Studies on online social relationships have focused on how Internet use is associated with sociability, but have not compared the quality of online with offline relationships. On the other hand, studies on adolescent friendship formation have used school samples disregarding the Internet as a new social context for it. We took a different…

establish eLoyalty. The target population of this study was South African tourism accommodation establishments who advertised on online tourism portals during 2005. A personalised branded HTML email with a clickable link to the online survey was mailed to all respondents. One hundred and nine valid responses were received. A multi-item questionnaire was used to measure the relationship between eService quality, eValue, eSatisfaction and eLoyalty pertaining to online tourism portals utilised by the respondents. The findings imply that online tourism portals would increase their eLoyalty (and thus increase profits if they first satisfied their suppliers’ needs by providing them with a secure, visually pleasing user interface with which they could identify. Secondly, there is a need for online tourism portals to provide services that add value, making it easy for suppliers to add and change details on their own pages, as well as ensuring that their suppliers receive a substantial income stream through the portal.

Previous research found that relationship quality (RQ) for intimate couples may be adversely effected in times of stress, potentially decreasing marital satisfaction up to 36% during a four-year period for high stress couples. Previous research indicated family values (FV) may mediate RQ in stressful times; however, no research has examined this…
With the diffusion of networked technology, personal relationships can be easily formed and maintained online today. Similar to a face-to-face situation, conflict is also seen in these online relationships. Early theories suggested that computer-mediated communication (CMC) tends to increase conflicts because of the lack of social-context cues, and CMC is not rich enough to manage conflict. As CMC has become part of our daily life, we often face conflict online, and thus we need to understand how people manage conflict online. This study explored how online users manage interpersonal conflict. Self-report survey data from 159 university students were analyzed to examine their conflict-management styles in association with the perceived closeness of the online relationship and a future intention toward the relationship. The results indicated that online users select cooperative management styles to handle conflict in their close relationships. In addition, online users avoid less cooperative styles when they want to continue the relationship.

Full Text Available The purpose of this study is to investigate the relationship among online retailing information quality, e-satisfaction, e-trust and young generation customer’s commitment in mainland China. The study variables have considerable importance in e-tailers performance. The data were collected based on a sample of 383 students from Chinese universities during the first quarter of 2014. We used confirmatory factor analysis (CFA and structural equation modeling (SEM to evaluate the hypotheses about the relationship among model constructs. Thus, all the hypotheses developed in the study were positively confirmed except one. Therefore, the investigated variables are reinforcing the theory and previous research in this field. This study reveals interesting implications of information quality, e-satisfaction, e-trust and customers commitment that are useful to both academicians and practitioners.
Full Text Available Information technology has affected various sectors including the education sector. In the sector, information technology has brought us long distance education, which relies heavily on the use of e-learning management system. In Indonesia, Bina Nusantara University is the first and foremost long distance education institution. The institution has been developing and using an e-learning management system for a number of years. This work intends to evaluate to which extent the system is able to enhance e-learning experiences. We adopted the DeLone and McLean’s Information System success model and empirically measured the relation between the aspects of system quality, information quality, service quality, user satisfaction, and net benefits. From a population of the size 311 students, we have collected 149 responses using questionnaires by randomly selecting the participating students. The responses were used to establish a multi-variate regression model where the relationships were established. The model suggested that information quality, system quality, and service quality had positive impacts on user satisfaction with the p-values of 0.014, 0.014, and 0.000 respectively. In addition, the study also found that user satisfaction was strongly and positively affected by the net benefits.

Over the past decade, technology has become increasingly important in the lives of adolescents. As a group, adolescents are heavy users of newer electronic communication forms such as instant messaging, e-mail, and text messaging, as well as communication-oriented Internet sites such as blogs, social networking, and sites for sharing photos and videos. Kaveri Subrahmanyam and Patricia Greenfield examine adolescents' relationships with friends, romantic partners, strangers, and their families in the context of their online communication activities. The authors show that adolescents are using these communication tools primarily to reinforce existing relationships, both with friends and romantic partners. More and more they are integrating these tools into their "offline" worlds, using, for example, social networking sites to get more information about new entrants into their offline world. Subrahmanyam and Greenfield note that adolescents' online interactions with strangers, while not as common now as during the early years of the Internet, may have benefits, such as relieving social anxiety, as well as costs, such as sexual predation. Likewise, the authors demonstrate that online content itself can be both positive and negative. Although teens find valuable support and information on websites, they can also encounter racism and hate messages. Electronic communication may also be reinforcing peer communication at the expense of communication with parents, who may not be knowledgeable enough about their children's online activities on sites such as the enormously popular MySpace. Although the Internet was once hailed as the savior of education, the authors say that schools today are trying to control the harmful and distracting uses of electronic media while children are at school. The challenge for schools is to eliminate the negative uses of the Internet and cell phones in educational settings while preserving their significant contributions to education and social

The increase adoption of Internet among young users in Malaysia provides high prospect for online seller. Young users aged between 18 and 25 years old are important to online sellers because they are actively involved in online purchasing and this group of online buyers is expected to dominate future online market. Therefore, examining online sellers’ website quality and online buyers’ purchase intention is crucial. Based on the Theory of planned behavior (TPB), a conceptual model of online sellers’ website quality and purchase intention of online buyers was developed. E-tailQ instrument was adapted in this study which composed of website design, reliability/fulfillment, security, privacy & trust, and customer service. Using online questionnaire and convenience sampling procedure, primary data were obtained from 240 online buyers aged between 18 to 25 years old. It was discovered that website design, website reliability/fulfillment, website security, privacy & trust, and website customer service positively and significantly influence intention of online buyers to continuously purchase via online channels. This study concludes that online sellers’ website quality is important in predicting online buyers’ purchase intention. Recommendation and implication of this study were discussed focusing on how online sellers should improve their website quality to stay competitive in online business.

Analyzing content generated by users of social network sites has been shown to be beneficial across a number of disciplines. Such analysis has revealed the precise behavior of users that details their distinct patterns of engagement. An issue is evident whereby without direct engagement with end users, the reasoning for anomalies can only be the subject of conjecture. Furthermore, the impact of engaging in social network sites on quality of life is an area which has received little attention. Of particular interest is the impact of online social networking on older users, which is a demographic that is specifically vulnerable to social isolation. A review of the literature reveals a lack of knowledge concerning the impact of these technologies on such users and even less is known regarding how this impact varies across different demographics. The objective of our study was to analyze user interactions and to survey the attitudes of social network users directly, capturing data in four key areas: (1) functional usage, (2) behavioral patterns, (3) technology, and (4) quality of life. An online survey was constructed, comprising 32 questions. Each question directly related to a research question. Respondents were recruited through a variety of methods including email campaigns, Facebook advertisements, and promotion from related organizations. In total, data was collected from 919 users containing 446 younger and 473 older users. In comparison to younger users, a greater proportion of older users (289/473, 61.1% older vs 218/446, 48.9% younger) (PFacebook had either a positive or huge impact on their quality of life. Furthermore, a greater percentage of older users strongly agreed that Facebook strengthened their relationship with other people (64/473, 13.5% older vs 40/446, 9.0%younger) (P=.02). In comparison to younger users, a greater proportion of older users had more positive emotions-classified as slightly better or very good-during their engagement with

Online drug markets are expanding the boundaries of drug supply including the sale and purchase of image and performance enhancing drugs (IPEDs). However, the role of the internet in IPED markets, and in particular the ways in which these substances are supplied via the surface web, has rarely been considered. This article examines the online IPED market in order to inform drug policy and to provide a nuanced understanding of retailers involved, particularly exploring the relationship between buyers and sellers. This paper is based on two extensive research projects conducted in the Netherlands and Belgium. The first project focuses on muscle drugs and is based on 64 IPED dealing cases, semi-structured interviews with authorities (N=32), and dealers (N=15), along with an analysis of 10 steroid-selling websites. The second research project primarily focuses on weight loss drugs and sexual enhancers in the Netherlands, and relies on interviews with authorities (N=38), suppliers (N=30), and consumers (N=10), analysis of 69 criminal case files, and an online analysis. In the literature, the illicit online sale of IPEDs is generally associated with illegal online pharmacies that try to mislead buyers. While confirmed in our research, we also illustrate that there are online suppliers who invest in customer relationships and services, and that users are aware of the illegal nature of their business. These e-vendors incorporate a 'social supply business model' by providing the best possible service to their customers and attempting to minimise risks in order to attract, satisfy and maintain customers. As it is likely that users will continue to make use of the internet to order IPEDs, regardless of closing down selling websites, it is first of all important to counteract these online sources by educating all types of consumers and providing harm reduction services.

With the growing popularity of online social network,trust plays a more and more important role in connecting people to each other.We rely on our personal trust to accept recommendations,to make purchase decisions and to select transaction partners in the online community.Therefore,how to obtain trust relationships through mining online social networks becomes an important research topic.There are several shortcomings of existing trust mining methods.First,trust is category-dependent.However,most of the methods overlook the category attribute of trust relationships,which leads to low accuracy in trust calculation.Second,since the data in online social networks cannot be understood and processed by machines directly,traditional mining methods require much human effort and are not easily applied to other applications.To solve the above problems,we propose a semantic-based trust reasoning mechanism to mine trust relationships from online social networks automatically.We emphasize the category attribute of pairwise relationships and utilize Semantic Web technologies to build a domain ontology for data communication and knowledge sharing.We exploit role-based and behavior-based reasoning functions to infer implicit trust relationships and category-specific trust relationships.We make use of path expressions to extend reasoning rules so that the mining process can be done directly without much human effort.We perform experiments on real-life data extracted from Epinions.The experimental results verify the effectiveness and wide application use of our proposed method.

Background The quality of social relationships and social support appears to be associated with physical health outcomes and sleep quality. Almost all previous research in this area focuses on positive aspects of relationships. Purpose The present study thus intended to examine the links between supportive, aversive, ambivalent, and indifferent network ties and sleep quality. Methods Relationship data, PSQI-assessed sleep quality, and depression were examined in 175 middle-aged and older adults. Results Consistent with hypotheses, supportive ties were positively related to sleep quality, while aversive ties predicted worse sleep quality; associations that were primarily seen for close relationships. Ambivalent and indifferent ties were not significant predictors of sleep quality. Importantly, depression was found to mediate the link between relationship quality and sleep quality. Conclusions These data suggest the more specific types of social relationships that may be linked to poor sleep quality, and that depression appears to underlie these associations. PMID:25976874

Past research on online relationships has predominantly been concerned with how the quality of online relationships compares with offline relationships. This research has been more concerned with the medium itself than with the meanings that users construct around their interpersonal interactions within this medium. The current paper seeks to redress this imbalance by exploring the ways that available social cues are used to shape the meanings of online relationships. Sixty Internet users, ranging in age from 19-51 years, were interviewed about their online relationships. It was found that ideals that are important in traditional relationships, such as trust, honesty, and commitment are just as important in online relationships; however, the cues that signify these ideals vary.

Full Text Available As online media has become an increasingly important part of youths’ daily lives, it is critical for the field to explore questions related to youth online media use in order to support youth workers, youth development practice and programming. Using a national sample of youth age 13-22 (N = 585, the current study explored demographic differences in youth online media use, and examined associations between youth demographics, parental monitoring, parent-child relationship quality, and likelihood of being a frequent user of online activities. Although youth reported being frequent users of online media, Internet use was not the same for all youth. Online media use differed significantly by youth age, gender, race, and family relationship quality. The findings remind the field to consider the young people we are working with and how they use online media in their daily lives.

Increased availability of medical information on the Internet empowers patients to look up answers to questions about their medical conditions. However, the quality of medical information available on the Internet is highly variable. Various tools for the assessment of online medical information have been developed and used to assess the quality and accuracy of medical web sites. In this study we used the LIDA tool (Minervation) to assess the quality of pediatric patient information on the AAOS (American Academy of Orthopaedic Surgeons) and POSNA (Pediatric Orthopaedic Society of North America) web sites. The accessibility, usability, and reliability of online medical information in the "Children" section of the AAOS web site and on the POSNA web site were assessed with use of the LIDA tool. Flesch-Kincaid (FK) and Flesch Reading Ease (FRE) values were also calculated to assess the readability of the pediatric education material. Patient education materials on each web site scored in the moderate range in assessments of accessibility, usability, and reliability. FK and FRE values indicated that the readability of each web site remained at a somewhat higher (more difficult) level than the recommended benchmark. The quality and readability of online information for children on the AAOS and POSNA web sites are acceptable but can be improved further. The quality of online pediatric orthopaedic patient education materials may affect communication with patients and their caregivers, and further investigation and modification of quality are needed.

Full Text Available Machiavellianism is characterised by a manipulative interpersonal style, willingness to exploit others, and a preference for emotionally detached relationships. The present studies investigate the extent to which Machiavellianism influences relationship satisfaction and romantic relationship quality. In Study 1, 194 heterosexual partnered women completed Machiavellianism and Relationship Satisfaction measures. Women with higher levels of Machiavellianism reported lower levels of relationship satisfaction. In Study 2, 132 heterosexual partnered women completed Machiavellianism, Trust, Commitment, Control, and Emotional Abuse scales. Women with higher levels of Machiavellianism perceived their partners to be less dependable, reported less faith in their partners, and were less willing to persist with the relationship than those with low levels of Machiavellianism. With regards to negative behavior, Machiavellianism predicted each form of control and emotional abuse investigated, such that those with high levels of Machiavellianism were more likely to engage in controlling behavior and emotional abuse. Findings have important implications for the prediction of romantic relationship quality and in particular for negative behavior such as control and abuse.

On-line fashion communities in which participants post photos of personal fashion items for viewing and possible purchase by others are becoming increasingly popular. Generally, these photos are taken by individuals who have no training in photography with low-cost mobile phone cameras. It is desired that photos of the products have high aesthetic quality to improve the users' online shopping experience. In this work, we design features for aesthetic quality inference in the context of online fashion shopping. Psychophysical experiments are conducted to construct a database of the photos' aesthetic evaluation, specifically for photos from an online fashion shopping website. We then extract both generic low-level features and high-level image attributes to represent the aesthetic quality. Using a support vector machine framework, we train a predictor of the aesthetic quality rating based on the feature vector. Experimental results validate the efficacy of our approach. Metadata such as the product type are also used to further improve the result.

A concern by some is what happens to the quality of instruction in courses with high enrollments. The purpose of this research was to examine online class size and its relationship to, and potential influence on, an instructor’s performance. Results were mixed indicating that class size had a positive relationship with some the variables meant to measure online instructor performance and a negative relationship with others. Online class size was seen as having the most concerning relationship and potential influence on an instructor’s ability to provide quality feedback to students and for his/her expertise to be used consistently and effectively.
Full Text Available Tourism-dependent economy, unfavourable structure of accommodation and hotel capacity, seasonality of business and liquidity problems indicate importance of the relationships between hotels and banks in Croatia. Since the capital investments in new and modern capacities are necessity, the quality of their relationship would determine the future of Croatian economy as a whole in the long run. Regarding the capital investments, it is crucially important that cooperation between the employees in both business entities is based on the satisfaction, trust and commitment. In this way, every potential uncertainty as a consequence of the entity’s actions could be minimized. In this paper, 356 tourist objects are hierarchically clustered according to the relationship quality dimensions for the purpose of testing the characteristics according to which the clusters significantly differentiate. Consequently, the interdependence between the observed relationship quality dimensions is examined.

Assessing product-image quality is important in the context of online shopping. A high quality image that conveys more information about a product can boost the buyer's confidence and can get more attention. However, the notion of image quality for product-images is not the same as that in other domains. The perception of quality of product-images depends not only on various photographic quality features but also on various high level features such as clarity of the foreground or goodness of the background etc. In this paper, we define a notion of product-image quality based on various such features. We conduct a crowd-sourced experiment to collect user judgments on thousands of eBay's images. We formulate a multi-class classification problem for modeling image quality by classifying images into good, fair and poor quality based on the guided perceptual notions from the judges. We also conduct experiments with regression using average crowd-sourced human judgments as target. We compute a pseudo-regression score with expected average of predicted classes and also compute a score from the regression technique. We design many experiments with various sampling and voting schemes with crowd-sourced data and construct various experimental image quality models. Most of our models have reasonable accuracies (greater or equal to 70%) on test data set. We observe that our computed image quality score has a high (0.66) rank correlation with average votes from the crowd sourced human judgments.
The purpose of this study was to examine the qualities of support, relatedness, and negative interaction within parent-child and teacher-student relationships and their association with cognitive, psychological, and behavioral engagement. Additionally, this study explored the contributions of cognitive and psychological engagement on behavioral engagement. The role of gender, grade, and ethnicity on relationship quality and engagement was also considered. Participants (n=311) were students in grades three through five from a suburban school district in southeastern Michigan. Perceptions of teacher-student relationship quality varied by grade level. In general, younger students reported greater teacher support and relatedness in comparison to older students. Conversely, older students perceived greater conflict within the teacher-student relationship. Student engagement also varied by grade level, with younger students reporting greater engagement than older students. Ethnicity also contributed to variance in student engagement, with African American students reporting significantly more engagement than Caucasian or Multiracial students. Teacher-student relationship quality was a significant predictor of student engagement, even after controlling for student characteristics and parent-child relationship variables. Results of path analysis revealed that cognitive and psychological engagement contributed significantly to behavioral engagement.

Recent studies suggest that the online and offline behaviors young people display in romantic relationships are closely related. However, the differential effects of the dimensions of couple quality in the online context have not yet been explored in depth. The aim of this study was to explore online couple quality in young-adult relationships, and its association with romantic relationship satisfaction, also looking at effects of gender, age, and length of the relationship. 431 university students currently in a romantic relationship (68.2% females; mean age = 21.57) participated in this study. They completed different self-report measures to tap the online quality of their romantic relationships (online intimacy, control, jealousy, intrusiveness, cyberdating practices, and communication strategies) and level of satisfaction with those relationships. Results showed that participants more often reported online intimacy (M men = 2.49; M women = 2.38) than the negative scales of online quality (mean ranged from .43 to 1.50), and all the online quality scales decreased with age (correlations ranged from -.12 to -.30) and relationship length (correlations ranged from -.02 to -.20). Linear regression analyses indicated that online intimacy (b = .32, p = .001) and intrusiveness (b = .11, p = .035) were positively related to relationship satisfaction, while cyberdating practices (b = -.20, p = .001) and communication strategies (b = -.34, p = .001) were negatively correlated with relationship satisfaction. Moreover, gender and relationship length moderated some of these associations. Results indicate that while online quality and relationship satisfaction are related, the impact of different online quality dimensions on relationship satisfaction differs depending on a participant's sex, age, and relationship length.

Some researchers have illustrated how the Internet can provide users with an ideal atmosphere to explore sexuality; however, most have stressed the Internet's negative impact on intimate relationships. Notably, much of this research has focused on the small minority of men who compulsively engage in online sexual activities (OSA), overlooking the majority of men and women who use OSA recreationally (either individually or with a partner). Addressing these limitations, data on heterosexual adults in committed relationships were taken from the 2004 "ELLE/msnbc.com Cyber-sex and Romance Survey" (n = 8,376). In quantitative analyses, men were less likely than women to express concerns and more likely to hold favorable attitudes about their partner's OSA. With regard to the impact of OSA on intimate relationships, men and women did not differ in becoming "more open to new things," and finding it easier "to talk about what [they] want sexually." Negative impacts were also identified, with women more likely to indicate they had less sex as a result of a partner's OSA, and men more likely to indicate they were less aroused by real sex as a result of their own OSA. Generally, qualitative results mirrored quantitative ones. Additionally, qualitative data suggested that moderate or light amounts of OSA yield relationship benefits for both female and male users, including increases in the quality and frequency of sex, and increased intimacy with real partners. In addition, men who used the Internet moderately, and men and women who reported being light users, stated that engaging in tandem OSA fostered better sexual communication with partners. Findings underscore the need to explore further the impact that online sexual activities can have on real-life committed relationships.

Online relationships are increasingly central to many people's lives. As a result, there is a growing need to scientifically examine their psychosocial implications. This study developed and tested the Online Relationship Initiation Scale (ORIS) through classical and item response theory analyses to address this need. An anonymous online survey included 713 adults, aged 18-71 years. The ORIS was tested on psychometric properties and examined for associations with gender and several standardized psychosocial measures. Results demonstrated unidimensionality of nine items, strong factor loadings, and high internal consistency (α = 0.90, ωt = 0.94). All items captured significant information on the latent trait and none showed differential item functioning by sex, age group, or ethnicity. General linear modeling confirmed hypotheses that men were more likely than women to initiate online relationships. Online relationship initiation was not strongly associated with perceived social support, but was positively related to financial distress, and willingness to engage in infidelity or unprotected sex. The ORIS was negatively associated with age and satisfaction with life and showed modest interactions with ethnicity and hours online. This study provided empirical evidence for an interpersonal relationship initiation construct. The ORIS was shown to be a psychometrically sound instrument for evaluating online interpersonal behaviors and their associations with psychosocial and demographic factors. Such psychometrically sound instruments can be useful in exploring online interpersonal behaviors and their significance.

Full Text Available Franchise literature disputes how the relationship between franchisors and franchisees develops over time. Traditional lifecycle theory views relationships following an ascendant curve, in which relationship quality and performance strengthen over time. Another perspective better reflects the peculiarities of the franchisor-franchisee relationship, indicating that relationship quality in franchise systems follows a U-shaped curve. There is also limited research on the moderating effect of time on the relationship between relational variables and outcomes. This study sheds light on the influence of relationship duration on relationship quality and financial performance in the franchisee-franchisor relationship. Using a self-report survey from a sample of 342 franchisees, mean and regression analyses are conducted to test relationships. Results confirm the time effect on franchisor-franchisee relationship quality and performance, but the hypothesized shape of relationship phases is only partially confirmed. Moreover, time has a positive moderating effect on the impact of relationship quality on financial performance.

Full Text Available Background: A typology of desirable social conditions in supervisory relationships suggested that such conditions may also be desirable in other forms of labour relationships. A literature review confirmed that trust, compliance, fairness and good faith can be confidently regarded as universally desirable social conditions in all forms of individual or collective labour relationships between employers and employees. Aim: The purpose of this study was to determine if primary labour relationship quality (PLQ can be confidently conceptualised as a social construct that strongly relates to the perceived levels of compliance, fairness and good faith in supervisory or primary labour relationships. Setting: A combination of random and convenience sampling approaches was implemented to collect PLQ related data from 454 voluntary respondents, who were subordinate employees in the Tshwane region. Methods: A quantitative research methodology was adopted. This included conceptual definition of the PLQ construct, objective measurement of PLQ levels of voluntary respondents in an adequately sized sample, factor analysis and testing for relationships and differences in means between variables. Results: Data analysis results confirmed that it can be confidently concluded that the conceptual definition of PLQ was valid, and that positive PLQ perceptions of subordinate employees were significantly related to at least two other forms of desirable organisational outcomes. Conclusion: PLQ perceptions can be confidently defined as a distinct subjective quality estimate that is assimilated from unique expectations and perceptions of the levels of compliance, fairness, good faith and trust that a supervisor displays in a labour relationship with an immediate subordinate.

Background: The internet is a phenomena that changes human, specially the younger generation's, life in the 21st century. Online communication is a common way of interacting among adolescents who experience feelings of social anxiety. The aim of this study was to investigate the relationship between social anxiety and online communication in adolescents. Methods: Three hundred and thirty students aged 13-16 years were selected from eight middle and high schools in Isfahan by multistage cluster sampling. Each of them completed a survey on the amount of time they spent communicating online, the topics they discussed, the partners they engaged with and their purpose for communicating over the internet. They also completed the social anxiety scale of adolescents. Data were analyzed using Pearson correlation and multiple regression. Results: Results of the Pearson analysis showed that online communication has a significant positive relationship with apprehension and fear of negative evaluation (AFNE), and a significant negative relationship with tension and inhibition in social contact (TISC) (P online communication is AFNE, TISC. Conclusions: It is suggested that students from middle school get assessed in terms of the level of social anxiety. Then, the quality and quantity of their online communication should be moderated through group training and consulting and referral to medical centers, if needed. The results of this study may lead to optimal use of online communications and reduce the personal, social and psychological problems of adolescents. PMID:23671769

ABSTRACT Franchise literature disputes how the relationship between franchisors and franchisees develops over time. Traditional lifecycle theory views relationships following an ascendant curve, in which relationship quality and performance strengthen over time. Another perspective better reflects the peculiarities of the franchisor-franchisee relationship, indicating that relationship quality in franchise systems follows a U-shaped curve. There is also limited research on the moderating effe...

Previous studies found important associations between body image, sexual satisfaction, and perceived romantic relationship quality, but mainly focused on one individual's perceptions rather than both partners. To take the interdependency of romantic partners into account, the present study examined these associations in romantic couples with a dyadic approach. In a cross-sectional design, 151 Dutch heterosexual couples completed an online survey measuring body image, sexual satisfaction, and perceived relationship quality. Hypotheses were tested using the actor-partner interdependence model (APIM) and an APIM extended with a mediator (APIMeM), with couple members' body image as predictors, couple members' sexual satisfaction as mediators, and couple members' relationship quality as outcomes. Results indicated that within individuals, a more positive body image was linked to higher perceived romantic relationship quality through greater sexual satisfaction. No gender differences were found, implying that body image and sexual satisfaction are equally strongly associated with perceived relationship quality in women and men. Results revealed no associations of an individual's body image and sexual satisfaction with the partner's perceived relationship quality. These findings implicate that interventions focusing on developing and maintaining a positive body image may be helpful in building on a more satisfying sex life and higher perceived relationship quality.

Online social networking sites (SNSs) such as Facebook, Twitter, and MySpace are used by billions of people every day to communicate and interact with others. There has been increasing interest in the potential impact of online social networking on wellbeing, with a broadening body of new research into factors associated with both positive and negative mental health outcomes such as depression. This systematic review of empirical studies (n = 30) adds to existing research in this field by examining current quantitative studies focused on the relationship between online social networking and symptoms of depression. The academic databases PsycINFO, Web of Science, CINAHL, MEDLINE, and EMBASE were searched systematically using terms related to online social networking and depression. Reporting quality was critically appraised and the findings discussed with reference to their wider implications. The findings suggest that the relationship between online social networking and symptoms of depression may be complex and associated with multiple psychological, social, behavioral, and individual factors. Furthermore, the impact of online social networking on wellbeing may be both positive and negative, highlighting the need for future research to determine the impact of candidate mediators and moderators underlying these heterogeneous outcomes across evolving networks.
Full Text Available Online education programs in nursing are increasing rapidly. Faculty need to be competent in their role and possess the skills necessary to positively impact student outcomes. Existing research offers effective teaching strategies for online education; however, there may be some disconnect in the application of these strategies and faculty perceptions of associated outcomes. Focus groups were formed to uncover how nursing faculty in an online program define and describe teaching effectiveness and quality indicators in an asynchronous online environment. A semistructured interview format guided group discussion. Participants (n=11 included nurse educators from an online university with an average of 15 years of experience teaching in nursing academia and 6 years in an online environment. Teaching effectiveness, indicators of quality, and student success were three categories that emerged from the analysis of data. What materialized from the analysis was an overarching concept of a “dance” that occurs in the online environment. Effective online teachers facilitate, connect, lead, and work in synchrony with students to obtain indicators of quality such as student success, student improvement over time, and student application of knowledge to the professional role.

This study was designed to examine the qualities of online friendships with different gender compositions that had been maintained for varying periods of time. A total of 167 Hong Kong Internet-users rated the qualities of their same-sex and cross-sex online friendships on measures such as intimacy, trust, self-disclosure, and relational satisfaction. A 2 (gender of respondents: male vs. female) x 2 (gender of online friends: same-sex vs. opposite-sex) x 3 (duration of friendships: less than 1 year vs. 1-2 years vs. more than 2 years) factorial design was adopted. MANOVA results reveal the three-way interaction effect on intimacy, trust, and relational satisfaction. Specifically, the qualities of male-female, female-male, and female-female online friendships were generally higher for those with a longer duration than those at the early stage of friendship development. However, the qualities of male-male friendships that had been maintained for more than 2 years were lower than those maintained for 2 years or less. These findings suggest that qualities of online friendships are subject to effects of gender composition and duration. The conceptual implications of these results are discussed.

The goal of this study was to examine the effect of quality of workplace relationships on the mental health of employed undergraduates, with work-related variables as a potential mechanism. Participants were 170 employed students (76% female, average age = 19.9) recruited in March 2011. Most worked part-time and had been at their jobs over a year. Students were recruited from an undergraduate introductory psychology course and completed online surveys about the quality of workplace relationships, mental health (ie, somatic stress symptoms, depression, anxiety, and life satisfaction), and work-related variables (ie, job satisfaction, support, turnover and burnout). Students who reported having workplace relationships with co-occurring positivity and negativity had worse self-reported mental health outcomes than students reporting having wholly positive relationships. The relationship between workplace relationship quality and mental health was mediated by negative work-related variables. Workplace relationships-even in part-time employment settings-influence college students' mental health.

The volume of health-related user-created content, especially hospital-related questions and answers in online health communities, has rapidly increased. Patients and caregivers participate in online community activities to share their experiences, exchange information, and ask about recommended or discredited hospitals. However, there is little research on how to identify hospital service quality automatically from the online communities. In the past, in-depth analysis of hospitals has used random sampling surveys. However, such surveys are becoming impractical owing to the rapidly increasing volume of online data and the diverse analysis requirements of related stakeholders. As a solution for utilizing large-scale health-related information, we propose a novel approach to identify hospital service quality factors and overtime trends automatically from online health communities, especially hospital-related questions and answers. We defined social media-based key quality factors for hospitals. In addition, we developed text mining techniques to detect such factors that frequently occur in online health communities. After detecting these factors that represent qualitative aspects of hospitals, we applied a sentiment analysis to recognize the types of recommendations in messages posted within online health communities. Korea's two biggest online portals were used to test the effectiveness of detection of social media-based key quality factors for hospitals. To evaluate the proposed text mining techniques, we performed manual evaluations on the extraction and classification results, such as hospital name, service quality factors, and recommendation types using a random sample of messages (ie, 5.44% (9450/173,748) of the total messages). Service quality factor detection and hospital name extraction achieved average F1 scores of 91% and 78%, respectively. In terms of recommendation classification, performance (ie, precision) is 78% on average. Extraction and

Online university students are a growing population whose health has received minimal attention. The purpose of this cross-sectional Internet survey was to identify risk factors for the health status among online university students. This online survey collected data from 301 online university students through a large, US-based participant pool and LinkedIn. Health status was measured using 3 elements of health-related quality of life (HRQOL): self-rated overall health (SRH), unhealthy days, and recent activity limitation days. All 3 measures were dichotomized. The odds of poor SRH were higher for people who reported a body mass index in the overweight and obese categories (odds ratio [OR] = 2.99, P students who are low income, in disadvantaged racial groups, who are overweight, smoke, and who do not exercise. © The Author(s) 2014.
Full Text Available Increasing the visibility of a journal is the key to increasing quality. The International Network for the Availability of Scientific Publications works with journal editors in the global South to publish their journals online and to increase the efficiency of the peer review process. Editors are trained in using the Open Journals System software and in online journal management and strategy so they have the tools and knowledge needed to initiate a ‘virtuous cycle' in which visibility leads to an increase in the number and quality of submissions and in turn, increased citations and impact. In order to maximise this increase in quality, it must be supported by strong editorial office processes and management.

The aim of this study was to develop a method for online spectrofluorimetric quality control of naphazoline (NPZ) in pharmaceuticals and raw drugs. A combination of a flow-injection analysis (FIA) system with micellar-enhanced fluorescence detection is presented as a powerful alternative for the rapid and sensitive analysis of naphazoline. Since NPZ shows low native fluorescence, the use of an anionic surfactant, such as sodium dodecyl sulphate (SDS), provides a considerable enhancement of fluorescence intensity and the nature of the technique allows a possible and easy adaptation to a FIA system. Using λ(exc) = 280 nm and λ(em) = 326 nm, a good linear relationship (LOL) was obtained in the range 0.003-10 µg mL(-1) with a detection limit (LOD) of 3 × 10(-4) µg mL(-1) (s/n = 3). Parameters related to the nature of the analytical signal and to the FIA manifold were optimized. Satisfactory recoveries were obtained in the analysis of commercial pharmaceutical formulations. The proposed method is simple, accurate and allows for high-speed sampling and considerably shorter analysis times. In addition, it requires inexpensive equipment and reagents and has easy operational conditions and no side effects, thus avoiding environmental pollution through toxic waste.

The ubiquity of the Internet is changing the way people obtain their health information. Although there is an abundance of heart failure information online, the quality and health literacy demand of these information are still unknown. The purpose of this study is to evaluate the quality and health literacy demand (readability, understandability, and actionability) of the heart failure information found online. Google, Yahoo, Bing, Ask.com, and DuckDuckGo were searched for relevant heart failure Web sites. Two independent raters then assessed the quality and health literacy demand of the included Web sites. The quality of the heart failure information was assessed using the DISCERN instrument. Readability was assessed using 7 established readability tests. Finally, understandability and actionability were assessed using the Patient Education Materials Assessment Tool for Print Materials. A total of 46 Web sites were included in this analysis. The overall mean quality rating was 46.0 ± 8.9 and the mean readability score was 12.6 grade reading level. The overall mean understandability score was 56.3% ± 16.2%. Finally, the overall mean actionability score was 34.7% ± 28.7%. The heart failure information found online was of fair quality but required a relatively high health literacy level. Web content authors need to consider not just the quality but also the health literacy demand of the information found in their Web sites. This is especially important considering that low health literacy is likely prevalent among the usual audience.

在网络购物环境下，根据感知公平理论、认知评价理论、情感控制理论和后悔理论，本文提出了一个关系质量作为调节变量的服务补救情境下的“感知公平一情绪反应（后悔）一行为意向”的概念模型。采用情景模拟法，选取学生为调查对象，验证了感知公平三维度对在线消费者后悔有显著的负向影响，进而显著影响服务补救后的行为意向。但是，关系质量对后悔与行为意向的关系没有显著的调节作用。%Although there are some literatures which studied the relationships of the oit-hne service recovery, the consumer moods （positive or negative）, and the behavioral intentions, the few literatures analyze the relationship among the service recovery, online consumer regret and behavioral intentions in the network shopping. According to the justice theory, consumers tend to evaluate the process of service recovery from three-dimen- sion perception justice, namely distribution justice, procedure justice and interactive justice. According to cognitive evaluation theory and emotional control theory, the mood is the psychological reaction or psychological state＇s self- adjustment after evaluating a particular consumer experience（ such as the service recovery）, including positive and negative emotions. According to the regret theory, the regret is a special kind of negative emotion, and has an effec- tive influence on consumers＇ behavior intentions. According to the related literature of relationship quality, the rela- tionship quality has some strong regulation effects between attitude and behavior. Therefore, this paper puts forward a conceptual model, in which relationship quality moderates the relationship of ＂perception justice-emotional respon- ses（regret）-behavior intention＂ under service recovery situation. Scholars adopt generally the scenario simulation method for service failure and service recovery, so this paper

Online social networks, such as Facebook, have gained immense popularity and potentially affect the way people build and maintain interpersonal relationships. The present study sought to examine time spent on online social networks, as it relates to intimacy and relationship satisfaction experienced in romantic relationships. Results did not find relationships between an individual's usage of online social networks and his/her perception of relationship satisfaction and intimacy. However, the study found a negative relationship between intimacy and the perception of a romantic partner's use of online social networks. This finding may allude to an attributional bias in which individuals are more likely to perceive a partner's usage as negative compared to their own usage. Additionally, it was found that intimacy mediates the relationship between online social network usage and overall relationship satisfaction, which suggests that the level of intimacy experienced in a relationship may serve as a buffer that protects the overall level of satisfaction.

How to design an accurate algorithm for ranking the object quality and user reputation is of importance for online rating systems. In this paper we present an improved iterative algorithm for online ranking object quality and user reputation in terms of the user degree (IRUA), where the user's reputation is measured by his/her rating vector, the corresponding objects' quality vector and the user degree. The experimental results for the empirical networks show that the AUC values of the IRUA algorithm can reach 0.9065 and 0.8705 in Movielens and Netflix data sets, respectively, which is better than the results generated by the traditional iterative ranking methods. Meanwhile, the results for the synthetic networks indicate that user degree should be considered in real rating systems due to users' rating behaviors. Moreover, we find that enhancing or reducing the influences of the large-degree users could produce more accurate reputation ranking lists.

The purpose of this study was to examine whether attention-deficit/hyperactivity disorder (ADHD) symptom levels in college undergraduates are associated with poorer romantic relationship quality, and to test whether emotion regulation difficulties, perceived stress, and hostile relationship conflict mediate this association. The sample consisted of 189 undergraduate students aged 18 to 25. Self-report measures of ADHD symptoms, relationship quality, and the proposed mediators were collected via online survey from May through August 2011. Participants who reported clinically significant levels of both hyperactivity-impulsivity and inattentiveness (consistent with ADHD-C) had lower relationship quality than those whose self-reported symptoms indicated no ADHD diagnosis. Further, for women only, both hyperactive-impulsive and inattentive symptom levels were negatively associated with relationship quality. Emotion regulation problems and hostile relationship conflict mediated this association. Findings suggest that ADHD impairs relationship quality among young adults and suggest mechanisms through which this impairment might occur.

Technology-delivered interventions addressing a broad range of problems for which clients present for therapy are proliferating. However, little is known of leadership dynamics that emerge in online group interventions. The purpose of this study was to assess the types of leadership qualities that would emerge in an online social support group intervention to improve medication adherence for men with HIV, and to characterize the demographic and psychosocial profiles of leaders. Written posts ( n =616) from 66 men were coded using an adapted version of the Full Range Model of Leadership. Results showed that 10% ( n =64) of posts reflected one of five leadership types, the most common of which was mentoring/providing feedback (40% of leadership posts). The next most common leadership style were instances in which encouragement was offered (30% of leadership posts). Leaders appeared to have lived with HIV longer and have higher Internet knowledge scores than non-leaders. Results indicate that online group interventions potentially may be useful to supplement traditional face-to-face treatment by providing an additional venue for group members to mentor and provide emotional support to each other. However, additional research is needed to more fully understand leadership qualities and group dynamics in other online group intervention settings.

This review deals with the published literature to date while examining the relationship between online gambling, mental health problems, and substance use. Online gambling, particularly problematic gambling online, was found to be associated with poor mental health and use of various substances. Recent preliminary evidence also suggests that online gamblers may be at a greater risk of some substance use and mental health problems, relative to nononline gamblers. However, many of the reviewed studies were limited by investigation of online gambling behaviors only; these samples may have inadvertently comprised individuals who engage in both online and nononline gambling. Future research is required to address these limitations.

The Internet has become an important source of health-related information for consumers, among whom younger women constitute a notable group. The aims of this study were (1) to evaluate the quality and readability of online information about gynecologic cancer using validated instruments and (2) to relate the quality of information to its readability. Using the Alexa Rank, we obtained a list of 35 Web pages providing information about 7 gynecologic malignancies. These were assessed using the Health on the Net (HON) seal of approval, the Journal of the American Medical Association (JAMA) benchmarks, and the DISCERN instrument. Flesch readability score was calculated for sections related to symptoms and signs and treatment. Less than 30% of the Web pages displayed the HON seal or achieved all JAMA benchmarks. The majority of the treatment sections were of moderate to high quality according to the DISCERN. There was no significant relationship between the presence of the HON seal and readability. Web pages achieving all JAMA benchmarks were significantly more difficult to read and understand than Web pages that missed any of the JAMA benchmarks. Treatment-related content of moderate to high quality as assessed by the DISCERN had a significantly better readability score than the low-quality content. The online information about gynecologic cancer provided by the most frequently visited Web pages is of variable quality and in general difficult to read and understand. The relationship between the quality and readability remains unclear. Health care providers should direct their patients to reliable material online because patients consider the Internet as an important source of information.

Online transportation service is known for its accessibility, transparency, and tariff affordability. These points make online transportation have advantages over the existing conventional transportation service. Online transportation service is an example of disruptive technology that change the relationship between customers and companies. In Indonesia, there are high competition among online transportation provider, hence the companies must maintain and monitor their service level. To understand their position, we apply both sentiment analysis and multiclass classification to understand customer opinions. From negative sentiments, we can identify problems and establish problem-solving priorities. As a case study, we use the most popular online transportation provider in Indonesia: Gojek and Grab. Since many customers are actively give compliment and complain about company’s service level on Twitter, therefore we collect 61,721 tweets in Bahasa during one month observations. We apply Naive Bayes and Support Vector Machine methods to see which model perform best for our data. The result reveal Gojek has better service quality with 19.76% positive and 80.23% negative sentiments than Grab with 9.2% positive and 90.8% negative. The Gojek highest problem-solving priority is regarding application problems, while Grab is about unusable promos. The overall result shows general problems of both case study are related to accessibility dimension which indicate lack of capability to provide good digital access to the end users.

Full Text Available The purpose of this study was to investigate how Facebook use is leading to negative relationship outcomes such as cheating and breakup by assessing users’ perceived relationship qualities. It was hypothesized that Facebook-related conflict will be negatively related with users’ relationship length and will also be negatively related with their perceived relationship satisfaction, commitment, and love. Facebook-related conflict further mediates the relationship between relationship length and perceived relationship satisfaction, commitment, and love. Self-report data were gathered from participants (N = 101 in an online survey by employing standard questionnaires. A set of regression and mediation analyses confirmed all the hypotheses of the study. That is, Facebook-related conflict mediates the relationship between relationship length and perceived relationship satisfaction, commitment, and love. Moreover, the magnitude of mediation was highest for relationship satisfaction. Implications for future research and contributions are discussed.

Full Text Available This study set out to investigate what role the quality of the relationship between business leaders and their employees played in the performance of their business. The study compared the business performance of forty-five area managers in one of the major listed banks in South Africa with their specific leader/employee relationship profiles. The research approach was quantitative and of a correlational nature. The results indicate that although certain elements within the relationship between business leaders and employees indeed have an influence on business performance this alone was not a sufficient condition. The study suggested that the dimensions relating to vision, trust, accountability and decision- making have the strongest influence on business performance. Further research in this area is suggested.

The consumption of fresh-cut agricultural produce in Korea has been growing. The browning of fresh-cut vegetables that occurs during storage and foreign substances such as worms and slugs are some of the main causes of consumers' concerns with respect to safety and hygiene. The purpose of this study is to develop an on-line system for evaluating quality of agricultural products using hyperspectral imaging technology. The online evaluation system with single visible-near infrared hyperspectral camera in the range of 400 nm to 1000 nm that can assess quality of both surfaces of agricultural products such as fresh-cut lettuce was designed. Algorithms to detect browning surface were developed for this system. The optimal wavebands for discriminating between browning and sound lettuce as well as between browning lettuce and the conveyor belt were investigated using the correlation analysis and the one-way analysis of variance method. The imaging algorithms to discriminate the browning lettuces were developed using the optimal wavebands. The ratio image (RI) algorithm of the 533 nm and 697 nm images (RI533/697) for abaxial surface lettuce and the ratio image algorithm (RI533/697) and subtraction image (SI) algorithm (SI538-697) for adaxial surface lettuce had the highest classification accuracies. The classification accuracy of browning and sound lettuce was 100.0% and above 96.0%, respectively, for the both surfaces. The overall results show that the online hyperspectral imaging system could potentially be used to assess quality of agricultural products.

Full Text Available Purpose - An official destination website (ODW is a key component for tourist’s decision-making processes. ODW acts as a direct channel where users may share experiences and opinions about previous or future travels. At the same time, it drives user participation in destination branding activities. In this context, it is crucial to identify how the destination website, using Web 2.0 technologies, could motivate user’s participation with the brand. The purpose of this paper is to propose and evaluate a model that posits the destination website quality as a determinant factor to predict users’ attitudes toward the website and their willingness to participate in co-creation experiences. Design/methodology/approach - Using a combined qualitative and quantitative method, this paper provides an exploratory research that examines the role of destination website quality on attitudes toward the website and the willingness to participate in online co-creation experiences. Findings - Findings confirm that there is a direct and significant relationship between website quality, attitudes toward the website and willingness to participate in online co-creation experiences. Moreover, attitudes toward the website partially mediate relationships between destination website quality and willingness to participate in online co-creation experiences. Originality/value - The literature of value co-creation is trying to identify which factors drive consumer’s participation with brands across different consumption contexts. This study provides evidence that confirms, from a tourism destination website point of view, that website quality is one of these key factors that motives user’s co-creation with a destination.

Couples are increasingly utilizing newly developed online adaptations of couple therapy; however, different presenting problems could drive couples to seek either online or in-person services. This study compared the presenting problems of 151 couples seeking an online couple intervention for relationship distress (OurRelationship) with responses from 147 couples seeking in-person couple therapy. Presenting problems were generally consistent across gender and whether or not the respondent was the initial help-seeker. Online and in-person samples frequently endorsed difficulties with communication and emotional intimacy; however, they differentially endorsed trust, time together, and child/parenting difficulties. Therefore, while basing online interventions on existing couple therapies is generally supported, efforts should be made to tailor online services to meet the unique needs of this population. © 2018 American Association for Marriage and Family Therapy.

This study aimed to explore the relationship between online game addiction and aggression, self-control, and narcissistic personality traits, which are known as the psychological characteristics linked to "at-risk" populations for online game addiction. A total of 1471 online game users (males 82.7%, females 17.3%, mean age 21.30+/-4.96) participated in this study and were asked to complete several self-report measures using an online response method. Questionnaires included demographic information and game use-related characteristics of the samples, the online game addiction scale (modified from Young's Internet addiction scale), the Buss-Perry aggression questionnaire, a self-control scale, and the narcissistic personality disorder scale. Our results indicated that aggression and narcissistic personality traits are positively correlated with online game addiction, whereas self-control is negatively correlated with online game addiction (ponline game addiction could be predicted based on the person's narcissistic personality traits, aggression, self-control, interpersonal relationship, and occupation. However, only 20% of the variance in behavioral consequences was explained with the model. An interesting profile has emerged from the results of this study, suggesting that certain psychological characteristics such as aggression, self-control, and narcissistic personality traits may predispose some individuals to become addicted to online games. This result will deepen our understanding of the "at-risk" population for online game addiction and provide basic information that can contribute to developing a prevention program for people who are addicted to online games.

The aim of this research was to investigate specific determinants or factors that influence consumer online trust in the B2C e-commerce with a focus on consumers. Constructs such as perceived security, perceived privacy, perceived third party assurance, perceived reputation, perceived familiarity and perceived website quality and their relationship with online trust in the B2C context were studied. In conducting the research, a convenience sampling technique was adopted in carrying out the survey. Questionnaires were distributed to the target respondents and the data were analyzed using SPSS version 24. A Pearson's correlation was used to test the six hypotheses identified in this study. The results provided evidence that perceived security has the greatest influence on online trust. This was followed closely by perceived reputation and finally perceived privacy. This clearly shows that e-commerce consumer population considers these factors very imperative in engendering their trust in the virtual B2C e-commerce environment.

This study aimed to evaluate the relationship among dental students' attendance at class lectures, use of online lecture materials, and performance in didactic courses. The study was conducted with second-year predoctoral students at Tufts University School of Dental Medicine during the fall semester of 2014. Three basic science and three preclinical dental courses were selected for evaluation. Online usage for each participant was collected, and a survey with questions about attendance and online behavior was conducted. The final grade for each participant in each selected course was obtained and matched with his or her online usage and attendance. Out of a total 190 students, 146 (77%) participated. The results showed no significant relationship between students' grades and their class attendance or online usage except for a weak negative relationship between class attendance and online usage for the Epidemiology course (pattendance, online usage, and course grades, most of the students reported that having the online resources in addition to the lectures was helpful.

Background and aims Online gambling participation is increasing rapidly, with relatively little research about the possible effects of different gambling activities on problem gambling behaviour. The aim of this exploratory study was to examine the participation in online gambling activities and the relationship with problem gambling among an international sample of online gamblers. Methods An online gambling survey was posted on 32 international gambling websites and resulted in 1,119 respondents over a four-month period. Results Poker was the most popular gambling activity online. A number of online activities were associated with problem gambling, including: roulette, poker, horse race betting, sports betting, spread betting and fruit (slot) machines. Not surprisingly, those that gambled on these activities regularly (except poker) were more likely to be a problem gambler, however, what is interesting is that the reverse is true for poker players; those that gambled regularly on poker were less likely to be a problem gambler compared to the non-regular poker players. The majority of the players also gambled offline, but there was no relationship between problem gambling and whether or not a person also gambled offline. Discussion Problem gambling is associated more with certain online gambling activities than others, and those gambling on two or more activities online were more likely to be a problem gambler. Conclusion This paper can help explain the impact different online gambling activities may have on gambling behaviour. Consideration needs to be given to the gambling activity when developing and implementing treatment programmes.

The LHCb experiment at the LHC (CERN) has been optimised for high precision measurements of the beauty quark sector. Its main objective is to precisely determine and over-constrain the parameters of the CKM mixing matrix, and to search for further sources of CP violation and new physics beyond the Standard Model in rare B-decays. Efficient particle identification at high purities over a wide momentum range from around 1 to ~100GeV/c is vital to many LHCb analyses. Central to the LHCb particle identification strategy are two Ring Imaging CHerenkov (RICH) detectors which use Silica Aerogel and C4F10 and CF4 gas radiators. A rigorous quality control scheme is being developed to insure that the data recorded by the RICH detector meets the stringent requirements of the physics analyses. The talk summarises the LHCb RICH online monitoring and data-quality strategy. Multiple dedicated algorithms are deployed to detect any potential issue already during data-taking ranging from integrity checks, mis-alignments to cha...

Full Text Available In this study, two researchers explored student learning preferences in online courses. They used the scholarship of teaching and learning process as a research model, and embedded a web-based survey and online focus groups in the online courses they were teaching. After collecting data, the researchers conducted multiple logistic regression analyses to test their hypothesis that a relationship existed between some student factors and student preferences for types of online learning activities. The results of the data analysis revealed a statistically significant relationship between student age and student preference for certain types of online learning activities. Older students in the study indicated a much stronger preference for videos of the professor lecturing, while younger students tended to prefer more interactive learning strategies. Focus group comments from the older students provide insights into some of the reasons why they found watching video lectures to be helpful for their learning, and comments from younger students illustrate how they learn best in online courses. The researchers offer suggestions for online instructors based on the findings of this study, and they explain why online instructors may find the scholarship of teaching and learning research process especially helpful for both teaching and research efforts.

The purpose of this study was to understand the perceptions of teaching nursing students in online environments as experienced by nursing educators who have been teaching online for a minimum of 2 years. The study used an interview-based qualitative descriptive design. Semistructured interviews with 10 full-time nurse educators were conducted. The participants represented a range of ranks and teaching experience. Analysis involved a constant comparative process of initial and focused coding. Relationships were important to these nurse educators, and there was an interconnected nature among (a) student engagement and learning, (b) "knowing students," and (c) helping students meet their needs. Although different in how they experienced these elements, they seemed to share a sense that you have to know your students to help them meet their needs, and that you have to help them meet their needs so that they can learn, and building relationships within the online environment is key to all if this. Relationships are the heart of nursing and, for these nurse educators, a key aspect of nursing education. Having a strong relationship between nurse educators and nursing students supports student engagement in learning online. With continually increasing online nurse education, understanding these relationships is important to improve nursing education and consequently improve nursing practice.

Health care service is a high-credence service and patients may face difficulties ascertaining service quality in order to make choices about their available treatment options. Online health communities (OHCs) provide a convenient channel for patients to search for physicians' information, such as Word-of-Mouth (WOM), particularly on physicians' service quality evaluated by other patients. Existing studies from other service domains have proved that WOM impacts consumer choice. However, how patients make a choice based on physicians' WOM has not been studied, particularly with reference to different patient characteristics and by using real data. One thousand eight hundred fifty three physicians' real data were collected from a Chinese online health community. The data were analyzed using ordinary least squares (OLS) method. The study found that functional quality negatively moderated the relationship between technical quality and patient choice, and disease risk moderated the relationship between physicians' service quality and patient choice. Our study recommends that hospital managers need to consider the roles of both technical quality and functional quality seriously. Physicians should improve their medical skills and bedside manners based on the severity and type of disease to provide better service.

Conclusions: It is suggested that students from middle school get assessed in terms of the level of social anxiety. Then, the quality and quantity of their online communication should be moderated through group training and consulting and referral to medical centers, if needed. The results of this study may lead to optimal use of online communications and reduce the personal, social and psychological problems of adolescents.

Dealing with a cancer diagnosis and cancer treatment involves communication among clinicians, patients, families, friends and others affected by the illness. The hypothesis of this research is that an informatics system can effectively support the communication needs of cancer patients and their informal caregivers. Two design frameworks for online cancer communication are defined and compared. One is centered primarily on the users' interpersonal relationships, and the other is centered on the clinical data and cancer information. Five types of clinical and supportive relationships were identified and supported by in-depth interviews with cancer patients and their informal caregivers. Focusing the design of an online cancer communication system around the interpersonal relationships of patients and families may be an important step towards designing more effective paradigms for online cancer care and support.
Full Text Available Social neuroscience studies the neurobiological underpinnings of people making sense of people. Due to both conceptual and methodological constraints, the majority of studies in this field of research, however, has employed experimental paradigms that focus on social cognition from an observer's rather than from an interactor's point of view (offline vs. online social cognition. This calls for an increased effort to systematically investigate the neural bases of participation in real-time social interaction. In light of the ontogenetic primacy of social interaction over observation and the idea that neural networks established during social interaction may be ‘re-used’ during observation, other important objectives of the field will be to relate new findings into the neural bases of social interaction to previous work investigating the neural bases of social observation as well as to find ways to directly compare the two.

Prior research (Blackhart et al., 2014) found that rejection-sensitive individuals are more likely to use online dating sites. The purpose of the current research was to explain the relationship between rejection sensitivity and online dating site usage. Study 1 examined whether true self mediated the relation between rejection sensitivity and online dating. Study 2 sought to replicate the findings of Study 1 and to examine whether self-disclosure moderated the relationship between true self and online dating in the mediation model. Results replicated those found by Blackhart et al. and also found that true self mediated the relationship between rejection sensitivity and online dating site usage. These findings suggest that rejection-sensitive individuals feel they can more easily represent their "true" selves in online environments, such as online dating sites, which partially explains why they are more likely to engage in online dating.

Utilizing data from an eHarmony.com relationship questionnaire completed by new users (N = 5,434), this study identifies prioritized goals in new romantic relationships and whether importance of these goals differs by participants' age and gender. Overall, users valued interpersonal communication more than sex appeal. Older users rated sexual attraction as slightly less important than younger users did, but they still highly valued the goal. Women placed even greater emphasis on communication over sexual attraction compared to men. However, although men valued sexual attraction more than women at all ages, only the youngest women valued interpersonal communication more than young men. (c) 2015 APA, all rights reserved).

Full Text Available Relationship marketing has become extremely important recently due to the fierce competition in today's marketplace. Companies are required to build long-term profitable relationship with customers and to achieve customer loyalty. Also, switching behaviors frequently occur among most of targeted customers. Fewer studies, however, discuss the effects of relationship quality efforts on customer loyalty. Therefore, this study is aimed to investigate the impact of relationship quality on customer loyalty in B2B context in the Egyptian shipping services sector. Building on prior research, we propose relationship quality as a higher construct comprising trust, commitment and satisfaction. An analytical model is developed as a guideline to test the relationships between relationship quality dimensions and customer loyalty.

This study examined the relationship between parental and adolescent eHealth literacy and its impact on online health information seeking. Data were obtained from 1,869 junior high school students and 1,365 parents in Taiwan in 2013. Multivariate analysis results showed that higher levels of parental Internet skill and eHealth literacy were associated with an increase in parental online health information seeking. Parental eHealth literacy, parental active use Internet mediation, adolescent Internet literacy, and health information literacy were all related to adolescent eHealth literacy. Similarly, adolescent Internet/health information literacy, eHealth literacy, and parental active use Internet mediation, and parental online health information seeking were associated with an increase in adolescent online health information seeking. The incorporation of eHealth literacy courses into parenting programs and school education curricula is crucial to promote the eHealth literacy of parents and adolescents.

Children and adolescents now communicate online to form and/or maintain relationships with friends, family, and strangers. Relationships in "real life" are important for children's and adolescents' psychosocial development; however, they can be difficult for those who experience feelings of loneliness and/or social anxiety. The aim of this study was to investigate differences in usage of online communication patterns between children and adolescents with and without self-reported loneliness and social anxiety. Six hundred twenty-six students ages 10 to 16 years completed a survey on the amount of time they spent communicating online, the topics they discussed, the partners they engaged with, and their purposes for communicating over the Internet. Participants were administered a shortened version of the UCLA Loneliness Scale and an abbreviated subscale of the Social Anxiety Scale for Adolescents (SAS-A). Additionally, age and gender differences in usage of the online communication patterns were examined across the entire sample. Findings revealed that children and adolescents who self-reported being lonely communicated online significantly more frequently about personal and intimate topics than did those who did not self-report being lonely. The former were motivated to use online communication significantly more frequently to compensate for their weaker social skills to meet new people. Results suggest that Internet usage allows them to fulfill critical needs of social interactions, self-disclosure, and identity exploration. Future research, however, should explore whether or not the benefits derived from online communication may also facilitate lonely children's and adolescents' offline social relationships.

While research in the area of e-mental health has received considerable attention over the last decade, there are still many areas that have not been addressed. One such area is the comorbidity of psychological disorders in a Web-based sample using online assessment and diagnostic tools, and the relationships between comorbidities and psychosocial variables. We aimed to identify comorbidities of psychological disorders of an online sample using an online diagnostic tool. Based on diagnoses made by an automated online assessment and diagnostic system administered to a large group of online participants, multiple comorbidities (co-occurrences) of 21 psychological disorders for males and females were identified. We examined the relationships between dyadic comorbidities of anxiety and depressive disorders and the psychosocial variables sex, age, suicidal ideation, social support, and quality of life. An online complex algorithm based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision, was used to assign primary and secondary diagnoses of 21 psychological disorders to 12,665 online participants. The frequency of co-occurrences of psychological disorders for males and females were calculated for all disorders. A series of hierarchical loglinear analyses were performed to examine the relationships between the dyadic comorbidities of depression and various anxiety disorders and the variables suicidal ideation, social support, quality of life, sex, and age. A 21-by-21 frequency of co-occurrences of psychological disorders matrix revealed the presence of multiple significant dyadic comorbidities for males and females. Also, for those with some of the dyadic depression and the anxiety disorders, the odds for having suicidal ideation, reporting inadequate social support, and poorer quality of life increased for those with two-disorder comorbidity than for those with only one of the same two disorders.

Hospitals frequently evaluate their service quality based on the care and services provided to patients by their clinical and non-clinical staff.(1,2) However, such evaluations do not take into consideration the many interactions that patients have in online patient communities with the health-care organization (HCO) as well as with peer patients. Patients' interactions in these online communities could impact their perceptions regarding the HCO's service quality. The objective of this pilot study was to evaluate the impact of social support and responsiveness that patients experience in an HCO's online community on patients' perceptions regarding the HCO's service quality. The study data are collected from CHESS, a health-care programme (Comprehensive Health Enhancement Support System) run by the Centre for Health Enhancement System Studies at the University of Wisconsin-Madison. Findings show that the social support and the responsiveness received from peer patients in the online patient communities will impact patients' perceptions regarding the service quality of the HCO even when the organizational members themselves do not participate in the online discussions. The results indicate that interactions in such HCO-provided online patient communities should not be ignored as they could translate into patients' perceptions regarding HCOs' service quality. Ways to improve responsiveness and social support in an HCO's online patient community are discussed. © 2014 John Wiley & Sons Ltd.

Men with prostate cancer often need social support to help them cope with illness-related physiological and psychosocial challenges. Whether those needs are met depends on receiving support optimally matched to their needs. This study examined relationships between perceived stress, prostate cancer-related stigma, weak-tie support preference, and online community use for social support in a survey of online prostate cancer community participants (n = 149). Findings revealed a positive relationship between stigma and perceived stress. This relationship, however, was moderated by weak-tie support preference and online community use for social support. Specifically, stigma was positively related to perceived stress when weak-tie support was preferred. Analyses also showed a positive relationship between stigma and perceived stress in those who used their online community for advice or emotional support. Health communication scholars should work collaboratively with diagnosed men, clinicians, and online community administrators to develop online interventions that optimally match social support needs.

Relationships with parents and friends are important contexts for developing romantic relationship skills. Parents and friends may influence both the timing of involvement and the quality of romantic relationships. Three models of the joint influence of parents and friends (direct effects model, mediation model, and moderator model) have been proposed. The present study uses data from a longitudinal study (n = 1012; 49.8% female; 81.1% Caucasian) to examine how attachment and friendship quality at age 10 years predict romantic relationship involvement and quality at ages 12 and 15 years. The results supported the direct effects model, with attachment and friendship quality uniquely predicting different romantic relationship outcomes. The findings provide further support for the important influence of family and friends on early romantic relationships.

This study investigates how social support and family relationship perceptions influence breast cancer patients' online communication networks in a computer-mediated social support (CMSS) group. To examine social interactions in the CMSS group, we identified two types of online social networks: open and targeted communication networks. The open communication network reflects group communication behaviors (i.e., one-to-many or "broadcast" communication) in which the intended audience is not specified; in contrast, the targeted communication network reflects interpersonal discourses (i.e., one-to-one or directed communication) in which the audience for the message is specified. The communication networks were constructed by tracking CMSS group usage data of 237 breast cancer patients who participated in one of two National Cancer Institute-funded randomized clinical trials. Eligible subjects were within 2 months of a diagnosis of primary breast cancer or recurrence at the time of recruitment. Findings reveal that breast cancer patients who perceived less availability of offline social support had a larger social network size in the open communication network. In contrast, those who perceived less family cohesion had a larger targeted communication network in the CMSS group, meaning they were inclined to use the CMSS group for developing interpersonal relationships.

Full Text Available In face of a competitive virtual market, driven by the growth of online shopping and the increase in the number of retailers in this modality, measurements to evaluate the quality of online service become important, particularly due to the identification of a positive relationship between service quality and service performance. In this sense, Ding et al. (2011 proposed a consistent measure of the perceived quality of service in electronic commerce from the perspective of self-service: the e-SELFQUAL. This paper presents results of the replication of e-SELFQUAL in the Brazilian context. Two data collections were carried out: first, for a final sample of 106 students, there was an inadequacy in a construct of the scale, and a new translation was proposed. A second collection was applied to a sample of 175 people. The results confirmed the reliability and validity (convergent and discriminant of the scale, keeping the original items of the instrument. The findings indicate possible use of the e-SELFQUAL to measure the quality of online self-service in Brazil.
Full Text Available This study aimed to examine the relationship between certain factors of online learning readiness and learners’ end-of-course achievements. The study was conducted at a two-year post-secondary Turkish military school within the scope of the course titled Computer Literacy, which was designed and implemented in a blended way. The data were collected from 155 post-secondary military students through an online questionnaire. Three sub-scales of Hung et al.’s Online Learning Readiness Scale were used to collect the data during the first two weeks of the course. Descriptive and inferential statistics, such as Pearson correlation coefficients and linear regression analyses were performed to analyze the data. The descriptive results of the study indicated that students’ motivation for online learning was higher than both their computer/Internet self-efficacy and their orientations to self-directed learning. The inferential results revealed that the students’ end-of-course grades had significantly positive relationships with their computer/Internet self-efficacy and self-directed learning orientations. Finally, the students’ self-direction towards online learning appeared to be the strongest predictor of their achievements within the course; whereas computer/Internet self-efficacy and motivation for learning did not predict the learner achievement significantly.
Full Text Available Searching through online review sites becomes an alternative for consumers to obtain product information. The efficiency and effectiveness in finding quality information on the online review sites contributes to the popularity of online review sites among consumers at the moment. There are some previous studies discussing consumer trust on hotels being reviewed on online review sites, but the roles of information quality, homophily, and consumer risk propensity as antecedents of trust and online purchase intention are still questionable. The purpose of this study is to investigate how information quality, homophily, and consumer risk propensity affect consumer trust on hotels being reviewed on online review sites and on intention to make a reservation. A survey involving 430 young travelers from 16 countries was conducted in popular tourist destination. Results confirm that information quality influences consumers’ trust on hotel being reviewed and intention to make reservation. Moreover, consumer online trust is also found to affect intention to make reservation.

Internet gaming disorder (IGD) is the most recent term used to describe problematic or pathological involvement with computer or video games. This study examined whether this disorder is more likely to involve pathological involvement with online (i.e., Internet) games as opposed to offline games. We also explored the addictive potential of nine video game genres by examining the relationship between IGD and 2,720 games played by a sample of 13- to 40-year olds (N = 2,442). Although time spent playing both online and offline games was related to IGD, online games showed much stronger correlations. This tendency is also reflected within various genres. Disordered gamers spent more than four times as much time playing online role-playing games than nondisordered gamers and more than thrice as much time playing online shooters, whereas no significant differences for offline games from these genres were found. Results are discussed within the frame of social interaction and competition provided by online games.

The quality of teachers' relationships with children is a key predictor of children's later social emotional competence and academic achievement. Interventions to increase mindfulness among teachers have focused primarily on the impacts on teachers' subjective well-being, but not on the quality of their relationships with children. Furthermore, none of these interventions have involved preschool teachers. To consider the potential of mindfulness-based interventions to improve the quality of teachers' relationships with preschool-aged children, we examined data from an online survey of 1001 classroom teachers in 37 Pennsylvania Head Start Programs. Using path analysis we investigated the association between teachers' dispositional mindfulness and the quality of their relationships with children (conflict and closeness). We further examined whether this association was mediated by teacher depressive symptoms and moderated by perceived workplace stress. Higher levels of dispositional mindfulness among teachers were associated with higher quality relationships with children (less conflict and greater closeness). The association between greater dispositional mindfulness and less conflict was partially mediated by lower depressive symptoms, and the conditional direct effect of mindfulness on conflict was stronger when perceived workplace stress was lower. These findings suggest that preschool teachers who have higher levels of dispositional mindfulness may experience higher quality relationships with children in their classrooms. Interventions to increase levels of dispositional mindfulness among early childhood educators may improve their well-being along with the quality of their relationships with children, potentially impacting children's educational outcomes. The potential impacts of such interventions may be even stronger if structural and systemic changes are also made to reduce workplace stress.

Abstract. Existing work on the effects of social network sites (SNS) on well-being has often stressed that SNS can help people gain social support from their online networks, which positively affects their well-being. However, the majority of studies in this area have been cross-sectional in nature and/or relied on student samples. Using data from six waves of a longitudinal study with a representative sample of Dutch Internet users, we first examined whether users and nonusers of SNS differ in online social support and well-being (as indicated by life satisfaction and stress). In a second step, we investigated in more detail how SNS use – more specifically, asking for advice and the number of strong ties on these SNS – are related to online social support, stress, and satisfaction with life. Overall, our results provide no evidence for SNS use and online social support affecting either stress or life satisfaction. SNS users reported more online social support than nonusers did, but also higher levels of stress; the two groups did not differ in overall life satisfaction. With regard to the underlying processes, we found positive cross-sectional and longitudinal relationships between asking for advice on SNS and online social support, indicating that SNS can be an effective tool for receiving social support. However, online social support was not related to higher life satisfaction or reduced stress 6 months later; instead, it seems that SNS users with lower life satisfaction and/or higher stress seek more social support online by asking for advice on SNS.

We use the gender relations perspective from feminist theorizing to investigate how gender and daily emotion work predict daily relationship quality in 74 couples (148 individuals in dating, cohabiting, or married relationships) primarily from the southwest U.S. Emotion work is characterized by activities that enhance others’ emotional well-being. We examined emotion work two ways: trait (individuals’ average levels) and state (individuals’ daily fluctuations). We examined actor and partner effects of emotion work and tested for gender differences. As outcome variables, we included six types of daily relationship quality: love, commitment, satisfaction, closeness, ambivalence, and conflict. This approach allowed us to predict three aspects of relationship quality: average levels, daily fluctuations, and volatility (overall daily variability across a week). Three patterns emerged. First, emotion work predicted relationship quality in this diverse set of couples. Second, gender differences were minimal for fixed effects: Trait and state emotion work predicted higher average scores on, and positive daily increases in, individuals’ own positive relationship quality and lower average ambivalence. Third, gender differences were more robust for volatility: For partner effects, having a partner who reported higher average emotion work predicted lower volatility in love, satisfaction, and closeness for women versus greater volatility in love and commitment for men. Neither gender nor emotion work predicted average levels, daily fluctuations, or volatility in conflict. We discuss implications and future directions pertaining to the unique role of gender in understanding the associations between daily emotion work and volatility in daily relationship quality for relational partners.

The Unified Medical Language System (UMLS) contains many important ontologies in which terms are connected by semantic relations. For many studies on the relationships between biomedical concepts, the use of transitively associated information from ontologies and the UMLS has been shown to be effective. Although there are a few tools and methods available for extracting transitive relationships from the UMLS, they usually have major restrictions on the length of transitive relations or on the number of data sources. Our goal was to design an efficient online platform that enables efficient studies on the conceptual relationships between any medical terms. To overcome the restrictions of available methods and to facilitate studies on the conceptual relationships between medical terms, we developed a Web platform, onGrid, that supports efficient transitive queries and conceptual relationship studies using the UMLS. This framework uses the latest technique in converting natural language queries into UMLS concepts, performs efficient transitive queries, and visualizes the result paths. It also dynamically builds a relationship matrix for two sets of input biomedical terms. We are thus able to perform effective studies on conceptual relationships between medical terms based on their relationship matrix. The advantage of onGrid is that it can be applied to study any two sets of biomedical concept relations and the relations within one set of biomedical concepts. We use onGrid to study the disease-disease relationships in the Online Mendelian Inheritance in Man (OMIM). By crossvalidating our results with an external database, the Comparative Toxicogenomics Database (CTD), we demonstrated that onGrid is effective for the study of conceptual relationships between medical terms. onGrid is an efficient tool for querying the UMLS for transitive relations, studying the relationship between medical terms, and generating hypotheses.

Theoretically, nursing homes should engage in advertising for the following two reasons: (a) to improve awareness of the services offered in a particular market and (b) to signal high-quality services. In this study, we build upon results from prior studies of nursing home advertising activity, market competition, and quality. The purpose of this study was to examine the association between advertising expenses, price, and quality. We focused on answering the question: Do nursing homes use advertising and price to signal superior quality? The Texas Nursing Facilities Medicaid Cost Report, the Texas Quality Reporting System, and the Area Resource File were merged for the year 2003. We used three alternative measures of quality to improve the robustness of this exploratory analysis. Quality measures were examined using Bonferroni correlation coefficient analysis. Associations between advertising expenses and quality were evaluated using three regression models predicting quality. We also examined the association of the price of a private bed per day with quality. Advertising expenses were not associated with better nursing home quality as measured by three quality scales. The average price customers pay for one private bed per day was associated with better quality only in one of the three quality regression models. The price of nursing home care might be a better indicator of quality and necessary to increase as quality of care is improved in the nursing homes sector. Because more advertising expenditures are not necessarily associated with better quality, consumers could be mislead by advertisements and choose poor quality nursing homes. Nursing home administrators should focus on customer relationship management tools instead of expensive advertising. Relationship management tools are proven marketing techniques for the health services sector, usually less expensive than advertising, and help with staff retention and quality outcomes.

Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face-to-face teaching in gross anatomy courses. While face-to-face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second-year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500). A structural equation model was used to evaluate the relationship of prior student ability (represented by grade in prerequisite anatomy course) and final course grade and whether the relationship was mediated by program, campus or engagement with the online elements of the learning management system (LMS; proportion of documents and video segments viewed and number of interactions with discussion forums). PT students obtained higher grades and were more likely to engage with online course materials than EP and ES students. Prerequisite grade made a direct contribution to course final grade (P learning outcomes in a blended anatomy course can be predicted the by level of engagement with online content.

Online shopping has already become the new mode that a lot of customers try to adopt. At the same time, the online shopping could not be successfully completed without logistics service. Logistics service quality (LSQ) has significant impact on revenue and profitability. This paper presents the issue from the perspective of the customer, and explores the initial factors of LSQ based on the online shopping through in-depth interview and the Delphi method. The survey uses a standard 7-point Likert-type scale to measure the LSQ. Empirical research results are shown in detail to confirm seven LSQ dimensions with Chinese characteristics, including timeliness quality, personal contact quality, order quality, order discrepancy handling, order condition and convenience. Statistical analyses of the investigation were conducted to test the reliability and validity of the LSQ evaluation model.

Increasing evidence indicates adolescents are likely to occupy their leisure time with online games. This study investigates the influences of leisure satisfaction on life satisfaction among adolescent online gamers. The self-completed market survey questionnaire employed is comprised of two sections: the first is Internet usage frequency, while the second employs two measures-the Leisure Satisfaction Scale (LSS) and the Satisfaction with Life Scale (SWLS), Data were gathered in a medium-sized metropolitan section of north Taiwan and interviews took place at a Cyber Café. Youths (totaling 134) between the ages of 13 and 18 voluntarily participated in the research. Results revealed significant positive relationships between physiological and aesthetic dimensions of leisure satisfaction and life satisfaction. However, the educational dimension of leisure satisfaction has a significant negative influence on life satisfaction. Findings also reveal a significant negative relationship between web surfing frequency and life satisfaction in adolescents. This suggests possible explanations for these results and discusses the implications.

To describe pharmacy faculty members' use of the online social network Facebook and compare the perspectives of faculty members with and without Facebook profiles regarding student/faculty relationships. An electronic survey instrument was sent to full-time faculty members (n = 183) at 4 colleges of pharmacy in Ohio seeking their opinions on student/faculty relationships on Facebook. If respondents answered "yes" to having a Facebook profile, they were asked 14 questions on aspects of being "friends" with students. If respondents answered "no," they were asked 4 questions. Of the 95 respondents (52%) to the survey instrument, 44 faculty members (46%) had a Facebook profile, while 51 faculty members (54%) did not. Those who had a profile had been faculty members for an average of 8.6 years, versus 11.4 years for those who did not have a Facebook profile. Seventy-nine percent of faculty members who used Facebook were not "friends" with their students. The majority of respondents reported that they would decline/ignore a "friend" request from a student, or decline until after the student graduated. Although a limited number of faculty members had used Facebook for online discussions, teaching purposes, or student organizations, the majority of universities did not have policies on the use of social networking sites. Online social network sites are used widely by students and faculty members, which may raise questions regarding professionalism and appropriate faculty/student relationships. Further research should address the student/preceptor relationship, other online social networking sites, and whether students are interested in using these sites within the classroom and/or professional organizations.

Abstract Massively Multiplayer Online Roleplaying Games are extremely popular with millions and millions of players spending large portions of their free time in these virtual environments. Still the social value and the meaningfulness of the relationships formed within them are questioned by most non-gamers and even some gamers. In the past even academia was mainly concentrating on the negative aspects of gaming but lately...

Compared to traditional materials or journals, user-generated contents are not peer-reviewed. Lack of quality control and the explosive growth of web contents make the task of finding quality information on the web especially critical. The existence of new facilities for producing web contents such as forum makes this issue more significant. This study focuses on online forums threads or discussion, where the forums contain valuable human-generated information in a form of discussions. Due to the unique structure of the online forum pages, special techniques are required to organize and search for information in these forums. Quality biased retrieval is a retrieval approach that search for relevant document and prioritized higher quality documents. Despite major concern of quality content and recent development of quality biased retrieval, there is an urgent need to understand how quality content is being judged, for retrieval and performance evaluation purposes. Furthermore, even though there are various studies on the quality of information, there is no standard framework that has been established. The primary aim of this paper is to contribute to the understanding of human quality judgment in assessing online forum contents. The foundation of this study is to compare and evaluate different frameworks (for quality biased retrieval and information quality). This led to the finding that many quality dimensions are redundant and some dimensions are understood differently between different studies. We conducted a survey on crowdsourcing community to measure the importance of each quality dimensions found in various frameworks. Accuracy and ease of understanding are among top important dimensions while threads popularity and contents manipulability are among least important dimensions. This finding is beneficial in evaluating contents of online forum.

A wealth of data exist on knowledge, attitudes and practice related to contraceptive use; however, emotional aspects of relationships that may influence reproductive decision making are often overlooked. Data from the 2010 Family Health and Wealth Survey were used in bivariate and multinomial logistic regression analyses to identify associations between relationship quality and current contraceptive use among 698 married or cohabiting couples in Kumasi, Ghana. Four scales measuring commitment, trust, constructive communication and destructive communication, as well as a question about relationship satisfaction, were the indicators of relationship quality. Current contraceptive use was divided into three categories: no use, reliance on a method that can be used without the partner's awareness (the injectable, pill, IUD, implant and diaphragm) and use of a method that both partners are typically aware of (periodic abstinence, withdrawal, condoms and spermicide). Overall contraceptive use was low--22% of women said they were currently using any method. In general, respondents reported high levels of relationship quality. Women's relationship satisfaction scores were positively associated with use of awareness methods rather than nonuse (relative risk ratio, 1.2). Men's trust scores were positively associated with use of nonawareness methods rather than nonuse (1.1), and men's constructive communication scores were associated with use of both types of method rather than nonuse (1.1 for each). Couples' relationship quality appears to be an important element in their decision making regarding contraceptive use, and should be taken into consideration in the design and implementation of family planning programs and policy.

Both the Internet and social media have become important tools that patients and health professionals, including health professional students, use to obtain information and support their decision-making surrounding health care. Students in the health sciences require increased competence to select, appraise, and use online sources to adequately educate and support patients and advocate for patient needs and best practices. The purpose of this study was to ascertain if second year nursing students have the ability to critically identify and evaluate the quality of online health information through comparisons between student and expert assessments of selected online health information postings using an adapted Trust in Online Health Information scale. Interviews with experts provided understanding of how experts applied the selected criteria and what experts recommend for implementing nursing informatics literacy in curriculums. The difference between student and expert assessments of the quality of the online information is on average close to 40%. Themes from the interviews highlighted several possible factors that may influence informatics competency levels in students, specifically regarding the critical appraisal of the quality of online health information.

Using a daily diary method, this study examined concurrent and time-lagged relations between marital and parent-child relationship qualities, providing a test of the spillover and compensatory hypotheses. Additionally, this study tested both mothers’ and fathers’ depressive symptoms as moderators of these daily linkages. Participants were 203 families, in which mothers and fathers completed daily diaries for 15 days. At the end of each reporting day, parents independently rated the emotional quality of their relationship with their spouse and with their child that day. Controlling for global levels of marital satisfaction, marital conflict, and parenting, a positive association was found between mothers’ and fathers’ daily ratings of marital quality and their ratings of parent-child relationship quality, supporting the spillover hypothesis. When considering time-lagged relations, support was found for the compensatory hypothesis for mothers: lower levels of marital quality were related to increases in mother-child relationship quality from one day to the next. Further, both maternal and paternal depressive symptoms moderated the link between marital quality and the other parent’s relationship quality with their child. Whereas maternal depressive symptoms strengthened spillover relations for fathers on the next day, paternal depression was related to less spillover for mothers on the same day. Alternative models did not find evidence for parent-child relationship quality as a predictor of changes in marital quality on the next day. The findings underscore the importance of the quality of the marital relationship for predicting the quality of other family relationships. PMID:24821519
Full Text Available This paper studies the problem of dynamically modeling the quality of web service. The philosophy of designing practical web service recommender systems is delivered in this paper. A general system architecture for such systems continuously collects the user-service invocation records and includes both an online training module and an offline training module for quality prediction. In addition, we introduce matrix factorization-based online and offline training algorithms based on the gradient descent algorithms and demonstrate the fitness of this online/offline algorithm framework to the proposed architecture. The superiority of the proposed model is confirmed by empirical studies on a real-life quality of web service data set and comparisons with existing web service recommendation algorithms.

The Internet is an easily accessible source of information for women experiencing anxiety in pregnancy and/or postpartum to use when seeking health information. However, the Internet has several drawbacks, including inaccurate content that may be perceived as being accurate, non-biased, and evidence-based. Prior research indicates that anxiety and postpartum mental health websites have poor quality in terms of describing treatment options. There is a lack of research and knowledge in the area of perinatal anxiety, and an absence of research evaluating perinatal anxiety websites. The purpose of this study was to evaluate the quality of information regarding perinatal anxiety available on the Internet. Websites concerning perinatal anxiety were selected using the Google search engine. Each website was evaluated based on quality of health information, website usability, and readability. The 20 websites included in this study had low to moderate quality scores based on the DISCERN tool. There were no associations found between website order and website quality, or between website readability and website quality. Many websites had high PEMAT scores for the understandability section, which included content, style, and layout of information; however, most did not use visual aids to enhance comprehension. Most websites had low actionability scores, suggesting that information may not be useful in describing what actions may be taken to manage perinatal anxiety. This study highlights the need for high-quality websites concerning perinatal anxiety that are easy to navigate and provide the public with evidence-based information.
Full Text Available Online shopping has become popular over the years and is a widely used way to purchase goods and services. For online retailers to succeed, it is important that they have a quality website to attract and retain customers. The aim of this study was to investigate the construct validity of three respective measurement instruments related to website quality factors, namely; system, information and service quality factors, which may influence consumers within the online shopping environment in a South African context. Primary data was collected through self-administered questionnaires. The demographic and online shopping profile of the sample are presented and followed by confirmatory and exploratory factors analyses on the three instruments. The confirmatory factor analysis found poor fit for the original hypothesised models for each of the scales; further exploratory factor analyses revealed slightly different dimensionalities underlying the scales, yet these were still somewhat aligned with the theoretical framework from which the original scales were derived. Despite this, the study provides a platform for future revision of the scales and future research into website quality factors within the online shopping environment in a South African context.

Objective: This study employed a prospective design to examine the role of friend and partner relationship quality 1 year following substance use disorder treatment in the association between depressive symptoms at discharge from treatment and abstinence from substance use 2 years after treatment. Method: The sample consisted of 1,453 male veterans who used alcohol and at least one other substance in the 3 months before treatment admission, who completed treatment, and who were abstinent from substances during the 2 weeks before discharge. Results: Fewer depressive symptoms at treatment discharge predicted better relationship quality with friends and a partner at 1 -year follow-up, as well as abstinence from substance use at 2-year follow-up. Furthermore, friend and partner relationship quality at 1 year predicted abstinence from substance use at 2 years. Friend relationship quality at 1 year mediated part of the association between fewer depressive symptoms at treatment discharge and abstinence at 2-year follow-up. Conclusions: A stronger focus in treatment on reducing depressive symptoms and enhancing the quality of patients' relationships with their friends and partner may increase the likelihood of long-term abstinence.

Frequent pornography use is often negatively associated with marital quality. Recent research has argued that this negative association is particularly strong for those who are embedded in religious communities, likely due to the greater stigma and shame associated with viewing pornography. In order to test and extend this theory, the current study examined how religious service attendance moderates the link between parents' pornography consumption and four measures of parent-child relationship quality. Analyses of 2006 Portraits of American Life Study data (N = 2610) revealed that greater pornography viewing predicted negative outcomes on two out of four measures of parent-child relationship quality, while religious service attendance was associated with more positive parent-child relationship outcomes. Interaction effects, however, affirmed that the negative association between porn viewing frequency and three parent-child relationship outcomes was stronger for participants who attended religious services more often. Analyzing fathers (N = 771) and mothers (N = 904) separately revealed that the observed relationships held more consistently for fathers than mothers. Evidence for directionality was presented by incorporating re-interview data from 2012. While pornography use may be negatively associated with some aspects of parent-child relationship quality, this association was particularly strong for those embedded within religious communities, possibly owing to greater attendant guilt and shame.

Full Text Available Purpose: E-Government, as a new bond linking the government and the public, has gradually become the focus of innovation in government services. The paper focuses on the e-Government service quality issues from the perspective of users. Design/methodology/approach: From the aspects of online service quality perception and offline service quality perception, based on IS Success model and SERQUAL model, e-Government Services Quality model has been set up with information quality, system quality and service quality as key factors. Then, the survey method was applied to collect data and then to test the model. Findings: It was found that users’ perception of offline service quality has a significant effect on improving their perception of online service quality, and online service quality perception has a significant effect on public satisfaction of e-Government services; information clarity, system security and stability, interactive services and “one-stop” services all have a significant effect on public satisfaction of e-Government services. However, offline service quality perception has certain positive effect on public satisfaction of e-Government services but not dramatically. Research limitations/implications: Mobile e-Government as an important direction of the development of e-Government, in the future, we will study more about mobile e-Government services channels. Originality/value: This study further develops the theory of information system service quality, and also provides a theoretical reference for government departments. On the one hand, based on the characteristics of e-government system, information quality, system quality and service quality in the previous system service model are further discussed; on the other hand, both online and offline services are taken into consideration in the information system service model, thus establishing the e-government services quality model and making an in-depth study of the

In the context of the Affordable Care Act, there is extensive emphasis on making provider quality transparent and publicly available. Online public reports of quality exist, but little is known about how visitors find reports or about their purpose in visiting. To address this gap, we gathered website analytics data from a national group of online public reports of hospital or physician quality and surveyed real-time visitors to those websites. Websites were recruited from a national group of online public reports of hospital or physician quality. Analytics data were gathered from each website: number of unique visitors, method of arrival for each unique visitor, and search terms resulting in visits. Depending on the website, a survey invitation was launched for unique visitors on landing pages or on pages with quality information. Survey topics included type of respondent (eg, consumer, health care professional), purpose of visit, areas of interest, website experience, and demographics. There were 116,657 unique visitors to the 18 participating websites (1440 unique visitors/month per website), with most unique visitors arriving through search (63.95%, 74,606/116,657). Websites with a higher percent of traffic from search engines garnered more unique visitors (P=.001). The most common search terms were for individual hospitals (23.25%, 27,122/74,606) and website names (19.43%, 22,672/74,606); medical condition terms were uncommon (0.81%, 605/74,606). Survey view rate was 42.48% (49,560/116,657 invited) resulting in 1755 respondents (participation rate=3.6%). There were substantial proportions of consumer (48.43%, 850/1755) and health care professional respondents (31.39%, 551/1755). Across websites, proportions of consumer (21%-71%) and health care professional respondents (16%-48%) varied.

The childbirth constitutes a significant event in a woman's life and in the marital/ couple dyad. The changes which follow childbirth require re-organization of previous coping styles and development of new methods of adaptation, which proves difficult. The current study evaluated to what extent the development of postpartum depression symptoms in new mothers was associated with their level of satisfaction in marital relationship. The study included 100 women in their first month after delivery. The women completed questionnaires regarding postpartum depression (Postpartum Depression Screening Scale) and marital relationship quality (Marital Compatibility Questionnaire). There was a significant correlation between the level of postpartum depression and relationship quality. A greater severity of postpartum depression symptoms (sleeping/ eating disturbances, anxiety/insecurity, emotional lability, mental confusion, loss of self, guilt/ shame, suicidal thoughts) occurred in women who were less satisfied with their relationship, i.e., those who experienced a decreased level of intimacy, self-fulfillment and partner similarity, as well as a deeper sense of disillusionment. Women who declared deeper satisfaction with their relationship displayed a greater sense of mental well-being. No correlation was found between the occurrence of postpartum depression and socio-demographic factors (age, education level, place of residence) and factors associated with the subjects' childbearing history (number of children, number of pregnancies, history of miscarriage, family planning, prior diagnosis of depression, type of delivery, newborn's condition following birth, infant feeding method). Patients dissatisfied with the quality of their marital relationship experienced an increased severity of postpartum depression symptoms. Greater satisfaction with relationship quality was expressed by women in formalized relationships.
Full Text Available The effect of silviculture on wood quality has been approached from different perspectives. This relationship is being a critical concern of forest managers, landowners, and also researchers. Reliable information is needed to support forest managers in predicting the consequences of various silvicultural practices in terms of quantity and wood quality. Wood has beed used for a variety of products. Each product has particular requirements regarding quality. The variation of wood quality requirement allows industries to decide to use timber resource appropriate for their products. Silvicultural practives cover all treatments applied in forest stand management especially to improve the quality of stand, including manipulation of the availability of sunlight, nutrient and water by using several treatments such as thinning, control of spacing, fertilizing, and pruning. The quality of stand is aimed to achieve particular forest management objectives including higher wood quality. There is no broad generalization regarding the relation between silvicultural practice and wood quality. Many investigators showed positive results in relation to producing high quality of wood products, while other researchers revealed negative effects. Reliable information is needed to support forest managers in predicting the consequences of various silvicultural practices in relation to the wood quantity and quality. Continuous research is needed to find methods of producing wood of high quality based on silvicultural practices and genetic improvement which can be used in wider area by considering limitation including environment and geographic variation.

Full Text Available For online quality control of car engine production, pneumatic measurement instrument plays an unshakeable role in measuring diameters inside engine block because of its portability and high-accuracy. To the limitation of its measuring principle, however, the working space between the pneumatic device and measured surface is too small to require manual operation. This lowers the measuring efficiency and becomes an obstacle to perform automatic measurement. In this article, a high-speed, automatic measuring system is proposed to take the place of pneumatic devices by using a laser-based measuring unit. The measuring unit is considered as a set of several measuring modules, where each of them acts like a single bore gauge and is made of four laser triangulation sensors (LTSs, which are installed on different positions and in opposite directions. The spatial relationship among these LTSs was calibrated before measurements. Sampling points from measured shaft holes can be collected by the measuring unit. A unified mathematical model was established for both calibration and measurement. Based on the established model, the relative pose between the measuring unit and measured workpiece does not impact the measuring accuracy. This frees the measuring unit from accurate positioning or adjustment, and makes it possible to realize fast and automatic measurement. The proposed system and method were finally validated by experiments.

To assess whether experts can provide high-quality answers to occupational safety and health (OSH) questions in online Question & Answer (Q&A) networks. The authors evaluated the quality of answers provided by qualified experts in two Dutch online networks: ArboAntwoord and the Helpdesk of the Netherlands Center for Occupational Diseases. A random sample of 594 answers was independently evaluated by two raters using nine answer quality criteria. An additional criterion, the agreement of answers with the best available evidence, was explored by peer review of a sample of 42 answers. Reviewers performed an evidence search in Medline. The median answer quality score of ArboAntwoord (N=295) and the Netherlands Center for Occupational Diseases Helpdesk (N=299) was 8 of 9 (IQR 2). The inter-rater reliability of the first nine quality criteria was high (κ 0.82-0.90, p<0.05). A question answered by two or more experts had a greater probability of a high-quality score than questions answered by one expert (OR 4.9, 95% CI 2.7 to 9.0). Answers most often scored insufficient on the use of evidence to underpin the answer (36% and 38% for the networks, respectively) and on conciseness (35% and 31%, respectively). Peer review demonstrated that 43%-72% of the answers in both online networks were in complete agreement with the best available evidence. OSH experts are able to provide quality answers in online OSH Q&A networks. Our answer quality appraisal instrument was feasible and provided information on how to improve answer quality.

Many infertile couples experience psychological distress and suffer from impaired quality of life. Generally, when couples are dealing with uncontrolled events such as infertility, it is important to manage it well and to use the suitable coping style; so this can represent an example of attribution style. The purpose of this study is to investigate the quality of life, relationship beliefs and attribution style in infertile couples. This cross-sectional study consisted of 50 infertile couples, who were at least 18 years of age and could read and write in Persian. Participants provided demographic and general characteristics and completed the quality of life (SF-12), relationship belief inventory (RBI) and attribution style (ASQ) forms. Data was analyzed by the paired t test, Pearson correlation tests and multiple linear regression analysis, using SPSS version 22 statistical software. Overall, 50 infertile couples participated in our study. The males had a significantly higher score for quality of life compared to the females (P=0.019). In RBI subscales except "Disagreement is Destructive" all others significantly higher in wives than husbands. All subscales of RBI had a negative correlation with the quality of life. The quality of life had a significant correlation with positive internal (r=0.213, P=0.033). The adjusted regression model showed that the quality of life for males was higher than in females (β=-3.098, P=0.024). The current data indicate that in infertile couples, the husbands have a higher quality of life in comparison to their wives. Also, all subscales of relationship beliefs have a negative correlation with the quality of life, but in attribution style, just internal attribution style for positive events is associated with the quality of life. In general, there is a correlation between relationship beliefs and the quality of life in infertile couples. Copyright© by Royan Institute. All rights reserved.
Full Text Available Quality and productivity concepts were confusing and sometimes used interchangeably by experts both in industry and academics. Though researches, to some extent, tried to show the developments of quality and productivity, as yet, no research was devoted to study their evolution in a way to know how they reached into their existing form and their relationship, whether it existed. This study intends to disclose the reason behind the confusion and concept - intermix by studying the main advancements in the evolution of the two concepts. Their evolution is chronologically determined by grouping basic advancements in to distinct timeframes and their corresponding relationship is identified using natural selection and biased mutation approaches of evolution. The paper revealed that in the first period there was Seemingly Productivity; in the second Primarily Productivity; in the third Primarily Quality; in the fourth Primarily Quality-based Productivity (i.e. one after the other norm; and in the fifth period both quality and productivity will be equally primarily focus of firms (Primarily Quality and Productivity. Through logical justifications, observations made in the existing literature, and based on the nature of future competitiveness orientation, future relationship between the two concepts needs intelligence in that they will be equally, seemingly with trade-off, and concurrently important for organizational growth, agility, and excellence; one will never exist without the other, and after the other.

Background Online pharmacies are companies that sell pharmaceutical preparations, including prescription-only drugs, on the Internet. Very little is known about this phenomenon because many online pharmacies operate from remote countries, where legal bases and business practices are largely inaccessible to international research. Objective The aim of the study was to perform an up-to-date and comprehensive review of the scientific literature focusing on the broader picture of online pharmacies by scanning several scientific and institutional databases, with no publication time limits. Methods We searched 4 electronic databases up to January 2011 and the gray literature on the Internet using the Google search engine and its tool Google Scholar. We also investigated the official websites of institutional agencies (World Health Organization, and US and European centers for disease control and drug regulation authorities). We focused specifically on online pharmacies offering prescription-only drugs. We decided to analyze and report only articles with original data, in order to review all the available data regarding online pharmacies and their usage. Results We selected 193 relevant articles: 76 articles with original data, and 117 articles without original data (editorials, regulation articles, or the like) including 5 reviews. The articles with original data cover samples of online pharmacies in 47 cases, online drug purchases in 13, consumer characteristics in 15, and case reports on adverse effects of online drugs in 12. The studies show that random samples with no specific limits to prescription requirements found that at least some websites sold drugs without a prescription and that an online questionnaire was a frequent tool to replace prescription. Data about geographical characteristics show that this information can be concealed in many websites. The analysis of drug offer showed that online a consumer can get virtually everything.

Very little is known about this phenomenon because many online pharmacies operate from remote countries, where legal bases and business practices are largely inaccessible to international research. The aim of the study was to perform an up-to-date and comprehensive review of the scientific literature focusing on the broader picture of online pharmacies by scanning several scientific and institutional databases, with no publication time limits. We searched 4 electronic databases up to January 2011 and the gray literature on the Internet using the Google search engine and its tool Google Scholar. We also investigated the official websites of institutional agencies (World Health Organization, and US and European centers for disease control and drug regulation authorities). We focused specifically on online pharmacies offering prescription-only drugs. We decided to analyze and report only articles with original data, in order to review all the available data regarding online pharmacies and their usage. We selected 193 relevant articles: 76 articles with original data, and 117 articles without original data (editorials, regulation articles, or the like) including 5 reviews. The articles with original data cover samples of online pharmacies in 47 cases, online drug purchases in 13, consumer characteristics in 15, and case reports on adverse effects of online drugs in 12. The studies show that random samples with no specific limits to prescription requirements found that at least some websites sold drugs without a prescription and that an online questionnaire was a frequent tool to replace prescription. Data about geographical characteristics show that this information can be concealed in many websites. The analysis of drug offer showed that online a consumer can get virtually everything. Regarding quality of drugs, researchers very often found

Given its practicality, the internet is a primary resource for patients afflicted with diseases like peripheral neuropathy. Therefore, it is important that the readily available online resources on peripheral neuropathy are tailored to the general public, particularly concerning readability. Patient education resources were downloaded from the US National Library of Medicine, Mayo Clinic, National Institute of Neurological Disorders and Stroke, Neuropathy.org, GBS/CIDP Foundation International, Hereditary Neuropathy Foundation, Charcot-Marie-Tooth Association, Foundation for Peripheral Neuropathy, and Neuropathy Action Foundation websites. All patient education material related to peripheral neuropathy was evaluated for its level of readability using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level. The FRE scores averaged 43.4 with only the US National Library of Medicine scoring above 60 (76.5). The Flesch-Kincaid Grade Level scores averaged 11.0. All scores were above a seventh-grade level except the US National Library of Medicine, which had a score of a fifth-grade reading level. Most Americans may not fully benefit from patient education resources concerning peripheral neuropathy education on many of the websites. Only the US National Library of Medicine, which is written at a fifth-grade level, is likely to benefit the average American. © 2013 Peripheral Nerve Society.

Social scientific research on family life, religion, and spirituality tends to focus on global religiousness and spirituality with few studies seeking to understand interpersonal religious and spiritual contributors, namely sanctification and spiritual disclosure, from multiple family members' perspectives. This study explored 91 mother-college student and 64 father-college student dyads who rated their use of spiritual disclosure and theistic and nontheistic sanctification of the parent-child dyad in relation to parent-child relationship quality (e.g., parent-child relationship satisfaction and open communication). Results indicate significant positive links between higher levels of spiritual disclosure and greater theistic and nontheistic sanctification, for mothers, fathers, and their children. However, only greater nontheistic sanctification and higher levels spiritual disclosure were significantly related to increased parent-child relationship quality. Through use of Actor-Partner Interdependence Models (APIMs) results indicated unique contributions of spiritual disclosure to parent-child relationship quality above nontheistic sanctification for open communication in the family. However, full models, which included nontheistic sanctification and spiritual disclosure, predict college students' relationship satisfaction with their mothers and fathers. Implications for interpersonal religiousness and spirituality as contributors to familial relationship quality in research and practice are discussed. © 2013 American Psychological Association

Education in Quality Improvement for Pediatric Practice (EQIPP) is an online program designed to improve evidence-based care delivery by teaching front-line clinicians quality improvement (QI) skills. Our objective was to evaluate EQIPP data to characterize 1) participant enrollment, use patterns, and demographics; 2) changes in performance in clinical QI measures from baseline to follow-up measurement; and 3) participant experience. We conducted an observational study of EQIPP participants utilizing 1 of 3 modules (asthma, immunizations, gastroesophageal reflux disease) from 2009 to 2013. Enrollment and use, demographic, and quality measure data were extracted directly from the EQIPP system; participant experience was assessed via an optional online survey. Study participants (n = 3501) were diverse in their gender, age, and race; most were board certified. Significant quality gaps were observed across many of the quality measures at baseline; sizable improvements were observed across most quality measures at follow-up. Participants were generally satisfied with their experience. The most influential module elements were collecting and analyzing data, creating and implementing aim statements and improvement plans, and completing "QI Basics." Online educational programs, such as EQIPP, hold promise for front-line clinicians to learn QI. The sustainability of the observed improvements in care processes and their linkage to improvements in health outcomes are unknown and are an essential topic for future study.

To evaluate the association between self-reported sleep quality and levels of brain β-amyloid (Aβ) burden, and to determine the effect of the apolipoprotein E (APOE) ε4 allele on any associations found. This study is a cross-sectional analysis of 184 cognitively healthy men and women aged over 60 y. We measured sleep quality factors: specifically, sleep duration, latency (time taken to fall asleep), disturbances, efficiency, daytime dysfunction, and overall sleep quality, using the Pittsburgh Sleep Quality Index. All participants underwent Aβ positron emission tomography imaging for the quantification of brain Aβ burden and were APOE genotyped. Linear regression analyses were used to evaluate the relationship between sleep quality factors and brain Aβ burden, adjusting for age, body mass index, cardiovascular disease, and symptoms of depression, with APOE ε4 carriage entered as a moderator. Of the sleep factors, longer sleep latency was associated with higher levels of brain Aβ (B = 0.003 [standard error = 0.001], P = 0.02). APOE ε4 allele (carrier/noncarrier) did not moderate the relationship between sleep latency and brain Aβ burden. Our findings suggest a relationship between brain Aβ burden and sleep latency, independent of APOE ε4 genotype. © 2016 Associated Professional Sleep Societies, LLC.

The Internet is an easily accessible and commonly used source of health-related information, but evaluations of the quality of this information within the dental trauma field are still lacking. The aims of this study are (i) to present the most current scientific knowledge regarding mouth guards used in sport activities, (ii) to suggest a scoring system to evaluate the quality of information pertaining to mouth guard protection related to World Wide Web sites and (iii) to employ this scoring system when seeking reliable mouth guard-related websites. First, an Internet search using the keywords 'athletic injuries/prevention and control' and 'mouth protector' or 'mouth guards' in English was performed on PubMed, Cochrane, SvedMed+ and Web of Science to identify scientific knowledge about mouth guards. Second, an Internet search using the keywords 'consumer health information Internet', 'Internet information public health' and 'web usage-seeking behaviour' was performed on PubMed and Web of Science to obtain scientific articles seeking to evaluate the quality of health information on the Web. Based on the articles found in the second search, two scoring systems were selected. Then, an Internet search using the keywords 'mouth protector', 'mouth guards' and 'gum shields' in English was performed on the search engines Google, MSN and Yahoo. The websites selected were evaluated for reliability and accuracy. Of the 223 websites retrieved, 39 were designated valid and evaluated. Nine sites scored 22 or higher. The mean total score of the 39 websites was 14.2. Fourteen websites scored higher than the mean total score, and 25 websites scored less. The highest total score, presented by a Public Institution Web site (Health Canada), was 31 from a maximum possible score of 34, and the lowest score was 0. This study shows that there is a high amount of information about mouth guards on the Internet but that the quality of this information varies. It should be the responsibility

Anesthesiologists are frequently involved in efforts to meet perioperative quality metrics. The degree to which hospitals compete on publicly reported quality measures, however, is unclear. We hypothesized that hospitals in more competitive environments would be more likely to compete on quality and thus perform better on such measures. To test our hypothesis, we studied the relationship between competition and quality in hospitals providing procedural cardiac care and participating in a national quality database. For hospitals performing heart valve surgery (HVS) and delivering acute myocardial infarction (AMI) care in the Hospital Compare database, we assessed the degree of intrahospital competition using both geographical radius and federally defined metropolitan statistical area (MSA) to determine the degree of intrahospital competition. For each hospital, we then correlated the degree of competition with quality measure performance, mortality, patient volume, and per-patient Medicare costs for both HVS and AMI. Six hundred fifty-three hospitals met inclusion criteria for HVS and 1898 hospitals for AMI care. We found that for both definitions of competition, hospitals facing greater competition did not demonstrate better quality measure performance for either HVS or AMI. For both diagnoses, competition by number of hospitals correlated positively with cost: partial correlation coefficients = 0.40 (0.42 for MSA) (P competition among hospitals correlated overall with increased Medicare costs but did not predict better scores on publicly reported quality metrics. Our results suggest that hospitals do not compete meaningfully on publicly reported quality metrics or costs.

On-line monitoring of crystal size in the crystallization process is crucial to many pharmaceutical and fine-chemical industrial applications. In this paper, a novel method is proposed for the on-line monitoring of the cooling crystallization process of L-glutamic acid (LGA) using electrical impedance spectroscopy (EIS). The EIS method can be used to monitor the growth of crystal particles relying on the presence of an electrical double layer on the charged particle surface and the polarization of double layer under the excitation of alternating electrical field. The electrical impedance spectra and crystal size were measured on-line simultaneously by an impedance analyzer and focused beam reflectance measurement (FBRM), respectively. The impedance spectra were analyzed using the equivalent circuit model and the equivalent circuit elements in the model can be obtained by fitting the experimental data. Two equivalent circuit elements, including capacitance ( C 2 ) and resistance ( R 2 ) from the dielectric polarization of the LGA solution and crystal particle/solution interface, are in relation with the crystal size. The mathematical relationship between the crystal size and the equivalent circuit elements can be obtained by a non-linear fitting method. The function can be used to predict the change of crystal size during the crystallization process. (paper)

Full Text Available Abstract Background Japanese nurses are increasingly required to read published international research in clinical, educational, and research settings. Language barriers are a significant obstacle, and online machine translation (MT is a tool that can be used to address this issue. We examined the quality of Google Translate® (English to Japanese and Korean to Japanese, which is a representative online MT, using a previously verified evaluation method. We also examined the perceived usability and current use of online MT among Japanese nurses. Findings Randomly selected nursing abstracts were translated and then evaluated for intelligibility and usability by 28 participants, including assistants and research associates from nursing universities throughout Japan. They answered a questionnaire about their online MT use. From simple comparison of mean scores between two language pairs, translation quality was significantly better, with respect to both intelligibility and usability, for Korean-Japanese than for English-Japanese. Most respondents perceived a language barrier. Online MT had been used by 61% of the respondents and was perceived as not useful enough. Conclusion Nursing articles translated from Korean into Japanese by an online MT system could be read at an acceptable level of comprehension, but the same could not be said for English-Japanese translations. Respondents with experience using online MT used it largely to grasp the overall meanings of the original text. Enrichment in technical terms appeared to be the key to better usability. Users will be better able to use MT outputs if they improve their foreign language proficiency as much as possible. Further research is being conducted with a larger sample size and detailed analysis.

International literature has identified a stable correlation between problems in the sphere of adolescents' personal relationships and potential Internet dependence. The objective of this research is to verify in an Italian context the relationship among problematic Internet use (PIU), the quality of interpersonal relationships, and the cognitive strategies habitually used by adolescents to face daily problems. The participants in the research were 98 adolescents ages 14 to 19 (M = 16.28 years). The following instruments were administered to the participants: the Internet Addiction Test (IAT), the Test of Interpersonal Relationships (TRI); and the Children's Coping Strategies Checklist (CCSC). Parents of the participants were administered the Child Behavior Checklist (CBCL). Of the participants, 36.7% showed signs of PIU. These adolescents use the Internet for many hours per week; most utilize dysfunctional coping strategies and show worse interpersonal relations than peers who do not show signs of PIU.

The Net Promoter Score (NPS) is, according to Reichheld, the single most reliable indicator of company growth, and many companies use this recommendation-based technique for measuring customer loyalty. Despite its widespread adoption by many companies across multiple industries, the debate about NPS goes on. A major concern is that managers treat NPS as being equivalent across customers, which is often very misleading. By using a unique data set that combines customers' promoter scores and online word-of-mouth (eWOM) behavior, this research studies how individual customers' promoter scores are related to eWOM, including its relationship with the three categories of customers that are identified by the NPS paradigm (i.e., promoters, passives, and detractors). Based on a sample of 189 customers, their promoter scores and corresponding eWOM, the results show that there is a positive relationship between customers' promoter scores and the valence of online messages. Further, while detractors and promoters are homogeneous with respect to the valence of the eWOM messages they spread, passives show message valence heterogeneity. Thus, although passives, the largest group of customers, have no weight in calculating the NPS, our results reveal that companies should flag passives for further attention and action.

Associations between the quality of social relationships at work and mental and self-reported health were examined to assess whether these associations were independent of job strain. The study was based on cross-sectional survey data from 728 employees (response rate 58%) and included the Demand-Control-(Support) (DC-S) model, six items on the quality of social relationships at the workplace, the General Health Questionnaire (30), and an item on self-reported physical health. Logistic regression analyses were used. A first set of models were run with adjustment for age, sex, and socioeconomic group. A second set of models were run adjusted for the dimensions of the DC-S model. Positive associations were found between the quality of social relationships and mental health as well as self-rated physical health, and these associations remained significant even after adjustment for the dimensions. The findings add support to the Health and Safety Executive stress management standards on social relationships at the workplace.
Full Text Available Objective – To explore how and when individuals with chronic health conditions seek out health information online, and the challenges they encounter when doing so. Design – Qualitative study employing thematic analysis. Setting – Urban Western Australia. Subjects – 17 men and women between 19 and 85 years of age with at least 1 chronic health condition. Methods – Participants were recruited in late 2013 at nine local pharmacies, through local radio, media channels, and a university's social media channels. Participants were adult English speakers who had looked for information on their chronic health condition(s using the Internet. Semi-structured face-to-face interviews were conducted with each participant, audio recorded, and transcribed. The transcripts were coded in QSR Nvivo using two different processes – an initial data-driven inductive approach to coding, followed by a theory driven analysis of the data. Main Results – Three major themes emerged: trust, patient activation, and relevance. Many of the participants expressed trust both in health professionals and in the efficacy of search engines like Google. However, there was uncertainty about the quality of some of the health information sources found. Searching for information online was seen by some participants as a way to feel more empowered about their condition(s and treatment, but they reported frustration in finding information that was relevant to their specific condition(s given the volume of information available. Low health literacy emerged in participant interviews as an intrinsic barrier to effective online searches for health information, along with low patient motivation and lack of time. The many extrinsic barriers identified included difficulty determining the quality of information found, the accessibility of the information (e.g., journal paywalls, and poor relationships with health care providers. Conclusion – Individuals look for online health

Self-piercing riveting (SPR) has become a significant joining technique for the automotive applications of aluminium sheets. Quality control in this locale has progressed at an altogether more leisurely rate than other areas of mechanical joining (e.g. spotweld) and is underdeveloped. Testing the quality mechanical interlock is often achieved by destructive testing, which results in material and time wastage. The solution is online monitoring of the self-piercing riveting process to provide non-destructive testing of the mechanical interlock.

We explored the prospective, microlevel relationship between nightly sleep quality (SQ) and the subsequent day's stress on positive (PA) and negative affect (NA) as well as the moderating relationships between nightly SQ, subsequent stress, and subsequent PA on NA. We investigated whether age moderated these relationships. We collected 56 days of sleep, stress, and affect data using daily diary questionnaires (N = 552). We used multilevel modeling to assess relationships at the between- and within-person levels. Daily increases in SQ and decreases in stress interacted to predict higher daily PA and lower daily NA. Better SQ in older adults enhanced the benefits of PA on the stress-NA relationship more during times of low stress, whereas better sleep in younger adults enhanced the benefits of PA more during times of high stress. Between-person effects were stronger predictors of well-being outcomes than within-person variability. The combination of good SQ and higher PA buffered the impact of stress on NA. The moderating impact of age suggests that sleep and stress play different roles across adulthood. Targeting intervention and prevention strategies to improve SQ and enhance PA could disrupt the detrimental relationship between daily stress and NA. © The Author 2015.

A sustainable coal industry needs to achieve a number of objectives including improvements in utilization of deposits, energy efficiency, and environmental performance during combustion. The ''Clean Coal Concept'' promises to combine the secure and low cost electricity supply offered by hard coal and lignite with adequate environmental precautions. In this context, modern quality control systems, which are greatly based on the on-line analyzers, play an important role in achieving sustainability targets. This paper examines the possibility of using commercial on-line analysis systems for monitoring the mineral matter content of low quality lignite mined from the lignite basin of Megalopolis, Peloponnese, Greece. The effect of the accuracy of the on-line analyzers to process control, when used for the characterization of low rank coals with complex and variable composition, is investigated by carrying out numerous bench- and pilot-scale trials. Pilot-scale trials were based on a dual energy gamma-ray transmission analyzer, which was installed on the conveyor belt that transports lignite from the mine pit to the homogenization stockyard. All measurement data were compared to data gathered during the realisation of similar trials in the lignite mines of Ptolemais Basin, Northern Greece. Results indicated that the accuracy of the on-line measurements was not satisfactory and did not allow lignite quality monitoring in real time. The achieved inferior accuracy of the on-line measurement's accuracy, compared to previous applications at other mining sites, was related to the intense variation of the mineral matter content of lignite and lignite composition, which distorted the calibration of the analyzer. The latter is based on certain assumptions regarding the average mass absorption coefficient of the organic and mineral matter contained in the lignite. Further experimental work is needed to investigate solutions for successful implementation of

Full Text Available e-Service quality (eSQ is increasingly recognized as an important aspect, as well as the key to determining the competitive advantage and factor in the long-term retention of firms operating online. This study, therefore, is aimed at identifying the key determinants of eSQ among the small online apparel businesses in Malaysia. This study used a cross-sectional design, and data were collected from 765 customers who purchased apparel online at the point-of-purchase. Findings of this study indicate that “product information quality,” “website design,” “security and privacy,” and “expected consumer service” are the key determinants of eSQ among small online apparel businesses in Malaysia. The implication for the owner-managers of the apparel businesses in Malaysia is that they must be aware of the significance of the key eSQ indicators while designing their businesses, to attract and retain customers.

Improving diet quality while simultaneously reducing environmental impact is a critical focus globally. Metrics linking diet quality and sustainability have typically focused on a limited suite of indicators, and have not included food waste. To address this important research gap, we examine the relationship between food waste, diet quality, nutrient waste, and multiple measures of sustainability: use of cropland, irrigation water, pesticides, and fertilizers. Data on food intake, food waste, and application rates of agricultural amendments were collected from diverse US government sources. Diet quality was assessed using the Healthy Eating Index-2015. A biophysical simulation model was used to estimate the amount of cropland associated with wasted food. This analysis finds that US consumers wasted 422g of food per person daily, with 30 million acres of cropland used to produce this food every year. This accounts for 30% of daily calories available for consumption, one-quarter of daily food (by weight) available for consumption, and 7% of annual cropland acreage. Higher quality diets were associated with greater amounts of food waste and greater amounts of wasted irrigation water and pesticides, but less cropland waste. This is largely due to fruits and vegetables, which are health-promoting and require small amounts of cropland, but require substantial amounts of agricultural inputs. These results suggest that simultaneous efforts to improve diet quality and reduce food waste are necessary. Increasing consumers’ knowledge about how to prepare and store fruits and vegetables will be one of the practical solutions to reducing food waste. PMID:29668732

In previous work we have developed a diary instrument-the Social Rhythm Metric (SRM), which allows the assessment of lifestyle regularity-and a questionnaire instrument--the Pittsburgh Sleep Quality Index (PSQI), which allows the assessment of subjective sleep quality. The aim of the present study was to explore the relationship between lifestyle regularity and subjective sleep quality. Lifestyle regularity was assessed by both standard (SRM-17) and shortened (SRM-5) metrics; subjective sleep quality was assessed by the PSQI. We hypothesized that high lifestyle regularity would be conducive to better sleep. Both instruments were given to a sample of 100 healthy subjects who were studied as part of a variety of different experiments spanning a 9-yr time frame. Ages ranged from 19 to 49 yr (mean age: 31.2 yr, s.d.: 7.8 yr); there were 48 women and 52 men. SRM scores were derived from a two-week diary. The hypothesis was confirmed. There was a significant (rho = -0.4, p subjects with higher levels of lifestyle regularity reported fewer sleep problems. This relationship was also supported by a categorical analysis, where the proportion of "poor sleepers" was doubled in the "irregular types" group as compared with the "non-irregular types" group. Thus, there appears to be an association between lifestyle regularity and good sleep, though the direction of causality remains to be tested.

Full Text Available This paper shows the results of the empirical study conducted in 186 tourist accommodation businesses in Spain certified under the “Q for Tourist Quality”, own System Quality Management. It was raised with the purpose of analyzing the structure of the relationship between critical quality factors and results-social impact, how they operate and the level of their influence on obtaining these results within the company. Starting from a deep theoretical revision we propose a theoretical model together with the hypotheses to be tested, and we proceed to validation using the technique of Structural Equation Models. The results obtained show that companies wishing to improve their social impact should take into account that leadership is the most important factor to achieve it. Leadership indirectly affects the social impact through its influence on alliances and resources, quality policy/planning, personnel management and learning.
Full Text Available Posttraumatic stress disorder (PTSD in war veterans and its complex emotional and behavioral characteristics affect veterans’ partners and the quality of their relationships. Although most research focuses on the effects of veterans’ PTSD on their partners/wives and their relationships, not many findings have been established on partner adjustment and marriage quality when wives suffer from PTSD as well.The aim of the research was to examine the relationship between war-related posttraumatic stress symptoms and partner's marital satisfaction in couples where one or both partners suffer from PTSD.The Harvard Trauma Questionnaire and Dyadic Adjustment Scale encompassed 154 war veterans and their wives who had been treated at Mostar Clinical Hospital in Bosnia and Herzegovina for combat-related PTSD as well as 77 veterans who did not suffer from PTSD and their wives.Veterans’ PTSD is related to lower levels of marital adjustment of their wives. Marital adjustment was significantly lower in couples where both partners had PTSD compared with couples where only the veteran had PTSD or neither partner had PTSD. Female partner's marital adjustment is best explained by his avoidance symptoms and her own level of depressiveness and re-experiencing symptoms.The results highlight the importance of recognizing PTSD in wives of traumatized veterans as well as the importance of family approach in the treatment of PTSD.For the abstract or full text in other languages, please see Supplementary files under Reading Tools online
Full Text Available Background The aim of this study was to evaluate the occurrence and intensity of menopausal symptoms, taking into account the length of one’s relationship, its nature and one’s assessment of it. Participants and procedure The study included 200 women between the ages of 45 and 68, with secondary or higher education, married or in cohabiting relationships. Women were divided into three groups depending on the experience related to menopause: premenopause (46 respondents, perimenopause (75 respondents, and postmenopause (79 respondents. The study used a survey of self-design, the “Women’s Health” Questionnaire (WHQ by M. Hunter, and the “Partner Relations Questionnaire” (PFB by K. Hahlweg. Results Most menopausal symptoms – including those of the greatest severity – are experienced by women in perimenopausal and postmenopausal phases, but one’s own relationship’s assessment is the lowest in postmenopausal women. In this group of women, relevant and significant relations between the dimensions of the quality of the relationship and the menopausal symptoms are the most numerous. The most essential assessment was the one relating to intimacy – its poor evaluation is accompanied by higher intensity of experienced depression symptoms, somatic symptoms, and disorders of memory and concentration, sex and sleep, and also the sum of menopausal symptoms is higher. In all three groups, no significant differences in the severity of menopausal symptoms were observed between women in marital and cohabiting relationships. In women in the perimenopausal phase, the shorter the length of the relationship (its seniority, the greater is the severity of sexual dysfunction symptoms, whereas in women in the postmenopausal stage, along with the length of the relationship, the severity of psychological and somatic symptoms increases. Conclusions One should find that the perimenopausal and postmenopausal phases are particularly difficult for women

Engineering reliability typically refers to the probability that a system, or any of its components, will perform a required function for a stated period of time and under specified operating conditions. As such, reliability is inextricably linked with time-dependent quality concepts, such as maintaining a state of control and predicting the chances of losses from failures for quality risk management. Two popular current good manufacturing practice (cGMP) and quality risk management tools, failure mode and effects analysis (FMEA) and root cause analysis (RCA) are examples of engineering reliability evaluations that link reliability with quality and risk. Current concepts in pharmaceutical quality and quality management systems call for more predictive systems for maintaining quality; yet, the current pharmaceutical manufacturing literature and guidelines are curiously silent on engineering quality. This commentary discusses the meaning of engineering reliability while linking the concept to quality systems and quality risk management. The essay also discusses the difference between engineering reliability and statistical (assay) reliability. The assurance of quality in a pharmaceutical product is no longer measured only "after the fact" of manufacturing. Rather, concepts of quality systems and quality risk management call for designing quality assurance into all stages of the pharmaceutical product life cycle. Interestingly, most assays for quality are essentially static and inform product quality over the life cycle only by being repeated over time. Engineering process reliability is the fundamental concept that is meant to anticipate quality failures over the life cycle of the product. Reliability is a well-developed theory and practice for other types of manufactured products and manufacturing processes. Thus, it is well known to be an appropriate index of manufactured product quality. This essay discusses the meaning of reliability and its linkages with quality

A measure of Facebook-related mate-retention tactics was developed to investigate the relationship between online behaviors and intimate partner aggression. One hundred and seventy-seven young adults (65 men, 112 women) completed questionnaires that included measures of online and offline mate-retention tactics, Facebook jealousy, Facebook surveillance, and intimate partner violence. A factor analysis yielded four subscales for the Facebook Mate-Retention Tactic Inventory (FMRTI): Care and Affection, Jealousy and Surveillance, Possession Signals, and Punishment of Infidelity Threat. The FMRTI total scores were positively correlated with Facebook jealousy, Facebook surveillance, and use of offline mate-retention tactics. The Jealousy and Surveillance subscale uniquely predicted intimate partner psychological and physical aggression over and above existing measures. Facebook mate-retention tactics fully mediated the relation between Facebook jealousy and both intimate partner psychological and physical aggression. The current study provides preliminary evidence for conceptualizing Facebook as an environment for the use of mate-retention tactics that have real-life implications for intimate partner violence. © The Author(s) 2014.

Continuity of patient care is one of the cornerstones of primary care. To examine publicly available, Internet-based reviews of adult primary care physicians, specifically written by patients who report long-term relationships with their physicians. This substudy was nested within a larger qualitative content analysis of online physician ratings. We focused on reviews reflecting an established patient-physician relationship, that is, those seeing their physicians for at least 1 year. Of the 712 Internet reviews of primary care physicians, 93 reviews (13.1%) were from patients that self-identified as having a long-term relationship with their physician, 11 reviews (1.5%) commented on a first-time visit to a physician, and the remainder of reviews (85.4%) did not specify the amount of time with their physician. Analysis revealed six overarching domains: (1) personality traits or descriptors of the physician, (2) technical competence, (3) communication, (4) access to physician, (5) office staff/environment, and (6) coordination of care. Our analysis shows that patients who have been with their physician for at least 1 year write positive reviews on public websites and focus on physician attributes.

Introduction: Despite many advances in the treatment of chronic renal failure, the quality of sleep in patients who suffer from this disease is at the risk. The high prevalence of sleep disorders in hemodialysis patients, which is concomitant with physical, behavioral, and psychological problems, has always affected these patients' quality of life (QOL). This study aimed to determine the relationship between quality of sleep and quality of life in hemodialysis patients. Methods: By using a descriptive and correlational design, this study was conducted on 245 hemodialysis patients in 2012. Patients were selected by convenience sampling from the hemodialysis ward of four training hospitals of Tabriz and Maragheh. Quality of sleep was measured by the Pittsburgh Sleep Quality Index (PSQI), and the quality of life for patients was measured by the Kidney Disease Quality Of Life questionnaire (KDQOL-SF). Results: 83.3% of hemodialysis patients had poor quality of sleep. Poor quality of life was significantly associated with poor quality of sleep. There was a significant negative correlation between global PSQI and important aspects of quality of life including physical health, symptoms and problems, the impact of kidney disease on daily life, burden of kidney disease, mental health, social support, and sexual function. Conclusion: The low quality of sleep in hemodialysis patients has an effect on the deterioration of their quality of life. Therefore, training, counseling, and advocacy programs should be developed to improve the patients' quality of sleep and quality of life, especially those with lower education level and income, and older people.

Dietary modification is critical in the self-management of chronic kidney disease. The present study describes the accuracy, quality and health literacy demand of renal diet information for adults with kidney disease obtained from the Internet and YouTube (www.youtube.com). A comprehensive content analysis was undertaken in April and July 2015 of 254 eligible websites and 161 YouTube videos. The accuracy of the renal diet information was evaluated by comparing the key messages with relevant evidence-based guidelines for the dietary management of people with kidney disease. The DISCERN tool (www.discern.org.uk) was used to evaluate the quality of the material. Health literacy demand was evaluated using the Patient Education Material Assessment Tool (www.ahrq.gov/professionals/prevention-chronic-care/improve/self-mgmt/pemat/index.html) and seven validated readability calculators. The most frequent renal diet topic found online was generic dietary information for people with chronic kidney disease. The proportion of renal diet information obtained from websites that was accurate was 73%. However, this information was mostly of poor quality with extensive shortcomings, difficult to action and written with a high health literacy demand. By contrast, renal diet information available from YouTube was highly understandable and actionable, although only 18% of the videos were accurate, and a large proportion were of poor quality with extensive shortcomings. The most frequent authors of accurate, good quality, understandable, material were government bodies, dietitians, academic institutions and medical organisations. Renal diet information found online that is written by government bodies, dietitians, academic institutions and medical organisations is recommended. Further work is required to improve the quality and, most importantly, the actionability of renal diet information found online. © 2017 The British Dietetic Association Ltd.

Purpose: An important challenge facing online adaptive radiation therapy is the development of feasible and efficient quality assurance (QA). This project aimed to validate the deliverability of online adapted plans and develop a proof-of-concept online delivery monitoring system for online adaptive radiation therapy QA. Methods: The first part of this project benchmarked automatically online adapted prostate treatment plans using traditional portal dosimetry IMRT QA. The portal dosimetry QA results of online adapted plans were compared to original (unadapted) plans as well as randomly selected prostate IMRT plans from our clinic. In the second part, an online delivery monitoring system was designed and validated via a simulated treatment with intentional multileaf collimator (MLC) errors. This system was based on inputs from the dynamic machine information (DMI), which continuously reports actual MLC positions and machine monitor units (MUs) at intervals of 50 ms or less during delivery. Based on the DMI, the system performed two levels of monitoring/verification during the delivery: (1) dynamic monitoring of cumulative fluence errors resulting from leaf position deviations and visualization using fluence error maps (FEMs); and (2) verification of MLC positions against the treatment plan for potential errors in MLC motion and data transfer at each control point. Validation of the online delivery monitoring system was performed by introducing intentional systematic MLC errors (ranging from 0.5 to 2 mm) to the DMI files for both leaf banks. These DMI files were analyzed by the proposed system to evaluate the system’s performance in quantifying errors and revealing the source of errors, as well as to understand patterns in the FEMs. In addition, FEMs from 210 actual prostate IMRT beams were analyzed using the proposed system to further validate its ability to catch and identify errors, as well as establish error magnitude baselines for prostate IMRT delivery

The Internet is one of the most widely utilized resources for health-related information. Evaluation of the medical literature suggests that the quality and accuracy of these resources are poor and written at inappropriately high reading levels. The purpose of our study was to evaluate the quality, accuracy, and readability of online resources pertaining to hallux valgus. Two search terms ("hallux valgus" and "bunion") were entered into Google, Yahoo, and Bing. With the use of scoring criteria specific to hallux valgus, the quality and accuracy of online information related to hallux valgus was evaluated by 3 reviewers. The Flesch-Kincaid score was used to determine readability. Statistical analysis was performed with t tests and significance was determined by P values hallux valgus" (P = .045). Quality and accuracy were significantly higher in resources authored by physicians as compared to nonphysicians (quality, P = .04; accuracy, P hallux valgus is poor and written at inappropriate reading levels. Furthermore, the search term used, authorship, and presence of commercial bias influence the value of these materials. It is important for orthopaedic surgeons to become familiar with patient education materials, so that appropriate recommendations can be made regarding valuable resources.

In the Russian Federation recently quality assessment of educational services provided by state-accredited universities is carried out by the state represented by the Ministry of education and science. State universities have simulated internal systemseducation quality assessment in accordance with the methodology proposed by the Ministry of education and science. Currently more attention is paid to the independent assessment of education quality which is the basis of professional public accreditation. The project "EQUASP" financed within the framework of the TEMPUS programme is directed to the problem of implementing the methodology of the online model of independent higher education quality assessment in the practice of Russian universities. The proposed model for assessing the quality of education is based on usage of 5 standards. The authors have done a comparative analysis of the model of higher education quality assessment existing in Vyatka State University and the model of education quality assessing offered by European universities-participants of the project EQUASP. The authors have presented the main results of investigation of this problem and some suggestions for improving the model of education quality assessment used by Vyatka State University.

The redistribution of soil has a profound impact on its quality (defined as its ability to function within its ecosystem and within adjacent ecosystems) and ultimately on its productivity for crop growth. The application of 137 Cs-redistribution techniques to the study of erosion has yielded major new insights into the soil erosion-soil quality relationship. In highly mechanized agricultural systems, tillage erosion can be the dominant cause of soil redistribution; in other agroecosystems, wind and water erosion dominate. Each causal factor results in characteristic landscape-scale patterns of redistribution. In landscapes dominated by tillage redistribution, highest losses occur in shoulder positions (those with convex downslope curvatures); in water-erosion-dominated landscapes, highest losses occur where slope gradient and length are at a maximum. Major impacts occur through the loss of organically-enriched surface material and through the incorporation of possibly yield-limiting subsoils into the rooting zone of the soil column. The potential impact of surface soil losses and concomitant subsoil incorporation on productivity may be assessed by examining the pedological nature of the affected soils and their position in the landscape. The development of sound conservation policies requires that the soil erosion-quality relationship be rigorously examined in the full range of pedogenic environments, and future applications of the 137 Cs technique hold considerable promise for providing this comprehensive global database.

Objective: To determine the relationship between resilience and quality of life of diabetes patients controlling the effect of personal level (i.e., gender, age, and income) and disease-specific (i.e., duration of disease, and current glucose level) demographics. Study Design: Analytical study. Place and Duration of Study: Outpatient Departments of various hospitals in Islamabad and Rawalpindi, from October to November 2012. Methodology: Patients diagnosed with diabetes taking treatment in an outdoor patients facility were included. Patients with a major diabetes complications causing or coexistent with a physical disability, medical condition or psychiatric comorbidity were excluded. Informed consent was taken from patients before administration of questionnaires. The patients were asked to respond to a demographic sheet, State-Trait resilience inventory, and WHO-Quality of Life BREF. Statistical testing was conducting using bivariate correlation, Mann-Whitney U-test, and multiple linear regression analysis for moderation testing. Results: There were 242 patients including (n=108, 44% females; and n=134, 56% males) aged 17 - 85 years with mean of 44.56 +- 16.56 years. Trait resilience predicted all aspects of quality of life of diabetic patients (b range = 0.30 to 0.42, p < .01) and explained 17% variance in physical functioning, 29% in psychological functioning, 17% in environmental functioning, 30% in social dimension, and 29% in overall quality of life. Duration of diabetes moderated effect of state resilience on all aspects of quality of life (b interaction range = 0.20 to 0.26, p < .05) and explained an additional 4% variance in physical functioning, 5% in psychological functioning, 3% in environmental functioning, 5% in social dimension, and 4% in overall quality of life of diabetics. Conclusion: Trait resilience has unconditional positive effect on all aspect of quality of life. Long standing diabetics may benefit from intervention addressing state

To evaluate the quality and readability of online information on ureteral stents. Google.com was queried using the search terms "ureteric stent", "ureteral stent", "double J stent" and, "Kidney stent" derived from Google AdWords. Website popularity was determined using Google Rank and the Alexa tool. Website quality assessment was performed using the following criteria: Journal of the American Medical Association (JAMA) benchmarks, Health on the Net (HON) criteria, and a customized DISCERN questionnaire. The customized DISCERN questionnaire was developed by combining the short validated DISCERN questionnaire with additional stent-specific items including definition, placement, complications, limitations, removal and "when to seek help". Scores related to stent items were considered as the "stent score" (SS). Readability was evaluated using five readability tests. Thirty-two websites were included. The mean customized DISCERN score and "stent score" were 27.1 ± 7.1 (maximum possible score = 59) and 14.6 ± 3.8 (maximum possible score = 24), respectively. A minority of websites adequately addressed "stent removal" and "when to seek medical attention". Only two websites (6.3%) had HON certification (drugs.com, radiologyinfo.org) and only one website (3.3%) met all JAMA criteria (bradyurology.blogspot.com). Readability level was higher than the American Medical Association recommendation of sixth-grade level for more than 75% of the websites. There was no correlation between Google rank, Alexa rank, and the quality scores (P > 0.05). Among the 32 most popular websites on the topic of ureteral stents, online information was highly variable. The readability of many of the websites was far higher than standard recommendations and the online information was questionable in many cases. These findings suggest a need for improved online resources in order to better educate patients about ureteral stents and also should inform physicians that popular websites may

Patients use online consumer ratings to identify high-performing physicians, but it is unclear if ratings are valid measures of clinical performance. We sought to determine whether online ratings of specialist physicians from 5 platforms predict quality of care, value of care, and peer-assessed physician performance. We conducted an observational study of 78 physicians representing 8 medical and surgical specialties. We assessed the association of consumer ratings with specialty-specific performance scores (metrics including adherence to Choosing Wisely measures, 30-day readmissions, length of stay, and adjusted cost of care), primary care physician peer-review scores, and administrator peer-review scores. Across ratings platforms, multivariable models showed no significant association between mean consumer ratings and specialty-specific performance scores (β-coefficient range, -0.04, 0.04), primary care physician scores (β-coefficient range, -0.01, 0.3), and administrator scores (β-coefficient range, -0.2, 0.1). There was no association between ratings and score subdomains addressing quality or value-based care. Among physicians in the lowest quartile of specialty-specific performance scores, only 5%-32% had consumer ratings in the lowest quartile across platforms. Ratings were consistent across platforms; a physician's score on one platform significantly predicted his/her score on another in 5 of 10 comparisons. Online ratings of specialist physicians do not predict objective measures of quality of care or peer assessment of clinical performance. Scores are consistent across platforms, suggesting that they jointly measure a latent construct that is unrelated to performance. Online consumer ratings should not be used in isolation to select physicians, given their poor association with clinical performance.
Background The online health care community is not just a place for the public to share physician reviews or medical knowledge, but also a physician-patient communication platform. The medical resources of developing countries are relatively inadequate, and the online health care community is a potential solution to alleviate the phenomenon of long hospital queues and the lack of medical resources in rural areas. However, the success of the online health care community depends on online contributions by physicians. Objective The aim of this study is to examine the effect of incentive mechanisms on physician’s online contribution behavior in the online health community. We addressed the following questions: (1) from which specialty area are physicians more likely to participate in online health care community activities, (2) what are the factors affecting physician online contributions, and (3) do incentive mechanisms, including psychological and material rewards, result in differences of physician online contributions? Methods We designed a longitudinal study involving a data sample in three waves. All data were collected from the Good Doctor website, which is the largest online health care community in China. We first used descriptive statistics to investigate the physician online contribution behavior in its entirety. Then multiple linear and quadratic regression models were applied to verify the causal relationship between rewards and physician online contribution. Results Our sample included 40,300 physicians from 3607 different hospitals, 10 different major specialty areas, and 31 different provinces or municipalities. Based on the multiple quadratic regression model, we found that the coefficients of the control variables, past physician online contributions, doctor review rating, clinic title, hospital level, and city level, were .415, .189, –.099, –.106, and –.143, respectively. For the psychological (or material) rewards, the standardized

Full Text Available Online social network is one of the biggest Internet phenomenon, which has attracted the interest of many marketers and psychologists who wanted to understand social network users’ behavior. Recognizing the lack of theoretical and empirical attention that has been given to this field, especially in Vietnam market, this study was conducted to examine the relationships among social benefits, online social network dependency, satisfaction, and youth’s habit formation in the context of Facebook. The findings of the study of 200 Facebook users indicated that the interrelationship among four factors of social benefits, online social network dependency, satisfaction, and habit formation affect each other. Indeed, dependency on online social network among the youth whose age ranged from 16 to 24 years old is significantly affected by social benefits factor and leads to the formation of habit. In addition, satisfaction plays a role in determining habitual Facebook use. This paper discusses theoretical and practical implication in marketing and psychology field.

The first years of life are typically shrouded by infantile amnesia, but there is enormous variability between adults in how early and how much they can remember from this period. This study examined one possible factor affecting this variability: whether the perceived quality of parent-child relationships is associated with the number of early memories young adults can retrieve, and their age at the time of their first memory. We found such associations but they were qualified by parent gender. Mother-child relationships that were more affectively intense (greater social support but also more negative interchanges) were associated with recalling more early memories, although paternal companionship was most associated with how early an individual's first memory was. Affective tone of retrieved memories was also assessed, and a greater proportion of affectively positive memories (as well as fewer affectively neutral memories for males) was associated with high parental involvement in children's lives.

Though it is known that different familial relationships influence one another (e.g., Yu & Gamble, 2008) the influence of outside relationships (i.e., peers) on family dynamics (i.e., sibling relationships) is less clear. Thus, the authors examined the association differential peer experiences had on the conflict frequency, conflict intensity, and relationship quality of the sibling relationship. A 1-year longitudinal design measured first-born siblings in Grades 8, 10, and 12 along with their second-born siblings. In the first year, participants were brought to the university to complete questionnaires and in the following year, siblings again participated by completing online questionnaires at home. Results partially confirmed the study hypotheses that adolescents would show greater sibling conflict and poorer relationship quality with greater peer group differences, revealing that when peer group differences between siblings were greater, the youngest siblings reported more intense sibling conflicts (pe = -.10 p siblings reported greater relationship positivity (pe = .13 p siblings' differential experiences beyond familial influence to focus on outside sources to better understand developmental fluctuations in siblings' relationships.

The Internet offers an easy and quick access to a vast amount of patient information. However, several studies point to the poor quality of many websites and the resulting hazards of false information. The aim of this study was to assess quality of information on thyroid cancer. A patients' search for information about thyroid cancer on German websites was simulated using the search engine Google and the patient portal "Patienten-Information.de". The websites were assessed using a standardized instrument with formal and content aspects from the German Cancer Society. Supporting the results of prior studies that analysed patient information on the Internet, the data showed that the quality of patient information on thyroid cancer is highly heterogeneous depending on the website providers. The majority of website providers are represented by media and health providers other than health insurances, practices and professionals offering patient information of relatively poor quality. Moreover, most websites offer patient information of low-quality content. Only a few trustworthy, high-quality websites exist. Especially Google, a common search engine, focuses more on the dissemination of information than on quality aspects. In order to improve the patient information from the Internet, the visibility of high-quality websites must be improved. For that, education programs to improve patients' eHealth literacy are needed. A quick and easy evaluation tool for online information suited for patients should be implemented, and patients should be taught to integrate such a tool into their research process.

The rapid increase in the use of the Internet for continuing education by physicians suggests the need to define quality criteria for accredited online modules. Continuing medical education (CME) directors from Canadian medical schools and academic researchers participated in a consensus process, Modified Nominal Group Technique, to develop agreement on the most important quality criteria to guide module development. Rankings were compared to responses to a survey of a subset of Canadian Medical Association (CMA) members. A list of 17 items was developed, of which 10 were deemed by experts to be important and 7 were considered secondary. A quality module would: be needs-based; presented in a clinical format; utilize evidence-based information; permit interaction with content and experts; facilitate and attempt to document practice change; be accessible for later review; and include a robust course evaluation. There was less agreement among CMA members on criteria ranking, with consensus on ranking reached on only 12 of 17 items. In contrast to experts, members agreed that the need to assess performance change as a result of an educational experience was not important. This project identified 10 quality criteria for accredited online CME modules that representatives of Canadian organizations involved in continuing education believe should be taken into account when developing learning products. The lack of practitioner support for documentation of change in clinical behavior may suggest that they favor traditional attendance- or completion-based CME; this finding requires further research.

The biggest e-Commerce challenge to understand their market is to chart their level of service quality according to customer perception. The opportunities to collect user perception through online user review is considered faster methodology than conducting direct sampling methodology. To understand the service quality level, sentiment analysis methodology is used to classify the reviews into positive and negative sentiment for five dimensions of electronic service quality (e-Servqual). As case study in this research, we use Tokopedia, one of the biggest e-Commerce service in Indonesia. We obtain the online review comments about Tokopedia service quality during several month observations. The Naïve Bayes classification methodology is applied for the reason of its high-level accuracy and support large data processing. The result revealed that personalization and reliability dimension required more attention because have high negative sentiment. Meanwhile, trust and web design dimension have high positive sentiments that means it has very good services. The responsiveness dimension have balance sentiment positive and negative.

The present work describes an online patient dosimetry and an image quality audit system in digital radiology. the system allows auditing of different parameters depending on contents of DICOM (Digital Imaging and Communication in Medicine) header. For the patient dosimetry audit, current mean values of entrance surface dose (ESD) were compared with local and national reference values (RVs) for the specific examination type evaluated. Mean values exceeding the RV trigger an alarm signal and then an evaluation of the technical parameters, operational practice and image quality starts, using data available in the DICOM header to derive any abnormal settings or performance to obtain the image. the X-ray tube output for different kVp values is measured periodically, allowing for the automatic calculation of the ESD. The system also allows for image quality audit linking it with the dose imparted and other technical parameters if the alarm condition if produced. Results and advantages derived from this online quality control are discussed. (Author) 5 refs

The online health care community is not just a place for the public to share physician reviews or medical knowledge, but also a physician-patient communication platform. The medical resources of developing countries are relatively inadequate, and the online health care community is a potential solution to alleviate the phenomenon of long hospital queues and the lack of medical resources in rural areas. However, the success of the online health care community depends on online contributions by physicians. The aim of this study is to examine the effect of incentive mechanisms on physician's online contribution behavior in the online health community. We addressed the following questions: (1) from which specialty area are physicians more likely to participate in online health care community activities, (2) what are the factors affecting physician online contributions, and (3) do incentive mechanisms, including psychological and material rewards, result in differences of physician online contributions? We designed a longitudinal study involving a data sample in three waves. All data were collected from the Good Doctor website, which is the largest online health care community in China. We first used descriptive statistics to investigate the physician online contribution behavior in its entirety. Then multiple linear and quadratic regression models were applied to verify the causal relationship between rewards and physician online contribution. Our sample included 40,300 physicians from 3607 different hospitals, 10 different major specialty areas, and 31 different provinces or municipalities. Based on the multiple quadratic regression model, we found that the coefficients of the control variables, past physician online contributions, doctor review rating, clinic title, hospital level, and city level, were .415, .189, -.099, -.106, and -.143, respectively. For the psychological (or material) rewards, the standardized coefficient of the main effect was 0.261 (or 0

Bidirectional pathways between twin relationship quality and friendship quality were investigated in a large longitudinal twin cohort. We examined negative and positive relationship features in 313 monozygotic (MZ) twins and 238 same-sex dizygotic (DZ) twins from ages 13 to 14 years, using latent structural modeling. Results showed stronger stability of the twin relationship quality compared to friendship quality. Positive features in the sibling relationship were associated with increased positive features in the relationship with the best friend a year later. In contrast, no significant association between negative sibling relationship features and change in negative friendship quality features was found. These findings speak to the important role of the sibling relationship in the development of good quality friendship relations in twins.

Peer-to-peer collaboration within integrated health systems requires a mechanism for sharing quality improvement lessons. The Veterans Health Administration (VA) developed online compendia of tools linked to specific cancer quality indicators. We evaluated awareness and use of the toolkits, variation across facilities, impact of social marketing, and factors influencing toolkit use. A diffusion of innovations conceptual framework guided the collection of user activity data from the Toolkit Series SharePoint site and an online survey of potential Lung Cancer Care Toolkit users. The VA Toolkit Series site had 5,088 unique visitors in its first 22 months; 5% of users accounted for 40% of page views. Social marketing communications were correlated with site usage. Of survey respondents (n = 355), 54% had visited the site, of whom 24% downloaded at least one tool. Respondents' awareness of the lung cancer quality performance of their facility, and facility participation in quality improvement collaboratives, were positively associated with Toolkit Series site use. Facility-level lung cancer tool implementation varied widely across tool types. The VA Toolkit Series achieved widespread use and a high degree of user engagement, although use varied widely across facilities. The most active users were aware of and active in cancer care quality improvement. Toolkit use seemed to be reinforced by other quality improvement activities. A combination of user-driven tool creation and centralized toolkit development seemed to be effective for leveraging health information technology to spread disease-specific quality improvement tools within an integrated health care system.

The purpose of this study was to assess the quality of information available to patients on the Internet when using popular search engines to search the term "hip arthroscopy." We analyzed the quality and content of information about hip arthroscopy (HA) on the first 50 websites returned by the search engines Google and Bing for the search term "hip arthroscopy." The sites were categorized by type, and quality and content were measured using the DISCERN score, along with an HA-specific content score. The HA-specific content score was used to assess each website for the presence or absence of 19 topics about HA determined to be important for a patient seeking information about the procedure. The Health on the Net Code (HONcode) status of each website was also noted. The mean DISCERN score for all websites analyzed was 39.5, considered "poor," while only 44.6% of sites were considered "fair" or "good." Governmental and nonprofit organization (NPO) websites had the highest average DISCERN score. The mean HA-specific content score was 8.6 (range, 2 to 16). The commercial website category had the highest average HA-specific content score, followed by the governmental and NPO category. Sites that bore the HONcode certification obtained significantly higher DISCERN scores than those without the certification (P = .0032) but did not obtain significantly higher HA-specific content scores. "Hip arthroscopy" is a fairly general term, and there is significant variability in the quality of HA information available online. The HONcode is useful to identify quality patient information websites; however, it is not commonly used in HA-specific websites and does not encompass all quality websites about HA. This study increases awareness of the quality of information on HA available online. Copyright © 2016 Arthroscopy Association of North America. Published by Elsevier Inc. All rights reserved.

Cross-sectional and experimental research has demonstrated an association between emotional suppression and IBS. However, the relationship is not well understood. To examine the relationships between emotional suppression, we compare the measures of beliefs about emotions and quality of life in irritable bowel syndrome (IBS) with healthy controls. Online questionnaires measured beliefs about emotions, emotional suppression and IBS-related quality of life in participants with (n = 87) and without (n = 37) IBS. Mediation analyses and group comparisons were used to explore the role of emotional suppression and beliefs about emotions in this sample. IBS participants held significantly more beliefs about the unacceptability of emotions compared to healthy controls despite no differences in emotional suppression. The relationship between beliefs about emotions and quality of life was not mediated by emotional suppression. However, the relationship between emotional suppression and quality of life was mediated by beliefs about emotions. The findings suggest a role of beliefs about emotions and emotional suppression in IBS, where emotional suppression may relate to changes in beliefs about emotions and consequently quality of life. This is discussed in relation to the cognitive-behavioural model of medically unexplained symptoms.

Today, microbial drinking water quality is monitored through either time-consuming laboratory methods or indirect on-line measurements. Results are thus either delayed or insufficient to support proactive action. A novel, optical, on-line bacteria sensor with a 10-minute time resolution has been developed. The sensor is based on 3D image recognition, and the obtained pictures are analyzed with algorithms considering 59 quantified image parameters. The sensor counts individual suspended particles and classifies them as either bacteria or abiotic particles. The technology is capable of distinguishing and quantifying bacteria and particles in pure and mixed suspensions, and the quantification correlates with total bacterial counts. Several field applications have demonstrated that the technology can monitor changes in the concentration of bacteria, and is thus well suited for rapid detection of critical conditions such as pollution events in drinking water.

(2002. To this end, using Oxford Proficiency test 50 (out of 70 female senior M.A. students of translation were selected and they were assigned to two groups: Online and hardcopy, using systematic sampling. Next, an English text was selected as the reference text. This reference text was given to three translators: 1 A male English translation expert with a Ph.D. degree in Computational Linguistics (Ref. 1; 2 A female English translation expert with an M.A. degree working at an English Translation Center and with more than 5 years of experience (Ref. 2, and 3 A male Ph.D. candidate in English translation (Ref. 3. These three versions were used as reference Persian standard translations to be entered into Bleu. Later, the English text was given to the hardcopy and online groups. Then, the translations of the participants were compared with the three reference Persian translations using Bleu. The time taken by each student to translate the text into Persian was also recorded. The results indicated that there was no statistically significant difference between the translations of the hardcopy and online groups from fluency/precision points of view. Comparison of the speed of translation in the two groups indicated that the online group was meaningfully faster. The possible beneficiaries of the findings of this research can be university professors, policy makers, and students in the realm of translation.

Suppression of undesirable emotions, as well as beliefs about the unacceptability of experiencing and expressing emotions, have both been shown to be related to poorer health-related outcomes in several clinical groups. Potential models through which these variables relate have yet to be tested in those with irritable bowel syndrome (IBS) and are therefore examined in the current article. Online questionnaires were administered to people with IBS (n = 84) to test a mediation model in which beliefs about the unacceptability of emotions are associated with greater emotional suppression, which in turn relates to increased affective distress and consequently poorer quality of life. An alternate model to test the direction of effect along with two further models using support-seeking as mediators of the same predictor and outcome were also tested. Emotional suppression and affective distress (in that particular order) mediate the relationship between beliefs about emotions and quality of life IBS. The models using support-seeking as mediators of the relationship between beliefs about emotions and the two outcomes were not supported. These findings suggest a role for emotional processing in medically unexplained symptoms and imply the need to address such beliefs about emotions in psychological therapies.

Emotional expression is highly valued in individualistic cultures, whereas emotional restraint is prioritized in collectivistic cultures. We hypothesized that high-quality relationships in these cultures would exhibit the forms of support provision congruent with their respective expectations. Study 1 examined support transactions among friends in response to a laboratory stressor and found that objectively judged relationship quality (RQ) more strongly positively predicted emotion-focused support provision behaviors by European Americans than by Asian Americans. Study 2, a questionnaire study, found that self-reported RQ predicted emotion-focused support provision more strongly among European Americans than among Japanese. Study 3 investigated more indirect forms of support and found that RQ more strongly predicted worrying about and monitoring close others enduring stressors and spending time with them without talking about the stressor among Asian Americans compared with European Americans. These findings suggest that RQ is expressed in terms of support provision in culturally normative ways. © 2015 by the Society for Personality and Social Psychology, Inc.

Full Text Available Online social networking usage is growing rapidly, especially among at-risk populations, such as men who have sex with men (MSM. However, little research has studied the relationship between online social networking usage and sexual risk behaviors among at-risk populations. One hundred and eighteen Facebook-registered MSM (60.1% Latino, 28% African American; 11.9% other were recruited from online (social networking websites and banner advertisements and offline (local clinics, restaurants and organizations venues frequented by minority MSM. Inclusion criteria required participants to be men who were 18 years of age or older, had had sex with a man in the past 12 months, were living in Los Angeles, and had a Facebook account. Participants completed an online survey on their social media usage and sexual risk behaviors. Results from a multivariable regression suggest that number of sexual partners met from online social networking technologies is associated with increased: 1 likelihood of having exchanged sex for food, drugs, or a place to stay within the past 3 months; 2 number of new partners within the past 3 months; 3 number of male sex partners within the past 3 months; and 4 frequency of engaging in oral sex within the past 3 months, controlling for age, race, education, and total number of sexual partners. Understanding the relationship between social media sex-seeking and sexual risk behaviors among at-risk populations will help inform population-focused HIV prevention and treatment interventions.
Ground-water quality and associated geologic characteristics may affect the feasibility of aquifer thermal energy storage (ATES) system development in any hydrologic region. This study sought to determine the relationship between ground-water quality parameters and the regional potential for ATES system development. Information was collected from available literature to identify chemical and physical mechanisms that could adversely affect an ATES system. Appropriate beneficiation techniques to counter these potential geochemical and lithologic problems were also identified through the literature search. Regional hydrology summaries and other sources were used in reviewing aquifers of 19 drainage regions in the US to determine generic geochemical characteristics for analysis. Numerical modeling techniques were used to perform geochemical analyses of water quality from 67 selected aquifers. Candidate water resources regions were then identified for exploration and development of ATES. This study identified six principal mechanisms by which ATES reservoir permeability may be impaired: (1) particulate plugging, (2) chemical precipitation, (3) liquid-solid reactions, (4) formation disaggregation, (5) oxidation reactions, and (6) biological activity. Specific proven countermeasures to reduce or eliminate these effects were found. Of the hydrologic regions reviewed, 10 were identified as having the characteristics necessary for ATES development: (1) Mid-Atlantic, (2) South-Atlantic Gulf, (3) Ohio, (4) Upper Mississippi, (5) Lower Mississippi, (6) Souris-Red-Rainy, (7) Missouri Basin, (8) Arkansas-White-Red, (9) Texas-Gulf, and (10) California.

We assessed the utility of online fluorescence spectroscopy for the real-time evaluation of the microbial quality of untreated drinking water. Online fluorimeters were installed on the raw water intake at four groundwater-derived UK public water supplies alongside existing turbidity sensors that are used to forewarn of the presence of microbial contamination in the water industry. The fluorimeters targeted fluorescent dissolved organic matter (DOM) peaks at excitation/emission wavelengths of 280/365 nm (tryptophan-like fluorescence, TLF) and 280/450 nm (humic-like fluorescence, HLF). Discrete samples were collected for Escherichia coli, total bacterial cell counts by flow cytometry, and laboratory-based fluorescence and absorbance. Both TLF and HLF were strongly correlated with E. coli (ρ = 0.71-0.77) and total bacterial cell concentrations (ρ = 0.73-0.76), whereas the correlations between turbidity and E. coli (ρ = 0.48) and total bacterial cell counts (ρ = 0.40) were much weaker. No clear TLF peak was observed at the sites and all apparent TLF was considered to be optical bleed-through from the neighbouring HLF peak. Therefore, a HLF fluorimeter alone would be sufficient to evaluate the microbial water quality at these sources. Fluorescent DOM was also influenced by site operations such as pump start-up and the precipitation of cations on the sensor windows. Online fluorescent DOM sensors are a better indicator of the microbial quality of untreated drinking water than turbidity and they have wide-ranging potential applications within the water industry.

We have studied the dynamics of water quality in three karst springs taking advantage of new technological developments that enable high-resolution measurements of bacterial load (total cell concentration: TCC) as well as online measurements of abiotic parameters. We developed a novel data analysis approach, using self-organizing maps and non-linear projection methods, to approximate the TCC dynamics using the multivariate data sets of abiotic parameter time-series, thus providing a method that could be implemented in an online water quality management system for water suppliers. The (TCC) data, obtained over several months, provided a good basis to study the microbiological dynamics in detail. Alongside the TCC measurements, online abiotic parameter time-series, including spring discharge, turbidity, spectral absorption coefficient at 254nm (SAC254) and electrical conductivity, were obtained. High-density sampling over an extended period of time, i.e. every 45min for 3months, allowed a detailed analysis of the dynamics in karst spring water quality. Substantial increases in both the TCC and the abiotic parameters followed precipitation events in the catchment area. Differences between the parameter fluctuations were only apparent when analyzed at a high temporal scale. Spring discharge was always the first to react to precipitation events in the catchment area. Lag times between the onset of precipitation and a change in discharge varied between 0.2 and 6.7h, depending on the spring and event. TCC mostly reacted second or approximately concurrent with turbidity and SAC254, whereby the fastest observed reaction in the TCC time series occurred after 2.3h. The methodological approach described here enables a better understanding of bacterial dynamics in karst springs, which can be used to estimate risks and management options to avoid contamination of the drinking water.

To apply an integrated quality assessment strategy to investigate the quality of multiple Chinese commercial dry red wine samples. A comprehensive method was developed by combining a high performance liquid chromatography-diode array detector-chemiluminescence (HPLC-DAD-CL) online hyphenated system with an HPLC-ESI-MS technique. Chromatographic and H2O2-scavenging active fingerprints of thirteen batches of different, commercially available Chinese dry red wine samples were obtained and analyzed. Twenty-five compounds, including eighteen antioxidants were identified and evaluated. The dominant and characteristic antioxidants in the samples were identified. The relationships between antioxidant potency and the cultivated variety of grape, producing area, cellaring period, and trade mark are also discussed. The results provide the feasibility for an integrated quality assessment strategy to be efficiently and objectively used in quality (especially antioxidant activity) assessment and identification of dry red wine.

Thirty-six (36 families participated in the study (17 with SSU and 19 with SNU; N = 144. Semi-structured interviews were conducted with 40 siblings (20 SNU and 20 SSU; 18-31 years old in order to qualitatively investigate the characteristics of the sibling relationship. The siblings were not identified with any psychopathology, according to SCL-90R. Moreover, we considered the family cohesion and adaptability, as identified by the FACES III (administered to the whole sample and the family constellation (including number of children, birth order, gender, family size, family structure, years of substance misuse and socioeconomic level. The results of the thematic analysis seem to support Furman and Buhrmester’s (1985 framework, in the context of SNU families. Nevertheless, when considering families with SSU the framework is enriched with a new axis: Loss/mourning. The substance misuse seems to provoke an overturn of the representation of the sibling relationship: the behavioral changes (i.e. disengagement of the sibling with drug use are experienced as a loss by the sibling non user, thus triggering the psychological process of ‘mourning’. Moreover, in these families, the sibling with no drug use seem to experience differential parenting, they feel neglected, angry and they take up a parental role towards the SSU, whom they experience as “sensitive” and “vulnerable”.

Hamaoka Unit No.1 (BWR 540 MWe) of Chubu Electric Power Company, Inc. had experienced fuel failures caused by fuel cladding corrosion at the cycle 11 in 1990. This cladding corrosion was considered to be caused by a combination of cladding material susceptibility to corrosion and anomalous reactor water quality. Based on the intensive investigations on the causes of anomalous reactor water quality, several countermeasures were proposed to improve the reactor water quality for the subsequent cycles operation. As the results of countermeasures, reactor water quality of Hamaoka Unit No.1 in the cycle 12 became much better than that of any other previous cycles and neither failure nor accelerated corrosion was found in the subsequent annual inspection. As one of the countermeasures for water quality improvement, an on-line ion chromatograph has been installed on Hamaoka Unit No.1 to reinforce reactor water quality monitoring, that has enabled us to identify ion species in reactor water and to evaluate reactor water behaviour in detail.

As one of the countermeasures for water quality improvement, an on-line ion chromatograph has been installed on Hamaoka Unit No.1 to reinforce reactor water quality monitoring, that has enabled us to identify ion species in reactor water and to evaluate reactor water behaviour in detail.

Full Text Available The main goal of VoIP services is to provide a reliable and high-quality voice transmission over packet networks. In order to prove the quality of VoIP transmission, several approaches were designed. In our approach, we are concerned about on-line monitoring of RTP and RTCP traffic. Based on these data, we are able to compute main VoIP quality metrics including jitter, delay, packet loss, and finally R-factor and MOS values. This technique of VoIP quality measuring can be directly incorporated into IPFIX monitoring framework where an IPFIX probe analyses RTP/RTCP packets, computes VoIP quality metrics, and adds these metrics into extended IPFIX flow records. Then, these extended data are stored in a central IPFIX monitoring system called collector where can be used for monitoring purposes. This paper presents a functional implementation of IPFIX plugin for VoIP quality measurement and compares the results with results obtained by other tools.

Numerous types of self-service technologies have prevailed due to innovations in network and information technology. To hospitals, patient intentions to continue to use the e-appointment system are crucial. Previous investigations discussed only the relationships between the technology readiness of users and their continuance intentions, and ignored the most important mediator, relationship quality. This study explored the relationships among technology readiness, relationship quality, and continuance intention. The research results demonstrated that both optimism and innovativeness significantly and positively influenced continuance intention through the mediating effect of relationship quality. However, discomfort and insecurity hid not significantly influence relationship quality or continuance intention. Finally, theoretical contributions, managerial implications and future research directions were discussed.

Patients often use the internet as a source of information about their condition and treatments. However, this information is unregulated and varies in quality. To evaluate the readability and quality of online information for pediatric and adult patients and caregivers regarding sclerotherapy for venous malformations. "Venous malformation sclerotherapy" was entered into Google, and results were reviewed until 20 sites that satisfied predefined inclusion criteria were identified. Scientific and non-patient-focused web pages were excluded. Readability was assessed using the Flesch Reading Ease Score and American Medical Association reading difficulty recommendations and quality was assessed using Journal of the American Medical Association standards and assessing if the site displayed HONcode (Health on the Net Code) certification. Assessment of the breadth of relevant information was made using a predefined checklist. Forty-nine search engine results were reviewed before 20 sites were identified for analysis. Average Flesch Reading Ease Score was 44 (range: 24.2-70.1), representing a "fairly difficult" reading level. None of the sites had a Flesch Reading Ease Score meeting the American Medical Association recommendation of 80-90. Only one site met all four Journal of the American Medical Association quality criteria (average: 2.1). None of the sites displayed a HONcode seal. The information most frequently found was: sclerotherapy is performed by radiologists, multiple treatments may be needed and surgery is an alternative treatment. Online information regarding sclerotherapy for venous malformations is heterogeneous in quality and breadth of information, and does not meet readability recommendations for patient information. Radiologists should be aware of and account for this when meeting patients.

A novel on-line database for capturing most of the information obtained during piloted handling qualities experiments (either flight or simulated) is described. The Hyperlinked Overview of Piloted Evaluations (HOPE) web application is based on an open-source object-oriented Web-based front end (Ruby-on-Rails) that can be used with a variety of back-end relational database engines. The hyperlinked, on-line data book approach allows an easily-traversed way of looking at a variety of collected data, including pilot ratings, pilot information, vehicle and configuration characteristics, test maneuvers, and individual flight test cards and repeat runs. It allows for on-line retrieval of pilot comments, both audio and transcribed, as well as time history data retrieval and video playback. Pilot questionnaires are recorded as are pilot biographies. Simple statistics are calculated for each selected group of pilot ratings, allowing multiple ways to aggregate the data set (by pilot, by task, or by vehicle configuration, for example). Any number of per-run or per-task metrics can be captured in the database. The entire run metrics dataset can be downloaded in comma-separated text for further analysis off-line. It is expected that this tool will be made available upon request

After completion of waste removal and chemical cleaning operations, Tanks 5-F and 6-F await final closure. The project will proceed with completing operational closure by stabilizing the tanks with grout. Savannah River Remediation's (SRR) experience with grouting Tanks 18-F and 19-F showed that slump-flow values were correlated with flow/spread inside these tanks. Less mounding was observed when using grouts with higher slump-flow. Therefore, SRNL was requested to evaluate the relationship between flowability and cured properties to determine whether the slump-flow maximum spread of Mix LP no. 8-16 could be increased from 28 inches to 30 inches without impacting the grout quality. A request was also made to evaluate increasing the drop height from 5 feet to 10 feet with the objective of enhancing the flow inside the tank by imparting more kinetic energy to the placement. Based on a review of the grout property data for Mix LP no. 8-16 collected from Tank 18-F and 19-F quality control samples, the upper limit for slump-flow measured per ASTM C 1611 can be increased from 28 to 30 inches without affecting grout quality. However, testing should be performed prior to increasing the drop height from 5 to 10 feet or observations should be made during initial filling operations to determine whether segregation occurs as a function of drop heights between 5 and 10 feet. Segregation will negatively impact grout quality. Additionally, increasing the delivery rate of grout into Tanks 5-F and 6-F by using a higher capacity concrete/grout pump will result in better grout spread/flow inside the tanks

Increasingly, consumers are accessing the Internet seeking health information. Consumers are also using online doctor review websites to help select their physician. Such websites tally numerical ratings and comments from past patients. To our knowledge, no study has previously analyzed whether doctors with positive online reputations on doctor review websites actually deliver higher quality of care typically associated with better clinical outcomes and better safety records. For a number of procedures, surgeons who perform more procedures have better clinical outcomes and safety records than those who perform fewer procedures. Our objective was to determine if surgeon volume, as a proxy for clinical outcomes and patient safety, correlates with online reputation. We investigated the numerical ratings and comments on 9 online review websites for high- and low-volume surgeons for three procedures: lumbar surgery, total knee replacement, and bariatric surgery. High-volume surgeons were randomly selected from the group within the highest quartile of claims submitted for reimbursement using the procedures' relevant current procedural terminology (CPT) codes. Low-volume surgeons were randomly selected from the lowest quartile of submitted claims for the procedures' relevant CPT codes. Claims were collated within the Normative Health Information Database, covering multiple payers for more than 25 million insured patients. Numerical ratings were found for the majority of physicians in our sample (547/600, 91.2%) and comments were found for 385/600 (64.2%) of the physicians. We found that high-volume (HV) surgeons could be differentiated from low-volume (LV) surgeons independently by analyzing: (1) the total number of numerical ratings per website (HV: mean = 5.85; LV: mean = 4.87, Pcustomer service (HV: mean = 0.24; LV: mean = 0.22, P=.52); and (3) proportion of scathing criticism/total comments about customer service (HV: mean = 0.19; LV: mean = 0.21, P=.48).

In this study, we investigated the clinical performance of an online dosimetry system (Mobius FX system, MFX) by 1) dosimetric plan verification using gamma passing rates and dose volume metrics and 2) error-detection capability evaluation by deliberately introduced machine error. Eighteen volumetric modulated arc therapy (VMAT) plans were studied. To evaluate the clinical performance of the MFX, we used gamma analysis and dose volume histogram (DVH) analysis. In addition, to evaluate the error-detection capability, we used gamma analysis and DVH analysis utilizing three types of deliberately introduced errors (Type 1: gantry angle-independent multi-leaf collimator (MLC) error, Type 2: gantry angle-dependent MLC error, and Type 3: gantry angle error). A dosimetric verification comparison of physical dosimetry system (Delt4PT) and online dosimetry system (MFX), gamma passing rates of the two dosimetry systems showed very good agreement with treatment planning system (TPS) calculation. For the average dose difference between the TPS calculation and the MFX measurement, most of the dose metrics showed good agreement within a tolerance of 3%. For the error-detection comparison of Delta4PT and MFX, the gamma passing rates of the two dosimetry systems did not meet the 90% acceptance criterion with the magnitude of error exceeding 2 mm and 1.5 ◦, respectively, for error plans of Types 1, 2, and 3. For delivery with all error types, the average dose difference of PTV due to error magnitude showed good agreement between calculated TPS and measured MFX within 1%. Overall, the results of the online dosimetry system showed very good agreement with those of the physical dosimetry system. Our results suggest that a log file-based online dosimetry system is a very suitable verification tool for accurate and efficient clinical routines for patient-specific quality assurance (QA).

In-person conjoint treatments for relationship distress are effective at increasing relationship satisfaction, and newly developed online programs are showing promising results. However, couples reporting even low levels intimate partner violence (IPV) are traditionally excluded from these interventions. To improve the availability of couple-based treatment for couples with IPV, the present study sought to determine whether associations with IPV found in community samples generalized to couples seeking help for their relationship and whether web-based interventions for relationship distressed worked equally well for couples with IPV. In the first aim, in a sample of 2,797 individuals who were seeking online help for their relationship, the levels and correlates of both low-intensity and clinically significant IPV largely matched what is found in community samples. In the second aim, in a sample of 300 couples who were randomly assigned to a web-based intervention or a waitlist control group, low-impact IPV did not moderate the effects of the intervention for relationship distress. Therefore, web-based interventions may be an effective (and easily accessible) intervention for relationship distress for couples with low-intensity IPV. © 2017 Family Process Institute.

Little is known about the relationships between eating competence (intra-individual approach to eating and food-related attitudes and behaviors that entrain positive bio-psychosocial outcomes) and sleep behaviors and quality in college students, a high-risk group for poor eating habits, weight gain, and inadequate sleep. Thus, data from full-time college students (N=1035; 82% White; 61% female) aged 18-24 years from 5 U.S. universities were obtained from online questionnaires (eating competence (ecSI), Pittsburg Sleep Quality Index (PSQI), physical activity, demographics) and physical assessments (measured height, weight), to explore sleep behavior and quality between eating-competent (EC; ecSI score≥32) and non-EC groups (ecSIsleep quality (67% vs. 57% in non-EC, p=0.001), sleep duration of ≥7 h nightly (58% vs. 50% in non-EC, p=0.007), and infrequent daytime dysfunction (72% vs. 65% in non-EC, p=0.02). When ecSI scores were grouped as tertiles, those in the highest tertile reported a higher prevalence of no sleep disturbances (7% vs. 2% in the lowest ecSI tertile, p=0.006) and lower prevalence of sleep medication use (10% vs. 15% in the lowest ecSI tertile, p=0.04). Results suggest that competent eaters are more likely to have better overall sleep quality and fewer sleep-related issuescompared to less competent eaters. These findings may inform future longitudinal studies, and health promotion and weight management interventions for young adults. Copyright © 2015 Elsevier Ltd. All rights reserved.
Full Text Available A large number of banks let people be more free in choosing the best bank for their needs. People can freely switch from one bank to another which makes the loyalty level of bank customers decrease, even though the efforts and cost spent for maintaining the customers is cheaper than the efforts and cost spent on getting new customers. Relationship is one of the answers to the problem, relationship marketing is a marketing principle which emphasizes and takes effort in maintaining good long term relationship with customers. This research aims to, analyze the influence competence, communication, and conflict handling towards relationship quality, mediated by relationship quality, and towards customer loyalty.

To assess the quality of information provided to consumers by websites marketing medical home diagnostic tests. A cross-sectional analysis of a database developed from searching targeted websites. Data sources were websites written in English which marketed medical home diagnostic tests. A meta-search engine was used to identify the first 20 citations for each type of home diagnostic medical test. Relevant websites limited to those written in English were reviewed independently and in triplicate, with disputes resolved by two further reviewers. Information on the quality of these sites was extracted using a pre-piloted performer. 168 websites were suitable for inclusion in the review. The quality of these sites showed marked variation. Only 24 of 168 (14.2%) complied with at least three-quarters of the quality items and just over half (95 of 168, 56.5%) reported official approval or certification of the test. Information on accuracy of the test marketed was reported by 87 of 168 (51.7%) websites, with 15 of 168 (8.9%) providing a scientific reference. Instructions for use of the product were found in 97 of 168 (57.9%). However, the course of action to be taken after obtaining the test result was stated in only 63 of 168 (37.5%) for a positive result and 43 of 168 (25.5%) for a negative result. The quality of information posted on commercial websites marketing home tests online is unsatisfactory and potentially misleading for consumers.

Patients seeking information and advice on treatment of scaphoid fractures unknowingly confront longstanding medical controversies surrounding the management of this condition. However, there are no studies specifically looking into the quality and reliability of online information on scaphoid fractures. We identified 44 unique websites for evaluation using the term "scaphoid fractures". The websites were categorized by type and assessed using the DISCERN score, the Journal of the American Medical Association (JAMA) benchmark criteria and the Health on the net (HON) code. The majority of websites were commercial (n = 13) followed by academic (n = 12). Only seven of the websites were HON certified. The mean DISCERN score was 43.8. Only 4 websites scored 63 or above representing excellent quality with minimal shortcomings but 13 websites scored 38 or below representing poor or very poor quality. The mean JAMA benchmark criteria score was 2.2. The Governmental and Non-Profit Organizations category websites had the highest mean JAMA benchmark score. The websites that displayed the HON-code seal had higher mean DISCERN scores and higher mean JAMA benchmark scores compared to websites that did not display the seal. Good quality health information is certainly available on the Internet. However, it is not possible to predict with certainty which sites are of higher quality. We suggest clinicians should have a responsibility to educate their patients regarding the unregulated nature of medical information on the internet and proactively provide patients with educational resources and thus help them make smart and informed decisions.

This study investigates the mediating role of identity confusion and materialism in the relationship between social networking site (SNS) excessive usage and online compulsive buying among young adults. A total of 501 SNS users aged 17 to 23 years (M = 19.68, SD = 1.65) completed an online survey questionnaire. A serial multiple mediator model was developed and hypotheses were tested using structural equation modeling. The results showed that excessive young adult SNS users had a higher tendency toward compulsive buying online. This was partly because they experienced higher identity confusion and developed higher levels of materialism. Targeted psychological interventions seeking to gradually increase identity clarity to buffer the detrimental effects of SNS usage and identity confusion in young adults are suggested.

Breast cancer patients commonly use the internet as an information resource. Our objective was to evaluate the quality of online information available to support patients facing a decision for breast surgery. Breast cancer surgery-related queries were performed (Google and Bing), and reviewed for content pertinent to breast cancer surgery. The DISCERN instrument was used to evaluate websites' structural components that influence publication reliability and ability of information to support treatment decision-making. Scores of 4/5 were considered "good." 45 unique websites were identified. Websites satisfied a median 5/9 content questions. Commonly omitted topics included: having a choice between breast conservation and mastectomy (67%) and potential for 2nd surgery to obtain negative margins after breast conservation (60%). Websites had a median DISCERN score of 2.9 (range 2.0-4.5). Websites achieved higher scores on structural criteria (median 3.6 [2.1-4.7]), with 24% rated as "good." Scores on supporting decision-making questions were lower (2.6 [1.3-4.4]), with only 7% scoring "good." Although numerous breast cancer-related websites exist, most do a poor job providing women with essential information necessary to actively participate in decision-making for breast cancer surgery. Providing easily- accessible, high-quality online information has the potential to significantly improve patients' experiences with decision-making. © 2015 Wiley Periodicals, Inc.

Water temperature, dissolved oxygen, and concentrations of salts in surface water bodies can be affected by the natural environment, local human activities such as surface and ground water withdrawals, land use, and energy extraction, and variability and long-term trends in atmospheric conditions including temperature and precipitation. Here, we quantify the relationship between 121 indicators of mean and extreme temperature and precipitation and 24 water quality parameters in 57 Texas reservoirs using observational data records covering the period 1960 to 2010. We find that water temperature, dissolved oxygen, pH, specific conductance, chloride, sulfate, and phosphorus all show consistent correlations with atmospheric predictors, including high and low temperature extremes, dry days, heavy precipitation events, and mean temperature and precipitation over time scales ranging from one week to two years. Based on this analysis and published future projections for this region, we expect climate change to increase water temperatures, decrease dissolved oxygen levels, decrease pH, increase specific conductance, and increase levels of sulfate, chloride in Texas reservoirs. Over decadal time scales, this may affect aquatic ecosystems in the reservoirs, including altering the risk of conditions conducive to algae occurrence, as well as affecting the quality of water available for human consumption and recreation.

Basic audio quality (BAQ) is a well-known perceptual attribute, which is rated in various listening test methods to measure the performance of audio systems. Unfortunately, when it comes to purchasing audio systems, BAQ might not have a significant influence on the customers' buying decisions since other factors, like brand loyalty, might be more important. In contrast to BAQ, overall listening experience (OLE) is an affective attribute which incorporates all aspects that are important to an individual assessor, including his or her preference for music genre and audio quality. In this work, the relationship between BAQ and OLE is investigated in more detail. To this end, an experiment was carried out, in which participants rated the BAQ and the OLE of music excerpts with different timbral and spatial degradations. In a between-group-design procedure, participants were assigned into two groups, in each of which a different set of stimuli was rated. The results indicate that rating of both attributes, BAQ and OLE, leads to similar rankings, even if a different set of stimuli is rated. In contrast to the BAQ ratings, which were more influenced by timbral than spatial degradations, the OLE ratings were almost equally influenced by timbral and spatial degradations.

Enterococci are used to assess the risk of negative human health impacts from recreational waters. Studies have shown sustained populations of enterococci within sediments of beaches but comprehensive surveys of multiple tidal zones on beaches in a regional area and their relationship to beach management decisions are limited. We sampled three tidal zones on eight South Florida beaches in Miami-Dade and Broward counties and found that enterococci were ubiquitous within South Florida beach sands although their levels varied greatly both among the beaches and between the supratidal, intertidal and subtidal zones. The supratidal sands consistently had significantly higher (p sand) than the other two zones. Levels of enterococci within the subtidal sand correlated with the average level of enterococci in the water (CFU/100mL) for the season during which samples were collected (r(s) = 0.73). The average sand enterococci content over all the zones on each beach correlated with the average water enterococci levels of the year prior to sand samplings (r(s) = 0.64) as well as the average water enterococci levels for the month after sand samplings (r(s) = 0.54). Results indicate a connection between levels of enterococci in beach water and sands throughout South Florida's beaches and suggest that the sands are one of the predominant reservoirs of enterococci impacting beach water quality. As a result, beaches with lower levels of enterococci in the sand had fewer exceedences relative to beaches with higher levels of sand enterococci. More research should focus on evaluating beach sand quality as a means to predict and regulate marine recreational water quality. Copyright © 2011 Elsevier Ltd. All rights reserved.

Polymeric membrane has been widely used for the treatment of drinking water in China, and the total treating capacity has reached up to 3.8 million m 3 /d. However, the membrane breakage found in the membrane modules in many water treatment plants resulted in an increase in turbidity and bacterial amount in the membrane permeate. In this study, a membrane module running for 3 years in a full-scale application was examined in terms of the breaking positions and the numbers of the broken fibers. It was found that most of the breaking positions were mainly on the outlet side of the module and that the distance from these points to the outlet was about 1/10-2/10 length of the membrane module. The lab-scale tests showed that the increase of the numbers of the breaking fibers in the membrane module (the breaking fibers were from 1 to 4 of 75 fibers) resulted in the increase in turbidity, particle count and the amount of total bacteria and coliform bacteria. Meanwhile, the water quality after the filtration with broken membrane fibers was similar to the quality of the raw water, which indicated that once the membrane fiber breakage occurred in the membrane module, the quality of drinking water after membrane filtration was significantly affected. Furthermore, the breaking position closer to the outlet side of the membrane module exposed much higher microbiological risk than those in the middle or near the bottom side. A pilot scale test was conducted by using a membrane module with 6600 fibers, and the effect of the membrane breakage (1-4 broken fibers) on water quality was also investigated. The results indicated that periodical backwashing caused drastic fluctuation of turbidity, particle count and the bacterial amount in the permeate water, which might be due to the washing force and self-blocking action inside the hollow fibers. Moreover, there is a good quantitative relationship (R 2 = 0.945) between particle count and the bacterial amount, which indicated that an

To critically evaluate the quality, accuracy, and readability of readily available Internet patient resources for platelet-rich plasma (PRP) as a treatment modality for musculoskeletal injuries. Using the 3 most commonly used Internet search engines (Google, Bing, Yahoo), the search term "platelet rich plasma" was entered, and the first 50 websites from each search were reviewed. The website's affiliation was identified. Quality was evaluated using 25-point criteria based on guidelines published by the American Academy of Orthopaedic Surgeons, and accuracy was assessed with a previously described 12-point grading system by 3 reviewers independently. Readability was evaluated using the Flesch-Kincaid (FK) grade score. A total of 46 unique websites were identified and evaluated. The average quality and accuracy was 9.4 ± 3.4 (maximum 25) and 7.9 ± 2.3 (maximum 12), respectively. The average FK grade level was 12.6 ± 2.4, which is several grades higher than the recommended eighth-grade level for patient education material. Ninety-one percent (42/46) of websites were authored by physicians, and 9% (4/46) contained commercial bias. Mean quality was significantly greater in websites authored by health care providers (9.8 ± 3.1 vs 5.9 ± 4.7, P = .029) and in websites without commercial bias (9.9 ± 3.1 vs 4.5 ± 3.2, P = .002). Mean accuracy was significantly lower in websites authored by health care providers (7.6 ± 2.2 vs 11.0 ± 1.2, P = .004). Only 24% (11/46) reported that PRP remains an investigational treatment. The accuracy and quality of online patient resources for PRP are poor, and the information overestimates the reading ability of the general population. Websites authored by health care providers had higher quality but lower accuracy. Additionally, the majority of websites do not identify PRP as an experimental treatment, which may fail to provide appropriate patient understanding and expectations. Physicians should educate patients that many online

With the growing opioid crisis in the United States, there has been a push to reduce the utilization of opioids in favor of multimodal analgesia options. The purpose of this study was to evaluate the quality of online resources that patients may use to learn about pain control after total knee arthroplasty (TKA). We identified websites using a combination of search terms about TKA and pain control. A novel grading rubric was created with 25 maximum points, consisting of items that were deemed important for patients to know about the subject. Three authors then independently graded websites and the results averaged. Flesch-Kinkaid reading level was also evaluated. After identifying 166 unique websites, 32 met final inclusion criteria. The overall scores were low-4.7 of 25 total points (18.8%), written at an average 10th grade level. Subgroup scores were 50% for route of administration, 40% for types of analgesia, 23% for opioid-specific items, and 30% for general guidance. Only about half discussed the risks of opioid dependency. The top 3 website total scores ranged from 10.7-12.5 of 25 points. There is a paucity of online information for TKA patients to read about pain control. Most websites provide limited educational content, particularly about opioids. Higher quality information is needed to help patients make decisions with their physicians and to help combat the opioid epidemic. Given the lack of quality information available, there is an opportunity for subspecialty organizations to take a leadership role in such efforts. Copyright © 2017 Elsevier Inc. All rights reserved.

The article explores the different types of therapeutic relationship that can evolve both on- and offline, thanks to the use of tools, such as software and applications, which enable therapists and patients contact outside of the traditional setting. Given the premise that it is practically impossible today to maintain a relationship without the use of internet and telephones, it becomes necessary to question the ways in which the online space can become a useful extension of the therapeutic setting. The authors, starting from a consideration regarding the specificity of the online therapeutic relationship, analyze the best ways to use text and email messaging with patients. Furthermore, specific interactions via group chats are presented, for example, to coordinate a therapeutic team involving several professionals. Further, video chat settings are discussed through a clinical case presentation. Lastly, the therapist's management of social networks is debated, underscoring the importance for the therapists that his or her online identity be consistent with the offline image which patients are introduced to in the traditional setting of the therapy room.

Sleep is one of the most basic human requirements. This research aims at determining the status of sleep quality and its relationship with quality of life among high-risk pregnant women in Tabriz, Iran, in 2015. This research was a sectional study done on 364 qualified women in 28-36 weeks of pregnancy suffering from mild preeclampsia and gestational diabetes. The sampling was done as convenience. Personal-social-midwifery questionnaire, Pittsburg sleep quality, and quality of life in pregnancy (QOL-ORAV) were used for gathering data. Multivariate linear regression model was used for determining the relationship between sleep quality and its subsets with quality of life and controlling confounders. In the current study, the prevalence of sleep disturbance was 96.4%. Mean (SD) of the total score of sleep quality was 10.1 (4.1) and the total score of quality of life was 61.7 (17.3). According to Pearson's correlation test, there was statistically significant relationship between quality of life and sleep quality and all its subsets except sleep duration and use of sleep medication (p quality of life. The findings of current research show that sleep quality is low among high-risk pregnant women and quality of life is medium. So, it is necessary that required training is given by health cares for improving sleep quality and quality of life to mothers.

Firstly, this study provides a real-time implementation of online dose reconstruction for tracked volumetric arc therapy (VMAT). Secondly, this study describes a novel offline quality assurance tool, based on commercial dose calculation algorithms. Online dose reconstruction for VMAT is a computationally challenging task in terms of computer memory usage and calculation speed. To potentially reduce the amount of memory used, we analyzed the impact of beam angle sampling for dose calculation on the accuracy of the dose distribution. To establish the performance of the method, we planned two single-arc VMAT prostate stereotactic body radiation therapy cases for delivery with dynamic MLC tracking. For quality assurance of our online dose reconstruction method we have also developed a stand-alone offline dose reconstruction tool, which utilizes the RayStation treatment planning system to calculate dose. For the online reconstructed dose distributions of the tracked deliveries, we could establish strong resemblance for 72 and 36 beam co-planar equidistant beam samples with less than 1.2% deviation for the assessed dose-volume indicators (clinical target volume D98 and D2, and rectum D2). We could achieve average runtimes of 28-31 ms per reported MLC aperture for both dose computation and accumulation, meeting our real-time requirement. To cross-validate the offline tool, we have compared the planned dose to the offline reconstructed dose for static deliveries and found excellent agreement (3%/3 mm global gamma passing rates of 99.8%-100%). Being able to reconstruct dose during delivery enables online quality assurance and online replanning strategies for VMAT. The offline quality assurance tool provides the means to validate novel online dose reconstruction applications using a commercial dose calculation engine. © 2017 The Authors.

Full Text Available Abstract Background There are caregivers who see their quality of life (QoL impaired due to the demands of their caregiving tasks, while others manage to adapt and overcome the crises successfully. The influence of the family function in the main caregiver's situation has not been the subject of much evaluation. The aim of this study is to analyse the relationship between the functionality of the family and the QoL of caregivers of dependent relatives. Methods We conducted a cross-sectional study including 153 caregivers. Setting: Two health centers in the city of Salamanca(Spain. Caregiver variables analysed: demographic characteristics, care recipient features; family functionality (Family APGAR-Q and QoL (Ruiz-Baca-Q perceived by the caregiver. Five multiple regressions are performed considering global QoL and each of the four QoL dimensions as dependent variables. The Canonical Correspondence Analysis (CCA was used to study the influence of the family function questionnaire on QoL. Results Family function is the only one of the variables evaluated that presented an association both with global QoL and with each of the four individual dimensions (p Conclusion We find an association between family functionality and the caregiver's QoL. This relation holds for both the global measure of QoL and each of its four individual dimensions.

The relationships among napping and sleep quality, fatigue, and quality of life (QOL) in cancer patients are not clearly understood. The aim of the study was to determine whether daytime napping is associated with nighttime sleep, fatigue, and QOL in cancer patients. In total, 187 cancer patients were recruited. Daytime napping, nighttime self-reported sleep, fatigue, and QOL were assessed using a questionnaire. Objective sleep parameters were collected using a wrist actigraph. According to waking-after-sleep-onset measurements, patients who napped during the day experienced poorer nighttime sleep than did patients who did not (t = -2.44, P = .02). Daytime napping duration was significantly negatively correlated with QOL. Patients who napped after 4 PM had poorer sleep quality (t = -1.93, P = .05) and a poorer Short-Form Health Survey mental component score (t = 2.06, P = .04) than did patients who did not. Fatigue, daytime napping duration, and sleep quality were significant predictors of the mental component score and physical component score, accounting for 45.7% and 39.3% of the variance, respectively. Daytime napping duration was negatively associated with QOL. Napping should be avoided after 4 PM. Daytime napping affects the QOL of cancer patients. Future research can determine the role of napping in the sleep hygiene of cancer patients.

Abstract Some researchers believe that online gaming spaces can be socially accommodating environments for socially inhibited individuals, such as the socially inept, socially anxious, or shy. While previous research has examined, and found, significant links between these populations and online video game play, it remains unknown to what extent these spaces are contributing to tangible social benefits for the socially inhibited. The current study addresses this question by evaluating the link between gaming-related friendships and shyness, as quantified by emotional sensitivity. Drawing from a representative sample of German game players, the results indicate that emotionally sensitive players are using online gaming spaces differently from their less emotionally sensitive counterparts and reporting tangible differences in their in-game friendship networks. This suggests that online games hold the potential to be socially advantageous for shy individuals by allowing them to overcome their traditional social difficulties and generate new friendships as well as strengthen old ones.

Full Text Available Customer service is crucially important for online shopping platforms (OSPs such as eBay and Taobao. Based on the well-established service quality instruments and the scenario of the specific case on Taobao, this paper focuses on exploring the service quality of an OSP with an aim of revealing customer perceptions of the service quality associated with the provided functions and investigating their impacts on customer loyalty. By an empirical study, this paper finds that the “fulfillment and responsiveness” function is significantly related to the customer loyalty. Further analytical study is conducted to reveal that the optimal service level on the “fulfillment and responsiveness” function for the risk averse OSP uniquely exists. Moreover, the analytical results prove that (i if the customer loyalty is more positively correlated to the service level, it will lead to a larger optimal service level, and (ii the optimal service level is independent of the profit target, the source of uncertainty, and the risk preference of the OSP.

The Protein Movie Generator (PMG) is an online service able to generate high-quality pictures and animations for which one can then define simple storyboards. The PMG can therefore efficiently illustrate concepts such as molecular motion or formation/dissociation of complexes. Emphasis is put on the simplicity of animation generation. Rendering is achieved using Dino coupled to POV-Ray. In order to produce highly informative images, the PMG includes capabilities of using different molecular representations at the same time to highlight particular molecular features. Moreover, sophisticated rendering concepts including scene definition, as well as modeling light and materials are available. The PMG accepts Protein Data Bank (PDB) files as input, which may include series of models or molecular dynamics trajectories and produces images or movies under various formats. PMG can be accessed at http://bioserv.rpbs.jussieu.fr/PMG.html. PMID:17478496
Full Text Available Advice provided by financial planners has the potential to impact the financial and emotional well being ofclients. Despite the outcomes of quality financial planning relationships, there is little direct evidence tosupport the importance of ‘relationship quality’ in financial planning. Previous research has emphasised theimportance of relationship quality in psychology, nursing, and business settings. This research investigatesdeterminants of client-professional relationship quality in financial planning, measured in a survey of clientsand financial planners regarding relationship factors of trust, engagement, empowerment, ownership, clientactivity and commitment. Ratings for relationship dimensions were compared between clients and financialplanners, with financial planners found to overestimate their clients’ levels of trust and commitment andunderestimate their client’s levels of empowerment. The relationship dimension of ‘trust’ was found to becritical for client-professional relationship quality.

Objective To assess the quality of information provided to consumers by websites marketing medical home diagnostic tests. Design A cross-sectional analysis of a database developed from searching targeted websites. Setting Data sources were websites written in English which marketed medical home diagnostic tests. Main outcome measures A meta-search engine was used to identify the first 20 citations for each type of home diagnostic medical test. Relevant websites limited to those written in English were reviewed independently and in triplicate, with disputes resolved by two further reviewers. Information on the quality of these sites was extracted using a pre-piloted performer. Results 168 websites were suitable for inclusion in the review. The quality of these sites showed marked variation. Only 24 of 168 (14.2%) complied with at least three-quarters of the quality items and just over half (95 of 168, 56.5%) reported official approval or certification of the test. Information on accuracy of the test marketed was reported by 87 of 168 (51.7%) websites, with 15 of 168 (8.9%) providing a scientific reference. Instructions for use of the product were found in 97 of 168 (57.9%). However, the course of action to be taken after obtaining the test result was stated in only 63 of 168 (37.5%) for a positive result and 43 of 168 (25.5%) for a negative result. Conclusions The quality of information posted on commercial websites marketing home tests online is unsatisfactory and potentially misleading for consumers. PMID:18263912

Recently, online health expert question-answering (HQA) services (systems) have attracted more and more health consumers to ask health-related questions everywhere at any time due to the convenience and effectiveness. However, the quality of answers in existing HQA systems varies in different situations. It is significant to provide effective tools to automatically determine the quality of the answers. Two main characteristics in HQA systems raise the difficulties of classification: (1) physicians' answers in an HQA system are usually written in short text, which yields the data sparsity issue; (2) HQA systems apply the quality control mechanism, which refrains the wisdom of crowd. The important information, such as the best answer and the number of users' votes, is missing. To tackle these issues, we prepare the first HQA research data set labeled by three medical experts in 90days and formulate the problem of predicting the quality of answers in the system as a classification task. We not only incorporate the standard textual feature of answers, but also introduce a set of unique non-textual features, i.e., the popular used surface linguistic features and the novel social features, from other modalities. A multimodal deep belief network (DBN)-based learning framework is then proposed to learn the high-level hidden semantic representations of answers from both textual features and non-textual features while the learned joint representation is fed into popular classifiers to determine the quality of answers. Finally, we conduct extensive experiments to demonstrate the effectiveness of including the non-textual features and the proposed multimodal deep learning framework. Copyright © 2017 Elsevier Inc.

Health literacy among caregivers of food allergic individuals (FAIs) is poorly described, as are the information sources sought regarding food allergy. To assess the association among health literacy, trust in online sources of information, and food allergy quality of life (QoL) and self-efficacy. An online survey was administered to caregivers of FAIs assessing health literacy (Newest Vital Sign [NVS] and the eHeals Internet health literacy index), trust in online information (Hargittai Internet credibility index and Annenberg National Health Communication Survey [ANHCS]), QoL (Food Allergy Quality of Life Parental Burden), and self-efficacy (Food Allergy Self-Efficacy Questionnaire [FASEQ]). Among 1562 respondents, 94.6% (NVS) and 61.1% (eHeals) had good health literacy, and 58% had high levels of trust in online information (both indexes). The NVS correlated poorly with the eHeals and Hargittai indexes. Hargittai and eHeals scores were moderately correlated (r = 0.37, P information (both indexes), worsening FASEQ score, blog readership, advocacy group membership, caring for multiple FAIs, and having milk or egg allergy were associated with worse FAQL-PB scores. In this sample, health literacy and trust in online information sources were high, with high trust in online information sources negatively associated with QoL. Advocacy group membership had an independent negative association with QoL. Copyright © 2016 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.

Passion represents one of the factors involved in online video gaming. However, it remains unclear how passion affects the way gamers are involved in massively multiplayer online role-playing games (MMORPGs). The objective of the present study was to analyze the relationships between passions and motivations for online game playing. A total of 410 MMORPG players completed an online questionnaire including motives for gaming and the Passion Scale. Results indicated that passionate gamers were interested in relating with others through the game and exhibited a high degree of interest in discovery of the game, gaining leadership and prestige but little interest in escape from reality. However, some differences were observed with respect to the role of the two types of passion in the different types of motivation. Specifically, harmonious passion (HP) predicted higher levels of exploration, socialization, and achievement, in that order, while obsessive passion (OP) predicted higher levels of dissociation, achievement, and socialization. The present findings suggest that HP and OP predict different ways of engaging in MMORPGs and confirm that passion is a useful construct to help understand different motivational patterns demonstrated by MMORPG players.

Although the Internet is commonly used by lesbian, gay, bisexual, and transgender (LGBT) youth to explore aspects of sexual health, little is known about how this usage relates to offline explorations and experiences. This study used a mixed-methods approach to investigate the interplay between online and offline explorations of multiple dimensions of sexual health, which include sexually transmitted infections, sexual identities, romantic relationships, and sexual behaviors. A diverse community sample of 32 LGBT youth (ages 16-24) completed semi-structured interviews, which were transcribed and then qualitatively coded to identify themes. Results indicated that, although many participants evaluated online sexual health resources with caution, they frequently used the Internet to compensate for perceived limitations in offline resources and relationships. Some participants turned to the Internet to find friends and romantic partners, citing the relative difficulty of establishing offline contact with LGBT peers. Further, participants perceived the Internet as an efficient way to discover offline LGBT events and services relevant to sexual health. These results suggest that LGBT youth are motivated to fill gaps in their offline sexual health resources (e.g., books and personal communications) with online information. The Internet is a setting that can be harnessed to provide support for the successful development of sexual health.

The transgender population is disproportionally affected by health disparities related to access to care. In many communities, transgender specialists are geographically distant and locally available medical professionals may be unfamiliar with unique needs of transgender patients. As a result, use of Internet resources for information about gender affirming surgery is particularly important. This study simulates a patient search for online educational material about gender affirming surgery and evaluates the accessibility, readability, and quality of the information. An Internet search for the term "transgender surgery" was performed, and the first 10 relevant hits were identified. Readability was assessed using 10 established tests: Coleman-Liau, Flesch-Kincaid, FORCAST, Fry, Gunning Fog, New Dale-Chall, New Fog Count, Raygor Estimate, Simple Measure of Gobbledygook, and Flesch Reading Ease. Quality was assessed using Journal of the American Medical Association criteria and the DISCERN instrument. Review of 69 results was required to identify 10 sites with relevant patient information. There were 97 articles collected; overall mean reading level was 14.7. Individual Web site reading levels ranged from 12.0 to 17.5. All articles and Web sites exceeded the recommended sixth grade level. Quality ranged from 0 to 4 (Journal of the American Medical Association) and 35 to 79 (DISCERN) across Web sites. Web sites with relevant patient information about gender affirming surgery were difficult to identify from search results. The content of these sites universally exceeded the recommended reading level. A wide range of Web site quality was noted, and this may further complicate successful navigation. Barriers in access to appropriately written patient information on the Internet may contribute to disparities in referral, involvement, satisfaction, and outcomes. Copyright © 2017 Elsevier Inc.

Full Text Available Objective: Mounting evidence suggests a putative link between overuse of digital media and easily accessible drugs such as alcohol and nicotine. Method: We assessed Internet addiction tendencies in a sample of N=1,362 male players of online first-person-shooter-video games. We used Young’s 20-item Internet addiction test (IAT. We also asked participants about their smoking status and alcohol consumption. Results: No significant differences were observed on the IAT between smokers, non-smokers and ex-smokers. However, in line with the majority of the literature, the results yielded support for a link between Internet addiction and alcohol consumption. Of importance, this correlation was influenced by the current smoking status. This relationship was especially pronounced for the group of ex-smokers. Conclusions: It is possible that after quitting smoking, drinking habits and online activities may be used to compensate for nicotine abstinence.

Prisons worldwide operate under crowded conditions, in which prisoners are forced to share a cell. Few studies have looked at the relationship between cell sharing and the quality of prison life in Europe. This study aims to fill this gap with a multilevel analysis on the link between cell sharing and quality of prison life, using results from a Dutch prisoner survey. Findings show that cell sharing is associated with lower perceived prison quality, which is partially mediated by reduced quality of staff-prisoner relationships. Cell sharing thus undermines the Dutch penological philosophy, which considers staff-prisoner relationships to be at the heart of prisoner treatment and rehabilitation. It is recommended that prisoners are held in single rather than double cells. © The Author(s) 2014.

The distribution of drinking water generates soft deposits and biofilms in the pipelines of distribution systems. Disturbances in water distribution can detach these deposits and biofilms and thus deteriorate the water quality. We studied the effects of simulated pressure shocks on the water quality with online analysers. The study was conducted with copper and composite plastic pipelines in a pilot distribution system. The online data gathered during the study was evaluated with Self-Organising Map (SOM) and Sammon's mapping, which are useful methods in exploring large amounts of multivariate data. The objective was to test the usefulness of these methods in pinpointing the abnormal water quality changes in the online data. The pressure shocks increased temporarily the number of particles, turbidity and electrical conductivity. SOM and Sammon's mapping were able to separate these situations from the normal data and thus make those visible. Therefore these methods make it possible to detect abrupt changes in water quality and thus to react rapidly to any disturbances in the system. These methods are useful in developing alert systems and predictive applications connected to online monitoring.

The objective of the study was to evaluate practices in Spanish hospitals after intrauterine death in terms of medical/ technical care and bereavement support care. A cross-sectional descriptive study using an online self-completion questionnaire. The population was defined as women who had experienced an intrauterine fetal death between sixteen weeks and birth, either through spontaneous late miscarriage/stillbirth or termination of pregnancy for medical reasons. Respondents were recruited through an online advertisement on a stillbirth charity website and social media. The analysis used Pearson's chi-squared (p ≤ 0.05) test of independence to cross-analyse for associations between objective measures of care quality and independent variables. Responses from 796 women were analysed. Half of the women (52.9%) had postmortem contact with their baby. 30.4% left the hospital with a least one linking object or a photograph. In 35.8% of cases parents weren't given any option to recover the body/remains. 22.9% of births ≥26 weeks gestation were by caesarean, with a significant (p < 0.001) difference between public hospitals (16.8%) and private hospitals (41.5%). 29.3% of respondents were not accompanied during the delivery. 48.0% of respondents recalled being administered sedatives at least once during the hospital stay. The autopsy rate in stillbirth cases (≥ 20 weeks) was 70.5% and 44.4% in cases of termination of pregnancy (all gestational ages). Consistent significant (p < 0.05) differences in care practices were found based on gestational age and type of hospital (public or private), but not to other variables related to socio-demographics, pregnancy history or details of the loss/death. Intrauterine deaths at earlier gestational ages received poorer quality care. Supportive healthcare following intrauterine death is important to women's experiences in the hospital and beneficial to the grief process. Many care practices that are standard in

Development, initial validation and reliability testing of a shortened version of a web-based questionnaire instrument to measure generic health-related quality of life in companion dogs, to facilitate smartphone and online use. The original 46 items were reduced using expert judgment and factor analysis. Items were removed on the basis of item loadings and communalities on factors identified through factor analysis of responses from owners of healthy and unwell dogs, intrafactor item correlations, readability of items in the UK, USA and Australia and ability of individual items to discriminate between healthy and unwell dogs. Validity was assessed through factor analysis and a field trial using a "known groups" approach. Test-retest reliability was assessed using intraclass correlation coefficients. The new instrument comprises 22 items, each of which was rated by dog owners using a 7-point Likert scale. Factor analysis revealed a structure with four health-related quality of life domains (energetic/enthusiastic, happy/content, active/comfortable, and calm/relaxed) accounting for 72% of the variability in the data compared with 64% for the original instrument. The field test involving 153 healthy and unwell dogs demonstrated good discriminative properties and high intraclass correlation coefficients. The 22-item shortened form is superior to the original instrument and can be accessed via a mobile phone app. This is likely to increase the acceptability to dog owners as a routine wellness measure in health care packages and as a therapeutic monitoring tool. © 2017 British Small Animal Veterinary Association.

Accordingly, instructors should continuously evaluate the effectiveness of such online materials. This paper sets forth the author's initial attempts to analyze a business course…
From 2009 to 2010, online college enrollment grew by one million students (Allen & Seaman, 2010.) To address this growth, the number of online courses and programs has increased as well (Windes & Lesht, 2014). Online programs and courses that are well developed can provide a rewarding educational experience for students. However, the…

We have integrated an imaging thermographic sensor into commercial welding optics for observation of the weld zone. Key element of the sensor is an InGaAs-camera that detects the thermal radiation of the welding process in the wavelength range of 1,200 to 1,700 nm. This is well suited to record images of the keyhole, the melt pool and the thermal trace. The sensor was integrated to the welding heads for on-axis observation to minimize the interfering contour to ensure easy adaption to industrial processes. The welding heads used were established industrial-grade TRUMPF optics: a BEO fixed optics with 280 mm focal length, or a TRUMPF PFO-3D scanner optics with 450 mm focal length. We used a TRUMPF TruDisk 16002 16kW-thin disk laser that transmits its power through a 200 μm core diameter light cable. The images were recorded and features of the various process zones were evaluated by image processing. It turns out that almost all weld faults can be clearly detected in the NIR images. Quantitative features like the dimension of the melt pool and the thermal trace can be derived from the captured images. They are correlated to process input parameters as well as to process results. In contrast to observation in the visible spectrum the NIR camera records the melt pool without auxiliary illumination. As an unrivaled attribute of the NIR sensor it supports an online heat flow thermography of the seam and allows identifying missing fusion ("false friends") of lap joints virtually during the welding process. Automated weld fault detection and documentation is possible by online image processing which sets the basis for comprehensive data documentation for quality assurance and traceability.

Quality improvement (QI) is becoming an important focal point for health systems. There is increasing interest among health system stakeholders to learn from and share experiences on the use of QI methods and approaches in their work. Yet there are few easily accessible, online repositories dedicated to documenting QI activity. We conducted a scoping review of publicly available, web-based QI repositories to (i) identify current approaches to sharing information on QI practices; (ii) categorise these approaches based on hosting, scope and size, content acquisition and eligibility, content format and search, and evaluation and engagement characteristics; and (iii) review evaluations of the design, usefulness and impact of their online QI practice repositories. The search strategy consisted of traditional database and grey literature searches, as well as expert consultation, with the ultimate aim of identifying and describing QI repositories of practices undertaken in a healthcare context. We identified 13 QI repositories and found substantial variation across the five categories. The QI repositories used different terminology (eg, practices vs case studies) and approaches to content acquisition, and varied in terms of primary areas of focus. All provided some means for organising content according to categories or themes and most provided at least rudimentary keyword search functionality. Notably, none of the QI repositories included evaluations of their impact. With growing interest in sharing and spreading best practices and increasing reliance on QI as a key contributor to health system performance, the role of QI repositories is likely to expand. Designing future QI repositories based on knowledge of the range and type of features available is an important starting point for improving their usefulness and impact.

Full Text Available This paper investigates interactions between game theoretical strategies and social relationships in real-time decision-making and rewarding environments. We propose an experimental framework based on techniques of web-based multiplayer online games for this purpose. In our framework, multiple human players, represented as particles in a two-dimensional space of social interactions, can modify their positions and game strategies for the prisoner's dilemma in real time, and receive benefit or cost emerging from both game theoretical and social relationships with neighboring players. We report on experiments with human participants in different conditions of the payoff matrix, which reflects game structures, and the speed of each player, which reflects the ability to change her social relationship. We show that cooperative relationships emerge in real human groups regardless of experimental settings, and show their basic behavioral patterns. We further discuss relationships between behavioral characters of participants in the experiments and their psychological characters to see how their personalities can be reflected in their behavior in such a game theoretical framework, and show that a few psychological characters of participants might reflect their behavioral characters at least in part, but there were variations in these relationships between experimental groups.

Online chatting is an important component of improving interpersonal relationships online, but it may reduce participants' communication time with family members. We conducted a study of the relationship between participants' intent to engage in online chatting and three dimensions of loneliness: social, familial, and romantic. This study was designed to show the effect of online chatting on each of these three dimensions of loneliness. The participants in the study were 709 students at two universities in Taiwan who were classified on the basis of whether or not they had ever engaged in online chatting. Of the participants, 651 (91.82%) fully completed the questionnaires that served as the study instruments and were included in data analysis. The study found that individuals who had participated in online chatting exhibited greater familial loneliness than those who had not because the time spent in online chatting reduced the time spent in familial relationships. Social loneliness was related to the quality of Internet relationships rather than to the time spent online. Individuals who participated in online chatting had less romantic loneliness because of a greater ease of maintaining romantic relationships online. We conclude that online chatting can reduce social loneliness through high-quality Internet relationships but may exacerbate familial loneliness.

Full Text Available Lately, the quality management has integrated more and more among its components Corporate Social Responsibility (CSR. With strong roots in the foundation for sustainable development, protection of the environment, issues of social justness and economic growth, CSR raises numerous issues related to obtaining profits, business performance and firms and activities based on the quality of management. From the point of view of the last issues, the models of quality management built on the fundamental principles of quality become the foundation and catalyst for the effective implementation of CSR in organizations. This is the reason why it is necessary to investigate the extent to which quality management models provide frameworks and guidelines for integrating CSR in the management of quality and, moreover, in the management of the organization, with a clear focus on the extent to which the concept can be institutionalized and operated by the organization.

Full Text Available This paper reports on an empirical study of the multidimensionality of partnership quality and the relationships between these dimensions. A two-phase survey was conducted for a range of organisations from different industry sectors to collect empirical data to test the validity and reliability of the measurement model for the multidimensionality of partnership quality. The measurement model for partnership quality was confirmed by the results of the data analyses. This research also aimed to identify the significant relationships between these dimensions using a second generation multivariate analysis technique—partial least squares(PLS. The findings from results of the data analyses show that inter-organisational trust, shared business understanding and to a lesser extent, functional and dysfunctional conflict between the client organisation and the outsourcing vendor in an IT outsourcing relationship are the key determinants of partnership quality. The key outcome of high partnership quality between the client organisation and the outsourcing vendor in an IT outsourcing relationship is mutual beneficial sharing of risks and benefits. Commitment is confirmed as a multidimensional construct of behaviour and temporal/continuance commitment but is not is influenced by the other dimensions of partnership quality. Trust and shared business understanding are the key drivers in the IT outsourcing relationship ensuring that the sharing of risks and benefits are realised and conflict is minimised leading to a high quality and ultimately successful partnership between the client organisation and the outsourcing vendor. Furthermore behavioural commitment to the contractual obligations of an IT outsourcing relationship sustains an ongoing temporal commitment to the partnership between the client organisation and the outsourcing vendor.

This study of 168 dual-earner couples examined the relationship between workaholism and relationship satisfaction. More specifically, on the basis of the literature, it was hypothesized that workaholism is positively related to work-family conflict. In addition, the authors predicted that workaholism is related to reduced support provided to the partner, through work-family conflict, and that individuals who receive considerable support from their partners are more satisfied with their relationship. Finally, the authors hypothesized direct crossover of relationship satisfaction between partners. The results of structural equation modeling analyses using the matched responses of both partners supported these hypotheses. Moreover, in line with predictions, the authors found that gender did not affect the strength of the relationships in the proposed model. The authors discuss workplace interventions as possible ways to help workaholics and their partners.

Individuals who are unhappy in their intimate partnerships are at risk for developing alcohol problems. But little is known about the mechanisms underlying this link. One possibility is that couples with poor relationship quality gain more reinforcement from alcohol in certain contexts-a possibility that has never previously been empirically examined. In the current study, 304 individuals (152 couples) were assigned to receive alcohol (target BAC .08%) or a non-alcoholic beverage. They then engaged in a conflict-resolution interaction with their partners. Videotaped interactions were coded by trained observers. Results revealed a significant interaction between alcohol and relationship quality across multiple measures. Alcohol decreased negative behaviors, decreased negative reciprocity, and enhanced self-reported experience to a greater extent during interactions involving individuals reporting low relationship quality and had comparatively little effect among those reporting high relationship quality. Findings point to a potential mechanism underlying problem drinking among couples with poor relationship quality.

Full Text Available Rapidly advancing computer based technologies offer many possibilities for innovation in educational and administrative assessment tasks which allow for a reliable real time reporting and feedback process. This paper considers the requirements for teacher assessments to become an accurate and reliable process. As a case study, the challenges of implementing such a system at Koya University have been considered. This paper examines how a paperless online system can support faculties' efforts for improving sustainable quality in learning and up-to-date assessment techniques. The proposed sustainable paperless online system (SPOS uses Google Applications for Education that have been adopted at Koya university as a communications and collaboration medium to enhance its teaching quality. Such a system may enhance security, transparency and ease of use while consuming less time and resources and promoting green practice. The work throughout this paper explains how the initiative is engineered for achieving and monitoring a better quality in teaching.

This study examined whether individuals with different personality types (i.e., overcontrollers, undercontrollers, resilients) had different friendship quality development throughout adolescence. It also investigated whether personality types were indirectly related to romantic relationship quality in young adulthood, via friendship quality development in adolescence. The study employed six waves of longitudinal questionnaire data from Dutch youths who had a romantic relationship when they were young adults. Two age cohorts were followed, from 12 to 21 years and from 16 to 25 years, respectively. Findings showed that resilients reported higher mean levels of friendship quality during adolescence (i.e., more support from, less negative interaction with and less dominance from their best friend) than both overcontrollers and undercontrollers. Through the mean levels of friendship quality throughout adolescence, resilients indirectly experienced higher romantic relationship quality during young adulthood than both overcontrollers and undercontrollers. Thus, results provide support for a developmental model in which adolescent friendship quality is a mechanism linking personality types with young adulthood romantic relationship quality.

A clear definition of 'alcohol quality' is currently not available and the use of the term varies considerably depending on the scientific field and the individual author. Intrinsic factors of 'alcohol quality' may be taste and flavour or the absence of certain toxic contaminants. Extrinsic factors may include price, brand image, labelling or perceived authenticity, which are typically unrelated to public health outcomes. This article shows that using the term 'alcohol quality' with varying definitions and underlying concepts may lead to misunderstandings, if not to clear misinformation (sometimes also intentionally by industry) when 'lower quality' is interpreted as 'more toxic' especially in the case of substitution of commercial beverages to unrecorded alcohol. We suggest the use of clearly defined terms instead, such as 'taste quality' or 'brand price', whenever possible.

Co-rumination, the tendency to dwell on negative events and feelings with a relationship partner, is an aspect of relationships that has been associated with socioemotional adjustment tradeoffs and is found to be associated with depressive symptoms. However, depending on the context in which it occurs, co-rumination is not necessarily associated with detriments to mental well-being. Differences in relationship quality within certain relationships may explain why co-rumination is not always associated with depressive symptoms. In the current study, we utilized self-report measures in an ethnically diverse sample (53.5 % non-White) of 307 first term college students (65 % female) in order to elucidate how co-rumination between roommates may be associated with depressive symptoms. We found that the association between co-rumination and depressive symptoms was moderated by relationship quality such that co-rumination in a high quality relationship was not associated with depressive symptoms whereas the opposite was true in low quality relationships. Moreover, we found moderated mediation, such that the variance in the association between co-rumination and depressive symptoms was explained via self-esteem, but only for those co-ruminating within a low quality relationship. These results suggest that relationship quality may impact the extent to which co-rumination is associated with depressive symptoms among first year college students.

In the present study, witnessing in-home violence and peer relationship quality are evaluated as to their relative impact on Post Traumatic Stress (PTS) symptoms among children aged 8 to 17 investigated by child protective services (CPS) for maltreatment exposure. The sample included 2151 children from the National Survey of Child and Adolescent Well-Being II (NSCAW II). Linear growth models were estimated to assess associations between changes in PTS symptoms, witnessing in-home violence, and peer relationship quality over time. Greater frequency of witnessing in-home violence at baseline (i.e. wave 1) was associated with higher baseline PTS symptoms (β = 0.44). Increases in witnessing in-home violence frequency over time (average annual change across three years) had a strong association with increases in PTS symptoms over time (β = 0.88). Baseline peer relationship quality was associated with fewer PTS symptoms at baseline (β = -0.45). Increases in peer relationship quality over time were strongly associated with declines in PTS symptoms over time (β = -0.68). Peer relationship quality at baseline did not moderate baseline or over time associations between witnessing in-home violence and PTS symptoms. The average decline in PTS symptoms due to decreases in witnessing in-home violence and increases in peer relationship quality was 0.51 and 0.65 standard deviations respectively, over the three-year study period. Reducing chronic witnessing in-home violence and promoting the development of healthy social relationships with peers are critical for PTS symptom recovery. Copyright © 2018 Elsevier Ltd.

The cardiovascular system may represent a significant pathway by which marriage and stress influence health, but research has focused on married individuals cross-sectionally. This study examined associations among chronic stress, negative spousal relationship quality, and systolic blood pressure over time among middle-aged and older husbands and wives. Participants were from the nationally representative longitudinal Health and Retirement Study. A total of 1,356 (N = 2,712) married and cohabitating couples completed psychosocial and biomeasure assessments in waves 2006 and 2010. Analyses examined whether Wave 1 (2006) relationship quality and stress were associated with changes in blood pressure over time. The effects of stress and negative relationship quality were dyadic and varied by gender. Husbands had increased blood pressure when wives reported greater stress, and this link was exacerbated by negative spousal relationship quality. Negative relationship quality predicted increased blood pressure when both members of the couple reported negative quality relations. Findings support the dyadic biopsychosocial model of marriage and health indicating: (a) stress and relationship quality directly effect the cardiovascular system, (b) relationship quality moderates the effect of stress, and (c) the dyad rather than only the individual should be considered when examining marriage and health. © The Author 2015.

As part of the national OpenNotes initiative, the Veterans Health Administration (VHA) provides veterans online access to their clinical progress notes, raising concern in mental health settings. The aim of this study was to examine the perspectives and experiences of mental health clinicians with OpenNotes to better understand how OpenNotes may be affecting mental health care. We conducted individual semi-structured interviews with 28 VHA mental health clinicians and nurses. Transcripts were analyzed using a thematic analysis approach, which allows for both inductive and deductive themes to be explored using an iterative, constant comparative coding process. OpenNotes is changing VHA mental health care in ways that mental health clinicians perceive as both challenging and beneficial. At the heart of these changes is a shifting power distribution within the patient-clinician relationship. Some clinicians view OpenNotes as an opportunity to better partner with patients, whereas others feel that it has the potential to undo the therapeutic relationship. Many clinicians are uncomfortable with OpenNotes, but acknowledge that this discomfort could both improve and diminish care and documentation practices. Specifically, we found that (1) OpenNotes is empowering patients, (2) OpenNotes is affecting how clinicians build and maintain the therapeutic relationship, and (3) mental health clinicians are adjusting their practices to protect patients and themselves from adverse consequences of OpenNotes. Our findings suggest that future research should monitor whether OpenNotes notes facilitates stronger patient-clinician relationships, enhancing patient-centered mental health care, or diminishes the quality of mental health care through disruptions in the therapeutic relationship and reduced documentation. ©United States Government.

Full Text Available Internet is causing to transform the profile of the everyday life, especially for the youth. Attractiveness of internet has caused that most youth being appealed to the internet friendships, rather than face to face interactions. The present research aimed to investigate the relation between internet usage and attitude towards internet friendship with opposite sex among students. The survey method and researcher constructed questionnaire is used to gather appropriate information. The statistical universe is all under-graduate and post-graduate students of Guilan University, and from among them, 372 students have been selected through proportionate stratified sampling method. The observed positive relations between attitude towards online friendship and internet usage reveal that quantity and quality of internet usage are important variables creating positive attitudes towards online friendships with opposite sex. In accordance with Giddens it can be said that increasing electronic interactions changed traditional attitudes regarding relations between two sexes. The observed relation between the age of students and attitude towards internet friendship reveals the combined effect of time and space factors on changing attitudes. In overall, expansion of internet usage as a part of the process of globalization has an special role on formation of new social meanings such as online friendship with opposite sex, which itself is an apparent feature of modern world.

Ubiquitous Internet access currently revolutionizes the way people acquire information by creating a complex, worldwide information network. The impact of Internet use on the doctor-patient relationship is a moving target that varies across sociodemographic strata and nations. To increase scientific knowledge on the patient-Web-physician triangle in Austria, this study reports findings regarding prevailing online health information-seeking behavior and the respective impact on doctor-patient interactions among a nonprobability convenience sample of Internet users. To investigate digital age group-specific influences, we analyzed whether digital natives and digital immigrants differed in their perspectives. The questionnaire-based online survey collected sociodemographic data and online health information-seeking behavior from a sample of 562 respondents (59% females, mean age 37 ± 15 years, 54% digital natives). Most respondents (79%) referred to the Internet to seek health information, making it the most commonly used source for health information, even more prevalent then the doctor. We found similar predictors for using the Internet as a source for health-related information across digital age groups. Thus, the overall generational gap seems to be small among regular Internet users in Austria. However, study participants expressed a rather skeptical attitude toward electronic exchange of health data between health care professionals and patients, as well as toward reliability of online health information. To improve adoption of electronic doctor-patient communication and patient empowerment, public education and awareness programs are required to promote consumer-centered health care provision and patient empowerment.

Objective Psychobiological traits may be associated with excessive Internet use. This study assessed the relationships between biogenetic traits, the amount of time spent in online game playing, and the genre of the online game being played. Methods Five hundred sixty five students who enjoyed one of the four types of games included in this study were recruited. The types of games examined included role playing games (RPG), real-time strategy games (RTS), first person shooting games (FPS), and sports games. Behavioral patterns of game play, academic performance, and player biogenetic characteristics were assessed. Results The amount of time that the participants spent playing online games was significantly greater on weekends than on weekdays. On weekends, the types of games with the largest numbers of participants who played games for more than three hours were ranked as follows: RPG and FPS, RTS, and sports games. The Young's Internet Addiction Scale (YIAS)score for the RPG group was the highest among the groups of the four types of game players. The time that participants spent playing games on weekdays was negatively associated with academic performance, especially for the RPG and FPS groups. Compared with the other groups, the RPG and RTS groups had higher novelty seeking (NS) scores and self-directedness (SD) scores, respectively. Additionally, the sports game group had higher reward dependency scores than the other groups. Conclusion These results suggest that RPGs may have specific factors that are attractive to latent game addicts with higher NS scores. Additionally, excessive playing of online games is related to impaired academic performance. PMID:20396428

Substantial research has focused on patients' health information-seeking behavior on the Internet, but little is known about the variables that may predict patients' willingness to undergo online treatment and willingness to pay additionally for online treatment. This study analyzed sociodemographic variables, psychosocial variables, and variables of Internet usage to predict willingness to undergo online treatment and willingness to pay additionally for online treatment offered by the general practitioner (GP). An online survey of 1006 randomly selected German patients was conducted. The sample was drawn from an e-panel maintained by GfK HealthCare. Missing values were imputed; 958 usable questionnaires were analyzed. Variables with multi-item measurement were factor analyzed. Willingness to undergo online treatment and willingness to pay additionally for online treatment offered by the GP were predicted using 2 multiple regression models. Exploratory factor analyses revealed that the disposition of patients' personality to engage in information-searching behavior on the Internet was unidimensional. Exploratory factor analysis with the variables measuring the motives for Internet usage led to 2 separate factors: perceived usefulness (PU) of the Internet for health-related information searching and social motives for information searching on the Internet. Sociodemographic variables did not serve as significant predictors for willingness to undergo online treatment offered by the GP, whereas PU (B=.092, P=.08), willingness to communicate with the GP more often in the future (B=.495, Pcommunication with the GP (B=.198, Pmotive (B=.178, P=.002) were significant predictors. Age, gender, satisfaction with the GP, social motive, and trust in the GP had no significant impact on the willingness to pay additionally for online treatment, but it was predicted by health-related information-seeking personality (B=.127, P=.07), PU (B=-.098, P=.09), willingness to undergo online

The friendship paradox is the phenomenon that in social networks, people on average have fewer friends than their friends do. The generalized friendship paradox is an extension to attributes other than the number of friends. The friendship paradox and its generalized version have gathered recent attention due to the information they provide about network structure and local inequalities. In this paper, we propose several measures of nodal qualities which capture different aspects of their activities and influence in online social networks. Using these measures we analyse the prevalence of the generalized friendship paradox over Twitter and we report high levels of prevalence (up to over 90% of nodes). We contend that this prevalence of the friendship paradox and its generalized version arise because of the hierarchical nature of the connections in the network. This hierarchy is nested as opposed to being star-like. We conclude that these paradoxes are collective phenomena not created merely by a minority of well-connected or high-attribute nodes. Moreover, our results show that a large fraction of individuals can experience the generalized friendship paradox even in the absence of a significant correlation between degrees and attributes.

The objective of this project was to develop a computer vision system (CVS) for objective measurement of pork loin under industry speed requirement. Color images of pork loin samples were acquired using a CVS. Subjective color and marbling scores were determined according to the National Pork Board standards by a trained evaluator. Instrument color measurement and crude fat percentage were used as control measurements. Image features (18 color features; 1 marbling feature; 88 texture features) were extracted from whole pork loin color images. Artificial intelligence prediction model (support vector machine) was established for pork color and marbling quality grades. The results showed that CVS with support vector machine modeling reached the highest prediction accuracy of 92.5% for measured pork color score and 75.0% for measured pork marbling score. This research shows that the proposed artificial intelligence prediction model with CVS can provide an effective tool for predicting color and marbling in the pork industry at online speeds.

Full Text Available Marxian theory has long viewed the institution of private property as central to labour exploitation. After all, private property laws allow those who control the means of production to expropriate surplus value from the dispossessed. An analogous relationship arguably defines life on the Internet, where users are forced to venture onto privately owned digital enclosures to access key services. Yet these online property relationships are anything but settled and uncontested. Outside the digital enclosures of Apple and Google, the Internet has fostered the development of “commons-based peer production”, where key resources (e.g. software are produced without anyone claiming exclusive property rights. In fact, some scholars have argued that the rise of peer production on the web has begun to re-shape popular attitudes concerning the legitimacy of property exclusions more broadly. In short, as we become “property outlaws” on the web, we come to question the inevitability and legitimacy of private property elsewhere in life. This paper explores this hypothesis by reporting data from a survey of Internet users at an East Coast university. Are users who engage in more peer production activities on the web also more likely to approve of “property outlaw” behaviours not just in the online context, but in the offline world as well (e.g. squatting? The data provide only partial support for the hypothesis: active online peer producers were indeed more likely to support violations of intangible (intellectual properties, but not violations of tangible or “real-world” properties.

Online health searches are common and may be impacting patients and their relationships with their clinicians in ways that are not fully understood. We searched PubMed, Embase, Cochrane Reviews, Cochrane Trials, Scopus, and CINAHL from 1 January 1990 to 29 January 2016 for studies in which patients searched online for any aspect of healthcare and then visited their clinician. We extracted data pertaining to either patients' or clinicians' perceptions of the effects of these online searches on patients and the patient-clinician relationship. Searches seemed to induce patient anxiety but more often led to patient reassurance, clinical understanding, and empowerment. Patients tended to perceive that online health searches had a positive effect on the patient-clinician relationship, though the nature of the effect could depend on the clinician's response to patient queries regarding the information. Clinicians generally perceived neutral effects on patients and the patient-clinician relationship, and commonly raised concerns about accuracy of online content. Significant methodological heterogeneity prevented quantitative synthesis. Accuracy of online health search content was not assessed, and randomized controlled trials were notably lacking.

In recent years, providers of massage therapy education have, in growing numbers, started to use online technologies to support the learning processes of their students. Using a narrative review of the existing online learning literature, this paper aims to provide a solid pedagogical foundation for these early explorations. It identifies five key factors—instructional pedagogy, quality of instruction, interaction and communication, individual learner qualities, and the online interface—that contribute to student satisfaction and achievement in the online context. The relationships between those factors and the experience of the online learner are discussed with reference to maximization of student satisfaction and achievement. PMID:21589705

Research purpose: The aim of the study was to determine the relationship between organisational trust and QWL. Motivation for the study: Recent organisational changes have refocused attention on the productivity and performance of sales representatives. These changes have brought about a re-evaluation of their QWL and the organisational trust they experience. Research design, approach and method: An Internet-based survey methodology was used to collect primary data from a probability sample of 282 sales representatives; a 72% response rate was obtained. Responses were analysed using quantitative techniques and structural equation modelling. Main findings: Results confirmed a positive relationship between managerial practices with organisational trust and QWL and a lower relationship between the personality dimensions, organisational trust and the QWL. Practical/managerial implications: The study accentuated how important it is for management to be constantly aware of employees’ trust and their experience of a QWL, as these factors can lead to severe consequences if not properly managed. Contribution/value add: The study focused attention on the importance of building good trust relationships within an organisation, as it seems as though the personality traits and managerial practices of managers influence not only the trust relationship experienced by employees, but also their experience of a QWL.

This paper reports about experiences gathered from five online monitoring campaigns in the sewer systems of Berlin (Germany), Graz (Austria), Lyon (France) and Bogota (Colombia) using ultraviolet-visible (UV-VIS) spectrometers and turbidimeters. Online probes are useful for the measurement of highly dynamic processes, e.g. combined sewer overflows (CSO), storm events, and river impacts. The influence of local calibration on the quality of online chemical oxygen demand (COD) measurements of wet weather discharges has been assessed. Results underline the need to establish local calibration functions for both UV-VIS spectrometers and turbidimeters. It is suggested that practitioners calibrate locally their probes using at least 15-20 samples. However, these samples should be collected over several events and cover most of the natural variability of the measured concentration. For this reason, the use of automatic peristaltic samplers in parallel to online monitoring is recommended with short representative sampling campaigns during wet weather discharges. Using reliable calibration functions, COD loads of CSO and storm events can be estimated with a relative uncertainty of approximately 20%. If no local calibration is established, concentrations and loads are estimated with a high error rate, questioning the reliability and meaning of the online measurement. Similar results have been obtained for total suspended solids measurements.

Full Text Available Love is one of the most desired feelings by human beings. According to the triangular theory of love, it is composed of three elements: intimacy, passion and decision/commitment, which constitutes a dimension related to the quality of love the partners perceive in their relationship. This study aims to compare the three elements of love and marital quality of 86 Internet users (43 in a relationship mediated by the Internet and 43 with a physical relationship. The results indicate that there is a significant difference in the intimacy, the decision/commitment and the whole dimension of love, as well as in the marital quality between partners who have a relationship mediated by Internet and the ones in a physical relationship. We can conclude that the Internet is a great tool for people to meet, but that it is important for the relationship to develop in a face-to-face context.
Full Text Available A sensitive on-line DPPH-CE-DAD method was developed and validated for both screening and determining the concentration of seven antioxidants of Reduning injection. The pH and concentrations of buffer solution, SDS, β-CD and organic modifier were studied for the detection of DPPH and seven antioxidants. By on-line mixing DPPH and sample solution, a DPPH-CE method for testing the antioxidant activity of the complex matrix was successfully established and used to screen the antioxidant components of Reduning injection. Then, antioxidant components including caffeic acid, isochlorogenic acid A, isochlorogenic acid B, isochlorogenic acid C, chlorogenic acid, neochlorogenic acid and cryptochlorogenic acid were quantified by the newly established CE-DAD method. Finally, the total antioxidant activity and the multiple active components were selected as markers to evaluate the quality of Reduning injection. The results demonstrated that the on-line DPPH-CE-DAD method was reagent-saving, rapid and feasible for on-line simultaneous determination of total pharmacological activity and contents of multi-components samples. It was also a powerful method for evaluating the quality control and mechanism of action of TCM injection.

Water quality data for 65 variables were obtained for the period 1955 to 1977 and aggregated on a county basis. Measurements were taken primarily in New England and the Middle Atlantic States. When a subset of 138 counties with complete data was used, it was found that county aggregation statistical procedures resulted in data still able to describe the chemical characteristics of natural waters. Energy and socioeconomic data were merged with water quality data for these 138 counties. The path analytic methodology used by geneticists was adapted for use with these combined data to investigate for potential interactions between energy-related activities and water quality. A path diagram was proposed to provide insight into the possible causal nature of these interrelations. Direct and indirect pathways from energy production and use were traced to three factors describing functional attributes of water: conductivity, hardness, and dissolved metallic ions. This analysis explained 25 to 40% of the variance in three water quality factors and indicated the applicability of this technique to regional assessments of water quality impacts due to many human activities

This study examined the associations between adolescents' perceived relationships with their parents, perceived parental online behaviors, and Pathological Internet Use (PIU) among adolescents. Additional testing was carried out to determine the effect of different genders (parent and adolescent). Cross-sectional data was collected from 4,559 students aged 12 to 21 years in the cities of Beijing and Jinan, People's Republic of China. Participants responded to an anonymous questionnaire concerning their Internet use behavior, perceived parental Internet use behaviors, and perceived parent-adolescent relationship. Hierarchical linear regressions controlling for adolescents' age were conducted. Results showed different effects of parent and adolescent gender on perceived parent-adolescent relationship and parent Internet use behavior, as well as some other gender-specific associations. Perceived father-adolescent relationship was the most protective factor against adolescent PIU with perceived maternal Internet use positively predicting PIU for both male and female adolescents. However, perceived paternal Internet use behaviors positively predicted only female adolescent PIU. Results indicated a different effect pathway for fathers and mothers on boys and girls, leading to discussion of the implications for prevention and intervention.

Pesanggrahan River watershed has several activities such as residential and commercial area in its catchment area. The purpose of this study was to analyse water quality related to spatial land use in Pesanggrahan River using GIS Analysis. River water quality in some locations, did not meet water quality standard of class III. From pollution load estimation it was revealed that segment 2 (Bogor City) has the highest BOD, COD, and TSS of 15,043 kg/day, 25,619 kg/day, and 18,104 kg/day respectively. On the other hand, the most developed area in Pesanggrahan Watershed is located in segment 7 (24.5%). Hence, it can be concluded that although an area has a fairly small developed area, high urban activity can cause high BOD, COD, and TSS.

This book presents guidelines on quantitative and qualitative measures of the geometric features and imperfections of welds to ensure that it meets the fatigue strength requirements laid out in the recommendations of the IIW (International Institute of Welding). Welds that satisfy these quality criteria can be assessed in accordance with existing IIW recommendations based on nominal stress, structural stress, notch stress or linear fracture mechanics. Further, the book defines more restrictive acceptance criteria based on weld geometry features and imperfections with increased fatigue strength. Fatigue strength for these welds is defined as S-N curves expressed in terms of nominal applied stress or hot spot stress. Where appropriate, reference is made to existing quality systems for welds.In addition to the acceptance criteria and fatigue assessment curves, the book also provides guidance on their inspection and quality control. The successful implementation of these methods depends on adequate training for o...

While there are a number of studies examining the relationship between nurse staffing and quality, none has examined structural differences in the relationship between nurse staffing and quality contingent upon the level of managed care penetration. We used administrative data, and a dynamic panel data model to examine this relationship in a panel of 422 acute care hospitals from 1990 to 1995. We found that there were significant differences in the relationship between nurse staffing and both mortality and length of stay depending upon the level of HMO penetration in the hospital's market.

The relationship between financial performance and quality of care in nursing homes is not well defined and prior work has been mixed. The recent focus on improving the quality of nursing homes through market-based incentives such as public reporting may have changed this relationship, as public reporting provides nursing homes with increased incentives to engage in quality-based competition. If quality improvement activities require substantial production costs, nursing home profitability may become a more important predictor of quality under public reporting. This study explores the relationship between financial performance and quality of care and test whether this relationship changes under public reporting. Using a 10-year (fiscal years 1997-2006) panel data set of 9444 skilled nursing facilities in the US, this study employs a facility fixed-effects with and without instrumental variables approach to test the effect of finances on quality improvement and correct for potential endogeneity. The results show that better financial performance, as reflected by the 1-year lagged total profit margin, is modestly associated with higher quality but only after public reporting is initiated. These findings have important policy implications as federal and state governments use market-based incentives to increase demand for high-quality care and induce providers to compete based on quality.

The majority of the world population profess religious/spiritual beliefs and prayer is a form of spiritual activity common across numerous religious/spiritual belief systems. Three studies therefore examined the role of prayer in romantic relationships. Study 1 (n = 91) showed that prayer for a dating partner predicted lower aggressive tendencies and greater forgiveness of partner transgressions, independently of relationship closeness. Study 2 (n = 89 married couples) is among the first to examine the prayer-forgiveness association using dyadic data. Controlling for relationship satisfaction in the actor-partner interdependence model, prayer for the spouse predicted own forgiveness but not partner's reports of their own forgiveness. To obviate the problem of obtaining all the data from the same reporter, Study 3 (n = 91 married couples) used partner reports of the spouse's forgiveness in an actor-partner interdependence model analysis. Controlling for religiosity, the results showed that prayer for the partner predicted partner reports of the prayer's forgiveness. The implications of these results are then discussed.

Sibling relationship quality and social understanding (second-order false belief, conflict interpretation, and narrative conflict perspective references) were examined as unique and interactive correlates of sibling conflict behavior in 62 dyads (older M age = 8.39 years and younger M age = 6.06 years). High-quality relationships were associated with positive conflict processes. Younger siblings' second-order false belief scores were negatively associated with constructive conflict strategies, and older siblings' narrative self-referential focus was negatively associated with compromise. Associations between younger children's social understanding (conflict interpretation and narrative perspective references) and siblings' dyadic conflict behavior were moderated by relationship quality. Results suggest that links between social understanding and conflict behavior should be considered in conjunction with the quality of children's relationships.

Resistance spot welding is the main joining technique used for the fabrication of body-in-white structures in the automotive industry. The quality of the welds depends on the profile of the spot welding electrode cap. The increased use of zinc coated steel in the industry increases wear rate of the caps, making quality control more difficult. This paper presents a novel online real time ultrasonic NDE system for resistance spot welding which evaluates every weld as it is formed. SEM results are presented to show the alloying of the electrode caps.

The constantly increasing utilization of social media as the alternative information channel, e.g., Twitter, provides us a unique opportunity to investigate the dynamics of the financial market. In this paper, we employ the daily happiness sentiment extracted from Twitter as the proxy for the online sentiment dynamics and investigate its association with the skewness of stock returns of 26 international stock market index returns. The empirical results show that: (1) by dividing the daily happiness sentiment into quintiles from the least to the most happiness days, the skewness of the Most-happiness subgroup is significantly larger than that of the Least-happiness subgroup. Besides, there exist significant differences in any pair of subgroups; (2) in an event study methodology, we further show that the skewness around the highest happiness days is significantly larger than the skewness around the lowest happiness days.

The aim of this paper was to investigate the association between appetite and kidney-disease specific quality of life in maintenance hemodialysis patients. Quality of life (QoL) was measured using the kidney disease quality of life survey. Appetite was measured using self-reported categories and a visual analog scale. Other nutritional parameters included Patient-Generated Subjective Global Assessment (PGSGA), dietary intake, body mass index and biochemical markers C-reactive protein and albumin. Even in this well nourished sample (n=62) of hemodialysis patients, PGSGA score (r=-0.629), subjective hunger sensations (r=0.420) and body mass index (r=-0.409) were all significantly associated with the physical health domain of QoL. As self-reported appetite declined, QoL was significantly lower in nine domains which were mostly in the SF36 component and covered social functioning and physical domains. Appetite and other nutritional parameters were not as strongly associated with the Mental Health domain and Kidney Disease Component Summary Domains. Nutritional parameters, especially PGSGA score and appetite, appear to be important components of the physical health domain of QoL. As even small reductions in nutritional status were associated with significantly lower QoL scores, monitoring appetite and nutritional status is an important component of care for hemodialysis patients.

Full Text Available In three studies, we examined assortative mating for psychopathy components as well as its effects on the relationship quality in intimate partners. Compared to the original structure we confirmed three factors of psychopathy: criminal tendencies (CT, erratic lifestyle (ELS and interpersonal manipulation (IM, while callous affect (CA was not replicated. Hypotheses regarding positive versus negative assortment, initial assortment versus convergence, and active assortment versus social homogamy were tested. All hypotheses were examined using both variable-centered approach (VCA and couple-centered approach (CCA. We found moderate positive assortment between intimate partners in psychopathy as a latent construct estimated by structural modelling. Furthermore, positive assortment for all three components of psychopathy was found either by using only VCA (CT, only CCA (IM or both approaches (ELS. Additionally, initial assortment rather than convergence hypothesis and active assortment rather than social homogamy hypothesis was confirmed for all three psychopathy components, with a slight tendency towards divergence and social homogamy. We explored the effects of similarity in psychopathy components on the women and men' relationship quality by using profile similarity and polynomial regression analyses. Profile similarity in IM was significantly positively related to women's relationship quality, while the results of the polynomial regression analyses were more complex, and showed that only (dissimilarity in CT did not exert any effect on women and men's relationship quality. Greater disagreement between women and men's ELS was related with more sharp decrease of women's relationship quality, while men's relationship quality decreased at the higher levels of women and men's ELS. Greater disagreement between women and men's IM results in a lower women's relationship quality, while women and men's relationship quality was higher when women's IM was

Motor function, cognition, functional independence and quality of life have been described in myelomeningocele patients, but no study has investigated their relationships. We aimed to investigate the relationships between motor function, cognition, functional independence, quality of life, age, and lesion level in myelomeningocele patients, and investigate the influence of hydrocephalus on these variables. We assessed 47 patients with the Gross Motor Function Measure (motor function), Raven's Colored Progressive Matrices (cognition), Pediatric Evaluation of Disability Inventory (functional independence) and the Autoquestionnaire Qualité de vie Enfant Imagé (quality of life). Spearman's correlation tests determined relationships between the variables. The Friedman ANOVAs determined the influence of hydrocephalus. Motor function was strongly related to mobility and lesion level, and moderately related to cognition, self-care and social function. Cognition and quality of life were moderately related to functional independence. Age correlated moderately with functional independence and quality of life. Hydrocephalus resulted in poorer motor/cognitive outcomes and lower functional independence.
Full Text Available Background. The question whether old media are driven out of existence by new media has been a long concern in academic and industrial research but has received no definitive answer. Aim.This paper goes beyond most previous studies of Internet impact on traditional media, which have placed their relationship within a competition-based framework, to specifically investigate the complementary effect of online news and information usage on traditional sources. Method. Secondary data analysis of a national survey of 4270 Australians conducted in late 2003, employing hypothesis testing for the mean, partial correlations, and a linear regression analysis. Results. Online news and information usage at different usage levels is positively associated with the use of traditional news and information sources, especially those that are more information-intensive. Those who relied on the Internet the most for news and information still used traditional sources substantially. Conclusion. The findings suggest that even if a displacement effect takes place, there will be no replacement (absolute displacement: traditional media will still exist to complement the Internet in serving human beings' news and information needs.

Past research has demonstrated negative associations between exposure to stressors and quality of interpersonal relationships among children and adolescents. Nevertheless, underlying mechanisms of this association remain unclear. Chronic stress has been shown to disrupt prefrontal functioning in the brain, including inhibitory control abilities, and evidence is accumulating that inhibitory control may play an important role in secure interpersonal relationship quality, including peer problems and social competence. In this prospective longitudinal study, we examine whether changes in inhibitory control, measured at both behavioral and neural levels, mediate the association between stress and changes in secure relationship quality with parents and peers. The sample included 167 adolescents (53% males) who were first recruited at age 13 or 14 years and assessed annually three times. Adolescents' inhibitory control was measured by their behavioral performance and brain activities, and adolescents self-reported perceived stress levels and relationship quality with mothers, fathers, and peers. Results suggest that behavioral inhibitory control mediates the association between perceived stress and adolescent's secure relationship quality with their mothers and fathers, but not their peers. In contrast, given that stress was not significantly correlated with neural inhibitory control, we did not further test the mediation path. Our results highlight the role of inhibitory control as a process through which stressful life experiences are related to impaired secure relationship quality between adolescents and their mothers and fathers.

With online shopping entering a consolidation phase, there is a need for research differentiating online consumer behavior for a range of prod-uct categories. Also, individual differences in online shopping need to be considered. Therefore, a survey (N = 405) assessing online infor-mation search and online shopping for nine different product categories as well as socio-demographic and individual variables (shopping orien-tation, need for emotion, and fashion leadership) was conducted in Germa...
