"克强指数"是英国著名政经杂志《经济学人》在 2010 年推出的用于评估中国 GDP 增长量的指标,由工业用电量、铁路货运量、中长期贷款按一定权重计算得到.根据重庆市经济发展特色,选取重庆市 1985—2014 年的相关经济发展指标,探讨重庆市经济增长与"克强指数"之间的动态关系,为客观公正评价重庆市经济发展情况提供思路. 相似文献

We propose an influence diagnostic methodology for linear regression models with stochastic restrictions and errors following elliptically contoured distributions. We study how a perturbation may impact on the mixed estimation procedure of parameters in the model. Normal curvatures and slopes for assessing influence under usual schemes are derived, including perturbations of case-weight, response variable, and explanatory variable. Simulations are conducted to evaluate the performance of the proposed methodology. An example with real-world economy data is presented as an illustration. 相似文献

We investigate the impacts of complex sampling on point and standard error estimates in latent growth curve modelling of survey data. Methodological issues are illustrated with empirical evidence from the analysis of longitudinal data on life satisfaction trajectories using data from the British Household Panel Survey, a national representative survey in Great Britain. A multi-process second-order latent growth curve model with conditional linear growth is used to study variation in the two perceived life satisfaction latent factors considered. The benefits of accounting for the complex survey design are considered, including obtaining unbiased both point and standard error estimates, and therefore correctly specified confidence intervals and statistical tests. We conclude that, even for the rather elaborated longitudinal data models that were considered, estimation procedures are affected by variance-inflating impacts of complex sampling. 相似文献

The establishment of the European Higher Education Area has involved specifying lists of professional competencies that programs are expected to develop, and with this the need for procedures to measure how every course within a higher education program is aligned with the program's competencies. We propose an instrument for characterizing this alignment, a process that we call assessing the relevance of a course. Using information from the course syllabus (objectives, contents and assessment scheme), our instrument produces indicators for characterizing the syllabus in terms of a competence list and for assessing its coherence. Because assessment involves quality, the results obtained can also be used to revise and improve the course syllabus. We illustrate this process with an example of a methods course from a mathematics teacher education program at a Spanish university. 相似文献

This paper details a semi-structured interview protocol that evaluators can use to develop a logic model of a program's services and outcomes. The protocol presents a series of questions, which evaluators can ask of specific program informants, that are designed to: (1) identify key informants basic background and contextual information, (2) generate logic model elements, (3) model program inputs, activities, outputs, and outcomes, (4) build a rational theory, (5) develop a program theory, (6) prioritize logic model elements, and (7) build a graphical or tabular logic model. The paper will also provide an example of how this approach was used to develop a logic model for a youth mentoring program. It is our hope and belief that with this interview protocol, novice evaluators will be able to generate comprehensive logic models like seasoned professional evaluators. 相似文献

An experiment was conducted to observe the influence of autonomic arousal on subsequent gambling behavior. Thirty-seven male
and 32 female regular Electronic Gaming Machine (EGM) players were recruited through newspaper advertisements. Participants
were randomly assigned to either: (1) a control condition, or (2) an experimental condition that introduced a loud white-noise
event (80 db) at fixed 120 s intervals throughout the 5-min EGM gambling session. Galvanic Skin Response (GSR) measurements
showed that the manipulation was successful in elevating autonomic arousal. The results showed differences in behavioral response
to the manipulation based on prior experience with gambling problems. Persons with many gambling problems had lower average
bet-sizes in the white-noise condition compared to the control, while those with few or no problems had higher average bet-sizes.
The results suggest that arousal may provide different signals to gamblers with few versus many problems. Gamblers with many
problems may interpret their arousal as a sign that they will soon lose money, while gamblers with few or no problems may
associate feelings of arousal exclusively with winning. 相似文献

Research and theory regarding the social facilitation effect generates the expectation that the presence of other gamblers (or co-actors) in a gaming venue is likely to intensify individual gambling behavior and magnify losses. Fifty male and 66 female participants (116 total) played a computer-simulated electronic gaming machine with a fixed winning sequence, followed by an indefinite losing sequence. Measures of the intensity of gambling behavior included the final payout (a direct measure of losses), average bet-size, number of trials played, and the speed of play. Some participants received false feedback from the computer designed to suggest that other gamers in adjacent rooms were playing and sometimes winning at the same game. Persons who received both sight and sound information, including winning bells and instant messages regarding the wins of other (fake) players, placed more bets and lost more money compared to the other conditions with less information. 相似文献

The Four Es is a 40-item scale measuring psychological risk for the development of problem gambling behavior. One-year follow-up interviews
(n = 395) from a previously reported phone survey in Queensland, Australia (n = 2,577) (Rockloff & Dyer, 2006) tested the ability of the Four Es instrument to prospectively identify persons who would later develop gambling problems.
Two groups of participants were selected for the 1-year follow-up interviews, including (1) persons who had gambling problems,
high-risk alcohol abuse problems, and/or substance abuse problems (abuse group); and (2) a random selection of other persons
from the original survey (random group). The results indicated that the “Excess” trait, which measures impulsive behavior,
was predictive of relative increases in gambling problems for both groups over the 1-year period. Additionally, the Four Es
questionnaire showed good psychometric properties in the surveys, with a test-retest reliability of r = .70 and a Cronbach’s alpha reliability of α = .90 and .92 in the original and follow-up interviews, respectively. 相似文献

This paper first identifies the determinants of spouses’ satisfaction levels within the household with respect to their leisure
time and, secondly, characterizes whether their preferences have some degree of altruistic or egoistic character in regard
to this particular satisfaction. To that end, it formulates a theoretical framework from the collective family model whose
stochastic formulations are estimated for 14 EU countries. The general empirical results first reveal that the presence of
children has a significantly negative impact on the leisure satisfaction of both spouses. Then, increases in individual incomes
lead to lower own leisure satisfaction levels. Both husbands and wives show egoistic behavior with respect to the labor and
non-labor incomes (wage rate) of their respective spouses’ satisfaction levels.
