La gestió del regadiu a Catalunya: plans, actors i reptes de futur

Irrigation has traditionally constituted one of the most characteristic and emblematic agricultural mosaics of the Mediterranean as a key factor of socio-economic dynamism of the territorial matrix. In recent years there has been an important scientific, intellectual and social environment mobilization around water uses and, in particular, around the main socio-economic use of resource: irrigation, which is undergoing an intense and accelerated transformation process. Thus, in parallel with the decline of traditional irrigation systems, located in areas with natural availability of water, fertile soil and appropriate topographic conditions, the socio-economic changes in the last decade have stimulated the appearance of new irrigated areas with environmental, social and economic disparate characteristics. As a result, the irrigation management model has been conditioned to respond to the new parameters of water scarcity and resource efficiency. In addition, policies and actors have evolved over time as a consequence of disparate priorities –and often conflicting– in terms of irrigation, making necessary the gear of different discourses. In this context, the Model of social commitment of irrigation proposed by the Institutional and Social Innovations in Irrigation Mediterranean Management (ISIIMM) can become a starting example

Análisis de viabilidad técnica-económica del parque eólico Altos de Peralta

RESUMEN La energia eolica se considera una forma indirecta de energia solar. Entre el 1 y 2% de la energia proveniente del sol se convierte en viento, debido al movimiento del aire ocasionado por el desigual calentamiento de la superficie terrestre. La energia cinetica del viento puede transformarse en energia util, tanto mecanica como electrica. La energia eolica, transformada en energia mecanica ha sido historicamente aprovechada, pero su uso para la generacion de energia electrica es mas reciente, en respuesta a la crisis del petroleo y a los impactos ambientales derivados del uso de combustibles. El objetivo principal de este trabajo es hacer un analisis de viabilidad desde un punto de vista tecnico y economico de un parque eolico situado en el municipio de Barasoain (Navarra). Desde el punto de vista tecnico se han estudiado los aspectos constructivos del parque considerando sus diferentes infraestructuras de obra civil y electrica asi como los niveles de recurso eolico. En el ambito economico y financiero se han analizado los aspectos y ratios mas relevantes que definen un proyecto de estas caracteristicas asi como el modelo de financiacion elegida basada en el Project- Finance. Entre las conclusiones mas destacadas de este proyecto cabe destacar la contribucion de la construccion del parque al desarrollo social y economico de la zona donde queda ubicado contribuyendo a la creacion de puestos de trabajo, tanto en la fase de construccion como de explotacion y una perfecta armonia con condicionantes medioambientales de la zona. El analisis tecnico realizado nos indica la viabilidad tecnica del parque tanto desde el punto de vista de recurso eolico como la idoneidad para poder evacuar la energia producida. Por otro lado, los resultados obtenidos cumplen perfectamente con los estandares requeridos por los financiadores de los parques y resultando ser muy atractivos para sus accionistas

"Vinci Cosmetics" Fabricación y comercialización de productos cosméticos

Contexto: La idea principal es la creación de una empresa para la fabricación y comercialización de productos cosméticos de alta gama. A pesar del contexto de crisis económica en el que estamos envueltos estos últimos años y del que no parece que acabamos de salir, el sector de la cosmética está resistiendo la situación de forma envidiable. De la crisis, como dicen los economistas, “se saldrá y se volverá, todo es cíclico” y viendo la fortaleza que éste sector está mostrando unido a la necesidad de que nuestra economía abandone sectores muy deteriorados y sin una previsión positiva de futuro, la cosmética se postula con un futuro prometedor dentro del contexto económico español y europeo. “Vinci Cosmetics” es el nombre inicialmente pensado para que la nueva compañía inicie su andadura. Nombre con tintes latinos de la lejana época del imperio romano como homenaje a la rica herencia histórica de la ciudad del autor del proyecto - Tarragona. La cultura por cuidarse y sentirse bien, muy arraigada en la mentalidad latina y mediterránea, es un factor cultural clave para el desarrollo y futura evolución de esta industria. El slogan de la empresa, “Dieta Mediterránea para tu piel”, clarifica en buena medida la idea a desarrollar y los objetivos pretendidos por la estrategia empresarial. Objetivos: El objetivo esencial del TFC es elaborar un estudio detallado para la creación de una empresa de fabricación y comercialización de productos cosméticos de alta gama que abarque el management y la gestión por procesos de la empresa, la función de marketing, el tipo de operaciones y procesos a realizar, la gestión del factor humano y el presupuesto necesario para cubrir este ambicioso proyecto. En detalle, un completo plan de empresa que marque las directrices de la organización industrial que se pretende crear compuesto a su vez por cinco planes: plan de gerencia, plan de marketing, plan de operaciones, plan de recursos humanos y plan económico – financiero. Procedimientos: El proyecto tiene un alto componente de estudio de mercados y de marketing pero pretende también abarcar el management, los procesos de operación, el factor humano y el aspecto económico y financiero de las inversiones y presupuesto necesario. El estudio inicial centrará su esfuerzo en un análisis del mercado de la península ibérica, y, en función del avance y del progreso esperado por la empresa, la compañía podría extender su campo de acción a Europa aunque no antes de un medio plazo. “Vinci Cosmetics” ha adoptado referenciales de sistemas de gestión integrados en toda la organización. Así tenemos principalmente, por un lado, la norma internacional ISO 9001:2008 y, por otro, el Modelo EFQM de Excelencia en la gestión; ambos plasmados a partir de un enfoque basado en procesos que nos garantiza el control continuo y la gestión excelente. Conclusiones: Tras evaluar la situación actual del mercado de la cosmética, las previsiones futuras de éste y las necesidades que una organización industrial necesita, se puede crear - con plenas garantías de éxito como organización empresarial y desde el punto de vista económico - una empresa de cosméticos de alta gama para cubrir las necesidades de una parte de mercado que lo requiere.

Convergence and divergence in global economy and social development : global perspectives on the contents of economic and soical development policy and its effects on rich and poor countries

The study of convergence and divergence in global economy and social development utilises comparative indicators to investigate the contents of economic and social development policy and their effects on the global samples that represent the rich industrial, semi-industrial and the poor developing nations. The study searchesfor answers to questions such as "what are the objectives of economic growth policies in globalisation under the imperatives of convergence and divergence, and how do these affect human well-being in consideration to the objectives of social policy in various nations?" The empirical verification of data utilises the concepts of the `logic of industrialism´ for comparative analysis that focuses mainly on identifying the levels of well-being in world nations after the Second World War. The perspectives of convergence and divergence in global economy and social development critically examine the stages of early development processes in global economy, distinguish the differences between economy and social development, illustrate the contents of economic and social development policies, their effects on rich and poor countries, and the nature of convergence and divergence in propelling economic growth and unequal social development in world nations. The measurement of convergence and divergence in global economy and social development utilised both economic and social data that were combined into an index that measures the precise levels of the effects of economic and social development policies on human well-being in the rich and poor nations. The task of finding policy solutions to resolve the controversies are reviewed through empirical investigations and the analyses of trends indicated within economic and social indicators and data. These revealed how the adoption of social policy measures in translating the gains from economic growth, towards promoting education, public health, and equity, generate social progress and longer life expectancy, higher economic growth, and sustain more stable macro economy for the nations. Social policy is concerned with the translation of benefits from objectives of global economic growth policies, to objectives of social development policy in nation states. Social policy, therefore, represents an open door whereby benefits of economic growth policies are linked with the broader objectives of social development policy, thereby enhancing the possibility of extending benefits from economic growth to all human being in every nation.

Algorithmic Solutions for Combinatorial Problems in Resource Management of Manufacturing Environments

This thesis studies the use of heuristic algorithms in a number of combinatorial problems that occur in various resource constrained environments. Such problems occur, for example, in manufacturing, where a restricted number of resources (tools, machines, feeder slots) are needed to perform some operations. Many of these problems turn out to be computationally intractable, and heuristic algorithms are used to provide efficient, yet sub-optimal solutions. The main goal of the present study is to build upon existing methods to create new heuristics that provide improved solutions for some of these problems. All of these problems occur in practice, and one of the motivations of our study was the request for improvements from industrial sources. We approach three different resource constrained problems. The first is the tool switching and loading problem, and occurs especially in the assembly of printed circuit boards. This problem has to be solved when an efficient, yet small primary storage is used to access resources (tools) from a less efficient (but unlimited) secondary storage area. We study various forms of the problem and provide improved heuristics for its solution. Second, the nozzle assignment problem is concerned with selecting a suitable set of vacuum nozzles for the arms of a robotic assembly machine. It turns out that this is a specialized formulation of the MINMAX resource allocation formulation of the apportionment problem and it can be solved efficiently and optimally. We construct an exact algorithm specialized for the nozzle selection and provide a proof of its optimality. Third, the problem of feeder assignment and component tape construction occurs when electronic components are inserted and certain component types cause tape movement delays that can significantly impact the efficiency of printed circuit board assembly. Here, careful selection of component slots in the feeder improves the tape movement speed. We provide a formal proof that this problem is of the same complexity as the turnpike problem (a well studied geometric optimization problem), and provide a heuristic algorithm for this problem.

Lapsen sosiaalisen kompetenssin tukeminen – vanhempien epäsuorat ja suorat vaikutustavat

Tässä tutkimuksessa tarkastellaan vanhempien havaintoja ja käsityksiä lapsen sosiaalisesta kompetenssista. Lapsen sosiaalisesta kompetenssista tarkastelun kohteena ovat erityisesti vertaissuhteet, sosiaaliset taidot ja sosiaalinen käyttäytyminen. Tarkoituksena on selvittää vanhempien näkemyksiä lapsen sosiaalisesta verkostosta ja lapsesta sosiaalisena toimijana. Kiinnostuksen kohteena on myös, miten vanhemmat vaikuttamaan lapsen sosiaaliseen kompetenssiin. Vanhempien vaikutuksessa voidaan erottaa epäsuora ja suora vaikutus. Vanhempien epäsuoraan vaikutukseen kuuluvat perheen sosioekonomiset tekijät, vanhemmuuteen ja lastenkasvatukseen liittyvät käytännöt sekä lapsen ja vanhemman välinen vuorovaikutus. Suora vaikutus sisältää vanhempien eri roolit ja tehtävät sosiaalisen kompetenssin edistämiseksi. Vanhempien epäsuorilla ja suorilla vaikutustavoilla on havaittu olevan merkittävää vaikutusta lapsen sosiaalisen kompetenssiin muotoutumiseen ja sen laatuun. Tutkimuksessa selvitetään vertaissuhdeongelmaisten ja ei-ongelmaisten lasten vanhempien välisiä eroja näissä vaikutustavoissa. Tutkimuksessa hyödynnetään kyselylomake- ja haastatteluaineistoja. Kyselylomakeaineisto (N=156) kerättiin ”Origins of Exclusion in Early Childhood”-tutkimusprojektissa, jossa tutkittiin lasten vertaissuhteita, sosiaalisia taitoja sekä sosiaalista käyttäytymistä kolmen vuoden seurantatutkimuksena päiväkodista kouluun. Perhekysely toteutettiin lasten ollessa kuusivuotiaita. Vanhempien haastatteluaineisto (N=55) koostuu projektissa mukana olleiden lasten vanhempien teemahaastatteluista. Perhekyselyä analysoidaan tilastollisin analyysimenetelmin. Laadullisen aineiston analyysimenetelmänä käytetään sisällönanalyysia. Vanhempien käsityksissä lasten sosiaalinen verkosto rakentui kotiympäristössä, koulussa, päiväkodissa sekä suvun ja harrastusten parissa muodostuneista suhteista. Tutkimustulosten perusteella on havaittavissa, että vertaissuhdeongelmaisten ja ei-ongelmaisten lasten sosiaaliset verkostot ovat osin erilaiset. Vanhempien arviointien mukaan myös lasten sosiaalisissa taidoissa, käyttäytymisessä, asennoitumisessa sosiaaliseen kanssakäymiseen sekä ryhmään ja leikkeihin liittyvissä strategioissa on eroavaisuuksia. Tutkimuksen pohjalta voidaan todeta, että vanhemmat pystyvät arvioimaan hyvin yksityiskohtaisesti lapsensa sosiaalisia taitoja ja käyttäytymistä. Kaikilla vanhemmilla ei kuitenkaan ollut riittävästi tietoa lasten kaveripiiristä tai sen laadusta eikä lasten sosiaalisesta orientaatiosta. Vanhempien epäsuorissa vaikutustavoissa oli eroja, mutta myös yhtäläisyyksiä. Sosioekonomisia tekijöitä koskevan tarkastelun perusteella vertaissuhdeongelmaisten lasten perheiden taloudelliset ongelmat, isien työttömyys ja lapsen erityisen tuen tarve olivat yhteydessä lapsen sosiaalisten suhteiden ongelmiin. Lähes kaikki tutkimukseen osallistuneet vanhemmat kokivat vanhemmuuden ja kasvatustehtävän kuitenkin hyvin myönteisenä ja tyytyväisyyttä tuottavana asiana elämässä. Valtaosa vanhemmista piti lapsen ja aikuisen välistä vuorovaikutusta positiivisena, vaikka lapsen kanssa ei aina ollutkaan helppoa tulla toimeen. Tyytyväisyydestä huolimatta äidit näkivät itsessään enemmän kehittymisen tarpeita vanhempana kuin isät. Vanhemmuudessa korostuivat ohjaaminen ja kontrolli, mutta myös hoiva, lämpö ja vastavuoroisuus. Hoiva ja lämpö sekä rajojen asettaminen askarruttivat vanhempia suuresti. Vertaissuhdeongelmaisten lasten vanhemmat tarvitsisivat opastusta ohjaavan vanhemmuuden löytämiseksi. Vertaissuhdeongelmaisten lasten vanhemmat kuvasivat kasvatuksen kuormittavuutta, ajan puutetta sekä muuntuvaa isyyttä ja äitiyttä ei-ongelmaisten lasten vanhempia enemmän. Työn ja perheen yhteensovittamisen vaikeus tuli myös esille vanhempien kuvauksissa. Kyvykkään vanhemmuuden kannalta epävirallinen läheisistä muodostunut tukiverkosto on tärkeä vanhemman apu ja kasvatuksen turva. Ensisijaisena tukitahona on epävirallinen verkosto, joka koostuu ystävistä, tuttavista, työtovereista, puolisosta ja omista vanhemmista. Vertaissuhdeongelmaisten lasten vanhempien mukaan arjen tukea ei kuitenkaan ole aina saatavilla, eikä tukiverkosto tyydyttänyt vanhempia. Vanhempien käsityksissä perheen vuorovaikutus sujui hyvin ja vastuu kodista ja kasvatustehtävästä oli molemmilla vanhemmilla tasavertaisesti. Käytännön vastuu kasvatuksesta sekä erilaisten taitojen opettamisesta lapsille kuului äitien tehtäviin. Vanhempien näkemyksissä lapsen sosiaalinen maailma rakentui lähiympäristön tarjoamista mahdollisuuksista. Vanhempien suoriin vaikutustapoihin liittyvien tulosten mukaan vanhemmat pitävät harrastuksia merkittävänä sosiaalista kompetenssia edistävänä tekijänä. Ei-ongelmaisilla lapsilla oli enemmän ja monipuolisempia harrastuksia kuin ongelmaisilla lapsilla. Vaikka vanhemmat eivät mieltäneetkään omaa toimintaansa kaveripiiriin ohjaamiseksi, heillä useinkin oli runsaasti erilaisia rooleja ja tehtäviä sosiaalisten suhteiden ja sosiaalisten taitojen opettamisessa. Lapsen sosiaalisten suhteiden organisoinnissa, ohjaamisessa, valvonnassa ja neuvonnassa oli vanhempiryhmien välillä eroja. Vertaissuhdeongelmaisten lasten vanhemmat eivät olleet riittävän hyvin perillä lapsen taidoista ja kyvykkyydestä tuottaakseen oikea-aikaista ohjausta ja tukeakseen lasta riittävästi sopivilla tavoilla. Vanhempien toimintaa näyttää ohjaavan vakaasti se uskomus, että lapsen kaverisuhteet ovat pelkästään hänen oma asiansa. Vanhemmat arvostivat paljon sosiaalisia taitoja ja pyrkivät opettamaan niitä lapsilleen systemaattisesti. Ohjaamisen tavoissa vanhemmat poikkesivat toisistaan. Tutkimus antaa viitteitä, että eiongelmaisten lasten vanhemmat ovat sensitiivisempiä, vastavuoroisempia ja lapsen näkökulmaa ja tarpeita lähtökohtanaan pitäviä sekä tunnetaitoihin ja tunnetilan käsittelyyn keskittyvämpiä kuin ongelmaisten lasten vanhemmat. Vanhempien ja lasten vuorovaikutuksen vaikeudet, ylimalkainen ja epäjohdonmukainen sosiaalisten taitojen, käyttäytymisen sekä suhteiden ohjaus sekä monet perheen voimavarojen puutteet voivat haitata vakavasti lapsen sosiaalisen kompetenssin kehittymistä. Vanhemmilla on kuitenkin taitoa arvioida lapsensa sosiaalista kyvykkyyttä ja halua toimia hyvin kasvatustehtävässään. Vanhemmuuden tukemisessa olisivatkin tärkeitä epävirallisen tukiverkoston lisäksi lähiympäristön perheille ja lapsille suunnatut palvelut, monitahoinen yhteistyö perheiden, lasten ja heidän kanssaan työskentelevien ammattilaisten kesken sekä yhteiskunnan perheitä koskevat säädökset ja tukitoimet.

Biomass allocation and water use efficiency in fertigated sweet pepper

The use of productivity information and efficiency of water use is important for the economic analysis of production and irrigation management, and also helps the economy of water use, which is essential to plant life. The objective of this study was to evaluate the biomass allocation, the water use efficiency and water content in fruits of sweet pepper cropped under the influence of irrigation blades and potassium doses. The statistic design was a completely randomized factorial scheme (5 x 2) and four replications, with five irrigation blades (80; 90; 100; 110 and 120% of crop evapotranspiration) and two levels of potassium (80 and 120 kg K2O ha-1 ), applied according to phenological phase, through a system of drip irrigation with self-compensated drippers, installed in a battery of 40 drainage lysimeters cultivated with sweet pepper (Maximos F1), at Federal Rural University of Pernambuco (UFRPE), Recife, state of Pernambuco, Brazil. The dry biomass production of sweet pepper was influenced by fertigation regimes; when it was set the lowest dose, estimates of the efficiency of water use and moisture in the fruit occurred with the use of irrigation depth of 97 and 95% of ETc, respectively.

Evaluation of an indicator for water yield in a watershed of Alto Rio Grande Region, State of Minas Gerais , Brazil

The Brazilian Law stipulates that water is a limited natural resource doted of economic value, thus it is necessary to develop mechanisms for its adequate management. Actions that encourage the farmers to apply soil conservation practices with the purpose of increase water yield from springs and to promote improvement of its quality, reducing production of sediment transportation, is being encouraged by governments, even with financial compensation for owners. From these assertions, this study aims to quantify the benefits of the conservation actions of the management units and to characterize a Water Yield Indicator (WYI) to support sustainable actions in the watershed of Alto Rio Grande region, in the state of Minas Gerais (MG). To assess the impact of actions it were identified four scenarios of land use and occupation of the watershed from Marcela stream which is located in Alto Rio Grande Region. After analyzing the results, it can be stated that the scenarios simulation has demonstrated important changes in water yield and that the definition of the Water Yield Index from the junction of the erosion potential with the water storage potential, has proved effective, as it integrate quantity and quality of water.

Rational use of water in a poultry slaughterhouse in the state of Paraná, Brazil: a case study

Agroindustries are major consumers of water. However, to adapt to environmental trends and be competitive in the market, they have sought rational use of water through water management in their activities. Cleaner Production can result in economic, environmental and social benefits, and in actions that promote reduction in water consumption. This case study was conducted in a slaughterhouse and poultry cold storage processing plant and aimed to identify points of excessive water consumption, and to propose alternatives for managing water resources by reducing consumption. Consumption data are presented in relation to the processing stages with alternatives proposed for the rational use of water, such as closure of mains water during shift changes. Following the implementation of recommendations, a reduction in water consumption of approximately 11,137 m³ per month was obtained, which equates to a savings of US$ 99,672 per year. From this study, it was concluded that the company under review could develop various improvement actions and make an important contribution to the preservation of water resources in the region where it operates.

Technical-economic analysis of different lighting systems for broiler poultry

ABSTRACT Broiler poultry is highly dependent on artificial lightening. Power consumption costs of artificial lighting systems is the second largest expense related to broiler industry, second only to feed expenses. Therefore, the current study focused to analyze technical and economic feasibility of replacing incandescent lamps already used in aviaries with other lamp types. Costs related to power consumption, implementation and maintenance of the lighting systems were evaluated with the aid of financial mathematics using net present value, return over investment and payback. Systems composed of six lamp types were analyzed in two different configurations to meet the minimum illuminance of 5 and 20 lux and for use in conventional sheds and dark house. The lamps tested were incandescent (LI) of 100 W, compact fluorescent (CFL) of 34 W, mixed (ML) 160 W sodium vapor (SVL) of 70 W, tubular fluorescent T8 (TFL T8) of 40 W and tubular fluorescent T5 (TFL T5) of 28 W. For the systems tested, it was found that the tubular fluorescent lamps T8 and T5 showed the best results of technical and economic feasibility.

An Infant with Food Allergy and Eczema in the Family – The Mental and Economic Burden of Caring

Allergic diseases including food allergy and eczema in an infant in combination with the everyday activities of caring for a family will pose challenges to parents. Only fragments of these challenges are revealed to health care professionals. Families have varying mental, social and economic resources to help them care for an allergic infant, and all such resources are important in determining how families succeed in meeting these challenges and the quality of the infant’s care. This study evaluated the whole burden to the family caused by an infant's allergic disease during the first 24 months of life. As the primary caregiver during this period is usually the mother, her perspective was considered important. Ecocultural theory, which considers families as capable of modifying the positive and negative forces facing them, was taken as the frame of reference. Data were collected as part of an ongoing prospective mother-infant study, and the methods included severity scoring of atopic dermatitis, dietary records, health-related quality of life measurements and assessments of the use of health care services and medications for treating the infant’s eczema, food allergy and asthma. Interviews with mothers were analysed by deductive content analysis on the basis of ecocultural theory and the family empowerment model. The theme “Living an ordinary family life” guided the organization of family activities essential for treating the infant's food allergy and eczema. These activities were sources of both strain and support for the mothers, the allergy-related supporting factors being the mother’s own knowledge of the allergy, hopes for an improvement in the infant’s condition, social support and work. An infant’s food allergy at the age of one year caused considerable strain for the mother in cases where the introduction of new foods into the child’s diet was delayed. This delay was still causing the mother additional strain when the child was 24 months of age. The infants waking at night at the ages of 12 and 24 months because of itching related to eczema caused strain for the mothers. The infants’ health-related quality of life was impaired at ages of 6 and 12 months compared with healthy infants. The principal reasons for impairments were itching, scratching and sleep disturbances at 6 and 12 months and treatment difficulties at 6 months. Problems with getting to sleep were reported at all stages irrespective of eczema and were also present in healthy infants. The economic impact of the treatment of allergic diseases on families during the first 24 months was 131 EUR (2006 value) in cases of eczema and 525 EUR in cases of food allergy. From the societal perspective, the costs of food allergy were a median of 3183 EUR (range 628–11 560 EUR) and of eczema a median of 275 EUR (range 94–1306 EUR). These large variations in costs in food allergy and eczema indicate that disease varies greatly . In conclusion, food allergy and eczema cause extra activities and costs to families which arrange these disease-related activities in such a way that they support the leading family theme “Living an ordinary family life”. Health care professionals should consider this thematic character of family life and disease-related activities in order to ensure that new treatments are sustainable, meaningful and tailored to daily activities. In addition, those mothers who are experiencing difficulties with food allergic infants or infants with eczema should be recognized early and provided with individual encouragement and support from health clinics. In the light of the present results, early detection of symptoms and effective parental guidance can contribute to the well-being and health-related quality of life of the child and family.

The cost of excessive postoperative use of antimicrobials: the context of a public hospital

OBJECTIVE: To evaluate the improper use of antimicrobials during the postoperative period and its economic impact.METHODS: We conducted a prospective cohort study by collecting data from medical records of 237 patients operated on between 01/11/08 and 31/12/08.RESULTS: from the 237 patients with the information collected, 217 (91.56%) received antimicrobials. During the postoperative period, 125 (57.7%) patients received more than two antimicrobials. On average, 1.7 ± 0.6 antimicrobials were prescribed to patients, the most commonly prescribed antibiotic being cephalothin, in 41.5% (154) of cases. The direct cost of antimicrobial therapy accounted for 63.78% of all drug therapy, this large percentage being attributed in part to the extended antimicrobial prophylaxis. In the case of clean operations, where there was a mean duration of 5.2 days of antibiotics, antimicrobials represented 44.3% of the total therapy cost.CONCLUSION: The data illustrate the impact of overuse of antimicrobials, with questionable indications, creating situations that compromise patient safety and increasing costs in the assessed hospital.

Social ventures : the development of the theory of sustainable contributive advantage and initial empirical tests

This thesis attempts to fill gaps in both a theoretical basis and an operational and strategic understanding in the areas of social ventures, social entrepreneurship and nonprofit business models. This study also attempts to bridge the gap in strategic and economic theory between social and commercial ventures. More specifically, this thesis explores sustainable competitive advantage from a resource-based theory perspective and explores how it may be applied to the nonmarket situation of nonprofit organizations and social ventures. It is proposed that a social value-orientation of sustainable competitive advantage, called sustainable contributive advantage, provides a more realistic depiction of what is necessary in order for a social venture to perform better than its competitors over time. In addition to providing this realistic depiction, this research provides a substantial theoretical contribution in the area of economics, social ventures, and strategy research, specifically in regards to resource-based theory. The proposed model for sustainable contributive advantage uses resource-based theory and competitive advantage in order to be applicable to social ventures. This model proposes an explanation of a social venture’s ability to demonstrate consistently superior performance. In order to determine whether sustainable competitive advantage is in fact, appropriate to apply to both social and economic environments, quantitative analyses are conducted on a large sample of nonprofit organizations in a single industry and then compared to similar quantitative analyses conducted on commercial ventures. In comparing the trends and strategies between the two types of entities from a quantitative perspective, propositions are developed regarding a social venture’s resource utilization strategies and their possible impact on performance. Evidence is found to support the necessity of adjusting existing models in resource-based theory in order to apply them to social ventures. Additionally supported is the proposed theory of sustainable contributive advantage. The thesis concludes with recommendations for practitioners, researchers and policy makers as well as suggestions for future research paths.

Uutta tietoa Kainuun soista : Kainuun suoselvitys -projektin tulosraportti

Raportissa esitellään Kainuun suoselvitys -projektin keskeisimpiä tuloksia ja niistä vedettyjä johtopäätöksiä. Vuosina 2010–2012 toteutetun projektin tarkoituksena on ollut parantaa tietopohjaa Kainuun soista, ja sitä kautta luoda edellytyksiä soiden eri käyttömuotojen yhteensovittamiselle ja samalla nostaa esille Kainuun soihin liittyviä mahdollisuuksia. Soiden käyttö nähtiin projektissa laajasti, sisältäen paitsi erilaiset taloudellisen hyödyntämisen muodot myös soiden merkityksen ihmisten virkistykselle ja hyvinvoinnille sekä luonnon monimuotoisuudelle ja monille sääteleville toiminnoille. Taustana projektille on samaan aikaan laadittu kansallinen suostrategia. Sen mukaan soiden luonnontilaa muuttavien toimintojen, maa-, metsä- ja turvetalouden, tulisi jatkossa toimia jo ojitetuilla tai muuten merkittävästi muuttuneilla soilla. Näin soiden luonnontilaisuudesta hyötyville soiden käytön muodoille ja ekosysteemipalveluille jää paremmin tilaa toimia. Kainuu on Suomen kolmanneksi soisin maakunta. Suot ovat keskeinen osa sen luontoa ja maisemaa ja myös monipuolinen luonnonvara. Valtaosa Kainuun suopinta-alasta on ojitettu. Uutta tietoa on projektissa tuotettu paikkatietomenetelmin ja kohdennetuin maastoselvityksin. Raportin aihepiirejä ovat Kainuun soiden käyttö, jäljellä olevat ojittamattomat suot, suojeltujen soiden vesitaloudellinen eheys, metsätalouden käytöstä poistuvat ojitetut suot, soiden merkitys virkistyksen ja matkailun kannalta sekä maastossa tutkittujen 143 suon arviointi turpeennoston ja luonnon monimuotoisuuden kannalta. Raportissa esitetään, että kansallisen suostrategian tavoite soiden kestävästä ja vastuullisesta käytöstä ja suojelusta on mahdollista saavuttaa eri toimijoiden yhteistyön ja maankäytön ohjauksen avulla. Se edellyttää sitoutumista suostrategian linjauksiin sekä tietopohjan parantamista soista ja eri toimintojen vaikutuksista. Kainuun suoselvitys -projektissa on osaltaan tuotettu tätä tietoa ja myös kehitelty menetelmiä sen hankkimiseksi.

Tertiary Treatment and Re-use of Kraft Pulp Mill Effluent

The efficient use of materials and natural recourses, for ecological and economic reasons, has become more and more important in all industries. In the forest industries this means higher levels of closure in the material circulations of the mills. One possibility to reduce wastewater discharge is to re-use part of the 2nd clarifier effluent as process water. The main target of this thesis was to evaluate the technical suitability of several mechanical and chemical tertiary treatment methods for water re-use. Some of the tested methods seemed to have high potential for the removal of some specific constituents from the wastewater. Tertiary treatment is needed because higher levels of closure may cause problems with increasing amounts of non-process elements in different points of kraft pulp process. The aspect of sustainable development was taken into account by evaluating positive and negative environmental effects of the treatment processes. Environmental benefits can be gained by using some of the tertiary treatment methods tested. These methods should still be researched more for system optimization.
