Criteria for the Selection of Students into a Counseling Program: A Review of Literature

In his paper, Graduate Education in Psychology - A Passionate Statement Carl Rogers (1957) has stated, \u27We are doing an unintelligent, ineffectual and wasteful job of preparing psychologists, to the detriment of our discipline and society. “” He further stated, \u27We should be selecting and training individuals for creative effectiveness in seeking out and discovering the significant new knowledge which is meeded. He then examines ten implicit assumptions on which programs of graduate education appear to be based, showing them to be totally inadequate in training future psychologists. It is time to reevaluate the purpose, procedure, and content of graduate programs in psychology

MAXIMAL-LENGTH SEQUENCE CODE CLASSIFICATION OPTIMIZATION PROCEDURE UTILIZING DEEP LEARNING NEURAL NETWORKS

Direct sequence spread spectrum techniques are often utilized in encoding communications signals because they can decrease signal spectrum lower than the thermal noise floor of a receiver, making them harder to detect. Accurate and timely classification of spreading codes for message decoding has become an area of interest. In this work, we evaluate the difference in classification performance between a traditional matched filter bank method and trained neural networks. We demonstrate that trained neural networks may out perform matched filters specifically in the medium SNR range. Additionally, we explore performance of a neural network trained to detect and classify direct sequence coded signals along with a null alternative by adding a “noise only” signal classification option. We find that there is a probability of false alarm (a) associated with a neural network trained to detect signals with a “noise only” classification option. We conclude that trained neural networks offer an increase in both percentage of classification () and time-to-classify performance. However, we also conclude that more work is required to optimize the neural network for the decoding of preamble codes of different lengths and types. This work demonstrates the feasibility of using trained neural networks for use in decoding direct sequence coded signals.Distribution Statement A.

Diet and Exercise Interventions Following Coronary Artery Bypass Graft Surgery: A Review and Call to Action

Coronary artery bypass graft (CABG) surgery has been used for the treatment of coronary artery disease (CAD) for approximately 50 years, and has been performed on millions of people globally. However, little is known about the impact of diet and exercise on long-term outcomes of patients who have undergone CABG surgery. Although clinical practice guidelines on the management of this patient population have been available for approximately 2 decades, evidence regarding secondary prevention behavioral interventions, lifestyle modifications and self-management to slow the progressive decline of CAD, reduce cardiac hospitalizations, and prevent reoperation remains virtually absent from the literature. Diet and exercise are modifiable factors that affect secondary CAD risk. This article reviews the relevant current literature on long-term diet and exercise outcomes in patients who underwent CABG. The limited available literature shows the positive impacts of exercise on psychosocial well-being and physical fitness. Current evidence indicates diet and exercise interventions are effective in the short-term, but effects fade over time. Potential age and sex differences were found across the reviewed studies; however, further research is needed with more rigorous designs to replicate and confirm findings, and to define optimal management regimens and cost-effective prevention strategies

Advancing the future of physical activity guidelines in Canada: an independent expert panel interpretation of the evidence

The Canadian Society for Exercise Physiology, in partnership with the Public Health Agency of Canada, has initiated a review of their physical activity guidelines to promote healthy active living for Canadian children, youth, adults and older adults; previous guidelines were released in 2002, 2002, 1998 and 1999 respectively. Several background papers from this project were published recently and provide foundation evidence upon which to base new guidelines. Furthermore, comprehensive systematic reviews were completed to ensure a rigorous evaluation of evidence informing the revision of physical activity guidelines for asymptomatic populations. The overall guideline development process is being guided and assessed by the AGREE II instrument. A meeting of experts was convened to present the evidence complied to inform the guideline revisions. An independent expert panel was assembled to review the background materials and systematic reviews; listen to the presentations and discussions at the expert meeting; ask for clarification; and produce the present paper representing their interpretation of the evidence including grading of the evidence and their identification of needs for future research. The paper includes also their recommendations for evidence-informed physical activity guidelines

Frontal cortex differentiates between free and imposed target selection in multiple-target search

Cognitive control can involve proactive (preparatory) and reactive (corrective) mechanisms. Using a gaze-contingent eye tracking paradigm combined with fMRI, we investigated the involvement of these different modes of control and their underlying neural networks, when switching between different targets in multiple-target search. Participants simultaneously searched for two possible targets presented among distractors, and selected one of them. In one condition, only one of the targets was available in each display, so that the choice was imposed, and reactive control would be required. In the other condition, both targets were present, giving observers free choice over target selection, and allowing for proactive control. Switch costs emerged only when targets were imposed and not when target selection was free. We found differential levels of activity in the frontoparietal control network depending on whether target switches were free or imposed. Furthermore, we observed core regions of the default mode network to be active during target repetitions, indicating reduced control on these trials. Free and imposed switches jointly activated parietal and posterior frontal cortices, while free switches additionally activated anterior frontal cortices. These findings highlight unique contributions of proactive and reactive control during visual search

On the elliptic nonabelian Fourier transform for unipotent representations of p-adic groups

In this paper, we consider the relation between two nonabelian Fourier transforms. The first one is defined in terms of the Langlands-Kazhdan-Lusztig parameters for unipotent elliptic representations of a split p-adic group and the second is defined in terms of the pseudocoefficients of these representations and Lusztig's nonabelian Fourier transform for characters of finite groups of Lie type. We exemplify this relation in the case of the p-adic group of type G_2.Comment: 17 pages; v2: several minor corrections, references added; v3: corrections in the table with unipotent discrete series of G
