Norse settlement in the Inner Hebrides ca. 800-1300; with special reference to the islands of Mull, Coll and Tiree
No full textThe thesis aims to elucidate the form, extent and chronological
development of Norse colonial settlement in the Inner Hebridean islands of Mull, Coll,
Thee and Lismore in the period ca 800-1300. Tiree, Coll and Lismore are studied in
their entirety while an area from each of the parochial divisions on Mull is selected.
Historically Mull, Coll and Tiree have an essential territorial unity in
that they formed part of the territory of the cenel Loairn within the kingdom of Dalriada
in the pre-Norse period. With the division of the Isles in 1156 all three islands fell into
the hands of Somerled of Argyll and in the immediate post-Norse period remained as a
unit in the possession of the MacDougals.
Geographically the islands differ greatly from one another and show a
wide range of geological structures, landforms, soil types and vegetation, and climatic
conditions. They thus offer an opportunity for analysing settlement location,
development and expansion within a relatively small geographical area and yet one
which encompasses a variety of natural incentives and constraints. Lismore, lying to
the north-west of the above group and strategically situated at the mouth of the Great
Glen was important in the pre-Norse period as a major Celtic monastic centre. The
island is included by way of contrast, for its site and situation and close proximity to
mainland Scotland suggested that the Norse settlement of the island may have been of a
different character to that found on Mull, Coll and Tiree.
An area of the Norwegain 'homeland', the Sunnmore islands lying off
the west coast of Norway is looked at for comparative purposes. This allows an
investigation of the evolution of Norse settlement and the coining of names within a
purely Norse environment. This helps clarify the process of settlement development
and expansion and the accompanying naming practices in a colonial setting where,
particularly on Mull and Lismore, a dense Gaelic overlay often obscures salient features
of the Norse settlement pattern.
The methodology employed is both inter-disciplinary and retrospective
allowing successive layers of settlement to be 'peeled back' in order to expose the
pattern of settlement as it may have existed in the Norse period.
The thesis divides into two parts. The first analyses settlement by
settlement, the islands in question. The second concentrates on the major issues
pertinent to settlement evolution. Norse and Gaelic settlement names are discussed
together with the administrative and ecclesiastical organisation of the Isles. This leads to
the formulation of a 'model for Norse settlement' for the Inner Hebrides

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
Sitting and Television Viewing Novel Risk Factors for Sleep Disturbance and Apnea Risk? Results from the 2013 National Sleep Foundation Sleep in America Poll
No full textBACKGROUND: Excess sitting is emerging as a novel risk factor for cardiovascular disease, diabetes, mental illness, and all-cause mortality. Physical activity, distinct from sitting, is associated with better sleep and lower risk for OSA, yet relationships among sitting behaviors and sleep/OSA remain unknown. We examined whether total sitting time and sitting while viewing television were associated with sleep duration and quality, OSA risk, and sleepiness.METHODS: the 2013 National Sleep Foundation Sleep in America Poll was a cross-sectional study of 1,000 adults aged 23 to 60 years. Total sitting time, time watching television while sitting, sleep duration and quality, OSA risk, and daytime sleepiness were assessed.RESULTS: After adjusting for confounding factors (including BMI and physical activity), each additional hour per day of total sitting was associated with greater odds of poor sleep quality (OR [95% CI] = 1.06 [1.01, 1.11]) but not with other sleep metrics (including sleep duration), OSA risk, or daytime sleepiness. for television viewing while sitting, each additional hour per day was associated with greater odds of long sleep onset latency (>= 30 min) (OR = 1.15 [1.04, 1.27]), waking up too early in the morning (OR = 1.12 [1.03, 1.23]), poor sleep quality (OR = 1.12 [1.02, 1.24]), and high risk for OSA (OR = 1.15 [1.04, 1.28]). Based upon an interaction analysis, regular physical activity was protective against OSA risk associated with television viewing (P = .04).CONCLUSIONS: Excess sitting was associated with relatively poor sleep quality. Sitting while watching television was associated with relatively poor sleep quality and OSA risk and may be an important risk factor for sleep disturbance and apnea risk.Arizona State Univ, Sch Nutr & Hlth Promot, Phoenix, AZ 85004 USAUniv Pittsburgh, Sch Med, Dept Psychiat, Pittsburgh, PA USAArizona State Univ, Phoenix VA Hlth Care Syst, Coll Nursing & Hlth Innovat, Phoenix, AZ 85004 USAUniv Kentucky, Coll Med, Div Pulm Crit Care & Sleep Med, Lexington, KY USAUniversidade Federal de São Paulo, Dept Psicobiol, São Paulo, BrazilBaylor Coll Med, Sleep Ctr, Michael E DeBakey Vet Affairs Med Ctr, Houston, TX 77030 USABaylor Coll Med, Dept Med, Houston, TX 77030 USAUniversidade Federal de São Paulo, Dept Psicobiol, São Paulo, BrazilWeb of ScienceNational Sleep FoundationNational Institutes of HealthNational Institutes of Health: K23HL118318National Institutes of Health: R01HL09579
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
La identidad de aprendiz: el modelo de Coll y Falsafi
No full textEste artículo presenta algunas ideas nucleares de la noción de identidad de aprendiz propuesta por Coll y Falsafi y desarrollada posteriormente en el marco de distintas tesis doctorales, así como en publicaciones asociadas a las mismas. Con el fin de mostrar que el concepto de IdA es una herramienta de análisis y de intervención educativa especialmente relevante para ayudar al alumnado a atribuir sentido y valor personal a los aprendizajes escolares y a desarrollar la competencia de aprender a aprender a lo largo de la vida, el artículo se organiza en tres apartados. El primero está dedicado a caracterizar el concepto de identidad desde una perspectiva sociocultural del psiquismo humano y a diferenciar la IdA del autoconcepto académico, una noción próxima y con una importante tradición en psicología cognitiva. El segundo apartado presenta el modelo de construcción de la IdA desarrollado por Coll y Falsafi en dos subapartados dedicados, respectivamente, a describir las modalidades de construcción de la IdA y los componentes principales que intervienen en su construcción. El artículo se cierra con algunas consideraciones para el diseño de intervenciones educativas orientadas a ayudar al alumnado a construir una IdA cada vez más rica y habilitadora

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
