On the Logical Positivists' Theory of Truth: The Fundamental Problem and a New Perspective

The present article purports to show that the protocol sentence debate, pursued by some leading members of the Vienna Circle in the mid-1930s, was essentially a controversy over the explanation and the real significance of the concept of truth. It is further shown that the fundamental issue underlying the discussions about the concept of truth was the relationship between form and content, as well as between logic/language and the world. R. Carnap was the philosopher who most explicitly and systematically attempted to come to grips with this problem. It is shown that the form-content distinction pervades the three most important phases of Carnap's philosophical development: the structuralist (in Der logische Aufbau der Welt), the syntactical and the semantical. His final semantical stance is essentially determined by the concept of linguistic frameworks. The article purports to demonstrate that this concept cannot be dispensed with in philosophy, but that Carnap failed to work out its ontological implications. Finally, the concept of an internal ontology is briefly delineated. This revised version was published online in August 2006 with corrections to the Cover Date.     

Peer and college-student tutoring as reinforcement in a token economy

Eighteen second-grade children initially received feedback in the form of nonredeemable tokens for reducing their disruptive classroom behavior. Four types of tutoring were then introduced in a Latin Square Design: noncontingent tutoring from fifth-grade peers, contingent peer tutoring, noncontingent college tutoring, and contingent college tutoring. No significant difference was found in the level of disruptive behavior of those children tutored by fifth-grade peers or college students, but contingent tutoring was significantly effective in reducing disruptive classroom behavior.     

材料的几何属性差异对3—7岁儿童分类标准影响的研究

以７３名３—７岁儿童为被试,通过变换分类材料的几何属性（形状或大小）的差异程度,采用自由分类方法,探讨材料差异程度的变换对儿童分类标准的影响。结果表明：３—７岁儿童的分类标准均受分类材料几何属性差异变化的影响。３岁儿童的分类标准几乎完全随分类材料的变换而改变;４—５岁儿童的分类标准主要表现为随分类材料的变换而改变;６—７岁儿童的分类标准虽然有随分类材料的变换而改变的趋势,但已经表现出比较稳定的按形状分类;５—６岁是儿童分类能力发展的质的飞跃阶段。     

RELIGION AND THE THEORIES OF SCIENCE: A RESPONSE TO BARBOUR

Abstract. This paper offers a detailed response to “Religion and the Theories of Science” in Barbour's Gifford Lectures I. Topics include: complementarity, indeterminacy, parts and wholes, and Bell's theorem in quantum theory; metaphysical issues raised by relativity theory and thermodynamics, principally the problem of temporality and “top-down” versus “bottom—up” causality; design arguments and the origins of the universe in astronomy and creation; and God's action in the context of evolution and continuing creation. Areas of agreement and disagreement between Barbour and myself over philosophical and theological implications are presented, and endnotes indicate further areas of conversation.     

Vertical vs horizontal bullying: A need of socio‐interactive ethical trainings at workplace

Bullying at workplaces is a growing problem associated with several antecedents and outcomes of psychological disorders. Extant literature shows the relationship of victimization with the owning‐up curriculum to confront bullying, but so far there is little research to cure the issue of bullying through ethics and there is no study to check the impact of ethical lessons and exercises in training materials to curb bullying at workplace. The current paper is based on a literature review of aggression and bullying, and chiefly addresses the HR practices in rescuing the people from peer victimization. Conceptually segregating supervisor‐subordinate (vertical) and peer‐peer (horizontal) bullying psychology, this paper attempts to see what possible corrective steps can be taken by senior managers, supervisors and psychologists to resolve this critical problem through interior capacities. In this paper, we have developed three propositions for conducting a future empirical investigation in connection to a cohort study. By addressing the counterproductive/deviant behavior, the present report is likely to be beneficial for psychology scientists and HR practitioners in noticing and resolving the bullying issues at the workplace for the well‐being of employees.     

WHY WE SHOULD CARE ABOUT EVOLUTION AND NATURAL HISTORY

Historians play it safe. Complex issues are dissected while analytical distance keeps stakeholders at bay. But the relevance of historical research may be lost in caution and failure to engage with a wider audience. We can't afford that. We have too much to offer and too much at stake. We need to take the discussion of science and religion beyond our own professional circles. Peter Harrison's The Territories of Science and Religion gives us an opportunity to do so. We can use his book to understand why people consistently get the relation wrong. However, we need to take the next step ourselves, involve historians in the common academic goal, across disciplines, to make sense of the world around us and make that combined knowledge truly useful. Evolution and natural history might help to that effect.     

Material handling device selection in cellular manufacturing

This paper presents a new multi‐criteria decision model for the material handling device (MHD) selection problem in cellular manufacturing systems. Given a set of manufacturing cells based on several automatic work‐centres, the technique makes it possible to select a particular MHD for each cell in an integrated way, with different constraints being taken into consideration. The approach is based on two different multi‐attribute analyses executed with analytic hierarchy process (AHP) methodology, and a final integer linear programming including important limitations faced by the designer when making MHD investment decisions. An example using real data is provided to illustrate this methodology. Copyright © 2002 John Wiley & Sons, Ltd.     

血浆纤维蛋白原水平在胃癌诊断中的临床意义

通过检测血浆纤维蛋白原（FIB）水平及血清肿瘤相关物质（TAM）水平,探讨血浆FIB在胃癌患者中的水平及临床意义.结果显示：胃癌患者较胃良性肿瘤、健康体检者的FIB、TAM水平高（P＜0.05）,后二者比较差异无统计学意义（P＞0.05）;FIB和TAM在胃癌中的水平与临床分期、淋巴结转移、远处转移有关,其差异均有统计学意义（P＜0.05）,而与年龄、性别、分化程度无关（P＞0.05）;FIB与TAM水平具有相关性（r=0.65,P＜0.05）.因此,血浆FIB水平有望成为胃癌患者有临床价值的标志物.     

ON EVOLUTION AND CREATION: PROBLEM SOLVED? THE POLISH EXAMPLE

We present the results of research carried out as a part of the project Current Controversies about Human Origins: Between Anthropology and the Bible, which focused on the supposed conflict between natural sciences and some branches of the humanities, notably philosophy and theology, with regard to human origins. One way to tackle the issue was to distribute a questionnaire among students and teachers of the relevant disciplines. Teachers of religion and the natural sciences (biology, chemistry, and physics) and students of theology, philosophy, and the natural sciences (specializing in biology and/or anthropology) were asked to answer eleven questions concerning the perception of the conflict between evolutionism and creationism, the definitions of creation and evolution, the existence of a human spiritual element, and the ways of interpreting the Bible, especially the first chapters of the book of Genesis. We present selected results of this questionnaire.     

Morphological and magnetic response of copper-substituted nickel ferrite nanoparticles

Ferrite nanoparticles are interesting materials owing to their unique physical and chemical properties. The metal-doped ferrites have well-defined structures and magnetic response, such as high permeability for a specific frequency range. In this study, copper-substituted nickel ferrite (Ni_1?xCu_xFe₂O₄) nanoparticles with a compositional range of 0?≤?x?≤?0.3 were synthesised through a co-precipitation technique. Metal chlorides were used as precursors and NaOH as a precipitating agent for the growth of ferrite nanoparticles. To minimise the internal stresses and maximise the magnetic response, ferrite nanoparticles were annealed in a furnace at 700°C for 6 h. The structural and magnetic response of Ni_1?xCu_xFe₂O₄ ferrite with different values of x were investigated using Scanning Electron Microscopy (SEM), Fourier Transform Infrared spectroscopy (FT-IR), Vibrating Sample Magnetometer (VSM) and X-ray Diffraction (XRD) techniques. XRD analysis confirmed the formation of cubic spinel structure of single phase for all the compositions. The lattice constant decreased with increase in the value of x. FT-IR study showed two main metal oxygen bonds in the range 500–700 cm^?1 confirming the formation of a single-phase cubic inverse structure of Cu-substituted Ni ferrite. VSM results revealed the formation of ferrimagnetic nanoparticles. The optical and magnetic response of the ferrite nanoparticles changed with Cu content.
