Attitudes and affect towards statistics - quality of the learning experience of statistics of first year psychology studends
No full textIn this purely exploratory longitudinal research, I try to identify factors influencing attitudes and affect towards statistics in first year psychology students and to model these influences. In a total of three surveys, at the start, during and at the end of the first semester, I measure antecedents of and changes in attitudes towards statistics. The choice of factors measured is based on the body of literature regarding that topic and anecdotal evidence of the researcher.
The aim of this study is to investigate and model multiple known and yet unexplored factors together for the first time and to find hints on causality in the change and interaction of these factors in the chronological progression.
With the results I want to contribute to identifying starting points for interventions to increase attitudes and affect of psychology students towards statistics by improving the quality of their statistics learning experience
Anchoring and Adjustment: A Critical Test of the Time Hypothesis in Anchor Effects
No full textA study conducted to test the time-hypothesis as one core element of the TOTE-model of Anchoring and Adjustment
Overadjustment effects in Anchoring Paradigms
No full textThe Anchor-Effect is a well researched and robust, yet not fully understood psychological phenomenon. Based on the re-analysis of existing studys, we noticed that the use of visual analogue scales in Anchoring Paradigms annulates the insufficient-adjustment-effect, and, in contrast, we even noticed overadjustment-effects.
This study is conducted to yield evidence of whether the Anchor Effect can be reversed by the use of a visual analogue scale or not
Integrating dialectical behaviour therapy into my clinical practice model as a northern social worker
No full textA Master of Social Work practicum at Walmsley and Validity Counselling was completed in support of my desire to advance my general clinical skills and integrate Dialectical Behaviour Therapy (DBT) into my personal practice model. This report begins with a placing of self and localization of practice considerations to northern British Columbia. A literature review on DBT is provided as context for reflection on my learning goals, which explore topics of professional drift, private versus non-profit organization models, northern practice considerations, component versus comprehensive DBT practice, and the cultural safety of mindfulness and acceptance-based therapies. The wisdom and skills gained from this experience, particularly the integration of DBT-informed therapy into my personal practice model, are reviewed in chapters on learning outcomes and implications for practice. This practicum resulted in a strong desire to continue to practice emotion and family focused social work in Prince George, British Columbia
Circulating vaspin is unrelated to insulin sensitivity in a cohort of nondiabetic humans
No full textObjective: To study the association of vaspin with glucose metabolism.
Design: Cross-sectional and intervention study.
Subjects and methods: The association of serum vaspin with metabolic and anthropometric characteristics was investigated in 108 volunteers. Euglycemic–hyperinsulinemic clamps (EHC) were performed in 83 of the participants. Changes of circulating vaspin levels were additionally studied in a crossover study using 300 min EHC with lipid versus saline infusion (n=10).
Results: Neither glucose tolerance status nor insulin sensitivity, both as measured using EHCs and using homeostasis model assessment for insulin resistance (HOMA-IR), was significantly associated with serum vaspin in the cross-sectional study. Furthermore, there was no effect of short-term lipid-induced insulin resistance due to a 300 min intravenous lipid challenge on circulating vaspin. However, circulating vaspin levels were significantly elevated in women using oral contraceptives (OC), both compared to women without OC intake (1.17±0.26 vs 0.52±0.09 ng/ml, P=0.02) and males (1.17±0.26 vs 0.29±0.04 ng/ml, P=0.01). After exclusion of OC using females and stratification according to body mass index (BMI), a significant sexual dimorphism in subjects with a BMI <25 kg/m2 was observed (males 0.21±0.04 ng/ml versus females 0.70±0.16 ng/ml, P=0.009).
Conclusion: Our results support the existence of a sexual dimorphism regarding circulating vaspin. The lack of an association of serum vaspin with HOMA-IR and M value indicates, however, no major role for vaspin concerning insulin sensitivity in nondiabetic humans

Falsifying the Insufficient Adjustment Model: No Evidence for Unidirectional Adjustment From Anchors
No full textAfter considering a more or less random number (i.e., an anchor), people’s subsequent estimates are biased toward that number. Such anchoring phenomena have been explained via an adjustment process that ends too early. We present a formalized version of the insufficient adjustment model, which captures the idea that decreasing the time that people have to adjust from anchors draws their estimates closer to the anchors. In four independent studies (N = 898), we could not confirm this effect of time on anchoring. Moreover, anchoring effects vanished in the two studies that deviated from classical paradigms by using a visual scale or a two-alternative forced-choice paradigm to allow faster responses. Although we propose that the current version of the insufficient adjustment model should be discarded, we believe that adjustment models hold the most potential for the future of anchoring research, and we make suggestions for what these might look like
Effects of Bivariation Viscosity and Magnetic Field on Trapping in a Uniform Tube with Peristalsis
No full textIn recent papers, Mehdi Lachiheb has considered fluid viscosity through a peristaltic tube and a channel as a function of the radial and axial components. This author discussed the trapping phenomenon at the centerline of a peristaltic tube and a channel, the pressure rise, and the drag (friction) forces without a magnetic field. Considering the importance of magnetohydrodynamic fluids in bioengineering and medical sciences, we discussed the effects of bivariation viscosity and magnetic field on the trapping phenomenon at the centerline, separated flow on the wall surface of the peristaltic tube, the drag (friction) forces, and the pressure rise. To solve the problem under low Reynolds and long wavelength assumptions, the velocity field and pressure gradient as functions of Hartmann number, amplitude ratio, viscosity parameter, and volume flow rate were obtained using the perturbation approach in terms of Hartmann number (M \u3c 1). The peristaltic pumping and augmented pumping regions were discussed through drag (friction) forces and the pressure rising. In addition, separation flow points on the surface of the wall were determined numerically
