This study is the first to inquire about the factors that influence people’s willingness to allow professional photojournalists to tell their stories through the medium of the photo essay. Guided by Self-Disclosure Theory, in-depth interviews were conducted with the subjects of 15 peer-judged award-winning photo essays. These were drawn from the multiple picture categories of the National Press Photographers Association (NPPA) Monthly Clip Contest, the annual NPPA Best of Photojournalism Contest, and the annual World Press Photo Contest between 2013 and 2017. The topics of the photo essays were sensitive in nature. Analysis reveals support and appreciation amongst photo-essay subjects for the profession of photojournalism. Motivations derived from the sensitivity and professionalism with which each interviewee was initially approached, a need to tell a different side of the story, a desire to inspire others or invoke change, and the memory-keeping and permanence afforded through published professional photojournalism. 相似文献

ABSTRACTThis article includes findings from a mixed method survey at a large, public midwestern university following the election of Donald J. Trump as the president of the United States. It examines student perceptions about effective engagement in political discourse within social work classes. Survey questions urged students to suggest how instructors might facilitate this dialogue fairly in the classroom given the passionate emotions and differing viewpoints surrounding the election, while acknowledging and educating about values espoused by the profession. Findings from this study illustrate the challenges that students face in having these conversations and outline their recommendations to social work educators for facilitating safe, sensitive, and inclusive classroom discussion about politics. 相似文献

Rubrics are increasingly used as tools to evaluate student work. This study examined BSW students' perceptions of the benefits and challenges of using rubrics. Pre- and posttest questionnaires were administered to 35 students in two sections of a diversity course. Students judged the use of rubrics favorably. Rubrics communicated the instructors' expectations, clarified how to write course assignments, explained grade and point deductions and, in general, made course expectations clearer. Students suggested that the rubric design should be self-explanatory and easy to follow. If carefully developed, rubrics may be a useful tool for advancing student learning in social work programs. 相似文献

Medicinal plants have been used by marginal communities to treat various ailments. However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants (Caralluma acutangula, Rhazya stricta, and Moringa peregrina) and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp. (6 isolates), Alternaria sp. (2), Bipolaris sp. (1), and Cladosporium sp. (1) based on 18S rDNA sequencing and phylogenetic analysis. The culture filtrates (CFs; 25%, 50%, and 100% concentrations) from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF (100%) of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry (GC/MS) analysis showed the highest indole acetic acid content ((54.31±0.21) μmol/L) in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses. 相似文献

We investigated the effect of UV-B irradiation on PI 3-kinase activity in human fetal hepatocytes. When cells were exposed
to monochromatic (304nm) UV-B light, a significant increase in intracellular PI 3-kinase activity was observed in a dose dependent
manner with maximal activity upon 1500 Jm−2 irradiation. At 1500 Jm−2 dose PI 3-kinse activity increased by 80% in membrane fraction of fetal hepatocytes of 25 weeks gestation. PI 3-kinse inhibitors
wortmannin and LY294002 specifically inhibited the UV-B induced lipid kinase activity and blocked significantly the UV-B induced
cell viability. The data suggests a correlation between cell survival and elevated levels of PI 3-kinase and suggest that
UV-B irradiation at a dose of 1500 Jm−2 is ideal for fetal hepatocyte transplantation. Also, PI 3-kinase levels could be a representative marker for viable UV-B
irradiated fetal hepatocytes for transplantation. 相似文献
