PurposeThe purpose of the present study was to evaluate the effect of air mattress pressure on sleep quality.Design/methodology/approachTen young healthy males participated in all hard surface [AH], shoulder soft [SS] and shoulder and hip soft mattress [SHS] conditions. The surface pressure for SS and SHS were set at their preferred levels.FindingsThe results showed that sleep efficiencies were over 95% for all the three conditions; there were no significant differences in individual sleep variables among the three conditions, but overall sleep quality was better for SS than AH (p = 0.065); heart rates during sleep was greater for AH than the other two conditions (p < 0.1); and a stronger relationship between clothing and bed microclimate humidity were found for SS and SHS than that for AH.Research limitations/implicationsThese results indicated that the both pressure relief air mattresses that were set at their own preferred levels provided high quality sleep with no marked differences.Practical implicationsAir pressure relief mattresses can improve sleep quality of healthy individuals during sleep at night. The results can be used to understand appropriate pressure distribution on surface mattress according to body region, and also to develop algorithms to provide optimum sleep using mattresses with surface pressure control by body region.Originality/valueThe present study found that the shoulder and/or hip pressure relief air mattresses that were set at their own preferred levels provided high quality sleep with no marked differences.

Thermal comfort is crucial in satisfaction and maintaining quality sleep for occupants. In this study, we investigated the comfort temperature in the bedroom at night and sleep quality for Indonesian students during summer and winter. Eighteen male Indonesian students aged 29 ± 4 years participated in this study. The participants had stayed in Japan for about six months. We evaluated the sleep parameters using actigraphy performed during summer and winter. All participants completed the survey regarding thermal sensation, physical conditions, and subjective sleepiness before sleep. The temperature and relative humidity of participants’ bedrooms were also measured. We found that the duration on the bed during winter was significantly longer than that during summer. However, sleeping efficiency during winter was significantly worse than that during summer. The bedroom temperature of the participants was in the range of comfort temperature in Indonesia. With the average bedroom air temperature of 22.2 °C, most of the participants still preferred “warm” and felt “slightly comfortable” during winter. The average comfort temperature each season calculated using the Griffiths method was 28.1 °C during summer and 23.5 °C during winter. In conclusion, differences in adaptive action affect bedroom thermal conditions. Furthermore, habits encourage the sleep performance of Indonesian students.

PurposeThrough a two-stage survey, this paper examines how researchers judge the quality of answers on ResearchGate Q&A, an academic social networking site.Design/methodology/approachIn the first-stage survey, 15 researchers from Library and Information Science (LIS) judged the quality of 157 answers to 15 questions and reported the criteria that they had used. The content of their reports was analyzed, and the results were merged with relevant criteria from the literature to form the second-stage survey questionnaire. This questionnaire was then completed by researchers recognized as accomplished at identifying high-quality LIS answers on ResearchGate Q&A.FindingsMost of the identified quality criteria for academic answers—such as relevance, completeness, and verifiability—have previously been found applicable to generic answers. The authors also found other criteria, such as comprehensiveness, the answerer's scholarship, and value-added. Providing opinions was found to be the most important criterion, followed by completeness and value-added.Originality/valueThe findings here show the importance of studying the quality of answers on academic social Q&A platforms and reveal unique considerations for the design of such systems.

The Impact

Web Real-Time Communication (WebRTC) combines a set of standards and technologies to enable high-quality audio, video, and auxiliary data exchange in web browsers and mobile applications. It enables peer-to-peer multimedia sessions over IP networks without the need for additional plugins. The Opus codec, which is deployed as the default audio codec for speech and music streaming in WebRTC, supports a wide range of bitrates. This range of bitrates covers narrowband, wideband, and super-wideband up to fullband bandwidths. Users of IP-based telephony always demand high-quality audio. In addition to users’ expectation, their emotional state, content type, and many other psychological factors; network quality of service; and distortions introduced at the end terminals could determine their quality of experience. To measure the quality experienced by the end user for voice transmission service, the E-model standardized in the ITU-T Rec. G.107 (a narrowband version), ITU-T Rec. G.107.1 (a wideband version), and the most recent ITU-T Rec. G.107.2 extension for the super-wideband E-model can be used. In this work, we present a quality of experience model built on the E-model to measure the impact of coding and packet loss to assess the quality perceived by the end user in WebRTC speech applications. Based on the computed Mean Opinion Score, a real-time adaptive codec parameter switching mechanism is used to switch to the most optimum codec bitrate under the present network conditions. We present the evaluation results to show the effectiveness of the proposed approach when compared with the default codec configuration in WebRTC.

Purpose Visit time is a crucial aspect of patient–physician interaction; its inadequacy can negatively impact the efficiency of treatment and diagnosis. In addition, visit time is a fundamental demand of patients, and it is one of the rights of every patient. The purpose of this paper is to determine factors influencing the consultation length of physicians and to compare consultation length in different countries. Design/methodology/approach MEDLINE (PubMed), Web of Science, Cochrane, ProQuest, Scopus, and Google Scholar were searched. In addition, references of references were checked, and publication lists of individual scholars in the field were examined. We used data sources up to June 2018, without language restriction. We used a random-effects model for the meta-analyses. Meta-analyses were conducted using Comprehensive Meta-Analysis Version (CMA) 3.0. Findings Of 16,911 identified studies, 189 studies were assessed of which 125 cases (67 percent) have been conducted in the USA. A total of 189 studies, 164 (86.77 percent) involved face-to face-consultations. The effects of three variables, physician gender, patient gender, and type of consultation were analyzed. According to moderate and strong evidence studies, no significant difference was found in the consultation lengths of female and male doctors (Q=42.72, df=8, I2=81.27, p=0.891) and patients’ gender (Q=55.98, df=11, I2=80.35, p=0.314). In addition, no significant difference was found in the telemedicine or face-to-face visits (Q=41.25, df=5, I2=87.88, p=0.170). Originality/value In this systematic review and meta-analysis, all of physicians’ visits in 34 countries were surveyed. The evidence suggests that specified variables do not influence the length of consultations. Good relationship is essential to a safe and high-quality consultation and referral process. A high-quality consultation can improve decisions and quality of visits, treatment effectiveness, efficiency of service, quality of care, patient safety and physician and patient satisfaction.

Purpose Patients with chronic obstructive pulmonary disease (COPD) suffer from many health problems including poor sleep. This paper aims to evaluate the relationship between diet quality indices (DQIs) and sleep quality in COPD. Design/methodology/approach The current cross-sectional study was carried on 121 COPD patients. Subjective quality of sleep was determined by Pittsburgh Sleep Quality Index (PSQI) and categorized into “poor” and “good” sleep quality. Dietary history was assessed by the DQIs. Disease status was categorized according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) Guidelines. Findings In total, 103 men and 18 women with a mean age of 66.1 ±10.9 were studied. The subjects were categorized into four groups based on GOLD; 3.3% of subjects were at Stage 1, 38% in Stage 2, 38% in Stage 3 and 20.7% in Stage 4. In total, 38% of subjects were good, and 62% were bad sleepers according to PSQI score. There was no significant relationship between the severity of COPD and PSQI score. We observed a significant inverse relation between PSQI total score and Mediterranean diet (MED) scale, Healthy Eating Index (HEI)-2010 and HEI-2005 (p = 0.024, 0.037 and 0.024, respectively) in males. Originality/value This study showed a high prevalence of poor quality of sleep and sleep disturbances among COPD patients. There was an inverse association between PSQI and sleep disorders and DQIs scores in COPD patients. Regardless of the severity of airflow obstruction, poor diet quality may constitute a risk factor for sleep quality.

Purpose – The importance of partnerships to organizational success has increased considerably the past decennia and many organizations strive at creating high-performance partnerships (HPPs). For this to happen, organizations in the partnerships have to be of high quality and their collaborations should be world-class. Whereas the factors that create high-performance organizations (HPO) are by now reasonably well established, the HPP factors are still unclear. The purpose of this paper is to develop a scale for measuring the factors of importance for creating and maintaining HPPs, and relates these factors to the factors of the HPO framework and to the success of the partnership. Design/methodology/approach – During a literature study ten potential factors of importance for creating and maintaining HPPs were identified. These potential factors were put in a questionnaire, together with the factors that create the HPO and the factor that measures the success of the partnership. This questionnaire was administered to a cable company, which was working on becoming an HPO, and four of its main suppliers. The data were subjected to a factor analysis which yielded a HPP framework consisting of three factors and 19 underlying characteristics. In addition, these HPP factors were put in a regression analysis with the factors of the HPO framework and the success of the partnership factor. Findings – The research results show a strong relationship between three HPP factors, the five HPO factors, and the success of a partnership factor. Research limitations/implications – This research adds to the literature by extending the concept of HPOs to the value chain these HPOs operate in. Thus the research into the factors of successful partnerships has been brought forward. The practical benefit of the research is that organizations can use the HPP factors to increase the quality of the partnerships they have with their suppliers and customers. Originality/value – There is much literature on partnerships but not so much on partnerships between organizations which strive to become a HPOs, and in the process need to create partnership of high quality.

The Relationship

Purpose – The purpose of this paper is to investigate the boundary conditions in the relationship between feedback-seeking behavior (FSB) and work performance. The authors hypothesized that the positive influence of employees’ FSB on their work performance is influenced by perceived quality of feedback. The authors also expected that employees’ trust in their supervisors moderated the interaction between their FSB and perceived feedback quality. Design/methodology/approach – Data were collected from 202 employees in South Korea. A hierarchical multiple regression analysis was performed to test the hypothesis. Findings – The results showed that while employees’ FSB was positively related to work performance, the influence was stronger for employees who perceived they were receiving high quality of feedback from supervisors. The authors also found that the moderating effect of feedback quality on the relationship between FSB and work performance was stronger when employees had high levels of trust in their supervisors. Practical implications – The findings suggest that if managers wish to encourage employees to achieve work goal and desirable performance levels by actively engaging in FSB, they should pay more attention to providing high quality of feedback and building trust with employees. Originality/value – This study contributes to expand the understanding of FSB-work performance relationship by verifying the boundary conditions, which suggests the importance of examining the moderating factors in the FSB mechanism.

Background: Several studies on the effects of music on sleep disorders have demonstrated that music listening can improve sleep quality in patients with sleep disorders. To our knowledge, nevertheless, none of them have elucidated the characteristics of such music itself.Objective: The purpose of the present study was to elucidate the characteristics of the types of music that improve sleep quality.Methods: In twenty five tracks used in the previous study, we calculated four analysis indicators: scaling exponent of the spectrum of melody's zero-crossings, redundancy of note values, density of notes and tempo.Results: The characteristics of music to improve sleep quality were slow tempo, small change of rhythm, and moderate pitch variation of melody. Based on the results derived from cluster analysis, the music pieces studied were largely categorized into 3 groups. A comparison of these 3 groups showed no significant differences with respect to the scaling exponent of the melody and the density of notes, whereas it showed significant differences with respect to the redundancy of note values and tempo.Conclusions: Our study revealed several characteristics of the types of music that improve sleep quality. The identification of these characteristics contributes to providing personalized music therapy to patients.
