The Economic Partnership Agreements between the African, Caribbean and Pacific countries and the European Union should serve as an opportunity to accelerate ACP global and regional trade integration and as an important tool for development and the eradication of poverty. There are, however, a number of preconditions. This article argues that institutional quality plays a key role in successful trade liberalisation. In fact, only countries with high‐quality institutions, partly in the form of good government regulation, are likely to benefit from trade. Unfortunately, the vast majority of African countries have excessive regulation that hinders them from taking advantage of trade. The necessary reforms to resolve this problem pose significant challenges, implying major risks for these countries in the EPA process.  相似文献

ABSTRACT

In the aftermath of the Cambridge Analytica controversy, social media platform providers such as Facebook and Twitter have severely restricted access to platform data via their Application Programming Interfaces (APIs). This has had a particularly critical effect on the ability of social media researchers to investigate phenomena such as abuse, hate speech, trolling, and disinformation campaigns, and to hold the platforms to account for the role that their affordances and policies might play in facilitating such dysfunction. Alternative data access frameworks, such as Facebook’s partnership with the controversial Social Science One initiative, represent an insufficient replacement for fully functional APIs, and the platform providers’ actions in responding to the Cambridge Analytica scandal raise suspicions that they have instrumentalised it to actively frustrate critical, independent, public interest scrutiny by scholars. Building on a critical review of Facebook’s public statements through its own platforms and the mainstream media, and of the scholarly responses these have drawn, this article outlines the societal implications of the ‘APIcalypse’, and reviews potential options for scholars in responding to it.  相似文献

Optimal string alignment is used to discover evolutionary relationships or mutations in DNA/RNA or protein sequences. Errors, missing parts or uncertainty in such a sequence can be covered with wild cards, so-called wild bases. This makes an alignment possible even when the data are corrupted or incomplete. The extended pairwise local alignment of wild card DNA/RNA sequences requires additional calculations in the dynamic programming algorithm and necessitates a subsequent best- and worst-case analysis for the wild card positions. In this paper, we propose an algorithm which solves the problem of input data wild cards, offers a highly flexible set of parameters and displays a detailed alignment output and a compact representation of the mutated positions of the alignment. An implementation of the algorithm can be obtained at https://github.com/sysbio-bioinf/swat+ and http://sysbio.uni-ulm.de/?Software:Swat+.  相似文献

Economic and rational‐choice theories suggest that individuals form unions or have children because these decisions increase their subjective well‐being or “happiness.” We investigate this relation using within‐MZ (identical) twin pair estimates to control for unobserved factors, such as optimistic preferences, that may simultaneously affect happiness, partnerships, and fertility. Our findings, based on Danish twins aged 25–45 and 50–70 years old, include the following. (1) Currently being in a partnership has large positive effects on happiness. (2) A first child substantially increases well‐being, in analyses without controls for partnerships, and males enjoy an almost 75 percent larger happiness gain from a first‐born son than from a first‐born daughter; however, only females enjoy a happiness gain from the first‐born child with controls for partnerships. (3) Additional children beyond the first child have a negative effect on subjective well‐being for females, while there is no effect for males. (4) Ever having had children does not significantly affect the subjective well‐being of males or females aged 50–70 years.  相似文献

The paper examines the relationship between environmental policy and employment. It argues that environmental policy probably has a positive effect on employment. To support this conclusion the following arguments will be made: polluting companies, and hence employment in these companies, can be, but is not always, negatively affected by environmental policy; polluting companies do not move to another country due to environmental policy; the ecosector is an important employment sector; and, the net balance between job losses and gains due to environmental policy is positive. This conclusion is conditional on certain assumptions concerning the functioning of labour markets, the improvement in environmental quality and the normative implications of the debate.  相似文献
