It is shown that the modern development of weapons and military equipment will trigger the issue of improving artificial intelligence systems, in particular, their gradual convergence with human intelligence. It is shown that this requires the discovery of the algorithmic basis of artificial intelligence systems, including on the basis of the transition to multivalued logics. A close relationship has been established between the algebraization of natural language and the creation of the language of combat neural networks distributed systems in which processing is carried out based on the same operations that are involved in the human brain. The basis for this is the natural definition of language as a transpersonal structure, which largely determines the nature of human intelligence. A universal means of aggregating police multi-valued logics is provided, many elements can be placed at the disposal of General Galois. Thus, an analogue of the Zhegalkin polynomial is used, which is valid for achieving multi-valued logic with the use of properties (the Zhegalkin polynomial itself applies only to the case of binary logic). A selective case study that proves the constructiveness of the proposed application, a discoverable solution that tests the operation of a ternary adder using a Galois field containing three elements.

The paper provides a description of the mathematical model for various processes that have a life cycle (beginning and end). The implementation of the mathematical model is shown on the example of the spread of coronavirus in Russia over 2 years. The proposed model allows predicting the number of infected people in the coming period. The adequacy of the model for the process under consideration is determined by the accuracy of the root-mean-square error of 0.8%. The model can be used to predict temporal processes in social, demographic, medical, industrial and other areas.
Reliability and Validity of Self-Hate Scale in Turkish Community Sample
Authors: Büge Burcu , Bilge Yusuf
Published: April 2022

The purpose of this study was to adapt the self-hate scale (SHS; Turnell et al., 2018) into Turkish in a community sample, and test the validity and reliability of the measure. The study was conducted with 234 individuals. After the translation procedures, the language equivalence was examined, and a significant positive relationship was found between the Turkish and English forms. Findings of the reliability and validity analyses indicated that the Turkish SHS confirmed seven items in one factor with good factor loadings. Good fit values and reliability coefficients were determined with the SHS-Turkish Form. Self-hate was positively correlated with self-disgust, behavior-based self-disgust, physical appearance-based self-disgust, depression, anxiety, and interpersonal sensitivity. Self-hate also indicated a negative correlation with self-compassion. Simple linear regression analyses results showed that self-hate predicted depression, anxiety, and interpersonal sensitivity scores. These results demonstrated that the SHS-Turkish Form can be validly and reliably performed to Turkish culture.
The Art of Leadership – An Understanding
Authors: Mbutu Paul , Mongare Walter
Published: April 2022

Purpose: The purpose of this paper is to give a general overview of the term “leadership” as used and explained by different authors and how it is situated in the context of group or organizational communication. I will attempt to give various definitions of key terms and concepts used in leadership discourse. Key questions like; what is leadership? What does it mean? Who is a leader? What does a leader do? Types of leaders and types of leadership styles or approaches will be explored.

Methodology: The paper adopted a desktop methodology research design. Key words such as leadership styles, leadership, leader, leadership approaches, and leadership communication skills were used to source published papers from popular search engines such as google and scholar. The published papers were then assessed for quality and those found relevant were used to generate results. The type of data analysis method used was qualitative data analysis. Specifically, content analysis was used to identify key themes and research gaps from papers.   

Findings: Transformational leadership was found to be a critical fundamental tool, particularly in the concept of getting others to buy into necessary changes in the environment, such as workplaces, communities, and government institutions. Another finding is that leadership is the transformational credibility and capacity of men and women in institutions, communities, regions, nations, and international settings to influence people emotionally, intellectually, relationally, and willfully toward shared vision, purpose, mission, goals, objectives and activities. Therefore, any leader taking up this model must continue to be an inspiring presence, one who leads by example and is responsible for motivating others. It appears to be a form of leadership well-suited to these current times characterized by uncertainty, and societal instability.

Unique contribution to Theory, Policy and Practice: The paper sheds light on the role that leader’s personal communication skills play in leadership. Transformational leadership is a theoretical dimension to leadership styles and types that merits consideration. Policy makers may prescribe the need for transformational leadership in the various policy documents such as the constitution sections which advocate for leadership and governance among public and private institutions. Leaders in all fora could apply transformational leadership in a bid to improve leader-follower performance outcomes.

English-medium Instruction through the lens of discipline and culture
Authors: Zuaro Beatrice
Published: April 2022

In the last few decades, English-medium Instruction (EMI) has been the focus of a rapidly increasing body of research. While such research has tended to cover certain aspects of the phenomenon extensively, others still remain under-researched. For example, in focusing primarily on STEM (Science, Technology, Engineering, and Mathematics) disciplines, EMI investigations have devoted limited attention to the potential relevance of disciplinary differences. Similarly, while EMI has been noted to differ from context to context, the practical implications of cultural differences in EMI implementations continue to be overlooked. The present study aims to shed some light on the role played by disciplinary and cultural specificities via an investigation of beliefs and reported practices of 13 Italian lecturers. The lecturers were selected to represent a variety of disciplinary backgrounds and individually interviewed about their experiences as teachers and scholars. The interviews were subsequently subjected to a thematic analysis. The results reinstate to an extent the influence of disciplinary culture; however, they also point to an important role played by the local culture in shaping both beliefs and practices. Additionally, the results also reveal a nuanced understanding of the opportunities and challenges of EMI among these participants, stressing the need for more attention to cultural mediation in international higher education.

Published: April 2022

Liquid storage tanks are important components of lifeline and industrial facilities. They are critical elements in water supply scheme and fire fighting system, and extensively used for storage and processing of variety of liquid like material such as petroleum product, liquefied natural gas, chemical fluid and wastage of different forms. In this paper, the seismic response of base isolated cylindrical liquid storage tanks is investigated under real earthquake ground motion. The isolation systems considered is elastomeric bearings (without lead core), the specific objectives of the study are to carry out the comparative performance of the tanks with isolation and without isolation (i.e. Fixed tanks) also to investigate the response of the tanks for varying capacity with varying heights. For this study forty tanks of varying heights such as 8m,10m,11m,11.5m,12.5m,14m,16m with varying capacities of 500kl,265kl,200kl,100kl,50kl are considered. For this a time history analysis has been carried out by using a three time history of varying magnitude with varying peak ground acceleration. It is observed that the base shear of elevated liquid storage tanks supported on shaft is significantly reduced due to isolation. The drift of the tank relation to base of shaft is also significantly reduced due to isolation. The earthquake response of isolated short tanks is relatively more, i.e. Isolation is not effective for stiffer shafts, and however in general, the effectiveness of base isolation is achieved for tall tanks. Although the effectiveness of seismic isolation increases with the increase of bearing flexibility and damping these properties needs to be modified for desired response.

Published: April 2022

With the cheapening of virtual and augmented reality technologies, sectors such as tourism have started to invest in new ways of promoting destinations, providing an improvement in the user's travel experience. In Brazil, the scenario is no different, private tourism agencies and government agencies responsible for this sphere, invest through their secretariats in the development of products and services allied with these technologies. The objective of the article is to bring a national vision of the scenario, gathering examples of the use of technologies, contributing knowledge through scientific results. The data were collected using a Boolean research formula directed to the official government tourism pages and carried out through the Google search engine, all links that involved the terms "virtual reality" and/or "augmented reality" categorized within the tabs related to tourism on government websites. After analysis of the 84 links recovered, 22 showed adherence to the proposed theme. These were divided by states and regions of Brazil and characterized according to the information published in each of them. The results show a low rate of use of these technologies as some small confusions about the concepts of each one of them. In the whole country, the Midwest and Northeast regions are the ones that presented the largest quantitative and diversified use of augmented reality and virtual reality technologies for government agencies.
Restorative proctocolectomy with an ileal reservoir
Authors: Morgan Wyn P.
Published: April 2022

Panproctocolectomy with a permanent incontinent ileostomy has become the gold standard in the surgical management of ulcerative colitis, and is often necessary in the treatment of polyposis coli. The advantage of this technique is that it completely removes all intestinal disease in one stage, with a low operative mortality, and eliminates the possibility of malignant change. Many patients, however, regard the acquisition of a stoma for the remainder of their lives as a major disadvantage. This latter factor may cause patients to delay surgery beyond the optimum time, and dissuade polyposis families from undergoing screening evaluation.

FLOC: Hesitant Fuzzy Linguistic Term Set Analysis in Energy Harvesting Opportunistic Clustering Using Relative Thermal Entropy and RF Energy Transfer
Authors: Anees Junaid , Zhang Hao-Chun
Published: April 2022

Limited energy resources and sensor nodes’ adaptability with the surrounding environment play a significant role in the sustainable Wireless Sensor Networks. This paper proposes a novel, dynamic, selforganizing opportunistic clustering using Hesitant Fuzzy Linguistic Term Analysis- based Multi-Criteria Decision Modeling methodology in order to overcome the CH decision-making problems and network lifetime bottlenecks. The asynchronous sleep/awake cycle strategy could be exploited to make an opportunistic connection between sensor nodes using opportunistic connection random graph. Every node in the network observe the node gain degree, energy welfare, relative thermal entropy, link connectivity, expected optimal hop, link quality factor etc. to form the criteria for Hesitant Fuzzy Linguistic Term Set. It makes the node to evaluate its current state and make the decision about the required action (‘CH’, ‘CM’ or ‘relay’). Our proposed scheme leads to an improvement in network lifetime, packet delivery ratio and overall energy consumption against existing benchmarks.

Published: April 2022

This paper proposes a new technique to construct a hybrid zero cross-correlation (NZCC) based on multiple diagonal (MD) code for two-dimensional (2D) spectral amplitude coding for optical code division multiple access code division multiple access (SAC-OCDMA) systems. The proposed hybrid code eliminates totally the multiple access interference (MAI) between a large number of users and allows them to connect simultaneously via the optical communication link with a high speed to receive huge data and serve various areas such as Internet, telephony, DAB radio, digital audio broadcasting, and DVB video. Simulation results demonstrate that the performance of such a SAC-OCDA system based on novel 2D hybrid NZCC/MD code can be easily improved keeping a less complex structure using couplers for direct spectral/spatial dimension (SDD) detection and show superior bit error rate (BER) values comparing to previously developed two-dimensional codes including perfect difference (2D-PD), diagonal Eigen-value units (2D-DEU), multi-service (2D-MS) and balanced incomplete block design (2D-BIBD) codes.
Constructing New Collective Signature Schemes Base on Two Hard Problems Factoring and Discrete Logarithm

Published: April 2022

In network security, digital signatures are considered a basic component to developing digital authentication systems. These systems secure Internet transactions such as e-commerce, e-government, ebanking, and so on. Many digital signature schemes have been researched and published for this purpose. In this paper, we propose two new types of collective signature schemes, namely i) the collective signature for several signing groups and ii) the collective signature for several individual signings and several signing groups. And then we used two difficult problems factoring and discrete logarithm to construct these schemes. To create a combination of these two difficult problems we use the prime module p with a special structure: p = 2n +1. Schnorr's digital signature scheme is used to construct related basic schemes such as the single signature scheme, the collective signature scheme, and the group signature scheme. The proposed collective signature schemes are built from these basic schemes. The proposed signature scheme is easy to deploy on existing PKI systems. It can support PKIs in generating and providing a unique public key, a unique digital signature, and a unique digital certificate for a collective of many members. This is essential for many collective transactions on today's Internet.

Authors: K Sonwalkar Prakash , Kalmani Vijay
Published: April 2022

With the rising popularity and advent of many services on Wireless Sensor Networks (WSNs), there is a compelling need to have energy-efficient solutions. The sensors and devices are powered by batteries whose life is limited, and at times it is impossible to replace the batteries, especially in remote applications. In such a scenario, Energy Harvesting (EH) stands as an undisputed candidate for enhancing the network lifetime. Radio Frequency (RF) energy is the most commonly available, ubiquitous, and reliable energy source among all the available energy sources. While RF signal carries both information and energy, EH is possible for long-distance and mobile environments. This work discusses initial research in the domain of EH in wireless networks via Radio Frequency (RF) signals. The paper presents an EH rectenna for energy harvesting over 2.45 GHz (Wi-Fi band). The receiving antenna is designed to pick up the radio signal in the RF range (2.45 GHz) from the free space. The four patch elements design has an antenna substrate made with RT with a dielectric constant of 2.2. The paper presents the simulation results of the basic parameters of the antenna, such as return loss, input impedance, bandwidth, gain, directivity, and efficiency. H-shaped slot antenna and modified H-shaped antenna (with circular slot) are designed with a gain of 8.24 dB and 8.32 dB, return loss of -10 dB and -16 dB, and bandwidth of 64.8 MHz and 868 MHz. The high gain, large bandwidth, properly matched impedance for minimum return loss, and high efficiency of the modified H-shaped patch antenna makes it eligible for energy harvestin.
The life course of caregivers of patients with chronic disease in Tiznit- Morocco: Case of hemodialysis.
Authors: Elbouzidi Mohamed , MAHDANE Mhamed
Published: April 2022

Chronic diseases, including end-stage renal disease, are a health problem. Without the voluntary involvement of caregivers and their assistance, the management of these diseases is beyond the capacity of the health care system. Although the caregiving function offers a sense of usefulness and satisfaction, it can be a heavy burden. This can hurt all aspects of the caregiver's life course. 
our study aims to describe the life course of caregivers of patients with a chronic disease, the case of hemodialysis patients, in Tiznit, Morocco.
Data collection is carried out by a semi-structured interview guide with 37 participants. The main results show that the life course of caregivers of people with chronic disease is impacted by hemodialysis. Indeed, the disease influences negatively all spheres of their daily life including the physical sphere with sleep disorders and fatigue, the psychological sphere with a feeling of shock and fear, and the social sphere with the feeling of isolation.
In this sense, this paper aims to highlight the importance of the problem of caregivers of people with hemodialysis in Tiznit, Morocco.
Similarly, to improve the care of patients with chronic diseases, it is important to take into account the life course of family caregivers. They play an essential role in the care of patients and make a considerable contribution through their emotional, moral, and material support to the person being cared for, as well as through the time they devote to the patients, in the tasks and acts of daily life that they perform for them.

Published: April 2022

O enxerto ósseo autógeno tem sido o mais utilizado na odontologia, no entanto, sua disponibilidade limitada, defeito da área doadora, morbidade e desconforto do paciente, têm dificultado seu uso. Essas deficiências levaram à descoberta de uma nova fonte de enxerto ósseo autógeno processado de dentes humanos. Objetiva-se avaliar a eficácia de enxertos de dentina extraída de dentes humanos para a neoformação óssea. O estudo trata-se de uma revisão integrativa da literatura, na qual foram feitas buscas nas plataformas PubMed e EBSCOhost, sendo eleitos nove artigos. O uso da matriz dentinária desmineralizada (MDD) do dente extraído do próprio paciente, se assemelha ao osso alveolar em estruturas químicas e nas fases orgânica e proteica. A matriz dentinária é utilizada como material para enxertia óssea onde promove o processo de regeneração óssea, incluindo preservação de alvéolo de extração, aumento de crista, enxerto ósseo sinusal e regeneração óssea guiada. Além disso, possui capacidade de osteoindução, osteocondução e substituição progressiva. A MDD apresenta intra e extra-porosidade, que aumentam o suprimento sanguíneo e favorecem a lenta reabsorção do material enxertado, o que auxiliará na cicatrização. Deste modo, esse biomaterial possui vantagens como baixa morbidade, fácil manuseio, ausência de antigenicidade e alta capacidade de remodelação do osso, apresentando segurança e eficácia para enxertia óssea.

Excess soil moisture and fresh carbon input are prerequisites for methane production in podzolic soil
Authors: Korkiakoski Mika , Määttä Tiia , Peltoniemi Krista , Penttilä Timo , Lohila Annalea
Published: April 2022

Abstract. Boreal upland forests are generally considered methane (CH4) sinks due
to the predominance of CH4 oxidizing bacteria over the methanogenic
archaea. However, boreal upland forests can temporarily act as CH4
sources during wet seasons or years. From a landscape perspective and in
annual terms, this source can be significant as weather conditions may cause
flooding, which can last a considerable proportion of the active season and
because often, the forest coverage within a typical boreal catchment is much
higher than that of wetlands. Processes and conditions which change mineral
soils from acting as a weak sink to a strong source are not well understood.
We measured soil CH4 fluxes from 20 different points from regularly
irrigated and control plots during two growing seasons. We also estimated
potential CH4 production and oxidation rates in different soil layers
and performed a laboratory experiment, where soil microcosms were subjected
to different moisture levels and glucose addition simulating the fresh
labile carbon (C) source from root exudates. The aim was to find the key
controlling factors and conditions for boreal upland soil CH4
production. Probably due to long dry periods in both summers, we did not
find occasions of CH4 production following the excess irrigation, with
one exception in July 2019 with emission of 18 200 µg CH4 m−2 h−1. Otherwise, the soil was always a CH4 sink (median
CH4 uptake rate of 260–290 and 150–170 µg CH4 m−2 h−1, in control and irrigated plots, respectively). The median soil
CH4 uptake rates at the irrigated plot were 88 % and 50 % lower
than at the control plot in 2018 and 2019, respectively. Potential CH4
production rates were highest in the organic layer (0.2–0.6 nmol CH4 g−1 d−1), but some production was also observed in the leaching
layer, whereas in other soil layers, the rates were negligible. Potential
CH4 oxidation rates varied mainly within 10–40 nmol CH4 g−1 d−1, except in deep soil and the organic layer in 2019, where potential
oxidation rates were almost zero. The laboratory experiment revealed that
high soil moisture alone does not turn upland forest soil into a CH4
source. However, a simple C source, e.g., substrates coming from root
exudates with high moisture, switched the soil into a CH4 source. Our
unique study provides new insights into the processes and controlling
factors on CH4 production and oxidation, and the resulting net efflux that
should be incorporated in process models describing global CH4 cycling.

Published: April 2022

There is a growing recognition that there needs to be a shift from firefighting to wildfire prevention (through fuel and landscape management and engagement with stakeholders) of which disaster risk reduction plays a major role. In the Netherlands, where flood and water has been centrally managed from 1798, there has been a shift from fighting against water (disaster management) to flood risk reduction and living with water. The same approach is needed in integrated fire management and thus there are lessons that can be learnt from this for society, agencies and government. Integrated fire management which consists of science-based decision making by multidisciplinary teams through cooperation and collaboration of parties involved and affected. Fire science is multi-disciplinary and needs to be addressed in a multi-disciplinary manner. Challenges faced in both sectors are similar in terms of scale, governance and engaging with society. A systematic literature review lead to the identification of lessons from Dutch water management and Room for the River Programme that may be applied to integrated fire management. In the Netherlands there is a recognition that (flood) risk management should be a programmed, flexible process of continuous improvement of management practices by active learning about current interventions and drivers of change. The expected results will provide guidance on how to improve prevention of wildfires within Integrated Fire Management.
Theoretical OH stretching vibrations in dravite
Authors: Fuchs Yves , Fourdrin Chloé , Balan Etienne
Published: April 2022

Abstract. Density functional theory is used to investigate the vibrational stretching
properties of OH groups in ideal and chemically disordered dravite models.
Different schemes of cationic occupancy are considered, including the
occurrence of vacancies at the X site and Mg–Al inversion between the Y and
Z sites. The harmonic coupling between different OH groups is found to be
smaller than 1 cm−1, indicating that the OH stretching dynamic in
dravite can be described by considering a collection of nearly independent
single OH oscillators. Their harmonic stretching frequency is linearly
correlated with the corresponding OH bond length and most of the bands
observed in the experimental vibrational spectra can be interpreted as
consequences of the cationic occupancy of the sites coordinated to the OH
group. The V(OH) and W(OH) stretching frequencies are affected by
the Mg–Al inversion and by the presence of vacancies at the X site. In this
last case, the frequencies depend on the isolated or more concentrated
character of the X vacancy distribution along the c axis. Based on
theoretical stretching frequencies, new interpretations are proposed for
some of the bands experimentally observed in synthetic samples of dravite
and magnesio-foitite.
Innovative design method for planar mechanism configuration based on component similarity discrimination
Authors: Hong Weiwei , Chen Jinxi , Ye Bingliang , Cui Rongjiang
Published: April 2022

Abstract. Obtaining new models of mechanical equipment to conduct mechanical
innovative design through kinematic chain configuration synthesis is an
effective method. However, in practice, due to the existence of similar
components, existing innovative design methods easily produce redundant
design schemes, which require extensive isomorphic discrimination
operations, and the design process is complex. In view of existing problems,
this study analyzes a method for discriminating between similar components of
mechanisms from the perspective of graph theory and then applies it to the
specialization of topological graphs to solve the problem of redundant design
schemes. Finally, using the innovation of a drilling rig drilling arm mechanism
as an example, 52 feasible schemes without redundancy are
obtained. This paper provides a reference for the innovation of the configuration of
planar mechanisms without design redundancy.

Authors: Saeed Adel , Mohammed Alkhader S. K. , Al-Salimi Mokhtar S.S.
Published: April 2022

Eight trace elements (Al, V, Ni, As, Ba, Cd, Pb, and Hg) were quantitatively studies in three kinds of hen egg samples (home, street, and market hen eggs) collected from different regions in Aden city-Yemen including Al-Buraiqeh, Al-Hiswah, Khormaksar, and Shaikh Othman. Samples were wet digested and quantitatively analyzed by the Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) technique. Neglecting not detected values (ND), the range concentrations (in ppm units) of elements in hen’s eggs were in the range 0.407-7.414 for Al, 0.116-0.645 for V, 0.320-3.130 for Ni, 14.35-21.21 for As, 0.180-4.700 for Cd, 1.372-4.054 for Ba, and 12.078-15.14 for Pb. Since Yemen country does not screen the explored elements in this foodstuff, the recent work was done by comparing the results with other values reported in the literature and international standards. The mean concentrations of some studied elements such as arsenic, cadmium, and lead in some samples were exceeded the acceptable limits as detailed by presented international specifications and standards. The systematic national testing of hen's eggs production and the quality of environment and hen's feeds should be considered to protect public health.

Tratamiento virtual de aneurismas cerebrales
Authors: Nicolás Dazeo,
Published: April 2022

Los stents desviadores de flujo son habitualmente usados para tratar aneurismas cerebrales debido a su capacidad de modificar los factores hemodinámicos locales. Una dificultad de este tratamiento es poder predecir su impacto. Para ello se puede utilizar la simulación computacional, que provee el valor de cada variable en cada punto e instante. Pero una de sus dificultades es el costo de modelar de forma eficiente las mallas de alambres. Una técnica para reducir el costo computacional de las simulaciones es modelando las mallas de alambres como medios porosos. Existen distintos de estos modelos en la literatura pero faltaba una comparación entre ellos en cuanto a dificultad de implementación y rendimiento. Algunos modelos representativos son relevados en este trabajo y presentados con una simbología unificada. Luego, son comparados en geometrías idealizadas contra modelos de alambres trenzados y simplificados. También se implementa una aplicación capaz de simular medios heterogéneos y se comparan modelos tanto homogéneos como heterogéneos en geometrías anatómicamente precisas obtenidas de distintos pacientes. Los modelos de medios porosos mostraron ser más rápidos que los de alambres de forma explícita con márgenes de error variados. Entre las variantes heterogéneas uno de los modelos mejora respecto a su homologo homogéneo mientras que el otro empeora. Finalmente, se aplica uno de los modelos de medios porosos a los aneurismas con dispositivos intrasaculares. Estos dispositivos están constituidos de una malla de alambre, al igual que los stents. Se comparan dispositivos de distintos tamaños en diferentes geometrías anatómicamente precisas. Los resultados muestran que los valores hemodinámicos globales no varían, pero existen diferencias locales respecto a la velocidad y tensión en las paredes.
La excursión escolar en la Ciudad de Buenos Aires (Fines del siglo XIX y segunda década del siglo XX) : diálogos histórico-didácticos entre pasado, presente y viceversa
Authors: Marta Alicia Libedinsky,
Published: April 2022

Esta tesis reconstruye un momento particular del devenir del campo disciplinar de la Didáctica a través de una estrategia de enseñanza elegida como objeto informador -la excursión escolar -y de un abordaje de corte histórico -didáctico que abarca la visión europea, la norteamericana y la local en la Ciudad de Buenos Aires entre fines del siglo XIX y la segunda década del siglo XX. En ese período en la fundamentación y justificación de las propuestas de enseñanza y de aprendizaje para las escuelas primarias se entrecruzan paradigmas: el positivismo y el pragmatismo progresivista (que es base del movimiento internacional de la Escuela Nueva) los que - al tiempo que pugnan por diferenciarse desde sus supuesto teóricos y sus concreciones - dan origen y continuidad a esta innovación didáctica. La excursión escolar se expresa como una práctica de enseñanza que conecta las escuelas, la ciudad y sus instituciones, se realiza bajo normativa específica y alineada a planes de estudio y programas vigentes considerando tres momentos, antes, durante y después. Es decir, la preparación accediendo a clases y materiales didácticos, los traslados en tranvía y a pie desde las escuelas hacia los diferentes lugares de destino en la ciudad y las visitas a barrios, plazas, parques, museos, fábricas, edificios gubernamentales, exposiciones, bibliotecas, otras escuelas y el regreso al aula, donde la excursión escolar es representada en composiciones, dibujos y lecturas. Se trata de una investigación cualitativa y documental signada por la impronta del método de análisis temático y el lema que la guía es “desandar para no naturalizar lo escolar” activando a través de la trama pasado-presente y viceversa un diálogo histórico-didáctico al conectar ese punto de partida con experiencias y conceptualizaciones didácticas actuales. Se abordan adicionalmente perspectivas alternativas para el afianzamiento de una didáctica urbana en clave histórica y elementos para la renovación de la disciplina Didáctica que podrán dar lugar a nuevos debates y futuras investigaciones las que -como este estudio-reconozcan lo general en lo particular.
Management performance of local public administration and the qualitative criteria for its evaluation
Authors:   State Agrarian University of Moldova, Fetescu Cezara
Published: April 2022

Currently, the notion of “performance” is infiltrating with safe steps in public management. Attempts to assign concrete qualities to the performances registered by the LPA management are more and more frequent, in order to identify some possibilities to quantify these performances. The article tries to clarify what the performance itself entails, and then to identify the qualitative criteria that are relevant for the evaluation of these performances. In order to establish the criteria, the legal prerogatives of the LPA that ensure the increase of the quality of life in the local community, as well as the needs and expectations of the community were taken into account, for the simple reason that the objectives of civil servants must be correlated with community needs.

Published: April 2022

Scientific and theoretical methodology tends to penetrate the essence of the investigated phenomena and processes. This is possible on the condition of a comprehensive approach to the object of study, starting with its appearance and its continuous development. The relevance of the research is the hypothetical justification of the reconsideration, which can be obtained by solving the invoked problem. The science of administration fully investigates the activity of the state in order to capitalize on the tourist potential aiming at the optimal fulfillment of its tasks, the satisfaction of general interests and the defense of interests, in the codifications of amplifying the role that public administration has as main tool.
