Abstract The systematization of knowledge for educational practice entered a new era in the wake of Ramism. Innovative encyclopedic approaches and textbooks also surfaced in the field of Kabbalah. This article discusses Moses Zacuto’s approach to the kabbalistic genre of reference books and the impact of Lurianic Kabbalah. Against the backdrop of the reception of Ramist ideas and building upon the interaction between Kabbalah and logic in Abraham Cohen de Herrera’s Spanish books, two works in particular, which Zacuto left in an apparently unfinished state in manuscript form, are analyzed in this context: Em la-Binah and Remez ha-Romez. Both works differ from traditional reference books, and Em la-Binah in particular will be examined in order to answer the question of how Zacuto’s strategy for commonplace learning worked in a Lurianic textbook in progress.

In the mid-nineteenth century Virchow revolutionized pathology by introduction of the concept of “cellular pathology”. Today, a century later, this term has increasing significance in health and disease. We now are in the beginning of a new era in pathology, one which might well be termed “organelle pathology” or “subcellular pathology”. The impact of lysosomal diseases on clinical medicine exemplifies this role of pathology of organelles in elucidation of disease today.Another aspect of cell organelles of prime importance is their pathologic alteration by drugs, toxins, hormones and malnutrition. The sensitivity of cell organelles to minute alterations in their environment offers an accurate evaluation of the site of action of drugs in the study of both function and toxicity. Examples of mitochondrial lesions include the effect of DDD on the adrenal cortex, riboflavin deficiency on liver cells, elevated blood ammonia on the neuron and some 8-aminoquinolines on myocardium.

In the present study, the impact strength, flexural modulus, and wear rate of poly methyl methacrylate (PMMA) with eggshell powder (ESP) composites have been investigated. The PMMA used as a matrix material reinforced with ESP at two different states (including untreated eggshell powder (UTESP) and treated eggshell powder (TESP)). Both UTESP and TESP were mixed with PMMA at different weight fractions ranged from (1-5) wt.%. The results revealed that the mechanical properties of the PMMA/ESP composites were enhanced steadily with increasing eggshell contents. The samples with 5 wt.% of UTESP and TESP additions give the maximum values of impact strength, about twice the value of the pure PMMA sample. The calcination process of eggshells powders gives better properties of the PMMA samples compared with the UTESP at the same weight fraction due to improvements in the interface bond between the matrix and particles. The wear characteristics of the PMMA composites decrease by about 57% with increases the weight fraction of TESP up to 5 wt.%. The flexural modulus values are slightly enhanced by increasing of the ESP contents in the PMMA composites.

: Nanobionics involves the improvement of plant or plant productivity using nanomaterials. Growth of a plant from a seed encompasses various factors which are directly or indirectly dependent upon the imbibition of micro and macro nutrients and vital elements from the soil. Since most of the nutrition is physiologically unavailable to the plants, it leads to mineral deficiencies in plant and mineral toxicity in soil. Either ways, it is not a favourable situation for the microcosom. The new era of nanotechnology offers a potential solution to the availability of the nutrients to the plants due to its unique chemical and physical properties of nanoparticles. Positive and negative impact of these nanoparticles on seed quality and plant growth varies according to the specific properties of nanoparticles. The present review is an attempt to summarize the impact of nanobionics in agriculture.

Deaf and hard of hearing (DHH) children have been claimed to lag behind their hearing peers in various domains of cognitive development, especially in implicit learning, executive function, and working memory. Two major accounts of these deficits have been proposed: one based on a lack of auditory access, and one based on a lack of language access. This chapter reviews these theories in relation to the available evidence and concludes that there is little evidence of direct effects of diminished auditory access on cognitive development that could not also be explained by diminished language access. Specifically, reports of deficits in implicit learning are not broadly replicable. Some differences in executive function do stem from deafness itself but are not necessarily deficits. Where clinically relevant deficits in executive function are observed, they are inconsistent with the predictions of accounts based on auditory access, but consistent with accounts based on language access. Deaf–hearing differences on verbal working memory tasks may indicate problems with perception and/or language, rather than with working memory. Deaf–hearing differences on nonverbal tasks are more consistent with accounts based on language access, but much more study is needed in this area. The chapter concludes by considering the implications of these findings for psychological theory and for clinical/educational practice and by identifying high-priority targets for future research.

AbstractIn this paper, we attempt to show some consequences of bringing the body back into higher education, through the use of performing arts in the curricular context of scientific programs. We start by arguing that dominant traditions in higher education reproduced the mind-body dualism that shaped the social matrix of meanings on knowledge transmission. We highlight the limits of the modern disembodied and decontextualized reason and suggest that, considering the students’ and teachers’ bodies as non-relevant aspects, or even obstacles, leads to the invisibilization of fundamental aspects involved in teaching and learning processes. We thus conducted a study, from a socio-cultural perspective, in which we analyse the emerging matrix of meanings given to the body and bodily engagement by students, through a systematic qualitative analysis of 47 personal diaries. We structured the results and the discussion around five interpretative axes: (1) the production of diaries enables historicization, while the richness of bodily experience expands the boundaries of diaries into non-textual modalities; (2) curricular context modulates the emergent meanings of the body; (3) physical and symbolic spaces guide the matrix of bodily meanings; (4) the bodily dimension of the courses facilitates the emergence of an emotional dimension to get in touch with others and to register one's own emotional experiences; and (5) the body functions as a condition for biographical continuity. These axes are discussed under the light of the general process of consciousness-raising and resignification of the situated body in the educational practice.

Although the global Covid-19 pandemic is still affecting our lives enormously, we know that a new era of deep reflection about ‘normality’, our planet and our existence on it has also begun. The ‘Education in Europe and the Covid-19 Pandemic’ double Special Issue intends to be part of this reflexive discussion about the post-pandemic European education policy and research space. This is a space shaped continuously by crises and opportunities, by utopias of a shared progressive and liberal education for all, but also the dystopias of nationalism, populism, climate destruction and now a global health emergency. This editorial offers an overview of the current crisis context and of the articles; further, it positions the journal within the post-pandemic research and policy debate about how to understand the impact of the pandemic on the changing forms of education and its enduring inequalities.

This review presents the comprehensive knowledge about the bidirectional relationship between polyphenols and the gut microbiome. The first part is related to polyphenols’ impacts on various microorganisms, especially bacteria, and their influence on intestinal pathogens. The research data on the mechanisms of polyphenol action were collected together and organized. The impact of various polyphenols groups on intestinal bacteria both on the whole “microbiota” and on particular species, including probiotics, are presented. Moreover, the impact of polyphenols present in food (bound to the matrix) was compared with the purified polyphenols (such as in dietary supplements) as well as polyphenols in the form of derivatives (such as glycosides) with those in the form of aglycones. The second part of the paper discusses in detail the mechanisms (pathways) and the role of bacterial biotransformation of the most important groups of polyphenols, including the production of bioactive metabolites with a significant impact on the human organism (both positive and negative).

The purpose of this paper is to highlight that, in order to assess the availability of different HVDC cable transmission systems, a more detailed characterization of the cable management significantly affects the availability estimation since the cable represents one of the most critical elements of such systems. The analyzed case study consists of a multi-terminal direct current system based on both line commutated converter and voltage source converter technologies in different configurations, whose availability is computed for different transmitted power capacities. For these analyses, the matrix-based reliability estimation method is exploited together with the Monte Carlo approach and the Markov state space one. This paper shows how reliability analysis requires a deep knowledge of the real installation conditions. The impact of these conditions on the reliability evaluation and the involved benefits are also presented.

Purpose – The purpose of this paper is to provide for Western educators of international Chinese and Confucian Heritage Culture (CHC) students the first integrated review of kiasu, the “fear of missing out”, and its consequences for learning, teaching, and future research. Design/methodology/approach – A review of the economic importance of international Chinese students is provided, followed by consideration of the pedagogical consequences of restricted participation in educational activities by the so-called “silent Chinese student”. Examination of research on international Chinese students and their source cultures established significant gaps and misunderstandings in the generally accepted understandings of CHCs, especially with respect to the actual practices used in Western and Chinese teaching. More importantly, the participation-related implications of kiasu within the context of broader cultural characteristics are described and implications drawn for teaching practices and research. Findings – While many Western university teachers are aware of the “silent Chinese student” phenomenon, few understand its underlying reasons, especially the kiasu mindset and its relationship to other cultural elements. Kiasu actively impedes the interaction of international Chinese students with their teachers and restricts collaboration with peers, thereby limiting educational achievement. Specific tactics for amelioration are reviewed and recommendations are provided, while an agenda for future research is outlined. Practical implications – Western teachers need to normalise and encourage Chinese student participation in class activities using tactics that have been demonstrated to improve outcomes for Chinese students, but that also assist students generally. These include both within-class and electronic interaction tools. Social implications – More culturally sensitive understanding of the impact of cultural differences on teaching effectiveness. While some effective responses to these already exist, further research is needed to expand the skill-set of Western teachers who work with international Chinese students. Originality/value – This paper provides the first systematic integration of the kiasu phenomenon with educational practice and research.
