Strategies for economic development in the Commonwealth Caribbean: a comparative study of the foreign economic policy strategies adopted by the Manley government in Jamaica and the Williams government in Trinidad and Tobago

This thesis compares the foreign economic poUcy dimension of the development strategies adopted by the governments of two Commonwealth caribbean countries: The Hardey government In Jamaica, and the· Williams government in Trlnidad and T ooago, The foreign economic policIes adopted by these governments appeared, on the surface~ to be markedly dissimilar. The Jamakan strategv on the one hand, emphasised self-reliance and national autonomy; and featured the espousal of radical oonaHgnment together with attempts to re-deftne the terms of the Islands externaa economIc relaUoos. The Trinidadian strategy 00 the other hand, featured Uberal externaUy-oriented growth poUctes, and close relatjoos with Western governments and financial institutions. Th1s study attempts to identify the explanatory factors that account for the apparent dlssimUarUy 1n the foreign economic policies of these two govemnents. The study is based on a comparison of how the structural bases of an underdeveloped ecooomYg and the foreign penetration and vulnerabUUy to external pressures asSOCiated wUh dependence, shape and influence foreign economic poUcy strategy. The framework views fore1gn ecooom1c strategy as an adaptive response on the part of the decision makers of a state to the coostralnts and opportunities provided by a particular situation. The · situat i 00' in this case being the events, conditions, structures and processes, associated wUh dependente and underdevelopment. The results indicate that the similarities and dissimHarities in the foreign economic policies of the governments of Jamaica and Trinidad were a reflecUon of the simHarities and dissimilarities in their respective situations. The conclusion derived suggests that If the foreign pol1cy field as an arena of choice, Is indeed one of opportunities and constraints for each and every state, then poHcy makers of smaU, weak, hlghW penetrated and vulnerable states enter thlS arena with constraints outweighing opportunities. This places effective limits 00 their decisional latitude and the range of policy options avaUable. Policy makers thus have to decide critical issues with few estabUshed precedents, in the face of domestic social and political cleavages, as wen as serious foreign pressures. This is a reflection not only of the trappings of dependence, but also of the Umned capabilities arising from the sman size of the state, and the Impact of the resource-gap In an underdeveloped economy. The Trinidadian strategy 1s UlustraUve of a development strategy made viable through a combination of a fortuitous circumstance, a confluence of the interests of influential groups» and accurate perception on the part of poUcy makers. These factors enabled policy makers to minimise some of the constraints of dependence. The faUure of Manlets strategy on the other hand, 15 iHustraUve of the problems involved tn the adoption of poUcles that work against the interest of internal and external political and economic forces. It is also tUustraUve of the consequences of the faUure 00 the part of policy makers to clarify goals, and to reconcile the values of rapid economic growth with increased self-reliance and national autonomy. These values tend to be mutuany Incompatible given the existing patterns of relations in the jnternational economy.

Les déterminants de l'épuisement professionnel et des troubles musculosquelettiques et leur cooccurrence chez les policiers

Ce mémoire est rédigé dans le cadre d’une recherche multidisciplinaire visant à développer de meilleurs outils d’intervention et politiques en santé mentale au travail. L’objectif principal de cette étude était de cibler les déterminants de l’épuisement professionnel et des troubles musculosquelettiques et leur cooccurrence chez une population policière. Un échantillon de 410 policiers du Service de Police de Montréal (SPVM) a été sondé à l’aide d’un questionnaire basé sur des outils standardisés en santé mentale au travail. Les conditions organisationnelles, variables indépendantes de cette étude, ont été identifiées à partir de modèles théoriques validés. L’analyse segmentée de chacun des grands concepts (latitude décisionnelle, soutien social au travail, demandes, justice distributive et sur engagement) révèle que l’effet des conditions organisationnelles ne se manifeste pas également sur chacune des trois dimensions de l’épuisement professionnel (l’épuisement émotionnel, le cynisme et l’efficacité professionnelle). De plus, on observe que les trois formes de récompenses de justice distributive tirées du modèle « Déséquilibre-Efforts-Récompenses » (Siegrist, 1996) ne sont pas distribuées également selon les dimensions de l’épuisement professionnel. Selon nos données, la justice distributive d’estime de soi et le sur engagement s’avèrent significatifs dans tous les cas en regard des dimensions de l’épuisement professionnel et de son indice global. Finalement, nos résultats révèlent que la justice distributive d’estime de soi a un lien significatif sur la cooccurrence de l’épuisement professionnel et des troubles musculosquelettiques. Par contre, on note que des outils de recherche plus spécifiques permettraient une analyse approfondie de l’effet des conditions organisationnelles sur les troubles musculosquelettiques et sur l’effet de cooccurrence entre les deux problèmes à l’étude.

L'influence de la culture organisationnelle sur l'épuisement professionnel ; étude comparative entre cols blancs et policiers d'un service de police urbain.

Ce mémoire élaboré dans le cadre d'une étude plus vaste sur la santé mentale au travail étudie l'effet de la culture organisationnelle ainsi que certains facteurs du travail comme la supervision abusive, la latitude décisionnelle, l'utilisation des compétences, l'autorité décisionnelle, les demandes psychologiques, le soutien social ainsi que l'horaire de travail sur l'épuisement professionnel et ses trois dimensions. Ces facteurs, à l'exception de la culture organisationnelle ont fait l'objet d'études approfondies dans le passé. Ce mémoire se base sur un modèle connu et régulièrement utilisé mesurant l'effet de ces facteurs du travail sur la santé mentale. Ce modèle est communément appelé le modèle demandes-contrôle de Karasek. L'échantillon à l'étude est constitué de 384 policiers et travailleurs cols blancs travaillant pour le service de police de la Ville de Montréal. La récolte des données à été effectuée en 2008 et 2009. Ce mémoire confirme en partie les résultats fréquemment observés dans les études sur le sujet. La supervision abusive, les demandes psychologiques et certains types de culture augmentent le niveau d'épuisement professionnel. D'autres variables comme la latitude décisionnelle et certains autres types de culture organisationnelle réduisent le niveau d'épuisement professionnel.

The qWR star HD 45166 - II. Fundamental stellar parameters and evidence of a latitude-dependent wind

Context. The enigmatic object HD 45166 is a qWR star in a binary system with an orbital period of 1.596 day, and presents a rich emission-line spectrum in addition to absorption lines from the companion star (B7 V). As the system inclination is very small (i = 0.77 degrees +/- 0.09 degrees), HD 45166 is an ideal laboratory for wind-structure studies. Aims. The goal of the present paper is to determine the fundamental stellar and wind parameters of the qWR star. Methods. A radiative transfer model for the wind and photosphere of the qWR star was calculated using the non-LTE code CMFGEN. The wind asymmetry was also analyzed using a recently-developed version of CMFGEN to compute the emerging spectrum in two-dimensional geometry. The temporal-variance spectrum (TVS) was calculated to study the line-profile variations. Results. Abundances and stellar and wind parameters of the qWR star were obtained. The qWR star has an effective temperature of T(eff) = 50 000 +/- 2000 K, a luminosity of log(L/L(circle dot)) = 3.75 +/- 0.08, and a corresponding photospheric radius of R(phot) = 1.00 R(circle dot). The star is helium-rich (N(H)/N(He) = 2.0), while the CNO abundances are anomalous when compared either to solar values, to planetary nebulae, or to WR stars. The mass-loss rate is. M = 2.2 x 10(-7) M(circle dot) yr(-1), and the wind terminal velocity is v(infinity) = 425 km s(-1). The comparison between the observed line profiles and models computed under different latitude-dependent wind densities strongly suggests the presence of an oblate wind density enhancement, with a density contrast of at least 8: 1 from equator to pole. If a high velocity polar wind is present (similar to 1200 km s(-1)), the minimum density contrast is reduced to 4:1. Conclusions. The wind parameters determined are unusual when compared to O-type stars or to typical WR stars. While for WR stars v(infinity)/v(esc) > 1.5, in the case of HD 45166 it is much smaller (v(infinity)/v(esc) = 0.32). In addition, the efficiency of momentum transfer is eta = 0.74, which is at least 4 times smaller than in a typical WR. We find evidence for the presence of a wind compression zone, since the equatorial wind density is significantly higher than the polar wind. The TVS supports the presence of such a latitude-dependent wind and a variable absorption/scattering gas near the equator.

Relationships among climate, latitude and migration: Australian butterflies are not temperate-zone birds

We examined the distribution of butterflies over the mostly arid and semi-arid continent of Australia and analyzed the proportion of migrant species and species diversity with respect to an array of climatic and geographic variables. On a continent-wide scale, latitude explained virtually no variance in either proportion of migrants (r(2) = 0.01) or species diversity (r(2) = 0.03) in Australian butterflies. These results are in marked contrast to those for temperate-zone birds from three continents where latitude explained between 82 and 98% of the variance in frequency of migrants and also accounted for much of the variance in bird species diversity. In eastern Australia where rainfall regimes are similar to those in temperate Europe and North and South America, latitude explains 78% of the variance in frequency of butterfly migrants. In both eastern and central Australia, latitude also accounts for relatively high proportions of the variance in species diversity. Rainfall patterns and especially soil moisture are negatively associated with migration frequency in Australian butterfly faunas, both alone and in combination with other climate variables. Where moisture levels are relatively high, as in eastern Australia, measures of temperature are associated with migration frequency, a result consistent with findings for temperate-zone birds, suggesting latitude is a surrogate for temperature. The ultimate causes of migration in temperate-zone birds and Australian butterflies are the uneven temporal, and in Australia also spatial, distribution of resources. Uneven distribution is brought about primarily by temperature in temperate regions and by erratic rainfall over much of arid Australia. As a key determinant of productivity, especially in the tropics and subtropics, aridity is likely to be an important determinant of the global distributions of migrants.

ERP 'old/new' effects: memory strength and decisional factor(s)

Event-related potentials (ERPs) were recorded while subjects made old/new recognition judgments on new unstudied words and old words which had been presented at study either once ('weak') or three times ('strong'). The probability of an 'old' response was significantly higher for strong than weak words and significantly higher for weak than new words. Comparisons were made initially between ERPs to new, weak and strong words, and subsequently between ERPs associated with six strength-by-response conditions. The N400 component was found to be modulated by memory trace strength in a graded manner. Its amplitude was most negative in new word ERPs and most positive in strong word ERPs. This 'N400 strength effect' was largest at the left parietal electrode (in ear-referenced ERPs). The amplitude of the late positive complex (LPC) effect was sensitive to decision accuracy (and perhaps confidence). Its amplitude was larger in ERPs evoked by words attracting correct versus incorrect recognition decisions. The LPC effect had a left > right, centro-parietal scalp topography (in ear-referenced ERPs). Hence, whereas, the majority of previous ERP studies of episodic recognition have interpreted results from the perspective of dual-process models, we provide alternative interpretations of N400 and LPC old/new effects in terms of memory strength and decisional factor(s).

Millennial and orbital variations of El Nino/Southern Oscillation and high-latitude climate in the last glacial period

The El Nino/Southern Oscillation (ENSO) phenomenon is believed to have operated continuously over the last glacial interglacial cycle(1). ENSO variability has been suggested to be linked to millennial-scale oscillations in North Atlantic climate during that time(2,3), but the proposals disagree on whether increased frequency of El Nino events, the warm phase of ENSO, was linked to North Atlantic warm or cold periods. Here we present a high-resolution record of surface moisture, based on the degree of peat humification and the ratio of sedges to grass, from northern Queensland, Australia, covering the past 45,000 yr. We observe millennial-scale dry periods, indicating periods of frequent El Nino events ( summer precipitation declines in El Nino years in northeastern Australia). We find that these dry periods are correlated to the Dansgaard - Oeschger events - millennial-scale warm events in the North Atlantic climate record - although no direct atmospheric connection from the North Atlantic to our site can be invoked. Additionally, we find climatic cycles at a semiprecessional timescale (, 11,900 yr). We suggest that climate variations in the tropical Pacific Ocean on millennial as well as orbital timescales, which determined precipitation in northeastern Australia, also exerted an influence on North Atlantic climate through atmospheric and oceanic teleconnections.

A low-latitude bloom of the surf-zone diatom, Anaulus australis (Centrales, Bacillariophyta) on the coast of Southern Queensland (Australia)

A novel bloom of the surf diatom Anaulus australis Drebes et Schultz was observed in subtropical waters off Surfers' Paradise, Queensland, Australia (27 degrees 55'S; 153 degrees 23'E) in early May 2000. This is the lowest latitude in which an Anaulus australis surf diatom bloom has been reported. Nitrogen stable isotope analysis of surf diatoms may indicate anthropogenic nutrient inputs in this environment.

Influence of altitude, latitude and season of collection (Bergmann's Rule) on the dimensions of Lutzomyia intermedia (Lutz & Neiva, 1912) (diptera, psychodidae, phlebotominae)

The influence of altitude and latitude on some structure sizes of Lutzomyia intermedia was noted; several structures of insects collected in higher localities were greater, according to Bergmann's rule. This influence was more remarkable in two localities of the State of Espírito Santo, probably due to greater differences in altitude. Comparing insects from different latitudes, more differences were noted in comparisons of insects from low altitude localities than in those of material from higher altitudes. The small number of differences between insects collected in July and in December does not indicate a defined influence of season and temperature on the size of adults. The possible epidemiological implications of these variations are discussed.
