In the Shadow of Schumpeter: W. Rupert Maclaurin and the Study of Technological Innovation     

Benoît Godin 《Minerva》2008,46(3):343-360

J. Schumpeter is a key figure, even a seminal one, on technological innovation. Most economists who study technological innovation refer to Schumpeter and his pioneering role in introducing innovation into economic studies. However, despite having brought forth the concept of innovation in economic theory, Schumpeter provided few if any analyses of the process of innovation itself. This paper suggests that the origin of systematic studies on technological innovation owes its existence to the economist W. Rupert Maclaurin from MIT. In the 1940s and 1950s, Maclaurin developed Schumpeter’s ideas, analyzing technological innovation as a process composed of several stages or steps, and proposed a theory of technological innovation, later called the linear model of innovation. The paper also argues that Maclaurin constructed one of the first taxonomies for measuring technological innovation.  相似文献

HIV/AIDS information needs of sexually transmitted infection clinic patients: content analysis of questions asked during prevention counseling     

Seth C. Kalichman  Demetria Cain  Joanna Knecht  Justin Hill 《Sex education》2013,13(1):11-23

Basic factual information about disease is the cornerstone of health promotion and disease prevention interventions. Previous studies have shown that content analysis of the questions asked of service providers can elucidate the information needs of service consumers. Questions asked by individuals at known high risk for HIV infection have not previously been examined. The current study analyzed 944 questions asked by 634 patients receiving HIV‐risk‐reduction counseling services at an urban sexually transmitted infections clinic. Questions were captured from audiotape recordings of risk‐reduction counseling sessions that were subsequently transcribed and content‐analyzed. A total of 49% of clients asked at least one question in their counseling session. Asking counselors questions was not associated with demographic characteristics or AIDS‐related knowledge. Questions were found to fit the AIDS information content structure identified in past research. The most common questions asked by sexually transmitted infection clients concerned condoms and other barrier methods of prevention (15%), HIV symptoms and disease progression (14%) and HIV antibody testing (11%). These results show that many individuals at high risk for HIV infection have substantial information needs, and that basic education about AIDS facts should not be neglected in HIV prevention interventions.  相似文献

Assessing the Relationship Between Perceived Message Sensation Value and Perceived Message Effectiveness: Analysis of PSAs From an Effective Campaign     

Seth M. Noar  Philip Palmgreen  Rick S. Zimmerman  Mia Liza A. Lustria  Hung-Yi Lu 《Communication Studies》2013,64(1):21-45

The current study is an analysis of public service announcements (PSAs) from an effective safer sex campaign that utilized a sensation-seeking targeting (SENTAR) approach. Two random samples of heterosexually active young adults (sample one N = 1,463, sample two N = 895) viewed different sets of safer sex PSAs on a laptop computer and answered questions about their perceived sensation value and perceived effectiveness. Multiple regression analyses examined the impact of (a) demographic, (b) individual difference, (c) sexual context, and (d) message variables including perceived message sensation value (PMSV) on the perceived message effectiveness (PME) of the PSAs. Results indicated that females, African Americans, condom users, and those with less education viewed the PSAs as slightly more effective than males, Caucasians, non-condom users, and those with more education. PMSV and personal utility emerged as the strongest predictors of PME, even after controlling for all of the aforementioned variables. Implications for further research on PMSV and perceived and actual effectiveness of PSAs are offered.  相似文献   

Association of Obesity with Hormonal Imbalance in Infertility: A Cross-Sectional Study in North Indian Women     

Bhavna Seth  Sarika Arora  Ritu Singh 《Indian journal of clinical biochemistry : IJCB》2013,28(4):342-347

Hormones play an important role in the development and regulation of reproductive function and the menstrual cycle of women. Extremes of body weight tend to affect the homeostasis of the hypothalamo–pituitary–gonadal axis. This cross-sectional study was carried out in 113 women (57 with primary infertility and 56 with secondary infertility) in the age group 20–35 years, presenting for hormonal evaluation of infertility in a tertiary care hospital. After preliminary clinical evaluation, anthropometric indices (height, weight, BMI, waist circumference and waist hip ratio) were measured in all subjects. Fasting blood sample drawn on second/third day of menstrual cycle was analysed for serum luteinizing hormone, follicle stimulating hormone (FSH), prolactin and thyroid stimulating hormone (TSH). Serum FSH levels showed a significant positive correlation with indicators of central obesity (waist circumference and waist hip ratio in both the study groups). In primary infertility, significant positive correlation was also observed between serum FSH levels and other markers of obesity like body weight, hip circumference and BMI. In secondary infertility, serum prolactin and serum TSH levels demonstrated a significant positive correlation with body weight and BMI. Obesity is associated with hormonal derangements which are responsible for infertility. In overweight women with infertility, weight loss should be considered as a first line treatment.  相似文献   

A Historical Comparison of the Social Origins of Broadcasting Policy, 1896–1920     

Seth Ashley 《Journal of Radio & Audio Media》2014,21(1):134-148

Using the United States and Great Britain as a comparative case study, this article employs a historical framework to consider the broad array of social, cultural, political, and economic contexts that led to divergent outcomes in the early development of broadcasting policy. This comparative historical analysis reveals the causal chains formed before the 1920s despite a period of post-war contingency. As a policy option, government control was removed in the United States but stayed in place in Britain after the war. This comparative approach can help to explain policy outcomes and inform modern policy debates.  相似文献   

Older-Learner Programs in Ohio: Policy and Practice Implications     

Seth Matthew Fishman 《Educational gerontology》2013,39(8):654-675

This conceptual paper contributes to the scholarship on life-long learning programs at public universities. It investigates the unique relationship between these institutions and their state, utilizing Ohio as an illustrative example. A review of several university mission statements illuminates the responsibility of these institutions to their older-learner programs. Particular emphasis is placed on Over-60 programs, a university course audit program found in many states. Older learners face many barriers and challenges on college campuses because institutions struggle with limited resources and support for older-learner programs. This paper further encourages dialogue about the benefits of older learner programs.  相似文献   

The Numbers Makers: Fifty Years of Science and Technology Official Statistics     

Godin  Benoit 《Minerva》2002,40(4):375-397

Official science and technology statistics arefifty years old. Among industrial countries,the forerunners were the United States, Canadaand Great Britain. This paper traces thedevelopment and the construction of S&Tstatistics in these three countries, and theirsubsequent standardization, mainly by theOECD, in the 1960s. It shows how military andscience policy needs drove the construction ofstatistics, until economic considerations cameto dominate their development. It alsodiscusses how statistics interacted withpolitics by way of studies that documentedgaps between OECD Member countries and betweenthe OECD and the USSR.  相似文献
