Authors: Nizeyimana Theoneste , Rugwizangoga Belson , Manirakiza Felix , Laga Alvaro C
Published: November 2021

Introduction: Helicobacter pylori (H. pylori) infection is the major cause of gastroduodenal diseases in populations of different ages.We conducted aretrospective studyusing archived tissue samples to determine the prevalence of H. pylori infection among patients diagnosed with gastritis and gastric adenocarcinoma by histopathology cases in one hospital in Rwanda. Materials and methods: Cases of chronic gastritis and gastric adenocarcinoma histologically diagnosed in a tertiary hospital in Rwanda over the period of 2016-2018 were studied for the presence of H. pylori using immunohistochemistry. Diagnosis of positive cases considered immunoreactivity as well as bacterial morphology, including spiral, rod-shaped, angulated and coccoid forms. Results: Three hundred and seven cases were included in this study; chronic gastritis and gastric adenocarcinoma representing 39% and 61%, respectively. The overall frequency of H. pylori infection was 77.5% (80% among chronic gastritis cases versus 76% among gastric adenocarcinoma cases). Prevalence of H. pylori infection in chronic gastritis and adenocarcinoma did not significantly associate with age and sex. Conclusion: The prevalence of H. pylori was high among chronic gastritis and gastric adenocarcinoma cases in Rwanda. Pathologists should investigate the presence of H. pylori in gastric biopsies. Our data shows immunohistochemistry method is feasible and adequate to facilitate detection of H. pylori, which may guide timely treatment.

Consideraciones críticas del fenómeno delirante inicial en el Método Paranoico Crítico de Salvador Dalí y el edificio CCTV de Rem Koolhaas
Authors: Ventura Blanch Ferran
Published: November 2021

El objetivo de este artículo es demostrar la vigencia del Método Paranoico crítico de Salvador Dalí en su aplicación a la interpretación y análisis del arte y la arquitectura, que el artista definió en su obra El mito trágico de «El ángelus» de Millet. Para ello se aplicará a la interpretación de la arquitectura de Rem Koolhaas, y en concreto a su edificio de la televisión China, el CCTV en Beijing. Se trabaja en convivencia con el plano imaginario y el plano más analítico siguiendo distintos caminos.
El fenómeno delirante inicial es el instante en que aparece por primera vez, de forma violenta, la imagen obsesiva, sobre la que se aplica el método paranoico crítico. Aquí el fenómeno delirante inicial es el acontecimiento del incendio del TVCC en Beijing producido en 2009. Desde que se manifiesta el mismo, la imagen real queda anclada al fenómeno delirante de forma instantánea.

La variedad de los ideales orientales: una relectura de la unidad de Asia en la obra de Okakura Kakuzō desde la perspectiva india
Authors: Román Aliste Sergio
Published: November 2021

Este estudio propone nuevos matices en la interpretación de la obra de Okakura Kakuzō The Ideals of the East (1903) a partir de fuentes teóricas bengalíes ligadas a la enseñanza artística. La interacción de Okakura Kakuzō con las élites culturales de Calcuta propició no solo la redacción de ese libro, sino también la puesta en marcha de un hermanamiento cultural de gran interés para el estudio de la modernidad artística en Asia. Este artículo descompone esa unidad ideológica de Asia propuesta por Okakura en interacción con los teóricos bengalíes con la intención de exponer las principales fuentes teóricas occidentales utilizadas en la construcción del ideal unitario asiático. La finalidad de este artículo es aportar claves ya consolidadas en la teoría artística anticolonial india para la lectura del texto de Okakura en una clave más abierta.
Characterization of Cr(III) interaction with kaolinite – Effect of the presence of Cr(VI)
Authors: Bounab Nourhane Amani , Boukhalfa Chahrazed , Reinert Laurence , Duclaux Laurent
Published: November 2021

In the present study, experiments were performed to characterize the effectiveness of kaolinite in Cr(III) removal from water in the absence and in the presence of Cr(VI). The results of batch experiments, show that the efficiency of Cr(III) removal by kaolinite increases with the increase of pH and temperature in both cases. The effect of the presence of Cr(VI) on the adsorption of Cr(III) by kaolinite depends on the solution pH and on the concentrations of the two ions. Whatever the system, the removal kinetic of Cr(III) is well described by the pseudo-second order model. Spectroscopic analyses reveal that Cr(III) interaction with kaolinite is mainly electrostatic.

Published: November 2021

The oxidative stress is one of the known and discussed culprits for development and progression of the disturbances in Metabolic syndrome (MetS). In our study, we are investigating the effects of antioxidant additives as additional treatment and prophylaxis in a model of MetS.

We are using a fructose-induced metabolic syndrome rat model to examine the effects of antioxidant preparation ZellSchutz. Four experimental groups were formed using male Wistar rats (n = 60). The control group received standard rat chow, the other groups received either ZellSchutz (Z), fructose (F), or fructose and ZellSchutz (ZF).

Our results showed an unexpected increase in the RBC indices in rats with dual treatment. There was a significant increase in hemoglobin concentration, MCHC, and MCV in those animals (p<0.001).

The preliminary data shows the important role of antioxidants as supplementary therapy in metabolic syndrome. Further investigations will be carried on to reveal the molecular mechanisms of the observed changes.
Allergenic potential of Platanus L. species in urban environment
Authors: Tsvetanova Rusana
Published: November 2021

The species of the genus Platanus L. are widely used in urban green infrastructure in Bulgaria and abroad, but are proven to be a serious source of allergen pollen emissions. The number of people, affected by pollinosis, is increasing every year and this affects the world economy and health of the population in a high level. The pollen of the plane tree is light, very small and spreads anemophilically. This is one of the genera that produce the largest amount of pollen per inflorescence. This makes Platanus a tree of a high allergy potential that has the tendence to get higher in time, because of its increasing use in urban green spaces. The aim of this study is to collect data for allergy potential of the three species of plane tree in some of the European countries, where the allergy is a significant problem, and to compare the sensitization of patients to its pollen in Bulgaria.

Published: November 2021

Rhodope Tourist Region is one of the most attractive tourist regions in Bulgaria and one of the few that stand out with almost uniform year-round development of tourist activities. The outlines of the tourist area largely coincide with the outlines of the mountain of the same name. This fact predetermines the exceptional richness and diversity of natural tourist resources. Here are the largest coniferous forests in the country, some of the largest dams, the largest number of caves used for tourist purposes, many mineral springs, bizarre rock formations, etc. The relatively well-preserved natural environment is a prerequisite for the presence of extremely high biodiversity, as well as a large number of protected areas. The region is specialized in mountain tourism, incl. ski tourism and hiking. In connection with the available natural tourist resources, the tourism product is increasingly enriched with various specialized types of tourism, incl. balneotherapy tourism, ecotourism, rural tourism, etc. In connection with the increasingly intensive tourist load, the problem of protecting the natural tourist resources from the growing anthropogenic pressure, as well as the prospects for sustainable development of the tourist industry in the region are becoming especially relevant. The aim of the present paper is to valorize the natural tourist resources of the Rhodope tourist region and to give guidelines for their sustainable use.
Degrees of Freedom: Is Good Philosophy Bad Science?
Authors: Williamson Timothy
Published: November 2021

The lecture starts by considering analytic philosophy as a tradition, and its global spread over recent years, of which Disputatio’s success is itself evidence. The costs and benefits of the role of English as the international language of analytic philosophy are briefly assessed. The spread of analytic philosophy is welcomed as the best hope for scientific philosophy, in a sense of ‘science’ on which mathematics, history, and philosophy can all count as sciences, though not as natural sciences. Arguably, experimental philosophy provides no plausible alternative methodology for philosophy, only a way of psychologizing it. However, it serves a useful purpose by highlighting the inadequacy of current methods for detecting errors in judgments on possible cases, which may result from reliance on possibly universal but imperfectly reliable cognitive heuristics. The problem is exacerbated by analytic philosophers’ tendency to regard increased flexibility in a theoretical framework as progress, where natural scientists would treat it as methodologically vicious profligacy with degrees of freedom. The result is a familiar type of bad science, overfitting theory to uncritically accepted data. The recent ‘hyperintensional revolution’ may be an example of such overfitting, it is suggested. The lecture ends with a call for a more miserly attitude to degrees of freedom.
Agent Causation Is Not Prior to Event Causation
Authors: Wong Soo Lam
Published: November 2021

My aim in this paper is to argue against the claim that agent causation is more fundamental than event causation. To accomplish this aim, I shall first briefly discuss the motivation behind agent causation. Second, I shall highlight the differences between agent causation and event causation. Third, I shall begin briefly with the weaker claim held by Timothy O’Connor and Randolph Clarke that there is no good reason to believe that event causation is more fundamental than agent causation. Fourth, I shall discuss the stronger claim held by E. J. Lowe that agent causation is more fundamental than event causation, and raise objections against the various arguments Lowe advances for the stronger claim. To the extent that my objections against Lowe’s stronger claim succeed, they raise questions for O’Connor’s and Clarke’s weaker claim.
External Debt, External Reserves, Debt Service Costs and Economic Growth: Implications for the Nigerian Transport Sector
Authors: Osadume Richard C. , Ovuokeroye Edih University
Published: November 2021

The objective of the study presented in this article is to examine the relationship between external debt (EXDT), external reserves (EXRS), total debt service costs (TDS) and Nigeria’s economic growth (RGDP) and how these variables impact on the Nigerian transport economy employing profligacy theory. The study used secondary data for Nigeria for the period 1979 to 2019 obtained from the International Debt Office (WBG). The econometric techniques used include OLS, Granger causality and Engle-Granger cointegration at a 0.05 confidence level. The results show that EXDT has a statistically significant negative relationship with EXRS, with no statistically significant relationship existing with RGDP and TDS in the short term. All the variables showed significant cointegration over the long term, with the conclusion that the relationship between EXRS and EXDT is negatively significant in the short term, while the other variables are insignificant. The recommendations of the study include, that the government and monetary authorities should endeavour to reduce the creation of foreign debt for nonreproductive projects in key sectors due to its adverse effect on external reserves, and instead pursue aid, grants and domestic long-term loan options necessary for effective growth of the transport and other key sectors of the economy.

Authors: But-Hadzic Jasna , Boltezar Anja Meden , Skerl Tina , Zadnik Vesna , Velenik Vaneja
Published: November 2021

Background

We conducted a phase II study to investigate the feasibility and safety of preoperative radiochemo-therapy experimental fractionation, using intensity-modulated radiation therapy with simultaneous integrated boost (IMRT SIB) to shorten the overall treatment time without dose escalation in intermediate/locally advanced rectal cancer with the aim to improving treatment outcome.

Patients and methods

A total of 51 patients with operable stage II–III rectal carcinoma were included between January 2014 and January 2015. Fifty patients completed preoperative IMRT treatment with an elective dose of 41.8 Gy and simultaneously delivered 46.2 Gy to T2/T3 and 48.4 Gy to T4 tumour in 22 fractions, with concomitant capecitabine (825 mg/m2/12 h, including at weekends). Median follow-up was 70 months (range 11–80 m).

Results

Forty-seven patients completed treatment per protocol. Acute toxicity occurred in 2 (4%) patients. R0 resection was achieved in all but 1 and pathologic complete response (pCR) in 12 (25.5%) patients who had 5-year overall survival (OS), disease-free survival (DFS) and local control (LC) of 91.7%, 100% and 100%, respectively. The intention-to-treat analysis showed that the type of surgery significantly moderated OS and DFS, while total downstaging and pN were predictive for DFS only. For treatment per protocol 5-year OS, DFS and LC were 80.9% (95% confidence interval [CI] 69.7–92.1), 77.1% (95% CI 65.1–89.1) and 95.2% (95% CI 88.7–100), respectively. The proportion of patients with severe late (CTCAE G ≥ 3) gastrointestinal, urinary and sexual toxicity was 15%, 2% and 8% respectively, with one reported secondary carcinoma.

Conclusions

Preoperative IMRT-SIB without dose escalation was well tolerated, with a low acute toxicity profile, we achieved a high rate of pCR and showed encouraging 5-year OS, DFS and LC.

Published: November 2021

Background

Chemoradiotherapy (ChT-RT) followed by 12-month durvalumab is the new standard treatment for unresectable stage III non-small cell lung cancer. Survival data for patients from everyday routine clinical practice is scarce, as well as potential impact on treatment efficacy of sequential or concomitant chemotherapy and the usage of gemcitabine.

Patients and methods

We retrospectively analysed unresectable stage III NSCLC patients who were treated with durvalumab after radical concurrent or sequential chemotherapy (ChT) from December 2017 and completed treatment until December 2020. We assessed progression free survival (PFS), overall survival (OS) and toxicity regarding baseline characteristic of patients.

Results

Eighty-five patients with median age of 63 years of which 70.6% were male, 56.5% in stage IIIB and 58.8% with squamous cell carcinoma, were included in the analysis. Thirty-one patients received sequential ChT only, 51 patients received induction and concurrent ChT and 3 patients received concurrent ChT only. Seventy-nine patients (92.9%) received gemcitabine and cisplatin as induction chemotherapy and switched to etoposide and cisplatin during concurrent treatment with radiotherapy (RT). Patients started durvalumab after a median of 57 days (range 12–99 days) from the end of the RT and were treated with the median of 10.8 (range 0.5–12 months) months. Forty-one patients (48.2%) completed treatment with planned 12-month therapy, 25 patients (29.4%) completed treatment early due to the toxicity and 16 patients (18.8%) due to the disease progression. Median PFS was 22.0 months, 12- and estimated 24-month PFS were 71% (95% CI: 61.2–80.8%) and 45.8% (95% CI: 32.7–58.9%). With the median follow-up time of 23 months (range 2–35 months), median OS has not been reached. Twelve- and estimated 24-month OS were 86.7% (95% CI: 79.5–93.9%) and 68.6% (95% CI: 57.2–79.9%).

Conclusions

Our survival data are comparable with published research as well as with recently published real-world reports. Additionally, the regimen with gemcitabine and platinum-based chemotherapy as induction treatment was efficient and well tolerated.
Immunohistochemical Analysis of the Expression of the Glycodelin Cytokine in Endometrial Tissue and the Endometrial Polyp, Before and After Hysteroscopy, in Infertile Female Patients
Authors: Dević Aleksandar , Dević Ana , Šorak Marija , Zajić Goran , Mitrović Slobodanka
Published: November 2021

An endometrial polyp is most commonly a benign, localized proliferation of the glands and the endometrial stroma, covered with epithelium and protruding above the level of the mucosa. These polyps are most often diagnosed during investigation into the causes of irregular menstrual bleeding or infertility. It is produced in the highest concentration during the secretory phase of the endometrial cycle. The level of glycodelin reaches its peak 12 days after ovulation. The aim of this paper was to determine the changes in the immunohistochemical expression of glycodelin at the level of the endometrium and in the tissue of the polyp, before and after hysteroscopic polypectomy, in infertile female patients with an endometrial polyp, and in the endometrial tissue of female patients without an endometrial polyp. The study included 82 infertile female patients. The infertile patients were divided into two groups. The first was the experimental group which included 56 infertile female patients who had an endometrial polyp. The second group was the control group, composed of 26 infertile female patients who did not have an endometrial polyp. The results obtained primarily indicate the existence of changes in the immunohistochemical expression of the cytokine glycodelin in the female patients from both the experimental and the control group, not only prior to but also after hysteroscopy. A larger number of patients who have an endometrial polyp show a lack of glycodelin expression, more pronouncedly so in the bioptate of the endometrium than in the endometrial polyp.

Appendiceal mucoceles represent neoplastic and non-neoplastic, dilatated, mucus filled appendix vermiformix. Appendectomy is obligatory due to a possible malignancy. It is crucially important to avoid rupturing of the mucocele because it can result in pseudomyxoma peritonei, with high morbidity and mortality. We presented a 52-year-old man with pain and palpable mass in the lower right quadrant of the abdomen. The mucocele was removed without a rupture, and the patient was discharged from the surgical department one day after the surgery without a complication. The resection must be done very carefully, because the rupture of a mucocele can cause pseudomyxoma peritonei, a very dangerous and often lethal condition. Due to the concern of rupture, we performed the classical resection through laparotomy. It is very important, especially for young, inexperienced surgeons to be aware of this rare diagnosis and perform a surgical intervention according to the guidelines of good clinical practice.

Authors: Perrin Antoine
Published: November 2021

Alternative agri-food initiatives have the ambition to build an alternative to the market and industrialization, but these initiatives are nevertheless accused of depoliticization. Scarcely prone to subversion, allegedly they would only address the upper classes and fail to create a movement. An ethnographic survey among these initiatives in a city in eastern France, provides answers to these questions, showing a different definition of the economy re-embedded in politics and territory.
The Unprecedented Lockdown: The consequences of job loss
Authors: Rughoobur-Seetah Soujata
Published: November 2021

Various studies have analyzed employees’ perceptions with regards to voluntary turnover and very few studies have attempted to identify and assess the consequences of involuntary turnover on the employees. Thus, this study attempts at analyzing the consequences of any potential involuntary turnover on employees that can take place as a response to the economic crisis that will occur with the COVID-19 pandemic. Factors like role overload, job stress, occupational burnout and Work Family Conflict (WFC) has been identified as the resulting effects of any job losses. Significant and positive relationship was recorded among variables and the relationship between involuntary turnover and WFC and between job stress and WFC were rejected. The Conservation of Resources theory (COR) and the Spillover and Crossover theory were used to better understand the complexities of the matter. The limitations and future work prospects have also been discussed.

Do Exchange Rates Fluctuations Influence Gold Price in G7 Countries? New Insights from a Nonparametric Causality-in-Quantiles Test
Authors: Raza Syed Ali , Shah Nida , Ali Muhammad , Shahbaz Muhammad
Published: November 2021

In the recent era, gold is considered an essential investment source, a source of hedging inflation, and a medium of monetary exchange. The gold and exchange rate nexus become prominent after events like sovereign debt crisis, subprime mortgage crisis, low-interest rate problem, and global financial market solvency. These events attract the attention of researchers and academician for investigating the dynamics of the relationship between gold and exchange rates, and the majority of the studies discusses the linear dynamics, but the non-linear dynamics are ignored. Therefore, the current research investigates the non-linear dynamics of gold price and exchange rate relationship in G7 countries using the new technique named the nonparametric causality approach. This study uses monthly data from the years 1995(January)-2017 (March). The empirical results show that exchange rate return causes gold prices in four out of G7, especially at the low tails. This study also gives valuable insights for monetary policymakers, gold exporter’s international portfolio managers, and hedge fund managers.
Analytical approach to the influence of motivation on the dynamics of heterogeneous employees and expected average costs of efficient work
Authors: Talajić Mirko , Vrankić Ilko , Kopal Robert
Published: November 2021

Motivating employees with different characteristics has a significant effect on company performance. This paper models the relationship between employer and heterogeneous employees working in pairs as a principal-agent problem. Every worker can encounter moral hazard with regard to the stimulation of the employer and the efficient work of co-workers. Employee behavior describes a reaction function based on which the equilibrium of appropriate pairs of employees and their overall effective performance is described. The employer determines the optimal stimulation that minimizes the expected average cost of effective work for each individual group of employees. The total expected average cost of efficient work of the entire company in the short run depends on the distribution of employees with different characteristics. How the attitude of employees towards work in the long run changes is described by replicative dynamics and shows that the stability of the employee population is achieved in two cases where the long-run total expected average cost of efficient work is differentiated by approximately eight percent. This paper describes a new conceptual framework for quantitative analysis of the effects of motivation on the short and long run financial results of an enterprise.

This study examined farmers’ level of use of climate change adaptation strategies across selected agro-ecological zones in Nigeria. Edo and Ondo States were selected for the study with three major agro-ecological zones. A multi-stage sampling procedure was used. The correlation analysis revealed a significant relationship between year of education and level of use of adaptation strategies (r = 0.15, P = 0.02). The result of Analysis of Variance (ANOVA) revealed that significant differences existed in most of the adaptation strategies employed except planting different varieties (F = 1.672, P = 0.190), intercropping (F = 0.646, P = 0.525), crop rotation (F = 2.436, P = 0.090) and migration to different sites (F = 0.661, P = 0.517). The study recommended that the issue of climate change should not be taken lightly by all stakeholders as its effect differs among various agro-ecological zones.

It is known that plants have been used by humans for a very long time in the treatment of diseases. A wide variety of plant species grown in different regions have been very successful in the treatment of many diseases. In this study, Echium italicum L. plant collected from different regions was used as material. The plant was extracted with ethanol in a soxhlet device. Then, antioxidant and oxidant levels of the plant extract were determined using Rel Assay kits. As a result of the analysis, the TAS values of the plant were determined 5.442±0.240 (Gaziantep), 4.896±0.081 (Hakkari) and 6.056±0.139 (Mersin), TOS values were 21.372±0.747 (Gaziantep), 12.255±0.341 (Hakkari) and 19.107±0.438 (Mersin), OSI values were 0.395±0.027 (Gaziantep), 0.250±0.005 (Hakkari), and 0.316±0.005 (Mersin). It was observed that antioxidant and oxidant values changed as the regions where the plant was collected changed. In addition, it was determined that E. italicum could be a natural antioxidant source.

Published: November 2021

This study was conducted to determine the effect of zinc on the productive performances, carcass yield and blood profiles of broilers. Experiment was done for a period of 35 days with a number of 60, day old broiler chicks. Birds were divided into four dietary treatment groups with 3 replications each having 5 birds per replication. The dietary treatment groups were; T0 (basal diet; no zinc), T1 (basal diet + 50 mg zinc/kg feed), T2 (basal diet + 100 mg zinc/kg feed), T3 (basal diet + 150 mg zinc/kg feed). Results revealed that body weight and body weight gain were significantly increased in the zinc supplemented group compared to the control group. Higher feed intake and better FE were also observed in the zinc supplemented group than the control group and the best performance was observed in the group fed 150mg zinc/kg feed (T3). Carcass yield was significantly higher in the groups fed dietary zinc. Net profit was slightly higher in the T3 group but not significantly (P.0.05) differed with the control group. However, T1 and T2 showed less profit even than the control group. Blood profile of the experimental birds including Hb, PCV, and ESR did not significantly differ among the groups. The results indicate that the addition of zinc in the broiler diet improves productive performances, carcass yield and increases net profit without affecting the health status of broiler. So, zinc can be used as an effective and useful micronutrient to improve the performances of broiler.

Lactic acid bacteria play an important role in the fermentation of biological feed. In this experiment, Lactobacillus plantarum, Lactobacillus acidophilus, Bifidobacterium longum, Lactobacillus casei and Lactobacillus rhamnosus were used to ferment corn stalk by single and mixed bacteria. The changes of Lactobacillus flora during fermentation were analyzed by fluorescence quantitative PCR. The results showed that the maximum number of lactic acid bacteria appeared on the 7th day of mixed fermentation, and the total bacteria content could be significantly increased by adding five kinds of lactic acid bacteria at the same time, and the number of each bacteria in mixed fermentation was close to that measured by single fermentation, which indicated that these five kinds of lactic acid bacteria could cooperate during fermentation and help to improve the quality of stalk fermented feed.

In this paper, Epilobium angustifolium L. in Turkey was investigated for total phenolics, flavonoids, and anthocyanin amounts. Furthermore, the ethanol extract of the leafs was evaluated for antioxidant activities as ABTS, hydroxyl radical scavenging, superoxide radical scavenging, power of reduction, and bleaching of beta-carotene. The total phenolic and flavonoid contents of the ethanolic extract were found to be 468,11± 1,53 micrograms of pyrocatechol per milligram of the extract and 103,05 ± 2,36 µg catechin per milligram of the extract, respectively. As the extract concentration increased, the amount of anthocyanins showed a decrease (17.92±8.08 and 13.56±8.22 for the 1 mg/mL and 2 mg/mL concentrations, respectively). In the β-carotene bleaching test, higher activity was observed than BHA ( 1.540±0.053 and 1, respectively). The results of the reduction power, hydroxyl radical scavenging, and ABTS tests gave either very close values or higher than the standards chosen. Superoxide radical scavenging activity gave a lower value than the Trolox selected as standard. Antioxidant activity of ethanol extract was found to be 94.22±0.05958 (ABTS), 78.77±0.84099 (hydroxyl radical scavenging) and 47.86±0.03915 (superoxide radical scavenging). The experimental data indicate that Turkey Epilobium angustifolium L. ethanol extract can be used pharmacologically.

During the fermentation of corn stalk bio-feed, the quantity of bacteria in corn stalk bio-feed was counted by fluorescence quantitative PCR and plate colony counting respectively. The comparative analysis of these studies was used to explore the feasibility of fluorescence quantification methods and changes in microbiota during fermentation. The results showed that the standard deviation of fluorescence quantitative method was smaller than that of plate method, but the trend was similar. The biomass of Bacillus subtilis, Lactobacillus plantarum and Saccharomyces cerevisiae reached their maximum on the third, fifth and fifth day respectively, and then decreased gradually and maintained at a certain level. The experiment showed that the fluorescence quantitative PCR method can accurately quantify the number of bacteria in corn stalk bio-feed, and it is a better method to quantitatively detect the dynamic changes of different kinds of bacteria in corn stalk bio-feed.

The aim of this comparative study was to obtain a model for production of inulinase and invertase by species Saccharomyces, Candida and Hansenula, strains from culture collection of INCDCF-ICCF, using submerged fermentation in a medium containing inulin as source of C. This model explained the data variation and the actual relationships between the parameters and responses. The dry biomass content as well as the production of inulinase and invertase in the bioprocess medium was influenced by inulin concentration and microelement composition. The main parameters for bioprocesses were: inoculum size 2% (v/v), pH 6, temperature 280 C and 220 rpm agitation speed. Following comparative study for production of extracellular inulinase (exo and endo inulinase) and invertase were obtained for Candida arborea the best results, invertase production having significantly higher concentrations than inulinase (35.92 U/mL invertase activity vs. 8.01 U/mL inulinase activity), on M5 medium. These results could be useful for industrial applications such as food industry, pharmaceutical.

Los resultados de este artículo muestran que en 2003 la industria representa un 3,9% del PIBpm y un 7,8% del empleo. Se observa una alta concentración de la industria tanto desde el punto de vista regional como sectorial.
El capital humano como determinante del consumo cultural
Authors: Ateca Amestoy Victoria María
Published: November 2021

En este trabajo discutimos la relevancia del capital humano para explicar diferencias en el consumo cultural y estimamos el efecto que la disponibilidad de este recurso personal tiene en las diferencias en la asistencia a actividades culturales. Utilizamos para ello datos de la Encuesta de Participación Pública en la Artes del año 2002 para Estados Unidos. Estimamos ecuaciones de participación para las 7 actividades de referencia definidas por el National Endowment for the Arts para explicar el número de veces que un individuo ha asistido a lo largo de un año a esas actividades. El concepto de capital cultural que utilizamos es el de un recurso personal que aumenta la productividad de los individuos que satisfacen sus necesidades culturales a través de consumo de bienes culturales. Explicamos la dotación de este tipo de capital cultural que tiene cada individuo a través de la educación formal de sus padres, de la educación general que han recibido y de diferentes tipos de educación cultural específica. Los modelos de participación son estimados usando modelos de regresión para datos de recuento, de todos ellos, seleccionamos un modelo binomial negativo con inflación de ceros.
A Contingent Ranking Study on the Preferences of Tourists across Seasons
Authors: Cuccia Tiziana
Published: November 2021

This paper presents the results of a contingent ranking study carried out on a sample of tourists visiting the province of Ragusa (in South-Eastern Sicily, Italy), known for both its baroque heritage and its sea coasts. I focus only on two attributes of tourism products, namely the accommodation facilities (which appear to have a large importance for tourists’ choice, according to similar previous analyses) and local attractions (sea and coasts, cultural and natural heritage endowments, performing-arts and entertainment, local food and wine products). I  evaluate whether and how the weight attached by tourists to the attributes and their levels change across seasons.

La política de la competencia versus la política social y de empleo en la UE
Authors: Rodríguez Miguez José Antonio
Published: November 2021

El objeto del presente trabajo, dentro de un número monográfico dedicado a la Política Social Comunitaria, es ofrecer una visión diferente de la que se ha asignado a las relaciones entre la Política Social y de Empleo y la de la Competencia, que tradicionalmente han sido vistas como antagónicas. Frente a esta consideración, percibida por muchos operadores económicos, trataremos de poner en evidencia la complementariedad de ambas, pues la Política de la Competencia, tiene una fundamental dimensión social en la medida en que promueve la eficiencia de las empresas y la mejor asignación de recursos públicos, estimulando el progreso económico y el bienestar de trabajadores y consumidores.

Authors: Albert López-Ibor Rocío , Escot Mangas Lorenzo , Fernández Cornejo José Andrés
Published: November 2021

En este trabajo se estudia en qué medida las estudiantes universitarias contemplan para el futuro la posibilidad de ralentizar sus carreras profesionales por razones de conciliación en mayor medida que los estudiantes varones. Para ello se ha realizado una encuesta a estudiantes universitarios en la que se intenta captar cuáles son sus preferencias en cuanto a estilos de vida laboral-familiar, sus aspiraciones profesionales y sus actitudes de género. A partir de aquí se procede a estimar el porcentaje de estudiantes encuestadas que tienen un grado de aspiración profesional alto (que resulta ser significativamente inferior al correspondiente a los estudiantes varones), y se analizan algunos factores personales y culturales que pueden estar relacionados con el hecho de ser una estudiante con esa característica.
The Importance of Trend-Cycle Analysis for National Statistics Institutes
Authors: Mclaren Craig H. , Zhang Xichuan (Mark)
Published: November 2021

Seasonal adjustment is a widely applied statistical method. National Statistics Institutes around the world apply seasonal adjustment methods, such as X-12-ARIMA or TRAMO-SEATS, on a regular basis to help users interpret movements in the time series and aid in decision making. The seasonal adjustment process decomposes the original time series into three main components: a trend-cycle, seasonal and irregular. By definition the seasonally adjusted estimates still contain a degree of volatility as they are just a combination of the trend-cycle and irregular. Typically, as an analytical product, the seasonally adjusted estimates are published alongside the time series of the original estimates. In most countries the trend-cycle estimates are not published. Some countries, such as Australia, regularly publish trend-cycle as additional analytical product alongside the original and seasonally adjusted estimates to inform users. This paper presents the case for the regular calculation and production of trend- cycle estimates at National Statistics Institutes to help inform and educate users about the longer term signals in the time series.
