Infusing Career Development to Strengthen Middle School English Language Arts Curricula

An approach is presented for strengthening middle school standards‐based English language arts (ELA) classroom instruction by infusing theory‐ and research‐supported career development constructs and practices. Over an 8‐week period, 90 urban 7th graders participated in an integrated ELA–career development curriculum. Career agency emerged as an important construct for students. It was related to key markers of ELA achievement (i.e., standardized test scores, grades, and positive change in 6th‐ to 7th‐grade test scores) and elaborated on in nuanced ways by students in their written narratives. Four themes related to career agency were identified in student writings: time perspective, challenges of self‐direction, career development, and social and emotional development. Advantages for students and schools related to synergy, scale, and sustainability are discussed.     

Manufacturer–Retailer Negotiations in the Presence of an Oligopolistic Input Market

When a manufacturer relies solely on its own inputs in making products, the focus of negotiations between the manufacturer and retailer is exclusively on profits in the output (retail) market. In such cases, absent retail competition concerns, standard two‐part tariff negotiations set the per‐unit wholesale price equal to marginal cost, and require fixed transfers from the retailer to the manufacturer. In this article, we recognize that manufacturers often rely on imperfectly competitive markets for at least some inputs. Incorporating this seemingly natural feature has profound implications for manufacturer–retailer negotiations since it shifts their focus from being exclusively on output markets to one that balances strategic concerns in both input and output realms. The article's main result is that the added need to discipline input prices can lead the manufacturer and retailer to write contingent contracts that are cost‐plus and prescribe lump‐sum slotting allowances (i.e., fixed transfer from the manufacturer to the retailer).     

Towards a 'Movement Society'? On the possibilities of institutionalizing social movements

Social movements come into existence only on the basis of certain preconditions. The concurrence of distinct factors on the levels of individual experience, collective framing and societal structure favour the emergence and stabilization of social movements. Drawing on a model that links these three levels with aspects of problematization, mobilization and stabilization, we argue that there is a growing probability for social movements to come into existence. This probability stems mainly from a set of macro-structural trends and their problematic effects that can be interpreted in terms of differentiation theory. Instead of encompassing and stable class movements as represented, for example, by the labour movement, we expect a multitude of more situationally bound movements that vary considerably in their themes, social bases and forms. It is precisely this heterogeneity of movements that is an enduring feature of contemporary Western societies.     

Towards the price of leasing online

We consider online optimization problems in which certain goods have to be acquired in order to provide a service or infrastructure. Classically, decisions for such problems are considered as final: one buys the goods. However, in many real world applications, there is a shift away from the idea of buying goods. Instead, leasing is often a more flexible and lucrative business model. Research has realized this shift and recently initiated the theoretical study of leasing models (Anthony and Gupta in Proceedings of the integer programming and combinatorial optimization: 12th International IPCO Conference, Ithaca, NY, USA, June 25–27, 2007; Meyerson in Proceedings of the 46th Annual IEEE Symposium on Foundations of Computer Science (FOCS 2005), 23–25 Oct 2005, Pittsburgh, PA, USA, 2005; Nagarajan and Williamson in Discret Optim 10(4):361–370, 2013) We extend this line of work and suggest a more systematic study of leasing aspects for a class of online optimization problems. We provide two major technical results. We introduce the leasing variant of online set multicover and give an \(O\left( \log (mK)\log n\right) \)-competitive algorithm (with n, m, and K being the number of elements, sets, and leases, respectively). Our results also imply improvements for the non-leasing variant of online set cover. Moreover, we extend results for the leasing variant of online facility location. Nagarajan and Williamson (Discret Optim 10(4):361–370, 2013) gave an \(O\left( K\log n\right) \)-competitive algorithm for this problem (with n and K being the number of clients and leases, respectively). We remove the dependency on n (and, thereby, on time). In general, this leads to a bound of \(O\left( l_{\text {max}} \log l_{\text {max}} \right) \) (with the maximal lease length \(l_{\text {max}} \)). For many natural problem instances, the bound improves to \(O\left( K^2\right) \).     

Ende des Elends

In the German speaking Sociology of the Industry the debate about an alleged crisis of the discipline itself continues. Yet recent contributions demand structural surmounting of this crisis through reminiscence and consecutive re-wording of ancient theories — particularly Marx’ theory. The article is considered as an actual contribution towards a conceptual endeavour of the re-wording of the Sociology of the Industry. To begin with, it will be demonstrated that the claim for an action-theoretical re-interpretation endeavour of the re-wording of Marx’ fundamentals falls on prolific grounds — as the Sociology of Work and Industry has already contributed specifically towards the sociological Action-Theory with the concept of subjectifying work action. In addition, the paper shows that the claimed societal-theoretical re-foundation demands a dialectic re-animation of Marx’ fundamentals (perhaps not just) of the Sociology of Work and Industry, and that it seems solvable with the category of work capacity. Thereby an actual contribution to the recent once more claimed extension of the work notion is presented. The article thereby critically continues the debate which has been taking place.     

‘Valid’ empirical measurement of quality of life?

Results of empirical quality of life studies, undertaken hitherto, are subjectively influenced to a considerable extent by the researchers who try to measure the ‘quality of life’. In substantiation of this allegation it is shown on the basis of empirical data that the results are highly influenced, among others, (1) by the selection of indicators, (2) by the aggregation of indicators to one element, (3) by the weighting or non-weighting of the indicators, (4) by the indicator weigths given by different groups, (5) by employing different measurement techniques. Remarkable progress in empirical measurement could be made by the employment of objective indicators which are weighted by different groups (e.g., citizens, experts, decision makers, etc.). This approach can be called a ‘weighted objective indicator’ approach. In the second half of the article the proposal is made to measure infrastructure disparities both in physical and monetary terms. This permits a comprehensive assessment of the infrastructure's deficits and surplus on the level of indicators, subconcerns, and concerns.     

Student Evaluations and Faculty Members with a Disability

Résumés of hypothetical prospective faculty members were distributed to a sample of 307 university students. They were systematically manipulated as to whether the candidate had a disability. The students were asked to rate the hypothetical prospective faculty members on the basis of teaching and professional characteristics as well as whether they would sign up for a class with them and would recommend hiring them. In terms of teaching characteristics the students were more positive toward the disabled hypothetical prospective faculty members than the non-disabled. It appears that if hired, a faculty member with a disability will start at a level of student acceptance the same as or higher than that of one without a disability. One of the purposes of an affirmative action program is to bring in the protected group on the same terms as others and this purpose appears to be achievable in regard to disability.     

Scheduling with interjob communication on parallel processors

Consider a scheduling problem in which a set of tasks needs to be scheduled on m parallel processors. Each task \(T_i\) consists of a set of jobs with interjob communication demands, represented by a weighted, undirected graph \(G_i\). The processors are assumed to be interconnected by a shared communication channel, which can be used by jobs to communicate among each other while being processed in parallel. In each time step, the scheduler assigns jobs to the processors and allows any processed job to use a certain capacity of the channel in order to satisfy (parts of) its communication demands to adjacent jobs processed in the same step. The goal is to find a schedule with minimum length in which the communication demands of all jobs are satisfied. We show that this problem is NP-hard in the strong sense even if the number of processors is constant and the underlying graph is a single path or a forest with arbitrary constant maximum degree. Consequently, we design and analyze approximation algorithms with asymptotic approximation ratio \(\min \{1.8, 1.5 \frac{m}{m-1}\}+1\) if the underlying graph G, the union of the \(G_i\), is a forest. For general graphs it is \(\min \left\{ 1.8, \frac{1.5m}{m-1}\right\} \cdot \left( \text {arb}(G) + \frac{5}{3}\right) \), where \(\text {arb}(G)\) denotes the arboricity of G.     

The ICIDH and the Need for its Revision

The International Classification of Impairments, Disabilities, and Handicaps (ICIDH) published and used by the World Health Organization is currently undergoing a revision. Its conceptual basis is the medical model which leads to the medicalization of disability. From this point it is a short step to eugenics and a class-based evaluation of people with disabilities using the concept of 'normal'. People with disabilities are found to be lacking and a burden. The language and the logic of the ICIDH are faulty. It is replete with biased, handicapist language. In its present form and even in its proposed revised form (ICIDH-2) it is a threat to the disability community world wide.
