The Next Release Problem (NRP) is a combinatorial optimization problem that aims to find a subset of software requirements to be delivered in the next software release, which maximize the satisfaction of a list of clients and minimize the effort required by developers to implement them. Previous studies have applied various metaheuristics, mostly genetic algorithms. Estimation of Distribution Algorithms (EDA), based on probabilistic modelling, have been proved to obtain good results in problems where genetic algorithms struggle. In this paper we (...) propose to adapt three EDAs to tackle the multi-objective NRP in a fast and effective way. Results show that EDAs can be applicable to solve the NRP with rather good quality of solutions. Furthermore, we prove that their execution time can be significantly reduced using a per-iteration solution subset selection method while maintaining the overall quality of the solutions obtained, and they perform the best when limiting the search time as in an interactive tool that requires fast responsiveness. The experimental framework, code and datasets have been made public in a code repository. (shrink)

Este artículo de revisión examina la importancia que tienen las comunidades microbianas que colonizan los ambien­tes y equipos de procesado de alimentos formando biopelículas o biofilms en la persistencia microbiana en la industria alimen­taria y consecuentemente, en la seguridad y la calidad de los alimentos. La atención se centra especialmente en biopelículas formadas por microorganismos no deseados, es decir, microor­ganismos alterantes y patógenos. Se presenta información so­bre la variabilidad intraespecífica en la formación, la ecología y la arquitectura de las biopelículas, (...) y los factores que influyen en su formación. Asimismo, se resume la información disponible sobre nuevos agentes o estrategias para el control de la forma­ción o eliminación de biopelículas. (shrink)

The use of technologies like artificial intelligence can drive productivity growth, efficiency and innovation. The goal of this study is to develop an anomaly detection method for locating flaws on the surface of sandwich panels using YOLOv5. The proposed algorithm extracts information locally from an image through a prediction system that creates bounding boxes and determines whether the sandwich panel surface contains flaws. It attempts to reject or accept a product based on quality levels specified in the standard. To evaluate (...) the proposed method, a comparison was made with a sandwich panel damage detection method based on a convolutional neural network and methods based on thresholding. The findings show that the proposed method, which is based on an object detector, is more accurate than the alternatives. The characteristics of the model, which can reject or accept a product according to the standard and limit allowable manufacturing flaws to obtain a quality product, also enable this system to improve industrial standards for producing sandwich panels while increasing speed.

The aim of the present study was to carry out a qualitative and quantitative synthesis of the existing literature studying the relationship between emotional intelligence and risk behavior. We conducted a systematic review and meta-analysis of the scientific evidence available relating both constructs. Particular attention was paid to identifying possible differences in this relationship as a function of the different conceptualizations of EI and the risk domain. The study was conducted following the Cochrane and PRISMA guidelines. Our results revealed a (...) significant negative relationship between EI and health-related risk behaviors. However, this relationship was not observed in other risk domains such as finance and gambling. The relationship between EI and risk behavior differed according to the risk domain studied, which supports the notion that risk is a domain-specific construct. The results associated with the health-related risk behaviors are consistent with existing literature about the positive impact of emotional abilities on the health domain. A more complete understanding of the emotional mechanisms that underlie risk behavior could help to establish action guidelines and improve programmes to prevent and reduce the negative effects of risk behavior on our society.

The concept of mental privacy can be defined as the principle that subjects should have control over the access to their own neural data and to the information about the mental processes and states that can be obtained by analyzing it. Our aim is to contribute to the current debate on mental privacy by identifying the main positions, articulating key assumptions and addressing central arguments. First, we map the different positions found in current literature. We distinguish between those who dismiss (...) concerns about mental privacy and those who endorse them. In this latter group, we establish a further disagreement between conservative and liberal strategies to protect mental privacy. Then, we address the first discussion by articulating and criticizing different skeptical views on mental privacy. Finally, we try to identify what are the unique features of neural data and examine how they may be connected to the ways in which neurotechnological mindreading could put mental privacy at risk. We suggest that even if neural data is unique, it may not require new strategies to protect people from its misuse. However, identifying the special features and risks of neurotechnological mind-reading is necessary for the second discussion on mental privacy to properly take off. (shrink)

Uno de los principales problemas de la filosofía de la psicopatología contemporánea consiste en definir qué tipo de estados mentales son aquellos que denominamos delirantes. A esto se le ha denominado el “problema tipológico de los delirios”. El principal objetivo de este artículo es examinar las principales alternativas filosóficas contemporáneas a este problema: el doxasticismo—de acuerdo con el cuál los delirios deben ser caracterizados como creencias—y al anti-doxasticismo—el cuál niega el estatuto doxásticos de los delirios y ofrece una caracterización alternativa. (...) Para examinar el debate, el artículo presentará las principales características de ambas posiciones y sus fundamentos. Después, examinaremos los principales argumentos esgrimidos contra el doxasticismo y las respuestas y contraargumentos por parte de las alternativas doxásticas. Finalmente, expondremos algunas cuestiones conceptuales y desafíos abiertos relacionados con el debate y que, a nuestro juicio, deberían de marcar la hoja de ruta de los filósofos de la mente interesados en los delirios en los próximos años.

Los fenómenos que suelen asociarse con los sistemas complejos, como la emergencia o la autorregulación, parecen estar envueltos en cierta oscuridad. En primer lugar, las definiciones ofrecidas tienden a ser demasiado generales e inclusivas. En segundo lugar, no se suele aclarar el estatuto de este tipo de fenómenos: si son enteramente debidos al sujeto, o si poseen partes esenciales no reducibles a ningún otro fenómeno. El presente artículo analiza, desde el punto de vista de los sistemas complejos, las nociones de (...) emergencia y autorregulación. Se discuten los principales problemas que estas presentan y se perfilan algunas soluciones que podrían usarse de cara a elaborar una ontología de los sistemas complejos. Haciendo uso de estas soluciones, se proponen algunas definiciones de los principales fenómenos que componen un sistema complejo para, finalmente, ofrecer una definición de este tipo de sistema. Estas definiciones y soluciones se elaboran mediante el uso de herramientas filosóficas tales como la mereología o la teoría de la fundamentación. (shrink)

El artículo es uno de los resultados de la tesis denominada: El derecho administrativo desde el nuevo contexto constitucional a partir del cine colombiano: Dos mujeres y una vaca y El abrazo de la serpiente, realizada como trabajo final para la Maestría en Derecho Administrativo de la Universidad Autónoma Latinoamericana. En el artículo Cine y Derecho se plantean como dos producciones culturales de honda trascendencia en las sociedades actuales y, particularmente el cine aborda nuevas miradas sobre diversos fenómenos sociales, políticos (...) y jurídicos, que le permite evidenciar matices, lecturas y puntos de vista. Por esto el artículo tiene como objetivo repensar el Derecho Administrativo utilizando el análisis fílmico como herramienta para descifrar las conexiones entre cine y ésta disciplina jurídica. Para ello se analizan dos películas en función de visibilizar sus conexiones con el Derecho Administrativo. En Dos mujeres y una vaca se evidencia que la película constituye una interpelación desde el séptimo arte a una sociedad que no se reconoce en la memoria de la guerra que ha padecido y a un Estado que no garantiza eficazmente las seguridades vitales, derechos y propiedades de los ciudadanos. En el caso El abrazo de la serpiente la película constituye un llamado para que el Estado fomente una visión más amplia y holística de la naturaleza que reconozca la integralidad y codependencia de todos los elementos naturales en el ecosistema. Ambas películas hacen un llamado al Estado que supone generar un cambio de paradigma, transformar profunda y fundamentalmente la administración pública, orientar la vocación de servicio público al bien común.

Este artículo pretende realizar un análisis semiótico del rito dancístico del pascol, el cual se distingue por ser una de las prácticas culturales más importantes de los indígenas rarámuri que radican en la región de barrancas de la sierra occidental del noroeste de México. A través del análisis de la semiosis de este rito dancístico intentaremos mostrar cómo es el proceso de significación interpretativa que le otorgan los rarámuri para explicar su cosmovisión. Se tendrá como finalidad dar cuenta que esta (...) práctica cultural es un símbolo esencial del proceso de la asociación de signos cuya acción o influencia compone una parte sustantiva de la cosmovisión de este grupo étnico, que tiene entre sus principales funciones mantener algunos preceptos socioculturales para la estabilidad futura de las familias y la comunidad.

A group of philosophers suggests that a sense of mineness intrinsically contained in the phenomenal structure of all conscious experiences is a necessary condition for a subject to become aware of himself as the subject of his experiences i.e. self-awareness. On this view, consciousness necessarily entails phenomenal self-awareness. This paper argues that cases of delusions of thought insertion undermine this claim and that such a phenomenal feature plays little role in accounting for the most minimal type of self-awareness entailed by (...) phenomenal consciousness. First, I clarify the main view endorsing this claim i.e. the Self-Presentational View of Consciousness and formulate the challenge from thought insertion. After, I offer a systematic evaluation of all the strategies used by the advocates of this view to deal with this challenge. Finally, I conclude that most of these strategies are unsatisfactory for they rest in unwarranted premises, imprecisions about the agentive nature of cognitive experiences, and especially, lack of distinction between the different ways in which subjects can become aware of their own thoughts.

The main goal of this article is to present Negative Dialectics as a central theme in the Adorno’s thought. In this work Adorno develops the antinomies that there are in the concept of instrumental reason, in order to assert the necessity for a new notion of rationality: a dialectical, negative and materialistic reason, which holds, at the same time, the non identity between subject-object, thought and reality. In this way Philosophy becomes critique of Idealism because this philosophical system defends the (...) “identity thinking” and the irrational society that supports, making a true freedom impossible. Instead of this conception Adorno defines Metaphysics as “negative dialectics” and antisystem, whose method is the analysis of thinking’s models, as a result of his own critical epistemology.

Positive Psychology has turned its attention to the study of emotions in a scientific and rigorous way. Particularly, to how emotions influence people’s health, performance, or their overall life satisfaction. Within this trend, Flow theory has established a theoretical framework that helps to promote the Flow experience. Flow state, or optimal experience, is a mental state of high concentration and enjoyment that, due to its characteristics, has been considered desirable for the development of the performing activity of performing musicians. Musicians (...) are a population prone to health problems, both psychological and physical, owing to different stressors of their training and professional activity. One of the most common problems is Musical Performance Anxiety. In this investigation, an electronic intervention program was carried out for the development of psychological self-regulation skills whose main objective was to trigger the Flow response in performing musicians and the coping mechanism for Musical Performance Anxiety. A quasi-experimental design was used with a control group in which pre- and post-measures of Flow State, Musical Performance Anxiety and, also, Social Skills were taken. Sixty-two performing musicians from different music colleges in Spain participated in the program. Results indicated that the intervention significantly improved Flow State, and Sense of Control, and decreased Music Performance Anxiety, and self-consciousness of the participants in the EG but not CG. The changes in the EG after the program showed the inverse relationship between Flow and Anxiety. Two important theoretical factors of both variables, such as worry and the feeling of lack of control, could be involved. The results are under discussion and future lines of research are proposed.

Despite the diagnostic relevance of thought insertion for disorders such as schizophrenia, the debates about its aetiology are far from resolved. This paper claims that in paying exclusive attention to the perceptual and cognitive impairments leading to delusional experiences in general, current deficit approaches overlook the role that affective disturbances might play in giving rise to cases of thought insertion. In the context of psychosis, affective impairments are often characterized as a consequence of the stress and anxiety caused by delusional (...) episodes. However, here I explore some of the conceptual and empirical reasons to think that affective problems might in fact play a crucial doxastic role in the aetiology of thought insertion. Finally, I conclude by proposing a way of integrating the main insights of my analysis with the current ‘two-factor’ deficit approach to thought insertion and I explore the potential adaptive role that some delusions might have within this framework.

After examining some of the most fundamental aspects of the general concept of ‘neuroright’ in the current discussion, this paper analyzes the concept of ‘the mental’ contained in the very first law of neurorights in the world currently under discussion in the Senate of the Republic of Chile (Bulletin 13.828-19 of the Chilean Senate). It is claimed that the lack of specificity of the target notion might not only posit difficulties for the creation of specific legal frameworks for the protection (...) of subjects from potential misuses of neurotechnologies with access to neural data, but it might also make very difficult the process of decision-taking when interpreting the law.

BackgroundAlcohol use is one of the main risk factors that leads to detrimental health effects and support for a transdiagnostic approach to alcohol use disorders is growing. However, the role of transdiagnostic predictors of problematic alcohol consumption in Ecuador are understudied.ObjectiveThe aim of this study was to examine gender differences in psychological stress and inflexibility as transdiagnostic predictors of problematic alcohol consumption in a large sample of college students in Ecuador.MethodsA total of 7,905 college students were surveyed using the following (...) standardized scales: Alcohol Use Disorders Identification Test, Perceived Stress Scale-14, and Acceptance and Action Questionnaire. Macro Process for SPSS was used to analyze mediation and moderation effects.ResultsReported alcohol consumption was significantly higher in men than women students. On the other hand, women reported significantly higher levels of perceived stress and psychological inflexibility than men students. Gender, age, psychological stress, and inflexibility were significant predictors of alcohol consumption. Moreover, psychological inflexibility mediated the impact of stress on alcohol consumption, particularly in women.DiscussionResults of this study support psychological stress and psychological inflexibility as critical transdiagnostic variables related to increased rates of alcohol consumption among Ecuadorian college students. These conclusions contribute to the development of transdiagnostic comprehensive programs, which encompasses promotive, preventive, and treatment services that allow to alleviate the burden of alcohol, as well as to enrich the growing research on alcohol consumption in this population from a gender perspective.

RESUMEN Una atribución de agencia mental es definida como el acto de asignar el inicio o autoría de un pensamiento en primera persona a un agente específico, esto, con el fin de generar grados suficientes de control sobre nuestra vida cognitiva. Si bien esta estrategia es fundamental para distinguir diferentes tipos de estados cognitivos - tales como deliberaciones, razonamientos, juicios, entre otros -, muchos autores han indicado que también es clave para entender experiencias cognitivas psicopatológicas en psicosis. Este artículo revisa (...) la forma en que la estructura subjetiva de los delirios de inserción de pensamiento puede ser utilizada como una estrategia para evaluar los méritos argumentativos de las teorías que intentan explicar la arquitectura y naturaleza de las atribuciones de agencia mental. Luego de evaluar algunos aspectos fundamentales de las dos teorías dominantes en la literatura actual, se sugiere que, a pesar de sus importantes aportes al desarrollo de la discusión, tales enfoques no poseen los recursos explicativos suficientes para lidiar con el desafío propuesto. ABSTRACT An attribution of mental agency is defined as the act of assigning the initiation or authorship of a first personal thought to a specific agent in order to generate sufficient degrees of control over our own cognitive life. Although this strategy is crucial to distinguish different types of cognitive states - such as deliberations, reasonings, judgements, among others -, a number of authors have suggested that it is also crucial to understand psychopathological cognitive experiences in psychosis. This paper explores the way in which the subjective structure of thought insertion can be used as a strategy to evaluate the merits of theories aiming at explaining the nature and architecture of attributions of mental agency. After examining some of the most fundamental aspects of the two dominant theories in current literature, I suggest that, despite the contributions made by such theories to the discussion, none of them is able to face the challenge in a plausible way.

Patients suffering from delusions of thought insertion (TI) report that external agents of different nature have placed thoughts into their minds. The symptom involves distressing feelings of intromission and exposition, loss of mental privacy, diminished ego boundaries, and a – often neglected – peculiar “physicality”. A dominant approach within cognitive sciences characterizes TI as involving alterations in the experience of being the author of certain thoughts. For the advocates of this so-called Standard Approach to TI, the absence of a sense (...) of agency for certain thoughts would lead to their externalization, this explaining the general structure of the clinical reports. In this paper, I problematize the phenomenological picture of everyday thoughts that the standard approach adopts when trying to make sense of TI. I claim that the standard approach neglects two more fundamental aspects of TI, namely the multimodal nature of thinking in psychosis and the deeply social dimension of the phenomenology of delusions in schizophrenia. After this, a broader descriptive phenomenological characterization of TI is provided. Finally, I establish some connections between the characterization of TI developed here and current research in social perception and clinical practice. (shrink)

En filosofía de la mente se ha sugerido que, a diferencia de los estados puramente materiales, los estados conscientes serían aquellos de los cuales podemos decir que existe ‘un algo que es como estar en ellos’ para un sujeto, esto es, estados que poseen una fenomenología. Asumiendo una demarcación intuitiva entre estados sensoriales y estados cognitivos, durante los últimos años se ha establecido un debate en torno a la pregunta acerca del carácter fenoménico de nuestros estados cognitivos, especialmente, el de (...) nuestros pensamientos. A este asunto se le ha denominado el debate acerca de la fenomenología cognitiva. El análisis del debate parece depender del examen crítico de las formas en las que establecemos conclusiones acerca de los componentes fenoménicos de nuestra propia vida mental. El presente artículo elabora diversos problemas que se derivan del uso de dos estrategias en este contexto: reportes introspectivos y los contrastes fenoménicos. Luego de analizar la forma en que tales estrategias podrían favorecer a cierta posición dentro del debate, el artículo concluye comentando cómo algunos asuntos asociados a la fenomenología de la actividad matemática podrían iluminar el debate.

El problema tipológico surge al intentar definir el tipo de estado mental que subyace a los reportes de pacientes delirantes. Este artículo explora dos de los enfoques más populares a este problema en la literatura actual en filosofía de la mente. El análisis concluye que el enfoque doxástico —que conceptualiza los delirios como creencias anormales— es superior en términos conceptuales, empíricos y fenomenológicos al enfoque imaginístico, que caracteriza a los delirios como un tipo de estado mental imaginario. Finalmente, se concluye (...) con algunos de los desafíos que el enfoque necesita resolver para ampliar su alcance y poder explicativo. (shrink)

BackgroundThe Patient Health Questionnaire-9 is the most well-known self-report measure to screen for depressive symptomatology, although discerning which is the factor structure that represents the best fit remains a challenge.ObjectiveThe aim of this study was to analyze the psychometric properties and factorial structure of the Spanish version of the PHQ-9 in a large sample of Ecuadorian college students.MethodsA total of 5,394 students from three Ecuadorian universities were surveyed using a computerized questionnaire within a 4-week assessment period. The PHQ-9 was tested (...) for factorial structure, reliability, and correlations with other mental health-related measures.ResultsThe hierarchical model that included a general factor and three nested factors had a better fit, and such a hierarchical structure remained invariant across sex and age. Total omega value was 0.90 for the total scale and hierarchical omega values were 0.68 for the general factor, as well as 0.34, 0.38, and 0.44 for the respective nested factors. Moreover, PHQ-9 scores were significantly higher among women, although effect sizes of comparison of those sex differences were very small. Finally, the PHQ-9 scores correlated with multiple mental health indicators.DiscussionThe Spanish version of the PHQ-9 showed good psychometric properties among Ecuadorian college students. The hierarchical structure showed the best fit for the data, including not only a dominant general factor, but also the somatic, cognitive/affective and concentration/motor subcomponents. In conclusion, the PHQ-9 tool seems to represent an easy-to-implement screening questionnaire to design preventive programs for those Ecuadorian college students at risk of developing depressive disorders.

Disturbances in social cognition are a core feature of schizophrenia. While most research in the field has focused on emotion perception, social knowledge, theory of mind, and attribution styles, the domain of social perception has received little specific attention. In this paper, we suggest that this issue can be explained by the lack of a precise and unitary definition of the concept, this leads to the existence of different competing uses of the concept and their conflation with other domains of (...) social cognition. Relying on resources coming from the ecological approach to psychology and the phenomenological tradition in psychiatry, we propose that the concept of Social Perception should be used to refer to low-level pre-reflective processes underlying the awareness of interpersonal interactions with and between others. Clinical data suggests that people with schizophrenia have problems perceiving social situations as opportunities for social engagement, so, in order to fulfil this explanatory need, we propose that the term should be used to capture this important—yet neglected—domain of social cognition. We conclude with the discussion of some future directions for research derived from our proposal. (shrink)

An attribution of mental agency is defined as the act of assigning the initiation or authorship of a first personal phenomenal thought to a specific agent. This type of attribution is fundamental for the production of the belief that human beings are rational agents not only in behavioral terms, but also, in a cognitive manner. The top-down approach –one of the dominant theories in current literature– suggests that attributions of mental agency arise as retrospective rational explanations for the occurrence of (...) phenomenal thoughts. Thus, the agency of a thought would not be contained in its most fundamental phenomenal structure, rather, it would be an imposed category. After introducing the most fundamental elements of the debate, this paper evaluates the top-down model in order to identify its argumentative strengths and weaknesses. It is concluded that, although this model possesses a number of merits, it cannot deal in a plausible way with some fundamental conceptual challenges. (shrink)
