Inclusion criteria, Types of participants, Adult caregivers who provide support for people with dementia living in the community (non-institutional care). Types of interventions, Interventions designed to support caregivers in their role such as skills training, education to assist in caring for a person living with dementia and support groups/programs. Interventions of formal approaches to care designed to support caregivers in their role, care planning, case management and specially designated members of the healthcare team , for example dementia nurse specialist or volunteers trained in caring for someone with dementia. Types of studies, This review considered any meta-analyses, systematic reviews, randomised control trials, quasi-experimental studies, cohort studies, case control studies and observational studies without control groups that addressed the effectiveness of interventions that assist caregivers to provide support for people living with dementia in the community. Search strategy, The search sought to identify published studies from 2000 to 2005 through the use of electronic databases. Only studies in English were considered for inclusion. The initial search was conducted of the databases, CINAHL, MEDLINE and PsychINFO using search strategies adapted from the Cochrane Dementia and Cognitive Improvement Group. A second more extensive search was then conducted using the appropriate Medical Subject Headings (MeSH) and keywords for other available databases. Finally, hand searching of reference lists of articles retrieved and of core dementia, geriatric and psycho geriatric journals was undertaken. Assessment of quality, Methodological quality of each of the articles was assessed by two independent reviewers using appraisal checklist developed by the Joanna Briggs Institute and based on the work of the Cochrane Collaboration and Centre for Reviews and Dissemination. Data collection and analysis, Standardised mean differences or weighted mean differences and their 95% confidence intervals were calculated for each included study reported in the meta-analysis. Results from comparable groups of studies were pooled in statistical meta-analysis using Review Manager Software from the Cochrane Collaboration. Heterogeneity between combined studies was tested using standard chi-square test. Where statistical pooling was not appropriate or possible, the findings are summarised in narrative form. Results, A comprehensive search of relevant databases, hand searching and cross referencing found 685 articles that were assessed for relevance to the review. Eighty-five papers appeared to meet the inclusion criteria based on title and abstract, and the full paper was retrieved. Of the 85 full papers reviewed, 40 were accepted for inclusion, three were systematic reviews, three were meta-analysis, and the remaining 34 were randomised controlled trials. For the randomised controlled trials that were able to be included in a meta-analysis, standardised mean differences or weighted mean differences and their 95% confidence intervals were calculated for each. Results from comparable groups of studies were pooled in statistical meta-analysis using Review Manager Software and heterogeneity between combined studies was assessed by using the chi-square test. Where statistical pooling was not appropriate or possible, the findings are summarised in narrative form. The results are discussed in two main sections. Firstly it was possible to assess the effectiveness of different types of caregiver interventions on the outcome categories of depression, health, subjective well-being, self-efficacy and burden. Secondly, results are reported by main outcome category. For each of these sections, meta-analysis was conducted where it was possible; otherwise, a narrative summary describes the findings. Effectiveness of intervention type, Four categories of intervention were included in the review , psycho-educational, support, multi-component and other. Psycho-educational Thirteen studies used psycho-educational interventions, and all but one showed positive results across a range of outcomes. Eight studies were entered in a meta-analysis. No significant impact of psycho-educational interventions was found for the outcome categories of subjective well-being, self-efficacy or health. However, small but significant results were found for the categories of depression and burden. Support Seven studies discussed support only interventions and two of these showed significant results. These two studies were suitable for meta-analysis and demonstrated a small but significant improvement on caregiver burden. Multi-component Twelve of the studies report multi-component interventions and 10 of these report significant outcomes across a broad range of outcome measures including self-efficacy, depression, subjective well-being and burden. Unfortunately because of the heterogeneity of study designs and outcome measures, no meta-analysis was possible. Other interventions Other interventions included the use of exercise or nutrition which resulted in improvements in psychological distress and health benefits. Case management and a computer aided support intervention provided mixed results. One cognitive behavioural therapy study reported a reduction in anxiety and positive impacts on patient behaviour. Effectiveness of interventions using specific outcome categories, In addition to analysis by type of intervention it was possible to analyse results based on some outcome categories that were used across the studies. In particular the impact of interventions on caregiver depression was available for meta-analysis from eight studies. This indicated that multi-component and psycho-educational interventions showed a small but significant positive effect on caregiver depression. Five studies using the outcome category of caregiver burden were entered into a meta-analysis and findings indicated that there were no significant effects of any of interventions. No meta-analysis was possible for the outcome categories of health, self-efficacy or subjective well-being. Implications for practice, From this review there is evidence to support the use of well-designed psycho-educational or multi-component interventions for caregivers of people with dementia who live in the community. Factors that appear to positively contribute to effective interventions are those which: ,,Provide opportunities within the intervention for the person with dementia as well as the caregiver to be involved ,,Encourage active participation in educational interventions for caregivers ,,Offer individualised programs rather than group sessions ,,Provide information on an ongoing basis, with specific information about services and coaching regarding their new role ,,Target the care recipient particularly by reduction in behaviours Factors which do not appear to have benefit in interventions are those which: ,,Simply refer caregivers to support groups ,,Only provide self help materials ,,Only offer peer support [source] The Abdullah Peace Plan: Offer or Ultimatum?MIDDLE EAST POLICY, Issue 3 2002Mamoun Fandy The following is an edited transcript of the twenty,ninth in a series of Capitol Hill conferences convened by the Middle East Policy Council.

Oswald Is affluence a good thing? The book The Challenge of Affluence by Avner Offer (2006) argues that economic prosperity weakens self-control and undermines human well-being. Consistent with a pessimistic view, we show that psychological distress has been rising through time in modern Great Britain. Taking over-eating as an example, our data reveal that half the British population view themselves as overweight, and that happiness and mental health are worse among fatter people in Britain and Germany. Comparisons also matter. We discuss problems of inference and argue that longitudinal data are needed. We suggest a theory of obesity imitation where utility depends on relative weight. [source] The "ANRC has Withdrawn its Offer": Paul Kirchhoff, Academic Freedom and the Australian Academic Establishment,AUSTRALIAN JOURNAL OF POLITICS AND HISTORY, Issue 3 2006Geoffrey Gray The main focus of examinations of intellectual suppression and censorship of scholars and academics in Australia has been on the post-1945 period, particularly the Cold War. The interwar years have, in comparison, received little attention, resulting in a lack of historical understanding of the development of censorious structures and traditions in Australia. In this paper I discuss the exclusion of Paul Kirchhoff, a German anthropologist, a member of the German Communist Party and a Jew, from undertaking anthropological research in Australia, including its external territories, between 1931 and 1932. Kirchhoff applied for a research grant from the Australian National Research Council (ANRC) which, although awarded, was withdrawn once the Executive Committee was informed by the Australian government that the British MI5 considered him a security risk. His membership of the Communist Party was the reason put forward. This case also underlines the transnational aspect of security services and the international reach of academic anthropology. Kirchhoff was a victim of the ANRC's sympathetic collaboration with the Commonwealth Attorney-General's office to stifle academic and civil freedom. [source] Gender differences in the ultimatum gameECONOMIC INQUIRY, Issue 2 2001SJ Solnick I explore the behavior of men and women in the ultimatum game. In one treatment, players remain mutually anonymous. In the second treatment, players'gender is common knowledge. Average offers made do not differ based on the gender of player 1. Offers are affected by the gender of player 2, with men attracting higher offers, particularly from female players 1. Players 2 of both genders choose a higher minimum acceptable offer when facing a female player 1. These patterns led to substantial differences in earnings. Such striking differences in expectations and decisions could impact salary negotiations and other real-world transactions. [source] Fair Offers in a Repeated Principal,Agent Relationship with Hidden ActionsECONOMICA, Issue 286 2005François Cochard We test a repeated principal,agent relationship with hidden actions in the laboratory. At each period, the principal offers payments to the agent in order to induce him to provide the high effort level. The agent can accept or reject the offer; if he accepts it, he can choose the high or the low effort level. We observe that offered payments are higher than predicted by the subgame-perfect equilibrium, and higher in the partners' than in the strangers' design. Furthermore, agents strategically reject inequitable offers in early rounds in order to induce principals to increase payments in the subsequent rounds. [source] Fluctuating Asymmetry of Responders Affects Offers in the Ultimatum Game Oppositely According to Attractiveness or Need as Perceived by ProposersETHOLOGY, Issue 7 2009Darine Zaatari The Ultimatum Game (UG) measures cooperative tendencies in humans. A proposer offers to split a given sum of money between self and a responder, who may accept or reject the offer. If accepted, each receives the proposed split; if rejected, nobody receives anything. We studied the effect of the putative responder's degree of facial symmetry (fluctuating asymmetry, FA) on the offer he/she received in opposite-sexed UGs. Symmetry is an important measure of biological quality so subjects were expected to receive higher offers when symmetrical than asymmetrical. In a sample of Jamaicans, individuals played two UGs with opposite-sexed responders, a symmetrical photo of a Lebanese and an asymmetrical one. Individuals do indeed give more to symmetrical responders (p = 0.032). When subjects are asked their motivation, a striking dichotomy emerges: those who cite ,attractiveness' as a motive, give strongly to symmetrical responders while those citing ,need' invariably give more to asymmetrical ones (p < 0.0001). Females also show a nearly significant tendency to cite need as a motive more often than do males. [source] Share Repurchase Offers and Liquidity: An Examination of Temporary and Permanent EffectsFINANCIAL MANAGEMENT, Issue 2 2008Nandkumar Nayar Open-market repurchase programs do not allow for precise estimates of share buy-back intensity to measure liquidity effects. To circumvent the uncertainty surrounding the quantity and timing of shares truly acquired in repurchase programs and to measure their long-term impact, we examine Dutch auctions and fixed-price tender offers. We investigate both the temporary and permanent liquidity effects of share repurchase programs and find that the improvement in liquidity is transitory and limited to the tender period when the firm's offer to repurchase shares is outstanding. Improvements in liquidity over longer intervals appear to be the result of an overall price improvement and a reduction in volatility rather than the result of structural change in market dynamics.

The findings are resilient to a number of methodological controls. In contrast, our results for a smaller sample of open offers made during 1991-95 show strong positive performance over a 5-year post-issue period, implying that firms making open offers had better growth prospects than firms making rights issues. During 1986-90, a period when open offers were rarely used, firms appeared to be making rights issues to exploit overvaluation. However, this was not evident for rights issues made during 1991-95, a period when open offers were more commonly used. [source] An Analysis of Nonunderwritten Rights Offers: The Case of Closed-END FundsTHE JOURNAL OF FINANCIAL RESEARCH, Issue 2 2002James A. Miles Abstract We study nonunderwritten rights offerings without subscription pre-commitments from large shareholders. The results indicate firms incur substantial indirect costs in the form of price concessions for raising equity capital this way. The data therefore support the selling cost explanation of the rights-offering paradox. Additionally, we describe how market participants collectively respond to intermediate such offerings. [source] Consumer Perceptions of Promotional Offers in the Performing Arts: An Experimental ApproachCANADIAN JOURNAL OF ADMINISTRATIVE SCIENCES, Issue 3 2004Alain D'Astous This article reports the results of an experimental study in which four characteristics of sales promotions in the performing arts were manipulated: the type of promotion, the type of performance, the attractiveness of the performance, and the fit between the promotion and the performance. The results show that these factors had interactive effects on consumer reactions. Thus, although the fit between the promotion and the performance had a generally positive impact on consumer appreciation of the promotional offer, this effect was more important when the performance was more attractive. Sales promotions that closely fit the performing arts category were less likely to be perceived as manipulative when the performances were less attractive. We conclude that more research is needed on this managerially relevant topic in light of the complex dynamics that appear to underlie the relationships between the characteristics of sales promotions and consumer reactions. Résumé Cet article présente les résultats d'une étude expérimentale dans laquelle quatre facettes d'une promotion des ventes dans le contexte des arts de la scène ont été manipulées: le type de promotion, le type de performance, l'attrait de la performance et le lien entre la promotion et la performance. Les résultats montrent que ces facteurs ont des effets interactifs sur les réactions des consommateurs. Ainsi, même si le lien entre la promotion et la performance a un impact positif sur l'appréciation d'une offre promotionnelle, cet impact est plus important lorsque la performance est plus attrayante. Les promotions des ventes qui ont un lien fort avec le type d'art de la scène sont moins susceptibles d'être perçues comme des tentatives de manipulation. On conclut qu'il est nécessaire defaire plus de recherche sur ce sujet qui est pertinent pour les gestionnaires étant donné l'apparente complexité qui sous-tend les relations entre les caractéristiques des promotions des ventes et les réactions des consommateurs. [source] Confronting Uncertainty and Missing Values in Environmental Value Transfer as Applied to Species ConservationCONSERVATION BIOLOGY, Issue 5 2010SONIA AKTER conservación de especies; error de transferencia; incertidumbre; transferencia de valor ambiental; valores de no uso Abstract:,The nonuse (or passive) value of nature is important but time-consuming and costly to quantify with direct surveys. In the absence of estimates of these values, there will likely be less investment in conservation actions that generate substantial nonuse benefits, such as conservation of native species. To help overcome decisions about the allocation of conservation dollars that reflect the lack of estimates of nonuse values, these values can be estimated indirectly by environmental value transfer (EVT). EVT uses existing data or information from a study site such that the estimated monetary value of an environmental good is transferred to another location or policy site. A major challenge in the use of EVT is the uncertainty about the sign and size of the error (i.e., the percentage by which transferred value exceeds the actual value) that results from transferring direct estimates of nonuse values from a study to a policy site, the site where the value is transferred. An EVT is most useful if the decision-making framework does not require highly accurate information and when the conservation decision is constrained by time and financial resources. To account for uncertainty in the decision-making process, a decision heuristic that guides the decision process and illustrates the possible decision branches, can be followed. To account for the uncertainty associated with the transfer of values from one site to another, we developed a risk and simulation approach that uses Monte Carlo simulations to evaluate the net benefits of conservation investments and takes into account different possible distributions of transfer error. This method does not reduce transfer error, but it provides a way to account for the effect of transfer error in conservation decision making. Our risk and simulation approach and decision-based framework on when to use EVT offer better-informed decision making in conservation. Resumen:,El valor de no uso (o pasivo) de la naturaleza es importante pero su cuantificación con muestreos pasivos consume tiempo y es costosa. En ausencia de estimaciones de estos valores, es probable que haya menos inversión en acciones de conservación que generen beneficios de no uso sustanciales, tal como la conservación de especies nativas. Para ayudar a superar decisiones respecto a la asignación de dólares para conservación que reflejan la carencia de estimaciones de los valores de no uso, estos valores pueden ser estimados indirectamente por la transferencia de valor ambiental (TVA). La transferencia de valor ambiental utiliza datos existentes o información de un sitio de estudio de tal manera que el valor monetario estimado de un bien ambiental es transferido a otro sitio. Un reto mayor en el uso de TVA es la incertidumbre sobre la señal y el tamaño del error (i.e., el porcentaje en que el valor transferido excede al valor actual) que resulta de la transferencia de estimaciones directas de los valores de no uso de un sitio de estudio a uno político, el sitio adonde el valor es transferido. Una TVA es más útil si el marco de toma de decisiones no requiere información muy precisa y cuando la decisión de conservación está restringida por tiempo y recursos financieros. Para tomar en cuenta la incertidumbre en el proceso de toma de decisiones, se puede seguir una decisión heurística que guie el proceso de decisión e ilustre sobre las posibles ramificaciones de la decisión. Para tomar en cuenta la incertidumbre asociada con la transferencia de valores de un sitio a otro, desarrollamos un método de riesgo y simulación que utiliza simulaciones Monte Carlo para evaluar los beneficios netos de las inversiones de conservación y que considera posibles distribuciones diferentes de la transferencia de error. Este método no reduce el error de transferencia, pero proporciona una manera para considerar el efecto del error de transferencia en la toma de decisiones de conservación. Nuestro método de riesgo y simulación y el marco de referencia basado en decisones sobre cuando utilizar TVA permiten la toma de decisiones en conservación más informadas. [source] INJUSTICE AND IRRATIONALITY IN CONTEMPORARY YOUTH POLICYCRIMINOLOGY AND PUBLIC POLICY, Issue 4 2004DONNA M. BISHOP Lionel Tate was 12 years old when he killed 6-year-old Tiffany Eunick. Tiffany had been staying at the Tate home and, by all accounts, got along well with Lionel. The two were playing at "wrestling" when Lionel decided to try out some moves that he had seen on television. He threw Tiffany across the room, inflicting fatal injuries. Despite the boy's tender age, the prosecutor transferred Lionel to criminal court on a charge of first-degree murder, an offense carrying a mandatory penalty of life without parole. The boy was given an opportunity to plead guilty to second-degree murder in return for a sentence of three years incarceration, but he rejected the offer. A jury subsequently convicted him of first-degree murder. At sentencing, the prosecution recommended leniency, which drew an angry response from the judge: If the state believed the boy did not deserve to be sent to prison for life, why hadn't it charged him with a lesser offense? Without any inquiry into the boy's cognitive, emotional, or moral maturity, the judge imposed the mandatory sentence.1 Raymond Gardner was 16 years old when he shot and killed 20-year-old Mack Robinson.2 Raymond lived in a violent urban neighborhood with his mother, who kept close watch over him. He had no prior record. He was an A student and worked part-time in a clothing store to earn money for college. On the day of the shooting, a friend came into the store to tell Raymond that Mack had a beef with him about talking to a girl, and was "looking to get him." The victim was known on the street as "Mack the Knife" because he always carried a small machete and was believed to have stabbed several people. To protect himself on the way home, Raymond took the gun kept under the counter of the shop where he worked. As he neared home, Mack and two other men approached and blocked his path. According to eyewitness testimony, Raymond began shaking, then pulled out the gun and fired. Mack ran into the street and fell. Raymond followed and fired five more shots into the victim's back as he lay dying on the ground. Raymond did not run. He just stood there crying. The prosecutor filed a motion in juvenile court to transfer Raymond on a charge of first-degree murder. The judge ordered a psychological evaluation, which addressed the boy's family and social background, medical and behavioral history, intelligence, maturity, potential for future violence and prospects for treatment. The judge subsequently denied the transfer motion. He found Raymond delinquent and committed him to a private psychiatric treatment facility.3 [source] Design Brings Innovation to the Base of the PyramidDESIGN MANAGEMENT REVIEW, Issue 2 2009Aguinaldo Dos Santos In Brazil, nearly half the population earns less than $325 a month and lives in rural areas or urban shantytowns. Despite this reality, Brazilian companies tend to ignore the poor as consumers, focusing their efforts on the haves. One company, however, saw possibility in the "bottom of the pyramid (BOP)" and devised a way to serve this population and at the same time offer it a way to climb out of poverty. [source] ,Milking The Elephant': Financial Markets as Real Markets in KenyaDEVELOPMENT AND CHANGE, Issue 2 2004Susan Johnson Financial liberalization policies in the 1990s were intended to raise formal sector interest rates, enhance competition and expand access for users. This article investigates patterns of provision and use in a local financial market in Karatina, Kenya, at the end of the 1990s after a period of financial and economic liberalization. It takes a holistic approach, examining both formal and informal financial arrangements and microfinance interventions. This is because the role of the informal financial sector is particularly important for poor people and has received relatively little attention in the discussion of the consequences of reform. The author does this using a ,real' markets approach that sees markets as socially regulated and structured. Significant provision by the mutual sector (formal and informal), and poor lending performance by the banking sector is explained through an examination of the characteristics of the services on offer and their embeddedness in social relations, culture and politics. [source] Neuroanatomical substrates of social cognition dysfunction in autismDEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 4 2004Kevin Pelphrey Abstract In this review article, we summarize recent progress toward understanding the neural structures and circuitry underlying dysfunctional social cognition in autism. We review selected studies from the growing literature that has used the functional neuroimaging techniques of cognitive neuroscience to map out the neuroanatomical substrates of social cognition in autism. We also draw upon functional neuroimaging studies with neurologically normal individuals and individuals with brain lesions to highlight the insights these studies offer that may help elucidate the search for the neural basis of social cognition deficits in autism. We organize this review around key brain structures that have been implicated in the social cognition deficits in autism: (1) the amygdala, (2) the superior temporal sulcus region, and (3) the fusiform gyrus. We review some of what is known about the contribution of each structure to social cognition and then review autism studies that implicate that particular structure. We conclude with a discussion of several potential future directions in the cognitive neuroscience of social deficits in autism. © 2004 Wiley-Liss, Inc. MRDD Research Reviews 2004;10:259,271. [source] On What Powers Cannot DoDIALECTICA, Issue 3 2005Joel Katzav Dispositionalism is the view that the world is, ultimately, just a world of objects and their irreducible dispositions, and that such dispositions are, ultimately, the sole explanatory ground for the occurrence of events. This view is motivated, partly, by arguing that it affords, while non-necessitarian views of laws of nature do not afford, an adequate account of our intuitions about which regularities are non-accidental. I, however, argue that dispositionalism cannot adequately account for our intuitions about which regularities are non-accidental. Further, I argue that, intuitions aside, if we suppose that our world contains objects along with their irreducible dispositions, we must suppose, on pain of logical incoherence, that it contains laws of nature that are incompatible with a dispositionalist ontology. Indeed, if we suppose a world of objects and irreducible dispositions, we will have to suppose that the most prominent views of laws of nature currently on offer are all inadequate. [source] Food Security in Complex Emergencies: Enhancing Food System ResilienceDISASTERS, Issue 2005Prabhu Pingali This paper explores linkages between food security and crisis in different contexts, outlining the policy and institutional conditions needed to manage food security during a crisis and to rebuild the resilience of food systems in periods of relative peace. The paper reviews experiences over the past decade of countries in protracted crisis and draws lessons for national and international policy. It assesses the different alternatives on offer in fragile countries to address, for example, the disruption of institutional mechanisms and the decreasing level of support offered by international donors with respect to longer-term expectations. It proposes a Twin Track Approach to enhance food security resilience through specific policies for protracted crises that link immediate hunger relief interventions with a long-term strategy for sustainable growth. Finally, the article analyses policy options and the implications for both short- and longer-term responses vis-à-vis the three dimensions of food security: availability; access; and stability. [source] Influence of ambient light on the evolution of colour signals: comparative analysis of a Neotropical rainforest bird communityECOLOGY LETTERS, Issue 4 2004Doris Gomez Abstract Rainforests offer two contrasted light environments: a bright canopy rich in blue and UV and a dark understorey, rich in green and orange. Therefore, natural selection for crypsis should favour dark brown signals in understorey and bright green signals in canopy, whereas sexual selection for conspicuousness should favour bright yellow-red signals in understorey and dark blue and UV signals in canopy. Using spectrometry and comparative analyses, we examined the relationship between ambient light and colour signals in a bird community of French Guiana. It appears that brightness and hue are mostly naturally selected, while UV content of plumage is more likely sexually selected. At each height, both sexes present similar coloration but males display more conspicuous sexually selected patterns than females. These results show that ambient light drives the evolution of colour signals at community scale, and should be considered when studying signalling in other communities and light-contrasted ecosystems. [source] Bargaining without a Common Prior,An Immediate Agreement TheoremECONOMETRICA, Issue 3 2003Muhamet Yildiz In sequential bargaining models without outside options, each player's bargaining power is ultimately determined by which player will make an offer and when. This paper analyzes a sequential bargaining model in which players may hold different beliefs about which player will make an offer and when. Excessive optimism about making offers in the future can cause delays in agreement. The main result states that, despite this, if players will remain sufficiently optimistic for a sufficiently long future, then in equilibrium they will agree immediately. This result is also extended to other canonical models of optimism. [source] THE ROLE OF THE BIDDING PROCESS IN PRICE DETERMINATION: JUMP BIDDING IN SEQUENTIAL ENGLISH AUCTIONSECONOMIC INQUIRY, Issue 3 2008YARON RAVIV This paper uses data collected from a series of public auctions of used cars in New Jersey to examine how strategic bidding affects price determination in open-outcry English auctions. "Jumps" in the bidding, which occur when a new offer exceeds the old offer by more than the minimum bid increment, are highly pervasive and consistently related to the item's presale estimated price. The size of the jumps is not affected by the selling order, however. This jump bidding pattern suggests that open-outcry auctions are more appropriately interpreted with models that assume common-item valuations rather than models assuming private valuations.

[source] Increasing hospital-wide delivery of smoking cessation care for nicotine-dependent in-patients: a multi-strategic intervention trialADDICTION, Issue 5 2009Megan Freund ABSTRACT Aims, design and intervention Smoking care provision to in-patients is important in assisting smoking cessation and for management of nicotine withdrawal. Limited studies have reported the effectiveness of interventions designed to increase the hospital-wide provision of such care. A quasi-experimental matched-pair trial, involving two intervention and two control hospitals in NSW, Australia, investigated whether a multi-strategic intervention increased hospital-wide smoking care provision. Participants and measurements Patient surveys (n = 274,347 per experimental condition), medical notes audits (n = 181,228) and health professional surveys (n = 229,302) were used to collect outcome data at baseline and follow-up. Findings Significantly greater increases in intervention hospitals compared to control hospitals were found for patient-reported offer of nicotine replacement therapy (NRT) (intervention 34% versus control 12%), provision of NRT (16% versus 4%) and provision of written resources (11% versus 2%), and for the recording in medical notes of smoking management discussion (13% versus 3%), offer of NRT (24% versus 3%) and provision of NRT (21% versus 5%). Intervention group health professionals reported significantly greater increases in the mean estimate of patients who: had their smoking management discussed (30% versus 17%); were offered or provided with NRT (30% versus 18%); were asked their intention to smoke post-discharge (22% versus 10%); and were provided with discharge NRT (21% versus 4%). Conclusions Implementation of a multi-strategic intervention is effective in increasing hospital smoking care delivery, particularly the provision of NRT. Research is required to identify methods to increase further the delivery of this and other forms of smoking care. [source] Diversions and diversity: Does the personalisation agenda offer real opportunities for taking children's home literacies seriously?ENGLISH IN EDUCATION, Issue 2 2009Marilyn Mottram Abstract This paper argues that the current commitment to personalised learning opens up real opportunities for changing the language and practice of literacy teaching as it currently operates in England. We argue that there is a need to seize the opportunities currently on offer, to educate teachers differently and to develop classroom practice and pedagogies that acknowledge the complexities of children's lives and literacies. We draw on evidence from a year-long ethnographic research study, conducted between 2006,2007, of fourteen children and their families. The children attended the same inner city primary school in an area of urban regeneration characterised by high levels of economic deprivation, high crime and many social problems. The resulting evidence suggests that personalising learning becomes a reality when teachers are given space and time to develop their understanding of the uses and meaning of literacy in the communities they serve. [source] A European methodology for sustainable development strategy reviewsENVIRONMENTAL POLICY AND GOVERNANCE, Issue 2 2010Joachim H. Spangenberg Abstract In 2005 the EU Environment Directorate initiated the production of a guidebook for peer reviews of national sustainable development strategies (NSDSs), which was published in 2006. Its objective is to support EU member states planning to evaluate their respective NSDS, supporting and stimulating all potential participants. It describes how to initiate, start, lead and conclude an evaluation process, and suggests, based on European experiences, a spectrum of methods available for this purpose. During a Commission-sponsored trial period, 2006/2007, the Netherlands was the only country to make use of this offer. However, the renewed EU Sustainable Development Strategy (EUSDS) calls for regular (peer) reviews of NSDS. Using this specific review instrument is recommended as part of a mutual learning exercise, which might stimulate a self-organized convergence of NSDSs, and better vertical integration, without establishing new competences and mechanisms on the EU level. Two new elements are suggested, a simple ,pressure,policy matrix' (PPM), supporting comprehensiveness control, and the possibility of patchwork evaluations, based on the systematique of the matrix.

[source] Dealing with the offer of drugs: the experiences of a sample of pre-teenage schoolchildrenADDICTION, Issue 7 2003James McIntosh ABSTRACT Aims To investigate the ways in which pre-teenage children anticipate and deal with the offer of drugs. Design A qualitative study based on semi-structured interviews with 10,12-year-old schoolchildren. Setting The cities of Glasgow (Scotland) and Newcastle (England), UK. Participants A sample of 216 pre-teenage children. Forty-three had used drugs on at least one occasion, 42 had been offered but had not used drugs and 131 had neither used drugs nor been offered them. Most of the results reported in the paper relate to the experiences of the 42 children who had declined the offer of drugs. Findings While children who had not been exposed to drug offers expressed a high degree of confidence in their ability to deal with them, those who had actually had to cope with such offers experienced a variety of difficulties. The ease with which an offer could be declined appeared to depend upon two main factors: who was making the offer and the context in which it was being made. According to the children, offers from people with whom they had a close relationship and those in which pressure or encouragement were involved were particularly difficult to deal with. Conclusions The paper concludes that there is a need to equip young people better with the interpersonal tools they require to deal with the various situations they are likely to encounter in which drugs may be offered. It is suggested that a broadly based life skills approach to drug education may provide the best way of helping young people to deal with these situations.
