Hutan Mangrove merupakan suatu ekosistem laut yang memiliki peran penting sebagai penyimpan karbon tertinggi di wilayah tropis. Fungsi mangrove ini dapat membantu dalam mengurangi emisi karbon dan pemanasan global. Pulau Nyamuk dan Pulau Parang merupakan vegtasi alami yang mengalami penurunan luasan mangrove yang diduga disebabkan oleh alih fungsi lahan, sehingga akan menyebabkan penurunan fungsi mangrove dalam menyerap CO2. Tujuan dilakukannya penelitian ini adalah menganalisis dan menduga total simpanan karbon dan serapan CO2 pada tegakan mangrove di Pulau Nyamuk dan Pulau Parang. Manfaat dilakukanya penelitian ini adalah memberikan informasi mengenai manfaat mangrove sebagai penyerap karbon. Pengambilan data yang dilakukan dalam penelitian ini menggunakan purposive sampling method, dimana setiap lokasi memiliki 3 stasiun (Pulau Nyamuk; Sareh Besar, Sareh Kecil, Ujung; Pulau Parang: Batu Merah, Plawangan, Batu Hitam). Setiap stasiun dibagi menjadi 3 plot untuk dilakukan pengambilan data diameter batang mangrove. Data diameter batang mangrove digunakan untuk menghitung nilai biomasssa tegakan dengan menggunakan rumus allometrik dalam menduga simpanan karbon pada tegakan mangrove suatu area. Hasil penelitian menunjukan bahwa simpanan total karbon pada tegakan mangrove di Pulau Nyamuk memiliki nilai 1.176,48 ton/ha, yang dibagi sebagai berikut: Stsiun Sareh Kecil: 383,16 ton/ha, Stasiun Sareh Besar: 419,51 ton/ha, dan Stasiun Ujung: 373,81 ton/ha, sedangkan di Pulau Parang memiliki nilai 2009.031 ton/ha, yang dibagi sebagai berikut: Stasiun Batu Merah 767,672 ton/ha, Stasiun Batu Hitam 654,444 ton/ha, dan Stasiun Plawangan 586,915. Mangrove Forest is a marine ecosystem that has an important role as the highest carbon storage in the tropics. This mangrove function can help in reducing carbon emissions and global warming. Nyamuk Island and Parang Island are natural vegetation which decrease mangrove area which is caused by land conversion function, so it will cause mangrove function to absorb CO2. The purpose of this research is to analyze and estimate total carbon storage and CO2 uptake on mangrove stands in Nyamuk Island and Parang Island. The benefit of this research is to provide information about the benefits of mangroves as carbon sinks. The data collected in this research using purposive sampling methods, where each location has 3 stations (Nyamuk Island: Sareh Besar, Sareh Kecil, Ujung; Parang Island: Batu Merah, Plawangan, Batu Hitam). Each station is divided into 3 plots for data collection of mangrove stems diameter. The mangrove stem diameter data were used to calculate the stand biomass value by using allometric formula in estimating carbon stock in the mangrove stand of an areas. The results of research, that total carbon deposits in mangrove stands in Nyamuk Island had a value of 1,176.48 tons/ha, divided as follows: Sareh Kecil Station: 383.16 tons / ha, Sareh Besar Station: 419.51 tons / ha, and Ujung Station: 373,81 ton / ha, while in Parang Island has value 2009.031 ton / ha, which is divided as follows: Batu Merah Station 767,672 ton / ha, Batu Hitam Station 654,444 ton / ha, and Plawangan Station 586,915.

AbstractBackgroundEarly career doctors (ECDs) are faced with many challenges due to their transition from undergraduate medical/dental studentship to being postgraduate doctors and being in an early phase of their career. The specific factors that affect ECDs in their careers and endeavors at the workplace range from poor remuneration, particularly in developing countries, to psychosocial problems (such as burnout [BO] syndrome). There is a dearth of information on BO among ECDs in Nigeria. This qualitative study aims to explore the opinions of ECDs in Nigeria on the causal/predisposing factors of BO, effects of BO, and strategies for mitigating BO among ECDs in Nigeria.MethodUsing purposive sampling method, two sessions of focus group discussions (FGDs) involving 14 ECDs (key informants) holding key leadership positions and who were delegates of other ECDs in Nigeria were conducted to explore their experiences on psychological issues among ECDs. Data collected were transcribed and analyzed thematically.ResultsBO is an issue of serious concern among ECDs in Nigeria. The causes of BO are diverse, some of which include low staff strength, prolonged work hours, wrong counseling, lack of job description and specification, and abuse of powers by trainers. In order to mitigate the issue of BO among ECDs, the respondents recommended that work policy review, medical workforce strengthening, stakeholder dialog on ECDs’ welfare, regular psychological review of ECDs, and provision of free yearly medicals need to be looked into. Conclusion: Our findings revealed that the participants considered BO issues among ECDs to be common, and it affected their performance and the overall quality of care in Nigeria health system. Based on our findings, there is an urgent need to mitigate the problem of emotional exhaustion among ECDs in Nigeria.

Random Regret Minimization

In this study, discrete choice models that combine different behavioural rules are estimated to study the visitors’ preferences in relation to their travel mode choices to access a national park. Using a revealed preference survey conducted on visitors of Teide National Park (Tenerife, Spain), we present a hybrid model specification—with random parameters—in which we assume that some attributes are evaluated by the individuals under conventional random utility maximization (RUM) rules, whereas others are evaluated under random regret minimization (RRM) rules. We then compare the results obtained using exclusively a conventional RUM approach to those obtained using both RUM and RRM approaches, derive monetary valuations of the different components of travel time and calculate direct elasticity measures. Our results provide useful instruments to evaluate policies that promote the use of more sustainable modes of transport in natural sites. Such policies should be considered as priorities in many national parks, where negative transport externalities such as traffic congestion, pollution, noise and accidents are causing problems that jeopardize not only the sustainability of the sites, but also the quality of the visit.
