初中生学习化学兴趣的发展趋势

针对目前初中化学教学中学生因缺乏应有的学习兴趣而导致学习动力不足和影响其个性和谐发展的问题，运用现代教育学、心理学的理论，结合初中生的心理特点和化学学科特点，提出把初中生学习化学兴趣提到学生稳定的个性心理品质上来研究，是符合马克思主义关于人的学说和现代教育心理学理论以及初中化学教学实际的；初中生学习化学兴趣的形成和发展是一个立体发生的过程，其纵向趋势为：直感兴趣→解析兴趣→探索兴趣；其横向品质为：指向性、持久性、广泛性和有效性，初中生学习化学兴趣水平的提高应当在有效的教学中进行

Cyclosporine is angiostatic

The systemic effect of the immunosuppressive drug cyclosporine (CS) on formation of new blood vessels was studied quantitatively in rats using the mesenteric-window assay. Angiogenesis was induced by i.p. injection of saline. CS at a s.c. dose of 4 mg/kg/day, which is in the range used clinically, suppressed angiogenesis (inhibiting branching or tortuosity more than spatial expansion), and appeared to be non-toxic. This is the first report on an apparently selective angiostatic effect of CS. The finding is likely to have implications for the clinical use of CS, not only in certain types of organ transplantation but possibly also in psoriasis and other angiogenesis-dependent diseases.     

Pathways for oxidative fuel provision to working muscles: Ecological consequences of maximal supply limitations

The study of metabolic fuel provision and its regulation has reached an exciting stage where specific molecular events can be correlated with parameters of the organism's ecology. This paper examines substrate supply pathways from storage sites to locomotory muscle mitochondria and discusses ecological implications of the limits for maximal flux through these pathways. The relative importance of the different oxidative fuels is shown to depend on aerobic capacity. Very aerobic, endurance-adapted animals such as long distance migrants favor the use of lipids and intramuscular fuels over carbohydrates and circulatory fuels. The hypothesis of functional co-adaptation between oxygen and metabolic fuel supply systems allows us to predict that the capacity of several biochemical processes should be scaled with maximal oxygen consumption. Key enzymes, transmembrane transporter proteins, glucose precursor supply and soluble fatty acid transport proteins must all be geared to support higher maximal glucose and fatty acid fluxes in aerobic than in sedentary species.     

Algorithmic compression of empirical data: reply to Twardy, Gardner, and Dowe

This discussion note responds to objections by Twardy, Gardner, and Dowe to my earlier claim that empirical data sets are algorithmically incompressible. Twardy, Gardner, and Dowe hold that many empirical data sets are compressible by Minimum Message Length technique and offer this as evidence that these data sets are algorithmically compressible. I reply that the compression achieved by Minimum Message Length technique is different from algorithmic compression. I conclude that Twardy, Gardner, and Dowe fail to establish that empirical data sets are algorithmically compressible.

Why the Afshar experiment does not refute complementarity

A modified version of Young's experiment by Shahriar Afshar demonstrates that, prior to what appears to be a “which-way” measurement, an interference pattern exists. Afshar has claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer's Transactional Interpretation easily accommodates the result. It is also shown that the Afshar experiment is analogous in key respects to a spin one-half particle prepared as “spin up along x”, subjected to a nondestructive confirmation of that preparation, and post-selected in a specific state of spin along z. The terminology “which-way” or “which-slit” is critiqued; it is argued that this usage by both Afshar and his critics is misleading and has contributed to confusion surrounding the interpretation of the experiment. Nevertheless, it is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and post-selection spin experiment, in which the particle's preparation state is confirmed by a nondestructive measurement prior to post-selection. In addition, some new inferences about the interpretation of delayed choice experiments are drawn from the analysis.
