Barriers And Motivators

Nursery and greenhouse operations require significantly large amounts of water to maintain product quality and often use more than what is needed by the crop being grown. The nursery industry’s use of water is highly criticized and adds to arguments against agricultural water use with increasingly limited water resources available globally. The purpose of this study was to explore the barriers and motivators associated with nursery and greenhouse growers’ adoption of water conservation and treatment technologies. In-depth interviews were conducted with 24 operators across the U.S. to identify their perceptions of new water-saving technologies and treatments based on the five attributes of an innovation identified by Rogers (2003). The findings revealed growers are aware of water-saving technologies and the rate of adoption depends on a variety of factors including: perceived cost, lack of ability of their workforce to use the new technology due to its complexity, and belief that their product will be worth more if it is grown in an environmentally-friendly manner. Barriers to adoption included the high cost of replacing equipment, incompatibility with existing systems, and the perception that new technologies do not fit in with the traditional hands-on approach to horticulture. Suggested extension programs to reach growers include developing materials that highlight the economic benefit of adoption and cost recovery, YouTube videos that reduce issues with perceived complexity growers can use with their workers, and programs that emphasize how technology fits in with the culture of the horticulture industry.

Decision Making Model

There is an increasing necessity to implement water treatment technologies in order to optimize the use of freshwater resources as the global nursery and greenhouse industry grows. Unfortunately, their adoption has been limited. This study tested a conceptual model for technology adoption based on the Theory of Diffusion of Innovations in tandem with Adaption-Innovation Theory and Critical Thinking Style literature. Using a series of linear and logistic regressions, three characteristics of an innovation—relative advantage, complexity, and trialability—were identified as significant drivers of growers’ decisions to implement water treatment technologies. Growers who seek information when thinking critically and are more innovative when solving problems did not perceive new technologies to be compatible or to possess a relative advantage over their current systems. The results suggested most growers are unsure of how new technologies fit into their existing operations. Creating opportunities for growers to get hands on experience with new technologies, such as a field day, could assist in increasing growers’ implementation. In addition, developing a series of online videos highlighting how to use, adapt and troubleshoot the equipment would greatly enhance chances of long-term adoption.

The Impact

Abstract The rapid population growth has led to increasing demand for water resources. Studies have shown that the application of new technologies can effectively influence and promote citizens to save water. The application of smart water sensors can effectively monitor household water consumption and feedback the recorded data to citizens promptly, thereby influencing family members' water-saving attitudes and behaviours. For the widespread use of future water sensors in households, it can demonstrate its essential role in three aspects: water use information feedback to reduce water consumption, water information measurement helps to cultivate water conservation awareness, and water use information release as an effective means of behavioural intervention. This research provides some suggestions for the promotion and use of smart sensors in the home and points out the future research directions for the impact of water sensing on household water-saving behaviour.

Over 90 % of the farmers around Marsabit Mountain, a pocket of arable land amidst a predominantly arid area in northern Kenya, are former pastoralists, unfamiliar with productive and sustainable farming technologies. This paper describes how encouraging farmer innovativeness enhanced adoption and adaptation of water-saving technologies to suit individual farmers' needs. When farmers understood the principles behind a technology they were more likely to adapt it. Both men and women farmers were most interested in increasing their available income through improved technologies, but more women than men ranked labour saving as an important attribute of a new technology. More women adopted the new technologies, but men used them on a larger area than women. The paper also shows that agricultural productivity can substantially increase even if the theoretical full potential of the recommended practices might not be achieved. It is concluded that farmers need to be exposed to new ideas in exciting and thought provoking ways to tap their innovation potential.

Performance Computing

Recent events in the high-performance computing industry have concerned scientists and the general public regarding a crisis or a lack of leadership in the field. That concern is understandable considering the industry's history from 1993 to 1996. Cray Research, the historic leader in supercomputing technology, was unable to survive financially as an independent company and was acquired by Silicon Graphics. Two ambitious new companies that introduced new technologies in the late 1980s and early 1990s—Thinking Machines and Kendall Square Research—were commercial failures and went out of business. And Intel, which introduced its Paragon supercomputer in 1994, discontinued production only two years later.During the same time frame, scientists who had finished the laborious task of writing scientific codes to run on vector parallel supercomputers learned that those codes would have to be rewritten if they were to run on the next-generation, highly parallel architecture. Scientists who are not yet involved in high-performance computing are understandably hesitant about committing their time and energy to such an apparently unstable enterprise.However, beneath the commercial chaos of the last several years, a technological revolution has been occurring. The good news is that the revolution is over, leading to five to ten years of predictable stability, steady improvements in system performance, and increased productivity for scientific applications. It is time for scientists who were sitting on the fence to jump in and reap the benefits of the new technology.

This study aimed to examine the effects of regulatory focus and emotions on water-saving information dissemination. The findings revealed that when water-saving information is framed with a prevention focus, sad emotion fosters more active willingness to engage with the information dissemination than cheerful emotion. However, a promotion focus coupled with cheerfulness is slightly more persuasive than a promotion focus coupled with sadness. Furthermore, compared to the individuals in the nonfit group of emotions who had a regulatory focus, the individuals in the fit group formed a more favorable water-saving attitude and demonstrated a slightly higher willingness to disseminate water-saving information. This article is the first to contribute to exploring the dissemination of water-saving information from the perspective of the interactive effect of individual cognitive motivation and emotion.

Abstract In this essay, I offer a brief history of manuscript cataloguing and some observations on the innovations this practice introduced especially in the digital form. This history reveals that as the cataloguing of medieval manuscripts developed over time, so did the research needs it served. What was often considered traditional cataloguing practices had to be mediated to accommodate new scholarly advance, posing interesting questions, for example, on what new technologies can bring to this discussion. In the digital age, in particular, how do digital catalogues interact with their analogue counterparts? What skills and training are required of scholars interacting with this new technology? To this end, I will consider the importance of the digital environment to enable a more flexible approach to cataloguing. I will also discuss new insights into digital projects, especially the experience accrued by the The Production and Use of English Manuscripts 1060 to 1220 Project, and then propose that in the future cataloguing should be adaptable and shareable, and make full use of the different approaches to manuscripts generated by collaboration between scholars and librarians or the work of postgraduate students and early career researchers.

Hybrid Electric

Many leading companies in the automotive industry have been putting tremendous effort into developing new powertrains and technologies to make their products more energy efficient. Evaluating the fuel economy benefit of a new technology in specific powertrain systems is straightforward; and, in an early concept phase, obtaining a projection of energy efficiency benefits from new technologies is extremely useful. However, when carmakers consider new technology or powertrain configurations, they must deal with a trade-off problem involving factors such as energy efficiency and performance, because of the complexities of sizing a vehicle’s powertrain components, which directly affect its energy efficiency and dynamic performance. As powertrains of modern vehicles become more complicated, even more effort is required to design the size of each component. This study presents a component-sizing process based on the forward-looking vehicle simulator “Autonomie” and the optimization algorithm “POUNDERS”; the supervisory control strategy based on Pontryagin’s Minimum Principle (PMP) assures sufficient computational system efficiency. We tested the process by applying it to a single power-split hybrid electric vehicle to determine optimal values of gear ratios and each component size, where we defined the optimization problem as minimizing energy consumption when the vehicle’s dynamic performance is given as a performance constraint. The suggested sizing process will be helpful in determining optimal component sizes for vehicle powertrain to maximize fuel efficiency while dynamic performance is satisfied. Indeed, this process does not require the engineer’s intuition or rules based on heuristics required in the rule-based process.

Adoption Of New Technology

ABSTRACTDo world politics affect the adoption of new technology? States overwhelmingly rely on technology invented abroad, and their differential intensity of technology use accounts for many of their differences in economic development. Much of the literature on technology adoption focuses on domestic conditions. The authors argue instead that the structure of the international system is critical because it affects the level of competition among states, which in turn affects leaders’ willingness to enact policies that speed technology adoption. Countries adopt new technology as they seek to avoid being vulnerable to attack or coercion by other countries. By systematically examining states’ adoption of technology over the past two hundred years, the authors find that countries adopt new technologies faster when the international system is less concentrated, that changes in systemic concentration have a temporally causal effect on technology adoption, and that government policies to promote technology adoption are related to concerns about rising international competition. A competitive international system is an important incentive for technological change and may underlie global technology waves.

This article examines possible future developments with particular references to the role of new technology and the implications for Europe's agricultural producers. The main proposition is that the maintenance of commercial viability will oblige producers to adopt innovations and new practices, but the most successful will be farmers with the greater economic resources and superior managerial abilities. The outcome will be increasing socio-economic differentiation within the EEC population of agricultural producers and an increasing proportion of farm output coming from the top 20 per cent of farmers in the Community.

Consumers pay for hundreds of goods and services each year, but across households and across goods, consumers do not choose to pay the same way. This paper posits that payment choices depend in part on consumers' propensity to adopt new technologies and in part on the nature of the transaction. To test this hypothesis, this paper analyzes consumer's payment instrument use at the point of sale and for bill payment. The sample includes consumers surveyed in 2001, who are primarily users of the Internet. The results indicate that consumers who use new technology or computers are more likely to use electronic forms of payment, such as debit cards and electronic bill payments. Particularly, the use of direct deposit is a significant predictor of electronic payment use. Furthermore, the results indicate that payment choice depends on the characteristics of the transaction, such as the transaction value, the physical characteristics of the point of sale, and a bill's frequency and value variability.
