Osebnostne značilnosti sorojencev in tipi njihovega medosebnega odnosa v otroštvu
Authors: Kavčič Tina , Zupančič Maja
Published: December 2024

V študiji sva spremljali značilnosti odnosa 87 parov sorojencev in njihove osebnosti kot jih zaznavajo njihovi starši. Ob prvem merjenju so vsi otroci obiskovali vrtec, eno leto kasneje pa se je približno polovica starejših sorojencev vključila v šolo. Ob obeh merjenjih so očeti in mame neodvisno poročali o osebnostnih značilnostih svojih otrok s pomočjo Vprašalnika o medosebnih razlikah pri otrocih in mladostnikih (Halverson idr., 2003; slovenska priredba Zupančič in Kavčič, 2009) ter o pogostosti zaznanega izražanja naklonjenosti, konfliktov in rivalstva/tekmovalnosti med sorojenci pri vprašalniku Kako vidim odnos med svojima otrokoma (Kramer, 2001). Rezultati navzkrižnih analiz napovednih odnosov (med maminimi ocenami osebnosti otrok in očetovimi poročili o odnosu med sorojenci ter obratno) so pokazali, da se (a) osebnostne značilnosti obeh sorojencev in (b) ujemanje med njunimi osebnostnimi značilnosti pomembno povezujejo s pripadnostjo enemu od treh tipov odnosa med sorojenci (naklonjeni, vključeni in povprečni). Za kakovost odnosa med sorojenci je zlasti pomembna osebnostna poteza nesprejemljivost.
Povezanost med mladostnikovimi odnosi s starši in vrstniki ter uživanjem zdravju škodljivih substanc
Authors: Cugmas Zlatka
Published: December 2024

Problem raziskave je bil preučiti zveze med mladostnikovimi zaznavami odnosov z mamo, očetom in vrstnikom, nadzora s strani mame in očeta, vpliva, ki ga imajo nanj starši in vrstnik, in pogostostjo uživanja zdravju škodljivih substanc v življenju in zadnjem mesecu. V raziskavi je sodelovalo 151 študentov (43,7 %) in študentk (56,3 %), starih od 18 do 22 let. Rezultati so pokazali, da je pogostost uživanja zdravju škodljivih substanc statistično negativno povezana z mladostnikovo odprto komunikacijo ter zaupanjem v odnosu s starši in vrstnikom, stopnjo zaznanega nadzora s strani staršev ter zaznanim vplivom mame. Zveze med pogostostjo uživanja zdravju škodljivih substanc in zaznavo odtujenosti od staršev in vrstnika ter vpliva vrstnika pa so pozitivne.

Authors: Tisovec Maja , Kovačevič Petja , Golob Peter
Published: December 2024

Cilj raziskave je ugotoviti, ali bo v partnerskih odnosih odraslih, ki poročajo o manj varnem stilu navezanosti na starše v otroštvu, več menjav partnerjev kot v partnerskih odnosih odraslih, ki poročajo o varnem stilu navezanosti; ali se bodo tisti, ki menjavajo partnerje, ujemali v ljubezenskem slogu, in ali bodo značilnosti duhovnih dimenzij osebnosti drugačne kot pri tistih, pri katerih je menjavanj partnerjev manj. V vzorec je bilo vključenih 353 udeležencev moškega in ženskega spola od 15. do 66. leta starosti. Ugotovili smo, da je navezanost na starša povezana z menjavanjem partnerjev. Posamezniki, katerih starši so bili svojim otrokom na razpolago, jim nudili oporo in pozornost, so v manjši meri menjavali partnerje kot ostali, ki te podpore s strani staršev niso bili deležni. Raziskava je pokazala tudi, da sta za posameznike, ki večkrat menjavajo partnerje, značilna ljubezenska sloga igra in prijateljstvo, za tiste, ki se ne strinjajo z menjavanjem partnerjev oziroma so imeli v svojem življenju manjše število partnerski zvez, pa so značilni erotičen, pragmatičen in nesebičen ljubezenski slog. Glede duhovnosti in menjavanja partnerjev smo ugotovili, da je za tiste, ki so bolj duhovni - zlasti v smislu da so bolj predani iskanju emocionalnega zadovoljstva v molitvi ali v meditaciji, značilno večje število oseb, s katerimi so bili v partnerski zvezi oziroma so imeli z njimi spolni odnos.
Najzgodnejši odnos med otrokom in materjo skozi prizmo psihoanalitske teorije
Authors: Lorenčič Danaja
Published: December 2024

Besedilo analizira diado mati-otrok v najzgodnejši fazi seksualne organizacije, ki je po Freudu oralna ali kanibalna in v kateri obvladuje sceno prvotna navezava seksualnega vzdraženja na gon po jedi. V prvem delu je predmet obravnave otrokov razvoj v najzgodnejšem obdobju, od primarnega narcisizma, ko otrok še ne loči med sabo in zunanjim svetom, do objektnega odnosa, ko se začne zavedati, da je za zadovoljevanje potreb nujen objekt. Drugi del obravnava vlogo matere v diadi, ki se otroku prikazuje kot vsemogočni Drugi, hkrati pa predstavlja njegov "pomožni jaz". Tretji del besedila analizira rezultate oralne faze skozi prizmo objektnega odnosa, v katerem otrok gradi svoj psihični aparat.

Authors: Košir Katja
Published: December 2024

Osrednji namen raziskave je bil ugotoviti, kako učitelji ocenjujejo svojo naklonjenost dekletom in fantom v različnih obdobjih šolanja ter kako učenci zaznavajo morebitne razlike v naklonjenosti učitelja. Prav tako sem želela ugotoviti razlike med dekleti in fanti v povezanosti učiteljeve naklonjenosti ter zaznane podpore učitelja z učno uspešnostjo učencev. V raziskavi je sodelovalo 1155 učencev (učenci 5. in 8. razreda osnovne šole ter dijaki 2. letnika srednje šole) ter 50 učiteljev - razrednikov udeleženih učencev. Rezultati raziskave kažejo, da so učitelji v vseh starostnih obdobjih bolj naklonjeni dekletom kot fantom, kar je še posebej izrazito pri učencih 8. razreda osnovne šole. Dekleta so učno uspešnejša od fantov, vendar pa se dekleta in fantje ne razlikujejo v stopnji podpore, ki jo zaznavajo s strani učitelja.
Romantična navezanost odraslih in struktura osebnosti
Authors: Zeleskov Djoric Jelena , Medjedovic Janko
Published: December 2024

Glavni cilj študije je bil lokalizacija dimenzij navezanosti v implicitnem prostoru, določenem z osnovnimi dimenzijami osebnosti. Poleg tega je bil cilj študije tudi proučitev odnosov med navezanostjo in temeljnimi dimenzijami osebnosti na vzorcu 203 odraslih. Partnersko navezanost smo ocenili z Vprašalnikom izkušenj v intimnih partnerskih odnosih, temeljne osebnostne lastnosti smo ocenili z vprašalnikom NEO-PI-R. Dezintegracija, ki predstavlja operacionalizacijo shizotipije kot osnovne lastnosti osebnosti, smo ocenili z vprašalnikom Delta 10. Komponentna analiza je pokazala, da dimenziji navezanosti nista neodvisna konstrukta glede na temeljne osebnostne lastnosti. Poleg tega rezultati kažejo, da se dimenziji navezanosti nanašata na čustveno disregulacijo v intimnih medosebnih odnosih, saj smo dobili pozitivne korelacije med dimenzijama navezanosti in dimenzijami maničnosti (,35), anksioznosti (,51) ter depresivnosti (,55). Negativne korelacije smo ugotovili med navezanostjo in dimenzijama pozitivna čustva (-,34) ter občutki (-,31). Rezultati kažejo, da je dimenzije navezanosti potrebno opazovati kot izraz temeljnih osebnostnih lastnosti v partnerskih odnosih.
Anksioznost učencev in dijakov v Sloveniji: vzorec razlik po spolu in starosti
Authors: Kozina Ana
Published: December 2024

Anksioznost je čustveni, kognitivni, vedenjski in fiziološki odziv posameznika z zaznavo nevarnosti ali grožnje, katerega vzroka se posameznik ne zaveda. Ponavadi ima številne negativne posledice in moti delovanje učencev in dijakov tako doma kot v šoli. Prispevek primerja anksioznost (čustvene in kognitivne komponente) po spolu in v treh starostnih skupinah: mlajši učenci (učenci 4. razreda osnovne šole), starejši učenci (učenci 8. razreda osnovne šole) ter dijaki (dijaki 4. letnikov programov splošne mature). Uporabili smo lestvico anksioznosti za otroke in mladostnike LAOM za merjenje splošne anksioznosti ter posameznih komponent anksioznosti v šolskem okolju (kognitivnih in čustvenih). Z dvosmerno analizo variance smo ugotovili pomemben učinek spremenljivk spola, starosti ter pomembne učinke interakcije obeh spremenljivk na anksioznost učencev in dijakov. Ugotavljamo, da so starejše učenke osnovne šole v primerjavi z učenci bolj anksiozne. V skupinah mlajših učencev in dijakov razlike med spoloma niso pomembne. Starejši učenci so v primerjavi z mlajšimi bolj anksiozni, dijaki pa manj anksiozni od obeh skupin osnovnošolcev. Vzorec razlik med različnimi skupinami je skladen z izsledki strokovne literature, ki ugotavljajo višjo anksioznost pri deklicah in višjo anksioznost pri starejših učencih. Prispevek podaja pomembne primerjave anksioznosti na reprezentativnem vzorcu slovenskih učencev in dijakov in obenem odpira nova raziskovalna vprašanja ter potrebo po preverjanju ugotovitev še na drugih starostnih skupinah in z drugimi pripomočki za merjenje anksioznosti.

Does Exchange Rate Depreciation and Trade Balance Impede Economic Growth in Nigeria?
Authors: Anagun Adeyemi Michael , Agosu Peter Minasu
Published: December 2024

The Nigerian currency has experienced a significant depreciation due to its exchange with foreign currencies, particularly the dollar. This exchange rate depreciation affects purchasing power, real wages, foreign trade, debt servicing, macroeconomic stability, and interest rates. The study then seeks to fill a knowledge gap on the asymmetric link between exchange rate depreciation, trade balance, and economic growth in Nigeria. The Phillip-Perron and Augmented Dickey-Fuller unit root tests found mixed stationarity, whereas the ARDL bound cointegration test revealed a long-term link between these variables. As such, the study revealed that the depreciation of the exchange rate and trade balance positively affects economic growth. As the currency weakens, interest rates and money supply rise, and the economic growth rate rises. The study uses the error correction model to correct the disequilibrium by 59.8% to correct this economic hardship in the Nigerian economy, demonstrating that exchange rate depreciation considerably influences economic growth in the long run but not in the short term. Therefore, the practical implication is that the cost of production, importation, and inflation is high, causing fiscal restraints, governmental regulations, and economic shocks to macroeconomic stability, which may all influence economic growth. They recommend that interest rates be readjusted and that the government give grants and non-interest rate loans to small and medium enterprises to mash up with the import and export of consumable goods.
The Effect of Visitor Export, International Tourist Arrival, Foreign Direct Investment, and Labor on Economic Growth in ASEAN in 2010-2022
Authors: Sylviana Widya , Puspita Rosa Dewi
Published: December 2024

This study seeks to investigate the impact of tourism factors on economic growth, specifically international tourist arrivals (ITA), visitor exports, foreign direct investment (FDI), labor, and COVID-19 as a dummy variable in ASEAN from 2010 to 2022, both partially and simultaneously. The dependent variable in this study is the Gross Domestic Product (GDP) value. The independent variables are international tourist arrivals (ITA), visitor exports, FDI, labor, and COVID-19 as dummy variables. This study utilized dynamic panel data regression using the Generalized Method of Moments (GMM). The selected model is the System Generalized Method of Moments (SYS-GMM). The findings of this study demonstrate that all independent variables collectively exert a significant influence on economic growth across the 10 ASEAN nations. In contrast, foreign direct investment and labor considerably impact economic growth in ten ASEAN nations. In contrast, partially, international tourist arrivals, visitor exports, and the COVID-19 dummy variable have no influence.

Natural Gas Liquid Huff ’n’ Puff in Ultratight Shale Reservoirs: An Experimental and Modeling Study
Authors: Alinejad Amin , Behseresht Javad , Dehghanpour Hassan
Published: December 2024

Solvent huff ’n’ puff (HnP) is becoming a common enhanced oil recovery (EOR) practice in unconventional tight and ultratight reservoirs. For an effective HnP operation, achieving miscibility is essential for promoting solvent transport into the reservoir matrix and subsequent oil production. This is typically achieved by either increasing the injection pressure or enriching the solvent. However, injection pressure is constrained by compressor capacity, formation fracture pressure, and lateral/vertical containment. In this study, we experimentally assess the feasibility of using natural gas liquid (NGL) for HnP in an ultratight Eagle Ford (EF) shale sample, providing insights into extreme solvent enrichment scenarios in an HnP process. We hypothesize that NGL extracts oil from an oil-saturated shale core through a counterdiffusion process, primarily governed by first-contact miscibility (FCM) between NGL and oil. In this study, we explore the impact of solvent injection on the phase envelope of both dead oil and live oil during the HnP process. We present a critical comparison between C1 HnP, representing the lower limit of solvent enrichment, and NGL HnP, representing the upper limit, focusing on their respective oil recovery mechanisms and in-situ solvent-oil interactions. Using a high-pressure and high-temperature (HPHT) visualization apparatus, we investigate the interactions between NGL and oil, as well as their compositional variations, under bulk-phase conditions and in the core during the HnP process. We propose an analytical theory for the transport of NGL and oil into and out of an ultratight porous medium, explaining the experimental oil recoveries observed from the shale core. NGL and oil transport is modeled under a diffusion-dominated scenario, with FCM playing a crucial role in enhancing diffusion. Compositional analysis indicates that, contrary to C1, NGL extracts heavier oil components during the soaking stage. Core visualization demonstrates a gradual color change of NGL from clear to amber during soaking, indicating oil production via counterdiffusion. NGL expands the two-phase envelope of the dead oil, making it more volatile, while suppressing the phase envelope of the live oil. This potentially extends the duration of single-phase oil flow during the depletion stage in a live-oil system and enhances the oil production through diffusion. NGL achieves significantly lower FCM pressure (FCMP) with oil compared with C1, C1/C2 (70/30), C2, and separator gas, explaining its higher diffusion into the oil-saturated core. The analytical model demonstrates that NGL diffuses to the end of the core by the end of soaking. NGL recovers significantly more oil than C1 in the HnP process. Most of the oil is produced during soaking due to counterdiffusion, with solution-gas drive contributing additional recovery at later stages of depletion, though not as markedly as in C1 HnP.
Application of Oil Fingerprinting and Biomarker Analysis to Study Fluid Connectivity and Reservoir Isolation and Genetic Typing of Oil Obtained from the Eastern Caspian Basin (Kazakhstan)
Authors: Seitkhaziyev Yessimkhan , Jarassova Tolganay
Published: December 2024

In this paper was performed fingerprinting analysis 130 oils derived from 8 oil and gas fields in the Eastern part of Pre-Caspian basin (Laktybay, Karatobe, Karatobe South, Alibekmola, Kozhasay, Eastern Urikhtau, Akzhar Eastern, Bashenkol) for reservoir compartmentalization studies and prediction of petroleum migration pathways, while biomarker analysis of representative samples was carried out for genetic typing of oils. On the basis of the analysis performed on the area, several promising zones of hydrocarbon accumulation are identified for increasing hydrocarbon resources and reserves in the future. The results of this study showed that all studied oils of the Eastern Caspian Basin were generated from marine source rock. However, the oils of the pre-salt deposits (Kozhasay, Alibekmola, Urikhtau) were generated from carbonate source rock, while those of the post-salt deposits (Karatobe, Karatobe South) were from marine shaly ones, although within the two fields of post-salt deposits (Laktybay and Akzhar Eastern) occur oils derived from shaly and carbonate sources. Genetic typing of the studied oil samples, according to biomarker parameters, indicates the presence of two genetically different oils in Laktybay and Akzhar Eastern fields, associated with different generation sources - with source rocks of carbonate and shaly formations. According to the thermal maturity of oil from pre-salt deposits of carbonate origin (Alibekmola, Kozhasay, Eastern Urikhtau fields) showed relatively low thermal maturity in comparison with oil from post-salt deposits (Laktybay, Karatobe, Karatobe South, Akzhar Eastern).
Study on Plugging Process Parameters and Mechanism of Large-Scale Plugging Experimental Device for Blowout Preventer Stack

Published: December 2024

The blowout preventer (BOP) stack is the last line of defense for well control (pressure control of the wellbore), and the failure of its sealing components will cause serious well control accidents. At present, there is a lack of suitable experimental device to verify the feasibility of the emergency rescue method proposed for the early seal failure of the BOP stack by pumping plugging particles. However, it is costly, risky, and time-consuming to build and implement a large-scale plugging experimental model for BOP stack with ultrahigh pressure (70 MPa) and large displacement. Therefore, based on this device, this paper establishes a large-scale plugging experimental model of BOP stack by using computational fluid dynamics-discrete element method (CFD-DEM). The volume flow rate is used as the evaluation index to analyze the influence of the shape, size, concentration, and pump displacement of the plugging particle on the plugging efficiency, and the plugging parameters of the experimental device are researched and selected. The results show that the plugging particles can be divided into four stages—particle pumping, particle diffusion, particle bridging, and particle accumulation. The 5-mm spherical particle has the best plugging efficiency for the largest dimension of flange connection seal failure. The particle concentration and pump displacement affect the bridging time of particles but have no obvious effect on the plugging efficiency. A pump displacement of 2.4 m3/min and 5-mm spherical particles with 25% concentration were selected for emergency plugging of the experimental device. This study not only reduces the cost and risk of large-scale plugging experimental device for BOP stack but also further promotes the feasibility study of emergency rescue of BOP seal failure.
التحديات المعاصرة في تحقيق المواءمة بين اتفاقيات القانون الدولي الانساني والتشريعات العقابية في العراق

Study of the resonant motion of a test particle inside Kepler 69 using circular restricted three body problem
Authors: Hysa Azem
Published: December 2024

Summary: Scientific researches to discover extraterrestrial life are very intense and important. For a long time, humanity has speculated about the existence of the planetary systems different from our solar system, where extraterrestrial life can be existing elsewhere in the universe. The understanding of the origin of planets and planetary systems has indeed become a major focus of research in modern Astrophysics. Exoplanet research is one of the most field developing subjects in Astrophysics and Astronomy. Today, the number of discovered exoplanets, where life is thought to exist, is large. One of the main goals of scientists is to find Earth 2, where there is possibility of extraterrestrial life. Kepler's mission was, and is very important in the field of exoplanet research. This mission has revolutionized our understanding of exoplanets. The number of discovered exoplanets has exceeded 5780 in 4314 planetary systems, with 969 systems having more than one planet [1]. Among them, one of the most interesting is Kepler 69 c, a super-Earth around Kepler 69. This exoplanet is located at the boundary between the habitable zone and the outer one.
In this study let’s focus on the classical gravitational problem called Circular Restricted Three-Body Problem (CRTBP) [2, 3] and use an iterative method to perform numerical calculations through MATLAB software.
Therefore, in this paper, let’s try to study the movement of a “test particle”, under the action of the gravitational field of the system Kepler 69–Kepler 69 c. The aim of this paper is to study the motion of a “test particle” (for example an extrasolar asteroid test) inside the exoplanetary system Kepler 69.
Results are presented in the (x, y) plane in the rotating and inertia system. Also, some of the results are presented in the phase planes (x, vx) and (y, vy)
Clusters en Afrique subsaharienne et rôle des interventions publiques : approche théorique et méthode d’analyse
Authors: Towo Meffeu Valerie
Published: December 2024

Les clusters, concentrations géographiques d’entreprises et d’institutions connexes autour d’un même secteur d’activité, sont devenus des leviers prometteurs de transformation économique et d’innovation. Inspirées par les réussites observées dans les pays développés, de nombreuses initiatives ont cherché à comprendre les spécificités de ces clusters dans des contextes variés. En Afrique subsaharienne, toutefois, les défis structurels, économiques et institutionnels plus marqués soulèvent des questions quant à l’impact de ces particularités sur leur développement et leur compétitivité. Ce travail s’appuie sur une revue de littérature pour analyser les spécificités des clusters subsahariens, en étudiant les effets d’agglomération, les défis liés à l’allocation des ressources et le rôle crucial des interventions publiques. Les clusters informels, bien que flexibles, présentent des limites en termes de compétitivité et d’intégration aux marchés internationaux, principalement en raison de l’absence de gouvernance formelle et de liens avec les institutions de recherche et de financement. Cette étude souligne ainsi l’importance de politiques publiques stables et continues pour maximiser leur potentiel, tout en proposant des pistes pour des recherches futures sur des modèles d’intervention adaptés aux réalités africaines.
Regional and sectoral wage disparities as a reflection of inequality: The case of Kazakhstan
Authors: Tleuberdinova Aizhan , Nurlanova Nailya , Andreyeva Gulnara , Alzhanova Farida
Published: December 2024

In today’s world, many countries, including Kazakhstan, are facing growing income inequality, poverty, and an increasing polarization of society. These challenges threaten social stability and make it difficult to achieve the Sustainable Development Goals. The purpose of this study is to investigate the size and trends of regional and sectoral wage disparities in Kazakhstan, as well as to create a typology based on the average wage levels in different regions and to provide recommendations for reducing income inequality. The study tested hypotheses about the relationship between the average nominal wage and the level of GRP, level of education, industry specialization, type of ownership, and size of enterprises. The methods of expert survey, correlation, and cluster analysis were used. The study revealed the tendency of increasing inequality of labor income. The largest differences between wages in extractive industries and agriculture were revealed in the Atyrau (11.5) and Mangystau (9.2) regions and Astana (7.2). Differences in average wages between regions were estimated at 1.7 to 7.8 times. The most significant factors affecting the level of average wages are gross regional product per capita and the share of gross value added of the quasi-public sector in the gross regional product. In order to reduce differences in wages, it is recommended to introduce progressive taxation, apply regional increasing coefficients, and calculate the minimum wage based on the hourly wage rate.

Fasting of Dalā'il al-Qur'ān: Text, Reception, Transmission, and Transformation
Authors: Ichwan Mohammad Nor , Qudsy Saifuddin Zuhri
Published: December 2024

This research aims to reveal the tradition of fasting in the Qur'an at the al-Falah Kudus Islamic Boarding School. The tradition of memorizing the Qur'an cannot be separated from the practice of fasting as a form of leisure in memorizing the Qur'an. The leisure of fasting Dalā'il al-Qur'ān at the al-Falah Islamic Boarding School is carried out when the students have completed the memorization of 30 juz. In practice, this fast must be carried out with the permission of the kyai, even though the number of days is not determined. The findings presented show that the Quran has made students who memorize the Quran memorize it, not just memorize it. The Qur'an has also encouraged them to carry out other special worship activities outside of memorizing the Qur'an. This then allows the worship activity to develop from its original form. Fasting, which was originally carried out without having anything to do with the activity of memorizing the Qur'an, was then carried out within the framework of memorizing the Qur'an. Therefore, the goal to be achieved from the fast also develops. Thus, the fasting of Dalā'il al-Qur'an has made the tradition of memorizing the Qur'an influence the development of orientation and goals to be achieved through fasting.
PRÁTICAS DOCENTES E SEUS DESDOBRAMENTOS PARA A FORMAÇÃO DO LEITOR CRÍTICO
Authors: Silva Matheus
Published: December 2024

O presente trabalho tem como objetivo analisar a formação de leitores críticos a partir das práticas docentes. Para isso, firmamo-nos nas concepções de Braggio (1992), sobre os modelos de leitura, e de Leurquin (2014), quanto à proposta da aula interacionista de leitura. Utilizamos como instrumento para coleta de dados um questionário digital, enviado aos docentes com a finalidade de entender suas práticas de ensino de leitura. Percebemos que as práticas refletem a predominância do modelo psicolinguístico de leitura, provendo a interação entre leitor, autor e texto, mediadas pelo professor, com vistas ao desenvolvimento das competências a práticas cognitivas do leitor. Quanto às estratégias, observamos foco em aulas que permitem o diálogo e têm a função de instigar a leitura, mas que se apresentam de maneira pouco organizada ou detalhada. Concluímos que as práticas docentes analisadas contribuem de forma lacunar para a formação de leitores críticos, pois é necessário maior coerência entre os objetivos traçados, os modelos de leitura assumidos, as estratégias de leitura realizadas e o contexto de ensino do professor.

A região Nordeste responde por cerca de 77% da produção do país, tendo como maiores produtores os estados de Pernambuco e Bahia, os quais produziram 518,2 e 442,2 toneladas, respectivamente. Das 156 mil toneladas de mangas exportadas pelo país, 84% deste quantitativo procederam do Vale do São Francisco, sendo a manga ‘Kent’ uma das principais cultivares produzidas na região. Embora a mangueira seja uma cultura tolerante à seca, o manejo inadequado da irrigação reduz a produtividade. No entanto, algumas pesquisas concluíram que a redução da lâmina de irrigação em estádios fenológicos menos sensíveis pode não prejudicar ou até mesmo melhorar a produção e a qualidade dos frutos, com maior eficiência do uso de água. Assim, objetivou-se avaliar parâmetros fisiológicos, produtivos, qualitativos e a viabilidade econômica da mangueira ‘Kent’ quando submetida a déficit hídrico controlado nos estádios fenológicos de floração, crescimento de frutos e maturação de frutos. O experimento foi conduzido num pomar da Fazenda Special Fruit, localizada no município de Petrolina/PE, semiárido do Submédio do Vale do São Francisco. O clima da região é classificado, segundo Köppen-Geiger, como BSw'h'. O delineamento experimental utilizado foi o de blocos ao acaso, em esquema de fatorial triplo, com a aplicação de quatro lâminas de irrigação (40, 60, 80 e 100% da evapotranspiração de cultura - ETc), três estádios fenológicos (F1 - floração, F2 - crescimento de frutos, F3 - maturação de frutos) e dois ciclos produtivos consecutivos (safra de 2018 e 2019), com quatro repetições, sendo cada parcela constituída de quatro plantas. Durante cada fase fenológica, foram avaliados os parâmetros fisiológicos de trocas gasosas nas folhas: fotossíntese, condutância estomática, transpiração e temperatura foliar. Após a colheita, foram avaliados os parâmetros produtivos: número de frutos por planta, peso médio de frutos, produtividade, eficiência do uso de água e relação econômica de benefício/custo; e qualitativos: teor de sólidos solúveis, acidez titulável, pH, firmeza e coloração da casca. A irrigação com lâminas de 40% da ETc na fase de floração e 80% da ETc na fase de crescimento e maturação de frutos aumentou o número de frutos por planta, o que resultou no aumento da produtividade, eficiência no uso de água e relação benefício/custo no cultivo da mangueira ‘Kent’. A irrigação com lâmina entre 79,5 e 83,6% da ETc durante as três fases fenológicas testadas proporcionou maiores trocas gasosas, maior firmeza e acidez titulável nos frutos. A redução da lâmina de irrigação nas fases de floração e maturação de frutos diminuiu o teor de sólidos solúveis nos frutos, ao passo que na fase de crescimento de frutos o maior teor de sólidos solúveis foi obtido com irrigação entre 68,24 e 74,5% da ETc

Antecedentes y Objetivos: El matorral xerófilo en México cubre 40% de su superficie y es el más vasto de todos los tipos de vegetación. En Aguascalientes, ocupa 21.52% del territorio y presenta fuerte grado de impacto debido a la influencia humana. El objetivo del estudio fue determinar la composición florística de herbáceas en dos subtipos de vegetación xerófila y conocer los años de abandono y el tipo de cultivo que se sembraba, con la finalidad de comparar frecuencia y diversidad de herbáceas en sitios con vegetación primaria y secundaria en áreas agrícolas.Métodos: Se realizaron inventarios florísticos en matorral espinoso crasicaule y pastizal con arbustos, en sitios con vegetación primaria y secundaria ubicadas en áreas agrícolas. Se determinó el número de taxones, se calculó la frecuencia de especies herbáceas, diversidad alfa (D0), índices de Shannon-Wiener (H’), Simpson (D) y Equidad de Pielou (J’). También se realizó un análisis comparativo de los índices de diversidad.Resultados clave: Se registraron 219 especies de herbáceas pertenecientes a 140 géneros y 45 familias. En los sitios con vegetación primaria, Bouteloua chondrosioides fue la especie más frecuente y en vegetación secundaria Eragrostis mexicana. El matorral espinoso crasicaule primario tuvo la mayor riqueza con 138 especies y H’=3.49, el menos diverso es el matorral espinoso crasicaule secundario con 98 y H’=2.92. El matorral espinoso crasicaule primario tiene menos especies dominantes con D=0.05 y J’=0.83 mientras que el pastizal con arbustos primario y matorral espinoso crasicaule secundario presentan más taxones dominantes con D=0.10 y J’=0.74 en ambas condiciones. Conclusiones: En la vegetación xerófila de Aguascalientes, el estrato herbáceo tiene un índice de diversidad medio; su composición, frecuencia y diversidad están directamente afectadas por el impacto agrícola. La información generada en este estudio puede ser utilizada en la restauración de las zonas áridas impactadas por la agricultura.

Antecedentes y Objetivos: México es el segundo centro de diversificación del género Quercus con cerca de 160 especies, de las cuales 60% son endémicas. Sin embargo, existe poca información sobre sus interacciones con hongos, como la riqueza de las especies de micromicetos asexuales (MA) lignícolas en restos de encinos. El presente estudio es una contribución al conocimiento de especies de MA que se desarrollan sobre madera y corteza en cinco especies de Quercus en el municipio Huixquilucan, Estado de México, México.
Métodos: Se realizaron 15 muestreos durante 2018 y 2019, recolectando pedazos de madera y corteza, posteriormente depositadas sobre cámaras húmedas. Con los esporóforos detectados se realizaron preparaciones permanentes y semipermanentes, para su determinación taxonómica mediante el análisis de caracteres morfológicos. Los materiales de referencia se depositaron en el herbario XAL del Instituto de Ecología, A.C. en Xalapa, Veracruz, México.
Resultados clave: Se determinaron 30 taxones de MA; 28 de ellos representan nuevos registros para el Estado de México y 13 lo son para México. Se detectaron 20 especies en madera, cinco en corteza y cinco en ambos sustratos.
Conclusiones: Doce especies (40%) se reportan exclusivamente en restos lignícolas; se amplía el rango de hospederos en los 13 nuevos registros para México, así como para los MA lígnicolas en el país ((Q. laurina, Q. castanea, Q. rugosa, Q. crassipes y Q. deserticola).

Effects of Digital Sleep Interventions on Sleep Among College Students and Young Adults: A Systematic Review and Meta-Analysis (Preprint)
Authors: Lu Yi-An , Lin Hui-Chen , Tsai Pei-Shan
Published: December 2024

BACKGROUND

College students and young adults (aged 18-25 years) frequently experience poor sleep quality, with insomnia being particularly prevalent among this population. Given the widespread use of digital devices in the modern world, electronic device-based sleep interventions present a promising solution for improving sleep outcomes. However, their effects in this population remain underexplored.

OBJECTIVE

To synthesize current evidence on the effectiveness of electronic device-based sleep interventions in enhancing sleep outcomes among college students and young adults.

METHODS

A comprehensive search of PubMed, CINAHL, Cochrane Library, Embase, and Web of Science was conducted to identify randomized controlled trials (RCTs) on digital sleep interventions. Pooled estimates of postintervention and follow-up effects were calculated using Hedges’ g and 95% confidence intervals (CIs) under a random-effects model. Heterogeneity was assessed with I² statistics, and subgroup, moderator, and meta-regression analyses were performed to explore sources of heterogeneity. Evidence quality was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations framework, and data analysis was performed using Comprehensive Meta-Analysis software, version 3.7.

RESULTS

This study included 13 studies involving 5,251 participants (mean age 23.58 years; 69.55% women). Digital sleep interventions significantly improved subjective sleep quality (Hedges’ g = -1.249; 95% CI:-1.834, -0.664), sleep efficiency (Hedges’ g = 0.617; 95% CI: 0.182, 1.052), insomnia severity (Hedges’ g = -4.082; 95% CI: -5.141, -3.022), dysfunctional beliefs and attitudes about sleep (DBAS; Hedges’ g = -1.544; 95% CI: -3.329, -0.986), sleep hygiene (Hedges’ g = -0.188; 95% CI: -0.343, -0.032), and sleep knowledge (Hedges’ g = -0.268; 95% CI: 0.088, 0.447). The follow-up effects were significant for subjective sleep quality (Hedges’ g = -0.532; 95% CI: -0.956, -0.107) and insomnia severity (Hedges’ g = -2.649; 95% CI: -3.888, -1.409). The evidence quality ranged from moderate to low certainty across measured outcomes.

CONCLUSIONS

Digital sleep interventions are effective in improving subjective sleep quality and reducing insomnia severity, with moderate effects on dysfunctional beliefs and attitudes about sleep, sleep hygiene, and sleep knowledge. These interventions offer a viable approach to managing sleep problems in college students and young adults.

Authors: Bogonikolos Nikos , Papakonstantinidis Leonidas
Published: December 2024

This paper outlines the uses of artificial intelligence in social and digital infrastructure, specifically in community development and stability. It informs the reader about the reasons behind inequality in urban planning, and how big data could be used to address these issues. Additionally, it highlights the current resistance towards artificial intelligence and highlights its potential applications in the future. Building the future of local economic growth and social inclusiveness in urban communities through artificial intelligence. This paper argues that artificial intelligence (AI) can facilitate local economic growth and social inclusion by helping governments and community groups to focus on integrated efforts to identify the needs of marginalized communities. In a world where many cities are struggling with economic disparity, social exclusion and the imperative to become more sustainable, AI can help to enact the changes needed to improve the lives of residents. The focus here is on local community-led initiatives that utilize data in a strategic way, but also employ AI to optimize resource allocation and plan for a more inclusive future. Applications include AI platforms that connect residents with jobs, social services and educational opportunities based on community needs. The paper shows how strategic and targeted AI implementation focusing on community needs can strengthen urban networks, reduce social divisions and help to create a more resilient social fabric.

Analysing of Alzheimer Diseases Using Data Augmentation and CNN
Authors: Narsimha Dr. B.
Published: December 2024

Alzheimer’s disease is the most prevalent form of dementia, characterized by a progressive decline in cognitive function.
It typically begins with mild memory impairment and gradually leads to severe neurological deterioration, affecting an
individual's ability to converse, interact, and respond to their environment. This irreversible condition involves critical regions of
the brain responsible for thought processes, memory retention, and decision-making. The growing prevalence of Alzheimer’s
disease worldwide underscores the importance of timely diagnosis and effective interventions to enhance patients’ quality of life
and explore more efficient therapeutic strategies. Advanced diagnostic methods using imaging technologies, such as Magnetic
Resonance Imaging (MRI), have revolutionized the early detection of Alzheimer’s disease. These scans provide critical insights
into the structural changes in the brain, enabling researchers to differentiate between healthy individuals and those with
neurodegenerative conditions. However, manual analysis of these imaging data is time-consuming and prone to variability,
necessitating automated and robust computational approaches for accurate diagnosis. In this research, we propose a novel
framework for classifying MRI scans using Principal Component Analysis (PCA) for feature extraction, data augmentation
techniques for expanding the dataset, and a 2D Convolutional Neural Network (2D CNN) for classification.
