Educational Reform in Russia and the USA: where are the troops?     

Hugh D. Hudson Jr  Alan J. Hoffman 《Educational studies》1993,19(3):255-265

To determine the level of support that differing concepts of educational reform had among the actual practitioners of public education in the former Soviet Union and the USA, a sample of teachers was surveyed to measure the value they placed on divergent educational goal statements as well as their respective philosophical orientations. This study found that US teachers were most committed to educational goals related to basic skills development and critical thinking and least supportive of goals related to creativity and enculturation; Russian teachers on the other hand were most supportive of interpersonal understanding and human relations, moral and ethical well‐being, and critical thinking, and least supportive of the goal related to citizenship and civic responsibility. With regard to educational philosophical orientation, US teachers were divided between maintaining order and stability, developing individual interests and abilities, and improving society. Russian teachers were more united in their belief that the purpose of education is to develop individual interests and abilities, with a significant minority selecting the ‘transforming society’ orientation.  相似文献   

MicroObservatory Net: A Network of Automated Remote Telescopes Dedicated to Educational Use

Many students have a deep interest in astronomy, but a limited opportunity to use telescopes to explore the heavens. The MicroObservatory Network of automated telescopes is designed to provide access to classroom teachers who wish their students to conduct projects over the World Wide Web. The intuitive interface makes it easy for even 10-year-olds to take pictures. Telescopes can be remotely pointed and focused: filters, field of view, and exposure times can be changed easily. Images are archived at the website, along with sample challenges and a user bulletin board, all of which encourage collaboration among schools. Wide geographic separation of instruments provides access to distant night skies during local daytime. Since first light in 1995, we have learned much about remote troubleshooting, designing for unattended use, and for acquiring the kinds of images that students desire. This network can be scaled up from its present capability of 240,000 images each year to provide telescope access for all US students with an interest in astronomy.

The Career Potential of Migrant Scholars: A Multiple Case Study of Long‐Term Academic Mobility in Finnish Universities     

David M. Hoffman 《Higher Education in Europe》2007,32(4):317-331

This multiple case study features interviews with forty‐two migrant scholars, from twenty‐seven countries, in five Finnish universities. In Finland, an aging, culturally homogeneous population is experiencing a rapidly transforming labour force and uncertainties about migration dynamics. This analysis illuminates a surprising degree of stratification, in a society normally associated with the absence of stratification. The framework presented in this study draws on higher education theory to highlight tensions between societal expectations of equity, in an age of global academic capitalism. The implications for stakeholders center on assessing higher education's capacity for explaining change within higher education, as well as society.  相似文献   

The rhythmic structure of mother-infant interaction in term and preterm infants   总被引：4，自引：0，他引：4  

B M Lester  J Hoffman  T B Brazelton 《Child development》1985,56(1):15-27

The purpose of this study was to quantify social interaction rhythms in 3- and 5-month-old term and preterm infants and their mothers. Infant-mother dyads were videotaped in a 3-min face-to-face paradigm. For each second of the interaction, separate scores were assigned to infant and mother indicating levels of affective involvement, creating 2 180-sec time series. Spectral and cross-spectral techniques were used to quantify periodicities in each member of the dyad and to estimate the synchrony or coherence of interactional rhythms between each infant and mother. Results showed the existence of periodicities in the behavior of each infant and mother at 3 and 5 months, with most subjects showing spectral peaks between .022 and .10 Hz. Increases from 3 to 5 months in behavioral periodicities were found for infants and mothers as well as for the coherence between infant-mother dyads. Term dyads showed higher coherence than preterm dyads at both 3 and 5 months. Term infants more often led the interaction at both ages. These results were taken as evidence that behavioral periodicities, which may be biologically based, underlie early mother-infant interaction and provide a temporal structure for the organization of cognitive and affective experience. Differences in synchrony between term and preterm infants may explain later reported differences in language between these groups.  相似文献   

Unwanted and illegal sexual experiences in childhood and adolescence     

Nancy D. KelloggThomas J. Hoffman 《Child abuse & neglect》1995,19(12)

Three hundred forty-two anonymous surveys regarding unwanted sexual experiences (USE) were filled out in three clinic sites: a pediatric sexual abuse clinic, family practice clinic, and family planning clinic. In the latter two clinics, 40% of females and 16% of males had at least one unwanted sexual experience prior to turning 18 years old. Only 91% of the sexual abuse clinic patients indicated their experience was unwanted. In addition, 27% of the subjects had wanted sexual experiences that were illegal and underreported: These experiences involved a partner at least 4 years older or younger. While feelings of victimization were most common, self-blame and naivete about the abuse were also frequently reported, especially in those who had an USE with a peer. Ambivalence, self-blame, and peer pressure were associated with a lower tendency to disclose one's USE. Although unwanted and illegal sexual experiences were less common in Hispanic females, feelings of self-blame and ambivalence regarding their USE were more frequent in comparison with White females. These findings have important investigative and therapeutic implications for professionals who encounter victims of sexual abuse.  相似文献   

A New Marketing Paradigm for Electronic Commerce   总被引：11，自引：0，他引：11  

Donna L. Hoffman Thomas  P. Novak 《The Information Society》1997,13(1):43-54

The World Wide Web possesses unique characteristics that distinguish it in important ways from traditional commercial communications environments. Because the Web presents a fundamentally different environment for marketing activities than traditional media, conventional marketing activities are becoming transformed, as they are often difficult to implement in their present form. In this article, we discuss the idea that these changes portend an evolution in the 'marketing concept' and argue that in order for marketing efforts to be successful in this new medium, a new business paradigm is required. In this new approach, the marketing function must be reconstructed to facilitate electronic commerce in the emerging electronic society underlying the Web.  相似文献   

How is radial arm maze behavior in rats related to locomotor search tactics?     

Cynthia M. Hoffman  William Timberlake  Joseph Leffel  Rory Gont 《Learning & behavior》1999,27(4):426-444

Norway rats have been shown to depend on short-term spatial memory to find food on a radial arm maze (RAM), but what locomotor search tactics are involved in using this memory effectively? Four experiments distinguished tactics of distance minimizing, central-place search, trail following, thigmotactic search, and random search by using different configurations of a RAM placed flat on the floor of an arena. These search tactics make similar predictions on an elevated RAM but predict different outcomes on a floor RAM because the rats are free to approach the food from any direction. After initial trials dominated by exploration, rats traveled along arms to food, even when the resultant distance was up to three times the minimum distance. With no food present, rats also traveled along arms; with no arms up to present, they traveled along walls to food. It appears that both maze arms and arena walls engage mechanisms related to trail following in rats.  相似文献   

In pursuit of the effective neighborhood information system: User-friendliness and training     

Sungsoo Hwang  Mark C. Hoffman 《Government Information Quarterly》2009

The goal of this research is to address the effectiveness of Neighborhood Information Systems (NIS) as an Information Technology (IT) tool in assisting community development. NISs are hybrid applications of Geographical Information Systems (GIS) and web technologies that provide demographic, social, and economic information to community stakeholders. Government agencies, nonprofit organizations, and community organizations engage in decision-making process for community development, and NISs are designed to help information-sharing and effective and participatory decision-makings for community development stakeholders.  相似文献   

Educational leadership and social activism: a call for action   总被引：1，自引：1，他引：0  

Lauren P. Hoffman 《Journal of educational administration and history》2009,41(4):391-410

The purpose of this article is to argue for a social activist stance in educational leadership that fundamentally addresses social change and human emancipation. This call for social activism is framed within neoliberal, neoconservative, and authoritarian populist discourses in the USA, which to social justice educators and leaders had devastating effects on education. Empirical data from an activist high school principal, activist university professor, and activist priest reflects their development of political clarity, political capacity, political collaboration, and an ethic of risk. It is suggested that the work of socially active educational leaders needs to be broadened to include such things as public policy advocacy, networking, organising, community development, and scholarship. Finally, the article concludes with a variety of ways educational leaders can demonstrate their social, moral, and political activism as they challenge the status quo, fight for social justice, and come to understand the politicised notion of leadership.  相似文献
