Immigration and Human Development: Evidence from Lebanon
No full textThis paper takes Lebanon as a case study to examine the relationship between human development and immigration. It examines this issue from both ends: the sending and the receiving countries. The author suggests that by developing the concept of a diasporic civil society and a diasporic public sphere, a significant aspect of the relationship between human development and immigration is illuminated especially at the level of political, social and cultural capitals. The paper also argues that the double impact of the home country and that of destination has a lot to say about the influence of immigration on human development in Lebanon. In examining Australia as a destination country, the paper shows the particular impact that globalisation and September 11 have lately had on the capacity of the Lebanese migrants for human development. Finally, the paper concludes by showing the extent to which the diasporic civil society compensates for the ‘negligent’ character of the Lebanese state in the context of human development.Lebanese diaspora, human development, diasporic civil society, diasporic public sphere, economic and social capitals
MR imaging findings in autosomal recessive hereditary spastic paraplegia
No full textBACKGROUND AND PURPOSE: Hereditary spastic paraplegia (HSP) is a disorder characterized by degeneration of the corticospinal tracts and posterior column of the spinal cord. Previously described radiologic findings included nonspecific brain abnormalities such as brain atrophy and white matter lesions, as well as atrophy of the spinal cord. In our study, we aimed to better characterize brain and spine MR imaging findings in a series of patients with HSP. MATERIALS AND METHODS: Nine patients from 4 different Lebanese families with the autosomal recessive form of HSP were included in the study. All patients underwent brain and whole-spine MR imaging. We assessed the presence of white matter abnormalities mainly along the corticospinal tracts, brain atrophy, thinning of the corpus callosum, and the presence of spinal cord atrophy or abnormal signal intensity. RESULTS: Imaging revealed mild brain atrophy (44percent), atrophy of the corpus callosum (55percent), white matter lesions (67percent), abnormal T2 high signal intensity in the posterior limb of the internal capsule (55percent), and mild spinal cord atrophy (33percent). CONCLUSIONS: The MR imaging findings of HSP are nonspecific and variable; however, the most prominent features include atrophy of the corpus callosum, T2 signal intensity in the posterior limb of the internal capsule, and spinal cord atrophy.Alber B, 2005, J NEUROL SCI, V236, P9, DOI 10.1016-j.jns.2005.03.040; Auer-Grumbach M, 1999, J NEUROL, V246, P556, DOI 10.1007-s004150050403; BRUYN RPM, 1992, CLIN NEUROL NEUROSUR, V94, pS16; CAMBI F, 1995, ARCH NEUROL-CHICAGO, V52, P665; Casali C, 2004, NEUROLOGY, V62, P262; Coutinho P, 1999, ARCH NEUROL-CHICAGO, V56, P943, DOI 10.1001-archneur.56.8.943; Dreha-Kulaczewski S, 2006, NEURORADIOLOGY, V48, P893, DOI 10.1007-s00234-006-0148-2; DURR A, 1994, NEUROLOGY, V44, P1274; FERRER I, 1995, NEUROPATH APPL NEURO, V21, P255, DOI 10.1111-j.1365-2990.1995.tb01057.x; GILMAN S, 2002, MANTER GATZS ESSENTI, P181; GOLDBLATT J, 1989, CLIN GENET, V35, P116; HARDING AE, 1984, HEREDITARY ATAXIAS R, P191; Hedera P, 2005, NEURORADIOLOGY, V47, P730, DOI 10.1007-s00234-005-1415-3; HOURANI R, 2008, EUR J RADIOL EXTRA, V65, P37, DOI 10.1016-j.ejrex.2007.11.009; Kassubek J, 2006, EUR J NEUROL, V13, P880, DOI 10.1111-j.1468-1331.2006.01380.x; KEPPEN LD, 1987, AM J HUM GENET, V41, P933; Krabbe K, 1997, NEURORADIOLOGY, V39, P724; Kuru S, 2005, NEUROPATHOLOGY, V25, P346, DOI 10.1111-j.1440-1789.2005.00620.x; Lesca G, 2003, NEUROLOGY, V60, P674; MARTIFABREGAS J, 1990, NEUROLOGY, V40, P1799; Moller-Hartmann W, 2002, NEURORADIOLOGY, V44, P371, DOI 10.1007-s00234-001-0760-0; NAKAMURA A, 1995, J NEUROL SCI, V131, P35, DOI 10.1016-0022-510X(95)00028-Z; NICOLAU A, 1987, PEDIATRIE, V42, P359; Nielsen JE, 1998, J NEUROL NEUROSUR PS, V64, P61, DOI 10.1136-jnnp.64.1.61; Nomura H, 2001, NEUROPATHOLOGY, V21, P212, DOI 10.1046-j.1440-1789.2001.00388.x; Ohnishi J, 2001, ACTA NEUROL SCAND, V104, P191, DOI 10.1034-j.1600-0404.2001.00032.x; Okubo S, 2000, ACTA NEUROL SCAND, V102, P196, DOI 10.1034-j.1600-0404.2000.102003196.x; Orlacchio A, 2004, ARCH NEUROL-CHICAGO, V61, P849, DOI 10.1001-archneur.61.6.849; ORMEROD IEC, 1994, J NEUROL NEUROSUR PS, V57, P51, DOI 10.1136-jnnp.57.1.51; Proukakis C, 2004, J NEUROL, V251, P1105, DOI 10.1007-s00415-004-0491-3; Somasundaram S, 2007, PEDIATR RADIOL, V37, P503, DOI 10.1007-s00247-007-0444-y; Sperfeld AD, 2005, EUR NEUROL, V53, P74, DOI 10.1159-000084650; Sperfeld AD, 2005, EUR NEUROL, V54, P181, DOI 10.1159-000090294; Sperfeld AD, 2004, J NEUROL, V251, P1285, DOI 10.1007-s00415-004-0562-5; Teive HAG, 2001, ARQ NEURO-PSIQUIAT, V59, P790, DOI 10.1590-S0004-282X2001000500025; Winner B, 2004, ARCH NEUROL-CHICAGO, V61, P117, DOI 10.1001-archneur.61.1.117810

Left-sided cervical aortic arch associated with pseudocoarctation, aneurysm formation, and anomalous left brachiocephalic vein: Appearance on MDCT and MR angiography
No full textCervical aortic arch (CAA) is a rare congenital aortic anomaly. It can be associated with several cardiovascular abnormalities including aortic aneurysm, valvular disease, and pseudocoarctation. In this report, we present a case of CAA with combined association of both aneurysm formation and pseudocoarctation. This combination of anomalies is extremely uncommon, described in only 4 cases in the literature. In addition, our patient had an anomalous subaortic left brachiocephalic vein that, to our knowledge, was not previously described in the literature to be associated with CAA. The radiographic, multidetector computed tomography scan, and magnetic resonance angiography imaging findings are presented.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
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

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
