    全像圖組織設計運用於危機管理之研究--以警察組織處理紅衫軍倒扁行動為例

    No full text
    我國自詡為世界上最民主的國家之一,但大規模的政治性群眾事件常讓國人生活受到巨大的影響,其中的平衡點不易拿捏。姑且不論民主是如何的被定義,主要的特色之一,就是其不確定性。民主政治正是嘗試以一套複雜的程序機制,儘可能誠實將衝突與不完美暴露出來,並不斷尋求協商妥協的政治體制。本研究認為社會上龐大的情緒能量需要宣洩的管道,而群眾活動則是最佳的情緒出口。 警察扮演著社會秩序維護者的角色,而警察機關往往將群眾事件列為組織外部的重大危機。蓋因大規模的群眾抗爭事件易牽涉到政治層次,若處理不慎,將引起流血衝突與造成社會不安,警察亦將成為眾矢之的或淪為政治角力下的犧牲者。而本研究嘗試結合危機管理理論及全像圖組織設計之概念,輔以實證方式探討警察組織面對「紅衫軍」此一大規模政治性群眾運動之作為與實際產生之影響,發掘理論上與實務上問題,據以提出相關建議。 本研究廣泛蒐集有關危機管理、群眾活動、全像圖組織設計等理論論述文獻與研究資料,並藉由報紙、雜誌及網路等工具蒐集「紅衫軍倒扁行動」之個案資料。此外,為增加本研究之廣度與深度,亦對實際面對、處理紅衫軍活動的警察組織不同層級人員與紅衫軍群眾進行深度訪談,以獲得第一手之資料。 本研究共分六章,第一章指出研究動機、研究目的與研究問題、研究範圍與限制並對重要名詞作出界定。在第二章,回顧群眾活動與危機管理的基本概念與意涵,從而建立起本研究的基本知識架構,並透過對危機管理、群眾活動及全像圖組織等領域相關期刊論文及碩博士論文之檢閱,瞭解相關領域所作研究之知識前緣。而於第三章,本研究藉由探討危機管理理論並結合警察實務現況,歸納出可由領導決策、組織運作、策略規範等三個面向來落實危機管理之具體實踐,該章亦對本研究爰引全像圖組織設計概念的思考過程,及有關全像圖組織設計理論重點進行深入說明與探討。 第四章說明本研究之研究方法與研究流程、研究架構及研究設計。而第五章先對紅衫軍倒扁行動作概略性的描述,並由訪談結果描繪出警察組織在紅衫軍倒扁行動上之處置作為及警察組織與紅衫軍之互動關係。第六章為本研究之結論,除提出理論上、實務上及有關警察組織在危機管理機制建構上的研究發現外,並對於本研究較不足之處提出檢討與建議,以作為後續研究之參考

    用电弧离子镀膜技术通过改变N2流量的方法,在质子交换膜燃料电池(PEMFC)中用不锈钢双极板表面沉积一系列不同N含量的CrNx改性薄膜,对薄膜的成分、结构与接触电阻、耐蚀性能进行了测试。结果表明,沉积CrNx薄膜能够明显改善双极板的表面性能,并且其性能随着薄膜中N含量的变化而变化。与原始不锈钢相比,接触电阻降低1个数量级,耐腐蚀性能提高2个数量级。其中N含量为46.2%时,接触电阻降低到了11.8mΩ·cm^2(0.8MPa夹紧力);N含量为50.5%时,极化电流降低到10^-7A/cm^2(电极电位为0.6V)。分析表明,双极板处理后性能的改善与电弧离子镀薄膜的致密度较高,以及薄膜的成分、结构随薄膜中N含量的变化有关

    为建立快速鉴别橄榄油掺假的检测方法,以特级初榨橄榄油、玉米油、猪油、牛油和鸭油为实验材料,通过元素分析-稳定同位素质谱仪测定油脂的δ13C、δ18O和δ2H,并结合化学计量学鉴定橄榄油掺假。采用主成分分析(PCA)和正交偏最小二乘法判别分析(OPLS-DA)两种统计分析方法建立不同油脂的鉴别模型和橄榄油掺假鉴别模型。结果表明:橄榄油的δ13C、δ18O和δ2H范围分别在-30.411×10-3~-28.996×10-3、23.583×10-3~25.581×10-3、-163.611×10-3~-132.251×10-3 之间;橄榄油与玉米油、猪油、牛油和鸭油的OPLS-DA鉴别模型准确性稍好,3个变量δ13C、δ2H和δ18O对不同油脂区分的贡献度VIP值分别为1.056、0.997和0.943;使用其他4种油脂对橄榄油进行掺假时,OPLS-DA鉴别模型可明显区分橄榄油与掺假油;PCA-Class鉴别模型对橄榄油掺入玉米油、猪油、牛油和鸭油的检测限分别为5.8%、5.6%、6.4%和12.5%,盲样验证鉴别准确率可达100%。该方法所构建的鉴别模型准确可靠,可有效识别橄榄油中掺入玉米油、猪油、牛油和鸭油。 To establish a rapid detection method for the adulteration of olive oil,extra virgin olive oil, maize oil, lard, beef tallow and duck fat were used as materials, and an elemental analysis-stable isotope ratio mass spectrometer determining δ13C,δ18O and δ2H couple with chemometrics was established to identify olive oil adulteration. Two statistical analysis methods, principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA), were used to establish identification models for different oils and olive oil adulteration. The results showed that the δ13C,δ18O and δ2H of olive oil range from -30.411×10-3--28.996×10-3, 23.583×10-3-25.581×10-3 and -163.611×10-3--132.251×10-3, respectively. The accuracy of the OPLS-DA identification model of olive oil, maize oil, lard, beef tallow and duck fat was slightly better. The VIP values of δ13C, δ2H and δ18O were 1.056, 0.997 and 0.943, respectively. When adulterating olive oil with the other four kinds of oils, the OPLS-DA identification models could clearly distinguish olive oil from adulterated oil. The limits of determination of maize oil, lard, beef tallow and duck fat adulterated in olive oil were 5.8%, 5.6%, 6.4% and 12.5% respectively by PCA-Class model, and the test sample verification accuracy could reach 100%. The identification models constructed are accurate and reliable, and can effectively identify the adulteration of maize oil, lard, beef tallow and duck fat in olive oil
