一种基于Rasch模型的Angoff方法及其应用

水平厘定方法在近二十年来发展迅速,其中Angoff方法的应用最为广泛。该文在已有的方法上提出了一种基于Rasch模型的改进的Angoff方法,该方法使用Rasch模型来估计典型学生的位置,通过均方残差等方法剔除不一致的裁判。文章最后详细阐述了该方法在香港全港性系统评估中的应用。     

‘Is’–‘Ought’ Derivations and Ethical Taxonomies

Hume seems to claim that there does not exist a valid argument that has all non-ethical sentences as premises and an ethical sentence as its conclusion. Starting with Prior, a number of counterexamples to this claim have been proposed. Unfortunately, all of these proposals are controversial. Even the most plausible have a premise that seems like it might be an ethical sentence or a conclusion that seems like it might be non-ethical. Since it is difficult to tell whether any of these counterexamples are genuine, we need a taxonomy that sorts out ethical sentences from non-ethical ones. We need to know the difference between an ‘Is’ and an ‘Ought’. In the first part of the paper, I establish the need for a taxonomy. I consider some of the most influential ‘Is’–‘Ought’ derivations. These include proposals by Prior and Searle. I argue that each proposal has a premise whose status as ethical or non-ethical is difficult to determine. In the second part of the paper, I consider taxonomies proposed by Karmo and Maitzen. I argue against both taxonomies. I end with the claim that we need a taxonomy of ethical sentences and that none of the current proposals are adequate.

Turning up the volume on the property view of sound

In the present article, I show that sounds are properties that are not physical in a narrow sense. First, I argue that sounds are properties using Moorean-style arguments and defend this property view from various arguments against it that make use of salient disanalogies between sounds and colors. The first disanalogy is that we talk of objects making sounds but not of objects making colors. The second is that we count and quantify over sounds but not colors. The third is that sounds can survive qualitative change in their auditory properties, but colors cannot survive change in their chromatic properties. Next, I provide a taxonomy of property views of sound. As the property view of sound has been so rarely discussed, many of the views available have never been articulated. My taxonomy will articulate these views and how they are related to one another. I taxonomize sounds according to three characteristics: dispositional/non-dispositional, relational/non-relational and reductive/non-reductive. Finally, mirroring a popular argument in the color literature, I argue that physical views in the narrow sense are unable to accommodate the similarity and difference relations in which sounds essentially stand. I end replying to three objections.     

Effects of Differential Item Functioning on Examinees' Test Performance and Reliability of Test

Simulations were conducted to examine the effect of differential item functioning (DIF) on measurement consequences such as total scores, item response theory (IRT) ability estimates, and test reliability in terms of the ratio of true-score variance to observed-score variance and the standard error of estimation for the IRT ability parameter. The objective was to provide bounds of the likely DIF effects on these measurement consequences. Five factors were manipulated: test length, percentage of DIF items per form, item type, sample size, and level of group ability difference. Results indicate that the greatest DIF effect was less than 2 points on the 0 to 60 total score scale and about 0.15 on the IRT ability scale. DIF had a limited effect on the ratio of true-score variance to observed-score variance, but its influence on the standard error of estimation for the IRT ability parameter was evident for certain ability values.     

A Taxonomy of Anger-Related Behaviors in Young Adults

In 2 studies, we investigated the occurrence of anger-related behaviors and their relationship to emotional, performance-related, and situational variables. In the first study, we constructed a comprehensive taxonomy of behaviors associated with anger, and we examined the occurrence of the resulting behavior categories as a function of several independent variables. A total of 8 distinct behavior categories were identified, 3 aggressive and 5 nonaggressive. Our results also demonstrated that fight (including both verbal and physical aggression) and flight behaviors occurred most frequently. Physical aggression, however, occurred most frequently in an inhibited form, in response to the emotion of anger (as compared to the emotion of irritation), and when the anger was intense. A second study was conducted to replicate and extend the findings of Study 1. The results suggest that the taxonomy, as derived in Study 1, is comprehensive and allows for a reliable categorization. Moreover, it appeared that fight and flight behaviors occurred most frequently if the target at whom one is angry was present. The following reduction rules were used: (a) responses that differed only in the order of the words were put together; (b) singular and plural items were joined; (c) responses that differed only in verbs such as “to be,” “to become” or “to do” were grouped together; (d) responses that differed only syntactically (verb, noun or adjective) were grouped together; (e) responses that differed only with respect to an article, a preposition, or a possessive word were grouped together; (f) and a few specific rules were used (e.g., yourself = myself; self = auto). The complete coding manual is available upon request from the first author. This number differed across proportions because it depended on the number of participants assigned to each of the experimental questionnaires. Our initial analyses contained a participant-specific random intercept, so as to take into account individual differences in the propensity to use each of the behavior categories. Inclusion of a random intercept appeared to yield a significant improvement in model fit for two of the eight behavior categories. However, because analyses with a random and with a fixed intercept yielded similar conclusions, we decided to select the most parsimonious model, namely the one without a random intercept. The total number of participant–performance–instrumentality combinations equals 504 (i.e., 84×6) because all 84 participants had to answer six questions.     

Multiculturalism and Group Therapy in the United States: A Social Constructionist Perspective

Multiculturalism encourages the inclusion of the broad range of cultural differences that exist in society into our therapeutic dialogues. This paper examines multicultural group therapy through the perspective of social constructionism. Emphasis is given to the unacknowledged and unspoken imbalance of power that exists in psychotherapeutic contexts. The concepts of multiple individual identity and cultural representation are discussed and illustrated with case examples. Clinical considerations for the multicultural group therapist are provided.     

Hume on the Standard of Virtue

Among those sympathetic to Hume'smoral philosophy, a general consensus hasemerged that his first work on the topic,A Treatise of Human Nature, is his best. Hislater work, An Enquiry Concerning thePrinciples of Morals, is regarded as scaleddown in both scope and ambition. In contrastto this standard view, I argue that Hume'slater work offers a more sophisticated theoryof moral evaluation. I begin by reviewing theTreatise theory of moral evaluation tohighlight the reasons why commentators find socompelling Hume's account of the corrections wemake to our moral sentiments. The method isendorsed by philosophers such as Henry DavidAiken and Annette C. Baier because, theyallege, it shows that moral sentiments reflecta process of judgment that includes thepossibility of corrigibility and ofjustification. But Hume's method of correctionfalls short and does not establish why thesentiments conforming to the standard of virtueshould count as moral judgments. In the secondEnquiry, Hume lays out a different set ofcriteria, including not only the need forcertain virtues of good judgment but attentionto the particular cultural and historicalorigins of the norms governing the virtues ofgood judgment. Hume's attention to diversityin evaluative outlook in his more matureposition takes seriously the relation betweenmoral authority and public debate.
