Gender politics, UK jazz festivals and COVID-19
Authors: Raine Sarah
Published: December 2021

Music festivals offer a valuable glimpse into the state of the current musical landscape. Through them we can follow the career trajectories of particular artists, spot genre trends and divergences, identify connections and differences, and make sense of emerging scenes. Equally, music festivals lay bare the continued inequalities that exist; inclusions and absences are starkly visible in festival line-ups, and marketing and communications provide inspiration for public debate and the fuel for change. For scholars, festivals offer a context through which to examine the complex politics of music, condensed into a specific time and place yet engaging with global trends and debates, with international artists and audiences, with the past and the future, all within the economic and social context of the music industries. From spring 2020, we could clearly plot through music festivals the global impact of the COVID-19 pandemic on live music as we have previously known it, the government-driven lockdowns and social distancing regulations bringing an abrupt halt to live performance and threatening the existence of many music festivals. This period of disruption extended also to the outreach, education, artist development, fundraising, partnership working, and overall strategies of festival teams, to include festival-driven and global attempts to address significant issues relating to access and diversity within the music industries. This article explores gender politics from the stage of UK jazz festivals and considers the momentum of gender-focused initiatives during a period of international crisis.

Published: December 2021

In rural society, though technology use is one aspect of social justice, bringing hope to the hopeless can be facilitated by use of technology to improve their quality of life. Technology could enhance their capabilities and encourage their participation in the process of development. But the promotion of technology can not be accelerated unless a climate of receptivity and an awareness of the importance of technology in modern life are created in the general public. Use of local resources and skills for the design and development of technologies would be helpful towards their speedy acceptance and adoption. The present study was undertaken in Chandragiri and Ramachandrapuram Mandals of Chittoor district of Andhra Pradesh. The total sampling technique was adopted in the selection of respondents. A structured interview schedule prepared based on the objectives of the study, was used for collecting primary data. The major findings of the study showed that one third of the respondents were in the age group of 30-39 years. 84 per cent of the respondents were married. 41 per cent of the respondents were illiterates. Majority of the respondents belonged to the nuclear family system. 38 per cent of the respondents belonged to the income group of Rs. 2001-3000 per month. 85 per cent of the respondents were using modern kitchen ware technologies which enable them to cook quickly and comfortably.

Authors: Bharti Kusum , Kumar Manoj , Prasad Pramila
Published: December 2021

Nutritional requirements peak during adolescence and, in absolute terms, are higher than at any other stage of life. Malnutrition at this stage leads to stunting of growth, repeated infections and places constraints on full physical and psychological development. The current nutritional status of the population reflects the lack of progress over time, despite a number of national level programmes and policies.Objective: The main objective of the research study were to assess the dietary intake and pattern and their Nutritional status of non-school going and school going AGLs the age group of 11-14 yrs, enrolled at AWCs under SABLA Scheme of Banka District. Method: For this study, Anthropometry measurement, 24h dietary recall method including Take Home Rashan of SABLA programme, SABLA Kishori Card Observation and Questionnaire method as tools were used. Result: The obtained data explains that dietary intake of both major groups was not satisfactory within the Kcal of 1500-2000, 10% Adolescent Girls were fortunate enough to get their diet according to RDA. No any remarkable differences have been found in the dietary intake of school going and non-school going girls in both groups i.e. 11-14 and 14-18 years of Adolescents girls. The Dietary intake and pattern were found the same. the findings on the nutrition intake especially in micronutrients make it obvious that there was no difference in nutrition intake of both the major groups i.e. School going and Non-school going AGLs. Actually, speaking more than 70% AGLs of the both the group were not getting sufficient amount of macro and micro nutrition. most significant food stuff for vulnerable group of adolescent age – the consumption of Pulses, GLF, Milk, Fruit, Egg/Meat/ Fish, was very poor. As we know the fact how valuable these food stuffs are for the physical and metal development of the AGLs.

Work-related ergonomic study among egg sellers- a study carried out West Garo Hills, Meghalaya
Authors: Saikia Ranima
Published: December 2021

The study has investigated the drudgery index and the musculoskeletal discomfort perceived by the respondents engaged in activities related to selling of eggs in the hilly terrain of West Garo Hills, Meghalaya. Findings reveal that cleaning of eggs is most drudgery prone compared to other activities they perform. The activity demands the use of small muscles and continuous movement of the hand at wrist level while holding and cleaning the eggs by using paper/cloth. The activity of cleaning also demands more attention to avoid loss, as egg shells are more fragile. Moreover, the sellers felt discomfort at the mid back, lower back and buttocks due to prolong sitting posture they adopt and due to twisting of the body to reach the items kept at the sides and back. Thus, designing of functional work station is the need for this group of sellers so as to reduce the drudgery level to eliminate musculoskeletal disorders.

Authors: Aparna P. , Babu G. Prasad , Chaithanya B.H.
Published: December 2021

Mango the “King of fruits” is the most important fruit crop in India. Harvesting of the mangoes are done with different methods by Indian farmers like manual plucking, tree shaking or local harvesters which are manufactured by the farmers. The tree branches are shaken to speed up the harvesting, which results in post harvest losses due to the physical damage, stem end rot and sap bleeding in mangoes due to absence of pedicel. To overcome these local harvesting methods and to reduce to drudgery of the farmers Krishi Vigyan Kendra, Banavasi has introduced IIHR model for harvesting mangoes and conducted frontline demonstration in farmer’s field. Harvesting efficiency of different harvesters was studied in comparison to manual plucking and local made harvester was compared with that of Indian Institute of Horticultural Research, Bangalore (IIHR) model. Among all the methods IIHR model is found to have higher efficiency as compared to the local b models.

Field evaluation of Rot-fix for management of root rot disease of mulberry (Morus sp.)
Authors: Kumar P.M. Pratheesh
Published: December 2021

Mulberry is cultivated throughout India as a host plant of silkworm (Bombyx mori L.) reared for commercial production of silk. The quality of silk produced depends largely on the quality of leaf fed to silkworm. Various mulberry diseases limit quality and quantity of silk production affecting the economic return to the farmers. Among these, root rot caused by a group of fungi is a severe threat for mulberry leaf production, especially in southern states of India due to large scale mortality and enormous crop loss. Though many fungi are isolated from the infected root, Fusarium solani is the one frequently found associated with the disease. Chemical control with fungicides is not advisable due the environmental concern and toxicity to the soil and silkworm. Thus, recently a broad spectrum environment friendly formulation viz., Rotfix has been developed by the Central Sericultural Research & Training Institute, Mysore and recommended after limited on-farm and field trials. However its efficiency has not been evaluated at the farmers’ level in large scale. The present study has been conducted to evaluate the effect of Rot-fix in large scale in four southern states of India. The Rot-fix has been applied to the infected plants and their recovery has been studied. There was a high recovery (86.76-91.96%) of the infected plants after application of Rot-fix. Though the leaf yield was significantly (P<0.01) lower (2.48%) in the recovered plants in first crop, by the second crop the plants were recovered completely and started giving yield the statistically on par with untreated healthy plants. The study therefore recommends the use of Rot-fix in large scale for control of root rot disease of mulberry.

Free vibrations of a thin-walled curvilinear section of an oil-trunk pipeline during ground laying
Authors: Sokolov Vladimir , Razov Igorʹ , Maltseva Tatyana
Published: December 2021

In this article authors obtained solutions to determine the ground curved sections free vibrations of thin-walled large-diameter pipelines with a liquid flow, based on a geometrically nonlinear version of the
semi-momentless toroidal shells medium bending theory by V.Z. Vlasov and V.V. Novozhilov. The pipeline is a toroidal shell, the design scheme is presented in the form of a half torus. Angle β = 1800. The shell is laid on an elastic foundation and makes contact with the ground along a narrow strip. The problem of the soil pressure influence on the shell along a narrow strip is solved as a contact problem, using Fourier's series and an impulse function. The shell is exposed to the cooperative effect of the internal operating pressure, the liquid flowing pressure, the elastic soil foundation, and changes in the geometric characteristics. Motion equations of the middle shell surface are obtained taking into account the geometric and mechanical characteristics, and all the components of the shell material inertial forces. The hinged fastening of the shell ends is taken as the limiting condition. Using the semi-momentless shell theory assumptions, displacements in the longitudinal and circumferential directions are obtained. The solution to the problem of determining the free vibrations comes down to solving the problem of determining AB matrix values. The solutions obtained make it possible to determine the free vibrations frequencies at various wavenumbers values in the longitudinal and circumferential directions, and also make it possible to determine the internal operating pressure contribution, the soil bed coefficient, and geometric characteristics to the pipeline free vibrations frequencies.
Problems of maintaining high motivation of students to have Physical Education lessons at the stage of transition from primary general secondary school to basic general secondary school
Authors: Piskova Dina , Bogatikova Maria
Published: December 2021

The beginning of the adolescence period is characterized by restructuring of the motivational sphere of the personality and changes in the social situation in education. During this difficult period, Physical Education lessons for adolescents often turn into a routine, motivation for them ceases to develop. The authors presented the results of the study of the fifth graders’ motivation to have Physical Education lessons, developed the tasks of forming motivation when moving from the first stage of study to the second one according to the gender principle, since gender determines both the pace of psychological development of schoolchildren and the orientation of motivation, which also develops under the influence of interests actively formed in this period.
The authors showed that schoolchildren come to the basic general secondary school with a moderately positive force of motivation. Boys are at the emotional stage in the development of motivation, they have identified prerequisites for the formation of the constructive-active and
spiritual-creative orientation of motivation. The motivational sphere of girls is characterized by the socio-emotional orientation, is in the state of restructuring, has some shortage of relevant motives, what makes some threat to polymotivation in the future, is defined by integration of knowledge, activity, socio-personal and personal motives in the significant zone.
Common tasks in increasing motivation will be the formation of an idea of health and ways to preserve it, the formation of ideas of personal self-improvement, means of physical education for personal development.
For boys, the current tasks will be the formation of the spiritual and creative orientation, carried out on the basis of revealing the links between theoretical ideas about health and practical development and implementation of individual health programs for a healthy lifestyle.
For girls, expanding the field of relevant motives by transferring the motivational orientation from emotionally effective to socially effective or personality-effective on the basis of the differentiation of significant motives, training in socially prestigious ways of achieving recognition in a socially significant group through various types of health activities, focusing on individual psychological, morphofunctional and motor abilities. The authors proposed pedagogical means for solving these problems.
The Rediscovery Hypothesis: Language Models Need to Meet Linguistics
Authors: Nikoulina Vassilina , Tezekbayev Maxat , Kozhakhmet Nuradil , Babazhanova Madina , Gallé Matthias , Assylbekov Zhenisbek
Published: December 2021

There is an ongoing debate in the NLP community whether modern language models contain linguistic knowledge, recovered through so-called probes. In this paper, we study whether linguistic knowledge is a necessary condition for the good performance of modern language models, which we call the rediscovery hypothesis.

In the first place, we show that language models that are significantly compressed but perform well on their pretraining objectives retain good scores when probed for linguistic structures. This result supports the rediscovery hypothesis and leads to the second contribution of our paper: an information-theoretic framework that relates language modeling objectives with linguistic information. This framework also provides a metric to measure the impact of linguistic information on the word prediction task. We reinforce our analytical results with various experiments, both on synthetic and on real NLP tasks in English.
Quoi-sluices in French
Authors: Gotowski Megan
Published: December 2021

Sluicing has traditionally been analyzed as an operation involving wh-movement and deletion (Merchant 2001). French is a language that has both fronted and wh-in situ strategies; on the surface, however, it seems that French sluices do not involve (overt) movement, in spite of this being an available option. For nearly all wh-words, the in situ and moved forms are the same; the notable exception is que/quoi ‘what’— que is found in fronted wh-questions alone, while quoi is found in situ. In sluicing, only quoi surfaces, suggesting that French may be a challenge for the movement-and-deletion approach (Dagnac 2019).By formalizing an analysis within a late insertion approach to the syntax-morphology interface, I argue that not only do sluices in French involve full structure, but that these involve movement as well. I assume that the wh-word is initially represented in the syntactic derivation as an abstract feature bundle. The morphological form is determined in the mapping of syntax to morphology by locality-dependent Vocabulary Insertion (VI) rules that are sensitive to C. These rules apply only after ellipsis occurs. Additionally, following Thoms (2010), I argue that C is targeted in sluicing, and as a result sluicing destroys the context that would trigger que. In this way, French sluicing provides support for the idea that ellipsis is able to bleed morphological operations (Saab & Lipták 2016; among others). The benefit of this analysis is that it is able to capture sluicing in French, while simultaneously explaining the behavior of quoi more generally.

Gastrointestinal diseases are increasing every day throughout the world due to many exogenous and endogenous factors. The objective of this research was to evaluate the antiulcer effect of Illicium verum L. "star anise" against digestive damage in rats promoted by ethanol. The rats were randomized into 4 pools of 10 rats each. The pools were compared with ranitidine at a dose of 50 mg/kg. The gastric injury was induced by ethanol. The ulcer damage was perceived 4 hours after having induced the treatments. All injury was found in the region of the body and anthropyloric stomach of the animal. The results showed that the application of a dose of star anise extract plus ethanol obtained an 80.5% (p < 0.05) reduction of gastric lesions; while using a dose of ranitidine plus ethanol, a 60.01% reduction in damage was achieved. In our laboratory conditions, the application of a 500 mg/kg dose of star anise in rats demonstrated a positive effect.

Hypericum brasiliense is a medicinal herb that contains chemical compounds, which can be used in medicine as an analgesic, anti-inflammatory and antidepressant. The aim of the present work was to evaluate the influence of substrate type and the addition or absence of naphthaleneacetic acid (NAA) on the rooting of stem cuttings. To carry out the study, 10 cm cuttings were obtained from H. brasiliense plants that were maintained in greenhouses for one year. Fifty percent of these were subjected to hormonal treatments with NAA at a concentration of 100 mg kg-1 for 30 minutes and the rest did not receive this treatment. Subsequently, the cuttings were placed in 50 cm3 containers with the substrates sand, pine bark or perlite and different combinations of these. Sand alone or combined with perlite were the best substrates for inducing adventitious rhizogenesis and promoting shoot growth, and pine bark the least efficient. H. brasiliensis cuttings have a high root development capacity without the addition of NAA, but root development is affected by the type of substrate.

The effect of doses or sheets of water application by drip irrigation on the yield of Brassica oleracea var. capitata (col) and Brassica oleracea var. Italic (broccoli), at the Fruit and Oleric Research Center (CIFO) - Huánuco-Peru. The factorial design with 6 treatments and 2 repetitions was used, with three irrigations calculated at 80, 100 and 120% of the mean evaporative demand (ETo). Plant height, diameter, pellet weight and kilograms per hectare were evaluated. Appreciating a significant effect on the weight per plant, equatorial diameter, of the pellets and kilograms per hectare; coming to produce in the cabbage crop 49.66 t ha-1 in treatment T4 (Col-100) and in broccoli 11.14 t ha-1 in T1 (Broccoli-120). This indicates that for cabbage sheets no greater than 100% are required and for broccoli it is necessary to increase a sheet to 120% for the conditions of the inter-Andean valley (Huánuco) considering times of less precipitation.

The objective of the research was to evaluate the effect of Trichoderma viride «cepa Ts-3» and aqueous extract of neem seeds (Azadirachta indica A. Juss.) On the growth and development of tomato seedlings (Solanum lycopersicum L. cv. ‘Ulises’). The experiment was carried out at the University of Pinar del Río, Cuba. Four treatments were established: control (seedlings without inoculations), seedlings + T. viride, seedlings + neem and seedlings + T. viride + nim, distributed in a completely random design, under conditions of trays and substrate based on Ferralitic Yellowish soil (70%), peat (20%) and rice husk (10%). Biostimulant activity of T. viride «cepa Ts-3» was found on the fresh root mass of the seedlings of tomato cv. ‘Ulises’; while the application of the aqueous extract of neem seeds negatively affected the growth and vegetative development of this cultivar, with a reduction of more than 40% of the fresh and dry biomass, although its inhibitory effect decreased in seedlings inoculated with T. viride «cepa Ts-3». The multivariate analysis allowed to differentiate the seedlings treated only with extract from those obtained in the other treatments and showed the possibility of combining the use of the agroecological alternatives evaluated.

The present investigation was carried out in the Tumbes National Reserve (RNTumbes) to determine the existence of drought, as well as the areas that are under impact from moderate droughts to droughts with abnormal behavior. The objective of the present work was to compare the NDWI and NDDI drought indices and to elaborate thematic maps of the study area. Images were obtained from the United States Geological Survey (USGS), selected from 1986 to 2019. For the determination of drought, the NDWI and NDDI were used. For the NDWI, the areas were determined to analyze the drought behavior and the NDDI was determined for its comparison with the NDWI. The results of this study allow us to conclude on: a) Regarding the drought, the NDWI had values ​​that ranged from -0.5 to 0.7 in the RNTumbes, classifying it as a weak drought and low moisture content; and b) The NDDI in the Tumbes National Reserve reached values ​​between -1189.04 and 1312.02, allowing a classification as humid soils, although they are not at their maximum water storage capacity during the years of this multitemporal analysis.

The “Huarango” Prosopis limensis is a woody species of the Fabaceae family that is in the dry forest of Ica, of key importance in this ecosystem and considered for different reasons in a state of danger. The in vitro cultivation of seeds of this species is presented as an adequate conservation strategy, due to high multiplication rates it promotes, the economy in time and production costs, and the future possibilities of improvement and reforestation. The objective of this study is the establishment of an effective methodology for the optimal germination of stored seeds of this species. The seeds were obtained from 4 representative experimental accessions from the department of Ica, which were subjected to a physical scarification treatment, immersing them in hot water (70 °C) and leaving it at rest until reaching a temperature of 37 °C. After conventional sterilization processes, seeds were sown in basic M&S medium with vitamins thiamine HCl (1,0 mg/l) and m-inositol (100 mg/l), sucrose 2% and agar 0,6%, and incubated at 23 °C +/- 2 h, for a photoperiod of 16 light hours. At 24 days the CPUC-117 accession the germination percentage was in the range of close to 95%. The results of this work constitute the necessary precedent to initiate larger-scale in vitro micropropagation trials of “Huarango” for conservation purposes.

The use of cover crops can bring multiple advantages to agricultural production systems and soil properties. The aim of this study was to evaluate the short-term effect of clover (Medicago hispida G.) and green peas (Psium sativum L.) as living covers on the soil moisture and yield of quinoa at the localities of Patasucro, Qaqas, and Ccanis in Ayacucho, Peru. We used a randomized complete block design considering clover, pea, and a control without coverage as treatments. Means were compared using Tukey’s Test (α 0.05). We observed significant differences in quinoa yield in Qaqas locality, where sites with cover crops exceeded the control by 0.4 t ha-1 (clover) and 0.29 t ha-1 (pea). Further, soil moisture was significantly superior under clover in the localities of Qaqas and Patasucro, with values 3.97% and 1.02%, respectively, higher than control. Soil moisture under pea and the control were not statistically different. It is argued that the yield improvements of quinoa occurred due to the conservation of soil moisture caused by the shading effect of the covers
