One of the characteristics of knowledge workers is their high level of mobility. The cost of labour turnover of these key resources is high in both financial and non financial terms. There is thus a need to understand what the factors are that underpin the retention cognitions of knowledge workers. Data was collected from 306 knowledge workers in full time employment representing a wide range of demographic groupings. The results showed that job satisfaction and organisational commitment do not predict knowledge workers’ proposed future length of service.Factor analysis revealed seven underlying dimensions of retention cognitions. Cluster analysis revealed nine distinct clusters of knowledge workers with regard to their retention cognitions. High levels of individualism, need for challenge and focus on personal development were demonstrated. The implications of these findings are discussed. OpsommingEen van die eienskappe van kenniswerkers is hulle hoë vlak van mobiliteit. Die koste van arbeidsomset van hierdie sleutelbronne is hoog in beide finansiële en nie-finansiële terme. Daar bestaan dus ’n behoefte om die faktore wat onderliggend is aan die retensiekognisies van kenniswerkers te verstaan. Data is ingesamel van 306 kenniswerkers in voltydse diens wat ’n wye reeks demografiese groeperings verteenwoordig. Die resultate dui daarop dat werktevredenheid en organisasieverbondenheid nie die kenniswerkers se verwagte lengte van diens voorspel nie. Faktorontleding het sewe onderliggende dimensies van retensiekognisies blootgelê. ’n Bondelontleding het nege duidelike bondels van kenniswerkers ten opsigte van hulle retensiekognisies onderskei. Hoë vlakke van individualisme, behoefte aan uitdaging en fokus op persoonlike ontwikkeling is aangedui. Die implikasies van hierdie bevindinge word bespreek.

The Cost

The development of a parametric model for the variable portion of the Cost Per Flying Hour (CPFH) of an ‘unknown’ aircraft platform and its application to diverse types of fixed and rotary wing aircraft development programs (F-35A, Su-57, Dassault Rafale, T-X candidates, AW189, Airbus RACER among others) is presented. The novelty of this paper lies in the utilization of a diverse sample of aircraft types, aiming to obtain a ‘universal’ Cost Estimating Relationship (CER) applicable to a wide range of platforms. Moreover, the model does not produce absolute cost figures but rather analogy ratios versus the F-16’s CPFH, broadening the model’s applicability. The model will enable an analyst to carry out timely and reliable Operational and Support (O&S) cost estimates for a wide range of ‘unknown’ aircraft platforms at their early stages of conceptual design, despite the lack of actual data from the utilization and support life cycle stages. The statistical analysis is based on Ordinary Least Squares (OLS) regression, conducted with R software (v5.3.1, released on 2 July 2018). The model’s output is validated against officially published CPFH data of several existing ‘mature’ aircraft platforms, including one of the most prolific fighter jet types all over the world, the F-16C/D, which is also used as a reference to compare CPFH estimates of various next generation aircraft platforms. Actual CPFH data of the Hellenic Air Force (HAF) have been used to develop the parametric model, the application of which is expected to significantly inform high level decision making regarding aircraft procurement, budgeting and future force structure planning, including decisions related to large scale aircraft modifications and upgrades.

Research into sports coaches has identified the valuable role they play concerning social support provided to athletes together with their contribution to social and cultural interactions within both the participation and performance domains. The purpose of the present study was to qualitatively extract and examine the knowledge and on-task cognitions of high-level coaches (HLCs) within strength and conditioning (S and C). Applied cognitive task analysis (ACTA) was used to examine ten HLCs, each purposefully sampled to reflect over eight years of work in full time environments. The analysis of responses demonstrated HLCs engage in a pattern of innovative and diverse thinking, together with adaptability and multilevel planning, designed to promote an inclusive approach from performers, coaches and management. Commonality was demonstrated within the decision making of HLCs during the design of training programs. Communication was another important consideration when connecting with athletes, observing athletes, speaking to the head coach and integrating their approach with others. A confident, flexible approach to adapting to situational demands was evident and supported by the ability to recall and select from a wide range of previously learnt and tested strategies. Evidence is offered for the importance of interpersonal and social factors in HLCs’ relationships with athletes and coaches. The incorporation of strategies to support versatile, dynamic decision making within future S and C coach development materials will support more impactful performances by coaches at all stages of the coaching process.

Transport Mobility

Passenger transport is a basis in the transport system of any country. The task of transport is to provide an opportunity for every person to reach any point of our planet, not only safely, comfortably and quickly, but with little expenses. Aim: the arm of this study is to evaluate dynamics and share of transport expenses in population of the Russian Federation, and to study interrelation between figure of transport expenses of population and its transport mobility, and passenger transport fares. Methods: to achieve the set aim, such common scientific methods as observation, analysis, generalization, and analogy were used. Results: it is noted that transport expenses of the population increase at a slower pace than consumer spending. When considering the factors affecting the transportation costs of the population, it was determined that against the background of decreasing volumes of passenger traffic there is an increase in transportation tariffs. When comparing the indices of passenger tariffs and the consumer price index, a rapid increase in the cost of passenger traffic compared to prices for consumer goods was noted, which makes transport services less accessible to the public. Conclusion: The accelerating pace of life and economic realities today pose to transport companies certain tasks to ensure high speeds. High-speed ground transportation is coming to the fore, one of the types of which is a magnetic-vehicle transport, which, in addition to high speed, has certain advantages, such as safety, comfort, energy efficiency and high throughput. The development of new high-speed modes of transport, including a magnetic-casting, will ensure a high level of transport mobility and, accordingly, the country's economic development.

This study employed Taiwanese women aged ≥18 years as the population and investigated their exercise habits, as well as the behavioral factors affecting such habits. In research on exercise, the relationship between exercise and sex is a crucial topic, and this relationship affects exercise promotion. Women’s exercise habits are influenced by traditional gender ideology, and women have long been excluded and treated unfairly in the realm of exercise. The study data were collected from a representative sample of 1113 Taiwanese women who participated in the 2011 Taiwan Social Change Survey (sixth phase, second wave). After removing missing values, the data of 1028 participants (46.39 ± 16.90 years) were analyzed. The results indicated that nearly half of the women had an exercise habit (48.3%). Those who were older, lived in a city (i.e., an area with a high level of urbanization), had a full-time job, had more favorable self-reported physical condition, and had enough income to meet their daily needs, were more likely to have an exercise habit.

Tidal stream energy, due to its high level of consistency and predictability, is one of the feasible and promising type of renewable energy for future development and investment. Applicability of Blade Element Momentum (BEM) method for modeling the interaction of turbines in tidal arrays has been proven in many studies. Apart from its well-known capabilities, yet there is scarcity of research using BEM for the modeling of tidal stream energy farms considering full scale rotors. In this paper, a real geographical site for developing a tidal farm in the southern coasts of Iran is selected. Then, a numerical methodology is validated and calibrated for the selected farm by analyzing array of turbines. A linear equation is proposed to calculate tidal power of marine hydrokinetic turbines. This methodology narrows down the wide range of turbine array configurations, reduces the cost of optimization and focuses on estimating best turbine arrangements in a limited number of positions.

Abstract. Factorial survey experiments are increasingly used in the social sciences to investigate behavioral intentions. The measurement of self-reported behavioral intentions with factorial survey experiments frequently assumes that the determinants of intended behavior affect actual behavior in a similar way. We critically investigate this fundamental assumption using the misdirected email technique. Student participants of a survey were randomly assigned to a field experiment or a survey experiment. The email informs the recipient about the reception of a scholarship with varying stakes (full-time vs. book) and recipient’s names (German vs. Arabic). In the survey experiment, respondents saw an image of the same email. This validation design ensured a high level of correspondence between units, settings, and treatments across both studies. Results reveal that while the frequencies of self-reported intentions and actual behavior deviate, treatments show similar relative effects. Hence, although further research on this topic is needed, this study suggests that determinants of behavior might be inferred from behavioral intentions measured with survey experiments.

Molecular self-assembly is ubiquitous in nature and has emerged as a new approach to produce new materials in chemistry, engineering, nanotechnology, polymer science and materials. Molecular self-assembly has been attracting increasing interest from the scientific community in recent years due to its importance in understanding biology and a variety of diseases at the molecular level. In the last few years, considerable advances have been made in the use ofpeptides as building blocks to produce biological materials for wide range of applications, including fabricating novel supra-molecular structures and scaffolding for tissue repair. The study ofbiological self-assembly systems represents a significant advancement in molecular engineering and is a rapidly growing scientific and engineering field that crosses the boundaries ofexisting disciplines. Many self-assembling systems are rangefrom bi- andtri-block copolymers to DNA structures as well as simple and complex proteins andpeptides. The ultimate goal is to harness molecular self-assembly such that design andcontrol ofbottom-up processes is achieved thereby enabling exploitation of structures developed at the meso- and macro-scopic scale for the purposes oflife and non-life science applications. Such aspirations can be achievedthrough understanding thefundamental principles behind the selforganisation and self-synthesis processes exhibited by biological systems.

The book; under review provides a valuable account of the issues and factors in managing the irrigation system, and presents a lucid and thorough discussion on the performance of the irrigation bureaucracies. It comprises two parts: the first outlines the factors affecting irrigation performance under a wide range of topics in the first five chapters. In Chapter One, the authors have attempted to assess the performance of the irrigation bureaucracies, conceptualise irrigation management issues, and build an empirical base for analysis while drawing upon the experience of ten country cases in Asia, Africa, and Latin America. The Second Chapter focuses on the variations in the management structures identified and the types of irrigation systems; and it defines the variables of the management structures. The activities and objectives of irrigation management are discussed in Chapter Three. The objectives include: greater production and productivity of irrigation projects; improved water distribution; reduction in conflicts; greater resource mobilisation and a sustained system performance. The authors also highlight the performance criterion in this chapter. They identify about six contextual factors which affect the objectives and the performance of irrigation, which are discussed in detail in Chapter Four. In Chapter Five, some organisational variables, which would lead to improvements in irrigation, are examined.

The article presents the genetic characteristic of the Chukchi reindeer breed. The object of the study was of the Chukchi reindeer. In recent years, the number of reindeer of the Chukchi breed has declined sharply. Reduced reindeer numbers could lead to biodiversity loss. The Chukchi breed of deer has good meat qualities, has high germination viability and is adapted in adverse tundra conditions of Yakutia. Herding of the Chukchi breed of deer in Yakutia are engaged only in the Nizhnekolymsky district. There are four generic communities and the largest of which is the agricultural production cooperative of nomadic tribal community «Turvaurgin», which was chosen to assess the genetic processes of breed using microsatellite markers: Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276. It was found that microsatellite markers have a wide range of alleles and generally have a high informative value for identifying of genetic differences between animals and groups of animal. The number of identified alleles is one of the indicators of the genetic diversity of the population. The total number of detected alleles was 127. The Chukchi breed of deer is characterized by a high level of heterozygosity, and the random crossing system prevails over inbreeding in the population. On average, there were 7.9 alleles (Na) per locus, and the mean number of effective alleles (Ne) was 4.1. The index of fixation averaged 0.001. The polymorphism index (PIC) ranged from 0.217 to 0.946, with an average of 0.695.
