Authors: Rajagopal Sivaranjani , Thondiath John Zachariah
Published: August 2023

An experiment was conducted at IISR, Kozhikode to study the effect of foliar application of chemical elicitors, namely, chitosan (100, 200 and 500 ppm), phenylalanine (0.1, 1 and 10 mM) and salicylic acid (0.01, 0.1 and 1 mM) on volatile constituents of turmeric rhizome essential oil (EO). Three genotypes (Pragati, Rajapuri and Acc.849) which vary in growth duration and volatile profile were taken for the study in randomized block design with three replications. The highest EO content in Pragati (6%) and Acc. 849 (5.3%) was found in Phenylalanine (1 mM) treatment. No significant changes in EO content were observed in the genotype Rajapuri. Phenylalanine and salicylic acid were found to have positive influence on ar-turmerone, the major sesquiterpenoid in Pragati. Acc.849 and Rajapuri did not produce any significant changes to ar-turmerone content in elicitor treated samples. Moreover, the treatment related variation in the total monoterpenes and total sesquiterpene content was found significant among the genotypes. Multivariate analysis using partial least square discriminant analysis supported the variation observed among the treatments and variable importance in projection scoreidentified the metabolites responsible for variation among treatments.

Published: August 2023

Meticulous analysis on intertwined interaction among the soil nutrients and microbial communities brings fruitful outcomes on horticulture. This study focuses on identifying well compatible bacterial genera in enhancing soil primary macro-nutrients for sustainable vegetable crops cultivation. The biochemical tests were executed for identification of bacterial genera. Eventually, mathematical models among available NPK nutrients (Nitrogen, Phosphorus and Potassium) and identified bacterial genera were derived to determine most suited bacterial genus for nutrients inhibition. This Study reveals the present nutrient’s status of soils at Anaimalai block covering 12,424 ha of Coimbatore district in Tamil Nadu. Seven utilitarian bacterial genera were identified which inhibit the plant nutrients. Among them, Azotobacter, Arthrobacter and Achromobacter actively inhibit available NPK in the soil. Present study of correlating soil nutrients with bacterial components enriches successful conservation of biosphere through adopting these innovative technologies in horticulture.

Published: August 2023

There is a huge potential for dragon fruits grown in India but insufficient information may hamper its production and postharvest handling. The aim of this study was to investigate the right harvest time and maturity indices for red and white pulp dragon fruit. Growth and developmental studies were undertaken using destructive (total soluble solids (TSS), titratable acidity and TSS: acid ratio) and non-destructive methods (fruit weight, specific gravity, peel colour and heat units). Fruits were collected at seven intervals (7, 14, 21, 26, 31, 36 and 41 days after flowering) to assess the right maturity. All these methods were used to standardize the optimum maturity and right time for the harvest of red and white pulp dragon fruit. Harvesting dragon fruits between 31-36 days after flowering (DAF) was found ideal for optimum maturity and quality. Both red and white pulp fruits harvested at 31 DAF showed better quality in terms of physic-chemical and sensory attributes.

Published: August 2023

Dashehari is the leading mango variety grown in Indo-Gangetic plain. Its yield is affected severely by the micronutrient deficiencies. Zinc and boron are the two important micronutrients which limit the yield and quality of Dashehari mango in this region. Hence a field study was taken up to understand the responses of Dashehari mango to different levels of Zn. Results indicated yield enhancement with proper Zn supplementation through foliar sprays. Highest yield of 43.50±2.00 to 50.72±2.40 kg tree-1 was recorded with 1.0% ZnSO4 application, followed by 42.27±1.26 (1.5% ZnSO4) to 47.85±1.65 (0.75% ZnSO4) kg tree-1. TSS (19.63±0.25 to 20.27±0.40°Brix), acidity (0.150±0.01 to 0.200±0.02%) and ascorbic acid (29.46±2.29 to 35.17±1.32 mg per 100 g) variations were noted under the influence of various Zn treated fruits. Foliar spray application also caused nutrient richness in mango fruit pulp showing improvement in Zn concentration in fruit pulp from 1.17±0.10 to 1.73±0.10 mg kg-1. Highest concentration of B, Cu, Fe and Mn were observed (3.13±0.018, 4.37±0.06, 7.87±0.06, 20.10±0.15 mg kg-1 respectively) with P and K concentrations of 0.026±0.0002 & 0.28±0.001% respectively. Significant difference in leaf and soil Zn content was also recorded. The results indicated that yield and quality of Dashehari mango can be improved with foliar spray of Zn in sandy loam soil.

Published: August 2023

Bael (Aegle marmelos (L) Correa) is an important underutilized fruit crop of India. A total of 25 bael trees were selected from 356 bael trees of Sakharayapattana in Chikkamagalur district, Karnataka, India based on the fruit morphological traits (fruit weight, pulp weight, skull thickness, seed weight per fruit, No. of seeds per fruit, No. of locules per fruit, No. of seeds per locule, pulp wt. : seed wt.). These 25 trees were evaluated for phenotypic and genotypic variations using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR) markers. RAPD and ISSR markers showed significant polymorphism among the trees. Jaccard’s genetic similarity value of RAPD and ISSR was found in the range of 0.00–0.95 and 0.06–0.56, respectively suggesting a moderate level of genetic diversity. The present study revealed that molecular markers can be successfully utilized for determining genetic diversity and relationship of bael trees for further varietal improvement.

Published: August 2023

An effective and rapid in vitro regeneration protocol of Kalmegh (Andrographis paniculata) was established by investigating the factors like combinations of plant growth regulators and explant types (stem, leaf and midrib). To find out the effective medium for callus induction and shoot regeneration, different explants of A. paniculata were cultured on MS media enriched with several concentrations of 6-benzylaminopurine (BA), α-naphthalene acetic acid (NAA) and 2, 4-dichlorophenoxy acetic acid (2,4-D). Stem explant was noticed more responsive than leaf and midrib explant both in callus initiation and shoot regeneration. The ranges of callus initiation from stem, leaf and midrib explants were 26.67 - 100%, 20 - 93.33% and 13.33 - 73.33%, respectively. The calli obtained from midrib explants were not used in shoot initiation because of its poor size. The stem explant exhibited the maximum 73.33% shoot regeneration frequency in a comparison with leaf explants (60%). The maximum callus induction (100%) and shoot regeneration (73.33%) from stem explants were noticed in MS medium strengthened with 0.5 mg/L NAA and 2.0 mg/L BA and half strength MS media complemented with 0.1 mg/L NAA and 3.0 mg/L BA respectively. The highest shoot regeneration from the stem explant may be due to presence of more active parenchymatous cells than that of leaf explant. Half MS medium fortified with 2.0 mg/L IBA considered as best root initiation medium as it resulted in maximum rooting (93.33%). After acclimatization, the plants were transferred to field and found identical to the mother plant.

A pot experiment was conducted at Horticulture Experimental Area, Gomal University, Dera Ismail Khan, Pakistan to investigate the combined effects of NPK and organic manures on growth and yield of carrot, for two consecutive years. The experiment was laid out in CRD with six treatments and four replications. Five different organic manures such as poultry manure (PM), sewage sludge (SS), farmyard manure (FYM), press mud (PrM) and goat manure (GM) were applied in combination with NPK, each at recommended levels for two successive years. A fertilizer check (control) was also included as treatment where no fertilizer and manure were used. The study revealed significant improvements in almost all growth and yield attributes by combined application of NPK and organic manures. Among different combinations, NPK + PM surpassed all other treatments by giving maximum leaves per plant (8.73 and 8.13), leaf length (38.17 and 36.77cm), root length (29.30 and 24.83cm), root diameter (3.10 and 3.27cm), root weight per plant (142.40 and 142.00g), total biomass per plant (169.33 and 166.67g) and root yield (56.67 and 56.83 t/ha), during both the experimental years. Similarly, NPK combination with green manure and sewage sludge also produced better results pertaining to carrot growth and production for two consecutive years. It was also observed during the study that control treatment showed poorest findings and placed at lowest levels.

ABSTRACT. Aim: Examine the relationship between lower limb strength/power and dynamic balance, and whether lower limb strength differences influence balance. Methods: 85 subjects (mean age 20.14, ±0.44) - female (n=63) and male (n=22) 1st-year undergraduate students - participated in this study. Standing long jump and single leg triple hop jump tests were used to determine strength/power, and balance board was used to determine balance. Results: The statistical analysis has revealed no statistically significant correlation between lower limb strength and the average time on balance board after three essays (r = 0.102, df = 83, p = 0.35). As for the relationship between the difference in the scores of the three successive single leg hop jumps and the average time on balance board after three essays, no statistically significant correlation has been found in this case either (r = 0.136, df = 83, p = 0.21). The average score of hop jumps on right leg is (M = 412.54 cm) and the average score of hop jumps on left leg is (M = 403.07 cm); according to the statistical analysis, they differ significantly (t = 2.227, df = 84, p = 0.029). There is a significant difference (t = - 2.625, df = 84, p = 0.01) between the average time on balance board after the first essay (M = 24. 77) and the average time on balance board after the third essay (M = 27.21). Conclusions: In this study, the statistical analysis has revealed no statistically significant correlation between lower limb strength/power and balance. No statistically significant correlation has been found between lower limb strength difference and balance either. Balance board is important in balance development, as shown by the average scores of the three essays (M1 = 24.77, M2 = 26.52, M3 = 27.21).

ABSTRACT. Our topic is the investigation of the influence of parents and coaches of youth soccer children on the children's sports performance, what is the role of coaches in teams of different youth age groups (according to the physiological effects of children), the relationship between coaches and parents, the relationship between coaches and players, the control and development of the most talented players. With our chosen topic, we set myself the goal of examining whether the support and help of parents or coaches has a greater effect on the child's sports performance. We chose this topic because we would like to help during the coaching career in the future, and we also consider it important to develop the skills of young Hungarian football talents, in which parents and coaches have an important and outstanding role. In our article, we would like to reveal what are the outstanding factors that most influence a player's performance on the field, and to what extent coaches and parents contribute to this. We think that it is important for both sides to see their role in the development of football talent. We would also like to examine to what extent parents contribute to the advancement of their child's soccer career, whether they recognize the factors in which they should help their child progress in soccer. After all, in our opinion, without parental support, it will be more difficult for the player to progress, who will also be more balanced emotionally, which also has a significant impact on his sports performance, if the parent monitors and encourages him during his football career. Do soccer coaches consider their relationship with their students important? What is the role of football coaches in the different youth age groups, what is the focus? To what extent does the role and education of parents influence their children's performance, football coaches, how can they cooperate with parents and players? How can football coaches keep under control and develop the most talented child?

Published: August 2023

The study of visual identity elements is a popular area for researchers as they can make a key contribution to the commercial success of a particular brand. Personas/characters, in turn, are one of the most important elements of visual identity, because through them the brand communicates to the target segment those values that define its (i.e. the brand’s) personality. Brad Pitt is an internationally known celebrity: a much discussed global phenomenon. However, investigations into the correlation between Brad Pitt’s professional life and celebrity endorsement represent a gap. This paper is based on the following main objectives: to identify (1) those traits, characteristics that define the actor Brad Pitt and (2) those aspects, values that can be captured in the advertising campaigns included in the analysis.

Authors: BALINT Cristina , DERECICHEI Alexandra
Published: August 2023

The purpose of the paper is to observe and analyze how the dynamics of macroeconomic factors influence the evolution of the Bucharest Stock Exchange (BVB) through the lens of the main stock indices (BET, BET-Plus, BET-FI), but also of the stock market capitalization. The research carried out consists of four stages. First, the monthly values of the macroeconomic factors considered were collected (inflation rate, reference interest rate, unemployment rate, RON-EURO and RON-USD exchange rates, producer price index, gold price, average salary and the Covid-19 number of cases) during the period 2020-2021, as well as the monthly values of the Bucharest Stock Exchange market indices (BET-Plus, BET and BET-FI) and of the stock market capitalization. These data were collected from the websites: www.bvb.ro (Bucharest Stock Exchange), www.bnr.ro (National Bank of Romania), www.innse.ro (National Institute of Statistics) and www.ms.ro (Ministry of Health). Then, the descriptive statistics was used to describe the collected data (mean value, standard deviation, minimum/ maximum value). This step is followed by the use of the Pearson correlation to capture the correlation between each stock market index and the macroeconomic factor included in the analysis. And finally, multiple regression was used to see exactly how the Romanian stock market indices are influenced by any changes of macroeconomic factors.

La sabiduría del rey: valor y representación del concepto en algunos pasajes de obras de Alfonso X
Authors: Disalvo Santiago , Varela Fernanda
Published: August 2023

En diversos pasajes y en el sistema de prólogos de las obras en prosa confeccionadas por voluntad de Alfonso X en su scriptorium, así como en la poesía de las Cantigas de Santa María, puede apreciarse la función del concepto de sapientia en múltiples niveles y con distintos matices: desde el fondo bíblico veterotestamentario hasta los ecos clásicos filosóficos, el vínculo del rex sapiens con el imperator litteratus, e incluso el doble filo de una espada de la sabiduría que puede darse generosa y santamente o bien ser instrumento diabólico. En los celebrados 800 años del nacimiento de Alfonso X (1221-2021), un rey hispánico singular que, a la vez, es cifra y figura de tantos otros “gobernantes sabios” medievales y antiguos, proponemos el recorrido de este tópico en algunas de sus obras, concepto de profundidad a la vez filosófica y religiosa, adherido a la memoria histórica de un monarca auctor y trovador.

Apuntes para historizar la eugenesia desde una perspectiva crítica
Authors: Vallejo Gustavo
Published: August 2023

La eugenesia, “ciencia de la buena raza” al decir de su creador, Francis Galton, ha sido un constructo teórico de vastas implicancias en el mundo occidental que puso en correspondencia la valoración del cuerpo individual y el cuerpo social. Su perspectiva organicista sujeta a la consideración de las consecuencias que la reproducción traía aparejadas atravesó, desde un principio la cultura política, la cultura científica y la religión. Pensar históricamente el impacto de la eugenesia conlleva, entonces, la tarea de detenerse en sus esferas de interacción para reconocer aquello que incomoda a tradicionales caracterizaciones. En este sentido, sacándola del confinamiento en un espacio y tiempo determinado, de una ensimismada forma de entenderla y/o de las lábiles adaptaciones a conveniencias interpretativas, buscaremos aquí plantear algunas ideas para un abordaje crítico de la eugenesia.

Subcutaneous administration of hydromorphone (0.2 mg/kg) provides antinociception in ferrets (Mustela putorius furo)
Authors: Desprez Isabelle , Crookes Andrew , Di Girolamo Nicola , Ambros Barbara
Published: August 2023

OBJECTIVE

To evaluate antinociceptive efficacy of SC administration of hydromorphone hydrochloride and buprenorphine hydrochloride in ferrets (Mustela putorius furo).

ANIMALS

14 healthy adult ferrets (6 neutered males, 8 spayed females).

METHODS

In a randomized, blind, controlled, complete crossover design, all 14 ferrets received a single, SC injection of hydromorphone low dose (0.1 mg/kg), hydromorphone high dose (0.2 mg/kg), buprenorphine low dose (0.02 mg/kg), buprenorphine high dose (0.04 mg/kg), or saline solution (0.2 mL/kg). Sedation and forelimb withdrawal latency from a noxious thermal stimulation were evaluated, and behavior was recorded for a total of 8 hours postinjection.

RESULTS

Compared to saline, administration of hydromorphone at 0.2 mg/kg resulted in an estimated increase of withdrawal latencies of 7.4 seconds (95% CI, 3.2 to 11.6) at 60 minutes, of 6.6 seconds (2.4 to 10.8) at 90 minutes, of 6.0 seconds (1.8 to 10.2) at 120 minutes, of 7.0 seconds (2.9 to 11.1) at 180 minutes, and of 4.5 seconds (0.5 to 8.6) at 240 minutes. These differences were statistically significant. Hydromorphone administered at a lower dose and buprenorphine at either dose did not increase withdrawal latencies compared to saline. Based on the sedation score used in this study, signs of sedation increased over time in a similar fashion with all treatments, including saline. Erratic dysphoric-like behaviors occurred in all groups except for saline.

CLINICAL RELEVANCE

SC administration of hydromorphone at a dose of 0.2 mg/kg provided antinociception from 1 to 4 hours postinjection. Further validation of sedation scores in ferrets is warranted.
Effectiveness and acceptability of Essix and Begg retainers: a prospective study
Authors: Kumar Arun G. , Bansal Anchal
Published: August 2023

Background: Retainers vary in their effectiveness in maintaining teeth in their treated positions and in their acceptability by patients.

Aims: To compare the effectiveness and acceptability of Essix and Begg retainers.

Methods: Two hundred and twenty-four patients were randomly assigned to receive either upper and lower Essix or upper and lower Begg retainers. Subject acceptability was evaluated with seven questions related to chewing and biting, fit, speech, appearance, oral hygiene, comfort and maintenance recorded on a 10-point visual analogue scale. The effectiveness of the retainers to maintain alignment was assessed on study models taken on the day after debonding (T1), after three months retention (T2) and six months retention (T3) with the Peer Assessment Rating (PAR) and Irregularity Index (II). In addition to the upper and lower retainers, all subjects had bonded lower lingual retainers placed at the end of active treatment.

Results: There were small, but statistically significant, deteriorations in the PAR scores in both groups at T2 and T3. The T2-T1 and T3-T1 differences between the groups were statistically significant (Begg > Essix), but the differences did not exceed 2 points. For the Irregularity Index, the T3-T1 difference was statistically significant (Begg > Essix), but clinically insignificant as the difference was only 0.25 points. Subjects preferred the Begg retainer for chewing and biting (p = 0.000), and liked the appearance (p = 0.000) and comfort (p = 0.05) of the Essix retainers. The subjects in both groups reported both retainers had an acceptable fit.

Conclusions: More subjects wearing Essix retainers considered their retainers were comfortable and had an acceptable appearance than subjects wearing Begg retainers, and more subjects with Begg retainers considered that their retainers were acceptable for biting and chewing than the subjects wearing Essix retainers. Both retainers allowed some relapse of teeth post-treatment, but the 6-month differences were small and may not be clinically significant.
Comparison of Australian and American orthodontic clinical approaches towards root resorption
Authors: Lim Elaine , Sameshima Glenn , Petocz Peter , Darendeliler Ali
Published: August 2023

Aims: As part of The Rocky Mountain Travelling Fellowship, a pilot survey was conducted to assess current diagnostic and clinical approaches to the management of orthodontic patients in relation to root resorption.

Methods: Groups comprising Australians (Sydney, New South Wales) and North Americans (Los Angeles, California), in two stages of their orthodontic careers (post-graduate orthodontic students from the University of Sydney and University of Southern California and qualified practising orthodontists) were asked to complete a questionnaire. The questions examined diagnosis and management approaches related to root resorption used in their clinical practice.

Results: Replies demonstrated that there were differences in management depending on operator experience and the country of clinical practice. However, a summarised common approach to orthodontic root resorption comprised (1) the use of an orthopantomogram as a screening diagnostic tool, followed by periapical radiographs for those perceived as ‘higher risk’ patients, particularly individuals with a history of root resorption; (2) a six monthly radiographic review during treatment; (3) the use of light forces and/or rest periods (discontinuous forces) every two to three months; (4) the extraction of deciduous teeth if permanent successors were erupting ectopically and causing damage to adjacent root structures; and (5) the use of fixed retention after treatment.

Conclusion: This project was intended to initiate discussion and form a basis for further investigation into the clinical management of orthodontic root resorption.

Published: August 2023

Aim: The mesiodistal widths of the maxillary and mandibular teeth and anterior and overall tooth size ratios were measured by CBCT and conventional orthodontic plaster methods, compared, and correlation coefficients for both methods determined.

Material and methods: The records of 26 patients (14 males and 12 females) between the ages of 18 and 28 years were randomly selected from the archives of the Oral Diagnosis, Radiology and Orthodontic Departments at the Karadeniz Technical University. The mesiodistal diameters of the maxillary and mandibular permanent teeth from first molar to first molar were measured on the patient’s plaster models and also on CBCT arch renditions. Anterior and overall Bolton ratios were calculated for each method. Comparisons were performed using Pearson’s correlation coefficient (PCC).

Results: The measurements of the mesiodistal widths of most maxillary and mandibular teeth were similar and consistent between the conventional and CBCT methods. PCC values ranged from 0.637 (mandibular right second premolar) to 0.916 (maxillary right canine). PCC values for anterior and overall ratios were 0.756 and 0.781, respectively, indicating that correlations between conventional and CBCT methods were acceptable.

Conclusion: Dental measurements and anterior and overall Bolton ratios calculated on CBCT showed acceptable PCC values indicating that CBCT measurements could be used instead of those obtained from conventional plaster models.

The study showed that the most effective approach to risk management in the energy sector is the use of an integrated risk management system that takes into account all aspects of enterprise activity. The results of the study can be useful for energy companies that deal with risk management. They can be used to improve risk management strategies and reduce the possibility of negative consequences. In addition, this research can be used for educational purposes for students and professors who study risk management and the energy sector. The next steps of the research may include expanding the scope of the study to other areas and developing more detailed risk management models.

Undergraduate students are a high-stress population with a high prevalence of psychopathology. Further, students from historically marginalized racial groups face additional stressors and challenges. The aim of this study was to investigate the impact of identifying with a historically marginalized racial group on the relationship between stress and mental health outcomes. We used archival data, in which 528 college students were originally recruited to complete surveys on college-related stress and symptoms of psychopathology. Analyses of variance were employed to study differences in rates between a historically marginalized racial group and a historically advantaged racial group. Regression analyses were employed to study the moderating effect of identity group on the relationship between stress and mental health outcomes. The historically marginalized racial group was more likely to report performance stress (p = .008) and the historically advantaged racial group was more likely to report internalized symptoms of psychopathology including anxiety (p = .007) and depression (p = .02). Furthermore, group marginalization moderated the relationship between total stress (p < .001), financial stress (p < .001), and performance stress (p < .001) with symptoms of internalized psychopathology. Our findings may be explained by a difference in resilience, interpretation of stress, or limitations to survey methods. Recommendations for researchers and clinicians are offered.

Given the prevalence of public use of devices to send private messages, these messages are prone to be snooped upon by others. Advances in technology have raised privacy concerns, however, little is known about what is typically sought after and the characteristics of those more likely to snoop. People are socially curious and drawn to gossip, suggesting that personal information that is dramatic or salacious may be more tempting for individuals to access when given the opportunity. In addition, certain personality characteristics relate to negative behaviors online, however, it is unknown what individual differences are related to snooping behaviors. Therefore, we designed novel studies in which participants watched videos where pop-up text message notifications, supposedly for the researcher, appeared. Using eye-tracking, we assessed what factors led to fixation on these fake texts. Results showed participants were more likely to fixate on gossipy texts during passive videos (Z = 303.50, p = .01, d = 0.48), and higher conscientiousness was related to lower snooping, r(26) = –.50, p = .01, 95% CI [–.78, –.22]. Further, individual fear of missing out predicted higher fixation only of gossipy texts, r(22) = .55, p = .01, 95% CI [.15, .79], but independent of text type, greater fixation to texts led to divided attention and poorer memory of video content, r(46) = –.50, p < .001, 95% CI [–.73, –.33]. Together, data suggest that there are costs to private information being made public, both to the individual whose information is on display and the snooper.
Risk Perceptions, Health Attitudes, and Individual Differences During the COVID-19 Pandemic

Published: August 2023

Throughout the last several years, there have been varying responses to the COVID-19 pandemic. This study (N = 211) explored individual differences (i.e., health anxiety, education, and age) as correlates of COVID-19 risk perceptions, the relationship of these risk perceptions with attitudes toward cautionary behaviors, such as masking and vaccination, and examined how political beliefs—specifically liberalism—influenced those relationships to better understand the varying responses to the pandemic and how certain demographic groups differ in their COVID-19 risk perceptions. COVID-19 risk perception had significant positive correlations with health anxiety (r = .37, p < .001), education (r = .21, p = .003), attitude toward masking (r = .40, p < .001), attitude toward the COVID-19 vaccination (r = .27, p < .001), and liberalism (r = .36, p < .001), but not age. Liberalism moderated the relationship between COVID-19 risk perceptions and attitude toward masking (p = .02, f2 = .02) and the relationship between COVID-19 risk perceptions and attitude toward vaccination (p = .02, f2 = .02). Lastly, regarding demographic group differences, we found that COVID-19 risk perceptions differed by age (p = .04, d = 0.24) and gender (p < .001, d = 0.50), but not by education. Results support previous research and provide new insights regarding perceived COVID-19 risk and attitudes toward cautionary behaviors, stressing the impact of individual differences on responses to public health emergencies such as COVID-19. Implications and suggestions for future research are discussed.

Subject. The article explores the impact of various factors on assessment of the grain industry development and formation of its production potential in the future, using the case of agricultural agro-district of the Nizhny Novgorod Oblast.
Objectives. The purpose is to assess the resource potential of the grain industry development based on the use of factor and correlation analyses of the main components affecting the agricultural production of grain crops.
Methods. The study employs general scientific (analysis and synthesis, formalization, analogy and comparison) and special (statistical, correlation, factor analysis) research methods.
Results. We analyzed the production of grain crops in the context of agro-climatic zones of the Nizhny Novgorod Oblast as part of municipalities of the region, performed the factorial and correlation analysis of the influence of individual parameters and conditions on grain production. The paper graphically presents the distribution of areas of the agricultural agro–district under study by two factors, i.e. the production potential of the organization and the personnel and resources to increase the volume of production in the future.
Conclusions. The considered methods of analyzing factors and conditions of grain production determined a close relationship between the system-forming resources in agriculture, which are land and labor. The study defines their structural contribution to the formation of reserves for improving the efficiency of the grain industry and enhancing its potential in the future.

Se analiza la procedencia del recurso extraordinario de casación partiendo de la concepción del Estado social de derecho; para ello se resalta la evolución legislativa y jurisprudencial de este recurso en los asuntos del trabajo y la seguridad social. En el escenario de la protección y tutela efectiva de los derechos y las garantías constitucionales, la casación debe estar enmarcada en una justicia formal, material y eficaz, y para ello se debe flexibilizar su técnica, en especial cuando se vean involucrados los derechos fundamentales al trabajo, al debido proceso y a la seguridad social, entre otros. Se enfatiza en el acoso laboral como una problemática que aqueja a los trabajadores y en la posible procedencia de la casación para tratarla en aras de la protección constitucional de los derechos del trabajador, teniendo como eje principal la dignidad humana y partiendo del análisis de la jurisprudencia al respecto en nuestro país. Se propone que el requisito para el otorgamiento del recurso extraordinario de casación no sea un interés económico para recurrir, sino la tutela efectiva de los derechos humanos sociales. De manera concreta, se propende por una alternativa jurídica para garantizar el acceso a la administración de justicia en casos de acoso laboral y, en este sentido, se plantea la sede del recurso extraordinario de casación como un espacio que posibilite la protección real de los derechos fundamentales de los trabajadores que pudieron haber padecido acoso laboral.
