Previous studies suggested that parenting is critically important in the development of both moral identity and compassion, but more research is needed concerning the stability of these effects and whether they carry over into adulthood. The present study addressed this issue by examining the link between a specific dimension of perceived parental style and compassion and the mediating role of moral identity in this relationship. The research sample comprised 208 adults aged 18 to 60 (M = 25.44, SD = 7.09, (...) 82.2% females). The participants completed self-report scales measuring perceived parental emotional warmth, compassion, and moral identity (i.e. moral self and moral integrity). Correlation analysis suggested that compassion was positively associated with all the measured variables. Mediation analysis results suggested that both facets of moral identity mediated the link between perceived parental emotional warmth and compassion. We discuss these results considering their importance for cultivating moral identity and compassion and the important role of parents in this regard. (shrink)

Cyber risk has become one of the greatest threats to firms in recent years. Accordingly, boards of directors must be continually vigilant about this danger. They have a duty to ensure that the companies adopt appropriate cybersecurity measures to manage the risk of cyber fraud. Boards should also ensure that the firm disclose material cyber risk and breaches. We examine how the board’s gender composition can influence the extent of such disclosure, based on a sample of the companies listed on (...) the S&P/TSX 60 Index over the period 2014–2018. Results show evidence of a positive association between the presence and level of cybersecurity disclosure and board gender diversity. However, the board must boast a critical mass of at least three women before this positive impact can be observed. Our findings contribute to the debate on the importance of gender diversity by adding the concept of the positive influence of heterogeneity on cyber disclosure. We also augment the literature on the critical mass of women in boardrooms by providing empirical evidence that three or more women constitute the threshold for better governance. Our study has important implications for investors, stakeholders and regulators. If investors wish to increase cybersecurity disclosure, they should ask for more diversified boards. Our findings support regulators in their efforts to increase women’s representation on boards by providing empirical evidence of better outcomes with this type of board composition. (shrink)

While attacks against members of the LGBT community are increasingly covered as hate crimes and are widely viewed as a form of repression, attacks on women are almost never covered as violations of human rights. We propose that until violence against women is recognized as a form of repression and a threat to the physical security of women, we cannot expect much to be done to prevent it. We posit that policies aimed at preventing violence against women are unlikely to (...) come about unless this abstract concept is connected, through a connection frame, to concrete crimes against women. We conducted a framing analysis of news coverage of all confirmed femicides in Massachusetts in 2013 and find that while journalists have the potential to draw these connection frames, they seldom put these killings in the context of violations of women’s rights.

À travers une analyse sémio-discursive et ayant comme repères trois journaux roumains de la presse d'information, l'étude met en lumière les principales ressources discursives mobilisées par la presse à l'occasion des référendums français et néerlandais sur la Constitution européenne. L'étude esquisse d'abord le contexte local qui consacrera le référendum comme un événement de politique extérieure atypique, vu ses implications sur le plan de l'adhésion de la Roumanie à l'UE. On analyse par la suite les principaux mécanismes discursifs qui ont permis (...) à la presse de gérer toute une mise en scène des émotions collectives. La récupération des contextes locaux européens, l'évaluation de l'«état d'esprit» bruxellois après le référendum ainsi que la valorisation d'un savoir expert personnalisant sont certains des mécanismes utilisés par la presse afin de ménager les sensibilités collectives et de rassurer sur le processus d'adhésion en cours. Cette gestion des émotions euphémisatrice actualise des pratiques médiatiques déjà instituées dans l'espace public roumain tout en contribuant à la consécration d'un imaginaire de la décision verticale.Through a discursive and semiotic analysis as benchmarks with three newspapers Romanian press information, the study highlights the main discursive resources mobilized by the press during the French and Dutch referenda on the European Constitution. The study outlines first the local context devote the referendum as an event of unusual foreign policy, given its implications for the accession of Romania to the EU. Analyzed by the following key discursive mechanisms that allowed the press to manage a staging of collective emotions. Recovery of European local contexts, the evaluation of the "state of mind" in Brussels after the referendum and the development of expert knowledge are customizing some of the mechanisms used by the press to collective sensibilities and reassure the accession process underway. The management of emotions updates euphémisatrice media practices already established in the Romanian public space while contributing to the consecration of a imaginary vertical decision. (shrink)

Alongside the institutionally constructed European identity, research shows that insights into citizens’ sense of belonging are valuable as well in assessing questions of identity. The tendency to conflate European identity with EU identity has spurred debates about the components that underlie European identification. The online subsidiarity adopted by the EU through e-platforms has allowed for a new form of citizenship where e-citizens legitimate the issues under debate. This article examines the contents of European and national identities in the e-debaters’ comments (...) posted on the Debating Europe platform. Drawing on narrative and discursive approaches, we propose a framework to operationalize the legitimation and identification categories used by e-debaters within their discursive construction of European identity. The qualitative empirical research shows three main legitimation clusters: the “EU as a loss,” “inclusive gain,” and “exclusive gain.” We discuss these findings within the broader context of Europeanization, identity multiplicity, and the conditions of the EU enlargement policy.

Besides Dracula, Ceauşescu, and Nadia Comăneci, monasteries constitute a permanent Romanian brand, inextricably linked in every foreign visitor's mind to Romanianness. Specific to Moldavia and Bucovina—the Eastern and Northern parts of Romania—these monasteries have attracted visitors for the past 500 years. The person visiting a sacred site is transformed from being merely a tourist into a pilgrim. The painting “The Ladder towards Heaven” at the Pângăraţi Monastery, for example, highlights the importance of the mental and physical involvement of the tourist-pilgrim (...) as an interactive participant in the process of self-discovery.

Douglas Hofstadter shows in his hybrid of fiction and mathematical introduction Gödel, Escher, Bach—An Eternal Golden Braid , how the paradoxes inherent in Gödel’s theorem .), Escher’s complex drawings and Bach’s compositional techniques are isomorphic across disciplines. From Latin in venire, to come upon something, the word invention already suggests an element of accident: finding something that is already there. This paper shows how Hofstadter’s discussions and fictionalisations of Bach’s two-part and three-part inventions, illuminate complex yet simple processes in aesthetic (...) work: coming upon, stumbling over, and ultimately writing stories out of one’s ideas and imagination. Looking at the book’s fragmented patterns via Derrida’s inventions of the ‘other’ the paper argues that the relation between imagination and inventiveness in Hofstadter is mediated by propositions on incompleteness and their paradoxical relation to ‘whole’ fragments.

This article assesses the relevance of Wittgenstein’s late philosophy for the study of online forms of communication. In particular, the article deals with the appropriateness of using the concept of language game for the purpose of describing what happens in a virtual community. Testing Wittgenstein’s concept of language game in online context, we also analyse the language practices of one specific virtual community (patterns of communication, style, roles of members, internal organization of this ‘form of life’).

ABSTRACT: This paper underlines the relationship between rhetoric and postmodernism. In lack of a unique definition, postmodernism is seldom described as a non-centred set of rhetorical, critical and discursive practices; rhetoric offers a fertile frame for the interpretation of postmodernism. In my approach, I analyze both the type of rhetoric through which we can grasp the current of postmodernism and the use of rhetoric inside the postmodern discursiveness. The former was born out of its relationship with modernism and from this (...) standpoint I am interested in investigating the rhetorical relevance of themes such as rupture, continuity, palimpsest, anamnesis, incompleteness. The latter is discussed mainly by focusing on the effects of the repositioning of rhetoric in postmodernism. These analyses create a cluster of motifs that constitute the nucleus of the contemporary rhetoric imaginary. RESUMO. Este trabalho evidencia a relação entre a retórica e o pós-modernismo. Na ausência de uma definição única, o pós-modernismo é muitas vezes como sendo um conjunto não centrado de práticas retóricas, críticas e discursivas. Dessa maneira, a retórica oferece um ambiente fértil de uma adequada interpretação do pós-modernismo. Dentro da minha abordagem, analisei tanto o tipo de retórica através do qual podemos entender o movimento pós-moderno, quanto o uso de retórica dentro da discursividade pós-moderna. O primeiro tipo de retórica nasceu do relacionamento com o modernismo e, nesse contexto, é investigada a relevância retórica de alguns temas como a ruptura, continuidade, palimpsesto, anamnese, incompletude. O segundo tipo de retórica é investigado especialmente através da concentração sobre os efeitos do reposicionamento da retórica no pós-modernismo. Essas análises se amparam em um conglomerado de razões que constitui o núcleo do imaginário da retórica contemporânea. (shrink)

The end of the Second World War produced a shift in the Soviet mode of legitimation; the original values of Marxism-Leninism were combined with those of patriotic nationalism in a new form of ideology in which the idea of The Great Patriotic War became one of the founding myths. Especially after Stalin’s death in 1953 and the beginning of the process of de-Stalinization, the Soviet political elites made an attempt to change their strategy by reducing reliance on coercion and strengthening (...) political legitimacy in order to gain compliance from the ruled population. The system of socialist ritual became one of the most important legitimation procedures. The political elites came to regard the system of ritual as an important factor in maintaining and strengthening the legitimacy of the regime and their own position in the power structure. (shrink)

Colm Tóibín’s 2009 novel Brooklyn accompanies Eilis Lacey, a native of Enniscorthy, Ireland of the 1950s on a reluctant voyage across the Atlantic. Her passage reconstructs a common experience of immigration and exile to New York for the Irish working class seeking to escape the lack of prospects in small-town Ireland after the Second World War. Caught as she is between two homes—the traditional Irish culture she emerges from and the new capitalist society of America to which she emigrates—Eilis is (...) placed in a polemical relationship to the public sphere, staked on multiple grounds of in-betweenness: she is a woman, Irish, and an exile. Belonging, for her, is posited on a complex understanding of the tensions between national and transnational identities. Eilis’s parochialism, at first, and cosmopolitanism, later on, are both decisive characteristics that become driving forces behind her social integration and marriage prospects. She is initially barred from promising job and marriage opportunities due to her naivety and lack of sophistication. As an Irish female immigrant, Eilis becomes in the course of the novel a cosmopolitan from the margins, one of the newly uprooted, and ultimately a split self. (shrink)

This study examines how the CSR committee and CSR-linked executive compensation jointly affect CSR performance as governance mechanisms. Prior studies provided mixed results on the CSR committee’s effect on CSR performance. We posit that a CSR committee has both a direct and an indirect positive effect on CSR performance, with CSR-linked compensation playing the role of mediator in the relationship. We base our analysis on a sample of 164 Canadian firms covering the period 2012–2018, for a total of 952 firm-year (...) observations. We propose a regression-based approach for our mediation research design. Our findings reveal that CSR-linked compensation mediates the CSR committee’s positive effect on performance, but the type of mediation depends on whether the performance is social or environmental. We provide evidence of both direct and indirect effects on environmental performance but only a positive indirect effect on social performance. These results suggest that demands from the firm’s internal and external stakeholders are treated differently, with the former receiving priority. (shrink)

As clinical trials end, little is understood about how participants exiting from clinical trials approach decisions related to the removal or post-trial use of investigational brain implants, such as deep brain stimulation (DBS) devices. This empirical bioethics study examines how research participants experience the process of exit from research at the end of clinical trials of implanted neural devices. Using a modified grounded theory study design, we conducted semi-structured, in-depth interviews with 16 former research participants from clinical trials of DBS (...) and responsive neurostimulation (RNS). Open-ended questions elicited motivations for joining the trial, understanding of study procedures at the time of initial informed consent, the process of exiting from research, and decisions about device removal or post-trial device use. Thematic analysis identified categories related to: limited preparedness for the end of research participation, straightforwardness of decisions to explant or keep the device, reconciling with the end of research participation, reconciling post-trial expectations, and achieving a sense of closure after exit from research. A preliminary theoretical model describes contextual factors influencing the process and experience of exit from research. Experiences of clinical trial participants should guide research practices to enhance the ethical design and conduct of clinical trials in DBS and other brain devices. (shrink)

The idea of agency has long been used in the nursing literature in the study of nurses' roles regarding the patients they take care of, but it has not often been used to study its relationship with nurses themselves and their status in the healthcare system. The purpose of this article is to analyze how the idea of agency is used in nursing research to better understand how we might advance our thinking around nurses' agency to shape nursing and healthcare (...) with an emancipatory intent. Based on the results of a literature review focused on the study of conceptions, treatments, and applications of the concept of agency in nursing, we present a critical discussion to reflect on the need to consistently define the idea of nurses' agency, to guide research concerned with this topic in theoretical frameworks with emancipatory and social change tenets, and to make a call to develop the idea of agency as a central one to rework nurses' relationship with themselves. The idea of agency provides a valuable analytical framework for the study of a wide range of issues around nurses' status in healthcare organizations and in the healthcare system while offering a means for nurses' emancipation.

Nurses have their own ways of talking about their experiences of injustice in healthcare organizations. The aim of this article is to describe how nurses talk about their work‐life experiences and discuss the discursive effects that arise from nurses' use of language regarding their political agency. To this end, we present the findings garnered from a study focused on exploring how nurses deploy their political agency to project their idea of social and political justice in public healthcare organizations and how (...) they face the challenges and uncertainties of (re)thinking their institutional order when it does not resonate with their professional ethos. We then discuss the implications that nurses' use of language has in relation to their ability to deploy their political agency to oppose the forms of injustice they face in their daily practice. We conclude by stating that careful attention should be placed on understanding the discursive implications of nurses' use of language on their individual and collective emancipation in healthcare organizations.

This article aims to present the life and work of German thinker Hartmut Rosa as a philosopher of interest for nursing. Although his theoretical framework remains fairly unknown in the nursing domain, its main key concepts open up a philosophical and sociological approach that can contribute to the understanding of a wide range of study phenomena related to nurses, nursing, and healthcare. The concepts of social acceleration, alienation, and resonance are useful to explore healthcare organizations' performance by bringing the time (...) dimension of modernity to the center; to grasp nurses' experiences of caring for patients; and to understand nurses as agents endowed with the capacity to deploy their political agency to create alternative forms of relationship to themselves, to others, and the world, challenging the institutional order of healthcare organizations when it fails to resonate with their professional ethos. In this article, we propose Hartmut Rosa's theoretical framework as a new and inspiring phenomenological and critical lens that should be further explored to advance knowledge concerning phenomena that are found at the crossroads of the nursing domain and other fields of knowledge.

Regression testing is applied whenever a code changes, ensuring that the modifications fixed the fault and no other faults are introduced. Due to a large number of test cases to be run, test case prioritization is one of the strategies that allows to run the test cases with the highest fault rate first. The aim of the paper is to present an optimized test case prioritization method inspired by ant colony optimization, test case prioritization–ANT. The criteria used by the optimization (...) algorithm are the number of faults not covered yet by the selected test cases and the sum of severity of the faults. The cost, i.e. time execution, for test cases is considered in the computation of the pheromone deposited on the graph’s edges. The average percentage of fault detected metric, as best selection criterion, is used to uncover maximum faults with the highest severity, and reducing the regression testing time. Several experiments are considered, detailed and discussed, comparing various algorithm parameter’s alternatives. A benchmark project is also used to validate the proposed approach. The obtained results are encouraging, being a cornerstone for new perspectives to be considered. (shrink)

Jusqu’à présent, les discussions au sein de la communauté universitaire et dans la littérature scientifique sur la conduite responsable en recherche (CRR), incluant l’intégrité scientifique et l’éthique de la recherche, ont principalement été menées par les chercheurs en sciences de la santé et en sciences fondamentales. Préoccupés, à juste titre, par des problèmes d’inconduite, leurs effets négatifs sur la rigueur scientifique et la confiance du public dans l’entreprise de la recherche, ces débats ont conduit à l’élaboration et à la mise (...) en œuvre de lignes directrices nationales et de politiques institutionnelles. Ces lignes directrices visent entre autres à promouvoir la CRR, notamment dans le but de prévenir ces inconduites. Cependant, pour garantir la pertinence et une application appropriée de ces normes à tous les domaines universitaires, il est nécessaire que les sciences humaines et sociales (SHS) contribuent plus directement à ces discussions. Un tel engagement devrait permettre d’exprimer les particularités disciplinaires et méthodologiques des SHS, dont certaines peuvent être très différentes des sciences appliquées et fondamentales. Cela permettrait également de s’assurer que la littérature sur la CRR ainsi que les politiques et les directives qui en découlent soient à la fois fondées sur des principes universellement généralisables, mais aussi appliquées avec nuance afin de refléter la diversité des pratiques disciplinaires. Dans ce chapitre, nous explorons trois grands domaines dans lesquels les SHS pourraient contribuer à façonner les discussions dans la littérature sur la CRR, tout en informant les chercheurs en SHS des meilleures pratiques en matière de CRR : l’autorat/paternité, la collaboration et l’autorégulation.

This paper integrates symbolic thought and experimental research. We hypothesized that symbolic narratives provide homeostasis for the complex adaptive system that is personality. Our interpretation of a dream was based, in part, on this hypothesis. We found that the dream retold the myth of Saturn. When, by direct experiment, we tried to falsify our interpretation, our results supported our interpretation and thereby supported our hypothesis. Previously, evidence for this hypothesis had been only anecdotal. __________________________________________ For an audio-record of entire class: (...) link is given on 1st page of the text you download from this page.

BackgroundPhysical activity is known to improve mental health, and is regarded as safe and desirable for uncomplicated pregnancy. In this novel study, we aim to evaluate whether there are associations between maternal physical activity during pregnancy and neonatal brain cortical development.MethodsForty-four mother/newborn dyads were included in this longitudinal study. Healthy pregnant women were recruited and their physical activity throughout pregnancy were documented using accelerometers worn for 3–7 days for each of the 6 time points at 4–10, ∼12, ∼18, ∼24, ∼30, (...) and ∼36 weeks of pregnancy. Average daily total steps and daily total activity count as well as daily minutes spent in sedentary/light/moderate/vigorous activity modes were extracted from the accelerometers for each time point. At ∼2 weeks of postnatal age, their newborns underwent an MRI examination of the brain without sedation, and 3D T1-weighted brain structural images were post-processed by the iBEAT2.0 software utilizing advanced deep learning approaches. Cortical surface maps were reconstructed from the segmented brain images and parcellated to 34 regions in each brain hemisphere, and mean cortical thickness for each region was computed for partial correlation analyses with physical activity measures, with appropriate multiple comparison corrections and potential confounders controlled.ResultsAt 4–10 weeks of pregnancy, mother’s daily total activity count positively correlated (FDR corrected P ≤ 0.05) with newborn’s cortical thickness in the left caudal middle frontal gyrus (rho = 0.48, P = 0.04), right medial orbital frontal gyrus (rho = 0.48, P = 0.04), and right transverse temporal gyrus (rho = 0.48, P = 0.04); mother’s daily time in moderate activity mode positively correlated with newborn’s cortical thickness in the right transverse temporal gyrus (rho = 0.53, P = 0.03). At ∼24 weeks of pregnancy, mother’s daily total activity count positively correlated (FDR corrected P ≤ 0.05) with newborn’s cortical thickness in the left (rho = 0.56, P = 0.02) and right isthmus cingulate gyrus (rho = 0.50, P = 0.05).ConclusionWe identified significant relationships between physical activity in healthy pregnant women during the 1st and 2nd trimester and brain cortical development in newborns. Higher maternal physical activity level is associated with greater neonatal brain cortical thickness, presumably indicating better cortical development. (shrink)

Wearing facial masks became a common practice worldwide during the COVID-19 pandemic. This study investigated (1) whether facial masks that cover adult faces affect 4- to 6-year-old children’s recognition of emotions in those faces and (2) whether the duration of children’s exposure to masks is associated with emotion recognition. We tested children from Switzerland (N = 38) and Brazil (N = 41). Brazil represented longer mask exposure due to a stricter mandate during COVID-19. Children had to choose a face displaying (...) a specific emotion (happy, angry, or sad) when the face wore either no cover, a facial mask, or sunglasses. The longer hours of mask exposure were associated with better emotion recognition. Controlling for the hours of exposure, children were less likely to recognise emotions in partially hideen faces. Moreover, Brazilian children were more accurate in recognising happy faces than Swiss children. Overall, facial masks may negatively impact children’s emotion recognition. However, prolonged exposure appears to buffer the lack of facial cues from the nose and mouth. In conclusion, restricting facial cues due to masks may impair kindergarten children’s emotion recognition in the short run. However, it may facilitate their broader reading of facial emotional cues in the long run. (shrink)

A ventilação mecânica invasiva (VMI) tem como objetivo melhorar trocas gasosas e reduzir o trabalho ventilatório de pacientes críticos. O desmame em traqueostomia é realizado usando modo ventilatório espontâneo e períodos fora da VMI de forma progressiva. O modo ventilatório utilizado pode ser, entre outros, ventilação por pressão (PSV) ou ventilação proporcional assistida (PAV). O objetivo foi comparar o uso do modo PSV e PAV no desmame de pacientes traqueostomizados. Foram recrutados 14 indivíduos, alocados em dois grupos, PSV e PAV, (...) realizaram protocolo de desmame e ao final foram avaliadas as variáveis tempo de VMI em traqueostomia, tempo de desmame ventilatório e taxas de sucesso de desmame. O grupo PAV obteve uma mediana melhor no desfecho dias de desmame, mas sem diferença estatisticamente significativa (p=0,459). Nosso estudo não sustenta o modo PAV como melhor escolha para desmame em pacientes traqueostomizados, são necessários novos estudos com tamanho amostral maior. (shrink)

To identify how digital media are being used by community-led initiatives of the Centro Region of Portugal, and to identify the requirements that a digital platform for mediation between agents in the territory should have, two focus groups were conducted, involving six small-sized community-led initiatives and six larger-sized community-led initiatives. This article details the results of these focus groups, according to the following main categories: use of existing communication and mediation tools; the purpose of use of digital tools; type of (...) experiences prompted by digital tools and attributes and features desired in a digital platform to support community-led initiatives. The results show differences between the use and needs of digital tools by small- and larger-sized initiatives and offer interesting insights to prototype an innovative digital solution, to enhance the actions of community-led initiatives. A reference framework for digital mediation strategies and a mobile app prototype were developed, based on these surveys. The article contributes with an analytical view about the development of digital solutions, which aim to strengthen the relationship among agents of local communities and promote mediation mechanisms among all stakeholders in territorial-based innovation.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Recent evidence suggests that probabilistic grammars may be modulated by communication mode and genre. Accordingly, the question arises how complex language users’ lectal competence is, where complexity is proportional to the extent to which choice-making processes depend on the situation of language use. Do probabilistic constraints vary when we talk to a friend compared to when we give a speech? Are differences between spoken and written language larger than those within each mode? In the present study, we aim to approach (...) these questions systematically. Guided by theorizing in cognitive (socio)linguistics and using logistic regression based on corpus materials, we analyzed the dative alternation with give (The government gives farmers money vs. The government gives money to farmers) in four broad registers of English: spoken informal, spoken formal, written informal, and written formal. Corpus analysis was supplemented with a scalar rating experiment. Results suggest that language users’ probabilistic grammars vary as a function of register. (shrink)

A fluent economical collaboration between countries is a major need. European flows of trade and people are supported by efficient connections between main localities from a geographic region, in many cases overriding national borders. This paper introduces three traveling salesmen problem instances based on freely available geographic coordinates of the main cities of France, Portugal and Spain. These instances are unified, generating other four larger instances: three with all pairs of countries and one instance with the settlements from all the (...) three countries. The study includes an analysis of quality of solutions for a version of branch & cut algorithm and some hybrid heuristics including the Lin–Kernighan algorithm. $Bor\mathring{u}vka$, Quick$Bor\mathring{u}vka$ and Greedy algorithms are also used in the hybrid approaches in order to obtain a potential beneficent initial solution for the Lin–Kernighan algorithm. Concorde solver, nowadays state-of-the-art exact software, together with the already mentioned algorithms, is used to test and furthermore analyze the new TSP instances. Some results are represented using online services such as Google Maps, showing the potential integration of the Concorde’s optimum results into commercial routing applications. The very good results provided by the Lin–Kernighan method allow its usage for real medium-sized routing instances. (shrink)

Meeting the security requests in transportation is nowadays a must. The intelligent transport systems represent the support for addressing such a challenge, due to their ability to make real-time adaptive decisions. We propose a new variant of the travelling salesman problem integrating security constraints inspired from ITSs. This optimization problem is called the secure TSP and considers a set of security constraints on its integer variables. Similarities with fuzzy logic are presented alongside the mathematical model of the introduced TSP variant.
