A two-component copula with links to insurance
Authors: Ismail S. , Yu G. , Reinert G. , Maynard T. 
Published: December 2017

Abstract
This paper presents a new copula to model dependencies between insurance entities, by considering how insurance entities are affected by both macro and micro factors. The model used to build the copula assumes that the insurance losses of two companies or lines of business are related through a random common loss factor which is then multiplied by an individual random company factor to get the total loss amounts. The new two-component copula is not Archimedean and it extends the toolkit of copulas for the insurance industry.
Determinants of Critical Infrastructure Resources
Authors: Ostrowska Teresa , Krupa Tadeusz 
Published: December 2017

Abstract
This article is devoted to the issue of how resources are interpreted in the form of technology reactors that, as a result of unexpected circumstances, turn into pyramidal or avalanche threat dynamics. Counteracting such catastrophic, terrorist, or war situations cannot begin in the face of mass casualties or significant material losses that will require reconstruction and the work of many generations. The decisive factor is the correct long-term operation and management of the economy. The starting point of this article is the concept of resource and structural-functional relationships of resources and all their possible interpretations consistent with the functionalities they play in the human environment, human aggregates, and whole nations. The aim is to draw the reader's attention to the importance (semiotics) of qualitative specifications and dynamically changing determinants contained in the material and structural-functional properties of the resources and their channel (information) communication.

Published: December 2017

AbstractPhysical activity plays a crucial role in bone mass acquisition during childhood and adolescence, with weightbearing and high-impact sport activities being more beneficial. This study sought to evaluate the impact of different sports activities on bone mineral density and content in male Portuguese athletes. Seventy adolescent boys (aged 12-15 years) including 28 futsal players (FG), 20 swimmers (SG) and 22 non-athletic adolescents used as control subjects (CG), participated in the current study. Areal bone mineral density (aBMD) and areal bone mineral content (aBMC) were measured by dual energy x-ray absorptiometry (DEXA). Futsal players had significantly higher aBMD (lumbar spine - FG: 0.95 ± 0.18, SG: 0.80 ± 0.13, CG: 0.79 ± 0.13 g/cm2,p= 0.001; pelvis - FG: 1.17 ± 0.21, SG: 0.91 ± 0.12, CG: 0.98 ± 0.10 g/cm2,p< 0.001; lower limbs - FG: 1.21 ± 0.19, SG: 0.97 ± 0.10, CG: 0.99 ± 0.09 g/cm2,p< 0.001) and aBMC (lumbar spine - FG: 51.07 ± 16.53, SG: 40.19 ± 12.47, CG: 40.50 ± 10.53 g,p= 0.013; pelvis - FG: 299.5 ± 110.61, SG: 170.02 ± 55.82, CG: 183.11 ± 46.78 g,p< 0.001; lower limbs - FG: 427.21 ± 117.11, SG: 300.13 ± 76.42, CG: 312.26 ± 61.86 g/cm2,p< 0.001) than swimmers and control subjects. Data suggest that futsal, as a weightbearing and high or odd-impact sport, may improve bone mass during childhood and adolescence.

Abstract
This study determined whether a multivariate profile more effectively discriminated selected than non-selected elite youth Brazilian soccer players. This examination was carried out on 66 youth soccer players (selected, n = 28, mean age 16.3 ± 0.1; non-selected, n = 38, mean age 16.7 ± 0.4) using objective instruments. Multivariate profiles were assessed through anthropometric characteristics, biological maturation, tactical-technical skills, and motor performance. The Student’s t-test identified that selected players exhibited significantly higher values for height (t = 2.331, p = 0.02), lean body mass (t = 2.441, p = 0.01), and maturity offset (t = 4.559, p < 0.001), as well as performed better in declarative tactical knowledge (t = 10.484, p < 0.001), shooting (t = 2.188, p = 0.03), dribbling (t = 5.914, p < 0.001), speed – 30 m (t = 8.304, p < 0.001), countermovement jump (t = 2.718, p = 0.008), and peak power tests (t = 2.454, p = 0.01). Forward stepwise discriminant function analysis showed that declarative tactical knowledge, running speed –30 m, maturity offset, dribbling, height, and peak power correctly classified 97% of the selected players. These findings may have implications for a highly efficient selection process with objective measures of youth players in soccer clubs.

Published: December 2017

Abstract
The Relative Age Effect (RAE) in sport has been targeted by many research studies. The objective of this study was to analyze, in amateur clubs, the RAE of soccer players, according to the sport expertise level of the team (e.g., A, B, C and subsequent) that they belong to within the same game category. 1,098 soccer players in formative stages took part in the study, with ages varying between 6 and 18 years old (U8 to U19 categories). All of them were members of 4 Spanish federated clubs. The birth dates were classified into 4 quartiles (Q1 = Jan-Mar; Q2 = Apr-Jun; Q3 = Jul-Sept; Q4 = Oct-Dec)according to the team they belonged to. The results obtained in the chi-squared test and d value (effect size) revealed the existence of RAE in the teams with the highest expertise level, “A” (X2 = 15.342, p = .002, d = 0.4473) and “B” (X2 = 10.905, p = .012, d = 0.3657). However, in the lower level teams, “C and subsequent”, this effect was not observed. Present findings show that players born during the first months of the year tend to be selected to play in teams with a higher sport expertise level of each category, due to their physical maturity. Consequently, this causes differences in terms of the experience they accumulate and the motivation that this creates in these players.

Published: December 2017

Abstract
The aim of this study was to perform an electromyographic and kinetic comparison of two commonly used hamstring eccentric strengthening exercises: Nordic Curl and Ball Leg Curl. After determining the maximum isometric voluntary contraction of the knee flexors, ten female athletes performed 3 repetitions of both the Nordic Curl and Ball Leg Curl, while knee angular displacement and electromyografic activity of the biceps femoris and semitendinosus were monitored. No significant differences were found between biceps femoris and semitendinosus activation in both the Nordic Curl and Ball Leg Curl. However, comparisons between exercises revealed higher activation of both the biceps femoris (74.8 ± 20 vs 50.3 ± 25.7%, p = 0.03 d = 0.53) and semitendinosus (78.3 ± 27.5 vs 44.3 ± 26.6%, p = 0.012, d = 0.63) at the closest knee angles in the Nordic Curl vs Ball Leg Curl, respectively. Hamstring muscles activation during the Nordic Curl increased, remained high (>70%) between 60 to 40° of the knee angle and then decreased to 27% of the maximal isometric voluntary contraction at the end of movement. Overall, the biceps femoris and semitendinosus showed similar patterns of activation. In conclusion, even though the hamstring muscle activation at open knee positions was similar between exercises, the Nordic Curl elicited a higher hamstring activity compared to the Ball Leg Curl.

Published: December 2017

Abstract
There is a large gap in knowledge regarding research on post-exercise blood changes in disabled athletes. There are relatively few data on adaptive mechanisms to exercise in disabled athletes, including disabled rowers. Two rowers from a Polish adaptive rowing settle TAMix2x that qualified for the Paralympic Games in Rio, 2016 took part in this study. They performed a progressive test on a rowing ergometer until exhaustion. The cardiorespiratory fitness measures, complete blood count, white blood cells’ distribution and 30 clinical chemistry variables describing laboratory diagnostic profiles and general health were determined. The extreme effort induced changes in all studied metabolites (glucose, creatinine, urea, uric acid, total and direct bilirubin), albumin, total protein levels in both participants. Furthermore, a post-exercise increase in aspartate transaminase activity, yet a 2-fold decrease during the recovery time in both rowers were found. White blood cell count increased 2-fold after the test. The percentages of natural killer cells were higher and total T lymphocytes were lower after the exercise protocol. There were higher percentages of suppressor/cytotoxic and lower percentages of helper/inducer T lymphocyte subsets in both studied rowers. No changes in B lymphocytes distribution were observed. Lack of inflammatory symptoms during the experiment suggests a high level of rowers’ biological adaptation to the physical effort. The different changes in physiological, biochemical and immunological variables are related to the adaptive mechanism to physical exercise allowing for improvement of performance.

Authors: O’Brien B. , Hennessy D. 
Published: December 2017

AbstractThe Irish dairy industry is critically important to the economy and general well-being of a large section of the Irish population. Its quality, sustainability and maintenance are the key for a vibrant rural society in the future. Two important elements for the future of this industry include (a) the quality, marketing and sale of dairy products on the export market and (b) sustainability from the perspectives of people, planet and profit. This paper provides a short review of current scientific evidence in relation to a number of topics, each of which is important in maintaining and developing dairy product quality and the sustainability of the Irish dairy industry. The topics addressed in the paper are as follows: the parameters of milk composition; milk processing; hygiene quality and safety; farm management practices and the regulations that govern such practices; animal health and welfare; environmental impacts; economic implications for farm families and rural communities; and the overall future sustainability of the family-based dairy farm structure.
A review of laser electrode processing for development and manufacturing of lithium-ion batteries
Authors: Pfleging Wilhelm 
Published: December 2017

AbstractLaser processes for cutting, annealing, structuring, and printing of battery materials have a great potential in order to minimize the fabrication costs and to increase the electrochemical performance and operational lifetime of lithium-ion cells. Hereby, a broad range of applications can be covered such as micro-batteries, mobile applications, electric vehicles, and stand-alone electric energy storage devices. Cost-efficient nanosecond (ns)-laser cutting of electrodes was one of the first laser technologies which were successfully transferred to industrial high-energy battery production. A defined thermal impact can be useful in electrode manufacturing which was demonstrated by laser annealing of thin-film electrodes for adjusting of battery active crystalline phases or by laser-based drying of composite thick-film electrodes for high-energy batteries. Ultrafast or ns-laser direct structuring or printing of electrode materials is a rather new technical approach in order to realize three-dimensional (3D) electrode architectures. Three-dimensional electrode configurations lead to a better electrochemical performance in comparison to conventional 2D one, due to an increased active surface area, reduced mechanical tensions during electrochemical cycling, and an overall reduced cell impedance. Furthermore, it was shown that for thick-film composite electrodes an increase of electrolyte wetting could be achieved by introducing 3D micro-/nano-structures. Laser structuring can turn electrodes into superwicking. This has a positive impact regarding an increased battery lifetime and a reliable battery production. Finally, laser processes can be up-scaled in order to transfer the 3D battery concept to high-energy and high-power lithium-ion cells.
Surface-enhanced FAST CARS: en route to quantum nano-biophotonics
Authors: Voronine Dmitri V. , Zhang Zhenrong , Sokolov Alexei V. , Scully Marlan O. 
Published: December 2017

AbstractQuantum nano-biophotonics as the science of nanoscale light-matter interactions in biological systems requires developing new spectroscopic tools for addressing the challenges of detecting and disentangling weak congested optical signals. Nanoscale bio-imaging addresses the challenge of the detection of weak resonant signals from a few target biomolecules in the presence of the nonresonant background from many undesired molecules. In addition, the imaging must be performed rapidly to capture the dynamics of biological processes in living cells and tissues. Label-free non-invasive spectroscopic techniques are required to minimize the external perturbation effects on biological systems. Various approaches were developed to satisfy these requirements by increasing the selectivity and sensitivity of biomolecular detection. Coherent anti-Stokes Raman scattering (CARS) and surface-enhanced Raman scattering (SERS) spectroscopies provide many orders of magnitude enhancement of chemically specific Raman signals. Femtosecond adaptive spectroscopic techniques for CARS (FAST CARS) were developed to suppress the nonresonant background and optimize the efficiency of the coherent optical signals. This perspective focuses on the application of these techniques to nanoscale bio-imaging, discussing their advantages and limitations as well as the promising opportunities and challenges of the combined coherence and surface enhancements in surface-enhanced coherent anti-Stokes Raman scattering (SECARS) and tip-enhanced coherent anti-Stokes Raman scattering (TECARS) and the corresponding surface-enhanced FAST CARS techniques. Laser pulse shaping of near-field excitations plays an important role in achieving these goals and increasing the signal enhancement.

What Lies Underneath a Political Speech?: Critical Discourse Analysis of Thai PM’s Political Speeches Aired on the TV Programme Returning Happiness to the People
Authors: Carreon Jonathan Rante , Svetanant Chavalin 
Published: December 2017

Abstract The main goal of the study is to critically investigate the major elements of the political speeches of the Thai Prime Minister, Gen Prayuth Chan-ocha. Informed by van Dijk’s (1997) concept of Political Discourse Analysis, a corpus, composed of 10,672 word types and 325,398 word tokens, was examined for keywords related to the addressor, the addressee, and the political speech itself. The words with the highest relative frequencies were iteratively categorised into themes and a dialogic investigation was conducted on a portion of the original Thai version. The findings reveal that keywords relating to information conveyed by the addressor accounted for 62.86% (N=154) followed by keywords relating to functions of language at 22.04% (N=54). The high frequencies of these words shed light on the justification of the political, economic and social agenda, which were conveyed by the junta government using deontically modalised language. The quantitative and qualitative data analysis also indicate that the English and Thai speeches target different audiences. This discrepancy implicitly reflects an awkward situation where the military government attempts to present a good image to the international community while imposing actual military governance in the country.
The relationship between self-control and altruism in the light of discounting literature
Authors: Osiński Jerzy , Karbowski Adam , Rusek Jan 
Published: December 2017

Abstract
On the basis of literature on delay discounting, potential mechanisms of relations between self-control and altruism are considered. The discussed possibilities are: cause-and-effect relationship (self-control enabling sacrificing immediate benefits caused by selfish behaviour in favor of future benefits associated with altruism, e.g. reciprocation), common mechanism (ability to learn behavioural patterns covering longer time periods), role of intelligence as a factor related both to self-control and altruism, and role of psychological distance (the idea of extended self and construal level theory). Relations between described perspectives are pointed out, and directions for further research are suggested.
Overlapping defaults. The case of intertemporal choices
Authors: Sawicki Przemysław , Białek Michał 
Published: December 2017

Abstract
People make different choices depending on which decision is the default option. In intertemporal choices, the default option is typically imposed externally. For example, people expect more for delaying the gain (default in the present) than are willing to pay for accelerating the future gain over the same period (default in the future). We claim that apart from the external default, people’s choices are also influenced by the internal (natural) default such as the time perspective resulting in the reference point in the present. By manipulating the congruency between the internal and external defaults, we show that incongruence between defaults decreases the strength of discounting of gains, but not of losses.

Published: December 2017

AbstractThis study aimed to analyze the explanatory contribution of social responsibility and organizational justice on commitment through the setting up of a theoretical model in order to better understand the relationships that are established between these constructs. The empirical study was developed in a public higher education institution with a sample of 233 employees, professors and staff. The proposed model was estimated using a structural equation model. It was possible to observe a relationship between interactional justice perceptions and social responsibility and there contribute to the explanation of organizational affective commitment. At the same time, it was possible to observe a relationship between distributive justice and social responsibility of employees.
Measurement issues of the social class in social psychology of education: Is it a category mistake?
Authors: Sinha Chetan 
Published: December 2017

Abstract
The present article discusses the measurement of social class in the social psychology of education research. It was evident that social class experiences are conflated with the socioeconomic status (SES) indicators and the subjective measure of the class context was underrepresented. However, this was discussed in Rubin et al (2014) about the intersectional nature of social class taking into account both objective and subjective indicators. The derivation of the social class experience from the objective and subjective measures were critically discussed. An effort was made to understand whether these translations are category mistake or not. Three trajectories will be utilized to address the category mistake, that is, 1) subjectivity and objectivity debate in the measurement of social class in social psychology of education, 2) debates encircling around the position of social psychology and its underutilized concept such as social class as scientifically objective facets in social sciences and 3) operationalism of social class and category mistake.
A simple model of production and trade in an oligopolistic market: back to basics
Authors: Lahiri Somdeb 
Published: December 2017

Abstract
We provide a two good model of oligopolistic production and trade with one good being commodity money. There is the usual demand function of the consumers for the produced good that producer-sellers face. Each seller is a budget constrained preference maximizer and derives utility (or satisfaction) from consuming bundles comprising commodity money and the produced good. We define a competitive equilibrium strategy profile and a Cournotian equilibrium and show that under our assumptions both exist. We further show that at a competitive equilibrium strategy profile, each seller maximizes profits given his own consumption of the produced good and the price of the produced good, the latter being determined by the inverse demand function. Similarly we show that at a Cournotian the sellers are at a Cournot equilibrium given their own consumption of the produced good. Assuming sufficient differentiability of the cost functions we show that at a competitive equilibrium each seller either sets price equal to marginal cost or exhausts his capacity of production; at a Cournotian equilibrium each seller either sets marginal revenue equal to marginal cost or exhausts his capacity of production. We also study the evolution of Cournotian strategies as the sellers and buyers are replicated. As the number of buyers and sellers go to infinity any sequence of interior symmetric Cournotian equilibrium strategies admits a convergent subsequence, which converges to an interior symmetric competitive equilibrium strategy. In a final section we discuss the Bertrand Edgeworth price setting game and show that a Bertrand Edgeworth equilibrium must be a derived from a competitive equilibrium price. Here we show that if at a symmetric competitive equilibrium, the sellers consume positive quantities of the produced good then the competitive equilibrium cannot be a Bertrand Edgeworth equilibrium. Thus, if at all symmetric competitive equilibria the sellers consume positive amounts of the produced good, then a Bertrand Edgeworth equilibrium simply does not exist.
