Practice schedule and cognitive style interaction in learning a maze task

In the present study the effects of contextual interference on the retention and transfer performance of reflectives and impulsives on a maze task were studied. Forty-seven subjects were randomly assigned to either a high contextual interference group or to a low contextual interference group. Within the two groups subjects were further classified according to their preferred modes of responding. Retention and transfer were measured immediately following practice and after a 4-week delay. The dependent variables were tracing time and errors. Reflectives made fewer errors and moved more quickly after practising under conditions of high contextual interference. Impulsives tended to have fewer errors after practising under conditions of high contextual interference but moved more slowly. Based on these results it was suggested that trainers consider individual differences in reflectivity-impulsivity before designing particular practice schedules

On the Neocomian and the Wealden Rocks in the Jura and in England

In June, 1827, Dr. W. H. Fitton read before the Geological Society of London the following statement:—"It is obvious that, during a period of time sufficient for the accumulation of the Wealden, the deposition of matter in the adjacent seas could not have been inconsiderable; so that we might expect to find, interposed between the strata which then formed the bottom of the sea and the Lower Greensand, a series of beds coeval with the Wealden in point of date, but differing from it in possessing the characters of a marine deposit, and including marine shells and other productions of salt water; with which, near the shore, the productions of the land, or even the freshwater shells of the rivers, might be occasionally intermixed. . 1st. That the Wealden and its marine equivalent could not both be found in the same place; and consequently (since we have the former in England) that the marine beds of that date are not to be expected generally in this country; 2dl

Taxation - Federal Income Tax Deductibility of Interest on Debentures Issues as a Dividend

Taxpayer, a wholly-owned subsidiary corporation, had filed consolidated returns with its parent prior to 1934. When Congress abolished consolidated returns in that year, the subsidiary issued 6% debentures as a dividend to the parent company and subsequently deducted the interest paid on these bonds. The Commissioner claimed the interest payments were really dividends and were not deductible. The Tax Court upheld the Commissioner pointing out the tax-saving motive, absence of new investment, and parent-subsidiary relationship as factors indicating that no genuine debtor-creditor relationship existed. On appeal, held, reversed. The debentures involved were conventional in form and created a valid indebtedness. Kraft Foods Co. v. Commissioner, (2d Cir. 1956) 232 F. (2d) 118

Gigaflop performance on a CRAY-2: Multitasking a computational fluid dynamics application

The methodology is described for converting a large, long-running applications code that executed on a single processor of a CRAY-2 supercomputer to a version that executed efficiently on multiple processors. Although the conversion of every application is different, a discussion of the types of modification used to achieve gigaflop performance is included to assist others in the parallelization of applications for CRAY computers, especially those that were developed for other computers. An existing application, from the discipline of computational fluid dynamics, that had utilized over 2000 hrs of CPU time on CRAY-2 during the previous year was chosen as a test case to study the effectiveness of multitasking on a CRAY-2. The nature of dominant calculations within the application indicated that a sustained computational rate of 1 billion floating-point operations per second, or 1 gigaflop, might be achieved. The code was first analyzed and modified for optimal performance on a single processor in a batch environment. After optimal performance on a single CPU was achieved, the code was modified to use multiple processors in a dedicated environment. The results of these two efforts were merged into a single code that had a sustained computational rate of over 1 gigaflop on a CRAY-2. Timings and analysis of performance are given for both single- and multiple-processor runs

Stressors in anaesthesiology: development and validation of a new questionnaire: A cross-sectional study of Portuguese anaesthesiologists

BACKGROUND: Stress in anaesthesiologists is a common and multifactorial problem related to patients, colleagues and organisations. The consequences of stress include depression, work-home conflicts and burnout. Reduction in stress can be achieved by reducing the number and magnitude of stressors or by increasing resilience strategies. OBJECTIVES: We have created the self-reporting 'Stress Questionnaire in Anaesthesiologists' (SQA), to qualify the sources of stress in anaesthesiologists' professional lives, and measure the level of associated stress. Our study aimed to develop and validate the SQA using exploratory and confirmatory factor analyses. Construct validity was assessed through correlations between SQA and negative psychological outcomes as well as by comparing perception of stress among different known groups. DESIGN: A questionnaire-based cross-sectional, correlational, observational study. SETTINGS: The study was conducted between January 2014 and December 2014, throughout different anaesthesia departments in Portuguese hospitals. Data collection was from a representative subset at one specific time point. PARTICIPANTS: A sample of 710 anaesthesia specialists and residents from Portugal. MAIN OUTCOME MEASURES: The primary outcome measure was to identify specific stressors in anaesthesiologists. Secondary outcome was the association between stressors and burnout, depression symptoms, anxiety, stress, rumination, satisfaction with life and functional impairment. RESULTS: The exploratory analysis showed the SQA is a tri-dimensional instrument and confirmatory analysis showed the tri-dimensional structure presented good model fit. The three dimensions of SQA correlated positively with other stress measures and burnout, but negatively with satisfaction with life. CONCLUSION: SQA is a well adjusted measure for assessing stressors in anaesthesia physicians and includes clinical, organisational and team stress factors. Results showed that the SQA is a robust and reliable instrument.info:eu-repo/semantics/publishedVersio

Success and failure in programming with two young adult groups

Thesis (M.S.)--Boston UniversityThe purpose of this thesis is to study those successful and unsuccessful programs in two young adult groups as viewed by the members, advisors and executive directors of the Lynn Jewish Community Center and the Hecht House of Boston. A consideration of those elements which contribute toward successful programming will also be included in this study which is based primarily upon two co-ed groups - the 1953 young adult group at the Hecht House and the group at the Lynn Center during the years 1953-55
