Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Religious pathways to coping with personal death anxiety among older adult British Christians and Chinese Buddhists: afterlife beliefs, psychosocial maturity and regret management
No full textReligion was proposed to account for the relatively low personal death anxiety found among older adults. This dissertation sought to examine the influence of religious afterlife beliefs, religiously enhanced psychosocial maturity and religious management of a past major regret on personal death anxiety in later life. Terror Management Theory and Erikson’s Psychosocial Theory were used to describe these three religious pathways to coping with personal death anxiety in later life. The cross-sectional postal survey samples consisted of 143 older adult British Christians and 141 older adult Chinese Buddhists. Structural Equation Modelling results from the British Christian survey study showed that intrinsic religiosity predicted lower personal death anxiety through: (a) fostering more benign afterlife beliefs; (b) enhancing psychosocial maturity; and (c) promoting emotional stability. No significant relationship between belief in reincarnation and personal death anxiety was found in the Chinese Buddhist survey study. Both survey studies failed to support the personal death anxiety buffering power of religious management of a past major life regret, although some religious coping strategies were associated with lower negative emotional appraisal towards the major life regret among older adults. The British survey study has been the first to demonstrate both the personal death anxiety buffering and psychosocial maturity enhancing power of religion in an increasingly secular society. The lack of relationship between Buddhist reincarnation beliefs and personal death anxiety suggests that not all religious afterlife beliefs have death anxiety buffering power as proposed by Terror Management Theory. The development of Buddhist reincarnation belief and Buddhist coping scales is a pioneering step towards developing research on under-explored Eastern non-theistic afterlife beliefs and coping measures. Implications for ways that help religious older adults cope with their personal death anxiety were discussed. Prospective cross cultural and cross-religion studies were recommended to replicate the present survey findings. Finally, self detachment (self negation) was proposed as the basis of an alternative death transcendence theory to be researched in future studies on personal death anxiety
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Scalable, epitaxy-free fabrication of super-absorbing sparse III-V nanowire arrays for photovoltaic applications
No full textIII-V compound semiconductor nanowire arrays are promising candidates for photovoltaics applications due to their high volumetric absorption. Uniform nanowire arrays exhibit high absorption at certain wavelengths due to strong coupling into lossy waveguide modes. Previously, simulations predicted near-unity, broadband absorption in sparse semiconductor nanowire arrays (<5% fill fraction) with multi-radii and tapered nanowire array designs [1]. Herein, we experimentally demonstrate near-unity broadband absorption in InP nanowire arrays via a scalable, epitaxy-free fabrication method, using nanoimprint lithography and ICP-RIE to define nanowire arrays in bulk InP wafers. In addition to mask pattern design (wire radius and spacing) and etch chemistry (wire taper), appropriate selection of a hard mask for the InP etch is critical to precise dimension control and reproducibility. Polymer-embedded wires are removed from the bulk InP substrate by a mechanical method that facilitates extensive reuse of a single bulk InP wafer to synthesize many polymer-embedded nanowire array thin films. Arrays containing multiple nanowire radii and tapered nanowires were successfully fabricated. For both designs, the polymer-embedded arrays achieved ~90% broadband absorption (λ=400-900 nm) in less than 100 nm planar equivalence of InP. The addition of a silver back reflector increased this broadband absorption to ~95%. The repeatable process of imprinting, etching and peeling to obtain many nanowire arrays from one single wafer represents an economical manufacturing route for high efficiency III-V photovoltaics
Arsenic in drinking water caused ultra-structural damage in urinary bladder but did not affect expression of DNA damage repair genes or repair of DNA damage in transitional cells
No full textArsenic is a human carcinogen associated with urinary bladder transitional cell carcinoma and other cancers. Arsenic is also a strong comutagen and cocarcinogen. One possible mode of action for arsenic carcinogenesis/cocarcinogenesis is inhibition of DNA damage repair. In laboratory animals, urinary bladder transitional cell carcinoma has only been observed in dimethylarsinic acid [DMA(V)]-exposed F344 rats.
The goal of the present studies was to investigate inhibition of DNA repair as a mode of action for arsenic carcinogenesis/ cocarcinogenesis in the urinary bladder. Methods were first developed to harvest only transitional cells, the target cell type of arsenic carcinogenesis, suitable for RNA extraction or for DNA damage detection by Comet assay. Morphological studies established that DMA(V) in drinking water at 40 ppm was cytotoxic to the urothelium of Sprague-Dawley and F344 rats, and mitochondria were targeted by DAM(V).
To investigate whether DMA(V) decreases the expression of DNA repair genes, mRNA levels of DNA repair genes in transitional cells were next measured in F344 rats exposed to up to 100 ppm DMA(V) in drinking water for 4 weeks. The mRNA levels of Ataxia Telangectasia mutant (ATM), X-ray repair cross-complementing group 1 (XRCC1), excision repair cross-complementing group 3/Xeroderma Pigmentosum B (ERCC3/XPB), and DNA polymerase beta genes were not altered, as measured by real time RT PCR. These results suggested either that DMA(V) affects DNA repair without affecting the baseline expression of DNA repair genes or that DMA(V) does not affect DNA repair in the bladder.
Arsenic effects on DNA repair were further investigated in F344 rats given 100 ppm DMA(V) or arsenate in drinking water for 1 week. DNA damage levels in transitional cells and micronuclei frequency (MN) in bone marrow were measured. Dimethylarsinic acid did not affect in vivo cyclophosphamide-induced DNA damage, and neither DMA(V) nor arsenate inhibited in vitro repair of hydrogen peroxide- or formaldehyde-induced DNA damage, as measured by Comet assay. Neither DMA(V) nor arsenate increased MN or elevated in vivo cyclophosphamide-increased MN. These results suggest inhibition of DNA repair by arsenic, in the transitional epithelium, may not be a major mechanism responsible for carcinogensis/cocarcinogenesis in the bladder.Ph. D
Finding Aid: MS 546 - Lu Hui Ching's Research and Training Institute for Physical & Health Education in China papers
No full textThe MS 546 - Lu Hui Ching's Research and Training Institute for Physical & Health Education in China papers represent the efforts of Lu Hui Ching (Lu Huiqing/卢慧卿), a doctorial graduate of Columbia Teachers College, to establish a Research and Training Institute for Physical and Health Education in China. She was mentored by Dr. Josephine Rathbone in this effort, who also is well-represented in the collection in correspondence and official documentation. Support for the project was sought internationally, and a committee was formed that met multiple times from 1948 through 1949. Funding sources were researched and plans for establishing fellowships were explored. A Bank account was established for the project. It should be noted that while the efforts were being made in support of this project, China was in the midst of a civil war and there was dramatic political turmoil. On September 1, 1948, the Communist party proclaimed the North China People’s Government. Only a year later, on October 1, 1949, Communist leader Mao Zedong declared the creation of the People’s the Republic of China (PRC) and the central government fled to Taiwan. These events are reflected within the documents in the collection.
Materials with the collection include notes, meeting minutes, planning documents, reports, financial materials, questionnaires, and correspondence. Most of the materials come from 1948 and 1949. Correspondence is in English, though there are some letters written in Chinese.
Correspondence makes up a fair portion of the collection. Most of the correspondence is written by or written to Lu Hui Ching and Dr. Josephine Rathbone. Correspondence between important physical educators at the time includes Dr. Dorothy Ainswort, Charles H. McCloy, Ruth Evans, Peter V. Karpovich, Emily Case Keefe, and Jesse Feiring Williams. There is a letter to John ma (Yuehan Ma), but no origianl correspondence from him. There are multiple letters written by Dong Shouyi (Tung Shou Yi). Other correspondents of import are Dr. Han Li Wu, Ministry of Education in China, John Leighton Stuart, Ambassador to China, Kuan Yu-Shan, a possible fellowship candidate, T. C. Tang, and Chih Meng, the Director of China Institute In America. There are also correspondence between Yenching University and the True Light Middle School in Guangzhou located in the Canton or Quandong province of China. Other organizations contacted included UNSECO, the Hazen Foundation, the United Nations, and the Kellogg Foundation. Of particular interest is a letter to Dr. Paul Limbert, President of Springfield College asking Springfield College to take custody of these materials and Dr. Clarence Linton's letters stating his opinion that the project could not work at this time due to the political climate in China.
In addition to correspondence there are reports and desicriptions of the project, including drafts of these documents. Some of these descriptions come in the form of correspondence or marketing sent to educators and founding organizations. One such mailing was sent to educators in China along with a questionnaire regarding the state and needs of physical education in China. There is a folder of returned questionnaires within the collection. Also included in this mailing was a letter of support from the True Light Middle School and the support of the Yenching Univeristy and its faculty. Meeting minutes from the Preparatory Committee on the project are included. As are financial records, including cancelled checks and deposit records through the accounts' closing on May 31, 1950.
Finally there are some biographical information contained on Lu Hui Ching. This includes a CV, copies of some personal materials like information from Camp Wabunaki in Maine and text from a short talk she gave for an AAPE (American Alliance of Physical Education) on April 17, 1949. Of note is an interview she gave on the project with the I.O.E. Broadcasting program on February 7, 1949.For more information about Lu Hui-chʻing, see:https://springfield.as.atlas-sys.com/agents/people/97
