    Notizen: In this study we contribute to the literature by re-examining the effect of control and ownership of controlling shareholder on corporate valuation, and determining which particular mechanism for enhancing voting rights would achieve the negative entrenchment effect. We take Taiwan listed companies, where the ownership concentration structure is similar to that in East Asian countries, as our sample. We find the corporate value is higher when the largest shareholder owns more cash flow rights (ownership), supporting the positive incentive effect. The negative entrenchment effect becomes evident when the largest shareholder's cash flow rights are less than the median. Therefore, if the cash flow rights owned by the largest shareholder are greater than the median, the positive incentive effect will restrain the negative entrenchment effect. In family-controlled companies, the corporate value will conspicuously decrease if the largest shareholder enhances their voting rights through cross-shareholding, deeply participates in management or controls most board of directors.

    Notizen: Prior empirical evidence supports the wealth expropriation hypothesis that weak corporate governance induced by certain types of ownership structures and board composition tends to result in minority interest expropriation. This in turn reduces corporate value. However, it is still unclear whether corporate financial distress is related to these corporate governance characteristics. To answer this question, we adopt three variables to proxy for corporate governance risk, namely, the percentage of directors occupied by the controlling shareholder, the percentage the controlling shareholders shareholding pledged for bank loans (pledge ratio), and the deviation in control away from the cash flow rights. Binary logistic regressions are then fitted to generate dichotomous prediction models. Taiwanese listed firms, characterised by a high degree of ownership concentration, similar to that in most countries, are used as our empirical samples. The evidence suggests that the three variables mentioned above are positively related to the risk for financial distress in the following year. Generally speaking, firms with weak corporate governance are vulnerable to economic downturns and the probability of falling into financial distress increases.

    Notizen: Abstract The activity of antifreeze glycoprotein from the blood serum ofBoreagadus saida was strongly inhibited by ions of organic boronic acids as well as by borate. The activity of nonglycoprotein from the blood serum ofPseudopleuronectus americanus, however, was not similarly inhibited. The inhibition by borate is thus specific for molecules with the carbohydrate moiety.

    Notizen: Summary The polarization properties of the first diffraction order have been measured when single frog fibres are illuminated by laser light. The relative difference in the amplitudes of the orthogonal electric field polarization components (differential field ratio) as well as their phase shift normalized by the pathlength (birefringence) have been obtained from fibres at rest and during fixedend twitches and tetani. The differential field ratio decreased during contraction and the change during a single twitch averaged 69% of that during a companion tetanus. The birefringence of the first order averaged 2.80±0.59×10−3 (mean±SD) at rest and the average decrease during a tetanus was 8.4%±6.4%. The decrease in the differential field ratio upon activation was a decreasing function of sarcomere length, maximum at rest length and falling to zero at about 3.7μm. Differences between the two first diffraction orders were observed for both the differential field ratio and the birefringence. At the time when force had risen to half the value reached at the end of the fast rise of tension, the change in the the differential field ratio lead the tension by about 10–15 ms. The differential field ratio returned to its resting value after the fall of tension. The above results suggest that the differential field ratio is a sensitive indicator of intact fibre structure. The temporal lead in the differential field ratio with respect to tension rise supports models in which crossbridges initially attach in a non-force-producing state.

    Notizen: The solution bebavior of poly-L-proline Form II has been studied in water and aqueous salt solutions by both elastic and quasi-elastic light -scattering techniques. The results of this study suggest that polyproline Form II can exist in water at 24 °C as an associated polymer complex and that certain salts which do not appear to affect the helix integrity, e.g., guanidinium-HCl, resutl in dissociation of the aggregate. Other neutral salts, of the variety effective in mediating unfolding of the Form II helix (e.g., 4M NaClO4) also induce aggregate dissociation, but 4M CaCl2 results in enhanced aggregation of polyproline. Kinetic experiments indicate that a time of 20 hours is necessary for the completion of the “large” to “small” transformation (at 22°C) which is induced by the addition of 4M NaClO4. Thus it appears that neutral salts additives in aqueous solutions of polyproline influence both the state of aggregation and the conformation of this polymer.
