Purpose. To determine whether Australia's Walk to Work Day media campaign resulted in behavioural change among targeted groups. Methods. Pre- and postcampaign telephone surveys of a cohort of adults aged 18 to 65 years (n = 1100, 55% response rate) were randomly sampled from Australian major melropolitan areas. Tests for dependent samples were applied (McNemax chi(2) or paired t-test). Results. Among participants who did not usually actively commute to work was a significant decrease in car only use an increase in walking combined with public transport. Among those who were employed was a significant increase in total time walking (+16 min/wk; t [780] = 2.04, p < .05) and in other moderate physical activity (+120 min/wk; t [1087] = 4.76, p < .005), resulting in a significant decrease in the proportion who were inactive (chi(2) (1) = 6.1, p < .05). Conclusion. Although nonexperimental, the Walk to Work Day initiative elicited short-term changes in targeted behaviors among target groups. Reinforcement by integrating worksite health promotion strategies may be required for sustained effects.

Esta dissertação procurou apreender que consciência, ou consciências, formaram as Comunidades Eclesiais de Base CEBs com a apropriação das orientações da Educação Popular e da Teologia da Libertação durante o Regime Militar brasileiro. Entretanto, diferente da maioria dos trabalhos que se voltam a essa experiência, o estudo elaborou uma abordagem que as colocaram em prismas diversos. Focalizou, inicialmente, o momento histórico e algumas experiências nos vinte anos de regime e, em seguida, a Educação Popular e a Teologia da Libertação (teoria e prática), objetivando compreender seus projetos político-pedagógicos. A reflexão sobre a Educação Popular e a Teologia da Libertação aliada à reconstituição histórica do período forneceram o contexto no qual se inseriu a análise pretendida: a observação do fenômeno educacional numa perspectiva de micro-análise retratando os processos sociais e as experiências vividas para conhecer a consciência que emergiu de tal experiência educacional. Neste sentido, a pesquisa inferiu, por meio da análise de uma comunidade em particular, que a consciência nascida de tal prática foi de curto alcance, uma vez que os sujeitos envolvidos nesse projeto conscientizador perceberam apenas a ausência imediata de direitos.(AU)

O objectivo principal deste estudo é tentar identificar as possibilidades de melhoria das interfaces físicas das consolas centrais dos automóveis, e a sua ergonomia e usabilidade enquanto meio de realização de tarefas dentro do veículo, de modo a contribuir para melhorar a experiência e a segurança na condução. Neste estudo é feita uma investigação acerca de algumas das interfaces físicas das consolas centrais, medindo o seu desempenho no que diz respeito à distracção do condutor e facilidade de uso em situações de dupla tarefa. Para isso foi adaptado um simulador de condução, e uma bateria de testes de situações de dupla tarefa foi efectuada, de modo a obter dados de telemetria de condução e de desempenho de cada interface da consola central. Os dados obtidos acerca da trajectória do veículo e da sua comparação com trajectórias de referência e a velocidade média nos sectores de condução, foram comparados com dados de desvio de olhar, e que por sua vez sã o comparados e relacionados com os dados de percepção própria do condutor, obtidos através dos testes subjectivos de auto-percepção NASA - Administração Nacional da Aeronáutica e do Espaço - Raw Task Load Index (NASA RTLX). É esperado que desta análise possam ser encontradas algumas conclusões que deverão indicar oportunidades de melhoria às interfaces das consolas centrais, que possam resultar de uma combinação ou divisão dos sistemas, ou que abram caminho ao desenvolvimento de novas soluções alternativas, ou até à criação de um guia de boas práticas para o futuro design e desenvolvimento de interfaces de consolas centrais para automóveis.

Using comparable plant-level surveys we demonstrate significant differences between the determinants of export performance among the UK and German manufacturing plants. Product innovation, however measured, has a strong effect on the probability and propensity to export in both countries. Being innovative is positively related to export probability in both countries. In the UK the scale of plants’ innovation activity is also related positively to export propensity. In Germany, however, where levels of innovation intensity are higher but the proportion of sales attributable to new products is lower, there is some evidence of a negative relationship between the scale of innovation activity and export performance. Significant differences are identified between innovative and non-innovative plants, especially in their absorption of spill-over effects. Innovative UK plants are more effective in their ability to exploit spill-overs from the innovation activities of companies in the same sector. In Germany, by contrast, non-innovators are more likely to absorb regional and supply-chain spill-over effects. Co-location to other innovative firms is generally found to discourage exporting.

Angiotensin I and II have been shown to directly induce protein degradation in skeletal muscle through an increased activity and expression of the ubiquitin-proteasome proteolytic pathway. This investigation determines the role of the nuclear transcription factor nuclear factor-κB (NF-κB) in this process. Using murine myotubes as a surrogate model system both angiotensin I and II were found to induce activation of protein kinase C (PKC), with a parabolic dose-response curve similar to the induction of total protein degradation. Activation of PKC was required for the induction of proteasome expression, since calphostin C, a highly specific inhibitor of PKC, attenuated both the increase in total protein degradation and in proteasome expression and functional activity increased by angiotensin II. PKC is known to activate I-κB kinase (IKK), which is responsible for the phosphorylation and subsequent degradation of I-κB. Both angiotensin I and II induced an early decrease in cytoplasmic I-κB levels followed by nuclear accumulation of NF-κB. Using an NF-κB luciferase construct this was shown to increase transcriptional activation of NF-κB regulated genes. Maximal luciferase expression was seen at the same concentrations of angiotensin I/II as those inducing protein degradation. Total protein degradation induced by both angiotensin I and II was attenuated by resveratrol, which prevented nuclear accumulation of NF-κB, confirming that activation of NF-κB was responsible for the increased protein degradation. These results suggest that induction of proteasome expression by angiotensin I/II involves a signalling pathway involving PKC and NF-κB. © 2005 Elsevier Inc. All rights reserved.

Single cell recordings in monkeys support the notion that the lateral prefrontal cortex (PFC) controls reactivation of visual working memory representations when rehearsal is disrupted. In contrast, recent fMRI findings yielded a double dissociation for PFC and the medial temporal lobe (MTL) in a letter working memory task. PFC was engaged in interference protection during reactivation while MTL was prominently involved in the retrieval of the letter representations. We present event-related potential data (ERP) that support PFC involvement in the top-down control of reactivation during a visual working memory task with endogenously triggered recovery after visual interference. A differentiating view is proposed for the role of PFC in working memory with respect to endogenous/exogenous control and to stimulus type. General implications for binding and retention mechanisms are discussed.

A gazdaság növekedés felgyorsulása hosszú távon először szükségszerűen csak egy rövid helyreállítási perióduson keresztül valósulhat meg, amelynek során a növekedés ütemét a válságok miatt elmaradt vagy más okból elmulasztott növekedés pótlása gyorsítja fel. Ez azonban messze nem jelenti a hosszú távú növekedési ütem felgyorsulását. A jelenséget először Jánossy Ferenc írta le, akinek megállapításai ma is érvényesek: egy jelentős visszaesés, majd stagnálás után a növekedési ütem 2005 után visszaállt az 1980 óta kialakult 1,5 százalékos hosszú távú ütemre. A Jánossy-féle szakmastruktúra-tényező nem más, mint a tudástőke: a munkaképes lakosság személyes tudása, jártassága és motivációja. Ezek az összetevők egy újrafogalmazott termelési függvény emberi elemei számos új és már korábban is ismert tényező mellett. Az emberi erőforrások nyilvántartása nem kompetenciaalapú, és emiatt a hosszú távú növekedési ütem alacsony szintjét sem tudjuk megmagyarázni. A növekedési ütem ingadozásai mögött elsősorban gazdaságpolitikai hibákat, érdemeket keresünk, holott az emberi beruházások elégtelen szintje jelenti a problémát, amely a múlt örökségnek és a jelen terheinek súlya alatt nem oldódik meg automatikusan. A magyar gazdaság egy újabb helyreállítási periódus előtt áll, s a gazdasági átalakítás alapvető feladata a foglalkoztatható lakosság aktivizálása, enélkül minden növekedési gyorsulás csak átmeneti helyreállítási periódus marad. JEL kód: B23, C22, E01, O11. /===/ Acceleration of economic growth in the long term can primarily be achieved only through a short period of consolidation, in which the growth rate of growth by recession or made up for by growth potential neglected for other reasons. But this is far from equivalent to an acceleration of the long-term growth rate. The phenomenon was described first by Ferenc Jánossy, whose conclusions remain valid to this day: after a substantial slump and a period of stagnation, the growth rate recovered after 2005 the long-term rate of 1.5 per cent that had set in after 1980. Jánossy's trade structure factor amounts to capital in knowledge: the personal know-how, expertise and motivation of the able-bodied population. These factors are the human constituents of a newly formulated production function, along with numerous new and previously known factors. The registration of human resources is competence- based and so it cannot explain the low level of the long-term growth rate either. People tend primarily to see failures and achievements of economic policy behind the failures and achievements of economic policy, when the real problem is inadequate human investment, which will not resolve itself automatically under the weight of the past and present burdens. The Hungarian economy is on the brink of a new period of recovery, and the basic task of economic transformation is to activate the employable population, without which any acceleration of growth will amount only to a temporary period of recovery.

Arra törekszünk, hogy többtényezős leírás keretében bemutassuk a középkori Európa genezisét. Európa kialakulását a latin kereszténység kibontakozásával azonosítjuk, s megkíséreljük bemutatni, ahogyan az európai civilizáció a Kr.u. 3–10. században fokozatosan maga mögött hagyta a klasszikus ókor világát. Külön súlyt helyezünk a latin keresztény kultúrkör kialakulásának térbeli összefüggéseire. Megközelítésünk ötvözni szeretné a két világháború közötti polgári és keresztény humanista történetírás – Reynold és Dawson – törekvéseit a második világháború utáni gazdaság- és társadalomtörténet – leginkább az Annales-iskola – eredményeivel. Bár nincs módunk az érett középkor kialakulásához vezető valamennyi történeti tényező bemutatására, mégis arra törekszünk, hogy összefüggő képbe integráljuk a legfontosabb szempontokat. Az így felvázolt kép – reményeink szerint – a klasszikus értelemben vett pozitivista empirikus történetírás és a metahistóriai gondolkodásmód között félúton helyezkedik el.

Pediatric musculoskeletal trauma accounts for most childhood injuries. The anatomy and physiology of the pediatric skeleton is unique as is its response to trauma. The pediatric skeleton has periods of rapid growth; therefore the effect of trauma to the musculoskeletal system may have significant long-term complications.

In their discussion entitled - “Unfair” Restaurant Reviews: To Sue Or Not To Sue - by John Schroeder and Bruce Lazarus, Assistant Professors, Department of Restaurant, Hotel and Institutional Management at Purdue University, the authors initially state: “Both advantages and disadvantages exist on bringing lawsuits against restaurant critics who write “unfair” reviews. The authors, both of whom have experience with restaurant criticism, offer practical advice on what realistically can be done by the restaurateur outside of the courtroom to combat unfair criticism.” Well, this is going to be a sticky wicket no matter how you try to defend it, reviews being what they are; very subjective pieces of opinionated journalism, especially in the food industry. And, of course, unless you can prove malicious intent there really is no a basis for a libel suit. So, a restaurateur is at the mercy of written opinion and the press. “Libel is the written or published form of slander which is the statement of false remarks that may damage the reputation of others. It also includes any false and malicious publication which may damage a person's business, trade, or employment,” is the defined form of the law provided by the authors. Anecdotally, Schroeder and Lazarus offer a few of the more scathing pieces reviewers have written about particular eating establishments. And, yes, they can be a bit comical, unless you are the owner of an establishment that appears in the crosshairs of such a reviewer. A bad review can kneecap even a popular eatery. “Because of the large readership of restaurant reviews in the publication (consumer dining out habits indicate that nearly 50 percent of consumers read a review before visiting a new restaurant) your business begins a very dangerous downward tailspin,” the authors reveal, with attribution. “Many restaurant operators contend that a bad review can cost them an immediate trade loss of upward of 50 percent,” Schroeder and Lazarus warn. “The United States Supreme Court has ruled that a restaurant owner can collect damages only if he proves that the statement or statements were made with “actual malice,” even if the statements were untrue,” the authors say by way of citation. And that last portion of the statement cannot be over-emphasized. The first amendment to the U.S. Constitution does wield a heavy hammer, indeed, and it should. So, what recourse does a restaurateur have? The authors cautiously give a guarded thumbs-up to a lawsuit, but you better be prepared to prove a misstatement of fact, as opposed to the distinguishable press protected right of opinion. For the restaurateur the pitfalls are many, the rewards few and far between, Schroeder and Lazarus will have you know. “…after weighing the advantages and disadvantages of a lawsuit against a critic...the disadvantages are overwhelming,” the authors say. “Chicago restaurant critic James Ward said that someone dumped a load of manure on his yard accompanied by a note that read - Stop writing that s--t! - after he wrote a review of a local restaurant.” Such is a novel if not legally measurable tack against an un-mutual review.
