In this Bachelor thesis an animal bone material from Västergarn parish is analyzed and discussed. The purpose of this thesis is to gain more knowledge about the Viking Age/Early Medieval Västergarn. Västergarn has a few remains from former days which have been discussed throughout the years and are still a bit of a mystery for archaeologists. The main focus is to inquire into whether Västergarn was an urban, complex society or a rural settlement. This will be done by studying the animal husbandry from the property of Snauvalds 1:2. The animal bones have been typed, and sex and age estimations have been made on the most common domestic animals, ergo cattle, sheep/goat and pig. The result from the analysis shows that Västergarn has tendencies of both countryside settlement and a more urban society and the final conclusion is that it has most probably been a trading place or a market place considering its closeness to a Viking Age harbor.

Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging. The aim of this paper is to do analyze the theories of several researchers, considering the urban development of Visby. The results show that the area of Visby has been a place that has been used since Stone Age, during the Viking age the area was a place for season trade. According to the archaeological sources is it not an indication of at town during the Viking age, because of the lack of permanent buildings.

I tidigare empatiforskning har könsskillnader studerats betydligt mer änåldersskillnader. Syftet med den aktuella undersökningen var att studera hurförmågan till empati skiljer sig mellan tonåringar, medelålders och äldre. Iundersökningen deltog 68 personer varav hälften kvinnor. Empatin varhögst i den äldsta gruppen och lägst i den yngsta för både kvinnor och män.Däremot kände tonåringarna mer för vissa känslor som mättes utanförempatiskalan. Kvinnorna i alla tre åldersgrupperna har högre empati änmännen. Att empati ökar med åldern säger samtidigt att yngre hade mindreempati. Resultaten kan tyda på att samhället blivit kallare. Avslutningsvisdiskuteras betydelsen av generationsskillnader i empati, en eventuellutveckling mot ett mindre empatiskt samhälle, samt om ungas empati kanstärkas i framtiden.

Prospective memory also known as remembering to remember is the process of remembering to carry out future actions. The present study investigated age-related differences in the performance of two complex prospective memory tasks for 30 younger adults (M = 19.43, SD = 2.10) and 30 older adults (M = 66.87, SD = 3.25). The two tasks had the same constraints, but were framed within different contexts (i.e., taking medications or scheduling groups). Participants performed the tasks within a simulated week based on activities they perform as part of their weekly routine, and they were given 30 minutes to develop plans to help them remember the tasks. Older adults were as accurate as younger adults in developing their plans for both tasks, but made significantly more errors in carrying out the prospective tasks. Planning style was not directly predictive of performance for the group task. However, age-related differences in performance for the medication task were related to planning style such that age-related declines in performance were observed for older adults who used a planning style that did not provide adequate memory support (i.e., list layout with time cues). Moreover, participants of all ages with lower levels of planning experience were more likely to select this ineffective planning style. These findings provide evidence that age-related differences in prospective memory can be ameliorated through the use of a familiar task and the opportunity to develop plans to remember the task. However, if participants develop an ineffective plan they will show performance decrements.

Information in a message can either be fully expressed (explicitly) or indirectly stated (implied) and understood by inference or association. Previous research suggested an age-related decline in performance of implicit compared to explicit information and that this relationship is moderated by prior knowledge. Whereas previous studies mainly obtained quantitative data of inferencing performance, the current study employed both quantitative and qualitative techniques to understand age-related differences in inferencing. Twenty younger and older participants evaluated whether a series of one-sentence statements were true or false based on specific two-sentence text passages. Text passages either resembled real warnings (taken from actual products) or were novel (the opposite of a warning found on an actual product). Statements either explicitly stated information from the text passage or required participants to go beyond information given in the text. Quantitative analysis showed that older adults accuracy compared to that of younger adults when evaluating real text passages, with explicit items being evaluated more accurately than implicit items. For novel text passages (generally lower accuracy scores), younger adults showed the same pattern as for real text passages, whereas older adults accuracy was low for both explicit and implicit statements. Qualitative analyses supported that participants correct answers generally reflected that the intended inference was drawn and that for incorrect answers the inference was not mentioned. The data also suggested that accuracy scores may underestimate the actual ability to infer. Both age groups mentioned most often that text-related factors (e.g., clarity) influenced their decision and brought outside information (e.g., education, experience, expectations) to the task regardless of text passage or statement type. Older adults more often referred to outside information than younger adults, particularly when evaluating novel text passages and their answer was wrong. This study substantiated that age-related differences in a task requiring inferencing may be explained by a combination of the factors of working memory (time and availability of information) and prior knowledge as well as a possible decline in inferencing ability. Prior knowledge is important for both age groups and especially so for older adults. Important implications for designers are to make information available and explicit.

Five ancient shipwrecks have been found in the sea off Croton, in southern Italy, each carrying a marble cargo composed of massive blocks, column shafts, and smaller artifacts. Three of them were located while surveying the seafloor with a multibeam sonar, and the remaining two with the help of divers, in the summers of 2005 and 2006. Two of the marble carriers are located in the bay of Punta Scifo and, therefore, are identified as the Punta Scifo A and Punta Scifo B shipwrecks, the remaining three take their names from the closest promontories: Punta Cicala, Capo Cimiti, and Capo Bianco. The Punta Scifo A shipwreck was chosen as the main focus of this work because it contains a unique assemblage of marble artifacts; including 13 basins, 15 stands decorated with lions’ paws, 16 column shafts, 14 blocks, 6 statue pedestals, and one statuette of Eros and Psyche. Moreover, because the original discovery dates back to 1908, and in 1915 salvors raised 150 tons of marble artifacts, much information was in danger of being lost. Consular inscriptions on the Punta Scifo A’s marble blocks and column shafts date the shipwreck to the early third century A.D. The merchantman was ca. 30 m long and 10 m wide, with a cargo of marble items weighting ca. 200 tons. The merchantman was loaded with its marble cargo in Asia Minor: all the items carried on board came from the quarries of Proconnesus and Docimium. The most likely point of departure was either Epheus or Miletus. While sailing toward the Strait of Messina, it is likely that a Grecale or Levante storm broke, and the helmsman was forced to look for shelter in the protected bay of Punta Scifo. Due to a change in wind direction a southerly Scirocco storm caused the ship to sink. Since the entire coastline south of Croton is totally unprotected to the south, there was no way for the crew to save their ship. Where the Punta Scifo A merchantman was destined remains unknown, although Rome appears to be a likely candidate.

Northern bobwhite (Colinus virginianus) populations are irruptive along their western periphery. Previous research has failed to identify the factors associated with these irruptions, but precipitation is often assumed to be a primary causal factor. I hypothesize that the mechanism may involve demographic variables, specifically that birds entering their second breeding season are more successful than subadult breeders. A better understanding of age-specific survival and productivity in quail populations may be beneficial if managing for a population with an older age structure could ameliorate the irruptive cycles. Radiotagged bobwhites (n > 100 each year; approximately equal numbers (25) of each age-sex class) were followed throughout the breeding season (Mar. – Aug.) in 2003 and 2004 in Fisher County, Texas. Survival, nesting attempts, hatch rate, and clutch size were monitored. Probability of survival of radiotagged birds during the breeding season was S = 0.465 and S = 0.395 in 2003 and 2004, respectively; survival was similar among all age-sex classes. Nest success was greater in 2004 (52.4%, n = 42) than 2003 (28.6%, n = 35) and the 2004 breeding season was at least 20 days longer, likely due to more summer rainfall and cooler temperatures. Nest success was similar among adult and subadult hens in 2003 (4 of 21 adult nests, 6 of 14 subadult nests) and 2004 (16 of 28 adult nests, 7 of 14 subadult nests). Nest initiation was similar in 2003 (0.84 nests/adult hen vs. 0.61 nests/subadult hen), but adults initiated more nests than subadults in 2004 (1.04 nests/adult hen vs. 0.58 nests/subadult hen). Adult hens initiated 12 of 15 renesting attempts observed. Nest initiation dates and nest site selection were similar between adults and subadults. The adult:subadult ratios for 2003 and 2004 were 1:3.0 and 1:1.3 (n = 426 and n = 224, respectively). Extrapolating from the sample population, subadults contributed approximately 84% of the chicks fledged in 2003 but only 37% in 2004, while adults contributed 16% and 63% in 2003 and 2004, respectively. Results from this study suggest that if covey demographics are a component of bobwhite irruptions, the mechanism is most likely due to greater renesting effort by adult hens.
