Abstract
Purpose
To overcome the limitations of purely statistical approaches to data protection, the purpose of this paper is to propose Semantic Disclosure Control (SeDC): an inherently semantic privacy protection paradigm that, by relying on state of the art semantic technologies, rethinks privacy and data protection in terms of the meaning of the data.
Design/methodology/approach
The need for data protection mechanisms able to manage data from a semantic perspective is discussed and the limitations of statistical approaches are highlighted. Then, SeDC is presented by detailing how it can be enforced to detect and protect sensitive data.
Findings
So far, data privacy has been tackled from a statistical perspective; that is, available solutions focus just on the distribution of the data values. This contrasts with the semantic way by which humans understand and manage (sensitive) data. As a result, current solutions present limitations both in preventing disclosure risks and in preserving the semantics (utility) of the protected data.
Practical implications
SeDC captures more general, realistic and intuitive notions of privacy and information disclosure than purely statistical methods. As a result, it is better suited to protect heterogenous and unstructured data, which are the most common in current data release scenarios. Moreover, SeDC preserves the semantics of the protected data better than statistical approaches, which is crucial when using protected data for research.
Social implications
Individuals are increasingly aware of the privacy threats that the uncontrolled collection and exploitation of their personal data may produce. In this respect, SeDC offers an intuitive notion of privacy protection that users can easily understand. It also naturally captures the (non-quantitative) privacy notions stated in current legislations on personal data protection.
Originality/value
On the contrary to statistical approaches to data protection, SeDC assesses disclosure risks and enforces data protection from a semantic perspective. As a result, it offers more general, intuitive, robust and utility-preserving protection of data, regardless their type and structure.

Abstract
Purpose
The purpose of this paper is to propose a privacy-preserving paradigm for open data sharing based on the following foundations: subjects have unique privacy requirements; personal data are usually published incrementally in different sources; and privacy has a time-dependent element.
Design/methodology/approach
This study first discusses the privacy threats related to open data sharing. Next, these threats are tackled by proposing a new privacy-preserving paradigm. The main challenges related to the enforcement of the paradigm are discussed, and some suitable solutions are identified.
Findings
Classic privacy-preserving mechanisms are ineffective against observers constantly monitoring and aggregating pieces of personal data released through the internet. Moreover, these methods do not consider individual privacy needs.
Research limitations/implications
This study characterizes the challenges to the tackled by a new paradigm and identifies some promising works, but further research proposing specific technical solutions is suggested.
Practical implications
This work provides a natural solution to dynamic and heterogeneous open data sharing scenarios that require user-controlled personalized privacy protection.
Social implications
There is an increasing social understanding of the privacy threats that the uncontrolled collection and exploitation of personal data may produce. The new paradigm allows subjects to be aware of the risks inherent to their data and to control their release.
Originality/value
Contrary to classic data protection mechanisms, the new proposal centers privacy protection on the individuals, and considers the privacy risks through the whole life cycle of the data release.

Abstract
Purpose
In this article, the authors analyse a complex social process affecting historic public paths in rural areas in southern Spain. Despite the fact that urban populations are demanding the enhancement of this type of natural heritage for tourism, sports and recreational use, some parts of the network have been abandoned or usurped.
Design/methodology/approach
The study is multidisciplinary, comprising three interlinked studies. The cartographic study comprises an inventory of public paths in rural areas based on administrative sources. The legal study analyses local, regional and national regulations governing agricultural, environmental, heritage, sports and tourism uses of the infrastructure. The sociological study analyses social discourses on the uses of public paths, and identifies conflicts between farmers, landowners, environmentalists, sportspeople and tourists.
Findings
The preliminary results identified an important public paths network in Andalusia, approximately 160,000 km. The legal study found that there are laws regulating use, although local authorities do not monitor compliance or provide solutions to enhance management. The sociological study determined the attribution of environmental, cultural and economic value to public paths, but also the existence of conflicts between rural and urban populations.
Research limitations/implications
Given that this is ongoing research, only state of the art and some preliminary albeit sufficiently consistent results are presented.
Practical implications
The results could help to guide public policy and governance of public paths.
Social implications
Public paths promote rural development and a green/sustainable economy.
Originality/value
The research results and conclusions are original.

Abstract
Purpose
Cuenca, a World Heritage City, faces urban expansion as residents move to the outskirts, leaving the historic center abandoned and deteriorating. The challenge now is to relocate these spaces into sustainable and cohesive nodes. This research aims to identify cultural facility oversupply in the city center and understand the required usage for heritage buildings to promote a habitable, sustainable and cohesive historic center.
Design/methodology/approach
The study consisted of two phases. Firstly, a georeferenced spatial analysis and monthly usage frequency of each facility is proposed. Secondly, interviews explored the criteria for designating heritage buildings as cultural facilities. Additionally, a survey assessed urban habitability in three historic center parishes, measuring aspects like coverage, satisfaction and security from residents' perspectives.
Findings
The underutilization of cultural facilities demonstrates both inefficient heritage management and a lack of resident interest in cultural activities and neighborhood decision-making. Thus, ensuring collective ownership of heritage assets becomes crucial. Additionally, the municipality's approach to heritage must be reconsidered. While implementing a cultural program may seem faster and cheaper, the long-term cost-benefit of maintaining a cohesive historical center outweighs that of a dispersed city.
Originality/value
This paper calls for a fundamental reimagining of the concept of built heritage, emphasizing the need for a more inclusive and integrated approach that goes beyond museum and tourism-driven strategies. This perspective recognizes the importance of social, cultural and environmental sustainability in revitalizing the historic center, considering the broader context of the city and its diverse inhabitants.

Abstract
Purpose
The purpose of this study was to evaluate the effects of the addition of flaxseed and amaranth at different proportions on the hydration kinetics, colour and sensory qualities of instant-extruded cereals, important aspects related to the functionality and acceptability of food products.
Design/methodology/approach
Instant-extruded cereals were made with different proportions of flaxseed (6.6–9.3%), amaranth (18.7–33.1%), and maize grits (63.8–67.3%); and characteristics such as hydration kinetics, colour parameters and sensory properties were evaluated.
Findings
The kinetics of milk absorption showed that the extruded cereals maintained their texture and crispness for a sufficiently long time (≤20 min). The L*, a* and chroma* values of the extruded cereals were significantly affected (p < 0.05) by the flaxseed content. Sensory evaluation showed that all the extrudates had good acceptance in terms of flavour, texture, and colour attributes in relation to high-fibre commercial cereals; according to the preference test, they were as acceptable as commercial extruded cereals when consumed with milk. The addition of high-fibre and protein-containing grains such as flaxseed (8.6–9.3%) and amaranth (18.7–22.9%) in instant-extruded cereals allowed the production of products with acceptable physical and sensory characteristics.
Originality/value
In this study a novel instant-extruded cereal with flaxseed and amaranth was developed. The evaluation of the physical and sensory characteristics of instant-extruded cereals is essential to guarantee consumer acceptability, especially if functional ingredients with a high content of dietary fibre and protein are added.

Abstract
Purpose
The purpose of this paper is to examine the role played by different types of firm innovation on employee downsizing. Drawing on economic and management views, the authors aims to assess the potential positive or negative effect of different types of processes (i.e. new technology via the introduction of new equipment as well as new methods of organizing the workforce) and product (i.e. number of innovations) innovations on employee downsizing.
Design/methodology/approach
The empirical setting is a sample of Spanish manufacturing firms over the period 1994‐2006. The authors employ probit models for panel data as an empirical tool.
Findings
The results show a negative and significant effect of process innovations associated with acquiring and deploying new production equipment and product‐oriented innovations on the probability of carrying out important reductions in workforce. However, a positive and significant effect is found when process innovations are linked to the adoption of new methods of organizing the workforce.
Practical implications
Managers might play a significant role in employment creation, especially when they carry out process innovations related to the acquisition of complementary production assets (i.e. new equipment) and market highly innovative products. Policy makers might contribute to diminish the potential number of employees affected by firms’ downsizing strategies by designing, for example, public subsidies systems that deliberately prompt both types of innovations.
Originality/value
The authors make an effort to provide alternative explanations about why firms downsize, as they analyze different types of process and product innovations whose effects on employment (and, thus, downsizing) do not seem to be clear. Moreover, the paper furthers one's understanding of the effect of firm innovation by focusing on the potential effect of one type of process innovation which has not been examined until now: the adoption and implementation of new methods of organizing the workforce owing to new technology.

Abstract
Purpose – This chapter provides one aspect of the organizational side of the biology and politics enterprise.
Design/methodology/approach – This chapter provides a historical description of two organizations that help to structure the “business” of biology and politics: The International Political Science Association’s (IPSA) Research Committee #12 and the Association for Politics and the Life Sciences (APLS).
Findings – Research Committee #12 had its origins in the early 1970s, whereas APLS came about in the later 1970s. The discussion of these two organizations gives the reader a better sense of the twin enterprises. In the process of discussing APLS, the chapter also outlines the contributions of its professional journal, Politics and the Life Sciences.
Originality/value – Seldom has there been a detailed discussion of these two organizations in one place.
