The Gendered Politics of Public Health: Jewish Nurses and the American Joint Distribution Committee in Interwar Poland

This article examines the gendered politics of public health initiatives among Jews in interwar Poland by focusing on the establishment and activity of the Warsaw School of Nursing (Szko?a Piel?gniarstwa przy Szypitalu Starozakonnych w Warszawie). Founded in 1923 and funded by the American Jewish Joint Distribution Committee, the school’s staff believed that they could shape the attitudes and behaviors of Polish Jewish women and use them as a conduit to advance their vision for a Polish state committed to the protection of Jews and their equality before the law. Drawing upon the voices of JDC officials, local Jewish health activists, Polish government officials, and young Jewish women in the Second Polish Republic, the article highlights the multiple and frequently conflicting ways in which gender figured in their political imagination. It also sheds light on the efforts of American Jewish humanitarian activists and Polish Jewish women alike—much like their counterparts throughout Europe and North America—to reframe traditional gendered expectations for women in order to expand their range of professional choices and the roles they could play in public life. The final section of this article recounts the school’s decline and compares its fate to a Jewish nursing school initiative in the city of Vilna. In doing so, it assesses the limits of the Joint Distribution Committee’s interethnic bridge-building initiatives in interwar Poland.     

Healthy Lifestyle,Well-being,Physical Activity,Sport, and Scholastic/academic Performance: Interactions and Connections

The physical activity and sport are key elements for a healthy lifestyle. However, a little-investigated element is the presence of a possible relationship between school or academic performance and the participation in physical activity and sport in groups of preadolescents and adolescents. In order to clarify the complex relationship between mind and body in preadolescence and adolescence, the present discussion investigates the causal and direct relationship between sport activity and performance; and describes how this relationship can be mediated by the sense of self-esteem and self-efficacy; and investigates the relationship between group sports practice and school or academic performance.     

The detection of a tone added to a narrow band of noise: The energy model revisited

In an effort to determine whether cues related to changes in energy contribute to the detection of a tone added to a narrow band of noise, we examined the effect of level variation on detection thresholds. In the first experiment, the level of each waveform was randomly varied on each presentation. Level variation had only marginal effects on performance. In addition, detection thresholds were obtained using bands of noise with equal energy across intervals. Neither increasing nor decreasing the variance of the noise-alone and tone-plus-noise energy difference distributions altered the detectability of a tone added to noise. Thus, the changes in energy that are concomitant with the addition of the tone are not the sole cue for the detection of the tone. In a second experiment, three psychometric functions were measured. One function was determined using no level variation, one was measured in the presence of level variation, and one was measured in the context of level variation, but for trials without level variation. The context of level variation slightly reduced detectability. In a third experiment, we compared detectability in three conditions: no level variation, across-trial level variation, and across-interval level variation. The thresholds obtained in the absence of level variation were superior to those measured in the presence of level variation, regardless of the manner in which the level variation was incorporated.
