器材引入作为实验教学中的一个环节,长期以来没有受到教师们的足够重视。教师们习惯于在实验教学中将器材直接呈现给学生,让学生“解释”器材的结构或作用,这种器材引入方式的弊端是学生被教师牵着鼻子走,思维受到了限制,基本不需要动脑。为了培养学生的科学思维,实现学科的育人目标,提出器材引入要多一些“建模”少一些“解释”。从这个观点出发,从测量器材、演示器材、分组器材中各选一例,先介绍器材引入的常规教法,在分析点评的基础上,给出这几例器材引入的优化教法,通过对比和反思,总结出了器材引入的几点建议。

韦伯在《新教伦理与资本主义精神》中对现代资本主义的起源提供了一个精神层面的解释,即认为新教的伦理促进了资本主义精神的产生,在这种精神作为动力的推动下,现代资本主义开始发展,但是韦伯也发现,随着时间发展推移,资本主义丧失了资本主义精神,可失去了宗教层面的精神动力推动的资本主义仍在强劲发展,仿佛有一套自己的秩序,将整个社会都纳入其中。韦伯认为,这是理性化发展的结果,理性化推动了资本主义的发展,但也使资本主义精神逐渐被湮灭,最终发展成理性化的资本主义经济秩序将现代社会铸成一个“铁笼”。韦伯在研究现代资本主义的起源、发展的同时,也表达出对现代社会的高度理性化的担忧。

冷鲜羊肉新鲜度受多种因素影响,可通过多个理化和微生物指标综合评价。传统检测方法操作复杂、效率低。高光谱成像作为一种快速且非破坏性的检测技术,可以有效地检测冷鲜羊肉新鲜度改变过程中不同成分的变化。为了研究采用高光谱成像技术实现冷鲜羊肉新鲜度多指标评价的可行性,提出一种改进人工神经网络算法,通过重新定义损失函数加强标记之间的相关性,充分采用多个新鲜度指标对冷鲜羊肉新鲜度分类。试验收集了0~14 d冷鲜羊肉样本在400~1000 nm范围的高光谱图像,采用实验室方法测定挥发性盐基氮(TVB-N)、pH值、菌落总数(TAC)和大肠菌群近似数(ANC)指标值。通过S-G平滑滤波法和多元散射校正对冷鲜羊肉样本原始光谱数据进行预处理,采用连续投影法(SPA)选择光谱数据的18个特征波长作为输入数据,采用所提出的改进人工神经网络算法建立多指标冷鲜羊肉新鲜度等级模型。结果表明,改进人工神经网络对测试集的分类准确率达96%,三个新鲜度等级样本的识别率分别为100%、89.28%和98.68%,采用汉明损失(hamming loss)、1-错误率(one-error)、排序损失(ranking loss)和覆盖率(coverage)四种多标记模型指标进行评价,评价指标分别为0.008、0.002、0.0025和4.048。改进人工神经网络分类模型的准确率和各项模型评价指标均优于传统ANN,证明改进人工神经网络用于多指标冷鲜羊肉新鲜度的无损检测具有可行性。

基于TOE框架,以51家国内工程机械上市公司为案例,采用fsQCA方法,从组态视角探析7个前因条件对数智化转型的组态效应。结果表明,单一要素不是工程机械企业取得数智化转型高绩效的必要条件,数智化转型高绩效是技术、组织及环境等多种因素共同作用的结果,数智化转型高绩效实现路径有四种,分别是市场竞争型、市场-研发型、环境引领型、多因素组合型,即便缺失某个因素,工程机械企业数智化转型绩效也未必低下,其它因素可弥补相应不足。
