The use of mobile devices, especially smartphones, is widespread across all social strata and age groups, helping to ensure faster access from anywhere, data collection, and more regular and frequent control to aid urban, environmental, and social management. In this scenario, the entertainment industry has benefited from this powerful individual technological resource in cultural and sporting events. In this way, this work presents a proposal for interaction and engagement in entertainment events in a more prosperous and more technological way, through the development of a collaborative and competitive mobile-­web crowd game, intended for enhancing interaction between the crowd and as a unified group, whether physically co-­located or online. The application, called Bumbometer, uses motion sensors during an interactive dynamic with the crowd applying concepts from Mobile Crowd Sensing and User eXperience. We conducted two experimental studies to evaluate the proposed technology, the first in a real scenario of a folk cultural festival and the second in a controlled environment, simulating an event considering a scenario in which users were geographically distant. The results indicate that people feel immersed and engaged during the interaction through the proposed game, which reinforces the statement that the game meets an increasingly growing need to use technologies to ensure more significant interaction and audience immersion at crowd entertainment events, a creative and far­-reaching form.

ObjectivesGiven the exponential increase in the use of e-cigarettes among younger age groups and in the growth in research on e-cigarette flavours, we conducted a systematic review examining the impact of non-menthol flavoured e-cigarettes on e-cigarette perceptions and use among youth and adults.DesignPubMed, Embase, PyscINFO and CINAHL were systematically searched for studies published and indexed through March 2018.Eligibility criteriaQuantitative observational and experimental studies that assessed the effect of non-menthol flavours in e-cigarettes on perceptions and use behaviours were included. Specific outcome measures assessed are appeal, reasons for use, risk perceptions, susceptibility, intention to try, initiation, preference, current use, quit intentions and cessation.Data extraction and synthesisThree authors independently extracted data related to the impact of flavours in tobacco products. Data from a previous review were then combined with those from the updated review for final analysis. Results were then grouped and analysed by outcome measure.ResultsThe review included 51 articles for synthesis, including 17 published up to 2016 and an additional 34 published between 2016 and 2018. Results indicate that non-menthol flavours in e-cigarettes decrease harm perceptions (five studies) and increase willingness to try and initiation of e-cigarettes (six studies). Among adults, e-cigarette flavours increase product appeal (seven studies) and are a primary reason many adults use the product (five studies). The role of flavoured e-cigarettes on smoking cessation remains unclear (six studies).ConclusionThis review provides summary data on the role of non-menthol flavours in e-cigarette perceptions and use. Consistent evidence shows that flavours attract both youth and adults to use e-cigarettes. Given the clear findings that such flavours increase product appeal, willingness to try and initiation among youth, banning non-menthol flavours in e-cigarettes may reduce youth e-cigarette use. Longitudinal research is needed to examine any role flavours may play in quit behaviours among adults.

Abstract Social outings can trigger influenza transmission, especially in children and elderly. In contrast, school closures are associated with reduced influenza incidence in school-aged children. While influenza surveillance modelling studies typically account for holidays and mass gatherings, age-specific effects of school breaks, sporting events and commonly celebrated observances are not fully explored. We examined the impact of school holidays, social events and religious observances for six age groups (all ages, ⩽4, 5–24, 25–44, 45–64, ⩾65 years) on four influenza outcomes (tests, positives, influenza A and influenza B) as reported by the City of Milwaukee Health Department Laboratory, Milwaukee, Wisconsin from 2004 to 2009. We characterised holiday effects by analysing average weekly counts in negative binomial regression models controlling for weather and seasonal incidence fluctuations. We estimated age-specific annual peak timing and compared influenza outcomes before, during and after school breaks. During the 118 university holiday weeks, average weekly tests were lower than in 140 school term weeks (5.93 vs. 11.99 cases/week, P < 0.005). The dampening of tests during Winter Break was evident in all ages and in those 5–24 years (RR = 0.31; 95% CI 0.22–0.41 vs. RR = 0.14; 95% CI 0.09–0.22, respectively). A significant increase in tests was observed during Spring Break in 45–64 years old adults (RR = 2.12; 95% CI 1.14–3.96). Milwaukee Public Schools holiday breaks showed similar amplification and dampening effects. Overall, calendar effects depend on the proximity and alignment of an individual holiday to age-specific and influenza outcome-specific peak timing. Better quantification of individual holiday effects, tailored to specific age groups, should improve influenza prevention measures.

Purpose – The purpose of this study is to assess, in two different live sponsorship environments, the contribution of sponsorship to consumer-based brand equity. Design/methodology/approach – The study adopts a quantitative survey methodology, employing self-administered questionnaires at two UK sporting events (athletics and cricket). To isolate the impact of sponsorship, questionnaires were also distributed to comparison sample groups not exposed to the sponsorship activities. The elements of consumer-based brand equity are operationalized in line with Aaker's (1996) brand equity measurement tool. Findings – Sponsorship can be an appropriate vehicle through which to build consumer-based brand equity; however brand-building success is not guaranteed and is subject to a range of factors impacting upon particular sponsorships, including strength of the sponsor-event link, leverage activities and clutter. The most successful sponsorship displayed marked contributions to building brand associations, perceived quality and brand loyalty. However, the presence of sponsorship clutter in particular was found to impact negatively upon the perception of quality transferred to a brand through sponsorship. Research limitations/implications – The use of live event settings limits the ability to tightly control all variables; therefore replication of this study using experimental methodologies is recommended. Nonetheless, findings indicate managers should consider the above mentioned contextual factors when selecting sponsorships in order to maximize sponsorship success. Originality/value – This study explores the contribution of sports sponsorship to consumer-based brand equity in live sponsorship settings, addressing concerns over the generalizability of previous experimental studies. Equally, this study compares the brand equity-building effectiveness of sponsorship for two sponsors, which differ on a range of contextual factors that impact upon sponsorship success.

Eating disorders are widespread illnesses with significant impact. There is growing concern about how those at risk of eating disorders overuse online resources to their detriment. We conducted a pre-registered systematic review and meta-analysis of studies examining Problematic Usage of the Internet (PUI) and eating disorders. The meta-analysis comprised n=32,295 participants, in which PUI was correlated with significant eating disorder psychopathology Pearson r=0.22 (s.e.=0.04, p<0.001), body dissatisfaction r=0.16 (s.e.=0.02, p<0.001), drive-for-thinness r=0.16 (s.e.=0.04, p<0.001) and dietary restraint r=0.18 (s.e.=0.03). Effects were not moderated by gender, PUI facet or study quality. Results are in support of PUI impacting significantly on vulnerable populations towards the development or maintenance of eating disorder psychopathology; males may be equally vulnerable to these potential effects. Prospective and experimental studies in the field suggest that small but significant effects exist and may have accumulative influence over time and across all age groups. Those findings are important to expand our understanding of PUI as a multifaceted concept and its impact on multiple levels of ascertainment of eating disorder psychopathology.

The article is devoted to the description of experimental studies of the possibility of increasing the energy efficiency of the lighting installation (LI) through the use of motion sensors. Data on possible energy savings are needed to conduct economic calculations – to estimate the payback period of capital costs for the implementation of a lighting control system (LCS). A quantitative and qualitative assessment of the economic feasibility of creating or developing an LCS is based on calculating and analyzing the costs required for its implementation and comparing the costs with the results obtained during its implementation. The results of the functioning of the LCS can be expressed by such a value as the percentage of possible energy savings, expressed in terms of the ratio of electricity consumption after the introduction of the LCS to the consumption of electricity before its implementation. In this work, this coefficient was determined experimentally. The experiment was carried out in public building – in the laboratory and educational building of the university. A corridor of one of the floors was chosen as the object of the study. For the research, a data collection system based on a digital microcontroller was used; infrared motion sensors were usedas presence sensors. The results of the experiment showed that the presence of people in the corridor varies during the day, by days of the week, from month to month. Studies have shown that, on average, energy savings when using motion sensors in the on / off mode of lamps is at least 50 %. With an increase in the delay time for turning off the luminaires after the motion sensor is triggered, the energy saving decreases from 66.5 % to 48.5 %. When using the standby lighting mode during the absence of people, the savings are reduced from 66.5 % (with the lamps turned off due to lack of movement) to 21.9 %.

AbstractAccurate knowledge of pathogen incubation period is essential to inform public health policies and implement interventions that contribute to the reduction of burden of disease. The incubation period distribution of campylobacteriosis is currently unknown with several sources reporting different times. Variation in the distribution could be expected due to host, transmission vehicle, and organism characteristics, however, the extent of this variation and influencing factors are unclear. The authors have undertaken a systematic review of published literature of outbreak studies with well-defined point source exposures and human experimental studies to estimate the distribution of incubation period and also identify and explain the variation in the distribution between studies. We tested for heterogeneity using I2 and Kolmogorov–Smirnov tests, regressed incubation period against possible explanatory factors, and used hierarchical clustering analysis to define subgroups of studies without evidence of heterogeneity. The mean incubation period of subgroups ranged from 2·5 to 4·3 days. We observed variation in the distribution of incubation period between studies that was not due to chance. A significant association between the mean incubation period and age distribution was observed with outbreaks involving only children reporting an incubation of 1·29 days longer when compared with outbreaks involving other age groups.

The mean density of fat-free mass (FFM) is remarkably stable at 1.10 g/cm3 in healthy adult humans, and this stability is a cornerstone of the widely applied densitometry-based two-compartment model for estimating total body fat. At present, the usual means of exploring FFM density is by in vitro or in vivo experimental studies. The purpose of the present investigation was to develop a cellular-level body composition model that includes seven factors that determine FFM density. The model, when applied with available empirical coefficients, predicted an FFM density similar to that observed in vivo. An analysis of the seven model components indicates that the ratio of extracellular solids to total body water is a major determinant of individual variation in FFM density. The difference in FFM density across sex, race, and age groups was examined with the developed model. The present study thus provides a conceptual framework for the systematic study of FFM density in humans.
