    Research self-efficacy (RSE) is a key concept not only for counselor educators as successful researchers but also for the advancement of counselor education field. In the literature, researchers have studied multiple factors (e.g., research interest, productivity) to understand the complex nature of RSE phenomenon. Despite being informative, these studies only focused on partial aspects of the multilayered RSE, showing methodological and conceptual limitations. Particularly, we do not have a holistic understanding of RSE and the interrelated relationship among the factors informing RSE. In the current study, the researcher used a mixedmethods design, Concept Mapping (Kane & Trochim, 2007) to explore the factors influencing counselor education doctoral students’ RSE in CACREP-accredited doctoral programs. Current study findings yielded 17 clusters represented in six regions describing the intrapersonal, interpersonal, and systemic levels of Ecological Model (McLeroy et al., 1988). The researcher discussed the findings in the view of the current literature along with implications for researcher training and future research practices as well as with the limitations of current study

    Single cutter models constitute a cornerstone to understand the cutting process while drilling. There are various experimental and numerical studies on simulating cutting behavior of a single cutter in order to optimize drilling performance. In this study, the numerical model developed to analyze single PDC cutter performance was verified with the experimental data. Numerous runs with different model properties and rock post failure properties were conducted for the purpose of creating a model that works accurately in different conditions. The data used in this study for model verification was obtained from an experimental study reported in the literature. The study focuses on a single cutter-rock model to understand how axial and rotational loads change under different cutting conditions. The model is composed of a single cutter interacting with the rock specimen and was developed using FLAC 3D, an explicit finite difference program. Back analysis was performed with the reported laboratory experiments and various formation parameters in the model were varied to match the experimental results

    The products of miniaturization, such as mobile phones, personal digital assistants, computers and other electronic devices have become an indispensable part of our daily lives. Nowadays, more and more industrial products including some medical and electromechanical products contain micro scale metal parts such as connector pins, resistor caps, screws, contact springs and chip lead frames. Miniaturization brings the challenge of realizing the production of these microscale metals parts. Microforming, due to its well known advantages of high production rates, excellent material utilization, and low costs, is a promising manufacturing method compared to the alternative processes in this field. However, well-established conventional, macroscale metal forming processes can not simply be miniaturized without considering possible size effects. The goal of this research was to determine if deformation size effects occur with miniaturization. Both deformation size effects with respect to specimen size and grain size were considered through the investigation of two processes, microextrusion and microbending. In both of these forming processes, deformation gradients are generated through the cross-sections of the specimens. To analyze these deformation size effects, the distribution of the deformation was characterized by micohardness evaluations. In addition for microextrusion, X-Ray pole figure analyses and microstructure analyses were also performed. For both processes, the deformation distribution through the cross sections of the fine grained specimens is not affected significantly by the specimen size (i.e. deformation distribution is independent from the specimen size) since the hardness profiles for the all specimen sizes are similar. However, as the specimen size is miniaturized, the deformation distribution of the coarse grained specimens deviates from the fine grained ones, and from the larger size specimens. In addition, as the specimen size decreases the coarse grained specimens have higher hardness increase values at the central region compared to fine grained specimens. This occurs due to the penetration of deformation from highly strained outer regions to the less strained inner regions (or expansion of the highly deformed regions)

    Abstract: Research self-efficacy (RSE) has been mainly considered as an intrapersonal aspect of researcher identity development. Utilizing a systemic lens, we examined factors informing counselor education doctoral students’ RSE in CACREP-accredited doctoral programs. Concept mapping, a mixed-method design, yielded 17 clusters representing six regions describing the factors informing counselor education doctoral students’ RSE. We discussed the results with training and research implications, and limitations. What is the public significance of this article? The present study suggests that there are environmental and relational factors affecting doctoral student’s research self-efficacy (RSE) as well as the previously considered individual factors. Acknowledgement and intentional incorporation of all of these factors may be critical in the counselor education research training process

    While many US residents like listening to African stories, hearing African stories is difficult because designing effective curricula and teaching about African contexts appear to be a major challenge in US social studies education.  Drawing on postcolonial theory, we analyzed the discourses of two contemporaneous historical documents to demonstrate the complexities in meaning making processes inherent in the indigenous Yorubas’ social practices, in the southwestern part of Nigeria.  Differential complex perspectives on Yoruba social practices are evident in both colonialist and native authored historical documents from the same time period when colonialist authority had been established but indigenous cultural practices were evident and continuing.  The Colonialist authored historical document indicate misunderstanding of the meaning of some Yoruba social practices.  The native authored historical document provides underlying meanings for social practices and ties portrayal of social practices to indigenous ways of being.  The discussion calls attention to how colonial legacies influence meaning making, meaning made from, and knowledge made available by, historical documents, as well as ways forward in addressing contemporary discourse on Africa in US social studies curriculum
