A Call to Act Together

This is the text of the message issued by the 11th Assembly of the World Council of Churches, meeting in Karlsruhe, Germany, from 31 August to 8 September 2022. In their message, delegates stated that all are called by Christ's love to repentance, reconciliation, and justice in the face of war, inequality, and sins against creation.     

Maximum likelihood additivity analysis

A maximum likelihood estimation procedure was developed to fit unweighted and weighted additive models to conjoint data obtained by the categorical rating, the pair comparison or the directional ranking method. The scoring algorithm used to fit the models was found to be both reliable and efficient, and the program MAXADD is capable of handling up to 300 parameters to be estimated. Practical uses of the procedure are reported to demonstrate various advantages of the procedure as a statistical method.The research reported here was supported by Grant A6394 to the author from the Natural Sciences and Engineering Research Council of Canada. Portions of this research were presented at the Psychometric Society meeting in Iowa City, Iowa, in May, 1980.Thanks are due to Jim Ramsay, Justine Sergent and anonymous reviewers for their helpful comments.Two MAXADD programs which perform the computations discussed in this paper may be obtained from the author.     

Providing Practicing Teachers Classroom Management Professional Development in a Brief Self-Study Format

This study examined the impact of a time efficient self-study method for providing practicing teachers with job-embedded professional development targeting specific classroom management skills. The training method employed print packets and videotapes that provided models of effective classroom management strategies for instruction-giving, praise, and time out. Participants were three master’s level speech therapists certified to teach speech and language delayed preschool children. The training materials were evaluated through observations of the teachers’ implementation of targeted practices in a multiple baseline across participants. Results indicated increases in all participants use of the management skills after training. The results suggest that this type of training method may help teachers increase their use of effective classroom management procedures. It is potentially noteworthy that the training program examined herein was largely teacher managed and was quite brief. Future directions and limitations of the study are discussed.Natalie J. Slider is now at Brownsburg Community School Corporation.     

Two in one or one in two? Pushing off from Jung with Wolfgang Giegerich

This paper responds to a recent paper by Wolfgang Giegerich entitled ‘Two Jungs: apropos a paper by Mark Saban’. Giegerich disputes my assertion that the ‘rigorous notion’ at the heart of his psychology ‘finds no source in Jung's psychology, implicit or explicit’. In order to do this he posits the existence of two Jungs, an exoteric Jung and an esoteric Jung. The implications of Giegerich's binary scission of Jung are explored in this paper, and show that the tendency to exalt one Jung while disparaging the other betrays a comprehensive blindness toward the contradictory complexity of Jung's psychology as a whole. It is suggested that this blindness is the consequence of Giegerich's systematic prioritization of a neo‐Hegelian agenda that is in profound conflict with the telos of Jung's psychology.     

乳腺癌术式的演变及其最佳选择

乳腺癌作为女性常见的恶性肿瘤之一,一直是肿瘤学界研究的热点和焦点。手术作为其基本的治疗手段,术式几经改变。通过对乳腺癌术式演变的历史回顾,认为正是由于对乳腺癌生物学行为研究的不断深入,使得乳腺癌手术切除范围更趋于规范和科学。而由生物医学模式向生物—心理—社会医学模式的转变,以及循证医学(EBM)研究的开展,更促进了乳腺癌术式的不断改进,以最大程度减少并发症,获得更为满意的疗效。     

The impact of different sources of social support on academic performance: Intervening factors and mediated pathways in the case of master's thesis

IntroductionAcademic failure and dropout are pervasive challenges at all levels of the education system. Research so far pointed out different aspects of this large phenomenon. On the one hand, some scholars have argued that social support is a key factor to foster learning and persistence. On the other hand, some other scholars have rather highlighted the role of student motivation and engagement itself in improving performance on academic tasks. In this article, we tested theoretical models that combine the two approaches in a whole process.AimsWe aimed at clarifying (1) the specific contribution of several sources of perceived social support to academic performance, and (2) the mediation role of motivation and engagement in the relationships between perceived social support and performance.MethodThe sample consisted of 226 last year university students. Structural equation modeling analyses were used to test the hypothesized associations.ResultsStructural equation modeling analysis revealed that institutional and supervisor support were associated with motivation, which in turn predicted greater behavioral, cognitive and emotional engagement. Further, behavioral engagement was the unique contributor of academic performance at the master's thesis.ConclusionThe results clarify the specific contribution of different sources of perceived social support and underline the importance of the supervisor and the institution. They also underline the importance of considering different sources of perceived social support at the same time. Finally, theoretical assumptions concerning the mediational role of motivation were confirmed.     

Relationship between response rate and reinforcement frequency in variable-interval schedules: II. Effect of the volume of sucrose reinforcement

Three rats were exposed to variable-interval schedules specifying a range of different reinforcement frequencies, using three different volumes of .32 molar sucrose (.10, .05, and .02 milliliters) as the reinforcer. With each of the three volumes, the rates of responding of all three rats were increasing, negatively accelerated functions of reinforcement frequency, the data conforming closely to Herrnstein's equation. In each rat the value of the constant K_H, which expresses the reinforcement frequency needed to obtain the half-maximal response rate, increased with decreasing reinforcer volume, the values obtained with .02 milliliters being significantly greater than the values obtained with .10 milliliters. The values of the constant R_max, which expresses the theoretical maximum response rate, were not systematically related to reinforcer volume. The effect of reinforcer volume upon the relationship between response rate and reinforcement frequency is thus different from the effect of the concentration of sucrose reinforcement: In a previous experiment (Bradshaw, Szabadi, & Bevan, 1978) it was found that sucrose concentration influenced the values of both constants, R_max increasing and K_H decreasing with increasing sucrose concentration.     

College women’s value orientations toward family, career, and graduate school

This study was designed to examine how college women’s valuing of graduate education predicted their intentions to attend graduate school, using a new measure of the valuing of graduate school. A second purpose was to assess relations of college women’s perceptions of the relative importance of family and career to their valuing of graduate education. Two hundred and sixteen college women completed a newly developed survey that assessed these constructs. The items assessing task values were designed to assess components of task value defined by Eccles et al. (1983). Reliability and factor analyses demonstrated that the instrument adequately measured different components of task value. Multiple regression analyses demonstrated that components of task value predicted intentions to attend graduate school. The women were strongly career-oriented, and their orientations to career related positively to their valuing of graduate education.     

郭璞易学思想考

在易学史上,郭璞精湛的易占一直为人推重,而其颇具特色的易学思想却往往被忽视,或语焉不详。笔者在深入研读郭璞诗赋文的基础上,结合其行状,对其易学思想予以全面梳理。本文主要做了三项工作：一是结合郭璞的诗赋,指出郭璞对周易义理的承袭与发挥;一是结合《晋书》本传、郭璞《易洞林》,从取象运数、据象成辞及阴阳灾异说两方面,深入阐析郭璞对焦（赣）、京（房）、管（辂）易象数学的继承与发展;一是结合郭璞的行状,指出郭璞在易占实践上为改革易占方法、完善易占辞以适应现实需要所作出的贡献, 从而表明郭璞是位既重义理又重象数,既重理论又重实践的易学大师。
