Bringing the Social Back into Economies: Progress or Reductionism?.

Section 2 of this paper suggests that economics has long sought to colonise other social sciences. It has, however, only achived limites success because of its alien methods and its need to take the social as given. Section 3 argues that there is now a newer version of economic imperialism drawing upon the new microfoundation principles associated with information imperfections. In view of rational response to market imperfections, these purport to be able to explain the social whether the latter be non-economic or collective forms of behaviour. Section 4 presents illustrations of the way in which imperialism is bringing the social back into its analysis, drawing in broad brush rather than detail upon the new economic sociology, the new institutional economics, the new economic history, the new development economics, and the all-embracing notion of social capital.SOCIETY ; SOCIALISM ; ECONOMIC THEORY

Equilibrium entanglement vanishes at finite temperature

We show that the equilibrium entanglement of a bipartite system having a finite number of quantum states vanishes at finite temperature, for arbitrary interactions between its constituents and with the environment.Comment: 2 pages, no figures, first submitted on July 22, 200

Kinetic Parameters for the Hydrogen and Ethylene Flames from Flashback Measurements

Values for the flame activation energy and an overall reaction order have been obtained for premixed hydrogen-oxygen and ethylene-oxygen flames with nitrogen and with argon as diluents; the values come from measurements of the change with pressure and flame temperature of the critical boundary velocity gradient for flashback. Measurements have been made for rich and stoichiometric hydrogen flames and for lean and stoichiometric ethylene flames. For hydrogen flames with nitrogen diluent an overall order of 2*3 is found; for ethylene flames with nitrogen diluent, the order obtained is 1*8. With argon diluent, values for the order are about 10 per cent lower for each flame. With nitrogen diluent the flame activation energy apparently increases with flame temperature; this increase is not found with argon diluent. For hydrocarbon flames the assumption that the initial equivalence ratio equals the effective equivalence ratio in the flame leads to an order of reaction with respect to oxygen that is considerably larger than unity. For hydrogen flames, that assumption is consistent with an oxygen order of unity

Dimensionality of spin modulations in 1/8-doped lanthanum cuprates from the perspective of NQR and muSR experiments

We investigate the dimensionality of inhomogeneous spin modulation patterns in the cuprate family of high-temperature superconductors with particular focus on 1/8-doped lanthanum cuprates. We compare one-dimensional stripe modulation pattern with two-dimensional checkerboard of spin vortices in the context of nuclear quadrupole resonance(NQR) and muon spin rotation(muSR) experiments. In addition, we also consider the third pattern, a two-dimensional superposition of spin spirals. Overall, we have found that none of the above patterns leads to a consistent interpretation of the two types of experiments considered. This, in particular, implies that the spin vortex checkerboard cannot be ruled out on the basis of available NQR/muSR experimental results.Comment: 6 pages, 2 figure

Are QR codes here to stay or are they a thing of the past?

Quick response (QR) codes, a type of two-dimensional barcode, are a marketing tool used all around the world. Particularly, in Japan and China QR codes have been gaining popularity. Early adopters with higher education and recent promotional marketing campaigns are utilizing this mobile, information-sharing tool. QR codes are now widely used as a marketing tool by many companies. This research investigates consumers’ perception of QR codes. An increasing amount of firms and sales representatives are using QR codes as a channel to market their products/services to their customers’ mobile devices. The following questions will be the focus of this study: 1. What are the factors that impact consumers’ attitudes towards QR codes? 2. Does the location of the code have an effect on the attitude towards the QR code? 3. Do consumers have a more positive attitude towards QR codes when they are aware of the destination/ information that will be presented? 4. Does one gender have a more positive attitude towards QR codes over the other gender? 5. Does the availability of QR codes prevent or enhance a positive attitude towards QR codes? 6. Are consumers more likely to have a positive attitude towards QR if they know that they will be led to a coupon by scanning? The data was collected through exploratory/descriptive research to record what QR users think about the application and how useful it is to them. The study included a collection of secondary data from various sources as well as a pre-test that was distributed to 15-30 students. Then primary data was collected from an online survey created with appropriate measures
