The spread of the COVID-19 pandemic has unprecedentedly affected consumer behaviour. This paper reflects on changes in food consumption, buying, and training (working out) habits using a representative sample of 1000 Hungarian consumers and identifies consumer segments with unique needs based on personal sources of motivation. The widely known Schwartz Portrait Value Questionnaire was used to characterize individual value profiles. Employing k-medians clustering, three clusters were identified. “Business-as-usual People” managed to maintain their daily routines. The frequency of buying local food decreased the least among them. The sedentary lifestyle of the next cluster, “Inactive savers”, appears to have been accompanied by a lower level of food intake. Accordingly, this group was possibly less subject to the negative impacts of obesity, but more in need of psychological support to avoid devastating mental health outcomes. The third cluster initially appeared to encompass “Couch Potatoes” based on their COVID-induced lifestyles. However, the analysis of the value portraits of the latter showed that they were not couch potatoes at all, but rather active and proactive “Stay-at-home Businesspeople” who may benefit from guidance regarding how to manage the increase in housekeeping and childcare, and how to become more physically active in the home environment. The results are valuable from both a scientific and practical perspectives.
Ismail (2022) Evaluation of the effect of biochar-based organic fertilizer on the growth performance of fennel and cumin plants for three years, Environmental Pollutants and Bioavailability, 34:1, 374-384, ABSTRACT This three years field study examined the influence of application rates of manure from sheep and goat (S/G) and their mixture with wood-based or farm yard manure-based biochars (FYMB) on growth performance of Foeniculum vulgare (fennel) and Cuminum cyminum (cumin). The fertilizer amendment rates were 1.66, 3.32 and 6.64 t ha −1 , which were applied for three consecutive years in field. The nitrogen (N) and phosphorus (P), nitrogen use efficiency (NUE) and phosphorus use efficiency (PUE) in seeds and stover of test crops were analyzed for third year cropping only. Results demonstrated that in general, fertilizers did not influence yield of first and second year crops. The significant (P ≤ 0.05) positive influences of organic fertilizers were observed for third year crops and were of higher magnitude for C. cyminum than F. vulgare (126-306.6% increase for C. cyminum and 24.5-48.4% increase for F. vulgare than control). As compared to S/G applied at 6.64 t ha −1 rate, its co-amendment with wood-derived biochar at all application rates significantly reduced P in seeds; whereas, its co-amendment with both biochar types and at all application rates significantly reduced P in the stover of F. vulgare (Table 3; P ≤ 0.05). For the crop C. cyminum, there was no difference between treatments for the concentration of P in stover. The phosphorus use efficiency (PUE) of stover of F. vulgare was significantly improved by 80-108% and by 60-79% in response to the application of S/G and its co-amendment with FYMB respectively than control. The PUE of seeds of F. vulgare was increased by 100% than control in response to the co-amendment of manure with wood-derived biochar at high application rate (P ≤ 0.05). More profound significant improvement in PUE was observed for third year crop of C. cyminum, as most of the treatments improved PUE of seeds by171-561% and stover by 196-294% than control with no significant differences between fertilizer treatments. Results show no relationship between fertilizer application rates and life history trait of crops in space and time, since there was non-consistent and in general non-significant differences between fertilizer treatments for both crops. ARTICLE HISTORY
Applied methods and materials to support regional planning vary; planners update their analytical frameworks based on the newly available data. Development goals, priorities and strategies need to be based on available (local) resources, which are identified as either comparative advantages or uniform development goals at a certain planning level. This paper presents a novel analytical framework for the Rural Development Programme of the South Transdanubian Region (Hungary) for the period of 2021-2027. Descriptive, cross tabulations and indicators of spatial autocorrelation were applied to the number of projects supported under the Rural Development sub-measures in 2014-2020. Large variation was observed in the LEADER development areas, and we confirmed that the pull effect of the regional centres is unclear. The results warn on the location-determined peripheries in the region. Agriculture oriented, even small settlements are better acceptors of rural development funds than other clusters of resource availability.
Do labor productivity, industrial agglomeration, and urbanization coexist in cluster space? To examine this question, we used multiple methodologies. Density-based cluster mapping is used to create the cluster space, simultaneous equation in each cluster to verify the co-existence of agglomeration, LP, and urbanization and, Kohonen self-organizing maps to insightful analyses of these clusters. This article used 18-year county-based data from 2001 to 2018 and analyzes the cluster space in Hungary. Three things emerge out from this study: first, there are seven clusters in space; second, in all seven cluster agglomeration, LP, and urbanization are significantly co-exist and there is bidirectional causality among them; and third, Hungarian manufacturing regions can be classified into two phases of clusters. The manufacturing industrial structure in Hungary is group-specific where one group is in a declining phase and another is in the reindustrialization phase.
Aim: To assess the tendencies of radiation oncologists (ROs) in adjusting radiotherapy treatments (RTH) according to the coronavirus disease 2019 (COVID-19) status of patients during the early severe acute respiratory syndrome coronavirus 2 (SARS-COV2) pandemic in Europe. Material and methods: An electronic survey was sent to 79 academic RTH departments across Europe. Only one respondent per institution was included. Respondents were asked how they would adjust RTH treatments based on COVID-19 status for more common cancers during the first wave of the pandemic. Respondents were also asked to report the number of external beam radiotherapy (EBRT) units and the number of new cases referred to their department. Descriptive statistical analysis was conducted focusing on different cancers. Results: The overall response rate to the survey was 30.38% (24 institutions from 13 European countries). There was a wide range of different institutions regarding the number of patients, radiation oncologists, and facilities. A large proportion of respondents supported adjustment of RTH treatment (delay or switch to a shorter fractionation) for COVID-19-negative patients during the first wave of the pandemic only for early breast cancer (20% delay, 42.3% shorter), prostate cancer (53.6% delay, 21.4% shorter), and benign brain tumours (32% delay, 12% shorter). For COVID-19-negative patients with other cancers, most respondents recommended the standard RTH treatment. For COVID-19-positive patients, most respondents favoured a delay in RTH treatment or a shorter fractionation, regardless of cancer type and stage. Conclusion: The patient's COVID status significantly influenced the decision to undergo RTH treatment, regardless of the type and aggressiveness of cancer.
Why do foreign firms and domestic firms face different hindering factors in a group of the same structural economies and business environment created by the same macroeconomic variables? This study addresses the essential question of the impact of a sound business environment in attracting or deterring foreign direct investment (FDI). This research utilizes the firm‐level World Enterprises Survey (WES) data and employed the parametric and non‐parametric methodology. The binary logistic regression and decision tree have been used to analyze the business environment. The author examines how macroeconomic factors influence the FDI investment decision. It was found that the two models perform very similarly in terms of predicting the business obstacle. Results of this study show that the trade regulation is the area of concern for a sound business environment that is identified by both methods in this study. Countries with stronger contract enforcement and more efficient international trade regulations create a pleasant business environment to attract more FDI.
Banks are leveraging on innovation to address the major concerns of their employees including improvements in service delivery, operational efficiency, and enhancing the speed of transactions. The purpose for this study was to explore the mediating role of job performance and job satisfaction in the relationship between service innovation and organisational performance. Data for the study was obtained from 250 bank employees in Ghana through structured questionnaire. The PLS-SEM was the main analytical tool used to analyse the research findings. Findings from this study revealed a positive and significant relationship between service innovation and organizational performance. Additionally, the study revealed that employee job satisfaction and productivity positively influence organisational performance. The study further revealed a mediation possibility for job satisfaction and employee productivity in the relationship between service innovation and organisational performance. The implications as well as the theoretical contributions of this study are discussed.
This study shows how internal and international migration either it is permanent or temporary migration influences the foreign investors’ interest first in the form of foreign capital inflow, second in the form of agglomeration of foreign investment enterprises, and third in the form of FDI disparity at the county level. Our estimates suggest socio-economic pull factors like GDP per capita, population and production is significant for FDI inflow in Great Plain and North region while in the Transdanubia region, results are varied according to the FDI regional distribution.
Recent researches suggest that functional diversity represents the response of communities to environmental alterations better than taxonomic diversity. However, there is scarce information about how the functional diversity of freshwater fishes is affected by habitat type and the dominance of non-native species. To address this question, we analysed a large database containing 15 morpho-functional traits of 61 fish species from the Pannon Biogeographic region (Hungary). Based on a fish faunistic list and relative abundance of taxa, we quantified the taxonomic and functional diversity of riverine communities for > 700 sites of six habitat types. We asked how non-native fishes affected the taxonomic and functional diversity in different river types and at the local scale (i.e. at the site level), and how the diversity measures of native fauna elements changes along the invasion gradient. Our results showed that both functional and taxonomic richness increases with habitat complexity, from small headwater streams to large rivers. Therefore taxonomic diversity served as a good proxy for functional diversity along the environmental gradient of river types. Non-natives showed considerable functional diversity relative to their species number in each habitat type. Diversity values of native fauna elements initially increased, and then showed a major decrease along the invasion gradient. River type-specific evaluations highlighted the importance of considering the proliferation of invasive species based on both taxonomic and functional diversity indices. We argue that type-specific action plans are needed in conservation management to preserve the taxonomic and functional diversity of native fishes in Hungary, but also elsewhere.
The purpose of the present study was to investigate the effects of different dietary concentrations of ochratoxin A (OTA) on the growth, feed intake, mortality, blood plasma protein content and some parameters of lipid peroxidation and the glutathione redox system of pheasant chicks in a three-week long trial. A total of 320 seven-day-old female pheasants were randomly assigned to four treatment groups ( n = 40 in each), fed with a diet artificially contaminated with OTA [control (<0.02 mg/kg), 0.88 mg/kg, 1.14 mg/kg and 1.51 mg/kg] for 21 days (up to 28 days of age). The pheasant chicks were sacrificed at early (12, 24 and 72 h) and late (7, 14 and 21 days) stages of mycotoxin exposure to check the effect of OTA. Minimal feed refusal was found in the medium- and high-dose toxin groups (–9.8 and –7.9%, respectively), and body weight gain was nearly the same in all groups. The glutathione redox system was activated mainly in the liver, confirmed by significantly increased reduced glutathione content and glutathione peroxidase activity during the late phase of mycotoxin exposure and at a high-dose treatment. The results suggest that pheasants have low susceptibility to OTA, and activation of the glutathione redox system has importance in this tolerance.

Species range expansions and (re)colonization of landscapes variously dominated by humans occur on a global scale. Understanding such range enlargements and subsequent changes in the composition of ecological communities is important for conservation management, and the golden jackal (Canis aureus) can be considered a model species for regional and continental range expansion. Although this mesopredator has been known from the Adriatic Coast of southeastern Europe for over 500 years, the species is a recent arrival further north, including in Slovenia where jackals were first confirmed in the 1950s. Research from eastern Italy found jackals with ancestry from the Dalmatian region on the Adriatic Coast and the Pannonian region further east. We predicted similar ancestry for Slovenian jackals, and examined samples from Croatia, including Dalmatia and interior regions, Serbia, Hungary, and Slovenia with 25 microsatellite markers to determine population genetic structure. We detected two distinct genetic clusters, representing the Dalmatian and Balkan-Pannonian (Pannonian) jackal populations (FST = 0.157, 95% CI: 0.112–0.209). Contrary to expectations, only few individuals in Slovenia exhibited signs of Dalmatian ancestry, and none appeared to be direct immigrants. Some results suggested a third cluster centered in northern Hungary. These divergent profiles might indicate immigration from outside the study area, and samples from regions further east are required for additional resolution. Based on our results, we hypothesize that Dalmatia has not been a substantial source for recent range expansion of the species, which has likely occurred from the east. Further investigation can help resolve the ancestry and current distribution of the Dalmatian and Pannonian populations, and the ecological relationships resulting from progressively overlapping distributions of canid species. Finally, genomic research could illuminate whether genetic variants from eastern areas might have facilitated jackal expansion into regions characterized by a colder climate, the presence of snow, and extensive forest cover; habitats seemingly avoided by the jackals occupying the Adriatic Coast and surrounding areas in southeastern Europe.
This paper explores to what extent product and marketing channel diversification contributed to the economic success of small-scale agricultural producers involved in short food supply chains after the outbreak of the COVID-19 pandemic. A survey was conducted between April and July 2020 in four countries of the European Union-Estonia, Hungary, Portugal and Romania,-resulting in a relatively large sample of farmers (N = 421). The analysis was built on a semi-nonparametric approach. Approximately 19 percent of small-scale producers were able to increase sales during the first wave of the pandemic, although country-level variation was significant. Fruits and vegetables were by far the most popular products. The importance of specific channels varied across countries, but farm gate sales were among the most important marketing channels both before and during the first wave. The importance of channels that were based on digital resources and home delivery increased. Our evidence indicates that diversification was a strategy that paid off, both in terms of marketing channels and different product categories. However, the impact appears to be nonlinear; the initial advantage generated by diversification rapidly tapered off, either temporarily (in the case of products), or permanently (in the case of marketing channels). Later research may clarify whether these findings are generalizable in other socio-economic contexts, as well as in a non-COVID situation.
Consumption of dairy products is one of the most natural ways to introduce probiotics. However, the beneficial effects of the probiotics might depend on the administration form. The aim of this study was to investigate the beneficial properties of two probiotic strains: Bifidobacterium animalis subsp. lactis (BB-12) and Lactobacillus acidophilus (LA-5) in different administration forms (capsules and yogurt). First, in vitro resistance to gastrointestinal condition, surface properties, and immunomodulation capacities were determined. Then, the anti-inflammatory properties of the probiotic strains administrated on yogurt or capsules were tested in a dinitrobenzene sulfonic acid (DNBS)-induced colitis mouse model. The survival rates of BB-12 and LA-5 strains to gastrointestinal conditions were slightly higher when yogurt was used as carrier. They showed most affinity to hexane (no-polar basic solvent) than ethyl-acetate (polar basic solvent). BB-12 showed the higher binding capacity to HT-29, Caco-2, and mucin. Both probiotic candidates suppress the secretion of IL-8 secretion by HT-29-TNF-α stimulated cells. Finally, administration of BB-12 and LA-5 strains improve colitis in mice. They protect against weight loss, inflammation, and hyperpermeability induced by DNBS. However, these anti-inflammatory effects were limited when mice were treated with the probiotic strain on a yogurt matrix. Overall results indicate that BB-12 and LA-5 positive properties are compromised depending on the matrix. Consequently, the selection of an appropriate matrix is an important criterion to conserve the positive benefits of these probiotic strains.
The consumer goods market is characterized by strong competition. Thus, to bind customers to the company, a higher priority needs to be attributed to customer retention measures. Such measures include the loyalty card, but the use of the physical card is declining. To counteract this decline, mobile loyalty cards were developed. The basis for the use of mobile loyalty cards is sufficient consumer acceptance. This work is expected to contribute to the explanation of acceptance in the form of usage behavior. Based on the Technology-Acceptance-Model-2 (TAM2) and the literature, hypotheses were derived and a research model was developed. For model testing, a dataset of 255 participants was generated through an online survey and analyzed using partial least squares structural equation modeling (PLS-SEM). The results show that in addition to financial benefits, convenience benefits and psychological factors also have an influence on acceptance. Furthermore, the usage behavior is not negatively influenced by the expected loss of control over personal data. Based on the findings, indications for marketing implementation are given for the confirmed factors.
The purpose of the present study was to use oxidative stress markers for investigating the effect of zeolite (315 mg/kg of complete feed) in the case of aflatoxin B 1 contamination (92 μg/kg complete feed). In a 21-day feeding trial with broiler chickens, oxidative stress parameters such as conjugated dienes, conjugated trienes, malondialdehyde, reduced glutathione content and glutathione peroxidase activity were not changed significantly by supplementation with this mycotoxin absorbent. The relative gene expression of transcription factors KEAP1 and NRF2 was not modified by the absorbent either. Still, the expression of GSS , GSR and GPX4 genes increased significantly due to the aluminosilicate supplementation. The results suggest that zeolite reduced lipid peroxidation in the blood plasma but not in the red blood cell haemolysate or the kidney. The relative expression of the genes encoding the glutathione redox system also changed as a result of zeolite supplementation, but these changes were not found at the protein level.
The ectoparasitic mite, Varroa destructor , is a most important health risk for European honey bee subspecies (Apis mellifera) globally. There is a scarcity in experimental approaches addressing this issue by using computed tomography. Our purpose was to determine the decrease in the volume, surface, density and weight alteration triggered by V. destructor in pre-imaginal stages of A. mellifera using computer-based 3-D reconstruction technology. Computer tomography used in the current study proved to be sufficiently sensitive for the detection of V. destructor in comb cells. This non-invasive experimental setup revealed that the developing worker pupae have retained their volume and surface values, whereas the weight loss triggered by V. destructor was statistically confirmed. In addition, the disappearance of lower radiodensity tissues is shown to be due to mite parasitism, which can be primarily explained by haemolymph losses. computer tomography / pre-imaginal development / honey bee / impairment / Varroa destructor
en The Covid‐19 pandemic has fundamentally reshaped our lives. Its effects on the sales and use of marketing channels of small‐scale Hungarian producers are addressed here. Based on the level of proximity, sales channels were classified into three types. Due to local regulations concerning restrictions on movement, it was only impersonal (online) channels that survived, or the opposite type, i.e. very personal ones involving the face‐to‐face meeting of producers and consumers in the private spaces (mostly homes) of one of the parties. Results from the survey of 136 producers reveal that 60 per cent suffered an economic loss due to loss of sales, while 10 per cent increased their sales. Successful producers were those lucky enough to be operating within the fresh fruit and vegetable sector, within which consumer demand increased significantly. The parallel use of several sales channels before the virus outbreak increased subsequent chances of success by increasing the probability that some of the channels would remain operational. Furthermore, successful producers had invested a lot of work pre‐Covid into maintaining private relationships with their customers; a situation that proved vital during times of restrictions. Also, the former moved fast, and were open enough to learn and make use of the opportunities modern technology offered them. Abstract fr La pandémie de Covid‐19 a profondément remodelé nos vies. Cet article examine ses effets sur les ventes et l'utilisation des circuits de commercialisation des petits producteurs hongrois. En fonction du niveau de proximité, les canaux de vente ont été classés en trois types. En raison des réglementations locales concernant les restrictions de circulation, ce ne sont que des canaux virtuels (en ligne) qui ont survécu, ou du type opposé, c'est‐à‐dire des canaux très personnels impliquant la rencontre en face à face de producteurs et de consommateurs dans des espaces privés (principalement à domicile) de l'une des parties. Les résultats de l'enquête auprès de 136 producteurs révèlent que 60 pour cent ont subi une perte économique en raison de la baisse de leurs ventes, tandis que celles‐ci augmentaient pour 10 pour cent d'entre eux. Les producteurs qui réussissaient étaient ceux qui avaient la chance de travailler dans le secteur des fruits et légumes frais, dans lequel la demande des consommateurs a augmenté de manière significative. L'utilisation parallèle de plusieurs canaux de vente avant l’épidémie de virus a augmenté les chances de succès ultérieures en augmentant la probabilité que certains des canaux restent opérationnels. En outre, les producteurs prospères avaient investi beaucoup de travail avant la pandémie pour maintenir des relations privées avec leurs clients; une situation qui s'est avérée vitale en période de restrictions. En outre, ces producteurs ont évolué rapidement et étaient suffisamment ouverts pour apprendre et profiter des opportunités que la technologie moderne leur offrait. Abstract de Die Covid‐19‐Pandemie hat unser Leben grundlegend umgestaltet. Ihre Auswirkungen auf den Absatz und die Nutzung von Marketingkanälen durch Kleinerzeuger und Kleinerzeugerinnen in Ungarn werden hier behandelt. Die Marketingkanäle wurden je nach räumlicher Nähe in drei Typen eingeteilt. Infolge der lokalen Vorschriften zur Einschränkung der Bewegungsfreiheit überlebten nur die unpersönlichen (Online‐)Kanäle oder der umgekehrte Typ, d.h. sehr persönliche Kanäle. Hier trafen sich Produzentinnen und Produzenten mit ihrer Kundschaft in den privaten Räumen (meist zu Hause) einer der beiden Parteien. Die Ergebnisse einer Umfrage unter 136 Produzierenden zeigen, dass 60 Prozent aufgrund von Umsatzeinbußen einen wirtschaftlichen Verlust erlitten, während 10 Prozent ihren Umsatz steigern konnten. Erfolgreiche Produzierende waren diejenigen, die das Glück hatten, im Frischobst‐ und Gemüsesektor tätig zu sein, in dem die Nachfrage deutlich zunahm. Die parallele Nutzung mehrerer Absatzkanäle vor dem Ausbruch des Virus erhöhte die späteren Erfolgschancen, da die Wahrscheinlichkeit, dass einige der Kanäle auch später funktionsfähig blieben, zunahm. Außerdem hatten erfolgreiche Produzierende vor dem Ausbruch des Virus viel Arbeit investiert, um die privaten Beziehungen zu ihrer Kundschaft aufrechtzuerhalten. Dies erwies sich während der Zeit der Einschränkungen als wesentlich.
