title: A Convenient and Efficient Synthesis of 2-(Het)arylthieno[3,2-b]pyridin-7(4H)-ones and 2,3-Di(het)arylthieno[3,2-b]pyridin-7(4H)-ones

description: A simple and efficient synthesis of 2-aryl-3-hydroxythieno[3,2-b]pyridin-7(4H)-ones, 7-methoxy-2,3-diarylthieno[3,2-b]pyridines, and 2,3-diarylthieno[3,2-b]pyridin-7(4H)-ones is presented. The synthesis involves thioalkylation of methyl 4-methoxypicolinate at the 3-position, followed by cyclization in situ to give 2-aryl-7-methoxythieno[3,2-b]pyridin-3-ols. Demethylation of these compounds gives the corresponding 2-arylthieno[3,2-b]pyridin-7(4H)-ones. Further functionalization of 7-methoxy-2-aryl­thieno[3,2-b]pyridin-3-ols was achieved by converting the hydroxy group into the corresponding triflate, which underwent palladium-catalyzed cross-coupling to give 7-methoxy-2,3-di(het)arylthieno[3,2-b]pyridines. Subsequent demethylation of the 7-methoxy group gave the corresponding pyridinones.

title: Novel One-Pot Multicomponent Strategy for the Synthesis of Pyrrolo[1,2-a]benzimidazole and Pyrrolo[1,2-a]quinoxaline Derivatives

description: A simple one-pot multicomponent procedure has been developed for the synthesis of pyrrolo[1,2-a]benzimidazole and pyrrolo[1,2-a]quinoxaline derivatives by heating a 1:2:1 molar mixture of a benzimidazole unsubstituted on the imidazole ring, a 2-bromoacetophenone derivative, and a nonsymmetrical activated alkyne in refluxing 2-ethyloxirane. The reaction can be performed under conventional reflux conditions or with microwave irradiation.

title: Nickel-Catalyzed Cross-Electrophile Coupling of 2-Chloropyridines with 
Alkyl Bromides

description: The synthesis of 2-alkylated pyridines by the nickel-catalyzed cross-coupling of two electrophiles, a 2-chloropyridine and an alkyl bromide, is described. Compared with our previously published conditions for aryl halides, this method uses a different, more rigid, bathophenanthroline ligand and is conducted at high concentration in N,N-dimethylformamide as solvent. The method displays promising functional group compatibility and the conditions are ­orthogonal to those for the Stille coupling.

title: Thio-Michael–Aldol–Cyclization Cascade of N-Enoyl Thiazolidinethiones with Aliphatic Aldehydes and Cyclic Ketones

description: A thio-Michael–aldol–cyclization cascade reaction of N-enoyl thiazolidinethiones with aliphatic aldehydes and cyclic ­ketones was promoted by Ti(IV) chloride to deliver highly complex tricyclic adducts possessing a carbon atom tetrasubstituted with ­heteroatoms and up to four stereogenic centers in good to very good yields.

title: Regioselectivity of Intramolecular Rhodium-Catalyzed C–H Insertion Reactions of α-Aryl-α-diazocarboxylates: Influence of the Aryl Substituent

description: It was found that α-aryl-α-diazocarboxylates react with variable regioselectivity in intramolecular rhodium-catalyzed C–H insertion reactions. 3-(Trialkoxysilyl)propyl esters underwent a clean cis-γ-lactone formation (62–69%) if the aryl rest was a phenyl group while the analogous α-(2-bromophenyl)-α-diazocarboxylates produced the respective β-lactones. In general β-lactone formation was shown to be the only detectable C–H insertion pathway for the latter substrate class irrespective of the ester substituent. The β-lactone products (eight examples) were obtained in yields of 41–68% with a diastereomeric ratio (dr) of 75:25 to 96:4 in favor of the trans diastereoisomer. The 2-bromo substituent could be displaced by an aryl group in a subsequent Suzuki cross-coupling reaction.

title: Nickel-Catalyzed sp3 C–H Bond Activation from Decarboxylative Cross­Coupling of α,β-Unsaturated Carboxylic Acids with Amides

description: Nickel-catalyzed functionalization of C(sp3)–H bonds adjacent to a nitrogen atom in amides through decarboxylative cross-coupling of α,β-unsaturated carboxylic acids is reported. A possible reaction mechanism is proposed that involves radical intermediate species.

title: En Route to Novel Furanoside Mimics through Stereoselective Zinc-Mediated Propargylation of N-Benzyl Glycofuranosylamines Using Ultrasound Activation

description: Preliminary results on a novel zinc-mediated, ultrasound-promoted chain extension of glycofuranosylamines with a propargyl group are reported. The procedure was applied to d-arabino and d-xylo substrates to give, via Cram-chelate transition states, 1-C-1-(3-trimethylsilyl-2-propynyl)-1-benzylamino pentionols in moderate to good yields and acceptable stereoselectivities (syn/anti ≥4:1). To apply the reaction to the synthesis of galactofuranoside mimics, the d-xylo intermediate was cyclized to afford a 1-C-1-(2-propynyl)-1,4-dideoxy-1,4-imino-l-arabinitol derivative in excellent yield. This building block was used in three examples of CuAAC click reactions with azide compounds to provide the corresponding galactofuranoside mimics.

title: Conditions and Edges for the Photochemical Generation of Short-Lived Aryl Cations: A Computational Approach

description: A DFT investigation on the conditions required for the photochemical generation of triplet aryl cations from differently para-substituted aryl halides has been carried out. The results showed a correlation between the energy change associated with the Ar–X bond heterolytic cleavage and the substituent Hammett–Brown constant (σp
            +). The method provides a means to predict the viability of the ArSN1 photosubstitution reaction.

title: Highly Regioselective Arylation of 1,2,3-Triazole N-Oxides with Sodium Arenesulfinates via Palladium-Catalyzed Desulfitative Cross-Coupling Reaction

description: A convenient and highly regioselective palladium-catalyzed direct C5-arylation of 1,2,3-triazole N-oxides was developed in the presence of silver carbonate and tripotassium phosphate. This protocol allowed use of sodium arylsulfinates, diphenylphosphine oxide, and triphenylphosphine as arylating reagents to produce 2-aryl-5-aryl-1,2,3-triazole N-oxides in good to excellent yields, providing a complement to the existing methods for the direct arylation of 1,2,3-triazole N-oxides.

title: Big Data and Knowledge-intensive entrepreneurship: trends and opportunities in the tourism sector.

description: The paper focuses on the growing relevance of Big Data as valuable source of knowledge impacting on the creation and execution of knowledge-intensive entrepreneurship. Starting from the comprehension of the innovative and knowledge-intensive attributes of the entrepreneurship, as driver for the competitiveness of the organizations in the scenario of the knowledge economy, the study aims to deepen which are the opportunities offered by Big Data within an entrepreneurial process. Big data represent an actual field of study, both for the agenda of researchers and practioners, but while a growing set of works are concentrated on the comprehension of the technological dimensions of the phenomenon, its application in the field of entrepreneurship is still in infancy. Focusing on this last endeavor, the paper aims to provide an interdisciplinary contribution at the debate on big data by demonstrating how the large amount of knowledge distributed in the web and mainly around the social network platforms can allow the conception of an entrepreneurial process more aligned with the customers’ needs and focused on the actual market’s trends. Based on a qualitative review of an interdisciplinary literature, the paper will provide empirical evidences on the applications of Big Data for the effective realization of knowledge-intensive entrepreneurship in the field of the tourism.

title: Big Data to Monitor Big Social Events: Analysing the mobile phone signals in the Brescia Smart City

description: We present the rst experience, carried out in 2013, devoted to the ex-traction of geo-referenced statistical information from mobile phone signalsto monitor big social events in Brescia, a mid-sized city located near Milan(Lombardy, Italy). The statistical analysis is based on the Telecom ItaliaCityLive database, used to dene raster structures and space-time proleswith the R open source language. The obtained results for the two big eventsheld in Brescia in 2013 (the car race \Mille Miglia" and the bicycle race \Girod'Italia") have proved very useful to this municipal administration to planfuture events, and more generally to develop policies for the \smart city".

title: Big Data or Big Fail? The Good, the Bad and the Ugly and the missing role of Statistics

description: The so called “Big Data” are data which we think as being “big” because of their volume, their amount per unit of time and because they are un- structured. The usual sources of big data are administrative repositories, transaction data or social media and social network feeds. Someone defines big data as those data which cannot be analyzed on a desktop machine or stored on one’s hard disk. These ways of defining big data completely miss the point of view of Statistics: they seem to be tailored more to advertising campaign of SaS or storage solution rather than to Science. Moreover, recent big fails, like e.g. the famous/infamous Google Flu Trend experiment, raised a series of popular news paper articles against the validity of information contained in these data and Statistics itself, even though none of these bad practices has been conducted by statisticians. While Information Technol- ogy and Computer Science are good at efficiently retrive and manage them, these data should be soon brought back into the field of Statistics to where data belong and this Special Issues of EJASA is one important step in this direction.

title: Ontological analysis for dynamic data model exploration

description: Increasing access to data and computational resources allows use to use more expressive approaches to data analysis. We propose using established statistical metrics to assist the automatic analysis of free text transcripts. The meaningful concepts from a domain and their axiomatic relationships can be captured in an ontology. This provides an aggregate model which describes the domain. However, the fine detail from individual elements and their characteristics are subsumed by the whole.  Keeping multiple 'micro models' of the data, along with meta information allows a range of different view points. This can be applied to free text documents that within a domain where significant information is carried by one or a few instances such as in the analysis of interview transcripts. This paper presents a framework that utilises ontological tools to create domain models in a way that it allows for a distributed and parallel implementation necessary for big data analysis.

title: Implementation of a Training Courses Recommender System based on k-means algorithm

description: Providing the right professional training courses for employees is a critical issue for organizations as well as employees. Its necessity stemmed out on the fulfillment of the organization and employees need. Thus, building a recommender system that would help in the decision making process and planning of the training course offered by organizations. This can be performed using various techniques and methodologies, where the most important one is data mining. Data mining is a process of looking for specific patterns and knowledge from large databases and carrying out predictions for outputs. Therefore, this project aims to build a web-based application for predicting appropriate training recommenders for Princess Norah University employees based on their education and professional information. This helps the university in suggesting the most optimal training recommender for employees, which in turn can enhance their performance and develop their career and working levels.

Employees’ data was gathered from the Human Resource of the university and then clustered using the WEKA program to find the centroids of clusters to be then used in the developed application. The developed web-based application is used to suggest the most suitable training recommender for each employee. Results demonstrate that the developed web-based application effectively suggests the most appropriate training courses for employees based on the previously taken courses, evaluation of courses and probability for promotion. Furthermore, this web-based application can be used for describing the appropriate training courses for new employees based on their levels. The achieved accuracy of the developed system was 73.33%.

title: Data Envelopment Analysis (DEA) for the evaluation of Public Healthcare Structures.

description: As stated in the Economist Intelligence Unit report (2011), the failure to
develop a coherent plan of action in health care systems is linked to deeprooted problems related to the organization of health care structures. These problems form the starting point of this work: the aim of the present study is to develop the potential of a Data Envelopment Analysis (DEA) Model creating a non-parametric pattern for evaluating the eciency of healthcare structures in a south-eastern region of Italy. A non-parametric pattern allows for weighting dierent variables even in the presence of a particularly complex structure, such as that of healthcare systems. The results will provide some indications for health decision and policy makers, in order to improve accountability in the eld of Social Responsibility, of particular relevance in this moment.

title: Designing a decision support system for stock exchange selection based on serious games simulation

description: A model for designing of decision support system is a simulation that induces reality and uses different models to describe the complex reality. It also concerns uncertainty and can help users to achieve a conceptual and detailed description of the reality. Serious game is being used as a tool for developing model for a long time. Producing serious games simulation environments is one of the best options in data collection, trial and error, and learning and decision-making for the investment markets that rapid change of the rate increases the risk. A virtual system will provide better aid by using actual data foe a better management of the financial resources and offer options for users at every level of decision. Entering the stock market is possible for everyone but the possibility of selecting a stock portfolio that results in achieving a good profit is very difficult and hard, due to rapidly changing customer markets is becoming more difficult. That is it's a high-risk environment for investors. Indeed people do not have sufficient experience and training in this field. Indeed all people don't have sufficient experience and training in this field. The goal is designing a simulated environment that is similar to the stock for the brokers and enthusiasts to help them to choose an appropriate portfolio. Moreover it should have an interactive graphical environment that even novice users can find the necessary training in this area. Creating a Simulation environment in serious games requires rebuilding and finding the principles and a framework that not only involves the world standard hay accepted by experts in the field but also, according to Iran's investment conditions, becomes localized and in practice, will be efficient.

title: Graded Algebras, Polynomial Identities and Generic Constructions

description: In these lecture we present some results which intertwine topics as graded algebras, polynomial identities and algebras of generic elements. Some of these connection are classical and well known to different communities (e.g. crossed produts, Galois cohomology, algebra of generic matrices, general group gradings on finite dimensional algebra). Some other connection among these topics are relatively new where these are realized via the theory of group graded polynomial identities. In particular, using (G-graded) asymptotic PI theory, we outline the proof of a conjecture of Bahturin and Regev on regular gradings on associative algebras. These lectures took place in Porto Cesareo, Italy. The author is mostly grateful to the organizers of the meeting Advances in Group theory.

title: Products of groups which contain abelian subgroups of finite index

description: It is unknown whether every group G = AB which is the product of of two abelian-by-finite subgroups A and B must always have a soluble or even metabelian subgroup of finite index. Here we deal with the special case of this problem when A and B contain abelian subgroups of "small" index, notably of index at most 2. Some recent results on the solubility of such groups are discussed which depend on special calculations involving involutions.
