The independence of editorial content from advertisers' influence is a cornerstone of journalistic ethics We test whether this independence is observed in practice. We find that mutual fund recommendations are correlated with past advertising in three personal finance publications but not in two national news- papers. Our tests control for numerous fund characteristics, total advertising expenditures

Media and especially mass media like newspapers or magazines are characterised by a number of peculiarities which are interesting from both a theoretical and empirical point of view. The interrelationship of reader

Numerous empirical studies have demonstrated that asset prices react rapidly, if at all, to news published in the mass media. In many cases, the information has been discounted and prices have already moved upon primary publication through news wires, press releases or firm announcements. Any remaining information is usually quickly priced in after

This article considers how professionals \think by doing\and provides theoretical rationale for reflective practice as a model for teaching journalism. It presents a model focused on the development of graduate efficacy in the intellectual skills and understanding required of professional practitioners. The model uses critical reflection as a cognitive bridge between journalism theory and professional

一、选择题:(单项选择题,将合适的答案填在括号内)(40分) 1.称样量约为0.2g,要求称量相对误差为0.1%,应选用哪种天平。 (A)万分之一的分析天平; (B)十万分之一的微量分析天平; (C)千分之一的工业天平

概述：热处理工艺一般由加热、保温和冷却三个阶段组成，其目的是为了改变金属或合金的内部组织结构，使材料满足使用性能要求。除回火、少数去应力退火，热处理一般均需要加热到临界点以上温度使钢部分或全部形成奥氏体，经过适当的冷却使奥氏体转变为所需要的组织，从而获得所需要的性能。奥氏体晶粒大小、形状、空间取向以及亚结构，奥氏体化学成分以及均匀性将直接影响转变、转变产物以及材料性能。奥氏体晶粒的长大直接影响材料的力学性能特别是冲击韧性。综上所述，研究奥氏体相变具有十分重要的意义。本章重点：奥氏体的结构、奥氏体的形成机制以及影响奥氏体等温形成的动力学因素。本章难点：奥氏体形成机制，特别是奥氏体形成瞬间内部成分不均匀的几个C%点，即C1、C2、C3和C4
