Eye Color and its Possible Relation to Behavior

A variable that is capable of indicating one\u27s cognitive and motor capacities has been the dream of many researchers. Until recently however, no researcher has seriously considered an independent variable that is obvious among all people regardless of race or culture. This variable is eye color. This paper is a review of the experimental literature in this field and covers many areas including sociability, perception, learning, athletic abilities, and a few medical anomalies. Several alternative hypotheses are also offered as reasons for the obtained correlations. These ideas include culture, learning, and environment. Two other hypotheses are also presented to explain why eye color does play an important role in determining one\u27s response to environmental stimuli. These ideas include a genetic and physiological basis. It is the hope of this author that this review may stimulate other researchers to perform more experiments in the area to help determine the amount of influence that they eye color has in individual responses to the environment

Hurricane Madness: Teaching, Learning And The Importance Of Flexibility In The Wake Of Disaster

The present study examines stress among college students (N=107) that were exposed to natural disasters at the start of the 2004 Fall Semester after Hurricane Charley and Frances battered Central Florida within three weeks of each other. The study also examines adjustments made by two faculty members during the semester in attempts to reduce student stress while maintaining high academic standards in the wake of disaster. Findings indicate that students experienced a substantial amount of stress as a result of the storms.  Of the students surveyed 50 percent indicated they suffered lost wages or income, 65 percent sustained some damage to their residences, and 63 percent experienced moderate to extremely high levels of stress. Concerning the adjustments implemented by the instructors, 84 percent of the students agreed or strongly agreed that the academic quality of their education was not compromised. While educators must have well-designed and planned courses, when disaster strikes, it is imperative that they incorporate creative and flexible teaching methods and policies in their classrooms

Notes from the Field: 10 Short Lessons on One-Shot Instruction

Librarians teach. It might not be what they planned to do when they entered the profession, or it may have been a secret hope all along. Either way, librarians teach, and one teaching scenario remains quintessential: the one-shot library instruction session. In recognition of the centrality of the one-shot, this article shares several authors\u27 notes from the field. The notes provide a range of strategies for developing pedagogically sound one-shot library instruction sessions, grouped loosely into three categories: planning, delivery, and integration. The authors offer these insights in their own words in hopes that other teaching librarians may benefit from their experiences

Adding 6 months of androgen deprivation therapy to postoperative radiotherapy for prostate cancer: a comparison of short-course versus no androgen deprivation therapy in the RADICALS-HD randomised controlled trial

Background Previous evidence indicates that adjuvant, short-course androgen deprivation therapy (ADT) improves metastasis-free survival when given with primary radiotherapy for intermediate-risk and high-risk localised prostate cancer. However, the value of ADT with postoperative radiotherapy after radical prostatectomy is unclear. Methods RADICALS-HD was an international randomised controlled trial to test the efficacy of ADT used in combination with postoperative radiotherapy for prostate cancer. Key eligibility criteria were indication for radiotherapy after radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to radiotherapy alone (no ADT) or radiotherapy with 6 months of ADT (short-course ADT), using monthly subcutaneous gonadotropin-releasing hormone analogue injections, daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as distant metastasis arising from prostate cancer or death from any cause. Standard survival analysis methods were used, accounting for randomisation stratification factors. The trial had 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 80% to 86% (hazard ratio [HR] 0·67). Analyses followed the intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov, NCT00541047. Findings Between Nov 22, 2007, and June 29, 2015, 1480 patients (median age 66 years [IQR 61–69]) were randomly assigned to receive no ADT (n=737) or short-course ADT (n=743) in addition to postoperative radiotherapy at 121 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 9·0 years (IQR 7·1–10·1), metastasis-free survival events were reported for 268 participants (142 in the no ADT group and 126 in the short-course ADT group; HR 0·886 [95% CI 0·688–1·140], p=0·35). 10-year metastasis-free survival was 79·2% (95% CI 75·4–82·5) in the no ADT group and 80·4% (76·6–83·6) in the short-course ADT group. Toxicity of grade 3 or higher was reported for 121 (17%) of 737 participants in the no ADT group and 100 (14%) of 743 in the short-course ADT group (p=0·15), with no treatment-related deaths. Interpretation Metastatic disease is uncommon following postoperative bed radiotherapy after radical prostatectomy. Adding 6 months of ADT to this radiotherapy did not improve metastasis-free survival compared with no ADT. These findings do not support the use of short-course ADT with postoperative radiotherapy in this patient population

Duration of androgen deprivation therapy with postoperative radiotherapy for prostate cancer: a comparison of long-course versus short-course androgen deprivation therapy in the RADICALS-HD randomised trial

Background Previous evidence supports androgen deprivation therapy (ADT) with primary radiotherapy as initial treatment for intermediate-risk and high-risk localised prostate cancer. However, the use and optimal duration of ADT with postoperative radiotherapy after radical prostatectomy remains uncertain. Methods RADICALS-HD was a randomised controlled trial of ADT duration within the RADICALS protocol. Here, we report on the comparison of short-course versus long-course ADT. Key eligibility criteria were indication for radiotherapy after previous radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to add 6 months of ADT (short-course ADT) or 24 months of ADT (long-course ADT) to radiotherapy, using subcutaneous gonadotrophin-releasing hormone analogue (monthly in the short-course ADT group and 3-monthly in the long-course ADT group), daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as metastasis arising from prostate cancer or death from any cause. The comparison had more than 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 75% to 81% (hazard ratio [HR] 0·72). Standard time-to-event analyses were used. Analyses followed intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov , NCT00541047 . Findings Between Jan 30, 2008, and July 7, 2015, 1523 patients (median age 65 years, IQR 60–69) were randomly assigned to receive short-course ADT (n=761) or long-course ADT (n=762) in addition to postoperative radiotherapy at 138 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 8·9 years (7·0–10·0), 313 metastasis-free survival events were reported overall (174 in the short-course ADT group and 139 in the long-course ADT group; HR 0·773 [95% CI 0·612–0·975]; p=0·029). 10-year metastasis-free survival was 71·9% (95% CI 67·6–75·7) in the short-course ADT group and 78·1% (74·2–81·5) in the long-course ADT group. Toxicity of grade 3 or higher was reported for 105 (14%) of 753 participants in the short-course ADT group and 142 (19%) of 757 participants in the long-course ADT group (p=0·025), with no treatment-related deaths. Interpretation Compared with adding 6 months of ADT, adding 24 months of ADT improved metastasis-free survival in people receiving postoperative radiotherapy. For individuals who can accept the additional duration of adverse effects, long-course ADT should be offered with postoperative radiotherapy.

Contextual Reasoning In Human Cognition And The Implications For Artificial Intelligence Systems

It has been widely known that reasoning with and about context is an essential aspect of human cognition, permeating language, memory, and reasoning capabilities. This integral process is developed over a lifetime through experiential learning. Given that one goal of artificial intelligence has been to create human-like intelligence in a machine, it is essential to include such contextual considerations in system design and implementation. This paper extends the discussion about contextual reasoning in humans and how modeling it in a computer program can help to get closer to the ultimate intelligent machine

Analyzing The Existing Undergraduate Engineering Leadership Skills

Purpose: Studying and analyzing the undergraduate engineering students\u27 leadership skills to discover their potential leadership strengths and weaknesses. This study will unveil potential ways to enhance the ways we teach engineering leadership. The research has great insights that might assist engineering programs to improve curricula for the purpose of better engineering preparation to meet industry\u27s demands. Methodology & Findings: 441 undergraduate engineering students have been surveyed in two undergraduate engineering programs to discover their leadership skills. The results in both programs were revealing that undergraduate engineering students are lacking behind in the visionary leadership skills compared to directing, including and cultivating leadership styles. Recommendation: A practical framework has been proposed to enhance the lacking leadership skills by utilizing the Matrix of Change (MOC), and the Balanced Scorecard BSC) to capture the best leadership scenarios to design virtual simulation environment as per the lacking leadership skills which is the visionary leadership skills in this case. After that, the virtual simulation will be used to provide an experiential learning by replacing human beings with avatars that can be managed or dramatized by real people to enable the creation of live, practical, measurable, and customizable leadership development programs

Looking For A Synergy Between Human And Artificial Cognition

Contextually based reasoning is an essential aspect of human cognition, permeating language, memory, and reasoning capabilities. This integral process is developed over the lifetime through experiential learning. Given the goal of artificial intelligence to mimic human intelligence, it is essential to include such contextual considerations in system design and implementation. We compare selected computational architectures and cognitive paradigms on the basis of key elements in human intelligence understanding in order to illustrate the similarities and differences between the two viewpoints and highlight the potential effectiveness of context based computing. In the literature, we discover meaningful parallels between the assessment of context in cognition and computation which have implications for both fields of study. © 2013 Springer-Verlag
