Master Gardener training was delivered via interactive television (IT) or face-to-face (FTF) in 1996 and 1997. Following 1997 training, instructors were surveyed to determine if the method of program delivery influenced their perceptions of Master Gardener training. Most instructors preferred FTF program delivery as compared to IT training. More preparation time was spent in developing lecture notes, text slides, and visual aids for IT vs. FTF training. Although instructors were more comfortable with FTF training than IT programming, their comfort level with IT training increased with experience. A major reason for instructor discomfort with IT was the lack of personal contact with trainees. Although lack of interactivity was identified as a limiting factor with IT training, trainees monopolizing time during sessions was a major constraint for FTF training. In spite of instructor preference for FTF Master Gardener training, nearly all instructors indicated a willingness to teach IT training again. Motivating factors for future IT training included less night time instruction, less need to travel, job efficiency, and the opportunity to use new technology.

Master Gardener training was delivered via interactive television (IT) or face to face (FTF) in Missouri in 1997. IT and FTF participants were surveyed on their acceptance of the Master Gardener training method and their perceptions of program quality and technology to evaluate the newly developed multiple site IT training. Demographic characteristics were also recorded to determine if IT format attracted a different clientele than that of FTF training. Those who participated in IT training generally had more years of education than those in the FTF training and lived in suburban rather than rural areas. IT participants missed fewer training sessions than FTF participants. However, IT participants rated the slide quality, sound, and overall training lower than the FTF group. Some problems associated with IT training identified by the participants are correctable, which should improve future acceptance of this technology.

Purpose Consistent with the dynamic capabilities view tenets, this paper aims to conceptualize a theoretical framework of service innovation in the hotel industry. Design/methodology/approach This study uses a qualitative method with a content analysis approach. The data were collected using a snowball sampling method and semi-structured interviews with 14 experts in Tehran's hotel industry. Findings The findings demonstrate that the most significant factors are using the new technology, keeping up with it, training human labor, being up-to-date and adopting new infrastructures. Results also reveal that improper management and lack of knowledge are the most critical factors behind service innovation failure in the hotel industry. Regarding the infrastructures needed to develop service innovation in the hotel industry, the results show that adopting the newest technology in diverse aspects, human infrastructure, the capital and appropriate space and place are the key factors. Originality/value This paper contributes to the literature by linking the service innovation perspective to the dynamic capabilities view. It explains how hotels can enhance service innovation to gain a competitive advantage. Therefore, both academicians and hoteliers can develop action plans by selecting and managing the service innovation process.

This article presents a review on the use of graphene in various segments, elucidating that this product can be used in various industrial sectors. These include mainly agriculture (as in large crops of high relevance, such as coffee), the food industry and the environment, as a plant growth stimulator and in fertilizers, nanoencapsulation and smart-release systems, antifungal and antibacterial agents, smart packaging, water treatment and ultrafiltration, contaminant removal, pesticide and insecticide quantitation, detection systems and precision agriculture. However, some challenges can be overcome before the graphene-based nanoparticle is used on a large scale. In this way, before using the product in the environment, it is necessary to determine whether the technology is safe for the soil-plant system and consumers. Furthermore, the cost of its use can also be a limiting factor depending on the level applied. Therefore, this review proposes to examine the diverse literature to explain the effects of the use of graphene in agriculture, plants and soil microorganisms. Accordingly, this article discusses and presents the possibilities of application of graphene in agriculture, plants and soil microorganisms.

ABSTRACTBackgroundStalk lodging (breakage of plant stems prior to harvest) is a major problem for both farmers and plant breeders. A limiting factor in addressing this problem is the lack of a reliable method for phenotyping stalk strength. Previous methods of phenotyping stalk strength induce failure patterns different from those observed in natural lodging events. This paper describes a new device for field-based phenotyping of stalk strength called “DARLING” (Device for Assessing Resistance to Lodging IN Grains). The DARLING apparatus consists of a vertical arm which is connected to a horizontal footplate by a hinge. The operator places the device next to a stalk, aligns the stalk with a force sensor, steps on the footplate, and then pushes the vertical arm forward until the stalk breaks. Force and rotation are continuously recorded during the test and these quantities are used to calculate two quantities: stalk flexural stiffness and stalk bending strength.ResultsField testing of DARLING was performed at multiple sites. Validation was based upon three factors. First, the device induces the characteristic “crease” or Brazier buckling failure patterns observed in naturally lodged stalks. Second, in agreement with prior research, flexural stiffness values attained using the DARLING apparatus are strongly correlated with bending strength measurements. Finally, a paired specimen experimental design was used to determine that the flexural data obtained with DARLING is in agreement with laboratory-based flexural testing results of the same specimens. DARLING was also deployed in the field to assess phenotyping throughput (# of stalks phenotyped per hour). Over approximately 5000 tests, the average testing rate was found to be 210 stalks/hour.ConclusionsThe DARLING apparatus provides a quantitative assessment of stalk strength in a field setting. It induces the same failure patterns observed in natural lodging events. DARLING can also be used to perform non-destructive flexural tests. This new technology has many applications, including breeding, genetic studies on stalk strength, longitudinal studies of stalk flexural stiffness, and risk assessment of lodging propensity.

Master Gardener programs were conducted through 10 of Maine's 16 county offices in 1993. In an effort to reduce the number of identical presentations given by the limited number of instructors, 5 of the 10 sessions were conducted via interactive television (ITV), while the remaining 5 sessions were held locally. Participants (n=215) were surveyed about their learning experience in fall 1993. Data compare the local ITV audience vs. 7 distant audiences viewing sessions in real time vs. 2 audiences viewing taped sessions at a later date, on test scores of material presented, and on attitudes about the program. Data also summarize the types of projects on which Master Gardener volunteer hours were applied, and participants' attitudes about how volunteer programs could be made more effective.

The text is born of a rhetorical question: If we could make a pact with the Devil, what kind of interactive television would we stipulate?The answer requires us to reflect above all on the value we give ITV as a new technology, and it warns us about the risks of using the simple model of means and goals.If we ask a new gadget what problem it solves, we might get an answer biased by a certain amount of technological determinism that would distort the role that the device plays in its social surroundings and could impede our seeing what we would really be mortgaging our souls for. El texto parte de una pregunta retórica: qué televisión interactiva ideal pactaríamos con el Diablo, si ello fuera posible. La respuesta recomienda evitar la precipitación y reflexionar sobre el papel que la nueva tecnología jugará en el entorno en que se inscriba. Señala la pertinencia de establecer una estructura conceptual desde la cual determinar el carácter innovador de las nuevas tecnologías que tenga en cuenta la complejidad de tal objetivo, advirtiendo sobre los riesgos de usar el sencillo modelo de medios y fines (problema-solución). Preguntándole a la televisión interactiva qué problema resuelve se corre el riesgo de obtener una respuesta sesgada por cierto grado de determinismo tecnológico que distorsione el papel que los nuevos dispositivos juegan en el entorno social en que se inscriben. Se analizan tres cuestiones clave. Primero, el problema que la nueva tecnología soluciona no existe antes del nuevo dispositivo; el problema se identifica como tal porque ya existe la innovación y se dispone de información sobre ella. Segundo, las consecuencias de una innovación tecnológica son complejas (no se limitan a aportar soluciones a lo que percibimos como problemático). Pueden empezar siendo un medio para un fin antiguo, pero su puesta a punto puede acabar alterando el valor de lo problemático. Y tercero, la tecnología no puede ser caracterizada como un medio para un fin. Esto es así por varias razones: es un error pensar que la utilidad es valiosa en sí misma, la frontera entre medios y fines no es tan evidente como podría parecer, y la evaluación de lo nuevo debe contemplar tanto el criterio de utilidad como el de valor. Tener en cuenta estas cuestiones permitiría valorar la televisión interactiva desde un marco conceptual que interprete la relación entre la técnica y lo social como una red de influencias mutuas e interdependientes y proporcione algunas pistas que permitan prever a cambio de qué se hipotecaría el alma, realmente.

Interest in the educational satellite technology in Cooperative Extension is increasing rapidly. This study describes program delivery through the Cornell Cooperative Extension Satellite Network (CCESN) as a new educational initiative in the information age. The description is focused on examining extension educators' perspectives on teaching techniques, communication channels, and factors related to participation in the program. The study found that traditional educational techniques such as multiple speakers, interviewing, case studies, team teaching, and panel discussions were seen as only somewhat effective, and communication channels such as face-to-face contact, small group meetings, interactions with local county extension staff, and personal contact by telephone more effective than satellites and computers. Factors encouraging participation include economy of scale, access to information and other resources, professionalization of programming, and interactivity, and those that discouraged participation include lack of interactivity, programming costs, lack of depth in content, and technical support. Further study is needed to probe satellite technology as a single educational delivery or one needing combination with other technologies.

Interactive multimedia and the so-called information highway, and its exemplar the Internet, are enabling a new economy based on the networking of human intelligence. In the digital frontier of this economy, the players, dynamics, rules, and requirements for survival and success are all changing. The difficulties in sustaining the business models, which have been recently created worldwide, makes this topic extremely relevant in order to understand the sustainability of competitive advantage in the television environment. How will the market for digital interactive television develop? We are going to be consuming more communication, both broadcast and narrowcast, and at least for the immediate future this communication will take digital forms. Costs and prices are falling because of technological progress in processing and transmission, and because of increased supplies of spectrum from the government, not merely for economies of scale in sharing pipelines. Conventional television seems to satisfy a demand for which interactive television is not a very good substitute. Many studies in the economic literature of leisure time use (Robinson & Goeffrey Godbey, 1997) shed light on the demand issue, and they affirm that part of the allure of television is freedom of choice and interactive television may actually be less appealing to people if they must invest more energy and imagination. Managers must not forget that the final player of the iTV value chain is obviously the end user, whose behaviour and preferences are critical factors determining the success of the other players and of the whole industry. Future demand and penetration of interactive TV is expected to grow very fast. Forecasts assert that Europe’s iTV penetration will reach 44% of European households by 2007, up from only 11% in 2002,1 with four countries (UK, France, Spain, and Italy) driving the growth and accounting for 70% of Europe’s iTV households. When considering these projections it is useful to remember the “crossing the chasm”2 paradigm in the technology-adoption lifecycle model. Crossing the chasm is jumping that empty area between the innovators’ segment and the early majority. The early adopters are iTV enthusiasts and are always looking forward to experience technology innovations. Being the first, they are also prepared to bear with the inevitable bugs that accompany any innovation just coming to market. By contrast, the early majority is looking to minimise the discontinuity with the old ways, and they do not want to debug somebody else’s product. By the time they adopt it, they want it to work properly and to integrate appropriately with their existing technology base. Visionary early adopters and the pragmatist early majority have completely different frames of mind about technology; because of these incompatibilities, early adopter surveys don’t help to really understand and to predict accurately how consumer behaviour might change as a response to the introduction of the new technology.

This case study highlights the concept that the “management” of the technology is usually the limiting factor causing the demise of a project rather than the “technology” itself. This real case study involves creating an awareness of a new technology within the company and trying to start a much-needed project using this technology

Autologous skin grafts (autografts) remain the gold standard in the treatment of skin loss. For extensive wounds or burns, however, identifying adequate donor sites can be the limiting factor. Additionally, donor sites are associated with pain, risk of infection, and poor cosmetic outcomes. Many skin substitutes have been engineered as alternatives to traditional autografts. These substitutes, however, all leave something to be desired either functionally or cosmetically. This report describes the use of a new technology, autologous homologous skin constructs, to regenerate full-thickness skin grafts that maintain functional polarity, allowing important components of skin such as glands and hair follicles to regenerate. These grafts only require small samples of full-thickness skin from the patient, decreasing issues of donor site availability.
