Social life is a key feature in humans; without it, language, science, and technology would not have appeared. The inclination to engage with others is also a main source of pleasure and pain and as such a key factor for quality of life. In this paper, I shall present current knowledge on the evolutionary trajectory leading to the four main types of relations: parent–child, pair-bonding, kinship, and social life (bonding between non-kin for purposes other than breeding). These relationships are not unique to humans; they have evolved independently multiple times across the animal kingdom. In our lineage, the origins of parent–child bonding may be traced back to the early amniotes some 320 Mya (million years ago). Pair-bonding and social life most likely evolved recently. Understanding how these affiliations are rooted in the brain, particularly the role of feelings, provides valuable insights that can help us improve society.

With the rise of individualism as a social trend and the wide use of the Internet and social media, today’s customers increasingly want to design and build unique products that fit their individual preferences and needs. Mass individualization is defined as a manufacturing paradigm that aims to produce individualized products cost-effectively. This paradigm differs from the previous paradigms in which the manufacturing company designed and manufactured the products, and the customer chose a product. In the mass individualization paradigm, the customers will be actively involved in product design, and the manufacturer will produce a unique product for each customer at a reasonable cost and of reliable quality. Due to the need for smooth communication and interactions between the buyer and the factory, new factories for individualized products will be located near potential buyers, which will have a significant impact on local economies. This entry explores the relationship between mass individualization and other emerging manufacturing paradigms and concepts in the Industry 4.0/5.0 era, and discusses how smart factories can improve manufacturing efficiency and facilitate the realization of the mass individualization paradigm.

Triticale, a hybrid of wheat and rye, is one of the most promising grain crops. In terms of productivity, the level of metabolizable energy, and the composition of essential amino acids, triticale surpasses rye and is not inferior to wheat. It is resistant to the most dangerous diseases and pests. In terms of nutritional value, triticale can compete with wheat, corn, sorghum, and barley. The presence, however, of antinutrients in triticale such as non-starch polysaccharides, alkylresorcinols, and trypsin inhibitors significantly reduces the biological value of this crop. In the global practice of compound feed production, there are many methods and technologies for processing grain raw materials to increase their nutritional value. Enzymatic treatment and extrusion technologies are worthy of special attention. The high content of triticale in the compound feed of poultry breeder flocks should be used effectively, taking into account the characteristics of triticale varieties and climatic conditions. An optimal triticale level in feed (15% for layer and broiler chicks) may improve body weight gain and reduce feed costs when raising replacement young stock. Layer breeder flocks fed a 20% triticale-based diet may have increased egg production, high viability, and flock uniformity. Producing triticale–soy and triticale–sunflower extrudates and supplementing the diet of poultry flocks with essential amino acids represent promising avenues for maximizing the benefits of triticale. Innovative methods of achieving this goal should be further developed and put into practice, particularly given the expansion of triticale’s cultivation areas.

Nematophagous fungi (NFs), which are responsible for soil suppression of plant-parasitic nematodes, are multitrophic biocontrol agents. This raises the question of the transition between lifestyles (e.g., endophytism vs. egg parasitism). The NF Pochonia chlamydosporia colonises food crops and promotes their growth and yield. When colonising the plant, P. chlamydosporia induces the plant immunity (PI). However, it also evades the PI. To do this, both endophytic NF and pathogenic fungi (PF) secrete LysM effectors (LysM-effs). LysM effectors have been shown to have diverse functions in different organisms, including the protection of fungal chitin from plant chitinases. P. chlamydosporia is resistant to chitosan, which modulates gene expression in fungi and plants and has antimicrobial properties. P. chlamydosporia chitin deacetylases (CDA) and chitosanases (CSN) also help P. chlamydosporia evade plant immunity, resist exogenous chitosan, and are induced during fungal infection of nematode eggs. NF-chitosan formulations are new biomanagement tools against plant parasitic nematodes, fungal wilt pathogens and insect pests that currently threaten food security crops. Furthermore, omics techniques are useful tools to elucidate the role of CDAs, CSNs, LysM-effs, adhesion proteins and carbohydrate-active enzymes in pathogen–BCA–plant interactions, adhesion and infection to nematode eggs and their modulation by chitosan.

Inclusive supervision is an approach to supervision that prioritizes multicultural competencies and an ethic of inclusion. Inclusivity in doctoral (or PhD) supervision is of key significance due to the collaborative nature of the relationship between supervisors and supervisees. Scant research has been conducted that considers the multiple, intersectional influences and their impact within this relationship. This study employs a rapid review method to synthesize findings on the research evidence encapsulating inclusive doctoral supervision. A search of academic literature spanning the last ten years (2013–2023) led to the inclusion of nine empirical, qualitative research studies on inclusive supervision. A synthesis of the findings resulted in five key challenges to inclusive supervision that diverse students face: power dynamics and feedback, a lack of belonging and support, a racial lens on academic competence, (mis)understandings of cultural differences, and communication and language barriers. In discussing these findings, we employ an intersectional lens and introduce a conceptual framework for an inclusive collaboration between supervisors and supervisees.

Behavior mapping is the systematic observation of people using their environments. The Smart Social Spaces research project, recently completed in Sydney, Australia, is used as a vehicle to illustrate the usefulness of this method for understanding the relationships between people and public spaces in cities. Behavior mapping was the central method used to establish what impact the inclusion of smart technology and street furniture had on people’s use of two public spaces. Using this method, it is possible to record real-time patterns of people’s use of public space, enabling local authorities to better support the social use of public space and the management of its infrastructure.

The aim of this systematic review is to study the effects of Astragalus membranaceus (Huangqi) supplementation for sports activity and physical performance. PubMed, EMBASE, Web of Science, Cochrane Library, and Google Scholar were systematically searched for relevant studies from inception up until October 2023. Eleven clinical studies were considered eligible for inclusion (six of them involved the administration of Huangqi alone, while, in the remaining trials, this herb was supplemented in combination with other remedies). On average, the number of study participants ranged from 8 to 120, and the sports activities practiced by the subjects included martial arts, mountain hiking, basketball, rowing, running, aerobic exercises, and strength training. When a dried extract was used, Astragalus was taken at a daily dose of 1 to 4 g for several weeks. Huangqi supplementation was associated with improvements in aerobic performance, oxidative status, reticulocytes percentage, and response to acclimatization, without a specific effect on the athletes’ strength. Better post-exercise immune functions were also observed, especially with regard to NK cell activity, IL-2 levels, CD4+/CD8+ ratio, and lymphocyte turnover. No adverse effects were described. In conclusion, Astragalus supplementation has the potential to decrease fatigue, enhance aerobic performance, and mitigate post-exercise immune suppression in athletes. It is advisable to conduct additional research on the subject to enhance the robustness of the existing evidence through larger-scale controlled trials.
本系统综述旨在研究补充黄芪对体育活动和身体表现的影响。我们系统地检索了 PubMed、EMBASE、Web of Science、Cochrane Library 和 Google Scholar 上从开始到 2023 年 10 月的相关研究。有 11 项临床研究被认为符合纳入条件（其中 6 项涉及单独服用黄芪，而在其余试验中，黄芪与其他药材一起服用）。参与研究的人数平均为 8 至 120 人，受试者从事的体育活动包括武术、登山、篮球、划船、跑步、有氧运动和力量训练。在使用黄芪干提取物时，每天服用 1 至 4 克，连续服用数周。补充黄芪后，运动员的有氧运动表现、氧化状态、网状细胞百分比和适应性反应都有所改善，但对运动员的力量没有具体影响。此外，还观察到运动后免疫功能有所改善，尤其是在 NK 细胞活性、IL-2 水平、CD4+/CD8+ 比率和淋巴细胞周转率方面。没有发现任何不良反应。总之，补充黄芪具有减轻疲劳、提高有氧运动表现和缓解运动员运动后免疫抑制的潜力。建议对该主题进行更多研究，通过更大规模的对照试验来增强现有证据的可靠性。

The rumen is the largest of the four chambers of the “stomach” in ruminant animals, which harbors an incredibly dense, diverse, and dynamic microbial community crucial for feedstuff degradation, animal health, and production. The primary objective of this article is to enhance knowledge and comprehension of rumen microbiology by providing an introductory-level overview of the field of rumen microbiology. Ruminants possess a distinctive digestive system optimized for the microbial breakdown of complex plant materials. The ruminant ”stomach” consists of four chambers (e.g., reticulum, rumen, omasum, and abomasum), which is home to a microbial population that degrades feedstuffs consumed by ruminant animals. Dr. Robert Hungate and Dr. Marvin Bryant’s groundbreaking research in the 1960s laid the foundation for understanding the function of the ruminal microbial ecosystem. Recent advancements (e.g., next-generation sequencing) have provided the field with deeper insight into populations, boosting our understanding of how the microbial population of the rumen functions in a variety of conditions. The ruminal microbial ecosystem is comprised of bacteria, along with archaea, protozoa, bacteriophage, and fungi, each contributing to the symbiotic relationship between the microbial ecosystem and the host animal that is essential for optimal animal health and efficient animal production. Traditional anaerobic growth techniques have facilitated the study of individual anaerobic bacteria but have been limited by dependence on growth in laboratory conditions. The development of 16S rRNA sequencing allows the identification of microbial populations that cannot be grown and allows an unbiased view of microbial diversity. Diet shapes the rumen microbial population composition, influencing animal production metrics such as feed efficiency, methane emissions, and immunological functions. Feed additives (e.g., essential oils, eubiotics) hold promise by manipulating and unraveling the microbial biochemical potential for improving animal health, feed efficiency, environmental impacts, and overall production sustainability. Future research impacts include the development of probiotics, prebiotics, and genetic strategies for optimizing the rumen microbiome’s multifaceted impacts.
