Abstract

A contribution to the definition of a novel safety format for the design of concrete structures based on non‐linear methods of analysis is the main purpose of this work. A brief discussion of design formats proposed by codes of practice is introduced. Probabilistic analyses of current concrete frames are performed and the corresponding results are used as a basis to derive simplified and coherent practical rules. The analyses have been carried out taking into account the non‐linear material behaviour and the variability of the structural parameters by simulation of probabilistic density functions. A simple procedure is proposed to evaluate the structural safety of concrete frame structures. Mean values are recommended to characterise the material properties to be used in the analysis and a global safety factor is defined to evaluate the structural design resistance.

Abstract

Purpose

The present study aims to analyze the influence of stress, job satisfaction and work–life balance on auditors’ job performance and examine the moderating effect of telework on previous relationships.

Design/methodology/approach

The research data are collected through an electronic questionnaire with 322 Portuguese auditors. We used a partial least squares–structural equation model and fuzzy set quality comparative analysis to test our hypotheses.

Findings

There is a positive relationship between job satisfaction and job performance. Conflict, positively, and ambiguity, negatively (components of stress), influence job performance. Work–family conflict was shown to be equally impactful in decreasing auditors’ technical knowledge and ability, and this effect was amplified in the presence of telework. The results show the existence of a complex structure of configurational arrangements that are sufficient to achieve high job performance.

Practical implications

Audit firms need to pay attention to employees’ feelings related to their work since their well-being affects their job performance. In general, the teleworking context did not affect the relationships studied, which means that audit firms can enjoy its advantages without compromising audit quality.

Originality/value

The study contributes to the growing literature on the determinants of auditor performance. The inclusion of teleworking as a contingent factor is a theoretical innovation in auditing studies. The results emphasize the importance of researchers including the multi-method approach for a better understanding of the complex structure of configurations that are sufficient for job performance.

Abstract

Purpose

In the macroeconomic environment of the Iberian Peninsula, this paper aims to understand which factors, intrinsic to management, affect the performance of wine companies.

Design/methodology/approach

The sample comprises 3,113 wine Iberian companies between 2011 and 2018. This study has used the panel data methodology, specifically the generalized method of moments system estimation method of Arellano and Bond (1991); Arellano and Bover (1995); and Blundell and Bond (1998) to test the hypotheses proposed.

Findings

Using return on assets (ROA) and sales growth as measures of corporate performance, this study’s results suggest that sales growth is the variable that has the most significant determining factors, both specific to the company and given the macroeconomic environment. Investors and civil society well understand the meaning of sales growth, namely, in a sector close to the final consumer. When using ROA as a dependent variable, the results suggest that because it is a pure management variable, the manager tends to be more concerned with maintaining adequate levels of economic profitability to ensure sustainability and future solvency, without giving prominence to the macroeconomic environment.

Originality/value

To the best of the authors’ knowledge, this is the first time that a study has been carried out in the Iberian Peninsula on the wine industry using ROA and sales growth as measures of corporate performance. This study shows that sales growth is a measure traditionally known to external stakeholders, and to that extent, its determining factors are the variables that these players most value in the market.

Abstract

Purpose

The purpose of this paper is to analyze the innovation process of organizations representing the main sectors of Brazilian economic activity.

Design/methodology/approach

The literature review focuses on analyzing the innovation process characteristics regarding the innovation types. The authors carried out interviews with executives and managers in charge of innovation at the leading large companies in the respective sectors analyzed. The data analysis of this qualitative research was structured in three steps. The first step is the analysis of data collected for encoding, the second step, the summarization of the common points presented by the companies in each sector and, finally, the interpretation of these data, aided by triangulation from secondary data that support the analysis of the collected primary data.

Findings

The main contribution of this study is to characterize the innovation process of organizations representing the main sectors of the Brazilian economy, with a classification regarding the sectoral innovation standard.

Practical implications

The authors’ intent is that the paper can contribute with a comparative analysis among companies of the same sector and, subsequently, among companies of the different surveyed sectors. Thus, the characterization aims to present the companies’ innovation process and the comparative analysis aims to verify the innovation sectoral patterns. In addition, as implications for management practice, some strategies for better knowledge management in the organization are suggested for each type of innovation.

Originality/value

The main theoretical contribution focuses on the development of a conceptual model that structures the analyzed variables of the constructs “innovation process” and “innovation sectoral patterns”, allowing not only the characterization but also the comparative analysis of the representative organizations present in the sample.

Abstract

Purpose

The purpose of this research paper is to present a pragmatic and systematic approach to conduct and document Design Science Research (DSR) activities with Focus Groups (FGs), exploring its continuous usage and providing traceability between problem, requirements, solutions and artefacts.

Design/methodology/approach

The approach is to conduct the research and produce the meta-model for DSR with FG, a DSR approach was adopted using a conceptual model for Action Design Research already available. The artefact is the result from a specific literature review to define requirements, a careful design and a refinement stage where it was widely used and tested in real IS implementation projects.

Findings

Rigorous and committed stakeholder engagement is a critical success factor in complex projects. The main outcome of this research is a specific meta-model for DSR with FG that delivers new insights and practical guidelines for academics and professionals conducting and documenting real-world research and development initiatives deep-rooted in stakeholders' participation.

Research limitations/implications

The meta-model has been endorsed as a practical and useful artefact by the stakeholders participating in the IS projects where it was adopted. However, to fully demonstrate its capabilities and to become more robust, the model has to be further used and tested in other application situations and environments.

Originality/value

The usage of FGs in DSR has already been proposed as an effective way, either to study artefacts, to propose improvements in its design or to acknowledge the utility of those artefacts in field use. The paper provides a sound contribution to this line of research by presenting a meta-model that integrates process and data, as well as a set of practical templates and forms that may be used by researchers and practitioners to conduct their projects.

Abstract

Purpose

Enterprise knowledge graphs (EKG) in resource description framework (RDF) consolidate and semantically integrate heterogeneous data sources into a comprehensive dataspace. However, to make an external relational data source accessible through an EKG, an RDF view of the underlying relational database, called an RDB2RDF view, must be created. The RDB2RDF view should be materialized in situations where live access to the data source is not possible, or the data source imposes restrictions on the type of query forms and the number of results. In this case, a mechanism for maintaining the materialized view data up-to-date is also required. The purpose of this paper is to address the problem of the efficient maintenance of externally materialized RDB2RDF views.

Design/methodology/approach

This paper proposes a formal framework for the incremental maintenance of externally materialized RDB2RDF views, in which the server computes and publishes changesets, indicating the difference between the two states of the view. The EKG system can then download the changesets and synchronize the externally materialized view. The changesets are computed based solely on the update and the source database state and require no access to the content of the view.

Findings

The central result of this paper shows that changesets computed according to the formal framework correctly maintain the externally materialized RDB2RDF view. The experiments indicate that the proposed strategy supports live synchronization of large RDB2RDF views and that the time taken to compute the changesets with the proposed approach was almost three orders of magnitude smaller than partial rematerialization and three orders of magnitude smaller than full rematerialization.

Originality/value

The main idea that differentiates the proposed approach from previous work on incremental view maintenance is to explore the object-preserving property of typical RDB2RDF views so that the solution can deal with views with duplicates. The algorithms for the incremental maintenance of relational views with duplicates published in the literature require querying the materialized view data to precisely compute the changesets. By contrast, the approach proposed in this paper requires no access to view data. This is important when the view is maintained externally, because accessing a remote data source may be too slow.

Abstract

Purpose

This work aims to identify the linear elastic orthotropic material paramters of Pinus pinaster Ait. wood, using full-field measurements and an inverse identification strategy based on the finite element (FE) method updating technique.

Design/methodology/approach

Compression tests are carried out under uniaxial and quasi-static loading conditions on wood specimens oriented on the radial-tangential (RT) plane, with different grain orientations. Full-field displacements and strains are measured using digital image correlation (DIC), which are then used as a reference in the identification procedure. A FE model is implemented assuming plane stress conditions, where wood is modelled as an orthotropic homogeneous material. Based on the numerical results, a synthetic image reconstruction scheme is implemented to synthetically deform the reference experimental image, which is then processed by DIC and further compared to the experimental results.

Findings

The results for both approaches were similar when both specimen configurations were used in a single run. However, when using the DIC-based FEMU approach with the on-axis configuration, the identified modulus of elasticity in the tangential direction and shear modulus are closer to the reference values.

Originality/value

This approach ensures a fair comparison between both sets of data since the full-field strain maps are obtained through the same filter and therefore have the same strain formulation, spatial resolution and data filtering. Firstly, the identification is performed using a single configuration, either the on-axis or the off-axis specimen. Secondly, the identification is carried out by merging data from both on-axis and off-axis configurations.

Abstract

This chapter examines the professional identities of Brazilian journalists. It does so through an analysis of the growing professional autonomy of journalism from 1950 to 1990 through the life stories of 10 intellectual-journalists, individuals whose journalistic activities have crossed over into other intellectual fields.

This study applies a symbolic interactionist framework to understand how these actors managed their reputations and careers within the intellectual world. The narratives were taken from qualitative semi-structured interviews, and supported by additional research such as interviews, biographies, and articles which have been published about their lives.

The life stories were compared to the extensive structural changes affecting the world of journalism and the world of intellectuals in Brazil. This comparison revealed gaps between these two spheres of practice, within which the ambivalent form of journalists’ identities have been constructed.

This chapter offers two contributions to the study of Brazilian journalists. From a theoretical and methodological viewpoint, it advances beyond other studies that focus more on the prevailing representations of journalists’ professional identities and their role in society. From an empirical standpoint, it describes the complex negotiations between the worlds of journalism, culture and politics. This chapter also reexamines the current dominant explanation for the changes in Brazilian journalism. It shows that building careers and new levels of interpersonal cooperation for intellectuals and journalists has been a slow process. Ultimately, this development has left some behind, especially those actors stretched between multiple professional identities such as those who self-identify as intellectual-journalists.

Abstract

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract

Purpose

The purpose of this paper is to test whether training correctional facility (CF) officers in the admission process would identify risk factors for inmates’ unscheduled transfers to healthcare units in the first 24 hours.

Design/methodology/approach

Correctional officers (COs) were trained to use a questionnaire with ten closed questions, which seeks to identify occupational or nosocomial risk, applied upon the admission of inmates to a CF.

Findings

There were 1,288 admissions in six CFs in Ribeirão Preto and Serra Azul/Brazil from March 2010 to May 2011. Of those admissions, 21.2 percent were in penitentiaries and 78.9 percent in provisional detention centers. Of the questionnaires applied, 580 answered affirmatively (45 percent) for one or more of the questions, with nearly 60 percent related to drug use in the last 12 hours, 37.7 percent use of medications while the most frequently mentioned diseases were respiratory diseases (37 percent) and mental disorders (19 percent).The number of positive responses per evaluation presented an odds ratio of 3.6 (CI 95% – 1.6, 10.5) for unscheduled transfers for external clinical evaluation.

Research limitations/implications

The lack of a control group and the fact that morbidities described by prisoners could not be confirmed are study limitations. The research does, however, still contribute to the goal of achieving appropriate medical care within CFs.

Originality/value

The training of COs to identify risk factors that predict the need for unplanned transfers to healthcare units was feasible. These findings have important implications for CFs that do not provide ongoing medical service, a universal reality in Brazil.
