Academic literature on the topic 'Jingfang, Hao'

Od lat 90. XX wieku w Chinach trwa złoty okres rodzimego science fiction, głównie dzięki temu, że stało się ono dla pisarzy środkiem do wyrażenia wszystkiego, czego nie była w stanie wyrazić literatura głównego nurtu, oraz komentowania nieustannie zmieniającej się teraźniejszości. W artykule zostaje przeanalizowany „Składający się Pekin” — opowiadanie przedstawicielki Nowego Pokolenia chińskiego science fiction, Hao Jingfang, które w 2016 r. zdobyło nagrodę Hugo. Wykreowany przy użyciu metod charakterystycznych dla science fiction oraz metaforyce przestrzeni obraz Pekinu z przyszłości jest refleksją nad problemami współczesności, takimi jak nieprzekraczalność barier społecznych, spetryfikowany system klasowo-warstwowy czy też rozwój technologiczny, który czyni ludzi zbędnymi. Opowiadanie może być odczytane jako utopijna przypowieść science fiction, która dzięki rozbudowanej metaforze rozwarstwionego społeczeństwa, uwięzionego w stanie nieustannej zmiany i bezosobowym mieście-molochu, ostrzega przed możliwą ponurą przyszłością, ale przede wszystkim wyraża zagubienie i niepewność współczesnego człowieka w obliczu ciągle zmieniającej się postmodernistycznej rzeczywistości i nowoczesnej technologii.

Odour is one of the main environmental concerns in the laying hen industry and may also influence animal health and production performance. Previous studies showed that odours from the laying hen body are primarily produced from the microbial fermentation (breakdown) of organic materials in the caecum, and different laying hen species may have different odour production potentials. This study was conducted to evaluate the emissions of two primary odorous gases, ammonia (NH3) and hydrogen sulphide (H2S), from six different laying hen species (Hyline, Lohmann, Nongda, Jingfen, Xinghua and Zhusi). An in vitro fermentation technique was adopted in this study, which has been reported to be an appropriate method for simulating gas production from the microbial fermentation of organic materials in the caecum. The results of this study show that Jingfen produced the greatest volume of gas after 12 h of fermentation (p < 0.05). Hyline had the highest, while Lohmann had the lowest, total NH3 emissions (p < 0.05). The total H2S emissions of Zhusi and Hyline were higher than those of Lohmann, Jingfen and Xinghua (p < 0.05), while Xinghua exhibited the lowest total H2S emissions (p < 0.05). Of the six laying hen species, Xinghua was identified as the best species because it produced the lowest total amount of NH3 + H2S (39.94 µg). The results for the biochemical indicators showed that the concentration of volatile fatty acids (VFAs) from Zhusi was higher than that for the other five species, while the pH in Zhusi was lower (p < 0.01), and the concentrations of ammonium nitrogen (NH4+), uric acid and urea in Xinghua were lower than those in the other species (p < 0.01). Hyline had the highest change in SO42− concentration during the fermentation processes (p < 0.05). In addition, the results of the correlation analysis suggested that NH3 emission is positively related to urease activities but is not significantly related to the ureC gene number. Furthermore, H2S emission was observed to be significantly related to the reduction of SO42− but showed no connection with the aprA gene number. Overall, our findings provide a reference for future feeding programmes attempting to reduce odour pollution in the laying hen industry.

Background. Complementary and alternative medicine (CAM) is widely applied in the clinical practice of neck pain owing to cervical radiculopathy (CR). While many systematic reviews exist in CAM to improve CR, research is distributed across population, intervention, comparison, and setting.Objective. This overview aims to summarize the characteristics and evaluate critically the evidence from systematic reviews.Methods. A comprehensive literature search was performed in the six databases without language restrictions on February 24, 2015. We had identified relevant systematic reviews that examined the subjects with neck pain due to cervical radiculopathy undergoing CAM. Two authors independently appraised the methodological quality using the revised assessment of multiple systematic reviews instrument.Results. We had included eight systematic reviews. The effectiveness and safety of acupotomy, acupuncture, Jingfukang granule, manual therapies, and cervical spine manipulation were investigated. Based on available evidence, the systematic reviews supported various forms of CAM for CR. Nevertheless, the methodological quality for most of systematic reviews was low or moderate. In addition, adverse reactions of primary studies were infrequent.Conclusions. Current systematic reviews showed potential advantages to CAM for CR. Due to the frequently poor methodological quality of primary studies, the conclusions should be treated with caution for clinical practice.

A Review of: Bhardwaj, R. K. (2014). Institutional repository literature: A bibliometric analysis. Science &Technology Libraries, 33(2), 185-202. http://dx.doi.org/10.1080/0194262X.2014.906018 Abstract Objective – Quantify the IR literature across the world by identifying countries with relatively high concentration of articles, describing the distribution of the literature by language, author (institutional and individual), journal, and examining characteristics such as the transformative activity index, and authorship and citation patterns. Design – This exploratory study of the literature used several bibliometric research methods to describe patterns and identify highly represented articles, authors, institutions, and journals. Setting – The Library and Information Science Abstracts database. Subjects – 436 articles from 118 journals. Methods – Research articles and review papers published through December 31, 2012, were identified by searching Library and Information Science Abstracts (LISA). Citation data for the 436 articles selected was gathered from LISA and Scopus. Main Results – The 436 articles from 118 journals had publication dates from 2001 through 2012, originated from 68 countries in 19 languages, and had authors affiliated with 159 institutions. The greatest number of institutional repository articles were published in 2011 while year-to-year growth was greatest from 2005-2006. Most highly represented were the United States and the United Kingdom, followed by India, Australia, and Spain. Twenty publishers were responsible for nearly half of the selected articles. The top four journals included OCLC Systems & Services, D-Lib Magazine, Serials Review, and Library Hi Tech. D-Lib Magazine alone published seven of the top 20 most cited articles. While most articles were written by a single author, the majority of the multiple author articles came from developed countries. Citation analysis reveals that the 436 articles were cited 2,071 times, for an average of 4.8 citations per article. However, 147 articles received no citations. The five most prolific authors were Elizabeth Yakel, Kim Jihyun, Karen Markey, Jingfeng Xia, and Sarika Sawant. Conclusion – The author concludes that developing countries lag behind in establishing and publishing on institutional repositories and suggests that more authors will deposit in IR in the future. A proposed role for LIS professionals is to communicate the objectives, values, and principles behind institutional repositories.

Caged laying hens are prone to calcium deficiencies, resulting in osteoporosis and egg quality deterioration during the later phase of the laying cycle. Fluorescent light and light-emitting diodes (LEDs), which are widely used in poultry houses now, are both deficient in ultraviolet (UV) light, the lack of which is detrimental to chickens’ welfare and health. This study was conducted to investigate the effects of UVB light supplementation using LEDs on the bone traits, blood parameters, laying performance, and egg quality for caged laying hens at 68–75 weeks. In total, 120 Jingfen laying hens were randomly assigned to four different groups, with three replicates in each group (10 hens in each cage as a replicate). UVB-LED lamps installed under the feed troughs were used to provide UVB light (296–316 nm) for the birds in the three treatment groups (1 h, 2 h, and 3 h UVB supplementation per day, respectively), while the control group was not exposed to UVB-LED light. Bone traits, egg quality, and amounts of calcium (Ca), phosphorus (P), 25-hydroxyvitamin D3 (25(OH)D3), 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), and 7-dehydrocholesterol (7-DHC) in both the serum and egg yolks were tested during the experiment. The results demonstrated that UVB-LED exposure significantly increased the bone mineral density (BMD), egg production, and yolk 1,25(OH)2D3 concentrations (p < 0.05), and reduced the content of serum 7-DHC (p < 0.05), especially in the 2 h/day group; however, it did not improve egg quality, vitamin D metabolites, or photoproducts in the serum and yolk 25(OH)2D3 concentrations (p > 0.05). This study concluded that UVB supplementation using LEDs had a positive effect on caged laying hens during the later phase of the laying cycle.

A review of: Xia, Jingfeng. “Assessment of Self-Archiving in Institutional Repositories: Across Disciplines.” The Journal of Academic Librarianship 33.6 (Dec. 2007): 647-54. Objective – To test the assumption that authors familiar with subject-based repositories are more likely to self-archive to institutional repositories. Design – Comparative content analysis. Setting – Institutional repositories (IRs) from the following seven universities: Queensland University of Technology (QUT), University of Melbourne, University of Queensland, Lund University, University of Glasgow, University of Southampton, and University of Strathclyde. The IRs included in the study were selected on the basis of repository size and use of EPrints software. Faculty size data and IR deposit policies were drawn from universities’ Web sites. Methods – Each IR was searched to determine the number of deposits in the disciplines of chemistry, physics, economics and sociology. Physics and economics were selected because these disciplines have established internationally renowned subject-based repositories, in contrast to chemistry and sociology, which have not. Deposits from the disciplines were identified from subject terms, keywords and departmental names in metadata records. A “deposit rate” for the four disciplines in each IR was calculated. The metadata records were examined for name of the depositor, date of deposit, full-text availability, item type, and format. Information in the field “Deposited By” was used to identify the extent of self-archiving (that is, deposited by the author). Faculty size for the four disciplines at the seven universities was established from departmental Web site information. For the purposes of making comparisons between the IRs, these data were converted into “rates of faculty” size by dividing the number of faculty in the department by the total number of faculty at the institution. A weighted rate of deposits by discipline was calculated by dividing the rate of faculty size by the deposit rates. To take into account disciplinary differences in publication productivity, these rates were subjected to further analysis. Using an “average publications per year” calculation for each discipline (from a 1977 paper), a final weighted rate of depositing was calculated for the four disciplines in the seven IRs. Main Results – Without weighting for faculty size, deposit rates vary greatly between disciplines. In most institutions, deposit rates for chemistry and sociology were higher than rates for physics and economics. When faculty size is controlled for, the highest deposit rates in five IRs were for chemistry and sociology. Only two IRs were found to have the highest deposit rates for physics and economics. These results did not change overall when the weighting for publishing productivity was applied: the same five IRs had highest deposit rates for chemistry and sociology. Exceptions to these findings were the IRs at University of Melbourne and University of Queensland, where the highest deposit rates were for economics and physics. On examination of depositor information, it was found that only 2.3% of economics deposits in the Melbourne IR were self-archived. Administrative assistants and other staff were responsible for depositing 97.7% of the IR’s economics holdings. Self-archiving of physics items to the Melbourne IR was 90%; however, these deposits comprised student theses and dissertations only. Self-archiving practices were examined for: chemistry, physics and economics deposits at the University of Melbourne; chemistry and economics at the University of Queensland; and chemistry, physics and sociology at Queensland University of Technology (the only IR in the sample with a mandatory deposit policy). Like Melbourne, self-archiving of economics deposits at the University of Queensland was also low, at 17%. Of the remaining economics deposits, a librarian was responsible for depositing 68%. Chemistry deposits at both Melbourne and Queensland had much higher self-archiving rates, 76.2% and 100% respectively, than those found for physics and economics. At QUT, where deposit into the IR is mandatory, self-archiving rates are high for the three disciplines for which findings are reported. The self-archiving rate for chemistry was 68.3%, sociology 46.3%, and physics 42.9%. A librarian was responsible for the majority of the remaining deposits. Conclusion – This research tested the proposition that disciplines familiar with subject-based open access repositories, such as physics and economics, are more likely to contribute to IRs. Its findings did not support this view. Instead, the study found no particular pattern of deposit rate across the four disciplines of chemistry, physics, economics and sociology in the seven IRs. Operational aspects of IRs, such as assisted and mandated deposit, appear to have a more significant effect on deposit rates. Assisted deposit, either through departmental administrative staff or librarians, accounted for relatively high deposit rates for economics in the Queensland and Melbourne IRs. Deposit date information in the Queensland IR suggests administrative staff of the economics department deposit to the IR on an ongoing basis. Students showed a high rate of self-archiving for theses and dissertations. It might be speculated that a mandate policy at Queensland University of Technology is responsible for the high self-archiving rates seen for economics, chemistry and sociology. However, librarians have assisted in the process, depositing over half the items for physics and sociology. The author recognises the value of both assisted and mandated deposit, but raises questions about how this will affect faculty use of IRs. For example, in cases where faculty have no role in contributing to an IR and therefore no familiarity with it, will they in fact use it? Another important consideration is the policy approach taken to temporary faculty and a mobile academic workforce. In conclusion, the author states, “Institutional repositories need a mandate policy to ensure success”.
