    One of the world`s first 500 kW turbines was installed in 1989 in the Netherlands. This forerunner of the current NedWind 500 kW range also represents the earliest predesign of the NedWind megawatt turbine. After the first 500 kW turbines with steel rotor blades and rotor diameter of 34 m, several design modifications followed, e.g. the rotor diameter was increased to 35 m and a tip brake was added. Later polyester blades were introduced and the rotor diameter was increased with 5 in. The drive train was also redesigned. Improvements on the 500 kW turbine concept has resulted in decreased cost, whereas annual energy output has increased to approx. 1.3 million kWh. Wind energy can substantially contribute to electricity supply. Maximum output in kiloWatthours is the target. Further improvement of the existing technology and implementation of flexible components may well prove to be a way to increase energy output, not only in medium or large sized wind turbines. 7 figs.

  4. AN INVESTIGATION INTO MEDIUM-SIZED MULTINATIONAL ENTERPRISES

    2013-09-01

    Full Text Available The paper provides an investigation of medium-sized Italian industrial enterprises that have become multinational companies. It concetrates on the set of medium and medium-large enterprises who seem to grow more in foreign markets, either through exports or through foreign direct investment. The work also offers a descriptive empirical picture of the performance of medium-sized Italian multinationals, which is compared with the performance of large corporations. From this analysis, which is based on several data sources, it is possible to outline a profile regarding the medium-size italian multinational enterprises; the aim is to understand the complex strategy towards internationalization of these companies, where the dimension of production is important and, therefore, innovation has a key role. Also the commercial dimension is crucial, because it leads to point to the direct supervision of foreign markets and to look very carefully at the customers, offering them a wide range of services. Finally, the paper highlights some critical issues that the medium sized multinational enterprises have to face for competing: namely, the stagnant productivity, the high taxation, the insufficient institutional support for internationalization, the bureaucracy and its high costs, the lack of skilled human capital available in the labor market due to inadequate policy training.

    2002-12-01

    Preliminary assessment for deployment of small-medium sized reactor (S and M reactor) as a future option has been conducted at the JAPCO (Japan Atomic Power Company) under the cooperation with the CRIERI (Central Research Institute of Electric Power Industry). Significance of the S and M reactor introduction is listed as follows; lower investment cost, possible siting near demand side, enlarged freedom of siting, shorter transmission line, good compatibility with slow increase of demand and plain explanation of safety using simpler system such as integral type vessel without piping, natural convection core cooling and passive safety system. The deployment of simpler plant system, modular shop fabrication, ship-shell structured building and longer operation period can assure economics comparable with that of a large sized reactor, coping with scale-demerit. Also the S and M reactor is preferable in size for the nuclear heat utilization such as hydrogen production. (T. Tanaka)

    SHEN, YAN; SHEN, MINGGAO; XU, ZHONG; BAI, YING

    2014-01-01

    Summary Using panel data collected in 2005, we evaluate how bank size, discretion over credit, incentive schemes, competition, and the institutional environment affect lending to small- and medium-sized enterprises in China. We deal with the endogeneity problem using instrumental variables, and a reduced-form approach is also applied to allow for weak instruments in estimation. We find that total bank asset is an insignificant factor for banks’ decision on small- and medium-enterprise (SME) lending, but more local lending authority, more competition, carefully designed incentive schemes, and stronger law enforcement encourage commercial banks to lend to SMEs.

    2015-08-01

    In this paper an attempt is made to estimate the main parameters of the Iranian superconducting tokamak as a medium sized tokamak. In the first stage, the production and confinement of ohmically heated plasma is considered. Considering the aim of the design and the kink stability limit, three main parameters are assumed to be known. Using the known theoretical, empirical scale laws and numerical solution of Grad-Shafranov equation for a D-shaped plasmas and also considering the correction terms due to triangularity of the torus cross section, other physical and geometrical parameters have been estimated. The magnetic flux surfaces, plasma pressure and toroidal current density profiles are found by solving of Grad-Shafranov equation as an eigenvalue problem using finite element method. The preliminary results are compared with some recent tokamaks now in operation in different research centers.

    Full Text Available This study aims to examine the role of entrepreneurial orientation (entrepreneurship orientation in innovation level among Small and Medium Size Enterprises (SMEs. A questionnaire survey was conducted among 137 firms in the Podlaskie Region. Three hypotheses related to entrepreneurial orientation and innovativeness level were examined by Structural Equation Modeling (SEM. The relation between two constructs of entrepreneurial orientation and innovativeness, that is proactiveness and risk taking were analyzed. The research results show that proactiveness has a significant positive total effect on improving innovativeness. The findings suggest, in contrast to the strategic orientation literature, that risk taking deters enterprises from organizational innovation. The results confirmed the significantly higher impact of the risk taking as an intermediate variable on the innovation through the mediator of proactivity. This work examines the relations between entrepreneurial orientation and innovativeness, thus contributes to the strategic orientation literature.

  3. Small and medium sized enterprises (SMEs and transfer pricing

    2012-01-01

    Full Text Available Small and medium sized enterprises have very important position in the EU economy, mainly in the area of growth and employment. However, most of SMEs are active only in their home country and only a few of them participate in cross-border activities. Furthermore, their activities in the internal market are limited by great deal of obstacles, mainly in the form of different tax systems which generate excessive compliance costs of taxation and the existence of different SMEs definitions for various purposes in Member states. In addition, from the view of the international taxation issues, the most important obstacles can be considered a transfer pricing and cross-border loss compensations. In this area, SMEs are facing specific problems and have specific needs. The aim of the paper is to analyze and evaluate the specific transfer pricing issues of SMEs and propose recommendations for them.

    2015-12-01

    Using the Community Earth System Model (CESM), a three-dimensional coupled climate model with interactive chemistry, we have simulated the climate response to a medium-sized (1 km) asteroid impact on the land. An impact of this size would cause local fires and may also generate submicron dust particles. Dust aerosols are injected into the upper atmosphere where they persist for ~3 years. Soot aerosols from fires are injected into the troposphere and absorb solar radiation heating the air which helps loft the soot into the stratosphere where it persists for ~10 years. Initially, these aerosols cause a heating of over 240 K in the stratosphere and up to a 70% reduction in downwelling solar radiation at the surface. Global average surface temperature cools by as much as -8.5 K, ocean temperature cools by -4.5 K, precipitation is reduced by 50%, and the ozone column is reduced by 55%. The surface UV Index exceeds 20 in the tropics for several years. These changes represent a significant hazard to life on a global scale. These results extend the work of Pierazzo et al. (2010), also using CESM, which found a significant impact on stratospheric ozone, but little change in surface temperature or precipitation, from a 1 km asteroid impact in the ocean.

    Satrec Initiative and ATSB have been developing a medium-sized aperture camera (MAC) for an earth observation payload on a small satellite. Developed as a push-broom type high-resolution camera, the camera has one panchromatic and four multispectral channels. The panchromatic channel has 2.5m, and multispectral channels have 5m of ground sampling distances at a nominal altitude of 685km. The 300mm-aperture Cassegrain telescope contains two aspheric mirrors and two spherical correction lenses. With a philosophy of building a simple and cost-effective camera, the mirrors incorporate no light-weighting, and the linear CCDs are mounted on a single PCB with no beam splitters. MAC is the main payload of RazakSAT to be launched in 2005. RazakSAT is a 180kg satellite including MAC, designed to provide high-resolution imagery of 20km swath width on a near equatorial orbit (NEqO). The mission objective is to demonstrate the capability of a high-resolution remote sensing satellite system on a near equatorial orbit. This paper describes the overview of the MAC and RarakSAT programmes, and presents the current development status of MAC focusing on key optical aspects of Qualification Model.

    2016-12-01

    Full Text Available Corporate social responsibility has become an important part of business activities of many organizations. Despite the fact that the corporate social responsibility as an institutionalized organizational management process has existed for more than 50 years, it has not yet received the deserved scientific attention, and its various aspects are still subject to debates. Given that small and medium-sized business organizations play an important role in the socio-economic development of the country, such a problem can become a significant barrier for increasing the efficiency of interaction of main actors and stakeholders of business activities in the country. Thus, it is crucial to study the priorities of small and medium-sized organizations in the corporate social responsibility field. The authors conducted an empirical exploratory study of the Russian small and medium-sized business organizations and found out that their representatives do not have a clear understanding of the directions and methods of implementing the social responsibility model. For instance, the standards developed for large organizations to implement the ideas of corporate social responsibility are too global and too costly for small and medium-sized businesses, however the latter in Russia still do not have their own technologies and algorithms for implementing an appropriate model of social responsibility (except for some types of charity and requirements to retrain workers, which are considered rather external claims.

    Full Text Available The authors prove that despite the active state policy carried out since the second half of the 2000s and aimed at supporting small and medium-sized business in the Russian Federation, the current level of development of this economic sector is insufficient. The present paper characterizes the modern structure of small and medium-sized business. The authors show that the main problems hindering its growth are conditioned by low market demand, large tax deductions, numerous administrative barriers, lack of funding and state support. On the basis of the official data of Russian Federal State Statistics Service on theresults of annual surveys of entrepreneurs, the authors revealed the factors that prevented innovation situation in the country have stable negative impact on MSB, while the impact of such factors as imperfect legal and regulatory framework, investment risks, low profitability and inadequate state of technological infrastructure is relatively nonsignificant. The authors describe systemwide and resource measures of state regulation of small and medium-sized business. The system-wide measures include preferential access to production facilities and equipment, special tax regimes, administrative control. The measures of resource support to entrepreneurs consist in subsidizing the lease payments and interest rates on loans for the modernization of production; grant support, the establishment of microfinance organizations and guarantee funds, the development of business support infrastructure. The authors describe the forms of these measures implementation in 2013 and the main directions of improving the state regulation of small and medium-sized business, including the reduction of tax burden and facilitation of taxation procedures, the reduction of administrative barriers and ensuring access of small and medium-sized enterprises to government orders and technological infrastructure.

  15. Measurement of Bubble Size Distribution Based on Acoustic Propagation in Bubbly Medium

    Wu, Xiongjun; Hsiao, Chao-Tsung; Choi, Jin-Keun; Chahine, Georges

    2013-03-01

    Acoustic properties are strongly affected by bubble size distribution in a bubbly medium. Measurement of the acoustic transmission becomes increasingly difficulty as the void fraction of the bubbly medium increases due to strong attenuation, while acoustic reflection can be measured more easily with increasing void fraction. The ABS ACOUSTIC BUBBLE SPECTROMETER®\\copyright, an instrument for bubble size measurement that is under development tries to take full advantage of the properties of acoustic propagation in bubbly media to extract bubble size distribution. Properties of both acoustic transmission and reflection in the bubbly medium from a range of short single-frequency bursts of acoustic waves at different frequencies are measured in an effort to deduce the bubble size distribution. With the combination of both acoustic transmission and reflection, assisted with validations from photography, the ABS ACOUSTIC BUBBLE SPECTROMETER®\\copyright has the potential to measure bubble size distributions in a wider void fraction range.

    2016-09-01

    Full Text Available This analysis investigates medium-sized towns in Poland, i.e. those with a population between 20–100 thousand, located up to 100 km away from the main city of the agglomeration. The aim of this article is to compare the level of socio-economic development of Polish towns depending on their location in relation to the main city in the largest agglomerations in 1998 and 2013. Three zones of distance from the main city of each agglomeration have been taken into consideration: a. the inner zone, reaching up to 25 km from the main city; b. the outer zone located at a distance of 25 to 50 km from the main city, and c. the peripheral zone, located at a distance of 50 to 100 km from the main city and including the medium-size towns located outside the agglomeration system. This analysis of the distribution of medium-sized towns and their level of socio-economic development has shown various levels of changes which depend on the distance from the main city of the agglomeration. In 1998, the highest level of development of the medium-sized towns was recorded in towns outside of these agglomeration systems, i.e. those located most remotely from the main city (peripheral zone. Most of the medium-sized towns are situated at a distance of 50–100 km from Warszawa, Kraków, Łódź, Lublin, Gdańsk and have developed their own local, or even regional labour markets and some of them have even provided administrative functions in the past as voivodeship capitals. Only in the Poznań agglomeration, the level of development of medium-sized towns was higher in the immediate surroundings of the main city (25 km. The medium-sized towns in all zones of the distance from the main city in the Wrocław agglomeration represented a similar level of development. By 2013, the level of development of the medium-sized towns in the peripheral zone in all investigated settlement systems had decreased, with a significant improvement in the level of development of the towns in

    Buildings consume over 40% of the total energy consumption in the U.S. A significant portion of the energy consumed in buildings is wasted because of the lack of controls or the inability to use existing building automation systems (BASs) properly. Much of the waste occurs because of our inability to manage and controls buildings efficiently. Over 90% of the buildings are either small-size (<5,000 sf) or medium-size (between 5,000 sf and 50,000 sf); these buildings currently do not use BASs to monitor and control their building systems from a central location. According to Commercial Building Energy Consumption Survey (CBECS), about 10% of the buildings in the U.S. use BASs or central controls to manage their building system operations. Buildings that use BASs are typically large (>100,000 sf). Lawrence Berkeley National Laboratory (LBNL), Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL) were asked by the U.S. Department of Energy’s (DOE’s) Building Technologies Program (BTP) to identify monitoring and control needs for small- and medium-sized commercial buildings and recommend possible solutions. This study documents the needs and solutions for small- and medium-sized buildings.

    French hydro-power buildings belong to the government and are retroceded by the licence holder when the granting delay comes to an end. Experience has shown that less care is given by licence holders to the maintenance of medium-size dams that to big dams. For this reason, the French Ministry of Industry decided to harmonize and standardize the surveillance practices of medium-size dams. A circular was signed on May 23, 1997 which concerns the 10 to 20 m height dams with water reservoir volumes lower than the H{sup 2} x V{sup 0.5} criterion which is an evaluation of the potential risk of the dam. The surveillance modalities concern: the construction, the licence holder file, the first filling up, the operation, and the periodical safety inspections. (J.S.)

    Ministry of the Environment (MD) wanted an overview of current knowledge of climate-friendly and attractive urban development in medium-sized cities (10 - 50 000 inhabitants). This report presents and discusses knowledge between major cities' situation and challenges of land use and transport development to reduce car traffic and greenhouse gas emissions and on urban development for more attractive cities. A main conclusion is that there are major gaps in knowledge and opportunities for improvement. If those covered will be far better opportunities for planners, local authorities and others may be able to contribute to more climate-friendly and attractive medium-sized cities.The report is part of the project Comprehensive information pack for the status of knowledge from research on urban development. The project has also prepared a report entitled Planning for attractive urban environment. The reports are intended to complement each other and should be seen in context.(eb)

    2017-10-01

    Earned Value Method (EVM) became in recent years the global standard for describing of the current time/budget status of engineering projects. It is the most preferred tool by international construction arbitrage bodies, in case the advancement of the construction project for a given date must be defined in a commonly recognizable way. Application of the method in every day site practice needs 2-3 people team dedicated just for that task, so the EVM it is used rather for large projects. However, using of the method in its reduced scale, as presented in the paper, can be fully economic also for medium size construction projects and provides set of information that can be very helpful for site managers in decision making processes. The numerical example of EVM used for medium size apartment construction project has been presented in the paper to illustrate the proposed concept of using EVM to the reduced extend.

    In the past decade, market globalization has not only been a threat for small and medium-sized enterprises (SMEs), but also an opportunity to expand their activities in many countries (Murphy and al., 1991). In fact, some of SMEs are worldwide leaders in their sectors (Simon, 1990; Entreprise, 1995). Moreover, few of these worldwide SME leaders started businesses directly on an international level (Christensen, 1991; Brush, 1992; McDougall and al., 1994). This suggests that these SMEs use man...

    Full Text Available Modern organizations have raised a need to actively and quickly react to the changes in external business environment, as well as in internal processes considering not only the present situation, but also evaluating possible changes and forecasting the future. Enterprise risk assessment and management, which is strongly related with foreseeing the uncertain future, becomes topical not only scientifically, but also practically seeking to reveal new and unique solutions. Operational risk management in small and medium enterprises, creating the largest part of value added in the whole European Union, demands a separate attention and coordinated decisions and means. The objective of the paper – to analyse the process of enterprise risk management in small and medium-sized enterprises, as well as to propose adequate risk management solutions for these companies. After performing a research, it was found out that small and medium enterprises more than big organizations require a risk management strategy and methodology, need to distinguish activity objectives and events influencing them, and they can efficiently apply a risk portfolio method to manage risk. In small and medium enterprises it is recommended to incorporate a risk management system based on COSO ERM model that can be modified depending on company needs and possibilities, turning it into less formal and structured and easily applicable.

    Sengupta, Arkajyoti; Raghavachari, Krishnan

    2014-10-14

    Accurate modeling of the chemical reactions in many diverse areas such as combustion, photochemistry, or atmospheric chemistry strongly depends on the availability of thermochemical information of the radicals involved. However, accurate thermochemical investigations of radical systems using state of the art composite methods have mostly been restricted to the study of hydrocarbon radicals of modest size. In an alternative approach, systematic error-canceling thermochemical hierarchy of reaction schemes can be applied to yield accurate results for such systems. In this work, we have extended our connectivity-based hierarchy (CBH) method to the investigation of radical systems. We have calibrated our method using a test set of 30 medium sized radicals to evaluate their heats of formation. The CBH-rad30 test set contains radicals containing diverse functional groups as well as cyclic systems. We demonstrate that the sophisticated error-canceling isoatomic scheme (CBH-2) with modest levels of theory is adequate to provide heats of formation accurate to ∼1.5 kcal/mol. Finally, we predict heats of formation of 19 other large and medium sized radicals for which the accuracy of available heats of formation are less well-known.

    Full Text Available Background: Increasing competitiveness in the market, customer expectations related to the shortening of the deadlines and the reduction of prices of products and services force companies to improve the efficiency of internal processes. The integration of planning process is one of possible ways to achieve this aim. The integration of planning processes by the use of SOP model (Sales and Operations Planning is a method to implement this idea. The study allowed to identify ways to implement the process of sales and operations planning in small and medium-sized enterprises. Material and methods: The study was conducted in companies from different industries. The research method was in-depth interviews conducted with managers of companies or persons occupying management positions in the organizational process of implementing sales and operations planning. Results: During the survey, 10 companies were asked about the use of sales and operations planning, its elements and organizational aspects of its development, by the company. Conclusions: The use of sales and operations plan is closely dependent on the size of the company and its localization in the supply chain. Small enterprises are not interested in the integration of the planning process due to the small scale of operations and the centralization of decision-making process. Medium-sized enterprises, due to the increased complexity of the processes of planning, see the benefits of their integration in the SOP model.

    Full Text Available Abstract :Due to their significant role in creation of new jobs, rise in GDP, entrepreneurship and innovation, small and medium-sized enterprises (SMEs are recognized as the the drivers of socio-economic growth, both in developed and developing economies. In Turkey, 99.9 % of all enterprises fall into SME category. Therefore, the significance of SMEs for Turkish economy and society is much higher in Turkey, compared to other emerging and developed countries. Small and medium-sized companies are faced with a number of challenges whereas the problems arising from “poor financial management” are reported as the major causes of business failures in SMEs. Strategic financial management (SFM which is a research area that has attracted the interest of researchers after 2010, is one of the key managerial areas of SMEs, due to its vital role on the survival, growth and performance of SMEs. The purpose of this paper is to analyze the central role of financial management and identify the financial management challenges and practices that influence the organizational performance in Turkish SMEs, from a strategic management perspective. Within the course of this paper, the importance and challenges of SMEs in Turkey are presented in the first section, while the literature on strategic and financial management in SMEs are reviewed in the second part. In the third section, the recent strategic financial management concept, the implications of strategic financial management practices for SMEs in Turkey and the relationships between strategic financial management practices and SME performance, are discussed. Small and medium sized enterprise finance in Turkey is a developing research area, therefore this paper aims to make a significant contribution to the existing literature by analyzing the major challenges at the conduct of financial management in Turkish SMEs and the influence of strategic financial management practices on the performances of small and

  19. Tidal River Elbe - a sediment budget for the grain size fraction of medium sand

    Science.gov (United States)

    Winterscheid, Axel

    2016-04-01

    Human interventions have a historic and ongoing impact on estuarine sediment budgets across many estuaries worldwide. An early inference was the construction of embankments resulting in a constant loss of intertidal flats. Additionally, settlement activities and large scale land use changes in the upstream catchment areas had also an effect on sediment inflow rates. Today, the navigation channels in estuaries have been deepened for larger and more efficient vessels to reach a well-developed infrastructure of harbors and industrial areas often located far inland. In the past few years and just within the North-East Atlantic, the total annual amount of dredged sediments dumped at sea varied from 80 to 130 million tons (OSPAR Commission). In most estuaries across Europe the resulting human impact on the sediment fluxes and morphodynamics is significant. A good understanding of estuarine processes is essential for determining useful and meaningful measures to mitigate negative effects and to improve the current situation. Maintenance dredging and its environmental effects are therefore in the focus of public attention. Against this background, it is the aim of the presentation to identify and therefore to separate the particular effect that maintenance dredging has on sediment fluxes and budgets in the estuarine environment. Case study is the Tidal River Elbe in Germany, and here we set the focus on the grain size fraction of medium sand. In the past, river engineering measures forced the natural dynamics to form a concentrated stream flow along a fixed channel, except at a number of locations where side channels still exist. In addition to that, the main channel was deepened several times. The last deepening was in 1999/2000. The most significant deepening, however, took place from 1957 to 1962. Until then, an erosion-stable layer of marine clay (in German called "Klei") formed a flat bottom along most sections of the main channel. After removal of this layer of

    Full Text Available Small and medium sized enterprises play an essential role in the economy of the Czech Republic as a report of development of small and medium-sized enterprises and its support from 2010 announces. They are the source of development of towns, regions and the state itself. Small and medium-sized enterprises represent 99.84 % of the whole business subjects. Statistic data underline this position- they indicate that small and medium-sized enterprises employ 2/3 employees. Therefore, occupying small and medium-sized enterprises are to be taken as priority.Strategic management on the level of small and medium-sized enterprises is, as number of authors write, diverse. Small enterprises including micro have less access to capital, they have no money for employing specialists in the field, and they solve administration primarily. The aim of this follow-up GAJU project contribution concerned on process analysis of small and medium-sized enterprises is to summarize the gained results from the view of comparison of the level of strategic management in small and medium-sized enterprises.Nowadays, numbers of enterprises are thinking about whether they are able to remain in the market as an established company, they explore the possibility of improving its position. There is a question for small and medium-sized enterprises management- can strategic management be used as an instrument for increasing competitiveness? The results show that SMEs with a clearly defined strategy show better results of financial health (IN99 and ROA than companies without a defined strategy. In terms of business focus, we were able to demonstrate positive relationship between strategy and finance only for companies in the construction industry, on the significance level of 0.05.

    The impact from corporate business activities on the natural environment and society at large has been in focus for quite some time. The focus has often been on corporate environmental sustainability initiatives reflecting industry’s response to concerns expressed by key stakeholders as well...... surveys of industrial companies in Denmark over a number of years. The results indicate a slightly increasing involvement over time, but also that the level of results achieved is lower than the level of initiatives taken. That is, the reactive attitude reported previously still seems to be prevailing....... The results also seem to indicate that the size of the company may have a negative influence in some situations, since smaller companies seems to be better at achieving results compared with medium sized companies....

    Full Text Available The strategic management represents current direction of management. It is applied in all types of enterprises, including small and medium sized ones. Using principles of process management within SMEs has its limitations caused mainly by the size of the enterprise and the related focus on operational management. Other specificities are function accumulation, informal leadership, preference for oral communication before written, etc. Nevertheless, implementation of strategic management can increase competitiveness, reduce costs, improve decision-making, facilitate implementation of the employee motivation system, shorten delivery times, higher quality of customer satisfaction, etc. The aim of this article is to find out how much SME includes principals of the strategic management as their aim.

    Full Text Available It is a common fact, that innovations are the necessary prerequisite of economic development. With regard to the gradual globalization of the world economy, it is obvious that the strategic objectives of every country are directed to own economic wealth which is lead especially by the small and medium-sized enterprises. Due to the fact that these business entities are creating the most of economic growth of every country, the necessity of research, support and development of their innovation potential is obvious. The last and also the least that one could starve for is the building up the barriers to innovativeness of domestic companies, and to decrease competitiveness of the country.In the paper, the authors are focused on the determination of barriers to innovation potential of small and medium-sized enterprises. For this reason, the secondary research of recent studies on innovation barriers has been elaborated. Subsequently, the primary research has been realized on the statistical sample of 173 SMEs. Based on the data analyses, the authors have proved four statistical interactions between innovation potential and factors which stand as barriers to innovation potential development. This paper is based on the confrontation of outcomes of primary research with the secondary research on world-wide perceived barriers to innovations. Data obtained from the primary research had mostly the qualitative and categorical character. Due to this fact, especially Chi-square Test, normalized Pearson coefficient of contingence and Chuprov’s coefficient have been applied.

    Full Text Available Tourism is the world’s largest industry and makes a major contribution to the economies of most developed and developing countries. Tourism as an important socio-economical phenomenon is characterized with distinctly largeness and dynamic development that results with many positive direct as well as indirect economical effects. That is a measure for increasing of possibilities of encouragement of the total economical development through tourism development. Tourism generates income from consumption of goods and services by tourists as well as taxes on businesses in the tourism industry, provides employment in services related to tourism, but also creates jobs in the tertiary sector, generates growth of primary and secondary sectors of the industry as result of multiplicative effect. In this context especially are important small and medium tourism enterprises which dominate in the tourism destinations according to their number, originating a variety of benefits for the tourism destinations by providing direct contact with tourists and by encouraging tourist for spending in a local community. The aim of this paper is to point out the importance of small and mediumsized enterprises in general and especially in the field of tourism for increasing economic development in the national economy with particular reference on the territory of the Republic of Macedonia. In this paper, first will be analyzed the term small and medium - sized enterprises in general and then will be explained their application in the field of tourism with highlighting of their strategic advantages for the tourism destinations and overall economic development of the entire national economy.

    We demonstrate a miniaturized acoustofluidic device composed of a pair of slanted interdigitated transducers (SIDTs) and a polydimethylsiloxane microchannel for achieving size-selective separation and exchange of medium around polystyrene particles in a continuous, label-free, and contactless fashion. The SIDTs, deposited parallel to each other, produce tunable traveling surface acoustic waves (TSAWs) at desired locations, which, in turn, yield an anechoic corner inside the microchannel that is used to selectively deflect particles of choice from their streamlines. The TSAWs with frequency fR originating from the right SIDT and propagating left toward the microchannel normal to the fluid flow direction, laterally deflect larger particles with diameter d1 from the hydrodynamically focused sample fluid that carries other particles as well with diameters d2 and d3, such that d1 > d2 > d3. The deflected particles (d1) are pushed into the top-left corner of the microchannel. Downstream, the TSAWs with frequency fL, such that fL > fR, disseminating from the left SIDT, deflect the medium-sized particles (d2) rightward, leaving behind the larger particles (d1) unaffected in the top-left anechoic corner and the smaller particles (d3) in the middle of the microchannel, thereby achieving particle separation. A particle not present in the anechoic corner could be deflected rightward to realize twice the medium exchange. In this work, the three-way separation of polystyrene particles with diameters of 3, 4.2, and 5 μm and 3, 5, and 7 μm is achieved using two separate devices. Moreover, these devices are used to demonstrate multimedium exchange around polystyrene particles ∼5 μm and 7 μm in diameter.

    Full Text Available The aim of the article is an attempt to ground the concept of transformation of national institutional environment as the prerequisites for forming of prosperous class of small and medium-sized enterprises. Institutional analysis considers the interaction on the level of individuals and divides a market transaction into transactions (institutional agreements, estimating their value with the help of transaction costs. We conducted a systematization of the notion that brings the institutional environment to the aggregate of norms, regulations, agreements, rules of the game. For the quality assessment of institutional environment on the macrolevel, direct indicators of its assessment were used – quality indexes in international ratings and activities of specialized institutional researches. Practical significance. In the result the quality of the institutional environment of the assessment of The Global Competitiveness Index is extremely low and needs a systematic increase. Values of indicators of a pillar “Institutions” of The Global Competitiveness Index should be a guiding line for development and introduction of state economic policy. An important line of investigations of development mechanism’s improvement and regulatory policy’s conducting is the institutional environment conception that combines the notions of institute, institutional agreements and transaction costs. A model of institutional environment allows determining of the regulatory policy as a policy that changes elements of institutional environment – institutions, displays in changes of transaction costs. It is grounded that a state apparatus consciously sets as an object the increase of socio-economic role of the entrepreneurship through the creating of favourable conditions of its functioning; a way of this object’s achievement is the regulatory policy, efficiency criterion of which is the improving of national institutional environment’s quality that is

    Full Text Available Along with marketing, small and medium enterprises (SMEs are commonly associated in literature with relationship marketing which results in marketing networks. This paper examines the specific characteristics that differentiate large companies from small and medium-sized enterprises, and the reasons that prevent SMEs from engaging in traditional marketing within the scope of marketing mix. The paper also shows that the key characteristic which distinguishes small from large companies is a prominent role of owner/managers. The owner/manager affects marketing of SMEs by creating his or her own personal networks with stakeholders in the environment, and considers it an important strategic focus and a factor that increases the performance of marketing decision-making. After a thorough review of secondary data sources this paper examines relationship marketing as a marketing framework for SMEs and, finally, proves that relationship marketing is more appropriate for SMEs than are traditional marketing concepts, that relationship marketing and network marketing create an important framework for SMEs and that there is a link between relationship marketing, personal networks and SMEs.

    Full Text Available Taxation provides a predictable and stable flow of revenue to finance development objectives. This is important in a country like Cameroon that has serious challenges with meeting its development objectives. Small and medium enterprises (SMEs are significant for economic growth in the country, contributing as much as about 22 percent of the gross domestic product. SMEs generate taxable incomes. They also collect employment and value added taxes on behalf of the government. Taxation, however, imposes high cost to small businesses. SMEs are less tax compliant in comparison to large businesses. SMEs are considered the ‘hard to tax group from the informal sector.’ As such, the literature suggests that only a fraction of their taxable incomes is reported to tax authorities. Against this background, factors that correlate with tax compliance of 575 small and medium size companies in Cameroon are discussed from a survey of companies in the manufacturing and wholesale sectors. High registration cost and time-consuming processes promote tax non-compliance. The perception that tax system is corrupt discourages registration and filing compliance. When there are too many compliance hurdles, the probability of filing compliance is reduced. However, a fair and static system encourages filing and registration compliance. A clear and consistent tax system promotes filing compliance. Authorities that understand their responsibilities and are willing to respond to enquiries during the registration process promote tax compliance in general.

    2013-01-01

    Full Text Available The paper investigates small-scale effects on the Rayleigh-type surface wave propagation in an isotopic elastic half-space upon laser irradiation. Based on Eringen’s theory of nonlocal continuum mechanics, the basic equations of wave motion and laser-induced atomic defect dynamics are derived. Dispersion equation that governs the Rayleigh surface waves in the considered medium is derived and analyzed. Explicit expressions for phase velocity and attenuation (amplification coefficients which characterize surface waves are obtained. It is shown that if the generation rate is above the critical value, due to concentration-elastic instability, nanometer sized ordered concentration-strain structures on the surface or volume of solids arise. The spatial scale of these structures is proportional to the characteristic length of defect-atom interaction and increases with the increase of the temperature of the medium. The critical value of the pump parameter is directly proportional to recombination rate and inversely proportional to deformational potentials of defects.

    Full Text Available Small and medium enterprises (SME are the engine of the European economy. They are an essential source of jobs, create entrepreneurial spirit and innovation in the EU and are thus crucial for fostering competitiveness and employment. In the enlarged European Union of 27 countries, some 20 million SMEs provide around 75 million jobs and represent 99 % of all enterprises. However, they are often confronted with market imperfections. SMEs frequently have difficulties in obtaining capital or credit, particularly in the early start–up phase. Their limited resources may also restrict access to new technology or innovation. It is therefore necessary to monitor the development of SMEs in individual EU countries and highlighting their problems and mainly to their importance.During the recent period of time there have been many researchers from the FBE Mendel University in Brno, who focused on the analysis of the small and medium-sized enterprise, e.g. Bohušová (2007; Chládková (2009; Nerudová a Bohušová (2008; Kubíčková a Peprný (2006; Zrůst a Pyšný (2008.

    2011-08-01

    During the last years there has been a growing need of developing innovative tools that can help small to medium sized enterprises to predict business failure as well as financial crisis. In this study we present a novel hybrid intelligent system aimed at monitoring the modus operandi of the companies and predicting possible failures. This system is implemented by means of a neural-based multi-agent system that models the different actors of the companies as agents. The core of the multi-agent system is a type of agent that incorporates a case-based reasoning system and automates the business control process and failure prediction. The stages of the case-based reasoning system are implemented by means of web services: the retrieval stage uses an innovative weighted voting summarization of self-organizing maps ensembles-based method and the reuse stage is implemented by means of a radial basis function neural network. An initial prototype was developed and the results obtained related to small and medium enterprises in a real scenario are presented.

    Knowledge management has now also reached the energy economy, as first branch-specific seminars show. This awakening interest is very much to be welcomed, although until now it has been more the representatives of large energy companies who have made themselves heard. Public utilities, which as a rule are subsumed under the category ''small and medium sized company'', have other possibilities as well as limitations than large corporations when it comes to knowledge management. The present article explains what knowledge management is and how public utilities and regional supply companies can identify and make practical use of opportunities available to them through knowledge management while giving due consideration to their structural characteristics.

    The construction of a prototype Schwarzschild-Couder telescope (pSCT) started in early June 2015 at the Fred Lawrence Whipple Observatory in Southern Arizona, as a candidate medium-sized telescope for the Cherenkov Telescope Array (CTA). Compared to current Davies-Cotton telescopes, this novel instrument with an aplanatic two-mirror optical system will offer a wider field-of-view and improved angular resolution. In addition, the reduced plate scale of the camera allows the use of highly-integrated photon detectors such as silicon photo multipliers. As part of CTA, this design has the potential to greatly improve the performance of the next generation ground-based observatory for very high-energy (E>60 GeV) gamma-ray astronomy. In this contribution we present the design and performance of both optical and alignment systems of the pSCT.

    2017-03-01

      Urban water systems (UWSs) are challenged by the sustainability perspective. Certain limitations of the sustainability of centralized UWSs and decentralized household level wastewater treatments can be overcome by managing UWSs at an intermediate scale, referred to as small to medium sized UWSs (SMUWSs). SMUWSs are different from large UWSs, mainly in terms of smaller infrastructure, data limitation, smaller service area, and institutional limitations. Moreover, sustainability assessment systems to evaluate the sustainability of an entire UWS are very limited and confined only to large UWSs. This research addressed the gap and has developed a set of 38 applied sustainability performance indicators (SPIs) by using fuzzy-Elimination and Choice Translating Reality (ELECTRE) I outranking method to assess the sustainability of SMUWSs. The developed set of SPIs can be applied to existing and new SMUWSs and also provides a flexibility to include additional SPIs in the future based on the same selection criteria.

    Cellary, Wojciech

    Networked Virtual Organizations (NVOs) are a right answer to challenges of globalized, diversified, and dynamic contemporary economy. NVOs need more than e-trade and outsourcing, namely, they need out-tasking and e-collaboration. To out-task, but retain control on the way a task is performed by an external partner, two integrations are required: (1) integration of computer management systems of enterprises cooperating within an NVO; and (2) integration of cooperating representatives of NVO member enterprises into a virtual team. NVOs provide a particular chance to Small and Medium size Enterprises (SMEs) to find their place on global markets and to play a significant role on them. Requirements for SMEs to be able to successfully join an NVO are analyzed in the paper.

  10. Improved Cost Management at Small and Medium Sized Road Transport Companies: Case Hungary

    Directory of Open Access Journals (Sweden)

    Zoltan Bokor

    2015-10-01

    Full Text Available Small and medium sized road freight transport companies located in Hungary are facing strong competition on the logistics market. An advanced cost management system supporting decisions on capacity allocations or pricing may be a competitive advantage for them and indirectly for the whole economy as well. Still, they generally apply simple, traditional cost calculation regimes, potentially sufficient in case of a homogeneous service portfolio. Nevertheless, road haulage companies with heterogeneous service structures may witness information distortions when using traditional costing methods. So it might be recommended for them to introduce better costing principles. To support an improved transport costing, a multi-level full cost allocation model has been set up and tested in this paper. The research results have pointed out that such a methodological development accompanied by the extension of the data collection mechanism can contribute to making the cost management systems of road freight transport companies more effective.

    Full Text Available Small and Medium-sized Enterprises (SMEs contribute highly to the gross domestic product, reduction in unemployment, wealth creation and improvement in the quality of life. Due to technology and globalisation, SMEs now compete with enterprises beyond the borders of their country. To survive in this global competitive business environment, SMEs seek for tools that offer competitive advantage. Competitive Intelligence (CI provides competitive advantage to enterprises that practice it. While CI practice has been widely research for larger enterprises, there is lack of research on CI practice pertaining to SMEs. This research establishes tools used by SMEs in CI practice. The research was quantitative in nature and a self-administered questionnaire was used to collected data from owners/managers of SMEs

    This study examines the risk perception of decision-makers in small and medium sized enterprises (SMEs) and the factors underlying these perceptions in the process of internationalization of their firms. While risk perception has been identified as a potential predictor variable...... in internationalisation research, very little work has been done exploring the factors and processes that shape decision-makers’ perception of risk. A qualitative interview-based approach was adopted by collecting data from thirty-two Danish SMEs operating in four different industries. Findings suggest that while risk...... awareness exists, decision-makers do not perceive internationalisation as risky behaviour. Findings highlight the importance of decision-makers’ background, including cognitive and psychological characteristics, such as self-efficacy and locus of control, and their experiences in explaining risk perceptions...

    Critical gaps in our understanding of the distributions, interactions, life histories and preferred habitats of large and medium-size pelagic fishes severely constrain the implementation of ecosystem-based, spatially structured fisheries management approaches. In particular, spawning distributions and the environmental characteristics associated with the early life stages are poorly documented. In this study, we consider the diversity, assemblages, and associated habitat of the larvae of large and medium-sized pelagic species collected during 2 years of monthly surveys across the Straits of Florida. In total, 36 taxa and 14,295 individuals were collected, with the highest diversity occurring during the summer and in the western, frontal region of the Florida Current. Only a few species (e.g. Thunnus obesus, T. alalunga, Tetrapturus pfluegeri) considered for this study were absent. Small scombrids (e.g. T. atlanticus, Katsuwonus pelamis, Auxis spp.) and gempylids dominated the catch and were orders of magnitude more abundant than many of the rare species (e.g. Thunnus thynnus,Kajikia albida). Both constrained (CCA) and unconstrained (NMDS) multivariate analyses revealed a number of species groupings including: (1) a summer Florida edge assemblage (e.g. Auxis spp., Euthynnus alleterattus, Istiophorus platypterus); (2) a summer offshore assemblage (e.g. Makaira nigricans, T. atlanticus, Ruvettus pretiosus, Lampris guttatus); (3) an ubiquitous assemblage (e.g. K. pelamis, Coryphaena hippurus, Xiphias gladius); and (4) a spring/winter assemblage that was widely dispersed in space (e.g. trachipterids). The primary environmental factors associated with these assemblages were sea-surface temperature (highest in summer-early fall), day length (highest in early summer), thermocline depth (shallowest on the Florida side) and fluorescence (highest on the Florida side). Overall, the results of this study provide insights into how a remarkable diversity of pelagic species

    Full Text Available Non-metallic inclusions found in steel can affect its performance characteristics. Their impact depends not only on their quality, but also, among others, on their size and distribution in the steel volume. The literature mainly describes the results of tests on hard steels, particularly bearing steels. The amount of non-metallic inclusions found in steel with a medium carbon content melted under industrial conditions is rarely presented in the literature. The tested steel was melted in an electric arc furnace and then desulfurized and argonrefined. Seven typical industrial melts were analyzed, in which ca. 75% secondary raw materials were used. The amount of non-metallic inclusions was determined by optical and extraction methods. The test results are presented using stereometric indices. Inclusions are characterized by measuring ranges. The chemical composition of steel and contents of inclusions in every melts are presented. The results are shown in graphical form. The presented analysis of the tests results on the amount and size of non-metallic inclusions can be used to assess them operational strength and durability of steel melted and refined in the desulfurization and argon refining processes.

    A bench to measure the magnetic field of small to-medium-sized magnets with high precision was built. It uses a small-sized head with three orthogonal Hall probes, supported on a long pole at continuous movement during measurement. The head is calibrated in three dimensions by rotation over the full solid angle in a special device. From 0 to 2.5 T, the precision is ±0.2 mT in all components. The spatial range is 1 × 1 × 2 m with precision of ±0.02 mm. The bench and its controls are lightweight and easy to transport. The head can penetrate through small apertures and measure as close as 0.5 mm from the surface of a magnet. The bench can scan complicated grids in Cartesian or cylindrical coordinates, steered by a simple text file on an accompanying PC. The raw data is online converted to magnetic units and stored in a text file.

    Full Text Available On existing conditions on global market (almost identical quality, almost identical purchasing values companies have to definite the total rating of importance of evaluative criteria. In post-crisis period the problem of suppliers’ evaluation is one of the biggest, because companies had to use all resources and all possibilities to develop their own business. Many authors wrote about collaborative planning and warehousing as one of possibilities to optimization work inside supply chain. For this paper define small and medium-sized enterprises (SME as enterprises with the size of maximum 250 em­ployers. In literature was read we couldn’t find information about own system of suppliers evaluation for small and medium-sized enterprises. SME can have some different types of business and in this case need the universal system of eva­lua­tion. The research of this paper is oriented on small and medium-sized enterprises with different types of business. The new theoretical universal method of calculation for evaluation existing suppliers for small and medium-sized enterprises will present in this paper. This theoretical method is based on average values. This method includes traditional evaluative criteria (quality, delivery time and other (mobility of supplier, possibilities of new level of partnership. This method of evaluation can not be used for continual manufacture. New method can improve the total evaluation of supplier in small and medium-sized enterprises.

    Full Text Available The nucleus accumbens is a limbic nucleus, representing part of the striatum body, and together with the caudate nucleus and putamen, it lies on the septum. The aim of this study was to examine morphological sexual dimorphism in spine density and also to undertake an immunohistochemical study of expression for estrogen and progesterone receptors in the medium-sized neurons in the nucleus accumbens. The research was conducted on twenty human brains of persons of both sexes, between the age of 20-75 years. The Golgi method was applied to determine the types and subtypes of neurons, morphologies of soma, dendrites and axons, as well as the relations between the cells and glial elements. The following were quantitatively examined: the maximum diameter of the neurons, the minimal diameter of the neurons, and the total length of the dendrites. The expression of receptors for estrogen and progesterone, their distribution and intensity were defined immunohistochemically. The parameters of the bodies of neurons in the shell and core of the nucleus accumbens were studied in both men and women. No statistically significant differences were found. Examination of the spine density showed statistical significance in terms of a higher density of spines in women. Immunohistochemically, in the female brain estrogen expression is diffusely spread in a large number of neurons; it is extra nuclear, of granular appearance and high intensity. In the male brain, expression of estrogen is visible and distributed over about one half of different types of neurons; it is extra nuclear, of granular appearance, mostly of middle and low staining intensity. Expression of progesterone in the female brain was very discreet and on a very small number of neurons; it was extra nuclear and with a weak staining intensity. Expression of progesterone in the male brain was distributed on a small number of neurons. It had a granular appearance, it was extra nuclear, with a very low

    Full Text Available Purpose: The present paper aims at developing an effective framework including all the components necessary for implementing lean production properly in Small and Medium-sized Enterprises. Design/methodology/approach: The paper begins with the review of the main existing framework of lean implementation in order to highlight shortcomings in the literature through a lack of suitable framework for small companies. To overcome this literature gap, data of successful initiatives of lean implementation were collected based on a multiple case study approach. These initiatives has been juxtaposed in order to develop a new, practical and effective framework that includes all the components (process, tools, success factors that are necessary to implement lean in Small and Medium-sized Enterprises. Findings: The proposed framework presents many significant contributions: First, it provides an overcoming for the limitations of the existing frameworks by proposing for consultants, researchers and organizations an effective framework for lean implementation in SMEs that allows SMEs to benefit from competitive advantages  gained by lean. Second, it brings together a set of the more essential and critical elements of lean implementation commonly used by SMEs and derived from the practical experiences of them in lean implementation. Finally, it highlights the successful experiences of small companies in implementing lean programs and then proves that lean can give a relevant results even for SMEs. Research limitations/implications: The proposed framework presents a number of limitations and still evokes extension for further researches: Although it was derived from practical experiences of SMEs, the proposed framework is not supported by practical implementation. On the other hand and even though the elements in the proposed framework from the practical experiences of four SMEs, the identified elements need to be generalized and enriching by conducting

    Full Text Available Urban climate is the result of both atmospheric and geographic factors affecting a region, as well as the morphology, structures and human activities in a city. Urban vegetation in particular affects this climate at a local scale and provides many other social, economic and ecological benefits. Thus, it is important to explore the effects of different green areas used for urban and periurban agriculture and forestry activities (UPAF on daily atmospheric temperature and the required degrees of cooling or refrigerating temperature. Comfort temperatures were defined using a range 18-24°C and analyzed using actual measured as well as forecasted temperatures using a future scenario. Actual temperatures were recorded from September 2013 to August 2014 using digital sensors across eight sites in Rosario, Argentina: three in the central core with no vegetation, one in the central core with street trees, one in an urban agriculture site, one in a public park and two in periurban agricultural areas. Results show that air temperature in the central core with no vegetation were higher than those in other sites with vegetation during day and night, with the exception of the temperatures measured at the central core site with street trees. Findings also show that temperature effects in urban agricultural gardens of approximately 0.2 ha were similar to those of gardens and public parks 2-3 ha in size. Three UPAF types were classified according to cooling degree days, which decreased in order from (1 central core with no trees; (2 central core with street trees and public parks; and (3 urban and periurban agriculture areas. Conversely, the opposite trends for heating degree days were found. Results from this study can be used for integrating UPAF measures into climate change mitigation and urban planning policies in medium-sized cities in the developing world.

    Full Text Available Main directions of development of small and medium-sized enterprises in Ukrainian agriculture are examined. It is determined that entrepreneurship in agrarian sector is a driving force behind the development of agriculture, as these activities contributes to the production of quality agricultural products that satisfies the needs of society, food security, independence and improves the living standards of rural population. Potential customers of small parties of harvest in Ukrainian grain market are analyzed. The ways of mutually beneficial cooperation between Ukrainian farmers and entrepreneurs are proved. The study of foreign experience has proven that strengthening the competitiveness of Ukrainian agricultural products in the context of globalization is possible on the basis of mutually beneficial cooperation of Ukrainian farmers and entrepreneurs, where recent purchase of output at market prices for the purpose of resale or creation of agricultural cooperatives, such form of economy in agrarian relations that combines a balanced economic, social and environmental components. In particular in paper is shown that sustainable economic management provide only forms of economy that take into account the socioeconomic and geophysical specifics of agriculture, particularities of agricultural labor and methods of management. The most common among these forms are farmers.

    Full Text Available The market economy has reduced the number of large enterprises and has determinated the emergence ofa special class like small and medium-sized enterprises. Those companies play a special role in the nationaleconomy, especially through the fact that attract about 65% of employees in Romania, makes significantinvestments, takes approximately 30% of gross value added in the national economy, operates mainly in servicesactivity, are flexible, concerned with development and have the ability to adopt new technologies. The SMEsector has been affected by the crisis, but not in the same measure as large enterprises. This fact is demonstratedby the economic and financial indicators that I have analised, in 2011 SME beeing able to overcome the crisisand to achieve higher performance than in the years before crisis. The SME sector is considered the most activesector of the modern economy, plays a important role in the economic structure of our country, helping to ensureeconomic and social development as it is shown by the strong bond that exist between the GVA in SME sectorand total GVA added to the national economy, demonstrated in the calculations that I have made in this study.

    Waste prevention is a principle means of achieving the goals of waste management and a key element for developing sustainable economies. Small and medium sized enterprises (SMEs) contribute substantially to environmental degradation, often not even being aware of their environmental effects. Therefore, several initiatives have been launched in Austria aimed at supporting waste prevention measures on the level of SMEs. To promote the most efficient projects, they have to be evaluated with respect to their contribution to the goals of waste management. It is the aim of this paper to develop a methodology for evaluating waste prevention measures in SMEs based on their goal orientation. At first, conceptual problems of defining and delineating waste prevention activities are briefly discussed. Then an approach to evaluate waste prevention activities with respect to their environmental performance is presented and benchmarks which allow for an efficient use of the available funds are developed. Finally the evaluation method is applied to a number of former projects and the calculated results are analysed with respect to shortcomings and limitations of the model. It is found that the developed methodology can provide a tool for a more objective and comprehensible evaluation of waste prevention measures.

    This paper reports the experimental testing for centrifugal pump for fisherman ship, manufactured by small and medium sized enterprises in Central Java Province, Indonesia. The research covers material analysis, component observation, endurance and vibration test. Six centrifugal pumps are tested and three main pump components are discussed: shaft, bearings and seals. The results show that the material of the shaft is predicted to support and transmit the load from the engine to impeller. The problem found in the tolerance and geometry accuracy of the shaft which causes difficulties during assembling process, excessive wear and leakage during testing. From the endurance and vibration test, the ball bearings fail and lock the shaft due to the fatigue on the rolling elements and raceways. The oil seal and water seal also fail in maintaining the oil and water in the chamber and induce the unlubricated system for the ball bearings. Some suggestions are delivered to improve the product quality of the centrifugal pump. A good quality of the centrifugal pump for fishermen ship and long life span is expected to be produced by local SMEs to win the free trade competition in the Indonesian market.

    Full Text Available The market for enterprise systems (ESs continues to grow as business becomes increasingly global and competitive. Increasingly, the market focus for ES vendors is on small businesses. The purpose of this study is to provide a unique ES vendor/consultant perspective on (a the business benefits small and medium-sized enterprises (SMEs expect from their ES investment and (b to examine current practices of ES implementation in SMEs through a conceptual framework that considers the organisational, process and strategic context of the implementation. This study does so with interview data collected from ES vendors, ES consultants and IT research firms, who are the key players in the New Zealand ES industry. A distinctive contribution of this research is the vendor/consultant perspective as the unit of analysis, rather than the SME perspective commonly used in similar research. The vendor/consultant perspective offers a comprehensive viewpoint that extends across numerous SMEs in a variety of industries. Findings from interviews with these professionals indicate that although many ES implementations are several years old now, SMEs have only recently started tracking benefits through analytical processes in expectation to realise business value from their ES investment. The results also identify how ES implementation practices are adapting to be more suitable to the SME sector, an important market for ES vendors given the saturation of the large enterprise market for ES implementation.

    Total chemical synthesis provides a unique approach for the access to uncontaminated, monodisperse, and more importantly, post-translationally modified membrane proteins. In the present study we report a practical procedure for expedient and cost-effective synthesis of small to medium-sized membrane proteins in multimilligram scale through the use of automated Fmoc chemistry. The key finding of our study is that after the attachment of a removable arginine-tagged backbone modification group, the membrane protein segments behave almost the same as ordinary water-soluble peptides in terms of Fmoc solid-phase synthesis, ligation, purification, and mass spectrometry characterization. The efficiency and practicality of the new method is demonstrated by the successful preparation of Ser64-phosphorylated M2 proton channel from influenza A virus and the membrane-embedded domain of an inward rectifier K(+) channel protein Kir5.1. Functional characterizations of these chemically synthesized membrane proteins indicate that they provide useful and otherwise-difficult-to-access materials for biochemistry and biophysics studies.

    Full Text Available Information Technology (IT adoption is an important field of study in a number of areas, which include small and medium-sized enterprises (SMEs. Due to the numerous advantages of IT, SMEs are trying to adopt IT applications to support their businesses. IT adoption by SMEs differs from larger organizations because of their specific characteristics, such as resources constraints. Therefore, this research aims to provide a better and clearer understanding of IT adoption within SMEs by reviewing and analyzing current IT literature. In this research, the review of literature includes theories, perspectives, empirical research and case studies related to IT adoption, in particular within SMEs from various databases such as Business Premier, Science Direct, JStor, Emerald Insight and Springer Link. The proposed model of effective IT adoption is believed to provide managers, vendors, consultants and governments with a practical synopsis of the IT adoption process in SMEs, which will in turn assist them to be successful with IT institutionalization within these businesses.

    CTA (Cherenkov Telescope Array) will be the largest ground-based gamma-ray observatory ever built. Two arrays are foreseen to be build, one in the Southern and one in the Northern hemisphere. A prototype for the Medium Size Telescope (MST) type (diameter: 12 m) will be installed in Berlin in early 2012. This MST prototype will be composed of the mechanical structure, drive system and mirror facets with an active mirror control system. The stability of the mechanical structure will be investigated with CCD cameras and a weather station. Furthermore the ALMA Common Software (ACS) distributed control framework will used as readout and control system for the MST, allowing to evaluate the software with the future use for the whole CTA array in mind. The design of the control software is following the concepts and tools under evaluation within the CTA consortium, like the use of a UML based code generation framework for ACS component modeling, and the use of OPC Unified Architecture (OPC UA) for hardware access. In this contribution the progress in the implementation of the control system for this CTA prototype telescope is described.

    Full Text Available Background: New value innovations are organically ingrained and complementary to the process of knowledge management. However, epistemological trends highlight only limited studies to have explored how the effectiveness of knowledge management leverages new value innovations.Objectives: This research evaluates how the effectiveness of the small- and medium-sized enterprises’ (SMEs knowledge management systems enhance new value innovations so as to identify the major paradoxes and a business model that coherently integrates knowledge management with new value innovations.Method: Using a qualitative research method, semi-structured interviews were used to explore the opinions of 20 purposively sampled managers from 20 SMEs on how knowledge management edifies new value innovations.Results: A strong culture of information utilisation was found to enhance relevant analysis and identification of new gaps in the markets that must be filled through new value innovations or modifications of the existing products. However, poor culture of knowledge utilisation, cost of knowledge management and the often poorly functional business information systems were still reiterated as major paradoxes hampering effective knowledge management as one of the determinants of new value innovations.Conclusion: The study concluded with a model highlighting a continuum of knowledge management–new value innovation pillars like a strong culture of information utilisation, and encouragement of creativity that the executives must consider to create an effective knowledge management foundation that subsequently leverages the overall effectiveness of new value innovations.

    Full Text Available Understanding the transmission dynamics of infectious diseases is important to allow for improvements of control measures. To investigate the spatiotemporal pattern of an epidemic dengue occurred at a medium-sized city in the Northeast Region of Brazil in 2009, we conducted an ecological study of the notified dengue cases georeferenced according to epidemiological week (EW and home address. Kernel density estimation and space-time interaction were analysed using the Knox method. The evolution of the epidemic was analysed using an animated projection technique. The dengue incidence was 6.918.7/100,000 inhabitants; the peak of the epidemic occurred from 8 February-1 March, EWs 6-9 (828.7/100,000 inhabitants. There were cases throughout the city and was identified space-time interaction. Three epicenters were responsible for spreading the disease in an expansion and relocation diffusion pattern. If the health services could detect in real time the epicenters and apply nimbly control measures, may possibly reduce the magnitude of dengue epidemics.

    Multidisciplinary care is a key enabler in the provision of high quality care for cancer patients. Despite compelling evidence supporting their benefit to patients and for providers, multidisciplinary cancer conferences (MCC) are not universally occurring. Team composition of MCC reflects the multidisciplinary nature of the body. Lack of nursing input can have a negative impact on team decision making. The objective of this study was to evaluate multidisciplinary care and adherence to national recommendations at a medium-sized hospital through a clinical audit of cancer conferences and clinical records. A total of 77 multidisciplinary cancer conferences were visited and 496 electronic health records were reviewed. The regularity of meetings and multidisciplinary attendance were evaluated. Each electronic health record was checked to verify documented prospective discussion before any treatment was started. Nine multidisciplinary teams meet on a weekly or biweekly basis at the hospital with an average number of ten people and six different specialties represented. Average duration of meetings was 46.8 min. Though most patients (64.5%) were discussed at some point at the relevant cancer conference, only 40% had a documented multidisciplinary team discussion prior to the first treatment. Pathological stage (pTNM) was documented in 53.6% of clinical records. Nursing representatives should be included as usual attendees at cancer conferences. Prospective discussion of all cancer cases should be encouraged. Use of checklists and systematic collection of key information, specifically cancer staging, could improve clinical documentation in the electronic clinical record.

    Full Text Available This research investigates the determinants of the capital structure of small and medium enterprises (SMEs using a unique database that includes over 19,000 Brazilian firms and spans 13 years of data. The econometric analysis employs the System Generalized Method of Moments estimator (GMM-Sys and two strong results emerge: (a profitability is negatively related to leverage, and (b asset growth is positively related to leverage. Both results are consistent with the pecking order theory of capital structure and suggest that SMEs tend to finance their expansion with debt only after exhausting their internal resources. Additionally, we find weaker evidence for the following: (a size is positively related to leverage, which can be interpreted as evidence that larger firms have more access to credit markets; (b riskier SMEs tend to be less financially leveraged, consistent with the bankruptcy cost arguments from trade-off theories; and (c the age of the firm is negatively related to financial leverage, suggesting that older SMEs may be slightly more conservative in their financing choices. Finally, the magnitude of the coefficient of lagged leverage shows the high persistence of this variable and is compatible with the hypothesis that SMEs adjust their debt/equity ratio towards a target value, although at a low speed.

    Energy Analysis and Diagnostic Centers (EADCs) provided energy-conserving and cost saving assistance in 339 small and medium-size manufacturing plants nationwide during 1988-89. This report presents the results of what was recommended to those manufacturers, the record of what was implemented by them, and an analysis of the financial rewards gained by them. It also includes an accounting of the financial returns to the federal government, derived from taxes upon the cost savings, or incremental income, of the manufacturers who implement the EADCs` recommendations. EADCs collect implementation data within a year of the energy audit, and for these results that time period extended through 1990. The EADCs are located at accredited engineering departments of universities and staffed by faculty and students. At present there are 18 EADCs serving manufacturers in 37 states; of these, two were established as a result of the 1989 competition, and five more were chosen competitively in 1990. Most of the results in this report were generated by 11 EADCs (named in the Appendix); two others withdrew voluntarily after completing only 10 energy audits during 1988-89. Primary responsibility for selecting, training, evaluating, and managing the EADCs belongs to the Industrial Technology and Energy Management (ITEM) division of University City Science Center (UCSC). The Department of Energy`s Office of Industrial Technologies sponsors the EADC program through an agreement with UCSC.

    An electrochromic device based on a five layer coating deposited on a glass sheet was produced. The layers were all obtained by physical vapour deposition in the same vacuum environment, using a commercial apparatus capable of producing thin films on large area substrates. Small (50 x 50 mm{sup 2}) and medium (300 x 300 mm{sup 2}) size specimens were prepared for preliminary study, to establish the electrochemical and optical performances of the device. Electrochemical measurements were performed on each active material, as well as on the whole specimens, in order to relate electrochemical properties to process conditions. Also, luminous and solar parameters were obtained from (near) normal incidence spectrophotometry in both the bleached and coloured states, to confirm the values used in the design phase of the electrochromic device. One of the specimens was also submitted to variable angle photometric and radiometric measurements, using an integrating sphere. This data was then used to evaluate the room luminance distribution and energy loads using a building simulation code. (author)

  1. Signaling from the cytoplasm to the nucleus in striatal medium-sized spiny neurons

    Full Text Available Striatal medium-sized spiny neurons (MSNs receive massive glutamate inputs from the cerebral cortex and thalamus and are a major target of dopamine projections. Interaction between glutamate and dopamine signaling is crucial for the control of movement and reward-driven learning, and its alterations are implicated in several neuropsychiatric disorders including Parkinson’s disease and drug addiction. Long-lasting forms of synaptic plasticity are thought to depend on transcription of gene products that alter the structure and/or function of neurons. Although multiple signal transduction pathways regulate transcription, little is known about signal transmission between the cytoplasm and the nucleus of striatal neurons and its regulation. Here we review the current knowledge of the signaling cascades that target the nucleus of MSNs, most of which are activated by cAMP and/or Ca2+. We outline the mechanisms by which signals originating at the plasma membrane and amplified in the cytoplasm are relayed to the nucleus, through the regulation of several protein kinases and phosphatases and transport through the nuclear pore. We also summarize the identified mechanisms of transcription regulation and chromatin remodeling in MSNs that appear to be important for behavioral adaptations, and discuss their relationships with epigenetic regulation.

    Little is known about the potential for overexposure to respirable quartz in farming, in most parts of the world. To measure respirable dust and quartz exposure of tractor operators on two medium-sized dry climate farms. This is a descriptive cross-sectional study of dust exposure of four tractor operators. Farms were selected by convenience sampling. The MDHS 14/3 and FTIR MDHS 101 HSE methods were used to measure dust and to analyze the mass of quartz in dust, respectively. Seventy respirable dust measurements were done. Respirable dust and quartz ranged from 0·01 to 2·88 and 0·001 to 0·30 mg/m(3), respectively. All operators had at least one respirable quartz exposure above 0·1 mg/m(3). Only 17% of respirable quartz concentrations were lower than the ACGIH TLV of 0·025 mg/m(3). The potential for overexposure to respirable quartz was demonstrated. There was a great deal of exposure variability on these farms which has implications for sampling strategies for dust in farming.

  3. Fully Flexible Docking of Medium Sized Ligand Libraries with RosettaLigand.

    Full Text Available RosettaLigand has been successfully used to predict binding poses in protein-small molecule complexes. However, the RosettaLigand docking protocol is comparatively slow in identifying an initial starting pose for the small molecule (ligand making it unfeasible for use in virtual High Throughput Screening (vHTS. To overcome this limitation, we developed a new sampling approach for placing the ligand in the protein binding site during the initial 'low-resolution' docking step. It combines the translational and rotational adjustments to the ligand pose in a single transformation step. The new algorithm is both more accurate and more time-efficient. The docking success rate is improved by 10-15% in a benchmark set of 43 protein/ligand complexes, reducing the number of models that typically need to be generated from 1000 to 150. The average time to generate a model is reduced from 50 seconds to 10 seconds. As a result we observe an effective 30-fold speed increase, making RosettaLigand appropriate for docking medium sized ligand libraries. We demonstrate that this improved initial placement of the ligand is critical for successful prediction of an accurate binding position in the 'high-resolution' full atom refinement step.

    Full Text Available The challenges that business face in sustaining competitive advantage in the corporate world have become a major concern. Businesses are adopting cutting-edge technologies and best practices to cope with rapid, global changes. Various business functions are being reengineered for this purpose. Accounting functions play an important role in helping businesses to maintain competitive advantage. However, some small and medium-sized enterprises (SMEs face problems handling fundamental accounting functions. This is predominantly because of their lack of expertise; accounting functions require not only knowledge of generally accepted accounting rules or tax regulations but also the expertise needed to apply the rules in a given business environment (Everaert, Sarens and Rommel, 2006. This paper offers some insight on the outsourcing of accounting functions as there is paucity of data in this area in the context of Malaysia. Essentially, it presents empirical evidence regarding Malaysian SMEs' accounting outsourcing practices. A survey of SMEs was conducted to identify the overall outsourcing landscape as it relates to accounting and third-party organisations. The factors that contribute to the decision to outsource accounting functions are analysed. The study reveals a significant relationship between outsourcing accounting functions and two contributing factors, risks and operation management.

    Full Text Available Risk is inherent in all business functions and in every kind of activity. Small and medium-sized enterprises (SMEs are particularly vulnerable to continuously daily internal and external undesirable events that adversely affect business performance. To deal with many risk determinants effectively, SMEs need a systemic method of approach to risk management. One of the factors of company risk management approach is gender of the owners or top executives. Especially from a managerial perspective, the link between risk-taking and gender has been examined through a wide range of approaches, such as entrepreneurial orientation and leadership related literatures. Some researchers point that male SME owners appear to show a greater risk appetite than female SME owners. The leading question in the undertaken research was to determine whether the gender of the firm's owners or top executives are reflected in the approach to risk management. The focal point of the research is identification of differences in risk taking and risk management in Polish SMEs companies from a gender perspective.

    Full Text Available SMEs sector plays a vital role in modern economies. Therefore, the interest in its functioning among economists is in fact quite natural. This article is a part of a current research on regional factors contributing to the development of enterprises in this category. The first section examines earlier studies in this field conducted globally and in Poland. According to them, many elements enable the SME’s development. It is not surprisingly that the specified set of pro-growth factors does not exists. Next section describes the results of the author’s own studies in the fields. These studies relate to regional factors contributing to the efficiency growth of micro, small and medium-sized enterprises in Poland. Data used in the study was collected from GUS[1] and EUROSTAT and encompassed 16 provinces for the years 2003-2008. The model prepared included 11 independent variables on labor force, social mobility, living standard and R&D policy. The authors would have gladly considered more than 11 explanatory variable, but the inaccessibility of such data made it impossible. In the next step, using GRETL software, equations of regression were defined. On this basis it was concluded that the most important factors contributing to efficiency growth of SMEs are the amount of spending on R&D and the level of wages.

    Although there are already some qualification offers available for enterprises to support resource efficiency innovations, the high potentials that can be identified especially for small and medium sized enterprises (SMEs) have not been activated until now. As successful change lies in the hands of humans, the main aim of vocational education has to be the promotion of organisational and cultural changes in the enterprises. As there is already a small but increasing number of enterprises that perform very well in resource efficiency innovations one question arises: What are typical characteristics of those enterprises? Leaning on a good-practice approach, the project "ResourceCulture" is going to prove or falsify the hypothesis that enterprises being successful with resource efficiency innovations have a specific culture of trust, which substantially contributes to innovation processes, or even initially enables them. Detailed empirical field research will light up which correlations between resource efficiency, innovation and cultures of trust can be found and will offer important aspects for the improvement of management instruments and qualification concepts for workplace training. The project seizes qualification needs that were likewise mentioned by enterprises and consultants, regarding the implementation of resource efficiency. This article - based on first empirical field research results - derives preliminary indications for the design of the qualification module for the target groups resource efficiency consultants and managers. On this basis and in order to implement "ResourceCulture" conceptual and methodological starting points for workplace training are outlined. Copyright © 2013 Elsevier B.V. All rights reserved.

    1982-09-01

    The thermal-economic feasibility was studied of a medium-size central cogenerated energy facility designed to serve five varied industries. Generation options included one dual-fuel diesel and one gas turbine, both with waste heat boilers, and five fired boilers. Fuels included natural gas, and for the fired-boiler cases, also low-sulphur coal and municipal refuse. The fired-boiler cogeneration systems employed back-pressure steam turbines. For coal and refuse, the option of steam only without cogeneration was also assessed. The refuse-fired cases utilized modular incinerators. The options provided for a wide range of steam and electrical capacities. Deficient steam was assumed generated independently in existing equipment. Excess electrical power over that which could be displaced was assumed sold to Commonwealth Edison Company under PURPA (Public Utility Regulator Policies Act). The facility was assumed operated by a mutually owned corporation formed by the cogenerated power users. The economic analysis was predicted on currently applicable energy-investment tax credits and accelerated depreciation for a January 1985 startup date. Based on 100% equity financing, the results indicated that the best alternative was the modular-incinerator cogeneration system.

    Computational electronic structure calculations are routinely undertaken to predict thermodynamic properties of the various species. However, the application of highly accurate wave function theory methods, such as the “gold standard” coupled cluster approach including single, double and partly triple excitations in perturbative fashion, CCSD(T), to large molecules is limited due to high computational cost. In this work, the promising domain based local pair natural orbital coupled cluster approach, DLPNO-CCSD(T), has been tested to reproduce 113 accurate formation enthalpies of medium-size molecules (few dozens heavy atoms) important for bio- and combustion chemistry via the reaction based Feller-Peterson-Dixon approach. As for comparison, 8 density functional theory (B3LYP, B3LYP-D3, PBE0, PBE0-D3, M06, M06-2X, ωB97X-D3, and ωB97M-V) and MP2-based (B2PLYP-D3, PWPB95-D3, B2T-PLYP, B2T-PLYP-D, B2GP-PLYP, DSD-PBEP86-D3, SCS-MP2, and OO-SCS-MP2) methods have been tested. The worst performance has been obtained for the standard hybrid DFT functionals, PBE0 (Mean unsigned error (MUE)/ Mean Signed Error (MSE)=9.1/6.0 kcal/mol) and B3LYP (MUE/MSE=13.5/-13.3 kcal/mol). An influence of an empirical dispersion correction term on these functionals performance is not homogenous: B3LYP performance is improved (B3LYP-D3 (MUE/MSE=6.0/0.8 kcal/mol)) meanwhile PBE0 performance is worse (PBE0-D3 (MUE/MSE=14.1/13.6 kcal/mol)). The Minnesota functionals, M06 (MUE/MSE=3.8/-2.0 kcal/mol) and M06-2X (MUE/MSE=3.5/3.0 kcal/mol), and recently developed ωB97X-D3 (MUE/MSE=3.2/0.2 kcal/mol) and ωB97M-V (MUE/MSE=2.2/1.3 kcal/mol) methods provided significantly better formation enthalpies. Enthalpies of similar quality can also be obtained from some double hybrid methods (B2PLYP-D3 (MUE/MSE=4.7/2.0 kcal/mol), PWPB95-D3 (MUE/MSE=4.3/3.2 kcal/mol), B2T-PLYP (MUE/MSE=4.1/-3.0 kcal/mol) and B2T-PLYP-D (MUE/MSE=3.3/1.7 kcal/mol)). The two spin component scaled (SCS) MP2 methods resulted in

    Full Text Available Urbanization transforms undeveloped landscapes into built environments, causing changes in communities and ecological processes. Flying arthropods play important roles in these processes as pollinators, decomposers, and predators, and can be important in structuring food webs. The goal of this study was to identify associations between urbanization and the composition of communities of flying (and floating arthropods within gardens and parks in a medium-sized mesic city. We predicted that flying arthropod abundance and diversity would respond strongly to percent impervious surface and distance to city center, measurements of urbanization. Flying arthropods were sampled from 30 gardens and parks along an urbanization gradient in Toledo, Ohio, during July and August 2016, using elevated pan traps. A variety of potential predictor variables were also recorded at each site. We collected a total of 2,369 individuals representing nine orders. We found that flying arthropod community composition was associated with percent impervious surface and canopy cover. Overall flying arthropod abundance was negatively associated with percent impervious surface and positively associated with distance to city center. Hymenoptera (bees, wasps, ants, Lepidoptera (moths, butterflies, and Araneae (spiders were positively associated with distance to city center. Hemiptera (true bugs, Diptera (flies, and Araneae were negatively associated with percent impervious surface. Both distance to city center and percent impervious surface are metrics of urbanization, and this study shows how these factors influence flying arthropod communities in urban gardens and city parks, including significant reductions in taxa that contain pollinators and predators important to urban agriculture and forestry.

    Highlights: • Uncertainty analysis of reliability of Shutdown System is carried out. • Monte Carlo method of sampling is used. • The effect of various reliability improvement measures of SDS are accounted. - Abstract: In this paper, results are presented on the uncertainty evaluation of the reliability of Shutdown System (SDS) of a Medium Size Fast Breeder Reactor (MSFBR). The reliability analysis results are of Kumar et al. (2005). The failure rate of the components of SDS are taken from International literature and it is assumed that these follow log-normal distribution. Fault tree method is employed to propagate the uncertainty in failure rate from components level to shutdown system level. The beta factor model is used to account different extent of diversity. The Monte Carlo sampling technique is used for the analysis. The results of uncertainty analysis are presented in terms of the probability density function, cumulative distribution function, mean, variance, percentile values, confidence intervals, etc. It is observed that the spread in the probability distribution of SDS failure rate is less than SDS components failure rate and ninety percent values of the failure rate of SDS falls below the target value. As generic values of failure rates are used, sensitivity analysis is performed with respect to failure rate of control and safety rods and beta factor. It is discovered that a large increase in failure rate of SDS rods is not carried to SDS system failure proportionately. The failure rate of SDS is very sensitive to the beta factor of common cause failure between the two systems of SDS. The results of the study provide insight in the propagation of uncertainty in the failure rate of SDS components to failure rate of shutdown system.

    Full Text Available The main purpose of the present paper is to identify the framework and the necessary conditions for the small and medium sized enterprises (SMEs to be able to adopt the strategic marketing planning. Also, the paper aims to underline the importance of the strategic marketing planning and the manner in which the SMEs can adopt, implement and operationalize the strategic marketing planning instruments, whose correct understanding and usage ensure the capacity to generate competitive advantage, the key element both from the perspective of the fierce competition and the perspective of the future development of the SMEs. Within SMEs the implementation of marketing becomes an evident requirment, mostly due to the relationship that these have with the market, thus, leading towards market orientation of the activities, a new approach developed by the marketing vision on managing the activities from these types of organizations. Regarded upon, from the marketing perspective, the activities from the SMEs, especially the marketing activities, cannot take place randomly. Resource allocation, a characteristic of these types of organizations, and the objectives with regards to superior customer needs satisfaction and economic efficiency maximization, claim thorough plannification and deployment of the activities in a sequence that represents the implementation of a strategy previously assumed. Within this framework, the strategic marketing planning appears as a complex process employing all scientific instruments that comprise segmentation, positioning and marketing mix. Utilizing the strategic marketing planning within SMEs depends to further extend on marketing integration; process directly related with a series of factors such as the nature of the market, development stage, product type, management quality and the influences of the marketing department of the SME. The implications onto the marketing activities from SMEs are reflected upon each strategic

    Full Text Available Orientation: Customer relationship management (CRM is important to organisations striving for competitive advantage through building relationships with their customers.Research purpose: This study identified the factors preceding CRM and assessed selected South African small- and medium-sized tourism enterprises’ (SMTEs readiness for CRM.Motivation: CRM is likely to enhance SMTEs’ competitiveness. However, successful adoption and implementation of CRM is unlikely unless the organisation is ready for it.Research design, approach and method: A quantitative research approach and survey questionnaire yielded primary data from 332 respondent organisations selected by systematic sampling. Exploratory factor analysis was used to identify the latent factors preceding CRM readiness. Organisational CRM readiness was assessed based on CRM maturity in terms of data collection, use and sharing throughout the organisation.Main findings: Respondent-organisations performed well on the four factors preceding CRM readiness − business strategy, customer strategy, touch points and competencies, skills and technology and also on data collections and use, but not on data sharing.Practical/Managerial implications: CRM practice is believed to assist organisations in tailoring products and services to customers’ needs, providing customer satisfaction, enhancing customer retention and ultimately improving the organisation’s competitiveness and profitability. CRM might fail if SMTEs do not have CRM-enabling conditions in place and a CRM readiness audit should therefore be performed.Contribution: The study contributes to a largely under-researched area concerning CRM in SMTEs by providing an improved understanding of the factors that will enable SMTEs to engage in CRM activities.

    Full Text Available Background: Motorcycle vehicles are frequent in China, especially in the small and medium sized cities. Road traffic collisions involving motorcycles often result in severe injuries. We aimed to identify risk factors for severe injuries in inpatients sustaining motorcycle collisions. Methods: Patients with road traffic injuries involving motorcycles who presented to the neurosurgery and orthopedic departments of three major comprehensive hospitals in Shantou city were reviewed from October 2012 to June 2013. Data from 349 patients was investigated. Crash and injury characteristics were documented by interviewing patients, their family members, and their doctors. Binary logistic regression was used to determine risk factors for severe injuries. Results: There were 253 males (72.49% and 96 females (27.51%, with a male to female ratio of 2.64:1. The mean age was 38.21 ± 17.32 years. One-hundred and fifty patients were in the severe injury group with a mean injury severity score (ISS of 15.34 ± 9.13. The simple and multiple logistic model showed that males, lack of safeguards, morning and night hours, non-urban areas, collision of a motorcycle with a cycle, ambulance transportation to hospital, admission to a neurosurgery department, lack of traffic control, unobstructed traffic, and poor visibility were all the risk factors. Conclusions: This research highlights some problems: less helmet wearing in motorcyclists and cyclists, rural injuries being more serious than urban ones, and head injuries being the main diagnosis in severe injuries. The result of this research is predictable. If the safety equipment is required to be used, such as helmets, and the traffic environment is improved, such as traffic flow, medical resources to injuries and deaths is seasonable, then traffic safety will be improved and accidents will be reduced.

    Full Text Available The nucleus accumbens (NAc is a critical brain region involved in many reward-related behaviors. The NAc comprises major compartments the core and the shell, which encompass several subterritories. GABAergic medium-sized spiny neurons (MSNs constitute the output neurons of the NAc core and shell. While the functional organization of the NAc core outputs resembles the one described for the dorsal striatum, a simple classification of the NAc shell neurons has been difficult to define due to the complexity of the compartmental segregation of cells. We used a variety of BAC transgenic mice expressing enhanced green fluorescence (EGFP or the Cre-recombinase (Cre under the control of the promoter of dopamine D1, D2, and D3 receptors and of adenosine A2a receptor to dissect the microanatomy of the NAc. Moreover, using various immunological markers we characterized in detail the distribution of MSNs in the mouse NAc. In addition, cell-type specific ERK phosphorylation in the NAc subterritories was analyzed following acute administration of SKF81297 (a D1R-like agonist, quinpirole (a D2R-like agonist, apomorphine (a non-selective DA receptor agonist, raclopride (a D2R-like antagonist, and psychostimulant drugs, including cocaine and d-amphetamine. Each drug generated a unique topography and cell-type specific activation of ERK in the NAc. Our results show the existence of marked differences in the receptor expression pattern and functional activation of MSNs within the shell subterritories. This study emphasizes the anatomical and functional heterogeneity of the NAc, which will have to be considered in its further study.

    Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat and particle loads on the wall is a major challenge. The new European medium size tokamak task force (EU-MST) coordinates research on ASDEX Upgrade (AUG), MAST and TCV. This multi-machine approach within EU-MST, covering a wide parameter range, is instrumental to progress in the field, as ITER and DEMO core/pedestal and SOL parameters are not achievable simultaneously in present day devices. A two prong approach is adopted. On the one hand, scenarios with tolerable transient heat and particle loads, including active edge localised mode (ELM) control are developed. On the other hand, divertor solutions including advanced magnetic configurations are studied. Considerable progress has been made on both approaches, in particular in the fields of: ELM control with resonant magnetic perturbations (RMP), small ELM regimes, detachment onset and control, as well as filamentary scrape-off-layer transport. For example full ELM suppression has now been achieved on AUG at low collisionality with n  =  2 RMP maintaining good confinement {{H}\\text{H≤ft(98,\\text{y}2\\right)}}≈ 0.95 . Advances have been made with respect to detachment onset and control. Studies in advanced divertor configurations (Snowflake, Super-X and X-point target divertor) shed new light on SOL physics. Cross field filamentary transport has been characterised in a wide parameter regime on AUG, MAST and TCV progressing the theoretical and experimental understanding crucial for predicting first wall loads in ITER and DEMO. Conditions in the SOL also play a crucial role for ELM stability and access to small ELM regimes. In the future we will refer to the author list of the paper as the EUROfusion MST1 Team.

    This study, through a random national survey in the U.S., explored how corporate financial decision-makers perceive important workplace safety issues as a function of the size of the company for which they worked (medium- vs. large-size companies). Telephone surveys were conducted with 404 U.S. corporate financial decision-makers: 203 from medium-size companies and 201 from large companies. Results showed that the patterns of responding for participants from medium- and large-size companies were somewhat similar. The top-rated safety priorities in resource allocation reported by participants from both groups were overexertion, repetitive motion, and bodily reaction. They believed that there were direct and indirect costs associated with workplace injuries and for every dollar spent improving workplace safety, more than four dollars would be returned. They perceived the top benefits of an effective safety program to be predominately financial in nature - increased productivity and reduced costs - and the safety modification participants mentioned most often was to have more/better safety-focused training. However, more participants from large- than medium-size companies reported that "falling on the same level" was the major cause of workers' compensation loss, which is in line with industry loss data. Participants from large companies were more likely to see their safety programs as better than those of other companies in their industries, and those of medium-size companies were more likely to mention that there were no improvements needed for their companies.

  13. NEW APPROACHES TO CUSTOMER BASE SEGMENTATION FOR SMALL AND MEDIUM-SIZED ENTERPRISES

    Directory of Open Access Journals (Sweden)

    Meleancă Raluca-Cristina

    2012-12-01

    Full Text Available The primary purpose of this paper is to explore current praxis and theory related to customer segmentation and to offer an approach which is best suited for small and medium sized enterprises. The proposed solution is the result of an exploratory research aiming to recognize the main variables which influence the practice of segmenting the customer base and to study the most applied alternatives available for all types of enterprises. The research has been performed by studying a large set of secondary data, scientific literature and case studies regarding smaller companies from the European Union. The result of the research consists in an original approach to customer base segmentation, which combines aspects belonging to different well spread practices and applies them to the specific needs of a small or medium company, which typically has limited marketing resources in general and targeted marketing resources in particular. The significance of the proposed customer base segmentation approach lies in the fact that, even though smaller enterprises are in most economies the greatest in number compared to large companies, most of the literature on targeting practices has focused primarily on big companies dealing with a very large clientele, while the case of the smaller companies has been to some extent unfairly neglected. Targeted marketing is becoming more and more important for all types of companies nowadays, as a result of technology advances which make targeted communication easier and less expensive than in the past and also due to the fact that broad-based media have decreased their impact over the years. For a very large proportion of smaller companies, directing their marketing budgets towards targeted campaigns is a clever initiative, as broad based approaches are in many cases less effective and much more expensive. Targeted marketing stratagems are generally related to high tech domains such as artificial intelligence, data mining

    2010-01-01

    Full Text Available At the time of increasing globalization and homogenization of the global markets, the development of information infrastructure technology and world market becomes accessible not only to large multinational companies but also for small and medium-sized enterprises (SMEs. This has resulted in increasing competition in the domestic market which domestic firms have to face. Therefore the pro­cess of internationalization of business is a step that allows businesses performing their activities in the domestic market to enter foreign markets and to exploit the opportunities and potential which these markets offer. The paper is focused on the draft of the method for quantification of the factors, which determine the success of the SMEs in foreign markets. In the proposed method the multidimensional assessment of indicators of success of SMEs in foreign markets are used, ie. not only the proportion of sales from exports is observed, but also the profitability of international activities in an absolute and in a relative rate. Other indicators of success are the satisfaction of the company management with international activities and the success of achieving defined targets for business activities in foreign markets. Evaluation is made up of both the objective and the subjective indicators of success. Among the objective indicators of success is included the intensity of international activities of SMEs, which is detected as the sum of revenues generated from international activities in relation to total sales company, the profitability of international activities, (ie. whether the foreign activities are profitable or not, and the relative profitability of international activities, where it is ascertained whether the foreign activities generate higher profit than the activities at the domestic market. The next subjective indicator of success is the success of objectives - it was found how many objectives related to operations in foreign markets has been

    An account is given of the karyotypes of 29 species of medium sized Dytiscidae (Coleoptera). Of the 20 species of Agabus Leach, 1817, 18 have karyotypes comprising 21 pairs of autosomes and sex chromosomes which are either X0(♂) or XX (♀). These species are Agabus serricornis (Paykull, 1799), Agabus labiatus (Brahm, 1791), Agabus congener (Thunberg, 1794), Agabus lapponicus (Thomson, 1867), Agabus thomsoni (J. Sahlberg, 1871), Agabus confinis (Gyllenhal, 1808), Agabus sturmii (Gyllenhal, 1808), Agabus bipustulatus (Linnaeus, 1767), Agabus nevadensis Håkan Lindberg, 1939, Agabus wollastoni Sharp, 1882, Agabus melanarius Aubé, 1837, Agabus biguttatus (Olivier, 1795), Agabus binotatus Aubé, 1837, Agabus affinis (Paykull, 1798), Agabus unguicularis (Thomson, 1867), Agabus ramblae Millan & Ribera, 2001, Agabus conspersus (Marsham, 1802) and Agabus nebulosus (Forster, 1771). However two species, Agabus infuscatus Aubé, 1838 and Agabus adpressus Aubé, 1837, have developed a neo-XY system, with karyotypes comprising 21 pairs of autosomes and XY sex chromosomes (♂). No chromosomal differences have been detected between typical Agabus bipustulatus and Agabus bipustulatus var. solieri Aubé, 1837, nor have any been found between the three species of the Agabus bipustulatus complex (Agabus bipustulatus, Agabus nevadensis and Agabus wollastoni). The four species of Colymbetes Clairville, 1806, Colymbetes fuscus (Linnaeus, 1758), Colymbetes paykulli Erichson, 1837, Colymbetes piceus Klug, 1834 and Colymbetes striatus (Linnaeus, 1758) have karyotypes comprising 20 pairs of autosomes and sex chromosomes which are X0 (♂), XX (♀). Two of the species of Rhantus Dejean, 1833, Rhantus exsoletus (Forster, 1771) and Rhantus suturellus (Harris, 1828) have karyotypes comprising 20 pairs of autosomes and X0/XX sex chromosomes, but the other three species, Rhantus grapii (Gyllenhal, 1808), Rhantus frontalis (Marsham, 1802) and Rhantus suturalis (Macleay, 1825) have 22 pairs of

    Small- and medium-sized (<100,000 sf) commercial buildings (SMBs) represent over 95% of the U.S. commercial building stock and consume over 60% of total site energy consumption. Many of these buildings use rudimentary controls that are mostly manual, with limited scheduling capability, no monitoring or failure management. Therefore, many of these buildings are operated inefficiently and consume excess energy. SMBs typically utilize packaged rooftop units (RTUs) that are controlled by an individual thermostat. There is increased urgency to improve the operating efficiency of existing commercial building stock in the U.S. for many reasons, chief among them is to mitigate the climate change impacts. Studies have shown that managing set points and schedules of the RTUs will result in up to 20% energy and cost savings. Another problem associated with RTUs is short-cycling, where an RTU goes through ON and OFF cycles too frequently. Excessive cycling can lead to excessive wear and lead to premature failure of the compressor or its components. The short cycling can result in a significantly decreased average efficiency (up to 10%), even if there are no physical failures in the equipment. Also, SMBs use a time-of-day scheduling is to start the RTUs before the building will be occupied and shut it off when unoccupied. Ensuring correct use of the zone set points and eliminating frequent cycling of RTUs thereby leading to persistent building operations can significantly increase the operational efficiency of the SMBs. A growing trend is to use low-cost control infrastructure that can enable scalable and cost-effective intelligent building operations. The work reported in this report describes three algorithms for detecting the zone set point temperature, RTU cycling rate and occupancy schedule detection that can be deployed on the low-cost infrastructure. These algorithms only require the zone temperature data for detection. The algorithms have been tested and validated using

    On 15 December 2005, the European Medicines Agency (EMEA) launched an "SME Office" to provide financial and administrative assistance to micro-, small- and medium-sized enterprises (SMEs), with the aim of promoting innovation and the development of new human and veterinary medicinal products by SMEs. According to current EU definition of an SME, companies with fewer than 250 employees, and an annual turnover of not more than 50 million euro or an annual balance sheet total of not more than 43 million euro, are eligible for assistance from the SME Office. Incentives available from the EMEA for SMEs, include: Administrative and procedural assistance from SME Office within the Agency; Fee reductions (90%) for scientific advice and inspections; Fee exemptions for certain administrative services (excluding parallel distribution); Deferral of the fee payable for an application for marketing authorisation or related inspection until after the grant of the marketing authorisation; Conditional fee exemption where scientific advice followed and marketing application is unsuccessful; Assistance with translations of the product information documents. At the end of May 2009, more than 380 companies from 21 countries across the European Economic Area (EEA) had SME status assigned by the EMEA. The large majority of companies are developing medicinal products for human use, 16 are veterinary companies, 15 companies are developing products for both human and veterinary use and 38 are regulatory consultants. Since the SME initiative started the Agency has processed more than 130 requests for scientific advice with fee reductions totalling of 6.9 million euro. Regulatory assistance has been provided to more than 170 companies and 12 companies have benefited from the SME translation service. Stakeholders have acknowledged the significant role the SME Office now plays as a service provider. In the period between January 2006 and June 2009, 34 applications for marketing authorization

    The purpose of this report is to exemplify and clarify the need for ventilation in medium-sized and large boiler houses. We will furthermore present some recommendations, guidelines and advice for the design and construction of a boiler house ventilation system to the plant owners and suppliers of equipment. Boiler house ventilation can be performed in different ways using mechanical or natural ventilation. The solution to be chosen depends on the following factors: Working environment requirements and a necessity to control temperature and pressure in the boiler house; The design of the boiler plant and house; The need for combustion air; The investment expenditure as well as operation and maintenance costs. Mechanical ventilation should be chosen if the aim is a controllable 'climate'. The mechanical ventilation can be either centrally situated or distributed with many aggregates in the boiler house. Centrally situated ventilation equipment will give a higher accessibility and lower maintenance costs than a distributed ventilation system. If the boiler house is designed with natural ventilation the air and flue gas fans will be the only ones installed. In this case temperature and pressure inside the boiler house will be difficult to control. The design factor for the ventilation plant in a boiler house is in most cases the demand to cool the air inside the boiler house to approximately 45 deg C. This is the highest temperature allowed by the Occupational Safety and Health Act in a work environment where the boiler operator is working alone. The air flow which is required for the combustion is normally less than the air flow needed to cool the air in the boiler house. The supply air which is cooling the air inside the boiler house should be supplied on several different levels to attain an efficient cooling. If the combustion air is taken from the heated indoor air the boiler house will work as a heat reclaimer. The difference between outdoor and indoor

    In archaeology, it is not always possible to identify bone fragments. A novel approach was chosen to assess the potential of histology as an identification tool. Instead of studying a few bones of different categories from many species, this study concentrated on the diaphyses of long bones in four species of comparable size which are relevant to archaeology; young humans, pigs, sheep and goats, to broaden the insight into variations in diaphyseal bone structure within and between these species. A general difference in the primary bone structure was found between children older than one year and the three medium-sized mammals, namely lamellar vs. fibro-lamellar primary bone. Although, the diaphyseal bone structure of children below the age of one year also showed (developing) fibro-lamellar bone, its composition was distinctive from the medium-sized mammals. A difference in the secondary bone structure was also observed. Connecting (Volkmann's) canals, giving the secondary bone a reticular aspect, were seen in the medium-sized mammals but not in the young human long bones. To confirm the validity and applicability of these observed histological differences, a blind test was conducted on 14 diaphyseal fragments of identified long bones from archaeological sites. The results were very promising. All the bone fragments were correctly attributed using the difference in primary bone structure, even when the bone was severely degraded.

    The paper deals with the study of atmospheric particulate matter in medium and small settlements of Primorsky Region: Lesozavodsk town (Lesozavodsky urban district); settlements Gornye Kluchi and Ussurka (Kirovsky district); LDK settlement (Dalnerechensky urban district); villages Novopokrovka and Izmaylikha (Krasnoarmeysky district) by means of particle size analysis. It is shown that the atmosphere of each settlement contains microparticles sized under 10 μm (PM10) in significant proportions (over 20%). A conclusion is made that there is a need for continuous environmental and hygienic monitoring not only in big cities and heavily contaminated areas, but also areas that are considered environmentally safe.

    The article is based on the results of the project “Company integration management in small and medium-sized companies. Legal requirements and prerequisites for a successful implementation” (01 January 2009-31 August 2010). Since 2004 all employers have been legally bound to offer company integration management (BEM, Betriebliches Eingliederungsmanagement) for all employees who have been incapacitated for work for more than 6 weeks within a year (Section 84 SGB IX, Book 9 of the German Social Code). Objective of this law is to ensure ongoing employment. The aim of the study was to investigate the requirements companies, rehabilitation centres and services as well as social insurance institutions are faced with according to Section 84 SGB IX. Prerequisites for an effective implementation of BEM in small and medium-sized enterprises were analyzed. Protocol-based interviews with experts were adopted. A total of 38 interviews with experts were carried out. The experts interviewed were either willing to give information by interest (concernment) or were named by law as an initiator or co-operator in the process of integration. A substantial literature research was performed in advance of the interviews. The awareness level of BEM is still very low even 7 years after its introduction. Small and medium-sized enterprises do not have any significant experiential knowledge of long-term incapacity for work and, hence, about BEM. Due to a lack of workers representation in many small and medium companies, management does not receive initiatives or support in implementation of BEM from employees' side. Employers prefer a central contact point providing them with the information and help needed, the common service units, however, being widely unknown in this context. Cost comparisons suggest that a company integration management might be more cost-effective than dismissing employees who are incapacitated for some fields of work. These findings might even hold true for small

    Larger food portion sizes lead to increased energy intake levels and might contribute to the current obesity epidemic. Only a very limited number of studies are available on the actual development of food portion sizes during past decades. The present study aims to reveal trends in portion sizes of some high-energy-dense food products during recent decades in The Netherlands. The data were collected from manufacturers and from information found in professional journals, marketing and advertising materials, and on manufacturers' websites. A number of trends in food portion sizes were observed. Larger sizes have been added to the portion size portfolio. The portion sizes of a number of products have also increased since their introduction, although this did not apply to all the products included. Finally, multi-packs have been introduced and the number of products within a multi-pack has also increased. A trend towards larger portion sizes was observed, which is relevant to the public health debate regarding the prevention of overweight and obesity. It is recommended that developments in food portion sizes continue to be monitored over the coming years, and the effects of the newly introduced portion sizes on food intake be studied.

    Full Text Available The objective of this research is to determine the competitiveness level of the manufacturing small and medium-sized enterprises (SMEs of Baja California and to identify which areas within them affect this competitiveness. The methodology used is descriptive, correlational, and cross-sectional; the systemic competitiveness model is developed at the micro level, and a measurement instrument with 64 questions is used on 195 companies in the state; in addition, traditional multiple linear regressions are performed to test the hypotheses. One of the findings is that the SMEs in the state have a medium-low competitiveness level and do not show any relationship between the size of the companies and their competitiveness; however, the production-operations area prove to be more important for their competitiveness level. Although the measurement instrument that is used has no proportionality at the municipality and subsector level, it does allow us to approach the internal operation of the SMEs.

  6. Determinants of small and medium sized fast growing enterprises in central and eastern Europe: a panel data analysis

    Full Text Available The purpose of this paper is to explore the main determinants of growth in small and medium sized enterprises (SMEs in central and eastern Europe. The important role played by SMEs in the economic development of central and eastern European (CEE countries has attracted the recent attention of academics and policymakers but remains relatively unexplored. Empirical research has suggested that firm growth is determined not only by the traditional characteristics of size and age but also by other firm-specific factors such as indebtedness, internal financing, future growth opportunities, process and product innovation, and organisational changes. Although growth in manufacturing and service SMEs in transition economies is well explained by the traditional firm characteristics of size and age, there is no empirical evidence concerning what other specific factors may be associated with SME growth and performance in these countries. Using a panel dataset of 560 fast growing small and medium enterprises from six transition economies we find that firm size when measured by firm total assets can explain to a large extent the growth in SMEs in these countries. When size is proxied by a firm’s number of employees the observed effect is marginal. Firm specific characteristics such as leverage, current liquidity, future growth opportunities, internally generated funds, and factor productivity are found to be important factors in determining a firm’s growth and performance. Age and ownership do not seem to be able to explain firm growth. The results of our empirical study have also some policy implications: we argue that governments in transition economies need to pay an increased attention to small and medium sized enterprises and try to create a business environment that will be beneficial for SME development.

    2011-10-01

    Small businesses need to engage in continuity planning to assure delivery of goods and services and to sustain the economy during an influenza pandemic. This is especially true in New York City, where 98 per cent of businesses have fewer than 100 employees. It was an objective therefore, to determine pandemic influenza business continuity practices and strategies suitable for small and medium-sized NYC businesses. The study design used focus groups, and the participants were owners and managers of businesses with fewer than 500 employees in New York City. The main outcome measures looked for were the degree of pandemic preparedness, and the feasibility of currently proposed business continuity strategies. Most participants reported that their businesses had no pandemic influenza plan. Agreement with feasibility of specific business continuity strategies was influenced by the type of business represented, cost of the strategy, and business size. It was concluded that recommendations for pandemic-related business continuity plans for small and medium-sized businesses should be tailored to the type and size of business and should highlight the broad utility of the proposed strategies to address a range of business stressors.

    Full Text Available Studies related to community ecology of medium and large mammals represent a priority in developing strategies for conservation of their habitats. Due to the significant ecological importance of these species, a concern in relation to anthropogenic pressures arises since their populations are vulnerable to hunting and fragmentation. In this study, we aimed to analyze the diversity of medium and large mammals in a representative area of the Cerrado biome, located in the National Forest of Silvânia, central Brazil, providing insights for future studies on the biodiversity and conservation of Cerrado mammals. Sampling was carried out by linear transects, search for traces, footprint traps and camera traps. We recorded 23 species, among which three are listed in threat categories (e.g., Myrmecophaga tridactyla, Chrysocyon brachyurus and Leopardus tigrinus. We registered 160 records in the study area, where the most frequently recorded species were Didelphis albiventris (30 records and Cerdocyon thous (28 records. Our results indicated that a small protected area of Cerrado can include a large and important percentage of the diversity of mammals in this biome, providing information about richness, abundance, spatial distribution and insights for future studies on the biodiversity and conservation of these biological communities.

    The developed countries have been prepared the national innovation for sustainable development for a long time. The international advanced enterprises, such as multinational enterprises, are enhancing the active and strategic environmental management. However, in spite of such changes in the world, small and middle-sized enterprises do not show any substantial changes. It is true that most of enterprises do not recognize the need of environmental management. Although they have intention for environmental improvement, it is also true that they do not have any strength to maintain effective management. Moreover, with over 99% of small and middle-sized enterprises among entire enterprises in Korea, it is hardly possible to establish an effective regulation system. The purpose of this study is to make a policy plan to induce the development of environmental friendly small and middle-sized enterprises under the recognition of such problems. 138 refs., 4 figs., 195 tabs.

    The study objectives were (1) to conduct a systematic review of the performance of capture-recapture methods; (2) to use empirical data to estimate population size in a small-sized population (turkey breeder farms) and a medium-sized population (meat turkey farms) by applying two-source capture-recapture methods (the Lincoln-Petersen, the Chapman, and Chao's lower-bound estimators) and multi-source capture-recapture methods (the log-linear modeling and sample coverage approaches); and (3) to compare the performance of these methods in predicting the true population sizes (2007 data). Our set-up was unique in that we knew the population sizes for turkey breeder farms (99) and meat turkey farms (592) in Canada in 2007, which we applied as our true population sizes, and had surveillance data from the Canadian Notifiable Avian Influenza Surveillance System (2008-2012). We defined each calendar year of sampling as a data source. We confirmed that the two-source capture-recapture methods were sensitive to the violation of the local independence assumption. The log-linear modeling and sample coverage approaches yielded estimates that were closer to the true population sizes than were the estimates provided by the two-source methods for both populations. The performance of both multi-source capture-recapture methods depended on the number of data sources analyzed and the size of the population. Simulation studies are recommended to better understand the limits of each multi-source capture-recapture method. Crown Copyright © 2014. Published by Elsevier B.V. All rights reserved.

    This study analyzes the efficiency of small and medium-sized enterprises (SMEs) of a national technology innovation research and development (R&D) program. In particular, an empirical analysis is presented that aims to answer the following question: "Is there a difference in the efficiency between R&D collaboration types and between government R&D subsidy sizes?" Methodologically, the efficiency of a government-sponsored R&D project (i.e., GSP) is measured by Data Envelopment Analysis (DEA), and a nonparametric analysis of variance method, the Kruskal-Wallis (KW) test is adopted to see if the efficiency differences between R&D collaboration types and between government R&D subsidy sizes are statistically significant. This study's major findings are as follows. First, contrary to our hypothesis, when we controlled the influence of government R&D subsidy size, there was no statistically significant difference in the efficiency between R&D collaboration types. However, the R&D collaboration type, "SME-University-Laboratory" Joint-Venture was superior to the others, achieving the largest median and the smallest interquartile range of DEA efficiency scores. Second, the differences in the efficiency were statistically significant between government R&D subsidy sizes, and the phenomenon of diseconomies of scale was identified on the whole. As the government R&D subsidy size increases, the central measures of DEA efficiency scores were reduced, but the dispersion measures rather tended to get larger.

    For the decades, organizations have endeavored to look for external sources for opportunities to achieve efficient and responsive supply chain with their partners especially for small and medium manufacturers (SMM). In this scenario, supply chain collaboration (SCC) is an interaction between supply chain members with the purpose of utilizes the knowledge and resources of customers and suppliers, and integrates the flows of products and information in order to achieve a common goal and obtain mutual benefit. The essential SCC dimensions for SMMs comprised of information sharing, joint knowledge creation, joint decision making, goal congruence and incentive sharing. The successful implementation of SCC can give SMMs an edge over their competitors. This paper aims to introduce a review of SCC practices for SMM. Overall, the findings provide managerial insights for the SMM in SCC implementation owing to resource scarcity and the need to draw SCC in order to ensure a sustainable competitive advantage.

    Small and medium enterprises (SMEs) are a major source of dynamism, innovation and flexibility for emerging and developing countries, as well as for the economies of the most industrialised nations. However, the survival and growth of SMEs can be difficult in the current competitive business environment and global marketplace. It can be a real challenge to deliver the right product and service at the most opportune time and at the lowest possible cost to the right customer. The challenge stresses the importance of managing cross-boundary relationships between business partners. For gaining a competitive advantage, supply chain management (SCM) is an effective tool to SMEs. Therefore, this paper aims to review the tenet of SCM, its benefits and practices to SMEs.

    Full Text Available The use of self-compacting concrete (SCC has been on the rise in recent years. Research on this type of concrete has focused primarily on determining optimal dosage, while durability, particularly for medium strength SCC, has received much less attention. The present study explored the permeability of a number of medium strength (characteristic strength, 30 MPa self-compacting concretes, including SCCs made with common cement, in pursuit of a balance between performance and cost. Pressurised water and mercury intrusion porosimetry tests were conducted to determine concrete behaviour when exposed to aggressive agents. The findings showed that the capillary networks of these concretes are essentially impermeable to aggressive agents.

    El hormigón autocompactante ha experimentado un amplio desarrollo en los últimos años. Los estudios sobre este hormigón se han centrado en obtener dosificaciones óptimas, mientras los relativos a su durabilidad son escasos, especialmente en el caso de hormigones de resistencia moderada. Este trabajo se centra en el estudio de la permeabilidad de distintos hormigones autocompactantes de resistencia moderada (resistencia característica 30 MPa. El estudio incluye hormigones fabricados con cementos comunes, en los que se ha buscado un equilibrio entre prestaciones y precio. Con el fin de estudiar su comportamiento frente a la penetración de agentes agresivos, se han realizado los ensayos de permeabilidad al agua bajo presión y estudio de la porosimetría por intrusión de mercurio. Los resultados de los ensayos ponen de manifiesto el buen comportamiento de estos hormigones frente a la posible penetración de agentes agresivos por la red capilar.

    Full Text Available On a daily basis, enterprises of all sizes cope with the turbulence and volatility of market demands, cost variability, and severe pressure from globally distributed competitors. Managing uncertainty about future demand requirements and volumes in supply-chain networks has become a priority. One of the ways to deal with uncertainty is the utilization of simulation techniques and tools, which provide greater predictability of decision-making outcomes. For example, simulation has been widely applied in decision-making processes related to global logistics and production networks at the strategic, tactical, and operational levels, where it is used to predict the impact of decisions before their implementation in complex and uncertain environments. Large enterprises are inclined to use simulation tools whereas small and medium-sized enterprises seem to underestimate its advantages. The objective of this article is to emphasize the relevance of simulation for the design and management of supply-chain networks from the perspective of small and medium-sized firms.

    Full Text Available BACKGROUND: Recent work on the Jurassic-Cretaceous transition of the Iberian Range (Spain has opened a new window onto the interpretation of the trackmakers of some medium-sized tridactyl tracks. The ichnotaxon Therangospodus oncalensis has been described in the Huérteles Formation (Berriasian and is one of the classical tracks from the area assigned to medium-sized theropods. METHODOLOGY/PRINCIPAL FINDINGS: A review of the type locality of Therangospodus oncalensis (Fuentesalvo tracksite and other tracksites from the Huérteles Formation (Berriasian has yielded new information on the morphology, gait and trackmaker identity of the aforementioned ichnospecies. The new data suggest that the trackmaker is an ornithopod rather than a theropod on the basis of the length/width ratio, the anterior triangle length-width ratio, the short steps, the round to quadrangular heel pad impression and the probable manus impressions. CONCLUSIONS/SIGNIFICANCE: T. oncalensis shows similarities with various tracks from the Berriasian of Europe assigned to Iguanodontipus. The ichnotaxonomical status of this ichnospecies is here considered as Iguanodontipus? oncalensis due to the current state of knowledge of the ichnotaxonomy of medium-sized ornithopod tracks. This reassessment of I? oncalensis also has two significant implications for the palaeoecology of the faunas during the deposition of the Huérteles Formation: 1- the high number and percentage of theropod tracks would be lower than previous papers have suggested. 2- the gregarious behaviour described in the type locality (Fuentesalvo would be among ornithopods instead of theropods.

    The Cherenkov Telescope Array (CTA) is an international project for a next-generation ground-based gamma-ray observatory. CTA, conceived as an array of tens of imaging atmospheric Cherenkov telescopes, comprising small, medium and large-size telescopes, is aiming to improve on the sensitivity of current-generation experiments by an order of magnitude and provide energy coverage from 20 GeV to more than 300 TeV. The Schwarzschild-Couder design is a candidate 9-m diameter medium-sized telescope featuring a novel aplanatic two-mirror optical design capable of a wide field of view with significantly improved imaging resolution as compared to the traditional Davies-Cotton optical design. Achieving this imaging resolution imposes strict mirror alignment requirements that necessitate a sophisticated alignment system. This system uses a collection of position sensors between panels to determine the relative position of adjacent panels; each panel is mounted on a Stewart platform to allow motion control with six degrees of freedom, facilitating the alignment of the optical surface for the segmented primary and secondary mirrors. Alignments of the primary and secondary mirrors and the camera focal plane with respect to each other are performed utilizing a set of CCD cameras which image LEDs placed on the mirror panels to measure relative translation, and custom-built auto-collimators to measure relative tilt between the primary and secondary mirrors along the optical axis of the telescope. In this contribution we present the status of the development of the SC optical alignment system, soon to be materialized in a full-scale prototype SC medium-size telescope (pSCT) at the Fred Lawrence Whipple Observatory in southern Arizona.

    Full Text Available The asset structure of companies should matter for financing decisions. Small and medium-sized companies in Croatia may use tangible assets as collateral, either providing more access to creditors or as a guarantee in case of bankruptcy. The aim of this paper is to investigate the relationship between tangible assets and the capital structure of Croatian small and medium-sized enterprises. Most previous studies have shown various relationships between tangible assets and leverage. This study has been conducted on a sample of 500 Croatian SMEs for the period between 2005 and 2010. The data used for the empirical analysis were taken from companies’ annual reports. The Pearson Correlation Coefficient is applied in order to examine the relationship between tangible assets and leverage measures. The results of this research indicate that tangible assets are differently correlated with short-term and long-term leverage. The relationship between tangible assets and short-term leverage is negative and statistically significant in all observed years. The relationship between tangible assets and long-term leverage is positive in all observed years and statistically significant. The results show that small and medium-sized companies use their collateral to attract long-term debt, which means that small and medium-sized companies use lower costs and the interest rate of long-term debt in relation to short-term debt. These findings correspond with the maturity matching principle, according to which long-term assets are financed with long-term financing and short-term assets are financed with short-term funds. These results suggest that tangible assets have a positive impact on the long-term debt of Croatian SMEs because tangible assets constitute a positive signal to the financial institutions, which can request the selling of these assets in case of bankruptcy. These findings are consistent with the trade-off theory which predicts a positive relation

    A set of molecular dynamics simulations were performed to investigate the effect of cooling rate and system size on the medium-range structure of melt-derived multicomponent silicate glasses, represented by the quaternary 45S5 Bioglass composition. Given the significant impact of the glass degradation on applications of these materials in biomedicine and nuclear waste disposal, bulk structural features which directly affect the glass dissolution process are of particular interest. Connectivity of the silicate matrix, ion clustering and nanosegregation, distribution of ring and chain structural patterns represent critical features in this context, which can be directly extracted from the models. A key issue is represented by the effect of the computational approach on the corresponding glass models, especially in light of recent indications questioning the suitability of conventional MD approaches (that is, involving melt-and-quench of systems containing ∼10{sup 3} atoms at cooling rates of 5-10 K/ps) when applied to model these glasses. The analysis presented here compares MD models obtained with conventional and nonconventional cooling rates and system sizes, highlighting the trend and range of convergence of specific structural features in the medium range. The present results show that time-consuming computational approaches involving much lower cooling rates and/or significantly larger system sizes are in most cases not necessary in order to obtain a reliable description of the medium-range structure of multicomponent glasses. We identify the convergence range for specific properties and use them to discuss models of several glass compositions for which a possible influence of cooling-rate or size effects had been previously hypothesized. The trends highlighted here represent an important reference to obtain reliable models of multicomponent glasses and extract converged medium-range structural features which affect the glass degradation and thus their

    2017-01-01

    The development of digital technologies for manufacturing has been challenged by the difficulty of navigating the breadth of new technologies available to industry. This difficulty is compounded by technologies developed without a good understanding of the capabilities and limitations of the manufacturing environment, especially within small-to-medium enterprises (SMEs). This paper describes industrial case studies conducted to identify the needs, priorities, and constraints of manufacturing SMEs in the areas of performance measurement, condition monitoring, diagnosis, and prognosis. These case studies focused on contract and original equipment manufacturers with less than 500 employees from several industrial sectors. Solution and equipment providers and National Institute of Standards and Technology (NIST) Hollings Manufacturing Extension Partnership (MEP) centers were also included. Each case study involved discussions with key shop-floor personnel as well as site visits with some participants. The case studies highlight SME's strong need for access to appropriate data to better understand and plan manufacturing operations. They also help define industrially-relevant use cases in several areas of manufacturing operations, including scheduling support, maintenance planning, resource budgeting, and workforce augmentation.

  20. Organizational Culture and Open Innovation Performance in Small and Medium-sized Enterprises (SMEs in Poland

    Mazur Jolanta

    2016-09-01

    Full Text Available This study investigates the links between organizational culture, the use of open innovation sources and the performance of SMEs. The main hypothesis of the study is that a special type of organizational culture (termed innovative culture, which fosters creativity, learning and inter-employee cooperation – will correspond with a greater scope of open innovation sources and higher levels of innovative, operational and financial performance. The study was based on a representative CATI survey of 473 SMEs operating in manufacturing and services industries in Poland. Our statistical analysis relied on building and testing structural equation model with the AMOS software. The findings confirmed a positive association between innovative culture and the scope of open sources of innovation. However, innovative culture had no direct effect on the percentage of sales from new and modified products, which is often used as a metric of innovativeness, but did show a positive influence on an index of operational performance and ROI. Such statistical patterns suggest that fostering innovative culture is beneficial to a company, though probably not through an increased number of product innovations, but rather via process, administrative and marketing innovations, as well as other gains in efficiency attained due to more streamlined employee cooperation and knowledge exchange. The study adds to the existing body of knowledge in management science by providing a better understanding of mechanisms underlying innovative culture’s impacts on open innovation practices and metrics of operational and financial performance in the context of small and medium enterprises.

    A modeling approach based on the maximum likelihood has been used to extract quantitative morphological and structural parameter estimates for over 15,000 faint galaxy images observed with the Hubble Space Telescope (HST) Wide Field Camera. Because convolved galaxy images are compared directly with the observations, we avoid the need for deconvolution, which is difficult and potentially unstable for faint images. Direct comparison of structural parameters measured from WFC and WFPC2 observations of the same objects in fields observed by both instruments show results that are consistent within the nominal errors derived in the procedure itself. The procedure successfully measures the parameters of faint galaxies, despite the potential difficulties related to the aberration in WF/PC and to the undersampling in WFPC2.' We illustrate the procedure as applied to process both WF/PC and WFPC2 data and present results from the HST Medium Deep Survey galaxy catalog which has now been made available through the HST archive. This work was supported by NASA/HST grants GO-2684-0*-94A from STScI, which is operated by AURA, Inc., under NASA contract NAS5-26555.

    Full Text Available We analysed yearly estimates of population size data during 2001-2012 for five carnivores species of conservation interest (Ursus arctos, Canis lupus, Lynx lynx, Felis silvestris and Canis aureus. Population size estimations were done by the game management authorities and integrated by the competent authorities on the Ministry of Environment and Climate Change. Trends in data were detected using non-parametric Mann-Kendall test. This test was chosen considering the short length of data series and its usefulness for non-normal distributed data. The trend was tested at three spatial scales: game management units (n=1565, biogeographical region (n=5 and national. Trends depicted for each game management unit were plotted using ArcGIS, resulting species trend distribution maps. For the studied period increasing population trends were observed for Ursus arctos, Canis lupus, Canis aureus and Lynx lynx, while for Felis silvestris there was no trend recorded. Such an analysis in especially useful for conservation proposes, game management and reporting obligations under article 17 of the EC Habitat Directive, using population trend as a proxy for population dynamics. We conclude that the status of the five carnivore species is favourable during the study period.

    Seed tracer particles must be large enough to scatter sufficient light while being sufficiently small to follow the flow. These requirements motivate a desire for control over the particle size. For gas measurements, it is common to use atomized oil droplets as tracer particles. A Laskin nozzle is a device for generating oil droplets in air by directing high-pressure air through small holes under an oil surface. The droplet diameter frequency distribution can be varied by altering the hole diameter, the number of holes, or the inlet pressure. We will present a systematic study of the effect of these three parameters on the resultant particle distribution as it leaves the Laskin nozzle. The study was repeated for cases where the particles moved through a typical jet facility before their size was measured. While the jet facility resulted in an elimination of larger particles, the average particle diameter could be varied by a factor of two at both the seeder exit and downstream of the jet facility.

    Meteorite impacts are a common occurrence throughout Earth's geologic history. Many of the surface expressions of large ancient impacts have been subsequently erased by weathering and erosion processes. The study of preserved meteorite impacts is necessary to better understand this natural hazard which has been increasingly linked to rapid climate change and mass extinctions. The 60 ka Odessa meteorite crater located in Ector Co. Texas, is unique because it is not only well-preserved, but also has been the subject of extensive geologic examination. Geologic mapping and numeric models indicate that the crater was caused by a relatively small oblique impactor. The crater rim is remarkably well exposed. Much of the ejecta blanket is present, although deeply eroded. There has been considerable site disturbance due to drilling, shaft excavation, trenching, construction of a museum, trails, and the oil/gas activity in surrounding fields. Two previous geophysical investigations have shown that our data clearly corresponds to large-scale thrust deformation. With this in mind we have performed 3D high resolution magnetic gradiometer surveys that will allow us to quantify and characterize the magnetic signature of small to medium impacts. We will tie this data set to a 3D photorealistic outcrop image provided by laser scanning with coarser-scale, below-ground geophysical information. Our geophysical imagery provides a useful constraint on numerical simulations of the impact and its immediate regional-scale environmental effects. This information can be used to identify impact sites whose surface expression has been erased by natural erosional processes, allowing for improved frequency estimates and improved geo-hazard assessment.

    Full Text Available In The European Union’s country members, small and medium-sized enterprises (SMEs play an essential role in economic life, having special features that make adaptation process to the contemporary economy easier. Small and medium sized enterprises (SMEs are the most dynamic and vital factor of progress in the contemporary society, main generator of economic performance and substance in any country, employment opportunity provider for most of population, major contributor to the national budget, and engine to improve the living standard of the population. SMEs represent 99% from all enterprises, drawing up the main human resources aglomeration. In the contemporary economic context, SMEs should act as learning entities, by developing the most important resources they own: the human resources. Human resource development (HRD has gained a permanent role within SMEs, agencies and nations, increasingly not only as an academic discipline, but as a central theme in development area. Being a combination of training and education, in a broad context of adequate human resource policies, HRD ensures the continual improvement and growth of both individual and organization.

    Ultrasound-guided percutaneous ethanol injection (US-guided PEI) is used in patients with recurring symptomatic thyroid cysts in whom simple drainage was not successful. It is an alternative non-surgical approach in patients refusing or at risk during surgery. US-guided PEI was performed in 33 patients, with a success rate of 100% and significantly decreased cyst volume after 1, 3 and 6 months after the last PEI compared with the initial volume. The mean number of PEI procedures was 1.5±0.7 with a mean 96% ethanol volume of 2.4±1.2 mL. In the entire group, the initial cyst volume was significantly reduced to the final volume at 6 months after PEI (10.82±5.03 mL vs. 0.78±0.84 mL; Pethanol was equal to 22.7±7.9% of the initial cyst volume. Our experiences confirm that small and medium-sized cysts may be successfully treated with relatively small amounts of ethanol. In case of medium-sized cysts, more PEI procedures were needed. Final reduction of complex cysts was achieved later. Apart from temporary localized pain, no serious complications were observed in most cases.

    To retrospectively investigate the safety and efficacy of hybrid proximal coiling of various medium-sized vessels (4 to 8 mm) using the Penumbra Occlusion Device (POD). From October 2014 to February 2016, 37 proximal embolizations were performed with PODs in 36 patients (mean age: 50.8, range: 10-86; 29 male, 7 female). Vessel occlusions were achieved under fluoroscopic guidance using a 2.7 French microcatheter. Among the 36 vessels targeted, 16 were splenic arteries, 11 renal arteries, 4 mesenteric arteries, 3 arteriovenous fistulae, 1 iliac artery, and 1 gonadal vein. Intermittent follow-up angiography was performed to assess the flow for final occlusion. Outcomes and complications were assessed by clinical and/or imaging follow-up. To produce proximal occlusion of the intended vessels, the POD was used alone in 19 embolizations (51.4 %). In 12 procedures (32.4 %), POD was used as a coil constrainer to secure the coil construct. In 6 procedures (16.2 %), additional embolic devices were used to achieve vessel occlusion after initial POD deployment. After a mean follow-up of 3.2 months, no POD migration was observed but two complications occurred (5.4 %): one post embolic syndrome and one extensive infarction with splenic abscess. The POD system allows safe and effective proximal embolization of medium-sized vessels in a variety of clinical settings.

    2016-06-01

    Full Text Available Modern scientific research in the field of risk management is mainly devoted to general questions of the market theory of risk management, including qualitative risk analysis, protection of the rights of property owners and the study of the problems of selection of the best strategies for profitable market investments. The development of risk management mechanisms for small- and medium-sized businesses in Lithuania compared to other European markets is happening too slowly. The situation is aggravated by unstable situation of the field itself, corrupted officials and the lack of advanced control strategies for internal and external risk management in organisations. All these factors confirm the need to develop new management tools in the field of risk management at such enterprises. The aim of this article is to develop the mechanism of risk management of small and medium-sized businesses and justify it scientifically. The methodology of the research is based on the principles of objectivity using methods of comparative, logical, mathematical statistics and system-structural analysis.

    Full Text Available Companies classified as small and medium-sized enterprises (SMEs account for a large proportion of Europe’s economic and professional activity. In practice, 99 % of business in the European Union are SMEs, and they provide two–thirds of all private sector jobs. So small firms are, in fact, the real ­giants of the European economy. Micro–business dominate employment in countries such as Italy 47 % and Poland 41 %, whilst the share of large enterprises in total employment in the United Kingdom is just 46 %.During the recent period of time there have been many researchers from the FBE MUAF in Brno, who focused on the analysis of the small and medium-sized enterprise, e.g. Nerudová (2006; Nerudová and Bohušová (2006; Kubíčková and Presová (2006; Zrůst and Pyšný (2008; Živělová and Zichová (2002.This paper is the part of the Research proposal MSM 6215648904 being solved at the FBE MUAF in Brno.

  12. An empirical study on the critical success factors of small to medium sized projects in a South African mining company

    Du Randt, Francois Jean

    2014-08-01

    Full Text Available Projects that fail, for whatever reason, can impact negatively on society, organisations, and other stakeholders. A number of researchers have identified various critical success factors (CSFs that can influence the outcome and success of a project. This research therefore aims to determine the CSFs that influence various success measures of small- to medium-sized projects at a South African mining company, Exxaro Resources’ Grootegeluk Coal Mine. Other objectives of this research include determining the extent of the impacts of these CSFs on the different success measures of a project. The investigation suggests that there are correlations among CSFs, and that certain factors impact the outcome of projects far more than others. This research finds that the single most important CSF for small- to medium-sized projects is the selection of a competent project manager. The competent project manager is characterised by a group of interrelated CSF factors: good leadership, commitment, and learning from past experiences. Based on the research results, other CSFs are discussed and explored in order for recommendations to be made on how this mining company, and possibly other organisations, can achieve greater project success.

    Large-scale kinetic simulations of toroidal plasmas based on first principles are called for in studies of transition from low to high confinement mode and internal transport barrier formation in the core plasma. Such processes are best observed and diagnosed in detached plasma conditions in mid-sized tokamaks, so gyrokinetic simulations for these conditions are warranted. A first principles test-particle based kinetic model ELMFIRE[1] has been developed and used in interpretation[1,2] of FT-2 and DIII-D experiments. In this work we summarize progress in Cyclone (DIII-D core) and ASDEX Upgrade pedestal region simulations, and show that in simulations the choice of adiabatic electrons results in quenching of turbulence (copyright 2010 WILEY-VCH Verlag GmbH and Co.

    In 2014, Marshall McCall mapped out our Local Sheet, the cosmic wall containing the Milk Way and Andromeda galaxies. We use the large new Bolshoi-Planck cosmological simulation to investigate how rare our type of Local Sheet is, with 2 nearby halos like those of Milky Way and Andromeda. The conclusion of our investigation is that the occurrence of a pair of galaxies the size of Milky Way and Andromeda near the center of a wall 8 mpc in diameter, with the pair of galaxies within 0.7 mpc/h of each other, is very rare : it makes up only 0.05% of all walls in the simulation.

  15. Use of recycling through medium size granular filters to treat small food processing industry effluents.

    Ménoret, C; Boutin, C; Liénard, A; Brissaud, F

    2002-01-01

    Currently there are no suitable wastewater treatment systems for effluents from small food processing industries (dairy, cheese, wine production). Such raw sewages are characterized by high organic matter concentrations (about 10 g COD L-1) and relatively low daily volumes (about 2 m3). An adaptation of attached-growth cultures on fine media processes, known to be easy and inexpensive to use, could fit both the technical and economical context of those industries. Coarser filter particle size distributions than those normally used allow a better aeration and reduce clogging risk. The transit time of the effluent through the porous filter materials is shortened and requires recycling to increase the contact time between the biomass and the substrate. A pilot plant was built to compare the efficiency of two kinds of filter materials, gravel (2-5 mm) and pozzolana (3-7 mm). Two measurement campaigns were undertaken on a full-scale unit dealing with cheese dairy effluents. Both pilot-scale and full-scale plants show high COD removal rates (> 95%). Pilot-scale experiments show that accumulation of organic matter leads to the clogging of the recycling filter. To prevent early clogging, a better definition of feeding cycles is needed.

    2017-09-01

    Full Text Available Objective: The study goal was the investigation of relationships between accelerated internationalisation descriptors and antecedent firm- and entrepreneur-related factors in Polish and Czech SMEs. Research Design & Methods: In order to compare Polish and Czech companies, the data collected in two independent studies were used. The study of 233 Polish companies was conducted with the use of CATI method in 2014; 108 Czech companies were surveyed in 2013/2014 with the use of CAWI method. In both samples half of the surveyed SME-exporters were conforming to the accelerated internationalisation criteria. Findings: In both samples the “global vision” elements and company internationalisation scale and speed were interrelated. In the Polish companies this relationship was moderated by company size. There was the lack of strong positive relationships between innovativeness and internationalisation speed and scale in both samples. Implications & Recommendations:The managerial mindset has a decisive role for accelerated internationalisation in both Czech and Polish SMEs. The innovativeness of offering is not indispensable for fast foreign expansion. Larger companies may expand abroad faster if they have internationally oriented managers. Contribution & Value Added:This work addresses a research gap concerning idiosyncrasies of internationalisation antecedents in Polish and Czech enterprises. As the results show, there is no common internationalisation pattern for Polish and Czech SMEs.

    2012-11-01

    Full Text Available SMMEs can make a critical and positive economic contribution to South Africa, and small- to medium-sized furniture manufacturers (SM/FMs have the potential to contribute to economic growth, job creation, and GDP. However, the furniture industry has not stayed abreast of technological advances. To survive in an environment of increasing competition and imports, competitive strategies must be devised. One such strategy is for technology adoption and implementation that can provide solutions for the furniture industry to improve speed, quality, variety, flexibility, and productivity, resulting in improved competitiveness. However, the adoption of technology means that its acquisition and application must be managed strategically, as the use of technology involves far more than simply taking it into account during the business-plan

    2014-07-01

    Full Text Available In this study family-related factors that can influence the succession process in small and medium-sized family businesses are empirically investigated.  The dependent variable in this study is measured by two underlying dimensions, namely satisfaction with the process and continued profitability of the business.  The empirical results indicate that the family-related factors that influence both the aforementioned dimensions are the mutual acceptance of roles, the relationship between the owner-manager and successor, and family harmony.  The continued profitability of the business is also influenced by the agreement to continue the business. The existence of family harmony in itself influences the relationship between the owner-manager and successor, the agreement to continue the business, as well as the mutual acceptance of roles.  The managerial implications of these empirical findings are discussed and recommendations offered.

    2016-04-01

    Full Text Available In China, a large number of small and medium-sized food enterprises (food SMEs rarely adopt the hazard analysis and critical control points (HACCP system, which results in a low product quality. Some local governments have encouraged food SMEs to implement HACCP systems through financial subsidies, but because of an incomplete understanding of the willingness to pay (WTP for implementing HACCP systems in food SMEs, relevant policies have not enhanced the adoption rate of HACCP systems. Based on our questionnaire survey data of 132 food SMEs in China's Henan, Guangdong, and Zhejiang provinces, this study estimates Chinese food SMEs' WTP for implementing HACCP systems by a double bounded dichotomous choice contingent valuation method (CVM. According to the estimated results, the WTP for implementing HACCP systems under the log-logistic model is approximately 115,714 Chinese RMB (113,149 Chinese RMB for the log-normal model.

    2002-04-03

    The purpose of this report is to document the development of the proof-of-concept units within the Advanced Medium-sized Mobile Power Sources (AMMPS) program. The design used a small, lightweight diesel engine, a permanent magnet alternator, power electronics and digital controls as outlined in the philosophy detailed previously. One small proof-of-concept unit was completed and delivered to the military. The unit functioned well but was not optimized at the time of delivery to the military. A tremendous amount of experience was gained during this phase that can be used in the development of any follow-on AMMPS production systems. Lessons learned and recommendations for follow-on specifications are provided. The unit demonstrated that significant benefits are possible with the new design philosophy. Trade-offs will have to be made but many of the advantages appear to be within the technical grasp of the market.

    2008-03-01

    The objective of this controlled intervention study was to investigate the effects of a 2-year training program in health and safety (H&S) management for managers at small- and medium-sized companies. A total of 113 managers of motor vehicle repair garages participated in the training and another 113 garage managers served as a comparison group. The effects were measured using questionnaires sent before and after the intervention to the managers and blue-collar workers at the garages. The intervention group managers reported significantly greater improvement of their H&S management system than the managers in the comparison group. The results also indicate that the management training positively affected how the workers regarded their supportive working environment. H&S management training may positively affect measures at both garage and individual levels.

    Agustín J Sánchez-Medina

    Full Text Available In the business context, concern for the environment began to develop when pressure from the public administration and environmental awareness groups raised the specific requirements for companies. The Theory of Planned Behavior considers that people's conduct is determined by the intention of carrying out a certain behavior. Thus, the individual's intent is determined by three factors related to the desired outcome of the behavior: the Personal Attitude toward the Results, the Perceived Social Norms, and the Perceived Behavioral Control over the action. Therefore, the objectives of this paper are to clarify the attitudes of the managers of Canarian small and medium-sized companies about taking environmental measures, and try to demonstrate whether there is a relationship between the proposed factors and the intention to take these measures.

    Directory of Open Access Journals (Sweden)

    Banjo G. Roxas

    2008-01-01

    Full Text Available This article proposes a conceptual framework that explains that the social capital of a community shapes the innovation performance of small and medium-sized enterprises (SMEs through knowledge management within the firm. The study's significance stems from the unprecedented effort in explaining how community social capital matters in the innovation performance of SMEs, a departure from previous studies that have typically examined market-related or hierarchical social capital in the form of formal networks and directly linked them to a firm's innovation performance without due regard for knowledge management within the firm as an antecedent of organisational innovation performance. The aim is to stimulate further thinking and empirical research on the subject of social capital of a community in the SME and/or entrepreneurial context.

    This study investigates the benefits and limits deriving from membership with ESA of six medium-sized space agencies in terms of strengthening and development (or not) of space technologies, as well as their contribution to the growth of productive activities and to the increase of services for citizens. This research contributes to the more general issue of the usefulness of space activities, not only for scientific or military-political purposes but also for economic and social development. Results show that, on the one hand, the membership with ESA has allowed smaller Countries to access space programs, to develop advanced technologies and to support the growth of their firms in some significant markets, but, on the other hand, the membership has also limited the access to space to few companies, without encouraging the broad dissemination of technological knowledge.

It focuses on the critical first and less risky step towards internationalization and separates the motivators into home country and host country. The paper investigates 44 specific, high impact, pre-selected exporting motivators from the literature and tests their effect on the firm’s initial export decision and latest (or sequential export decision. Results show that the first exporting choice affects later exporting choices and both are mostly affected by home country-specific, internal, motivators as opposed to host country-specific reactive motivators. In addition regionalization shows an association as European Union membership of the UK showed a relationship to subsequent entry mode choice. The paper’s results are of use to policy-makers and management.

    The successful deployment of a hydrogen delivery (transmission and distribution) infrastructure will be critical for the widespread use of hydrogen. Estimates based on three scenarios that vary in the degree of hydrogen penetration in the European energy system indicate that between 1 and 4 million km of distribution pipelines, and up to 35 000 km of high-pressure transmission and 400 000 km of medium pressure sub-transmission pipelines may be needed by 2050. A truck fleet for the supply of liquefied hydrogen may reach the size of 3000-8000 vehicles. The cumulative capital necessary to build this infrastructure by 2050 may range between 700 and 2200 thousand million euros for the most optimistic scenario and is significantly lower for the other scenarios. Most of this will be needed for the development of the distribution network. These costs however represent a relatively small fraction (7.5-22%) of the annual gross value added of the energy sector.

    Full Text Available The new EU-Accounting Directive of 26 June 2013 (DIRECTIVE 2013/34/EU has the intention to harmonize the accounting and financial reporting of enterprises in the European Union. “Think small first” is the central principle in the new EU-Accounting Directive and the new regulations have to be adopted in the laws of European member states by 20 July 2015. The International Financial Reporting Standard for Small and Medium-sized Entities (IFRS for SMEs was published in 2009 by the International Accounting Standards Board (IASB. The IASB intended to create simplified international financial reporting standards for the special needs of smaller and medium-sized enterprise. The IASB completed in May 2015 a comprehensive review of the IFRS for SMEs and made amendments to the Standard. The revised version of the IFRS for SMEs will be issued in the last quarter of 2015. The aim of the paper is to analyze the compatibility of the IFRS for SMEs and the new EU- Accounting Directive and the problems in connection with the harmonization of the European accounting legislation especially in Germany. Based on the results of the research most of the former incompatibilities could be removed, but the remaining complexity of the IFRS for SMEs and the lack of an option for the member states to adopt the IFRS for SMEs as an accounting and reporting standard besides or instead their local accounting principles will prevent the wide use of the IFRS for SMEs in Germany and in other member states of the European Union.

    Proper work environments are important for nurses to feel motivated. We examined the associations between work motivation and job satisfaction among Japanese nurses to improve their motivation. In Japan, relatively small and medium-sized private hospitals play a central role in the healthcare industry. In the present study, the subjects were nurses working in 23 small and medium-sized private hospitals that had 65 to 326 beds. We analyzed 1,116 registered and licensed practical female nurses (average age, 38.3 years; standard deviation, 11.3 years). Many nurses with their specialized nursing skills dedicate themselves to patient care. However, many of these nurses may not be interested in contributing to their hospitals. Nurses may have different opinions regarding dedication to patient care and contribution to their hospitals. Therefore, concerning work motivation, we produced these two different items, "Nurses' dedication to patients" and "Nurses' contribution to their hospitals." We also produced our own original new job satisfaction questionnaire. We found 7 facets of job satisfaction: "Work as specialists," "Workplace safety," "Relationships with superiors," "Work-life balance," "Relationships among nurses," "Communications with physicians," and "Salary." Multiple linear regression analyses show that both "Nurses' dedication to patients" and "Nurses' contribution to their hospitals" were significantly associated with "Work as specialists." Nurses feel their jobs of protecting people's lives and health are valuable. They do not feel motivated only by money. They value the intrinsic nature of their jobs. Creating proper work environments is important for nurses to be able to work as specialists.

  4. Occurrence of large and medium-sized mammals: Occurrence but not count models predict pronghorn distribution: Chapter 8

    2011-01-01

    Management of medium to large-sized terrestrial mammals (Antilocapridae, Canidae, Cervidae, Leporidae, Mustelidae, Ochotonidae) in the western United States is multifaceted and complex. Species in this group generally are charismatic and provide economic opportunities, although others are considered a nuisance at one extreme or are listed as species of conservation concern at the other. Understanding the relative influence of land cover, habitat fragmentation, and human land use on their distribution during the breeding season is imperative to inform management decisions on land use and conservation planning for these species. We surveyed medium to large-sized sagebrush (Artemisia spp.)-associated mammal species in 2005 and 2006 on 141 random transects (mean length = 1.1 km) in the Wyoming Basins, an area undergoing rapid land cover transformation due to human actions including energy development. Overall, we observed 10 species but only obtained enough observations of pronghorn (Antilocapra americana) to develop spatially explicit distribution models. For pronghorn, occurrence related positively to proportion of sagebrush land cover within 0.27 km, mixed shrubland land cover within 3 km, riparian land cover within 5 km, Normalized Difference Vegetation Index (NDVI) within 0.27 km, road density within 5 km, and decay distance to power line corridors at 1 km, but negatively to salt-desert shrubland cover within 18 km and an interaction between sagebrush and NDVI within 0.27 km. We found excellent predictive capability of this model when evaluated with independent test data. The model provides a basis for assessing the effects of proposed development on pronghorn and can aid planning efforts to avoid or mitigate adverse effects on pronghorn.

    The meso-scale landscape dynamics model, CALEROS, has been developed to simulate the interactions between climate, soil production and erosion, vegetation and land use on geomorphological to human time scales in Mediterranean environments. Starting from an initial landscape consisting of a DTM, soil distribution and underlying lithology, the landscape is free to develop in response to the imposed climate variability and seismicity. In addition to changes in soil distribution and bedrock lowering, this includes the establishment of vegetation as conditioned by a selection of plant functional types and, optionally, population and land use dynamics as conditioned by land use scenarios specifying technological and dietary constraints for different periods. As such CALEROS is well-suited to investigate the relative impacts of climate, land cover and human activities on the hydrological catchment response and the associated sediment fluxes due to soil erosion and mass movements. Here we use CALEROS to i) investigate the redistribution of water and sediment across the landscape in a medium-sized Mediterranean catchment (Contrada Maddalena; ~14km2, Calabria, Italy) and ii) to establish patterns of co-evolution in soil properties and vegetation under pristine and anthropogenically impacted conditions on a millennium-scale. Using summary statistics to describe the emergent properties and to verify them against observations, we then delineate areas of uniform morphology and describe the various pathways of development. This information allows us to identify elements of consistent hydrological response and the associated transfer of material across different scales. It also provides essential information on essential feedbacks and the resulting convergence or divergence in landscape development under the impact of climatic or seismic events or human intervention. Although the results are evidently conditioned by the physiographic setting of the study area and by the

    Full Text Available This study sought to establish the social and environmental factors that influence sustainable entrepreneurship (SE in Small- and medium-sized enterprises (SMEs. It also attempted to identify whether the demographic background of the entrepreneur influences the SE in SMEs of the Iranian food industry. A mixed method approach, employing the use of questionnaires and interviews from a sample size of approximately 130 participants and 12 owner-managers of SMEs in food industry, was used to collect data. Data were analyzed using descriptive statistics and several inferential analyses. Findings showed that certain characteristics of the entrepreneur, including work experience and education, have a significant impact on SE. Furthermore, out of the eight identified factors, according to the participants’ perception, the most important factors towards sustainable performance of SMEs in food industry are social factors, including customer orientation, as well as human resources and environmental factors, including recycling and the future of Earth. This research paper concludes that considering the social and environmental aspects of sustainability and employing experienced staff would majorly contribute to the pursuit of SE in SMEs of food industry.

  7. Presenting a Framework to Analyze Local Climate Policy and Action in Small and Medium-Sized Cities

    Full Text Available Academic attention to local climate policy usually focuses on large-sized cities. Given the climate challenges ahead this seems unjustified. Small and medium-sized cities (SMCs deserve scholarly attention as well. The main question is: What factors influence climate change policy and local climate actions in SMCs? In this article we present an analytical framework to analyze climate change policy and local climate actions of SMCs. The framework addresses different aspects: policy-input, -throughput, -output, -outcome, characteristics of the local environment, local action arenas, influence by higher government levels, and interaction with climate change issue networks. The framework is used to analyze and compare four case studies of SMCs in the Dutch region of Twente (two urban and two rural municipalities, and addresses both adaptation and mitigation. Results show that both ‘localist’, ‘multi-level’ and issue network membership factors influence local climate policy action. Governance modes discerned concern mostly ‘governing by authority’ and ‘self-governing’. When reflecting on the role of SMCs in climate action the study revealed the importance of local capacity building schemes issued by provincial government, inter-municipal network collaboration, and the potential for local governments to mobilize and organize citizen action.

    Peptides have recently become attractive for therapeutic applications. However, efficient production of medium- to large-sized peptides (30-100 amino acids [aa]) remains challenging both by recombinant and chemical synthesis. We previously reported the formation of active enzyme aggregates in Escherichia coli cells induced by the short β-structured peptide ELK16 (LELELKLKLELELKLK) and developed a streamlined protein expression and purification approach. In this approach, a cleavable self-aggregating tag (cSAT) consisting of an intein molecule and ELK16 was used to release the recombinant peptides with reasonable purity from active aggregates. In this work, we extended the cSAT approach to a generalized expression and purification solution for a set of medium- to large-sized peptides with important therapeutic uses, including human glucagon-like peptide 1 (31 aa), B-type natriuretic peptide (32 aa), exendin 4 (39 aa), chemokine (C-C motif) ligand 5 (also known as RANTES, 66 aa), stromal cell-derived factor 1α (67 aa), insulin-like growth factor 1 (70 aa), and leptin (146 aa). After intein-mediated cleavage, the soluble peptides were released directly into the supernatant while insoluble peptides could be refolded and purified by reverse phase high-performance liquid chromatography. Additionally, an N-terminal thioredoxin tag was added upstream of the target peptides, which can be removed by enterokinase cleavage, generating native N-terminus for target peptides. Final yields of the peptides ranged from 0.1 to 1.8 μg/mg wet cell weight at laboratory scale. The approach described in this study provides a fast and efficient route to express and purify peptides that are difficult or expensive to produce by chemical synthesis or by ordinary recombinant methods. It is particularly well suited for large peptides, peptides likely to be degraded, and peptides that have toxic effects on the host. It can greatly reduce the cost and time of downstream processing, and thus

    Full Text Available This paper aims to highlight, from a marketing perspective, the manner and conditions in which small and medium-sized enterprises can use modern management methods in planning the marketing activity. Using modern methods of management are particularly important for managers of these organizations and especially for marketers. Thus, the following methods play a significant role within the marketing activitiesn#8217; development for marketing specialists, namely: management by objectives, management by budgets, management by projects, and management by product. The high degree of understanding and using the above methods is, in the current economic environment, one of the determinants of the market success of small and medium-sized enterprises. In the current context, the adoption of the management by objectives is not a facultative option for the small and medium-sized enterprises, but rather a binding one in the context of adopting and practicing an efficient marketing with significant results on the development of marketing programs comprised within them. Similarly to the management by objectives, the use of the management by budgets within the small and medium-sized enterprises has a series of features required by their smaller size, features that should be considered by marketers. Regarding the use of management by projects, this method has to constitute the foundation for the elaboration of marketing programs developed within the small and medium-sized enterprises, thereby allowing shaping an action that can be accompanied by success in achieving the goals comprised within the marketing programs. Finally, the role of the management by product is extremely important in the marketing activity within the small and medium-sized enterprises, especially in the operationalization of concepts such as strategic marketing and tactical marketing. This paper thus outlines from a marketing point of view the main issues aiming at understanding and using

    Full Text Available In modern conditions the region's sustainable development and economic growth is largely determined by its ability to implement innovations. One of the determining factors of long-term economic development of the territories, to date, is innovation. A mechanism to give impetus to the innovative development of the regions is to create effective small and medium-sized innovative enterprises. Voronezh region, like many Russian regions, has considerable potential for innovation, but usually it is not used efficiently or not used at all. The article deals with the concept and the need to develop innovative entrepreneurship and the role of small and medium innovative enterprises in the formation of scientific and technical potential of the Voronezh region. The basic conditions and factors promoting and impeding the development of small and medium innovative businesses in the region, determined the willingness of subjects of innovation activity in the development, implementation and promotion of innovation in the region.

    Full Text Available Objective of this article is to determine possible effect of product innovations on the financial performance of small and medium-sized enterprises in the Czech Republic. The pilot research has been realized on the statistical sample of 100 companies which were categorized into three basic groups; service companies, trade companies, and production companies. As the measure of innovation effect, the authors applied the deviation of production power, i.e. the ration of EBIT to assets, of a business entity from the industry average while the industry average of production power was selected especially in order to reduce the influence of the economy cycles. In the three categories of companies, different effects of product innovations have been observed. In the service companies and trade companies, the positive effect is limited because of potential simplicity of imitation by competitors. More positive effect of product innovations has been observed in production companies which can protect the products or production processes better then service companies or trade companies where the product innovations are mostly connected with extension of extension of services portfolio offered. For the conclusion, the authors provide suppositions and designs for their future research in this problem of innovations’ effectiveness measurement.

    2015-08-01

    The completeness of buildings in OpenStreetMap (OSM) is estimated for a medium-sized German city and its surroundings by comparing the OSM data with data from an official building cadastre. As completeness measures we apply two unit-based methods that are frequently applied in similar studies. It is found that the estimation of OSM building completeness strongly differ between the methods. A count ratio (number of OSM buildings / number of reference buildings) tends to underestimate the actual building completeness and an area ratio (total OSM building area / total reference building area) instead tends to overestimate the completeness within the study area. It is argued that a simple pre-processing of the building footprint polygons leads to a more accurate completeness estimation when applying the count ratio. It is also suggested to more carefully examine the areas that have been mapped in OSM but not in the reference data set (false positives). In the present study region, these values are mainly due to simplified OSM polygons and they contribute to an overestimation of the OSM building completeness when applying the area ratio.

    2010-12-01

    Full Text Available Small and medium-sized companies are an important part of today’s world economy, for their ability to offer new jobs but also for their capacity of innovation. At the same time, they are in a constant struggle with larger companies that take advantage of their negotiating power to impose their way of doing business to the SMEs. In an ICT enabled world, most large companies being intense ICT users, the lag of ICT adoption in SMEs may create a strong barrier between SMEs and large companies, promoting an over growing digital divide, the SMEs being in danger of being left out in some economic sectors. This paper aims at finding a possible solution in the Software-as-a-Service and Cloud Computing model, a rather new solution, yet more and more sought off by SMEs but also larger companies, especially considering the global financial and economic crisis, as well as evaluating the European Union’s main views and policies regarding the SAAS – Cloud model.

    Full Text Available In order to determine the organizational-economic and accounting aspects of franchising in the context of volatility of the macro-economic situation and the scarcity of entrepreneurs’ own funds, the current status of the franchising market in Ukraine, its economic essence and its role have been determined; the kinds of franchising that are known in world business practices have been provided; the types of distribution contracts that are close to the meaning of franchising have been defined; the legislative basis for franchising in Ukraine has been presented; the binding terms of a commercial concession contract as a legislated analogy of franchising in Ukraine have been determined; the features of reflection of the legality of franchising in accounting of both franchiser and franchisee have been provided. The objective advantages of franchising for both the large enterprises and the start-up entrepreneurs have been determined. On the basis of the legal nature of franchising relations in the accounting accounting, its reflection is close in the meaning to intangible assets. Implementation of franchising potential as a strategic tool for the development of small and medium-sized businesses requires the improvement of its legislative framework in the part of enhancing the responsibility of the parties.

    2015-02-01

    Full Text Available The manufacturing of medium-sized hollow parts using a foamed high density polyethylene was studied using a conventional accumulator blow extrusion machine and a systematic capture of pictures during the parison formation. To fully monitor the parison formation, several experiments were carried out varying the chemical foaming agent content from 0 wt.% to 2 wt.% and increasing the push extrusion speed. Results pointed out greater wall thickness, diameter, and length of parisons with higher weight percentage of blowing agent and extrusion speed. A full experimental characterisation of parison dimensions was essential to assure a proper prediction of the blowing step. Information was used as input for modelling and simulations of the blowing phase of an industrial container. To validate the proposed methodology, a blow moulding process of a generic container was simulated using Ansys Polyflow v13 software and its finite element analysis which provided an accurate approximation of the wall thickness expected. Further real tests on the simulated container also demonstrated that, in those parisons with a 1 wt.% CFA concentration and higher blowing pressure, there was remarkable improvement on their packaging properties such as decreasing of the total weight of the container and an enhancement of its surface quality.

  16. The possible ways to IFRS (International Financial Reporting Standards for SME (Small and Medium sized Entities development

    2007-01-01

    Full Text Available The most business entities in Europe are small or medium-sized enterprises (SME, which have a legal obligation to prepare financial statements in accordance with a set of accounting principles accepted in their country. Those statements are available to creditors, suppliers, and national governments but they could be badly understandable to creditors, suppliers and subjects in other countries. This is a great obstacle of their activities in the EU internal market. The existence of 27 different national accounting systems in the EU can be held for the most important obstacle.There are many ways how to develop compatible accounting standards for SMEs but the most significant activity in this field is the research project of IASB (International Accounting Standards Board. IASB has developed IFRS (International Financial Reporting Standards. Even though IFRS are suitable for all enterprises, their application in case of SMEs would be very expensive and could significantly increase compliance costs of taxation. This development has not been finished yet and there are still some problems which need to be solved before the introduction of accounting standards to the public. The research has shown that IFRS for SMEs should be used mainly by the entities which do not have public accountability – i.e. that its equities are not publicly traded and do not hold assets in a fiduciary capacity for a broad group of outsiders. This paper discusses those IFRS modifications, which should be done in case of SMEs.

    Full Text Available Corporate social responsibility (CSR has become increasingly important to the competitiveness of small and medium-sized enterprises (SMEs. A positive relationship between the CSR activities of SMEs and their enhanced competitiveness exists, at least if a long-term perspective is adopted (European Competitiveness Report, 2008:106; Mandl & Dorr, 2007:2. Despite the widespread practical and academic interest in CSR and its impact on the competitiveness of SMEs, few theoretical and empirical contributions could be found. The primary objective of this study was to identify and empirically test the CSR factors influencing the competitiveness of SMEs in Uganda. The outcomes of this study will assist SMEs to effectively and responsibly manage their activities to increase their competitiveness. A structured, self-administered questionnaire was distributed to 750 potential SME respondents. The respondents were identified by means of a purposive sampling technique, and the data were collected from 383 usable questionnaires. An exploratory factor analysis was carried out, and Cronbach’s alpha coefficients calculated to determine the discriminant validity and reliability of the measuring instrument. Correlations were assessed using structural equation modeling. The empirical results of this study indicate that workforce-oriented CSR activities, society-oriented CSR activities, market-oriented CSR activities and regulated CSR activities significantly influence the competitiveness of SMEs.

    Advanced therapy medicinal products (ATMPs) are gene therapy, cell therapy, and tissue engineered products. To gain access to the market within the European Union, ATMPs must be authorized by the European Commission (EC). Especially for small and medium-sized enterprises (SMEs), the European centralized procedure of marketing authorization that is conducted by the European Medicines Agency (EMA) constitutes a major challenge, because SMEs often have little experience with regulatory procedures and many have limited financial possibilities. To tackle these challenges, a certification procedure exclusively for SMEs and their ATMP development was introduced by the EC. Independently from a marketing authorization application, development and/or production processes can be certified. An issued certificate demonstrates that the respective process meets the current regulatory and scientific requirements of the EMA, representing a valuable milestone for putative investors and licensees. This article highlights the background, the detailed procedure, the minimum requirements, as well as the costs of certification, while giving further noteworthy guidance for interested parties.

    2012-08-01

    The smooth running of small and medium-sized manufacturing enterprises (SMEs) presents a significant challenge irrespective of the technological and human resources they may have at their disposal. SMEs continuously encounter daily internal and external undesirable events and unwanted setbacks to their operations that detract from their business performance. These are referred to as `disturbances' in our research study. Among the disturbances, some are likely to create risks to the enterprises in terms of loss of production, manufacturing capability, human resource, market share, and, of course, economic losses. These are finally referred to as `risk determinant' on the basis of their correlation with some risk indicators, which are linked to operational, occupational, and economic risks. To deal with these risk determinants effectively, SMEs need a systematic method of approach to identify and treat their potential effects along with an appropriate set of tools. However, initially, a strategic approach is required to identify typical risk determinants and their linkage with potential business risks. In this connection, we conducted this study to explore the answer to the research question: what are the typical risk determinants encountered by SMEs? We carried out an empirical investigation with a multi-method research approach (a combination of a questionnaire-based mail survey involving 212 SMEs and five in-depth case studies) in New Zealand. This paper presents a set of typical internal and external risk determinants, which need special attention to be dealt with to minimize operational risks of an SME.

  20. Conducting Creativity Brainstorming Sessions in Small and Medium-Sized Enterprises Using Computer-Mediated Communication Tools

    Murthy, Uday S.

    A variety of Web-based low cost computer-mediated communication (CMC) tools are now available for use by small and medium-sized enterprises (SME). These tools invariably incorporate chat systems that facilitate simultaneous input in synchronous electronic meeting environments, allowing what is referred to as “electronic brainstorming.” Although prior research in information systems (IS) has established that electronic brainstorming can be superior to face-to-face brainstorming, there is a lack of detailed guidance regarding how CMC tools should be optimally configured to foster creativity in SMEs. This paper discusses factors to be considered in using CMC tools for creativity brainstorming and proposes recommendations for optimally configuring CMC tools to enhance creativity in SMEs. The recommendations are based on lessons learned from several recent experimental studies on the use of CMC tools for rich brainstorming tasks that require participants to invoke domain-specific knowledge. Based on a consideration of the advantages and disadvantages of the various configuration options, the recommendations provided can form the basis for selecting a CMC tool for creativity brainstorming or for creating an in-house CMC tool for the purpose.

    Full Text Available Currently, innovations seem to be a crucial process in companies in order to at least maintain or even improve their competitiveness. Strengthening global competition puts the stress on continual improvements in every sphere of business entity’s activities. This way, innovations are the almost only tool to maintain customers, subsequently to keep the place on a market or the market share, and then to sustain the financial performance of a company. It means that effect of innovations is closely connected with the financial performance of a business entity that can be measured with various methods or approaches while the financial analysis ratios are supposed to be basic ones. In order to interpret the results of these financial ratios, different bases are used when the base of financial plan is one of them. The objective of this article is to determine the economic effect of innovations on financial performance of small and medium-sized enterprises in the Czech Republic on the base of simplified financial plan. Obviously, starting-point of the financial plan preparation is the plan of sales. Sales represent one of the company’s value generators, and sales projection is constituted as basis of authors’ approach to determination of effect of innovations on financial performance of business entities while basic categorization of companies according to the business branch (CZ NACE, sphere of innovation and innovation’s degree is applied.

    This paper aims to analyse the evolution experienced by the neighbourhoods that comprise the so-called first periphery. Most of them have been thoroughly studied, has led to recognize theirs values and to be included in the catalogues of heritage protection of their respective cities. However, this research shows that is pending an in-depth analysis in cities of intermediate scale. Its significance lies not only in the fact that they are the most significant operations of architecture of the modern movement in their respective cities, but are especially noteworthy the values derived from its strategic location within the urban structure of these intermediate scale cities. Being near to city centre, they have been constituted as transition pieces between historic sites, new peripheral developments, and even, their nearest territory. As method, this research proposes a comparative analysis of traceability among different study cases, from medium-sized cities of the Andalusian Coast (Spain). In this context, it means recording the evolution that these promotions have been experienced since their first designs until their current situation. It attempts to find the characteristics that have resulted in the urban configuration of this periphery and to recognize the sum of all the cultural, economic, social and technological aspects that conditions the ways of life that today are detected in them. Definitely, the knowledge generated by this research allows extracting architectural and urban values of these examples, which justify its necessary dissemination as part of our legacy.

    Full Text Available When employed in a focused manner, corporate performance evaluation has proven to be instrumental for entrepreneurs as an important tool that contributes with performance improvements at their organizations. The descriptive study herein, prepared as of a questionnaire comprising 46 queries, poses to analyse the performance of micro and small companies (MSEs by employing the multicriteria methodology for constructive decision aiding (MCDA-C. As of respondent replies, MCDA-C descriptors were formed, shaping six prime groups so as to identify relevant factors that drive or hinder MSE success. The questionnaire was applied to managers in charge administering 25 small and medium-sized companies of Lages, a city within the Brazilian state of Santa Catarina. Study findings provide evidence as to the fact that (i 24% of surveyed companies, tend to go bankrupt; (ii managerial functions at the MSEs are the prime source of influence on negative outcomes; (iii from a financial control standpoint, surveyed companies fall far shorter than the minimum level deemed necessary to qualify as satisfactory; (iv those that present the best results, operate both within the domestic and international markets; (v the study placed under the spotlight the group “Evolution Stage”, evidencing the trend of ever increasing MSE expansion. This study revealed that corporate failure contributing factors are intensely interconnected and largely depend on the entrepreneur´s own performance, the prime contribution of findings residing in demonstrating that MCDA-C can be employed to analyse the performance of micro and small businesses.

    Full Text Available The business environment is currently characterized by intensified competition at both the national and firm levels. Many studies have shown that innovation positively affect firms in enhancing their competitiveness. Innovation is a dynamic process that requires a continuous, evolving, and mastered management. Evaluating the sustainability of overall innovation capability of a business is a major means of determining how well this firm effectively and efficiently manages its innovation process. A psychometrically valid scale of evaluating the sustainability of overall innovation capability of a firm is still insufficient in the current innovation literature. Thus, this study developed a reliable and valid scale of measuring the sustainability of overall innovation capability construct. The unidimensionality, reliability, and several validity components of the developed scale were tested using the data collected from 175 small and medium-sized enterprises in Iran. A series of systematic statistical analyses were performed. Results of the reliability measures, exploratory and confirmatory factor analyses, and several components of validity tests strongly supported an eight-dimensional (8D scale of measuring the sustainability of overall innovation capability construct. The dimensions of the scale were strategic management, supportive culture and structure, resource allocation, communication and networking, knowledge and technology management, idea management, project development, and commercialization capabilities.

    Full Text Available Small- and medium-sized enterprises (SMEs are the important driving forces for the growth of China’s economy. However, financing difficulty has always been the important problem besetting the development of SMEs for a long time. In particular, in recent years, US subprime crisis in 2008 caused a heavy blow to the development of some externally oriented SMEs. Thus, how to effectively overcome financing predicament for the SMEs is crucial for Chinese government. In this paper, based on microdata from China Industrial Enterprise Database, propensity score matching (PSM method is adopted to conduct empirical analysis about the treatment effects of indirect financing level of SMEs under different systems. Empirical results reveal that state-owned enterprises enjoy indirect financing advantages compared with other enterprises and there is certain ownership discrimination against foreign-funded enterprises and private enterprises. In particular, the indirect financing rate of state-owned enterprises is 1.4% higher than that of other enterprises, and the indirect financing rate of foreign-funded enterprises is 6% lower than that of other enterprises; private enterprises are advantageous in indirect financing compared with other enterprises; however, indirect financing rate of private enterprises is 1.8% lower than that of state-owned enterprises, which also reveals ownership discrimination to certain extent.

    Full Text Available The diversity of Brazilian vertebrates is regarded among the highest in the world. However, the biologicaldiversity is still mostly unknown and a good part of it is seriously threatened by human activities. This study aimed toinventory the medium and large size mammals present in the Reserva Biológica de Santa Rita do Sapucaí, an Atlanticforest reserve located in Santa Rita do Sapucaí, southeastern Brazil. Sand-plots, photographic traps and searches foranimal tracks on pre-existent trails in the area, were carried out once every two months between May 2006 andFebruary 2007. The sand-plots and tracks were inspected during five consecutive days per sampling. We obtained 108records of 15 species, mostly of carnivorans. Two confirmed species are threatened with extinction in Brazil (Callithrixaurita and Leopardus pardalis. The results suggest that the sampled reserve has high species richness and plays animportant role in conservation of mammals in this landscape, including species threatened with extinction.

    Following a recent trend of scientific studies on artwork, we study here the thermodynamics of a jetting thermometer made of ceramic, related to the Chinese tea culture. The thermometer represents a boy who "urinates" shortly after hot water is poured onto his head. Long jetting distance indicates if the water temperature is hot enough to brew tea. Here, a thermofluid model describes the jetting phenomenon of that pee-pee boy. The study demonstrates how thermal expansion of an interior air pocket causes jetting. The validity of assumptions underlying the Hagen-Poiseuille flow is discussed for urethra of finite length. A thermodynamic potential is shown to define maximum jetting velocity. Seven optimization criteria to maximize jetting distance are provided, including two dimensionless numbers. The dimensionless numbers are obtained by comparing the time scales of the internal pressure buildup due to heating, with that of pressure relief due to jetting. Optimization results show that longer jets are produced by large individuals, with low body mass index, with a boyhood of medium size inclined at an angle π/4. Analogies are drawn with pissing contests among humans and lobsters. The study ends by noting similitudes of working principle between that politically incorrect thermometer and Galileo Galilei's thermoscope.

  9. An Influence of Strategic Awareness on Management Control: Evidence from Polish Micro, Small and Medium-sized Enterprises

    Full Text Available Purpose: The paper investigates whether employees’ strategic awareness influences the shape of management control systems (MCSs in Polish micro, small and medium-sized enterprises (mSMEs. Methodology: The study is based on data obtained from 223 companies between November 2010 and January 2012. The quantitative analysis used a set of variables which depicted MCSs: ‘goalsetting process’, ‘control framework’ and ‘organisation of control’. Strategic awareness was considered an independent variable. Findings: The results showed positive correlations between strategic awareness and considered variables. Regression models developed by the authors proved statistically valid. The study evidences, that increasing employees’ strategic awareness stimulates their participation in goal-setting, contributes to the development of more comprehensive MCSs, or may even imply formalisation of management control. Research limitations: The study does not include an analysis of the extent to which employees find MCSs useful in their work. This will be considered in future research. Another possible extension of the project is to identify factors which enable the capturing of the dynamic character of MCSs and their changes over time. Practical implications: The knowledge of MCSs does not explain whether or not the strategic orientation of a company stimulates a need for MCS. Such knowledge may be important to managers who have to face Polish employees’ general aversion to control. Originality: The study contributes to the limited body of knowledge in a scope of relations between employees’ strategic awareness and control mechanisms in Polish mSMEs.

  10. An Initial Implementation of Multiagent Simulation of Travel Behavior for a Medium-Sized City in China

    2014-01-01

    Full Text Available Since the traditional four-step model is so simple that it cannot solve complex modern transportation problems, microsimulation is gradually applied for transportation planning and some researches indicate that it is more compatible and realistic. In this paper, a framework of agent-based simulation of travel behavior is proposed, which is realized by MATSim, a simulation tool developed for large-scale agent-based simulation. MATSim is currently developed and some of its models are under training, so a detailed introduction of simulation structure and preparation of input data will be presented. In practice, the preparation process differs from one to another in different simulation projects because the available data for simulation is various. Thus, a simulation of travel behavior under a condition of limited available survey data will be studied based on MATSim; furthermore, a medium-sized city in China will be taken as an example to check whether agent-based simulation of travel behavior can be successfully applied in China.

    Traffic is the major air pollution source in most urban areas. Nowadays, most of the strategies carried out to improve urban air quality are focused on reducing traffic emissions. Nevertheless, acting locally on urban design can also reduce levels of air pollutants. In this paper, both strategies are studied in several scenarios for a medium-sized town of the Basque Country (Spain). Two main actions are analysed in order to reduce traffic emissions: (1) minor extension ofa pre-existing low emission zone (LEZ); (2) substitution of 10% of passenger cars that are older than 5 years by hybrid and electric vehicles. Regarding local urban design, three alternatives for the development of one side of a street canyon are considered: (1) a park with trees; (2) an open space without obstacles; (3) a building. Two different urban traffic dispersion models are used to calculate the air quality scenarios: PROKAS (Gaussian&box) to analyse the reduction of traffic emissions in the whole urban area and WinMISKAM (CFD) to evaluate specific urban designs. The results show the effectiveness of the analysed actions. On one hand, the definition of a small LEZ, as well as the introduction in 2015 of vehicles with new technology (hybrid and electric), results in minor impacts on PM10 and NO2 ambient concentrations. On the other hand, local urban design can cause significant variation in spatial distribution ofpollutant concentrations emitted inside street canyons. Consequently, urban planners should consider all these aspects when dealing with urban air pollution control.

    Full Text Available We live in a complex world and managers of organizations are constantly facing numerous challenges. Good decisions, i.e., better outcomes for organizations, require use of the powerful discipline Operational Research (OR/Management Science (MS. Organizations applying this discipline have achieved significant benefits such as cost reduction, increased revenues, increased market share, higher quality, improved productivity, improved performance, better customer service, etc. The aim of this paper is to examine whether managers of micro, small and medium-sized enterprises in Macedonia use OR models for supporting decision-making processes, where OR models, methods and techniques are commonly used, and what benefits achieved in using quantitative OR models, methods and techniques. The survey was conducted using a questionnaire distributed electronically to 100 managers of micro, 100 managers of small and 100 managers of medium-sized enterprises. The questionnaires were answered completely by 93 managers of the micro, 73 managers of the small and 71 managers of the medium-sized enterprises, and the questionnaire responses were subsequently analyzed. The answers showed that decisions on running enterprises are made intuitively by 90% of managers of the micro, 78% of managers of the small, and 55% of managers of the medium-sized enterprises, while quantitative OR models for supporting the decision-making process are used by 10% of managers of the micro, 22% of managers of the small, and 45% of managers of the medium-sized enterprises. Applied in the micro, small and medium-sized enterprises are inventory models, time series analysis and forecasting, whereas micro and medium-sized enterprises rely on decision analysis. Small and medium-sized enterprises use break-even analysis, assignation, linear programming, and project management. The OR models and methods used in running the respective enterprises led to the following results: optimal inventory

    The German Prevention Act, the main parts of which came into force on 25 July 2015, encourages health promotion and prevention programs for people in their living environment. Through this act, preventive measures could reach employees at work that hardly seek medical services. This is of importance since employees with a low occupational position often show risk factors that increase morbidity and mortality. In this study, clinical data from n = 2280 employees from small and medium sized enterprises (SME) were analyzed for economic sector, sex, socioeconomic position (SEP), economic sector cardiovascular risk factors, musculoskeletal and psychological diseases. The socioeconomic position was categorized using the European Socioeconomic Classification into an intermediate/high and a low SEP category. Male employees showed a significantly higher occurrence of risk factors, such as smoking, diabetes or hypertension in comparison to female employees. In the manufacturing industry, male employees with a low SEP showed a higher prevalence of diabetes (2.3 vs. 5.9%), smoking (27.4 vs. 46.5%), and physical inactivity (sports: 55.0 vs. 37.1%) in comparison to employees with an intermediate/high SEP. Male employees with a low SEP from health and social services reported psychiatric disorders more frequently in comparison to those with an intermediate/high SEP (0.7 vs. 5.9%). Male employees with a low SEP should be given special consideration in the implementation of preventive measures at work within the framework of the Prevention Act.

    It is important to perform the first 12 weeks of rehabilitation without risk of tearing a cuff tendon from its repair site. Our hypothesis was that performing early postoperative rehabilitation with a limitable pendulum exercise device can produce lower retear rate outcomes when it is combined with safe, informed physiotherapy compared with a standardized protocol of rehabilitation performed at home. By using an asymmetric arm support brace and an advanced accelerometer, we attempted to determine the benefits of small pendulum exercises (proposed by Long et al). This study enrolled 24 patients to use a monitoring device in standardized small pendulum exercises. Clinical outcomes and magnetic resonance images were evaluated preoperatively and 12 weeks after surgery. While a patient performed pendulum exercises, a therapist used computer imagery to observe whether vertical acceleration was over a given threshold (identified as physiologic tremors), as a warning of and precaution associated with the increased risk of repair failure. Similar self-reported functional outcomes were reported in 2 areas. The rate of recurrent tears was significantly higher for both the medium-sized and large areas in the uninformed home rehabilitation group compared with the informed group. The results of monitoring of pendulum exercises to develop informed physical therapeutic methodology were consistent with those of previously published literature. In this study, use of a monitoring device during early rehabilitation was associated with lower retear rates after rotator cuff repair.

    Background: The incidence and findings of tuberculous invasion of the peripheral bronchus have not been fully investigated with MDCT. Purpose: To evaluate the prevalence and findings of MDCT abnormalities of small- and medium-sized bronchus (SMB) in active pulmonary tuberculosis (TB). Material and Methods: Using multiplanar reformation, 35 consecutive MDCT scans (follow-up exams available in 14 patients with a mean interval of 8.1 months) were assessed for following abnormalities of SMB: bronchial impaction (BI), wall thickening, dilatation, peribronchial cuff of soft tissue, and bronchocavitary fistula. It was also assessed whether tree-in-buds (TIB) have a tendency to distribute in the territories of diseased SMB, and whether SMB abnormalities are present in patients with relatively mild disease. Results: SMB abnormalities were observed in 23 (65.7%) patients with active TB. The most frequent finding was wall thickening (n=18, 51.4%), followed by BI (n=13, 37.1%; zigzag-shaped in four), dilatation (n =11, 31.4%), amputated appearance of air column (n=11, 31.4%), peribronchial cuff of soft tissue (n=10, 28.6%), and bronchocavitary fistula (n=8, 22.9%). TIB (n=29; absent in two patients with SMB) was mainly within (n=14) or close to (n=4) the territory of diseased SMB. Follow-up CT frequently showed improvement of wall thickening (11/12) and persistence of bronchial dilatation (11/13). SMB abnormality was present in all of six patients with mild disease. Conclusion: MDCT shows that tuberculous invasion of the peripheral bronchus may be more frequent than previously thought, of which findings include wall thickening, BI, dilatation, amputated appearance of air column, peribronchial cuff of soft tissue and bronchocavitary fistula

    Full Text Available Objective: The paper aims to assess the use of the potential of business environment institutions to support SMEs in the light of the author's own research. Research Design & Methods: The author's study was carried out in 2012-2014 in two stages: quantitative research (a survey on the sample of 590 SMEs conducted with the use of the PAPI and CAWI methods based on a survey questionnaire and qualitative research conducted among 10 representatives of business environment institutions with the use of in-depth interviews (IDI based on a questionnaire with a standard list of information sought. Findings: The study results suggest that the role of business environment institutions in the development of small and medium-sized enterprises in the present conditions is small. This is a result of, on the one hand, little interest of SMEs in the support offered by these institutions, and, on the other hand, the fact that frequently the services offered do not meet the needs of enterprises. Implications & Recommendations: To improve the situation, on the part of business environment institutions, it is necessary to update information on the scope of cooperation, undertake extensive promotional activities, adjust the offer to the needs of enterprises and expand cooperation, especially by providing financial support for enterprises. Contribution & Value Added: The study can be used for in-depth analyses of support for the SMEs provided by business environment institutions. It can be also useful for decision-makers responsible for creating development policies.

    Full Text Available Orientation: The paper investigates the situation facing SME’s in Nigeria, who have to function in an environment with depleted infrastructure.Research purpose: To examine the effects of infrastructure deficiency on the performance of manufacturing small and medium sized enterprises in Nigeria.Motivation for the study: Low budgetary allocation by the Nigerian government toward investment and rehabilitation of infrastructure in favor of attempts to conform to the tenets of trade liberalisation, has created a situation where basic infrastructure provision is a huge challenge in the creation of SME’s.Research design, approach and method: A longitudinal approach was followed, where a survey was conducted amongst 500 SME’s in Nigeria. To complement this, semi-structured interviews were conducted in 2007 and 2011 respectively. Main findings: The deficiency in infrastructure negatively impacts the profitability and performance of SMEs, due to the high cost incurred by SMEs in the self-provision of infrastructure and distribution of finished goods. Furthermore, despite the successful privatisation of electricity production in November 2013, there is still no significant improvement in the power supply in Nigeria. However, the government has embarked on road rehabilitation to ease the transportation of goods and services.Practical/managerial implications: The study uncovers the practical realities of the challenges faced by SME’s operating in an environment with insufficient infrastructure, which is typical of much of the developing world.Contribution/value add: The study highlights the necessity of sound infrastructure provision as a key factor to the development of SME’s.

    There is a demonstrable association between exposure to air pollutants and deaths due to cardiovascular diseases. The objective of this study was to estimate the effects of exposure to sulfur dioxide on mortality due to circulatory diseases in individuals 50 years of age or older residing in São José dos Campos, SP. This was a time-series ecological study for the years 2003 to 2007 using information on deaths due to circulatory disease obtained from Datasus reports. Data on daily levels of pollutants, particulate matter, sulfur dioxide (SO{sub 2}), ozone, temperature, and humidity were obtained from the São Paulo State Environmental Agency. Moving average models for 2 to 7 days were calculated by Poisson regression using the R software. Exposure to SO{sub 2} was analyzed using a unipollutant, bipollutant or multipollutant model adjusted for mean temperature and humidity. The relative risks with 95%CI were obtained and the percent decrease in risk was calculated. There were 1928 deaths with a daily mean (± SD) of 1.05 ± 1.03 (range: 0-6). Exposure to SO{sub 2} was significantly associated with mortality due to circulatory disease: RR = 1.04 (95%CI = 1.01 to 1.06) in the 7-day moving average, after adjusting for ozone. There was an 8.5% decrease in risk in the multipollutant model, proportional to a decrease of SO{sub 2} concentrations. The results of this study suggest that residents of medium-sized Brazilian cities with characteristics similar to those of São José dos Campos probably have health problems due to exposure to air pollutants.

    2013-07-31

    This report presents the accomplishments at the completion of the DOE sponsored project (Contract # DE-FC26-09NT05873) undertaken by Solar Turbines Incorporated. The objective of this 54-month project was to develop a low NOx combustion system for a medium sized industrial gas turbine engine operating on Hydrogen-rich renewable and opportunity Fuels. The work in this project was focused on development of a combustion system sized for 15MW Titan 130 gas turbine engine based on design analysis and rig test results. Although detailed engine evaluation of the complete system is required prior to commercial application, those tasks were beyond the scope of this DOE sponsored project. The project tasks were organized in three stages, Stages 2 through 4. In Stage 2 of this project, Solar Turbines Incorporated characterized the low emission capability of current Titan 130 SoLoNOx fuel injector while operating on a matrix of fuel blends with varying Hydrogen concentration. The mapping in this phase was performed on a fuel injector designed for natural gas operation. Favorable test results were obtained in this phase on emissions and operability. However, the resulting fuel supply pressure needed to operate the engine with the lower Wobbe Index opportunity fuels would require additional gas compression, resulting in parasitic load and reduced thermal efficiency. In Stage 3, Solar characterized the pressure loss in the fuel injector and developed modifications to the fuel injection system through detailed network analysis. In this modification, only the fuel delivery flowpath was modified and the air-side of the injector and the premixing passages were not altered. The modified injector was fabricated and tested and verified to produce similar operability and emissions as the Stage 2 results. In parallel, Solar also fabricated a dual fuel capable injector with the same air-side flowpath to improve commercialization potential. This injector was also test verified to produce 15

    Several acoustic models, such as the poro-elastic model, visco-elastic model, and multiple scattering model, have been used for describing the dispersion relation in a porous granular medium. However, these models are based on continuum or scattering theory, and therefore cannot explain the broadband measurements in cases where scattering and non-scattering losses co-exist. Additionally, since the models assume that the porous granular medium consists of grains of identical size (unimodal size distribution), the models does not account for the behavior of wave dispersion in a medium that has a distribution of differing grain sizes. As an alternative approach, this study proposes a new broadband attenuation model that describes the high frequency dispersion relation for the p-wave in the case of elastic grain scatterers existing in the background fluid medium. The broadband model combines the Biot-Stoll plus grain contact squirt and shear flow (BICSQS) model and the quasicrystalline approximation (QCA) multiple scattering model. Additionally, distribution of grain size effect is examined rudimentarily through consideration of bimodal grain size distribution. Through the quantitative analysis of the broadband model and measured data, it is shown that the model can explain the attenuation dependencies of frequency and grain size distribution for a water-saturated granular medium in the frequency range from 350kHz to 1.1MHz. This study can be applied to the high frequency acoustic SONAR modeling and design in the water-saturated environment. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available The issue of the development of small and medium-sized business is relevant for many years. In the article, the questions of the support of small business through the system of public procurement are considered. Within this research, the authors have tried to systematize the data on the dynamics and structure of the public procurements from the point of view of the participation of small business in the purchasing process from the moment of the adoption of the Federal Public Contracts Act that allowed to reveal certain tendencies. The main methods of the research are the vertical and horizontal analysis of time series, the correlation and regression models of the panel data. The data on the participation of small business in the public procurements are grouped by various characteristics depending on the analysis purpose. The groups of the data have been analyzed on 83 entities of the Russian Federation. It has allowed making a full-scale estimation of the efficiency of procurements from the economics point of view. To estimate the influence of procurements on the development of small business entities, three hypotheses have been put forward: an increase in a number of customers placing orders for the small business enterprises, and a decrease in a share of the customers who are not meeting the requirements of the law about the threshold of 15 % lead to the growth of the budget savings; an increase in a number of demands for small business enterprises leads to the increase in the number of these enterprises in the regions; the number of the applications placed for small business entities influences the turnover of small enterprises. On the basis of the panel data of the unified information system of the central and local government procurement for the period of 2011–2015, econometric models confirming the hypotheses have been built. The authors’ calculations may be used by the authorities for the further development of measures for the

    Full Text Available Background: Small and medium-sized enterprises (SMEs, especially in the Western Cape Province of South Africa, are currently facing various financial and other obstacles, which may threaten their survival. Globalisation, the lowering of trade barriers and the reduction of import tariffs have resulted in increased international competition. Businesses are thus forced to undertake continuous improvements and innovation in order to survive, to keep abreast of change and to excel.Objectives: Effective knowledge sharing and consequent knowledge management (KM have been identified as definite approaches to enhancing competitive advantage. The research therefore aimed to establish to what extent small enterprises embrace their knowledge sharing activities and whether their knowledge sharing activities are managed at all. Furthermore, it examined how their knowledge sharing can contribute to their competitive advantage.Method: A case study approach was followed for this research. Selected SMEs from the engineering sector were the subject of the case study and SME owners, directors and managers of consulting civil engineering firms were interviewed to determine whether there are mechanisms in place to ensure better knowledge sharing within SMEs.Results: In general, respondents had stated that they possessed special factors that set them above their competitors:• The company strategy and good reputation of completing projects within the required timeframe. In other words, they were well known for their track record in terms of service delivery. • Their specialty in terms of different focus areas, namely structural and civil engineering, water supply and storm water design, transportation, sewer design and storm water traffic. • The fact that they operated in silos. This means that the specialists in their specific fields operated independently in groups, separately from everyone else in the company. • Their good relationship with local authorities

    Regular physical activity (PA) promotes and excessive sedentary behavior (SB) deteriorates health. Yet the Finnish working-aged population spends most of the day sitting. A 1-year Moving To Business (MTB) -intervention supported small and medium-size workplaces to combat sedentariness. This paper reports the changes in employees' PA and SB from before MTB (baseline) to 1 year after baseline (follow-up). Twelve workplaces with a total of 396 employees participated. Each workplace nominated a team to promote PA and reduce SB at organizational, working unit and employee level. The teams were mentored regionally through meetings, workshop and tools. Changes in PA and SB were assessed with a questionnaire and an accelerometer. Wald Confidence Interval (Cl) for a difference of proportions with matched pairs was used in the questionnaire data (%-points with 95% CI) and linear mixed model in the accelerometer data (minutes and % of wear-time with 95% CI). The mean age of the respondents to the questionnaire (N = 296; 75%) was 42.6 (SD 10.9), 64% were women, 95% had some education after high school, 74% worked in the day shift, 71% did sedentary work and 51% were overweight. The mean number of actions implemented in the workplaces was 6.8 and the multilevel approach was fully applied in 6 workplaces. Based on the questionnaire the time spent in SB decreased from baseline to follow-up 16% (95% CI -29 to -3) in total and 22% (-41 to -3) at work. The accelerometer showed daily increases of 33.7 min (15.3 to 52.1) and 6.8% (3.1 to 10.4) in total PA, 30.9 min (15.3 to 46.5) and 6.1% (2.9 to 9.2) in light PA and 673 (209 to 1139) more steps at work. Daily SB at work decreased 44.9 min (-68.0 to -21.8) and 7.6% (-11.9 to -3.2). Daily leisure PA declined 11.0 min (-24.9 to 2.9) and 3.2% (-6.2 to -0.2). Number of levels or actions had no effect on changes. Employees' PA increased and SB reduced at work during the intervention. At the same time leisure PA decreased slightly

    Full Text Available The purpose of this study was to examine internationalisation barriers of manufacturing SMEs operating in Leather and Leather Products Industry located in the capital city of Ethiopia. The small and medium sized enterprises (SMEs sector in Ethiopia is a significant group within the economy in terms of firm numbers and total employment. However, the SMEs sector’s share of exports is disproportionately small, which raised considerable research concerns. Firm export propensity was the dependent variable and internal and external export barrier factors were used as explanatory variables. The study was conducted through mixed research design of quantitative survey and case study. From the population of manufacturing SMEs operating in the Leather and Leather products Industry, a sample was selected through the use of stratified random sampling to ensure the effective representation of the population of exporting and non-exporting SMEs in the capital of Ethiopia. In order to complement survey results nine (4 exporting and 5 non-exporting SMEs were selected through critical case purposive sampling and an in-depth interviews were conducted. Statistical package for the social sciences (SPSS 20 was used to analyse the quantitative data whereas, qualitative data were analysed manually. Exploratory factor analysis with Varimax rotation and Binary logistic regression analysis are the analytical methods used. The statistical result showed that, logistics problem, insufficient finance, functional barriers, lack of export knowledge and information, procedural barriers and international trade barriers are the most significant obstacles of export trade in Ethiopia. The overall results revealed that explanatory variables used in the analysis significantly predict the dependent variable at 95% confidence level. Taken together, these results prompted the presentation of numerous implications for theory, practice, and future research. Finally, the paper recommended

    Due to increased globalisation, industries are facing greater competition that is pressing companies into decreasing their expenses in order to increase their profits. As regards Swedish industry, it has been faced with substantial increases in energy prices in recent years. Barriers to energy efficiency such as imperfect information inhibit investments in energy efficiency measures, energy audits being one means of reducing barriers and overcoming imperfect information. However, an evaluation of such energy audits in Sweden reveals that it is chiefly low-cost measures that are undertaken as a result of an audit. Moreover, these audits often tend to focus on support processes such as ventilation, lighting, air compressors etc., while measures impacting production processes are often not as extensively covered, which underlines the need for further support in addition to energy audits. Decision support is practised in a variety of different disciplines such as optimization and simulation and the aim of this paper is to explore whether investment decision support practices may be used successfully towards small and medium-sized manufacturers in Sweden when complex production-related investment decisions are taken. The optimization results from the different cases, involving a foundry's investment in a new melting unit, indicate that with no electricity price fluctuations over the day, the investment seems sound as it lowers the overall energy costs. However, with fluctuating electricity prices, there are no large differences in energy costs between the option of retaining the existing five melting furnaces at the foundry and investing in a twin furnace and removing the holding furnaces - which was the initial investment plan for the foundry in the study. It would not have been possible to achieve this outcome without the use of investment decision support such as MIND. One of the main conclusions in this paper is that investment decision support, when strategic

    In April 2010 the Dutch decree on emission limit values (ELVs) on medium-sized combustion installations entered into force. Bems sets ELVs for NOx, SO2, PM and CxHy. In 2013 the Bems legislation was transferred to the Activities Decree (In Dutch: Ab - Activiteitenbesluit). At the same time the Industrial Emissions Directive (IED) was implemented in the Ab. At the time Bems entered into force, it was decided to evaluate this legislation in 2014. Due to incorporation of Bems and the implementation of the IED in the Ab, it was decided to perform this evaluation a year earlier, thereby enabling the consideration of several stakeholders' comments on these implementations. This report presents the main conclusions of this evaluation. In Bems, combustion installations smaller than 50 MWth have to comply with ELVs based on Best Available Technology (BAT). Five possible ELVs have been discussed but not implemented in Bems, due to a lack of knowledge. These ELVs have been included in this evaluation. For gas engines < 2.5 MWth the NOx ELV could be more stringent, namely 140 mg/Nm{sup 3} instead of 340 mg/Nm{sup 3}; all ELVs are set at dry conditions in the flue gas and 3% O2. For biogas engines, introduction of the same ELV might be postponed until a comparable ELV enters into force in 2016 in a Californian region. Both the Californian ELV and this ELV need a gas cleaning technology. For (bio)diesel engines the dust ELV could be more stringent, namely 15 mg PM/Nm{sup 3} instead of 50 mg PM/Nm{sup 3}, while for NOx the ELV can be tightened from 450 mg/Nm{sup 3} to 250 mg/Nm{sup 3}. Both ELVs may be postponed until Tier 4 limits in the USA enter into force in the period 2014-2017. The Netherlands is one of the very few countries with CxHy ELVs for gas engines. The current CxHy ELV of 1500 mg C/Nm{sup 3} may be tightened to 1200 mg C/Nm{sup 3}. Other issues and changes, directly related to the Dutch legislation, have been discussed as well. These include exemption rules

    2017-12-01

    Medium-sized food manufacturing enterprises in Indonesia are significant in a number of contexts, in terms of their part to the national production (GDP) and their establishment to the employment. In term of their role to national production, manufacturing sector contributes the highest GDP by 85%. In this sector, food manufacturing subsector contributes the highest GDP. Nevertheless, they faced the same common problems: quality of human capital and sustainability issues. Previous government supplementary programs have been established to expand the human capital capability amongst medium enterprises. Adequate amount of fund has been apportioned to develop human capital, though, the medium enterprises sustainability is still in question. This study proposes and examines the human capital role from informal knowledge sharing perspective. By conducting qualitative approach through interviews to four informants in Indonesian medium-sized food manufacturing enterprises, a set of hypotheses is derived from this study for future quantitative study. This study indicates that human capital traits (diverse education background, employee skills, and employee experience) could leverage the practice of informal knowledge sharing. Constructs such as mutual trust and reciprocal intention could play as mediating variables, and cultural interpretation perspective could act as moderating factor to informal knowledge sharing effectiveness. In final, informal knowledge sharing is indicated to play as moderating variable for human capital policy and practice to support enterprise sustainability.

Survey data from The National Study of Small and Medium-sized Physician Practices were used. Primary data collection was also conducted to assess community-level PR activities. The final sample included 643 practices engaged in quality reporting; about half of these practices were subject to PR. We used a treatment effects model. The instrumental variables were the community-level variables that capture the level of PR activity in each community in which the practices operate. (1) PR is associated with increased use of CMPs, but the estimate is not statistically significant; (2) financial incentives are associated with greater use of CMPs; (3) practices' awareness/sensitivity to quality reports is positively related to their use of CMPs; and (4) combined PR and financial incentives jointly affect CMP use to a greater degree than either of these factors alone. Small- to medium-sized practices appear to respond to PR and financial incentives by greater use of CMPs. Future research needs to investigate the appropriate mix and type of incentive arrangements and quality reporting. © Health Research and Educational Trust.

    Full Text Available Due to their remarkable resistance to extreme conditions, Deinococcaceae strains are of great interest to biotechnological prospects. However, the physiology of the extremophile strain Deinococcus geothermalis has scarcely been studied and is not well understood. The physiological behaviour was then studied in well-controlled conditions in flask and bioreactor cultures. The growth of D. geothermalis type strains was compared. Among the strains tested, the strain from the German Collection of Microorganisms (Deutsche Sammlung von Mikroorganismen DSM DSM-11302 was found to give the highest biomass concentration and growth rate: in a complex medium with glucose, the growth rate reached 0.75 h−1 at 45 °C. Yeast extract concentration in the medium had significant constitutive and catalytic effects. Furthermore, the results showed that the physiological descriptors were not affected by the inoculum preparation steps. A batch culture of D. geothermalis DSM-11302 on defined medium was carried out: cells grew exponentially with a maximal growth rate of 0.28 h−1 and D. geothermalis DSM-11302 biomass reached 1.4 g·L−1 in 20 h. Then, 1.4 gDryCellWeight of biomass (X was obtained from 5.6 g glucose (Glc consumed as carbon source, corresponding to a yield of 0.3 CmolX·CmolGlc−1; cell specific oxygen uptake and carbon dioxide production rates reached 216 and 226 mmol.CmolX−1·h−1, respectively, and the respiratory quotient (QR value varied from 1.1 to 1.7. This is the first time that kinetic parameters and yields are reported for D. geothermalis DSM-11302 grown on a mineral medium in well-controlled batch culture.

    2009-07-01

    In this study, a complete mass balance of magnetite and coal in the various parts of a dense-medium cyclone (DMC) circuit was determined and fractional size distributions of magnetite and coal were analyzed for the circuit. The DMC overflow product contained 71.34% of the feed coal, whereas 88.35% of the feed magnetite reported to the DMC underflow. The majority of the magnetite (about 86%) was removed by the sieve bends in both the DMC underflow and overflow streams. Sixty-one percent of the raw coal within a size range of 0.50-20.00mm was recovered as clean coal with an average ash content of 15.30%. About 77% of the feed magnetite having a size range of 75-600m was obtained from the underflow of the drain-and-rinse screen belonging to DMC underflow.

    Full Text Available http://dx.doi.org/10.5007/2175-7925.2015v28n3p121 Seasonal forests are one of the most endangered ecosystems in the Atlantic Forest biome, with few protected areas and scarce knowledge on fauna. In order to contribute by means of data on mammal occurrence, distribution, and conservation, this study aimed to provide a list of medium and large-sized mammal species in Fritz Plaumann State Park and in surrounding areas and identify the main threats to mammal species in these locations. Having 741 ha, the park is the only protected area with this ecosystem in the state of Santa Catarina, Brazil. In 2007, 2010, and 2012, samplings were carried out through direct and indirect observation, camera traps, and interviews. Twenty three species were registered, representing 42% of the total number of medium and large-sized land mammals known for the state of Santa Catarina. Six species fell within some threat level in the state or national red list. Even with a small size, this park is one of the largest forest fragments in this region and a refuge for many species within a matrix under intense anthropogenic pressure (e.g. presence of exotic species, hunting. Areas adjacent to the park also show significance for mammal conservation and further strategies must involve, whenever possible, the region as a whole.

  19. Relative impact of on-road vehicular and point-source industrial emissions of air pollutants in a medium-sized Andean city

    2017-03-01

    Cities in emerging countries are facing a fast growth and urbanization; however, the study of air pollutant emissions and its dynamics is scarce, making their populations vulnerable to potential effects of air pollution. This situation is critical in medium-sized urban areas built along the tropical Andean mountains. This work assesses the contribution of on-road vehicular and point-source industrial activities in the medium-sized Andean city of Manizales, Colombia. Annual fluxes of criteria pollutants, NMVOC, and greenhouse gases were estimated. Emissions were dominated by vehicular activity, with more than 90% of total estimated releases for the majority of air pollutants. On-road vehicular emissions for CO (43.4 Gg/yr) and NMVOC (9.6 Gg/yr) were mainly associated with the use of motorcycles (50% and 81% of total CO and NMVOC emissions respectively). Public transit buses were the main source of PM10 (47%) and NOx (48%). The per-capita emission index was significantly higher in Manizales than in other medium-sized cities, especially for NMVOC, CO, NOx and CO2. The unique mountainous terrain of Andean cities suggest that a methodology based on VSP model could give more realistic emission estimates, with additional model components that include slope and acceleration. Food and beverage facilities were the main contributors of point-source industrial emissions for PM10 (63%), SOx (55%) and NOx (45%), whereas scrap metal recycling had high emissions of CO (73%) and NMVOC (47%). Results provide the baseline for ongoing research in atmospheric modeling and urban air quality, in order to improve the understanding of air pollutant fluxes, transport and transformation in the atmosphere. In addition, this emission inventory could be used as a tool to identify areas of public health exposure and provide information for future decision makers.

    The book presents a wealth of information and topical findings compiled in a database, relating to energy consumption by small and medium-sized business in Germany, describing energy consumption patterns in a crosscut survey of business activities characterized by a great technological variety. Based on results obtained from investigations performed in selected enterprises, a questionnaire has been formulated and distributed to almost 3 000 establishments, collecting information on their energy consumption, their installed energy technology, and their activities and equipment for energy conservation. The book presents entirely new information on energy consumption patterns of small and medium-sized business not considered so far by relevant research activities, and gives detailed information and extrapolated results permitting a comparative analysis of particular branches of business, as e.g. the motor vehicle trade, the baker's trade, agriculture, retail trade, hotels, public administration. The latest available survey on energy consumption patterns of small and the medium-sized industry dates back to 1982, and did not consider energy conservation measures or technology.

    Research-intensive small and medium-sized enterprises (SMEs) play a crucial role in the advancement of the biotechnology industry. This paper explored the impacts of internal and contextual variables on innovative activity in Korea and compared the results of this analysis with previous studies of other countries. Our analysis of 149 Korean biotech SMEs showed that the ratio of R&D expenditure to sales, the ratio of R&D employees to total employees, CEO characteristics, governmental support and international networking are positively correlated with a firm's innovation performance. The results may help decision makers to better foster SMEs in the Korean biotechnology industry.

    Although several studies examined the transport of viruses in terrestrial systems only few studies exist on the use of marine phages (i.e., nonterrestrial viruses infecting marine host bacteria) as sensitively detectable microbial tracers for subsurface colloid transport and water flow. Here, we systematically quantified and compared for the first time the effects of size, morphology and physicochemical surface properties of six marine phages and two coliphages (MS2, T4) on transport in sand-filled percolated columns. Phage-sand interactions were described by colloidal filtration theory and the extended Derjaguin-Landau-Verwey-Overbeek approach (XDLVO), respectively. The phages belonged to different families and comprised four phages never used in transport studies (i.e., PSA-HM1, PSA-HP1, PSA-HS2, and H3/49). Phage transport was influenced by size, morphology and hydrophobicity in an approximate order of size > hydrophobicity ≥ morphology. Two phages PSA-HP1, PSA-HS2 (Podoviridae and Siphoviridae) exhibited similar mass recovery as commonly used coliphage MS2 and were 7-fold better transported than known marine phage vB_PSPS-H40/1. Differing properties of the marine phages may be used to trace transport of indigenous viruses, natural colloids or anthropogenic nanomaterials and, hence, contribute to better risk analysis. Our results underpin the potential role of marine phages as microbial tracer for transport of colloidal particles and water flow.

    The study was aimed to compare arthroscopic proximal biceps tenodesis and open subpectoral biceps tenodesis in repair of small or medium rotator cuff tears. Eighty-five patients underwent biceps tenodesis with arthroscopic repair of a rotator cuff tear, and 66 patients were followed for median of 26.8 (18-42) months with ultrasonography were reviewed. The arthroscopic biceps tenodesis group included 34 cases, and the open subpectoral biceps group included 32 cases. Patients were evaluated using visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), and constant scores. Rotator cuff repair and fixation of the biceps tendon were assessed by ultrasonography. Fixation failure and degree of deformity were evaluated by the pain in the bicipital groove and biceps apex distance (BAD). VAS score and tenderness at the bicipital groove decreased significantly in the open subpectoral group at 3 months postoperative. In both groups, the range of motion, ASES score, and constant score increased significantly (P tendinitis and using intra-bicipital groove tenodesis technique. III.

    Full Text Available Fullerenol (C60(OH24 nanoparticles (FNP have a significant role in biomedical research due to their numerous biological activities, some of which are cytoprotective and antioxidative properties. The aim of this study was to measure distribution of fullerenol nanoparticles and zeta potential in cell medium RPMI 1640 with 10% fetal bovine serum (FBS and to investigate the influence of FNP on Chinese hamster ovary cells (CHO-K1 survival, as well as to determine the activity of three antioxidative enzymes: superoxide-dismutase, glutathione-reductase and glutathione-S-transferase in mitomycin C-treated cell line. Our investigation implies that FNP, as a strong antioxidant, influence the cellular redox state and enzyme activities and thus may reduce cell proliferation, which confirms that FNP could be exploited for its use as a cytoprotective agent.[Projekat Ministarstva nauke Republike Srbije, br.

    Full Text Available This paper reports the results of a quantitative analysis examining factors affecting electronic journal usage at the J.N. Desmarais Library of Laurentian University. This study covered an 11-year period, from 2000 to 2010. The number of full-text articles downloaded was compared to the size of the e-journal collection, the number of students, and the number of faculty members at the university, all of which exerted varying degrees of influence on the rate of use of e-journals. Pearson’s Product-Moment Correlation Coefficients were calculated to determine the strength of any existing linear relationship. Although the size of the e-journal collection did impact its level of use, there seems to be a “critical mass” which once reached will slow or stop any further increase in usage. Among the student population, the number of doctoral students demonstrated the strongest linear relationship to the use of the e-journal collection while the undergraduate population showed the least strong linear relationship. Faculty members were important users of the library’s e-journal collection but the linear relationship was not as strong as that observed for graduate students. In fact, faculty members demonstrated the least strong linear relationship of all segments of the Laurentian University community. It may be wise for the library to consult not only its faculty members but also its graduate students when seeking advice on collection building and management.

    The increasing number of nanotechnology products on the market poses increasing human health risks by particle exposures. Adverse effects of silver nanoparticles (AgNPs) in various cell lines have been measured based on exposure dose after a fixed time point, but NP uptake kinetics and the time-dependent internal cellular concentration are often not considered. Even though knowledge about relevant timescales for NP uptake is essential, e.g. for time- and cost-effective risk assessment through modelling, insufficient data are available. Therefore, the authors examined uptake rates for three different AgNP sizes (20, 50 and 75 nm) and two tissue culture medium compositions (with and without foetal calf serum, FCS) under realistic exposure concentrations in pulmonary epithelial 16HBE14o-cells. The quantification of Ag in cells was carried out by high-resolution inductively coupled plasma mass spectrometry. We show for the first time that uptake kinetics of AgNPs into 16HBE14o-cells was highly influenced by medium composition. Uptake into cells was higher in medium without FCS, reaching approximately twice the concentration after 24 h than in medium supplemented with FCS, showing highest uptake for 50-nm AgNPs when expressed on a mass basis. This optimum shifts to 20 nm on a number basis, stressing the importance of the measurand in which results are presented. The importance of our research identifies that not just the uptake after a certain time point should be considered as dose but also the process of uptake (timing) might need to be considered when studying the mechanism of toxicity of nanoparticles.

    Full Text Available The backbone assignment of medium-sized proteins is rarely as straightforward as that of small proteins, and thus often requires creative solutions. Here, we describe the application of a combination of standard 3D heteronuclear methods with CC(CONH and a variety of MUltiplicity Selective In-phase Coherence transfer (MUSIC experiments. Both CC(CONH and MUSIC are, in theory, very powerful methods for the backbone assignment of proteins. Due to low sensitivity, their use has usually been linked to small proteins only. However, we found that combining CC(CONH and MUSIC experiments simplified the assignment of two challenging medium-sized proteins of 13 and 19.5 kDa, respectively. These methods are to some extent complementary to each other: CC(CONH acquired with a long isotropic mixing time can identify amino acids with large aliphatic side chains. Whereas the most sensitive MUSIC experiments identify amino acid types that cannot be detected by CC(CONH, comprising the residues with acid and amide groups, and aromatic rings in their side chains. Together these methods provide a means of identifying the majority of peaks in the 2D 15N HSQC spectrum which simplifies the backbone assignment work even for proteins, e.g., small kinases, whose standard spectra resulted in little spectral resolution and low signal intensities.

    Full Text Available The study attempted to assess the factors that are affecting business performance of small to medium sized family owned businesses in the Zimbabwean retail sector. The objective was to establish the effect of innovation, management skills, succession planning and corporate governance on family owned SMEs in Zimbabwe. The study sought to complement other previous studies that were carried out in other different contexts by producing evidence on the same phenomenon from a developing country context. The study adopted a quantitative approach. A self-administered survey was conducted to collect data that was analysed using descriptive, correlation and regression analyses. The results showed that the most significant factors affecting business performance in order of predictive power were innovation, proper management skills, succession planning and corporate governance. The findings have implications to family business managers and owners in Zimbabwe who are encouraged to be innovative, properly manage, practise succession planning and be guided by business morals in managing their enterprises. Whilst the factors ensuring the success of Small and Medium sized enterprises have extensively been examined, there is dearth of research on family business success factors especially in a developing country like Zimbabwe.

    Full Text Available An air-conditioned coach is an important form of transportation in modern motorized society; as a result, there is an increasing concern of in-vehicle air pollution. In this study, we aimed to identify and quantify the levels of volatile organic compounds (VOCs and carbonyl compounds (CCs in air samples collected from the cabins of newly produced, medium- and large-size coaches. Among the identified VOCs and CCs, toluene, ethylbenzene, xylene, formaldehyde, acetaldehyde, acrolein/acetone, and isovaleraldehyde were relatively abundant in the cabins. Time was found to affect the emissions of the contaminants in the coaches. Except for benzaldehyde, valeraldehyde and benzene, the highest in-vehicle concentrations of VOCs and CCs were observed on the 15th day after coming off the assembly line, and the concentrations exhibited an approximately inverted U-shaped pattern as a function of time. Interestingly, this study also showed that the interior temperature of the coaches significantly affected the VOCs emissions from the interior materials, whereas the levels of CCs were mainly influenced by the relative humidity within the coaches. In China, guidelines and regulations for the in-vehicle air quality assessment of the coaches have not yet been issued. The results of this study provide further understanding of the in-vehicle air quality of air-conditioned coaches and can be used in the development of both specific and general rules regarding medium- and large-size coaches.

    Many serious diseases lack safe and effective vaccines. Using a large commercial database, we examined trends in global vaccine research and development and found that the proportion of new vaccine candidates entering all stages of clinical development increased by 3-5 percentage points over the past two decades. Small and medium-size companies accounted for nearly twice as many new Phase I vaccine trials compared to large companies, but late-stage (Phase III) vaccine trials were dominated by large companies. There were no significant differences between vaccines and drugs in the probability of success in clinical trials or in profitability. Small and medium-size companies, including spin-outs from academic research centers, play an important role in innovative research and discovery. Our findings suggest that policy making targeted at smaller companies, such as prizes or opportunities for public-private partnerships, could support the development of new vaccines, particularly those targeting unmet medical needs and emerging public health threats.

Also, glucoamylase protein concentration is higher in the submerse culture than in the semisolid culture. The other proteins in the submerse culture presented molecular weights lower than 12kDa and in the semisolid culture their molecular weights varied from 21 to 37kDa and below 10kDa.

    Ninety-two daycare centers (23 public, 10 charitable, and 59 private) were identified in the municipality of Pelotas, RS, Southern Brazil. These centers were studied in relation to their organization, services, child-care practices, and infrastructure. All public centers worked full-time, while most private centers operated in the afternoon and received a smaller proportion of children under the age of two. The child-to-attendant ratio was similar in both types of centers, and the nurseries were the classes most frequently above the recommended maximum. Group and center sizes were larger in the public centers. Attendant schooling was higher in the private centers, but task specificity was lower. The infrastructure deficiencies most commonly observed in the public centers were lack of an internal recreational area and playground equipment. Private centers lacked adequate diapering facilities and exclusive toilets for the children. A small proportion of centers had staff trained to handle fire emergencies and administer first aid, revealing insufficient concern over safety issues.

    An examination was made on the slimming possibility and cost reduction of a ready-to-use sealed type lead battery (MF battery) for motorcycles. The MF battery has steadily spread on account of such features as dispensing with water supply and charging. The volumetric efficiency was improved by maximizing the size of the plate group without changing the outside dimension of a battery, thus coping with the slimming need and improvement in production efficiency. Terminal poles with a resin block were positioned away from the notched part of the lid, increasing the height dimension of the plate. The height of the main body of the battery was made the same as before, resulting in the improvement of the plate height by 25%. The volume of the space above the plate in the entire battery volume was reduced by 13%, which increased the volumetric efficiency, enabling the battery to be slimmed. The improvement in the plate height reduced the number of plates per cell, enhancing the production efficiency. Considering interchangeability with the conventional products, the outside shape and capacity were unchanged. The evaluation test revealed that the various characteristics, durability and safety limit were in no way inferior to the conventional products. 9 figs., 1 tab.

    2008-07-01

    Although theory suggests that CEOs who engage in transformational leadership should have a positive effect on firm performance, most empirical examinations using data drawn from larger firms have failed to find support for this linkage. Given that the organizational complexity associated with larger firms has been viewed as a central obstacle to establishing this important link, the authors examined the impact of CEO transformational leadership on firm performance in smaller, privately held firms. After first explaining why the less complex context of these firms provides a setting for transformational CEOs to play a more direct role in enhancing firm performance, they then further clarified the nature of this link by hypothesizing 3 contingencies that they argued are particularly salient: firm size, CEO founder status (founder or nonfounder), and CEO tenure. Results from a multisource survey of CEOs and their top management teams in 121 firms and 2 time-lagged measures of performance, 1 objective and 1 perceived, provided consistent support for these hypotheses.

    To compare the outcomes of shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PNL), and retrograde intrarenal surgery (RIRS) for 10-20 mm radiolucent renal calculi by evaluating stone-free rates and associated complications. A total of 437 patients at 7 institutions who underwent SWL (n = 251), PNL (n = 140), or RIRS (n = 46) were enrolled in our study. Clinical success was defined as stone-free status or asymptomatic insignificant residual fragments PNL, and RIRS (p PNL and RIRS (21.9 vs 5.7 vs 8.7%, respectively; p PNL, and RIRS were 7.6, 22.1, and 10.9%, respectively (p PNL group received blood transfusions, while none of the patients in RIRS and SWL groups transfused. Hospitalization time per patient was 1.3 ± 0.5 days in the RIRS group, while it was 2.6 ± 0.9 days in the PNL group (p PNL group compared to RIRS (145.7 ± 101.7 vs 28.7 ± 18.7 s, and 57.5 ± 22.1 vs 43.1 ± 17 min, respectively). For treatment of moderate-sized radiolucent renal stones, RIRS and PNL provide significantly higher success and lower retreatment rate compared with SWL. Although PNL is effective, its biggest drawback is its invasiveness. Blood loss, radiation exposure, hospital stay, and morbidities of PNL can be significantly reduced with RIRS technique.

    A multi-stage methodology for investigating particulate pollution is developed and implemented for the case study area of Patras, Greece. Initially a low cost particulate matter mass monitor was used to assess aerosol mass concentrations indicating that the city, despite its small size (population around 200,000) and lack of heavy industry, violates both the daily and annual European Union PM standards. Increased PM10 concentrations were observed during the winter but local vehicular traffic was estimated to account for only 12 ± 4% of the PM10 concentration on an annual basis. In the second stage, PM2.5 chemical composition was measured at the urban center and biomass burning was identified as a major PM source during the colder months. In the third stage, PM2.5 concentration and chemical composition was also followed at a mostly upwind rural site around 40 km from the city. The transported pollution was found to account for 50% of the PM2.5 during winter and for more than 70% during the rest of the year. Almost all of the sulfates and 40-90%, depending on the season, of the organic aerosol are transported to the city from other areas. In the last stage, an intensive campaign took place during winter in order to quantify PM sources during the most polluted period. Nighttime sharp increases of the aerosol levels were observed with organic aerosol levels exceeding 80 μg m-3. Local biomass combustion and fossil fuel emissions for domestic heating were responsible for these levels.

    Full Text Available This paper provides key results from an exploratory research study aimed at understanding the current landscape in small- and medium-sized enterprises (SMEs in South Africa with regard to their appetite for, and use of, open innovation. The survey, which was conducted within a contained group of SMEs that belong to business network groups on LinkedIn, explored the current use and perception of open innovation. It was found that collaboration is the approach most preferred by the SMEs surveyed, with customers and suppliers as their preferred innovation partners. Based on the findings of the survey, this paper proposes 25 design requirements, grouped into five functional categories, for an open innovation approach. The design requirements have been developed as a primer to a more complete open innovation approach for SMEs.

    Work-related stress in small and medium-sized enterprises (SMEs) is an increasing problem. However, knowledge regarding organizational-level interventions in SMEs is limited, and SMEs often lack professional facilitator resources to assist in change processes. An intervention program developed...... for large corporations, the PoWRS (Prevention of Work-Related Stress) program, has been modified to fit the conditions in SMEs, i.e., appointing employees as in-house facilitators. The aim of this paper is to examine the enablers and inhibiting factors of the PoWRS program when applied in four Danish SMEs....... Three out of four of the case companies succeeded in implementing the program. The enablers and inhibiting factors related to three themes: persons and roles, program components, and organizational context. Findings show that the primary enabling factors were the in-house employee facilitators...

    Increased interest in using platelet-rich plasma (PRP) as an augment to rotator cuff repair warrants further investigation, particularly in smaller rotator cuff tears. To examine the effectiveness of PRP application in improving perioperative pain and function and promoting healing at 6 months after arthroscopic repair of small- or medium-sized rotator cuff tears. Randomized controlled trial; Level of evidence, 1. This was a double-blinded randomized controlled trial of patients undergoing arthroscopic repair of partial- or full-thickness rotator cuff tears of up to 3 cm who were observed for 6 months. Patients were randomized to either repair and PRP application (study group) or repair only (control group) groups. The patient-oriented outcome measures utilized were the visual analog scale (VAS), the Short Western Ontario Rotator Cuff Index (ShortWORC), the American Shoulder and Elbow Surgeons (ASES) form, and the Constant-Murley Score (CMS). Range of motion (ROM) and inflammatory and coagulation markers were measured before and after surgery. Magnetic resonance imaging was used at 6 months to assess retear and fatty infiltration rate. Eighty-two patients (41 males) with a mean age of 59 ± 8 years were enrolled; 41 patients were included in each group. Both the PRP and control groups showed a significant improvement in their pain level based on the VAS within the first 30 days (P .05), retear (14% vs 18% full retear; P = .44), or fatty infiltration rate (P = .08). The PRP biological augmentation for repair of small- to medium-sized rotator cuff tears has a short-term effect on perioperative pain without any significant impact on patient-oriented outcome measures or structural integrity of the repair compared with control group.

    Despite their importance for water uptake and transport, the xylem anatomical and hydraulic properties of tree roots have only rarely been studied in the field. We measured mean vessel diameter (D), vessel density (VD), relative vessel lumen area (lumen area per xylem area) and derived potential hydraulic conductivity (Kp) in the xylem of 197 fine- to medium-diameter roots (1-10 mm) in the topsoil and subsoil (0-200 cm) of a mature European beech forest on sandy soil for examining the influence of root diameter and soil depth on xylem anatomical and derived hydraulic traits. All anatomical and functional traits showed strong dependence on root diameter and thus root age but no significant relation to soil depth. Averaged over topsoil and deep soil and variable flow path lengths in the roots, D increased linearly with root diameter from ∼50 μm in the smallest diameter class (1-2 mm) to ∼70 μm in 6-7 mm roots (corresponding to a mean root age of ∼12 years), but remained invariant in roots >7 mm. D never exceeded ∼82 μm in the 1-10 mm roots, probably in order to control the risk of frost- or drought-induced cavitation. This pattern was overlain by a high variability in xylem anatomy among similar-sized roots with Kp showing a higher variance component within than between root diameter classes. With 8% of the roots exceeding average Kp in their diameter class by 50-700%, we obtained evidence of the existence of 'high-conductivity roots' indicating functional differentiation among similar-sized roots. We conclude that the hydraulic properties of small to medium diameter roots of beech are mainly determined by root age, rendering root diameter a suitable predictor of hydraulic functioning, while soil depth - without referring to path length - had a negligible effect.

    The purpose of the study is to determine whether continued stimulation of mature follicles to allow "catch up" growth of medium-sized follicles in assisted reproductive technology compromises the clinical pregnancy (CPR) and live birth (LBR) rates in IVF/ICSI cycles. This retrospective cohort study reviewed 200 first IVF ± ICSI cycles out of a total of 340 cycles with complete data. Women underwent stimulation protocols with gonadotropins (Gn) and GnRH antagonist. Treatment cycles were divided into two groups (Gp): hCG administration delayed despite the presence of two mature follicles, defined as ≥ 18 mm [Gp1, n = 79] and hCG administration given when there were two mature follicles [Gp2, n = 121]. The patients in Gp1 were significantly younger than those in Gp2 [32.9 (4.5) vs. 34.3 (4.8), p = 0.04] and needed a median of one more day of superovulation before ovulation was triggered with hCG. The extra days was associated with the use of 450 [75-2025] more Gn, such that at the time the hCG was administered, patient's in group 1 had developed significantly greater number of follicles ≥ 18 mm [mean (SD), 4.9 (1.8) vs. 3.4 (1.7), p hCG administration to allow further growth of the medium-sized follicles added further days of superovulation and cost without improvement in CPR and LBR.

    The efficiency of aeration systems should be monitored to guarantee suitable biological processes. Among the available tools for evaluating the aeration efficiency, the off-gas method is one of the most useful. Increasing interest towards reducing greenhouse gas (GHG) emissions from biological processes has resulted in researchers using this method to quantify N2O and CO2 concentrations in the off-gas. Experimental measurements of direct GHG emissions from aerobic digesters (AeDs) are not available in literature yet. In this study, the floating hood technique was used for the first time to monitor AeDs. The floating hood technique was used to evaluate oxygen transfer rates in an activated sludge (AS) tank of a medium-sized municipal wastewater treatment plant located in Italy. Very low values of oxygen transfer efficiency were found, confirming that small-to-medium-sized plants are often scarcely monitored and wrongly managed. Average CO2 and N2O emissions from the AS tank were 0.14 kgCO2/kgbCOD and 0.007 kgCO2,eq/kgbCOD, respectively. For an AeD, 3 × 10-10 kgCO2/kgbCOD direct CO2 emissions were measured, while CO2,eq emissions from N2O were 4 × 10-9 kgCO2,eq/kgbCOD. The results for the AS tank and the AeD were used to estimate the net carbon and energy footprint of the entire plant.

    Full Text Available Background: Information technology has assisted in globalisation, which then assisted in making international trade easier. Consequently, businesses no longer compete with local competitors only but also with international ones, leading to intense competition in all business sectors. Businesses will hardly practice what they are not aware of and therefore needs to know about their competitive landscape. Competitive intelligence (CI gathers information from both the internal and external business environments, and analyses these for use by decision makers. Whilst awareness of the importance of CI is wide, it is not practiced optimally, making the need for creating awareness of the benefits of CI important.Objectives: The objective of this research was to establish the influence of owners’ and managers' working experience of CI practice and awareness in the small and medium-sized enterprises (SMEs environment.Method: This research was quantitative in nature and a questionnaire was used to collect data from SMEs owners and managers in The City of Tshwane Metropolitan Municipality.Results: This research indicates that SMEs in the study are aware of CI through education and training. Moreover, the study reveals that the working experience of owners and managers has a great influence on awareness and practice of CI and one should implement training programmes in this domain to assist with building competitive advantage.Conclusion: Small and medium-sized enterprises owners or managers’ years of working experience has a greater influence on awareness and practice of CI. Put differently, years of working experience is a great predictor of CI awareness and practice.

    An abdominal advancement flap (AAF) is a flap that pulls the elevated abdominal skin up, creating the shape of the inferior portion of the breast by making a neo-inframammary fold. We used an AAF combined with volume displacement techniques to fill the defect left after breast-conserving surgery (BCS). Forty-one small- to medium-sized breast patients whose resection area included the lower portion of the breast underwent this procedure from October 2010 to December 2014. We evaluated efficacy of this procedure. The excision volume ranged from 10 to 35 %. Complications after surgery were observed in two patients (partial necrosis of the nipple-areola complex and partial necrosis of the breast skin in one patient each). There was no fat necrosis of the flap in any of the patients. The cosmetic results were found to be excellent in 7 cases, good in 23, fair in 9 and poor in 2. In 11 cases with an unacceptable outcome, 9 cases were in the inner portion. In patients with the tumor in the inner portion, the proportion of unacceptable cases was 50 %. In the cases other than the inner portion, the proportion of unacceptable cases was 8.7 % (p < 0.01). In the cases with larger breasts, unacceptable cases were more frequently observed (p < 0.05). We believe that an AAF combined with volume displacement techniques may be useful following BCS in the lower portion of a small- to medium-sized breast, except in cases where the tumors is located in the inner potion.

    Full Text Available The Greater Addo Elephant National Park project (GAENP involves the establishment of a mega biodiversity reserve in the Eastern Cape, South Africa. Conservation planning in the GAENP planning domain requires systematic information on the potential distributions and estimated spatial requirements, and population sizes of the medium to largesized mammals. The potential distribution of each species is based on a combination of literature survey, a review of their ecological requirements, and consultation with conservation scientists and managers. Spatial requirements were estimated within 21 Mammal Habitat Classes derived from 43 Land Classes delineated by expert-based vegetation and river mapping procedures. These estimates were derived from spreadsheet models based on forage availability estimates and the metabolic requirements of the respective mammal species, and that incorporate modifications of the agriculture-based Large Stock Unit approach. The potential population size of each species was calculated by multiplying its density estimate with the area of suitable habitat. Population sizes were calculated for pristine, or near pristine, habitats alone, and then for these habitats together with potentially restorable habitats for two park planning domain scenarios. These data will enable (a the measurement of the effectiveness of the GAENP in achieving predetermined demographic, genetic and evolutionary targets for mammals that can potentially occur in selected park sizes and configurations, (b decisions regarding acquisition of additional land to achieve these targets to be informed, (c the identification of species for which targets can only be met through metapopulation management,(d park managers to be guided regarding the re-introduction of appropriate species, and (e the application of realistic stocking rates. Where possible, the model predictions were tested by comparison with empirical data, which in general corroborated the

    Small- and medium-sized enterprises (SMEs) generate nearly 80% of the jobs in China, but the dangerous work environment often found in these enterprises poses a major concern for public health. Psychosocial pressure and mental health problems among the workers are also common in SMEs. However, mental health of workers in SMEs is largely neglected in occupational health research and practice in China. The purpose of this study is to assess mental health of the workers and to explore the associations between physical and psychosocial work environment and workers' mental health in SMEs in South China. Data were collected in 2012 through a cross-sectional survey among 1200 workers working in small- and medium-sized enterprises (SMEs) in Guangdong, China. Mental health was measured by psychological well-being in the current study. Job Demand-Control-Support (JDCS) model was used as a theoretical framework to examine the psychosocial factors associated with workers' psychological well-being. Data were analyzed using SPSS 20.0 and analysis was performed using bivariate analyses and multivariate logistic regression. About three in ten workers (35.3%) in the sample had poor psychological well-being. Those who were men, younger in age, or migrant workers had worse psychological outcome in bivariate analyses. After controlling for individual variables (gender, age, marital status, and household registration), we found that longer weekly work hours (OR = 1.30, 95% CI: 1.13 ~ 1.50), more exposure to hazardous work environment (OR = 1.26, 95% CI: 1.10 ~ 1.44), higher job demands (OR = 1.29, 95% CI: 1.12 ~ 1.49), and lower job autonomy (OR = 0.70, 95% CI: 0.60 ~ 0.81) were significant associated with worse psychological well-being. The results were consistent with predictions of the JDCS model. The results indicate that the JDCS model is a useful framework in predicting psychological well-being among Chinese workers in SMEs. Future mental health promotion should focus on young

    This paper presents a survey of the experiments on runaway electrons (RE) carried out recently in frames of EUROFusion Consortium in different tokamaks: COMPASS, ASDEX-Upgrade, TCV and JET. Massive gas injection (MGI) has been used in different scenarios for RE generation in small and medium-sized tokamaks to elaborate the most efficient and reliable ones for future RE experiments. New data on RE generated at disruptions in COMPASS and ASDEX-Upgrade was collected and added to the JET database. Different accessible parameters of disruptions, such as current quench rate, conversion rate of plasma current into runaways, etc have been analysed for each tokamak and compared to JET data. It was shown, that tokamaks with larger geometrical sizes provide the wider limits for spatial and temporal variation of plasma parameters during disruptions, thus extending the parameter space for RE generation. The second part of experiments was dedicated to study of RE generation in stationary discharges in COMPASS, TCV and JET. Injection of Ne/Ar have been used to mock-up the JET MGI runaway suppression experiments. Secondary RE avalanching was identified and quantified for the first time in the TCV tokamak in RE generating discharges after massive Ne injection. Simulations of the primary RE generation and secondary avalanching dynamics in stationary discharges has demonstrated that RE current fraction created via avalanching could achieve up to 70–75% of the total plasma current in TCV. Relaxations which are reminiscent the phenomena associated to the kinetic instability driven by RE have been detected in RE discharges in TCV. Macroscopic parameters of RE dominating discharges in TCV before and after onset of the instability fit well to the empirical instability criterion, which was established in the early tokamaks and examined by results of recent numerical simulations.

    The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high energy -ray observatory. CTA will consist of two arrays: one in the Northern hemisphere composed of about 20 telescopes, and the other one in the Southern hemisphere composed of about 100 telescopes, both arrays containing telescopes of different sizes and types and in addition numerous auxiliary devices. In order to provide a test-ground for the CTA array control, the steering software of the 12-m medium size telescope (MST) prototype deployed in Berlin has been implemented using the tools and design concepts under consideration to be used for the control of the CTA array. The prototype control system is implemented based on the Atacama Large Millimeter/submillimeter Array (ALMA) Common Software (ACS) control middleware, with components implemented in Java, C++ and Python. The interfacing to the hardware is standardized via the Object Linking and Embedding for Process Control Unified Architecture (OPC UA). In order to access the OPC UA servers from the ACS framework in a common way, a library has been developed that allows to tie the OPC UA server nodes, methods and events to the equivalents in ACS components. The front-end of the archive system is able to identify the deployed components and to perform the sampling of the monitoring points of each component following time and value change triggers according to the selected configurations. The back-end of the archive system of the prototype is composed by two different databases: MySQL and MongoDB. MySQL has been selected as storage of the system configurations, while MongoDB is used to have an efficient storage of device monitoring data, CCD images, logging and alarm information. In this contribution, the details and conclusions on the implementation of the control software of the MST prototype are presented.

    The subjects of this study were 405 Japan Medical Association authorized industrial physicians, Community Industrial Physicians (CIPs), who belonged to the Shinjuku, Nakano, and Suginami Words' regional medical associations in the jurisdiction of the Shinjuku Labor Standards Inspection Office. Between November and December, 2003, the CIPs were mailed a questionnaire requesting information about their affiliations and activities, and as indicators of their willingness to participate in Community Occupational Health Services, they were asked about the pros and cons of having their names published as Industrial Physicians, and/or practitioners for Regional Occupational Health Centers, or Regular Health Checks. 152 replies were received, effective response rate of 37.5%, and among these 94 replies were from CIPs who work as part-time industrial physician. Overall, CIPs attend Community Occupational Health Services (COHS) voluntarily, and wish to participate in them more in the future. CIPs who work as part-time industrial physician have knowledge of working safety and hygiene and are providing advice and guidance on working conditions and environments. Also, they are well informed about support services for small and medium-sized enterprises which is thought to be connected with their willingness to participate in COHS. Furthermore, it is important that part-time CIPs activities are appreciated by their respective place of work.

    The purpose of this particular study was to test a newly created instrument in describing the facilitators and barriers to occupational health and safety in small and medium-sized enterprises (SMEs) in Ontario, Canada. A cross-sectional design was used to identify the occupational health and safety culture of SMEs in public and private sectors in Ontario. A total of 153 questionnaires were completed. The majority of respondents were female (84%) with a mean age of 49.8 years (SD 10.6). Seventy-four percent were supervisors. Seventy percent of respondents were from the private sector while 30% derived from the public sector including healthcare, community services, and non-profit organizations. Further, conducting regular external safety inspections of the workplace was found to be statistically associated with a safe work environment 2.88 95% CI [1.57, 5.27]. Strategies and training opportunities that focus on how to adapt occupational health and safety legislation to the nature and diversity of SMEs are recommended. Furthermore, employers may use such information to improve safety in their SMEs, while researchers can hopefully use such evidence to develop interventions that are applicable to meeting the occupational health and safety needs of SMEs.

    Intimate partner violence (IPV) is a major public health problem, but few evidence-based prevention programs have yet been implemented. This study explored the perceptions and beliefs of local-level decision makers, social and health-care professionals, and representatives from the police force regarding the possibilities and hindrances for prevention of IPV. An explorative qualitative approach was used, and participants were strategically selected for focus group discussions. The participants, 19 men and 23 women, were professionals or decision makers within health-care services, social welfare, municipal administration, the police force, local industry, and local politicians in a Swedish town of 54,000 inhabitants. The focus group discussions were audio recorded, transcribed verbatim, and thematically analyzed. A manifest content analysis was performed on the text. Preschools, schools, sports associations, workplaces, and the mass media were suggested as possible arenas for prevention measures. The proposed activities included norm building and improved social support structures. Hindrances were conceptualized as societal beliefs and attitudes, shame, silence, gender inequality, the counteracting influence of the media, and lack of resources. The participants demonstrated closeness and distance to IPV, expressed as acceptance or referral of responsibility to others regarding where and by whom prevention measures should be executed. This study gave new insights in the prevailing perceptions of professionals and decision makers of a medium-sized Swedish town, which can be a useful knowledge in future preventive work and contribute to bridge the gap between research and practice.

    Full Text Available The objective of this study was to assess the determinants of the readiness of the senior generation owner-managers to finally transfer the management and control of the family business to the younger generation. Data from 504 questionnaires linked to 81 family businesses were collected and analysed. An Oblimin oblique rotation was carried out on the principal components of the exploratory factor analysis. Five factors with eigen-values greater than one, explaining 62.64 per cent of the variance, were extracted. These five factors describing the theoretical dimensions of the dependent variable were: the senior generation owner-manager’s readiness to let go, and the independent variables of retirement planning, perceived suitability of the successor, estate planning, and the perceived liquidity of the business after the transfer. No significant practical differences relating to these five factors could be found between the perceptions of male and female respondents, the senior and younger generation family members or family members involved in medium-sized or small businesses. Practical recommendations are suggested to ensure a smooth final transfer of the management and control of the business to the younger generation family members.

    Many municipal wastewater treatment plants are retrofitted with membrane filtration that replaces secondary clarification. Such a solution saves space and improves overall treatment efficiency but at the cost of increased energy consumption and reduced potential for energy recovery from sewage sludge. Thus, the plant takes a step back from reaching energy self-sufficiency. In the presented case study, two alternative upgrade options were simulated for a medium-size municipal wastewater treatment plant in Poland: the first one assumed optimization of the existing bioreactor, and the other - installation of microfiltration membrane units inside the bioreactor. In both cases, anaerobic digestion of waste sludge with biogas utilization is planned. The results have shown that while under both upgrade options, the plant's capacity can be effectively increased by approximately 50%, their effects on the plant's energy balance will be very different. Although the installation of membrane modules accompanied by the construction of anaerobic digestion tanks improves the plant's energy balance, it will remain negative. The option of optimizing the existing biological treatment system produces a positive energy balance with more energy produced from biogas than consumed. Thus, the plant is able to approach energy self-sufficiency. It has been concluded that retrofitting the plants with membrane filtration is not always the best option from the energy balance point of view and it should be preceded with a detailed analysis on a case-by-case basis.

Data was obtained from the Department of Information and Computing of the Brazilian Unified Health System. Air pollutant data (PM10, SO2, and O3 and daily averages of their concentrations were obtained from the Environmental Sanitation & Technology Company. Statistical analysis was performed by linear and logistic regressions using the Excel and STATA v.7 software programs.RESULTS: Maternal exposure to air pollutants was not associated with low birth weight, with the exception of exposure to SO2 within the last month of pregnancy (OR=1.25; 95% CI=1.00-1.56. Maternal exposure to PM10 and SO2 during the last month of pregnancy led to lower weight at birth (0.28g and 3.15g, respectively for each 1mg/m3 increase in the concentration of these pollutants, but without statistical significance.CONCLUSIONS: This study failed to identify a statistically significant association between the levels of air pollutants and birth weight, with the exception of exposure to SO2 within the last month of pregnancy.

    Urban agriculture is common across Africa and contributes to the livelihoods of urban dwellers. Some crop systems create suitable mosquito breeding sites and thus might affect malaria transmission. The purpose of this study was to identify, map, and characterize potential mosquito breeding sites in agricultural land use zones in a medium-sized town of western Côte d'Ivoire and to assess risk factors for productive Anopheles breeding sites. Two surveys were carried out; one toward the end of the rainy season and the second one during the dry season. In all identified potential mosquito breeding sites, two experienced entomologists searched for the presence of Anopheles larvae and pupae with a standardized technique. Totals of 369 and 589 sites were found in the rainy and dry seasons, respectively, mainly in vegetable gardens and irrigated rice fields. Anopheles larvae were present in 50.7% and 42.4% of the sites investigated during the rainy and dry seasons, respectively. Typical Anopheles larval habitats were characterized by the presence of algae, the absence of floating vegetation, and the co-occurrence of Culex larvae. The highest Anopheles larval productivity was observed in rice paddies, agricultural trenches between vegetable patches, and irrigation wells. An indirect link could be established between the occurrence of productive Anopheles breeding sites and agricultural land use through specific man-made habitats, in particular agricultural trenches, irrigation wells, and rice paddies. Our findings have important bearings for the epidemiology and control of urban malaria in sub-Saharan Africa.

    Ambient concentrations of volatile organic compounds (VOC) and nitrogen dioxide (NO{sub 2}) were measured by means of passive sampling at 40 sampling points in a medium-size city in Northern Spain, from June 2006 to June 2007. VOC and NO{sub 2} samplers were analysed by thermal desorption followed by gas chromatography/mass-selective detector and by visible spectrophotometry, respectively. Mean concentrations of benzene, toluene, ethylbenzene, xylenes, propylbenzene, trimethylbenzenes, and NO{sub 2} were 2.84, 13.26, 2.15, 6.01, 0.59, 1.32 and 23.17 {mu}g m{sup -3} respectively, and found to be highly correlated. Their spatial distribution showed high differences in small distances and pointed to traffic as the main emission source of these compounds. The lowest levels of VOC and NO{sub 2} occurred during summer, owing to the increase in solar radiation and to lower traffic densities. Mean concentrations of benzene and NO{sub 2} exceeded the European limits at some of the monitored points.

    Data and time requirements and complex methodological problems of a detailed Life Cycle Assessment (LCA) are well-known and discussed. Its application has specific difficulties in Italian Small- and Medium- sized Enterprises (SMEs) where environmental information is generally dispersed, a short-term problem-oriented environmental management approach is common and dedicated human resources are usually missing. As a consequence, a new procedure specifically designed for SMEs, VerdEE (Verifica dell'Eco-Efficienza - Verification of Eco-Efficiency), was developed and implemented on an interactive CD-ROM. It is based on the following criteria: relying on a life cycle approach; aimed at evaluating the environmental profile of a product and at identifying improvement opportunities; sufficiently simple to be applied in a limited time; containing as much quantitative information as possible to make it usable by a non-expert user. The VerdEE procedure includes four main steps: "Goal and Scope definition" semi-quantitative "Inventory" "Check-list" visualisation of results in "Matrix" and "Target-plot" form. The procedure is supported by an interconnected informative part about advantages of the life cycle approach for SMEs, principles of eco-design and environmental concerns.

    Usually an underground mining company designs new production systems in order to reach higher productivity levels, but there is always some uncertainty about reaching the planned figures. This research project, so called Project SimCAR, applies to medium or small sized coal mining companies and tries to become a powerful tool in helping technical staff to answer questions about how future systems will behave. The project`s paradigm is to use computer simulation techniques in order to diminish the implicit uncertainty associated to coal mining activities. As a result, this implies to obtain the best possible scenarios for real economic investments in mine planning. The final programs we have built help technical staff to: 1. Study existing systems in depth. The precision of the resulting model exclusively depends on the correctness of input data and a perfect understanding of the system`s logic processes. 2. Perform several changes on the input system variables over the simulated models in order to allow the technical staff to know the system will react under several conditions. 3. Introduce new strategies on the model construction in order to get a complete optimization under productive and economic viewpoints. (Author)

    This study analyses the effect of workplace health promotion on work ability and health-related quality of life in white-collar and blue-collar workers in a medium-sized business. The intervention group contains 75 subjects with a mean age of 36.6±10.63 years (55 men, 20 women). The participation rate is 47%. White-collar workers show improvement in their health-related quality of life regarding physical and psychological aspects and work ability. Physically inactive employees show improvement in their health-related quality of life regarding physical and psychological aspects as well as context. Active employees only show significant improvement in terms of work ability. In conclusion, the promotion of exercise in the context of occupational health promotion has a positive effect on quality of life and work ability of employees and, thus, is a benefit for both the individual as well as the business itself. © Georg Thieme Verlag KG Stuttgart · New York.

    Providing unobserved opioid substitution treatment (OST) safely is a major challenge. This study examined whether electronic medicine dispensers (EMDs) can reduce diversion of take-home buprenorphine-naloxone (BNX) in a medium-sized Finnish city. All BNX treated OST patients in Kuopio received their take-home BNX in EMDs for 4months. EMDs' effect on diversion was investigated using questionnaires completed by patients (n=37) and treatment staff (n=19), by survey at the local needle exchange service and by systematic review of drug screen data from the Kuopio University Hospital. The majority of patients (n=21, 68%) and treatment staff (n=11, 58%) preferred to use EMDs for the safe storage of tablets. Five patients (16%) declared that EMDs had prevented them from diverting BNX. However, EMDs had no detectable effect on the availability or origin of illegal BNX or on the hospital-treated buprenorphine-related health problems. EMDs may improve the safety of storage of take-home BNX, but their ability to prevent diversion needs further research. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available There is a paucity of cost-effectiveness studies in India comparing PCNL and ESWL in the treatment of renal cal-culi. We are dependent on costing studies from western literature, although the nature of expenses in developed countries is quite different from those in India. This study compares the two procedures with regards to cost-effec-tiveness & efficacy in clearing medium-sized renal calculi (2.0 cms at our institute. All costs borne by the patient & the institute were taken into account, including equip-ment costs, stay charges & cost of travel incurred, for re-peat visits to the institute. The groups compared had similar stone characteristics & were from our early experience with the two methods. All costing was done at 1998 rates by submitting case sheets to a fresh billing. PCNL, was significantly more efficient at clearing calculi (94% vs 69% than ESWL, but patients needed hospitalization. The re-quirement of ancillary procedures was significantly less with PCNL than ESWL (1 vs 35 and ESWL was more expensive although the difference was not statistically sig-nificant. High initial cost of a lithotripter along with the need for repeated visits to the hospital for clearance of the calculus contribute to the increased cost of ESWL. PCNL ensures clearance of calculi at a single hospital admission with minimal morbidity.

    Full Text Available Abstract The wildlife of the Brazilian Pampa is threatened by large-scale habitat loss, due in particular to the expansion of soybean cultivation and the conversion of grasslands areas into extensive areas of silviculture. It is essential to study how the mammal fauna copes with the highly fragmented, human-influenced, non-protected landscape. Our study presents the results of a survey of the large- and medium-sized mammals of a typical human-influenced steppic savanna area of the Pampa biome. The survey was conducted exclusively with the use of camera traps over a period of 16 months. The relative frequencies of species in the area were evaluated. We recorded 18 species, some of them locally threatened (Tamandua tetradactyla, Alouatta caraya, Leopardus colocolo, Leopardus geoffroyi, Leopardus wiedii, Puma yagouaroundi, Mazama gouazoubira and Cuniculus paca. Several species were found to thrive in the area; however, many species were considered rare, and undoubtedly new species could be recorded if we continued the sampling. Our results contribute to the knowledge of faunal diversity in the Pampa biome and associated habitats, warn about threats and provide support for conservation measures.

    This paper reports the results from an exploratory study that sets out to identify and compare the strategic approaches and patterns of business practice employed by 14 UK small- and medium-sized enterprises to achieve success in the medical device sector of the health-care industry. An interview-based survey was used to construct individual case studies of the medical device technology (MDT) companies. A cross-case analysis was performed to search for patterns and themes that cut across these individual cases. Exploratory results revealed the heterogeneity of MDT companies and the distinctive features of the MDT innovation process that emphasize the importance of a strategic approach for achieving milestones in the product development and exploitation process and for creating value for the company and its stakeholders. Recognizing the heterogeneity of MDT companies, these exploratory findings call for further investigation to understand better the influence of components of the MDT innovation process on the commercialization life cycle and value trajectory. This is required to assist start-up or spin-out MDT companies in the UK and worldwide to navigate the critical transitions that determine access to financial and consumer markets and enhance the potential to build a successful business. This will be important not only for bioscience-based companies but also for engineering-based companies aiming to convert their activities into medical devices and the health- and social-care market.

Samples were collected between February 1999 and January 2000 from lichens and mosses growing on sidewalk trees of the urban and periurban area. Five species of tardigrades were found, i.e., Echiniscus rufoviridis du Bois-Reymond Marcus, 1944, Macrobiotus areolatus Murray, 1907, Ramazzottius oberhaeuseri (Doyère, 1840, Milnesium cf. tardigradum and a non-described species of Macrobiotus. Only one species, M. cf. tardigradum, was found in areas with high levels of vehicle traffic. Results are compared with those from cities in the Nearctic and Palearctic regions. Measurements and pt index values (percentage ratios between the length of the structure considered and the buccal tube length are provided for M. areolatus, R. oberhaeuseri and M. cf. tardigradum. Amongst the characters considered, the pt index for the stylet support insertion shows the least intraspecific variation. This character is also independent from body length and buccal-tube length.

    Full Text Available OBJECTIVES: To explore the relationship between health-related quality of life (HRQOL status and associated factors among rural-to-urban migrants in China. METHODS: A cross-sectional survey was conducted with 856 rural-to-urban migrants working at small- and medium-size enterprises (SMEs in Shenzhen and Zhongshan City in 2012. Andersen's behavioral model was used as a theoretical framework to exam the relationships among factors affecting HRQOL. Analysis was performed using structural equation modeling (SEM. RESULTS: Workers with statutory working hours, higher wages and less migrant experience had higher HRQOL scores. Need (contracting a disease in the past two weeks and perception of needing health service had the greatest total effect on HRQOL (β = -0.78, followed by enabling (labor contract, insurance purchase, income, physical examination during work and training (β = 0.40, predisposing (age, family separation, education (β = 0.22 and health practices and use of health service (physical exercise weekly, health check-up and use of protective equipments (β = -0.20. CONCLUSIONS: Priority should be given to satisfy the needs of migrant workers, and improve the enabling resources.

    The primary purpose of this study was to assess the role, status and scope of workplace HIV/AIDS committees as a means of effective workplace governance of the HIV/AIDS impact, and their role in extending social protective HIV/AIDS-related rights to employees. In-depth qualitative case studies were conducted in five South African small and medium-sized enterprises (SMEs) that were actively implementing HIV/AIDS policies and programmes. Companies commonly implemented HIV/AIDS policies and programmes through a workplace committee dedicated to HIV/AIDS or a generic committee dealing with issues other than HIV/ AIDS. Management, through the human resources department and the occupational health practitioner often drove initial policy formulation, and had virtually sole control of the HIV/AIDS budget. Employee members of committees were mostly volunteers, and were often production or blue collar employees, while there was a notable lack of participation by white-collar employees, line management and trade unions. While the powers of workplace committees were largely consultative, employee committee members often managed in an indirect manner to secure and extend social protective rights on HIV/AIDS to employees, and monitor their effective implementation in practice. In the interim, workplace committees represented one of the best means to facilitate more effective workplace HIV/AIDS governance. However, the increased demands on collective bargaining as a result of an anticipated rises in AIDS-related morbidity and mortality might prove to be beyond the scope of such voluntary committees in the longer term.

  1. Influence of large wood on channel hydraulics, sediment (dis-)connectivity and channel morphology in a medium-sized mixed-load Austrian stream

    It is widely known that large wood (LW) in rivers alters channel hydraulics, channel morphology and sediment transport. Channel spanning LW can create blocking barriers, steps and dams which store sediment and organic material in small reservoirs for the lifetime of the damming structure. Otherwise, the breach of LW key logs and jams makes the long term stored sediment available for fluvial transport. However, detailed field measurements on the distribution of LW and its influence on hydraulic variables, channel morphology and (especially) sediment connectivity are still rare, thus further constituting the major aim of this study. The study was performed along the lower reaches ( 6 km) of the Fugnitz River, a mixed-load, medium-sized (catchment area 130 km2) single-thread perennial stream, located in the Bohemian Massif, Austria. The spatial distribution and characterization of LW (>1 m in length and >10 cm in diameter) was examined along the main stem via field mapping and dGPS measurements. Hydraulic channel parameters (e.g. channel gradient, cross-sectional profiles) and volumes of retained sediment were determined via field measurements, while channel morphology incl. indications of LW-induced geomorphic processes (e.g. bank undercutting, scouring) was obtained via geomorphic mapping. Flow characteristics and bed load transport rates were measured using an Ott-Nautilus and a portable Helley-Smith bed load sampler during different water stages. Additionally, bed sediment textures were examined by performing pebble count analyses. In-channel LW accumulations (total volume of 588 m3) were primarily observed in meandering river reaches as well as in reaches with steep hillslopes. 36% of all LW accumulations were classified as dams, steps or deflectors altering flow conditions or creating backwater areas decreasing sediment connectivity. Highest volumes of sediment storage (total volume of 26 m3) have been primarily recorded at locations where bank erosion processes

    Full Text Available Satellite precipitation products (SPPs are critical data sources for hydrological prediction and extreme event monitoring, especially for ungauged basins. This study conducted a comprehensive hydrological evaluation of six mainstream SPPs (i.e., TMPA 3B42RT, CMORPH-RT, PERSIANN-RT, TMPA 3B42V7, CMORPH-CRT, and PERSIANN-CDR over humid Xixian basin in central eastern China for a period of 14 years (2000–2013. The evaluation specifically focused on the performance of the six SSPs in capturing precipitation and streamflow extremes. Results show that the two post-real-time research products of TMPA 3B42V7 and CMORPH-CRT exhibit much better performance than that of their corresponding real-time SPPs for precipitation estimation at daily and monthly time scales. By contrast, the newly released post-real-time research product PERSIANN-CDR insignificantly improves precipitation estimates compared with the real-time PERSIANN-RT does at daily time scale. The daily streamflow simulation of TMPA 3B42V7 fits best with the observed streamflow series among those of the six SPPs. The three month-to-month gauge-adjusted post-real-time research products can simulate acceptable monthly runoff series. TMPA 3B42V7 and CMORPH-CRT present good performance in capturing precipitation and streamflow extremes, although they still exhibit non-ignorable deviation and occurrence time inconsistency problems compared with gauge-based results. Caution should be observed when using the current TMPA, CMORPH, and PERSIANN products for monitoring and predicting extreme precipitation and flood at such medium-sized basin. This work will be valuable for the utilization of SPPs in extreme precipitation monitoring, streamflow forecasting, and water resource management in other regions with similar climate and topography characteristics.

    In the event of a wide area release and contamination of a biological agent in an outdoor environment and to building exteriors, decontamination is likely to consume the Nation’s remediation capacity, requiring years to cleanup, and leading to incalculable economic losses. This is in part due to scant body of efficacy data on surface areas larger than those studied in a typical laboratory (5×10-cm), resulting in low confidence for operational considerations in sampling and quantitative measurements of prospective technologies recruited in effective cleanup and restoration response. In addition to well-documented fumigation-based cleanup efforts, agencies responsible for mitigation of contaminated sites are exploring alternative methods for decontamination including combinations of disposal of contaminated items, source reduction by vacuuming, mechanical scrubbing, and low-technology alternatives such as pH-adjusted bleach pressure wash. If proven effective, a pressure wash-based removal of Bacillus anthracis spores from building surfaces with readily available equipment will significantly increase the readiness of Federal agencies to meet the daunting challenge of restoration and cleanup effort following a wide-area biological release. In this inter-agency study, the efficacy of commercial-of-the-shelf sporicidal disinfectants applied using backpack sprayers was evaluated in decontamination of spores on the surfaces of medium-sized (∼1.2 m2) panels of steel, pressure-treated (PT) lumber, and brick veneer. Of the three disinfectants, pH-amended bleach, Peridox, and CASCAD evaluated; CASCAD was found to be the most effective in decontamination of spores from all three panel surface types. PMID:24940605

    Full Text Available Orientation: Embracement of triple bottom line reporting as a driver of a firm’s sustainability is a paradox puzzling most contemporary business executives.Research purpose: The purpose of this research is to examine how effective alignment of the triple bottom line business model with building and construction operational activities leverages effective market performance of the small and medium-sized enterprises (SMEs in the building and construction industry, so as to identify major paradoxes and the remedial business model that can be suggested.Research design, approach and method: The study uses interpretivist research paradigm and exploratory qualitative research method to explore the opinions and perceptions of 30 judgementally drawn participants comprising managers and supervisors from 30 building and construction SMEs in Gauteng and KwaZulu-Natal provinces. Thematic analysis was used in the evaluation and interpretation of the interview data collected using a semi-structured interview guide.Main findings: A seemingly greater preponderance to pursue profitability at the expense of people and planet bottom lines was found to be common among most of the SMEs during the initial stages of their establishments and growth because of the need to attain the usually essential initial financial sustainability. Even though on attaining financial sustainability, some of the SMEs strive to achieve all the three bottom lines, most of the undertaken initiatives are often only aimed at improving compliance with relevant building and construction legislations.Managerial implications: The study suggests a modified triple bottom line business model that the SMEs in the building and construction industry can replicate to effectively apply triple bottom line reporting as an edifier for effective market performance.Contributions: The study offers a new theory for measuring the leveraging effects of the triple bottom line business model on the building and

    Health and well-being in the workplace is a concept that is understood as a fundamental business case for a productive, happy and healthy workforce. The workplace is also a setting by which knowledge and skills about health can be disseminated to assist people, in improving their health and well-being. Public health professionals are in a position to develop workplace health and well-being interventions, which support those in jobs and those seeking employment. They can also influence the extent to which work and the workplace affects health and well-being outcomes. This article aims to identify the main health and well-being needs of a sample of small and medium-sized enterprises (SMEs) across Greater Manchester and the support that public health professionals can offer. The research adopted a Health Needs Assessment (HNA) approach using convenience and opportunistic sampling methods, from the list of SMEs in Greater Manchester. The SMEs varied in size and type of business, and 91 telephone interviews, using semi-structured questions, were used to collect data which identified the health and well-being needs of a sample of SMEs in Greater Manchester. This research resulted in qualitative data using thematic analysis. Two key themes emerged from the study. Acute seasonal sickness was the most pressing reason for employee absence from work (viruses, flu, seasonal disorders) for the SMEs in this research. This accumulated to the theme of sickness presenteeism. This research highlighted that employees will present at work with acute illness that requires rest, is easily transmitted to other employees and most likely will take a longer time to recover from as cross infection and re-infection occur. A subsidiary theme was that of authenticity and the reporting of sickness, contributing further to sickness presenteeism as employees seek to legitimise their illness. This article provides issues which are specific to SMEs in Greater Manchester. In particular, the pressing

    Full Text Available A modeling framework is formulated and applied to assess the sensitivity of the hydrological regime of two catchments in a convective rainfall environment with respect to projected climate change. The study uses likely rainfall scenarios with high spatiotemporal resolution that are dependent on projected changes in the driving regional meteorological synoptic systems. The framework was applied to a case study in two medium-sized Mediterranean catchments in Israel, affected by convective rainfall, by combining the HiReS-WG rainfall generator and the SAC-SMA hydrological model. The projected climate change impact on the hydrological regime was examined for the RCP4.5 and RCP8.5 emission scenarios, comparing the historical (beginning of the 21st century and future (mid-21st-century periods from three general circulation model simulations available from CMIP5. Focusing on changes in the occurrence frequency of regional synoptic systems and their impact on rainfall and streamflow patterns, we find that the mean annual rainfall over the catchments is projected to be reduced by 15% (outer range 2–23% and 18% (7–25% for the RCP4.5 sand RCP8.5 emission scenarios, respectively. The mean annual streamflow volumes are projected to be reduced by 45% (10–60% and 47% (16–66%. The average events' streamflow volumes for a given event rainfall depth are projected to be lower by a factor of 1.4–2.1. Moreover, the streamflow season in these ephemeral streams is projected to be shorter by 22% and 26–28% for the RCP4.5 and RCP8.5, respectively. The amplification in reduction of streamflow volumes relative to rainfall amounts is related to the projected reduction in soil moisture, as a result of fewer rainfall events and longer dry spells between rainfall events during the wet season. The dominant factors for the projected reduction in rainfall amount were the reduction in occurrence of wet synoptic systems and the shortening of the wet synoptic systems

    Use of a radioactive liquid waste lagoon by medium-sized mammals and levels of tritium, other selected radionuclides, and metals in biological tissues of the animals were documented at Technical Area 53 (TA-53) of Los Alamos National Laboratory during 1997 and 1998. Rock squirrel (Spermophilus variegates), raccoon (Procyon lotor), striped skunk (Mephitis mephitis), and bobcat (Lynx rufus) were captured at TA-53 and at a control site on the Santa Fe National Forest. Captured animals were anesthetized and marked with radio-frequency identification (RFD) tags and/or ear tags. We collected urine and hair samples for tritium and metals (aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, and thallium) analyses, respectively. In addition, muscle and bone samples from two rock squirrels collected from each of TA-53, perimeter, and regional background sites were tested for tritium, {sup 137}Cs, {sup 90}Sr, {sup 238}Pu, {sup 239,240}Pu, {sup 241}Am, and total uranium. Animals at TA-53 were monitored entering and leaving the lagoon area using a RFID monitor to read identification numbers from the RFID tags of marked animals and a separate camera system to photograph all animals passing through the monitor. Cottontail rabbit (Sylvilagus spp.), rock squirrel, and raccoon were the species most frequently photographed going through the RFID monitor. Less than half of all marked animals in the lagoon area were detected using the lagoon. Male and female rock squirrels from the lagoon area had significantly higher tritium concentrations compared to rock squirrels from the control area. Metals tested were not significantly higher in rock squirrels from TA-53, although there was a trend toward increased levels of lead in some individuals at TA-53. Muscle and bone samples from squirrels in the lagoon area appeared to have higher levels of tritium, total uranium, and {sup 137}Cs than samples collected from perimeter and

    Full Text Available Abstract Background Regular physical activity (PA promotes and excessive sedentary behavior (SB deteriorates health. Yet the Finnish working-aged population spends most of the day sitting. A 1-year Moving To Business (MTB -intervention supported small and medium-size workplaces to combat sedentariness. This paper reports the changes in employees’ PA and SB from before MTB (baseline to 1 year after baseline (follow-up. Methods Twelve workplaces with a total of 396 employees participated. Each workplace nominated a team to promote PA and reduce SB at organizational, working unit and employee level. The teams were mentored regionally through meetings, workshop and tools. Changes in PA and SB were assessed with a questionnaire and an accelerometer. Wald Confidence Interval (Cl for a difference of proportions with matched pairs was used in the questionnaire data (%-points with 95% CI and linear mixed model in the accelerometer data (minutes and % of wear-time with 95% CI.

    Full Text Available The problem of anthropogenic degradation of rivers is usually marked by its multi-sectoral and often international character as well by the large number of sources of environmental threat. Therefore, its solution requires a systematic approach based on transparent and coordinated interagency and international cooperation. The River Dnieper inUkrainehas undergone a remarkable transformation as a result of the construction of a cascade of reservoirs. Anthropogenic damage to the plants and soil that cover its basin have caused damage to the functioning of ecological regimes of theDnieper’s tributaries. Small and medium-sized rivers are dying. In this article, attention is paid to a typical middle-sized (164 km river of theDnieperBasin, the Tyasmyn. Its middle and lower parts are located in the overtransformed Irdyn-Tyasmyn valley. During the last glaciation it formed the central part of the right arm of the ancientDnieper. Regulation of the Tyasmyn runoff, pollution, the creation of theKremenchugreservoir on theDnieper, grazing and recreational load have led to the threat of the river degrading. Therefore, the aim of this article is to characterize the structure of the herbaceous vegetation in the central and lower parts of the Tyasmyn valley and assess the level of its dependence on anthropogenic changes in the conditions of the ecotypes. The methods used are: retrospective and system analysis, comparative ecology (ecological profile or transect, botanic methods, phytoindication, the mapping method and mathematical statistics. The features of changes in environmental conditions of ecotypes of the river valley have been shown through systematic, biomorphological, ecomorphic structure of the herbaceous cover, the ratio of ecological groups and changes in types of ecological strategy of species, phytodiversity. We found 89 species of vascular plants. The most diverse families were Asteraceae, Poaceae and Lamiaceae. The biomorphological range of

    This study investigates the crossover effect of work-life balance (WLB) in the relationship between the management of small and medium-sized enterprises (SMEs) and their employees. SMEs are smaller in scale and have fewer employees than large enterprises, resulting in a close relationship between management and employees. In SMEs, it is easier for employees to observe the daily behavior of the management. Therefore, if management's WLB satisfaction is high, the positive attitude of the manage...

    Full Text Available This study aimed to analyze the impact of the use of ERP systems on organizational efficiency and effectiveness and inter-organizational efficiency of small and medium enterprises in Patos de Minas County. Using a survey adapted from Saccol et al. (2004, the study evaluated the strategic dimensions of customers and consumers, suppliers, market and competitive rivalry and their relationship to organizational efficiency and effectiveness and inter-organizational efficiency, all of which aided by ERP systems. The results showed slight positive relationship in explaining the organizational efficiency and effectiveness and a little higher in inter-organizational efficiency. It is concluded that ERP systems have low relevance to the strategic aspects on small and medium enterprises, confirming the thesis of the need to maturity in the use of information systems to extract strategic benefits.

    Full Text Available We studied the species richness and two indices of abundance of medium-sizedmammals in areas with Andean forest and Andean alder (Alnus acuminatareforestations in a reserve at the Central Andes of Colombia. Since reforested areashave a less complex habitat structure and lower plant diversity than native forests, wepredicted that they have lower richness of mammals than areas with Andean forest.We obtained the indices of abundance from direct contacts in transects and from theuse of track stations. Our results suggest that, indeed, areas with Andean forest hada higher richness of mammals than reforestations, but this pattern may be modifiedby anthropogenic factors. We found no differences between the indices of abundanceof the squirrel, Sciurus granatensis, in the two forest types. In contrast, the coatiswere recorded more frequently in the reforestations than in areas with Andean forestat the reserve.

    The aim of this study was to assess the use of muscle biopsy for histopathological confirmation of small vessel vasculitis (SVV) or medium vessel vasculitis (MVV). Muscle biopsies were performed for all consecutive cases of suspected SVV or MVV seen at Tokyo Metropolitan Tama Medical Centre between February 2012 and May 2014 except those for which a skin or renal biopsy was indicated. Forty-nine patients underwent muscle biopsies. All patients were followed for a minimum of 6 months. Diagnosis of SVV or MVV was made in 35 patients. An unrelated condition was diagnosed in 11 patients and no diagnoses were made in three patients. Of the 35 patients in whom SVV or MVV was diagnosed, positive muscle biopsies were obtained in 20 patients [15 microscopic polyangiitis (MPA), three polyarteritis nodosa (PAN), and two eosinophilic granulomatosis with polyangiitis (EGPA)], while other findings led to the same diagnosis in 15 (seven MPA, four GPA, three PAN, and one rheumatoid vasculitis). The sensitivity of the muscle biopsy was 57% [20/35; 95% confidence interval (CI) 50-57]. Of 13 patients presenting with peripheral neuropathy, the muscle biopsy demonstrated vasculitis in nine patients, with 75% sensitivity (9/12; 95% CI 69-75). There were no complications in the procedure apart from delayed wound healing in one patient. Muscle biopsy is a safe method that offers a high diagnostic yield for SVV or MVV, especially in patients with vasculitic neuropathy.

    According to the major pollution sources of urban water environment, 10 indexes such as industrial sewage quantity were closen to establish evaluation indexes system about the types and influencing factors of the typical and medium-small-sized cities in the southern China. Case studies of 16 typical and medium-small-sized cities were taken in Jiangsu, Zhejiang, Hubei and Anhui provinces. Combined with SPSS 11.0 cluster analysis results, city types were divided in reference to the values of water resources comprehensive pollution indexes and economical development indexes. The driving forces about city water environment pollution were studied by principal component analysis method. The result indicates that the 16 cities belong to two categories and four sub-categories, which are rich economy as well as light pollution of water environment and poor economy as well as heavy pollution of water environment. The influencing factors of water environment pollution are in sequence of industrial water pollution, agricultural no-point source pollution and urban domestic water pollution. The main factors of water environment pollution influenced I category cities, II as well as IV category cities and III category cities are industrial water pollution, urban domestic pollution and agricultural no-point source pollution respectively.

    Existing HPLC methods can provide detailed structure and isomeric information, but are often slow and require large initial sample sizes. In this study, a previously established two-dimensional HPLC technique was adapted to a two-step identification method for smaller sample sizes. After cleavage from proteins, purification, and fluorescent labeling, glycans were analyzed on a 2-mm reverse phase HPLC column on a conventional HPLC and spotted onto a MALDI-TOF MS plate using an automated plate spotter to determine molecular weights. A direct correlation was found for 25 neutral oligosaccharides between the 2-mm Shim-Pack VP-ODS HPLC column (Shimadzu) and the 6-mm CLC-ODS column (Shimadzu) of the standard two- and three-dimensional methods. The increased throughput adaptations allowed a 100-fold reduction in required amounts of starting protein. The entire process can be carried out in 2-3 days for a large number of samples as compared to 1-2 weeks per sample for previous two-dimensional HPLC methods. The modified method was verified by identifying N-glycan structures, including specifying two different galactosylated positional isomers, of an IgG antibody from human sera samples. Analysis of tissue plasminogen activator (t-PA) from CHO cell cultures under varying culture conditions illustrated how the method can identify changes in oligosaccharide structure in the presence of different media environments. Raising glutamine concentrations or adding ammonia directly to the culture led to decreased galactosylation, while substituting GlutaMAX-I, a dipeptide of L-alanine and L-glutamine, resulted in structures with more galactosylation. This modified system will enable glycoprofiling of smaller glycoprotein samples in a shorter time period and allow a more rapid evaluation of the effects of culture conditions on expressed protein glycosylation.

    • Plant light interception efficiency is a crucial determinant of carbon uptake by individual plants and by vegetation. Our aim was to identify whole-plant variables that summarize complex crown architecture, which can be used to predict light interception efficiency. • We gathered the largest database of digitized plants to date (1831 plants of 124 species), and estimated a measure of light interception efficiency with a detailed three-dimensional model. Light interception efficiency was defined as the ratio of the hemispherically averaged displayed to total leaf area. A simple model was developed that uses only two variables, crown density (the ratio of leaf area to total crown surface area) and leaf dispersion (a measure of the degree of aggregation of leaves). • The model explained 85% of variation in the observed light interception efficiency across the digitized plants. Both whole-plant variables varied across species, with differences in leaf dispersion related to leaf size. Within species, light interception efficiency decreased with total leaf number. This was a result of changes in leaf dispersion, while crown density remained constant. • These results provide the basis for a more general understanding of the role of plant architecture in determining the efficiency of light harvesting. © 2011 The Authors.

    Full Text Available Studies of the determinants of export performance include companies located in developed countries and emerging economies. A predominance of studies focusing on large companies in developed countries was observed. The studies tested the RBV and the Uppsala model in isolated ways. The combined use of variables in the models of RBV and Uppsala studies of Brazilian SMEs appear as a gap to be filled in organizational research. This research contributes to theoretical and empirical knowledge involving the phenomena related to the internationalization of Brazilian SMEs by proposing a model integrating these approaches. This research aims identify the determinants of export performance of SMEs in the perspective of RBV and the Uppsala Model. On a survey with 84 SMEs were employed multiple statistical techniques (factor analysis, linear and logistic regression and structural equation modeling. Resources influenced by the idiosyncrasies of the company and its stage of internationalization affected the export performance. Managerial resources were prevalent on organizational resources. Stage of internationalization and exporting time influenced the relationship between export performance and resources. Size and technological intensity not mediated export performance. Resources and stage of internationalization affect the export performance of SMEs. The following question was developed: What are the determinants of export performance of Brazilian manufacturing SMEs? SMEs in emerging countries arouse the attention of governments worldwide since its economic, employment and income opportunities that provide and challenges facing to innovate, promote sustainability, establish and consolidate its internationalization.

    Full Text Available Big Data systems manage and process huge volumes of data constantly generated by various technologies in a myriad of formats. Big Data advocates (and preachers have claimed that, relative to classical, relational/SQL Data Base Management Systems, Big Data technologies such as NoSQL, Hadoop and in-memory data stores perform better. This paper compares data processing performance of two systems belonging to SQL (PostgreSQL/Postgres XL and Big Data (Hadoop/Hive camps on a distributed five-node cluster deployed in cloud. Unlike benchmarks in use (YCSB, TPC, a series of R modules were devised for generating random non-aggregate queries on different subschema (with increasing data size of TPC-H database. Overall performance of the two systems was compared. Subsequently a number of models were developed for relating performance on the system and also on various query parameters such as the number of attributes in SELECT and WHERE clause, number of joins, number of processing rows etc.

    Full Text Available Abstract Background An intravenous urogram (IVU has traditionally been considered mandatory before treating renal and ureteric stones by extracorporeal shock wave lithotripsy (ESWL. This study was designed to see whether there is a difference in complications and the need for ancillary procedures in patients managed by ESWL for renal and ureteric calculi, according to preoperative imaging technique. Methods This retrospective study compared 133 patients undergoing ESWL from January 2001 to July 2002. Patients were divided into three groups according to the preoperative imaging technique used: i IVU; ii non-contrast enhanced helical computed tomography (UHCT; and iii ultrasound (US + X-ray kidney, ureter and bladder (KUB. The groups were matched in terms of age and gender, as well as location, side and size of stones. Results There was no statistically significantly difference for number of ESWL sessions, number of shock waves and use of ancillary procedures between the three groups. The stone-free rate was 98% for the IVU and UHCT groups, and 97% for the US + X-ray KUB group. Conclusions The complication rate and need for ancillary procedures was comparable across the three groups. Patients imaged by UHCT or US + X-ray KUB prior to ESWL for uncomplicated renal and ureteric stones do not require IVU.

    We examined the current status of specialized agencies for occupational health management (SAs) and their workforce. Furthermore, we aimed to clarify the current practice status of SA healthcare professionals and factors that influence their performance. To examine the current SA workforce, we analyzed data from the 2014 Survey of Current Status of SA and their Workforce from the Ministry of Employment and Labor (MOEL). Furthermore, we mailed out an original questionnaire to SA professionals to determine their current health management status and factors that affect their performance. Data from the respondents (N = 384) were analyzed. In 2014, the workforce performing health management in SAs comprised 232 physicians, 507 nurses, and 312 occupational hygienists, with no significant regional differences in the distribution of physicians and nurses. According to the findings of the questionnaire, the average daily number of worker consultations by physicians and nurses was 22.8, while the average time taken for health management ranged from 74.3 to 104.3 min, depending on the size of the firm. Most of the respondents (41.5%) answered that they were following-up on more than 80% of individuals with illnesses. Among health management tasks, performance scores of "consultations for general diseases" and "consultations for lifestyle habits" were relatively high, whereas health promotion activities at workplaces were relatively low. There was a significant correlation between the utilization of general and special health examination results and task performance. Among health management tasks, follow-up management of individuals with illnesses and consultations for disease/lifestyle habits were relatively well performed, whereas health promotion activities at workplaces were not performed well. Among factors that positively influenced SA performance at workplaces, only the utilization of health examination results had significant effects. Therefore, to accomplish

    In order to acquire a representative statement about the effective number of network servers required for nighttime and weekend/public holidays in small and medium-sized companies, a telephone survey was conducted among 400 relevant companies in German-speaking Switzerland. Results: 1) Nowadays, around 80% of small and medium-sized companies in German-speaking Switzerland have an electronic data processing network. 2) The majority of those who have a network leave all their servers running at night (94%) and at the weekend/on public holidays (90%), although about one quarter of the units left on do nothing during the night and almost half do nothing at weekends. 3) About two thirds of the servers which function and carry out tasks during the night need less than three hours to do so. 4) An automatic switching on and off system would be welcomed: 57% of the respondents think the possibility of switching a server on automatically at a specific time or for a specific event would be good. 46% thought the possibility of automatic switch-off of a server when not in use and the simultaneous possibility of switching it on from the workplace. 5) In contrast, the reasons for rejecting these possibilities were rarely based on practical or technical matters but were caused by uncertainties, habits and previously gained convictions or doubts about the technical feasibility. Conclusion: There is a great deal of room to manoeuvre for the introduction of an automatic switch-on and -off system for network servers. Whether this room to manoeuvre can be utilized - alongside of the provision for technologically mature solutions - depends on the success of efforts to convince those responsible for its technical feasibility, its ecological desirability and economical benefits.

    Full Text Available Consulting helps managers or other people find appropriate solutions for challenges they face in their businesses. Most of the losses incurred by the people and the society could be prevented using appropriate consultation. Consultation, also, refers to people's participation in decision making. Despite dramatic development in management consulting industry in the world during the last three decades, consulting industry in Iran has faced numerous challenges. This study aims to examine the factors affecting the efficiency of management consulting services in small and medium-sized businesses and it focuses on food industries in Tehran as a real-world case study. The necessary suggestions regarding the hiring of a consultant and increasing the efficiency of management consulting services in business have been offered in this study. Some recommendations deal with the way that management consultants should respond to the managers' needs, act as a reliable and efficient adviser in public or private businesses and find their position in the Iranian market. The conceptual model of this study shows the influence of key factors affecting the purpose of consulting on the efficiency of management consulting services. To do the research, 90 people are selected as the sample size in a descriptive study with random sampling of the managers of aforementioned companies using a questionnaire. Cronbach’s alpha method was used to assess the reliability of the questionnaire. For assessing the validity of the questionnaire, we use standard questionnaire, which has already been used.

    To control local air quality and to prevent greenhouse gas emissions, the Dutch government has established legislation to restrict such emissions from medium-sized stationary gas engines and heating installations, the so-called Bems legislation. These medium-sized stationary engines, turbines, boilers and other installations are mainly in use in the industry, greenhouse horticulture and services sector. When the Bems legislation entered into force, five possible emission limit values (ELVs) were discussed but not implemented at that time, partly due to the limited availability of knowledge at that time within the market about the required technical measures to meet these ELVs. On request of the Dutch Ministry of Infrastructure and the Environment, the current available knowledge on these five ELVs with respect to NOx, dust and methane emissions, has been explored and the results are discussed in this report. To that purpose, technical knowledge, foreign environmental legislation, potential emission reductions and costs have been analyzed. The ELVs discussed here are set at an O2 concentration of 3% in the flue gas according to Bems legislation. The indicated ELVs have no official status and have a recommendatory meaning to the Dutch Ministry of Infrastructure and the Environment. The Ministry decides on implementation and the value of the discussed ELVs [Dutch] Stookinstallaties kleiner dan 50 MWth dienen aan emissienormen te voldoen, volgens het Besluit emissie-eisen middelgrote stookinstallaties (Bems).

    The aim of this study was to gain insight into worksite health promotion in small and medium-sized companies compared to large concerns in Middle Franconia. Action in worksite health promotion, obstacles and demand for networks for workplace health promotion were determined. A standardised telephone interview served for collecting data for this cross-sectional study. The interviewee was always the manager or their proxy. 106 companies were contacted. The results of this study were analysed via qualitative and quantitative methods in SPSS(®) 20. It was possible to reach and interview 80 companies, a return rate of 75.5%. More than half the companies (68.8%) implemented at least one activity for worksite health promotion, especially ergonomic measures and measures to promote physical activity. Taking the size of the company into consideration when analysing the results, previous study results are confirmed. With an increasing size of the company, the relative frequency of measures for workplace health promotion rises. The motivation for worksite health promotion ranges from keeping the employees healthy (38.2%) to worksite health promotion as part of the business culture (9.1%). 81.1% of the companies consider their activity in worksite health promotion to be successful. Furthermore, 80.0% of the firms that implemented worksite health promotion were supported by a partner like a health insurance (43.2%). Those companies that did not implement any activities for worksite health promotion, state as a prime reason that they did not think about it as yet (44.0%). Besides, 44.0% of the companies without any worksite health promotion would like to implement measures. 65.5% of the companies that already took action in worksite health promotion and 56.0% of the companies that did not would like to cooperate with other firms in a network for workplace health promotion. Mutual exchange is the most important factor for them. The results of this study show that almost half of

    Considerable unused energy (cost) saving potentials exist in the commercial and tertiary sector with its small and medium sized enterprises. Small enterprises mostly need external assistance to improve their energy efficiency, which presents options for services like energy consulting. However those industrial sectors consisting of small and medium sized enterprises have as yet rarely been investigated in regard to opportunities and problems in realizing energy saving measures so that necessary fundamental information is often missing. The objective of the presented thesis is an analysis of energy consumption patterns and measures for reducing energy demand in selected industrial tertiary sectors. Moreover, the objective is an analysis of existing barriers for the realization of energy saving measures in enterprises and a development and examination of tools to overcome identified barriers. Results for the examined sectors Hotels, Laundries, Bakeries and Food Retail show considerable differences in the typical energy usage patterns with industry-specific focus ranging from room heating to process heat for steam- and baking processes to cooling and lighting. The analysis of barriers for the realization of energy saving measures was conducted for two exemplary sectors. Hence, in Hotels exists an important demand for indicators for specific energy consumption and for tools to ascertain and evaluate such energy ratios. The main barriers in the Food Retail sector are the lack of specific information about energy saving options as well as lacking contacts to get assistance. Based on these requirements, for the Hotel sector, a computer program performing energy ratios and carrying out an individual Benchmarking in regard to the sector's average was designed and tested. A seminar including practical training was developed and organized as a tool to overcome barriers in Food Retail enterprises. Both tools, being developed to overcome identified barriers, were

    Small- and medium-sized enterprises (SMEs) have played key roles in the economic growth and technical innovation of traditional and complementary and alternative medicine (T&CM). Research and development (R&D) are critical activities for industrial progress. This study aimed to characterize the current status of SME R&D activities and to explore manufacturers' perceptions of R&D expansion. Records of the distribution of T&CM SMEs and R&D resources detailed in the 2014 Statistics of Korea T&CM Industries survey, a previously conducted survey on the industrial status of the T&CM field, were reviewed. Data on the perceptions of R&D activities were investigated through a company-based survey covering 285 T&CM-manufacturing SMEs. Greater than 99% of the 13,636 T&CM manufacturers at the time of the study were SMEs employing less than 50 workers. Natural cosmetics manufacturing SMEs (NC SMEs) had the highest R&D expenditures. NC SMEs rely heavily on internal R&D operations, which may contribute to their strong need for R&D collaboration with public research institutions and expanded T&CM-promoted R&D programs. "Digestive system disorders" are the main target diseases for current herbal and dietary supplement manufacturing SMEs and herbal medicine manufacturing SMEs. These SMEs tend to view their own product-related business as a priority for future R&D investment. This study represents the first attempt to assess SME perceptions of R&D activities. The findings herein can inform the design of sustainable programs that support R&D by reducing the gaps between the perspectives of T&CM product makers and policymakers.

    Small and Medium-sized Enterprises (SMEs) are the cornerstone of the French economy and job creation. However, due to financial and resource constraints, they are not inclined to look for environmental information autonomously. As a result, they often consider environmental issues as a constraint rather than a potential benefit. SMEs generally invest neither time nor money in order to reduce the environmental impacts of their activities and thus remain in an 'inactivity cycle'. Their global environmental impact cannot be neglected which makes their interested parties more and more concerned. The aim of this study is to analyse the environmental information system of SMEs in order to identify scope for potential improvements. The first hypothesis of this study is that SMEs do not have the knowledge that is necessary in order to implement a 'rational' pollution prevention policy. It is also assumed that access to environmental information is necessary for the SME to reduce the environmental impact of its activities. In order to validate these hypotheses and to identify which information channels contribute to the reduction of environmental impacts, a method is proposed to simultaneously evaluate the environmental policies of the SME and its ability to access to environmental information. This approach has been used to survey 47 SMEs. In addition, more than 300 pieces of information that were given to companies by two industrial associations were analysed. These data were analysed using principal component analysis, multiple correspondence analysis and chi square tests on contingency tables. The survey shows that SMEs favour direct contact with various organisations. The more a company is open to partners, the more it prevents pollution. Each SME has a different 'partnership profile' according to the area where it is situated, its level of independence, its status according to environmental legislation and its situation with respect to

    Full Text Available A violência urbana afeta a vida dos indivíduos, tornando-se um problema complexo de saúde e segurança pública. Buscando avaliar a situação de violência em uma cidade de médio porte, realizou-se um estudo transversal, de base populacional, investigando a prevalência de vitimização por violência urbana para furtos, roubos, agressões e furto/roubo à residência nos últimos cinco anos e 12 meses; e o perfil das vítimas e a prevalência de notificação à polícia. Foi construído um escore a fim de medir a vitimização por pelo menos um dos tipos de violência em cada período. Na análise bruta, a associação entre a vitimização por cada tipo de violência e as variáveis independentes foi investigada através do teste de Wald para heterogeneidade e para tendência linear, quando aplicável. A Regressão de Poisson foi utilizada na análise multivariável. Foram entrevistados 2.912 indivíduos (idade > 20 anos, sendo que 16,6% destes sofreram violência no último ano e 28% nos últimos cinco anos. As maiores prevalências de vitimização foram de furto/roubo à residência (9,7% e furto (6,0%. As principais vítimas de violência urbana foram homens e jovens. Mais da metade dos vitimizados não notificou a ocorrência por não confiar na polícia. Os achados confirmam a importância de pesquisas de vitimização além das metrópoles. As discussões sobre o tema mostram a necessidade de incrementar, executar ou criar políticas públicas de segurança e saúde em distintos contextos nacionais, sem desconsiderar cidades do interior.Urban violence affects individuals' lives, and therefore it is a complex problem of public health and security.

    In this study, the physical and chemical properties of bottom ash and fly ash originating from the co-combustion of biomass-derived fuels (i.e. wood chips, sawdust, bark, and peat) from a 32 MW fluidized bed boiler at a municipal district heating plant were investigated. Silicate minerals were predominant in the bottom ash and calcium minerals in the fly ash, with most of the inorganic nutrients and heavy metals being enriched in the fly ash. The enrichment factors for heavy metals in the fly ash varied between 0.2 for silicon and 16.3 for lead, and for plant nutrients, between 1.5 for phosphorous and 108 for potassium. However, all heavy metal concentrations in both the bottom ash and fly ash were significantly lower than the current Finnish limit for maximum allowable heavy metal concentrations for forest fertilizers, which came into force in March 2007. According to the particle size distribution, the mass loadings of heavy metals in the fly ash were more than 90% contributed by the smallest particle size fraction lower than 0.074 mm. In the bottom ash, between 83.6 and 91.9% of the mass loadings of heavy metals were contributed by the particle size fraction between 0.5 and 2.0 mm. (author)

    The number of pigments in single light-harvesting complexes (chlorosomes) were calculated by imaging single chlorosomes in a frozen buffer at cryogenic temperature with a confocal laser fluorescence microscope and pigment extraction. Chlorosomes were isolated from two types of green photosynthetic bacteria Chlorobium (Chl.) tepidum and Chloroflexus (Cfl.) aurantiacus and were individually imaged in the frozen medium. Each fluorescence spot observed mainly came from a single chlorosome and was ascribable to self-aggregates of bacteriochlorophyll (BChl) c molecules as core parts of chlorosomes. A three-dimensional distribution of fluorescence of single chlorosomes was analyzed, and the number of chlorosomes in a volume of 54,000 microm(3) was counted directly. On the basis of the results, averaged numbers of the BChl c molecules contained in a single chlorosome of Chl. tepidum and Cfl. aurantiacus were determined to be 1.4 x 10(5) and 9.6 x 10(4), respectively. The present numbers are almost comparable to those estimated by other methods (Martinez-Planells et al., Photosynth. Res. 2002, 71, 83 and Montaño et al., Biophys. J. 2003, 85, 2560).

  9. Effective medium theory for anisotropic metamaterials

    Materials with anisotropic material parameters can be utilized to fabricate many fascinating devices, such as hyperlenses, metasolids, and one-way waveguides. In this study, we analyze the effects of geometric anisotropy on a two-dimensional metamaterial composed of a rectangular array of elliptic cylinders and derive an effective medium theory for such a metamaterial. We find that it is possible to obtain a closed-form analytical solution for the anisotropic effective medium parameters, provided the aspect ratio of the lattice and the eccentricity of the elliptic cylinder satisfy certain conditions. The derived effective medium theory not only recovers the well-known Maxwell-Garnett results in the quasi-static regime, but is also valid beyond the long-wavelength limit, where the wavelength in the host medium is comparable to the size of the lattice so that previous anisotropic effective medium theories fail. Such an advance greatly broadens the applicable realm of the effective medium theory and introduces many possibilities in the design of structures with desired anisotropic material characteristics. A real sample of a recently theoretically proposed anisotropic medium, with a near-zero index to control the flux, is achieved using the derived effective medium theory, and control of the electromagnetic waves in the sample is clearly demonstrated.

    This final report for the Swiss Federal Office of Energy (SFOE) reports on research work done on the elimination, concentration or transformation of nitrogen in small and medium-sized agricultural biogas installations. The goal of the project - the conception of a state of the art on existing, economically feasible technologies or processes to treat the nitrogen produced in anaerobic digestion - is discussed. Typical Swiss small/medium size agricultural biogas plants with an electrical power of around 100 kW from its combined heat and power generation (CHP) unit are examined. A reference installation is discussed which treats cow slurry, organic restaurant waste, used vegetable oils, bakery wastes, coffee grounds, and cereal wastes. A literature research is described which was conducted to find information regarding available treatment techniques for slurry and digestate treatment. Information from Switzerland, France, Belgium, the Netherlands, Germany and Austria was used. Various techniques are examined including a screw-press separator, a centrifuge, membrane filtration, air stripping with acid wash, air stripping with catalytic combustion, evaporation, band dryer, precipitation, composting and biological treatment. The economic analysis and the comparison between techniques are quoted as being coarse as they are based on numerous assumptions.

    size: 8pt;">The purpose of the paper is to analyse the obstacles to implementing social responsibility initiatives in small and medium-size business firms. The implementing fields and the importance of corporate social responsibility (CSR initiatives in small and medium-size business firms are stressed in the paper. The current situation of CSR in Lithuanian small and medium-size firms is presented. The research data allowed discovering that the main obstacle to implement social responsibility in the small and medium-size firms is the managers’ attitude that social responsibility is a matter of great concern only to large companies. 43% of respondents indicated this obstacle. On the other hand, the research data allowed finding out that in our turbulent environment social responsibility in small and medium-size business firms is not a random phenomenon (71 %, and it is constant concern to managers, which provides for the budget (54 %. The understanding that social responsibility initiatives are only charity or philanthropy is also declined, only 5% of the respondents think so, however, 32 % of firms are supporting charitable initiatives. The most stimulating factors in the implementation of CSR are: staff loyalty and job satisfaction, a better image of the company, long-term competitiveness of the business advantage, the increased consumers requirements. Socially responsible behaviour disincentives are: the lack of human resour-ces (51 %, lack of information about gain from socially responsible activities (50 %, lack of financial resources (28 %. Both theory and practice agree that the implementation of CSR issues is most dependent on the leader’s attitude. The managers of small and medium-size business firms mostly are coordinating the implementation of CSR initiatives (70% of respondents. The results of the empirical

    Full Text Available The total leaf area (TLA estimation is an important feature of the crops and their assessment a challenge, since the direct methods of obtaining it are destructive and time consuming. Non-destructive methods have been explored to obtain the TLA by indirect approaches, in turn creating other features, as the leaf area index. The development of non-destructive technology to access the TLA of a plant has been the subject of much research, and the optical metrology is an promising approach. In this work, some indirect methods associated with optical approaches were evaluated as an alternative to obtain the TLA of the coffee plant. Commercial equipment were used, such as a camera with a fish eye lens and lux meters, associated to the sizes of the canopies were tested and compared to another non-destructive method and with methods proposed in the literature. The association between production and the TLA estimated was also evaluated. The results showed that the commercial equipment, generally used in forestry, was not the best approach in coffee plants, and that the methods related to the size and lux values of the plants were the best alternatives to estimate the TLA of the coffee plant.A estimativa da área foliar total (AFT é uma importante característica das culturas cuja avaliação é um desafio visto que métodos diretos de obtê-la são destrutivos e consome tempo.

    Describing interstellar matter in our galaxy in all of its various forms, this book also considers the physical and chemical processes that are occurring within this matter. The first seven chapters present the various components making up the interstellar matter and detail the ways that we are able to study them. The following seven chapters are devoted to the physical, chemical and dynamical processes that control the behaviour of interstellar matter. These include the instabilities and cloud collapse processes that lead to the formation of stars. The last chapter summarizes the transformations that can occur between the different phases of the interstellar medium. Emphasizing methods over results, "The Interstellar Medium" is written for graduate students, for young astronomers, and also for any researchers who have developed an interest in the interstellar medium.

    Full Text Available Pattern of attack of a galling insect reveals an unexpected preference-performance linkage on medium-sized resources. The Plant Vigor Hypothesis (PVH predicts oviposition preference and higher offspring performance on longer and fast-growing shoots, and although several studies have tested its predictions, long-term studies concerning the patterns of host selection by galling species are still lacking. The PVH was tested in this study using Bauhinia brevipes (Fabaceae as the host of a leaf gall midge, Asphondylia microcapillata (Diptera, Cecidomyiidae during three consecutive years. Shoots were collected from the same 80 plants between 2001 and 2003 and shoot length, number of healthy and galled leaves, gall number, and mortality factors were recorded. Nearly 600 galls were found on the 5,800 shoots collected. Medium-sized shoots supported from 46 to 70% of all galls, with greater gall survival rate in 2002 and 2003. A decrease in parasitism rate coupled with an increase in gall predation lead to a constant similar gall survivorship rate in all years (x = 22.7%. Although gall abundance varied among years (122 in 2001, 114 in 2002 and 359 in 2003 preference for longer shoots was not observed because the percentage of galled shoots and galled leaves were higher on medium shoot length classes in all years. The observed distribution of gall abundance and galled shoots were always greater than the expected distribution on medium shoot length classes. These findings do not support the PVH, and show that A. microcapillata can maximize the female preference and larval performance on medium-sized shoots of B. brevipes.A Hipótese do Vigor de Plantas (HVP prevê uma oviposição preferencial e alta performance da prole em ramos longos e de crescimento rápido da planta hospedeira.

  20. Interference Phenomena in Medium Induced Radiation

    Casalderrey-Solana, Jorge

    2011-01-01

    We consider the interference pattern for the medium-induced gluon radiation produced by a color singlet quark-antiquark antenna embedded in a QCD medium with size $L$ and `jet quenching' parameter $\\hat q$. Within the BDMPS-Z regime, we demonstrate that, for a dipole opening angle $\\theta_{q\\bar q} \\gg\\theta_c\\equiv {2}/{\\sqrt{\\hat q L^3}}$, the interference between the medium--induced gluon emissions by the quark and the antiquark is suppressed with respect to the direct emissions. This is so since direct emissions are delocalized throughout the medium and thus yield contributions proportional to $L$ while interference occurs only between emissions at early times, when both sources remain coherent. Thus, for $\\tqq \\gg\\theta_c$, the medium-induced radiation is the sum of the two spectra individually produced by the quark and the antiquark, without coherence effects like angular ordering. For $\\tqq \\ll\\theta_c$, the medium--induced radiation vanishes.
