科技工作者时间分配和身心健康的现状及建议——基于长三角地区调查的实证分析

本文以长三角地区科技工作者时间分配和健康状况为研究对象.运用多元回归等方法,分析了883份长三角地区科技工作者的有效问卷.结果发现:当前科技工作者时间分配不合理、身心健康欠佳的情况严重,其中青年群体存在缺睡少动问题,高校教师和工程技术人员健康风险突出;时间分配和身心健康之间存在重要的交互影响,运动、睡眠、工作自主性等能提高身心健康水平,而压力、幸福感对工作时长、睡眠时间、工作自主性等分别有不同的影响.结合深度访谈、专家咨询等,课题组分析了时间分配不合理、健康状态欠佳的原因.最后从人才管理、科研管理、用人单位和社会环境四个方面,提出促使科技工作者提升时间管理和健康水平的对策建议.

The performance of Asian S&T journals in international citation indicators

This research explores the performance of Asian S&T journals based on the outcomes of various citation indicators. Indexed by Journal Citation Reports – Science Citation Index Expanded (JCR‐SCIE), journals published in China, Japan, India, Singapore, South Korea, and Taiwan between the years 2008 and 2012 are collected and analysed using bibliometrics and statistics methods. Results showed that the mean impact factor (IF) value of the journals from all countries was less than 1.3 throughout the period. Only journals from China and Japan had a mean IF or 5‐year IF (5Y‐IF) value exceeding 1. The self‐cited rate of the journals from South Korea remained the highest among selected countries but showed a declining trend every year. The self‐cited rates among journals from all the six Asian countries did not considerably affect the journals’ IF values. The results revealed that the IF‐based ranking factor (IF‐RF) of Chinese and Japanese journals in various subject fields constantly improved from 2008 to 2012, but this improvement trend was not observed in journals from the other four countries. Overall, the journals from Japan and China demonstrated stronger impacts than those from the other countries.     

Single cell kinase signaling assay using pinched flow coupled droplet microfluidics

Droplet-based microfluidics has shown potential in high throughput single cell assays by encapsulating individual cells in water-in-oil emulsions. Ordering cells in a micro-channel is necessary to encapsulate individual cells into droplets further enhancing the assay efficiency. This is typically limited due to the difficulty of preparing high-density cell solutions and maintaining them without cell aggregation in long channels (>5 cm). In this study, we developed a short pinched flow channel (5 mm) to separate cell aggregates and to form a uniform cell distribution in a droplet-generating platform that encapsulated single cells with >55% encapsulation efficiency beating Poisson encapsulation statistics. Using this platform and commercially available Sox substrates (8-hydroxy-5-(N,N-dimethylsulfonamido)-2-methylquinoline), we have demonstrated a high throughput dynamic single cell signaling assay to measure the activity of receptor tyrosine kinases (RTKs) in lung cancer cells triggered by cell surface ligand binding. The phosphorylation of the substrates resulted in fluorescent emission, showing a sigmoidal increase over a 12 h period. The result exhibited a heterogeneous signaling rate in individual cells and showed various levels of drug resistance when treated with the tyrosine kinase inhibitor, gefitinib.     

社会信息化测度体系中信息资源因素集的构建初探

本文从国内外信息化测度方法和模型,以及近年来我国学者进行的众多信息化测度实例出发,抽取信息资源因素,进行了归纳和总结。借鉴前人的研究成果,并依托一定的理论依据和现实依据,笔者构建了一个信息资源因素集,囊括传统文献信息资源（图书、报纸、期刊）和电子信息资源（广播、电视、网络）。该体系与现有的测度体系相比,具有更强的可靠性和较高的准确性,同时依然保持着较好的可操作性,因而是科学合理的。

Leadership supervision for managers of educational psychology services

A growing body of literature surrounds the development of effective supervisory practices for practitioner and trainee educational psychologists. To date, none of this has addressed supervision for managers of UK educational psychology services, despite evidence that they may be under increasing pressure to make difficult decisions, respond to changing economic and political contexts and experience greater scrutiny in relation to service performance. In this study, 10 principal educational psychologists (PEPs) took part in a focus group to explore the supervisory needs and experiences of service leaders. Emergent key themes revealed differential patterns of entitlement and support, with PEPs often reporting innovative practice in order to access supervision. Supervision often had a duality of purpose, with PEPs advocating and promoting service delivery, rather than seeking personal support, potentially eroding the notion of supervision as a “safe space.” Implications for future practice are discussed and a potentially supportive leadership supervision framework proposed.     

对当前科学技术期刊工作的几点认识

近半个多世纪，特别是近20年以来，科学技术的生产、传播和应用活动有序地发生了巨大的变革，说明这三者是一个有机的、互动共长的整体。科技期刊工作不论是宏观还是微观，都应当从这个整体出发考虑问题，这三者结合得越紧密越协调，科技期刊工作就越有成效。科技编辑人员在科学技术活动中扮演着选家、守门人、传播者的角色，一些促进科技活动的功能性社会机制也要编辑人员在编辑活动的过程中启动实施，因此，在新形势下应当高度重视编辑人才资源的开发，强化编辑队伍建设。现在我国科技期刊的运营规模狭小、分散，资金和技术力量薄弱，实现产业化、集团化已是大势所趋，不论哪种运营模式都应坚持社会效益第一的最高准则。
