Report on Investigations in Greece. XI. Studies in 1995-2003

The existence of subjects in a society is accepted in groups formed on the basis of gender and in communities and thus gains meaning. We have heard the statement "does a manly man do such a thing?" so many times when a man displays behaviour outside the gender roles described for men in the practice of social structure. It is necessary to look at the components constituting manliness and to examine the behavioural practices with which those components are related so as to understand the status called manliness.

This study is a review of Quaternary Milankovitch cycles as recorded on modern continental shelves worldwide. On the background of the many existing examples, we focus on selected case studies from Mediterranean (Adriatic and Tyrrhenian seas) and Atlantic (gulfs of Mexico and Cádiz) margins that represent general and peculiar characters of Middle-Upper Pleistocene sequences forming under the control of composite 100 and 20 ka Milankovitch cycles. The most pervasive stratigraphic pattern displayed by shelf deposits is referred to the 100 ka sea-level cycle, and consists of fairly uniform depositional sequences mostly composed by regressive deposits forming during the falling limb of the sea-level curve. These are generally classified as Falling Stage Systems Tract (FSST) and display a regressive facies architecture reflecting the dominant control of sea level. On many margins, FSST units may show slight though significant differences with respect to Highstand Systems Tract (HST) and Lowstand Systems Tract (LST) regressive units, more closely reflecting environmental changes and the local variability of depositional systems. In contrast with the theoretical and overall scale-independent model developed to predict composite stratigraphic cycles and sequences, the Middle-Upper Pleistocene stratigraphic record from numerous shelf settings shows a subdued signature of the higher-frequency (20 ka) Milankovitch cyclicity. However, when detectable, the 20 ka architectural pattern is characterized by a relatively greater spatial and temporal variability compared to 100 ka sequences. This fact likely reflects the increasing importance of factors controlling the depositional environment (e.g., seafloor morphology, oceanographic regime, sediment input and dispersal, etc) with respect to sea-level change during the shorter intervals encompassed by 20 ka cycles. On this basis, two end-member cases have been distinguished, depending on the generation or not of high-frequency sequence boundaries, a prerequisite to qualify the higher-frequency motifs as depositional sequences. These two end members are comprehensive of the highly variable patterns displayed by Middle-Upper Pleistocene shelf sequences, which in turn reflect the interplay between the geological setting, the dominant sea-level control and the effective response of sedimentary systems. The variable stratigraphic patterns of Milankovitch cycles represent conceptual and practical constraints as to the classification of high-frequency Quaternary sequences under the general schemes of the standard sequence stratigraphy model.

Northern Italy has often been characterised as an isolated and marginal area during the Roman period, a region constricted by mountain ranges and its distance from major shipping lanes. Historians have frequently cited these obstacles, alongside the lack of a major seaport on the Po, as a barrier to the region's economic development and connectivity to the rest of the Roman world. However, how isolated was the interior of Northern Italy in reality? To answer these questions, this paper analyses the results of a route network model of Northern Italy's transport network during the Roman period. Containing over 136 nodes, it enables a significantly more detailed analysis of the region's transport network than previous modelling. The model explores which were the most cost-effective routes for imports arriving from the Adriatic and Ligurian coasts, alongside which ports were the most accessible from sites in the upper and middle valley. The paper's results confirm the importance of the Po-Veneto water network in facilitating the cost-efficient movement of goods from the Adriatic coast to areas hundreds of kilometres inland and vice versa, suggesting that prior assumptions of its isolation have been overestimated .

En las industrias o fabricas se emplean elementos metálicos, por el mismo motivo de utilizar estos materiales se debe realizar diversos procesos tales como: soldadura, pero uno de los más importantes es el corte (quitar una parte de un todo), por consiguiente se utilizan varios tipos de máquinas, herramientas, con el propósito de eliminar la fuerza humana, entre una de ellas es la cizalla mecánica, que nos permitirá reducir el tiempo En este presente trabajo de investigación vamos a realizar un estudio minucioso sobre el proceso de corte por cizalla mecánica, tanto su funcionamiento, utilización con el fin de generar nuevos conocimientos.

This mixed method study explored the relationship between the employment of professional managers and wealth creation in small-medium enterprises. Specifically, the study attempted to determine whether professional managers contribute to the profitability of small-medium enterprises in the secondary wood manufacturing industry. Furthermore, the study investigated the reasons why entrepreneurial firms have difficulty attracting and retaining professional managers. The study involved 36 secondary wood manufacturing firms engaged in the manufacture of a variety of products. The research validated that the more professional managers entrepreneurial firms employ, the greater profitability they realize and furthermore, entrepreneurial firms face major challenges in their pursuit to attract and retain professional management.

Similarly in a 1991 South African study, it was found that of every 1,000 births 330-400 are to teenagers less than 19 years old. In addition, the study conducted by the Human Sciences Research Council on South African fertility trends in 1994 found that 48% of Black women, 17% of Coloured women, 30% of Indian women and 17% of White women gave birth before turning 20 years of age (National Population Unit, in press 2003). The differences in incidence of teenage pregnancy among racial and ethnic groups result from socioeconomic factors. Teenage pregnancy is prevalent in societies characterised by poverty, low education, fewer job opportunities and families headed by mothers who gave birth to their first children in adolescence (Dryfoos, 1996; Macleod, 1999). Teenage pregnancy is also associated with other problematic behaviour such as alcohol and drug use, and early initiation of sexual activity, which have been identified as predictors of pregnancy (Coley & Chase-Lansdale, 1998; National Population Unit, 2000). Plant & Plant (1992) argue that risk or problem behaviour is associated with social disadvantage, poverty, homelessness, unemployment, bad housing, fragmented family structure and stressful life events. The youth emulate the behaviour of their parents and of their society, thus social and cultural factors influence patterns of risk taking (Plant & Plant, 1992). Early initiation of reproductive behaviour varies widely across countries and between subgroups in the same country. In some societies a woman's first sexual experience often happens within a marriage, while in other societies sexual activity outside marriage is tolerated. For instance, in North Africa young women are less likely to initiate sexual relationships before marriage, while in most sub-Saharan African countries most teenage girls have sexual relationships which sometimes lead to marriage (The Alan Gutchmatcher Institute, 1998). Prevailing societal norms and values as determined by social, economic, cultural, psychological and developmental factors have influence on the behaviour of its youth. There is increasing evidence that adolescents are influenced by their environment, therefore reproductive behaviour might be influenced by community characteristics (National Population Unit, 2000). Much research has been done on factors that predispose girls to falling pregnant in their adolescent years (Furstenberg, Brooks-Gunn & Morgan, 1987; Dryfoos, 1990).
