Bioethanol is a biofuel that is mostly used as a replacement for fossil fuels worldwide with yearly production reaching nearly 110 billion liters in 2019. Trends of producing this alternative fuel are rising and maize is considered as one of the best renewable raw materials for the production of fuel ethanol due to the high content of starch in the grain. Taking into account that Serbia is one of the most prominent maize producers in Europe, the surpluses of this crop could be directed towards bioethanol production. Even though there is no organized production and consumption of bioethanol as an automotive fuel in Serbia, the Serbian Government has recently introduced some new regulations regarding biofuels. However, due to the reduction of economic activities since the onset of COVID-19 pandemic in 2020, the global demand for crude oil has fallen sharply, negatively affecting the gasoline demand, and thus for bioethanol, which makes the future of this alternative fuel production notably uncertain.

This article re-examines the effects of culture on national innovation rates. Pointing to the innovation success of some East Asian countries, it argues that the cultural dimension of individualism is not able to fully account for the role of culture in national innovativeness, and there is a need to include a wider set of cultural factors in the analysis. Several competing measures of national innovation performance over the last decade and Hofstede’s measures of culture, as well as their recently revised versions proposed by Minkov and collaborators, are employed to test the hypotheses. The findings show that, apart from individualism, long-term orientation, and flexibility, the dimensions omitted in the prior studies are positive and strong cultural predictors of national innovation intensity, whereas the role of other cultural factors finds little empirical support. The study suggests that there is no single pattern for the impact of culture on national innovation rates that should be taken into account in seeking effective innovation strategies and policies. It also highlights the need to advance the understanding of the causal mechanism between culture and innovativeness to guide further theoretical and empirical analysis.

ABSTRACT Scenedesmus acuminatus, also known as Tetradesmus acuminatus, is a promising green microalga for sustainable production of microalga products, including valuable compounds such as astaxanthin, β-carotene, and lutein, polysaccharides such as β-glucan, and polyunsaturated fatty acids. Here, we report the draft whole-genome sequence of Scenedesmus acuminatus SAG 38.81.

We examined the role of culture and social cynicism beliefs in the transference of an anxious attachment style from mother to romantic partner among a group of undergraduates from the US (n = 200) and Hong Kong (n = 147). The results showed that anxious attachment to mother and to partner was moderately correlated among both cultural groups. However, social cynicism beliefs were found to moderate the relationship between anxious attachment to mother and attachment to partner among U.S. but not Hong Kong Chinese participants. This observed differential effect of social cynicism beliefs could be explained by differences in self-direction values across the 2 cultural groups. The findings in the study are of theoretical significance as they provide insights for further research on the influences of cultural variables and personal beliefs on attachment transference.

The role of anatomical traits in carbohydrate accumulation was investigated in fruit of Actinidia deliciosa (A. Chev.) C. F. Liang et A. R. Ferguson (kiwifruit) var. deliciosa by comparing high and low dry matter (DM) accumulating genotypes. DM was shown previously to be correlated with starch concentration in these fruit. Volume proportions of the three fruit tissues (outer pericarp, inner pericarp and central core) did not vary significantly between genotypes or contribute to variation in total fruit DM. The outer pericarp of the kiwifruit berry contains both small and large cells: the size of these cells was not correlated with final fruit size. In high DM genotypes, the relative volume of outer pericarp tissue occupied by small cells (50%) was significantly greater than that in low DM genotypes (43%). Small cells have a higher starch concentration than large cells: the larger proportion of small cells in the outer pericarp of fruit from high DM genotypes accounted for approximately +25% of the measured differences in fruit starch concentration between high and low DM genotypes. We conclude that, although anatomical traits contribute to variation in fruit starch concentration between kiwifruit genotypes, differences in starch content per small cell are important and worthy of further investigation. This is the first time anatomical investigations have been used to examine differences in fruit carbohydrate accumulation in kiwifruit.

The associations between insecure attachment, negative parental behaviors, and social anxiety in childhood and adolescence have long been established theoretically and documented by empirical research. Still, it is clear that those associations operate through various moderators that should be addressed, among which are societal, economical, and cultural variables whose effect can be neither ignored nor overlooked. The vicissitudes of individual psychological development are shaped by environments, both physical and symbolic, in which those individuals are embedded: indeed, the cross-cultural studies that compared between Western and non-Western samples consistently reveal interrelatedness between secure/insecure attachments, parenting practices, and socioeconomic and cultural influences. In the light of the above, the present article addresses the interplay between insecure attachment, parental behaviors, and social anxiety in children as a multi-layered constellation of risk-factors which are informed by the broad network of socioeconomic and cultural dimensions. The integrative review of extensive body of literature demonstrates that this constellation cannot be complete without elucidating the role of fathers in parenting that may contribute to developing social anxiety, as well as without taking into consideration characteristics of cultures and society which shape and inform both parental practices and their perceptions.
