Abstract Studying the phenotypic variation of organisms along environmental gradients can provide insight into the influences of specific environmental factors. Mongolia, which is distributed across three different biomes, is an ideal location for studying the mechanisms that underlie such phenotypic variation over a large range of climate. The present study examined the variation in shape and size of the body in a ball-rolling dung beetle, Gymnopleurus mopsus (Pallas), in Mongolia and investigated the effects of climate on the species’ morphology. A total of 290 individuals were collected from seven sites and were analysed using multivariate and regression approaches, as well as geometric morphometrics. Body shape and size varied across the study sites and between the different biomes. Populations from the desert-steppe region had thinner bodies and longer heads than those from the steppe region, possibly to facilitate burrowing. Variation in the species’ body size followed a pattern that was the converse of Bergmann’s rule and, thus, might increase heat capacity and enhance thermoregulation ability in the desert-steppe region. Accordingly, the results of the present study provide novel insight into the influence of climate on the variation of dung beetle phenotypes.

Engystomops Pustulosus

This paper evaluated the intraspecific variation and diet of Engystomops pustulosus in three localities (Colosó, Santa Inés, and El Roble) of the department of Sucre, Colombia. Thirty specimens were collected by locality and the diet composition was determined. We characterized the phenotypic variation by means of skull geometric morphometrics and ten body measures. Finally, the relationship between morphogeometric variables (shape and size) and diet were evaluated. We found significant differences between skull conformation and localities, and between localities and the centroid size. Termites were the most important type of prey, followed by ants and mites. The diet composition did not correlate with the body measures; however, an analysis of Partial Least-Squares showed a correlation between the composition of the diet and skull conformation.

Abstract Dung beetles can perform a number of versatile behaviours, including walking and dung ball rolling. While different walking and running gaits of dung beetles have been described in previous literature, little is known about their ball rolling gaits. From behavioural experiments and video recordings of the beetle Scarabaeus (Kheper) lamarcki, we analysed and identified four underlying rules for leg coordination during ball rolling. The rules describe the alternation of the front legs and protraction waves of the middle and hind legs. We found that while rolling a ball backwards, the front legs are decoupled or loosely coupled from the other legs, resulting in a non-standard gait, in contrast to previously described tripod and gallop walking gaits in dung beetles. This provides insight into the principles of leg coordination in dung beetle ball rolling behaviour and its underlying rules. The proposed rules can be used as a basis for further investigation into ball rolling behaviours on more complex terrain (e.g., uneven terrain and slopes). Additionally, the rules can also be used to guide the development of control mechanisms for bio-inspired ball rolling robots.

The future of medicine belongs to immunology and alergology. I tried to not be too wide in description, but on the other hand to mention the most important concepts of alergology to make access to these diseases more understandable, logical and more useful for our patients, that without complex pathophysiology and mechanism of immune reaction,we gain some basic insight into immunological principles. The name allergy to medicine was introduced by Pirquet in 1906, and is of Greek origin (allos-other + ergon-act; different reaction), essentially representing the reaction of an organism to a substance that has already been in contact with it, and manifested as a specific response thatmanifests as either a heightened reaction, a hypersensitivity, or as a reduced reaction immunity. Synonyms for hypersensitivity are: altered reactivity, reaction, hypersensitivity. The word sensitization comes from the Latin (sensibilitas, atis, f.), which means sensibility,sensitivity, and has retained that meaning in medical vocabulary, while in immunology and allergology this term implies the creation of hypersensitivity to an antigen. Antigen comes from the Greek words, anti-anti + genos-genus, the opposite, anti-substance substance that causes the body to produce antibodies.

This chapter explores Schopenhauer’s concept of force, which lies at the root of his philosophy. It is force in nature and thus in natural science that is inexplicable and grabs Schopenhauer’s attention. To answer the question of what this inexplicable term is at the root of all causation, Schopenhauer looks to the will within us. Through will, he maintains that we gain immediate insight into forces in nature and hence into the thing in itself at the core of everything and all things. Will is thus Schopenhauer’s attempt to answer the question of the essence of appearance. Yet will, as it turns out, cannot be known immediately as it is subject to time, and the acts of will, which we experience within us, do not correlate immediately with the actions of the body (as Schopenhauer had originally postulated). Hence, the acts of will do not lead to an explanation of force, which is at the root of causation in nature. Schopenhauer sets out to explain what is at the root of all appearances, derived from the question of an original cause, or as Schopenhauer states “the cause of causation,” but cannot determine this essence other than by stating that it is will; a will, however, that cannot be immediately known.

Postmortem studies are crucial for providing insight into emergent diseases. However, a complete autopsy is frequently not feasible in highly transmissible diseases due to biohazard challenges. Minimally invasive autopsy (MIA) is a needle-based approach aimed at collecting samples of key organs without opening the body, which may be a valid alternative in these cases. We aimed to: a) provide biosafety guidelines for conducting MIAs in COVID-19 cases, b) compare the performance of MIA versus complete autopsy, and c) evaluate the safety of the procedure. Between October and December 2020, MIAs were conducted in six deceased patients with PCR-confirmed COVID-19, in a basic autopsy room, with reinforced personal protective equipment. Samples from the lungs and key organs were successfully obtained in all cases. A complete autopsy was performed on the same body immediately after the MIA. The diagnoses of the MIA matched those of the complete autopsy. In four patients, COVID-19 was the main cause of death, being responsible for the different stages of diffuse alveolar damage. No COVID-19 infection was detected in the personnel performing the MIAs or complete autopsies. In conclusion, MIA might be a feasible, adequate and safe alternative for cause of death investigation in COVID-19 cases.

Shape And Size

AbstractAutonomous mobile robots that operate in environments with people are expected to be able to deal with human proxemics and social distances. Previous research investigated how robots can approach persons or how to implement human-aware navigation algorithms. However, experimental research on how robots can avoid a person in a comfortable way is largely missing. The aim of the current work is to experimentally determine the shape and size of personal space of a human passed by a robot. In two studies, both a humanoid as well as a non-humanoid robot were used to pass a person at different sides and distances, after which they were asked to rate their perceived comfort. As expected, perceived comfort increases with distance. However, the shape was not circular: passing at the back of a person is more uncomfortable compared to passing at the front, especially in the case of the humanoid robot. These results give us more insight into the shape and size of personal space in human–robot interaction. Furthermore, they can serve as necessary input to human-aware navigation algorithms for autonomous mobile robots in which human comfort is traded off with efficiency goals.

PurposeThis paper aims to provide a valid insight into consumers' minds while considering word of mouth (WOM), brand image and uniqueness as independent variables while considering the tourism industry as the primary stakeholder.Design/methodology/approachThe study adopts qualitative research methods and data collected from 1,033 respondents using convenience sampling methodology. The data are collected from different tourists spots in China and Pakistan. The PROCESS macro was utilized in this study using SPSS version 25.0 to inspect the impacts by using Model 4 and the conditional effects indirectly by utilizing Model 14.FindingsCustomer's intimacy, search for novel and unexplored destinations highlight WOM interactions and perceived service value. Service value, interactional justice and professional attitude of hotel management mediated all the given relationships significantly. The brand image does not mediate any significant associations. Perceived service value and brand image predict customer's loyalty, and WOM is the direct measure of their intentions, and these variables are market trend indicators. A tourist's response toward different destinations is described in this study with comparative analysis of Chinese and Pakistani tourists. The study results showed a significantly positive relationship between hotel management professional behavior, customer's loyalty, customer's intimacy and WOM.Research limitations/implicationsThe recruited population might not be represented as the broader and larger visitor population, resulting in restricting establishing tactics. Moreover, this study's results provide significant insight into a tourism industry, hence providing a chance to manage customer loyalty better.Social, managerial and theoretical implicationsThis study contributes significantly to the body of knowledge and provides remarkable insight from the managerial perspective. Interactional justice results in significant value for hotel management directors and top management, front desk staff and operatives and front level employees and managers. Consumer sensitivity of fairness in interpersonal dealings calls for behavioral changes in frontline employees, especially those directly dealing with hotel visitors. Hotel staff and management should formulate a system to deal with the demands and needs of visitors. It should describe the rights and obligations of visitors and ensure that each customer is treated equally and with respect. Customers should be motivated to read the survey questionnaires kept in their rooms and offer their views on the services provided. This strategy might increase the customers' sense of empowerment and leading to notions of fairness in individual encounters.Originality/valueThis study provides an insight into the customer's minds while considering essential variables that include WOM, brand image, perceived service value and uniqueness.

This essay considers what tools should be used to study the legal history of intellectual property. I identify three historiographical strategies: narration, contest, and formation. Narration identifies the diverse “narrative structures” that shape the field of intellectual property history. Contest highlights how the inherent instability of intellectual property as a legal concept prompts recurrent debates over its meaning. Formation recognizes how intellectual property historians can offer insight into broader legal history debates over how to consider the relationship between informal social practices and formalized legal mechanisms. I consider Kara W. Swanson's Banking on the Body: The Market in Blood, Milk and Sperm in Modern America (2014) in light of these historiographical strategies and conclude that Swanson's book guides us to a new conversation in the legal history of intellectual property law.

Introduction. The proposed publication consists of an introduction, texts of two biographical interviews and comments thereon. Both the conversations took place in Elista (2004, 2017) as part of the research project ‘Everyone Has One’s Own Siberia’ dedicated to the important period in the history of Kalmykia though not yet sufficiently explored by anthropologists and sociologists — the deportation of Kalmyks to Siberia (1943–1956) and related memories. Goals. The project seeks to show the daily survival practices of Kalmyks in Siberia. In the spontaneous biographical interviews focusing on the years of Kalmyk deportation, not only the facts cited are important — of which we would otherwise stay unaware but from the oral narratives — but also the introduced stories of inner life: feelings and thoughts of growing girls. Methods. The paper involves the use of textual analysis and the method of text deconstruction. Results. The transcribed texts show survival and adaptation strategies employed by the young generation of ‘special settlers’ in places of forced residence. For many Kalmyks of that generation, high school was a ‘glass ceiling’, a limitation in life choices. In the narrative of R. Ts. Azydova, we face a today unthinkable social package for KUTV students with children — this illustrates how the korenization policy for indigenous populations in the USSR worked, and provides insight into daily practices of pre-war Elista. The story of T. S. Kachanova especially clearly manifests the ‘language of trauma’, first of all, through the memory of the body, vocabulary of death and displays of laughter. The texts of the interviews shall be interesting to all researchers of Kalmyk deportation and the memory of that period.
