This book describes the interaction of the main biogeochemical cycles of the Earth and the physics of climate. It takes the perspective of Earth as an integrated system and provides examples of both changes in the current climate and those in the geological past. The first three chapters offer a general introduction to the context of the book, outlining the climate system as a complex interplay between biogeochemistry and physics and describing the tools available for understanding climate: observations and models. These chapters describe the basics of the system, the rates and magnitudes and the crucial aspects of biogeochemical cycles needed to understand their functioning. The second part of the book consists of four chapters that describe the physics required to understand the interaction of the climate with biogeochemistry and change. These chapters describe the physics of radiation, and that of the atmosphere, ocean circulation and thermodynamics. The interaction of aerosols with radiation and clouds is addressed in an additional chapter. The third part of the book deals with Earth’s (bio)geochemical cycles. These chapters focus on the stocks and fluxes of the main reservoirs of Earth’s biogeochemical cycles—atmosphere, land and ocean—and their role in the cycles of carbon, oxygen, nitrogen, iron, phosphorus, oxygen, sulphur and water, as well as their interactions with climate. The final two chapters describe possible mitigation and adaptation actions, in relation to recent climate agreements, but always with an emphasis on the biogeochemical aspects.

Global Positioning System (GPS) and strap-down inertial navigation system (SINS) are recognized as highly complementary and widely employed in the community. The GPS has the advantage of providing precise navigation solutions without divergence, but the GPS signals might be blocked and attenuated. The SINS is a totally self-contained navigation system which is hardly disturbed. The GPS/SINS integration system could utilize the advantages of both the GPS and SINS and provide more reliable navigation solutions. According to the data fusion strategies, the GPS/SINS integrated system could be divided into three different modes: loose, tight, and ultratight integration (LI, TI, and UTC). In the loose integration mode, position and velocity difference from the GPS and SINS are employed to compose measurement vector, in which the vector dimension has nothing to do with the amount of the available satellites. However, in the tight and ultratight modes, difference of pseudoranges and pseudorange rates from the GPS and SINS are employed to compose the measurement vector, in which the measurement vector dimension increases with the amount of available satellites. In addition, compared with the loose integration mode, clock bias and drift are included in the integration state model. The two characteristics magnify the computation load of the tight and ultratight modes. In this paper, a new efficient filter model was proposed and evaluated. Two schemes were included in this design for reducing the computation load. Firstly, a difference between pseudorange measurements was determined, by which clock bias and drift were excluded from the integration state model. This step reduced the dimension of the state vector. Secondly, the integration filter was divided into two subfilters: pseudorange subfilter and pseudorange rate subfilter. A federated filter was utilized to estimate the state errors optimally. In the second step, the two subfilters could run in parallel and the measurement vector was divided into two subvectors with lower dimension. A simulation implemented in MATLAB software was conducted to evaluate the performance of the new efficient integration method in UTC. The simulation results showed that the method could reduce the computation load with the navigation solutions almost unchanged.

In a previous paper, we showed that Earth-type habitable planets around 47 UMa are in principle possible if a distinct set of conditions is warranted. These conditions include that the Earth-type planets have successfully formed and are orbitally stable and, in addition, that the 47 UMa star–planet system is relatively young ([lsim ]6 Gyr). We now extend this study by considering Earth-like planets with different land/ocean coverages. This study is again based on the so-called integrated system approach, which describes the photosynthetic biomass production taking into account a variety of climatological, biogeochemical and geodynamical processes. This approach implies a special characterization of the habitable zone defined for a distinct type of planet. We show that the likelihood of finding a habitable Earth-like planet on a stable orbit around 47 UMa critically depends on the percentage of the planetary land/ocean coverage. The likelihood is significantly increased for planets with a very high percentage of ocean surface (‘water worlds’).

Rhetorical Violence

The task of identifying a single rationale for the violence on display in the book of Jeremiah may end with a coherent answer, but perhaps not a satisfactory one. That violence serves a reforming purpose seems satisfactory to theological readers in search of theodicy, as well trauma analyses that find the violence problematic but understandable. Other interpreters of Jeremiah, such as feminists and postcolonialists, struggle with the gratuitous and seemingly arbitrary nature of the violence. While not an attempt to rationalize the violence, this chapter engages the arbitrariness of the violence through a systematic analysis of four targets of violence in the book of Jeremiah: the prophet, the feminized Israel/Judah as adulterous wife, foreign nations, and the earth. By distinguishing these separate targets, the chapter examines how gender, sexuality, nationality, and speciesism intersect in the enactment of the rhetorical violence in the book. These delineations also set the stage for a central claim of the chapter, that of exceptional violence. Building upon Carl Schmidt’s notion that exceptional violence stems from exceptional vulnerability that requires the state of exception to use unrestrained violence, the chapter considers how the violence as narrated in Jeremiah not only performs this exceptionalism but also has exceptions. By examining who/what dies from the violence in the book, the chapter points out how the politics of death is played out upon different targets.

Compared to other groups of organisms, plants require distinctive approaches in their conservation because of their keystone roles in ecosystems and economies. The state of the whole plant cover of the Earth should be of concern to conservationists – for its capacity to ensure the survival of plant species, deliver ecosystem services (locally to globally) and provide produce from plants in ecologically sustainable ways. The primary targets of attention in ecosystem-based plant conservation are the relationships between people and plants, as relevant to every locality, rather than the species-centric approach of conventional plant conservation. Moving plant conservation to an ecosystem-based approach will require the development of training programmes for field practitioners and of information systems for their use.

And so Missouri has fallen, that great State! Certain of her children have joined the lynchers, and the smirch is upon the rest of us. That handful of her children have given us a character and labeled us with a name; and to the dwellers in the four quarters of the earth we are “lynchers,” now, and ever shall be. For the world will not stop and think – it never does, it is not its way; its way is to generalize from a single sample. It will not say “Those Missourians have been busy eighty years in building an honorable good name for themselves; these hundred lynchers down in the corner of the State are not real Missourians, they are bastards.” No, that truth will not enter its mind; it will generalize from the one or two misleading samples and say “The Missourians are lynchers.” It has no reflection, no logic, no sense of proportion. With it, figures go for nothing; to it, figures reveal nothing, it cannot reason upon them rationally; it is Brother J. J. infinitely multiplied; it would say, with him, that China is being swiftly and surely Christianized, since 9 Chinese Christians are being made every day; and it would fail, with him, to notice that the fact that 33,000 pagans are born there every day, damages the argument. It would J-J Missouri, and say “There are a hundred lynchers there, therefore the Missourians are lynchers;” the considerable fact that there are two and a half million Missourians who are not lynchers would not affect their verdict any more than it would affect Bro. J. J.'s.

with carrying out the decentralization reform public administration mechanisms play an important role in ensuring the comprehensive development of rural areas. Expanding the use of such mechanisms in the sphere of cooperation on the state level will facilitate development and support of small entrepreneurial forms, common use of material and technical basis, emerging new working places, building social infrastructure and engineering communications, providing qualitative services to citizens and preserving rural settlements. The objective of the article is to identify constituents of the comprehensive mechanism of public administration for development of service cooperation of rural areas in Ukraine and to integrate them into a coherent system which would facilitate realization of the state strategies and programmes to achieve the Sustainable Development Goals. The object of the research is a comprehensive mechanism of public administration for development of service cooperation. Research methodology is grounded upon the use of general scientific knowledge methods, in particular, logical and semantic, induction and deduction for formulating definitions, systemic and situational analysis for characterizing constituents of a comprehensive mechanism and identifying their interrelations. Based on the systemic approach it has been defined that comprehensive mechanism is an integrated system which combines interrelated and dependable functioning of legislative, institutional, organisational and economic, financial and credit, information and communication as well as staffing mechanisms in the sphere of developing cooperative movement in the rural localities. It is proved that every mechanism influences its particular direction and is formed at the international, national, regional and local levels based on cooperative values and generalized system of principles. Special attention is paid to the research of international and national legislation to generalize the system of principles of cooperation, intermunicipal cooperation, public authorities and public associations’ functioning, upon which the comprehensive mechanism for public administration of service cooperation development in rural areas of Ukraine is based.
