The poor safety record of the construction industry raises concerns about the extent to which it is able to integrate workers disabled as a result of a workplace injury back to the workplace. A review of the literature indicates there is little empirical evidence about the status of disability management (DM) in the Canadian construction industry, specifically with respect to injured construction workers returning to the workplace with a disability. To address this limitation, a web-based survey was administered to a sample of Manitoban construction organizations to enquire about workers disabled as a result of a workplace injury in the industry, practices in place to accommodate them, and barriers to their employment. The analysis of the responses of 88 organizations showed that the majority of responding organizations employed few disabled workers. Disabilities due to musculoskeletal injuries were the most common, followed by physical mobility and hearing impairments. Respondents saw retaining valued and experienced employees and maintaining employee morale as the main reasons for implementing a DM program. They also found the lack of suitable modified or alternate work to be the most important barrier to DM; however, they identified the provision of such work as the most common practice implemented by them, raising questions about this work's suitability to disabled workers. Key words: construction, disability management, disabled workers, return to work programs. Le bilan mediocre du secteur de la construction en matiere de securite souleve des questions quant a la capacite de ce dernier a reemployer des travailleurs devenus invalides a la suite d'un accident du travail. En examinant la litterature specialisee, on constate qu'il existe tres peu de donnees empiriques sur l'etat de la gestion de l'invalidite (GI) dans le secteur canadien de la construction, en particulier en ce qui concerne les employes de ce secteur qui retournent au travail tout en etant invalides. Pour combler cette lacune, on a realise un sondage en ligne aupres d'un echantillon d'organismes du secteur manitobain de la construction, afin de collecter des donnees sur les travailleurs devenus invalides a la suite d'un accident du travail, sur les mesures prises pour prendre en charge ces derniers et sur les obstacles a leur embauche. L'analyse des reponses fournies par les 88 organismes interroges a montre que la majorite d'entre elles employaient peu de travailleurs invalides. Les invalidites causees par des blessures musculo-squelettiques semblent etre les plus frequentes, suivies par celles liees a une baisse de mobilite physique, puis par celles en relation avec une perte d'audition. Les organismes sondes considerent que la retention d'employes competents et experimentes et le soutien du moral des employes sont les principales raisons qui justifient la mise en reuvre d'un programme de GI. Ils estiment egalement que le manque de postes modifies ou de substitution adaptes constitue le principal obstacle a la mise en place d'un tel programme. Cependant, ces organismes affirment que le comblement de ce type de postes est la mesure qu'ils adoptent le plus souvent, tout en soulevant la question de l'adaptabilite de tels postes aux travailleurs invalides.

This study analyzes the consumption quantities and costs of energy, water, and gas for a sample of 10 conventional and 20 energy-retrofitted public schools in Toronto over a 5 year study period to establish a benchmark for the consumption of energy in traditional versus more sustainable buildings. Through extensive statistical analysis of the data collected, the study demonstrates that electricity and gas consumption quantities and costs decrease more significantly in energy-retrofitted schools than in conventional schools. Whereas energy-retrofitted schools consume and spend on average as much money on energy as conventional schools, energy-retrofitted schools consume and spend more money on electricity and less money on gas than conventional schools. Energy-retrofitted schools also exhibit stronger and more significant positive relationships between the quantities of electricity, water, and gas consumed per user in those schools and the schools' total number of users than conventional schools. Key words: conventional schools, energy-retrofitted schools, energy, water, gas consumption quantities and costs. La presente etude analyse les quantitees et les couts d'energie, d'eau et de gaz consommes pour un echantillon de 10 ecoles publiques conventionnelles et de 20 ecoles publiques ayant subi des renovations energetiques dans Toronto au cours d'une periode de cinq ans, afin d'etablir une reference pour la consommation d'energie dans les batiments conventionnels par rapport a des batiments plus ecologiques. Grace a une analyse statistique detailleee des donnees colligeees, l'etude demontre que les quantitees et les couts d'electricitee et de gaz consommes diminuent de maniere plus importante dans les ecoles ayant subi des renovations energetiques que dans les ecoles conventionnelles. Alors que les ecoles renovees consomment et depensent en moyenne autant d'argent en energie que les ecoles conventionnelles, les ecoles reenoveees consomment et depensent plus d'argent en electricite et moins en gaz que les ecoles conventionnelles. Les ecoles renovees montrent egalement une meilleure relation beaucoup plus positive entre les quantitees d'electricite, d'eau et de gaz consommeees par utilisateur dans ces ecoles et pour le nombre total d'utilisateurs des ecoles que dans les ecoles conventionnelles. Mots-cles: ecoles conventionnelles, ecoles ayant subi des renovations energetiques, quantites et couts de l'energie, de l'eau et du gaz consommes. [Traduit par la Redaction], 1.

With the massive investment in building new infrastructure, the [...]

The seasonal patterns of fruit availability, dietary quality and group size in the descendant of chimpanzee population on Rubondo Island, Tanzania, are examined. The results have contrasted with the evidence from several endemic chimpanzee sites, indicating that Rubondo chimpanzees might have access to abundant and high-quality foods throughout the year.
