A person-centered approach to achievement goal orientations in competitive tennis players: Associations with motivation and mental toughness

Background:Research on achievement goal orientations in sport has typically relied on the use of variable-centered approaches that tend to overlook population heterogeneity.In this study,we used a person-centered approach to identify subgroups of competitive tennis players according to unique combinations of achievement goal orientations and tested for subgroup differences in motivation and mental toughness.Methods:A sample of 323 competitive tennis athletes(69.35%male)between 15 and 25 years of age(17.60±2.40 years,mean±SD)completed the 3×2 Achievement Goal Questionnaire for Sport,Sport Motivation Scale Ⅱ,and Mental Toughness Index.Latent profile analysis was used to identify unique combinations of achievement goal orientations.Comparisons between latent subgroups on autonomous motivation,controlled motivation,and mental toughness were performed using analysis of variance.Results:Latent profile analysis supported 3 distinct patterns of achievement goal profiles that were primarily distinguishable based on valence of competence(i.e.,approach vs.avoidance).Analyses of variance indicated that athletes who were classified into subgroups that endorsed approach types of goals(regardless of the types of avoidance goals they endorsed)reported higher levels of autonomous motivation and mental toughness.Conclusion:Results indicated that athletes tend to pursue a number of achievement goals collectively rather than in isolation.Although approach goals are more commonly linked to adaptive psychological functioning and positive outcomes,avoidance goals may also be associated with desirable psychological characteristics if they are pursued in conjunction with approach types of achievement goals.

Research and Practice on the Multi-dimensional Course Goal Achievement Evaluation of Software Engineering

According to the standards of engineering education accreditation,the achievement paths and evaluation criteria of course goals are presented,aimed at the objectives of software engineering courses and the characteristics of hybrid teaching in Kunming University of Science and Technology.Then a multi-dimensional evaluation system for course goal achievement of software engineering is proposed.The practice’s results show that the multi-dimensional course goal achievement evaluation is helpful to the continuous improvement of course teaching,which can effectively support the evaluation of graduation outcomes.

Achievements and Goals of China's Satellite Oceanic Remote Sensing

This paper is divided into three parts.In the first part,it describes the major objects of o-cean monitoring and investigation by means of satellite remote sensing technology,including the observation of dynamic phenomena of ocean,ocean color and sea surface temperature as well as mapping of coastal zone and islands.In the second part,some research results of oceanic environment which were obtained in the past decade in China are presented.In the third part,some fundamental technologies are described,to which we should pay attention in order to make great contribution to marine environment by using satellite remote sensing technology in the coming few years in China.

Goals Set for Initial Stage of the KIP Achieved

In a bid to establish a strong scientific and technological (S&T) innovation base in China, the State S&T leading group, the top government organ for S&T issues, gave the go-ahead, on June 6,1998, for the Chinese Academy of Sciences (CAS) to introduce a pilot project for the national knowledge innovation program (KIP). The objective of the pilot project is to re-structure the Academy into three major bases:
