The semi-arid is a climate characterized by precipitation that is. insufficient to maintain crops and where evaporation often exceeds rainfall. Vegetation is one of the most sensitive indicators of environmental changes understanding the patterns of biodiversity distribution and what influences them is a fundamental pre-requisite for effective conservation and sustainable utilization of biodiversity. In this study. our focus was on examining the vegetation diversity in the semi-arid region of Tebessa. which falls within the Eastern Saharan Atlas domain in North Africa’s semi-arid zone. Plants were sampled at 15 sites distributed across the study area. The quadrat method was used to conduct floral surveys. The sampling area of each sample was 100 square meters 10 m × 10 m (quadrat). Each quadrat was measured for species richness (number of species). abundance (number of individuals). and Richness generic (plant cover). Based on the floristic research. 48 species were found. classified into 21 families. with Asteraceae accounting for 34.69% of the species and Poaceae accounting for 14.28%.

Nomophobia, the anxiety experienced when individuals are separated from their mobile phones, is becoming increasingly prevalent in modern workplaces. This study investigates the role of organizational commitment in mitigating nomophobia, with a focus on the mediating influence of the ethical environment. Data were collected from 600 participants and analyzed using Structural Equation Modeling (SEM). The findings show that a strong sense of organizational commitment significantly reduces nomophobia among employees. Additionally, an ethical environment within organizations further mitigates this anxiety by fostering a workplace culture that encourages psychological well-being. This research provides practical insights for organizations looking to reduce the psychological strain associated with digital dependency, emphasizing the importance of both commitment and a strong ethical climate.

One of Indonesia’s main characteristics of tourism development is maritime tourism, which is synonymous with archipelagic countries. The diversity of maritime tourism offered by Indonesia will never end, so it needs to be considered more carefully and used relevantly to create sustainable tourism in Indonesia that provides broad benefits for the country. Many maritime tourism locations in Indonesia are beautiful but require more active promotion. The level of security and terrorism issues are a requirement that the government must consider. The novelty of this research describes the potential ecotourism development in the town of Makassar that stakeholders should consider in the formation of tourism policy. The research locations are in Makassar City, Samalona Island, Langkai Island, and Lanjukang Island. Ecotourism developed in the coastal areas of Makassar City, especially in Samalona, Lanjukang, and Langkai Islands, produces superior objects that collaborate elements of nature and society as the main attraction in the long term. Therefore, local governments need to strengthen monitoring of regional geopolitical developments in order to avoid security and terrorism problems that might cause inconvenience to tourists.

Disease epidemics may spread quickly and easily throughout nations and continents in our current global environment, having a devastating effect on public health and the world economy. There are over 513 million people worldwide who have been infected, and more than 6.2 million have died due to SARS-CoV-2. There are treatments but no cures for most viruses. Nevertheless, the spread of viruses can be limited by introducing antiviral coatings on public area surfaces and personal protective equipment (e.g., face masks). This work aims to fabricate a polymer-based coating with acrylic resin as a binder that possesses great antiviral activity against the Feline coronavirus (FCov). The chosen polymer, polyethylene glycol (PEG), is used as an antiviral agent because it contains “green” chemistry benefits such as non-toxicity, being inexpensive, readily recyclable, safe, natural, non-flammable, biocompatible, and biodegradable. The PEG/acrylic coating systems of different weight percentages were coated on the glass substrates by the spray-coating method and cured at room temperature for 24 hours. The developed PEG/acrylic coating system that contains 20 wt% of PEG exhibits the highest anti-viral activities (99.9% against FCov) compared to the other weight percentages. From this study, it has been observed that the hydrophilicity of the coating plays an important role in its antiviral activity. The developed coating has a hydrophilic property, in which the contact angle was measured at 83.28 ± 0.5°. The FTIR reveals that there are no existing toxic components or new components contained in the coating samples.

Public-Private Partnerships (PPPs) are mostly presented as a means to introduce efficient procurement methods and better value for money to taxpayers. However, the complexity of the PPP mechanism, their lack of transparency, accounting rules and implicit liabilities make it often impossible to perceive the amount of public expenditure involved and the long-run impact on taxpayers, providing room for fiscal illusion, i.e., the illusion that PPPs are much less expensive than traditional public investments. This psaper, thanks to a systematic review of the literature on the EU countries experience, tries to unveil the sources of this illusion by looking at the reasons behind the PPPs’ choice, their real costs, and the sources of fiscal risks. The literature suggests that PPPs are more costly than public funding, especially when contingent liabilities are not taken into account, and are employed as mechanisms to circumvent budgetary restrictions and to spend off-balance. The paper concludes that the public sector should share more risks with private sectors by reducing the amount of guarantees, and should prevent governments from operating through a sleight of hand that deflects attention away from off-balance financing, by applying a neutral fiscal recording system.
