Introducing new constructs for data modelling and column generation in LP modelling languages

Through popular implementation of structured query language (SQL) and query-by-example(QBE) relational databases have become the de-facto industry standard for data modelling.We consider the indices, sets, and the declarative form of Linear Programming (LP) modelling languages and introduce new constructs which provide direct link to the database systems. The models constructed in this way are data driven and display a dynamicstructure. We then show how this approach can be naturally extended to include column generation features stated in procedural forms within an otherwise declarative modelling paradigm

Labor contracts and flexibility : evidence from a labor markt reform in Spain

This paper evaluates the effects on employment, job turnover and productivity of a labor market reform in Spain that eliminated dismissal costs for fixed-term contracts. Our empirical results are based on a panel of 2356 Spanish manufacturing firms for the period 1982-1993. We postulate and estimate a dynamic labor demand model with indefinite and fixed-term labor contracts. Our estimations use data on severance payments to identify when negative changes in employment have been associated with costly dismissals. Experiments using the estimated model show important positive effects of the reform on employment (between 2.5% and 4.5%) and job turnover (between five and seven percentage points). However, its effects on productivity and the value of a firm are negligible. This contrasts with the sizeable increases in output and v3.Iue under a hypothetical reduction in firing costs for all type of contracts. Compared with this alternative reform, the introduction of temporary contracts leads to excess turnover and employment of workers with low firm-specific experience

Sustaining local audiovisual ecosystems: shifting modes of financing and production of domestic TV drama in small media markets

Various trends, both technological and economic in nature, have led to a shift in the financing and production of serial television fiction (principally television drama and episodic comedy), resulting in pressure on existing financing of TV fiction. These pressures prove especially difficult for small nations and regions, being characterized by restricted markets, a limited number of active players, and barriers for export and scale. For media policy-makers, these transitions invoke a series of new challenges to sustain existing audio-visual ecosystems. Based on a case study of TV fiction in Flanders, and presenting evidence from a financial analysis of 46 TV fiction productions, this article analyses current financing streams, patterns and dynamics of TV fiction in small media markets. It seeks to reveal the composition of budgets and the relative importance of diverse agents and funders involved in TV fiction production. Critical evaluations are then offered as to whether current financing models and policy support mechanisms are fit to tackle the challenges posed by the increasing number of windows and increased fragmentation of TV fiction financing

Organizing Dark Matter: W.A.G.E. as Alternative Worker Organization

Since its founding in 2008, W.A.G.E. (Working Artists and the Greater Economy) has worked to reform the economic habits of US art institutions and of the artists upon whose cultural work these institutions are dependent. Inside a decade, W.A.G.E. went from a small grassroots collective to an internationally recognized, yet lean, organization, which not only advocates for labour standards in the nonprofit art sector, but also develops practical tools to begin the work of doing better by equality in the art world. This chapter positions W.A.G.E. as an example of what Immanuel Ness terms “new forms of worker organization.” Informed by W.A.G.E.-authored texts, media coverage of W.A.G.E., and interviews with the group’s core organizer and programmer, the chapter surveys W.A.G.E.’s strategies for organizing “dark matter,” a concept that Gregory Sholette has repurposed from physics as a metaphor for the majority of artists and activities that populate the art world and uphold and subsidize its most visible and commercially successful figures. W.A.G.E. is explored in five registers: its practice of parrhesia, algorithm of fairness, strategy of certification, post-horizontalist form of organization, and platformization of labour politics. While W.A.G.E. has been tackling dilemmas specific to the nonprofit arts, its strategies hold wider relevance to confronting the challenge of organizing workers who are outside of an employment relationship, who lack access to unions, and for whom the opportunity to be self-expressive or the promise of exposure may be regarded as compensation enough

Communication and leadership skills in the Computer Science and Information Systems curricula: A case study comparison of US and Bulgarian programs

In this paper we present results from our curriculum research on the behavioral educational topics being in the computer science (CS) and information systems (IS) academic programs in two countries USA and Bulgaria. Specifically, we address learning outcomes as they pertain to IT Project Management. Our research reveals that the two countries approach undergraduate education from different vantage points. The US universities provide a flexible general education curriculum in many academic areas and students have the opportunity to strengthen their soft skills before they enter the workforce. Bulgarian universities provide specialized education in main CS subject areas and the students are technically strong upon graduation. Is there a way to balance out this divergent educational experience so that students get the best of both worlds? Our paper explores this aspect and provides possible solutions
