A framework for enabling dynamic e-business strategies via new enterprise paradigms and ERP solutions

In the global Internet economy, e-business as a driving force to redefine business models and operational processes is posing new challenges for traditional organizational structures and information system (IS) architectures. These are showing promises of a renewed period of innovative thinking in e-business strategies with new enterprise paradigms and different Enterprise Resource Planning (ERP) systems. In this chapter, the authors consider and investigate how dynamic e-business strategies, as the next evolutionary generation of e-business, can be realized through newly diverse enterprise structures supported by ERP, ERPII and so-called "ERPIII" solutions relying on the virtual value chain concept. Exploratory inductive multi-case studies in manufacturing and printing industries have been conducted. Additionally, it proposes a conceptual framework to discuss the adoption and governance of ERP systems within the context of three enterprise forms for enabling dynamic and collaborative e-business strategies, and particularly demonstrate how an enterprise can dynamically migrate from its current position to the patterns it desires to occupy in the future - a migration that must and will include dynamic e-business as a core competency, but that also relies heavily on ERP-based backbone and other robust technological platform and applications.

Violence against women in Ethiopia

Investigating the experience of violence against women and exploring women's coping strategies is a crucial component of re-tailoring the provision of services for victims/survivors. This article explores violence against women in the context of culture, theory of fear of violence and literature on spaces perceived to be 'safe' or 'dangerous' by women victims/survivors of violence in Ethiopia. To collect the relevant data, we conducted 14 semi-structured interviews with Ethiopian women who are victims/survivors of violence and three interviews with gender experts in Ethiopia. Our group of women suffer in 'silence' and confide only in friends and relatives. They did not resort to institutional support due to lack of awareness and general societal disapproval of such measures. This contrasts with claims by experts that the needs of these women are addressed using an institutional approach. Culture, migration status and lack of negotiating power in places of work are key factors when considering violence. The majority of the respondents in this study occupy both public and private spaces such as bars and homes and have experienced violence in those spaces. The social relations and subsequent offences they endured do not make spaces such as these safe. Education of both sexes, creation of awareness, sustainable resource allocation to support victims/survivors, ratification of the Maputo protocol and effective law enforcement institutions are some of the practical strategies we propose to mitigate the incidence of violence in Ethiopia. © 2010 Taylor & Francis.

Európai lepkeszúnyog fajok potenciális elterjedése a 21. században

Leishmaniasis is a typical vectorial disease transmitted by Psycodidae vectors (Lutzomyans, Phlebotomus species). The worldwide observed 1,5-2 million new cases and 60,000 death caused by Leishmania parasites per year make leishmaniasis is one of the most important vectorial disease in the tropicals and warm temperate areas of the World. In the human environment dogs and cats are the most important hosts of the different leishmania agents. The different leishmania species cause symptomatically cutan or visceral disease forms, but many other type of the disease has recognised. Phlebotomus species are sensitive to climatic patterns, they require hight relative air humidity, mild winters and long and warm vegetation period, but the environmental requirements of the species naturally is not the same. Due to climate change in the near future the climate of Western and Central Europe could allow the colonisation of these highly populated areas with also the vectors and the parasites. Our aim was to analyse the environmental patterns of the current distribution area of 8 important sand flies (P. ariasi, P. perniciosus, P. perfiliewi, P. papatasi, P. tobbi, P. neglectus, P. similis and P. sergenti) using the 1960-1990 period’s climate as reference. Using climate envelope modeling we determined these climatic characters and using the REMO climate projection we created the recent and the near-future (2011-2040 and 2041-2070) potential distribution area of the sand flies. The current known area of many Phlebotomus species restricted either to the western or to the eastern Mediterranean Basin. We found that their climatic requirements are could not explain their segregation, it is maybe the consequence of their evolutionary history (geographical barriers and paleoclimatic history). By the end of the 2060’s most parts of Western Europe can be colonized by sand flies, mostly by P. ariasi and P. pernicosus. P. ariasi showed the greatest potential northward expansion. Our model resulted 1 to 2 months prolongation of the potentially active period of P. neglectus P. papatasi and P. perniciosus for the 2070’s in Southern Hungary. As the climate becomes drier and warmer, sand flies will occupy more and more parts of Hungary. Our findings confirm the concerns that leishmanisais can become a real hazard for the major part of the European population to the end of the 21th century and the Carpathian Basin is a particularly vulnerable area.

Grandfamilies: Grandchildren raised by grandparents. Impact on students and school services

Historically, some grandparents have had to assume the responsibility for raising their grandchildren. More recently, with increasing frequency grandparents are serving as full-time surrogate parents to their grandchildren.^ The term "grandfamily" was coined by this researcher to identify families where children are raised by grandparents. "Supergrands" are the grandparents and "grandkin" are children in these families.^ Supergrands who raise their grandkin tend to have elevated levels of stress that negatively impact their well-being. Grandkin tend to develop problems with attachment and establishing social networks, which can lead to poor psychological adjustment. School personnel believe grandkin evidence behavioral problems and occupy disproportionate amounts of their time each day. However, there is a dearth of data to support this belief.^ This study empirically investigated the impact of grandfamilies on students and school services. The results revealed grandkin experienced significantly greater levels of emotional and behavior problems than similar schoolmates. However, they were not referred for discipline problems in substantially larger numbers.^ These results indicate the practice of education should change to allow for the development and provision of social support procedures in schools. Social support will serve to buffer the stress, manifested in emotional and behavioral problems, encountered by children living with surrogate parents. A case study was presented along with a proposed intervention project that has potential to ameliorate the problems experienced by grandfamilies. ^

La novela del burdel: Hacia una poetica del espacio prostibulario en la narrativa hispanoamericana

The brothel, as a ‘symbolic location’ was the object of analysis in this dissertation, ascribable to its unusual and recurrent presence in Latin American narrative. The brothel was presented as a scenario, with polyvalent implications of both the space itself, as well as the different archetypes of the characters who occupy it. ^ Our analysis showed how the brothel functions as a cultural entity, social archetype, power center, mythical place and symbolic space, where man plays out his utmost dominant self. To achieve this, the analysis focused on sifting through the concepts of machismo, economic and political power, and the configuration of the ‘house’ as emblematic elements of Latin American culture. ^ The four novels chosen to underwrite this analysis were representative of the historical time frame, from Colonial times to the present, highlighting all the most distinctive features. These, in turn, led the reader to the inescapable fact that owing to certain characteristics of Latin American culture, the brothel maintains its raison d'être as a space that represents existential situations, and that far from converting itself into an anachronism, it will continue to thrive in the most significant achievements of Latin American prose. ^

An analysis of completeness and historical accuracy in the most commonly used college jazz history texts

Historical accuracy is only one of the components of a scholarly college textbook used to teach the history of jazz music. Textbooks in this field should include accurate ethnic representation of the most important musical figures as jazz is considered the only original American art form. As college and universities celebrate diversity, it is important that jazz history be accurate and complete. ^ The purpose of this study was to examine the content of the most commonly used jazz history textbooks currently used at American colleges and universities. This qualitative study utilized grounded and textual analysis to explore the existence of ethnic representation in these texts. The methods used were modeled after the work of Kane and Selden each of whom conducted a content analysis focused on a limited field of study. This study is focused on key jazz artists and composers whose work was created in the periods of early jazz (1915-1930), swing (1930-1945) and modern jazz (1945-1960). ^ This study considered jazz notables within the texts in terms of ethnic representation, authors' use of language, contributions to the jazz canon, and place in the standard jazz repertoire. Appropriate historical sections of the selected texts were reviewed and coded using predetermined rubrics. Data were then aggregated into categories and then analyzed according to the character assigned to the key jazz personalities noted in the text as well as the comparative standing afforded each personality. ^ The results of this study demonstrate that particular key African-American jazz artists and composers occupy a significant place in these texts while other significant individuals representing other ethnic groups are consistently overlooked. This finding suggests that while America and the world celebrates the quality of the product of American jazz as great musically and significant socially, many ethnic contributors are not mentioned with the result being a less than complete picture of the evolution of this American art form. ^

Next generation high density three-dimensional magnetic recording systems

This work is the first work using patterned soft underlayers in multilevel three-dimensional vertical magnetic data storage systems. The motivation stems from an exponentially growing information stockpile, and a corresponding need for more efficient storage devices with higher density. The world information stockpile currently exceeds 150EB (ExaByte=1x1018Bytes); most of which is in analog form. Among the storage technologies (semiconductor, optical and magnetic), magnetic hard disk drives are posed to occupy a big role in personal, network as well as corporate storage. However; this mode suffers from a limit known as the Superparamagnetic limit; which limits achievable areal density due to fundamental quantum mechanical stability requirements. There are many viable techniques considered to defer superparamagnetism into the 100's of Gbit/in2 such as: patterned media, Heat-Assisted Magnetic Recording (HAMR), Self Organized Magnetic Arrays (SOMA), antiferromagnetically coupled structures (AFC), and perpendicular magnetic recording. Nonetheless, these techniques utilize a single magnetic layer; and can thusly be viewed as two-dimensional in nature. In this work a novel three-dimensional vertical magnetic recording approach is proposed. This approach utilizes the entire thickness of a magnetic multilayer structure to store information; with potential areal density well into the Tbit/in2 regime. ^ There are several possible implementations for 3D magnetic recording; each presenting its own set of requirements, merits and challenges. The issues and considerations pertaining to the development of such systems will be examined, and analyzed using empirical and numerical analysis techniques. Two novel key approaches are proposed and developed: (1) Patterned soft underlayer (SUL) which allows for enhanced recording of thicker media, (2) A combinatorial approach for 3D media development that facilitates concurrent investigation of various film parameters on a predefined performance metric. A case study is presented using combinatorial overcoats of Tantalum and Zirconium Oxides for corrosion protection in magnetic media. ^ Feasibility of 3D recording is demonstrated, and an emphasis on 3D media development is emphasized as a key prerequisite. Patterned SUL shows significant enhancement over conventional "un-patterned" SUL, and shows that geometry can be used as a design tool to achieve favorable field distribution where magnetic storage and magnetic phenomena are involved. ^

Ecophysiology and biomechanics of Equisetum giganteum in South America

Equisetum giganteum L., a giant horsetail, is one of the largest living members of an ancient group of non-flowering plants with a history extending back 377 million years. Its hollow upright stems grow to over 5 m in height. Equisetum giganteum occupies a wide range of habitats in southern South America. Colonies of this horsetail occupy large areas of the Atacama river valleys, including those with sufficiently high groundwater salinity to significantly reduce floristic diversity. The purpose of this research was to study the ecophysiological and biomechanical properties that allow E. giganteum to successfully colonize a range of habitats, varying in salinity and exposure. Stem ecophysiological behavior was measured via steady state porometry (stomatal conductance), thermocouple psychrometry (water potential), chlorophyll fluorescence, and ion specific electrodes (xylem fluid solutes). Stem biomechanical properties were measured via a 3-point bending apparatus and cross sectional imaging. Equisetum giganteum stems exhibit mechanical characteristics of semi-self-supporting plants, requiring mutual support or support of other vegetation when they grow tall. The mean elastic moduli (4.3 Chile, 4.0 Argentina) of E. giganteum in South America is by far the largest measured in any living horsetail. Stomatal behavior of E. giganteum is consistent with that of typical C3 vascular plants, although absolute values of maximum late morning stomatal conductance are very low in comparison to typical plants from mesic habitats. The internode stomata exhibit strong light response. However, the environmental sensitivity of stomatal conductance appeared less in young developing stems, possibly due to higher cuticular conductance. Exclusion of sodium (Na) and preferential accumulation of potassium (K) at the root level appears to be the key mechanism of salinity tolerance in E. giganteum. Overall stomatal conductance and chlorophyll fluorescence were little affected by salinity, ranging from very low levels up to half strength seawater. This suggests a high degree of salinity stress tolerance. The capacity of E. giganteum to adapt to a wide variety of environments in southern South America has allowed it to thrive despite tremendous environmental changes during their long tenure on Earth.

Tracking rates of ecotone migration due to salt-water encroachment using fossil mollusks in coastal South Florida

We determined the rate of migration of coastal vegetation zones in response to salt-water encroachment through paleoecological analysis of mollusks in 36 sediment cores taken along transects perpendicular to the coast in a 5.5 km2 band of coastal wetlands in southeast Florida. Five vegetation zones, separated by distinct ecotones, included freshwater swamp forest, freshwater marsh, and dwarf, transitional and fringing mangrove forest. Vegetation composition, soil depth and organic matter content, porewater salinity and the contemporary mollusk community were determined at 226 sites to establish the salinity preferences of the mollusk fauna. Calibration models allowed accurate inference of salinity and vegetation type from fossil mollusk assemblages in chronologically calibrated sediments. Most sediments were shallow (20–130 cm) permitting coarse-scale temporal inferences for three zones: an upper peat layer (zone 1) representing the last 30–70 years, a mixed peat-marl layer (zone 2) representing the previous ca. 150–250 years and a basal section (zone 3) of ranging from 310 to 2990 YBP. Modern peat accretion rates averaged 3.1 mm yr)1 while subsurface marl accreted more slowly at 0.8 mm yr)1. Salinity and vegetation type for zone 1 show a steep gradient with freshwater communities being confined west of a north–south drainage canal constructed in 1960. Inferences for zone 2 (pre-drainage) suggest that freshwater marshes and associated forest units covered 90% of the area, with mangrove forests only present along the peripheral coastline. During the entire pre-drainage history, salinity in the entire area was maintained below a mean of 2 ppt and only small pockets of mangroves were present; currently, salinity averages 13.2 ppt and mangroves occupy 95% of the wetland. Over 3 km2 of freshwater wetland vegetation type have been lost from this basin due to salt-water encroachment, estimated from the mollusk-inferred migration rate of freshwater vegetation of 3.1 m yr)1 for the last 70 years (compared to 0.14 m yr)1 for the pre-drainage period). This rapid rate of encroachment is driven by sea-level rise and freshwater diversion. Plans for rehydrating these basins with freshwater will require high-magnitude re-diversion to counteract locally high rates of sea-level rise.

An automated method for the determination of electroreception thresholds in weakly electric fish

Weakly electric fish produce a dual function electric signal that makes them ideal models for the study of sensory computation and signal evolution. This signal, the electric organ discharge (EOD), is used for communication and navigation. In some families of gymnotiform electric fish, the EOD is a dynamic signal that increases in amplitude during social interactions. Amplitude increase could facilitate communication by increasing the likelihood of being sensed by others or by impressing prospective mates or rivals. Conversely, by increasing its signal amplitude a fish might increase its sensitivity to objects by lowering its electrolocation detection threshold. To determine how EOD modulations elicited in the social context affect electrolocation, I developed an automated and fast method for measuring electroreception thresholds using a classical conditioning paradigm. This method employs a moving shelter tube, which these fish occupy at rest during the day, paired with an electrical stimulus. A custom built and programmed robotic system presents the electrical stimulus to the fish, slides the shelter tube requiring them to follow, and records video of their movements. I trained the electric fish of the genus Sternopygus was trained to respond to a resistive stimulus on this apparatus in 2 days. The motion detection algorithm correctly identifies the responses 91% of the time, with a false positive rate of only 4%. This system allows for a large number of trials, decreasing the amount of time needed to determine behavioral electroreception thresholds. This novel method enables the evaluation the evolutionary interplay between two conflicting sensory forces, social communication and navigation.

A Proposed Hospitality Curriculum for Two-Year Colleges in Florida

The expansion of the hotel industry and its related areas necessitates new educational training for those who will occupy positions of responsibility. Two-year colleges provide one possibility for this training. The authors propose a common foundation for all such programs in Florida.

Ballots for Equality: An Approach to the Radical Tradition in U.S. Electoral Politics

Posing radical challenges to structural inequality is the defining quality of the Left. What role electoral politics might play in such processes is a dilemma of radical politics, the contours of which vary by historical and national contexts. For the U.S. Left there is a distinctive aspect of the dilemma directly related to the failure of a "Left" party of even the most moderate social democratic type to take root, creating a seemingly never ending debate over the value if any of "third party" progressive organizing. This debate is current, as illustrated by three divergent approaches; independent left electoral politics (Socialist Alternative), organizing within the less conservative of the dominant parties (Progressive Democrats of America), and a social movement focus outside the electoral process (Occupy Movement). The present day examples of alternative Left strategies noted here in passing are but three of many such specific organizational options for progressive politics. This article does not seek to advocate for any one of these options to the exclusion of the others but rather seeks to provide historical perspective.

Entre veados, carneiros e formigas: conflito pela posse de terra na ribeira do Ceará-Mirim, e concepções de mentalidade possessória, 1725-1761

Shaping the Luso-Brazilian space in Portuguese America was through constant conflicts between different individuals and institutions. Regarding to land ownership, such conflicts were aggravated, depending on the individuals involved and their context. The captaincy of Rio Grande, there is conflict over land ownership Cidade dos Veados and Olho d' Água Azul and its stakeholders: priests of the Society of missionaries of the village Guajiru; indian mission Guajiru; and members of Carneiro da Cunha family. In 1725, the jesuit mission Guajiru requested a league of land at a place called Cidade dos Veados for the indians of his mission claiming that the land that the mission had was not sufficient for the subsistence of the same. In 1727, priest requested another league of land in place Olho d'Água Azul, stating that the mission had more than 192 couples. Both lands were properly required for the mission guajiru. however, in 1760, with the changes imposed by the indian directorate ombudsman responsible for investigating indigenous possessions realized that the indians did not occupy the two lands requested in the 1720s , due to the fact João Carneiro da Cunha has taken possession of the same. As a result, the impasse over land are ligth. This conflict over land ownership Cidade dos Veados and Olho d'Água Azul, we intend to highlight in particular the motivations and mindsets about possessory property of each party involved. We seek to understand the motivations of each group involved allowed the use of specific strategies and set out to try to take possession of the lands of the Cidade dos Veados e Olho d'Água Azul

A colocação de pronomes clíticos em sentenças infinitivas preposicionadas na escrita brasileira dos séculos XIX e XX

In this work we present the description and analysis of the clitics collocation patterns in prepositional infinitive sentences within the Brazilian writing in the centuries XIX and XX. The corpus in analysis is comprised of letters of newspaper readers and newspaper writers, as well as of advertisements (ads) taken from Brazilian newspapers from different regions / states – Rio de Janeiro, Bahia, Ceará and Pernambuco – and written in the Centuries XIX and XX. They belong to the common minimum corpus of the project named Projeto para a História do Português Brasileiro (PHPB or Project to the History of the Brazilian Portuguese, in English). Its analysis is based on theoreticalmethodological postulates of the Theory of Variation and Change (WEINREICH; LABOV; HERZOG, 1968[2006]; LABOV, 1972[2008]); on the Theory of Principles and Parameters (CHOMSKY, 1981, 1986) and on the model of Grammar Competition (KROCH, 1989; 2001). By trying to articulate those presuppositions from both the theories we present a proposition of theoretical interface between the Variation Theory and the Grammar one. Concerning the empirical results achieved by means of this research, we could figure that, in the context in which there were prepositional infinitive sentences, the most significant independent variable to the occurrence of the proclisis is the type of preposition that comes before the verb in the infinitive. Before that, we found out that there are prepositions which strongly direct the proclisis, as it is the case of the prepositions in Portuguese sem, por, de and para, with all of them presenting Relative Weights over 0,52. Another important result is the one attested in the data referring the state of Rio de Janeiro (RJ). This state is the only one of the sample which is located in the Southeastern region and also presents itself as the main proclisis conditioner amongst the localities pertaining to the sample. In order to explain those results, we raised the hypothesis that the proclisis implementation may be more advanced in the Southeastern than in the Northeastern Brazil, however that hypothesis must be confirmed or refuted in future works. We also present, in this work, a theoretical explanation about the clitics colocation in prepositional infinitive sentences within the Brazilian writing in the XIX and XX centuries. The theoretical explanation we found to interpret the achieved results associates Magro’s proposition (2005), regarding the existence of prepositions occupying the nucleus PP and the existence of prepositions which can play the role of a completer and occupy the nucleus CP, according to Galves (2000; 2001), regarding the existent relation between the clitic colocation and the association of traits-phi to the functional categories COMP, Tense and Person. Our proposition is that the occurrence of prepositions which occupy the nucleus CP causes changes in the values attributed to the traits-phi and to the strong Vtraits in the functional categories COMP, Tense and Person. Thus, we defend that proclisis in Brazilian Portuguese (BP) is derived from the movement of the verb to the functional category tense in which there is the association of traits +V and traits +AGR, what legitimates the proclisis according to Galves´s proposition (2000; 2001).

“Acham que brotamos das fontes dessa cidade?”: uma etnografia sobre o cotidiano de sobrevivência de pessoas em situação de rua em Nata/RN

Through participant observation, held in the administrative region east of Natal / RN, this research aimed to understand about the daily life of men and women living on the streets in the city. How they relate to the space where they live? In this relationship, which uses and survival strategies triggered by this social segment? These were some of the questions that guided this research, in order to highlight the specificities of this way of life and the possible consequences that such a situation could reverberate. In this sense, there was an effort to keep up with people on the streets, their itineraries and seize their narratives. Along the search path - which took place intermittently between the years 2011-2015 - attended spaces of occupation and traffic of this population group in the street, as well as insert me and got involved in events, forums, seminars, meetings and subject of joints on the streets as a political movement (MNPR / RN). They are considered in this study as people on the street to those who occupy the street as their main space of survival and ordering of daily life: in the streets sleep, feed themselves, meet the physiological and hygienic needs, and is where draw sustenance. The street is taken in this research in its broadest sense, including all possible places relatively protected from the cold, rain and exposure to violence, thus includes both open and public spaces: as squares and parks; but also closed and private places: hostels, abandoned warehouses, prisons, etc. It was observed that in none of these spaces guys on the street are established in a fixed manner, in contrast, they experience the roaming, which in part is due to urban systems - which tends to stigmatize them and delete them places - and the very need to survive, because while living in the street differentiated practices are triggered, and these differ from the dominant mode of sedentary life.
