Large scale communication networks—Design and analysis

The paper discusses the problem of design and analysis of large scale communication systems. An iterative process, composed of a minimum cost network design algorithm and a network performance algorithm, is presented for the solution of these problems. Computational considerations, using these algorithms, are discussed.     

Assessing the effectiveness of strategic planning

This paper describes a method for assessing the effectiveness of strategic planning systems in terms of the results actually observed subsequent to planning activity. The paper explains in particular how, in making the assessment, one might cope with the fact of environmental change subsequent to the setting of planned goals. This ends oriented approach to measuring effectiveness is shown to be complementary to process oriented approaches and is illustrated by an example from the coal industry.     

Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands

Elissen AMJ, Van Raak AJA, Derckx EWCC, Vrijhoef HJM. Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands Faced with rising homelessness, countries around the world are in need of innovative approaches to caring for those without shelter, who, more often than not, suffer from severe health problems. We conducted a case study of an innovative Dutch Primary Care for the Homeless (PCH) programme to gain insight into clients' demographic characteristics, health problems and service use, and to develop an explanation for its success in increasing the latter. Our analyses are based on a combination of quantitative and qualitative data. The results of the study suggest that the success of the PCH programme can be explained by the providers' pragmatism and will to adapt their mode of care provision to the behavioural patterns and needs of their homeless clients.     

Political tolerance among adolescents towards homosexuals in Spain

This paper studies the willingness that an adolescent has to extend human rights to homosexuals. This willingness defines the concept of political tolerance towards homosexuals. Results of this study show that the rights that adolescents are less willing to extend to homosexuals are those more related to the activities that homosexuals do to recover their rights, as the right of demonstrating on the street. This study also pretends to find those variables more related to political tolerance towards homosexuals. Self-esteem, political experience, support for democratic norms and identification with a group of friends are positively related to political tolerance towards homosexuals, whereas support for violent groups or the identification with a religious group are negatively related.     

Sexism and Racism in a Spanish Sample of Secondary School Students

The aim of this article was to investigate the relationship between sexism and racism in a Spanish sample as well to study common psychological patterns. 406 secondary school students responded to a questionnaire packet: Ambivalent Sexism Inventory towards women (Glick and Fiske, 1996), Ambivalent Sexism Inventory towards men (Glick and Fiske, 1999), Sexual Role scale (Moya et al., 1991), Blatant and Subtle Racism scale (Pettigrew and Meertens, 1995), Self-esteem (Rosenberg, 1965), Parwaise Comparison Value Survey (Oishi et al., 1998), and Big Five (Benet-Martínez and John, 1998). In general terms measures of sexism were correlated with racism measures. However, the idea that there are similar elements underlying sexism and racism is more evident in sexim towards women than sexism towards men.     

The Social Dynamics Channelling Latina College Graduates into the Teaching Profession

Sociologists examine the persistence of occupational sex segregation in two primary ways, vertically (within occupations) and horizontally (across occupations). Feminist scholars analysing gender and race inequality within work organizations have used ‘glass escalator’ and ‘glass barriers’ to document men's experiences in occupations where women concentrate, falling under the vertical epistemology. These race and gender theories are crucial to our understanding of workplace inequities, but they only address privilege or discrimination once women have entered or try climbing the work organization. Based on interviews with 40 Latina teachers in Southern California, this paper examines the point of occupational entry, and explains why college‐educated Latinas, the daughters of working‐class Latino immigrants, are disproportionately entering the teaching profession in the United States. We suggest that Latinas are socially channelled into the teaching occupation, and show how collective family considerations inform agency and occupational decision‐making for these women, resulting in a type of glass ceiling shaped by family and social class. The paper concludes with a discussion of the implications of collective‐informed agency for future studies of upwardly mobile Latinas in the professions.
