Relationship between depressive symptoms, performance and mastery goals, rumination and affect

Baines, George William January 2014 (has links)
The social cognitive theory of Depression proposed by Rothbaum et al. (2008) integrates theory originating from the motivation, cognitive and rumination literature. Following stressors, those with vulnerable self-beliefs are predicted to adopt performance goals that aim to avoid threats to self-worth, necessitating protective mechanisms like rumination. Both the goals themselves and rumination serve to protect self-worth but are proposed to have depressogenic consequences. This theory, combined with literature on contingent self-worth and trait rumination in depression, led to an elaborated social cognitive model whereby rumination mediates the relationship between goal orientation and depression. The current study aimed to test this model. Seventy two healthy participants participated in an experimental manipulation of goal orientation prior to a difficult anagram task and rated their sadness, anxiety, and state rumination following a stressor and during a subsequent sustained attention task. The results suggested many of the hypotheses about condition differences were not supported and this may have been due to an unsuccessful task goal manipulation. However extrinsic contingent self-worth based on other’s approval was found to moderate the effect of goal orientation on task based depressive affect and rumination. For those reporting high contingent self-worth based on other’s approval, cuing a performance goal was related to significantly higher sadness and rumination following a stressor than cuing mastery goal. Findings suggest that therapy specifically focusing on assessing extrinsic contingent self-worth and associated vulnerable self-beliefs, and encouraging the adoption of mastery goals may be therapeutically beneficial in making people less reactive to stressful life events.

Multi-Model Bayesian Analysis of Data Worth and Optimization of Sampling Scheme Design

Xue, Liang January 2011 (has links)
Groundwater is a major source of water supply, and aquifers form major storage reservoirs as well as water conveyance systems, worldwide. The viability of groundwater as a source of water to the world's population is threatened by overexploitation and contamination. The rational management of water resource systems requires an understanding of their response to existing and planned schemes of exploitation, pollution prevention and/or remediation. Such understanding requires the collection of data to help characterize the system and monitor its response to existing and future stresses. It also requires incorporating such data in models of system makeup, water flow and contaminant transport. As the collection of subsurface characterization and monitoring data is costly, it is imperative that the design of corresponding data collection schemes is cost-effective. A major benefit of new data is its potential to help improve one's understanding of the system, in large part through a reduction in model predictive uncertainty and corresponding risk of failure. Traditionally, value-of-information or data-worth analyses have relied on a single conceptual-mathematical model of site hydrology with prescribed parameters. Yet there is a growing recognition that ignoring model and parameter uncertainties render model predictions prone to statistical bias and underestimation of uncertainty. This has led to a recent emphasis on conducting hydrologic analyses and rendering corresponding predictions by means of multiple models. We develop a theoretical framework of data worth analysis considering model uncertainty, parameter uncertainty and potential sample value uncertainty. The framework entails Bayesian Model Averaging (BMA) with emphasis on its Maximum Likelihood version (MLBMA). An efficient stochastic optimization method, called Differential Evolution Method (DEM), is explored to aid in the design of optimal sampling schemes aiming at maximizing data worth. A synthetic case entailing generated log hydraulic conductivity random fields is used to illustrate the procedure. The proposed data worth analysis framework is applied to field pneumatic permeability data collected from unsaturated fractured tuff at the Apache Leap Research Site (ALRS) near Superior, Arizona.

A Woman’s Worth: A Phenomenological Study on Black Women Entrepreneurship And Building Net-Worth

Young, Miriam 03 May 2017 (has links)
The purpose of this study is to explore Black women’s experience of becoming and being entrepreneurs and accumulating wealth. Through interview questions that examine social capital, this study allows eight Black women to recall their ever-changing and evolving experience of entrepreneurship and economic mobility. This qualitative study goes beyond empirical data of the wealth gap and the numerical trends of Black women entrepreneurs. The study allowed for Black women to share their experience with wealth accumulation and the social factors, such as networks and relationships that attributed to starting and sustaining a business. Findings and implications will be discussed.

The Angoff Method and Rater Analysis: Enhancing Cutoff Score Reliability and Accuracy

Baker, Charles E., 1957- 12 1900 (has links)
At times called a philosophy and other times called a process, cutting score methodology is an issue routinely encountered by Industrial/Organizational (I/0) psychologists. Published literature on cutting score methodology appears much more frequently in academic settings than it does in personnel settings where the potential for lawsuits typically occurs more often. With the passage of the 1991 Civil Rights Act, it is no longer legal to use within-group scoring. It has now become necessary for personnel psychologists to develop more acceptable selection methods that fall within established guidelines. Designating cutoff scores with the Angoff method appears to suit many requirements of personnel departments. Several procedures have evolved that suggest enhancing the accuracy and reliability of the Angoff method is possible. The current experiment investigated several such procedures, and found that rater accuracy methods significantly enhance cutoff score reliability and accuracy.

Corkodiles : Challenging body standards by exploring techniques of cutting and assembling primitive materials, which are mainly derivatives of wood, in order to rethink the visual expression of the body.

Im, Vika January 2016 (has links)
The motive of this work is to illustrate and visualize the socio-political objectification of the female body, in order to suggest explanations as to how female body standards are derived as a result of this objectification. The objective was obtained by exploring cut and assembling designs with powerful visual expressions, with sustainability as a point of emphasis. As the result 8 shapes were created out of one single pattern formula, the formula that would probably never be discovered if the starting point were not a fragile cork material.
