To be able, or disable, that is the question: A critical discussion on how language affects the stigma and self-determination in people with parability
Authors: Mousavi S. Bentolhoda , Lecic-Tosevski Dusica , Khalili Hassan , Mousavi S. Zeinab
Published: April 2020

Background:

Despite several fruitful attempts in destigmatization, disability is still associated with stigma. The role of language, especially when addressing a disabling condition and people, has been the matter of social as well as scientific debates. This article poses an intriguing question about the language we apply when addressing people and disability.

Method:

A narrative review of different models of disability with the emphasis on how labels and more generally language affect identity formation, and the extendibility of positive psychology concepts on the field of disability studies.

Results:

In this theoretical paper, the authors suggest that the term disability per se is contributing to increasing the stigma and has disempowering effect. Considering previous evidence from different lines of literature, the authors suggest a new approach of destigmatization, namely changing the term disability to a less stigmatizing one. Moreover, the authors discuss some theories to support this perspective.

Conclusion:

Replacing ‘dis’ in ‘disability’ with the prefix ‘para’ in the term ‘Para-ability’ is suggested.
On the Impossibility and Inevitability of Monsters in Biblical Thought
Authors: Paffenroth Kim
Published: April 2020

After general considerations of what constitutes a “monster,” this essay examines the examples of “monsters” in the Bible, showing that the Bible does not as frequently depict such beings as do other mythologies. The implications of this for understanding the biblical outlook on creation in general are considered, leading to the conclusion that in fact, in the Bible, it is God who is a monster, or at least, on the side of monsters, and is not to be relied on to eradicate them.
Constructing Imperial and National Identities: Monstrous and Human Bodies in Book of Watchers, Daniel, and 2 Maccabees
Authors: Portier-Young Anathea
Published: April 2020

Monster theory illuminates the construction of imperial and national identities in the portrayals of monstrous and human bodies in three early Jewish texts; Book of Watchers, Daniel, and 2 Maccabees. Book of Watchers expresses anxiety about Judean/Jewish identity in the shadow of empire through its portrayal of a vulnerable humanity terrorized by voracious giants and their demonic spirits. Daniel dehumanizes empire and its agents, imaging empire as a colossal statue, an animalistic were-king, and a series of monstrous beasts, while one like a human being poses an alternative to imperial rule. Second Maccabees, by contrast, demythologizes, decapitates, dismembers, and disintegrates the imperial body in order to portray the integral Judean political body (and soul) as mature, pure, capable, and ordered.
In the Eye of the Storm: Rebel Taxation of Artisanal Mines and Strategies of Violence
Authors: Krauser Mario
Published: April 2020

According to the resource curse theory, persistent violence in developing areas results from rebels’ ability to finance warfare with natural resource revenues. Surprisingly, this overlooks the complexities of raising revenue from a mobile mining population that values security as well as income. The literature thus neglects a fundamental question: what are the incentives of rebel groups to prevent or perpetuate conflict in mining areas? This paper delineates a rational to both increase and decrease violence. Protecting a mine should allow rebels to extract taxes in return. Simultaneously, to maintain this demand for security, rebels may need to destabilize the wider area. The hypotheses are tested with novel data on rebel taxation at over 3’000 artisanal mines in the eastern Democratic Republic of the Congo. Supporting the hypotheses, the results show that rebel-taxed mines appear exempt from violence nearby but imperiled at the perimeter.
Smoke and Mirrors: The Recreational Marijuana Debate
Authors: Millea Timothy P.
Published: April 2020

The increasingly widespread legalization of recreational marijuana should raise concerns regarding the societal and medical impact of its use. The relative cultural acceptance for its use should be counterbalanced with an honest and scientific review of the adverse impacts. This article provides a synopsis of recent studies that point to significant concerns from medical and psychiatric viewpoints.

With the increasing number of states that have legalized the use of recreational marijuana, concerns regarding its negative effects are necessary. There is growing scientific evidence that the use of marijuana for recreational purposes has a wide variety of negative health effects, both physical and psychiatric.
Theological Studies and the Reception of Vatican II
Authors: O’Collins, SJ Gerald
Published: April 2020

This study begins with articles that appeared in Theological Studies during Vatican II and concerned the making of three conciliar documents. It then investigates the reception of the Council in the pages of Theological Studies: the first twenty years (1966–85); the ensuing decades (1986–2011); the fifty-year celebrations (2012–15) and their immediate aftermath. The Extraordinary Synod of 1985 gave a fresh impetus to research and writing about Vatican II. This article examines major contributions to the reception of the Council that appeared in Theological Studies and came from such scholars as Avery Dulles, John O’Malley, Francis Sullivan, and Jared Wicks. Theological Studies has done much toward receiving Vatican II and continues to do so.
The World at Risk: Vulnerability, Precarity, and Connectedness
Authors: Keenan James F.
Published: April 2020

This article considers the world at risk; in particular it focuses on the three topics covered at the international conference of Catholic Theological Ethics in the World Church in 2018 in Sarajevo: climate change, its impact on marginalized populations, and the tragic banality of contemporary political leadership. The article turns to a proposal by Trinity College’s Linda Hogan to develop an ethics of vulnerability so as to respond to the triple crisis. After examining contemporary writings on both vulnerability and precarity by Judith Butler and others, it concludes by applying the ethics of vulnerability to other urgent cases as well.
Fifty Years of International Catholic–Lutheran Dialogue: Much Consensus, Little Fellowship?
Authors: Tjørhom Ola
Published: April 2020

This article presents an overview and an assessment of the international Catholic–Lutheran dialogue through fifty years. During the process, a theological rapprochement that few had dreamt of when the work began has been manifested. In the text Facing Unity (1984), even a detailed plan for a processual realization of Catholic–Lutheran church fellowship is sketched. However, this plan has not been implemented, and the achieved doctrinal convergence has not been transformed into concrete forms of unity. The author also seeks to uncover some of the main causes of this impasse, largely reflecting challenges in contemporary ecumenism.
Detection of Item Preknowledge Using Response Times
Authors: Sinharay Sandip
Published: April 2020

Benefiting from item preknowledge is a major type of fraudulent behavior during educational assessments. This article suggests a new statistic that can be used for detecting the examinees who may have benefited from item preknowledge using their response times. The statistic quantifies the difference in speed between the compromised items and the non-compromised items of the examinees. The distribution of the statistic under the null hypothesis of no preknowledge is proved to be the standard normal distribution. A simulation study is used to evaluate the Type I error rate and power of the suggested statistic. A real data example demonstrates the usefulness of the new statistic that is found to provide information that is not provided by statistics based only on item scores.
Working with Infrastructural Communities: A Material Participation Approach to Urban Retrofit
Authors: Johnson Charlotte , Bell Sarah , Borrion Aiduan , Comber Rob
Published: April 2020

Retrofit is a rising area of concern for Science and Technology Studies (STS) scholars of infrastructure. This paper sits at the junction between applied and theoretical approaches by using STS to support interventions in urban infrastructure systems and expand STS critique of retrofit. It discusses findings from a multidisciplinary project piloting retrofit possibilities to positively impact the way water, energy, and food resources were consumed in a London housing estate. Through qualitative research, we found that residents were making social and material interventions in infrastructure systems to manage the way resources were consumed at home, driven by a commonly held motivation to avoid wastefulness. We then mapped the social and material factors that helped or hindered these individual ambitions and used them to inform our codesign process. We found it helpful to think of the residents as an infrastructural community; a group of residents that share a material connection that can help mobilize collective action on shared consumption. We suggest this concept is useful for interventions and critiques of infrastructure retrofit, particularly in cities in the Global North where retrofit programs aim to rescale national systems to neighborhood levels. The concept highlights the possibilities for participation that emerge from bottom-up retrofit.

Published: April 2020

The present study investigated (1) how social relationships with teachers and peers and self-esteem of students with social–emotional and behavioral difficulties (SEBD) in inclusive regular education (regular schools) and students with SEBD in exclusive special education (special schools) develop over time in comparison with each other and in comparison with their typically developing peers and (2) whether factors—present before students with SEBD received special education services—predicted social–emotional development in either educational setting. Thirty-six students with SEBD in regular schools, 15 students with SEBD in special schools, and 1,270 typically developing peers participated. We collected data when students with SEBD resided in regular education without additional support, and we followed the development of students with SEBD for 1.5 years with three additional measurements in either school setting. Data of typically developing peers were collected when they resided in a classroom of a participating student with SEBD. Using Bayesian statistics, we found that students with SEBD in special schools had more conflictual relationships with their teachers than typically developing peers, but these relationships improved over time. Students with SEBD in regular schools were less accepted among peers than typically developing students and peer acceptance was stable over time for all three groups. Self-esteem and development in self-esteem over time did not differ between groups. The current study shows that students with SEBD show different developmental trajectories in regular or special schools and that it is difficult to predict their social–emotional development by factors present before students with SEBD received special education services.
The struggle and (im)possibilities of decolonizing Latin American citizenship practices and politics in Toronto
Authors: Cahuas Madelaine C
Published: April 2020

This paper explores the tensions racialized migrants negotiate when politically organizing and enacting citizenship within the context of the Canadian white settler state. I focus on the experiences of Latin Americans in Toronto and the politics surrounding a cultural celebration – Hispanic Heritage Month. While some Latin Americans sought to use this event to gain recognition and assert their belonging to Canadian society, others opposed its naming, objectives and organization, and opted to create an alternative celebration – the Latin-America History Collective’s Día de la Verdad/Day of Truth Rally. I demonstrate that the narratives and practices mobilized around Hispanic Heritage Month and Latin-America History Collective’s Rally reveal how different forms of migrant political organizing can internalize, reproduce and contest white settler colonial social relations. Overall, this paper aims to contribute to and complicate debates on the fraught nature of racialized migrants’ citizenship, politics and identity formation in Canada, by emphasizing the vast heterogeneity of Latin American communities and decolonizing possibilities.
Performance calibration among youth with visual impairment on a 6-minute endurance run test
Authors: Kirk TN , Haegele Justin A , Zhu Xihe
Published: April 2020

Physical activity and fitness have long been associated with health, yet youth with visual impairments tend to be less active and less fit than their sighted peers. Performance calibration (i.e., the degree to which predictions about performance reflect actual performance) may be a useful conceptual framework to investigate the relationships between perceptions of health-related fitness and measured fitness performance among youth with visual impairments. The purpose of this study was to examine the predictive and postdictive performance calibration of youth with visual impairments on a test of cardiovascular fitness. Twenty-five participants (12 female, 13 male, aged 10–17 years) completed a 6-min endurance run test. Before and after the test, participants estimated how far they would run. Based on these data, performance calibration scores were calculated, and variables were correlated. Gender and visual impairment level-based differences were compared using t tests. Participants were generally overconfident in their predicted run scores but underconfident in their postdictions. Results of the present study suggest that youth with visual impairments are generally poorly calibrated with regard to cardiovascular fitness.
Personal Values and Consumers’ Ethical Beliefs: The Mediating Roles of Moral Identity and Machiavellianism
Authors: Chowdhury Rafi M. M. I.
Published: April 2020

This study constitutes a theoretically grounded exploration of the factors that mediate the relationship between consumer values and ethical beliefs. An online survey of US consumers was conducted to explore potential mediators of the effects of personal values on consumers’ ethical beliefs. The results show that moral identity and dimensions of Machiavellianism (amoral manipulation, desire for control) mediate the effects of self-transcendence orientation (the importance of self-transcendence values relative to that of self-enhancement values) and conservation orientation (the importance of conservation values relative to that of openness-to-change values) on beliefs about unethical consumer actions. Furthermore, moral identity mediates the effects of self-transcendence orientation and conservation orientation on beliefs about pro-social actions. These results demonstrate that personal values, moral character, and belief systems all influence consumer ethics. Macromarketing implications for public policy, particularly education policy, are discussed.
Design, implementation, and control of a deformable manipulator robot based on a compliant spine
Authors: Morales Bieze Thor , Kruszewski Alexandre , Carrez Bruno , Duriez Christian
Published: April 2020

This article presents the conception, the numerical modeling, and the control of a dexterous, deformable manipulator bio-inspired by the skeletal spine found in vertebrate animals. Through the implementation of this new manipulator, we show a methodology based on numerical models and simulations, that goes from design to control of continuum and soft robots. The manipulator is modeled using a finite element method (FEM), using a set of beam elements that reproduce the lattice structure of the robot. The model is computed and inverted in real-time using optimization methods. A closed-loop control strategy is implemented to account for the disparities between the model and the robot. This control strategy allows for accurate positioning, not only of the tip of the manipulator, but also the positioning of selected middle points along its backbone. In a scenario where the robot is piloted by a human operator, the command of the robot is enhanced by a haptic loop that renders the boundaries of its task space as well as the contact with its environment. The experimental validation of the model and control strategies is also presented in the form of an inspection task use case.
Modeling and analysis of soft robotic fingers using the fin ray effect
Authors: Shan Xiaowei , Birglen Lionel
Published: April 2020

Soft grasping of random objects in unstructured environments has been a research topic of predilection both in academia and in industry because of its complexity but great practical relevance. However, accurate modeling of soft hands and fingers has proven a difficult challenge to tackle. Focusing on this issue, this article presents a detailed mathematical modeling and performance analysis of parallel grippers equipped with soft fingers taking advantage of the fin ray effect (FRE). The FRE, based on biomimetic principles, is most commonly found in the design of grasping soft fingers, but despite their popularity, finding a convenient model to assess the grasp capabilities of these fingers is challenging. This article aims at solving this issue by providing an analytic tool to better understand and ultimately design this type of soft fingers. First, a kinetostatic model of a general multi-crossbeam finger is established. This model will allow for a fast yet accurate estimation of the contact forces generated when the fingers grasp an arbitrarily shaped object. The obtained mathematical model will be subsequently validated by numerically to ensure the estimations of the overall grasp strength and individual contact forces are indeed accurate. Physical experiments conducted with 3D-printed fingers of the most common architecture of FRE fingers will also be presented and shown to support the proposed model. Finally, the impact of the relative stiffness between different areas of the fingers will be evaluated to provide insight into further refinement and optimization of these fingers.
Geometric constraint-based modeling and analysis of a novel continuum robot with Shape Memory Alloy initiated variable stiffness

Published: April 2020

Continuum robots exhibit promising adaptability and dexterity for soft manipulation due to their intrinsic compliance. However, this compliance may lead to challenges in modeling as well as positioning and loading. In this paper, a virtual work-based static model is established to describe the deformation and mechanics of continuum robots with a generic rod-driven structure, taking the geometric constraint of the drive rods into account. Following this, this paper presents a novel variable stiffness mechanism powered by a set of embedded Shape Memory Alloy (SMA) springs, which can make the drive rods become ‘locked’ on the body structure with different configurations. The resulting effects of variable stiffness are then presented in the static model by introducing tensions of the SMA and friction on the rods. Compared with conventional models, there is no need to predefine the actuation forces of the drive rods; instead, actuation displacements are used in this new mechanism system with stiffness being regulated. As a result, the phenomenon that the continuum robot can exhibit an S-shaped curve when subject to single-directional forces is observed and analyzed. Simulations and experiments demonstrated that the presented mechanism has stiffness variation of over 287% and further demonstrated that the mechanism and its model are achievable with good accuracy, such that the ratio of positioning error is less than 2.23% at the robot end-effector to the robot length.

Authors: Wang Xiaoting , Hu Shouzi , Ji Wenbin , Tang Yan , Zhang Shulong
Published: April 2020

Objective

To identify genes associated with the clinicopathological features of colorectal cancer (CRC).

Methods

Gene expression profiles were downloaded and preprocessed by GEOquery and affy R packages, respectively. The limma package was applied to identify the differentially expressed genes (DEGs) in CRC. Gene Ontology and Kyoto Gene and Genome Encyclopedia (KEGG) pathway enrichment analyses for the DEGs were carried out using the clusterProfiler package. Protein–protein interaction (PPI) and weighted gene co-expression (WGC) networks were constructed using the STRING database and WGCNA package, respectively.

Results

A total of 523 DEGs (283 downregulated and 240 upregulated genes) in CRC tissues were identified. These DEGs were mainly enriched in 111 biological processes, 16 cellular components and 40 molecular functions, such as proteinaceous extracellular matrix, extracellular structure organization and chemokine-mediated signalling pathway. PPI and WGC networks showed that four upregulated genes ( KIF2C, CDC45, CEP55 and DTL) were key genes. Subgroup analysis based on individual cancer stages and histological subtypes indicated that the expression of these key genes was upregulated in CRC stages I–IV, adenocarcinoma and mucinous adenocarcinoma.

Conclusions

The study provides new insights into understanding the pathogenesis of CRC. These identified genes may act as potential targets for CRC diagnosis and treatment.
Effects of Transient and Nontransient Changes of Surface Feature on Object Correspondence
Authors: Jiang Hao
Published: April 2020

Object correspondence is a fundamental problem in perception. Classic theories hold that the computation of correspondence is solely based on spatiotemporal information. Recent research showed that surface features also play an important role. However, the surface features of objects in many studies did not change throughout a trial. This study investigated the effect of feature change on object correspondence using the object-reviewing paradigm. Two moving objects underwent transient feature changes on color dimension (Experiment 1A) or a combination of three dimensions (Experiment 2A). Moreover, the objects moved behind four occluders to make the feature change nontransient (Experiments 1B and 2B). Object-specific preview benefits were reduced or eliminated when feature changes were transient, but the benefits were not affected when feature changes were nontransient. The effects of transient versus nontransient changes of surface feature in object correspondence are discussed.
‘Kindred Without End’: Wet-Nursing, Fosterage and Emotion in Ireland, c. 1550–1720
Authors: Tait Clodagh
Published: April 2020

Wet-nursing and fosterage were widely used in early modern Ireland. Despite the difficulties of reconstructing practices surrounding the nourishment and care of infants and young children, the limited surviving sources provide some evidence for the practical arrangements involved, the role of these practices in extending families and creating long-lasting ties of ‘fictive kinship’, the emotional and economic connections they forged and deeply held concerns that they might inspire and extend political disloyalty and disaffection. While fosterage is mostly associated with Gaelic communities, by the sixteenth century, a distinct brand of fosterage was significant to Old English families as well. New English and Protestant families also increasingly participated in networks referred to as fosterage, and references in the 1641 depositions testify to the degree to which these practices linked settlers and natives and the horror inspired by their abandonment.
Comparison of an industrial- and a laboratory-scale furnace for analysis of hydrocarbon intumescent coating performance
Authors: Zeng Ying , Weinell Claus Erik , Dam-Johansen Kim , Ring Louise , Kiil Søren
Published: April 2020

Due to increasing demands for fire protection in high-risk environments, such as petrochemical processes and offshore platforms, so-called hydrocarbon intumescent coatings are increasingly used to protect structural steel in the event of a hydrocarbon fire. For these coatings, the fire-resistance performance is typically evaluated in a series of costly experiments with industrial-scale (i.e. 1–10 m3) furnaces, programmed to follow a standard hydrocarbon fire test curve. In this work, we propose a laboratory-scale furnace for coating evaluation, which can simulate the conditions of a typical hydrocarbon fire curve, that is, the standard UL 1709. In a case study with five hydrocarbon intumescent coating formulations, the correlation between the laboratory- and the industrial-scale furnace was investigated and a good agreement was found for the temperature progression of the coated steel plates. The physical and chemical properties of the intumescent coating chars were also similar for the two furnaces. In summary, the low-cost, time-efficient laboratory-scale furnace can provide reliable screening of hydrocarbon intumescent coatings and is recommended as a complementary tool for industrial fire tests.
In vitro genotoxicity assessment and comparison of cerium (IV) oxide micro- and nanoparticles
Authors: Arslan Kader , Akbaba Giray Buğra
Published: April 2020

Cerium (IV) oxide (CeO2), which is used as a biomaterial, has wide application in areas such as the biomedical, glass polishing, electronic, automotive, and pharmacology industries. Comparing with the literature, in this study, the genotoxic effects of cerium (IV) oxide microparticles (COMPs) and cerium (IV) oxide nanoparticles (CONPs) were investigated for the first time in human peripheral blood cultures at concentrations of 0.78, 1.56, 3.125, 6.25, 12.5, 25, and 50 ppm for 72 h under in vitro conditions. Particle sizes of COMPs and CONPs were determined using scanning electron microscopic analysis. Micronucleus and chromosome aberration tests were used to determine the genotoxicity of COMPs and CONPs. The average particle sizes of COMPs and CONPs were approximately 148.25 and 25.30 nm, respectively. It was determined that CeO2 particles in both micro and nano sizes were toxic at all concentrations compared to the negative control group (distilled water). Importantly, COMPs and CONPs were genotoxic even at the lowest concentration (0.78 ppm). Comparing particle sizes, the data indicated that COMPs were more toxic than CONPs. The results suggest that genotoxicity of COMPs and CONPs may be a function of applied concentrations and particle sizes.
An opportunity for improved engagement and transparency: A systematic review of renal dialysis cost effectiveness and discrete choice experiment studies
Authors: Heenan Michael
Published: April 2020

Much attention is given to patient and provider engagement, cost, and quality. Nephrology is in a unique position to examine the intersection of these issues given kidney dialysis is delivered at a high cost to chronically ill patients. Annual dialysis treatments in Canada range from $56,000-$107,000 per patient dependent on modality. Economists quantify the preferred modality by calculating cost effectiveness through quality-adjusted life years or determining utilization through Discrete Choice Experiments (DCEs). Cost-effectiveness studies identify peritoneal dialysis as the most economical, yet it is the least used. Discrete choice experiments address patient preferences but rarely include cost attributes. This presents a unique paradigm: cost studies do not include patient or physician perspectives, and DCEs do not consider cost. This systematic review of dialysis cost-effectiveness studies and DCEs identifies an opportunity to increase engagement and transparency by involving all care partners in assessing quality and cost.
Vasopressor and Inotrope Therapy in Cardiac Critical Care
Authors: Jentzer Jacob C. , Hollenberg Steven M.
Published: April 2020

Patients admitted to the cardiac intensive care unit (CICU) are often in shock and require hemodynamic support. Identifying and addressing the pathophysiology mechanisms operating in an individual patient is crucial to achieving a successful outcome, while initiating circulatory support therapy to restore adequate tissue perfusion. Vasopressors and inotropes are the cornerstone of supportive medical therapy for shock, in addition to fluid resuscitation when indicated. Timely initiation of optimal vasopressor and inotrope therapy is essential for patients with shock, with the ultimate goals of restoring effective tissue perfusion in order to normalize cellular metabolism. Use of vasoactive agents for hemodynamic support of patients with shock should take both arterial pressure and tissue perfusion into account when choosing therapeutic interventions. For most patients with shock, including cardiogenic or septic shock, norepinephrine (NE) is an appropriate choice as a first-line vasopressor titrated to achieve an adequate arterial pressure due to a lower risk of adverse events than other catecholamine vasopressors. If tissue and organ perfusion remain inadequate, an inotrope such as dobutamine may be added to increase cardiac output to a sufficient level that meets tissue demand. Low doses of epinephrine or dopamine may be used for inotropic support, but high doses of these drugs carry an excessive risk of adverse events when used for vasopressor support and should be avoided. When NE alone is inadequate to achieve an adequate arterial pressure, addition of a noncatecholamine vasopressor such as vasopressin or angiotensin-II is reasonable, in addition to rescue therapies that may improve vasopressor responsiveness. In this review, we discuss the pharmacology and evidence-based use of vasopressor and inotrope drugs in critically ill patients, with a focus on the CICU population.
Physical Abuse of Children by Stepfathers in Colombia
Authors: Nobes Gavin , Panagiotaki Georgia , Malvaso Catia , Klevens Joanne
Published: April 2020

Evolutionary psychologists claim that stepparents perpetrate substantially more child physical abuse than genetic parents, and that they do so because they are less invested in genetically unrelated children. The objective of this study was to examine these claims by investigating whether, and why, fathers in a Colombian sample physically abused their stepchildren more than their genetic children. Fathers ( N = 86) and their partners living in Bogotá were interviewed by Klevens et al. Half of the fathers had been reported to authorities for child physical abuse, the other half were matched controls. Secondary analysis was conducted of Klevens et al.’s data. Hypotheses from the evolutionary and ecological accounts of child maltreatment were tested using logistic and ordinal regression. Both the prevalence and the frequency of physical abuse by stepfathers were considerably greater than those of genetic fathers. Several indicators of adversity—including parental youth and experience of abuse, fathers’ chronic stress, and mothers’ poor communication with the child—were associated with both abuse and stepparenthood. Models including these variables indicated that they accounted for much of the stepfathers’ higher rates of abuse. Consistent with the ecological account, much of the stepfathers’ greater prevalence and frequency of abuse in this sample is likely to have resulted from confounding variables, rather than from the step relationship per se.
The Ties That Bind: Britain’s Use of Scottish Highland Dress
Authors: Loranger David , Sanders Eulanda A.
Published: April 2020

For over 300 years, Britain has influenced Scotland’s national identity. Scottish Highland dress, which consists of kilts and tartans has been appropriated, manipulated, and transformed by the British in order to forward political, commercial, and social objectives. Scotland’s national dress has contributed to a more cohesive identity within the United Kingdom. However, available research only examines specific instances of British influence on—and usage of—kilts and tartans. The purpose of this study was to identify and explore a sample of key figures and historical events that illustrate the use of Scottish Highland dress to forward British interests. The researchers triangulated databases and secondary literature along with extant objects and materials, with the aim of developing a more holistic understanding of appropriation, manipulation, and transformation. Findings indicate how the context and usage of Scottish Highland dress was transformed over time.

Authors: Wong Ben Jin , Majumdar Ketav , Ahluwalia Kunal , Yeo Swee-Hock
Published: April 2020

Previous work on vibratory finishing has led to a better understanding and establishment of the mass finishing processes. Despite the sustained efforts made to date, vibratory finishing remains a field where the findings made have been based largely on empirical evidence. Through force sensor analyses and scanning electron microscopy imaging, in this work a successful attempt has been made in uncovering the underlying science—through first principles of Newtonian physics—behind vibratory finishing, providing explanations for the observations made. Trials were carried out in a high-frequency vibratory bowl, the first of its kind in the vibratory finishing industry. Through these trials, mathematical formulations have been derived, essentially providing a reliable way for the industry to estimate the process cycle time.
Tool tip cutting specific energy prediction model and the influence of machining parameters and tool wear in milling
Authors: Zhao Guoyong , Su Yu , Zheng Guangming , Zhao Yugang , Li Chunxiao
Published: April 2020

Most of the existing energy-consumption models of machine tools are related to specific machine components and hence cannot be applied to other machine tools with different specifications. In order to help operators optimize machining parameters for improving energy efficiency, the tool tip cutting specific energy prediction model based on machining parameters and tool wear in milling is developed, which is independent of the standby power of machine tools and the spindle no-load power. Then, the prediction accuracy of the proposed model is verified with dry milling AISI 1045 steel experiments. Finally, the influence of machining parameters and tool wear on tool tip cutting specific energy is studied. The developed model is independent of machine components, so it can reveal the influence of machining parameters and tool wear on tool tip cutting specific energy. The tool tip cutting specific energy reduces with the increase in the cutting depth, side cutting depth, feed rate, and cutting speed, while increases linearly as the tool wears gradually. The research results are helpful to formulate efficient and energy-saving processing schemes on various milling machines.
Laser cutting optimization model with constraints: Maximization of material removal rate in CO2 laser cutting of mild steel
Authors: Madić Miloš , Mladenović Srđan , Gostimirović Marin , Radovanović Miroslav , Janković Predrag
Published: April 2020

Taking full advantage of what laser cutting technology offers in terms of achieving superb quality cuts at low cost and high production rates requires the optimization of laser cutting parameters. This implies the need to formulate and solve different laser cutting optimization problems. In this article, an optimization model for CO2 laser cutting of mild steel is developed. The laser cutting optimization problem was explicitly formulated as a single-objective optimization problem with five non-linear constraints of the equality, inequality and range type. The goal was to determine the laser cutting parameter values so as to maximize the material removal rate while simultaneously considering practical process constraints related to dross formation, kerf width, perpendicularity deviation, surface roughness and severance energy. Two crossed experimental designs of different resolutions were performed in order to define six mathematical models, which were used in the formulation of the optimization problem. For the purpose of optimization, the exhaustive iterative search algorithm was applied, since it determines solutions whose optimality is guaranteed in the given discrete space of input variable values. The practical usability of the developed laser cutting optimization model and the effectiveness of the applied optimization approach were proved while solving a real case study aimed at the optimization of laser cutting parameters for cutting parts for the furnace industry.

Authors: Yu Jianqiang , Dong Xiaomin , Wang Xuhong , Li Junli , Li Biao
Published: April 2020

This research investigates the design, modeling, and control of an improved magnetorheological rotary damper for seat suspension. A magnetorheological damper with optimized flux path is developed to improve the distribution of magnetic field. Its dynamic damping characteristics are tested by MTS machine under sinusoidal excitations. To describe the nonlinear damping characteristics of magnetorheological damper, a hysteretic model based on backbone curve is selected by comparing with other models. To verify the feasibility of seat suspension with the proposed magnetorheological damper, the simulated analysis and experimental tests are conducted. A dynamic model of scissor seat suspension with rotary damper is constructed and simplified. The performances of semi-active system show that the seat suspension with the proposed damper can reduce vibration efficiently.
Modelling the patient accrual with truncated Gaussian mixture distribution for the accurate estimation of sample size in survival trials
Authors: Hu Haixia , Wang Ling , Li Chen , Ge Wei , Wu Kejian , Xia Jielai
Published: April 2020

In survival trials with fixed trial length, the patient accrual rate has a significant impact on the sample size estimation or equivalently, on the power of trials. A larger sample size is required for the staggered patient entry. During enrollment, the patient accrual rate changes with the recruitment publicity effect, disease incidence and many other factors and fluctuations of the accrual rate occur frequently. However, the existing accrual models are either over-simplified for the constant rate assumption or complicated in calculation for the subdivision of the accrual period. A more flexible accrual model is required to represent the fluctuant patient accrual rate for accurate sample size estimation. In this paper, inspired by the flexibility of the Gaussian mixture distribution in approximating continuous densities, we propose the truncated Gaussian mixture distribution accrual model to represent different variations of accrual rate by different parameter configurations. The sample size calculation formula and the parameter setting of the proposed accrual model are discussed further.
Do We Become More Prosocial as We Age, and if So, Why?

Published: April 2020

Older adults contribute—through charitable donations or volunteering—more to the common good than younger adults, an age difference that has profound society-level implications. Yet the reasons for this difference are not well understood. Evidence suggests that a purely altruistic concern for the common good is a major motivation for prosocial behavior and that this concern increases across adulthood. We argue that this finding, and prosocial behavior in general, is better understood using a value-based decision framework than through traditional dual-process accounts. Following the value-based decision approach, we derive specific hypotheses about life-span changes in motivation or resources as factors that explain why older adults show an increased concern for the well-being of other people.
Misread and mistaken: Étienne Lancereaux’s enduring legacy in the classification of diabetes mellitus
Authors: Wright James R , McIntyre Lynn
Published: April 2020

Historians of diabetes have long claimed that physicians were aware of two distinct types of diabetes mellitus by the 1880s, and that these were the direct forerunners of type 1, juvenile-onset and type 2, adult-onset diabetes. French physician Étienne Lancereaux (1829–1910), based on autopsy and clinical studies, classified diabetes either as diabète maigre (thin, or more accurately emaciated, diabetes), which he believed to be pancreatic in origin with a poor prognosis, or diabète gras (fat diabetes), which he believed had a much better prognosis and was not pancreatic in origin. Historians citing Lancereaux have claimed that he observed the former to occur in young and the latter in middle-aged and elderly people. We review the papers of Lancereaux to clarify his clinical observations and understanding of diabetes. Lancereaux’s description of diabète maigre bores little resemblance to juvenile diabetes and all of his thin patients were middle-aged or older. On the other hand, his diabète gras is akin to type 2 diabetes and he might well deserve credit for its characterization.
Spirituality in nursing: A concept analysis
Authors: Murgia Carla , Notarnicola Ippolito , Rocco Gennaro , Stievano Alessandro
Published: April 2020

Background:

Spirituality has always been present in the history of nursing and continues to be a topic of nursing interest. Spirituality has ancient roots. The term ‘spirituality’ is interpreted as spirit and is translated as breath and soul, whereas spirituality (immateriality) is spiritual nature. Historically, the term spirituality is associated with the term religiosity, a definition that persists today, and often the two terms are used interchangeably. In the healthcare context, the construct is still.

Objective

To clarify the concept of spirituality in nursing.

Research design

In this article spirituality was explored using Rodgers' evolutionary and inductive method of concept analysis.

Participants and research context

For this analysis, a sample of 71 articles published in English, from 2008 to 2018 from PubMed/Medline, CINAHL Plus with full text, PsycINFO, SciELO databases were retrieved. It was also accomplished an empirical search of dictionaries and e-books.

Ethical considerations

This study was conducted according to good scientific practice.

Findings

It emerged that “spirituality” is a dynamic process and has a range of attributes. The cultural dimensions, the religious and spiritual traditions, the ethnic diversity and the influence of the historical and social contexts represent the societal and historical conditions ingrained in the Western thought that influence the emergence of spirituality as a concept. Antecedents, attributes and onsequences appeared to inform and strengthen one another over time. Spirituality is a significant concept for the discipline of nursing with profound consequences for caring patients and for work organizations.
Generalist Palliative Care in the California Safety Net: A Structured Assessment to Design Interventions for a Range of Care Settings
Authors: Anderson Wendy G. , Parrish Monique , Kerr Kathleen , Kinderman Anne , Rabow Michael , Schoen Melissa , Meyers Kate
Published: April 2020

Background:

To provide high quality care to all patients who have serious illness, health-care systems must develop effective generalist palliative care strategies.

Objective:

To identify palliative care quality gaps within a range of settings in the California safety net and to develop theory-based interventions to address them.

Design:

Structured assessment using the National Consensus Project for Quality Palliative Care Clinical Practice Guidelines and a Predisposing, Reinforcing, and Enabling Constructs in Educational/Environmental Diagnosis and Evaluation intervention planning model-based worksheet, which integrates behavior theories to identify factors that predispose, enable, and reinforce clinicians to perform recommended behaviors.

Setting and Participants:

Adviser pairs—one from palliative care and one from a partner service line—from 10 California public health-care systems conducted assessments at their sites. A steering committee provided educational webinars, best practices, and assessment tools.

Measurements:

Adviser pairs interviewed at least 6 partner service line stakeholders to identify palliative care quality gaps, behaviors clinicians should perform to close gaps, and factors that predispose, enable, and reinforce those behaviors.

Results:

Partner service lines were primary care (n = 4), surgery (n = 3), emergency department (n = 2), and radiation oncology (n = 1). Selected gaps were advance care planning and goals of care communication (n = 6), identifying patients with serious illness (n = 3), and pain management (n = 1). All sites designed multiple interventions to address gaps, based on factors that predispose, enable, and reinforce a target audience to perform a target behavior. Advisers reported that the program strengthened relationships between palliative care and the partner service line

Conclusion:

This structured assessment helped busy clinicians develop theory-based generalist palliative care interventions.
A model for supporting the ideas screening during front end of the innovation process based on combination of methods of EcaTRIZ, AHP, and SWOT
Authors: Huang Zhe , Ahmed Cherifi , Mickael Gardoni
Published: April 2020

Product innovation is a fundamental factor for a company or even the economy of a country to maintain survival, growth, and long-term success. All innovations begin with creative ideas; however, all the ideas are not the source of an opportunity. Ideas should therefore be carefully evaluated and selected from a wide range of creative ideas using appropriate evaluation methods. This article summarizes seven evaluation methods, discusses the basic principles of the different methods, analyzes their advantages and application advice, and proposes an idea screening process model based on the combination of the EcaTRIZ, analytic hierarchy process (AHP), and SWOT, for supporting the ideas screening during fuzzy front end of the innovation process.
Primary Mammary-Analogue Secretory Carcinoma of the Lung: A Rare Entity With an Unusual Location
Authors: Ramos Josean , Mahmud Waqas , Ocampo Fernando Alekos , Alex Gillian , Gattuso Paolo
Published: April 2020

This is a case of a 55-year-old female with past medical history of tobacco smoking, hypertension, and lupus who presented with a left lung nodule, found on computed tomographic scan of the chest during workup for a recently diagnosed squamous cell carcinoma in a cervical lymph node. Resection of the lung nodule showed a 2.3-cm well-defined pale-tan mass, and histologic examination showed a well-circumscribed lesion with papillary, solid, and gland-like architectural patterns, with eosinophilic secretions, areas of comedonecrosis, and increased mitotic activity. Immunohistochemical stains showed the lesion to be positive for cytokeratin 7, S100 protein, and focally positive for mammaglobin. Fluorescence in situ hybridization studies confirmed rearrangement of the ETV6 gene at 12p13.2. To date, our case is the second reported case of a primary mammary-analogue secretory carcinoma arising in the lung, and the first to show evidence of tumor necrosis: an unusual feature in an unusual location.
