A Novel Travel Group Recommendation Model Based on User Trust and Social Influence

The interactions between group members often have a significant impact on the results of group recommendations. The traditional group recommendation algorithm does not consider the trust and social influence among users. It involves a low utilization rate of social relationship information, which leads to a low accuracy and satisfaction of group recommendations. Considering these issues, in this study, we propose a travel group recommendation model based on user trust and social influence. Based on the user trust relationship, this model defines the user direct and indirect trust and calculates the user global trust by combining the two trusts. Subsequently, the PageRank algorithm is used to calculate the social influence of users based on their interaction relationship history. Thereafter, a consensus model integrating the intra- and intergroup prediction scores is designed by integrating users’ global trust and social influence to realize group recommendations for tourist attractions. Comparison experiments with several well-known group recommendation models for datasets of different scenic spots in Beijing demonstrate that the proposed model provides a better recommendation performance.

Keeping the Flame Alive: Describing Marriage and Divorce Among Professional Firefighters

There is a common belief, but little empirical evidence, that firefighters are uniquely vulnerable to divorce. The present study aimed to examine key demographic and occupational factors related to divorce among firefighters. Online survey data (relationship status, relationship history, demographics, and occupational history) were collected from 163 firefighters in an urban city of the Southern United States. Divorced firefighters were older, in fire service longer, and younger at the age of their first marriage compared to non-divorced firefighters. Firefighters who married before joining fire service were more likely to experience divorce than firefighters who married after joining fire service; however, after controlling for age and age at first marriage, this effect became nonsignificant. Divorce was reported by firefighters at greater rates than the general population, and most divorces occurred after entry into fire service. However, non-occupational factors may better explain this trend.

Supply chain governance: a conceptual model

Purpose This paper aims to clarify ambiguous results from previous research on the relationship between contextual factors, trust and supply chain governance (SCG). Design/methodology/approach This study carried out a systematic literature review in 11 databases, with articles published until 2018. Afterward, this study conducted a thematic analysis in 60 articles to address the contextual factors, governance structures and trust approaches raised in previous research. Findings The thematic analysis revealed that seven contextual factors influence the choice of contractual and relational mechanisms in supply chains: relationship history, environmental uncertainty, perceived risk, perceived justice, asset specificity, power asymmetry and interdependence. The findings explained the ambiguous results of past research by proposing that contractual and relational governance are complementary and that the presence of trust (affective and competence-based) moderates the relationship between contextual factors and SCG. Originality/value This research advances the SCG literature by proposing trust (affective and competence-based) as a moderating variable that fosters governance mechanisms in supply chain relationships.

Unearthing the Facets of Crisis History in Crisis Communication: A Conceptual Framework and Introduction of the Crisis History Salience Scale

Coombs’s Situational Crisis Communication Theory suggests performance history, composed of relationship history and crisis history, intensify crisis responsibility attribution. Relationship history is organizations’ actual and perceived rapport with publics, while crisis history is an organization’s previous crises. Extant literature has only examined crisis history one-dimensionally. This study proposes the Crisis History Framework that provides insight into influential factors that can make crises more or less salient to individuals. Furthermore, the study introduces the Crisis History Salience Scale that can help crisis communications scholars conduct empirical research examining crisis history’s multiple facets. Moreover, the study offers suggestions for how crisis history considerations can inform proactive crisis management, key messaging, and strategy development during crises.

Exploring parents’ ongoing role in romantic development: Insights from young adults

Important decisions about romantic relationships are often made during adulthood, but the foundations for healthy relationships begin during childhood. Romantic development is related to experiences in the family of origin such as parenting, parents’ romantic history, and patterns of interaction within families. In order to better understand how this process unfolds into adulthood, we used relationship history interviews from 35 young adults (ages 24–40) to explore the mechanisms through which parents influence their children’s romantic development. We used Applied Thematic Analysis to guide our secondary analysis of relationship histories data. The findings suggest adult children internalize and apply the examples of parents whom they perceive to be good role models. When parents are seen as poor role models, young adults engage in trial and error as they look for partners that will help them avoid their parents’ mistakes and/or they commit to a partner at a young age to form a family of their own. Adult children also seek love, affirmation, and support from their romantic partners when they feel those things were lacking from their parents. We explore implications of these findings for future research on romantic development.

When (In)Consistency Matters: Racial Identification and Specification

Sociologists who rely on survey research have begun exploring the implications of racial inconsistency for not only multiracial identification but also for other social outcomes. Using the National Longitudinal Study of Adolescent to Adult Health, the author explores the consequences of different specifications of race for modeling three outcomes: educational attainment, self-rated health, and interracial relationship history. The author uses the model-fit criteria of Akaike information criterion and Bayesian information criterion to compare five methods of classifying multiple, changed, and other-race respondents and of operationalizing heterogeneity among them. The results show substantial variation across outcomes in the specifications preferred and indications of a qualitative difference in the meaning of race for social contact versus for social stratification. The article concludes with recommendations for how quantitative researchers should measure race even when the categories primarily serve as covariates.

The Relationship of Infectious Diseases History and Mother Factors to Under Red Line Among Toddler

Nutrition under the red line is a state of severe nutritional deficiency caused by low consumption of energy and protein from daily food. Sungai Tiung is the village that has the highest number of children under five with under red line (BGM) from other villages in the working area of Rawat Inap Cempaka Health Center. This study aims to know the relationship of infectious diseases history and mother factors to under red line (BGM) among toddler in Sungai Tiung. This research uses cross-sectional design. The samples are 90 respondents. Sampling used purposive sampling. The independent variables are a history of infectious disease, knowledge, education, and mother care pattern. The dependent variable is under red line (BGM). The instrument in this study used questionaire and Kartu Menuju Sehat (KMS). The result showed that there is a relationship history of infectious diseases with BGM (p-value = 0.03). The results also showed no relationship of knowledge (p-value = 0.12), education (p-value = 0.75) and mother care pattern (p-value = 0.32) with BGM. There is a relationship history of infectious diseases with BGM. So that, there should be efforts to prevent infectious diseases in toddler. Keywords : under red line, toddler, infectious diseases

How logistics performance is affected by supply chain relationships

Purpose The purpose of this paper is to evaluate the effect of logistics collaboration, meetings, relationship history, and supplier selection on the logistics performance of shippers, carriers, and logistics services providers. Rather than focusing on collaboration and performance, the research provides a wide analysis of how logistics collaboration and performance interact with other organizational practices. Design/methodology/approach To investigate the interaction among the constructs, the authors proposed a structural equation model to understand the influence of meetings, relationship history, supplier selection, and collaboration on logistics performance. The data were obtained through a survey of 199 managers of Brazilian companies in the retail sector. Findings Supplier selection has the strongest effect on logistics collaboration, and relationship history has the strongest effect on logistics performance. Rather than meetings and operational features, the elements of interpersonal skills, organizational culture, and communication appear to be the most important contributors to logistics performance achievements; relationship history leads to better performance. Originality/value This study contributes to our understanding of how and with whom to collaborate by highlighting the relationships among supplier selection, relationship history, meetings, and logistics collaboration and logistics performance.
