Authors: Aviles Jessica , Porter Gwenndolyn C. , Estabrooks Paul A. , Alexander Neil B. , Madigan Michael L.
Published: March 2020

Purpose

The purpose of the study was to evaluate the feasibility of implementing reactive balance training (RBT) in continuing care retirement communities, as a part of typical practice in these facilities.

Methods

RBT, a task-specific exercise program, consisted of repeatedly exposing participants to trip-like perturbations on a modified treadmill to improve reactive balance and subsequently reduce fall risk. Semistructured interviews were conducted with retirement community residents (RBT participants) and administrators, to assess the organizational context, perceptions of evidence for falls prevention, and facilitation strategies that could improve the likelihood of implementing RBT as a falls prevention program.

Results

Contextual factors such as leadership support, culture of change, evaluation capabilities, and receptivity to RBT among administrators and health leaders at the participating retirement communities could facilitate future implementation. The cost associated with RBT (e.g., equipment and personnel), resident recruitment, and accessibility of RBT for many residents were identified as primary barriers related to the intervention. Participants perceived observable health benefits after completing RBT, and had increased awareness toward tripping and greater confidence with respect to mobility. Across interviewees, potential barriers for implementation regarding facilitation revolved around the compatibility and customizability for different participant capabilities that would need to be considered before adopting RBT.

Conclusion

RBT could fill a need in retirement communities, and the findings provide areas of context, characteristics of the intervention, and facilitation approaches that could improve uptake.
Measuring Information Preferences
Authors: Ho Emily H. , Hagmann David , Loewenstein George
Published: March 2020

Advances in medical testing and widespread access to the internet have made it easier than ever to obtain information. Yet, when it comes to some of the most important decisions in life, people often choose to remain ignorant for a variety of psychological and economic reasons. We design and validate an information preferences scale to measure an individual’s desire to obtain or avoid information that may be unpleasant but could improve future decisions. The scale measures information preferences in three domains that are psychologically and materially consequential: consumer finance, personal characteristics, and health. In three studies incorporating responses from over 2,300 individuals, we present tests of the scale’s reliability and validity. We show that the scale predicts a real decision to obtain (or avoid) information in each of the domains as well as decisions from out-of-sample, unrelated domains. Across settings, many respondents prefer to remain in a state of active ignorance even when information is freely available. Moreover, we find that information preferences are a stable trait but that an individual’s preference for information can differ across domains.

An Achievable-Region-Based Approach for Kidney Allocation Policy Design with Endogenous Patient Choice
Authors: Ata Baris , Ding Yichuan , Zenios Stefanos
Published: March 2020

Problem definition: Deceased-donor kidney transplant candidates in the United States are ranked according to characteristics of both the donor and the recipient. We seek the ranking policy that optimizes the efficiency–equity tradeoff among all such policies, taking into account patients’ strategic choices. Academic/practical relevance: Our approach considers a broad class of ranking policies, which provides approximations to the previously and currently used policies in practice. It also subsumes other policies proposed in the literature previously. As such, it facilitates a unified way of characterizing good policies. Methodology: We use a fluid model to approximate the transplant waitlist. Modeling patients as rational decision makers, we compute the resulting equilibria under a broad class of ranking policies, namely the achievable region. We then develop an algorithm that optimizes the system performance over the achievable region. Results: We show analytically that it suffices to restrict attention to priority scores that are affine in the patient’s waiting time. We also show through a numerical study that the total quality-adjusted life-years can be increased substantially by allowing patient rankings to depend on the kidney quality. Last, we observe that there is almost no improvement if only the healthier patients are prioritized for certain kidney types. Managerial implications: Our results verify that ranking patients differently for kidneys of different quality can reduce the survival mismatch and the kidney wastage significantly. Consequently, the policy change in 2014, that implemented prioritizing the healthiest patients when allocating the highest 20% quality organs, is a step in the right direction. For further improvement, one may consider revising the new policy by also prioritizing the least healthy patients on the waitlist for the lowest-quality organs.
Managing Capital Market Frictions via Cost-Reduction Investments
Authors: Tanrisever Fehmi , Joglekar Nitin , Erzurumlu Sinan , Lévesque Moren
Published: March 2020

Problem definition: We examine how the presence of capital market frictions influences the decision to invest in production cost reduction and the resultant production volume. This investment can increase the firm’s cash flow by increasing the profit margin, but it can also decrease the firm’s risk-free cash reserves and thus affect its exposure to capital market frictions. Academic/practical relevance: Process improvement aimed at production cost reduction has generated myriad of theoretical questions about efficient investment options and capacity choices. From a managerial perspective, process improvement is a fundamental concern in operations strategy. Nevertheless, its analysis typically excludes financial constraints by assuming a perfect capital market. Methodology: We formulate a two-stage profit maximization model in which a capital-constrained firm commits to a cost-reduction investment in the first stage in anticipation of its production decision in the second stage of this two-stage decision process. The firm considers capital market frictions when making decisions at each stage, while considering uncertainty in demand for its offering and in reducing its unit production cost. Results: When a firm faces small initial capital and low preinvestment unit production costs, it can benefit from investing in production cost reduction in the presence of capital market frictions more so than in their absence. Moreover, uncertainty in the production cost reduction mitigates the impact of market frictions on the net benefit (i.e., additional profit), whereas demand uncertainty decreases the feasible parameter space, where investing in production cost reduction is optimal. Managerial implications: A firm’s decision to invest in production cost reduction affects its operational and financial capabilities. Managers should thus consider this investment as an operational hedge not only against the uncertainty of matching supply and demand but also against exposure to capital market frictions and the resultant financial risk.

An evaluation of nurses' experiences of mentoring pre-registration students
Authors: Devlin Nuala , Duggan Seana
Published: March 2020

Nurse education in the UK has undergone a radical change over the past 30 years. The integration of nursing students within practice has evolved from an apprenticeship style to bespoke mentoring support. To act as mentors, registered nurses must have met stage 2 outcomes of the Nursing and Midwifery Council (NMC) Standards to Support Learning and Assessment in Practice, which clearly stipulate that mentors should have a reduced clinical commitment when supporting students, with one hour per week being protected, in addition to the 40% of time through direct or indirect supervision with their mentor/sign off mentor when facilitating a student on their final 12-week experience. However, this does not seem to be the case in reality. A qualitative study comprising six semi-structured interviews was undertaken across one health and social care trust. Data were analysed using Braun and Clarke's thematic analysis. A number of themes and subthemes were identified: engagement (barriers versus strategies), support (inclusivity versus exclusivity), and lack of recognition (strategic versus organisational). Due to the expected changes of supervising and assessing nursing students in practice, it is imperative that an innovative, collaborative and engaged approach is facilitated from all key stakeholders to ensure the sustainability of supporting and assessing students by registered nurses and the safeguarding of the public within clinical practice.

Hard-to-heal wounds, biofilm and wound healing: an intricate interrelationship
Authors: Azevedo Maria-Manuel , Lisboa Carmen , Cobrado Luís , Pina-Vaz Cidália , Rodrigues Acácio
Published: March 2020

Hard-to-heal wounds are a major public health problem that incur high economic costs. A major source of morbidity, they can have an overwhelming impact on patients, caregivers and society. In contrast to acute wound healing, which follows an ‘orderly and timely reparative process', the healing of hard-to-heal wounds is delayed because the usual biological progression is interrupted. This article discusses hard-to-heal wounds, the impact they have on patients and healthcare systems, and how biofilms and other factors affect the wound-healing process. Controlling and preventing infection is of utmost importance for normal wound healing. Rational use of anti-infectious agents is crucial and is particularly relevant in the context of rising healthcare costs. Knowledge of the complex relationship between hard-to-heal wounds, biofilm formation and wound healing is vital for efficient management of hard-to-heal wounds.

To what extent does evidence support decision making during infectious disease outbreaks? A scoping literature review
Authors: Salajan Andreea , Tsolova Svetla , Ciotti Massimo , Suk Jonathan E.
Published: March 2020

Background:

Infectious disease outbreaks require decision makers to make rapid decisions under time pressure and situations of scientific uncertainty, and yet the role of evidence usage in these contexts is poorly understood.

Aims and objectives:

To define and contextualise the role of scientific evidence in the governance of infectious disease outbreaks and to identify recommendations for overcoming common barriers to evidence-informed decision making.

Methods:

A scoping review and an expert workshop to provide additional input into recommendations on enhancing evidence uptake during infectious disease outbreaks taking place in European settings.

Findings:

Forty-nine records reporting on multiple decision-making processes during infectious disease outbreaks of the past ten years were included in the study. Decision makers prioritise expert advice, epidemiological data and mathematical modelling data for risk characterisation and management, but tend to be challenged by scientific uncertainties, which allow for conflicting interpretations of evidence and for public criticism and contestation of decision-making processes. There are concrete opportunities for optimising evidence usage to improve public health policy and practice through investment in decision-making competencies, relationship building, and promoting transparent decision-making processes.

Discussion and conclusions:

It is not necessarily a disregard of evidence that puts a strain on decision making in health crises, but rather competing interests and the lack of clear, unambiguous and rapidly available evidence for risk characterisation and effectiveness of response measures.

The relationship between science and public health decision making is relatively understudied but is deserving of greater attention, so as to ensure that the pursuit of evidence for decision making does not challenge timely and effective crisis management.
Third sector housing in 21st-century Hong Kong: opportunities and challenges
Authors: Yung Betty , Chan Alex
Published: March 2020

Hong Kong has a large public housing sector that shows strong resilience. Given the approximate half–half public–private housing divide in Hong Kong, officials, housing advocates and the general public envisage housing provision, problems and remedies within the ‘rigid’ framework of private and public housing. Social innovation examples of third sector housing as start-ups in ‘social housing’ have emerged in the early 21st century in Hong Kong, thereby forming a ‘new’ model in housing delivery amidst the public–private binary housing market. This study focuses on the gap filled by third sector housing in Hong Kong through serving as a complement to the private and public housing sectors in meeting unsatisfied general housing needs and as a supplement to both sectors in catering for neglected specialist housing needs. The exact future trajectory of third sector housing development will highly depend on the synergy of different stakeholders in public, private and third sectors as well as the common citizens in its nurturance.
Exact frequency domain method for the analysis of scattering from multilayer bi-anisotropic cylindrical structures
Authors: Vaseghi Noushin , Sadegh Abrishamian Mohammad
Published: March 2020

Bi-anisotropic materials have enormous and interesting applications in electromagnetic (EM) engineering. In this study, based on the state space concept, an exact and rigorous analysis of EM propagation and scattering from multilayer bi-anisotropic cylindrical structures of the general case is proposed. In comparison to the other commonly used methods in the literature, the presented method reveals a faster and more accurate analytical framework. The similar works mostly presented approximated and numerical methods for the analysis of cylindrical structures containing bi-isotropic and/or anisotropic materials as special bi-anisotropic cases. Throughout the study, the geometrical specifications and the EM excitations are chosen based on practical considerations. Since the multilayer composite is practical especially for the realization of the inhomogeneous material, the proposed approach is applied to analyze inhomogeneous bi-anisotropic cylindrical structures with more degrees of freedom in manipulation of EM waves. Our results depict an excellent conformity to the other possible solutions to compute scattering from bi-anisotropic cylindrical configurations. The mentioned comprehensiveness is one of the main advantages of our work. The suggested approach can be used as a basic step for future research related to the analysis of forward and inverse scattering problems of practical types of cylindrical structures made by complex media.

The smartphone generation of community radio listeners: Is FM sustainable?
Authors: Gordon Janey
Published: March 2020

This article examines the current environment of audio transmission services in the UK with particular regard to the community radio sector. Community radio stations in the UK are having to consider the extent to which their audiences choose to listen on an FM analogue signal and whether this is sustainable for them. The number of new platforms that a listener is using to access audio programming now includes DAB, SSDAB, TV carriers and online services. There are also developments to the actual receivers that may be used, in particular the use of smartphones to listen via online Wi-Fi or 4G. Currently there are no plans for an FM turn off in the UK and a hybrid system of transmission and reception is the most likely outcome for the foreseeable future. The consequences of this environment for the broadcasters, the listeners and the audio content are discussed in turn. A sample group of twelve community radio stations have been studied to assess current practices. This group are the remaining stations from the original Access Pilot community radio stations that went on air in 2002 and so are the oldest and most established of the UK stations. This article provides baseline definitions where relevant and uses recent data from national audience research, regulatory and other bodies to assess what people are listening to and how, along with examples from public service and commercial radio, as well as community radio.

Published: March 2020

Background and Aim: Brucellosis is an important zoonotic disease that affects fertility in farm animals. The risk factors of brucellosis have not been well studied. This study aimed to understand the seroprevalence and risk factors of brucellosis among livestock in Bangriposi block of Mayurbhanj district in Odisha, a region that borders Similipal wildlife reserve.

Materials and Methods: Rose Bengal plate test (RBPT) was carried out to estimate the seroprevalence of the livestock in this region. Bivariate analysis was carried out to analyze the association between the variables and brucellosis. Binary logistic regression was performed to assess the risk factors associated with brucellosis in the livestock.

Results: Based on RBPT, the seroprevalence of brucellosis among cattle and goats was estimated to be 1.1% and 11.2%, respectively. Binary logistic regression analysis indicates that study area, age, goats, animals with a history of abortion, and rearing practices were the major risk factors in this region.

Conclusion: This is one of the first studies in India to shed light on risk factors of brucellosis, an important neglected disease that affects the health of animals and humans and nation's economy.

Published: March 2020

Aim: This study aimed to develop equations to predict daily milk production (DMP) based on linear body and udder morphometry of Holstein Friesian (HF) dairy cows.

Materials and Methods: The experiment was conducted on 174 lactating HF dairy cows reared by farmers at different locations under similar conditions. The age, parity, and body condition score of experimental animals were limited to 0.25 of the standard deviation value above or below the average. The average DMP was based on farmers' records. Morphometry components, i.e., body length (BL); chest circumference (CC); front udder height (FUH), rear udder height (RUH); and udder circumference (UC) were directly measured using a tape; meanwhile, body weight (BW) was estimated using the Indonesia Winter formula. The relationship variables of morphometry components (body and udder morphometry) and BW on DMP were analyzed by regression.

Results: The result showed no correlation (p>0.05) between CC and BW on DMP. Meanwhile, DMP obtained linear regression (p<0.05) with the mathematical equation: 1.30+0.11*BL; 13.90+0.41*FUH; 11.02+0.18*RUH; and 3.87+0.16*UC.

Conclusion: This study shows that the DMP of dairy cows could be predicted based on their BL and udder morphometry.
A diaszpóra fogalma

Published: March 2020

The concept of diaspora has already appeared in the first translation of the Bible, in the 300s BC. However, the meaning behind the concept is hard to define. Numerous definition attempts occurred throughout the years since there is a scientific interest in this topic, but none of them is substantial. Further issues arise if we take into consideration the fact that basically every social science (history, sociology, cultural anthropology, jurisprudence, economics, political science, international relations, etc.) use the diaspora terminology without a consistent, reliable definition. Therefore, the disciplines include different attributes to the concept of diaspora which leads to a scientific chaos in this field. The paper aims to gather and demonstrate all social sciences approach to the diaspora concept and conclude the common diaspora attributes with the intention to create a comprehensive, interdisciplinary and steady diaspora definition.
Analysis and Forecast Based on the Kinetic Equation for Changing the Numerical Composition of Living Systems
Authors: Victorov Alexander Alexandrovich , Kholodnov Viacheslav Alexandrovich
Published: March 2020

The possibility of applying the kinetic theory of aging of biological species published earlier by the authors of this work to assess and predict changes in the number of specific populations is evaluated. The populations of the USA, China and Russia, as well as the population of mice observed in the experiment "mouse paradise" of the American scientist John Calhoun are considered. To this end, a historically consistent analysis of the main previously proposed multi-scenario mathematical models describing demographic data and predicting the dynamics of the population was performed. The results of these models show a decrease in the population growth rate, a tendency toward a limit with an increase in historical time, the achievement of such a limit in some developed countries with a relatively high level of social security, a subsequent decrease in the number and further uncertainty of the final population outlook in the distant future. In addition, these models made it possible to establish that the observed population growth in developed countries is unambiguously accompanied by its aging - a relative predominant increase in the number of elderly people compared to the number of the younger generation (people are aging, the population of countries is aging). In this work, the assumption was made and confirmed that the dynamics of the aging of the population of the countries of the World corresponds to the dynamics of aging of a person of one generation and is mathematically described by the differential equation of the kinetic theory of aging of living systems of the same type with close values of the parameters. The biophysical meaning of the parameters of the kinetic equation reflects G. Selye's concept of the determining role of stress in human life and populations. An analysis of the changes in the numbers of the considered populations of humans and mice at various stages of their development is qualitatively commented on from the standpoint of comparative tension according to G. Selye. To assess the degree of aging of a biological object of one population in kinetic theory, the probability of death during life is selected as an indicator of aging. In this work, the probability of reaching the maximum population size was chosen as an indicator of the aging of a biological object of various populations. The published literature predicts various options for changing the population after reaching a maximum - maintaining the reached maximum level and decreasing to a certain limit, less than the maximum achieved. In this paper, based on an analysis of its results and an analogy with the complete degeneration of mice in the “mouse paradise” experiment, a conclusion is drawn about a hypothetically possible third variant of the limiting decrease in the population - its complete degeneration.

Air-to-air refueling for a fighter platform is a force multiplier in terms of increasing its combat radius and payload carrying ability. Adapting for such a facility especially for an aircraft under design and development is a challenging task. It requires rigorous ground and flight testing to meet the certification standards. One of important flight test parameter that needs to be validated for structural impact load calculations and certification needs is the closure velocity. The air-to-air refueller was equipped with a Ram-air-turbine powered drogue and chute system. An innovative methodology of estimating the closure velocity between the drogue of the mother aircraft and the in-flight refueling probe of the receiving aircraft was evolved. The method was employed and validated during the air-to-air refueling trials of a prototype fighter platform. The intention of this paper is to explain the methodology employed and deliberate the results obtained with respect to the air-to-air refueling certification.

Published: March 2020

From the height of system-of-systems combat and operational perspective, the operations of cognitive electronic warfare (CEW) was analysed, and its main process and links were described. Secondly, the jamming effectiveness evaluation (JEE) model of cognitive electronic attack (CEA) operations was established based on the interference side, in which the change of threat degree was used as the measure index of jamming effectiveness. Then, based on the Q-learning model, an intelligent countermeasure strategy generation (ICSG) model was established, and the main steps in the model were given. Finally, on the basis the JEE model and the ICSG model, the simulation experiment was carried out for CEA operations. The result showed that combining the JEE model with the ICSG model can express the main process of the operations of CEW, as well as proved the validity of these models.

Published: March 2020

In this paper, a simple, low profile compact printed monopole antenna has been proposed for satellite based automatic identification system (SB-AIS). The design consists of a printed monopole, which has been meandered to achieve optimum size reduction. The detailed investigation in terms of bending of the arms of monopole, width of the patch and dimensions of the ground plane on the resonance frequency and input impedance is presented. The antenna is matched to a typical 50 Ω coaxial line without any requirement of external matching structures. The prototype of the antenna is fabricated and tested at an operating frequency of 161 MHz for SB-AIS, with compact size of 44.5 . 17 cm2. The measured results show that the antenna has a bandwidth of 15 MHz (9.3 per cent), gain of 1.87 dBi and beam-width of 82° in the elevation and omnidirectional in azimuthal plane. The size reduction is 53.8 per cent as compared to a linear printed monopole antenna.

Special considerations of demolition of the buildings and structures constructed without a permit on the state-owned land parcel restricted for construction
Authors: Zakashvili Ucha
Published: March 2020

The article addresses special conditions sanctioning demolition of buildings and structures erected without a permit on the state-owned land parcel restricted for construction according to the Georgian legislation and the practice of suspension of enforcement proceedings of similar resolutions by the court. It reviews the regulation envisaged by part 4 of Article 25 of Product Safety and Free Movement Code, according to which buildings constructed on state and/or self-governing unit-owned land parcels are subject to demolition and an appeal of the resolution on demolition does not suspend its enforcement. Despite the above, within the procedural legislation, the court suspends the enforcement process in the part of demolition. The article assesses the prospective of placing such buildings and structures within the legal framework in the future (compliance with the general plan, functional zoning, rules of development and use of the territory), i.e. their eligibility for obtaining a permit in deciding on the suspension/non-suspension of the demolition enforcement process. In Georgian practice, this factor is not accen­tuated by the construction control body when making a resolution on demolition, nor does the court evaluate it, which is the most significant circumstance in the process of making and enforcing such type of resolutions. Examples from the Polish and German practice where a permit allowing illegal buildings and structures to be admitted (as complying with the substantive con­struction law) is one of the most significant preconditions for making a resolution regarding demolition are presented and discussed. The circumstances to be considered in the course of suspension by the court of demolition of buildings and structures illegally constructed on state and/or self-governing unit-owned land parcels are also described, and legislative changes/ amended regulations for the sake of avoidance of procrastination of such type of demolitions have been recommended.
Potential invalidity of the decision of a public administrative body as a result of the conviction of a person performing a function
Authors: Szulc Piotr
Published: March 2020

The article presents the reflections on the potential invalidity of an administrative decision of a public administrative body as a result of the conviction of a person performing a function for an offence under Polish law. Firstly, the author analyses the legal situation of a person convicted for an offence under the Election Code (Kodeks wyborczy), the Act on Self-Government Employees (Ustawa o pracownikach samorządowych) and the Labour Code (Kodeks pracy). He examines in detail the discrepancies between the three legislative acts which may influence the legal position of a convicted person. The conclusion is that a person with the final and valid judgment for intentional offence prosecuted by public indictment to a fine or to penalty of imprisonment retains a passive electoral right in the elections for the mayor, however it seems that under the Act on Self-Government Employees it will not be possible to establish an employment relationship with such a person to work in the capacity of a self-government employee based on election. Secondly, the author analyses the potential invalidity of administrative decisions issued by a person convicted for an offence. The two conditions that could be taken into account as grounds for declaring the invalidity of an administrative decision in the context of the conviction are: a lack of jurisdiction of the authority as a condition of declaring the invalidity of a decision and a gross breach of law as a condition of declaring invalidity of a decision. The analysis of the selected conditions leads to a conclusion that there are no grounds for declaring the invalidity of a decision, as the regulations on jurisdiction will not be breached and the decision will not be issued in gross breach of law. Therefore, even if one were to consider that under the Act on Self-Government Employees a given person cannot be a self-government em­ployee, it seems that this does not prevent the issuance of administrative decisions.

Kompetencja sądu administracyjnego do uznania w wyroku uprawnienia lub obowiązku wynikających z przepisów prawa
Authors: Ciesielska Agnieszka
Published: March 2020

The purpose of the article is to present the competence of the administrative court indicated in Article 146 § 2 of the Act of 30 August 2002 – the Law on proceedings before administrative courts (LPAC). In accordance with this provision, in matters concerning complaints against an Act or an action related to public administra­tion referred to in Article 3 § 2 point 4 of the LPAC, the court may recognize in its judgment a right or an obligation arising from the provisions of law and may issue a relevant decision in the matter if it first annuls the act or declares that the action is with no legal effect pursuant to Article 146 § 1 of the LPAC. It must be emphasized however, that Article 146 § 2 of the LPAC is not an independent basis for issuing a judgment and the doctrine often presents differing views. It should be assumed that the court may recognize the right or the obligation of an individual that arises from the provisions of law if the nature of the case permits doing so and when the facts and the legal framework of the case do not raise rea­sonable doubts. Unfortunately, judicial case studies show that this possibility is rarely used. Furthermore, courts encounter numerous problems in applying Article 146 § 2 of the LPAC, most probably because of the huge controversy regarding this procedural institution. Firstly, there is no consensus as to the function of the judicial decision based on the provision in question, and the interpretation of its facultative nature is also problematic. In the author’s opinion administrative courts should use the competence referred to in Article 146 § 2 of the LPAC more frequently. Such a change of practice would increase the effectiveness of judicial review of public administration as well as will enhance the level of protection of individual rights. The article also contains some interesting examples of the application of Article 146 § 2 of the LPAC.
Cywilnoprawne aspekty umów zawieranych pomiędzy organem administracji publicznej a organizacją pozarządową w celu realizacji zadań publicznych
Authors: Biniasz-Celka Danuta
Published: March 2020

The article focuses on selected aspects of collaboration between public authorities and public benefit organizations (PBOs). PBOs not only enable the development of active citizenship, but also contribute to the effective implementation of public tasks, thus helping the authorities in implementing their statutory duties. An out­come of the collaboration may be, among other things, an agreement to implement certain tasks, taking the form of, for example, the realization of a task or the support provided for its realization following competitive tendering and in justified cases without the tender, or performed within the framework of a local initiative. The main focus of the article is to determine the scope of the autonomy of the parties in the classic approach, keeping in mind that the autonomy is one of the main principles governing civil law. Parties in a civil law contract must be able to create autonomous relationships. Consequently, in order to fulfil its functions, civil law must be an open system which regulates typical situations in a non-authoritative manner. The essential question seems to be to what extent this attitude may be transposed to public law. Undoubtedly, an agreement as a form of an administrative activity will never have the same legal nature as an agreement concluded between private parties. An administrative body that applies private law forms of action does not become subject to the same rights as a private entity and, consequently, is not exempt from the obligation to comply with the fundamental constitutional principles and values that have been established with a view of protecting civil rights and freedoms.
Is Technology Really Inclusive? Some Suggestions from States Run Algorithmic Programmes
Authors: Bertolini Elisa
Published: March 2020

The article aims at challenging the narrative that technology is inclusive with respect to states run algorithmic programmes and discusses that states resorting more frequently to technology, in particular to algorithm, are altering the traditional paradigm of the relationship between the state and the individual. Algorithm is indeed progressively twisting the traditional form of state toward a more exclusive, accountable-free and controlling form of state. The dichotomy inclusiveness/exclusiveness is at the centre of the analysis, because the state justifies resorting to algorithm by claiming that it is the suitable tool to address state’s deficiencies and making the state more efficient and effective. Hence, the state is abdicating the exercise of some important functions to the algorithm. The analysis of the most relevant algorithmic programmes implemented by states so far in the judiciary and in the welfare sector proves that the algorithm is perpetuating social bias and discrimination, thus raising significant criticalities in terms of infringements of the rule of law.
MPPT Control of PMSG Based Small-Scale Wind Energy Conversion System Connected to DC-Bus
Authors: Dursun Emre Hasan , Kulaksiz Ahmet Afsin
Published: March 2020

While the use of renewable energy systems in electric power generation is increasing more and more, wind energy conversion systems (WECS) receive considerable attention among these. Thanks to the ability of power generation in all wind speed range by controlling the rotor speed, Variable Speed WECSs are more preferred than fixed speed WECSs. When considering small-scale applications in variable speed WECS, Permanent Magnet Synchronous Generator (PMSG) based WECS structures are focus of the interest due to their advantages such as high efficiency and low maintenance costs. The generator must be operated at an optimum speed to obtain maximum power from the WECS. Moreover, different Maximum Power Point Tracking (MPPT) methods can be used to control and determine optimal operating speed. In this paper, WECS configuration consists of PMSG, uncontrolled rectifier, DC link capacitor, DC-DC boost converter and DC-Bus. Capturing the maximum power from WECS and supplying the DC-Bus is performed via tip speed ratio and PI control (TSR-PI) based MPPT method. Moreover, two wind speed profiles having constant and instant changes are created to test the performance of the proposed method. For comparison purposes, perturbation & observation (P&O) based MPPT method is also carried out in here. According to obtained results from this study performed in Matlab/Simulink environment, it is verified that TSR-PI based MPPT method ensures higher power and efficiency for these wind speed profiles by means of a more successful generator speed tracking.
Bounds on F-index of tricyclic graphs with fixed pendant vertices
Authors: Akram Sana , Javaid Muhammad , Jamal Muhammad
Published: March 2020

The F-index F(G) of a graph G is obtained by the sum of cubes of the degrees of all the vertices in G. It is defined in the same paper of 1972 where the first and second Zagreb indices are introduced to study the structure-dependency of total π-electron energy. Recently, Furtula and Gutman [J. Math. Chem. 53 (2015), no. 4, 1184–1190] reinvestigated F-index and proved its various properties. A connected graph with order n and size m, such that m = n + 2, is called a tricyclic graph. In this paper, we characterize the extremal graphs and prove the ordering among the different subfamilies of graphs with respect to F-index in
$\begin{array}{}
\displaystyle
{\it\Omega}^{\alpha}_n
\end{array}$, where
$\begin{array}{}
\displaystyle
{\it\Omega}^{\alpha}_n
\end{array}$ is a complete class of tricyclic graphs with three, four, six and seven cycles, such that each graph has α ≥ 1 pendant vertices and n ≥ 16 + α order. Mainly, we prove the bounds (lower and upper) of F(G), i.e

$$\begin{array}{}
\displaystyle
8n+12\alpha +76\leq F(G)\leq 8(n-1)-7\alpha + (\alpha+6)^3 ~\mbox{for each}~ G\in {\it\Omega}^{\alpha}_n.

On factors affecting surface free energy of carbon black for reinforcing rubber
Authors: Zhang Shangyong , Zhong Ruipeng , Hong Ruoyu , Hui David
Published: March 2020

The surface activity of carbon black (CB) is an important factor affecting the reinforcement of rubber. The quantitative determination of the surface activity (surface free energy) of CB is of great significance. A simplified formula is obtained to determine the free energy of CB surface through theoretical analysis and mathematical derivation. The surface free energy for four kinds of industrial CBs were measured by inverse gas chromatography, and the influential factors were studied. The results showed that the aging time of the chromatographic column plays an important role in accurate measurement of the surface free energy of CB, in comparison with the influences from the inlet pressure and carrier gas flow rate of the chromatographic column filled with CB. Several kinds of industrial CB were treated at high temperature, and the surface free energy of CB had a significant increase. With the increase of surface free energy, the maximum torque was decreased significantly, the elongation at break tended to increase, the heat generation of vulcanizates was increased, and the wear resistance was decreased.
