IntroductionIncorporating technology in cognitive interventions represents an innovation, making them more accessible, flexible, and cost-effective. This will not be feasible without adequate user-technology fit. Bearing in mind the importance of developing cognitive interventions whose technology is appropriate for elderly people with cognitive impairment, the objective of this systematic review was to find evidence about usability and user experience measurements and features of stimulation, training, and cognitive rehabilitation technologies for older adults with mild cognitive impairment or dementia.MethodThe Medline, PubMed, Scopus, ScienceDirect, (...) and PsycINFO databases were searched for literature published in the last 10 years, and three researchers independently reviewed potentially eligible studies, following specific inclusion criteria. A systematic review of the studies was conducted, presenting a qualitative synthesis of usability and UX measures with their outcomes, study characteristics and features of the cognitive intervention technologies.ResultsTen studies were selected: five were cognitive stimulation and five were cognitive training. Most of them were computer-based programs with a serious game format. Efficiency and effectiveness were the most frequent measurements used for collecting objective usability data, showing that elderly people with cognitive impairment require more time and help but can complete tasks. Regarding UX or subjective usability data, questionnaires and scales were the most used methods, reporting positive experience despite certain difficulties with the interface in five studies.ConclusionMeasuring usability and UX in cognitive intervention technologies for older adults with MCI or dementia provides an integrated view that can contribute to their development according to the needs and characteristics of the target population. More research is required to include this population group in usability and UX studies, as well as standardized tools and consensus on the relationship of these terms to guarantee the future effectiveness of cognitive intervention technologies.Review registrationThis review was registered in the PROSPERO International Register of Systematic Review Protocols.

La presente contribución recoge el diálogo mantenido entre distintos filósofos del Derecho a propósito de la última obra del Profesor Massimo La Torre “Il diritto contro se stesso. Saggio sul positivismo giuridico e la sua crisi”. Al hilo del trabajo del citado autor, los participantes reflexionan sobre preguntas centrales para la teoría y filosofía del Derecho contemporánea: ¿cuál es la naturaleza del Derecho? ¿es el razonamiento jurídico eminentemente moral? ¿qué lugar debe ocupar la práctica jurídica en su conceptualización? ¿qué (...) lugar ocupa la fuerza en el Derecho?

La Doctrina penal contemporánea recurre al principio de ultima ratio para satisfacer la tarea principal de reducir al máximo la arbitrariedad del Derecho penal, pues a través de su significado, la legitimidad del delito y de la pena se somete a la condición de la inexistencia axiológica y empírica de otros recursos jurídicos menos drásticos para solventar idóneamente el conflicto que genera su apertura. No obstante, la deriva punitivista en que ha degenerado la necesaria expansión del Derecho penal en la (...) sociedad del riesgo, pone en duda su verdadera capacidad limitadora, especialmente por su escasa vinculación a los poderes públicos. Pero nada más lejos de la realidad, el desarrollo actual de la Dogmática de los Derechos Fundamentales permite a la Doctrina penal afirmar que, en el Estado constitucional, el Derecho penal mínimo es a su vez el Derecho penal máximo permitido por la Constitución.

RESUMEN Más allá de ser un mero recurso ornamental, la alusión a los perros que hace Platón en diferentes pasajes de la República parece realizarse con miras a defender importantes tesis políticas. Este artículo tiene como propósito develar algunas de estas tesis y busca defender la elección que hace Platón del perro, de entre otros animales, para caracterizar la figura del guardián y del filósofo. El texto aborda la analogía presentada en República según la cual la disposición natural para vigilar (...) es el elemento común que comparte un buen cachorro con un joven de buen linaje y pone en el centro de su interés el rol que tiene el perro, descendiente de un antepasado más bestial y salvaje, el lobo, por ser capaz de sintetizar fiereza y mansedumbre por medio del aprendizaje y la domesticación. ABSTRACT Plato's reference to dogs in different passages of the Republic is more than a mere embellishment; it also serves to defend important political theses. The purpose of this article is to reveal some of these theses and to defend the author's choice of the dog, among other animals, to characterize the figures of the guardian and of the philosopher. The text discusses the analogy presented in the Republic according to which the natural disposition to guard is the common element shared between a puppy and a young man from good descent. The article focuses on the dog's role - descending from a wilder and more beastly animal, the wolf - as that of being able to synthesize fierceness and gentleness through learning and domestication.

Algunos autores contrarios a la práctica constitucional actualmente dominante han defendido una rigidez constitucional “mínima” como una forma “débil” del constitucionalismo en la que la voluntad mayoritaria puede identificar el alcance de los derechos fundamentales por encima de las determinaciones judiciales. El objetivo de este trabajo es plantear algunas reflexiones críticas sobre dicha propuesta, adoptando para ello como parámetro normativo la racionalidad intrínseca de la práctica constitucional contemporánea en las democracias liberales. Dicha argumentación crítica avanza del siguiente modo: en primer (...) lugar, se discute la distinción formal entre sistemas de control jurisdiccional “fuerte” y “débil”; en segundo lugar, se pone en duda la supuesta relevancia de la reforma constitucional en la concreción histórica de los derechos básicos; y, por último, se rechaza la rigidez constitucional mínima entendida como parte de un modelo constitucional genuinamente alternativo diseñado para superar la práctica constitucional dominante.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Seeing Red: Indigenous Land, American Expansion, and the Political Economy of Plunder in North America by Michael John WitgenGeronimo Barrera de la TorreSeeing Red: Indigenous Land, American Expansion, and the Political Economy of Plunder in North America BY MICHAEL JOHN WITGEN Williamsburg, Va., and Chapel Hill, N.C.: Omohundro Institute for the Study of Early American History and Culture and the University of North Carolina Press, 2022The colonial projects (...) of nation-states in the Americas have defined the relationship between states and Indigenous peoples by means of [End Page 138] dispossession, as Anishinaabeg thinker Leanne Betasamosake Simpson asserts.1 Seeing Red delves into the processes through which dispossession of Indigenous land became the ideology and systematic practice behind US expansion as Indigenous communities struggled to reshape their place in the new context. The book carefully details the settler- colonial ideology and logic of elimination that permeated US territorial expansion over the Northwest Territories at the end of the eighteen and the first decades of the nineteenth centuries. Seeing Red thoroughly examines the complex context of dispossession by the US colonial power, centering on Anishinaabeg communities, the “mix- race” population, and the different Indigenous people inhabiting this region. However, the book focuses on what the author names “unthinkable history,” following Michel- Rolph Trouillot’s argument that this region, and the whole continent, was conceived as an unsettled territory instead of belonging to many Indigenous peoples. Thus, the text explores Indigenous and mixed- raced communities’ political imaginaries and imagined futures to retain autonomy and territory.Author Michael John Witgen is a citizen of the Red Cliff Band of Lake Superior Ojibwe and a professor in the Department of History and the Center for the Study of Ethnicity and Race at Columbia University. His research centers on the complex relations between Indigenous people and settler colonizers in the Great Lakes and the Northwest Territories. Seeing Red expands his previous analysis of race, ethnicity, and citizenship intersections, bringing to the fore Indigenous people’s history to rethink the statemaking process in the United States.This book’s pages show that theft lies at the foundation of wealth transfer from Indigenous territories to the United States government and white citizens. The white settler ideology, based on a “doctrine of discovery,” established a stark division between the civilized and uncivilized to rationalize, among other things, the theft of Indigenous people. This is a central argument of the book that signals how the civili zation project underpinning the territorial expansion of the United States was based on the transformation of commons into private property. Indigenous land became critical in the “political economy of plunder” advanced by the state and the meaning of “native” as a racial categorization of exclusion. Chapter 1 explores this economy of plunder by detailing the advancement of the settler frontier through different [End Page 139] mechanisms, such as the treaty policy— subsequently violated by the state— and territory surveying to make land legible for the state and cheap for settlers. It is worth mentioning that the book contains historical and thematic maps that visually represent the ideology of wilderness behind the colonization project and evidence of the territorial extent of dispossession suffered by Indigenous communities. However, this crusade to dispossess Indigenous peoples from their territory also rested on the national mythology that strengthened the trope of Indigenous vanishing. The author shows how during the years of the study, the Indigenous population was not vanishing but immersed in an intricate social world and transregional trade networks. Chapter 2 explores such context, following the story of an Ojibwe man to evidence the context in which settlers and federal officials relied on Indigenous customs to profit from the fur trade while using ties with communities to further land cessions.Mix- race families played a crucial role in expanding the settler frontier through treaty negotiations but remained marginalized as they identified themselves as both Natives and US citizens. Chapter 3 examines the significance of mixed- raced families, particularly women, in establishing and expanding missions’ schools that relied on their domestic and linguistic labor. Moreover, it shows the intricate landscape of the civilization mission that depended on the complex networks that had created... (shrink)

With the aim of giving this thesis a phenomenological foundation I approach the Heideggerian reflection on the nearness in five levels, beginning with the usual definition of nearness as “short distance” and ending with its identification with the language. My approach to this matter focuses exclusively on the late work of Heidegger. (shrink)

With the advent of the cloud computing model allowing a shared access to massive computing facilities, a surging demand emerges for the protection of the intellectual property tied to the programs executed on these uncontrolled systems. If novel paradigm as confidential computing aims at protecting the data manipulated during the execution, obfuscating techniques (in particular at the source code level) remain a popular solution to conceal the purpose of a program or its logic without altering its functionality, thus preventing reverse-engineering (...) on the program even with the help of computing resources. The many advantages of code obfuscation, together with its low cost, makes it a popular technique. This paper proposes a novel methodology for source code obfuscation that can be used together with other traditional obfuscation techniques, making the code more robust against reverse engineering attacks. Three program complexity metrics are used to define three different single-objective combinatorial optimization versions of the problem, which are solved and analysed. Additionally, three multi-objective problems are defined, those considering each of the selected metrics together with the program execution time, in order to avoid strong obfuscations penalizing the performance. The goal of the defined problems is to find sequences of LLVM optimizations that lead to highly obfuscated versions of the original code. These transformations are applied to the back-end pseudo-assembly code (i.e., LLVM Intermediate Representation), thus avoiding any further optimizations by the compiler. Classical genetic algorithms (GAs) are used to solve the studied problems, namely a basic cellular GA for the single-objective problems and the popular NSGA-II for the multi-objective ones. The promising results show the potential of the proposed technique. (shrink)

This book develops a novel approach to distributive justice by building a theory based on a concept of desert. As a work of applied political theory, it presents a simple but powerful theoretical argument and a detailed proposal to eliminate unmerited inequality, poverty, and economic immobility, speaking to the underlying moral principles of both progressives who already support egalitarian measures and also conservatives who have previously rejected egalitarianism on the grounds of individual freedom, personal responsibility, hard work, or economic efficiency. (...) By using an agnostic, flexible, data-driven approach to isolate luck and ultimately measure desert, this proposal makes equal opportunity initiatives both more accurate and effective as it adapts to a changing economy. It grants to each individual the freedom to genuinely choose their place in the distribution. It provides two policy variations that are perfectly economically efficient, and two others that are conditionally so. It straightforwardly aligns outcomes with widely shared, fundamental moral intuitions. Lastly, it demonstrates much of the above by modeling four policy variations using 40 years of survey data from the Panel Study of Income Dynamics. (shrink)

RESUMEN Juan Marinello Vidaurreta, eminente trabajador de las letras, que no cambió la pluma por la política, sino que hizo de la política incesante gestión de creación espiritual. Vivió tres etapas decisivas de Cuba: los rezagos de la colonia española; la República mediatizada, que combatió; y el socialismo, que ayudó a consolidar. El objetivo es demostrar la confluencia del pensamiento martiano y marxista desde el análisis de la cultura en la obra de Juan Marinello Vidaurreta. Se asumió la concepción dialéctica (...) materialista como metodología general para conocer el objeto de investigación en sus antecedentes y tendencias actuales. Además permitió ampliar el conocimiento sobre el tema objeto de estudio, a través del análisis de texto, el contenido y el discurso; la crítica de fuentes posibilitó extraer inferencias a partir de la teoría preexistente y la información empírica acopiada. El pensamiento marinelliano se fue formando como resultado de la influencia del movimiento progresista cubano, del pensamiento martiano y marxista-leninista, lo más avanzado del pensamiento latinoamericano y universal. Subyace en su obra una concepción integradora y totalizadora de la cultura, de base martiana y marxista. ABSTRACT Juan Marinello Vidaurreta eminent worker of the letters that did not change the pen by the policy, but that made of the policy, incessant management of spiritual creation. He lived three decisive stages of Cuba: the lags of the Spanish colony; the mediated Republic, which fought; and socialism, which helped to consolidate. The objective is to demonstrate the confluence of Marti's and Marxist thinking from the analysis of culture in the work of Juan Marinello Vidaurreta. The dialectical materialist conception was assumed as general methodology to know the object of research in its antecedents and current trends. In addition it allowed expanding the knowledge on the subject under study, through the analysis of text, content and discourse; the critique of sources made it possible to draw inferences from the preexisting theory and the empirical information collected. Marinellian thought was formed as a result of the influence of the Cuban progressive movement, of Marti and Marxist-Leninist thought, the most advanced of Latin American and universal thought. It underlies in his work an integrative and totalizing conception of the culture, of Marti base and marxist. (shrink)

In cybersecurity, there is a call for adaptive, accurate and efficient procedures to identifying performance shortcomings and security breaches. The increasing complexity of both Internet services and traffic determines a scenario that in many cases impedes the proper deployment of intrusion detection and prevention systems. Although it is a common practice to monitor network and applications activity, there is not a general methodology to codify and interpret the recorded events. Moreover, this lack of methodology somehow erodes the possibility of diagnosing (...) whether event detection and recording is adequately performed. As a result, there is an urge to construct general codification and classification procedures to be applied on any type of security event in any activity log. This work is focused on defining such a method using the so-called normalized compression distance (NCD). NCD is parameter-free and can be applied to determine the distance between events expressed using strings. As a first step in the concretion of a methodology for the integral interpretation of security events, this work is devoted to the characterization of web logs. On the grounds of the NCD, we propose an anomaly-based procedure for identifying web attacks from web logs. Given a web query as stored in a security log, a NCD-based feature vector is created and classified using a support vector machine. The method is tested using the CSIC-2010 data set, and the results are analyzed with respect to similar proposals. (shrink)
