Marketing of fishing gear materials and fishing gear making in parts of Kainji Lake basin

The importance of fishing gear in fishing cannot be over-emphasized; as without it fish cannot be obtained. The method used to catch fish affects the condition in which the product is landed. This means that a bad-catching method would produced bad fish to the consumer. To achieve the goal of self-sufficiency in fish production in Nigeria, there is need to address the lingering problems of fishing gear and craft technology, especially in terms of availability of materials and their cost. The sale and making of fishing gear materials are two areas of fisheries, which are yet to be exploited by the general public as forms of businesses for livelihood. The study is conducted in villages around the lower part of Kainji Lake, towards the dam, including New Bussa. It reveals that only the fishermen themselves are involved in making their own fishing gears while those involved in the selling of fishing gear materials like the sheet netting, ropes, twines, floats, sinkers etc are business men and women who may not have any experience of fishing. Also considered in the study is the art of making fishing crafts like the canoe and gourd. Very few entrepreneurs are involved and they are so skilled that each is specialized in the making of only one kind of craft or gear

Enhancement of fish production in Borno State with extension services

Borno State possesses great potentials for fish production both from inland fisheries and aquaculture. The socio-economic and environmental production factors are suitable for fish production. If the potential of the State were well harnessed, it would be playing significant roles in achieving self-sufficiency in fish production in Nigeria. But the situation at the moment is that its fisheries potentials are not being optimally utilized. While the inland waters of Lake Chad are currently being recklessly exploited, aquaculture development is given little or no attention. It is evident that there is a missing link between research results and the potential end users. Because information in fish production variables is a pre-requisite for fisheries development, the gap that exists between two poles must be bridged, fisheries Extension provides this important link between research result and the end users of research findings. The paper examines the importance of extension services as the key to unlock fish production information that are usually consigned to the pages of academic journals and research publications

Trade and Management: Exclusive Economic Zones and the Changing Japanese Surimi Market

The United States' increasing competitive advantage in international seafood trade in Alaska walleye pollock. Theragra chalcogramma, has contributed to higher prices for surimi-based goods and structural changes in seafood production and trade in Japan. The objectives of this analytical investigation include: 1) Evaluation of the role reversal of Japan and the United States in international seafood trade and 2) quantification of the impact of rising prices of frozen surimi on household consumption of surimi-based foods in Japan. This study documents Japan's regression from "seafood self-sufficiency" to increasing dependence on imported products and raw materials. In particular, Japan's growing dependence on American fishermen and seafood producers is described. Surimi production by the United States, and its emerging dominance over Japanese sources of supply, are especially significant. Results of the analysis suggest that Japanese consumer demand for surimi-based food stuffs correlates directly with "competitive" food prices, e.g., pork, chicken, and beef, and inversely with personal income. Also revealed is how rising household income and relative price shifts among competing animal protein sources in the Japanese diet have contributed to declining household consumption of surimi-based foods, specifically, and a shift away from seafoods in favor of beef, in general. The linkages between, for example. Japanese domestic seafood production and consumption, international trade in marine products, and resource management decisions in the U.S. EEZ present a picture of a changing global marketplace. Increasingly, actions in one arena will have perhaps profound implications in the others.

Education in J.J. Rousseau: a methodological antecedent of competence based teaching

Taking into account the huge repercussion and influence that J.J. Rousseau has had on modern pedagogy, the recent tercentenary of his birth is a good opportunity to think about his outstanding relevance nowadays. This paper is a theoretical and educative research developed with an analytic and comparative hermeneutical method. The main objective is to show how some concepts of his philosophy of education have a great similarity with certain changes that the present competency based teaching is demanding, so it could be considered its methodological background. In order to achieve this objective this exposure has been divided in three parts. The first part is an analysis of Rousseau's educational theory as developed in the first three books of the Emilio, in which one of the main themes is self experience-based learning, fostering self-sufficiency, curiosity and the motivation for learning. Rousseau proposed as a method the negative education, which requires, among other conditions, a constant monitoring of the learner by the tutor. In the second part, a brief summary of the most relevant changes and characteristics of competency-based teaching is developed, as well as its purpose. The student’s participation and activity are highlighted within their own learning process through the carrying out of tasks. The new educational model involves a radical change in the curriculum, in which it is highlighted the transformation of the methodology used in the classroom as well as the role of the teacher. Finally, the aim of the third part is to offer a comparative synthesis of both proposals grouping the parallelisms found in 4 topics: origin of the two models, its aims, methodology, and change in the teaching roles.

‘What Adult Worker Model? A Critical Look at Recent Social Policy Reform in Europe from a Gender and Family Perspective

Analyses regularly feature claims that European welfare states are in the process of creating an adult worker model. The theoretical and empirical basis of this argument is examined here by looking first at the conceptual foundations of the adult worker model formulation and then at the extent to which social policy reform in western Europe fits with the argument. It is suggested that the adult worker formulation is under-specified. A framework incorporating four dimensions—the treatment of individuals vis-à-vis their family role and status for the purposes of social rights, the treatment of care, the treatment of the family as a social institution, and the extent to which gender inequality is problematized—is developed and then applied. The empirical analysis reveals a strong move towards individualization as social policy promotes and valorizes individual agency and self-sufficiency and shifts some childcare from the family. Yet evidence is also found of continued (albeit changed) familism. Rather than an unequivocal move to an individualized worker model then, a dual earner, gender-specialized, family arrangement is being promoted. The latter is the middle way between the old dependencies and the new “independence.” This makes for complexity and even ambiguity in policy, a manifestation of which is that reform within countries involves concurrent moves in several directions.

Cities Ready for Energy Crises - Building Urban energy Resilience

Various sources indicate that threats to modern cities lie in the availability of essential streams, among which energy. Most cities are strongly reliant on fossil fuels; not one case of a fully self-sufficient city is known. Engineering resilience is the rate at which a system returns to a single steady or cyclic state following a perturbation. Certain resilience, for the duration of a crisis, would improve the urban capability to survive such a period without drastic measures.
The capability of cities to prepare for and respond to energy crises in the near future is supported by greater or temporary self-sufficiency. The objective of the underlying research is a model for a city – including its surrounding rural area – that can sustain energy crises. Therefore, accurate monitoring of the current urban metabolism is needed for the use of energy. This can be used to pinpoint problem areas. Furthermore, a sustainable energy system is needed, in which the cycle is better closed. This will require a three-stepped approach of energy savings, energy exchange and sustainable energy generation. Essential is the capacity to store energy surpluses for periods of shortage (crises).
The paper discusses the need for resilient cities and the approach to make cities resilient to energy crises.

Oppositional Political Identity in the Song Culture of the Vormärz and the 1848 Revolution in Germany

Historically political song has often been perceived negatively, as a disturbance of the peace, summed up by the legendary line from Goethe’s Faust: “Politisches Lied – ein garstiges Lied”. In the period in Germany of the Vormärz (from 1815 up to the revolution of March 1848), however, we see how this perception may be changing as it increasingly becomes a means of self-expression in public life. This was the era of restauration, in which broader sections of German society are striving for political emancipation from the princes and kings. A whole host of political themes emerge in the songs (Freiheitslieder) of that period in which a new oppositional political consciousness is reflected. The themes range from freedom of speech, freedom from censorship, and the need for democratic and national self-determination to critiques of injustice and hunger, and parodies of political convention and opportunism. Sources of reception give indications about the social and political milieus in which these songs circulated. Such sources include broadsheets, handwritten manuscripts, song collections, commemoration events, advertisements in political press, memoires, police reports and general literature of the time. In many cases we see how these songs reflect the emerging social and political identities of those who sing them. One also sees the use of well known melodies in the popular dissemination of these songs. An intertextual function of music often becomes apparent in the practice of contrefacture whereby melodies with particular semantic associations are used to either underline the message or parody the subject of the song.

School's out forever: Postsecondary educational trajectories of students with autism

Objective:Postsecondary educational attainment is the key for successful transition to adulthood, economic self-sufficiency, and good mental and physical health.Method:Secondary analyses of school leavers’ data were carried out to establish postsecondary educational trajectories of students on the autism spectrum in the United Kingdom.Results:Findings show that students with autism who had attended mainstream secondary schools enter Further Education (post-16 vocational training) and Higher Education (University) institutions at a similar rate to other students to study the full range ofsubjects on offer. However, they are more likely to be younger, study at a lower academic level, and remain living at home.Conclusion:While course completion data were not yet available, attainment data showed that prospects were improving, although more needs to be done to enable these young adults to a achieving their post secondary educational potential.

La recherche de l’autosuffisance chez Aristote : la rencontre entre l’éthique et la politique

Ce mémoire vise à mieux comprendre l'utilisation du concept d'autarcie à l'oeuvre dans les écrits d'Aristote et, ce faisant, à nous amener à une meilleure compréhension du lien entre l'éthique et la politique dans la pensée aristotélicienne. Pour ce faire, nous commençons tout d'abord par distinguer deux types d'autarcie, à savoir ce que nous appellerons dans la suite l'autarcie divine et l'autarcie humaine. L'autarcie divine doit être comprise comme le fait de se suffire pleinement à soi-même de la manière la plus rigoureuse qui soit et cette autarcie n'est, à proprement parler, attribuable qu'au divin. L'autarcie humaine, quant à elle, est celle qui est à l'oeuvre dans la définition que donne Aristote de la cité, à savoir qu'elle est un regroupement autarcique de personnes visant à vivre et à bien vivre. Par la suite, nous montrons que la pratique de la philosophie, qui est décrite comme une pratique autarcique en EN, X, est difficilement conciliable avec les activités de la cité et la constitution d'une communauté politique. En effet, comme c'est le besoin qui doit jouer le rôle de ciment de la cité, il est difficile de voir comment la philosophie peut s'insérer dans le cadre étatique de la cité, étant donné qu'elle n'est d'aucune utilité et qu'elle est recherchée pour elle-même. Toutefois, puisqu'Aristote ne présente jamais la cohabitation de la philosophie avec les autres activités de la cité comme problématique, nous tentons de voir comment il est possible de concilier la pratique de la philosophie avec la nécessité pour l'individu de vivre en cité. C'est en examinant la notion de loisir que nous en venons à conclure que la philosophie doit y être reléguée afin de pouvoir être pratiquée. C'est aussi en associant la philosophie au loisir et en étudiant le rôle que celui-ci doit jouer au sein de la cité que nous sommes en mesure de voir se dessiner le lien entre l'éthique et la politique.

Les motivations des acteurs étatiques dans les interventions humanitaires : les États-Unis face aux cas du Rwanda (1994), du Kosovo (1999) et du Darfour (2003 à 2008)

Ce mémoire vise à comprendre les motivations des États à intervenir militairement dans un autre État pour mettre fin aux violations graves des droits de l’homme tel que le nettoyage ethnique et le génocide. Plus précisément, nous cherchons à comprendre pourquoi il y a eu une variation dans la position américaine face aux cas de génocide au Rwanda en 1994, au Kosovo en 1999 et au Darfour de 2003 à 2008. À partir d’une approche réaliste en Relations Internationales qui met l’accent sur l’intérêt national égoïste comme facteur principal explicatif du comportement des États, nous procédons à l’étude des cas de la position américaine lors de trois crises humanitaires. Plus précisément, nous cherchons à comprendre la non intervention des États-Unis lors du génocide des Tutsis au Rwanda en 1994, l’intervention américaine au Kosovo en 1999, et enfin la non intervention américaine au Darfour de 2003 à 2008. En somme, nos études de cas démontrent que c’est l’intérêt national qui motive les États d’intervenir ou de ne pas intervenir lors des cas de nettoyage ethnique ou de génocide. D’une part, lors du génocide des Tutsis au Rwanda en 1994, les États-Unis ne sont pas intervenus car l’intérêt national interprété comme le repli sur les affaires internes américaines ne serait pas maximisé par l’intervention militaire. Ensuite, l’intervention des États-Unis et de l’OTAN au Kosovo en 1999 est expliquée par l’intérêt national américain dans un contexte de l’après guerre froide d’approfondir son engagement sécuritaire en Europe et de préserver sa position hégémonique et son prestige sur la scène internationale, d’assurer la stabilité régionale et de préserver la crédibilité de l’OTAN. Finalement, l’intérêt national défini en termes de sécurité dans un contexte de la guerre au terrorisme explique la non intervention américaine au Darfour de 2003 à 2008.

Sustainability of Small Scale Farming in a Mountain Region: Case Study of the Khaling Rai Population of the Solukhumbu, Nepal

The Khaling Rai live in a remote area of the mountain region of Nepal. Subsistence farming is central to their livelihood strategy, the sustainability of which was examined in this study. The sustainable livelihood approach was identified as a suitable theoretical framework to analyse the assets of the Khaling Rai. A baseline study was conducted using indicators to assess the outcome of the livelihood strategies under the three pillars of sustainability – economic, social and environmental. Relationships between key factors were analysed. The outcome showed that farming fulfils their basic need of food security, with self-sufficiency in terms of seeds, organic fertilisers and tools. Agriculture is almost totally non-monitized: crops are grown mainly for household consumption. However, the crux faced by the Khaling Rai community is the need to develop high value cash crops in order to improve their livelihoods while at the same time maintaining food security. Institutional support in this regard was found to be lacking. At the same time there is declining soil fertility and an expanding population, which results in smaller land holdings. The capacity to absorb risk is inhibited by the small size of the resource base and access only to small local markets. A two-pronged approach is recommended. Firstly, the formation of agricultural cooperative associations in the area. Secondly, through them the selection of key personnel to be put forward for training in the adoption of improved low-cost technologies for staple crops and in the introduction of appropriate new cash crops.
