Optimization Mechanism

Conventional recommender systems are designed to achieve high prediction accuracy by recommending items expected to be the most relevant and interesting to users. Therefore, they tend to recommend only the most popular items. Studies agree that diversity of recommendations is as important as accuracy because it improves the customer experience by reducing monotony. However, increasing diversity reduces accuracy. Thus, a recommendation algorithm is needed to recommend less popular items while maintaining acceptable accuracy. This work proposes a two-stage collaborative filtering optimization mechanism that obtains a complete and diversified item list. The first stage of the model incorporates multiple interests to optimize neighbor selection. In addition to using conventional collaborative filtering to predict ratings by exploiting available ratings, the proposed model further considers the social relationships of the user. A novel ranking strategy is then used to rearrange the list of top-N items while maintaining accuracy by (1) rearranging the area controlled by the threshold and by (2) maximizing popularity while maintaining an acceptable reduction in accuracy. An extensive experimental evaluation performed in a real-world dataset confirmed that, for a given loss of accuracy, the proposed model achieves higher diversity compared to conventional approaches.

Rigorous Procedure

Abstract Scientifically validated tools to assess housing accessibility for older adults in Japan have been lacking. To address this, a rigorous procedure of adapting an existing housing assessment tool—the Housing Enabler, developed in Sweden—for valid use in Japan was conducted. The original tool was translated into the Japanese language, using established translation procedures. In the process, researchers checked the appropriateness of technical terms and adjusted specifications to be in accordance with Japanese standards. An expert panel approach was used to validate the content of the Japanese Housing Enabler. Thirteen certified occupational therapists, architects and care-managers (average experience=14.5 years) participated as experts in the content validity study. They rated each item with regard to relevance for assessing housing accessibility in Japan, on a scale from 1(=Not relevant) to 4(= Highly relevant). They suggested adjustments and additions that they found to be relevant to capture particularities of Japanese housing and building design. After individual ratings, the experts gathered for consensus discussions on suggested revisions of the item list. As a result, the number of items was substantially increased (from 161 to 283). A content validity index (CVI) was calculated for each item (i.e., the proportion of experts rating the relevance as at least 3). Using a recommended threshold of CVI ≥0.78, more than 90% of the items were considered relevant, thus supporting the content validity. However, the large amount of items might jeopardize the feasibility of the instrument. Further studies are needed to evaluate feasibility, criterion-related validity and aspects of reliability.

High Performance Organization

Purpose One of the most important characteristics of high-performance organizations is that these organizations always aim at servicing their customers as best as possible. In practice, this means that the employees of these organizations have to behave toward customers in such a way that these customers are not only fully satisfied but also become loyal to the organization. The purpose of this paper is to look at the concrete behaviors that are needed to create this customer loyalty. Design/methodology/approach From a literature review the items that potentially are of influence on creating customer loyalty and customer intimacy were identified, based on a previous validated questionnaire while adding additional items. These items were subsequently validated in practice with a questionnaire distributed among people who are in daily life regular customers of organizations. Findings The research results show that there are eight behavioral factors of importance to create customer loyalty and customer intimacy: first, service quality delivered by employees; second, capability of employees to deliver high quality; third, empathy of employees toward customers’ wishes and needs; fourth, understanding of employees of customers’ needs; fifth, responsiveness of employees toward the needs of customers; sixth, courtesy of employees toward customers; seventh, service manner of employees; and finally, trust customers place in employees. Research limitations/implications The implication of this research is that, now that the behavioral factors are known, an organization can make sure its employees focus on displaying these behaviors toward customers consistently over time, in order to make sure customers will experience the organization as a high-performance organization and will feel loyalty toward the organization. Originality/value The research described in this paper adds to the literature in the sense that it encompasses previous research into once item list and specifically looks at behaviors that create excellent service and thereby customer loyalty and customer intimacy, both concepts that go beyond the much researched topic of customer satisfaction.

Recently, BIM (Building Information Modeling) became mandatory in Korea, and BIM started to be implemented in construction area. It is a design tool for maximizing the efficiency of design, construction, and maintenance throughout the entire lifecycle, but there are not many studies about the demolition wastes (DW) in the demolition stage. This study gathered basic data concerning the development of a database of DW disposed in the demolition stage using BIM-based building material database. For this, a BIM software, ARCHICAD, and construction material categories of the item list system of the PPS (Public Procurement Service) were analyzed to select major building materials. Based on the analysis, the disposal routes were analyzed considering the characteristics of DW. The database of DW was developed by examining the disposal routes of 52 major construction materials selected according to the characteristics of each material during demolition and selecting 7 major DW.

Abstract A 250-concept list was established for the purposes of an ongoing lexically-based study of Sino-Tibetan. This paper supplies the Old Chinese version of the list, in the Old Chinese reconstruction of Baxter and Sagart 2014. Chinese words attested in pre-Han times were selected based on their meaning as given in major lexica such as the Hànyǔ Dà Zìdiǎn. At times more than one OC item was found to match a concept in the list without it being clear which of the terms was the oldest. In such cases all the candidates were retained. As a result, the Old Chinese version of the list contains 301 words.

Experience Measure

We developed a chronic obstructive pulmonary disease (COPD) patient-reported experience measure (PREM-C9). 174 patients with COPD (86 [49%] with a confirmed diagnosis and 88 [51%] with a self-reported diagnosis of COPD) completed a 38-item list, COPD Assessment Test (CAT) and Hospital Anxiety and Depression Scale (HADS). Hierarchical and Rasch analysis produced a 9-item list (PREM-C9). It demonstrated fit to the Rasch model (χ² p=0.33) and correlated moderately with CAT (r=0.42), HAD-anxiety (r=0.30) and HAD-depression (r=0.41) (p<0.05). A substudy confirmed its ability to detect change prepulmonary and postpulmonary rehabilitation. The PREM-C9 is a simple, valid measure of experience of patients living with COPD, validated in this study population with mild to very severe disease; it may be a useful measure in research and clinical audits.

Abstract Background The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group is developing computerized adaptive testing (CAT) versions of each scale of the EORTC Quality of Life Questionnaire (EORTC QLQ-C30). This study aims to develop an item bank for the EORTC QLQ-C30 cognitive functioning scale, which can be used for CAT. Methods The complete developmental approach comprised four phases: (I) conceptualization and literature search, (II) operationalization, (III) pretesting, and (IV) field-testing. This paper describes phases I–III. I) A literature search was performed to identify self-report instruments and items measuring cognitive complaints on concentration and memory. II) A multistep item-selection procedure was applied to select and generate items that were relevant and compatible with the ‘QLQ-C30 item style.’ III) Cancer patients from different countries evaluated the item list for wording (ie, whether items were difficult, confusing, annoying, upsetting or intrusive), and whether relevant issues were missing. Results A list of 439 items was generated by the literature search. In the multistep item-selection procedure, these items were evaluated for relevance, redundancy, clarity, and response format, resulting in an list of 45 items. A total of 32 patients evaluated this item list in the pretesting phase, resulting in a preliminary list of 44 items. Conclusion Phase I–III resulted in an item list of 44 items measuring self-reported cognitive complaints that was endorsed by international experts and cancer patients in several countries. This list will be evaluated for its psychometric characteristics in phase IV.
