Determination of Economic Sustainability Factors in Sheep Enterprises in Türkiye
No full textBackground: This study aimed to identify the primary factors influencing the economic sustainability of sheep enterprises in Türkiye. Materials and Methods: Data were collected through face-to-face surveys conducted with 201 enterprises across Ankara, Balıkesir, Erzurum, Eskişehir and Konya during the 2023 production period. The sample was selected using stratified random sampling, and the data were analysed using Statistical Package for the Social Sciences (SPSS) and Analysis of Moment Structures (AMOS) software, incorporating both exploratory and confirmatory factor analyses. Results: The results identified five key dimensions explaining economic sustainability: financial sustainability, innovation and investment, welfare, marketing and technical/productivity factors. The ‘Enterprise Performance Scale’ developed for this study proved to be a valid and reliable instrument (Kaiser–Meyer–Olkin [KMO] = 0.853; Cronbach's alpha = 0.867). Among these dimensions, the technical/productivity factor exhibited the highest influence and showed strong correlations with other factors (r = 0.828). The findings suggest that economic sustainability is a multidimensional construct, with the identified factors complementing one another. Conclusion: The findings indicate that economic sustainability in sheep enterprises is shaped by a multidimensional structure in which financial, technical and organizational capacities complement one another. Strengthening these dimensions particularly through improved marketing, technology adoption and producer cooperation can directly inform policy strategies aimed at enhancing the long-term resilience and competitiveness of the sheep farming sector in Türkiye
Moderating Effect of Terrorism in the Income Inequality-Military Expenditure Nexus: Evidence from Transition Economies
No full textPrior studies point to a significant correlation between income inequality and military expenditures. This study started by questioning whether the impact of terrorism on this relationship may have been neglected. The main purpose of the study is to demonstrate whether the terrorism variable has a significant effect on the direction and strength of the nexus between military expenditures and income inequality. As such, the effect of terrorism has been analyzed using as a moderator variable. Forecasts for 26 transition economies and the 2002–2020 period have been performed using three different models. The first two models are baseline models, and in the third model, the moderator effect is included with all the control variables. Three different income groups (top 10, middle 40, and bottom 50) have been selected as indicators of income inequality. We also confirm the results by utilizing the income inequality indicator (gini_disp) of the Standardized World Income Inequality Database (SWIID). All three model findings signalize a positive finding similar to previous literature in the relationship between income inequality and military expenditure. However, the stand-alone and moderator effects of terrorism vary between income groups. For the top 10 and middle 40 income groups, terrorism correlates inversely with income inequality according to Model 1 findings, and in the same direction for the bottom 50. For the top 10 and middle 40 income groups, the moderator effect of terrorism in the inequality-military expenditure relationship is positive (Model 2). The direction of the effect is positive when control variables are added (Model 3). For the bottom 50 income group, the moderator effect of terrorism is in the same direction (positive) for Models 2 and 3. Our results illustrate that decision-makers in terrorism-affected transition economies may be puzzled regarding the opportunity cost of social welfare expenditure for low incomes against military expenditure

No full textGenomic insight into Anoxybacillus dikiliensis sp. nov., a hot spring isolate from Dikili exhibiting biotechnologically important features
No full textGram-positive, thermophilic, endospore-forming, yellow, rod-shaped bacteria, D401aT and D404, were isolated from soil samples of a hot spring in Dikili, Izmir. They can synthesize silver nanoparticles and biotechnologically important thermostable alpha-amylase, alpha-glucosidase and nitrate reductase, which were also confirmed by in silico analyses. 16S rRNA gene phylogenetic analysis revealed that D401aT was most closely related to D404 (99.9%) and had less than 98.9% similarity to Anoxybacillus flavithermus DSM 2641T, Anoxybacillus thermarum DSM 7141T, Anoxybacillus mongoliensis DSM 19169T and Anoxybacillus ayderensis from the genus Anoxybacillus. Their 2.7 Mb whole-genome analyses indicated that strains D401aT and D404 represented a novel species within the genus Anoxybacillus, by displaying low average nucleotide identity and in silico DNA-DNA hybridization values between A. ayderensis DSM 14988 (92.9%-50.5%), A. ayderensis DSM 10112T (92.4%-48.6%), A. thermarum DSM 17141T (92.6%-48.8%) and Anoxybacillus gonensis NCIMB 13933T (91.3%-43.8%) below 95% and 70%, respectively. The G+C content of genomic DNA was calculated to be 42.0 mol%. The percentage of conserved protein values of two strains within the genus Anoxybacillus ranged from 89.3% to 85.0% and average amino acid identity values from 95.1% to 91.6%, indicating the overall genus-specific boundaries. In silico chemotaxonomic analysis revealed the presence of complete gene sets encoding iso-C15:0, iso-C17:0 and C16:0 fatty acids, menaquinone-7, polar lipids of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and meso-diaminopimelate-type peptidoglycan were identified. Their genomes encoded type III polyketide synthases that produce biotin. They harboured additional terpene/carotenoid and terpene precursor biosynthetic clusters with secondary metabolites of carotenoids (C30), vitamin E and sesquiterpenes (C15). By morphological, physiological, phylogenetic and phylogenomic features, D401aT and D404 are assigned to be a new species of the genus Anoxybacillus, which the name Anoxybacillus dikiliensis sp. nov. is proposed (type strain D401aT=DSM 120222T=NCIMB 15614T)
