Abstract

Purpose

This paper aims to propose and evaluate a pedagogically sound and innovative strategy to teach a higher education course that prepares future professionals to intelligently use information and communication technologies (ICTs) in their personal and professional lives.

Design/methodology/approach

The conceptual framework used for the design of the course was the socio-constructivism and activity theories. The implementation of the course was evaluated using the intrinsic case study methodology by including several instruments.

Findings

The pedagogical strategy proposed proved to be sound, as the evaluation showed that students were able to describe, use and propose innovative uses of a wide range of cutting-edge technologies in their both everyday lives and professional settings; they also had the skills to analyse the opportunities and challenges that these presented. Moreover, students liked this innovative way of learning and ended with a positive attitude towards ICT.

Originality/value

Although several courses prepare students to be digital citizens or use ICT to enhance the teaching-learning process, millennials are ill prepared to use cutting-edge technologies in an innovative, responsible and critical way in their future professions. The course that was designed is original in that it goes beyond preparing digital citizens to prepare professionals in any domain to use ICT in an informed and responsible way. Moreover, it is a documented, successful example of an undergraduate universal course in a highly important current society dimension. The authors believe that its pedagogical proposal could be transferred to courses dealing with other global issues such as the environment, economy and peace.

Abstract

The purpose of this chapter is to shed light on some outstanding patterns of change observed in Spanish agriculture over the last decades, and to discuss the ways in which the productivist rationale is reproduced in them. We start by providing an overall picture of the structural transformations of agriculture revealed by the national statistics, calling attention to the increasing importance of a “hard core” of farms progressing under a rationale of growth and modernization. Later, drawing on the literature, we comment some meaningful trajectories of farm change observed in three selected Mediterranean farming systems, namely horticulture (as an example of a long-consolidated intensive agriculture), vine growing (an orientation which has undergone stunning changes in Spain in recent times), and small ruminant production (an extensive farming system with a high conservation value). The three farming systems are advancing, to a greater or a lesser degree, along intensification, concentration, and specialization pathways. However, the introduction of new elements in the most expansionary farm strategies (such as the participation in quality schemes) will provide interesting elements of discussion of the adaptable nature of productivism and its capacity to accommodate to external opportunities and constrains.

Abstract

This chapter outlines the challenges that research and practice in higher education have faced in measuring students' competences and learning outcomes. Particular attention is given to the systematic and institutional contexts in Germany. Based on the outlined national and international contextual framework, the Germany-wide program “Modeling and Measuring Competences in Higher Education (KoKoHs)” is discussed in terms of its two central working stages, key outcomes and lessons learned. In particular, the central results of the second phase are presented for the first time and integrated into the current state of international research. Based on this analysis, perspectives for further research on student learning in higher education and implications for practice and policy are derived.

Abstract

Purpose

This study investigates consumer reactions to dispensers offering solid packaging-free products (e.g. pasta, lentils, cereals) integrated in a delimitated area in a grocery store. More specifically, the research examines the impacts of the overall appeal of packaging-free solid food product dispensers and their perceived ease of use on consumers' intention to use these dispensers and purchase packaging-free products. Moreover, using a set of variables, different buyer profiles are highlighted.

Design/methodology/approach

The field study for this research was conducted in a delimitated area (i.e. a shop within a shop) dedicated to solid packaging-free products (e.g. pasta, lentils, cereals) in a university cooperative store in the province of Quebec, Canada. A total of 456 buyers and consumers of packaging-free products from this store took part in the field study and completed our survey.

Findings

This study shows packaging-free dispensers' overall appeal and perceived ease of use to be determinants of consumers' intention to use these dispensers and purchase packaging-free products. The Rebus (response-based procedure for detecting unit segments) method highlights the need to consider three buyer profiles (enthusiastic, pragmatic, and sceptical) with different reactions to the specific dispensers used by retailers for packaging-free products.

Originality/value

This study focuses on buyers' reactions to packaging-free dispensers in stores, during the purchase process, whereas previous ones highlighted the drivers of and barriers to consumer adoption of packaging-free products (before the purchasing process starts). It also points to the need to fine-tune the segmentation of consumers of packaging-free products, which must be based not only on consumers' previous experience or familiarity with these products but also on the integration of their drivers and barriers.

Abstract

Purpose

This study examines Covid-19-related policies as a showcase for priorities in migration governance, the role of the state and employers’ associations, as well as gaps in social security and social protection.

Design/methodology/approach

This paper looks at how immigration interacts with the labour market in the Czech Republic through the prism of the varieties of capitalism framework and its relation to the concepts of labour market segmentation and flexibility.

Findings

The findings show that pandemic-related measures focused on continuously adjusting a legislative framework granting access to third-country workers. However, protective measures that would guarantee migrant workers and their families access to social rights, such as healthcare, were lacking. In this context, several lines of segmentation are observed: between migrant workers in standard employment and those in non-standard employment, when looking at their access to healthcare; between migrants hired directly by employers and those working through temporary agencies in terms of their wages, stability and protection; and, at a sectoral level, between the skilled workforce and migrants that are pushed to low-qualified poorly paid, and routinised jobs.

Originality/value

This paper expands the existing literature on the preferences and influence of governments, employers and trade unions regarding the demand for foreign labour in varieties of capitalism by adding the perspective of a Central European economic model. At the same time, its findings contribute to the understanding that labour market inequalities are not fostered on the supply side of migrant labour, through exogenous societal or cultural characteristics specific to countries of origin, but rather through institutionalised measures, practices and policies in countries of destination.

Abstract

Purpose

The accurate valuation of second-hand vessels has become a prominent subject of interest among investors, necessitating regular impairment tests. Previous literature has predominantly concentrated on inferring a vessel's price through parameter estimation but has overlooked the prediction accuracy. With the increasing adoption of machine learning for pricing physical assets, this paper aims to quantify potential factors in a non-parametric manner. Furthermore, it seeks to evaluate whether the devised method can serve as an efficient means of valuation.

Design/methodology/approach

This paper proposes a stacking ensemble approach with add-on feedforward neural networks, taking four tree-driven models as base learners. The proposed method is applied to a training dataset collected from public sources. Then, the performance is assessed on the test dataset and compared with a benchmark model, commonly used in previous studies.

Findings

The results on the test dataset indicate that the designed method not only outperforms base learners under statistical metrics but also surpasses the benchmark GAM in terms of accuracy. Notably, 73% of the testing points fall within the less-than-10% error range. The designed method can leverage the predictive power of base learners by incrementally adding a small amount of target value through residuals and harnessing feature engineering capability from neural networks.

Originality/value

This paper marks the pioneering use of the stacking ensemble in vessel pricing within the literature. The impressive performance positions it as an efficient desktop valuation tool for market users.
