This paper investigates mobile phone use as a medium of inter‐generational communication. Research on teenage mobile phone use has tended to focus on its peer group functionality. In this paper, the mobile phone is examined as a transitional object in parent–teen interrelationships. Specifically, drawing on ethnographic work conducted in Israel among teenagers between 2000 and 2006, the paper focuses on mobile telephones as physical objects that can connect people and mediate relationships. It is shown that, for parents and their teenage children, the mobile phone is important more for the possibility of communication and less for the text or voice conversation it actually carries. Analysis focuses also on the role of the mobile phone in enabling inter‐generational distance and intimacy, attending to the complicated ways in which the mobile phone is employed by parents and their teenage children. It is argued that the analysis of mobile phone practices needs to take directly into account the specific cultural contexts of production and consumption, as culture, technology and family mutually shape one another.  相似文献

The relationship between hopelessness and depression in predicting suicide‐related outcomes varies based on the anticipation of positive versus negative events. In this prospective study of adolescents at elevated risk for suicide, we used two Beck Hopelessness Scale subscales to assess the impact of positive and negative expectations in predicting depression, suicidal ideation, and suicidal behavior over a 2‐ to 4‐year period. In multivariate regressions controlling for depression, suicidal ideation, and negative‐expectation hopelessness, positive‐expectation hopelessness was the only significant predictor of depressive symptoms and suicidal behavior. Clinical interventions may benefit from bolstering positive expectations and building optimism.  相似文献

Music and mathematics require abstract thinking and using symbolic notations. Controversy exists regarding transfer from musical training to math achievements. The current study examined the effect of two integrated intervention programs representing holistic versus acoustic approaches, on fraction knowledge. Three classes of fourth graders attended 12 lessons on fractions: One class attended the ‘MusiMath’ holistic program (n = 30) focusing on rhythm within the melody. Another class attended the ‘Academic Music’ acoustic program (Courey et al., Educ Stud Math 81:251, 2012) (n = 25) which uses rhythm only. The third class received regular fraction lessons (comparison group, n = 22). Students in both music programs learned to write musical notes and perform rhythmic patterns through clapping and drumming as part of their fraction lessons. They worked toward adding musical notes to produce a number (fraction), and created addition/subtraction problems with musical notes. The music programs used a 4/4 time signature with whole, half, quarter and eighth notes. In the math lessons, the students learned the analogy between musical durations and fractions, but also practiced fractions other than . Music and math were assessed before, immediately following, and 3‐ and 6‐months post‐intervention. Pre‐ to post‐intervention analyses indicated that only the ‘MusiMath’ group showed greater transfer to intervention‐trained and untrained fractions than the comparison group. The ‘Academic Music’ group showed a trend on trained fractions. Although both music groups outperformed the comparison group 3‐ and 6‐months post‐intervention on trained fractions, only the ‘MusiMath’ group demonstrated greater gains in untrained fractions. Gains were more evident in trained than in untrained fractions. A video abstract of this article can be viewed at https://youtu.be/uJ_KWWDO624  相似文献

ABSTRACT

“Permission” and “prohibition” are key terms in Jewish religious discourse. For generations they have dominated as part of the primarily male, rabbinic discourse in talmudic literature. This paper will show that men no longer hold the monopoly on these terms because contemporary Israeli ultra-Orthodox women include them in their daily conversation in multiple and varied ways. The study examines exposure patterns and perceptions of 42 ultra-Orthodox women toward sectarian and general mass media. In responses to detailed questionnaires, the words “prohibited,” “forbidden” and “a boundary” constantly recur along with a variety of negatives, such as “not permitted,” “not allowed” and “not kosher”.

This paper argues that in describing their uses of and perceptions toward mass media, ultra-Orthodox women have adopted terminology borrowed from what was previously a primarily male-dominated conversation. Some might argue that these women are simply working within the bounds of ultra-Orthodox law which they accept as universally applicable; or perhaps that these women are simply reflecting words used by their husbands or rabbis. However, this study argues that their adoption of these terms indicates they are exercising their own agency. With a combined religious and secular education, and work that is primarily outside the house, many of them are the principal breadwinners in their homes. I suggest that this discourse is a part of their highly intelligent navigation of their simultaneous roles as both gatekeepers and change agents.  相似文献
