The Relationship Between Facebook Use and Well‐Being Depends on Communication Type and Tie Strength

An extensive literature shows that social relationships influence psychological well‐being, but the underlying mechanisms remain unclear. We test predictions about online interactions and well‐being made by theories of belongingness, relationship maintenance, relational investment, social support, and social comparison. An opt‐in panel study of 1,910 Facebook users linked self‐reported measures of well‐being to counts of respondents' Facebook activities from server logs. Specific uses of the site were associated with improvements in well‐being: Receiving targeted, composed communication from strong ties was associated with improvements in well‐being while viewing friends' wide‐audience broadcasts and receiving one‐click feedback were not. These results suggest that people derive benefits from online communication, as long it comes from people they care about and has been tailored for them.     

基于紧密型的兴趣度挖掘算法

关联规则采掘是数据挖掘中的重要课题,针对当前关联规则采掘中可能产生许多无效关联规则的问题,分析其原因,引入了紧密度的概率,通过此约束值,将事务集中两者紧密相联的项或是在很大程度上是紧密相联系的事务挖掘出来,其主导思想是一种事务的出现必然导致或大部分另一种事务的出现,根据此紧密性关联关系,将关联规则分为紧密性、高紧密性和非紧密性的关联关系。并对事务项进行实验分析,实验数据表明,新方法能减少无效的,非紧密的项集。

Association rule mining to detect factors which contribute to heart disease in males and females

This paper investigates the sick and healthy factors which contribute to heart disease for males and females. Association rule mining, a computational intelligence approach, is used to identify these factors and the UCI Cleveland dataset, a biological database, is considered along with the three rule generation algorithms – Apriori, Predictive Apriori and Tertius. Analyzing the information available on sick and healthy individuals and taking confidence as an indicator, females are seen to have less chance of coronary heart disease then males. Also, the attributes indicating healthy and sick conditions were identified. It is seen that factors such as chest pain being asymptomatic and the presence of exercise-induced angina indicate the likely existence of heart disease for both men and women. However, resting ECG being either normal or hyper and slope being flat are potential high risk factors for women only. For men, on the other hand, only a single rule expressing resting ECG being hyper was shown to be a significant factor. This means, for women, resting ECG status is a key distinct factor for heart disease prediction. Comparing the healthy status of men and women, slope being up, number of coloured vessels being zero, and oldpeak being less than or equal to 0.56 indicate a healthy status for both genders.

Student bystander behavior and cultural issues in cyberbullying: When actions speak louder than words

This study aims to investigate whether student bystander interventions can influence the relationship between being a bystander of a cyberbullying incident and being the victim or the aggressor. Another aim is to understand the specific behavior presented by students bystanders, namely whether they noticed incidents of cyberbullying and interpreted these events as an emergency and which actions they determined as being appropriate in providing assistance. Following a cross-cultural perspective to reach these aims, a total of 788 Portuguese and Brazilian college students answered to the Cyberbullying Inventory for College Students. Moderation analysis revealed that intervening moderated the relationship between being the bystander of cyberbullying and being the victim and/or aggressor. A three-way interaction showed that this relationship was stronger in Brazilian students, revealing that the bystanders who were inactive were more likely to also become a victim or an aggressor themselves, whereas those who intervened were less likely to become a victim or an aggressor. Implications for future research and interventive action are discussed.     

Predictors of Online Health Information Seeking Among Women with Breast Cancer: The Role of Social Support Perception and Emotional Well‐Being

This study attempts to examine the role of social support perception and emotional well‐being on online information seeking among cancer patients within the context of CHESS, a well‐established Interactive Cancer Communication System (ICCS). Factor and regression analyses conducted among 231 breast cancer patients revealed that social support perception and emotional well‐being interacted with each other to influence online health information seeking. Patients with low social support perception and high emotional well‐being were most likely to seek health information, whereas patients with high social support perception and high emotional well‐being sought out the same information least. Practical implications of the study findings are further discussed.
