The Effects of Depth-Related Environmental Factors on Traits in Acropora cervicornis Raised in Nurseries

Populations of Acropora cervicornis, one of the most important reef-building corals in the Caribbean, have been declining due to human activities and global climate change. This has prompted the development of strategies such as coral farms, aimed at improving the long-term viability of this coral across its geographical range. This study focuses on comprehending how seawater temperature (ST), and light levels (LL) affect the survival and growth of A. cervicornis fragments collected from three reefs in Culebra, Puerto Rico. These individuals were fragmented into three pieces of the similar sizes and placed in farms at 5, 8, and 12 m depth. The fragments, ST and LL were monitored for 11 months. Results show that fragments from shallow farms exhibit significantly higher mortalities when compared to the other two depths. Yet, growth at shallow farms was nearly 24% higher than at the other two depths. Corals grew fastest during winter, when temperature and LL were lowest, regardless of the water depth. Fragment mortality and growth origin were also influenced by reef origin. We conclude that under the current conditions, shallow farms may offer a slight advantage over deep ones provided the higher growth rate at shallow farms and the high fragment survival at all depths.

Creativity in the South Korean Workplace: Procedural Justice, Abusive Supervision, and Competence

Innovation is now a feature of daily life. In a rapidly changing market environment and amid fierce competition, organizations pursue survival and growth through innovation, and the key driver of innovation is the creativity of employees. Because the value of creativity has been emphasized, many organizations are looking for effective ways to encourage employees to be creative at work. From a resource perspective, creativity at work can be viewed as a high-intensity job demand, and organizations should encourage it by providing and managing employee resources. This study is an attempt to empirically investigate how competence and abusive supervision affect the relationship between procedural justice and creativity from the conservation of resources perspective. Findings from two-wave time-lagged survey data from 377 South Korean employees indicate that procedural justice increases creativity through the mediation of competence. Furthermore, abusive supervision has a negative moderating effect on the relationship between procedural justice and competence. The findings show that competence moderates the relationship between procedural justice and creativity and that the lower the level of abusive supervision, the greater the effect of procedural justice on competence and creativity.

Servant Leadership Styles as a Challenge to Develop Innovation in Resilient Environments

The current challenge for the survival and growth of companies is the appropriation of innovation in all its senses, the generation of propitiate resilient environments, the innovation philosophy acquisition into action, and improve internal dynamics and cohesion through a comparison of leadership styles oriented by the motivation to serve as a servant leadership. This chapter analyses the relevance of the culturally intelligent organizations to carry out innovation. Likewise, the styles of servant leadership and administration that generate a collective consciousness tend to create innovation and more resilient environments.

Business development in events

The challenges associated with establishing an events enterprise, or growing and sustaining an existing enterprise, share several of the features that characterise business development more generally. As with other industries, the development of a realistic and understandable business model is crucial when setting up event businesses. At the same time, most successful organisations in the events industry owe their initial existence, as well as their ongoing survival and growth, to the efforts, expertise, and tenacity of entrepreneurs.

Impacts D’une Technique De Restauration De Terre Dégradée Sur La Survie Et La Croissance Des Plants De Quatre Espèces De Combretaceae En Zone Sahélienne Du Niger

Les banquettes sylvopastorales constituent l’une des techniques les plus utilisées au Niger pour restaurer les terres dégradées de plateaux. La présente expérimentation a été réalisée sur un plateau dégradé de Simiri dans l’Ouest nigérien où des banquettes sylvopastorales ont été installées. L’objectif est d’évaluer la survie et la croissance des plants de quatre essences locales de Combretaceae, Combretum glutinosum, Combretum micranthum, Combretum nigricans et Guiera senegalensis. Les méthodes utilisées ont consisté d’abord à délimiter un espace sur le plateau dégradé où 40 banquettes sont confectionnées et un autre espace sans banquette pour servir de témoin. Dans les banquettes, 200 plants de chaque espèce ont été plantés à raison de 20 plants/banquette. Deux mois après la plantation un suivi périodique de l’humidité du sol et des paramètres dendrométriques des plants a été effectué durant 30 mois. Les paramètres dendrométriques mesurés sont le taux de survie, la hauteur et le diamètre au collet du grand axe caulinaire, le nombre de rejets et de feuilles. Les résultats obtenus ont montré d’une part que les banquettes améliorent les conditions hydriques du sol de 18,19 % par rapport à la zone non traitée (sans banquette) et d’autre part que les meilleurs taux de survie et de croissance ont été observés au niveau des espèces Guiera senegalensis, Combretum. glutinosum et Combretum. micranthum. Ainsi, les espèces Guiera senegalensis, Combretum glutinosum et Combretum micranthum peuvent être utilisées dans le reboisement de sites aménagés avec des banquettes sylvopastorales pour restaurer les terres de plateaux au Niger Silvopastoral banquettes are one of the techniques mostly used in Niger to restore degraded plateau lands. The present experiment was carried out on a degraded Simiri plateau in western Niger where silvopastoral banquettes have been installed. The objective is to assess the survival and growth of plants of four local species of Combretaceae, Combretum glutinosum, Combretum micranthum, Combretum nigricans, and Guiera senegalensis. The methods used consisted first of delimiting a space on the degraded plateau where 40 banquettes are made and another space without a banquette to serve as a control zone. In the banquettes, 200 plants of each species were planted at 20 plants/banquette. Two months after planting, periodic monitoring of soil moisture and dendrometric parameters of the plants was carried out for 30 months. The dendrometric parameters measured are the survival rate, the height and the collar diameter of the stem axis, the number of suckers and leaves. The results obtained showed on the one hand that the banquettes improve the water conditions of the soil by 18.19% compared to the untreated zone (without banquettes) and on the other hand that the best survival and growth rates were observed at the level of the species Guiera senegalensis, Combretum. glutinosum and Combretum. micranthum. Thus, Guiera senegalensis, Combretum glutinosum, and Combretum micranthum species can be used in the reforestation of sites developed with silvopastoral banquettes to restore plateau lands in Niger.

Strategy Development for Survival & Growth of MRO Company during & Post Covid-19 Pandemic (Case Study: GMF Aeroasia)

Indonesian Aviation Market 2020 was predicted to grow around 7.0% compared to 2019. It gave Indonesian MRO industry an optimism at first, at least in the beginning of the year, before WHO declared COVID-19 pandemic in March 2020. The COVID-19 pandemic has a dire impact on the aviation & MRO industry. As of July 2021, flights still haven’t reached 50% compared to pre-COVID era. Many MRO companies, including GMF AeroAsia, must face an unprecedented situation that caused the market to shrink significantly, and enter the financial distress zone. Several initiatives have been taken by the company. However, with the protracted pandemic conditions and the uncertainty of Indonesian Aviation Market recovery, further strategies are needed to survive and growth. This study aims to analyze the company and develop a strategy based on 2 stages, namely the retrenchment phase and the recovery phase. The retrenchment phase will focus on the survival strategy, while the recovery phase will focus on the growth strategy using scenario planning because the future is still uncertain. From the analysis and interviews, several initiatives and strategies for survival and growth were developed. Several initiatives for survival include headcount cuts, operational efficiency, product elimination, liquidation & divestment, equity for debt swaps, and renegotiate with lenders. While the growth strategy was developed based on 4 scenarios, namely Flying Through Thunderstorm, Flying with Engine Failure, Flying with Broken Wings, and Flying Zig-Zag.

Temperature ranges for survival and growth of juvenile Saccharina sculpera (Laminariales, Phaeophyta) and applications for field cultivation

Saccharina sculpera is highly valued for human consumption and value-added products. However, natural resources of this kelp have decreased sharply and it is in danger of extinction. Resources recovery through cultivation is being trialed to enable the sustainable use of this species. In this study, the temperature range for survival and optimal growth of juvenile S. sculpera was identified and applied to field cultivation. This study investigated the survival and growth of juvenile S. sculpera under six temperatures (i.e., 5, 10, 15, 16, 18, and 20°C) and two light intensities (i.e., 20 and 40 μmol photons m-2 s-1) in an indoor culture experiment. In these experiments, the blade length decreased at 16°C under the both light intensities. The thalli died at 20°C and 20 μmol photons m-2 s-1, and at 18‒20°C and 40 μmol photons m-2 s-1. During the field cultivation, early growth of S. sculpera was highest at the 5 m depth and growth decreased as the water depth increased. When the initial rearing depth was maintained without adjustment throughout the cultivation period (from December to October), all the cultivated S. sculpera plants died during August and September. However, S. sculpera plants lowered from 5 to 15 m and grew to 90.8 ± 13.1 cm in July. The seawater temperature at 15 m depth was similar to the upper level of thermal tolerance demonstrated by juvenile S. sculpera in the indoor culture experiments (16°C or lower). The plants were subsequently lowered to 25 m depth in August, which eventually led to their maturation in October. The present study confirmed that improved growth rates and a delay in biomass loss can be achieved by adjusting the depth at which the seaweeds are grown during the cultivation period. These results will contribute to the establishment of sustainable cultivation systems for S. sculpera.
