Potenciais aves dispersoras de sementes das espécies vegetais zoocóricas da Mata da Bica, Botucatu - SP

The semidecidual forests, as tropical forests, presents zoochoric dispersal syndrome in the most of their plant species, with approximately one third of frugivorous species responsible for the seeds dispersal are birds. The bills width is a limiting factor, it must be equal or bigger than the seeds width, because the viable seeds dispersal depends on leaving the digestive system after been swallowed hole. Birds and plants inventorys were realized in a semidecidual Forest fragment, in Botucatu – SP, called Mata da Bica. After this, the birds consumers of fuits/seeds were selected (frugivorous, granivorous and onivorous) and also the zoochoric plants, both for building a possibilities matrix, to verify the potential seed dispersers according to the seeds and bills width. Going to the matrix end we can observe a decrease in the interaction possibillities, because the seeds width increases and the bills width decreases. It has been observed that 50,7% seeds could be dispersed by all listed birds, because the seeds were narrower than the narrowest bill. In the other way large seeded species, as Holocalix balansae and Hymemaea courbaril has shown only two possible dispersers: Trogon surrucura and Piaya cayana. There are no possible dispersers to Syagrus oleraceae in the matrix. The need for large birds or other animals that works as large seed disperses demand conservation efforts, since most of these animals need big and conserved areas for their life habits

Pulperos rurales: entre la vida privada y la pública

Este trabajo estudia la vida privada del pulpero rural de la campaña de Buenos Aires y las actividades que desarrolla cuando no se encuentra frente a su negocio. A través del análisis de testamentos e inventarios de pulperos rurales de Buenos Aires de fines del siglo XVIII y principios del XIX el estudio intenta penetrar en la intimidad y en las actividades alternativas que desempeñaban. El trabajo logra comprobar la existencia de un espacio protegido de la intromisión pública. Si bien la frontera que separaba ambos territorios muchas veces aparecía desfigurada, el espacio privado ha sido conquistado en mayor o menor medida por el pulpero rural. Con ello este artículo cuestiona la visión de rusticidad general que envolvía a la vida en la campaña y ubica a los pulperos dentro de los sectores medios que poblaban la campaña.

Psychometric properties of the School Anxiety Inventory-Short Version in Spanish secondary education students

Background: The School Anxiety Inventory (SAI) can be applied in different fields of psychology. However, due to the inventory’s administration time, it may not be useful in certain situations. To address this concern, the present study developed a short version of the SAI (the SAI-SV). Method: This study examined the reliability and validity evidence drawn from the scores of the School Anxiety Inventory-Short Version (SAI-SV) using a sample of 2,367 (47.91% boys) Spanish secondary school students, ranging from 12 to 18 years of age. To analyze the dimensional structure of the SAI-SV, exploratory and confirmatory factor analyses were applied. Internal consistency and test-retest reliability were calculated for SAISV scores. Results: A correlated three-factor structure related to school situations (Anxiety about Aggression, Anxiety about Social Evaluation, and Anxiety about Academic Failure) and a three-factor structure related to the response systems of anxiety (Physiological Anxiety, Cognitive Anxiety, and Behavioral Anxiety) were identified and supported. The internal consistency and test-retest reliability were determined to be appropriate. Conclusions: The reliability and validity evidence based on the internal structure of SAI-SV scores was satisfactory.

Lageroptimering med hjälp av multikriterieanalys : En fallstudie hos KUBALs centrallager

This thesis deals with control of stock in an inventory, focusing on inventory placement. The purpose of this thesis is to reduce the transport distance within the main stock house while gathering inventory. This will be achieved by reconstructing the inventory placement in consideration with how frequently the inventories get picked and mass of the inventory. In particular, the literature and the data that is collected from the company´s business system have laid the foundation for the thesis. In general, interviews and observations also contributed to the data collection. To fulfill the aim and to produce arbitrary results, two issues have been developed regarding which attributes that should determine the position of the inventory in the stock house and how to obtain a more effective inventory structure? The authors have jointly produced a result of suggestions for future inventory placement in terms of picking frequency and weight. Initially a situation analysis was conducted to identify known problems with the inventory´s placement and storage systems. The problems that were identified were that the inventory placement has no consideration regarding picking frequency. To determine the most frequent picked inventory an ABC analysis was conducted. All of the inventories were spread out throughout the whole stock house. To take in account, the additional criterion, which was weight, a multi-criteria analysis was performed in combination with the ABC analysis. The results of the combined analysis provided that the basis for drawing up concepts for future inventory placement. The proposal includes optimized inventory placements in different zones of the most frequently picked inventory with weight as an additional criterion.
