女作家身心分裂的抒写——论郝思嘉和媚兰的形象意义

郝思嘉和媚兰是玛格丽特·米切尔的小说《飘》中塑造了两位出色的女性人物形象。她们个性各异并形成鲜明的对比,在这种对比中,尤其突显了郝思嘉热爱金钱的现实主义性格与媚兰道德至上的理想主义追求。正是从这样的人物角色的安排中,我们看出了作家自身的身心分裂：既认同郝思嘉自强自立的女性主义意识,又无法真正摆脱男权社会传统的道德价值观。

Gesellschafterausstieg in großen Familienunternehmen

Zusammenfassung  Dieser Beitrag befasst sich mit dem Ausstieg von Gesellschaftern aus Familienunternehmen als bedeutendes Corporate Governance-Problem. Im Mittelpunkt steht die Untersuchung der Wirkung von Ausstiegsmotiven, Rahmenbedingungen sowie Ausstiegsbarrieren auf die Belastung von Unternehmen und Familie durch den Gesellschafterausstieg. Eine explorative empirische Untersuchung von 55 gro?en deutschen Familienunternehmen liefert Ans?tze für eine Organisationstheorie des Familienunternehmens und für praktische Empfehlungen bei der Gestaltung von Satzung und Ausstiegsverhandlung.

Summary  This article deals with the exit of shareholders in family owned businesses as an important corporate governance problem. We mainly analyse the effect of exit motivations, exit conditions, and barriers to exit on the exit’s burden for the company and the family. An explorative empirical study of 55 large German family owned businesses comes up with ideas for an organization theory of family owned businesses as well as some practical recommendations for statutes and exit negotiations.

     

Moderate wage increases and flexible labour contracts to protect employment in Colombian manufacturing

Based on conditional and unconditional demands for labour, we exploit the variations of real minimum wage across manufacturing subsectors to present evidence that this variable affects formal employment. The long-term elasticity of labour demand to the minimum wage is around –0.7. Accordingly, increases in the minimum wage lead to job losses for unskilled labour, mainly in plants with fewer than 100; thus, small increases in the minimum wage are desirable to protect employment. Labour demand is highly cyclical: the output elasticity is about 1.7. Thus, some flexibility in labour contracts is desirable to reduce the link between employment and variation of plants’ sales. Open-ended labour contracts might allow reductions of the nominal wage rather than inducing job losses during periods of severe slumps, as has happened during the COVID-19 pandemic.     

Evolution of recent economic-demographic modeling: A synthesis

This paper develops a flexible framework for modeling population's role in economic growth by assessing and extending a rendering suggested by several Harvard economists. Our framework includes a ``productivity' model explaining output-per-worker growth and a ``translation' model translating that growth into per-capita terms. We specify a core economic model and several ``enriched' demographic variants that include dependency, size, and density. Regressions using a cross-country panel spanning the period 1960-1995 reveal that combined impacts of demographic change have accounted for approximately 20% of per capita output growth impacts, with larger shares in Asia and Europe. An earlier draft of this paper was presented at a conference on ``Population Change, Labor Market Transition and Economic Development in Asia,' Institute of Economics, Academia Sinica, Taipei, Taiwan, 6–9 December 2002. A pre-publication version of this paper will be presented at a joint conference (by COE/JEPA) entitled ``Towards a new economic paradigm: Declining population growth, labor market transition and economic development under globalization,' held at the Awaji Yumebutai International Conference Center, Kobe, Japan, 17–19 December 2005. We have benefited from comments by Michelle Connolly, Andrew Mason, Pietro Peretto, Warren Sanderson, Alessandro Tarozzi, Jeffrey Williamson, and two anonymous referees.

数字化高灵敏度荧光显微镜在As_2O_3诱导MGC-803细胞核凋亡产生钙振荡研究中的应用

利用数字化高灵敏度荧光显微镜对As2O3诱导MGC-803细胞核凋亡过程中的钙振荡进行研究,通过图像中荧光强度随时间变化的规律反应钙振荡的频率和强度变化。结果证实As2O3诱导MGC-803细胞核凋亡过程中,的确引发了钙振荡,说明核钙参与了凋亡过程,并且钙振荡的频率以低频为主。对两相邻细胞核的钙振荡信号观察分析发现,两核钙强度变化曲线低频部分异常相似,几乎在同一时刻达到最高点和最低点。尽管钙波动的幅度不同,但基本频率相同,由此可初步预测钙信号以频率变化为表达特征。两细胞核凋亡呈同步化趋势,证明在受到As2O3刺激后,细胞核的凋亡不是个别现象。     

论《地之国》的创伤写作

约瑟夫·奥尼尔的《地之国》是近年来最出色的“后9.11”文学作品之一。小说表现了“9.11”事件给美国普通民众，尤其是纽约人造成的形形色色的个人心理创伤。奥尼尔在表现创伤的过程中，也探讨了应对和克服创伤的策略，并对美国政府在创伤形成中所扮演的角色进行了强烈的批判。

Taking time between g-string changes to educate ourselves: Sinéad O’Connor,Miley Cyrus,and celebrity feminism

This article examines the feminist response to a 2013 online “feud” between singers Miley Cyrus and Sinéad O’Connor that began when Cyrus connected the video for her single “Wrecking Ball” to O’Connor’s video for “Nothing Compares 2 U.” O’Connor’s response criticised Cyrus’ sexualised image, and the exchanges that followed sparked debate among feminists over the limits of sexual “agency,” and the sexual politics of feminism. This took place within a wider media context that has seen an apparent increase in female celebrities explicitly identifying themselves as feminist. Critics of this “celebrity feminism” argue that the sexualised star systems of its proponents are at odds with the aims of feminist politics. This article draws on post-structuralist feminist theory to question the positioning of celebrity feminism as exterior to an imagined “feminist movement.” Using the Cyrus/O’Connor feud, I argue that such a binary potentially reaffirms the structures of power that feminism seeks to oppose, and ignores the ways celebrity culture and contemporary media practice might combine to produce new understandings of the field of feminism.     

Decentralization and growth: Do informal institutions and rule of law matter?

We develop a model of the interactions among decentralization, informal institutions and the rule of law. The model sheds light on the ambiguous empirical results reported in the literature regarding the growth effects of the policy of devolving fiscal responsibility to local governments. We find that the distribution of civicness within a country determines the magnitude of the effects of decentralization on its regional convergence, as well as whether decentralization fosters or dampens the country’s national growth. We perform a series of simulated “reforms” using Monte Carlo methods parameterized using OECD countries data set. We then test our findings using a panel data set of 23 OECD countries covering the period 1975–2010. We find that the short and the long run growth effect of decentralization policy depends on the size of the policy reform and can range from extremely negative to positive depending on the rule of law, the level of social capital and its regional dispersion, in line with the model predictions.
