Wortgruppenlexeme zwischen Wortbildung und Phraseologie
Authors: Elsen Hilke
Published: January 2018

This paper presents a group of phraseological units which are similar to compounds in respect to structure, semantics and cognitive aspects. Terms such as Kap der guten Hoffnung (‘Cape of Good Hope’), Dreißigjähriger Krieg (‘Thirty Years’ War’), rechter Winkel (‘right angle’) and erste Hilfe (‘first aid’) are often considered to be problematic. These so-called Wortgruppenlexeme (WGL, multiword lexemes, phrasal lexical units) can be seen as lexemes consisting of two or more orthographically separate words. They form a syntactic and semantic unit, are motivated, and more or less free of connotations. They are relatively fixed, except for inflection. Many of them are phrasal names or clearly defined terms. Like compounds they are bases of shortening. In some variants of German they are extremely frequent and productive. Analyses of data collections show a relatively high percentage of WGL in languages for special purposes. They constitute 20% or even more than a third of the lexicon, considering repertory as well as neologisms. Thus, WGL are a systematic and productive way to coin new words analogously to compounds, but in contrast to all other types of phraseological units. To summarize, there are several reasons to posit WGL next to compounding and to see them as lexemes. Accordingly, they should be considered as analytical word formations. In this article we plead for the treatment of WGL in German word formation.

Brock, F, Christopher, J, Harry, B, and Carl, WT. Manipulating field dimensions during small-sided games impacts the technical and physical profiles of Australian footballers. J Strength Cond Res 32(7): 2039–2044, 2018—This study investigated the effect of manipulating field dimensions on the technical and physical profiles of Australian football (AF) players during small-sided games (SSGs). A total of 40 male players (23.9 ± 3.5 years) participated in 3, five-a-side SSGs; defined as “small” (20 × 30 m; 600 m2), “medium” (30 × 40 m; 1,200 m2), and “large” (40 × 50 m; 2,000 m2). Notational analyses enabled the quantification of technical skill indicators, whereas physical activity profiles were measured using microtechnology, resulting in 18 criterion variables. A multivariate analysis of variance modeled the main effect of field dimension on the criterion variables. A significant main effect was observed (V = 1.032; F
38, 102 = 2.863; p ≤ 0.05), with the “small” and “medium” SSGs generating more turnovers and ineffective handballs relative to the “large” SSG. Furthermore, the “small” SSG generated more tackles and fewer bounces compared with the “large” SSG. The “large” SSG generated a greater absolute distance, relative distance, maximum velocity, PlayerLoad, and distance >4.16 m·s−1 compared with the “small” and “medium” SSGs. These results provide AF coaches with insights into how task constraint manipulation impacts the technical and physical profiles of players during small-sided game-play. Thus, coaches and physical performance specialists could use this information to assist with the tactical periodization of technical complexity and physical load at different phases of the AF season.
Ventral and Dorsal Pathways Relate Differently to Visual Awareness of Body Postures under Continuous Flash Suppression
Authors: Zhan Minye , Goebel Rainer , de Gelder Beatrice
Published: January 2018

Visual perception includes ventral and dorsal stream processes. However, it is still unclear whether the former is predominantly related to conscious and the latter to nonconscious visual perception as argued in the literature. In this study upright and inverted body postures were rendered either visible or invisible under continuous flash suppression (CFS), while brain activity of human participants was measured with functional MRI (fMRI). Activity in the ventral body-sensitive areas was higher during visible conditions. In comparison, activity in the posterior part of the bilateral intraparietal sulcus (IPS) showed a significant interaction of stimulus orientation and visibility. Our results provide evidence that dorsal stream areas are less associated with visual awareness.
Opposing and Complementary Topographic Connectivity Gradients Revealed by Quantitative Analysis of Canonical and Noncanonical Hippocampal CA1 Inputs
Authors: Sun Yanjun , Nitz Douglas A. , Holmes Todd C. , Xu Xiangmin
Published: January 2018

Physiological studies suggest spatial representation gradients along the CA1 proximodistal axis. To determine the underlying anatomical basis, we quantitatively mapped canonical and noncanonical inputs to excitatory neurons in dorsal hippocampal CA1 along the proximal-distal axis in mice of both sexes using monosynaptic rabies tracing. Our quantitative analyses show comparable strength of subiculum complex and entorhinal cortex (EC) inputs to CA1, significant inputs from presubiculum and parasubiculum to CA1, and a threefold stronger input to proximal versus distal CA1 from CA3. Noncanonical subicular complex inputs exhibit opposing topographic connectivity gradients whereby the subiculum-CA1 input strength systematically increases but the presubiculum-CA1 input strength decreases along the proximal-distal axis. The subiculum input strength cotracks that of the lateral EC, known to be less spatially selective than the medial EC. The functional significance of this organization is verified physiologically for subiculum-to-CA1 inputs. These results reveal a novel anatomical framework by which to determine the circuit bases for CA1 representations.
Mitochondrial Ultrastructure Is Coupled to Synaptic Performance at Axonal Release Sites
Authors: Cserép Csaba , Pósfai Balázs , Schwarcz Anett Dóra , Dénes Ádám
Published: January 2018

Mitochondrial function in neurons is tightly linked with metabolic and signaling mechanisms that ultimately determine neuronal performance. The subcellular distribution of these organelles is dynamically regulated as they are directed to axonal release sites on demand, but whether mitochondrial internal ultrastructure and molecular properties would reflect the actual performance requirements in a synapse-specific manner, remains to be established. Here, we examined performance-determining ultrastructural features of presynaptic mitochondria in GABAergic and glutamatergic axons of mice and human. Using electron-tomography and super-resolution microscopy we found, that these features were coupled to synaptic strength: mitochondria in boutons with high synaptic activity exhibited an ultrastructure optimized for high rate metabolism and contained higher levels of the respiratory chain protein cytochrome-c (CytC) than mitochondria in boutons with lower activity. The strong, cell type-independent correlation between mitochondrial ultrastructure, molecular fingerprints and synaptic performance suggests that changes in synaptic activity could trigger ultrastructural plasticity of presynaptic mitochondria, likely to adjust their performance to the actual metabolic demand.
Seasonal variation in aragonite saturation in surface waters of Puget Sound – a pilot study
Authors: Pelletier Gregory , Roberts Mindy , Keyzers Mya , Alin Simone R.
Published: January 2018

A pilot study of sampling, using monthly marine flights over spatially distributed stations, was conducted with the aim to characterize the carbonate system in Puget Sound over a full year-long period. Surface waters of Puget Sound were found to be under-saturated with respect to aragonite during October–March, and super-saturated during April–September. Highest pCO2 and lowest pH occurred during the corrosive October–March period. Lowest pCO2 and highest pH occurred during the super-saturated April–September period. The monthly variations in pCO2, pH, and aragonite saturation state closely followed the variations in monthly average chlorophyll a. Super-saturated conditions during April–September are likely strongly influenced by photosynthetic uptake of CO2 during the phytoplankton growing season. The relationship between phytoplankton production, the carbonate system, and aragonite saturation state suggests that long-term trends in eutrophication processes may contribute to trends in ocean acidification in Puget Sound.
A Home Visiting Parenting Program and Child Obesity: A Randomized Trial
Authors: Ordway Monica Roosa , Sadler Lois S. , Holland Margaret L. , Slade Arietta , Close Nancy , Mayes Linda C.
Published: January 2018

BACKGROUND:

Young children living in historically marginalized families are at risk for becoming adolescents with obesity and subsequently adults with increased obesity-related morbidities. These risks are particularly acute for Hispanic children. We hypothesized that the prevention-focused, socioecological approach of the “Minding the Baby” (MTB) home visiting program might decrease the rate of childhood overweight and obesity early in life.

METHODS:

This study is a prospective longitudinal cohort study in which we include data collected during 2 phases of the MTB randomized controlled trial. First-time, young mothers who lived in medically underserved communities were invited to participate in the MTB program. Data were collected on demographics, maternal mental health, and anthropometrics of 158 children from birth to 2 years.

RESULTS:

More children in the intervention group had a healthy BMI at 2 years. The rate of obesity was significantly higher (P < .01) in the control group (19.7%) compared with the intervention group (3.3%) at this age. Among Hispanic families, children in the MTB intervention were less likely to have overweight or obesity (odds ratio = 0.32; 95% confidence interval: 0.13–0.78).

CONCLUSIONS:

Using the MTB program, we significantly lowered the rate of obesity among 2-year-old children living in low-socioeconomic-status communities. In addition, children of Hispanic mothers were less likely to have overweight or obesity at 2 years. Given the high and disproportionate national prevalence of Hispanic young children with overweight and obesity and the increased costs of obesity-related morbidities, these findings have important clinical, research, and policy implications.
Direito e institucionalismo econômico: apontamentos sobre uma fértil agenda de pesquisa
Authors: Coutinho Diogo R.
Published: January 2018

RESUMO O artigo explora a dimensão jurídica nos trabalhos de autores pertencentes a diferentes correntes institucionalistas. Argumenta que análises centradas nas instituições - em especial uma delas, a chamada economia política institucionalista - oferecem ao direito e aos juristas engajados na teoria e na prática do direito econômico a oportunidade de tomar parte em um rico diálogo sobre do desenvolvimento econômico e seus enigmas. Isso resulta do fato de o institucionalismo ser um campo eminentemente interdisciplinar e transversal, no qual as agendas de pesquisa das ciências sociais podem almejar ganhos explicativos conjuntos e fertilizações cruzadas entre as disciplinas.
Understanding and overcoming the “positive profits with negative surplus-value” paradox
Authors: LUCAS GUSTAVO DAOU , SERRANO FRANKLIN
Published: January 2018

ABSTRACT This paper explains the “positive profits with negative surplus-value” example of Steedman (1975) and shows that while in joint production systems individual labour values can be negative, the claim that the total labour embodied in the surplus product of the economy (surplus-value) can also be negative is based on assumptions that have no economic meaning (such as negative activity levels).The paper also provides a way to measure the surplus-value of joint production systems which overcomes the problems of the traditional concept and restates the proposition that a positive amount of surplus labour is a necessary condition for positive profits.
Empiricism in Herbert Simon: Administrative Behavior within the evolution of the Models of Bounded and Procedural Rationality
Authors: HORTAL ALEJANDRO
Published: January 2018

ABSTRACT This paper contextualizes Simon’s book, Administrative Behavior, within the evolution of his ideas arguing, contrary to what some have posited, that the common element that unites this book with the rest of Simon’s work is not the criticism of the classical approach, but an epistemological frame, based on an empirical methodology. This empiricism is the element that remained constant during his career and led him to introduce psychological factors when explaining the behavior of economic agents under his models of bounded and procedural rationality.
The political economy of reforms and the present Chinese transition
Authors: JABBOUR ELIAS , DANTAS ALEXIS
Published: January 2018

ABSTRACT The main aim of this paper is to demonstrate, through a review of China’s economic reforms, that the emergence of a large private sector and the increased sophistication and diversification of industry has required the continual reorganization of activities between the state and private sectors of the economy. We argue in this paper that the state began to play a major role in important industries and in big finance, as well as in the coordination and socialization of investment, such as economic policy (monetary and fiscal), foreign trade and, especially, the launch of new and higher forms of economic planning.

Published: January 2018

The electronic structure and absorption spectra of cyanine dyes – tetrazoloisoindole derivatives and triazoloisoindole were calculated. It was shown that these dyes, in terms of their electronic structure, are trimethine cyanine, although formally they are monomethine cyanine. The electron donation of the tetrazoloisoindole and triazoloisoindole residues was determined on the Ilchenko scale, which allows them to quantitatively quantify their Bruker basicity in comparison with the most known heterocyclic end groups of cyanine dyes.
Investigating wordʼs semantic component with qualitative analysis
Authors: Grigoriev A.A. , Ushakova T.N.
Published: January 2018

Present study investigates word’s semantic component with qualitative analysis. Materials of the dictionary of associative reactions of schoolchildren 7—18 years old were used as data for analysis (Goldin et al., 2011). Associative circles of ten words-stimuli were analyzed, five with positive connotations and five with a negative one. Associate circle of each word-stimulus had different dimensions of semantic components of a word: knowledge about the world, abiyt the language and affective connotations of the word. Using the frequency of usage of these semantic elements of the word we analyzed statistic significance of differences between positivity and negativity and between different age groups. Several statistically significant differences were found. Positive stimuli more often caused the reaction of refusal, and less often — synonymous reaction. The percentage of refusal, the frequency of associations, which are grammatical modifications of words-stimuli and frequency of “consonant” associations, both diminish with age; the frequency of synonymous associations increases. The developmental dynamics of these four indexes was described for each word-stimulus

The paper presents an original questionnaire measuring abilities of social problem-solving, based on a theory of social problem-solving of D’Zurilla. Aprobation of the questionnaire, its psychometric qualities were investigated on a sample of 329 individuals (95 males, 234 females). The factors were investigated and construct validity was tested on an additional sample of 466 individuals (80 males, 385 females). Structural equations were used to test the factor structure of the 38-items questionnaire. To test construct validity, we used COPE-questionnaire and the Diener’s Scale of life satisfaction. The results fit the hypothesis about the correlation with p<0,001. The presented diagnostic measure is valid and can be used in research.

Authors: Sozinova I.M. , Bakhchina A.V. , Alexandrov Y.I.
Published: January 2018

The goal of the present research was to investigate psychophysiological bases of moral dilemmas solving by children. We assessed the heart rhythm of Russian children aged 4—11 (N=75) during interview, solving moral dilemmas, and subsequent questionnaires. We compared data of two age group: 4—7 years old and 8—11 years old. The task of moral dilemma was to choose who would take a resource: an in-group member (resource is needed for an optional benefit) or an out-group member (resource is needed for survival). questionnaires. There was a significant decrease of heart rate moral decisions in younger children (4—7 years old). There was no differences of heart rate moral decisions in elder children (8—11 years old). We speculate that younger children have no mismatch during decision making due to scarcity of their new experience. They do not have to activate the adaptation processes during moral dilemmas solving. The results are discussed from the position of the system evolutionary approach and the notions of changes in heart rate variability as an indicator of adaptation processes.

Published: January 2018

This paper presents results of our analysis on gender and age differences in the effect of childhood stressful events on severity of anxiety and depression symptoms, coping behaviors and inherent personality traits in patients with affective disorders. The study included 440 patients hospitalized in our neuropsychiatric clinic. The results showed that in women childhood stressful events are associated with severity of anxiety and depression symptoms, as well as with some coping strategies and inherent personality traits, with some variability in different age groups. In men, a significant association with childhood stressful events was observed only with severity of depression and with scores for neuroticism. The associations in men also varied between different age groups.

DEVELOPMENT OF DISTRIBUTED INTELLIGENT SYSTEMS ON BASE OF ONTOLOGICAL ANALYSIS AND SEMANTIC WIKI TECHNOLOGIES
Authors:   Institute of Software Systems of the National Academy of Sciences of Ukraine, Rogushina J.
Published: January 2018

The necessity of automated knowledge acquisition by intelligent information systems from the distributed Web environment is considered. The feasibility of using ontological analysis to represent such knowledge is assessed. The necessity of replenishment of this knowledge from more dynamic information resources that provide automated processing of information (such as semantic Wiki resources) is grounded. Such information processing requires the development of formal model and methods for mapping of Wiki elements to ontology elements. The expressive possibilities of the Semantic MediaWiki technological environment that can be used for semantic marking of natural language and multimedia information are analyzed. The method of semantic markup of Wiki-resources by elements of the ontological model of the domain is proposed. This markup is based on the establishment of correspondences between the elements of the formal model of such ontology (classes, individuals, object and data properties) and the elements of the Semantic MediaWiki (categories, semantic properties, references). Method for improving the domain ontology is developed on the basis of a Wiki resource semantically marked by elements of this ontology. Approbation of the developed models and methods is resulted on example of development of the electronic version of the Great Ukrainian Encyclopedia on the Semantic MediaWiki platform. The novelty of the work lies in the way of comparing the elements of the ontological model of the domain with the elements of the semantic Wiki-resource, and also in the method of improving the ontology of the domain that is used for semantic markup of the Wiki resource, based on the changes and additions that are made to this resource.
PROBABILISTIC FORMAL CONCEPTS IN SOME CLASSIFICATION TASKS
Authors:   Sobolev institute of mathematics, SB RAS, Vityaev E. , Martynovich V. ,   Sobolev institute of mathematics, SB RAS
Published: January 2018

The definition of formal concepts as fixed points of implication is considered. On the basis of this definition, the notion of probability formal concepts is introduced by replacing implications with special, maximally specific probability rules for which it was previously proved that fixed points for them are logically consistent. The ProbClosure algorithm for detecting probabilistic formal concepts is defined. To develop algorithms for clustering and classification, the context is considered as a sample from the general population. Generalizing the algorithm ProbClosure, algorithms for clustering ConcClosure and StatClosure are defined by introducing various energy functionals that determine the degree of noncontradiction of the rules at a fixed point. Classification algorithms are obtained by applying clustering algorithms to new data. Classification algorithms obtained are compared with the decision trees C4.5, ID3 and the classification method based on the lattice of formal concepts. The comparison was made on the data of the UCI repository. The obtained results showed comparatively high accuracy of the developed algorithms in comparison with these methods.
Microwave energy-based synthesis and characterisation of hollow carbon nanospheres decorated with carbon nanotubes or metal oxide nanowires
Authors: Poyraz Selcuk
Published: January 2018

Hollow carbon nanospheres (HCNSs), with either carbon nanotube (CNT) or metal oxide nanowire (MONW) decoration on their surface, were synthesised as building materials with a great potential for the next generation advanced applications. A well-established, polymeric latex NS synthesis method and a simply modified version of a microwave (MW) energy-based carbonisation approach, i.e. Poptube, were systematically combined to obtain these HCNSs. Through this simple, facile, affordable and easily scalable ‘combined synthesis method’, it was managed to successfully produce HCNSs with an unique morphological, spectroscopic, thermal and elemental features, all of which were strongly supported by both various material characterisation test results and the relevant previous literature data. Thus, it is believed that the as-synthesised CNT or MONW decorated HCNSs (CNT–MONW/HCNS) from the above-mentioned method would soon become the materials of preference for the next generation advanced applications in various science and engineering fields. Keywords: Hollow carbon nanospheres, carbon nanotubes, metal oxide nanowires, microwave energy, conducting polymer.
Formation mechanism of Pd/PVP nanoparticles: effect of ultrasonic irradiation time
Authors: Nemamcha Abderrafik
Published: January 2018

The effects of ultrasonic irradiation time on the palladium nanoparticles (Pdns) formation mechanism have been investigated using UV-Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). Pdns colloids have been prepared by ultrasonic irradiation of Pd(NO3)2 solutions at different irradiation times (from 30 to 180 minutes). The obtained results show that the rate of sonochemical reduction of Pd(II) ions has been found to be dependent upon the irradiation time. The kinetic of Pdns formation can also be correlated with the rate of sonochemical reduction ofPd(II) ions, as well as with the role of PVP molecules. The results suggest a three-step mechanism to describe the Pdns formation as a function of ultrasound irradiation time. During the first step, the Pd(II) ions are rapidly reduced to Pd(0) atoms, and when the concentration of Pd(0) atoms is sufficient for nucleation, the formation of primary particles occurs which are stabilised by a maximal number of PVP molecules. During the second step, these particles grow progressively by adsorption of the Pd(0) atoms and the obtained particles are coordinated to all available PVP molecules. The third step corresponds to decrease of the bounded PVP to the particle surface and the growth of the large particles at the expense of the unstable small ones. Keywords: Palladium nanoparticles, ultrasound irradiation, formation mechanism, UV-visible spectroscopy, FT-IR spectroscopy, TEM.
Activity concentrations in bottled drinking water in Saudi Arabia and consequent dose estimates
Authors: Al-Ghamdi A. H.
Published: January 2018

The natural radioactivity concentrations of 226Ra, 232Th and 40K were determined in different brands of bottled drinking water samples collected from the local market of Saudi Arabia. The average measured activity concentrations of the nuclides were found to be 0.77, 1.3 and 11.1 Bq l-1, respectively. The total average annual effective doses due to all three natural radionuclides on different age groups of infants, children and adults were estimated. The measured activity concentrations were compared with similar studies and the activity concentrations of natural radionuclides in bottled drinking water were found to be lower than most of these values. Also, the effective doses resulting from the consumption of bottled drinking water estimated for the three age groups were found to be below the WHO recommended limit of 0.1 mSv y-1. The results can serve as baseline levels of activity concentration in drinking water in Saudi Arabia. Keywords: Natural radioactivity, effective dose.
Silorane versus methacrylate composites: A comparative study of the micro-leakage
Authors: Fejjeri-Mezghanni Meriem
Published: January 2018

This in vitro study aimed to evaluate the micro-leakage at the occlusal and cervical margins in class II cavities in permanent molars restored with a low shrink silorane resin composite (Filtek P90) applied with or without etching and two methacrylate-based composite resins (valux plus and Amelogen® plus). Two standardised class II box cavities were prepared in proximal surfaces of 60 sound non-fluorotic permanent molars which were divided into three groups of 20 each according to the type of composite. Group I: silorane-based composite (Filtek P90) in the mesial cavity and methacrylate-based microhybrid composite (Adper single bond 2/valux plus) in the distal cavity, Group II: silorane-based composite in the mesial cavity and silorane-based composite with previous etching in the distal cavity, and Group III: silorane-based composite in the mesial cavity and methacrylate-based micro-hybrid composite (PQ1 /Amelogen plus) in the distal cavity. The samples underwent an artificial aging with thermocycling. Root apices were sealed with transparent orthodontic resin and coated with transparent varnish except 1 mm around the restoration. The specimens were immersed in 1% methylene blue solution at room temperature for 48 hour. The samples were sectioned longitudinally in the mesiodistal direction and evaluated under a stereomicroscope at 20X. Scoring was done according to the depth of methylene blue penetration into the cavities. Statistical analysis of the data was performed using SPSS 17.0 software. Silorane-based composite resin showed less micro-leakage than the methacrylate-based composites. Etching improved the sealing ability of silorane restorations. Silorane-based composite preceded by etching had less micro-leakage among the other materials used in this in vitro study. Keywords: Silorane, methacrylate based composite, sealing, micro-leakage, class II cavity
On the size-dependent vibration of the embedded double-walled carbon nanotube conveying fluid using shell model
Authors: Beni Yaghoub Tadi
Published: January 2018

In this paper, the vibration and instability of double-walled carbon nanotube (DWCNT) conveying fluid were investigated by using the modified strain gradient theory. The Donnell's shell theory was used by taking into consideration the three size effects and simply-supported boundary conditions. The effect of van der Waals force between the two intended walls and the surroundings of the DWCNT was modelled as visco-Pasternak foundation. The governing equations of the problem and boundary conditions were derived from Hamilton’s principle. Also, Navier procedure was used to solve the vibration problem. To verify the results, a comparison was drawn between the results of this study and those of the references. According to the findings, the effects of fluid velocity, stiffness and damping of visco-Pasternak foundation, length of DWCNT and size effect are more considerable in the modified strain gradient theory than in the modified couple stress theory and classical theory. Keywords: Modified strain gradient theory, Donnell’s shell theory, DWCNT, size effect, shell vibration.

Managing workplace diversity: Ethical reasoning in a socio-cultural context
Authors: Apsalone Madara
Published: January 2018

Workplaces are becoming increasingly diverse, and businesses constantly face the challenge of ensuring work ethics to strengthen competitiveness. Workplace ethics is affected not just by potential gains and losses of unethical action but also by employee morale, values and self-concept. The ethical reasoning process depends on both perception of what is ethical and the ability to justify unethical action in a given situation. In this study, we explore the role of individual, organisational and situational factors influencing the perceived degree of unethical behaviour at work. Individual socio-cultural factors include personal values, such as honesty, and socio-demographic factors, such as age, gender, education and tenure. Organisational factors are assessed through espoused values of honesty and responsibility. Finally, three situational factors are randomly introduced â€“ low wage, boredom and perceived injustice. Two hundred and eight retail employees were surveyed to assess their personal values and the perceived degree of unethical behaviour at work. We found that honesty as a personal value changes ethical reasoning, especially when situational factors, such as low wage are introduced. Moreover, older employees tend to report more ethical behaviour in the workforce. We also concluded that declaring honesty and responsibility as organisational values could have a minor positive impact on ethical behaviour mitigating the impact of the introduced situational factors. Keywords: Socio-cultural factors, values, workplace diversity, business ethics, ethical reasoning

Ergo-Scheduling
Authors: Åženyiğit Ercan
Published: January 2018

In this paper we consider scheduling problem under ergonomic risk factors. We recruit OCRA index to control musculoskeletal disorder along schedule. Modern manufacturing systems competition power depends on cost, time and flexibility level. Despite of high level automation in manufacturing system, flexibility depends on human workforce. From this perspective, for gaining high rate production, workforces have to endure high frequency manual job. This case causes musculoskeletal disorder. Musculoskeletal disorder which had to be control is one of the most important ergonomic risks in work environment. We used OCRA index mean value for ergonomic risk assessment. We also named this new type of scheduling as Ergo-Scheduling. Keywords: Ergonomic risk assessment, scheduling, single machine scheduling, deterioration, OCRA Index;

Pre-service teacherâ€™s understanding levels of capacitors and instructorsâ€™ predictions about the given responses
Authors: Yildiz Ali
Published: January 2018

This study explores the understanding levels of pre-service teachers of the elementary school mathematics teacher education undergraduate program about capacitors that they learned in the compulsory Physics-2 course in the second year of the second term, and instructorsâ€™ predictions about the teachersâ€™ responses. A total of 54 pre-service teachers participated in the study. The findings of the study reveal that 62.9% of the pre-service teachers did not know the function of a capacitor, 46.3% could not write any equations in connection with the capacitor and 57.4% could not explain any of the quantities in the formulas related to the capacitor. Instructors who taught Physics-2 at the undergraduate level were asked to predict the percentage rate of success of the answers the pre-service teachers gave about capacitors. The data reveal that the instructors were not sufficiently aware of pre-service teachersâ€™ knowledge of capacitors, although they taught them Physics-2 and evaluated them. Keywords: Capacitors, pre-service teachers, instructors, views, predictions.
