Analysis of spring break-up and its effects on a biomass feedstock supply chain in northern Michigan

Demand for bio-fuels is expected to increase, due to rising prices of fossil fuels and concerns over greenhouse gas emissions and energy security. The overall cost of biomass energy generation is primarily related to biomass harvesting activity, transportation, and storage. With a commercial-scale cellulosic ethanol processing facility in Kinross Township of Chippewa County, Michigan about to be built, models including a simulation model and an optimization model have been developed to provide decision support for the facility. Both models track cost, emissions and energy consumption. While the optimization model provides guidance for a long-term strategic plan, the simulation model aims to present detailed output for specified operational scenarios over an annual period. Most importantly, the simulation model considers the uncertainty of spring break-up timing, i.e., seasonal road restrictions. Spring break-up timing is important because it will impact the feasibility of harvesting activity and the time duration of transportation restrictions, which significantly changes the availability of feedstock for the processing facility. This thesis focuses on the statistical model of spring break-up used in the simulation model. Spring break-up timing depends on various factors, including temperature, road conditions and soil type, as well as individual decision making processes at the county level. The spring break-up model, based on the historical spring break-up data from 27 counties over the period of 2002-2010, starts by specifying the probability distribution of a particular county’s spring break-up start day and end day, and then relates the spring break-up timing of the other counties in the harvesting zone to the first county. In order to estimate the dependence relationship between counties, regression analyses, including standard linear regression and reduced major axis regression, are conducted. Using realizations (scenarios) of spring break-up generated by the statistical spring breakup model, the simulation model is able to probabilistically evaluate different harvesting and transportation plans to help the bio-fuel facility select the most effective strategy. For early spring break-up, which usually indicates a longer than average break-up period, more log storage is required, total cost increases, and the probability of plant closure increases. The risk of plant closure may be partially offset through increased use of rail transportation, which is not subject to spring break-up restrictions. However, rail availability and rail yard storage may then become limiting factors in the supply chain. Rail use will impact total cost, energy consumption, system-wide CO2 emissions, and the reliability of providing feedstock to the bio-fuel processing facility.

Interculturalidad e internacionalización en la Universidad Nacional de Cuyo

En esta investigación se articulan los antecedentes bibliográficos y diversos estudios sobre internacionalización de la educación superior y movilidad estudiantil, el enfoque latinoamericano de la interculturalidad y la perspectiva teórico-metodológica de Pierre Bourdieu. Existen múltiples y relevantes contribuciones que han analizado el fenómeno de la interculturalidad desde América Latina. Considerando que la educación superior latinoamericana viene atravesando un proceso constante y creciente de internacionalización, es un espacio en el que las reflexiones acerca de la interculturalidad han encontrado poco eco. De esta manera, resulta de especial interés plantear desde un ámbito universitario público, que promueve cada vez más su vinculación internacional, qué signo ha tenido la política de internacionalización universitaria en el período 2002-2010 y qué desafíos presenta desde la perspectiva de la interculturalidad.

Mass balance and acceleration of the Greenland ice sheet

Within the last decade, the Greenland ice sheet (GrIS) and its surroundings have experienced record high surface temperatures (Mote, 2007, doi:10.1029/2007GL031976; Box et al., 2010), ice sheet melt extent (Fettweis et al., 2011, doi:10.5194/tc-5-359-2011) and record-low summer sea-ice extent (Nghiem et al., 2007, doi:10.1029/2007GL031138). Using three independent data sets, we derive, for the first time, consistent ice-mass trends and temporal variations within seven major drainage basins from gravity fields from the Gravity Recovery and Climate Experiment (GRACE; Tapley et al., 2004, doi:10.1029/2004GL019920), surface-ice velocities from Inteferometric Synthetic Aperture Radar (InSAR; Rignot and Kanagaratnam, 2006, doi:10.1126/science.1121381) together with output of the regional atmospheric climate modelling (RACMO2/ GR; Ettema et al., 2009, doi:10.1029/2009GL038110), and surface-elevation changes from the Ice, cloud and land elevation satellite (ICESat; Sorensen et al., 2011, doi:10.5194/tc-5-173-2011). We show that changing ice discharge (D), surface melting and subsequent run-off (M/R) and precipitation (P) all contribute, in a complex and regionally variable interplay, to the increasingly negative mass balance of the GrIS observed within the last decade. Interannual variability in P along the northwest and west coasts of the GrIS largely explains the apparent regional mass loss increase during 2002-2010, and obscures increasing M/R and D since the 1990s. In winter 2002/2003 and 2008/2009, accumulation anomalies in the east and southeast temporarily outweighed the losses by M/R and D that prevailed during 2003-2008, and after summer 2010. Overall, for all basins of the GrIS, the decadal variability of anomalies in P, M/R and D between 1958 and 2010 (w.r.t. 1961-1990) was significantly exceeded by the regional trends observed during the GRACE period (2002-2011).

O COORDENADOR PEDAGÓGICO E A FORMAÇÃO CONTINUADA DOS PROFISSIONAIS DE CRECHE: POSSIBILIDADES E DESAFIOS

O Plano Nacional de Educação (PNE) determina que 50% das crianças de 0 a 3 anos tenham vagas garantidas em Creches Públicas e a Lei do Piso n. 11.738/08 apresenta, em seu parágrafo quarto, que na composição da jornada de trabalho do professor observar-se-á um terço destinado à formação. A determinação destas mudanças aumenta a preocupação e responsabilidade em qualificar a formação continuada nestas instituições, as quais ainda sentem o peso dos vários anos de negligência. Pela atualidade e importância temática, a presente abordagem investiga a trajetória formativa e profissional de educadores de Creche, com o objetivo de possibilitar a reflexão e a análise sobre as estratégias utilizadas na formação continuada, bem como um debate dialético entre as práticas e as teorias trazidas nos estudos e pesquisas. Através da metodologia da Pesquisa de Campo de Natureza Qualitativa, buscou-se, ao contatar profissionais de cinco creches do município de São Bernardo do Campo, investigar a seguinte questão: De que forma o Coordenador Pedagógico que atua em creche tem contribuído, ou não, com a formação de profissionais reflexivos, pesquisadores e autores da própria prática? No intuito de responder a questão, foram realizadas entrevistas com cinco Coordenadoras Pedagógicas (CPs), três Professoras e dois Auxiliares em Educação e, em vista de maiores subsídios necessários ao debate, também foram entrevistadas uma Coordenadora de um curso de Pedagogia, com a finalidade de ampliar os conhecimentos sobre o curso de Pedagogia na atualidade, e uma Gestora (Chefe de Região) de São Bernardo do Campo, a fim de entender o olhar que o município tem hoje para a Creche. É importante ressaltar que o foco das entrevistas foi o trabalho desenvolvido pelo CP e que o trabalho investigativo junto aos demais profissionais envolvidos auxiliam na busca e obtenção de respostas para os questionamentos que levaram à construção deste trabalho. Os referenciais teóricos, desenvolvidos através da metodologia da Pesquisa de Natureza Bibliográfica e Documental para a revisão da literatura disponível sobre o tema, estão ancorados em Almeida e Placco (2002; 2010; 2011) que observam o papel do CP sob diversos aspectos; Day (1999) que discute os desafios fundamentais a serem considerados na formação; Fullan e Hargreaves (2002) que apresentam questionamentos sobre as estratégias formativas; Nóvoa (2009) ao investigar sobre a formação permanente dos professores; Perrenoud e Thurler (2002) que destacam novos paradigmas na formação dos professores; Vasconcellos (2009) que observa as articulações necessárias ao trabalho do CP; Campos et al (2011) que mostram a qualidade da Educação Infantil no país, entre outros. A análise dos conteúdos das entrevistas realizadas indica que a formação continuada avança gradativamente e, este mérito é dado, em grande parte, à formação que os gestores vêm recebendo e às parcerias produtivas que se estabelecem no processo, porém, os estudos e pesquisas teóricas apontam que muito ainda precisa ser feito e sinalizam mudanças imprescindíveis e que sejam capazes de impulsionar a formação a sair do tradicionalismo, tornando-se mais voltada à reflexão e humanização.

The rise and fall of stand-alone social reporting in a multinational subsidiary in Bangladesh:a case study

Purpose -The main aim of this paper is to examine the underlying drivers for the development and subsequent discontinuation of stand-alone corporate social responsibility (CSR) reporting in a multinational subsidiary in Bangladesh. Design/Methodology/Approach - The research approach employed for this purpose is a case study using evidence from a series of in depth interviews conducted during the period 2002-2010. Interview data is supplemented by examining other sources of information including annual reports, stand-alone social reports and relevant newspaper articles during the study period. Findings - It appears that the stand-alone CSR reporting process was initiated to give the subsidiary a formal space in which to legitimise its activities in Bangladesh where both tobacco control regulation and a strong anti-tobacco movement were gaining momentum. At the start of the process in 2002 corporate interviewees were very receptive of this initiative and strongly believed that it would not be a one off exercise. However, in the face of subsequent significant national policy shifts concerning tobacco control, irreconcilable stakeholder demands and increasing criticism of the CSR activities of the organisation at home and abroad the process was brought to an abrupt end in 2009. Research Limitations/Implications - The paper has a number of implications for policy makers concerning the future prospects for stand-alone social/sustainability reporting as a means of enhancing organisational transparency and accountability. In addition the paper discusses a number of theoretical implications for the development of legitimacy theory. Originality/value - Using the lens of legitimacy the paper theorises the circumstances leading to the initiation and subsequent cessation of CSR reporting in the organisation concerned. As far as we know this is the first study which theorises and provides significant fieldwork based empirical evidence regarding the discontinuation of stand-alone social reporting by a multinational company operating in a developing country. Thus, it extends previous desk-based attempts at using legitimacy theory to explain a decrease (or discontinuity) in CSR disclosures by de Villiers and van Staden (2006) and Tilling and Tilt (2010).

A responsabilidade enunciativa na sentença judicial condenatória

The Textual Analysis of Discourse has its origin in Text Linguistics and it aims at studying the co(n)text meaning production based on the analysis of concrete texts by offering elements to the understanding of the text as a discourse practice throughout the plans or levels of linguistic analysis. In this perspective, we intend to investigate the enunciative responsibility phenomenon in the sentencing court judgment. To do so, we review the theoretical contributions of Textual Analysis of Discourse (ADAM, 2011) and the Enunciative Linguistics from various authors, among them, Rabatel (1998, 2003, 2004, 2005, 2008, 2009, 2010), Nølke (2001, 2005, 2009, 2013), Nølke, Fløttum and Norén (2004), Guentchéva (1994, 1996) and Guentchéva et al. (1994). In this direction, we investigate the enunciative responsibility through a range that comprises the phenomenon from four gradations, each one with a kind of point of view (PoV) and with links that may mark the assumption or the distance from the point of view. Regarding the legal approach of the thesis, our theoretical anchoring follows several authors, among them, Petri (1994), Soto (2001), Alvarez (2002), Alves (2003), Cornu (2005), Albi (2007), Bittar (2010), Asensio and Polanco (2011), López Samaniego (2006), López Montolío and Samaniego (2008), Montolío (2002, 2010, 2011, 2012, 2013), Sterling (2010), Prieto (2013), Lawrence and Rodrigues (2013) and Rodrigues, Passeggi and Silva Neto (2014). Our corpus is composed of 13 sentences from criminal cases arising from the district of Currais Novos-RN, completed in 2012. The results reveal how the judge, from various enunciative instances, builds the court decision, which allowed us to understand the configuration of (non) assumption of enunciative responsibility in the sentencing court judgment discourse genre. In conclusion, we perceive that the discourse units are envisaged or through the assumption, or the non assumption of PoV by the enunciative instances, what guides the producer organization argumentative text and his (her) communicative purposes. With that, the judge creates and/or modifies values and beliefs, induces and/or guides his (her) interlocutor by being able to demonstrate objectivity and/or preventing his (her) face through the mediated constructions or engage through the assumption of the enunciative responsibility of the propositional content of an utterance. In short, we reaffirm our belief that the (non) assumption of the enunciative responsibility configures as an argumentative mechanism strongly marked by the producer of the text with a view to their communicative purposes. The sentence, therefore, is constructed in this game of taking and/or not taking of statements according to argumentative orientation and the objectives of the text producer.

Sustentabilidade e gestão da pesca artesanal na costa do Semiárido Potiguar (RN), Brasil

T he socio - economy of the coastal municipalities of Rio Grande do Norte semiarid coast was analyzed th r ou g h by the actors, ant hropogenic implications, fishing environment and composition of its fish fauna, as well as the trend of product ion landed by the artisanal fleet with the aim of identifying the sustainability and management. In this study, were used participatory methodologies, monthly data of rainfall between September 2001 and December 2010; landings of the artisanal fleet during January 2001 to December 2010; and socioeconomic (IBGE, 2002/2010), (IDEMA, 2011/2012), (MPA, 2010; 2012), UNDP and MS (2013). Based on these data, we performed analysis of variance were performed using the method of Analytic Hierarchy Process (HAP) and s tatistical models of multiple regression and time series. It was identified that the occupation of the coastal and marine zone through salt industry, tourism, shrimp farming, oil and gas and wind energy reconfigured the environment and attracted new actors . Rainfall influenced the catches, of which 35% occur in the rainy season, 40% in the dry season and 25% independent. Production increased 55%, in the period analyzed , being landed in 31 ports spread over 11 municipalities, cap tured in environments mangrov e/ estuarine (23%), coastal (46%) and oceanic (31%). Despite market up 41 species, were commercialized in the region production concentrated in eight, mainly landed in Macau and Caiçara North, by vessels of small and medium - sized (motorized and sailboats) . Highlights included three species ( Hirundichthys affins , Coryphaena hippurus and Opisthonema oglinum ), which together accounted for 63.3% of the whole volume. It was found that the motorized vessels tripled in number while sailboats reduced by half. Landin gs by different types of vessels tend to increase over time, while the small sailboats vessels, decrease. The introduction of more new motorized vessels and sailboats also tend to increase production. The study concluded that GDP and HDI of coastal countie s increased however inequality persisted. The potential of artisanal fishing is in the stage “ unfavorable ” of development and the trend in fish production is to grow over time and with the entry of more vessels. However, it is urgent that the state actions to promote and enhance planning to restore fish stocks in a sustainable and profitable fisheries standards. Therefore, it is recommend the strategic use of natural resources in a sustainable development perspective.

Querido diário: a construção identitária de alunos da EJA em diários pessoais

This study aims to present analyses of our research, documentary type, which investigates the construction of cultural identities of the Youth and Adults Education (Educação de Jovens e Adultos – EJA), level III, in a public school in the city of Natal/RN, through personal diaries produced in the school environment. In a qualitative-interpretive approach, we anchor our identity studies (BAUMAN, 2001, 2005, 2006; HALL, 1987, 1997, 2011, 2012) that bring us the idea that identities are built and rebuilt by social relations that we do. To this end, we start from a conception of language that does not require pre-conceptions because they are based on the utterance itself. Therefore, we have analyzed the utterances produced by these students from the perspective of Bakhtin Circle (BAKHTIN, 1988, 1993, 1998, 2002, 2010, 2012), which deals with the discursive construction emerging from intersubjective processes of verbal interaction, in a dialogical relationship of the self to the other, by the otherness and the heteroglossia. Moreover, our study is also guided by the guidance on speech genres (BAKHTIN, 2010) and personal journal (LEJEUNE, 2008; MACHADO, 1998, 2009). We join to Applied Linguistics (MOITA LOPES, 2006, 2009) because we believe that this research focuses on a social practice in which language plays a central role and seeks to demonstrate how the speeches of the subject students of EJA, in personal journals, are building tools not only of their identities, but also knowledge and social life of the position that this subject student takes. We conclude this work in a perception of cultural identities that are built by the subject students of EJA, because the results suggest that the identities of these students are fluidly constructed by the representation that the student makes of his or her school, of being student of EJA and how he or she is a student of this educational modality. Thus, through our work, we plan to present another look about the identity or identities of a student of EJA, pointing an insight of this subject.

Home birth in Ireland 1993-1997: a review of community midwifery practice

To date little is known about the practices of domiciliary midwives and the outcomes of home birth in Ireland. The purpose of this review is to provide some background information on the situation for women seeking a home birth and to document the outcomes of home births in Ireland between 1993 -1997. Design: Descriptive analysis of prospective data collected from domiciliary midwives regarding women who requested a home birth between 1993 and 1997. Participants: The questionnaire was distributed to 15 domiciliary midwives; this included all the domiciliary midwives known to the authors to be practising in Ireland at that time. Findings: During this period, 585 women planned to give birth in their home with the assistance of midwives, 500 women achieved this. The spontaneous vaginal delivery rate for women who commenced their labour at home was 96.9% (n = 554). These women gave birth without medications or other interventions. 544 (93%) of the women breastfed their babies and 538 (92%) were still breastfeeding at 6 weeks. This is the first review of domiciliary midwifery practice in Ireland in recent years. They obtained data from 11 independent midwives on 585 women who planned home births. Findings showed high rates of spontaneous vaginal delivery and breastfeeding. There were 500 babies born at home with three perinatal deaths, including one undiagnosed breech delivery, one infant with abnormal lungs on post-mortem and one infant with Potter's Syndrome who was stillborn.

Multilevel Governance and Accountability: Does Decentralization Promote Good Governance?

Today, the trend towards decentralization is far-reaching. Proponents of decentralization have argued that decentralization promotes responsive and accountable local government by shortening the distance between local representatives and their constituency. However, in this paper, I focus on the countervailing effect of decentralization on the accountability mechanism, arguing that decentralization, which increases the number of actors eligible for policy making and implementation in governance as a whole, may blur lines of responsibility, thus weakening citizens’ ability to sanction government in election. By using the ordinary least squares (OLS) interaction model based on historical panel data for 78 countries in the 2002 – 2010 period, I test the hypothesis that as the number of government tiers increases, there will be a negative interaction between the number of government tiers and decentralization policies. The regression results show empirical evidence that decentralization policies, having a positive impact on governance under a relatively simple form of multilevel governance, have no more statistically significant effects as the complexity of government structure exceeds a certain degree. In particular, this paper found that the presence of intergovernmental meeting with legally binding authority have a negative impact on governance when the complexity of government structure reaches to the highest level.

Eosinophilia is a favourable prognostic marker in oral squamous cell carcinoma

Suusyöpä on yleisin pään ja kaulan alueen pahanlaatuisista kasvaimista. Niistä yli 90 % on levyepiteelikarsinoomia. Koska suusyöpäpotilaan viisivuotisennuste on vain noin 50 %, on jatkuva tarve löytää keinoja ennustamaan potilaan selviytymistä ja ohjaamaan hoitoa. Suun levyepiteelikarsinooman ympäristössä havaitaan säännöllisesti eosinofiilejä. Eosinofiili on ihmisen immuunijärjestelmän erikoistunut solu, joiden määrä lisääntyy sekä tulehdusreaktioissa että syöpien läheisyydessä. Toistaiseksi ei tiedetä, miten eosinofiilit liittyvät suun levyepiteelikarsinoomaan, mutta oletuksena on, että suusyöpään liittyvällä eosinofilialla, TATE (tumor-associated tissue eosinophilia), voisi olla vaikutusta suun levyepiteelikarsinoomapotilaan ennusteeseen. Tämän tutkimuksen tarkoituksena oli selvittää TATE:n ilmenemistä ja vaikutusta potilaan ennusteeseen suun levyepiteelikarsinoomassa. Lisäksi tutkimus käsittelee potilaan ennusteen kannalta optimaalista eosinofiilimäärän raja-arvoa, jota voitaisiin käyttää patologin työkaluna ennusteen arvioinnissa. Tutkimusaineisto koostui Turun yliopiston Suupatologian laitoksella vuosina 2002-2010 tutkituista 122 suuontelon ja huulen limakalvokoepalasta, jotka oli otettu diagnostisia tarkoituksia varten 99 potilaalta. Tutkimuksen potilaista 44 oli naisia ja 55 miehiä, ja heidän keski-ikänsä oli 65,3 vuotta. Seuranta-aika oli keskimäärin 40,7 kk. Kaksi tutkijaa analysoivat hematoksyliini-eosiinilla värjätyt näytteet suurentamalla ne 400-kertaisiksi valomikroskoopilla. Eosinofiilien määrä laskettiin yhteensä kuudelta edustavimmalta syövän ja strooman alueelta. TATE:n suhde potilaan kliinispatologisiin piirteisiin ja selviytymiseen selvitettiin Turun yliopistollisen keskussairaalan potilastiedoistoista ja analysoitiin tilastollisesti käyttämällä Fischerin testiä. Työllä oli Varsinais-Suomen sairaanhoitopiirin eettisen toimikunnan lupa (nro T10/2011, päätös O31/11). Levyepiteelikarsinooman kliininen kuva vaihteli haavaisen muutoksen ollessa yleisin. Yleisin sijainti levyepiteelikarsinoomalle oli kieli. TATE:a löydettiin 61,5 %:sta (78/122) levyepiteelikarsinoomanäytteitä. Mikäli TATE:a ei löydetty tai sen määrä oli korkea, oli potilaan selviytyminen tilastollisesti merkitsevästi parempi kuin potilailla, joilla TATE oli matala. Lisäanalyyseissä havaittiin, että potilaan ennuste oli tilastollisesti merkitsevästi huonompi, mikäli TATE:n raja-arvo oli vähemmän kuin neljä eosinofiiliä per tutkittu mikroskooppinäkymä (HPF). TATE on täten merkki suun levyepiteelikarsinoomapotilaan paremmasta ennusteesta erityisesti, kun havaitaan enemmän kuin neljä eosinofiiliä/HPF. Tutkimustulosten varmistamiseksi tarvitaan kuitenkin jatkossa laajempia tutkimuksia.

Empirical validation of CAPM

This paper pretends to show empirical evidence of the CAPM model of Sharpe-Lintner (1964) for Colombia from 2003 to 2010, whose validation is carried out using the method of Black, Jensen and Scholes (1972) but introducing certain methodological econometric type changes associated to the requirements imposed by the used sample -- Specifically, we found no empirical evidence to reject the CAPM for the Colombian economyin the period under analysis

EL ESCENARIO SUBNACIONAL EN TRANSFORMACIÓN: LAS REFORMAS INSTITUCIONALES Y SU IMPACTO EN LA CONFIGURACION DEL MAPA POLITICO LOCAL EN URUGUAY

En un país fuertemente centralizado, donde los cambios institucionales tienden a ser graduales, la reforma constitucional de 1996 y más recientemente la aprobación de la Ley de Descentralización política y participación ciudadana en el 2010, constituyen dos hitos significativos que revalorizaron la política subnacional en Uruguay. Este artículo analiza los resultados de las elecciones de mayo de 2015, tanto a nivel departamental como municipal en perspectiva comparada, con el objetivo de mostrar la evolución del mapa político local y la relevancia que han adquirido las elecciones subnacionales en la política del país. A su vez, también se plantean ciertos desafíos que conlleva esta nueva configuración de la política local, centrándose en la importancia que han adquirido los actores políticos locales
