In a recent statistical study of settlement patterns at Tikal, Guatemala, Arnold and Ford failed to find evidence for the concentric zonation model which specifies that high-ranking persons generally lived closer to the site center than persons of lesser rank. However, their conclusions are invalidated by their exclusion from consideration of the houses occupied by the wealthy and powerful members of Tikal society. Attention is called to other deranging factors which need to be considered before a valid test of the concentric zonation model can be carried out Tikal, or at any other large and complex site.

La sabermetría es reconocida actualmente como una tendencia novedosa en el estudio del juego de béisbol. Con mucho auge y utilización en el análisis empírico, esta se basa en el estudio estadístico riguroso de la evidencia objetiva obtenida durante el juego. Teniendo en cuenta tanto sus aportes teóricos como prácticos, la sabermetría se fundamenta en una constante búsqueda por comprender cómo jugar mejor y más eficientemente al béisbol, lo cual se expresa y soporta mediante un tipo de análisis de actuación único entre todos los deportes colectivos. El presente trabajo aborda los aspectos esenciales de la sabermetría, fundamentando la necesidad de su surgimiento y utilización, como una forma de perfeccionar la manera en que tradicionalmente se ha llevado a cabo el análisis estadístico en el béisbol. Además, se brinda un resumen de los estadísticos sabermétricos más utilizados, tanto de bateo y picheo como otros de valor individual para el equipo, con el propósito de hacer más clara su comprensión, estudio y posterior utilización entre los seguidores de este deporte.Abstract. Sabermetrics is recognized as a new trend in the study of baseball game. This is based on the rigorous statistical study of the objective evidence obtained and has been used extensively in its empirical analysis. Considering both theoretical and practical contributions, sabermetrics involves the constant quest of understanding how to play baseball better and more efficiently, which is expressed and supported by an exceptional type of analysis performance unique among all team sports. This paper describes the essential aspects of sabermetrics, pointing in the necessity of its emergence and use, as a way to improve the traditional statistical analysis of baseball. Moreover, a summary of the sabermetrics statistics most widely used is given. Both batting and pitching, as well as others of individual value for the team are stated throughout this work in order to make sabermetrics understanding, study and further use clearer among followers of this sport.

The Web

In common Internet environments, most of the websites or services constrain the user account creation. Since the Internet is accessible by all and offers more and more services, a user has several accounts on the web. The difficulty in controlling their accounts does not leave indifferent to the users of the web. Hence the use of easy or insecure passwords. This is why we are victims of attacks and forgetting our passwords. Large companies such as Facebook, Google, etc., offer authorization and authentication mechanisms using the Oauth and OpenID protocol, which requires the opening of an account. To be independent of a social network or a site, it would be important to develop a model to make a statistical analysis between the attributes of the profiles of the same user and to create an account. Using the same password for all its different accounts could be an approach but avoiding the proliferation of data by proposing a model of identity analysis would be even more interesting. That is why this article proposes a centralized account management model by making a comparative and statistical study of the identity attributes and proposing a single account to the user to manage all its different accounts. So, we have a horizontal analysis between the attributes of the identity categories and a vertical analysis between these categories. This study allowed us to find a threshold to conclude that an account belongs to a user.

Statistical analysis of rainfall pattern and its variability for 20 years (1990-2010) data is performed for two mountainous urban centres of Uttarakhand i.e. Almora (29.60 N, 79.670 E and altitude 1,204m asl) and Nainital (29.40 N, 79.470 E and altitude 2,020m asl). Non Parametric method of Principal Component Analysis (PCA) gives the correlation between different extreme rainfall indices. It is concluded that PCA suggest 90% of the variance in composite matrix of extreme rainfall indices.

The flight performance and maneuverability of Odonata depends on wing shape and aero-structural characteristics, including airfoil shape, wingspan, and chord. Despite the superficial similarity between Odonata planforms, the frequency with which they are portrayed artistically, and the research interest in their aerodynamics, those features that are stable and those that are labile between species have not been identified. Studies have been done on 2D aerodynamics over corrugated wings; however, there is limited comparative quantified data on the planforms of Odonata wings. This study was undertaken to explore the scale relationships between the geometrical parameters of photogrammetrically reconstructed wings of 75 Odonata species, 66 from Epiprocta, and 9 from Zygoptera. The wing semi-spans captured in the database range from 24 to 85 mm. By carrying out an extensive statistical analysis of data, we show that the geometrical parameters for the suborder Epiprocta (dragonflies) can be classified into scale-dependent and independent parameters using regression analysis. A number of close correlations were found between the wingspan and the size of other structures. We found that amongst the variables considered, the largest independent variations against the forewing span were found in the chord of the hindwing, and that hindwing properties were not reliably predicted by the Odonata family. We suggest that this indicates continuous evolutionary pressure on this structure.

Little attention has until now been directed to the rich information on title-holders contained in the two chronicles of the imām Aḥmad b. Furṭū written in 1576 and 1578 respectively. This neglect is partly due to the very confusing style of the imām's writing. In particular, he refers to the three highest ranking Bornoan officials by translating their Bornoan titles into Arabic: the Digma is called ‘al-wazīr al-kabīr’, the great Jarma ‘al-rā'id al-kabīr’, and the Cikama ‘al-ḥājib’. Once the meaning of these Arabic titles is decoded it appears that the political organisation of sixteenth century Borno owes very little to the Islamic model. Furthermore it becomes clear that the commander of the Bornoan corps of musketeers was the great Jarma, an official of Ngizim origin, and not a Turkish military instructor as one may have suspected.However, since Ibn Furṭū is mainly concerned with military activities, only a few functions of the three high-ranking court officials emerge from his account; others have to be inferred from the information provided by nineteenth-century European travellers and from more recent anthropological accounts. In Borno the political organisation of the Sayfuwa state fell to pieces in the first half of the nineteenth century, when al-Amīn al-Kānemī and his successors built up a new system of administration. This progressively supplanted the old system, which was based on a great number of court titles and attendant offices. Important elements of the political organisation of the Sayfuwa survive until the present day in some former vassal states of Borno which became independent in the course of the nineteenth century or earlier.

Residential Units

The widely applied concentric zonation model for Classic period Maya centers, which specifies that high-ranking persons lived closer to the central civic-ceremonial precinct than low-ranking persons, is tested for the site of Tikal. Our method is to identify residential units from the Carr and Hazard (1961) Tikal maps and to compute labor investment costs of construction of residential units from variables derived exclusively from the cartographic data. Our finding is that the Tikal data do not substantiate the concentric zonation model.

AbstractA blind, randomized laboratory trial to study homoeopathic potencies of Arsenicum album on wheat germination is proposed as a simple model which allows a rigorous statistical analysis. The parametric tests show that the differences between the treatment groups cannot be explained as a mere effect of intrinsic seed variability.

Abstract A new three-dimensional reflectivity echo in the rear flank of supercells known as the descending reflectivity core (DRC) has been documented in the literature by Rasmussen et al. The DRC is an enhanced region of reflectivity presumed to occur in the rear-flank downdraft (RFD) of a supercell. In the four cases they studied, this feature descended with time from the rear-echo overhang at 3–6 km in height into the supercell appendage. In addition, the DRC often occurred prior to tornadogenesis. The purpose of this paper is to serve as a more thorough analysis of DRCs using a larger sample of storms. The frequency of DRCs is explored within isolated supercells with persistent rear-flank appendages, and in particular at times preceding reported tornado onset in those supercells. Of the 64 supercells included within this study, 59% produced DRCs, with 30% of these DRCs occurring within 10 min prior to 5 min after tornadogenesis. This study included 89 reported tornadoes and 71 DRCs. Statistical analysis of the dataset reveals that while DRCs are sometimes associated with tornadoes, they presently have limited usefulness for tornado nowcasting. Improvements to Weather Surveillance Radar-1988 Doppler (WSR-88D) resolution and further classification of DRCs may help discriminate between tornadic and nontornadic appendages in the future, however.

Statistical study of the correlation between 49 variables concerning characteristics of headache and of headache patients was carried out on 1,198 sequential patients complaining of severe or disabling headaches and attending a headache clinic. Factor analysis was the statistical method employed, 17 factors accounting for 64% of total variation emerged. The most prominent factor contained descriptors of neurological dysfunction associated with headache. Another factor contained variables of nausea and vomiting, only associated with inability to work. Other factors, contained separately, the following variables: (a) Time of headache, (b) time of week of headache, (c) unilateral nature of headache, (d) visual phenomena associated with headache. Relation of these findings to headache taxonomy is discussed.
