Abstract. The Chersky seismic belt represents a zone of deformation between the North American and Eurasian plates in northeast Russia. The belt extends from the Laptev Sea into the Chersky Range where it splits into two branches. One branch extends to Kamchatka and the Aleutian-Kurile Junction, while the other branch extends south towards Sakhalin Island. Focal mechanisms indicate a change from extension to transpression in the northern Verkhoyansk Range and generally left-lateral transpression in the Chersky Range extending to northern Kamchatka. The few focal mechanisms on the second branch suggest right-lateral transpression. A large number of faults, sub-parallel to the seismicity and presumed to be strike-slip, are visible in satellite imagery and topographic maps and are also associated with seismically generated landslides. These data support a model in which the Sea of Okhotsk forms the core of a separate Okhotsk microplate surrounded by diffuse boundaries on the north and west. Microseismicity in continental northeast Russia is most heavily concentrated within and between the fault systems along the northern boundary of the proposed Okhotsk plate and indicates a high level of deformation. The sense of slip on the faults (both from focal mechanisms and geology) are also generally consistent with the extrusion of the Okhotsk plate to the southeast as it is compressed between its larger neighbors. The northernmost part of the Okhotsk plate may be decoupled to some degree from the more stable central Sea of Okhotsk.

For a long time, the north-western part of the East European Craton, specifically the East Baltic region (EBR), was considered an aseismic territory. Historical earthquakes did take place in the EBR, but they occurred rarely and could not always be associated with tectonic conditions. The attitude towards seismicity of the region began to change after the Osmussaar earthquake on 25 October 1976 (M=4.7) and especially after the Kaliningrad earthquakes on 21 September 2004 (Mw = 5.0; Mw = 5.2). In this study, the seismicity of the EBR was generalized over 13 years after the Kaliningrad earthquakes on the basis of Scandinavian and our own data. In several cases focal mechanisms were solved for weak earthquakes. The study showed a tendency of seismic activity to decrease from northwest to southeast, a predominant concentration of earthquakes sources in the East Baltic coastal zone, and the activation of Ladoga-Bothnia, Vyborg, Olaine-Inčukalns, Võrtsjärv zones. The main problems are associated with a rare seismic network, high level of ambient seismic noise, and a large number of man-made sources.

The location of Igbomina in the middle belt of Nigeria and as a frontier Yoruba region opened it to the influence from powerful, competing states of Oyo, Nupe, Fulani, and Ibadan. The expansion of the Oyo Empire in the 16th century, which was accompanied by the large migration of Yoruba northward, led to frequent military aggression on the northern boundary with the Nupe. This paper examines military aggressions in the Igbomina area of north central Yorubaland. Military threat or warfare had initiated various responses in Igbomina, as evident in community aggregation, building of fortifications, production of weapons, and settlement abandonment. The high level of military aggression in Igbomina had also acted as an instrument of socio-political changes in the area as seen in increased centralized control and hierarchy. Oral-historical sources, archaeological survey and excavation form the core of this examination of military aggression in Igbomina.

“The real treasure is in the minds of our children, and all we have to do is extract it.” Her Majesty Queen Rania Al Abdullah writes in website Queen Rania Foundation For Education And Development www.qrf.org/en. Rania Al Yassin was born on August 31, 1970. She obtained her Bachelor’s degree in Business Administration from the American University of Cairo in 1991. She applied this, first, to a banking career in Jordan and, later, to the information technology sector. After marrying Prince Abdullah bin Al Hussein on June 10, 1993, they went on to have four children: Prince Hussein, Princess Iman, Princess Salma, and Prince Hashem. In addition to being a wife and mother, Queen Rania works hard to lift the lives of Jordanians by supporting their endeavours and helping to create new opportunities for them. Locally, she is committed to breathe new life into the public education system; empower communities and women especially through microfinance initiatives; protect children and families; and drive innovation, technology and entrepreneurship, especially amongst young people. Internationally, Queen Rania is an advocate for tolerance, compassion and bridge building between people of all cultures and backgrounds. Her efforts to simultaneously challenge stereotypes of Arabs and Muslims, and promote greater understanding and acceptance between people of all faiths and cultures, have won her global recognition. Her Majesty’s passion is education. She believes that every Jordanian girl and boy, and all children, should have access not only to stimulating classrooms and modern curricula, but inspiring teachers and technology that can connect Jordan’s children to the world and the world to Jordan’s children. Her efforts in the education sector complement the work of the Ministry of Education through initiatives such as the Jordan Education Initiative, the Queen Rania Teachers Academy, Madrasati, Edraak and others. To realize these and so much more, Queen Rania has encouraged private sector partners to drive improvements and strengthen the foundations of Jordan’s education system. Queen Rania is also a global voice for access to quality education for children around the world. In 2009, Her Majesty championed the 1 Goal campaign for education; she is Honorary Chair of the UN Girl’s Education Initiatives and has advocated access to education in forums and gatherings around the world. Her work and her efforts to improve the learning opportunities for children have been recognized at the highest levels, nationally, regionally and internationally. Additionally, through her position on their boards, Her Majesty contributes to the work of the United Nations Fund and the World Economic Forum. She is the Eminent Advocate for UNICEF; and she was part of the UN appointed High Level Panel who advised on the shape and content of the Sustainable Development Goals which aim to improve the lives of millions of people before 2030. In recognition of her work, Her Majesty has humbly accepted many awards, locally, regionally and globally. These include the Walther Rathenau Award from the Walther RathenauInstitut in Germany for her efforts to greater peace and understanding; the James C. Morgan Global Humanitarian Award from Tech Awards, USA; the Arab Knight of Giving Award from Arab Giving Forum, UAE; the North South Prize by the North South Prize, Portugal; as well as the YouTube Visionary Award. Her Majesty authored several books primarily for children including the Sandwich Swap, which was inspired by her own childhood experiences.

This chapter deals with the dependent variable of the study: consent. It analyses workplace consent in Russia and China using three indicators that refer to the core requirements of the production systems in automotive companies regarding employee behavior: first, standardized work; and second, compliance with expectations in terms of flexibility, cooperation, and a commitment to improving processes. The third indicator of consent (or the lack of it) is the absence or presence of open criticism, resistance, and labor disputes. The chapter reveals significant and unexpected differences between the Chinese and Russian sites on all three indicators. While the Chinese factories exhibit (with some variance between the companies), a relatively high level of consent, the Russian plants have problems with standardized work, the acceptance of performance expectations, and to some extent with labor disputes.

AbstractIn the North Atlantic, euphausiids (krill) form a major link between primary production and predators including commercially exploited fish. This basin is warming very rapidly, with species expected to shift northwards following their thermal tolerances. Here we show, however, that there has been a 50% decline in surface krill abundance over the last 60 years that occurred in situ, with no associated range shift. While we relate these changes to the warming climate, our study is the first to document an in situ squeeze on living space within this system. The warmer isotherms are shifting measurably northwards but cooler isotherms have remained relatively static, stalled by the subpolar fronts in the NW Atlantic. Consequently the two temperatures defining the core of krill distribution (7–13 °C) were 8° of latitude apart 60 years ago but are presently only 4° apart. Over the 60 year period the core latitudinal distribution of euphausiids has remained relatively stable so a ‘habitat squeeze’, with loss of 4° of latitude in living space, could explain the decline in krill. This highlights that, as the temperature warms, not all species can track isotherms and shift northward at the same rate with both losers and winners emerging under the ‘Atlantification’ of the sub-Arctic.

ABSTRACTIn two experiments over 2 years, 57 North Country Cheviot and 82 South Country Cheviot hill ewes were differentially group-fed indoors over a 2-month period to achieve either good or moderate body con- dition. Over 5 weeks prior to mating, ewes in good condition were brought down in condition by restricted feeding and ewes in mod- erate condition were raised in condition by a high level of feeding. The ewes were thus in moderately-good condition at mating. After mating, ewes were maintained in this condition until killed either on return to service or at 29 ± 8 days for counts of corpora lutea and viable embryos.Ovulation rate in each breed was positively related to the level of pre-mating food intake at the condition level studied. Embryo mortality, as ova loss, was not influenced overall by the level of pre-mating food intake but loss of multiple-shed ova was greater than that of single-shed ova in ewes which had been on restricted feeding before mating. Although a greater proportion of ewes in the North Country Cheviot breed were not pregnant at slaughter, this could not be identified as a breed difference since the breeds were studied in different years.

Temperature records from slations on the west roast of the Antarctic Peninsula show a very high level of interannual variability and, over the last 50 years, larger warming trends than are seen elsewhere in Antarctica. in this paper we investigate the role of atmospheric circulation variability and sea-ice extent variations in driving these changes. Owing to a lack of independent data, the reliability of Antarctic atmospheric analyses produced in the 1950s and 1960s cannot be readily established, but examination of the available data suggests that there has been an increase in the northerly component of the circulation over the Peninsula since the late 1950s. Few observations of sea-ice extent are available prior to 1973, but the limited data available indicate that the ice edge to the west of the Peninsula lay to the north of recently observed extremes during the very cold conditions prevailing in the late 1950s. The ultimate cause of the atmospheric-circulation changes remains to be determined and may lie outside the Antarctic region.

High rates of desertion and surrender during the battles in North Africa in the summer of 1942 were a major factor in Eighth Army’s poor combat performance. At the time, some suggested that these problems were symptomatic of a lack of courage or even of cowardice. There are two broad strands to the conceptualization of courage and cowardice. One focuses on the willingness of the person to fight; the other puts emphasis on how actions express an individual’s ability to cope with fear. Whichever conceptualization is used, high morale motivates the soldier to fight and shields the ordinary recruit from his fear, preventing it from overcoming him in battle. Where morale fails, the soldier is left demotivated and burdened with his terror and, therefore, and is therefore prone to desertion or surrender. Because it is extremely difficult to maintain morale at a continuously high level in an environment governed by chance and managed by humans, all soldiers can find themselves in situations where their actions may be judged as cowardly. Alternatively, if they are properly motivated to fight and prepared by the state and military to deal with the unavoidable fear of combat, all soldiers can be labelled courageous. Accordingly, emotive terms should be avoided when attempting to describe rationally explainable outcomes. The undoubtedly negative connotations attached to cowardice in battle and the positive ones attached to courage are, therefore, arguably unhelpful in understanding Eighth Army’s performance in the summer of 1942 and the human dimension in warfare more generally.
