This study isolates the effect of immersion on players’ learning in a virtual reality (VR)-based game about cellular biology by comparing two versions of the game with the same level of interactivityand different levels of immersion. The authors identify immersion and additional interactivity as two key affordances of VR as a learning tool. A number of research studies compare VR with two-dimensional or minimally interactive media; this study focuses on the effect of immersion as a result of the head mounted display (HMD).

In the game, players diagnose a cell by exploring a virtual cell and search for clues that indicate one of five possible types of cystic fibrosis. Fifty-one adults completed all aspects of the study. Players took pre and post assessments and drew pictures of cells and translation before and after the game. Players were randomly assigned to play the game with the HMD (stereoscopic view) or without the headset (non-stereoscopic view). Players were interviewed about their drawings and experiences at the end of the session.

Players in both groups improved in their knowledge of the cell environment and the process of translation. Players who experienced the immersive stereoscopic view had a more positive learning effect in the content assessment, and stronger improvement in their mental models of the process of translation between pre- and post-drawings compared to players who played the two-dimensional game.

This study suggests that immersion alone has a positive effect on conceptual understanding, especially in helping learners understand spatial environments and processes. These findings set the stage for a new wave of research on learning in immersive environments; research that moves beyond determining whether immersive media correlate with more learning, toward a focus on the types of learning outcomes that are best supported by immersive media.

The purpose of this paper is twofold: first, it seeks to trace the origins of the various strands of postmodernism within German philosophic idealism; traditions of thought which placed emphasis – like postmodernism – on a subjective understanding of evidence and a supposed capacity of human consciousness to continually move beyond the bounds imposed by social convention and being; second, this paper states that postmodernism, rooted as it is in philosophic idealism, is methodologically and conceptually constrained. Its emphasis on consciousness and will marginalize its capacity to make meaningful contributions in areas such as economics, and the wider trends in human history.

This paper is theoretical. It seeks to locate conflicting methodologies – most particularly those relating to postmodernism, positivism and philosophical realism – within the traditions of thought that have emerged since the enlightenment.

Postmodernism is rooted in philosophical idealism. As such, it places emphasis on consciousness, identity and being. The essential problem with postmodernism, this paper argues, is not this emphasis. These are legitimate areas of inquiry. Rather, the central problem with postmodernist-informed research is found in the limited range of methodological and conceptual tools in its kitbag.

Despite the growing influence of postmodernism in its various shades within academia, few of its proponents and critics trace its philosophic origins. In doing so this paper highlights the strengths and limitations of not only postmodernism but also its polar opposite, positivism.

This study aims to suggest that firms and stock market investors are more sensitive about inventory leanness when industry information technology (IT) usage is high. First, when industry IT usage is high, a firm's inventory leanness is more responsive to information inputs (cash holding and sales efficiency). Second, when industry IT usage is high, the price-to-earnings ratio (indicative of stock market investors' willingness to pay a premium) is more sensitive to the firm's inventory leanness.

This study highlights the contextual role of industry IT usage during the 1998–2009 lost decade (wherein the steepest falls in manufacturing jobs happened in the USA).

The results highlight the significant contextual role of industry IT usage. In manufacturing industry sectors with high IT usage, (1) inventory levels of firms are more responsive to information inputs and (2) stock market investors have greater appreciation for inventory leanness.

The lost decade, 1998–2009, was a difficult period for the manufacturing industry. Nonetheless, there was variation in stock market valuations of manufacturing firms, with many firms outperforming others. Stock market investors were sensitive to inventory leanness. Firms that positively impressed stock market investors were strategically positioned in high IT usage industry sectors and prioritized inventory leanness. Further, their inventories were sensitive to information inputs – their inventories were leaner in response to improved sales-efficiency and/or shortage in cash.

This chapter reconsiders commonly held views on the ownership and management of private property, contrasting capitalist and simple property, particularly in relation to how a firm shareholder governance model has shaped society. This consideration is motivated by the scale and scope of the modern global crisis, which has combined financial, economic, social and cultural dimensions to produce world disenchantment.

By contrasting an exchange value standpoint with a use value perspective, this chapter explicates current conditions in which neither the state nor the market prevail in organising economic activity (i.e. cooperative forms of governance and community-created brand value).

This chapter offers recommendations related to formalised conditions for collective action and definitions of common guiding principles that can facilitate new expressions of the principles of coordination. Such behaviours can support the development of common resources, which then should lead to a re-appropriation of the world.

It is necessary to think of enterprises outside a company or firm context when reflecting on the end purpose and means of collective, citizen action. From a methodological standpoint, current approaches or studies that view an enterprise as an organisation, without differentiating it from a company, create a deadlock in relation to entrepreneurial collective action. The absence of a legal definition of enterprise reduces understanding and evaluations of its performance to simply the performance by a company. The implicit shift thus facilitates the assimilation of one with the other, in a funnel effect that reduces collective projects to the sole projects of capital providers.

Because forsaking society as it stands is a radical response, this historical moment makes it necessary to revisit the ideals on which modern societies build, including the philosophy of freedom for all. This utopian concept has produced an ideology that is limited by capitalist notions of private property.

Research has documented how white teachers often fall short of their anti-racist intentions. However, much of this research is done with preservice teachers or teachers across disciplines. The authors investigate stories in which white English teachers who teach substantial proportions of black students and who self-reported anti-racist goals nevertheless fell short of those goals. The purpose of the study is to understand the tensions between racial liberalism and racial literacy in their pedagogy.

The authors snowball sampled 12 veteran white high school English teachers (3–27 years’ experience) who taught in schools with substantial proportions of black students. The authors used a two-stage interview process to narrow the sample to 7 teachers who confirmed their anti-racist intentions and who wrote narratives of moments when they tried to be anti-racist, but the lesson failed in some way. The authors used a three-stage narrative analysis to analyze how racial liberalism and racial literacy were reflected in the narratives.

The veteran English teachers, despite their anti-racist intentions, told narratives that reflected racial liberalism, portraying racism as an individual and interpersonal phenomenon. Some narratives showed teachers who had taken steps toward racial literacy, but no narratives showed a fully developed sense of racial literacy, portraying the layers of institutional and structural racism in English education.

The sample suggests that veteran white English teachers are subject to similar limited racial literacies as novice teachers. While the authors found glimmers of racial literacy, they still note the work necessary to equip veteran English teachers with the racial literacies necessary for anti-racist instruction. The authors propose directions for teacher education, systemic support and professional development.

The following list is a first attempt to catalogue and describe systematically the British Museum's extensive holdings of early opera librettos and related plays. The great importance of these unpretentious booklets as supplementary and, more often than not, even primary sources for the history and bibliography of dramatic music, besides or instead of the scores, was already clearly recognized in the eighteenth century by Dr. Burney and other scholars. But it is only since 1914, the year in which O. G. T. Sonneck's Library of Congress Catalogue of opera librettos printed before 1800 appeared, that their documentary value could to any greater extent be put to general use in international musicological research. A similar bibliography of the British Museum librettos, while naturally duplicating many Washington entries, would produce a great number of additional tides, not a few of them otherwise unrecorded; it would provide the musical scholar with the key to a collection unequalled elsewhere in Europe, which owing to the peculiar nature of the material is not easily accessible by means of the General Catalogue.

This chapter argues that Marx's definition of “accumulation of capital” is sufficiently ambiguous to lead to troublesome conceptions after his death. It is held that Lenin moved conceptualization in a misleading direction by moving accumulation of capital away from social relations of production. Luxemburg's criticism of Marx's schemes of extended reproduction, on the other hand, is very helpful in moving back towards an emphasis on class relations. To conclude, a definition is offered: accumulation of capital as increase of wage-labor with its associated constant capital. An appendix provides the first English translation of Lenin's marginal notes on Luxemburg's book.

The authors propose a semiparametric approach for testing independence between two infinite-order cointegrated vector autoregressive series (IVAR(∞)). The procedures considered can be viewed as extensions of classical methods proposed by Haugh (1976, JASA) and Hong (1996b, Biometrika) for testing independence between stationary univariate time series. The tests are based on the residuals of long autoregressions, hence allowing for computational simplicity, weak assumptions on the form of the underlying process, and a direct interpretation of the results in terms of innovations (or shocks). The test statistics are standardized versions of the sum of weighted squares of residual cross-correlation matrices. The weights depend on a kernel function and a truncation parameter. Multivariate portmanteau statistics can be viewed as a special case of our procedure based on the truncated uniform kernel. The asymptotic distributions of the test statistics under the null hypothesis are derived, and consistency is established against fixed alternatives of serial cross-correlation of unknown form. A simulation study is presented which indicates that the proposed tests have good size and power properties in finite samples.
