No full textThe state of civic participation in the U.S. is the subject of much hand-wringing. The lament is generally that citizens are withdrawn - that civic life is less vibrant than it once was and should be. This book review welcomes Downsizing Democracy: How America Sidelined its Citizens and Privatized its Public, by Matthew Crenson & Benjamin Ginsburg (2002), as an alternative to the tendency to blame citizens for the current malaise. Crenson & Ginsburg make the case that the government itself has disinvited civic participation in several key ways. The author observes that, notwithstanding this lack of invitation, citizens can and should still take on themselves the responsibility for civic action - not just in traditional political spheres, but in the myriad venues of our everyday lives.525-2927

Dynamics of DNA replication loops reveal temporal control of lagging-strand synthesis
No full textIn all organisms, the protein machinery responsible for the replication of DNA, the replisome, is faced with a directionality problem. The antiparallel nature of duplex DNA permits the leading-strand polymerase to advance in a continuous fashion, but forces the lagging-strand polymerase to synthesize in the opposite direction. By extending RNA primers, the lagging-strand polymerase restarts at short intervals and produces Okazaki fragments. At least in prokaryotic systems, this directionality problem is solved by the formation of a loop in the lagging strand of the replication fork to reorient the lagging-strand DNA polymerase so that it advances in parallel with the leading-strand polymerase. The replication loop grows and shrinks during each cycle of Okazaki fragment synthesis. Here we use single-molecule techniques to visualize, in real time, the formation and release of replication loops by individual replisomes of bacteriophage T7 supporting coordinated DNA replication. Analysis of the distributions of loop sizes and lag times between loops reveals that initiation of primer synthesis and the completion of an Okazaki fragment each serve as a trigger for loop release. The presence of two triggers may represent a fail-safe mechanism ensuring the timely reset of the replisome after the synthesis of every Okazaki fragment.
Sex differences in Cognitive Abilities Test scores: a UK national picture
No full textBackground and aims. There is uncertainty about the extent or even existence of sex differences in the mean and variability of reasoning test scores ( Jensen, 1998; Lynn, 1994, ; Mackintosh, 1996). This paper analyses the Cognitive Abilities Test (CAT) scores of a large and representative sample of UK pupils to determine the extent of any sex differences.
Sample. A nationally representative UK sample of over 320,000 school pupils aged 11-12 years was assessed on the CAT (third edition) between September 2001 and August 2003. The CAT includes separate nationally standardized tests for verbal, quantitative, and non-verbal reasoning. The size and recency of the sample is unprecedented in research on this issue.
Methods. The sheer size of the sample ensures that any sex difference will achieve statistical significance. Therefore, effect sizes (d) and variance ratios (VR) are employed to evaluate the magnitude of sex differences in mean scores and in score variability, respectively.
Results. The mean verbal reasoning score for girls was 2.2 standard score points higher than the mean for boys, but only 0.3 standard points in favour of girls for non-verbal reasoning (NVR), and 0.7 points in favour of boys for quantitative reasoning (QR). However, for all three tests there were substantial sex differences in the standard deviation of scores, with greater variance among boys. Boys were over represented relative to girls at both the top and the bottom extremes for all tests, with the exception of the top 10% in verbal reasoning.
Conclusions. Given the small differences in means, explanations for sex differences in wider domains such examination attainment at age 16 need to look beyond conceptions of `ability'. Boys tend to be both the lowest and the highest performers in terms of their reasoning abilities, which warns against the danger of stereotyping boys as low achievers
Characteristics of oligonucleotide frequencies across genomes: Conservation versus variation, strand symmetry, and evolutionary implications
No full textOne of the objectives of evolutionary genomics is to reveal the genetic information contained in the primordial genome (called the primary genetic information in this paper, with the primordial genome defined here as the most primitive nucleic acid genome for earth’s life) by searching for primitive traits or relics remained in modern genomes. As the shorter a sequence is, the less probable it would be modified during genome evolution. For that reason, some characteristics of very short nucleotide sequences would have considerable chances to persist during billions of years of evolution. Consequently, conservation of certain genomic features of mononucleotides, dinucleotides, and higher-order oligonucleotides across various genomes may exist; some, if not all, of these features would be relics of the primary genetic information. Based on this assumption, we analyzed the pattern of frequencies of mononucleotides, dinucleotides, and higher-order oligonucleotides of the whole-genome sequences from 458 species (including archaea, bacteria, and eukaryotes). Also, we studied the phenomenon of strand symmetry in these genomes. The results show that the conservation of frequencies of some dinucleotides and higher-order oligonucleotides across genomes does exist, and that strand symmetry is a ubiquitous and explicit phenomenon that may contribute to frequency conservation. We propose a new hypothesis for the origin of strand symmetry and frequency conservation as well as for the constitution of early genomes. We conclude that the phenomena of strand symmetry and the pattern of frequency conservation would be original features of the primary genetic information
Oregon Law Review
No full textThe article begins by documenting deep inequality in the form of Black-White wealth disparities. While the overall wealth distribution in the United States is highly unequal from both historical and international perspectives, racial wealth disparities are particularly acute, with median Black net worth approximately a tenth of median White net worth (as compared to median Black income that is approximately two-thirds of median White income). Next, the article ties the perpetuation of this inequality to current inheritance law. It then confronts this inequality as a civil rights issue in terms of its social effects, its historical causes, and legal avenues for attacking it. Finally, the article proposes two changes in our laws of succession to address this contemporary manifestation of White advantage and Black disadvantage. First, the article explains how civil rights considerations support existing proposals that inheritances be taxed as windfall income to those who receive them (as are lottery winnings currently). Second, the article identifies a need for revising intestacy law to provide heirs with clear title to assets, especially homes belonging to families of modest wealth whose wealth is primarily the value of those homes.2453-5048
