African White-backed Vultures were recently uplisted to ‘Critically Endangered’ by IUCN due to declines across their range. Poisoning is widely accepted as the major reason for these declines. Botswana supports a high number of this species (breeding pairs > c.1,200), but as yet no published information exists on their breeding success in the country. However, mass poisonings within Botswana and neighbouring countries have killed thousands of White-backed Vultures in recent years. We therefore expected that nesting numbers may have declined in this region if these poisoning events killed local breeding birds. We used information from aerial surveys conducted between 2006 and 2017 in Khwai and Linyanti, two important breeding areas for this species in north-central Botswana, to determine if there was any change in nesting numbers and breeding success of White-backed Vultures. Results showed an overall 53.5% decline in nesting numbers, with a greater decline in Linyanti than in Khwai. In both areas, breeding success was significantly lower in 2017 than it was 10 ten years earlier. We recommend that similar repeat surveys are continued to provide greater confidence in the trends of both nesting numbers and breeding performance. Population viability analysis suggested that if the productivity levels detected in 2017 were a true indication of current productivity levels for this population, and if recent high poisoning rates continue, this population could be extirpated from the area in the next 13 years.

The Mongolian People's Republic (MPR) became the focus of intense competition between the Soviet Union and Japan in the 1930s, when it was more commonly known as Outer Mongolia. The Soviet Union viewed the MPR as an ideological and strategic ally, and was determined to defend that state against the increasingly adventurist actions of the Japanese military based in northern China. Japanese ambitions to solve the so-called ‘Manmo’ (Manchuria-Mongolia) problem led the Soviets to initiate ever-closer links with the MPR, culminating in the 1936 pact of mutual assistance which was intended to constrain Japanese pressure. Using unpublished Japanese materials as well as Russian and Mongolian sources, this article demonstrates how the Soviet leadership increasingly viewed the MPR as strategically crucial to the defence of the Soviet Far East.

Glyphosate is used in the transition zone to control annual bluegrass in fully dormant warm-season grasses. A suspected resistant (R) biotype of annual bluegrass was identified on a golf course in South Carolina after at least 10 consecutive years of glyphosate application. Greenhouse bioassays revealed the R biotype was 4.4-fold resistant to glyphosate compared with a standard susceptible (S) biotype. Further studies were conducted to investigate the mechanism conferring glyphosate resistance in the R biotype. Leaf discs of both biotypes accumulated shikimate in response to increasing glyphosate concentration, but the glyphosate concentration resulting in 50% EPSP synthase inhibition as a result of shikimate accumulation (I50) was 4.2-fold higher in the R biotype compared with the S biotype. At the whole plant level, similar levels of shikimate accumulation were observed between biotypes at 6 and 24 h after treatment (HAT) with glyphosate, but greater shikimate accumulation occurred in the S biotype at 72, 120, and 168 HAT. Shikimate levels decreased in the R biotype after 72 HAT. There were no differences in 14C-glyphosate absorption between biotypes. However, more 14C-glyphosate translocated out of the treated leaf in the R biotype and into root tissues over time compared with the S biotype. Partial sequencing of the EPSP synthase gene revealed a point mutation that resulted in an Ala substitution at Pro106. Although other mechanisms may contribute to glyphosate resistance, these results confirm a Pro106 to Ala substitution is associated with resistance to glyphosate in the R annual bluegrass biotype.

Executive functions are highly sensitive to the effects of aging and other conditions affecting frontal lobe function. Yet there are few validated interventions specifically designed to address executive functions, and, to our knowledge, none validated in a healthy aging sample. As part of a large-scale cognitive rehabilitation randomized trial in 49 healthy older adults, a modified Goal Management Training program was included to address the real-life deficits caused by executive dysfunction. This program emphasized periodic suspension of ongoing activity to establish goal hierarchies and monitor behavioral output. Tabletop simulated real-life tasks (SRLTs) were developed to measure the processes targeted by this intervention. Participants were randomized to two groups, one of which received the intervention immediately and the other of which was wait-listed prior to rehabilitation. Results indicated improvements in SRLT performance and self-rated executive deficits coinciding with the training in both groups. These gains were maintained at long-term follow-up. Future research will assess the specificity of these effects in patient groups (JINS, 2007, 13, 143–152.)

This article analyses the nature of contemporary Hong Kong–Japan relations in their economic, political and cultural dimensions, setting the relationship within the broader context of Sino-Japanese relations, concerns about identity and nationalism within Hong Kong, and changing Japanese commercial priorities. While the commercial and popular cultural ties between Japan and Hong Kong remain dominant, since the mid-1990s political issues have become more visible in Hong Kong–Japan relations. Changing moods within Hong Kong about the handover and, after 1997, about the nature of the redefined relationship with China have had an important influence on the political economy of Hong Kong–Japan relations.

This study provides the first prospective evaluation of the course and predictors of children's involvement with fire over a 2-year period in 268 nonpatient and patient children (ages 6–13 yrs). Selected predictor variables obtained at initial (intake) assessment, which included fire-specific and general psychosocial measures, were examined in each sample using hierarchical logistic regression. Both samples reported heightened involvement in matchplay and firesetting at follow-up, though the frequency of each behavior was nearly four times higher in patients than in nonpatients. Fifty per cent and 59% of the initial firesetters in the nonpatient and patient samples, respectively, became recidivists. In the nonpatient sample, the child's initial involvement in firesetting and level of covert antisocial behavior were the only psychosocial predictors of follow-up firesetting that added incremental variance beyond demographics. In the patient sample, the child's initial involvement in fire-related acts and level of covert antisocial behavior were the only predictors of follow-up firesetting beyond any initial involvement in matchplay. The findings highlight somewhat different risk factors for subsequent firesetting in nonpatient and patient children, especially prior firesetting and matchplay, respectively, and bear implications for the prevention of firesetting recidivism.

The 3-km thick Neogene Siwalik Group (Himalayan foredeep in northern Pakistan) and the 2-km thick Paleogene Fort Union/Willwood Formations (Bighorn Basin, Wyoming) both preserve long records of fluvial deposition adjacent to rising mountain belts. Depositional environments and associated habitats change with spatially varying physiography and deposition by river systems that may differ greatly in size, sediment loads, depositional rates, drainage of adjacent floodplains, and taphonomy of organic remains. At times, some environments may not be preserved; for example, avulsion of channels to low areas removes more deposits of channel-distal environments as avulsions increase relative to net sediment aggradation rates. Recognition of such large-scale biases is important because they represent time scales over which long term paleoecological change is reconstructed, and requires knowledge of how drainage systems changed in time and space within these evolving basins.
The Siwalik Group was deposited by large rivers that filled a basin extending at least 1000 km along its axis and 150–250 km away from the mountain front. Despite the scale of these rivers relative to Siwalik exposures, transitions between different fluvial systems have been recognized. For example, a 1-km thick sequence bridging the boundary between Chinji and Nagri formations records displacement of a smaller river system (width < 2 km; depth 5-10 m; discharge 1000-1500 m3/s) by a larger system (width <5 km; depth 15-30 m; discharge at least 5,000-10,000 m3/s), with an associated upsection increase (30 to 70%) in the proportion of channel sandstones, increased mean sediment accumulation rates (150 to 300 m/my), decrease in poorly drained floodplain deposits and well developed paleosols, marked decrease in abundance of faunal remains, and a major change in faunal composition. Stratigraphically higher (Dhok Pathan Fm.), there is a lateral transition between deposits of dissimilar, coeval river systems with corresponding differences in local paleoenvironments and vertebrate taphonomy. Although upsection changes in environments and vertebrate faunas may generally reflect extrabasinal controls such as tectonism and climate change, our studies emphasize the importance of recognizing deposits from different contemporaneous river systems before inferring such large-scale controls on paleoenvironmental change through time.
The Bighorn Basin is an intermountain foreland basin extending 200 km along its axis and about 80 km across. A large portion of this basin is exposed, and thus it is possible to reconstruct the distribution of river systems and the spatial paleoenvironments in more detail than in the Siwaliks. The Bighorn Basin was traversed along its axis by an early Eocene, north-south flowing river that was joined by smaller rivers flowing transverse to the axis. The proportion of channel sandstones decreases upsection (50 to 25%) from the Fort Union to the Willwood Fm. The proportion of channel sandstones and the abundance of well developed paleosols decrease with increasing net sediment aggradation rates. Although channel deposits are concentrated along the basin axis in a more complex way in some stratigraphic intervals, it is unclear to what extent these changes reflect deposition by different rivers versus extrinsically controlled changes within individual river systems.

In the past decade there has been a rapid diversification of services provided for patients with chronic psychiatric illnesses. Although these services are thought to be beneficial for those who use them, there has been little in the way of objective evaluation. As new services begin to compete for the limited resources available, it has been recommended that they should demonstrate their effectiveness. This paper reports a small pilot study on the value of an arts based service known as START (Bridges & Brown, 1989) which won a BBC ‘It's My City’ competition in 1989. It has been a popular component of the rehabilitation services of the Department of Psychiatry, Manchester Royal Infirmary since its inception in 1986.

While the developments leading up to the signature of the Soviet—Japanese Neutrality Pact in April 1941 have received considerable attention from scholars, the antecedents of this pact, the discussions between Japan and Soviet Russia over non-aggression or neutrality agreements from the mid-1920s onwards, are less widely known. The most significant of the earlier initiatives came in December 1931, when Soviet Foreign Commissar, Maxim Litvinov, proposed a pact of non-aggression to the Japanese Foreign Minister designate, Yoshizawa Kenkichi. Subsequently, at the International Military Tribunal for the Far East, a Soviet legal expert was to argue that the Japanese refusal to accept this proposal was proof of their aggressive plans for war on the Soviet Union.
