A Survey of the Foreign Policies of Herbert Hoover During his Presidency

This paper is a survey of the foreign policy of Herbert Hoover during his presidency. He is often associated only with domestic issues and the Great Depression, and his foreign policies have been somewhat unfamiliar. The more reading that was done, the more interesting and absorbing became his ideas and attempts to formulate his actions. The topic was chosen partially because of an intense interest in American history. There has been--and still is--a violently pro-Hoover or anti-Hoover sentiment and criticism regarding this former president. Another reason for this selection is that Mr. Hoover is a contemporary. There may be added personal interest because he was born in a little Iowa town near my former home. I have attempted to present a survey of the Hoover foreign policies as he expressed them and attempted to carry them out. There has been considerable amount written by historians and scholars on this subject but in the final analysis, it is based primarily on the Hoover Memoirs and State Papers which have been extensively used and quoted to establish authenticity and to illustrate the particular policy under discussion. Insofar as it is possible, each foreign policy will be discussed individually and in the order in which it presented itself

Does the Cambridge Automated Neuropsychological Test Battery (CANTAB) Distinguish Between Cognitive Domains in Healthy Older Adults?

The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a semiautomated computer interface for assessing cognitive function. We examined whether CANTAB tests measured specific cognitive functions, using established neuropsychological tests as a reference point. A sample of 500 healthy older (M = 60.28 years, SD = 6.75) participants in the Tasmanian Healthy Brain Project completed battery of CANTAB subtests and standard paper-based neuropsychological tests. Confirmatory factor analysis identified four factors: processing speed, verbal ability, episodic memory, and working memory. However, CANTAB tests did not consistently load onto the cognitive domain factors derived from traditional measures of the same function. These results indicate that five of the six CANTAB subtests examined did not load onto single cognitive functions. These CANTAB tests may lack the sensitivity to measure discrete cognitive functions in healthy populations or may measure other cognitive domains not included in the traditional neuropsychological battery

Effect of Standard vs Intensive Blood Pressure Control on Cerebral Blood Flow in Small Vessel Disease The PRESERVE Randomized Clinical Trial

Importance: Blood pressure lowering is considered neuroprotective in patients with cerebral small vessel disease, however more “intensive” regimens may increase cerebral hypoperfusion. We examined the effect of intensive vs. standard blood pressure treatment on cerebral perfusion in severe small vessel disease patients. Objective: To determine whether intensive vs. standard blood pressure lowering over 3 months causes decreased cerebral perfusion. Design, Setting and Participants: This randomised, parallel, controlled, blinded-outcomes clinical trial took place in 2 English university medical centres. A central, online randomisation system (1:1 ratio) allocated grouping. 70 hypertensive patients with MRI confirmed symptomatic lacunar infarct and confluent white matter hyperintensities were recruited between 2012 and 2015, and randomised (36/34 in standard/intensive arms). Analysable data were available in 62 patients, 33/29 in the standard/intensive groups respectively, for intention to treat analysis. This experiment examines the 3 month follow-up period. Intervention: Patients were randomised to “standard” (systolic=130-140mmHg) or “intensive” (systolic=<125mmHg) blood pressure targets, to be achieved through medication regimen changes. Main Outcome and Measure: Cerebral perfusion was determined using arterial spin labelling; the primary end point was change in global perfusion between baseline and 3 months, compared between treatment groups by ANOVA. Linear regression compared change in perfusion against change in blood pressure. MR scan analysis was blinded to treatment arm. Results: Patients were 69.3 years old (mean) and 59.7% male. Mean(SD) systolic blood pressure reduced by 8(12) and 27(17)mmHg in the standard/intensive groups, respectively (p<0.001), with achieved pressures of 141(13) and 126(10) mmHg respectively. Change in global perfusion did not differ between treatment arms: standard, mean(SD) (ml/min/100g)= -0.5(9.4); intensive, 0.7(8.6), partial ETA2= 0.004, 95% CI= -3.6–5.8, p= 0.63. No differences were observed when analysis examined grey/white matter only, or was confined to those achieving target blood pressure. The number of adverse events did not differ between treatment groups (standard/intensive mean(SD)= .21(.65)/.32(.75), p=.44). Conclusions and Relevance: Intensive blood pressure lowering did not reduce cerebral perfusion in severe small vessel disease.This study was funded by a joint Stroke Association/British Heart Foundation program grant (TSA BHF 2010/01).

A multifaceted approach to investigating pre-task planning effects on paired oral test performance

Despite the growing popularity of paired format speaking assessments, the effects of pre-task planning time on performance in these formats are not yet well understood. For example, some studies have revealed the benefits of planning but others have not. Using a multifaceted approach including analysis of the process of speaking performance, the aim of this paper is to investigate the effect of pre-task planning in a paired format. Data were collected from 32 students who carried out two decision-making tasks in pairs, under planned and unplanned conditions. The study used analyses of rating scores, discourse analytic measures, and conversation analysis (CA) of test-taker discourse to gain insight into co-constructing processes. A post-test questionnaire was also administered to understand the participants’ perceptions toward planned and unplanned interactions. The results from rating scores and discourse analytic measures revealed that planning had limited effect on performance, and analysis of the questionnaires did not indicate clear differences between the two conditions. CA, however, identified the possibility of a contrastive mode of discourse under the two planning conditions, raising concerns that planning might actually deprive test-takers of the chance to demonstrate their abilities to interact collaboratively

Rapid evolution of virulence and drug resistance in the emerging zoonotic pathogen Streptococcus suis

Background: Streptococcus suis is a zoonotic pathogen that infects pigs and can occasionally cause serious infections in humans. S. suis infections occur sporadically in human Europe and North America, but a recent major outbreak has been described in China with high levels of mortality. The mechanisms of S. suis pathogenesis in humans and pigs are poorly understood. Methodology/Principal Findings: The sequencing of whole genomes of S. suis isolates provides opportunities to investigate the genetic basis of infection. Here we describe whole genome sequences of three S. suis strains from the same lineage: one from European pigs, and two from human cases from China and Vietnam. Comparative genomic analysis was used to investigate the variability of these strains. S. suis is phylogenetically distinct from other Streptococcus species for which genome sequences are currently available. Accordingly, ,40% of the ,2 Mb genome is unique in comparison to other Streptococcus species. Finer genomic comparisons within the species showed a high level of sequence conservation; virtually all of the genome is common to the S. suis strains. The only exceptions are three ,90 kb regions, present in the two isolates from humans, composed of integrative conjugative elements and transposons. Carried in these regions are coding sequences associated with drug resistance. In addition, small-scale sequence variation has generated pseudogenes in putative virulence and colonization factors. Conclusions/Significance: The genomic inventories of genetically related S. suis strains, isolated from distinct hosts and diseases, exhibit high levels of conservation. However, the genomes provide evidence that horizontal gene transfer has contributed to the evolution of drug resistance
