    Full Text Available City logistics is a field that attracts increasing attention of professionals and scientific community and international organizations. Research on problems of urban areas' logistics gives different results and practical solutions. City logistics flows are characterized by partiality, spatial dispersion of generators, diversity in terms of the logistics chains structure, frequency of a large number of smaller shipments, dynamism, stochasticity etc. Problems and the complexity of logistics in urban areas as well as significant decline in the quality of life in modern cities have caused the development of initiatives and concepts of city logistics which should allow the sustainable development of urban areas. The first part of this paper presents the problems of city logistics and impact of logistics activities on urban areas in terms of economic, environmental and social sustainability. The second part presents city logistics initiatives that involve the change of urban area context, in order to improve its sustainability.

    It is recognized that handling uncertainty is essential to obtain more reliable results in modeling and computer simulation. This paper aims to discuss the logistic equation subject to uncertainties in two parameters: the environmental carrying capacity, K, and the initial population density, N0. We first provide the closed-form results for the first probability density function of time-population density, N(t), and its inflection point, t*. We then use the Maximum Entropy Principle to determine both K and N0 density functions, treating such parameters as independent random variables and considering fluctuations of their values for a situation that commonly occurs in practice. Finally, closed-form results for the density functions and statistical moments of N(t), for a fixed t > 0, and of t* are provided, considering the uniform distribution case. We carried out numerical experiments to validate the theoretical results and compared them against that obtained using Monte Carlo simulation.

    2010-12-01

    Groundwater has been used a main source to provide a drinking water in a rural area with no regional potable water supply system in Korea. More than 50 percent of rural area residents depend on groundwater as drinking water. Thus, research on predicting groundwater pollution for the sustainable groundwater usage and protection from potential pollutants was demanded. This study was carried out to know the vulnerability of groundwater nitrate contamination reflecting the effect of land use in Nonsan city of a representative rural area of South Korea. About 47% of the study area is occupied by cultivated land with high vulnerable area to groundwater nitrate contamination because it has higher nitrogen fertilizer input of 62.3 tons/km2 than that of country’s average of 44.0 tons/km2. The two vulnerability assessment methods, logistic regression and DRASTIC model, were tested and compared to know more suitable techniques for the assessment of groundwater nitrate contamination in Nonsan area. The groundwater quality data were acquired from the collection of analyses of 111 samples of small potable supply system in the study area. The analyzed values of nitrate were classified by land use such as resident, upland, paddy, and field area. One dependent and two independent variables were addressed for logistic regression analysis. One dependent variable was a binary categorical data with 0 or 1 whether or not nitrate exceeding thresholds of 1 through 10 mg/L. The independent variables were one continuous data of slope indicating topography and multiple categorical data of land use which are classified by resident, upland, paddy, and field area. The results of the Levene’s test and T-test for slope and land use were showed the significant difference of mean values among groups in 95% confidence level. From the logistic regression, we could know the negative correlation between slope and nitrate which was caused by the decrease of contaminants inputs into groundwater with

    Full Text Available City is the place of the largest concentration of economic and social activities, and the delivery of goods is a prerequisite for the maintenance of urban life and business activities for achieving wealth and development of the city. Logistics systems and processes that enable the realization of commodity flows support employment and generate income, but may also have negative impacts on all essential functions of the city. Therefore, logistics plays an important role in the competitiveness of urban areas and should be an integral part of the city's economy. From the perspective of sustainable development, i.e. social, environmental and economic efficiency, logistics processes primarily urban freight transport, are far from optimal. The growth of road freight transport and traffic congestion, air pollution and other negative impacts on the environment, inefficient use of land and the rising costs of delivery of goods affect the definition and exploration of different initiatives of city logistics. This paper describes the initiatives that do not require large infrastructure investments and do not change the existing urban context, but can improve its sustainability.

  15. Desertification Susceptibility Mapping Using Logistic Regression Analysis in the Djelfa Area, Algeria

    Full Text Available The main goal of this work was to identify the areas that are most susceptible to desertification in a part of the Algerian steppe, and to quantitatively assess the key factors that contribute to this desertification. In total, 139 desertified zones were mapped using field surveys and photo-interpretation. We selected 16 spectral and geomorphic predictive factors, which a priori play a significant role in desertification. They were mainly derived from Landsat 8 imagery and Shuttle Radar Topographic Mission digital elevation model (SRTM DEM. Some factors, such as the topographic position index (TPI and curvature, were used for the first time in this kind of study. For this purpose, we adapted the logistic regression algorithm for desertification susceptibility mapping, which has been widely used for landslide susceptibility mapping. The logistic model was evaluated using the area under the receiver operating characteristic (ROC curve. The model accuracy was 87.8%. We estimated the model uncertainties using a bootstrap method. Our analysis suggests that the predictive model is robust and stable. Our results indicate that land cover factors, including normalized difference vegetation index (NDVI and rangeland classes, play a major role in determining desertification occurrence, while geomorphological factors have a limited impact. The predictive map shows that 44.57% of the area is classified as highly to very highly susceptible to desertification. The developed approach can be used to assess desertification in areas with similar characteristics and to guide possible actions to combat desertification.

    Full Text Available The process of globalization has stimulated the demand for logistics services at a level of speed and increased efficiency, which involves using of techniques, tools, technologies and modern models in supply chain management. The aim of this research paper is to present a model that can be used in order to achieve an optimized supply chain, associated with minimum transportation costs. The utilization of spatial modeling for determining the optimal locations for logistics centers in a predefined economic area is proposd in this paper. The principal methods used to design the model are mathematic optimization and linear programming. The output data of the model are the precise placement of one up to ten logistics centers, in terms of minimum operational costs for delivery from the optimum locations to consumer points. The results of the research indicate that by using the proposed model, an efficient supply chain that is consistent with optimization of transport can be designed, in order to streamline the delivery process and thus reduce operational costs

  17. Estimating a Logistic Discrimination Functions When One of the Training Samples Is Subject to Misclassification: A Maximum Likelihood Approach.

    Directory of Open Access Journals (Sweden)

    Nico Nagelkerke

    Full Text Available The problem of discrimination and classification is central to much of epidemiology. Here we consider the estimation of a logistic regression/discrimination function from training samples, when one of the training samples is subject to misclassification or mislabeling, e.g. diseased individuals are incorrectly classified/labeled as healthy controls. We show that this leads to zero-inflated binomial model with a defective logistic regression or discrimination function, whose parameters can be estimated using standard statistical methods such as maximum likelihood. These parameters can be used to estimate the probability of true group membership among those, possibly erroneously, classified as controls. Two examples are analyzed and discussed. A simulation study explores properties of the maximum likelihood parameter estimates and the estimates of the number of mislabeled observations.

    Through the National Renewable Energy Laboratory (NREL), the United States Department of Energy (DOE) implemented the Wind Partnership for Advanced Component Technologies (WindPACT) program. This program will explore advanced technologies that may reduce the cost of energy (COE) from wind turbines. The initial step in the WindPACT program is a series of preliminary scaling studies intended to determine the optimum sizes for future turbines, help define sizing limits for certain critical technologies, and explore the potential for advanced technologies to contribute to reduced COE as turbine scales increase. This report documents the results of Technical Area 2-Turbine Rotor and Blade Logistics. For this report, we investigated the transportation, assembly, and crane logistics and costs associated with installation of a range of multi-megawatt-scale wind turbines. We focused on using currently available equipment, assembly techniques, and transportation system capabilities and limitations to hypothetically transport and install 50 wind turbines at a facility in south-central South Dakota.

    Logistic regression analysis examines the influence of various factors on a dichotomous outcome by estimating the probability of the event's occurrence. Logistic regression, also called a logit model, is a statistical procedure used to model dichotomous outcomes. In the logit model the log odds of the dichotomous outcome is modeled as a linear combination of the predictor variables. The log odds ratio in logistic regression provides a description of the probabilistic relationship of the variables and the outcome. In conducting logistic regression, selection procedures are used in selecting important predictor variables, diagnostics are used to check that assumptions are valid which include independence of errors, linearity in the logit for continuous variables, absence of multicollinearity, and lack of strongly influential outliers and a test statistic is calculated to determine the aptness of the model. This study used the binary logistic regression model to investigate overweight and obesity among rural secondary school students on the basis of their demographics profile, medical history, diet and lifestyle. The results indicate that overweight and obesity of students are influenced by obesity in family and the interaction between a student's ethnicity and routine meals intake. The odds of a student being overweight and obese are higher for a student having a family history of obesity and for a non-Malay student who frequently takes routine meals as compared to a Malay student.

    Logistic regression was used to develop statistical models that can be used to predict the probability of debris flows in areas recently burned by wildfires by using data from 14 wildfires that burned in southern California during 2003-2006. Twenty-eight independent variables describing the basin morphology, burn severity, rainfall, and soil properties of 306 drainage basins located within those burned areas were evaluated. The models were developed as follows: (1) Basins that did and did not produce debris flows soon after the 2003 to 2006 fires were delineated from data in the National Elevation Dataset using a geographic information system; (2) Data describing the basin morphology, burn severity, rainfall, and soil properties were compiled for each basin. These data were then input to a statistics software package for analysis using logistic regression; and (3) Relations between the occurrence or absence of debris flows and the basin morphology, burn severity, rainfall, and soil properties were evaluated, and five multivariate logistic regression models were constructed. All possible combinations of independent variables were evaluated to determine which combinations produced the most effective models, and the multivariate models that best predicted the occurrence of debris flows were identified. Percentage of high burn severity and 3-hour peak rainfall intensity were significant variables in all models. Soil organic matter content and soil clay content were significant variables in all models except Model 5. Soil slope was a significant variable in all models except Model 4. The most suitable model can be selected from these five models on the basis of the availability of independent variables in the particular area of interest and field checking of probability maps. The multivariate logistic regression models can be entered into a geographic information system, and maps showing the probability of debris flows can be constructed in recently burned areas of

    Full Text Available Background: Despite the large number of studies on various aspects and forms of supply chain collaboration, the issue is still classified as a relatively poorly recognized research problem in the logistics field. This article is crucial in the discussion on the further directions for the development of cross-organizational collaboration. The main objective of these studies was to assess the readiness of companies to start and develop vertical and horizontal collaboration within logistics. Methods: The research problem was analysed on the basis of primary and secondary data sources. Primary research was conducted among manufacturing and trade companies as well as logistics service providers. In the statistical description the Mann-Whitney U test and Wilcoxon test were used. It was assumed that the result was statistically significant for p<0.05. Results: The results show a high readiness of the companies surveyed for further vertical integration and two variables had a statistically significant effect on the assessment of the respondents, i.e. the current level of integration and the role the respondents played in the supply chain. As far as horizontal cooperation is concerned, the readiness of the companies surveyed for further integration was slightly above the average level. Compared to vertical collaboration, the difference between the average rating was statistically highly significant. Conclusions: The study indicates the need for the companies surveyed to be involved in logistics collaboration. However, it should be emphasized that the respondents prefer collaboration with companies which do not operate at the same level in the supply chain. As far as horizontal collaboration is concerned, the results can be explained by a number of concerns expressed by the respondents regarding the behavior of potential collaborators. Apparently, in this case, an individual approach with a competitive attitude dominates among the respondents.

Through logistics content in non-logistics subjects, non-logistic personnel should acquire knowledge referring to the support of their decision-making processes in various aspects of their lives and work where combat aspects and factors are predominant. Approach to the adoption of logistics content In the process of adoption of logistics content, a combination of traditional and modern ways of studying should be applied, emphasizing active participation of cadets in the process of learning. Cadets should be motivated to use different sources of knowledge (people, documents, space, time… and they should apply them adequately. They should be helped to learn how to make optimal decisions and to solve typical problems in particular situations, considering logistical aspects of decision-making, to learn the art of gathering and classification of information from different areas and sources, art of selection and analysis of information, to learn how to find possibilities of problem-solving and acting according to their own choice (not insisting on conventional solutions, to connect their own experiences and their education as well as to learn and explore on their own. Institutional framework for enhancing education and training Enhancement of quality of logistics education and training should be incorporated in a long-term concept of development of education and training in the defense system and society, considering the technology of education and training process. There should not be a search for fast, cheap and high quality solutions in education since such solutions do not exist either in theory or practice. Education should not be considered as an expense but as an investment seriously

    A detailed landslide susceptibility map was produced using a logistic regression method with datasets developed for a geographic information system (GIS). Known as one of the most landslide-prone areas in China, the Zhongxian-Shizhu segment in the Three Gorges Reservoir region of China was selected as a suitable case to evaluate the frequency and distribution of landslides. The site covered an area of 260.9 km 2 with a landslide area of 5.3 km 2. Four data domains were used in this study: remote sensing products, thematic maps, geological maps, and topographical maps, all with 25 × 25 m 2 pixels or cells. Statistical relationships for landslide susceptibility were developed using landslide and landslide causative factor databases. We extended the application of logistic regression approaches to use all continuous variables as they are, and the landslide density is used to transform these nominal variables to numeric variable. According to the map, 2.8% of the study area was identified as an area with very high-susceptibility, whereas very low-, low-, medium- and high-susceptibility zones covered 18.2%, 36.2%, 26.7%, and 16.1% of the area, respectively. The quality of susceptibility mapping was validated, and the correct classification percentage and root mean square error (RMSE) values for the validation data were 81.4% and 0.392, respectively.

    Multinomial logistic regression is widely used to model the outcomes of a polytomous response variable, a categorical dependent variable with more than two categories. The model assumes that the conditional mean of the dependent categorical variables is the logistic function of an affine combination of predictor variables. Its procedure gives a number of logistic regression models that make specific comparisons of the response categories. When there are q categories of the response variable, the model consists of q-1 logit equations which are fitted simultaneously. The model is validated by variable selection procedures, tests of regression coefficients, a significant test of the overall model, goodness-of-fit measures, and validation of predicted probabilities using odds ratio. This study used the multinomial logistic regression model to investigate obesity and overweight among primary school students in a rural area on the basis of their demographic profiles, lifestyles and on the diet and food intake. The results indicated that obesity and overweight of students are related to gender, religion, sleep duration, time spent on electronic games, breakfast intake in a week, with whom meals are taken, protein intake, and also, the interaction between breakfast intake in a week with sleep duration, and the interaction between gender and protein intake.

    As urban populations increase so does the amount of food transported to cities worldwide, and innovative agro-urban systems are being developed to integrate agricultural production into buildings; for example, by using roof top greenhouses (RTGs). This paper aims to quantify and compare, through a life cycle assessment, the environmental impact of the current linear supply system with a RTG system by using a case study for the production of tomatoes. The main results indicate that a change from the current linear system to the RTG system could result in a reduction, per kilogram of tomatoes (the functional unit), in the range of 44.4-75.5% for the different impact categories analysed, and savings of up to 73.5% in energy requirements. These savings are associated with re-utilisation of packaging systems (55.4-85.2%), minimisation of transport requirements (7.6-15.6%) and reduction of the loss of product during transportation and retail stages (7.3-37%). The RTG may become a strategic factor in the design of low-carbon cities in Mediterranean areas. Short-term implementation in the city of Barcelona could result in savings of 66.1 tonnes of CO₂ eq. ha(-1) when considering the global warming potential, and of 71.03 t ha(-1) when considering that the transformation from woodland to agricultural land is avoided.

    2010-05-01

    This paper presents the results of the cross-validation of a multivariate logistic regression model using remote sensing data and GIS for landslide hazard analysis on the Penang, Cameron, and Selangor areas in Malaysia. Landslide locations in the study areas were identified by interpreting aerial photographs and satellite images, supported by field surveys. SPOT 5 and Landsat TM satellite imagery were used to map landcover and vegetation index, respectively. Maps of topography, soil type, lineaments and land cover were constructed from the spatial datasets. Ten factors which influence landslide occurrence, i.e., slope, aspect, curvature, distance from drainage, lithology, distance from lineaments, soil type, landcover, rainfall precipitation, and normalized difference vegetation index (ndvi), were extracted from the spatial database and the logistic regression coefficient of each factor was computed. Then the landslide hazard was analysed using the multivariate logistic regression coefficients derived not only from the data for the respective area but also using the logistic regression coefficients calculated from each of the other two areas (nine hazard maps in all) as a cross-validation of the model. For verification of the model, the results of the analyses were then compared with the field-verified landslide locations. Among the three cases of the application of logistic regression coefficient in the same study area, the case of Selangor based on the Selangor logistic regression coefficients showed the highest accuracy (94%), where as Penang based on the Penang coefficients showed the lowest accuracy (86%). Similarly, among the six cases from the cross application of logistic regression coefficient in other two areas, the case of Selangor based on logistic coefficient of Cameron showed highest (90%) prediction accuracy where as the case of Penang based on the Selangor logistic regression coefficients showed the lowest accuracy (79%). Qualitatively, the cross

    Debris flow is one of the most destructive mass movements. Sometimes regional debris flow susceptibility or hazard assessments can be more difficult than the other mass movements. Determination of debris accumulation zones and debris source areas, which is one of the most crucial stages in debris flow investigations, can be too difficult because of morphological restrictions. The main goal of the present study is to extract debris source areas by logistic regression analyses based on the data from the slopes of the Barla, Besparmak and Kapi Mountains in the SW part of the Taurids Mountain belt of Turkey, where formation of debris material are clearly evident and common. In this study, in order to achieve this goal, extensive field observations to identify the areal extent of debris source areas and debris material, air-photo studies to determine the debris source areas and also desk studies including Geographical Information System (GIS) applications and statistical assessments were performed. To justify the training data used in logistic regression analyses as representative, a random sampling procedure was applied. By using the results of the logistic regression analysis, the debris source area probability map of the region is produced. However, according to the field experiences of the authors, the produced map yielded over-predicted results. The main source of the over-prediction is structural relation between the bedding planes and slope aspects on the basis of the field observations, for the generation of debris, the dip of the bedding planes must be taken into consideration regarding the slope face. In order to eliminate this problem, in this study, an approach has been developed using probability distribution of the aspect values. With the application of structural adjustment, the final adjusted debris source area probability map is obtained for the study area. The field observations revealed that the actual debris source areas in the field coincide with

    Full Text Available As the managerial art and science of coordinating the movement of people, finance and things, logistical operations are central to contemporary capital. Despite its materiality in the form of communications and transport infrastructure, logistics remains an abstract machine for many. This is largely due to the compartmental structure of global supply chains and the invisibility of code. In registering the mediating force of logistics, the essay considers parametric politics as an architecture of intervention for both game design and software development. There are implications here not only for gameplay, but also the invention of method and governance of labour. How, for instance, might game design facilitate the production of a political knowledge of logistics? This becomes a matter to address for labour power vis-à-vis collective research on infrastructure, software and global supply chains.

    Full Text Available The Cat Ba National Park area (Vietnam with its tropical forest is recognized as being part of the world biodiversity conservation by the United Nations Educational, Scientific and Cultural Organization (UNESCO and is a well-known destination for tourists, with around 500,000 travelers per year. This area has been the site for many research projects; however, no project has been carried out for forest fire susceptibility assessment. Thus, protection of the forest including fire prevention is one of the main concerns of the local authorities. This work aims to produce a tropical forest fire susceptibility map for the Cat Ba National Park area, which may be helpful for the local authorities in forest fire protection management. To obtain this purpose, first, historical forest fires and related factors were collected from various sources to construct a GIS database. Then, a forest fire susceptibility model was developed using Kernel logistic regression. The quality of the model was assessed using the Receiver Operating Characteristic (ROC curve, area under the ROC curve (AUC, and five statistical evaluation measures. The usability of the resulting model is further compared with a benchmark model, the support vector machine (SVM. The results show that the Kernel logistic regression model has a high level of performance in both the training and validation dataset, with a prediction capability of 92.2%. Since the Kernel logistic regression model outperforms the benchmark model, we conclude that the proposed model is a promising alternative tool that should also be considered for forest fire susceptibility mapping in other areas. The results of this study are useful for the local authorities in forest planning and management.

    Full Text Available Background: The logistics has its practical input in creating economical strategies as well as in creating modern economic environment. Processes of planning, designing and functioning of logistic systems must be based both on the theoretical knowledge covering various areas as well as practical experiences to provide the required support.  To provide logistic services in the rational way, it is necessary to learn the complicated set of implications resulting from three areas covering the theoretical knowledge, practical ones as well as the regulation by the law. Methods: The triad of three concepts: theory, practice and regulation is the main area of consideration in relation to tasks of the logistic support provided by any organization for any production process. The aim of this paper focuses on the necessity of taking into account implications among theory, practice and regulation during the process of analyzing, designing and implementation of systems of the logistic support. The lack of awareness of differences between various implications or ignoring them must lead to irrational behaviors. Results: The implications among theory, practice and legislative regulation of logistics presented differently than usually, broaden the logistic knowledge and at the same time provide the tool of the rationalization of logistic services in all kinds of activities. Conclusions: The correct identification of tasks and functions of the logistics leads to the recognition of its subject and tasks and correct identification of implications occurring among theory, practice and regulation. This knowledge is indispensable in the process of creation of projects of logistic services of each activity, both business and non-business one.

    Dentofacial morphology may affect orofacial functions, therefore the aim of the current study was to evaluate the influence of craniofacial morphology on masticatory function, occlusal contact area (OCA), and masticatory muscles activity. Seventy-eight (78) subjects were divided into three groups according to vertical facial pattern: 1. mesofacial; 2. brachyfacial; and 3. dolichofacial. Artificial material and the sieving method were used to access masticatory efficiency (ME). OCA was determined by registration of posterior teeth. Electromyographic (EMG) activity of the masseter and anterior temporal (AT) muscles was accessed bilaterally at rest and at maximal vertical clenching (MVC). ME (%) was significantly higher in brachyfacial and lower in dolichofacial subjects. Brachyfacials presented the highest OCA (mm2) followed by meso and dolichofacial subjects. The EMG of the masseter and AT at rest and at MVC showed that dolichofacial subjects presented the lowest activity values, while brachyfacial subjects presented significantly higher measurements. Craniofacial morphology affected masticatory function, OCA, and EMG activity of the masticatory muscles.

    Marchette, Frances Lenora

    The purpose of this mixed modal study was to compare the results of Biology Subject Area mean scores of students on a 4 x 4 block schedule, A/B block schedule, and traditional year-long schedule for 1A to 5A size schools. This study also reviewed the data to determine if minority or gender issues might influence the test results. Interviews with administrators and teachers were conducted about the type of schedule configuration they use and the influence that the schedule has on student academic performance on the Biology Subject Area Test. Additionally, this research further explored whether schedule configurations allow sufficient time for students to construct knowledge. This study is important to schools, teachers, and administrators because it can assist them in considering the impacts that different types of class schedules have on student performance and if ethnic or gender issues are influencing testing results. This study used the causal-comparative method for the quantitative portion of the study and constant comparative method for the qualitative portion to explore the relationship of school schedules on student academic achievement on the Mississippi Biology Subject Area Test. The aggregate means of selected student scores indicate that the Mississippi Biology Subject Area Test as a measure of student performance reveals no significant difference on student achievement for the three school schedule configurations. The data were adjusted for initial differences of gender, minority, and school size on the three schedule configurations. The results suggest that schools may employ various schedule configurations and expect student performance on the Mississippi Biology Subject Area Test to be unaffected. However, many areas of concern were identified in the interviews that might impact on school learning environments. These concerns relate to effective classroom management, the active involvement of students in learning, the adequacy of teacher education

    2011-07-01

    Full Text Available This paper presents an analysis of subject-specific radio channels in wireless body area networks (WBANs using a simulation tool based on the parallel finite-difference time-domain (FDTD technique. This technique is well suited to model radio propagations around complex, inhomogeneous objects such as the human body. The impacts of different subjects varying in size on on-body, inter-body, and off-body radio channels are studied. The analysis demonstrates that the characteristics of on-body radio channels are subject-specific and are associated with human gender, height, and body mass index. On the other hand, when waves propagate away from the body, such as in the inter-body and off-body cases, the impacts of different subjects on the channel characteristics are found to be negligible.

    In this study, we conducted a subjective evaluation experiment of a dual manipulator, which exhibits different motion characteristics. There are three motion characteristics: two of which are age-related, and the third is a robot motion characteristic and is newly added to these two motions. The motions are evaluated from motion areas and motion velocities. Subjects are elderly and young people, and the impressions of the motions are compared in two of the different age groups by the Semantic Differential (SD) method. The obtained results indicate that there are age differences in the evaluation of three manipulator motion areas. The elderly people show a higher reliability and a higher familiarity in a robot motion area than in the other two motions. The elderly people seem to be more affected by the manipulator motion than the young people. Therefore, a careful consideration is required when planning the motion of a manipulator for elderly people.

    Nowadays, environmental management becomes a critical business consideration for companies to survive from many regulations and tough business requirements. Most of world-leading companies are now aware that environment friendly technology and management are critical to the sustainable growth of the company. The environment market has seen continuous growth marking 532B in 2000, and 590B in 2004. This growth rate is expected to grow to 700B in 2010. It is not hard to see the environment-friendly efforts in almost all aspects of business operations. Such trends can be easily found in logistics area. Green logistics aims to make environmental friendly decisions throughout a product lifecycle. Therefore for the success of green logistics, it is critical to have real time tracking capability on the product throughout the product lifecycle and smart solution service architecture. In this chapter, we introduce an RFID based green logistics solution and service.

    Full Text Available Craniofacial dimensions influence oral functions; however, it is not known whether they are associated with function asymmetry. The objective of this study was to evaluate chewing side preference and lateral asymmetry of occlusal contact area and bite force of individuals with different craniofacial patterns. Seventy-eight dentate subjects were divided into 3 groups according to the VERT index as follows: (1 mesofacial, (2 brachyfacial and (3 dolichofacial. Chewing side preference was evaluated using jaw tracking equipment, occlusal contact area was measured by silicon registration of posterior teeth, and bite force was measured unilaterally on molar regions using 2.25 mm-thick sensors. Statistical analysis was performed using ANOVA on Ranks, Student's t-test, and Mann-Whitney tests at a 5% significance level. Mesofacial, brachyfacial, and dolichofacial subjects presented more occlusal contact area on the left side. Only dolichofacial subjects showed lateral asymmetry for bite force, presenting higher force on the left side. No statistically significant differences were found for chewing side preference among all groups. Within the limitations of this study, it can be concluded that craniofacial dimensions play a role in asymmetry of bite force. ClinicalTrials.gov ID: NCT01286363.

  10. Biomass Logistics

    Energy Technology Data Exchange (ETDEWEB)

    2015-04-01

    Equipment manufacturers have made rapid improvements in biomass harvesting and handling equipment. These improvements have increased transportation and handling efficiencies due to higher biomass densities and reduced losses. Improvements in grinder efficiencies and capacity have reduced biomass grinding costs. Biomass collection efficiencies (the ratio of biomass collected to the amount available in the field) as high as 75% for crop residues and greater than 90% for perennial energy crops have also been demonstrated. However, as collection rates increase, the fraction of entrained soil in the biomass increases, and high biomass residue removal rates can violate agronomic sustainability limits. Advancements in quantifying multi-factor sustainability limits to increase removal rate as guided by sustainable residue removal plans, and mitigating soil contamination through targeted removal rates based on soil type and residue type/fraction is allowing the use of new high efficiency harvesting equipment and methods. As another consideration, single pass harvesting and other technologies that improve harvesting costs cause biomass storage moisture management challenges, which challenges are further perturbed by annual variability in biomass moisture content. Monitoring, sampling, simulation, and analysis provide basis for moisture, time, and quality relationships in storage, which has allowed the development of moisture tolerant storage systems and best management processes that combine moisture content and time to accommodate baled storage of wet material based upon “shelf-life.” The key to improving biomass supply logistics costs has been developing the associated agronomic sustainability and biomass quality technologies and processes that allow the implementation of equipment engineering solutions.

    -in checkpoints which allow a retrospection of the results of corporate processes, if necessary, a formation or improvement of the processes. The cost and income management includes the most critical points of the operation of enterprises since it can be posited that, despite the dissimilar activities and management of organizations with different profiles, the common interest of every organization is to reach the better results, and with it, the higher profit and indeed to maximize it as well as to reduce or minimize the costs related to the activities. The simultaneous application of a logistical system approach and controlling even more allows the control, if necessary, a formation and development of the processes. In the life of corporations, these activities are able to appear as a tool increasing the competitiveness, efficiency. Summarizing the above, the reasons of applying the controlling system are the minimal possibility of errors and the opportunity for reaching the maximum profit which are outcomes from the information supplying, leading and coordinating functions of the system. I have carried out an empirical research regarding the following questions. What opinion do the organizations hold on the significance of feedback? How are their activities influenced by the application of a logistics controlling system or the lack of it? Have the organizations experienced an improvement in their economic results thanks to the feedback and the accurate information supply? What areas have been affected by the introduction of a logistics controlling system?

    The aim of this study was to characterize the leading topics in respiratory system in Spain through a bibliometric analysis. For identify and characterize the performance of the different research topics in respiratory system in Spain, we compile the production using a journal that turn out representative of a broad group of researcher. In this sense the journal Archivos de Bronconeumología is the most important publication in Spanish language of this field. A total of 2198 articles published in Archivos Bronconeumología from 1970 to 2000 were analyzed. In each three decades, we did not found differences except in the productivity index in oncology in the eighty decade and in respiratory failure and sleep disturbance (RFSD) and oncology areas in the ninetieth decade and in the Price index (consumption indicators) in the diagnostic and therapeutic techniques area in seventy decade. When we compare the productivity index of each subject areas between decades, we found a significant production increase in the ninetieth decade in asthma, RFSD, tuberculosis, non tuberculosis infection, circulation, oncology, pleural disease and interstitial areas versus the same in seventy decade, and also, we found significant differences between ninetieth and eighty decades in the asthma, RFSD, non tuberculosis infection, circulation and pleural disease areas. Tuberculosis area maintains an insularity index higher than the other areas. We also found a progressive increase in the insularity index of RFSD, non tuberculosis infection, oncology and interstitial disease areas. In general all the indicators maintains stable although the more productivity topics were respiratory failure and sleep disturbances, and oncology. The productivity has increased in asthma, respiratory failure and sleep disturbances, tuberculosis, non - tuberculosis respiratory infections, oncology, pulmonary circulation, pleura and interstitial disease.

    The implementation of diagnosis-related groups (DRGs) sharply increased economic pressure on hospitals. Hence, process optimization was focussed on cost-intensive areas, namely the operation room (OR) departments. Work-flow in the OR is characterized by a mandatory interlocking of the job functions of many different occupational groups and the availability of a variety of different materials. Alternatives for staff assignment optimization have been published in numerous publications dealing with the importance of OR management. In this connection the issue of material logistics in the context of OR management has not been frequently addressed. In order to perform a surgical procedure according to plan, one depends on personnel and on timely availability of the materials needed. Supply of sterilized materials is of utmost importance, because in most hospitals sterilized surgical devices constitute a critical resource. In order to coordinate the OR process with the production flow of sterilized materials, an organizational connection to the OR management makes sense. Hence, in a German university hospital the Department of Hospital Sterile Supplies was integrated into the OR management of the Department of Anesthesiology. This led to a close coordination of work-flow processes, and concomitantly a significant reduction of production costs of sterile supplies could be achieved by direct interaction with the OR. Thus, hospital sterile supplies can reasonably be integrated into an OR management representing a new interesting business area for OR organization.

    A human blood biomonitoring campaign to detect the environmental exposure to metals (Cd, Cu, Cr, Mn, Pb and Zn) in 265 subjects was performed in the South-Western part of Sardinia (an Italian island) that is a particular area with a great history of coal and metal mining (Pb/Zn mainly) activities and large industrial structures (as metallurgy). Subjects living near the industrial plant area had geometric means (GM) of blood Cd (0.79 μg/l), Cu (971 μg/l), Mn (12.2 μg/l), and Pb (55.7 μg/l) significantly higher than controls (Cd, 0.47 μg/l; Cu, 900 μg/l; Mn 9.98 μg/l; Pb, 26.5 μg/l) and than people living nearby the past mining sites. Subjects living next to one dismissed mine were statistically higher in blood Cu (GM, 1,022 μg/l) and Pb (GM, 41.4 μg/l) concentrations than controls. No differences were observed in people living in the different mining sites, and this might be related to the decennial disclosure of mines and the adoption of environmental remediation programmes. Some interindividual variables influenced blood biomonitoring data, as smoke and age for Cd, gender for Cu, age, sex and alcohol for Pb, and age for Zn. Moreover, blood metal levels of the whole population were similar to reference values representative of the Sardinian population and acceptably safe according to currently available health guidelines.

    Short-stature homeobox (SHOX) gene haploinsufficiency may cause skeletal dysplasia including Léri-Weill Dyschondrosteosis (LWD), a clinical entity characterised by the triad of low height, mesomelic disproportion and Madelung's deformity of the wrist. Bone microarchitecture and estimated strength in adult SHOX mutation carriers have not been examined. Twenty-two subjects with a SHOX mutation including 7 males and 15 females with a median age of 38.8 [21.1-52.2] years were recruited from five unrelated families. The control group consisted of 22 healthy subjects matched on age and sex. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Bone geometry, volumetric density, microarchitecture and finite element estimated (FEA) bone strength were measured using high-resolution peripheral quantitative computed tomography (HR-pQCT). A full region of interest (ROI) image analysis and height-matched ROI analyses adjusting for differences in body height between the two groups were performed. Areal BMD and T-scores showed no significant differences between cases and controls. Total radius area was smaller in cases than controls (207 [176-263] vs. 273 [226-298] mm, pRadius cortical bone area (74 ± 20 vs. 58 ± 17 mm(2), p=0.01) and thickness (1.16 ± 0.30 vs. 0.84 ± 0.26 mm, pRadius trabecular bone area (119 [103-192] vs. 202 [168-247] mm(2), pradius and tibia cortical porosity or FEA failure load between groups. A segment of cortical bone defect was identified in the distal radius adjacent to ulna in five unrelated SHOX mutation carriers. Subjects with a SHOX mutation presented with a different bone geometry in radius and tibia while there were no differences in BMD or failure load compared to controls, suggesting that mutations in SHOX gene may have an impact on bone microarchitecture albeit not bone strength.

    In this study, the hair and fingernails of the local people in an intensively cultivated agricultural area in Ubon Ratchathani province, Thailand, were used as biomarkers of exposure to arsenic (As) and heavy metals. The study area has shallow acidic groundwater that is contaminated with As and heavy metals. The local people often consume this shallow groundwater; thus, they are exposed to As and heavy metals. Hair and fingernail samples were collected to characterize the differences between shallow groundwater drinking (SGWD) and tap water drinking (TWD) residents. The concentrations of As and the heavy metals Cd, Pb and Hg were significantly higher in the hair samples from the SGWD group than those from the TWD group, especially for As (0.020-0.571 vs. 0.024-0.359µg/g) and Cd (0.009-0.575 vs. 0.013-0.230µg/g). Similarly, the concentrations of As and the heavy metals in the fingernail samples collected from the SGWD group were larger than those of the TWD group, especially for As (0.039-2.440µg/g vs. 0.049-0.806µg/g). The χ 2 statistic and binary logistic regression were used to find the associated factors and assess the associated probabilities. The regression results show that the factors associated with the concentrations of As and the heavy metals in the hair samples were drinking water source, rate of water consumption, gender, bathing water source, education, smoking and underlying disease, whereas the factors associated with the concentrations of these species in the fingernail samples were drinking water source, gender, occupation, work hours per day, alcohol consumption, and the use of pesticides.

    AIM To evaluate the distribution of refractive error in young subjects in a rural area of Paraguay in the context of an international cooperation campaign for the prevention of blindness. METHODS A sample of 1466 young subjects (ranging from 3 to 22 years old), with a mean age of 11.21±3.63 years old, were examined to assess their distance visual acuity (VA) and refractive error. The first screening examination performed by trained volunteers, included visual acuity testing, autokeratometry and non-cycloplegic autorefraction. Inclusion criteria for a second complete cycloplegic eye examination by an optometrist were VA <20/25 (0.10 logMAR or 0.8 decimal) and/or corneal astigmatism ≥1.50 D. RESULTS An uncorrected distance VA of 0 logMAR (1.0 decimal) was found in 89.2% of children. VA <20/25 and/or corneal astigmatism ≥1.50 D was found in 3.9% of children (n=57), with a prevalence of hyperopia of 5.2% (0.2% of the total) in this specific group. Furthermore, myopia (spherical equivalent ≤-0.5 D) was found in 37.7% of the refracted children (0.5% of the total). The prevalence of refractive astigmatism (cylinder ≤-1.50 D) was 15.8% (0.6% of the total). Visual impairment (VI) (0.05≤VA≤0.3) was found in 12/114 (0.4%) of the refracted eyes. Main causes for VI were refractive error (58%), retinal problems (17%, 2/12), albinism (17%, 2/12) and unknown (8%, 1/12). CONCLUSION A low prevalence of refractive error has been found in this rural area of Paraguay, with higher prevalence of myopia than of hyperopia. PMID:28393041

    When deposited on land the vinasse can promote improvement in fertility, however, often fertilizer application occurs in areas considered homogeneous, without taking into account the variability of the soil. The objective of this study was to evaluate the effect of vinasse application on potassium content in two classes of soils cultivated with sugarcane, and characterize the spatial variability of soil using geostatistical techniques. In the 2010 and 2011 crop year, soil samples were collected from an experimental grid at 0-0.2 and 0.2-0.4 m depth in three soils cultivated with sugarcane, totaling 90 samplings in each grid, for the determination of pH, calcium (Ca), magnesium (Mg), potassium (K), phosphorus (P), aluminum (Al) and potential acidity (H + Al). The data have been submitted to analysis of descriptive statistics and the K attribute was subjected to geostatistical analysis. The coefficient of variation indicated medium and high variability of K for the three soils. The results showed that the spatial dependence of K increased in depth to FRce and decreased to PHlv, indicating that the attribute could have followed the pattern of distribution of clay in depth. The investigation of the spatial variability of K on the surface and subsurface soils provided the definition of management zones with different levels of fertility, which can be organized into sub-areas for a more efficient management of the resources and the environment.

  4. Typology of Logistics Curricula – Four Categories of Logistics of Logistics Undergraduate Education in Europe

    Directory of Open Access Journals (Sweden)

    Tarvo Niine

    2015-05-01

    Full Text Available The field of logistics education is rather colorful. The range of possible topics is huge and so each curriculum has unique approach towards which topic areas to emphasize and which to treat briefly or even omit. There is only little effective standardization in logistics education. This study examines the content of 42 undergraduate logistics curricula in Europe via cluster analysis, with a goal to propose a typology of logistics curricula. The findings define the spectrum of logistics education in four clusters, ranging from „business administration“ with little focus on most specific logistics topics, through „interdisciplinary logistics management“ and „modern transport management“ to „logistics engineering“ with a strong quantitative and technology approach. However, a problem remains that curriculum title does not always reflect actual profile. A typical title “logistics management” might in one case contain various engineering elements, but in another none at all. Such findings point out the need for curricula boards to decide, if trying to cover the entire scope by „one-size-fits-all“ program is the best option or if more distinct focus is needed. In both cases this decision needs to be intentional, agreed and clearly communicated to avoid confusing students and society. Furthermore, the study points out the need to refine standards of competences in logistics, especially for logistics engineering.

    To assess the reproducibility and repeatability of foveal avascular zone (FAZ) area measurements using swept-source optical coherence tomography angiography (SS-OCTA) in healthy subjects. Sixty-four eyes of 64 healthy volunteers were randomly subjected to FAZ area measurements using SS-OCTA by 2 examiners in 2 different sessions. The FAZ areas measured by the first and second observer were 0.269 ± 0.092 mm2 and 0.270 ± 0.090 mm2, respectively. Within subjects, the coefficients of variations were 2.44% (95% confidence interval [CI] 1.95% to 2.93%) and 2.66% (95% CI 2.00% to 3.31%) for the first and second observers, respectively. The coefficient of repeatability average measurements of FAZ area were 0.021 mm2 and 0.024 mm2. The intraclass correlation coefficient values were 0.993 (95% CI 0.989 to 0.996) and 0.991 (95% CI 0.986 to 0.995). Interobserver and intraobserver concordance correlation coefficients ranged from 0.998 (95% CI 0.997 to 0.999) to 0.999 (95% CI 0.998 to 0.999) and from 0.989 (95% CI 0.982 to 0.993) to 0.987 (95% CI 0.979 to 0.992), respectively. The FAZ area measurements by means of SS-OCTA showed high reproducibility and repeatability in healthy eyes.

    Full Text Available Cross-modal activity in visual cortex of blind subjects has been reported during performance of variety of non-visual tasks. A key unanswered question is through which pathways non-visual inputs are funneled to the visual cortex. Here we used tomographic analysis of single trial magnetoencephalography (MEG data recorded from one congenitally blind and two sighted subjects after stimulation of the left and right median nerves at three intensities: below sensory threshold, above sensory threshold and above motor threshold; the last sufficient to produce thumb twitching. We identified reproducible brain responses in the primary somatosensory (S1 and motor (M1 cortices at around 20 ms post-stimulus, which were very similar in sighted and blind subjects. Time-frequency analysis revealed strong 45 to 70 Hz activity at latencies of 20 to 50 ms in S1 and M1, and posterior parietal cortex Brodmann areas (BA 7 and 40, which compared to lower frequencies, were substantially more pronounced in the blind than the sighted subjects. Critically, at frequencies from α-band up to 100 Hz we found clear, strong and widespread responses in the visual cortex of the blind subject, which increased with the intensity of the somatosensory stimuli. Time-delayed mutual information (MI revealed that in blind subject the stimulus information is funneled from the early somatosensory to visual cortex through posterior parietal BA 7 and 40, projecting first to visual areas V5 and V3, and eventually V1. The flow of information through this pathway occured in stages characterized by convergence of activations into specific cortical regions. In sighted subjects, no linked activity was found that led from the somatosensory to the visual cortex through any of the studied brain regions. These results provide the first evidence from MEG that in blind subjects, tactile information is routed from primary somatosensory to occipital cortex via the posterior parietal cortex.

    Modern sign languages used by deaf people are fully expressive, natural human languages that are perceived visually and produced manually. The literature contains little data concerning human brain organization in conditions of deficient sensory information such as deafness. A deaf-mute patient underwent surgery of a left temporoinsular low-grade glioma. The patient underwent awake surgery with intraoperative electrical stimulation mapping, allowing direct study of the cortical and subcortical organization of sign language. We found a similar distribution of language sites to what has been reported in mapping studies of patients with oral language, including 1) speech perception areas inducing anomias and alexias close to the auditory cortex (at the posterior portion of the superior temporal gyrus and supramarginal gyrus); 2) speech production areas inducing speech arrest (anarthria) at the ventral premotor cortex, close to the lip motor area and away from the hand motor area; and 3) subcortical stimulation-induced semantic paraphasias at the inferior fronto-occipital fasciculus at the temporal isthmus. The intraoperative setup for sign language mapping with intraoperative electrical stimulation in deaf-mute patients is similar to the setup described in patients with oral language. To elucidate the type of language errors, a sign language interpreter in close interaction with the neuropsychologist is necessary. Sign language is perceived visually and produced manually; however, this case revealed a cross-modal recruitment of auditory and orofacial motor areas. Copyright © 2017 Elsevier Inc.

    Models and data used to describe species–area relationships confound sampling with ecological process as they fail to acknowledge that estimates of species richness arise due to sampling. This compromises our ability to make ecological inferences from and about species–area relationships. We develop and illustrate hierarchical community models of abundance and frequency to estimate species richness. The models we propose separate sampling from ecological processes by explicitly accounting for the fact that sampled patches are seldom completely covered by sampling plots and that individuals present in the sampling plots are imperfectly detected. We propose a multispecies abundance model in which community assembly is treated as the summation of an ensemble of species-level Poisson processes and estimate patch-level species richness as a derived parameter. We use sampling process models appropriate for specific survey methods. We propose a multispecies frequency model that treats the number of plots in which a species occurs as a binomial process. We illustrate these models using data collected in surveys of early-successional bird species and plants in young forest plantation patches. Results indicate that only mature forest plant species deviated from the constant density hypothesis, but the null model suggested that the deviations were too small to alter the form of species–area relationships. Nevertheless, results from simulations clearly show that the aggregate pattern of individual species density–area relationships and occurrence probability–area relationships can alter the form of species–area relationships. The plant community model estimated that only half of the species present in the regional species pool were encountered during the survey. The modeling framework we propose explicitly accounts for sampling processes so that ecological processes can be examined free of sampling artefacts. Our modeling approach is extensible and could be applied

    2012-05-01

    Full Text Available Within the whole world container traffic, the largest share of containers is in the status of repositioning. Container repositioning results from the need for harmonization between the point of empty container accumulation and the point of demand, and waiting time for the availability of the first next transport of cargo. This status of containers on the container market is the consequence of imbalances in the worldwide trade distribution on most important shipping routes. The need for fast and effective reallocation of empty containers causes high costs and often represents an obstacle affecting the efficiency of port container terminals and inland carriers.In accordance with the above issue, this paper is mainly focused on the analysis of the data concerning global container capacities and the roots of container equipment imbalances, with the aim of determining the importance of empty container management and the need for empty container micro-logistic planning at the spread port area.

  12. Magneto encephalography (MEG: perspectives of speech areas functional mapping in human subjects

    Directory of Open Access Journals (Sweden)

    Butorina A. V.

    2012-06-01

    Full Text Available One of the main problems in clinical practice and academic research is how to localize speech zones in the human brain. Two speech areas (Broca and Wernicke areas that are responsible for language production and for understanding of written and spoken language have been known since the past century. Their location and even hemispheric lateralization have a substantial inter-individual variability, especially in neurosurgery patients. Wada test is one of the most frequently used invasive methodology for speech hemispheric lateralization in neurosurgery patients. However, besides relatively high-risk of Wada test for patient's health, it has its own limitation, e. g. low reliability of Wada-based evidence of verbal memory brain lateralization. Therefore, there is an urgent need for non-invasive, reliable methods of speech zones mapping.The current review summarizes the recent experimental evidence from magnitoencephalographic (MEG research suggesting that speech areas are included in the speech processing within the first 200 ms after the word onset. The electro-magnetic response to deviant word, mismatch negativity wave with latency of 100—200 ms, can be recorded from auditory cortex within the oddball-paradigm. We provide the arguments that basic features of this brain response, such as its automatic, pre-attentive nature, high signal to noise ratio, source localization at superior temporal sulcus, make it a promising vehicle for non-invasive MEG-based speech areas mapping in neurosurgery.

    Deep brain stimulation (DBS) in the pedunculopontine tegmental nucleus (PPTg) has been proposed to alleviate medically intractable gait difficulties associated with Parkinson's disease. Clinical trials have shown somewhat variable outcomes, stemming in part from surgical targeting variability, modulating fiber pathways implicated in side effects, and a general lack of mechanistic understanding of DBS in this brain region. Subject-specific computational models of DBS are a promising tool to investigate the underlying therapy and side effects. In this study, a parkinsonian rhesus macaque was implanted unilaterally with an 8-contact DBS lead in the PPTg region. Fiber tracts adjacent to PPTg, including the oculomotor nerve, central tegmental tract, and superior cerebellar peduncle, were reconstructed from a combination of pre-implant 7T MRI, post-implant CT, and post-mortem histology. These structures were populated with axon models and coupled with a finite element model simulating the voltage distribution in the surrounding neural tissue during stimulation. This study introduces two empirical approaches to evaluate model parameters. First, incremental monopolar cathodic stimulation (20 Hz, 90 μs pulse width) was evaluated for each electrode, during which a right eyelid flutter was observed at the proximal four contacts (−1.0 to −1.4 mA). These current amplitudes followed closely with model predicted activation of the oculomotor nerve when assuming an anisotropic conduction medium. Second, PET imaging was collected OFF-DBS and twice during DBS (two different contacts), which supported the model predicted activation of the central tegmental tract and superior cerebellar peduncle. Together, subject-specific models provide a framework to more precisely predict pathways modulated by DBS. PMID:26236229

    2013-01-01

    Rivers, lakes and the sea were the natural receivers of raw urban waste and storm waters for a long time but the low sustainability of such practice, the increase of population and a renewed environmental sensibility increased researcher interest in the analysis and mitigation of the impact of urban waters on receiving water bodies (RWB). In Europe, the integrated modelling of drainage systems and RWB has been promoted as a promising approach for implementing the Water Framework Directive. A particular interest is given to the fate of pathogens and especially of Escherichia coli, in all the cases in which an interaction between population and the RWB is foreseen. The present paper aims to propose an integrated water quality model involving the analysis of several sewer systems (SS) discharging their polluting overflows on the coast in a sensitive marine environment. From a modelling point of view, the proposed application integrated one-dimensional drainage system models with a complex three-dimensional model analysing the propagation in space and time of E. coli in the coastal marine area. The integrated approach was tested in a real case study (the Acicastello bay in Italy) where data were available both for SS model and for RWB propagation model calibration. The analysis shows a good agreement between the model and monitored data. The integrated model was demonstrated to be a valuable tool for investigating the pollutant propagation and to highlight the most impacted areas.

    Coastal sand dunes are among the most threatened habitats, especially in the Mediterranean Basin, where the high levels of human pressure impair the presence of plant species, putting at risk the maintenance of the ecosystem services, such as CO2 sequestration provided by these habitats. The aim of this study was to analyze how disturbance-induced changes in plant species abundance patterns account for variations in annual CO2 sequestration flow (CS) of Mediterranean sand dune areas. Two sites characterized by a high (site HAD) and a lower (site LAD) anthropogenic disturbance level were selected. At both sites, plant species number, cover, height and CS based on net photosynthesis measurements were sampled. At the plant species level, our results highlighted that Ammophila arenaria and Pancratium maritimum, had a key role in CS. Moreover, the results revealed a patchy species assemblage in both sites. In particular, HAD was characterized by a higher extension of the anthropogenic aphytoic zone (64% of the total transect length) than LAD. In spite of the observed differences in plant species composition, there were not significant differences between HAD and LAD in structural and functional traits, such as plant height and net photosynthesis. As a consequence, HAD and LAD had a similar CS (443 and 421 Mg CO2 ha-1 y-1, respectively). From a monetary point of view, our estimates based on the social costs of carbon revealed that the flow of sequestered CO2 valued on an average 3181 ± 114 ha-1 year-1 (mean value for the two sites). However, considering also the value of the CO2 negative flow related to loss of vegetated area, the annual net benefit arising from CO2 sequestration amounted to 1641 and 1772 for HAD and LAD, respectively. Overall, the results highlighted the importance to maximize the efforts to preserve dune habitats by applying an effective management policy, which could allow maintaining also a regulatory ecosystem service such as CO2 sequestration.

    Subjective well-being (SWB) of older adults could be affected by both individual and community characteristics. However, the effect of community characteristics, such as population aging in local areas, remains unclear. This study examined the cross-sectional and longitudinal associations between the area-level population aging and SWB of older individuals from two distinct surveys. Those analyzed were 572 respondents aged 75 years and older for a cross-sectional survey in a metropolitan area in Tokyo, Japan (Study 1) and 1,257 and 859 respondents for a cross-sectional and longitudinal analysis, respectively, for a 2-year longitudinal survey project in urban and rural areas of Fukui Prefecture (Study 2). Area-level population aging was assessed by the number of people aged 65 years or older per 100 residents. SWB was assessed with the Life Satisfaction Index-A (LSIA). Multilevel analysis was performed to examine unconditional and conditional associations between the area-level number of older adults per 100 residents and the individual-level LSIA scores. The area-level number of older adults per 100 residents was significantly and positively associated with the LSIA scores in Study 1 (p = 0.042), even after controlling for the area- and individual-level covariates. In Study 2, we also found a significant effect of the area-level number of older adults per 100 residents on LSIA scores in the longitudinal multivariate analysis (p = 0.049). Findings from two survey projects suggested cross-validity in the positive effect of area-level population aging on older adults' SWB. Policymakers should consider older citizens' SWB in the recent urban-to-rural migration governmental policy as well as in urban renovation planning.

    Full Text Available The current economic conditions, the rapidity with which the exchange of information, resources and products in the market takes place makes the logistics seem appreciably less significant. However, the importance of logistics has been presented in the military field, through strategies that have led to wining of the great wars that mankind has seen, through the supply of troops with food or moving military equipment. The literature in the field of logistics has numerous works on this topic. But while most focuses on efficient ways of carrying out the component activities of logistics or the strategies of organizations with regard to logistics or its functions, research on dynamics of logistics is underdeveloped. To be able to propose new methods or strategies of logistic activities is necessary to understand the development of this concept, determinant factors and economic and social conditions that gave rise to such developments. Thus, after a presentation of the main landmarks of the historical development of logistics we highlight the importance of the innovation within an organization's value chain innovation, in particular, and how to conduct the business in general. Using generations of innovation identified in the literature, we determine the generation of logistics development, taking into account innovation and how to conduct business. In addition for a better highlight of the own vision over the logistics generations identified, we will present the graphical concept for each generation in part. Last but not least, for each generation identified we try to allocate the chronological landmarks featured in order to reinforce the importance played by innovation in the development of the logistics industry and to give future directions of research within this topic. The study took into account the information presented in articles, books and websites of the relevant specialty in logistics and innovation to be able to build and expose a

    Assessment of synovitis in the metatarsophalangeal (MTP) joints with ultrasound has been shown to improve the accuracy of assessment of rheumatoid arthritis (RA). However, the presence of intraarticular low-echoic synovial area (LESA) in the MTP joints in healthy subjects complicates the sonographic assessment of these joints. Healthy subjects with no arthritic symptoms in their MTP joints were recruited. All subjects completed a questionnaire and underwent physical examination and sonographic assessment. LESAs in the dorsal aspect of all MTP joints were measured in the longitudinal view. One thousand non-arthritic MTP joints in 100 healthy subjects (female 73, mean age 41.0 years old) were evaluated. Measurable LESAs were identified in all joints assessed. Mean length of LESA in each of the 1st-5th MTP joints was 17.8, 13.9, 11.9, 10.6, and 9.2 mm, respectively, whereas mean thickness was 2.4, 2.4, 1.8, 1.2, and 0.8 mm, respectively. Multivariate linear regression models identified the difference between 1st and 5th MTP joints as the most independently influential factor on the measurement of LESA. Our data provide the normal reference values for the measurements of LESA in Japanese, which should be taken into consideration when the synovitis in MTP joints is evaluated with ultrasound.

    To compare optic disc area measurement between optic nerve head drusen (ONHD) and control subjects using fundus photography, time-domain optical coherence tomography (TD-OCT) and spectral-domain optical coherence tomography (SD-OCT). We also made a comparison between each of the three techniques. We performed our study on 66 eyes (66 patients) with ONHD and 70 healthy control subjects (70 controls) with colour ocular fundus photography at 20º (Zeiss FF 450 IR plus), TD-OCT (Stratus OCT) with the Fast Optic Disc protocol and SD-OCT (Cirrus OCT) with the Optic Disc Cube 200 × 200 protocol for measurement of the optic disc area. The measurements were made by two observers and in each measurement a correction of the image magnification factor was performed. Measurement comparison using the Student's t-test/Mann-Whitney U test, the intraclass correlation coefficient, Pearson/Spearman rank correlation coefficient and the Bland-Altman plot was performed in the statistical analysis. Mean and standard deviation (SD) of the optic disc area in ONHD and in controls was 2.38 (0.54) mm(2) and 2.54 (0.42) mm(2), respectively with fundus photography; 2.01 (0.56) mm(2) and 1.66 (0.37) mm(2), respectively with TD-OCT, and 2.03 (0.49) mm(2) and 1.75 (0.38) mm(2), respectively with SD-OCT. In ONHD and controls, repeatability of optic disc area measurement was excellent with fundus photography and optical coherence tomography (TD-OCT and SD-OCT), but with a low degree of agreement between both techniques. Optic disc area measurement is smaller in ONHD compared to healthy subjects with fundus photography, unlike time-domain and spectral-domain optical coherence tomography in which the reverse is true. Both techniques offer good repeatability, but a low degree of correlation and agreement, which means that optic disc area measurement is not interchangeable or comparable between techniques.

    Full Text Available Perception of natural visual scenes activates several functional areas in the human brain, including the Parahippocampal Place Area (PPA, Retrosplenial Complex (RSC, and the Occipital Place Area (OPA. It is currently unclear what specific scene-related features are represented in these areas. Previous studies have suggested that PPA, RSC, and/or OPA might represent at least three qualitatively different classes of features: (1 2D features related to Fourier power; (2 3D spatial features such as the distance to objects in a scene; or (3 abstract features such as the categories of objects in a scene. To determine which of these hypotheses best describes the visual representation in scene-selective areas, we applied voxel-wise modeling (VM to BOLD fMRI responses elicited by a set of 1,386 images of natural scenes. VM provides an efficient method for testing competing hypotheses by comparing predictions of brain activity based on encoding models that instantiate each hypothesis. Here we evaluated three different encoding models that instantiate each of the three hypotheses listed above. We used linear regression to fit each encoding model to the fMRI data recorded from each voxel, and we evaluated each fit model by estimating the amount of variance it predicted in a withheld portion of the data set. We found that voxel-wise models based on Fourier power or the subjective distance to objects in each scene predicted much of the variance predicted by a model based on object categories. Furthermore, the response variance explained by these three models is largely shared, and the individual models explain little unique variance in responses. Based on an evaluation of previous studies and the data we present here, we conclude that there is currently no good basis to favor any one of the three alternative hypotheses about visual representation in scene-selective areas. We offer suggestions for further studies that may help resolve this issue.

    Rehabilitative Ultrasound Imaging (RUSI) must be valuable method for research and rehabilitation. So, the reliability of its measurements must be determined. The purpose of this study was to evaluate the intra-rater reliability of RUSI for measurement of multifidus (MF) muscles cross section areas (CSAs), bladder wall diameter, and thickness of MF muscles between 2 sessions in healthy subjects. Fifteen healthy subjects through simple non-probability sampling participated in this single-group repeated-measures reliability study. MF muscles thickness at rest and during contraction, MF muscles CSAs at rest, and bladder diameters at rest and during pelvic floor muscles (PFM) contraction were measured through RUSI. Pearson's correlation coefficient test was used to determine intra-rater reliability of variables. The results showed that intra-class correlation Coefficient (ICCs) values with 95% confidence interval (CI) and the standard error of the measurement (SEM) were good to excellent agreement for a single investigator between measurement occasions. The intra-rater reliability for the bladder wall displacement was high (ICCs for rest and PFM contraction state: 0.96 and 0.95 respectively), for the MF muscles CSAs at the L4 level was good to high (ICCs 0.75 and 0.91 for right (Rt) and left (Lt) side respectively), and for the thickness of MF muscles at two levels, at rest and during two tasks was moderate to high (ICCs: 0.64 to 0.87). The Trans-Abdominal (TA) method of RUSI is a reliable method to quantify the PFM contraction in healthy subjects. Also, the RUSI is a reliable method to measure the MF muscles CSAs, the MF muscles thickness at rest and during functional tasks in healthy subjects.

    Innovative commercial logistics is required for supporting lunar resource recovery operations and assisting larger consortiums in lunar mining, base operations, camp consumables and the future commercial sales of propellant over the next 50 years. To assist in lowering overall development costs, ``reuse'' innovation is suggested in reusing modified LTS in-space hardware for use on the moon's surface, developing product lines for recovered gases, regolith construction materials, surface logistics services, and other services as they evolve, (Kistler, Citron and Taylor, 2005) Surface logistics architecture is designed to have sustainable growth over 50 years, financed by private sector partners and capable of cargo transportation in both directions in support of lunar development and resource recovery development. The author's perspective on the importance of logistics is based on five years experience at remote sites on Earth, where remote base supply chain logistics didn't always work, (Taylor, 1975a). The planning and control of the flow of goods and materials to and from the moon's surface may be the most complicated logistics challenges yet to be attempted. Affordability is tied to the innovation and ingenuity used to keep the transportation and surface operations costs as low as practical. Eleven innovations are proposed and discussed by an entrepreneurial commercial space startup team that has had success in introducing commercial space innovation and reducing the cost of space operations in the past. This logistics architecture offers NASA and other exploring nations a commercial alternative for non-essential cargo. Five transportation technologies and eleven surface innovations create the logistics transportation system discussed.

    Full Text Available One new concept emerging in current business reality is a virtual supply chain. This paper indicates in what way a virtual supply chain, that is subject to constant changes, influences the requirements for competencies of managerial staff in that specific business environment operating with discontinuities, temporary character, focus on customers, geographical dispersion, intensive support of IT systems, network structure and an extensive use of key competencies of their members. The paper presents the concept of virtual supply chain and results of research conducted in order to determine how current knowledge and skills of decision-makers fit into that concept. In that sense the quality of human resources, connected to logistics operations and management, has been examined from the point of view of the directions of required changes in the area of adequate qualifications and competencies for efficient management of virtual supply chains. Research was be based on a survey, conducted in 2010 and aiming at identification of skills and qualifications of logistics personnel in average Polish companies. Results of the study indicated that logistics qualifications of managerial personnel in Polish companies are constantly improving. Requirements of virtualisation of logistics and supply chain business result in a modified patterns of logistics professional carriers and new challenges for education and training systems.

    The area (A) under the receiver operating characteristic curve is commonly used to quantify the ability of a biomarker to correctly classify individuals into two populations. However, many markers are subject to measurement error, which must be accounted for to prevent understating their effectiveness. In this paper, we develop a new confidence interval procedure for A which is adjusted for measurement error using either external or internal replicated measurements. Based on the observation that A is a function of normal means and variances, we develop the procedure by recovering variance estimates needed from confidence limits for normal means and variances. Simulation results show that the procedure performs better than the previous ones based on the delta-method in terms of coverage percentage, balance of tail errors and interval width. Two examples are presented. Copyright © 2010 John Wiley & Sons, Ltd.

    This exploratory phenomenological case study investigated the influence the full integration of the arts into core subject instruction has on classroom environment, student academic achievement, and student engagement as perceived by administrators, teachers, and students in one East Texas secondary school. Participant interviews were analyzed using Creswell's (2012) six-step method for analyzing phenomenological studies. The researcher implemented three learning activities in which ceramics learning objectives were fully integrated with chemistry learning objectives. The first activity combined clay properties and pottery wheel throwing with significant numbers. The second activity combined glaze formulation with moles. The third combined stoichiometry with the increased glaze formula for students to glaze the bowls they made. Findings suggest the full integration of art in core subject area instruction has numerous positive effects. Participants reported improved academic achievement for all students including reluctant learners. Students, teachers, and the administrator reported greater participation in the art integrated activities. Participants perceived a need for further training for teachers and administrators for greater success.

  19. The response of teachers to new subject areas in a national science curriculum: The case of the earth science component

    Science.gov (United States)

    King, Chris

    2001-11-01

    The National Curriculum for Science (NCS) introduced to schools in England and Wales in 1989 contained an earth science component that was new to many secondary science teachers. Ten years after this introduction, a survey was undertaken to test teacher perception of the effectiveness of their teaching in this subject area that was new to them, and to identify factors that might affect this effectiveness. The information gained has been used in reviewing possible curriculum changes and in developing professional development strategies that would improve the effectiveness of NCS earth science teaching. The data collected from science teachers who are currently teaching this earth science component revealed that their background knowledge of earth science from their own education was generally poor, even though most of them considered their knowledge to be moderate. The teachers indicated that the achievement of their pupils in earth science is moderate, while reports on national testing show it is poor. They reported that their main sources of earth science knowledge and understanding were science textbooks written for 11- to 16-year-old pupils (with their small earth science content of variable quality) and science colleagues (who often have poor earth science backgrounds too). Most teachers indicated that they needed more support in this area. Overall, the data indicated that while teachers consider their teaching in this area to be moderate, other evidence suggests it is poor. If this situation is not to continue it should be addressed. In the longer term the emphasis on the earth science content of the National Science Curriculum could be changed (either enhanced or reduced) within larger scale curriculum changes. Until such curriculum change takes place, effective methods of professional development should be instituted so that teachers have a much improved basis on which to build their earth science teaching. Similar measures would be necessary in other

    The past application of nuclear technology has brought about free emission of numerous Due to the military application of the depleted uranium (DU) in our country, the problem of its radioactivity and hemo toxicity if actualized. Likewise every heavy metal, its is highly toxic and, in addition to it, also radioactive: Interaction of the water-soluble uranium forms with soil is an important effect. In this way, it penetrates into food chain and endangers human health. The study was aimed at determining possible karyotype genotoxic effects in individuals from the regions close to the contaminated areas. Biological dosimetry was performed using modified Moorthead's micromethod. Our studies included the targeted group of 29 patients from the affected regions. The subjects were averagely aged 39.5{+-}2.8 years. Average age of the control group (k), unexposed to the effects of the known genotoxic agents comprising 22 individuals was 28.3{+-}1.2 years. The presented data evidenced that increased incidence of the chromosomal aberrations was found in 6 subjects,accounting for 20.6%. Dicentric type changes were evidence, as well ring chromosomes and eccentric fragments, which are, at the same time the most frequent aberrations. The changes are considered reparable aberrations accounting for 2-3% in metaphases of the unexposed individuals. Statistical data processing evidenced significant difference (p<0.005) between structural chromosomal aberrations in the studied and control groups, as well as in the number of chromatid aberrations (p<0.05).Based on the obtained data it may be concluded that human karyotype changes were present in the studied group, resulting from interaction of ionizing irradiation and other genotoxic agents, with possibility of potent synergistic effects. It is necessary to stress the importance of further monitoring and control of the general population health, particularly due to possible late genetic effects that may affect future generations

    The study's overall objective was to investigate the relationship between psychosocial stressors, sense of community, and subjective wellbeing in urban and rural schoolchildren in Northeast Brazil, focusing on differences according to territorial context. The sample consisted of 757 participants, 495 from urban schools and 262 from rural schools, enrolled in the 6th and 7th grades (9 to 18 years of age) in 21 municipal and state public schools, of which 13 urban and 8 rural, in 7 municipalities (counties) in Ceará State, Brazil. The study instruments were inventory of stressful events, scale of life satisfaction for students, index of sense of community, and satisfaction indices by life domains (family, material goods, relations, neighborhood/zone, health, time, school, and personal). The results indicate that socioeconomically underprivileged public schoolchildren from urban areas are more exposed to daily stress and score lower on satisfaction in specific domains of life and on sense of community. This latter is an important indicator for evaluating wellbeing in this young population.

  16. [Understanding logistic regression].

    Science.gov (United States)

    El Sanharawi, M; Naudet, F

    2013-10-01

    Logistic regression is one of the most common multivariate analysis models utilized in epidemiology. It allows the measurement of the association between the occurrence of an event (qualitative dependent variable) and factors susceptible to influence it (explicative variables). The choice of explicative variables that should be included in the logistic regression model is based on prior knowledge of the disease physiopathology and the statistical association between the variable and the event, as measured by the odds ratio. The main steps for the procedure, the conditions of application, and the essential tools for its interpretation are discussed concisely. We also discuss the importance of the choice of variables that must be included and retained in the regression model in order to avoid the omission of important confounding factors. Finally, by way of illustration, we provide an example from the literature, which should help the reader test his or her knowledge. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    2011-11-01

    Full Text Available As organisations find themselves in an increasingly dynamic and competitive world they are seeking new strategies to ensure their competitive advantage and profitability. Logistics presents an area in which these organisations can improve customer service and reduce costs, and strategies in support thereof such as the outsourcing of logistics activities, should be considered. However, it is critical that logistics outsourcing is done diligently to avoid potential problems for the organisation and to achieve the best possible benefits. In South Africa little research has been done regarding current outsourcing practices of local manufacturers. In this article literature on international logistics outsourcing as well as research on some of the logistics outsourcing practices of South African manufacturers is discussed. The findings of a questionnaire survey of South African manufacturers provided information on their logistics outsourcing practices and problems. Prominent issues seem to include inadequate managerial involvement in the logistics outsourcing process, as well as insufficient time spent on many of the important aspects of the outsourcing agreement, the transitioning of resources and ongoing management of the outsourced relationship. It is concluded that a thorough outsourcing process should be followed in order to achieve the benefits of logistics outsourcing.

    Full Text Available Industry and academia still have a major problem in grasping the extent and relationships ofall functions involved in integrated logistics. This is because business logistics and logistics engineering developed separately, each with their own following, resulting in the two so-called different -disciplines ignoring each other.

    By analysing the definition of integrated logistic support, it is possible to identify the necessary conditions for an integrated logistics model. From these necessary conditions, a model of the management functions and technical activities is constructed to suggest the purpose and place of all logistics functions to work in an integrated way towards the goal of the organisation. The model suggests that logistics engineering and business logistics are both required in the organisation and that it is of vital importance that these functions are executed in unison . This model is different to previous models in that it approaches logistics from the organisations viewpoint rather than from a logistics viewpoint.

  13. The emergence of logistics cities: Conceptual model

    Directory of Open Access Journals (Sweden)

    C. Sengpiehl

    2008-11-01

    Full Text Available This paper describes the emergence of logistics cities, which are geographical concentrations of related industries situated around one or more international trade gateways adjacent to a metropolitan area. Broadly, a logistics city comprises logistics activities and related assets combined with an integrated mix of manufacturing and assembly companies, business services, retail outlets, research and education centres, and associated government services and administration sections. This concept is currently being promoted and developed globally by several regions, and examples of these logistics cities are described in this paper. Drawing from these examples and the limited available literature, a preliminary conceptual map of the logistics cities concept has been developed which incorporates a theoretical foundation of economic development and the principles of competitiveness in the notion of trade clusters. This map has provided the basis for our further investigations and the continued development of a more detailed conceptual model that will provide a systematic knowledge base for those engaged in the development of further logistics cities. The beneficiaries of this model will be public authorities, property developers and industrial concerns, and will be used when making decisions for future logistics infrastructure, services, supporting services and related social elements.

  3. An allometric scaling relation based on logistic growth of cities

    CERN Document Server

    Chen, Yanguang

    2013-01-01

    The relationships between urban area and population size have been empirically demonstrated to follow the scaling law of allometric growth. This allometric scaling is based on exponential growth of city size and can be termed "exponential allometry", which is associated with the concepts of fractals. However, both city population and urban area comply with the course of logistic growth rather than exponential growth. In this paper, I will present a new allometric scaling based on logistic growth to solve the abovementioned problem. The logistic growth is a process of replacement dynamics. Defining a pair of replacement quotients as new measurements, which are functions of urban area and population, we can derive an allometric scaling relation from the logistic processes of urban growth, which can be termed "logistic allometry". The exponential allometric relation between urban area and population is the approximate expression of the logistic allometric equation when the city size is not large enough. The prop...

    To assess the prevalence of left ventricular hypertrophy according to electrocardiographic and echocardiographic criteria among hypertensive patients living in semi-rural Senegalese area. According to the World Health Organization STEPSwise approach, we conducted, in November 2012, a cross-sectional and exhaustive study in the population aged at least 35 years old and living for at least six months in the semi-rural area of Guéoul. We researched electrocardiographic and echocardiographic left ventricular hypertrophy in hypertensive subjects. Data were analyzed with SPSS 18.0 software version. The significance level was agreed for a value of P<0.05. We examined 1411 subjects aged on average of 48.5±12.7 years. In total, 654 subjects were hypertensive and screening of left ventricular hypertrophy (LVH) was effective in 515 of them. According to Sokolow-Lyon index, 86 subjects (16.7%) presented electrocardiographic LVH, more frequently in men (P=0.002). According to Cornell index and Cornell product, LVH was founded respectively in 66 (12.8%) and 52 subjects (10.1%), more frequently in female (P=0.0001; P=0.004). It was more common in grade 3 of hypertension however criteria. In echocardiography, prevalence of LVH was 2.2% (13 cases) according to the left ventricular mass, 9.3% (48 cases) according to the left ventricular mass indexed to body surface area and 8.2% (42 cases) according to the left ventricular mass indexed to height 2.7 . LVH was significantly correlated with the electrocardiographic LVH according to Sokolow-Lyon index (P<0.0001) and the grade 3 of hypertension (P=0.003). Although rare in hypertensive Senegalese living in semi-rural area, left ventricular hypertrophy is correlated with severity of grade of hypertension. Screening by electrocardiogram will allow better follow-up of these hypertensive subjects. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    2006-01-01

    As NASA has embarked on a new Vision for Space Exploration, there is new energy and focus around the area of manned space exploration. These activities encompass the design of new vehicles such as the Crew Exploration Vehicle (CEV) and Crew Launch Vehicle (CLV) and the identification of commercial opportunities for space transportation services, as well as continued operations of the Space Shuttle and the International Space Station. Reaching the Moon and eventually Mars with a mix of both robotic and human explorers for short term missions is a formidable challenge in itself. How to achieve this in a safe, efficient and long-term sustainable way is yet another question. The challenge is not only one of vehicle design, launch, and operations but also one of space logistics. Oftentimes, logistical issues are not given enough consideration upfront, in relation to the large share of operating budgets they consume. In this context, a group of 54 experts in space logistics met for a two-day workshop to discuss the following key questions: 1. What is the current state-of the art in space logistics, in terms of architectures, concepts, technologies as well as enabling processes? 2. What are the main challenges for space logistics for future human exploration of the Moon and Mars, at the intersection of engineering and space operations? 3. What lessons can be drawn from past successes and failures in human space flight logistics? 4. What lessons and connections do we see from terrestrial analogies as well as activities in other areas, such as U.S. military logistics? 5. What key advances are required to enable long-term success in the context of a future interplanetary supply chain? These proceedings summarize the outcomes of the workshop, reference particular presentations, panels and breakout sessions, and record specific observations that should help guide future efforts.

    Reverse logistics in construction refers to the movement of products and materials from salvaged buildings to a new construction site. While there is a plethora of studies looking at various aspects of the reverse logistics chain, there is no systematic review of literature on this important subject as applied to the construction industry. Therefore, the objective of this study is to integrate the fragmented body of knowledge on reverse logistics in construction, with the aim of promoting the concept among industry stakeholders and the wider construction community. Through a qualitative meta-analysis, the study synthesises the findings of previous studies and presents some actions needed by industry stakeholders to promote this concept within the real-life context. First, the trend of research and terminology related with reverse logistics is introduced. Second, it unearths the main advantages and barriers of reverse logistics in construction while providing some suggestions to harness the advantages and mitigate these barriers. Finally, it provides a future research direction based on the review. © The Author(s) 2015.

  18. The perceptions of teachers and principals toward providing additional compensation to teachers in high-need subject areas

    Science.gov (United States)

    Longing, Jeffrey Lucian

    The purpose of this study was to determine possible differences in the perceptions of teachers teaching in high-need areas (i.e., math, science, special education, etc.) and teachers not teaching in high-need areas, (i.e., business education, physical education, etc.) as defined by the states of Arkansas and Louisiana, regarding higher compensation for high-need teachers. In addition, possible perception differences among principals and teachers were determined. The independent variables consisted of gender, position held, years of certified experience, and certification areas. The dependent variable was the perceptions of the participants on providing higher compensation for high-need teachers in order to attract and retain them. The data for all variables were collected using the Teacher Compensation Survey. The sample for this study was limited to teachers, grades 9 through 12, and principals of public high schools in south Arkansas and north Louisiana. Forty-four school districts in south Arkansas (Arkansas Department of Education, 2008a) and north Louisiana (Louisiana Department of Education, 2008a) met the criteria for this study. Twenty-two superintendents gave permission for their districts to participate in the research. A sample of 849 teachers and 38 principals were identified in these districts. Surveys were returned from 350 teachers, creating a 41% response rate. When the 31 principals that returned surveys were added to the total population, the response rate increased to 43% with 381 of the 887 surveyed responding. However, 42 of the teachers and two of the principals skipped some of the questions on the survey and were not included in the study. The researcher used a One-Way ANOVA and independent t-tests to determine the presence of statistical differences at the .05 level. The data showed that most math and science teachers agreed that high-need teachers should be compensated at a higher rate than teachers not teaching in high-need areas. The data

    2013-10-01

    Psoriasis is associated with serious comorbidities such as cardiovascular disease, type 2 diabetes, and metabolic syndrome. These comorbidities are related to low physical activity in the general population. Limited research has evaluated physical activity in psoriasis, and thus, the purpose of this investigation was to compare physical activity between individuals with and without psoriasis as well as explore the associations between measures of psoriasis severity and physical activity. Cross-sectional study using data from the 2003-2006 National Health and Nutrition Examination Survey. Self-reported psoriasis diagnosis and psoriasis severity were regressed on moderate/vigorous physical activity, as measured objectively by accelerometers. Measures of psoriasis severity included rating of psoriasis as a problem in life and body surface area involvement. A total of 4316 individuals had data on psoriasis, moderate/vigorous physical activity, and relevant covariates, with 3.6% (population weighted) of participants (N.=117) reporting a diagnosis of psoriasis. A psoriasis diagnosis was not associated with moderate/vigorous physical activity, and furthermore, body surface area involvement was not associated with moderate/vigorous physical activity among participants with psoriasis. However, every tertile increase in psoriasis as a problem in life was associated with 28% less moderate/vigorous physical activity, which remained significant after adjusting for covariates and removing outliers. While a diagnosis of psoriasis and body surface area involvement do not appear to be associated with less moderate/vigorous physical activity, individuals that rate their psoriasis to be a large problem engage in less moderate/vigorous physical activity.

    Full Text Available In Brazil, malaria is prevalent in the Amazon region and these regions coincide with high prevalence of intestinal parasites but few studies explore the interaction between malaria and other parasites. Therefore, the present study evaluates changes in cytokine, chemokine, C-reactive protein, and nitric oxide (NO concentrations in 264 individuals, comparing plasma from infected individuals with concurrent malaria and intestinal parasites to individuals with either malaria infection alone and uninfected. In the studied population 24% of the individuals were infected with Plasmodium and 18% coinfected with intestinal parasites. Protozoan parasites comprised the bulk of the intestinal parasites infections and subjects infected with intestinal parasites were more likely to have malaria. The use of principal component analysis and cluster analysis associated increased levels of IL-6, TNF-α, IL-10, and CRP and low levels of IL-17A predominantly with individuals with malaria alone and coinfected individuals. In contrast, low levels of almost all inflammatory mediators were associated predominantly with individuals uninfected while increased levels of IL-17A were associated predominantly with individuals with intestinal parasites only. In conclusion, our data suggest that, in our population, the infection with intestinal parasites (mainly protozoan does not modify the pattern of cytokine production in individuals infected with P. falciparum and P. vivax.

    2017-01-01

    These proceedings contain research papers presented at the 5th International Conference on Dynamics in Logistics, held in Bremen, Germany, February 2016. The conference is concerned with dynamic aspects of logistic processes and networks. The spectrum of topics reaches from modeling, planning and control of processes over supply chain management and maritime logistics to innovative technologies and robotic applications for cyber-physical production and logistic systems. The growing dynamic confronts the area of logistics with completely new challenges: it must become possible to describe, identify and analyze the process changes. Moreover, logistic processes and networks must be redevised to be rapidly and flexibly adaptable to continuously changing conditions. The book primarily addresses researchers and practitioners from the field of industrial engineering and logistics, but it may also be beneficial for graduate students.

    2014-05-01

    The use of hierarchical logistic regression for provider profiling has been recommended due to the clustering of patients within hospitals, but has some associated difficulties. We assess changes in hospital outlier status based on standard logistic versus hierarchical logistic modelling of mortality. The study population consisted of all patients admitted to acute, non-specialist hospitals in England between 2007 and 2011 with a primary diagnosis of acute myocardial infarction, acute cerebrovascular disease or fracture of neck of femur or a primary procedure of coronary artery bypass graft or repair of abdominal aortic aneurysm. We compared standardised mortality ratios (SMRs) from non-hierarchical models with SMRs from hierarchical models, without and with shrinkage estimates of the predicted probabilities (Model 1 and Model 2). The SMRs from standard logistic and hierarchical models were highly statistically significantly correlated (r > 0.91, p = 0.01). More outliers were recorded in the standard logistic regression than hierarchical modelling only when using shrinkage estimates (Model 2): 21 hospitals (out of a cumulative number of 565 pairs of hospitals under study) changed from a low outlier and 8 hospitals changed from a high outlier based on the logistic regression to a not-an-outlier based on shrinkage estimates. Both standard logistic and hierarchical modelling have identified nearly the same hospitals as mortality outliers. The choice of methodological approach should, however, also consider whether the modelling aim is judgment or improvement, as shrinkage may be more appropriate for the former than the latter.

    [Purpose] This study investigated whether the toe-spread-out exercise affects the hallux valgus angle, the cross-sectional area of the abductor hallucis muscle, and the hallux valgus angle during active abduction. [Subjects and Methods] Twenty-four subjects with hallux valgus were randomly assigned to orthosis and orthosis plus toe-spread-out exercise groups. The orthosis group wore the orthosis for 8 weeks, while the orthosis plus toe-spread-out group also performed the toe-spread-out exercise. The hallux valgus angle, the cross-sectional area of the abductor hallucis muscle, and the hallux valgus angle during active abduction were measured initially and after 8 weeks by radiography and ultrasonography. [Results] While there were no significant changes in the three parameters in the orthosis group, there were significant differences in the orthosis plus toe-spread-out exercise group after 8 weeks. In addition there were significant differences in the three measures between the two groups. [Conclusion] The toe-spread-out exercise reduces the hallux valgus angle and hallux valgus angle during active abduction, and increases the cross-sectional area of the abductor hallucis muscle. The toe-spread-out exercise is recommended for patients with mild to moderate hallux valgus.

    The Ohio Army National Guard (OHARNG) conducts training activities on the lands it manages to fulfill its primary mission of maintaining combat readiness. One of the training areas OHARNG manages is the Ravenna Training and Logistics Site (RTLS). This facility is co-located with the Ravenna Army Ammunition Plant (RVAAP) in Portage and Trumbull Counties, Ohio. Training activities can subject watersheds to various effects. Although environmental effects from training activities cannot be completely avoided, OHARNG is actively seeking for ways to minimize such effects in accordance with Federal, State, and local laws and regulations. This report presents the results of a study by the U.S. Geological Survey (USGS), in cooperation with the OHARNG, to inventory current conditions of the watersheds that drain the RTLS/RVAAP facility. As part of the inventory, a digital geographic database was developed.

  3. An allometric scaling relation based on logistic growth of cities

    Science.gov (United States)

    Chen, Yanguang

    2014-08-01

    The relationships between urban area and population size have been empirically demonstrated to follow the scaling law of allometric growth. This allometric scaling is based on exponential growth of city size and can be termed "exponential allometry", which is associated with the concepts of fractals. However, both city population and urban area comply with the course of logistic growth rather than exponential growth. In this paper, I will present a new allometric scaling based on logistic growth to solve the abovementioned problem. The logistic growth is a process of replacement dynamics. Defining a pair of replacement quotients as new measurements, which are functions of urban area and population, we can derive an allometric scaling relation from the logistic processes of urban growth, which can be termed "logistic allometry". The exponential allometric relation between urban area and population is the approximate expression of the logistic allometric equation when the city size is not large enough. The proper range of the allometric scaling exponent value is reconsidered through the logistic process. Then, a medium-sized city of Henan Province, China, is employed as an example to validate the new allometric relation. The logistic allometry is helpful for further understanding the fractal property and self-organized process of urban evolution in the right perspective.

    2011-12-30

    Logistics, defined as "the time-related positioning of resources" was critical to the implementation of the smallpox eradication strategy of surveillance and containment. Logistical challenges in the smallpox programme included vaccine delivery, supplies, staffing, vehicle maintenance, and financing. Ensuring mobility was essential as health workers had to travel to outbreaks to contain them. Three examples illustrate a range of logistic challenges which required imagination and innovation. Standard price lists were developed to expedite vehicle maintenance and repair in Bihar, India. Innovative staffing ensured an adequate infrastructure for vehicle maintenance in Bangladesh. The use of disaster relief mechanisms in Somalia provided airlifts, vehicles and funding within 27 days of their initiation. In contrast the Expanded Programme on Immunization (EPI) faces more complex logistical challenges. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Previous analyses concerning health components of European Union (EU)-funded research have shown low project participation levels of the 12 newest member states (EU-12). Additionally, there has been a lack of subject-area analysis. In the Health Research for Europe project, we screened all projects of the EU's Framework Programmes for research FP5 and FP6 (1998-2006) to identify health research projects and describe participation by country and subject area. FP5 and FP6 project databases were acquired and screened by coders to identify health-related projects, which were then categorized according to the 47 divisions of the EU Health Portal (N = 2728 projects) plus an extra group of 'basic/biotech' projects (N = 1743). Country participation and coordination rates for projects were also analyzed. Approximately 20% of the 26 946 projects (value €29.2bn) were health-related (N = 4756. Value €6.04bn). Within the health categories, the largest expenditures were cancer (11.9%), 'other' (i.e. not mental health or cardiovascular) non-communicable diseases (9.5%) and food safety (9.4%). One hundred thirty-two countries participated in these projects. Of the 27 EU countries (and five partner countries), north-western and Nordic states acquired more projects per capita. The UK led coordination with > 20% of projects. EU-12 countries were generally under-represented for participation and coordination. Combining our findings with the associated literature, we comment on drivers determining distribution of participation and funds across countries and subject areas. Additionally, we discuss changes needed in the core EU projects database to provide greater transparency, data exploitation and return on investment in health research. © The Author 2013.

    Zhou, Yan Yan; Mi, Jie; Guo, Shengru

    2007-09-01

    In many situations, instead of a complete sample, data are available only in grouped form. For example, grouped failure time data occur in studies in which subjects are monitored periodically to determine whether failure has occurred in the predetermined intervals. Here the model under consideration is the log-logistic distribution. This paper demonstrates the existence and uniqueness of the MLEs of the parameters of the logistic distribution under mild conditions with grouped data. The times with the maximum failure rate and the mode of the p.d.f. of the log-logistic distribution are also estimated based on the MLEs. The methodology is further studied with simulations and exemplified with a data set with artificially introduced grouping from a locomotive life test study.

    The Space Launch System (SLS) is the new NASA heavy lift launch vehicle and is scheduled for its first mission in 2017. The goal of the first mission, which will be uncrewed, is to demonstrate the integrated system performance of the SLS rocket and spacecraft before a crewed flight in 2021. SLS has many of the same logistics challenges as any other large scale program. Common logistics concerns for SLS include integration of discreet programs geographically separated, multiple prime contractors with distinct and different goals, schedule pressures and funding constraints. However, SLS also faces unique challenges. The new program is a confluence of new hardware and heritage, with heritage hardware constituting seventy-five percent of the program. This unique approach to design makes logistics concerns such as commonality especially problematic. Additionally, a very low manifest rate of one flight every four years makes logistics comparatively expensive. That, along with the SLS architecture being developed using a block upgrade evolutionary approach, exacerbates long-range planning for supportability considerations. These common and unique logistics challenges must be clearly identified and tackled to allow SLS to have a successful program. This paper will address the common and unique challenges facing the SLS programs, along with the analysis and decisions the NASA Logistics engineers are making to mitigate the threats posed by each.

    2006-10-01

    The purpose of this study was to identify nicotine dependence, smoking-related attitude, and subjective norms across the stages of change for smoking cessation among adult smokers in a rural area. The subjects were 276 current smokers (male=243, female=33). There were 3 stages of change for smoking cessation: pre-contemplation, contemplation, and preparation stage. Data was collected by an interview or self-reporting from February 12th to March 5th 2004, and analyzed with frequency, percentage, chi- square-test, Fisher's exact probability test, ANOVA, and Scheffe test using the SPSS-PC program. According to the stages of change, 114(41.3%) current smokers were in pre-contemplation, 110(39.9%) in contemplation, and 52(18.8%) in the preparation stage. There was a higher percentage of males than females (chi- square=8.99, p=.011) in the preparation stage. The mean score of the smoking-related attitude (F=7.43, p=.001) and subjective norm(F=27.41, p=.001) were both lowest in the pre-contemplation stage and increased positively during the stages of change for smoking cessation. Based on these findings, the authors recommend that community-based smoking cessation programs should be developed by considering the intention or motives of current smokers and should be initiated in the preparation stage and primarily for male groups.

    recommendations for intellectual thinking, development and operational activities and contributing to the gradual formation of a unified understanding of the logistic system of defense. When considering the directions of the development of logistics services, certain analogy will be applied as in other successful, complex multilevel, organizational and economic systems. The existence of long-term concepts of development, with a built-in organizational aspect, is something that will be asked from competent control and decision-makers. In this paper, certain aspects and segments of the development of the logistics process will be discussed with a high degree of generalization, by relying on authors' experience and research as well as on available sources of knowledge. The aforementioned approach allows for a greater generalalisation of the given views; on the other hand, it can get in strength (the depth and accuracy if validly operationalised in each logistic service, in each particular element or case. Defense as a function of the state Each and every state has an undisputable right on individual and collective defense. Defense is an important state function for the realization of which the government (legislative, executive and judicial is responsible. The defense of the state is the general necessity, right and obligation of all defense and security subjects. No one can be exempt from the efforts necessary for successful defense; therefore, all resources (regardless of property within the state's territory, under certain conditions, become defensive potential and the defense function of the country, according to their nature and needs of the country's defense.

    2016-09-01

    Full Text Available Transporting used household goods (HHGs between different countries involves a great deal of specific processes before and after the actual transportation, which make the industry a specialty of its kind, with its own logistics challenges. Some challenges may look familiar to colleagues of other logistic areas, but most are very particular to this industry. Pronounced seasonal peaks, specific set of skills required, the nature of the goods being transported and the difficult access to them are some of the particular challenges. Tackling them individually is a reasonable task, the problem comes when, as it is the case, the challenges need to be confronted simultaneously. The requirement of specif-ic skilled labor, for example, would not be critical if the business demand was steady throughout the year. Or the other way around, a high variance workload between peak and low seasons would not affect in such way if the job didn’t demand such specific and rare skills. Being one of the less known areas of Logistic Services, it worth having a look into some of the particular characteristics of the International Removals Industry and the challenges they create.

  8. Green Logistics: the Carbon Agenda

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Over the next few decades European companies will come under intense pressure to cut their greenhouse gas (GHG emissions in an effort to achieve very ambitious carbon reduction targets at national, EU and global levels by 2050. This paper presents a framework for the decarbonisation of their logistical activities based on five key freight transport parameters: freight transport intensity, modal split, vehicle utilization, energy efficiency and the carbon intensity of the energy used in logistics. It examines the potential to cut GHG emissions by altering each of these parameters. Consideration is also given to the decarbonisation of warehousing operations. It is concluded that many of the GHG-reduction measures will also yield financial benefit. The decarbonisation of other sectors of the economy may, however, generate greater demand for logistics services.

    In distributed computing environments, performance is often dominated by the time that it takes to move data over a network. In the case of data-centric applications, or Data Grids, this problem of data movement becomes one of the overriding concerns. This talk describes techniques for improving data movement in Grid environments that we refer to as 'logistics.' We demonstrate that by using storage and cooperative forwarding 'in' the network, we can improve end to end throughput in many cases. Our approach offers clear performance benefits for high-bandwidth, high-latency networks. This talk will introduce the Logistical Session Layer (LSL) and provide experimental results from that system.

  11. CONCEPTUAL ISSUES REGARDING REVERSE LOGISTICS

    Directory of Open Access Journals (Sweden)

    Ioana Olariu

    2013-12-01

    Full Text Available As the power of consumers is growing, the product return for customer service and customer retention has become a common practice in the competitive market, which propels the recent practice of reverse logistics in companies. Many firms attracted by the value available in the flow, have proactively participated in handling returned products at the end of their usefulness or from other parts of the product life cycle. Reverse logistics is the flow and management of products, packaging, components and information from the point of consumption to the point of origin. It is a collection of practices similar to those of supply chain management, but in the opposite direction, from downstream to upstream. It involves activities such as reuse, repair, remanufacture, refurbish, reclaim and recycle. For the conventional forward logistics systems, the flow starts upstream as raw materials, later as manufactured parts and components to be assembled and continues downstream to reach customers as final products to be disposed once they reach their economic or useful lives. In reverse logistics, the disposed products are pushed upstream to be repaired, remanufactured, refurbished, and disassembled into components to be reused or as raw material to be recycled for later use.

    The economics of using woody biomass as a fuel or feedstock for bioenergy applications is often driven by logistical considerations. Depending on the source of the woody biomass, the acquisition cost of the material is often quite low, sometimes near zero. However, the cost of harvesting, collection, processing, storage, and transportation from the harvest site to end...

    Kolmykova, Liudmila; Korobova, Elena

    2017-04-01

    Iodine is an essential microelement required for normal functioning of thyroid gland. Natural deficiency of stable iodine is compensated by its active intake by thyroid and provokes its higher irradiation in case of radiation accidents and contamination of the environment by radioiodine isotopes. The bioavailability of both stable and radioactive iodine and the specificity of its uptake by living organisms largely depends on geochemical parameters of the environment related to natural conditions of water migration. The goal of the study was to investigate spatial distribution of iodine in natural water of different chemical composition in relation to typical water-bearing soils and rocks and water fractions in Bryansk areas subjected to radioiodine contamination after the Chernobyl accident and to evaluate contribution of this factor to the occurrence of endemic thyroid diseases among local population inhabiting geochemically different areas of fluvioglacial and loess-like sedimentary rocks. The highest content of iodine (Me=13.3 µg/l) was observed in surface water of landscapes with H-Ca, Ca and H-Ca-Fe classes of water migration. The lowest microelement level (Me=5.25 µg/l) was noted in groundwater of landscapes with H, H-Fe classes of water migration in areas of Paleogene water bearing rocks. Regardless of the type of source and class of water migration up to 90% of the total content of iodide is present in the fraction membrane filtration). Up to 50% of iodine pass to solution containing particles water in areas of loess-like sedimentary rocks hosts the highest levels of iodine where its associated with calcium mineral aquatic complexes and the suspended particles. The obtained data is believed to be useful in explanation of mobility and intake of iodine and its radioactive analogues by rural population living in different geochemical conditions and using local drinking waters. The data should be accounted of in planning prophylactics of endemic diseases and

    Full Text Available Programmes of formal education establish a systematic transfer of knowledge as well as universal values from one generation to another. By that, they ensure the survival of social structures, prevent radical disruptions in their continuity, and serve as basis for general development of a society. Their content and didactic arrangements include interweaving of two basic aspects: the cognitive one and the one related to vzgoja (i.e. upbringing, moral/value education etc.. The latter aims to achieve the ideals of a tolerant, just and lifelong learning society, but seems to be facing increasing challenges, mainly emerging from neoliberal capitalist mentality. Art history as a school subject area in elementary and secondary education may provide an insight beneath the surface of historical events. Thus, it helps develop a critical view towards them and consequently towards the present real-life situations, which contributes to ascending the taxonomic scale of conative educational goals.

  5. WHY DO LOGISTICS AND TRANSPORT MATTER FOR DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    Nedelescu-Ionescu Daniela

    2014-07-01

    Full Text Available In face of the challenges of global competition, business firms are concentrating more on the needs of customers and seeking ways to reduce costs, improve quality and meet the ever-rising expectation of their customers. To these ends, many of them have identified logistics as an area to build cost and service advantages. Logistical activities have always been vital to organizations, and therefore business logistics and supply chain management represents a synthesis of many concepts, principles, and methods from the more traditional areas of production, purchasing, transportation, economics, as well as from the disciplines of applied mathematics, and organizational behaviour. It concentrates on important activities of management such as planning, organizing, and controlling, and also on a three-way relationship of related transportation, inventory, and location strategies, which are at the heart of good logistics planning and decision making. Selecting a good logistics strategy may yield a competitive advantage. Transportation provides the flow of materials, products and persons between production facilities, warehouses, distribution centers, terminals and customer locations. The progress in techniques and management principles improves the moving load, delivery speed, service quality, operation costs, the usage of facilities and energy saving. A strong system needs a clear frame of logistics and a proper transport implements and techniques to link the producing procedures. The transportation takes a crucial part in the management of logistic. Without well-developed transportation systems, logistics could not bring its advantages into full play. A good transport system in logistics activities could provide better logistics efficiency, reduce operation cost, and promote service quality. The process determines the efficiency of moving products and energy saving. Improvements in transportation and logistics make valuable contribution to production

    Medical and nursing shortages in rural areas represent a current serious public health problem. The healthcare of the rural population is at risk. This study compares perceived workload, job satisfaction and work-life balance of physicians and nurses at a clinic in a rural area with two clinics of a University hospital. Physicians and nurses were interviewed anonymously with a standardized questionnaire (paper and pencil), including questions on job satisfaction, subjective workload and work-life balance. The response rate was almost 50% in the University hospital as well as in the municipal hospital. 32 physicians and 54 nurses from the University hospital and 18 physicians and 137 nurses from the municipal hospital participated in the survey. Nurses at the University hospital assessed the organization of the daily routine with 94.1% as better than those at the municipal hospital (82.4%, p=0.03). Physicians at the University hospital were able to better implement acquired knowledge at a University clinic with 87.5% than their counterparts at the municipal hospital (55.5%, p=0.02). In contrast to their colleagues at the municipal hospital, only 50% of the physicians at the University hospital subjectively considered their workload as just right (83.3% municipal, p=0.02). 96.9% of the physicians at the University hospital were "daily" or "several times a week" under time pressure (municipal 50%, pwork and family life (62.9% University hospital, 72.8% Municipal hospital). In contrast, only 20% of the physicians at the University Hospital but 42.9% of the physicians of the municipal hospital had sufficient opportunities to balance workload and family (p=0.13). The return rate of almost 50% can be described as good. Due to the small number of physicians, especially from the municipal hospital, it can be assumed that some interesting differences could not be detected. There were only slight differences between the nurses from the two hospitals. In contrast, subjective

  13. Multisource information fusion for logistics

    Woodley, Robert; Petrov, Plamen; Noll, Warren

    2011-05-01

    Current Army logistical systems and databases contain massive amounts of data that need an effective method to extract actionable information. The databases do not contain root cause and case-based analysis needed to diagnose or predict breakdowns. A system is needed to find data from as many sources as possible, process it in an integrated fashion, and disseminate information products on the readiness of the fleet vehicles. 21st Century Systems, Inc. introduces the Agent- Enabled Logistics Enterprise Intelligence System (AELEIS) tool, designed to assist logistics analysts with assessing the availability and prognostics of assets in the logistics pipeline. AELEIS extracts data from multiple, heterogeneous data sets. This data is then aggregated and mined for data trends. Finally, data reasoning tools and prognostics tools evaluate the data for relevance and potential issues. Multiple types of data mining tools may be employed to extract the data and an information reasoning capability determines what tools are needed to apply them to extract information. This can be visualized as a push-pull system where data trends fire a reasoning engine to search for corroborating evidence and then integrate the data into actionable information. The architecture decides on what reasoning engine to use (i.e., it may start with a rule-based method, but, if needed, go to condition based reasoning, and even a model-based reasoning engine for certain types of equipment). Initial results show that AELEIS is able to indicate to the user of potential fault conditions and root-cause information mined from a database.

    Stoltzfus, Jill C

    2011-10-01

    Regression techniques are versatile in their application to medical research because they can measure associations, predict outcomes, and control for confounding variable effects. As one such technique, logistic regression is an efficient and powerful way to analyze the effect of a group of independent variables on a binary outcome by quantifying each independent variable's unique contribution. Using components of linear regression reflected in the logit scale, logistic regression iteratively identifies the strongest linear combination of variables with the greatest probability of detecting the observed outcome. Important considerations when conducting logistic regression include selecting independent variables, ensuring that relevant assumptions are met, and choosing an appropriate model building strategy. For independent variable selection, one should be guided by such factors as accepted theory, previous empirical investigations, clinical considerations, and univariate statistical analyses, with acknowledgement of potential confounding variables that should be accounted for. Basic assumptions that must be met for logistic regression include independence of errors, linearity in the logit for continuous variables, absence of multicollinearity, and lack of strongly influential outliers. Additionally, there should be an adequate number of events per independent variable to avoid an overfit model, with commonly recommended minimum "rules of thumb" ranging from 10 to 20 events per covariate. Regarding model building strategies, the three general types are direct/standard, sequential/hierarchical, and stepwise/statistical, with each having a different emphasis and purpose. Before reaching definitive conclusions from the results of any of these methods, one should formally quantify the model's internal validity (i.e., replicability within the same data set) and external validity (i.e., generalizability beyond the current sample). The resulting logistic regression model

    2015-04-01

    Water is one of the main natural agents providing chemical elements' migration in the environment and food chains. In our opinion a study of spatial variation of the essential trace elements in local drinking water is worth considering as the factor that may contribute to variation of the health risk in areas contaminated by radionuclides and radioiodine in particular. Radioiodine was proved to increase the risk of thyroid cancer among children who lived in areas contaminated during the Chernobyl accident. It was also shown that low stable iodine status of the contaminated area and population also contributed to the risk of this disease in case of radionuclide contamination. The goal of the study was to investigate chemical composition of the drinking water in rural settlements of the Bryansk oblast' subjected to radioiodine contamination and to evaluate speciation of stable I and Se on the basis of their total concentration and chemical composition of the real water samples with the help of thermodynamic modelling. Water samples were collected from different aquifers discharging at different depths (dug wells, local private bore holes and water pipes) in rural settlements located in areas with contrasting soil iodine status. Thermodynamic modelling was performed using original software (HCh code of Y.Shvarov, Moscow State University, RUSSIA) incorporating the measured pH, Corg and elements' concentration values. Performed modelling showed possibility of formation of complex CaI+ ion in aqueous phase, I sorption by goethite and transfer of Se to solid phase as FeSe in the observed pH-Eh conditions. It helped to identify environmental conditions providing high I and Se mobility and their depletion from natural waters. Both the experimental data and modeling showed that I and Se migration and deficiency in natural water is closely connected to pH, Eh conditions and the concentration of typomorphic chemical elements (Ca, Mg, Fe) defining the class of water migration

From its original acceptance in epidemiologic research, the method is now commonly employed in almost all branches of knowledge. Rainfall is one of the most important phenomena of climate system. It is well known that the variability and intensity of rainfall act on natural, agricultural, human and even total biological system. So it is essential to be able to predict rainfall by finding out the appropriate predictors. In this paper an attempt has been made to use logistic regression for predicting rainfall. It is evident that the climatic data are often subjected to gross recording errors though this problem often goes unnoticed to the analysts. In this paper we have used very recent screening methods to check and correct the climatic data that we use in our study. We have used fourteen years’ daily rainfall data to formulate our model. Then we use two years’ observed daily rainfall data treating them as future data for the cross validation of our model. Our findings clearly show that if we are able to choose appropriate predictors for rainfall, logistic regression model can predict the rainfall very efficiently.

    Full Text Available The facility allocation problem sets out to determine the optimal number of facilities to be opened. Based on multiple criteria evaluation, the optimal location of the facilities is usually solved subsequently. Several considerations, e.g. technical parameters, costs and finance must be taken into account. Economic analysis is carried out on the basis of the specific instance of the problem.Let us assume that the number of potentially located facilities is known. Then the problem of the optimal location of a given number of facilities in a network is referred to as the facility location problem. The solution to the problem is a set of facilities optimally located in an area such that this area is fully covered by the required services that the facilities provide. An example of a real-life problem of this type is the location of logistics centers.

    As one of the most popular statistical and machine learning models, logistic regression with regularization has found wide adoption in biomedicine, social sciences, information technology, and so on. These domains often involve data of human subjects that are contingent upon strict privacy regulations. Concerns over data privacy make it increasingly difficult to coordinate and conduct large-scale collaborative studies, which typically rely on cross-institution data sharing and joint analysis. Our work here focuses on safeguarding regularized logistic regression, a widely-used statistical model while at the same time has not been investigated from a data security and privacy perspective. We consider a common use scenario of multi-institution collaborative studies, such as in the form of research consortia or networks as widely seen in genetics, epidemiology, social sciences, etc. To make our privacy-enhancing solution practical, we demonstrate a non-conventional and computationally efficient method leveraging distributing computing and strong cryptography to provide comprehensive protection over individual-level and summary data. Extensive empirical evaluations on several studies validate the privacy guarantee, efficiency and scalability of our proposal. We also discuss the practical implications of our solution for large-scale studies and applications from various disciplines, including genetic and biomedical studies, smart grid, network analysis, etc.

We consider a common use scenario of multi-institution collaborative studies, such as in the form of research consortia or networks as widely seen in genetics, epidemiology, social sciences, etc. To make our privacy-enhancing solution practical, we demonstrate a non-conventional and computationally efficient method leveraging distributing computing and strong cryptography to provide comprehensive protection over individual-level and summary data. Extensive empirical evaluations on several studies validate the privacy guarantee, efficiency and scalability of our proposal. We also discuss the practical implications of our solution for large-scale studies and applications from various disciplines, including genetic and biomedical studies, smart grid, network analysis, etc.

    2014-12-01

    Full Text Available Background: Today's business reality requires employees to continuously develop their professional competence and to keep requalifying in the face of structural unemployment risk. The need for staying up to date on ICT technologies brings into focus the competence that logistics trainers and teachers should demonstrate to be able to teach the human resources in demand by the European economy.  Material and methods: A study into the level of competence required to be able to deliver trainings with the use of ICT tools was conducted among experienced practitioners (trainers and teachers from Germany, Italy and Poland. The study had a form of a questionnaire survey made available on the project's website. Electronic data has been subject to a statistical analysis with the application of descriptive statistics tools.  Results: The respondents from all the countries agreed that teachers and trainers should demonstrate ICT competencies at the application level. Some differences in this opinion transpired in the course of a detailed analysis of the levels required for each competency. Conclusions: The results of the survey into which competencies should be given the highest regard differed from country to country. These differences can be attributed to the role of ICT tools in logistics vocational trainings. The respondents from Germany and Poland are focused on the quality of training materials and on their delivery. Italian trainers attach the greatest importance to communication and cooperation with the trainees.

    2013-12-01

    Full Text Available Introduction Changes in social environment require adequate answers of all organizational systems, including defense systems and their logistic systems. Improvement of management in defense logistics involves good knowledge of management theory and practice, knowledge of the impact of ownership and market on management, knowledge of public and other macroeconomic sectors functioning, broader opening towards environment and the exchange of knowledge, information and lessons learned with international environment. The paper presents theoretical and practical knowledge that is prerequisite for improving the management of defense and the management of defense logistic systems.   Definition and the essence of management   Regarding its complexity and a lack of a comprehensive definition, the concept of management is nowadays considered in three ways: as a skill, as social categories - structure of management, as well as a theory - a scientific discipline. When we aanalyze the phenomenon of management, with respect to the historical aspect of its development, there is a necessity to distinguish between management as a scientific discipline and management practice.   Relation between organizational science and management In theory and practice, management is associated with the achievements of many other scientific fields. One of the areas closest to management is organizational science. Today, in the management theory and organization theory, the prevailing attitudes state that these two areas are non-separable and that they are focused on the explaination of the same phenomenon, with the same desire to improve effectivity and development of different purpose systems. There is no clear boundary between organizational science and management, both from theoretical and practical aspects.   Achievements and shortcomings of organizational schools   As a result of solving problems in real systems, a number of opinions and different organizational

    Full Text Available This study aims to identify the main practices of green logistic considered in national and international academic literature. Using standard techniques for selection of previous studies, this study firts presents the definition of green logistic term in order to differentiate it from other concepts commonly treated similarly, as circular economy, the green chain management (GSCM, the reverse logistics and the environmental certifications (ISO 14001, to obtain clarity about their delimitations, scopes and depth. The study also organizes a taxonomy that involves different functional areas of the company, giving direction to the sustainable conduct, resulting in nine components of green logistic that serve as subsidy for the classification of the identified practices. Based on this conceptual definition and taxonomy, lists 112 practices of green logistic, among which 85 are enterprise ambit, 24 governmental and 3 towards consumers. Regarding the quantity of identified practices and the number of citations, both in business sphere as well as in governmental, the most representative part is related to green  Among the most cited practices are the search by more efficient deliveries, using intermodal and multimodal transport that are less polluting and the programming and optimization of flows deliveries. The survey also revealed that although the concept of green logistics is consolidated in the literature, the majority of studies, especially the empirical, concentrates on some of its components, in particular transport and reverse logistic.

    Full Text Available This paper presents the procedure for logistics system scenario selection for the central business district (CBD of the city in the phase of significant urban changes. Scenarios are defined in accordance with the overall logistics concept of the city. Conflicting goals of stakeholders (residents, shippers and receivers, logistics providers and city government generate a vast number of criteria that need to be included when selecting the scenario for the city area logistics system. Due to limited resources and linguistic assessment of criteria, fuzzy extensions of conventional multi-criteria decision-making (MCDM methods were used. Fuzzy "analytical hierarchy process" (FAHP is applied to determine the relative weights of evaluation criteria, and fuzzy "technique for order preference by similarity to ideal solution" (FTOPSIS is applied to rank the logistics systems scenarios. This paper contributes to the literature in the field of city logistics (CL, as it applies the integrated FAHP-FTOPSIS method for the evaluation of scenarios, which are also integrated combinations of different CL initiatives. The integrated combined approach proved to be accurate, effective and a systematic tool for the decision support in the process of selecting CBD logistics scenarios.

    2017-01-01

    We sought to ascertain the changes in mortality from ischaemic heart disease (IHD) from 2004 to 2010 in China as the sheer size of China's population makes disease patterns relevant globally. Data on IHD mortality were obtained from the Chinese Centre for Disease Control and Prevention National Disease Surveillance Point System, which includes 161 counties and a population of over 73 million-a representative sample of over 6% of the entire population of China. Both crude and World Health Organization (WHO)-standardized IHD mortality increased, in both men and women and in both urban and rural locations, during the study period, demonstrating the effect of urbanization, economic growth, and epidemiological transition on cardiovascular health. WHO-standardized IHD mortality increased for rural males by 9.2% per year (95% CI: 6.7-11.7%; P < 0.0001), and the trend was statistically significantly higher (P = 0.0001) than in urban males by 6.4% per year (95% CI: 3-10%; P = 0.02). WHO-standardized IHD mortality rate increased for rural females by 7.0% per year (95% CI: 4.6-9.4%; P < 0.0001); this was statistically significantly higher than urban females by 4.3% per year (95% CI: 1-8%; P = 0.02). The age group over 80 years showed the greatest increase in IHD mortality. Mortality from IHD is increasing in China, in contrast to decreasing in other countries. This is largely driven by increasing IHD mortality in rural areas and subjects over 80 years old. This needs urgent attention by public health workers and policymakers.

    The conception of the field of pharmaceutical service defines pharmaceutical service as the basic part of pharmacy, the principal task of which is to provide pharmaceutical care as an inseparable part of providing health care. It represents a set of professional activities of the pharmacist oriented to securing human and veterinary pharmaceutical products and health care products and to optimising effective, safe and quality pharmacotherapy. Technically, pharmaceutical service is an applied discipline, as it makes use of knowledge gained in other pharmaceutical, medical, psychological, social, and economic sciences. Because of its interdisciplinary character it is necessary to extend the theory of pharmaceutical service in such a way so that it may reflect all aspects of its sphere of activity. One of the possibilities is to define the pharmacy premises as an independent functional unit which operates on the basis of valid legal standards in such a way that on the one hand it secures the provision of health (pharmaceutical) care, and on the other hand it maintains its cost-effectiveness. To keep the quality of care of the patient and the economic aspect in balance, it is necessary to define the term pharmaceutical logistics also under the conditions of Slovak (Czech) pharmacy as early satisfaction of the requirements of the patient (client) in the pharmacy premises, which means that the appropriate pharmaceutical product or health care product and the appropriate information must be at the right time in the required amount and required quality in the right place.

    Feedstock supply system encompasses numerous unit operations necessary to move lignocellulosic feedstock from the place where it is produced (in the field or on the stump) to the start of the conversion process (reactor throat) of the biorefinery. These unit operations, which include collection, storage, preprocessing, handling, and transportation, represent one of the largest technical and logistics challenges to the emerging lignocellulosic biorefining industry. This chapter briefly reviews the methods of estimating the quantities of biomass, followed by harvesting and collection processes based on current practices on handling wet and dry forage materials. Storage and queuing are used to deal with seasonal harvest times, variable yields, and delivery schedules. Preprocessing can be as simple as grinding and formatting the biomass for increased bulk density or improved conversion efficiency, or it can be as complex as improving feedstock quality through fractionation, tissue separation, drying, blending, and densification. Handling and transportation consists of using a variety of transport equipment (truck, train, ship) for moving the biomass from one point to another. The chapter also provides typical cost figures for harvest and processing of biomass.

    The NASA Advanced Exploration Systems (AES) Logistics Reduction and Repurposing (LRR) project strives to enable a largely mission-independent cradle-to-grave-to-cradle approach to minimize logistics contributions to total mission architecture mass. The goals are to engineer logistics materials, common crew consumables, and container configurations to meet the following five basic goals: 1. Minimize intrinsic logistics mass and improve ground logistics flexibility. 2. Allow logistics components to be directly repurposed for on-orbit non-logistics functions (e.g., crew cabin outfitting) thereby indirectly reducing mass/volume. 3. Compact and process logistics that have not been directly repurposed to generate useful on-orbit components and/or compounds (e.g., radiation shielding, propellant, other usable chemical constituents). 4. Enable long-term stable storage and disposal of logistics end products that cannot be reused or repurposed (e.g., compaction for volume reduction, odor control, and maintenance of crew cabin hygienic conditions). 5. Allow vehicles in different mission phases to share logistics resources. This paper addresses the work being done to meet the second goal, the direct repurposing of logistics components to meet other on-orbit needs, through a strategy termed Logistics to Living (L2L). L2L has several areas but can be defined as repurposing or converting logistical items (bags, containers, foam, components, etc.) into useful crew items or life support augmentation on-orbit after they have provided their primary logistics function. The intent is that by repurposing items, dedicated crew items do not have to be launched and overall launch mass is decreased. For non-LEO missions, the vehicle interior volume will be relatively fixed so L2L will enable this volume to be used more effectively through reuse and rearrangement of logistical components. Past work in the area of L2L has already conceptually developed several potential technologies [Howe

    To compare the masticatory and cervical muscle tenderness and pain sensitivity in the hand (remote region) between patients with temporomandibular disorders (TMD) and healthy controls. Twenty female subjects were diagnosed with chronic TMD, and 20 were considered healthy. Subjects completed the Neck Disability Index and Limitations of Daily Functions in a TMD questionnaire. Tenderness of the masticatory and cervical muscles and pain sensitivity in the hand were measured using an algometer. Three-way mixed analysis of variance (ANOVA) evaluated differences in muscle tenderness between groups. One-way ANOVA compared pain sensitivity in the hand between groups. Effect sizes were assessed using Cohen guidelines. Significantly increased masticatory and cervical muscle tenderness and pain sensitivity in the hand were found in subjects with TMD when compared with healthy subjects. Moderate to high effect sizes showed the clinical relevance of the findings. The results of this study have highlighted the importance of assessing TMD patients not only in the craniofacial region but also in the neck and other parts of the body. Future studies should focus on testing the effectiveness of treatments addressing the neck and the pain sensitivity in the hand in patients with TMD.

  5. Reverse logistics for recycling: The customer service

    Directory of Open Access Journals (Sweden)

    Reis, E.

    2009-01-01

    Full Text Available Customer service is a central concern in the logistics practice and a study topic in the forward logistics research. This article investigates the elements of customer service and their importance in reverse logistics for recycling. Since consumer is the first intervenient in any reverse system that aims to recycle household residues, the provision of an adequate customer service gains an increased importance. Applying multivariate statistical methods (exploratory factor analysis, confirmatory factor analysis and discriminant analysis to the data from a sample of 267 Portuguese citizens, this study identifies the levels of customer service in this reverse logistics chain and evaluates their relative importance in achieving consumers’ participation. The study finds that, as in forward logistics, the customer service in reverse channels for recycling also has a hard and a soft level, being the former more important than the later. The results of this research suggest important guidelines to improve such a complex logistics service.

    There are three timing of disaster mitigation which is pre-disaster, emergency response and post-disaster. All of those is important in disaster mitigation, but emergency response is important when we are talking about time. Emergency response has limited time when we should give help. Rapid assessment of kind of logistic, the number of survivors, number children and old people, their gender and also for difable person. It should be done in emergency response time. Therefore we make a mobile application for logistics management system. The name of application is dLOGIS, i.e. Disaster Logistics Information System. The application is based on Android system for mobile phone. Otherwise there is also website version. The website version is for maintenance, data input and registration. So the people or government can use it directly when there is a disaster. After login in dLOGIS, there is five main menus. The first main menu shows disaster information, refugees conditions, logistics needed, available logistics stock and already accepted logistics. In the second menu is used for entering survivors data. The field coordinator can enter survivors data based on the rapid assessment in disaster location. The third menu is used for entering kind of logistic. Number and kind of logistics are based on the BNPB needed standard for the survivor. The fourth menu displays the logistics stock available in field coordinator. And the last menu displays the logistics help that already accepted and sent by donation. By using this application when a disaster happened, field coordinator or local government can use maintenance distribution of logistics base on their needs. Also for donor people who will give help to survivor, they can give logistics with the corresponding of survivor needs.

    1996-12-31

    The main aim of the project is to model the energy wood business and total logistics in a certain large region. First, wood utilisation locations inside this area are examined; the most important ones are the wood processing factories, and the heating- and power plants. After that, wood potentials in the forests of the area are evaluated in sub-areas suitable in size and sufficiently detailed for further evaluations. For that purpose, the most valuable source data are forest management plans, up to ten years forward, on which basis the wood fuel potentials can be evaluated following sustainable development. In Finland there are extensive and detailed data bases storing forest information and it is possible to collect necessary data for a data base applicable to our calculations. In logistical sense it is important to know, by which delivery chains the economically best and desired results are achieved. The software prototype based on data base is modelled and developed at VTT Energy, for facilitating these planning activities. The starting point of the planning system in delivery logistics is the implementation of an easy tool for versatile planning so that with this tool model different delivery chains can be flexiblyed, create usage scenarios, make alternative examinations, and calculate impacts of different factors on energy wood amounts yielded and delivery costs. With planning system in delivery logistics we calculate production costs and amounts delivered to different utilisation locations. The system offers tools for definitions of utilisation locations, calculation parameters, and delivery chains

    Broyan, James L., Jr.; Ewert, Michael K.; Fink, Patrick W.

    2014-01-01

    Human exploration missions under study are limited by the launch mass capacity of existing and planned launch vehicles. The logistical mass of crew items is typically considered separate from the vehicle structure, habitat outfitting, and life support systems. Although mass is typically the focus of exploration missions, due to its strong impact on launch vehicle and habitable volume for the crew, logistics volume also needs to be considered. NASA's Advanced Exploration Systems (AES) Logistics Reduction and Repurposing (LRR) Project is developing six logistics technologies guided by a systems engineering cradle-to-grave approach to enable after-use crew items to augment vehicle systems. Specifically, AES LRR is investigating the direct reduction of clothing mass, the repurposing of logistical packaging, the use of autonomous logistics management technologies, the processing of spent crew items to benefit radiation shielding and water recovery, and the conversion of trash to propulsion gases. Reduction of mass has a corresponding and significant impact to logistical volume. The reduction of logistical volume can reduce the overall pressurized vehicle mass directly, or indirectly benefit the mission by allowing for an increase in habitable volume during the mission. The systematic implementation of these types of technologies will increase launch mass efficiency by enabling items to be used for secondary purposes and improve the habitability of the vehicle as mission durations increase. Early studies have shown that the use of advanced logistics technologies can save approximately 20 m(sup 3) of volume during transit alone for a six-person Mars conjunction class mission.

    2014-06-01

    Full Text Available In recent years, enterprises are required to reconsider the management of logistics activities as a result of developments such as increasing competition, rapid technological development, and the shortening of product life cycles. As a result of globalization, costs of logistics activities have also increased depending on changes in the quality and quantity of logistics activities. According to research on logistics activities, the physical distribution costs of enterprises may reach up to 30% of sales. For this reason, the management of logistics operations and control of costs caused by these activities is a necessity. The increase in costs negatively impact on the financial performance of enterprises, cash flows, profitability and so value of the shares. The aim of this study was to describe the structure of logistics costs and logistics activities to explain the methods used in costing. For this purpose, many studies in the literature were investigated.

Over time, partial innovations reached a high level of synthesis, leading to new management systems able to function in most complex task conditions. Mastering the procedure of creating autonomous partial information systems-where the operational research methods helped to optimally apply some of their particular values - has led to the creation of integrated automated information systems for management support. Our recent defense theory and practice have not concentrated enough on logistics information systems in professional journals, neither from the organizational nor from the technological point of view. Experiences gained from operational practice and knowledge acquired by visiting foreign armies, practical needs as well as modern times demands and current trends in the development of defense systems pointed out that it is necessary to pay more attention to this logistics segment in military journals. Logistics information systems cannot be researched, developed and introduced into operational practice

    An integrated logistics support system, which would provide routine access to space and be cost-competitive as an operational space transportation system, was planned and implemented to support the NSTS program launch-on-time goal of 95 percent. A decision was made to centralize the Shuttle logistics functions in a modern facility that would provide office and training space and an efficient warehouse area. In this warehouse, the emphasis is on automation of the storage and retrieval function, while utilizing state-of-the-art warehousing and inventory management technology. This consolidation, together with the automation capabilities being provided, will allow for more effective utilization of personnel and improved responsiveness. In addition, this facility will be the prime support for the fully integrated logistics support of the operations era NSTS and reduce the program's management, procurement, transportation, and supply costs in the operations era.

    To assess the immediate effects on vertical mouth opening, orofacial mechanosensitivity, and lumbar and suboccipital mobility after adding a myofascial induction technique to a multimodal protocol in subjects with temporomandibular disorders (TMD). A randomized and double-blind controlled trial was carried out. University-based physical therapy research clinic. Sixty subjects (35±11.22 years) with TMD, and restricted mobility of the mandibular condyles and the first cervical vertebrae, were recruited and randomized to either a control group (CG) (n=30) or an experimental group (EG) (n=30). The CG underwent a neuromuscular technique over the masseter muscles and passive hamstring muscle stretching. A suboccipital muscle inhibition technique was added to this protocol in the EG. Primary measurements were made of vertical mouth opening and pressure pain threshold of the masseter muscles. Secondary outcome measures included pressure algometry of the trigeminal nerve, suboccipital range of motion, and lumbar spine mobility, assessed with the sit-and-reach (SAR) test and lumbar forward bending. All evaluations were collected at baseline and immediately after intervention. In the intragroup comparison, the EG observed an increase in suboccipital flexion (p0.05). The inclusion of a myofascial induction maneuver in a protocol combining local (neuromuscular treatment) and distal techniques (hamstring stretching) in subjects with TMD has no impact on improving mouth opening, suboccipital and lumbar mobility, and orofacial sensitivity to mechanical pressure.

    Full Text Available City logistics studies the best solutions for urban freight distribution with high environmental objectives. However, most actions are started by public authorities without taking into account the impacts of the new organizational schemas in the existing distribution enterprises’ organization. This paper shows how city logistics approaches can meet the goals of Sustainable Development. In order to define the notion of sustainable city logistics, the main aspects of each sphere of sustainable development, respectively economic, environmental and societal, have been investigated. The main aspects of each sphere are described in order to unify the concept of sustainability related to city logistics. Then, we present the successful experience of Cityporto, the urban delivery service for the city of Padova (Italy, started in 2004 that uses low-pollution lorries. So, the service is considered as less polluting as a conventional approach, and is allowed to enter the city centre (including the Limited Traffic Zone without hour limitations.The study is based on the findings from an exploratory qualitative approach, based on a documentary analysis and a case study research from several interviews that involved three internal stakeholders of Interporto di Padova (the company which manages the intermodal platform of Padova, in charge of Cityporto and one member of Padova’s Municipality (which promote the project.The results of the case study show that environmental aspect is one of the foundations of the project, but the economic continuity has to be first ensured. Indeed, the preservation of this service on the long term is subjected to its solvency. Moreover, its success is associated to the recognition by employees and customers. With regard to the collected information, it is possible to propose a balanced scorecard, where three axes emerged in connexion with economic, environmental and social dimensions. From this qualitative analysis, a discussion

    2012-11-01

    Full Text Available The exact calculation of logistics costs has become a real challenge in logistics and supply chain management. It is essential to gain reliable and accurate costing information to attain efficient resource allocation within the logistics service provider companies. Traditional costing approaches, however, may not be sufficient to reach this aim in case of complex and heterogeneous logistics service structures. So this paper intends to explore the ways of improving the cost calculation regimes of logistics service providers and show how to adopt the multi-level full cost allocation technique in logistics practice. After determining the methodological framework, a sample cost calculation scheme is developed and tested by using estimated input data. Based on the theoretical findings and the experiences of the pilot project it can be concluded that the improved costing model contributes to making logistics costing more accurate and transparent. Moreover, the relations between costs and performances also become more visible, which enhances the effectiveness of logistics planning and controlling significantly

    2013-05-01

    Full Text Available Logistics is perceived to be important for Namibia’s growth and development, but this may be a matter of conjecture as there is a dearth of documented information about the industry in Namibia. Furthermore, it is uncertain what the understanding of logistics is for key stakeholders in the country. This article reports on a project; the objectives were to address some of these issues and to lay the foundation for a more thorough investigation in the future. The findings of the initial project were disseminated in 2012 by: a conference paper showing the challenges and opportunities facing logistics in Namibia in 2012; a report; and through a Logistics and Transport Workshop held in Walvis Bay, Namibia in September 2012. These reports, additional interviews and subsequent discussions highlighted some potential opportunities and problems. This article summarises the project to date, showing the methodology and findings as updated by subsequent feedback and further interviews. The findings from key stakeholders of the logistics industry in Namibia include: universal agreement on the importance of logistics to Namibia; the variety in the understanding of the term logistics; the strength of the continuing influence of South Africa as the dominant economic power in southern Africa; and contrasting views on the main factors limiting logistics development, including infrastructure, attitude, government, customs, training, railways, corruption and driver shortage.

    Full Text Available Abstract Background Directed ultrasonic screening for carotid stenosis is cost-effective in populations with > 5% prevalence of the diagnosis. Occasionally, calcifications in the area of the carotid arteries are incidentally detected on odontological panoramic radiographs. We aimed to determine if directed screening for carotid stenosis with ultrasound is indicated in individuals with such calcifications. Methods This was a cross-sectional study. Carotid ultrasound examinations were performed on consecutive persons, with findings of calcifications in the area of the carotid arteries on panoramic radiography that were otherwise eligible for asymptomatic carotid endarterectomy. Results Calcification in the area of the carotid arteries was seen in 176 of 1182 persons undergoing panoramic radiography. Of these, 117 fulfilled the inclusion criterion and were examined with carotid ultrasound. Eight persons (6.8%; 95% CI 2.2-11.5% had a carotid stenosis - not significant over the 5% pre-specified threshold (p = 0.232, Binomial test. However, there was a significant sex difference (p = 0.008, as all stenoses were found in men. Among men, 12.5% (95%CI 4.2-20.8% had carotid stenosis - significantly over the 5% pre-specified threshold (p = 0.014, Binomial test. Conclusions The incidental finding of calcification in the area of the carotid arteries on panoramic radiographs should be followed up with carotid screening in men that are otherwise eligible for asymptomatic carotid endarterectomy.

The companies’dependence from the strategic decisions belonging to the supply chain stands as a reason for the ever growinginterest towards Supply Chain Management and towards applying innovative processes that will offer anadvantage when faced with increasingly tougher competition from domestic or foreign companies. Thecompany’s characteristics can be subject to deep changes through decisions pertaining to the supply chain;these decisions are vital to the company’s productivity and competitiveness. If the logistics’ role in increasingthe company’s profitability is acknowledged, then implementing complex technologies and investing multiplefactors into improving logistical performance is fully justified. Customer orientation and focusing on keyactivities, which need to be performed daily in order to meet customer demand are absolutely necessary in asystem which implies fast reaction to market changes. The managerial way of thinking has changedsignificantly in the last years, because of the highly global competitiveness, the pressure to reduce costs,focusing on the company’s central competence. The principle of functioning is an aggregate system approachfor the entire flow of information, materials and services beginning with supply of raw material, processesand movements inside the factories and warehouses, until the products reach the final customer.

    Full Text Available Logistics centers have emerged as an important logistics infrastructure in supply chains. Hence, the problem of locating logistics centers plays a crucial role in designing and practicing logistics and supply chain management. Acknowledging the significance of logistics centers, Vietnam approved a master plan for the development of a logistics center system. However, the plan has been difficult to implementation because of the lack of the prioritization of the determinants used to locate logistics centers. This study aims to develop a benchmarking framework for choosing the locations of logistics centers based on the findings of logisticians by applying a hybrid of the fuzzy method and the technique for order of preference by similarity to ideal solution (TOPSIS, both of which are utilized extensively to overcome problems in selecting locations. The results indicate that freight demand, closeness to market, production area, customers, and transportation costs are regarded as the most important factors in deciding the location of logistics centers. In addition, among the three locations considered, the northeast provinces of Ho Chi Minh City were the best location for logistic centers, followed by North Hanoi and Da Nang city. The findings of this study make a significant contribution to both academic and practical aspects of locating logistic centers.

    The extensive logistics required to support extended crewed operations in space make effective modeling of logistics requirements and deployment critical to predicting the behavior of human lunar exploration systems. This paper discusses the software that has been developed as part of the Campaign Manifest Analysis Tool in support of strategic analysis activities under the Constellation Architecture Team - Lunar. The described logistics module enables definition of logistics requirements across multiple surface locations and allows for the transfer of logistics between those locations. A key feature of the module is the loading algorithm that is used to efficiently load logistics by type into carriers and then onto landers. Attention is given to the capabilities and limitations of this loading algorithm, particularly with regard to surface transfers. These capabilities are described within the context of the object-oriented software implementation, with details provided on the applicability of using this approach to model other human exploration scenarios. Some challenges of incorporating probabilistics into this type of logistics analysis model are discussed at a high level.

    I was assigned to the Logistics Division of the International Space Station (ISS)/Spacecraft Processing Directorate. The Division consists of eight NASA engineers and specialists that oversee the logistics portion of the Checkout, Assembly, and Payload Processing Services (CAPPS) contract. Boeing, their sub-contractors and the Boeing Prime contract out of Johnson Space Center, provide the Integrated Logistics Support for the ISS activities at Kennedy Space Center. Essentially they ensure that spares are available to support flight hardware processing and the associated ground support equipment (GSE). Boeing maintains a Depot for electrical, mechanical and structural modifications and/or repair capability as required. My assigned task was to learn project management techniques utilized by NASA and its' contractors to provide an efficient and effective logistics support infrastructure to the ISS program. Within the Space Station Processing Facility (SSPF) I was exposed to Logistics support components, such as, the NASA Spacecraft Services Depot (NSSD) capabilities, Mission Processing tools, techniques and Warehouse support issues, required for integrating Space Station elements at the Kennedy Space Center. I also supported the identification of near-term ISS Hardware and Ground Support Equipment (GSE) candidates for excessing/disposition prior to October 2010; and the validation of several Logistics Metrics used by the contractor to measure logistics support effectiveness.

    Technologies that reduce logistical mass, volume, and the crew time dedicated to logistics management become more important as exploration missions extend further from the Earth. Even modest reductions in logical mass can have a significant impact because it also reduces the packing burden. NASA's Advanced Exploration Systems' Logistics Reduction Project is developing technologies that can directly reduce the mass and volume of crew clothing and metabolic waste collection. Also, cargo bags have been developed that can be reconfigured for crew outfitting and trash processing technologies to increase habitable volume and improve protection against solar storm events are under development. Additionally, Mars class missions are sufficiently distant that even logistics management without resupply can be problematic due to the communication time delay with Earth. Although exploration vehicles are launched with all consumables and logistics in a defined configuration, the configuration continually changes as the mission progresses. Traditionally significant ground and crew time has been required to understand the evolving configuration and locate misplaced items. For key mission events and unplanned contingencies, the crew will not be able to rely on the ground for logistics localization assistance. NASA has been developing a radio frequency identification autonomous logistics management system to reduce crew time for general inventory and enable greater crew self-response to unplanned events when a wide range of items may need to be located in a very short time period. This paper provides a status of the technologies being developed and there mission benefits for exploration missions.

  5. The Relationship between Logistics Sophistication and Drivers of the Outsourcing of Logistics Activities

    2008-10-01

    Full Text Available A strong link has been established between operational excellence and the degree of sophistication of logistics organization, a function of factors such as performance monitoring, investment in Information Technology [IT] and the formalization of logistics organization, as proposed in the Bowersox, Daugherty, Dröge, Germain and Rogers (1992 Leading Edge model. At the same time, shippers have been increasingly outsourcing their logistics activities to third party providers. This paper, based on a survey with large Brazilian shippers, addresses a gap in the literature by investigating the relationship between dimensions of logistics organization sophistication and drivers of logistics outsourcing. To this end, the dimensions behind the logistics sophistication construct were first investigated. Results from factor analysis led to the identification of six dimensions of logistics sophistication. By means of multivariate logistical regression analyses it was possible to relate some of these dimensions, such as the formalization of the logistics organization, to certain drivers of the outsourcing of logistics activities of Brazilian shippers, such as cost savings. These results indicate the possibility of segmenting shippers according to characteristics of their logistics organization, which may be particularly useful to logistics service providers.

  6. A robust optimization model for green regional logistics network design with uncertainty in future logistics demand

    2015-12-01

    Full Text Available This article proposes a new model to address the design problem of a sustainable regional logistics network with uncertainty in future logistics demand. In the proposed model, the future logistics demand is assumed to be a random variable with a given probability distribution. A set of chance constraints with regard to logistics service capacity and environmental impacts is incorporated to consider the sustainability of logistics network design. The proposed model is formulated as a two-stage robust optimization problem. The first-stage problem before the realization of future logistics demand aims to minimize a risk-averse objective by determining the optimal location and size of logistics parks with CO2 emission taxes consideration. The second stage after the uncertain logistics demand has been determined is a scenario-based stochastic logistics service route choices equilibrium problem. A heuristic solution algorithm, which is a combination of penalty function method, genetic algorithm, and Gauss–Seidel decomposition approach, is developed to solve the proposed model. An illustrative example is given to show the application of the proposed model and solution algorithm. The findings show that total social welfare of the logistics system depends very much on the level of uncertainty in future logistics demand, capital budget for logistics parks, and confidence levels of the chance constraints.

    Full Text Available Background: Logistic Service Providers main concern was to ensure reliability for a low price (Christopher, 2005. Dutch Logistic Service Providers still have these two aspects at the top of their list, but also have to take in a new aspect: sustainability. 88% Of the investigated Logistic Service Providers have included sustainability in the company's goals. These Logistic Service Providers have developed different strategies to achieve a higher level of sustainability. This paper presents the results of a study into what Logistic Service Providers say what they are doing, or intend to do, to improve sustainability for their transport services. In this way insight is given in the attitude of Dutch Logistic Service Providers towards sustainability and how they intend to translate this into business practise: internal solutions or new methods incorporating external partners. Methods: Various methods of the investigations were used, among which the analysis of the statements about the sustainabilityon the websites of various companies as well as the questionnaire per Internet. The research covered 50 largest logistics companies operating in the Netherlands and 60 companies that competed for the award "Lean and Green" advertised in the Netherlands. In addition, the Internet survey was answered by 41 companies that belong to the network of our university. Results: The investigation has shown that sustainability is handled by the logistics company as an integral part of the corporate strategy. In contrast, shippers depend in the choice of logistics services primarily on such classical aspects as the reliability or the price and the sustainability play a minor role. Conclusions: Trying to find methods to improve the sustainability, Dutch logistics service providers, in the first place, look for solutions that increase the efficiency and therefore the cost reduction potential. Solutions, which require the involvement of clients, were less often

The main methods, used in this work are as follows: method of system analysis, method of the theory of operations’ research, prognostics. Application of these methods allows forecasting material flows, creating the integrated management systems and controlling their movements, developing systems of logistic service, to optimize supply stock and solve a number of other tasks.A logistic approach to form a modern system of logistics will save time, reduce costs for the purchase of material resources, their delivery and storage.In modern conditions of the market economy, the considered time parameters of the logistic chain are essential for manufacturing enterprises because their records significantly increase the efficiency of the logistical system.Logistics is equipped with a special complex of economic and mathematical models, the main feature of which is the adaptability, i.e. ability to solve complex optimization problems in the operational mode and in the process of the management of material flows. The primary role of these models in a market economy is to identify quickly points of compromise.Dynamics to functional cycles gives the necessity to align resource needs «input» and «output». «Input» functional cycle is an order that specifies requirements for a product or service.

    This study aimed to assess the nutritional status, measured by MNA, and its association with socio-demographic indicators and health related characteristics of a representative sample of community dwelling elderly subjects. Cross-sectional study. Community dwelling elderly individuals living in rural communities in Lebanon. 1200 elderly individuals aged 65 years or more. Socio-demographic indicators and health related characteristics were recorded during a standardized interview. Nutritional status was assessed through Mini Nutritional Assessment (MNA). The 5-item GDS score and the WHO-5-A score were used to assess mood, whereas Mini Mental Status (MMS) was applied to evaluate cognitive status. The prevalence of malnutrition and risk of malnutrition was 8.0% respective 29.1% of the study sample. Malnutrition was significantly more frequent in elderly subjects aged more than 85 years, in females, widowed and illiterate people. Moreover, participants who reported lower financial status were more often malnourished or at risk of malnutrition. Regarding health status, poor nutritional status was more common among those reporting more than three chronic diseases, taking more than three drugs daily, suffering from chronic pain and those who had worse oral health status. Also, depressive disorders and cognitive dysfunction were significantly related to malnutrition. After multivariate analysis following variables remained independently associated to malnutrition: living in the governorate of Nabatieh (ORa 2.30, 95% CI 1.35 -3.93), reporting higher income (ORa 0.77, 95% CI 0.61-0.97), higher number of comorbidities (ORa 1.22, 95% CI 1.12-1.32), chronic pain (ORa 1.72, 95% CI 1.24-2.39), and depressive disorders (ORa 1.66, 95% CI 1.47-1.88). On the other hand, better cognitive functioning was strongly associated with decreased nutritional risk (ORa 0.27, 95%CI 0.17-0.43). Our results highlighted the close relationship between health status and malnutrition. The

    2011-02-01

    This study explores the psychosocial working conditions of 7930 Swedish 9th grade students, distributed over 475 classes and 130 schools, in relation to their subjective health using multilevel modeling. At the individual level, students with "strained" working conditions in school (i.e. those experiencing a high level of demands in combination with a low level of control) demonstrated significantly worse health compared to students in "low-strain" situations. "Strained" conditions in combination with a weak school-related sense of coherence were especially unfavourable for health. These findings remained significant when support from teachers, school marks, norm-breaking behaviours, family-relations and certain class- and school-contextual conditions were adjusted for. Thus, while demands are an essential part of school work, this study suggests that high levels of control and a strong school-related sense of coherence can protect against the more detrimental effects on health that high demands at school may cause.

    Logistics have always been a vital part of polar exploration and research. The more efficient those logistics can be made, the greater the likelihood that research programmes will be delivered on time, safely and to maximum scientific effectiveness. Over the last decade, the potential for symbiosis between logistics and some of the scientific research methods themselves, has increased remarkably; suites of scientific tools can help to optimise logistic efforts, thereby enhancing the effectiveness of further scientific activity. We present one recent example of input to logistics from scientific activities, in support of the NERC iSTAR Programme, a major ice sheet research effort in West Antarctica. We used data output from a number of research tools, spanning a range of techniques and international agencies, to support the deployment of a tractor-traverse system into a remote area of mainland Antarctica. The tractor system was deployed from RRS Ernest Shackleton onto the Abbot Ice Shelf then driven inland to the research area in Pine Island Glacier Data from NASA ICEBRIDGE were used to determine the ice-front freeboard and surface gradients for the traverse route off the ice shelf and onwards into the continent. Quickbird high resolution satellite imagery provided clear images of route track and some insight into snow surface roughness. Polarview satellite data gave sea ice information in the Amundsen Sea, both the previous multi-annual historical characteristics and for real-time information during deployment. Likewise meteorological data contributed historical and information and was used during deployment. Finally, during the tractors' inland journey, ground-based high frequency radar was used to determine a safe, crevasse-free route.

    Full Text Available Ḥalāl is no longer understood as solely concerning food consumption or ritual slaughter. It is at the centre of the global Muslim food industry and logistics is one of its driving forces. The growing demand for ḥalāl food integrity contributes to the need for ḥalāl logistics. However, ḥalāl logistics operation has thus far not been warmly received by the industry thus hampering the availability of such services. This conceptual study attempts to illuminate the issue by addressing ḥalāl logistics from a marketing perspective. The concept of marketing mix and how it can be practiced by industrial players in marketing or promoting ḥalāl logistics services underpins our discussion. Existing literature is reviewed and discussed to ascertain the link between ḥalāl logistics and the 7Ps of its marketing mix, namely, product, place, price, promotion, people, process, and programme.

    2013-01-01

    In modern logistics operations, large-scale logistics companies, besides active participation in profit-seeking commercial business, also play an essential role during an emergency relief process by dispatching urgently-required materials to disaster-affected areas. Therefore, an issue has been widely addressed by logistics practitioners and caught researchers' more attention as to how the logistics companies achieve maximum commercial profit on condition that emergency tasks are effectively and performed satisfactorily. In this paper, two vehicle scheduling models are proposed to solve the problem. One is a prediction-related scheme, which predicts the amounts of disaster-relief materials and commercial business and then accepts the business that will generate maximum profits; the other is a priority-directed scheme, which, firstly groups commercial and emergency business according to priority grades and then schedules both types of business jointly and simultaneously by arriving at the maximum priority in total. Moreover, computer-based simulations are carried out to evaluate the performance of these two models by comparing them with two traditional disaster-relief tactics in China. The results testify the feasibility and effectiveness of the proposed models.

    Logistics activities play a prominent role in enabling manufacturers, distribution channels, and pharmacies to work in harmony. Nowadays these activities have become increasingly striking in the pharmaceutical industry and seen as a development area for this sector. Additionally, green practices are beginning to be more attracting particularly in decreasing costs and increasing image of pharmaceutical companies. The main objective of this study was modeling green logistics (GL) behavior of the managers in the pharmaceutical sector in the theory of planned behavior (TPB) frame via structural equation modeling (SEM). A measurement tool was developed according to TPB. Exploratory factor analysis was conducted to determine subfactors of GL behavior. In the second step, confirmatory factor analysis (CFA) was conducted for confirming whether there is a relationship between the observed variables and their underlying latent constructs. Finally, structural equation model was conducted to specify the relationships between latent variables. In the proposed green logistics behavior (GLB) model, the positive effect of environmental attitude towards GL, perceived behavioral control related GL, and subjective norm about GL on intention towards GL were found statistically significant. Nevertheless, the effect of attitude towards costs of GL on intention towards GL was not found statistically significant. Intention towards GL has been found to have a positive statistically significant effect on the GL behavior. Based on the results of this study, it is possible to say that TPB is an appropriate theory for modeling green logistics behavior of managers. This model can be seen as a guide to the companies in the pharmaceutical sector to participate in green logistics. Copyright © 2017 Elsevier Inc. All rights reserved.

    2011-08-01

    Full Text Available Transportations take an essential role in logistics, interconnecting the majority of processes and operations within logistic system. The efficient use of transportation capacity is a priority whose achievement can diminish logistic costs. This objective is today difficult to achieve due to increasing complexity of transportation monitoring and coordination. This complexity is determined by transportation number and diversity, by the volume and diversity of orders, by increasing the targets to be supplied.Dynamic programming represents a highly useful tool for logistic managers, considering that its specific techniques and methods are oriented toward solving problems related to resource optimum allocation and utilization.The present paper presents briefly a series of theoretical elements of dynamic programming applied in logistics, based on which it is shown a mathematic model to determine the optimum policy for transport capacity repartition for the area attached to a logistic centre, through three distribution centres.

    In order to assess the quality of streams susceptible to contamination by pesticides we apply biochemical and genotoxic biomarkers in the Neotropical fish Prochilodus lineatus submitted to in situ tests. Fish were caged, for 96 h, in two streams located in areas with intensive use of pesticides, the Apertados (AP) and the Jacutinga (JC), and in a small stream (Godoy stream — GD) found inside a forest fragment adjacent to a State Park. Biochemical parameters, such as biotransformation enzymes 7-ethoxyresorufin-O-deethylase (EROD) and glutathione-S-transferase (GST), non-protein thiols (NPSH), lipoperoxidation (LPO), protein carbonylation (PCO) and acetylcholinesterase (AChE) were evaluated in various fish organs, as well as genotoxic biomarkers (damage to DNA and occurrence of micronuclei and erythrocyte nuclear abnormalities). Samples of water and sediment were collected for analysis of metals (Cu, Cr, Pb, Ni, Mn, Cd and Zn), organochloride pesticides, and triazine and glyphosate herbicides. We observed an increase in liver GST activity in fish at AP and gill GST activity in fish at JC. An increase in liver LPO was also observed in fish exposed to AP and JC. The same animals also exhibited increased DNA damage and erythrocyte nuclear abnormalities (ENAs) compared to the fish kept in GD. A number of compounds showed concentrations higher than the permitted levels, in particular, dichlorodiphenyltrichloroethane (DDT), its metabolites dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexanes (HCH), heptachloride, diclofluanid and aldrins. These pesticides were detected at higher concentrations in water and sediment samples from AP, followed by JC and GD. The Integrated Biomarker Response Index (IBR) indicated that AP and JC (AP: 21.7 > JC: 18.5 > GD: 12.6) have the worst environmental quality. Integrated biomarker analysis revealed that the alterations observed related well with the levels of environmental contaminants

    2011-12-01

    Full Text Available To characterize the geological, hydrogeological, hydrochemical, and hydrobacterial aspects of the surface and groundwater in the floodplain of the Paraíba do Sul river in Tremembé municipality, the water levels of the Quaternary sedimentary aquifer experimental site was monitored based on four wells and eight associated piezometers with daily measures of water levels in continuous operation since December 3, 2009. In addition, data from a modular weather station in operation since March 2010 and data from the quality of surface water and groundwater have been analyzed in the period between March 2010 and March 2011. The water balance between April 2010 and March 2011 was estimated to verify the periods of water deficiency and excess. Data loggers installed in the piezometers enabled daily groundwater levels monitoring to establish the influence of the Paraíba do Sul river in the water levels of the Quaternary sedimentary aquifer and also they allowed the determination of the water loss to the atmosphere. A hydrogeological model with simplified equations, based on hydraulics parameters obtained in the wells pump tests, was implemented to calculate the amount of daily evapotranspiration and the average distance of the water loss from the wells to the atmosphere. An evaporation rate of 83.4 m3/h from the open-pit sand mine located at 212.2 m and of 89.2 m3/h for the one at 885.0 m average distance from the monitoring wells were observed. Chemical and bacteriological analysis involving multiple parameters were performed in the period from March 2010 to March 2011 in groundwater collected in wells, in the open-pit mines and in the waters of the Paraíba do Sul river. The results allowed to observe the influences of the Paraíba do Sul river as well as the contamination from fertilizers and pesticides from the agriculture practiced in the floodplain area on the quality of the groundwater.

    The Vision for Space Exploration sets out a number of goals, involving both strategic and tactical objectives. These include returning the Space Shuttle to flight, completing the International Space Station, and conducting human expeditions to the Moon by 2020. Each of these goals has profound logistics implications. In the consideration of these objectives,a need for a study on NASA logistics lessons learned was recognized. The study endeavors to identify both needs for space exploration and challenges in the development of past logistics architectures, as well as in the design of space systems. This study may also be appropriately applied as guidance in the development of an integrated logistics architecture for future human missions to the Moon and Mars. This report first summarizes current logistics practices for the Space Shuttle Program (SSP) and the International Space Station (ISS) and examines the practices of manifesting, stowage, inventory tracking, waste disposal, and return logistics. The key findings of this examination are that while the current practices do have many positive aspects, there are also several shortcomings. These shortcomings include a high-level of excess complexity, redundancy of information/lack of a common database, and a large human-in-the-loop component. Later sections of this report describe the methodology and results of our work to systematically gather logistics lessons learned from past and current human spaceflight programs as well as validating these lessons through a survey of the opinions of current space logisticians. To consider the perspectives on logistics lessons, we searched several sources within NASA, including organizations with direct and indirect connections with the system flow in mission planning. We utilized crew debriefs, the John Commonsense lessons repository for the JSC Mission Operations Directorate, and the Skylab Lessons Learned. Additionally, we searched the public version of the Lessons Learned

    2013-11-01

    Full Text Available In the conditions of globalization and the world economic communications, the role of information support of business processes increases in various branches and fields of activity. There is not an exception for the warehouse activity. Such information support is realized in warehouse logistic systems. In relation to territorial administratively education, the warehouse logistic system gets a format of difficult social and economic structure which controls the economic streams covering the intermediary, trade and transport organizations and the enterprises of other branches and spheres. Spatial movement of inventory items makes new demands to participants of merchandising. Warehousing (in the meaning – storage – is one of the operations entering into logistic activity, on the organization of a material stream, as a requirement. Therefore, warehousing as "management of spatial movement of stocks" – is justified. Warehousing, in such understanding, tries to get rid of the perception as to containing stocks – a business expensive. This aspiration finds reflection in the logistic systems working by the principle: "just in time", "economical production" and others. Therefore, the role of warehouses as places of storage is transformed to understanding of warehousing as an innovative logistic system.

    Each year, millions of people worldwide are affected by disasters, underscoring the importance of effective relief efforts. Many highly visible disaster responses have been inefficient and ineffective. Humanitarian agencies typically play a key role in disaster response (eg, procuring and distributing relief items to an affected population, assisting with evacuation, providing healthcare, assisting in the development of long-term shelter), and thus their efficiency is critical for a successful disaster response. The field of disaster and emergency response modeling is well established, but the application of such techniques to humanitarian logistics is relatively recent. This article surveys models of humanitarian response logistics and identifies promising opportunities for future work. Existing models analyze a variety of preparation and response decisions (eg, warehouse location and the distribution of relief supplies), consider both natural and manmade disasters, and typically seek to minimize cost or unmet demand. Opportunities to enhance the logistics of humanitarian response include the adaptation of models developed for general disaster response; the use of existing models, techniques, and insights from the literature on commercial supply chain management; the development of working partnerships between humanitarian aid organizations and private companies with expertise in logistics; and the consideration of behavioral factors relevant to a response. Implementable, realistic models that support the logistics of humanitarian relief can improve the preparation for and the response to disasters, which in turn can save lives.

    CERN Document Server

    Bretzke, Wolf-Rüdiger

    2013-01-01

    Currently the notion of "sustainability" is used in an inflationary manner. Therefore the authors start with a definition which is stable to serve as an anchor for further research as well as for discussions among scientists, managers and politicians, ideally across different disciplines. The character of this book is purely conceptual. The argumentation is based on comparison of new and demanding requisites with existing models (process and network architectures in the field of logistics). Formerly neglected impacts on the environment will be included. Main features of a new approach will be developed which are capable to avoid these impacts and to align logistics with the requirements of sustainability. In order to make logistics sustainable large parts will have to be reinvented. The focus needs to be on decoupling transportation activities from economic growth rates.

    This paper addresses a comprehensive modeling and functionality evaluation of a module-based quality system in production logistics at the highest domain abstract level of business processes. All domain quality business processes and quality data transactions are modeled using BPMN and UML tools and standards at the business process and data modeling. A modular web-based prototype is developed to evaluate the models addressing the quality information system functionality requirements and modularity in production logistics through data scenarios and data queries. Using the object-oriented technique in design at the highest domain level, the proposed models are subject further development in the lower levels for the implementing case. The models are specifically able to manipulate all quality operations including remedy and control in a lot-based make-to-order production logistics system as an individual module. Due to the specification of system as domain design structure, all proposed BPMs, data models, and the actual database prototype are seen referential if not a solution as a practical “to-be” quality business process re-engineering template. This paper sets out to provide an explanatory approach using different practical technique at modeling steps as well as the prototype implementation. (Author)

    In Brazil most Construction and Demolition Waste (C&D waste) is not recycled. This situation is expected to change significantly, since new federal regulations oblige municipalities to create and implement sustainable C&D waste management plans which assign an important role to recycling activities. The recycling organizational network and its flows and components are fundamental to C&D waste recycling feasibility. Organizational networks, flows and components involve reverse logistics. The aim of this work is to introduce the concepts of reverse logistics and reverse distribution channel networks and to study the Brazilian C&D waste case.

    Collaborative logistics is becoming more important in today’s industry. This is driven by increased environmental concerns, improved efficiency through collaborative planning supporting resources sharing and new business models implementation. This paper explores collaborative logistics and reports on business applications within the forest products industry in Sweden and Canada. It first describes current opportunities in collaborative planning. It then discusses issues related to building the coalition as well as sharing resources and benefits. Three business cases are described and used to support the discussion around these main issues. Finally, different challenges are detailed, opening new paths for researchers in the field.

    Motor rehabilitation after brain damage relies on motor re-learning as induced by specific training. Non-invasive brain stimulation (NIBS) can alter cortical excitability and thereby has a potential to enhance subsequent training-induced learning. Knowledge about any priming effects of NIBS on motor learning in healthy subjects can help to design targeted therapeutic applications in brain-damaged subjects. To examine whether complex motor learning in healthy subjects can be enhanced by intermittent theta burst stimulation (iTBS) to primary motor or sensory cortical areas. Eighteen young healthy subjects trained eight different arm motor tasks (arm ability training, AAT) once a day for 5 days using their left non-dominant arm. Except for day 1 (baseline), training was performed after applying an excitatory form of repetitive transcranial magnetic stimulation (iTBS) to either (I) right M1 or (II) S1, or (III) sham stimulation to the right M1. Subjects were randomly assigned to conditions I, II, or III. A principal component analysis of the motor behaviour data suggested eight independent motor abilities corresponding to the 8 trained tasks. AAT induced substantial motor learning across abilities with generalisation to a non-trained test of finger dexterity (Nine-Hole-Peg-Test, NHPT). Participants receiving iTBS (to either M1 or S1) showed better performance with the AAT tasks over the period of training compared to sham stimulation as well as a bigger improvement with the generalisation task (NHPT) for the trained left hand after training completion. Priming with an excitatory repetitive transcranial magnetic stimulation as iTBS of either M1 or S1 can enhance motor learning across different sensorimotor abilities.

    Full Text Available Neste estudo, buscou-se aplicar o modelo de avaliação do desempenho logístico de cadeias produtivas (ADELCAP, baseado nos tempos dos elementos do ciclo operacional do transporte de madeira de áreas de fomento de uma empresa produtora de celulose do Estado do Espírito Santo, objetivando apontar meios de otimizar os recursos físicos para garantir um fluxo de abastecimento ininterrupto e apropriado volume de entrada de madeira nos depósitos regionais. O ciclo operacional de transporte de madeira é ordenado pelas atividades de carregamento de madeira no campo, viagem carregada, descarregamento no depósito e viagem vazia. Utilizou-se a Rede de Petri Temporal, por trabalhar com dois tempos duração de sensibilização. Realizaram-se simulações com os softwares JARP e ARP, a fim de simular, analisar e avaliar o desempenho operacional. As variações empregadas em cada cenário se devem à qualidade da estrada, sob as condições atuais quanto à geometria vertical e horizontal e ao quociente de irregularidade, em cada depósito para os diferentes tipos de veículo e forma de carregamento da madeira adotado. Nas regiões de topografia acidentada, a melhoria das estradas alterando seu nível de qualidade tem maior influência para o aumento do desempenho dos veículos, e os veículos 4x2 e 6x2 apresentaram os melhores resultados. Nas regiões de planícies, a escolha do veículo tem maior influência no aumento do desempenho do transporte, já que a topografia e qualidade das estradas atuais já contribuem para isso. Nesses casos, a relação tonelada transportada por distância e tempo será maior para os veículos com capacidade de carga líquida maior.This study aimed at applying the model of logistic performance evaluation of productive chains (ADELCAP, based on the times of the elements of the operational cycle of wood transport from areas of fomentation of a cellulose producing company in the State of Espírito Santo, to indicate means
