Origination and extinction patterns of mammals in three central Western Mediterranean islands from the Late Miocene to Quaternary
2008
Abstract An overview of the population histories of three insular realms (Gargano palaeo-archipelago, Sardinia–Maritime Tuscany palaeo-bioprovince and the Sicilian insular complex) during the Late Miocene and Quaternary are here presented. The complexity of biodiversity changes in the islands is analysed to propose an interpretation of origination and extinction patterns. The study highlighted several important aspects of insular faunas. Evolutionary radiations were found to contribute significantly only to the Gargano faunal diversity, likely because the area was an archipelago at the time. Another interesting result is that large and small mammals do not disperse and become extinct all at…
Habitat Preferences for Territory Selection by the Endangered Eastern Iberian Reed BuntingEmberiza Schoeniclus witherbyi
2014
Summary. Given the 80% decline of the eastern Iberian reed bunting Emberiza schoeniclus witherbyi breeding population in recent decades, our aim was to identify the habitat components selected during territory establishment and to characterise the vegetation features that are positively or negatively selected at the territory scale. GLMM were used to explain the occurrence of territories in 11 wetlands. Fourteen variables with four vegetation dominance categories were analysed with respect to habitat composition, while occupancy of seven vegetation classes and 12 reed structural parameters were analysed with respect to habitat structure. The proportion of reed-cattails (Typha) measured by t…
Occurrence of three different binding sites forBacillus thuringiensisδ-endotoxins in the midgut brush border membrane of the potato tuber moth,phthor…
1994
The potato tuber moth is susceptible to at least three insecticidal crystal proteins (ICPs) from Bacillus thuringiensis: CrylA(b), CrylB, and CrylC. To design useful combinations of toxin genes either in transgenic plants or in new genetically modified B. thuringiensis strains, it is necessary to determine the binding characteristics of the different ICPs so as not to combine a pair sharing the same binding site. This has been accomplished using two different techniques: 125I-labeling of the ICPs with further measurement of the radioactivity bound to brush border membrane vesicles, and microscopic visualization of the bound ICPs by enzyme-linked reagents such as antibodies or streptavidin u…
Factorial Structure and Psychometric Properties of the Sensation Seeking Scale – Form V (SSS-V) in a Sample of Italian Adolescents
2013
The present study was designed to evaluate the psychometric properties of the Sensation Seeking Scale – Form V (SSS-V) for the Italian-speaking population. The instrument was administered to 1,530 high school and college students. A second group of 268 high school students completed the SSS-V and the Impulsiveness Questionnaire (IVE). Exploratory factor analysis highlighted a 2-factor structure, Thrill and Adventure Seeking (TAS) and Disinhibition (Dis). Confirmatory factor analysis revealed an adequate model fit. Internal consistency of the subscales was marginally supported using the alpha reliability measure. Convergent validity was supported by significant positive correlations between …
COVID-19 and globalization
2020
The world is experiencing a major pandemic caused by SARS-CoV-2, the Coronavirus causing COVID-19. This disease first entered the human population in Hubei province, China, in mid-November 2019 and manifested in Wuhan, the largest metropolitan area of Hubei, when a cluster of patients were admitted to hospital with a ‘severe pneumonia of unknown cause’ in early December. Although humanity has survived previous pandemics by infectious agents, the present one is unprecedented in its capacity to take advantage of modern globalization allowing for massive transborder spread at a surprising speed. When writing these lines, the pandemic affects 181 countries and territories, with around 1,084,000…
Protocol, politics and popular culture: the independence jubilee in Gabon
2013
National days are powerful moments of commemoration that aim at renewing the citizens' bonds to the nation and the state. In order to be successful, public rituals need to draw large audiences, and their ceremonial design therefore has to be adapted to suit the masses, employing elements of popular culture and everyday forms of nationhood. Despite drawing its significance from the declaration of independence in 1960, however, Gabon's independence jubilee was less concerned with history and commemoration than with celebrating the state and the nation in the present. The ceremonial design of Gabon's jubilee featured intensive preparations, official ceremonies, popular festivities and symbolic…
Economic Factors of Labor Migration Analysis
2021
Population of Latvia is declining every year due to rate of natural decrease and negative rate of net migration indicators [1]. It is a topical issue since it affects stability and growth of the country.
A new approach to the Late Miocene-Early Pliocene forms of the genus Apocricetus. Apocricetus alberti (Rodentia, Mammalia) from Venta del Moro (Cabri…
2014
Abstract The species of the genus Apocricetus are considered to form the phyletic lineage A. aff. plinii (MN11)– A. plinii – A. alberti – A. barrierei – A. angustidens (MN16). Along this lineage, gradual morphological and biometrical changes occur, but not all the species are represented by rich populations. The assemblage of Apocricetus alberti from Venta del Moro is by far the most abundant collection of this species. This population shows a great morphological variability in some characters like the morphology of the anteroconid and the anterolophulids in m1 and the shape of the anterolophule in M1, with morphotypes that resemble both older and younger populations of Apocricetus . Along …
HUMAN VALUES AND ATTITUDES TOWARDS MONEY
2018
Spending money which is not earned becomes more available practice with help of the various types of cash loans. It causes social problem in society because easiness of getting money puts families at risk due to the high loan percent. Our study aims to understand ifhuman values are related to attitudes towards money and in what way if any.Values are motivational constructs that apply to abstract goals (Schwartz, 1992). Schwartz believes that the main aspect of value contents is the type of goal or the motivation it expresses (Schwartz, 1992). Also, values are abstract goals and do not effect decisions in specific situations they can work as the underlying assumptions for creating attitudes.…
Arithmetic disabilities with and without reading difficulties: A comparison of arithmetic errors
1995
Arithmetic errors of 80 children with arithmetic disabilities, representing 3% of a population‐based sample, and of 80 sex‐ and age‐matched control children were systematically analyzed. In Analysis 1, covariance structure modeling (LISREL) was applied to analyze relations between reading, as measured by text reading accuracy and speed, and arithmetic error types. The results demonstrated that reading accuracy and speed were connected to errors in multiplication fact retrieval. In Analysis 2, a classification of children with arithmetic disabilities into subgroups by reading accuracy and speed difficulties revealed that children with dysfluent reading made more fact‐retrieval errors than di…
