The concept of the ‘active school’ emerged a decade ago as the role with increasing recognition of the role of schools in the promotion of physical activity. The purpose of this paper is to present the findings of a study which, drawing on Cale’s ‘Active School’ model, aimed to compare the nature and extent of physical activity promotion in secondary schools in three European regions. In so doing, it aimed to establish whether there were cultural differences in the strategies and approaches adopted by schools. [less ▲]

Our study focused on an analysis of secondary schools which were renowned for placing a real emphasis on physical education, sport and/or active lifestyles. The originality of this research lies in the fact that the study represents a comparison of schools from three different cultures in Europe. Our purpose was to determine whether the students were aware of the role their secondary school played in promoting an active lifestyle and influencing their physical activity levels. The findings should provide useful feedback to practitioners in terms of both their current and future practice. [less ▲]

Anxiety and sexual arousal have often been considered as incompatible. Since the end of the 20th Century, however, researches have impaired theories centred on the inhibitory effect of the stress and on peripheral explanations; they rather focus attention on the complexity of the relations between the two states and on cognitive mechanisms. <br />Now sexual arousal tends to be regarded as a complex response that requires the convergent interpretation of internal and external stimuli. Anxiety may have different effects on this process, sometimes neutral, sometimes facilitating and sometimes inhibitory. <br />On the one hand, anxiety can trigger a vegetative emotional reaction that may be associated to a concomitant erotic stimulation. Thus, anxiety facilitates the sexual response: this can be called a priming effect. This effect is regularly observed in labs, mainly among women. It likely also works in certain compulsive sexual behaviours or, more commonly, in those numerous persons that report being sexually aroused when stressed. <br />On the other hand, anxiety can cause a massive irruption of non erotic cues in working memory. Therefore, cognitive function available for treating erotic stimuli is diminished and sexual response is impaired. This is an effect of cognitive interference. A trait called erotophobia could be regarded as a vulnerability factor to cognitive interference. Erotophobic subjects are characterized by a trend to focus upon danger-related information when they are in a sexual situation and by a higher risk of sexual dysfunction. [less ▲]

Researches currently lead by experts of agriculture can be brought together in three fields: the globalization of agriculture and food and their impacts on food-processing systems, feeding the planet tomorrow and developing an agriculture which could face climatic, energetic and environmental stakes. Those three problematics cannot leave geographers cold, especially since those three fields show strong regional variations. So everything speaks in favour of geographers’ reinvestment in the field of agriculture’s geography, which has been widely neglected these last years. [less ▲]

This paper explores a participatory monitoring process initiated in Kampong Thom province with 3 Community Forestry (CF) sites where CF development was facilitated by Forestry Administration (FA) staff and externally supported by German Technical Support-Rural Development Programme (GTZ-RDP).The paper details the methodology used and the key outputs produced during the process, it highlights the four main principles of the principle, criteria, and indicator Monitoring and Evaluation (M&E) which are: (1) that forest health is maintained, (2) public well-being is improved, (3) community well-being is assured, and (4) external support is effective. The results show that in all three CF, the land integrity and the forest resource itself was improved between the baseline and follow-up surveys. Despite the positive results, many of the challenges and limitations were acknowledged including the difficulty in capturing all different points of view and opinions when there are such a large number of people involved and consulted as well as how this can lead to a slowdown within the whole process and is very expensive. The paper concludes suggesting that a local level monitoring system can help to build local capacity, improve decision-making, reduce conflict between local forest dependents and responsible authorities as well as empower local community members, especially marginalized groups.

We propose a generic method for obtaining quickly good upper bounds on the minimal value of a multistage stochastic program. The method is based on the simulation of a feasible decision policy, synthesized by a strategy relying on any scenario tree approximation from stochastic programming and on supervised learning techniques from machine learning.

During the last decades, the production of endocrine disrupting chemicals reached such elevated levels that they are now spread all over the environment. Endocrine disrupting chemicals are known to be very slowly degraded, decreasing the environmental quality and causing ecological risks. Marine mammals inhabiting polluted environments accumulate high quantities of these chemicals, and are good indicators of marine pollution Thirteen major organochloride pollutants (known from literature to contaminate north sea porpoise) were chosen in this study – o,p’-DDD; p,p’-DDD; p,p’-DDE; o,p’-DDT; p,p’-DDT; HCB; α-HCH; β-HCH; γ-HCH; δ-HCH; PCB 138; PCB 153 and PCB 180. The thirteen chemicals were tested individually and in mixtures by the use of report gene expression assays. The MCF7-ERE cells used in the assays were originated from MCF7 human mammary tumor cells transfected with the ERE-luciferase reporter system. Preliminary results suggest that o,p’-DDD; p,p’-DDD; o,p’-DDT; HCB; β-HCH; δ-HCH; PCB 138 and PCB 180 are able to stimulate the luciferase expression of MCF7-ERE cells when they are present individually or in mixtures. No synergism was observed within mixtures. When MCF7-ERE cells were exposed to the chemicals and 17β-oestradiol simultaneously, p,p’-DDE; α-HCH; PCB 138 and PCB 180 could raise the luciferase expression in comparison to the exposition of 17β-oestradiol alone; on the other hand, o,p’-DDD; p,p’-DDT; HCB; β-HCH; γ-HCH and δ-HCH seem to inhibit the luciferase expression at low doses. In the next step, the pollutants will be searched and quantified in the blubber tissue of porpoises by use of gas chromatography-mass spectrometry. The blubber tissue samples will also have their endocrine disrupting effects characterized. This work is ongoing and It is expected a relevant level of these compounds to be found in the samples. Conversely, their endocrine disrupting effects and how they act in agonist, antagonist ways are subject that still needs to be studied. [less ▲]

Endocrine disrupters are molecules able to interfere with the endocrine system and are largely spread in the environment. The evaluation of the estrogenic activity of some of these substances by reporter gene assays was the first aim of this paper. The substances chosen are also persistent organic pollutants (POP), which are capable to bioaccumulate in several organisms. Then, the occurrence of these substances was evaluated in the blubber tissue of North Sea harbour porpoises (Phocoena phocoena). Harbour porpoises are good indicators of the environmental contamination and therefore of seafood by POP. These POP were quantified by GC-MS and also by reporter gene assays. For the achievement of these aims, different analytical methods were developed. The following raking is proposed for the studied substances, according to their estrogenic activity: o,p’-DDT > o,p’-DDD > β-HCH > p,p’-DDT > p,p’-DDD > p,p’-DDE > δ-HCH > PCB 138 > γ-HCH > α-HCH > PCB 153 > HCB > PCB 180. None of them presented anti-estrogenic activity. The analysed samples presented high levels of POP, sometimes associated with estrogenic activity, confirming the occurrence of endocrine disruptors in these animals. [less ▲]
