Sound Pressure Levels

The influence of acoustic characteristics of in-flight noise on airplane operations and sound impression has been investigated through objective and subjective measure including the flight simulation. The authors verified the influence of the noise conditions including seven conditions, in which the sound pressure levels and frequency characteristics of them were parametrically changed, on the airplane operations using shortterm flight simulation. Resultantly, the change of the sound pressure levels of the in-flight noise did not greatly affect the operation accuracy although clearly affected the subjective impressions. On the other hand, it has been suggested that the change of the frequency characteristics of in-flight noise affected not only the subjective impressions but also the operation accuracy.

The Belief-Desire-Intention (BDI) model is a popular approach to design flexible agents. The key ingredient of BDI model, that contributed to concretize behavioral flexibility, is the inclusion of the practical reasoning. On the other hand, researchers signaled some missing flexibility’s ingredient, in BDI model, essentially the lack of learning. Therefore, an extensive research was conducted in order to extend BDI agents with learning. Although this latter body of research is important, the key contribution of BDI model, i.e., practical reasoning, did not receive a sufficient attention. For instance, for performance reasons, some of the concepts included in the BDI model are neglected by BDI architectures. Neglecting these concepts was criticized by some researchers, as the ability of the agent to reason will be limited, which eventually leads to a more or less flexible reasoning, depending on the concepts explicitly included. The current paper aims to stimulate the researchers to re-explore the concretization of practical reasoning in BDI architectures. Concretely, this paper aims to stimulate a critical review of BDI architectures regarding the flexibility, inherent from the practical reasoning, in the context of single agents, situated in an environment which is not associated with uncertainty. Based on this review, we sketch a new orientation and some suggested improvements for the design of BDI agents. Finally, a simple experiment on a specific case study is carried out to evaluate some suggested improvements, namely the contribution of the agent’s “well-informedness” in the enhancement of the behavioral flexibility.

The chapter engages the outpouring of Brexit comedy as an important case study of the politics of humor. On one hand, the literature on comedy and politics has identified the subversive potential of jokes as a form of everyday resistance. On the other hand, sociological approaches have emphasized the role of stereotype and humiliation in jokes as part of a disciplinary function of humor. Building on these insights, the chapter reads prominent debates within comedy about Brexit as a vernacular form of politics. Jokes and satire perform and reperform discourses of identity. The chapter argues we should rephrase “Brexit comedy” or “the comedy of Brexit” as a socially consequential practice that teases at the (changing) social and political consensus.

High Sound

In contemporary cities, and usually without realizing it, the population has been exposed to high sound pressure levels, which besides causing discomfort, can lead to health problems. Considering that a large part of this noise comes from emission from motor vehicles, this research aims to evaluate the sound behavior in sound environments configured by voids in the urban fabric, in order to identify whether open spaces can act as attenuators of sound levels. To obtain the expected results, the methodology used was structured from a review of the state-of-the-art and computer simulations relating the variables that influence the formation of urban space and sound emission and propagation, taking as a case study an urban portion of the municipality of Vitória/ES. In parallel, questionnaires were applied to evaluate the user's perception of their exposure. The measurement results indicated that the sound pressure levels caused by traffic noise are above the limit tolerated limit by the NBR norm 10151:2000 for the daytime period. In turn, the results obtained from the population indicated that there is little perception of noise by the users of the spaces surveyed.

In this research, the writer was aimed to find out the types of code switching that used by English teacher based on gender inequality and the reasons of using code switching that used by English teacher based on gender inequality. The writer was conducted case study in qualitative method. In collecting the data, the writer used observation by using video recording and interview. The result of the research shows that the writer found three types from each teacher based on gender inequality by observation. The types are inter-sentential, intra-sentential and tag switching. In the other hand, each types that used by English teacher based on gender inequality was made in number percentages, for female English teacher are inter sentential code switching 54%, intra sentential code switching 38% and tag switching 8%. Moreover, for male English teacher are inter sentential code switching 42%, intra sentential code switching 41% and tag switching 18%. In the other words, interview was used to find out the reasons that used by English teacher based on gender inequality. The reasons are talking about particular topic, repetition, Interjection and Raising status.

Main Barrier

<p><strong>Purpose:</strong> The purpose of this paper is to identify and determine reasons why construction companies reject some of the request for proposals (RFPS) suitable for them. <br /><strong>Methodology/Approach:</strong> The research has several parts. Within the first part the list of reasons which lead to rejection of RFPS and thus potential client are identified. Then the comparison of differences between groups of rejected RFPS with different configuration is made. The last part of research use Pareto analysis to determine most obvious and most costly reasons of rejection of RFPS. <br /><strong>Findings:</strong> The paper identifies 12 reasons, why construction companies decline to prepare proposal for their potential clients. It also doesn’t confirm that configuration of RFPS has significant impact on the rejection of RFPS. Moreover the results on the other hand showed that insufficient trust represent the main barrier which influences the rejection of RFPS in selected company.<br /><strong>Research Limitation/implication:</strong> The main limitation of the research is that it is based on single case study. Although, the quantitative results have to be generalised very carefully, on the other hand paper provide list of the possible reasons why construction companies decline to compete for an offer. <br /><strong>Originality/Value of paper:</strong> The paper provides unique perspective because apart from traditional attitude, where only the submitted RFPS are evaluated, this paper analyses rejected RFPS and tries to identify and determine reasons why construction companies decide not to prepare proposal and thus reduce the possibility to acquire new contract.</p>

The Impact

The integration between art and science is required for the student in the department of architecture. This paper concentrates on the importance of integration between artistic skills and scientific abilities for the student to achieve high quality level of learning in the department of architecture in Iraq. It analyses the criteria of the architectural education and the educational method used. It demonstrates the integration relationship between art, science and architecture. It follows a descriptive analyses methodology to investigate the skills and abilities required for the student to cope with the criteria of architectural education. It conducted a case study on students in the department of architecture in Iraq to explore the impact of having these skills and abilities on the student’s progression. It explains why a few students only graduate with high grades. The results obtained showed that the integration between artistic skills and scientific abilities is very important for the students. On the other hand, developing the artistic skills is harder than developing the scientific abilities in architectural education.

The present study is part of a research about computational thinking and tangible robotics. A robot in development in Portugal, MI-GO robot, is part of the basis of this research. The objective is to determine the attitude of young students concerning tangible robots and to observe in what measure they contribute to the development of their STEM skills. On the other hand, it also aims to know what are the opinions of educators, teachers, and researchers concerning MI-GO's characteristics and what is their value, adequacy and suitability for the educational grades of young learners (from 5 to 10). The study consists on a qualitative approach based in a case study methodology, using the techniques of questionnaire and observation. At first the data reveal a clear adhesion to the robot and tangible programming by learners, and the researchers that analyzed the device consider it was a very adequate one and presented several suggestions to improve it.

The City

There have been two types of scholarly discussion on city branding. On the one hand, city branding has been conceptualised as a differentiation strategy of entrepreneurial cities involved in interspatial competition. On the other hand, researchers have recently emphasised the need to pay attention to increasingly pervasive and transformative forms of city branding, including branding as an urban policy and a form of planning. Drawing on a case study carried out in Helsinki, Finland, this article connects these two approaches by analysing Helsinki’s recent city branding endeavour in the context of the qualitative transformation of the entrepreneurial city. The article shows how city branding highlights and constitutes the city as an entrepreneurial platform and enabler bound up by the extended entrepreneurialisation of society.

The One

Schools are expected to be sites of caring, but there is evidence that both students and adults often experience them as uncaring places. One reason is that a sustained and heavy policy emphasis on accountability and demonstrations of effectiveness has placed pressure on educators to perform in certain ways, and to care about things other than caring. This case study explores how leaders and teachers at two schools balance their efforts to care for students, on the one hand, with the performative pressures they feel, on the other hand. Teachers who were able to prioritize a balance of care used collaborative relationships with colleagues to manage the pressure they felt, and took a longer term, more emotionally attuned, and more inquiry-based approach to meeting student needs. Implications for theory and practice are discussed.

In Memoriam

Tennyson's In Memoriam furnishes a case study, a vexed and difficult one, in the persistence of literary tradition. Though it is not, strictly speaking, a pastoral elegy, In Memoriam yet retains unmistakable markings of the traditional form. A. J. Carr, for one, has recently insisted upon the importance of pastoral motifs “to provide the personal themes of In Memoriam with a formal structure responsive to both private instinct and the elegiac traditions.” On the other hand, others as early as A. C. Bradley and as recently as Elton Edward Smith have offered what amounts to the opposite judgment on the significance of the pastoral tradition as a key to the structure of In Memoriam. In Smith's words, “the classical elegiac conventions are observed, but not in such a way as to provide either a framework for the whole or dividing lines within the work.”
