Pinto, de Mendonça José Rogério 1963. "Business impacts of CRM implementations." Thesis, Massachusetts Institute of Technology, 2002. http://hdl.handle.net/1721.1/8467.
Full textIncludes bibliographical references (leaves 75-76).
This thesis aims at examining CRM implementations and at obtaining theoretical and practical evidence to three questions: ** What patterns emerge in successful CRM implementations, and general factors that prevent organizations from achieving expected results in such projects; ** What business benefits and impacts (e.g., return on investment, customer value, and redesign of business processes), are typically observed in CRM initiatives; ** How companies rearrange their organizational structures to, maximize the benefits of CRM. To accomplish these goals the author conducted a review of available literature, arid then interviewed members of 3 companies that implemented CRM and 2 system integrators with comprehensive experience in implementation of CRM. This practical experience intended to confirm the findings obtained through the literature review. The 3 companies researched are market leaders in the Financial Service Industry in Latin America. Consistently, the System Integrators interviewed actively serve the same industry. The major findings of this work are the following: ** Technology components as well as vendor selection is secondary as a key success factor; ** Companies usually do not reorganize themselves due to CRM implementations. Structure models; seems to be much more dependent on intrinsic cultural aspects; ** Observed business benefits have a high degree of variation, depending much on the situation before the implementation - all researched cases were considered to be successful. Although the sample analyzed is not sufficient to establish generalizations, due to its size and to the impossibility of obtaining reliable numeric or quantitative data, we report our results and interpret as a contribution to the growing body of evidence. Most of the conclusions are consistent with the literature review findings, with the exception of the observed absence of 'business cases' in the analyzed companies. The literature claims that elaboration of detailed business cases is critical, whereas in the analyzed companies a less rigorous, but nevertheless detailed, planning was sufficient to ensure success. Apart from the limitation of the size of the researched sample, due to the relative newness of the theme, part of the literature reviewed was composed by white papers published by CRM vendors, management consulting firms, and independent research and advisory companies. The research suggests that such implementations have important and lasting effects on the business. It also indicates that the magnitude of the business impacts are intrinsically dependent of the realities of particular companies, and cannot be generalized even within the specific financial services sector. Most of conclusions are based on qualitative analysis. since the number of cases, complexity and variability of the implementations, prevent from generating statically sound analysis. It would be valuable if this research could be extended through other industry sectors, in Latin America, or alternatively to encompass financial service companies from other regions.

Jimerson, Diont'e Lashaun. "Technology Impacts on Teaching Third Grade Math Using iPads." Thesis, Northcentral University, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10980258.
Full textThis research study focused on how technology-based tools have changed the 21st century education arena in elementary school mathematics classes. The research highlighted the inner city schools where many students in the class are achieving below state standards set for third grade level. The research question asked to what extent do students have a higher level of engagement in math classes in which iPads and other technologies are used? Technology continued to advance in 21st century classrooms where students are daily participants in teaching and learning with acquired experience using technology tools to accelerate their learning experience. Children are technology users with a passion for texting, web surfing, playing interactive games, social media, and more. The research methodology was data collection of achievement levels, using a quantitative method. The quantitative process for the research project supplemented the greater understanding of student achievement growth from integrated iPads in a third-grade math class in inner city schools in Chicago. The test was completed by the students, and the scores were automatically updated on the public website. The students had two hours to complete the test, and the students’ information was kept confidential. The students that were taught using technology outscored the students that were not taught using technology. The recommendation was to implement technology in all schools and create a challenging curriculum. The final recommendation for teaching with technology included the beneficial factors.

Controlled-release drug-delivery systems enable efficient and defined administration of therapeutic agents to target tissues. However, ultimate drug distribution and pharmacologic effect are determined by target tissue pharmacokinetics. In muscular tissues, complex architecture that is further augmented by dynamic motion and contraction can alter the pharmacokinetics and deposition of locally delivered macromolecules. We developed a system and applied a quantitative schema to investigate the impact of controlled mechanical loads applied to skeletal and cardiac muscle tissue on intramuscular transport of locally delivered drug. In a series of studies, we examined how the interaction between architectural configuration and functional mechanics alters the transport of drugs across both physicochemical and binding properties. We correlated these pharmacokinetic effects with characteristic parameters in the physiologic range of the tissue to derive mechanistic insight into the fundamental structural and dynamic elements that underlie these effects. While previous studies have revealed the unilateral scaling of substrate uptake with mechanical influences, we elucidated an architecturally defined pharmacokinetic setpoint whereby maximal drug penetration corresponds with optimal muscle function. Our findings elucidate basic biologic design in muscle that optimizes the interface between tissue and its physical environment. The unique insights from our investigations have broad impact on current understanding of the pharmacokinetic influences of biologic form and function, and elucidate new clinical strategies for controlled release and local delivery of a wide range of therapeutic compounds to mechanically active tissues.

This paper investigates the adoption of the Direct Planting System (DPS) in Brazil, a rural technology whose adoption is widely promoted because of benefits, both private and social, it allegedly delivers. This study relies on recent evidence on the determinants of adoption of this technology to investigate its impacts using a large panel of microdata of farm units in the state of Sao Paulo, Brazil. We explore variations in geographic locations and soil characteristics to construct instruments for adoption in order to identify the impacts of this adoption in agricultural outputs, in land allocations and in other production decisions. Although evidence of productivity gains remains uncertain, we do find significant impacts of DPS adoption in land allocations and production decisions.
Este trabalho investiga a adoção do Sistema de Plantio Direto (SPD) no Brasil, uma tecnologia rural bastante promovida devido aos benefícios, tanto privados como sociais, que alegadamente traz. O trabalho baseia-se em evidências recentes sobre os determinantes da adoção desta tecnologia para investigar seus impactos utilizando-se de um grande painel de microdados de unidades de produção agrícola no estado de São Paulo, Brasil. Nós exploramos variações em localizações geográficas e características de solos para construir instrumentos para a adoção e assim identificar os impactos dessa adoção na produção agrícola, nas alo- cações de terras e em outros indicadores da organização produtiva das fazendas. Embora as evidências de ganhos de produtividade permaneçam inconclusivas, nós encontramos impactos significativos da adoção de SPD na alocação de terras e nas decisões de produção.

This thesis presents research about the potential business impacts of the Semantic Web. The concept of the Semantic Web is an expansion of the Web for computers, enabling them to comprehend the meaning of information. In addition, Semantic Web Services (SWS), the emerging convergence of Web Services with the Semantic Web, is the next major generation of the Web (and of the Internet), in which e-services and business communication become more knowledge-based and agent-based. The study arose out of a technology review of the Semantic Web and its current adoption. Following further analysis and research into business cases involving Semantic Web applications, the author focused specifically on the system integration business in an effort to understand the potential business impacts of the Semantic Web for system integration. In the system integration field, there are various trends for companies thinking about adopting the Semantic Web into the real business world. In this thesis, I offer answers to two questions: Why do system integrators need the Semantic Web, and how they should go about adopting it?

During the last two decades, traffic congestion in the U.S. has increased from 30% to 67% of peak period travel. Further, current research shows that measures taken within transportation systems, such as adding capacity, improving operations and managing demand, are not enough to keep congestion from growing worse. With the worsening traffic, the vehicle's fuel consumption and pollutant emissions will inevitably increase. As such, this thesis aims to quantitatively evaluate the energy and environmental impacts of worsening traffic on individual vehicles and the U.S. light-duty vehicle fleet, as well as to design feasible measures beyond transportation systems to offset theses impacts. The fuel consumption and emissions of different vehicle types under different driving situations provide the basis for analyzing the energy and environmental impacts of worsening traffic. This thesis defines the concept of "driving segments" to represent all possible driving situations which consist of vehicle speed, operation patterns and road types. For each vehicle type, its fuel consumption and emissions in different "driving segments" can be developed into a matrix by ADVISOR 2004, the vehicle simulation tool. Combining the "driving segments" vehicle performance matrices with the model for traffic congestion, the energy and environmental impacts of worsening traffic on individual vehicles can be examined.
(cont.) Based on these impacts, this thesis compares the performance of different vehicle types for both today's and tomorrow's traffic situations. Meanwhile, the on-road fuel economy of each vehicle type has also been calculated to update EPA's fuel economy rating by taking worsening traffic into consideration. Combining the "driving segments" vehicle performance matrices with a set of models for fleet population, vehicle technology, driving behavior and traffic congestion, the energy and environmental impacts of worsening traffic on the U.S. light-duty vehicle fleet can also be examined. Through sensitivity analysis, this thesis investigates the effects of altering vehicle choice, developing vehicle technology and changing driving behavior on offsetting the fuel consumption and emissions of the U.S. light-duty vehicle fleet caused by worsening traffic through 2030. It is concluded that promoting the market share of advanced vehicle technologies (Hybrids mainly) is the most effective and most feasible method.

Full textIncludes bibliographical references (leaves 90-93).
This thesis assesses the problem of adverse environmental impacts due to the use of Portland cement and structural steel in the construction industry. The thesis outlines three technology and policy strategies to mitigate these impacts: 1. Reduce consumption; 2. Select materials to minimize impacts; and 3. Explore alternative new materials that have lesser impacts. The main findings and recommendations in each of these areas are as follows: Reduce Consumption: While absolute consumption of materials will grow with a growing population, recycling and reuse of structural members can reduce use of virgin material. Since recycling is already widely practiced, reuse of structural members is the primary means of further reducing consumption. Barriers to reuse can be eliminated by establishing design standards and regulations for reuse of structural sections, and creating functioning markets for re-useable sections. Select materials to minimize impacts: While designers are keen to select materials with minimum impacts, they do not have appropriate education or tools for the purpose. Standardization and simplification of Life Cycle Assessment (LCA) tools, and education of designers are identified as the main areas for improvement. The main recommendations are: i) standardize LCA tools; reduce the number of impact categories, make the categories understandable and incorporate uncertainty data and ii) establish programs for educating designers about materials selection tools. Alternative new materials: New materials with lesser impacts need to be explored. The main recommendations in this area are: i) conduct life cycle assessments of new materials to determine environmental credentials over their lifetime and
(cont.) ii) establish appropriate policies enabling market adoption of alternative new technologies. The life cycle assessment of magnesia cement (a mix of cement containing reactive magnesium oxide) is carried out. The assessment concludes that magnesia cements could be a more environmentally friendly alternative than ordinary Portland cement. In summary, this thesis shows that the current consumption trends are not sustainable. The large volumes of construction materials consumed annually may lead to irreversible changes in the natural environment. Alternatives to current practices urgently need to be found.

Full textAlthough there is a large investment made in technology in our public and private schools each year, there has been comparatively little effort made into understanding the impact of that technology on our students. This study examines the relationship between student boredom, media multitasking, and distraction in an effort to understand the impact of media multitasking on our students. To examine this, a mixed methods design was utilized, consisting of a memory recall experiment, student interviews, and a survey instrument. This study found that laptops are preferred over iPads for both focus and academic reasons, and it discovered classroom environments and teaching methodologies that caused distraction to occur as well as strategies employed by students to attempt to overcome distraction. Ultimately, this study did not find an impact on academic performance as assessed by a memory recall experiment. As a result, this study contributes significant knowledge into technology distraction at the high school level as well as modifications that can help improve student focus.

Increasing amounts of intermittent renewables have led to zero and negative priced electricity at times of peak wind and solar production. The volatility added to the grid by renewables and low prices at peak production create a demand for flexible energy supply and present an opportunity for energy arbitrage. Nuclear reactors in the United States are inflexible when compared to fossil generators, and batteries may store energy at peak renewable production, albeit at a high capital cost. Thermal energy storage coupled to nuclear reactors may both increase nuclear flexibility and capitalize on price volatility, benefitting the economics for the struggling nuclear industry. This research maps the option space for constructing a crushed rock thermal energy storage (TES) system coupled to a light water reactor and employs a modification of the GenX capacity expansion model to evaluate the economic. Historic demand and renewable resource availability from ERCOT were used to illustrate the benefit of crushed rock TES with an increasingly restrictive CO₂ emission constraint. Parametric variations were used to address uncertainty in performance estimates. Crushed rock TES was found to be beneficial under favorable conditions, reducing the average price of electricity from $81/kWh (without TES) to $73/kWh (with TES) at a system marginal cost of $5/kWh-heat and emissions constraint of 100 g CO₂/kWh-electric, a nearly 10X reduction of current emissions. Unfavorable conditions resulted in a price reduction from $81/kWh to $78/kWh with the same cost estimates and carbon constraint. The investment cost of enabling the ability for nuclear generation to couple to crushed rock TES was also found to significantly affect the system's favorability and effect on electricity prices.

Full textThe emergence of Information Technology (IT) is increasingly influencing the socio-economic and physical landscape of cities. It has also resulted in development of predominantly IT based industrial cities. These cities have the opportunities and challenges with respect to the development of their socioeconomic, infrastructural and environmental conditions because of the influence of the IT based industrial activities. This article therefore pertains to the analysis of the perspective impacts of IT industry and allied activities on the development of an emerging IT industrial activity based city. For this purpose, Pune, an emerging IT city in India was considered as a case study. Survey research methodology and a system dynamics modelling approach were employed to measure the influential socio-economic, infrastructural and environmental parameters of the city by considering the city as a system. This research shows that the location of IT industry and associated functions contribute significantly towards the socio-economic development of a city in terms of IT industry export, State Gross Domestic Product (SGDP), per capita SGDP, employment generation, to name some relevant aspects. However, there would be a reduction in satisfaction level of the infrastructure and an increase in environmental stress in the system, which needs strategic attention. Further, the model results and scenarios can facilitate evolving of feasible policy and strategic guidelines for the wholesome development of such cities.

Full textEm um contexto de crescimento populacional e econômico, as projeções de demanda para produtos agrícolas no futuro são expressivas. Ao mesmo tempo, a agricultura já exerce pressão significativa nos recursos naturais do planeta. Como consequência, é preciso obter maior oferta de produtos e, ao mesmo tempo, limitar o impacto ambiental da atividade agrícola. Essa tese avalia o papel da infraestrutura e uso de Tecnologia da Informação e Comunicação (TIC) no desenvolvimento sustentável da agricultura. Baseando-se na literatura empírica sobre impacto de infraestrutura no desenvolvimento, dois modelos estatísticos foram criados. O primeiro analisa os impactos do uso de internet e telefones celulares na produtividade de cereais utilizando uma regressão em painel de efeitos fixos para 212 países no período entre 1990 e 2014. O segundo utiliza um modelo Propensity Score Matching para avaliar o impacto da instalação de tecnologia 3G no desmatamento de municipios localizados na região da Amazônia Legal brasileira. De acordo com a metodologia e dados utilizados, os resultados indicam que um crescimento no uso da internet pode positivamente impactar a produtividade de cereais em um país. Para o caso do uso de telefones celulares os resultados são inconclusivos. Finalmente, de acordo com o modelo, há indicações de que municipios que receberam a tecnologia 3G no período estudado tiveram taxas de desmatamento reduzidas quando comparadas a municipios similares que não receberam a tecnologia.

The concrete pavement network in the United States plays a crucial role in the economy by enabling the transport of people and goods, but it also leads to resource consumption and environmental impacts. This thesis is fundamentally motivated to reduce the impact that concrete pavements have on climate change. The principal methodology that is used is life cycle assessment (LCA), which comprehensively includes all five primary phases of the life cycle: materials extraction and production, pavement construction, pavement rehabilitation, the use phase, and end-of-life recycling and disposal. This work informs the reduction of life cycle greenhouse gases (GHGs) through a three-pronged approach to: 1) comprehensively quantify GHG emissions for structures representing all primary pavement types in the US, 2) establishes a benchmark for GHG emissions from all concrete pavements in the US constructed annually, and 3) identifies five reduction strategies and measures the GHG reduction that is obtainable through these strategies, both at the project-level for different road classes and at the national level. This provides a portfolio of GHG reduction options to national and regional policymakers, transportation agencies, and pavement engineers.

Full textSom ett resultat av ständiga ansträngningar att förbättra såväl prestanda som spektrumeffektivitet för mobila system, definierar 3GPPs standardiseringsforum nya krav på arkitektur och funktionalitet. Dessa är avsedda att säkerställa långsiktig utveckling (explicit definierat som konceptet “Long-Term Evolution (LTE)”, samt framtida konkurrenskraft för både 2G och 3G som radioaccess-teknologier. Tidigare diskussioner rörande effektivitet inom LTE har fokuserat på allmänna antaganden vad gäller kontrolldata för signallering och övergripande systemprestanda. Dessa har i sin tur baserats på erfarenheter från existerande mobilsystem. När standardiseringen inom 3GPP mognar uppstår nu ett behov av att undersöka hur olika tjänster inom LTE påverkas, av såväl hur man använder den kontrollinformation som finns tillgänglig, som av basala algoritmer for schemaläggning av resurser. Denna rapport undersöker påverkan från lägre protokoll-lagers kontrollinformation på nerlänken hos olika paket-kopplade tjänster inom ett radioaccessnät för LTE. Resultaten visar att användandet av ROHC (som packar kontrollinformation för protokollen RTP/TCP/IP), är det ensamt viktigaste bidraget till minskad kontrollinformation i relation till informationsbitar för paketstorlekar upp till c:a 1kB. För större paket är vinsten med ROHC dock försumbar. Kontrollinformation för protokoll – inkluderat data avsett för AMR-tal-ramen, RLC/MAC-protokollen, samt CRC – utgör för övrigt en stor del av kontrollinformationen relativt informationsbitar, oavsett paketstorlek och packning av kontrolldata. Tjänster som kräver paketstorlekar på över c:a 1 kB kräver uppskattningsvis samma mängd energi per informationsbit, oavsett andelen kontrollinformation.

In the coming years and decades, shifts in weather, population, land use, and other human factors are expected to have an impact on the occurrence and severity of landslides. A landslide inventory database from Switzerland is used to perform two types of analysis. The first presents a proof of concept for an analogue method of detecting the frequency in landslide activity with future climate change conditions. Instead of relying on modeled precipitation, it uses composites of atmospheric variables to identity the conditions that are associated with days on which a landslide occurred. The analogues are compared to relevant meteorological variables in MERRA reanalysis data to achieve a success rate of over 50% in matching observed landslide days within 7 days. The second analysis explores the effectiveness of machine learning as a technique to evaluate the likelihood of a slide to create high damage. The algorithm is tuned to accommodate unbalanced data, extraneous variables, and variance in voting to achieve the best predictive success. This method provides an efficient way of calculating vulnerability and identifying the spatial and temporal factors which influence it. The results are able to identify high damage landslides with a success of upwards of 70%. A machine-learning based model has the potential for use as a policy tool to identify areas of high risk.

The large number of unskilled people provided cheap labour and was used as easy replaceable tools. Employees have since become companies' most expensive '''assets''. The Internet was originally designed for military applications. The US military wanted a network that could withstand a terrorist attack and stilI work if important communication areas had been destroyed. The Internet, also known as the giant network of networks, has become a major catalyst for electronic business. The Internet caused the shape of companies to change and the way they conduct business. For example the Intemet enabled companies to be run from home and changed the old companies' structures. Sending data via a network is a lot faster and less expensive than making a telephone call or sending a messenger. Businesses have become more dependent on the Internet to generate revenue. E-commerce refers to the buying and selling of goods and services on the Internet and reduces the cost of doing business. The down side is that companies are also more exposed to inherent security risks. New technology with old methods of working is also no longer feasible. Many clerical tasks disappear and both the job functions of staff and the supervisory functions and procedures change. Information technology (IT) is increasing productivity, and thus, for a given output, a smaller number of people are employed. Increasing numbers of workers are retrenched when still in mid-career because labour is a most expensive commodity. The reduction in overheads and improved response of modem administrative systems increase the opportunities for organisations of all sizes to compete on an international level.

The United States has a large supply of parking and with the adoption of autonomous vehicles, the demand for these spaces could change dramatically. Parking is among the most prevalent land uses occupying up to 31% of urban area. It is estimated that there are 3.4 to 8 parking spaces for each car in the US yielding 800 million to 2 billion spaces that could cover an area the size of West Virginia (Chester, Horvath, & Madanat, 2010). With fully autonomous vehicles expected on the consumer market by 2020, the $30 billion parking industry will experience enormous changes as cars evolve. This thesis models the effects of autonomous vehicles on the financial performance of urban parking garages. The future of parking and autonomous vehicles will be anything but smooth or certain, and this work harnesses the power of uncertainty through repeated random number simulation in financially modeling autonomous vehicles' impacts on parking garages. The results indicate that parking in the short term is a risky investment and in the longer term may not be a viable asset. As the only class of real estate explicitly built for vehicles, they have a high degree of exposure to changes created by autonomous vehicles. This is illustrated by significantly negative net present values and minimal returns of the simulation outputs. This exposure will continue to grow as the stock of parking spaces increases with minimum parking requirements for new construction. Recommendations from this research would be to limit new supply of parking to allow for greater utilization of existing stock, more beneficial use of urban land, and better use of construction and financial resources.

Full textThe aim of this study was to investigate how the use of profilers impacted the performance of multi-threaded applications. This study was undertaken in the framework of a project for Edument AB, creators of one of the profilers investigated in this study. Specifically, the study aimed to find out what additional overhead can result in profiling multi-threaded applications, with regards to CPU use, memory use, and additional time taken to complete execution. The paper hypothesised that the selection of data that each profiler recorded would impact the performance, with those that recorded a very large amount of detail about the application being profiled would introduce a higher overhead.A selection of five profilers was made, each profiler offering a range of features and functionality, and a test application was written to simulate a multi-threaded application. A very lightweight application, referred to as the monitoring application, was also written which recorded the overhead each profiler used, along with the overhead of the test application and the time taken to run. Essentially, each profiler was itself profiled by the monitoring application, ensuring consistent overhead data was gathered for each profiler.The results of the study showed that the choice of profiler can have a substantial impact on the performance of the application being profiled. One profiler resulted in execution of the test application taking 513% as much time to run, and adding an overhead of 1400% memory use. After analysing this data, there appeared to be a correlation between what features the profilers recorded and the overhead, consistent with the hypothesis put forward at the beginning of the study.
