Potential Fit between Geotechnical Tasks and Mobile Computing Technologies
Authors: Shehzad Aamer , Zaidi Abd Rozan Mohd 
Published: July 2018

Trend of rapid pace in earthworks has forced geotechnical laboratories to increase their productivity and performance at organizational as well as at individual level. Though geotechnical work involves numerous mobile work processes but the true potential of rapidly growing mobile computing technologies (MCT) has not yet been effectively exploited mainly due to lack of realization of a potential match between features of this specific technological paradigm and major task requirements. To fill this gap, this study investigated and characterized salient task characteristics and features of MCT. Based on the theory of task-technology fit (TTF), an initial conceptual model is proposed which reflects hypothesized relationships for finding a fit between task and technology and consequently assessing its impact on performance of geotechnical field workers. This paper contributes to the knowledge pool of information system through development of an adapted TTF model in geotechnical mobile work context. Lastly, future research plan of using quantitative methodology for finding empirical support of this conceptual model is presented.

Published: July 2018

School refusal is one of the main problems observed in almost all levels of education in Turkey. This problem is characterized by difficulties in going to school, staying at school for an entire day or not feeling well at school. School refusal is commonly associated with cognitive evaluations and emotional problems, and it may also be a source for various other problems. The purpose of this study is to do a research about the predictor power of depression, negative thoughts and attachment styles in school refusal through the sample of Turkish students. Furthermore, the school refusal behavior has also been analysed in terms of some demographical variables such as gender, perceived socio-economic level, and parents’ educational level. The study group consisted of 340 secondary school students studying in Istanbul. School Refusal Assessment Scale-R, The Revised Child Anxiety and Depression Scale-Short Version, The Experiences in Close Relationships Middle Childhood, and Three Dimensions of Cognitive Scale were used as measurements. Results have indicated that school refusal is predicted by anxiety, depression and negative thoughts but is not predicted by attachment styles such as avoidance and anxiety attachment. The results have been presented and discussed in the light of the literature.

Podejście to pozwala na wyróżnienie dwóch perspektyw analizy spójności komunikatu multimodalnego: paralelnej oraz sekwencyjnej. Umożliwia także porównanie stopnia spójności różnych typów komunikatów multimodalnych oraz przewidywanie wpływu zmian poziomu spójności na przetwarzanie komunikatu. Proponowany model daje możliwość analizy spójności zarówno z punktu widzenia odbiorcy, jak i nadawcy komunikatu.
The Choice of Effect Measure for Binary Outcomes: Introducing Counterfactual Outcome State Transition Parameters
Authors: Huitfeldt Anders , Goldstein Andrew , Swanson Sonja A. 
Published: July 2018

Abstract
Standard measures of effect, including the risk ratio, the odds ratio, and the risk difference, are associated with a number of well-described shortcomings, and no consensus exists about the conditions under which investigators should choose one effect measure over another. In this paper, we introduce a new framework for reasoning about choice of effect measure by linking two separate versions of the risk ratio to a counterfactual causal model. In our approach, effects are defined in terms of counterfactual outcome state transition parameters, that is, the proportion of those individuals who would not have been a case by the end of follow-up if untreated, who would have responded to treatment by becoming a case; and the proportion of those individuals who would have become a case by the end of follow-up if untreated who would have responded to treatment by not becoming a case. Although counterfactual outcome state transition parameters are generally not identified from the data without strong monotonicity assumptions, we show that when they stay constant between populations, there are important implications for model specification, meta-analysis, and research generalization.
The Effect of Foreign Equity Ownership on Corporate Social Responsibility: Empirical Evidence from Poland
Authors: Doś Anna 
Published: July 2018

Abstract
In the literature on corporate social responsibility (CSR) the origin of the equity is seen as one the drivers of CSR. There is evidence of multinational corporations stimulating diffusion of CSR practices in a few emerging economies. There are no similar studies focusing on the Polish economy. Since CSR practices are country-specific it is important to investigate if and how capital flows foster corporate social responsibility among firms established and operating in Poland. The method applied in the study is a statistical analysis of the ownership structure of firm whose socially responsible practices are highly ranked by the independent think-tanks compared to the ownership structure of their most relevant competitors. The results allow for a more comprehensive understanding of CSR drivers in Poland as well as the role of foreign capital in reshaping economic structures in Poland.
Factors influencing green strength of commercial natural rubber
Authors: Thi Thuong Nghiem , Trung Nghia Phan , Kawahara Seiichi 
Published: July 2018

Abstract
The factors influencing the green strength of commercial solid rubbers were investigated in the present study through characterization of commercial natural rubber (NR). Various solid commercial rubbers such as standard Vietnam rubber (SVR10), standard Indonesia rubber (SIR10), India standard natural rubber (ISNR10), ribbed smoked sheets (RSS3), and FNR (commercial Sumitomo Rubber) were used as a source. Purification of the samples was carried out through acetone extraction and purified samples were characterized by nuclear magnetic resonance (NMR) and Fourier-Transform infrared spectroscopy. Degradation was found for SVR10, ISNR10, and SIR10 but not for RSS3 and FNR through the assignment of 13C-NMR signals. Acetone extraction was found to improve the green strength of commercial NR due to the removal of impurities. Linked fatty acids and proteins contributed to the upturn of stress at small strain. However, the network structure of degraded rubbers had an insignificant role in enhancing the green strength of commercial NR.

Published: July 2018

Abstract
To meet the demand for carbon-fibre-reinforced composites in lightweight applications, cost-efficient processing and new raw materials are sought for. Cellulose and kraft lignin are each interesting renewables for this purpose due to their high availability. The molecular order of cellulose is an excellent property, as is the high carbon content of lignin. By co-processing cellulose and lignin, the advantages of these macromolecules are synergistic for producing carbon fibre (CF) of commercial grade in high yields. CFs were prepared from precursor fibres (PFs) made from 70:30 blends of softwood kraft lignin (SW-KL) and cellulose by dry-jet wet spinning with the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([EMIm][OAc]) as a solvent. In focus was the impact of the molecular mass of lignin and the type of cellulose source on the CF yield and properties, while membrane-filtrated kraft lignin and cellulose from dissolving kraft pulp and fully bleached paper-grade SW-KP (kraft pulp) served as sources. Under the investigated conditions, the yield increased from around 22% for CF from neat cellulose to about 40% in the presence of lignin, irrespective of the type of SW-KL. The yield increment was also higher relative to the theoretical one for CF made from blends (69%) compared to those made from neat celluloses (48–51%). No difference in the mechanical properties of the produced CF was observed.

Authors: Osafo Newman , Obiri David D. , Antwi Aaron O. , Yeboah Oduro K. 
Published: July 2018

Abstract

Background
Our earlier studies had given evidence of the traditional application of Xylopia aethiopica in the management of inflammation. The principal constituent obtained from its bio-fractionation is xylopic acid. It is a crystalline diterpene that belongs to the class of kauranes. This work sets out to investigate the anti-inflammatory potential of the xylopic acid isolated from the dried fruit of X. aethiopica.

Methods
A preliminary anti-inflammatory study, using the protein denaturation model, and in vivo anti-inflammatory assay were employed in the investigation of acute inflammation. The modulation of the effect of the pro-inflammatory markers histamine, serotonin, bradykinin, and prostaglandin E2 by xylopic acid was investigated by in vivo mice paw oedema models.

Results
Xylopic acid showed a concentration-dependent inhibition of albumen denaturation with an IC50 of 15.55 μg mL−1. Xylopic acid (10, 30, 100 mg kg−1) inhibited the maximal oedema and the average paw thickness (oedema) over the period of each study considerably for all phlogistic agents employed (i.e. carrageenan, histamine, serotonin, bradykinin, and prostaglandin E2) in the inflammation induction for both prophylactic and therapeutic protocols.

Conclusion
This study establishes that xylopic acid has anti-inflammatory action in acute inflammation.

The paper seeks a point of view on developments in the current operational environment, focusing on the review of the military operations typology in identifying potential measures to counteract the actions of the hybrid war and highlighting the need for a new approach to the construction of armed power in terms of new types risks, challenges and threats
The Intercultural Dimension of Military Action for Combating Hypothetical Adversaries
Authors: Tudorache Paul , Ispas Lucian 
Published: July 2018

Abstract
Defining and analyzing the current typology of threats determines the military structures to operationally and, implicitly, organizationally adapt in order to ensure their ability to deter and combat hypothetical opponents in any operational environment. From the point of view of efficiency and effectiveness of action, it is no longer sufficient to engage the joint and multinational military structures alone, inter agency and intergovernmental action approaches being necessary. On these grounds, the intercultural dimension of the action of the military structures undergoes changes, moving from the internal plan, of the inter force relationships in the organic structure of the multinational military force into the external one, defined by the interactions between the latter and the structures/forces/elements within other agencies, intergovernmental organizations, to which the local population is added
Planning and Time Management
Authors: Dimitrova Vanya , Mancheva-Ali Olga 
Published: July 2018

Abstract
For the fulfilment of any plan or task, the management decisions need time: from several hours to several years. Therefore a special place in planning takes time management, establishing effective use of the staff time and each employee, which is divided into business and personal time. Time is the only resource that is not reproduced, it can’t be overtaken, but you can lag behind it. The task that is not completed within the established timeframe must be completed in the next term, assigned for another task, or at the expense of personal time. Planning and time management or organizing time is a technology to organize and improve the effective use of time
The Impact of the Case-Law of the Court of Justice of the European Union in the Field of Public Procurement
Authors: Ivanova Albena 
Published: July 2018

AbstractThe article examines the case-law of the Court of Justice of the European Union on Public Procurement issues. On the one hand, the paper analyzes the control exercised by the Court in this area while the Member States implement the Public Procurement Directives by transposing them into national law or by administrative practice which is subject to judicial review. The Court's control is executed through the interpretation of provisions and through actions taken by the European Commission against Member States for breaches of EU law in the area of Public Procurement. On the other hand, in the references for a preliminary ruling, the Court of Justice of the EU defines some basic terms, such as 'public procurement' (at Union level), a contractor, a minimum threshold, etc., and affirms the key principles that must be respected for the fulfilment of Public Procurement objectives such as transparency, competition and equal treatment. The article aims to show the contribution of the case-law of the Court of Justice of the European Union to the development and uniform application of Public Procurement legislation in the Member States and facilitates the functioning of the Internal market

The Role of Public Authorities During Mobilization
Authors: Stoian Alexandru 
Published: July 2018

Abstract
Imposed by states in order to defend its own territory and national values during the time of crisis, mobilization of armed forces in a contemporary global context creates new challenges for the public authorities, designers of the national legal framework and for the military authorities. In this regard, extraordinary measures can be taken in political, economic, social, administrative, diplomatic, legal and military fields, planned and prepared in peacetime. The Romanian National Defense System consists of the forces intended for defense, the resources of the national defense and the territorial infrastructure and provides a stable foundation for all types of actions related to mobilization, as long as the procedures involved are implemented at a high level of efficiency
The Visual Message. Directions of Evolution in Image Advertising
Authors: Ilie Oana-Antonia 
Published: July 2018

Abstract
The advertising image has become a part of our daily life; it is the main method of marketing in society, which encourages and finally, persuades people to purchase goods and services. A picture is worth a thousand words, and the visual image has gained supremacy over all other communication means. Advertising contributes to the development of the economy by increasing demand and by sustaining economic activities. It determines people to consume more and thereby improves their standard of living. The brand images are capable of instantly catching consumers’ attention and are the influential devices that make people aware of the quality of a product. As a resistance movement, the adbusters assumed the mission to reveal the true face of the advertising message, and thus express disapproval of those who hunt their potential buyers so aggressively. Advertising experts are competing every year in improving institutions’ image strategies, making them more and more innovative and creative in order to sell their products and services and succeed in their field. Recent statistics confirm that the new marketing trend is all about the visual message. It’s importance is predicted to grow in the following years: an estimated 84% of communications are estimated to be visual by 2018

Alexander the Great and the “Clash” of Ancient Civilizations
Authors: Strechie Mădălina 
Published: July 2018

Abstract
Alexander the Great was not only a great political leader, but also an amazing general. He did not face only armies, but entire civilizations which he forced to merge, following his own example. We believe that his most lasting victory was the Hellenistic civilization, a new civilization that emerged after the “clash of civilizations” that Alexander, the great leader, had opposed, namely the Greek civilization versus the Persian civilization. His war was totally new, revolutionary, both in terms of fighting tactics, weapons, and especially goals. Alexander became the Great because of his ambition to conquer the world from one end to the other. Beginning with the pretext meant to take revenge for the Persian Wars, his expedition to the Persian Empire was in fact a special “clash of civilizations”. With Alexander, the West fully demonstrates its expansionist tendencies, conquering at first an empire and civilization after civilization. Thus, in turn, the Greek crusher of the new half-god of war defeated the Phoenician, Egyptian, Persian civilizations (the coordinator of the empire that initiated for the first time the process of assimilation of the defeated ones, namely Persanization).From the military point of view, Alexander the Great was the initiator of the lightning war, of course mutatis

mutandis, forming a military monarchy within the conquered civilizations, turning for the first time in history, generals into important politicians, we think here of the Diadochi. Alexander the Great forced the limits beyond human possibilities, beyond the map and beyond fate. He is the most original general of history, precisely in his manner of making war and imposing peace, being the toughest “shock of civilizations”
