Spatial Integration and Asymmetric Price Transmission in Selected Iranian Chicken Markets
No full textThis study evaluates pattern of price adjustments in selected spatially separated chicken markets in Iran using weekly price data from 1998:17 to 2006:41 including 441 observations in total. The results of Tsay’s test suggest that threshold behavior characterize spatial price linkages among the selected markets that imply on using the threshold models. We use the multi-dimensional (two and three regime) threshold cointegration of TAR and M-TAR models. Our results confirm the different speed of adjustment in response to positive and negative shocks in every case. We also utilize impulse response function to investigate dynamic patterns of adjustments in response to shocks.Spatial Integration, Price Transmission, Threshold Autoregression, Chicken, International Relations/Trade, Marketing,
The Effects of Silver Nanoparticles Coatings in Effective Drug Delivery: Human Serum Albumin Interaction
No full textBackground & Objective: Silver nanoparticles (AgNPs) are increasingly used in nanomedicine and pharmacy due to their valuable properties. AgNPs are synthesized in various ways. The amount of drug binding to Human Serum Albumin (HSA) as the most abundant protein in the circulatory system would affect the drug’s therapeutic concentration and its availability for intracellular targets. Thus, the purpose of this study was to investigate the effect of coating in the synthesis of AgNPs on their ability to interact with HSA.
Materials & Methods: Fluorescence emission spectroscopy, circular dichroism (CD) spectroscopy, and Zeta potential analysis were used to study the structural effects of HSA after interaction with AgNPs with ethylene glycol dispersion matrix. AgNPs contains sodium citrate stabilizer and uncoated AgNPs.
Results: The fluorescence quenching indicated that AgNPs with ethylene glycol dispersion matrix interacted with HSA with a higher binding constant value compared with two other AgNPs. The CD spectra indicated a reduction in α-helix content of HSA especially after the addition of AgNPs with ethylene glycol dispersion matrix (from 51.45% to 41.71%). The zeta potential analysis showed that the surface charge of HSA was reduced especially after the addition of AgNPs with ethylene glycol dispersion matrix (from -16.73 mV to -11.79 mV).
Conclusion: This study showed that AgNPs with ethylene glycol dispersion matrix interact with HSA more strongly compared with two other AgNPs. This study indicated that the type of coating of AgNPs affects the HSA interaction and consequently affects the nanoparticles transportation and distribution in the blood
Unemployment insurance in Algeria : implications for a labor market in transition
No full textTo predict how Algeria's unemployment crisis will evolve, the author evaluates the Algerian unemployment insurance system's ability to finance itself, to affect employment decisions, and promote enterprise restructuring. The main conclusion is that industrial restructuring has serious and persistent implications for the labor market. In an environment where many equilibria are possible, there is a real danger of reaching a high unemployment equilibrium. The big-bang experience of structural adjustment in Central and Eastern Europe transition economies resulted in large-scale unemployment. Despite considerable restructuring progress, structural rigidities still exist in the labor market, and long-term unemployment has persisted. One advantage of the big-bang approach is adjustment speed, but the resulting unemployment may be too costly for Algeria's economy, especially if it persists. A more modern mixed bang approach would incorporate active employment measures to mitigate entrenched unemployment. The policies will maintain or enhance human capital through work, so idle workers don't lose their skills. Flex-time arrangements would help workers maintain an attachment to the labor force. However minor, such work would help workers avoid the traps of long-term unemployment. Two striking conclusions emerge from the Central and Eastern European experience: a) unemployment is not essential to enterprise restructuring and labor market adjustment;and b) growing long-term unemployment is self-fulfilling and results in higher and persistence unemployment. Although active employment measures are costly and have relatively low rates of return in the short run, they can be marginally effective as part of a long-term strategy.Health Economics&Finance,Labor Policies,Environmental Economics&Policies,Labor Markets,Economic Theory&Research,Environmental Economics&Policies,Labor Markets,Economic Theory&Research,Health Economics&Finance,Banks&Banking Reform

No full textCorporate communication as a governance mechanism: A content analysis of corporate public disclosures
No full textCorporate communication efforts have mainly been viewed as a by-product of governmental regulations and board of directors’ oversight. In this paper, we examine the role of corporate communication as a stand-alone governance mechanism. We introduce a new business-related dictionary and conduct automated textual analysis of over 150,000 electronic documents filed by a sample of firms listed on the S&P/TSX Composite Index from 1999 to the end of 2014. Our findings demonstrate the governing role of corporate communication by documenting the adverse market effects of deviations from the expected level of communication. Moreover, as a governance mechanism, corporate communication shows substitution/complementary relationships with other established governance mechanisms. In addition, we find a non-linear relationship between a firm’s communication efforts and its value and risk levels. Results are robust after controlling for major corporate events (M&A, spin-offs, financial distress and bankruptcy, and significant lawsuits). These findings contribute to corporate governance literature and the understanding of agency theory predictions of communications and disclosures’ economic effects
Corporate communication as a governance mechanism
No full textWe examine whether corporate communication is a stand-alone governance mechanism. Corporate communication is measured by length (to capture the amount), dictionary (to capture the informativeness), and communication index (to capture the diversity of disclosed information). Using content analysis technique on more than 150,000 filings of 98 Canadian firms from 1999 to 2014, we find that firms’ communication have governing powers. Our findings confirm substitution-complementary relationship between corporate communication and board size, independence, education, expertise, CEO duality, frequency of board meetings, gender diversity, institutional ownership, and product market competition. Moreover, we show that negative deviation from the expected transparency is associated with negative changes in Tobin’s Q, confirming the disciplinary role of corporate communications. We also find that communication has an inverted U-shaped association with Tobin’s Q, and a U-shaped association with firm’s risk, showing the non-linearity and existence of an optimum point in communications. Results are robust when controlling for corporate major events (M&A, Spin-offs, Financial distress and bankruptcy, and major lawsuits)
International capital flows : do short-term investment and direct investment differ?
No full textThe authors examine the behavior of four major components of international capital flows in 15 developing and industrial countries. Striking differences in the behavior of the component flows arise in general specifications that allow the flows to interact. For example, the behavior of international short-term investment appears to be sensitive to changes in all the other types of international capital flows, including direct investment, but direct investment appears to be insensitive to such changes. In finding that short-term investment appears to respond more dramatically to disturbances in other capital flows and in other countries than does direct investment, the authors provide empirical support for the conventional notion that short-term investment is"hot money"and direct investment is not.International Terrorism&Counterterrorism,Economic Theory&Research,Payment Systems&Infrastructure,Fiscal&Monetary Policy,Capital Markets and Capital Flows,Financial Intermediation,International Terrorism&Counterterrorism,Economic Theory&Research,Banks&Banking Reform,Capital Flows
