Directions for advancing the study of work transitions in the 21st century

Objectives: The purpose of this article is to share the details, outcomes and deliverables from an international workshop on work transitions in London, Ontario, Canada. Participants: Researchers, graduate students, and community group members met to identity ways to advance the knowledge base of strategies to enhance work participation for those in the most disadvantaged groups within society. Methods: A participatory approach was used in this workshop with presentations by researchers and graduate students. This approach included dialogue and discussion with community members. In addition, small group dialogue and debate, world cafe discussions, written summaries of group discussion and reflection boards were used to bring new ideas to the discussion and to build upon what we know. Findings: Two research imperatives and six research recommendations were identified to advance global dialogue on work transitions and to advance the knowledge base. Occupational justice can be used to support future research directions in the study of work transitions. Conclusions: Moving forward requires a commitment of community of researchers, clinicians and stakeholders to address work disparities and implement solutions to promote participation in work.

COMMUNITY OF ORIGIN EFFECTS ON VIRTUAL BRAND COMMUNITIES PARTICIPANT

The question about the effectiveness of companies in maintaining their own communities versus benefiting from the ones owned by consumers remains open. We examine differences between firm-managed and customer-managed brand communities regarding the impact of perceived psychographic homogeneity, availability of virtual avenues and relationship with the brand on the community's influence on members and the assessments and intentions of community participants. Data were obtained from 555 respondents in two leading Microsoft XBOX brand communities in Brazil. Results indicate that management of the community of origin is the moderator of all considered relationships. Also, the most favorable effects for the company occur in the community that is not directly controlled and managed by the company itself. Brand loyalty, however, is higher for members of the official brand community. Guidelines on how companies can benefit from consumer-managed communities are discussed.

Relationship between space distribution of the benthic macroinvertebrates community and trophic state in a Neotropical reservoir (Itupararanga, Brazil)

The purpose of this work was to verify the benthic macroinvertebrates community responses through environmental factors along a headwater tropical reservoir. Samplings were taken with a Van-Veen grab along the reservoir in littoral and profundal regions and in the headwater, next to the dam and the middle of the reservoir. Samples were taken during both wet and dry seasons. Dissolved oxygen concentrations, electric conductivity, temperature and pH near the sediment have been performed in situ, at every sampling station by using a multiprobe and Secchi disc. Total water phosphorus and chlorophyll a concentrations were analyzed to determine the trophic state index. Sediment's organic matter, total phosphorus, nitrogen concentrations and granulometric composition were measured. In order to verify which environmental variables would have more influence over the benthic macroinvertebrates community, a canonical correspondence analysis (CCA) was performed. The total number of recorded taxa was 28. Among them, the family Chironomidae (Diptera) was the richest group (19 taxa). It can be proposed that the benthic macroinvertebrates community may be influenced by environmental conditions such as nutrient and organic matter availability, as well as dissolved oxygen concentration. Macroinvertebrates are adequate bioindicators of water quality due to their sensibility to environmental changes mentioned before. Chironomus sp, Limnodrilus hoffmeisteri and Branchiura sowerbyi comprises a group that can be considered bio-indicators of eutrophic conditions. A second group can be considered as indicator of mesotrophic conditions. The presence of two or more members from that group which comprises Tanytarsini spp, Fissimentum sp, Pelomus sp and Goeldichironomus sp, like predominant taxa, may indicates mesotrophic conditions.
