Abstract:
Tolerance rough set model is an effective tool for attribute reduction in incomplete decision tables. In recent years, some incremental algorithms have been proposed to find reduct of dynamic incomplete decision tables in order to reduce computation time. However, they are classical filter algorithms, in which the classification accuracy of decision tables is computed after obtaining reduct. Therefore, the obtained reducts of these algorithms are not optimal on cardinality of reduct and classification accuracy. In this paper, we propose the incremental filter-wrapper algorithm IDS_IFW_AO to find one reduct of an incomplete desision table in case of adding multiple objects. The experimental results on some sample datasets show that the proposed filter-wrapper algorithm IDS_IFW_AO is more effective than the filter algorithm IARM-I [17] on classification accuracy and cardinality of reduct

Abstract:
As one of the key topics in the development of neighborhood rough set, attribute reduction has attracted extensive attentions because of its practicability and interpretability for dimension reduction or feature selection. Although the random sampling strategy has been introduced in attribute reduction to avoid overfitting, uncontrollable sampling may still affect the efficiency of search reduct. By utilizing inherent characteristics of each label, Multi-label learning with Label specIfic FeaTures (Lift) algorithm can improve the performance of mathematical modeling. Therefore, here, it is attempted to use Lift algorithm to guide the sampling for reduce the uncontrollability of sampling. In this paper, an attribute reduction algorithm based on Lift and random sampling called ARLRS is proposed, which aims to improve the efficiency of searching reduct. Firstly, Lift algorithm is used to choose the samples from the dataset as the members of the first group, then the reduct of the first group is calculated. Secondly, random sampling strategy is used to divide the rest of samples into groups which have symmetry structure. Finally, the reducts are calculated group-by-group, which is guided by the maintenance of the reducts’ classification performance. Comparing with other 5 attribute reduction strategies based on rough set theory over 17 University of California Irvine(UCI) datasets, experimental results show that: (1) ARLRS algorithm can significantly reduce the time consumption of searching reduct; (2) the reduct derived from ARLRS algorithm can provide satisfying performance in classification tasks.

Abstract:
Finding reductions from decision tables is one of the main objectives in information processing. Many studies focus on attribute reduct that reduces the number of columns in the decision table. The problem of finding all attribute reducts of consistent decision table is exponential in the number of attributes. In this paper, we aim at finding solutions for the problem of decision table reduction in polynomial time. More specifically, we deal with both the object reduct problem and the attribute reduct problem in consistent decision tables. We proved theoretically that our proposed methods for the two problems run in polynomial time. The proposed methods can be combined to significantly reduce the size of a consistent decision table both horizontally and vertically.

Abstract:
Abstract Reduct of decision systems is the topic that has been attracting the interest of many researchers in data mining and machine learning for more than two decades. So far, many algorithms for finding reduct of decision systems by rough set theory have been proposed. However, most of the proposed algorithms are heuristic algorithms that find one reduct with the best classification quality. The complete study of properties of reduct of decision systems is limited. In this paper, we discover equivalence properties of reduct of consistent decision systems related to a Sperner-system. As the result, the study of the family of reducts in a consistent decision system is the study of Sperner-systems.

This paper focuses on rough set theory which provides mathematical foundations of set-theoretical approximation for concepts, as well as reasoning about data. Also presented in this paper is the concept of relative reducts which is one of the most important notions for rule generation based on rough set theory. In this paper, from the viewpoint of approximation, the authors introduce an evaluation criterion for relative reducts using roughness of partitions that are constructed from relative reducts. The proposed criterion evaluates each relative reduct by the average of coverage of decision rules based on the relative reduct, which also corresponds to evaluate the roughness of partition constructed from the relative reduct,

Abstract:
Attribute reduction is a crucial problem in the process of data mining and knowledge discovery in big data. In incomplete decision systems, the model using tolerance rough set is fundamental to solve the problem by computing the redact to reduce the execution time. However, these proposals used the traditional filter approach so that the reduct was not optimal in the number of attributes and the accuracy of classification. The problem is critical in the dynamic incomplete decision systems which are more appropriate for real-world applications. Therefore, this paper proposes two novel incremental algorithms using the combination of filter and wrapper approach, namely IFWA_ADO and IFWA_DEO, respectively, for the dynamic incomplete decision systems. The IFWA_ADO computes reduct incrementally in cases of adding multiple objects while IFWA_DEO updates reduct when removing multiple objects. These algorithms are also verified on six data sets. Experimental results show that the filter-wrapper algorithms get higher performance than the other filter incremental algorithms.

Abstract:
Rough Sets Theory has opened new trends for the development of data analysis techniques. In this theory, the notion of reduct is very significant, but obtaining a reduct in a decision system is an expensive computing process although very important in data analysis and new discoveries. Because of this, it has been necessary to develop different variants to calculate reducts. The present work looks into the utility that offers Rough Sets in feature selection and a new method is presented with the purpose of calculate a good reduct. This new method consists of a greedy algorithm that uses heuristics to work out a good reduct in acceptable times. Experimental results obtained by using different data sets are presented.

Abstract:
The present research examined if mindfulness reduced negativity bias on measures of attitude formation and cognitive style, as a potential explanation for the beneficial effects of mindfulness on emotional disturbance. Two studies were conducted. Study One was correlational and found that trait mindfulness inversely correlated with measures of negative cognitive style, and that the latter partially mediated an inverse association between mindfulness and predisposition to depression and anxiety. Further, correlations between mindfulness and both positive attitude formation and optimism hinted at a potential positivity bias. Study Two extended these findings using a randomized experimental design comparing a mindfulness induction to an unfocused attention control condition. The mindfulness condition demonstrated a positivity bias in attitude formation and increased optimism compared to the control condition, but did not demonstrate bias in attitude generalization. Potential explanations and implications for emotional disturbance are discussed.

Abstract:
Presence is the quality of art that strikes a viewer; its energy is palpable. In every moment it is completely alive and in every moment after is alive once more. In 1967, critic, Michael Fried explained the importance of art’s ability to affect viewer continuously in this way and names the temporal affect of presentness as the most significant motivation of Minimalism; the essence of reduction is in this temporality. With much of the visual language of the Contemporary resting on the foundations of Minimalism, the temporal philosophy that is rooted in its vocabulary and aesthetics becomes an afterthought in the formalist discourse that Contemporary art is often framed by. To understand the reductive aesthetic comprehensively, the theory of temporal presence should be revisited. This paper is divided in two parts, the first will establish the philosophical foundations of Empty time and the second will apply concepts of Emptiness and Nothingness to reductive aesthetics. Crucial to presence are the temporal, spatial and experiential modes that are active in it. The meeting point of time and space, the current now, is where these encounters manifest but in the present moment, the movement of past-becoming-present-becoming-future occurs without our even feeling it. The ‘passing of time’ never actualises in our sensory experience, so we should cease to approach time in this way. Buddhist and Nietzschean philosophies raise concerns with this linear approach to time. To better understand the form of the present and the temporal language of reduction, I will examine the durationless model of time that shapes the sensation of experience. Buddhist, Śūnyatā and Nietzsche’s eternal return, will be examined to reconcile the disconnect between experiencing and the movement of time. The second component of the paper will examine the minimalist models of reduction, monochrome and repetition, against Fried’s essay. A clear lineage of presence becomes evident in the Contemporary’s thematic trends of ‘immaterial’ and ‘formless’, considering these examples demonstrate the legacy of reduction. To track the historical development of the minimal tradition, I will begin with Lucio Fontana (reduction) and move through to Yves Klein (monochrome) and finish with Lee Ufan (repetition). I intuitively apply the three aforementioned aesthetics to my creative practice and. Repetition plays a significant role; the demand for patience, will and perdurance is absorbing and, for me, the greatest teacher of time. The repeated gesture is an immersive exercise; it requires becoming absolutely attuned to time and Being. The mark is simultaneously the lingering anticipation of the next moment and mourning the passing of the last; it is a punctuation of Being. Time’s value is often treated as a commodity, so our desire to attain and hold it is overwhelming. It is in my practice that I can unlearn the ideas of time passing, running out, fading or eroding. The commitment to repeat infinitely eases the tension of chasing time.

Abstract:
Given two structures M and N on the same domain, we say that N is a reduct of M if all emptyset-definable relations of N are emptyset-definable in M. In this thesis, the reducts of the generic digraph, the Henson digraphs, the countable vector space over F_2 and of the linear order Q.2 are classified up to first-order interdefinability. These structures are aleph_zero-categorical, so classifying their reducts is equivalent to classifying the closed groups that lie in between the structures’ automorphism groups and the full symmetric group.

Abstract:
Businesses that fail to retain knowledgeable employees risk remaining competitive in the marketplace. Approximately 25 million people quit their jobs in 2016, overall. This single case study explored strategies business managers use to reduce employee turnover. The population for this study was 5 business managers from a business and technical personnel support organization in the information and solutions industry in the state of New Jersey who had experience with strategies to improve employee retention. The conceptual framework used in this study was systems theory. Data were collected from company archival documents and semistructured face-to-face interviews with 5 business managers. Moustakas' modified van Kaam method was used for data analysis. Member checking helped to ensure credibility and trustworthiness in the interpretation of interviewee responses. Three major themes emerged: workplace environment, safety, and training. Strategies ascertained in this study may be helpful for business managers who develop ways to reduce employee turnover. The implications for positive social change include retaining valuable employees in critical positions, reducing unemployment rates and unemployment compensation, and the potential to disencumber funds to support additional social services.

Full text
Abstract:
There has been a big input within the food industry to look at novel ways to achieve salt reduction in a food product without compromising the sensory profile and reducing the saltiness perception by consumers. The aim of this thesis was to understand if by optimising the sodium release from the food matrix, sodium reduction could be achieved without affecting the saltiness perceived by the consumers. In order to do that, three approaches were tri­alled: firstly, it was hypothesised that a reduction in the size of the salt crys­tal could accelerate dissolution in saliva and that by blending salt crystals of different sizes, sodium reduction could be achieved without compromising overall saltiness; secondly, it was hypothesised that the inclusion of plant- based polyphenols at subthreshold concentrations for astringency and bit­terness that precipitate salivary proteins could modify the rheological prop­erties of saliva and ultimately change saltiness perception; and finally it was hypothesised that sodium could be delivered in a hydrocolloid matrix and if this matrix is optimised for hydrateability, sodium may be more avail­able for perception. Results showed that a reduction of 25 % sodium can be achieved by using blends of salt crystals with different size without any loss of saltiness, as expressed by naive consumers. Subthreshold concentra­tions for astringency and bitterness for the four polyphenols used (tannic acid, gallic acid, rutin and EGCG) showed salivary protein precipitation, but had no impact on saltiness perception of solutions. Superthreshold concentrations for astringency and bitterness using the same polyphenols caused a decrease in saltiness perception of solutions. Out of the three different polymers (pullulan, chitosan and HPMC) studied to create orally dissolving films, HPMC showed the best film forming properties, and the fastest dissolution rate. In summary, optimisation of the food matrix and the salt crystal may offer a direct route to reducing sodium in the diet, and of the approaches evaluated the use of complex salt crystal size blends and the optimisation of sodium-biopolymer interaction are proposed as viable strategies for sodium reduction for the food industry.

Abstract:
In autumn 2017, an experiment was conducted for the reduction of carbon monoxide (CO) emissions commissioned by Holmen Paper Braviken, one of the world’s most production-efficient paper mills. Digitalization has increased in recent years, which has resulted in a decreased demand for graphic paper. The goal of finding cost-reducing solutions in the manufacturing process has been increased in Holmen Paper Braviken to meet the rising price pressure and strengthen competitiveness. Braviken consumes large quantities of steam in the paper machines and some of this steam is produced in the solid fuel boiler. The solid fuel boiler combusts bark, wood chips, and water treatment sludge. When adding sulfur-rich water treatment sludge to the fuel mix, it has been observed that CO levels decrease without increasing NOx levels. To control the amount of sulfur addition, it has been proposed that pure sulfur can be microdosed into the fuel mix. A previous short-term experiment was conducted in Braviken during autumn 2016 with a successful result. The present study was conducted with the aim of mapping the effects of sulfur addition to the solid fuel boiler in Braviken concerning CO emissions. The possibility to operate the plant and interaction with the water treatment sludge have also been investigated. The study was performed through the construction of a microdosing system and a long-term attempt of sulfur addition. The result shows that the optimal sulfur concentration of Braviken’s solid fuel boiler for reducing CO emissions is 6 kg/h S (1.03 kg S/ton C). The interaction between elemental sulfur with the sulfur-rich water treatment sludge is complex, but with sulfur dosage a reduction of 42% CO can be achieved. NOx levels have not shown any change on the addition of sulfur. The study shows that CO emissions are at a more stable level with sulfur dosing. The result becomes difficult to analyze because the parameters varied. The effects of parameters should be investigated with the recommendation to perform a more prolonged experiment on sulfur addition.<br>Under hösten 2017 genomfördes ett experiment med dosering av svavel för reduktion av kolmonoxidutsläpp(CO) i uppdrag av Holmen Paper Braviken. Digitaliseringen har under de senaste åren ökat vilket har medföljt att efterfrågan på grafiskt papper har sjunkit. För att möta den ökande prispressen och stärka konkurrenskraften har målet att hitta kostnadssänkningar i tillverkningsprocessen ökats i Holmen Paper Braviken. Braviken förbrukar stora mängder ånga i pappersmaskinerna och en del av denna ånga produceras i brukets fastbränslepanna. I fastbränslepannan förbränns bark, träflis samt vattenreningsslam. Vid tillsatser av svavelrikt vattenreningsslam till bränslemixen har det observerats att CO nivåerna sjunker utan att NOx nivåerna ökar. För att kunna reglera mängden svaveltillsatser har det förslagits att rent svavel kan mikrodoseras till bränslemixen. Ett tidigare försök har gjorts i Braviken under hösten 2016 med ett lyckat resultat. Denna studie har genomförts med målet att kartlägga effekterna av svaveltillsats till Bravikens fastbränslepanna med avseende på CO utsläpp. Körbarheten och samspelet med det svavelrika vattenreningsslammet har även det undersökts. Studien har genomförts genom konstruktion av tillsatsanordning samt långtidsförsök av svaveltillsats. Resultatet visar att den optimala svavelkoncentrationen för Bravikens fastbränslepanna för reduktion av CO utsläpp är 6 kg/h S (1.03 kg S/ton C). Samspelet mellan rent svavel med det svavelrika vattenreningsslammet är komplext, men med svaveldosering kan en reduktion av 42% CO uppnås. NOx nivåerna har inte påvisat någon förändring vid tillsats av svavel. Studien visar att CO utsläppen håller sig till en stabilare nivå vid svaveldosering. På grund av att ett flertal parametrar varieras är resultatet svår att analysera. Parametrarnas effekter bör undersökas med rekommendation att utföra ett längre experiment av svaveltillsats.

Abstract:
O Coletivo Cultural das Casinha representa uma iniciativa colaborativa que visa a mobilização e capacitação de mulheres maiores de 18 anos, em situação de vulnerabilidade, residentes no Conjunto Habitacional Deputado Jamil Dualibi e/ou Zona Leste de Tupã. Esta empreitada é resultado da convergência de esforços da comunidade acadêmica local, organizações da sociedade civil e instituições governamentais, com o propósito central de estabelecer um Coletivo de Cultura periférica tupãense. Isso implica na criação de uma estrutura formal, incluindo um conselho, direção e um contrato de gestão, com vistas à fundação de uma Organização Social que ocupará as instalações do antigo postinho de saúde do Jamil Dualibi. As atividades de extensão que serão executadas concentram-se prioritariamente em mulheres em situação de vulnerabilidade e seus filhos matriculados nas escolas públicas de ensino fundamental II e médio. A equipe envolvida opera em cinco frentes de atuação: formação social, legal e institucional do Coletivo, comunicação e disseminação de informações, articulação com outras organizações sociais e instituições públicas, ações educacionais para abordar desafios de aprendizagem e formação contínua destinada a servidores, professores, técnicos, estudantes e egressos envolvidos no projeto.
