Medically Unexplained Physical Symptoms: Why Counseling Psychologists Should Care About Them
Authors: McAndrew Lisa M. , Friedlander Myrna L. , Litke David R. , Phillips L. Alison , Kimber Justin M. , Helmer Drew A.
Published: December 2019

Medically unexplained symptoms and/or syndromes (MUS) affect the health of 20% to 30% of patients seen in primary care. Optimally, treatment for these patients requires an interdisciplinary team consisting of both primary care and mental health providers. We propose that counseling psychologists may develop expertise to improve the care of patients with MUS who are already in their practice, expand the number of patients they help, and enhance the integration of counseling psychology into the broader medical community. Additionally, counseling psychologists’ expertise in culture, attunement to therapeutic processes, and focus on prioritizing patients’ perspectives and quality of life can fill the gap in research on MUS. By focusing on MUS, counseling psychologists can provide unique contributions to health service delivery.
Ideology Matters: College Students’ Emotional Reactions to the Killing of Trayvon Martin
Authors: Blackmon Sha’Kema M. , Neville Helen A. , Jones Thomas Anita
Published: December 2019

Building on previous theory and research, we explored the associations among race, intergroup ideologies and emotional reactions to the killing of Trayvon Martin and the acquittal of George Zimmerman among 298 Black and White college students. We also examined the indirect effect of ethnocultural empathy on the links between race, intergroup ideologies, and emotional responding. Using latent class analysis, we identified three latent intergroup ideological classes: Racial Hierarchy-Enhancing Ideology, Universal Hierarchy-Enhancing Ideology (i.e., above sample mean color-blind racial ideology and or social dominance orientation) and Critical Reflection Attenuating Ideology (i.e., above sample mean critical consciousness). Membership in the Critical Reflection Attenuating Ideology group was associated with greater prosocial emotional responding as compared to the two hierarchy-enhancing latent groups. Finally, ethnocultural empathy had an indirect effect on the links between race, latent intergroup ideological classes, and emotional responding.

Published: December 2019

High school students in accelerated classes face heightened school-related stressors but have access to few specialized supports. This article describes the development and initial application of the Motivation, Assessment, and Planning (MAP) intervention, developed to meet the needs of freshmen in Advanced Placement (AP) and International Baccalaureate (IB) curricula. MAP is grounded in motivational interviewing and designed to evoke behavior change following one to two individual meetings with a coach. This study used a multimethod, multisource approach to evaluate the applicability and acceptability of MAP as a Tier 2 support for 9th-grade students completing AP/IB coursework. Quantitative and qualitative acceptability data from 49 AP/IB students, 7 coaches, and 3 potential end-users of MAP were examined. Results indicate MAP was perceived as an acceptable intervention for addressing the social–emotional needs of high-achieving students taking AP/IB classes. Findings and directions for further research of MAP are discussed.
‘Top-Down’ Pronunciation Teaching Revisited
Authors: Pennington Martha C.
Published: December 2019

The concept of ‘top-down’ pronunciation teaching is revisited after 30 years, when my article ‘Teaching Pronunciation from the Top Down’ was published by RELC Journal. The notion of ‘top-down’ teaching of pronunciation is reviewed as presented in the original article and then reconsidered in the light of matters of identity, multilingualism, imitation and empathy, and contextualized teaching of pronunciation.
Shrinking cities: Implications for planning cultures?
Authors: Pallagst Karina , Fleschurz René , Nothof Svenja , Uemura Tetsuji
Published: December 2019

Various institutional and cultural settings have shaped spatial planning systems with comparable features; however, such systems have been adapted to specific cultural, normative and spatial conditions. In line with the growing demand for international knowledge exchange in urban and regional planning, planning cultures have recently come into sharper focus. Moreover, it has become widely acknowledged that many cities in Europe and the USA have to deal with challenges posed by long-term demographic and economic changes. This also holds true for Japan. The objective of the research presented here is to comparatively investigate changes in planning cultures in view of shrinking cities in the USA, Germany and Japan. The findings will allow us to detect interdependencies between changes in planning cultures and societal changes in the wake of shrinkage, and finally to derive hypotheses for both the future-oriented development of shrinking cities, and the development of planning cultures based on the comparison of cultural settings. In this respect the paper concludes with the hypothesis that there might be planning cultures that are not framed by geographic entities (nations, regions, cities), but rather by topics along shrinking cities. This could offer insight into a new research sphere of ‘topical planning cultures’. While lasting effects and successes of policies and strategies applied in shrinking cities remain to be seen, their influence on a broader knowledge exchange, contextualisation and innovation in the sphere of planning cultures is evident.
The complexity of diversity in reality: Perceptions of urban diversity
Authors: Nielsen Rikke Skovgaard , Winther Anne Hedegaard
Published: December 2019

Major cities are becoming increasingly diverse, and the different aspects of diversity interact in shaping individual lives and neighbourhoods. However, existing research mainly presents the urban population living with this diversity as one group with the same overall perception of diversity. The purpose of this article is to nuance the concept of diversity through analysing the differences in urban residents’ perceptions of neighbourhood diversity and the factors shaping these perceptions. The article is based on 50 qualitative interviews with residents of Bispebjerg, one of the most diverse neighbourhoods of Copenhagen, Denmark. The overall finding is that living with diversity is a diverse experience. The article identifies five ideal types of residents to demonstrate how perceptions of diversity are being shaped. They all express a positive perception of diversity on an abstract level but voice concerns regarding concrete aspects of diversity. The article identifies key factors shaping these concrete perceptions of diversity: insecurity towards ethnic diversity; social inequality; degree of socialisation to diversity; and physical and social detachment from diversity. The findings point to the importance of acknowledging differences between perceptions of diversity for different groups of residents and of addressing the different concerns of these groups.
Bargaining power in apartment sales in Corsica: A latent class approach
Authors: Caudill Steven , Detotto Claudio , Prunetti Dominique
Published: December 2019

This paper extends the bargaining model of Harding et al. (Harding J, Rosenthal S and Sirmans CF (2003) Estimating bargaining power in the market for existing homes, Review of Economics and Statistics 85: 178–188), to a latent class framework. This allows for differences in market power in thin and segmented markets. We estimate a latent class model using data on apartment sales in Corsica over the period 2006 to 2016. Our results indicate that the Corsican housing market has two distinct segments or regimes and that bargaining power of buyers and sellers is not the same in these two segments. In particular, we find that local French residents have strong bargaining power in Regime 1 but non-French residents have weak bargaining power. Regime 2 is characterised by strong bargaining power for local French, Corsican French and non-French participants. Based on auxiliary regressions and a comparison of weighted means associated with each regime, we conclude that compared with Regime 2, the apartments associated with the first regime are more spacious, less likely to be new, more likely to have a garden and typically have longer travel times to local amenities such as doctors, pharmacies and the downtown area. From this we conclude that apartments associated with Regime 1 are more likely to be rural and at a greater distance from the coast. Distance from a city is likely to present an informational disadvantage to non-French residents, who may already face language and legal obstacles.
Detecting “White Flight” in the Contemporary United States: A Multicomponent Approach
Authors: Kye Samuel H. , Halpern-Manners Andrew
Published: December 2019

Measuring the existence and patterning of white flight (WF) using aggregate data has a long history in the social sciences. In this article, we assess past measurement approaches and identify several technical and conceptual limitations. To address these shortcomings, we propose a new multicomponent approach to detecting WF that requires tracts to exceed a minimum level of loss across four distinct dimensions of population change. Using both simulated and real data, we show that our approach provides stronger protection against common classification errors and behaves more consistently across a broad range of neighborhood types. We conclude with a substantive application that demonstrates the utility of our multicomponent approach to researchers who are interested in assessing the “buffering hypothesis.” We find that our multicomponent approach detects higher levels of WF than recognized in previous studies, raising important questions about the formation and long-term stability of racially diverse neighborhoods in the United States.
A Meta-analysis of the Relative Effectiveness of the Item Count Technique Compared to Direct Questioning
Authors: Li Jiayuan , Van den Noortgate Wim
Published: December 2019

This article presents an updated meta-analysis of survey experiments comparing the performance of the item count technique (ICT) and the direct questioning method. After synthesizing 246 effect sizes from 54 studies, we find that the probability that a sensitive item will be selected is .089 higher when using ICT compared to direct questioning. In recognition of the heterogeneity across studies, we seek to explain this variation by means of moderator analyses. We find that the relative effectiveness of ICT is moderated by cultural orientation in the context in which ICT is conducted (collectivism vs. individualism), the valence of topics involved in the applications (socially desirable vs. socially undesirable), and the number of nonkey items. In the Discussion section, we elaborate on the methodological implications of the main findings.
Home grown: the development and structure of urological training in the Caribbean
Authors: Persaud Satyendra , Douglas Lawson , Aiken William , Morrison Belinda , Goetz Lester
Published: December 2019

Training in general surgery at the University of the West Indies commenced in Jamaica in 1972 and urology training followed just over a decade later. Since then, the ‘Doctor of Medicine’ diploma offered by the university has also expanded to include the Trinidadian campus. Most urologists in the English-speaking Caribbean are, in fact, graduates of this programme. Residents follow a two-part training plan and two years of core surgical training are followed by four years of urology training. Despite the tremendous regional impact of this training programme, there is a lack of awareness of its existence among the wider urology community. This article reviews the history, development and structure of urology training in the English-speaking Caribbean.
Double Ring in Cochlear Otosclerosis: A Limit to Cochlear Implantation? The Solution Is the Surgical Approach
Authors: Messineo Daniela , Ralli Massimo , Greco Antonio , Arianna Di Stadio
Published: December 2019

We present a case of a 50-year patient with a severe form of otosclerosis (double ring) that was successfully implanted. We used a bone-anchored hearing implant for restoring the hearing in the right side and a cochlear implant in the left side; both surgeries did not show any complications. For reducing the risk of a secondary bone ossification related to the trauma of cochleostomy for electrode’s insertion, we used a round window approach. The patient recovered a normal auditory threshold and normal speech perception capacity both in silence and noise conditions 1 year after surgery.
Special Issue on Toxicologic Neuropathology of the Peripheral Nervous System: A Special Compendium of Past, Present, and Future Developments in a Neglected Field
Authors: Rao Deepa B. , Bolon Brad , Pardo Ingrid D.
Published: December 2019

Neuropathology of the peripheral nervous system (PNS) is an underappreciated area in toxicologic pathology. Toxicity to nerves and ganglia can result from toxic insults following exposure to environmental, occupational, and industrial chemicals; drugs and biologics; cosmetics and food additives; and even physical agents such as noise. The following introduction provides an overview of this special issue of Toxicologic Pathology on toxicologic neuropathology of the PNS and highlights the range of key topics in this field that are reviewed in this compilation.
Self-complexity and socio-emotional adjustment to a romantic event in early adulthood
Authors: Perry Laura M. , Hoerger Michael , Korotkin Brittany D. , Saks Samantha J. , Duberstein Paul R.
Published: December 2019

Self-complexity, the extent that people experience themselves as having a number of distinct and meaningful social roles, may have implications for young adults’ socio-emotional adjustment to romantic life events. Based on prior research, we hypothesized that participants who reported lower self-complexity would have worse adjustment to a negative event (not having a date on Valentine’s Day) but better adjustment to a positive event (having a date). Participants ( N = 325) completed measures of self-complexity and depression symptom severity at study entry. Approximately a month later, at the end of the day on Valentine’s Day, they completed a measure of emotion-regulation strategies and a reassessment of depression symptom severity. The hypothesized interaction was statistically significant; self-complexity was associated with better emotion-regulation ( R 2 = .15, p < .001) and depression outcomes ( R 2 = .05, p = .001) for non-daters, but worse outcomes for daters. Our findings suggest that self-complexity is related to self-regulation and has implications for adjustment to a range of life events.
Oxygen metabolism MRI – A comparison with perfusion imaging in a rat model of MCA branch occlusion and reperfusion
Authors: Little Philip V , Kraft Sandra E , Chireh Arvin , Damberg Peter , Holmin Staffan
Published: December 2019

The penumbra is sustained by an increased extraction of oxygen (OEF) from blood to brain tissue. Metabolic imaging may improve penumbra specificity when examining stroke patients with wake-up stroke and a long time between admission and symptom onset. We used MRI to examine OEF, and compared the volume of regions with elevated OEF to the volume of regions with perfusion deficit in a M2 occlusion model (M2CAO) with preserved collateral blood flow. OEF was calculated from BOLD MRI examining tissue R2′, with ASL perfusion imaging employed to determine cerebral blood flows (CBF) and volumes. Diffusion imaging was used to identify the ischemic core (IC). Examinations were performed during and after transient M2CAO in rats. The IC-OEF mismatch was significantly smaller than the IC-CBF mismatch during M2CAO. The penumbra OEF was significantly increased during M2CAO, and decreased significantly after reperfusion. The IC-OEF mismatch may provide increased penumbra specificity compared to IC-CBF mismatch regimens. Results strongly indicate the potential of metabolic MRI for thrombectomy patient selection in cases with a long time from symptom onset to admission. Results demonstrate the effectiveness of reperfusion in alleviating metabolic disturbances in ischemic regions, emphasizing fast treatment to achieve significant neurological recovery in stroke patients.
Do professional musicians perceive numerosity illusions differently?
Authors: Pecunioso Alessandra , Agrillo Christian
Published: December 2019

A large body of experimental evidence suggests that long-term musical training has profound consequences on the functional organization of the brain, leading to an improvement of cognitive abilities that are non-primarily involved in music. Here, we tested the hypothesis stating that long-term musical training has effects in the perceptual laws underlying vision. To achieve our goal, we compared the susceptibility of musicians and non-musicians to the Solitaire illusion, an illusion of numerosity based on the Gestalt law of proximity and good continuation. Both groups were observed in a relative (Experiment 1) and an absolute (Experiment 2) numerosity task: the former required an estimation of which array contained more blue dots; the latter required an estimation of the number of blue dots presented. In both experiments, the illusory pattern was presented as well. In control trials, no difference was found between musicians and non-musicians in the overall performance. The two groups were susceptible to the illusion in both experiments, although the musicians in Experiment 2 varied in their susceptibility to the numerosity misperception, perceiving a smaller illusory ratio compared with non-musicians. Based on these results, we suggest that prolonged music training may alter the perceptual laws in visual modality.
Effect of regional skill gaps and skill shortages on firm productivity
Authors: Morris David , Vanino Enrico , Corradini Carlo
Published: December 2019

This paper contributes to the literature on regional productivity, complementing previous education and skill-level perspectives with a novel approach analysing the impact of regional skill gaps and skill shortages. This allows us to reflect the idiosyncratic needs of the regional economic structure better, considering both the demand and supply side of the skills equation in localised labour markets. Controlling for unobserved time-invariant firm-level heterogeneity and other region–industry effects across a longitudinal data set for the period 2008–2014, our analysis reveals a negative direct effect of skill shortages on firm productivity. We further find negative spillover effects for both skill gaps and skill shortages in related industries and proximate regions. Results are also shown to be heterogeneous with respect to agglomeration levels and industrial sectors. Stronger negative effects are found in industries defined by a knowledge-intensive skill base, pointing to the loss of learning effects in the presence of skill deficiencies. Conversely, agglomeration effects appear to moderate the impact of skill deficiencies through more efficient matching in the local labour market. The findings presented thus suggest that policies aimed at improving productivity and addressing the increasing regional productivity divide cannot be reduced to a simple space-neutral support for higher education and skill levels but need to recognise explicitly the presence and characteristics of place-specific skills gaps and shortages.
Implementation of fuzzy, Simos and strengths, weaknesses, opportunities and threats analysis for municipal solid waste landfill site selection: Adana City case study
Authors: Unal Muge , Cilek Ahmet , Guner Esra Deniz
Published: December 2019

The selection of suitable landfill locations for municipal solid waste has become a top priority, especially in developed countries as a result of rapid population growth, unplanned urbanisation, increasing waste production and the limited area available. However, determining the location of landfill sites is a complex decision-making problem for municipalities and depends on social, environmental, technical and economic factors and regulations. In this study, we combined a geographic information system (GIS), multi-criteria decision-analysis techniques and fuzzy logic to determine the best location for landfill sites in Adana, Turkey, in four steps. Firstly, the threshold values and the coefficient weights of 15 criteria, grouped into environmental and socio-economic factors, were determined by a literature review and expert opinion to select suitable landfill locations. Secondly, selection criteria were standardised using fuzzy logic. Thirdly, we assessed the criteria weights based on their effectiveness on the selection of potential landfill sites using the Simos method. According to the weight coefficients, environmental factors are more important than socio-economic factors. Final maps for each criterion were calculated and overlaid by a GIS. As a result, the final suitability results were divided into four discrete categories: very high, high, moderate and low suitability areas, representing 1%, 76%, 17% and 6% of the location options, respectively. Finally, four different alternative areas were identified as being very highly suitable for landfill locations, which were evaluated in detail using a strengths, weaknesses, opportunities and threats analysis. Three key aspects affect the final decision of a landfill site, in decreasing order of importance: environmental protection, minimising the negative impact on urban life quality and economic issues. Consequently, these results can guide decision-makers (ministries, municipalities, planners, etc.) during the selection of suitable landfill sites in both national and international studies.
Ending the Stalemate: Toward a Theory of Anthro-Shift
Authors: Fisher Dana R. , Jorgenson Andrew K.
Published: December 2019

For years, sociologists who study society and the environment have focused on resolving the debate regarding the relationship between economic development and environmental degradation. Studies from a family of critical perspectives tend to find that economic development is antithetical to environmental protection, whereas a suite of more optimistic perspectives has uncovered more hopeful findings. We attempt to resolve these differences by situating this debate within the larger framework of the anthro-shift. The anthro-shift explains how the society-environment relationship changes over time. The theory assumes this relationship is the product of interrelations among the state, market, and civil society sectors. We focus on two distinctive qualities of the anthro-shift: the role risk plays as a pivot for reorienting how society interacts with the natural environment and the multidirectionality of the theory, highlighting how it combines elements of many of the dominant critical and optimistic perspectives into a broader framework.
On Assemblages and Things: Fluidity, Stability, Causation Stories, and Formation Stories
Authors: Rutzou Timothy , Elder-Vass Dave
Published: December 2019

This article conducts a dialogue and creates a new synthesis between two of the most influential ontological discourses in the field of sociology: assemblage theory and critical realism. The former proposes a focus on difference, fluidity, and process, the latter a focus on stability and structure. Drawing on and assessing the work of Deleuze, DeLanda, and Bhaskar, we argue that social ontology must overcome the tendency to bifurcate between these two poles and instead develop an ontology more suited to explaining complex social phenomena by accommodating elements of both traditions. Going beyond DeLanda’s recent work, we argue that a concept of causal types must be used alongside a typology of structures to give us an ontology that can sustain sociology’s need for both formation stories and causation stories. We illustrate the necessity and value of our proposed synthesis by discussing MacKenzie’s recent empirical analysis of a high-frequency trading firm.
Social and Health System Complexities Impacting on Decision-Making for Utilization of Oncology and Palliative Care in an African Context: A Qualitative Study
Authors: Agom David A. , Allen Stuart , Neill Sarah , Sixsmith Judith , Poole Helen , Onyeka Tonia C. , Ominyi Jude
Published: December 2019

Background:

There is a dearth of research focusing on identifying the social complexities impacting on oncology and palliative care (PC), and no study has explored how the health-care system in Nigeria or other African contexts may be influencing utilization of these services.

Aim:

This study explored how social complexities and the organization of health-care influenced the decision-making process for the utilization of oncology and PC in a Nigerian hospital.

Methods:

This qualitative study used an interpretive descriptive design. Data were collected using semistructured interview guides with 40 participants, comprising health-care professionals, patients, and their families. Thematic analysis was conducted to generate and analyze patterns within the data.

Findings:

Three themes were identified: dysfunctional structural organization of the health-care delivery system, service-users’ economic status, and the influence of social networks. The interrelationship between the themes result in patients and their family members decisions either to present late to the hospital, miss their clinical appointments, or not to seek oncological health care and PC.

Conclusion:

This article offers insights into the role of the health-care system, as organized currently in Nigeria, as “autoinhibitory” and not adequately prepared to address the increasing burden of cancer. We therefore argue that there is a need to restructure the Nigerian health-care system to better meet the needs of patients with cancer and their families as failure to do so will strengthen the existing inequalities, discourage usage, and increase mortality.
Effect of design parameters and operational conditions on the motion accuracy of hydrostatic thrust bearing
Authors: Zha Jun , Chen Yaolong , Zhang Penghai , Chen Runlin
Published: December 2019

In this study, the effect of design parameters and operational conditions on motion accuracy of the closed configuration hydrostatic thrust bearing was researched. Key design parameters include land width, nominal oil film thickness, and perpendicularity error between mandrel and thrust plates. Oil supply pressure, external load, and rotation load are the considered operational conditions. Predictions of the induced effect are made by introducing oil film clearance function, governing equations, flow rate continuity equations, and dynamic equations of mandrel to model axial rotation error and angular motion error. The results show that the axial rotation accuracy increased, as land width (larger than 8 mm), nominal oil film thickness, and oil supply pressure increased, but there was little impact on angular motion error. The axial rotation error and angular motion error increased with the increase in the external load and rotation speed. Confirmation of the perpendicularity error has been achieved, in this study, by conducting experiments, using ultra-precision measuring machine. In addition, axial rotation error was tested on a hydrostatic rotary table and compared with the simulation results to check the validity of the proposed method. The results provide useful design guidelines and operation advice for hydrostatic thrust bearing in high-precision machine tools.
Sexually transmitted infection screening and diagnosis among adolescent men who have sex with men, three US cities, 2015

Published: December 2019

Adolescent men who have sex with men (MSM) are at increased risk for sexually transmitted infections (STIs) and HIV; however, data documenting STI screening, STI burden, and associated risk factors for STIs are extremely limited. Using 2015 data from the National HIV Behavioral Surveillance among Young MSM, we examined self-reported STI screening and STI diagnosis of chlamydia, gonorrhea, or syphilis among sexually active adolescent MSM by selected characteristics. Analysis of STI diagnosis was limited to participants who reported an STI screening. Differences in STI screening and STI diagnosis and factors associated with screening and diagnosis were examined using bivariate and multivariable binomial regression models. Less than half of adolescent MSM reported having ever been screened for an STI. Among these, more than a quarter reported having ever been diagnosed with chlamydia, gonorrhea, or syphilis. STI screening was associated with visiting a healthcare provider in the past 12 months and having ever been tested for HIV. Having ever had an STI diagnosis was associated with the participant age of 18 years and having sex before 13 years old. Among adolescent MSM, STI screening was suboptimal and STI burden was significant. STI intervention and prevention programs are urgently needed to promote STI awareness, timely screening, and early diagnosis to interrupt transmission among this vulnerable population.
Adherence to the 2012 European gonorrhoea guideline in the WHO European Region according to the 2018–19 International Union against Sexually Transmitted Infections European Collaborative Clinical Group gonorrhoea survey
Authors: Unemo M , Clarke E , Boiko I , Patel C , Patel R ,   on behalf of the ECCG Core Group
Published: December 2019

Gonorrhoea is a major public health problem globally. Increasing incidence in many particularly developed countries and the emergence of resistance to the extended-spectrum cephalosporin ceftriaxone, the last option for empiric first-line monotherapy, are of serious concern. This paper evaluates the results of the 2018–19 International Union against Sexually Transmitted Infections European Collaborative Clinical Group survey on the diagnosis and treatment of gonorrhoea in Europe. Although high quality clinical care was reported in many European settings, in several countries the testing, diagnostics, antimicrobial treatment, and follow-up of gonorrhoea patients were evidently suboptimal. Increased adherence to evidence-based European and/or nationally-adapted management guidelines is essential in controlling the increasing incidence of gonorrhoea in many European settings and the spread of ceftriaxone-resistant, multidrug-resistant, and extensively drug-resistant gonorrhoea.
Politics of the ‘South’: Discourses and praxis
Authors: Lazar Michelle M.
Published: December 2019

The introduction ‘Politics of the “South”’ refers simultaneously to the thematic focus of the special issue on political discourse studies in the southern hemisphere as well as a theoretical focus on the geopolitics of academic knowledge production and exchange. In the first part, concerns regarding the geopolitics of knowledge in the social sciences generally and linguistics particularly, and the problematic nature of the conceptual categories of the Global ‘South’ and ‘North’ are discussed. Following this, the concept of the ‘South’ as ‘an ex-centric locus of enunciation and praxis’ is advanced, and explained in terms of critical reflexivity and transformation of epistemic attitudes and practices. In the second part, five studies on political discourse analysis from selected areas in the Global South (Taiwan, Thailand, Colombia, Ghana, and Cuba and Mexico) are described through a southern lens. The aim is to highlight what these studies reveal about political discourses and practices in and of the South, as well as how they contribute to the wider knowledge ecology of critical political discourse studies.

Hepatocyte transplantation (HcTx) is a promising approach for the treatment of metabolic diseases in newborns and children. The most common application route is the portal vein, which is difficult to access in the newborn. Transfemoral access to the splenic artery for HcTx has been evaluated in adults, with trials suggesting hepatocyte translocation from the spleen to the liver with a reduced risk for thromboembolic complications. Using juvenile Göttingen minipigs, we aimed to evaluate feasibility of hepatocyte transplantation by transfemoral splenic artery catheterization, while providing insight on engraftment, translocation, viability, and thromboembolic complications. Four Göttingen Minipigs weighing 5.6 kg to 12.6 kg were infused with human hepatocytes (two infusions per cycle, 1.00E08 cells per kg body weight). Immunosuppression consisted of tacrolimus and prednisolone. The animals were sacrificed directly after cell infusion ( n=2), 2 days ( n=1), or 14 days after infusion ( n=1). The splenic and portal venous blood flow was controlled via color-coded Doppler sonography. Computed tomography was performed on days 6 and 18 after the first infusion. Tissue samples were stained in search of human hepatocytes. Catheter placement was feasible in all cases without procedure-associated complications. Repetitive cell transplantations were possible without serious adverse effects associated with hepatocyte transplantation. Immunohistochemical staining has proven cell relocation to the portal venous system and liver parenchyma. However, cells were neither present in the liver nor the spleen 18 days after HcTx. Immunological analyses showed a response of the adaptive immune system to the human cells. We show that interventional cell application via the femoral artery is feasible in a juvenile large animal model of HcTx. Moreover, cells are able to pass through the spleen to relocate in the liver after splenic artery infusion. Further studies are necessary to compare this approach with umbilical or transhepatic hepatocyte administration.
Performance Appraisal and Team Effectiveness: A Moderated Mediation Model of Employee Retention and Employee Satisfaction
Authors: Upadhyay Rajesh Kumar , Ansari Khaliqur Rehman , Bijalwan Pankaj
Published: December 2019

The changing business environment in the service sector requires service providers to adapt to the ongoing changes that incorporate more adaptability with a higher quality of service. Teamwork is an important aspect of working in the service sector as nowadays teamwork is seen as a fitting response to the changes in the business environment. Effective teamwork can help the service organizations to provide better quality service to its customers. The current study is an attempt to highlight the influence of performance appraisal (PA), employee satisfaction (ES) and employee retention (ER) on team effectiveness (TE) in the service sector. The analysis of the data was carried out using statistical tools, like the confirmatory factor analysis, and the structural equation modelling for elucidating the validity of the design. The results of the study show that PA and TE have a significant relation. ER acts as a partial mediator between PA and TE, and, on the other hand, ES acts as a moderator between PA and ER. The article provides key practical implications for the service sector in the state of Uttarakhand.
Introduction to section on values in evaluation praxis
Authors: Boyce Ayesha S
Published: December 2019

There has yet to be consensus within the field on whose and what criteria, or values, should be used to judge program worth. Furthermore, evaluators continue to grapple with decisions about which stakeholder values are to be included in evaluation, and if evaluators should be advocating or prescribing certain values or not. This introduction very briefly highlights the discourse associated with valuing in evaluation and summarizes the four articles in the Values in Evaluation Praxis section.
Stakeholders’ shifting values in an evaluation of a literacy professional development programme
Authors: Kallemeyn Leanne M
Published: December 2019

The author uses her experience as an evaluator for a literacy professional development programme with urban elementary schools in the United States to illustrate failures and successes with negotiating values and value judgements. Values are defined here as ‘the basis of criteria that inform the judgement of merit, worth, or significance of a program’, and value judgements are an assertion regarding the merit, worth or significance of the programme based on a process of weighing the evidence in relation to the value criteria. In the example, the author worked from what Schwandt called a ‘descriptive view of valuing’, to describe the views and experiences of the programme from a variety of perspectives in an effort to guide stakeholders in making value judgements about the programme. The evaluator refrained from being the sole authority that made value judgements and did not assume that prescriptive criteria could be reached among stakeholders. The author offers her reflections on the process as well as discussion questions for readers.
Health assessment of juvenile green turtles in southern São Paulo State, Brazil: a hematologic approach
Authors: de Mello Daniela M. D. , Alvarez Maria C. L.
Published: December 2019

We assessed the health status and hematologic and blood chemistry values of 48 juvenile green turtles ( Chelonia mydas) on the southeastern coast of Brazil (25°S 48°W). We investigated the impact of size and weight, nutritional condition, and presence of epibionts and fibropapilloma tumors. Nutritional status was good for 39 animals; these animals had higher serum albumin, cholesterol, and phosphorus concentrations than 9 animals with a fair nutritional score. Reference values for hematology and biochemistry were calculated for 39 individuals without fibropapillomas (FPs). Turtles with epibionts ( n = 33) had lower hemoglobin (Hb) than turtles without epibionts ( n = 15; t = −2.09, p = 0.04), and the area occupied by epibionts was positively correlated with the white blood cell count ( r = 0.37, p = 0.03). FP turtles had significantly lower hematocrit (Hct), Hb, and red blood cell (RBC) counts than non-FP turtles; serum albumin and cholesterol were higher in non-FP than FP turtles. A negative correlation between curved carapace length (CCL) and Hct ( r = −0.51, p = 0.0002) and RBC ( r = −0.47, p = 0.0007), and between serum cholesterol, sodium, and uric acid and CCL ( r = −0.53, p = 0.0001; r = −0.38, p = 0.007; r = −0.35, p = 0.014, respectively) were identified. The health of turtles appears to deteriorate as they get larger, which manifests in more FPs, decreased body condition, and systemic physiologic changes consistent with chronic disease including lower Hct, RBC counts, serum cholesterol, sodium, and uric acid.

We developed a SYBR green I–based reverse-transcription quantitative PCR (RT-qPCR) assay for bovine ephemeral fever virus (BEFV). Analytical sensitivity of the assay was ~ 100 times higher than conventional RT-PCR. The precision of the RT-qPCR established for RNA standards was high, with intra-assay and inter-assay coefficients of variation of 0.23–0.89% and 0.23–1.02%, respectively. The test was highly specific for BEFV strains, with no cross-reactivity with other viruses of veterinary significance. The assay detected BEFV RNA as early as 1 d post-infection (dpi) and up to 7–8 dpi in the blood samples of experimentally infected cattle. The most stable reference gene, peptidylprolyl isomerase A ( PPIA), was selected for the quantification of BEFV. Viral RNA loads reached peak level at 3–5 dpi and then decreased rapidly through 7–8 dpi. Our assay provides a reliable approach for the detection of BEFV in the early infection stage and for use in the profiling of BEFV kinetics in vivo.
Exploring Diverse Voices in the Classroom
Authors: Liu Chiao-Wei
Published: December 2019

With the increasing diverse student population in the United States, schools across the country face the challenge of addressing cultural diversity in the classroom. While this topic is not new in the field of music education, researchers argue that voices of minoritized groups remain absent in most music programs. Even if different music cultures are introduced, they often reinforce existing racial/ethnic stereotypes. In this column, I would like to share one concept that I found helpful in addressing diversity in the classroom. Through my own work, I learned that the music with which students engage outside the classroom affords rich potential to discuss issues related to diversity. Inviting students to bring in music that matters to them helps them develop their own voices and to recognize and respect different voices, through which we acknowledge the complexity and multiplicity of how diversity plays out in human experiences.

Building from the psychology of working framework, we examined the moderating role of proactive personality in the attainment of decent work among a sample of racially and ethnically diverse employed adults in the United States ( N = 238). We tested our hypotheses using structural equation modeling and found experiences of marginalization and economic constraints to have indirect associations with decent work via work volition. We also found marginalization, work volition, and career adaptability to have direct associations with decent work but found no support for proactive personality as a moderating mechanism. Our findings contribute to the growing literature examining how contextual variables are associated with securing decent work among diverse groups. We discuss practical implications along with future directions for research related to the psychology of working.
Identification of unbalance in a rotor-bearing system using Kalman filter–based input estimation technique
Authors: Shrivastava Akash , Mohanty Amiya R
Published: December 2019

Unbalance is a common machinery fault, which occurs because of uneven distribution of mass of a rotating component about its axis. Vibration-based monitoring techniques have been widely accepted for machinery fault diagnosis. This article presents experimental verification of a recently developed Kalman filter–based method for the identification of unbalance in rotor systems. The method is tested on an experimental test rig for different unbalance configurations and shaft speeds. The proposed technique is a model-based method, which requires a mathematical model of the rotor system along with response measurements. A rigid rotor model is used, and measured accelerations at bearing pedestals are used for unbalance parameter estimation. Bearing stiffnesses are estimated using a frequency domain parameter estimation technique with measured unbalance responses. Sensitivity analysis is also performed by altering the values of these estimated stiffnesses.
Contemporary Indigenous Women’s Roles: Traditional Teachings or Internalized Colonialism?
Authors: Baskin Cyndy
Published: December 2019

Prior to the colonization of Turtle Island, Indigenous women held leadership roles within their communities. Colonization brought patriarchy and racism which attacked women’s identities. Violence toward Indigenous women and girls continues to be a tool of the colonial state while many Indigenous peoples have internalized patriarchal beliefs which manifests in the way they view women’s identities. This article argues that patriarchy may have infiltrated so-called “traditional teachings” that dictate rules about women’s participation in spiritual and cultural practices. It highlights the voices of Indigenous women who discuss this exclusion and how they are taking back their power.
Engaging Customers in Value Co-Creation Through Mobile Instant Messaging in the Tourism and Hospitality Industry

Published: December 2019

Tourism and hospitality service providers have been seeking ways to engage customers in the value creation process to deliver personalized experiences. Such practices have been facilitated by the rapid development of information communication technology. Extant research on online customer engagement focuses mostly on computer-based platforms. Mobile instant messaging (IM) has rarely been explored despite its substantial potential for firm–customer interactions. On the basis of service–dominant logic and computer-mediated communication theories, this study examines customers’ perceived co-creation experience facilitated by mobile IM. It empirically tests the influencing factors and effects of such co-creation experience. The findings extend the theoretical framework of value co-creation to a context mediated by mobile IM. Managerial suggestions are provided for tourism and hospitality organizations.
CNS demyelination after initiating the tyrosine kinase inhibitor imatinib: A report of two cases

Published: December 2019

The tyrosine kinase inhibitor, imatinib, used to treat certain malignancies, is in clinical trials as a potential treatment for multiple sclerosis and acute stroke. This is the first report of cases of multifocal central nervous system (CNS) demyelination following exposure to imatinib. One case was severe with bilateral optic neuritis and transverse myelitis that was AQP4 IgG and myelin oligodendrocyte glycoprotein (MOG) IgG negative and improved after plasma exchange and withdrawal of imatinib. The second case involved a unilateral optic neuritis with magnetic resonance imaging (MRI) brain confirming other demyelinating lesions. Although the mechanism is unknown, demyelination on imatinib could be related to activation of previously normal T-cells.
