Factors Associated with Having Flextime: A Focus on Married Workers

To examine flexible work scheduling of married workers a conceptual framework was developed and tested using the 1997 Current Population Survey Work Schedules Supplement. Odds of flextime use were higher for married males, non-Hispanic whites, those with relatively higher levels of education and income, those with a preschool aged child, residents of the Midwest or West (as compared with the South), managers or professionals, and employees of the federal government.     

Infants' Ability to Learn Phonetically Similar Words: Effects of Age and Vocabulary Size

What do novice word learners know about the sound of words? Word‐learning tasks suggest that young infants (14 months old) confuse similar‐sounding words, whereas mispronunciation detection tasks suggest that slightly older infants (18–24 months old) correctly distinguish similar words. Here we explore whether the difficulty at 14 months stems from infants' novice status as word learners or whether it is inherent in the task demands of learning new words. Results from 3 experiments support a developmental explanation. In Experiment 1, infants of 20 months learned to pair 2 phonetically similar words to 2 different objects under precisely the same conditions that infants of 14 months (Experiment 2) failed. In Experiment 3, infants of 17 months showed intermediate, but still successful, performance in the task. Vocabulary size predicted word‐learning performance, but only in the younger, less experienced word learners. The implications of these results for theories of word learning and lexical representation are discussed.     

Bilingual Education Models in Latvia: A view from Belarus

In this article, we look at several issues relating to bilingual education in Latvia, as prescribed by the Latvian Ministry of Education and Science. We examine these issues from the perspective of the past and present situation in Belarus, Russia and the former Soviet Union. It is clear, in our view, that bilingual offers both advantages, but also various drawbacks if it is not implemented in an appropriate way. This applies to both the societal and the personal (cognitive level). Movement towards the dominant languages (in this case Latvian) needs to be viewed as a gradual process. Although each generation of newcomers might start with a passive knowledge of the dominant (second) language, this changes into a fluent grasp of the second language across generations. The original native language will lose its dominance in this process.

Trauma Events, Residence in Refugee Camps, and Educational Attainment as Predictors of Trauma Symptoms of Albanian Refugees in Macedonia

Adult members of 79 Albanian families who had fled from Kosovo to Macedonia during the immediate postwar period (June–August 1999) were interviewed. In conjunction with therapeutic intervention, the Harvard Trauma Questionnaire (HTQ) and the General Health Questionnaire (GTQ) were administered. Trauma symptoms as measured by the HTQ and psychological distress as measured by the GHQ were highly correlated. The best predictor of psychological distress was severity of the trauma experienced. Refugees with high educational attainment had fewer trauma symptoms than those with lower educational attainment. Refugees who lived with host families in towns showed fewer trauma symptoms than those who lived in camps, but they were also more highly educated. The results of hierarchical multiple regression analyses suggested that educational attainment may mediate the effect of place of residence. Educational attainment may be an indicator of resourceful and effective coping strategies that ameliorate the effects of trauma.

历史教学中的思想政治教育失落与重建

升学主义的误导以及忽视学生思维独立性与批判性的填充式教学,造成了历史教学中思想政治教育的失落困境,其重建任重道远。订立明确、具体、简洁的思想教育目标应该先行,再运用情理合一、悬念例证、逆向思维、引发争议、对症下药、浅者深掘等渗透教育手段、创造有利于思想政治教育的民主课堂。
