NEUTRON ACTIVATION ANALYSIS OF ROMAN AFRICAN RED SLIP WARE KILNS

Roman African Red Slip ware (ARS) sherds from four ARS kiln sites in modern-day Tunisia (El Mahrine, El Ala, Oudna and Pheradi Maius) have been analysed using instrumental neutron activation analysis. Multivariate statistical methods (including cluster analysis and Manhattan City Block distances), with a dilution correction applied to the data, were used to interpret the concentration data. Reference groups for each of the four kiln sites were established. Both El Mahrine and Oudna were described by two dilution-related groups. These kiln groups were all shown to be compositionally distinct from each other and suitable for use in provenance studies.     

PROVENANCE STUDIES OF ROMAN AFRICAN RED SLIP WARE USING NEUTRON ACTIVATION ANALYSIS

African Red Slip ware (ARS) from Carthage and San Sisto Vecchio (Rome) was analysed by neutron activation analysis. The Carthage tableware was linked with Oudna and the type 1 lamps were probably from a northern ARS/lamp factory other than the sources currently investigated. Two samples were central Tunisian, probably manufactured at El Ala. The San Sisto samples divided into three groups and three outliers of undetermined provenance. Group 1 was central Tunisian, probably from El Ala, and was composed entirely of terra sigillata chiara C forms. Group 2 was of unknown origin within northern Tunisia. Group 3 was the largest subset and most of its constituent samples were associated with El Mahrine. Additionally, four samples were linked with Oudna.     

THE FAMILY LIFE CYCLE, LEISURE ACTIVITIES, AND RESIDENTIAL AREA EVALUATION

Life cycle effects on the importance assigned to residential area attributes are examined empirically. The family life cycle is hypothesized to affect residential area aspirations through changes in the frequency and location of leisure activities. The results indicate that the importance of eight residential area attributes varies significantly with life cycle status. The family life cycle also affects participation in leisure activities. However, the initial hypothesis is not supported.
La relation entre le cycle familial et l'importance donnée aux caractéristiques du voisinage est examinée empiriquement. On suggère que le cycle familial affecte les désirs pour des caractéristiques du voisinage en changeant la fréquence et la localité des loisirs. On a trouvé que le cycle familial affecte l'importance des huit caractéristiques aussi bien que les loisirs. Les résultats ne soutiennent pas l'hypothèse de base.

PROPERTY VALUES AND MENTAL HEALTH FACILITIES IN METROPOLITAN TORONTO

Property value data reveal that markets in the vicinity of five mental health facilities in Toronto are essentially identical to those in control areas. The volume of sales activity and the sale price of transactions are generally comparable. The most important influences on sale price are the characteristics of the property itself. Controlling for these characteristics, the presence of a facility has a weak effect on sale price. Distance from facility, facility type, and the number offacilities had no significant effect on price.
La vente de la proprieté fait voir que les marchés à proximité de cinq centres de la santé mentale à Toronto sont essentiellement identiques aux ceux-làà proximité des cas temoins. Le nombre des ventes et le cours du marché sont comparables. Les plus importantes influences sur le cours du marché sont les traites de la propriété elle-même. Si l'on tient en équilibre ces traites, donc on découvre que la présence d'un centre de la santé mentale n'a qu'un effet faible sur le cours du marché. De plus les trois autres éléments (la distance d'un centre, le type du centre, et le nombre des centres) n'ont aucuns effets importants sur le cours du marché.     

POTENTIAL IMPACTS OF GLOBAL SEA-LEVEL RISE ON CANADIAN COASTS

The sea-level rise that may result from global climate change is placed within the context of past and present sea-level changes on Canadian coasts. To assess future impact, a dimensionless index of sensitivity is determined. Coasts with low, moderate, and high sensitivity constitute 67%, 30%, and 3% of the total coastline, respectively. The most sensitive regions are: (1) several parts of the Maritime Provinces; (2) two areas of the British Columbia coast; and (3) a large part of the Beaufort Sea coast. Impacts in four regions - Bay of Fundy, Beaufort Sea, Fraser Delta, and Eastern Shore of Nova Scotia - are discussed in detail. It is argued that the societal response to changes in sea level should favour retreat and accommodation strategies.
Il est possible que les changements climatiques globaux provoqueront une élévation du niveau de la mer. Nous examinons ce scénario dans le contexte des changements passés et présents du niveau de la mer sur les côtes canadiennes. Pour évaluer l'impact de l'élévation prévue un indice non dimensionnel de vulnérabilité est déterminé. Les côtes à la vulnérabilité basse, modérée et élevée constituent, respectivement, 67%, 30%, et 3% de tout le littoral. Les régions les plus vulnérables sont: (1) plusieurs régions dans les provinces maritimes; (2) deux zones sur la côte de la Colombie britannique; et (3) la plupart de la côte de la mer de Beaufort. Nous discutons en détail les impacts dans quatre régions, soit la baie Fundy, la mer Beaufort, la delta du Fraser et la rivage dit 'Eastern Shore' de la Nouvelle-Écosse. Nous estimons que la réponse sociale aux changements du niveau de la mer devrait favoriser des stratégies de retraite et d'accommodement.
