Responsive Open Learning Environments at the Open University

Personal Learning Environments (PLEs) offer new opportunities for supporting personalized and self regulated learning both in formal and in informal education. The Open University in the UK is an early adopter of PLEs through a number of different initiatives, one of which is the European project ROLE (Responsive Open Learning Environments). This paper presents some of the lessons learned and best practices from the introduction of ROLE technologies within an informal learning test-bed at the Open University

Pesticides Handling Practices Among Potato Growers in Kavrepalanchok, Nepal

The rate of pesticide application in the agricultural field is surging. Farmers are getting exposed to pesticide hazards from the misuse and unsafe handling of pesticides. The study was conducted among 101 potato growers in Kaverpalanchok district of Nepal in 2018. The objective of the study was to assess the knowledge, status, and pesticide handling practices among potato growers. Around 94% farmers applied pesticides against early and late blight. Only 5% growers treated seed before potato sowing. About 93 and 73% farmers sprayed pesticides 2-10 times/season into the field and spent 2-6 hours/pesticide spray respectively. More than 2/3rd growers did not read the pesticide labels, and nearly 95% growers received information on pesticide applications from agrovet rather than authorized government bodies. Only 13% farmers had received Integrated Pest Management (IPM) training. However, 1/4th of them had practiced IPM techniques. The majority of the growers used masks, rubber boots, and long-sleeved clothes during pesticide handling. Nearly 2/3rd growers threw pesticide containers anywhere in the environment. Concerned authorities should provide IPM training, skill-building programs on pesticide handling and awareness on waiting period and environmental hazards to avoid pesticide risk

Medium practices

In this essay I develop a topic addressed in my book, Film Art Phenomena: the question of medium specificity. Rosalind Krauss's essay 'Art In the Age of the Post-Medium Condition' has catalysed a move away from medium specificity to hybridity. I propose that questions of medium cannot be ignored, since they carry their own history and give rise to specific formal traits and possibilities. The research involves close critical analysis of four moving image works that have not previously been written about: two made with film, and one each with computer and mobile phone. The analyses are conducted by reference to my ideas about how technological peculiarities inform and inflect practice: I see the work's material composition, its form and final meaning as intricately bound up with each other. Film, video and the computer give rise to specific forms of moving image, partly because artists exploit a medium’s peculiarities, and because certain media lend themselves to some methodologies and not others. I do not seek hard distinctions between these media, but discuss them in terms of predispositions. For example, I discuss a 16mm cine film in which the shifting visibility of grain raises ideas around movement and stillness. The aim is to develop a definition of medium specificity, in relation to the moving image, that is not essentialist in the way previous versions were criticised for being, that is, based on ideas of "material substrate" (Wollen). I argue that film is a medium of stages, in contrast to the modern tapeless camcorder, in which all functions of recording, storage, playback and even editing are contained in a single device. Supported by a travel grant, I presented a version of this essay at the International Conference of Experimental Media Congress, Toronto, in April 2011, along with a selection of works: http://www.experimentalcongress.org/full-schedule

Practices of Art

Starting out from the ontology of human work set out by Marx in Das Kapital, the paper seeks to analyse the relations between the artist and his actions and aims, the work of art he produces, and the audience for this work. The paper concludes with a discussion of the problem of creativity in the arts, drawing on ideas of Roman Ingarden and other phenomenologists

Gendered Practices of Counterinsurgency

Current US counterinsurgency doctrine is gendered diversely in the different geographic locations where it is formulated, put in practice, and experienced. Where Iraqi and Afghan populations are subjected to counterinsurgency and its attendant development policy, spaces are made legible in gendered ways, and people are targeted – for violence or ‘nation-building’ – on the basis of gender-categorisation. Second, this gendering takes its most incendiary form in the seam of encounter between counterinsurgent foot-soldiers and the locals, where sexuality is weaponised and gender is most starkly cross-hatched with class and race. Finally, in the Metropole, new masculinities and femininities are forged in the domain of counterinsurgency policymaking: While new soldier-scholars represent a softened masculinity, counterinsurgent women increasingly become visible in policy circles, with both using ostensibly feminist justifications for their involvement

Practices

We examine an economy where professionals provide services to clients and where a professional can sell his practice to another. Professionals vary in quality, and clients in their need (or willingness-to-pay) for high-quality service. efficiency is measured as the number of matches between high-quality professionals and high-need clients. However, agent types are unobservable a priori. We find that trade in practices can facilitate the transmission of information about agent types; sometimes full efficiency is achieved. In cases where it is not, a tax on the sale of practices (based on the seller's age) can be used to achieve full efficiency. In addition, a ceiling on the price of services can be used to adjust the distribution of surplus between clients and professionals, while preserving efficiency.signaling, professional services, practices, goodwill
