Keynes’s Message, Method and Language in the Works of Fausto Vicarelli

/0 Comments/in /by

This essay examines Keynes’s theoretical message, method and language, and traces their presence in the works of Fausto Vicarelli and in his intellectual legacy. Since the 1930s, following Keynes, the explanatory core of the business cycle has been located in the instability of the saving–investment relationship. Keynes regarded economics as a branch of logic rather than of mathematics — a way of thinking, not a pseudo-natural science. He did not write in the esoteric jargon of mathematicians addressed to a few colleagues; he used instead the language of those whose understanding and support were necessary for policy intervention. Following Keynes, Vicarelli stressed that economics is not an isolated body of knowledge but one inseparable from philosophy, psychology, history and politics. For him, economics was an important scientific discipline, yet unable, by itself, to capture the essence of human social behaviour.

Effects of Different Levels of DAP on Agronomical Characteristics and Yield of Mung bean

/in /by

Phosphorus deficiency is one of the main factors restricting mung bean (Vigna radiata L.) production in many parts of the world, including Afghanistan. Therefore, a field experiment was carried out in the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University, to determine the influence of different diammonium phosphate (DAP) fertilizer levels on mung bean growth and yield. The experiment was arranged in a randomized complete block design (RCBD) with three replications, consisting of four DAP rates: 0, 30, 60, and 90 kg ha⁻¹. The collected growth and yield data were analyzed using analysis of variance (ANOVA), and mean comparisons were performed using the Least Significant Difference (LSD) test at a 5% probability level. The application of DAP fertilizer significantly improved plant height, shoot dry matter, number of branches, pods per plant, pod length, seeds per pod, and 100-seed weight. However, leaf number, grain weight per square meter, seed yield, and harvest index did not show significant differences among fertilizer treatments, although higher values were generally observed compared with the control treatment. The maximum seed yield (870.83 kg ha⁻¹) was obtained from the application of 60 kg DAP ha⁻¹, while the highest performance for most growth and yield-related traits was recorded under 90 kg DAP ha⁻¹. The findings suggest that DAP fertilizer application enhances mung bean growth and yield performance under the environmental conditions of Kabul. Among the tested fertilizer levels, 60 kg DAP ha⁻¹ was found to be the most effective rate for achieving higher grain yield.

Impact of Screen Time [PHONES, T.V., SOCIAL MEDIA] on Snacking Frequency in Children [5–14 Years] of Meerut District

/in /by

Children today spend a good part of their day in front of some screen or another, and parents often wonder how much of an effect this really has on the way their kids eat. That question is what this study set out to answer. Fifty parents of children aged 5–14 years in Meerut district, Uttar Pradesh, were interviewed using a structured questionnaire as part of a cross-sectional descriptive study, and their answers were analysed using simple frequency and percentage calculations, then laid out in tables and graphs. What came out of the data was fairly consistent: television and mobile use both hovered around 1–2 hours a day for most children (36% and 32% respectively), and screen use was heaviest in the afternoon (56%) rather than morning or night. YouTube Shorts turned out to be the clear favourite among children (42%). Eating in front of a screen was the norm rather than the exception 34% of children always ate this way, and only 8% never did. Interestingly, when parents were asked why their children snack during screen time, taste (26%), hunger (24%) and habit (24%) came up far more often than advertisements (8%), which goes against the common assumption that ads are the main culprit. Nearly half the parents (46%) also mentioned that their child gets irritated if the screen is taken away mid-meal. Taken together, these findings suggest that screen time and snacking have become tightly woven into daily routine for many children in Meerut, and that the fix probably lies less in banning screens outright and more in building steadier mealtime habits and a bit more mindfulness around eating.

Effect of Foliar Application of Gibberellic Acid at Different Concentrations on Growth, Yield and Quality of Soybean (Glycine max L) under Semi-Arid of Kabul conditions

/in /by

Soybean (Glycine max L.) is one of the most important legume crops cultivated worldwide for its high-quality protein and oil content. Using the Plant Growth Regulators (PGRs), particularly gibberellic acid (GA₃) for foliar application, is considered to have great potential in enhancing the yield of soybeans. This study was conducted to investigate the effect of foliar-applied GA₃ on the growth and yield of soybean under the semi-arid condition prevailing in the Kabul University research farm during the 2025 growing season (May-September). Different concentrations of GA₃, such as 0, 50, 100, and 150 ppm, were used at the V6, pre-flowering, and pod-setting stages. The results showed that GA₃ application significantly influenced the growth performance, yield attributes and, seed quality. The plants treated with 150 ppm produced the tallest plants (64.14 cm). The maximum branch number (6.1) and leaf area (42.4 cm²) were recorded in plants treated with 100 ppm GA₃, and there was no significant difference between 100 and 150 ppm. The maximum number of pods per plant (60.35), seed yield (2967.3 kg ha), harvest index (43.4%), 100-seed weight (15.17 g), and seeds per pod (3.07) were noted in plants treated with 150 ppm. However, for all these parameters, there was no significant difference between 100 ppm and 150 ppm treatments. Protein and oil contents were highest in the 100-ppm treatment (38.03 and 19 %).

Effects of Varying Levels of Poultry Manure on Growth and Yield of Canola (Brassica napus L.) under Kabul Agro-climatic Conditions

/in /by

Canola (Brassica napus L.) is one of the key oilseed crops worldwide, serving as a vital source of edible oil, livestock feed, and biofuel. In Afghanistan, canola production faces significant challenges due to declining soil fertility and over-reliance on expensive chemical fertilizers. Poultry manure, as a low cost and nutrient-rich organic fertilizer, offers a sustainable alternative for improving crop productivity. However, limited scientific information is available regarding the optimal poultry manure application rate for canola under Kabul’s agro-climatic conditions. Therefore, an experimental research was conducted at Kabul University Agricultural Research Farm during the 2025 cropping season using Randomized Complete Block Design (RCBD) with three replications and four treatments. The study aimed to evaluate Effects of Different Levels of Poultry manure on Growth, Yield, and Yield Components of Canola. The findings of the study revealed that the application of poultry manure significantly influenced on growth, yield and yield components of canola. Overall, the application of 8-ton poultry manure ha-1 had better performance than control. The maximum plant height (117.45 cm), number of branches plant-1 (5.65), number of leaves plant-1 (39.77), number of siliques plant-1 (184.61), silique length (6.01 cm), number of seeds silique-1 (18.39), thousand seed weight (3.40 g), seed yield (2.74 t ha⁻¹), biological yield (9.87 t ha⁻¹), and harvest index (27.76%) were all recorded in T4. The lowest values for all parameters were observed in the control treatment (T1). It is recommended that use 8 tons of poultry manure ha-1 in order to realize optimal seed yield and biological yield of the crop.

Risk Factors for Needle Stick Injuries (NSIs) Among Medical Solid Waste Handlers at Hospital X, Lampung Province, Indonesia

/in /by

Background: Needle Stick Injury (NSI) is an occupational accident that poses a risk of transmitting infectious diseases to personnel responsible for managing solid medical waste. The occurrence of NSI is presumed to be influenced by compliance with the use of Personal Protective Equipment (PPE), the implementation of safety boxes, adherence to Standard Operating Procedures (SOPs), and Occupational Health and Safety (OHS) training.

Objective: To analyze the association between compliance with PPE use, safety box implementation, adherence to SOPs, and OHS training with the occurrence of NSI among solid medical waste management personnel at Hospital X, Lampung Province.

Methods: A quantitative study with a case–control design was conducted from May to July 2026 involving 45 respondents, consisting of 9 cases and 36 controls. Data were collected through questionnaires, observations, and secondary data, and were analyzed using the Chi-square test with a 95% confidence level.

Results: A total of 20.0% of respondents had experienced NSI. No significant associations were found between PPE compliance (p = 0.171), safety box implementation (p = 0.086), or adherence to SOPs (p = 0.118) and the occurrence of NSI. However, OHS training was significantly associated with NSI (p = 0.048). Respondents who had inadequate OHS training were six times more likely to experience NSI than those with adequate training (OR = 6.000; 95% CI = 1.238–29.069).

Conclusion: OHS training was identified as a factor significantly associated with the occurrence of NSI, whereas compliance with PPE use, safety box implementation, and adherence to SOPs showed no significant associations. Strengthening structured and comprehensive OHS training programs is essential to reduce the risk of Needle Stick Injury.
