With the economic development and the carbon emissions cluster rise, this study uses CiteSpace, VOSviewer, and R-based Bibliometrix software to visualize and analyze the relevant literature on carbon emissions retrieved from the Web of Science database from 2014 to 2023. Through the analysis of the trend of publication volume, author co-citation analysis, institutional co-citation analysis, country co-citation analysis, literature co-citation analysis, thematic analysis of research, research evolution, and other related contents, it reveals the main academic forces, hot research areas, thematic focus changes and cutting-edge trends of international carbon emission research. The results of the study found that the themes of international carbon emissions research focus on carbon emissions, the drivers of carbon neutrality, and the impacts of climate change. An in-depth study of these aspects can help formulate more effective climate policies and emission reduction strategies to achieve global carbon neutrality and combat climate change.

The performance of Public Enterprises (PEs) in Namibia has been a long and contentious issue, clamored by continuous bailouts in the face of constant poor performance. The trend of financial bailouts to PEs in Namibia over the years has attracted increased attention into the dynamics of poor PE performance and their fiscal burden on the state. The Namibian government has taken active steps in cutting on PE bailouts and demanding improved performance or face closure. By looking at recent developments in the governance of PEs in Namibia, the purpose and objective of the current study is to analyze whether the current stance and trajectory of government decisions spells a post-honeymoon period in which poor performing PEs will ‘wither and survive or die’ if they do not improve their sustainability index by not relying on financial bailouts. This analysis is aided by the insights provided by the stakeholder, institutional and principal-agent theories. Through the qualitative research method, this study finds that the Namibian government has taken a new attitude and approach in which it will no longer blindly accept and tolerate the poor performance of PEs through continuous bailouts as seen in the past. PEs that are withering will now either survive (through reforms) or die (through liquidation or dissolution).

This paper focuses on examining the relationship among organizational factor, work-related factor, psychological factor, personal factor and the commitment of oil palm smallholders toward Malaysian Sustainable Palm Oil (MSPO) certification. The study employed a descriptive research methodology and a structured survey instrument to gather data from oil palm smallholders (n = 441) through simple random sampling technique. Data analysis was conducted using SPSS and partial least square structural equation modeling (PLS-SEM) to test the proposed relationship. The findings reveal that organizational factors significantly impact the affective (β = 0.345, p < 0.05), normative (β = 0.424, p < 0.05), and continuance commitment (β = 0.339, p < 0.05) of oil palm smallholders. Additionally, work-related factors show a substantial effect on these same dimensions of commitment; affective (β = 0.277, p < 0.05), normative (β = 0.263, p < 0.05), and continuance (β = 0.413, p < 0.05). Psychological factors significantly impact the affective (β = 0.216, p < 0.05) and normative commitment (β = 0.146, p < 0.05), with no statistically significant influence on continuance commitment. Conversely, personal factors exhibit limited influence, affecting only continuance commitment (β = 0.104, p < 0.05) to a minor degree, with no statistically significant impact on affective and normative commitment. The present research is among the few empirical findings that have examined the oil palm smallholders’ commitment towards MSPO certification. By emphasizing the role of organizational and work-related factors, the study offers valuable insights for stakeholders within the oil palm sector, highlighting areas to enhance smallholder commitment toward sustainability standards. Consequently, this study contributes a unique perspective to the existing body of literature on sustainable practices in the oil palm industry.

The study is devoted to the problem of processing the organic waste that is generated as a result of paper, textiles and other industries production as well as food waste. The growth of economic activity in Kazakhstan has resulted in a significant challenge with regard to industrial waste management. The accumulation of waste on the territory of the country has reached 31.72 billion tonnes, comprising approximately 2.5 billion tonnes of hazardous waste, 50 million tonnes of phosphorus-containing waste, over 2.5 million tonnes of lead-zinc waste and more than 120 million tonnes of solid domestic waste. The study object was the Shymkent-Kokys polygons. According to the research carried out, it was determined that the titer of microorganisms of the studied groups is 1–10 CFU/g in the soils selected around the garbage in the area of the Shymkent landfill. The titer of microorganisms in the soil horizons was high at a depth of 20–30 cm and the titer were 10⁹ cells/mL. The structure of the soil microbiome obtained around the Shymkent Waste Landfill consists of actinomycetes, micromycetes, heterotrophic bacteria, nitrifying, nitrogen-fixing bacteria, enterobacteria, as well as algae and protozoa. It was found that strains KPA1, KPA2 Pseudomonas sp. strains KPA3, KPA4, KPA5 Bacillus sp. isolated from the soils of the Shymkent-Kokys landfill are able to recycle domestic waste with a high content of cellulose and organic substances up to 95%–97%. The findings can be used to develop more effective organic cellulosic waste management strategies and improve the environmental sustainability of various industries.

 This article provides an account of the tourism in Petra encompassing its development from the time of the Nabataean Kingdom until the early 20th century. It delves into the factors that sparked tourism travel routes taken, security measures implemented, and influential individuals who have shaped Petra’s tourism history. Located at a juncture in the Middle East, Petra has consistently fascinated people with its sense of adventure. The city’s historical importance as a trade hub and a melting pot for cultural exchanges during the Nabataean era laid a strong foundation for its enduring charm. The skillful navigation of trade routes and effective marketing strategies employed by the Nabataean Kingdom played a role in establishing Petra as an irresistible destination for travelers. Supported by findings and ancient records it becomes evident that extensive trade networks flourished during this period highlighting the city’s role in the region. Its allure transcended generations captivating observers from Greece to its rediscovery by Burckhardt (1818–1897).
