Abstract. We present Nemo-Nordic, a Baltic & North Sea model based on the NEMO ocean engine. Surrounded by highly industrialised countries, the Baltic and North seas, and their assets associated with shipping, fishing and tourism; are vulnerable to anthropogenic pressure and climate change. Ocean models providing reliable forecasts, and enabling climatic studies, are important tools for the shipping infrastructure and to get a better understanding of effects of climate change on the marine ecosystems. Nemo-Nordic is intended to come as a tool for both short term and long term simulations, and to be used for ocean forecasting as well as process and climatic studies. Here, the scientific and technical choices within Nemo-Nordic are introduced, and the reasons behind the design of the model and its domain, and the inclusions of the two seas, are explained. The model's ability to represent barotropic and baroclinic dynamics, as well as the vertical structure of the water column, is presented. Biases are shown and discussed. The short term capabilities of the model are presented, and especially its capabilities to represent sea level on an hourly timescale with a high degree of accuracy. We also show that the model can represent longer time scale, with a focus on the Major Baltic Inflows and the variability of deep water salinity in the Baltic Sea.

<p>Tahun 2016, pemerintah mengeluarkan kembali kebijakan <em>Tax</em> <em>Amnesty </em>yang dituangkan dalam Undang-Undang Nomor 11 Tahun 2016 tentang Pengampunan Pajak. Pengampunan Pajak (<em>Tax</em> <em>Amnesty)</em> ini diharapkan dapat meningkatkan penerimaan pajak dalam jangka pendek melalui pembayaran uang tebusan, meningkatkan penerimaan pajak dalam jangka panjang melalui perluasan basis data pemajakan, meningkatkan kepatuhan Wajib Pajak, transisi ke sistem perpajakan baru yang lebih kuat dan adil, dan mendorong rekonsiliasi perpajakan nasional. Sehubungan dengan hal tersebut, untuk mengetahui apakah program <em>Tax</em> <em>Amnesty</em> Indonesia Tahun 2016 berhasil atau tidak, khususnya dalam meningkatkan kepatuhan wajib pajak, maka perlu dilakukan penelitian tentang : “Implikasi Penerapan Undang-Undang Nomor 11 Tahun 2016 tentang Pengampunan Pajak (<em>Tax</em> <em>Amnesty</em>) dalam Meningkatkan Kepatuhan Wajib Pajak”. Adapun permasalahan yang akan dibahas adalah bagaimana implikasi penerapan Undang-Undang Nomor 11 Tahun 2016 tentang Pengampunan Pajak<em> (Tax</em> <em>Amnesty)</em> dalam meningkatkan kepatuhan Wajib Pajak ? Berdasarkan implikasi tersebut, maka bagaimana sebaiknya pengaturan perpajakan yang akan datang ? Berdasarkan permasalahan tersebut jenis penelitian ini adalah yuridis normatif yang akan dikaji dengan pendekatan perundang-undangan, spesifikasi penelitiannya diskriptif analitis, data yang dipergunakan data sekunder, yang dianalisis secara kualitatif. Hasil penelitian menunjukkan bahwa implikasi penerapan Undang-Undang Nomor 11 Tahun 2016 tentang Pengampunan Pajak<em> (Tax</em> <em>Amnesty)</em> dapat meningkatkan kepatuhan Wajib Pajak, dan berdasarkan implikasi tersebut SE Dirjen Pajak No. SE - 06/PJ/2017 seharusnya tidak hanya untuk tahun pajak 2017 saja, tetapi juga untuk tahun-tahun yang akan datang. Di samping itu perlu ada peraturan yang mengatur tentang pengawasan terhadap pelaksanaan hak Wajib Pajak.</p><pre>In 2016, the government re-issue the Tax Amnesty policy as outlined in Law Number 11 Year 2016 on Tax Amnesty. The Tax Amnesty is expected to increase tax revenue in the short term through ransom payments, increase tax revenues over the long term through the expansion of taxation databases, increase taxpayer compliance, transition to a stronger and more just tax system, and encourage national tax reconciliation. In relation to this matter, to find out whether the program of Tax Amnesty Indonesia Year 2016 succeed or not, especially in increasing taxpayer compliance, it is necessary to do research on: "Implications Implementation of Law Number 11 Year 2016 on Tax Amnesty in Improving Taxpayer Compliance ". The problem to be discussed is how the implications of the implementation of Law Number 11 Year 2016 on Tax Amendment (Tax Amnesty) in improving taxpayer compliance? Based on these implications, then how should the taxation arrangements to come? Based on the problem, this type of research is normative juridical which will be studied with the approach of legislation, the analytical descriptive research specification, the data used secondary data, which analyzed qualitatively. The result of the research shows that the implication of the implementation of Law Number 11 Year 2016 on Tax Amnesty can improve Taxpayer compliance, and based on the implication of SE Dirjen Pajak No. SE - 06 / PJ / 2017 should not only be for the fiscal year 2017 alone, but also for the years to come. In addition, there should be a regulation that regulates the supervision of the implementation of taxpayers' rights.</pre>

A burgeoning “Climate-Economy” literature has uncovered many effects of changes in temperature and precipitation on economic activity, but has made considerably less progress in modeling the effects of other associated phenomena, like natural disasters. We develop new, objective data on floods, focusing on Bangladesh. We show that rainfall and self-reported exposure are weak proxies for true flood exposure. These data allow us to study adaptation, giving accurate measures of both long-term averages and short term variation in exposure. This is important in studying climate change impacts, as people will not only experience new exposures, but also experience them differently.

The cycle of carbon is essential to the maintenance of life, to climate, and to the composition of the atmosphere and oceans. What is normally thought of as the “carbon cycle” is the transfer of carbon between the atmosphere, the oceans, and life. This is not the subject of interest of this book. To understand this apparently confusing statement, it is necessary to separate the carbon cycle into two cycles: the short-term cycle and the long-term cycle. The “carbon cycle,” as most people understand it, is represented in figure 1.1. Carbon dioxide is taken up via photosynthesis by green plants on the continents or phytoplankton in the ocean. On land carbon is transferred to soils by the dropping of leaves, root growth, and respiration, the death of plants, and the development of soil biota. Land herbivores eat the plants, and carnivores eat the herbivores. In the oceans the phytoplankton are eaten by zooplankton that are in turn eaten by larger and larger organisms. The plants, plankton, and animals respire CO2. Upon death the plants and animals are decomposed by microorganisms with the ultimate production of CO2. Carbon dioxide is exchanged between the oceans and atmosphere, and dissolved organic matter is carried in solution by rivers from soils to the sea. This all constitutes the shortterm carbon cycle. The word “short-term” is used because the characteristic times for transferring carbon between reservoirs range from days to tens of thousands of years. Because the earth is more than four billion years old, this is short on a geological time scale. As the short-term cycle proceeds, concentrations of the two principal atmospheric gases, CO2 and CH4, can change as a result of perturbations of the cycle. Because these two are both greenhouse gases—in other words, they adsorb outgoing infrared radiation from the earth surface—changes in their concentrations can involve global warming and cooling over centuries and many millennia. Such changes have accompanied global climate change over the Quaternary period (past 2 million years), although other factors, such as variations in the receipt of solar radiation due to changes in characteristics of the earth’s orbit, have also contributed to climate change.

Diffusion of responsibility refers to the problem that when something is everyone’s job, it in effect ends up being nobody’s job. This explains why many collective problems arise. People face perverse incentives to free ride on others’ actions and not to do their part. As a result, agents often think in short-term rather than long-term ways. Problems such as climate change can be modeled as instances of the tragedy of the commons, one form of a collective action problem that arises due to perverse incentives created by the diffusion of responsibility.

AbstractAs the level of understanding about climate change has increased, the term “climate security” has been increasingly used in the rapidly growing literature on this subject. Although Japan has officially acknowledged the importance of tackling climate change, discussion of climate security has been almost nonexistent among Japanese governmental officials, politicians, and academics. Our aim was to trace discourses related to climate security in Japan to determine why so little exists in Japan and whether or not such discourse could suggest new areas for consideration to more comprehensively respond to the climate change problem. Because of different interpretations and uses of the term “climate security” in the existing literature, we first categorized existing approaches to climate security into four types and used this categorization to examine Japan’s discourse from these perspectives. Two of the approaches, namely “long-term irreversible planetary changes” and “short-term abrupt risks to individuals”, had been considered in Japan previously but without specific reference to the term climate security. The other two, “cause of conflict and violence” and “impacts to military and defense organizations”, however, had not been used and need to be included in discussions of climate change in Japan. Some of the topics not discussed in Japan include indirect economic losses of Japanese industries via supply chains, loss of Japan’s exclusive economic zone due to sea-level rise, and the potential inflow of refugees resulting from extreme weather patterns outside of Japan.

This paper investigates analogies in the dynamics of Covid-19 pandemic and climate change. A comparison of their common features (such as nonlinearity and inertia) and differences helps us to achieve a correct scientific perception of both situations, increasing the chances of actions for their solutions. Besides, applying to both the risk equation provides different angles to analyse them, something that may result useful especially at the policy level. It shows that not only short-term interventions are needed, but also long-term strategies involving some structural changes. More specifically, it also shows that, even if climate change is probably more critical and long-lasting than the Covid-19 crisis, we still have, at least currently, more options for reducing its related risk.

Even though conflict is increasingly finding its way into school settings, there is evidence that school leaders do not view themselves as being adequately equipped to meet the growing challenges. Training on short-term approaches to dealing with immediate issues may be available to practitioners through professional development offerings, but there is more involved in successfully and sustainably dealing with conflict than getting through a tense moment. School leaders need to be able to understand the causes and complexities—as well as navigate time elements—associated with ongoing conflict that can take place at the personal as well as organizational levels. Beyond understanding these concepts, administrators themselves need to increase the capacity of their staff and their organizations to assist in their development. In addition to learning how to recognize patterns and underlying causes advancing adversity, administrators would do well to invest in long-term conflict diminishing approaches such as building trust and improving interpersonal and organizational capacity as ways to increase credibility within and outside of the school itself. Finding people who can think critically and work adaptively to solve problems could prove to be a real advantage for educational leaders who strive to reduce the stress of the workplace and create a more collegial climate within the schools they serve. Building trust and the ability to “come through” capably for others even in tough situations increases the credibility of leaders. Leading through conflict with this credibility in turn helps to sustain a positive climate in schools.
