Evolution of Soils on Quaternary Reef Terraces of Barbados, West Indies

Abstract Soils on uplifted Quaternary reef terraces of Barbados, ∼125,000 to ∼700,000 yr old, form a climo-chronosequence and show changes in physical, chemical, and mineralogical properties with terrace age. Parent materials are dust derived from the Sahara, volcanic ash from the Lesser Antilles island arc, and detrital carbonate from the underlying reef limestone. Although some terrace soils are probably eroded, soils or their remnants are redder and more clay-rich with increasing terrace age. Profile-average Al2O3 and Fe2O3 content increases with terrace age, which partially reflects the increasing clay content, but dithionite-extractable Fe also increases with terrace age. Profile-average K2O/TiO2, Na2O/TiO2, and P2O5/TiO2 values decrease with terrace age, reflecting the depletion of primary minerals. Average SiO2/Al2O3 values also decrease with terrace age and reflect not only loss of primary minerals but also evolution of secondary clay minerals. Although they are not present in any of the parent materials, the youngest terrace soils are dominated by smectite and interstratified kaolinite-smectite, which gradually alter to relatively pure kaolinite over ∼700,000 yr. Comparisons with other tropical islands, where precipitation is higher and rates of dust fall may be lower, show that Barbados soils are less weathered than soils of comparable age. It is concluded that many soil properties in tropical regions can be potentially useful relative-age indicators in Quaternary stratigraphic studies, even when soils are eroded or changes in soil morphology are not dramatic.
Caveolins as tumour markers in lung cancer detected by combined use of cDNA and tissue microarrays

To identify new potential diagnostic markers for lung cancer, the expression profiles of 37 lung tumours were analysed using cDNA arrays. Seven samples were from small‐cell lung cancer (SCLC), two from large‐cell neuroendocrine tumours (LCNEC), and 28 from other non‐small‐cell lung cancers (mainly squamous cell cancer and adenocarcinoma). Principal component analysis and the permutation test were used to detect differences in the gene expression profiles and a set of genes was found that distinguished high‐grade neuroendocrine carcinomas (SCLC and LCNEC) from other lung cancers. In addition, several genes, such as caveolin‐1 (CAV1) and caveolin‐2 (CAV2), were constantly deregulated in all types of tumour sample, compared with normal tissue. The expression of these two genes was investigated further at the protein level on a tissue microarray containing tumours from 161 patients and normal tissues. Immunostaining for CAV1 was negative in 48% of tumours, whereas 28% of the tumours did not express CAV2. Lack of CAV1 protein expression was not caused by methylation or mutation. In stage I adenocarcinomas, CAV2 protein expression correlated with shorter survival. In conclusion, the present study was able to identify genes that have not previously been implicated in lung cancer by the combined use of two different array techniques. Some of these genes may provide novel diagnostic markers for lung cancer. Copyright © 2004 Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.
A simple approach to fabrication of high-quality HfSiON gate dielectrics with improved nMOSFET performances

A simple technique to form high-quality hafnium silicon oxynitride (HfSiON) by rapid thermal processing oxidation of physical vapor deposition hafnium nitride (HfN) thin films on ultrathin silicon oxide (SiO/sub 2/) or silicon oxynitride (SiON) layer is presented. Metal TaN gate electrode is also introduced into such HfSiON stacks. Excellent performances including large electron mobility (85%SiO/sub 2/at0.2 MV/cm), low leakage current (10/sup -4/ of SiO/sub 2/), and superior time-dependant dielectric breakdown reliability are achieved in HfSiON/SiO/sub 2/ stacks, and these results suggest such stacks are very promising for the low-power SOC applications in the near future. In addition, the improvement of the electron mobility in this HfSiON/SiO/sub 2/ stack by a reduction of the border traps in the HfSiON dielectric is demonstrated.
Adequacy Approach in School Finance

In many parts of the world, the focus of school financing has been on fiscal equity. However, school finance in the United States has been repositioning itself to provide for fiscal adequacy as well as improving equity since the 1990s. This article reviews adequacy in school finance, both from the conceptual and methodological perspective. Conceptually, adequacy is framed around the notions of adequacy of educational inputs, adequacy in school processes, and adequacy of educational outputs. From empirical perspective, four different methods are applied to quantify adequacy. Policy makers in developing countries should shift to fiscal adequacy which emphasizes on adequate per student funding for schools to deploy successful educational strategies in educating students to high performance standards.
The Molecular Evolution and Structural Organization of Self-Splicing Group I Introns at Position 516 in Nuclear SSU rDNA of Myxomycetes

Abstract Group I introns are relatively common within nuclear ribosomal DNA of eukaryotic microorganisms, especially in myxomycetes. Introns at position S516 in the small subunit ribosomal RNA gene are particularly common, but have a sporadic occurrence in myxomycetes. Fuligo septica, Badhamia gracilis, and Physarum flavicomum, all members of the family Physaraceae, contain related group IC1 introns at this site. The F. septica intron was studied at the molecular level and found to self-splice as naked RNA and to generate full-length intron RNA circles during incubation. Group I introns at position S516 appear to have a particularly widespread distribution among protists and fungi. Secondary structural analysis of more than 140 S516 group I introns available in the database revealed five different types of organization, including IC1 introns with and without His-Cys homing endonuclease genes, complex twin-ribozyme introns, IE introns, and degenerate group I-like introns. Both intron structural and phylogenetic analyses indicate a multiple origin of the S516 introns during evolution. The myxomycete introns are related to S516 introns in the more distantly related brown algae and Acanthamoeba species. Possible mechanisms of intron transfer both at the RNA- and DNA-levels are discussed in order to explain the observed widespread, but scattered, phylogenetic distribution.
The impact of immigration on the wage structure: Spain 1995-2002

In this paper we estimate the impact of inward migration flows on the Spanish wage structure over the period 1995-2002 by constructing counterfactual wage distributions that provide the wages that would have been observed had individual and job characteristics remain constant over time. Hence, we compute the impact of immigration on the wage distribution from (i) the estimated wage gaps between similar immigrants and native workers and (ii) the changes in the composition of employment associated to the arrival of new immigrants. Overall, we find that (i) the effects of immigration on wage changes are small and only noticeable when job characteristics are included as determinants of wages, and (ii) the correlation between the incidence of immigration in each decile of the wage distribution and the change in native wages not explained by changes in their individual and job characteristics is positive. These results suggest that other factors, besides immigration, should be identified as the key determinants of the wage moderation observed since the early nineties in Spain.
A Longitudinal Study of the Readability of the Chairman's Narratives in the Corporate Reports of a UK Company

Abstract This paper outlines an investigation of the readability of the chairman's narratives, as determined by the Flesch score, of a limited company's corporate reports from 1952–1985. It supports earlier studies which demonstrated that corporate reports were difficult to read, and had become more difficult to read over time. Turnover and readability were significantly negatively correlated. There also seemed to be a decrease in readability associated with the firm becoming a public limited company.
WAVESHRINK WITH FIRM SHRINKAGE

Donoho and Johnstone's (1994) WaveShrink procedure has proven valu- able for signal de-noising and non-parametric regression. WaveShrink has very broad asymptotic near-optimality properties. In this paper, we introduce a new shrinkage scheme, firm, which generalizes the hard and soft shrinkage proposed by Donoho and Johnstone (1994). We derive minimax thresholds and provide for- mulas for computing the pointwise variance, bias, and risk for WaveShrink with firm shrinkage. We study the properties of the shrinkage functions, and demon- strate that firm shrinkage offers advantages over both hard shrinkage (uniformly smaller risk and less sensitivity to small perturbations in the data) and soft shrink- age (smaller bias and overall L2 risk). Software is provided to reproduce all results in this paper.
Dividend policy issues in regulated and unregulated firms: a managerial perspective

Outlines previous research on four explanations for and various factors influencing dividend policy; and reports a survey of senior managers in US listed companies to determine their views. Finds strong support for the signalling explanation and some support for the bird‐in‐hand, tax‐preference and agency costs explanations, especially from regulated companies. Ranks the perceived importance of 20 factors influencing policy and discusses the top five (future earnings, past dividends, share price, concern over false signals and cash flow); and the differences between regulated and unregulated companies. Compares the rankings with Farrelly, Baker and Edelman (1986), recognizes the limitations of the study and considers consistency with other research.
When do corporate social responsibility initiatives impact on customer-facing employees? Evidence from India and the Netherlands

The vast majority of the extant literature on corporate social responsibility (CSR) has focused on the macro (firm) level of analysis by examining the linkage between CSR and firm-level outcomes. As such, very few studies have focused on the micro (individual) level of analysis. Against this backdrop, the present study focuses on the individual level of analysis thereby contributing to the emerging psychology of CSR literature, which considers employees' perceptions of their employing organizations' social actions as more important than organizations' objective CSR performance (Rupp, Shao, Thornton and Skarlicki (2013), ‘Applicants’ and Employees’ Reactions to Corporate Social Responsibility: The Moderating Effects of First-Party Justice Perceptions and Moral Identity,’ Personnel Psychology, 66, 895–933). Moreover, the study is one of the first examining the role of context in employee attitudes toward CSR. In particular, it builds on the psychology of CSR (e.g. Rupp et al. 2013) literature to propose a research framework that delineates the moderating effects of satisfaction with payment, satisfaction with the job itself and individualism in the relationship between corporate social performance (CSP) perceptions and customer-facing employees' behavioral outcomes. Data are collected from customer-facing employees in two major organizations in the Netherlands and India. Results suggest a complex interplay between CSP perceptions and the two facets of job satisfaction, and that national context is likely to moderate the contingent effects of CSP perceptions on customer-facing employees' behavioral outcomes.
How warm is the corporate responses to climate change? Evidence from Pakistan and the UK

In response to growing consensus among scientists and governments to act fast to avoid dangerous impacts of climate change, many industries have started to prepare for a carbon-constrained world. However, this response is far from being uniform. Often action is predicated on economic, technological, organizational and institutional drivers and barriers, which vary between countries and across industrial sectors. In order to understand the effectiveness of industry response, it is therefore important to analyse corporate response across different sectors in different countries. Focusing on the nine most energy-intensive and greenhouse gas (GHG) emitting industrial sectors, this paper compares corporate responses to climate change in Pakistan and the UK. By analysing the divergence of strategies adopted by industries across different sectors in two countries, the paper examines the key factors influencing corporate adoption and implementation of GHG reduction and energy-efficiency strategies in Pakistan and the UK.

Sleep bruxism is associated to micro‐arousals and an increase in cardiac sympathetic activity

Sleep bruxism (SB) subjects show a higher incidence of rhythmic masticatory muscle activity (RMMA) than control subjects. RMMA is associated with sleep micro‐arousals. This study aims to: (i) assess RMMA/SB episodes in relation to sleep cycles; (ii) establish if RMMA/SB and micro‐arousals occur in relation to the slow wave activity (SWA) dynamics; (iii) analyze the association between RMMA/SB and autonomic cardiac activity across sleep cycles. Two nights of polygraphic recordings were made in three study groups (20 subjects each): moderate to high SB, low SB and control. RMMA episodes were considered to occur in clusters when several groups of RMMA or non‐specific oromotor episodes were separated by less than 100 s. Correlations between sleep, RMMA/SB index and heart rate variability variables were assessed for the first four sleep cycles of each study group. Statistical analyses were done with SYSTAT and SPSS. It was observed that 75.8% of all RMMA/SB episodes occurred in clusters. Micro‐arousal and SB indexes were highest during sleep cycles 2 and 3 (P < 0.001). Within each cycle, micro‐arousal and RMMA/SB indexes showed an increase before each REM sleep (P ≤ 0.02). The cross‐correlation plot for micro‐arousal index showed positive association from 4 min preceding SB onset in the moderate to high SB subjects (P ≤ 0.06). The cross‐correlation plot revealed that SWA decreases following SB onset (P ≤ 0.05). Further cross‐correlation analysis revealed that a shift in sympatho‐vagal balance towards increased sympathetic activity started 8 min preceding SB onset (P ≤ 0.03). In moderate to severe SB subjects, a clear increase in sympathetic activity precedes SB onset.
Call centres, quality of work life and HRM practices

Purpose – The paper seeks to determine whether and how the quality of working life (QWL) varies between call centres (CCs) in the in‐house/outsourced, public and private sectors and the implications of these findings on human resource management (HRM). Design/methodology/approach – This paper reports on findings derived through empirical qualitative case study research in two Australian CCs: Govtcall, an in‐house, public‐sector CC, and Salesplus, an outsourced, private‐sector CC. Quality of work life outcomes are determined through in‐depth interviews with CSOs, supervisors and managers, where a comparative approach is utilised.Findings – The in‐house, public‐sector CC Govtcall emerges as being inferior in terms of job content, working hours and managerial/supervisory style and strategies. Conversely, Salesplus features a management model that is more akin to what would be expected in a CC operating under a professional service model.Research limitations/implications – The sample size was limited to two CC.
International tourism networks

Much of tourism development is predicated on the successful working of organisations alignment in the form of partnerships or “networks”. However, tourism networks have been relatively neglected as an area of academic study. This paper presents findings of research focusing on international tourism networks and draws out learning points from the examination of relatively successful examples. A review of relevant literature considers the definition and description of networks, their benefits, and identifiable success factors, and the research methodology applied is described. Discussion follows as to the main functions and benefits of tourism networks in relation to learning and exchange, business activity, and community. Key issues that emerge include: structure and leadership, resourcing, engagement of participants, inter‐organisational learning, and sustainability. The paper concludes by identifying significant success factors and consequential management implications with specific references to tourism destinations as learning communities.
Antioxidant activity of eugenol and related monomeric and dimeric compounds.

Since the inhibitory effect of eugenol (a), which was isolated as an antioxidative component from plant, Caryopylli flos, on lipid peroxidation was less than that of alpha-tocopherol, we synthesized the eugenol-related compounds dieugenol (b), tetrahydrodieugenol (c), and dihydroeugenol (d), to find new strong antioxidants and assessed them for their inhibitory effect on lipid peroxidation and scavenging ability for superoxide and hydroxyl radicals. The antioxidative activities were in the order: (b)>(c)>(d)>(a) for the thiobarbituric acid reactive substance (TBARS) formation. These results suggest that the dimerized compounds have higher antioxidant activities than that of the monomers. Electron spin resonance (ESR) spin trapping experiments revealed that eugenol and its dimer, having allyl groups in the structure, scavenged superoxide, and that only eugenol trapped hydroxyl radicals under the conditions used. These finding suggest that eugenol and dieugenol have a different mechanism of antioxidation, i.e. eugenol may inhibit lipid peroxidation at the level of initiation, however, the related dimeric compounds may inhibit lipid peroxidation at the level of propagation of free radical chain reaction like alpha-tocopherol.
Bed rest following embryo transfer might negatively affect the outcome of IVF/ICSI: a systematic review and meta-analysis

Abstract The majority of patients undergoing in vitro fertilization (IVF) and intracytoplasmatic sperm injection (ICSI) treatment will reach the stage of embryo transfer (ET), but only a small proportion of transferred embryos implant. Bed rest following ET has been recommended as a way to prevent embryo expulsion by gravity. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) published prior to May 2014 reporting the effect of bed rest following ET, and irrespective of language, country of origin, blinding or sample size. Four RCTs, including 757 women met the inclusion criteria. Bed rest following ET did not improve clinical pregnancy and live birth rates, but reduced the implantation rate. The quality of the trials included was moderate because of attrition bias and possible reporting bias. The findings of this systematic review and meta-analysis are concordant with previously published literature and suggest that bed rest is not beneficial following ET. Moreover, it might negatively affect the outcome of IVF/ICSI cycles via stress/anxiety mechanisms.
Survey of Haircoat Fungal Flora for the Presence of Dermatophytes in a Population of White-tailed Deer (Odocoileus virginianus) in Virginia

Before releasing rehabilitated wildlife, patients should be cured of all infectious agents that pose a risk to free-roaming wildlife or humans after release. Dermatophyte fungi, commonly known as “ringworm,” have zoonotic potential and may be carried as normal flora on the haircoats of certain species. Outbreaks of ringworm are anecdotally reported to occur in white-tailed deer (Odocoileus virginianus) fawns, but no prevalence surveys have been conducted on the haircoat flora of free-roaming individuals. In November 2008, we tested 60 legally hunted white-tailed deer for dermatophyte flora by using a modified MacKenzie technique. Results indicate it is unlikely that wild, mature white-tailed deer in Virginia, USA, carry dermatophyte fungi as normal haircoat flora. Therefore, wildlife rehabilitators and hunters are at low risk for dermatophyte infection by direct contact with this species. In addition, the RapidVet-D 3 Day Test for Veterinary Dermatophytosis was determined to have poor specificity for presence of dermatophyte fungi on asymptomatic white-tailed deer in Virginia.
Initiation rites at menarche and self-reported dysmenorrhoea among indigenous women of the Colombian Amazon: a cross-sectional study

Objectives To investigate the association between self-reported dysmenorrhoea and patterns of female initiation rites at menarche among Amazonian indigenous peoples of Vaupés in Colombia. Design A cross-sectional study of all women in seven indigenous communities. Questionnaire administered in local language documented female initiation rites and experience of dysmenorrhoea. Analysis examined 10 initiation components separately, then together, comparing women who underwent all rites, some rites and no rites. Settings Seven indigenous communities belonging to the Tukano language group in the Great Eastern Reservation of Vaupés (Colombia) in 2008. Participants All women over the age of 13 years living in the seven communities in Vaupés, who had experienced at least two menstruations (n=185), aged 13–88 years (mean 32.5; SD 15.6). Primary and secondary outcome measures The analysis rested on pelvic pain to define dysmenorrhoea as the main outcome. Women were also asked about other disorders present during menstruation or the precedent days, and about the interval between two menstruations and duration of each one. Results Only 17.3% (32/185) completed all initiation rites and 52.4% (97/185) reported dysmenorrhoea. Women not completing the rites were more likely to report dysmenorrhoea than those who did so (p=0.01 Fisher exact), taking into account age, education, community, parity and use of family planning. Women who completed less than the full complement of rites had higher risk than those who completed all rites. Those who did not complete all rites reported increased severity of dysmenorrhoea (p=0.00014). Conclusions Our results are compatible with an association between traditional practices and women's health. We could exclude indirect associations with age, education, parity and use of family planning as explanations for the association. The study indicates feasibility, possible utility and limits of intercultural epidemiology in small groups.
Carcinoma of the stomach in atomic bomb survivors. A comparison of clinicopathologic features to the general population

The results of surgical treatment of gastric cancer were reviewed retrospectively for 135 atomic bomb survivors and 377 control patients. The mean age was significantly higher in the survivors than in the controls. Otherwise, both groups were quite comparative especially in terms of the stage of the disease. Histopathologically, the rates of poorly differentiated or undifferentiated types of carcinoma and secondary lymph node involvements were significantly lower in the survivors than in the controls. There were no significant difference between the two groups in postoperative morbidity and mortality rates and long‐term survival rate. The incidence of second primary malignancies, however, was apparently higher in the survivors than in the controls.
