. Increased maternal age was found to increase the risk of cerebral palsy (adjusted odds ratio [aOR] = 1.46) and autism spectrum disorder (aOR = 1.48), while lowering the risk of intellectual disability (aOR = 1.83) and speech and language impairment (aOR = 1.41) compared with the reference group aged 25 to 29 years old. The incidence affected by socioeconomic factors varied according to the types of disorders. Among various risk factors, prematurity or low birth weight, problems associated with amniotic fluid or amniotic membrane, preeclampsia or eclampsia, and cesarean section affect the incidence of neurodevelopmental disorders. To reduce the incidence or severity of neurodevelopmental disorders, a better understanding of the risk factors of neurodevelopmental disorders is important. The results of this study can be used as basic data to help such understanding.
‘Dual’ labour market? Patterns of segmentation in European labour markets and the varieties of precariousness
Authors: Seo Hyojin
Published: December 2021

This article aims to empirically explore how European labour markets are segmented and who the outsiders are. The article moves beyond the dichotomous approach to understanding labour market division, often based solely on examining employment relationships. Taking a multi-dimensional approach to defining labour market precariousness, this study incorporates aspects such as income, job prospects and subjective insecurity. Latent Class Analysis is used on data taken from the 2015 European Working Conditions Survey to extend the traditional definition of outsider-ness. Four labour market segments are found: insiders and three different types of outsiders: typical outsiders, dead-end insiders and subjective outsiders. Looking at the cross-national aspect, variations are found in the segmentation patterns, especially in terms of who the outsiders are. The findings show the need to examine various aspects of labour precariousness in order to capture the complexity of post-industrialised labour markets and identify different types of outsiders across Europe that need to be protected for building a more cohesive society.
APCDs can Provide Important Insights for Surveilling the Opioid Epidemic, With Caveats

State-level all-payer claims databases (APCDs) are a possible new public health surveillance tool, but their reliability is unclear. We compared Colorado’s APCD with other state-level databases for use in monitoring the opioid epidemic (Colorado Hospital Association and Colorado’s Prescription Drug Monitoring Program database for 2010–2017), using descriptive analyses comparing quarterly counts/rates of opioid-involved inpatient and emergency department visits and counts/rates of 30-day opioid fills between databases. Utilization is lower in the Colorado APCD than the other databases for all outcomes but trends are parallel and consistent between databases. State APCDs hold promise for researchers, but they may be better suited to individual-level analyses or comparisons of providers than for surveillance of public health trends related to addiction.
A pilot study about methods to reduce prescription errors in a chemotherapy day unit – Aspects to consider in pharmacist verification process

Published: December 2021

Introduction

Prescribing errors can happen unintentionally during the prescribing process, or when choosing a treatment therapy. Prescribing errors have the highest prevalence amongst common error types related to chemotherapy medication in outpatient settings. According to the Joint Commission International (JCI), prescriptions should be reviewed for appropriateness by someone else than the prescriber or practitioner to prevent medication errors.

Aim

The study was aimed to map out the existing type and amount of occurring deviations in prescribing and to clarify the current chemotherapy prescribing practices at the Comprehensive Cancer Center at Helsinki University Hospital. Similar research has not been published in Finland before.

Methods and patients

The researcher selected patients randomly from the daily outpatient attendance list following a predetermined numerical order. Data was collected by conducting a medication verification review in line with the JCI guidance by a clinical pharmacist the day before the patient's clinic appointment using the available medical documentation. A clinical pharmacist evaluated findings from prescriptions and contacted an oncologist if the findings were considered clinically significant.

Results

A clinical pharmacist verified prescriptions from 101 patients for appropriateness and found discrepancies in four percent of the prescriptions ( n = 4/101). The oncologist approved 50 percent of the suggested amendments by the pharmacist as clinically significant ( n = 2/4). The study revealed that patient’s regular home medications were not always correctly recorded into the database, so verification of medicine interactions could not be trusted as completely accurate. It took on average 16 min per patient to perform a medication verification review. The process was slowed down by the lack of detailed enough protocols for this purpose and the current patient care record system not having structural formatting of data entry.

Conclusions

Verification of prescriptions provides a tool to identify prescribing discrepancies and to prevent unintended medication errors affecting patients. The development of detailed protocols and guidelines, as well as an appropriate training program, would support pharmacists in compiling clinical medication reviews for chemotherapy patients. More research is needed to further develop the operating model in Finland. Information gathered from this study can be used for identifying training requirements.
