The mediating effect of English usage on Facebook on the relationship between shyness and English as a foreign language achievement in university students
Authors: Kao Po-Chi 
Published: January 2019

AbstractThe purpose of this study is to examine a conceptualized three-dimensional construct to test whether English usage on Facebook plays a mediating role in the relationships between shyness and English as a foreign language (EFL) achievement. A total of 174 Taiwanese university students who were enrolled in EFL courses participated in this study. When examining the role of English usage on Facebook as a mediator in the relationship between shyness and EFL achievement, I found that English usage on Facebook was negatively associated with shyness, but positively associated with EFL achievement. The results indicated that English usage on Facebook partially mediated the relationship between shyness and EFL achievement. The strength of the mediating effect suggested that English usage on Facebook explained part of the negative relationship between shyness and EFL achievement. The findings may provide valuable and useful information for linguistic and psychological research in pedagogical contexts.
Voluntary Mobility of Employees for Better Job Opportunities Given a Temporary Contract: Insights Regarding an Age-Varying Association Between the Two Events
Authors: Mussida Chiara , Zanin Luca 
Published: January 2019

Abstract
What mechanisms govern the mobility of employees who voluntarily switch employers for better opportunities, given a temporary contract (TC)? We attempt to answer this question by exploring this issue in Southern and Central European countries. We use cross-sectional data from the European Union Statistics on Income and Living Conditions survey for the 2005–2016 period. We estimate a flexible simultaneous equation model for binary responses by assuming the presence of an age-varying association between voluntary mobility and having a TC. After accounting for several socio-demographic and economic variables, we find a nonlinear decreasing relation between age and the outcomes, while we detect heterogeneous nonlinear patterns in the association between voluntary mobility and having a TC across countries. These insights can support policy-makers aiming to promote initiatives that facilitate the professional mobility of employees given a TC for an efficient allocation of human capital in the production system.
Dynamic Analysis of a Composite Structure under Random Excitation Based on the Spectral Element Method

Published: January 2019

Abstract
The application of the composite materials in the aeronautical and aerospace industries has been increasing over the last several decades. Compared to conventional metallic materials, they present better strength to weight and stiffness to weight ratio. However, they can also present a high level of uncertainty, mainly associated with the manufacturing processes. Besides the uncertainty in the composite material parameters, which can play a role in the structural dynamic response, randomness can also be associated with boundary condition and external excitation sources. This paper treats the dynamic analysis of a composite beam under random excitation and uncertainties in the boundary condition. The beam is modelled by the spectral element method, a wave propagation technique. Some numerical examples are used to study the influence of random source on the dynamic behaviour of the composite structure.
Higher-order theorem proving and its applications
Authors: Steen Alexander 
Published: January 2019

Abstract
Automated theorem proving systems validate or refute whether a conjecture is a logical consequence of a given set of assumptions. Higher-order provers have been successfully applied in academic and industrial applications, such as planning, software and hardware verification, or knowledge-based systems. Recent studies moreover suggest that automation of higher-order logic, in particular, yields effective means for reasoning within expressive non-classical logics, enabling a whole new range of applications, including computer-assisted formal analysis of arguments in metaphysics. My work focuses on the theoretical foundations, effective implementation and practical application of higher-order theorem proving systems.
This article briefly introduces higher-order reasoning in general and presents an overview of the design and implementation of the higher-order theorem prover Leo-III. In the second part, some example applications of Leo-III are discussed.
The stochastic model for Global Navigation Satellite Systems and terrestrial laser scanning observations: A proposal to account for correlations in least squares adjustment
Authors: Kermarrec Gael , Neumann Ingo , Alkhatib Hamza , Schön Steffen 
Published: January 2019

Abstract
The best unbiased estimates of unknown parameters in linear models have the smallest expected mean-squared errors as long as the residuals are weighted with their true variance–covariance matrix. As this condition is rarely met in real applications, the least-squares (LS) estimator is less trustworthy and the parameter precision is often overoptimistic, particularly when correlations are neglected. A careful description of the physical and mathematical relationships between the observations is, thus, necessary to reach a realistic solution and unbiased test statistics. Global Navigation Satellite Systems and terrestrial laser scanners (TLS) measurements show similarities and can be both processed in LS adjustments, either for positioning or deformation analysis. Thus, a parallel between stochastic models for Global Navigation Satellite Systems observations proposed previously in the case of correlations and functions for TLS range measurements based on intensity values can be drawn. This comparison paves the way for a simplified way to account for correlations for a use in LS adjustment.

VALSTYBININKAS: PRETENZIJA Į SĄVOKOS ANALIZĘ

The term statesman has got a positive connotation in Western political vocabularies. The situation in Lithuania is different. Peculiarities of politicalprocess lead to devaluation of the term. During the interwar period in Lithuania the term statesman was more often used by right-wing politicians as a reference designating qualitative evaluation of politicians and other stateagents. Statesman got broader meaning and was used more often by Lithuanian emigrants in the USA. The Renaissance of the term was influenced by Anglo-Saxon political and cultural environment, nostalgia of lost statehood and striving to maintain political identity. In Post-Communist Lithuania thanks to historians the term statesman became one of the instruments in political vocabulary. For some political parties this concept is a tool to achieve political power.There are three conceptions of the term statesman – idealistic, realistand administrative-bureaucratic. Proponents of idealistic conception thinkthat statesman has to establish important political principles for future generations, he has to see further and deeper than other political agents, bevirtuous, just and capable of defending the liberal state. Proponents of thisview think that statesman has to be moral authority. Realist conception ofstatesman is based on different understanding of the relationship betweenmorality and politics. Realists are not advocates of immoral politics, but theythink that some circumstances of political life make it necessary to raise therequirements of the state higher than those of morality. Nicollò Machiavelliformulated the idea that state has got its own autonomous foundations ofexistence which are different from those of morality and religion. He formedthe idea that when there is an exceptional situation, statesman has to look to the interests of state and not those of morality. Henry Taylor is the creatorof administrative-bureaucratic conception of statesman. He is of the opinionthat a man who has mastered the art of implementation of political functionscan make a righteous claim to the title of statesman.
POLITIKOS FENOMENOLOGIJA KAIP PLATONIZMO KRITIKA
Authors: Čelutka Simas 
Published: January 2019

The paper examines the phenomenon of politics as a distinctive domain of practical experience, particularly focusing on the analysis of political space and political time. Along with this, other political aspects are taken into account, such as desire and lack, interest, action, deliberation, judgment, fragility, and freedom. Political phenomenology is contrasted with the notion of politics expounded in Plato’s “Republic”, which centres around the famous Analogy of the Cave. According to the Analogy, the fundamental precondition of political knowledge is a deliberate delocalization – a philosopher’s dissociation from all time-bound factors and the existing political reality which is conceived as a prison of unstable, unreliable “shadows”. The paper suggests that the application of platonic Forms to political life is inadequate, because politics is an essentially temporal, fragile realm. Politics is “nourished” by the past and historical precedents, and also by future, through political aims and visions. Therefore, historical prudence, practical experience and intuition are considered of more relevance for a political subject than theoretical definitions and abstractions. It is argued that the phenomenon of politics has its own specific structure of functioning: it has no need to “borrow” any immutable principles from metaphysicians. Metaphysics does not possess an exclusive access to political knowledge. Objections to Platonism are based on the insights of Aristotle, Hannah Arendt, Michael Oakeshott and some other important political thinkers. Aristotle valuably distinguishes between theory and practice, situating politics in the realm of the latter and thus restoring dignity to the “cave-dweller” and his common sense. Arendt skillfully elaborates on the aspects of fragility of a political action, as well as on conceptualizing the experience of freedom as essential to political life. Furthermore, the paper draws heavily on Arendt’s distinction between rational truth and politics. It is argued that the two are mutually incompatible or even in conflict, because politics allows only for opinions and persuasion, whereas the unchangeable rational truth is conceived as coercive in nature. On his part, Oakeshott provides arguments for the importance of prudence and historical understanding, while also criticizing Plato’s “demonstrative” science of politics. These and a few other lines of reasoning are invoked to account for an inappropriateness of using the Cave Analogy for the understanding of politics.
ISTORIJOS DIMENSIJA NEOSCHOLASTINĖJE EUROPOS INTEGRACIJOS SAMPRATOJE
Authors: Šiaudvytienė Elena 
Published: January 2019

The article aims at analyzing the dimension of history in the neo-scholastic conception of the European integration. The research focuses on R. Schuman’s vision of the European integration. He was among the politicians who created the first European communities. His political thought was deeply influenced by the philosophy of the famous French philosopher J. Maritain and the pope Pius XII who both cherished the historical ideal of the European integration, based on the Christian philosophy of history. The main incentive for undertaking this kind of research was the wish to find an alternative intellectual and theoretical position that would not be based on the historicist principles of modernity and enlightenment. Eventually, such position could enhance the poor reflectivity of today`s European integration theory. The analysis of the neo-scholastic European unification idea revealed that all three authors grounded their understanding of history in onto-existential epistemology of Thomism. Its main claim is twofold. First, every historical moment is perceived as a reference to the underlying reality that is not dependent upon historical flow and endows it with spiritual meaning. Second, at the very moment of perceiving the temporal circumstances and grasping their underlying transcendental reality, the moral requirements for the concrete historical moment are discovered. J. Maritain, Pius XII, and R. Schuman withdrew their ideas of European unification and Christian heritage of Europe from this Thomistic conception of history and the onto-existential epistemology. It is sustained that the results of the undertaken analysis can open qualitatively new theoretical perspectives in the European integration theory and thus help to create a more meaningful Europe. First of all, such a non-historicist position of looking at the process of European integration can provide one condition that is necessary for every true scientific enquiry: it can help to create a theoretical distance among the knowing subject and the known reality. Second, the Christian conception of a human person, which was held by J. Maritain, Pius XII, and R. Schuman, is able at least to stimulate the raising of the most fundamental questions about the true nature and goals of European unification. Third, the analysis has demonstrated that the issue of the Christian heritage of Europe is important and cannot be ignored, because it is a historical fact and not only a lofty idea.
LIETUVOS VIEŠOJO ADMINISTRAVIMO POKYČIAI IR EUROPOS SĄJUNGOS POVEIKIS: AGENTŪRIZACIJA IR DEPOLITIZACIJA

The paper compares the actual patterns of agencification and depoliticisation in Lithuania and explains the extent to which the EU contributed to these changes. Based on the transformational approach and theories of public policy process, our framework for analysis links external factors (including the EU’s influence), internal factors and our dependent variables (changes in public administration and the impact of the EU). Our research employs (descriptive and inferential) statistical analysis of data on the organisational changes of Lithuanian agencies and political participation of their managers. Furthermore, it follows a longitudinal approach to observe ‘net changes’ by mapping agencification and politicisation throughout the period 1990–2012.The paper found that the EU made a significant contribution to the establishment of new agencies driven by the exigencies of EU accession, but its impact on the survival of Europeanised agencies was much smaller after enlargement. Changes in the scope of politicisation can be explained by a combination of evolution in the political conditionality of EU membership and wholesale government changes. The differentiated impact of the EU on public administration changes was observed with the management of the Europeanised agencies becoming increasingly professional over time. Overall, the results of our research confirm the stronger and more enduring impact of specific acquis rules in the EU policy domains compared to the much weaker influence of the EU’s political conditionality. Furthermore, it points to the importance of interactions between domestic actors that realise particular beliefs and pursue certain strategies to understanding institutional and policy changes at domestic level.
Survival and Health Care Use After Feeding Tube Placement in Children With Neurologic Impairment
Authors: Nelson Katherine E. , Rosella Laura C. , Mahant Sanjay , Cohen Eyal , Guttmann Astrid 
Published: January 2019

BACKGROUND AND OBJECTIVES:
Children with neurologic impairment (NI) often undergo feeding tube placement for undernutrition or aspiration. We evaluated survival and acute health care use after tube placement in this population.

METHODS:
This is a population-based exposure-crossover study for which we use linked administrative data from Ontario, Canada. We identified children aged 13 months to 17 years with a diagnosis of NI undergoing primary gastrostomy or gastrojejunostomy tube placement between 1993 and 2015. We determined survival time from procedure until date of death or last clinical encounter and calculated mean weekly rates of unplanned hospital days overall and for reflux-related diagnoses, emergency department visits, and outpatient visits. Rate ratios were estimated from negative binomial generalized estimating equation models adjusting for time and age.

RESULTS:
Two-year survival after feeding tube placement was 87.4% (95% confidence interval [CI]: 85.2%–89.4%) and 5-year survival was 75.8% (95% CI: 72.8%–78.4%). The adjusted rate ratio comparing weekly rates of unplanned hospital days during the 2 years after versus before tube placement was 0.92 (95% CI: 0.57–1.48). Similarly, rates of reflux-related hospital days, emergency department visits, and outpatient visits were unchanged. Unplanned hospital days were stable within subgroups, although rates across subgroups varied.

CONCLUSIONS:
Mortality is high among children with NI after feeding tube placement. However, the stability of health care use before and after the procedure suggests that the high mortality may reflect underlying fragility rather than increased risk from nonoral feeding. Further research to inform risk stratification and prognostic accuracy is needed.
A Bayesian Approach to Mixed Gamma Regression Models
Authors: Corrales Marta Lucia , Cepeda-Cuervo Edilberto 
Published: January 2019

Gamma regression models are a suitable choice to model continuous variables that take positive real values. This paper presents a gamma regression model with mixed effects from a Bayesian approach. We use the parametrisation of the gamma distribution in terms of the mean and the shape parameter, both of which are modelled through regression structures that may involve fixed and random effects. A computational implementation via Gibbs sampling is provided and illustrative examples (simulated and real data) are presented.
