The efficacy of non-pharmacological interventions in the management of procedural pain in preterm and term neonates. A systematic literature review

BACKGROUND: Neonates in a neonatal intensive care unit are exposed to a high number of painful procedures. Since repeated and sustained pain can have consequences for the neurological and behaviour-oriented development of the newborn, the greatest attention needs to be paid to systematic pain management in neonatology. Non-pharmacological treatment methods are being increasingly discussed with regard to pain prevention and relief either alone or in combination with pharmacological treatment. AIMS: To identify effective non-pharmacological interventions with regard to procedural pain in neonates. METHODS: A literature search was conducted via the MedLine, CINAHL, Cochrane Library databases and complemented by a handsearch. The literature search covered the period from 1984 to 2004. Data were extracted according to pre-defined criteria by two independent reviewers and methodological quality was assessed. RESULTS: 13 randomised controlled studies and two meta-analyses were taken into consideration with regard to the question of current nursing practice of non-pharmacological pain management methods. The selected interventions were "non-nutritive sucking", "music", "swaddling", "positioning", "olfactory and multisensorial stimulation", "kangaroo care" and "maternal touch". There is evidence that the methods of "non-nutritive sucking", "swaddling" and "facilitated tucking" do have a pain-alleviating effect on neonates. CONCLUSIONS: Some of the non-pharmacological interventions have an evident favourable effect on pulse rate, respiration and oxygen saturation, on the reduction of motor activity, and on the excitation states after invasive measures. However, unambiguous evidence of this still remains to be presented. Further research should emphasise the use of validated pain assessment instruments for the evaluation of the pain-alleviating effect of non-pharmacological interventions.

経済成長と貧困・雇用：Pro-Poor Growth論の系譜

開発途上国が長期的に貧困削減を実現していくためには、貧困削減に貢献する形で経済成長をすることが必要であり、貧困削減に親和的な経済成長がPro-Poor Growthと呼ばれている。現在までのところ、Pro-Poor Growth研究は、どの国のどの時期の経済成長が貧困削減に大きく貢献したかを問うものが多数を占めており、何がpro-poor growthをもたらすか、に着目した研究は少ない。その少ない研究の多くは農業や農村経済の役割に期待するものであるが、本稿では、既にある程度の貧困削減を遂げた東・東南アジアの経験に鑑み、低賃金の国において労働集約的製造業品を輸出することで貧困層の賃金や雇用機会を飛躍的に伸張させる可能性について考察した。バングラデシュ、カンボジアといった国々は既に縫製業がその役割を果たしており、これまでの東・東南アジアの貧困削減パターンが現在の東南アジアや南アジアの最貧国でも踏襲される可能性が十分にある。

A real-time asymmetric multiprocessor-reconfigurable system-on-chip architecture

We propose an asymmetric multi-processor SoC architecture, featuring a master CPU running uClinux, and multiple loosely-coupled slave CPUs running real-time threads assigned by the master CPU. Real-time SoC architectures often demand a compromise between a generic platform for different applications, and application-specific customizations to achieve performance requirements. Our proposed architecture offers a generic platform running a conventional embedded operating system providing a traditional software-oriented development approach, while multiple slave CPUs act as a dedicated independent real-time threads execution unit running in parallel of master CPU to achieve performance requirements. In this paper, the architecture is described, including the application / threading development environment. The performance of the architecture with several standard benchmark routines is also analysed.

Modeling and validating dynamic adaptation

This paper discusses preliminary work on modeling and validation dynamic adaptation. The proposed approach is on the use of aspect-oriented modeling (AOM) and models at runtime. Our approach covers design and runtime phases. At design-time, a base model and different variant architecture models are designed and the adaptation model is built. Crucially, the adaptation model includes invariant properties and constraints that allow the validation of the adaptation rules before execution. During runtime, the adaptation model is processed to produce a correct system configuration that can be executed.

Dynamic variability in adaptive systems

One of the reasons for using variability in the software product line (SPL) approach (see Apel et al., 2006; Figueiredo et al., 2008; Kastner et al., 2007; Mezini & Ostermann, 2004) is to delay a design decision (Svahnberg et al., 2005). Instead of deciding on what system to develop in advance, with the SPL approach a set of components and a reference architecture are specified and implemented (during domain engineering, see Czarnecki & Eisenecker, 2000) out of which individual systems are composed at a later stage (during application engineering, see Czarnecki & Eisenecker, 2000). By postponing the design decisions in such a manner, it is possible to better fit the resultant system in its intended environment, for instance, to allow selection of the system interaction mode to be made after the customers have purchased particular hardware, such as a PDA vs. a laptop. Such variability is expressed through variation points which are locations in a software-based system where choices are available for defining a specific instance of a system (Svahnberg et al., 2005). Until recently it had sufficed to postpone committing to a specific system instance till before the system runtime. However, in the recent years the use and expectations of software systems in human society has undergone significant changes.Today's software systems need to be always available, highly interactive, and able to continuously adapt according to the varying environment conditions, user characteristics and characteristics of other systems that interact with them. Such systems, called adaptive systems, are expected to be long-lived and able to undertake adaptations with little or no human intervention (Cheng et al., 2009). Therefore, the variability now needs to be present also at system runtime, which leads to the emergence of a new type of system: adaptive systems with dynamic variability.

Database evolution on an orthogonal persistent programming system: A semi-transparent approach

In this paper the problem of the evolution of an object-oriented database in the context of orthogonal persistent programming systems is addressed. We have observed two characteristics in that type of systems that offer particular conditions to implement the evolution in a semi-transparent fashion. That transparency can further be enhanced with the obliviousness provided by the Aspect-Oriented Programming techniques. Was conceived a meta-model and developed a prototype to test the feasibility of our approach. The system allows programs, written to a schema, access semi-transparently to data in other versions of the schema.

Développement d’un indice du potentiel TOD pour l’agglomération de Montréal

Résumé : Les aménagements axés sur le transport en commun (transit-oriented development ou TOD) reposent sur la création de développements résidentiels à proximité d’un nœud de transport existant. Dans le cadre de cet essai, on cherche plutôt à identifier les quartiers existants de Montréal possédant déjà les caractéristiques propices à l’aménagement d’un TOD, mais mal desservis par les transports en commun. En s’inspirant d’une étude menée aux Pays-Bas, on a eu recours à une analyse spatiale multicritères afin de concevoir un «indice du potentiel TOD», comportant quatre critères jugés essentiels, soit : la densité d’habitants, la mixité des utilisations du sol, la mixité sociale, ainsi que la distance aux transports. Malgré la difficulté d’intégrer l’ensemble des critères identifiés dans la littérature, les résultats révèlent un fort potentiel TOD sur le Plateau Mont-Royal, dans le Sud-Ouest, Hochelaga-Maisonneuve et plus particulièrement dans Anjou et Saint-Michel. On recommande notamment un secteur situé dans Saint-Michel, dont le potentiel TOD pourrait être enrichi par la création de plus fortes connexions au réseau de transports en commun.

Turystyka i rekreacja a jakość życia mieszkańców Leszna

The quality of life (QOL) is currently one of the main fields of study for researchers around the world. Its complex nature makes it a topic of interest for many different fields, such as philosophy, ethics, medicine, economics, sociology and physical culture sciences. Despite the differences in the way various researches define the QOL, the general agreement is that any measurement of QOL should encompass the following dimensions: objective QOL and subjective QOL (well-being). Particularly noteworthy, for any complex research is the mutual relationship between the QOL and tourism and recreation. The increase of tourism and recreation should entail a simultaneous development of local communities, as emphasized by Crouch and Ritchie this implies that the inhabitants of an area that serves a function of tourism and recreation should profit from the increased number of tourists. This benefits should be reflected in the objective QOL conditions and the subjective sense of satisfaction of the residents. The city of Leszno and it’s tourism and recreation-oriented development strategy were used to form a basis for theoretical study on QOL and to calculate the Tourism-Recreation QOL Index.

THE INFLUENCE OF URBAN FORM AT DIFFERENT GEOGRAPHICAL SCALES ON TRAVEL BEHAVIOR; EVIDENCE FROM U.S. CITIES

Suburban lifestyle is popular among American families, although it has been criticized for encouraging automobile use through longer commutes, causing heavy traffic congestion, and destroying open spaces (Handy, 2005). It is a serious concern that people living in low-density suburban areas suffer from high automobile dependency and lower rates of daily physical activity, both of which result in social, environmental and health-related costs. In response to such concerns, researchers have investigated the inter-relationships between urban land-use pattern and travel behavior within the last few decades and suggested that land-use planning can play a significant role in changing travel behavior in the long-term. However, debates regarding the magnitude and efficiency of the effects of land-use on travel patterns have been contentious over the years. Changes in built-environment patterns is potentially considered a long-term panacea for automobile dependency and traffic congestion, despite some researchers arguing that the effects of land-use on travel behavior are minor, if any. It is still not clear why the estimated impact is different in urban areas and how effective a proposed land-use change/policy is in changing certain travel behavior. This knowledge gap has made it difficult for decision-makers to evaluate land-use plans and policies. In addition, little is known about the influence of the large-scale built environment. In the present dissertation, advanced spatial-statistical tools have been employed to better understand and analyze these impacts at different scales, along with analyzing transit-oriented development policy at both small and large scales. The objective of this research is to: (1) develop scalable and consistent measures of the overall physical form of metropolitan areas; (2) re-examine the effects of built-environment factors at different hierarchical scales on travel behavior, and, in particular, on vehicle miles traveled (VMT) and car ownership; and (3) investigate the effects of transit-oriented development on travel behavior. The findings show that changes in built-environment at both local and regional levels could be very influential in changing travel behavior. Specifically, the promotion of compact, mixed-use built environment with well-connected street networks reduces VMT and car ownership, resulting in less traffic congestion, air pollution, and energy consumption.
