AbstractStandardized curricula define the set of skills that must be trained within a training occupation and thus are a key regulatory element of apprenticeship systems. Although clear economic rationales support the usage of such curricula, they necessarily impose costs, especially on firms that train apprentices, but do not use the full set of skills in their productive process and/or train other skills that are not covered by the curriculum. In this paper, we identify the trade-offs involved in setting up training curricula and use data from the most recent survey on the costs and benefits of apprenticeship training among Swiss firms to quantify the associated costs to training firms. On average, training firms state that they do not use 17% of the training content prescribed by the relevant curriculum, and 11% of the companies train additional skills not covered by the curriculum. We show that both kinds of misfit are associated with higher training costs and lower productive output from apprentices. This shows that the regulator imposes costs on firms in order to guarantee broad skills development for apprentices. It also cautions against overly broad curricula that may impose disproportionate costs on firms.

In the recent years, plastic-based shopping bags have become irregular and progressively replaced by compostable ones. To be marketed, these “new plastics” must possess suitable requirements verified by specific bodies, which grant the conformity mark, and the approved physicochemical properties are periodically verified. The fast, inexpensive, non-destructive, easy to use, and reproducible Fourier-Transform infrared (FTIR) spectroscopy is a technique routinely applied to perform analysis in various industrial sectors. To get reliable information from spectral data, chemometric methods, such as Principal Component Analysis (PCA), are commonly suggested. In this context, PCA was herein performed on 4, 5, and 21 × 3251 matrices, collecting the FTIR data from regular and irregular shopping bags, including three freshly extruded films from the Italian industry MecPlast, to predict their compliance with legislation. The results allowed us to unequivocally achieve such information and to classify the bags as suitable for containing fresh food in bulk or only for transport. A self-validated linear model was developed capable to estimate, by acquiring a single FTIR spectrum if, after the productive process, the content of renewable poly-lactic-acid (PLA) in a new produced film respect the expectations. Surprisingly, our findings established that among the grocery bags available on the market, irregular plastic-based shopping bags continue to survive.

This qualitative case study of travel journalism in the USA explores how freelancers produce on speculation because publications do not contractually guarantee pay or advanced resources for travel. Freelance travel journalists therefore experience their work as an investment into an uncertain return in an undefined future. This article shows how such speculation manifests itself as a new productive process and relations of organisational externalisation in lean capitalism. Examining the changing obligations between freelancers and publications without assignment-contracts, this study argues that speculation presents the obfuscation of production. It externalises the risks of production onto the freelancer; reduces organisational control over production; and changes occupational norms and practices.

AbstractIn the present research work nickel (Ni) and titanium (Ti) elemental powder with an ostensible composition of 50% of each by weight were mechanically alloyed in a planetary high energy ball mill in diverse milling circumstances (10, 20, 30 and 60 h). The inspection exposed that increasing milling time leads to a reduction in crystallite size, and after 60 h of milling, the Ti dissolved in the Ni lattice and the NiTi (B2) phase was obtained. The lattice strain of ball milled mixtures augmented from 0.15 to 0.45 at 60 h milling. With increase in milling time the morphology of pre-alloyed powder changed from lamella to globular. Annealing of as-milled powders at 1100 K for 800 s led to the formation of NiTi (B19′), grain growth and the release of internal strain. The result indicated that this technique is a powerful and highly productive process for preparing NiTi intermetallic compounds with a nano-crystalline structure and appropriate morphology.

Steel Re-Rolling mill is the second most important steel forming industry in India. The manufacturing process of steel re-rolling from ingots to finished products has high energy consumption and it directly affects productivity and manufacturing cost. Measuring the productivity of the process can unleash the low productive process, which leads towards rectification for increasing the productivity of lean area. The productivity of Steel Re-Rolling mill is measured by Performance Objective – Productivity model. Key performance areas were identified by intensive survey and process of prioritization was carried out. The actual values of the Key performance Areas of the system were compared with the objectivated values of the system. The outcomes lead to Productivity Index of the system, sub-system and key performance areas of the process revealing the areas with low-performance index which have the highest impact on productivity of the process. The energy subsystem is having the lowest performance index and is the main source of loss and recommendations are made to increase the productivity of energy sub-system.

This paper analyzes the behavior of marginalized microenterprises under an imperfect competition framework, where said economic units are capable of fixing a price above their marginal costs which allows them to survive and even be profitable despite their typical operating conditions. To prove this, we use an econometric model that considers the Lerner index as a variable dependent on a set of qualitative variables previously classified in accordance to their area of influence. We conclude that these microenterprises are capable of being profitable and operate with market power through their advertising and sales strategies and the flexibility in their productive process. In any case the pricing power is highly influenced by the socioeconomic conditions of the market in which it operates.

Methodological Principles

To overcome the crisis of the modern school institution, it is necessary to qualitatively rethink its foundations and to design fundamentally new approaches to implementing the educational program. The theoretical and methodological bases of the concept of a new type of school as a development practice, based on the provisions of Russian cultural-historical psychology and the activity approach are presented. The purpose of the work is to consider in the modern context the key theoretical provisions of Russian psychology and to formulate the methodological principles arising from them, which set the conditions for organizing the educational process, thus ensuring the transition from theory to practice. The key concepts of the school model are development, agency and collaboration: infinite development is formulated as the supreme goal and value of the school, the development of the position of agency is considered as the main productive process, and collaboration is the main professional principle. Eight basic principles are formulated as follows: intent - implementation - reflection as a methodological scheme for organizing school processes, the principle of multidimensional development, the principle of equal importance of school activities, the principle of congruence, the principle of organizing the educational space as a space for growing up, the principle of fellowship of practices and the development-oriented approach to evaluation. Thus, the article presents the authors view of the school as a scientifically grounded anthropological practice. The implementation of the concept, which has already begun in Russia, is an experiment that will make it possible to verify these theoretical and methodological provisions.
