According to U.S. Small Business Association, the failure rates for small businesses in 2014 were as high as 50% to 80% within the first 5 years of establishment. Failure rates were especially high among restaurant businesses. The purpose of this study was to explore the strategies that small business owners needed to sustain their businesses beyond the first 5 years. Guided by entrepreneurship theory as the conceptual framework, a case study was conducted with semistructured interviews of 3 successful Thai restaurant owners in Salt Lake City, Utah. Member checking and methodological triangulation with field notes, interview data, company websites, customer comments, and government documents help ensure theoretical saturation and trustworthiness of interpretations. Using precoded themes for the data analysis, the 7 themes from this study were entrepreneur characteristics, education and management skills, marketing strategies and competitive advantages, social networks and human relationships, technology and innovation, government supports and social responsibility, and financial planning. Two key results indicated the strategies that were needed for small business owners were entrepreneur management skills and government support for small businesses. These findings may influence positive social change by improving small business owner efficiency and sustainability, increasing higher business income, providing a better quality of living for employees and the well-being of the community, and benefiting the U.S. economy.

Daten werden noch immer groesstenteils in Dateien und nicht in Datenbanken gespeichert. Dieser Trend wird durch den Internetboom der 90er Jahre nur noch verstaerkt. Daraus ist das Forschungsgebiet der semistrukturierten Daten entstanden. Semistrukturierte Daten sind Daten, die meist in Dokumenten gespeichert sind und eine implizite und irregulaere Struktur aufweisen. HTML- oder BibTeX-Dateien oder in ASCII-Dateien gespeicherte Genomdaten sind Beispiele. Traditionelles Datenbankmanagement erfordert Design und sichert Deklarativitaet zu. Dies ist im Umfeld der semistrukturierten Daten nicht gegeben, ein flexiblerer Ansatz wird gebraucht. In dieser Arbeit wird ein neuer Ansatz des Abfragens semistrukturierter Daten praesentiert. Wir schlagen vor, semistrukturierte Daten durch eine Menge von partiellen Schemata zu beschreiben, anstatt zu versuchen, ein globales Schema zu definieren. Letzteres ist zwar geeignet, einen effizienten Zugriff auf Daten zu ermoeglichen; ein globales Schema fuer semistrukturierte Daten leidet aber zwangslaeufig an der Irregularitaet der Struktur der Daten. Wegen der vielen Ausnahmen vom intendierten Schema wird ein globales Schema schnell sehr gross und wenig repraesentativ. Damit wird dem Nutzer ein verzerrtes Bild ueber die Daten gegeben. Hingegen koennen partielle Schemata eher ein repraesentatives Bild eines Teils der Daten darstellen. Mit Hilfe statistischer Methoden kann die Guete eines partiellen Schemas bewertet werden, ebenso koennen irrelevante Teile der Datenbank identifiziert werden. Ein Datenbanksystem, das auf partiellen Schemata basiert, ist flexibler und reflektiert den Grad der Strukturierung auf vielen Ebenen. Seine Benutzbarkeit und seine Performanz steigen mit einem hoeheren Grad an Struktur und mit seiner Nutzungsdauer. Partielle Schemata koennen auf zwei Arten gewonnen werden. Erstens koennen sie durch einen Datenbankdesigner bereitgestellt werden. Es ist so gut wie unmoeglich, eine semistrukturierte Datenbank komplett zu modellieren, das Modellieren gewisser Teile ist jedoch denkbar. Zweitens koennen partielle Schemata aus Benutzeranfragen gewonnen werden, wenn nur die Anfragesprache entsprechend entworfen und definiert wird. Wir schlagen vor, eine Anfrage in einen ``Was''- und einen ``Wie''-Teil aufzuspalten. Der ``Was''-Teil wird durch partielle Schemata repraesentiert. Partielle Schemata beinhalten reiche semantische Konzepte, wie Variablendefinitionen und Pfadbeschreibungen, die an Konzepte aus Anfragesprachen angelehnt sind. Mit Variablendefinitionen koennen verschiedene Teile der Datenbank miteinander verbunden werden. Pfadbeschreibungen helfen, durch das Zulassen einer gewissen Unschaerfe, die Irregularitaet der Struktur der Daten zu verdecken. Das Finden von Stellen der Datenbank, die zu einem partiellen Schema passen, bildet die Grundlage fuer alle Arten von Anfragen. Im ``Wie''-Teil der Anfrage werden die gefundenen Stellen der Datenbank fuer die Antwort modifiziert. Dabei koennen Teile der gefundenen Entsprechungen des partiellen Schemas ausgeblendet werden oder auch die Struktur der Antwort voellig veraendert werden. Wir untersuchen die Ausdrucksstaerke unserer Anfragesprache, in dem wir einerseits die Operatoren der relationalen Algebra abbilden und andererseits das Abfragen von XML-Dokumenten demonstrieren. Wir stellen fest, dass das Finden der Entsprechungen eines Schemas (wir nennen ein partielles Schema in der Arbeit nur Schema) den aufwendigsten Teil der Anfragebearbeitung ausmacht. Wir verwenden eine weitere Abstraktionsebene, die der Constraint Satisfaction Probleme, um die Entsprechungen eines Schemas in einer Datenbank zu finden. Constraint Satisfaction Probleme bilden eine allgemeine Klasse von Suchproblemen. Fuer sie existieren bereits zahlreiche Optimierungsalgorithmen und -heuristiken. Die Grundidee besteht darin, Variablen mit zugehoerigen Domaenen einzufuehren und dann die Werte, die verschiedene Variablen gleichzeitig annehmen koennen, ueber Nebenbedingungen zu steuern. In unserem Ansatz wird das Schema in Variablen ueberfuehrt, die Domaenen werden aus der Datenbank gebildet. Nebenbedingungen ergeben sich aus den im Schema vorhandenen Praedikaten, Variablendefinitionen und Pfadbeschreibungen sowie aus der Graphstruktur des Schemas. Es werden zahlreiche Optimierungstechniken fuer Constraint Satisfaction Probleme in der Arbeit vorgestellt. Wir beweisen, dass die Entsprechungen eines Schemas in einer Datenbank ohne Suche und in polynomialer Zeit gefunden werden koennen, wenn das Schema ein Baum ist, keine Variablendefinitionen enthaelt und von der Anforderung der Injektivitaet einer Einbettung abgesehen wird. Zur Optimierung wird das Enthaltensein von Schemata herangezogen. Das Enthaltensein von Schemata kann auf zwei Weisen, je nach Richtung der Enthaltenseinsbeziehung, genutzt werden: Entweder kann der Suchraum fuer ein neues Schema reduziert werden oder es koennen die ersten passenden Stellen zu einem neuen Schema sofort praesentiert werden. Der gesamte Anfrageansatz wurde prototypisch zunaechst in einem Public-Domain Prolog System, spaeter im Constraintsystem ECLiPSe implementiert und mit Anfragen an XML-Dokumente getestet. Dabei wurden die Auswirkungen verschiedener Optimierungen getestet. Ausserdem wird eine grafische Benutzerschnittstelle zur Verfuegung gestellt. / Most of today's data is still stored in files rather than in databases. This fact has become even more evident with the growth of the World Wide Web in the 1990s. Because of that observation, the research area of semistructured data has evolved. Semistructured data is typically stored in documents and has an irregular, partial, and implicit structure. The thesis presents a new framework for querying semistructured data. Traditional database management requires design and ensures declarativity. The possibilities to design are limited in the field of semistructured data, thus, a more flexible approach is needed. We argue that semistructured data should be represented by a set of partial schemata rather than by one complete schema. Because of irregularities of the data, a complete schema would be very large and not representative. Instead, partial schemata can serve as good representations of parts of the data. While finding a complete schema turns out to be difficult, a database designer may be able to provide partial schemata for the database. Also, partial schemata can be extracted from user queries if the query language is designed appropriately. We suggest to split the notion of query into a ``What''- and a ``How''-part. Partial schemata represent the ``What''-part. They cover semantically richer concepts than database schemata traditionally do. Among these concepts are predicates, variable definitions, and path descriptions. Schemata can be used for query optimization, but they also give users hints on the content of the database. Finding the occurrences (matches) of such a schema forms the most important part of query execution. All queries of our approach, such as the focus query or the transformation query, are based on this matching. Query execution can be optimized using knowledge about containment relationships between different schemata. Our approach and the optimization techniques are conceptually modeled and implemented as a prototype on the basis of Constraint Satisfaction Problems (CSPs). CSPs form a general class of search problems for which many techniques and heuristics exist. A CSP consists of variables that have a domain associated to them. Constraints restrict the values that variables can simultaneously take. We transform the problem of finding the matches of a schema in a database to a CSP. We prove that under certain conditions the matches of a schema can be found without any search and in polynomial time. For optimization purposes the containment relationship between schemata is explored. We formulate a sufficient condition for schema containment and test it again using CSP techniques. The containment relationship can be used in two ways depending on the direction of the containment: It is either possible to reduce the search space when looking for matches of a schema, or it is possible to present the first few matches immediately without any search. Our approach has been implemented into the constraint system ECLiPSe and tested using XML documents.

While unstructured merge tools try to automatically resolve part of the conflicts via textual similarity, semistructured tools try to go further by exploiting the syntactic structure of part of the artefacts involved. To understand the impact of the unstructured and semistructured merge approaches on integration effort (Productivity) and correctness of the merging process (Quality), we conduct two empirical studies. In the first one, aiming at increasing the existing body of evidence and assessing results for systems developed under an alternative version control paradigm, we replicate an experiment to compare the unstructured and semistructured approaches with respect to the number of conflicts reported by both merge approaches. We used both semistructured and unstructured merge in a sample 2.5 times bigger than the original study regarding the number of projects and 18 times bigger regarding the number of performed merges, and we compared the occurrence of conflicts. Similar to the original study, we observed that semistructured merge reduces the number of conflicts in 55% of the performed merges of the new sample. Besides that, the observed average conflict reduction of 62% in these merges is far superior than what has been observed before. We also bring new evidence that the use of semistructured merge can reduce the occurrence of conflicting merges by half. In order to verify the frequency of false positives and false negatives arising from the use of these merge approaches, we move forward and we conduct a second empirical study. We compare the unstructured and semistructured merge approaches by reproducing more than 30,000 merges from 50 projects, and collecting evidence about reported conflicts that do not represent interferences between development tasks (false positives), and interferences not reported as conflicts (false negatives). In particular, our assumption is that false positives amount to unnecessary integration effort because developers have to resolve conflicts that actually do not represent interferences. Besides that, false negatives amount to build issues or bugs, negatively impacting software quality and correctness of the merging process. By analyzing such critical factors we hope to guide developers on deciding which approach should be used in practice. Finally, our results show that semistructured merge eliminates a significant part of the false positives reported by unstructured merge, but brings false positives of its own. The overall number of false positives is reduced with semistructured merge, and we argue that the conflicts associated to its false positives are easier to resolve when comparing to the false positives reported by unstructured merge. We also observe that more interferences were missed by unstructured merge and reported by semistructured merge, but we argue that the semistructured merge ones are harder to detect and resolve than the other way around. Finally, our study suggests how a semistructured merge tool could be improved to eliminate the extra false positives and negatives it has in relation to unstructured merge. / Durante a integração de contribuições de código resultantes das tarefas de desenvolvimento, frequentemente desenvolvedores têm que lidar com alterações conflitantes e dedicar considerável esforço para resolver conflitos. Enquanto as ferramentas de integração não-estruturadas tentam resolver automaticamente parte dos conflitos através de similaridade textual, ferramentas semiestruturadas tentam ir mais longe, explorando a estrutura sintática de parte dos artefatos envolvidos. Para entender o impacto das abordagens de integração não-estruturada e semiestruturada sobre esforço de integração (Produtividade) e corretude do processo de integração (Qualidade), nós realizamos dois estudos empíricos. No primeiro, com o objetivo de aumentar o atual corpo de evidência e avaliar resultados para sistemas desenvolvidos usando um paradigma de controle de versão alternativo, nós replicamos um experimento para comparar a abordagem não-estruturada e semiestruturada de acordo com o número de conflitos reportados por ambas as abordagens. Nós usamos tanto a integração semiestruturada quanto a não-estruturada em uma amostra 2,5 vezes maior do que a do estudo original em relação ao número de projetos e 18 vezes maior em relação ao número de integrações realizadas, e comparamos a ocorrência de conflitos. Semelhante ao estudo original, observamos que a integração semiestruturada reduz o número de conflitos em 55% das integrações da nova amostra. Além disso, a redução de conflitos média observada de 62% nestas integrações é muito superior à observada anteriormente. Nós também trazemos nova evidência de que o uso da abordagem semiestruturada pode reduzir a ocorrência de integrações com conflitos pela metade. Com o intuito de verificar a frequência de falsos positivos e falsos negativos originados do uso dessas abordagens, nós seguimos adiante e conduzimos um segundo estudo empírico. Nós comparamos as abordagens reproduzindo mais de 30.000 integrações de 50 projetos, coletando evidência sobre os conflitos reportados que não representam interferências entre as tarefas de desenvolvimento (falsos positivos), e interferências não reportadas como conflitos (falsos negativos). Em particular, a nossa suposição é de que falsos positivos denotam esforço desnecessário de integração porque os desenvolvedores têm que resolver conflitos que, na realidade, não representam interferências. Além disso, falsos negativos denotam problemas de build ou bugs, impactando negativamente a qualidade do software e corretude do processo de integração. Ao analisar esses fatores críticos, esperamos orientar os desenvolvedores em decidir qual abordagem deve ser usada na prática. Finalmente, nossos resultados mostram que a abordagem semiestruturada elimina uma parte significativa dos falsos positivos reportados pela abordagem não-estruturada, mas traz falsos positivos próprios. O número global de falsos positivos é reduzido com a integração semiestruturada, e nós argumentamos que os conflitos associados aos seus falsos positivos são mais fáceis de resolver quando comparados aos falsos positivos reportados pela abordagem não-estruturada. Observamos, também, que mais interferências deixaram de ser detectadas pela abordagem não-estruturada, mas foram detectadas pela semiestruturada. No entanto, nós acreditamos que as interferências não detectadas pela abordagem semiestruturada são mais difíceis de detectar e resolver. Por fim, nosso estudo sugere como uma ferramenta de integração semiestruturada poderia ser melhorada para eliminar os falsos positivos e falsos negativos adicionados que possui em relação à não-estruturada.

This is a qualitative actions research study of pre school teachers’ reflections about their choices and actions. The qualitative actions research study is combined with semistructured interviews, mind map-conversations and a videocamera in order to bring awareness about the pedagogs actions. The theory i use to analys the results is poststructural discourse. The aim is to understand and investigate how and if teachers in preschool change their analyses and reflections practice, during their action research process. Another purpose, during this process, is to understand how the pre school teachers reflect and value their knowledge in the context of their profession and practice. The questions i aim to answer are:1. In which ways does the action research process change the pre school teachers reflectionspractice?2. How do the pre school teachers reflect upon and value their knowledge about their profession within their practice?The conclusion is that action research, semistructured interviews, mind map- conversations and the observered material from the videocamera led the preschool teachers to develop at their own pace, and from their own problemed based questions and thoughts. They go from a structure view on the pedagogical practice to a subjective self evaluation view, where change is possible and their own knowledge about their profession becomes visible.

Introduktion: Covid-19 pandemin har i Sverige inneburit förändringar på samhällelig nivå såsom restriktioner och allmänna råd i syfte att minska smittspridningen. Omställningar inom den svenska hälso- och sjukvården innebar att operationssjukvården påverkades i form av att antalet elektiva operationer minskade. Studier angående operationssjuksköterskors erfarenheter av kliniskt arbete under covid-19 pandemin saknas. Syfte: Syftet var att beskriva operationssjuksköterskors erfarenheter av kliniskt arbete under covid-19 pandemin. Metod: En kvalitativ intervjustudie utfördes och data samlades in genom nio semistrukturerade intervjuer med operationssjuksköterskor på ett sjukhus i de norra delarna av Sverige. Transkriberade intervjuer analyserades med stöd av kvalitativ innehållsanalys. Resultat: Analys av insamlade data resulterade i tre kategorier, -Samma arbete, nya förutsättningar, -Att ställa om till en ny arbetsplats, och -Tankar om framtiden. Slutsats: Operationsarbetet har inte påverkats i den uträckning som operationssjuksköterskorna först befarat. Tydliga rutiner vid operationer av covid-19 patienter underlättar för operationssjuksköterskorna. Bristande förberedelse och inskolning vid förflyttning till IVA medförde osäkerhet kring arbetsuppgifter.

Bakgrund: På en operation finns det en risk för att exponeras för blodsmittor när operationssjuksköterskor handhar vassa föremål samt kan utsättas för blodstänk. Blodburna sjukdomar som hiv, hepatit B och C sprids via smittat blod som kommer i kontakt med skadad hud eller slemhinnor. Stick- eller skärskador samt blodstänk är vanligast. Patienter med en blodsmitta kan uppleva ett stigma på grund av sin sjukdom. Vårdpersonal ska behandla alla lika och får inte diskriminera patienter.  Motiv: Operationssjuksköterskor arbetar i en miljö där det finns en risk för exponering av blodsmittor, det är därför av värde att undersöka operationssjuksköterskors erfarenheterrelaterade till blodsmitta. Syfte: Att belysa operationssjuksköterskors erfarenheter relaterade till blodsmitta.  Metod: Individuella semistrukturerade intervjuer genomfördes med operationssjuksköterskor (n=8). Insamlade data analyserades enligt kvalitativ innehållsanalys Resultat:  Analysen resulterade i tre olika kategorier: “Att uppleva risk”, “Att känna sig trygg” samt “Att ständigt utvecklas”.   Konklusion: Med erfarenhet blir specialistsjuksköterskan inom operation mer trygg i arbetet med en patient med känd blodsmitta. Tillgänglighet till information och bra rutiner är en central del då det annars kan skapa osäkerhet då operationssjuksköterskans arbete är i ständig utveckling och nya rutiner tillkommer. Det finns en risk att patienter inte vågar berätta för risk av stigmatisering och diskriminering och det är inte säkert att alla bärare av blodsmitta har testats. Alla patienter ska därför ses som potentiella smittbärare. / Background: During surgery there is a risk of exposure to blood-borne pathogens due to the handlings of sharp objects and exposure from blood splash. Blood-borne pathogens like HIV, hepatitis B and hepatitis C spread when contaminated blood comes in contact with damaged skin, mucous membranes or by an injury with a contaminated instrument. Sharps-injuries and blood-splash are the most common forms of exposure in the operating theatre. Patients with a blood-borne infection can feel stigmatized due to their illness. Health care personnel must provide equal care, and not discriminate against patients Motive: Theatre nurses work in an environment where there is risk of exposure of blood-borne pathogens, it is therefore of value to examine theatre nurses' experiences related to blood-borne pathogensAim: To shed light on operating theatre nurses' experiences related to blood-borne pathogens. Methods: Individual semi-structured interviews were conducted with operating theatre nurses (n=8). Collected data were analyzed according to qualitative content analysis. Result: The analysis resulted in three different categories: "Experiencing risk", "Feeling safe" and "Constantly developing". Conclusion: The theatre nurse gains confidence in working with patients with known blood-borne pathogens with experience. Availability of information and good routines are important factors as it can otherwise create uncertainty due to the constantly developing nature of the operating theatre nurse's work, and the adding of new routines. There is a risk that patients avoid disclosure of infection in fear of stigmatization and discrimination, and not all carriers of blood-borne pathogens have been tested and diagnosed.  Therefore, all patients should be seen as potential carriers.

The industry that shows the strongest growth and development online is the foodindusty. The prognosis shows that this development will only continue to increase. One problem with the online grocery shopping lies in the fact that consumers find it difficult to differentiate the product packaging. Consumers also find it more difficult to evaluate the product traits online versus in physical stores. Companies must therefore start thinking about designing packaging that should also fit digitally. Companies who do not adapt to the new digital landscape run the risk of losing customers, see the margins fall and being out- competed by other companies who have come further in this work. This study therefore aims to analyze which communicative elements on the digital packaging that consumers consider ease their purchasing decisions when shopping for groceries online. This is to be able to create direct communication on the digital packaging which in turn can lead to purchases. In order to examine this, theories in visual communication and consumer purchasing behavior have been analyzed as secondary data together with primary data in the form of three focus groups and fifteen semi-structured interviews. The interview answers have then been analyzed and set against previous theories. This led to the following conclusions: The communicative elements on the digital packaging that consumers consider eases their purchasing decisions when shopping for groceries online are: Consumers want to be able to easily see the brand's logotype and quantity/volume must be clearly stated. It is also important to have an image presenting the packaging's content, clearly state what the product is and labels, especially in the form of eco-labels and origin. / Den bransch som visar på den starkaste tillväxten och utvecklingen online är livsmedelshandeln. Prognosen visar att denna utveckling bara kommer fortsätta öka. En problematik med handeln av livsmedel online ligger i att konsumenter nästan inte ser någon skillnad på förpackningarna. Konsumenter har även svårare att utvärdera produktegenskaper online kontra fysisk butik. Företag måste därmed börja tänka på att designa förpackningar som även ska passa digitalt. Företag som inte anpassar sig till det nya digitala landskapet riskerar förlora kunder, se marginalerna falla och bli utkonkurrerade av andra aktörer som kommit längre i detta arbete. Denna studie syftar därmed till att undersöka vilka kommunikativa element på digitala förpackningar som konsumenter anser underlättar deras köpbeslut när de handlar livsmedel online. Detta för att kunna skapa en tydlig kommunikation på digitala förpackningar som i sin tur ska kunna leda till köp. För att undersöka detta har författarna analyserat teorier inom visuell kommunikation och konsumentköpbeteende som sekundärdata tillsammans med primärdata i form av tre fokusgrupper samt femton semistrukturerade intervjuer. Intervjusvaren har sedan analyserats och ställts mot tidigare teorier. Våra slutsatser är följande: De kommunikativa element på digitala förpackningar som konsumenter anser underlättar deras köpbeslut när de handlar livsmedel online är: Att lätt kunna se varumärkets logotyp och att mängd/volym tydligt framgår. Det är också viktigt med en bild som förmedlar förpackningens innehåll, vad det är för produkt och märkningar, framförallt i form av miljömärkningar och ursprung.

Em todo o mundo, existe uma crescente competição pelo uso de água entre os diversos setores da sociedade. A agricultura é uma grande consumidora do total de água doce disponível. Neste contexto, é desejável uma realocação dos recursos hídricos usados na agricultura para outros setores, tais como o abastecimento público. Desde que realizada de forma controlada, a irrigação com efluentes de estação de tratamento de esgoto (EETE) é altamente atrativa, pois além de possibilitar a liberação de recursos hídricos de melhor qualidade para outras atividades humanas, serve como uma forma de tratamento complementar do efluente, fornecendo ainda água e nutrientes essenciais aos cultivos agrícolas. No entanto, o uso sustentável dos EETEs na agricultura depende não apenas dos aspectos químicos, físicos e biológicos do sistema soloplanta- água, como também de aspectos sócio-econômicos. Assim, o presente trabalho teve por objetivo estudar os efeitos da irrigação com EETE no agrossistema, avaliando a aceitação da prática pelo proprietário rural e mapeando as áreas potencialmente irrigáveis com efluente no município de Lins. Dos 15 proprietários entrevistados, todos se mostraram favoráveis à prática e destinariam, ao menos uma parte da propriedade, para irrigação com o EETE. O fato do resíduo (efluente) originar-se do tratamento de esgoto urbano não influenciou a percepção dos agricultores quanto ao potencial de aproveitamento agrícola do efluente. O principal fator determinante da maior ou menor aceitação da prática diz respeito aos possíveis ganhos econômicos envolvidos (maior produtividade e menor despesa com fertilizantes minerais). Para os proprietários, o maior empecilho à adoção generalizada da prática corresponde aos custos envolvidos no transporte do efluente até as propriedades. Da área total do município de Lins, 73,42% estão cultivados com pastagens e cana-de-açúcar. Considerando-se as instruções técnicas utilizadas para a definição das áreas apropriadas para irrigação com efluente, existe no município um potencial de 112,9 km2 de áreas aptas, ou seja, 19,82% da área total do município passível de receber EETE via irrigação por aspersão. A inexistência de bases legais que regulamentem o uso deste subproduto, se apresenta como o principal fator limitante para a irrigação de culturas no município de Lins. / Worldwide, there is an increasing competition for the use of water between different sectors of society. The agriculture is a major consumer of the total fresh water available. In this context, it is desirable a reallocation of water resources used in agriculture to other sectors, such as public supply. Since done in a controlled way, irrigation with effluent from sewage treatment plants (TSE) is highly attractive, enabling the release of better water quality sources for other human activities, serving as a complementary treatment of the effluent, also providing water and essential nutrients to agricultural crops. However, the sustainable agricultural use of TSE depends not only of chemical, physical and biological aspects of the soil-plant-water system, but also of socioeconomic aspects. Thus, this study aimed to investigate the effects of TSE irrigation in the agrosystem, evaluating the acceptance of the practice by the rural owners and mapping the potentially effluent irrigable areas in the city of Lins. Of the 15 rural owners interviewed, all were in favor of the practice and could reserve, at least a part of the property, for the irrigation with TSE. The fact that the waste (effluent) originates from the treatment of urban sewage has not influenced the perception of farmers about the potential agricultural use of the effluent. The main determining factor of greater or lesser acceptance of the practice relates to the possible economic gains involved (greater productivity and lower expenses with mineral fertilizers). For the rural owners, the biggest drawback to a widespread adoption of the practice corresponds to the costs involved in transporting the sewage to the properties. Of the total area of the municipal district of Lins, 73.42% are cultivated with grassland grass and sugarcane. Considering the technical instructions employed to define the suitable areas for effluent irrigation, there is a local potential of 112.9 km2 of suitable areas, or 19.82% of the total area of the municipality may receive STE via sprinkler irrigation. The lack of legal basis regulating the use of this byproduct represents the main restriction for the crops irrigation in the municipality of Lins.
