The Micronesian client comes from a strategically important Western Pacific area that bears its own unique culture. To serve the Micronesian client more than adequately, the therapist needs an awareness and understanding of the culture of the Micronesians. The role their culture plays upon the development of the Micronesian and upon the psyche of the Micronesian is explored. 相似文献

This article seeks to trace the development of higher education in the Kingdom of Saudi Arabia from its origins to the present day. The study includes discussion of the historical roots of education as based on Islam, Islamic philosophy of education, the aims and objectives of higher education and modern university education. Empirical statistics are given to substantiate the Kingdom's rapid progress in higher education. Since 1957 when modern university education began with a single institution with twenty-one students and a staff of nine it has grown until twenty-five years later in 1982 higher education had grown to seven institutions with 63,563 students and a teaching staff of 6,906. The study examines these aspects of higher education; Saudi students studying abroad, foreign students studying in Saudi Arabia, female education, the role of the Ministry of Higher Education and the financing of higher education. 相似文献

The digital divide is severe in sub-Saharan Africa (SSA). The prevailing digital divide will continue to exist and define the characteristics of the digital information environment of the sub-region as it influences, along with other concerns, the information needs of end-users in the sub-region. The model of information needs of end-users in the electronic information environment and observations and theories from the literature of Library and Information Science (LIS) show that the information needs of end-users in SSA are for information content that is relevant for day-to-day tasks and that is adequately accessible and effectively usable within the capabilities of the information and communications technology (ICTs) that they possess and their level of skill in manipulating the ICTs. The model of the information needs of end-users in the electronic information environment presents the nature of user tasks, the state of electronic resources in use, and user experience in using the electronic resources as factors giving rise to information needs of end-users in a digital information environment. The principles of least effort, satisficing, utility and accessibility particularly give support to the argument of the paper: that end-users need information content that is adequately accessible and effectively usable within the capabilities of ICTs currently in use by the end-users concerned. Recognizing the nature of the information needs of the end-users of SSA will help in meeting their needs as well as in selecting appropriate interventions in addressing the digital divide in the sub-region. 相似文献

This study was aimed to compare the effects of acute and chronic psychological stress on metabolic factors. Forty-two male Wistar rats were divided into control and stressed groups. Stress was applied by a communication box acutely (1 d) and chronically (15 and 30 d). Blood sampling was carried out by retro-orbital-puncture method. The plasma levels of glucose, cholesterol, triglyceride, insulin, and corticosterone were measured. In addition, feed and water intake, latency to eat and drink, adrenal and body weights were determined. Acute and chronic psychological stress did not significantly change basal plasma corticosterone levels. However, immediately (1 min) after acute exposure to stress, plasma corticosterone level increased compared to that before stress exposure. Acute stress increased plasma insulin levels significantly. Fifteen days of stress exposure resulted in plasma glucose increase. Chronic stress significantly increased feed intake, latency to eat, and adrenal weight compared to acute stress. The body weights of both control and stressed groups increased markedly during the experiment. Homeostasis model assessment of insulin resistance (HOMA-IR) index did not change significantly in the stressed group. In conclusion, application of acute and chronic psychological stress leads to different metabolic and/or behavioral changes but the metabolic changes resulting from acute exposure to stress seem to be more pronounced. 相似文献

Currently, there is a growing belief that putting an IEEE 802.11-like radio into road vehicles can help the drivers to travel more safely. Message dissemination protocols are primordial for safety vehicular applications. There are two types of safety messages which may be exchanged between vehicles: alarm and beacon. In this paper we investigate the feasibility of deploying safety applications based on beacon message dissemination through extensive simulation study and pay special attention to the safety requirements. Vehicles are supposed to issue these messages periodically to announce to other vehicles their current situation and use received messages for preventing possible unsafe situations. We evaluate the performance of a single-hop dissemination protocol while taking into account the quality of service (QoS) metrics like delivery rate and delay. We realize that reliability is the main concern in beacon message dissemination. Thus, a new metric named effective range is defined which gives us more accurate facility for evaluating QoS in safety applications specifically. Then, in order to improve the performance, the effects of three parameters including vehicle's transmission range, message transmission's interval time and message payload size are studied. Due to special characteristics of the safety applications, we model the relationship between communication-level QoS and application-level QoS and evaluate them for different classes of safety applications. As a conclusion, the current technology of IEEE 802.11 MAC layer has still some challenges for automatic safety applications but it can provide acceptable QoS to driver assistance safety applications. 相似文献

This study reports the utilization of serum fructosamine and blood glucose for the screening of gestational diabetes mellitus
(GDM). Blood samples from 165 pregnant women were analyzed for fasting blood glucose (FBG), random blood glucose (RBG) and
serum fructosamine. The actual fructosamine levels were corrected for serum protein (c-Fruct) for more precise presentation.
Two cut-off values of FBG (>5.3 mmol/L and >7.0 mmol/L) and RBG (>7.8 mmol/L and >11.0 mmol/L) were used to classify hyperglycemic
subjects for subsequent evaluation. The average values±standard deviations for FBG, RBG and cFruct were 5.865±1.95, 7.767±3.21
and 2.387±0.47 mmol/L, respectively. FBG levels were significantly correlated with RBG (Pearson correlation=0.597, P<0.001).
Significant correlations were also observed between cFruct and FBG (Pearson correlation=0.673, P<0.001) or RBG (Pearson correlation=0.641,
P<0.001). Out of 165 subjects, 24 (14.5%) cases were classified as hyperglycemic on the basis of FBG>7.0 mmol/L or RBG>11.0
mmol/L; use of lower cut-off values resulted higher frequencies of hyperglycemia. Whereas, a combined criteria of FBG>5.3
mmol/L and cFruct >2.5 mmol/L predicted 35 patients as the most probable hyperglycemic as compared to 32 patients identified
using the criteria of RBG >7.8 mmol/L and cFruct >2.5 mmol/L. These criteria were associated with 4.8% and 3.6% false-positivity
at the expense of 3.6% and 3.0% false-negative outcomes, respectively. The levels of FBG, RBG and cFruct were significantly
higher in hyperglycemic groups (irrespective of grouping criteria) as compared to the respective normal groups. In conclusion,
these findings clearly indicate that the paired values of cFruct with FBG or RBG could help in filtering high-risk individuals
for OGTT and therefore avoiding a unnecessary OGTT. 相似文献

In this paper, a new homomorphic image watermarking method implementing the Singular Value Decomposition (SVD) algorithm is presented. The idea of the proposed method is based on embedding the watermark with the SVD algorithm in the reflectance component after applying the homomorphic transform. The reflectance component contains most of the image features but with low energy, and hence watermarks embedded in this component will be invisible. A block-by-block implementation of the proposed method is also introduced. The watermark embedding on a block-by-block basis makes the watermark more robust to attacks. A comparison study between the proposed method and the traditional SVD watermarking method is presented in the presence of attacks. The proposed method is more robust to various attacks. The embedding of chaotic encrypted watermarks is also investigated in this paper to increase the level of security. 相似文献
