Valuing the Arts: A Contingent Valuation Approach   总被引：5，自引：3，他引：2  

Eric Thompson  Mark Berger  Glenn Blomquist  Steven Allen 《Journal of Cultural Economics》2002,26(2):87-113

Government funding of the arts has received considerable attention in the United States in recent years. Efforts to cut funding to the National Endowment for the Arts and declining budgets for state arts agencies have raised questions about how much individuals value the arts. This paper applies the contingent valuation method to assess this value, using surveys of random households and of arts patrons. Our analysis estimated a mean willingness to pay (WTP) among all Kentucky households from $6 to$27, depending on the estimation technique used and on whether the scenario discussed is to increase arts performances by 25 per cent, or to avoid a 25per cent or 50 per cent decrease in the number of performances. Among arts patron households, the mean WTP ranges from $61 to $132.Consumer demand for arts performances in large part follows a predictable pattern. The likelihood of respondents agreeing to make the donation that is requested rises as the size of the donation decreases. The likelihood is higher to avoid a 50 per cent decline in performances than to avoid a 25 percent decline in performances. The mean WTP rises with income, and arts patron households have a much higher WTP than all households. WTP rises with on-site use factors such as frequency of attendance. The WTP also rises for arts patrons households with off-site use such as watching arts events on television or reading about the arts in newspapers and magazines.  相似文献   

An investigation of the relationship between public relations activities and budget allocation in public libraries     

Patricia Berger 《Information processing & management》1979,15(4):179-193

Due to the financial crisis many public libraries are experiencing, research was formulated to ascertain whether libraries could gain higher budget allocation if they employed public relations activities. Business and industry have successfully done so, openly acknowledging the importance of the public relations function and of its directing specialist. The following hypothesis was formulated: Libraries that engage in public relations activities will show a higher public support as evidence by a higher budget allocation than libraries who do not engage in public relations activities. The method of data collection was a twenty-six item questionnaire sent to Connecticut libraries servicing a population of twenty-five thousand or more. When the questionnaires were returned the answers were translated into a numerical code, giving each library a weighted composite score along with the budget allocation, which was considered in terms of percentages of the total town budget. The correlation coefficient (Pearson r) between public relations score (the weighted composite score) and budget allocation was calculated to be 0.53 with a standard deviation of 0.13; between public relations score and per capita expenditures was 0.75 with a standard deviation of 0.08 thus indicating a significant relationship. Summary of the findings: (1) The hypothesis is supported. (2) The activities that appear to closely correlate to a higher budget allocation are the managerial or administrative aspects of public relations: research, planning and evaluation. (3) The size of the population is not a critical variable influencing public relations activities. (4) The patterns of employment that seem to correlate to higher budget allocation are (a) full/part time specialist on staff, (b) possibly a joint combination of public relations/programming position; and (c) a high involvement of the Directors, Assistant Directors, and Trustees.  相似文献

A microfluidic device for on-chip agarose microbead generation with ultralow reagent consumption

Water-in-oil microdroplets offer microreactors for compartmentalized biochemical reactions with high throughput. Recently, the combination with a sol-gel switch ability, using agarose-in-oil microdroplets, has increased the range of possible applications, allowing for example the capture of amplicons in the gel phase for the preservation of monoclonality during a PCR reaction. Here, we report a new method for generating such agarose-in-oil microdroplets on a microfluidic device, with minimized inlet dead volume, on-chip cooling, and in situ monitoring of biochemical reactions within the gelified microbeads. We used a flow-focusing microchannel network and successfully generated agarose microdroplets at room temperature using the “push-pull” method. This method consists in pushing the oil continuous phase only, while suction is applied to the device outlet. The agarose phase present at the inlet is thus aspirated in the device, and segmented in microdroplets. The cooling system consists of two copper wires embedded in the microfluidic device. The transition from agarose microdroplets to microbeads provides additional stability and facilitated manipulation. We demonstrate the potential of this method by performing on-chip a temperature-triggered DNA isothermal amplification in agarose microbeads. Our device thus provides a new way to generate microbeads with high throughput and no dead volume for biochemical applications.  相似文献   

Construct Validity of Self-Reported Metacognitive Learning Strategies     

Jean-Louis Berger  Stuart A. Karabenick 《Educational Assessment》2016,21(1):19-33

Despite their significant contributions to research on self-regulated learning, those favoring online and trace approaches have questioned the use of self-report to assess learners' use of learning strategies. An important rejoinder to such criticisms consists of examining the validity of self-report items. The present study was designed to assess the validity of items to assess 9th-grade students' use of planning, monitoring, and regulation when studying math. To establish response process evidence of construct validity, cognitive interviews were coded to determine whether students' interpretations of the items were consistent with their intended meaning and whether their response choices were congruent with those interpretations. Evidence supported the construct validity of monitoring and regulation items, but to a lesser degree those designed to assess planning. We discuss implications of the evidence for the self-report assessment of learners' use of metacognitive strategies.  相似文献   

Grades degrade group coordination: deteriorated interactions and performance in a cooperative motor task     

Anne-Sophie Hayek  Claudia Toma  Sofia Guidotti  Dominique Oberlé  Fabrizio Butera 《European Journal of Psychology of Education - EJPE》2017,32(1):97-112

At school, pupils often cooperate on common projects and must coordinate their different individual actions. However, grades are pervasively used even in cooperative situations, which make the pupils’ differences in achievement and their relative rank salient and may reduce their inclination to work constructively with others. Thus, we hypothesized that grades would elicit disruptive interactions and reduce performance in a cooperative cognitive-motor task necessitating inter-individual coordination of members. In a study with 5th graders, grades (vs. a neutral concept) were primed at the onset of a cooperative group interaction. Results showed that, although pupils were set to work cooperatively, priming grades (vs. neutral concepts) harmed inter-individual coordination by eliciting more negative dominant behaviours among pupils during interactions, which decreased group performance.  相似文献

L’apprentissage précoce des langues : Des pratiques sociologiquement et politiquement marquées     

Dominique Groux 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2007,52(1-2):107-123

Throughout the world there is a great diversity of curricula for introducing early foreign language training more or less intensively. These curricula correspond to different pedagogical approaches. But these pedagogical choices are not neutral. They are the result of political choice. They are also sociologically discriminatory. The author studies and contrasts various forms of language training of certain countries and within the same countries (for example, the correlation between bilingual training and private schools, or the choice of bilingual education as a political goal). She proposes a scale for classifying the kinds of early foreign language training, depending on sociological criteria and political choice.  相似文献   

Efficiency of Targeted Multistage Calibration Designs Under Practical Constraints: A Simulation Study     

Stphanie Berger  Angela J. Verschoor  Theo J. H. M. Eggen  Urs Moser 《Journal of Educational Measurement》2019,56(1):121-146

Calibration of an item bank for computer adaptive testing requires substantial resources. In this study, we investigated whether the efficiency of calibration under the Rasch model could be enhanced by improving the match between item difficulty and student ability. We introduced targeted multistage calibration designs, a design type that considers ability‐related background variables and performance for assigning students to suitable items. Furthermore, we investigated whether uncertainty about item difficulty could impair the assembling of efficient designs. The results indicated that targeted multistage calibration designs were more efficient than ordinary targeted designs under optimal conditions. Limited knowledge about item difficulty reduced the efficiency of one of the two investigated targeted multistage calibration designs, whereas targeted designs were more robust.  相似文献
