    In this work, the production processes of heavy neutral scalar and pseudo scalar associated with standard model gauge boson ZLZ_L at future e+e−e^{+}e^{-} colliders (ILC and CLIC) are examined. The total and differential cross sections are calculated for the processes in the context of the littlest Higgs model. Also dependence of production processes to littlest Higgs model parameters in the range of compatibility with electroweak precision measurements and decays to lepton flavor violating final states are analyzed. We have found that both heavy scalar and pseudoscalar will be produced in e+e−e^+e^- colliders. Also the depending on the model parameters, the neutral heavy scalar can be reconstructed or lepton flavor violating signals can be observed.Comment: 16 pages, version in APP

    Production of relative clauses in monolingual Turkish children

    Research on the production of relative clauses (RCs) has shown that in English, although children start using intransitive RCs at an earlier age, more complex, bi-propositional object RCs appear later (Hamburger & Crain, 1982; Diessel and Tomasello, 2005), and children use resumptive pronouns both in acceptable and unacceptable ways (McKee, McDaniel, & Snedeker, 1998; McKee & McDaniel, 2001). To date, it is unclear whether or not the same picture emerges in Turkish, a language with an SOV word-order and overt case marking. Some studies suggested that subject RCs are more frequent in adults and children (Slobin, 1986) and yield a better performance than object RCs (Özcan, 1996), but others reported the opposite pattern (Ekmekçi, 1990). Our study addresses this issue in Turkish children and adults, and uses participants’ errors to account for the emerging asymmetry between subject and object RCs. 37 5-to-8 year old monolingual Turkish children and 23 adult controls participated in a novel elicitation task involving cards, each consisting of four different pictures (see Figure 1). There were two sets of cards, one for the participant and one for the researcher. The former had animals with accessories (e.g., a hat) whereas the latter had no accessories. Participants were instructed to hold their card without showing it to the researcher and describe the animals with particular accessories. This prompted the use of subject and object RCs. The researcher had to identify the animals in her card (see Figure 2). A preliminary repeated measures ANOVA with the factor Group (pre-school, primary-school children) showed no differences between the groups in the use of RCs (p>.1), who were therefore collapsed into one for further analyses. A repeated measures ANOVA with the factors Group (children, adults) and RC-Type (Subject, Object) showed that children used fewer RCs than adults (F(1,58)=7.54, p<.01), and both groups used fewer object than subject RCs (F(1,58)=22.46, p<.001), but there was no Group by RC-Type interaction (see Figure 3). A similar ANOVA on the rate of grammatical RCs showed a main effect of Group (F(1,58)=77.25, p<.001), a main effect of RC-Type (F(1,58)=66.33, p<.001), and an interaction of Group by RC-Type (F(1,58)=64.6, p<.001) (see Figure 4). Children made more errors than adults in object RCs (F(1,58)=87.01, p<.001), and children made more errors in object compared to subject RCs (F(1,36)=106.35, p<.001), but adults did not show this asymmetry. The error analysis revealed that children systematically avoided the object-relativizing morpheme –DIK, which requires possessive agreement with the genitive-marked subject. They also used resumptive pronouns and resumptive full-DPs in the extraction site similarly to English children (see Figure 5). These findings are in line with Slobin (1986) and Özcan (1996). Children’s errors suggest that they avoid morphosyntactic complexity of object RCs and try to preserve the canonical word order by inserting resumptive pronouns in the extraction site. Finally, cross-linguistic similarity in the acquisition of RCs in typologically different languages suggests a higher accessibility of subject RCs both at the structural (Keenan and Comrie, 1977) and conceptual level (Bock and Warren, 1986)

    RUNS IN FOLKTALES AND THE DYNAMICS OF TURKISH RUNS - A CASE-STUDY

    Get PDF
    Runs are inherent to Turkish folktales, as they are to folktales of certain other cultures. They are traditionally accepted forms, and useful compositional devices that function as bridges between the world of the tale and the world of everyday reality. This study attempts to demonstrate the dynamics of runs through an examination of the stylistic techniques that narrators employ, showing in particular how surface morphology and syntax help narrators to encode the traditional function and the meaning of runs. It argues that there are also extralinguistic factors contributing to the dynamics of runs, namely the common cultural background of the narrator and the audience, and suggests that runs act as cognitive signals for the audience to activate its previously acquired knowledge of the folktale world. The analysis tries to show that runs are not used merely for their compositional utility and do not restrict the narrator, but are effective means by which the narrator can manipulate the audience's outlook on the tale

    European particle physics groups interested in searching signals of new physics both with neutrinos, at T2K experiment, and at the intensity frontier, with the Belle-II experiment at the SUPERKEKB machine, want to share between them and with KEK laboratory their knowledge in data analysis and detector technologies. Such knowledge sharing will enhance skills and competences of all participants, will allow Europe to play a primary role in the search for deviations from the actually known fundamental physics in the flavour sector and, last but not least, will produce an unprecedented collaboration with japanese scientists on the ground of dissemination and outreach.MSCA-RISE - Marie Skłodowska-Curie Research and Innovation Staff Exchange (RISE) (H2020-MSCA-RISE-2014

    Young Learners' Attitudes and Motivation towards Learning English in terms of Dörnyei’s Theory of Motivation

    Get PDF
    This study tries to explore young learners' attitudes and motivation towards learning English via Dörnyei’s motivational self-system. Designed as a qualitative study, the study employs interview schedules and an observation checklist that were adopted from Dörnyei and Csizer (2006) and a questionnaire designed by Ryan (2005). The data collection tools were, then, developed by the advisor and the researcher of the study upon expert opinion. The study was carried out with 57 primary school second-grade students from a state primary school in both face-to-face and online settings. The data were analyzed by thematic content analysis and coding via the Nvivo program. According to the results of the study, a positive learning environment and activities are significant factors that have an impact on young learners' attitudes and motivation to learn English. Regardless of the teaching environment, students' attitudes were mainly positive towards learning English and they were intrinsically motivated. This is especially important in countries where English proficiency is not as high as expected. &nbsp

    Experiential Aspects of Crime: A Narrative Approach

    Get PDF
    The central goal of the current thesis is to understand the experience of crime committed by various types of offenders and, in so doing to examine its psycho-social and criminal background correlates. This is explored by drawing on a narrative approach. This approach includes both the episodic roles criminals play during the crime as well as broader aspects of their understanding of their life story. A consequent research question is the relationship between their life narratives and their conceptualisation of their roles when committing their crimes. This perspective views the immediate components of the criminal experience as emotional and cognitive, essentially subjective in nature, thus self-report measures are used to uncover these internal processes. In the current thesis, the Narrative Roles Questionnaire (NRQ) was used. This is a standardized, quantitative method designed to reveal an offender’s crime narratives. In addition to the NRQ an offender’s general view of self/world and life was measured with the Life Narrative Questionnaire which is composed of positive and negative life narrative themes. The offenders’ history of offending was measured by the D-60 (History of Offending Questionnaire) which consists of three distinct offending styles, namely Instrumental, Sensory and Power. All these measures, along with a demographic information were completed by 468 Turkish prison inmates. Each questionnaire was translated into Turkish. Reliability and validity analyses revealed more than satisfactory results, which indicated the applicability of these scales in Turkish culture. Results indicated a consistency between life and offence narratives in terms of strength. This suggests that independent of the direction (negative vs positive), offenders who have a strong attitude towards themselves/life/world have a stronger commitment to the roles they enact during the offence. There was also a significant relationship between history of offending styles and offence roles. This showed that except for the Victim role, all offence roles are associated with aspects of the history of offending. This differentiates the Victim role from others as being more circumstantial and not associated with previous criminal behaviour. These results are relevant to developing different rehabilitation strategies for offenders based on the roles they enact during the offence. In addition, the results show that, while life outside of crime has more predictive power for the Victim and Hero NRQ roles, for others history of offending behaviour has more predictive power. The results of the third relationship, between the life narrative themes and history of offending styles, show that a negative life narrative theme is associated with a history of Instrumental and Sensory offending styles. Whereas a positive life narrative is associated with the Power offending style. Also, offenders with a strong attitude towards life/world/themselves score higher on the Power offending style. These results uncover the relationship between criminal history and how offenders see themselves/life and world outside of crime. There is evidence supporting specialisation in offending because distinct factors emerged in the history of offending scale. Each offending style is shown to be associated with different psycho-social and criminal background characteristics. The results show that the effects of an offender’s attitude towards a) their lives outside of crime, b) their history of criminal behaviour, and c) their experience of crime, vary based on the narrative roles they enact during the offence. Furthermore, the results show that life narrative themes moderate the relationship between history of offending styles and offence roles, which indicates that one’s view of self/life/world (which is accepted as a dynamic, changing and unfolding factor) has an impact on how history of offending (which is a static, unchanging factor) affects the offence role choice which is an immediate experiential aspect of crime. The major methodological contribution is the adaptation of the three primary measures to the Turkish context and the work shows the high ecological validity of these scales in a novel cultural context. Along with presenting an understanding of the experiential aspects of criminality, the major theoretical contribution of the current thesis is to provide empirical evidence for the theory that there is consistency in an offender’s behaviours in crime and outside of crime, and that this consistency is effectively revealed through the application of narrative theory. The theory and results open paths to the development of rehabilitation and crime prevention strategies by targeting life narratives of offenders. They point to the potential development of interview techniques based on offence roles. Furthermore, there are applications of the history of offending and offence role relationships to police investigations; understanding the revealed associations would help investigators to infer offender characteristics

    The role of psychopathy factors in reactive aggression within a sample of prisoners

    Get PDF
    Purpose – The purpose of this paper is to examine the role of four psychopathy factors (Interpersonal Manipulation (IPM), Callous Affect (CA), Erratic Lifestyle (ELS), and Antisocial Behaviour (ASB)) and the length of incarceration in reactive aggression. The predictive effect of dissatisfaction with peer relations, childhood experiences of violence, and criminal friends on reactive forms of aggressive acts is also explored. Design/methodology/approach – In total, 129 (n=129) male prisoners incarcerated in Stargard Szczecinski Prison were recruited for the study. Cross-sectional design using self-report questionnaire of retrospective and prospective nature was utilised. Findings – Hierarchical multiple regression analysis revealed that only one psychopathy facet, IPM, forms a significant association with reactive aggression. Another accurate correlate of reactive aggression was the length of incarceration. Originality/value – The results of the present study indicate that the commonly suggested two-factor models of psychopathy may be misguided. Future studies examining the effect of psychopathy facets on aggression should consider IPM and CA as separate dimensions. Additionally, this study is the first to demonstrate that reactive aggression may be exacerbated during incarceration
