Estilo motivacional, tipos de motivación, emociones y rendimiento en las matemáticas

Desde la Teoría de la Autodeterminación, el estudio tuvo como objetivo analizar la relación entre el estilo motivacional del docente percibido por el estudiante (apoyo a la autonomía y control), los tipos de motivación (autónoma y controlada), las emociones académicas (disfrute y ansiedad) y el rendimiento académico en matemáticas, en 269 estudiantes de 5to y 9no grado de dos escuelas privadas de Lima. También estudió las diferencias en el estilo motivacional, los tipos de motivación y las emociones académicas en ambos grados de estudio. Adicionalmente, se analizaron las propiedades psicométricas de los instrumentos y se halló evidencia adecuada de validez y confiabilidad. Se encontró que todas las variables del lado claro de la motivación (apoyo a la autonomía, motivación autónoma y disfrute) estaban correlacionadas y se relacionaban positivamente con el rendimiento académico. Asimismo, las del lado oscuro (estilo de control, motivación controlada y ansiedad) se relacionaban entre ellas y se asociaban negativamente con el rendimiento. El análisis de senderos indicó que el estilo motivacional percibido predice el tipo de motivación, este predice las emociones académicas y finalmente estas son predictoras del rendimiento académico, tanto en el lado claro como el oscuro. Adicionalmente, hay una relación entre el estilo motivacional y las emociones académicas, mediada por el tipo de motivación.Based on the Self-determination Theory, this study examines the relationship between the motivating teaching style (autonomy support and control), types of motivation (autonomous and controlled), academic emotions (enjoyment and anxiety) and academic performance in mathematics, in 269 students from 5th and 9th grade from two private schools of Lima. We also studied differences in motivating style, types of motivation and academic emotions in both grades. Additionally, we analyzed the psychometric properties of the instruments and they were valid and reliable. All the variables on the bright side of motivation (perceived autonomy support, autonomous motivation and enjoyment) correlated with each other and were positively related to academic performance. Likewise, those on the dark side (perceived controlling style, controlled motivation and anxiety) were related to each other and were negatively associated with performance. The path analysis indicated that the perceived motivating style predicts the type of motivation, this predicts the academic emotions and finally these are predictors of academic performance, both on the bright and the dark side. Additionally, a relationship between motivating style and academic emotions, mediated by the type of motivation, was found.Tesi

Symbolic Politics or Generification ? The Ambivalent Implications of Tree Ordinations in the Thai Environmental Movement

Since the early 1990s, tree ordinations have become an important practice for some Thai environmental activists who seek greater legitimacy for local management and use of natural resources.  This paper, explores the political and cultural effects of tree ordinations by applying the concepts of “cultural objectification” and “cultural generification. It argues that recent uses of tree ordinations depend on a process of cultural objectification, facilitating the generification of the ritual and its various components as an example of the larger category of “local wisdom.” Significant forms of power difference are implicated in the process. Middle class NGO activists largely controlled the practice and representation of the ritual and its symbols, and tended to objectify and simplify the values and practices of rural people. The tree ordinations of 1996-1997, dedicated to King Rama IX, had the further effect of symbolically bolstering the hierarchical structure of the Thai state and Thai society as a whole – a structure in which local leaders and middle class NGO activists exercise power as arbiters of “good” and “bad” culture among rural people. These are the ambiguous implications to which the title of this article refers: a process of objectification and generification and its place in the reproduction of a hierarchical political and cultural order, together with some decidedly positive outcomes of tree ordinations for the conservation and control of natural resources by rural people. Key words: Thailand, environmental activism, social hierarchy, power, cultural objectification

Interactions between urban water policy, residential irrigation, and plant & bird diversity in the Fresno-Clovis Metro Area

*Background/Question/Methods:*

Ecological theory has begun to incorporate humans as part of coupled socio-ecological systems. Modern urban development provides an excellent laboratory to examine the interplay among socio-ecological relationships. Urban land and water management decisions result from dynamic interactions between institutional, individual and ecological factors. Landscaping and irrigation at any particular residence, for example, is a product of geography, hydrology, soil, and other local environmental conditions, the homeowners’ cultural preferences, socioeconomic status, identity construction, neighborhood dynamics, as well as zoning laws, market conditions, city policies, and county/state/federal government regulations. Since land and water management are key determinants of habitat for other species, urban biodiversity is strongly driven by the outcome of interactions between these variables. This study addresses the significance of water as a key variable in the Fresno-Clovis Metropolitan Area (FCMA), shaping current patterns of landscape and water use, at a time when the city of Fresno is installing meters as a regulatory tool to conserve water. We combine data from a citizen science bird monitoring project, field surveys of trees, and mail surveys of residents to address interactions among key components of the urban socioecological system.

*Results/Conclusions:*

We present results of multivariate analyses of bird and tree surveys to show that neighborhood income and irrigation levels interact to influence species diversity of both taxa. Data from the Fresno Bird Count found that bird species richness and functional group diversity are both strongly correlated with residential irrigation and neighborhood income levels. Tree species diversity shows a similar pattern. We examine these results to test and develop several theoretical models explaining outdoor water use behaviors, with the aim of assessing the resilience of such behaviors with the introduction of water metering in Fresno, and the resilience of urban plant and bird communities to resulting changes in water use in the landscape. We argue that socioeconomic status results from a complex interplay of cultural, economic, structural, and social-psychological factors, influencing institutional policies regarding the governance of water resources, and in turn impacts biodiversity within the urban landscape through spatial and temporal variations in water usage. This study is part of a long-term research project that examines the impacts of human water usage and water use policies on biodiversity within an urban environment

College Students, Technology, and Time

Our research explores CUNY students’ lived experiences using digital technology in and out of class, on and off campus. Beyond checking grades or emailing a professor, students use digital technology to create space and time for their schoolwork. However, technology can also impede students’ opportunities for making space and time. Understanding how students use digital technology is crucial for colleges and universities to better support students in their academic work

Ethnographic methods in academic libraries: A review

Research in academic libraries has recently seen an increase in the use of ethnographic-based methods to collect data. Primarily used to learn about library users and their interaction with spaces and resources, the methods are proving particularly useful to academic libraries. The data ethnographic methods retrieve is rich, context specific, and often difficult to collect via other methods. This review provides an overview of research demonstrating how ethnography can be applied to learn about a variety of issues in academic libraries, ranging from space use to a way of teaching new students about library resources and facilities

Surgical Experiences of Functioning Neuroendocrine Neoplasm of the Pancreas

We present our surgical experiences with functioning neuroendocrine neoplasms of the pancreas to define its natural history, and to suggest its proper management. From June 1990 to June 2005, patients with diagnosis of functioning neuroendocrine (islet cell) neoplasms of the pancreas were retrospectively reviewed. Fourteen patients (5 men and 9 women) with a median age of 49 years (range, 12 - 68 years) were identified. Twelve patients (86%) had insulinoma, two (14%) had gastrinoma. One (7%) with pancreatic insulinoma was multiple endocrine neoplasia type 1. Intraoperative ultrasound scan (sensitivity, 83%) was the most powerful modality for tumor localization. Fifteen neoplasms with median tumor size 1 cm (range 0-3 cm) were resected. Four insulinomas (26.7%) were located in the head of the pancreas and 5 (36%), in the tail. Another 5 (36%) insulinomas and 1 (7%) gastrinoma were located around the neck area near the SMV or PV. Eleven patients (79%) underwent enucleation, and 2 patients (14%), distal pancreatectomy with splenectomy. 100% of patients with functioning neuroendocrine neoplasms of the pancreas have survived. The overall disease free 10-year survival was found to be about 81%. Exact localization of tumor by intraoperative ultrasound and surgical removal are promising for good prognosis

Low expression of aldehyde deyhdrogenase 1A1 (ALDH1A1) is a prognostic marker for poor survival in pancreatic cancer

<p>Abstract</p> <p>Background</p> <p>Aldehyde deyhdrogenase 1 (ALDH1) has been characterised as a cancer stem cell marker in different types of tumours. Additionally, it plays a pivotal role in gene regulation and endows tumour cells with augmented chemoresistance. Recently, ALDH1A1 has been described as a prognostic marker in a pancreatic cancer tissue microarray. The aim of this study was to reevaluate the expression of ALDH1A1 as a prognostic marker on whole-mount tissue sections.</p> <p>Methods</p> <p>Real-time-quantitative-PCR (qRT-PCR) and Western blotting were used to evaluate the expression profile of ALDH1A1 in seven pancreatic cancer cell lines and one non-malignant pancreatic cell line. Immunostaining against ALDH1A1 and Ki-67 was performed on paraffin-embedded samples from 97 patients with pancreatic cancer. The immunohistochemical results were correlated to histopathological and clinical data.</p> <p>Results</p> <p>qRT-PCR and Western blotting revealed a different expression pattern of ALDH1A1 in different malignant and non-malignant pancreatic cell lines. Immunohistochemical analysis demonstrated that ALDH1A1 was confined to the cellular cytoplasm and occurred in 72 cases (74%), whereas it was negative in 25 cases (26%). High expression of ALDH1A1 was significantly correlated to an increased proliferation rate (Spearman correlation, p = 0.01). Univariate and multivariate analyses showed that decreased expression of ALDH1A1 is an independent adverse prognostic factor for overall survival.</p> <p>Conclusions</p> <p>Immunonhistochemical analysis on whole-mount tissue slides revealed that ALDH1A1 is more abundantly expressed in pancreatic cancer than initially reported by a tissue microarray analysis. Moreover, high expression of ALDH1A1 correlated significantly with the proliferation of tumour cells. Intriguingly, this study is the first which identifies low expression of ALDH1A1 as an independent adverse prognostic marker for overall survival in pancreatic cancer.</p
