Researchers in different parts of the southwestern United States continue to debate whether the end of the Basketmaker period coincides with a general shift from supplemental to intensive maize agriculture across the U.S. Southwest. In some areas this transition appears to have occurred earlier, with heavy reliance on agriculture appearing by the Basketmaker II period. In this study, evidence from dental caries in southwestern Colorado populations supports the latter view, suggesting that Basketmaker subsistence in this area included a heavy reliance on agricultural products. Dental caries frequencies in both Basketmaker and post-Basketmaker samples are well within the expected range for full-time agriculturalists. Although there is no significant association between time period and caries rate, frequencies of interproximal caries and numbers of carious teeth per individual may indicate maize-processing differences between samples obtained from the two temporal periods. Differences in the intensity of maize production, rather than consumption, may contribute to the current lack of agreement on the timing of Southwestern agricultural dependence.

Abstract. The concept of emotional intelligence (EI) has attracted growing interest from researchers working in various fields. The present study examined the long-term stability (32 months) of EI-related abilities over the course of a major life transition (the transition from high school to university). During the first week of full-time study, a large group of undergraduates completed the EQ-i:Short; 32 months later a random subset of these students (N = 238), who had started their postsecondary education within 24 months of graduating from high school, completed the measures for a second time. The study found EI scores to be relatively stable over the 32-month time period. EI scores were also found to be significantly higher at Time 2; the overall pattern of change in EI-levels was more than can be attributed to the increased age of the participants.

Abstract Poleward migration of the latitudinal edge of the tropics of 0.25°–3.0° decade−1 has been reported in several recent studies based on satellite and radiosonde data and reanalysis output covering the past ~30 yr. The goal of this paper is to identify the extent to which this large range of trends can be explained by the use of different data sources, time periods, and edge definitions, as well as how the widening varies as a function of hemisphere and season. Toward this end, a suite of tropical edge latitude diagnostics based on tropopause height, winds, precipitation–evaporation, and outgoing longwave radiation (OLR) are analyzed using several reanalyses and satellite datasets. These diagnostics include both previously used definitions and new definitions designed for more robust detection. The wide range of widening trends is shown to be primarily due to the use of different datasets and edge definitions and only secondarily due to varying start–end dates. This study also shows that the large trends (>~1° decade−1) previously reported in tropopause and OLR diagnostics are due to the use of subjective definitions based on absolute thresholds. Statistically significant Hadley cell expansion based on the mean meridional streamfunction of 1.0°–1.5° decade−1 is found in three of four reanalyses that cover the full time period (1979–2009), whereas other diagnostics yield trends of −0.5°–0.8° decade−1 that are mostly insignificant. There are indications of hemispheric and seasonal differences in the trends, but the differences are not statistically significant.

Aims and MethodA postal survey of consultants in liaison psychiatry was carried out in the spring of 2002 to document the current state of liaison psychiatry in the UK and the Republic of Ireland. Information was collected on post specifications, clinical organisation and plans for further local development.ResultsNinety-three liaison consultants were identified. Seventy-seven posts were full-time or half-time, compared with 43 such posts in 1996. During the same time period, specialist registrar training posts have doubled from 30 to 61. A third of respondents anticipated further consultant posts in their region.Clinical ImplicationsDespite the increase in the number of liaison consultants since 1996, the numbers still fall below that recommended by the Royal College of Psychiatrists. Liaison consultants need to improve links with primary care and continue to develop specialised services to demonstrate the qualitative and financial benefits that liaison psychiatry has to offer to a wide range of patients.

ABSTRACT There is a high prevalence of β-lactam- and macrolide-resistant Streptococcus pneumoniae in Taiwan. To understand the in vitro susceptibilities of recent isolates of S. pneumoniae to fluoroquinolones and telithromycin (which is not available in Taiwan), the MICs of 23 antimicrobial agents for 936 clinical isolates of S. pneumoniae isolated from different parts of Taiwan from 2000 to 2001 were determined by the agar dilution method. Overall, 72% of isolates were not susceptible to penicillin (with 61% being intermediate and 11% being resistant) and 92% were resistant to erythromycin. Telithromycin MICs were ≥1 μg/ml for 16% of the isolates, and for 99% of these isolates the MICs of all macrolides tested were ≥256 μg/ml; all of these isolates had the constitutive macrolide-lincosamide-streptogramin B phenotype. Eighty-eight percent of the isolates were resistant to three or more classes of drugs. The ciprofloxacin MICs were ≥4 μg/ml for six (0.6%) isolates from five patients collected in 2000 and 2001, and the levofloxacin MICs were ≥8 μg/ml for five of these isolates. Seven isolates for which ciprofloxacin MICs were ≥4 μg/ml, including one isolate recovered in 1999, belonged to three serotypes (serotype 19F, five isolates; serotype 23A, one isolate; and serotype 23B, one isolate). The isolates from the six patients for which ciprofloxacin MICs were ≥4 μg/ml had different pulsed-field gel electrophoresis profiles and random amplified polymorphic DNA patterns, indicating that no clonal dissemination occurred over this time period. Despite the increased rate of fluoroquinolone use, the proportion of pneumococcal isolates for which ciprofloxacin MICs were elevated (≥4 μg/ml) remained low. However, the occurrence of telithromycin resistance is impressive and raises concerns for the future.

Dental caries is among the most prevalent chronic diseases of childhood, affecting larger part of children and adults. Non-treated enamel caries can lead to destruction and then spreads into the underlying softer and sensitive dentine layer. Dental restorative materials are applied to treat and reconstruct damaged teeth clinically and recover their functions. Currently, there are various dental restorative materials available, and many appropriate materials are used to restore dental carious teeth. The applicability of biomimetic principles can elicit innovations in restorative dentistry for tooth conservation and preservation. There are three types of materials commonly used in dental restorations: resin, alloys, and ceramic. During the past decade, zirconia-based ceramics have been successfully introduced into the clinic due to acceptable biocompatibility, lower price compared with gold restorations, and better appearance than traditional metal-ceramic restorations. Recently, zirconia restoration is an acceptable treatment option in restorative dentistry and a developing trend in esthetic dentistry.

This study seeks to determine if term limits increase the likelihood of women being elected to legislative seats. Using a simple comparison of growth rates, we found that, during the initial period of term limit implementation (1991 to 2009), the increase of females elected to state legislatures with term limits was approximately the same as to those without term limits. Additionally, a comparison of the growth rate of females elected to the non-term-limited United States House of Representatives with those of the state legislatures during this same time period shows that the U.S. House actually had a greater increase than state legislatures both with and without term limits. Moreover, in California, which has a full-time, professional state legislature with electoral dynamics similar to the U.S. House, the proportion of women elected to the state’s non-term limited U.S. House delegation from 1990 to 2009 exceeded the proportion of women elected to its term-limited state legislature. These comparisons all suggest that term limits do not facilitate the election of female candidates to legislative seats.


Subject The outlook for agriculture. Significance At the beginning of his term, President Mauricio Macri eliminated export quotas and removed or reduced export taxes on agricultural products, which boosted grain and meat production and exports. However, a severe drought last summer prompted a significant fall in soya and maize production. Impacts Agriculture will remain an important source of foreign exchange. A new deal with China should boost beef exports, which may encourage farmers to increase falling herd numbers. Fiscal constraints risk limiting plans to expand irrigation projects.
