Hadits adalah segala sesuatu yang disandarkan kepada Nasbi SAWbaik mengenai perkataan, pebuatan, taqrir dan sebagainya. Hadits merupakan sumber tasyri’ kedua. Secara global semua ulama mengakuinya, tetapi secara terperinci mereka berpendapat tentang kedudukan hadits sebagai dalil tasyri’, sebab hadits dilihat dari jumlah perawi yang ada yang dinamakan hadits ahad dan hadits mutawatir, sedangkan dilihat dari nilainya ada yang shahih dan ada yang dla’if.

BACKGROUND Diligent wear of removable orthodontic retainers requires prolonged compliance and is invariably necessary to preserve optimal results. Patient-informed behaviour-change interventions represent a promising and novel means of enhancing compliance with retainer wear. OBJECTIVE To describe the development of a patient-informed mobile application aimed to enhance retainer wear. METHODS Four aspects were considered during mobile application development: participant preferences; analysis of publicly-available retainer-related posts on Twitter; available interventions; and behaviour-change theories. Audio-recorded one-to-one interviews were conducted with a subset of participants to account for patient preferences in terms of features, design and content. A criterion-based purposive sample of participants wearing vacuum-formed retainers for at least 4 years was used. Thematic analysis of transcribed data was undertaken. RESULTS The need to facilitate communication with the treating clinician, responsive reminder and tracking systems, and access to useful and engaging written and visual information, in addition to other personalised and interactive features were considered important. Concerns related to retainer wear shared on Twitter informed an exhaustive list of frequently-asked questions. Application features were mapped to relevant theoretical constructs. Determinants of existing behavioural change theories were used to link application features to expected outcomes. CONCLUSIONS A holistic process involving both patient and professional input can be useful in informing the development of mobile applications. The orthodontic application (“My Retainers”) will undergo further scrutiny in relation to its effectiveness in inducing behavioural change and concerning patient experiences prior to finalisation.

Abstract Background Regular exercise and physical activity can maintain function and cardiovascular health, and prevent cognitive decline, in older adults. However, studies show that there is often poor adherence to home exercise programmes (HEP). The purpose of this study was to explore how HEP are perceived by both older adults and physiotherapists. Methods A convenience sample of 28 older adults attending outpatient physiotherapy clinics were given an exercise journal to record their adherence to the HEP prescribed by their physiotherapists for six weeks. Subsequently, semi-structured interviews were conducted with a purposive sample, and the corresponding prescribing physiotherapists, to achieve maximal variation in terms of HEP adherence, age and sex. The interviews were audio recorded, transcribed, and simple content analysis performed. Results Fourteen participants returned their exercise journal. Median age was 80; half were female; median Berg Balance Score and Timed-up-and-Go-Test were 49 and 16 seconds respectively. Participants exercised a median 79.8% of the prescribed dose, or 5.6 days per week. Seven older adults were interviewed; about half had a positive attitude towards exercise. They were also moderately positive about their HEP (comments ranged from “doable” and “nothing bad about it” to “enjoyable”). Barriers included time, mood, boredom, remembering to do the HEP, and variable health status. Enablers included simple instructions and design, family encouragement, and sense of achievement. Physiotherapists (n=5) perceived that many older adults aren’t compliant with HEPs, but there was some therapeutic nihilism (“you can’t force them”). Their HEP instructions varied from verbal to written instructions/diagrams; one physiotherapist used individualised video content. Notably, participants with good adherence understood their HEP well in terms of content and purpose, although this may be cause or effect. Conclusion To improve compliance with HEP, healthcare professionals need to take time to motivate the recipient, simplify their instructions, and trouble-shoot potential barriers at the time of prescription.

ObjectivesFamily caregivers suffer a high burden of emotional and psychological distress following the death of a loved one in the intensive care unit and often struggle to heal in the weeks following their loss. The purpose of this hermeneutic phenomenological study was to describe and interpret the experience of healing for family caregivers six weeks following the death of a loved one in the ICU.MethodsSemi-structured telephone interviews were conducted with a purposive sample of twenty-four family caregivers six weeks following the death of their loved ones in the ICU. Qualitative analysis techniques were used to identify common themes central to the experience of healing across all interviews.ResultsSeven themes were interpreted from the data: searching for clarity from a time of uncertainty; riding an emotional rollercoaster; seeking peace in one’s decisions; moving forward with each new day; taking comfort in the memories; valuing layers of support; and discovering life on one’s own.ConclusionBy identifying and gaining an understanding of healing following the death of a loved one in the ICU, nursing and other healthcare providers have an opportunity to promote healing and positively impact family caregiver’s bereavement.

Objective: Complicated grief is a debilitating condition that individuals may experience after losing a loved one. General practitioners (GPs) are well positioned to provide patients with support for grief-related issues. Traditionally, Irish GPs play an important role in providing patients with emotional support regarding bereavement. However, GPs have commonly reported not being aptly trained to respond to bereavement-related issues. This study explores GPs’ current knowledge of and practice regarding complicated grief. Methods: A qualitative study adopting a phenomenological approach to explore the experiences of GPs on this issue. Semi-structured interviews were carried out with a purposive sample of nine GPs (five men and four women) in Ireland. Potential participants were contacted via email and phone. Interviews were audio-recorded, transcribed and analysed using Braun & Clarke’s (2006) model of thematic analysis. Results: GPs had limited awareness of the concept of complicated grief and were unfamiliar with relevant research. They also reported that their training was either non-existent or outdated. GPs formed their own knowledge of grief-related issues based on their intuition and experiences. For these reasons, there was not one agreed method of how to respond to grief-related issues reported by patients, though participants recognised the need for intervention, onward referral and review. Conclusions: The research highlighted that GPs felt they required training in complicated grief so that they would be better able to identify and respond to complicated grief.

Utilizing an interactionist perspective, two associated sensitizing constructs, and a combination of social psychological theory, this article reports on the influence of the peer group on individual perceptions, and its impact on initiation and persistence of bullying. The specific research question, “How does the need to conform with peers and the peer group influence the initiation and persistence of bullying others?” is investigated. Semistructured, one-on-one interviews with a purposive sample of 51 Grade 7 students (aged 12 years) were conducted during school time to investigate factors that influence students to bully others and what might help them to stop. Emerging from the theme of peer group was the need for belonging and group status, in particular social norms or the need to conform, which was influential when students described why they initiated and persisted with bullying others. The influence of labeling, the group process, and the aspiration to be like others within their group emerged as key constructs. The implications of these data for schools will be described and recommendations made.

Prostate cancer (PrCA) is the most commonly diagnosed nonskin cancer among men. African American (AA) men in South Carolina have a PrCA death rate 150% higher than that of European American (EA) men. This in-depth qualitative research explored AA men’s and women’s current practices, barriers, and recommended strategies for PrCA communication. A purposive sample of 43 AA men and 38 AA spouses/female relatives participated in focus groups (11 male groups; 11 female groups). A 19-item discussion guide was developed. Coding and analyses were driven by the data; recurrent themes within and across groups were examined. Findings revealed AA men and women agreed on key barriers to discussing PrCA; however, they had differing perspectives on which of these were most important. Findings indicate that including AA women in PrCA research and education is needed to address barriers preventing AA men from effectively communicating about PrCA risk and screening with family and health care providers.

Risk Categories

Purpose – The purpose of this paper is to identify the risks faced by users of online social networking services (SNSs) in the UK and to develop a typology of risk that can be used to assess regulatory effectiveness. Design/methodology/approach – An initial investigation of the literature revealed no detailed taxonomies of risk in this area. Existing taxonomies were reviewed and merged with categories identified in a pilot survey and expanded in purposive sample survey directed at the library and information services (LIS) community in the UK. Findings – Analysis of the relationships between different risk categories yielded a grouping of risks by their consequences. This aligns with one of the objectives of regulation, which is to mitigate risks. Research limitations/implications – This research offers a tool for evaluation of different modes of regulation of social media. Practical implications – Awareness of the risks associated with use of online SNSs and wider social media contributes to the work of LIS professionals in their roles as: educators; intermediaries; and users of social media. An understanding of risk also informs the work of policy makers and legislators responsible for regulating access to personal data. Originality/value – A risk-based view of regulation of personal data on social media has not been attempted in such a comprehensive way before.
