Leading school change and improvement
Authors: Kovačević Jasna , Hallinger Philip 
Published: June 2019

PurposeThe purpose of this paper is to quantitatively document and synthesize the knowledge base on leading school change and improvement (LSCI).Design/methodology/approachThe authors employed bibliometric analysis to evaluate 1,613 SCOPUS-indexed documents on LSCI published between 1960 and the end of 2017. In addition to descriptive analysis of basic features of the knowledge base, the review also employed citation and co-citation analyses of authors, journals and documents. Author co-citation analysis (ACA) was used reveal the intellectual structure of the LSCI literature.FindingsThe growth trajectory of LSCI research began with low levels of publication during the 1960s and 1970s, followed by steady and then accelerating growth in subsequent decades. Citation analyses highlighted key journals, authors and documents in this field, while ACA identified four research streams or Schools of Thought that comprise the LSCI knowledge base: transformational leadership for school improvement, instructional leadership for school improvement, shared leadership for change and school improvement, school improvement.Originality/valueThe review offers empirical documentation of the changing intellectual structure of the one of the key lines of inquiry that emerged in the field of educational administration over the past six decades. More broadly, the review illustrates the benefits of bibliometric analysis as a tool capable of illuminating critical features that bear upon knowledge accumulation in a line of inquiry, or a broader discipline.
What influences Chinese fashion retail? Shopping motivations, demographics and spending
Authors: Parker Christopher J. , Wenyu Lu 
Published: June 2019

PurposeThe purpose of this paper is to establish the influence of shopping motivations on Chinese fashion retail engagement relative to demographics, monthly spend on fashion items and high street/electronic commerce (e-commerce) preference. This is to determine how international fashion retailers should design more effective retails channels, expanding upon established theory in Hedonic and utilitarian motivations. While earlier research suggests shopping motivations associate with demographics while influencing retail channel preference and consumer spending, much of this exploration is Western focused, with all variables being influential. However, the degree to which these apply to China, and the unique fingerprint of influential motivations remains unknown. This paper answers these questions to allow international retailers to develop more efficient marketing strategies and design more effective retail channels.Design/methodology/approachIn all, 403 Chinese consumers generalisable to the broader population were surveyed on their hedonic and utilitarian motivations to shop for fashion apparel in high street and e-commerce environments. Statistical analysis was commenced through direct logistic regression and MANOVA.FindingsDemographics have limited association with shopping motivations, with gender and age only producing small effect sizes, while occupation, income and education has no significance. High street store preference is influenced by adventure and social shopping and e-commerce preference only by idea shopping. Spending over ¥1k per month on fashion apparel is influenced by gratification and idea shopping, and regular spending habits inspired by value shopping.Originality/valueThis empirical paper characterises the fingerprint of shopping motivations’ influence as singular to China while proving their limitation and need for a wider plethora of influential factors to be recognised.
The new wave of luxury: the meaning and value of luxury to the contemporary consumer
Authors: Kauppinen-Räisänen Hannele , Gummerus Johanna , von Koskull Catharina , Cristini Helene 
Published: June 2019

Purpose
The purpose of this study was to explore what luxury represents to contemporary consumers in their own life contexts.

Design/methodology/approach
A mixed-methods qualitative approach was adopted that comprised individual, personal interviews and focused interviews with small groups.

Findings
The study contributes to the field of luxury research by highlighting consumers’ interpretations of luxury as highly subjective, relative and contextual; showing that according to consumers, luxury relates to both consumption and non-consumption contexts; illustrating the value of luxury as a multidimensional construct in both contexts; and demonstrating how luxury may relate to a consumer’s desire to be meaningful and genuine, thereby generating prudential value. In these cases, luxury is closely linked to consumers’ perceptions of meaningfulness and well-being.

Practical implications
For marketing managers, the findings suggest that the wave of new luxury – seeking meaningfulness – may serve as a novel means of branding.

Originality/value
This study demonstrates that the significance of the concept of luxury transcends commercial settings and offerings, i.e. the brand, product or service. The findings show that luxury may also be generated in non-commercial contexts and specific activities (e.g. running, gardening). Based on these findings, it is proposed that luxury in non-commercial settings is characteristic of the new wave of luxury, and that in such settings, luxury may contribute to personal well-being, thereby generating prudential value.
Extending Janzen’s hypothesis to temperate regions: A test using subterranean ecosystems
Authors: Mammola Stefano , Piano Elena , Malard Florian , Vernon Philippe , Isaia Marco 
Published: June 2019

Abstract

Janzen’s hypothesis (1967; American Naturalist) predicts that tropical habitats with reduced thermal seasonality would select for species with narrow thermal tolerance, thereby limiting dispersal among sites of different elevations showing little overlap in temperature. These predictions have so far been tested by confronting tropical and temperate mountain communities, leaving unresolved the question of their generalization to habitats with low thermal seasonality outside the tropics.

We provide the first extension of Janzen’s hypothesis to temperate habitats, by testing for differences in thermal tolerance and elevational range among congeneric alpine spiders (Araneae: Linyphiidae: Troglohyphantes) occurring along a steep gradient of decreasing thermal seasonality with increasing cave depth. Using species from the same temperate region rather than from distinct biogeographic regions avoids confounding the effects of short‐ and long‐term climatic variability on thermal tolerance and elevational range extent.

Following Jansen’s assumptions, we predicted that cave habitats with low thermal seasonality would select for narrow thermal tolerance. Also, specialized subterranean species would exhibit both narrower elevational range extents and smaller realized thermal niche breadths. Initially, we showed that thermal seasonality and the overlap in temperature across caves were considerably lower in deep than in shallow cave habitats. Then, we measured thermal tolerance and used morphological traits to quantify the degree of specialization to subterranean life of 11 spider species.

We found that thermal tolerance decreased with increasing subterranean specialization. Deep subterranean species reached their critical temperature at 1–4°C above their habitat temperature, whereas shallow subterranean species withstood a twofold larger temperature increase. At last, we demonstrated that a species’ elevational range extent and the variation of temperature encountered across its range decreased with increasing specialization to deep subterranean life.

Our integrative work, being grounded in organismal and habitat measures, represents the first generalization of Janzen’s framework to caves and provides a conceptual framework to disentangle the effect of long‐term climate variability on subterranean biodiversity patterns. Extending Janzen’s thoughts to a broader range of ecosystems is key to understanding how the ecological specialization–dispersal trade‐off may constrain the response of species to climate change.

Behavioral and neural sensitivity to uncertain threat in individuals with alcohol use disorder: Associations with drinking behaviors and motives
Authors: Gorka Stephanie M. , Kreutzer Kayla A. , Petrey Kelsey M. , Radoman Milena , Phan Kinh Luan 
Published: June 2019

AbstractA developing theory is that individuals with alcohol use disorder (AUD) display exaggerated reactivity to threats that are uncertain (U‐threat), which facilitates excessive drinking as a means of avoidance‐based coping. There is a promising initial behavioral evidence supporting this theory; however, the neural bases of reactivity to U‐threat in individuals with AUD have not been examined. The extent to which biomarkers of U‐threat reactivity map onto drinking behaviors and coping motives for alcohol use is also unknown. The current study therefore examined group differences in behavioral and neural reactivity to U‐threat in adults with and without AUD. The study also tested whether behavior and brain responses to U‐threat correlate with problematic drinking and coping motivated drinking. Volunteers (n = 65) with and without a history of AUD (38 AUD, 27 controls) were included and completed a well‐validated threat‐of‐shock task to probe responses to U‐threat and predictable threat (P‐threat) while startle eyeblink potentiation was collected. Individuals also completed a newly designed, analogous version of the task during functional magnetic resonance imaging (fMRI). Results indicated that individuals with AUD displayed greater startle magnitude during U‐threat, but not P‐threat, and greater right insula and dorsal anterior cingulate cortex (dACC) activation during both forms of threat compared with controls. Startle magnitude and insula activation during U‐threat positively correlated with self‐reported problem drinking and coping motives for alcohol use. Findings demonstrate that individuals with AUD display exaggerated sensitivity to U‐threat at the behavioral and neural level and that these multimethod biomarkers tap into negative reinforcement processes of alcohol abuse.
The Demographic Consequences of the End of Chile's Nitrate Boom, c.1907–1940

Published: June 2019

AbstractThis article deals with the demographic consequences of the end of Chile's nitrate boom following the 1929 crisis. The traditional economic historiography has maintained that this crisis impacted heavily on nitrate production, and that in turn the crisis triggered a permanent exodus from the nitrate districts to other geographical zones. Contrary to this widely held belief, we have shown in this article that: there was no substantial fall in production; there was indeed a fall in nitrate population, but this was limited; this took place in some nitrate areas only; overall, the decline in nitrate population was a short term phenomenon only. The population making a living from nitrate production (or activities directly related to it) did not emigrate in as large numbers as previously thought, since production remained high up to the 1960s.
Review: Transition from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS): a meta‐synthesis of parental and professional perspectives
Authors: Hill Adam , Wilde Sarah , Tickle Anna 
Published: June 2019

BackgroundTransition between Child and Adolescent Mental Health Services (CAMHS) and Adult Mental Health Services (AMHS) can be stressful for the young person and family alike. Previous reviews have focused on specific aspects of transition or perspectives of young people, or have not used systematic approaches to data identification and analysis. The objective of this review was to develop the understanding of the transition between CAMHS and AMHS by systematically identifying and synthesising evidence regarding professionals’ and parents/carers’ perspectives.MethodA systematic search in July 2018 was conducted on Medline, PsycINFO and CINAHL. Google Scholar and references of selected articles were also searched. Papers were included if they presented empirical qualitative research in peer‐reviewed journals with a primary focus on experiences of parents/carers and/or mental health professionals in relation to adolescents making the CAMHS‐AMHS transition. Data were extracted from each full‐text paper. The quality of included studies was appraised using an expanded Critical Appraisal Skills Programme (2018) tool, and studies’ results were synthesised using meta‐ethnography.ResultsFourteen studies of variable quality were identified. Four main third‐order constructs were developed through synthesis: (a) Service cultures; (b) Service resources and gaps; (c) Working relationships between the services; and (d) Leaving secure relationships for new ones.ConclusionsProfessionals and parents experience adolescents’ transition from nurturing and comprehensive CAMHS to more individualistic AMHS as having many barriers. There is desire for better preparation for transition between services and relationships, more joint working and better CAMHS‐AMHS communication. AMHS service gaps exist, for example for those with neurodevelopmental conditions.
Exact Constraint Satisfaction for Truly Seamless Parametrization
Authors: Mandad M. , Campen M. 
Published: June 2019

AbstractIn the field of global surface parametrization a recent focus has been on so‐called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of surfaces of arbitrary topology, relate the parametrization across the cuts between charts via transition functions from special classes of transformations. This effectively makes the cuts invisible to applications which are invariant to these specific transformations in some sense. In actual implementations of these parametrization approaches, however, these restrictions are obeyed only approximately; errors stem from the tolerances of numerical solvers employed and, ultimately, from the limited accuracy of floating point arithmetic. In practice, robustness issues arise from these flaws in the seamlessness of a parametrization, no matter how small. We present a robust global algorithm that turns a given approximately seamless parametrization into an exactly seamless one ‐ that still is representable by standard floating point numbers. It supports common practically relevant additional constraints regarding boundary and feature curve alignment or isocurve connectivity, and ensures that these are likewise fulfilled exactly. This allows subsequent algorithms to operate robustly on the resulting truly seamless parametrization. We believe that the core of our method will furthermore be of benefit in a broader range of applications involving linearly constrained numerical optimization.
Accurate Synthesis of Multi‐Class Disk Distributions
Authors: Ecormier‐Nocca Pierre , Memari Pooran , Gain James , Cani Marie‐Paule 
Published: June 2019

AbstractWhile analysing and synthesising 2D distributions of points has been applied both to the generation of textures with discrete elements and for populating virtual worlds with 3D objects, the results are often inaccurate since the spatial extent of objects cannot be expressed. We introduce three improvements enabling the synthesis of more general distributions of elements. First, we extend continuous pair correlation function (PCF) algorithms to multi‐class distributions using a dependency graph, thereby capturing interrelationships between distinct categories of objects. Second, we introduce a new normalised metric for disks, which makes the method applicable to both point and possibly overlapping disk distributions. The metric is specifically designed to distinguish perceptually salient features, such as disjoint, tangent, overlapping, or nested disks. Finally, we pay particular attention to convergence of the mean PCF as well as the validity of individual PCFs, by taking into consideration the variance of the input. Our results demonstrate that this framework can capture and reproduce real‐life distributions of elements representing a variety of complex semi‐structured patterns, from the interaction between trees and the understorey in a forest to droplets of water. More generally, it applies to any category of 2D object whose shape is better represented by bounding circles than points.
Deep Video‐Based Performance Cloning

Published: June 2019

AbstractWe present a new video‐based performance cloning technique. After training a deep generative network using a reference video capturing the appearance and dynamics of a target actor, we are able to generate videos where this actor reenacts other performances. All of the training data and the driving performances are provided as ordinary video segments, without motion capture or depth information. Our generative model is realized as a deep neural network with two branches, both of which train the same space‐time conditional generator, using shared weights. One branch, responsible for learning to generate the appearance of the target actor in various poses, uses paired training data, self‐generated from the reference video. The second branch uses unpaired data to improve generation of temporally coherent video renditions of unseen pose sequences. Through data augmentation, our network is able to synthesize images of the target actor in poses never captured by the reference video. We demonstrate a variety of promising results, where our method is able to generate temporally coherent videos, for challenging scenarios where the reference and driving videos consist of very different dance performances.
Effects of Case and Transitivity on Processing Dependencies: Evidence From Niuean
Authors: Tollan Rebecca , Massam Diane , Heller Daphna 
Published: June 2019

AbstractWe investigate the processing of wh questions in Niuean, a VSO ergative–absolutive Polynesian language. We use visual‐world eye tracking to examine how preference for subject or object dependencies is affected (a) by case marking of the subject (ergative vs. absolutive) and object (absolutive vs. oblique), and (b) by the transitivity of the verb (whether the object is obligatory). We find that Niuean exhibits (a) an effect of case, whereby dependencies of arguments with absolutive case (whether subjects or objects) are preferred over dependencies of arguments with ergative or oblique case, and (b) an effect of transitivity, whereby dependencies of obligatory objects (i.e., of transitive verbs) are preferred over dependencies of optional objects (i.e., of intransitive verbs). These results constitute evidence against theories that appeal to a universal subject advantage, or to the linear distance between filler and gap. Instead, the effect of case is consistent with a frequency‐based account: Because absolutive case has a wider syntactic distribution than ergative or oblique, absolutive dependencies are easier to process. The effect of transitivity reflects sensitivity of the parser to whether or not an argument is obligatory. We propose that these two strategies could be unified if the parser prefers dependencies with arguments that are more likely to materialize.
Deconstructing the Financialization of Healthcare
Authors: Hunter Benjamin M. , Murray Susan F. 
Published: June 2019

ABSTRACTFinancialization is promoted by alliances of multilateral ‘development’ organizations, national governments and owners and institutions of private capital. In the healthcare sector, the leveraging of private sources of finance is widely argued as necessary to achieve the Sustainable Development Goal 3 target of universal health coverage. Employing social science perspectives on financialization, the authors of this article contend that this is a new phase of capital formation. The article traces the antecedents, institutions, instruments and ideas that facilitated the penetration of private capital in this sector, and the emergence of new asset classes that distinguish it. The authors argue that this deepening of financialization represents a fundamental shift in the organizing principles for healthcare systems, with negative implications for health and equality.
Digital Module 06: Bayesian Psychometrics—Posterior Predictive Model Checking https://ncme.elevate.commpartners.com
Authors: Ames Allison , Myers Aaron 
Published: June 2019

AbstractDrawing valid inferences from modern measurement models is contingent upon a good fit of the data to the model. Violations of model‐data fit have numerous consequences, limiting the usefulness and applicability of the model. As Bayesian estimation is becoming more common, understanding the Bayesian approaches for evaluating model‐data fit models is critical. In this instructional module, Allison Ames and Aaron Myers provide an overview of Posterior Predictive Model Checking (PPMC), the most common Bayesian model‐data fit approach. Specifically, they review the conceptual foundation of Bayesian inference as well as PPMC and walk through the computational steps of PPMC using real‐life data examples from simple linear regression and item response theory analysis. They provide guidance for how to interpret PPMC results and discuss how to implement PPMC for other model(s) and data. The digital module contains sample data, SAS code, diagnostic quiz questions, data‐based activities, curated resources, and a glossary.
Can we teach old drugs new tricks?—Repurposing of neuropharmacological drugs for inflammatory skin diseases
Authors: Abels Christoph , Soeberdt Michael 
Published: June 2019

AbstractDespite the “hype” for monoclonal antibodies, the so‐called biologics, which added significant value to the therapeutic armamentarium of dermatologists and improved the life of many patients, but may exhibit significant adverse effects, the vast majority of dermatological patients suffering from atopic dermatitis or psoriasis is still treated topically. Thus, there is a huge need for locally applied, locally acting drugs for inflammatory skin diseases with better risk‐benefit profiles compared to topical corticosteroids or calcineurin inhibitors. Drug repositioning is a complex process, but offers advantages, in particular for indications with lower revenues. In this viewpoint, the neuroendocrine system of the skin is described as an attractive drug target because it contributes significantly to neutralizing external noxious agents prior to inducing immune or vascular changes leading to the clinical signs of skin inflammation, for example, itch and erythema. In addition, epidermis and dermis are accessible for topically applied products which may act locally without pharmacodynamically relevant systemic exposure limiting adverse events. Moreover, since numerous drugs have been evaluated for various CNS diseases, some failed and some approved, this resource should be exploited for repurposing as anti‐inflammatory drugs for topical application, for example, cannabidiol, fingolimod or asimadoline. Finally, a screening algorithm is shared which gives direct evidence of links between drug and inflammatory skin diseases.
