Teacher workshops chip away at economic illiteracy
Workshops put on for teachers by the Atlanta and St. Louis Feds are having the desired results, a recent assessment shows. Teachers are learning about the economy and personal finance, and they are passing this information on to a student body that desperately needs it.Education - Economic aspects ; Economics - Study and teaching
Cultural Influences on Women in Leadership: An Extension of the Hofstede and GLOBE Dimensions
Technology has forever changed the face of business. Although in the past business markets have been limited to local geographic areas, the concept of outsourcing has opened a diverse spectrum of international markets. An increase in suppliers and consumers can improve business effectiveness and efficiency, but entering international markets can be detrimental if the business is unaware of the subtle differences the new market has in regard to leadership styles and cultural values. Hofstede\u27s cultural dimension analysis has been the primary research study for many industry and academic professionals (Bond 2002; Hofstede 1997). However, many scholars are questioning whether Hofstede\u27s work is still relevant in the fast-changing business world, especially with the influx of women in the workforce. This proposal combines the research presented by Hofstede and the GLOBE study and narrows in on the effects culture has on women pursing leadership, particularly women already labeled as leaders. Seventy-two women from thirty-one different countries attending the 2014 Insight Dubai Conference were surveyed
Brugia Pahangi: Effects of Maternal Filariasis on the Responses of Their Progeny to Homologous Infection.
The effects of in utero and neonatal exposure to maternal Brugia pahangi infections on the development of homologous infections, immune responses, and pathologic lesions was studied in age-matched progeny of infected and uninfected female jirds. High IgG antibody titers to B. pahangi antigens were present in the sera of progeny from infected mothers. These neonatal titers to homologous antigens were shown to be of maternal origin, and did not alter the cellular responses of uninfected progeny as measured by in vitro antigen-stimulated blastogenesis and in vivo pulmonary granulomatous inflammatory responses to antigen-coated beads. Studies were conducted to measure age-related differences in susceptibility, lymphatic lesion formation, and antibody responses to B. pahangi infection in 2, 6, 10, and 15-week old jirds from uninfected mothers. Significant reductions in quantities of testicular and intralymphatic worms recovered and antibody responses to solbule antigens in jirds infected at 2 weeks of age had no measurable effect on susceptibility or lymphatic lesion severity expressed as the ratio of intralymphatic thrombi formed per intralymphatic worm. Challenge infections in 2- or 4-week old progeny from B. pahangi-infected and uninfected female jirds yielded equivalent adult worm recoveries and microfilaremias. Lymphatic lesion severity expressed as the ratio of intralymphatic thrombi formed per intralymphatic worm recovered was similar in all groups. Offspring infected at either 2 or 4 weeks of age from infected mothers exhibited significantly lower serum IgG antibody titers to B. pahangi antigens compared to infected progeny of uninfected mothers at 5-8 weeks postinfection. Infected offspring from infected mothers displayed significantly fewer antigen-specific splenic plague-forming cells at 5 weeks postinfection than infected control progeny. Qualitative and quantitative reductions in serum antibody reactivity to B. pahangi antigens were also demonstrated by Western immunoblot at 8 weeks postinfection in infected progeny of infected females. These results suggest that a partial immune tolerance to B. pahangi antigens develops in infected offspring of infected female jirds. These modulated antibody responses had no measurable effect on the establishment of adult worms, microfilaremias, lymphatic lesion development, or antigen-specific pulmonary granulomatous inflammatory responses
Being Authentic in Life and on Stage: A Phenomenological Investigation of the Actor as Character
The purpose of this study is to describe the process of character development as experienced by the actor. Twelve professional actors participated in 60 to 90 minute phenomenological interviews in which they were asked to talk about their experiences of character development. Each participant was asked to respond to the following statement, \u27\u27Take a moment to think about a specific character you played. Please describe for me in as much detail as you can what stood out for you during the development of that character.
Interviews were audiotaped and transcribed. The transcripts were analyzed individually and in a group format using an existential/phenomenological method. Data analysis revealed a thematic structure comprised of five themes: (a) Preparation, (b) Use of Self, (c) Connection, (d) Being in the Moment, and (e) Personal Gain. Analysis also revealed that the five figural themes were contextualized within the frame of one experiential ground: Authenticity. In other words, this ground provides the primary context through which the themes of the experience of character development become figural. Participants\u27 descriptions of their experiences were always situated within the context of being authentic to all aspects of character development.
The first theme Preparation was comprised of three sub-themes: The Script, Research, and Meaning of the Text. The theme Use of Self was comprised of six subthemes: Association of Self with Character/Past Experiences, Own Emotions, Body/Embodiment, Intuition, Availability of Self, and Reciprocity of Two Worlds. The theme Connection was comprised of three sub-themes: Relating to the Character, Connection with Scene Partners, and Connection with the Director. The theme of Being in the Moment was comprised of two sub-themes: Being in the Zone and The Ultimate Goal. The last theme, Personal Gain was comprised of the following three sub-themes: Catharsis, Security, and Personal Transformation. Results are discussed in relation to existing literature. This was followed by implications for the fields of psychology and theatre and suggestions for further research
Sequence of protein expression of bone sialoprotein and osteopontin at the developing interface between repair cementum and dentin in human deciduous teeth
Experimental periodontal regeneration studies have revealed the weak binding of repair cementum to the root surface, whereas attachment of cementum to dentin preconditioned by odontoclasts appears to be superior. The aim of this study has been, therefore, to analyze the structural and partial biochemical nature of the interface that develops between resorbed dentin and repair cementum by using human deciduous teeth as a model. Aldehyde-fixed and decalcified tooth samples were embedded in acrylic or epoxy resins and sectioned for light and transmission electron microscopy. Antibodies against bone sialoprotein (BSP) and osteopontin (OPN), two noncollagenous proteins accumulating at hard tissue interfaces in bone and teeth, were used for protein A-gold immunocytochemistry. Light microscopy revealed a gradually increasing staining intensity of the external dentin matrix starting after the withdrawal of the odontoclast. Labeling for both BSP and OPN was first detected among the exposed collagen fibrils and in the intratubular dentin matrix when odontoclasts had withdrawn but mesenchymal cells were present. Subsequently, collagen fibrils of the repair cementum were deposited concomitantly with the appearance of labeling for BSP and OPN over the intratubular, intertubular, and peritubular dentin matrix. Labeled mineralization foci indicated the advancing mineralization front, and the collagenous repair matrix became integrated in an electron-dense organic material that showed labeling for BSP and OPN. Thus, no distinct planar interfacial matrix layer lies between the resorbed dentin and the repair cementum. The results suggest that odontoclasts precondition the dentin matrix such that the repair cementum becomes firmly attache

Liquid Chromatographic Resolution and Bioassay of Napropamide Herbicide Enantiomers
The enantiomers of the herbicide napropamide (1) were separated on a ?g-scale using chiral liquid chromatography and submitted to a bioassay for herbicidal activity using a wheat germ test. Under these conditions, only one enantiomer showed herbicidal activity. The potential
for reducing the application rate of pesticides by omitting isomeric ballast is discussed
