提高粉煤灰低密度水泥体系早期强度的研究

针对粉煤灰低密度混合材水泥的早强问题展开研究,用实验方法分析探讨了粉煤灰低密度混合材水泥在水化反应过程中的作用机理,开发出了一种高效的能够适用于低温低密度体系的早强剂DY,使得粉煤灰低密度水泥早期强度得到显著的提高。粉煤灰混合材低密度水泥在低温下早期强度的提高,主要通过水泥与粉煤灰之间的相互作用来实现。正反两方面的实验结果表明,水化反应使早期释放更多的Ca²⁺和OH^-,引发了粉煤灰的火山灰反应,从而促进了粉煤灰混合材水泥早期强度的发展。该产品有望在低压井、易漏井、长封固段井等复杂条件下使用。粉煤灰混合材水泥能够满足复杂井固井作业的要求,并且具有可观的经济、环保效益。     

Psychological Treatment of Slot-Machine Pathological Gambling: New Perspectives

In this paper the most relevant findings of our research team on pathological gambling in the last decade are presented. There is no conclusive empirical evidence of a specific profile of the pathological gamblers. The choice treatment appears to be stimulus control and in vivo exposure with response prevention, followed by a cognitive-behavioral intervention in relapse prevention. Predictive variables for the therapeutic failure were the dissatisfaction with the treatment, the alcohol abuse and the neuroticism as a personality variable. Unanswered questions for future research in this field are commented upon.     

新时代高校招生就业工作的实践路径探析以——西南石油大学为例

党的十九大为党和国家各项事业发展提供了理论指南和行动纲领,也为高校招生就业创新发展提供了新的理论指导。在高校招生就业工作中贯彻落实党的十九大精神,需要明晰历史变革、理论创新、事业发展三个维度下高校招生就业条件的变化,以进一步明确新时代高校招生就业的历史方位;需要厘清高校招生就业反映出来的根本问题、重点问题、主要问题、基本问题,不断认清新时代高校招生就业面临的时代问题。在新时代背景下,坚持以习近平新时代中国特色社会主义思想为指导,融合高校思想政治教育发展,丰富多学科视角下的理论体系,推动新理念新技术应用,激活工作端口的延伸性,提升打造工作队伍,是当前高校招生就业改革和发展的重要路径。

贫困地区农村文化建设的居民满意度及提升对策探讨——基于重庆市的调查研究

以重庆市3个国家级贫困县万州区、奉节县和巫溪县的农村居民为主要研究对象，采用问卷法和访谈法调查贫困地区农村居民对当前文化建设的满意度及其未来需求状况。研究发现，当前贫困地区农村文化建设处于起步阶段，多元供给机制尚未形成，农村居民对当前文化建设整体满意度较低，尤其是公共文化设施满意度最弱；然而农村居民对未来文化建设的整体需求不足，公共文化服务呈现出明显的低满足、低需求的“双低状态”。对此，本文认为贫困地区农村文化脱贫要以居民精神脱贫为基础，引导居民文化需求层次，辅以差异化供给、多元供给、培养文化建设自生动力，以提升贫困地区农村居民文化建设满意度，满足居民未来文化需求。     

“中国档案分类法”与“中国图书馆分类法”辅助符号之比较

档案分类同图书分类一样,都要用到各种辅助符号,以确保类目的指向更加准确.“中国档案分类法”和“中国图书馆分类法”都采用了10余种辅助符号,两种分类法的辅助符号之间,既有联系,又有区别

An exploratory study on the conditions of health, safety and environmental affairs of very small and small-size enterprises in Brazil

This paper focuses on the reality of very small and small enterprises (VSSEs) in Brazil, concerning health and safety management of their workers. These companies tend to operate in a few administrative levels. The owners' health and safety culture is fundamental for the implementation of preventive measures. The VSSEs end up adopting merely reactive and under-the-law actions. In order to understand such reality, a questionnaire was elaborated especially for the research made. Fifty-five very small and small enterprises of the industrial, commercial and service sectors were selected. The research confirmed the reactive attitude shown by the VSSEs, thus demonstrating that none of the companies involved presented policies of safety and health. Even though not holding policies, programs or scopes of their activities, 22% of them revealed to have a clear definition of the responsibilities of their high level administration. Nevertheless, 10% had financial resources allocated to this sector. Such companies do not count on a frequent safety and health support. The ignorance on it leads them to take a reactive action. This study reaches its objective on contributing to the debate, besides indicating that the way to improvement is on the strict cooperation between governments, companies, workers and society.     

Software development for the evaluation of the ergonomic compatibility on the selection of advanced manufacturing technology

Advanced Manufacturing Technology (AMT) is one of the most relevant resources that companies have to achieve competitiveness and best performance. The selection of AMT is a complex problem which involves significant amount of information and uncertainty when multiple aspects must be taken into consideration. Actual models for the selection of AMT are found scarce of the Human Factors and Ergonomics perspective which can lead to a more complete and reliable decision. This paper presents the development of software that enhances the application of an Ergonomic Compatibility Evaluation Model that supports decision making processes taking into consideration ergonomic attributes of designs. Ergonomic Compatibility is a construct used in this model and it is mainly based in the concept of human-artifact compatibility on human compatible systems. Also, an Axiomatic Design approach by the use of the Information Axiom was evolved under a fuzzy environment to obtain the Ergonomic Incompatibility Content. The extension of this axiom for the evaluation of ergonomic compatibility requirements was the theoretical framework of this research. An incremental methodology of four stages was used to design and develop the software that enables to compare AMT alternatives by the evaluation of Ergonomic Compatibility Attributes.
