Brazil has achieved a tremendous, short-term growth in its petrochemical sector. In 1989 it placed eleventh in the world ranking of petrochemical producers. The main factor responsible for this success was the establishment of three integrated petrochemical complexes in which the government stimulated joint-ventures between a state enterprise, national private and foreign corporations: the so-called “tripartite model.” In this model, foreign partners should provide the necessary technology, state enterprise financial capital and access to raw materials, and the national private bouregoisie legitimacy to the state, as well as, access to the Brazilian market. The tripartite model promoted the creation of several small, single-product petrochemical firms without entrepreneurial scale to carry out efficient R&;D activities. The result is that the Brazilian petrochemical sector is at risk of becoming technologically static and, consequently, uncompetitive; hampering further national capital accumulation. The R&;D system, originally designed to complement the inventive activities of firms, was based on government research centers. In 1988, a new institutional design was proposed, based on a research center managed by the state holding company PETROQUISA. The conception changed from state intervention toward shared responsability by stockholders. This institutional change opens two basic questions: Given that the locus of innovation in this industry has been historically located in the firm, can any other institutional arrangement substitute it?; and, will it be possible, given the government privatization program, to develop a R&;D system on the assumption that stockholders are willing to share the cost of R&;D activities? This article addresses these two questions. 相似文献

The mass media are an important source of social understandings and representations. The growing genre of audience discussion programmes functions as a public forum for airing opinions on issues of social concern. The genre is structured so as to involve viewers, to validate ordinary experiences and to express opinion. Four programmes on drunk driving were analysed for the causal explanations they offer viewers. The causes, effects and causal interconnections used within each programme were analysed, and networks of the overall representations of drunk driving were constructed. These showed a broad consensus of causes and effects across programmes, but different explanations in terms of locus, stability and controllability. Programmes typically offered lists of important factors, rather than structured arguments, despite the debating framework. There was an emphasis on external, stable, controllable causes in the programmes. 相似文献

We examined the impact of intergroup similarity on two aspects of intergroup relations. Drawing on social identity and belief congruence theory, we hypothesized that — at high levels of intergroup similarity — increasing similarity has dual, seemingly opposed effects: It increases ingroup favouritism in evaluations but also increases readiness for social contact with the outgroup. We further hypothesized that both effects are moderated by the strength of individuals' identification with their ingroup. Finally, we hypothesized that there is ingroup favouritism on dimensions relevant for defining the group, but outgroup favouritism on dimensions irrelevant for this purpose. One hundred and forty-nine students from two prestigious high schools, who were assigned to one of three levels of manipulated similarity between their schools, evaluated both schools on dimensions relevant and irrelevant to the school context and expressed their readiness for social contact with the other school. Ingroup favouritism appeared on relevant dimensions and outgroup favouritism on irrelevant dimensions. As predicted, for those highly identified with their ingroup, intergroup similarity led to greater ingroup favouritism in evaluations on relevant dimensions but to increased readiness for outgroup social contact. Implications for interpreting inconsistent results of past research and for specifying conditions for intergroup bias are discussed. 相似文献

Previous research in the happy victimizer tradition indicated that preschool and early elementary school children attribute positive emotions to the violator of a moral norm, whereas older children attribute negative (moral) emotions. Cognitive and motivational processes have been suggested to underlie this developmental shift. The current research investigated whether making the happy victimizer task less cognitively demanding by providing children with alternative response formats would increase their attribution of moral emotions and moral motivation. In Study 1, 93 British children aged 4–7 years old responded to the happy victimizer questions either in a normal condition (where they spontaneously pointed with a finger), a wait condition (where they had to wait before giving their answers), or an arrow condition (where they had to point with a paper arrow). In Study 2, 40 Spanish children aged 4 years old responded to the happy victimizer task either in a normal or a wait condition. In both studies, participants' attribution of moral emotions and moral motivation was significantly higher in the conditions with alternative response formats (wait, arrow) than in the normal condition. The role of cognitive abilities for emotion attribution in the happy victimizer task is discussed. 相似文献

Sixty-two managers and human resource consultants rated a series of genuine résumés with covering letters. The résumés were manipulated to contain varying amounts of information about the candidate’s knowledge, skills and abilities (competency statements). This information appeared at different locations in the résumé and covering letter. In addition, half the managers were provided with extra job requirement details beyond the job advertisement. Managers rated the candidate résumés for candidate suitability, decision to interview and overall ranking. The inclusion of competency statements resulted in higher manager ratings. However, the location of the competency statements did not influence ratings given to résumés. Further, the extra information provided to managers did not influence their ratings. The results replicate and extend an earlier study by Earl, Bright and Adams (1998) and challenge the idea that selection decisions are largely based on the notion of applicant fit. The results suggest that the inclusion on the résumé of statements that address job competencies even in a general fashion will boost an applicant’s chances of being short-listed. 相似文献

This study was designed to analyze the knowledge, misconceptions, and lacks about Attention Deficit Hyperactivity Disorder (ADHD) in a sample of 193 teachers, as a replication of the study carried by Sciutto, Terjesen and Bender in 2000. Teachers completed the Knowledge of Attention Deficit Hyperactivity Disorder (KADDS) (Spanish version), adapted by the authors of this research, to measure knowledge of ADHD in three content areas: general knowledge, symptoms/diagnosis, and treatment. Results indicated an average of correct responses of 31.67, 63.88 and 40.46% in general knowledge, symptoms/diagnosis and treatment, respectively. Teachers displayed significantly more knowledge in the Symptoms/Diagnosis scale than in the other scales. Their knowledge correlated positively with: years of experience with hyperactive children, number of hyperactive pupils in their classrooms, and level of perceived self-efficacy. These findings are consistent with those obtained by Sciutto and colleagues. 相似文献

In choice reaction time tasks, subjects speed up before making an error, but slow down afterward to prevent the occurrence
of a new error. In some trials, the correct response is preceded by an incorrect electromyographic (EMG) activation too small
to reach the response threshold. In this article, we show that these incorrect EMG activations give rise to the same sequential
effects as overt errors: Before a trial containing an incorrect EMG activation, subjects speed up, whereas after that trial,
they slow down. These activations reflect errors that have been detected, inhibited, and corrected in time. As such, they
index the involvement of online executive control. 相似文献

Referring to the work of Bruchon-Schweitzer & Ferrieux (1991) and Balicco (1999), the present study describes the recruitment practices of different types of organizations (N=327, 134 consulting companies and 193 temporary placement firms). We hypothesised that job position and recruiter characteristics (sex, age, level and type of education, status, and recruitment experience) would influence the use of selection techniques. Results revealed that choice of selection techniques is not based on a scientific evaluation of applicants. Job position seems to strongly determine use of personality assessment techniques. Further, recruiter characteristics only seem to determine choice of less valid techniques. In the discussion, a theoretical model of choices made by recruiters and some courses of action are proposed. 相似文献
