Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.

Nicotinic acetylcholine receptors (nAChRs) are ligand‐gated ion channels that bring about a diversity of fast synaptic actions. Analysis of the Caenorhabditis elegans genome has revealed one of the most‐extensive and diverse nAChR gene families known, consisting of at least 27 subunits. Striking variation with possible functional implications has been observed in normally conserved motifs at the acetylcholine‐binding site and in the channel‐lining region. Some nAChR subunits are particular to neurons whilst others are present in both neurons and muscles. The localization (...) of subunits in non‐synaptic regions suggests novel roles for nAChRs. Genetic and heterologous expression studies have identified a subset of nAChR subunits that are important drug targets while the study of mutants has identified genes functionally‐linked to nAChRs. Future studies using C. elegans offer the prospect of increasing our understanding of the functional diversity of a complex nAChR gene family as well as addressing the role of nAChRs and associated proteins in human disorders.

Amyotrophic lateral sclerosis (ALS) is a progressive degenerative disorder of motor neurones. Although the genetic basis of familial forms of ALS has been well explored, the molecular basis of sporadic ALS is less well understood. Recent evidence has linked sporadic ALS with the failure to edit key residues in ionotropic glutamate receptors, resulting in excessive influx of calcium ions into motor neurones which in turn triggers cell death. Here we suggest that edited AMPA glutamate (GluR2) receptor subunits serve as gatekeepers (...) for motor neurone survival. BioEssays 30:1185–1192, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

We show that if κ is a weakly compact cardinal, then $\left( \matrix \kappa ^{+} \\ \kappa\endmatrix \right)\rightarrow \left(\left( \matrix \alpha \\ \kappa \endmatrix \right)_{m}\left( \matrix \kappa ^{n} \\ \kappa \endmatrix \right)_{\mu}\right)^{1,1}$ for any ordinals α < κ⁺ and µ < κ, and any finite ordinals m and n. This polarized partition relation represents the statement that for any partition $\kappa \times \kappa ^{+}=\underset i<m\to{\bigcup }K_{i}\cup \underset j<\mu \to{\bigcup }L_{j}$ of κ × κ⁺ into m + µ pieces either there (...) are A ∈ [κ]κ, B ∈ [κ⁺]α, and i < m with A × B ⊆ Ki or there are C ∈ [κ]κ, D ∈ [κ⁺]α, and j < μ with C × D ⊆ Lj. Related results for measurable and almost measurable κ are also investigated. Our proofs of these relations involve the use of elementary substructures of set models of large fragments of ZFC.

Conducting research in a prison setting is ethically challenging. Because history is full of unethical research conducted in prison settings, researchers are often afraid of doing research in this area. It is argued that too much emphasis has been put on the protection of prison inmates as a vulnerable population. Consequently, too little research is being conducted where the focus is on those factors which serve to make the prison population vulnerable. In this paper ethical questions, emerging when conducting a (...) study on literacy and mental health among Norwegian prison inmates, are presented and discussed. Relevant questions relate to topics which include ethical clearance of the research protocol, the consent procedure, clarification of roles and the publication of the results. The ethical questions are discussed in relation to the four principles of ‘respect for the client's rights and dignity’, ‘competence’, ‘responsibility’ and ‘integrity’ set out in the meta-code of ethics, formulated by the European Federation of Professional Psychologists Associations. The wider relationships between ethics in society, research ethics in general, and ethics when conducting research in a prison setting are also considered. (shrink)

This paper addresses the changing ideology regarding reproduction, an evolving American, and potentially worldwide, value system regarding children and parenthood. Children are increasingly being seen as products, and the new technology of reproduction, including the sale of reproductive material and services and especially prenatal diagnosis and selective abortion, encourage this commodification of the fetus. While the new technology does indeed offer new choices, it also creates new structures and new limitations on choice. In the contemporary American social structure, these choices (...) are inevitably couched in terms of production and commodification, and thus do not offer individuals genuine choice or control.

Study of Nyāyasiddhāntadīpa of Śaśadhara, treatise on Nyaya philosophy; includes Sanskrit text with English translation.

This study provides current data on key questions about retraction of scientific articles. Findings confirm that the rate of retractions remains low but is increasing. The most commonly cited reason for retraction was research error or inability to reproduce results; the rate from research misconduct is an underestimate, since some retractions necessitated by research misconduct were reported as being due to inability to reproduce. Retraction by parties other than authors is increasing, especially for research misconduct. Although retractions are on average (...) occurring sooner after publication than in the past, citation analysis shows that they are not being recognised by subsequent users of the work. Findings suggest that editors and institutional officials are taking more responsibility for correcting the scientific record but that reasons published in the retraction notice are not always reliable. More aggressive means of notification to the scientific community appear to be necessary. (shrink)

Study of Nyāyasiddhāntadīpa of Śaśadhara, treatise on Nyaya philosophy; includes Sanskrit text with English translation.

Study with reference to Tattvacintāmaṇi of Gaṅgeśa, 13th cent.

Contributed articles presented at the International Seminar on Ultimate Reality and Meaning during July 2006 at Centre of Advanced Study in Sanskrit, University of Pune.

These essays were originally presented at the first of an annual series of seminars in the humanities at John Hopkins. To avoid imposing an artificial unity on the subject, the contributors were deliberately left unguided in their choice of subject and method. The result of this policy is a rich and stimulating collection ranging from gardens to musicology. Reproductions of paintings and copious printings of musical scores show that no expense was spared to make the book as useful as possible. (...) Of greatest interest to philosophers are George Boas's witty demolition of "the age of reason" as a description for the period, J. A. Passmore on "the malleability of man," Isaiah Berlin's long reconsideration of Herder, Alfred Cobban on "the Enlightenment and the French Revolution," and Henry Guerlac on Newton's place in intellectual history.—W.
