Green teams: Understanding their roles in the environmental management of companies located in Brazil

Green teams are frequently considered in the state-of-the-art literature as an essential factor for companies aiming to implement and improve environmental management approaches and practices. However, most of the available literature on green teams is conceptual and theoretical by nature. Therefore, the main purpose of this article is to evaluate the main characteristics of green teams in Brazilian companies and to analyse the relationships between green teams and the maturity level of environmental management in those companies. Based on a conceptual background on corporate environmental management and green teams, a research was done in two complementary phases: a survey of 94 companies with ISO 14001 certification; and a multiple case study of four industrial companies. Survey results suggest that 82% of the studied companies have cross-functional green teams, i.e. involving various companies' departments; and 65% have functional green teams, i.e. individual department teams. The results of the case study suggest that the use of green teams is an instrument to the greening of companies with ISO 14001 in Brazil. The company with the most proactive and advanced environmental management is the same company which uses green teams more intensely. Green teams are especially necessary for implementing more technical environmental management practices, e.g. Life Cycle Assessment. Since this is one of the first studies analysing green teams, the results presented can be useful for companies and public policies aiming to implementation of environmental initiatives. © 2012 Elsevier Ltd.

Environmental management in ethanol and sugarcane plants in Brazil

There has been much discussion on the importance of Brazilian ethanol in promoting a more sustainable society. However, there is a lack of analysis of whether sugarcane plants/factories that produce this ethanol are environmentally suitable. Thus, the objective of this study was to analyse stages of environmental management at four Brazilian ethanol-producing plants, examining the management practices adopted and the factors behind this adoption. The results indicate that (1) only one of the four plants is in the environmentally proactive stage; (2) all plants are adopting operational and organisational environmental management practices; (3) all plants have problems in communicating environmental management practices; and (4) the plant with the most advanced environmental management makes intense use of communication practices and is strongly oriented towards a more environmentally aware international market. This paper is an attempt to explain the complex relationship between the evolution of environmental management, environmental practices and motivation using a framework. The implications for society, plant directors and scholars are described, as well as the study's limitations.

An object-oriented neural network approach to short-term traffic forecasting

This paper discusses an object-oriented neural network model that was developed for predicting short-term traffic conditions on a section of the Pacific Highway between Brisbane and the Gold Coast in Queensland, Australia. The feasibility of this approach is demonstrated through a time-lag recurrent network (TLRN) which was developed for predicting speed data up to 15 minutes into the future. The results obtained indicate that the TLRN is capable of predicting speed up to 5 minutes into the future with a high degree of accuracy (90-94%). Similar models, which were developed for predicting freeway travel times on the same facility, were successful in predicting travel times up to 15 minutes into the future with a similar degree of accuracy (93-95%). These results represent substantial improvements on conventional model performance and clearly demonstrate the feasibility of using the object-oriented approach for short-term traffic prediction.

Are supplier selection criteria going green? Case studies of companies in Brazil

Purpose - The purpose of this paper is to verify if Brazilian companies are adopting environmental requirements in the supplier selection process. Further, this paper intends to analyze whether there is a relation between the level of environmental management maturity and the inclusion of environmental criteria in the companies` selection of suppliers. Design/methodology/approach - A review of mainstream literature on environmental management, traditional criteria in the supplier selection process and the incorporation of environmental requirements in this context. The empirical study`s strategy is based on five Brazilian case studies with industrial companies. Face-to-face interviews and informal conversations are to be held, explanations made by e-mail with representatives from the purchasing, environmental management, logistics and other areas, and observation and the collection of company documents are also employed. Findings - Based on the cases, it is concluded that companies still use traditional criteria to select suppliers, such as quality and cost, and do not adopt environmental requirements in the supplier selection process in a uniform manner. Evidence found shows that the level of environmental management maturity influences the depth with which companies adopt environmental criteria when selecting suppliers. Thus, a company with more advanced environmental management adopts more formal procedures for selecting environmentally appropriate suppliers than others. Originality/value - This is the first known study to verify if Brazilian companies are adopting environmental requirements in the supplier selection process.

Mapping the Pasture Steppe in Bayankhongor, Mongolia: comparison of classification methods, using Landsat-8 and geophysical data

Grasslands in semi-arid regions, like Mongolian steppes, are facing desertification and degradation processes, due to climate change. Mongolia’s main economic activity consists on an extensive livestock production and, therefore, it is a concerning matter for the decision makers. Remote sensing and Geographic Information Systems provide the tools for advanced ecosystem management and have been widely used for monitoring and management of pasture resources. This study investigates which is the higher thematic detail that is possible to achieve through remote sensing, to map the steppe vegetation, using medium resolution earth observation imagery in three districts (soums) of Mongolia: Dzag, Buutsagaan and Khureemaral. After considering different thematic levels of detail for classifying the steppe vegetation, the existent pasture types within the steppe were chosen to be mapped. In order to investigate which combination of data sets yields the best results and which classification algorithm is more suitable for incorporating these data sets, a comparison between different classification methods were tested for the study area. Sixteen classifications were performed using different combinations of estimators, Landsat-8 (spectral bands and Landsat-8 NDVI-derived) and geophysical data (elevation, mean annual precipitation and mean annual temperature) using two classification algorithms, maximum likelihood and decision tree. Results showed that the best performing model was the one that incorporated Landsat-8 bands with mean annual precipitation and mean annual temperature (Model 13), using the decision tree. For maximum likelihood, the model that incorporated Landsat-8 bands with mean annual precipitation (Model 5) and the one that incorporated Landsat-8 bands with mean annual precipitation and mean annual temperature (Model 13), achieved the higher accuracies for this algorithm. The decision tree models consistently outperformed the maximum likelihood ones.

The EuroSIDA study: Regional differences in the HIV-1 epidemic and treatment response to antiretroviral therapy among HIV-infected patients across Europe--a review of published results.

EuroSIDA is a pan-European observational study that follows 14,265 HIV-infected patients from 31 European countries, Israel and Argentina, of which 2,560 are patients from eastern Europe (EE). The study group has performed several analyses addressing regional differences in the HIV-epidemic across Europe, where all countries were divided into five regions: south, west central, north, east central Europe and EE. Significant regional differences in patients' characteristics and pattern of AIDS diagnoses were documented. More patients from EE were diagnosed with tuberculosis compared to other regions. Significantly fewer HIV-infected patients in EE, who fulfilled the criteria for starting combination antiretroviral therapy (cART), actually received cART as compared with other regions of Europe. Those, receiving cART in EE had a lower initial virologic response rate irrespectively of the regimen used, although it has improved within years. Besides, treatment failure was more common in this region. Thus, improvements in the clinical management of HIV patients in EE are urgently needed. Strategies include creating scientific collaborations for HIV clinicians as well as teaching clinicians about the most advanced HIV management at clinically oriented courses held in eastern Europe.

Prosessinostureita valmistavan liiketoimintayksikön arvoverkoston kustannusrakenne

Työn tarkoituksena on tutkia prosessinosturiliiketoiminnan rajatun arvoketjun ja - verkoston kustannuksia. Tavoitteena on selvittää valittujen vaihtoehtoisten valmistuspaikkojen toimintojen pohjalta yleinen arvoketju kustannuskertymineen. Lisäksi tavoitteena on kehittää taulukkolaskentaohjelmistoon perustuva laskentamalli tai perustyökalu kustannusten kasautumisen arviointiin. Edelleen pyrkimyksenä on löytää rakennetusta mallin avulla kehitys- ja jatkotoimenpiteiden kohteita. Työssä perehdytään aluksi arvoketju -viitekehykseen ja niihin seikkoihin joista se muodostuu kirjallisuudesta löytyvän tiedon pohjalta. Arvoketjuajattelu on yksinkertaisimmillaan yrityksen toimintojen tarkastelua kilpailukyvyn ja -edun näkökulmasta. Liiketoiminnan kehittyminen verkostomaiseksi vaatii kuitenkin laajemman ¿ arvoverkosto - tarkastelunäkökulman. Toisaalta liiketoiminnan pidemmän aikavälin kilpailukyvyn suunnittelu edellyttää syvällisempää arvoketjujen ja toimintojen tarkastelua ja hallintaa, jolloin tarvitaan kehittyneempiä laskentatoimen menetelmiä ja kustannuslaskentajärjestelmiä. Tutkimuksen empiirisessä osiossa arvoketjuajattelua ja arvoverkostoviitekehystä sekä kustannuslaskentamenetelmiä sovelletaan käytännön tapauksiin. Tulokset osoittavat tutkimukseen valittujen neljän valmistuspaikan kustannuskertymän ja -rakenteen. Kustannuskertymältään alhaisimmaksi osoittautui tuotantolaitos Saudi-Arabiassa, kunloppuasiakkaan sijainti on Qatarissa. Puolalainen tehdas osoittautui puolestaankilpailukykyisimmäksi, kun nosturin toimitusosoite on Italian pohjoisosaan. Tulosten perusteella kustannusrakenteiden suurimmat kustannuserät ovat kuljetus-, teräsrakenteen valmistus- ja suunnittelutoiminnot.

Taloushallinnon laskentajärjestelmien tuottaman tiedon kehitystarpeet, case: ammattikorkeakoulun maksullinen palvelutoiminta

Tutkimuksessa haetaan vastausta kysymykseen: millaista tietoa ammattikorkeakoulun taloushallinnon laskentajärjestelmistä pitäisi saada, jotta se vastaisi tiedon tarvitsijoiden tarpeisiin, sekä ammattikorkeakoulun sisällä että organisaation sidosryhmiin nähden, mahdollisimman tarkoituksenmukaisesti ja tehokkaasti? Tavoitteina on selvittää taloushallinnon laskentajärjestelmien kehitystarpeet maksullisen palvelutoiminnan osalta ja vertailla kolmen eri ammattikorkeakoulun välillä taloushallinnon laskentajärjestelmistä saatavaa tietoa tuoden esille parhaat käytännöt ja tiedon-tuottamistavat. Tutkimus on rajattu koskemaan maksullista palvelutoimintaa ja tutkittavaa ilmiötä käsitellään ammattikorkeakoulun sisällä. Näkökulmina ovat johtajan ja päätöksentekijän, kehittäjän ja taloushallinto-osaston näkökulmat. Tutkimus on teemahaastatteluin toteutettava kvalita-tiivinen case-tutkimus, jonka lopputulemana syntyy 'Taloushallinnon raportoinnin johdonmukainen ja aktiivinen kehittäminen' -toimintamalli. Tutkimuksen teoria perustuu pääosin laskentatoimesta (strateginen, johdon ja rahoituksen laskentatoimi sekä laskentatoimi yrityksen informaatiojärjestelmänä), taloushallinnosta (mm.talousjohtaminen, taloushallinnon muuttuva rooli) sekä benchmarkingista kirjoitetulle kirjallisuudelle. Näistä muodostuu tutkimuksen teoreettinen viitekehys jaedelleen teemahaastattelu-lomake, joka toimii empiirisen osion tiedon hankinnan pohjana.

Konepajayrityksen kustannuslaskennan kehittäminen

Työn tavoitteena oli erään konepajan kustannuslaskennan kehittäminen. Kustannuslaskennan kehitystyö käsitti kustannuspaikkalaskennan järjestämisen ja suoritekohtaisen kustannuslaskennan uudistamisen. Työssä esitelty malli perustuu pääasiassa toimintolaskentaan ja lisäyslaskentaan. Kustannuslaskennan kehitystyöhön on vaikuttanut toimintaympäristön ja organisaation tietotarpeiden muuttuminen. Työhön liittyvä tutkimustiedon kerääminen on toteutettu toimintatutkimuksen osallistuvalla havainnoinnilla. Kehitetty malli on yksinkertainen ja helppo ylläpitää. Se on toteutettu niin, että sisäinen laskenta perustuu mahdollisimman paljon yrityksen ulkoiseen laskentatoimeen. Kehitetty malli on sikäli poikkeuksellinen, ettei siinä tehdä perinteisiä vyörytyksiä kustannuspaikkojen välillä. Kehitetty malli ei ole täyskatteellinen. Mallissa kiinnitetään erityinen huomio toimintotasolla kustannusten jakaantumiseen välittömiin ja välillisiin kustannuksiin. Työssä havaittiin tietojärjestelmien erittäin keskeinen rooli kustannuslaskentajärjestelmän kehitystyöprojektin vaikuttajana.
