Vitellogenin is a yolk precursor protein in most oviparous females. In the advanced eusocial honeybee, Apis mellifera (Hymenoptera: Apidae), vitellogenin has recently attracted much interest as this protein, in addition to a classical function in oocyte development in the reproductive queen caste, has evolved functions in the facultatively sterile female worker caste not documented in other spe...

background: as a zoonotic pathogen, encephalitozoon cuniculi is a cause of serious disease in animals and people. the present study was to evaluate the health status examination of this seropositive animal care worker in our pre-vious study. methods: blood samples were taken from five workers. cia test was ap-plied to detect antibodies against e. cuniculi in blood serum. the indirect immunofluo...

We investigate the design of electronic dispersion compensation (EDC) using full optical-field reconstruction in 10Gbit/s on-off keyed transmission systems limited by optical signal-to-noise ratio (OSNR). By effectively suppressing the impairment due to low-frequency component amplification in phase reconstruction, properly designing the transmission system configuration to combat fiber nonline...

[Purpose] This study was conducted to examine physical status and life satisfaction of workers in Korea. [Subjects] In total, 25,455 workers from eight geographical areas were evaluated from 2007 to 2008. [Methods] Physical status of the subjects was measured based on cardiopulmonary endurance, muscular strength, muscular endurance, flexibility, and explosive muscular strength, and a life satis...

We model long-run firm performance, management compensation, and corporate governance in a dynamic, nonstationary world. We show that managerial compensation and governance policies, which, in a single-period context, can best be rationalized by self-serving managerial influence over board policy, are shareholder-wealth maximizing in a dynamic setting. For example, shareholder wealth is maximiz...

In 2009, the Dutch government launched the Wikiwijs project to increase the use, development and sharing of digital learning materials. Wikiwijs mainly offers Open Educational Resources (OER) through a freely accessible website. Although not all resources are freely available, most of Wikiwijs’s learning materials are published under an open licence. Even though part of the educational resource...

This paper introduces a new measure of management overconfidence, overconfident tone, and shows its association with excess investments, larger share repurchases, and higher stock portions in CEO compensations. Overconfident tone is composed of abnormal positivity and abnormal certainty. They are calculated by dividing conference call transcripts into management parts and analyst parts, and sep...

Two auditory feedback perturbation experiments were conducted to examine the nature of control of the first two formants in vowels. In the first experiment, talkers heard their auditory feedback with either F1 or F2 shifted in frequency. Talkers altered production of the perturbed formant by changing its frequency in the opposite direction to the perturbation but did not produce a correlated al...

Many self-report measures of attitudes, beliefs, personality, and pathology include items whose responses can be easily manipulated or distorted, as an example in order to give a positive impression to others, to obtain financial compensation, to avoid being charged with a crime, to get a job, or else. This fact confronts both researchers and practitioners with the crucial problem of biases yie...
