Law and legislation
Authors: ANTONCHENKO Vadim V.
Published: June 2022

The study is devoted to the analysis of the role of law in the life of modern society and the state and its relationship with the law. In the context of society's search for ways of social evolution, the problem of the relationship between law and legislation is becoming more acute. In this regard, the theoretical issues of the origin of law, its sources, its connection with the state and its role in public relations are of particular importance and acquire great practical importance. Purpose: to form an idea of the true role of legal positivism and its connection with the natural law doctrine in the legal understanding. Methods: historical, historical-legal, concrete-historical, chronological, historical-comparative, historical-typological, hypothetical-deductive, theoretical methods of formal and dialectical logic. Results: the analysis of processes and phenomena related to one or another approach to the understanding of law has shown that the image of law, formed within the framework of concrete historical achievements of society in its material and spiritual development, is characterized by a certain value-cultural attitude to law, which, in turn, has a practical effect on people's lives, the well-being of society and the stability of the state. Conclusions: in a state that proclaims itself democratic and legal, the natural law doctrine of human rights should be the basis for the formation of legislation. The right of freedom, equality and justice, enclosed in the form of a legal norm, is a condition for the harmonious development of society and the stability of the state.
On John Rawls’ theory of justice
Authors: SOLOVYEVA Viktoriya V.
Published: June 2022

The political processes that took place in the world after the Second World War required a new philosophi-cal understanding, since the utilitarian approach, which dominated the Anglo-American political tradition for a long time, could not fully fulfill this task. John Rawls, from whom the revival of political philosophy began, proposed his own version of the solution of the accumulated theoretical problems, which met the social and po-litical demands of his time. Moreover, Rawls was practically the first to put justice at the center of political and philosophical thought. The problem of justice has been the subject of attention of philosophers since Antiquity, however, the doctrine of justice was the components of social and moral teachings in general, while traditionally the main issue for political philosophy was the question of power, its political organization and legitimacy. The purpose of the article is a scientific analysis of the political and philosophical legacy of John Rawls. Rawls dem-onstrated that the political organization of power is derived from how we understand ethical norms and what norms (rules) we are guided by in social interaction, therefore the main issue of political philosophy is not the question of power, but the question of justice. In addition, he was convinced that political freedom is closely re-lated to equality. The methodological basis included the dialectical method, a group of general scientific methods of cognition – the method of analysis and synthesis, the structural method, as well as private scientific ones - formal legal and comparative legal methods. It is concluded that Rawls’ theory of justice had a decisive influence on the political philosophy of the twentieth century, the development of which largely took place on the basis of criticism or reception of his ideas. Today we are witnessing the beginning of a break with the tradition of which Rawls is the spokesman and which assumes that the political is based on the possibility of consensus and ethical agreement. However, the current development of political philosophy is also closely related to the rethinking of Rawls’ legacy, which we see, in particular, in the development of so-called “imperfect” political theories.
Comparative legal analysis of the institute of movement without convoy in the countries of the Commonwealth of Independent States
Authors: CHEREMIN Nikita V.
Published: June 2022

In the light of the planned course of development of the penal enforcement system (the adoption of a new development concept until 2030, which, in turn, implies the creation of a joint type of institution), the develop-ment of the institution of movement of convicts without escort or escort becomes an urgent issue. From the standpoint of identifying positive foreign experience, the study of the development of this institution in the countries of the Commonwealth of Independent States is of scientific interest, since the legal system of these countries (legal system, legal culture, legal realization) is closest to the legal system of our country. In the course of studying this institute, the author comes to the conclusion that, despite the commonality of the legal systems of the Russian Federation and the former republics of the Soviet Union, the norms governing the institution of movement without escort in these countries have received different levels of development. The main research tool was the comparative legal method. With the help of it, the general and special features of this institution were identified in the legislation of the countries studied. Based on the data obtained, the author suggests consi-dering the possibility of making the following amendments to Article 96 of the Criminal Executive Code of the Russian Federation: remove the ban on the withdrawal of HIV-infected convicts to BP; establish other deadlines for withdrawal to BP in order to study the convict's personality in more detail; to establish that the right to travel without escort or escort outside the IU is granted to the convicted person by the decision of the head of the IU, agreed with the prosecutor overseeing the enforcement of legality in the IU; to establish a ban on the withdrawal of convicts who were previously deprived of the right to BP for any offense committed.

Published: June 2022

The paper describes the results of research of icicles formation and growth on wire nozzles when water is sprinkling with a striking on a hard surface and (or) use a nozzle for spraying water at ambient temperatures of outside air -3 ... -7 °C. The studies were carried out on wires with a diameter of 3 mm and 0.5 mm with a distance between the nozzles of 10 mm and 29 mm, respectively. Dependences of the ice mass calculating, assigned to one meter of the nozzle and the temperature difference in 1 °C on time, were obtained. The icicles growth process on horizontal nozzles in time has been studied. Values of the growth rate were obtained: in the direction of the radius was 0.3 mm per 1 °C and the elongation rate was about 1 mm per hour at an ambient temperature of -5 °C. The maximum length of icicles depends on the distance between the nozzles. The free section for air flowing is blocked by ice after a while, and the water supply to the icicles is blocked. The required distances between the parallel nozzles are calculated for different air temperatures. Distances between the parallel nozzles have to be extended for increasing section for air flowing if water crystallization heat is used for ventilation systems or heat pumps.

The average thermal power of the installation with wire horizontal nozzles, which can be used to heat the air by the heat of water crystallization, has been determined. The average thermal power increases over time, which is associated with increasing heat exchange surface and part of the formed ice from the water that has fallen on the surface of the packing. For the first 30 min. of work, the average value of the share of formed ice is 8%. After 7 hours. work, up to 28% of the water falling on the nozzles turns into ice. From 1 to 4 kW of average thermal power can be got at air temperatures of –5…-10 ° С of the area from 1 m2 of ​​the nozzles. The specified air heater does not require significant investment, consumes a minimum amount of electricity, does not require human labor to remove the finished product, and can be mechanized and automated. To increase the number of nozzles without the growth of adjacent rows, it is proposed to place the nozzles in a checkerboard pattern

Published: June 2022

The purpose of the study in this paper is based on a detailed analysis of various mathematical and statistical methods for determining the similarity and uniformity of daily schedules of electrical load to form an approach to solving several important tasks. Namely, method of forming a static sample of complex load measurement data for the same included composition of single electrical receivers, selection of the optimum declared schedule of electric loading at purchase of the electric power on "Energorinka", as well as solving other similar tasks, all this in general requires effective clustering of graphs.

Due to the fact that daily schedules of electrical load are divided into working days, pre-weekend, pre-holiday and weekend in this paper it is proposed to express the data of electric load graphs in Cartesian or polar coordinates. This allowed us to record the difference between the daily schedule of electrical load on normal working days from the day before.

The efficiency of application of these methods of search of identical and similar daily schedules of electric loading was analyzed by allocation of several basic types of similarity of time series, similar: in time, on the form, on structure.

It is shown that the calculation of the Euclidean distance allows to determine the uniformity of daily load graphs. And phase analysis is their similarity. The most acceptable method is to determine the correlation coefficient, which reveals the similarity and similarity of daily schedules of electrical load.

The provision of increasing the level of safety of the power plant in case of emergency shutdown, as well as increasing the efficiency of the boiler is considered. Disconnection of CHP from the grid entails, first of all, the threat of cessation of heat water supply to the city and, as a consequence, human and material losses. One of the options to prevent or minimize the consequences of such an accident at municipal CHPs, which is a system of rapid power recovery of the power plant regardless of external circumstances by installing a condensing heat exchanger and turbine on the organic cycle Rankin. Such a turbine can serve as a start-up power source for the station, and work together with a steam turbine, increasing the efficiency of the unit as a whole. This system is universal for units running on natural gas.
Principles of vineyard establishment and strategies to delay ripening under a warming climate

Published: June 2022

Some viticultural strategies may offer a natural solution to mitigate the negative effects of global warming in viticulture. Decisions concerning vineyard topography variables, as well as rootstock, variety, clone, training system, and row orientation and slope selection may be combined. This allows to delay grape maturation on certain days when they are applied separately and on a few weeks if they are applied together. They can be applied to new vineyards but also to existing vineyards, as for most premium wine producers worldwide it isn't an option to replant somewhere else.
Legacy of land-cover changes on soil microbiology in Burgundy vineyards (Pernand-Vergelesses, France)

Published: June 2022

Present-day soil physicochemical characteristics, land use/land cover (LULC), and field management practices are commonly recognised as the main drivers shaping archaeal/bacterial and fungal communities in vineyard soils. Few studies have investigated the legacy of past land uses on soil microbial biodiversity, yet anthropogenic disturbances have already been proven to affect soil characteristics over decades. In this study, we explore the possibility of long-lasting impacts of forest-to-vineyard conversion on present-day soil archaeal/bacterial and fungal communities after 15 years of vine cultivation.The selected study area is in a Burgundian vineyard (Pernand-Vergelesses, Burgundy, France), where it was possible to reconstruct the history of land cover and land use for the past 40 years. Soil samples were collected from five zones managed under similar pedo-climatic conditions but with different land-use histories (a 70-year-old vineyard, a 15-year-old vineyard converted from pine forest, a 15-year-old vineyard converted from mixed forest, a pine forest and a mixed forest). For each zone, basic physicochemical parameters (organic carbon, total nitrogen, copper, C:N ratio, and soil texture) were measured, and DNA was extracted to characterise the microbial biomass, and also the richness and taxonomic composition of archaeal/bacterial and fungal communities (16S and 18S).Our results show that changes in LULC lead to differential responses in soil microbial biomass, and in archaeal/bacterial and fungal richness and taxonomic composition. After 15 years of cultivation, the present-day microbial biomass and indigenous archaeal/bacterial communities of recent vineyard soils are shown to be partly inherited from past LULC, but no evidence was found of long-term impacts of past land use on fungal communities. Past land-use history should therefore be added to the well-established set of environmental drivers, providing valuable information to explain the spatial variability of soil microbiology, observed at intra-plot, plot, and landscape scales. Integrating the history of changes in LULC is therefore recommended to evaluate and adopt the best strategies to develop sustainable management practices.
Variety-specific response of bulk stomatal conductance of grapevine canopies to changes in net radiation, atmospheric demand, and drought stress.

Published: June 2022

In wine growing regions around the world, climate change has the potential to affect vine transpiration and overall vineyard water use due to related changes in daily atmospheric conditions and soil water deficits. Grapevines control their transpiration in response to such changes by regulating conductance of water through the soil-plant-atmosphere continuum. The response of bulk stomatal conductance, the vine canopy equivalent of stomatal conductance, to such changes were studied on Cabernet-Sauvignon, Merlot, Tempranillo, Ugni blanc, and Semillon vines in a non-irrigated vineyard in Bordeaux France. Whole-vine sap flow, temperature and humidity in the vine canopy, and net radiation absorbed by the vine canopy were measured on 15-minute intervals from early July through mid-September 2020, together with periodic measurements of leaf area, canopy porosity, and predawn leaf water potential. From these data, bulk stomatal conductance was calculated on 15-minute intervals, and multiple linear regression analysis was performed to identify key variables and their relative effect on conductance. For the regression analysis, attention was focused on addressing non-linearity and collinearity in the explanatory variables and developing a model that was readily interpretable.Variability of vapour pressure deficit in the vine canopy over the day and predawn water potential over the season explained much of the variability in bulk stomatal conductance overall, with relative differences between varieties appearing to be driven in large part by differences in conductance response to predawn water potential between the varieties. Transpiration simulations based on the regression equations found similar differences between varieties in terms of daily and seasonal transpiration. These simulations also compared well with those from an accepted vineyard water balance model, although there appeared to be differences between the two approaches in the rate at which conductance, and hence transpiration is reduced as a function of decreasing soil water content (i.e., increasing water deficit stress). By better characterizing the response of bulk stomatal conductance, the dynamics of vine transpiration can be better parameterized in vineyard water use modeling of current and future climate scenarios.
Grapevine recovery after fire and a first look at rapid damage assessment with satellite imagery

Published: June 2022

There is increasing scientific consensus that climate change is one of the underlying causes of the prolonged dry and hot conditions that have increased the risk of extreme fire weather inmany countries around the world. In December 2019, a bushfire occurred in the Adelaide Hills, South Australia, where 25,000 hectares were burnt, and in vineyards and surrounding areas various degrees of scorching and infrastructure damage occurred. The ability to coordinate and plan recovery after a fire event relies on robust and timely data. The current practice for measuring the scale and distribution of fire damage is to walk or drive the vineyard and score individual vines based on visual observation. The process is time consuming, subjective, or semi-quantitative at best. After the December 2019 fires, it took many months to access properties and estimate the area of vineyard damaged. This study compares the rapid assessment and mapping of fire damage using high-resolution satellite imagery with more traditional ground-based measures. Correlations between ground visual fire damage assessments and postfire NDVI (-­0.347 to -0.084) and VARIgreen (-0.333 to 0.074) satellite imagery were significant but showed no correlation to a weak negative correlation. Canopy growth, vine fertility and starch concentrations were tracked in the two seasons following the fire event to assess vine recovery. Canopy health in the seasons following the fires correlated to the severity of the initial fire damage. Severely damaged vines had reduced canopy growth, were infertile or had very low fertility as well as lower starch concentrations in buds and canes during dormancy, which reduced productivity in the seasons following the bushfire event. In contrast, vines that received minor-moderate damage were able to recover within 1-2 years. Tools that rapidly and affordably capture the extent and severity of damage over large vineyard area will allow producers, government and industry bodies to manage decisions in relation to fire recovery planning, coordination and delivery, improving the efficiency and effectiveness of their response.
Terroir analysis and its complexity
Authors: Bonfante Antonello , Brillante Luca
Published: June 2022

Terroir is not just a geographical site, but also a complex concept aiming to express the “collective knowledge of the interactions” between the environment and the vines mediated through human action, “providing distinctive characteristics” to the final product (OIV 2010).In the popular press, it is often treated and communicated without a proper understanding of the mechanistic relationships between the wine characteristics and the site. These relationships are primarily rooted in the physical environment, particularly in the interactions between the soil-plant and atmosphere system, affecting grapevine physiology, grape composition and wine. Comprehension of the phenomena starts with viticulture zoning techniques, a crucial first step in mapping, describing and further studying terroirs. Viticulture zoning can be carried out with diverse empiricism and expertise and achieving different level of details in describing complex biophysical processes. Spatial and temporal scales can vary across studies, and not all of them have been able to capture the multidisciplinary nature of the terroir.The scientific understanding of the mechanisms ruling vineyard variability and grape composition is one of the most critical scientific focuses of terroir research. This knowledge can contribute to the analysis of climate change impacts on terroir resilience, the identification of new suitable land for viticulture, and the precise management of vineyards to reach a specific oenological goal.This article gives an overview of the latest approaches to terroir studies and of new zoning technology, with particular attention to their importance in supporting terroir resilience to climate change.

The proposed study is theoretically significant to some degree for methodological science (the section devoted to communicative competence and its components) and is practically valuable since it describes the specific experience of the formation and development of the competence being studied in higher education.
Contesting space and power: Rethinking Habermas’s public sphere on the Madurese paternalistic ideology
Authors: Budiyanti Syamsu , M. Siahaan Hotman , Nugroho Kris
Published: June 2022

The public sphere is not always what Jürgen Habermas imagines, which is inclusive, egalitarian and pressure-free. In the Madurese paternalistic constellation, the dominations of power over the contestation of public opinion and action become prominent in the relationship between participants/actors. A meeting between different interests causes this contestation. The struggle for influence is also shown by the dominance of ‘capital’ or resources. In Madura, Kiai are considered to have ‘charismatic’ symbolic capital related to the historical and cultural aspects of the Madurese ethnicity. This makes the figure of Kiai (along with Blater as a twin regime) become the center of consensus-making in a paternalistic public discussion. This phenomenological qualitative research becomes interesting when the world view of the local community is connected with Habermas’ perspective through the idea of European version of the bourgeois public sphere, which is considered not applicable to the local genius Madurese realm. The arena of public sphere in the Tanean Lanjhang pattern and the existence of ‘langgar’ (mosque) in the social community rejects the characterization of Habermas and brings a new definition of Madurese paternalistic public sphere, which is hegemony-mutualistic, as one of the richness of Indonesian cultural patterns.

Published: June 2022

Television, with a larger audience than other mass media in Indonesia, can improve youth engagement in politics, or at least their curiosity about politics. Previous studies showed inconclusive results concerning the effects of television viewing and political interest. However, the current study assessed the effect of talk shows and variety show viewership on college students’ political interests. A survey was conducted of 400 college students at Universitas Pembangunan Nasional Veteran Jakarta (UPNVJ), Jakarta, Indonesia, using a stratified sampling technique and data analysis with multiple linear regression analysis. The results verified that talk shows and variety show viewership directly relate to the political interest in youth. Variety show viewership has a negative relationship, which means that political interest decreases as viewing of variety show increases. Television use, talk show viewership, and political knowledge positively correlate with political interest. The author suggests a sample from a broader geographical area in the future. Furthermore, the conceptualization of variety shows should be examined more.

However, over the past year and a half, similar to all other countries in the world, the educational conditions of Sri Lanka have also been affected by the unexpected circumstances of Covid-19 pandemic. However, the Sri Lankan government has taken various initiatives to ensure the educational activities. In this regard, this study aims to determine the impacts of current home-based educational activities on low-income families in Sri Lanka. Qualitative research method was used in this study, 90 low-income families were selected as the study sample. In-depth interview technique and observation were used to collect data and thematic analysis method was used for data analysis. As a result of this study, most of the students from low-income families are unable to engage in the online learning process at home, learning activities of children have become a burden to the parents and parents temporarily abstain their children from learning in some families. Therefore, the study recommends that the government should concentrate to facilitate the children in such low-income families to continue their learning in a non-burden and cost-efficiency manner during the pandemic situations.

Throughout history, activism has evolved with the rise of digital technologies. Individuals and groups can now conduct political activities on social media platforms. Existing studies about hashtag activism typically centered on race and gender, which are usually contextualized in the West. This study addresses the insufficient research about online activism related to policymaking in the Philippine context and focuses on online activism towards the issue of the Anti-Terrorism Bill (ATB) of 2020 that concerns potential harm to freedom of speech, expression, or of the press. This research was inspired by George and Leidner’s (2019) Hierarchy of Digital Activism, notably the Digital Spectator activism. The researchers utilized data mining approach to collect data sets scraped from Twitter. The data was acquired by using TWINT and extracting Twitter’s visible measure of interaction such as likes, retweets, and replies. These data were used to analyze Twitter users’ online activism during the heightened discussion of ATB that showed negative views of the bill using the topmost hashtag, #junkterrorbillnow and the five dominant themes: law-making process, human security, the role of social media, dialogue, and related issues. Findings also showed a link between #junkterrorbillnow and the dominant themes, and the digital spectator activities.
Early Ediacaran and Middle Ediacaran Granitoids in the Provenances of Early Cambrian Coarse-Grained Rocks of the Bayan-Kol Formation of the Systyg-Khem Depression (Tuva)

Published: June 2022

—The Tuva segment of the Central Asian Orogenic Belt is characterized by the ubiquitous presence of conglomerates few tens of meters to a kilometer in thickness in early Paleozoic volcanosedimentary sequences. We present the first results of geochemical, isotopegeochemical (Sm–Nd and Rb–Sr), and U–Pb geochronological studies of granitoid boulders and pebbles from the conglomerate sequence of the early Cambrian Bayan-Kol Formation of the Systyg-Khem depression. These studies made it possible to establish several sources of clastic material as a result of the destruction of granitoids of different ages and isotope-geochemical compositions. At least two complexes of granitoids were denuded in the pre-Ediacaran tectonic block in the early Cambrian: (1) middle Ediacaran (~590 Ma) and (2) early Ediacaran (~630 Ma); the latter resulted from the melting of pre-Ediacaran island arc crust formed from a depleted mantle source (εNd(T) = +8.0 to +8.6). At present, no granitoids of this age and with such isotope-geochemical characteristics have been found within the Tuva segment. Probably, the granitoid complexes reconstructed from the results of study of clastic conglomerates are eroded or buried beneath younger deposits and do not expose. Thus, the study of clastic conglomerates from the Bayan-Kol Formation provided the first information about the Precambrian history of the tectonic block whose destruction led to the accumulation of this terrigenous sequence.

Background: The prevalence of overweight (15%) and obesity (6%) in children under five years of age in Canada are high, and young children with overweight and obesity are at increased risk of the development of chronic disease(s) in adulthood. Prior research has demonstrated very few published trials on effective obesity prevention interventions in young children at risk of obesity, within primary health care settings. The aim of this study is to determine if 18 - 48-month-old children at risk for obesity, who are randomized to receive the Parents Together program (i.e., intervention group) have reduced body mass index z-score (zBMI), compared to those not receiving the intervention, at 12-month follow up. Secondary clinical outcomes between the intervention and control groups will be compared at 12 months.Methods: A pragmatic, parallel group, 1:1, superiority, randomized control trial (RCT) through the TARGetKids! Practice Based Research Network will be conducted. Young children (ages 18 – 48 months) who are at increased risk for childhood obesity will be invited to participate. Parents who are enrolled in the intervention group will participate in eight weekly group sessions and 4 – 5 coaching visits , facilitated by a trained public health nurse. Children and parents who are enrolled in the control group will receive usual health care. The primary outcome will be compared between intervention arms using an analysis of covariance (ANCOVA). Feasibility and acceptability will be assessed by parent focus group and interviews, and fidelity to the intervention will be measured using nurse completed checklists. A cost-effectiveness analysis (CEA) will be conducted. Discussion: This study will aim to reﬂect the social, cultural, and geographic diversity of children in primary care in Toronto, Ontario represented by an innovative collaboration among applied child health researchers, community health researchers, and primary care providers (i.e., paediatricians and family physicians in three diﬀerent models of primary care). Clinical and implementation outcomes will be used to inform future research to test this intervention in a larger number, and diverse practices across diverse geographic settings in Ontario.Trial registration: Date of registration: June 27th, 2017; Registry: ClinicalTrials.gov; Registration number: NCT03219697

This paper deals with the problem of estimating the parameters of heavy-tailed sea-clutter in high-resolution radar, when the clutter is modelled by the correlated Pareto type II distribution. Existing estimators based on the maximum likelihood (ML) approach, integer-order moments (IOM) approach, fractional-order moments (FOM), and log-moments (log-MoM) have shown to be sensitive to changes in data correlation. In this work, we resort to a deep learning (DL) approach based on a multi-headed architecture to overcome this problem. Off-line training of the artificial neural networks (ANN) is carried out by using several combinations of the clutter parameters, with different correlation degrees. To assess the performance of the proposed estimator, we resort to Monte Carlo simulation and we observed that it has superior performance over existing approaches in terms of estimation mean square error (MSE) and robustness to changes of the clutter correlation coefficient.

Background: Up to 30% of the European population lives in an European internal border region. In the Meuse-Rhine Euroregion (EMR) multiple challenges on pandemic response were brought to the attention early on in the COVID-19 pandemic. Citizens and border commuters in the EMR were confronted with difficulties related to divergent policies applicable in the three nations. A thorough analysis of the pandemic response in Euroregions through comparable cross-border data collection enables the evaluation of different infection prevention policies on public health. Methods: ‘Impact of COVID-19 on the EMR’ is a longitudinal study of SARS-CoV-2 antibodies in inhabitants of the EMR. The sampling design is stratified random sampling. Prospective data collection took place between April and November 2021, and consisted of two self-finger prick antibody tests and two online questionnaires. The study enables to evaluate (1) the prevalence of anti-SARS-CoV-2 antibodies and its determinants and (2) the practice and attitudes to COVID-19 measures on the population in the EMR over time. Discussion: The project is a unique example of a close interregional cooperation in the development of a shared research project; conceptual development, survey-approach, data-collection, data-analysis and reporting. Collection of comparative cross-border data can aid policy makers, health care providers and other stakeholders to better assess the impact of infectious disease control measures in border regions.

Islands are key areas for biodiversity; however, they are extremely sensitive to anthropic actions. This has led to local species extinctions, especially large predators such as raptors. Consequently, reintroduction and conservation projects aimed at reversing population decline of endangered species have recently gained popularity. Nevertheless, their relatively elevated cost and chance of failure make them controversial, hence assessing their effectiveness is essential. Within the early stages of raptors, the post-fledging dependency period (PFDP) is the one in which individuals must face dangers without having completely developed their skills. Thereby, comparing PFDP patterns concerning reintroduced and wild individuals is of major interest as it would help to plan and improve future conservation actions. We analyzed the behavior of 38 juvenile Bonelli’s eagles (15 reintroduced and 23 wild) tracked through GPS telemetry, tagged as nestlings in two insular environments. The study period encompassed a total of nine-year movement data from reintroduced chicks in Mallorca (Spain) and wild chicks from Sicily (Italy). Movement parameters (i.e., age of first flight, age of dispersal, length of the PFDP, revisits to the natal or release area, and residence time in them) were analyzed together with their behavior during the PFDP for reintroduced and wild individuals. Similar movement patterns were obtained for both origins, although wild individuals revisited the natal site more often and dispersed earlier. Behavior was also similar, it varied throughout the PFDP, observing a more abrupt progress in wild individuals and an earlier development of travelling and hunting behaviors. Observed differences are probably related to food availability, which can improve body condition and thus delay onset of dispersal, together with parental presence, which can prompt an earlier ending of the PFDP by encouraging juvenile independence.

Smart farming is becoming the need of the hour nowadays in an effort to boost productivity and protect the crops. This can be done using sensors and internet enabled devices in the farm. The underlying wireless sensor network can sense various environmental parameters and can pass data to the internet enabled devices to support smart farming. The sensor nodes are, however, powered by smaller batteries and have limited lifetime. Therefore, this paper presents a clustering protocol which aims at increasing the lifetime of the sensor nodes. These sensors are considered to be pressure sensors which are deployed in the network and whenever any animal encroaches the farm, a signal can be passed to the internet enabled alarm system which can help the farmer to fend off the animals and protect his crops. The sensor network is considered to have three level of energy heterogeneity among the nodes and the cluster head is selected in such a way that the cluster formed by the head consists of more number of high energy nodes. The proposed protocol has been simulated in MATLAB environment and compared with SEP, DEEC and ISEP based on network lifetime and throughput. The protocol has shown better performance against these existing protocols.
