Abstract Recently, in philosophy, what has been attractive about boredom has been the negative effects it can have on the people who experience it. In this article, contrary to this perspective, we deal with what boredom is and if there can be positive effects. As a starting point, we consider boredom to be an unpleasant affective experience. Given this characteristic of boredom, this affective experience motivates the subject who experiences it to look for ways to eliminate it. After this characterization of boredom, we argue that it not only motivates negative activities to eliminate it, but also positive activities. One of these positive activities is leisure. Regarding leisure, we developed the idea that it is an activity that promotes pleasant affective experiences and is a good candidate for mitigating boredom, since it allows the transition from an unpleasant affective experience to other pleasant ones. Contrary to what is normally thought about leisure as a harmful activity, in this article we intend to show that this is a positive activity for those who carry it out.The way in which leisure is beneficial is that it can contribute to the cultivation of certain virtues and, in this way, to the flourishing of people.

Resumen Recientemente, en filosofía, aquello que ha sido atractivo respecto al aburrimiento han sido los efectos negativos que puede haber en las personas que lo experimentan. En este artículo, contrario a esta perspectiva, nos ocupamos de qué es el aburrimiento y si puede haber efectos positivos. Como punto de partida, consideramos que el aburrimiento es una experiencia afectiva desagradable. Dada esta característica del aburrimiento, esta experiencia afectiva motiva al sujeto que la experimenta a buscar maneras para mitigarla. Después de esta caracterización del aburrimiento, argumentamos que no solamente motiva a realizar actividades negativas para mitigarlo, sino también a actividades positivas. Una de estas actividades positivas es el ocio. Respecto al ocio desarrollamos la idea de que es una actividad que promueve experiencias afectivas agradables y es un buen candidato para mitigar el aburrimiento, ya que permite el paso de una experiencia afectiva desagradable a otras agradables. Contrario a lo que normalmente se piensa sobre el ocio como una actividad nociva, en este artículo pretendemos mostrar que esta es una actividad positiva para quien la realiza. La manera en la que el ocio es benéfico es que puede contribuir al cultivo de ciertas virtudes y, de esta manera, al florecimiento de las personas.

ABSTRACT The aim of this work was to improve the understanding about the relationship between solar radiation and temperature exposure during crop and tomato fruit susceptibility to postharvest chilling injury. Two preharvest treatments were applied: direct sunlight exposed plants (Ex) and shaded plants (Sh). After harvest, fruit were stored at 10⁰C and 4⁰C for ten days. Then, fruit were removed from the chambers and stored at room temperature for four days. Several determinations were carried out: total mineral and calcium content, fruit quality and postharvest parameters, ions leakage and thiobarbituric acid reactive species content and chilling injury index (CII). Ex fruit had higher values of chilling injury index than the Sh fruit, and at the same time, fruit under 4⁰C storage treatment presented a more marked damage than those stored at 10⁰C, demonstrating that accumulated radiation in the field, as a result of a higher solar radiation exposure, is a critical factor affecting postharvest chilling injury susceptibility. The lower calcium content in the Ex fruit could be one of the causes of their response to chilling.

RESUMO O objetivo deste trabalho foi melhorar o entendimento sobre a relação entre a radiação solar e a exposição à temperatura durante a colheita e a suscetibilidade dos frutos de tomate a danos pós-colheita por frio. Foram aplicados dois tratamentos pré-colheita: plantas expostas à luz solar direta (Ex) e plantas sombreadas (Sh). Após a colheita, os frutos foram armazenados a 10⁰C e 4⁰C por dez dias. Em seguida, os frutos foram retirados das câmaras e armazenados em temperatura ambiente por quatro dias. Foram determinados: teor de minerais totais e cálcio, qualidade do fruto e parâmetros pós-colheita, vazamento de íons e teor de espécies reativas ao ácido tiobarbitúrico e índice de injúria pelo frio (CII). Os frutos Ex apresentaram maiores valores de índice de injúria pelo frio do que os frutos Sh e, ao mesmo tempo, os frutos sob tratamento de armazenamento a 4⁰C apresentaram danos mais acentuados do que aqueles armazenados a 10⁰C, demonstrando que a radiação acumulada no campo, como resultado de uma maior exposição à radiação solar é um fator crítico que afeta a suscetibilidade a danos causados pelo frio pós-colheita. O menor teor de cálcio nos frutos Ex pode ser uma das causas de sua resposta ao frio.

Abstract Objective: to analyze from the neighborhood concept, the habitant’s cohesive dynamics in four neighborhoods in Monterrey, taking into account their bonds, practices, values, space, and sense of belonging to a territory. Methodology: it is qualitative and includes interviews and participatory maps through which the object of study’s narrative was built. These neighborhoods’ habitants were the central axis. Results: a) the social cohesion that lasts the most is the one which has strong social and territorial bases; b) this type of neighborhood cohesion is maintained and updated trough collective innovations and actions. Limitations: due to the nature of its objectives, the study did not take into account youth groups’ current actions nor their actual influences. Value: this is one of the few academic studies about the first Monterrey’s working-class neighborhoods that highlights neighborhood cohesion from a mixed geographic and social perspective. Conclusions: it is demonstrated that the social cohesion that lasts the longest is the one that is firmly based on socio-territorial bases, and that neighborhood cohesion rests on social innovations and collective actions.

Resumen Objetivo: analizar, bajo el concepto de barrio, las dinámicas cohesivas de los habitantes de cuatro colonias de Monterrey, considerando sus vínculos, sus prácticas, sus valores, su espacio y la pertenencia a un territorio. Metodología: es cualitativa e incluye entrevistas y mapas participativos mediante los cuales se construyó la narrativa del objeto de estudio. Los habitantes de las colonias seleccionadas son el eje central. Resultados: a) la cohesión social que tiene mayor duración es aquella con fuertes bases socioterritoriales; b) este tipo de cohesión barrial se mantiene y se actualiza mediante innovaciones sociales y acciones colectivas. Limitaciones: por la naturaleza de sus objetivos, el estudio no contempló la acción ni la influencia actual de los jóvenes. Valor: este es uno de los pocos trabajos sobre los primeros barrios obreros de Monterrey que destaca la cohesión barrial desde una perspectiva mixta, es decir, geográfica y social. Conclusiones: se demuestra que la cohesión social que tiene mayor duración es aquella que se sustenta con firmeza sobre bases socioterritoriales y que la cohesión barrial descansa en innovaciones sociales y acciones colectivas.

Abstract: The San Luis Potosí plateau is located in the northern portion of the state; it comprises 15 municipalities with a territorial extension of 28122 km 2 . This area includes the municipalities of Cedral, Matehuala and Villa de la Paz, which stand out for their economic development throughout history. Such is the case of trade that has made of Matehuala an important regional distribution center, supplemented by agricultural activities as key elements of the economy of the municipality of El Cedral, and mining, which in the colonial collection of some relevance in Villa of Peace, where copper is mined, lead, silver and gold. The incorporation of new territories to tourism, as part of a national policy, has allowed the economic diversification in arid zones of Mexico. These municipalities have natural and cultural resources that are suitable for tourism development, based on their physical-geographical attributes, the cultural heritage from pre-hispanic groups, architecture and gastronomy. The failure to recognize these natural and cultural resources, as well as the little interest in tourism development on the part of local governments and local inhabitants, has restrained the diversification of this activity. Therefore, the objective of this research is to evaluate the tourism resources available in these municipalities based on the multicriteria evaluation methodology. This methodology comprises a set of techniques which allow estimating various alternatives based on various criteria and priorities, and assessing those sites with the greatest tourism development potential, as well as the intrinsic characteristics of the activity, such as accessibility, equipment and infrastructure, for the identification of tourist attractions. Interviews were carried out with the governments of the municipalities involved, the Ministry of Tourism of the State of San Luis Potosi, and with the different social stakeholders of the localities studied. As a result of this methodological process, 10 areas with tourism potential were identified based on the detection of suitable sites, to be included in a tourist corridor that would include the most important attributes of the region, where there is an emerging tourism potential that would boost the local and regional tourist economy. In this sense, it can be stated that tourism will be beneficial for the municipalities to the extent that it meets the needs of tourists, is economically profitable, socially fair for the local community and environmentally friendly. The proposal of the corridor, in the planning stage, incorporates environmental, social and economic aspects and implications that foster the mobilization of goods, services, merchandise and tourists in the area, and promote the political integration and the participation of the stakeholders involved.

Resumen: La conformación económica del árido Altiplano de San Luis Potosí ha descansado en los sectores agropecuario, el comercio y la minería. Sin embargo, la incorporación de nuevos territorios a la actividad turística, como parte de una política de impulso nacional, ha permitido la apertura a la diversificación económica en zonas desérticas. En este sentido, los municipios de Cedral, Matehuala y Villa de la Paz disponen de recursos naturales y culturales para el aprovechamiento turístico, lo que se sustenta en los atributos de su medio físico-geográfico, la herencia cultural de grupos prehispánicos, su arquitectura y su gastronomía. Esta investigación revela la riqueza material y cultural de tres municipios del Altiplano potosino en la que se utilizó una metodología de análisis multicriterio para definir 10 áreas proclives al aprovechamiento turístico con base en la detección de sitios aptos y, a partir de estos, conformar un corredor turístico con los atributos más importantes de la región, en la que existe un emergente potencial que dinamizaría la economía turística local y regional. La propuesta del corredor –dentro de su planeación– integra condiciones (y tiene implicaciones) de orden ambiental, social y económico, que incentivan la movilización de bienes, servicios, mercancías y turistas en la zona y promueven la integración política y la participación de los actores involucrados.

To determine viable anatomical landmarks allowing for accurate femoral and tibial tunnel placement in anatomical position during posterior cruciate ligament (PCL) reconstruction. Ten knees were dissected to analyze femoral and tibial PCL insertion measurements and the features specific to the PCL and its fascicles. The clock hands system was used to measure femoral insertions. The meniscus and anterior cruciate ligament (ACL) were used as landmarks to measure tibial insertions. The PCL and its corresponding fascicle characteristics were determined by its femoral insertion, central portion and tibial insertion. The mean lengths between the central point of the PCL footprint and the articular cartilage border at 12:00 h were 17.23 mm (±3.94) and 17.73 mm (±4.11) for the right and left knees, respectively. The anterior-posterior mean lengths for the PCL were 11.94 mm (±5.08) between the posterior PCL border and the anterior PCL border. The mean lengths were 33.52 mm (±3.49) from the medial border of the lateral meniscus to the lateral PCL border and 32.24 mm (±2.28) from the medial border of the medial meniscus to the medial PCL border. From the anteroposterior viewpoint, the anterolateral fascicle is greater than the posteromedial one in its femoral and tibial insertions and in its central portion. A quantitative data collection summary was conducted with different PCL variables, along with its fascicles and their various femoral and tibial bony landmarks. Various measurements were obtained, indicating the high functionality shared by the PCL fascicles. Lengths reported for insertions are practical landmarks for the locations of femoral and tibial tunnels during posterior cruciate ligament plasty. We must take into account native PCL form to avoid oversizing the graft during reconstruction and to avoid a possible clamping of the graft with the surrounding structures.

El propósito del estudio fue determinar referencias anatómicas viables para la correcta colocación de los túneles femorales y tibiales en posición anatómica durante la reconstrucción del ligamento cruzado posterior (LCP). Se utilizaron 10 rodillas, las cuales fueron disecadas para analizar las mediciones de la inserción femoral y tibial del LCP, sus fascículos y estructuras adyacentes. Se utilizó el sistema de las manecillas del reloj para la medición de las inserciones femorales. Los meniscos y el ligamento cruzado anterior (LCA) fueron utilizados como referencias para la medición de las inserciones tibiales. El LCP y las características de sus fascículos correspondientes fueron determinados por su inserción femoral, porción central e inserción tibial. La media de la longitud entre la porción central de la huella dejada por el LCP y el margen anterior del cartílago femoral a las 12:00 h fue de (±3.94) y 17,73 mm (±4,11) para la rodilla derecha e izquierda, respectivamente. La longitudes del LCP fueron de 11,94 mm (±5,08) entre el margen posterior del LCP y el margen anterior del LCP. La media fue de 33,52 mm (±3,49) desde el margen medial del menisco lateral al margen lateral del LCP y de 32,24 mm (±2,28) del margen medial del menisco medial al margen medial del LCP. Desde el punto de visión anteroposterior, el fascículo anterolateral es mayor que el posteromedial tanto en su inserción femoral como en el punto central e inserción tibial. Se analizó una colección cuantitativa de bases de datos con distintas variables del LCP, así como de sus fascículos y sus inserciones femorales y tibiales. Se obtuvieron varias medidas, indicando la alta funcionalidad compartida por los fascículos del LCP. Las inserciones reportadas son referencias prácticas para la localización de los túneles tibiales y femorales durante la plastía del ligamento cruzado posterior.

Resumen El objetivo de este trabajo es presentar la cronología y las principales tendencias de los análisis geoarqueológicos, zooarqueológicos, de la tecnología lítica y de los entierros humanos recuperados en el sitio arqueológico Zoko Andi 1 (Pdo. de Patagones). Éste se localiza en una duna, sobre la margen derecha del curso inferior del río Colorado. Se obtuvieron nueve fechados radiocarbónicos provenientes de especímenes faunísticos, restos óseos humanos y carbón que ubican la cronología del sitio entre ca. 1500-400 años AP. Las dataciones obtenidas, en conjunción con los aspectos estratigráficos identificados, indican la existencia de al menos dos lapsos de ocupación. El primero de ellos se ubica en torno a los ca. 1500-1300 años AP (Holoceno tardío inicial), mientras que el otro se localiza en ca. 800-400 años AP (Holoceno tardío final). En este sentido, se trata del primer sitio del área en cuya secuencia se distinguen dos componentes que se corresponden con los dos bloques temporales del Holoceno tardío. Los resultados obtenidos hasta el momento en las distintas líneas de análisis se ajustan parcialmente a las tendencias propuestas en los modelos formulados para el área y son brevemente discutidas en este trabajo.

Abstract The objective of this paper is to present the chronology and the main trends obtained from the results of geoarchaeology, zooarchaeology, lithics and human burials of Zoko Andi 1 archaeological site (Patagones district, Buenos Aires province). The site is located in a dune, on the right bank of the lower basin of the Colorado River. Nine radiocarbon dates from faunal remains, human bones and charcoal place the chronology of the site at ca. 1500-400 years BP. The chronology obtained in conjunction with stratigraphic aspects of the site indicates the existence of at least two components: the lower is located around ca. 1500-1300 years BP (Initial Late Holocene), while the upper is placed at ca. 800-400 years BP (Final Late Holocene). In this sense, Zoko Andi 1 is the first site of the area that exhibits two clearly distinguishable components, each one corresponding to the distinct temporal periods proposed for the Late Holocene. The results obtained for the analyzed lines of evidence are partially consistent with the trends of the models developed for the area, which are briefly discussed in this paper.
