Opportunities for Learning: Analysis of Czech Lower-Secondary Chemistry Textbook Tasks
Authors: Vojíř Karel , Rusek Martin
Published: September 2022

Tasks in Czech lower-secondary chemistry textbooks were analysed to describe their position in textbook chapters, required response type, overall task nature, as well as cognitive requirements. The results showed older textbooks contain task banks at the end of chapters suggest a transmissive teaching paradigm, whereas newer textbooks containing tasks within the chapters. As far as the nature of the tasks is concerned, a strong stereotypical genre was found in the chemistry textbooks. Most of the textbook tasks require open-ended answers and target: factual and conceptual knowledge remembering or procedure application. The authors therefore suggest several changes to the tasks, including their position in chapters, cognitive difficulty as well as the required response type in order to meet chemistry education goals.

Authors: Rusek Martin , Vojíř Karel , Bártová Iveta , Klečková Marta , Sirotek Vladimír , Štrofová Jitka
Published: September 2022

The research mapped chemistry-oriented university freshman students’ ability to solve chemical calculations. Their success was monitored based on several factors such as their faculty, field of studies, the type of calculation and the assignment type (word problem vs. formula). The results indicate a significant need to change the approach to teaching chemical calculations - the students were rather unsuccessful in the tasks. The obstacles they face include the ability to identify a problem, understand the concepts of calculation and appropriately adjust the correct use of the mathematical apparatus. These findings represent an impulse for teaching in upper-secondary school as well as to introductory university courses.
Removal of Diazo Dye Direct Red 28 and Tetra Azo Dye Direct Black 22 Using Synthesized Magnetic Kaolin Supported Zinc Ferrite
Authors: Fındık Serap
Published: September 2022

The presence of dye molecules in water resources has harmful effects on environment. Therefore, it is important to remove dyes from wastewater using eco-friendly materials. In this study, adsorptive removal of diazo dye Direct Red 28 (DR-28) and tetra azo dye Direct Black 22 (DB-22) was investigated by using a new composite, kaolin supported zinc ferrite (KZF) as adsorbent. Characteristics of the composite, KZF were determined using various techniques such as FTIR, SEM, XRD, VSM, and EDS/Mapping. The adsorption of DR-28 and DB-22 on KZF was studied as a function of contact time, initial dye concentration, adsorbent amount, temperature, initial pH of the solution as well as the heat treatment of the composite. The removal of DR-28 was found to be 92.4% for the KZF concentration of 1g/200mL, initial dye concentration of 20 mg/L, contact time of 120 min at original pH and 21 °C. On the other hand the removal of DB-22 was found to be 91.7% under the same conditions at 40 °C. The results showed that Langmuir isotherm is suitable for the adsorption of DR-28 and DB-22 on KZF under given conditions. It was found that adsorption of DR-28 on KZF was exothermic while that of DB-22 was endothermic. The enthalpy changes (ΔH0) for the adsorption of DR-28 and DB-22 dyes on KZF were found to be –24.59 kJ/mol and 61.95 kJ/mol respectively. ΔS0 for the adsorption of DR-28 dye was found to be negative while ΔS0 for the adsorption of DB-22 was positive. The kinetic data fitted well to the pseudo second order model for the adsorption of DR-28 and DB-22 on KZF composite. These results showed that the prepared adsorbent KZF could be used as an adsorbent for the efficient removal of anionic dyes.

Published: September 2022

Rhodobacter is not capable of being transformed with pure, double-stranded DNA containing sites for endogenous restriction enzymes. The most efficient way of transfer of plasmid DNA to expression hosts is conjugation where single stranded DNA is transferred bypassing the hosts restriction system. The common E. coli strains used in cloning do not contains components necessary for the mobilization and transfer of plasmids via conjugal mating. In order to enable transfer of the expression vector to Rhodobacter hosts, an E coli host that is capable of conjugal mating (For e.g. S17-10 must be utilized).

Published: September 2022

The Paris Agreement, adopted in 2015, paved the way for a new hybrid global climate governance architecture with both bottom-up and top-down elements. While governments can choose individual climate goals and actions, a global stocktake and a ratcheting-up mechanism have been put in place with the overall aim to ensure that collective efforts will prevent increasing adverse impacts of climate change. Integrated assessment models show that current combined climate commitments and policies of national governments fall short of keeping global warming to 1.5 °C or 2 °C above preindustrial levels. Although major greenhouse gas emitters, such as China, the European Union, India, the United States under the Biden administration, and several other countries, have made new pledges to take more ambitious climate action, it is highly uncertain where global climate policy is heading. Scenarios in line with long-term temperature targets typically assume a simplistic and hardly realistic level of harmonization of climate policies across countries. Against this backdrop, this article develops four archetypes for the further evolution of the global climate governance architecture and matches them with existing sets of scenarios developed by integrated assessment models. By these means, the article identifies knowledge gaps in the current scenario literature and discusses possible research avenues to explore the pre-conditions for successful coordination of national policies towards achieving the long-term target stipulated in the Paris Agreement.
Emissions Lock-in, Capacity, and Public Opinion: How Insights From Political Science Can Inform Climate Modeling Efforts
Authors: Pianta Silvia , Brutschin Elina
Published: September 2022

The implementation of ambitious climate policies consistent with the goals of the Paris Agreement is fundamentally influenced by political dynamics. Yet, thus far, climate mitigation pathways developed by integrated assessment models (IAMs) have devoted limited attention to the political drivers of climate policymaking. Bringing together insights from the political science and socio-technical transitions literature, we summarize evidence on how emissions lock-in, capacity, and public opinion can shape climate policy ambition. We employ a set of indicators to describe how these three factors vary across countries and regions, highlighting context-specific challenges and enablers of climate policy ambition. We outline existing studies that incorporate political factors in IAMs and propose a framework to employ empirical data to build climate mitigation scenarios that incorporate political dynamics. Our findings show that there is substantial heterogeneity in key political drivers of climate policy ambition within IAM regions, calling for a more disaggregated regional grouping within models. Importantly, we highlight that the political challenges and enablers of climate policy ambition considerably vary across regions, suggesting that future modeling efforts incorporating political dynamics can significantly increase the realism of IAM scenarios.
Exploring Enablers for an Ambitious Coal Phaseout
Authors: Brutschin Elina , Schenuit Felix , Van Ruijven Bas , Riahi Keywan
Published: September 2022

To reach the mitigation goals of the Paris Agreement, many countries will have to phase out their coal power plants prematurely, i.e., before the end of their normal lifetimes, which will lead quite possibly to significant stranded assets. This could present a major challenge, particularly for many of the rapidly developing countries whose electricity demand is growing and which are currently expanding their coal fleets. Recent research shows that countries with aging power plants and decreasing coal consumption are more inclined to phase out coal, but little is known about where, why, and how coal power plants are being prematurely retired. In the context of the hybrid Paris Agreement, attention is increasingly shifting to domestic mitigation capacities and, alongside this—given the vested interests involved in different sectors—to state capacity to implement the transformations required to achieve deep decarbonization. In this article, we aim to study those capacities in the context of coal phaseout. We use a recent and comprehensive global dataset on coal power plants and employ a mixed-methods research design to (a) identify general emerging patterns with respect to premature coal fleet retirement, and (b) derive stylized types of political strategies to prematurely retire coal power plants. We find state capacity to be a robust predictor of general and premature coal retirement, and we identify three main strategies that countries have used to date to prematurely retire coal: (a) rein-in using top-down regulatory enforcement of environmental, climate, or other regulations that affect the operating licenses of coal plants; (b) buy-out or provision of compensation to companies and regions to appease vested interests; and (c) crowd out where accelerating market and price dynamics in the power sector crowd out coal. We propose that future research should explore more systematically the kinds of strategy that might be most promising in the regions and countries needing to rapidly phase out coal, taking into account their political structures, and also the implications that such strategies might have for global mitigation efforts.
Hearing Vocabulary as a Key Element for Image Creation in the Original Text and Its Translation (Based on the Short Story Butterfly’s Tongue by Manuel Rivas)
Authors:   Taras Shevchenko National University of Kyiv, KONDRATENKO Oleksandra
Published: September 2022

The paper sets out to provide a comprehensive description of the problem of reproducing the hearing vocabulary in the Ukrainian translation as it plays a key role in the image creation. The research is based on the data collected from the short story La lengua de las mariposas written by modern Spanish novelist Manuel Rivas since it’s been noted that this kind of lexis is used actively to describe, on one hand, the special atmosphere that was reigning in Spain at that time and, on the other hand, to specify the speech portrait of the characters. According to the results of the analysis, the main challenges in translation were identified. These are the physical sound description, visual images based on metaphors and epithets, phonetic peculiarities and euresemy cases. We have found out that when the verbal image with a hearing component is traced on the denotative meaning (that is to say, used to represent language world picture), there is no problem in establishing the direct correspondence between two languages. The major problems in reproducing this type of lexis are faced when it comprises such functional, stylistics connotations and associative features that differ from those that exist in the target language. Then the in-depth semantic structure analysis is needed that will determine the special translation transformations, for example the use of functional correspondence or neutralization of the figure. Furthermore, the background knowledge of the recipient must be considered as the sound terms may contain additional implicit information as well. But one should always be aware of the possible stylistic losses that may be a result of this or that transformation. The awareness of it will ensure the content unity of the text that is being translated.
Sociopragmatic Peculiarities of «Infodemic» in Arabic Social Media Discourse
Authors:   Taras Shevchenko National University of Kyiv, KUCHERENKO Alina
Published: September 2022

The term «infodemic» is nowadays used by the WHO to describe the excessive flows of inaccurate and unreliable data about the coronavirus both in the virtual and real worlds. This phenomenon is reflected in the social media posts containing the misleading information that involves fake news, rumours, nonchecked «facts», users’ thoughts, emotional reactions to different events, other online posts or messages. The previous researches include the creation of various Arabic Covid-19 misinformation datasets. However, a more in-depth analysis of the online discourse is needed due to the lack of its linguistic, sociolinguistic and communicative studies. This paper deals with the sociopragmatic aspect of the online communication in the Arab world during the Covid-19 pandemic. The communicants’ social features are presented within their Facebook and Twitter accounts. We manually collected nearly 100 online posts on Facebook and Twitter. We analysed the users’ communicative goals, and, especially, the linguistic tools utilized to achieve those goals, as well as the language variation caused by different communicative purposes of the «infodemic» posts. The key words of the data research are represented with the pandemic related lexemes of Twitter hashtags, such as kūrūnā «corona», liqāḥ «vaccine», dawāʼ «remedy», etc. We classified the studied publications according to the following topics: pharmaceutical companies’ profits; denial of the role of vaccination and the preventive measures; persuasion of the effective drugs existence; health tips. As speech acts, the studied posts involve such types as representatives (fake news, pseudofacts, etc.), directives (health advises), and expressives (attitudes, emotions, thoughts, etc.). On the other hand, the given texts are regarded as the acts of disagreement (explicit or implicit). The explicit means of negation is represented with the grammatical particles, meanwhile the implicit instruments include the lexis with the negative emotional expressivity or negative connotations. It was also noticed, that some male texts use the negative lexicon more frequently, than the female ones. The language variation reveals the relation between the post’s communicative purpose and the code choice (MSA is preferred for the representative posts (to demonstrate the credibility), ESA (Educated Spoken Arabic) is used in all types of «infodemic» posts, Colloquial Arabic as the language of everyday communication is mostly present in the expressives).
RESHAPING ALLIANCES AND REDRAWING BOUNDARIES: HOW INTERNATIONAL MIGRATION AFFECTED ITALIAN CIVIL SOCIETY
Authors: Santilli Cecilia , Scaramuzzino Roberto
Published: September 2022

Many conflicts in Italian politics have focused on migration policy. After the national elections in 2018, this conflict cut across all societal spheres and levels of governance and administration. On the one hand, tightening migration policies and criminalizing pro-migrant civil-society actors created a conflict between the government and many civil-society actors. On the other hand, civil-society and public-sector actors formed new alliances and lines of conflict at the local and national levels. This article analyzes the development of Italian civil society around the migration issue from the 1970s to 2019 from a relational perspective using the strategic action field approach. This approach offers a conceptual framework and an analytical model for studying behaviors and relations among different types of collective actors, including civil-society actors and public authorities.

Published: September 2022

Triply periodic minimal surface (TPMS) cellular structures of Ti6Al4V with theoretically calculated relative densities ranging from 4% to 22.6% were designed using a toolpath-based construction method and fabricated by laser powder bed fusion, and their macrostructure, microstructure, and compression performance were investigated. The results indicated that the macrostructure was the same as that of TPMS structures designed using the traditional method. In contrast, the microstructures of the as-built samples and the samples after stress-relief annealing were slightly different from those of the traditional ones. Moreover, compression test results of the Schwarz-P structures showed that the compressive modulus was positively related to the calculated relative density, and a Gibson-Ashby model was established to quantitatively describe the relationship between the compressive modulus and theoretical relative density. The findings of this work show that the mechanical performance of a TPMS structure obtained using a toolpath-based construction design can be accurately predicted using geometric parameters or printing toolpaths. This will be helpful during the design stage.

Authors: Gupta Swati , Abbas Alhamzah Fadhil , Srivastava Rajeev
Published: September 2022

The technology acceptance model (TAM) has long-term implications for management studies. However, the evolution of the literature on technology acceptance ideas received very little attention in the bibliographic review. Few research reviews provided a systematic overview of the development and progress of the TAM literature based on the entire citation network, while many research reviews focused on re-examining the links between TAM components through meta-analysis. This study investigates: a) how TAM research has evolved and expanded over the last 30 years; b) the main areas in which the TAM model has been used; and c) key contributors to TAM research and their collaborations. This bibliometric analysis was carried out based on 8207 papers published in the Scopus database between 1990 and 2020 to assess the feasibility of the model and its applicability. The findings revealed that early TAM research was conducted both by Eastern and Western scholars and that it has since continued to evolve and be shared widely. Nonetheless, most TAM publications have focused on the same narrow domains of computer science, social science, business, management, and accounting and the trendiest topics were usefulness, trust, ease of use, e-learning, adoption, e-commerce, and social media.

AIM: To explore the changes in lens thickness and density with age.
METHODS: A Chinese population-based retrospective study was performed. A total of 497 individuals (490 right eyes and 495 left eyes), ranging from 3 to 69 years old were included. Lens images obtained from IOL Master 700 were used to measure lens thickness and density. Piecewise regression model was chosen to illustrate the relationship of lens thickness and density with age.
RESULTS: The proportion of people aged 3-18, 19-40, over 40 was 38.6%, 50.9% and 10.5% respectively. The whole lens thickness decreased with age during the first 7 years of life, kept stable from 8 to 16 years old, and then increased at the rate of about 27 µm per year. The thickness of the lens cortex and nucleus tended to decrease first and then increase with age, which was dependent on age stages. The whole lens density also decreased with age until 7 years old. The increasing rate of lens density was different in different age groups. The whole lens density increased rapidly from 7 to 22 years old and slowed down after 22 years old. Similarly, the changing tendency of lens cortical and nuclear density differed in different age phases.
CONCLUSION: Both lens thickness and density are significantly associated with age, whereas they do not change linearly with age. Moreover, it is necessary to increase the population over 40 years old and conduct further research.

Published: September 2022

Quantum computing is becoming a major new field in engineering. Adaptation of classical computation concepts to this emerging technological reality is underway. In this study, a sampling-based approach is used to adapt state-domain equations to HHL-based formulation to obtain a homologous quantum algorithm for solving the dynamic equations in the state domain. The results obtained by the quantum computing approach are very close to the real response of the system and to the power-series-based exact solution. This work represents a significant contribution to the advancement of dynamic systems modeling and solving in state-domain adapted for use in quantum computers in the future.

Published: September 2022

The need of reducing the dependence of fossil fuels and CO2 emissions have motivated the diversification of energy matrix. Among the Renewables, the hydropower shows better characteristics compared to solar, wind, biomass and geothermal, because its low CO2 emissions, higher density and others technical factors. Within the Hydropower, the Hydrokinetic turbines (HT) are considered as a promising technology because can provide electricity during low flow velocity conditions (< 2 m/s) and is able to operate in shallow waters < 8 m and in secluded areas without access to the energy network. In this sense, the present study incentivizes the research in Hydropower and proposes and new application of DOE-ANOVA combined with Computational Fluid Dynamics (CFD) modelling for the HT design and optimization. Accordingly, this work evaluated the performance of a HT with 1.9 m of rotor diameter operating in a water flow of 1.5 m/s through a 23 factorial design with 9 modelling cases (MC). The results showed that the increment of outlet diameters increased the downstream velocity and the hydrodynamic pressure over the HT, and the reduction of the blade tip edge distance generated an increment of the response of the HT hydraulic and mechanical properties.

The aim of the present study was to evaluate the effect of equilibration process
on canine sperms after vitrification using coconut water extender with addition of soy
lecithin and sucrose as nonpermeable cryoprotectants. Twelve ejaculates were collected
separately by digital manipulation from 12 adult dogs. Only the second fraction of the
ejaculate was used in this study, which was evaluated about volume, concetration,
viability, total and progressive motility, kinetic parameters and morphology. After
evaluation, semen was diluted with a coconut water extender (50% coconut water (v/v),
25% (v/v) distilled water and 25% (v/v) 5% anhydrous monosodium citrate solution) with
addition of soy lecithin and fructose at 1% (v/v) and 0.25 M sucrose until final
concentration of 100x106 spermatozoa/ml. Samples were divided into three aliquots and
each of them was processed at different regimens: without equilibration, 5ºC for 30
minutes and 5ºC for 60 minutes and then vitrified by dropping 30 μl of sperm suspension
directly into liquid nitrogen. Sperm pellets were devitrified at least one week later as
three of them were dropped into 0.3 mL of CaniPlus AI (Minitüb, Germany), which was
previously warmed in a water bath at 37ºC for 2 minutes. Sperm concentration and
motility parameters were assayed using a computer-aided sperm analysis (CASA) system,
viability-by supravital staining technique and morphology parameters were evaluated in
Haemacolor® stained semen samples. In conclusion, our results demonstrate that when
vitrification and coconut water extender with addition of 1% soy lecithin and 0.25 M
sucrose as cryoprotectants were used, presence of equilibration time of 60 minutes
returned the best canine sperm quality results.

Published: September 2022

Equine chorionic gonatrophin (eCG) is a high molecular weight glycoprotein
produced by endometrial cups in the mare. ECG has primarily LH activity in the mare, but
has FSH or LH activity in the cow, depending on the recipient populations in the ovary.
Although eCG has been used to induce superovulation in a variety of species, several
studies have demonstrated the beneficial effects of eCG on fixed-time AI (IATF) programs
in beef and dairy cattle, and embryo recipients. Under these circumstances, eCG has
stimulated the development of the ovulatory dominant follicle and produced ovulation of
a larger follicle, resulting in a larger and more functional LC and longer embryo
survival. In suckling beef cows, 400 IU of eCG at the time of removal of a progesterone
device resulted in increased conception rates after IATF,and in dairy cattle managed in
pastoral systems, the eCG administration resulted in a significant increase in pregnancy
rates, especially in cows in anestrus. In embryo recipients, treatment with eCG has
resulted in increased pregnancy rates after embryo transfer. This presentation will
review some of this data and explore strategies to use the potential benefits of eCG to
improve bovine reproduction.

Published: September 2022

Cows that do not become pregnant during early lactation after successive
inseminations are usually classified as repeat-breeder cows. Furthermore, heat stress
has a pronounced deleterious effect on fertility in dairy herds throughout the world,
especially in hot and humid summer months in tropical and subtropical areas. Studies
describes the detrimental effect of heat stress on reproduction, with emphasis on carry
over effects of heat stress on oocyte quality, embryo development and P/AI.
Additionally, lower fertilization rate is also an important characteristic associated
with repeatbreeder cows. In repeat-breeder cows, decreased fertility has been related to
a deleterious effect on oocyte quality. Thus, the fertility problems observed in
repeat-breeder and heat stress cows may be related to poor oocyte quality associated
with a metabolic status. Studies support thar embryo transfer can be a practical and
effective solution to achieve pregnancy in repeat-breeder and heatstressed dairy cows
(with reduced oocyte quality and fertility to insemination).

Published: September 2022

Split Mastic Asphalt (SMA) mixture is mostly used on heavy traffic roads. SMA mixture has high percentage of coarse aggregate,  it is better able to withstand deformation due to heavy vehicles, and consist of high levels of asphalt, that makes the mixture more durable. High levels of asphalt in SMA require an additive as fiber, polymer, filler, and PET which functions to stabilize and increase the strength of the mixture. This study to determine the performance of the Split Mastic Asphalt mixture by adding kapuk fiber as an additive. The method used is a quantitative comparison of the marshall SMA test results without the addition of additives and the SMA mixture with the addition of cotton fiber as an additive. The variation of cotton fiber content used in the mixture is 0.01%, 0.025%, 0.05%, 0.075% and 0.1% of weight mixture. Based on the results of the study the addition of cotton fiber to the mixture can improve Marshall performance in terms of strength, density, and durability of the mixture. The strength of the mixture with the addition of cotton fiber will increase to the optimum limit, which is 0.075% cotton fiber. The density of the mixture (density) with the addition of cotton fiber will increase. Durability based on flow and MQ values decreased, but increased again at high cotton fiber levels, which is 0.1%

Campuran Split Mastic Asphalt merupakan campuran yang banyak digunakan pada jalan berlalulintas berat. Campuran SMA memiliki persentase agregat kasar tinggi sehingga lebih mampu menahan deformasi akibat kendaraan berat dan kadar aspal tinggi, sehingga campuran akan lebih tahan lama. Tingginya kadar aspal pada campuran SMA membutuhkan suatu aditif berupa serat, polimer, filler, dan PET yang berfungsi untuk menstabilkan dan meningkatkan kekuatan campuran. Penelitian ini bertujuan untuk mengetahui kinerja campuran Split Mastic Asphalt dengan penambahan serat kapuk sebagai aditif. Metode yang digunakan adalah perbandingan kuantitatif hasil pengujian marshall campuran SMA tanpa penambahan aditif dan campuran SMA dengan penambahan serat kapuk sebagai aditif. Variasi kadar serat kapuk yang digunakan pada campuran adalah 0,01%, 0,025%, 0,05%, 0,075% dan 0,1% terhadap berat campuran. Berdasarkan hasil penelitian penambahan serat kapuk terhadap campuran dapat meningkatkan kinerja marshall yang ditinjau dari kekuatan, kepadatan, dan keawetan campuran. Kekuatan campuran dengan penambahan serat kapuk akan semakin meningkat hingga pada batas optimum, yaitu 0,075% serat kapuk. Kepadatan campuran (density) dengan penambahan serat kapuk akan semakin meningkat hingga pada bata optimum penambahan 0,05 serat kapuk. Keawetan berdasarkan nilai flow dan MQ menurun, namun meningkat kembali pada kadar serat kapuk tinggi, yaitu 0,1%.

Authors: Archard Philip John , O'Reilly Michelle
Published: September 2022

This article adds to literature addressing research beneficence from a psychoanalytic perspective, providing reflections focussing on notions of containment and container-contained dynamics as derived from the Kleinian/post-Kleinian tradition of psychoanalysis. It does so by reference to the accounts of participants in a study which explored how professionals working in local authority children’s services in England experience the suffering of parents. In this research, a psychoanalytically informed interview approach was used, and space was provided for participants to reflect on the experience of participation. The variable representation of this experience is considered along with the experience of the researcher carrying out the interviews. Questions are raised about using the language of containment in the context of this research approach and whether this may say more about a researcher’s desire to be helpful to participants and less about participants’ actual experiences (and a genuinely psychoanalytically based understanding of them).

Enhancing Marginal Field Development Economics: Leasing Operated Production Facility Approach
Authors: Gupta Sumeet , Gupta Tushar
Published: September 2022

Innovative technical advances are now enabling operators to consider development of fields previously identified as uneconomic or marginal. However such projects can still fail to progress since development using a traditional engineering, procurement and construction (EPC) approach does not always meet the required targets for economics, risk and timescale necessary for approval to proceed. This paper will detail how the use of fit-for-purpose production facilities mobilized on a leased, operated and maintained basis now offers an alternative approach to the provision of a field production solution. This approach enables operators to limit their initial set up and infrastructure cost at the front end of a project, to gather additional information on the performance and productivity of their wells and to make a more informed decision on the future of the fields. As a result, operators can keep both their project and capital risk exposure to a minimum. By achieving this production on a fast track basis, revenue from the sale of produced well fluids is generated early. Combined with the low initial cost and lower capital risk of this approach, the economic viability of progressing an asset to full scale production is further enhanced. Based on this sequential investment model, a real option analysis of the overall field development plan can therefore make a project viable, even if the overall net present value (NPV) appears marginal using more traditional methods. In conclusion the research will present technical solutions for the various fields evaluation and production stages of a full field development utilizing the leased facility approach, associated commercial models and case studies for recently completed projects
Agricultural Trade Liberalization Reforms: Effects on Indian Agriculture and Agricultural Marketing Institutions
Authors: Dastagiri Madiga Bala
Published: September 2022

Worldwide, Governments have recognized the importance of liberalizing agriculture. The heart of the agriculture reforms lies in the â€˜market placeâ€™. This is basically a quick, diagnostic study illustrates firstly, the effects of WTO agreements and trade liberalization on Indian agriculture. Secondly, the effects of these reforms on mandates and functions of agricultural marketing institutions vis-Ã -vis the reforms and reorientation on happening in them in the context of trade liberalization regime in India. WTO agreements have mixed effects on agriculture of developing countries. Economic liberalization/ trade liberalization effects on Indian agriculture suggest that finance to agriculture by private sector has increased significantly. Production of food grains, non-food grains and all crops depicted a declining trend. Supply growth remains higher than growth in demand of cereals, fruits, vegetables except pulses and oilseeds. Marketed surplus and procurement prices of major staple cereals viz; paddy and wheat has shown an increasing trend. Aggregate measure of support (AMS) has decreased. Thus agricultural sector is now less protected and face stiff competition and higher price risks. Most of the functions of different agricultural marketing institutions relate to market regulation, development of infrastructure and administered prices are overlapping. The reforms in major areas of agricultural marketing sector at country level are matching with WTO liberalization requirements particularly in domestic markets, export and import, regulated markets, SPS measures and TRIPS. Some of the typical informal liberalized model markets such as alternative markets are already in operation. But some marketing institutions have been proactive in initiating reforms and marching towards commercialization

Published: September 2022

A cross-sectional study was conducted among commercial pig farmers in the Ejisu Municipality to investigate reproductive performance, piglet mortality, and reproductive health problems on their farms. Questionnaires designed to obtain information on reproductive performance and reproductive health problems were administered to a total of 50 randomly selected pig farmers. Three farms were randomly selected to monitor farrowing and pre-weaning piglet mortality. The farrowing records of a minimum of 10 sows on each farm were taken, and the piglets followed up to the point of weaning by six weeks. Records of piglet mortalities and their causes were retrieved from farm records or post mortem reports. The mean litter size, stillbirth per litter, piglet birth weight (Kg), weaning to estrus interval, and gestation period were 9.5± 1.4, 1.6 ± 0.2, 1.0 ± 0.1, .7±1.0 days, and 115.1± 2.6 days, respectively. The pre-weaning mortality (%) at day 42 was 18.7 and ranged from 7.3-28.3. Within the first two days post farrowing, mechanical crushing (8.9%) of piglets by sows and piglet starvation (7.2%), while diarrhea (2.5%) and piglet anemia (1.5%) accounted for mortalities within the first two weeks of life. Reproductive health problems by frequency of occurrence included mastitis (23%), agalactia (18%), stillbirths (18%), repeat breeders (14%) and dystocia (14%). The study concluded that the reproductive performance of sows was satisfactory, while pre-weaning piglet mortality was high. It is recommended to intensify extension education on the management of piglets after farrowing.
