Effect of pretreatment on a platinized tin oxide catalyst used for low-temperature CO-oxidation

A commercial platinized tin oxide catalyst used for low-temperature CO oxidation has been characterized using ion scattering spectroscopy (ISS), Auger electron spectroscopy (AES) and Electron Spectroscopy for Chemical Analysis (ESCA) before and after reduction in 40 Torr of CO for 1 hour at various temperatures from 75 to 175 C. The reduction results in loss of surface oxygen, formation of metallic tin, conversion of platinum oxides to Pt-O-Sn and Pt(OH)2 and a small amount of metallic Pt which alloys with the tin. These results should be useful in understanding how the pretreatment temperature affects the catalytic activity of platinized tin oxide toward CO oxidation

BIPOLAR II DISORDER AND BORDERLINE PERSONALITY DISORDER - CO-MORBIDITY OR SPECTRUM?

We assess the number of patients who we have on the Database of a Community Mental Health Team in the UK who have Bipolar Disorder and Borderline Personality Disorder. We report how many of these have been seen as having both disorders. Hence we discuss the issue as to whether Borderline Personality disorder is to be placed within the bipolar spectrum. We note the difficulties regarding the use of phenomenology alone to decide this problem, and we note the similarities in genetics, neuroimaging observations and neurobiological mechanisms among the following conditions; Bipolar Disorder, Unipolar Depression, Post-traumatic Stress Disorder, and Borderline Personality Disorder. Ethiologies such as Trauma, Abuse, Childhood adversity and exposure to War appear to influence all these conditions via epigenetic mechanisms. Hence we argue that for a spectrum to be proposed, conditions in the spectrum need to be underpinned by similar or common Neuroimaging and neurobiological mechanisms.On this basis, it may be reasonable to include Borderline Personality Disorder within a broadly described bipolar spectrum. New details of the common Neurobiological mechanisms continue to emerge

Blaming Blamers: Differential Obligation To Punish For Third-Parties Compared To Victims

The present study examines the different ways we morally evaluate first-party (victims) and third-party (uninvolved observers) in judgement scenarios; when given the opportunity to punish or forgive a moral perpetrator. Participants were asked to read an interaction of individuals playing an economic game where one player cheats the other. Participants then read one of four accounts of either the player who was cheated punishing or forgiving the offender, or a third-party observer punishing or forgiving the offender. After reading the account the participants evaluated the judger in their scenario; we found that people are okay with victims who forgive or punish and third parties who punish, but participants saw third-parties who forgave as extremely immoral and sanctioned them for their decision. The results of this study support the theory that we hold third and first-parties to different moral norms; expecting third-parties to uphold what society believes is just, making punishment a rational protective choice for third-parties

Body Size Evolution of Oxyurid (Nematoda) Parasites: The Role of Hosts

Studying the diversification of body size in a taxon of parasites allows comparison of patterns of variation observed in the parasites with patterns found in free-living organisms. The distributions of body size of oxyurid nematodes (obligate parasites of vertebrates and invertebrates) are lognormally right-skewed, except for male oxyurids in invertebrates which show left-skewed distributions. In these parasitic forms, speciose genera do not have the smallest body sizes. Parasite body size is positively correlated with host body size, the largest hosts possessing the largest parasites. This trend is shown to occur within one monophyletic group of oxyurids, those of Old World primates. Comparative methods are used to take account of the effects of phylogeny. The use of multiple linear regression on distance matrices allows measurements of the contribution of phylogeny to the evolution of body size of parasites. Evolution of body size in female pinworms of Old World primates appears to be dependent only on the body size of their hosts. The tendency of parasite body size to increase with host body size is discussed in the light of the evolution of life-history traits

The Chief Resident Role in Emergency Medicine Residency Programs

Study Objectives: Although other specialties have examined the role of the chief resident (CR), the role and training of the emergency medicine (EM) CR has largely been undefined.Methods: A survey was mailed to all EM CRs and their respective program directors (PD) in 124 EM residency programs. The survey consisted of questions defining demographics, duties of the typical CR, and opinions regarding the level of support and training received. Multiple choice, Likert scale (1 strong agreement, 5 strong disagreement) and short-answer responses were used. We analyzed associations between CR and PD responses using Chi-square, Student’s T and Mann-Whitney U tests.Results: Seventy-six percent of CRs and 65% of PDs responded and were similar except for age (31 vs. 42 years; p<0.001). CR respondents were most often male, in year 3 of training and held the position for 12 months. CRs and PDs agreed that the assigned level of responsibility is appropriate (2.63 vs. 2.73, p=0.15); but CRs underestimate their influence in the residency program (1.94 vs. 2.34, p=0.002) and the emergency department (2.61 vs. 3.03, p=0.002). The majority of CRs (70%) and PDs (77%) report participating in an extramural training program, and those CRs who participated in training felt more prepared for their job duties (2.26 vs. 2.73; p=0.03).Conclusion: EM CRs feel they have appropriate job responsibility but believe they are less influential in program and department administration than PD respondents. Extramural training programs for incoming CRs are widely used and felt to be helpful. [West J Emerg Med. 2010; 11(2):120-125.

Trilingual conversations: a window into multicompetence

A recurrent theme in the literature on trilingual language use is the question of whether there is a specific “trilingual competence.” In this paper we consider this question in the light of codeswitching patterns in two dyadic trilingual conversations between a mother and daughter conducted in (Lebanese) Arabic, French, and English. Quantitative and qualitative analysis of codeswitching in both conversants shows that, despite the fact that both subjects are fluent in all three languages, uses of switching are significantly different for mother and daughter across a number of features, including relative frequency of different switch types, and the incidence of hybrid constructions involving items from two or more languages. The subjects appear to display qualitatively distinct profiles of competence in the trilingual mode. This in turn leads to the conclusion that the facts of trilingual language use are best characterized in terms of “multicompetence” (Cook, 1991). The paper concludes with some further reflections on the uniqueness of trilingual language use (an “old chestnut” in trilingualism research, cf. Klein, 1995)
