The Influence of Saussure’s Language Theory on English Vocabulary Teaching
Authors: Li Wenqi
Published: September 2024

Many famous scholars have put forward their opinions on the nature of language. Among them, the most famous are Saussure’s dichotomy and Pierce’s trichotomy. Vocabulary learning plays a very important role in foreign language learning. Therefore, many scholars continue to carry out research and experiments on vocabulary learning and they try to find more effective and practical ways to help English learners remember words better and faster. Saussure put forward the viewpoint of arbitrariness of language signs. He believed that the first characteristic of language signs was their arbitrariness, that is, there was no natural and necessary essential relationship between the sound and meaning of language signs. Saussure’s discussion on the principle of arbitrariness points out two main points of the principle of arbitrariness. First, it refers to the relationship between the signifier and the signified. He points out that the connection between the signifier and the signified is arbitrary. Beyond this scope, the principle will not apply. Saussure regards language as a purely psychological phenomenon. He believes that the signifier of language symbols is the sound image, and the signifier is the concept. Second, it refers to the "natural connection" between the two, that is, it cannot be seen from the physiological or physical properties of a certain language that it should be combined with a certain conceptual meaning into a language symbol. On the contrary, we can not see the reason that a certain concept combines with a certain voice to form a language symbol from its meaning characteristics. This paper attempts to apply Saussure’s language theory to daily English vocabulary teaching in order to find a simple, feasible and effective way to remember English words and phrases.

How important of the effect of temperature on the efficiency of solar photovoltaic cells?
Authors: Xu Wenxi
Published: September 2024

The most direct effect on the efficiency is the temperature of solar modules. I discussed the reasons why the temperature of modules can affect the efficiency of solar cells and the explanation of how can we improve the solar system to decrease the influence of high cell temperature. The scarcity of traditional energy increases, so the scale of use of renewable energy increases. The efficiency of the energy-generating system is the most important factor that users consider. The extent of change in the temperature of solar modules is the highest, so the temperature of solar modules can cause an influential decrease in the efficiency of energy generation. I have used the data based on experiments set by other authors to illustrate the extent of influences of four main variables on the efficiency of the solar cells. I used of the properties of air and water to design two schemes to minimize the effects of high temperatures of solar cells. I compared the change in efficiency under one unit increase in variables. All of the data used in calculating or referring are from different experiments done by different authors. I connected the results with real conditions to determine the most influential variables-temperature of modules. Based on the theoretical result, the shading effect has the largest value of decrease in efficiency, so the effects of shading are considered by manufacturers a lot. Based on real-life situations, the scale of change in the temperature of modules and the actual temperature of modules are always higher than the standard operating temperature, 25, so the temperature of modules is the most influential variable. Monocrystalline silicon solar cells have different extents of influence of variables to polycrystalline silicon solar cells, these two types of solar cells are suitable to be installed in regions with low humidity. However polycrystalline solar cells are more sensitive to increases in the temperature of modules, so they need to pay more attention and avoid the effects of high temperature of modules.

ANALIZA EKONOMSKE (NE)RAVNOTEŽE PLATNOG BILANSA REPUBLIKE SRBIJE U PERIODU 2007-2023.
Authors: Sekulić Aleksandar
Published: September 2024

Rad je posvećen analizi ekonomske ravnoteže platnog bilansa na primeru Republike Srbije od 2007. do 2023. godine. Srbija, kao mala i otvorena privreda, beleži perzistentan deficit u tekućem delu platnog bilansa tokom čitavog perioda analize usled značajne zavisnosti od uvoza roba i, posledično, visokog deficita robne razmene, kao i deficita na računu primarnog dohotka. Najveći deficit u ovom delu platnog bilansa ostvaren je za vreme Globalne finansijske krize 2007/2008. godine, koji se potom smanjuje sve do izbijanja Pandemijske krize 2020. i Geopolitičke krize 2022, kada dolazi do blagog pogoršanja. Sa druge strane, suficit u razmeni usluga i stabilan priliv u vidu doznaka iz inostranstva, usled migracija stanovništva mahom u zapadnoevropske zemlje, ublažavaju deficitni saldo tekućeg računa. U Republici Srbiji se godinama unazad beleži trend rasta neto priliva po osnovu stranih direktnih investicija u kapitalno-finansijskom delu platnog bilansa, koji od 2015. godine uspešno pokriva deficitni saldo tekućeg računa. Shodno deficitnoj poziciji tekućeg računa i suficitnoj poziciji kapitalno-finansijskog računa, zaključujemo da je bazični bilans pozitivan, te je izbegnut rizični scenario pokrivanja deficitnih pozicija kratkoročnim kapitalom i deviznim rezervama. Usmeravanje poluga ekonomske politike ka ublažavanju hronično deficitne pozicije tekućeg računa ostaje prioritetan cilj, imajući u vidu vezu platnobilansne pozicije sa deviznim tržištem, deviznim kursem, inflacijom i realnom ekonomijom.

A self-balancing two-wheel Segway is a multivariable, nonlinear, coupled and unstable personal transport that is among the benchmarks of under-actuated systems to test different control schemes. The proper operation of the system needs stable and robust controllers for the balancing and direction of the Segway. Stable and robust performance of such systems can be achieved using adaptive, optimal and non-linear control schemes. A conventional sliding mode controller is a nonlinear controller, considered a robust controller except for the chattering problem that can be solved using higher order sliding mode controllers such as a supper twisted sliding mode controller (STSMC). In this research, STSMC is proposed for balancing and PID controller for direction control of a self-balancing Segway. To solve the impacts of design technique, skill, and experience of the designer on the control schemes, controllers are tuned using metaheuristic optimization algorithms, namely Grey wolf algorithm (GWO), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) technique. The overall system has been implemented in MATLAB/Simulink, and performance evaluations have been executed for the time domain specifications of settling and rise times as comparison criteria for the Segway operating conditions of variable driver mass and tilt angles. The results show relatively quick responses - for initial pitch angel of 0.3 rad, and initial yaw angle of 0.1 rad – of GWO-STSMC and GWO-PID controllers. For variable driver mass and constant initial tilt angles, the pitch response is found to be less sensitive to the increase in mass of the driver for GWO-STSMC, while the yaw angle response shows a slight sensitivity decrease for GWO-PID controller. For variable initial tilt angles and constant mass of the drive, both GWO-STSMC and GWO-PID controllers show the capability of tracking the reference pitch and yaw angles.
Connectivity of lions (Panthera leo) across a pastoralist landscape : coexistence, conflict, and collective action for lion conservation in Ngorongoro, Tanzania
Authors: Jansson Ingela
Published: September 2024

This thesis investigates human-lion coexistence and connectivity in the Ngorongoro Conservation Area (NCA). By combining ecological, genetic, and socio-ecological perspectives, it identifies key challenges and opportunities in managing shared landscapes between people and wildlife. The findings show that lions avoid humans on the landscape, but when natural prey is scarce, they may prey on livestock, causing economic losses and prompting retaliatory killings. While lions disperse across the landscape, genetic analysis reveals limited exchange between populations, with the Crater lions showing low genetic diversity, inbreeding, and restricted gene flow, threatening long-term resilience. This isolation is exacerbated by the dominance of Crater-born males. The NCA is at a critical crossroads where sustainable coexistence between humans and lions is still achievable. With pressures from climate change, population growth, and resource demands, this requires a balanced approach that fosters community-driven initiatives, effective conflict management, and recognizes that the futures of both lions and people are inherently connected.

Este artigo tem como objetivo utilizar métodos de simulação para analisar o processo de produção de bobinas para transformadores de uma empresa situada no interior do Estado de São Paulo. Foi utilizado o software Arena para realizar a simulação computacional do processo na empresa em questão, a fim de identificar os gargalos. Os dados foram coletados e relacionados ao tempo de produção das bobinas de potências de 75kVA, 225kVA e 300kVA. Através desses dados foi possível criar um fluxograma referente ao cenário atual da empresa. Os resultados mostraram que há gargalos nos processos de produção das três potências de bobinas. Após a constatação, foram propostas algumas sugestões de melhorias; a partir delas, realizamos uma nova simulação adequando os dados às mudanças propostas e verificamos a eficiência e viabilidade. A metodologia utilizada foi a de pesquisas em artigos científicos, livros, revistas, sites acadêmicos e teve como objetivo analisar o processo produtivo de transformadores por meio da simulação computacional com o software Arena. Através do software Arena deixamos a simulação próxima da realidade da produção, facilitando a visualização dos gargalos e a tomada de decisão.

Os resultados destacam a alta taxa de tratamento fitossanitário no Brasil, demonstrando a adesão do país a práticas rigorosas. Além disso, destaca-se que a China é o maior destino das exportações de soja brasileira, exigindo tratamento fitossanitário, enfatizando a importância dessa prática para atender a requisitos específicos de mercados-chave. Em resumo, o tratamento fitossanitário é um pilar fundamental nas exportações de soja do Brasil. Para manter sua posição de liderança no mercado global, o Brasil deve continuar aprimorando suas práticas de tratamento fitossanitário, acompanhando as demandas dos mercados internacionais e mantendo seu compromisso com a qualidade e segurança de seus produtos agrícolas. A posição do Brasil no comércio global de soja é vital não apenas para sua economia, mas também para a segurança alimentar global e o desenvolvimento sustentável.
Tracking the course of preclinical Alzheimer’s disease Within a genetically Identical and cognitively Normal older twin Sample
Authors:   , Tomassen Jori
Published: September 2024

The general aim of this thesis was to investigate early pathophysiology of Alzheimer’s disease (AD) in cognitively unimpaired older individuals (including monozygotic twin-pairs) and investigate the associations of amyloid-β and tau biomarkers (as measured with PET and CSF), APOE genotype and AD-PRS with cognitive decline. We further studied the relative contribution of genetic and environmental influences to AD biomarkers, cognitive decline and to the relation between these markers using a monozygotic twin design. The key findings of this thesis are listed below:
- Monozygotic twin-pair correlations show that environmental factors substantially influence the onset of amyloid-β production and aggregation markers, tau markers and cognition.
- Increased amyloid-β production, as assessed by CSF BACE-1, is a very early feature of AD pathophysiology.
- Cognitively unimpaired older individuals who have abnormal CSF amyloid-β and tau markers show steeper decline in memory and language functioning and these associations are in part determined by the same underlying genetic factors.
- A high AD-PRS and APOE genotype are associated with amyloid-β positivity and cognitive decline over time.
- The association of APOE genotype on cognitive decline was dependent on amyloid-β positivity, whereas a high AD-PRS explained variance in cognitive decline independently of APOE genotype and amyloid-β positivity.
- Discordant amyloid-β negative twins show higher conversion risk to an amyloid-β positive status over time compared to concordant amyloid-β negative twins.
- Twin-pairs who are further along the AD continuum, based on the longitudinal amyloid-β PET twin concordance model, were generally older, more often APOE ε4 allele carriers, showed highest levels of tau and steepest decline in memory performance.
- Associations between amyloid-β, tau, neurodegeneration and cognition are unbiased by (genetic) confounding.
- In line with the amyloid cascade hypothesis, effects of amyloid-β on neurodegeneration and cognitive decline are fully mediated by tau.

This thesis shows that besides biomarkers for amyloid-β and tau, also genetic determinants of AD can be used to identify cognitively unimpaired individuals at risk of cognitive decline. The very first cognitive changes in AD are found in the memory and language domains. The relationship between biomarkers and cognitive decline is robust, since different modalities of biomarkers produced similar results. Finally, the onset and development of AD underlies a complex interplay of genetic and environmental influences, where environmental factors seem to influence the onset of amyloid-β aggregation. This thesis contributed to early identification of AD pathology and highlights the important role of biomarkers for diagnosis in cognitively unimpaired populations.
