Abstract:
What makes an asset a “safe” asset? We study a model where two countries each issue sovereign bonds to satisfy investors’ safe asset demands. The countries differ in the float of their bonds and the fundamental resources available to rollover debts. A sovereign’s debt is safer if its fundamentals are strong relative to other possible safe assets, not merely strong on an absolute basis. If demand for safe assets is high, a large float enhances safety through a market depth benefit. If demand for safe assets is low, then large debt size is a negative as rollover risk looms large.

Abstract:
Besides the energy efficiency approach to reduce energy demands of production systems there are also other possibilities to decrease the energy related operating costs. Amongst others avoiding long-term peak loads represents a common measure. In possible future cases a flexible energy demand of factories can also be refunded by the energy provider within new tariff structures. This paper shows the potentials of production systems to alternate their energy demand within productive state, which is also referred to as technical energy flexibility. The focus is on machines of sensitive main processes, where an influence on the energy demand could induce distinct negative effects on the product quality. It is shown how and to which extent the energy demand of production systems can be controlled without negative effects.

Abstract:
The demand for money is the key element uniting major structural models of exchange rate determination. The author analyzes the history of money demand theorizing in connection with the development of structural models of exchange rate determination. The author demonstrates that the evolution of the theory of money demand shaped the evolution of the theory of exchange rate. The paper also contains suggestions regarding the approach to criticizing structural exchange rate determination models on methodological grounds and the manner of teaching the economics of exchange rates.

Abstract:
Many liberal theorists misinterpret nationality and the demand for national self-determination. This paper asks what is the claim for national self-determination. Following this, it is asked which way of meeting the demand is the best one. While analysing the circumstances in which the demand is raised, it is argued that this claim is political rather than cultural, and that therefore some of the solutions which have been put forward in theory and in practice (especially autonomy) do not meet this claim. It is also argued that the failure of many Western politicians and political theorists to address the demand for national self-determination as a political demand derives from three reasons: methodological, moral and ideological.

Hill, David W. "Determination of Accumulated O2 Deficit in Exhaustive Short-Duration Exercise." Canadian Journal of Applied Physiology 21, no. 1 (February 1, 1996): 63–74. http://dx.doi.org/10.1139/h96-006.

Full text
Abstract:
Usually, an initial step in determining accumulated O2 deficit is the estimation of the O2 demand of high intensity exercise by extrapolation from [Formula: see text] measured during steady-state submaximal exercise. It was hypothesized that O2 deficit could be determined without the need to estimate O2 demand by extrapolation. Ten women performed all-out cycle ergometer exercise tests at each of four power outputs selected so that exhaustion would occur after 90 to 600 s. Power output (W), accumulated VO2 (ml), and time to exhaustion (s) were measured in each test and then fit to the following equation: O2 deficit (ml) = O2 demand (ml∙min−1∙W−1)∙time (min)∙power (W) - accumulated VO2 (ml). This procedure generated values for two parameters (O2 demand and O2 deficit) for each subject. The O2 deficit was also calculated for each individual using conventional methods. The values for O2 deficit obtained using the two methods were correlated (r =.96, p <.01), and the value obtained using the experimental method tended to be larger, t(9) = 2.15, p =.06. It is concluded that O2 demand and O2 deficit can be determined from the results of several high-intensity tests without the need to extrapolate from submaximal exercise to estimate the O2 demands of supramaximal exercise.

Abstract:
Green building is the modern method adopted to attain global sustainability through individual house level. The user’s demand for housing is increasing every day, also the demand for other house utility increases. These demands may include energy and water supply, refuse management, provision of new infrastructures etc. most of these demands are necessary for every user to survive. Therefore, most users engage in afforestation, increases carbon emission and rise in the Greenhouse gases level production to meet up with their demands, these activities causes’ disasters to our planet. Therefore users need and green approach to sustainability are two opposite factors. This paper examines the user’s need and comfort in designing or purchasing green buildings in Kano state, Nigeria. Relevant kinds of literature were revised in this work with the addition of a case study which was analysed using the descriptive approach method. A case study was picked in Kano state, Gwale Yan-Alawa quarters as an example of green building, which was analysed and rated using BREEAM and LEED assessment criteria. The result shows about 80% of user satisfaction was recorded. Also, the demand for green building keeps increasing in Kano state, which adds value to it. Keywords: Green building, users’ need, users’ demand, users’ perception, sustainability and green construction

This economics is not merely economics but also discusses about many spheres of the labors. Labor economics look out to recognize the dynamics and functions of the markets of labor. The labor market function is by the interaction and dealing of employers and workers. Labor economics tries to understand the result pattern of income, employment and wages by looking at the workers or employs and labor is the measurement of the work that is done by the human beings. Usually, there is dissimilarity in labor economics and other aspects of production such as capital and land. In this article we will discuss about the spheres of this field of economics.

Abstract:
Chlorination is the most practical way for the destruction of pathogenic and other harmful organisms in water and wastewater treatment plants. However, highly erratic concentrations of ammonia is contained in most water and wastewater treatment plants, which will react to chlorine and seriously alter the required chlorine dosages in the control of chlorination. The conventional control of chlorine dosage is widely practical throughout the batch breakpoint chlorination test in the laboratory, which is not feasible for the requirement of real-time regulation of the chlorine demands. In this study, a simple automatic oxidation-reduction potential (ORP) titration system was developed for on-line determination of the chlorine demand. The experimental results showed that different decrease tendencies on ORP slope profiles were found to correlate to the ammonia concentrations in samples. In addition, the required chlorine demands were found to correlate to ammonia concentrations with a linear relationship. The ORP control strategy was, therefore, developed for on-line determination of the chlorine demands. Applying this ORP control strategy, the required chlorine demands were precisely predicted, and good disinfection efficiency was obtained in the wastewater chlorination experiments.

Abstract:
An RC frame school building was designed with lower fortification requirements than required. It collapsed in the 2008 Ms8.0 Wenchuan earthquake. This study evaluated the building’s deficiency and practiced a retrofit design based on traditional demand-capacity method but with a displacement-based (DB) procedure, in which target capacities were obtained from the equivalent single-degree-of-freedom (ESDOF) systems defined by target mode shapes of the MDOF system, and shear demands were assessed using an R- μ- T relationship to match different capacity levels. To make the DB procedure code-conforming, the retrofitting elements (BRBs) were simplified as bi-linear elements, with the two-phase parameters corresponding to the code’s two-stage requirements. Shear distribution to the MDOF building was also determined by displacement shapes. BRBs’ stiffness demands and sizes were from the difference of the required and available shear resistances. The effectiveness of the method was validated by time history analyses. Different earthquake level simulations showed that, the method realized the design goals but did not lead to over-retrofitting; the BRBs took most of the shear demand but would not induce other unexpected failures. So the method was suitable for retrofitting similar structures.

Abstract:
We propose and estimate a novel specification of labor demand which encompasses search frictions and the role of entrepreneurs in new firm creation. Using city-industry variation over four decades, we estimate the wage elasticity of employment demand to be close to −1 at the industry-city level and −0.3 at the city level. We argue that the difference between these estimates reflects the congestion externalities predicted by the search literature. Our estimates also indicate that entrepreneurship should be treated as a scarce factor in the determination of labor demand. We use our estimates to evaluate the impact of large changes in the minimum wage on employment. (JEL J23, J31, J38, L26, M13, R23)

Abstract:
Respecting the principles of analytics, systematization and comprehensiveness, the paper deals with the frames of disparity between supply and demand in services market. The basic reasons for disparity are systematically divided into five groups: (1) reasons for problems in the area of information on supply and demand, (2) reasons for problems in the area of parallel functioning of the gray market, (3) reasons for problems in the area of psychological conditions and perceptions of consumers, (4) reasons for problems in the area of social and economic situation, (5) reasons in the area of institutional functioning. These groups contain reasons of the general character and reasons in individual areas and flows. The analysis of disparity has been conducted via relevant relations of demand and supply that exist in services market, as follows: (1) the relation of supply of services provided by companies towards adequate forms of demand (other companies, institutions, population), (2) the relation of institutions' supply of services toward adequate forms of demand (all companies, population) and (3) the relation of unofficial supply of services toward adequate demand (population). Within basic prerequisites for the solution to disparity of demand and supply in the service sector, we have especially emphasized and analyzed personnel potential. We have analyzed elements and problems of the labor market, available personnel potential (personnel potential of the employed and the unemployed), as well as latent personnel potential.

This paper uses econometric multiple regression techniques in order to analyze the socioeconomic factors affecting the demand for abortion for the year 1985. A cross-section of the 50 states and Washington D.C. is examined and a household choice theoretical framework is utilized. The results suggest that average price of abortion, disposable personal per capita income, percentage of single women, whether abortions are state funded, unemployment rate, divorce rate, and if the state is located in the far West, are statistically significant factors in the determination of the demand for abortion.

Full text
Abstract:
The paper is focused on the derivation of the mathematical relationship among the income-elasticity level of the entire market demand and the income-elasticity values of the demand functions of the consumers&rsquo; groups buying on the defined market. The determination of the mathematical term was based on the linearity of the relevant demand functions. Under the linearity assumption, the income elasticity coefficient of the entire market demand equals the weighted sum of the income-demand elasticities of the differentiated consumer groups buying on the given market. The weights in the aggregation formula are defined as the related demand shares, i.e. as the proportions of the groups&rsquo; demands to the entire market demand. The derived aggregation equation is quite held if no demand interactions (e.g. the snob or fashion effect) are recorded among differentiated consumers&rsquo; groups. The derived formula was examined by using empirical data about the consumer behaviour of Czech households in the market of meat and meat products (Czech Statistical Office). However, the application potential of the achieved term for the income-elasticity aggregations is much broader within the consumer-behaviour analysis. In addition to the subject aggregations of the demand functions, we can also apply the derived formula for the analysis and estimations of the income elasticities within the demand-object aggregations, i.e. the multistage analysis of the income elasticity of consumer demand. Another possibility of the use of the aggregation equation is for the evaluations and estimations of the income elasticity of the region-demand functions in relation to the subregions&rsquo; demands or reversely.

Abstract:
The contemporary manufacturing industries highly depend upon the change in customer needs and also focus on their varying demands across the supply chain. The uncertain demand and supply factor paves the successful supply chain of the manufacturing organization. The manufacturing organizations themselves imply many quality principles to withstand in the competitive market. This article deals with the selection of best suitable alternative for the case supply chain using Fuzzy Analytical Network Process (ANP). The advantage of using Fuzzy ANP is the selection of best suitable alternative by considering various interdependent values across the supply chain and also overcome vagueness associated with the computation.

Full text
Abstract:
Allocation and management of agricultural water resources is an emerging concern due to diminishing water supplies and increasing water demands. To achieve economic, social, and environmental goals in a specific irrigation district, decisions should be made subject to the changing water supply and water demand—the two critical random parameters in agricultural water resources management. This paper presents the foundations of a systematic framework for agricultural water resources management, including determination of distribution functions, joint probability of water supply and water demand, optimal allocation of agricultural water resources, and evaluation of various schemes according to agricultural water resources carrying capacity. The maximum entropy method is used to estimate parameters of probability distributions of water supply and demand, which is the basic for the other parts of the framework. The entropy-weight-based TOPSIS method is applied to evaluate agricultural water resources allocation schemes, because it avoids the subjectivity of weight determination and reflects the dynamic changing trend of agricultural water resources carrying capacity. A case study using an irrigation district in Northeast China is used to demonstrate the feasibility and applicability of the framework. It is found that the framework works effectively to balance multiple objectives and provides alternative schemes, considering the combinatorial variety of water supply and water demand, which are conducive to agricultural water resources planning.

Abstract:
Job demand resource model and self-determination theory is widely used for understanding procrastination, mindfulness, job performance and gender in organizational settings. The job demand resource model has been further used to understand gender as moderator among employee’s with mindfulness, procrastination and job performance. The present study focuses on gender as moderator in mindfulness, procrastination and job performance among male and female employees. The Purposive sampling technique with cross-sectional approach was applied. Mindfulness Attention Awareness Scale (MAAS; Brown & Ryan, 2003), Tuckman’s Procrastination Scale (TPS; Tuckman, 1991), and Job Performance Scale (JP-S; Wright, Kacmar, Mcmahan, &Deleeuw, 1995) were used to collect data from 400 employees working in telecom organizations in Rawalpindi and Islamabad city. The t-test and Hayes process were used to study correlation and moderation among study variables. It has been found female employees have mindfulness and procrastination tendencies then male employees whereas male employees were higher on job performance then female employees. Additionally, gender has non-significant effect on mindfulness, procrastination and job performance among employees. The results support the job resource demand model and self-determination theory. According to JDR model, job demands, and resources play important role in job performance of an employee in organizations and self-determination theory supports that mindfulness inhibit procrastination behavior and improve job performance of employees in organizations. These findings also suggest that procrastination could inhibit job performance among employees. Therefore, job performance could be stimulated by individual mindfulness in male and female employees.

Abstract:
There are many trade time series parade having seasonality. This paper ponders on taking the appropriate smoothing constants of seasonal time series data using Holt-Winter’s exponential smoothing method in demand forecasting of toy production in a company. It is a quantitative technique in forecasting. This forecasting method is used three constants that assign weights to current demands and previous forecasts to decide on a new forecast. We have demonstrated the techniques how to choose these constants by presenting a real life example and calculated corresponding forecast value of this technique for the optimal smoothing constants.

Abstract:
To determine the inter-regional power replacement, this paper starts from the inter-regional power transmission and out-purchased demands and puts forward the analysis models of power transmission and out-purchased. Then it focuses on the decision problem of inter-regional power transmission and out-purchased where power supply exceeds power demand and provide the corresponding optimization algorithm. The models shows that inter-regional power replacement can reduce the generation pollutants emission, promote the power efficiency, and raise renewable energy grid-connected content like hydropower, wind power and so on, making magnificent economy and environmental effects.

Abstract:
Abstract The paper presents the results of an experiment conducted on two cargo ships – a 5300 TEU container with a steam heating system and a 7500 dwt general cargo ship with a thermal oil system. On both ships research has been carried out using specially designed measuring equipment. After gathering data about flow velocity and temperatures (steam/ cooling water/ thermal oil/ seawater/ outside air), calculations have been done, resulting in histograms. For both types of histograms (heat demand and service time), the probability density function was fitted, using the K-S statistical test. The last step was comparison of the probability distribution mean to seawater and the outside air temperatures by linear regression and the coefficient of determination. The dependencies between the mentioned temperatures and heat demand were noted.

Abstract:
The Atlanta Regional Commission (ARC) regional travel demand model is described as it relates to its link-based emissions postprocessor. In addition to conformity determination, an overview of other elements is given. The transit networks include the walk and highway access links. Trip generation addresses trip production, trip attraction, reconciliation of productions and attractions, and special adjustments made for Hartsfield Atlanta International Airport. Trip distribution includes the application of the composite impedance variable. In the mode choice model, home-based work uses a logit function, whereas nonwork uses information from the home-based work to estimate modal shares. Traffic assignment includes preparation of time-of-day assignments. The model assigns single-occupancy vehicles, high-occupancy vehicles, and trucks by using separate trip tables. The procedures can accept or prohibit each of the three types of vehicles from each highway lane. Feedback between the land use model and the traffic model is accounted for via composite impedances generated by the traffic model and is a primary input to the land use model DRAM/EMPAL. The land use model is based on census tract geography, whereas the travel demand model is based on traffic analysis zones that are subareas within census tracts. The ARC model has extended the state of the practice by using the log sum variable from mode choice as the impedance measure rather than the standard highway time. This change means that the model is sensitive not only to highway travel time but also to highway and transit costs.
