Implementation of innovative technology in organizations is often fraught with challenges. Past literature on mindfulness suggests that mindful implementation of innovative solutions facilitates success and enhances effectiveness for the organization. Integrating insights from the mindfulness and stakeholder perspectives, we present and analyze a longitudinal case study of Radio Frequency Identification (RFID) implementation at YCH Group, a leading logistics provider in the Asia-Pacific region. Our objectives are to examine key attributes of mindfulness as well as identify specific organizational routines that fostered mindfulness at YCH that ultimately paved the way for effective implementation of RFID technology. Important lessons can be learnt from how YCH instituted organizational routines that enabled them to mindfully implement RFID, by explicitly considering both internal and external stakeholders

A Newsvendor Model with Initial Inventory and Two Salvage Opportunities

Mots clés : Newsvendor model, Initial inventory, Lost sales, Salvage opportunities, Concave optimisation and threshold levels


In this paper, we develop an extension of the newsvendor model with initial inventory. In addition to the usual quantity ordered at the beginning of the horizon and the usual quantity salvaged at the end of the horizon, we introduce a new decision variable: a salvage opportunity at the beginning of the horizon, which might be used in the case of high initial inventory level. We develop the expression of the optimal policy for this extended model, for a general demand distribution. The structure of this optimal policy is particular and is characterized by two threshold levels. Some managerial insights are given via numerical examples.

Assume we are asked to predict a real-valued variable yt based on certain characteristics xt = (x1t , . . . , xdt), and on a database consisting of (x1i, . . . , xdi , yi) for i = 1, . . . , n. Analogical reasoning suggests to combine past observations of x and y with the current values of x to generate an assessment of y by similarity-weighted averaging. Specifically, the predicted value of y, yst , is the weighted average of all previously observed values yi, where the weight of yi, for every i = 1, . . . , n, is the similarity between the vector x1t, . . . , xdt, associated with yt , and the previously observed vector, x1i , . . . , xdi. The ''empirical similarity'' approach suggests estimation of the similarity function from past data. We discuss this approach as a statistical method of prediction, study its relationship to the statistical literature, and extend it to the estimation of probabilities and of density functions.Keywords:Density estimationEmpirical similarityKernelSpatial models

A spiral process model of technological innovation in a developing country: The case of Samsung

This article presents a spiral process model of indigenous technological innovation capabilities (ITICs) that shows how firms in a developing country initiate, imitate, improve and make innovative technologies. Any technological innovation passes through four stages: (1) technological innovation (TI), (2) transfer of technology (imitation), (3) adaptive technological innovation (improvement), and finally (4) indigenous technological innovation (local innovation). This paper reviews models and frameworks related to technological innovation capabilities (TICs) which are proposed in the context of developing countries. It then analyzes the Late-Starter, Samsung Electronics as a case in point to illustrate how Korean firms have built their ITICs. The model shows four developmental stages at Samsung Electronics as: (a) Entrance of foreign companies into the Korean market and their refusal to transfer their technologies to Samsung initiating its ITICs, (b) Samsung started TICs by means of reversing the engineering of imported foreign technologies and transfer of technology, (c) it improved TI by means of adaptive technological innovation strategy and finally (4) the capability to establish their own ITICs, to become one of the leading companies in the world which challenges firms from advanced countries in the global market. The paper also highlights the developmental changes in the semiconductor (DRAM technology) of Korea. Keeping past experiences in consideration, we conclude that this model provides useful implications for newly industrializing countries (NICs) following the same pattern of technological development.Author Keywords: Indigenous technology innovation capabilities; innovation in developing countries; spiral process model of technological innovation; Samsung Electronics KoreaKeyWords Plus: CATCHING-UP; PERSPECTIVE

Accrual Output-Based Budgeting (AOBB) in government has been disputed intensely among academics and practitioners. While normative, conceptual, or theory-based literature made promising claims about which benefits can be expected from reforming government accounting and budgeting, recent empirical research finds that at least some of these expectations have been massively overstated. The observed gap between promises and reality poses the question for the true benefits anew. Basing our analysis on practitioners' judgment, we suggest a general and prioritized landscape of perceived benefits (taxonomy). Our findings are derived from 42 interviews conducted in the context of two German federal states. Mapping our results to prior claims in the literature, we reveal that the practitioners interviewed do not see upsides in areas that former research deems to be important while other and previously not emphasized areas, such as mindset changes, seem to convince in practical life. The results of our analysis offer a profound basis for further exploration of the benefits and/or even cost/benefit evaluations. [ABSTRACT FROM AUTHOR]

A Universal Hubbub Wild of Stunning Sounds and Voices all Confused: The Genesis and Degeneration of Speech in Agamben's Infancy and History and Milton's Paradise Lost

In Infancy and History, Giorgio Agamben describes infancy as a leap across the divide which seperates phone from logos, or voice from discourse. Language is made possible by this very division, a fracture that man himself introduces as he emerges from infancy to become the speaking subject. Infancy thus represents the original dimension of humanity. A similar conception of infancy lies at the heart of John Milton’s Paradise Lost. But where Agamben theorizes on the origins of language, Milton describes the degeneration of voice and discourse. With Satan’s plunge into chaos, he fathoms the destruction of the very foundations of human language and culture, an utter breakdown of the logos into animal noise and affect

Aggregation of multiple prior opinions

Experts are asked to provide their advice in a situation of uncertainty. They adopt the decision maker's utility function, but each has a potentially different set of prior probabilities, and so does the decision maker. The decision maker and the experts maximize the minimal expected utility with respect to their sets of priors. We show that a natural Pareto condition is equivalent to the existence of a set ¿ of probability vectors over the experts, interpreted as possible allocations of weights to the experts, such that (i) the decision maker's set of priors is precisely all the weighted-averages of priors, where an expert's prior is taken from her set and the weight vector is taken from ¿; (ii) the decision maker's valuation of an act is the minimal weighted valuation, over all weight vectors in ¿, of the experts' valuations
