Identification and Expression Profile of Chemosensory Receptor Genes in Aromia bungii (Faldermann) Antennal Transcriptome

The red-necked longicorn beetle, Aromia bungii (Faldermann) (Coleoptera: Cerambycidae), is a major destructive, wood-boring pest, which is widespread throughout the world. The sex pheromone of A. bungii was reported earlier; however, the chemosensory mechanism of the beetle remains almost unknown. In this study, 45 AbunORs, 6 AbunGRs and 2 AbunIRs were identified among 42,197 unigenes derived from the antennal transcriptome bioinformatic analysis of A. bungii adults. The sequence of putative Orco (AbunOR25) found in this study is highly conserved with the known Orcos from other Coleoptera species, and these Orco genes might be potentially used as target genes for the future development of novel and effective control strategies. Tissue expression analysis showed that 29 AbunOR genes were highly expressed in antennae, especially in the antennae of females, which was consistent with the idea that females might express more pheromone receptors for sensing pheromones, especially the sex pheromones produced by males. AbunOR5, 29, 31 and 37 were clustered with the pheromone receptors of the cerambycid Megacyllene caryae, suggesting that they might be putative pheromone receptors of A. bungii. All six AbunGRs were highly expressed in the mouthparts, indicating that these GRs may be involved in the taste perception process. Both AbunIRs were shown to be female-mouthparts-biased, suggesting that they might also be related to the tasting processes. Our study provides some basic information towards a deeper understanding of the chemosensing mechanism of A. bungii at a molecular level.

Analisis Video Comments to Video Views Ratio Youtube Pada 8 Rekomendasi iPhone Terbaik 2021

ABSTRACTThis study focuses on consumer interest in the 8 best iPhone recommendations in 2021. Smartphone products issued by Apple Inc., which include the dimensions of the best iPhone. In this study, the smartphone product is not only seen as a product but also a brand, so that consumer interest becomes important in shaping the smartphone brand image. iPhone is a smartphone product that was first developed by the leader of the Apple Computer company, Steven Paul Jobs. a leader with a name identical to himself. This research uses qualitative research with descriptive research type. This research method is a case study of the best recommended iPhone 8 product in 2021. In collecting data, the researchers conducted an analysis of video comments to video views on youtube. Some of the theories used in this study include the dimensions of the smartphone brand, consumer interest, and several other relevant theories. Based on the results of the analysis, the researchers found that each informant had various perceptions of the dimensions of the smartphone brand as seen from the attributes of Apple products. Differences in perception occur because of differences in experience and background interests, habits, and other things from the informants who play a role in this perception process. Even so, the perception of informants who are iPhone consumers does not necessarily show the image of the iPhone product as a whole, because this study does not aim to generalize consumer perceptions.

A Review of Risk Perception in Construction Industry

The construction industry has been notorious for its high rates of accidents and injuries associated with social, financial, and legal implications. Previous studies mention that risk perception is related to workers´ safety behavior and, therefore, accidents. This review aims to identify in which context risk perception has been studied in recent years and the variables associated with it. Google Scholar and Science Direct databases were searched for articles using the following keywords: “risk perception,” “construction industry”, and “safety behavior.” The inclusion criteria were that the articles answered the questions formulated in the spider methodology. Sixty-three articles were included in the literature review. The results indicated that risk perception is a subjective judgment that results from the combination of the likelihood perception of a specific risk being present and the severity perception of the risk if it occurs. The risk perception has been studied in different areas such as tourism, driving behavior, electricians, firefighters, and confrontation to viruses or pandemic, and the construction industry. Personal traits, sociodemographic variables, cultural factors, and occupational characteristics (training in security, experience, and seniority at work) have been addressed to study risk perception in construction workers. Safety must be a priority for construction organizations. This study highlights the importance of studying risk perception in the workplace since construction workers are exposed to risky activities at work. Also, it is important to understand the risk perception process and its contributory factors for construction workers. It is possible to have specific information that helps design actions for effective risk management and prevent the number of accidents and fatalities from increasing.

Visual Perception and Understanding of Variable Message Signs: The Influence of the Drivers’ Age and Message Layout

Variable message signs (VMS) are used to display messages providing up-to-date traffic-relevant information so that drivers can safely adapt their behavior in real time. The information reported in a VMS should be brief but comprehensive to minimize perception time. The latter can be influenced by the way the message is displayed. This study investigates how the different ways of displaying the same message can influence reading time and the information perception process at different driving speeds. Specifically, the following message characteristics are investigated: (i) use of uppercase and lowercase letters; (ii) use of familiar pictograms; and (iii) use of less familiar pictograms. Furthermore, as perception time typically changes with ageing, drivers belonging to three different age classes are tested. The experimentation was performed by simulating a vehicle passing along a straight road upon which a VMS displaying different messages was placed. Experimentation results are analyzed using the Kruskal–Wallis test, Friedman rank-sum test and Welch one-way ANOVA, showing that: (i) the use of uppercase or lowercase does not seem to significantly affect reading times; (ii) the use of pictograms that are not very familiar to habitual road-users can be counterproductive for the perception process; (iii) elderly drivers always have greater difficulty in perceiving the message than young or middle-aged drivers. The findings of this study can be of help for traffic authorities to design the most suitable structure for a VMS so that its information can be unequivocally and immediately conveyed to drivers.

ANALYSIS OF THE PSYCHOLOGICAL CHARACTERISTICS OF THE PERCEPTION OF YOUNGER SCHOOLCHILDREN IN THE CONTEXT OFTEACHING THE RUSSIAN LANGUAGE

The article is devoted to the analysis of the peculiarities of perception and the specifics of the course of the perception process in a younger student. Effective methods for enriching his vocabulary are described. It is concluded that vocabulary work is the leading direction in the development of a child's speech activity and requires a high level of professionalism and certain pedagogical efforts from the teacher.

Linguistic and cultural connotations of the lexeme BIRCH in Russian and the lexeme BAMBOO in Chinese

The paper studies the historical and cultural associative meanings of the lexeme BIRCH in the Russian culture and the lexeme BAMBOO in Chinese by analyzing the results of the perception process of these objects, their concepts and images by native speakers of the Russian and Chinese languages. The relevance of the research is due to the growing attention of modern linguistics to comparative cultural studies, including the number of comparative works on the Russian and Chinese languages, the importance of describing linguistic and cultural differences for the development of international economic and cultural relations between China and Russia. The research material involves phraseological units, proverbs, myths, poems and literary works, as well as historical materials, customs and traditions of the two nations. This paper uses research methods such as descriptive, contextual, comparative, the method of component analysis and cognitive modeling. As a result, it was determined that birch occupies a significant place in the Russian culture with the meanings of “motherland”, “mother”, “woman”, “bride”, “girl”. Bamboo in Chinese has only positive connotations, including “unshakable quality”, “spiritual purity”, “humble character”, “high aspirations.” It is concluded that birch as a symbol of Russia is a lacunar concept in the Chinese culture, while bamboo as the personification of a “perfect gentleman” in Chinese has no cultural connotation in Russian. Despite mismatched meanings in two languages, birch and bamboo must be recognized as equivalents in terms of cultural significance and the high frequency of symbolic use in poetry and other precedent texts.

Evaluation of the Hazard Perception Skills of Young Drivers

The aim of this study is to collate valuable information about the hazard perception process of (young) drivers and to evaluate their hazard perception skills. For this, an eye-tracking system was used to record the visual behaviour of drivers. In addition, a system based on a data logger and sensors was developed to capture and log the relevant data from the vehicle. By tapping into the vehiclés CAN bus (Controller Area Network), the needed parameters (e.g. position of accelerator, brake, and clutch pedal, as well as the steering wheel angle) were acquired through the reverse engineering of the vehicle′s CAN stream. All the captured data was subsequently synchronized and overlaid in the eye-tracking video. The complete system, i.e. data-logger and sensors, was consistently integrated into a driving school car. Due to the fact that all the data was captured in real-time whilst driving in traffic, every analysed situation can be considered unique and therefore cannot be compared to other situations. The results of the study revealed that only in 18% of the analysed situations, the hazard-perception skills were adequate or the same as they were taught at the driving school just a few months previous. Confronted by the videos of their lessons, the participating drivers adjusted their self-assessment scores for their driving skills downwards by around 25% on average.

Moving in synchrony with an avatar – presenting a novel and unbiased body sway synchronization paradigm

Moving in synchrony with one another is a fundamental mechanism that maintains human social bonds. Yet, not all individuals are equally likely to coordinate their behaviors with others. The degree of interpersonal coordination is greatly influenced by pre-existing characteristics of the interacting partners, like the cultural homogeneity of a group, shared goals, and the likability of the other person. Considering that most research questions necessitate an experimental set-up without such uncontrolled biases, we created a novel, unbiased paradigm: a human-avatar body sway synchronization paradigm. Participants’ body sway was measured by a force plate while being exposed to a medio-laterally moving avatar. Forty-nine participants were tested in a social condition (motionless vs. moving avatar) and a non-social control condition (motionless vs. moving column). The results revealed that participants increased their body sway on their medio-lateral axis while the avatar was moving. The participants did not increase their body sway in the non-social control condition, indicating that the participant’s movement was not simply caused by a basal motion perception process. The current study builds a methodological fundament that can help to reduce biases due to pre-existing rapport between interaction partners and serves as a valuable experimental paradigm for future synchrony studies.
