The aim of this integrative review was to describe the organisational, unregulated nurse, and resident outcomes associated with effective supervisory performance of regulated nurses (registered nurses or registered practical nurses) in long-term care homes.While there are data on the influence of regulated nurse staffing levels on resident outcomes, the influence of effective supervisory performance of regulated nurses on resident and organisational outcomes, nursing assistant outcomes have yet to be comprehensively explored.A search of six databases was made for articles dating from 2000 to 2015. Twenty-four articles were selected and an integrative review was performed.Effective nurse supervision had statistically significant positive associations (P<0.05, P<0.000) with six different organisational, unregulated nurse and resident outcomes: nurse assistant job satisfaction, turnover/intention to leave, effectiveness, decision making, job stress and consumer satisfaction. Qualitative analyses corroborate these findings.There appear to be some associations between effective supervisory performance of regulated nurses with positive organisational, unregulated nursing and resident outcomes.Nursing managers and leaders in long-term care may promote improvements in effective nurse supervision performance as a way of reducing turnover and improving resident outcomes.

Blockchain represents a technology for establishing a shared, immutable version of the truth between a network of participants that do not trust one another, and therefore has the potential to disrupt any financial or other industries that rely on third-parties to establish trust. In order to better understand the current ecosystem of Blockchain applications, a scalable proofof-concept pipeline for analysis of multiple streams of semistructured data posted on social media is demonstrated, based on open source components. Deep Web as well as conventional social media are considered. Preliminary analysis suggests that data found in the Deep Web is complimentary to that available on the conventional web. Future work is described that will scale the system to cloud-based, real-Time, analysis of multiple data streams, with Information Extraction (IE) (ex. sentiment analysis) and Machine Learning capability. © 2016 IEEE.

During embryonic development, regulation of gene expression is key to creating the many subtypes of cells that an organism needs throughout its lifetime. Recent work has shown that maternal genetics and environmental factors have lifelong consequences on diverse processes ranging from immune function to stress responses. The RE1-silencing transcription factor (Rest) is a transcriptional repressor that interacts with chromatin-modifying complexes to repress transcription of neural-specific genes during early development. Here we show that in zebrafish, maternally supplied rest regulates expression of target genes during larval development and has lifelong impacts on behavior. Larvae deprived of maternal rest are hyperactive and show atypical spatial preferences. Adult male fish deprived of maternal rest present with atypical spatial preferences in a novel environment assay. Transcriptome sequencing revealed 158 genes that are repressed by maternal rest in blastula stage embryos. Furthermore,wefound that maternal rest is required for target gene repression until at least 6 dpf. Importantly, disruption of the RE1 sites in either snap25a or snap25b resulted in behaviors that recapitulate the hyperactivity phenotype caused by absence of maternal rest. Both maternal rest mutants and snap25a RE1 site mutants have altered primary motor neuron architecture that may account for the enhanced locomotor activity. These results demonstrate that maternal rest represses snap25a/b to modulate larval behavior and that early Rest activity has lifelong behavioral impacts. © 2016 the authors.

Through matches with the Sloan Digital Sky Survey (SDSS) catalogue we identify the location of various families of astronomical objects in WISE colour space.We identify reliable indicators that separate Galactic/local from extragalactic sources and concentrate here on the objects in our Galaxy and its closest satellites. We develop colour and magnitude criteria that are based only on WISE data to select asymptotic giant branch (AGB) stars with circumstellar dust shells, and separate them into O-rich and C-rich classes. With these criteria we produce an all-sky map for the count ratio of the two populations. The map reveals differences between the Galactic disc, the Magellanic Clouds and the Sgr Dwarf Spheroidal galaxy, as well as a radial gradient in the Large Magellanic Cloud (LMC) disc. We find that the C:O number ratio for dusty AGB stars increases with distance from the LMC centre about twice as fast as measured for near-IR selected samples of early AGB stars. Detailed radiative transfer models show that WISE colours are well explained by the emission of centrally heated dusty shells where the dust has standard properties of interstellar medium (ISM) grains. The segregation of different classes of objects in WISE colour space arises from differences in properties of the dust shells: those around young stellar objects have uniform density distributions while in evolved stars they have steep radial profiles. © 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

Objectives: Given the tendency for young people to show elevated work injury rates, this study sought to examine trends in young worker and adult compensation claim rates in a Canadian province. Methods: Workers' compensation records and labour force survey data from 1991 to 2007 were used to compute claim rates by age group. To examine the contribution of work-related factors to claim rates by age group, multivariate analyses included industry and job tenure. Results: Descriptive analysis showed that age groups had different rates of declines over the time period. Multivariate analyses showed that claim rate declines for older adults were greatest prior to 1999. Young workers showed the largest declines after 1999. There was no indication that changes in industry or job tenure accounted for the trends in claim rates among older or younger workers. Conclusions: This study is one of the first to show a convergence in youth and adult workers' compensation claims in a North American jurisdiction. Ruling out work-related factors increases the possibility that systemic interventions may have contributed to the convergence. This provides policy makers in occupational health and safety with empirical data to guide targeting of resources.

Progress in Transplantation | Year: 2011
Context-Adolescents are at higher risk for organ loss than are all other age groups, but no studies have been conducted to examine the specific information needs of adolescents. A better understanding of adolescents' information needs is essential for developing programs tailored to their unique requirements.Objective-To explore information needs of adolescents who have undergone kidney transplantation in order to inform development of an education program.Design-A qualitative descriptive design was used. Focus groups (n = 2) were conducted by using a semistructured interview guide. Transcribed data were organized into categories that reflected emerging themes by using simple content analysis.Participants and Setting-A convenience sample of 8 adolescents (50% female) who varied in age, donor type, and time since transplantation were recruited from a large Canadian tertiary care pediatric center.Results- Adolescents articulated that the process of undergoing kidney transplant was very stressful and affected all aspects of their lives. In particular, adolescents identified 4 main stressors: changes in body image, wanting to be normal, pain, and breakdown in communication processes. The 2 strategies that assisted adolescents in coping with these stressors were (1) gaining knowledge about the transplantation process and (2) experiencing understanding through social support. They wanted information provided to them gradually throughout the transplant experience with choices given as to how they receive the information.Conclusion-Adolescents were united in their call for information, self-management strategies, and meaningful social support to better manage their kidney transplant and prepare for transition to adult health care.

In this work we (i) expose and analyse the social-psychological principle of commitment and consistency embedded in the Extreme Programming software development process, (ii) illustrate how this principle can be leveraged to impact upon project success, and (iii) provide practical evidence of the manifestation of this principle and its effects in the Extreme Programming domain, through nascent results from our qualitative case study. This work is in its initial stages; our intent is to persuade the reader that commitment and consistency are indeed relevant factors in Extreme Programming process, are potentially impactful on organizational success, and are worthy of further study.

The Hardy–Weinberg equilibrium has been argued by Sober, Stephens and others to represent the zero-force state for evolutionary biology understood as a theory of forces. I investigate what it means for a model to involve forces, developing an explicit account by defining what the zero-force state is in a general theoretical context. I use this account to show that Hardy–Weinberg equilibrium is not the zero-force state in biology even in the contexts in which it applies, and argue based on this that drift should not be understood as an evolutionary force. © 2014, Springer Science+Business Media Dordrecht.

Cloud computing-a relatively recent term-builds on decades of research in virtualization, distributed computing, utility computing, and, more recently, networking, and Web and software services. It implies a service-oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, on-demand services, and many other things. It is apparent that educational institutions are likely to seize those services offered in the cloud in these difficult times due to its pay-as-you-go cost structure. However, does the cloud have the answers to all the challenges in technical education? © 1988-2012 IEEE.
