Active learning is increasingly promoted within institutions of higher education to assist students develop higher order thinking and link knowledge to meaning. In this paper, the authors evaluate the use of weekly online quizzes based on prescribed preparatory material as a tool to incentivize preparatory reading in order to enable and encourage active learning. The study is based on mixed data sources, including three years of student-evaluation data, to understand student perceptions of the role and value of online quizzes. The study shows a high level of student engagement with the quizzes and positive assessment of their role in encouraging the completion of prescribed reading. Online quizzes were found to be an effective mechanism for incentivizing student completion of preparatory work, enhancing active learning (such as through in-class discussions), and were relatively time efficient from the perspective of the educator.  相似文献

The arrival of the term Geographical Information System (GIS) in the 1960s soon created a demand for training and education in the use of this specialist hardware and software. Initially the main focus was on training people to use GIS, formal named degree programmes leading to postgraduate and undergraduate qualifications arrived later. This paper explores the changing landscape of U.K. degree level GIS education drawing on contemporary information from Higher Education Institution websites and a case study of the first single honours degree in GIS in Europe. The paper identifies a rise and fall in the number of named undergraduate “GIS” degrees since the late 1980s sandwiched between the continuation and development of postgraduate qualifications. In parallel with this trend the teaching and learning of GIS skills has emerged as a core component of undergraduate degree programmes with “Geography” in their title and in national school and degree level benchmarking statements for the discipline.  相似文献

In Israel and Palestine, map-making practices were always entangled with contradictive spatial identities and imbalanced power resources. Although an Israeli narrative has largely dominated the ‘cartographic battlefield’, the latest chapter of this story has not been written yet: collaborative forms of web 2.0 cartographies have restructured power relations in mapping practices and challenged traditional monopolies on map and spatial data production. Thus, we can expect web 2.0 cartographies to be a ‘game changer’ for cartography in Palestine and Israel. In this paper, I review this assumption with the popular example of OpenStreetMap (OSM). Following a mixed methods approach, I comparatively analyze the genesis of OSM in Israel and Palestine. Although nationalist motives do not play a significant role on either side, it turns out that the project is dominated by Israeli and international mappers, whereas Palestinians have hardly contributed to OSM. As a result, social fragmentations and imbalances between Israel and Palestine are largely reproduced through OSM data. Discussing the low involvement of Palestinians, I argue that OSM's ground truth paradigm might be a watershed for participation. Presumably, the project's data are less meaningful in some local contexts than in others. Moreover, the seemingly apolitical approach to map only ‘facts on the ground’ reaffirms present spatio-social order and thus the power relations behind it. Within a Palestinian narrative, however, many aspects of the factual material space might appear not as neutral physical objects but as results of suppression, in which case, any ‘accurate’ spatial representation, such as OSM, becomes objectionable.  相似文献

Many questions remain about the effects of digital media use on citizens’ political engagement. This article argues that this is because such effects depend on the context in which digital media are used. Its findings are based on two cross-sectional sets from the 2010 and 2013 Australian Election Study and show that (1) political resources played different moderating roles in the association between digital media and offline participation, and (2) such a moderating role depended on different campaign contexts in the two elections, with context affecting political efficacy. The findings confirm that campaign context can function as leverage in motivating online news consumption and political participation, thereby emphasising the importance of political contexts in media use and political behaviour.  相似文献

Monitoring is deemed crucial for the incentivization of a decentralized organization, but its function relies on information transparency between the central authority and the delegated individuals. We test this hypothesis by considering changes in the fiscal behavior of Chinese county governments following an exogenous fiscal reform in 2004/2005 that removed information obstacles between provinces and counties. Employing data on 590 Chinese counties from 2000 to 2009, we find that counties in the reform provinces adopt a more proactive fiscal policy after the reform, suggesting that they become more incentivized in the political competition for economic growth. Such effects are stronger in counties with fewer competing peers and counties with either high or low ranks in the records of economic growth among peers. The increase in counties' productive spending leads to higher economic growth in later years.  相似文献

Information and communication technologies (ICTs) are often cited as an important factor in firm location decisions. This is especially true for firms engaged in information intensive activities and those that have a strong need for advanced services such as broadband. Despite the suggested importance of these technologies, quantitative work evaluating the link between firm location and broadband provision is sparse and existing knowledge remains largely theoretical and speculative. However, theoretical evaluations of the impact of ICTs on firm location do provide a foundation for quantitative analyses of this relationship and may be grouped into three schools of thought: the deconcentration school, the concentration school, and the heterogeneous effects school. The predictions made by these three schools of thought will be analysed in an exploratory context to better understand the relationship between firm location and ICTs, with a focus on broadband service provision. A combination of basic spatial statistical analytical tools and geographic information systems (GIS) will be used in an exploratory spatial data analysis framework to evaluate the relationship between firm location and broadband provision trends from 1999 to 2004 in the state of Ohio. Results suggest that changes in broadband provision have no relationship with changes in firm location. However, a disaggregated, firm level analysis of this relationship does provide statistically significant results for a subset of industrial sectors. Firm size is also found to impact the correlation between firm presence and broadband provision. These results suggest that firm size and industry are perhaps critical components in determining the relative importance of ICTs, such as broadband, in firm location decisions.  相似文献

This paper situates the international satellite industry within three lines of contemporary geographic thought. Second, it reviews the industry's Cold War origins. Third, it explains changing international regulatory structures of satellites, particularly Intelsat, which control access to and use of the technology. Fourth, it summarises the changing role of satellites in the post‐Cold War era, including the impacts of deregulation, rising competition between Intelsat and national and commercial providers, and the heated rivalry between satellites and fibre optic carriers. Throughout, it emphasises the ways in which terrestrial power relations alter access and applications to this sector.  相似文献

This paper considers the idea that technical information exchange in the context of time‐based‐competition encourages buyer‐supplier proximity and local production linkages. The relevance of this idea was tested in a study of 11 subsidiaries of multinational microcomputer assemblers operating in Ireland and Scotland. We show that the assembly plants sourced the vast majority of inputs from regions outside Ireland and Britain and where we find regional linkages, proximity was generally not driven by considerations related to information exchange. Part of the explanation lies in the fact that the European operations played a limited role in technological co‐ordination with suppliers. Another reason is that much of the technical information exchange in the industry is of a relatively limited intensity requiring low levels of face‐to‐face contact.  相似文献

Abstract

This article argues that the essentialist and the constructivist positions within theories of ethnicity are in fact compatible if one introduces a concept here called “internalized fluid capacities”, connoting that which is inherently (genetically) dispositional – and in that sense biologically “anticipated” – but which remains to be developed into observable social characteristics through sociocultural impact. This perspective is based on the genetic capacity to mold or “instruct” the development of an organism from its embryonic state and onwards by using prior stages as points of departure for further instructions. In this way, certain fluid capacities become imprinted in individuals and collectivities through reinforcing interaction with the ambient society. These capacities may then harden and develop into apparent “essentials”, forming a group's collective self-image. The article concludes with the suggestion that this explanatory model can be usefully applied to the debate around Swedish governmental definitions of Saamihood.  相似文献

For five decades it has been generally accepted that reserpine, an antihypertensive and antipsychotic drug, causes depression. The discovery that reserpine depletes brain monoamines was an important factor in the development of the monoamine hypothesis of depression, and it continues to be widely cited in support of this hypothesis. The present paper argues that, contrary to prevailing belief, reserpine is not depressogenic. The reason for perpetuation of this myth is reluctance to discard the monoamine hypothesis. This hypothesis ushered the modern biochemical paradigm into psychiatry and is still of great importance. It serves as a heuristic to guide research, it enhances psychiatry’s prestige, and it helps to validate and promote drug therapy for depression and other mental disorders.  相似文献
