Aktiiviseen kansalaisuuteen kasvattaminen yläkoulun maantieteen opetuksessa

Tutkielmassa tarkasteltiin aktiivista kansalaisuutta perusopetuksen yläkoulun (luokat 7–9) maantieteen opetuksessa. Tutkielman taustana olivat aktiiviseen kansalaisuuteen liittyvät viralliset ja epäviralliset diskurssit: opetussuunnitelman perusteiden aihekokonaisuudet, kouluun kohdistuvat kansalaiskasvatushankkeet sekä nuoriin, kansalaisuuteen ja kansalaisyhteiskuntaan liittyvät keskustelut. Maantieteen opetuksen osalta taustana olivat opetussuunnitelman velvoitteet huomioida aktiivinen kansalaisuus yläkoulun maantieteen opetuksessa sekä (pääasiassa brittiläinen) kirjallisuus, jossa maantieteen ja kansalaiskasvatuksen/aktiivisen kansalaisuuden välillä nähdään yhtäläisyyksiä. Tutkielmassa pyrittiin selvittämään, mitä aktiivinen kansalaisuus on yläkoulun maantieteen opetuksessa ja miten maantieteen opettajat suhtautuvat tehtäviinsä nuorten kansalaisten kasvattajina ja yhteiskunnallisina vaikuttajina. Tutkielmaa varten kerättiin teemahaastatteluaineisto kuudelta yläkoulun maantieteen opettajalta. Haastatteluihin pyrittiin löytämään mahdollisimman aktiivisia maantieteen opettajia. Haastatteluaineiston analyysissa käytettiin sisällönanalyysia, ja aineiston avulla pyrittiin kuvaamaan ilmiötä. Haastateltujen opettajien mukaan yläkoulun maantieteen opetuksessa luonnonmaantieteelliset sisällöt painottuvat enemmän kuin kulttuurimaantieteelliset. Aktiivisen kansalaisuuden kannalta keskeisiä sisältöjä, kuten vaikutusmahdollisuuksia oman ympäristön suunnitteluun ja kehittymiseen sekä kotikunnan ja lähiympäristön tutkimista käsitellään opetuksessa vain vähän, jos ollenkaan. Aktiivinen kansalaisuus on yläkoulun maantieteen opetuksessa eniten tiedon jakamista, ajattelun taitojen ja mielipiteen muodostamisen harjoittelua sekä ympäristövastuullisuuteen kansalaisuuteen kasvattamista. Opetuksessa käytetään myös aktiivisen kansalaisuuden kannalta keskeisiä työtapoja, mutta työtapojen käyttö vaihtelee. Haastatellut opettajat eivät koe opetussuunnitelman aihekokonaisuuksia juurikaan omakseen. Opettajat eivät myöskään määrittele kansalaisvaikuttamiseen kasvattamista koulun tärkeimpien tehtävien joukkoon. Osa opettajista kokee kuitenkin olevansa yhteiskunnallinen vaikuttaja opettajana. Opettajien puheessa koulun kansalaiskasvatuksen tavoite, kunnon kansalainen, ei määrity kovin aktiivisena tai poliittisena. Opettajien puhe sisältää kuitenkin monenlaisia näkemyksiä suhteessa nuoriin kansalaisina ja aktiivisuuteen: toisaalta nuoret eivät ole kiinnostuneita yhteiskunnallisista asioista eikä heiltä vaaditakaan sitä, toisaalta maaperä nuorten kasvattamiseen aktiivisiksi kansalaisiksi on hyvä ja aktiivisuus on pieniä asioita lähiympäristössä sekä yhdessä tekemiseen uskomista. Haastattelujen pohjalta todettiin, että lukuun ottamatta joidenkin opettajien ympäristökasvatuksellista otetta, aktiivinen kansalaisuus ei ole täysin tiedostettu tavoite yläkoulun maantieteen opetuksessa.

Factors associated with 2009 pandemic influenza A (H1N1) vaccination acceptance among university students from India during the post-pandemic phase

Background: There was a low adherence to influenza A (H1N1) vaccination program among university students and health care workers during the pandemic influenza in many parts of the world. Vaccination of high risk individuals is one of the recommendations of World Health Organization during the post-pandemic period. It is not documented about the student's knowledge, attitude and willingness to accept H1N1 vaccination during the post-pandemic period. We aimed to analyze the student's knowledge, attitude and willingness to accept H1N1 vaccination during the post-pandemic period in India. Methods: Vaccine against H1N1 was made available to the students of Vellore Institute of Technology, India from September 2010. The data are based on a cross-sectional study conducted during October 2010 to January 2011 using a self-administered questionnaire with a representative sample of the student population (N = 802). Results: Of the 802 respondents, only 102/802 (12.7%) had been vaccinated and 105/802 (13%) planned to do so in the future, while 595/802 (74%) would probably or definitely not get vaccinated in the future. The highest coverage was among the female (65/102, 63.7%) and non-compliance was higher among men in the group (384/595; 64.5%) (p < 0.0001). The representation of students from school of Bio-sciences and Bio-technology among vaccinees is significantly higher than that of other schools. Majority of the study population from the three groups perceived vaccine against H1N1 as the effective preventive measure when compared to other preventive measures. 250/595 (42%) of the responders argued of not being in the risk group. The risk perception was significantly higher among female (p < 0.0001). With in the study group, 453/802 (56.4%) said that they got the information, mostly from media. Conclusions: Our study shows that the vaccination coverage among university students remains very low in the post-pandemic period and doubts about the safety and effectiveness of the vaccine are key elements in their rejection. Our results indicate a need to provide accessible information about the vaccine safety by scientific authorities and fill gaps and confusions in this regard.

A Coalitional Game Framework for Cooperative Secondary Spectrum Access

We consider a framework in which several service providers offer downlink wireless data access service in a certain area. Each provider serves its end-users through opportunistic secondary spectrum access of licensed spectrum, and needs to pay primary license holders of the spectrum usage based and membership based charges for such secondary spectrum access. In these circumstances, if providers pool their resources and allow end-users to be served by any of the cooperating providers, the total user satisfaction as well as the aggregate revenue earned by providers may increase. We use coalitional game theory to investigate such cooperation among providers, and show that the optimal cooperation schemes can be obtained as solutions of convex optimizations. We next show that under usage based charging scheme, if all providers cooperate, there always exists an operating point that maximizes the aggregate revenue of providers, while presenting each provider a share of the revenue such that no subset of providers has an incentive to leave the coalition. Furthermore, such an operating point can be computed in polynomial time. Finally, we show that when the charging scheme involves membership based charges, the above result holds in important special cases.

Is The Burden of Medical Education Affecting Ethics of Medical Treatment?

A substantial number of medical students in India have to bear an enormous financial burden for earning a bachelor's degree in medicine referred to as MBBS (bachelor of medicine and bachelor of surgery). This degree program lasts for four and one-half years followed by one year of internship. A postgraduate degree, such as MD, has to be pursued separately on completion of a MBBS. Every medical college in India is part of a hospital where the medical students get clinical exposure during the course of their study. All or at least a number of medical colleges in a given state are affiliated to a university that mainly plays a role of an overseeing authority. The medical colleges usually have no official interaction with other disciplines of education such as science and engineering, perhaps because of their independent location and absence of emphasis on medical research. However, many of the medical colleges are adept in imparting high-quality and sound training in medical practices including diagnostics and treatment. The medical colleges in India are generally of two types, i.e., government owned and private. Since only a limited number of seats are available across India in the former category of colleges, only a small fraction of aspiring candidates can find admission in these colleges after performing competitively in the relevant entrance tests. A major advantage of studying in these colleges is the nominal tuition fees that have to be paid. On the other hand, a large majority of would-be medical graduates have to seek admission in the privately run medical institutes in which the tuition and other related fees can be mind boggling when compared to their public counterparts. Except for candidates of exceptionally affluent background, the only alternative for fulfilling the dream of becoming a doctor is by financing one's study through hefty bank loans that may take years to pay back. It is often heard from patients that they are asked by doctors to undergo a plethora of diagnostic tests for apparently minor illnesses, which may financially benefit those prescribing the tests. The present paper attempts to throw light on the extent of disparity in cost of a medical education between state-funded and privately managed medical colleges in India; the average salary of a new medical graduate, which is often ridiculously low when compared to what is offered in entry-level engineering and business jobs; and the possible repercussions of this apparently unjust economic situation regarding the exploitation of patients.

Un impuesto singular: el diezmo-señor y la sal en Añana, siglos XVI-XIX

[ES]Cuando a partir de 1564 las salinas de Añana comenzaron a producir para la Corona, sus propietarios se vieron obligados a pagar al rey un tributo anual por el uso de las mueras, admitidas como un ius regalia de la monarquía: el diezmoseñor. Desde entonces, todo el entramado de la fabricación y venta de la sal se organizó en torno a él. En este artículo se analizan algunas de las características de este canon tan singular que se mantuvo en vigor hasta el siglo XX.

Are Bar Associations Anticompetitive? An Empirical Analysis of Recommended Prices for Legal Services in Spain

The European Commission Report on Competition in Professional Services found that recommended prices by professional bodies have a significant negative effect on competition since they may facilitate the coordination of prices between service providers and/or mislead consumers about reasonable price levels. Professional associations argue, first, that a fee schedule may help their members to properly calculate the cost of services avoiding excessive charges and reducing consumers’ searching costs and, second, that recommended prices are very useful for cost appraisal if a litigant is condemned to pay the legal expenses of the opposing party. Thus, recommended fee schedules could be justified to some extent if they represented the cost of providing the services. We test this hypothesis using cross‐section data on a subset of recommended prices by 52 Spanish bar associations and cost data on their territorial jurisdictions. Our empirical results indicate that prices recommended by bar associations are unrelated to the cost of legal services and therefore we conclude that recommended prices have merely an anticompetitive effect.

Consumption and portfolio rules whit stochastic hyperbolic discounting

We extend the classic Merton (1969, 1971) problem that investigates the joint consumption-savings and portfolio-selection problem under capital risk by assuming sophisticated but time-inconsistent agents. We introduce stochastic hyperbolic preferences as in Harris and Laibson (2013) and find closed-form solutions for Merton's optimal consumption and portfolio selection problem in continuous time. We find that the portfolio rule remains identical to the time-consistent solution with power utility and no borrowing constraints. However,the marginal propensity to consume out of wealth is unambiguously greater than the time-consistent, exponential case and,importantly, it is also more responsive to changes in risk. These results suggest that hyperbolic discounting with sophisticated agents offers promise for contributing to explaining important aspects of asset market data.

Harnessing the fishery potential of man-made lakes for the partial commercialisation of Niger River Basin Development Authority, Minna, Nigeria

Niger River Basin Development Authority Minna (NRBDA) is one of the eleven river basins in Nigeria now undergoing transition towards partial commercialisation. In the light of this the need to be self-sustaining through exploration and exploitation of every possible areas along their operation to yield revenue cannot be over-emphasized. Therefore it is most pertinent to consider fisheries activities along their water bodies as one of the major sources of revenue by organising the local fishermen operating along the water into cooperative bodies and made to pay for fishing rights. Strategies to accomplish this objective is highlighted. The need to embark on aquaculture projects by construction of fish ponds at suitable sites along the reservoirs and developing the recreational potentials of their water bodies as sources of revenue is also stressed

Involvement of fishermen children in fishing activities in Lake Chad region

Five fishing villages in Lake Chad Basin region of Borno State (Nigeria) were assessed for the roles of children in fishing activities in the area. The villages surveyed include: Bundaram, Yobe, Daba masara, Dumba and Doro. The results show that the children were largely between 12-18 years of age in the villages. Generally, the younger children (less than 12 years) participate in activities that require no technicality and little physical strength, while the older children (12 years and above) engage in skillful fabrication of gear and fishing activities. Some activities in the surveyed villages were gender specific. Such activities include fish processing (smoking) which is exclusive for female and few male children, who carry out preliminary cleaning of fish before any processing method is applied. 80% of the children in the five fishing villages claimed proper understanding of the techniques and procedure involved in most fishing activities. About 65% of the children sampled showed willingness to become full time fishermen while 22% were uncertain and claimed that they do not know what the future holds for them. 15% of them resolved to migrate to town so that they could live a city life

Essays on economics networks

This thesis belongs to the growing field of economic networks. In particular, we develop three essays in which we study the problem of bargaining, discrete choice representation, and pricing in the context of networked markets. Despite analyzing very different problems, the three essays share the common feature of making use of a network representation to describe the market of interest.

In Chapter 1 we present an analysis of bargaining in networked markets. We make two contributions. First, we characterize market equilibria in a bargaining model, and find that players' equilibrium payoffs coincide with their degree of centrality in the network, as measured by Bonacich's centrality measure. This characterization allows us to map, in a simple way, network structures into market equilibrium outcomes, so that payoffs dispersion in networked markets is driven by players' network positions. Second, we show that the market equilibrium for our model converges to the so called eigenvector centrality measure. We show that the economic condition for reaching convergence is that the players' discount factor goes to one. In particular, we show how the discount factor, the matching technology, and the network structure interact in a very particular way in order to see the eigenvector centrality as the limiting case of our market equilibrium.

We point out that the eigenvector approach is a way of finding the most central or relevant players in terms of the “global” structure of the network, and to pay less attention to patterns that are more “local”. Mathematically, the eigenvector centrality captures the relevance of players in the bargaining process, using the eigenvector associated to the largest eigenvalue of the adjacency matrix of a given network. Thus our result may be viewed as an economic justification of the eigenvector approach in the context of bargaining in networked markets.

As an application, we analyze the special case of seller-buyer networks, showing how our framework may be useful for analyzing price dispersion as a function of sellers and buyers' network positions.

Finally, in Chapter 3 we study the problem of price competition and free entry in networked markets subject to congestion effects. In many environments, such as communication networks in which network flows are allocated, or transportation networks in which traffic is directed through the underlying road architecture, congestion plays an important role. In particular, we consider a network with multiple origins and a common destination node, where each link is owned by a firm that sets prices in order to maximize profits, whereas users want to minimize the total cost they face, which is given by the congestion cost plus the prices set by firms. In this environment, we introduce the notion of Markovian traffic equilibrium to establish the existence and uniqueness of a pure strategy price equilibrium, without assuming that the demand functions are concave nor imposing particular functional forms for the latency functions. We derive explicit conditions to guarantee existence and uniqueness of equilibria. Given this existence and uniqueness result, we apply our framework to study entry decisions and welfare, and establish that in congested markets with free entry, the number of firms exceeds the social optimum.

Poverty alleviation among fishermen within the floodplains of Kaduna River: implication for introducing commercial fish farming at village level in Doko local government area of Niger State, Nigeria

A diagnostic survey was conducted among the fishermen in six selected villages in Doko Local Government Area of Niger State. One hundred and fifty fishermen were randomly selected and interviewed to find out whether or not they had interest in commercial fish farming aimed at improving their livelihood. The dwindling fish catches in the natural flood plain ponds and Ex-bow Lakes continue to have a serious negative effect on the socio-economic well being of the village communities in question. A break on natural regular annual flooding of the plains had resulted into very low natural fish recruitment. Data analysis using simple descriptive statistics revealed that land tenure system, educational status, inadequate infrastructural facilities, religious taboos, existing fish species among others were found to be favourable indices for commercial fish farming. However, serious conflicts among the fishermen concerning the ownership status of these natural fish ponds are found to be major obstacles to commercial fish farming despite that the traditional ownership of the ponds were vested in the lands of individuals and village communities. Extensive fish farming and small-scale fish farming in the ponds and Ex-bow Lake with improved management practices are considered to be profitable venture. Despite the fact that fish seeds supply and extension effort are still inadequate, the fish farmers have indicated willingness to adopt commercial fish farming in the Ex-bow Lakes and flood plains in order to restore abundant fish production thereby providing for their food security and also increasing the daily income

The Freshwater Biological Association at Wray Castle: Recollections of its first director

In 1937 the Development Commission provided an annual grant to the Freshwater Biological Association to pay for a director and secretary. The author moved to the Lake District in the same year, and at that time T.T. Macan was working on invertebrates; K.R. Allen on fish; C.H. Mortimer on chemistry and physics of the aquatic environment, and Marie Rosenberg on phytoplankton. They were backed by George Thompson as laboratory assistant and Rosa Bullen as secretary. The work of the Association continued and expanded throughout the Second World War with some far-reached discoveries made. For example, the recovery of lake sediment cores and the examination of diatom remains, so starting the discipline of archaeo-limnology. Also, a hydrological survey of the Windermere catchment area found significant traces of sulphuric acid in rain gauges. This was more than 30 years before "acid rain" became fashionable.
