From sensorimotor dependencies to perceptual practices: making enactivism social
Proponents of enactivism should be interested in exploring what notion of action best captures the type of action-perception link that the view proposes, such that it covers all the aspects in which our doings constitute and are constituted by our perceiving. This article proposes and defends the thesis that the notion of sensorimotor dependencies is insufficient to account for the reality of human perception, and that the central enactive notion should be that of perceptual practices. Sensorimotor enactivism is insufficient because it has no traction on socially dependent perceptions, which are essential to the role and significance of perception in our lives. Since the social dimension is a central desideratum in a theory of human perception, enactivism needs a notion that accounts for such an aspect. This article sketches the main features of the Wittgenstein-inspired notion of perceptual practices as the central notion to understand perception. Perception, I claim, is properly understood as woven into a type of social practices that includes food, dance, dress, music, etc. More specifically, perceptual practices are the enactment of culturally structured, normatively rich techniques of commerce of meaningful multi- and inter-modal perceptible material. I argue that perceptual practices explain three central features of socially dependent perception: attentional focus, aspects’ saliency, and modal-specific harmony-like relations
The Performance Evolution of Match Play Styles in the Spanish Professional Basketball League
The aim of this study is to analyse the performance evolution of all, and the dominant, team’s performances throughout an eight-season period within the Spanish professional basketball league. Match-related statistics were gathered from all regular season matches (n = 2426) played during the period 2009−2010 to 2016−2017. The non-metric multidimensional scaling model was used to examine the team’s profiles across seasons and for the most successful (playoff) teams. The main results showed that: 3-point field goals made (effect size, d = 0.61; 90% confidence interval, CI = 0.23; 1.37) and missed (d = 0.72; 90% CI = 0.35; 1.46), and assists (d = 1.27; 90% CI = 0.82; 1.86) presented a positive trend with an increased number of actions across the seasons; 2-point field goals made (d = 0.21; 90% CI = −1.25; 2.02) and missed (d = 0.27; 90% CI = −0.52; 0.92) were decreased; free throws made and missed, rebounds, fouls, blocks, steals and turnovers showed a relatively stable performance. The matrix solution (stress = 0.22, rmse (root mean squared error) = 7.9 × 104, maximum residual = 5.8 × 103) indicated minimal season-to-season evolution with the ordination plot and convex hulls overlapping. The two most dominant teams exhibited unique match patterns with the most successful team’s pattern, a potential benchmark for others who exhibited more dynamic evolutions (and less success). The current findings identified the different performances of teams within the Spanish professional basketball league over eight seasons with further statistical modelling of match play performances useful to identify temporal trends and support coaches with training and competition preparations
Instituciones locales y proceso de urbanización en Tultepec
Proyecto Terminal (Licenciatura en Sociología) - Universidad Autónoma Metropolitana, Unidad Azcapotzalco, División de Ciencias Sociales y Humanidades, Departamento de Sociología, Área de Sociología Urbana, 1992. 1 archivo PDF (109 páginas)Se desarrolla un análisis sobre el impacto que el proceso de urbanización del Área Metropolitana de la Ciudad de México ha tenido en las instituciones locales de Tultepec Estado de México. En el primer capítulo se hace una revisión histórica sobre el origen del poblado, desde los primeros grupos étnicos prehispánicos que se asentaron en él, la influencia que tuvo en Tultepec la llegada de los españoles y los procesos urbanos actuales, con el fin de entender más a fondo a la institución y a las prácticas tradicionales que surgieron en la época colonial y que en la actualidad se siguen conservando. En el capítulo se analizan las características principales de la institución local tradicional: La Mayordomía, su significado, su forma de organización, sus funciones y la forma como se articula con las prácticas económicas y artísticas: la pirotecnia y la música. Por otro lado, se analiza la moderna institución local que surge a partir del proceso de urbanización y los Consejos de Colaboración. En el capítulo tres se analizan las transformaciones y permanencias en el orden de las relaciones sociales de la institución tradicional y su relación actual con el orden de las relaciones sociales de la institución moderna para la urbanización, los grados de interpenetración y combinación mutua y la importancia de la urbanización en esta relación.

Equilibration of Concentrated Hard Sphere Fluids
We report a systematic molecular dynamics study of the isochoric
equilibration of hard-sphere fluids in their metastable regime close to the
glass transition. The thermalization process starts with the system prepared in
a non-equilibrium state with the desired final volume fraction {\phi} but with
a prescribed non-equilibrium static structure factor S_0(k; {\phi}). The
evolution of the {\alpha}- relaxation time {\tau}{\alpha} (k) and long-time
self-diffusion coefficient DL as a function of the evolution time tw is then
monitored for an array of volume fractions. For a given waiting time the plot
of {\tau}{\alpha} (k; {\phi}, tw) as a function of {\phi} exhibits two regimes
corresponding to samples that have fully equilibrated within this waiting time
({\phi} \leq {\phi}(c) (tw)), and to samples for which equilibration is not yet
complete ({\phi} \geq {\phi}(c) (tw)). The crossover volume fraction {\phi}(c)
(tw) increases with tw but seems to saturate to a value {\phi}(a) \equiv
{\phi}(c) (tw \rightarrow \infty) \approx 0.582. We also find that the waiting
time t^(eq)_w({\phi}) required to equilibrate a system grows faster than the
corresponding equilibrium relaxation time, t^(eq)({\phi}) \approx 0.27 \times
[{\tau}{\alpha} (k; {\phi})]^1.43, and that both characteristic times increase
strongly as {\phi} approaches {\phi}^(a), thus suggesting that the measurement
of equilibrium properties at and above {\phi}(a) is experimentally impossible

Confirmation of symmetrical distributions of clinical attachment loss and tooth loss in a homogeneous Mexican adult male population
Background/purpose
To ascertain whether or not clinical attachment loss and tooth loss are present with similar severity and prevalence across the two sides of the mouth in a homogeneous sample of urban male adults.
Materials and methods
A cross-sectional study was carried out on 161 policemen (a largely homogeneous group in terms of ethnic background, socioeconomic status, sex, occupation, and medical/dental insurance) in Campeche, Mexico. Periodontal examinations were undertaken using the Florida Probe System in a dental chair by one trained and standardized examiner (kappa ≥ 0.60) to determine clinical attachment loss and tooth loss. We examined six sites in all teeth present in the mouth (a maximum of 168 sites, no third molars). Because of correlated data between observations, McNemar (for tooth loss) and Wilcoxon (for attachment loss) signed-rank tests were used to compare right and left sites within the same patient.
Results
The mean age was 38.4 ± 11.0 years. The mean number of teeth present was 24.4 ± 4.6; the mean number of periodontal sites/person was 146.7 ± 27.8. All P values were ≥ 0.05 (except for attachment loss in the upper first premolars), suggesting that there were no statistically significant differences between the right and left sides for the frequency of presentation of these two conditions.
Conclusion
Tooth loss and attachment loss measurements largely resemble each other on both sides of the mouth
Escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae) de Colombia
Los escarabajos coprófagos son un gremio bien definido de la familia Scarabaeidae, subfamilia Scarabaeinae, que comparten características morfológicas, ecológicas y de comportamiento particulares (Halffter 1991). Sus principales distintivos biológicos son la asociación con el excremento y/o carroña de mamíferos y otros vertebrados, su especial modo de reproducción, así como las múltiples estrategias de aprovechamiento del excremento para su alimentación y reproducción (Halffter & Matthews 1966; Halffter & Edmonds 1982
