THE PAKISTAN HEALTHCARE SECTOR AT STAKE: BRAIN DRAIN OF PAKISTAN DOCTORS
Authors: Dr. Fareha Khaliq  , Waqas Zaigham  , Saqib Yaqoob Malik
Published: February 2025

Background: The exodus of Pakistan's medical personnel is a major problem for the country. The nation's already overburdened healthcare system suffers from this brain drain, which results in a lack of qualified professionals and subpar patient care. This exodus is caused by a number of factors, including political instability, a lack of prospects for professional progression, and inadequate compensation. The exodus of highly skilled healthcare workers from Pakist an, sometimes known as "medical brain drain," is a growing concern that jeopardizes the country's healthcare system. As economic disparities, gender biases, and professional hurdlesdrive doctors, nurses, and other medical professionals outside, Pakistan h as a serious shortage of medical workers. The purpose of this study is to investigate the fundamental causes and implications of medical brain drain, to identify the biases that worsen the problem, and to provide concrete solutions to reduce its impact on Pakistan's healthcare system. This research emphasizes the importance of specific policies aimed at improving healthcare working conditions, reducing gender disparity, and raising investment in medical training and infrastructure. Objectives: The study's objectives are to determine and examine the main factors that lead Pakistani physicians to look for work overseas and to evaluate the resulting effects on the country's healthcare system. Materials and Methods: A variety of methods, including surveys, expe riments, and observational studies, may be used in quantitative research. The study used a quantitative research design and a cross sectional survey approach. Results: A sizable portion of physicians cite low pay, unfavorable working circumstances, and a d earth of prospects for professional growth as reasons for their choice to immigrate.Furthermore, the situation is made worse by political unpredictability and security worries, which drive many people to look for safer and more stable surroundings. Conclu sion : Pakistan's healthcare sector is seriously threatened by the continuous exodus of medical personnel. To solve this problem, extensive reforms are needed, such as bettering pay packages, improving working conditions, providing them the opportunities fo r their specialization trainings, grand maintaining political stability to keep talent in the nation. Therefore, in order to reduce brain, drain out of the nation, governments in developing nations like Pakistan should concentrate onpolicies that guarante e job opportunities are available, offer suitable research facilities, provide safe working conditions, and establish merit systems. In conclusion, it is critical to highlight that Pakistan has substantial obstacles in developing and successfully implement ing migration related policies since there is a dearth of a substantial database with international migration statistics. Therefore, among other things, keeping such a database up to date is essential for the proper execution of policies.

ZASTUPLJENOST EKOLOŠKOG ODGOJA I OBRAZOVANJA U OSNOVNOJ ŠKOLI
Authors: Hasanbašić Esma
Published: February 2025

Današnje čovječanstvo susreće se sa velikim ekološkim problemima, kao što su: globalne klimatske promjene, zagađivanje vode i zraka, nestašica pitke vode, degradacija i destrukcija tla, sve veća produkcija otpada i njegovo neadekvatno zbrinjavanje, neracionalna potrošnja prirodnih resursa itd. U vremenu globalne ekološke krize obrazovanje i odgoj za zaštitu okoliša se postavlja kao najvažniji zadatak, jer najneposrednije utiče na stvaranje ekološke svijesti i ekološkog ponašanja. Osnovnoškolsko obrazovanje ključno je razdoblje u čovjekovom životu i jako je važno na vrijeme postavljati temelje ispravnog odnosa prema svijetu oko nas. U tom periodu djeca postaju ekološki pismene i osviještene osobe, a upravo razvijanje ekološkog mišljenja u savremenom odgoju i obrazovanju su od iznimne važnosti. Prirodne nauke imaju zaista veliki značaj u razvoju društva, jer osposobljava učenike za djelovanje u svijetu u kojem se njeguje misao ekologije, kao i ekološka svijest. Dakle, znanje iz prirodnih nauka omogućava učenicima primjenu u svakodnevnom životu i takva znanja su preduvjet za shvatanje međuzavisnosti prirodnih sistema i čovjekovog mjesta u njima. Međutim, da li je zaista dovoljno pažnje posvećemo ekološkom odgoju i obrazovanju danas? Cilj rada jeste analizom Nastavnih planova i programa iz predmeta prirodnih nauka u osnovnoj školi utvrditi zastupljenost sadržaja i aktivnosti ekološkog odgoja i obrazovanja u školama Tuzlanskog kantona.

NEZAVISNOST CENTRALNE BANKE
Authors: Čović Esad , Kajtazović Ibrahim
Published: February 2025

Danas je u svijetu jedno od ključnih pitanja u domeni finansija: da li su i koliko centralne banke (ne)zavisne? Pri tome se pod nezavisnišću Centralne banke, kao najviše monetarne vlasti zemlje, podrazumijeva da je ona institucionalno nezavisna, da je oprativno nezavisna pri izboru instrumenata monetarne politike (regulacije), da postoji nezavisnost njenih upravnih organa od zakonodavne i izvršne vlasti i da je finansijski nezavisna. Odgovor na navedeno pitanje zavisi i od ustanovljenog modela funkcionisanja Centralne banke, odnosno da li je u pitanju model nacionalne Centralne banke, model nadnacionalne Centralne banke, složeni model Centralne banke ili nazovi model Valutnog odbora (Currency boarda). Stoga će predmet analize u ovom radu biti način funkcionisanja četiri navedena modela u kontekstu njihove (ne)zavisnosti. Za predstavnika prvog modela uzeta je Centralna banka Švajcarske (SNB), za drugi model Evropska centralna banka (ECB), za treći model FED SAD, a za četvrti model Valutni odbor Centralne banke BiH. Na kraju, izvršena je komparacija ovih modela sa aspekta njihove (ne)zavisnosti.
PRISILNE ARBITRAŽE
Authors: Đurić Nikola
Published: February 2025

Namera je ovim radom razjasniti značenje prideva “prisilna” uz reč arbitraža, a koji se vezuje uz arbitražne postupke koji su za stranke nadležni nezavisno o postojanju njihove volje da spor reše upravo na takav način. Takve arbitraže suprotnost su ostalim arbitražama po nedostatku volje i saglasnosti stranaka da sporove reše pred izabranim telom i u skladu sa izabranim pravilima ili pravilima tog izabranog tela, kao bitnog elementa koji razlikuje “prisilne” od “dobrovoljnih” arbitraža. Stranke u ovim slučajevima često nemaju ni prethodnog saznanja o telu nadležnom za rešavanje sporova, pa čak ni o pravilima koja će se primenjivati postupku, a što može znatno uticati na konačno ostvarenje i zaštitu prava iz takvog pravnog posla ili odnosa. Također, po mojem mišljenju, neki autori svojstvo “prisilne arbitraže” (arbitrage obligatore, compulsory arbitration, Zwangsshiedsgerich) neosnovano priznaju i onim arbitražnim sudovima čija nadležnost je ipak zasnovana u ugovorima sklopljenima upravo između stranaka tog ugovora, zbog čega pridjev “prisilne” gubi na svojem značenju i snazi. Bitan element u razlikovanju “prisilnih” i “dobrovoljnih” arbitraža mora upravo biti u postojanju volje i saglasnosti stranaka da svoje sporove rešavaju baš pred sudom kojeg su sami izabrali ili potpisivanjem Ugovora pristali na nadležnost suda predloženog od druge strane. “Prisila” da se zbog nužnosti ili želje za potpisivanjem određenog ugovora ili drugog pravnog posla pristaje na arbitražu koju je predložila “jača strana” po mojem mišljenju ne čini takvu arbitražu “prisilnom”, baš zbog postojanja mogućnosti druge strane da se odupre takvoj prisili.
RAZVOJ ČITALAČKIH POTREBA UČENIKA OSNOVNIH ŠKOLA U DIGITALNOM SVETU
Authors: Cvetković Mona , Mijatović Marko
Published: February 2025

U savremenom obrazovnom sistemu, digitalna tehnologija značajno utiče na način na koji učenici osnovnih škola pristupaju čitanju i razvijaju svoje čitalačke navike. Ovaj rad istražuje kako digitalni alati i resursi oblikuju čitalačke potrebe i interesovanja učenika.
Razvoj čitalačkih potreba učenika u digitalnom svetu ukazuje na potrebu za balansiranjem između tradicionalnih i digitalnih formata čitanja. Preporučuje se integracija digitalnih resursa u obrazovne planove, uz naglasak na očuvanje dubokog čitanja i analitičkog razmišljanja. Takođe, potrebno je razvijati strategije za poboljšanje čitalačkih veština i navika u digitalnom okruženju.
Da bi se unapredio razvoj čitalačkih potreba, predlaže se unapređenje obrazovnih programa koji uključuju digitalne resurse, obuka nastavnika za efektivnu integraciju tehnologije u nastavu i pro- movisanje aktivnosti koje podstiču čitalački entuzijazam i duboko razumevanje teksta.

STRUČNO USAVRŠAVANJE NASTAVNIKA KAO KONTINUIRANA AKTIVNOST
Authors: Huseinagić Enes
Published: February 2025

Stručno usavršavanje nastavnika u posljednje vrijeme sve je aktuelnije - posebno zbog toga što škola kao vaspitno - obrazovna ustanova sve više ulazi u fazu kada je moguće da daje veći kvalitet nas- tavno - vaspitnog rada. To će se moći postići samo tada ako se obezbijedi i permanentno stručno usavršavanje nastavnika. Sve više postaje jasno da se povećanje efekta škole ne može ni zamisliti bez usavršavanja nastavnika, pošto nastavnik, ako, nije pripremljen i osposobljen da prihvata novine, u radu, može još kako usporiti poboljšanje rada škole bez obzira pa materijalnu bazu. Za uspjeh u stručnom usavršavanju osnovno je, naravno, da ono mora proisteći iz dubljeg uvjerenja i stava nastavnika da je i potrebno. Zahtjevi koji dolaze iz škola, od nastavnika, su sporadični, što je upravo razlog više da sadašnjom praksom stručnog usavršavanja ne možemo biti zadovoljni, pored ostalog i zato jer želimo da nam prosvjetni radnik ne postane konzervativan (to u prirodi njegova poziva nije, ali on takav praktično može biti), da ide u korak s vremenom (a za neke se, zašto da to ne kažemo, teško može reći da idu u korak s vremenom).

Authors: Firdaus Nefra , Swastiningsih Swastiningsih , Sumartono Sumartono , Sumartono Eddy , Intan Dyah Noor
Published: February 2025

This study investigates the efficacy and engagement of virtual reality (VR) as a tool for public speaking training. The primary objective is to qualitatively analyze the literature to understand how VR technology can enhance public speaking skills and increase user engagement compared to traditional training methods. The research employs a qualitative literature review methodology, synthesizing findings from academic articles, industry reports, case studies, and empirical studies to provide a comprehensive overview of the current state of knowledge in this field. The literature review methodology involves systematically collecting and analyzing scholarly sources that explore various aspects of VR in public speaking training. The study categorizes the literature into key themes, such as the effectiveness of VR in simulating real-life speaking scenarios, the psychological benefits of using VR for reducing anxiety, and the levels of user engagement and motivation in VR-based training programs. Thematic analysis is used to identify patterns and trends in how VR influences public speaking proficiency and participant engagement. The findings indicate that VR offers a highly immersive and interactive environment that can closely mimic real-life public speaking situations, providing users with valuable practice opportunities. Studies show that VR can significantly reduce public speaking anxiety by allowing users to repeatedly practice in a controlled, virtual setting. Additionally, VR-based training programs are found to be more engaging and motivating for users, leading to higher levels of participation and improved learning outcomes.

The research examined the relationship between teacher pedagogical content knowledge and practical skills competence as factors influencing students’ performance in Biology within the Abeokuta South Local Government Area of Ogun State. Employing a correlational research design, the study involved 240 respondents, specifically SSII biology students, who were selected through a multistage sampling technique. Data were gathered using the Teacher Pedagogical Content Knowledge and Competence in Practical Skills Rating Scale, which demonstrated reliability coefficients of 0.80 and 0.73, respectively. The analysis of the collected data utilized descriptive statistics and multiple regression techniques. The findings indicated a significant influence of the level of teacher pedagogical content knowledge and competence in practical skills on the academic performance of students. The findings also revealed that teachers’ competence in practical skills has a positive effect on students’ understanding of biological concepts and students’ performance in biology. In light of these results, the study recommends that educators should im-prove their pedagogical content knowledge and practical skills competence to improve students’ performance in Biology. Furthermore, teacher training programs should prioritize the development of robust content knowledge and practical skills in the field of Biology.

On sumsets of dissociated sets∗
Authors: D. Shkredov I.
Published: February 2025

In the paper, we are studying some properties of subsets \( Q \subseteq \Lambda_1 + \cdots + \Lambda_k \), where \( \Lambda_i \) are dissociated sets. The exact upper bound for the number of solutions of the following equation:
\[
q_1 + \cdots + q_p = q_{p+1} + \cdots + q_{2p}, \quad q_i \in Q \tag{1}
\]
in groups \( \mathbb{F}_2^n \) is found. Using our approach, we easily prove a recent result of J. Bourgain on sets of large exponential sums and obtain a tiny improvement of his theorem. Besides, an inverse problem is considered in the article. Let \( Q \) be a set belonging to a subset of two dissociated sets such that equation (1) has many solutions. We prove that in this case, a large proportion of \( Q \) is highly structured.
On the average profile of symmetric digital search trees

Published: February 2025

A digital search tree (DST) – one of the most fundamental data structures on words – is a digital tree in which keys (strings, words) are stored directly in (internal) nodes. The profile of a digital search tree is a parameter that counts the number of nodes at the same distance from the root. It is a function of the number of nodes and the distance from the root. Several tree parameters, such as height, size, depth, shortest path, and fill-up level, can be uniformly analyzed through the profile. In this note we analyze asymptotically the average profile for a symmetric digital search tree in which strings are generated by an unbiased memoryless source. We show that the average profile undergoes several phase transitions: initially it resembles a full tree until it starts growing algebraically with the number of nodes, and then it decays first algebraically, then exponentially, and finally quadratic exponentially. We derive these results by a combinational of analytic techniques, such as the saddle point method.

On Fuglede's conjecture for three intervals
Authors:   Indian Institute of Technology Kanpur, India, Bose Debashish
Published: February 2025

In this paper, we prove the Tiling implies Spectral part of Fuglede’s cojecture for the three interval case. Then we prove the converse Spectral implies Tiling in the case of three equal intervals and also in the case where the intervals have lengths 1/2, 1/4, 1/4. Next, we consider a set Ω ⊂ R, which is a union of n intervals. If Ω is a spectral set, we prove a structure theorem for the spectrum provided the spectrum is assumed to be contained in some lattice. The method of this proof has some implications on the Spectral implies Tiling part of Fuglede’s conjecture for three intervals. In the final step in the proof, we need a symbolic computation using Mathematica. Finally with one additional assumption we can conclude that the Spectral implies Tiling holds in this case.
Geometric construction of metaplectic covers of \(GL_n\) in characteristic zero
Authors: Hill Richard
Published: February 2025

This paper presents a new construction of the \( m \)-fold metaplectic cover of \( \mathrm{GL}_n \) over an algebraic number field \( k \), where \( k \) contains a primitive \( m \)-th root of unity. A 2-cocycle on \( \mathrm{GL}_n(\mathbb{A}) \) representing this extension is given, and the splitting of the cocycle on \( \mathrm{GL}_n(k) \) is found explicitly. The cocycle is smooth at almost all places of \( k \). As a consequence, a formula for the Kubota symbol on \( \mathrm{SL}_n \) is obtained. The construction of the paper requires neither class field theory nor algebraic \( K \)-theory but relies instead on naive techniques from the geometry of numbers introduced by W. Habicht and T. Kubota. The power reciprocity law for a number field is obtained as a corollary.
A probabalistic interpretation of a sequence related to Narayana polynomials

A sequence of coefficients appearing in a recurrence for the Narayana polynomials is generalized. The coefficients are given a probabilistic interpretation in terms of beta distributed random variables. The recurrence established by M. Lasalle is then obtained from a classical convolution identity. Some arithmetical properties of the generalized coefficients are also established.
Euler-Frobenius numbers and rounding
Authors:   DEPARTMENT OF MATHEMATICS, UPPSALA UNIVERSITY, PO BOX 480, SE-751 06 UPPSALA, SWEDEN, Janson Svante
Published: February 2025

We study the Euler–Frobenius numbers, a generalization of the Eulerian numbers, and the probability distribution obtained by normalizing them. This distribution can be obtained by rounding a sum of independent uniform random variables; this is more or less implicit in various results and we try to explain this and various connections to other areas of mathematics, such as spline theory.
The mean, variance and (some) higher cumulants of the distribution are calculated. Asymptotic results are given. We include a couple of applications to rounding errors and election methods.
Ergodic-theoretic implementations of the Roth density-increment argument
Authors:   COURANT INSTITUTE, NEW YORK UNIVERSITY, NEW YORK, NY 10012, USA, Austin Tim
Published: February 2025

We exhibit proofs of Furstenberg’s Multiple Recurrence Theorem and of a special case of Furstenberg and Katznelson’s multidimensional version of this theorem, using an analog of the density-increment argument of Roth and Gowers. The second of these results requires also an analog of some recent finitary work by Shkredov.

Many proofs of these multiple recurrence theorems are already known. However, the approach of this paper sheds some further light on the well-known heuristic correspondence between the ergodic-theoretic and combinatorial aspects of multiple recurrence and Szemeredi’s Theorem. Focusing on the density- increment strategy highlights several close points of connection between these settings.

The transition to college life often requires students to face various challenges and significant changes in their lives. Individuals who have a high level of subjective well-being tend to have the ability to assess life events in a more positive way. This study aims to analyze the relationship between religiosity and grit with subjective well-being in Psychology students at Universitas Islam 45 Bekasi. This study used a quantitative method involving 134 respondents who were determined using a non-probability sampling technique with a consecutive sampling method. Data collection was carried out using three psychological scales, namely the religiosity scale, the grit scale, and the subjective well-being scale, and the data analysis techniques applied included assumption tests using normality and linearity tests, as well as hypothesis tests using correlation tests and multiple linear regression analysis. The results showed that there was a significant positive relationship between religiosity and subjective well-being (r = 0.546, p <0.005), as well as between grit and subjective well-being (r = 0.738, p <0.005). Multiple linear regression analysis revealed that religiosity and grit together could predict 57.6% of the variance in subjective well-being (R2 = 0.576), (F(2,121) = 89.037), (p < 0.001), while the remaining 42.4% was influenced by other factors.

Middle adulthood is a critical stage in life characterized by significant transformations in physical, psychological, and social aspects. During this period, individuals often face a decline in certain physical and mental capacities while also having opportunities to achieve greater levels of maturity. Challenges such as health issues, changing social roles, and increasing family responsibilities are commonly encountered. The complexity of fulfilling physical, emotional, and social needs increases, significantly impacting overall well-being. Addressing these needs involves various efforts, including maintaining good health, managing stress, and fostering meaningful social connections. Support from the surrounding environment plays a crucial role in helping individuals meet these needs. Therefore, a deep understanding of the challenges faced during middle adulthood is essential for improving their quality of life. The ability to manage physical and psychological changes while sustaining positive social relationships is key to achieving a balanced and fulfilling life during this phase.

O presente estudo teve como objetivo investigar a neurite óptica em crianças, uma condição inflamatória do nervo óptico que pode resultar em perda de visão e está frequentemente associada a doenças desmielinizantes como a esclerose múltipla (EM). Apesar de ser uma condição reconhecida, a literatura disponível sobre a apresentação clínica, fatores prognósticos e taxa de conversão para EM em crianças é limitada, levando à necessidade de uma revisão sistemática que possa esclarecer as diferenças em relação à população adulta. O problema de pesquisa que este estudo se propôs a explorar é a falta de compreensão das particularidades da neurite óptica pediátrica e sua relação com a progressão para EM, uma vez que as taxas de conversão observadas em crianças são significativamente menores do que em adultos. A metodologia aplicada envolveu uma revisão sistemática da literatura, onde foi realizada a busca e seleção em bases de dados reconhecidas, como PubMed e SciELO, utilizando critérios de inclusão e exclusão rigorosos para garantir que os estudos selecionados fossem relevantes e de alta qualidade. A análise dos dados foi estruturada por meio de uma matriz que permitiu coletar informações essenciais sobre cada estudo, como autor, ano de publicação, objetivos, características da amostra e principais achados. Os resultados da revisão revelaram que a neurite óptica em crianças, embora compartilhe algumas características com a forma adulta, apresenta padrões distintos de apresentação clínica, sendo a dor ocular menos prevalente e a recuperação visual geralmente mais favorável nas crianças. Na maioria dos casos analisados, a utilização de corticosteroides resultou em recuperação acentuada da acuidade visual, evidenciando a eficácia do tratamento inicial. Além disso, a presença de lesões visíveis por ressonância magnética foi associada a um risco maior de conversão para EM, reforçando a importância do diagnóstico por imagem na avaliação prognóstica. O estudo também destacou a discrepância nas taxas de conversão para EM entre diferentes populações, observando que crianças asiáticas apresentaram taxas muito mais baixas, sugerindo a atuação de fatores genéticos e ambientais. Contudo, o estudo possui limitações significativas, uma vez que os dados foram extraídos de literatura existente, o que pode introduzir viés de seleção e limita a generalização dos achados.

La Constitution est la base même de la vie politique et sociale d’une nation dont elle régule l’existence individuelle et collective, privée et institutionnelle. Son respect tant par les gouvernants que les gouvernés apparaît dès lors comme une exigence fondamentale pour le bon fonctionnement des institutions et de la vie collective. Ce respect dépend lui-même d’une vive conscience citoyenne, voire d’un patriotisme sincère qui doivent être façonnés ou renforcés à travers une pédagogie appropriée. Un défi pour la RDC.

México es un importante exportador agrícola, con productos como el aguacate, tomate, y las berries (fresas, frambuesas y arándanos). En 2023, las exportaciones agrícolas alcanzaron más de 46 mil millones de dólares, posicionando a México como un proveedor clave de alimentos para mercados como el estadounidense (Secretaria de Agricultura y Desarrollo Rural [SADER], 2023).
Los tipos de producción que predominan en el país son: producción de agricultura de subsistencia, producción comercial y producción orgánica y sustentable. La agricultura de subsistencia predomina en zonas rurales y se centra en cultivos básicos como el maíz y el frijol. Este tipo de agricultura suele tener rendimientos bajos y es realizada principalmente por pequeños productores (Organización de las Naciones Unidas para la Alimentación y la Agricultura (FAO, 2021).

Los indicadores de envejecimiento poblacional a nivel mundial han presentado un alza en los últimos años, generando un fenómeno de envejecimiento exponencial de la población. En 2018 con una esperanza de vida superior a los 60 años, 125 millones de personas tenían 80 años o más (OMS, 2018). A esta realidad se suma el hecho de que los sistemas de seguridad social en muchos países han abandonado los principios que los sustentan, como el principio de solidaridad y el de integralidad. De forma tal que ahora es necesario un ahorro adicional a los sistemas de seguridad social para tener una pensión por jubilación, que permita a las personas tener una calidad de vida similar a la que tenían antes de retirarse (Atlatenco, et al., 2021).
En México, la proyección de la evolución demográfica ha demostrado que la vida media de los mexicanos aumentará de los 70 a los 79 años entre 1990 y 2050 (SEGOB, 2018).
