A sector-based nonparametric decomposition of economic growth
Authors: Walheer Barnabe
Published: March 2020

Sectors have gained in importance when studying economic growth and convergence of countries. In this letter, we suggest a simple and intuitive nonparametric procedure to obtain the decomposition of economic growth of countries in terms of sector-level indicators. It turns out that the new decomposition can be used to investigate the role of the sectors in the economic growth and convergence of countries. We propose an application to the case of 19 countries and nine sectors in Europe.

A(ho)rmar la lengua del poema: Ángel González o la dinámica del código
Authors: Le Bigot Claude
Published: March 2020

Resumen: Este artículo pretende examinar la evolución del lenguaje poético de Ángel González, especialmente la transición desde los modelos codificados dentro de una tradición bien asentada (lira, canción, romance, soneto, elegía) hasta una subversión de las formas que, si bien se emparentan con el versolibrismo, mantienen lazos con lo canónico, no haciendo más que duplicar recursos surgidos con la modernidad: versos escalonados, sangrados, guiones. Todo lo que permite agujerear el texto es también portador de ritmo. La oposición medida / encabalgamiento, factor tensional de antiguo abolengo, se regenera bajo la pluma de Ángel González, al lado de otros procedimientos sintácticos, para crear una voz propia en la que se interpenetran lo culto y lo popular. Existe en Ángel González una forma de oralidad, inseparable del ritmo, como articulación de un hablante con su decir. Palabras clave: Ángel González; formas codificadas; ritmo; signos gráficos; versolibrismo. Abstract: This contribution proposes to examine the evolution of poetic language in Ángel González’s works, in particular the transition from models codified by a long-established tradition (lira, ballad, romance, sonnet, elegy) to a subversion of forms which —although it is akin to free verse— still borrows from the canonical form and seeks to tap literary processes born of modernity: stepped lines, blank spaces, dashes. Anything that allows to space out the text becomes a constitutive element of rhythm. Under Ángel González’s pen, new life is breathed into the antithesis between beat and enjambment, a long-established source of tension, revisited thanks to other syntactic devices so as to create an idiosyncratic voice commingling the erudite and the popular. A form of orality exists in Ángel González which is inseparable from rhythm as articulation between the poetic voice and its spoken word. Key words: Ángel González; canonical forms; rhythm; typographic signs; free verse.
Cultivar un vacío secreto: poesía y silencio en José Ángel Valente y Roberto Juarroz
Authors: Saldaña Sagredo Alfredo
Published: March 2020

Resumen: José Ángel Valente y Roberto Juarroz fueron dos poetas que mantuvieron una relación radical con el lenguaje, al margen de grupos y movimientos generacionales. Ambos se entregaron con una severidad extrema a un proyecto similar de estiramiento de los límites de las palabras y encontraron en la nada y el vacío, antes que representaciones de una cierta negatividad, oportunidades de generación de nuevos sentidos. En uno y otro encontramos una palabra impulsada por un pensar que no termina de cerrarse, un lenguaje orientado hacia la explosión y la apertura, y entendido como un proyecto armado a través de la duda y la interrogación permanentes, la búsqueda del sentido y la desconfianza frente a cualquier tipo de destello identitario. Palabras clave: Poesía contemporánea; José Ángel Valente; Roberto Juarroz; silencio; vacío. Abstract: Away from groups and generational movements, José Ángel Valente and Roberto Juarroz were two poets who maintained a radical relationship with language. With extreme severity, both creators engaged in a similar project to stretch the limits of words, and found opportunities to generate new meanings in nothingness and emptiness, instead of relying on depictions of certain negativity. In one and the other a word driven by a thinking that does not reach its closure, a language oriented towards explosion and openness can be found. A project that is armed through permanent doubt and questioning, through the search of meaning and distrust in front of any type of identity flash. Key words: Contemporary poetry; José Ángel Valente; Roberto Juarroz; silence; emptiness.

Authors: Al-Hariri Mohammed T. , Eldin Tharwat G. , Hashim Tarek , Chathoth Shahanas , Alswied Abdullah
Published: March 2020

ABSTRACT: Objectives: This study aimed to determine the effects of propolis on immune mediators and tissue histopathology in rats with L-arginine-induced acute pancreatitis (AP). Methods: This study was conducted at Imam Abdulrahman Bin Faisal University, Dammam, Saudia Arabia between September and November 2017. A total of 24 male albino Wistar rats were divided into three equal groups. Group one was the negative control, group two was the positive control (L-arginine-induced AP) and group three received treatment (L-arginineinduced AP and propolis). The rats in group three were treated with 100 mg/kg propolis for seven days after AP induction. Pancreatic tissue was evaluated histologically and levels of interleukin (IL)-6, IL-22 and IL-1β and tumour necrosis factor-alpha (TNF-α) were measured. Results: Propolis reduced the quanitity of proinflammatory molecules (TNF-α, IL-1β and IL-6) in group three compared to group two, significantly increased the overall anti-inflammatory effect of IL-22 (P <0.005) and reduced interstitial inflammation and neutrophil cell infiltration of the pancreatic tissues. Conclusion: Propolis may exert a therapeutic effect in AP. Further studies are required to demonstrate the mechanisms of propolis in AP.Keywords: Propolis; Arginine; Pancreatitis; Interleukins; Cytokinesis; Rats; Saudi Arabia.

Published: March 2020

Objectives: Triple-negative breast cancer (TNBC) is one of the most aggressive and heterogeneous variants of breast cancer. However, little is known regarding the prevalence and outcome of this entity in the Middle East. This study aimed to evaluate the outcomes of TNBC patients at a university hospital in Oman. Methods: This retrospective study took place at the Sultan Qaboos University Hospital, Muscat, Oman, in May 2017. All patients diagnosed with non-metastatic TNBC between December 2000 and December 2015 were included. The patients’ electronic medical records were reviewed to identify their clinical and pathological characteristics as well as survival outcomes. Results: A total of 79 patients were diagnosed with non-metastatic TNBC during the study period. The median age was 46 years, with approximately one-third of patients (31.6%) under 40 years of age. Almost half had an advanced tumour size (49.4%) or node-positive disease (48.1%) at presentation and only 16.6% demonstrated a complete pathological response (pCR) to neoadjuvant chemotherapy. The median survival for all patients was not reached within the study period; however, the median overall survival for stage III patients was 44.6 months. The five-year overall survival for all patients was 64%, increasing to 100% and 72% for patients with stage I and II, respectively, and dropping to 47% for those with stage III disease. Conclusion: The findings of this study indicate that the majority of women with TNBC in Oman present at an advanced stage; moreover, such women have low rates of pCR to neoadjuvant chemotherapy and poor five-year survival.Keywords: Breast Cancer; Triple-Negative Breast Cancer; Neoadjuvant Therapy; Survival; Patient Outcome Assessment; Oman.
The Value of Programmed Death Ligand 1 Expression in Cancer Patients Treated with Neoadjuvant Chemotherapy
Authors: Al-Dughaishi Malika , Shalaby Asem , Al-Ribkhi Khawla , Boudaka Ammar , Boulassel Mohamed-Rachid , Saleh Jumana
Published: March 2020

Programmed death ligand 1 (PD-L1) is an inhibitory molecule expressed by cancer cells to supress T-cell activity and escape anti-tumour immunity. The role of PD-L1 in cancer has been studied extensively as it is considered an important immune checkpoint against immune over-activation through its interaction with Programmed death receptor 1 (PD-1) expressed on activated lymphocytes. PD-L1 expression was found to be enhanced by chemotherapy through different proliferation pathways. However, the predictive and prognostic value for PD-L1 expression in cancer patients treated with neoadjuvant chemotherapy (NAC) is not yet established. This review focused on the potential effects of chemotherapy on PD-L1 expression and the role of PD-L1 as a prognostic and predictive marker in NAC-treated cancer patients. In addition, the potential use of this marker in clinical practice is discussed.Keywords: Programmed Cell Death 1 Ligand 1; Programmed Cell Death 1 Receptor; Neoadjuvant Therapy; Cancer.

Lactation ketoacidosis is an extremely rare type of high anion gap metabolic acidosis. We report two lactating women who were diagnosed with lactation ketoacidosis. The first patient presented to the Emergency Department at Royal Darwin Hospital, Darwin, Australia, in 2018 with lethargy, nausea and abdominal pain after she commenced a new diet regimen based on three meals of protein per day and free of glucose, gluten and dairy products. The second patient presented to the Emergency Department at Sultan Qaboos University Hospital, Muscat, Oman, in 2018 with headache, severe malaise, epigastric pain and worsening of gastroesophageal symptoms. Blood investigation results showed that both patients had high anion gap metabolic acidosis, ketosis and hypoglycaemia. The patients responded well to intravenous dextrose and resumption of a balanced diet. Both patients were able to continue breastfeeding and remained well on follow-up.Keywords: Breastfeeding; Starvation; Hypoglycemia; Ketosis; Acid-Base Imbalance; Metabolic Diseases; Ketone Bodies; Fasting; Case Series; Australia; Oman.

Prevalence and Factors Influencing Use of Herbal Medicines During Pregnancy in Hail, Saudi Arabia: A cross-sectional study
Authors: Aljofan Mohamad , Alkhamaiseh Suhaib
Published: March 2020

Objectives: The increasing prevalence of herbal medicine use is a global public health concern. Critically, many women continue to use herbal medicines during pregnancy despite potential maternofetal risks. The current study aimed to determine the prevalence of and factors associated with herbal medicine use during pregnancy in Saudi Arabia. Methods: This cross-sectional study was conducted between February and May 2017. An Arabic-language 33-item survey assessing herbal medicine use was designed and distributed to 879 random women attending outpatient clinics at governmental and private hospitals in Hail, Saudi Arabia. Only women who were pregnant or had been pregnant in the previous 10 years were included. Results: The mean age of the participants was 29.5 years, with 49% under 30 years old. Overall, 33% of the respondents claimed to have used herbal medicines during pregnancy. The most common reasons for doing so were to improve lactation (73%), improve the course of the pregnancy (56%) and facilitate labour (49%). Women who worked full-time and those with high school diplomas or above were significantly more likely to use herbal medicines during pregnancy (P <0.001 each). Conclusion: To the best of the authors’ knowledge, this is the first study to determine the prevalence and associated factors of herbal medicine use during pregnancy in Hail. The results showed a high prevalence of herbal medicine use among pregnant women in the region. Healthcare providers should therefore ensure that patients disclose the use of herbal medicines during pregnancy to avoid treatment complications or adverse herb-drug interactions.Keywords: Herbal Medicine; Plant Preparations; Pregnancy; Complementary Therapies; Health Behaviors; Prevalence; Herb-Drug Interactions; Saudi Arabia.

Authors: Al-Nimr Yumn M. , Farhat Ghada , Alwadey Ali
Published: March 2020

Objectives: Smoking is one of the most adaptable risk behaviours associated with increased mortality rates, yet over one billion individuals worldwide are smokers. This study aimed to examine self-reported reasons for starting and quitting smoking among women attending smoking cessation clinics in Saudi Arabia. Methods: This cross-sectional study took place between January 2014 and January 2017 in Saudi Arabia using previously collected data. A survey was distributed to 3,000 female smokers attending smoking cessation programmes in 18 clinics from different regions in Saudi Arabia to determine self-reported reasons for smoking initiation and willingness/unwillingness to quit. Results: A total of 2,190 women participated in the study (response rate = 73%). Overall, the most common reason for starting to smoke was friends (31.1%), while the predominant reason for willingness to quit was health concerns (45.5%). The most frequent reason for being unwilling to quit smoking was a fear of mood changes (28%). Conclusion: Most Saudi women are socially-driven to start smoking, while the most common reason for quitting is health concerns. The latter finding is promising in that it shows that smokers are gaining awareness of the adverse effects of smoking.Keywords: Tobacco Smoking; Smoking Cessation; Health Risk Behaviors; Lifestyle Risk Reduction; Primary Health Care; Saudi Arabia.

Published: March 2020

Background and Purpose: Candida parapsilosis complex isolates are mainly responsible for nosocomial catheter-related infection in immunocompromised patients. Biofilm formation is regarded as one of the most pertinent key virulence factors in the development of these emerging infections. The present study aimed to compare in vitro antifungal susceptibility patterns and biofilm-related genes expression ratio in planktonic and biofilm’s cells of clinically C. parapsilosis complex isolates.Materials and Methods: The current study was conducted on a number of 17 clinical C. parapsilosis complex (10 C. parapsilosis sensu stricto, 5 C. orthopsilosis, and 2 C. metapsilosis). The antifungal susceptibility patterns of amphotericin B, fluconazole, itraconazole, voriconazole, posaconazole, and caspofungin in planktonic and biofilm forms were closely examined using CLSI M27-A3 broth microdilution method. The expression levels of biofilm-related genes (BCR1, EFG1, and FKS1) were evaluated in planktonic and biofilm’s cells using Real-time polymerase chain reaction (PCR) technique.Results: The obtained results indicated that all C. parapsilosis complex isolates were able to produce high and moderate amounts of biofilm forms. In addition, the sessile minimum inhibitory concentrations were reported to be high for fluconazole (≥ 64 μg/ml), itraconazole, voriconazole, and posaconazole (≥ 16 μg/ml), as compared to planktonic minimum inhibitory concentrations. Moreover, a significant difference was observed between antifungal susceptibility patterns for all azole antifungal agents (P<0.05). Furthermore, the BCR1 overexpression was considered significant in biofilms with regard to planktonic cells in C. parapsilosis species complex (P=0.002).Conclusion: C. parapsilosis complex isolates were found susceptible to most of the tested antifungal drugs, while biofilms demonstrated a noticeable resistant to azoles. The marked discrepancy noted in antifungal susceptibility patterns among these species should be highlighted to achieve effective therapeutic treatment.

Published: March 2020

Background and Purpose: Despite the various applications of Satureja species, there are limited data in this domain. Regarding this, the present study was conducted to investigate the essential oil (EO) biological activity of S. macrosiphon species in Iran.Materials and Methods: The EO of S. macrosiphon flowers was obtained by hydrodistillation. Chemical compositions of the EO were analyzed using gas chromatography-mass spectrometry. In addition, minimum inhibitory concentrations (MIC) were measured by means of the broth microdilution method. The estimation of antibiofilm and cytotoxic activities was also accomplished using the tetrazolium salt and MTT assays, respectively.Results: A total of 26 components were identified in the EO with linalool as the main constituent (28.46%). A MIC range value of 0.25-8 μL/mL was obtained against all of the tested fungi. The EO inhibited the biofilm development of the Candida tested strains at a concentration of 4-8 μL/mL. Cytotoxicity (IC50) of EO against the HeLa cell was greater than the MIC concentration (6.49 μL/mL).Conclusion: Based on the findings, it was concluded that the EO of S. macrosiphon has the potential for further use as an antifungal agent.

Authors: Rohilla Ranjana , Meena Suneeta , Kaistha Neelam , Krishna Raj Anusha , Gupta Pratima
Published: March 2020

Background and Purpose: We report a case of disseminated cryptococcosis in a treatment-naïve patient, incidentally diagnosed with hepatitis C virus (HCV) infection and renal parenchymal disease. The patient succumbed to death given the very late diagnosis of the disease.Case report: A 54-year-old male presented with the chief complaints of abdominal pain, chest pain, and phlegmy cough for a month. There was a past history of decreased urine output, lower limb swelling, and fever lasting for 15-20 days. After a general physical examination, the differential diagnosis of hepatitis C-related liver disease with hepatic encephalopathy, disseminated tuberculosis, and septic shock was made. Radiological examination revealed renal parenchymal disease on ultrasound abdomen and opacity with reticulonodular opacity in the bilateral lung zones. In laboratory investigations, serum reactive sample was tested for anti-HCV antibodies. In addition, Cryptococcus var grubii was identified in blood culture using the matrix-assisted laser desorption ionization-time of flight mass spectrometry (Bruker Daltonics, Germany). The patient succumbed to death before the initiation of any specific antifungal therapy.Conclusion: Cryptococcosis-HCV co-infection is a fatal condition with a fulminant course that might be difficult to treat.

Published: March 2020

En este artículo se reportan los resultados de un proyecto de investigación que indaga sobre lo que ocurre en la dinámica del aula, en relación con los procesos de comunicación y de interacción, cuando se emplean metodologías que consideran el uso de tecnología móvil. Como objetivo general se pretendió evidenciar el papel que las y los estudiantes desempeñan en los procesos de aprendizaje, y el que perciben que les corresponde desarrollar, cuando se emplean metodologías que consideran el uso de ese tipo de tecnologías. Además, se estudió el papel que la docente desarrolla, y el que percibe que le corresponde desempeñar, en este tipo de contextos educativos.Los resultados develan que la cultura organizacional ofrece elementos que pueden afectar un proceso de innovación educativa como el que supone la incorporación de los iPad como recurso didáctico. Además, la escogencia de un curso como el propuesto no siempre responde al interés del estudiantado y ello afecta su motivación para el desarrollo de actividades críticas dentro de la clase. Por otro lado, la formación de los docentes para el emprendimiento de innovaciones educativas, como el que supone el uso de iPad en la enseñanza de la matemática, requiere no solo del manejo correcto de los dispositivos y de las metodologías didácticas pertinentes, sino que debe prepararle para desarrollar su labor en un ambiente cargado de incertidumbre, en el que el desempeño actitudinal de algunos estudiantes puede diferir del esperado y enfrentar presiones porque el proceso de innovación desafía elementos de la cultura organizacional instalada.

Abstract

This paper reports the results of a research project about what happens in classroom dynamics related to communication an interaction processes using mobile technology methodologies. The first objective was to show the student?s role in the learning processes when using mobile technology methodologies and the one that they perceive to be developed. In addition, we studied the teacher’s role and the one that she perceives has to play in this educational context.Results reveal organizational culture elements that can affect an educational innovation process such as incorporation of iPad as a didactic resource. This kind of course does not always respond to the student's interests what affect his (her) motivation of critical activities inside the classroom. Training teachers to develop educational innovations, such as the use of iPad into mathematics lessons, requires more than just knowing the correct handle of mobile devices, it demands working in an environment full of uncertainty. The attitudinal performance of some students may differ from the expected and they get pressure because the challenges elements of the innovation process and those stablish by the organizational culture.
Actividades de Tablas Estadísticas en Textos Escolares de Matemáticas
Authors: Salcedo Audy
Published: March 2020

En este trabajo se analizan las actividades de tablas estadísticas de una colección textos escolares de Matemáticas. El texto escolar de Matemáticas es uno de los recursos que usan los docentes como una guía para la enseñanza y fuente de actividades para el estudiante, de allí la importancia de investigar sobre los libros. Se realizó un análisis de contenido para clasificar las actividades según el tipo de tabla, el rol que asume el estudiante cuando trabaja con la tabla y el nivel de lectura que se le exige en cada actividad de interpretación de tabla. Los resultados evidenciaronque todas las actividades de tablas en la primaria son de una entrada, mientras que en secundaria son de dos entradas. En cuanto al rol que asume el estudiante, las actividades son fundamentalmente para interpretar tablas, aunque solo se encuentran en dos grados. En primaria, las actividades exigen la lectura integral de la tabla, mientras que en secundaria, deben hacer lecturas parcial e integral de la tabla. En conjunto, no parece que las actividades de tablas estadísticas, de la colección analizada, puedan ayudar a los estudiantes a lograr una compresión adecuada de ese recurso de la estadística y con ello apoyar su formación estadística como ciudadano.

Abstract

 In this paper we analyze the activities of statistical tables of a collection of textbooks of mathematics. The textbook of mathematics is one of the resources used by teachers as a guide for teaching and source of activities for the student, hence the importance of researching books. A content analysis was carried out to classify the activities according to the type of table, the role that the student assumes when working with the table and the level of reading is required in each table interpretation activity. The results showedthat all the activities of tables in the primary are of one entry, while in secondary they are of two entries. As for the role of the student, it is fundamentally to interpret tables, although they are only in two grades. In primary, the activities demand the integral reading of the table, while in secondary, they must make partial and integral readings of the table. On the whole, it does not seem that the activities of statistical tables, of the analyzed collection, can help students to achieve an adequate understanding of this resource of statistics and thereby support their statistical training as citizens.
Are bisphosphonates a more effective treatment than intra-articular steroids in horses with distal hock osteoarthritis?
Authors: Greene Hannah
Published: March 2020

PICO question

In horses that are lame due to osteoarthritis of the distal tarsal joints (bone spavin), is intra-articular medication with corticosteroids compared to systemic bisphosphonate treatment more effective in long-term lameness reduction?

 

Clinical bottom line

Category of research question

Treatment

The number and type of study designs reviewed

Three papers were critically reviewed. Two were randomised controlled trials, and one was a retrospective study.

Strength of evidence

Weak

Outcomes reported

There is insufficient evidence to support the use of systemic bisphosphonates over intra-articular corticosteroids to treat distal hock osteoarthritis in horses.

Conclusion

Horses with distal hock osteoarthritis should not be treated with systemic bisphosphonates until further blinded randomised controlled trials are completed. Additionally, supportive evidence for the use of intra-articular corticosteroids as a treatment for degenerative hock osteoarthritis is limited to a retrospective study where modest, short-term improvements are reported: 58% of horses improved after an average of 56 days (Labens et al., 2007). Evidence does not support significant improvement in long-term outcomes: 50% of horses improved after 4 months (Watts et al., 2016) and only 38% of horses improved after a mean follow-up period of 787 days (Labens et al., 2007).

 

How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

Subsidies are Potential Sources of Profitable Management – Their Payment Between 2010 and 2016
Authors: Jávor Bence , Nábrádi András , Kukovics Sándor
Published: March 2020

Based on the allocations and distributions of subsidies in the sheep sector in the previous years (2004-2009), the authors examined the sum of aids claimed and paid from 2010 to 2016 and their farm-size related changes. The following data were collected from the Agricultural and Rural Development Institute on payments under specific subsidy titles, classified by sheep and goat farm sizes: 0-50; 51-100, 101-200, 201-300 and also 0-100, 101-300, 301-500, 501-1000, 1001-5000 and above 5000. Data procession was carried out by the SPSS for Windows 22 program. The size and population of the examined sheep sector underwent visible changes during the studied years leading to a reduction rather than growth. Their analysis highlights that size distribution of sheep farms has changed significantly in recent years, combined with simultaneous modifications of their sheep stock sizes in production. Their conclusions suggest that effects of years and farm sizes in the sheep and goat sector have considerably modified the aid sums paid under different titles.

Structural Breaks or Continuous Adjustments in Grain Production and Prices 1961-2014? An Explorative Study
Authors: Fretheim Torun
Published: March 2020

This article analyses grain production and prices 1961-2014. We first describe the development in aggregated and relative allocation of land worldwide for wheat, corn and soybeans, and the growth in production volumes and yields. We then proceed by analyzing long-term price relationships. Finding that grain prices are strongly co-integrated, we estimate an Error Correction Model to see whether deviations from the long-run equilibrium are quickly adjusted. Furthermore, we investigate whether changes in land allocations for these principal field crops are best described as a continuous process or as a series of structural breaks, hypothesizing that events like the introduction of GM technologies and the “energizing” of corn after 2005 caused structural breaks in acreage shares and relative prices. Given the major and sometimes dramatic political events and technological changes during this period,one would expect to find significant structural breaks in grain production, yields and prices. However, our main conclusion is that grain markets generally adjust smoothly and continuously. Prices adjust quickly towards long-run equilibrium, and the results from a series of Chow tests indicate that the changes in relative land allocations have progressed as a relatively smooth process with few structural breaks.

Authors: Tobak Júlia
Published: March 2020

We can talk about family business if the notions of family, ownership and business are closely connected to each other, namely if the business is in the possession of the family, managed and controlled by the family members. A family owned company is a business where a family has the majority ownership and/or the majority management and at least one family member actively works in the firm, the family owns the business. The study contains the results of research on ownership structure of family owned businesses. The examined family businesses are interested in longterm preservation of values, thus succession of generations plays a key role in their case. They attaches great importance how the ownership structure develops. The methotology to know more about the ownership structure of family businesses 11 expert interviews were made between november 2016 and september 2017 with owners and next generations of family owned agri-food enterprises in Hungary. A case study has been prepared too in this topic with the participation of companies with different activities (production, service, trade). In order to classify the analysed companies six categories of ownership were developed. These are non-owner, emotional owner, partial owner, controlling owner, majority owner and exclusive/ sole owner. Each generation of the analysed FBs were classified to these categories. According to the results the analysed family owned companies even are sharing the property within family. There are only two interviewed companies whose case we can talk about exclusive/sole ownership.

Trends on the Artificial Fertilizer Market and in Fertilizers Use in Hungary
Authors: Ács Gergő
Published: March 2020

The fertilizer market in Hungary is rather concentrated, which has a strong influence on the price of the fertilizer. Our domestic fertilizer use is primarily determined by that of nitrogen. The use of phosphorus is also significant but the trends in the use of potassium do not match the total quantities applied in individual years. Consequently, it can be concluded that the majority of farmers still focus on the application of nitrogen and also apply phosphorus but either neglect or do not pay enough attention to potassium fertilization. The changes in fertilizer prices between 2006 and 2017 can be broken down into two periods. Until 2012 a very important and dynamic increase was observed as a result of which the prices of N, P and K fertilizers increased by 80-120%, 160% and about 120%, respectively. This was followed by a downturn in the market and in relation to 2012 prices there were 20-30/ decreases experienced until 2017 but the rate of this lagged behind the prices in other European countries. Owing to this trend the prices of N, P and K have increased by 60%, 100% and 80%, respectively, over the past ten years. The correlation between fertilizer application and the prices of fertilizers in any given year is low but there is a positive one observed between fertilizer application and the fertilizer prices in the preceding year. This means supposedly that farmers mostly buy the fertilizers they wish to apply not in the current but in the preceding year and store them until these are applied. There is a strong correlation seen between fertilizer prices and the prices of corn and wheat, which means that fertilizer traders also keep tabs on economic results and also increase fertilizer prices under the influence of higher prices. Furthermore, it can be claimed that there is no correlation between crude oil prices on the world market and domestic N fertilizer prices. This is an important factor since the primary base material of N fertilizers is natural gas and their production involves considerable energy costs as well. It can be seen, however, that this is not what determines our domestic fertilizer prices, which can be explained by the fact that the price calculations by the determining actors on the Hungarian fertilizer market is not based on costs but on the demand.

The Opinion of Visitors on the Touristic Attractions and Services of the Esterhazy Castle of Fertőd
Authors: Bodrogai László A. , Szigeti Orsolya
Published: March 2020

The lately renovated Esterhazy Palace is one of Europe’s biggest Baroque palaces. This paper examines the visitors’ opinion of this worldwide famous palace. This survey-based study was carried out in 2016/2017. The sample was of 800 people, using paper-based questionnaire. It emerged from the study that the visitors needed to be separated analyzed differently under and above 18 years of age, because the push and pull factors vary significantly. Other words, the adult visitors (persons, families) decided themselves to go and see or not, but the young people were influenced by their teachers. Other important lessons of the study was that the visiting process does not end with the viewing of rooms and tools, but the different souvenirs and providing further information, and services are also part of it. This is evidenced by the fact that the worst rating was given by the related service. Organizing and ensuring this is an important task of the management of the palace.

Public Work - an International Outlook
Authors: Cseh-Papp Imola , Wiwczaroski Troy B. , Csapóné Riskó Tünde
Published: March 2020

Labour market policy includes active and passive labour market programmes, aiming to solve different problems. Active labour market programmes assist the unemployed to find jobs and thus return to the labour market. Passive labour market programmes assist the unemployed by providing various kinds of aid, easing social tensions. Public work can be considered to be an active labour market programme, assisting people who receive social care with income based on public beneficial work. Consequently, public work is justified by some on the basis that it is purported to have some kind of moral foundation, as well as because it supposedly shows results within a short time. Yet, the rationale behind using public work programmes to fight unemployment is contested. Detractors see them as being rather costly, questioning their success and arguing that their overall results are uncertain, especially in the long run. In short, there are in fact pros and cons to using public work, with opinions being rather divisive. This study summarises these pros and cons, analysing the relevant international and Hungarian literatures in the context of active labour market programmes.

A Quantitative Assessment of the Rurality and an Efficiency Analysis of Emigration in Romania
Authors: Galluzzo Nicola
Published: March 2020

In Romania, as in many other Eastern European countries, the early 1990s were marked by a significant emigration from the countryside as a consequence of the transition from a centralised economy to an open one and due to key changes in the political framework. The permanent emigration has predominantly been concentrated in rural areas where multiple socio-economic variables such as GDP per capita, unemployment, and public financial subsidies aimed at supporting people at risk of severe deprivation and poverty have all had a direct effect on rural depopulation. The rurality is a complex theoretical construct comprising many items and variables and is, therefore, difficult to define in a concise manner. The aim of this paper is to assess the evolution of emigration in Romania between 2001 and 2016 through a quantitative approach, estimating an index of rurality for the same period composed of a set of socio-economic variables having a direct or indirect nexus to it. In the first phase of research, a matrix of correlation and a multiple regression model has been used in order to estimate the direct links among all investigated variables. Following the quantitative methodology, in the second phase Partial Least Square Structural Equation Modelling (PLS-SEM) has been used in order to assess the main cause-effect relationships among a few selected endogenous variables and a set of socio-economic items. Furthermore, using a non-parametric Data Envelopment Analysis (DEA) output-oriented model, this research has assessed the efficiency in terms of permanent emigration from Romania estimated as an output to minimise and not as an output to maximise, as investigated by traditional efficiency approaches. In terms of efficiency, financial subsidies allocated by national authorities and the level of per capita Gross Domestic Product have acted directly on the level of emigration. The index of rurality in 2016 has been influenced in particular by he pluriactivity in farms in terms of agritourism, the dimension of farms in terms of land capital endowment, and the level of GDP per capita.

Published: March 2020

This study assessed the moderating effect of training and development on entrepreneurial performance of Micro, Small and Medium Enterprises (MSMEs) in Nigeria considering the Bank of Industry and Small and Medium Enterprises Development Agency of Nigeria (SMEDAN). Two hypotheses were tested in this study reflecting training and development in Nigeria and Ethical practices of Training and Development impacts on behavioral outcomes of entrepreneurs. The paper puts to test, the preceding assertions with the aid of Kruskal Wallis test. From the test, the study refutes the former assertions on the reasoning that P-values were less than 5% level of significance. This showed that the impact of ethical training and development would be more significant if the young entrepreneurs had earlier exposure from secondary to tertiary education level to make better entrepreneurs in Nigeria. The study observed that the Nigerian educational system has contributed positively to the area of training and development which has enhanced entrepreneurial performance in Nigeria. The study recommends that training and development programme should focus on developing creative or innovative individuals who can help to move the nation forward. A Self-reliant person is a creative individual.

What is the Success of High School it Education? An Investigation into Higher Education Students’ Knowledge of Spreadsheet Applications
Authors: Bakó Mária , Gergely Ráthonyi
Published: March 2020

Teaching Computer Science in higher education is imperative, even though today’s students have been born into a world where technology is an essential part of everyday life. To efficiently master modern, business, technical and scientific knowledge and to proficiently produce quality results in a work environment it is crucial to have high level IT knowledge. In business, Excel is the lingua franca and so knowing how to aptly use spreadsheets is a must for our students. The primary objective of the authors was to examine the perceived and actual knowledge of spreadsheet applications of students entering higher education. Accordingly, a questionnaire and a practical assignment have been developed. In the questionnaire, students were asked to provide information concerning their previous IT studies and rate their knowledge of word processing, spreadsheets and database management. During the practical, students were asked to solve an Excel exercise taken from a high school Computer Science final exam at standard level. Out of the 666 registered students on our electronic education system (Neptun) at the beginning of the year, 557 took part in this survey, and following data cleansing and processing, 513 were considered in the results. Looking at the results of the practical, the most significant proportion of students, 142 of them have performed between 0-10%. A total of 260 students have achieved less than 20% performance and 434 people, which is nearly 85% of students have accomplished less than 40%. Compared to the results from the self-evaluation questionnaire it is very poignant that the actual scores differ quite significantly (in both directions) from the perceived knowledge of the students.

The way in which Aralia López relates to women and men involved a constant weaving of interpretations and proposing utopias in order to understand that a new personal and collective subjectivity is created by narrative and poetry. Aralia, a poet and an indispensable voice of Latin American feminist literary criticism, cultivated the friendship between women and the expression of feminine difference. Her work and way of life questioned the masculine patriarchal hegemony and casted serious doubts on traditional ideas and practices harmful to freedom.
