Housing wealth effects for private and subsidized homeowners
Authors: Wong Siu Kei , Deng Kuang Kuang , Cheung Ka Shing 
Published: July 2018

Purpose
This paper aims to examine the effect of housing wealth on household consumption when there are resale and refinancing constraints that prevent housing assets from being cashed out.

Design/methodology/approach
Based on Household Expenditure Survey data in Hong Kong from 1999 to 2010, regression analysis is applied to compare the housing wealth effects of private and subsidized homeowners. Propensity score matching is adopted to ensure that the two groups of homeowners share similar household income. Further regression analysis is conducted to examine private homeowners’ consumption when their recourse mortgages are in negative equity.

Findings
Subsidized homeowners, who are not allowed to resell their units before sharing their capital gain with the government, experienced an insignificant housing wealth effect. While private homeowners experienced a significant housing wealth effect, the effect was weakened in the presence of a resale constraint induced by negative equity. The results remain robust after the application of more rigorous sample selection through propensity score matching.

Research limitations/implications
The analyses are subject to two potential data limitations. One is a relatively small sample size. The other is that data on financial assets and mortgages are unavailable and have to be indirectly controlled through household characteristics. Nevertheless, our estimated marginal propensity to consume out of housing wealth is 0.03 of the annual household consumption for private homeowners, which is within the range of estimates reported in previous literature.

Practical implications
This study shows that the housing wealth effect enjoyed in the private sector does not necessarily apply to the subsidized sector where resale and refinancing constraints exist. This is not to suggest that the constraints be removed. Rather, policymakers should be aware of the tradeoff: while the constraints ensure that government subsidies are used to assist home ownership, not capital gain, they also bring about consumption inequality in a society, especially in a booming housing market.

Originality/value
Our findings extend the literature on the housing wealth effect, which has been exclusively focusing on private homeowners, to subsidized homeowners. This study also adds to the literature on housing welfare by highlighting that the resale constraints of subsidized housing can weaken the housing wealth effect.
Cross-trained worker assignment and comparative analysis on throughput of divisional and rotating seru
Authors: Wu Lang , Chan Felix T.S. , Niu Ben , Li Li 
Published: July 2018

Purpose
Seru (cell) manufacturing system has achieved huge success in production. However, related research is limited, especially, the problem of cross-trained worker assignment. The purpose of this paper is to solve this problem for two representative seru types, divisional and rotating seru, and subsequently, compare throughput performance between the two seru types under reasonable worker-task assignment.

Design/methodology/approach
For the cross-trained worker assignment problem, this research presents new models aiming at maximum throughput of seru and workload balance of workers under considering skill levels (SLs) and several practical constraints. Furthermore, factorial experiments that involve four factors, the number of tasks (NT), gap of task time, SL and gap of SL, are performed to compare throughput performance between divisional and rotating seru.

Findings
First, the maximum throughput of the divisional seru is better than that of the rotating seru under suitable worker assignment. Second, in the seru which has less difference of task time, throughput performance of the rotating seru is better than the divisional seru when the NT is close to the number of assigned workers. Moreover, the influence tendency of the four factors on throughput gap between the two seru types is significant.

Originality/value
This research addresses the worker-task assignment for divisional and rotating seru based on their characteristics. Several findings can help decision maker select more applicable seru type according to various production environments from the perspective of optimum throughput.
Entrepreneurial ecosystems: a systematic review
Authors: Maroufkhani Parisa , Wagner Ralf , Wan Ismail Wan Khairuzzaman 
Published: July 2018

Purpose
The literature on entrepreneurial ecosystems is fragmented, and yet, no studies have paid attention to integrating the available studies. The purpose of this study is to provide a systematic review of contributions related to entrepreneurial ecosystems.

Design/methodology/approach
This literature review evaluates studies that are covered in the Web of Science index.

Findings
In addition to the recent state of research (covering industries, geographical scopes, methodologies, etc.), this study provides an extension of Isenberg’s (2011) model of entrepreneurial ecosystems.

Research limitations/implications
A new avenue arises for both conceptual and empirical research by emphasizing crowdsourcing as a contributing element for the entrepreneurial ecosystem. Future studies can evaluate the effectiveness of different types of crowdsourcing profoundly to make sure whether creating a promising ecosystem all types of crowdsourcing have a similar value or impact.

Practical implications
For public policy and local decision-makers, both collaboration opportunities and interaction interfaces between the stakeholders of the entrepreneurial need to be reconsidered in the design of entrepreneurial ecosystems.

Social implications
Higher degrees of collaboration, information exchange and innovation are likely to yield favorable entrepreneurship environments.

Originality/value
Novelty of this study arises from integrating crowdsourcing theory in the systematic review of entrepreneurial ecosystems.
Service user perspectives of an early intervention in psychosis service: a service evaluation
Authors: Watkins Simon , Sanderson Chris , Richards Victoria 
Published: July 2018

Purpose
The purpose of this paper is to gather the perspectives of individuals accessing an early intervention in psychosis service (EIPS), in order to inform service development.

Design/methodology/approach
Individual interviews (n=9) and one focus group (n=7) were conducted. Discussions focused on open questions pertaining to service users’ (SU’s) experiences of accessing the EIPS. The results were analysed using inductive thematic analysis.

Findings
Inductive thematic analysis was used and three main themes were generated: consistency and communication, facilitating therapeutic relationships between EIPS staff and SU’s; pushing boundaries, relating to the importance of services taking a graded approach to developing therapeutic relationships and (re)engaging in activities; and normalising and validating experiences of psychosis. Participants emphasised the importance of relationships with EIPS staff and fellow SUs and highlighted how SUs can feel fearful and vulnerable when staff are not accessible or they view their care as inconsistent. Participants further emphasised the need for practitioners to balance an approach that de-stigmatises psychotic experiences whilst validating distress.

Practical implications
Consistency of support from EIPSs can be as important as flexibility. Clinicians should carefully consider the balance between validating and normalising distressing experiences associated with psychosis. Offering social activities with other SUs can facilitate therapeutic relationships and recovery but the results suggest that this should be facilitated in a graded way.

Originality/value
The paper addresses current need in the literature to understand the experiences of people using services in order to improve the quality of the services provided.
Empowering subsistence women entrepreneurs in India
Authors: Saripalli Bhavani Shankar , Chawan Vinaysingh , Gunta Srinivas 
Published: July 2018

Purpose
Empowerment of women by social enterprises in emerging economies has received attention from researchers. This paper aims to study three social enterprises in India that aim to empower subsistence women entrepreneurs.

Design/methodology/approach
A comparative case analysis of three social enterprises is done to develop understanding of systems and processes adopted by them. Sources such as published journal and news articles, case studies, success stories and official websites are used for data collection.

Findings
The study found that all three organisations strive to increase the asset base of members by organizing disempowered subsistence producers lacking market power; extending services throughout the value chain, i.e. from raw material supply to marketing of products; ploughing back regular incomes and bonuses through mechanisms acceptable to all members; and empowering subsistence producers to gain market power and ability to choose. The interventions give market exposure and voice to the concerns of women producers. These organisations successfully leverage the strength of their relations with civil society and markets in sustaining the business. Women empowerment was found to be achieved through regular income, collective voice, ability to take decisions and creation of social value.

Research limitations/implications
This paper does not take into consideration enterprises promoted by government.

Practical implications
A conceptual framework is suggested in this paper along with insights for organisations interested in collectivising subsistence women for empowering them.

Originality/value
The conceptual framework provided in this paper enriches the understanding of social enterprises working with the objective of women empowerment.
Association of characteristics of people with type 2 diabetes mellitus with discordant values of fasting glucose and HbA1c

Published: July 2018

AbstractBackgroundPrimary care physicians frequently encounter people with type 2 diabetes mellitus (T2DM) with discordant values for fasting glucose and HbA1c. The aim of this study was to identify the prevalence and characteristics of people in whom blood glucose and HbA1c did not match.MethodsOverall, 64 553 people with T2DM from 939 general or internal medicine practices (Disease Analyzer database, Germany; January 2013–December 2015) were analyzed. Multivariable logistic regression models were used to identify associations between baseline clinical characteristics, comorbidity, and glucose‐lowering treatment and discordance of fasting glucose and HbA1c values measured at the same visit.ResultsOverall, 8582 (13%) patients had fasting glucose ≥140 mg/dL and HbA1c <7% (<53 mmol/mol), and 6508 (10%) had HbA1c ≥7% (≥53 mmol/mol) and fasting glucose <140 mg/dL. Using patients with both fasting glucose <140 mg/dL and HbA1c <7% as the reference (n = 31 834; 49%), solitary high fasting glucose values (and HbA1c <7%) were positively associated with higher age, male sex, longer diabetes duration, obesity, liver disease, low estimated glomerular filtration rate (eGFR), and glucose‐lowering treatment. High HbA1c (and fasting glucose <140 mg/dL) was positively related to longer diabetes duration, obesity, neuropathy, retinopathy, low eGFR, and insulin treatment. There were lower odds of having solitary increased HbA1c ≥7% (fasting glucose <140 mg/dL) with higher age, hypertension, depression, and the number of diabetes patients (>200) per practice.ConclusionsA considerable number of people with T2DM in primary care practices have discordant fasting blood glucose and HbA1c values. People who have discordant glycemic values have different characteristics.
ConcaveCubes: Supporting Cluster‐based Geographical Visualization in Large Data Scale

Published: July 2018

AbstractIn this paper we study the problem of supporting effective and scalable visualization for the rapidly increasing volumes of urban data. From an extensive literature study, we find that the existing solutions suffer from at least one of the drawbacks below: (i) loss of interesting structures/outliers due to sampling; (ii) supporting heatmaps only, which provides limited information; and (iii) no notion of real‐world geography semantics (e.g., country, state, city) is captured in the visualization result as well as the underlying index. Therefore, we propose ConcaveCubes, a cluster‐based data cube to support interactive visualization of large‐scale multidimensional urban data. Specifically, we devise an appropriate visualization abstraction and visualization design based on clusters. We propose a novel concave hull construction method to support boundary based cluster map visualization, where real‐world geographical semantics are preserved without any information loss. Instead of calculating the clusters on demand, ConcaveCubes (re)utilizes existing calculation and visualization results to efficiently support different kinds of user interactions. We conduct extensive experiments using real‐world datasets and show the efficiency and effectiveness of ConcaveCubes by comparing with the state‐of‐the‐art cube‐based solutions.
Landscaper: A Modeling System for 3D Printing Scale Models of Landscapes
Authors: Allahverdi K. , Djavaherpour H. , Mahdavi‐Amiri A. , Samavati F. 
Published: July 2018

AbstractLandscape models of geospatial regions provide an intuitive mechanism for exploring complex geospatial information. However, the methods currently used to create these scale models require a large amount of resources, which restricts the availability of these models to a limited number of popular public places, such as museums and airports. In this paper, we have proposed a system for creating these physical models using an affordable 3D printer in order to make the creation of these models more widely accessible. Our system retrieves GIS relevant to creating a physical model of a geospatial region and then addresses the two major limitations of affordable 3D printers, namely the limited number of materials and available printing volume. This is accomplished by separating features into distinct extruded layers and splitting large models into smaller pieces, allowing us to employ different methods for the visualization of different geospatial features, like vegetation and residential areas, in a 3D printing context. We confirm the functionality of our system by printing two large physical models of relatively complex landscape regions.
CFGExplorer: Designing a Visual Control Flow Analytics System around Basic Program Analysis Operations
Authors: Devkota Sabin , Isaacs Katherine E. 
Published: July 2018

AbstractTo develop new compilation and optimization techniques, computer scientists frequently Consult program analysis artifacts such as Control flow graphs (CFGs) and traces of executed instructions. A CFG is a directed graph representing possible execution paths in a program. CFGs are commonly visualized as node‐link diagrams while traces are commonly viewed in raw text format. Visualizing and exploring CFGs and traces is challenging because of the complexity and specificity of the operations researchers perform. We present a design study where we collaborate with computer scientists researching dynamic binary analysis and compilation techniques. The research group primarily employs CFGs and traces to reason about and develop new algorithms for program optimization and parallelization. Through questionnaires, interviews, and a year‐long observation, we analyzed their use of visualization, noting that the tasks they perform match common subroutines they employ in their techniques. Based on this task analysis, we designed CFGExplorer, a visual analytics system that supports computer scientists with interactions that are integrated with the program structure. We developed a domain‐specific graph modification to generate graph layouts that reflect program structure. CFGExplorer incorporates structures such as functions and loops, and uses the correspondence between CFGs and traces to support navigation. We further augment the system to highlight the output of program analysis techniques, facilitating exploration at a higher level. We evaluate the tool through guided sessions and semi‐structured interviews as well as deployment. Our collaborators have integrated CFGExplorer into their workflow and use it to reason about programs, develop and debug new algorithms, and share their findings.
Illustrative Multivariate Visualization for Geological Modelling
Authors: Rocha A. , Mota R. C. R. , Hamdi H. , Alim U. R. , Costa Sousa M. 
Published: July 2018

AbstractIn this paper, we present a novel illustrative multivariate visualization for geological modelling to assist geologists and reservoir engineers in visualizing multivariate datasets in superimposed representations, in contrast to the single‐attribute visualizations supported by commercial software. Our approach extends the use of decals from a single surface to 3D irregular grids, using the layering concept to represent multiple attributes. We also build upon prior work to augment the design and implementation of different geological attributes (namely, rock type, porosity, and permeability). More specifically, we propose a new sampling strategy to generate decals for porosity on the geological grid, a hybrid visualization for permeability which combines 2D decals and 3D ellipsoid glyphs, and a perceptually‐based design that allows us to visualize additional attributes (e.g., oil saturation) while avoiding visual interference between layers. Furthermore, our visual design draws from traditional geological illustrations, facilitating the understanding and communication between interdisciplinary teams. An evaluation by domain experts highlights the potential of our approach for geological modelling and interpretation in this complex domain.
A Survey of Flattening‐Based Medical Visualization Techniques
Authors: Kreiser J. , Meuschke M. , Mistelbauer G. , Preim B. , Ropinski T. 
Published: July 2018

AbstractIn many areas of medicine, visualization research can help with task simplification, abstraction or complexity reduction. A common visualization approach is to facilitate parameterization techniques which flatten a usually 3D object into a 2D plane. Within this state of the art report (STAR), we review such techniques used in medical visualization and investigate how they can be classified with respect to the handled data and the underlying tasks. Many of these techniques are inspired by mesh parameterization algorithms which help to project a triangulation in ℝ3 to a simpler domain in ℝ2. It is often claimed that this makes complex structures easier to understand and compare by humans and machines. Within this STAR we review such flattening techniques which have been developed for the analysis of the following medical entities: the circulation system, the colon, the brain, tumors, and bones. For each of these five application scenarios, we have analyzed the tasks and requirements, and classified the reviewed techniques with respect to a developed coding system. Furthermore, we present guidelines for the future development of flattening techniques in these areas.
Aktualisierung der S1‐Leitlinie zur Definition und Therapie der primären Hyperhidrose
Authors: Rzany Berthold , Bechara Falk G. , Feise Konstantin , Heckmann Marc , Rapprich Stefan , Wörle Birgit 
Published: July 2018

ZusammenfassungDie fokale Hyperhidrose kann zu erheblichen sozialen und beruflichen Einschränkungen und damit zu einer ausgeprägten Verminderung der Lebensqualität führen. Der primären Hyperhidrose liegen keine internistischen Erkrankungen oder externen Ursachen zugrunde. Sie tritt vor allem im Bereich von Arealen mit einer großen Schweißdrüsendichte wie den Achseln und den Händen auf. Die Diagnose der Hyperhidrose basiert auf der Anamnese und der Klinik. Unterstützt wird die Diagnostik durch Gravimetrie (die Schweißmengenmessung) und den Iod‐Stärke‐Test (der das vom Schwitzen betroffene Areal definiert). Zur Behandlung der primären Hyperhidrose stehen eine Reihe von Verfahren wie die topische Therapie, die Injektionstherapie mit Botulinumtoxin A, die Leitungswasser‐Iontophorese, die Therapie mit Radiofrequenz, Mikrowellen oder Ultraschall bis hin zu den operativen Interventionen wie der axillären Saugkürettage oder der Sympathektomie zur Verfügung. Auch systemische Therapeutika (vor allem Anticholinergika) kommen zur Anwendung. Die Auswahl der geeigneten Behandlungsmaßnahmen sollte individuell auf die Lokalisation, die vorangegangen Behandlungen und die Wünsche des Patienten abgestimmt werden.

Published: July 2018

ZusammenfassungFür eine erfolgreiche Behandlung von Patienten mit Ulcus cruris ist es essentiell, die zugrundeliegende Ätiologie zu klären und, wenn möglich, eine kausale Therapie einzuleiten. Begleitend ist die an den Phasen der Wundheilung orientierte Wundbehandlung, meist in Verbindung mit einer Kompressionstherapie, die Therapie der Wahl. Der Stellenwert der systemischen Therapien wird in Abhängigkeit der zugrundeliegenden Genese sehr unterschiedlich und oft kontrovers beurteilt. In diesem Übersichtsartikel werden die aktuellen Aspekte der systemischen medikamentösen Therapien für Patienten mit Ulcus cruris bei den häufigen Genesen chronische venöse Insuffizienz, periphere arterielle Verschlusskrankheit, Livedovaskulopathie, Vaskulitis, Necrobiosis lipoidica, Calciphylaxie und Pyoderma gangraenosum differenziert vorgestellt und kritisch diskutiert.Zusammenfassend kann festgestellt werden, dass es sich bei vielen der hier vorgestellten Therapien um einen Off‐Label‐Use handelt. Bei den häufiger vorkommenden Wundarten wie beispielsweise Ulcus cruris venosum, mixtum und arteriosum sind Medikamente für die Therapie zwar hoffnungsvolle Optionen, bisher aber in der Regel kein Behandlungsstandard. Im Gegensatz hierzu haben systemische Therapien bei den anderen hier vorgestellten Krankheitsbildern eine meist zentral wichtige Bedeutung. Es sind in erster Linie immunmodulierende und rheologisch wirksame Medikamente, die eingesetzt werden, um die Wundheilung zu beschleunigen.
