Risk Management Affecting IS/IT Project Success through Communicative Action

Project risk management is defined in the literature as being instrumental action based on rational problem solving. Research indicates limited positive effects of an exclusive focus of instrumental action on project success. This article proposes to extend this instrumental view through communicative action. This theoretical broadening was explored by interviewing project stakeholders about project success and risk management application. Analysis demonstrates stakeholders deliberately use risk management to convey messages to others, with the aim of influencing their behavior, synchronizing their perception, and making them aware of the context and their responsibilities. Stakeholders perceive these effects as contributing to project success.
Development of a new control strategy for a semi-active differential for a high-performance vehicle

Although VDC systems usually operate on the engine torque and on brake pressures [Van Zanten, A.T. , Erhardt, R. and Pfaff, G. , 1995, VDC, The Vehicle Dynamics Control System of Bosch. SAE Technical Paper Series, no. 950759, Esmailzadeh, E. , Goodarzi, A. and Vossoughi, G.R. , 2003, Optimal yaw moment control law for improved vehicle handling. Mechatronics 13. ] new automotive applications try to use semi-active or active differentials in order to optimize the torque distribution on the wheels for traction maximization, driving comfort, stability, and safety of the vehicle. The system presented in the article comes from the cooperation of Ferrari S.p.A. and Politecnico di Milano in the development of a new semi-active differential. In the article, a description of the vehicle dynamic control strategy, its development, and experimental results are presented.
Error analysis and Hertz vector approach for an electromagnetic interaction between a line current and a conducting plate

In the present paper we first introduce the Hertz vector potential and examine how the specific case of electromagnetic field diffusion problems can be formulated in terms of this potential. Its connection to other commonly used potentials is presented and a basic approach in the form of a suitable set of equations is introduced. The suggested method is then successfully applied to solve the case of an electromagnetic interaction between a straight conductor carrying sinusoidal current and a finite thickness fixed plate. Due to the oscillatory aspect of the integral solution obtained, an appropriate numerical treatment is investigated and various curves are shown to illustrate the convergence behaviour.

An Axial Compressor End-Wall Boundary Layer Theory

The essential ingredient missing in existing prediction methods for the performance of multistage axial compressors is that which would account for the effect of end-wall boundary layers. It is, in fact, believed that end-wall boundary layers play a major role in compressor performance and the absence of an adequate theory represents a handicap to turbomachinery designers that might be likened to the handicap that designers of wings, for example, would face if Prandtl had not introduced the idea of a boundary layer. In this paper a new theory is developed which retains all elements of classical boundary layer theory; for example, we discuss variables such as momentum thickness and wall shear stress. However, the present theory introduces new concepts such as axial and tangential defect force thickness, a rotor exit-stator inlet “jump condition” and the importance of these concepts is demonstrated. Inherent in the derivation is an identification of the role of secondary flow and tip clearance flow. A proper means of matching the boundary layer calculations to conventional main stream calculations is suggested. Independent of empirical parametization it appears that the theory is capable of correctly modeling boundary layer blockage, losses, and end-wall stall. Near stall, the main stream-boundary layer interaction is very strong.

What effort does it take to deploy an open source ERP

ERP systems are rapidly becoming a de facto standard in business activity. While large and medium-sized companies have the luxury to afford proprietary ERP solutions, small companies are struggling with resource poverty which forces them to consider other solutions. One solution available could be open source ERP products especially since these are without a license cost. However, there is little knowledge available on open source ERP adoption in small companies. That is why the first step is to spread light on open source ERP deployment in terms of knowledge and time. The purpose is accomplished by using the research framework based on Technology Acceptance Model 2 (TAM2), usability testing and user training and education factors. The factors of Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) are used to determine the ease of deployment process, and the usefulness of the open source ERP deployed in relation to the made effort. The research method implied a pre-study and an experiment. The pre-study’s purpose was to obtain an insight on open source ERP deployment process before any experiments are made. An initial experiment was setup with three IT-related students. The empirical study was then complemented with additional three students with non-IT background in order to build evidence for stronger conclusions. The findings suggest that user with advanced computer skills perceive open source ERP deployment process as easy, and the open source ERP being useful to the business activity.
Deployment and impact of support staff in schools : the impact of support staff in schools : results from strand 2, wave 2

This study was designed to obtain up to date and reliable data on the deployment and characteristics of support staff and the impact of support staff on pupil outcomes and teacher workloads. The study covered schools in England and Wales. It involved large scale surveys (Strand 1), followed by a multi-method and multi informant approach (Strand 2). It provided detailed baseline data by which to assess change and progress over time. It sought to understand the processes in schools which lead to the effective use of support staff. The DISS project was funded by the Department for Children, Schools and Families (DCSF) and Welsh Assembly Government (WAG).
Assessment of Life Cycle Energy Saving and Carbon Reduction of Using Reclaimed Asphalt Concrete

This study uses the Pavement Life-cycle Assessment Tool for Environmental and Economic Effects (PaLATE) to study the benefits of energy savings and carbon emission reduction derived from using Reclaimed Asphalt Pavement (RAP). According to the findings, producing RAP mixture with 30% of reclaimed asphalt materials results in 16% of energy saving and 20% of carbon emission reduction while compared to that of producing the same amount of virgin hot mix asphalt mixture. The mitigation of energy consumption and carbon emission is mainly due to the saving on virgin asphalt binder. However, it is found from a life cycle approach, only if RAP pavement gives a service life at least 80% of that of virgin materials, using RAP becomes a feasible way to make the pavement greener.
The perceptions of clergy on domestic violence: a perspective from the Kwa-Zulu Natal Midlands

The issue of domestic violence is not a private matter. It inadvertently affects all members of society, including service professionals who assist victims and perpetrators. Among those inflicting violence are members of the Christian community, despite their orthopraxy that condemns violence. Some believe that clergy, the “shepherds of the flock”, play a pivotal role in fostering attitudes that either condone or condemn violence in society. Subjugating women restricts them from reaching their full potential. An understanding of the ways in which clergy manage institutionalised systems of dominance may lead to a cultural shift that does not tolerate dominance by one over another. This qualitative study uses a Feminist Liberation Theology framework1 to explore the perceptions of clergy from the Midlands region of KwaZulu-Natal on the issue of dealing with domestic violence in the Christian community. 1 Due to the fact that this qualitative study used a Feminist Liberation Theology framework – although we admit that other theoretical perspectives could make valuable contributions to a similar study – it falls outside the specific focus of this particular study. Future studies can benefit from extending the theoretical scope to include, for instance, liberation theory. The Feminist Liberation Theology theoretical framework serves, among others, the purpose of consciousness raising, a position also taken by Liberation Theology (Schüssler Fiorenza 1975; Ruether 1993; Ackermann 1996; Dreyer 2011; Morkel (2012; 2015).

The Influence of Fiscal Policy on Foreign Direct Investment Inflow: A Case Study of Ireland

The level of influence from fiscal policy on foreign direct investment inflow (FDI) is controversial. This study investigates the relationship between foreign direct investments and corporate tax rates relative to other determinants within the European Union compared to Ireland. In this study, a panel regression analysis was employed to evaluate data from the United Nations Conference on Trade and Development (UNCTAD), World Bank and Organization for Economic Co-operation and Development (OECD) from 1990-2017. The result shows that there is a positive correlation between corporate tax rate, labor force, and foreign direct investment inflow in Ireland. Also, the corporate tax rate, inflation rate and Labor force rate have a significant impact on the FDI inflow in the economy growth of the Ireland. The understanding of the behavior of these factors can provide useful information to the Ireland government and policy makers as they seek to improve foreign direct investment inflow through building more infrastructure, increased market share, education quality and reformation in tax policy to encourage domestic investment and attract new investors to the Nation. The study recommends that firms seek financial gain through corporate tax rates as a leading determinant and aim to identify how corporate tax rates contrast in FDI levels between countries within the EU should acknowledge that other factors that can create a healthy business environment for sustainable growth for both in the investing MNEs and host nations.
MONITORING BEHAVIOR OF GROUTED ANCHORS USING VIBRATING-WIRE GAUGES

Long-term monitoring of the behavior of ground anchors constitutes an important aspect of the stability of structures reinforced by such structural members. The present paper describes full-scale tests performed on three instrumented grouted anchors in the laboratory and one other instrumented anchor in the field. Due to the long-term reliability, stability, and accuracy, two types of surface-mounted vibrating wire gauges were used to instrument the anchors. A series of vibrating-wire gauges were microwelded on the anchors at certain intervals along their lengths. The performance of these gauges, the load transfer mechanism, the debonding process, creep behavior, and long-term performance of the anchors under loading, unloading, and sustained loading, were investigated in the laboratory. A practical application and test results of an instrumented anchor at Jeffrey Mine in Asbestos, Canada, are described. The results obtained show that this instrumentation technique of grouted anchors is efficient for long.
Carbon dioxide enrichment and irrigation effects on wheat evapotranspiration and water use efficiency

Evapotranspiration (ET) and water use efficiency were evaluated for two spring wheat crops, grown in a drip-irrigated field under ambient (about 370 mmol mol–1) and enriched (550 mmol mol–1) carbon dioxide (CO2) concentrations during the 1992-1993, and 1993-1994, Free-Air CO2 Enrichment (FACE) experiments in central Arizona. CO2-enriched (FACE) and ambient CO2 (CONTROL) treatments were replicated in four circular plots, 25 m in diameter, and well-watered (WET) and water-stressed (DRY) irrigation treatments were imposed on one-half of each plot. Wheat ET, measured over discrete time periods of several days by a soil water balance, was significantly higher for WET than DRY irrigation treatments after the first week in March in both years. Differences in ET between CO2 treatments during the season were generally small, although there was a consistent trend towards decreased ET for the FACE over CONTROL under the well-watered irrigation regime.
Effect of reduced spacing on relationship of physiological, morphological and productive traits of corn yield

Increasing corn grain production without devastating new forest areas is a viable alternative to controlling deforestation. However, increasing plant density in the area may alter plant morphophysiological and productive traits. The objective of this study was to characterize relationships between physiological, morphological and yield traits of corn plants, as well as the cause, effect and relationship of the traits on grain yield. The experiment was carried out in randomized complete block design with four replications. The corn hybrids (2B655PW, AG7088PRO3 and P4285YHR) were grown with row spacing of 40 cm, 60 cm, 80 cm, 95 cm. The evaluated traits physiological were: net photosynthesis (PN), stomatal conductance (Gs), intercellular concentration of CO2 (Ci), leaf transpiration (E), water use efficiency (WUE) and carboxylation efficiency (CE). The morphological were: plant height (PH) and ear insertion height (EIH), stem diameter (SD), and leaf area (LA) and the productive traits were the total number of ear per hectare (NE), number of grains per ear (NGE), grain mass per ear (GME), 100 grain weight (100GW) and grain yield (GY). The characteristics of maize hybrids cultivated in environment with reduced spacing (40cm, 60cm, 80cm, 95cm) of the 2016/2017 crop were investigated through the multicollinearity path analysis. The physiological, morphological and productive traits are considered sources of variation of cause and effect of corn yield in reduced spaced. This traits are essential for observations in maize breeding programs to obtain high yielding varieties in reduced spacing. In conclusion, the physiological (PN, CE, WUE, Ci, Gs), morphological (EIH, SD, LA) and productive (NE, GME) traits provide gains in maize grain yield via indirect selection when the crop is subjected to 40 cm row spacing.
Ferroelectric Conversion of Heat to Electrical EnergyA Demonstration

The conversion of heat to electricity by means of the pyroelectric effect is demonstrated here. The basic thermal-electrical cycle is described. The production of 100 mj of electrical energy per cubic centimeter of ferroelectric material (PZST) per thermal cycle (with a temperature span of 20°C) has been observed. This observation is discussed in terms of using regeneration to approach Carnot efficiency. The staging of ferroelectrics to increase the temperature range (and hence efficiency) is also explained.
Flow Requirements of Spawning Atlantic Salmon in an Upland Stream: Implications for Water‐Resource Management

The spawning sites selected by female Atlantic salmon (Salmo salar) were surveyed over three consecutive years in the Girnock Burn, Aberdeenshire, Scotland. Discharge was calculated for each spawning site to assess within‐catchment variation in spawning discharge selection. In total, 428 incidents of female spawning activity were logged at 48 sites. Fish selected relatively high flows in which to spawn, with the lowest utilised discharge being equivalent to the burn's 50 percentile flow.
Empirical relationships between natural vibration period and height of buildings in Singapore

Singapore is a classic case of a modern metropolis with low hazard but high exposure to the seismicity in Sumatra. Because of land shortage, more than 80% of the population lives in high‐rise residential buildings. As part of the efforts to assess the seismic performance of buildings in Singapore subjected to long‐distance Sumatran earthquakes, relationships between the natural vibration period and height of high‐rise public residential buildings in Singapore are derived empirically by conducting ambient vibration tests on 116 buildings. The measured buildings have a height ranging from 4 to 30 stories. The aspect ratio of buildings in plan is found to be insignificant in affecting the natural vibration period of the first mode of the buildings. The period‐height relationships are derived using regression analysis considering the site properties of a building. It is concluded that the vibration periods estimated from the proposed period‐height relationship for buildings located at soft‐soil site are about 40% longer than the vibration periods estimated for buildings located at firm‐soil site. Measurements are also conducted to study the influence of buildings on the measured frequency of the surrounding soil. For this purpose, two buildings with 25 and 30 stories located at firm‐soil site and soft‐soil site, respectively, are selected. It is found that the distance of building influence on the measured frequency of the surrounding soil may reach up to one building height for a firm‐soil site and two building heights for a soft‐soil site. Additional data of natural vibration periods of 19 instrumented residential buildings, which have height ranging from 9 to 30 stories, were obtained from the building response recorded during the September 30, 2009 Sumatran earthquake event. The natural vibration periods of these buildings are compared with those estimated using the proposed period‐height relationships, and the absolute differences are found to be less than 12%.

Integrated Passenger Information System for Multimodal Trip Planning

The integration of wireless and web-based communication technologies in advanced public transport information systems has led to the provision of passenger information services directly to the users. Most of the existing systems provide alternative travel plans either for urban or for single-mode interurban trips. The objective of this paper is to present an online passenger information system for delivering personalized trip-planning services for interurban multimodal trips, including plans for any constituent urban transfer. The proposed system accommodates the provision of critical real-time travel information (e.g., delay or cancelation of flights) to the user throughout the entire life cycle of an interurban trip. The major features of the system are the following: (a) determination of optimum itineraries in a multimodal public transportation network, (b) online updates of the departure times throughout the entire life cycle of the trip, and (c) dissemination of travel information through several communication channels. The proposed system supports two major trip-planning decisions: (a) itinerary planning for an urban trip through the local public transport network, and (b) combined urban and interurban trip planning. The focus of the paper is on the presentation of the design and implementation of the proposed system and its application for supporting trip-planning decisions in Greece. An evaluation of the system has indicated that it is user-friendly, is cost-effective, and meets travelers’ requirements.
Evaluation of safety of helmets using a featureless Hybrid III headform

This paper proposes a new procedure for designing helmets for head impact protection to road users such as two-wheeler riders and pedestrians. The new procedure suggests that a helmet be mounted on a featureless Hybrid III headform that is used for assessing upper interior head impact safety specified in the vehicle safety standard FMVSS 201 in the USA. To ascertain a helmet's effectiveness as a countermeasure for minimising the risk of severe head injury, an impact velocity of 6 m/s (13.5 mph) was used for the helmet-headform system striking a rigid target. The resultant head impact response is measured by Head Injury Criterion (HIC). The threshold HIC(d) limit of 1000 is applied for adjudging the efficacy of helmets. The proposed procedure is demonstrated with the help of a validated LS-DYNA model of a featureless Hybrid III headform and a helmet. The helmet model consists of an outer General Electric (GE) plastic-based shell to the inner surface of which is bonded a protective energy-absorbing foam padding of a given thickness. Based on simulation results of impact on a rigid surface, it appears that foam padding of suitable strength and a minimum thickness of 35–40 mm along with a shell thickness of 3–4 mm is necessary for obtaining an acceptable value of HIC(d), and therefore, an acceptable helmet safety design.
Stabilization of Silty Sand with Nontraditional Additives

A laboratory experiment was conducted to evaluate the stabilization of a silty- sand (SM) material with nontraditional chemical or liquid stabilizers. SM soil specimens were mixed with various stabilization products and compacted using a gyratory compaction machine to approximate ASTM D1557 moisture—density compaction. Each specimen was subjected to wet and dry testing following the designated cure period. Twelve nontraditional stabilizers were evaluated in this experiment, including acids, enzymes, lignosulfonates, petroleum emulsions, polymers, and tree resins. Additional specimens were stabilized with an asphalt emulsion, cement, and lime to provide a comparison with traditional stabilizers under the same mixing, compaction, and curing conditions. The analysis of the test data consisted of determining the average strength, in terms of sustained load, of three replicate specimens of each mixture. The average strength of the three replicates of each additive was compared with the average strength results of the remaining nontraditional additives, the traditional stabilization results, and a series of control specimens that were not stabilized. The results of the experiment indicate increased strength of some nontraditionally stabilized specimens compared with that of both the control series and the traditional stabilization alternatives. Other nontraditional stabilizers did not demonstrate significantly increased strength compared with the control series for the conditions of the experiment. Many of the stabilized specimens were highly moisture susceptible, indicating the potential for poor performance when they are exposed to adverse environmental conditions, whereas a few specimens demonstrated excellent performance when exposed to moisture. Specific product categories are recommended for stabilizing SM soils.
