Synthesis of fused cyclic systems containing medium-sized rings through tandem ROM-RCM of norbornene derivatives embedded in a carbohydrate template

A general approach for the synthesis of fused cyclic systems containing medium-sized rings (7-9) has been developed. The key steps involve a diastereoface-selective Diels-Alder reaction of the dienophiles 4a-d attached to a furanosugar with cyclopentadiene and ring opening (ROM)-ring closing metathesis (RCM) of the resulting norbornene derivatives 10a-d and 11a-d. Diels-Alder reaction of the dienophiles 4a-d with cyclopentadiene in the absence of a catalyst produced 10a-d as the major product arising through addition of the diene to the unhindered Si-face. The most interesting and new aspect of the Diels-Alder reaction of these dienophiles is the accessibility of the Re-face that was blocked by the alkenyl chains under Lewis acid catalysis producing the diastereoisomers 11a-d exclusively. The reversal of facial selectivity from an uncatalyzed reaction to a catalyzed one is unprecedented. The observed stereochemical dichotomy is attributed to rotation of the enone moiety along the or bond linking the sugar moiety during formation of the chelate 13. This makes the Re-face of the enone moiety in 4a-d unhindered. Diels-Alder reaction of the carbocyclic analogue 15 under Lewis acid catalysis produced a 1: 1 mixture of the adducts 16 and 17 confirming the participation of sugar ring oxygen in chelate formation. Finally ROM-RCM of 10a-d and 11a-d with Grubbs' catalyst afforded the cis-syn-cis and cis-anti-cis bicyclo-annulated sugars 21a-d and 23a-d, respectively, containing 7-9 membered rings.

The STRATADAPT scale: a measure of marketing strategy adaptation to international business markets

Purpose – The development of marketing strategies optimally adjusted to export markets has been a vitally important topic for both managers and academics for about five decades. However, there is no agreement in the literature about which elements integrate marketing strategy and which components of domestic strategies should be adapted to export markets. The purpose of this paper is to develop a new scale – STRATADAPT. Design/methodology/approach – Results from a sample of small and medium-sized industrial exporting firms support a four-dimensional scale – product, promotion, price, and distribution strategies – of 30 items. The scale presents evidence of composite reliability as well as discriminant and nomological validity. Findings – Findings reveal that all four dimensions of marketing strategy adaptation are positively associated with the amount of the firm's financial resources allocated to export activity. Practical implications – The STRATADAPT scale may assist managers in developing better international marketing strategies as well as in planning more accurate and efficient marketing programs across markets. Originality/value – This study develops a new scale, the STRATADAPT scale, which is a broad measure of export marketing strategy adaptation.

Comparing methods for sampling large- and medium-sized mammals: camera traps and track plots

Activities involving fauna monitoring are usually limited by the lack of resources; therefore, the choice of a proper and efficient methodology is fundamental to maximize the cost-benefit ratio. Both direct and indirect methods can be used to survey mammals, but the latter are preferred due to the difficulty to come in sight of and/or to capture the individuals, besides being cheaper. We compared the performance of two methods to survey medium and large-sized mammal: track plot recording and camera trapping, and their costs were assessed. At Jatai Ecological Station (S21 degrees 31`15 ``- W47 degrees 34`42 ``-Brazil) we installed ten camera traps along a dirt road directly in front of ten track plots, and monitored them for 10 days. We cleaned the plots, adjusted the cameras, and noted down the recorded species daily. Records taken by both methods showed they sample the local richness in different ways (Wilcoxon, T=231; p;;0.01). The track plot method performed better on registering individuals whereas camera trapping provided records which permitted more accurate species identification. The type of infra-red sensor camera used showed a strong bias towards individual body mass (R(2)=0.70; p=0.017), and the variable expenses of this method in a 10-day survey were estimated about 2.04 times higher compared to track plot method; however, in a long run camera trapping becomes cheaper than track plot recording. Concluding, track plot recording is good enough for quick surveys under a limited budget, and camera trapping is best for precise species identification and the investigation of species details, performing better for large animals. When used together, these methods can be complementary.

An aproach for implementing knowledge management in small and medium companies in Brazil: A case study

The search for competitive advantage in a global environment must consider the use of tacit and explicit knowledge circulating inside companies. Differential factors can be easily replicated nowadays. Due to the great volume of knowledge and information, it is necessary to create a system that allows the management of important knowledge. Existing models for Knowledge Management are based on the reality at large companies. In Brazil, most of the companies are smaller ones. This work presents a simplified model to implement Knowledge Management in Small and Medium Companies in Brazil, based on a unique case study with limited scope. Despite some human and financial restrictions, Knowledge Management can help smaller companies, preserving organizational memory and increasing process efficiency. Observing a unique case prevented any generalization of the model. But the recommendations can be references to other companies, because projects like this must address the specific issues of each organization. The objective of this study is to introduce a simplified model for planning Knowledge Management at small companies in Brazil, considering their restrictions and also seeking to create a competitive advantage. Human aspects are very important in Knowledge Management, but that is not the focus of this study. The model was conceived presuming the participation of all people involved.

Chronic reparative changes in medium-sized vessels in a case of primary cutaneous anaplastic large-cell lymphoma with angioinvasive features and cytotoxic phenotype: new histopathological findings in line with indolent clinical behavior

Angioinvasion/angiodestruction has been reported in a small subset of primary cutaneous anaplastic large-cell lymphomas (PCALCL). Recently, PCALCL with angioinvasive features and cytotoxic phenotype has been characterized as a variant associated with good clinical outcomes despite worrisome histopathologic features. We report a case of PCALCL with angioinvasive features and cytotoxic phenotype associated with reparative changes on the wall of medium-sized vessels involved by the neoplasm, including intimal fibroblastic proliferation and luminal obliteration. This vascular pattern, although previously unreported in PCALCL, is in accordance with the indolent behavior observed in this entity and provides a further link with lymphomatoid papulosis type E.

Factors associated with physical-activity performance by older individuals in a medium-sized city in São Paulo State, Brazil

Physical activity has been scientifically discussed as fundamental in the process of healthy ageing. Hence, this study aimed at determining the factors that influence older people to perform physical activities. The complete IPAQ (International Physical Activity Questionnaire) was applied to a population-based sample consisting of 364 elderly persons in the city of Botucatu, São Paulo, Brazil. Days of physical activity performed by the older people were considered by taking into account household and leisure activities. Models for count data were fitted by including socio-demographic variables as well as those related to life satisfaction. It was shown that housework physical-activity performance is associated with female, who predominantly showed to be more active in all levels. Male seemed to be more predisposed to perform lighter recreation, sports and leisure-time physical activities, such as walking. Additionally, poor schooling showed to be decisive for not performing physical activities both at home and during leisure.

Use of outdoor ranges by laying hens in different sized flocks.

In studies assessing outdoor range use of laying hens, the number of hens seen on outdoor ranges is inversely correlated to flock size. The aim of this study was to assess individual ranging behavior on a covered (veranda) and an uncovered outdoor run (free-range) in laying hen flocks varying in size. Five to ten percent of hens (aged 9–15 months) within 4 small (2–2500 hens), 4 medium (5–6000), and 4 large (≥9000) commercial flocks were fitted with radio frequency identification (RFID) tags. Antennas were placed at both sides of all popholes between the house and the veranda and the veranda and the free-range. Ranging behavior was directly monitored for approximately three weeks in combination with hourly photographs of the free-range for the distribution of hens and 6h long video recordings on two parts of the free-range during two days. Between 79 and 99% of the tagged hens were registered on the veranda at least once and between 47 and 90% were registered on the free-range at least once. There was no association between the percentage of hens registered outside the house (veranda or free-range) and flock size. However, individual hens in small and medium sized flocks visited the areas outside the house more frequently and spent more time there than hens from large flocks. Foraging behavior on the free-range was shown more frequently and for a longer duration by hens from small and medium sized flocks than by hens from large flocks. This difference in ranging behavior could account for the negative relationship between flock size and the number of hens seen outside at one point of time. In conclusion, our work describes individual birds’ use of areas outside the house within large scale commercial egg production.

Factors Underlying the Formation of Industrial Clusters in Japan and Industrial Cluster Policy: A Quantitative Survey

The purpose of this report is to use information provided by a questionnaire survey to analyze the factors and processes underlying the formation of industrial clusters in Japan. The study, based on questionnaire surveys, forms part of an "Industrial Cluster Project". The Japanese government has implemented policies for industrial clusters so as to enable Japanese industries to maintain competitive power in global markets, and to aid the self-sufficient expansion of local industries. The government's project goes under the heading "Industry Agglomeration for the Recovery of Local Industries with respect to so-called "Industry Clusters." The authors aim to identify what expectations are held of government by the enterprises that make up industrial clusters. As part of our investigation, we used the results of a survey conducted by UNDP in 2004. Tsuji's study, published by the Osaka School of International Public Policy, surveyed 1198 small or medium sized manufacturing companies located in O ward, Tokyo and Higashi Osaka city, Osaka prefecture. The outcome of the present study, together with data from Tsuji's work on IT usage by SMEs in Japan, is meant to form the basis for policy design and implementation.

E-CRM in SMEs: an exploratory study in Sangammer region of Maharashtra in India

Although there are many definitions of SME's there is no globally accepted definition of a small or medium-sized enterprise. Small Medium Enterprises (SME) the catalyst in economic growth & development of the country, are facing tough competition in market place and in establishing themselves as credible supplier of quality product and services. In India they are producing more than 8000 different products. The common perception is that small to medium businesses have very little options in terms of CRM solutions. This is clearly not the case. SME's now have a lot of options and can exercise same. Businesses are shifting from product centric to customer centric. Long before the advent of technology, businesses have always recognized that the customer is the soul of every business. Businesses try to have personal relationship with their customers. Moving towards customer centric approach is a multi prolonged efforts that requires transformation of process, culture and strategy from top level to every individual employee. Technology has a crucial role in providing tools and infrastructure to support this. CRM supports SMEs in their business customer loyalty.

Hands-on training in Nonimaging Optics for SME's: the SMETHODS experience

A 5-day training in Nonimaging Optics for European SME’s employees was carried out in June 2012 in the framework of the FP7 funded Support Action "SMETHODS". The training combined theoretical introduction and hands-on practice. The experience was very positive, and the lessons learned will improve the next scheduled sessions. Introduction The FP7 funded Support Action "SMETHODS" [1] is an initiative of seven European academic institutions to strengthen Europe's optics and photonics industry, which has started on 1 September 2011. Participation in training sessions is free for participants, who are selected with priority will be given to employees of small and medium sized European enterprises (SMEs). The consortium in SMETHODS is formed by seven partners that are the most prominent academic institutions in optical design in their countries. Through fully integrated collaborative training sessions, the consortium provides professional assistance as well as hands-on training in a variety of design tasks in four domains: (1) imaging optics, (2) nonimaging optics, (3) wave optics, and (4) diffractive optics. For each of this domains domain, 5-day training sessions are scheduled to be hold in different locations throughout Europe, four times in two years, the teach four times in a 2.5 years period.

Metamodelo para la definición, implantación y mejora de los procesos de gestión de proyectos

En los últimos años hemos sido testigos de la creciente demanda de software para resolver problemas cada vez más complejos y de mayor valor agregado. Bajo estas circunstancias, nos podemos hacer la siguiente pregunta: ¿Está preparada la industria de software para entregar el software que se necesita en los próximos años, de acuerdo con las demandas del cliente? Hoy en día, muchos expertos creen que el éxito de esta industria dependerá de su capacidad para gestionar los proyectos, las personas y los recursos. En este sentido, la gestión de proyectos es un factor clave para el éxito de los proyectos software en todo el mundo. Además, considerando que las Pequeñas y Medianas Empresas de software (PYMEs) representan el 99,87% de las empresas españolas, es vital para este tipo de empresas la implementación de los procesos involucrados con la gestión de proyectos. Es cierto que existen muchos modelos que mejoran la eficacia de la gestión de proyectos, pero la mayoría de ellos se centra únicamente en dos procesos: la planificación del proyecto y la monitorización y control del proyecto, ninguno de los cuales a menudo es asequible para las PYMEs. Estos modelos se basan en el consenso de un grupo de trabajo designado para establecer cómo debe ser gestionado el proceso software. Los modelos son bastante útiles ya que proporcionan lineamientos generales sobre dónde empezar a mejorar la gestión de los proyectos, y en qué orden, a personas que no saben cómo hacerlo. Sin embargo, como se ha dicho anteriormente, la mayoría de estos modelos solamente funcionan en escenarios dentro de las grandes empresas. Por lo tanto, es necesario adaptar los modelos y herramientas para el contexto de PYMEs. Esta tesis doctoral presenta una solución complementaria basada en la aplicación de un metamodelo. Este metamodelo es creado para mejorar la calidad de los procesos de la gestión de proyectos a través de la incorporación de prácticas eficaces identificadas a través del análisis y estudio de los modelos y normas existentes relacionadas con la gestión de proyectos. viii ProMEP – Metamodelo para la gestión de proyectos Por lo tanto, el metamodelo PROMEP (Gestión de Proyectos basada en Prácticas Efectivas) permitirá establecer un proceso estándar de gestión de proyectos que puede adaptarse a los proyectos de cada empresa a través de dos pasos: En primer lugar, para obtener una fotografía instantánea (o base) de los procesos de gestión de proyectos de las PYMEs se creó un cuestionario de dos fases para identificar tanto las prácticas realizadas y como las no realizadas. El cuestionario propuesto se basa en el Modelo de Madurez y Capacidad Integrado para el Desarrollo v1.2 (CMMI-DEV v1.2). Como resultado adicional, se espera que la aplicación de este cuestionario ayude a las PYMEs a identificar aquellas prácticas que se llevan a cabo, pero no son documentadas, aquellas que necesitan más atención, y aquellas que no se realizan debido a la mala gestión o al desconocimiento. En segundo lugar, para apoyar fácilmente y eficazmente las tareas de gestión de proyectos software del metamodelo PROMEP, se diseñó una biblioteca de activos de proceso (PAL) para apoyar la definición de los procesos de gestión de proyectos y realizar una gestión cuantitativa de cada proyecto de las PYMEs. Ambos pasos se han implementado como una herramienta computacional que apoya nuestro enfoque de metamodelo. En concreto, la presente investigación propone la construcción del metamodelo PROMEP para aquellas PYMEs que desarrollan productos software de tal forma que les permita planificar, monitorizar y controlar sus proyectos software, identificar los riesgos y tomar las medidas correctivas necesarias, establecer y mantener un conjunto de activos de proceso, definir un mecanismo cuantitativo para predecir el rendimiento de los procesos, y obtener información de mejora. Por lo tanto, nuestro estudio sugiere un metamodelo alternativo para lograr mayores niveles de rendimiento en los entornos de PYMEs. Así, el objetivo principal de esta tesis es ayudar a reducir los excesos de trabajo y el tiempo de entrega, y aumentar así la calidad del software producido en este tipo de organizaciones. Abstract In recent years we have been witnessing the increasing demand for software to solve more and more complex tasks and greater added value. Under these circumstances, we can ourselves the following question: Is the software industry prepared to deliver the software that is needed in the coming years, according to client demands? Nowadays, many experts believe that the industry’ success will depend on its capacity to manage the projects, people and resources. In this sense, project management is a key factor for software project success around the world. Moreover, taking into account that small and medium-sized software enterprises (SMSe) are the 99.87% of the Spanish enterprises, it is vital for this type of enterprises to implement the processes involved in project management. It is true that there are many models that improve the project management effectiveness, but most of them are focused only on two processes: project planning and project monitoring and control, neither of which is affordable for SMSe. Such models are based on the consensus of a designated working group on how software process should be managed. They are very useful in that they provide general guidelines on where to start improving the project management, and in which order, to people who do not know how to do it. However, as we said, the majority of these models have only worked in scenarios within large companies. So, it is necessary to adapt these models and tools to the context of SMSe. A complementary solution based on the implementation of a metamodel is presented in this thesis. This metamodel is created to improve the quality of project management processes through the incorporation of effective practices identified through the analysis and study of relevant models and standards related to project management. Thus, the PROMEP (PROject Management based on Effective Practices) metamodel will allow establishing a project management standard process to be tailored to each enterprise’s project through two steps: Firstly, to obtain a baseline snapshot of project management processes in SMSe a two-phase questionnaire was created to identify both performed and nonperformed practices. The x ProMEP – Metamodelo para la gestión de proyectos proposed questionnaire is based on Capability Maturity Model Integration for Development v1.2. As additional result, it is expected that the application of the questionnaire to the processes will help SMSe to identify those practices which are performed but not documented, which practices need more attention, and which are not implemented due to bad management or unawareness. Secondly, to easily an effectively support the software project management tasks in the PROMEP metamodel, a Process Asset Library (PAL) is designed to support the definition of project management processes and to achieve quantitative project management in SMSe. Both steps have been implemented as a computational tool that supports our metamodel approach. Concretely, the present research proposes the accomplishment of the PROMEP metamodel for those SMSe which develop software products and enable them to plan, supervise and control their software projects, identify risks and take corrective actions, establish and maintain a set of process assets, define quantitative models that predict the process performance, and provide improvement information. So, our study suggests an alternative metamodel to achieve higher performance levels in the SMSe environments. The main objective of this thesis is help to reduce software overruns and delivery time, and increase software quality in these types of organizations.

Asset-backed securities: The key to unlocking Europe's credit markets? Bruegel Policy Contribution 2014/07, 24 July 2014

The European market for asset-backed securities (ABS) has all but closed for business since the start of the economic and financial crisis. ABS (see Box 1) were in fact the first financial assets hit at the onset of the crisis in 2008. The subprime mortgage meltdown caused a deterioration in the quality of collateral in the ABS market in the United States, which in turn dried up overall liquidity because ABS AAA notes were popular collateral for inter-bank lending. The lack of demand for these products, together with the Great Recession in 2009, had a considerable negative impact on the European ABS market. The post-crisis regulatory environment has further undermined the market. The practice of slicing and dicing of loans into ABS packages was blamed for starting and spreading the crisis through the global financial system. Regulation in the post-crisis context has thus been relatively unfavourable to these types of instruments, with heightened capital requirements now necessary for the issuance of new ABS products. And yet policymakers have recently underlined the need to revitalise the ABS market as a tool to improve credit market conditions in the euro area and to enhance transmission of monetary policy. In particular, the European Central Bank and the Bank of England have jointly emphasised that: “a market for prudently designed ABS has the potential to improve the efficiency of resource allocation in the economy and to allow for better risk sharing... by transforming relatively illiquid assets into more liquid securities. These can then be sold to investors thereby allowing originators to obtain funding and, potentially, transfer part of the underlying risk, while investors in such securities can diversify their portfolios... . This can lead to lower costs of capital, higher economic growth and a broader distribution of risk” (ECB and Bank of England, 2014a). In addition, consideration has started to be given to the extent to which ABS products could become the target of explicit monetary policy operations, a line of action proposed by Claeys et al (2014). The ECB has officially announced the start of preparatory work related to possible outright purchases of selected ABS1. In this paper we discuss how a revamped market for corporate loans securitised via ABS products, and how use of ABS as a monetary policy instrument, can indeed play a role in revitalising Europe’s credit market. However, before using this instrument a number of issues should be addressed: First, the European ABS market has significantly contracted since the crisis. Hence it needs to be revamped through appropriate regulation if securitisation is to play a role in improving the efficiency of resource allocation in the economy. Second, even assuming that this market can expand again, the European ABS market is heterogeneous: lending criteria are different in different countries and banking institutions and the rating methodologies to assess the quality of the borrowers have to take these differences into account. One further element of differentiation is default law, which is specific to national jurisdictions in the euro area. Therefore, the pool of loans will not only be different in terms of the macro risks related to each country of origination (which is a ‘positive’ idiosyncratic risk, because it enables a portfolio manager to differentiate), but also in terms of the normative side, in case of default. The latter introduces uncertainties and inefficiencies in the ABS market that could create arbitrage opportunities. It is also unclear to what extent a direct purchase of these securities by the ECB might have an impact on the credit market. This will depend on, for example, the type of securities targeted in terms of the underlying assets that would be considered as eligible for inclusion (such as loans to small and medium-sized companies, car loans, leases, residential and commercial mortgages). The timing of a possible move by the ECB is also an issue; immediate action would take place in the context of relatively limited market volumes, while if the ECB waits, it might have access to a larger market, provided steps are taken in the next few months to revamp the market. We start by discussing the first of these issues – the size of the EU ABS market. We estimate how much this market could be worth if some specific measures are implemented. We then discuss the different options available to the ECB should they decide to intervene in the EU ABS market. We include a preliminary list of regulatory steps that could be taken to homogenise asset-backed securities in the euro area. We conclude with our recommended course of action.
