Abstract

In this paper a method is proposed for the determination of the correctable and detectable errors number, which ensures an optimum compromise between the incorrect decoding probability and the transmission rate. The method is based on the fact that by decreasing the correctable errors number and increasing the detectable errors number, both the incorrect decoding probability and transmission rate are reduced. Among the types of problems which can be solved by this method the most interesting is that of adapting the decoder to the transmission channel. In this paper the binary symmetrical channel is considered, but for other types of channels similar results can also be obtained.

Abstract

Purpose

The consumption of music performed in different languages represents a significant aspect of the contemporary cultural experience. This phenomenon questions how different languages mediate music consumption in specific national contexts. In this paper, the authors investigate the case of live music consumption in France.

Design/methodology/approach

The authors surveyed 428 persons who saw 159 artists either performing in French or in English in 46 locations around Paris, France. The authors tested the effect of the language of the concert on three dimensions of music consumption: singing in unison, appraisal of the lyrics and dancing.

Findings

Multilevel analysis revealed that English was positively associated with dancing, whereas French was positively associated with the appraisal of the lyrics. The authors found no evidence that the language of the concert was associated with differences in singing in unison.

Originality/value

Results are discussed with respect to language diversity in the context of globalised popular music consumption.

Abstract

A new decoding algorithm is deduced by dividing the set of all received words in non‐disjoint fuzzy sets instead of disjoint ordinary sets. This algorithm leads to quite simple decoders as regards the technical complexity, by choosing a convenient variation law for the received word's membership function. Moreover, this algorithm allows the decoder to adapt to the channel‐noise statistics in a certain sense. The algorithm may be used for both block and convolutional codes, but in this paper it is only applied to block codes, the following notations being used: k—information symbols number, n—word lengths, vi—code word, wj—received word.

Abstract

Purpose

This article aims at presenting the concept of the Brazilian university’s third mission and its relevance for predicting teaching behavior. To that end, this article presents a conceptual model of that third mission in Brazil and how its relationship with stakeholders was built.

Design/methodology/approach

This is a conceptual article. The authors analyze the third mission and the Brazilian educational model to suggest predicting teaching behavior as a possibility to optimize the third mission in higher education institutions.

Findings

The Brazilian third mission is related to civilian participation, John Dewey’s democratic education management, Paulo Freire’s transformative education, Triple-Helix and the knowledge ecology. This association enables insight into the relevance of the third mission and into the need for professors’ participation.

Practical implications

Revealing the factors of behavior prediction to perform the third mission is the first mission of the theory of planned behavior. Based on these data, the theory suggests interventions without changing teaching behavior. This possibility might increase the adherence of the professor to activities related to the third mission.

Originality/value

This article contributes to studies on the development of the third mission and to the sharing of a conceptual model that is partially different from the European model, thus promoting broader results for stakeholders. The indications made here can lead to empirical studies to further approximate the higher education institutions and the various sectors of society. Moreover, there is room for investigations that aim at a conceptual convergence at the international level for the third mission, as it happens for teaching and researching.

Abstract

Purpose

The research provides a systematic literature review on the environmental sustainability of the globe artichoke [Cynara cardunculus L. var. scolymus (L.) Fiori], in the cultivated cardoon [Cynara cardunculus L. var. altilis DC.] and in the wild cardoon [Cynara cardunculus L. var. sylvestris (Lamk)] supply chains, to fill in the literature data gaps and to identify new research directions.

Design/methodology/approach

In the light of the PRISMA standard guidelines, the research provides a systematic literature review according to six research strings on Scopus and Web of Science. 45 scientific articles have been selected out of 407 contributions. Data have been synthesized according to a co-word analysis through the VOSviewer software, to provide insights into the structure of the research network, to offer a multidimensional scaling and clustering into research groups and to discuss the results.

Findings

The research identifies five main research trends: (1) biomass-to-bioenergy or biomass-to-biocomposite materials; (2) waste-to-bioenergy or waste-to-bioproducts; (3) crop management to increase yield productivity; (4) environmental impacts assessment; (5) irrigation water management. Besides, the research highlights momentous challenges and adopted strategies to tackle climate change and to reduce natural resources consumption, as well as the nexus between circular economy and environmental impact assessment.

Originality/value

The novelty of this study relies on the fact that it analyses the environmental sustainability of the Cynara cardunculus L. spp. Supply chain in a systematic way, giving the opportunity to identify future research directions regarding the environmental impacts associated with agricultural production and industrial transformation.

Abstract

Purpose

The purpose of this paper is to investigate the manifestations and interactions at work between the ecological, environmental and social dimensions of sustainable development and the development of short food supply chains (SFSCs) in French fruit production.

Design/methodology/approach

The methodology is based on the theoretical framework associated with SFSCs and each pillar of sustainability. The authors use an original database of 176 surveys of peach and apricot producers from the major French production regions. Three composite indicators, one for each traditional pillar of sustainability, are calculated to evaluate a degree of sustainability at farm level. A simultaneous equations model is estimated on the basis of the calculated indicators.

Findings

The results show that in the choice of a supply chain design in the agricultural sector, the search for economic sustainability is opposed to a rationale of environmental and social sustainability, the latter appearing to be independent of one another.

Originality/value

This paper complements the previous studies on the issue of sustainability in agriculture and more specifically the relationship between the adoption of SFSCs and the pillars of sustainable development. The model reveals significant interdependencies, thus emphasizing an issue in reconciling economic imperatives with social or environmental requirements.

Abstract

Purpose

Adopting Mapping Literature, the purpose of this study is to notice the tendency in defining contextualism through extrinsic aspects neglecting the intrinsic ones generating three theoretical gaps in understanding contextualism, especially in terms of (1) physical/cultural aspects (P/C); (2) traditional vs contemporary architecture (T/C); and (3) place identity (PI).

Design/methodology/approach

A directed systematic literature review (SLR) was conducted to investigate the Web of Science and Google Scholar engines for the related studies, resulting in 66 texts of book chapters, conferences, articles and practitioners’ texts. Using the PRISMA reporting method, the study presented the SLR procedure that narrowed the related studies to 66 texts of book chapters, conferences, articles and practitioners’ texts. Both consensus and debates in understanding the relation between contextualism and (T/C, P/C and PI) were re-visited (see Appendix).

Findings

According to the findings, the studies tend to address contextualism through either extrinsic or intrinsic values. The undefined balance between extrinsic and intrinsic aspects in understanding and creating contextual architecture seems to be the common reason why the three theoretical gaps exist.

Originality/value

This paper did not only conduct an SLR investigation on the topic, which is limited in the field, but it also highlighted the need for further and constant discussions despite the previous one to improve the understanding of contextual architecture.

Abstract

Purpose

It has been widely recognised that the participation of residents is a significant issue in contemporary urban heritage conservation. However, studies confirm that the reasons behind residents' engagement are still difficult to assess, particularly in emerging countries. This paper aims to evaluate the factors that incite or prevent residents from participating in built heritage rehabilitation in the old city of Constantine, by applying the motivation-opportunity-ability (MOA) model.

Design/methodology/approach

A questionnaire-based survey was used to collect information from the residents. The collected data were then analysed using the structural equation model (SEM).

Findings

The findings show that the most significant factors affecting residents' participation were related to their motivations and abilities. Interestingly, factors related to the opportunities did not influence participation. Thus, autonomous rehabilitation according to the residents' motivation and abilities is more likely to be adopted.

Research limitations/implications

These findings are limited to the selected sample, and some variables have been eliminated through the SEM analysis.

Originality/value

However, as a first attempt to study residents' participation in built heritage rehabilitation in Constantine, the paper proposes a different perspective for assessing participation by considering its means and ends simultaneously. The paper also provides guidance to local decision-makers to improve the legal framework by implementing factors that encourage residents' involvement in sustainable heritage management.

Abstract

Purpose

This work critiques the situation of the ecological and cultural heritage in many coastal territories and analyses how current land planning methodologies are responding to it. The study builds a new integrated approach founded on ecocultural values and local knowledge as resources for an effective territorial planning and sustainable development.

Design/methodology/approach

The proposed framework was developed through: (1) analysing coastal planning needs and problems in European coastal areas; (2) identifying ecocultural values, including local knowledge, in such areas; (3) selecting best approaches and tools in spatial planning; (4) applying the selected planning approaches to use ecocultural values as resources for spatial planning and sustainable development; and (5) validating the final methodology.

Findings

A dynamic approach for maritime-land planning was developed projecting coastal waters and river basins as strategic drivers for sustainable development, based on the natural capacity of water to shape and integrate the ecological and cultural territory. A participatory governance planning methodology supports the new articulations of space based on ecocultural value chains and networks as synergistic vectors, focusing on local knowledge as psychosocial capital for a collective mapping of cultural, historical, social, economic and ecological values into ecocultural littoral plans.

Originality/value

The results show the potentials of combining new approaches applying cultural and ecological heritage into an effective strategy of integration between society and territory as a powerful driver for effective sustainable planning and development.

Abstract

Purpose

The purpose of this paper is to examine the relationship between import and economic growth for 62 countries.

Design/methodology/approach

The paper applies autoregressive distributed lag model (ARDL) for long‐run relation and Granger causality test, in order to detect the direction of short‐run and long‐run causal relationship.

Findings

The results indicate that the long‐run relationship exists in the USA, the UK, Japan, Iceland, Canada, Italy, Algeria, Brazil, Chile, Colombia, Cuba, Gabon, Malaysia, Mexico, Peru, South Africa, Uruguay, Bolivia, Cameroon, Cote d'Ivoire, Ecuador, Egypt, El Salvador, Guatemala, Honduras, India, Lesotho, Nicaragua, Papua New Guinea, Thailand, Bangladesh, Benin, Chad, Congo, Gambia, Kenya, Madagascar, Togo, Zambia and Zimbabwe when economic growth is dependent variable. This result confirms the importance of import in the process of sustainable economic growth of these countries. In alternative combination when import is dependent variable, the long‐run relationship is found in the USA, the UK, Japan, Finland, Iceland, Canada, Italy, Brazil, Cuba, Dominican Republic, Iran, Malaysia, Mexico, Peru, South Africa, Bolivia, Cameroon, Guatemala, Honduras, India, Indonesia, Lesotho, Morocco, Nicaragua, Pakistan, Philippines, Senegal, Sudan, Swaziland, Thailand, Tunisia, Bangladesh, Benin, Burkina Faso, Chad, Congo, Gambia, Kenya, Madagascar, Malawi, Mali, Mauritania, Togo and Zambia. These findings confirm the importance of source of economic growth for import. On the other hand, the results of Granger causality test indicate mixed results but the importance is that in the case of higher income countries, there is unidirectional long‐run causality found from import to economic growth (except the USA, Iceland and Italy), and bidirectional long‐run causal relationship exists between import and economic growth in low income countries except Madagascar and Mauritania.

Originality/value

This paper provides the largest sample, including 62 countries, examining the relationship between import and economic growth, from 1971 to 2009.
