The development and maturation of humanitarian psychology.

Humanitarian psychological support as an organized field is relatively young. Pioneers in the field were involved primarily in providing psychological support to refugees and internally displaced persons in conflict and nonconflict situations. This article describes basic principles for the design of psychological support programs and interventions. The International Federation of Red Cross and Red Crescent Societies (IFRC) began a psychological support program in 1991. The IFRC chose psychological first aid as its model for implementation in developing countries. Psychological first aid fits all the principles for psychological support program design and is adapted to individual communities. The first generation of psychological support programs differed dramatically depending on the countries in which they were developed. A second generation of psychological support programs evolved in response to the earthquake/tsunami of December 26, 2004. The Inter-Agency Standing Committee international guidelines consolidated the advances of second-generation programs and provided a clear indication of the wide acceptance of the importance of psychological support. A glimpse is provided of the third generation of psychological support programs, and an admonition is made for a more empirical evaluation of the effectiveness of interventions.

Relationships between identity formation and computer use among black and white emerging adult females

The purpose of this study was to examine the relationships between computer use, identity formation, and self-esteem among Black and White emerging adult females. One hundred 56 female college students participated in this study by completing a survey that included the Internet/Computer Use Questionnaire, the Ego Identity Process Questionnaire, and the Rosenberg Self Esteem Scale. Racial differences were found between Black and White females with regard to perceived problematic use of the Internet and use of the computer for communication and use of the Internet for schoolwork. In addition, differences between Black and White females were found between identity formation and problematic use of the Internet and between self-esteem and type of use of the Internet. These findings were discussed in relation to future research and interventions.

丁烷脱沥青装置掺炼油浆工艺

由于新疆原油的渣油中重金属含量高，结构组成复杂，直接进入催化裂化装置做原料时，催化剂重金属污染严重，产品分布差，渣油掺炼量低。而且，丁烷脱沥青过程所得到的脱油沥青软化点高、针入度低、延伸度差。为了提供优质的催化裂化原料和优质的道路沥青原料，进行了丁烷脱沥青装置掺炼油浆组合工艺的开发和应用，取得了较好的效果，脱沥青油收率提高，提供了更多重金属含量低的催化裂化原料，沥青性能得到改善。
