Cognitions,Emotions, and Applications: Participants' Experiences of Learning about Strengths in an Academic Library

This study examined academic library employees' experiences during “strengths education,” a process of learning about individual strengths during a positive psychology intervention. Participants took the Clifton StrengthsFinder test, attended a workshop, and then were interviewed about what they considered to be the effects of the strengths training. The focus of the qualitative analysis was the interviewees' statements about the intrapersonal and interpersonal effects of learning about their strengths. We categorized and coded these statements as cognitions formed, emotions experienced, and applications envisioned. Our findings raise interesting implications for job satisfaction and employee self-esteem, especially during times of change.

Maintaining Relationship Alternatives Electronically: Positive Relationship Maintenance in Back Burner Relationships

Back burners are desired prospective romantic/sexual partners that people communicate with to establish a future romantic or sexual relationship. We surveyed 658 college students about the extent to which they reported using various positive relationship maintenance strategies (positivity, openness, assurances) during communication with their most important back burner. Consistent with previous research, singles did not differ from those in committed romances in the number of back burners reported; however, singles and casual daters utilized the positive maintenance strategies to a greater extent than did those in committed relationships. Men reported using more assurances than did women, but the sexes did not differ on the other strategies utilized. Implications and limitations are discussed.     

“出”“入”之间见真情——试论谢灵运和杜甫山水诗之境界

谢灵运以他的学识和才气成为山水诗的开山鼻祖,此后山水诗到唐代达到了高峰,出现了以王孟为代表的清丽冲淡的派,并成为主流,杜甫一生的主要成就虽然不在山水诗,但他呕心写就的数百篇山水诗依然给我们提供了一个透视其心灵的途径。本文试从两者的创作背景和作品本身来探讨他们的相同点:对理想的执着。     

Students’ Discrete Emotional Responses in the Classroom: Unraveling Relationships With Interest and Engagement

Recent instructional communication research reveals that the communication and emotional processes at play in the classroom can influence class-specific emotions experienced by students. Students’ enjoyment and pride were positively related to their emotional interest, while students’ enjoyment, hope, and pride were positively associated with their cognitive interest. While students’ anger and boredom were inversely related to their emotional interest, students who reported greater hopelessness and anger indicated decreases in cognitive interest. Students’ hope and pride were positively associated with their overall engagement behaviors. Anger, anxiety, shame, and boredom led students to report decreases in their engagement. Follow-up tests highlighted challenges in the assessment of specific emotional responses; exploratory factor analysis simplified the measurement of these variables and provided additional insight into expected relationships.
