Two hundred twenty-four undergraduate students wrote about one-half of an inning of a baseball game and about one-half of a soccer game, counterbalanced, for 20 min each. Students then completed two six-item interest inventories—one each on the topics of baseball and soccer—and tests of baseball knowledge and soccer knowledge. Hierarchical regression analyses revealed that individual interest in baseball was significantly related to the proportions of game actions and irrelevant-nongame actions, controlling for gender, discourse knowledge, and topic knowledge. Topic knowledge was significantly related to thematic maturity, controlling for gender and discourse knowledge. Students wrote more topic-relevant information on the baseball story—a relatively high-interest topic—than on the soccer story, a relatively low-interest topic. Implications for the Flower and Hayes (1981) writing model and for assigning students writing topics are discussed.  相似文献

University students and instructors constantly correlate their personal interests with generally accepted interests and corporate norms. The process of assimilating organizational norms is not always characterized by the optimum dynamics and focus among all the students and even instructors. Students’ and instructors’ personal interests often do not coincide with corporate norms of a higher educational institution. This fact sometimes has an ambiguous influence on their self-fulfillment, ethical, moral values and professional development. Non-institutional character of some personal interests often generates a mistaken opinion that as a result of long studies or work at university a person fully assimilates the values and ethical behavioral norms stipulated in basic corporate acts of the organization. The resolution of a conflict between personal and public interests is one of the main ways to perform the integration of interests.  相似文献

We study smoking-cessation apps in order to formulate a framework for ethical evaluation, analyzing apps as ‘medium’, ‘market’, and ‘genre’. We center on the value of user autonomy through truthfulness and self-understanding. Smoking-cessation apps usually communicate in an anonymous ‘app voice’, with little presence of professional or other identified voices. Because of the fast-and-frugal communication, truthfulness is problematic. Messages in the ‘quantification’ modules may be read as deceitfully accurate. The app voice frames smoking as a useless, damaging habit indicative of weakness of will, in a ‘cold-turkey’ frame of individual mind-over-body heroism. Thus apps contribute to a stigmatization of smokers and culpabilization of relapses. The potential to support user autonomy through diverse meaningful voices and personalized communication remains yet unused.  相似文献

Conidial fungi or molds and mildews are widely used in modern biotechnology as producers of antibiotics and other secondary metabolites,industrially important enzymes,chemicals and food.They are also important pathogens of animals including humans and agricultural crops.These various applications and extremely versatile natural phenotypes have led to the constantly growing list of complete genomes which are now available.Functional genomics and proteomics widely exploit the genomic information to study the ...  相似文献

In this study, the dyes present in five 17th- to 18th-century textiles from the National Museum of Art of Romania, three religious embroideries and two brocaded velvets, are characterized and discussed, together with earlier results on textiles from Romanian collections obtained by the same research group. Dye analyses were performed using two methods: the well-established liquid chromatography-diode array detection (LC–DAD) and a recently developed liquid chromatography-mass spectrometry (LC–MS) analytical protocol. The examination of very small historical samples by both techniques allows a better insight in the advantages and limitations of the two approaches to real analyses to be obtained. LC–MS data interpretation is based entirely on the results accumulated for dye standards. Electrospray ionization (ESI) was used in the negative ion mode and an ion trap served as mass analyzer. Both single stage (MS) and tandem (MS/MS) mass spectrometric approaches were considered. The dyes and natural sources identified by both analytical techniques are discussed in the historical context of the textiles, with respect to earlier results collected for similar Romanian objects. The study showed that the dye sources found in the 17th- and 18th-century Romanian velvets and embroideries were produced using a wide variety of dye sources, suggesting influences from Europe as well as from Asia Minor. Dye sources imported from New World have been also detected. The range of biological sources is in very good correspondence with earlier results obtained from textiles in the Romanian Collections. LC-MS (single stage and tandem MS) approaches have been demonstrated to be valuable tools for dye identification in small-scaled samples from historical textile objects only if sufficient knowledge on the dyes and their biological sources is first accumulated within experiments performed on standard dyes and standard dyed fibers.  相似文献
