    Embedding a θ\theta-invariant code into a complete one

    Full text link
    Let A be a finite or countable alphabet and let θ\theta be a literal (anti-)automorphism onto A * (by definition, such a correspondence is determinated by a permutation of the alphabet). This paper deals with sets which are invariant under θ\theta (θ\theta-invariant for short) that is, languages L such that θ\theta (L) is a subset of L.We establish an extension of the famous defect theorem. With regards to the so-called notion of completeness, we provide a series of examples of finite complete θ\theta-invariant codes. Moreover, we establish a formula which allows to embed any non-complete θ\theta-invariant code into a complete one. As a consequence, in the family of the so-called thin θ\theta--invariant codes, maximality and completeness are two equivalent notions.Comment: arXiv admin note: text overlap with arXiv:1705.0556

    AbstractLet M be an arbitrary submonoid of the free monoid A∗, and let X⊆M be a variable length code (for short a code). X is weakly M-complete iff any word in M is a factor of some word in X∗ [J. Néraud, C. Selmi, Free monoid theory: Maximality and completeness in arbitrary submonoids, Internat. J. Algebra Comput. 13 (5) (2003) 507–516]. Given a regular submonoid M, and given an arbitrary code X⊆M, we are interested in the existence of a weakly M-complete code Xˆ that contains X. Actually, in [J. Néraud, Completing a code in a regular submonoid, in: Acts of MCU’2004, Lect. Notes Comput. Sci. 3354 (2005) 281–291; J. Néraud, Completing a code in a submonoid of finite rank, Fund. Inform. 74 (2006) 549–562], by presenting a general formula, we have established that, in any case, such a code Xˆ exists. In the present paper, we prove that any regular circular code X⊆M may be embedded into a weakly M-complete one iff the minimal automaton with behavior M has a synchronizing word. As a consequence of our result an extension of the famous theorem of Schützenberger is stated for regular circular codes in the framework of regular submonoids. We study also the behaviour of the subclass of uniformly synchronous codes in connection with these questions

    The explanation of effective factors on the healthy lifestyle of the nursing students' view: A qualitative study

    Nurses have a key role in improving the client's health and their lifestyle is effective in representing services to the patients and client. This study aims to investigate the nursing students' perception about the effective factors on their healthy lifestyle. This study was done qualitatively with the content analysis approach and through 20 semi-structured and deep interviews with undergraduate nursing students of Tehran city. The participants were selected through purposive sampling. Data were analyzed using qualitative content analysis. All interviews were recorded, transcribed, and reviewed. Also, codes were extracted. Based on centrality, codes were put in a sub-category and then by reviewing sub-categories again, they were put in categories and finally, a theme was determined. During the process of content analysis, theme on the effective factors on nursing students' healthy life style was revealed. The theme included 9 categories: ``the perception of effective factors on health promotion'', ``having enough time'', ``inner factors'', ``work-related factors or activity'', ``environmental factors'', ``knowledge and awareness'', ``individual factors'', ``social factors'', and ``perceived priorities''. The participants believed that various and widespread factors affected their health promotion level. The extension of these factors demands the complete attention to different health dimensions and how to improve it by person, family, and community.

    A note on the factorization conjecture

    Full text link
    We give partial results on the factorization conjecture on codes proposed by Schutzenberger. We consider finite maximal codes C over the alphabet A = {a, b} with C \cap a^* = a^p, for a prime number p. Let P, S in Z , with S = S_0 + S_1, supp(S_0) \subset a^* and supp(S_1) \subset a^*b supp(S_0). We prove that if (P,S) is a factorization for C then (P,S) is positive, that is P,S have coefficients 0,1, and we characterize the structure of these codes. As a consequence, we prove that if C is a finite maximal code such that each word in C has at most 4 occurrences of b's and a^p is in C, then each factorization for C is a positive factorization. We also discuss the structure of these codes. The obtained results show once again relations between (positive) factorizations and factorizations of cyclic groups

The idea is anyone can send a news item using their web based gadget which is managed by administrator to whom the editor’s panel kept in charge for this to make it visible for the masses. This portal is developed using HTML, PHP & CSS technologies and SQL Server

    Early career music teachers and trauma: A mixed methods study

    Get PDF
    Existing research rarely directly addresses individual trauma experiences of early career music teachers, despite copious research on adjacent areas such as stress and burnout. Early career music teachers have seldom had the opportunity to share stories of their trauma in the literature. Following an explanatory-sequential mixed method (Creswell, 2015), the researcher surveyed 250 music educators about their self-reported trauma experiences and then interviewed six of those participants to gain explanation of the survey data and to further illuminate their stories. Participants evaluated their own experiences using the definition of individual trauma from the Substance Abuse and Mental Health Services Administration (SAMHSA, 2014). The most common type of trauma they reported was non-life threatening emotional, and the least common was life-threatening physical. The coded interview data revealed the interconnections between various factors that influenced and were influenced by trauma. The researcher explored the topic of attrition as it applied to those who have experienced trauma in their early careers, and concluded with recommendations for continued research and advocacy regarding the trauma experiences of teachers, in addition to a call to action for leaders to strengthen mentorship structures and teacher preparation programs

    Improving Disaster Preparedness and Planning for Chronic Disease Populations

    The significant rise of both chronic diseases and disasters in the last 20 years and the healthcare outcomes of individuals with chronic diseases during and in the aftermath of disasters have raised concerns among public health practitioners, healthcare providers, the U.S government, and the general public. Researchers have indicated that during disasters, the health outcomes of individuals with chronic diseases are significantly unfavorable compared to the general public. However, there is inadequate information on the management of chronic diseases, quality of care, and resource identification and allocation by disaster responders. This qualitative, grounded theory study, explored how the study participants addressed chronic disease needs during and after disasters. A total of 15 adult disaster relief responders who had been involved in disaster planning, response, or care management of individuals with chronic diseases, were recruited through snowballing, public/bulleting postings, and social media. Using the ecological model of disaster management allowed the identification of individual and societal influences that hinder disaster preparedness and chronic disease management. Data collection consisted of semistructured in-depth open-ended interview questions, allowing participants to share their lived experiences. Data were analyzed through open, axial, and selective coding and managed using the Atlas ti8 software. The findings supported the ecological model of disaster management and strategies such as the use of special needs shelters during impending disasters. Such strategies could enhance disaster preparedness and planning efforts and potentially improve health outcomes during and after disasters

    Developing early years teachers' Dialogic Reading (DR) skills through the use of video enhanced self-reflection

    The use of video within teacher training has been shown to increase motivational and emotional engagement and support teachers to ‘notice’ relevant teaching and learning events (van Es & Sherin, 2009), which can improve pedagogical practices (Tripp & Rich, 2012b). This study introduced video enhanced self-reflection into a Dialogic Reading (DR) training programme for teachers working within early years education. DR is an evidence-based intervention that aims to enhance oral language skill of pre-school children by increasing the complexity of adult-child interactions during shared book reading. The research employed a mixed-method nested case study design. Two participating teachers, working in different schools, delivered a 6-week DR intervention to one selected pre-school pupil from their class; giving two participating teacher-child dyads. Using video clips of their own DR practice, the participating teachers engaged in three self-reflection sessions. Qualitative analysis of their contributions indicated that video supported them to engage in productive reflection and apply the theoretical underpinnings of DR to their shared reading practice. Quantitative analyses of the language used by the participating pupils within pre- and post-test DR sessions demonstrated a positive effect for the intervention. The implications for theory and practice, regarding the use of video as a training tool, are discussed
