Bloody Sunday is almost universally recognised as ‘unjustified and unjustifiable’. But lessons must be drawn for peace in Northern Ireland, and for counterinsurgency more generally

Jim Hughes writes that the events of Bloody Sunday and the ‘shock’ of concentrated violence in the early phase of the Northern Ireland conflict reverberated and shaped the conflict for the following decades. However, the violence also led to the start of a process that would result in the Good Friday Agreement

Comparison of Varying Tissue Freezing Methods on Murine Colonic Tissue

Histology often requires a tissue specimen to be embedded so that it may be sectioned, stained, and mounted on a microscope slide for viewing. One common method of tissue embedding for rapid histology is freezing, since freezing allows tissue to be stored without the need for fixing. Frozen tissue is often embedded in a medium such as Optimal Cutting Temperature (OCT) compound so that it can be sectioned using a cryostat. However, factors such as ice-crystal formation during the freezing process can cause damage to the tissue. As such, the protocol used to freeze the tissue can affect the quality of the slides. The purpose of this project is to compare different freezing methods and examine their strengths and weaknesses when applied to murine colonic tissue. Murine colonic tissue was frozen using two snap-freezing methods, piezoelectric freezing, and two different cold storage methods, each with their own three to four variations. Transverse sections were made in a cryostat, which were mounted on slides and stained using a hematoxylin and eosin (H&E) staining protocol. The sections were then imaged using a light microscope. A blind test was conducted to rate the image quality and inter-rater agreement was calculated using Fleiss’s Kappa. Paraffin embedding obtained the highest score, while OCT embedding inside a -80°C freezer received the second highest score

'Exit' in deeply divided societies: regimes of discrimination in Estonia and Latvia and the potential for Russophone migration.

Hirschman’s model of ‘exit’ envisages that mass migration can communicate feedback to a state and elicit modifying policy behaviour. The regimes of discrimination against Russophones in Estonia and Latvia are examined to demonstrate that in certain conditions of inter-ethnic conflict the model does not work as predicted. In deeply divided societies the mass migration of a minority can be intentionally promoted by a majority regime of discrimination and thus does not perform a feedback function. Equally, in such conditions migration may operate as a safety valve to release the build up of minority antagonisms against the discriminatory regimes. The cases of Estonia and Latvia also illustrate the limitations of international conditionality from the EU and OSCE to prevent anti-minority policies, when there is a lack of international commitment and when governing elites resist. Given the lack of political will in Estonia and Latvia to modify the regimes of discrimination, and the poor prospects for integration or assimilation, the article predicts a significant out-migration by Russophones to other EU member states when restrictions on freedom of movement are eased after the transitional period.

Length-Based Attacks for Certain Group Based Encryption Rewriting Systems

In this note, we describe a probabilistic attack on public key cryptosystems based on the word/conjugacy problems for finitely presented groups of the type proposed recently by Anshel, Anshel and Goldfeld. In such a scheme, one makes use of the property that in the given group the word problem has a polynomial time solution, while the conjugacy problem has no known polynomial solution. An example is the braid group from topology in which the word problem is solvable in polynomial time while the only known solutions to the conjugacy problem are exponential. The attack in this paper is based on having a canonical representative of each string relative to which a length function may be computed. Hence the term length attack. Such canonical representatives are known to exist for the braid group

A U.S. Manager\u27s Guide to Differences Between IFRS and U.S. GAAP

International Financial Reporting Standards (IFRS) are now required for consolidated financial reports for all European Union exchange-listed companies. Officials estimated that for 2005, the initial year of EU adoption, 8,000 financial statements were prepared in accordance with IFRS for the first time. Other countries have also adopted IFRS or IFRS-equivalent financial reporting standards. IFRS differ from U.S. Generally Accepted Accounting Principles (GAAP) in many key areas. The International Accounting Standards Board (IASB) and the Financial Accounting Standards Board (FASB) are working on various convergence projects designed to reduce or eliminate differences between the two sets of reporting standards. But existing differences will likely continue for at least the next two years, and, for many accounting topics, differences are likely to last much longer. This article highlights the 20 convergence projects and summarizes the differences between the two sets of standards. In addition, differences in three topics that are not included in the convergence efforts are identified. Differences between IFRS and U.S. GAAP found in actual EU company Form 20-F filings are used to illustrate the impact of the reporting-standard differences

The Effects of Market Liberalization on the Relative Earnings of Chinese Women

In this paper we first explore the effects of differences in labor market institutions and the degree of market liberalization on the size and composition of gender wages gaps in China's urban labor markets. We use enterprise-ownership type, enterprise age, and workers' methods of finding employment as proxies for the extent of market liberalization. We find both the size of the wage gaps and the proportion of the gap left unexplained by differences in productive characteristics largest in the most liberalized (joint venture) sector, and smallest in the least liberalized (state) sector. We next investigate the effects of differences in wage structure on the gender wage gaps. We find that differences in wage structure, in general, and the degree of wage dispersion, in particular, are extremely important in accounting for the larger wage gaps in the joint venture and collective sectors relative to the state-owned sector.http://deepblue.lib.umich.edu/bitstream/2027.42/39844/3/wp460.pd

The Emerging Wealth Belt: New Jersey's New Millenium Geography

Describes the emergence of an economic cluster of counties in New Jersey and explains the reason for this new spatial alignment of the economy. The report also traces the historical shifts in the economic geography of New Jersey from its rural beginnings to its high technology present. Finally, the report describes the countervailing deomgraphy and economic intiatives that once more may tilt growth back to urban New Jersey. It notes, however, that a variety of economic and public policy challenges raise serious questions about the outcome of the redirection of our state's spatial development
