This paper presents Maritrans’ groundbreaking experience in rebuilding very large single hull barges into OPA- 90 compliant double hull barges. Details of the process are described along with interesting case studies involving aspects of analysis and construction. The process by which the American Bureau of Shipping certified this barge to be a “Grade 1” under the ABS SafeHull Condition Assessment Program is described in detail. There is a brief discussion of extending this rebuild process to the double hulling of tankers.

The Asphalt Pavement Layer Condition Assessment Program (APLCAP) is developed in this research to help highway agencies assess layer conditions of asphalt pavements. APLCAP implements a new integrated procedure for condition assessment from falling-weight deflectometer (FWD) deflections. The main components of this procedure include screening of FWD raw deflections, predictions of condition indicators from FWD measurements, structural adjustments for the predicted condition indicators, and layer condition evaluation based on the adjusted condition indicators. This procedure was developed on the basis of dynamic nonlinear finite element analysis and calibrated using field measurements. The three case studies presented show that the APLCAP algorithms can predict the asphalt concrete modulus, pavement critical strains, and strengths of the base and subgrade quite well, but not the compressive strain in the aggregate base layer. Although the APLCAP procedure includes the complicated dynamic effect of FWD loading and nonlinear behavior of unbound materials, the time to obtain results from this procedure is insignificant and therefore suitable for real-time evaluation of pavement conditions.

An outline of formulation based on a layerwise beam theory for unbalance response and stability analysis of a multi mass, multi bearing composite rotor mounted on fluid film bearings is presented. Disc gyroscopics and rotary inertia effects are accounted for. Material damping is also taken into account. The layerwise theory is compared with conventionally used equivalent modulus beam theory. Some interesting case studies are presented. The effect of various parameters on dynamic behavior and stability of a composite rotor is presented.

The relentless pressures of competition stemming from globalization, technological changes, etc., today are increasingly buffeting organizations. One of the pathways for companies to weather these storms is through unleashing the entrepreneurial spirit latent in its employees enabling these employees to carve out new paths, initiate new ventures, defy the status quo in their organizations, and break fresh ground. There is an increasing body of knowledge relating to unleashing entrepreneurial energies in large organizations referred to as corporate entrepreneurship or intrapreneurship. Intrapreneurship is a major driver for organizational renewal or reinvention. This article seeks to understand the intrapreneurial mindset as opposed to the employee mindset. It is inextricably connected with leadership since it involves mobilizing teams of people towards a cause much greater than the individuals involved, often in the face of significant resistance from status quo preserving forces within and outside the organization. Intrapreneurship at any level (individual, group or organization) fundamentally involves taking ownership, i.e., operating with an entrepreneurial mindset. In the corporate context, since the person leading the reinvention is not an autonomous entrepreneur, he/she is more appropriately referred to as an intrapreneur. It is very unlikely that reinvention at any level can occur without this basic transformation of perspective from employee to psychological owner or intrapreneur. Intrapreneuring is not a path that is chosen by the vast majority of people in any profession since this path involves a lot more of the person than would be the case for a person operating with an ‘employee mindset.’ However, the reason it is important is that it is challenging, fulfilling, personally and professionally rewarding, and is urgently required by corporations—both big and small—the world over to thrive meaningfully in todays uncertain times. While the context in which this manifestation of entrepreneurial behaviour is enacted may vary (government, public sector, private sector, NGO, etc.), the fundamental fibre of the person who chooses this path is essentially similar. This article presents three interesting case studies from Tata Steel, a company that has sought to create an entrepreneurial climate in the organization over the last several years. Two of these relate to crashing project time and cost lines to create international records in the face of international technical collaborators affirming that this would not be possible in India. The third intrapreneurial episode relates to turning around a run-down manufacturing facility in the company to produce spectacular results. In the process, the authors have: drawn generic lessons from each of these case studies presented the results of interviews with 30 practising managers on the facilitators and inhibitors for creating an intrapreneurial climate in large organizations highlighted the perspectives of a few senior managers from the Indian IT industry on this very important source of innovation in large organizations tied together the three intrapreneurial episodes presented in this paper by attempting to understand the commonalities among the intrapreneurs. This article would be beneficial to Indian companies seeking to create an entrepreneurial climate and to professionals in these companies to motivate them to look at their work lives differently and to enable them to redefine their roles in their organizations.

The title of this edited volume leads one to expect a timely contribution to the literature on language socialization, which has become increasingly concerned with bilingual and multilingual settings over the past decade or so. Some readers with general interests in bilingual and multilingual situations, or with special interests in education in such settings, may find this collection worthwhile. Those with a particular interest in language socialization, however, will be disappointed – and perhaps irritated to have been misled by the title. The volume's 16 chapters present a broad variety of interesting case studies, but very few among them can accurately be characterized as language socialization studies.
