Pouvoir d'attraction d'une artère commerciale : le cas de l'avenue Cartier à Québec

À Québec, les dernières décennies ont été marquées par la dispersion des commerces et des services dans les secteurs de la ville qui bénéficient d’une accessibilité autoroutière accrue. Ces changements ont conduit à une diminution de l’achalandage des rues commerciales situées dans les quartiers centraux. S’attachant au sort de ces anciennes rues commerciales, notre étude s’intéresse aux éléments qui, du point de vue de ses usagers, influencent le pouvoir attractif de l’une d’entre elles : l’avenue Cartier. Au préalable, nous examinons la manière dont les usagers conçoivent mentalement l’extension spatiale du vocable avenue Cartier. Pour ce faire, nous utilisons la technique des groupes nominaux (TGN), un questionnaire et la cartographie participative comme méthodes de collecte de données. Nos résultats montrent que l’avenue Cartier, telle que les répondants se la conçoivent mentalement, dépasse largement ses limites physiques. Par ailleurs, l’offre commerciale et de services, l’offre de restauration et d’alimentation, la dimension sociale, l’atmosphère, la situation géographique, les déplacements des individus, les motivations personnelles sont les composantes qui, en ordre décroissant, influencent la fréquentation de l’avenue Cartier.

Attraction, recruitment and retention of high performing sales professionals case study: Lindström

The goal of this thesis is to gain more in-depth understanding of employer branding and offer suggestions on how this knowledge could be utilized in the case company. More in detail, the purpose of this research is to provide tools for improving Lindström’s organizational attractiveness and boosting the recruitment and retention of the segment of high-performing sales professionals. A strategy for reaching this particular segment has not been previously drawn and HR-managers believe strongly that it would be very beneficial for the company’s development and growth. The topic of this research is very current for Lindström, but also contributes on general level as companies are competing against each other in attracting, recruiting and retention of skilled workforce in the times of labor shortage. The research is conducted with qualitative methods and the data collection includes primary data through interviews as well as secondary data in the form of analysis on previous research, websites, recruitment material and discussions with Lindström’s HR department. This research provides a good basis for broader examination on the topic and presents development suggestions for the identified challenges. Based on the key findings Lindström’s HR department was advised to increase firm’s visibility, broaden recruitment channels, provide more hands-on knowledge about the sales positions and investigate their possibilities of developing sales reward systems.

La cinématographie-attraction à Montréal à la lumière de la législation (1896-1913)

La cinématographie-attraction a longtemps été considérée comme les débuts du cinéma, jusqu’à ce qu’une controverse, en 1978, marque une rupture historiographique et la considère comme un objet d’études à part entière, distinct du cinéma institutionnel. Nous l’analysons ici dans le contexte de Montréal, entre la présentation du Cinématographe Lumière en 1896 et l’entrée en fonction du Bureau de censure des vues animées de la province du Québec en 1913. Plus précisément, nous interrogeons son institutionnalisation à la lumière de la législation ; les représentants du gouvernement canadien donnent un statut juridique aux vues animées en modifiant et en votant des textes légaux. Cette étude définit le contexte cinématographique, historique et géographique. Elle aborde ensuite trois domaines de la cinématographie-attraction qui ne sont pas les mêmes que ceux du cinéma : la fabrication (le financement, le tournage et la modification des œuvres cinématographiques), l’exhibition (les séances de projections payantes d’images animées) et la réception (les jugements portés sur les vues animées). Nous montrons comment la cinématographie-attraction est d’abord contrôlée par de nombreuses personnes (celles qui financent, celles qui tournent les vues animées, les propriétaires de lieux d’amusements, le policier ou le pompier présent au cours des projections), puis par des institutions reconnues et les représentants du gouvernement. En nous appuyant sur la presse montréalaise, les discours officiels, les discours diocésains, les textes légaux, les catalogues publiés par les compagnies de fabrication et sur les vues animées, nous montrons quels sont les enjeux de l’institutionnalisation pour les différents groupes sociaux.

Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 2. Parque Estadual do Alto Ribeira (PETAR), São Paulo State, Brazil

The Parque Estadual do Alto Ribeira (PETAR) with about 250 caves, in an Atlantic forest reserve, is an important ecotourist attraction in the Ribeira Valley, an endemic area of American cutaneous leishmaniasis (ACL). With the purpose of investigating Leishmania vector species bothersome to humans the sandfly fauna was identified and some of its ecological aspects in the Santana nucleus, captures were undertaken monthly with automatic light traps in 11 ecotopes, including caves, forests, a camping site and domiciliary environments, and on black and white Shannon traps, from January/2001 to December/2002. A total of 2,449 sandflies representing 21 species were captured. The highest values of abundance obtained in the captures with automatic light traps were for Psathyromyia pascalei and Psychodopygus ayrozai. A total of 107 specimens representing 13 species were captured on black (12 species) and white (6 species) Shannon traps set simultaneously. Psychodopygus geniculatus females predominated on the black (43.75%), and Psathyromyia lanei and Ps. ayrozai equally (32.4%) on the white. Nyssomyia intermedia and Nyssomyia neivai, both implicated in the transmission of ACL in the Brazilian Southeastern region, were also captured. Ny. intermedia predominated in the open camping area. Low frequencies of phlebotomines were observed in the caves, where Evandromyia edwardsi predominated Lutzomyia longipalpis, the main vector of the American visceral leishmaniasis, was aslo present. This is its most southernly reported occurrence in the Atlantic forest.

Effects of flooding of the River Paraná on the temporal activity of Anopheles (Nyssorhynchus) darlingi Root (Diptera: Culicidae), at the border state of Mato Grosso do Sul and São Paulo, Brazil

INTRODUCTION: Study of the temporal activity of malaria vectors during the implantation of a hydroelectric power station on the River Paraná, intended to generate electrical energy. The river separates the States of São Paulo and Mato Grosso do Sul, in Brazil. The objective was to verify whether alterations occurred in the wealth and diversity indices of Anopheles, following two successive floods, extended to the temporal activity and nycthemeral rhythm followed over a five year period. METHODS: Mosquito capture was performed monthly using the Human Attraction Technique and Shannon Traps. The first, executed for 24h, provided the nycthemeral rhythm and the second, lasting 15h, permitted the tracking of Anopheles during the two floods. RESULTS: The bimodal pattern of Anopheles darlingi defined before these floods was modified throughout the environment interventions. The same effect had repercussions on the populations of An albitarsis s.l., An triannulatus and An galvaoi. Activity prior to twilight was less affected by the environment alterations. CONCLUSIONS: The dam construction provoked changes in Anopheles temporal activity patterns, permitting classification of the area as an ecologically steady and unstable situation. Differences observed in Anopheles behavior due to the capture methods revealed the influence of solo and multiple attractiveness inside the populations studied.

Ecologia de Anopheles (Nyssorhynchus) darlingi Root em área de implantação de empreendimento hidrelétrico, na divisa dos Estados do Mato Grosso do Sul e São Paulo

INTRODUÇÃO: Hidrelétricas alteram o fluxo das águas e provocam impactos sobre a composição de mosquitos, justificando-se essa pesquisa. O objetivo da pesquisa foi estudar anofelinos de área sob a influência de um novo lago e avaliar a vulnerabilidade relativa à malária. MÉTODOS: Foram feitas coletas de Anopheles nas margens da Represa Porto Primavera, durante as fases do alagamento até sua cota máxima. Utilizaram-se as técnicas: atrativa humana, de armadilha de Shannon e concha entomológica. Os indicadores Riqueza e Diversidade foram utilizados para medir o impacto. A análise das distribuições temporais foi realizada pelo teste Mann-Whitney, considerando localidade, cota e método de captura como variáveis independentes (α=0,05). RESULTADOS: A densidade de Anopheles darlingi oscilou entre as localidades A, B e C, sendo que os maiores picos foram para B e C. Com a estabilidade do lago, no último nível, evidenciou-se a tendência de redução da densidade de Anopheles darlingi. CONCLUSÕES: Sugere-se que o risco de autoctonia de malária nas proximidades do lago permanece inalterado, ficando o alerta para esporádicas infecções humanas.

Phylogenetic placement of the enigmatic parasite, Polypodium hydriforme, within the Phylum Cnidaria

Background: Polypodium hydriforme is a parasite with an unusual life cycle and peculiar morphology, both of which have made its systematic position uncertain. Polypodium has traditionally been considered a cnidarian because it possesses nematocysts, the stinging structures characteristic of this phylum. However, recent molecular phylogenetic studies using 18S rDNA sequence data have challenged this interpretation, and have shown that Polypodium is a close relative to myxozoans and together they share a closer affinity to bilaterians than cnidarians. Due to the variable rates of 18S rDNA sequences, these results have been suggested to be an artifact of long-branch attraction ( LBA). A recent study, using multiple protein coding markers, shows that the myxozoan Buddenbrockia, is nested within cnidarians. Polypodium was not included in this study. To further investigate the phylogenetic placement of Polypodium, we have performed phylogenetic analyses of metazoans with 18S and partial 28S rDNA sequences in a large dataset that includes Polypodium and a comprehensive sampling of cnidarian taxa. Results: Analyses of a combined dataset of 18S and partial 28S sequences, and partial 28S alone, support the placement of Polypodium within Cnidaria. Removal of the long-branched myxozoans from the 18S dataset also results in Polypodium being nested within Cnidaria. These results suggest that previous reports showing that Polypodium and Myxozoa form a sister group to Bilateria were an artifact of long-branch attraction. Conclusion: By including 28S rDNA sequences and a comprehensive sampling of cnidarian taxa, we demonstrate that previously conflicting hypotheses concerning the phylogenetic placement of Polypodium can be reconciled. Specifically, the data presented provide evidence that Polypodium is indeed a cnidarian and is either the sister taxon to Hydrozoa, or part of the hydrozoan clade, Leptothecata. The former hypothesis is consistent with the traditional view that Polypodium should be placed in its own cnidarian class, Polypodiozoa.

Polyelectrolyte-protein complexation driven by charge regulation

The interplay between the biocolloidal characteristics (especially size and charge), pH, salt concentration and the thermal energy results in a unique collection of mesoscopic forces of importance to the molecular organization and function in biological systems. By means of Monte Carlo simulations and semi-quantitative analysis in terms of perturbation theory, we describe a general electrostatic mechanism that gives attraction at low electrolyte concentrations. This charge regulation mechanism due to titrating amino acid residues is discussed in a purely electrostatic framework. The complexation data reported here for interaction between a polyelectrolyte chain and the proteins albumin, goat and bovine alpha-lactalbumin, beta-lactoglobulin, insulin, k-casein, lysozyme and pectin methylesterase illustrate the importance of the charge regulation mechanism. Special attention is given to pH congruent to pI where ion-dipole and charge regulation interactions could overcome the repulsive ion-ion interaction. By means of protein mutations, we confirm the importance of the charge regulation mechanism, and quantify when the complexation is dominated either by charge regulation or by the ion-dipole term.

Artificial Lighting as a Vector Attractant and Cause of Disease Diffusion

BACKGROUND: Traditionally, epidemiologists have considered electrification to be a positive factor. In fact, electrification and plumbing are typical initiatives that represent the integration of an isolated population into modern society, ensuring the control of pathogens and promoting public health. Nonetheless, electrification is always accompanied by night lighting that attracts insect vectors and changes people's behavior. Although this may lead to new modes of infection and increased transmission of insect-borne diseases, epidemiologists rarely consider the role of night lighting in their surveys. OBJECTIVE: We reviewed the epidemiological evidence concerning the role of lighting in the spread of vector-borne diseases to encourage other researchers to consider it in future studies. DISCUSSION: We present three infectious vector-borne diseases-Chagas, leishmaniasis, and malaria-and discuss evidence that suggests that the use of artificial lighting results in behavioral changes among human populations and changes in the prevalence of vector species and in the modes of transmission. CONCLUSION: Despite a surprising lack of studies, existing evidence supports our hypothesis that artificial lighting leads to a higher risk of infection from vector-borne diseases. We believe that this is related not only to the simple attraction of traditional vectors to light sources but also to changes in the behavior of both humans and insects that result in new modes of disease transmission. Considering the ongoing expansion of night lighting in developing countries, additional research on this subject is urgently needed.

Multistability and Self-Similarity in the Parameter-Space of a Vibro-Impact System

The dynamics of a dissipative vibro-impact system called impact-pair is investigated. This system is similar to Fermi-Ulam accelerator model and consists of an oscillating one-dimensional box containing a point mass moving freely between successive inelastic collisions with the rigid walls of the box. In our numerical simulations, we observed multistable regimes, for which the corresponding basins of attraction present a quite complicated structure with smooth boundary. In addition, we characterize the system in a two-dimensional parameter space by using the largest Lyapunov exponents, identifying self-similar periodic sets.
