Authors: Jin Yonghong , Yan Mengya , Xi Yuqin , Liu Chunmei 
Published: August 2016

Purpose– The purpose of this paper is to empirically analyze the effects of stock price synchronicity and herding behavior of qualified foreign institutional investors (QFII) on stock price crash risk, especially the mediating effect of herding behavior of QFII on the relation of stock price synchronicity and stock price crash risk.Design/methodology/approach– Taking China’s A-share listed companies from 2005 to 2014 and QFII holding shares data as the research sample, this study calculates herding effect index, sock price synchronicity index and stock price crash risk index, and perform linear regression.Findings– This study concludes that, either herding behavior of QFII or the stock price synchronicity can increase the stock price crash risk. Further study reveals that, the herding behavior of QFII also improves the effect of stock price synchronicity on stock price crash risk. Namely, herding behavior of QFII acts as the mediating role between stock price synchronicity and stock price crash risk.Originality/value– This study empirically analyzes and verifies the mediating roles of herding behavior of QFII in affecting the relation of sock price synchronicity and stock price crash risk for the first time. The findings of this study contribute to the study of the role of QFII in stabilizing Chinese security market.
An empirical study on the correlation structure of credit spreads based on the dynamic and pair copula functions
Authors: Luo Changqing , Li Mengzhen , Ouyang Zisheng 
Published: August 2016

Purpose
– The purpose of this paper is to study the correlation structure of the credit spreads.

Design/methodology/approach
– The minimal spanning tree is used to find the risk center node and the basic correlation structure of the credit spreads. The dynamic copula and pair copula models are applied to capture the dynamic and non-linear correlation structure.

Findings
– The authors take the enterprise bond with trading data from January 2013 to December 2013 as the research sample. The empirical study of minimum spanning tree shows that the credit risk of corporate bonds forms a network structure with a center node. Meanwhile, the correlation between credit spreads shows dynamic characteristics. Under the framework of dynamic copula, the lower tail dependence is less than the upper tail dependence, thus, in economic boom period, the dynamic correlation is more significant than in recession period. The authors also find that the centrality of credit risk network is not significant according to the pair copula and Granger causality test. The empirical study shows that the goodness-of-fit of D vine is superior to Canonical vine, and the Granger causality test additionally proves that the center node has influence on few other nodes in the risk network, thus the center node captured by the minimum spanning tree is a weak center node, and this characteristic of credit risk network indicates that the risk network of credit spreads is generated mostly by the external shocks rather than the internal risk contagion.

Originality/value
– This paper provides new ideas for investors and researchers to analyze the credit risk correlation or contagion.
On data-driven systems and system-driven data
Authors: Van Daele Koen , Meganck Leen , Mortier Sophie 
Published: August 2016

Purpose– Over the past 20 years, heritage inventories in Flanders (Belgium) have evolved from printed books to digital inventories. The purpose of this paper is to look at this evolution and highlight the interaction between the system and its users.Design/methodology/approach– After a short introduction about the history of inventories in Flanders, this paper mainly concerns itself with the last decade. Discrete topics will be highlighted to show the effects of the interaction that has taken place.Findings– It is obvious that a system that publishes a digital inventory needs to adapt to the user requirements. But, after years of working with a digital inventory system, it has become apparent that not only has the system been developed to the users’ needs, but also that user practice and the resulting data have been shaped by the system. Seeing data projected on a common basemap has led researchers to realise how intertwined and interdependent different types of heritage can be and how much their respective methodologies can benefit from more interaction. It has become apparent that data quality is of the utmost importance, something that can only be guaranteed by data entry standards, validation tools, and a strict editing workflow. The systems that are being developed are not expected to live on forever, but the data in them is.Originality/value– This paper presents real-life use cases and practical applications of building and maintaining a large digital inventory system over the years and through changes in organisational structure and focus. It provides insights that are hard to ascertain from smaller projects due to the volumes of data that are handled.

Authors: Kondo Yasuhisa , Miki Takehiro , Kuronuma Taichi , Hayakawa Yuichi S. , Kataoka Kyoko , Oguchi Takashi 
Published: August 2016

Purpose– The purpose of this paper is to present a concurrent implementation of sustainable inventory for the UNESCO World Heritage sites of Bat, Al-Khutm and Al-Ayn in the interior of Oman.Design/methodology/approach– A digital heritage inventory (DHI) was developed through an action research to realize demands of the local agent and to co-design the solution. The Ministry of Heritage and Culture of Oman, the local agent, demanded to have archaeological information of the sites shared with foreign expeditions, which had worked at the sites for decades, for efficient heritage management, scientific research, outreach, and education. To this end, the Bat Digital Heritage Inventory (BatDHI) was implemented by a combination of network-access-ready database application, open source geographical information systems, and a web-based map service to incorporate and visualize previous works, which were concurrently cross-checked and updated by ground-truth surveys.Findings– The online inventory made it possible to update information during archaeological fieldwork in real time and accelerated the decision-making process in heritage management by prompt data updates and visualization.Research limitations/implications– The DHI is extendable for other sites or regions. It should also be considered to install Arches, an open-source suite of digital heritage inventories.Practical implications– The BatDHI was implemented through the action research mentioned in the design/methodology/approach section and yielded the implications mentioned in the findings section.Originality/value– This paper is a challenging application of transdisciplinary approach to the sustainable heritage management, in which researchers and societal stakeholders collaborate for co-design of research agendas, co-production of knowledge, and co-dissemination of outcomes.
The Arches heritage inventory and management system: a platform for the heritage field
Authors: Myers David , Dalgity Alison , Avramides Ioannis 
Published: August 2016

Purpose
– The purpose of this paper is to describe the Arches heritage inventory and management system for the benefit of practitioners working with heritage inventories. Arches is a modern software platform purpose-built for the creation and management of inventories to support effective heritage place management. The system was developed as open source software jointly by the Getty Conservation Institute (GCI) and World Monuments Fund (WMF).

Design/methodology/approach
– The paper discusses the needs and challenges addressed by the GCI and WMF in developing Arches, explains the system’s design and functionality, reports on software releases and ongoing enhancements, describes current software implementations, and concludes by discussing the role and growth of the open source community and the Arches project’s aspirations.

Findings
– The needs and challenges in the heritage field that the GCI and WMF originally identified have been confirmed through interactions between the Arches project and a range of practitioners. The suitability of Arches to address these needs is demonstrated through steady growth of the open source community and an increasing number of implementations of the Arches platform.

Practical implications
– Arches provides a purpose-built system that is freely available and ready for use. It offers a system that requires a marginal investment by organizations compared to building digital inventories from scratch. The Arches project has created an international community of information technology and heritage practitioners to share experience, knowledge, and skills to address their common challenges in dealing with digital inventories.

Originality/value
– The paper offers heritage practitioners details on a new tool for overcoming their challenges in building and managing digital heritage inventories.
Conceptualizing and measuring resistance to change in brand relationships
Authors: Ramaswami Sridhar N. , Raju Sekar , Page Dana C. 
Published: August 2016

PurposeThis research aims to examine two constructs that define loyal brand relationships – greater resistance to changing their brand beliefs and attitudes (resistance to change) and greater willingness to shun competitor brands (determinism). The paper develops and tests psychometrically sound scales to measure these two constructs and proposes and tests a model that identifies antecedent and outcome linkages between resistance and determinism and other brand relationship measures across two studies.Design/methodology/approachScale development was done following the guidelines recommended by Nunnally and Bernstein (1994) and Churchill (1979). Factor analysis was used to test scale item fit. Discriminant validity, scale reliability tests, nomological and predictive validity tests were conducted.FindingsThis study adds to the literature by identifying the specific dimensions that compose the resistance concept. It finds that strong resistance leads to determinism at the high end. It also finds that brand engagement is an outcome of resistance. In addition, three sub-components of the resistance dimension – resistance to new products that offer higher value, resistance to value improvements of competing offerings and resistance to quality deterioration for the focal or object brand – are also identified and scale items developed to measure them.Research limitations/implicationsResistance to change and determinism are less understood and researched concepts in the context of brand relationships. Further, these two dimensions are of particular importance in emerging markets such as India because of the changes taking place in these markets with the introduction of many global brands competing with traditional strong brands. For new brands, a key question is how to reduce the resistance that consumers exhibit toward trying out new brands. For existing brands, the key question is how to leverage the resistance that consumers have in trying out a new brand so that greater determinism is built and defections are minimized. This research helps answer some of these questions.Originality/valueThe primary purpose of the study was to identify the specific dimensions that compose the resistance concept. An important aspect of brand relationships is the ability to foster greater strength in the relationship. While the important of resistance has been known, a good scale to measure it has been lacking.
Constraints of cold and shade on the phenology of spring ephemeral herb species
Authors: Augspurger Carol K. , Salk Carl F. 
Published: August 2016

SummarySpring ephemeral herb species in temperate deciduous forests are active above‐ground only briefly each year. This study tested experimentally how two countervailing constraints – cold and darkness – influence the phenology of six spring herb species.Dormancy of underground structures, maintained by cold temperatures in a growth chamber, was broken at six 25‐day intervals from January or February to June in two consecutive years. Upon emergence, survival and flowering were measured on cohorts grown outdoors. Shade cloth was added at the time of normal canopy closure.Cardamine concatenata,Dicentra cucullaria,Erythronium albidumandTrillium recurvatumhad no or low 2‐year survival in the two or three earliest cohorts and no or low survival in the latest cohort, relative to their natural cohort.Allium canadenseandClaytonia virginicahad survival in all cohorts. Flowering never occurred in the first two or three cohorts for three species and never occurred or declined in later cohorts in all species.Despite widely differing emergence dates, senescence was completed within a 40‐day period soon after shade was imposed for all cohorts for all species. Consequently, leaf life span became shorter as date of emergence was delayed among cohorts.In general, the brief growth period of spring herb species is an adaptation to avoid winter cold and late‐spring canopy shade. These constraints are species‐specific and differ for survival and flowering for some species.Claytonia virginicais the most tolerant among the species to a wider range of conditions.Synthesis. Knowing that cold and shade constrain a plant's non‐dormant period is important because of the significant role plant phenology plays in responses to climate change.
Landscape spatial configuration is a key driver of wild bee demographics
Authors: Neokosmidis Lazaros , Tscheulin Thomas , Devalez Jelle , Petanidou Theodora 
Published: August 2016

AbstractThe majority of studies investigating the effects of landscape composition and configuration on bee populations have been conducted in regions of intensive agricultural production, ignoring regions which are dominated by seminatural habitats, such as the islands of the Aegean Archipelago. In addition, research so far has focused on the landscape impacts on bees sampled in cropped fields while the landscape effects on bees inhabiting seminatural habitats are understudied. Here, we investigate the impact of the landscape on wild bee assemblages in 66 phryganic (low scrubland) communities on 8 Aegean islands. We computed landscape metrics (total area and total perimeter–area ratio) in 4 concentric circles (250, 500, 750, and 1000 m) around the center of each bee sampling site including 3 habitat groups (namely phrygana, cultivated land, and natural forests). We further measured the local flower cover in 25 quadrats distributed randomly at the center of each sampling site. We found that the landscape scale is more important than the local scale in shaping abundance and species richness of bees. Furthermore, habitat configuration was more important than the total area of habitats, probably because it affects bees’ movement across the landscape. Phrygana and natural forests had a positive effect on bee demographics, while cultivated land had a negative effect. This demonstrates that phryganic specialists drive bee assemblages in these seminatural landscapes. This finding, together with the shown importance of landscape scale, should be considered for the management of wild bees with special emphasis placed on the spatial configuration of seminatural habitats.

ABSTRACTOil palm plantations have expanded rapidly in recent decades. This large‐scale land‐use change has had great ecological, economic, and social impacts on both the areas converted to oil palm and their surroundings. However, research on the impacts of oil palm cultivation is scattered and patchy, and no clear overview exists. We address this gap through a systematic and comprehensive literature review of all ecosystem functions in oil palm plantations, including several (genetic, medicinal and ornamental resources, information functions) not included in previous systematic reviews. We compare ecosystem functions in oil palm plantations to those in forests, as the conversion of forest to oil palm is prevalent in the tropics. We find that oil palm plantations generally have reduced ecosystem functioning compared to forests: 11 out of 14 ecosystem functions show a net decrease in level of function. Some functions show decreases with potentially irreversible global impacts (e.g. reductions in gas and climate regulation, habitat and nursery functions, genetic resources, medicinal resources, and information functions). The most serious impacts occur when forest is cleared to establish new plantations, and immediately afterwards, especially on peat soils. To variable degrees, specific plantation management measures can prevent or reduce losses of some ecosystem functions (e.g. avoid illegal land clearing via fire, avoid draining of peat, use of integrated pest management, use of cover crops, mulch, and compost) and we highlight synergistic mitigation measures that can improve multiple ecosystem functions simultaneously. The only ecosystem function which increases in oil palm plantations is, unsurprisingly, the production of marketable goods. Our review highlights numerous research gaps. In particular, there are significant gaps with respect to socio‐cultural information functions. Further, there is a need for more empirical data on the importance of spatial and temporal scales, such as differences among plantations in different environments, of different sizes, and of different ages, as our review has identified examples where ecosystem functions vary spatially and temporally. Finally, more research is needed on developing management practices that can offset the losses of ecosystem functions. Our findings should stimulate research to address the identified gaps, and provide a foundation for more systematic research and discussion on ways to minimize the negative impacts and maximize the positive impacts of oil palm cultivation.
A qualitative investigation of recovery after femoral fracture in Rett syndrome

Published: August 2016

AbstractBackgroundChildren with severe disability often develop osteoporosis and have an increased risk of fracture. In Rett syndrome, the prevalence of fracture is four times greater than in the general population, and the femur is commonly affected. This study used qualitative methods to investigate the regaining of mobility within 12 months following femoral fracture in Rett syndrome and parent caregiver experiences.MethodsCaregivers (n = 14) of cases registered with the Australian Rett Syndrome Database with a daughter with Rett syndrome were recruited if their daughter sustained a femoral fracture between 2009 and 2014. Median (interquartile range) age at fracture was 11 years and 4 months (8 years and 8 months to 22 years and 3 months). Qualitative methods were used to investigate parent/caregiver experiences and their daughter's recovery following fracture. Themes in the interview data were identified with thematic analysis.ResultsOperative management was chosen for those walking independently and non‐operative management for most of the remaining. All who walked independently and one of the four who required assistance recovered pre‐operative walking skills within 6 months. Themes identified by caregivers related to the complexities of pain recognition, the caregiver emotional journey and later rebuilding of relationships with service providers.ConclusionsThose who walked with assistance were vulnerable to loss of this skill. Difficulties in pain recognition increased time to diagnose fracture, and the acute episode was associated with heightened caregiver stress. Service providers can use family‐centred practice models to support the strengthening of family functioning following this acute event that is surprisingly common in those with severe disability.
A cautionary note on the use of hypervolume kernel density estimators in ecological niche modelling
Authors: Qiao Huijie , Escobar Luis E. , Saupe Erin E. , Ji Liqiang , Soberón Jorge 
Published: August 2016

AbstractBlonder et al. (, Global Ecology and Biogeography, 23, 595–609) introduced a new multivariate kernel density estimation (KDE) method to infer Hutchinsonian hypervolumes in the modelling of ecological niches. The authors argued that their KDE method matches or outperforms several methods for estimating hypervolume geometries and for conducting species distribution modelling. Further clarification, however, is appropriate with respect to the assumptions and limitations of KDE as a method for species distribution modelling. Using virtual species and controlled environmental scenarios, we show that KDE both under‐ and overestimates niche volumes depending on the dimensionality of the dataset and the number of occurrence records considered. We suggest that KDE may be a viable approach when dealing with large sample sizes, limited sampling bias and only a few environmental dimensions.

Published: August 2016

Effect of LA Wall Thickness on RF AblationIntroductionRadiofrequency (RF) ablation in thicker regions of the left atrium (LA) may require increased ablation energy in order to achieve effective transmural lesions. Consequently, many cases of recurrent atrial fibrillation (AF) postablation may be due to thicker‐than‐normal atrial tissue. The aim of this study was to test the hypotheses that patients with recurrent AF have thicker tissue overall and that electrical reconnection is more likely in regions of thicker tissue.Methods and ResultsRetrospective analysis was performed on 86 CT images acquired preoperatively from a cohort of 119 patients who had undergone RF ablation for AF. Of these, 33 patients experienced recurrence of AF within 1 year of initial treatment and 29 returned for a repeat ablation. For each patient, LA wall thickness (LAWT) was measured from the images in 12 anatomical regions using custom software. Patients with recurrent AF had larger LAWT compared to successfully treated patients (1.6 ± 0.6 mm vs. 1.5 ± 0.5 mm, P < 0.001) and reconnection was found to be at regions of thicker tissue (1.6 ± 0.6 mm, P = 0.038) compared to nonreconnected regions (1.5 ± 0.5 mm). The superior right posterior wall of the LA was significantly related to both recurrence (P = 0.048) and reconnection (P = 0.014).ConclusionIncreased LAWT has a small but significant effect on postablation recurrence and reconnection. Measures of LAWT may facilitate appropriate dosing of RF energy, but other factors will be critical in transmural lesion formation and ablation success.
