This article presents the results of a research project on the adoption of B2B e-commerce (B2Bec) by Canadian manufacturers. The study provides an analysis of the characteristics of organizations which have adopted B2Bec technologies and attempts to outline the features that differentiate adopters from non-adopters. The results of a preliminary analysis show the existence of three distinct B2Bec adopter types: non-adopters, partial-adopters, and full-adopters. Leadership-related variables appear to be the most important determinants of adoption followed by benefits analysis.

Every year, thousands of new technological ideas are conceived. An ability to innovate these ideas continues to be critical in surviving the current business world. This study identifies and empirically assesses the characteristics of technological innovativeness. A research model based on the existing literature on consumer innovativeness is thus presented. The model is tested via a survey instrument from a population of earlier adopters of mobile money services in Ghana and analyzed using ANOVA and independent sample t-test techniques in SPSS. The results showed that early adopters of technology are younger, novelty seekers, and more likely to have good employment and opinion leadership than late adopters. The study contributes to diffusion literature by providing further empirical evidence on the distinctive characteristics of early and late adopters of technology and posits that contrary to past research, independent judgment making of an individual does not affect innovativeness.

Testo completoAbstract (sommario):
Progressive development in the field of information technology (IT) has brought in remarkable changes in the products as well as methods of payment and settlement system in the banking sector. In India, various types of payment systems are functioning apart from the traditional payment systems where the instruments are physically exchanged and settled manually. Smart cards are a new form of retail payment instrument, installed to facilitate retail transactions through electronic means. In 1999, the Reserve Bank of India issued guidelines to the banks regarding introduction and usage of smart cards. Smart cards are currently being issued by several banks in India which have tied up with Financial Information Network and Operations Ltd. (FINO). The IDBI bank has introduced its smart card called MoneySmart; Corporation Bank has issued CorpSmart; and Bank of India has issued its e-purse cards. PNB, SBI, ABN Amro, ICICI Bank, Bank of Baroda and some other banks have also launched smart card-based banking solutions (Kaur & Kaur, 2008). The main objective of this study is to identify the factors that may vary between the adopters and the non-adopters of smart cards in Indian banks. Banks that have adopted the cards may have different characteristics from those that have not yet adopted the cards. In other words, with the exploration of various characteristics of the banks, the study tries to differentiate between the adopter and non-adopter categories of the banks regarding smart cards with respect to their profitability, size, competitive advantage, efficiency, asset quality, financing pattern, diversification, cost of operations, etc. The empirical results evidently reveal that the banks providing smart cards differ in their characteristics from that of the banks that have not yet adopted it. It shows that the banks that adopted smart cards are larger in size, more efficient, pay lesser wages, and have more industry advantage and thus, in terms of some characteristics, outperform the non-adopter banks.

Andrews, Verity A. "Genetics and genomics in nursing : what are the characteristics of genetic nurse adopters and nurse opinion leaders in genetics and genomics?" Thesis, University of South Wales, 2012. https://pure.southwales.ac.uk/en/studentthesis/genetics-and-genomics-in-nursing(237c7d78-1001-4039-9c54-e694eae69dc9).html.
Testo completoAbstract (sommario):
Background. Aspects of genetics/genomics are increasingly being incorporated into medicine. Nurses are crucial in helping transform healthcare through genomic nursing (Loud, 2010). However the integration of genetics/genomics into nursing education has been sporadic (Dodson and Lewallen, 2011). Influencing its uptake into practice may be via nurses who are already utilising genetics/genomics in their practice (adopters) and nurses who may lead the way and encourage others (opinion leaders) to do likewise. Identifying the characteristics of such adopters and opinion leaders within nursing may provide useful information for more wide-scale detection of these individuals to support a strategy for the inclusion of genetics/genomics into nursing practice. Methods. Five change behaviour theories were used to inform the study including the Theory of Planned Behaviour and the Diffusion of Innovations. A mixed methods approach was taken over two phases. In Phase 1 experts in the field of genetics/genomics and nursing were contacted to gain a consensus on four potential genetic indicators of adoption (GIAs), which would identify a nurse who had adopted genetics/genomics. In Phase 2, oncology nurses and practice nurses completed a questionnaire to identify the characteristics and demographic indicators of nurse genetic adopters and opinion leaders. Results. A consensus (>75%) was achieved for all four GIAs to be included as indicators of adoption of genetics/genomics within nursing practice (Phase 1). Individuals identified (in Phase 2) were subcategorised into six different groups, including genetic adopters and opinion leaders. There were 18 identifying features that defined an adopter, with some of the main features being Openness to Experience (p<0.001), seeing the relevance of genetics/genomics to their patient group (p<0.001) and talking to colleagues about genetics/genomics (p<0.001). There were six features that identified an opinion leader, including academic achievement (p=0.007), level of perceived influence over others (p<0.001) and being high on the opinion leadership scale (p<0.001). Two of the biggest barriers to incorporation by nurses were lack of time for adopters and a lack of local study sessions for opinion leaders. Conclusion. It has been identified that nurses can be categorised in terms of their relationship to genetics/genomics, through a number of distinguishing characteristics. It will be important to further identify and clarify these and other characteristics through the development of additional tools. These data can inform approaches to promote a greater integration of genetics/genomics into nursing practice, ultimately improving patient healthcare.

Testo completoAbstract (sommario):
O Brasil tem posição de destaque na produção agrícola mundial. A adoção de tecnologias que permitam preservar os recursos naturais e produzir alimento em quantidade e com qualidade é importante para o desenvolvimento do agronegócio. Dentre as tecnologias, destaca-se a Agricultura de Precisão – AP. O objetivo deste trabalho foi investigar a adoção da AP e os fatores relacionados a tal decisão dos produtores rurais no estado do Rio Grande do Sul. Com este propósito, foram coletados dados através do envio de questionário para produtores rurais usuários da AP. A análise descritiva dos dados permitiu caracterizar os adotantes e a adoção das ferramentas de AP entre os produtores rurais, enquanto a análise fatorial seguida de regressão linear múltipla foram empregadas para verificar a percepção dos adotantes quanto aos atributos tecnológicos da AP. Os resultados mostram o crescimento da adoção da AP e que o tempo médio de adoção é de 4,3 anos. Os adotantes de AP possuem grau de escolaridade elevado, utilizam diversas fontes de informação, têm a renda predominantemente agrícola e cultivam grandes áreas de terra. As ferramentas de AP mais adotadas no cultivo de grãos (soja, milho e trigo) são a amostra de solo georreferenciada (ASG), a aplicação em taxa variada de corretivos e fertilizantes (ATV) e o sistema de direcionamento de barra de luz (BLZ). Constatou-se que a adoção da AP é altamente dependente da terceirização de serviços de AP. O número de ferramentas de AP adotadas está positivamente associado ao tamanho da área cultivada, anos de experiência com AP, renda agrícola e investimento em AP. Os atributos tecnológicos da AP – vantagem relativa, visibilidade, compatibilidade e experimentação – determinam 48% da satisfação do adotante de AP, sendo o fator de maior potencial explicativo a vantagem relativa da tecnologia. Evidenciado o crescimento recente da adoção da AP entre os produtores rurais no Brasil, emergem oportunidades de pesquisas que venham a contribuir com a indústria e instituições de fomento na difusão da AP.Brazil plays an important role in world agricultural production. The adoption of technologies which allow the increase of food production with improving quality in addition to natural resources conservation is important for agribusiness development, and Precision Agriculture – PA stands out as an option to aid the achievement of these goals. The aim of this work was to investigate the Adoption of PA, as well as the factors related to its adoption by farmers in Rio Grande do Sul, Brazil. With this purpose, an online survey was sent to PA adopters. Descriptive analysis allowed the characterization of the PA adopters and the identification of the most adopted PA tools, while factor analysis followed by multiple linear regression were used in order to verify users’ perception regarding PA technology attributes. The results show a PA adoption growth and an average time of adoption of 4.3 years. PA adopters have a high level of formal education, use several sources of information, have a predominantly agricultural income and cultivate large areas. The most adopted PA tools used for growing soybeans, maize and wheat are grid soil sampling, variable rate application and lightbar guidance. It was noted that PA adoption is highly dependent on PA services. The number of PA tools adopted is positive associated with the size of cultivated areas, years of PA use, agricultural income and investments in PA. PA technology attributes – relative advantage, observability, compatibility and trialability – determine 48% of the PA adopters’ satisfaction, being relative advantage of technology the factor of greatest explicative potential. The recent growth of PA adoption by Brazilian farmers shows emerging opportunities for research development which may contribute with industry and government institutions on PF diffusion.

Testo completoAbstract (sommario):
To remain relevant, even the successful social networks need to evolve. Vertical Social Networks (VSN) are the response of this, satisfying people who are seeking more niched and personalized content. However, this is a highly competitive environment where taking advantage of the first mover advantages is crucial for the future success. This study concerns diffusion of innovations and segmentation according to the technology adoption lifecycle to investigate how a VSN can reach user growth by understanding their current users better. We have built this study upon an explorative case study of a case company operating in the VSN landscape providing their users with an application. Building on extensive literature research, theory, surveys and conducting interviews, differences in user characteristics were identified. Theoretical and empirical evidence was further analyzed based on user behavior and level of satisfaction. Our recommendations suggest that considerations for different phases of the diffusion journey has to be made by targeting the appropriate users as this is vital for satisfying the existing users, and for reaching new ones.För att bibehålla relevans, måste även de mest framgångsrika sociala nätverken utvecklas. Vertikala Sociala Nätverk (VSN) är svaret på detta, genom att tillfredsställa människor som söker mer nischade och personifierat innehåll. Detta landskap är dock präglat av hög konkurrens där vikten av att vara först på marknaden är avgörande för framtida framgång. Denna studie belyser Innovationsspridning och segmentering enligt Technology Adoption Lifecycle för att undersöka hur ett VSN kan nå användartillväxt genom att förstå sina nuvarande användare bättre. Vi har genomfört en undersökande fallstudie av ett företag inom VSN branschen som bistår sina användare med en applikation. Baserat på tidigare forskning, teori, enkäter och intervjuer identifierades olikheter i karaktärsdrag hos deras användare. Teoretiska och empiriska bevis beträffande olikheter i karaktärsdrag analyserades och diskuterades vidare baserat på användarbeteende och nivå av tillfredsställelse. De föreslagna rekommendationerna innefattar att ett övervägande för olika faser av diffusionsresan måste göras för att tilltala lämpliga målgrupper, då detta är avgörande för att tillfredsställa befintliga användare, och för att nå nya.

This study examines in terms of Adlerian Life Style as revealed through Early Recollections, actual and perceived Birth Order, and Family Atmosphere the personality characteristics of Korean adults adopted as infants in the United States of America. Eight Korean subjects participated in a structured, tape recorded interview. Each subject reported four early recollections and/or dreams. Transcripts of these interviews were given to a panel of expert Adlerian judges who collectively analyzed and interpreted the gathered information. A composite life style summary could be formulated by combining common themes and personality characteristics. Results indicate several common life style themes and personality characteristics. The most commonly shared attributes were expecting to be hurt, wanting to be accepted and important, and viewing others in a negative sense.

Testo completoAbstract (sommario):
Utilizing ECLS-K:2011 data, this study compares adopted and biological children to account for the role of heritable characteristics in explaining the relationship between family environments and children's cognitive skills. I find that cognitive skills do not differ across adopted and biological children after adjusting for the systematic differences between them. I also find that the relationship between family environment and children's cognitive skills does not differ across adopted and biological children. Taken together, these results suggest that the relationship between family environment and children's cognitive skills is not spurious.

Testo completoAbstract (sommario):
Despite large investment by higher education institutions in technology for faculty and student use, instructional technology is not being integrated into instructions in the higher education institutions including medical education institutions. While diffusion of instructional technologies has been reached a saturation pint with early adopters of technology, it has remained limited among mainstream faculty. This investigation explored instructional technology patterns and characteristics of medical school faculty as well as contributing factors to IT adoption. The primary focus was to explore differences between early adopting faculty and mainstream faculty based on Rogers’
diffusion of innovations and adopter categories theories. A mix-method research design, a quantitative methodology(survey) in conjunction with qualitative methodology(in-dept interviews) was employed for the purpose of gathering data about characteristics and adoption patterns of medical school faculty who are early adopting and mainstream. A hundred and fifty-five teaching faculty from basic science and clinical science disciplines at a Faculty of Medicine in a state university completed the survey. In-dept interviews were conducted with faculty who are early adopting and mainstream. The findings provided an evidence for similarities between adoption patterns of medical school faculty and other higher education faculty
relatively new tools associated with instruction were not adopted by majority of the faculty. As expected, some differences were found between early adopters and mainstream faculty in terms of individual characteristics, adoption patterns, perceived barriers and incentives to adoption and preferred methods of learning about technology and support. Implications of the findings for instructional technology policy and plans were reported.

The internet has become a common tool in daily life; this tool can come in a variety of forms, including search engine, content website, online shopping, audiovisual services and social network. Yet, aside from the success of products or services themselves, which people play a significant role in the dissemination of these services or products, and thus accelerate the development of new trends? The main purpose of this study is to learn about the characteristics of early users of Facebook via the diffusion of innovation theory, using its findings to provide reference for social network development and workers in the field of network marketing. In addition to the diffusion of innovation theory, this study also explores the history of the internet, developments of Web 2.0 and Facebook, and characteristics of early users. This research adopts a quantified approach and uses a questionnaire survey to collect data, analyzing users who have used Facebook for at least one year. Results show that early users of Facebook were mostly highly educated and had relatively high income, but the capacity to accept innovation is not related to gender and age. In addition, these users had relatively high socioeconomic status, were more able to bear risk, and had higher aspirations. Furthermore, these people came in contact with relatively more forms of media, and interacted more frequently with others. However, this study also found that wealth is not necessarily positively related to innovation, which is consistent with findings of Rogers (2006) in the diffusion of innovation theory.

This chapter focuses on the strategies adopted by plants and animals in order to live, at least for part of their life cycle, in urban environments. There is a discussion of the concepts of specialist and generalist species. This is followed by an examination of the strategies adopted by plants, including a consideration of concepts such as the C-S-R model (competitors, stress tolerators, and ruderal species). Then urban avoiders, urban adapters, urban exploiters (also known as human associates), and urban obligates (also known as human obligates) are introduced. These strategies are illustrated by examples of animals living in (or avoiding) urban environments around the globe. In the summary, the five characteristics shared by many plants and animals in urban environments are presented.

The chapter examines the legal nature of intangible property and the distinction between choses in action and choses in possession. It discusses the characteristics of choses in action, particularly the quality of assignability. It then looks at the ways in which intangibles can be dealt with and transferred, legal and equitable assignment, sub-participation, novation, the mechanism of attaching the intangible to a physical item, and transfer by means of a declaration of trust. Finally it discusses the idea adopted by the Uniform Commercial Code of the United States, of creating ‘hybrid rights’.

Testo completoAbstract (sommario):
This book explores the relationship between competition law and economic development, which takes on growing importance as more and more developing countries have adopted competition law in recent years. The work tackles two principal questions. The first is whether competition law enforcement promotes growth, which helps to determine how seriously developing countries should enforce their competition laws. The second is how developing countries should craft their competition law rules in light of the need to incorporate development concerns, the need to reflect the special economic characteristics of developing countries, and the need to improve the administrability of competition law rules to suit the enforcement capacity of developing country authorities.

In September 2015, the UN General Assembly adopted the Sustainable Development Goals as an integral part of the 2030 Agenda for Sustainable Development. The Sustainable Development Goals mark the most ambitious effort yet to place goal setting at the center of global governance and policy. This book is the first book addressing global governance through goals, asking three sets of questions. First, the book studies in detail the core characteristics of goal setting in global governance, asking when it is an appropriate strategy in global governance and what makes global governance through goals different from other approaches such as rule making or norm promotion. Second, the book analyze under what conditions a goal-oriented approach can ensure progress toward desired ends; what can be learned from other, earlier experiences of global goal setting, especially the Millennium Development Goals; and what governance arrangements are likely to facilitate progress in implementing the new Sustainable Development Goals. Third, the book studies the practical and operational challenges involved in global governance through goals in promoting sustainability and the prospects for achieving such a demanding new agenda. The book revealed that the approach of “global governance through goals”—and the Sustainable Development Goals as a prime example—is marked by a number of key characteristics, but none of those is specific to this type of governance. Yet all these characteristics together, in our view, amount to a unique and novel way of steering and distinct type of institutional arrangement in global governance.

In 1907, William Jennings Bryan described the proposed constitution for Oklahoma as “the best constitution in the United States today.” An enduring characteristic of Oklahoma’s constitution has been its faith in direct democracy and its root in Progressive Era politics. This book traces the historical formation and constitutional development of the state of Oklahoma. It provides commentary and analysis on the intent, politics, social and economic pressures, and the legal decisions that shaped and enhanced the Oklahoma constitution since it was adopted in 1907. The text gives a broad understanding of state constitutional law within the context of Oklahoma’s constitutional evolution.

Testo completoAbstract (sommario):
This chapter describes the taxonomy of colonial Hydrozoa. Siphonophores are pelagic organisms that can be found the whole year round, sometimes in a characteristic season, inshore and offshore at all latitudes and depths. As in all hydrozoans, they carry tentacles equipped with stinging cells (nematocysts), which are used by the colony to immobilize and kill their prey. The chapter covers their life cycle, ecology, and general morphology. It includes a section that indicates the systematic placement of the taxon described within the tree of life, and lists the key marine representative illustrated in the chapter (usually to genus or family level). This section also provides information on the taxonomic authorities responsible for the classification adopted, recent changes which might have occurred, and lists relevant taxonomic sources.

Testo completoAbstract (sommario):
Staying current with latest developments in the field of patient care is now universally considered to be a standard of care. The same standards have not been adopted in medical education, however, and many educational techniques used to train physicians are now outdated. This chapter reviews the evidence in medical education with respect to quality of three critical elements: the teacher, the process, and the learner. Students and faculty have different perceptions regarding the characteristics of effective teachers. Modern teaching methods no longer stress lecture-based sessions, but include techniques such as interactive learning and blended learning. Simulation is also an effective tool for learning technical skills, and for crisis and team training. When technological tools are used, they should be designed to enhance the learning experience. A number of studies show that learner engagement is the key factor in the learning process.

Testo completoAbstract (sommario):
The “mad cow” saga provides useful insights into the complexities that surround public communication on food safety issues. The first part of the chapter describes the most important scientific characteristics of bovine spongiform encephalopathy (BSE) and its human counterpart, variant Creutzfeldt-Jakob disease. The second section offers an account of the unfolding of public communication before, during, and after the BSE crisis, including the diverse positions adopted by different countries and the legal reforms enacted to improve risk communication. The final part provides an analysis of the key features of the mad cow crisis: the importance of trust and transparency, the uncertainties that can characterize scientific information, the effects of cognitive bias, and the role of cultural context. All these factors contributed to both the amplifying and downplaying—depending on place and time—of the BSE risk in the public mind.

AbstractThis study assesses the feasibility of electric three-wheelers as moto-taxis in Dar es Salaam, Tanzania from a socioeconomic and technical point of view. The analysis is based on three pillars: (i) the acceptance of users (the moto-taxi drivers) for adoption, (ii) the vehicle specifications incl. battery type and size, and (iii) the role of the charging infrastructure. Findings are based on data from empirical field-work; methods used are qualitative and quantitative data analysis and modelling. Main findings include that moto-taxi drivers, who we see as most important adopters, are open towards electric mobility. They request however that vehicles should have similar driving characteristics than their current fuel-vehicles. As the market is very price sensitive, keeping the vehicle cost is of high importance. A high potential to lower these costs is seen by offering opportunity charging spots around the city. If such an infrastructure is being implemented the combination with suitable, cost competitive vehicles makes the transformation of the vehicle market towards electrification possible.

Testo completoAbstract (sommario):
In this chapter, the characteristics and the role of the early adopters and early majority are reviewed from the life cycle perspective following the VCR case study. Both of these groups of consumers purchase a mature or more advanced product at a reasonable price. Their adoption demonstrates that the product performance has enough future possibilities. On the other hand, manufacturers should expand their manufacturing facilities quickly because the demand starts growing dramatically. The early adopters (13.6 percent) are almost six times as many as innovators (2.3 percent) and the early majority (34.1 percent) is about 2.5 times as many as early adopters. Once a diffusion process starts, the spread is very rapid in the first group.

Schools have become places filled with digital tools. Despite this fact, school leaders find technology planning to be an area of relative weakness. This chapter describes the experiences of four school leaders who adopted an unfamiliar strategy for making technology decisions. The leaders participated in a series of semi-structured interviews. Two leaders displayed characteristics of early adopters of the innovative planning strategy and two displayed characteristics of early majority users of the strategy. Profiles of the two types of leaders are presented. The aspects of the planning strategy that differentiated it from more familiar planning strategies for these leaders are discussed.

Testo completoAbstract (sommario):
The penetration of the Internet and opportunities involving information and communication technologies (ICTs) have occurred at an escalating rate within the private sector. This has caused governments and public sector organisations around the globe to become aware of their potential and consequently utilise them; thereby triggering investments in e-services (Choudrie et al., 2004a). However, the e-services offered by governments are much more than simple automation. E-services are meant to dramatically improve all areas of government activities: from democratic participation using online voting to improving the efficiency of citizen interactions with the government by providing online government services (Barc & Cordella 2004).Other countries around the globe are undertaking various e-government measures. Similar to them, the United Kingdom (UK) government is also undertaking steps that ensure it is progressing in accordance with these countries. For this purpose, the introduction and experiences of utilising a number of government services that are offered electronically via the ‘Government Gateway’ in the UK is pertinent. These e-government services include council tax bills and accounts, housing benefits, child benefit claims, carer’s allowance, jobs online, state pension forecasts, self assessment of tax and tax credits, landweb direct, and the national blood services (Government Gateway, 2004). This is in contrast to the traditional method, whereby access to government services was undertaken by the citizens visiting ‘physical, brick foundation’ locations. Therefore this novel phenomenon offers a great amount of convenience and ease for citizens’ use (Government Gateway, 2004). However, it is not known whether the citizens of the UK are aware of such services. Further, questions are still emerging concerning whether the citizens are actually adopting the newly offered services. Therefore the initial aim of this chapter is to examine citizens’ awareness and adoption of e-government initiatives, specifically the Government Gateway in the United Kingdom. Since these services have been recently introduced, an investigation is needed to study if the demographic characteristics and home Internet access are affecting the awareness and adoption of these services. Therefore the second aim of this chapter is to examine the affect of the citizens’ demographic characteristics and home Internet access on the awareness and adoption of e-government services. To fulfill these aims, this study undertook an empirical examination of the awareness and adoption of the Government Gateway amongst UK citizens. This research offers a contribution to various stakeholders including the government agencies who could require a distinction to be drawn between the adopters and non-adopters of e-government services. That is, from the results of this research the government agencies could better understand in a simpler and detailed manner, the problem of low adoption. This could allow the formulation of a strategy that promotes awareness and diffusion. The chapter begins with a brief discussion of research undertaken on the citizens’ adoption of e-government services and a brief overview of the Government Gateway and its purpose. The findings are then presented and discussed. Finally, a conclusion to the research is provided. It is important to mention that the research methodology for this chapter is already presented and discussed in previous chapters. Therefore, this chapter does not include research methodology and only presents empirical data in the form of tables.

Testo completoAbstract (sommario):
In 801, Harun Rashid offered Charlemagne a water clock, the like of which was inexistent in all of Europe at that time; the King’s court thought that a little devil was hidden inside the clock. In the 1930s, King Abdulaziz of Saudi Arabia had to convince his people that the radio was not the making of the devil and that it could in fact be used to broadcast and spread the Quran. In 2003, the Arab region is found to be still lagging in modern technologies adoption (UNDP, 2003). Thus, in a little more than 11 centuries, the Arabs were transformed from leaders to adopters, then to late adopters as far as technologies are concerned. The Arab world is taken to mean the 22 members of the Arab League, accounting for more than 300 million people with an economy of 700 billion dollars. Although most Arabs practice Islam, they represent less than one third of all Muslims. The Arab world is often thought of as economically prosperous due to its oil resources; yet its total GDP is lower than that of Spain (UNDP, 2003). Arab countries share language and culture but differ in size, geography, demographics, government type, etc. In terms of spending in and use of IT, statistics portray the Arab world as far from being up-to-date (UNDP, 2003). This article raises the question of whether existing research models are appropriate to explain this delay. If certain characteristics proper to the Arab culture play an important role in explaining the delay in IT adoption, then we anticipate the answer to be that no existing model is able to adequately study the IT adoption phenomena in the Arab world.

Testo completoAbstract (sommario):
Evidence exists that citizens’ demand for pay-to-use e-government services is highly price-elastic. But research on citizens’ adoption of e-government remains almost entirely pre-occupied with contexts wherein it is implicit that citizens would not face any monetary cost implications. The fact that Technology Acceptance model (TAM) and Perceived Characteristics of Innovating (PCI) do not factor in potential adopters’ monetary cost perceptions is a plausible reason for such bias in research efforts. The paper posits a model wherein the value perceived by a citizen in government-to-citizen (G2C) online channel, and traditional public service delivery channel are antecedents of his or her intention to use the online channel. The model was tested in the context of the rail ticketing service of Indian Railways (a Department of India’s federal government). Results support the hypothesized paths, and offer useful managerial guidance to encourage citizens’ adoption. The paper discusses the prospect of certain adverse consequences for public administration and citizens, which could be linked to e-government and user charges, and ways to mitigate them. Research implications are also discussed.

Testo completoAbstract (sommario):
The proliferation of technology-enhanced learning environments and digital learning resources in formal educational institutions (both K-12 and higher education) has led to a corresponding interest in improving the cost-efficiency related to developing and deploying such materials within these institutions. In the e-learning industry, which has been primarily concerned with training in corporations and the military, this issue is approached through standardization of digital learning material in the form of learning objects. The Sharable Content Object Reference Model (SCORM) has emerged as the predominant approach to standardization among early adopters of learning object technology. While SCORM might aim at being agnostic with respect to pedagogical approaches, there is some concern that SCORM-based learning objects would not be well suited to all of the pedagogical approaches desired within formal educational contexts - particularly within those emphasizing social aspects of learning and inquiry-based learning. An alternative standard that attempts to describe use of learning objects more broadly and with greater flexibility is that of the IMS Learning Design (LD). We analyze the implications of the SCORM and LD specifications for the particular pedagogical domain of technology-enhanced inquiry learning. Our analysis builds on the extensive research conducted on technology supports for inquiry learning. We focus on a specific technology-enhanced inquiry science environment that has been designed through years of classroom-based research: The Web-based Inquiry Science Environment (WISE). Several important characteristics of the WISE pedagogical approach serve to illuminate our discussion on learning objects and standards. Learning activities are carried out in a social or collaborative context within WISE; they occur primarily in a classroom setting; they are student-centered, and they are concerned with ill-structured problems. These characteristics are not unique to inquiry science projects, but rather represent an approach to pedagogy and curriculum design that is increasingly common within formal education.

Testo completoAbstract (sommario):
This study tested the attributes of the theory of diffusion of innovation empirically, using Automatic Teller Machines (ATMs) as the target innovation. The study was situated in Jos, Plateau state, Nigeria. The population comprised banks customers in Jos who used ATMs. The sampling frame technique was applied, and 14 banks that had deployed ATMs were selected. Cluster sampling was employed to select respondents for the study. Data collection instrument was a structured questionnaire administered to 600 respondents of which 428 were returned giving 71.3% return rate. Principal Factor Analysis, and Multiple Regression were the analytical techniques used. The demographic characteristics of the respondents revealed that most of them were students and youths. From the factor analysis, it was revealed that the respondents believed in their safety in using ATM; that ATMs were quite easy to use and fit in with their way of life; that what they observed about ATMs convinced them to use it and that ATM was tried out before they use it. The constructs Relative Advantage, Complexity, Compatibility, and Trialability were all found to have a significant impact on the Attitude towards ATM, which in turn had a significant impact on the Intention to use it. Relative Advantage and Compatibility had almost the same weight of impact on Attitude; while Observability had the highest impact on attitude. To increase the diffusion of ATMs, it was recommended that banks should ensure enhanced salience of ATM to customers’ needs, greater compatibility of ATM to customers banking norms and lifestyle, less complex and easy to use system and opportunity for adopters to experiment with the system before using ATMs.

The ANSYS-CFX software is used to simulate NASA-Mark II high pressure air-cooled gas turbine. The work condition is Run 5411 which have transition flow characteristics. The different turbulence models are adopted to solve conjugate heat transfer problem of this three-dimensional turbine blade. Comparing to the experimental results, k-ω-SST-γ-θ turbulence model results are more accurate and can simulate accurately the flow and heat transfer characteristics of turbine with transition flow characteristics. But k-ω-SST-γ-θ turbulence model overestimates the turbulence kinetic energy of blade local region and makes the heat transfer coefficient higher. It causes that local region temperature of suction side is higher. In this paper, the compiled code adopts the B-L algebra model and simulates the same computation model. The results show that the results of B-L model are accurate besides it has 4% temperature error in the suction side transition region. In addition, different turbulence characteristic boundary conditions of turbine inner-cooling passages are given and K-ω-SST-γ-θ turbulence model is adopted in order to obtain the effect of turbulence characteristic boundary conditions for the conjugate heat transfer computation results. The results show that the turbulence characteristic boundary conditions of turbine inner-cooling passages have a great effect on the conjugate heat transfer results of high pressure gas turbine. ANSYS is applied to analysis the thermal stress of Mark II blade which has ten radial cooled passages and the results of Von Mises stress show that the temperature gradient results have a great effect on the results of blade thermal stress.

Testo completoAbstract (sommario):
A simulation program for transient analysis of the start-up procedure of heavy duty gas turbines for power generation has been constructed. Unsteady one-dimensional conservation equations are used and equation sets are solved numerically using a fully implicit method. A modified stage-stacking method has been adopted to estimate the operation of the compressor. Compressor stages are grouped into three categories (front, middle, rear), to which three different stage characteristic curves are applied in order to consider the different low-speed operating characteristics. Representative start-up sequences were adopted. The dynamic behavior of a representative heavy duty gas turbine was simulated for a full start-up procedure from zero to full speed. Simulated results matched the field data and confirmed unique characteristics such as the self-sustaining and the possibility of rear-stage choking at low speeds. Effects of the estimated schedules on the start-up characteristics were also investigated. Special attention was paid to the effects of modulating the variable inlet guide vane on start-up characteristics, which play a key role in the stable operation of gas turbines.

Testo completoAbstract (sommario):
The different turbulence models are adopted to simulate NASA-MarkII high pressure air-cooled gas turbine. The experimental work condition is Run 5411. The paper researches that the effect of different turbulence models for the flow and heat transfer characteristics of turbine. The turbulence models include: the laminar turbulence model, high Reynolds number k-ε turbulence model, low Reynolds number turbulence model (k-ω standard format, k-ω-SST and k-ω-SST-γ-θ) and B-L algebra turbulence model which is adopted by the compiled code. The results show that the different turbulence models can give good flow characteristics results of turbine, but the heat transfer characteristics results are different. Comparing to the experimental results, k-ω-SST-θ-γ turbulence model results are more accurate and can simulate accurately the flow and heat transfer characteristics of turbine with transition flow characteristics. But k-ω-SST-γ-θ turbulence model overestimates the turbulence kinetic energy of blade local region and makes the heat transfer coefficient higher. It causes that local region temperature is higher. The results of B-L algebra turbulence model show that the results of B-L model are accurate besides it has 4% temperature error in the transition region. As to the other turbulence models, the results show that all turbulence models can simulate the temperature distribution on the blade pressure surface except the laminar turbulence model underestimates the heat transfer coefficient of turbulence flow region. On the blade suction surface with transition flow characteristics, high Reynolds number k-ε turbulence model overestimates the heat transfer coefficient and causes the blade surface temperature is high about 90K than the experimental result. Low Reynolds number k-ω standard format and k-ω-SST turbulence models also overestimate the blade surface temperature value. So it can draw a conclusion that the unreasonable choice of turbulence models can cause biggish errors for conjugate heat transfer problem of turbine. The combination of k-ω-SST-γ-θ model and B-L algebra model can get more accurate turbine thermal environment results. In addition, in order to obtain the affect of different turbulence models for gas turbine conjugate heat transfer problem. The different turbulence models are adopted to simulate the different computation mesh domains (First case and Second case). As to each cooling passages, the first case gives the wall heat transfer coefficient of each cooling passages and the second case considers the conjugate heat transfer course between the cooling passages and blade. It can draw a conclusion that the application of heat transfer coefficient on the wall of each cooling passages avoids the accumulative error. So, for the turbine vane geometry models with complex cooling passages or holes, the choice of turbulence models and the analysis of different mesh domains are important. At last, different turbulence characteristic boundary conditions of turbine inner-cooling passages are given and K-ω-SST-γ-θ turbulence model is adopted in order to obtain the effect of turbulence characteristic boundary conditions for the conjugate heat transfer computation results. The results show that the turbulence characteristic boundary conditions of turbine inner-cooling passages have a great effect on the conjugate heat transfer results of high pressure gas turbine.

In this paper, the nonlinear vibration characteristics of the micro-beam structure acting by multi-couplings factors are investigated. Taking the nonlinear air damping force, alternating voltage excitation as well as the geometric nonlinearity of the micro-beam into account, the nonlinear vibration governing equations of the micro-beam are derived on the basis of the Euler-Bernoulli beam theory. The Galerkin method and harmonic balance method are adopted to obtain the amplitude-frequency response characteristic and phase-frequency response characteristic of the micro-beam structure. Then the effects of the nonlinear air damping force and the geometric nonlinearity on the resonance frequency and stiffness of micro-beam structure are analyzed.

Testo completoAbstract (sommario):
Regulating valves are the important components of control system on oil pipeline. The opening of the valves is changed to regulate flow and pressures of pipelines. Operating characteristic of valves is the most important factor influencing the regulating quality, and the distortion is great in actual operation with the variation of working conditions. Beginning with the inherent flow and resistance characteristics of regulating valves, the coefficient of discharge was adjusted considering the influence of fluid viscosity. The relationship between the deformity characteristics of valves and ratio of pressure cut down or turndown ratio was discussed. The system made up by a pump, a valve and a tank was an example to analyze the factors affected the operating characteristic of valves in the actual operation. The influences of different closing valve times, different closing valve laws and different ratio of pressure cut down or turndown ratio on the operating characteristic of valves were analyzed by simulation using Visual Basic program. The results indicated that the operating characteristics of valves were different. And the method of two-stage closing valve was adopted according to the changes of operating characteristic of valves by different closing valve time, different shutting valve laws. The distortion degree of valves in the operation of pipeline was decreased mostly. Then the selection measures of regulating valves were discussed. The factors influencing operating characteristic of valves were analyzed comprehensively. Theory criteria can be provided for selecting regulating valves of pipeline correctly. It is also the key to stable and economically operation control of pipelines.

Testo completoAbstract (sommario):
With a few exceptions, research on ride-hailing has focused on North American cities. Previous studies have identified the characteristics and preferences of ride-hailing adopters in a handful of cities. However, given their marked geographical focus, the relevance and applicability of such work to the practice of transport planning and regulation in cities in the Global South is minimal. In developing cities, the entrance of new transport services follows very different trajectories to those in North America and Europe, facing additional social, economic, and cultural challenges, and involving different strategies. Moreover, the determinants of mode choice might be mediated by social issues such as the perception of crime and the risk of sexual harassment in public transportation, which is often experienced by women in large cities such as Mexico. This paper examines ride-hailing in the Metropolitan Area of Mexico City, unpacking the characteristics of its users, the ways they differ from users of other transport modes, and the implications for urban mobility. Building on the household travel survey from 2017, our analytical approach is based on a set of categorical models. Findings suggest that gender, age, education, and being more mobile are determinants of ride-hailing adoption. The analysis shows that ride-hailing is used for occasional trips, and it is usually done for leisure and health trips as well as for night trips. The study also reflects on ride-hailings implications for the way women access the city.

Testo completoAbstract (sommario):
Multiple jurisdictions have adopted or adapted paid sick leave policies to reduce the likelihood of employees infected with SARS-CoV-2 presenting to work, which can lead to the spread of infection in workplaces. During the COVID-19 pandemic, paid sick leave has been associated with an increased likelihood of workers staying at home when symptomatic. Paid sick leave can support essential workers in following public health measures. This includes paid time off for essential workers when they are sick, have been exposed, need to self-isolate, need time off to get tested, when it is their turn to get vaccinated, and when their workplace closes due to an outbreak. In the United States, the introduction of a temporary paid sick leave, resulted in an estimated 50% reduction in the number of COVID-19 cases per state per day. The existing Canada Recovery Sickness Benefit (CRSB) cannot financially protect essential workers in following all public health measures, places the administrative burden of applying for the benefit on essential workers, and neither provides sufficient, nor timely payments. Table 1 lists the characteristics of a model paid sick leave program as compared with the CRSB. Implementation of the model program should be done in a way that is easy to navigate and quick for employers.

Testo completoAbstract (sommario):
In 2017, the State of California adopted landmark legislation to increase the funds available for transportation in the state: Senate Bill 1 (SB1), the Road Repair and Accountability Act of 2017. Through a combination of higher gas and diesel motor fuel taxes, SB1 raises revenue for four critical transportation needs in the state: road maintenance and rehabilitation, relief from congestion, improvements to trade corridors, and improving transit and rail services. To help state leaders identify the most important projects and programs to fund within those four topical areas, we conducted an online survey that asked a sample of 3,574 adult Californians their thoughts on how the state can achieve the SB1 objectives. The survey was administered from April to August 2019 with a survey platform and panel of respondents managed by Qualtrics. Quota sampling ensured that the final sample closely reflects California adults in terms of key socio-demographic characteristics and geographic distribution. Key findings included very strong support for improving all transportation modes, reducing air pollution and greenhouse gas emissions from transportation, and more convenient options to travel without driving. Respondents placed particular value on better maintenance for both local streets and roads, as well as highways. Finally, the majority of respondents assessed all types of transportation infrastructure in their communities as somewhat or very good.

Testo completoAbstract (sommario):
A fundamental responsibility of the National Park Service is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification. The mapping of stratigraphic units involves the evaluation of lithologies, bedding properties, thickness, geographic distribution, and other factors. If a new mappable geologic unit is identified, it may be described and named through a rigorously defined process that is standardized and codified by the professional geologic community (North American Commission on Stratigraphic Nomenclature 2005). In most instances when a new geologic unit such as a formation is described and named in the scientific literature, a specific and well-exposed section of the unit is designated as the type section or type locality (see Definitions). The type section is an important reference section for a named geologic unit which presents a relatively complete and representative profile for this unit. The type or reference section is important both historically and scientifically, and should be recorded such that other researchers may evaluate it in the future. Therefore, this inventory of geologic type sections in NPS areas is an important effort in documenting these locations in order that NPS staff recognize and protect these areas for future studies. The documentation of all geologic type sections throughout the 423 units of the NPS is an ambitious undertaking. The strategy for this project is to select a subset of parks to begin research for the occurrence of geologic type sections within particular parks. The focus adopted for completing the baseline inventories throughout the NPS was centered on the 32 inventory and monitoring networks (I&M) established during the late 1990s. The I&M networks are clusters of parks within a defined geographic area based on the ecoregions of North America (Fenneman 1946; Bailey 1976; Omernik 1987). These networks share similar physical resources (geology, hydrology, climate), biological resources (flora, fauna), and ecological characteristics. Specialists familiar with the resources and ecological parameters of the network, and associated parks, work with park staff to support network level activities (inventory, monitoring, research, data management). Adopting a network-based approach to inventories worked well when the NPS undertook paleontological resource inventories for the 32 I&M networks. The network approach is also being applied to the inventory for the geologic type sections in the NPS. The planning team from the NPS Geologic Resources Division who proposed and designed this inventory selected the Greater Yellowstone Inventory and Monitoring Network (GRYN) as the pilot network for initiating this project. Through the research undertaken to identify the geologic type sections within the parks of the GRYN, methodologies for data mining and reporting on these resources was established. Methodologies and reporting adopted for the GRYN have been used in the development of this type section inventory for the Chihuahuan Desert Inventory & Monitoring Network. The goal of this project is to consolidate information pertaining to geologic type sections which occur within NPS-administered areas, in order that this information is available throughout the NPS...

A fundamental responsibility of the National Park Service (NPS) is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification.

Pritchett, Lant, e Martina Viarengo. Learning Outcomes in Developing Countries: Four Hard Lessons from PISA-D. Research on Improving Systems of Education (RISE), aprile 2021. http://dx.doi.org/10.35489/bsg-rise-wp_2021/069.
Testo completoAbstract (sommario):
The learning crisis in developing countries is increasingly acknowledged (World Bank, 2018). The UN’s Sustainable Development Goals (SDG) include goals and targets for universal learning and the World Bank has adopted a goal of eliminating learning poverty. We use student level PISA-D results for seven countries (Cambodia, Ecuador, Guatemala, Honduras, Paraguay, Senegal, and Zambia) to examine inequality in learning outcomes at the global, country, and student level for public school students. We examine learning inequality using five dimensions of potential social disadvantage measured in PISA: sex, rurality, home language, immigrant status, and socio-economic status (SES)—using the PISA measure of ESCS (Economic, Social, and Cultural Status) to measure SES. We document four important facts. First, with the exception of Ecuador, less than a third of the advantaged (male, urban, native, home speakers of the language of instruction) and ESCS elite (plus 2 standard deviations above the mean) children enrolled in public schools in PISA-D countries reach the SDG minimal target of PISA level 2 or higher in mathematics (with similarly low levels for reading and science). Even if learning differentials of enrolled students along all five dimensions of disadvantage were eliminated, the vast majority of children in these countries would not reach the SDG minimum targets. Second, the inequality in learning outcomes of the in-school children who were assessed by the PISA by household ESCS is mostly smaller in these less developed countries than in OECD or high-performing non-OECD countries. If the PISA-D countries had the same relationship of learning to ESCS as Denmark (as an example of a typical OECD country) or Vietnam (a high-performing developing country) their enrolled ESCS disadvantaged children would do worse, not better, than they actually do. Third, the disadvantages in learning outcomes along four characteristics: sex, rurality, home language, and being an immigrant country are absolutely large, but still small compared to the enormous gap between the advantaged, ESCS average students, and the SDG minimums. Given the massive global inequalities, remediating within-country inequalities in learning, while undoubtedly important for equity and justice, leads to only modest gains towards the SDG targets. Fourth, even including both public and private school students, there are strikingly few children in PISA-D countries at high levels of performance. The absolute number of children at PISA level 4 or above (reached by roughly 30 percent of OECD children) in the low performing PISA-D countries is less than a few thousand individuals, sometimes only a few hundred—in some subjects and countries just double or single digits. These four hard lessons from PISA-D reinforce the need to address global equity by “raising the floor” and targeting low learning levels (Crouch and Rolleston, 2017; Crouch, Rolleston, and Gustafsson, 2020). As Vietnam and other recent successes show, this can be done in developing country settings if education systems align around learning to improve the effectiveness of the teaching and learning processes to improve early learning of foundational skills.
