推进城镇化、降低房价与房地产去库存——对我国35个大中城市的经验分析

推进城镇化和降低房价被认为是当前我国房地产去库存的主要措施.利用2001-2013年35个大中城市的数据实证检验推进城镇化和降低房价对房地产去库存的影响,结果表明:从整体上来讲,推进城镇化和降低房价确实能够有效消化当前我国过剩的房地产库存;但也表现出明显的地区差异,东部地区推进城镇化的作用明显但降低房价的作用有限,中西部地区降低房价的作用显著而推进城镇化的作用有限;此外,提高人均收入对房地产去库存也具有积极影响,而地方财政收入越高、人口密度越大的地区房地产去库存的压力越大.因此,房地产去库存应因地制宜,要根据各城市的房地产市场情况制定切实可行的政策,实现精准调控.     

Postpartum Mothers’ Leisure-Time Exercise Behavior is Linked to Positive Emotion During Partner Discussions

Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of mothers’ exercise during the postpartum period were related to more positive and fewer negative emotion-expressive behaviors with their infants’ fathers. Method: Mothers’ (N = 46; M = 8 months postpartum) positive and negative expressive behaviors were coded during couples’ discussions of current conflict and positive family experiences. Mothers self-reported their leisure-time exercise behavior. Results: First-time mothers and mothers with higher levels of leisure-time exercise behavior displayed higher levels of positive expressive behaviors during couples’ discussions. Conclusions: Exercise may be associated with increased positive emotion and, in turn, can have great potential to improve family relationships during the postpartum period when marital stress normatively increases, particularly for mothers with more than 1 child. Future longitudinal studies are needed to understand exercise patterns across the postpartum period to identify the most effective timing and optimal level of exercise that lead to more positive expressive behaviors.

‘We Will Try Again,Again, Again to Make It Bigger’: Japan,American Football,and the Super Bowl in the Past,Present, and Future

Abstract

This study is to analyse how the Japanese have traditionally received and currently perceive the Super Bowl, and for this purpose, it aims to locate the position of American football in Japanese history, society, and culture. It explores the game’s history and then examine the degree of its spread among Japan’s sporting population. A two-dimensional approach of historical study and inter-game comparison gives context to the analyses of reference frequency and contents of news media, followed by speculative discussions of what the near future of Japan’s American football would be like. To conclude, it clarifies the ways the Super Bowl has been received and is now being perceived by two groups: The first group is the general people who see the Super Bowl as the convenient and useful medium by which they could learn effectively about American culture through the one-night mania for ‘conspicuous consumption’. The second group comprises American football experts and enthusiasts, including 13,000 athletes and their OBs, coaches, trainers, and other staff members of the leagues and associations as well as the general sports fans. For this group, the Super Bowl is the apex of their favourite sport to which only a selected talented few could join.

Acerca del hielo en el islam medieval

The history of ice in medieval Arab societies is obscured behind a mosaic of a variety of references and scholarly citations. Beyond al-Qalqashandī's reference to organised ice trafficking in fourteenth-century Mamluk Egypt, we do not have conclusive evidence on the origin and use of ice as a consumer product. In this paper we trace its presence based on three genres of references: historical and literary quotations, medicine and literature pertaining to food. These references allow us to consider the extent of ice consumption in the Arab world before the ninth century, as well as the existence of an organised trade throughout the Middle Ages from that time. However, contrary to the Persian world, with its well-documented Iranian yakhchals, we still know virtually nothing about ice-houses in medieval Arab societies. We also know very little about the profession of the thallāj or ice-seller, or whether the widespread consumption of ice that originated in Spain in the sixteenth century was in fact a legacy of an earlier trade in al-Andalus.     

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.     

National nostalgia: A group-based emotion that benefits the in-group but hampers intergroup relations

Social psychological research on nostalgia has mainly considered this emotion at the individual level rather than the group level. The current paper proposes that group-based nostalgia for the nation (i.e., national nostalgia) is likely to be related to a positive in-group orientation and a negative out-group orientation, because it fosters an exclusionary and essentialist sense of national identity that is based on ancestry and common descent (i.e., ethnic national identity). This prediction was tested in three survey studies. Study 1 was conducted among a broad sample of the native Dutch population, and demonstrated that national (and not personal) nostalgia is positively related to national in-group identification and out-group prejudice. Study 2 replicated the findings of Study 1 among a nationally representative sample of the native Dutch population, and provided support for the mediation by ethnic national identity. Study 3 replicated the findings of Study 2 and additionally demonstrated that national nostalgia positively predicts tendencies to protect national in-group identity, via a stronger sense of ethnic national identity. These findings demonstrate the potential of group-based nostalgia to have positive and negative consequences for group dynamics at the same time.     

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.
