电子商务企业竞争行为组合的选择与转换

以三家电子商务企业为研究对象,采用结构内容分析法,通过分析由权威电子商务研究网站和企业自身发布的234条竞争事件报道,研究电子商务企业竞争行为(市场与非市场行为)组合的选择和转换规律。结果表明:电子商务企业主要实施三种竞争行为组合:扩大范围型、提高地位型、获取资源型;战略目标与竞争行为组合之间存在匹配关系:经营范围战略与扩大范围型行为组合匹配;市场地位战略与提高地位型行为组合匹配;优势资源战略与获取资源型行为组合匹配;竞争行为组合转换的主要路径包括:扩大范围型——提高地位型或获取资源型、提高地位型——获取资源型、获取资源型——提高地位型;电子商务企业战略目标的改变导致了竞争行为组合的转换。     

Spontaneous Tumor Lysis Syndrome in an Infant: A Case Report

Tumor lysis syndrome has been observed in patients with malignancies with high cellular burden and high cell turnover, tumor sensitive to therapy, especially after initiating medical treatment. It very rarely occurs spontaneously. The case described here is of 6 months male infant who presented with fever since 1 month and loose stools associated with blood since 15 days. The laboratory investigations showed lactate dehydrogenase (LDH) of 6,192 IU/L and serum uric acid 18.2 mg/dl along with pancytopenia. The infant presented with electrolyte abnormalities and renal failure.     

Impact of age on haematological markers pre- and post-marathon running

This study investigated whether haematological markers differ between young and masters marathon participants, running at similar performance levels. Nine young (31.89 ± 4.96 years) and eight masters (63.13 ± 4.61 years) runners participated. At five time points (pre-race through 54 h post-race), a complete blood cell count, basic metabolic panel and creatine kinase (CK) isoenzyme panel were assessed. Race performance was standardised using the World Masters Association Age Grading Performance Tables. Total CK levels were elevated for all participants at all time points post-race (P < 0.001). The CK-isoenzyme MB% was elevated across groups at 6, 30 and 54 h post-race (P < 0.01, P < 0.01 and P < 0.05), with masters runners having a higher CK-MB% at 30 and 54 h (P < 0.05, P < 0.05). Total white blood cell and neutrophil counts were elevated through 6 h post-race (P < 0.001), with higher levels found in younger runners (P < 0.001). When considering all blood work, masters runners had a higher number of abnormal values at 6, 30 and 54 h post-race (P < 0.05, P < 0.01 and P < 0.05). In conclusion, masters runners demonstrated sustained CK-MB elevation, which may suggest greater cardiac stress. However, future studies using additional cardiac markers should be completed to confirm these findings. In addition, masters runners showed an increased number of laboratory values outside normal range, indicating the body’s reduced capacity to respond to marathon running.

从蓝棣之症候式分析看重写文学史中“人”的维度

在重写文学史中重新确立的新的文学规范,试图把过去作为政治依附品的文学解放出来,让文学成为具有其个性的独立个体。人作为其中重要的一环,人在文学作品评价中的"主体性"是一个十分重要的关键词,而蓝棣之的症候式批评方法,正是通过探析作者的深层精神世界,完成对作品的再评价,是在强调主体性前提下以一种极具个性眼光进行的一种重写文学史的实践。

面料二次设计的目的是提升服装及其所用面料的美学艺术效果,使其最大限度发挥服装附加值的功效。面料二次设计的表现技法主要有变形设计,破坏设计,附加设计,组合设计,钩、编织设计等。随着现代科技的发展,面料二次设计已逐渐成为服装设计转变的方向,它不仅符合服装时尚发展的要求,同时也是设计观念转变的体现,为设计师越来越个性化的追求提供了更为广阔的空间。     

Archipelagic rhetoric: remapping the Marianas and challenging militarization from “A Stirring Place”

Engaging critical rhetorical fieldwork in the Mariana Islands archipelago, this article destabilizes colonial naming projects and US federal control that dispossess island places from Indigenous peoples. On Euro-American and military maps, archipelagoes are depicted as distant, tiny, empty, or merely (is)lands for US geostrategic control. I argue for a remapping of the Marianas as expansive, oceanic sites of resistance to colonial cartographic violence and US militarization. Fieldwork in the Marianas demonstrates how Indigenous epistemologies function as archipelagic rhetoric enacted through a Chamoru sense of place. I examine these fluid relational connections to place and their implications for decolonization.     

Informational Sources,Social Media Use,and Race in the Flint,Michigan, Water Crisis

Safe, clean water is necessary for health and well-being. Water issues affect minority and vulnerable populations at disproportionate rates, including the poor and racial and ethnic minorities. An investigation of the relationships of race, social media use, and informational sources during the municipal water crisis in Flint, Michigan, reflects an instrumental view of communication and uses and gratifications theory in this study. Data from 208 Flint residents in 2016 indicated that African American respondents favored interpersonal networks and resources and were more likely than other racial groups to obtain current information about the water crisis via Instagram. Preferred channels and sources to receive additional crisis information varied on the basis of race.     

Framing Refuge: Media,Framing, and Sanctuary Cities

The refugee sanctuary movement in the United States has shifted to include undocumented immigrants fleeing violence and economic strife. Given the negative tenor of coverage of undocumented immigration, and ties between framing and policy views on immigration, how the media frames sanctuary cities is likely to impact public perceptions of these cities and their policies. To assess media coverage of sanctuary policies, we analyzed articles from five national newspapers from 1980 to 2017 with both human content analysis and dictionary-based computational analysis. We find that framing around religion/morality and conflict has decreased, while stories focusing on crime and partisanship have increased. We discuss implications for public opinion and the likelihood that the American public will take their cues from media framing and elite discourse when it comes to sanctuary policies.     

“大工程领域”人才培养模式探索与实践--以扬州大学化学工程领域多学科交叉人才培养为例

为了解决全日制工程硕士培养过程中知识面过窄、适应面单一的问题,适应未来工程人才“宽口径”培养的发展趋势,扬州大学秉承多学科交叉的教育理念,在化学工程领域进行了“大工程领域”全日制工程硕士培养模式的改革,并从人才培养定位、课程体系构建、课程设置、师资配备等方面开展了一系列的改革实践,其基本经验或许能为其它高校的全日制工程硕士人才培养改革提供有益的借鉴。
