Palestine is a small newly established state in the Middle East. The objective of this study was to assess the quantity and quality of research output from Palestine after Oslo peace accords. The data used for this study were retrieved from Scopus database (officially known as Sciverse Scopus). Bibliometric analysis was used to identify the pattern of publication, relative growth rate, authorship pattern, collaborative measures, author's productivity, most prolific authors, and most prolific journals. A total of 3,585 published documents were retrieved from Palestine. A steady increase was observed after 2001. The h-index of the retrieved documents was 57. Fifty-three (1.48%) documents were published in Eastern Mediterranean Health Journal, whereas 52 (1.45%) and 49 (1.37%) documents were published in Journal of Dispersion Science and Technology and Asian Journal of Chemistry, respectively. Half of the top 20 journals in which Palestinian researchers had published their articles were un-indexed in Institute for Scientific Information (ISI) web of knowledge. The highest number of documents published by a Palestinian researcher was 79. The main subject area of published documents from Palestine was medicine (717; 20.00%), followed by chemistry (551, 15.37%), and engineering (530, 14.78%). The top countries involved in research collaboration with Palestine were the United States (422, 11.70%), followed by Germany (381; 10.71%), and the United Kingdom (208; 5.83%). There was a significant correlation between number of collaborating countries with Palestine in one hand, and quantity and quality of research activity in Palestine on the other hand. The number of collaborating countries with Palestine increased almost ten-fold from 1995 to 2012. Research output from Palestine showed steady growth since the Oslo peace accords. Research output was high from certain scientific disciplines while was lagging from others. Future emphasis on joint research, international collaboration, and publishing in indexed journals is needed.  相似文献

This study is an attempt to evaluate the effectiveness of electronic resources and services in Pakistani university libraries on the basis of users' satisfaction. A survey method was employed to conduct the research. Using convenience sampling, eight university libraries; four each from Islamabad and Lahore including two from the public sector and two from the private sector having IT applications, were included in the users survey. The total population (i.e., 40,236) of library users was very large; therefore, a reasonable, manageable and convenient sample of 800 library users, including 100 users each from the eight libraries was selected. A semi structured questionnaire was designed to collect data, while a five-point Likert Scale from 1 (Dissatisfied) to 5 (Extremely satisfied) was used to measure the satisfaction level of the respondent. The study concluded that Pakistani university libraries are offering effective electronic resources and services to their users.  相似文献

民国时期,我国公文称谓格式的演变是一个由繁趋简的过程,一个由各行规则到趋于一律的过程:公文称谓词大量减少,公文自称被划一;公文署名程式也逐渐走向统一。这个趋于一律的演变过程,反映了公文礼仪让位于效率的实质,折射出我国公文工具化、平等化的现代化精神。  相似文献

The impact of two models of induction into library services, a “one stop” orientation model and an “active learning” model with task-specific coaching, was assessed. The study was conducted with participants on a Continuing Professional Development course and a pre-Initial Teacher Education course. Questionnaire data showed differences between the groups in terms of information seeking behaviors and the sources they used A simple indicator of efficacy of information retrieval and evaluation was derived from participants’ assessed work reference lists, which was indicative of different outcomes from the two induction processes.  相似文献

ABSTRACT

Adsorbent materials can be used for the removal of organic acids from air in storage rooms with heritage collections. The organic acid removal efficiency of two commercially available activated carbon air-filters were tested in situ in two unoccupied stores with densely packed collections. One filter was designed for outdoor type pollutants (Filter A), while the other was designed for organic acids in indoor air (Filter B). Furthermore, the acetic acid removal efficiency of a desiccant silica gel rotor used for dehumidification was measured in a laboratory at different relative humidity levels. Finally, passive removal of acetic acid by silica gel and unfired clay brick were tested in a chamber, and for clay brick at room level as well. Filter B had the highest removal efficiency. The removal efficiency of both filter types depended on the airflow and the filter performance varied considerably in situ from the values reported from standard laboratory tests. Increasing the filter airflow reduced the removal efficiency from 77% and down to 7% for Filter A, and from 92% to 24% for Filter B. There was almost no effect of active air filtration on the concentration of organic acids when this was measured in the middle and in the corner of the storage rooms away from the ventilation inlets. The desiccant dehumidifier removed 98–100% of the acetic acid from the air, independently of the relative humidity. The desiccant rotor will, however, only be running when there is a need for dehumidification and as a result will only periodically remove pollutants. The high acid removal efficiency by dry silica gel was furthermore demonstrated in a chamber test. A clay brick wall in a test room established a concentration gradient across the room and reduced the concentration of organic acids by 56% compared to close to the emission source.  相似文献

This study examined the argument patterns that result when Israeli-Jews and Palestinians confront each other during group dialogues. We tested predictions derived from two theories. The first was a theory of cultural communication which predicted that Israeli-Jews and Palestinians would argue in a manner consistent with their respective cultural communication codes known as dugri and musayra respectively. Thus, the Israeli-Jews were expected to be assertive and the Palestinians more accommodating. The second theory was rooted in majority/minority power relations and predicted the opposite. The data were generated from reconciliation-based dialogue groups of Israeli-Jews and Palestinians. Communicative acts were coded according to the Conversational Argument Coding Scheme. Analysis of covariance was used to determine which patterns of argument distinguished the groups, and to identify variance attributable to lag sequences and individuals. The results were supportive of predictions from majority/minority power relations.  相似文献

从Brookes文献老化的负指数方程出发,推导出引文半衰期和普赖斯指数之间的关系式,证明他们之间不是反比关系,并用此关系式重新拟合了陈立新等人的数据。拟合结果表明:该关系式可以很好地拟合1954-1968年的数据,拟合1969-2003年的数据则出现较大的偏差。其原因可能是随着科学技术的进步,SCIE力学专业期刊的引文半衰期对普赖斯指数的变化率比理论值要快。此外,拟合结果还揭示SCIE力学期刊中的经典文献的引文半衰期在较长时间内是不变的。  相似文献
