Besides the pledges for expanding uses of biofuels to sustain the humanosphere, abruptly massive needs emerged for sanitizers with turns COVID-19 to a pandemic. Therefore, ethanol is topping the social-demanding, although the three generations of production, from molasses/starch, lignocelluloses, and algae. Owing to the limited-availability of fermentable sugars from these resources, we addressed glycerol as a fourth bio-based carbon resource from biodiesel, soap, and fatty acid industries, which considers as a non-applicable source for bioethanol production. Here, we show the full strategy to generate efficient glycerol fermenting yeast by innovative rewriting the oxidation of cytosolic nicotinamide-adenine-dinucleotide (NADH) by O2-dependent dynamic shuttle while abolishing glycerol biosynthesis route. Besides, imposing a vigorous glycerol-oxidative pathway, the engineered strain demonstrated a breakthrough in conversion efficiency (up to 98%). Its capacity extending to produce up to 90g /l ethanol and > 2 g 1-1 h-1, which promoting the industrial view. Visionary metabolic engineering here provides horizons for further tremendous economic and health benefits with assuring for its enhancing for the other scenarios of biorefineries.SummaryEfficiently fermenting glycerol in yeast was developed by comprehensive engineering the glycerol pathways and rewriting NADH pathways.

Abstract. Grounded in social-psychological literature, this experimental study assessed the effects of two so-called “wise” interventions implemented in a student study program. The interventions took place during the very first week at university, a presumed pivotal phase of transition. A group of 375 freshmen in psychology were randomly assigned to three conditions: control, social belonging, and self-affirmation. Following the intervention, students in the social-belonging condition expressed less social apprehension, a higher social integration, and a stronger intention to persist one month later than the other participants. They also relied more on peers as a source of support when confronted with a study task. Students in the self-affirmation condition felt more self-affirmed at the end of the intervention but didn’t benefit from other lasting effects. The results suggest that some well-timed and well-targeted “wise” interventions could provide lasting positive consequences for student adjustment. The respective merits of social-belonging and self-affirmation interventions are also discussed.

This research deals with the development of  self concept of Hiroko as the main character in Namaku Hiroko by Nh. Dini and tries to identify how Hiroko is portrayed in the story, how she interacts with other characters and whether she is portrayed as a character dominated by ”I” element or  ”Me”  element seen  from sociological and cultural point of view. As a qualitative research in nature, the source of data in this research is the novel Namaku Hiroko (1967) and the data ara analyzed and presented deductively. The result of this analysis shows that in the novel, Hiroko as a fictional character is  portrayed as a girl whose personality  develops and changes drastically from ”Me”  to ”I”. When she was still in the village  l iving with her parents, she was portrayed as a obedient girl who was loyal to the parents, polite and acted in accordance with the social customs. In short, her personality was dominated by ”Me”  self concept. On the other hand, when she moved to the city (Kyoto), she was portrayed as a wild girl  no longer controlled by the social customs. She was  firm and determined totake decisions of  her won  for her future without considering what other people would say about her. She did not want to be treated as object. To put it in another way, her personality is more dominated by the ”I” self concept.

Nas últimas décadas se observa o retorno da religião sob forma de fundamentalismo religioso, utilizando a mídia e instrumentos de pressão política para fazer valer suas crenças, pois diante do receio ao questionamento, os fundamentalistas veem no “outro”, no diferente, uma ameaça a ser combatida e, em alguns casos, extirpada para preservar suas convicções. O presente estudo tem por objetivo discutir as tendências sócio-políticas do fundamentalismo religioso cristão. Para tanto, com método bibliográfico narrativo, visitamos alguns autores em nível nacional e internacional, que abordam as condições que fizeram emergir o fenômeno social do fundamentalismo religioso, sua estruturação e atuação, até suas demandas sócio-políticas. Os resultados apontam que quando se identifica e transfere qualquer responsabilidade pessoal e histórica para as forças externas, o “outro”, entendido como pessoa e/ou instituição, não podemos negar que esse processo alcança dimensões de problema social. Notamos algumas tendências como mudança de movimento religioso para ideologia acirrada, da postura de fiel para militância, do “ad intra” das religiões para demandas “ad extra”, dos altares e púlpitos para ocupações políticas.Palavras-chave: Fundamentalismo Religioso; Protestante; Católico. CHRISTIAN RELIGIOUS FUNDAMENTALISM: SOCIAL-POLITICS TENDENCIESAbstractIn the last decades the return of religion in religious fundamentalism form can be observed, using media and instruments of political pressure, because when facing the fear of questioning, fundamentalists see in the “other”, in the different, a threat to be stopped and, in some cases, extirpated top preserve their convictions.  This study aims to discuss the social-politics tendencies of the Christian religious fundamentalism. For that, with the narrative bibliographic method, we visited some authors of national and international level, that approach the conditions that caused the emergence of the religious fundamentalism social phenomenon, its structure and role, until its social-politics demand. The results show that when any personal or historical responsibility is identified and transferred to external forces, the “other”, understood as person and/or institution, we cannot deny this process reaches dimensions of social problem. We notice some tendencies such as the change of the religious movement to fierce ideology, from the posture of faithful to militancy, from “ad intra” of religions to “ad extra” demands, from the altars and pulpits to political positions.Keywords: Religious Fundamentalism; Protestant; Catholic.

The article considers two versions of D. H. Lawrence’s essay The Theatre: the one which appeared in the English Review in September 1913 and the other one which Lawrence published in his first travel book Twilight in Italy (1916). The latter, considerably revised and expanded, contains a number of new observations and gives a more detailed account of Lawrence’s ideas.Lawrence brings to life the atmosphere inside and outside the theatre in Gargnano, presenting vividly the social structure of this small northern Italian town. He depicts the theatre as a multi-storey stage, combining the interpretation of the plays by Shakespeare, D’Annunzio and Ibsen with psychological portraits of the actors and a presentation of the spectators and their responses to the plays as distinct social groups.Lawrence’s views on the theatre are contextualised by his insights into cinema and its growing popularity.What makes this research original is the fact that it offers a new perspective, aiming to illustrate the social situation inside and outside the theatre whichLawrenceobserved. The author uses the material that has never been published or discussed before such as the handwritten lists of box-holders in Gargnano Theatre, which was offered to Lawrence and his wife Frieda by Mr. Pietro Comboni, and the photographs of the box-panels that decorated the theatre inLawrence’s time.

The present article focuses on one of the Greek delicacies mentioned by Photius and Eustathius, i.e. a Lydian import called kandaulos/kandylos. The dish was developed before the mid. VI th c. BC and named after a Lydian king, Kandaules, who ruled in the VII th c. BC. The delicacy was (via the Ionians) borrowed by the Helens and established itself in Greece sometime in the V th c. It became popular in Hellenistic times. The information we possess allow us to reconstruct two varieties of kandaulos/ kandylos. The first was savoury and consisted of cooked meat, stock, Phrygian cheese, breadcrumbs and dill (or fennel). The other included milk, lard, cheese and honey. The dish is reported to have been costly, prestigious and indicating the social status of those who would eat it. Though there is much evidence suggesting its popularity in antiquity, we lack solid evidence proving that kaunaudlos/kandylos was eaten in Byzantine times. On the other hand, Byzantine authors preserved the most detailed literary data on the delicacy. If it had not been for the Byzantine interest, our competence in the field of Greek cuisine would be even faultier.

AbstractThe authors analyze the changes in value patterns—patriarchy, authoritarianism and nationalism—in Serbia in the context of the social changes that have marked the postsocialist transformation period. They focus on the extent and intensity of two sub-patterns within each of these three basic value patterns: private and public patriarchy, general and specific authoritarianism, organic (natural) and ethnic nationalism. The conclusions about changes in these value patterns are drawn on the basis of three empirical studies conducted in 2003, 2012, and 2018. They show the prevalence of private patriarchy, general authoritarianism, and organic (natural) nationalism over their counterparts. Private patriarchy has weakened, which is largely to be explained by the significant structural changes in Serbia. On the other hand, support of general authoritarianism and organic (natural) nationalism has been on the rise, which clearly mirrors the unfavorable economic and political situation in the country.

Abstract The article examines how the aspects of the social world are enacted in a theater play. The data come from a videotaped performance of a professional theater, portraying a story about a workplace organization going through a personnel training program. The aim of the study is to show how the core theme of the play – the teaming up of the personnel – is constructed in the live performance through a range of interactional means. By focusing on four core episodes of the play, the study on the one hand points out to the multiple changes taking place both within and between the different episodes of the play. On the other hand, the episodes of collective action involving the semiotic resources of singing and dancing are shown to represent the ideals of teamwork in distinct ways. The study contributes to the understanding of socially and politically oriented theater as a distinct, pre-rehearsed social setting and the means and practices that it deploys when enacting the aspects of the contemporary societal issues.
