Effect of Exports of Goods and Services and Energy Consumption in Italy`s Service Sector
Authors: Huseynli Bahman
Published: May 2023

The aim of this study is to examine the service sector in Italy, one of the Mediterranean countries, and the relationship between the energy consumption affecting this sector and the factors of export of goods and services. The data set used in the model tested by panel analysis method covers the years 1997-2021. When the values related to the analysis result are examined, it is understood that the model is generally significant at the 95% confidence level. The R2 coefficient, which is important in the model, is approximately 95%. Exports of goods and services, one of the explanatory variables in the model, were found to be significant in explaining the commercial service exports of this country. In other words, the 1% increase in Italy's exports of goods and services explains this country's exports of commercial services at the level of 86%. This relationship between variables has a positive meaning. The relationship between energy consumption and exports of commercial services was found to be significant at the 5% probability level. The relationship between these two variables is also positive. It was concluded that a 1% increase in energy consumption explains this country's commercial service exports by approximately 27%.

Published: May 2023

The National Institute of Science and Technology for Energy and Environment (INCT E&A) is a virtual network of scientific-institutional cooperation focused on research for energy sustainable use and environmental preservation. This article aimed to identify production and articulations of researchers affiliated to INCT E&A in biodiesel research in the period from 2009 to 2020, based on scientometric, and social and complex network analysis. Altogether 76 articles involving biodiesel theme were analysed and a network of 212 authors from 48 institutions with a high level of collaboration was identified. Network topological properties were calculated, making it possible to find central researchers and affirm that it presents the small world phenomenon. It was also possible to observe that scientific production by the researchers occurred especially between the years 2009 and 2014. After this period, biodiesel theme stopped attracting INCT E&A researcher’s attention, demobilizing a network at a moment when Brazil chose biofuels as a decarbonizing strategy for transport matrix through the National Biofuels Policy (RenovaBio).

Interessenkonflikte und illoyales Stimmverhalten Über die mangelhafte Beschlussfassung in Personengesellschaften
Authors: Blank Paula
Published: May 2023

The duty of loyalty in partnership law requires partnership members to actively and loyally participate in the decision-making process of the partnership. If the partners are facing conflicts of interest, disloyal voting may occur if the interest of the company is not adequately taken into account. The point at which the threshold of disloyalty is reached depends on the specific item of the resolution. Generally speaking, the interests of the partnership take precedence over the personal interests of the members in the case of partnership resolutions on management measures, whereas it is altogether more legitimate to pursue egoistic objectives when adopting fundamental resolutions that concern the members’ individual sphere.

Manure, which is a mixture of solid dung, urine, and (plant) food waste, plays a very important role as a food source for soil organisms. Due to the various benefits and high economic value of the gambas plant, numerous efforts have been made to increase productivity and suppress the growth of pathogens that can interfere with gambas growth, one of which is the use of biological agents. The biological agents commonly used are from the fungi group. Trichoderma harzianum is one type of fungi that can be used as a biological agent. This study used a factorial group design consisting of two factors, with a 4x3 factorial pattern and 3 replications. The factors studied included types of manure and doses of Trichoderma fertilizer, which consisted of 12 levels, namely K0= control (un-fertilizer), K1= Goat Manure (2 kg/plot), K2= Chicken Manure (2 kg/plot), K3= Cow Manure (2 kg/plot), while the Trichoderma Fertilizer Factor (M) consisted of 3 levels, namely M0= Control, M1= Trichoderma (5 g/plot), M2= Trichoderma (10 g/plot). The results showed that the application of manure and Trichoderma koningii fertilizer had a significant effect on plant height, number of leaves and fruit weight of the sample/plot, which indicates that the application of both types of fertilizers can increase the content of organic matter in the soil.

Melon (Cucumis melo L.) is one of the most popular fruit commodities in Indonesia, thanks to its sweet, wonderful flavor, as well as its high nutritional content and nutritional value. Consumer demand for melons is very high, both locally and internationally, although the sugar level of this particular melon is not too sweet. A melon (Cucumis melo L.) is a herbaceous annual plant that grows on vines and is a member of the cucumber family. This study aimed to determine the optimum concentration of cow urine for development (Cucumis melo L.). The experiment used a fully randomized design (CRD) with one factor, namely the concentration of 6-level bio urine, namely B0 = 0 percent bio urine, B1 = 10 percent bio urine, B2 = 20 percent bio urine, B3 = 30 percent bio urine, B4 = 40 percent bio urine, and B5: 50 percent bio urine from 100 ml/plant recommendation. The research findings indicated that application of bio-liquid organic fertilizer (POC) to cow urine may increase: plant length, stem diameter, number of male flowers, and number of female flowers with the best 10 percent POC bio-cow urine. Melon growing can produce 10 percent bio-liquid organic fertilizer (POC) from cow urine.

This article presents research findings on image construction as a strategy of resistance used by progressive community agencies to be responsive to the increasing marginalization of their service users in current times. The agencies project nuanced images in representing their work to service users, funders and stakeholders and community partner agencies. These nuanced images serve to demonstrate the multiple and complex identities of these agencies. The agencies have used this strategy successfully to reclaim their power with funders and use their power effectively in making their services responsive and relevant to the situations of service users. The article provides an interesting presentation on the dynamics of the use of this strategy by progressive community organizations.

The study evaluated the influence of breeds, physiological status and diets on biochemical parameters of West Africa Dwarf (WAD) and Sahel goats at the Teaching and Research farm of the Federal Polytechnic Bali, Taraba State.  A total of twenty-four does and their corresponding progenies of the two breeds were used for this study. Blood samples were collected from each animal to evaluate the biochemical parameters, which lasted for 12 calendar months. The animals were fed feeds components of Gmelina and cassava peel meal, Gmelina and cowpea husk, Ficus and cassava peal meal and, Ficus and cowpea husk as treatments (T1-T4 respectively).The parameters considered were, calcium, potassium, phosphorus, chlorine, creatinine, albumin, protein, alanine aminotransferase and aspartate aminotransferase. The data obtained was subjected to analysis of variance (ANOVA), using (Statistix, version 8.0, 2009) statistical package. The overall results of biochemical parameters by breed, physiological status and diet were 2.044, 103.88, 5.498, 139.84mmol/l, 3.415, 33.053mg/dl, 31.327mmol/l, 45.654g/dl, 8.500, 25.0iu/l and, 51.010g/dl, for Ca, Cl, K, Na, Urea, CRT, P04, ALB, ALT, AST, and TP respectively. Base on the present findings therefore, it is concluded that, Biochemical parameters are useful measures of physiological statuses are quite variable. The study has provided useful body of information/knowledge on the reproductive biology of the two goat breeds of the study area, which hitherto was not available. These indices should therefore be used with caution for any rigorous interpretation.

Fungal diseases are the major threat and limiting factor in the production of economic crops which causes a tremendous loss of yield annually. The aim of this study was to assess the major fungal pathogens associated with tomato and pepper with a view to identify their presence incidence and severity. Field assessment was conducted in five irrigation villages in Jama’are during the dry season. At each location, 50 plants were assessed in fields by counting number of infected crops observed in an “X” pattern across the fields. Infected portion of diseased samples were collected for microscopic identification of the pathogens. Pathogenicity test was carried out to confirm the ability of the isolated pathogens to produceypical symptoms of the disease on the healthy plants. Data obtained were subjected for analysis of variance (ANOVA) at 5% level of significance. The result of the study shows that tomato recorded the highest disease incidence and severity in Dako-dako and DogonJeji while pepper recorded the lowest disease incidence and severity at Digiza. A total of 16 different fungal pathogens were identified based on cultural morphology and microscopic identification on potato dextrose agar (PDA) at 25±2ºC. Pathogenicity test revealed that 13 fungal pathogens were highly pathogenic to tomato and pepper. Identified fungal pathogens are the main causal agent of diseases in the study area which cause substantial losses and damages to the economic crops. It is recommended that an integrated approach involving proper agronomic practices should be applied for sustainable yield production in the study area.
Calmness as a Quality of Teacher Presence and the Impact on Learning
Authors:   , Pelton Kiana
Published: May 2023

This study seeks to identify the conditions for calmness within an educator's life and its impact on educators and students. Research shows that mindfulness practices can be implemented in the classroom and help students focus (Riner & Tanase, 2014). According to Kane (2018), implementing different practices and strategies of mindfulness can help regulate the internal and external stresses that happen daily. Currently, there is a lack of existing research on what educators do to calm themselves outside of the school day and how those practices impact their relationship with the students, helping students feel calm during school. Specifically, this study seeks to determine what practices educators use to calm themselves, what calmness is to the educators, and how it impacts student learning. This mixed methods research with constructive and transformative worldviews explored the environmental practices of educators as it related to how they set the space for learning and creating the conditions for their own functional health. Six educational professionals who specialize in working with students with special needs completed surveys and participated in individual interviews. The school site where the educators work is a Title One school with a mostly low-socioeconomic student population. The educational professionals ranged from being in their first year to having worked in education for twenty-four years. The data illuminated three major findings. First, creating boundaries and recognizing that, ultimately, teaching is also just a job proved to be important in creating healthier states for teachers to maintain balance in their lives and creating space for self-care routines. Secondly, it was identified how significant the state a teacher maintains impacts the experience of students and the way teachers can show up for their diverse needs. This second finding was noted in the in vivo theme of “It’s a Snowball Effect.” Lastly, the role of support proved critical to the health and well-being of educators, and how feeling supported is essential, especially when stressed. The significance of this study points to the need for cultivating healthier environmental care to support educational professionals. This includes maintaining a quality of presence that best serves equitable and inclusive learning for students. When educators take care of themselves, the students will be calmer, creating a better learning atmosphere. When educators are not prepared for the day and are mentally exhausted, the school day will become hectic, and students will have a harder time learning.

A premenstruációs tünetek előfordulása nagyon gyakori a nők körében. Kevésbé kutatott terület a premenstruációs tünetek sportteljesítményre való hatása. A kutatás célja, hogy bemutassuk a premenstruációs tünetek előfordulását és hatását a sportteljesítményre, továbbá hogy megtaláljuk a választ arra a kérdésre, hogy a premenstruációs tüneteket észlelő jégkorongozók sportteljesítménye mutat-e különbséget a premenstruációs tüneteket nem észlelő sportolókhoz képest. A kiválasztott 12 versenyszintű, női jégkorongozó esetében meghatározásra került a menstruációs ciklus 4 fázisa: a korai follikuláris, a késő follikuláris, a középluteális fázis és a késő luteális (premenstruációs) fázis. A négy fázisban került sor a robbanékony erő és maximális izometriás izomerő mérésére. Szignifikáns különbséget találtunk a premenstruációs tüneteket nem tapasztaló alanyok különböző menstruációs fázisainak robbanékony ereje között. Az erőkifejtés és a robbanékony erő értékei a különböző csoportokban, illetve a csoporton belül változó tendenciát mutatnak. A kutatás eredményei alapján további vizsgálatokra van szükség a ciklus változásainak mélyebb megértéséhez.
