The “LEADER Approach” - New Development Opportunity for Rural Areas in Slovenia
Authors: Cunder Tomaž , Bedrač Matej
Published: April 2024

Integrated rural development programmes, which are prepared with the active involvement of local citizens, have a long tradition in Slovenia. In the period 1991-2006, Slovenia introduced “Programmes of Integrated Rural Development and Village Renewal” and “Development Programmes for Rural Areas”, which were quite similar to the LEADER initiative in the European Union. From the 2007-2013 programming period, the LEADER approach has been mainstreamed within the overall EU rural development policy. This means that LEADER is included in national and regional rural development programmes supported by the EU, alongside a range of other rural development axes. The main emphasis of the current paper is given to the implementation of the LEADER approach and establishment of local action groups in the 2007-2013 programming period. The paper consists of three parts. The first part presents the general characteristics of the LEADER approach and the measures which are carried out in the 2007-2013 Rural Development Programme. In the second part, an analysis of 33 Local Action Groups is described. The main focus is given to spatial-demographic characteristics, the partnership structure, and the organisation of the decision making body. The paper concludes with an analysis of 33 Local Development Strategies. We analysed the extent to which the strategic goals and priority tasks of Local Development Strategies follow the economic, social and spatial-environmental component of sustainable development.
Fighting for Survival - Planning and Development Issues in two European Rural Border Mid-Mountain Regions
Authors: Sancho Reinoso Alexis
Published: April 2024

The main aim of this article (the paper is included in the context of a research project funded by the Spanish Ministry of Science and Technology – code: SEJ-2006-15331-C02-02) is to further our understanding of two mountain rural areas occupying two distinct geographical environments: the Spanish Pyrenees and the Austrian Alps. I am particularly interested in examining the management practices that have been adopted as part of the public policies implemented in two mid-mountain regions - areas that do not have the same possibilities for development as those enjoyed by high-mountain environments. These places suffer structural problems resulting from low levels of agricultural competitiveness, accompanied by factors that impinge negatively on land use (which, in turn, condition their landscape management practices). Finally, I reflect on the differences between the two regions and their future possibilities.
Tourism and Authenticity in the Czech Villages of the Romanian Banat
Authors: Hoření Karina , Krylová Radoslava , Ulčák Zbyněk , Klvač Pavel
Published: April 2024

In the 1820s, several thousand Czechs moved to the Carpathian Mountains region near the Danube river. They founded six villages. Strict ethnic endogamy helped preserve their cultural distinction. Nowadays these villages are visited by tourists from the Czech Republic. Visits are motivated by the search for both “traditional” rural landscape and lifestyle. The paper analyses the ways of how tourists perceive the rural landscape and lifestyle, how their perceptions vary and how they influence their behaviour. It is assumed that there is a sentiment for traditional, pre-modern world. This sentiment is used for tourism promotion there. Therefore the “harmonic cultural landscape” does not only have ecological and cultural value, but its image becomes a commodity in the tourism industry.
New Challenges for Sustainable Rural Development in the 21st Century (part 4)
Authors: Lorber Lučka
Published: April 2024

The relation between rural and urban areas differs widely through the World. In some areas, particularly in Europe, the distinction between rural and urban is becoming increasingly blurred. This regards in particular rural areas close to urban centres where a process of integration of rural and urban space is taking place. Thus many rural areas, while benefiting from an increased interaction with the urban areas close by and/or from an increasingly diversified economic base, also face the challenges of losing their rural characteristics and identity. At the same time more remote rural areas with low population density and a difficult economic development face an increasing dichotomy between rural and urban areas. Over the next decade urban agglomerations will benefit from current economic and demographic trends whereas many remote rural areas face increasing difficulties and needs to better capitalise their territorial potential.

Authors: Babiak Radomír , Rosič Martin
Published: April 2024

Eastern Slovakia belongs to the most undeveloped NUTS II regions of the European Union. This region reaches high level of the unemployment rate, what together with the low production of GDP per capita forms unfavourable living conditions for its inhabitants. This article studies the development of the unemployment rate and the partial structures of unemployment in the region. It identifies key factors which affect the unemployment. It turns the attention to the potential of the region in the fight against the unemployment, from the point of view of its macro-regional and meso-regional position in the European space. It identifies specific subregions within the Eastern Slovakia and analyses its intraregional disparities in the context of labour market stability.
Petdeset let delovanje Oddelka za geografijo in študija geografije v Mariboru
Authors: Horvat Uroš
Published: April 2024

V letu 2011 mineva 50 let od ustanovitve Pedagoške akademije v Mariboru, katere ena od naslednic je tudi Filozofska fakulteta v Mariboru. V prispevku je prikazan razvoj Oddelka za geografijo in študija geografije v Mariboru, ki je v tem obdobju prešel skozi različna razvojna obdobja, tako v smislu organizacijskih oblik ter kadrovske zasedenosti, kot tudi glede na vrsto izvajanja izobraževalnih programov ter obsega znanstvenoraziskovalnega dela. Temeljno poslanstvo oddelka, to je izobraževanje kadrov za poučevanje geografije v osnovni in srednji šoli, se je izvajalo s pomočjo različnih študijskih programov. Leta 1985 je Pedagoška akademija prerasla v Pedagoško fakulteto in s tem dveletni višješolski študij geografije v štiriletni visokošolski študij, ki je bil od leta 1995 univerzitetni. Z ustanovitvijo Filozofske fakultete v Mariboru je leta 2006 Oddelek za geografijo postal del le-te, istočasno pa je prehod na nove študijske programe, ki so pripravljeni  v skladu z Bolonjsko deklaracijo, prinesel vrsto novosti, pa tudi izzivov; tako za izvajalce kot študente.
Trajnostno bivanje starejših
Authors: Kerbler Boštjan
Published: April 2024

Zaradi staranja prebivalstva se razvite države soočajo s povečevanjem finančnih potreb za zagotavljanje ustrezne zdravstvene in socialne oskrbe in s problemi zaradi premajhnih zmogljivosti ter dolgih čakalnih vrst v zdravstvenih ustanovah in zavodih institucionalnega varstva za starejše. Ker se zaradi negotovosti v gospodarstvu in vse večjega deleža neaktivnega prebivalstva finančne zmožnosti držav, da bi zagotavljale sedanjo raven ter obseg zdravstvenih in socialnih storitev, zmanjšujejo, se vse bolj pojavljajo zahteve po bolj trajnostnih načinih bivanja in storitvah za starejše. Članek izhaja iz domneve, da je zamisel uresničljiva s preureditvijo bivalnih enot in selitvijo oskrbnih storitev v domače okolje starejših ljudi, s čimer bi bilo starejšim zagotovljeno, da bi čim dlje časa ostali v svojem bivalnem okolju, v katerem bi bili sposobni živeti čim samostojneje in čim bolj kakovostno.
Napovedovanje učinkov ukrepov spodbujanja javnega prevoza potnikov
Authors: Lep Marjan , Hmelak Simon
Published: April 2024

V Sloveniji že leta izjavljamo, da želimo imeti bolj trajnostno mobilnost, na terenu pa lahko ugotovimo drugačna dejstva. Pri razvoju sistema javnega potniškega prometa se sprašujemo predvsem, kam investirati javni denar, da bo prišlo do želenih premikov v izboru načina potovanja. V podporo nosilcem odločanja je razvit model v obliki enačbe, s pomočjo katere je moč  verodostojneje napovedati učinke ukrepov, kot so integrirana enotna vozovnica, bistveno znižanje cene vozovnic, sprememba cene parkiranja v mestih, povečanje obsega ponudbe vlakov itd.. Model je validiran in umerjen na vzorcu potovanj na delo iz okoliških naselij v Maribor.

Authors: Skalicky Vanja , Sitar Metka
Published: April 2024

Poglavje izpostavlja nekatere vidike socialne trajnosti v urejanju in prenovi stanovanjskih sosesk, ki so bile v Sloveniji praviloma osedotočene na gradnjo večstanovanjskih objektov in objektov z javno vsebino ter odprtih površin oz. površin namenjenih mirujočemu prometu. Kot fenomen predstavljamo značilne vplive skandinavskih modelov, zlasti švedskih, ki so korenito spremenili urbanistično in arhitekturno prakso v Sloveniji in jo obravnavamo iz  zgodovinske vidika s poudarkom na organizaciji in načrtovanju povojne izgradnje stanovanjskih sosesk v Mariboru. Sodobne metode urbane prenove kot odločilni dejavnik izpostavljajo nove pristope v načrtovanju odprtega prostora za dvig kakovosti urbanega okolja in s tem kakovosti bivanja na splošno.
Biomonitoring rastlin in okolja za trajnostno izvajanje varstva narave
Authors: Paradiž Jasna
Published: April 2024

Tekom desetletnega biomonitoringa rastlin na Ljubljanskem barju smo preučili populacijsko dinamiko pri vrsti Fritillaria meleagris in Solidago canadensis. Izvedli smo tudi bioteste za oceno ogroženosti mokriščnih rastlin zaradi onesnaževanja okolja. Podatki s topografskih kart so pokazali zmanjšanje gostote populacij ogrožene vrste F. meleagris na opazovanih mestih, medtem ko se je razširjenost S. canadensis povečala na celem območju. Na osnovi rezultatov citogenetske analize različnih vrst je ugotovljena povečana stopnja genotoksične ogroženosti rastlin na Ljubljanskem barju v primerjavi z drugimi lokalitetami. Biomonitoring rastlin se priporoča za zgodnje odkrivanje škodljivih učinkov onesnaževanja, in ob ekoremediacijah služi za trajnostno izvajanje varstva rastlin v naravnih habitatih.

Authors: Rajović Goran , Bulatović Jelisavka
Published: April 2024

The paper analyzes the socio-economic and geographic factors for Berane Andrijevice and  Plava. The above urban settlements are located in the northeastern part of Montenegro. Isolated traffic and geographical position adversely affects the economic and social development of urban settlements. For the development of cities of greater importance are the geo-morphological and hydrological characteristics of the terrain, the climate and geology, which limits greatly compensates for modern construction techniques. Berane population increased in the period 1948-2003 to 26.81%, while in Andrijevica decreased by 42.48% and 12.43% of Plav. These data suggest to us most vividly, what are the demographic changes occurring in the region. Age groups, due to migration and decreasing birth rate changes and gets unfavorable features - reducing the proportion of younger and older increases the proportion of the population. In both cases, the disturbed age structure has a reverse effect on the movement of the  population (the size of reproductive contingent), but also to all other structures of the population (the size of contingent employment, population, compulsory school contingent, contingent dependent population ratio).The main characteristic of modern urban development of cities provide processes of industrialization and urbanization. However, the economic crisis in Montenegro at the beginning of the nineties due to isolation, the economic and social strategy of circling and lack of long term economic development, stopped the social, economic, technical and technological development of urban settlement Berane, Andrijevica and Plav.

Demographic characteristics of population of Slovenian cities in the first decade of 21st century
Authors: Kelc Stanko
Published: April 2024

We analyzed available statistical data to establish present demographic characteristics of the population of Slovenian cities and their recent changes. According to the statistical definition of cities the share of urban population in Slovenia represents half of its total population. The number of population in Slovenian cities is generally decreasing or stagnating, the coefficient of masculinity was growing in the last decade, but not much more than in Slovenia in general, the ageing of population was also a bit faster in urban areas and their ageing index is considerably higher than the Slovenian average. Urban areas also had a considerably larger share of immigrants from abroad in comparison with the national average while employed and unemployed persons were relatively equally distributed among urban and other areas. The level of education was considerably above the national average. We also compared natural growth data which showed that urban areas in 2002 experienced the decrease that was below national average and the increase in 2011 that was also lower than in Slovenia in general.

Authors: Matušková Alena , Rousová Magdalena
Published: April 2024

The article deals with the development of the labour market in the city of Pilsen after 1989, which was significantly influenced by the transformation of the local industry. Apart from the traditional indicators of the labour market, the authors also deal with the proportion of foreign workers. Over the past decade, a dramatic growth of foreigners has been depicted, which was caused by the arrival of foreign investors in Pilsen as these have created a number of job opportunities for less qualified workers. The aim of the contribution is to identify both positive and negative social aspects of life in Pilsen as these are influenced by the development of the situation on the labour market in the city and also to monitor the internal and external factors influencing the development.
Coexistence of different social groups around one of the campuses of the University of Pécs
Authors: Makkai Bernadett , Gyüre Judit
Published: April 2024

In the process of urban transformation and renewal, large numbers of immigrants are expected in connection with the existence of prosperous branches of industry. It is assumed that in an environment where higher education is one of the most important economic factors, there will be conflicts in the everyday coexistence of social groups. The aim of this study is to investigate, in a city quarter which was forced to transform due to economic structural changes, and which has a bold mixture of ageing people and temporary university residents, how the coexistence of different groups of the society influences the quality of life in the quarter, and how the situation is perceived by the affected people themselves. Furthermore, we want to see what kinds of tension arise from the interactions between these groups with dissimilar/different background, and what possible solutions can be found to resolve such tension.
Transformacija turistične infrastrukture in obiska v Mariboru v zadnjih dveh desetletjih
Authors: Horvat Uroš
Published: April 2024

The paper presents the development of tourism in Maribor, with a focus on major changes in the tourist offer (especially tourist infrastructure and accommodation facilities) and tourist visit since 1991. Changes in tourist flows to South-East Europe, the great economic crises and the collapse of the major industrial companies in Maribor was followed by a large decrease in tourist visit and the need for transformation of the tourist offer in the city. In Maribor was built a range of new hotels and other accommodation facilities, which resulted in the fact that since 2000 increased diversity and quality of the tourist offer and, consequently, has gradually started to increase also the tourist visit. However, Maribor still shows all the characteristics of a tourist destination with the dominant urban tourism, which is characterized by short average length of stay of tourists and the high share of overnight stays in hotels.

Prostorske značilnosti staranja prebivalstva v Sloveniji: primerjalna analiza deleža starejših v obdobju 1981–2013 po upravnih enotah
Authors: Kerbler Boštjan
Published: April 2024

Za slovensko prebivalstvo je značilno, da se pospešeno stara. V članku zato izhajamo iz domneve, da ta proces v slovenskem prostoru ni enovit in da obstajajo pri nas različna območja staranja. Pri tem smo se osredotočili na obdobje 1981–2013, ko se je staranje prebivalstva v Sloveniji intenziviralo. Rezultati primerjalne analize so potrdili našo domnevo in določena so bila štiri območja staranja, ki so posledica različnih oblik selitvene mobilnosti slovenskega prebivalstva. V zaključku so podane smernice za nadaljnja raziskovanja dinamike staranja prebivalstva v Sloveniji.
A Comparative Analysis of Life style of the Local People before and after the Construction of the Dams in the Sub Zone of Mendefera: A Case Study of Adi-Mengoti and Mai-Aron Dams
Authors: Afsar Alam Mohammad , Khan Masihulla
Published: April 2024

Eritrea is one of the Sahelian countries in the Horn of Africa facing acute shortage of water. In areas where rainfall is low and unreliable, the construction of dams is utmost important for irrigation, domestic and livestock uses. Agriculture is the mainstay of Eritrean people; it has been playing a vital role in the process of economic development. It is estimated that about 75 per cent of the population depends on agriculture and allied activities. In such a country where agriculture is the backbone of the economy regular supply of water for irrigation is as important as the veins and arteries in the human body. In fact, dams serve multi purposes i.e. water supply for agriculture and domestic uses, flood control, hydro-power generation, navigation, fisheries and recreation activities. But in Eritrea, dams are mainly constructed to supply water for irrigation, domestic, industrial and livestock uses. This research paper is carried out to examine a comparative analysis of life style of the local people before and after the construction of the dams in the sub zone of Mendefera (Zoba Debub, Eritrea).
Domače naloge pri pouku geografije - učni izzivi ali le obveznosti?
Authors: Kolnik Karmen , Dobnik Tanja
Published: April 2024

V prispevku so predstavljena nekatera teoretična izhodišča, ki opredeljujejo domače naloge kot pomemben del učnega procesa. Učenci z njimi dopolnjujejo pridobljeno znanje in razvijajo sposobnosti pri predmetu, predvsem pa se usposabljajo za samostojno učenje in prepoznavanje osebne odgovornosti zanj. S študijem primera predstavljamo  raziskavo o pogostosti, namembnosti in vsebini domačih nalog pri pouku geografije ter motiviranosti učencev in učiteljev zanje na osnovni šoli Petrovče. Rezultati kažejo, da se učenci in učitelji na teoretični ravni sicer  zavedajo pozitivnega vpliva domačih nalog na učenčevo učenje in razvijanje samostojnosti. Kljub temu učenci nalog ne opravljajo redno, učitelji dajejo premalo raznolike in diferencirano osmišljene domače naloge.

Ademais, o estudo contribui com a estruturação do processo de feedback enquanto estratégia de ensino, considerando a operacionalização, regras e especificidades a se observar em sua aplicação.
Progress in developing and deploying drought-tolerant and insect-pest resistant climate-resilient droughtTEGO® and TELA® maize varieties
Authors:   African Agricultural Technology Foundation (AATF), Oikeh Sylvester
Published: April 2024

Currently, drought stress and associated insect-pest damage pose a huge threat to food and nutrition security for over 300 million people in Africa who depend on maize as their main food source. Recurrent drought events cause an annual 17 to 25 percent yield loss of maize in Africa [1]. Compounding the impact of drought, is the ravaging effect of insect-pests infestation on maize production, especially for pests whose population pressure is highly triggered under dry conditions. The crop under weakened conditions created by drought stress and pest effect further becomes constrained biologically and physiologically, thus limiting the crop’s ability to use already limited water and nutrients from the soil. The major insect pests of maize in Africa are fall armyworm (FAW, Spodoptera frugiperda) and various stem borer species (Spotted stem borer (Chilo partellus), African stem borer (Busseola fusca), and the pink stemborer (Sesamia Calamistis). For instance, in Kenya alone, an average of 13 percent or 400,000 tons of maize is lost to stem borer, which is equivalent to the annual maize imports, valued at USD 90 million [2]. The FAW, a transboundary pest, first observed in the continent in 2016, is a maize pandemic that if not controlled adequately, could potentially destroy up to 20 million metric tons of maize annually, enough to feed 100 million people in Africa [3].
„Nowa sztuka” w Łodzi w dwudziestoleciu międzywojennym
Authors: Pawłowska Aneta
Published: April 2024

Artykuł prezentuje okoliczności kształtowania się sztuka modernistycznej, wielkoprzemysłowego miasta jakim była Łódź w okresie dwudziestolecia międzywojennego. Fabryczny charakter wielonarodowego, dynamicznie rozwijającego się miasta wywarł wpływ na jego kulturę i sztukę. Poprzez fakt licznego uczestnictwa w ruchu artystycznym diaspory żydowskiej (ekspresjonistyczne ugrupowanie Jung Idysz) oraz abstrakcjonistów (Władysław Strzemiński, Katarzyna Kobro, Karol Hiller, Stefan Wegner, Aniela Menkesowa) miasto „kulturowej pustyni” urosło do rangi ważnego ośrodka sztuki nowoczesnej. Ważnym działaniami wspierającymi rozwój sztuk nowoczesnej w Łodzi było stworzenie Międzynarodowej Kolekcji Sztuki Nowoczesnej w łódzkim muzeum oraz wydawnictwa z tzw. Biblioteki „a.r.” (wiążące się z praktyką artystyczną grupy „a.r.”).

Published: April 2024

En los últimos años, los Vehículos Aéreos No Tripulados (VANT) han presentado una variedad de aplicaciones. Estudios recientes demuestran sus ventajas al momento de cuantificar áreas para la estimación de escorrentía pluvial. Sin embargo, existen incertidumbres sobre su alcance real. Ante ello, el objetivo del estudio es estimar el volumen pluvial captado por cubiertas mediante VANT. La metodología consistió en seleccionar una zona de estudio compuesta por una variedad de cubiertas, en el que las áreas fueron medidas digitalmente, esta última por medio del procesamiento de imágenes captadas por VANT. Para el cálculo de volumen de escurrimiento, se tomaron los datos de precipitación media mensual de los últimos 11 años, y se consideraron los Coeficientes de Escorrentía (Ce) reportados en la literatura. A continuación, se calculó el volumen de escurrimiento medio mensual para cada cubierta. Los resultados muestran que las cubiertas estudiadas (Coliseo - Biblioteca), tienen la capacidad de captar un volumen anual de 2237.75 m3. Con un volumen promedio de 406.74 m3 durante la época lluviosa (noviembre a marzo) y 29.15 m3 en la época seca (abril a octubre). Aunque el uso de VANT permite determinar uno de los valores dentro del cálculo de volumen de escorrentía, para lograr un resultado más exacto, es preciso analizar y evaluar las otras variables (Ce y precipitación).

La producción de miel tiene vestigios ancestrales, considerando a Apis como la más domesticada y comercializada. Por otro lado, las abejas meliponinos, que tienen vestigios precolombinos han sido poco estudiadas y tiene propiedades fisicoquímicas importantes y de gran valor para ser usadas en el área agrícola. El cultivo del mango, del cual dependen una variedad de familias por ser un soporte socioeconómico, además de lo anterior, se le invierte bastante para sostenerlo con un buen manejo agronómico, donde hay insuficiente herramientas biológicas que permitan dar una producción menos dañina al ambiente. El objetivo del presente trabajo fue evaluar la acción elicitora de metabolitos de defensa y de la inducción de crecimiento de los frutos de mango al aplicar miel. El estudio se llevó a cabo en el rancho San Juan, en el municipio de Tapachula, Chiapas. Se establecieron 4 tratamientos en campo, considerando las etapas de producción del fruto de mango. Se encontró diferencias significativas entre las concentraciones de fenoles totales analizadas en hojas y entre todos los tratamientos, observando que es mejor realizar la aplicación de miel después de la floración y durante el crecimiento del fruto de mango. No importa la concentración de miel utilizada, ambas estimulan el crecimiento del fruto de mango. Se encontró una relación significativa entre las concentraciones de fenoles, tiempo de aplicación y crecimiento del fruto de mango, con miel de M. beecheii.

Authors: Volokitin A. , Volokitina N.
Published: April 2024

The Vylys Tom 3 Mesolithic site is part of the Izhma-Tom geoarchaeological microregion, where there are now 6 Mesolithic sites explored by excavations. The site is located on the right bank of the middle course of the Izhma river in the vicinity of the village Tom, Izhma region of the Komi Republic, on the remnant of a pine forested fluvial terrace above floodplain. It was discovered in 2018 and then surveyed in 2021, 2023. On the excavated area the concentration of finds with a diameter of 4-5 m was revealed, accompanied by fragments of calcified bones and charcoal. Small concentrations of finds were located around it. Radiocarbon date for charcoal is 8150±90 years ago (LU-10576).

The collection includes a polished axe, abrasive tools and a large hammerstone. The flint inventory contains a large number of small cores in the final knapping stage. At the same time, large and very large specimens predominate among the blades and tools made of them. Attention is drawn to the presence of the so-called core-burins, there are burins on broken blades, a large number of scrapers. Large points are available.

The lithic industry of the Vylys Tom 3 site is similar to the industries of the nearby Mesolithic sites Vylys Tom 2 and Ochyu katishche.
The «ceremonial» side of the public life of the merchants of the Vologda province in the second half of the XIX century
Authors: Leyman I.
Published: April 2024

Despite the fact that the history of the Russian merchants has been of great interest to researchers for more than two decades, there are still little studied aspects in this area, including the «ceremonial» side of the public life of representatives of the merchant class. This area of research activity seems very promising, as it can significantly complement the sociocultural portrait of the merchant class. The purpose of this paper is to recreate the picture of the participation of the merchants of the Vologda province in festive and solemn events as an important part of public life in the second half of the XIX century. Based on the «Vologda Provincial Gazette» for 1861-1899, using the methods of formalizing and systematizing historical data, such components of the «ceremonial» side of the public life of the local merchants as the celebration of important dates related to the Romanov House; accompanying members of the imperial family who visited the province; participation in official events organized by the Governor; Clubs membership were identified. The published materials indicate that the merchants took an active part in local celebrations dedicated to the events from the life of merchants, as well as provided significant financial support to the related various charitable initiatives. The most important events of the provincial authorities could not do without representatives of the merchant class. Besides, in the second half of the XIX century, the general urban leisure space for a wide range of people, including merchants, began to take shape. These aspects nevertheless allow us to outline the main facets of the «ceremonial» side of the public life of the merchants of the Vologda province in the second half of the XIX century and set directions for further research.

O presente texto apresenta as reflexões oriundas da pesquisa de mestrado acadêmico em educação realizada no âmbito do Programa de Pós-graduação em Educação da Faculdade de Educação da Universidade Federal de Uberlândia (PPGED/FACED/UFU). O estudo teve como objetivo problematizar o currículo da educação superior, em específico da formação de professoras(es), a partir dos pressupostos elucidados pela decolonialidade. Estabelecemos interlocuções com a Pedagogia Universitária e buscamos compreender como a discussão étnico-racial se coloca no contexto curricular da graduação em Pedagogia da referida instituição. Nesse ínterim, a opção metodológica adotada nesta pesquisa se baseou na revisão bibliográfica, com a análise dos Projetos Político Pedagógicos (PPPs) e das fichas das disciplinas de dois cursos de graduação em Pedagogia da UFU nos Campi Pontal, em Ituiutaba/MG, e Santa Mônica, em Uberlândia/MG. Consideramos que as problematizações a respeito da descolonização do currículo da formação docente, sob a perspectiva da educação para as relações étnico-raciais se fazem necessárias enquanto tensionamentos ao modelo hegemônico de produção do conhecimento. Destarte, salientamos que o processo de formação de professoras(es) deve estar envolto às discussões concernentes às pautas decoloniais, o que proporciona, junto às(aos) estudantes, vivências curriculares que expressam suas identidades individuais e coletivas.

The aim of this study is to explore the relationship between student engagement, brand image, student satisfaction and loyalty. Furthermore, the study intends to explore the mediating role of student satisfaction in the relationship between engagement and loyalty as well as brand image and loyalty in the context of higher education.  A representative sample of 296 students from the three best private universities in Dhaka has been gathered in order to test the hypotheses. The study demonstrates that brand image has a favorable impact on student satisfaction while student engagement has no influence on student satisfaction. The results show that loyalty is heavily influenced by the student satisfaction construct. When there is no mediation between student engagement and loyalty, a complete mediation is recognized when student satisfaction is a mediator between brand image and student loyalty. The study also reveals that there is a negative correlation between student engagement and satisfaction. The results of the research definitely improve brand perception which keeps students engaged to their higher education.

Integrating metallic lithium (Li) with a three-dimensional (3D) host is a popular strategy for long-life Li composite anodes, where the structure and physicochemical nature of the framework are critical for the electrochemical performance. Herein, Li-rich dual-phase barium (Ba)-based alloy composed of BaLi4 intermetallic compounds and Li metal phases is thermally incorporated into commercial carbon cloth sheets to develop Li-Ba alloy composite (LBAC) anodes featuring a porous array of BaLi4 microchannels as the built-in 3D skeleton. Doping of metallic Ba can greatly lower the surface tension of liquid Li and improve the wettability of the molten Li-Ba alloy toward the carbon cloth substrate. Moreover, LBAC benefits from the superior lithiophilicity and the porous architecture of BaLi4 skeleton nested in a conductive carbon fiber matrix, leading to stable cycling performance by confining Li stripping/plating in microchannels network of BaLi4 alloy framework and dissipating high current densities. As a result, the LBAC symmetrical cells can run stably for 1,000 h under 1 mA cm-2 and 1 mA h cm-2, and the capacity retention can retain 93.3% after 300 cycles in the full cell with areal capacity of 2.45 mA h cm-2. This work offers a smart designing strategy of 3D Li alloy composite anodes by introducing porous and lithiophilic alloy scaffold as sub-framework of the carbon hosting anode, promising the prospect of Li metal batteries for future applications.

Published: April 2024

In today's financially constrained business landscape, companies often grapple with challenges related to allocating capital expenses, resulting in a scarcity of reservoir characterization data. This shortage necessitates the optimization of existing data and the estimation of unavailable reservoir properties. While classical correlations in core analysis traditionally used porosity to predict permeability, the intricate interplay of lithology and pore geometry renders this approach unreliable for exclusive permeability estimation from porosity. This study aims to advance the understanding of the Tortonian reservoir in the Gamma oil field by exploring the combined application of Flow Zone Indicator (FZI), Artificial Neural Network (ANN), and Convergent Interpolation (CI) methodologies. Utilizing data from an exploratory well and four appraisal wells, the study seeks to model the intricate non-linear relationships between Tortonian reservoir properties, determine effective porosity, estimate permeability for uncured wells, and create a comprehensive permeability map for the Tortonian oil reservoir.

The results reveal the presence of three distinct rock types within the Tortonian reservoirs and successfully establish estimates for effective porosity and permeability logs. Notably, the generated permeability map demonstrates a direct correlation with the porosity map, validating the proposed methodology. Through the integrated use of FZI, ANN, and CI techniques, the reliability of the porosity-permeability relationship is significantly enhanced, achieving an impressive accuracy of 90%. This study effectively models the nuanced non-linear porosity-permeability relationship within the Tortonian reservoir, offering an economically viable means to enhance reservoir characterization within the constraints of a limited capital budget and accessible data sources.

Background: Colorectal cancer (CRC) is the second most lethal cancer in the United States (U.S.) with the highest incidence and mortality rates among African Americans (AAs) compared to other racial groups. Despite these disparities, AAs are the least likely to undergo CRC screening, have precancerous colorectal polys removed, and have CRC detected at stages early enough for curative excision. In addition, compelling evidence links inflammatory dietary patterns to increased CRC and cardiovascular disease risk. Studies show that AA churches can successfully engage in health promotion activities including those related to cancer control. The current study seeks to leverage church-placed Community Health Workers (CHWs) to increase CRC screening and reduce CRC risk.
Design and Methods: We aim to (1) increase guideline concordant CRC screening uptake using church-placed CHWs trained in screening with a validated instrument, Brief Intervention using Motivational Interviewing, and Referral to Treatment (SBIRT); and (2) reduce dietary risk factors (inflammatory dietary patterns) linked to CRC. The latter will be addressed by culturally adapting an existing, web-based lifestyle program called Alive!. Using a Hybrid Type 1 Implementation-Effectiveness cluster randomized design, we will randomize 22 AA churches into either the dual intervention arm (CHW-led SBIRT intervention plus Alive!) or a usual care arm comprised of CRC prevention educational pamphlets and a list of CRC screening sites. We will recruit 440 subjects and evaluate the effects of both arms on screening uptake (colonoscopy, fecal DNA) (primary outcome) and dietary inflammation score (secondary outcome) at 6-months follow up, and Life Simple7 (LS7) - a cardiovascular disease (CVD) risk score - at 6 months and 1-year (secondary outcome). Finally, guided by a racism-conscious adaptation of the Consolidated Framework for Implementation Research (CFIR), we will conduct a mixed- methods process evaluation with key stakeholders to understand multi-level influences on CRC screening and CVD risk behaviors.
Discussion: Church-placed CHWs are trusted influential connectors between communities and health systems. Studies have shown that these CHWs can successfully implement health prevention protocols in churches, including those related to cancer control, making them potentially important community mediators of CRC screening uptake and CRC/CVD risk reduction.

Published: April 2024

Vascular endothelial cells are closely related to tumor progression, and extracellular vesicles (EVs) play an important role in this process. EVs derived from breast cancer cells also affect the biological characteristics of human umbilical vein endothelial cells (HUVECs) to promote tumor progression. However, the mechanism remains unclear. In the present study, EVs derived from MDA-MB-231 and MCF-7 breast cancer cells were extracted at different concentrations (0, 10, 20, and 40 μg/ml). Specific concentrations of breast cancer cell line EVs (10, 20, and 40 μg/ml) significantly increased the proliferation, Colony formation, and migration of HUVECs (P < 0.05) compared to MDA-MB-231 and MCF-7 breast cancer cell-derived EVs. There was no significant difference in the expression levels of total JAK2 and STAT3 protein (P < 0.05), while the expression levels of P-JAK2 and P-STAT3 protein increased significantly (P < 0.05). In conclusion, EVs derived from breast cancer cells may promote the proliferation and migration of HUVECs by regulating the phosphorylation of the JAK2/STAT3 signaling pathway.

A contactless control of fluctuations of phase space variables of a nanoobject belongs among the key methods needed for ultra-precise nanotechnology and the upcoming quantum technology of macroscopic systems. Here we utilize the experimental platform of a single levitating nanoparticle (NP) to demonstrate essential protocols providing linear amplification of the mechanical phase space variables together with squeezing of phase space probability distribution. The protocol combines a controlled fast switching between the parabolic trapping potential and either weak parabolic or inverted parabolic amplifying potential leading to amplification of mean value and variance (fluctuations) along an arbitrary phase space variable and squeezing along the complementary one. The protocol is completed with cold damping scheme to control the initial fluctuations of the NP phase space variables. We reached the amplification gain |G|>2, the squeezing coefficient above 4 dB, and the second-order energy correlation function approaching 3 which corresponds to a maximum for a stochastic non-equilibrium classical state. These experimental results will already allow pre-amplification and manipulation of nanomechanical NP motion for all quantum protocols if the NP cooling towards the ground state is applied.

Purpose The goal of this study was to explore whether the clinical benefits of percutaneous coronary intervention (PCI) are sustained in acute coronary syndrome (ACS) patients with abnormally increased platelet counts (PC). Methods Patients with elevated PC enrolled in the Improving Care for Cardiovascular Disease in China–Acute Coronary Syndrome Project between July 1, 2017, and December 31, 2019 were evaluated. Elevated PC was defined as a baseline PC ≥ 300 × 109/L. The primary outcome was net adverse clinical events (NACEs), which included major adverse cardiovascular or cerebrovascular events (defined as cardiac death, myocardial infarction, ischemic stroke, and stent thrombosis) and major bleeding, during the index hospitalization. The risk of NACEs was compared between the PCI and non-PCI arms by multivariable analysis and inverse probability of treatment weighting. Results Among 4,526 patients, the proportion of patients receiving PCI decreased with increasing PC, and 3,046 patients ultimately underwent PCI. Those patients had a lower rate of NACEs (adjusted odds ratio [OR]: 0.54; 95% confidence interval [CI]: 0.37–0.78; P = 0.001) and a lower risk for ischemic events (adjusted OR: 0.33; 95% CI: 0.22–0.50; P < 0.001). No in-group differences in major bleeding were identified (adjusted OR: 1.41; 95% CI: 0.62–3.18; P = 0.41). Similar findings were obtained in inverse probability of treatment weighting. Conclusion In ACS patients with increased PC who have more complex thrombohemorrhagic profile, PCI can effectively reduce the risk of ischemic events without increasing the risk of bleeding.
