Full textAbstract:
This paper investigates the effectiveness of using a corporate enterprise resource planning (ERP) system as a multi-dimensional project control system (MPCS) to monitor and control the work performed on projects, meet the needs and expectations of the project managers and support the requirements of other key stakeholders. A qualitative approach i.e. case study interviews and literature review accompanied by a quantitative computer system validation test approach was deployed. The results from this study suggest that the corporate ERP system is effective at monitoring and controlling the project stakeholder success criteria within a fully integrated environment. The system does however need to be setup and configured for the purpose of MPCS. This study contributes to the field by providing empirical evidence that corporate ERP systems are likely one of the only systems truly capable of solving the age old problem of how to expand the traditional singular dimensional approaches commonly used in project control, thus multiple control dimensions are integrated with each other and other business systems to form a multi-dimensional project control system.

Full textAbstract:
This paper presents a resources-based theory perspective of managing a SAP project team in order to realize a sustainable competitive advantage. Resource-based theory suggests that resources which are durable, not easily replicable, and imperfectly mobile can be effectively leveraged by the firm in order to achieve a sustainable competitive advantage over its competitors. The analysis which is presented in this paper suggests that the effective implementation of the SAP system by a firm requires not only an acquisition of a high level of technical expertise, but a change in organizational culture from one which rewards individual brilliance to one which encourages project teams. This will create an environment in which the success of any individual in his job is critically dependent on the skills possessed by the other team members. This will render the human component of the SAP resource imperfectly mobile and increase the capability of the firm to leverage this resource in order to achieve a sustainable competitive advantage.

Full textAbstract:
This play attempts to reconstruct the social reality of key players at Metalica during the first couple of years of SAP implementation. Rather than adopting one perspective about the SAP project, we provide the views of different participants using their own words, arguments and ideas as much as possible. The play is constructed from summaries of systematic interviews which were changed only to suit scholarly objectives and a dramatic presentation. At the request of the company involved, the names and locations in this case have been disguised. Act 1 describes the company's vision concerning the implementation of an enterprise resource planning (ERP) system, a crisis which emerged during the initial phase of implementation and the actions taken to remedy the shortfalls. Act 2 describes the project management, the dynamics between the implementation team members and the organizational implications of an ERP system implementation. The actual performance of the play and a subsequent discussion among the participants enable students to re-create and experience the thrills, frustrations, dilemmas and concerns originally expressed by the people who inspired this account of SAP implementation. Using theatre in an academic environment opens new avenues for critical observation, integrative sense making and experiential learning.

Full textAbstract:
The goal of this research project is to develop a simulation model specifically for the Management Accounting Information Systems course an SAP enabled course for junior Accounting majors at Saint Joseph's University. The purpose of this simulation is to present students with a set of business scenarios, and have the students make a knowledgeable decision using SAP Business Warehouse software. The scenarios will act as a simplified replication of the business environment; thus, they will provide the students with an integrated learning experience. They will make business decisions to ensure the profitability and cash flow of a corporation. While making these decisions, students participate in the application and analysis provided by PC4YOU, which is a simulated company within SAP for demonstration and education purposes. Eventually, the students will need to justify the existence of their strategic plans by evaluating benefits of the system using the reporting tools available within SAP. To provide a learning by doing experience, the scenarios will be used to demonstrate the reporting functionality within PC4YOU, the simulated company integrated into the SAP SEM system. Todays global economy is putting a premium on the ability of students to evaluate a broad range of decisions in collaboration with adaptive supply chains. A critical component of the evolving accounting curriculum lies in the ability to extend students beyond the numbers to evaluate the effective and efficient delivery of these supply chains.

Abstract Background and Purpose: Many researchers have investigated various Critical success factors (CSFs) and the different causes of ERP implementation project failures. Despite a detailed literature preview, we were unable to find an appropriate research with a comprehensive overview of the true causes behind CSFs, observed from a human factors perspective. The objective of this research was therefore to develop and evaluate the Primary human factors (PHFs) model and to confirm the significant impact of PHFs on traditional CSFs and on the project success. Design/Methodology/Approach: The comprehensive PHFs research model was developed and examined in empirical quantitative research with the use of available literature and the application of the Root cause analysis. A survey was conducted in various Slovenian organisations in different branches that had previously implemented the ERP system SAP. The model was verified on a sample of 21 experts from 18 organisations. Results: The results show that the PHFs have a significant positive impact on the ERP implementation project success, but only the Competence and Team composition factors are significant linear predictors in an adapted regression model and contribute significantly in predicting project success. These results therefore confirm both proposed hypotheses and the adapted regression model. Conclusion: This study improves the understanding of PHFs and confirms that they have a significant impact on traditional CSFs and the ERP implementation project success. The proposed PHFs model offers project managers and other stakeholders an effective risk assessment of CSFs and is leading the way to human oriented model of ERP implementations.

PT XYZ is one of the mining companies in Indonesia that has many subsidiaries. From user interviews, there’s a problem in carrying out daily transactions in the procurement process. There is no integration between departments when using existing applications, lots of inappropriate data, and some documents with missing files. Thus causing data not on time and working time. The analysis was carried out using a conceptual model to see the problems and needs in PT XYZ. ERP system needs to be implemented, coordinating the company’s business processes and reset the company’s infrastructure and standardization. The ERP system in the material management module will be implemented using the ASAP method because this method is tailored to the company. The ASAP method can describe implementation activities to support project management and data migration faster than other implementation methods.

Full textAbstract:
Kisspeptin, a neuropeptide encoded by the KISS1/Kiss1, and its cognate G protein-coupled receptor, GPR54 (kisspeptin receptor, Kiss-R), are critical for the control of reproduction in vertebrates. We have previously identified two kisspeptin genes (kiss1 and kiss2) in the zebrafish, of which kiss1 neurons are located in the habenula, which project to the median raphe. kiss2 neurons are located in the hypothalamic nucleus and send axonal projections to gonadotropin-releasing hormone neurons and regulate reproductive functions. However, the physiological significance of the Kiss1 expressed in the habenula remains unknown. Here we demonstrate the role of habenular Kiss1 in alarm substance (AS)-induced fear response in the zebrafish. We found that AS-evoked fear experience significantly reduces kiss1 and serotonin-related genes (plasmacytoma expressed transcript 1 and solute carrier family 6, member 4) in the zebrafish. Furthermore, Kiss1 administration suppressed the AS-evoked fear response. To further evaluate the role of Kiss1 in fear response, zebrafish Kiss1 peptide was conjugated to saporin (SAP) to selectively inactivate Kiss-R1-expressing neurons. The Kiss1-SAP injection significantly reduced Kiss1 immunoreactivity and c-fos mRNA in the habenula and the raphe compared with control. Furthermore, 3 d after Kiss1-SAP injection, the fish had a significantly reduced AS-evoked fear response. These findings provide an insight into the role of the habenular kisspeptin system in inhibiting fear.

Summary Objectives: The Styrian Hospital Organization with 21 hospitals including the Graz University Hospital, and the Heidelberg University Hospital implemented a new HIS based on SAP/R3™, ISH™, ISH*MED™ with the objective to have an integrated system to support patient administration and management, patient care, clinical documentation, research etc. Methods: Heidelberg University Hospital chose a step by step method for the introduction of the system, beginning with patient administration (ISH) and proceeding with clinical functions (ISH*MED). In Styria, the full functionality was implemented – as part of the selection process – in one peripheral hospital and in the Ear, Nose and Throat (ENT) Department of the Graz University Hospital, including special documents to support the processes in the highly specialized ENTunits. Results and Conclusions: The standard modules are performant, stable and basically well accepted. Particularly in Graz, it has been shown that the requirements of highly specialized departments for work flow management, documentation and integration of subsystems and data from different sources can be fulfilled by special documents and programs – although at the expense of additional workload particularly in the initial phases of such a project.

Building on our 2019 ISSOTL poster presentation, we (Michael: a tenured English Department faculty member; and Emily: an undergraduate English major) are developing a reflective essay about our in-progress SaP project designed to assess the effectiveness of recent university system mandated curricular changes to multiple sections of an introductory college-level writing course at our home institution, the University of North Georgia, USA. Even though we received the necessary institutional and federal government permissions to conduct this research, and even though the research participants signed the necessary informed consent document, as we continue our data collection we wonder how we might better listen and watch for what Bivens (2018) calls “microwithdrawals of consent.” Bivens describes this phenomenon as the “implied or partial halt of a person’s willingness to participate in one or more aspects of the research process and the researcher’s awareness of that withdrawal.” Bivens calls on researchers to stay attuned to the participant’s body language and vocal tone to notice when participants may want to withdraw consent but not explicitly say so. When undergraduate researchers conduct interviews with other undergraduates, they are well-positioned to perceive these microwithdrawals of consent. With Emily as the lead author for this proposed piece, we wonder: How can students working in partnership with faculty help faculty better understand how informed consent is an on-going and negotiated process that does not end when research participants sign a consent document? Pondering this question emphasizes the “messy, ‘work in progress’ nature of SaP” (Matthews, 2017, p. 4), which, we argue should hold a central place in our SaP publications.

Full textAbstract:
Purpose – The purpose of this paper is to investigate the factors of m-learning approaches which can be used for enterprise resource planning (ERP) system training and to propose a theoretical framework for m-learning of ERP systems. Design/methodology/approach – A literature review of several theories relating to success factors for mobile learning (m-learning) and electronic learning (e-learning) are analysed and a theoretical framework of success factors for m-learning of ERP systems is proposed. Two field studies are undertaken to identify the features of e-learning and m-learning systems which users enjoyed and which related to the factors identified in the theoretical framework. The technology acceptance model (TAM) was used to evaluate the acceptance, usefulness and perceived ease of use (PEOU) of the two systems evaluated in the field study, the openSAP e-learning application and the SAP Learn Now m-learning application. Findings – The results confirmed several of the theoretical elements identified in the framework and the m-learning system was rated positively for PEOU and perceived usefulness (PU). The findings confirmed other studies showing the importance of the quality of course content in e-learning and m-learning projects. Research limitations/implications – The empirical study was limited to a small number of participants in higher education. However, a deeper understanding of the factors influencing m-learning for ERP systems was obtained. Practical implications – The study provides a valuable practical contribution because the framework can be used in the improved design of an ERP m-learning approach, which in turn can lead to an improvement in ERP training and education programmes and ultimately ERP project success. Originality/value – Several studies propose the use of m-learning systems. However, research related to the factors impacting on m-learning projects for ERP system training is limited. The paper presents original work and the results provide a valuable contribution to several theories of m-learning.

Category: Ankle Arthritis Introduction/Purpose: Total ankle replacement (TAR) is performed for post-traumatic arthritis, inflammatory arthropathy, osteoarthritis and other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1997. In this study, using data from the SAP, we look at trends in the use and outcomes of TAR in Scotland. Methods: We identified 499 patients from the SAP who underwent TAR between 1997 and 2015 with imaging available on the National Picture Archiving and Communication System (PACS). We identified, and looked at trends in, implant type over the following time periods: 1998-2005; 2006-2010 and 2011-2015. Age, gender, indication and outcomes for each time period were examined and also trends with implant type over time. Results: There were 499 primary TAR procedures with an overall incidence of 0.5/105 population per year. The peak incidence of TAR was in the 6th decade. The mean age of patients undergoing TAR from 59 years in 1998-2005, to 65 years in 2011-15 (p<0.0001). The percentage of patients with inflammatory arthropathy was 49% in 1998-2005, compared with 10% in 2011-2015. Subsequent arthrodesis and infection rates appeared to be higher during the first time period. The female to male ratio also changed over time. The incidence of TAR increased overall during the study period (r= 0.9, p=<0.0001). This may be due to a broadening range of indications and patient selection criteria, in turn due to increased surgeon experience and the evolution of implant design. Conclusion: This study examines a large number of TARs from an established national arthroplasty database. The rate of TAR has increased significantly in Scotland from 1997 to 2015. Indication and patient age has changed over time and this could potentially impact outcomes after ankle replacement.

Full textAbstract:
About 10,000 ha of staked tomato are grown each year in the winter–spring season in southwest Florida. Tomatoes are produced with transplants, raised beds, polyethylene mulch, drip or seepage irrigation, and intensive fertilization. With the development of nutrient best management practices (BMPs) for vegetable crops and increased competition among water users, N recommendations must ensure economical yields, but still minimize the environmental impact of tomato production. The current University of Florida–IFAS (UF–IFAS) N fertilization rate of 224 kg·ha-1 (with supplemental fertilizer applications under specified conditions) may require adjustment based on soil type and irrigation system. Because growers should be involved in the development and implementation of BMPs, this project established partnerships with southwest Florida tomato growers. Studies evaluated the effects of N application rates on yield, plant growth, petiole N sap, pests, and diseases. Nine on-farm trials were conducted during the dry winter 2004–05 season. Treatments consisted of N fertilizer rates ranging from 224 to 448 kg·ha-1, with each trial including at least the UF–IFAS rate and the traditional rate. Although total yields were comparable among N rates, there were differences in size category. Nitrogen rates had little effect on tomato biomass 30 and 60 days after transplanting. Changes in petiole sap NO3-N and K concentrations were different between seepage and drip irrigation, but usually above the sufficiency threshold. It is important to consider the type of irrigation when managing tomato and determining optimum N fertilizer rates.

Statistically, Nigeria has a youth population of about 67 million, aged between 15 and 35 years. 42.2% of these young people are not gainfully employed while only 20% have more than the secondary school certificate. In order to bridge this gap, the Delta State Government developed the Delta ICT parks, a growing 21st century business, service and technology facility equipped to train, educate and encourage an entrepreneurial culture with sound human resource, that would drive development of an ICT knowledge based economy. This initiative, borne out of the Delta beyond oil is already in steady progress, enjoying the partnership of System Application Product (SAP) under the platform of Europe, Middle East and Africa (EMEA) that portends a global IT based future. The objective of this paper is to access the level of implementation and publicity, skill acquisition and degree of the impact of the initiative on employment generation in Delta State. The study, which adopted a survey design, applied three research questions and used oral interview and a Millennium Park Entrepreneurial Assessment Questionnaire (MPEAQ). The content validity was validated by experts from Entrepreneurial Skills Development and Human Resources Management of Delta State Polytechnic Ogwashi-Uku (DESPOG) with a test, re-test reliability coefficient of 0.82. A Sample of 350 was drawn using stratified random sampling technique from an undeterminable growing population comprising of secondary, tertiary education students, trainees and graduates of the programme. The simple percentage was used for data analysis. The findings revealed the need for the establishment of ICT parks with adequate awareness campaign. Also, that ICT skill acquisition is a panacea for employment generation in most societies. Recommendations were made based on findings on this model of employment generation through ICT in Delta State of Nigeria.

Aim. JSC RZD is one of the largest and most advanced companies in Russia who actively deploys and uses best practices in asset and risk management. In 2010, the railway industry initiated the project for the management of resources, risks and dependability at lifecycle stages of railway facilities (URRAN) that is currently under way. The aims of this paper are to overview the asset management tasks covered by URRAN; examine the marketed IT tools designed to address such problems; present the progress of the URRAN project in terms of process automation implemented by JSC RZD in light of the international best practice and the specificity of the Company. Methods. The preparation of this paper involved empirical and theoretical research. The authors analysed the URRAN project’s package of guidelines and regulations, public information on the globally available software products enabling asset management, as well as the program documentation of the EKP URRAN automated system. They analysed the functionalities and and engineering solutions used in the development of this automated system. The results of the EKP URRAN deployment and practical application by units and branches of JSC RZD were evaluated. Results. Asset management involves using Enterprise Asset Management Systems (EAMS) specially designed to suit the needs of specific companies or mass-produced “out-of-the-box” systems, e.g. SAP ERP, IBM MAXIMO, ABB AbilityТМ and SimeoTM that are examined in the paper. The EKP URRAN implements a single information space that is a decision support tool for the asset management system as it possesses the required regulatory and procedural resources, hardware and software assets intended for comprehensive management of assets and processes for the purpose of efficient railway service. In the future, the EKP URRAN is to become part of the Digital Platform for Risk and Traffic Safety Management deployed in JSC RZD and will comprise modules that implement dynamic predictive analytics models for the purpose of predicting undesirable events involving infrastructure and rolling stock that may disrupt traffic safety. Conclusions. Further development of the EKP URRAN will soon provide all levels of company management with an efficient tool that allows, in the context of limited resources, making substantiated managerial decisions and rational investment allocation. The EKP URRAN is an asset of JSC RZD designed to be used by the managers and specialists of various JSC RZD units. It can be implemented as a standalone IT product for the purpose of developing and deploying an asset management system in various railway companies.

Full textAbstract:
This paper investigates the impact of the technical size and organizational complexity of SAP/R3 projects on implementation effort. Traditional models for predicting software implementation effort tie measures of code size and programming complexity to development time. ERP projects shift a significant proportion of the implementation effort from code development to the parameterization of a pre-existing software package. At the same time, they move complexity from technical to organizational factors since they force companies to adapt to predefined work processes embedded in the software. This paper redefines the concepts of size and complexity for ERP projects and empirically verifies their impact on implementation effort. Specifically, project size is measured in terms of the number of SAP modules and submodules that are implemented, while complexity is defined as the organizational scope of the project in terms of users involved and overall company size. Hypotheses are tested on 43 SAP/R3 projects conducted in a cross-section of manufacturing companies. The findings show that both the technical size and organizational complexity of projects are relevant drivers of implementation effort. The results indicate that implementation effort not only grows with the number of modules and submodules that are selected for implementation, but that SAP is found to require increasing resources to be implemented in larger companies and for a higher number of users, thus indicating that, while there is a technical component of effort that is independent of the organizational breadth of the project, each user adds an organizational component of costs.

Full textAbstract:
Every organisation needs access to fast online data in order to meet increasing customer demands. As a result, the information architecture of a company, how it is designed, and how information is managed are very important. Because the amount of content is growing at a precipitous rate, in order to manage it with the greatest efficacy, an online content management system is recommended. The challenge for organisations is to implement and manage a dynamic content management system that is responsive to changing requirements, while providing a structure that contributes to organisational efficiencies. How a content management system is designed and implemented (e.g. with Office 365, SharePoint, G Suite, or SAP OpenText) determines its success. This paper discusses using Agile approaches for business content management systems, to ensure that they will be used to their full potential.This conceptual research paper looks into the current context of Enterprise Content Management (ECM) and the desirable qualities of an Agile approach. First, the literature review explores the definitions, elements, benefits, and recent trends around ECM. Then, the paper discusses Agile project management (APM) with some major characteristics and typical features. Thirdly, the paper describes how an Agile ECM system should be (e.g., takes advantage of the growing Internet, cloud services, and mobile computing). An Agile ECM can be developed with an APM or a hybrid approach (i.e. using an Agile software development process to create an Agile end product).This paper covers possible methodologies based on traditional and Agile software development approaches. These encourage a flexible development approach to ECM implementation, and promoting end user involvement and their needs. An ECM system should be dynamic enough to meet the demands of future organisational growth and the business environment. It should allow integration with other new software, including those in the organisation and those in the Cloud. Two methodologies (Scrum and MIKE2.0) are explained, along with their strengths and weaknesses. The recommendation is to synthesize them so that future implementations may take advantage of techniques from both. MIKE2.0 can ensure good information governance, while Scrum can provide an innovative team-based approach and user empowerment, which are highly useful for implementing Content Services rapidly.

Full textAbstract:
The investment decision was made last year, and after a time-consuming selection process and intensive negotiations, the contract with the general contractor was signed. The business segment Fixing systems of the fischer group of companies faced a significant investment in its logistics – the development of automation technology in the Global Distribution Center (GDC). According to the project schedule, the transition to the automated small parts storage with shuttle technology would take place in December of this year. It was mid-April, and therefore the right time for the Head of Logistics of the business segment fischer Fixing systems, Matthias Wehle, to describe the current status: Were all the important milestones achieved and would the subsequent steps ensure a smooth transition? The employees in the logistics got accustomed to changes over the years. Structural changes such as the introduction of SAP R/3 in early 2000 and the establishment of the automated high-bay warehouse in 2008 had been successfully implemented. It was the same with the continuous improvement process through the use of the fischerProzessSystem fPS. The introduction of pick-by-light technology for the picking of small sized products with high demand had worked well, too. But the last staff meeting about launch of the shuttle system had left with him a feeling of uncertainty. He could already feel the spirit of optimism from some of the employees triggered by the upcoming introduction of the new system. The majority, however, listened patiently and Mr. Wehle sensed insecurity among the employees – how does this change affect me? Up until now, management had used multiple channels to communicate information to the employees. But feedback from the workforce to those in charge was rather rare. And the logistics manager remembered that the use of pick-by-voice for picking had been stopped for a number of reasons. Now as a result of the largest investment in recent years, the GDC faced a drastic operational change. With this in mind, Mr. Wehle pondered over the issue of employee communication again and again. And they had eight more months in order to take action until December…

Full textAbstract:
Implementation of big water projects requires that their funders, contractors, and government officials will move projects forward ignorant of their potential social and environmental costs. Economist Albert O. Hirschman raised the issue of ignorance in a widely-read analysis of the factors driving the project process in Latin America, Africa, Asia, and southern Europe. This ignorance, which Hirschman referred to as ‘the hiding hand,’ led to creativity in the case of the San Lorenzo irrigation system in northern Peru, but had lethal consequences in the case of Guatemala’s Chixoy dam project. While Hirschman saw what he called ‘the hiding hand’ as accidental, examination of documents related to large hydraulic infrastructure projects in Peru and Guatemala suggests that in the late twentieth century it was systematically produced by resistance on the part of international financial institutions to addressing the broader political context for project development, or to adequately addressing potential social and environmental impacts early in the project process.

One of the main goals of the Virtual Observatory activities right now is to provide the simple and powerful access to the large existing astronomical datasets in the VO compatible way. That is why we want present the results of the recent development of Sternberg Astronomical Institute Catalogue Access Services (SAI CAS) project – the first and the only project in Russia, which provides on-line access to the major astronomical catalogues and different services on top of them. It is developed by a group of astronomers in a framework of SAI Astronet project, funded by Russian Foundation for Basic Research. SAI CAS is an open-source implementation of the general Catalogue access service (influenced by SDSS CASjobs & OpenSkyQuery projects), based on original algorithms and open-source software. We decided to build our own system providing an effective access to the major astronomical catalogues and different services including cone-searches and cross-matching of user data with hosted catalogues.

Purpose Energy supply delivered via various energy projects is an important aspect of energy security for India. Managing supply through various capacity additions for providing continuous electricity 24×7 by 2019 is a significant challenge for the country. In this context, there is a need to assess the present situation of energy generation from the traditional energy projects that are being installed for the purpose of capacity addition. Thus, the purpose of this paper is to develop an inquiry model based on situation-actor-process (SAP), learning-action-performance (LAP) for the Indian energy and power sectors to analyze the status of the supply side of energy security. Design/methodology/approach A SAP-LAP model is used to synthesize the situations of both the energy and power sectors. For both systems, inquiry- and matrices-based SAP-LAP models have been considered for this purpose. The situation is presented for various issues related to the execution of different types of energy projects. Actors in these sectors are classified by those who are responsible and engaged in the execution of various energy projects. For demonstration purposes, only a thermal energy project is highlighted in this case study. Based on the synthesis of SAP elements, various LAP elements are analyzed which leads to lessons that may be learnt from the case. Suitable actions are identified, followed by an assessment of their impact on the performance of the energy projects. Findings By developing a framework for a SAP-LAP model for the assessment of energy security, it was found that both sectors need more investment for their sustainable growth and that the actors identified should be proactive in their decision making. Decision making should be based on the sustainable management practices of life cycle management and life cycle costing for the better utilization of energy resources to strengthen overall energy security. Research limitations/implications The SAP-LAP analysis is used to explain the supply side of energy security in a managerial context, as applied in the case of the Indian energy and power sectors. However, some other quantitative multiple-criteria decision-making techniques like the preference ranking organization method for enrichment of evaluations, the complex proportional assessment of alternatives, the analytic hierarchy process or qualitative interactions assessment techniques such as interpretive structural modeling (ISM), total interpretive structural modeling (TISM) or the interpretive ranking process can also be explored for the development of an energy security framework. Practical implications The synthesis of SAP leads to LAP, which bridges the gap by suggesting improvement actions based on learning from the present situation of power supply, from actors in the industry and from existing processes. The model presents the situation of energy security in terms of the timely execution of energy projects and their impacts on the gross domestic product of the country. Social implications The framework for learning can provide information to the various stakeholders, investors and sector organizations inquiring about various issues related to energy projects and supporting the idea for energy security and sustainability. Originality/value The SAP-LAP model is a novel approach for analyzing the present status of energy supply performance in a single model, which can act as the support for decision making in conflicting situations, specifically the conflicting nature of the Indian energy and power sectors.

Full textAbstract:
Selective ablation of spinal neurons possessing substance P receptors (NK-1 receptors) using the selective cytotoxin conjugate substance P-saporin (SP-SAP) decreases hyperalgesia and central sensitization. The mechanisms by which NK-1 expressing neurons modulate the excitability of other dorsal horn neurons are unclear. Because the majority of NK-1 expressing spinal neurons project rostrally, it is possible that they are part of a spinal-supraspinal circuitry that contributes to descending modulation of excitability of spinal nociceptive neurons. We therefore determined whether ablation of spinal neurons that possess the NK-1 receptor altered descending systems that travel via the dorsolateral funiculus (DLF). Spontaneous activity and responses of dorsal horn neurons evoked by mechanical (von Frey monofilaments) and heat (35–51°C) stimuli were determined before and after transection of the DLF and were compared in rats pretreated with intrathecal application of vehicle or SP-SAP. In vehicle-treated rats, transection of the DLF caused a 233% increase in mean spontaneous activity of neurons and enhanced their responses to mechanical and heat stimuli, whereas these increases in excitation were blocked in rats pretreated with SP-SAP. Importantly, SP-SAP alone had no effect on spontaneous or evoked activity in the absence of DLF transection. These results demonstrate that spinal neurons expressing the NK-1 receptor appear to play a pivotal role in regulating descending systems that modulate activity of nociceptive dorsal horn neurons.

Subject area Public Sector Management and Strategy Study level/applicability This case will be useful for courses in information technology (IT) innovation, public–private partnership (PPP) and strategic management. However, the use of the case will differ on the basis of the target audience who could be students of master's course or executive development course. Detailed discussion can be done on co-innovation strategy followed in a public–private partnership and to understand how a PPP can be successful in enterprise solutions. Further, the understanding on how e-procurement and e-tendering solutions work can be gained through this case. This case should be positioned when the discussion for the planning strategy of IT innovation takes place. Case overview SAP was a market leader in enterprise application software and empowered people across the globe to work more efficiently. The e-procurement solution for OILGIAN was managed by SAP LABS India. OILGIAN entrusted SAP with the task to design and implement the e-tendering solution. SAP appointed Ramakrishna Potluri, Lead Consultant, SAP, to manage the design and implementation of the e-tendering module as a part of e-procurement solution for the public sector. The reporting and the security concerns were stated by OILGIAN, and Potluri reassured that his competent team would comply with the needs. The main predicaments that he was going through were that how best he could take the proposition forward. Should he create the innovative solutions in-house or co-create with the customers? Which business models should he follow for this public–private co-innovation to be a predecessor of successful projects? Expected learning outcomes The case illustrates the following objectives: to discuss the co-innovation strategy followed in a public–private partnership; to understand how a public–private partnership can be successful in enterprise solutions; and to understand how e-procurement and e-tendering solutions work.

This article discusses that it is a testament to the hard work and ingenuity of the engineers working in the space program that such complicated systems get launched successfully. To the people who study it professionally, risk is the probability, or frequency (probability per unit time), and the consequence (severity) of an undesired event, and the uncertainties associated with the estimated probabilities and consequences. NASA has adopted a “continuous risk management” process for all its programs and projects. This process begins with the identification and analysis of program or project risks that impact success criteria. The risk management process continues with risk analysis, planning, tracking, and control. All unacceptable risks are dealt with before a project or program can proceed. Probabilistic risk assessments (PRA) are useful in every phase of a mission life cycle, not just at design or before launch. A PRA performed in the design phase can help identify the risks associated with systems and components and with technological options.

Purpose Digital India, the flagship programme of Government of India (GoI) originated from National e-Governance Project (NeGP) in the year 2014. The programme has important aspect of information security and implementation of IT policy which supports e-Governance in a focused approach of Mission Mode. In this context, there is a need to assess situation of the programme which covers a study of initiatives and actions taken by various actor involved and processes which are responsible for overall e-Governance. Therefore, the purpose of this case study is to develop a Situation-Actor-Process (SAP), Learning-Action-Performance (LAP) based inquiry model to synthesize situation of information security governance, IT policy and overall e-Governance. Design/methodology/approach In this case study both systematic inquiry and matrices based SAP-LAP models are developed. Actors are classified who are found responsible and engaged in IT policy framing, infrastructure development and also in e-Governance implementation. Based on a synthesis of SAP components, various LAP elements were then synthesized then which further led to learning from the case study. Suitable actions and performance have also been highlighted, followed by a statement of the impact of the efficacy i.e. transformation of information security, policy and e-Governance on the Digital India programme. Findings On developing the SAP-LAP framework, it was found that actors like the Ministry of Electronics and Information Technology of the Govt. of India secures a higher rank in implementing various initiatives and central sector schemes to accelerate the agenda of e-Governance. Actions of other preferred actors include more investments in IT infrastructure, policy development and a mechanism to address cyber security threats for effective implementation of e-Governance. It was found that actors should be pro-active on enhancing technical skills, capacity building and imparting education related to ICT applications and e-Governance. Decision making should be based on the sustainable management practices of e-Governance projects implementation to manage change, policy making and the governmental process of the Indian administration and also to achieve Sustainable Development Goals by the Indian economy. Research limitations/implications The SAP-LAP synthesis is used to develop the case study. However, few other qualitative and quantitative multi criteria decision making approaches could also be explored for the development of IT security based e-Governance framework in the Indian context. Practical implications The synthesis of SAP leads to LAP components which can bridge the gaps between information security, IT policy governance and e-Governance process. Based on the learning from the Situation, it is said that the case study can provide decision making support and has impact on the e-Governance process i.e. may enhance awareness about e-services available to the general public. Such work is required to assess the transparency and accountability on the Government. Social implications Learning based on the SAP-LAP framework could provide decision making support to the administrators, policy makers and IT sector stakeholders. Thus, the case study would further help in addressing the research gaps, accelerating e-Governance initiatives and in capturing cyber threats. Originality/value The SAP-LAP model is found as an intuitive approach to analyze the present status of information security governance, IT policy and e-Governance in India in a single unitary model.

Full textAbstract:
Important institutional lessons learned in the course of the San Diego smart call box field operational test are presented. These lessons relate both to the conduct of the field test itself and to requirements for deployment of intelligent transportation systems similar to smart call boxes. The institutional issues were identified through review of project documents, interviews with participants, and the experience of the evaluator as a participant in the project. Issues were analyzed by preparing summaries that included a description and discussion of each issue, an assessment of its seriousness, identification of the organizational participants who raised it, a discussion of ways to avoid or mitigate any problems identified, and a list of actions to resolve the issue in the event of system deployment. Major institutional lessons include the potential impact of institutional arrangements on basic system concepts, the importance of involving potential users in the definition of system concepts and detailed design specifications, the need for quantitative market research to establish the potential profitability of intelligent transportation systems, the need for an adequate institutional infrastructure for deployment, and the importance of project organization schemes that minimize the number and complexity of formal agreements among participants.

Full textAbstract:
In this study we investigated how perceived switching costs and benefits influence user resistance as a major cause of information systems project implementation failure, from the perspectives of individual emotions and traditional values. We used structural equation modeling and hierarchical regression analysis to analyze data from 256 potential users of a new information system. Participants were employed by a telecom operator in China. Results indicated that positive emotions played a partial mediating role in the relationship between perceived switching costs and benefits and user resistance. Further, user traditionality moderated the influence of perceived switching costs and benefits on user resistance. These findings have theoretical implications and we suggest practical ways in which managers can alleviate user resistance.

Full textAbstract:
An overview of the Tren Urbano project in San Juan, Puerto Rico, is presented. Phase 1 will be a 17-km rail rapid transit line from Bayamon to Sagrado Corazon in metropolitan San Juan. The line is standard gauge, third-rail-powered, 750-Vdc, rail rapid transit, fully grade-separated. An initial fleet of 64 cars was ordered, and an option for 10 more has been exercised. The project has been bid as a design-build-operate-maintain effort, with Siemens Transportation Systems, Inc., as the prime contractor. Work has been divided into six segments and bid by local contractors. Through the Systems Turnkey and Test Track contract, Siemens is responsible for all systems elements, including cars, power supply, signals, train control and communications, the yard and shop, and about 2 km of main line with two passenger stations. Systems elements are described, with emphasis on their origin in various countries in addition to the United States. The need for Buy America compliance is mentioned. Some car-borne equipment was designed and initial units were built overseas, with most production being done in U.S. plants owned or contracted by the suppliers. By using international sources, Siemens was able to be the lowest bidder and yet provide a quality system to meet the contract requirements.

Abstract. The 2015 Paris Agreement set a goal to pursue a global mean temperature below 1.5 °C and well below 2 °C above preindustrial levels. Although it is an important surface hydrology variable, the response of snow under different warming levels has not been well investigated. This study provides a comprehensive assessment of the snow cover fraction (SCF) and snow area extent (SAE), as well as the associated land surface air temperature (LSAT) over the Northern Hemisphere (NH) based on the Community Earth System Model Large Ensemble project (CESM-LE), the CESM 1.5 and 2 °C projects, and the CMIP5 historical RCP2.6 and RCP4.5 products. The results show that the spatiotemporal variations in those modeled products are grossly consistent with observations. The projected SAE magnitude change in RCP2.6 is comparable to that in 1.5 °C, but lower than that in 2 °C. The snow cover differences between 1.5 and 2 °C are prominent during the second half of the 21st century. The signal-to-noise ratios (SNRs) of both SAE and LSAT over the majority of land areas are greater than 1, and for the long-term period, the dependences of SAE on LSAT changes are comparable for different ensemble products. The contribution of an increase in LSAT to the reduction of snow cover differs across seasons, with the greatest occurring in boreal autumn (49–55 %) and the lowest occurring in boreal summer (10–16 %). The snow cover uncertainties induced by the ensemble variability are invariant over time across CESM members but show an increase in the warming signal between the CMIP5 models. This feature reveals that the physical parameterization of the model plays the predominant role in long-term snow simulations, while they are less affected by internal climate variability.

This article discusses the recent development in “cognitive computing” technology. Unlike expert systems of the past, which required inflexible hard-coded expert rules, cognitive computers interpret unstructured data (sensory information, images, voices, and numbers), navigate through vast amounts of information, learn by experience, and participate in dialogues with humans using natural language to solve extremely complex problems. The U.S. Defense Advanced Research Projects Agency is funding a program called SyNAPSE (Systems of Neuromorphic Adaptive Plastic Scalable Electronics) to develop machine technology that will function like biological neural systems. IBM, Hughes Research Labs, and several universities are working on this program. The aim is to build an electronic system that matches a mammalian brain in function, size, and power consumption. It would recreate 10 billion neurons and 100 trillion synapses, consume one kilowatt (same as a small electric heater), and measure less than 2,000 cubic centimeters. Several other projects are also under way to apply cognitive technology to robotics, cars, and production systems.

This case describes how Siemens Power Corporation, a Richland, Washington, USA-based manufacturer of nuclear fuel assemblies, came to adopt and implement SAP's R/3 application suite, the world's leading enterprise resource planning (ERP) package. The case introduces the reader to the type of decision making related to an ERP adoption and implementation and provides some interesting examples of factors which may influence actual decisions and outcomes. Among other things, the case touches on the following issues: the relationship between restructuring (re-engineering) and software adoption and implementation, the choice of package software, the pros and cons of alternative implementation approaches (‘big bang’ versus ‘phased'), the selection of hardware and the value of consultants. By January 1999 Siemens Power Corporation's (SPC's) restructuring project was more than 2 years under way. To SPC's top management's great relief, the company had made major progress ever since SPC's German parent Siemens AG hired a consulting team to help SPC get back on its path towards profitability. In particular, the largest and riskiest of its individual restructuring subprojects – SPC's SAP R/3 implementation – seemed on the way to becoming a success.

VLC (Visible Light Communications) have been recently proposed as a new form of wireless communications. The VLC advantages are its usage of the spectrum of visible light which is not licensed; additionally, it gives high data rates, protects the user against espionage and does not suffer from interference of the electromagnetic spectrum. One of the main techniques used in VLC is HACO-OFDM (Hybrid Asymmetrically Clipped Optical - Orthogonal Frequency Division Multiplexing), which offers a high spectral efficiency. However, one of its main problems is its high PAPR (Peak-to-Average-Power Ratio). This article presents a study and simulation of Clipping, CE-POCS (Constellation Extension – Project Onto Convex Sets), OPS (Orthogonal Pilot Sequences) and SAP (Simple Amplitude Predistortion) techniques for the reduction of the PAPR in HACO-OFDM systems. The simulation results show that the SAP technique gives the best results in PAPR reduction without significant degradation in the BER (Bit Error Rate).

Abstract This article reports a comparative analysis of the media’s political agenda setting capacity in 27 European media systems, aimed at testing the hypothesis that the magnitude of this phenomenon is moderated by factors such as development of the press markets, journalist professionalization, strength of public television or political pluralism. The empirical analysis relies on data collected by the expert survey European Media Systems Survey, the World Association of Newspapers, the European Audiovisual Observatory, and the research project Providing an Infrastructure for Research on Electoral Democracy in the European Union (PIREDEU). Results show that political agenda setting is perceived as more common in press markets in which newspapers work as means of horizontal communication (and are, as subsystem, politically imbalanced), but that journalist professionalization and strength of public broadcasting systems foster political agenda setting effects.

We discuss safety principles of autonomous driving road vehicles. First, we provide a comparison between principles and experience of autonomous or automatic systems on rails and on the road. An automatic metro operates in a controlled and well-defined environment, passengers and third persons are separated from driving trains by fences, tunnels, etc. A road vehicle operates in a much more complex environment. Further, we discuss safety principles. The application of safety principles (e.g. fail-safe or safe-life) is used to design and implement a safe system that eventually fulfils the requirements of the functional safety standards. The different responsibility of human driver and technical driving system in different automation levels for autonomous driving vehicles require the application of safety principles. We consider, which safety principles have to be applied using general safety principles and analysing the relevant SAE level based on the experience from projects for the five levels of automated driving as defined by the SAE. Depending on the level of automation, the technical systems are implemented as fail-silent, fails-safe or as safe-life.

Full textAbstract:
As part of the ‘Bridging the Language Gap’ project undertaken with 86 State and Catholic schools across Queensland, the language competencies of Indigenous students have been found to be ‘invisible’ in several key and self-reinforcing ways in school system data. A proliferation of inaccurate, illogical and incomplete data exists about students’ home languages and their status as English as an Additional Language/Dialect (EAL/D) learners in schools. This is strongly suggestive of the fact that ‘language’ is not perceived by school systems as a significant operative variable in student performance, not even in the current education climate of data-driven improvement. Moreover, the National Assessment Program – Literacy and Numeracy (NAPLAN), the annual standardised testing regime, does not collect relevant information on students’ language repertoires and levels of proficiency in Standard Australian English (SAE). Indigenous students who are over-represented in NAPLAN under-performance data are targeted through ‘Closing the Gap’ for interventions to raise their literacy and numeracy achievements (in SAE). However, Indigenous students who are EAL/D learners cannot be disaggregated by system data from their counterparts already fluent in SAE. Reasons behind such profound language invisibility are discussed, as well as the implications for social inclusion of Indigenous students in education.

This article presents the results of a student survey conducted in 2004 at Tallinn University within the framework of the project “School as a developmental environment and students' coping.” The questionnaire was completed by 3,838 7th, 9th and 12th grade students from 65 Estonian schools. The project arose from the need to prevent students from school drop-out and repeating grades. The main hypothesis was that by modifying a school's social climate, one can either help or disable the development of students' constructive coping strategies and thus support, or not, students' academic success. Our most important conclusion is that the school climate parameters, especially the school value system and teachers' attitudes toward students as perceived by the latter, influence students' optimistic acceptance of life, their psychological and physiological well-being, and academic success.

Full textAbstract:
Leadership has been recognized as a major factor in project success and this has been empirically validated throughout many fields. However, chief executive officer leadership style has seldom been discussed in depth in the context of enterprise resource planning (ERP) project success. In this study a survey was carried out with 368 Taiwanese companies that had previously implemented ERP systems over a 1-year period. Three transformational leadership styles – charisma, individual consideration, and intellectual stimulation – are discussed. The results indicate that only a charismatic leadership style has a substantially positive effect on organizational performance, especially through the successful implementation of ERP. Managerial implications and suggestions are discussed based on findings.

Abstract Fidgeting may be a motor sign reflecting self-regulation processes in patients with social anxiety disorder (SAD) and depressive patients. Since SAD co-occurs with comorbid depression, the question arises whether fidgeting is a disorder-unspecific phenomenon or a specific and therefore diagnostically relevant sign of depression. 33 SAD patients with (n = 12) and without (n = 21) depression from the Social Phobia Psychotherapy Research Network project were compared regarding their nonverbal behavior. Four video sequences of a psychotherapy session with each patient were analyzed using a standardized system for the analysis of nonverbal behavior by two independent, certified, blind raters. SAD patients with comorbid depression exhibited significantly more (number/minute) irregular movements, but fewer (number/minute) repetitive movements than SAD patients without depression. Irregular movements, which reflect less structured motor behavior, are associated with comorbid depression in SAD. In contrast, in SAD without depression, more structured repetitive movements were prominent. Thus, irregular movements represent a diagnostically relevant behavior for comorbid depression among SAD patients.

Full textAbstract:
San José 520 is a Classic period hamlet of single-family residences in the urban periphery of Teotihuacan, just beyond the southeast edge of the city. Three burial features were associated with one of the residences, AF2. One of the features contained the burial of a single adult, another the successive burials of eight adults and one neonate, and the third held a neonate. We analyzed 29 bone and enamel samples from the adults for bioapatite phosphate oxygen-isotope composition; we also considered isotopic data for another five bone samples analyzed in a separate project. The isotopic results suggest a pattern of birth in the Teotihuacan region and then movement in early childhood to a “relocation” region, the geographic location of which is unknown. Later, probably in adolescence, the individuals returned to live, and eventually die, in San José 520. Without knowing more about the occupation of the relocation region, it is difficult to say what concerns or beliefs underlay this unusual but long-established settlement system.

Full textAbstract:
A double-isotope autoradiographic technique was used to evaluate CBF and glucose metabolism 2 days after a subarachnoid hemorrhage (SAH) in rats with lesions in the lower brainstem. Lesioning in the mesencephalon of the ascending catecholamine pathways from locus ceruleus and from the A1 and A2 nuclei, or lesioning in the medulla oblongata of the ascending fibers from A1 and A2, prevents the development of the global changes in flow and metabolism seen in normal animals post SAH. Also the focal low-flow areas with markedly elevated deoxyglucose uptake, which can develop in normal animals 2 days post SAH, were not seen in the lesioned animals after the SAH. The findings indicate that the A1 and A2 nuclei, which project to the hypothalamus–pituitary, are essential for the flow and metabolic changes after an SAH. The lesions per se did not change baseline flow and metabolism as compared with sham-lesioned animals.

Implementing an ERP project is a political process. This paper starts with a literature review of organizational politics and its implications to the implementation of ERP systems. The Political Strategies Framework which categorizes different ePolitics strategies in the cases is introduced. The framework is applied in the later sections of the paper to case study data from two companies, one in the US and one in Italy, that both implemented a SAP Enterprise Planning Systems (ERP) with very different outcomes. The discussion highlights the political dynamics in each case and the way in which the framework can help us understand these differences. The conclusion section discusses the differences between the political dynamics in each case and the implications from the findings to broader issues of research on ERP implementation and politics.

Activation of the cardiac sac motor pattern by the neuropeptides proctolin and red pigment-concentrating hormone."

Full textAbstract:
1. The cardiac sac motor pattern consists of slow and irregular impulse bursts in the motor neurons [cardiac sac dilator 1 and 2 (CD1 and CD2)] that innervate the dilator muscles of the cardiac sac region of the crustacean foregut. 2. The effects of the peptides, proctolin and red pigment-concentrating hormone (RPCH), on the cardiac sac motor patterns produced by in vitro preparations of the combined stomatogastric nervous system [the stomatogastric ganglion (STG), the paired commissural ganglia (CGs), and the oesophageal ganglion (OG)] were studied. 3. Bath applications of either RPCH or proctolin activated the cardiac sac motor pattern when this motor pattern was not already active and increased the frequency of the cardiac sac motor pattern in slowly active preparations. 4. The somata of CD1 and CD2 are located in the esophageal and stomatogastric ganglia, respectively. Both neurons project to all four of the ganglia of the stomatogastric nervous system. RPCH elicited cardiac sac motor patterns when applied to any region of the stomatogastric nervous system, suggesting a distributed pattern generating network with multiple sites of modulation. 5. The anterior median (AM) neuron innervates the constrictor muscles of the cardiac sac. The AM usually functions as a part of the gastric mill pattern generator. However, when the cardiac sac is activated by RPCH applied to the stomatogastric ganglion, the AM neuron becomes active in antiphase with the cardiac sac dilator bursts. This converts the cardiac sac motor pattern from a one-phase rhythm to a two-phase rhythm. 6. These data show that a neuropeptide can cause a neuronal element to switch from being solely a component of one neuronal circuit to functioning in a second one as well. This example shows that peptidergic "reconfiguration" of neuronal networks can produce substantial changes in the behavior of associated neurons.

The development of unmanned air vehicles (UAVs) has been very rapid recently. The wide accessibility of UAVs has unlocked a great potential for the malicious or accidental damage or destruction of property or other aircraft in flight. UAVs can be used for espionage, contraband, and the trafficking or transport of arms and hazardous materials. Every month sees a growing number of reports of incidents that involve remote-controlled UAVs operated for aerial video recording. These incidents justify undertaking research into minimizing the hazards which UAVs may potentially cause. A concept was developed for a solution dedicated to this problem and comprising an integrated modular anti-UAV system for application in commercial (civilian) markets in the areas of security of mass events, strategic enterprises, and critical strategic infrastructure in Poland. The proposed system is intended to incapacitate any UAVs that breach a predefined air space and bring the incapacitated UAVs safely to the ground. The project is developed jointly by the Institute of Armament Technology at the Military University of Technology (Warsaw, Poland) and Polish company Ellipsis Sp. z o.o.

AbstractStructuring the early design phase of automotive systems is an important part of efficient and successful development processes. Today, safety considerations (e.g., the safety life cycle of ISO 26262) significantly affect the course of development. Preliminary designs are expressed in functional system architectures, which are required to form safety concepts. Thus, mapping tasks and work products to a reference process during early design stages is an important part of structuring the system development. This contribution describes the systematic creation and notation of the functional safety concept within the concept phase of development of an unmanned protective vehicle within the research project aFAS. Different stages of preliminary design and dependencies between them are displayed by the work products created and used. The full set of functional safety requirements and an excerpt of the safety argument structure of the SAE level 4 application are presented.
