<p>Tourism climatology is a popular field of study that deals with the relationship between tourism and climate through approaches such as applied climatology and human biometeorology. One of the subjects studied most in this field is the evaluation of bioclimatic comfort conditions. In recent years, inferences of this sort have been able to be made easily by use of certain indices. This study aims at evaluating and analyzing the bioclimatic comfort conditions of Artvin province by use of GIS. Within the scope of the research aim, monthly values belonging to SET*, PET, PMV, TCI, THI and SSI indices were calculated by use of meteorological data. SET*, PET, and PMV indices were determined via RayMan 1.2 while TCI, THI, and SSI indices were ascertained through Microsoft Excel 2013 supported analyses of various formulas. The obtained values were analyzed through GIS techniques. Also, statistical methods were utilized to make the research findings more meaningful. All in all, the province was seen to have comfortable conditions. This is because; the comfortable (1) class (68.9%) covers a wider area than uncomfortable (0) class (31.1%) in the province. Bioclimatic comfort classes are shaped by geographical position, elevation, and topography in Artvin province. Valleys with an elevation of less than 2000 m and coastal area are comfortable while mountainous areas (Rize, Kaçkar, Karçal, and Yalnızçam mounts) with a higher elevation are uncomfortable. The results of one-way analysis of variance (one-sample t-test) show that bioclimatic conditions have not been taken into consideration much during the planning of tourism accommodation facilities set up in Artvin province. This study evidences that GIS techniques are efficient in research on tourism climatology or bioclimatology and thus they may be used widely.</p><p> </p><p><strong>Özet</strong></p><p>Turizm klimatolojisi, uygulamalı klimatoloji ile insan biyometeorolojisi gibi yaklaşımlarla turizm ve iklim arasındaki ilişkiyi inceleyen popüler bir çalışma sahasıdır. Bu sahada çalışılan öncelikli konulardan birisi de biyoklimatik konfor şartlarının değerlendirilmesidir. Son yıllarda bu tür çıkarımlar CBS (Coğrafi Bilgi Sistemleri) destekli olarak bazı indisler yardımıyla kolayca yapılabilmektedir. Bu çalışmada CBS kullanılarak Artvin ilinin biyoklimatik konfor şartlarının değerlendirilmesi ve analizinin yapılması amaçlanmıştır. Çalışma amacı kapsamında meteorolojik veriler kullanılarak SET*, PET, PMV, TCI, THI ve SSI indislerine ait aylık değerler hesaplanmıştır. SET*, PET ve PMV RayMan 1.2 yazılımı, TCI, THI ve SSI ise çeşitli formüllerin Microsoft Excel 2013 destekli çözümlenmesiyle saptanmıştır. Ulaşılan değerler CBS teknikleriyle analiz edilmiştir. Ayrıca çalışma bulgularını daha anlamlı kılmak amacıyla istatistiksel analiz yöntemlerinden de faydalanılmıştır. Sonuçta ilin konforlu şartlar taşıdığı saptanmıştır. Zira ilde konforlu (1) sınıf (% 68,9) konforsuz (0) sınıfa (% 31,1) oranla daha fazla alan kaplamaktadır. Diğer yandan ildeki biyoklimatik konfor sınıflarının coğrafi konum, yükseklik ve topoğrafik şartlara göre şekillendiği tespit edilmiştir. Bu bağlamda 2000 m yükselti basamağının altındaki vadiler ile kıyı sahası konforlu, üzerindeki dağlık kesimler (Rize, Kaçkar, Karçal ve Yalnızçam dağları) ise konforsuz özelliklere sahiptir. Ayrıca tek yönlü varyans analizi (tek örneklem t-testi) sonuçlarına göre Artvin ilinde yapılmış turizm konaklama tesislerinin planlamalarında biyoklimatik koşulların çok fazla dikkate alınmadığı da belirlenmiştir. Bu çalışma sayesinde turizm klimatolojisine veya biyoklimatolojiye yönelik araştırmalarda CBS tekniklerinin verimli olduğu ve yaygın bir şekilde kullanılabileceğini bir kez daha somut olarak anlaşılmıştır.</p>

Abstract. The Greater Caucasus mountain belt is characterized by deep valleys, steep slopes and frequent seismic activity, the combination of which results in major landslide hazard. Along the eastern side of the Enguri water reservoir lies the active Khoko landside, whose head scarp zone affects the important Jvari-Khaishi-Mestia road, one of the few connections with the interior of the Greater Caucasus. Here, we present a database of measurement time series taken over a period of 4 years (2016–2019) that enable to compare slope deformation with meteorological factors and man-induced perturbations owing to variations in the water level of the reservoir. The monitoring system we used is composed of two digital extensometers, placed within two artificial trenches excavated across the landslide head scarp. The stations are equipped also with internal and near ground surface thermometers. The data set is integrated by daily measurements of rainfall and lake level. The monitoring system was set up in the framework of a NATO-funded project, aimed at assessing different types of geohazards affecting the Enguri artificial reservoir and the related hydroelectrical plant. Our results indicate that the Khoko landslide displacements appear to be controlled by variations in hydraulic load, in turn induced by lake level oscillations, with a delay of months between lake infilling and extension rate increase. Rainfall and temperature variations do not seem to affect slope deformations.

What are the long-term effects of colonial institutions on insurgency? My article shows the historical origins of insurgency by addressing the puzzle of why the persistent Maoist insurgency, considered to be India’s biggest internal security threat, affects some districts along the central eastern corridor of India but not others. Combining archival and interview data from fieldwork in Maoist zones with an original district-level quantitative data set, I demonstrate that different types of British colonial indirect rule set up the structural conditions of ethnic inequality and state weakness that facilitate emergence of Maoist control. I address the issue of selection bias, by developing a new instrument for the British choice of indirect rule through princely states, based on the exogenous effect of wars in Europe on British decisions in India. This article reconceptualizes colonial indirect rule and also presents new data on rebel control and precolonial rebellions.

Although multiple organizational-level databases are frequently combined into one data set, there is no overview of the matching methods (MMs) that are utilized because the vast majority of studies does not report how this was done. Furthermore, it is unclear what the differences are between the utilized methods, and it is unclear whether research findings might be influenced by the utilized method. This article describes four commonly used methods for matching databases and potential issues. An empirical comparison of those methods used to combine regularly used organizational-level databases reveals large differences in the number of observations obtained. Furthermore, empirical analyses of these different methods reveal that several of them produce both systematic and random errors. These errors can result in erroneous estimations of regression coefficients in terms of direction and/or size as well as an issue where truly significant relationships might be found to be insignificant. This shows that research findings can be influenced by the MM used, which would argue in favor of the establishment of a preferred method as well as more transparency on the utilized method in future studies. This article provides insight into the matching process and methods, suggests a preferred method, and should aid researchers, reviewers, and editors with both combining multiple databases and describing and assessing them.

Since the start of the National Health Service, data have been collected on admissions to psychiatric in-patient units, first as the Mental Health Enquiry, then as part of Hospital Episode Statistics. Some details have changed but many have stayed remarkably consistent. Published literature on the wide range of research and policy work undertaken using this data source is reviewed. Early work was central to the government's deinstitutionalisation policy in the early 1960s. Subsequent studies cover a wide range of epidemiological and health services research issues. A new statistical base, the Mental Health Minimum Data Set, covering individuals receiving all types of health care is currently being set up. This will supplement (but not replace) admission statistics.

Abstract. In 1997 the International Maritime Organisation (IMO) adopted MARPOL Annex VI to prevent air pollution by shipping emissions. It regulates, among other issues, the sulfur content in shipping fuels, which is transformed into the air pollutant sulfur dioxide (SO2) during combustion. Within designated Sulfur Emission Control Areas (SECA), the sulfur content was limited to 1 %, and on 1 January 2015, this limit was further reduced to 0.1 %. Here we present the set-up and measurement results of a permanent ship emission monitoring site near Hamburg harbour in the North Sea SECA. Trace gas measurements are conducted with in situ instruments and a data set from September 2014 to January 2015 is presented. By combining measurements of carbon dioxide (CO2) and SO2 with ship position data, it is possible to deduce the sulfur fuel content of individual ships passing the measurement station, thus facilitating the monitoring of compliance of ships with the IMO regulations. While compliance is almost 100 % for the 2014 data, it decreases only very little in 2015 to 95.4 % despite the much stricter limit. We analysed more than 1400 ship plumes in total and for months with favourable conditions, up to 40 % of all ships entering and leaving Hamburg harbour could be checked for their sulfur fuel content.

The Institute of Jet Propulsion at the University of the German Federal Armed Forces Munich has developed and patented a novel concept of air injection systems for active aerodynamic stabilization of turbo compressors. This so-called Ejector Injection System (EIS) utilizes the ejector effect to enhance efficiency and impact of the aerodynamic stabilization of the Larzac 04 two-spool turbofan engine’s LPC. The EIS design manufactured recently has been subject to CFD and experimental pre-investigations in which the expected ejector effect performance has been proven and the CFD set-up has been validated. Subsequently, optimization of the EIS ejector geometry comes into focus in order to enhance its performance. In this context, CFD parameter studies on the influence of in total 16 geometric and several aerodynamic parameters on the ejector effect are required. However, the existing and validated CFD set-up of the EIS comprises not only the mainly axisymmetric ejector geometry but also the highly complex 3D supply components upstream of the ejector geometry. This is hindering large scale CFD parameter studies due to the numerical effort required for these full 3D CFD simulations. Therefore, an approach to exploit the overall axissymmetry of the ejector geometry is presented within this paper which reduces the numerical effort required for CFD simulations of the EIS by more than 90%. This approach is verified by means of both experimental results as well as CFD predictions of the full 3D set-up. The comprehensive verification data set contains wall pressure distributions and the mass flow rates involved at various Aerodynamic Operating Points (AOP). Furthermore, limitations of the approach are revealed concerning its suitability e.g. to judge the response of the attached compressor of future EIS designs concerning aerodynamic stability or cyclic loading.

We propose a complete methodology for the fine registration and referencing of kilo-station networks of terrestrial laser scanner data currently used for many valuable purposes such as 3D as-built reconstruction of Building Information Models (BIM) or industrial asbuilt mock-ups. This comprehensive target-based process aims to achieve the global tolerance below a few centimetres across a 3D network including more than 1,000 laser stations spread over 10 floors. This procedure is particularly valuable for 3D networks of indoor congested environments. In situ, the use of terrestrial laser scanners, the layout of the targets and the set-up of a topographic control network should comply with the expert methods specific to surveyors. Using parametric and reduced Gauss-Helmert models, the network is expressed as a set of functional constraints with a related stochastic model. During the post-processing phase inspired by geodesy methods, a robust cost function is minimised. At the scale of such a data set, the complexity of the 3D network is beyond comprehension. The surveyor, even an expert, must be supported, in his analysis, by digital and visual indicators. In addition to the standard indicators used for the adjustment methods, including Baarda’s reliability, we introduce spectral analysis tools of graph theory for identifying different types of errors or a lack of robustness of the system as well as <i>in fine</i> documenting the quality of the registration.

There has recently been much discussion of large-scale interactions of fault zones and the influence of large-scale processes in the preparation and triggering of earthquakes. As a consequence, an official recommendation was issued to set up observational networks at regional scale. In this context, the existing network of standard geomagnetic observatories might play a more important role in future tectonomagnetic studies. The data from standard geomagnetic observatories are basically not appropriate for the detection of small-magnitude and, in most cases, spatially very localized geomagnetic field changes. However, their advantage is a continuity in a long-time period which enables the study of regional tectonomagnetic features and long-term precursory changes. As the first step of a more extensive study aimed at examining the features of observatory data for this purpose, a three-year data set from five European observatories has been analyzed. Some common statistical procedures have been applied along with a simple difference technique and multivariate linear regression to define local geomagnetic field changes. The distribution of M ³ 4.5 earthquakes in Europe, in a corresponding period, was also taken into account. No pronounced field variation, related in time to the M 5.7 Timisoara (Romania) earthquake on July 12, 1991, was found at Grocka observatory at about 80 km from the earthquake epicenter. However, an offset in level of the differences in declination which include Grocka observatory, not seen in the case of differences between other observatories, could be associated with a possible regional effect of the M 4.8 earthquake which occurred in September 1991 at about 70 km SE from Grocka.

This article reveals the role of Burdah as an Arabic literary book that has become a regular practice of the Moslem community in Manado. The researcher tries to find out the social and cultural aspects through the Arabic text pertaining to concrete condition where the content of the book is practiced and this serves as the key to comprehend the users’ view and thinking pattern. The problems paralleled to the research objective is identifying and analyzing the social, spiritual and metaphysical reflection. The research findings indicate socially, there is a unitary perception in which the user community is called to set up an organization to learn about the book. The projected spiritual transformation of the book as a prophecy work toward a future hope makes it a routine regular practice at wedding ceremony, housewarming, and children under five thanksgiving. Metaphysical transformation is held as a miracle so that this regular practice can cure various diseases. This belief rooted in the user community perception has become a daily routine custom even though the Arabic language read is not understood. Key words: Burdah, spiritual, cultural and metaphysical transformation.
