Opposition is rarely a good preparation for government. The only postwar government to enter office confident, wellacquainted with the Civil Service and with a fund of administrative experience to draw on was the Attlee administration formed in 1945. The longer a party spends in opposition the more these assets disappear. Labour, by the end of the long period of Conservative rule in 195164, was largely unfamiliar with the burdens of office. This formed the background to the formulation of the DouglasHome rules, whereby informal contact is permitted between the Civil Service and the Opposition in advance of a general election. Since 1964 this arrangement has gradually become more extensive (especially after Neil Kinnock complained that the period for contact was too brief during the runup to the 1992 election) and more formalised. In late 1993 John Major agreed that contacts could be made from early 1996 in advance of the next election, rather than only during the last six months of a parliament, as had by then become the convention. The object of this short paper is, however, to explain how these rules originated.

The purpose of this paper is to analyse the issues related to home bias and foreign direct investments (FDIs). We study the role of physical, cultural, and institutional distances from home on FDI decisions taken by corporations to assess whether the globalization of the past two decades has reduced their influence. Using the home bias framework from the finance literature and the gravity model from the economics literature, we utilize a large sample of both developed and emerging markets, using FDI flows of 6263 unique bilateral country pairs over a 30-year period. We find strong empirical evidence of persistent home bias in FDI outflows, and we show that not only physical distance but also cultural and institutional similarities between host and source countries remain a decisive factor in foreign corporate investment decisions. We also show that such home bias is persistent over time and is observed around the world.

In future power systems, in the smart grid and microgrids operation paradigms, consumers can be seen as an energy resource with decentralized and autonomous decisions in the energy management. It is expected that each consumer will manage not only the loads, but also small generation units, heating systems, storage systems, and electric vehicles. Each consumer can participate in different demand response events promoted by system operators or aggregation entities. This paper proposes an innovative method to manage the appliances on a house during a demand response event. The main contribution of this work is to include time constraints in resources management, and the context evaluation in order to ensure the required comfort levels. The dynamic resources management methodology allows a better resources management in a demand response event, mainly the ones of long duration, by changing the priorities of loads during the event. A case study with two scenarios is presented considering a demand response with 30 min duration, and another with 240 min (4 h). In both simulations, the demand response event proposes the power consumption reduction during the event. A total of 18 loads are used, including real and virtual ones, controlled by the presented house management system.

Due to their detrimental effects on human health, scientific interest in ultrafine particles (UFP), has been increasing but available information is far from comprehensive. Children, who represent one of the most susceptible subpopulation, spend the majority of time in schools and homes. Thus, the aim of this study is to (1) assess indoor levels of particle number concentrations (PNC) in ultrafine and fine (201000 nm) range at school and home environments and (2) compare indoor respective dose rates for 3- to 5-yr-old children. Indoor particle number concentrations in range of 201000 nm were consecutively measured during 56 d at two preschools (S1 and S2) and three homes (H1H3) situated in Porto, Portugal. At both preschools different indoor microenvironments, such as classrooms and canteens, were evaluated. The results showed that total mean indoor PNC as determined for all indoor microenvironments were significantly higher at S1 than S2. At homes, indoor levels of PNC with means ranging between 1.09 104 and 1.24 104 particles/cm3 were 1070% lower than total indoor means of preschools (1.32 104 to 1.84 104 particles/cm3). Nevertheless, estimated dose rates of particles were 1.3- to 2.1-fold higher at homes than preschools, mainly due to longer period of time spent at home. Daily activity patterns of 3- to 5-yr-old children significantly influenced overall dose rates of particles. Therefore, future studies focusing on health effects of airborne pollutants always need to account for childrens exposures in different microenvironments such as homes, schools, and transportation modes in order to obtain an accurate representation of children overall exposure.

In this paper we present ezGo, an electric powered wheelchair with a speech based interface and biosignal monitoring instrumentation. The user can use the voice, a natural communication method, for controlling the chair movement and obtain information about his health. Additionally a set of semi-autonomous modes with macro recording enable the execution of navigation tasks with little effort and improved precision. The main purpose of the system is to provide severely disabled persons with an assistive device that can improve their confidence and daily independence. The obtained results on usability tests showed that users consider ezGo a valuable help on their daily tasks and a very desirable addition to standard wheelchairs.

Introduo: Cada vez mais a Reabilitao Cardaca (RC) tem um incio precoce no tratamento e nas necessidades do paciente no sentido de promover a sua autonomia e responsabilizao pela recuperao, atravs de uma abordagem multidisciplinar. Os programas home-based e a incluso das tecnologias de informao e comunicao so solues atrativas para o aumento da participao dos doentes selecionados e incluso de grupos de doentes atualmente sub-representados. Objetivos: Sistematizar a evidncia cientfica atual sobre a efetividade dos programas de reabilitao cardaca home-based com controlo distncia atravs da aplicao de novas tecnologias, comparando-a com a reabilitao centre-based/hospital-based, ao nvel da adeso e da atividade fsica. Mtodos: Este trabalho consiste numa reviso sistemtica da literatura publicada entre 2007 e 2014, atravs de uma pesquisa em diferentes bases de dados eletrnicas cientficas (Elsevier Science Direct, PEDro, PubMed, Scielo Portugal e B-on) com as palavras-chave: reabilitao cardaca, home-based, centre-based, hospital-based, reabilitao exercise-based, telemonitorizao, smartphone, internet, atividade fsica, em todas as combinaes possveis. Os estudos foram analisados independentemente por dois revisores quanto aos critrios de incluso e qualidade dos estudos. Resultados: Dos 101 estudos identificados, apenas dez foram includos. Considerando a escala da PEDro, quatro estudos obtiveram um score 5, quatro, um score de 6, e 2 com um score de 7 em 10.

Nursing home-acquired pneumonia (NHAP) is one of the most common infections arising amongst nursing home residents, and its incidence is expected to increase as population ages. The NHAP recommendation for empiric broad-spectrum antibiotic therapy, arising from the concept of healthcare-associated pneumonia, has been challenged by recent studies reporting low rates of multidrug-resistant (MDR) bacteria. This single center study analyzes the results of NHAP patients admitted through the Emergency Department (ED) at a tertiary center during the year 2010. There were 116 cases, male gender corresponded to 34.5% of patients and median age was 84years old (IQR 77-90). Comorbidities were present in 69.8% of cases and 48.3% of patients had used healthcare services during the previous 90days. In-hospital mortality rate was 46.6% and median length-of-stay was 9days. Severity assessment at the Emergency Department provided CURB65 index score and respective mortality (%) results: zero: n=0; one: n=7 (0%); two: n=18 (38.9%); three: n=26 (38.5%); four: n=30 (53.3%); and five; n=22 (68.2%); and sepsis n=50 (34.0%), severe sepsis n=43 (48.8%) and septic shock n=22 (72.7%). Significant risk factors for in-hospital mortality in multivariate analysis were polypnea (p=0.001), age75years (p=0.02), and severe sepsis or shock (p=0.03) at the ED. Microbiological testing in 78.4% of cases was positive in 15.4% (n=15): methicillin-resistant Staphylococcus aureus (26.7%), Pseudomonas aeruginosa (20.0%), S. pneumoniae (13.3%), Escherichia coli (13.3%), others (26.7%); the rate of MDR bacteria was 53.3%. This study reveals high rates of mortality and MDR bacteria among NHAP hospital admissions supporting the use of empirical broad-spectrum antibiotic therapy in these patients.
