Who Shall Receive Community-Based Occupational Therapy Services? A Logistic Regression Analysis
No full textAbstract
Date Presented 3/30/2017
Two predictive models of occupational therapy referral were proposed as triage protocols for decision making in community. This finding can help occupational therapists focus on the major predictors of services, case managers make proper referrals, and third-party payers validate the appropriateness of referrals.

“Antología de un amor intangible” de Martha Ling Hui: Una carta de amor en pleno siglo XXI
No full textWhen the book “Anthology of an Intangible Love” fell into my hands, I found the author’s surname, Ling Hui, curious. I thought: is she of Asian origin? The afternoon I received the book, it was raining, and I asked myself, when has love been tangible? Mora (2018) points out that “It is worth saying that there is no evidence that unicellular organisms, viruses, or subatomic particles love” (p. 1), which indicates that no matter how much love is attributed to being tangible, it goes beyond a physical quality. Intangible love is that immaterial force that unites particles even if they are separated by stars and galaxies.Cuando el libro “Antología de un Amor Intangible” cayó en mis manos, me pareció curioso el apellido de la autora, Ling Hui, pensé: ¿acaso es de origen asiática? La tarde que recibí el libro, estaba lloviendo y me pregunté ¿cuándo ha sido tangible el amor? Mora (2018) señala que “Vale la pena decir que no existe evidencia que los organismos unicelulares, virus o partículas subatómicas amen” (p.1), lo que indica que por mucho que se le atribuya a que el amor es tangible, va más allá de una cualidad física. El amor intangible es aquella fuerza inmaterial que une partículas aún si estas están separadas por estrellas y galaxias.
 
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Rationing Rules and Outcomes: The Experience of Singapore's Vehicle Quota System
Full text linkSince 1990, Singapore has sought to control motor vehicle ownership by means of an auction quota system, whereby prospective vehicle buyers need to obtain a quota license before they can make their purchase. This paper assesses the success of the vehicle quota system in meeting its objectives of stability in motor vehicle growth, flexibility in the motor vehicle mix, and equity among motor vehicle buyers. Two important implementation issues - quota subcategorization and license transferability - are highlighted, and policy lessons are drawn for the design of auction quotas in general.

The Study of the Shade Tolerance of Southern India Type Vetiver (Vetiveria zizanioides (L.) Nash)
No full text台灣地區地震發生頻繁，山坡地表嚴重裸露，再加上雷豪雨的沖刷、山坡地不當的過度開發及工業與生活污水的不當處理和排放等，不僅使得土壤極易流失與劣化，水資源更遭受污染，故在種種環境日益惡化的壓力之下，水土保持與環境復育的工作刻不容緩。而培地茅健壯的生長及生理特性，不僅可以作為坡地保固之材料，更適合作為廢棄荒地生態復育工程的先驅植物。然而，台灣夏季雖然炎熱，但夏日午後常見的熱雷雨所帶來的雲層、春夏之際梅雨季節長達數天乃至數週的滯留鋒面及空氣懸浮微粒的遮蔽效應對需要高日照量的培地茅之影響不容忽視。本研究即針對現有的27種培地茅品系做遮蔭逆境之篩選。以田間及人工照明室內遮蔭處理的葉部生長型態（葉厚及比葉鮮重）、葉綠素相關測值（葉綠素計讀值、以N,N-dimethylformamide所萃取出的總葉綠素含量、葉綠素a含量、葉綠素b含量及葉綠素ab比值）及溫室內遮蔭處理之光合潛力（光飽和點、光飽和光合作用速率、光補償點及暗呼吸作用速率）為度測標準，探討此27種培地茅品系在遮蔭逆境下的改變及其面對遮蔭逆境所表現出來的可塑性，甚至觀察比較是否本身即具有在基因型上耐遮蔭逆境之可能性指標，以期在實際生態復育、水土保持及遺傳育種上能更有效的被開發利用。
然而，本試驗所針對的一些偵測性狀特徵，雖然在遮蔭處理下大致都表現出相關學理上所應該呈現的趨勢，即培地茅的葉片變得較薄、比葉鮮重降低，葉綠素相關測值含量皆增加，在光合潛力上也因遮蔭逆境之影響而降低。但這些性狀特徵都不足以作為判斷一品系是否具有耐遮蔭性之統一指標。在所有偵測性狀之可塑性比較上，或可呈現該品系面對遮蔭逆境下所做的應對能力之探討及適應遮蔭逆境優劣之參考，但有些品系對不同性狀之可塑性反應不一致，可見遮蔭逆境所能影響的層面廣泛，不太能針對某一方面來單獨的探討其耐受性，特別是本試驗所偵測的培地茅皆屬同一物種。此外，試驗亦將所偵測的性狀特徵與培地茅遺傳距離樹狀分枝圖相做比較，但亦未發現有任何一項量測值與用來估算遺傳歧異度的DNA分子標記有相關。
遮蔭逆境是一種長期累積的效應，特別是針對根系發達，地下部組織旺盛，且株叢龐大，地上部分蘗多而繁密的培地茅而言。本試驗雖仍未發現培地茅耐遮蔭性之可能性指標，但其中也有許多值得再討論與改進之處，供作日後繼續篩選其他可能的耐遮蔭性指標性狀試驗設計之參考。The landscape in Taiwan is suffering naturally from frequent earthquake and storm and thus becoming highly vulnerable to erosion. The human activities including over-exploitation in the mountain area further worsen the situation. The effluent from the industry and urban development pollute the water supply is getting seriously. Hence, the recognition of the erosion control and restoration of the environment is prevailed in the general public. The vetiver grass with extensive root system and strong stems is suitable as pioneer species for the degraded soil and water and been used in many applications. The regular tropical storm happened in the afternoon in summer has significant impact on the intensity and amount of the light that vetiver received. The prolonged rainy season during the end of spring and smog from the air pollution has also contribute to the reduction of light available to vetiver. Thus the study of effect of shading on vetiver becomes a major issue. Twenty seven lines of vetiver were used in the study. The response of leaf morphology and chlorophyll content to the shade treatments conducted in the field and artificial lighting in phytotron were evaluated. The photosynthesis characteristics including light saturation point, light compensation point, light-saturated photosynthetic rate and dark-respiration rate were measured in the greenhouse. The results indicated general agreement with published hypothesis and principles, but discrepancies were also identified. One of the primary interests in this study was to identify traits suitable for selection for shade tolerant genotypes and the evaluated traits were proved to be unable to provide unambiguous results. The study of shade tolerance is complicated by the perennial nature of vetiver grass. It should be investigated further.目錄
