MiPOS - the Mote Indoor Positioning System
In the past few years, there have been huge research efforts into ubiquitous and context aware platforms that offer a user a custom level of service based on some known local parameters. The utility of such systems is greatly enhanced if a physical locational area can be determined. Recently, hybrid devices have been developed combining low power micro controllers with short range FM radio transceivers. Some location identification work has been carried out with these systems such as the Matrix Pencil approximation technique[8],however most of these all provide information for an ideal square area with no RF obstructions.Here we present MiPOS, a scalable locationing system based on the MICA mote[11] family of devices.The design goal of MiPOS is to provide a low-power, scalable, distributed locationing system suited to an indoor (office) environment.During the presentation of this paper we will highlight solutions in the areas of security, radio and network management and power awareness for a hybrid context aware wearable locationing device
Determining the Efficacy of Mental Health Awareness Interventions in Sport Using a Systematic Review
Evolving innovation through office knowledge networks : mapping the ephemeral architecture of organizational creativity
This paper explores positive conditions for the evolution of creative innovation through informal social networks in the office. By drawing on both Social Network Analysis (SNA)
and the abstracted evolutionary mechanisms of variation, selection and retention, a multilevel conceptualization of the evolutionary processes underpinning the emergence and
development of ideas within an organization is put forward. In this way SNA is used to visualize not just the connectivity of individuals within the company who offer 'expert advice' and 'new ideas' in the development of these products, but also the role of mediators in this
process at a digital media company, Dataco
Psychometric Assessment of the Mental Health Continuum-Short Form in Athletes: a Bi-factor Modelling Approach
: Frequency, Intensity and Duration of Muscle Strengthening Activity and Associations with Mental Health
Objectives: Despite growing emphasis on the benefits of physical activity for promoting mental health, inclusion of muscle-strengthening (MS) (e.g., body-weight exercises, resistance machines) activities is limited. Notably, few studies collectively assess MS behavioural frequency, duration, and intensity. To address the gap, the current study examined associations between frequency (days), intensity (rating of perceived exertion in relation to repetitions in reserve [RPE/RIR]), and duration (minutes per typical session) of MS activities on anxiety, depression, and mental well-being.Method: A cross-sectional study of 601 participants (Mean age = 30.92 years [SD =12.70]; 57.7% female) across Ireland was conducted. Participants completed a self-report questionnaire containing MS instruments previously used, or adapted from valid and reliable measures (i.e., International Physical Activity Questionnaire IPAQ, RPE/RIR), alongside, the Generalised Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-8 (PHQ-8) and the Mental Health Continuum- Short Form (MHC-SF). A multivariate regression model was tested in MPLUS, using dummy coding for MS frequency in relation to no activity (i.e., 0-days) non-adherence (i.e., 1-day), adherence (i.e., 2-days) and enhanced adherence (i.e., >3 days) to the MS public health guidelines, with the mental health variables representing the dependent variables. Intensity and duration were specified in the model as continuous variables; gender and age were included as statistical controls. Results: Three or more days engaged in MS activities was associated with fewer anxiety (β = -.12, p Conclusion: Higher frequency and intensity of MS activities may protect against anxiety and depression symptoms. Doing some MS activities (at least 1-day) is likely more beneficial than none for depression. Evidence-based, MS interventions may help curb mental illness rates, and future longitudinal, intervention-based research could consider inclusion of MS frequency, intensity and duration variables to enhance efforts to identify at-risk groups and trends within physical activity and mental illness surveillance.<br/
The Influence of Athletes’ Psychological Needs on Motivation, Burnout and Well-Being: a Test of Self-Determination Theory
Sport provides a significant role in the lives of athletes, however both positive and negative mental health effects may occur from sporting experiences, including burnout and/or well-being. A cross-sectional survey was conducted including 685 athletes (M age = 23.39, SD = 6.22, 71% = male), testing multiple, complementary, Self-Determination Theory (SDT) hypotheses linked to well-being and burnout. A multi-stage modelling approach encompassing confirmatory factor and path analysis was utilised, with results showing significant variance explained for well-being (R2=.30) and burnout (R2=.35). Several direct effects were found in line with SDT, including between; needs-support and needs satisfaction (β= .48), and needs-control and needs-frustration (β= .44); needs-satisfaction and motivational orientation (β= .25); needs-satisfaction and well-being (β= .37), and needs frustration and burnout (β= .25); motivational orientation and burnout (β= -.27), and motivational orientation and well-being (β= .18). Indirect effects were found for well-being and burnout via coach needs-support, needs satisfaction and motivational orientation in sequence (β=.24 and β=-.22, respectively); in addition to burnout via coach needs-control, needs frustration and motivational orientation in sequence (β=-.12). To conclude, coach-based, sporting mental health interventions that promote the utilisation of needs-supportive behaviours, whilst also highlighting the need to minimise needs-controlling behaviours, are recommended for the prevention of burnout and promotion of well-being in athletes
Comparing Mental Health of Athletes and Non-Athletes as they Emerge from a COVID-19 Pandemic Lockdown
Athletes going through transition periods such as injury or retirement have previously reported feelings of depression and anxiety, especially when feeling unsupported. Cessation of competitive sport during the pandemic has forced athletes through a non-normative transition and has reduced many opportunities to satisfy their basic psychological needs increasing the risk of poor wellbeing and loneliness. Whilst athletes are often praised for their resilience—a trait that serves to support them during tough times—the inability to play sport can be particularly challenging for those with strong athletic identities. An online cross-sectional survey (n = 744) was conducted to capture adult athlete and non-athlete mental health factors (specifically wellbeing, depression, anxiety, loneliness) during emergence from a COVID-19 lockdown. Results showed that resilience was positively correlated with mental health but was no higher in athletes than non-athletes. Furthermore, athletes reported greater anxiety than non-athletes, a difference mediated by negative affectivity—a subfactor of athletic identity. We present evidence that after a temporary transition away from sport, athletes' resilience is comparable to non-athletes leaving them just as likely to suffer poor mental health. Moreover, athletes with strong athletic identities are likely to experience anxiety symptoms above and beyond those reported by non-athletes. Findings have implications for the development of self-management guidance for athletes as the COVID-19 pandemic and restrictions on sport participation continue
Adolescent Mental Health Help-Seeking from Family and Doctors:Applying the Theory of Planned Behaviour to the Northern Ireland Schools and Wellbeing Study
Testing the psychometric properties of Kidscreen-27 with Irish children of low socio-economic status
BACKGROUND: Kidscreen-27 was developed as part of a cross-cultural European Union-funded project to standardise the measurement of children’s health-related quality of life. Yet, research has reported mixed evidence for the hypothesised 5-factor model, and no confirmatory factor analysis (CFA) has been conducted on the instrument with children of low socio-economic status (SES) across Ireland (Northern and Republic). METHOD: The data for this study were collected as part of a clustered randomised controlled trial. A total of 663 (347 male, 315 female) 8–9-year-old children (M = 8.74, SD = .50) of low SES took part. A 5- and modified 7-factor CFA models were specified using the maximum likelihood estimation. A nested Chi-square difference test was conducted to compare the fit of the models. Internal consistency and floor and ceiling effects were also examined. RESULTS: CFA found that the hypothesised 5-factor model was an unacceptable fit. However, the modified 7-factor model was supported. A nested Chi-square difference test confirmed that the fit of the 7-factor model was significantly better than that of the 5-factor model. Internal consistency was unacceptable for just one scale. Ceiling effects were present in all but one of the factors. CONCLUSIONS: Future research should apply the 7-factor model with children of low socio-economic status. Such efforts would help monitor the health status of the population
