The Shetland Isles are a place of breathtaking landscapes and pristine wildlife. As harsh as the weather can be, so warm and welcoming are the people and their proud half-Scottish, half-Scandinavian culture. Practising psychiatry in this northernmost outpost of the UK involves significant challenges. The authors were the only two psychiatrists based on this remote island group, which is home to 23 000 people.

A New Species

A new scincid lizard, Plestiodon takarai sp. nov., is described from the Senkaku Group, Ryukyu Archipelago, Japan. The Plestiodon lizards in this island group have previously been identified as P. elegans because they all exhibit a patch of enlarged and irregularly arranged scales on the posterior surface of their femurs. However, detailed molecular analyses revealed that the Senkaku population, although closely related to P. elegans and other species in the P. latiscutatus species group, is substantially diverged from all other recognized species. Furthermore, although the Senkaku population largely exhibits the characteristic morphological features of this species group, it can be differentiated from all recognized species by the scutellation and hatchling tail coloration. The biogeographical and conservation implications of these findings are briefly discussed.

Distribution Network Planning

In view of faults which the traditional genetic algorithm (GA) have such as slow convergence speed and easy to fall into the local optimum. This paper put forward a genetic algorithm which is based on the multi-island group strategy, and applied it to the distribution network planning. The paper has established a planning model which takes the yearly comprehensive cost as objective function and discusses the repair methods of islands, solitary chain and closed-loop to meet with the requirements of grid radial. Finally, the proposed method is planning on a 54-node grid to prove the effectiveness of the algorithm and model.

AbstractThe Bedded Series of the Mona Complex at Rhoscolyn comprises two groups of clastic metasediments: the Holy Island Group, consistingof quartzites, impure psammites and pelites, with well-preserved bedding, is overlain conformably by the New Harbour Group, which is for the most parthomogeneously semi-pelitic without surviving bedding. Both groups have undergone the same two major tectono-metamorphic episodes, but with differing response. In the Holy Island Group the first episode (Dx) produced nearly upright and upward-facing folds (Fx) with an axial planar foliation (Sx), which varies from an anastomosing or rough-spaced cleavage in quartzites to a penetrative phyllitic schistosity in pelites. In the New Harbour Group Dx has generally obliterated original bedding surfaces, replacing them with a composite foliation (Sx) of fine compositional banding and a penetrative schistosity, together with a stretching lineation (Lx), the latter being at a high angle to the Fx axial direction. The Dx structures are attributed to a major episode of compressional tectonics.The structures attributed to the second deformation (Dy) includestrata-bound sets of quartz-filled tension fractures (attributed by most previous authors to an earlier episode), abundant NNW-verging asymmetric folds (Fy) of Sx, and a sporadically developed set of shear fractures which constitute a crenulation cleavage (Sy) axial planar to the folds. It is suggested that all these structures were produced by a single agency. One interpretation is that the observed shear fractures and folded tension fractures correspond fairly closely to and provide a natural analogy of those obtained in the classical simple shear experimentsof Riedel. In this case all the Dy structures can be accounted for by the action of a large-scale simple shear couple (Cy), whose vergence and shallow dip were both towards the NNW. Such a mechanism may imply a gravity-dominated regime of net horizontal extension in a NNW-SSE direction, with extension being less constrained to the north than to the south. J. W. Cosgrove has suggested an alternative interpretation, that all the Dy structures can be explained as reverse kink bands; the simple shear interpretation is here preferred because the angle between Sy and the estimated direction of Pmax during Dy was < 45°; the kink band model would require an angle > 45°.The fact that cleavage vergence boundaries for both Sx and Sy occur close to the hinge zone of the Rhoscolyn Antiform is consistent with either Dx or Dy age for the initiation of this fold. However, when fold limb length (or limb rotation) vergence is considered, the presence of an Fx0 vergence boundary but absence of an Fxy vergence boundary (and by implication of an Fy0 boundary) is consistent with a Dx age but difficult to reconcile with a Dy age.

Survey Results

Survei arkeologi sangat penting untuk penemuan dan interpretasi sisa-sisa yang ditinggalkan oleh aktivitas manusia prasejarah. Saat ini penginderaan jarak jauh dan model prediktif telah meningkatkan jangkauan dan keberhasilan survei arkeologi, namun survei pejalan kaki untuk mengembangkan parameter model dan prediksi kebenaran dasar masih penting untuk keberhasilan suatu penemuan. Penelitian ini merupakan hasil survei arkeologi tahun 2017 di Pulau Babar Besar dan Pulau Wetang yang termasuk dalam bagian dari kelompok Kepulauan Babar, Maluku Barat Daya, Indonesia. Tercatat sebanyak 62 situs arkeologi ditemukan di kedua pulau tersebut, tujuh diantaranya merupakan situs lukisan cadas baru yang ditemukan di Pulau Wetang. Hasil survei ini menunjukkan keberhasilan penggunaan peta geologi dan topografi di samping citra satelit dalam mendeteksi daerah prospektif untuk survei. Hasil penelitian ini juga menunjukkan bahwa pemahaman karakteristik geologi daerah yang lebih rinci dan komparatif diperlukan sebelum dilakukan survei jarak jauh yang lebih lanjut di wilayah Maluku Barat Daya, Indonesia.Archaeological surveys are essential to the discovery and interpretation of remains left by past human activities. While remote sensing and predictive models have greatly improved the reach and success of archaeological survey, pedestrian surveys to develop model parameters and ground-truth predictions is still imperative for successful discoveries. Here we present the results of the 2017 archaeological survey of islands Babar Besar and Wetang in the Babar Island Group, Maluku Barat Daya, Indonesia. A total of 62 archaeological sites were recorded between the two islands; seven of which represent new rock art sites on Wetang island. Our survey results indicate the successful use of geological and topographic maps alongside satellite images in detecting prospective regions for survey. Results also indicate however that a more detailed and comparative understanding of the regions geology is required before more advanced forms of remote survey are conducted in the Maluku Barat Daya region.

Abstract This paper is a summary of the more important results of glaciological investigations carried out in Trinity Peninsula, Graham Land during 1958–60, and which will be published at length in Falkland Islands Dependencies Survey Scientific Report No. 42. The budgets for Depot Glacier and the ice piedmont between Hope Bay and Trepassey Bay are given and it is concluded that in a normal year they are in a state of near equilibrium. The state of the glaciers of southern Trinity Peninsula is discussed in a consideration of the importance of rime ice formation on the west coast of the peninsula. Movement and accumulation studies in Trinity Peninsula and the islands of the James Ross Island group demonstrate a decrease in glacierization south-eastwards from the central plateau area. The recent glacial history of the area is also briefly reviewed.
