This paper aims to investigate the microstructural anisotropy of Ti-6Al-4V samples fabricated by selective laser melting.

Specimens are fabricated through a Renishaw AM400 selective laser melting machine. Three microstructures (as-built, 850°C annealed and 1,050°C annealed) and two building orientations, parallel (PA) and perpendicular (PE) to the building platform, are considered. Starting from in-depth microscopic observations and comprehensive electron backscattered diffraction imaging, the study addresses non-conventional techniques such as internal friction and electrical resistivity measurements to assess the anisotropy of the fabricated parts.

Microscope observations highlight a fine texture with columnar grains parallel to the building direction in the as-built and 850°C annealed samples. Besides, coarse grains characterized the 1,050°C annealed specimens. Internal friction measurements pointed out the presence of internal stress while storage modulus analyses appear sensitive to texture. Electrical resistivity is resulted to be dependent on grain orientation.

The work uses some novel characterization techniques to study the anisotropy and internal stresses of Ti-6Al-4V samples processed by selective laser melting. Mechanical spectroscopy results suitable in this kind of study, as it mimics the operating conditions of the material.

The purpose of this paper is to design and validate a reliable and comprehensive instrument to assess the influence of sustainable supply chain management (SSCM) practices on sustainable performance in hospitals.

A systematic and mixed-method approach was used to create and validate an instrument for assessing the level of implementation of hospital SSCM practices and the perceived extent of environmental, social and economic performance. This includes the development of preliminary items and the evaluation of content and construct validity. Data from Colombian hospitals was collected. Structural equation modeling was used to test the structural model.

During the content validity phase, an initial version of the questionnaire consisting of 88 items was generated. This version was qualitatively and quantitatively reviewed and assessed by six academicians and two hospital practitioners, based on criteria of sufficiency, clarity, relevance and coherence. The computation of both individual and scale content validity indices, along with the qualitative feedback, led to the refinement of the questionnaire. The subsequent phase of construct validity involved the implementation of a pilot test with 55 responses gathered from Colombian hospitals. By considering the metrics of convergent validity and discriminant validity derived from the analysis of structural equation modeling, the final instrument was composed of 59 items. The results reveal that hospital SSCM practices can be conceptualized and measured through two dimensions: environmental and social. The former includes the underlying constructs of internal environmental management, green purchasing and green operations. The latter encompasses the constructs of working conditions and employee well-being, equity management, social purchasing and community development and participation. Sustainable performance is defined by its environmental, social and economic dimensions.

This study is intended to provide useful insights for hospitals, researchers and policymakers to measure and develop strategies to enhance the implementation of SSCM practices, thereby improving sustainable performance. As a matter of fact, the instrument has already been applied in a recent empirical study conducted in Colombia, aimed at addressing the influence of SSCM practices on sustainable performance in hospitals.

To the best of the authors’ knowledge, this is the first study to develop and empirically test an instrument for measuring the influence of SSCM on sustainable performance, both in the hospital setting and in an emerging country.

This chapter takes a qualitative snapshot of rural entrepreneurs in Bulgaria. The aim is to shed light on the formation of non-farm start-up intentions in rural post-communism communities.

A qualitative ethnographical methodological approach centred on a theoretical framework, based on Ajzen’s (1991) Theory of Planned Behaviour. Primary survey data are drawn from the village of Kostandovo, in the Pazardjik region of Bulgaria.

A holistic perspective reveals entrepreneurship to be just one facet of complex rural livelihood strategies. Distrust in formal institutions by rural entrepreneurs dominates the Bulgarian business climate. A culture of informality in business is accompanied by widely accepted corruption. Crucial factors affecting the start-up decision in post-communist economies are social capital, a lack of experience of the entrepreneurs, and by public administrators.

The presented evidence highlights different dimensions of the theoretical constructs. Future research could focus on the impact of inefficient/corrupt institutions on the decisions of potential rural entrepreneurs.

By coupling universally applicable intention predicting theory with unique ethnographic evidence, the chapter gives a face of the otherwise abstract entrepreneurial agents. The perceptual perspective tackles the most relevant start-up aspects of the post-communist context, providing insights applicable beyond the case country.

The purpose of this paper is to provide empirical evidence on the relationships between the dimensions of intellectual capital (IC) and the generation of knowledge in public universities.

An online survey was developed and administered in Colombia. A total of 209 researchers participated in the study. Data were collected through IC measurements concerning the research mission of the universities. Scientific publications from the respondents and the citations received were taken as proxies for the generation of knowledge. To test the hypotheses, structural equation modeling was used.

Hypotheses proposing a positive association between the dimensions of IC, namely, human capital, structural capital, and relational capital, and the generation of knowledge were tested. The findings highlight that human capital is indirectly and positively related to the generation of knowledge through relational capital, as well as through the path of structural capital-relational capital.

The study suggests that directors of research at universities could improve the results of this activity by analyzing and understanding the dimensions of IC that contribute to the development of scientific capacities and the generation of knowledge.

This is one of the first studies that has examined the interrelationships between the dimensions of IC at universities and the generation of knowledge.

This chapter investigates how normative beliefs attributed to insecure paid work and care responsibilities affect social understandings of the work–family boundary, and either challenge or reinforce traditional links between gender and moral obligation.

Within an interpretive approach and from a gender perspective, I present a discourse analysis of 41 interviews with Italian parents.

This chapter shows that women in the sample felt forced into blurred boundaries that did not suit their work–family normative beliefs. Men in the sample perceived that they had more boundary control, and they created boundaries that support an innovative fatherhood model. Unlike women, men’s boundaries aligned with their desires.

The specific target of respondents prevents empirical comparisons between social classes. Moreover, the cross-level analysis presented is limited: in particular, further investigation is required at the level of organizational cultures.

The study suggests not only thinking in terms of work–family boundary segmentation and integration but also looking at the normative dimensions which can either enhance or exacerbate perceptions of the work–family interface. The value of the study also stems from its theoretically relevant target.

This chapter contains a case study analysis on a song by the Spanish heavy metal group Desafío or ‘Challenge’. The lyrics of the song are treated as a poem, and I will thus progress toward a linguistic and poetic analysis (Leech, 2013). Songs include many poetic devices, such as personification, metonymy, paradox, tautology, antithesis, and hyperbole (cf. Hewitt, 2000, p. 189). During the aforementioned linguistic and poetical analysis, it will be seen that the song Muerte en Mostar ‘Death in Mostar’ abounds with poetic features. The song begins with personification, for example: ‘The moon reflects in her face the shadows of evil’. Liturgical lexis and bellicose vocabulary also proliferate. Especially active in the song is the notion of an almost religious crusade. For example, one liturgical aspect found in the chorus is where an unnamed protagonist is described within the context of an almost holy war: ‘To his squadron's flag he promised his loyalty / His heart of love would be called by God’. The song goes on to recount the subsequent events and, therefore, this song in fact seems to be a mini-narrative. Finally, I will show how so much literary allusion reveals, in the end, that the song is not about Spain at all but about events that took place during the war of Bosnia–Herzegovina.

This paper aims to investigate the role of aripiprazole once monthly as a maintenance treatment in a sample of patients with schizophrenia comorbid with alcohol and substance use disorder (AUD/SUD).

A sample of 24 Italian adult patients has been recruited and treated with aripiprazole once monthly after clinical stabilization with oral aripiprazole during May 2021 and June 2022. Clinical evaluations have been performed at the baseline (T0) and after 12 (T1) and 24 (T2) weeks.

During the study period, an improvement of both the clinical condition and general health from baseline was observed, as well as a reduction of craving for alcohol/substances. However, from T0, the number of patients who continued with this study decreased at T1 (n = 8) and then at T2 (n = 4). No serious adverse events were reported, including changes in weight, lipid/glucose metabolism, electrocardiogram and extra-pyramidal side effects.

Although limited by the high number of drop outs, this observational real-world study provided insights into the use of aripiprazole once monthly among a sample of patients with schizophrenia and comorbid SUD/AUD. Further studies of longer duration and on a larger sample are needed.

The paper seeks to provide personalized learning objects to adults' educators of special groups (AESG) in a technology‐enhanced learning environment.

The paper presents a definition of specific criteria by which personalization of learning objects is effected. An analysis under the scope of adult education and multicultural education is performed, resulting in the development of tools and a clear path leading to more efficient personalization of learning objects of AESG within an e‐learning environment.

Personalization of learning objects for AESG can be achieved to a much greater extent when the element of compatibility between educator and learner defines content, preceding and mapping with presentation factors.

As the research is focused on AESG, the key notion of compatibility may not be applicable to adult educators of the general public.

The paper offers a path through which learning management systems can provide improved personalization of learning objects addressed to AESG.

The introduction of compatibility between educator and learner as the key element of the educator's profile in order to provide personalized learning objects addressed to AESG opens up new territory. The paper is also useful to the developers of learning management systems addressed to any group with special attributes which strongly affect the learner's profile.

The purpose of this paper is to find throughout history examples of wealth management of a family or business families that can be assimilated into the current concept of family offices (FOs). In such examples, the study identifies characteristics associated with the different dimensions of the concept of socioemotional wealth (SEW).

Drawing on the socioemotional perspective, this paper relates significant examples of FOs based on historical stages (ancient history, the middle ages, modern history, the contemporary period and the actual world). Each case is discussed with an effort to identify the dimensions of the SEW that fit and help in understanding the organization studied.

Mainly, FOs allow the management of the family legacy, philanthropy, promotion of entrepreneurship and family wealth preservation for future generations. Autonomy in decision-making, privacy and confidentiality and the achievement of more intangible goals make the FO preferable to other institutions. Through the study of historical cases, the FO constitutes a structure with objectives and activities that have remained consistent from Rome to the present, regardless of historical, political or social context. The results also identify four out of five FIBER dimensions of SEW.

In addition to contributing to the scarce literature on FOs, this paper uses various examples of historical periods to better understand its origin, evolution and current state. A selection of examples at different times allows us to verify that FOs undergo a series of changes throughout history but maintain their characteristics regardless of the historical context. This paper is the first to explore the origin and development of the FO as organization. Building on the findings, the authors present a conceptual SEW framework to deepen in the knowledge of FO. This framework could help researchers and practitioners in future researches providing a conceptual link that demonstrates the components of the SEW perspective best fit the objectives pursued by business families when establishing a family office.

Cycle tourism is considered as a trendy opportunity of local development that should be taken into consideration by several destinations to (further) increase tourism according to the sustainable development approach. It is a broad and complex phenomenon that involves various social and economic actors. Cycle tourists are looking for new and deep experiences to better benefit from the local identities and the uniqueness of the landscape of a territory. Cycle tourism gives sustainable access to environmental and cultural resources of territories often neglected. Despite its evident potentialities, the lack of studies represents a drawback that could compromise the local development. The aim of this chapter is first to describe the characteristics of this form of tourism both in terms of its contribution to the sustainable development and of demand and supply features. Second, the study focuses on an Italian area that is strongly investing in the development of this form of mobility: an area called “Insubria,” which is located in the Lombardy region, near the Swiss border and includes, as main cities, Varese and Como. The work explores whether the supply of the tourism product in this area is aligned with the current and future demand trends of cycling and tourism. The analysis ends with some suggestions about possible improvements in the area and for the long-term industry competitiveness.
