從創新擴散的觀點探討企業在Inbound Marketing的導入 / Adopting inbound marketing:the perspective of innovation diffusion陳治平, Chen, Chih Ping Unknown Date (has links)
有關科技創新在擴散上的研究已行之有年,且有不少有關的研究發現及案例。但是創新的層面不只侷限於科技,在近年來服務創新、行銷創新等概念的興起,產生了創新領域內新的研究目標。而這些類型的創新擴散研究更是相當稀少,故本研究希望從此一方向進行探索性研究,期望同時有助於實務與學術的發展。
社會與科技的快速發展,促使網際網路的使用普及化,也影響到公司與消費者間的溝通及行銷模式。行銷創新:Inbound Marketing也是在這樣的情境下誕生。而近來台灣大量公司也採行Inbound Marketing作為重要的行銷手段時。讓公司不斷採納Inbound Marketing的理由及想法應該有可解釋的背後因素,所以本研究期望藉由研究的結果回答三點研究問題:(1) 影響行銷創新採用的重要關鍵因素為何?(2) 行銷創新擴散主要因素為何?(3) 不同產業在採用行銷創新上的異同為何?
本研究藉由文獻與學理的回顧,進一步探討Inbound Marketing行銷創新。以創新擴散、科技接受模式及兩階段理論作為基礎,發展出個案研究的基礎架構。研究架構將創新採用的過程,以創新決策流程作為基礎,區分為動機、啟發、執行及常規化等四個階段,並結合科技接受模式及兩階段理論中所討論的要素,進一步發展出構面。動機構面中含括創新、環境及組織等要素,啟發構面則包含設定標的及尋求創新等項目,執行構面則有重新定義及釐清兩個步驟,最後的構面則是常規化階段。本研究採用多重個案研究法,依前述的架構構面與變項進入深入的探討。
本研究所得到的初步結論包括:(1) 資源、環境及競爭要素是影響行銷創新採用的重要關鍵因素。(2) Inbound Marketing的高創新可近性是行銷創新擴散的主要因素。(3) 消費性電子及連鎖餐飲業在Inbound Marketing行銷創新採用的比較中,產業差異並不顯著。本論文最後進一步提出實務上及後續研究上的建議。 / Studies in innovation distribution and diffusion field have been researched for decades, but most innovation target will focus on technology innovation. Marketing innovation is still a new issue in innovation diffusion field. The study wants to be a base for following research in this topic.
Internet quickly developing has totally changed communication tools between customers and companies, and forced new marketing method (or “marketing innovation”) “Inbound Marketing” was generated. And in these years, more and more companies adopt inbound marketing as a regular marketing tool. This study tries to explain the factors and motivation of company adopts marketing innovations, main reason of marketing innovation diffusion and differences of marketing innovation adoption between different industries.
This study review innovation, marketing innovation related research, and make sure study target” Inbound Marketing” as a marketing innovation. And the study frame combines innovation diffusion, technology adoption model and two stage theory to analyze all study cases.
The study structure is divided into four stages: Motivation, Inspiration, Execution and Routinization. Motivation contains “Innovation”,” Environment” and “Organization” factors. Inspiration includes “setting targets” and “seeking innovation”. Execution has ” Re-define” and “clarify” two stages. Finally companies adopt innovation and “Routinization”.
The study finds “Resources”, “Environment” and “Competition” would be the main reason of marketing innovation adoption. And the high accessibility of inbound marketing with “Environment ” and “Competition” is the main factor of marketing innovation diffusion. Finally ,comparing “ Consumer Electronics Industry” and “ Chain restaurants” two industries, the difference in marketing innovation adoption is not obvious.

Faculty Perceptions about Virtual World Technology: Affordances and Barriers to AdoptionWood, Linda W 12 December 2010 (has links)
Providing instruction using different instructional delivery methods allows the learner to absorb content in a way that fits the individual learner. Today’s students have grown up immersed in digital technology. However, many higher education faculty are still not speaking the same digital language as their students. The issue may be that the pedagogical and epistemological beliefs of faculty who are “digital immigrants” affect the teaching methods used in the higher education classroom today. The purpose of this mixed methods study was to explore design college faculty perceptions of the adoption of virtual world technology into the classroom. Diffusion and adoption theories, adoption models, and patterns of adoption provided a conceptual framework for this study. This mixed methods study collected data through a survey and post-survey interviews administered to faculty of 21 design colleges. The quantitative survey instrument included questions about the usage of technology, including virtual world technology, in the higher education classroom. A total of 309 faculty completed the survey. Descriptive statistics, including frequencies, means, and standard deviations were used in the analysis. A correlation analysis was performed to determine if there was a relationship between selected variables and the survey responses. Post-survey semi-structured interviews were conducted with 12 faculty participants who volunteered for the interviews after participating in the survey. In this study, I used the constant comparative open coding hybrid method for the interview analysis. The specific research question posed in this study was: What are the perceptions of design college faculty regarding the use of virtual world technology in their courses? Guiding questions included: (a) What are faculty perceptions about virtual world technology that potentially affect its adoption into the classroom? (b) What are faculty perceptions of the affordances of using virtual world technology in the classroom? (c) What are faculty perceptions of the challenges of using virtual world technology in the classroom? In general, the results of this study indicate that while higher education faculty perceive that virtual world technology has the potential to be a useful teaching tool in the classroom, the faculty also perceive that they do not have the essential software and hardware support from their colleges to adopt this type of technology as a teaching tool in their courses.

Impact and Adoption of Proprietary Seed Technologies in Developing CountriesKathage, Jonas 04 February 2013 (has links)
In den 1980er Jahren begannen viele Entwicklungsländer, ihre Saatgutmärkte zu liberalisieren. In der Folge verbreitete sich die Nutzung proprietärer Saatguttechnologien, einschließlich gentechnisch veränderter Pflanzen (GV-Pflanzen). Die Konsequenzen dieser Entwicklung für Kleinbauern werden seither kontrovers diskutiert. Kritiker befürchten, dass Privatisierung die Qualität von Saatgut sowie den kleinbäuerlichen Zugang zu ihm verschlechtert. Befürworter gehen davon aus, dass proprietäres Saatgut landwirtschaftliche Produktivität und Einkommen steigern kann. In dieser Dissertation untersuchen wir Auswirkungen proprietärer Saatguttechnologien auf Kleinbauern. Bacillus thuringiensis-Baumwolle (Bt-Baumwolle) in Indien und Hybridmais in Tansania. Der dritte Fokus dieser Arbeit liegt auf der Adoption proprietärer Saatguttechnologien, wo erneut auf Hybridmais in Tansania Bezug genommen wird. Infolge einer ausländischen Investition transferierte eine indische Saatgutfirma Mitte der 1990er Jahre die Bt-Technologie in mehrere Baumwollhybriden. Diese Hybriden wurden 2002 zum Anbau zugelassen. In den Folgejahren verwendeten auch zahlreiche andere Saatgutfirmen die Bt-Technologie in ihren Züchtungsprogrammen. 2011 bauten 7 Millionen Bauern auf etwa 90% der indischen Baumwollfläche Bt-Baumwolle an. Sie ist gegen Kapselbohrer, eine Gruppe wichtiger Schädlingsinsekten, resistent. Dadurch kann sie den Einsatz von Insektiziden verringern und außerdem den effektiven Ertrag erhöhen. Dies würde Kosteneinsparungen bei Pestiziden und höhere Erlöse nach sich ziehen, welche wiederum das landwirtschaftliche Einkommen steigern können. Wenn aber die Saatgutpreise von Bt-Baumwolle hoch und die Ertragseffekte klein sind, könnte der Einkommenseffekt gering oder negativ ausfallen. Zu den Auswirkungen von Bt-Baumwolle wurden viele Studien publiziert, aber Selektionsverzerrungen, die Entwicklungsdynamik der Effekte und über Einzelfelder hinausgehende Wirkungen wurden bisher nicht ausreichend berücksichtigt. Hier analysieren wir Paneldaten aus dem Zeitraum 2002-2008. Mithilfe von Fixed-Effects-Modellen reduzieren wir Selektionsverzerrungen und betrachten den zeitlichen Verlauf der Effekte. Unsere Schätzergebnisse zeigen, dass Bt im Zeitraum 2002-2008 den Ertrag um 24% und den Deckungsbeitrag um 50% erhöhte, sowie den Lebensstandard im Zeitraum 2006-2008 um 18%. Außerdem finden wir Hinweise für eine Steigerung der Ertrag- und Deckungsbeitragseffekte über den gesamten Zeitraum. Einen Rückgang des Insektizideinsatzes in Bt- und konventionellen Feldern, der wahrscheinlich ein Zeichen für eine starke Dezimierung von Kapselbohrern durch die Zunahme des Bt-Anbaus ist, können wir ebenfalls beobachten. Nach der Liberalisierung des Saatgutmarkts in Tansania Anfang der 1990er Jahre begannen mehrere private Saatgutfirmen mit dem Vertrieb von Hybridmais. Hybriden können zu einem Ertragszuwachs führen, der wiederum Erlös und Einkommen steigern kann. Auf der anderen Seite könnte der Einkommenseffekt negativ ausfallen, wenn Hybridsaatgut teurer als Nichthybridsaatgut ist. Zudem kann ein leistungsstarker Nichthybride durchaus auch einen höheren Ertrag erzielen als mancher Hybride. Es gibt zwar Studien, die Produktivitätseffekte von Hybridmais in Afrika evaluieren, aber in der Regel kontrollieren sie nicht Störfaktoren, wie etwa Bodenqualität oder Düngereinsatz. Darüber hinaus liegen kaum Untersuchungen zu modernen Maissorten in Afrika vor, die neben der Produktivität auch Effekte auf den Lebensstandard landwirtschaftlicher Haushalte berücksichtigen. Wir analysieren einen Querschnittsdatensatz aus dem Norden und Osten des Landes und finden einen Ertragszuwachs von 50-60% durch Hybriden. Dieser führt auch zu einem höheren Deckungsbeitrag. Die Zugewinne treten vor allem im Norden auf, wo sie außerdem den Lebensstandard um 15% erhöhen. Im Osten bringen Hybriden keine Vorteile hinsichtlich Ertrag, Deckungsbeitrag oder Lebensstandard. Da sich jedoch die Mehrheit der Anwender im Norden befindet, profitieren in einer überregionalen Betrachtung die meisten Hybridnutzer von der Technologie. Außerdem finden wir heraus, dass der Ertragseffekt von Hybriden unabhängig vom Einsatz von Mineraldünger, Bewässerung, Pestiziden oder Mischanbau ist. Allerdings ist die Adoptionsrate von Hybridmais in Tansania gering. Ein möglicher Grund könnte darin liegen, dass seine Verwendung durch bestimmte Faktoren, wie etwa einen mangelnden Informationstand der Bauern bezüglich der Hybriden, erschwert ist. In unserer Stichprobe bauen 31% der Bauern Hybridmais an. Im Norden sind Hybriden den meisten Bauern bekannt und 49% verwenden die Technologie, während im Osten nur 50% von der Technologie gehört haben und nur 12% sie nutzen. Mithilfe des Average Treatment Effect Framework errechnen wir, dass eine Informierung aller Bauern über Hybriden die Adoptionsrate auf 45% ansteigen lassen würde. Jedoch wären dann die meisten neuen Anwender im Osten, wo die Ertrags- und Deckungsbeitragseffekte von Hybriden klein sind. Im Norden, wo die Adoption einträglicher ist, haben bereits fast alle Bauern von Hybriden gehört. Außerdem zeigt sich, dass eine Verbreitung von Informationen über Hybriden durch Beratung und ländliche Netzwerke im Norden (nicht im Osten) stattfindet und daher als Resultat der dort höheren Nützlichkeit verstanden werden kann. Für diese Interpretation spricht auch, dass wir keine Hinweise finden, dass Risiko oder Mangel an Kreditzugang die Adoption verhindern. Daher erscheint es wahrscheinlich, dass Informationsflüsse und Adoptionsentscheidungen primär vom Nutzen, den Hybriden gegenüber Nichthybriden bieten, bestimmt werden. Wir kommen zu dem Schluss, dass der Privatsektor verbesserte Saatguttechnologien für Kleinbauern in Entwicklungsländern liefern kann und dass derartige Saatguttechnologien einschließlich GV-Pflanzen diesen Kleinbauern dienlich sein können. Daher sollte die Liberalisierung von Saatgutmärkten in Entwicklungsländern unterstützt werden. Außerdem müssen Regulierungen, welche die Verfügbarkeit von Saatguttechnologien einschränken, den möglichen Nutzen dieser Technologien für Landwirte berücksichtigen. Und schließlich sollten Politik und Geberorganisationen in ihren Förderentscheidungen die Beseitigung von Adoptionshemmnissen gegen die Schaffung verbesserter Technologien abwägen.

Determining the Factors Contributing to Electronic Referral System Adoption by Radiation Oncologists through User-centred DesignChandran, Arun 21 November 2013 (has links)
This study aimed to utilize usability engineering methods in order to identify facilitators and barriers to
electronic referral system adoption by radiation oncologists at Princess Margaret Cancer Centre, and
provide recommendations for electronic referral system design. Analyses included workflow analysis of
radiation oncologists reviewing referrals, belief elicitation interviews with radiation oncologists, a
heuristic evaluation of an existing electronic referral system interface, and cognitive walkthrough of that
interface with radiation oncologists. Based on these findings, the system interface was redesigned using
mock-up software to address identified usability issues. The existing and redesigned interfaces were
compared using observational usability testing with radiation oncologists. The redesigned system
interface yielded reduced task times and enhanced user satisfaction as compared to the existing
interface. Thus, user-centred design was useful in determining facilitators and barriers to e-referral
adoption.

Αποτελεσματικότητα τεχνολογιών υγείας / Health technology efficiencyΠαπαθανασόπουλος, Φώτιος 05 July 2012 (has links)
Η παρούσα διατριβή έχει στόχο τη διερεύνηση της επίδρασης της νέας ιατρικής τεχνολογίας στην αποτελεσματικότητα παραγωγής των Μονάδων Εντατικής Θεραπείας (ΜΕΘ) στην Ελλάδα, καθώς και τον εντοπισμό των στοιχείων που επηρεάζουν τη διαδικασία λήψης αποφάσεων στο πλαίσιο του Εθνικού Συστήματος Υγείας (ΕΣΥ) για την υιοθέτηση ιατρικής τεχνολογίας.
Για την εκτίμηση της αποτελεσματικότητας κάθε μονάδας, εφαρμόζεται η τεχνική bootstrapped DEA των Simar και Wilson (2007), ενώ για την διερεύνηση των στοιχείων που οδηγούν στην απόφαση υιοθέτησης γίνεται χρήση υποδειγμάτων probit. Κατόπιν, με τη χρήση υποδειγμάτων επιβίωσης εντοπίζονται οι παράγοντες που κατηγοριοποιούν τις Νοσοκομειακές μονάδες αναφορικά με το χρόνο υιοθέτησης. Ο αξονικός τομογράφος στα δημόσια νοσοκομεία χρησιμοποιείται σαν μελέτη περίπτωσης.
Η μελέτη κατέδειξε ελλείμματα τόσο στην τεχνική αποτελεσματικότητα όσο και στην αποτελεσματικότητα κλίμακας στις περισσότερες μονάδες που εξετάστηκαν, κυρίως λόγω έλλειψης νοσηλευτικού προσωπικού. Τα αποτελέσματα δείχνουν ότι αν και η τεχνική αποτελεσματικότητα επωφελείται από την ενσωμάτωση των νέων ιατρικών τεχνολογιών, η αποτελεσματικότητα κλίμακας παραμένει ανεπηρέαστη. Αναφορικά με το την πιθανότητα και το χρόνο υιοθέτησης, διαπιστώθηκε ότι το μέγεθος του νοσοκομείου και η πληρότητα επιδρούν θετικά.
Τέλος, τα συμπεράσματα επεξηγούν το βαθμό στον οποίο η υιοθέτηση νέας τεχνολογίας επηρεάζει τόσο την αποτελεσματικότητα των Νοσοκομειακών μονάδων γενικότερα, όσο και τη διαδικασία λήψης σχετικών αποφάσεων.
Η παρούσα Διατριβή συμβάλλει στην γενικότερη ανάπτυξη της αποτελεσματικότητας του Συστήματος Υγείας και στην προώθηση του διαλόγου μεταξύ των εμπλεκόμενων στα θέματα διοίκησης και διαχείρισης του Συστήματος Υγείας. / This thesis aims to investigate the effect of new medical technology on the production efficiency of Intensive Care Units (ICUs) in Greece and unravel the elements which influence the decision making process concerning the adoption of new medical technologies in the context of the Greek Health System.
In order to evaluate the efficiency of each Unit, the bootstrapped DEA of Simar and Wilson (2007) is applied, while a probit model is used for exploring the elements that lead to the adoption decision. Then, the factors that categorize hospitals regarding the timing of adoption are identified through the use of survival models. Computerized tomography in the Greek public sector is used as a case study.
The study demonstrated deficits in both technical and scale efficiency in most Units, mainly due to lack of nursing staff. The results show that while technical efficiency has benefited from new medical technology integration, the scale efficiency remains unaffected. With respect to the likelihood and the time of adoption, it was found that the hospital’s size and plenitude have positive impact.
Finally, the findings explain the extent to which health technology adoption affects both the hospital’s efficiency and the decision-making process.
The present thesis contributes to the overall increase of the Health System efficiency as well as in promoting the dialogue between health administrators.

Previous issue date: 2015-04-01 / 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.

Previous issue date: 2015-04-28 / We estimate the effects of the adoption of mechanized agriculture led by a new environmental regulation on structural change of local labor markets within a large emerging country, Brazil. In 2002, the state of S\~{a}o Paulo passed a law outlying the timeline to end sugarcane pre-harvest burning in the state. The environmental law led to the fast adoption of mechanized harvest. We investigate if the labor intensity of sugarcane production decreases; and, if so, if it leads to structural changes in the labor market. We use satellite data containing the type of sugarcane harvesting -- manual or mechanic harvest -- paired with official labor market data.%, also geomorphometric data base for our instrumental variable correction. We find suggestive evidence that mechanization of the field led to an increase in utilization of formal workers and a reduction in formal labor intensity in the sugarcane sector. This is partially compensated by an increase in the share of workers in other agricultural crops and in the construction and services sector. Although we find a reduction in employment in the manufacturing sector, the demand generated by the new agro-industries affected positively the all sectors via an increase in workers' wage.

Previous issue date: 2013-02-26 / The increase number of food contamination cases, associated with increasing market competition, fostered the adoption and diffusion of new legal rules and certification systems related to food safety. Technical and sanitary barriers were created by import countries. The European Union has demanded traceability as a condition to have access to its market. These demand had impact on the national regulatory environment for food safety. In 2002, The Brazilian System of Identification and Certification of Bovine and Bubaline Origin (SISBOV) was created. The SISBOV certification is necessary, but not sufficient condition to export to EU market. The farm must also be part of TRACES (Trade Control and Expert System) certification. TRACES is a network created by EU for veterinary health which notifies, certifies and monitors trade in animals and animal products. However, the level of diffusion of this certification is low. A small number of farms have adopted and technological heterogeneity persists in bovine livestock production in Brazil. The aim of this thesis is to identify and analyze determinants of adoption of SISBOV and TRACES certification at the farm level in the State of São Paulo, Brazil. The literature on technology adoption and entrepreneurship provides a theoretical framework to understand how farmers behave with regard to an innovation. A survey questionnaire was used to get the information on farmer and farm characteristics. The logit model was used to analyze the cross section data from a sample of 32 certified farms and 52 non-certified counterfactual farms. The results suggest that the adoption of feedlot production system, associated to the adoption of hedge mechanisms, is an important determinant of the adoption of the certification. There is complementarity between the technologies. Also, the livestock and farm size, education, participation on farmer organization and being a member of a group of farmers informally organized, previous experience with other certification, business travels abroad and access to specialized information by web play a significant role in the adoption of both SISBOV and TRACES certification. / As ocorrências de casos de contaminações alimentares, associadas ao ambiente comercial competitivo, resultaram na difusão de exigências legais e sistemas de certificação relacionados à segurança do alimento. Barreiras técnicas e sanitárias foram criadas por países importadores. A União Europeia tem demandado a rastreabilidade para viabilizar o acesso ao seu mercado. Esta demanda teve impacto no ambiente regulatório da defesa agropecuária nacional. Em 2002, foi normatizado o Sistema Brasileiro de Identificação e Certificação de Origem Bovina e Bubalina (SISBOV). A certificação SISBOV é necessária, mas não é condição suficiente para exportar para o mercado europeu. A propriedade rural certificada pelo SISBOV deve fazer parte da lista TRACES (Trade Control and Expert System). TRACES é uma rede criada pela União Europeia para a saúde animal que notifica, certifica e monitora o comércio de animais e de produtos de origem animal. Entretanto, o nível de difusão desta certificação é baixo na pecuária de corte no Brasil. O objetivo dessa pesquisa é identificar e analisar os fatores que determinam a adoção da certificação SISBOV e TRACES no estado de São Paulo, Brasil. A literatura sobre adoção de tecnologia e empreendedorismo fornece a abordagem teórica para compreender o comportamento do pecuarista frente uma inovação. Um questionário estruturado foi utilizado para obter informações sobre características da propriedade rural, do sistema de produção e do pecuarista. O modelo logit foi utilizado para a análise dos dados transversais de uma amostra de 32 propriedades certificadas e 52 não certificadas. Os resultados sugerem que a adoção prévia de sistema intensivo de produção animal, que por sua vez é associado à utilização de instrumentos de gestão de risco, constitui um importante fator determinante da adoção da certificação SISBOV e TRACES. Este resultado deve-se à existência da complementaridade existente entre ambas as tecnologias. Ainda, o tamanho do rebanho e da propriedade rural, o nível de escolaridade, a participação do pecuarista em associação ligada à pecuária, o envolvimento em grupos não formais de pecuaristas, a experiência prévia com outras certificações, a prática de viagens a negócio ao exterior e o acesso à informação especializada por meio da web diferenciam as propriedades certificadas das não certificadas.
