Although much digital divide research focuses on access to technology, another cause of the divide is the lack of information awareness that we call information asymmetry. Information asymmetry often stems from inadequate information sharing and can result in negative consequences for both the information poor and the information rich. Information asymmetry has been insufficiently studied as a possible cause of underdevelopment and inequality. In response, we develop a typology to classify information asymmetry into two categories, horizontal and vertical, and then identify those information sharing practices that cause the imbalance. To illustrate the negative consequences of information asymmetry and the potential benefits of information sharing, we discuss two examples from the experiences of modern American Indian tribes. First, Indian tribes face horizontal information asymmetry when they attempt to access the capital markets, and second, they face vertical information asymmetry in terms of law enforcement data sharing. This article also describes our ongoing examination of horizontal information sharing among tribes and vertical information sharing between tribes and others sovereigns in the American polity as possible solutions to the problems created by information asymmetry. These strategic responses are embodied in two information systems, the Tribal Financial Information Clearinghouse and an Intergovernmental Tracking System for sharing law enforcement data. We conclude with a discussion of how our typology can be more generally applied to other instances of information asymmetry. 相似文献

This paper explores the relationship between H. C. Ørsted’s research and teaching programme in order to uncover the way he attempted to sustain a dynamical approach to science through his lectures and textbooks. The main focus is the relation between Ørsted’s didactics as presented in his textbooks and other documents, his pedagogic activity, and his theoretical ideas in natural philosophy.1 The paper further provides evidence of how Ørsted’s students appropriated his dynamical system, epistemology, and pedagogy. 相似文献

Abstract To characterize hypertrophy and quantify seasonal changes in cardiac structure and function of women collegiate basketball (BB) athletes (n = 15), echocardiography (echo) measurements were made in the fall (FALL1), winter (WIN), and spring (SPR), then again during the subsequent fall (FALL2; n = 10). Comparisons were made to age-matched nonathletes (NA) measured during FALL1 (n = 22) and SPR (n = 5). Left ventricular (LV) internal dimension–diastole (LVIDd), LV end-diastolic volume (LVEDV), stroke volume (SV), LV mass (LVM), septal thickness (IVS), LV posterior wall thickness (LVPW), right ventricular (RV) internal dimension-diastole (RVIDd), and aortic root diameter (AOD) were significantly larger (12–70%) in the athletes; RVIDd-, LVEDV-, SV-, and LVM-index were also significantly greater (8–46%). From FALL1 to SPR measurement periods, LVWd, RVWd, LVEDV, SV, IVS, and LVM-index increased significantly (7–18%) in the athletes. Over the same period of time, LVIDd, LAD, AOD, LVEDV, and SV measured in the five NA subjects increased significantly. In the athletes, LVIDs, RVIDd, IVS, LVPW, and LVM decreased significantly (5–30%) from the SPR to FALL2 measurement period. These data characterize the general nature of the cardiac hypertrophy noted in women BB athletes compared to NA controls and show that distinct changes in heart structure corresponding to different periods of the competitive season can occur in these athletes. 相似文献

ABSTRACT
Background
The proportion of young people suffering from poor mental health is on the increase, including in Scandinavian countries. This increase seems paradoxical, as Scandinavian countries are among those with the lowest degree of material deprivation, economic inequality, and social exclusion. 相似文献6.

Part of the theory and all the experiments reported on in this paper were condensed into a four-page discussion or addendum to Professor Den Hartog's original paper on “Amplitudes of Non-Harmonic Vibrations” at the time of its presentation at the June Meeting of the A.S.M.E. in Chicago, 1933. Upon the instigation of Professor Den Hartog and the Editor of the Journal of the Franklin Institute, the original discussion has been brought into the present form. 相似文献

ABSTRACTThis study identify and reflect on barriers to inclusion that children with autism can meet in kindergarten. We use a single case study with participant- and video observation to map inclusion for a single 5-year-old boy with autism, in a mainstream kindergarten in Norway. Analysis identified three modes of inclusion; distance-keeping, maintaining proximity and interacting. The mapping procedure demonstrated that barriers to inclusion continue to operate. The extent of the child's participation seemed to relate to what he was doing and who he was with; overall, limited social inclusion amongst peers being achieved. Results indicated that predictable frameworks and teacher support increased participation. We discuss how participation for children with autism can be promoted. Our study points toward the need to extend current adaptations and support to children with autism within the educational settings, to enable a more inclusive practice. 相似文献
