Despite active research and significant progress in the last three decades on control of human eye movements, it remains challenging issue due to its applications in prosthetic eyes and robotics. Till now, no considerable investigation of this subject is presented in the interdisciplinary sciences. The goal of this paper is to present a distinguished survey of existing literature on the intelligent control of the human eye movements system applied in a huggable pet-type robot as a biomechatronic system.In this study, the basic knowledge of human eye movements control is explained to show how the neural networks in the brainstem control the human eye movements. The geometry and model of human eye movements system are investigated and this system is considered as a nonlinear control system. The specified model may only be an academic exercise. It can have scientific importance in understanding of the human movement system in general. Also, it can be useful for robotics.Intelligent methods such as artificial neural networks and fuzzy neural networks are proposed to control the human eye movements and numerical simulations are presented. It is discussed that the intelligent controls applied to control of human eye movements system are emulated from the neural controls in biological system. 相似文献

Although Richard Rorty's controversial thought has been the subject of many works, there has not been much discussion about his approach to cultural difference. The purpose of this article is to examine how Rorty sees cultural differences philosophically and how he deals with them politically. For him, rationality, morality and even the scope of moral responsibility towards others are defined in terms of solidarity with a particular community and ‘ethnocentrism’, rather than in terms of a universal and metaphysically derived set of criteria. It can be argued that since language, language games and values are mainly components of culture, the latter is one of the most significant communities with which Rorty is concerned, though he is not explicit about it. Nevertheless, Rorty does not think that the moral and philosophical significance of communities, particularly cultural communities, should be reflected in politics. The main argument of the article is that there is an unresolved tension in Rorty's thought between philosophical, moral and emotional attribution of significance to communities and arguably cultural communities, and a disregard for them in the political sphere. This paves the way for outlining an approach to cultural difference that is more just and even more in harmony with Rorty's own philosophy. 相似文献

Faculty use of technology is a critical issue in higher education; administrators and students are expecting faculty instruction
to incorporate technology in classroom and distance education. Competition is demanding technologically proficient graduates
for schools and colleges. Research indicates that computer self-efficacy (CSE) may be one determinant of who uses technology
and who does not. A survey of education faculty at the Lebanese University in Beirut, Lebanon, conducted in 2006, revealed
varying degrees of CSE; of 127 respondents, 14 had low levels of CSE; 68 were at a moderate level, and 45 self-evaluated themselves
to have high CSE. Although other barriers may deter the implementation of technology in teaching, strategies and techniques
for increasing CSE should be developed. For those with low CSE, special attention must be given to enhancing their levels
of CSE.

Pregnancy is associated with significant, but reversible changes in thyroid function studies, which are among the most profound
seen as a result of a normal physiologic state. The present study was carried out to find out alterations in thyroid function
tests in each trimester in normal pregnant women as compared to non-pregnant women in Tabriz-Iran. A case-control study designed
with 229 normal pregnant women that randomly selected from the first (64 samples), the second (92 samples), and the third
(73 samples) trimesters and 250 randomly selected non-pregnant healthy female controls. Age range in both groups was 16–40
years. Thyroid function tests carried out by measuring serum levels of thyroid stimulating hormone (TSH), free and total thyroxin
(FT4, TT4), and free and total triiodothyronine (FT3, TT3) by commercially available radio immunoassay kits. We found that mean TT4 increased progressively during pregnancy. Our study showed increasing in serum levels of TT3 in the second trimester and then declining during the third trimester compared with non-pregnant women. We showed that FT4 strongly decreased during the third trimester. Free T3 showed declining in the second and third trimesters. Mean TSH did not show significant difference in each trimester compared
with non-pregnant women. The thyroid function tests in pregnancy should be interpreted against gestational age-related reference
intervals to avoid mis-interpretation of thyroid function during pregnancy. 相似文献

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan,and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards. 相似文献

This article explores the mono-cultural milieu of counseling. There are four primary contributors to the cultural domination of counseling by the Western culture. They are as follows: (1) the deep historical and philosophical roots of counseling in Western culture; (2) the dominant theories, practices and approaches of counseling make the assumption that counseling will take place within a Western culture; (3) the bulk of research and literature pertaining to counseling concentrates on counseling within the West; (4) the emulation by non-Western nations of Western models of counseling. The concept of cultural dissonance is given to help in the understanding of the relation of culture to a counseling relationship at a given time between counselor and client. 相似文献

In 1975/76 Kuwait University was transferred to an Elective System and initially, the article reviews the rationale and objectives of such a change. Guidance or advisement is considered a key means to achieve these objectives. The major focus of the article is an examination of several attempts to assess/evaluate the implementation and effectiveness of advisement. Recommendations for practical solutions to those problems which surround this practice are also discussed.Paper submitted to the International Consultation Conference on Career Guidance in Higher Education convened by IRTAC and Robinson College — Cambridge University, 13–17 December 1981, Robinson College, Cambridge, England. 相似文献

Collaborative inquiry learning affords educators a context within which to support understanding of scientific practices, disciplinary core ideas, and crosscutting concepts. One approach to supporting collaborative science inquiry is through problem-based learning (PBL). However, there are two key challenges in scaffolding collaborative inquiry learning in technology rich environments. First, it is unclear how we might understand the impact of scaffolds that address multiple functions (e.g., to support inquiry and argumentation). Second, scaffolds take different forms, further complicating how to coordinate the forms and functions of scaffolds to support effective collaborative inquiry. To address these issues, we identify two functions that needed to be scaffolded, the PBL inquiry cycle and accountable talk. We then designed predefined hard scaffolds and just-in-time soft scaffolds that target the regulation of collaborative inquiry processes and accountable talk. Drawing on a mixed method approach, we examine how middle school students from a rural school engaged with Crystal Island: EcoJourneys for two weeks (N=45). Findings indicate that hard scaffolds targeting the PBL inquiry process and soft scaffolds that targeted accountable talk fostered engagement in these processes. Although the one-to-one mapping between form and function generated positive results, additional soft scaffolds were also needed for effective engagement in collaborative inquiry and that these soft scaffolds were often contingent on hard scaffolds. Our findings have implications for how we might design the form of scaffolds across multiple functions in game-based learning environments. 相似文献
