Trisomy 21 is chromosomal abnormality that occurs as a result of triplication of human chromosome 21 (Hsa21), a condition also known as Down syndrome (DS). Beside the intellectual disability and systems anomalies, motor dysfunction due to hypotonia has also been characterised in individuals with DS and yet, its aetiology remains unclear. Ts1Cje, a mouse model for DS, has a partial trisomy (Mmu16) homology to Hsa21, is widely used for DS research. This study investigated the morphological changes and degree of myelination in sciatic nerves of the Ts1Cje mice using both light and transmission electron microscopes processed images. The result showed no morphological difference in the sciatic nerve between the Ts1Cje and WT mice. The g ratio of the Ts1Cje mice was significantly (P<0.0001) higher compared to that of the WT mice. Two factors are known to determine the g ratio, the axonal diameter and the myeline thickness. There was no significant (P=0.2146) difference in the axonal diameter between the two genotypes. Interestingly, the myeline thickness was significantly (P<0.0001) thinner in nerve fibres of the Ts1Cje mice as compared to that of the WT mice. It is therefore concluded that, the hypomyelination in Ts1Cje mice may affect the conduction velocity which in turn affect their motor activity.

Published: October 2018

With social media transforming how customers interact with brands, this study explores the consumer –brand relationship in UK energy sector which has a reputation for lack of trust by customers. Using user-generated contents on Facebook pages of the ‘big six’ UK energy companies, the study qualitatively operationalised and applied three consumer-brand relationships construct, exploring the interplay between the brands and the consumer. Findings revealed various indications of brand trust, satisfaction and affiliation but overall customers are not satisfied with their relationship with energy companies, they want to know there is a brand on their side, who takes an interest in their complaints and is willing to help them out. There were forms of engagement and a sense of attachment through brand icons and winning prizes through competition. The consumers found social media a more accessible, cheaper, faster means of communicating, they often offer compliments, complain or requests for assistance. The study extends understanding of energy brands and consumer relationships and advances knowledge on the emerging research approach of thematic analysis; by extracting and analysing consumer comments on social media.

Berbeda dengan Fast Food yang merupakan makanan yang pengolahannya cepat dan siap saji, namun masih memiliki nilai nutrisi yang mencukupi. Junk Food selain penyajiannya cepat, makanan ini hanya memiliki kandungan karbohidrat dan lemak. Selama ini ada salah pengertian soal Fast Food. Ternyata tidak semua Fast Food buruk bagi tubuh kita. Hasil survei nasional yang dilakukan di ibukota seluruh provinsi di Indonesia menunjukkan bahwa pada kelompok umur 18 tahun ke atas, mengalami overweight sebesar 8,1% pada laki-laki dan 10,5% pada perempuan sedang yang menderita obes pada laki-laki 6,8% dan perempuan 13,5%. Menurut Depkes tahun 2001, melaporkan bahwa pada kelompok umur 40-49 tahun yang mengalami overweight dan obesitas pada laki-laki berturut-turut adalah 24,4% dan 23% sedang pada perempuan berturut-turut sebesar 30,4% dan 43,0%. Semakin tahun nilai prevelensi obesitas di Indoensia semakin meningkat (Sihombing M 2010). (RAP)

Head motion causes artifacts in functional magnetic resonance imaging (fMRI) scans, a problem especially relevant for task-free resting state paradigms and for developmental, aging, and clinical populations. In a cohort spanning 7-28 years old (mean age 15) we produced customized head-anatomy-specific Styrofoam molds for each subject that inserted into an MRI head coil. We scanned these subjects under two conditions: using our standard procedure of packing the head coil with foam padding about the head to reduce head motion, and using the customized molds to reduce head motion. Here we report the effects found in our first 13 subjects. In 12 of 13 subjects, the molds reduced head motion throughout the scan, and reduced the fraction of a scan with substantial motion (i.e., volumes with motion notably above baseline levels of motion). Motion was reduced in all 6 head position estimates, especially in rotational, left-right, and superior-inferior directions. Motion was reduced throughout the full age range studied, including children, adolescents, and young adults. In terms of the fMRI data itself, quality indices improved with the head mold on, scrubbing analyses detected less distance-dependent artifact in scans with the head mold on, and distant-dependent artifact was less evident in the scans with the molds on, both for the entire scan and also during only low-motion volumes. Subjects found the molds comfortable. Head molds are thus effective tools for reducing head motion, and motion artifacts, during fMRI scans.

Numerical Modelling of Structural Behaviour of Continuously Reinforced Concrete Pavement
Authors: Lai Tin
Published: October 2018

Continuously reinforced concrete pavement (CRCP) rapidly becomes a common standard in most highway pavement design due to its high performance. Early-age cracks play a crucial role in characterising CRCP's long-term performance, hence crack formations and patterns are of interest in most highway departments. The design parameters of a CRCP are studied in this work as a parametric study on efficient design configuration. Numerical experiments were performed to produce a stress profile induced by crack initiation and long-term traffic load. This work contributes a probabilistic study on crack pattern formation from typical stress profile, including environmental and shrinkage stress, as an insight into predicting the likelihood of crack patterns initiation and propagation along the depth of the concrete slab. Studies also showed transverse steel bar plays a crucial role in determining the location of the crack formation, but a minimal effect in controlling crack width and deflection. A study on the probabilistic model helps pavement design to produce a desirable crack pattern, to perform controlled-cracks that enhance the vertical load transferability of a cracked CRCP.

A Role Of Analysis Core Value, Character And Entrepreneur Leadership Towards To Successful Entrepreneur
Authors: Zulvia Yolandafitri , Adrian Arif
Published: October 2018

Leadership is one of the important factors in the successful of entrepreneurs in digital era at this time. We can find many successful business leaders, but still a lot of entrepreneur becomes go down because they dont prepare they self from an early age to knowing their core value and their character, thats problems impact to reduce their capacity to become a success entrepreneur. The success of a business leader can not be separated from the character and the core value that have. Based on the perspective of social cognitive approach, it explains how a business leader can be successful. Through this approach can be explain that the relationship between entreprenuer, personality characteristic, values and other dimensions will help whether the entreprenuer will be success or not. This paper try to find the relationship between character and value to the successful entreprenuers. It contributes to the business world, namely entrepreuner to prepare a leader starts from an early ages to be a successful entreprenuer. Based on this literature, entreprenuers can evaluate the character and core values, because from the theory there is an impact on the successful entreprenuer. It needs a further research to examine the connection in empirical study.
Hedging in Refusal Speech Act

Published: October 2018

Abstract—The refusal speech act is quite risky to lose the face of the addressee. As far as observation of the author, refusal speech act has been frequently studied, but hedging in refusal speech act has not been thoroughly studied. Thus, this article was wr itten to explain hedging in the refusal speech act. The source of the data was the Indonesian language spoken by native Indonesians. Data were collected by observational techniques and interviews towards native Indonesians in Indonesia. Data were analyzed qualitati vely based on the speech act theory and politeness. The results of this study were, first, there are three main forms of hedging in the refusal speech act in the Indonesian language; second, a hedge is used to shape the politeness in a speech act; third, i n general, the speakers used more than one hedge in a speech act; fourth, the use of form and quantity of hegdes in a speech act affects the level of politeness of speech acts; fi fth, the use of the form and the quantity of hedges were adjusted to the level of face threatening acts.
Tightening the OODA Loop: Police Militarization, Race, and Algorithmic Surveillance
Authors: Vagle Jeffrey
Published: October 2018

This Article examines how military automated surveillance and intelligence systems and techniques, when used by civilian police departments to enhance predictive policing programs, have reinforced racial bias in policing. I will focus on two facets of this problem. First, I investigate the role played by advanced military technologies and methods within civilian police departments. These approaches have enabled a new focus on deterrence and crime prevention by creating a system of structural surveillance where decision support relies increasingly upon algorithms and automated data analysis tools and automates de facto penalization and containment based on race. Second, I will explore these militarized systems, and their effects, from an outside-in perspective, paying particular attention to the racial, societal, economic, and geographic factors that play into the public perception of these new policing regimes. I will conclude by proposing potential solutions to this problem that incorporate tests for racial bias to create an alternative system that follows a true community policing model.
Open Science challenges, benefits and tips in early career and beyond
Authors: Allen Christopher P G , Mehler David Marc Anton
Published: October 2018

The movement towards open science is an unavoidable consequence of seemingly pervasive failures to replicate previous research. This transition comes with great benefits but also significant challenges that are likely to afflict those who carry out the research, usually Early Career Researchers (ECRs). Here, we describe key benefits including reputational gains, increased chances of publication and a broader increase in the reliability of research. These are balanced by challenges that we have encountered, and which involve increased costs in terms of flexibility, time and issues with the current incentive structure, all of which seem to affect ECRs acutely. Although there are major obstacles to the early adoption of open science, overall open science practices should benefit both the ECR and improve the quality and plausibility of research. We review three benefits, three challenges and provide suggestions from the perspective of ECRs for moving towards open science practices.
Experimental deception: Science, performance, and reproducibility
Authors: Galang Adrianne John R. , Genuino Daphne T.
Published: October 2018

Experimental deception has not been seriously examined in terms of its impact on reproducible science. We argue that this can either introduce methodological inconsistency leading to studies not replicating, or systematic errors that produce results peculiar to a specific lab.. This is possibly due to missing information about the context and performance of agents in the studies in which the original effects were generated, leading to either compromised internal validity, or an incomplete specification and control of variables in replication studies. Of special interest are the mechanisms by which deceptions are implemented and how these present challenges for the efficient transmission of critical information from experimenter to participant. We rehearse possible frameworks that might form the basis of a future research program on experimental deception and make some recommendations as to how such a program might be initiated.
Further Development of the Children's Mathematics Anxiety Scale UK
Authors: Petronzi Dominic
Published: October 2018

There are currently many mathematics anxiety rating scales designed typically for adult and older children populations, yet there remains a lack of assessment tools for younger children (< 7 years of age) despite a recent focus on this age range. Following previous testing and validation, the 26-item iteration of the Children’s Mathematics Anxiety Scale UK (CMAS-UK) for ages 4-7 years was further validated with 163 children (4-7 years) across 2 schools in the UK to test the validity and reliability of the items through subsequent exploratory and confirmatory factor analysis. The predictive validity of the scale was also tested by comparing scale scores against mathematics performance on a mathematics task to determine the relationship between scale and mathematics task scores. Exploratory Factor Analysis and associated Parallel Analysis indicated a 19-item scale solution with appropriate item loadings (>.45) and high internal consistency (α = .88). A single factor model of Online Mathematics Anxiety was related to the experience of an entire mathematics lesson, from first entering the classroom to completing a task. A significant negative correlation was observed between the CMAS-UK and mathematics performance scores, suggesting that children who score high for mathematics anxiety tend to score to perform less well on a mathematics task. Subsequent Confirmatory Factor Analysis was conducted to test a range of module structures; the shortened 19-item CMAS-UK was found to have similar model indices as the 26-item model, resulting in the maintenance of the revised scale. To conclude, the 19-item CMAS-UK provides a reliable assessment of children’s mathematics anxiety and has been shown to predict mathematics performance. This research points towards the origins of mathematics anxiety occurring when number is first encountered and supports the utility of the CMAS-UK. Subsequent research in the area should consider and appropriately define an affective component that may underlie mathematics anxiety at older ages. Mathematics anxiety relates to more complex procedures that elude the experiences of younger children and may instead be the result of number-based experiences in the early years of education.
POLITICAL ABSTENTION IN THE INDIAN MIDDLE CLASS, THE RISE OF POPULISM AND THE REINFORCEMENT OF RENT
Authors: Pal Arkaprabha
Published: October 2018

The Indian middle class witnessed a reconfiguration in its composition after the failure of the secular nationalists in their method of development and redistribution of resources. This reconfiguration used cultural and religious fundamentalism in the form of Hindutva as its instrument to assert their right to access the resources and strive towards a non-State centric redistribution. However, this new middle class, which was mainly conversing in the vernacular and had its base in the smaller urban areas, was also faced with the assertion of the lower class identarian groups. In such a situation, a large section of the urban Indian middle class shied away from taking part in the electoral process citing moral crises of the corrupt secular English speaking elite on one hand and the lowly criminal nature of the lower class political assertion on the other. Taking hints from the works of Christophe Jaffrelot, I would try to argue in this paper, that non-participation of a major section of the urban middle class was a manifestation of securing the rechanneled and partially redistributed rent legitimised through the instrument of Hindutva. This has led to increased persona-centric populist narratives from the mid-1990s to the present times with efforts to undermine parliamentary democracy (which is associated as an institiution of the immoral secular nationalists). This in turn, I would try to argue by the end of this paper, has again assisted in concretising the very rent-seeking practices and patron-client political relationships that the new middle class had initially opposed to rise to political prominence throughout the late 1970s and 1980s
'Welcome' Changes? Descriptive and Injunctive Norms in a Wikipedia Sub-Community
Authors: Morgan Jonathan T. , Filippova Anna
Published: October 2018

Open online communities rely on social norms for behavior regulation, group cohesion, and sustainability. Research on the role of social norms online has mainly focused on one source of influence at a time, making it difficult to separate different normative influences and understand their interactions. In this study, we use the Focus Theory to examine interactions between several sources of normative influence in a Wikipedia sub-community: local descriptive norms, local injunctive norms, and norms imported from similar sub- communities. We find that exposure to injunctive norms has a stronger effect than descriptive norms, that the likelihood of performing a behavior is higher when both injunctive and descriptive norms are congruent, and that conflicting social norms may negatively impact pro-normative behavior. We contextualize these findings through member interviews, and discuss their implications for both future research on normative influence in online groups and the design of systems that support open collaboration.
Impact of Employees Motivation on Organizational Performance
Authors: Dwibedi Lalan
Published: October 2018

Motivation and its impact on organizational performance has always remained highly researched area and have gone through many discussions and iterations. This paper identifies the factors that effects employee motivation and examines the relationship between organizational effectiveness and employee motivation. The study focuses on the practice and observance of the two central factors, empowerment and employee recognition for enhancing employee motivation which leads to organizational performance. So organizations should design their rules, policies and organizational structures that give space to the employee to work well and appreciate them on their tasks fulfillment and achievements. Higher the motivation among employee to task accomplishment higher will be the organizational performance and success.
