Abstract

Purpose

The partially prestressed concrete beam with unbonded tendon is still an active field of research because of the difficulty in analyzing and understanding its behavior. The finite-element (FE) simulation of such beams using numerical software is very scarce in the literature and therefore this study is taken to demonstrate the modeling aspects of unbonded partially prestressed concrete (UPPSC) beams. This study aims to present the three-dimensional (3-D) nonlinear FE simulations of UPPSC beams subjected to monotonic static loadings using the numerical analysis package ANSYS.

Design/methodology/approach

The sensitivity study is carried out with three different mesh densities to obtain the optimum elements that reflect on the load–deflection behavior of numerical models, and the model with optimum element density is used further to model all the UPPSC beams in this study. Three half-symmetry FE model is constructed in ANSYS parametric design language domain with proper boundary conditions at the symmetry plane and support to achieve the same response as that of the full-scale experimental beam available in the literature. The linear and nonlinear material behavior of prestressing tendon and conventional steel reinforcements, concrete and anchorage and loading plates are modeled using link180, solid65 and solid185 elements, respectively. The Newton–Raphson iteration method is used to solve the nonlinear solution of the FE models.

Findings

The evolution of concrete cracking at critical loadings, yielding of nonprestressed steel reinforcements, stress increment in the prestressing tendon, stresses in concrete elements and the complete load–deflection behavior of the UPPSC beams are well predicted by the proposed FE model. The maximum discrepancy of ultimate moments and deflections of the validated FE models exhibit 13% and −5%, respectively, in comparison with the experimental results.

Practical implications

The FE analysis of UPPSC beams is done using ANSYS software, which is a versatile tool in contrast to the experimental testing to study the stress increments in the unbonded tendons and assess the complete nonlinear response of partially prestressed concrete beams. The validated numerical model and the techniques presented in this study can be readily used to explore the parametric analysis of UPPSC beams.

Originality/value

The developed model is capable of predicting the strength and nonlinear behavior of UPPSC beams with reasonable accuracy. The load–deflection plot captured by the FE model is corroborated with the experimental data existing in the literature and the FE results exhibit good agreement against the experimentally tested beams, which expresses the practicability of using FE analysis for the nonlinear response of UPPSC beams using ANSYS software.

Abstract

Purpose

High rates of suicide and self-harm are reported in prisons in Western countries, while fewer studies exist from a non-Western context. This study aims to identify rates of suicide, non-fatal suicide attempts and self-harm in Moroccan prisons and to better understand the context, methods, tools, predictors and profile of persons engaged in the acts.

Design/methodology/approach

The authors report findings from a mixed-methods study carried out before an intervention project. The study consists of a systematic literature review, an analysis of suicide case files, a quantitative survey on suicide attempts and self-harm, as well as interviews and focus group discussions. The authors calculate suicide, suicide attempt and self-harm rates and present descriptive data on the incidents. The authors use regression models to explore the association between the number of incidents per individual and selected predictors, adjusting for clustering by institution.

Findings

Over a four-year period, 29 detained persons in Morocco died by suicide (average annual suicide rate 8.7 per 100,000). Most were men under the age of 30. Hanging accounted for all but one case. In one year, 230 suicide attempts were reported. Over a three-months period, 110 self-harm cases were reported from 18 institutions, cutting being the most common method. Self-harm was significantly more prevalent among persons with a life sentence or repeated incarcerations.

Research limitations/implications

To make the study manageable as part of an intervention project, the authors collected data on suicides and suicide attempts from all prisons, while data on self-harm were collected from fewer prisons and over a shorter time period. The authors did not collect comparable information from detained persons who did not die by suicide, attempt suicide or self-harm. This prevented comparative analyses. Further, it is possible that self-harm cases were not reported if they did not result in serious physical injury. Data were collected by prison staff; thus, the voice of incarcerated persons is absent.

Practical implications

This study provided a solid basis for designing an intervention project including the development of a national prison policy and guidelines on suicides, suicide attempts and self-harm and a country-wide training program for prison staff. It also led to a better surveillance system, allowing for trend analysis and better-informed policymaking. The qualitative results helped create an understanding of how staff may trivialize self-harm. This was integrated into the training package for staff, resulting in the creation of prison staff trainers who became the strongest advocates against the notion that self-harm was best ignored.

Originality/value

To the best of the authors’ knowledge, this is the first published data on suicide and self-harm in Moroccan prisons. It underscores the necessity for the intervention project and gives valuable insights into suicide and self-harm in a non-Western prison context. Further research is needed to assess whether the findings are typical of the region.

Abstract

Purpose

This study aims to determine the effect of replacing a portion of the cement in the concrete mixture with silica fume (SF) on the corrosion resistance of reinforcing bars, the compressive strength of concrete and the tensile strength of hook bars in both corroded and non-corroded external joints of structures. The external beam-column connection was studied because of its critical role in maintaining structural continuity in all three directions and providing resistance to rotation.

Design/methodology/approach

In external concrete joints, the bars at the end of the beams are often bent at 90° to form hooks that embed in columns. Owing to the importance of embedding distance and the need to understand its susceptibility to corrosion damage from chloride attack, a series of experiments were conducted on 12 specimens that accurately simulate real-site conditions in terms of dimensions, reinforcement and hook bars. SF was replaced with 10% and 15% of the weight of cement in the concrete mixture. To simulate corrosion, the specimens were subjected to accelerated corrosion in the laboratory by applying a low continuous current of 0.35 mA for 58 days.

Findings

The results revealed the effect of SF in improving the compressive strength of concrete, the pullout resistance of the hook bars and the corrosion resistance. In addition, it showed an apparent effect of the corrosion of reinforcing bars in reducing the bonding strength of hook bars with concrete and the effect of SF in improving this strength.

Originality/value

It was noted that the improvement of the results, achieved by replacing 10% of the weight of cement with SF, was significantly close to the results obtained by replacing 15% of the SF. It is recommended that an SF ratio of 10% be adopted to achieve the greatest economic savings.

Abstract

Purpose

This paper aims to analyze the “crafts” of governance within social and solidarity economy (SSE) cultural organizations, considering formal and informal rules, to support their project of democratization of arts and culture and more generally of cultural democracy. The hypothesis is that it is through participatory and democratic governance that SSE can have a transformative role.

Design/methodology/approach

This paper builds upon a qualitative, multiple case study of three SSE organizations in the performing arts and audiovisual production in France. Although different in age, size and legal form, they all experiment a more participative governance system, not without tensions, to face deep institutional changes in their environment.

Findings

The results show that legal forms from the SSE are necessary safeguards but not sufficient to effectively implement a democratic governance beyond the “one member, one vote” principle. Democratic governance is supported by both formal and informal rules. By experimenting with innovative participative and democratic governance rules, these organizations contribute to the transformation of practices in the cultural field (democratization of art and culture) but also in society at large by fostering cultural democracy.

Research limitations/implications

Building upon three case studies, this exploratory work stresses important issues that are worth to explore on a larger scale to understand by which levers SSE can play a transformative role in the cultural field.

Originality/value

This paper contributes to the literature on SSE and on governance by enlarging the analysis beyond the board of directors and the statutory rules. Applying the approach of collective action and reasonable values developed by Commons to SSE, it shows that participatory governance cannot be based on an ideal or a choice of preestablished values and principles but must leave room for creativity and representations of stakeholders not only to support transformation of practices within the cultural field but also externally by increasing cultural democracy.

Abstract

Purpose

The purpose of this study is shed light on the underlying forces behind entrepreneurship within a regional innovation system (RIS) in a remote rural region. The authors examine the following questions: Which are the main underlying forces behind the entrepreneurial process in a rural RIS characterized by traditionally low-tech, small-scale businesses? How can the development of a low-tech regional innovation system be conceptualized?

Design/methodology/approach

The design of the study is based on entrepreneurship theory. Data analysis followed practices used in phenomenography, a research approach used to analyse and identify commonalities and variations in populations' perceptions of a certain phenomenon. Data are composed using semi-structured interviews and a database composed of company information of all firms in the population.

Findings

A proactive mobilization of regional stakeholders and resources can be an important driving force behind the entrepreneurial process and generation of a rural RIS. Innovation can be generated within low-tech industries turning the rural context into an asset. An RIS in a remote rural context can be initiated and orchestrated by regional authorities, but knowledge brokering and orchestration can also be managed by networks of small-scale businesses brought together by mutual benefit and common interests.

Research limitations/implications

Regional innovation systems theory is most often used to study high-tech industries. But by combining regional innovation systems with rural entrepreneurship and entrepreneurship context theory is a fruitful avenue to understand the role of rural entrepreneurship in regional development, even in remote and peripheral regions. Innovation does not need to entail high-tech international environments; it can appear as the result of efforts in low-tech industries in rural and remote environments. The authors’ findings need to be scrutinized; therefore, the authors call for more research on regional innovation systems in rural environments.

Practical implications

It is possible for regional authorities to orchestrate a development process through the actions of a strong regional agent but also by supporting the creation of networks of small businesses that are built on trust and common interests.

Originality/value

This study contributes to the literature with a new perspective to the study of entrepreneurship and of regional innovation systems. Entrepreneurship research with focus on rural contexts most often highlight limits to entrepreneurship and see entrepreneurship as “just running a business”. A perspective that starts from innovation and innovative behaviour, despite the rural context and embedded resources, helps to generate new knowledge that can enrich the understanding of entrepreneurship and also be the foundation for more precise business development policies in rural settings.

Abstract

Purpose

This article aims to explore how cluster affiliation moderates the relationship between family involvement and speed of internationalization in family firms. The speed of internationalization is examined in terms of earliness and post-internationalization speed.

Design/methodology/approach

The research is based on a sample of 639 Portuguese family businesses (FBs) created and internationalized between 2010 and 2018 that was retrieved from the Iberian Balance Analysis System – SABI database. The partial least squares structural equation modeling (PLS-SEM) was used to assess the measurement and construct the model.

Findings

The results suggest that higher levels of family involvement in ownership and management make family firms enter on international markets in later stages of their development but, after the first international market entry, the firms are able to exhibit a higher post-internationalization speed. When considering the effect of cluster affiliation, the authors found that clustered FBs are more likely to engage in early internationalization and to accelerate the post-internationalization process than non-clustered FBs.

Originality/value

The study's findings are explained by the existence of socially proximate relationships with other cluster members, based on similarity, trust, knowledge exchange and sense of belonging, which push family firms to internationalize and increase their level of international commitment over time. The empirical evidence, therefore, highlights the primary role of industrial clusters in moderating the relationship between family involvement, earliness of internationalization and post-internationalization speed.

Abstract

Purpose

This paper aims to investigate how emerging market multinational enterprises (EMNEs) are integrating and expanding into other emerging market host countries, focusing on Chinese mining companies in Peru.

Design/methodology/approach

Adopting a qualitative approach, an in-depth analysis of two Chinese state-owned enterprises’ strategies was conducted, building on stakeholder theory and the business ecosystem perspective.

Findings

This study reveals a reliance on high-level political lobbying rather than localized engagement strategies. However, findings point to increasing grassroots resistance among local stakeholders, undermining EMNEs’ bargaining power.

Originality/value

This paper argues for a paradigm shift toward inclusive, cooperative “translocal governance” approaches as empowered communities gain voice. Key contributions include advancing theoretical understanding of changing stakeholder relationships and power configurations in emerging countries, underscoring the rising significance of microlevel sociocultural embeddedness for MNE success and highlighting practical imperatives for EMNEs to embark on rapid localization strategies in Latin America. By elucidating multilayered integration realities in Peru, this interdisciplinary study yields contextualized insights and enriches perspective on the conditions and pathways for EMNEs to build sustainability in Global South emerging market environments.

Abstract

Purpose

This paper covers the development of a novel defect model for concrete highway bridges. The proposed defect model is intended to facilitate the identification of bridge’s condition information (i.e. defects), improve the efficiency and accuracy of bridge inspections by supporting practitioners and even machines with digitalised expert knowledge, and ultimately automate the process.

Design/methodology/approach

The research design consists of three major phases so as to (1) categorise common defect with regard to physical entities (i.e. bridge element), (2) establish internal relationships among those defects and (3) relate defects to their properties and potential causes. A mixed-method research approach, which includes a comprehensive literature review, focus groups and case studies, was employed to develop and validate the proposed defect model.

Findings

The data collected through the literature and focus groups were analysed and knowledge were extracted to form the novel defect model. The defect model was then validated and further calibrated through case study. Inspection reports of nearly 300 bridges in China were collected and analysed. The study uncovered the relationships between defects and a variety of inspection-related elements and represented in the form of an accessible, digitalised and user-friendly knowledge model.

Originality/value

The contribution of this paper is the development of a defect model that can assist inexperienced practitioners and even machines in the near future to conduct inspection tasks. For one, the proposed defect model can standardise the data collection process of bridge inspection, including the identification of defects and documentation of their vital properties, paving the path for the automation in subsequent stages (e.g. condition evaluation). For another, by retrieving rich experience and expert knowledge which have long been reserved and inherited in the industrial sector, the inspection efficiency and accuracy can be considerably improved.

Abstract

Purpose

The paper aims to understand why and how paratextual elements are included in annual reports, hence how meaning is made through the workings of language and imagery.

Design/methodology/approach

A comprehensive framework of analysis, combining Genette’s paratextual elements with Barthes’ rhetoric and denotation and connotation concepts, is applied to the case study of the dstgroup, a Portuguese engineering and construction group.

Findings

The study demonstrates the potential of the annual report as a communication tool between an organisation and its stakeholders. The framework of analysis evidences that the paratextual elements highlight and supplement accounting information and that the denotative and connotative meanings associated with them make visible and enhance intangible features of the organisation.

Originality/value

The paper extends theories from other interdisciplinary fields to accounting communication and proposes a comprehensive framework that combines the writings of Genette and Barthes. By exploring the Portuguese under-researched context, it also adds to the literature by analysing the rationales and choices of the preparers on the inclusion of paratextual elements in annual reports.

Propósito

Este artículo pretende entender por qué y cómo se incluyen elementos paratextuales en los informes anuales y, cómo se construye el significado a través del funcionamiento del lenguaje y las imágenes.

Diseño/metodología/enfoque

Se desenvolvió un marco de análisis global, que combina los elementos paratextuales de Genette y los conceptos de retórica y denotación y connotación de Barthes. Este marco se aplicó al estudio de caso del grupo dst, un grupo portugués de ingeniería y construcción.

Resultados

El estudio muestra el potential del informe anual como herramienta de comunicación entre una organización y sus grupos de interés. El marco de análisis evidencia que los elementos paratextuales resaltan y complementan la información contable y que los significados denotativos y connotativos asociados a ellos hacen visibles y realzan rasgos intangibles de la organización.

Originalidad/valor

Este artículo extiende teorías de otros campos interdisciplinarios a la comunicación contable y propone un marco global que combina los escritos de Genette y Barthes. Explorando el contexto portugués, insuficientemente investigado, también se añade a la literatura mediante el análisis de las motivaciones y opciones de los preparadores de los informes anuales sobre la inclusión de elementos paratextuales.

Abstract

Purpose

The concept of “participation” has become a buzzword in contemporary public governance models. However, despite the broad and significant interest, defining participation remains a debated topic. The aim of the current study was to explore how participants perceived and interpreted the meaning and scope of participation.

Design/methodology/approach

This study is part of a four-year (2019–2022) longitudinal research project investigating stakeholder participation in the context of developing and establishing a strategic regional plan in Region Skåne in southern Sweden. The research project has a qualitative approach and uses interviews with different stakeholder groups such as municipal politicians and public officials and a survey as empirical material.

Findings

The authors developed a participation spectrum including eight types of participation: to be open, to be informed, to be listened to, to discuss, to be consulted, to give and take, to collaborate and to co-create. The authors also identified four different purposes of participation: creating a joint network, creating a joint understanding, creating a joint effort and creating a joint vision. The spectrum and the purposes were related through four characteristics of participation, i.e. involvement, interaction, influence and empowerment.

Research limitations/implications

The study rests on a single case, and so the results have limited transferatibility.

Originality/value

Researching participation in terms of the participants' perceptions contributes a new perspective to the existing literature, which has commonly focussed on the organizers' perceptions of participation. Moreover, in order to clarify what participation meant to the participants, the study puts emphasis on untangling this from the why question of participation.
