    Multimodal biometrics are promising for providing a strong security level for personal authentication, yet the implementation of a multimodal biometric system for practical usage need to meet such criteria that multimodal biometric signals should be easy to acquire but not easily compromised. We developed a wearable wrist band integrated with multispectral skin photomatrix (MSP) and electrocardiogram (ECG) sensors to improve the issues of collectability, performance and circumvention of multimodal biometric authentication. The band was designed to ensure collectability by sensing both MSP and ECG easily and to achieve high authentication performance with low computation, efficient memory usage, and relatively fast response. Acquisition of MSP and ECG using contact-based sensors could also prevent remote access to personal data. Personal authentication with multimodal biometrics using the integrated wearable wrist band was evaluated in 150 subjects and resulted in 0.2% equal error rate ( EER ) and 100% detection probability at 1% FAR (false acceptance rate) ( PD.1 ), which is comparable to other state-of-the-art multimodal biometrics. An additional investigation with a separate MSP sensor, which enhanced contact with the skin, along with ECG reached 0.1% EER and 100% PD.1 , showing a great potential of our in-house wearable band for practical applications. The results of this study demonstrate that our newly developed wearable wrist band may provide a reliable and easy-to-use multimodal biometric solution for personal authentication

    Neoliberalisation and 'lad cultures' in higher education

    This paper links HE neoliberalisation and ā€˜lad culturesā€™, drawing on interviews and focus groups with women students. We argue that retro-sexist ā€˜laddishā€™ forms of masculine competitiveness and misogyny have been reshaped by neoliberal rationalities to become modes of consumerist sexualised audit. We also suggest that neoliberal frameworks scaffold an individualistic and adversarial culture among young people that interacts with perceived threats to menā€™s privilege and intensifies attempts to put women in their place through misogyny and sexual harassment. Furthermore, ā€˜lad culturesā€™, sexism and sexual harassment in higher education may be invisibilised by institutions to preserve marketability in a neoliberal context. In response, we ask if we might foster dialogue and partnership between feminist and anti-marketisation politics

    Ā© 2017 National Strength and Conditioning Association. The aim of the study was to determine the between-session reliability of isometric midthigh pull (IMTP) kinetics and maximal weight lifted during the power clean (PC) in male youth soccer players, and to identify the smallest detectable differences between sessions. Thirteen male youth soccer players (age: 16.7 Ā± 0.5 years, height: 1.80 Ā± 0.08 m, and mass: 70.5 Ā± 9.4 kg) performed 3 IMTP trials, whereas only 10 soccer players performed maximal PCs. These were performed twice, separated by 48 hours to examine the between-session reliability. Intraclass correlation coefficients (ICCs) and coefficient of variation (CV) demonstrated high levels of within-session (ICC = 0.84ā€“0.98, CV = 4.05ā€“10.00%) and between-session reliability (ICC = 0.86ā€“0.96, CV = 3.76ā€“7.87%) for IMTP kinetics (peak force [PF] and time-specific force values 30ā€“250 ms) and maximal PC (ICC = 0.96, CV = 3.23%), all meeting minimum acceptable reliability criteria. No significant differences (p > 0.05, effect size ā‰¤0.22) were revealed between sessions for IMTP kinetics and maximal PC performance. Strength and conditioning coaches and practitioners should consider changes of >6.04% in maximal PC and changes in IMTP kinetics of >14.31% in force at 30 ms, >14.73% in force at 50 ms, >12.36% in force at 90 ms, >12.37% in force at 100 ms, >14.51% in force at 150 ms, >11.71% in force at 200 ms, >7.23% in force at 250 ms, and >8.50% in absolute PF as meaningful improvements in male youth soccer players. Decrements in the IMTP kinetics greater than the aforementioned values could possibly be used as an indicator of neuromuscular fatigue and preparedness for training or competition

    Cytotoxic chemotherapy for incurable colorectal cancer: living with a PICC-line

    <b>Aims.</b> (i) To determine which aspects of living with a peripherally inserted central catheter (PICC) line cause Modified de Gramont (MdG) patients most difficulty. (ii) To explore MdG patients' views of the PICC-line experience. (iii) To determine if patients view PICC-lines as a benefit or a burden when receiving ambulatory MdG chemotherapy. <b>Design.</b> A two-stage, descriptive study. <b>Methods.</b> Phase 1 comprised semi-structured interviews. Phase 2 surveyed the MdG population. Phase 1 interview data informed the Phase 2 questionnaire. The setting was a West of Scotland Cancer Care Centre and the sample was: Phase 1, a convenience sample of 10 MdG patients; Phase 2, 62 consecutive patients. <b>Results.</b> A response rate of 93Ā·9% for Phase 2. The majority of PICC-line patients held favourable views towards having a PICC-line and adapted well with minimal disruption to daily life. Concerns were evident regarding coping at home with a PICC-line, chemotherapy spillage, dealing with complex information and the responsibility of patients/carers regarding PICC-line management. Patients preferred ambulatory chemotherapy to in-patient treatment. <b>Conclusions.</b> PICC-lines should be considered for more chemotherapy patients but service development is necessary to ensure individual needs are addressed. <b>Relevance to clinical practice.</b> Contributes to the PICC-line literature by providing a national patient perspective on a range of daily living activities (DLAs). PICC-line patients prefer out-patient ambulatory chemotherapy rather than in-patient treatment. The longer a patient has a PICC-line, the more able they are to manage activities such as dressing. Concerns remain over chemotherapy spillage, partner/carer responsibility for PICC-line maintenance and the proper balance between required information and what the patient wants to know

    Managing and monitoring equality and diversity in UK sport: An evaluation of the sporting equals Racial Equality Standard and its impact on organizational change

    Get PDF
    Despite greater attention to racial equality in sport in recent years, the progress of national sports organizations toward creating equality of outcomes has been limited in the United Kingdom. The collaboration of the national sports agencies, equity organizations and national sports organizations (including national governing bodies of sport) has focused on Equality Standards. The authors revisit an earlier impact study of the Racial Equality Standard in sport and supplement it with another round of interview material to assess changing strategies to manage diversity in British sport. In particular, it tracks the impact on organizational commitment to diversity through the period of the establishment of the Racial Equality Standard and its replacement by an Equality Standard that deals with other diversity issues alongside race and ethnicity. As a result, the authors question whether the new, generic Equality Standard is capable of addressing racial diversity and promoting equality of outcomes. Ā© 2006 Sage Publications
