The impact of top management team tenure heterogeneity on declining firm's innovation efficiency
<p>A firm maybe experiences a flourishing or declining period, and it also probably survives or even dies in future. Most firms have experienced decline in their development process. The impact of demand contraction and COVID-19 has caused more firms to face decline. Under the dilemma of resources reduction and recovery, the declining firm pays more and more attention to the efficient utilization of limited resources. It attempts to achieve turnaround through CEO substitution, adjustment of ownership concentration, innovation-oriented and other strategies. Based on Upper echelons theory and resource-based view, using the data of A-share listed manufacturing firms in Shanghai and Shenzhen from 2015 to 2019, the impacts of TMT tenure heterogeneity and ownership concentration on the innovation efficiency were investigated. The results show that the TMT tenure heterogeneity promotes the innovation efficiency of declining firms, while the relatively centralized ownership structure negatively moderates this effect. The robustness analysis of variable replacement and the solving of endogenous problem also further support this conclusion. This study not only enriches the application areas of Upper echelons theory, but also provides practical guideline for declining firms to replace top management members and to dilute equity in order to achieve recovery.</p>

Analysis of The Influence of Country Sustainability Performance on Stock Returns in The Top 5 Asian and European Countries
<p>This paper aims to investigate the influence of a country's sustainability performance on yearly stock returns in the top 5 Asian and European countries from 2019 to 2022. Sustainability performance is proxied by four variables: ESG score, green bonds, air quality index (AQI), and energy consumption. Stock returns are measured using stock prices from the stock exchange of the respective country. The study employs quantitative research methods, using multiple regression analysis with STATA software to test the hypotheses concerning the relationship between dependent and independent variables, with a total of 40 observations. The results reveal a significant positive relationship between ESG score and AQI with yearly stock returns, whereas energy consumption shows an insignificant positive relationship. In contrast, Green bonds have an insignificant negative relationship with yearly stock returns. These findings are useful for international investors and governments in making informed overseas stock investment decisions and understanding the importance of sustainability performance in improving the stock market condition.</p>

FIGURE 5. Top. NRM 54834, Neotype Lampris guttatus, 100.5 cm SL, Bormes-les-Mimosas, France. Bottom. MOM POI- 0004791, Paraneotype Lampris guttatus, 97 cm SL, Northeast Atlantic, landed in Denmark. Note that specimen was frozen for several years before examination and color pattern is abnormal due to freezing process. Opahs are known to have a sexually dimorphic characteristic of an enlarged abdomen in males. MOM POI-0004791 was confirmed as female and we surmise that NRM 54834 is a male.

Neural correlates of top-down modulation of haptic shape versus roughness perception
<p>Exploring an object’s shape by touch also renders information about its surface roughness. It has been suggested that shape and roughness are processed distinctly in the brain, a result based on comparing brain activation when exploring objects that differed in one of these features. To investigate the neural mechanisms of top-down control on haptic perception of shape and roughness, we presented the same multidimensional objects but varied the relevance of each feature. Specifically, participants explored two objects that varied in shape (oblongness of cuboids) and surface roughness. They either had to compare the shape or the roughness in an alternative-forced-choice-task. Moreover, we examined whether the activation strength of the identified brain regions as measured by functional magnetic resonance imaging (fMRI) can predict the behavioral performance in the haptic discrimination task. We observed a widespread network of activation for shape and roughness perception comprising bilateral pre- and postcentral gyrus, cerebellum, and insula. Task-relevance of the object’s shape increased activation in the right supramarginal gyrus (SMG/BA40) and the right precentral gyrus (PreCG/BA44) suggesting that activation in these areas does not merely reflect stimulus-driven processes, such as exploring shape, but also entails top-down controlled processes driven by task-relevance. Moreover, the strength of the SMG/PreCG activation predicted individual performance in the shape but not in the roughness discrimination task. No activation was found for the reversed contrast (roughness > shape). We conclude that macrogeometric properties, such as shape, can be modulated by top-down mechanisms whereas roughness, a microgeometric feature, seems to be processed automatically.</p>
