Low temperature is one of the most significant environmental factors that threaten the survival of subtropical and tropical plant species. By conducting a study, which was arranged in a completely randomized design with three replicates, the relative freezing tolerance (FT) of four Iranian pomegranate cultivars, including ‘Alak Torsh’, ‘Tabestaneh Torsh’, ‘Poost Sefid’, and ‘Poost Syah’, as well as its correlation with some biochemical indices, were investigated. From each cultivar, pieces of one-year-old shoot samples were treated with controlled freezing temperatures (−11, −14, and −17 ℃) to determine lethal temperatures (LT50) based on survival percentage, electrolyte leakage, phenolic leakage, and tetrazolium staining test (TST) methods. Results showed that FT was higher in the second year with a lower minimum temperature and a higher concentration of cryoprotectants. The stronger correlation of electrolyte leakage with survival percentage (r = 0.93***) compared to the other three indices explained that this index could be the most reliable injury index in determining the pomegranate FT to investigate freezing effects. Of all four cultivars, ‘Poost Syah’ was the hardest by presenting a higher FT than ~ −14 ℃ in mid-winter. Accordingly, this pomegranate cultivar seems to be promising to grow in regions with a higher risk of freezing and to be involved in breeding programs to develop novel commercial cultivars.
This research aims to explain the management of the Cekungan Bandung Urban Area with a focus on three policy formulations, namely process, content and context in the social, environmental and economic dimensions. The research method used is a qualitative approach. Data collection techniques include observation and interviews with stakeholders, using purposive sampling techniques, including the Head of West Java Province Regional Development Planning Agency, district/city Bappeda heads, planners (Badan Perencanaan Dan Pembangunan Daerah, Bappeda), Regional People`s Representative Assembly (Dewan Perwakilan Rakyat Daerah, DPRD members), Legal Bureau and Collaboration Bureau Heads in West Java Province, and Academic Manuscript Compiler. Due to the absence of comfortable, safe, and punctual public transportation, people continue to use private vehicles, leading to unresolved traffic congestion and environmental pollution, thus resulting in economic losses. The results show the formulation of policies for managing the urban area of the Cekungan Bandung, specifically the establishment of BP Cek ban, faced challenges due to a lack of authority in managing financial and human resources. The agency couldn’t execute programs or activities and implement the development due to limitations in legal authority over state finances. Alternative policies were not effectively synchronized between government levels and lacked legislative support, hindered by regional autonomy. The contribution of the research is as reference material for the government in formulating management policies for the Cekubgan Bandung urban area.
The mining sector faces a complex dilemma as an economic development agent through social upliftment in places where mining corporations operate. Resource extraction is destructive and non-renewable, making it dirty and unsustainable. To ensure corporate sustainability, this paper examines the effects of knowledge management (KM), organizational learning (OL), and innovation capability (IC) on Indonesian coal mining’s organizational performance (OP). We used factor and path analysis to examine the relationships between the above constructs. After forming a conceptual model, principal component analysis validated the factor structure of a collection of observed variables. Path analysis examined the theories. The hypothesized framework was confirmed, indicating a positive association between constructs. However, due to mining industry peculiarities, IC does not affect organizational performance (OP). This study supports the importance of utilizing people and their relevant skills to improve operational performance. The findings have implications for managers of coal mining enterprises, as they suggest that KM and OL are critical drivers of OP. Managers should focus on creating an environment that facilitates knowledge sharing and learning, as this will help improve their organizations’ performance.
We analyzed the relationship between nutrient (N and K) parceling and population density on the severity of onion downy mildew under no-tillage fertigation cultivation in the conditions of Alto Vale do Itajaí (Barzil). For this purpose, field trials were conducted in the years 2017, 2018 and 2019, in Ituporanga (Barzil). The treatments corresponded to four population densities (300, 400, 500 and 600 mil plants ha-1) subjected to applications of nitrogen (150 kg N ha-1) and potassium (127.5 kg K2O ha-1) distributed throughout the vegetative cycle of the crop via fertigation on a weekly, biweekly and monthly basis, based on the absorption curve of these nutrients for the cultivar Empasc 352-Bola Precoce. In fertigated no-tillage systems, nutrient (N and K) tranches do not influence the severity of downy mildew. The severity of downy mildew increases linearly with increasing population density, especially from 500 mil plants per ha-1.
This paper discusses the use of workforce ecosystems to manage human intellectual capital. The need for work ecosystems has emerged in the digital age because of the rapid growth in the number of engaged partners and freelancers in the digitalization of enterprises. It is shown that this growth is directly related to the use of agile management systems in design and development: agile, DevOps, microservice architecture, turquoise practices, etc. The information systems needed to manage workforce ecosystems should have competency-based metrics to link business needs, recruitment and training, and finding new partners. At the same time, training should be prioritized over recruitment and the search for new partners in the context of staff shortages. When automating workforce ecosystems, a platform approach should be used to integrate both corporate HR, time and business process management systems, and similar systems from partners.
This study aims to determine the effect of Human Capital Management (HCM) and work ethics on the performance of life insurance agents mediated by Organizational Citizenship Behavior-Organization (OCB-O) and Organizational Citizenship Behavior-Individual (OCB-I). The data was collected from 103 respondents who had entered the category of having won the Top Agent Awards (TAA) using a survey approach with questionnaires. The population consisted of life insurance agents who had won the TAA/MDRT, a 5 Likert scale questionnaire, and analyses using the SEM-AMOS-21 program. The results prove HCM has a positive significant effect on work ethics; HCM does not have a substantial impact on OCB-O and OCB-I; Work Ethics have a considerable effect on OCB-I and OCB-O; OCB-O and OCB-I have no significant impact on performance; HCM does not have a substantial effect on performance; Work Ethics does not have a considerable impact on performance, however, if OCB-I mediates HCM it will strengthening agent Performance, likewise, Work Ethics if mediated by OCB-I, will strengthening Performance. The findings of this study are that for insurance agents to perform well, companies can treat agents as HCM and work ethics, and it is essential to pay attention to OCB-I as mediation in improving agent performance.
