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...

Plant tissue culture is an alternative method of commercial propagation and is being used widely for the commercial propagation of a large number of plant species, including many medicinal plants. Somatic embryogenesis is a process by which asexual or somatic cells are induced to form embryos in culture. Somatic embryogenesis is a multi-step regeneration process starting with formation of pro-e...

Mycobacterium tuberculosis culture, a critical technique for routine diagnosis of tuberculosis, takes more than two weeks. Here, step-by-step improvements in the protocol including a new medium, microaerophlic atmosphere or ascorbic-acid supplement and autofluorescence detection dramatically shortened this delay. In the best case, primary culture and rifampicin susceptibility testing were achie...

OBJECTIVE To study whether a culture medium that allows undisturbed culture supports human embryo development to the blastocyst stage equivalently to a well-established sequential media. DESIGN Randomized, double-blinded sibling trial. SETTING Independent in vitro fertilization (IVF) clinics. PATIENT(S) One hundred twenty-eight patients, with 1,356 zygotes randomized into two study arms. ...
