In 2008, the Institut national de santé publique du Québec (INSPQ) undertook a research programme on lotteries. The preliminary qualitative exploratory component enabled us to observe the diversity and ubiquity of lottery advertising to which the vast majority of the population is exposed, including minors and non-players. The aim of a second component was to better comprehend the relationships between exposure to lottery marketing, lottery purchasing habits, attitudes towards gambling, and socio-economic vulnerability indicators. The study's data was collected by a polling firm from a representative sample of adults in the Québec population (n = 2001). Our survey revealed significant links between exposure, gambling behaviour and certain socio-economic indicators: for example, individuals with lower levels of education more often play the lotteries and spend the most on them. In addition, a greater number of people who are less educated and from a low-income household considered that lottery advertising was very or excessively present in their daily lives and that the amount of advertising has increased in recent years. From the perspective of creating healthy environments and protecting vulnerable populations, legislative measures to control the quantity, location and contents of gambling marketing would be promising preventive measures.  相似文献

In censuses and surveys in most African countries it has become the practice to estimate informants' age by the method of the historical calendar. This involves an attempt to relate a remembered historical event, occurring during the subject's childhood, with his age at the time.

This paper attempts a first evaluation of the method with particular reference to the 1961–63 multi-round survey in rural Morocco. It is shown that in practice the method is highly complex and easily misunderstood by interviewers and respondents. An attempt to lay down a precise procedure by means of a very detailed questionnaire appeared to yield at best only marginally more accurate results than the simpler procedure used in an earlier round. The more complex questionnaire did, however, introduce new patterns of misuse by the interviewer. There was evidence that the historical calendar gave somewhat better data than eye estimates, but results were highly defective for both methods.

It is clear that the method is far from perfect. Interviewer training and supervision remain the key to accurate age determination. If the potential benefits of the complex historical calendar method are to be realized, training and supervision need to be even more thorough than where simpler methods are used.  相似文献

ABSTRACT

This research highlights the views of front-line workers in the social assistance system in Turkey about the strategies of poverty reduction and the effectiveness of the assistance given by Social Assistance and Solidarity Foundations (SASFs) to the poor. The data were gathered from 33 employees from the 8 SASF offices in Ankara, Turkey. The results show that the majority of the participants agree with governmental efforts to create employment opportunities as the most important method. Although the participants felt the services they provided were effective at the individual and family level, they thought such services were extremely insufficient in terms of poverty reduction on a macro scale. The findings were discussed within the framework of the changing nature of poverty and the recent agenda on poverty reduction in Turkey. Future research based upon larger samples from different parties in the field of social assistance is needed to fully determine the positions taken by the agents.  相似文献

This paper studies the problem of testing if an input (Γ,°), where Γ is a finite set of unknown size and ° is a binary operation over Γ given as an oracle, is close to a specified class of groups. Friedl et al. (Proc. of STOC, 2005) have constructed an efficient tester using poly(log|Γ|) queries for the class of abelian groups. We focus in this paper on subclasses of abelian groups, and show that these problems are much harder: Ω(|Γ|1/6) queries are necessary to test if the input is close to a cyclic group, and Ω(|Γ| c ) queries for some constant c are necessary to test more generally if the input is close to an abelian group generated by k elements, for any fixed integer k≥1. We also show that knowledge of the size of the ground set Γ helps only for k=1, in which case we construct an efficient tester using poly(log|Γ|) queries; for any other value k≥2 the query complexity remains Ω(|Γ| c ). All our upper and lower bounds hold for both the edit distance and the Hamming distance. These are, to the best of our knowledge, the first nontrivial lower bounds for such group-theoretic problems in the property testing model and, in particular, they imply the first exponential separations between the classical and quantum query complexities of testing closeness to classes of groups.  相似文献

A social choice correspondence called the Essential set is studied with the help of an axiom called Cloning Consistency. Cloning consistency is the requirement that the formal choice rule be insensitive to the replication of alternatives. The Essential set is the support of the optimal mixed strategies in a symmetric two-party electoral competition game. Received: 24 March 1998/Accepted: 3 March 1999  相似文献

We qualify a social choice correspondence as resolute when its set valued outcomes are interpreted as mutually compatible alternatives which are altogether chosen. We refer to such sets as “committees” and analyze the manipulability of resolute social choice correspondences which pick fixed size committees. When the domain of preferences over committees is unrestricted, the Gibbard–Satterthwaite theorem—naturally—applies. We show that in case we wish to “reasonably” relate preferences over committees to preferences over committee members, there is no domain restriction which allows escaping Gibbard–Satterthwaite type of impossibilities. We also consider a more general model where the range of the social choice rule is determined by imposing a lower and an upper bound on the cardinalities of the committees. The results are again of the Gibbard–Satterthwaite taste, though under more restrictive extension axioms.  相似文献

In 1945, at the end of the Second World War, Albania had the highest fertility in Europe with an average of more than six live births per woman. However when Albania emerged from behind the 'olive curtain' in 1990, fertility had fallen to three children per woman, despite a pro-natalist environment and in the virtual absence of contraception and abortion. Nevertheless, after five decades, Albania's position at the top of the European fertility league remains unchanged. This paper documents the fertility transition in Albania during the period 1950-90 and places the demographic results in the context of recent socioeconomic and cultural change.  相似文献

This study is an attempt to empirically detect the public opinion concerning majoritarian approval axiom. A social choice rule respects majoritarian approval iff it chooses only those alternatives which are regarded by a majority of “voters” to be among the “better half” of the candidates available. We focus on three social choice rules, the Majoritarian Compromise, Borda’s Rule and Condorcet’s Method, among which the Majoritarian Compromise is the only social choice rule always respecting majoritarian approval. We confronted each of our 288 subjects with four hypothetical preference profiles of a hypothetical electorate over some abstract set of four alternatives. At each hypothetical preference profile, two representing the preferences of five and two other of seven voters, the subject was asked to indicate, from an impartial viewpoint, which of the four alternatives should be chosen whose preference profile was presented, which if that is unavailable, then which if both of the above are unavailable, and finally which alternative should be avoided especially. In each of these profiles there is a Majoritarian Compromise-winner, a Borda-winner and a Condorcet-winner, and the Majoritarian Compromise-winner is always distinct from both the Borda-winner and the Condorcet-winner, while the Borda- and Condorcet-winners sometimes coincide. If the Borda- and Condorcet-winners coincide then there are two dummy candidates, otherwise only one, and dummies coincide with neither of the Majoritarian Compromise-, Borda- or Condorcet-winner. We presented our subjects with various types of hypothetical preference profiles, some where Borda respecting majoritarian approval, some where it failed to do so, then again for Condorcet, some profiles it respected majoritarian approval and some where it did not. The main thing we wanted to see was whether subjects’ support for Borda and Condorcet was higher when this social choice rule respected majoritarian approval than it did not. Our unambiguous overall empirical finding is that our subjects’ support for Borda and Condorcet was significantly stronger as they respect majoritarian approval.  相似文献
