The tablet computer offers options for streaming TV programming that potentially alters viewing behaviors compared to the traditional television set, yet there is a dearth of research related to this viewing alternative. This study uses a national sample of adult iPad owners to investigate the tablet's role as a TV. The frameworks of continuity-discontinuity, use-diffusion, and attention and absorption to programming are applied to uncover where the tablet fits into the current repertoire of viewing devices, and how individuals are engaging with traditional TV programming through it. Results show that overall, the tablet's functionality as a TV can lead to experiential differences. 相似文献

AIM: To assess the incidence and nature of concerns about sexual abuse, with particular reference to erroneous concerns of sexual abuse made by children. METHODS: A review of case notes of all child sexual abuse reports to the Denver Department of Social Services over 12 months. Cases were put into four groups: substantiated, not sexual abuse, inconclusive and erroneous accounts by children. RESULTS: 551 cases were reviewed. Forty-three percent were substantiated, 21% were inconclusive and 34% were not considered to be abuse cases. There were 14 (2.5%) erroneous concerns emanating from children. They comprised three cases of allegations made in collusion with a parent, three cases where an innocent event was misinterpreted as sexual abuse and eight cases (1.5%) of false allegations of sexual abuse.CONCLUSION: Erroneous concern of sexual abuse from children are uncommon. The four categories of concern in this study, in contrast to the simple classification of substantiated and unsubstantiated, provide a means of encouraging open minded assessments of the typical concerns which a child protection agency receives. 相似文献

The present research combines in-depth interviews and in-home observations to explore usage patterns and perceptions of television viewers in digital video recorder (DVR) households. Innovativeness, Use Diffusion, and Continuity-Discontinuity are employed to characterize DVR use and conceptualize DVR viewing in the home. Findings indicate that the DVR is an important, interactive technology that can help transform the way television is used by some consumers in their movement to proactive media decision makers. 相似文献

The aim of this study was to develop an exercise protocol to simulate tennis matchplay on a 'category 2' surface. Match analyses were used to form the basis for the design of the protocol. The protocol involved playing against a tennis ball serving machine. Part A of the protocol comprised 92 min 46 s of simulated tennis matchplay; Part B consisted of continuous hitting to the point of 'volitional fatigue' or when the required hitting frequency for two consecutive ball feeds could no longer be maintained. Ten elite tennis players (5 males, 5 females) volunteered to participate in the study, which was performed on an indoor tennis court (Matchplay?, En-Tout-Cas)?. Their age, body mass and estimated maximal oxygen uptake were as follows: males, 21.7±1.0 years, 73.6±2.6 kg and 58.0±1.7 ml?·?kg?1?·?min?1, respectively; females, 21.9±1.3 years, 62.3±2.0 kg and 42.2±0.7 ml?·?kg?·?min?1, respectively (mean±). Heart rate, change in body mass and time to volitional fatigue were monitored. The heart rate responses of the participants to the simulated matchplay (range: 140-157 beats?·?min?1, 73-81% peak heart rate) were consistent with the results of previous studies, for 'actual' matchplay. This protocol was successful in simulating similar physiological responses in Part A to 'actual' matchplay on a 'category 2' surface, in a controlled environment; it was also a sensitive evaluation tool of skilled performance in Part B. The current protocol may be used as a baseline protocol for studying the influence of, for example, training and dietary intervention on performance. 相似文献
