DINÁMICA DEL CARBONO Y NITRÓGENO DEL SUELO EN ECOSISTEMAS DE LA COSTA TROPICAL SECA, EN LA MANCHA (CICOLMA), VERACRUZ, MÉXICO
Authors: Suarez M. Gabriela , Campos C. Adolfo , Cruz H. Lourdes
Published: December 2023

This study was carried out at the La Mancha Coastal Research Center (CICOLMA) in tropical semi-deciduous forest, secondary forest and two locations in coastal dune scrub (crest and slack). The aim was to study the carbon and organic nitrogen dynamics of the soil to quantify organic matter mineralization and nitrogen supply. In the laboratory, soil samples were incubated at 25 Â°C for 97 days and over this time 10 samples were analyzed to monitor the soilâ€™s carbon (CO2-C) and nitrogen ( , ) dynamics. The results reveal that mean cumulative organic carbon content was: dune slack (2.70 mg g-1) > secondary forest (2.0 mg g-1) > semi-deciduous forest (1.9 mg g-1) > dune crest (1.2 mg g-1). A comparison of the means using Tukeyâ€™s test (Î± = 0.05) detected differences only between the dune slack and the crest. Mean cumulative inorganic nitrogen content was: secondary forest (1284 mg kg-1) > dune slack (1140 mg kg-1) > semi-deciduous forest (1021 mg kg-1) > dune crest (302 mg kg-1), with significant differences only between the dune crest and the other treatments. In general, organic matter mineralization was higher in the dune slack and nitrogen supply was higher in the secondary forest. We conclude that organic matter mineralization and nitrogen supply are depending on the type of ecosystem and soil properties.

Currently, cattle systems have the challenge of improving their efficiency in order to satisfy the growing demand of livestock products while at the same time reducing their emissions. In order to estimate the main environmental impacts of bovine milk production and identify mitigation alternatives, a life cycle analysis (LCA) was conducted to compare an intensive silvopastoral systems (ISS) and a conventional system (CS) in Colombia. The structure of ISO 14044 was followed, with four functional units (FU); the estimated environmental impacts were: land use (LU), use of non-renewable energy (UNRE) and emissions of greenhouse gases (GHG). For all FU, the ISS had lower emissions of GHGs than the conventional system. To produce one kg of fat- and protein-corrected milk (FPCM) the ISS emitted 1 less GHG than the CS (2.05 vs. 2.34 kg CO2-eq). Regarding the use of non-renewable energy, the ISS required only 63% of the energy used in the CS to produce one kg FPCM (3.64 vs. 5.81 kg Mj-1) whilst for land use, the CS was more efficient in all UF compared to the ISS. We conclude that in ISS there are lower environmental impacts per unit of product, emitting less GHG and having lower UNRE.

Published: December 2023

The objectives of this study were to estimate the diversity of maize farmed by maize growers (“milperos”) of the Yucatan Peninsula, to review the state of maize conservation from 1948 to 2010, and to try out participative methods to best conservation and improvement of maize. Data of samples collected in 1948, 1974 and 1977 were analyzed; ethnobotanical explorations were carried out in 1999 and 2010; three cycles of visual stratified masal selection with four Creole maize were also practiced; and exhibition seeds in 44 localities were registered. The 1999 and 2010 explorations included 153 donors from 56 localities and 177 donors from 68 localities, respectively. Two-hundredth and thirty-six and 163 seed samples were collected from local populations of maize in the first and second exploration. The samples collected in 1999 and 2010 corresponded to the Tuxpeño, Dzit-Bacal, Nal-Tel landraces and crosses of them. In 1999 and 2010, it was found that 66.7% and 71.0% of the “milperos” interviewed, conserved and selected seeds from their maize populations for 6 or more years. The conservation of local maize increased 15.5%. However, the conservation of Dzit-Bacal maize decreased 14.2% in 10 years; therefore, its informal supply was strengthen in regional exhibitions of seeds and participative improvement of populations of that maize landrace was carried out, to reinforce its in-situ conservation and diversity.

Conservation of soil moisture through tillage practices is an important management objective for crop production in semi-arid areas. A study to evaluate the effects of tillage practices on maize and bean yields was conducted in Mwala Sub County, Eastern Kenya, in the long (LR) and short rains (SR) of 2012/13. The tillage treatments were: Disc Ploughing (DP), Disc Ploughing and Harrowing (DPH), Ox-ploughing (OX), Subsoiling – Ripping (SSR), Hand hoeing with Tied Ridges (HTR) and Hand hoeing (H) only. There were three cropping systems of Sole Maize (SM), Sole Bean (SB) and Maize - Bean intercrop (M + B), which were investigated in a Split-Plot Design field experiment with four replications. Data on maize and bean yield and yield components were monitored throughout the four cropping seasons. Maize plant height, leaf area and leaf area index, maize and beans grain and biomass yields were significantly affected by tillage (P < 0.05). No significant effect of cropping systems on the maize height was observed. Higher maize grain yields (P < 0.05) were obtained in the sole maize plots in LR 2012 (5.01 Mg ha-1), SR 2012 (4.19 Mg ha-1) and in the SR 2013 season (2.82 Mg ha-1). A three - season bean grain yield average by tillage shows that DPH > SSR > DP > OX > HTR > H, with values ranging from 0.75 Mg ha-1 to 1.46 Mg ha-1 (P < 0.05). Intercropping reduced the seasonal means of bean grain yields (P < 0.05) with a 54 % decrease by intercropping (0.73 Mg ha-1) compared to the sole bean (1.6 Mg ha-1). Thus, the DP and DPH improved crop yield and yield components and can be recommended as tillage practices in the semi-arid region.

The present study evaluated in vitro and in vivo anthelmintic (AH) effect of the percolated by-product of Coffea arabica against a Haemonchus contortus isolate with low susceptibility to tannins. Firstly, the susceptibility to tannins of Paraíso H. contortus isolate was evaluated with the in vitro larval exsheathment inhibition assay (LEIA) using an acetone:water (70:30) extract of Acacia pennatula. Afterwards, the in vitro AH effect of acetone:water extracts of percolated C. arabica by-products (Clean and Smooth (CS) and Shade Grown (SG) Starbucks®) were evaluated. Then, the in vivo AH effect was determined in growing sheep (4 months old and 15.2 kg bodyweight), infected with H. contortus (Paraiso isolate) and fed with a diet containing the percolated by-product of C. arabica. Three experimental groups were formed (n = 6 lambs): GC Group (control diet without C. arabica), GCA Group (feed containing 10% C. arabica) and, GCA+PEG (polyethilenglycol) Group (feed with 10% C. arabica + PEG as a tannin inhibitor). Fecal samples were obtained daily from the rectum of lambs (days 1 to 20 of the study). The H. contortus isolate tolerated the A. pennatula extract at concentrations of 150 and 300 μg extract/ml PBS (P > 0.05), which confirmed its low susceptibility to tannins. The C. arabica CS extract reduced the exsheatment from 150 μg of extract/ml PBS and the SG variety from 1200 μg of extract/ml PBS (P<0.05). The consumption of the C. arabica percolated by-product did not reduce the egg excretion of H. contortus (either per gram of feces or total eggs in feces) (P>0.05). In conclusion, the C. arabica percolated by-product extracts showed in vitro AH effect against exsheathment. However, the consumption of feed containing 10% of the percolated by-product did not show an in vivo AH effect in sheep infected with the Paraiso H. contortus isolate. The latter could be due to the low susceptibility towards the secondary compounds of tannin rich plants of the H. contortus isolate used in this study.

Soil aggregation is a key short term indicators of soil quality attributed to changes in land management. A study was conducted to investigate changes in the size distribution and stability of soil aggregates in a structurally unstable sandy loam soil following cultivation of Brachiaria grass in semi-arid region of Kenya. Brachiaria grass cultivars included Brachiaria decumbens cv. Basilisk, B. brizantha cvs Marandu, MG4, Piata and Xaraes, B. humidicola cv. Llanero and B. hybrid cv. Mulato II which were compared with two locally cultivated forage grasses (Chloris gayana cv. KAT R3 and Pennisetum purpureum cv. Kakamega 1) and a bare plot (negative check). The grass treatments were evaluated with fertilisers application (40 kg P applied at sowing and 50 kg N ha−1 in each wet season) and with no fertiliser applications. Aggregate size fractions were isolated using the wet sieving method. Aggregation based on the proportion of small macro-aggregates (250–2000 μm) increased in soils cultivated with all grass types compared to the control and was greatest in soils under B. hybrid cv. Mulato II. Aggregate stability in terms of mean weight diameter (MWD) differed among the grasses and was highest in soils under cv. Mulato II and cv. Marandu with MWD of 4.49 and 4.31 mm, respectively. Changes in small macro-aggregates fraction was positively correlated with particulate organic matter (POM) (r=0.9104, P= 0.001), microbial biomass carbon (MBC) (r=0.5474, P= 0.01), soil organic carbon (SOC) (r=0.3654, P= 0.05) and root biomass (r=0.4977, P= 0.01). This indicated that the binding agents were important in the aggregation of soils cultivated with Brachiaria grasses.

Results of the nutritional content of some consumed plants species by goats (Capra hircus) in San Gabriel Casa Blanca in the Cañada region within the Tehuacán-Cuicatlán Biosphere Reserve are reported. In November 2012 (rainy season) and May 2013 (dry season) 16 plants species commonly consumed by goats were collected. The parameters determined were crude protein, dry matter, ash, crude fat, crude fiber, neutral detergent fiber, acid detergent fiber, calcium, phosphorus, in vitro dry matter digestibility and metabolizable energy. The results were compared by multivariate analysis. From the rainy season analyzed species Ceiba parvifolia, Waltheria indica, Prosopis leavigata, Solanum sp. and Sanvitalia procumbens contributed with high content of crude protein, acid detergent fiber, nitrogen-free extract, phosphorus and crude fat; while in the dry season Acacia farnesiana, Prosopis leavigata and Ziziphus pedunculata were important source of crude protein, metabolizable energy and in vitro dry matter digestibility. These results may have implications for management goats in the study region.

Published: December 2023

The purpose of this study was to assess the effect of charcoal production and use on the transition to a green economy in Kenya. This study identified the target tree species that are a source of charcoal consumed in Nairobi city, determined quantity of charcoal consumed in the city of Nairobi and estimated forest cover depletion from charcoal production and use. The study adopted a research survey design involving the use of semi-structured questionnaire, with a target of 100 respondents (20 large scale charcoal traders and 80 charcoal users) sampled through person-to-person interview, selected using a purposive/systematic random sampling technique. Descriptive statistical data techniques were used to analyze the field data. The findings revealed that about 1264 ha and 15174 ha of forest cover are depleted on monthly and yearly basis respectively. Forest cover depletion is predicted by charcoal consumption. The study also revealed that Kenya would lose about 65.6% of its forest cover to charcoal production and use by 2030. Taking measures to propagate the most preferred Acacia species and ensuring massive tree planting exercise especially in order to protect arid areas of the country is important. Legislations on charcoal, reforestation/afforestation should be reinforced nation-wide if Kenya hopes to transition to a green economy within its vision 2030 agenda.

There are a few reasons that can lead to food security, such as natural disasters, rising food prices, population growth, climate change, and wars between countries. FAMA is one of the government arms under the Ministry of Agricultural and Food Industries (MAFI) assigned to counter this issue. Indeed, FAMA has put forward some initiatives to balance this never-ending issue, but on the other side of the coin, there still exist imperfections that could hamper the initiative earlier if not dealt with carefully. This editorial note intends to examine the initiative and its shortcomings from the grassroots perspective.

Malaysia received permission to export frozen whole durian to China in August 2018. The cryogenic freezing method is proposed for use as it is one of the best techniques to supply and preserve the quality of durians all year round. Since this method is newly established and still needs to be validated during simulation and export trials, a standard operating procedure (SOP) needs to be developed to ensure the quality of whole fruit durian is preserved. A procedure comprised of sanitation treatment, cryogenic freezing, low-temperature handling, and methods for thawing frozen whole durian had been developed. The proposed disinfection treatment using sodium hypochlorite is recommended in the protocol to ensure it is free from any quarantine pests of concern to China. Furthermore, cryogenic freezing between -80 °C to -110 °C was introduced in the protocol as a treatment to prolong the storage life of Malaysian durian for exporting whole fruit form to China. An export trial was performed to validate the handling of the frozen durian in a cold chain (-18 °C) maintained until it reached the retail end. The thawing technique for frozen durian was studied in the lab and during the export trial to confirm the best eating quality. All these become a standard operating procedure to ensure Malaysian durian is safe to eat, handled in a controlled condition, and served at the best eating quality as a premium product of Malaysia.
A Perspective of Food Security, Marketing and the Role of the Government
Authors:   Federal Agricultural Marketing Authority (FAMA), Malaysia, Abd Razak Abd Razzif
Published: December 2023

Food security is attained when individuals possess both the physical means and financial resources to consistently obtain an adequate supply of food that fulfils their nutritional needs, so enabling them to maintain optimal health and productivity. The four fundamental dimensions of food security that are widely acknowledged are availability, accessibility, stability, and utilisation. The concept of food security is difficult to define and grasp. Nevertheless, the consumption of an adequate quantity of food on a consistent basis is a fundamental physiological requirement for individuals, which is expected to influence household behaviour in both the public and private sectors. The available evidence indicates that governmental policy measures aimed at addressing concerns related to food security have exerted a substantial influence on the economies of countries where a considerable proportion of the population experiences undernourishment, both at the individual family level and within the broader context of national markets. The provision of food security by the public sector has transformed from being a crucial economic stimulant in many prosperous emerging countries to becoming a political reaction to the challenges posed by swift structural transformations. The correlation between economic growth and food security often transitions from a positive association to a negative one. Given the projected increase of three billion individuals by the year 2050, the following concepts aim to tackle the urgent challenges pertaining to supply and demand. Food insecurity is a highly challenging global concern. Nevertheless, the concept of food security encompasses a supplementary and less precise dimension. This article examines the perspective of food security, marketing, and the role of the government in addressing food-related concerns.
Type 2 diabetes mellitus-associated cognitive impairment and management
Authors: Swarnkar Priyanka , Rajput Prabha
Published: December 2023

Diabetes mellitus (DM) is a complex metabolic condition characterized by persistent hyperglycemia and poor metabolism due to insulin production irregularities and/or insulin resistance type 2 DM (T2DM) and dementia are linked through a variety of methods. Thus, in terms of the long-term repercussions of diabetes, the current idea focuses on cognitive damage, the exact pathophysiology of which is unknown. A new term, “diabetes-associated cognitive decline,” has recently been proposed to aid study in this field. This review discusses how different variables contribute to the development of T2DM. Furthermore, we investigated an expanding body of literature on insulin signaling in diabetics, as well as various factors such as insulin resistance, hyperglycemia, neuroinflammation, and Aβ (amyloid beta) plaques that may act alone or in combination to link T2DM with cognitive impairments. Finally, we looked at how physical activity and a balanced diet might help fight the condition.
Recent updates on analysis of alteration of Zn level in cancer patients
Authors: Singh Alamjot , Dagar Komal , Asati Vivek
Published: December 2023

Zn micronutrient is involved in many physiological processes that include enzyme activity, genomic stability, DNA repairing, apoptosis, immunity, neurological function, response to oxidative stress, and cell signaling. The deficiency of trace element Zn may be responsible for the mutation of DNA, tumor genesis, and carcinoma cell production. The Zn level has been found to decrease in cancer patients as compared to the healthy controls. Various cancer such as breast, ovarian, prostate, lung, Ewing, endometrial, brain, and bladder cancer have been correlated with Zinc deficiency. The polymorphism may be correlated with the ZINC deficiency in several cancer patients. The polymorphism has been observed in MT2A, Matrix metalloproteinase (MMP)-1, MMP-2, MMP-7, and MMP-13 genes significantly change in the Zn levels in the serum of prostate cancer patients. The genotypes GSTM1 and GSTT1 significantly change the concentration of zinc concentration in lung cancer patients. The presence of polymorphism rs1805502 in the GRIN2B gene within the brain is associated with a notably reduced concentration of zinc in the serum. The results of these studies associated with deficiency of zinc in the body may cause DNA damage, mutation in DNA, and tumor growth. This review article provides a detailed description of the deficiency of the Zn element in cancer patients and polymorphisms in genes encoding zinc-dependent proteins associated with different cancers.

Pengembangan kompetensi merupakan cara untuk mengkorelasikan antara kompetensi pegawai dengan organisasi. Bahkan organisasi global pun melakukan hal demikian. Pengembangan kompetensi dilakukan juga di instansi pemerintah. Bahkan PNS memiliki porsi pengembangan kompetensi yang besar, minimal 20JP pertahun. Pengembangan kompetensi PNS dilakukan untuk mengisi kesenjangan kompetensi PNS dengan standar kompeteni jabatan. Sedangkan disisi lain, PPPK memiliki alokasi pengembangan kompetensi yang terbatas, hanya maksimal 24 jam dalam satu tahun. Disisi lain, rekrutmen PPPK saat ini belum sepenuhnya ideal. PPPK berasal dariperalihan tenaga honorer dan kontrak yang lulus seleksi PPPK. Sedangkan amanat kebijakan, pengembangan kompetensi PPPK hanya digunakan untuk pengayaan kompetensi teknis. Metodologi yang digunakan dalam tulisan ini adalah deskriptif kualitatif dengan menggunakan teknis studi literatur dari peraturan perundangan, buku dan jurnal. Hasil analisis menunjukkan bahwa pelaksanaan pengembangan kompetensi PPPK memiliki tantangan. Pengembangan kompetensi yang bertujuan untuk mengisi gap kompetensi dan diperuntukkan bagi PNS juga dibutuhkan oleh PPPK. Oleh sebab itu dapat dilakukan diversifikasi pengembangan kompetensi PPPK. Salah satunya memberi ruang untuk pengembangan kompetensi teknis lebih banyak dari amanat kebijakan. Memaksimalkan knowledge management dan pembelajaran mandiri juga menjadi salah satu solusi untuk mengatasi keterbatasan ruang pengembangan kompetensi PPPK.

Um só, três filmes:
Authors: Cunha João Fabricio Flores da
Published: December 2023

Um só, três filmes propõe-se a investigar a produção de sentido na Trilogia das Cores, do diretor polonês Krzysztof Kieślowski (1941-1996), a partir das relações entre os filmes que a compõem. O objetivo é entender como eles operam na constituição da trilogia e defender a tese de que há um só filme, cujos sentidos tornam-se transparentes justamente conforme as relações que podem ser percebidas entre aspectos ora recorrentes ora dissonantes presentes em cada um dos filmes. Para tanto, problematiza-se a noção de trilogia em séries diacrônicas para, ao adotar a perspectiva da sincronia, identificar cenas dos três filmes cujos sentidos somente podem ser alcançados quando postas em relação intersemiótica.

Apontamos que a cobertura jornalística se restringe a cinco categorias temáticas, que priorizam notícias de serviço (vagas de emprego, divulgação de eventos, pautas sociais, legislação e problemáticas da falta de acessibilidade arquitetônica). Assim, compreendemos que a cobertura jornalística sobre a temática é insuficiente e restrita.
Em busca das características de Tom Wolfe em textos do Novo Jornalismo
Authors: Zibordi Marcos Antônio
Published: December 2023

Este artigo apresenta resultados finais e inéditos de pesquisa de pós-doutorado que verificou a presumível presença, em livros-reportagem, das quatro características do “novo jornalismo” que, segundo Tom Wolfe (2005), caracterizariam tais obras. Verificamos, empiricamente, que elas não estão identificados: a narração não ocorre alternando cenas; os narradores não são personagens; os diálogos são raros; e os detalhes significativos, quando existem, dificilmente podem ser qualificados como estritamente realistas ou literários. Tais aspectos poderiam atribuir literariedade às longas narrativas jornalísticas, mas foram pouco explorados nas obras analisadas.

O objetivo deste artigo é refletir sobre as relações entre subjetividade, visibilidade e mídias sociais a fim de compreender o papel dos influenciadores digitais nas práticas da comunicação digital e na cultura contemporânea para além de uma função profissional e comercial. A partir de revisão bibliográfica e da análise de exemplos coletados com base em observação espontânea no Instagram, buscamos entender os influenciadores não somente como um novo tipo de profissional, mas também como um modelo de subjetividade contemporâneo. Como resultado, propomos o conceito de selfie influencer para pensar os influenciadores digitais enquanto um personagem-sintoma da subjetividade contemporânea na comunicação digital, que combina os traços do self empreendedor neoliberal a uma competência midiática, influenciando não apenas decisões de consumo, mas estimulando novos modos de ação e autogestão.
Investigating the Point of View of Project Management Practitioners on Technical Debt - A Study on Stack Exchange
Authors: Gomes Felipe , Santos Eder , Freire Sávio , Mendes Thiago Souto , Mendonça Manoel , Spínola Rodrigo
Published: December 2023

Context: Technical debt (TD) can bring short-term benefits to software projects, but its presence is associated with issues such as decreasing product quality. Recent literature has proposed various approaches for identifying and managing TD, but most of them focus on the software developers’ point of view. Little is known about how project management practitioners perceive and manage TD items. Goal: This work aims to investigate how project management practitioners discuss and experience TD. Method: To achieve this goal, our work mines, curates, and selects a total of 108 TD-related discussions on the Stack Exchange Project Management (SEPM) Q&A site. These discussions amount to 547 posts and 882 text comments on the subject. We analyze this data set quantitatively and qualitatively, using open coding to derive TD types, indicators, and management practices. Results: We identified 74 indicators used for recognizing debt items and 126 TD management practices. The types of debt most discussed at SEPM are process and people debts. This contradicts studies done with developers where code and design debts are most discussed. Conclusion: The perspective considered by project management practitioners to analyze the TD phenomenon is different from the one considered by other roles in the software development process. Our work organizes the identified TD indicators and management practices into a Sankey diagram, which may assist TD management practitioners and serve as guidance for future research on the subject.
Simulation-supported development for cooperative Multi-UAV Systems with the Mysterio framework
Authors: Nascimento Cavalcante Antônio Sávio , Nicolau de França Breno Bernard
Published: December 2023

Over the years, UAVs (also known as drones) have been growing in studies and applications to solve diverse problems. Due to the complexity of these problems, dealing with just one UAV may not be enough, but using several UAVs together to work cooperatively increases its capacities, thus boosting innovative solutions. However, developing cooperative Multi-UAV systems is not trivial, and reuse support is usually limited to low-level implementation. This work presents a framework for Multi-UAVs, called Mysterio, which provides an underlying software architecture with essential Multi-UAV components, enabling the reuse of design and code so that engineers can instantiate it to carry out specific missions by making UAVs work in cooperation. We also present four instances of the framework to evaluate Mysterio’s effectiveness in different scenarios. Finally, we discuss the framework’s potential to provide and support design and code reuse to develop Cooperative Multi-UAVs systems for different application scenarios. The results showed the potential to develop multi-UAV systems using the proposed framework. Additionally, we extend our previous work bringing conceptual evolution and advances in the architecture and the framework. Finally, this evolution extends the framework API to support computer simulations of UAV systems based on the OMNeT++ simulator. This API is suitable for Single-UAV and Multi-UAV systems and has already been adapted to communicate with base stations implemented through the Mysterio Framework.

Authors: Ram Mayur , S. Desai Bimal , S. Jha Sumankumar
Published: December 2023

Commonly called as Indian Cheese Maker, Paneer dodi, Paneer phool and Vegetable rennet, Withania coagualans belongs to family Solanaceae and widely used in Indian System of Medicines due to its anti-diabetic, anti-microbial and immune modulator properties. The specific epithet coagulans reveals its coagulating properties and hence used in Punjab and parts of Northern India in cheese and paneer industries. The plant is rich in enzyme Withanin which is responsible for the coagulating properties. Many herbal prescriptions like Liv 52, (Liver Health Support Supplement) which is an Ayurvedic poly herbal formulation consists of extracts of both Withania somnifera and Withania coagulans. Commercial cultivation of this plant is in its initial phase in parts of Punjab, Haryana and also in neighboring countries as it has wide distribution extending up to South Asia. Plant is also rich in Withanolide contents and can be a future prospect for South Gujarat region, as coagulating agent for dairy industries and rennet enzyme production. Seeds are available in local markets of Surat and Navsari, routinely used for controlling diabetes. The chapter aims at the possibilities of cultivating this plant in South Gujarat conditions in India, since the other species Withania somnifera is also available and has naturalized in AES Zone III of South Gujarat.
Mitigating the Effects of COVID-19 through Vaccination: Evaluating Leading Countries across Continents of the World

Published: December 2023

This research investigates COVID-19 vaccine efficacy across six countries: India, South Africa, France, Australia, the USA, and Brazil, examining their impact on reducing deaths and containing the virus. It analyzes vital epidemiological metrics during pre-vaccination and post-vaccination periods until February 5, 2023. The countries are grouped by their Aridity Index, reflecting climate variations. Employing Pearson correlation, the study explores the relationship between the Aridity Index and vaccination period rates, noting some moderate associations but lacking statistical significance at a 5% level. Comparing case fatality and infection rates before and during vaccination showed no significant differences. However, incidence rates displayed a notable discrepancy at the 5% significance level. The study underscores the need for non-pharmaceutical measures alongside vaccination efforts to mitigate the increase in incidence and infection rates. It emphasizes that while COVID-19 vaccinations play a crucial role, complementary measures remain essential in effectively managing the pandemic. Overall, this research offers critical insights into vaccine efficacy across diverse countries, advocating a continued multi-faceted approach to combat the global health crisis.

Authors: Ciecińska Barbara
Published: December 2023

The chapter briefly presents the issue of quality and its management in production. In the relevant part of the chapter, the Ishikawa diagram, its variations, and the possibility of extending its application to new areas will be discussed. Similarly, the 5 Whys method is presented. The application of the Ishikawa diagram and how to use the 5 WHYS method are presented with practical examples, enabling them to be transferred to the operation of real enterprises. These examples concern machining, laser processing, and gluing in the context of defective products and processes. The discussion includes case studies of what defects may appear in this type of (or similar, in the field of mechanical engineering) processes, a discussion of their importance in production. Ways to improve machining and assembly operations in the presented context are shown.
Fairer for all: Teachers identifying and solving problems with the assessment of English language learners in the mainstream classroom
Authors:   Waipapa Taumata Rau |University of Auckland, Erlam Rosemary
Published: December 2023

The emphasis in classroom-based assessment on assessment for learning means that the classroom teacher now bears greater responsibility for assessment (Malone, 2008). The success of any assessment process depends on the skill the teacher brings to classroom assessment and their ability to make decisions which are appropriate for their specific learners in their particular contexts (Hill, 2017). This paper focuses on three teachers who conducted an inquiry into an aspect of assessment practice in their teaching context. These inquiries are examined through two theoretical frameworks. The first uses Hill’s (2017) Teacher assessment literacy framework to illustrate how teachers’ reflections on the three dimensions of oning of assessment practices. The second uses the Assessment Use Argument which outlines the steps which need to be taken to justify or challenge the use of a given assessment. The paper documents the problems that these three teachers identified at different stages of this argument sequence. Through conducting these inquiries the teachers realized that specific assessments used in the mainstream classroom were not valid when used with English language learners (ELLs). They drew conclusions and proposed adaptations, thus demonstrating that teachers can make appropriate assessment decisions to ensure fairer outcomes for these learners in their local contexts.

Phantom young English language learners: The shadowy presence of second language proficiency in (English medium) early childhood assessment
Authors:   Australian National University, Angelo Denise , Hudson Catherine ,   Australian National University
Published: December 2023

This paper examines how English language learners (ELLs) remain shadowy figures in the Australian Early Development Census (AEDC), a national early childhood development assessment, which since 2009 has been completed triennially by classroom teachers in all Australian jurisdictions for every child in their first year of schooling. It shows how ELLs elude clear identification and appropriate English as a Second/Additional language (L2) assessment because of the fundamentally monolingual conceptualisation of this tool. The AEDC provides the only set of education data at the national level for this young age group and has consequently become a “go to” measure for policy initiatives. However, young children in contemporary Australia are linguistically diverse and so semi-recognition of ELLs in an English only assessment tool is very concerning. Neither the definition of ELLs nor the wording of key assessment items gives classroom teachers sufficient guidance on how to respond for ELLs. The resulting AEDC data and associated reports easily drift towards deficit misinterpretations as natural L2 proficiency levels are muddled with global childhood development in communication and cognition. The paper makes recommendations for improving the quality and accuracy of AEDC data outputs for ELLs and for using the data for policy purposes.
