记者年终个人工作总结范文多篇
一、基础扎实，视野开阔，才能够获得好的新闻角度 在今年的日常工作中，我对本市各大媒体的经济栏目都进行了细致的分析，摸准了我所跑银行的定位，同时我也意识到：我必需努力学习，争取能够以一名专业人士的视角来审视新闻。 厚积才能薄发，我通过业余时间恶补专业课程，同时阅读大量专业性报纸，观察优秀记者独特的视角、新闻切入点，同时认真阅读经济部同事的新闻报道。通过一段时间的观察，我认识到：好的经济记者必须具备举一反三，触类旁通的能力；必须具有充足的知识储备（新闻的敏感性是建立在广泛的知识储备的基础上的）。为了尽快达到这个目标，我做了大量的工作。 第一，我坚持收看中央电视台、x电视台的经济节目，从中了解金融基础知识和重点热点经济问题。 第二，我努力做一个有心人，注意身边人们谈论各类话题中有价值的东西，以备不时之需。记得在去年年初，我作为一个新记者，工作初期开展银行的新闻采写异常艰难，我通过阅读和观察，找到了一些颇具特色的新闻点，完成了20**年年初的一些理财稿件。
篮球教练年度个人工作总结范文多篇
一、“准确、快速、灵活”的意义及其关系。 “准确”是篮球运动中的一个突出矛盾，通常在比赛中因传球准确性差造成很多失误，或因投篮不准带来比赛的失败。篮球比赛本身攻守双方一切技术、战术的应用和对抗的焦点就是围绕解决能否干扰对方的一切行动的准确性并争取自己尽量多把球投入对方篮圈，因此，不难看出“准确”的重要。 快速”的目的是为了出其不意，攻其不备，可以造成以多打少；“灵活”是随机应变，克服不利条件，争取有利局势，没有“快”就没有“灵活”，“快”与“灵”为“准确”创造条件，保证“准确”的发挥，“快”与“活”是手段，“准确”是目的，反之，“准确”的动作缩短了时间，争取了速度，“准确”的投篮又逼使对方扩大防区，而对方防区的扩大，更有利发挥“灵活”和“快速”的特长。由此可见，“准确”是三者核心，应占首位。 二、在篮球队训练中的运用 我一直担任校男篮教练工作，通过几年来的实践，我在训练比赛中注意贯彻“准确、快速、灵活”这一指导思想，取得了显著的成绩。我校男篮在参加市级比赛中，多年保持前几名的地位。
护士个人工作报告总结范文多篇
之前常常为工作中的小事，因为不理解而情绪激动或是郁闷，但是随着时间的推移，我了解了也明白了许多：护士所做的工作就是护理患者，让患者受益，让患者满意，更要让患者尽快的康复！这就是我的工作！患者对我提出的意见那是我的不足，并不是他们无理的要求！如果连患者的需要我都没有了解到、没有及时地给予，那就是我的失职，更没有资格去谈工作的高尚了！只有患者的赞许才最高的荣誉！ 在护理工作中我们应该是“做”和“说”同时进行的，甚至有些时候“说”要比“做”来得更为重要。在与病人沟通中技巧占据着很大的因素，我们科的责任护士在这方面有着很深的“功力”，让人不得不服。 从工作中使我意识到护理工作要顺利展开，首先要取得患者信任，信任是双方交往的基础，是人和人之间最美丽的语言。在交流过程中，要讲究语言的艺术性，避免套用生硬的医学术语，善于使用非语言沟通技巧，运用亲切的目光，良好的言行举止，缓和患者因紧张造成的紧张心理，使患者积极配合治疗，最后获得双羸。 “信任”是我们护士和病人之间最好的桥梁，让我们把这座桥梁搭得牢固些吧，用我们的细心，获取患者的舒心！

精编个人学习红军长征精神心得体会与感受八篇
二万五千里长征，一次改变中国人命运的征程已在人们的评说中去过了大半个世纪。照现代社会这种急速更新换代的观念，早已是好几个时代过去了。按我们熟悉的某种号召“过去的就让它过去吧”。再说下去，就成了枭鸣似的烦扰，不免令人生厌。然而长征却不同。人们总在不断的言说、探究、拷问。我想或许是由于长征所代表的一种精神吧――一种全人类永恒追求的精神――坚持到底。 “红军不怕远征难”的精神！正因为这心中永存的信念，红军才有了“万水千山只等闲，五岭逶迤腾细浪，乌蒙磅礴走泥丸”的英雄气概！正因为这心中永存的信念，才有了“亲人送水来解渴，军民鱼水一家人”的温情！

大学生创业调研报告
浅阅读它是指一种浅层次的、以简单轻松娱乐性为追求的阅读形式。内容上，以无厘头式的消遣、娱乐或感官的刺激为上，充满了游戏精神及荒诞不经的色彩;方式上则以动漫、图像、影像等为主，文字为辅。相对于品茗式的传统阅读而言，这种快餐式文化追求的是横向的广度，即所谓的“碎片式的语言，拼盘式的内容”。 以“知道”代替“知识”，这样的快餐式、跳跃式、碎片式的浅阅读正成为大学生时下的阅读新趋势。为此，我们针对在校大学生开展了一次书面的问卷调研,以了解他们的思想状况和阅读需求,从而分析大学生素质的现状，并为进一步探索提高大学生素质参考依据。
