Stated preferences of Taiwanese investors for financial products
Authors: Liu Chun-Wen , Deng Chao 
Published: June 2019

PurposeThe popularity of wealth management in Taiwan has unleashed tense competition among financial advisors. Consumers are now more conscious of their financial services purchasing behavior. This paper aims to provide insights into local-specific investors’ characteristics and consumers’ financial product preferences and to introduce a different concept to identify localization-suitable products.Design/methodology/approachTo understand customers’ preferred products, the paper examines consumers’ financial behavior by analyzing preference characteristics using data collected from Taiwanese investors. The study entailed a questionnaire designed for consumers using the stated preferences method and the multinomial and nested logit models to develop preference models for consumers’ financial products. A statistical test using thet-value, likelihood andρ2to observe investor preference product reactions was also used.FindingsThe study finds that investors are sensitive to the rate of return on investments and performance changes in foreign currency, stock and mutual funds. An elasticity analysis and prediction of the market share among interactive products show that stock and mutual funds are strongly related and the rate of return on stock undoubtedly influences the market.Originality/valueThe stated preference method and inclusion of risk appetite improve our understanding of consumer choice and investors’ financial product preferences and characteristics. The results provide suitable localization product suggestions for financial institutions to help them understand their customers’ behaviors better. This paper’s results are also useful in the context of smart financial services such as financial robot technology.

AbstractOur understanding of terrestrial nitrogen (N) cycling is changing as new processes are uncovered, including the sources, turnover and losses of N from ecosystems.We integrate recent insights into an updated N‐cycling framework and discuss how a new understanding integrates eco‐evolutionary dynamics with nutrient cycling. These insights include (a) the significance of rock weathering as a biologically meaningful N source to plants and microbes; (b) the lack of consistent N limitation of organic matter decomposition by soil microbes; (c) species‐specific variation in plant N limitation; and (d) how fire effects on soil N shift with ecosystem properties.Using an eco‐evolutionary framework and revised knowledge of N cycling, we describe how (a) rock N weathering could have contributed more strongly to gradients in soil N availability than previously recognized, (b) evolution and co‐evolution of plant and soil microbial resource‐use traits underlie whether decomposition and production are N‐limited, and (c) the effects of fire on soil N pools are mediated by composition of plant species and time‐scale.Our revised framework of N cycling provides a way forward for improving biogeochemical models to more accurately estimate rates of plant production and decomposition, and total soil N.A freePlain Language Summarycan be found within the Supporting Information of this article.
Development of a PCR High‐Resolution Melt Assay for Artemisia absinthium (Wormwood) and a Triplex Assay with Two Additional “Unregulated Legal High” Species Datura stramonium (Jimson Weed) and Merremia tuberosa (Hawaiian Woodrose),
Authors: Kiesel Brianna D. , Elkins Kelly M. 
Published: June 2019

AbstractArtemisia absinthium (wormwood), a common ingredient in absinthe, contains the compound thujone, which is unregulated by the U.S. Drug Enforcement Agency. Thujone can cause an “unregulated legal high” in higher concentrations. The European Union limits thujone from Artemisia species to 35 mg/kg while the U.S. Food and Drug Administration requires less than 10 ppm to be “thujone‐free.” However, individuals can smoke or ingest A. absinthium in different forms. This study developed a polymerase chain reaction (PCR) high‐resolution melt (HRM) assay to detect and identify A. absinthium based on primer specificity, sensitivity, repeatability, and robustness. A triplex assay was performed with three “unregulated legal high” species: Datura stramonium, Merremia tuberosa, and A. absinthium; the PCR HRM assay detected and identified each plant at melt temperatures 77.42 ± 0.20°C, 83.88 ± 0.22°C, and 87.77 ± 0.15°C, respectively. The primer set developed distinguished A. absinthium from a variety of plant species and was successfully triplexed.
Exploring the intention‐behavior gap in the technology acceptance model: A mixed‐methods study in the context of foreign‐language teaching in China
Authors: Liu Haixia , Wang Lina , Koehler Matthew J. 
Published: June 2019

AbstractThis study explored the strength and mechanisms of the intention‐use link in the Technology Acceptance Model (TAM), based on data from a sample of 198 in‐service college‐level foreign‐language teachers in China. Its sequential explanatory research design involved, firstly, a quantitative approach to examine the structural relations among the TAM's variables, using path analysis on survey data; and secondly, qualitative interviews with a purposive sub‐sample of 16 of the same teachers, aimed at identifying potential influences on the intention‐behavior gap in their student‐centered technology use. Analysis of the quantitative data indicated a significant relationship between the teachers' intention to use technology and their teacher‐centered technology use of technology, but a non‐significant relationship between intention to use technology and their student‐centered technology use. The qualitative data revealed that facilitating conditions, prior experience with technology and technological pedagogical content knowledge (TPACK) were the main obstacles to the interviewees' student‐centered technology use. Other factors also played a role in educators' intention‐use gaps, including habit, beliefs in students, Chinese teaching culture and assessment pressure.
Practitioner NotesWhat is already known about this topic

TAM has been supported by a multitude of studies.

Foreign language teachers' student‐centered technology use is limited.
What this paper adds

It conceptualizes two levels of technology use behavior using TAM as framework.
It identifies an intention‐behavior gap in student‐centered technology use.
It explores external and internal constraints to student‐centered technology use.
Implications for practice and/or policy

Educational institutions need to facilitate teachers' student‐centered technology use.
Consistent training on integrating student‐centered technology use with teaching content are in need.
How cluster‐robust inference is changing applied econometrics
Authors: MacKinnon James G. 
Published: June 2019

AbstractIn many fields of economics, and also in other disciplines, it is hard to justify the assumption that the random error terms in regression models are uncorrelated. It seems more plausible to assume that they are correlated within clusters, such as geographical areas or time periods, but uncorrelated across clusters. It has therefore become very popular to use “clustered” standard errors, which are robust against arbitrary patterns of within‐cluster variation and covariation. Conventional methods for inference using clustered standard errors work very well when the model is correct and the data satisfy certain conditions, but they can produce very misleading results in other cases. This paper discusses some of the issues that users of these methods need to be aware of.
Is the Emergence of the “Fresh Prep” Food Service Provider an Entrée into Local Foods?
Authors: Henshaw Thomas L. 
Published: June 2019

AbstractDynamic changes in the structure of college and university food service have combined with a heightened public awareness of food to promote the rapid growth of farm to institution programs. This paper analyzes recent trends in food service provider/institution relationships at eight liberal arts colleges in the Great Lakes region, namely a move toward providers that freshly prepare food in house rather than purchasing processed foods. We explore the interplay between institutional and provider demands and ask the question: does the transition to a new fresh prep food service provider open the door for greater inclusion of locally sourced foods? At these institutions we find that the selection of a food service provider only moves an institution's local purchasing fractionally. Greater local sourcing requires institutional motivation, specified purchasing goals, and favorable contract structures. [farm to institution, local foods, higher education, outsourcing, contracts].
The role of university‐industry research centers in embedding foreign subsidiaries: Insights from automotive research and development in Ontario
Authors: Goracinova Elena 
Published: June 2019

AbstractRegionally embedded foreign subsidiaries have an advantage over disembedded ones. The ability to draw on local knowledge networks to create differentiating capabilities can enhance the subsidiary's influence within the multinational enterprise. A subsidiary's power is shaped by its control over external resources or skills the parent company depends on to develop new products. These local relationships are then used to bargain for further mandates, sometimes in competition with sister subsidiaries. One way in which foreign subsidiaries can deepen their connections with the local context is by collaborating in their innovative efforts with university‐based collaborative research centers (CRCs). I argue that CRCs are not a panacea when it comes to embedding the subsidiaries of foreign multinational enterprises (MNEs). A review of the literature helps identify the subsidiary‐parent relationship and industry‐academia conflicts of interest as obstacles to the development of productive relationships between subsidiaries and academia. I draw on evidence from three Ontario CRCs, with different scientific focus and stakeholders and analyze how these factors shape their behavior. The study shows that long‐term CRCs‐subsidiary relationships can be challenging to establish. This is because subsidiaries remain tightly controlled by their parent companies and cannot get access to the resources necessary to pursue ambitious innovation projects. It is also challenging for subsidiaries to form long‐term relationships with CRC researchers, who prioritize other goals such as training skilled personnel and continuing their research agenda. CRCs where 1) subsidiaries have a strong bargaining position within the MNE, and 2) academic expertise is aligned with industry needs have a greater chance to contribute to future MNE embeddedness.
Biopsychosocial barriers affecting recovery after a minor transport‐related injury: A qualitative study from Victoria

Published: June 2019

AbstractObjectiveThe aim of the study was to understand the recovery phenomena and to explore participants' perspectives on the biopsychosocial facilitators and barriers affecting their recovery after a minor transport injury.MethodsA qualitative method was used involving semi‐structured interviews with 23 participants who sustained a minor transport injury. Interviews and analysis were guided by the biopsychosocial model (BPS) of health. The outcomes were themes capturing biopsychosocial barriers to, and personal experiences of, recovery using a previously defined framework.ResultsThe themes indicate that recovery is a multifaceted phenomenon affected by comorbidities such as chronic pain, depression and anxiety. A range of subsequent complexities such as the inability to self‐care and undertaking daily domestic duties, and incapacity to participate in recreational activities were major barriers to recovery. These barriers were found to be an on‐going source of frustration, dissatisfaction and a perceived cause of depressive symptomatology in many participants. Most participants reported mixed feelings of the care received. Other common issues raised included a lack of understanding of the assessment time, regular follow‐up, guidance and on‐going support.ConclusionThis study revealed that recovery after a minor transport‐related injury was a challenging, complex, demanding and a long‐term process for the individuals in this study. Findings from this limited cohort suggested that, for participants to return to their pre‐accident health status, a more coordinated approach to information and care delivery may be required.

Published: June 2019

AbstractBackgroundOptimal management of exacerbations of chronic obstructive pulmonary disease (COPD) reduces patient morbidity and healthcare system burden. COPD guidelines, including the Global Initiative for Chronic Obstructive Lung Disease (GOLD) and the COPD‐X Plan, provide evidence‐based recommendations, but adherence in hospital practice is variable.AimsTo examine current practice in management of COPD exacerbations at an Australian teaching hospital and to compare with COPD‐X Plan recommendations.MethodsData were collected retrospectively from electronic medical records for admissions occurring during 1 May to 31 August 2016, and compared with recommendations from the COPD‐X Plan.ResultsA total of 134 patients (n = 68 females) was admitted for a COPD exacerbation during the study period. Mean age was 75.4 ± 10.2 years and 33.6% were current smokers. Airflow obstruction on spirometry was confirmed in 67.2% (mean forced expiratory volume in 1 s was 53 ± 22% predicted (1.2 ± 0.5 L)). Excellent adherence to the COPD‐X Plan was demonstrated in the ordering of chest radiographs (97%) and electrocardiograms (94%). Supplemental oxygen was appropriately provided to all patients with oxygen saturation of <88%. All patients with confirmed hypercapnic respiratory failure were managed with non‐invasive ventilation. Corticosteroids and bronchodilators were prescribed for the majority of patients. Areas of suboptimal practice included inadequate usage of arterial blood gases, excess supplemental oxygen in the absence of hypoxaemia, over‐prescription of intravenous antimicrobials, low referral rates to pulmonary rehabilitation and insufficient smoking cessation counselling.ConclusionsLevel of adherence to guideline recommendations in the management of COPD exacerbations is inadequate and further strategies are required to elevate standards of practice.
Constrained two‐dimensional guillotine cutting problem: upper‐bound review and categorization
Authors: Russo Mauro , Boccia Maurizio , Sforza Antonio , Sterle Claudio 
Published: June 2019

AbstractIn the two‐dimensional (2D) cutting (2DC) problem, a large rectangular sheet has to be dissected into smaller rectangular pieces with the aim of maximizing the total profit associated with the extracted pieces. When the number of copies of each piece to be extracted is bounded, it is referred to as constrained 2DC (C2DC) problem. The C2DC has been widely studied by the operations research community for its applications and theoretical issues. In this work, we recall the best exact and heuristic solving approaches for the C2DC and we provide a review and a categorization of the available upper bounds. We also discuss improvements and combinations of these upper bounds and give directions for their effective exploitation. Finally, we demonstrate the loss of accuracy of several exact methods present in literature because of the effect of the used antiredundancy strategies on the implemented bounding criteria. This work, based on more than 90 contributions, has a twofold target. For researchers working in C2DC, it provides a useful insight on the topic. For expert practitioners, it represents a systematic collection of the main findings and achievements, posing also the basis for future research.
Competition model and coordination mechanism considering strategic customer behavior under vendor‐managed inventory
Authors: Cai Jianhu , Zhou Qian , Sun Jianyue , Hu Xiaoqing , Feng Cuiying , Li Xuejiao 
Published: June 2019

AbstractThis paper proposes the vendor‐managed inventory (VMI) decision model that considers strategic customer behavior. Decision differences between the Stackelberg game equilibria and the supply chain (SC) coordination are compared under the VMI mode. A comparison of the optimal decisions under the VMI mode and the retailer‐managed inventory (RMI) mode is made. The SC members’ preferences for the two inventory modes are obtained under different wholesale price conditions. Then, the option contract is introduced to coordinate the SC, and possible allocation schemes of the coordinated expected profit between the SC members are discussed. Through a reasonable design of the option contract, a Pareto improvement can be achieved with the SC being coordinated. All of our findings are illustrated using numerical examples.
Examining Differential Rater Functioning Using a Between‐Subgroup Outfit Approach
Authors: Wind Stefanie A. , Sebok‐Syer Stefanie S. 
Published: June 2019

AbstractWhen practitioners use modern measurement models to evaluate rating quality, they commonly examine rater fit statistics that summarize how well each rater's ratings fit the expectations of the measurement model. Essentially, this approach involves examining the unexpected ratings that each misfitting rater assigned (i.e., carrying out analyses of standardized residuals). One can create plots of the standardized residuals, isolating those that resulted from raters’ ratings of particular subgroups. Practitioners can then examine the plots to identify raters who did not maintain a uniform level of severity when they assessed various subgroups (i.e., exhibited evidence of differential rater functioning). In this study, we analyzed simulated and real data to explore the utility of this between‐subgroup fit approach. We used standardized between‐subgroup outfit statistics to identify misfitting raters and the corresponding plots of their standardized residuals to determine whether there were any identifiable patterns in each rater's misfitting ratings related to subgroups.
Scale Alignment in Between‐Item Multidimensional Rasch Models
Authors: Feuerstahler Leah , Wilson Mark 
Published: June 2019

AbstractScores estimated from multidimensional item response theory (IRT) models are not necessarily comparable across dimensions. In this article, the concept of aligned dimensions is formalized in the context of Rasch models, and two methods are described—delta dimensional alignment (DDA) and logistic regression alignment (LRA)—to transform estimated item parameters so that dimensions are aligned. Both the DDA and LRA methods are applied to real and simulated data, and it is demonstrated that both methods are broadly effective for achieving aligned scales. The routine use of scale alignment methods is recommended prior to comparing scores across dimensions.
Nasal dorsum augmentation using soft tissue filler injection

Published: June 2019

AbstractBackgroundSoft tissue filler injection is a common procedure for augmentation rhinoplasty. Various techniques for augmenting the nasal dorsum using a soft tissue filler have been attempted considering the size of the needle, the anatomical layer where the filler is injected, and the vascular distribution. The purpose of this paper was to evaluate the course of the dorsal nasal artery in patients scheduled for nasal augmentation using a soft tissue filler and to propose a method of nasal augmentation that minimizes vessel damage during soft tissue filler injection by confirming the distribution pattern of blood vessels through ultrasound.MethodsPatients underwent augmentation rhinoplasty using a soft tissue filler. All patients underwent ultrasound examination before the filler injections.ResultsFrom July to September 2018, ultrasound studies were conducted before augmentation rhinoplasty in 50 consecutive patients. Forty patients (80%) had a well‐known lateral arterial pathway, while in 10 patients (20%), the dorsal nasal artery was found at the midline of the nose. In four cases (8%), the artery travelled just beneath the preperiosteal layer, which is under the nasalis muscle. Additionally, in seven cases (14%), the dorsal nasal artery coursed superficially, just beneath the subdermal layer.ConclusionInjecting the filler into the preperiosteal layer either via a needle or cannula is considered relatively safe but there remains the possibility of vascular compromise. Using a large diameter cannula and injecting the filler into the preperiosteal layer using a gentle approach may be the safest approach.
Indian English in theory and action
Authors: Mesthrie Rajend 
Published: June 2019

AbstractThis tribute to the work of Braj B. Kachru covers three themes. First, I present an overview of Kachru's career and contribution to the field of world Englishes (WE) and language contact. In the second and main section I present an overview of Indian English – Language and culture, a booklet in the Lonely Planet language products series from 1968 (Lonely Planet, 2008). I argue that this popular piece of work is a fitting – if unwitting – tribute to Kachru's work in bringing to life the features of Indian English and related varieties for practical (and even commercial), rather than academic purposes. In the final section I reflect briefly on newer models in WE studies in relation to Kachru's oeuvre.
Singularity Analysis on a Special Class of Cable-Suspended Parallel Mechanisms With Pairwise Cable Arrangement and Actuation Redundancy

Abstract
This paper presents a singularity study on a special class of spatial cable-suspended parallel mechanisms (CSPMs) with merely three translational degrees of freedom using redundant actuators. This paper focuses on the CSPMs that have the capability to perform the purely translational movement with pairwise cables as parallelograms. There are two types of singularity to be discussed, which result from dynamic equations of CSPMs and the parallelogram constraint of pairwise cables. To ensure three-translational dofs without rotation of the end-effector, the matrix formed by normals of the planes based on each pairwise cables should maintain in full rank. In the case study, four typical designs of CSPMs with a planar end-effector and a spatial end-effector are discussed to clarify and conclude the singularity features of CSPMs with actuation redundancy. The results show that for some architectures there exist both types of singularity for redundantly actuated CSPMs with pairwise cables but for some other architectures the redundant actuation exerts no effect on the singularity issue.
