In business schools in Western countries, acting is used as a tool for training managers. However, in the Eastern countries, including Romania, the concept is underdeveloped. In this scientific research, the opinion of both business professionals, i.e., managers with experience in this field, and students from the Faculty of Business and Tourism within The Bucharest University of Economic Studies on the usefulness of introducing acting courses to support the training of managers is investigated. The professionals interviewed believe that acting benefits a manager through the leadership and communication lessons it provides, helping them to manage situations by appealing to emotional memory, relating to their team members by using emotional intelligence, and sharing their vision by developing the qualities necessary for a leader. The students' perspective underscores the ideas expressed by practicing managers and demonstrates that management contains an artistic component to a significant degree and that acting as an art form is intertwined with management in beneficial ways. The overall conclusion of the study highlights students' confidence in the impact of acting on a manager's professional development. The percentage of students who would take acting courses if they were introduced in Romanian business schools is over 90% of all respondents. Thus, it can be stated that acting is a real tool for the development of a manager, which should be adopted and used by all Romanian business schools.

The tourists’ decision-making process and sharing behaviors while travelling and social media are intertwined, especially for the young tech-savvy generations. Nevertheless, papers comparing generation Y and Z in this respect are scarce. By surveying two samples, this paper aims to investigate if generations Y and Z are different in terms of social media use for travelling purposes. The results indicate Centennials get more information about journeys from social networks. Moreover, they give more value to online photos during the travel decision-making than generation Y. During the actual journey, Centennials depend less on Facebook and more on Instagram than Millennials. The two samples are significantly different in terms of sharing behavior of their travel experiences. Last but not least, the number of hours spent daily on social media influences the usage of social media while travelling for both generations.

The intense competition and unpredictable challenges in hotel operations in Sri Lanka have led to the need to adopt new technologies to provide better services to guests and maximise efficiency and effectiveness. Therefore, the main objectives of this study were to examine various Artificial Intelligence tools used in hotels in Sri Lanka, explore managers' perceptions of Artificial Intelligence, and identify barriers to the implementation of Artificial Intelligence in hotels in Sri Lanka. Using a purposive sampling, 15 managers of star category hotels in the Colombo district were selected and interviewed using a structured interview method to explore the objectives. The findings derived from the thematic analysis showed that hotels in Sri Lanka have limited knowledge of AI applications and that the respondents' perception of AI technology is still at an early stage where they doubt and question its effectiveness compared to human resource services. The study found that the use of AI technology has significant potential, especially in new and emerging hotels, as these new hotels tend to engage with tech-savvy guests compared to existing hotels in Sri Lanka. Moreover, technological advancements in artificial intelligence will undoubtedly lead to an unimaginable hotel experience that will increase guest satisfaction in Sri Lanka's hotel industry.

The forage cactus stands out in animal feed, as it adapts to the climatic conditions of the semi-arid region and has a high-water content with benefits for animals fed with this forage plant. The objective of this study was to evaluate the agronomic and mineral characteristics of different forage cactus varieties managed under phosphate fertilization. A randomized blocks design was used, with split-plots in the space, the plots being the forage cactus varieties (Giant sweet clone (Nopalea cochenillifera (L.) Mill.), Little sweet clone (Nopalea cochenillifera (L.) Mill) and Mexicana (Opuntia tuna (L.) Mill)) and the subplots the doses of phosphorus (0, 30, 60 and 90 kg P ha-1 year), with four repetitions. The evaluations and cuts were performed two years after planting. The data were submitted to analysis of variance with significance level of 5%. In the mean comparison between the forage cactus pear varieties, the Tukey’s test was used. Statistical analyzes were performed using the software SISVAR. The variety Mexicana presented higher values of perimeter, width, and green mass per plant. The variety Giant sweet clone obtained higher values of thickness and length. The highest number of cladodes and the shortest length, perimeter and width were observed on the variety Little sweet clone. Regarding the variety Little sweet clone, a quadratic response was observed for the mineral matter, calcium, zinc and manganese contents and linear response for phosphorus and iron contents, in relation to the increase of phosphorus doses. Mexicana and Giant sweet clone varieties presented quadratic response in the doses of phosphorus for calcium, iron, zinc, and manganese contents. Phosphate fertilization promotes important changes in the agronomic characteristics of the cactus pear varieties, especially in the increase of cladodes and yield. The minerals of the cactus pear are affected by the dosage of the phosphate fertilizer and by the genotypic difference of the plant.

The Cactus Opuntia spp. plant is important to Morocco's arid and semi-arid regions. The edible and cosmetic oil from prickly pear fruit seeds is very prized. Since Dactylopius Opuntiae first appeared in Morocco in 2014, hundreds of hectares of cactus have been devastated, causing environmental and socio-economic costs. Eight D. Opuntiae resistant varieties were selected, multiplied and transplanted throughout Morocco, as part of the government's nationwide cactus rehabilitation program. This research evaluated the production and fatty acid composition of the seed oil of these varieties. Oil extraction was carried out with the Soxhlet method using hexane and by mechanical screw press. The crude seed oil content obtained by hexane extraction ranged from 9.54% to 16.44% (w/w). Mechanical screw extraction recovered half the seeds' oil. The fatty acid profiles showed that the oils were highly unsaturated; UFA fraction represented 76.31 to 82.63% of total FA and UFA/SFA ratio of 3.48 to 5.36. Linoleic acid was the dominant and represented 61.50% to 68.35% of total FA. These results highlight the importance of cochineal-resistant cactus varieties as oil sources and alternatives to those destroyed and still threatened by the harmful scale pest that appeared in more than 20 countries.

The ongoing conflict in Ukraine has had a significant impact on the country's tourism industry, with many regions becoming inaccessible or unattractive due to safety concerns. VR tourism in war zones, a form of tourism that involves visiting areas affected by conflict, disaster, or civil unrest, has become a topic of interest in the context of the war in Ukraine. To investigate the intention to use VR tourism in the war zone, an integrated framework was proposed by combining key elements such as interest in VR tourism in the war zone and the technology acceptance model (TAM). A sample of 121 respondents was collected in January 2021, and hypotheses were tested using a PLS-SEM model. This research tested a conceptual model that showed that the intention to use VR tourism in the war zone was influenced by perceived ease of use, perceived usefulness, and attitude toward the use of VR tourism in the war zone, all partially or fully mediated by people's interest in VR tourism in the war zone. This paper has theoretical and managerial implications.

Pitahaya (Hylocereus spp.) has been placed successfully in the global fruit market due to its exotic appearance and pleasant flavor; however, its short postharvest life has limited its marketing in national and international markets. The postharvest life and final quality of fruits depend on the state of maturity in which the fruit is harvested, as well on the storage conditions. The aim of this study was to assess the postharvest behavior of pitahaya fruits (H. ocamponis) harvested during two states of maturity (pre-consumer and consumption maturity), stored at 6 ± 1°C and 22 ± 3 °C for 24 days. The color, firmness, epicarp thickness, weight loss, soluble solids, total soluble sugars, betalains, phenolic compounds and antioxidant activity showed significant changes during the storage period. The preserved fruits at room temperature maintained their firmness and color of the epicarp, content of soluble solids, soluble sugars and betalains during 9 days of storage, but from the 16th day, they showed rottenness and degradation of epicarp betalains. In contrast, the stored fruits in refrigeration presented a lower weight loss, greater firmness, and epicarp thickness, reaching 24 days of shelf life. The antioxidant activity was greater in the pulp of the stored fruits at 22 °C, due to an apparent higher betalains concentration associated with greater water loss in the fruit.

The establishment of Pachycereus pringlei seedlings is a scarce event; soil conditions are one of the factors attributed to its high mortality rate in the early stages of development. The use of organic manures as a substrate helps to improve the structure, porosity, and density of the soil where they live, in addition to providing nutrients that would benefit the roots, increasing the possibility of their establishment during the emergence stage. The objective of this study was to evaluate the effect of different proportions of organic manures as a sown substrate in the emergence and establishment of Pachycereus pringlei seedlings, using nine treatments of organic manures in a completely randomized experimental design with four replications. The variables measured were emergence rate (ER) and percentage (EP) and their indices, seedlings’ morphometric, and physiological characteristics in the establishment stage. The results showed that the evaluated variables in the emergence and seedling establishment phase indicate the preference for natural substrate and organic manure combinations in proportions of 50 and 30%, respectively. The analysis of variance showed significant differences regarding the morphometric and physiological variables of the stem and root of the evaluated treatments. The emergence and establishment analyses show that cardon seedlings under different organic manure treatments and controlled conditions had excellent survival results compared to the low rates of recruitment and survival reported under natural conditions. Similarly, the implementation of organic manures improved the physiological and morphometric characteristics of the cardon seedlings compared to the control treatment with the natural substrate.

The use of organic manures as a substrate helps to improve the structure, porosity, and density of the soil where they live, in addition to providing nutrients that would benefit the roots, increasing the possibility of their establishment during the emergence stage. The objective of this study was to evaluate the effect of different proportions of organic manures as a sown substrate in the emergence and establishment of Pachycereus pringlei seedlings, using nine treatments of organic manures in a completely randomized experimental design with four replications. The variables measured were emergence rate (ER) and percentage (EP) and their indices, seedlings’ morphometric, and physiological characteristics in the establishment stage. The results showed that the evaluated variables in the emergence and seedling establishment phase indicate the preference for natural substrate and organic manure combinations in proportions of 50 and 30%, respectively. The analysis of variance showed significant differences regarding the morphometric and physiological variables of the stem and root of the evaluated treatments. The emergence and establishment analyses show that cardon seedlings under different organic manure treatments and controlled conditions had excellent survival results compared to the low rates of recruitment and survival reported under natural conditions. Similarly, the implementation of organic manures improved the physiological and morphometric characteristics of the cardon seedlings compared to the control treatment with the natural substrate.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48222260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
