Texto completoResumen
The topic of this paper is the concept of originality as it relates to the concept of genesis developed by Deleuze in his early essay ‘The Idea of Genesis in Kant's Esthetics’. Using the exhibition of Tim Bennett's as a starting point, it brings together two accounts of originality, the first postmodern one represented by Rosalind Krauss's ‘The Originality of the Avant-garde’ and the second genetic kind found in Deleuze's aforementioned essay, to show how originality and genesis might correspond, paying close attention to the transcendental innovations of Kant's aesthetic tradition to which both concepts belong.

DNA polymorphism has been studied, indicators of genetic diversity and genetic originality have been de-termined for three natural populations and three replacement broodstocks of sterlet (Acipenser ruthenus Linnaeus, Acipenseridae) from the Volga Federal District. In the group of A. ruthenus replacement broodstock, 106 ISSR-PСR markers were identified, and in the group of natural populations, 103 ISSR-PСR markers. The indicators of genetic diversity and the coefficient of genetic originality (CGO) were slightly higher in the group of natural populations. Analysis of genetic structure of natural populations and groups of broodstock herds A. ruthenus showed that the coefficient of genetic differentiation are also slightly higher in the group of natural populations and equal 0,377. As a result of molecular genetic iden-tification, generic and species identification fragments of sterlet DNA were revealed, as well as combina-tions of polymorphic fragments for identification of the studied natural populations and stocks. The data obtained can be used to preserve the gene pool of populations, which is characteristic for a particular re-gion.

Texto completoResumen
In order to carry out activities aimed at conservation and rational use of forest resources; it is necessary to study the main forest-forming plant species in detail. Scots pine (Pinus sylvestris L., Pinaceae) is mainly found in the boreal forests of Eurasia and is not so often encountered in the east of the East European Plain. The aim of the study was to study the genetic diversity, structure and differentiation of Scots pine populations in the east of the East European Plain. We studied ten populations of P. sylvestris using the Inter Simple Sequence Repeats (ISSR)-based DNA polymorphism detection method. Natural populations are demonstrated by relatively high rates of genetic diversity (He = 0.167; ne = 1.279; I = 0.253). At the same time, there is a tendency for a decrease in the genetic diversity of the studied populations of P. sylvestris from west to east. Analysis of the genetic structure shows that the studied populations are highly differentiated (GST = 0.439), the intrapopulation component accounts for about 56% of the genetic diversity. Using various algorithms for determining the spatial genetic structure, it is found that the studied populations form two groups of populations in accordance with geographic location. With the help of a genetic originality coefficient, populations with specific and typical gene pools are identified. They are recommended as sources of genetic diversity and reserves for the conservation of genetic resources of the species.

Texto completoResumen
A molecular genetic analysis of horologically related populations of Pinus sylvestris L. was carried out. In the east and northeast of the East European Plain using intermicrosatellite analysis of DNA polymor-phism. Data on the genetic diversity of populations were obtained and the state of their gene pools was assessed. The studied populations of Scots pine have a high genetic diversity (P95= 0.938, HЕ= 0.170, ne= 1.540). Of the 144 DNA fragments, only 3 (0.021%) are rare. The analysis of the share of rare alleles showed that the genetic structure is less balanced in the populations of Verkhnevetluzhskaya (h= 0.254) and Vetluzhsko-Vyatka (h= 0.273). The most balanced genetic structure was observed in the Moloma population (h=0.112) and in the North Vyatka-Uvala population (h=0.127). When assessing the state of gene pools, it was found that the highest values of the coefficient of genetic originality (CSR) were found in the populations of Sysolo-Vychegodskaya (1,164) and Volga-Vetluzhskaya (1.140). This indicates the high specificity of the gene pools of these populations. The lowest values of CLO were determined in the Vetluzhsko-Vyatskaya (0.857) and Volzhsko-Surinskaya (0.875) populations. Analysis of all three groups of indicators of the state of gene pools of populations showed that, taking into account the genetic structure and genetic originality, 6 populations of P. sylvestris have a satisfactory state of gene pools, and two populations (Verkhnevetluzhskaya and Vetluzhsko-Vyatka) have depleted gene pools. When selecting trees for conservation and reforestation, it is necessary to preserve populations with both typical and specific gene pools.

Purpose – Stock selection has long been identified as a challenging task. This line of research is highly contingent upon reliable stock ranking for successful portfolio construction. The purpose of this paper is to employ the methods from computational intelligence (CI) to solve this problem more effectively. Design/methodology/approach – The authors develop a risk-adjusted strategy to improve upon the previous stock selection models by two main risk measures – downside risk and variation in returns. Moreover, the authors employ the genetic algorithm for optimization of model parameters and selection for input variables simultaneously. Findings – It is found that the proposed risk-adjusted methodology via maximum drawdown significantly outperforms the benchmark and improves the previous model in the performance of stock selection. Research limitations/implications – Future work considers an extensive study for the risk-adjusted model using other risk measures such as Value at Risk, Block Maxima, etc. The authors also intend to use financial data from other countries, if available, in order to assess if the method is generally applicable and robust across different environments. Practical implications – The authors expect this risk-adjusted model to advance the CI research for financial engineering and provide an promising solutions to stock selection in practice. Originality/value – The originality of this work is that maximum drawdown is being successfully incorporated into the CI-based stock selection model in which the model's effectiveness is validated with strong statistical evidence.

Purpose The purpose of this paper is building the regression model related to tool wear, and the regression model is used to identify the state of tool wear. Design/methodology/approach In this paper, genetic programming (GP), which is originally used to solve the symbolic regression problem, is used to build the regression model related to tool wear with the strong regression ability. GP is improved in genetic operation and weighted matrix. The performance of GP is verified in the tool vibration, force and acoustic emission data provided by 2010 prognostics health management. Findings In result, the regression model discovered by GP can identify the state of tool wear. Compared to other regression algorithms, e.g. support vector regression and polynomial regression, the identification of GP is more precise. Research limitations/implications The regression models built in this paper can only make an assessment of the current wear state with current signals of tool. It cannot predict or estimate the tool wear after the current state. In addition, the generalization of model has some limitations. The performance of models is just proved in the signals from the same type of tools and under the same work condition, and different tools and different work conditions may have influences on the performance of models. Originality/value In this study, the discovered regression model can identify the state of tool wear precisely, and the identification performances of model applied in other tools are also excellent. It can provide a significant information about the health of tool, so the tools can be replaced or repaired in time, and the loss caused by tool damage can be avoided.

Texto completoResumen
The article "The originality of Chinoiserie-style garden architecture in England in the XVIII century" explores the development and specifics of Chinoiserie style in the landscape architecture of England. Chinoiserie style refers to the use of Chinese motifs and stylistic techniques in European architecture. The aim of the work is to identify the specifics of the arrangement of English gardens and parks in the Chinoiserie style. The subject of the study is the stylistic features of the embodiment of Chinoiserie gardens and parks. The object of the study is parks and garden architecture in the Chinoiserie style in England. The study covers the 18th century, revealing the contribution of individual architects and the influence of Chinese art on the development of garden architecture. The presented analysis demonstrates how architectural styles of Western and Eastern culture can mix. English gardens and parks are evidence of the influence of Chinese aesthetics on landscape gardening, which later spread to continental Europe. In the course of the research, the following methods were mainly used: historical, historical-genetic, historical-comparative. In the study of specific objects of landscape architecture, methods of art criticism analysis were applied — formal, stylistic and comparative methods. The article examines specific English monuments of landscape architecture of the XVIII century taken as examples the Chinoiserie style. The novelty of the study lies in the fact that the features of the Chinoiserie style in the landscape architecture of England were highlighted and a comparison of English architectural objects in the Chinoiserie style with Chinese analogues was carried out. The conducted research revealed the English specifics in the approach to interpreting Chinese designs of gardens and parks and architectural projects in the XVIII century. English gardeners and architects were inspired by Chinese aesthetics and used oriental elements for decoration, but did not follow all architectural canons and traditions. This gave rise to a new Chinoiserie style, a combination of Chinese and European landscape art that spread throughout Europe.

Purpose The purpose of this paper is to present a scale for measuring internal integration within human resource management (HRM) departments, which is developed and validated in this paper. Thus far, no valid, comprehensive operational instrument for measuring HRM internal integration has been introduced in the literature. Design/methodology/approach The scale items were developed on the basis of a qualitative analysis. The authors recruited 233 HRM professionals from 29 organizations to participate in the survey. In this paper, the authors present evidence of content validity, internal consistency reliability and construct validity that provides support for the use of an HRM internal integration scale. Exploratory factor analysis was conducted to determine the underlying factors that comprise HRM internal integration, while confirmatory factor analysis was used as a confirmatory test of the scale. Findings The results of this study led to the development of a standardized 34-item instrument that can be used for measuring HRM internal integration. Originality/value The use of the scale opens up a new research avenue by focusing on the nature of integration processes, particularly within HRM systems. The scale will allow studies to be compared across various contexts.

Purpose Deception detection is instrumental in business management but professionals differ widely in terms of deception detection performance. The purpose of this paper is to examine the genetic basis of deception detection performance using the classic twin study design and address the research question: how much variance in individual differences in deception detection performance can be accounted for by the variance in genetics vs environmental influences? Design/methodology/approach In total, 192 twins, with 65 pairs of monozygotic (identical) twins and 31 pairs of dizygotic (fraternal) twins participated in an experiment. A series of behavioral genetic analyses were performed. Findings The variability in deception detection performance was largely determined by differences in shared and non-shared environments. Research limitations/implications The subjects were solicited during the Twins Days Festival so the sample selection and data collection were limited to the natural settings in the field. In addition, the risks and rewards associated with deception detection performance in the study are pale in comparison with those in practice. Practical implications Deception detection performance may be improved through training programs. Corporations should continue funding training programs for deception detection. Originality/value This is the first empirical study that examines the complementary influences of genetics and environment on people’s ability to detect deception.

Purpose – The purpose of this paper is to formulate the reliability optimization problem in stochastic and interval domain and also to solve the same under different stochastic set up. Design/methodology/approach – Stochastic programming technique has been used to convert the chance constraints into deterministic form and the corresponding problem is transformed to mixed-integer constrained optimization problem with interval objective. Then the reduced problem has been converted to unconstrained optimization problem with interval objective by Big-M penalty technique. The resulting problem has been solved by advanced real coded genetic algorithm with interval fitness, tournament selection, intermediate crossover and one-neighbourhood mutation. Findings – A new optimization technique has been developed in stochastic domain and the concept of interval valued parameters has been integrated with the stochastic setup so as to increase the applicability of the resultant solution to the interval valued nonlinear optimization problems. Practical implications – The concept of probability distribution with interval valued parameters has been introduced. This concept will motivate the researchers to carry out the research in this new direction. Originality/value – The application of genetic algorithm is extended to solve the reliability optimization problem in stochastic and interval domain.

Purpose – Value-at-risk (VaR) is a risk measure of potential loss on a specific portfolio. The main uses of VaR are in risk management and financial reporting. Researchers are continuously looking for new and efficient ways to evaluate VaR, and the 2008 financial crisis has given further impetus to finding new and reliable ways of evaluating and using VaR. In this study, the authors use genetic algorithm (GA) to evaluate VaR and compare the results with conventional VaR techniques. Design/methodology/approach – In essence, the authors propose two modifications to the standard GA: normalized population selection and strict population selection. For a typical set of simulation, eight chromosomes were used each with eight stored values, and the authors get eight values for VaR. Findings – The experiments using data from four different market indices show that by adjusting the volatility, the VaR computed using GA is more conservative as compared to those computed using Monte Carlo simulation. Research limitations/implications – The proposed methodology is designed for VaR computation only. This could be generalized for other applications. Practical implications – This is achieved with much less cost of computation, and hence, the proposed methodology could be a viable practical approach for computing VaR. Originality/value – The proposed methodology is simple and, at the same time, novel that could have far-reaching impact on practitioners.

Purpose The purpose of this paper is to establish the value of clinical genetic diagnostics in the lives of people with an intellectual disability (ID), their families, and their primary and professional caregivers. It has been shown that psychologists are more likely to make use of the opportunities offered by clinical genetic diagnostics if they have seen the psychological benefits in their own practice. Moreover, this paper aims to promote the practice of informing people with ID, their families, and other caregivers regarding the current technological advances in genetic diagnostics, thereby allowing these patients to decide for themselves whether to utilise these opportunities. Design/methodology/approach The authors report four case studies in which the psychosocial value to each patient is pivotal. Findings In these four cases, it is clear the medical model can augment the social model by providing an interpretation of its meaningfulness in the lives of the people concerned. Research limitations/implications Case studies alone can have limited scientific significance. This approach examining the significance of clinical genetic diagnosis should be studied further in larger groups. Practical implications It is hoped that psychologists and other professional caregivers will become enthused about the value of clinical genetic diagnostics and will choose to discuss the option of referral for clinical genetic diagnostics with their patients more often. Social implications People with an ID who are seeking mental health care, and their caregivers, should be given the opportunity to take part in the decision regarding whether to use clinical genetic diagnostics, which may even have a destigmatising effect. Originality/value Quality of life may improve for people with an ID seeking mental healthcare and for their caregivers as well by opening up discussion regarding the opportunities presented by clinical genetic diagnostics. The fact that people are able to make their own choices based on their own considerations can have a destigmatising effect.

Purpose The purpose of the paper is to design a robust control system for a generic hypersonic vehicle which includes dynamic nonlinear, open loop unstable and parametric uncertainties. Design/methodology/approach For a complex longitudinal model of a generic hypersonic vehicle which includes dynamic nonlinear, open loop unstable and parametric uncertainties, a nonlinear dynamic inverse (NDI) approach combined with proportional differential (PD) control is used to design a strong robust control system to deal with the sensitivity to changes of atmosphere condition. In this way, a simple genetic algorithm is used to search a group of parameters of the control system to satisfy the specific performance indices. Then parametric uncertainties are considered to verify the robustness of the control system. Findings The PD hypersonic vehicle control system using NDI approach can satisfy the specific flight performance. And it has strong robustness under the parametric uncertainties. Originality/value The paper fulfills a complete process of the nonlinear control system design for a generic hypersonic vehicle. And, the simulation results show the efficiency and robustness of the control system.

Previous studies on the genetic basis of creativity have mainly focused on the biological mechanisms of divergent thinking, possibly limiting the exploration of possible candidate genes. Taking a cognition-based perspective, the present study investigated the genetic basis for both the divergent and the convergent thinking components of creativity. A total of 321 Chinese university students were recruited to complete the Guildford Unusual Using Test (UUT) for divergent thinking capability and the Remote Associates Test (RAT) for convergent thinking capability. The polymorphism of rs2576037 in KATNAL2 was related to the fluency and originality component scores of UUT, and the polymorphism of rs5993883 in COMT, rs362584 in SNAP25 was related to the RAT performance. These effects remained significant after considering the influence of age, gender and intelligence. Our results provide new evidence for the genetic basis of creativity and reveal the important role of gene polymorphisms in divergent and convergent thinking.

Findings – The experimental results suggest that the proposed KGA is feasible and available. The effective integration of GA model and knowledge model has greatly improved the optimization performance of KGA. Originality/value – The technological innovation of complex products is one of effective approaches to establish the core competitiveness in future. For this reason, the KGA is proposed to the technological processes optimization of complex products.

Purpose In this paper, the previously developed idea of generalized optimization of circuits for deterministic methods has been extended to genetic algorithm (GA) to demonstrate new possibilities for solving an optimization problem that enhance accuracy and significantly reduce computing time. Design/methodology/approach The disadvantages of GAs are premature convergence to local minima and an increase in the computer operation time when setting a sufficiently high accuracy for obtaining the minimum. The idea of generalized optimization of circuits, previously developed for the methods of deterministic optimization, is built into the GA and allows one to implement various optimization strategies based on GA. The shape of the fitness function, as well as the length and structure of the chromosomes, is determined by a control vector artificially introduced within the framework of generalized optimization. This study found that changing the control vector that determines the method for calculating the fitness function makes it possible to bypass local minima and find the global minimum with high accuracy and a significant reduction in central processing unit (CPU) time. Findings The structure of the control vector is found, which makes it possible to reduce the CPU time by several orders of magnitude and increase the accuracy of the optimization process compared with the traditional approach for GAs. Originality/value It was demonstrated that incorporating the idea of generalized optimization into the body of a stochastic optimization method leads to qualitatively new properties of the optimization process, increasing the accuracy and minimizing the CPU time.

Purpose The purpose of this paper is to find optimal reef parameters to minimize the maximum instantaneous opening load for a reefed parachute with geometry and environmental parameters given in the model. Design/methodology/approach The dynamic model Drop Test Vehicle Simulation (DTVSim) is used to model the inflation and descent of the reefed parachute system. It is solved by the fourth-order Runge–Kutta method, and the opening load values are thereby obtained. A parallel genetic algorithm (GA) code is developed to optimize the reefed parachute. A penalty scheme is used to have the maximum dynamic pressure restricted within a certain range. Findings The simulation results from DTVSim fit well with experimental data from drop tests, showing that the simulator has high accuracy. The one-stage and two-stage reefed parachute systems are optimized by GA and their maximum opening loads are decreased by 43 and 25 per cent, respectively. With the optimal reef parameters, two of the peaks in the opening load curve are almost equal. The velocity, loiter time and flight path angle of the parachute system all change, but these changes have no negative effect on the parachute’s operational performance. Originality/value An optimization method for reefed parachute design is proposed for the first time. This methodology can be used in the preliminary design phase for a reefed parachute system and significantly improve design efficiency.

Texto completoResumen
Among the epic genres of Ukrainian folklore, duma occupies a special place. Genetically connected with such traditional genres as bylina (epic story), lamentation, spell and other earlier varieties of folk oral poetry, it spreads mainly in the 17th and 18th centuries. However, later, it continues to exist in folklore and actively influences the literary process that can be vividly observed in the works by Taras Shevchenko and other writers of the 19th century. Contemporary authors productively employ and develop characters, motifs and style profoundness of this ancient genre. Genesis of duma to our time remains an actual problem. Its persistence in the tradition of Kievan Rus culture has been pointed out by M. Maksymovych, M. Hrushevsky and other researchers. The poetics of dumas, particularly their artistic structure, has been explored quite substantially, although this research is far from exhaustive. What strikes one’s eye right from the first acquaintance with dumas is the non-strophic composition. This uninhibited verse flow, as if not limited by anything, distinctively echoes an unceasing flow of life. Resembling the dynamics of recreated highly dramatic events, it contributes to emotional expressiveness, as well as to meditative reflections of their poetic comprehension. At the same time, F. Kolessa, followed by other researchers, noticed more or less detached periods (tirades, fragments) of this generally free non-strophic flow. These periods clearly represent a specific structure of such verse. They principally have quite an appreciable prosodic tint in a musical text, and also their own specifics in a verbal text. This specificity — primarily by the example of concrete works — is expected to become the subject matter of thorough research. A subtle combination of long and shorter lines, alternation between diverse regular rhythms and no less diverse rhythms of a free, often queer nature — all this gives a particular vividness to the texts of dumas. These are the evidence of that uniqueness, which was discussed by T. Shevchenko in regard to Ukrainian duma, and to which many researchers drew our attention. However, this unquestionable uniqueness doesn’t contradict the genetic and typological bond of Ukrainian folk dumas and world epic tradition.

Texto completoResumen
Purpose – The purpose of this paper is to suggest a definition of genetic information by taking into account the debate surrounding it. Particularly, the objections raised by Developmental Systems Theory (Griffiths, 2001; Oyama 1985; Griffiths and Knight 1998) to Teleosemantic endorsements of the notion of genetic information (Sterelny et al. 1996; Maynard Smith, 2000; Jablonka, 2002) as well as deflationist approaches which suggest to ascribe the notion of genetic information a heuristic value at most, and to reduce it to that of causality (Godfrey-Smith, 2000; Boniolo, 2003, 2008). Design/methodology/approach – The paper presents the notion of genetic information through its historical evolution and analyses it with the conceptual tools offered by philosophical theories of causation on one side (“causation as influence,” Woodward, 2010; Waters, 2007; Lewis, 2000) and linguistics on the other (“double articulation” Martinet, 1960). Findings – The concept of genetic information is defined as a special kind of cause which causes something to be one way rather than another, by combining elementary units one way rather than another. Tested against the notion of “genetic error” this definition demonstrates to provide an exhaustive account of the common denominators associated with the notion of genetic information: causal specificity; combinatorial mechanism; arbitrariness. Originality/value – The definition clarifies how the notion of information is understood when applied to genetic phenomena and also contributes to the debate on the notion of information, broadly meant, which is still affected by lack of consensus (Floridi, 2013).

Findings – The paper has shown that the processing time of the proposed idea is practically negligible in applications and also shown that an optimal solution can be obtained even with a single stuck-at fault or a transient fault, and that increasing the number of parallel threads makes the system less susceptible to faults. Originality/value – The study described in this paper is a new approach to increase the sustainability of application program using distributed GA on GPUs and MCPs.

The minimization of the makespan of the job shop problem with J jobs and M machines is NP-hard problem. To resolve it we apply a genetic algorithm [1,2]. We use a real coding for the representation of chromosomes. The originality of our variant lies by the choice of two effective crossover operators and one for mutation, As well as their respective probability, determined by numeric simulations on several examples known in the literature. We compare our results on ''OR library'' benchmarks [3] with Adamas and al. [4], Ombuki and al [5] and Yamada and al [6] results.

The article is devoted to the work of the Danish film director T. Winterberg. The aim of the article is to study the plot originality of the stories told by T. Winterberg by methods of cinema, to understand the genre specificity of his films, highlighting the experiment as the most significant component of their artistic and mental originality. Descriptive, hermeneutic, diachronic, historical-genetic, comparative, analytical and biographical methods, used in a complex manner, allow one to come to certain conclusions. These conclusions are that T. Winterberg's cinematography relies on experiment as a way of plotting, which determines the genre character of the director's films. This is confirmed by the luck that accompanied exactly those films of T. Winterberg, which are built on Danish material, and the much less success of films created on plots that are associated with other toposes (Soviet, American, British). T. Winterberg became world famous after the release of the film "Family Celebration", made within the framework of such originally Danish phenomenon as «Dogma-95». Collation of the author's manner of T. Winterberg with the master of Danish (and world) cinema and originator of «Dogma» L. von Trier allows us to compare the ways of organizing the narrative of two famous film directors: if L. von Trier's films are based on provocation, then T. Winterberg – exactly on experiment. Being rooted on national soil, this experiment transcends ethnic narrow-mindedness itself, acquiring a universal, between-national character.

Purpose Genetic knowledge is advancing steadily while at the same time DNA sequencing prices are dropping fast, but the diffusion of genetic services (GS) has been slow. The purpose of this paper is to identify GS diffusion drivers in the precision medicine (PM) ecosystem. Design/methodology/approach After reviewing the literature on innovation diffusion, particularly on GS diffusion, the PM ecosystem actors are interviewed to obtain their perspective. Using content analysis, the interviewees’ visions were interplayed with the literature to achieve driver conceptualization, which posteriorly originated broad themes. Findings The results indicate that GS diffusion depends on satisfying aspects from three broad themes and respective drivers: technology (evidence strength and credibility, customization, knowledge, data and information, tech evolution speed and cost), human (ethics, privacy and security and user power) and business (prevention, holistic view of the individual, public policy and regulation, business model and management). Practical implications The main management implications refer to considering health care in a multidisciplinary way, investing in the propagation of genetic knowledge, standardizing medical records and interpreting data. Originality/value This study, to the best of authors’ knowledge, is the first attempt to understand GS diffusion from a broad perspective, taking into account the PM stakeholders’ view. The 13 drivers offer a comprehensive understanding of how GS could spread in health care and they can assist researchers and practitioners to discuss and set strategies based on an initial structured map.

Purpose – Many studies have proposed variant fuzzy time series models for uncertain and vague data. The purpose of this paper is to adapt a fuzzy time series combined with genetic algorithm (GA) to forecast tourist arrivals in Taiwan. Design/methodology/approach – Different cases are studied to understand the effect of variation of fuzzy time series order, number of intervals and population size on the fitness function which decreases with increase in fuzzy time series order and number of fuzzy intervals, but do not have marginal effect due to change in population size. Findings – Results based on an example of forecasting Taiwan’s tourism demand was used to verify the efficacy of proposed model and confirmed its superiority to existing models providing solutions for different orders of fuzzy time series, number of intervals and population size with a smaller forecasting error as measured by root mean square error. Originality/value – This study provides a viable forecasting methodology, adapting a fuzzy time series combined with an evolutionary GA. The proposed hybridized framework of fuzzy time series and GA, where GA is used to calibrate fuzzy interval length, is flexible and replicable to many industrial situations.

Texto completoResumen
Background: Genetic control is necessary at all stages of forest selection for the effective use of objects of unified genetic-selection complex (UGSC). This is particularly important for performing a breeding inventory. The aim of the present study was to evaluate the genetic variability of trees of different selection categories in several plus stands of Scots pine.
Materials and methods: 116 trees of Scots pine of various selection categories have been selected from four plus stands within the middle taiga subzone of Karelia. The analysis of the pine samples had been performed using four nuclear SSR loci tests. DNA fragments were separated on a sequencer CEQ 8000. The main criteria of the genetic diversity and F-statistics were calculated. The genetic structure of the selection groups was evaluated using the coefficient of genetic originality (CGO).
Results: All the selection groups evaluated with CGO were characterized by a low content of alleles, which are rare for this part of the Scots pine areal. The plus trees were characterized by a reduced level of genetic diversity (Ho = 0.480.59; He = 0.470.59) as compared to minus (Ho = 0.460.64; He = 0.490.65) and normal trees (Ho = 0.500.69; He = 0.490.65). However, the observed differences between the breeding groups were not statistically significant.
Conclusion: The absence of significant differences between the selection groups indicates the need of a separate assessment of the genetic and economic value of plus trees according to their phenotype. The obtained data is necessary for the organization of objects of UGSC, testing of clonal and seed offspring of plus trees, certification of clones, etc.

Purpose The purpose of this paper is to present a modified version of the non-dominated sorted genetic algorithm with an application in the design optimization of a power inductor for magneto-fluid hyperthermia (MFH). Design/methodology/approach The proposed evolutionary algorithm is a modified version of migration-non-dominated sorting genetic algorithms (M-NSGA) that now includes the self-adaption of migration events- non-dominated sorting genetic algorithms (SA-M-NSGA). Moreover, a criterion based on the evolution of the approximated Pareto front has been activated for the automatic stop of the computation. Numerical experiments have been based on both an analytical benchmark and a real-life case study; the latter, which deals with the design of a class of power inductors for tests of MFH, is characterized by finite element analysis of the magnetic field. Findings The SA-M-NSGA substantially varies the genetic heritage of the population during the optimization process and allows for a faster convergence. Originality/value The proposed SA-M-NSGA is able to find a wider Pareto front with a computational effort comparable to a standard NSGA-II implementation.

Purpose The purpose of this paper is to present a new technique for the determination of effective criteria weight on satisfaction using genetic algorithm and fuzzy synthetic evaluation. Design/methodology/approach The weight values express the relative importance of criteria. In most of research works, weight values depend heavily on expert knowledge, and customer’s perspective have not been considered. The proposed approach determines the criteria weight on satisfaction using genetic algorithm and fuzzy synthetic evaluation considering Euclidean distance between the computed overall satisfaction evaluation and the surveyed overall satisfaction evaluation. Findings The research findings show that different segments of customer have various needs and explain causes of various needs in customers using genetic algorithm and fuzzy synthetic evaluation. Originality/value The value of the paper is in it using a new approach in order to determine the weight of criteria. The main advantage of proposed approach is that it will help managers and researchers to determine the weight of criteria on satisfaction, and this process will no longer just rely on expert knowledge.

Purpose – In this study, the hybrid Taguchi genetic algorithm (HTGA) was used to optimize the computer numerical control-printed circuit boards drilling path. The optimization was performed by searching for the shortest route for the drilling path. The number of feasible solutions is exponentially related to the number of hole positions. The paper aims to discuss these issues. Design/methodology/approach – Therefore, a traveling cutting tool problem (TCP), which is similar to the traveling salesman problem, was used to evaluate the drilling path; this evaluation is considered an NP-hard problem. In this paper, an improved genetic algorithm embedded in the Taguchi method and a neighbor search method are proposed for improving the solution quality. The classical TCP problems proposed by Lim et al. (2014) were used for validating the performance of the proposed algorithm. Findings – Results showed that the proposed algorithm outperforms a previous study in robustness and convergence speed. Originality/value – The HTGA has not been used for optimizing the drilling path. This study shows that the HTGA can be applied to complex problems.

Purpose The purpose of this paper is to present a new technique to portfolio selection using a genetic algorithm (GA) and fuzzy synthetic evaluation (FSE). Portfolio selection is a multi-objective/criteria decision-making problem in financial management. Design/methodology/approach The proposed approach solves the problem in two stages. In the first stage, by using a GA and FSE, the weight of criteria will be calculated. Euclidean distance between the computed overall performance evaluation and the surveyed overall performance evaluation is used to determine the weight of criteria. In the second stage, by using a GA and FSE, portfolios will be prioritized. A multi-objective GA is used to determine return and risk in the efficient frontier. A decision making approach is based on FSE to select the best portfolio from among the solutions obtained by a multi objective GA. Findings The main advantage of the proposed approach is to help an investor to find a portfolio which has best performance, and portfolio selection does not rely on expert knowledge. Originality/value The value of the paper is in it using a new approach to determine the weight of criteria and portfolio selection. It surveys firms’ performance in the stock market, based on which the weight of criteria will be determined and portfolios will be prioritized.

The purpose of this paper is to discuss two recent studies on dyslexia that shed light on either genetic or environmental causes. Design/methodology/approach One study was a thorough exploration of possible genetic differences that could be present in children experiencing reading and language difficulties. The other study examined a large sample of the Canadian public to see whether there was a link between dyslexia and having experienced physical abuse as a child or teenager. Findings The study on genetic differences found no evidence for some previously suggested genetic causes of dyslexia. Although previous studies have suggested dyslexia runs in families, the genetic contribution may have been overestimated. The study on the Canadian public found that people who reported experiencing physical abuse in their younger years were six to seven times more likely also to have a diagnosis of dyslexia. Childhood trauma is known to affect brain development. Originality/value Although this paper only discusses two papers in detail, they are two of the most recent explorations of genetic and environmental links to dyslexia. There could be a case for greater attention to possible traumatic experiences in children identified as dyslexic. Physical abuse is one possibility but should never be assumed. Families can be under strain and may need more support. However, dyslexia and the mental health difficulties that can result from childhood trauma can reduce a child’s current and future social inclusion. Early intervention may avert this outcome.

Establishing sustainable plantations with genetic diversity equivalent to that of natural populations is vital for successful reforestation efforts. In this study, we present an innovative approach for selecting populations suitable for reforestation, taking into account their genetic uniqueness using Inter Simple Sequence Repeats (ISSR) markers. Our investigation focused on six populations of Picea obovata Ledeb and six populations of Larix sibirica Ledeb, collected from the Northern and Middle Urals. We found that the indicators of genetic diversity were significantly higher in L. sibirica compared to P. obovata, while the number of rare alleles was greater in Siberian spruce (R = 19). Among the P. obovata populations, the Cherdyn’s forestry exhibited notably high genetic diversity, and for L. sibirica, the Gainy’s forestry stood out in this regard. Moreover, the genetic subdivision of the six P. obovata populations (GST = 0.331) was higher than that of the six L. sibirica populations (GST = 0.177). To ensure optimal seed selection considering the genetic originality coefficient (GOC) and population differentiation, we recommend utilizing the P. obovata population from Gainy’s forestry with a GOC of 0.554 and the L. sibirica population from Cherdyn’s forestry with a GOC of 0.372. These populations harbor typical alleles characteristic of the research region, making them ideal candidates for seed selection. Furthermore, the specific alleles identified can serve as valuable markers for determining the geographic origin of P. obovata and L. sibirica wood, aiding in efforts to trace the sources of these species in forestry and trade practices.

Neoplasia occurs as a result of genetic mutations. Research evaluating the association between gene mutations and skin cancer is limited and has produced inconsistent results. There are no established guidelines for screening skin cancer at molecular level. It should also be noted that the combinations of some mutations may play a role in skin tumors’ biology and immune response. There are three major types of skin cancer, and the originality of this study comes from its approach of each of them.

The appearance of A. Pushkin and the evolution of N. Gogol, M. Lermontov, F. Dostoevsky, A. Chekhov, M. Zoshchenko, E. Zamyatin of the type of “little man” is considered, its originality in the work of each of the writers is revealed. The genetic connections of Gogol’s “St. Petersburg” stories with Hoffmann’s prose are revealed, the image of Bashmachkin is interpreted in the context of L. Shestov’s ideas, and some interpretations of the “little man” type in modern Russian literary criticism are evaluated.

The social and political views of A.I. Solzhenitsyn represent an organic part of the Russian free conservatism tradition that emerged after the French Revolution and matured after the 1812 due to N.M. Karamzin, V.A. Zhukovsky, A.S. Pushkin, F.I. Tyutchev, and their successors. The clear “consonance” of the ideas of A.I. Solzhenitsyn and his predecessors in the Russian tradition of the conservative originality is expressed in their rejection of imitation of Western culture and in the direct “genetic” relationship of their ideas.

Purpose This paper aims to innovatively propose to improve the efficiency of satellite observation and avoid the waste of satellite resources, a genetic algorithm with entropy operator (GAE) of synthetic aperture radar (SAR) satellites’ task planning algorithm. Design/methodology/approach The GAE abbreviated as GAE introduces the entropy value of each orbit task into the fitness calculation of the genetic algorithm, which makes the orbit with higher entropy value more likely to be selected and participate in the remaining process of the genetic algorithm. Findings The simulation result shows that in a condition of the same calculate ability, 85% of the orbital revisit time is unchanged or decreased and 30% is significantly reduced by using the GAE compared with traditional task planning genetic algorithm, which indicates that the GAE can improve the efficiency of satellites’ task planning. Originality/value The GAE is an optimization of the traditional genetic algorithm. It combines entropy in thermodynamics with task planning problems. The algorithm considers the whole lifecycle of task planning and gets the desired results. It can greatly improve the efficiency of task planning in observation satellites and shorten the entire task execution time. Then, using the GAE to complete SAR satellites’ task planning is of great significance in reducing satellite operating costs and emergency rescue, which brings certain economic and social benefits.
