Existe gran consenso dentro de la academia en relación a la necesidad de tener en cuenta un gran número de variables para poder conceptualizar y medir la inclusión o, por ende, la exclusión social que viven ciertos colectivos. A través de un estudio en profundidad de la bibliografía, casos piloto y proyectos similares, se ha creado un sistema de indicadores con la finalidad de medir el impacto socioeconómico de una actividad sociodeportiva vinculada a la inclusión de personas con diversidad funcional. (...) El sistema resultante, se aplicarán en el caso piloto VARIED, un proyecto europeo realizado en cinco países de la propia Unión Europea. (shrink)

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

The first European settlements in the new world faced technical issues with the help of the XVI century scientific advances. Besides briefly exposing the scientific and technological situation, this paper explores, with the help of reverse engineering, two singular mechanical wits representative of the technological advances introduced in America to overcome different problems. Firstly, a pump, based on an alternative movement system through crankshafts and pistons used against the continuous flooding suffered in the Ciudad de México valley. Although flooding remained (...) a problem (it was solved in the XX century), hydraulic pumps were essential for continuous soil drainage. Secondly, a port crane for handling cannons, military devices, and construction materials during the Lima fortification in the XVII century. For both cases, reverse engineering, through engineering methods, Computer-Aided Design CAD programs, and additive manufacturing, provides virtual and/or tangible mockups that help to analyze and improve our knowledge about the dimensions, materials, and functions of used (and currently lost) mechanical systems during the American colonization.

Abstract“The Book of Secrets in the Results of Ideas”, usually called “The Book of Secrets” is a codex containing drawings and descriptions of thirty-one artifacts attributed to the engineer Alī Ibn Khalaf al-Murādī, who lived in Andalusia in southern Spain at the beginning of the 11th century. This manuscript is one of the first written testimonies that describe medieval mechanisms with complex precision. The aim of this work is to reconstruct and study from a historical and technological point of view (...) two of the ancient artifacts contained in the “Book of Secrets”, the “Fortress Demolisher” and the “Magic Well”. The “Fortress Demolisher” is a war machine designed to demolish the upper part of the walls or towers and consists of a battering ram mounted on a platform that can be raised several meters above the ground using a scissor mechanism. The “Magic Well” is a mechanism with several pulleys whose purpose is to raise water several meters from the bottom of a well by collecting a small portion of rope. To reconstruct the two artifacts, a digital model and a detailed study of the geometry and operation of the mechanisms, were first carried out. 3D printing, using the Fused Deposition Modelling technology, made the physical reproduction. The digitization and physical reproduction by 3D printing of the mechanisms represent an update of the traditional ways of transmitting knowledge. The use of these new technologies makes the knowledge more accessible, understandable and attractive. (shrink)

Background: Frailty is a common syndrome among older adults and patients with several comorbidities. Grip strength is a representative parameter of frailty because it is a valid indicator of current and long-term physical conditions in the general population and patients with severe mental illnesses. Physical and cognitive capacities of people with SMIs are usually impaired; however, their relationship with frailty or social functioning have not been studied to date. The current study aimed to determine if GS is a valid predictor (...) of changes in cognitive performance and social functioning in patients with type-2 diabetes mellitus and SMIs. Methods: Assessments of social functioning, cognitive performance, and GS were conducted in 30 outpatients with type 2 diabetes mellitus, 35 with major depressive disorder, 42 with bipolar disorder, 30 with schizophrenia, and 28 healthy controls, twice during 1-year, follow-up period. Descriptive analyses were conducted using a one-way analysis of variance for continuous variables and the chi-squared test for categorical variables. Differences between groups for the motor, cognitive, and social variables at T1 and T2 were assessed using a one-way analysis of covariance, with sex and age as co-variates. To test the predictive capacity of GS at baseline to explain the variance in cognitive performance and social functioning at T2, a linear regression analysis was performed. Results: Predictive relationships were found among GS when implicated with clinical, cognitive, and social variables. These relationships explained changes in cognitive performance after one year of follow-up; the variability percentage was 67.7%, in patients with type-2 diabetes mellitus and 89.1% in patients with schizophrenia. Baseline GS along with other variables, also predicted changes in social functioning in major depressive disorder, bipolar disorder, and schizophrenia, with variability percentages of 67.3, 36, and 59%, respectively. Conclusion: GS combined with other variables significantly predicted changes in cognitive performance and social functioning in people with SMIs or type-2 diabetes mellitus. Interventions aimed to improve the overall physical conditions of patients who have poor GS could be a therapeutic option that confers positive effects on cognitive performance and social functioning.

RESUMEN. Aunque pocos comentarios repararan en ella, la pregunta por la conciencia y su relación con el mundo moral está presente en Murdoch desde sus primeros escritos y reaparece con fuerza en Metaphysics as a guide to morals. La crítica moderna de la metafísica, y de la idea cartesiana de alma como sustancia, nos deja sin imágenes metafísicas para la concepción de sentido común del yo individual como un centro moral. ¿Cómo pensarla e imaginarla ahora? El existencialismo francés y el (...) conductismo lingüístico británico, Sartre y Hare, comparten una imagen del hombre y de la moral que resitúa ese centro en una voluntad que se ejerce discontinuamente, a saltos, dejando en la sombra tanto el campo de los pensamientos como el de los valores. Murdoch se enfrenta a tales posiciones con una trama de conceptos alternativa: el mundo que habitamos los agentes morales contiene ya siempre los valores que introduce en ellos el sujeto moral a través de una conversación interna continua que depende de la atención que prestamos a unas cosas u otras, al ego o a la realidad que lo trasciende. Proponemos finalmente una fusión de horizontes entre Heidegger, Weil y Murdoch que incluye también los conceptos de amor y bien. (shrink)

Este artículo realiza un análisis léxico-semántico de la terminología irreligiosa en la literatura griega. Se ha seleccionado un término clave y un autor relevante a fin de ilustrar la importancia del fenómeno irreligioso en la sociedad de Época Clásica. El adjetivo ὅσιος describe el respeto religioso en acciones y actitudes hacia las divinidades y también hacia otros seres humanos. Sófocles usa la forma privativa ἀνόσιος en contextos donde falta ese respeto religioso, con consecuencias negativas para la polis.

In spite of the advances in our knowledge of cancer biology, most cancers remain not curable with present therapies. Current treatments consider cancer as resulting from uncontrolled proliferation and are non‐specific. Although they can reduce tumour burden, relapse occurs in most cases. This was long attributed to incomplete tumour elimination, but recent developments indicate that different types of cells contribute to the tumour structure, and that the tumour's cellular organization would be analogous to that of a normal tissue, with a (...) main mass of differentiating cells sensitive to anti proliferative agents, together with a small percentage of quiescent, resistant stem cells responsible for replenishing the tumour: the Cancer Stem Cells (CSCs). Anti‐CSCs targeted therapeutic agents would prevent tumour regeneration. New mouse models tailored to exploit this novel concept will be critical to develop CSC‐based anti‐cancer therapies. Here we review the biological basis and the therapeutic implications of the stem‐cell model of cancer. BioEssays 29:1269–1280, 2007. © 2007 Wiley Periodicals, Inc. (shrink)

BackgroundImplementing the routine consultation of patient advance directives in hospital emergency departments and emergency medical services has become essential, given that advance directives constitute the frame of reference for care personalisation and respect for patients’ values and preferences related to healthcare. The aim of this study was to assess the levels and relationship of knowledge and attitudes of nursing and medical professionals towards advance directives in hospital emergency departments and emergency medical services, and to determine the correlated and predictor variables (...) of favourable attitudes towards advance directives.MethodsObservational, descriptive, and cross-sectional study. The study was conducted in the emergency department of a second-level hospital and in the emergency medical service. Data collection was performed from January 2019 to February 2020. The STROBE guidelines were followed for the preparation of the study.ResultsA total of 173 healthcare professionals responded to the questionnaire. Among them, 91.3% considered that they were not sufficiently informed about advance directives, and 74% acknowledged not having incorporated them into their usual practice. Multinomial analysis indicated a statistically significant relationship between the variable emergency medical service and having more favourable attitudes towards consulting the advance directives in their practical application (OR 2.49 [95% CI 1.06–5.88]; p = 0.037) and compliance in complex scenarios (OR 3.65 [95% CI 1.58 − 8.41]; p = 0.002). Working the afternoon and night shift was a predictor variable for obtaining a higher score with respect to attitudes in complex scenarios.ConclusionThere is an association between the level of knowledge that nursing and medical professionals have about advance directives and the scores obtained on the attitude scales at the time of practical implementation and in complex scenarios. This shows that the more knowledge professionals have, the more likely they are to consult patients' advance directives and to respect their wishes and preferences for care and/or treatment.

The SRL vs. ERL theory has shown that the combination of levels of student self-regulation and regulation from the teaching context produces linear effects on achievement emotions and coping strategies. However, a similar effect on stress factors and symptoms of university students has not yet been demonstrated. The aim of this study was to test this prediction. It was hypothesized that the level of student self-regulation (low/medium/high), in interaction with the level of external regulation from teaching (low/medium/high), would also produce (...) a linear effect on stress factors and symptoms of university students. A total of 527 undergraduate students completed validated questionnaires about self-regulation, regulatory teaching, stress factors and symptoms. Using an ex post facto design by selection, ANOVAs and MANOVAs (3 x 3; 5 x 1; 5 x 2) were carried out. The results confirmed that the level of self-regulation and the level of regulatory teaching jointly determined the level of stress factors and symptoms of university students. Once again, a five-level heuristic of possible combinations was configured to jointly determined university students’ level of academic stress. We concluded that the combination of different levels of student regulation levels and regulation from teaching process jointly determines university students’ level of academic stress. The implications for university students’ emotional health, stress prevention and well-being are established. (shrink)

The aim of this research was to establish linear relations (association and prediction) and inferential relations between three constructs at different levels of psychological research –executive dysfunction(microanalysis),self-regulation(molecular level), andself-vs.external regulation(molar level), in the prediction of emotion regulation difficulties. We hypothesized that personal and contextual regulatory factors would be negatively related to levels of executive dysfunction and emotion regulation difficulties; by way of complement, non-regulatory and dysregulatory personal, and contextual factors would be positively related to these same difficulties. To establish relationships, (...) we used a retrospective,ex postfacto design, where 298 university students voluntarily participated by completing standardized self-reports. Linear and structural correlational, predictive analyses were performed, as well as inferential analyses. Results were consistent and validated the proposed hypotheses, for both association and prediction. The most important result refers to the discriminant value of the five-level combination heuristic for predicting Executive Function and External (contextual) Dys-Regulation. In conclusion: (1) both personal and contextual regulation factors must be analyzed in order to better understand the variation in executive functions and emotion regulation difficulties; (2) it is important to continue connecting the different levels of the constructs referring to self-regulation, given their complementary role in the behavioral analysis of regulation difficulties.

This study analyzes the interests of Spanish audiences in travel magazines within the current context of press consumption. The objectives are to identify the readers' reading frequency and reasons for reading, what contents interest them, and what aspects of the photographs attract them. The methodology involves a structured questionnaire completed by a representative sample of the Spanish population (n=1000). The main results reveal a low reading frequency, great interest in practical information, preference for landscape photography (over the age of 54) (...) and nightlife photography (young people), and indifference regarding the journalistic source of the images. These data provide relevant information on which to adapt travel magazines' content strategy. (shrink)

The self- vs. external-regulation behavior theory, SR-ER Theory model has postulated the Self-Regulation /Non or De-Regulation/Dys-regulation continuum in the person and in their context. The model also generates a behavioral heuristic that allows us to predict and explain the variability of other dependent behavioral variables in a range of scenarios. Consequently, the objective of this study was to validate the different scales prepared on the basis of the theory presented. A total of 469 students voluntarily completed at different times the (...) five questionnaires presented, to give a total of 1,385 completed questionnaires. Using an ex post facto design, descriptive, correlational, confirmatory factorial analysis, reliability, and concurrent validity analyses were carried out. The scales were analyzed individually and as a whole. The results showed the acceptable structure of scale and consistent levels of reliability. The five levels generated by the SR-NR-DR combinatory heuristic that arises from the theoretical model determined significant differences in the levels of the variables analyzed for each psychological context. We discuss the theoretical implications and the implications for the assessment and improvement of the behaviors analyzed in function of the personal and contextual regulation levels evaluated.

Since the mid-20th century, the study of Self-Regulated Learning has aimed to identify the distinctive characteristics that enable individuals to acquire new knowledge and skills under their control. The theory of Internal Self-Regulation vs. External-Regulation in Learning has postulated that a large number of self-regulatory variables are mediated by regulated/non-regulated or dysregulated features of the context. After signing their informed consent, a total of 616 university students completed validated instruments of SRL vs. ERL, behavioral regulation, regulatory teaching, and metacognitive study (...) control strategies. Using an ex-post facto design and correlation, regression, structural equation model and mediation analyses, the present research aimed to establish multicausal predictive relationships among the analyzed variables. Results indicated positive predictive effects between the external regulation variables on the self-regulation variables in learning [regulation /non-regulation /dysregulation ]; as well as positive predictive effects between SRL on SRB, RT and metacognitive SRS. Additionally, external regulation not only predicted but mediated numerous relations among the variables studied. Other findings and important considerations for future research in the field of self-regulation are discussed. (shrink)

Physical activity, body composition and sedentary behavior may affect the health of children. Therefore, this study examined the effect of an educational hybrid physical education program on physical fitness, body composition and sedentary and PA times in adolescents. A 9-month group-randomized controlled trial was conducted in 150 participants allocated into the control group and experimental group. Cardiorespiratory fitness, speed, strength, agility, flexibility and body mass index were assessed through previously validated field tests. Sedentary time, PA at school and afterschool were (...) evaluated with the Youth Activity Profile-Spain questionnaire. Significant differences were observed concerning to the CG in APA-weekend, speed-agility and agility. Regarding the intervention, cardiorespiratory fitness, speed-agility, strength, flexibility, agility, PA in school, APA-weekday, APA-weekend, APA-week, and sedentary time increased significantly in the EG. The use of a hybrid program based on teaching personal and social responsibility and gamification strategies produced enhancements in cardiorespiratory fitness, agility, speed, APA-weekdays and APA-weekends, reducing the sedentary time.

The question of whether the entrepreneur is born or made, forces us to respond that the entrepreneurial culture clearly breaks with the myth that entrepreneurs are born. Currently, it is considered that entrepreneurial skills can be acquired like any other discipline and that is why it should be taught. Their teaching and learning are key to the well-being of the teacher and to the positive achievement of the students. The entrepreneurial culture is an educational objective of developed societies and has (...) its origin in the business culture. There are two current models, American and European. The one that develops in the Extremadura region, based on the European model, tries to create a vital state in the participating students that enhances competences such as creativity, personal initiative or self-confidence, elements that try to generate a true motivation to undertake. The motivated, accomplished and positive teacher contributes to that achievement and achieving it favors the well-being of teachers. It’s a round trip. It is a “do ut des.” In our research, we evaluated four entrepreneurial culture programs in the classroom: “Junioremprende,” “Teenemprende,” “Experemprende,” and “Youthemprende.” The teachers involved in the programs are 356, and the valid questionnaires are 154. The students enrolled in the programs are 4800, and the questionnaires valid 1198. In the questionnaire, one of the key questions is “general teacher satisfaction,” with 17 common questions for all the programs. An essential question posed is: “I am satisfied with the achievements obtained by my students to participate in the program” The results of our research, according to a seven-point Likert scale, gives a very high degree of teachers’ satisfaction. Their satisfaction was centered on the perception of their teachings are conducive to the achievement of his students. The degree of teacher satisfaction for each of the programs and significantly means differences were found with Junior program resulted the more satisfied for teachers. For students, participation in the programs resulted in high development of entrepreneurial competencies. Similarly to teachers results, Junior program was found more significant in developing students’ entrepreneurial competencies indicating that entrepreneurial education is very appropriate for children. Findings of this study suggest that entrepreneurial education should be encouraged for students at every stage of education. (shrink)

As a continuation of the work of the third author in [5], we make further observations on the features of Galois cohomology in the general model theoretic context. We make explicit the connection between forms of definable groups and first cohomology sets with coefficients in a suitable automorphism group. We then use a method of twisting cohomology (inspired by Serre’s algebraic twisting) to describe arbitrary fibres in cohomology sequences—yielding a useful “finiteness” result on cohomology sets. Applied to the special case (...) of differential fields and Kolchin’s constrained cohomology, we complete results from [3] by proving that the first constrained cohomology set of a differential algebraic group over a bounded, differentially large, field is countable.

There is an ongoing debate about the meaning of lexical words, i.e., words that contribute with content to the meaning of sentences. This debate has coincided with a renewal in the study of polysemy, which has taken place in the psycholinguistics camp mainly. There is already a fruitful interbreeding between two lines of research: the theoretical study of lexical word meaning, on the one hand, and the models of polysemy psycholinguists present, on the other. In this paper I aim at (...) deepening on this ongoing interbreeding, examine what is said about polysemy, particularly in the psycholinguistics literature, and then show how what we seem to know about the representation and storage of polysemous senses affects the models that we have about lexical word meaning.

Let ‘semantic relevance’ be the thesis that the wide semantic properties of representational mental states (like beliefs and desires) are causally relevant to behavior. A popular way of arguing for semantic relevance runs as follows: start with a sufficient counterfactual condition for causal or explanatory relevance, and show that wide semantic properties meet it with respect to behavior (e.g., Loewer & Lepore (1987,1989), Rescorla (2014), Yablo (2003)).This paper discusses an in‐principle limitation of this strategy: even the most sophisticated counterfactual criteria (...) systematically misclassify irrelevant properties as relevant when they stand in certain kinds of modal co‐variation or ‘entanglement’ relations to genuinely relevant properties. This entanglement problem, I argue, is more general and more serious than proponents of the counterfactual strategy have recognized: it threatens recent interventionist arguments for semantic relevance, and is not easily solved by appeal to proportionality or naturalness. I end by suggesting that proponents of semantic relevance may need to shift their attention from patterns of counterfactuals to the lawful psychological generalizations that explain them. (shrink)

En este artículo se analiza un conjunto de obras sobre ríos y represas que pertenece a la serie titulada Represa /Represión (2012-) de la artista colombiana Carolina Caycedo. La pregunta de la que se ocupa esta investigación es ¿cómo las estrategias estéticas de estas obras identifican los problemas socio-ecológicos generados por las represas y contribuyen a articular imaginarios políticos de sostenibilidad? El argumento principal es que las obras de Caycedo sobre el río Yuma o Magdalena contribuyen con la construcción de (...) una memoria histórica ambiental, a partir de saberes populares, campesinos y cosmovisiones indígenas. Con este fin, este texto caracteriza el problema de las represas a partir de los conceptos de ‘extractivismo’, de Macarena Gómez-Barris, y ‘desterritorialización’, de Rob Nixon, para luego realizar un recorrido por las obras de la artista, de cuyo análisis se va construyendo una caracterización de la memoria histórica ambiental de un segmento del río Yuma. El marco conceptual del trabajo incluye las nociones de ‘seres-tierra’, de Marisol de la Cadena y ‘territorio’, de Arturo Escobar, así como ‘memoria de los ríos’, de Kristina Lyons. La metodología se basa en el análisis conceptual y técnico de las piezas de Caycedo en el marco interdisciplinar de las humanidades ambientales. El análisis concluye que las obras de Caycedo generan espacios de memoria histórica ambiental desde perspectivas trasnacionales y, en estos espacios de encuentro que constituyen las obras, se relacionan y rearticulan los extremos de falsos antagonismos como naturaleza/cultura, humano/no humano y ciencia/arte.

This article focuses on Stuart Hall’s reading of Louis Althusser’s main theoretical works. Since the early 1970s, Hall has undertaken a critical confrontation with Althusser’s ‘structural Marxism’, rescuing those useful concepts to think cultural difference and identity, without failing to criticize his ‘superstructuralist’ interpretation of Marx. However, what Hall will retain as Althusser’s most important contribution is, above all, his theory of ideology. In this context, I follow an idea formulated by Hall that could be read as summarizing the theoretical (...) and political scope of Althusser’s contribution to Cultural Studies: ‘he enabled me to live in and with difference’. By complicating classical interpretations schemes in the Marxist tradition, Hall’s Althusser may be read as a ‘thinker of difference’ who opens up a whole research program to reconsider class conflicts as traversed (or ‘overdetermined’) by gender, racial or colonial conflicts.

The present paper tries to answer the question Is religious education compatible with the purposes of liberal education? This work argues that it is possible, and desirable, that democratic states built on liberal ideals include religious education in all schools since increasing the number of options among which the future citizen may choose the conception of the good with which he or she wishes to live is a condition for autonomy as one of its educational purposes. However, the proposal is (...) not based on religious confessional education, which by itself does not satisfy the liberal educational goals, but is redefined from the common principles compatible both religious confessions and non-religious views of morality and citizenship.

Teaching mathematics and improving mathematics competence are pending subjects within our educational system. The PEIM (Programa Evolutivo Instruccional para Matemáticas), a constructivist intervention program for the improvement of mathematical performance, affects the different agents involved in math learning, guaranteeing a significant improvement in students’ performance. The program is based on the following pillars: (a) students become the main agents of their learning by constructing their own knowledge; (b) the teacher must be the guide to facilitate and guarantee such a construction (...) by being a great connoisseur of the fundamental aspects of the development of the child’s mathematical thinking; (c) the mathematical contents must be sequenced in terms of the complexity and significance for the student as well as contextualized at all times; and (d) the classroom must have a constructivist climate highlighting cooperative work among students. The implementation of PEIM along with the empirical evaluation conducted in several centers in Madrid and Zaragoza (Spain) confirm how students improve their mathematical competence. Both first- and second-grade students in elementary education were far more effective in solving problems, highlighting the use of more advanced strategies in their resolution and a lower incidence of conceptual errors. Moreover, it was possible to verify how the students proving greater difficulty, experienced an evolution in learning similarly to those who did not present it. The program provides customized education to allow the teacher to know at all times how he should be more influential on the students’ learning through mathematical profiles. Both teaching practice and teachers were observed, being that of the experimental group more prone to analyzing processes and allowing the construction of knowledge by students, due to their psycho-developmental training. As a result, we found several improvements through the implementation of the program that may serve, for upcoming years, as a basis for the necessary changes in the teaching of mathematics. (shrink)

This paper presents a pilot study that explores instances of objectless awareness during sleep: conscious experiences had during sleep that prima facie lack an object of awareness. This state of objectless awareness during sleep has been widely described by Indian contemplative traditions and has been characterised as a state of consciousness-as-such; while in it, there is nothing to be aware of, one is _merely_ conscious (cf. Evans-Wentz, 1960 ; Fremantle, 2001 ; Ponlop, 2006 ). While this phenomenon has received different (...) names in the literature, such as ‘witnessing-sleep’ and ‘clear light sleep’ among others, the specific phenomenological profile of this state has not yet been rigorously studied. This paper aims at presenting a preliminary investigation of objectless consciousness during sleep using a novel tool in qualitative research that can guide future research. Five participants experiencing objectless consciousness during sleep were interviewed following the _Micro-phenomenological Interview_ technique (MPI; Petitmengin, 2005, 2006 ). All participants reported an experience they had during sleep in which there was no scenery and no dream. This period labelled as ‘No Scenery/Void’ was either preceded by the dissolution of a lucid dream or by other forms of conscious mentation. The analysis of the results advances four experiential dimensions during this state of void, namely (1) Perception of absence, (2) Self-perception, (3) Perception of emotions, and (4) Perception of awareness. While the results are primarily explorative, they refer to themes found in the literature to describe objectless sleep and point at potential avenues of research. The results from this study are taken as indications to guide future operationalisations of this phenomenon. (shrink)
