This paper examines whether management changes caused by the entry of the baby boom into the workforce explain the US productivity slowdown in the 1970s and resurgence in the 1990s. Lucas (1978) suggests that the quality of managers plays a significant role in determining output. If there is heterogeneity across workers and management skill improves with experience, an influx of young workers w...

Three hundred and five traditional college students and 159 baby boomers (40–55 years old) in China participated in the study with Kogan’s Attitude toward Old People [Kogan (1961) Journal of Abnormal and Social Psychology, 62(1), 44–54] being used. Results from ANOVA showed overall, baby boomers held more positive attitudes toward older people than college students. There was a significant inte...

This formalisation contains the proof that there is no anonymous and neutral Social Decision Scheme for at least four voters and alternatives that fulfils both SD-Efficiency and SD-Strategy-Proofness. The proof is a fully structured and quasi-human-redable one. It was derived from the (unstructured) SMT proof of the case for exactly four voters and alternatives by Brandl et al. [1]. Their proof...

The behaviours, attitudes, and work values of three generations of employees may be influenced by their historical, economic, social, and cultural experiences. Work tensions and conflicts are inevitable if the Baby Boomer, generation X, and generation Y employees fail to understand and accept the unique and different characteristics of each group, and to embrace their similarities. If employees...

The baby-step giant-step algorithm, BSGS for short, was proposed by Shanks in order to compute the class number of an imaginary quadratic field. This algorithm is at present known as a very useful tool for computing with respect to finite groups such as the discrete logarithms and counting the number of the elements. Especially, the BSGS is normally made use of counting the rational points on t...

Introduction The clinical problems: Prostate cancer is the most common non-cutaneous cancer and the second most common cause of cancer death in American men. The American cancer society estimates that in 2003, 220,900 new cases for prostate cancer will have been identified [1]. With the increase in the number of older people in the US (the baby-boomers), it is estimated that 450,000 new cases w...

The non-linear nature of string theory on non-trivial backgrounds related to the AdS/CFT correspondence suggests to look for simplifications. Two such simplifications proved to be useful in studying string theory. These are the pp-wave limit which describes point-like strings and the so called “near flat space” limit which connects two different sectors of string theory – pp-waves and “giant ma...

Abstract. In order to improve the steady output of micrgripper, the giant magnetostrictive micrgripper with flexure hinge is taken as the research object . Its structure and working principle are presented .the static performance experiments are done and the better linear work domain is found. On the basis of that the dynamic model of the microgripper is established and the formula of the micro...

– The multipole expansion technique is applied to one of the largest magnetic molecules, Fe30. The molecule’s dipole, toroid and quadrupole magnetic moments are equal to zero (in the absence of magnetic field) so the multipole expansion starts from the octopole moment. Probably the Fe30 molecule is the most symmetrical magnetic body synthesized so far. The magnetization process is considered th...

We consider classical string spectrum of Rt× CP, and construct a family of solutions with residual SU(2) symmetry by the dressing method on SU(4)/U(3) sigma model. All of them obey the square-root type dispersion relation, as is expected from the psu(2|2) symmetry. A single dyonic giant magnon is not found in this approach. [email protected]
