The influence of an integrated PBL format on geography students’ perceptions of their self-directedness in learning

Problem-based learning can be implemented in South African geography teacher education to foster geography students’ self-directed learning skills. The purpose of this longitudinal case study was to determine B.Ed. geography students’ (n = 45) perceptions of their self-directedness in learning in integrated problem-based learning experiences over a three-year period. The study used quantitative and qualitative research methods based on questionnaire application and semi-structured focus group interviews. The students completed a standardized questionnaire at regular intervals with the implementation of integrated problem-based learning experiences in geography modules over a three-year period. Focus group interviews with participants (n = 8) were employed to get a deeper understanding of the results of quantitative data. The results indicated that the geography students’ self-directed learning scores increased with the implementation of an integrated problem-based learning format in geography over the three-year period. The students who measured average, below average and low levels of self-directed learning at the beginning of the study had the highest increase in self-directed learning scores over the three years. The female students’ perceptions of their self-directedness in learning had higher increases in their self-directed learning scores after the problem-based learning interventions when compared to the male students.     

The effect of population variation on the accuracy of sex estimates derived from basal occipital discriminant functions

Multiple discriminant functions that estimate sex from the dimensions of the basal occipital have been published. However, as there is limited exploration of basal dimension variation between groups, the accuracy of these functions when applied to archaeological material is unknown. This study compares basal dimensions between four known sex-at-death post-medieval European samples and explores how metric differences impact on the accuracy of sex assessment discriminant functions. Published data from St Bride’s, London (n = 146) and the Georges Olivier collection, Paris (n = 68) were compared with new data from the eighteenth to nineteenth century Dutch Middenbeemster sample (n = 74) and the early twentieth century Rainer sample, Romania (n = 282) using independent t tests. The Middenbeemster and Rainer data were substituted into six published discriminant functions derived from the St Bride’s and the Georges Olivier samples, and the results were compared to their known sex. Multiple statistically significant differences were found between the four groups. Of the six discriminant functions tested, five failed to reach the published accuracy and fell below chance. In addition, even where the samples were statistically comparable in means, trends for difference also impacted the accuracy of discriminant functions. Enough variation in basal occipital dimensions existed in the European groups to decrease the accuracy of sex estimation discriminant functions to unusable. Possible inter-observer error, varying genetic, socioeconomic, and geographical factors are likely causes of dimension variation. This research further highlights the dangers of using sex estimation discriminant functions on samples that differ to the original derivative population and demonstrates the need for more rigorous testing.     

The creative industries: conflict or collaboration? An analysis of the perspectives from which policymakers,art organizations and creative organizations in the creative industries are acting

This paper compares and contrasts the instruments and values formulated in the creative industries policies of three peripheral municipalities of between 150,000 and 220,000 inhabitants in the Netherlands (Groningen, Arnhem and Eindhoven) with the needs of the creative industries itself. The needs of the creative industries have been empirically researched by conducting an online survey (n = 556) and twelve in-depth interviews with professionals from different types of organizations in the creative industries. In this study, the theoretical framework of Boltanski, Thévenot and Chiapello is used in the analysis of policy documents, the outcomes of the online survey, and the in-depth interviews in order to uncover differences and similarities in perspectives from which art organizations, creative organizations and policymakers are acting in the creative industries.     

‘The Tent’s Big Enough for Everyone’: online slash fiction as a site for activism and change

This article draws on a piece of wide-scale mixed-methods research (n = 429) that examines how women who write and read male/male erotica feel their involvement with the genre has affected their views on gender and sexuality and their political engagement with gay rights issues. Previous work has looked at how online slashfic communities might provide a safe space for exploring gender performance and sexuality, while other researchers have observed a tension between those who identify as queer themselves and those who only ‘play at queerness’ exclusively within the online environment. However, much of this work has examined the theoretical positioning of such forums as transgressive and/or political. Far fewer pieces have attempted to engage with the women who frequent such sites to ask them about whether their involvement in these online spaces has affected their attitudes and behaviours. This study looks not only at the ways in which online m/m fandoms can act as a safe space for women to explore their sexualities and gender identities, but whether and how these insights connect to women’s real-world lives. Data presented here shows a strong consensus among participants that involvement with explicit slash communities has had a positive effect on their lives, as well as contributing to beneficial changes in their knowledge, attitudes, and practices with regards to LGBTQ+ issues. Overall, slash is seen as a medium which can create better allies, encourage cross-identification, and bring about positive personal changes. To this extent, I argue that explicit online slash sites can act as heterotopias.     

Archaeological Amerindian and Eskimo cranioskeletal size variation along coastal western North America: relation to climate,the reconstructed diet high in marine animal foods,and demographic stress

A quantitative bioenvironmental study of cranioskeletal size has been made of a latitude-ordered sequence of 14 series of adult skeleton sets (N=305): the archaeological remains of aboriginal maritime peoples inhabiting the west coast of North America between southern California and the Arctic. Of eight osteometric parameters of cranioskeletal size developed, the most important are partial skeleton volume (PSK) and cranial capacity (CC); and the principal bone-affecting environmental factors are the northerly climate (CLIM2c), the reconstructed diet deficient in calcium and overabundant in animal foods and vitamin D (DIET3c), and demographic stress (DSg). Prior research has demonstrated that cranioskeletal size increases with geographical latitude and decreases under dietary calcioprivation and unphysiologically high birth rates. Upon linear multifactorial statistical analysis our main finding, limited to the Amerindian subsequence (n=11 series) from the Santa Barbara Channel, the San Francisco Bay Region and the Northwest Coast, is that PSK and CC vary in direct proportion to CLIM2c, and inversely with DIET3c and DSg. Controlling for the latter two osteoantitrophic factors, coastal Amerindian female PSK rises by 9% between 34 and 54°N latitude, CC by 5%; and the male incremental rates are somewhat higher, 13 and 10%, respectively. This newly discovered climate-dependent race cline, an example of Bergmann's Rule, is interpreted as factual evidence of a mid-Wisconsin or earlier arrival date for the first Palaeoindians. Cranioskeletal size of the very small (n=3 series) Western Eskimo subsequence approximates the northernmost values of the coastal Amerindian distribution. © 1998 John Wiley & Sons, Ltd.     

Transformative learning in community college human geography: a mixed methods study

ABSTRACT

The study explores the extent to which transformative learning occurs using quantitative and qualitative methods in a human geography course (N = 35) and explores student affect in relation to the learning environment. We used the eight-scale Transformative Learning Environments Survey (TLES) instrument for the quantitative analysis and an aligned analysis of student reflective work to capture the “voice” of the student as a qualitative approach that provided a rounded perspective of transformative learning. The TLES proved reliable where the sub-scale Alpha reliability ranged from 0.71 to 0.93 and a separate affect scale of Satisfaction was 0.95. The standardized regression coefficient between Satisfaction and the sub-scale of Student-Acting demonstrated the strongest positive association (0.27), followed closely by Disorienting Dilemma-Environment (0.24). The qualitative results supported the quantitative associations in most cases, but not all. The qualitative aspect to this present study offers a deeper look – beyond just statistical outcomes – using students’ own voices to explain their perspectives related to transformative learning.     

Integrating isotopes and documentary evidence: dietary patterns in a late medieval and early modern mining community,Sweden

This study explores the relationship between dietary patterns and social structure in a pre-industrial mining community in Salberget, Sweden c. 1470 to 1600 A.D. using a combination of different research approaches and tools, including archaeology, osteology, bone chemistry and history. The correlation between demographic criteria (sex and age) and archaeological variables (burial type and burial location) shows that Salberget was a highly stratified community. Group diets were investigated through analyses of stable isotopes (carbon, δ ¹³C, and nitrogen, δ ¹⁵N) of bone collagen from a sub-sample of individuals buried at the site (n = 67), interpreted alongside data from human dental lesions and deficiencies, animal bone waste and information on eating habits extracted from the extensive historical documents regarding mining activities at Salberget. These integrated analyses provide a clear association between social status and diet and confirm that social status, and to a lesser extent sex, gender and age, likely governed food choice and opportunity in this diverse community.     

Isotopic anthropology of rural German medieval diet: intra- and inter-population variability

This study investigates the diet of an eleventh century CE parish community located in northwestern Germany. We assessed the isotopic compositions of human (n = 24) and faunal (n = 17) bone collagen (δ ¹³C_col, δ ¹⁵N_col) and human structural carbonate (δ ¹³C_sc) using skeletal material recovered from the Dalheim cemetery. Traditional interpretation of the isotopic data indicates that Dalheim residents likely relied on a C₃ plant-based diet and consumed some terrestrial animal products without evidence of marine resource input in the diet. Bivariate and multivariate models used as an additional means to assess diet indicate minor consumption of C₄ plant foods in this community. The multivariate-isotope model identified regional similarities and differences in C₄ plant/marine food consumption and in dietary protein sources by comparing data from Dalheim with those of other medieval sites from the published literature. We did not observe sex differences in this population but differences in δ ¹⁵N_col suggest that juveniles consumed the lowest trophic level protein.     

Mothers' business,work/life and the politics of ‘mumpreneurship’

Heralded by some as ‘the new feminism’, the new, internationally widespread phenomenon of ‘the mumpreneur’ represents a hotly contested and contestable subject identity. This article explores the debate, arguing that its themes drive to the heart of current issues regarding changing working practices, locations and gender identities in affluent societies. The analyses of women entrepreneurs' views presented here (n = 330) reveal that practitioners are sharply polarised on ‘the mumpreneur’. This article explores these views and progresses research agendas by asking whether such information and communication technology-enabled transformations in working practices (embodied in the figure of the ‘mumpreneur’) have the potential to deliver greater choice for mothers' labour, or whether, conversely, they re-enable iniquitous gender role expectations and arrangements within families.     

What is Geography? Perceptions of first year undergraduates in South Africa

Disciplines such as Geography are well placed to respond to the changing needs of society and the effective application of geographical knowledge to real-world problems. This project surveyed first year Geography undergraduates’ understanding of “What is Geography?”, both before and after an exercise in which geographic topics were identified within recent newspapers. The survey instrument employed was an anonymous, self-administered questionnaire, and was undertaken with first-year undergraduate Geography students at a university in South Africa. Results show that the exercise enabled students (n = 158) to more readily see the application of geographical knowledge to both environmental and social problems that they identified in the newspaper stories. Students also identified that studying Geography may be able to help them increase their skills, employment prospects and earning potential. These findings can help locate the disciplinary concerns and applicability of Geography in post-apartheid South Africa within the wider context of the twenty-first Century world.     

Undertaking a Dissertation from Start to Finish: The Process and Product

Advocates for using a geographic information system (GIS) in education assert that GIS improves student learning. However, studies to clarify the relationship between learning and using GIS are still needed. This study examines the effects of using Web-based GIS maps in place of paper maps on students' geography content knowledge and motivation (self-efficacy) when taking college-level introductory human geography (N = 171). Hierarchical regression analysis shows that using Web-based GIS is positively related to post-test self-efficacy and post-test geography content knowledge.     

GEOGRAPHIC SEPARATION AND PATTERNS OF SOCIAL INTERACTION BETWEEN RESIDENTS OF SENIOR CITIZEN APARTMENT BUILDINGS AND THEIR ADULT CHILDREN

In this study, research questions are formulated to investigate the determinants and consequences of the physical distances separating residents of government-assisted senior citizen apartment (SCA) projects and their adult children. Interview survey data were obtained from residents (n= 97) of three SCAS in suburban Winnipeg, Canada, and geographically matching baseline samples of community residents (n= 105). The analysis involves the use of bivariate statistical inferential tests and multiple regression frameworks. The results disclose that (1) greater parent-child separation distances are registered by SCA residents compared to the community elderly; (2) ‘distance of the most recent residential move’ is the most significant predictor of the intergenerational separation distances recorded by SCA residents; (3) spatial proximity is the most significant predictor of social interaction between SCA residents and their children. It is concluded that the results have important implications for (1) developmental models of elderly migration and (2) policies governing the provision of seniors' housing. Dans cette étude, on s'interroge sur les déterminants et les conséquences des distances physiques qui séparent les reéidents des programmes d'habitation pour personnes âgées (SCA) subventionnés par le gouvernement, et leurs enfants adultes. On a recueilli des données d'enquête en faisant des entrevues avec les résidents (n= 97) de trois SCA dans la banlieue de Winnipeg, Canada, et avec des résidents dans la communauté (n= 105) qui font partie des échantillons de référence appariés géographiquement. Pour analyser les données, on a utilisé des tests d'inférence statistique bivariés et des analyses de régression multiple. Les résultats démontrent les faits suivants: (1) les enfants des résidents des SCA sont séparés de leurs parents par une plus grande distance que les enfants des personnes âgées dans la communauté; (2) ? la distance du plus récent déménagement?est le prédicteur le plus important des distances de séparation intergénérationnelle; (3) la proximité spatiale est le prédicteur le plus significatif de l'interaction sociale entre les résidents des SCA et leurs enfants. Ces résultats comportent des conséquences importantes pour le développement des modèles de migration des personnes âgées, aussi bien que pour les politiques qui régissent le logement pour personnes âgées.     

Pre-Columbian Fishing on the Coast of the Atacama Desert,Northern Chile: An Investigation of Fish Size and Species Distribution Using Otoliths From Camarones Punta Norte and Caleta Vitor

The bountiful marine resources of the northern Chilean coast offset the extreme aridity of the Atacama Desert in pre-Columbian times, underwriting permanent human occupation, and providing the basis for a long tradition of marine subsistence. We analyzed fish otoliths (n = 549) recovered from the sites of Camarones Punta Norte (occupied ca. 7,000–5,000 years ago) and Caleta Vitor (occupied ca. 9,500–300 years ago) to investigate species distribution and changes over time. We also estimated the size of the fish based on relationships between otolith weight and fish total length (TL) obtained from modern samples of the predominant species, Sciaena deliciosa. The estimated size range of S. deliciosa from Caleta Vitor included fish that were significantly larger than those from Camarones Punta Norte, with the maximum TL (970 mm) almost double the modern maximum length documented. The fluctuating abundance of fish species and other marine taxa from Camarones Punta Norte indicates intense but sporadic use of the site over the span of occupation. In contrast, human occupation of the Caleta Vitor estuary is more continuous. Comparisons of the fish assemblages with a nearby contemporaneous site, Quebrada de los Burros in southern Peru, suggest that fishing technologies were similar along this section of the Pacific coast.     

Estimation of Age,Growth and Fishing Season of a Palaeolithic Population of Grayling (Thymallus thymallus) Using Scale Analysis

The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus ¸ has the most easily recognizable scales and is a commonly recovered species from Palaeolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n  = 22), Switzerland (n  = 16), Finland (n  = 20) and Sweden (n  = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The results showed that the archaeological population of grayling is closer to the present Finnish population. Furthermore, the comparison of seasonal growth patterns between current and archaeological European populations demonstrated that graylings were normally captured during the spring at Le Taillis des Coteaux Magdalenian site. This type of approach can be used to understand environmental conditions at a low spatial scale and also to help identify fishing seasons during archaeological periods.

Is the circumference at the nutrient foramen of the tibia of value to sex determination on human osteological collections? Testing a new method

This paper tests the validity of the circumference at the nutrient foramen of the tibia for sex determination on two human osteological collections: the Lisbon Collection of Identified Skeletons (n = 160) and the São Martinho medieval archaeological collection from Leiria, Portugal (n = 57). The methodological approach chosen to conduct the test was the sectioning point method. The overall accuracy (males and females combined) in the Lisbon Collection was 78% and in the São Martinho Collection it reached 90%. In both series, females were more accurately classified than males. This paper advocates the importance of developing and using sample specific methods for sex determination in modern and in archaeological human osteological assemblages.

The Turnover Club: locality and identity in the North Staffordshire practice of turning over ceramic ware

This paper explores a key practice adopted by those local to or from Stoke-on-Trent, and outlines its significance in the wider context of ‘ordinary’ consumption and material cultures, globalisation and local identity. Being a ‘turnover-er’ – someone who always turns over pottery to check whether it is Stoke-on-Trent ware – is an oft practised, but little examined part of the living heritage that connects those with affinity to ‘the Potteries’ (as the region is known) and its ceramic ware. The project set out to explore qualitative accounts of turning over and to gauge its salience and reach as a practice, linking this to broader accounts of material culture, consumption and heritage. We carried out 20 interviews with those who turn over or who have an interest in local ceramics, and an online survey (n = 500) which explored the some of the reasons for turning over. Findings indicate the strong connections established by the practice of turning over to local identity, both inherited and adopted, and further indicates the social salience and emotional attachments to the meanings of local ware.     

Wildlife Visual Imagery: Do Pictures Used to Promote Destinations Online Match On‐site Species Visibility at Two Geographic Destinations?

Diverse photographic images (pictures) are used to promote wildlife tours on the Internet. But what pictures are used and are they likely to accurately reflect what visitors might see, and hence create realistic expectations for tourists? The relative importance of wildlife and the prevalence of iconic species were assessed for pictures on the Internet used by six English tour companies offering wildlife tours to very different destinations: Southern Africa and Australia. These were then compared with the likely visibility of wildlife at the destination. The content of 926 Southern African pictures representing 1316 different subjects, and 228 pictures representing 307 different subjects from Australia were classified into four themes (wildlife, landscapes/vegetation, activities, accommodation). Wildlife, particularly large mammals, was more frequently used for Southern African tours (43%) whereas pictures for Australian tours were often of landscapes (45%). Large, social mammals active during the day and hence highly visible (e.g. elephant, n= 64) were often used, while iconic, but cryptic, species such as koalas (n= 7), Tasmanian devil (n= 1), leopards (n= 12), and black rhinos (n= 2) were seldom used. Therefore, online pictures used for wildlife tours appear to merge well with what tourists are likely to see at the destination, but appear to diverge somewhat from established destination images for these two regions, particularly Australia.     

Public Attitudes toward Official Bilingualism in Canada: Making Sense of Regional and Subregional Variation

ABSTRACT

Pierre Trudeau’s vision of Canada’s cultural policy was situated within a bilingual framework. Canada, so conceived, has “no official culture” and two official languages. Nearly 50 years later, debates regarding the effects and broader significance of this policy combination persist as illustrated by the recent debate about Supreme Court judges. Yet, Canadians’ attitudes about bilingualism have received relatively little scholarly attention. This paper probes the structure and recent evolution of public attitudes toward the general idea of official bilingualism using the Survey on Official Languages (2003) and the Canadian Election Studies (1997–2011). It goes on to investigate regional differences in public support for bilingual Supreme Court judges using a large-scale survey conducted by Vox Pop Labs in 2015 (n = 291, 577). The combination of these data sources offers new insights into the contextual and individual-level determinants of regional differences in public attitudes toward bilingualism policy in Canada.     

The man who never was? The Italian transition and 2008 election

Abstract

The implications for the co-called Italian transition of the 2008 election initially seemed significant – but have since become increasingly uncertain as Berlusconi's conflict of interests has risen higher up the political agenda. This underscores the pertinence of asking about the sense in which the notion of ‘transition’ is actually applicable to the Italian case at all – bearing in mind that it describes a process now supposedly underway for some 17 years; and bearing in mind that its end point can seemingly not be identified (though by definition ‘transition’ implies movement between two points). Discovering if the term applies to the Italian case and if so whether 2008 has brought its conclusion nearer requires exploring if the political protagonists that have emerged from the election as the most significant players – the Popolo della Libertà and the Partito Democratico – have sufficient commonality of view, sufficient desire and sufficient power to complete a process of constitutional overhaul. The evidence suggests that while they have the view and the desire, there are significant limitations on their power. The election might potentially have been a watershed in the so-called Italian transition in the broader sense of system performance, aside from formal constitutional change. Here too, however, the evidence points away from the idea that 2008 represents a real sea change – though the chances seem good that it will come to be perceived as such.     

Mitochondrial DNA diversity in a Transbaikalian Xiongnu population

Xiongnu was a confederation of nomadic pastoral tribes (~200 bc–100 ad) that founded the first nomadic empire in Central Asia. According to archeological and historical data, the tribes played a key role in ethnic and cultural processes in Central Asia and adjacent regions of Eurasia. Genetic studies of the Xiongnu published to date have focused on remains from burial grounds in present-day Mongolia, in the southern part of the ancient Xiongnu area. However, paleoanthropological materials from numerous Xiongnu cemeteries and settlements in Transbaikalia (the southern region of Eastern Siberia, Russia) in the northern part of the Xiongnu Empire have not been examined genetically. Here, we analyzed mitochondrial DNA variation in a Transbaikalian Xiongnu population based on ancient DNA obtained from skeletal remains (n = 18) at four burial grounds to complement available Xiongnu genetic diversity data. We detected 16 mitochondrial DNA haplotypes belonging to seven East Eurasian haplogroups (A, B5, C, D4, G2a, N9a, and Y) in the Transbaikalian Xiongnu series. We observed substantial similarity between Transbaikalian and Mongolian Xiongnu series with respect to main haplogroup composition and frequencies. We observed several mitochondrial DNA clusters (N9a, Y, B5, and A16) and 11 of 16 haplotypes that were previously undetected in the Xiongnu gene pool. We also observed high similarity between the Xiongnu and contemporary indigenous populations of eastern Central Asia, particularly Mongolian-speaking groups. These findings extend our knowledge of Xiongnu genetic diversity.
