新兴技术往往具有很大的不确定性、风险性和模糊性,在此情况下,新兴企业如何进行技术整合、探索新的技术领域;更具体地,这些企业如何构建自己的技术空间,到底是应该和行业的技术空间保持一致性呢,还是保持差异性?本文聚焦于"新兴企业如何构建技术空间"这一问题,从企业技术能力及其组合的角度切入,以489家战略性新兴产业企业为样本,研究发现,在不同的企业技术能力组合情境中,企业-行业的技术空间异质性对企业绩效具有差异化的影响。具体而言,在核心技术能力高、一般技术能力高的情境中,技术空间异质性对新兴企业绩效有显著的正向影响;在核心技术能力高、一般技术能力低的情境中,技术空间异质性与新兴企业绩效间呈倒U型关系;在企业核心技术能力低的情境中,无论新兴企业的一般能力是高还是低,技术空间异质性对新兴企业绩效均有显著的负向影响。本文的研究从技术能力组合的视角拓展了技术空间异质性的研究,也为新兴企业的技术空间构建问题提供启示。  相似文献

The rise of the Mongol empire was a shock to the Arab world and led many Arab authors to describe these conquerors in decidedly negative terms. The great historian Ibn Khaldūn also discusses the Mongols' rise and their conquests. As a nomadic people they challenged and defeated sedentary populations and founded their own dynasties. Consequently, the Mongol conquests perfectly fit Ibn Khaldūn's theories on ?a?abiyya – which is superior in nomadic groups – and the rise and fall of dynasties. For the Maghrebi historian, the rise of the Mongols was a natural step in the course of history. This consequently colours his view of the Mongols and affects the way he portrays them, especially regarding the themes of violence and religion – recurring themes in many contemporary works dealing with the Mongols – and in his depiction of the Turco-Mongolian conqueror Timur, who is presented in a more favourable light by Ibn Khaldūn than he is in many contemporary works.  相似文献

This article examines the frontier between the Seljuk Sultanate of Rūm and its Byzantine neighbours in the thirteenth century, concentrating on the place of these frontier districts within the Seljuk state. Scholarship on the frontier, influenced by the ideas of Paul Wittek, has seen it as something of a “no man's land”, politically, economically, culturally and religiously distinct from the urban heartland of the Seljuk sultanate in central Anatolia, dominated by the nomadic Turks, the Turkmen, who operated largely beyond sultanic control. It is often thought that the Seljuk and Greek sides of the border shared more in common with each other than they did with the states of which they formed a part. In contrast, this article argues that in fact the western frontier regions were closely integrated into the Seljuk sultanate. Furthermore, with the Mongol domination of the Seljuk sultanate in the second half of the thirteenth century, the Seljuk and Mongol elites became increasingly involved in this frontier region, where some of the leading figures of the sultanate had estates and endowments.  相似文献

This is the second of two articles by the same author arguing against the thesis that there was a conspiracy between the Byzantine emperors and Saladin, sultan of Egypt and Syria, against the crusader states and the Third Crusade in the 1180s. While the focus of the first article was primarily on the Latin sources, the present study shifts the focus to the Arabic primary material, hitherto largely neglected or inadequately treated by modern historians. Through a critical re-examination and re-interpretation of the Arabic sources, backed by the introduction and discussion of new Latin material when necessary, this article presents expanded arguments on the relations between the Byzantine Empire, the Sultanate of Konya and Saladin in the 1180s. The conclusions lend further support to the view that the Byzantine rulers and Saladin never concluded an alliance against the Latin settlers of Outremer and the Third Crusade.  相似文献

ABSTRACT

Traditionally Māori attributed disease to supernatural causes, including mākutu (sorcery) and, as with some other indigenous cultures, considered that killing sorcerers was both just and right. Belief in mākutu ran counter to the Church's desire to gain religious primacy, and mākutu-related murders challenged the State's claim to sovereignty, and its desire to ‘civilize’ Māori. Each indigenous society possesses unique characteristics, just as the nature of each settler society develops within its own environment. While some similarities with other colonized societies can be identified, distinctive local conditions influenced the relationship of Māori to the New Zealand colonial state, and thus attitudes and actions relating to sorcery-related crime. This article explores how mākutu brought Māori communities into conflict with both Church and State, and how the latter in particular was constrained by political realities. As the nineteenth century came to an end, the murders had largely ceased and the State and Church became more concerned with Māori spiritual healers. The article also shows that Māori reformers in the late nineteenth and early twentieth centuries took a lead in changing Māori attitudes.  相似文献

This article examines the presentation of Muslim rulers from the early crusading period, 490–540/1097–1146 in six of the main chronicles written during the first half of the seventh/thirteenth century. It discusses the themes, ideas and topoi in each, demonstrating that the historians appear to have been divided into two ‘camps’ over their presentation of these rulers, based on their personal views of the rulers of their time. The article also examines why this division may have occurred, and considers its ramifications for modern scholarship of Arabic historiography, Islamic history and the history of the Crusades, in both the sixth/twelfth and seventh/thirteenth centuries.  相似文献
