Authors: Valverde  Moya José , Varela Alexander , Montero Álvaro
Published: May 2023

Dado que muchas de las especies utilizadas para fines acuícolas son exóticas y sin considerar el grado de alteración que pueden causar en los ecosistemas y especies nativas, este estudio se llevó a cabo con el objetivo de introducir una especie nativa como Dormitator latifrons a los sistemas tradicionales de acuicultura en estanques. Los sistemas de policultivo con especies de mayor valor comercial han proporcionado una estrategia útil para el desarrollo de la acuicultura sostenible de peces nativos. Por esta razón, este estudio evaluó el rendimiento de producción y el crecimiento de D. latifrons en policultivo con tilapia roja (Oreochromis spp.) y langostino (Macrobrachium rosenbergii) en estanques de producción en Costa Rica. Juveniles con pesos iniciales de 36,5 g ± 7,7 para D. latifrons, 14,2 g ± 7,5 para tilapias y 13,1 g ± 8,4 para langostinos, fueron utilizados durante la fase experimental realizada en 2 estanques divididos en 3 secciones de 24 m2. Los organismos fueron aleatoriamente distribuidos mediante un tratamiento con 3 réplicas en policultivo compuesto por 42 D. latifrons (1,75 Ind./m2), 34 tilapias (1,42  Ind./m2) y 27 langostinos (1,12 Ind./m2), mientras que en el control se utilizó, por triplicado, 30 D. latifrons en monocultivo a una densidad de siembra de 1,25 Ind./m2. El policultivo de D. latifrons con tilapias y langostinos tuvo un efecto perjudicial en el crecimiento de los peces lo que demuestra una interacción negativa entre ellos, existiendo competencia por espacio y alimento. Dormitator latifrons puede adaptarse a la alimentación artificial y competir con otras especies como las tilapias en la etapa juvenil, pero no muestra el mismo comportamiento conforme crece, lo cual podría explicar la caída del crecimiento en las últimas 9 semanas en policultivo con mayor cantidad de individuos en el estanque. La productividad del policultivo, en términos de la biomasa final alcanzada, fue considerablemente más alta que en monocultivo al sembrarse y cosecharse mayor cantidad de organismos.

Published: May 2023

Este estudio reporta la síntesis y caracterización espectroscópica de vidrios PbO-BiO2- Ga2O3 con nanopartículas de plata e iones de Nd3, y la absorción característica del Ftalato de Potasio (sustancia patrón cuyo consumo de oxigeno se relaciona con la del agua para determinar el nivel de materia orgánica), con la finalidad de crear una técnica  óptica que determine los niveles de materia orgánica presente en el agua. Utilizando Microscopia Electrónica de Transmisión (TEM) y espectroscopia de absorción y de Luminiscencia, se analiza la influencia de las partículas de plata sobre la emisión de iones Nd3 correspondiente a la transición 4F77’2 →4l9/2… Se identificaron partículas esféricas con diámetros entre 2 y 20 nm y un aumento de la luminiscencia de esta transición en muestras dopadas con partículas de plata. El aumento de la emisión de los iones Nd3 en las muestras vítreas que contienen las nanopartículas, se debe probablemente al aumento del campo eléctrico local y a la transferencia de energía de las partículas pequeñas (menores de 10 nm) a los iones. La caracterización óptica del Ftalato de potasio se hizo mediante espectroscopia de absorción, la cual presentó una banda ancha en el ultravioleta donde el ion también absorbe. Estas absorciones sumadas con la emisión más representativa de los iones son la base para la creación de la técnica óptica, ya que, así como las nanopartículas pueden disminuir y/o aumentar      tanto las emisiones como las absorciones de los iones de tierras raras, la materia orgánica (a través del Ftalato de Potasio) lo podría hacer y la cuantificación de esta influencia mediría el nivel del material orgánico presente en el agua.

Published: May 2023

Hypodontia is a type of dental anomaly that can affect dogs, characterized by the congenital absence of up to six deciduous or permanent teeth. According to reports in the literature, the absence of a dental element is an incidental finding and the absence of the first premolar teeth is observed more frequently. It is believed that there is a genetic component and viral factors that predispose to the non-development of dental elements. However, an interruption in the development of these same dental elements can cause tooth failure. It is not possible to discern whether there is a dental element or not just through the macroscopic examination of the oral cavity. In this sense, it is necessary to carry out an intraoral radiographic examination for diagnostic elucidation, which will lead to an appropriate treatment. According to the literature, non-eruption of teeth can generate a dentigerous cyst, whose treatment is based on the extraction of any remaining tooth tissue.

Returnable packaging in e-commerce from socio-economic perspective – research results
Authors: Górniak Joanna , Bukowska-Piestrzyńska Agnieszka
Published: May 2023

Growth in online sales results in an increase in the number of containers remaining in economic circulation, causing both economic (increased costs of container production, storage and disposal) and environmental effects. One way to reduce the scale of this problem would be to introduce reusable packaging, which enterprises could use as part of their e-commerce solutions. The question remains, however, whether the customers are ready for this. What is their opinion on implementing such a solution? Would they be willing to pay a deposit for using such containers? This paper aims to suggest individual returnable packaging solutions that can be used in e-commerce to manifest corporate social responsibility and reflect customer attitudes towards them. The paper is empirical, with the empirical part presenting the results of the author's study.

Authors: Nowacki Marek , Niezgoda Agnieszka
Published: May 2023

The article aims to analyse and compare experiences gained by tourists visiting three national parks in Poland. The authors focused on the following questions: What are people's experiences visiting national parks in Poland? Do the natural assets of the national parks affect visitors' unique experiences, or are environmentally valuable areas not crucial for their experiences? The authors used mixed quantitative (text mining, correspondence analysis) and qualitative (content analysis) methods. The data for analysis were opinions written by TripAdvisor users. Reviews on TripAdvisor indicate that the most important experiences for tourists in the National Parks studied were Nature appreciation and Physical activity. The other groups of experiences reflected in the reviews were: Aesthetic, Connection, Tension and Excitement. This confirms that nature is the most important feature of national parks for tourists, but it also indicates a trend to maintain good health and the desire to regenerate physical strength in areas of natural beauty.
Changes in the Polish market for agricultural organic products
Authors: Kociszewski Karol , Graczyk Andrzej , Sobocińska Magdalena , Krupowicz Joanna , Mazurek-Łopacińska Krystyna
Published: May 2023

This paper attempts to identify changes in the factors influencing the functioning and evolution of the Polish market for organic agricultural products. It brings together the results of surveys of farmers (carried out in 2011, 2019, and 2021), distributors (carried out in 2019 and 2021), and consumers (carried out in 2009 and 2021). Initially, farmers believed that the greatest opportunities for market development lay in demand factors, including in particular consumer environmental awareness. In 2021, their opinions worsened in this regard, which means they had difficulties reaching consumers. Another opportunity that was less popular than before was the EU subsidies. This is due to administrative and bureaucratic burdens, which, along with high production costs and weak links between farmers and distributors, were considered to be the biggest barriers to market development. For distributors, the survey produced similar conclusions. According to consumers, the greatest opportunities for market development result from increasing environmental awareness, increased diversity of products and better promotion. The barriers they highlighted include high prices, limited environmental education, lack of adequate state support, and insufficient information about the offer.

Authors: Szyja Paulina , Michalak Dorota
Published: May 2023

The article addresses the issue of climate security, a topic not sufficiently explored in the literature. The article aims to fill the literature gap on explaining the link between climate change and security, defining the term climate security, and attempting to select indicators (based on a selection from those already existing) for diagnosing the level of climatic security. The research established a lack of studies clarifying the term climate security. Hence, the authors’ definition was adopted. In turn, a review of existing indicators indicated their limitations. Nevertheless, it allows us to verify whether there is a threat to climate security.

Published: May 2023

The analysis is based on a sample of 1015 citizens from Czechia. The cognitive energy literacy index (CELI), based on the knowledge of the energy mix in electricity production and the knowledge of the import/export of electricity in Czechia, is constructed in this article. The research aims to answer the following questions: What is the level of CELI within the population of Czechia? To what extent do the selected socio-demographic indicators affect the CELI? To what extent does CELI influence respondents' perceptions?
The medium level of CELI is widespread across the population, while high and low levels of CELI are roughly equally shared. People with a high CELI are more likely to be older men with a university education. CELI also significantly affects the perception of behaviour on an individual, collective, and systemic level. Higher CELI is also associated with higher support for innovative solutions and renewable energy resources.

The mediating role of job satisfaction at selected public universities in Afghanistan: the effect of job security on turnover intention
Authors: Khawrin Mohammad Khalid , Sahibzada Abdurrasheed
Published: May 2023

The purpose of the study is to ascertain whether job satisfaction has a mediating role in the association between job security and the turnover at several public Universities in Afghanistan. The issue with the study is stated as follows. In addition to the significant impact employee, retention has on an organization's effectiveness; public colleges in Afghanistan nevertheless confront several challenges. An online Google form with a cross-sectional survey methodology was specifically utilized in this research's quantitative approach. The study’s researchers designed this normative measurement method. It has a Likert scale of five. The scale's validity and dependability were also examined. Cronbach's alphas for job security reliability, job satisfaction reliability, and job turnover reliability were 0.84, 0.68, and 0.87, respectively. An online Google form was employed to administer the convenience sampling technique. From several public universities in Afghanistan, 152 people took part. Job security had a major impact on job satisfaction. Furthermore, the intention to leave a job was significantly impacted by job security. Moreover, there was a sizable impact of job satisfaction on the intention to leave. In the association between job security and turnover intentions, job satisfaction had a strong mediating influence as well. Therefore, it is contended that job satisfaction plays a statistically positive and significant effect on job security and the intention of job turnover.

Pelatihan dibagi menjadi 5 macam kegiatan yaitu, persiapan, pre-test, pelaksanaan, post-test dan evaluasi. Pelatihan ini dilakukan dengan berbagai metode pembelajaran yang kemudian diukur Efektivitasnya menggunakan nilai pre-test dan post-test. Berdasarkan hasil pengukuran melalui kuesioner diketahui bahwa yang paling mempengaruhi penguasaan materi adalah Project Based Learning (PjBL). Efektivitas pembelajaran untuk pelatihan pengembangan web menggunakan PjBL secara online dinilai kurang efektif, hal ini dikarenakan hanya terdapat peningkatan nilai sebesar 4,81% dari pre-test terhadap post-test. Pelaksanaan pelatihan secara online ini juga mengalami penurunan jumlah peserta sebesar 65,91%, hal ini dipengaruhi oleh berbagai faktor penghambat yang dihadapi peserta seperti teknologi, psikologis, keuangan, manajemen waktu, dan keseimbangan antara kegiatan sehari-hari dengan pendidikan. Peningkatan efektivitas pembelajaran dapat dilakukan dengan cara memadatkan jadwal pelaksanaan yang menyesuaikan dengan daya tahan dari peserta yang berasal dari generasi Z / iGen.

Degayu Village is one of the areas affected by tidal floods in North Pekalongan District. Most of the rice fields of the residents of Degayu Village are currently submerged by 1-1.5 meters of tidal water which has forced some residents to change their profession from farmers to fishermen, anglers, fishing net craftsmen, and so on. However, with their new jobs, many residents find it difficult to adapt, resulting in a decrease in family income. For this reason, the Kelurahan government is trying to take advantage of the rice fields that have been submerged in water to become a potential for boat tourism so that economic growth can improve again. The tours offered are boat tours along the water while enjoying the natural scenery of the north coast. However, the results of in-depth interviews with several informants as well as direct observation of the location found the following problems; there are no work safety standards or procedures for boat tourism, for example, there are no life jackets and personal protective equipment for boats passengers and drivers, there is no rescue team in the event of an accident, no first aid facilities are available, and there is no tourism awareness group that manages the tourism potential properly. Well, besides the potential for boat tourism, there are also many other potentials that can be maximized, such as floating culinary tours, water bikes, mangrove parks, and so on. For this reason, it is necessary to form a tourism awareness group that is trained in tourism management both from an economic and work safety perspective.
