The influence of trade union Disability Champions on employer disability policy and practice
Disability Champions are a new type of lay workplace trade union activist, whose role is to encourage employers to audit and improve disability policies and offer independent advice and guidance on disability issues to employees. Drawing on a survey of the population of Disability Champions, this article assesses Disability Champion influence on employer disability policy and practice. While the majority of Disability Champions report having had a positive impact, they report greater influence on employer willingness to conduct disability audits and to amend and improve employer equal opportunities practices with regard to disability than employer willingness to make reasonable adjustments. The analysis also identifies several factors that are likely to be important in improving Disability Champion effectiveness. Overall, the results suggest Disability Champions have the potential to enhance the ability of unions to represent disabled people and help manage disability issues within the workplace. The article makes a theoretical contribution to Disability Champion roles by further developing the ‘Activity-Support-Characteristic’ framework for the antecedents of new union representatives' effectiveness

Workplace union representation in the British public sector: evidence from the 2011 Workplace Employment Relations Survey.
This paper explores the presence of workplace union representatives in the British public sector, and also the extent to which union representatives are engaged in partnership working with management, drawing on data from the Workplace Employment Relations Survey 2011. This analysis is timely given government plans to introduce reporting requirements and reserve powers to restrict public sector facility time in the Trade Union Bill 2015-16. The analysis finds that in workplaces with union recognition, union representatives are more prevalent and there are more representatives per employee in the public than the private sector, but there is no evidence that this should be viewed as excessive or that managers view it as problematic. There is, on balance, greater evidence of partnership working between union representatives and managers in the public than the private sector. Given the importance of partnership working in improving public services, the results suggest the provisions in the Trade Union Bill 2015-16 relating to public sector facility time are more likely to hinder rather than support public sector managers in their attempts to improve public service provision in the future
Saving Energy in Mobile Devices for On-Demand Multimedia Streaming -- A Cross-Layer Approach
This paper proposes a novel energy-efficient multimedia delivery system
called EStreamer. First, we study the relationship between buffer size at the
client, burst-shaped TCP-based multimedia traffic, and energy consumption of
wireless network interfaces in smartphones. Based on the study, we design and
implement EStreamer for constant bit rate and rate-adaptive streaming.
EStreamer can improve battery lifetime by 3x, 1.5x and 2x while streaming over
Wi-Fi, 3G and 4G respectively.Comment: Accepted in ACM Transactions on Multimedia Computing, Communications

Effect of photoperiod and temperature on ovarian cycle of the frog Rana tigrina (Daud.)
The effect of varying photoperiod regimes (LD: 20,4; 4,20; 6,18; 18,6 and 12,12) on ovarian follicular development was analysed in the frogRana tigrina maintained at ambient and constant 30° ± l° C for 3 months. The experiments were conducted in early recrudescent and quiescent phases. The frogs were fed guppiesad libitum on alternate day. None of the photoperiod regimes had any effect on the ovaries or the fat bodies, whereas exposure to constant high temperature (regardless of photoperiod) during recrudescent phase induced production of greater number of eggs (~ 18000 vs 13000 in controls) of ovulatory sizes (> 1400µm) compared to the corresponding controls maintained at ambient temperature. Hence, ovarian mass also increased in these frogs. In the quiescent phase, high temperature merely enhanced growth of previtellogenic oocytes. In both the phases high temperature caused a reduction in the fat bodies over the respective controls, possibly due to increased metabolic activity. The above findings indicate that temperature plays a key role in the regulation of ovarian cycle ofRana tigrina and that the photoperiodic mechanisms may not govern the annual recrudescence of ovaries in the frog. The study also shows that the frog exhibits the phenomenon of "phenotypic plasticity" in its reproductive behaviour by producing significantly greater number of eggs in response to elevated temperature
