Proprioceptive Deficits in Inactive Older Adults are not Reflected in Discrete Reaching Performance
Authors: Kitchen Nick M. , Miall R Chris 
Published: August 2018

AbstractDuring normal healthy ageing there is a decline in the ability to control simple movements, characterised by increased reaction times, movement durations and variability. There is also growing evidence of age-related proprioceptive loss which may contribute to these impairments. However this relationship has not been studied in detail for the upper limb. We recruited 20 younger adults (YAs) and 31 older adults (OAs) who each performed 2 tasks on a 2D robotic manipulandum. The first assessed dynamic proprioceptive acuity using active, multi-joint movements towards visually presented targets, with movement constrained by the robot to a predefined path. Participants made perceptual judgements of the lateral position of the unseen arm. The second was a rapid motor task which required fast, accurate movements to the same targets in the absence of hand position visual feedback, and without constraint by the robot. We predicted that the variable proprioceptive error (uncertainty range) from Task 1 would be increased in physically inactive OAs and would predict increased movement variability in Task 2. Instead we found that physically inactive OAs had larger systematic proprioceptive errors (bias). Neither proprioceptive acuity nor bias was related to motor performance in either age group. We suggest that previously reported estimates of proprioceptive decline with ageing may be exaggerated by task demands and that the extent of these deficits is unrelated to discrete, ballistic movement control. The relationship of dynamic proprioceptive acuity with movement control in tasks which emphasise online proprioceptive feedback for performance is still unclear and warrants further investigation.
Multiple substance use among patients attending treatment for substance-related problems in Switzerland
Authors: Maffli Etienne , Astudillo Mariana 
Published: August 2018

Purpose
The purpose of this paper is to estimate the share of multiple substance disorders among clients entering treatment for substance-related problems, to identify the most frequent combinations of the substances involved and to investigate the profiles of the clients involved.

Design/methodology/approach
Data were taken from the Swiss treatment monitoring system act-info applied among inpatient and outpatient facilities (reporting years 2013–2015). All cases with information on multiple substance disorders, according to a definition close to the diagnosis F19 from the ICD-10 classification of disease were included. The measurements comprised designated primary substance, existing multiple substance use disorder, substances involved and basic socio-demographics.

Findings
From 10,009 clients included in the study, 1,653 (16.5 per cent) were reported as having multiple substance use disorders. A great variety of substance combinations was identified and alcohol was found in the majority of them.

Practical implications
Treatment strategies targeting accurately substance-related disorders as a whole complex should be promoted. In particular the alcohol-related aspect of the disorder should not be neglected when the focus is on illegal drugs.

Originality/value
Multiple substance use was until recently not sufficiently documented in treatment monitoring systems. A recent version of the European treatment demand indicator (TDI) has introduced the notion of “polydrug use problem” as complementary information to the primary substance, which remains the key variable for reporting treatment demand. This study represents a first attempt to explore systematically this new data.
The impact of the core company’s strategy on the dimensions of supply chain integration
Authors: Feyissa Tesfaye Tolu , Sharma R. Raghavendra Kumar , Lai Kuei-Kuei 
Published: August 2018

PurposeNowadays, supply chain integration (SCI) is considered as an enabler of competitive firm performance. It has three important dimensions: internal, supplier and customer integration. Understanding the interaction between these dimensions and organisational strategy would pave the way for effective implementation of SCI. The famous Mileset al. (1978) strategy typology classifies firms into four strategy types: defenders, prospectors, analysers and reactors. The purpose of this paper is to explore the impact of the core company’s product-market innovation strategy on the dimensions of SCI, and to investigate the comparative strength of each dimension of SCI in defenders and prospectors.Design/methodology/approachPrimary data were collected through an online survey of 112 firms in 24 countries across Africa, Asia, Europe and North America. Direct and mediated relationships were assessed by conducting structural equation modelling on the dimensions of SCI and product-market innovation strategy variables. Cluster analysis was conducted on organisational strategy variables to group the firms into different strategy types. Next, a one-way analysis of variance was applied to assess the impact of organisational strategy on each dimension of the SCI. Finally, apost hocanalysis was conducted to compare the strength of each dimension of the SCI against the different strategy types.FindingsThe results indicate that internal integration (II) mediates the positive effects of the core company’s product-market innovation strategy on supplier and customer integration. Furthermore, the results indicate that prospectors have stronger internal, supplier and customer integration as compared to defenders.Research limitations/implicationsThis study had two main limitations. One limitation is the lack of consideration of possible differences in the strengths of the investigated relationships across different geographical locations and cultures. The second limitation is the inability of the cross-sectional research design to capture the dynamics in the process of adopting SCI and organisational strategy.Practical implicationsThe present study highlights to executives the need for understanding the implications of specific strategies on the SC linkages and relationships that are required to implement those strategies. Thus, it could serve as a preliminary clue in decision-making for establishing integrated SC that is compatible with the organisational strategy. Furthermore, it could serve as a guidance to managers in steering their firms in the organisational adaptive cycle, by indicating that the implementation of product-market innovation strategy requires adopting strong SCI, and by highlighting the importance of adopting II prior to external integration.Originality/valueThis paper tests relationships that explain how the core company’s strategy influences each dimension of SCI.
Opera costumes and the value of object biographies
Authors: Waller Helen J. , Waller David S. 
Published: August 2018

Purpose
The purpose of this paper is to observe the nature of documentation and the description used in object biographies by an auction house catalogue and an online museum collection database in relation opera costumes. This research aims to discuss the issues of cultural and economic value in relation to objects in the art world, and examine examples of object biographies for opera costumes that are sold at an auction and exhibited in a museum.

Design/methodology/approach
The object biographies are compared from an auction house catalogue and the online museum collection database, based on two factors: costumes worn by a famous singer and costumes designed by a famous designer.

Findings
This study identified the valuation methods of auction houses and museums, including accounting for the market value and fair value, as well as social and cultural values. The nature of the documentation also clearly shows the different purpose of the object biographies. For auction houses the biography needs to be short and specific as it provides sufficient information and is read out at the auction, while art catalogues can also be used by experts as part of the conversation to understanding heritage value, and will also be viewed and used by researchers, investors, other auction house specialists and art world professionals.

Research limitations/implications
By comparing two institutions, auction houses and museums, this study has shown that the information that is documented and how it is presented in object biographies is determined by the goals of the institutions. These goals may vary or overlap in providing information, demonstrating cultural importance, to be spoken allowed to an audience and make sales, or to educate, conserve and preserve.

Practical implications
This study shows that to some extent museum online databases display their collection removed from cultural context, with an isolated image of the item, and in an organised, digitally accessible manner. A potential implication is that museums should not only digitally catalogue an item, but also provide discussion and the cultural background and significance of the item.

Social implications
Auction catalogues are written for a specific event (the auction), while the online museum collection database is meant to be a permanent record, which aims to digitally preserve objects and provide access to images and information to a general audience, and further could be edited with amendments or new information when future research or events lead to potential updates.

Originality/value
This study adds to the discourse on approaches to the understanding of costumes as an art object of significance and their potential cultural, economic and heritage value, particularly as represented in the documentation of object biographies.
Abstraction framework to support students in learning creative conceptual design
Authors: Fiorineschi Lorenzo 
Published: August 2018

Purpose
Learning systematic conceptual design approaches could be difficult for students who are asked to adapt their intuitive design rationale to more abstract and divergent thinking styles. The purpose of this study is to propose a conceptual design approach with a well-defined reference framework and procedure to help students to gradually move toward concreteness and to explore the design space.

Design/methodology/approach
The so-called problem–solution network approach has been taken as a reference and upgraded with a specific framework to manage abstraction levels. A first didactical application of the proposal is described, and specific feedbacks from students have been collected by means of an anonymous survey.

Findings
Despite the limited course time allotted for the argument, students’ feedbacks revealed that the proposed abstraction framework is useful to learn systematic conceptual design and to support the understanding of creative design thinking.

Research limitations/implications
The proposal has been applied on a single class of MS engineering students in a course where only a part of the available time was allotted to conceptual design activities. However, the received positive feedbacks are encouraging and allow pushing toward more comprehensive applications and investigations.

Originality/value
The proposal shown in this paper uses acknowledged concepts of abstraction and function to propose a new integrated framework to manage abstraction levels in problem solving activities. The framework has been implemented in a very recent conceptual design approach based on problem–solution co-evolution, which has been proposed to overcome the flaws ascribed to classical function-based methods.
Exploring innovation creation across rural and urban firms
Authors: Aryal Giri , Mann John , Loveridge Scott , Joshi Satish 
Published: August 2018

PurposeThe innovation creation literature primarily focuses on urban firms/regions or relies heavily on these data; less studied are rural firms and areas in this regard. The purpose of this paper is to employ a new firm-level data set, national in scale, and analyze characteristics that potentially influence innovation creation across rural and urban firms.Design/methodology/approachThe authors use the 2014 National Survey of Business Competitiveness (NSBC) covering multiple firm-level variables related to innovation creation combined with secondary data reflecting the regional business and innovative environments where these firms operate. The number of patent applications filed by these firms measures their innovation creation, and the paper employs a negative binomial regression estimation for analysis.FindingsAfter controlling for industry, county and state factors, rural and urban firms differ in their innovation creation characteristics and behaviors, suggesting that urban firms capitalize on their resources better than rural firms. Other major findings of the paper provide evidence that: first, for rural firms, the influence of university R&D is relevant to innovation creation, but their perception of university-provided information is not significant; and second, rural firms that are willing to try, but fail, in terms of innovation creation have a slight advantage over other rural firms less willing to take on the risk.Originality/valueThis paper is one of the first to analyze the 2014 NSBC, a firm-level national survey covering a wide range of innovation-related variables. The authors combine it with other regional secondary data, and use appropriate analytical modeling to provide empirical evidence of influencing factors on innovation creation across rural and urban firms.
Participants’ perception of training programmes in the tourism industry
Authors: Abbasian Saeid 
Published: August 2018

PurposeThe purpose of this paper is to deal mainly with the participants’ perception of their attendance in publicly funded training programmes in the tourism industry.Design/methodology/approachThe investigation is based on e-mail interviews with 12 employees in the Swedish tourism industry who have actively participated in such courses as well as some courses offered by private organisations.FindingsThe results show that the interviewees have a positive perception of their participation and they believe that their attendance has had an overall positive impact on them or on their businesses. Nevertheless, it is unclear whether their participation has had an extraordinarily positive impact on business outcomes in terms of subsequent increased turnover, greater productivity or sales, or an expanded customer base. Lack of time and money and the prevalence of unsuitable courses prevent business owners and their employees from attending such courses.Originality/valueThis research is the first Swedish qualitative investigation on the issue.

Authors: Parveen Sahdia , Haunch Kirsty , Kerry Fionnuala , Oyebode Janet 
Published: August 2018

Purpose
The purpose of this paper is to describe a study which explored the knowledge and attitudes of university students towards people living with dementia, and developed and tested a dementia awareness workshop, dementia detectives: university edition, designed to improve knowledge and foster positive attitudes to dementia in students.

Design/methodology/approach
Dementia detectives: university edition was launched during dementia awareness week and five workshops were delivered to university students. In total, 42 participants attended and completed a knowledge and attitude measure before and after the workshop, as well as rating the workshop with regards to satisfaction, relevance, understanding and whether they would recommend the workshop to friends.

Findings
Students perceived living with dementia to be a negative and stigmatised experience. The workshop scored highly in terms of satisfaction, relevance and understanding and all students stated that they would recommend the workshop to others. Paired t-tests found significant improvements in self-assessed dementia knowledge.

Research limitations/implications
This was a pilot evaluation and further testing with larger samples is required.

Practical implications
The workshop meets the requirements for tier 1 dementia education and training as outlined in the Dementia Core Skills and Knowledge Framework published by the Department of Health.

Social implications
The workshop has the potential to increase knowledge, change attitudes, improve empathy and contribute to the development of a dementia aware workforce through undergraduate education.

Originality/value
Dementia detectives: university edition is a novel interactive method of dementia education and training.
Disruptive potential of real estate crowdfunding in the real estate project finance industry
Authors: Montgomery Nicolle , Squires Graham , Syed Iqbal 
Published: August 2018

PurposeThe purpose of this paper is to review the literature on the Disruptive Innovation Theory and on the disruptive potential of real estate crowdfunding (RECF) in the real estate finance industry, assessing whether RECF constitutes a potentially disruptive innovation to the real estate finance industry. Based on a review and synthesis of the literature, the paper advances an initial conceptual framework of core characteristics of disruptive innovations. This framework is used to examine the disruptive potential of RECF in the real estate finance industry.Design/methodology/approachThis paper is a systematic literature review that synthesizes and analyzes relevant extant research articles retrieved from online databases.FindingsFindings suggest that according to the theory of disruptive innovations, and the core characteristics of disruptive innovations, RECF is a potentially disruptive innovation to the real estate finance industry. RECF seems to generally align with the classic characteristics of disruptive innovations. A more comprehensive and systematic analysis, supported by empirical data, is necessary to evaluate whether and to what extent RECF constitutes a disruptive innovation to the real estate finance industry.Research limitations/implicationsThis study has only captured and reviewed articles published and available in database searches. RECF is a nascent field that has recently begun receiving academic attention.Practical implicationsReal estate plays an integral part in the economy, and the way it is financed has become an increasingly important issue following the Global Financial Crisis. This paper provides useful insights for assessing whether and to what extent RECF may be disruptive to the real estate finance industry.Social implicationsRECF may potentially improve accessibility and affordability of real estate finance, thereby helping to address the problem of shortage of real estate project finance.Originality/valueWhile RECF is portrayed in the academic and gray literature as a disruptive innovation, its disruptive potential is yet to be determined. This paper advances an initial conceptual framework of defining characteristics of disruptive innovations. This framework is used to evaluate RECF as a potentially disruptive innovation in the real estate project finance industry. This study forms a basis for future empirical examination of the disruptive potential of RECF in the real estate finance industry.

Abstract

Architectural traits that determine the light captured in a given environment are an important aspect of the life‐history strategies of tropical tree species. In this study, we examined how interspecific variation in architectural traits is related to the functional traits of 45 coexisting tree species in Central Africa.

At the tree level, we measured tree diameter, total height and crown dimensions for an average of 30 trees per species (range: 14–72, total 968 trees) distributed over a large range of diameters (up to 162 cm). Using log–log models, we fitted species‐specific allometric relationships between tree diameter, height and crown dimensions. At the species level, we derived architectural traits (height and crown dimensions) at 15 cm and maximum diameters from species‐specific allometries. The architectural traits were then related to functional traits, including light requirements, wood density, leaf habit and dispersal mode.

Among the 45 coexisting tree species, we identified strong variations in height and crown allometries, along with architectural traits derived from these species‐specific allometries. There was a positive correlation among architectural traits, suggesting that large‐statured canopy species were taller and had larger and deeper crowns than small‐statured understorey species at all ontogenic stages. The relationships between architectural and functional traits highlighted a continuum of species between the large‐statured canopy species and the small‐statured understorey species. In this moist and seasonal forest, large‐statured canopy species tended to be light‐demanding, wind‐dispersed, deciduous and large contributors to forest biomass (high basal area), while small‐statured understorey species tended to be shade‐tolerant, animal‐dispersed, evergreen and most abundant in terms of stem density.

Our results highlighted strong architectural differences among coexisting tropical tree species in Central Africa. The relationships between architectural and functional traits provided insights into the life‐history strategy of tropical tree species.

Abstract

Glomeromycotinan fungi associate with plant roots in a ubiquitous mutualism, the arbuscular mycorrhiza. Vegetation type, spatial distance, and environmental variability represent the three main factors shaping the structure of Glomeromycotinan communities.

We present here one of the most comprehensive reports on Glomeromycotinan community structure in forest ecosystems, covering five ecosystem types. We explored the extent to which the latitudinal gradient in Glomeromycotinan diversity is confounded by the respective latitudinal gradient of host plants and how Glomeromycotinan communities diverge with spatial distance and environmental variability.

We show that latitudinal differences in Glomeromycotinan α‐ and β‐diversity are largely shaped by the zonation patterns of ecosystem types and that differences among Glomeromycotinan communities occurring in different ecosystems are considerably larger than those occurring within the same ecosystem type. In contrast, we could observe little to no differences in phylogenetic community structure across samples, irrespective of their origin. In conclusion, several community assembly rules for Glomeromycotina in the woody systems, such as phylogenetic relationships, differed from those in grassland systems.

Synthesis. We provide strong evidence that the latitudinal gradient in Glomeromycotinan diversity in woody systems is mainly driven by latitudinal differences in forest habitat types. Further exploring the causes of these differences across habitat types would probably reveal underexplored facets of the ecology of arbuscular mycorrhizal fungi.
