Do ride-hailing congestion fees in NYC work?

What is the impact of congestion policies targeting ride-hailing systems? This work empirically evaluates NYC’s congestion surcharge policy, particularly in light of the city’s forthcoming implementation of congestion pricing. Using a Difference-in-Differences (DiD) framework, our analysis reveals a statistically significant reduction of approximately 11% in overall ride-hailing travel volume following the implementation of the policy. In particular, Lyft experienced a 17% reduction in travel demand while Uber and yellow-cabs experienced reductions of about 9% and 8% respectively. We further elucidate two key mechanisms — travel distance and subway station availability — to explain this reduction. The surcharge policy has a more pronounced impact on shorter trips (with the most significant decline observed in trips less than one mile), and on ride-hailing trips originating from areas with at least one substitute (such as subway or Citi Bike). Furthermore,the policy’s effect seems more pronounced in lower-income areas of the city and seems to reduce street-hailing industry revenues by 8%. However, despite these reductions, the policy does not result in a corresponding decrease in traffic congestion. Thus, it seems that the policy results in a net welfare loss for the city, at least in the shorter term. Our findings provide insights for understanding the dynamics of congestion policies focused on the ride-hailing industry, especially as New York City prepares to introduce congestion pricing.

The (Un)Attractiveness of Dark Triad Personalities: Assessing Fictitious Characters for Short‐ and Long‐Term Relationships

ABSTRACTObjectiveThe current study assessed how individuals evaluate potential romantic partners who display either low, medium, or high levels of DT traits for short‐term (STR) and long‐term (LTR) relationships.MethodsNine fictitious persons in the form of vignettes (description of behavior and facial image) were presented to every participant. The sex of the fictitious persons was determined by sexual orientation of each participant, while the displayed faces were selected from an existing image bank and matched for physical attractiveness. Study 1 (n = 475) used a fixed composition for face and trait description, while the composition for Study 2 (n = 794) was randomized. Mixed‐effects modeling was implemented for both studies.ResultsStudy 1 demonstrated people with a male preference (mostly women) perceived medium levels of the three traits as the most attractive STR. For Study 2, both men and women found the low levels the most attractive for both STRs and LTRs.ConclusionsFindings from Study 1 were mostly consistent across previous DT attractiveness literature, while findings from Study 2 contradicted them. This could suggest that the concept of DT is not as attractive even for STRs unless it is accompanied by physical attractiveness.

The Repo Market and Conflict Inflation

This article seeks to connect today's inflation with one of the least studied and understood creations of the Federal Reserve - the repurchase (repo) market. Despite decades of existence, it is only in the last few years that the repo market has ceased to function smoothly, experiencing first a moment of crisis followed by one of great profitability. When functioning properly, the repo market went virtually unnoticed. Now that it is not, the market has gained the attention of mainstream economics as well as policy makers. However, conventional academic analysis is limited and cannot fully capture the effects that the repo market has had on the overall economy. In this article, we argue that the causes of the pandemic inflation and its public policy response can be understood as the culmination of the longer term currents of globalized financialization and central bank independence. To sharpen our focus on the shorter term, we construct upon the heterodox position of conflict inflation, and argue that the repo market and its principle actors should be considered within the discussion.

“Caught in the middle”- emergency doctors and nurses’ experiences of ethical dilemmas in end of life care: A qualitative study

ObjectiveThe integration of end of life care into emergency work is gaining momentum, especially in Australia. Emergency doctors and nurses are increasingly required to make decisions regarding the provision of end of life care. The importance of end of life care for patients and their families in the emergency department is well documented, but ethical dilemmas that arise in end of life care provision are not widely researched. MethodsA qualitative interpretative design and phenomenological approach were used to create an understanding and meaning about ethical dilemmas faced by emergency nurses and doctors in end of life care. Sixteen doctors and nurses were purposively recruited through professional organisations. Data were collected using semi-structured in-depth interviews. Interviews were audio-taped, transcribed verbatim, and thematically analysed using a qualitative seven stage thematic analysis. ResultsThe overarching constitutive pattern ‘decision making processes’ was conceptualised within the two identified major themes including: 1) Short-term (ST) versus Long-term (LT) ethical dilemmas and; 2) Individual versus community ethical dilemmas. These themes were uncovered using the phenomenological hermeneutic concepts of epoche (openness) to construct meaning and understanding for participants. ConclusionsIn this study, the frequent experiences of ethical dilemmas by emergency doctors and nurses demonstrated that end of life care in the emergency department was challenging. The stated experiences were related to barriers that contributed to the complexities reported in making ethical decisions at the end of life. Therefore, an understanding of ethical principles is needed to navigate care for patients and their families for the best possible outcomes.

Youth Engagement in Transforming the Food System to Address Malnutrition in the Philippines

Unless the Philippine food system is made more resilient, the aspirations of AmBisyon Natin 2040 will remain elusive, hindering the country’s ability to achieve inclusive growth, eradicate poverty, and ensure the well-being of all Filipinos. Focused on the youth, this paper brings together three related issues: (1) how can the youth be encouraged to devote their careers to agriculture? (2) How do poor quality diets compromise the cognitive abilities of young people? and (3) How can nutrition concerns be incorporated into agricultural policies? Early exposure to agricultural concepts can inspire young people to pursue careers in agriculture, ensuring a steady influx of leaders and professionals equipped to tackle the challenges within the food system. This approach not only secures the future of the agriculture sector but also promotes innovation and resilience in food production and distribution. One in two preschoolers in the lowest wealth quintile in the Philippines are stunted, while only one in eight in the highest wealth quintile are stunted. Children who are stunted are not reaching the full potential of their cognitive development. The dietary quality of mothers before pregnancy, during pregnancy, and during breastfeeding improves markedly with income and so is associated with the better heights of their children. In the long term, agricultural productivity must be improved with a particular focus on increasing the incomes of the poor. Increasing household income is the most sustainable way to improve dietary quality. In the shorter term, there are two broad strategies to link Philippine agriculture to nutrition by adding more minerals and vitamins to the food supply: (1) by increasing the density of minerals and vitamins in food staples, a strategy referred to as “biofortification,” and (2) by lowering the prices of nutritious nonstaple food such as vegetables, fruits, pulses, fish, and meat through improved productivity that results in rapid supply increases.

Decompensated MASH-Cirrhosis Model by Acute and Toxic Effects of Phenobarbital.

Metabolic dysfunction-associated Steatohepatitis (MASH), is a prominent cause for liver cirrhosis. MASH-cirrhosis is responsible for liver complications and there is no specific treatment. To develop new therapeutic approaches, animal models are needed. The aim of this study was to develop a fast animal model of MASH-cirrhosis in rats reflecting the human disease. Carbon tetrachloride (CCl4) injections in combination with a high-fat Western diet (WD) were used to induce MASH-cirrhosis. To accelerate liver injury, animals received phenobarbital (PB) in their drinking water using two different regimens. Rats developed advanced MASH-cirrhosis characterized by portal hypertension, blood biochemistry, hepatic ballooning, steatosis, inflammation and fibrosis. Importantly, rats receiving low-dose PB for the long term (LT) showed ascites after 6 weeks, whereas rats with high-dose short-term (ST) PB developed ascites after 8 weeks. ST- and LT-treated rats showed increased portal pressure (PP) and decreased mean arterial pressure (MAP). Of note, hepatocyte ballooning was only observed in the LT group. The LT administration of low-dose PB with CCl4 intoxication and WD represents a fast and reproducible rat model mimicking decompensated MASH-cirrhosis in humans. Thus, CCl4 + WD with LT low-dose phenobarbital treatment might be the preferred rat animal model for drug development in MASH-cirrhosis.

Comment on Dijkstra et al. A False-Negative Newborn Screen for Tyrosinemia Type 1-Need for Re-Evaluation of Newborn Screening with Succinylacetone. Int. J. Neonatal Screen. 2023, 9, 66.

The assessment of newborn screening (NBS) algorithms' performance to ensure quality improvements is a continuous process: false-positive referrals can enable optimisations in the shorter term, but false-negative referrals are often only discovered many years after the screening has taken place [...].

EphrinB2 in excitatory neurons and astrocytes in the basolateral amygdala controls long-term fear memory formation

EphrinB2 regulates synaptic transmission and morphology however its role in memory formation is unknown. Here we show that deleting ephrinB2 from excitatory neurons in the basolateral amygdala (BLA) of male mice impairs long-term (LTM), but not short-term (STM), fear memory formation. Deleting ephrinB2 from astrocytes in the BLA impairs fear LTM but not STM. Removing ephrinB2 from astrocytes in the BLA reduces the level of the excitatory amino acid transporter 1 (EAAT1) in these cells. Inhibiting EAAT1 activity in the BLA during fear conditioning, by its specific inhibitor UCPH-101, impairs fear LTM showing that EAAT1 in the BLA is needed for fear LTM formation. The administration of ephrinB2 into the BLA during fear conditioning training enhances fear LTM. Moreover, ephrinB2 increases the ability of fear conditioning to activate cells in the BLA as detected by c-Fos labeling. EphrinB2 therefore determines the threshold for fear memory formation. In contrast to mature neurons, we show that ephrinB2 in neural stem cells (NSCs) is not needed for fear LTM. Our study shows that ephrinB2 in the BLA determines the strength of long-term memory consolidation.

The use of a modern robotic system for the treatment of severe knee deformities.

Robotic-assisted total knee arthroplasty (TKA) have shown promising results in recent years with improved clinical outcomes using standard primary implants. The purpose of this study was to assess the experience of a single center in correcting severe coronal deformities with the use of a robotic-assisted TKA system and an increased constrained implant. Between July 2020 and December 2022, 30 knees in 28 patients with a major deformity and an associated ligament laxity requiring an increased constrained implant treated using an imageless robotic-assisted TKA were prospectively enrolled. Patients included in the study showed a minimum 15 degrees varus or 10 degrees valgus deviation. 20 cases were varus knees and 10 cases were valgus knees. Postoperative neutral alignment was defined as 0∘± 2.5∘. A CCK implant was used in 20 cases while a Constrained Posterior Stabilized implant was used in 10 cases. A neutral alignment was achieved in all patients. At a minimum 6 months follow up (f-u 6-30 months) clinical outcomes including ROM, KSS, HSS, OKS and WOMAC showed significant improvement and no major complications were registered. The robotic system showed the achievement of a mechanical alignment with reliable radiographic outcomes and clinical results in the treatment of major deformities of the lower limb with the use of higher constrained implants at short term follow up. Further follow up and studies are necessary to confirm and verify these promising outcomes.

The comparison effect on earthworms between conventional and biodegradable microplastics

Many studies have reported the toxic effects of microplastics (MPs) on organisms, especially on how conventional plastics affect organisms after short-term exposure. The effects of biodegradable plastics on organisms are, however, largely unexplored, especially concerning their impact after long-term exposure. We perform a series of experiments to examine the effects of conventional (polyethylene (PE)) and biodegradable (polylactic acid (PLA)) microplastics on earthworms at three concentrations (0.5 %, 2 %, and 5 % (w/w)) and particle sizes (149, 28, and 13 μm) over short- (14 d) and long-term (28 d) periods of exposure. Negative effects on earthworms are more pronounced following exposure to PE than PLA, particularly over the shorter term. After longer-term exposure, earthworms may adapt to PE and PLA environments. A close relationship exists between the effects of MPs on earthworms and activities of superoxide dismutase, catalase, and malondialdehyde enzymes, which we use to evaluate the degree of antioxidant damage. We report both PE and PLA to negatively affect earthworms, but for the effects of PLA to be less severe after longer-term exposure. Further investigation is required to more fully assess the potential negative effects of PLA use on soil organisms in agriculture.

Financial hardship after COVID-19 infection among US Veterans: a national prospective cohort study

BackgroundResearch suggests an association between COVID-19 infection and certain financial hardships in the shorter term and among single-state and privately insured samples. Whether COVID-19 is associated with financial hardship in the longer-term or among socially vulnerable populations is unknown. Therefore, we examined whether COVID-19 was associated with a range of financial hardships 18 months after initial infection among a national cohort of Veterans enrolled in the Veterans Health Administration (VHA)—the largest national integrated health system in the US. We additionally explored the association between Veteran characteristics and financial hardship during the pandemic, irrespective of COVID-19.MethodsWe conducted a prospective, telephone-based survey. Out of 600 Veterans with COVID-19 from October 2020 through April 2021 who were invited to participate, 194 Veterans with COVID-19 and 194 matched comparators without a history of infection participated. Financial hardship outcomes included overall health-related financial strain, two behavioral financial hardships (e.g., taking less medication than prescribed due to cost), and seven material financial hardships (e.g., using up most or all savings). Weighted generalized estimating equations were used to estimate risk ratios (RR) and 95% confidence intervals (CI) of financial hardship by COVID-19 status, and to assess the relationship between infection and Veteran age, VHA copay status, and comorbidity score, irrespective of COVID-19 status.ResultsAmong 388 respondents, 67% reported at least one type of financial hardship since March 2020, with 21% reporting behavioral hardships and 64% material hardships; 8% reported severe-to-extreme health-related financial strain. Compared with uninfected matched comparators, Veterans with a history of COVID-19 had greater risks of severe-to-extreme health-related financial strain (RR: 4.0, CI: 1.4–11.2), taking less medication due to cost (RR: 2.9, 95% CI: 1.0–8.6), and having a loved one take time off work to care for them (RR: 1.9, CI: 1.1–3.6). Irrespective of COVID-19 status, Veterans aged < 65 years had a greater risk of most financial hardships compared with Veterans aged ≥ 65 years.ConclusionsHealth-related financial hardships such as taking less medication due to cost and severe-to-extreme health-related financial strain were more common among Veterans with a history of COVID-19 than among matched comparators. Strategies are needed to address health-related financial hardship after COVID-19.Trial registrationNCT05394025, registered 05–27-2022.

Clonal analysis of fetal hematopoietic stem/progenitor cells reveals how post-transplantation capabilities are distributed

It has been proposed that adult hematopoiesis is sustained by multipotent progenitors (MPPs) specified during embryogenesis. Adult-like hematopoietic stem cell (HSC) and MPP immunophenotypes are present in the fetus, but knowledge of their functional capacity is incomplete. We found that fetal MPP populations were functionally similar to adult cells, albeit with some differences in lymphoid output. Clonal assessment revealed that lineage biases arose from differences in patterns of single-/bi-lineage differentiation. Long-term (LT)- and short-term (ST)-HSC populations were distinguished from MPPs according to capacity for clonal multilineage differentiation. We discovered that a large cohort of long-term repopulating units (LT-RUs) resides within the ST-HSC population; a significant portion of these were labeled using Flt3-cre. This finding has two implications: (1) use of the CD150+ LT-HSC immunophenotype alone will significantly underestimate the size and diversity of the LT-RU pool and (2) LT-RUs in the ST-HSC population have the attributes required to persist into adulthood.

Safety and efficacy of the mAXIS stapes prosthesis

PurposeOtosclerosis leads to a fixed stapes footplate and thus to hearing loss. The predominant treatment method is surgery, with various types of stapes prostheses available. The aim of this study was to investigate the safety and efficacy of the new mAXIS Stapes Prosthesis.Methods34 cases of otosclerosis were implanted with the new mAXIS Stapes Prosthesis. Comprehensive clinical assessments, including pre- and postoperative pure tone audiometry was performed at short-term (ST) follow-up at 25 (± 15) days and mid-term (MT) follow-up at 181 (± 107) days. The pure tone average of 0.5, 1, 2 and 3 kHz (PTA4) was calculated.ResultsIn all cases, the application of the prosthesis was successful and straightforward. The postoperative PTA4 air-bone gap was 10.7 ± 5.2 dB at ST follow-up (n = 34) and 8.3 ± 4.1 dB at MT follow-up (n = 18). In 61% of cases, the ABG-closure was within 10 dB and in 100% of cases within 20 dB at MT follow-up.ConclusionFindings of this study support that the mAXIS Stapes Prosthesis is safe for implantation and shows promising audiological outcome. Future investigations will contribute its long-term efficacy and safety profile.

The Smart Grid Challenge is Social Rather than Technological

Background: Smart grids have expanded over the last decade, with large-scale smart meter deployments in several regions of the world. Objective: The goal of this perspective is to discuss the social challenges faced by smart grids. While numerous scholarly works have thoroughly examined smart grids from a technical perspective, a noticeable shift has occurred in recent years towards conducting research about the interaction between technology and customers that shows some issues to future deployments. Methods: This study is a review of recent literature on smart grids focused on studies related to the social acceptance of these networks, which has been published in the last five years. Results: The review of studies shows that discussion about smart grids has been traditionally focused on technology, paying no attention to social issues. Conclusion: It is essential to understand the motivations behind public perceptions of smart grids in order to enhance and extend awareness campaigns in the short and medium term, as without social support, the expectations placed on smart grids may be severely limited.

Open Access ‘Unaccomplished’ – Reforming Copyright or Reconceptualizing Science? Access to Scholarly Publications under a (Reinterpreted) Right to Science

ABSTRACT This article identifies the impediments to science created by copyright and suggests ways to overcome these. It focuses on scholarly publishing—primarily of digital content—and queries whether commercial scholarly publishers continue to add value to research in the digital era. The deficits of copyright law, and potential solutions thereto, are assessed in light of the right of everyone ‘to enjoy the benefits of scientific progress and its applications’ (‘REBSPA’ or ‘right to science’), as protected in Article 15(1)(b) of the International Covenant on Economic, Social and Cultural Rights of 1966. I find that, while, in the shorter term, existing copyright law needs to undergo certain reforms (which would all be supported by the REBSPA) to accommodate the needs of science, in the longer term, the right to science requires something else—much more, in fact. Firstly, there needs to be a move towards another science, a science reconceptualized so as not to be primarily driven by instrumental and profit motives. Secondly, following from that, science would need to be genuinely open. Among other things, this requires the creation of a true scholarly knowledge commons, necessitating far-reaching changes in the way copyright applies, or potentially its abolition, in science. Thirdly, the envisaged scholarly knowledge commons would have to be globally inclusive in scope—which is to be achieved by recognizing and respecting the mostly ignored international dimension of the right to science. This article questions the traditional role of the commercial scholarly publishers and argues for a paradigm shift in the sphere of copyright and science. Identifying flaws and gaps in the current official interpretations of the REBSPA, the right to science is reinterpreted in various respects here. In making my case, I rely on the notion of a ‘right to research’ under the REBSPA and am aided by the deconstructive concept of ‘adequacy for science’.

Results of biochemical and histological studies after restoration of bone defects using cellular technologies in dental patients

Objective of the research was to find out the effectiveness of the use of osteoplastic materials based on the multipotent mesenchymal stromal cells of the adipose tissue during surgical treatment for restoration of bone defects in dental patients. The clinical material included examination of 79 patients who underwent replacement of bone defects of the alveolar processes and/or an alveolar part of the appropriate jaw by means of different osteoplastic materials and their combinations or without their application (the control group). Acid phosphatase activity in the oral fluid of patients was determined by means of the unified “end point” method. Alkaline phosphatase activity in the oral fluid was determined using a set of reagents produced by the company “Filisit-Diagnostika” (Ukraine). Oral fluid mineralization index (MI) of patients was calculated according to the ratio of enzymatic activity of alkaline phosphatase (ALP) to acid phosphatase (AP) according to the formula: MI=ALP/AP. Histological material was taken at the stage of installation of a dental implant. It was established that the use of a composition based on multipotent mesenchymal stromal cells of adipose tissue, platelet-enriched blood plasma and bone tissue substitute containing hydroxyapatite contributes to the improvement of regenerative processes in the bone tissue of the jaws, which is confirmed by a 28.68% decrease in acid phosphatase activity, an increase by 25, 97% of alkaline phosphatase activity in the oral fluid of group B patients and, accordingly, a 77.08% increase in the ratio of alkaline to acid phosphatase. According to the results of histological studies and phase-contrast microscopy, after 6-8 months of observation, in patients of group B, the areas of jaw defects were filled with newly formed bone tissue, identical to native bone, and the resulting trepanobioptas had the structure of cancellous bone with osteoblastic elements forming a chain around osteoid tissue. Having analyzed the results of biochemical and histological studies it was established that application of an osteoplastic composition based on the multipotent mesenchymal stromal cells of the adipose tissue, bone tissue substitute with hydroxyapatite and platelet-rich plasma allows restoration of bone defects of the alveolar processes and an alveolar part of the appropriate jaw in shorter terms. The method is an optimal alternative to traditional osteoplastic materials to be used in modern dental practice and dental implantation.

Astrometry of directly imaged exoplanets with optical interferometry

Optical interferometry has always been seen as a promising but difficult technique for astronomy. Until the year 2018, it was excrucially limited in sensitivity to magnitudes below 10. However, thanks to the advent of the GRAVITY instrument, fringe tracking and dual field interferometry made it possible to observe very faint target. This paper presents the different techniques used by optical interferometry to perform astrometry. It shows why dual field interferometry has become the key technique for faint companions. Taking the exemple of the HD 95086 b exoplanet, we show how dual field interferomtry can detect an exoplanet as faint as magnitude 19.5, and how its astrometry was extracted. Use this example this paper explains how and why an astrometric accuracy of 10μas is possible, and describes the remaining biases that can hinder this measurement. Last, we conclude by presenting the orbital trajectory of 10 exoplanets in 4 systems, and conclude with the short and longer term perspectives of the technique.

A comprehensive stochastic-based adaptive robust model for transmission expansion planning

To address various uncertainties appearing in the transmission expansion planning (TEP) problem, appropriate tools such as stochastic programming (SP) or robust optimization (RO) are required. On the other hand, both long-term (LT) and short-term (ST) uncertainties must be well captured to acquire the most reliable and robust solution. The current works model the LT uncertainty by RO and the ST uncertainty by SP, forming a two-stage adaptive robust optimization problem. In contrast, this paper presents a novel approach in which the SP and RO are simultaneously utilized to cope with each type of uncertainty, i.e., LT and ST uncertainty. Unlike the current methods with bilinear terms appearing in the subproblems, the trilinear terms appear in the objective function of the proposed approach, which are linearized accordingly. In addition, we propose a mixed-integer bilinear programming (MIBP) model to specify the rectangles used as uncertainty sets, which is further solved using Konno's algorithm. A standard column-and-constraint (CCG) generation solves the established tri-level structure. Two case studies are used to implement the formulation developed in this work. Results signify the effectiveness of the proposed method.

Obstetric outcomes of patients with inflammatory bowel disease.

Inflammatory bowel diseases (IBD) are frequently diagnosed between the ages of 20 and 40, i.e. the most fertile period for women. The potential impact of IBD on pregnancy is therefore a frequent issue. To determine the impact of disease activity during pregnancy on the obstetric prognosis of women with IBD. Gastroenterological and obstetric data were collected for patients for all consecutive patients with IBD and pregnancy followed up at Amiens University Hospital (Amiens, France) between 2007 and 2021. Obstetrics outcome of patients with and without active disease were compared. One hundred patients were included (81 with Crohn's Disease for 198 pregnancies, 19 with Ulcerative Colitis for 37 pregnancies). Patients with active IBD (21 patients, 24 pregnancies) were more likely to be admitted to hospital during pregnancy (66.6, vs. 5.2% in the inactive IBD group; p < 0.001), to give birth prematurely (mean term: 36.77 weeks of amenorrhoea (WA) vs. 38.7 WA, respectively; p = 0.02) and to experience very premature delivery (before 32 WA: 12.5 vs. 1.4%, respectively; p = 0.02). Patients with active disease had a shorter term at birth (38.4 WA, vs. 39.8 WA in the inactive disease group; p < 0.0001), a lower birth weight (2707 g vs. 3129 g, respectively; p = 0.01) and higher caesarean section rate (54.2 vs. 16.9%, respectively; p = 0.03). Women with IBD patients are at risk of pregnancy related complications, especially when IBD is active. Controlling disease activity at conception and close monitoring of the pregnancy is essential to improve both gastroenterological and obstetric outcome.

Impact of precision irrigation on the unit income of maize production

The study of the economic/economic impact of precision farming should be a priority area in digital agriculture, as the results, profitability, and efficiency indicators can have a significant decision-support effect on the development of both the agronomic and the technical regions of individual farms both in the longer and shorter term. Individual firms, companies, farmers, and family farms quantify the effectiveness of their farming processes. The modern age offers the possibility of digitally recording all the elements of farming technology, making it possible to analyse the cost-effectiveness of a farm more effectively and, in some cases, to carry out more detailed analyses. Nevertheless, the number of farms demonstrating their profitability with such precise economic calculations is still minimal. Our analyses were conducted on a 56,02 ha field of Balogh Farm-Tépe Ltd. The agricultural operations carried out were fully documented so that the inputs (seeds, fertilisers, pesticides, crop enhancers) were recorded in coordinates and kind, as well as the specific yields, grain moisture data, irrigation norms, and irrigation rotations. At the same time, the company's owner provided the data's monetary value. The main econometric indicators (yield, production value, cost of production, income, cost price) related to the evaluation of the enterprise management were evaluated along with the spatial data in the irrigated and non-irrigated tables. Our calculations show that a given year's climatic and market characteristics fundamentally determine the cost and income relations of a plot of land (and thus of an entire farm). In addition to additional inputs, introducing some elements of precision farming and intensification and increasing yields improves yield security and allows for excellent yield stability.
