对我国优秀田径运动员过早退役原因的调查分析

通过问卷、访谈等方法对我国田径运动员的过早退役原因做了调查分析。结果表明:运动损伤、后顾之忧、收入偏低、潜力不大是造成过早退役的主要原因;与教练关系不和及其他两方面对退役的影响相对没有前几项大。值得注意的是绝大多数都是由于主要原因综合所致。另外,对出现这些原因的根源也作了具体的探讨。     

The Jews of Venetian Candia: The Challenges of External Influences and Internal Diversity as Reflected in Takkanot Kandiyah

Takkanot Kandiyah is a collection of Hebrew-written legislative texts regarding the leadership of the Jewish community of Candia, the capital of the Venetian colony of Crete, which were issued by successive generations of communal leaders between the early thirteenth and late sixteenth centuries. The detailed information it provides on many areas of the communal life makes Takkanot Kandiyah a valuable source for historical research into Jewish life in the medieval and Early Modern Mediterranean. Through a study of the texts contained in Takkanot Kandiyah, this article attempts to identify and analyse the ways in which the leadership of the Candiot community responded to the challenges of coexistence with the Greek inhabitants of Crete and the Venetian rulers of the island, as well as with the Jewish immigrants whom the currents of history brought to Crete from various corners of the Mediterranean, and thus to examine the importance of the “Mediterranean dimension” of the life of Cretan Jewry.     

The Seljuk Sultanate of Rūm and the Turkmen of the Byzantine frontier, 1206–1279*

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.     

The Saljuq Turks’ Conversion to Islam: The Crusading Sources

This article contributes to the important debate over the conversion of the Turks to Islam. Previously, it was thought that the Turks abandoned their former steppe faith and customs very swiftly to become staunch Sunni Muslims, but this view has recently been challenged by a number of studies. The current consensus seems to be that the Turks’ adoption of Islam was a process of far longer duration, spanning many decades. This article broadens this discussion by demonstrating that the chronicles written by the First Crusaders contain much useful information that is pertinent to this question. It works through these texts, showing that they can shed new light on this point.     

People's media and communication rights in Indonesia and the Philippines1

This article attempts to investigate the emerging people's media in relation to the development of communication rights in Indonesia and the Philippines. The thrust is to focus on how the Indonesian and Philippine press acquiesced to political and economic control by the governments of the dictatorial regime of President Soeharta and President Marcos. On the other contrary, we look at how people felt that communication rights are their basic rights and that freedom of thought and freedom of speech are essential for democratic rule. Their resistant to violence, imprisonment and murder carried out by state functionaries have brought new forms of media. These are people's media or radical and citizen media which empower as well as transform ‘passive citizens’ into ‘political actors’.     

An Examination of Media Usage among French-Muslims

Media help in the formation of identity. For ethnic communities, ethnic media can play a dual role, aiding in the acculturation process and assisting in holding onto ethnic identities. This study examines media and identity negotiation. Specifically, this study analyzes differences in media usage among French-Muslims. The principal researcher interviewed 42 first and second generation French-Muslims to explore their media usage and the relationships between their media usage and ethnic identification. Analysis uncovered two key findings. First, second-generation French-Muslims prefer to use ethnic media more than French produced media as a form of protest against French assimilationist policies. Second, abandoning ethnic media is equated with becoming French, which is something first and second generation French-Muslims resist.     

“Fear God; Fear the Bogaze”: The Nile Mouths and the Navigational Landscape of the Medieval Nile Delta,Egypt

By the fourth/tenth century, Egypt's Nile Delta had just two major Delta branches debouching directly into the Mediterranean – the Dumyā? (Damietta) and Rashīd (Rosetta). Navigational conditions at these branches’ mouths were treacherous because of a combination of currents, winds, wave-fields and shifting sandbanks. These conditions were a danger to shipping, and so had a formative effect on the navigational landscape of the Delta. Despite its remoteness from the Nile, Alexandria remained Egypt's chief Mediterranean port, but only because river connections were maintained that avoided the Rashīd mouth. In contrast, the port of Rashīd was relatively insignificant. Similar conditions at the Dumyā? mouth prompted navigators to adopt routes via Lake Tinnīs, modern Lake Manzala, which linked to the sea through its calmer sea mouths. This article brings together material from multiple disciplines to offer a new understanding of the navigational context of Egypt's medieval Mediterranean ports.
