Abstract

Purpose

The purpose of this paper is to discuss the technical aspects of using the Edventure Builder platform to create UC San Diego’s scalable, interactive, online library orientation activity, which was designed for the university’s new First Year Experience program.

Design/methodology/approach

This paper examines a case study using a successive approximation model for the build process of a mobile library scavenger hunt.

Findings

The Edventure Builder software is intuitive, scalable and provides a variety of options to users, including flexibility in question format, a WYSIWYG interface, and branching logic. The main limitation is that analytics is still in beta testing and users must request that data be sent in an Excel spreadsheet via e-mail.

Originality/value

This paper is of interest to information professionals who would like to create a mobile library orientation activity using the Edventure Builder platform.

Abstract

Purpose

This chapter uses Goffman’s concept of total institutions in a comparative case study approach to explore the role of psychotropic drugs in the process of transinstitutionalization.

Methodology/approach

This chapter interprets psychotropic drug use across four institutionalized contexts in the United States: the active-duty U.S. military, nursing homes and long-term care facilities, state and federal prisons, and the child welfare system.

Findings

This chapter documents a major unintended consequence of transinstitutionalization – the questionable distribution of psychotropics among vulnerable populations. The patterns of psychotropic use we synthesize suggest that total institutions are engaging in ethically and medically questionable practices and that psychotropics are being used to serve the bureaucratic imperatives for social control in the era of transinstitutionalization.

Practical implications

Psychotropic prescribing practices require close surveillance and increased scrutiny in institutional settings in the United States. The flows of mentally ill people through a vast network of total institutions raises questions about the wisdom and unintended consequences of psychotropic distribution to vulnerable populations, despite health policy makers’ efforts regulating their distribution. Medical sociologists must examine trans-institutional power arrangements that converge around the mental health of vulnerable groups.

Originality/value

This is the first synthesis and interpretive review of psychotropic use patterns across institutional systems in the United States. This chapter will be of value to medical sociologists, mental health professionals and administrators, pharmacologists, health system pharmacists, and sociological theorists.

Abstract

A novel approach to many‐body quantum transport theory which emphasize the role of localized orbitals, and their lattice Fourier transforms, as dynamical basis states is given. The formalism allows for the calculations of particle quantum trajectories, describing individual elementary space and time‐dependent events in quantum processes. It is demonstrated that the particle quantum trajectories exhibit behavior quite identical to that of classical particles acted upon by a new “effective quantum force”. The present technique for calculating the quantum force can be applied to a procedure for incorporating space and time‐dependent quantum tunneling in Selfconsistent Ensembe Particle Monte Carlo (SEPMC) technique for multidimensional device analysis.

Abstract

Purpose

The purpose of this paper is to develop a new method for biomolecular recognition based on light scattering of ZnS:Mn nano‐particle functionalised with biotin.

Design/methodology/approach

ZnS:Mn nano‐particles was successfully synthesised from quaternary water‐in‐oil micro‐emulsion system. The addition of biotin and the subsequent specific binding events alter the dielectric environment of the nano‐particle, resulting in a spectral shift of the particle plasmon resonance. Cyclohexane was used as oil, Triten X‐100 as surfactant, n‐hexanol as a co‐surfactant and mercaptoethanol for the best linking of biological part to nano‐particle. Measurement of the content of avidin was achieved by detecting the Department of Biomedical Engineering change in the excited emission. For qualitative and quantitative analyses of this product, scanning electron microscopy, transmission electron microscopy, energy dispersive X‐ray spectroscopy and spectrograph techniques were used.

Findings

It was observed that with reducing particle size, emission shifted to the lower wave lengths. In addition, with conjugation between avidin and biotin by mercaptoethanol in biologic media, spectral emission decreased.

Practical implications

The method developed could be utilised for synthesis of a variety of ZnS:Mn nano‐particles for a wide range of diagnostic applications.

Originality/value

The method for biomolecular recognition based on light scattering of ZnS:Mn nano‐particle functionalised with biotin developed was novel.

Abstract

Purpose

The incompatibility of natural fibers with polymer matrices is one of the key obstacles restricting their use in polymer composites. The interfacial connection between the fibers and the matrix was weak resulting in a lack of mechanical properties in the composites. Chemical treatments are often used to change the surface features of plant fibers, yet these treatments have significant drawbacks such as using substantial amounts of liquid and chemicals. Plasma modification has recently become very popular as a viable option as it is easy, dry, ecologically friendly, time-saving and reduces energy consumption. This paper aims to explore plasma treatment for improving the surface adhesion characteristics of sisal fibers (SFs) without compromising the mechanical attributes of the fiber.

Design/methodology/approach

A cold glow discharge plasma (CGDP) modification using N2 gas at varied power densities of 80 W and 120 W for 0.5 h was conducted to improve the surface morphology and interfacial compatibility of SF. The mechanical characteristics of unmodified and CGDP-modified SF-reinforced epoxy composite (SFREC) were examined as per the American Society for Testing and Materials standards.

Findings

The cold glow discharge nitrogen plasma treatment of SF at 120 W (30 min) enhanced the SFREC by nearly 122.75% superior interlaminar shear strength, 71.09% greater flexural strength, 84.22% higher tensile strength and 109.74% higher elongation. The combination of improved surface roughness and more effective lignocellulosic exposure has been responsible for the increase in the mechanical characteristics of treated composites. The development of hydrophobicity in the SF had been induced by CGDP N2 modification and enhanced the size of crystals and crystalline structure by removing some unwanted constituents of the SF and etching the smooth lignin-rich surface layer of the SF particularly revealed via FTIR and XRD.

Research limitations/implications

Chemical and physical treatments have been identified as the most efficient ways of treating the fiber surface. However, the huge amounts of liquids and chemicals needed in chemical methods and their exorbitant performance in terms of energy expenditure have limited their applicability in the past decades. The use of appropriate cohesion in addition to stimulating the biopolymer texture without changing its bulk polymer properties leads to the formation and establishment of plasma surface treatments that offer a unified, repeatable, cost-effective and environmentally benign replacement.

Originality/value

The authors are sure that this technology will be adopted by the polymer industry, aerospace, automotive and related sectors in the future.

Abstract

Analyzing how the post-Soviet transition interacts with the crisis of market finance exhibits a new “greed-based economic system” in the making. Asset grabbing is at its core and hinders capital accumulation. All the various privatization schemes have triggered off asset grabbing, asset stripping, and asset tunneling. A global contagion of such behavior has spread the power and cohesion of managers/shareholders (oligarchs) worldwide. Financial asset grabbing is less straightforward, though much widespread, and operates in financial markets through new financial products, securitization, firms buying their own shares, hedge funds, stock price manipulation, short selling, and the distribution of stock options.Shadow banking, and more generally a global informal economy, results from grabbing strategies in financial markets that breach the formal rules of capitalism. In alleviating and circumventing the rules, the oligarchy paves the way for economic malpractices and crime, calling capitalist laws into question.In such context, systemic greed underlies unconstrained maximization of relative wealth, for which asset grabbing is a rational means, in a winner-take-all economy. At the present stage of our research, a greed-based economy cannot yet be theoretically defined as a transition either to a new phase of capitalism or to another different system.

Abstract

Purpose

The imposition of the Sarbanes Oxley (SOX) Act and the NYSE/NASDAQ regulations boosted the proportion of independent directors serving on corporate boards. For certain firms, increasing the number of independent directors may impose costs that exceed the benefits. The purpose of this paper is to examine the implications of increased independence following SOX, relative to the pre-SOX board independence benchmark, on managerial authority and entrenchment within the firm.

Design/methodology/approach

Data are collected from COMPUSTAT, ExecuComp, and RiskMetrics. Data are divided into two periods, pre-SOX (1996-2001) and post-SOX (2002-2006). The focus is on the sub-group of firms who were not complying with the board independence requirement prior to SOX and became compliant afterwards. Various regressions are employed to assess the implications of increased independence following SOX on managerial authority and entrenchment.

Findings

The appreciation in board independence post-SOX significantly inflates both managerial compensation and the likelihood of CEO duality. Also, there is a positive association between board independence and managerial entrenchment during both the pre- and post-SOX periods. Imposed board composition requirements diminished board monitoring efficiency and boosted the CEO dominance and control over the firm.

Originality/value

This research adds to the extant literature investigating the implications of SOX on internal monitoring and governance. The results are based on an off-equilibrium phenomenon in which companies were obliged to alter their endogenously determined board structure. Thus, regulations to improve governance could backfire as the CEO might abuse them to extract private benefits.

Abstract

Economic ideas are the product of contemplation, but also of our economic lives. In the history of ideas, Gérard Debreu’s shining book of 1959, Theory of Value, represents the pinnacle of purity in contemplating economic life. Rather than contextualizing this oeuvre through his intellectual life, as is usually done, this essay describes his axiomatic analysis by contextualizing it through his economic life. What do we learn about Debreu’s axioms on consumption when thinking of his own consumption? What do we learn about his theory of value when thinking of his own values? Historiographically, this approach permits the use of a widely neglected source in the history of economics: anecdotes. Epistemologically, blending axioms and anecdotes offers a description of how axioms regulate an economic discourse. Finally, this essay offers a language for the material dimensions of economic life that are so underexposed in Debreu’s own work.

Abstract

Purpose

The purpose of this paper is to investigate the competency models used by organizations to assess the strategic thinking ability of their leaders, managers, and other employees.

Design/methodology/approach

A basic interpretive study was conducted with human resource executives across a broad range of large organizations. Participants were interviewed, and competency models in use were shared, reviewed, and discussed. The model development process was also explored in depth. Findings were verified via member checks and triangulation.

Findings

Models in use either identify strategic thinking as a stand-alone competency, or embed it under three different areas. Most cover one or more executive levels, stating varying expectations for strategic thinking by job title or level, or differentiating strategic thinking performance levels. The models include descriptions of strategic thinking behaviors that cross seven categories of strategy development, implementation, and organizational alignment.

Research limitations/implications

The study provides indications of potential generalizations that should be considered with more organizations across sectors.

Practical implications

The findings provide practitioners with format and content examples to enhance the assessment of strategic thinking in existing competency models, as well as process considerations for model development/revision. The findings also identify how competency model components are used across the spectrum of talent management activities.

Originality/value

The study fills a gap in the literature by providing empirically based identification of the strategic thinking behaviors organizations consider essential competencies and how they are assessed. In so doing, the study provides a glimpse of how strategic thinking is used in practice and across a range of strategic management activities. In addition, the study links strategic thinking to the competency development literature, illustrating details of competency model development for strategic thinking, and identifying opportunities for related theory development in both domains.
