Dispositions, organisational commitment and satisfaction: A longitudinal study of MBA graduates

This study examines the relationships among dispositional sources of value preferences and personality attributes, organisational commitment and satisfaction using a longitudinal sample from MBA graduates in a US business school. After examining and comparing four types of models: (1) direct effects of dispositions on organisational commitment; (2) direct effects of dispositions on organisational satisfaction; (3) direct effects of dispositions on organisational satisfaction, which in turn explains organisational commitment; (4) mediation effects of organisational satisfaction on the relationship between dispositions and organisational commitment, the study shows that the models of direct effects of dispositions on organisational commitment, and the mediation effects of organisational satisfaction on the relationship between dispositions and organisational commitment are considered as reasonably good fit models. Ideal organisational values of freedom and reward-based value orientation have a direct relationship with instrumental commitment, and personality attribute of interpersonal relationship has a direct relationship with normative commitment. In addition, organisational satisfaction partially mediates the relationship between aggressiveness and instrumental commitment, along with the relationship between norm-favouring tendency and normative commitment. The results suggest that dispositional sources of individuals are powerful to have a relatively long-term impact on the relationships between individuals and organisation.
Nonlinear dynamic analysis of a cable under first and second order parametric excitations

Abstract It is well known that small periodic vibrations of a cable support through its axial direction produce large spectacular oscillations of the cable. This may occur when the frequency of the anchorage motion is close to the first natural frequency or twice the fundamental frequency of the cable. In this paper, a nonlinear dynamic study of a cable under first and second order parametric excitations is presented. The cable model takes into account sag as well as quadratic and cubic nonlinear couplings between in-plane and out-of-plane motions. As a numerical example, a single-d.o. f. planar model of a horizontal cable is used to study the effect of frequency and amplitude of excitation as well as the natural damping of the cable on its transient and steady state responses with a particular focus on the time needed to trigger first and second order parametric resonance.
Design optimization of a single phase inverter for photovoltaic applications

The objective for this paper is to present a novel inverter topology for photovoltaic (PV) applications, in particular for the AC-module. A modified version of the inverter proposed by Shimizu et al. solves a major problem within the original topology; regeneration of transformer leakage energy. Also presented is a decomposition of the currents and voltages inside the inverter. The decomposition is used to derive the stress and power losses, and hereby developing a tool for optimizing the inverter in terms of efficiency and ratings. Finally, the developed tool is used to design an inverter. The annual European efficiency is calculated to 81.8% for a 160 W inverter, which is regarded as high for an inverter for AC-module applications, as long the cost can be kept low.
Long-term radiation therapy-related risk of second primary malignancies in patients with lung cancer

Background With the improvement of cancer therapy, a second primary malignancy (SPM) occurs more commonly among cancer survivors. At present, it remains unclear whether the radiation therapy for the initial lung cancer will increase the risk of developing a SPM. This study aims to investigate the long-term risk of a SPM attributable to the radiation therapy in patients with the initial lung cancer. Methods Patients initially diagnosed with lung cancer between January 1975 and November 2011 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. SPM was defined as the occurrence of a second cancer at least five years after the diagnosis of the initial lung cancer. Age- and propensity score matching (PSM)-adjusted competing risk analyses were performed to compare the risk of SPM. Results Of 47,911 patients, 9,162 (19.1%) underwent radiotherapy for the initial lung cancer. The PSM-adjusted competing risk analyses showed that radiation therapy was associated with a lower overall risk of SPM (HR: 0.89, 95% CI: 0.84–0.94, P<0.001). Specifically, the risk of second primary melanoma (HR: 0.49, 95% CI: 0.29–0.81, P=0.006), second primary female breast cancer (HR: 0.65, 95% CI: 0.50–0.85, P=0.001), second primary prostate cancer (HR: 0.69, 95% CI: 0.58–0.84, P<0.001) and second primary thyroid cancer (HR: 0.23, 95% CI: 0.07–0.77, P=0.017) was found to decrease, while the risk for second primary esophageal cancer dramatically increased (HR: 1.76, 95% CI: 1.26–2.45, P<0.001). Conclusions In patients who received radiotherapy for the initial lung cancer, the risk decreased for second primary melanoma as well as for second primary cancers of female breast, prostate and thyroid gland but increased for second primary cancer of esophagus. On the whole, radiation therapy for initial lung cancer may not increase the overall risk of SPM.
State-of-Practice Review of Deep Soil Mixing Techniques in China

Deep soil mixing techniques have been widely adopted in China since the late 1970s and mainly used for ground improvement for structural support and earth-retaining structures for excavations. A comprehensive state-of-practice review on development, applications, soil-cement properties, mechanistic studies, design methods, and quality control of deep soil mixing techniques in China is presented. These research results will serve as a reference for advancing deep soil mixing techniques in the United States and other countries.
An efficient technique to lower the error due to the truncation of the scanning region in a bipolar facility

An efficient technique is developed in this article to extrapolate the near‐field data falling outside the measurement region in the bipolar scanning. It is based on the nonredundant sampling representations of the electromagnetic field and on the optimal sampling interpolation expansions. The singular value decomposition method is properly employed for estimating the external data. This allows one to reduce in a significant way the truncation error occurring in the near‐field–far‐field transformation with bipolar scanning. Numerical examples assessing the effectiveness of the technique are shown. © 2007 Wiley Periodicals, Inc.

Benefits management : delivering value from IS & IT investments

This book considers the topic of achieving value from IT from both theoretical and practical perspectives. It is based on extensive research which produced a comprehensive understanding and analysis of the issues involved and innovative new approaches that addressed those issues plus considerable practical application, in a wide range of organisations of the ideas, processes, tools and techniques that were developed. The book describes how IS/IT investments can be aligned accurately with organisational strategy and how the approach and ‘tool-kit’ can be used by business managers and IS/IT specialists to identify the benefits available from different types of investments in a variety of organisational contexts. It describes how business cases can be developed that enable the benefits to be planned for and then realised through techniques and processes that overcome the organisational barriers that often prevent successful implementation. It also considers the strengths and limitations of existing methods, and shows how the approach can be integrated with best practice in the areas of project and change programme management. The book concludes by explaining how the key concepts in the approach have been extended and adapted to improve strategy development and decision making as well as an organisation’s ability to implement its strategy successfully.
Mechanics of sediment movement

The purpose in writing these notes has been to present a discussion of a few topics central to a physical understanding of the mechanics of sediment movement. Discussion has been confined to unidirectional flows (excluding waves) of relatively small scale (excluding Coriolis effects). A large number of topics have been not considered at all or only in passing, including one of the most important problems in sediment mechanics: theories for the prediction of bed-load and suspended-load discharge. It seemed more important to try to develop some physical insight about the elementary processes of sediment movement than to attempt to elaborate any comprehensive quantitative theories of sediment movement.
A small size dual-mode patch filter

A small size dual-mode square patch resonator with slots etched in symmetrical shape is proposed. The filter response is obtained by exciting the degenerate modes and the first higher order mode of the proposed resonator through asymmetrical feeding. Area saving more than 80% with respect to the conventional degenerate dual-mode square patch filter and more than 20% with respect to the non-degenerate dual-mode patch filter can be achieved. Beside its compact size, the fractional bandwidth of the proposed structure can be reduced to half of the non-degenerate dual-mode filter; hence, more design flexibility. A bandpass filter is designed at 1.74 GHz with 6.9% fractional bandwidth on FR4 material with 4.2 dielectric constant and 0.78 mm thickness. Simulations are performed using full wave IE3D simulator. Simulations agree well with the experimental results.
Performance-Based Planning

This article examines the application of performance-based planning at the local level in the United States, Australia, and New Zealand. A review of the literature finds that there have been few evaluations of performance-based planning, despite its being used by many governments. The authors provide a comparative review of the experiences of various jurisdictions in implementing this form of zoning and present observations on its relative strengths and weaknesses. Findings suggest that many of the jurisdictions that adopted performance-based planning subsequently abandoned it because of the heavy administrative burden required, and where performance methods survived, they were typically hybridized with traditional zoning. If performance-based approaches continue to be used, there is a need to better understand the administrative and implementation implications of this type of land use regulation.
The Impact of Distant Hurricanes on Perception of Flood Risk in Local Housing Markets

This study investigates whether home buyers’ perception of flood risk can be affected by the occurrence of a large-scale but distant hurricane without direct impact. Using a dataset of residential transactions in Miami-Dade County, FL between 2005 and 2014, we find that the impact of a property’s flood risk exposure on its value varies over time, with a price penalty of 4% in hurricane striking period. By contrast, within a quiet hurricane period, properties within high flood hazard zones demand a price premium ranging roughly from 4% to 6%, which may represent the price impact of water-related amenities. The premium declined significantly upon Hurricane Sandy. Several possible explanations are provided and tested to explain the main findings. Our findings indicate that the occurrence of a disastrous hurricane which impacted faraway regions also raised local home buyers’ perception of flood risk, but for a short period of time (one quarter).
PROPOSED PREDICTIVE EQUATION FOR DIAGONAL COMPRESSIVE CAPACITY OF REINFORCED CONCRETE BEAMS

The current standard specifications of JSCE fo r the diagonal compressive capacity of RC beams only consider the effect of the compressive strength of conc rete and are not applicable to high strength concrete. This research aims to investigate the effect of vari ous parameters on the diagonal compressive capacity and propose a predictive equation. Twenty five I-beams were tested by three-point bending. The verification of the effects of concrete strength, stirrup ratio and spacing, shear span to effective depth ratio, flange width to web width ratio and effective depth was performed. The diagonal compressive capacity had a linear relationship to stirrup spacing regardless of its diameter. The effect of spacing became more significant with higher concrete strength. Thus, the effect of concrete strength and stirrup spacing was interrelated. On the other hand, there were slight effects of the other parameters on the diagonal compressive capacity. Finally, a simple empirical equation for predicting the diagonal compressive capacity of RC beams was proposed. The proposed equation had an adequate simplicity and can provide an accurate estimation of the diagonal compressive capacity than the existing equations.
Benefits of Coordinating Plug-In Electric Vehicles in Electric Power Systems: Through Market Prices and Use-of-System Network Charges

Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world. To this end, electrifying personal vehicles is believed to contribute to an affordable and reliable energy model that provides tolerable environmental impact. Representing an inherently flexible electricity demand, plug-in electric vehicles (PEVs) promise to facilitate the integration of variable renewable energy sources. Yet, how should the PEVs' system usage be ideally coordinated for providing benefits to electric power systems in the presence of resource scarcity? The thesis develops a model of an aggregation agent as the interface to the wholesale electricity generators, which is envisaged to be in charge of procuring energy in electricity markets, exposed to uncertainty in prices, fleet availability and demand requirements. This aggregator could coordinate the PEV charging either with direct load control (DLC), i.e., sending power set points to the individual vehicles, or with indirect load control (ILC), i.e., by sending retail price signals. Contributing to the technical literature this thesis has on the one hand proposed a two-stage stochastic linear program for the PEV aggregator's day-ahead and balancing decisions with DLC over a large fleet of PEVs, while accounting for conditional value at risk in the objective function. On the other hand, it has put forward a formulation of ILC coordination as a bi-level optimization problem given by mathematical programming with equilibrium constraints, in which 1) the upper level decisions on retail tariffs and optimal bidding in electricity markets are subject to 2) the lower level client-side optimization of PEV charging schedules. These decisions may respect a potential discomfort that could arise when PEV users have to deviate from their preferred charging schedule. Set in an existing, real medium voltage distribution network with urban characteristics and spatial PEV mobility, network UoS tariffs for capacity have been applied to both DLC and ILC scheduling by a PEV aggregator.

The Uncertain Consequences of Nuclear Weapons Use

Abstract : The considerable body of knowledge on the consequences of nuclear weapons use accumulated through an extensive, sustained, and costly national investment in both testing and analysis over two-thirds of a century underlies all operational and policy decisions related to US nuclear planning. We find that even when consideration is restricted to the physical consequences of nuclear weapons use, where our knowledge on effects of primary importance to military planners is substantial, there remain very large uncertainties. These uncertainties exist because important phenomena were uncovered late in the nuclear test program, have been inadequately studied, are inherently difficult to model, or are the result of new weapon developments. Nonphysical consequences, such as social, psychological, political, and full economic effects, are even more difficult to quantify and have never been adequately analyzed. As a result, the physical consequences of a nuclear conflict tend to have been underestimated, and a full-spectrum all-effects assessment is not within anyone's grasp now or in the foreseeable future. The continuing brain drain of nuclear scientists and the general failure to recognize the post-Cold War importance of accurate and comprehensive nuclear consequence assessments do not bode well for improving this situation.
Sustainable Reclaimed Water Management by Subsurface Drip Irrigation System: a study case for forage production

In the Canary Islands the price fluctuation of groundwater (0.3 to 0.7 €/m3), which is a private resource, often limits the recovery of the agricultural investments. Availability of alternative resources (reclaimed water: RW, desalinized seawater: DW and desalinized reclaimed water: DRW) at a foreseeable price will allow people to design the optimal infrastructures adapted to their needs The pumping cost is included in the “public” water price of DW (0.6 €/m3), RW (0.2 €/m3) and DRW (0.42 €/m3), but only if it is under 300 m of altitude. As a subsurface irrigation system (SDI), uses the soil as a natural advanced (but not high cost) water treatment, the in situ reuse of RW produced by lower tech wastewater plants would provide a valuable resource for the small villages. A successful study case is presented here. A 2-year SDI experiment was performed using RW, cultivating alfalfa ( Medicago sativa ) and Sudan grass hybrid ( Sorghum bicolor ssp sudanense ). Although a saline (EC: 2.24 dS/m) and sodic (SAR: 6.9) water was used, irrigation with SDI led to high forage yields (between 8.4 and 11.9 kg of fresh matter/m2 obtained by 8 harvests per year). However, sand filter and drip lines have to be cleaned weakly and every 6 months respectively. As a conclusion of this study, adequate plant germination and yields, and feasibility of SDI using a secondary effluent was demonstrated. Besides, water cost represents only 24 to 17 % from the gross income.
Accurate measurement of original current pulses because of positive corona in the coaxial cylindrical arrangement

Current pulse because of positive corona discharge is a main source of radio interference (RI). An accurate measurement of the original corona pulse is necessary to study corona-generated RI. However, the corona pulse is likely to be distorted by either LC oscillation or reflection. In this study, an experiment system with single corona source is built which can provide a nearly free-reflection path for the current pulses, and measurements are carried out in the system. The magnitude of the measured waveform is close to one half of the original pulse, which proves the accuracy of the measurement method. In order to obtain the original current pulse, a comprehensive model for the current pulses’ path, taking the stray capacitance and stray inductance into consideration, is established. Based on the model, an inversion method to derive the original pulse is proposed. In combination with the obtained original pulse, the model gives the calculated results for other experimental conditions. The calculated results agree well with the measured results, which provide solid validation for the accuracy of the measurement. Another advantage of the proposed measurement method is that the long cables enable the accurate measurements to be achieved under any terminal conditions.
