Sequential injection of domain walls into ferroelectrics at different bias voltages: Paving the way for “domain wall memristors”

Simple meso-scale capacitor structures have been made by incorporating thin (300 nm) single crystal lamellae of KTiOPO4 (KTP) between two coplanar Pt electrodes. The influence that either patterned protrusions in the electrodes or focused ion beam milled holes in the KTP have on the nucleation of reverse domains during switching was mapped using piezoresponse force microscopy imaging. The objective was to assess whether or not variations in the magnitude of field enhancement at localised “hot-spots,” caused by such patterning, could be used to both control the exact locations and bias voltages at which nucleation events occurred. It was found that both the patterning of electrodes and the milling of various hole geometries into the KTP could allow controlled sequential injection of domain wall pairs at different bias voltages; this capability could have implications for the design and operation of domain wall electronic devices, such as memristors, in the future.

Government decisions before and during the First World War and the living standards in Germany during a drastic natural experiment

The First World War hit Germany severely, particularly the agricultural sector, because the outbreak came unexpected and its duration exceeded all expectations. Many resources necessary for agricultural production were required by the war economy and led to shortages and shrinking supplies. Many agricultural laborers were drafted and the blockade imposed by the allies prevented Germany from a great deal of imports. As a consequence, the nutritional situation was devastating, particularly after 1916, and hit all groups of the German society. The period under observation provides one of most drastic natural experiments in the 20th century. This study uses anthropometric data from German soldiers who served in the Second World War to trace living standards between the 1900s and the 1920s. In contrast to other approaches, this paper is able to distinguish between social groups by occupation, religious denominatio\n, regional origin, and city size. The results suggest that although all social strata were hit by famine conditions, the height of farmers, urban citizens, Catholics, and especially individuals born in the highly integrated food-import regions along the coast and the banks of the Rhine declined most.

The influence of inequality on the standard of living: Worldwide anthropometric evidence from the 19th and 20th centuries

We provide empirical evidence on the existence of the Pigou–Dalton principle. The latter indicates that aggregate welfare is – ceteris paribus – maximized when incomes of all individuals are equalized (and therefore marginal utility from income is as well). Using anthropometric panel data on 101 countries during the 19th and 20th centuries, we determine that there is a systematic negative and concave relationship between height inequality and average height. The robustness of this relationship is tested by means of several robustness checks, including two instrument variable regressions. These findings help to elucidate the impact of economic inequality on welfare.

Cultural and Genetic Influences on the “Biological Standard of Living”

This study suggests an improvement of a popular measure of living standards, namely the biological standard of living. One influence on it is a population's consumption pattern. Since there are different dietary patterns all over the world, researchers estimate the influences of national diets on final average male height. These habits are predominantly related to income, but also to genetics, cultural history, and decisions regarding whether to trade or consume high-quality foodstuffs. Systematic differences are found when analyzing protein-consumption habits among 51 countries between the 1960s and the 1980s. The author calculates metric correction values which can facilitate international comparisons of male average height. While the proposed correction values make a little difference on average, they can be valuable in a comparison of countries with markedly different dietary patterns.

Living in The Matrix: Virtual Reality Systems and Hyperspatial Representation in Architecture

In the digital age, the hyperspace of virtual reality systems stands out as a new spatial concept creating a parallel realm to "real" space. Virtual reality influences one’s experience of and interaction with architectural space. This "otherworld" brings up the criticism of the existing conception of space, time and body. Hyperspaces are relatively new to designers but not to filmmakers. Their cinematic representations help the comprehension of the outcomes of these new spaces. Visualisation of futuristic ideas on the big screen turns film into a medium for spatial experimentation. Creating a possible future, The Matrix (Andy and Larry Wachowski, 1999) takes the concept of hyperspace to a level not-yet-realised but imagined. With a critical gaze at the existing norms of architecture, the film creates new horizons in terms of space. In this context, this study introduces science fiction cinema as a discussion medium to understand the potentials of virtual reality systems for the architecture of the twenty first century. As a "role model" cinema helps to better understand technological and spatial shifts. It acts as a vehicle for going beyond the spatial theories and designs of the twentieth century, and defining the conception of space in contemporary architecture.

Echoes of the future: Adults with disabilities living at home with their parents

Almost 90% of all adult sons and daughters with disabilities live at home with their parents. Consequently, they have life experiences that are atypical for most of their adult peers and their aging caregivers are under stress due to failing health, financial pressures, bereavement, and worry about the future.

Adults with intellectual disabilities and aging parents took part in focus groups and interviews. results show a loving and caring home environment but evidence a lack of effective life skills development and futures planning. the paper draws attention to the inevitable crisis that occurs when aging caregivers are no longer able to care. The urgent need for skill development and timely futures planning is outlined.

At Home in Care: Children living with birth parents on a Care Order

This study explored the processes, background information, and perceived reasons why children and young people returned home while remaining in care, in the five HSC Trusts in Northern Ireland. The research also focused on understanding the functions the Care Order had for social services, the birth parents, and young people involved.
It was found that on 31st March 2009, there were 193 children/young people living with their birth parents on a Care Order in Northern Ireland. This is eight per cent of the total population of Looked After children, and is lower than had been anticipated from governmental statistics. In total, the case files of 47 of these young people (24% of them) were reviewed, and interviews were conducted with ten of them and their birth parent/s.
The analysis revealed that the majority of them had in common a parental background history of alcohol abuse and domestic violence, and most return breakdowns in the study were related to continuing parental alcohol and/or drugs misuse. While some children had a planned return home after parents had engaged in supports and completed assessments, many young people had returns that were not planned, as they initiated the move themselves, or previous foster placements had broken down and there were no alternative placements identified for them. Many of these young people essentially ‘voted with their feet’, and social services were required to ensure that they remained safe in often less than optimal circumstances.
After returning home, for many, Care Orders remained for initially unintended lengthy periods because of the risks posed by parents’ intermittent alcohol abuse and their lifestyle, contact issues, and parents’ desire to ensure that their children were able to access the supports that they needed. Thus, Care Orders at home tended to serve two main functions: to either monitor and/or support the placement.

Parker Morris and the economies of the Fordist house

The Parker Morris report of 1961 attempted, through the application of scientific principles, to define the minimum living space standards needed to accommodate household activities. But while early modernist research into ideas of existenzminimum were the work of avant-garde architects and thinkers, this report was commissioned by the British State. This normalization of scientific enquiry into space can be considered not only a response to new conditions in the mass production of housing – economies of scale, prefabrication, system-building and modular coordination – but also to the post-war boom in consumer goods. The domestic interior was assigned a key role as a privileged site of mass consumption as the production and micro-management of space in Britain became integral to the development of a planned national economy underpinned by Fordist principles. The apparently placeless and scale-less diagrams executed by Gordon Cullen to illustrate Parker Morris emblematize these relationships. Walls dissolve as space flows from inside to outside in a homogenized and ephemeral landscape whose limits are perhaps only the boundaries of the nation state and the circuits of capital.

Living with and beyond cancer: the role of Holistic Needs Assessment and care planning.

Due to earlier diagnosis and more effective treatment, increasing numbers of people can be expected to live with and beyond cancer. Yet for many, survival might be characterised by physical and psychological morbidity, decreased functional status and disability, which may increase as the length of time from the completion of treatment extends. However, careful integrated assessment and relevant and acceptable care planning can mitigate these effects; people can be helped and supported in self-management and ultimately enabled to live full and productive lives in a manner that is acceptable to them.

Supporting delivery of the recovery package for people living with and beyond cancer

Survivorship is an important issue in cancer care in the UK. More people are being diagnosed with the disease and many more are living for longer after diagnosis. The National Cancer Survivorship Initiative recommends that patients with cancer have a package of care designed to improve outcomes and support for those living with and beyond the disease. The recovery package consists of a holistic needs assessment, treatment summary, cancer care review and health and wellbeing event. Although these interventions are recommended as a way to improve care, many people do not have access to the combined package, or even some of its components. The Cancer Nursing Partnership (CNP), a collaboration of cancer nursing organisations and communities of influence, has been established to support nurses with delivery of the recovery package in practice. This article describes the package and its components, introduces the CNP and outlines the work it has carried out to date.

Desire for fertility and associated factors among people living with HIV/AIDS (PLWHA) in selected antiretroviral therapy (ART) clinics of Horro Guduru Wollega Zone, North West Oromia, Ethiopia- A cross sectional study

Background: Most recently fertility issues in HIV positive men and women are becoming increasingly important. Because of ART access and its good life effect, it is expected that the need and desire to get married, to have children and to have sexual partners for PLWHA would change with the regard to reproductive health. In Ethiopia HIV positive individuals may or may not have desire to have children. And the extent of this desire and how it varies by individual, health and demographic characteristics is not well known.

Objective: the aim of the study was to assess desire for fertility and associated factors among PLWHA in selected ART clinics of Horro Guduru Wollega Zone, Oromia National Regional State, Ethiopia.

Methods: A cross-sectional, institutional-based study that employed quantitative and qualitative in-depth interviews was conducted. Three hundred twenty one study subjects were selected using systematic random sampling technique and the data was collected using interviewer administered structured questionnaire. Data entry and analysis were performed using EPI Info version 3.5.1 and SPSS version 16. P-value <0.05 was taken as statistically significant and logistic regression was used to control potential confounding factors.

Results: Seventy three (57.9%) of the males and seventy six (39%) of the females desired to have children, giving a total of 149(46.4%) of all study participants. PLWHA who desired children were younger (AOR:3.3, 95%CI: 1.3-8.9), married (AOR: 5.8, 95%CI: 2.7-12.8), had no children (AOR: 75, 95%CI: 20.1-273.3) and males (AOR; 1.9, 95%CI: 1.02-3.62) compared with their counter parts. The major reason for those people who did not desire children were having desired number of children 80 (46.5%) followed by fear of HIV transmission to child reported by 42 (24.4%) of them.

Conclusion: A considerable number of PLWHA wants to have a child currently or in the near future. Many variables like socio demography, partner related, number of alive children and HIV related disease condition were significantly associated with fertility desire.

The validation of Fibit ZipTM physical activity monitor as a measure of free-living physical activity

BACKGROUND: The new generation of activity monitors allow users to upload their data to the internet and review progress. The aim of this study is to validate the Fitbit Zip as a measure of free-living physical activity.

FINDINGS: Participants wore a Fitbit Zip, ActiGraph GT3X accelerometer and a Yamax CW700 pedometer for seven days. Participants were asked their opinion on the utility of the Fitbit Zip. Validity was assessed by comparing the output using Spearman's rank correlation coefficients, Wilcoxon signed rank tests and Bland-Altman plots. 59.5% (25/47) of the cohort were female. There was a high correlation in steps/day between the Fitbit Zip and the two reference devices (r = 0.91, p < 0.001). No statistically significant difference between the Fitbit and Yamax steps/day was observed (Median (IQR) 7477 (3597) vs 6774 (3851); p = 0.11). The Fitbit measured significantly more steps/day than the Actigraph (7477 (3597) vs 6774 (3851); p < 0.001). Bland-Altman plots revealed no systematic differences between the devices.

CONCLUSIONS: Given the high level of correlation and no apparent systematic biases in the Bland Altman plots, the use of Fitbit Zip as a measure of physical activity. However the Fitbit Zip recorded a significantly higher number of steps per day than the Actigraph.

Report on the 2014 UKONS Annual Conference Belfast, 14–15 November 2014: focus on living with and beyond cancer, patient information and support, and innovations in treatment and care

The UK Oncology Nursing Society’s (UKONS) annual conference focused on three major themes. These were ‘Living With and Beyond Cancer’, ‘Patient Information and Support’, and ‘Innovations in Treatment and Care’. It featured a wide range of presentations, industry satellites, exhibitions, poster discussions. and workshops. Presenters ranged from those eminent in their particular field to those gracing the speaker’s podium for the first time. The rich variety of presentations covered policy, cancer trends, clinical developments, care initiatives, personal development, and advances in practice. There was a strong emphasis on skills, knowledge, values, and attitudes, with the most junior and novice nurses mixing with experienced and highly esteemed practitioners.
