Tactual perception of embossed Morse code and braille: the alliance of vision and touch

In three experiments observers made visual matches to tangible embossed patterns. Stained glass was used to blur vision and thus allow the effect of visual guidance of tactual exploration on the accuracy of symbol recognition to be evaluated. Stained glass rendered the embossed code invisible, but allowed sight of the hand. In the first experiment subjects identified patterns made up of dots and dashes drawn from Morse code; in the second and third experiments they studied braille. The results show that subjects are more accurate in 'reading' tangible codes when provided with visual guidance. Performance was higher for braille than for Morse code. Vision aided touch through the provision of a frame of reference and through sight of scanning movements. Naive sighted observers were able to identify invisible braille dots by watching other individuals touch the symbols, suggesting the importance of vision of kinesthetic patterns.     

Objects, raised lines, and the haptic horizontal-vertical illusion

Experiments were conducted to determine whether the haptic horizontal-vertical illusion occurs with solid, three-dimensional objects as well as with tangible lines. The objects consisted of round or square bases, with dowel rods projecting above them at heights equal to the widths of the horizontal bases. A negative illusion, with overestimation of horizontals, was found with free haptic exploration, but not with tracing with the fingertip. The negative illusion occurred when subjects felt wooden Ls and inverted Ts with a grasping, pincers motion of the index finger and thumb. The presence or absence of illusory misperception was dependent upon exploration strategy, since the negative illusion vanished with finger tracing. A negative illusion was also found when subjects adjusted a vertical dowel so that it was judged to be equal in extent to a round or square base. A general overestimation of judged size derived from the pincers response measure, but was not found with the use of a tangible ruler. Comparable illusory results are most likely when drawings and objects promote similar haptic scanning methods. The results were consistent with the idea that the orientation of an edge or line is more important than whether one explores a tangible line or a three-dimensional object.     

The Dispositional Sources of Job Satisfaction: A Comparative Test

This study related three personality taxonomies—positive affectivity and negative affectivity (PA and NA), the five-factor model (the "Big Five"), and core self-evaluations—to job satisfaction in an integrative test. In a longitudinal design with multi-source data, results indicated that the traits from all three taxonomies generally were significantly related to job satisfaction, even when the traits and job satisfaction were measured with independent sources. However, when all three typologies were examined concurrently, the core self-evaluations typology was the only typology that was significantly related to job satisfaction. The study extends research on the validation of these frameworks by assessing convergent and discriminant validity issues, and shows that core self-evaluations adds to our understanding of the dispositional source of job satisfaction.     

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.
