Globalização e reconfigurações do mercado de trabalho em Portugal e no Brasil

The article discusses the processes of transformation that are underway in the contexts of Portuguese and Brazilian labor markets. Starting with a reflection on globalization and some of its impacts - resulting from technological changes and the introduction of new information technologies, accompanied by an economic policy that favors deregulation and flexibility of labor relations -, it analyses some trends regarding precarious employment in both countries. The discussion is grounded on the assumption that job precariousness, which currently affects all age and professional groups, is not anymore a mere cyclical and peripheral phenomenon.

As possibilidades interativas do telejornalismo na TV digital aberta no Brasil

This paper presents proposals for the use of interactivity in the telejournalism in an open television broadcaster and the consequences of this use. The issues raised here go beyond technical issues and also addresses issues of theoretical field. The fundamental purpose of this paper is to present interactive possibilities in television journalism as a way of providing this television format tools to keep up with technological changes in the field of production and sharing news. However, by using these tools, the television news is enabling reversal of two important hypotheses that describe the analog television journalism: Scheduling Hypothesis and the Spiral of Silence. To reach your main goal we used a theoretical framework relevant to the issues addressed here and a survey of some interactive applications for digital television developed specifically for TV newscast. From this instrument, we selected two sets of interactive features that can be employed, in general, newscasts, and how these features relate to the hypotheses of Scheduling and Spiral of Silence.

Use of a new milk-clotting protease from Thermomucor indicae-seudaticae N31 as coagulant and changes during ripening of Prato cheese

Prato cheeses were manufactured using coagulant from Thermomucor indicae-seudaticae N31 or a commercial coagulant. Cheeses were characterised using the following analysis: yield; fat; acidity; moisture; ash; salt; pH; total nitrogen; total protein; NS-pH 4.6/NT100; NS-TCA 12%/NT100; casein electrophoresis; and RP-HPLC. The results were statistically analysed and revealed that the proteolytic indices were not significantly different throughout the 60 days of ripening of cheeses made with either coagulant. Even though there were some quantitative differences in the peptide profile of cheeses, the enzyme from T. indicae-seudaticae N31 was used in the production of good quality Prato cheese without having to change the established technological parameters of the process. © 2011 Elsevier Ltd.

Technological transition and the new skills required by the agribusiness sector

Adoption of new technologies throughout the agribusiness chain is necessary to meet the higher food and fuel needs of a growing and wealthier population. However, modern technologies require the development of new skills and changes in working patterns and relationships at all levels of the organization. Companies that invest in technology without investing in human capital development will not reach their full potential. © 2012 International Food and Agribusiness Management Association (IFAMA).
