Abstract

An experimental study of the mechanical behavior of fused‐deposition (FD) ABS plastic materials is described. Elastic moduli and strength values are determined for the ABS monofilament feedstock and various unidirectional FD‐ABS materials. The results show a reduction of 11 to 37 per cent in modulus and 22 to 57 per cent in strength for FD‐ABS materials relative to the ABS monofilament. These reductions occur due to the presence of voids and a loss of molecular orientation during the FD extrusion process. The results can be used to benchmark computational models for stiffness and strength as a function of the processing parameters for use in computationally optimizing the mechanical performance of FD‐ABS materials in functional applications.

Abstract

Analytical/Computational models for the fused deposition (FD) material stiffness and strength as a function of mesostructural parameters are developed. Effective elastic moduli are obtained using the strength of materials approach and an elasticity approach based on the asymptotic theory of homogenization. Theoretical predictions for unidirectional FD‐acrylonitrile butadiene styrene materials are validated with experimentally determined values of moduli and strength. For moduli predictions, the results were found to be satisfactory with difference between experimental and theoretical values of less than 10 percent in most cases.

Abstract

Fused‐deposition (FD) is a robotically controlled “fiber” extrusion process that produces a new class of materials with a variety of controllable mesostructural features related to fiber layout and the presence of voids. Mesostructural features of importance to the stiffness and strength of unidirectionally extruded materials were characterized as a function of the processing variables. Samples were made using the Stratasys FDM1600 Modeler with the P400 acrylonitrile‐butadiene‐styrene plastic. Results showed that the void geometry/density and the extent of bonding between contiguous fibers depended strongly on the fiber gap and extrusion flow rate. Settings for minimum void and maximum fiber‐to‐fiber bonding were determined. Void and bond length densities in the plane transverse to the fiber extrusion direction varied from 4 to 16 per cent and 39 to 73 per cent respectively. The results quantify the important mesostructural features as a function of the FD process variables and are expected to find use with other FD materials.

Abstract

Purpose

Recently, the application of quality management systems (QMS) in educational institutions has become widespread, in an effort to improve diverse processes and results in schools. However, there are very few studies that enable us to confirm whether these QMS bring true changes that are sustainable over time and lead to improvements in these institutions.

Design/methodology/approach

This study thus aims to assess the impact of the implementation of ISO:9001 standards on school climate and on the satisfaction of the members of the educational community at 80 Spanish preschools, primary and secondary schools in different autonomous communities.

Findings

The analyses performed show conclusive results regarding the impact of ISO:9001 standards on teachers' involvement in improving the school's climate, conflict resolution by the management team and in families' involvement and satisfaction with the school. However, no apparent evidence was found of the impact on relations among teachers, conflict resolution among staff members and the perception of satisfaction by the teachers themselves.

Research limitations/implications

We must bear in mind that the results and conclusions obtained are based on the instrument developed for this study, where it has been the members of the schools themselves who have assessed the changes they have perceived or that have taken place. However, due to the limitation of the instrument, it could be complemented in future research with external evaluations that could complement the results obtained in the present study.

Originality/value

Furthermore, greater impact of the ISO standards was identified in schools from certain regions (Valencia and Andalusia), in state-assisted private schools, in smaller schools and in institutions which have been implementing the QMS for longer periods of time. The management team also perceived a greater improvement in climate than did teachers.

Abstract

In this survey we present (after an Introduction) a guide to the major doctrinal trends of Spanish accounting of the period, classified in various categories: different views of the scientific nature of accounting, dominant theories, purposes of accounting, special areas, views on classification and on the recording of transactions, views on valuation and depreciation, cost accounting, inflationary issues, auditing, accounting terminology, historical concerns, and the practical orientation of publications. A separate section offers further details about prominent Spanish scholars; it is followed by the conclusion. The latter indicates that during the period under investigation, Spanish accountants contributed little to novel accounting thought, but strongly relied on French and Italian doctrines, though neglecting German ideas. Despite of this, Spanish accountants were aware of many theoretical and instrumental novelties of the day, and applied them without substantial delay to their own environment.

Abstract

Purpose

Different studies relate the presence of depression to lower cognitive performance and higher functional dependence in older people; however, this is not entirely clear. The purpose of this study is to validate the existence between the association of these conditions.

Design/methodology/approach

Cross-sectional and descriptive study was conducted in which the memory, metamemory and global functionality test performance of depressed and non-depressed participants was compared between two groups, one cognitively healthy and other with cognitive decline. The participants were 420 older adults, with an average age of 69 and five years of schooling.

Findings

The importance of describing cognitive performance in older adults with depression may provide evidence to support an adequate differential diagnosis and the design of an adequate future therapeutic plan. Identifying and preventing depression in the elderly can improve health and well-being in the elderly.

Originality/value

Depression is a prevalent and highly disabling disease. When it is suffered by an older person, it is associated with higher mortality, functional dependence, poor physical health, worse quality of life indicators and psychological well-being. In the elderly, the clinical diagnosis of depression is difficult, as it has a high comorbidity and is often confused with other health conditions prevalent during older adulthood.

Abstract

Consumer behavior has evolved because of technological development. Nowadays, consumers carry out the different stages of the decision-making process by combining multiple devices which has been defined as multi, cross and omnichannel behavior. These behaviors have attracted the attention of academics and become a hot topic in literature. As a result, vast amounts of studies on the subject need to be revised and clarified. Thus, the aim of this chapter is to synthetize the primary academic literature that analyzes multi, cross and omnichannel behavior from the consumer point of view. To do that, first, the main concepts (multi, cross and omnichannel) and their differences are clarified. Second, the major findings of channel mix literature regarding the topics, channel scope and theories are exposed and described. Third, the opportunities and future lines of research are presented. This chapter contributes to the literature by clarifying the conceptualization of multi, cross and omnichannel behaviors; offering a complete picture of the main topics, channel approaches and theories addressed in channel mix literature; and presenting future research opportunities and open research questions in a channel mix context that could serve as a starting point to build further research.

Abstract

Purpose

A growing number of schools are now implementing quality management systems (QMS). As a result, studies are being conducted to assess the educational benefits of these systems and their capacity to identify areas for improvement in school processes and performance. The purpose the present study is to assess the impact of ISO:9001 implementation on teaching-learning processes in the classroom, and in schools with at least three years’ experience of applying this standard.

Design/methodology/approach

To this end, a questionnaire was administered to a final sample of 2,185 subjects from 80 pre-school, primary and secondary education schools in the regions of Madrid, Castile and León, Andalusia and Valencia (Spain).

Findings

The results show that ISO:9001 implementation yielded a higher than average impact on teaching-learning processes. Specifically, improvements were observed in the subdomains of tutorials, evaluation and classroom teaching methodologies as a result of implementing this QMS.

Originality/value

This impact was higher in state-subsidized private schools in Valencia and Andalusia with over nine years’ experience of ISO:9001 in schools with internal funding plans and in those with fewer than 29 teachers on the staff.

Abstract

This paper addresses the extent to which culture is affecting the adoption of global human resource management (HRM) practices by Spanish organizations. One of our main objectives was to offer a thorough review of the recent empirical evidence regarding HRM practices in Spanish organizations. Another goal was to discuss these findings in light of the Spanish culture in order to identify possible cultural barriers to the adoption of global HRM practices. Our results suggest that Spanish organizations are slowly adopting global practices; however, many traditional practices remain. We suggest that the cultural variables of low future orientation, high power distance, and low institutional collectivism may exert continuing pressures that will hinder the adoption of certain global HRM practices.

Abstract

In this chapter, we analyse the role of women in armed Basque nationalist and separatist terrorist group Euskadi Ta Askatasuna (ETA) from a gender perspective. ETA women were essential agents in the armed conflict, but their image in the mass media and society has been very different from that of their male colleagues (Rodríguez Lara, 2017). Also, their role in the terrorist gang has described a sexually based functional specialisation. In addition, this chapter seeks to contribute to the area of feminist studies on women and political violence. Women's role in one of the most important armed nationalist groups in Europe, ETA, stands as a suitable case study to understand how the mass media (press, journalism), audiovisual content, and social representations of ETA have portrayed these women. The final conclusion of this chapter is that women were not portrayed in the same way as their male colleagues. Women of ETA were doubly penalised because they were women and because they were terrorists.
