Face recognition under pose variations

In recent years, face recognition has attracted significant attention from the research and commercial communities. Because of the wide variation in face images, face recognition for real applications remains a very challenging problem. A large number of face recognition algorithms, along with their modifications, have been proposed over the past three decades. This paper presents a review of the typical algorithms that aim to overcome one of the main obstacles in the face recognition task, the variations in face pose. These algorithms are categorized and briefly described. Future research challenges in pose-invariant face recognition are also identified.     

The influence of study methods and knowledge processing on academic success and long‐term recall of anatomy learning by first‐year veterinary students

The purpose of this investigation was to quantitatively and qualitatively identify the study methods and learning strategies that veterinary students used to study anatomy during their first year of professional school and to correlate these with their academic achievement and long‐term recall of information. It was surmised that active study methods would be more beneficial than passive method, but this hypothesis was not supported. The activity or passivity of each study method was secondary to the way in which the students processed the learning. No single study method was associated with academic success or long‐term recall; instead, successful students used a multitude of study methods while the struggling students relied on a single method alone, although these methods varied from student to student. Students and their study methods were profiled using the qualitative technique known as phenomenographic analysis to find those who studied in a deep or surface way. The deep‐processing students, who commonly used multiple study methods, not only succeeded in the class but also had better recall. Students who relied on a memorization‐heavy surface approach to learning had limited recall and tended to perform poorly in the class. These results strongly suggest that by encouraging students to integrate their studying by using multiple methods educators can improve both student grades and recall of complex topics.

Learning from Writing in College Biology

This study used both quantitative and qualitative analyses to examine the influence of written arguments on learning in a college level introductory biology class and the types of metacognition employed by students while writing. Comparison of a treatment and control group indicates that the writing assignments used had minimal impact on overall content learning as measured by conventional exams. Subsequent interviews and think-aloud protocols with a subset of students indicated that writing arguments had the potential to foster learning through forward and backward search strategies. However, few of the students took advantage of this opportunity to use metacognitive skills. This study suggests that preparing written arguments is not sufficient, by itself, to have a reliable effect on student learning and is consistent with the view that students must be explicitly taught when and how to use different metacognitive strategies.     

A National Survey of School Counselor Preparation Programs: Screening Methods,Faculty Experiences,Curricular Content,and Fieldwork Requirements

This article describes the results of a national survey regarding the preparation of entry‐level school counseling students. The questionnaire asked counselor educators about credit hours, screening methods, previous faculty experiences in a school setting, course content, and fieldwork requirements. Survey results revealed similarities and differences among school counselor preparation programs.     

Assessing the impact of information services in a regionalized health-care organization

Objectives: Assessment of the usage of medical library services before and after the implementation of several new services, as well as assessment of the clinical impact of the information provided by the medical library. Methods: A sample of employees, residents and physicians were surveyed using a stratified, random selection process in two surveys 4 years apart. The response rate for the first survey was 52% and the response rate for the second survey was 35.2%. Results: Differences in usage included increased overall use of the librarians and library services, decreased use of the Internet as a source of information, and direct and indirect impacts upon patient care. Information needs of respondents also increased to where 65% of employees and 94% of physicians require information at least once a week. Patient management was the main reason for needing information. The top two specific uses were to find out about a condition and determine a treatment plan. Conclusions: These findings parallel some of the findings of other researchers, and contradict the findings of others. Possible explanations for these findings and implications for future research are discussed.     

Sound’s use in instructional software to enhance learning: a theory-to-practice content analysis

Sound may hold great promise for instructional software by supporting learning in a variety of ways. Conceptual and preconceptual barriers, however, still appear to prevent software designers from using sound more effectively in their instructional products. Interface books seldom discuss the use of sound and when they do, it is most often simple verbatim narration of on-screen text. This content analysis of 12 award-winning instructional software products indicated that, while sound is being incorporated into many learning environments, many instructional designers are using sound only for literal, information conveyance and not yet exploring how to exploit the associative potential of music, sound effects, and narration to help learners process the material under study more deeply.
