Sexual dimorphism has been poorly evaluated or investigated in Pleistocene Eurasian Stephanorhinus species, leaving a gap in our knowledge about their morphometric variability. Among the representatives of this genus, S. etruscus is the most abundant species, with several remains collected from Western European localities, allowing us to investigate the presence of sexual dimorphism in the limb bones of this taxon. We considered measurements taken on 45 postcranial variables and three different statistical metrics to identify patterns of bimodality in the dataset. This work represents the first application of sex-combined statistical analysis to a dataset composed of individuals from various European localities. The morphometrical analyses revealed that a relatively weak sexual dimorphism is present in all the considered bones. Larger forelimbs and hindlimbs are interpreted as belonging to adult males of S. etruscus, similarly to what was observed in the modern Sumatran rhino, where males are a little bit larger than females. The recognition of a weak sexual dimorphism in the postcranial bones of S. etruscus increases our understanding of the paleoecology of this extinct taxon. However, only a better study of the morphological and morphometrical variability of the crania of fossil rhinoceroses could deeply contribute to the investigation of the social habits and behavior of these taxa.

Recently there has been an increasing adoption of electronic health records (EHRs) in different countries. Thanks to these systems, multiple health bodies can now store, manage and process their data effectively. However, the existence of such powerful and meticulous entities raise new challenges and issues for health practitioners. In fact, while the main objective of EHRs is to gain actionable big data insights from the health workflow, very few physicians exploit widely analytic tools, this is mainly due to the fact of having to deal with multiple systems and steps, which completely discourage them from engaging more and more. In this paper, we shed light and explore precisely the proper adaptation of analytical tools to EHRs in order to upgrade their use by health practitioners. For that, we present a case study of the implementation process of an EHR based OpenEHR and investigate health analytics adoption in each step of the methodology. [ABSTRACT FROM AUTHOR]

Over the last few years, big data has emerged as an important topic of discussion in most firms owing to its ability of creation, storage and processing of content at a reasonable price. Big data consists of advanced tools and techniques to process large volumes of data in organisations. Investment in big data analytics has almost become a necessity in large-sized firms, particularly multinational companies, for its unique benefits, particularly in prediction and identification of various trends. Some of the most popular big data analytics software used today are MapReduce, Hive, Tableau and Hive, while the framework Hadoop enables easy processing of such extremely large data sets. The current research attempts to create a comparative assessment of five such applications namely IBM SPSS, IBM Watson Analytics, R, Minitab and SAS. The case taken into effect for the test was that of the factors affecting housing affordability in the US. Based on the statistics obtained from the American Housing Survey (AHS) database, the researcher has identified different factors impacting the affordability in the states. The technique of reducing variables though Principal Component Analysis (PCA) and a model based on partial least square regression/polynomial regression was fitted to check the impact on the affordability. The primary findings suggest that majorly age of the head of the household, income earned were the two most important factors affecting the pricing in the region. Also, a comparison is drawn at the end of study with interpretation of the most and least effective applications. [ABSTRACT FROM AUTHOR]

design research ,analytic methods ,analytic tools ,data visualization - Abstract
Emerging online research platforms are bringing new efficiencies to the design research process. But the resulting data is large in scope and dense in nature. And the analytic tools and approaches design teams have come to rely on were not designed to manage this scale of inquiry. As design problems expand in complexity and require more inputs, generating big qualitative data sets is likely to become the new norm. This paper proposes two ways to manage this new condition: (1) adding visual coding techniques to textual coding to counteract "data sameness" and "data sprawl," and (2) developing new tools to support fast meta explorations of data sets.

Benuzillo, Jose, Savitz, Lucy A., and Evans, Scott
- Abstract
Artificial intelligence (AI) is becoming ubiquitous in health care, largely through machine learning and predictive analytics applications. Recent applications of AI to common health care scenarios, such as screening and diagnosing, have fueled optimism about the use of advanced analytics to improve care. Careful and objective considerations need to be made before implementing an advanced analytics solution. Critical evaluation before, during, and after its implementation will ensure safe care, good outcomes, and the elimination of waste. In this commentary we offer basic practical considerations for developing, implementing, and evaluating such solutions based on many years of experience. [ABSTRACT FROM AUTHOR]

ASSISTIVE technology ,KNOWLEDGE transfer - Abstract
The United States government funds research and development programs to advance the state of technological innovations across many fields. One targeted field is assistive technology devices and services for persons with disabilities. Although these sponsored programs intend to benefit society, they channel most of their funding to universitybased scholars. This approach leaves a gap between the specific project outputs (academic papers, patent claims), and their transformation into products, services and related outcomes capable of delivering beneficial socio-economic impacts. One participant/ observer recounts one government agency's efforts to bridge this gap over the past twenty-five years, by initiating projects addressing the transformational processes of technology transfer and knowledge translation.

Big data analytics can add value and provide a new perspective by improving predictive analysis and modeling practices. This research is centered on supply-chain management and how big data analytics can help Romanian supply-chain companies assess their experience, strategies, and professional capabilities in successfully implementing big data analytics, as well as assessing the tools needed to achieve these goals, including the results of implementation and performance achievement based on them. The research method used in the quantitative study was a sampling survey, using a questionnaire as a data collection tool. It included closed questions, measured with nominal and ordinal scales. A total of 205 managers provided complete and useful answers for this research. The collected data were analyzed with the Statistical Package for the Social Sciences (SPSS) package using frequency tables, contingency tables, and main component analysis. The major contributions of this research highlight the fact that companies are concerned with identifying new statistical methods, tools, and approaches, such as cloud computing and security technologies, that need to be rigorously explored.

Formal grammatical description has not generally been applied in the human factors area, which traditionally draws on behavioral science for its methodology. This paper illustrates, by means of a detailed example, how formal grammatical description can be used as a predictive tool to compare alternative designs for ease of use and to identify design choices which could cause users to make mistakes. The paper describes the human interface for two versions of an interactive graphics system intended for use by nonprogrammers. It presents the "action languages" for the two versions, then shows how these user languages can be described in terms of a production rule notation. Particular emphasis is given, in the notation, to actions the user has to learn and remember (i.e., to "cognitive" factors). The paper then presents predictions about human performance based on the formal description, and exploratory results of testing some of the predictions. Since the predictions arc based on general properties of the formal description, the technique should also be applicable to other "action languages." [ABSTRACT FROM AUTHOR]

- Abstract
Dashboards are information management tools , for monitoring and analysing of different organization’s behaviour. The purpose of management Dashboards is to observe, identify and solve problems and to justify patterns with monitoring the key performance indicators. T he Dashboards are not just reporting tools , they are interactive communication tools with meaning and purpose. They can analyse big amount of data and return as a result complete storyline of information letting the audience to understand how an organizati on works. Thus, this Master Thesis aims to identify and analytically examine the key features, purposes, uses, and benefits of performance dashboards and to develop a Higher Education Management Dashboard in R for the needs of MASTEAM Master of the Polyte chnic University of Catalonia ( UPC ) . The Thesis is highlighting the methodology and the designing rules for creating dashboards and taking the full pote ntial and benefits of them. Based on them, in the Thesis is implemented a real education management Das hboard in R programing language . The fundamental rules are used for the implementation of the MASTEAM Master Dashboard . The Dashboard will include the most important features and information about the MASTEAM, which are pointed from the coordinator of the MASTEAM through an interview . T he main goal is to give the coordinator the ability to observe and analyse the behaviour of significant areas in the Master. For instance , some of the areas are the enrolment status, student’s information, grades, courses, graduated rates, etc. Finally, the results of the programing part will demonstrate the last version of the MASTEAM Dashboard web page that can be used from the coordinator . He can monitor the behaviour of the Maste r and take necessary decisions . A ccordin g to the visualised data, the maintenance of the good condition of the existing Master is also possible .

Globalisation, volatile markets, legal changes and technical progress have an immense impact on business environments in most industries. More and more IT is deployed to manage the complexity. As a result, companies and organisations have to handle growing volumes of data which have become a valuable asset. The ability to benefit from this asset is increasingly essential for business success. Therefore, fast storage, reliable data access, intelligent information retrieval, and new decision-making mechanisms are required. Business Intelligence (BI) and Performance Management (PM) offer solutions to these challenges.

Exploitant les résultats d'une enquête ethnographique d'une société de multigestion, cette communication souhaite contribuer à une sociologie du calcul financier. Elle entend montrer que la rationalité financière gagne à être pensée à partir des modes de raisonnement effectivement menés par les acteurs qui pratiquent des activités financières, et non pas comme une entité logique transcendantale. Elle s'attache aux agents de rationalisation des processus de (multi-) gestion d'actifs et porte une attention particulière aux outils avec lesquels travaillent les analystes-multigérants pour choisir les fonds qu'ils intégreront à leurs portefeuilles. Ces éléments structurent la perception que les acteurs ont du monde de la gestion et construisent un ordre rationnel dans lequel se déploie l'activité. Mais ils n'empêchent pas les acteurs d'élaborer à leur tour des instruments symboliques avec lesquels donner sens à leur action. Au contraire, les artefacts matériels ou immatériels (supports d'écriture et formules de calcul par exemple) sont la trace d'une action humaine structurante autant qu'ils la structurent à leur tour. Résultant d'efforts destinés à dégager un profit monétaire dans un univers concurrentiel, les régimes de rationalité qui les accompagnent sont solidaires de pratiques de gestion qui sont elles-mêmes en affinité avec les positions qu'occupent les acteurs dans ce sous-espace de l'industrie financière.

- Abstract
In August 2009, the North Atlantic Treaty Organization s International Security Assistance Force mission shifted from an enemy-centric, anti-insurgency campaign to a broader, population-centric counterinsurgency. This strategy change immediately presented challenges to field of intelligence and its existing analytic methods as it struggled to cope with the complexity of population analysis. However, a wave of innovation under the name of complexity theory is spreading through mathematics, computer science, biology, economics, and sociology that do cope with the challenges of analyzing entities as complex as populations. The Emergent States Assessment (ESA) is an analytic tool that attempts to exploit this wave to support decision makers in Counterinsurgency and Stability Operations. To demonstrate the potential power of viewing populations through the lens of complexity this article examines the phenomenon of corruption in Afghanistan through the ESA framework., Published in Small Wars Journal, August 26, 2011.

- Abstract
Purpose. This project evaluated WinMine, an analytic tool developed by Chickering, Heckerman, Meek, Platt, and Thiesson (2000) to determine its usefulness for identifying higher-order relationships in research data from dynamic and high-consequence aviation events. Traditionally, researchers have relied on several types of analyses to better understand the relationships between factors related to an outcome. However, researchers need an analytic approach that can clearly illustrate the interactions among causal factors as probabilities associated with the chain of events. Method. A convenience sample of aviation accident data previously classified using the Human Factors Analysis and Classification System (HFACS; Shappell & Wiegmann, 2000; 2001) was used to evaluate WinMine in contrast to traditional methods, such as bar graphs, contingency tables, and odds ratios. Results. WinMine showed an advantage when compared with other methods because it graphs quantifiable interrelationships between factors and illuminates the underlying hierarchical structure of variables. Discussion. Each technique examined contributed toward understanding the causal factors; however, WinMine provided a better picture of the factor interrelationships than the other methods., Work was accomplished under approved task AHRR522.
