Taxing Faith: Halo Effect and the Implications of Taxing Canadian Places of Worship
Authors: Wood Daly Mike
Published: October 2020

In Canada, the social, spiritual and communal value of local worshipping congregations has long been accepted. The value that Canadians place on these organizations is reflected in their charitable status and the tax-free benefits this affords. But with increasing costs, and governments at all levels needing to mine new sources of revenue, there is increasing pressure from some segments of Canadian society to reduce or eliminate this charitable status. Drawing on data from the Halo Canada project, the author puts forward a socio-economic case for maintaining the charitable status of places of worship, suggesting that the socio-economic or Halo Effect of congregations outweighs the benefits of government taxation by more than ten times.
Quasistatic response of a shear-thickening foam: Microstructure evolution and infrared thermography

Published: October 2020

In this work, the authors study the thermo-mechanical response of a dilatant polymeric foam in quasistatic tension and compression, focusing on the links between microstructure, mechanical response, and associated temperature rises in these materials. The authors study these links for a commercially-available shear-thickening foam, named D3O LITE D. Samples were tested under quasi-static conditions for a strain rate of 0.1 s−1 in tension and compression. Micro X-ray computed tomography (XCT) was used to study the evolution of microstructure (pore size and wall thickness) as a function of strain and this was achieved by developing MATLAB-based programs to analyze these microstructural features. The foam specimens were loaded until failure which allowed for the investigation of the elastic, inelastic, and failure regimes. From the XCT images, pore stretching and cell wall tearing are observed in tension, and buckling and pore collapse are observed in compression. These mechanisms are studied in-situ using an infrared thermal camera which record temperature profiles, and temperature measurements are linked back to stress-strain, and temperature-strain responses. For this material, the tensile yield stress was 0.57 ± 0.10 MPa and the elastic modulus was 5.47 ± 0.10 MPa respectively, at a yield strain of 0.10 ± 0.04. At the time of failure, the average temperature of the specimen was found to increase by ∼3.00°C and a local temperature increase of ∼8.00°C was observed in the failure region. In compression, the elastic collapse stress and elastic modulus were found to be 0.130 ± 0.016 MPa and 2.5 ± 0.2 MPa, respectively. The temperature increase in compression at ∼0.83 strain was ∼0.65°C. These results represent some of the first mechanical properties on shear-thickening foams in the literature, and the discoveries on the linkages between the microstructure and the mechanical properties in this study are important for researchers in materials design and modelling.
Identification of plasticity-controlled creep and fatigue failure mechanisms in transversely loaded unidirectional thermoplastic composites
Authors: Erartsın Ozan , Drongelen Martin van , Govaert Leon E.
Published: October 2020

In continuous fiber-reinforced thermoplastics, the macroscopic failure mode in transverse long-term failure is dominated by a brittle crack-growth mechanism. Neat thermoplastic matrices, on the other hand, generally display also a plasticity-controlled mechanism in long-term loading at elevated stress levels and/or temperature. This failure mechanism requires a different approach to lifetime prediction than crack growth; hence, it is important to identify it in the long-term performance of composites.

In this study, we demonstrate the presence of the plasticity-controlled failure mechanism in long-term failure of transversely loaded unidirectional (UD) thermoplastic composites made of glass/iPP, carbon/PEEK and carbon/PEKK. The main method used is to compare the lifetime in cyclic loading to that in static loading at the same level of maximum stress, where an increase in lifetime is characteristic for plasticity controlled failure, and, vice versa, a decrease is indicative for fatigue crack growth. In addition, the applicability of a lifetime prediction method common to plasticity-controlled failure of neat thermoplastics is evaluated for the composites investigated.

The results of this study indicate that the plasticity-controlled failure was present in composites, although the extent to which the effects are present varied depending on the materials investigated. Glass/iPP showed the most explicit evidence of the plasticity-controlled failure over the entire load range experimentally covered. Its long-term failure was delayed with a decrease in the stress ratio and lifetime was predicted well using the principles of plasticity-controlled failure.
Narrating Crisis From War Zones to Disease Zones
Authors: Daiute Colette
Published: October 2020

Previous research with young people growing up during and after wars offers insights for how youth are understanding and coping with the COVID-19 crisis. This literature review summarizes findings from research with adolescents who shared their experience and knowledge in war zones as those findings apply to research with youth in this pandemic. Circumstances of the COVID-19 pandemic differ in important ways from military wars, yet emerging research explains how abrupt disruptions of daily life and consequences like lack of social support and uncertainty challenge young people’s psychosocial orientations and health. A brief review of issues relevant to youth in crises sets the scene for a discussion of how their uses of narratives in war zones engaged powerful psychosocial processes, including sense making, imagining, and advising, and how those processes apply to youth narrating in disease zones. Focus is on how such discourse activities symbolically manage instability, uncertainty, and separation challenging youth in the COVID-19 era. Because narrating is an interactive process, adults’ open invitations and empathetic listening to youth storytelling are, moreover, pivotal for supporting youth expression rather than shutting it down. The article concludes with implications for future research with youth growing up in the COVID-19 crisis.
Making the World a Better Place: How Crowdfunding Increases Consumer Demand for Social-Good Products
Authors: Simpson Bonnie , Schreier Martin , Bitterl Sally , White Katherine
Published: October 2020

Crowdfunding has emerged as an alternative means of financing new ventures wherein a large number of individuals collectively back a project. This research specifically examines reward-based crowdfunding, in which those who take part in the crowdfunding process receive the new product for which funding is sought in return for their financial support. This work illustrates that consumers make fundamentally different decisions when considering whether to contribute their money to crowdfund versus purchase a product. Six studies demonstrate that compared with a traditional purchase, crowdfunding more strongly activates an interdependent mindset and, as a result, increases consumer demand for social-good products (i.e., products with positive social and/or environmental impact). The research further highlights that an active involvement in the crowdfunding process is necessary to increase demand for social-good products: when a previously crowdfunded product is already to market, the effect is eliminated. Finally, it is demonstrated that crowdfunding participants exhibit an increased demand for social-good products only when collective efficacy (i.e., one’s belief in the collective’s ability to bring about change) is high.
“Maybe One Day I Will also be Almito”: Ethiopian Israelis, Naming, and the Politics of Immigrant Identity
Authors: Walsh Sophie D , Yakhnich Liat
Published: October 2020

The issue of name change, and in particular name reclaiming (i.e., taking back a heritage name), among immigrants has been rarely studied academically, despite its centrality to immigrant identity and immigration experiences. Immigrants, in many countries, are often encouraged or pressured to change their names, but in recent years, some have chosen to reclaim their heritage or original names. This article analyzes the practice of name reclaiming among young Israelis of Ethiopian heritage, a community that has experienced racial discrimination. Data were gathered through a qualitative phenomenological study of 19 young adults who immigrated to Israel from Ethiopia as minors. The analysis yielded two simultaneous dialogues: an internal dialogue in which individuals described their personal experience of name reclaiming and an external dialogue in which name reclaiming reflected a political and social process through which a discriminated minority could express increased feelings of power and agency. The results enrich the study of migration by showing the ways in which personal and social-political processes experienced by a discriminated minority intertwine, as vividly illustrated by the specific case of name reclaiming.
Associations of self-reported vision problems with health and psychosocial functioning: A 9-year longitudinal perspective
Authors: Wettstein Markus , Spuling Svenja M , Hans-Werner-Wahl  , Heyl Vera
Published: October 2020

Impaired vision often results in restrictions across diverse key indicators of successful aging. However, little is known about how impaired vision affects the long-term trajectories of these outcomes, whether effects are moderated by age, and whether psychosocial resources beyond well-being such as subjective age views are also affected by vision loss. We analyzed how self-reported vision problems as a time-varying predictor are related to long-term changes in health and cognitive ability (functional health, number of chronic diseases, self-rated health, information processing speed), well-being (life satisfaction, positive and negative affect, depressive symptoms, loneliness), and subjective age views (subjective age; aging-related cognitions: social loss, physical decline, continuous growth). Our sample was derived from the German Ageing Survey, comprising 6,378 individuals (40–89 years) who provided up to four observations over a 9-year period. Controlling for gender, age, education, and functional as well as self-rated health, we observed that both on a between- and a within-person level, indicators of successful aging were consistently less favorable among individuals with more vision problems. Associations between vision problems and functional health became stronger with advancing age. In contrast, with increasing age, vision problems were less closely associated with change in several indicators of psychosocial functioning. Our findings suggest that self-reported visual impairment is associated with restrictions across a broad range of developmental domains. Some detrimental effects of vision problems are augmented in later life, whereas several effects on well-being and subjective age views were attenuated with advancing age, which might indicate processes of late-life adaptation to vision loss.
Life Domains and Dating Violence Among Latino Youth: A Partial Test of Agnew’s Integrated General Theory
Authors: Zavala Egbert , Muniz Caitlyn N.
Published: October 2020

In 2005, Agnew presented a new theoretical framework for understanding crime and delinquency. To date, this theory has not been thoroughly tested among various populations and types of crime. To address this gap in the research, the present study analyzes data gathered from the Dating Violence Among Latino Adolescents Study, providing a partial test of Agnew’s integrated general theory to determine its applicability to dating violence perpetration among Latino youth. Results from 669 Latino respondents showed that the theory’s constructs are modestly associated with perpetrating dating violence among this study population. Concepts depicting self (anger) and peer (peer bullying) domains are associated with the dependent variable, while school (school performance) and family (family support) domains were found to be nonsignificant. Among control and demographic variables, age, sex, depression, anxiety, and past dating victimization were also significant, while enculturation was nonsignificant. Overall, results are indicative of partial support for the theory. Prevention and intervention strategies based on the study’s findings targeted at reducing dating violence perpetration, such as recognizing signs of anger and reducing peer bullying victimization, are discussed.

Published: October 2020

Fumarase deficiency (FD) is a rare and severe autosomal disorder, caused by inactivity of the enzyme fumarase, due to biallelic mutations of the fumarase hydratase ( FH) gene. Several pathogenic mutations have been published. The article describes an infant with failure to thrive, microcephaly, axial hypotonia, and developmental retardation with increased excretion of fumarate, no activity of fumarase and a homozygous mutation of the FH gene, which was until recently only known as a variant of unknown significance. Carriers of pathogenic mutations in the FH gene are at risk for developing renal cell carcinoma and should therefore be screened. Both parents were healthy carriers of the mutation and had decreased levels of enzyme activity. In addition, the article presents an overview and analysis of all cases of FD reported thus far in the literature.
Migration Regime and “Language Part of Work”: Experiences of Syrian Refugees as Surplus Population in the Turkish Labor Market
Authors: Nimer Maissam , Rottmann Susan Beth
Published: October 2020

The literature on migration, language and employment is dominated by the human capital approach and promotes multilingualism as a universal good. This paper examines the relationship between language and work for migrants illustrating how they are ascribed value as capital according to their position and the “language part of work.” First, we trace a genealogy of the migration regime in relation to the labor and linguistic market of migrants in Turkey, characterized by informality and exploitation. Then, we look at the experiences of refugees qualitatively to show how language is differentially valued and has modest effects on social mobility. We argue that language learning instead of stemming from individuals’ possession of capital should be examined within a broader linguistic and employment framework. This research goes beyond conventional wisdom about the centrality of language as a means to improve employment by shedding light on the structure that shapes language value.
Ján Kollár’s Thoughts on Capital Punishment
Authors: Gluchman Vasil
Published: October 2020

This article analyses and assesses the arguments opposing capital punishment put forward by Ján Kollár (1793–1852), a representative of Central European Evangelical/Lutheran Enlightenment rationalism, using the definition of criminal practice in Europe at the turn of the nineteenth century as the basis. Consequently, the author pays attention to the movement for reform in criminal law and practices, initiated in Europe in the second half of the eighteenth century by Cesare Beccaria, including his argumentation against capital punishment. In this context, the author presents and investigates 13 arguments against capital punishment defined by Kollár in his 1815 diary. The author came to the conclusion that Kollár, in his arguments against capital punishment, followed, to a certain extent, the views of Beccaria and eighteenth -century adherents of the French Enlightenment; however, Kollár’s actual argumentation is rationalistically based on ethical values of humanity and justice with significant space also dedicated to utilitarian aspects of rejecting capital punishment adopted from reformists of criminal law.
Acculturation: Role of Student–University Alignment for International Student Psychological Adjustment
Authors: Bui Huyen T. N. , Selvarajah Christopher , Vinen Denis G. , Meyer Denny
Published: October 2020

The interaction between host environment and international students plays a critical role in the students’ cross-cultural adjustment. However, limited research has captured this interaction in investigating international student acculturation. Building on acculturation and person–environment fit theories, this article investigated student–university alignment of different dimensions as predictors of psychological adjustment of international students at universities in Victoria, Australia. The results of structural equation modeling suggested student–university goal alignment was positively associated with student psychological adjustment. A revealing finding of this article is the mediating role of complementary fit in the relationship between supplementary fit and student psychological adjustment, where the complementary fit was represented by the alignment between student needs and university academic and facilities support, and supplementary fit was represented by student–university goal alignment. The findings have implications for universities and practitioners in developing the necessary resources to support international students.
Legal Framework for the Education of Individuals With Disabilities in Mexico
Authors: Sanchez Marisol , Valero Chávez Aída Imelda , O’Donnell Matthew D. , Pérez Ramírez Berenice , Ochoa Theresa A.
Published: October 2020

Mexico has general education and disability laws that guarantee special education services to children and adolescents with disabilities as part of their basic human rights. As youth with psychosocial disabilities, such as depression and anxiety, are not recognized within the special education system as a separate category, in practice, they are excluded from educational supports in public schools. Despite laws that state that special education services must be available in all settings, including juvenile prisons, adolescents with psychosocial disabilities lack access to educational programs and properly trained personnel. This article describes Mexico’s special education legal provisions, noting that adolescents with psychosocial disabilities do not receive the same educational services mandated for students in general education.
Risk Factors for Complications Associated With Minimally Invasive Medial Displacement Calcaneal Osteotomy
Authors: Coleman Michelle M. , Abousayed Mostafa M. , Thompson John M. , Bean Bryan A. , Guyton Gregory P.
Published: October 2020

Background:

Few studies have reported the outcomes following minimally invasive medial displacement calcaneal osteotomy (MDCO) for correction of pes planovalgus deformities.

Methods:

Charts were retrospectively reviewed for consecutive patients who underwent minimally invasive MDCO procedures by a single surgeon from 2013 to 2019 with more than 3 months of follow-up. A total of 160 consecutive patients who underwent 189 minimally invasive MDCO procedures were included in the study. Median follow-up was 12 months (interquartile range, 7-25 months).

Results:

Osteotomy healing complications were present in 7% of cases during the 6-year study period. A 12-month case cluster of osteotomy healing complications was observed. Healing complication rates were 28% during the cluster and 0.7% outside of the cluster. No definitive cause was found for the case cluster, although heat osteonecrosis from the burr was suspected to be involved. Osteotomy healing complications were significantly associated with higher American Society of Anesthesiologists (ASA) classification, female sex, current tobacco use, and higher body mass index (BMI). Healing complications were not associated with osteotomy technique or fixation type. Other complications included wound dehiscence (3%), surgical site infection (2%), transient nerve symptoms (6%), and persistent nerve symptoms (2%). Nerve symptoms were significantly associated with an increased number of concomitant procedures.

Conclusion:

Patients with higher ASA classification, current tobacco use, and higher BMI were at higher risk for osteotomy healing complications after minimally invasive MDCO procedures. Patients were also more likely to develop nerve complications with more extensive surgical procedures.

Level of Evidence:

Level IV, retrospective case series.
Robust Distance Measures for kNN Classification of Cancer Data
Authors: Ehsani Rezvan , Drabløs Finn
Published: October 2020

The k-Nearest Neighbor ( kNN) classifier represents a simple and very general approach to classification. Still, the performance of kNN classifiers can often compete with more complex machine-learning algorithms. The core of kNN depends on a “guilt by association” principle where classification is performed by measuring the similarity between a query and a set of training patterns, often computed as distances. The relative performance of kNN classifiers is closely linked to the choice of distance or similarity measure, and it is therefore relevant to investigate the effect of using different distance measures when comparing biomedical data. In this study on classification of cancer data sets, we have used both common and novel distance measures, including the novel distance measures Sobolev and Fisher, and we have evaluated the performance of kNN with these distances on 4 cancer data sets of different type. We find that the performance when using the novel distance measures is comparable to the performance with more well-established measures, in particular for the Sobolev distance. We define a robust ranking of all the distance measures according to overall performance. Several distance measures show robust performance in kNN over several data sets, in particular the Hassanat, Sobolev, and Manhattan measures. Some of the other measures show good performance on selected data sets but seem to be more sensitive to the nature of the classification data. It is therefore important to benchmark distance measures on similar data prior to classification to identify the most suitable measure in each case.
Writing with the bitches
Authors: Huopalainen Astrid
Published: October 2020

Could the everyday affective relationships that we share with our animal companions inspire us to think, write and even care ‘differently’ in the field of organisation studies? In this paper, I suggest that organisational scholars have plenty to learn from post-qualitative writing and the posthumanist practice of feminist dog-writing. Drawing from literature on posthumanism, humanimal relations and post-qualitative methodology, I first frame feminist dog-writing as a practice that relies on post-qualitative writing and discuss what this framing potentially involves, in concrete terms. Second, I experiment with ‘writing with the bitches’ to illustrate how this kind of writing ‘differently’ – in ways in which the entangled co-becoming of the humanimal is highlighted in its multiplicity – could contribute to discussions of humanimal relations in the field of organisation studies and more disruptive, post-qualitative forms of writing in our scholarly field. Despite the many challenges of anthropocentric language and representation, I argue that feminist dog-writing has the capability to creatively confuse, disrupt, and transform more ‘conventional’, mechanical, and hu man-centred forms of academic writing. Finally, I suggest that feminist dog-writing invites human animals to engage differently with the sensate, more-than-human life-worlds that human-centred accounts of organisational life have typically sentimentalised, trivialised, or overlooked.
Of longing and waiting: An inter-Asia approach to love and intimacy among older lesbians and bisexual women
Authors: Tang Denise T-S
Published: October 2020

This paper examines same-sex intimacies formed by and among older Chinese lesbians and bisexual women who were born from the late 1930s to the late 1950s through qualitative interviews and participant observation conducted in Hong Kong, Singapore and Taiwan. For this paper, I aim at complicating cultural notions of love, romance and intimacies, that were brought up within interstices of connected histories, gender roles and marginalized sexual subjectivities. Based on ethnographic data collected during 2016–2018, I elaborate on the moments of longing and waiting as redefining modern notions of love and intimacy across time and spatial dimensions. Then I bring up a methodological episode where inter-Asian referencing intersects with Chinese modernities to illustrate how gender and sexuality meet, intersect and influence each other in the cultural imagination and eventual materialization of women’s same-sex desires. The last section will examine the politics of butchness as protection and as a form of politeness.
‘Hang on, she just used that word like it’s totally easy’: Encountering ordinary racial affects in early childhood education and care
Authors: Tembo Shaddai
Published: October 2020

At a time when racism remains prevalent in educational spaces, this paper addresses what else we can know about the ways in which race and racism manifest and are experienced in practice. This paper draws on continual mobilisations of affect and new materialist theory to examine the conditions of emergence through which race and racism are experienced within ordinary, yet affective, encounters. I propose that drawing attention to how race surfaces in affective encounters may allow us to develop more critical interventions that challenge racisms in process.

Published: October 2020

The energy storage efficiency is an important performance of a robot or a man–machine interaction device. This article will introduce the process of design and energy storage research of a variable stiffness elastic actuator with a two-elements and one actuator mod. Firstly, the principle model will be present to analyze the operation theory. Then, the simulation and experiment model will be described to calculate the characteristics of the device. The stiffness ratio of the two springs constituting the elastic element of the device will be studied in detail, and the results can present the rule of the energy storage value. Finally, the performance of the device, the error of the experiment, and a special mechanism which presented at the extreme shape condition of the ratio will be discussed. The conclusion is that the maximum energy that the device can store is 1.415 J at the stiffness ratio equaling 0.46, and the energy storage efficiency is 1.3608 at the ratio equaling 0.45, when the weight of the device is 3.54 kg and the apparent stiffness is about 3450 N/m.
Follow-up evaluation of the Coaching for Life Skills online training program
Authors: Turgeon Stéphanie , Camiré Martin , Rathwell Scott
Published: October 2020

Coach education has been positioned as an important catalyst in enabling coaches to maximise the positive influence of high school sport on student-athlete development. The purpose of the study was to conduct a subsequent season follow-up evaluation, examining longer-term changes in coach-athlete relationship, coach interpersonal behaviours, and life skills teaching in coaches who completed the Coaching for Life Skills (CLS) online training program. A 2 × 2 prospective causal comparative design was used. Coaches ( n = 285) were asked to complete follow-up measures during the high school sport season that followed their completion of the trial. The response rate was 36.84%, with the final sample consisting of 64 participants. Data were analysed using independent sample t-tests. From baseline to subsequent season follow-up, scores for coach-athlete relationship and coach interpersonal behaviours significantly increased for the CLS group and significantly decreased for the comparison group. No significant differences in scores were found on life skills teaching from baseline to subsequent season follow-up. The results suggest that the intervention may have helped CLS group coaches remain consistent in their use of relational coaching behaviours.

Published: October 2020

Aims:

Switching from originator to biosimilar is part of current practice in inflammatory rheumatic musculoskeletal diseases (iRMDs) such as rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondylarthritis (axSpA), with evidences derived from both etanercept (ETN) to SB4-switching randomized controlled trials and real-life registries. We investigated the safety and treatment persistence of ETN/SB4 in a multi-iRMD cohort derived from two rheumatology departments in our region.

Methods:

Adult patients with iRMDs, treated with ETN for at least 6 months and switched to SB4 in stable clinical condition, were eligible for this retrospective evaluation. Retrospective data on adverse events, loss of efficacy and persistence on treatment were collected until latest available follow-up.

Results:

A total of 220 patients (85 RA, 81 PsA, 33 axSpA, 14 juvenile idiopathic arthritis and seven other conditions; 142 females, mean age 58 ± 7 years, disease duration 12 ± 4 years, ETN duration 7 ± 4 years) were enrolled, with median follow-up of 12.1 (9.7–15.8) months. A total of 50 patients (22.7%) presented with at least one adverse event, with 36 (16.4%) disease flares and 30 (13.6%: 11 for safety and 19 loss of efficacy) SB4 withdrawals. Cumulative SB4 treatment persistence was 99.1%, 88.6% and 64.6% at 6, 12 and 18 months respectively. Back-switch to ETN was performed in 17/30 cases, the remaining cases were managed with change of biologic disease modifying or conventional synthetic anti-rheumatic drug. Age was the only significant predictor of SB4 interruption at 6 months.

Conclusion:

Our real-life data confirm the safety profile of switching from ETN to SB4, with slightly higher treatment persistence rates compared with other real-life registries.
Energy efficiency of a flat-plate solar collector using thermally treated graphene-based nanofluids: Experimental study
Authors: Alawi Omer A , Kamar Haslinda Mohamed , Mohammed Hussein A , Mallah AR , Hussein Omar A
Published: October 2020

A covalent functionalization approach was utilized for the preparation of highly dispersed pentaethylene glycol-thermally treated graphene-water as the absorbing material inside a flat-plate solar collector. Four mass fractions of nanofluids were prepared (0.025, 0.05, 0.075, and 0.1 wt% pentaethylene glycol-thermally treated graphene-water). Graphene nanoparticles were characterized by energy dispersive X-ray analysis with a scanning electron microscope. Measurements of the thermophysical properties were subsequently carried out for the nanosuspensions. The raw investigation data were collected from an indoor flat-plate solar collector test setup. The experimental procedure included different sets of variables such as input temperatures of 303, 313, and 323 K; fluid mass flow rate of 0.00833, 0.01667, and 0.025 kg s−1; and heat flow density of 500, 750, and 1000 W m−2. The thermophysical tests of pentaethylene glycol-thermally treated graphene-water nanofluids showed a proportional increase against weight concentrations, while the specific heat power was reduced. The tests showed an increment in energy efficiency by increasing the fluid mass flow rate and heat input. By comparison, the thermal efficiency decreased with the increasing temperature of the fluid supply. Relative to the base fluid, the energy efficiency of pentaethylene glycol-thermally treated graphene/water-based flat-plate solar collector increased to 10.6%, 11%, and 13.1% at the three fluid mass flow rates. In conclusion, an exponential form was used to derive the thermal effectiveness of flat-plate solar collector based on the experimental data.
The Rural–Urban Fringes in the Local Limelight: Urban Village Redevelopment in Yinchuan, Ningxia
Authors: Malzer Michael
Published: October 2020

As urbanisation strategies have been adopted throughout China in recent years, it has become increasingly relevant to study their implementation processes in so-called lower-tier cities away from the well-known regions. Urbanisation has given rise to different types of settlements for landless peasants: planned resettlement neighbourhoods, as well as more or less accidentally grown urban villages. While resettlement is widely adopted and positively propagated, urban villages are usually only seen as soon-to-be demolished “non-places” and their residents are often stigmatised. This article focuses on a case in Yinchuan, the capital of Ningxia Hui autonomous region. It analyses the demolition process of Yingnan village and its lead-up and finds that despite this general discursive framework, exposure on a local TV show and low scores on a national “civilised cities” ranking pressured the local government to not ignore Yingnan village as merely a “non-place” but to invest in better sanitary conditions and speed up redevelopment.
Social and Economic Political Ideology Consistently Operate as Mutual Suppressors: Implications for Personality, Social, and Political Psychology
Authors: Costello Thomas H. , Lilienfeld Scott O.
Published: October 2020

Right–left political views can be decomposed into distinct economic and social dimensions that bear differing relations with external criteria. In three community samples (total N = 1,487), we identified replicable suppressor situations in which statistically controlling for either social or economic political ideology increased the other ideology dimension’s relations with variables reflecting cognitive rigidity, authoritarianism, dangerous worldview, and lethal partisanship. Specifically, positive bivariate relations between social conservatism and these outcomes were enhanced after controlling for economic conservatism, whereas, after controlling for social conservatism, positive bivariate relations between economic conservatism and external criteria became negative and negative bivariate relations were enhanced. We identified similar, albeit less consistent, suppressor phenomena for general personality. Taken together, our results suggest that social and economic conservatism differ substantially in their psychological implications, and that following statistical control, these differences emerge in samples in which social and economic conservatism are highly positively correlated.
Oral Ulceration: An Overview of Diagnosis and Management
Authors: Thakrar Priya , Chaudhry Shahid I
Published: October 2020

Mouth ulcers are a common complaint by patients, with individuals regularly presenting to primary care practitioners for diagnosis and treatment. The aetiology and pathogenesis of oral ulceration is, however, both varied and complex. This article highlights the importance of differentiating recurrent aphthous stomatitis (RAS) in otherwise healthy individuals from recurrent oral ulceration (ROU) secondary to known or unknown systemic disease. An overview of the diagnosis and management of such patients is provided as a framework to guide general dental practitioners’ with clinical decision making on whether to treat or refer to secondary care.
Prevention and Management of Tooth Wear: The Role of Dental Technology
Authors: Green James Ij
Published: October 2020

Tooth wear is a multifactorial condition and the term is used to describe all types of non-carious tooth substance loss: abrasion (produced by interaction between the teeth and other substances), attrition (produced during tooth-to-tooth contact), erosion (produced by a chemical process) and abfraction (produced through abnormal occlusal loading that predisposes tooth substance to mechanical and chemical wear). Dental technology has an important role in preventing, managing and monitoring tooth wear in a variety of ways. Hard poly(methyl methacrylate) or soft ethylene-vinyl acetate splints can be prescribed to alleviate bruxism, the most common cause of attrition. Thermoformed appliances can be used for the application of products that reduce dental erosion such as fluoride gel. Patients with significant tooth surface loss may require laboratory-made restorations, as well as removable appliances with bite planes that generate inter-occlusal space to facilitate restorations, or surgical templates to provide guidance in preparing restorations for those requiring surgical crown lengthening. Dental study models and digitised models can also prove valuable in terms of monitoring the condition. This paper presents a review of the role that dental technology plays in tooth wear prevention, management and monitoring.
Facts and Fallacies About Restorative Philosophies for the Management of the Worn Dentition
Authors: Kelleher Martin G. , Blum Igor R.
Published: October 2020

This article addresses facts and fallacies about managing worn teeth and challenges some traditional concepts and beliefs about occlusion. Whilst it is accepted that many of the historic occlusal concepts were well intended, closer examination reveals that many were unnecessarily destructive of sound tooth tissues and did not deliver all of their purported benefits. Those fallacies make them less appropriate in the litigious environment of contemporary dental practice. This paper discusses the disadvantages of ‘subtractive’ dental procedures for the management of tooth wear, and highlights the benefits of proven minimally destructive ‘additive’ techniques.
Managing Edentate Older Adults
Authors: Srinivasan Murali , Schimmel Martin , Leles Claudio , McKenna Gerry
Published: October 2020

Whilst increasing numbers of older people retain natural teeth, a sizable proportion of older people are still edentate. Replacement of missing teeth is important for function, aesthetics and to facilitate social interactions. The process of providing oral rehabilitation for edentate older adults can be challenging, but clinicians can utilise a number of treatment options including removable or implant retained prostheses. In this article, complete denture construction will be described using both conventional and copy denture techniques. Recent innovations in the process for constructing complete dentures using computer aided design and manufacturing (CAD-CAM) techniques will also be discussed. Dental implants can be used to help retain removable complete prostheses for edentate patients and the use of implant-retained overdentures is presented as a treatment alternative.

Published: October 2020

Improvements in oral health including increased retention of natural teeth have given rise to a partially dentate older population. Replacement of missing natural teeth is important to improve function, aesthetics and quality of life for this patient group. A variety of options are available to replace missing teeth in partially dentate older adults, including fixed, removable and implant retained prostheses. This article will discuss the provision of removable partial dentures including treatment planning and denture design. When planning removable partial dentures, careful attention must be paid to stabilising the patient prior to delivering any prosthesis. Partial dentures should be designed to minimise the potential for plaque accumulation with carefully designed metal based frameworks. Acrylic resin can also be utilised with attention to detail to minimise the risk of damage to delicate supporting tissues. Removable dentures have the advantage that they can be readily added to in the event of further tooth loss which may be particularly relevant for older adults. Partial dentures which optimise support, retention and stability can function very successfully and significantly improve patients’ oral health related quality of life.
Managing Patients at Risk of Medication Related Complications Requiring Dental Extractions in Primary Care

Published: October 2020

When undertaking dental extractions in modern dental practice, two of the complications that have the potential to cause most apprehension for clinicians are the risks of osteonecrosis of the jaws and uncontrollable haemorrhage. This is especially the case when treating older patients because of the increased likelihood of co-morbidities and accompanying polypharmacy which can predispose patients to these problems. Specific medications of concern to practitioners in relation to osteonecrosis risk are antiangiogenic and antiresorptive drugs. Patients taking dual antiplatelet therapy and direct oral anticoagulants require consideration in relation to bleeding risk. With these medications coming increasingly to the forefront over recent years, guidance has been developed by organisations such as the Scottish Dental Clinical Effectiveness Programme (SDCEP). Appropriate use of these guideline should ensure that patients felt to be at particular risk of these complications can frequently be safely managed in primary care. This article aims to provide advice on recognising patients at risk, and to discuss how to utilise key messages within published guidelines when making treatment decisions. The overall intent is to help primary care clinicians who are likely to encounter these patients more and more.

Introduction and Purpose

Geriatric patients, who are fed by nasogastric tube (NG), may suffer from complications. Therefore, this study was conducted to evaluate the effect of abdominal massage on Gastric residual volume (GRV), distension, vomiting, and defecation in geriatric patients, who were hospitalized in intensive care unit and fed by NG.

Methods

The quasi-experimental study was conducted in intensive care units. The researcher applied abdominal massage to patients in the intervention group (n = 30) twice a day for 15–20 minutes before feeding. The data of the study were collected by using a questionnaire and a parameter questionnaire.

Results

GRV decreased significantly in the intervention group and increased significantly in the control group ( p < 0.05). The frequency of defecation significantly increased in intervention group ( p < 0.05). It was found that there was no positive effect of abdominal massage on vomiting ( p > 0.05).

Conclusion

It was observed that while abdominal massage reduced high GRV and distension incidence, it increased the incidence of defecation.

Background

Integrated steelmaking is known to emit coarse airborne ‘nuisance’ dust (10–100 µm) to the production site and in the local environs. We present a method to quantitatively analyse the provenance, mineralogical and chemical attributes of the constituent particles in nuisance dust related to the integrated steelworks of Tata Steel, IJmuiden, the Netherlands. The dust is characterised per particle, using scanning electron microscopy with energy-dispersive spectrometry (SEM–EDS) microanalysis, and in bulk with quantitative X-ray diffraction (XRD) analysis. Based on mineralogical characteristics, particles in the dust are sorted into populations that can be related in detail to industrial processes and subsequent atmospheric weathering influence. The method is illustrated by application to a nuisance dust complaint sample from the neighbouring town Wijk aan Zee containing a large contribution of several dust sources from the integrated steelworks.

Results

Besides a background contribution from urban and natural dust, diverse sources from the integrated steelworks are identified in the nuisance dust sample, derived from coke-making, iron-ore agglomeration processes and blast furnace ironmaking, steelmaking slag processing, process fluxes, as well as steelmaking refractory materials. The most voluminous of these in the sample are directly verified by comparison with a set of reference source materials. The abundances, mineralogical and chemical attributes of the various dust particle populations in the sample are quantitatively examined including, specifically, the occurrence of the potentially toxic elements Mn and V. These elements occur with highest concentrations in dust derived from steelmaking converter slag: V is housed in dilute form (solid solution) in the phases di-calcium silicate and brownmillerite, and Mn chiefly in Mg–Fe-oxide (Mg-wustite ((Mg,Mn,Fe)O) and its oxidation product ((Mg,Mn,Fe)(Fe,Mn)2O4)).

Conclusions

By treating nuisance dust as a particulate, multi-phase, multi-source material, the outlined method provides crucial information for toxicological evaluation and for mitigation of emissions, which is not obtainable by bulk chemical analyses alone. It also helps address the lack of adequate monitoring options for deposits of nuisance dust from integrated steel production, necessary to evaluate the relationship between deposition and monitored emissions that are regulated by the European Industrial Emissions Directive and by local permits based on this legislation.

Background

Increasing evidence indicates that the pathology and the modified Kadish system have some influence on the prognosis of esthesioneuroblastoma (ENB). However, an accurate system to combine pathology with a modified Kadish system has not been established.

Methods

This study aimed to set up and evaluate a model to predict overall survival (OS) accurately in ENB, including clinical characteristics, treatment and pathological variables. We screened the information of patients with ENB between January 1, 1976, and December 30, 2016 from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) program as a training cohort. The validation cohort consisted of patients with ENB at Sun Yat-sen University Cancer Center and The First Affiliated Hospital of Sun Yat-sen University in the same period, and 87 patients were included. The Pearson’s chi-squared test was used to assess significance of clinicopathological and demographic characteristics. We used the Cox proportional hazards model to examine univariate and multivariate analyses. The model coefficients were used to calculate the Hazard ratios (HR) with 95% confidence intervals (CI). Prognostic factors with a p-value < 0.05 in multivariate analysis were included in the nomogram. The concordance index (c-index) and calibration curve were used to evaluate the predictive power of the nomogram.

Results

The c-index of training cohort and validation cohort are 0.737 (95% CI, 0.709 to 0.765) and 0.791 (95% CI, 0.767 to 0.815) respectively. The calibration curves revealed a good agreement between the nomogram prediction and actual observation regarding the probability of 3-year and 5-year survival. We used a nomogram to calculate the 3-year and 5-year growth probability and stratified patients into three risk groups.

Conclusions

The nomogram provided the risk group information and identified mortality risk and can serve as a reference for designing a reasonable follow-up plan.
