Abstract: Since the early 1960s, the only pan‐Canadian association of municipalities has shown two decades of decline followed by two decades of growth. This paper analyses this decline and subsequent growth in the context of the changing position of municipalities with Canada, particularly those in Quebec. Examination of the association's recent history provides useful insights into how Canada's municipalities cope with Canadian federalism. It provides lessons as to how best to prosper as a pan‐Canadian organization concerned with what are mainly matters of provincial interest. The paper's theoretical contribution includes reference to the nature and roles of interest groups in Canadian federalism and to the application of structural contingency theory. Sommaire: Depuis le début des annees 1960, l'unique association pancanadienne de municipalités a connu deux décennies de déclin suivies par deux décennies de crois‐sance. Le présent article analyse ce déclin et cette croissance dans le contexte de la position changeante des municipalites à l'égard du Canada, en particulier celles du Québec. L'examen de la récente histoire dee l'association suscite des réflexions utiles sur la maniére dont les municipalités au Canada font face au fédéralisme canadien. II explique comment un organisme pancanadien principalement préoccupé par des questions d'intérséCt provincial pour prospérer le mieux possible. La contribution théorique de l'article fait référence à la nature et aux rôles des groupes d'intéráCts dans le fédéralisme canadien et à l'application de la théorie de contingence structurale.  相似文献

This paper questions the appropriateness of some of the 'help' that has already been given in mental health in 'developing' countries, particularly Africa, and examines some of the complex ideological issues underlying different cultural understandings of the aetiology and treatment of mental illness. Some personal experiences, illustrating examples of the imposition of culturally inappropriate ideology in the teaching of psychiatry, are described. In conclusion, some principles of good practice are suggested which could form the basis of a synthesis between cultures, and maximise the possibility of Western aid in the field of mental distress being more culturally appropriate.  相似文献

Robust voting     
Bassett  Gilbert W.  Persky  Joseph 《Public Choice》1999,99(3-4):299-310
The formal equivalence between social choice and statistical estimation means that criteria used to evaluate estimators can be interpreted as features of voting rules. The robustness of an estimator means, in the context of social choice, insensitivity to departures from majority opinion. In this paper we consider the implications of substituting the median, a robust, high breakdown estimator, for Borda's mean. The robustness of the median makes the ranking method insensitive to outliers and reflect majority opinion. Among all methods that satisfy a majority condition, median ranks is the unique one that is monotonic. It is an attractive voting method when the goal is the collective assessment of the merits of alternatives.  相似文献

Tabernanthe iboga belongs to the Apocynaceae family. In this study, we report the case of a 37-year-old black male working as a security agent in Paris and found dead naked on the beach in Gabon after consumption of iboga. Autopsy revealed a drowning fatality and a myocardial abnormality (myocardial bridging). Samples of blood, urine, bile, gastric content, liver, lungs, vitreous, spleen and hair were taken. Biological fluids were liquid-liquid extracted with saturated NH4Cl pH 9.5 and methylene chloride/isopropanol (95/5, v/v) in presence of clonazepam-d(4), used as internal standard. After decontamination with dichloromethane, hair was cut into small pieces then sonicated for 2h in saturated NH4Cl pH 9.5 before extraction by methylene chloride/isopropanol (95/5, v/v). After evaporation the residues were reconstituted in methanol/ACN/formate buffer pH 3, from which 10 microL were injected into an ODB Uptisphere C(18) column (150 mm x 2.1mm, 5 microm) and eluted with a gradient of acetonitrile and formate buffer delivered at a flow rate of 200 microL/min. A Quantum Ultra triple-quadrupole mass spectrometer was used for analyses. Ionization was achieved using electrospray in the positive ionization mode (ESI). For each compound, detection was related to three daughter ions (ibogaine: m/z 311.4-->122.1, 174.1 and 188.1; noribogaine: m/z 297.4-->122.1, 159.1 and 160.1; clonazepam-d(4): m/z 319.9-->218.1, 245.1 and 274.1). Ibogaine and noribogaine were detected in all autopsy samples. Hair segmentation was not possible as hair was very short and frizzy. Concentrations of 1.2 and 2.5 ng/mg, respectively were detected. Neither other licit or illicit drugs nor alcohol were found. The presence of ibogaine and noribogaine in all autopsy samples was consistent with the recent absorption of Tabernanthe iboga, which was assumed to be responsible of the drowning fatality. The history of exposure, regarding hair analysis, is discussed. LC-MS/MS appears to be the best method for analyzing complex and poorly volatile alkaloids in autopsy samples and particularly in hair, due to the presence of a nitrogen ring and the relatively low concentrations to be measured.  相似文献

Abstract: Despite having significant internal injuries, victims of motor vehicle accidents may have surprisingly few external manifestations of trauma. The water test describes a technique whereby water placed in an upwardly facing ear results in drainage from the nose and opposite ear, thus demonstrating transcranial passage of water. This sign can be demonstrated in cases of blunt cranial trauma where there is a “hinge” fracture involving the petrous temporal bones bilaterally associated with a ring fracture extending around the foramen magnum posteriorly. Such a fracture results in separation of the posterior and middle cranial fossae providing a track for water to traverse. The water test provides a quick and noninvasive method for demonstrating the presence of a particular type of skull fracture.  相似文献

Successful approaches to race determination of unidentified human remains have been developed by anatomists and physical anthropologists, but few quantitative methods are available for distinguishing American Indian crania from those of whites. The leading method in use today is particularly ineffective in its placement of American Indian skulls from the western regions of the United States. Recent development and testing of a new metric method suggests a much more effective technique. The method involves six breadth and projection measurements of the midfacial skeleton, the calculation of three indices, and a simple direct reading of results. The method has the additional advantage of use in the autopsy room with minimal dissection of soft tissue required. Based upon a less extensive test of East Asian and Arctic Mongoloid crania, the method appears to be even more effective in separating them from the sharp featured whites. Larger samples of American blacks and Polynesians are presently under study and these also appear to separate quite readily from whites using the same or similar sectioning values.  相似文献

This study used conflict resolution role play vignettes and self-report surveys of 450 New York City 6th graders to examine associations between adolescents’ conflict resolution efficacy and social skills. Vignettes covered 3 social contexts, conflict with a peer (disagreement over activities), with a parent (raise in allowance), and with a teacher (low grade on report). Effective and ineffective strategies for resolving these conflicts were coded from the videotaped interactions. Adolescents were more often effective in resolving conflict with peers than with parents (χ2(1) = 7.10, p < .01). Strong communication skills cut across interpersonal context as associated with effective resolution. Assertiveness and absence of aggression were associated with effective conflict resolution in vignettes with peers. Assertiveness was also associated with effective conflict resolution in vignettes with parents, however nervousness was unexpectedly found to facilitate conflict resolution in vignettes with parents. Only skills observed within a particular context were associated with effective resolution in that context; self-report skills and cross-context observed skills were not associated with efficacy. Implications for implementation and evaluation of social skills curricula and conflict resolution process are discussed.An earlier version of this paper was presented at the meetings of the Society for Research on Adolescence, New Orleans, LA, April 2002Received Ph.D. in Developmental Psychology from Teachers College, Columbia University in 2004.
