Dickens's Mudfog
Authors: Tambling Jeremy
Published: June 2024

Abstract: This article has three intentions. It starts with the name "Mudfog" as this appears in Dickens, and as the combination of mud and fog – why these? – runs throughout Dickens's prose and his settings, and his interests. It gives particular attention here to Bleak House and Little Dorrit and Great Expectations . Second, it is interested in thinking of mud and fog not as "symbols," but as modes of thinking (definable as allegorical), and here it pursues Dickens's reading of Shakespeare by looking at the uses of mud and fog as they accumulate from Shakespeare's plays. It attempts to read Dickens not as merely drawing on Shakespeare but as enabling a reading of Shakespeare in turn – here discussion of Hamlet becomes crucial for a reading of Bleak House .

ABSTRACT: Tahir Hamut Izgil's recent memoir, Waiting to Be Arrested at Night, brings to life a cast of poets and intellectuals who used to meet under the cover of darkness, against the backdrop of mass detentions in Ürümqi, the capital of Xinjiang province. In his 2018 poem "Somewhere Else," Izgil, who escaped China, writes with the exile's keen longing: "Of course / I too can only stare / for a moment into the distance."
AMLO's Final Act
Authors: Beck Humberto , Iber Patrick
Published: June 2024

ABSTRACT: During his five years in office, Andrés Manuel López Obrador, the president of Mexico, has rarely left the country. But in September 2023, AMLO, as he is commonly known, made a trip to Colombia and Chile, Latin American countries that are also currently governed by the left. In Colombia, AMLO met with President Gustavo Petro and participated in the Latin American and Caribbean Conference on Drugs, where Petro called for an end to the failed strategy of "viewing drugs as a military problem and not as a health problem for society." AMLO said that preserving family unity and combating poverty are essential to that fight.

Josephine Butler in Paris: Sex and Race in the Early Campaign to Abolish Regulated Prostitution, 1870–1880
Authors: Ross Andrew Israel
Published: June 2024

Abstract: During the 1870s, Josephine Butler brought her campaign against the Contagious Diseases Acts to Paris, the birthplace of regulated prostitution. While in Paris, Butler and her allies refined their arguments against regulated prostitution using the Paris morals police as their primary example. As they did so, these activists came to increasingly radical conclusions about the danger of police power more generally. However, the French context not only pushed Butler toward greater skepticism regarding the police but also to an increasingly racialized understanding of that danger. In order to play to French natalist fears, Butler argued that reducing police power over female prostitutes was necessary to preserve European racial health.
Evolution of Servant Laws in the Habsburg Empire
Authors: Natarajan Ambika
Published: June 2024

Abstract: The evolution of the legal status of servants in Europe is a sparsely researched field. Concentrating on the case of the Habsburg Empire since the sixteenth century, this article emphasizes the importance of considering the evolution of servant laws in discussions about protective legislation for servants. This article argues that the issue of granting rights and protections to servants has always pivoted on the definition of their status in society. Since servants occupied an intermediary position on the freedom scale, the control of people who occupied this position—not slave, yet not entirely free—has been a point of concern for several centuries. Research on how servant laws have historically contributed to the survival of paternalistic attitudes that cripple the rights and freedoms of servants is essential to understanding the more complex parameters of race, gender, and class that govern the lives of this category of predominantly migrant, minority, and female labor.
“It’s an Old White Boys’ Club:” Faculty of Color’s Perceptions of Policy Engagement
Authors: Gándara Denisa , Kim Victoria , Kaur Navdeep , Jones Michaela , Ramirez Catherine
Published: June 2024

Scholars of color remain underrepresented in policymaking contexts, and the absence of their expertise in policy processes can have significant consequences
for society. In this study, we examine motivations for and perceived barriers to engagement in public policymaking among faculty of color. Using an institutional logics framework and interviews with 20 tenure-stream faculty of color at 20 research universities, we identify three main themes that elucidate their perceptions of public policy engagement: (1) the network-driven, racialized nature of public policymaking spaces; (2) communal motivations and perceived benefits of public policy engagement; and (3) the double-edged sword of engaging with public policymaking.
Terahertz dependence on the laser phase and wavelength in two-color circularly polarized laser fields
Authors: Yang Cai-Xia , Zhang Lei , Jiao Zhi-Hong , Zhao Song-Feng , Wang Guo-Li
Published: June 2024

Two-color circularly polarized laser fields with the same helicity (CP-S) are an appealing type of driving field that is essential for generating strong terahertz (THz) radiation. In this work, we theoretically investigate how the phase delay between two components in a CP-S field and their wavelength affect THz radiation yield with a photocurrent model. Simulations show that, as the laser wavelength increases, the THz yield becomes more and more phase dependent, which is maximized when the relative phase is 0 and minimized when the relative phase is π. Such a phase dependence is completely different from the commonly used two-color linearly polarized laser pulse with parallel polarizations (LP-P). In addition, in the CP-S field, the THz radiation energy may exhibit a wavelength scaling λ
α
(λ is the fundamental wavelength) with a bigger exponent than in the LP-P field at longer wavelengths. Our findings have important implications for the generation of powerful THz radiation via femtosecond laser interaction with gasses.
Entropy analysis on chaos excited through destabilization of semiconductor lasers at period-one nonlinear dynamics for physical random number generation

Published: June 2024

This study analyzes entropy of broadband chaos excited in a semiconductor laser subject to intensity-modulated optical injection for random number generation with guaranteed unpredictability. It is identified that the flattening of spectral profile around the laser relaxation resonance blurs the periodicity it brings, and thus leads to a high entropy value and a high random number generation rate. The effect of measurement device noise on entropy suggests that both the power of chaos needs to be kept at a level to achieve an adequate signal-to-noise ratio, 24 dB or more, and the entropy contribution of the measurement device noise is excluded in order to assert entropy that can be extracted solely from the intrinsic property of chaos. The effect of data sampling rate on entropy shows that entropy reaches its maximum at the Nyquist rate, which is two times the standard bandwidth of chaos, and the rate of change in entropy is much slower than that in sampling rate as the sampling rate varies, which leads to the dominance of the sampling rate, not entropy, in determining the random number generation rate. It is highly likely that modest oversampling (i.e., a sampling rate modestly higher than the Nyquist rate) gives rise to a higher random number generation rate while entropy slightly decreases.

Published: June 2024

Polycrystalline silicon-germanium (SiGe) core fibers offer great potential as flexible platforms for microscale optoelectronic and nonlinear optical devices. Compared to silicon (Si) core fibers, the SiGe material provides the potential for higher nonlinear coefficients, extended mid-infrared wavelength coverage, and a means to tune the bandgap and index of refraction by varying the Ge composition. Here, SiGe core fibers (10 at% Ge) were fabricated using the molten core drawing method, followed by CO2 laser irradiation to improve the homogeneity of the core. The transmission properties of the fibers were further optimized using a fiber tapering method to tailor the core diameter and re-grow the crystal grains. The resulting tapered SiGe fiber exhibited an average linear loss of ∼3 dB cm−1 across the wavelength range 1.5 − 2.5 µm, allowing for nonlinear optical characterization of this new fiber type. Measurements of the nonlinear figure of merit demonstrate the potential for higher nonlinear performance compared to the pure Si core fibers, particularly for wavelengths >2 µm, indicating that the SiGe fiber platform could open up new opportunities for mid-infrared nonlinear photonics.

Published: June 2024

The application of a liquid crystal (LC) in displays has driven the development of novel LC elements. In this Letter, polarization variable line-space (PVLS) gratings based on photoalignment are fabricated, and their variable-spacing properties are derived using the vector diffraction theory. Both transmissive and reflective PVLS gratings are fabricated to validate the correctness of the derivation. Experimental results indicate that PVLS gratings have a wider wavelength response bandwidth than that of polarization volume grating (PVG). PVLS gratings have angle selectivity, and a large incident angle causes wavelength blueshift. Additionally, the relationship between wavelength and focal length indicates its anomalous dispersion as a diffractive optical element. These results of photoalignment-based PVLS gratings provide valuable insights for the advancement of displays and have the potential to improve visual experiences.
Stress, reflectance, and stability of Ru/Be multilayer coatings with Mo interlayers near the 11 nm wavelength
Authors: Smertin Ruslan , Chkhalo Nikolai , Garakhin Sergey , Polkovnikov Vladimir , Zuev Sergey
Published: June 2024

The stress, reflectance, and temporal stability of Ru/Be multilayer mirrors, both with and without Mo interlayers, were studied. A Ru/Be MLM was found to have zero stress at a Ru layer thickness-to-period ratio of γ ∼ 0.4. By adding Mo interlayers to both interfaces, it is possible to achieve a record-high reflectance (R > 71%) at a wavelength close to 11 nm while maintaining near-zero stress levels. A Ru/Be MLM with Mo interlayers at both interfaces also demonstrates high temporal reflectance stability. Ru/Be MLMs may be of interest for the next-generation projection lithography at a wavelength of 11.2 nm.

The German validation of the Body Perception Questionnaire-Short Form (BPQ-SF) and its relation to current self-report measures of interoception

Published: June 2024

The Body Perception Questionnaire-Short Form (BPQ-SF) is one of the most used questionnaires to assess interoception. Although the BPQ-SF has been translated into different languages, there is no validated German questionnaire adaptation so far. Furthermore, empirical evidence outlining how the BPQ-SF relates to novel theories of interoception that distinguish between different facets, such as attention and accuracy, is still missing. The current study therefore aims at (1) validating the German version of BPQ-SF (with data from three different sites, Ntotal = 1292) and (2) relating it to the constructs of interoceptive accuracy and attention. In line with the original validation of the BPQ-SF, in the German version, an adequate three-factor structure and good internal consistency were found. However, reliability indexes varied between good, for the supra-and subdiaphragmatic scales and poor, for the body awareness scale. The three scales of the BPQ-SF showed significant associations with interoceptive measures and, more importantly, were related to both interoceptive accuracy and attention, suggesting that they mirror a mixture of both constructs. Finally, in relation to measures of psychopathology, the supra-and subdiaphragmatic (but not the body awareness) scales were positively related to alexythimic, anxious, and depressive tendencies. These findings provide evidence for the usability of the German version of the BPQ-SF and further shed light on the heterogeneity of the existing self-report measures of interoception.
Effectiveness and residual activity of four common insecticides used in the Mississippi Delta to control tarnished plant bugs in cotton
Authors: Portilla Maribel , Little Nathan , Allen Clint , Zhu Yu Cheng
Published: June 2024

The tarnished plant bug, (TPB) Lygus lineolaris Palisot de Beauvois (Hemiptera: Miridae) is a key pest of cotton in the midsouth region and some areas of the eastern United States. Its control methods have been solely based on chemical insecticides which has contributed to insecticidal resistance and shortened residual periods for control of this insect pest. This study was conducted over a two-year period and examined the efficacy and residual effect of four commercial insecticides including lambda-cyhalothrin (pyrethroid), acephate (organophosphate), imidacloprid (neonicotinoid), and sulfoxaflor (sulfoxamine). The effectiveness and residual effects of these insecticides were determined by application on cotton field plots on four different dates during each season using three different concentrations (high: highest labeled commercial dose (CD), medium: 1/10 of the CD, low: 1/100 of the CD) on field cotton plots. Four groups of cotton leaves were randomly pulled from each treated plot and control 0-, 2-, 4-, 7-, and 9-days post treatment (DPT) and exposed to a lab colony of TPB adults. One extra leaf sample/ plot/ spray /DPT interval (0-2-4-7-9-11) during 2016 was randomly collected from the high concentration plots and sent to Mississippi State Chemical Laboratory for residual analysis. Mortality of TPB adults was greatest for those placed on leaves sprayed with the organophosphate insecticide with mortalities (%) of 81.7±23.4 and 63.3±28.8 (SE) 1-day after exposure (DAE) on leaves 0-DPT with the high concentration for 2016 and 2017, respectively, reaching 94.5±9.5 and 95.4±7.6 6-DAE each year. Mortality to all insecticides continued until 9 and 4-DPT for high and medium concentrations, respectively. However, organophosphate (39.4±28.6) and pyrethroid (24.4±9.9) exhibited higher mortality than sulfoxamine (10.6±6.6) and the neonicotinoid (4.0±1.5) 7-DAE on 9-DPT leaves with the high concentration. Based on our results using the current assay procedure, TPB adults were significantly more susceptible to contact than systemic insecticides and due to its residual effect, organophosphate could kill over 80% of the TPB population 7-DPT.

Published: June 2024

Approximately 62,000 Zambian children are living with HIV. HIV care and treatment is generally more limited in rural areas, where a heavy reliance on rain-fed subsistence agriculture also places households at risk of food and water insecurity. We nested a mixed methods study with an explanatory sequential design in a clinical cohort of children and adolescents living with HIV (CHIV) in rural Zambia. We used validated questionnaires to assess household food and water insecurity and examined associations between indicators derived from those scales, household characteristics, and HIV treatment adherence and outcomes using log-binomial regression. We identified caregivers and older CHIV from food insecure households for in-depth interviews. Of 186 participants completing assessments, 72% lived in moderately or severely food insecure households and 2% in water insecure households. Food insecurity was more prevalent in households of lower socioeconomic status (80% vs. 59% for higher scores; p = 0.02) and where caregivers had completed primary (79%) vs. secondary school or higher (62%; p = 0.01). No other characteristics or outcomes were associated with food insecurity. Parents limited both the quality and quantity of foods they consumed to ensure food availability for their CHIV. Coping strategies included taking on piecework or gathering wild foods; livestock ownership was a potential buffer. Accessing sufficient clean water was less of a concern. During periods of drought or service interruption, participants travelled further for drinking water and accessed water for other purposes from alternative sources or reduced water use. Community contributions afforded some protection against service interruptions. Overall, while food insecurity was prevalent, strategies used by parents may have protected children from a measurable impact on HIV care or treatment outcomes. Reinforcing social protection programs by integrating livestock ownership and strengthening water infrastructure may further protect CHIV in the case of more extreme food or water system shocks.
Validation of an improved questionnaire assessing the social cognitive constructs of the Health Action Process Approach among parents regarding brushing their children’s teeth
Authors: van Nes Karin Alexandra , Loveren Cor van , Aartman Irene Helena Adriana
Published: June 2024

Objective

The Health Action Process Approach (HAPA) describes social cognitive constructs related to behaviour change. A validated questionnaire is needed to measure these constructs in paediatric dentistry. The aim of this study was to improve an existing HAPA-based questionnaire for parents regarding brushing their children’s teeth and to assess its validity and reliability in a population of parents of high caries risk children.

Methods

Parents of high caries risk children of 3–10 years filled out the adjusted HAPA-based questionnaire. Mokken scale analysis, graded response model analyses, factor analyses and reliability analyses were performed according to the protocol of Dima. Discriminant validity was assessed by comparing the mean scores of the HAPA constructs between two groups of participants, based on different levels of caries experience, brushing frequency and education level of the mother.

Results

The Mokken scale analysis and factor analyses indicated a multidimensional eight factor scale. The graded response model did not fit our data. The subscale action control could be identified as a two-factor subscale. Reliability indices from the Dima protocol varied, for instance Cronbach alpha ranged from 0.73 to 0.96. The constructs coping self-efficacy, action planning and action control discriminated between brushing frequencies.

Conclusions

The adjusted HAPA-based questionnaire is an improved, valid and reliable instrument that could be used to evaluate HAPA-based interventions to improve children’s oral health.
Mother-infant interaction characteristics associate with infant falling reactivity and child peer problems at pre-school age
Authors: Rigato Silvia , Vrticka Pascal , Stets Manuela , Holmboe Karla
Published: June 2024

This longitudinal study investigated the associations between mother-infant interaction characteristics at 9 months of age, maternal mental health, infant temperament in the first year postpartum, and child behaviour at 3 years of age. The infants (N = 54, 22 females) mainly had White British ethnic backgrounds (85.7%). Results showed that i) mother-infant dyadic affective mutuality positively correlated with infant falling reactivity, suggesting that better infant regulatory skills are associated with the dyad’s ability to share and understand each other’s emotions; and ii) maternal respect for infant autonomy predicted fewer child peer problems at 3 years of age, suggesting that maternal respect for the validity of the infant’s individuality promotes better social and emotional development in early childhood.
Novel insights into immune stress markers associated with myxosporeans gill infection in Nile tilapia (molecular and immunohistochemical studies)

Published: June 2024

Nile tilapia (Oreochromis niloticus) is valued in aquaculture because of its quick development and ability to thrive in various environments. Myxosporeans are among the fish parasites that affect fish productivity, as they impact fish growth and reproduction, resulting in large fish deaths in farms and hatcheries. This study has been focused on morpho-molecular identification for the myxosporean parasites infecting Nile tilapia from three governorates in Egypt and assessment of gene expression of different cytokines (Interleukin-1βeta (IL-1β), major histocompatibility complex class II (MHC-II), and clusters of differentiation 4 (CD-4) and 8 (CD-8)) in tissues. Additionally, this work aimed to correlate the developed histopathological alterations and inflammatory reactions in gills with immunohistochemical expression of inducible nitric oxide synthase (iNOS) and tumor necrosis factor-alpha (TNF-α). Finally, the infected fish’s cortisol levels and blood glucose were assessed. Results of BLAST sequence analysis of the 18S rRNA for the collected protozoans confirmed Myxobolus agolus, M. brachysporus, M. tilapiae, and Henneguya species. The molecular characterization of the immunological status of gills revealed marked upregulation of different inflammatory cytokines in the gills of infected fish. There was a significantly increased serum cortisol and glucose level in infected fish compared with control, non-infected ones. Severe histopathological alterations were observed in the infected fish gills, associated with increased expression of iNOS and TNF-α and related to myxosporean infection. The present study provides new insights into oxidative stress biomarkers in Nile tilapia infected with Myxosporeans and elucidates the gill’s immune status changes as a portal of entry for protozoa that contribute to tissue damage.
A panoramic driving perception fusion algorithm based on multi-task learning
Authors: Wu Weilin , Liu Chunquan , Zheng Haoran
Published: June 2024

With the rapid development of intelligent connected vehicles, there is an increasing demand for hardware facilities and onboard systems of driver assistance systems. Currently, most vehicles are constrained by the hardware resources of onboard systems, which mainly process single-task and single-sensor data. This poses a significant challenge in achieving complex panoramic driving perception technology. While the panoramic driving perception algorithm YOLOP has achieved outstanding performance in multi-task processing, it suffers from poor adaptability of feature map pooling operations and loss of details during downsampling. To address these issues, this paper proposes a panoramic driving perception fusion algorithm based on multi-task learning. The model training involves the introduction of different loss functions and a series of processing steps for lidar point cloud data. Subsequently, the perception information from lidar and vision sensors is fused to achieve synchronized processing of multi-task and multi-sensor data, thereby effectively improving the performance and reliability of the panoramic driving perception system. To evaluate the performance of the proposed algorithm in multi-task processing, the BDD100K dataset is used. The results demonstrate that, compared to the YOLOP model, the multi-task learning network performs better in lane detection, drivable area detection, and vehicle detection tasks. Specifically, the lane detection accuracy improves by 11.6%, the mean Intersection over Union (mIoU) for drivable area detection increases by 2.1%, and the mean Average Precision at 50% IoU (mAP50) for vehicle detection improves by 3.7%.

Published: June 2024

Objective

To evaluate the diagnostic performance of circulating tumor cells (CTCs) using tapered-slit membrane filter (TSF)-based chipsets for the differential diagnosis of adnexal tumors.

Methods

A total of 230 women with indeterminate adnexal tumors were prospectively enrolled. The sensitivity, specificity, and accuracy of the CTC-detecting chipsets were analyzed according to postoperative pathological results and compared with those of cancer antigen (CA)-125 and imaging tests.

Results

Eighty-one (40.3%) benign tumors, 31 (15.4%) borderline tumors, and 89 (44.3%) ovarian cancers were pathologically confirmed. The sensitivity, specificity, and accuracy of CTC-detecting chipsets (75.3%, 58.0%, and 67.1%) for differentiating ovarian cancer from benign tumors were similar to CA-125 (78.7%, 53.1%, and 66.5%), but lower than CT/MRI (94.2%, 77.9%, and 86.5%). “CTC or CA125” showed increased sensitivity (91.0%) and “CTC and CA-125” revealed increased specificity (77.8%), comparable to CT/MRI. CTC detection rates in stage I/II and stage III/IV ovarian cancers were 69.6% and 81.4%, respectively. The sensitivity to detect high-grade serous (HGS) cancer from benign tumors (84.6%) was higher than that to detect non-HGS cancers (68.0%).

Conclusion

Although the diagnostic performance of the TSF platform to differentiate between ovarian cancer and benign tumors did not yield significant results, the combination of CTC and CA-125 showed promising potential in the diagnostic accuracy of ovarian cancer.

Expanding landscapes: Articulating metamodernity in painting after Land art
Authors: Partridge Rebecca
Published: June 2024

This article considers some of the ways the cultural frameworks within which we create and dialogue are shifting in the twenty-first century, and how this might be articulated by emerging theories of ‘metamodernism’. It outlines some of the foundational issues to which metamodern theory speaks: hallmarks of postmodernism which have since become problematic within contemporary practice, exampled in approaches to painting landscape from the 1980s to 90s. The author considers the contradictions of postmodernism in relation to decolonization through aspects of critique that are both constructive and exclusionary. This leads to a broad overview of metamodern theory, outlining significant contributions to the field from a global perspective. It introduces some key ideas; simultaneity, depth, a ‘structure of feeling’ and a return to meta-narrative: characteristics of metamodernism which the article proposes as being first apparent in historical Land art. Through this lens the author articulates recent shifts in contemporary painting of/with and in landscape. Considering the resonances between Land art and painting in context of metamodern ideas, it is argued, contributes to cultivating a more embodied, non-essentialist, decolonized and outward looking approach to painting and landscape.
The politics of attention in the paintings of René Tavares
Authors: Nolasco Ana
Published: June 2024

René Tavares’s artistic production actively engages with political themes like migration and racism, simultaneously reflecting and inviting the deconstruction of the ‘alert attentional regime’. This term refers to our digital era's characteristic heightened state of alertness and fragmented attention, which scatters our focus across multiple streams of information. Rather than simply mirroring society’s fragmented attentional state, his work fosters more mindful and intentional engagement, encouraging viewers to transcend the transient attentiveness inherent in contemporary society. Central to his practice is the concept of rhythm, symbolizing the velocity of modern life and facilitating a shift to more sustained attention. This is achieved through patterns and colours that mimic swift information cycles, inherent to our times, captivating the viewer’s attention while setting the stage for a deeper, more mindful engagement with the artwork. Tavares intertwines elements like the ‘floating mark’, representing ephemeral meanings in our digital era; ‘polyfocality’, reflecting and addressing society’s fragmented attention through multiple focal points, and ‘pictorial syncretism’, which refers to the amalgamation of different painterly registers such as stains, graphic registers, splatters, layer overlay, word insertion and scrapings, blending visual traditions to highlight the fluid cultural boundaries in our globalized world. By doing so, it potentially opens up the possibility for a redistribution of the sensible, prompting critical thinking and an inherently political understanding of our place within a broader societal context.

The growth and homogenization of Democracy, which could be referred to as the globalization of Democracy, are fast increasing. Developing countries such as Nigeria practice a liberal democracy to promote the development and well-being of the people within a framework of justice and freedom. Election stands to be one post-colonial vital tool in a democratic project that encompasses several candidates representing political parties and cum the electorates, in which voting is very consequential in making decisions or selection of leaders/government to express the interest of a larger population of the people by holding a public office in a competitive struggle. Elections provide opportunities for the advancement of Democracy, encourage political liberalization, and foster political development participation. Since independence till date, several general elections have been held and characterized by one form of violence or the other, which have given rise to election rigging malpractices that result in unfree and unfair election outcomes; these have impeded the sole aim of democratization in Nigeria. In most cases, the ferocities have hampered the dream and aspirations of the people for good governance. The researcher evaluated the subject, and the work reviewed strands of literature to ascertain the causes and consequences of election violence in Nigeria’s contemporary democratic epoch; conclusions were drawn from the findings from the study and proffered measures on best to curb the issue.

Contemporary industry and science expectations towards technological solutions set the bar high. Current approaches to increasing the computing power of standard systems are reaching the limits of physics known to humankind. Fast, programmable systems with relatively low power consumption are a different concept for performing complex calculations. Highly parallel processing opens up a number of possibilities in the context of accelerating calculations. Application of SoC (System On Chip) with FPGA (Field-Programmable Gate Array) enables to delegate of a part of computations to the gates matrix, thereby expediting processing by using parallelization of hardware operations. This paper presents the general concept of using SoC FPGA systems to support CPU (Central Processing Unit) in many modern tasks. While some tasks might be really hard to implement on an FPGA in a reasonable time, the SoC FPGA platform allows for easy low-level interconnections, and with such virtualized access to the hardware computing resources, it is seen as making FPGAs, or hardware in general, more accessible to engineers accustomed to high-level solutions. The concept presented in the article takes into account the limited resources of cheaper educational platforms, which, however, still provide an interesting and alternative hybrid solution to the problem of parallelization and acceleration of data processing. This allows to overcome encountered limitations and maintain the flexibility known from high-level solutions and high performance achieved with low-level programming, without the need for a high financial background.

Published: June 2024

Purpose: This study aimed to investigate generational differences of teachers' perceptions on career prospects including promotion, turnover intention, and retirement age. Understanding these differences is essential for adapting educational practices to the evolving needs of the teaching society.
Methods: A survey was conducted with 2,064 elementary, middle, and high school teachers affiliated with the Seoul Metropolitan Office of Education. The responses regarding promotion, turnover intention, and retirement age were analyzed across generations X, M, and Z using frequency analysis and chi-square tests. Interviews on career prospects were also performed with thirteen teachers to gain in-depth insights into the generational differences and policy improvement.
Results: Findings revealed that while all generations found promotion unattractive, they shared different perspectives regarding the reasons. The younger generation showed a higher inclination towards turnover intention and a lower commitment to remaining in the profession until retirement age. The most common motivations for turnover intention were low wages and increased violations with respect to the rights of educational activities across generations. Generation X teachers expressed discomfort with the promotion system through the interviews while Generation M and Z teachers considered the cost-effectiveness aspect of promotion.
Conclusion: Generational disparities in teachers' perceptions of career prospects call for considerations in teacher policies. Subdividing promotion positions and expanding career paths will guarantee continued exercise of teachers’ expertise in the era of change.
