Statistical Evaluation on Neighborhood Facilities in Relation with Residential Satisfaction and Preference

This paper presents a study on the method of evaluating the residential environment in terms of neighborhood facilities and urban planning. Subjective evaluations through questionnaire survey were performed in order to grasp the resident’s behaviors and preferences. In 2013, questionnaires were distributed to more than 3,000 households of younger families located in Kitakyushu City, Northern Kyushu Island, Japan. In this study, we analyzed the result of questionnaires with the statistical method and performed some discussions. As results, several findings could be described as follow: (1) Almost of the respondent were still unsatisfied about the safety, even the safety level score has increased during 10 years; (2) more than 60% of households realized their comprehensive wish on living condition, which means the target of residential environment plan and design are nearly achieved; (3) the study on the model fitness shows that the evaluation system developed in this study captured most attributes that underlie residential environment and can offer a promising and valuable theoretical framework for the evaluation of residential environmental quality. Further, this paper also contributes some strategies on efficient planning and development of the residential environment.
Economic Analysis of Knowledge: The History of Thought and the Central Themes

Following the development of knowledge economies, there has been a rapid expansion of economic analysis of knowledge, both in the context of technological knowledge in particular and the decision theory in general. This paper surveys this literature by identifying the main themes and contributions and outlines the future prospects of the discipline. The wide scope of knowledge related questions in terms of applicability and alternative approaches has led to the fragmentation of research. Nevertheless, one can identify a continuing tradition which analyses various aspects of the generation, dissemination and use of knowledge in the economy.
Adaptation of Tabu Search for Optimisation of Biomass Waste to Energy Conversion Systems

We study the optimisation of a biomass waste to energy conversion system using an adapted Tabu Search heuristic. It corresponds to a non-linear and non-convex optimisation problem whose solution involves several optimisation sub-problems, including three with differential equations. In solving this complex optimisation problem, four contributions have been made to the adaptation of Tabu Search for use in the optimisation of biomass energy conversion systems. These are: multi-period and diversification strategies that lead to an effective search of the solution space, handling of constraints by development of different strategies for searching feasible regions, with some incursions into infeasible regions to find a shortcut towards feasible regions, and evaluation of a multi-objective function exploiting an approximation of the Pareto front. The results of the experiments show that the resulting Tabu Search heuristic, gives better solutions for this type of optimisation problem, compared to the basic Tabu Search. The developed Tabu Search was used to maximize revenue from biomass waste to energy conversion systems for two types of livestock (cows and swines). The Tabu Search was also used to identify the minimum herd size required for commercial viability of a biomass waste to energy conversion system. Experiments show that the adapted Tabu Search corresponds to a very useful tool for determination of commercial viability of biomass waste to energy conversion systems.
Measurement of the transverse coherence of a VUV Free Electron Laser

The transverse coherence is important for many applications of a free electron laser (FEL). It depends on the inner structure of the electron bunch in the undulator, which is difficult to measure. It is therefore essential to determine the coherence properties of the FEL radiation directly. The coherence of the vacuum ultraviolet FEL at the TESLA Test Facility has been measured by recording the diffraction pattern of a double slit and measuring the visibility of the interference fringes. The experimental near field diffraction pattern is compared with a numerical model, taking into account the formation of the FEL radiation, the Fresnel diffraction in the near field zone and effects of the experimental set-up. Diffraction patterns have been recorded for various effective undulator lengths to measure the evolution of the transverse coherence along the undulator. This is compared to the expected evolution of the transverse radiation modes.
Iterative Solution of Electromagnetic Scattering by Arbitrary Shaped Cylinders

─ The electromagnetic scattering analysis of geometrically complex structure has played an important role in electromagnetic field theory and practicable applications. The fast and rigorous methods to solve such problem are in great demand. In this work, the Wave Concept Iterative Process (WCIP) combined with a coordinate transformation has been extended to the scattering problems of electromagnetic conducting square cylinder, conducting super-ellipsoid and conducting super-ellipsoid coated with thin dielectric materials. Numerical results illustrate the efficiency of our approach. The radar cross section (RCS) is then reached and compared with the literature. Index Terms ─ Electromagnetic scattering, radar cross section, coordinate transformation, superellipsoid, wave concept iterative process (WCIP).
Economic Benefits of an Eco-Town for Slums in Dhaka City of Bangladesh: An Application of Discrete Choice Model

Environmental changes in general, and those associated with climate change in particular, are increasingly recognized as growing drivers of establishing the slums. Climatic victims come to slums of major cities of Bangladesh for resettlement. They have less job opportunity and bound to lead substandard life under the surrounding urban environment. Urbanization, in general, is frequently blamed for greenhouse gas (GHG) emissions and hence for climate change. From the production perspective, if cities concentrate energy intensive production, this will push up their average GHG emission per person. In addition, unplanned waste management and sanitation of slum pollute environment in several ways. Greater congestion of slums has already leaded to severe health and security problems. As a result, poor slums dwellers suffer a lot, and their livelihood standard degrades as well. Eco-town based green growth plays an important role to get rid of these unexpected environmental hazards and improve the livelihood condition of slum dwellers. This study is conducted through questionnaire survey (n = 327) in the major slums of the Dhaka city and attempts to apply choice experiment approach to assess consumer attitudes, that is, the preference and willingness to pay (WTP) for establishment of attributes of solar photovoltaic (PV) system, improved sanitation, waste collection, waste based biogas plant for transmission of gas for households and monthly payment at different levels of eco-town for environmental changes and livelihood diversifications. Random parameter logit and multinomial logit models are used to quantify the slum dwellers perceptions on the attributes of eco-town. Attributes of solar PV system, improved sanitation, and waste collection, educational attainment, and age are found statistically significant and positive. The estimate of WTP on solar PV is higher than the WTP on other attributes in the study area. The findings in this study provide a robust basis for both policy makers and government to make more specified policies to make a low carbon society and eradicate poverty in the urban slums. Aus.

Summer II 2014 EFFECTS OF SOCIO-DEMOGRAPHICAL FACTORS ON MASLOW ’ S NEEDS OF HIERARCHY : AN APPLICATION ON EDUCATORS IN DIFFERENT POSITIONS IN ANKARA

The aim of this study is to determine the effects of socio demographic factors of educators on each of Maslow’s needs via a Chi-Square analysis based, visual decision tree method. With this purpose, the effects of the socio-demographical factors such as gender, occupational status, year of experiences, brunch and education level among teachers, school directors, and inspectors on five motivational needs which are physiological, safety, love and belongingness, esteem and self-actualization described by Maslow (1943/1970) were examined by paired sample t test, Correlation analysis and Chi Squared Automatic Interaction Detection (CHAID) analysis. The study is based on randomly selected 2003 educators in Ankara-Turkey. Some descriptive statistics and figures that show the significant variables on educators’ needs are given in related tables and figures. According to the results of the analysis, while needs of Safety found the most important need with the mean score of 4,53 over 5, needs of belonging found less important than the other needs with the mean score of 4,01. Results show that these needs of the educator are not met enough. Meeting these needs is important for the educators to conclude their works more motivated. There found statistically significant correlations between all the needs of educators as a result of correlation analysis. There also found a significant difference between the needs of  This study is performed from Başak Cengiz Erdoğmuş’s M.S. thesis, supervised by Mustafa Aydın BAŞAR at Çanakkale Onsekiz Mart University, Institute of Social Sciences, 2007. 316 Sinan SARAÇLI & Mustafa Aydın BAŞAR & Başak CENGİZ ERDOĞMUŞ & Cengiz GAZELOĞLU the educators, as a result of the paired sample t test. Results of CHAID analysis showed that while the experience of the educators is the most important factor on Physiological Belonging and Self-Actualization needs, gender is the most important factor on Safety and Esteem needs.
Field determintation of young acid lime plants transpiration by the stem heat balance method

ABSTRACT: The stem heat balance method (HBM) measures sap flow (SF) in plants, and can be used toestimate daily transpiration flow. It is a powerful technique for water relations and irrigation field studies,but it has to be tested in species of particular interest. This paper discusses effectiveness of the HBM toestimate transpiration of young acid lime plants ( Citrus latifolia Tan. cv. Tahiti), grafted on citrumelo cv.Swingle ( Poncirus trifoliata Raf. x C. paradisi Macf.), in the field using commercial gauges (model SAG10-ws, Dynamax Inc., Huston), in Piracicaba, State of Sao Paulo, Brazil. SF was correlated to transpirationdetermined by weighing lysimeters and by a steady-state null-balance porometer. The mean ratio betweendaily values of SF and lysimetric measurements was practically unitary, showing a mean difference ofonly 0.05%, being the comparisons of values in periods shorter than 24 hours impaired by effect of windturbulence on lysimeters. The same occurred (mean difference of 0.38%) when SF and canopy transpirationestimated from porometer measurements were compared in 20-min periods, but transpiration tended toexceed SF in periods of higher transpiration and data dispersion was high (r
Pathwise Iteration for Backward SDEs

We introduce a novel numerical approach for a class of stochastic dynamic programs which arise as discretizations of backward stochastic differential equations or semi-linear partial differential equations. Solving such dynamic programs numerically requires the approximation of nested conditional expectations, i.e., iterated integrals of previous approximations. Our approach allows us to compute and iteratively improve upper and lower bounds on the true solution starting from an arbitrary and possibly crude input approximation. We demonstrate the benefits of our approach in a high dimensional financial application.
Engaging the Learner: How Can the Flow Experience Support E-learning?

This paper describes research into making e-learning activities motivating and engaging, yet still producing effective learning. Flow is used as an underlying theory to explore student behaviour during online instruction. In this study, 59 students worked through a learning exercise in physics while two different methods were employed to measure flow experiences. Graphical visualisations (‘flow path’ plots) were employed to show the dynamic nature of the students’ experiences. These were found to be inconsistent with other traditional flow measurement techniques. The study identified the students’ changing focus between task and artefact as a contributor to this inconsistency. A significant contribution of this paper is the identification of ‘task-flow’ and ‘artefact-flow’ and their significance in e-learning.
COAGULASE POSITIVE ENTEROTOXIGENIC STAPHYLOCOCCUS AUREUS COUNT IN PARAGUAY SEMI-HARD CHEESE

Background: One of the foodborne diseases of high incidence in the Latin American region is Staphylococcal intoxication, due to food contaminated with enterotoxins produced mainly by Staphylococcus aureus. The aim of this study was to enumerate, isolate and characterize S. aureus enterotoxigenic in Paraguay cheeses obtained at markets in Paraguayan cities. Methods: Three hundred eighty-two cheese samples were analyzed according to ISO 6888-1. Biochemical test, enterotoxin production ability and genotype characterization by PCR multiplex were performed to isolate. Results: Eight point thirty-seven percent of samples contained typical colonies of coagulase-positive S. aureus. Fourteen strains had the gene encoding enterotoxin A. Conclusion: The presence of coagulase-positive S. aureus in the cheese samples revealed a latent state of staphylococcal food poisoning outbreaks in Paraguay. Type A enterotoxigenic S. aureus is the most frequent isolation in this type of products, and multiplex PCR method is an effective and fast identification technique.
A Heuristic Algorithm for Solving Triangle Packing Problem

The research on the triangle packing problem has important theoretic significance, which has broad application prospects in material processing, network resource optimization, and so forth. Generally speaking, the orientation of the triangle should be limited in advance, since the triangle packing problem is NP-hard and has continuous properties. For example, the polygon is not allowed to rotate; then, the approximate solution can be obtained by optimization method. This paper studies the triangle packing problem by a new kind of method. Such concepts as angle region, corner-occupying action, corner-occupying strategy, and edge-conjoining strategy are presented in this paper. In addition, an edge-conjoining and corner-occupying algorithm is designed, which is to obtain an approximate solution. It is demonstrated that the proposed algorithm is highly efficient, and by the time complexity analysis and the analogue experiment result is found.
Retailer-Supplier Relationship in Hong Kong: Asymmetry, Power Play, and Supply Chain Management

This study investigates the characteristics of retailer-supplier relationship in Hong Kong, identify problems in it, and suggest ways to remedy them. We will demonstrate that Hong Kong’s retail industry was and is dominated by small and medium sized retailers. However, small retailers in Hong Kong have not sufficiently adopted new retail technologies to manage their supply chains. This situation is undermining the efficiency of Hong Kong’s retail industry. We recommend information systems providers, the management of small retailers, and suppliers to take steps to improve supply chain efficiency for small retailers. Information systems providers can help through designing affordable implementation and common modules. Suppliers in Hong Kong can actively build network, cultivate trust, and equip themselves with advanced information systems. Small and medium sized retailers in Hong Kong need to invest sufficient resources to implement retail information systems.
Statistical analysis of conformational properties of periodic dinucleotide steps in nucleosomes

Deformability of DNA is important for its superhelical folding in the nucleosome and has long been thought to be facilitated by periodic occurrences of certain dinucleotides along the sequences, with the period close to 10.5 bases. This study statistically examines the conformational properties of dinucleotides containing the 10.5 - base periodicity and those without that periodicity through scanning all nucleosome structures provided in PDB. By categorizing performances on the distribution of step parameter values, averaged net values, standard deviations and deformability based on step conformational energies, we give a detailed description as to the deformation preferences correlated with the periodicity for the 10 unique types of dinucleotides and summarize the possible roles of various steps in how they facilitate DNA bending. The results show that the structural properties of dinucleotide steps are influenced to various extents by the periodicity in nucleosomes and some periodic steps have shown a clear tendency to take specific bending or shearing patterns.
Do Speakers' Vocal Tract Geometries Shape their Articulatory Vowel Space?

This study investigates the relation between parameters describing differences between speaker-specific vocal tract geometries and articulatory distances between the corner vowels based on MRI data of 9 French speakers. Results provide evidence that speaker with a longer pharynx produce larger displacements between low back and high front vowels. Preliminary modeling results are also presented with the aim to study the relation between motor commands, articulation and acoustics.
Morphological variation of Philodryas patagoniensis (Girard, 1858) (Serpentes, Dipsadidae) from Brazil, based on the study of pholidosis, coloration and morphometric features

The current study aimed to verify the relationship between the patterns of coloration, the morphometrical features and pholidosis of specimens of Philodryas patagoniensis from Brazil, with the sexual dimorphism of this species. We studied specimens of P. patagoniensis deposited in several herpetological collections from Brazil. A total of 355 specimens were analyzed, of these 145 were males (87 adults and 58 juveniles) and 210 were females (134 adults and 76 juveniles). Adult specimens exhibit sexual dimorphism in snout-vent length, tail length, head length, number of ventral shields, and number of subcaudal shields. The analysis of variance showed that the adult females are significantly longer than adult males, both at snout-vent length and tail length. Females have a greater number of ventral shields (138-210) than males (151-200). The specimens studied also exhibit two distinct patterns of coloration unrelated to geographical or sexual variations.
The Psychology of Two-Part Tariffs

This paper investigates preferences for two-part tariff pricing plans which require consumers to pay a flat fee plus a per unit surcharge for usage beyond an allowance. People have difficulty estimating the effective cost of a two-part tariff, so they apply heuristics to the most salient attributes. Compared to a normative benchmark of expected cost, these heuristics lead people to excessively choose plans with smaller flat fees, larger usage allowances, and lower overage rates. When these attributes are in conflict, people assign greater importance to comparisons of the two attributes that provide upside protection against overage charges: the usage allowance and the overage rate. The presence of usage uncertainty heightens the reliance on these comparisons, and calculating a cost does not appear to reduce them.

Full scale experiments on the effectiveness of a drainage system for cemented paste backfill

This paper presents full-scale experiments on cemented paste backfilling in two operating mine stopes located at Raleigh mine, Kalgoorlie, Western Australia. The experiments compared the behaviour of the cemented paste backfill (CPB) in a drained stope and an undrained stope. The drained stope was equipped with a drainage system at the barricade, whereas the undrained stope was not. Total stress and pore water pressure sensors were installed to measure the stress within the fill mass during and after backfilling. The stress behaviour was expressed by the normalised total horizontal pressure and the normalised pore water pressure. It was found that the normalised total horizontal pressure and the normalised pore water pressure behaviour at the two stopes were significantly different. The drainage system increased the consolidation of the fill and reduced the pressure acting on the barricade. The pore water pressure measurement in the undrained stope showed a non-linear accumulation at the barricade. In contrast with the undrained stope, the stope with the drainage system showed significant pore water pressure reduction and the accumulation of pore water pressure at the barricade no longer occurred. The findings described in the paper contribute to critical design and management aspects such as barricade stress, filling rate, and curing strategy, with an ultimate goal of reducing costs while ensuring safety underground.
Symmetric exclusion as a model of non-elliptic dynamical random conductances

We consider a finite range symmetric exclusion process on the integer lattice in any dimension. We interpret it as a non-elliptic time-dependent random conductance model by setting conductances equal to one over the edges with end points occupied by particles of the exclusion process and to zero elsewhere. We prove a law of large number and a central limit theorem for the random walk driven by such a dynamical field of conductances using the Kipnis-Varhadan martingale approximation. Unlike the tagged particle in the exclusion process, which is in some sense similar to this model, this random walk is diffusive even in the one-dimensional nearest-neighbor symmetric case.
Thermodynamic Interactions of Nb and Mo on Ti in Liquid Iron

Thermodynamic interactions of niobium and molybdenum on titanium in liquid iron were studied in the temperature range of 1873� 1973 K by measuring the effects of niobium and molybdenum on the solubility product for TiN formation in liquid iron using the metalnitride-gas equilibration technique. The experimental results were thermodynamically analyzed using Wagner’s interaction parameter formalism to determine the first-order interaction parameters of niobium and molybdenum on titanium in liquid iron as 0:0495 � 0:0049 and 0:01 � 0:0026, respectively, at 1873 K. Temperature dependence of these parameters was also determined as follows. e Nb ¼ 1160=T � 0:570; e Mo ¼ 0:01 ð1873� 1973 KÞ
