Institutional Sources of Variation in Embedded Agency : The Adoption of Unconventional Therapies by Conventional Hospitals

Who initiates change? Prior research has generally focused on an organization’s position in a field as a proxy for institutional embeddedness that influences organizational decisions to change. For instance, central organizations deeply embedded in institutional environment are less likely to innovate. In contrast, we argue that institutional influence assumed to exist in the position varies according to sources that condition the degree of embeddedness. As for the sources, we concentrate on the heterogeneity and intensity of associations that an organization has with other actors and parties in the environment. We examine our arguments in a study of the formal incorporation of unconventional medicine into conventional hospitals. Unconventional medicine includes a group of treatment therapies (e.g., acupuncture, therapeutic touch, naturopathy, etc.) whose underlying principles rest uneasily with those of dominant conventional medicine. Analyzing a dataset of 245 hospitals from 1992 to 2001, we find that the hospitals with greater degree of heterogeneity in embeddedness are more likely to adopt unconventional therapies. The adoption of unconventional therapies is high at the middle and low at both the top and bottom of embeddedness intensity. Implications for the study of how the embeddedness of agency arises are discussed.

Recently, the regulation of CO₂ emission from vehicles is more and more strengthened for the prevention of global warming and energy conservation. Therefore, the demand for the low fuel consuming power train is steadily increasing. Among many solutions, HSDI(High Speed Direct Injection) diesel engine is suggested for reducing the emission level of CO₂. Also, HSDI diesel engine is evaluated as one of most substantial solution because of its inherent good fuel economy. This study was carried out to investigate the characteristics of the in-cylinder swirl flow generated by a 4-valve cylinder head of small size with a tangential and a helical intake port. The calculations of the in-cylinder velocity field have been conducted by CFD code and the flow coefficient(C<SUB>f</SUB>), swirl ratio(Rs), mass flow rate(m<SUB>s</SUB>) were measured in the steady flow test rig using ISM(impulse swirl meter). As the results from steady flow test, mass flow rate of a head for short distance between each independent port is increased about 13% than the another. But non-dimensional swirl ratio is decreased about 15%. From flow fields image acquired by laser sheet method and calculation, we found that the center position of swirl was eccentric.

While prior work has noted the importance of knowledge creation in gaining competitive advantages, much less is understood about why firms do not actually use what they create. Building upon institutional approaches to organization studies, we offer a new framework to explain the gap between knowledge creation and utilization. We test our framework in an empirical context of sustainable innovation and environmental technologies where ideas of environmental sustainability have recently gained public popularity and shaped how interested audiences make evaluative assessments of firms. In such a context, firms are apt to perceive the social attention toward sustainability to be a normative pressure, which causes them to create new knowledge and develop technologies consistent with the social attention. Using data from the government-initiated certification system for green technologies, our study finds that firms do not always fully implement new environmental technologies they develop in response to the certification program, the situation we refer to as knowledge decoupling. We also examine a set of conditions under which knowledge decoupling becomes more or less amplified. Taken together, our findings show how a firm`s knowledge creation and utilization may be shaped by its external institutional environment as well as internal learning processes.

혁신지향 시장창출 및 기업가정신에 대한 제도론적 접근 : 신규 시장범주에서 이해관계자 집단의 정치적 역동을 중심으로

본 연구는 거시조직이론의 관점에서 신규 시장범주의 출현과 성장에 영향을 미치는 제도적 기반의 역할을 탐색한다. 혁신지향 창업에 관한 거시조직이론 분야의 기존 연구들은 대체로 창의적인 사업가의 사업기회 포착과 경제적 가치 제고를 촉진하는 시장 환경적 요인에 초점을 맞춘다. 특히 신제도주의 관점에 따른 조직이론 연구는 기업가들이 창업과정에서 겪는 불확실성이 신규 시장범주의 출현과 성장에 중대한 장애로 작동하므로, 그러한 불확실성을 해소하는 방향으로 제도적 기반이 설계될 필요성을 지적한다. 이러한 기존 연구흐름과 달리 본 연구는 혁신지향 시장창출을 촉진하기 위한 제도가 불확실성을 낮춰야 한다는 당위적 주장이 항상 작동하지 않는 현실적 괴리가 있음을 강조한다. 이러한 괴리를 체계적으로 설명할 수 있는 이론적 논의를 제시하기 위해서, 본 연구는 첫째, 신규 시장범주의 등장과 성장에 필요한 물적 자원의 본질적 속성 분석이 중요함을 강조한다. 둘째, 해당 자원의 사용을 두고 기존 및 신규시장 참여자들이 맺는 이해관계의 충돌과 이에서 비롯되는 정치적 영향력의 상대적 차이를 분석한다. 셋째, 해당 자원의 의미를 규정하고 그 자원의 활용을 규제하는 제도적 기반이 구성되는 과정과 결과를 분석한다. 이에 기반하여 본 연구는 신규 시장범주의 작동에 필수적인 자원을 공식적으로 정의하고 인식하는 법-제도적 체계가 이해관계자들의 정치적 역동과 여러 맥락적 요인에 따라 상당히 달라지며, 이는 창업 등 기업가정신의 발현을 통한 신규 시장범주의 출현과 성장에 영향을 미친다고 주장한다. 이 주장의 이론적 근거는 법사회학, 제도주의 조직이론, 사회운동이론에서 도출하며, 이론적 타당성과 실증분석 가능성 검토를 위해 신재생에너지(지열발전) 시장범주를 탐색적 예시로 제시한다. 본 연구는 신제도주의 조직이론과 혁신시장 창출 및 기업가정신 연구에 기여하고, 기업전략 및 시장정책 수립과 평가에 실천적 시사점을 제공한다. This study builds upon neo-institutional perspectives to explore the constitutive role of laws and regulations in affecting the legitimation of new market categories. Although institutions are regarded as an important means to address the uncertainty inherent in new markets, little is known about the institutional sources of such uncertainty—a serious omission that prevents scholars from developing a nuanced theory of institutions and entrepreneurship. This study proposes that it can be useful to view innovation-oriented market creation as a sociopolitical process in which a number of stakeholders with varying interests in the use of scarce resources critical to entrepreneurial activities proactively intervene with regard to how the resources are formally classified and subjected to relevant laws and regulations. This process often invites political contestations between incumbents who wish to maintain the status quo of established markets and challengers who strive to create new opportunities in the market category. Depending on the relative influence of these two groups of stakeholders, the aforementioned process will result in a differing level of institutional uncertainty that constrains the legitimation of new market categories and its consequential impact on entrepreneurship. The study offers a set of theoretical propositions and explores the validity of its theoretical framework using an illustrative case of renewable energy production.

A contingent approach to energy mix policy

Kim, Jiwon,Park, Sangchan Elsevier 2018 Energy Policy Vol.123 No.-

<P><B>Abstract</B></P> <P>Prior work has suggested that cultivating environmentally friendly energy sources can strike a balance between reducing CO<SUB>2</SUB> emissions and fostering economic growth, yet little is known about whether and how energy-mix policies tap into the balance. Energy-mix is important mainly because maintaining energy supplies exclusively using renewable energy sources is not completely feasible. Our study takes a contingent approach to energy mix policies and suggests that the appropriate mix for reducing carbon emissions is not static but dynamic depending on the developmental stages of national economic systems. We follow the Environmental Kuznets Curve (EKC) hypothesis, the most influential model for relating CO<SUB>2</SUB> emissions to economic development, but depart from it by utilizing multifactor productivity data, rather than the conventional measure of GDP per capita, to capture economic growth. Empirical analyses of OECD countries from 1985 to 2013 show that the best energy policies for OECD countries is the gradual decrease in their relative reliance on natural gas, nuclear power, bio and waste fuels in a short run, over the next about 9, 2 and 5 years respectively, whereas solar and wind power can decrease CO<SUB>2</SUB> in a long run as the economy continues to grow.</P> <P><B>Highlights</B></P> <P> <UL> <LI> An appropriate energy mix for reducing carbon emissions is not static but dynamic. </LI> <LI> Developmental stages of national economy condition the proper energy mix. </LI> <LI> MFP is a good alternative to GDP to capture economic developments. </LI> <LI> Solar and wind power can reduce CO<SUB>2</SUB> emissions even if the economy is mature. </LI> <LI> Natural gas, bio & waste fuels, and nuclear power reduce CO<SUB>2</SUB> in the short run only. </LI> </UL> </P>
