обучение активным продажам в кризисе Иосифа ХусенскогоХусенский Иосиф
До кризиса, чаще работали на взаимном доверии, без предоплаты и многие получившие товар в прошлые докризисные месяцы, уже физически, исчезли с рынка, хотя об этом пока не говорят своим кредиторам. Чтобы не спугнуть своих многочисленных должников. Т.е. в такой ситуации никакие знания и опыт менеджеру продаж уже не помогут. Единственное, что большой опыт менеджера может позволить ему не тратить время и силы там, где клиент скрывает, что он «покойник» по факту и направить все силы на перспективных покупателей..

The document discusses several mathematical models and algorithms used in internet information retrieval and search engines:
1. Markov chain methods can be used to model a user's web surfing behavior and page visit transitions.
2. BrowseRank models user browsing as a Markov process to calculate page importance based on observed user behavior rather than artificial assumptions.
3. Learning to rank problems in information retrieval can be framed as a two-layer statistical learning problem where queries are the first layer and document relevance judgments are the second layer.
4. Stability theory can provide generalization bounds for learning to rank algorithms under this two-layer framework. Modifying algorithms like SVM and Boosting to have query-level stability improves performance.

On Mathematics Learning Perspective Among Teachers And Students In ChinaXu jiakon
The document discusses issues with mathematics education in China, including conceptions, teaching attitudes, and learning methodologies. It notes that mathematics is often viewed as a tool for selection and evaluation rather than being valued intrinsically. Students are focused on memorizing procedures rather than understanding concepts. The selection tradition in China dating back to imperial exams has alienated learning from its original purpose. Real changes may require redesigning the entire system rather than just adding new classes or programs.

Current projects consider more flexible curricula and connections between mathematics and computer science.
An Experimental Study On Students Higher Level Mathematics CognitionXu jiakon
This document summarizes an ongoing 3-year research project that aims to improve Chinese students' performance in higher-level mathematics cognition. Previous studies showed that while Chinese students performed better in lower levels like calculation and concepts, their performance did not improve in the highest level of analysis over 17 years. The research project uses quasi-experimental design and mathematics tasks requiring higher cognition to test improvements in students from grades 6 to 9. The goal is to find effective teaching methods to develop students' skills in the topmost level of mathematical thinking.
