Fatores de estresse relacionado ao trabalho: as vozes dos atendentes de telemarketing

A elevada rotatividade e o crescimento do número de casos de transtornos mentais entre os atendentes de telemarketing é resultado do trabalho penoso a que esses trabalhadores são submetidos. Este artigo teve por objetivo analisar os fatores organizacionais e psicossociais relacionados ao estresse e sofrimento psíquico percebidos pelos atendentes de uma empresa de telemarketing. Foi aplicado um questionário de avaliação do estresse no trabalho e criou-se um grupo focal para a discussão e identificação das principais categorias relacionadas com o sofrimento psíquico desses trabalhadores. A falta de controle e a falta de autonomia foram os principais fatores de estresse e sofrimento psíquico nos dois instrumentos, tanto no quantitativo, quanto nos grupos focais (qualitativo), ambos adotados neste estudo. Na percepção dos atendentes, a falta de transparência nos critérios de promoção e reconhecimento, a precariedade do suporte e o apoio da chefia e os relacionamentos conflitantes na organização pesquisada também influenciam negativamente a saúde mental destes sujeitos.The high turnover and the increased incidence of mental disorders among telemarketing workers result from the burdensome work they are submitted to. This article evaluated the organizational and psychosocial factors related to stress and psychic suffering perceived by the attendants of a telemarketing company. A questionnaire was used to assess stress at work and a focal group was created for the discussion and identification of key categories related to psychological distress among these workers. The lack of control and autonomy were the main factors related to stress and psychic suffering in both quantitative and qualitative instruments used in this study. In the perception of the attendants, the aspects related to career and recognition, support and leadership, relationships and peer support are relevant to the mental health of these individuals

The complete genome sequence of Chromobacterium violaceum reveals remarkable and exploitable bacterial adaptability

Chromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spread utilization of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in addition, a series of previously unknown but important enzymes and secondary metabolites including paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multiple chitinases, and proteins for the detoxification of xenobiotics that may have biotechnological applications

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
