Surfing or still drowning? Student nurses’ Internet skills

A study into student nurses’ ability to use the Internet was published in Nurse Education Today in 2004. This paper repeats the research with a cohort of students starting their pre-registration programme in a UK university in 2007. In 2004 students were reported as having poor Internet skills, and as not being frequent users of the Internet. In this study students were found to have significantly better ability to carry out basic tasks and significantly higher levels of Internet use. Their ability to apply these skills to more complex information literacy tasks however had not increased, with more than half of all students saying they found far too much irrelevant information when searching for specific information on the Internet. The earlier study found that skills and age were not related, which appears to still be the case. The need for these skills is increasing as education, lifelong learning, and patient information are all increasingly drawing on the developing Internet. Nurse education however is not integrating the skill and knowledge base essential to support this into pre-registration programmes, and the evidence suggests that this will not happen without active management

Hormonal regulation of ecdysis innate behavior in the hemimetabolous insect Rhodnius prolixus

In insects, ecdysis sequence is a series of stereotyped innate behaviors performed at the end of each molting period, in order to shed the old cuticle and to emerge as the following stage in the vital cycle. The hormonal regulation of ecdysis has been studied in holometabolous insects; it includes the participation of ecdysteroids and peptidic hormones. However, in spite of the fundamental differences in ecdysis between holometabolous and hemimetabolous, the hormonal regulation of this process has not been characterized in the latter.Facultad de Ciencias Exacta

Older and wiser? Men’s and women’s accounts of drinking in early mid-life

Most qualitative research on alcohol focuses on younger rather than older adults. To explore older people’s relationship with alcohol, we conducted eight focus groups with 36 men and women aged 35 to 50 years in Scotland, UK. Initially, respondents suggested that older drinkers consume less alcohol, no longer drink to become drunk and are sociable drinkers more interested in the taste than the effects of alcohol. However, as discussions progressed, respondents collectively recounted recent drunken escapades, challenged accounts of moderate drinking, and suggested there was still peer pressure to drink. Some described how their drinking had increased in mid-life but worked hard discursively to emphasise that it was age and stage appropriate (i.e. they still met their responsibilities as workers and parents). Women presented themselves as staying in control of their drinking while men described going out with the intention of getting drunk (although still claiming to meet their responsibilities). While women experienced peer pressure to drink, they seemed to have more options for socialising without alcohol than did men. Choosing not to drink alcohol is a behaviour that still requires explanation in early mid-life. Harm reduction strategies should pay more attention to drinking in this age group

Using workplace population statistics to understand retail store performance

We explore the value of recently released workplace geographies and accompanying census-based workplace zone statistics (WZS) and an associated classification of workplace zones (COWZ). We consider how these data could support retailers in their operational and strategic decision making, including the evaluation of retail demand and retail store performance in localities where trade is driven by non-residential demand. In collaboration with major UK grocery retailer ‘The Co-operative Group’ we explore the relationship between workplace population composition and store trading characteristics using a series of case study stores within Inner London. We use empirical store trading data to identify store and product category level temporal sales fluctuations attributable to workplace populations. We also use census-derived flow data to identify the spatial origins of workplace population inflow. We identify that store performance exhibits characteristics attributable to demand driven by these populations. We conclude that workplace population geographies, WZS and the COWZ afford considerable potential for understanding drivers of store performance, observed store trading patterns and evaluation of retail store performance. We suggest that the next step is to build these populations and their micro geography spatial and temporal characteristics into predictive models and evaluate their potential for store performance evaluation and location-based store and network decision making within this sector

The geography of wage inequality in British cities

There is widespread concern about the scale and implications of urban inequality in Great Britain, but little evidence on which cities are the most unequal and why. This paper investigates patterns of wage inequality in 60 British cities. It has two principal goals: (1) to describe which cities are most unequal and (2) to assess the important determinants of inequality. The results show a distinct geography of wage inequality, the most unequal cities tend to be affluent and located in parts of the Greater South East of England. A central determinant of these patterns is the geography of highly skilled workers. Because of this, the geography of urban wage inequality reflects the geography of affluence more generally

Who still dies young in a rich city? Revisiting the case of Oxford

There are substantial inequalities in mortality and life expectancy in England, strongly linked to levels of deprivation. Mortality rates among those who are homeless are particularly high. Using the city of Oxford (UK) as a case study, we investigate ward-level premature standardised mortality ratios for several three-year and five-year periods between 2002 and 2016, and explore the extent to which the mortality of people who become homeless contributed to any rise or fall in geographical inequalities during this period. Age–sex standardised mortality ratios (SMRs) for people aged under 65 years old, with and without deaths among the homeless population, were calculated using Office for National Statistics Death Registration data for England and Wales 2002−2016. Individuals who were homeless or vulnerably housed were identified using records supplied by a local Oxford homeless charity. We found that in an increasingly wealthy, and healthy, city there were persistent ward-level inequalities in mortality, which the city-wide decrease in premature mortality over the period masked. Premature deaths among homeless people in Oxford became an increasingly important contributor to the overall geographical inequalities in health in this city. In the ward with the highest SMR, deaths among the homeless population accounted for 73% of all premature deaths of residents over the whole period; in 2014–2016 this proportion rose to 88%. Homelessness among men (the vast majority of the known homeless population) in this gentrifying English city rose to become the key explanation of geographical mortality patterns in deaths before age 65 across the entire city, particularly after 2011. Oxford reflects a broader pattern now found in many places across England of increasing homeless deaths, widening geographical inequalities in life expectancy, and sharp increases in all-age SMRs. The answer to the question, “Who dies young in a rich, and in fact an even richer, place?” is – increasingly – the homeless

Novel Techniques for the Integration of Antennas and Photovoltaic Cells

Various novel approaches to the integration of antenna and photovoltaic technologies are proposed. These include the use of polycrystalline solar cells as groundplane for microstrip patch antennas as well as for reflectors of half-wave dipole antennas. Transparent materials were also evaluated as antenna radiating elements, allowing greater solar efficiency. A novel technique illustrating how emitter-wrap-through rear contact solar cells can be used as a folded-dipole antenna, which is located in the focal line of a parabolic solar concentrator, to provide high solar efficiency as well as high antenna gain, is presented
