Published: November 2024

Steigende Kosten und der Klimawandel bedingen ein Umdenken im Umgang mit Ressourcen. Ressourcenschonende Entwicklungsansätze wie der Leichtbau sind branchenübergreifend gefragt. Das Wissen zur Leichtbauoptimierung ist in vielen Unternehmen jedoch nicht oder nur implizit vorhanden. Um die Vorteile des Leichtbaus zu heben, muss Leichtbaulösungswissen bereitgestellt werden. Infolgedessen wurde ein Ansatz zur musterbasierten Entwicklung von Leichtbauprodukten entwickelt.
Vom Halbzeug zum Feinschnittteil/From strip to fineblanking parts – How sheet metal surface affects sheared surface quality in fineblanking
Authors: Bergs Thomas , Herrig Tim , Voigts Herman
Published: November 2024

Das Massenfertigungsverfahren Feinschneiden eignet sich aufgrund hoher Maßhaltigkeit, geringem Kanteneinzug und hohem Glattschnittanteil für die Herstellung von Funktionsbauteilen wie beispielsweise Verzahnungen. Die Schnittflächenanforderungen müssen auch in Grenzbereichen durch neue Werkstoffe oder filigrane Schnittkonturen erfüllt werden. Vor diesem Hintergrund wurde untersucht, wie die Bildung von Kanteneinzug und Einrissen durch die gewalzte Blechoberfläche beeinflusst wird.
Werkzeugseitige Chargenschwankungen beim Schleifen/Tool-side batch fluctuations during grinding – How batch fluctuations affect the state and result variables during grinding

Published: November 2024

Da bisherige Modelle werkzeugseitige Chargenschwankungen nicht berücksichtigen, ist die Übertragbarkeit der Modelle in die Praxis nur eingeschränkt möglich. Auch deswegen werden immer noch 8–16 % der Fertigungszeit für die Prozessanpassung aufgewendet. Um die Auswirkung des Einsatzes chargenverschiedener Werkzeuge zu quantifizieren, wurden Schleifuntersuchungen durchgeführt und der Einfluss von Chargenschwankungen auf die Zustands- und Ergebnisgrößen ermittelt und erklärt.
IMPLEMENTING ETHNIC TOURISM AS A TOOL CONTRIBUTING TO THE DESTINATION COMMUNITY WELL-BEING IN THE CENTRAL HIGHLANDS, VIETNAM
Authors: Nguyen Thi Thanh Kieu
Published: November 2024

Despite being well-recognized as a means of poverty alleviation in poor remote areas, ethnic tourism should not be solely pursued for economic benefits as an end goal for the host community. To achieve sustainability and destination community well-being, it is argued that ethnic tourism can become a tool to improve various types of community capital rather than only economic capital. The main goal of this study is to identify strategies to improve community capital in an ethnic tourism destination. By conducting a community workshop with 34 local tourism stakeholders in the Central Highlands, the study found that the top priority was placed on human capital and political capital. First, local wisdom and genuine characteristics of naivete, honesty, friendliness, and hospitality need to be promoted to attract visitors, while local residents need to be educated and trained to build capacity for improving tourism services and to actively engage in the tourism decision-making process. Second, improvements in political capital were strongly suggested to tackle common barriers to community empowerment and collaboration, tourism organizational structure, local policies, standards, and assessment procedures. This study reaffirms the interrelationship and synergy among types of community capital and proves the value of the destination community well-being approach to ethnic tourism planning and governance. Future research implications are also presented.
Potential of Honey Bee Propolis and Venom as Eco-friendly Control Agents in Galleria mellonella L.
Authors: Taha Amro , Younis Mohamed , . Al-Ghanam Heba , Abou El-Atta Doaa
Published: November 2024

The study was conducted to determine the toxicity approach of four honey bee propolis and venom concentrations, 500, 1,000, 2,000 and 3,000 ppm, regarding the biological aspects of the wax moth larvae Galleria mellonella L. Using 2,000 and 3,000 ppm propolis concentrations gave a 100% reduction percentage on wax moth larvae after spraying the treatment for 72 and 48 hours consistently. Applying 3,000 ppm of bee venom resulted in a 100% mortality percentage for the three test times of 24, 48 and 72 hours. The lowest period of larval development was observed when propolis was used at a concentration of 3,000 ppm, with an average of 7.66±0.33 days. At the 3,000 and 2,000 ppm concentrations of propolis, the pupal stage was unable to develop for adults of the insect, as all the individuals died. For bee venom, at concentrations of 3,000 and 2,000 ppm, none of the larvae have succeeded in the development of pupa or adult insects. Bee venom was the most effective substance against wax moth larvae, followed by propolis; LC50 values were 272.62 and 3,166.42 ppm, respectively. These results clarified the need for more research to affirm their effect in the field and on honey bees.

Subliminal priming modulates motor sequence learning
Authors: Simpson Michael William , Wu Jing , Ye Zheng
Published: November 2024

Sequential behaviour is underpinned by the selection and inhibition of movement at appropriate points in space and time. Sequences embedded among movement patterns must be learnt, yet the contribution of response selection and inhibition to the acquisition of motor sequences remains poorly understood. We addressed this issue by overlaying the serial reaction time task (SRTT) with subliminal masked primes that differentially weighed response tendencies. In Experiment 1, twenty-four healthy young adults, and in Experiment 2, thirty-six participants, performed the SRTT with congruent (same position), incongruent (different position), or neutral (no prime) subliminal masked primes. Each condition featured an embedded eight-digit (Experiment 1) or ten-digit (Experiment 2) second-order sequence, with conditions presented in counterbalanced order during a single session. Sequence specific learning was observed under neutral and congruent prime conditions. Independent of sequence awareness, congruent primes reduced initial response latency and led to greater sequence specific learning compared with neutral primes. However, incongruent primes appeared to attenuate learning (Experiment 1). These results demonstrate that prime congruency modulates sequence specific learning below the threshold of conscious awareness. Congruent primes may elevate the salience of stimulus–response compounds and accentuate learning, but at the cost of increased awareness. Incongruent primes, and the induction of response conflict, attenuate sequence specific learning (Experiment 1) and may prevent the formation of cross-temporal contingencies necessary for implicit motor sequence learning.

Authors: Aloysius Morris, T. , Eleni Andreou , Felekkis Kyriacos , Petrou C. , Evans Egwim Chidi
Published: November 2024

Glucose uptake and growth kinetics with extract fractions of Dioscorea dumetorum was studied employing standard procedures. Pure yeast cell line culture was used to estimate the capability of yeast cell to grow and take up glucose from the system facilitated by extract fractions from food plants. Result shows that kinetics of yeast cell growth with extract fractions at higher rates met up with the healing faster. Some of these extract fractions were very active at very low concentrations compared to standard drug; these can be drug candidates for formulating type 2 diabetes drug that may compete favourable with standard medications which are burdened with side effects and diverse levels of difficulties. The extract fractions being of food plant origin has no likely toxicity and are a natural antioxidant. Kinetic modeling of the extract fractions with yeast cells have suggest a ‘Time-Bound Insulin Releasing System’ (TBIRS) where uptake of glucose was possible at specific given time similar to a intial insulin release kinetics which may lead to prospects for the design of type 2 diabetes medications to support an all-embracing blood glucose control, which is really essential by diabetics in order to reduce the difficulty of drug systems as there is a high probability of the extract fractions effectiveness in the future as drug candidate for type 2 diabetes.

Capgras Syndrome (CS), also known as the illusion of doubles, is a subtype of Delusional Misidentification Syndromes (DMS), often observed in psychotic manifestations of Alzheimer’s disease (AD). The prevalence of DMS in AD psychosis is estimated to be approximately 30%, with 5% to 16% of DMS cases presenting with CS. The pathophysiology of CS remains unclear mainly; however, one prevailing hypothesis suggests that it may result from disrupted connectivity between brain regions responsible for facial recognition and those involved in emotional processing. Currently, there is no standardized treatment protocol for CS. However, some improvement has been noted with standard AD treatment regimens and validation therapy, which involves acknowledging and verbalizing the patient’s emotions. This paper aims to provide a detailed description of a clinical case and an overview of the pathophysiology of CS. We present the case of an 83-year-old female patient with a medical history significant for major depressive disorder, major neurocognitive disorder, and several comorbid conditions who was referred to our clinic with complaints of memory and attention impairment, temporal disorientation, behavioral disturbances, and delusions. The patient’s medical history revealed a delusional conviction that her daughter had been replaced by an imposter, a belief that persisted during in-person interactions but was absent during telephone conversations. A brain scan computer tomography (CT) revealed cerebral and cerebellar atrophy, and the patient’s Mini-Mental State Examination (MMSE) score was 19/30.

Published: November 2024

This paper examines how zakat management’s accountability and transparency  affect the muzzaki’s willingness to pay their zakat to a zakat management institution. The study was motivated by the crucial role of zakat in Muslim countries as a potential resource for improving their socio-economy. However, accountability and transparency of zakat institutions have failed of expectations. Muzzaki tend to give their zakat through mosques or non-profit organisations where less accountability and transparency. Prosocial behaviour theory which emphasises voluntary action to help others is selected. Meanwhile, mixed methods focusing on qualitative to facilitate quantitative methods are selected through Interview and distributing questionnaires to Muslims in the Bandung-Indonesia. 300 questionnaires were analysed using the PLS-SEM tools. This study reveals being transparent from the zakat management institution is control but when it comes to muzzaki behaviour, intention and choice to pay zakat as a voluntary expression of solidarity, it is made through official channels.

Published: November 2024

Intensive shrimp farms sometimes experience cases of death of vaname shrimp (Litopenaeus vannamei) due to infection with various pathogens and one of these diseases is EHP (Enterocytozoon Hepatopenaei). This disease mostly attacks vaname shrimp in the post-lava phase, EHP can take up nutrients in the digestive tract so that it can inhibit growth, non-uniform size variations and be deadly. EHP can also become a primary infection and open the way for other disease. This research used an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments with 5 replications. The results showed that treatment A gave the best results for the prevalence of EHP disease in white shrimp (Litopenaeus vannamei) from PL8–DOC40 at 7%. Water quality data obtained from water temperature ranged from 27.1 to 29.9 0C, acidity ranged from 7.1 to 8.6 and dissolved oxygen ranged from 5.14 to 5.87 ppm.

Authors: Kirana Adelia Nindya , Rahaditya R.
Published: November 2024

The Law on the Juvenile Justice System in Indonesia has been designed to prioritize the protection of children through the implementation of restorative and diversion approaches. The primary aim of this approach is to enable children involved in legal issues to be reintegrated into society and to have a better chance for their future. However, data shows that many juvenile criminal cases end with imprisonment, which contradicts the goals of this Law. Therefore, it is necessary to optimize the juvenile justice system to achieve fair sentencing. This research employs a normative legal method with a descriptive-analytical approach and utilizes a statutory approach to analyze the Law and related regulations. Data was collected through literature study, including both primary and secondary data. The analysis was conducted qualitatively to provide a comprehensive understanding. Diversion, as a restorative justice effort, serves to protect children and resolve cases outside the formal judicial process, while the author emphasizes the need for improvements in the rehabilitation of juvenile offenders to prevent reoffending.
Legal Certainty of Binding Power of Marriage Agreements Not Registered of Notary
Authors: Wulandari Janita , Djaja Benny , Sudirman Maman
Published: November 2024

This study discusses the legal certainty related to the binding force of marriage agreements that are not registered by a notary, by referring to the Constitutional Court Decision Number 69/PUU-XIII/2015. In this decision, notaries are given the authority to validate marriage agreements. However, agreements that are only validated by a notary without being registered with the Office of Religious Affairs or the Population and Civil Registration Service do not fulfill the principle of publicity, which is important to ensure that the document can be accessed by third parties who may be affected. Without registration, the agreement does not have binding legal force for third parties, thus potentially causing legal uncertainty and disputes in the future. The principle of publicity aims to provide protection for third parties by ensuring access to the rights and obligations stipulated in the agreement. Registration of marriage agreements at the Population and Civil Registration Service provides stronger legal certainty, maintains transparency, and protects the rights of all parties involved in accordance with applicable legal provisions.

Authors: Rohadi Rohadi , Sejati Hono , Susilowati Tri
Published: November 2024

The legal vacuum in the regulation of standard contracts in the banking industry in Indonesia has become an increasingly pressing issue, given the rising dependence of the public on financial services. This study aims to explore various aspects related to the legal vacuum and the dominance of standard contracts, which often disadvantage consumers. By analyzing the provisions in the Consumer Protection Law and existing banking practices, this research identifies the negative consequences of regulatory ambiguities that facilitate abuse by banks. The study also discusses the efforts that need to be made by the government and the Financial Services Authority (OJK) to create a stronger and more transparent legal framework. The results indicate that tighter regulations and effective supervision can strengthen consumer bargaining power and reduce the risk of losses due to unfair terms in standard contracts. Thus, this research is expected to contribute to the development of more equitable and sustainable policies in the banking sector.
The Urgency of Imprisonment as a Substitute for Restitution in Upholding Justice for Rape Victims
Authors: Khoirudin Khoirudin , Sejati Hono , Tohari Mohamad
Published: November 2024

The legal vacuum regarding imprisonment as a substitute for restitution in Indonesia is a serious issue that directly affects the enforcement of justice for rape victims. In many cases, perpetrators of crimes are often unable to pay the restitution that should be afforded to victims, thereby denying victims their rights to receive compensation for the harm suffered. This legal uncertainty not only hampers the psychological and emotional recovery of victims but also creates a perception that the justice system is unable to deliver the justice it should. This article examines the urgency of implementing imprisonment as a substitute sanction for perpetrators who are unable to pay restitution, as well as exploring the weaknesses in existing legislation and efforts that can be made to address this legal vacuum. Through appropriate legal reforms, it is hoped that the rights of victims can be effectively protected, and the criminal justice system can impose appropriate sanctions on perpetrators, thereby enhancing public trust in justice.
Kesesuaian Lahan Sawah Dilindungi (LSD) Terhadap Kebijakan Rencana Tata Ruang di Kabupaten Gianyar

Published: November 2024

Pertumbuhan penduduk berimplikasi pada kebutuhan pangan. Pertumbuhan penduduk seharusnya diiringi dengan pertumbuhan ketersediaan pangan. Namun ketersediaan lahan untuk memenuhi kebutuhan manusia bersifat tetap, hal ini menyebabkan ketersediaan pangan akan terancam. Pemerintah Republik Indonesia kemudian membuat kebijakan Lahan Sawah Dilindungi (LSD) untuk mengamankan ketahanan pangan beserta penetapan delineasi LSD. LSD harus tersinkron dengan kebijakan tata ruang, dikarenakan urgensinya kejelasan aturan dalam rangka pemenuhan swasembada pangan nasional. Penelitian ini bertujuan mengetahui kesesuaian LSD terhadap kebijakan tata ruang di Kabupaten Gianyar. Penelitian ini menggunakan pendekatan keruangan pada tema pola keruangan. Pengumpulan data menggunakan data sekunder kemudian dianalisis dengan pendekatan keruangan menggunakan Sistem Informasi Geografis (SIG). Untuk mengetahui pola sebaran kesesuaian menggunakan metode overlay. Penelitian ini menemukan bahwa 7.315,96 Ha (70%) delineasi LSD diatur sesuai sebagai tanaman pangan dalam rencana tata ruang. 7.135,580 Ha (68%) LSD merupakan Kawasan Pertanian Pangan Berkelanjutan (KPPB). Tidak terakomodirnya delineasi LSD sebagai kawasan tanaman pangan pada kebijakan rencana tata ruang akan berdampak pada perizinan tata ruang, dikarenakan adanya ketidakpastian peruntukan ruang. Kemudian belum sesuainya delineasi LSD sebagai KPPB akan berdampak pada munculnya peluang perubahan peruntukan lahan. Perlu dilakukan sinkronisasi antara LSD terhadap KPPB dan Rencana Tata Ruang. Sinkronisasi dilakukan pada tahapan perancangan materi teknis sampai pada legalitas menjadi peraturan.

Published: November 2024

Con el propósito de evaluar el efecto combinado de la materia orgánica y la fertilización fosfórica sobre el desarrollo de las plantas de café en la etapa de almácigo, se realizó un experimento en la Subestación Experimental Santander, ubicada en el municipio de Floridablanca y propiedad de la Federación Nacional de Cafeteros de Colombia. Como fuentes de materia orgánica (MO) se emplearon gallinaza, pollinaza y lombrinaza de pulpa de café (abonos comunes en el departamento), las cuales se mezclaron con suelo en las siguientes proporciones: 25-75, 50:50 y 75-25 (MO:Suelo). Como fuentes de fósforo se emplearon Fosfato diamónico-DAP (18% N y 46% P2O5) y Superfosfato triple-SFT (46% P2O5 y 19% CaO); fertilizantes similares en lo contenidos de fósforo, pero contrastantes en su composición y reacción química (acidificación). Se obtuvieron entre otras las siguientes conclusiones: 1. El compost de gallinaza y pollinaza puede utilizarse como fuente de abono orgánico para el crecimiento y el desarrollo de plantas de café en etapa de almácigo; 2. Con la mezcla del 20% de gallinaza más 80% de suelo ó 25% de pollinaza o lombrinaza por 75% de suelo, se obtienen los mayores incrementos en el peso seco de las plantas de café en etapa de almácigo; 3. Cuando se emplean suelos con altos niveles de fósforo (más de 14 mg/kg) para el establecimiento de plantas de café en etapa de almácigo, la aplicación de este nutrimento puede ser una práctica innecesaria; 4. La aplicación de DAP en dosis superiores a 4 gramos por planta en suelos de pH ácido, puede causar efectos negativos en el crecimiento de las raíces, por el efecto residual ácido de este fertilizante. En este caso se puede emplear como fuente el fertilizante Superfosfato triple.

Authors: Mushumba Dr. Martin , C. Chinsembu Prof. Kazhila , Mwanza Prof. Gideon
Published: November 2024

This study aims to assess the impact of the Higher Education Authority of Zambia (HEA) on the quality of teaching and learning in higher education institutions (HEIs) in Zambia providing a thorough analysis of the HEA’s influence on Zambian higher education, offering insights into both its successes and areas needing improvement. The HEA was established with the aim of improving the quality of teaching and learning in HEIs in Zambia. In Zambia, the HEA plays a crucial role in regulating and enhancing educational standards across HEIs. The role of HEA is crucial in the quality of higher education in Zambia including in teaching and learning (Masaiti & Simuyaba, 2018). The quality of teaching and learning in higher education is essential for national development and individual success (Constantinou & Wijnen-Meijer, 2022; Zimba, 2021). This article examines the HEA’s impact on teaching and learning quality, exploring its regulatory framework, implementation strategies, and effectiveness. By analysing policy documents, reviewing literature, presenting case studies, and through focus group discussions, this study provides a comprehensive assessment of the HEA’s role in shaping the quality of teaching and learning across the country's higher education institutions.

Background: Recurrent spontaneous abortion defined as three or more consecutive pregnancy loss before 24 weeks is a challenge for gynecologists because of the complex and variable etiologies behind. Exploring characteristics of patients with this condition may help researchers and clinicians. Therefore, the aim of the present work was to outline the demographic and patient history wise factors related to RSA and to analyze the association of those factors with occurrence of RSA. Methods: Case control study included cases collected from Benghazi medical center from records of deliveries January 2020 to December 2020. Statistical analysis was executed using SPSS 23.0. Results: A total of 250 cases were investigated. Among those 30 cases met the definition of RSA. The rate of explained abortion among subset with spontaneous abortion was only 10.0%. The rate of advanced maternal age among the study population was 29.2%. The rate of RSA was higher among mothers with advanced maternal age (15.1% for 10.7%). This difference was statistically insignificant (P=0.338). The history of abortion among the study population showed a rate of first trimester abortion was 36.8% and second trimester abortion as 4.8%. RSA rate was much higher among mothers with history of 1st trimester abortion (20.7% for 7.0%) with statistically significant association (P<0.001) and OR of 3.5 (95% CI; 1.6–7.7). In multivariate analysis the history of 1st trimester abortion was an independent predictor for RSA. Also, in multivariate analysis, secondary infertility was independent negative predictor for RSA, (P=0.034 and OR=0.18; 95% CI: 0.04–0.88). The rates of bad obstetric history, HDP, GDM, any medical condition and history of low vitamin D3 were 15.2%, 17.2%, 8.8%, 16.8% and 19.2%; respectively among the study population. Mothers with bad obstetric history have a higher rate of RSA (18.4% for 10.8%), but the difference is not statistically significant (P=0.183) No significant association between HDP, GDM, history for medical conditions or history of low serum vitamin D with RSA (P=0.934, 0.735, 0.308 and 0.109 respectively). Conclusion: Recurrent spontaneous abortion is under-investigated and seems to be more likely with first trimester abortion and it is may be associated with several factors like infertility and maternal age. Anyhow, those associations need to be verified. Considering early investigations for couples with spontaneous abortion within the first trimester and further well designed prospective study are recommended.

Published: November 2024

The quality and completeness of the reference database have a direct impact on the accuracy of forage plant identification, thereby influencing the level of conservation and management of wildlife resources. In our research, target amplification was subjected to first-generation sequencing to assemble a local reference database using chloroplast trnL metabarcoding. We found that the primers c-h outperformed g-h as a universal DNA metabarcoding and 162 valid choloroplast trnL sequences were submitted (GenBank ID: PP081756 - PP081917), which exhibited an obvious preference for A and T nucleotides (60.49%). The haplotype diversity (Hd), nucleotide diversity (Pi) and average number of nucleotide differences (K) of these trnL sequences were 0.978, 0.0484 and 4.743, respectively. To assess the availability of the local database in identifying the diet of South China sika deer (Cervus nippon kopschi), high-throughput metabarcoding sequencing and BLAST analysis were performed. Ultimately, 25 forage plant species were identified, belonging to 19 families and 25 genera. Shrubs and herbaceous plants, such as Potentilla freyniana, Persicaria perfoliata, Rosa laevigata and Ardisia japonica etc, dominated the forage plants. This study established a local trnL reference database that holds immense value for the forage plant identification and nutritional evaluation for sika deer and other sympatric herbivores, as well as the conservation and management of biodiversity.
Desert diversification: revision of Agroecotettix Bruner, 1908 (Orthoptera, Acrididae, Melanoplinae) with descriptions of sixteen new species from the United States and Mexico
Authors: Hill JoVonn G.
Published: November 2024

In this study, a morphological revision was conducted of Agroecotettix Bruner, a group of grasshoppers inhabiting open xeric desert scrub, shrublands, and plains, spanning central Texas to central Mexico. The genus was originally described by Bruner in 1908, with two taxa added by Hebard in 1922. Agroecotettix has remained unrevised despite numerous collections. This exploration, spurred by a novel discovery of significant male genitalia variation in Agroecotettix aristus aristus, suggests undescribed species. Through morphological specimen comparisons, sixteen new species are described from biologically rich regions of the South Texas Plains, Chihuahuan Desert, and Sierra Madre Oriental. The new taxa described here are A. silverheelsisp. nov., A. xiphophorussp. nov., A. glochinossp. nov., A. texmexsp. nov., A. cumbressp. nov., A. burtonisp. nov., A. mooreisp. nov., A. chiantiensissp. nov., A. dornisp. nov., A. chisosensissp. nov., A. turnerisp. nov., A. quitmanensissp. nov., A. vaquerosp. nov., A. forcipatussp. nov., A. idicsp. nov., and A. kahloaesp. nov. This discovery sheds light on desert biodiversity and hints at a Pleistocene radiation akin to other melanoplines, urging further exploration to enrich our understanding of this fascinating lineage and unravel the biogeographic history within these arid landscapes.
Education in England: an ailing system, historical amnesia and hope for the future
Authors: Moss Peter
Published: November 2024

This article reprints the introduction (minus the final paragraph) to FORUM’s latest ebook: ‘Renewing public education: proposals for an inclusive, democratic and joyful system’. Peter Moss diagnoses the malaise which has long afflicted English public education, tracing
the source of the distemper to the effects of the Global Education Reform Movement and offering hope of a cure. By recalling to mind and practice the exiled ‘progressive’ tradition in education and the alternative perspectives and approaches it offers, he shows how we can begin
to write a better, more democratic, story for public education in England.
Reimagining English schooling: unlocking potential through community partnerships
Authors: Bishop Jo , Martin Doug
Published: November 2024

The 1988 Education Reform Act (ERA) changed the direction of statutory education in England by introducing a culture of competition between schools. A market in education was created that placed school against school in neighbouring communities with the aim of the ‘fittest’
ones surviving while the weaker ones failed and closed. By the end of the 20th century, the epidemic of neoliberalism served to shift all of our public services through creation of these quasi-markets towards competition. While schools led the way, other essential services we rely on such
as water, energy and transport fell foul of marketisation. We all became consumers ostensibly to improve efficiency and the quality of the final ‘product’. Over recent years this approach has become discredited as transport and other services return to democratic control, whereas
schools remain locked in a straitjacket of competition. During the Covid-19 pandemic of 2020, schools become much more than a competitive education service, they rapidly transformed into an essential mainstay of our communities, indeed of our society. This article will utilise the learning
from research across three diverse secondary schools that provided accounts of their experiences prior, through and post pandemic. We use an understanding of their experiences to help reshape English schooling and through this argue for a repositioning of school as an essential community resource

The elephant in the exam room
Authors: Bray David
Published: November 2024

This short article notes the disruption to public examinations caused by the Covid-19 pandemic and resultant lockdowns. This provides a context to examine the way norm-referencing controls the distribution of grades in England’s test and examination system. This is viewed as ‘the
elephant in the exam room’, something accepted, normalised and hidden in plain sight. A proposal is made for a system of criterion referencing, where the hard work of pupils and teachers can be recognised, or where vocational examinations can be rewarded without fears over declining
standards. Finland is noted as a school system which is highly regarded within international comparisons.
Cultivating the sociological imagination: fostering inclusive and democratic classrooms
Authors: Jones Andrew B.
Published: November 2024

This paper advocates for the integration of the ‘sociological imagination’, as proposed by the sociologist C. Wright Mills, into pedagogical practices to foster inclusive and democratic classrooms. Departing from narrow evidence-based approaches, it explores how the sociological
imagination connects personal experiences with broader societal structures, enhancing critical thinking and social awareness among students. Practical strategies for implementation across diverse subjects are discussed, emphasising its potential to empower school-age students as agents of
social change amidst contemporary challenges.
Isolated Idiopathic Inferior Rectus Myositis: Taming a Rare Disease at a Rare Site
Authors: Shetty Shashikant , Devaraj Athira , Kim Usha , Vijayalakshmi Permulasamy , Padurangan Sneha
Published: November 2024

The authors report a case of a 66-year-old man with sudden-onset diplopia and redness in the left eye. The examination revealed left hypotropia with exotropia and limited elevation. Contrast-enhanced computed tomography and histopathology suggested inferior rectus myositis with fibrosis. The patient was treated with steroid pulse therapy, followed by slow tapering. Later, the patient underwent surgical strabismus correction. He remained diplopia-free with an excellent cosmetic outcome and minimal elevation deficit 12 months postoperatively.

Levator Resection and Tarsorrhaphy as a Treatment for Bilateral Asymmetric Nystagmus With Oscillopsia
Authors: Moreno-Gutiérrez Juan Ángel , Flores-Márquez Ana , Alijo-Serrano Encarnación , García-Marcet Susana , Ibáñez-García Ainsa
Published: November 2024

The authors describe surgical occlusion with levator resection and partial tarsorrhaphy as a treatment for nystagmus with oscillopsia refractory to medical or surgical therapies. This was a case of Bardet-Biedl syndrome with high myopia and acquired sensory pendular nystagmus in both eyes, where a well-known technique was applied to a novel indication. Permanent occlusion of the left eye led to significant improvement in visual acuity and reduced oscillopsia, enhancing the psychological and social functioning. This case highlights the complexity of treating refractory nystagmus with oscillopsia and proposes surgical occlusion as a viable option for improving patient outcomes in severe cases.

Traumatic Unilateral Internuclear Ophthalmoplegia in a 5-Year-Old Child
Authors: Kates Malcolm M. , Sahawneh Morghan , Tauscher Robert
Published: November 2024

The authors present the case of a 5-year-old boy who developed a unilateral internuclear ophthalmoplegia (INO) following mild head trauma with supporting magnetic resonance imaging (MRI) findings of damage to the medial longitudinal fasciculus. At 2 months of follow-up, the patient had resolution of diplopia and only minimal residual nystagmus. Although rare in the children, INO can develop following head trauma. Management should include work-up to exclude etiologies beyond trauma (specifically with MRI, which is superior to computed tomography imaging in evaluating INO) followed by observation and, if needed, comanagement of any amblyogenic potential from ocular misalignment.

Compact modified rectangular split ring resonator for tri-band satellite applications
Authors: Fadhel Abderraouf , Berhab Souad , Aloulou Rahma , Mnif Hassene , Belhedri Abdennour
Published: November 2024

This paper contributes to the design of a modified rectangular-shaped metamaterial with a tri-band coverage for reflection and transmission coefficients. Two symmetrical rectangular split ring resonators (SRR) were carefully engineered and then connected by their edges along the axis (Ox) with a substantial C-shaped structure, experiencing the peak surface current value near the magnetic resonances, causing the proposed unit cell to resonate at 5.73 GHz, 8.67 GHz, and 13.78 GHz, where it exhibited negative effective permittivity (ENG), permittivity and permeability (DNG), and permeability (MNG), respectively. A total of 6 × 6 mm2 modified SRR was printed on Rogers RO3006 to achieve a better effective medium ratio (EMR) in the C band (4.55-6.27 GHz), X band (7.81-9.45 GHz), and Ku band (13.15-14.37 GHz), respectively. A comprehensive parametric analysis was performed to illustrate the effect of crucial parameter h on the scattering parameters (S11, S21) of the metamaterial resonant structure (MRSRR) in the specified frequency ranges. Structure underwent additional testing with 1 × 2, 2 × 1, 2 × 2, and 4 × 4 arrays, yielding results that demonstrated sufficient concordance for consideration in the C band [4-8 GHz], X band [8-12 GHz], and Ku band [12-18 GHz] satellite applications. Computer Simulation Technology (CST) Microwave Studio was utilized to reach the scattering parameters and their effective medium characteristics, specifically permittivity and permeability, via the Nicolson–Ross–Weir (NRW) approach, executed through MATLAB code. The surface current was examined, and the corresponding circuit model was confirmed utilizing the Advanced Design System (ADS) software, with results compared against the CST simulation outcomes.
Estimation techniques utilizing dual auxiliary variables in stratified two-phase sampling
Authors: Albalawi Olayan
Published: November 2024

In this research paper, an improved set of estimators for finding the finite population variance of a study variable under a stratified two-phase sampling design is introduced. These estimators rely on information about extreme values and the ranks of an auxiliary variable. We examined the properties of these estimators using first-order approximation, focusing on biases and mean squared errors (MSEs). Additionally, we conducted an extensive simulation study to evaluate their performance and validate our theoretical insights. Furthermore, in the application section, we employed some datasets to further assess the performances of our estimators as compared to other existing estimators. The results demonstrated that $ S^2_{Q_2} $ was the best-performing estimator, and significantly outperforms existing estimators, achieving a percent relative efficiency $ (PRE) $ in the exponential distribution as high as 385.467. The percent relative efficiency values were continuously higher than 100 in a variety of situations, with values as high as 353.129 in other distributions like the uniform and gamma. The suggested estimators are superior to the conventional estimators, as demonstrated by empirical assessments using datasets, where percent relative efficiency improvements ranged from 115.026 to 139.897. These results highlight the robustness and applicability of the proposed class of estimators in real-world sampling.

Daljšanje osnove z j je ena izmed oblikoslovnih posebnosti slovenskega jezika, ki se pojavlja pri nekaterih skupinah samostalnikov prve moške sklanjatve. Čeprav gre izhodiščno za oblikoslovno vprašanje, je v prispevku predstavljena obravnava daljšanja z j v pravopisnih priročnikih, ki so namenjeni širšemu krogu uporabnikov. Predstavljene so posamezne skupine samostalnikov moškega spola, s poudarkom na tujih lastnih imenih, pri katerih so (gledano kronološko) v priročnikih rešitve neusklajene ali pa jih je bodisi zaradi neskladne govorne in pisne podobe bodisi izkazane variantnosti mogoče uvrstiti med težavnejše primere.
Linguistic Diversity in Croatia: Historical and Contemporary Perspectives on Language Contact (and Conflict) in the Zadar and Varaždin Regions
Authors: Škifić Sanja , Pavić Pintarić Anita
Published: November 2024

This article deals with historical and contemporary language contact between Croatian on the one hand and Italian and German on the other in the Zadar and Varaždin regions. It focuses on language contact identifiable in the analysis of linguistic items related to space and occurrences in space. Because language contact frequently results in language conflict, it also considers the possibility of correlating the two phenomena based on a corpus analysis and from the perspective of three areas of interest: language, individual language user(s), and society. The findings suggest that there is a difference between coastal and continental language contact and conflict in manners of naming places, but also that the contemporary language conflict between the languages analyzed is not as prominent as it was in the past.
