Development and implementation of new technologies in the steel industry

At each successive stage in the R&D cycle leading to the commercialization of a new technology, management in any industry must reevaluate prospects and make decisions accordingly. However, for the steel industry the difficulties of this kind of decision-making throughout the usually lengthy R&D cycle are heightened by the very nature of the industry. For example, the large scale of its processes and the high capital costs for plants for new processes mean that the progressive scale-ups during a given development may themselves cost millions. From Bethlehem Steel's experience the author cites one new product and two major process developments to illustrate technical and economic considerations that enter into decision-making as R&D moves step by step toward the commercialization of new technology.     

The political and socioeconomic context of legal and illegal Mexican migration to the United States (1942-1984)

The US manpower shortage in industry and agriculture during World War II, combined with Mexico's burden of an excess number of unemployed laborers, provided the basis for serious labor negotiations between the US and Mexico. The result was the Bracero Agreement of 1942, a bilateral agreement involving annual quotas for the temporary hiring of Mexican braceros. On the surface the program worked well. However, there were points of contention between the 2 countries: 1) in opposition to Mexico's policy of placing recruitment centers in the interior of the country, US policy called for placing the centers near the border, to reduce transportation costs; 2) Texas, which received no braceros because of racial discrimination, relied upon illegal aliens for manual labor; 3) Texas flagrantly violated a 1948 agreement when the Border Patrol welcomed aliens across the river despite Mexican officials' threats to close the border; 4) legal braceros were confronted with competition from illegals who were willing to work for a lower wage; 5) in 1954, the Border patrol physically helped aliens across the border, while Mexican policy were physically restraining them; 6) with the conclusion of a new Bracero agreement in March 1954, illegal aliens were no longer needed, so more than 1 million were apprehended and deported to Mexico's interior. The termination of the Bracero Program in 1964 gave new impetus to illegal trafficking and the number of illegals apprehended began to increase steadily in 1965. The migration flow after 1964 was influenced by the following socioeconomic conditions in Mexico: 1) unemployment, 2) very large disparities in income distribution, 3) a discrimination of the rural sector in favor of the urban in the allocation of government funds, and 4) a dependency on foreign capital and technology. Also, it was cheap labor for the US. Neither the US nor Mexico has adopted policies related to either economic development or immigration that would systematically curtail or regulate the flow of Mexican migrants to the US. However, conflicting pressures limit the policy-making process. President Carter was limited in his policy options by the needs of large-scale commercial agriculture. President Reagan's idea of a guest-worker program did not develop into legislation. Mexico's Lopez Portillo administration counted on migration to the US as a substitute for redistributive land reform in its handling of rural political pressures; the migratory flow functioned as an "escape valve" helping to dilute the effects of rapid demographic increase and preserving the status quo.     

Exponential GARCH Modeling With Realized Measures of Volatility

We introduce the realized exponential GARCH model that can use multiple realized volatility measures for the modeling of a return series. The model specifies the dynamic properties of both returns and realized measures, and is characterized by a flexible modeling of the dependence between returns and volatility. We apply the model to 27 stocks and an exchange traded fund that tracks the S&P 500 index and find specifications with multiple realized measures that dominate those that rely on a single realized measure. The empirical analysis suggests some convenient simplifications and highlights the advantages of the new specification.     

Beyond School to Work: Continuing Contributions of Theory and Practice to Career Development of Youth

This response (a) makes a few comments about the articles as a group, (b) briefly highlights the historical context of previous theory-based models for career guidance in schools, and (c) argues that school to work (STW) is not an intellectual but an economic and a political strategy that needs to be examined carefully, especially in relation to students' career needs and theory-based interventions of the recent past.     

The poverty of postnationalism<Emphasis Type="Italic">:</Emphasis> citizenship,immigration, and the new Europe

Over the last decade and a half, in a literature otherwise obsessed with citizenship in all its forms, a broad array of scholars has downplayed, criticized, and at times trivialized national citizenship. The assault on citizenship has had both an expansionary and a contractionary thrust. It is expansionary in that the language of citizenship is no longer linked with nationality, but rather protest politics. An earlier generation of social scientists would have described these actions as lobbying; they have now become “citizenship practice.” It is contractionary in that what one might have thought to be the core of citizenship; nationality, the possession of a nation-state’s passport is viewed as less and less relevant to citizenship. Scholars have dislodged both the substance of citizenship, what it is, and the location of citizenship, where it “happens,” from the nation-state and national citizenship. The article challenges this devaluation of citizenship and the nation-state on empirical, conceptual, and normative grounds. Empirically, scholars, whom I link together under the umbrella term “postnationalists,” have based their anti-statist arguments on evidence that, when subjected to further inspection, wholly fails to support the arguments advanced. Conceptually, postnationalists rely on categories that are confused and untenable, being that national variables are cited as evidence of transnational developments. Normatively, postnationalists have lost the emancipatory thrust that once gave concerns with citizenship real-world purchase.

Work and welfare‐state trajectories in Norway over two decades: Has the goal of getting more people into work been achieved?

In this study, we investigated the work and welfare‐state trajectories of three cohorts of middle‐aged Norwegian inhabitants over a period of two decades (1994–2014). The period of this study is particularly interesting because of an extensive welfare reform that was initiated in 2006 and completed in 2011. We addressed two questions: What were the most typical labour market and welfare‐state trajectories for middle‐aged people over the past two decades, and have they changed? Second, did the work and welfare‐state trajectories of a major target group of the NAV reform – adults with a high risk of health‐related exclusion – change during our observation period? Over the period, we witnessed a sharp drop in the number of people in stable employment. Furthermore, rather than solving the problem of permanent health‐related exclusion from the labour market, policy changes have created a new problem by steering people into temporary and less secure income sources from the welfare state.     

Conflicts and empowerment – a processual perspective on the development of a partnership

Partnership working involving providers and users of social services is highly valued as a means to inform research and practice, yet its effectiveness is debated. Frameworks for measuring and evaluating partnerships are developed, but still there is a need to shed light on micro-practices to gain insight in how partnerships succeed or fail to reach their goals. The context for this qualitative study is a Norwegian governmental funded program, where one goal was promotion of structures for equal collaboration between social work education, research, social service providers and users. The study investigates one local partnership project and how conflicts influenced processes and outcomes. Conflicts were related to the leadership of the group. With a particular look at users’ participation, the findings indicate how emergence and negotiations of conflicts were related to their empowering processes as the project developed. The study underscores the importance of acknowledging conflicts and how these may be complex and interwoven with empowering processes when users are involved, as well as the need to critically examine issues on leadership. The study supports the importance of ethnographic studies in order to understand how a partnership might deliver, as this approach enables enhanced understanding of micro-practices and internal power dynamics.     

Regression Kink With an Unknown Threshold

This article explores estimation and inference in a regression kink model with an unknown threshold. A regression kink model (or continuous threshold model) is a threshold regression constrained to be everywhere continuous with a kink at an unknown threshold. We present methods for estimation, to test for the presence of the threshold, for inference on the regression parameters, and for inference on the regression function. A novel finding is that inference on the regression function is nonstandard since the regression function is a nondifferentiable function of the parameters. We apply recently developed methods for inference on nondifferentiable functions. The theory is illustrated by an application to the growth and debt problem introduced by Reinhart and Rogoff, using their long-span time-series for the United States.
