Human activities in subterranean environments can affect different ecosystem components, including the resident fauna. Subterranean terrestrial invertebrates are particularly sensitive to environmental change, especially microclimatic variations. For instance, microclimate modifications caused by the visitors may directly affect local fauna in caves opened to the public. However, since numerous factors act synergistically in modulating the distribution and abundance of subterranean species, it remains challenging to differentiate the impact of human intervention from that of other factors. Therefore, evidence of the impact of tourism on cave invertebrate fauna remains scarce. Over a year and with approximately two visits a month, we investigated the effects of the presence of visitors on the subterranean endemic woodlouse Armadillidium lagrecai in the strict natural reserve of Monello Cave (Sicily, Italy). We found that natural microclimatic fluctuations, and not direct human disturbance, were the main factors driving the distribution of A. lagrecai. Specifically, A. lagrecai select for more climatically stable areas of the cave, where the temperature was constantly warm and the relative humidity close to saturation. We also observed a significant temporal effect, with a greater abundance of A. lagrecai in summer and a gradual decrease during the winter months. The number of visitors in the Monello Cave had no effect on the abundance and distribution of A. lagrecai. However, considering the high sensitivity of the species to microclimatic variations, it seems likely that a significant increase in the number of visitors to the cave could indirectly affect this species by altering local microclimate. Constant monitoring of the environmental parameters within the cave is therefore recommended.

This article explores the impact of protests against economic globalization in the public sphere. The focus is on two periodical events targeted by transnational protests: the ministerial conferences of the World Trade Organization (WTO) and the annual meetings of the World Economic Forum (WEF). Based on a selection of seven quality newspapers published in different parts of the world, we trace media attention, support of the activists, as well as the broader public debate on economic globalization. We find that starting with Seattle, protest events received extensive media coverage. Media support of the street activists, especially in the case of the anti-WEF protests, is however rather low. Nevertheless, despite the low levels of support that street protesters received, many of their issues obtain wide public support.

The highly challenging hexaploid wheat (Triticum aestivum) genome is becoming ever more accessible due to the continued development of multiple reference genomes, a factor which aids in the plight to better understand variation in important traits. Although the process of variant calling is relatively straightforward, selection of the best combination of the computational tools for read alignment and variant calling stages of the analysis and efficient filtering of the false variant calls are not always easy tasks. Previous studies have analyzed the impact of methods on the quality metrics in diploid organisms. Given that variant identification in wheat largely relies on accurate mining of exome data, there is a critical need to better understand how different methods affect the analysis of whole exome sequencing (WES) data in polyploid species. This study aims to address this by performing whole exome sequencing of 48 wheat cultivars and assessing the performance of various variant calling pipelines at their suggested settings. The results show that all the pipelines require filtering to eliminate false-positive calls. The high consensus among the reference SNPs called by the best-performing pipelines suggests that filtering provides accurate and reproducible results. This study also provides detailed comparisons for high sensitivity and precision at individual and population levels for the raw and filtered SNP calls.

The article attempts to justify and introduce the scientific term of "political and legal manipulation" that will make it possible to reach a new level of discussion of closely coupled psychological, political and legal means influencing the public consciousness. It is maintained that the term under discussion offers a kind of a methodological stepping stone in the research of the two most important aspects of a far-reaching process of political and legal influence on social processes: a) legal mechanisms, tools, tricks and techniques of carrying out certain political manipulations; b) the impact of political expediency on the law itself, on the processes of lawmaking, implementation and interpretation of law within nations of the world. Political and legal manipulation is viewed as a form of psychological impact on the social relations combining psychological, political and legal means. The article studies in detail the nature, essence and indicators of political and legal manipulation, its main goals and objectives, as well as the selection of tools that lends such a specific character to this kind of manipulation.

With the rise of “sustainable life” activities or lifestyles in the modern era, nowadays people become sensitive and understand about this lifestyle, many things have been developed and started to be done such as minimalist patterns and lifestyles, such as lifestyle to have the goods that are needed and not desired. People start competing to clean their goods by making a full selection of all items in the house and removing items that are not needed, this method is known as “Tidying up” or the art of tidying things. However, this raises various other problems, like the accumulation of household waste that occurs because of the method. Seeing the magnitude of the impact produced by the method, to overcome this problem a thrift shop center is needed in Denpasar and research is carried out using methods that are able to solve the problem, like research that uses structured parameters, like qualitative analysis methods carried out through the process of data analysis from various literatures and interviews with related parties, resulting in a design that accommodates the community to sell or to donate used items to the place of sale of used goods that maintain the value of the goods and places that educate the public that used goods or used clothing basically have high value too.

Aquaria that care for and maintain belugas (Delphinapterus leucas) under professional care have the opportunity to contribute to the conservation of wild belugas through research, expertise in animal care and husbandry, and engaging and educating the public about threats to the species’ health and population sustainability. In an aquarium setting, belugas can be studied under controlled conditions, with known variables that are often difficult to discern when studying wild belugas. Information on nutrition, health status and environmental parameters can be easily obtained in a controlled setting. Biological samples are collected from professionally trained whales that voluntarily participate in informative experimental paradigms. Research studies in aquaria seek to contribute to the recovery and management of endangered beluga populations, such as those in Cook Inlet. Mystic Aquarium’s efforts are presented as a case study. Key research priorities address action items in the Cook Inlet Beluga Recovery Plan and include: (1) understanding the beluga immune system, microbial communities, pathogens and disease; (2) development of non-invasive methods for assessing reproductive status, body condition and health in wild whales; (3) investigation of diving physiology and the impact of altered dive patterns on health; (4) understanding reproduction, a key to recovery and sustainability of wild populations; (5) development and testing of new technologies for tracking and monitoring whales and habitat use; and (6) understanding how noise affects beluga hearing, behaviour and physiology. Expertise in animal handling, behaviour and nutrition contribute to rescue, rehabilitation and capture release efforts. Moreover, ‘students’ of all ages have the opportunity to be engaged, educated and contribute to beluga conservation.

Abstract In this note we explore the effect of the number of daily tests on an epidemics control policy purely based on testing and selective quarantine, and the impact of these actions depending on the time their application starts. Surprisingly, the results not only confirm that increasing the number of tests lowers the number of infected individuals, but also that it has a very beneficial effect limiting the number of quarantined individuals, and thus the socio-economical costs of the epidemics. The results also show that the timing in the application of the measures is as important as the measures themselves. The results suggest that fast decision making and investments to increase testing capabilities are highly rewarded not only from the public health viewpoint, but also from the socio-economical one. The study is carried out in simulation using stochastic cellular automata representing a community of 50'000 individuals. The selection of the tested individuals is carried out based on a contact tracing strategy focused on the closer contacts.

The search for high-affinity aptamers for targets such as proteins, small molecules, or cancer cells remains a formidable endeavor. Systematic Evolution of Ligands by EXponential Enrichment (SELEX) offers an iterative process to discover these aptamers through evolutionary selection of high-affinity candidates from a highly diverse random pool. This randomness dictates an unknown population distribution of fitness parameters, encoded by the binding affinities, toward SELEX targets. Adding to this uncertainty, repeating SELEX under identical conditions may lead to variable outcomes. These uncertainties pose a challenge when tuning selection pressures to isolate high-affinity ligands. Here, we present a stochastic hybrid model that describes the evolutionary selection of aptamers to explore the impact of these unknowns. To our surprise, we find that even single copies of high-affinity ligands in a pool of billions can strongly influence population dynamics, yet their survival is highly dependent on chance. We perform Monte Carlo simulations to explore the impact of environmental parameters, such as the target concentration, on selection efficiency in SELEX and identify strategies to control these uncertainties to ultimately improve the outcome and speed of this time- and resource-intensive process.

Abstract. The Sympson-Hetter (1985) method provides a means of controlling maximum exposure rate of items in Computerized Adaptive Testing. Through a series of simulations, control parameters are set that mark the probability of administration of an item on being selected. This method presents two main problems: it requires a long computation time for calculating the parameters and the maximum exposure rate is slightly above the fixed limit. Van der Linden (2003) presented two alternatives which appear to solve both of the problems. The impact of these methods in the measurement accuracy has not been tested yet. We show how these methods over-restrict the exposure of some highly discriminating items and, thus, the accuracy is decreased. It also shown that, when the desired maximum exposure rate is near the minimum possible value, these methods offer an empirical maximum exposure rate clearly above the goal. A new method, based on the initial estimation of the probability of administration and the probability of selection of the items with the restricted method ( Revuelta & Ponsoda, 1998 ), is presented in this paper. It can be used with the Sympson-Hetter method and with the two van der Linden's methods. This option, when used with Sympson-Hetter, speeds the convergence of the control parameters without decreasing the accuracy.

ABSTRACT Religious traditions in Indonesia are known to be very moderate and tolerant abroad is a reflection of the character of a great noble nation. Between religion, tradition and culture are able to perform compounds so as to create a genuine religious harmony. Because of this reality Indonesia is regarded as the largest Muslim majority country in the world that almost without conflict, in the midst of reality Muslim countries in the Middle East that impressed the dispute into the daily menu. However, the reality of Indonesia as a moderate nation is injured by the act of a group that is fond of terrorism and radicalism by riding Islamic religious teachings. Thus, this reversed religion is assumed as a source of cruelty.   It is through that phenomenon researcher, feel the need to examine the strategy of disseminating moderate Islam by Nahdlatul Ulama. The selection of this Islamic organization according to the authors due to its success in moderating Islam in Indonesia. In this study, the study using a qualitative approach or method as well as adopting the theory of Van Dijk discourse analysis as a scalpel to peel the discourse of moderate Islam published by PWNU East Java through the website. As for this research, the findings are important, among others are: 1) moderate Islamic discourse campaigned by Nahdlatul Ulama East Java is categorized into three segments, namely social, religious and nationality. 2) the text structure that builds moderate Islamic discourse NU East Java in Van Dijk perspective constructed in three domains, namely text, social cognition and social context. 3) the principles of Public Relationship implemented by NU through cyber (online media), among others; News publications and expert opinions, production of image and video-based information, and updating official NU information to the public about their attitudes and views on the phenomena that occur by promoting the values of Islamic moderatism. Key Word : Islamic Moderatism, Nahdlatul Ulama, Cyber Public Relationship

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.
