RESUMO - As perdas na colheita podem estar relacionadas tanto a colhedora, como também a fatores ligados a cultura como: mau preparo do solo, densidade de plantas, inadequação da época de semeadura são alguns deles. O presente estudo objetivou determinar a influência da velocidade de semeadura no processo de colheita mecanizada de milho, por meio do controle de qualidade do processo. O experimento foi conduzido em Latossolo Vermelho, textura argilosa e relevo suave ondulado. O delineamento foi baseado na óptica do Controle Estatístico de ProcessoCEP, onde os dados foram coletados em pontos aleatórios em função do tempo. Os indicadores de qualidade avaliados foram divididos em parâmetros de semeadura (população de plantas e distribuição longitudinal de plântulas); e de colheita (Perdas de grãos e distribuição de palha) em função de seis velocidades de deslocamento (aproximadamente 2,0; 4,0; 6,0; 9,0; 10,0 e 12,0 Km.h-1). Os dados foram submetidos a análise descritiva para análise do comportamento. Como ferramentas do controle estatístico de processo utilizou-se, run charts ou gráfico sequencial e carta de controle de valores individuais para análise da qualidade do processo. A maior velocidade (V6) apresentou a maior variabilidade dos dados para todas as variáveis. A operação da colheita mecanizada de milho foi influenciada por fatores extrínsecos e intrínsecos a ela.Palavras-chave: Controle estatístico de processo, espaçamentos normais, perdas, população de plantas.QUALITY IN MECHANIZED HARVEST OF CORN SOWN IN DIFFERENT SPEEDSABSTRACT - The harvest losses may be associated to harvester as well as factors related to cultivation such as poor soil preparation, plant density, unsuitable sowing time. This study aimed to determine the effect of speed sowing in the mechanized harvest of corn, through the control of the quality of the process. The experiment was conducted in a clayey Oxisol and undulate relief. The design was based on the optics of the Statistical Process Control SPC, and the data were collected at random points in function of time. The quality indicators evaluated were divided into sowing parameters (plant population and longitudinal distribution of seedlings) and harvesting (loss of grain and straw distribution) in function of six displacement speeds (approximately 2.0, 4.0, 6.0, 9.0, 10.0 and 12.0 Km.h-1). The data were submitted to descriptive analysis for behavior analysis. As tools for the statistical control of the process, run charts or sequential graph were used, and control chart of individual values for analysis of the quality of the process. The highest speed (V6) showed the highest variability of the data for all variables.

Devido aos problemas ambientais que vem ocorrendo, as empresas passaram a sofrer uma forte pressão por parte dos governos e até mesmo pela sociedade para que invistam em mecanismos de produção menos impactantes ao meio ambiente. Nesse contexto, a certificação por meio da ISO 14001 surge como uma oportunidade para as empresas, além de cumprirem as exigências legais, conquistarem um mercado consumidor que cada vez mais se preocupa com as questões ambientais. Desse modo a fim de verificar a percepção ambiental e o conhecimento dos consumidores a respeito da preocupação ambiental das empresas, em especial os estudantes da Universidade Federal de Mato Grosso, e a possível influência na sua decisão de compra foi realizado uma pesquisa sob a forma de questionários. Foram obtidas 135 respostas em que foram observadas que a partir da percepção ambiental apresentada pelos estudantes de maneira geral, a maioria destes se mostrou preocupado com as questões ambientais e a favor de empresas fabricantes de produtos que em sua manufatura minimizem o impacto ao meio ambiente. Porém, de acordo com as respostas observa-se que ainda não é significante o conhecimento a respeito de sistemas de gestão ambiental adotados, em especial a ISO 14001.

RESUMO O mundo é movido pela busca incessante de saciar suas necessidades. O ser humano é o único animal que não se adapta ao meio ambiente e sim o adapta a sua rotina e atividades. Como prova disso está a globalização provando que a evolução mecânica, eletrônica e social está cada dia mais forte e inserida na cultura mundial. Essa inserção está ligada principalmente ao desenvolvimento socioeconômico. Porém, em uma sociedade tão desenvolvida ainda encontra-se desigualdades e deficiências, principalmente quando se refere à educação, orientação e cultura de segurança no trabalho. Apesar de muitas campanhas estarem surgindo, o reconhecimento da importância da conduta e de práticas de segurança em muitas áreas ainda precisa amadurecer os seus objetivos e métodos, para atingir a realização das diversas atividades sem danos para saúde e integridade do colaborador. O presente trabalho consiste em uma análise realizada voltada para área de limpeza, conservação e organização pública; em específico a atividade de coleta domiciliar de lixo, que atualmente não é assunto em evidência, porém é necessária e indispensável para uma das necessidades naturais humana: a de limpeza, e é justo no domicilio o lugar onde a população não tem interesse em separação de resíduos, menos ainda em identificação dos mesmos. Por esse motivo além de apontar riscos potenciais, o trabalho visa propor medidas preventivas e de controle para os riscos analisado nos postos de trabalho da atividade de coleta de lixo domiciliar.

Published: October 2017

Este trabalho busca analisar a água bruta e o lodo produzido na Estação de Tratamento de Água (ETA), situada na cidade de Várzea Grande, Mato Grosso, visando a correta destinação deste material, seja no meio ambiente, seja por meio de alternativas como o seu reaproveitamento na própria estação, visando reduzir o desperdício de água, sobretudo na época de secas da região, período em que o estudo ocorreu. Estudou-se os parâmetros físico-químicos (potencial hidrogeniônico (pH), cor, turbidez, demanda química de oxigênio (DQO), teor de sólidos sedimentáveis, totais, fixos e voláteis). Verificou-se que o resíduo da estação lançado em corpos hídricos não está de acordo os parâmetros definidos pela Resolução n.º 430/2011 do Conselho Nacional do Meio Ambiente (CONAMA) (os teores de sólidos sedimentáveis estão acima do permitido). No entanto, há a possibilidade de dar uma destinação adequada a esse material por meio do reaproveitamento da água de lavagem dos filtros (teor de sólidos de 0,1%) pela própria estação.
Sistema de Cogeração entre uma Usina de Dessalinização e um Reator Nuclear a Fusão
Authors: Salles Sinesio , Moreira Vanessa Madrona
Published: October 2017

A solução que será analisada é de um sistema de cogeração de uma usina de dessalinização de água do mar com um reator de fusão, onde se busca estabelecer o lay-out da instalação, os sistemas de interface entre as duas usinas, os parâmetros de sincronismo, e o controle dos riscos de falha. Os volumes de água doce e salgada no planeta Terra são respectivamente de 2,5% para 97,5%. Para o volume de água doce, apenas 1% se encontra disponível na superfície, o restante está no subsolo ou nas calotas polares. Os sinais de falta de energia e de falta de água potável já começam a aparecer. Atualmente 20% da população mundial não tem acesso à água potável. O aumento demográfico somado ao aumento da demanda per capita trará uma tendência de crescimento cada vez maior destas duas crises. A previsão para as próximas décadas é de duplicação das demandas, e fica cada vez mais óbvio que a solução não poderá ser apenas dobrar o atual modelo de produção. Novas técnicas deverão ser criadas para que surjam novos padrões de atendimento destas demandas.
La ciudad narrada: Revuelta y semántica del conflicto urbano
Authors: Diz Carlos
Published: October 2017

A partir del relato de un episodio concreto de mi trabajo de campo etnográfico, desarrollado en Copenhague en 2009, trataremos de analizar el papel de la ciudad en los recientes movimientos sociales. Desde el final del movimiento antiglobalización a las revueltas urbanas de la segunda década del siglo XXI, la ciudad se ha convertido en un objeto central del debate político, social y epistemológico. Un objeto central de los discursos y las narrativas contemporáneas. Describiendo la revuelta y el conflicto urbano desde un punto de vista simbólico y material, pero también semántico, atenderemos a una semántica del conflicto urbano que nos revela una ciudad narrada compuesta de múltiples voces y líneas argumentales. El conflicto social, inherente a la vida urbana y a la cotidianidad del activismo y los movimientos sociales, se analiza aquí desde el punto de vista de los imaginarios, las historias y las narraciones. Contraponiendo los discursos de las élites a los discursos activistas, se observarán también los procesos de marketización y empresarialismo urbano así como la retórica de la ciudad marca y la ciudad creativa.

Published: October 2017

O objetivo deste artigo é analisar a implantação das escolas de instrução primárias na Colônia Agrícola de Benevides da província do Pará (1861-1881). Para atingir tal propósito metodologicamente nos apoiamos no tipo de pesquisa documental, que inclui relatórios dos diretores da instrução pública, relatórios dos presidentes da província do Pará, legislação educacional e os jornais da época como o “Diário do Gram Pará” e “O Liberal”. Essas fontes foram pesquisadas na Biblioteca Pública do Pará Arthur Viana, Arquivo Público do Estado do Pará, Instituto Histórico e Geográfico Brasileiro e na Biblioteca Nacional. Para compreender as escolas primárias da colônia agrícola de Benevides na província do Pará na segunda metade do século XIX, nos apoiamos em teóricos da Nova História Cultural como Burke (2005), Chartier (2002), Julia (2001). As escolas primárias da colônia de Benevides funcionavam nos horários da manhã e da tarde para atender os filhos e filhas dos colonos estrangeiros e brasileiros com idades entre 6 e 15 anos, além de filhos de escravas alforriadas e crianças indígenas. No período da noite atendia os colonos adultos que desejavam aprender as primeiras letras.
História da institucionalização da educação infantil: dos espaços de assistência à obrigatoriedade de ensino (1875-2013)
Authors: Filipim Priscila Viviane de Souza , Rossi Ednéia Regina , Rodrigues Elaine
Published: October 2017

Neste artigo, a intenção é abordar a história da institucionalização da educação infantil no Brasil, tendo como fonte a legislação brasileira e pesquisas realizadas sobre o tema. As nomenclaturas existentes para as instituições deste nível encerram, em si, conceitos e finalidades distintos e estão atreladas aos contextos históricos de seus países de origem.  Ao longo da idade moderna, criou-se um conceito de infância e o entendimento da importância de estímulos para o seu desenvolvimento. Essa mentalidade impulsiona iniciativas de criação de espaços exclusivos de formação e a compreensão do direito da criança à educação. Essa visão é contemplada no texto da Constituição Federal do Brasil de 1988 e no Estatuto da criança e do adolescente – Lei nº 8.069/90. Assim, como direito, a Lei de Diretrizes e Bases da Educação Nacional (LDBEN, nº 9.394/96) insere a educação infantil no sistema de educação nacional, sendo a obrigatoriedade de parte deste nível instituída pela Lei 12.796 de 2013.  Correlatas a essas mudanças, as Diretrizes Curriculares Nacionais para a Educação Infantil propagam a ideia educacional de indissociabilidade do cuidar, do educar e do brincar.

Supply Chain Management (SCM) includes management of materials, products, services, information and financial flows which network of consisting suppliers, manufacturers, logistics service companies, and clients. The individual elements of this chain with coordination and integration of each element to perform themselves ensure successful of SCM. Information technology has a very important role in activities for coordination and integration of supply chain. Acceleration of sharing information, simplification and increasing of reliability provide effective use of time in logistics companies, cost savings like effective management ways. In this prepared study which taking into account the positive impact on supply chain of information technologies, it was investigated on the effectiveness of sharing information of supply chain by examining infrastructure of the information technology, ranging from the production of raw materials to the end user in SCM. The results of the analyses by using the structural equation model indicate that the use of information technology in supply chain management enhances the relationship between buyer-supplier; the enhancement of such relationship improves the quality, safety, and flexibility of products and reduces the cost of products; as a result, it increases firm performance.
Customer Satisfaction in Participation Banks

Published: October 2017

Interest income is considered as forbidden in Islam. Therefore, in Turkey, conservatives generally don’t prefer general banking and by this way funds can’t be used in economic system. So saving deficit can’t be solved in country and saving of people depreciates against inflation. Participation banks which work according to Islamic rules are set up to bring these funds to economy. Participation banking operates in more than 60 countries today and conservatives generally prefer to work with because they are working to principles of profit instead of interest. To attract and persuade more people, at first participation banks should satisfy their customers. In our study we aim to measure customer satisfaction in participation banks in Kastamonu and to reveal the differences between demographic groups. To this aim we conducted a questionnaire to customers of participation banks in Kastamonu.

Published: October 2017

The group ranch system is one of the best land ownership and livestock production strategies in the dry lands of the world where the potential for rain-fed agriculture is limited. This has resulted in numerous studies on the establishment of group ranches, their dissolution and coping strategies but with less focus on the sustainability of the group ranches. It is against this background that this study investigated organizational factors influencing choice of sustainability strategies adopted by group ranches in Samburu County; Kenya. The study adopted a descriptive survey research design employing use of Questionnaires, Key Informant Interviews, Focus Group Discussions and observation as primary data collection methods. The study used content validity and Cronbach’s alpha methods to measure validity and reliability of the research instruments, respectively. The target population for the study was the 16,611 registered members in 38 group ranches spread out in the County. The study sampled twelve group ranches with approximately 5,643 members from which 374 respondents were systematically sampled. Purposive sampling was used to select Key Informants and the participants in the Focus Group Discussions. The investigation employed Multi-linear Regression to analyse organizational factors influencing choice of sustainability strategies adopted by group ranches in Samburu County while the Analysis of Variance (ANOVA) was used to test the hypothesis which stated that there was no significant influence of organizational factors on choice of sustainability strategies adopted by group ranches in Samburu County, Kenya. The p-value of 0.00 was obtained, indicating that organizational factors significantly influenced choice of sustainability strategies adopted by group ranches in the County. Overall, past experiences was the predominating organizational factor with a regression coefficient of 0.432 while past strategies had the least influence on choice of sustainability strategies adopted by group ranches in Samburu County, with a regression coefficient of 0.110. The study recommended integration of organizational factors in formulating policies for sustainability of group ranches.

Published: October 2017

Recent findings show that preferences for food items can be modified without external-reinforcements using the cue-approach task. In the task, the mere association of food item images with a neutral auditory cue and a speeded button press, resulted in enhanced preferences for the associated stimuli. Here, in a series of 10 independent samples with a total of 255 participants, we show we can enhance preferences using this non-reinforced method for faces, fractals and affective images as well as snack foods, using auditory, visual and even aversive cues. This change was highly durable in follow-up sessions performed one to six months after training. Preferences were successfully enhanced for all conditions, except for negative valence items. These findings promote our understanding of non-reinforced change, suggest a boundary condition for the effect and lay the foundation for development of novel applications.

Authors: Pramanik Surapati , Dalapati Shyamal , Alam Shariful , Roy Tapan Kumar
Published: October 2017

Neutrosophic cubic set is the hybridization of the concept of neutrosophic set and interval neutrosophic set. Neutrosophic cubic set has the capacity to express the hybrid information of both the interval neutrosophic set and the single valued neutrosophic set simultaneously. As newly defined, little research on the operations and applications of neutrosophic cubic sets appear in the current literature. In the present paper we propose the score, accuracy functions for neutrosophic cubic sets and prove their basic properties. We firstly develop TODIM method to solve multi attribute group decision making in neutrosophic cubic set environment, which we call NC-TODIM. Also, we solve a MAGDM problem using the proposed NC-TODIM method to show the applicability and effectiveness of the developed method. We also conduct sensitivity analysis to show the impact of ranking order of the alternatives for different values of attenuation factor of losses for multi-attribute group decision making problem.
Dietary Magnesium May Be Protective for Aging of Bone and Skeletal Muscle in Middle and Younger Older Age Men and Women: Cross-Sectional Findings from the UK Biobank Cohort
Authors: Welch Ailsa A. , Skinner Jane , Hickson Mary
Published: October 2017

Although fragility fractures, osteoporosis, sarcopenia and frailty are becoming more prevalent in our aging society the treatment options are limited and preventative strategies are needed. Despite magnesium being integral bone and muscle physiology the relationship between dietary magnesium and skeletal muscle and bone health has not been investigated concurrently before. We analysed cross-sectional associations between dietary magnesium and skeletal muscle mass (as fat free mass – FFM), grip strength and bone density (BMD) in 156,575 men and women aged 39-72 years from the UK Biobank cohort. FFM was measured with bioelectrical impedance and expressed as the percentage of body weight (FFM%) or divided by body mass index (FFMBMI). Adjusted mean grip strength, FFM%, FFMBMI, and BMD were calculated according quintiles of dietary magnesium, correcting for covariates. Significant inter-quintile differences across intakes of magnesium existed in men and women respectively of 1.1% and 2.4% for grip strength, 3.0% and 3.6% for FFM%, 5.1% and 5.5% for FFMBMI, and 2.9% and 0.9% for BMD. These associations are as great or greater than annual measured losses of these musculoskeletal outcomes indicating potential clinical significance. Our study suggests that dietary magnesium may play a role in musculoskeletal health and have relevance for population prevention strategies for sarcopenia, osteoporosis and fractures.

Published: October 2017

While referral-level medicine is important in the veterinary curriculum, students also need a solid base knowledge of clinically relevant routine surgery and diagnostic skills. Veterinary hospitals must maintain a steady caseload that provides wellness cases and commonly encountered conditions. Shelter Medicine programs can create the opportunities to meet these challenges. Students can gain quantifiable surgical experience in spay/neuter with measured growth in surgical efficiency and competency while providing needed community service for animal shelters. Students can directly interact with shelter animals by performing examinations, diagnostic testing, and development of treatment protocols and recommendations for commonly encountered problems. Furthermore, students can obtain a working knowledge of biosecurity on a population level to minimize risk of infectious diseases spreading to healthy populations.
On Subcool Control in Steam-Assisted-Gravity-Drainage Producers— Part I: Stability Envelopes
Authors: Irani Mazda
Published: October 2017

Steam-assisted-gravity-drainage (SAGD) industry experience indicates that the majority of producer workovers occur because of liners or electrical submersible pumps (ESPs), and both failures appear to result from inefficient “steam-trap control.” Thermodynamic steam-trap control, also termed “subcool control,” is a typical operation strategy for most SAGD wells. Simply, subcool (or reservoir subcool vs. pump subcool) is the temperature difference between the steam chamber (or injected steam) and the produced fluid. The main objective is to keep subcool higher than a set value that varies between 0 to 40° and even higher values.

This study presents a method to calculate the liquid-pool level from the temperature profile in observation wells, and liquid-pool shrinkage as a function of time. Unfortunately, it is not practical to monitor the liquid level by having observation wells for every SAGD well pair. For this reason, the algebraic equation for liquid-pool depletion on the basis of wellbore-drawdown, subcool, and emulsion productivity is generated. By use of this equation, the envelopes are suggested to differentiate three different regimes: “stable production,” “liquid-pool depletion,” and “steam-breakthrough limit.” Gas lift operations such as the MacKay River thermal project suggested that envelopes for constant wellbore drawdown are not practical. Therefore, the steam-breakthrough limit is defined for constant rate, which is more consistent in gas lift operations. In this study, the steam-breakthrough limit is validated for operation data from the MacKay River. This study provides a new insight into how factors such as production rate and wellbore drawdown can compromise subcool control and cause steam breakthrough, and how liquid-pool depletion may result in uncontrolled steam coning at long time.

As a part of this study, a minimum-subcool concept (or target reservoir subcool) is presented as a function of skin and pressure drawdown. It is shown that the minimum subcool is highly dependent on the maturity of steam-chamber and underburden heat loss especially for zero-skin producers. The results of this work emphasize that the target subcool on the producer should increase slightly with chamber maturity, considering that the skin is nonzero for most SAGD producers.
Acid production potentials of massive sulfide minerals and lead–zinc mine tailings: a medium-term study
Authors: Çelebi Emin Ender , Öncel Mehmet Salim , Kobya Mehmet
Published: October 2017

Weathering of sulfide minerals is a principal source of acid generation. To determine acid-forming potentials of sulfide-bearing materials, two basic approaches named static and kinetic tests are available. Static tests are short-term, and easily undertaken within a few days and in a laboratory. In contrast, kinetic tests are long-term procedures and mostly carried out on site. In this study, experiments were conducted over a medium-term period of 2 months, not as short as static tests and also not as long as kinetic tests. As a result, pH and electrical conductivity oscillations as a function of time, acid-forming potentials and elemental contents of synthetically prepared rainwater leachates of massive sulfides and sulfide-bearing lead–zinc tailings from abandoned and currently used deposition areas have been determined. Although the lowest final pH of 2.70 was obtained in massive pyrite leachate, massive chalcopyrite leachate showed the highest titrable acidity of 1.764 g H2SO4/L. On the other hand, a composite of currently deposited mine tailings showed no acidic characteristic with a final pH of 7.77. The composite abandoned mine tailing leachate had a final pH of 6.70, close to the final pH of massive galena and sphalerite leachates, and produced a slight titrable acidity of 0.130 g H2SO4/L.

Published: October 2017

"Eva muda la piel…" aproximó a la construcción de un abordaje terapéutico que propicia que las personas re-encanten su vida. A través del trabajo con un diario de sueños y sentimientos y técnicas artísticas-creativas, profundizó en el concepto de culpa patriarcal, así como en actitudes, prácticas, circunstancias sociales y manifestaciones de la psique profunda que propician la asunción responsable de un proyecto de vida. Se hizo manifiesto que el ser mujer continúa siendo vivido desde la dominación masculina y que la imposibilidad de cumplir con las normativas patriarcales aprendidas y aceptadas, desarrolla sentires de culpa a lo interno de las mujeres, haciendo que no se consideren capaces de realizar sus sueños ni merecedoras de que sus deseos se cumplan. Las vías de la redención verdadera se nos presentan en un doble sentido. Por una parte, a través del diálogo interior y, por otra, el desarrollo de una nueva relación con el mundo que nos rodea, a través de mediaciones simbólicas: gesto, dibujo, danza, poesía, que posibilitan hacer de nuestros actos cotidianos, verdaderas obras de arte.

Banking sector plays an important role in the economic sustainable development. In the context of the financial crisis and the introduction of new international standards, in accordance with the "Basel III" agreement, the requirements of Central Bank of the Russian Federation to it have increased. Credit policy is an important tool that reflects the efficiency of a commercial bank in the context of risk and credit optimization. It performs the following functions: setting goal and tasks, information support, etc. All this actualizes the issues of research and the forming an optimal credit policy. The article describes the model of formation and mechanism of implementing the credit policy, based on the delineation of structural elements, taking into account their functional purpose. The authors formulate the main system tasks to achieve this goal and develop the theoretical basis and methodology for the activities of the commercial banks in the field under study. The systematizing the theoretical foundations and the specific features of the formation of credit policy at the macro and micro levels according to the most important parameters, and substantiation of the organizational and methodological support for the implementation of lending processes are the main among these tasks. Scientific works of domestic and foreign scientists in the field of financial, credit, banking system is the ground of the research. Theoretical methods, such as synthesis, analysis, deduction and induction, as well as a logical, systemic approach, a comparison method have allowed researches to obtain the conclusions. Based on the patterns found in the study, the authors substantiate the close interconnection and interdependence of the elements participating in the process of forming the bank's policy in the area of lending considering their functional purpose. It is suggested to use the following elements in the for-mation of the structural model: conceptual, procedural, administrative and security elements. The features of the credit policy and proposals for its implementation, identified and formulated by the authors, allow increasing the efficiency of the commercial bank.
Aki (információ)szegény, az a legszegényebb? Az információs szegénység megjelenési formái
Authors: Csótó Mihály
Published: October 2017

A tanulmány áttekinti az információs szegénység fogalmának kialakulását, valamint jelentéstartalmának fejlődéstörténetét, az információs szegénység értelmezési keretének és hatókörének folyamatos bővülését az 1970-es évektől elindulva. A különböző megközelítések és elemzések alapján elmondható, hogy az információs szegénység egy olyan állapot, amelyet jelentősen meghatározhat ugyan a gazdasági értelemben vett szegénység, vagy a különböző információs technológiák hatékony használata, de legfőbb jellemzőjeként a cselekvésképtelenség, az egyén által a mindennapi élet kihívásaira adott válaszok elmaradása azonosítható.

Are the poorest the information poor? The various forms of information poverty

This study looks at the development of the concept of information poverty, the evolution of its meaning and the continuous expansion of the understanding and the scope of this term, starting from the 1970s. Based on different approaches and analyses, information poverty can be identified as a state, whose main feature (which can, however, be significantly influenced by economic poverty or the effective use of different information technologies) is the inability to act: the failure of individuals to respond to the challenges in their everyday lives.
Spatial and urban planning in Serbia: A look through the lens of deliberative approach
Authors: Peric Ana , Miljus Milutin
Published: October 2017

In planning, the deliberative process is most commonly present in the form of
a structured public discussion. The main idea behind such an approach is to
improve communication among different participants by informing them about a
local problem before any stakeholders? preference is adopted, agreement
reached and, finally, the problem solved. With the help of a mediator, an
independent third party, the participants are considered equal, rational and
free to give their opinion. Such a deliberative approach is an integral part
of most planning procedures in developed countries. However, the enhancement
of the planning process in the post-socialist context is delayed due to
institutional rigidities, public mistrust towards the initiators of spatial
development, and the lack of mediation procedures in the planning process.
Previous features are also specific to Serbia, as a transitional state,
which, nevertheless, experienced a somewhat different social context in
comparison to other Eastern Bloc countries during the second half of the
previous century. To understand the contemporary situation better, the paper
provides an overview of spatial and urban planning in Serbia since the Second
World War, observed from the deliberative stand, in an attempt to define the
basic guidelines for the transformation of the planning approach in Serbia.
Offsetting Misstatements: The Effect of Misstatement Distribution, Quantitative Materiality, and Client Pressure on Auditors' Judgments
Authors: Messier William F. , Schmidt Martin
Published: October 2017

This paper reports on the first experimental study to examine how materiality and client pressure affect auditors' judgments of two detected misstatements that have offsetting effects on the client's income. One hundred forty-three experienced German auditors completed a case that varied the misstatement distribution (same or different accounts), the presence or absence of client pressure, and quantitative materiality of the misstatements nested in the client pressure condition (net amount less than or greater than performance materiality). The results show: First, the distribution of the misstatements and client pressure interact. The proportion of auditors who require the client to fully adjust both misstatements is highest when the offsetting misstatements are in two different accounts and there is no client pressure. Second, misstatement distribution interacts with quantitative materiality. The proportion of auditors who deny the bonus when facing client pressure is highest when the level of materiality is greater than performance materiality and the misstatement distribution is in different accounts. Third, audit experience appears to play a role in the auditors' judgments. While more experienced auditors are more likely to fully correct the misstatements when there is no client pressure, they are also more likely to waive the misstatements when faced with client pressure. Additional experimentation confirms these findings. These results have important implications for researchers, practitioners, regulators, and standard setters.

Determinants of Financial Managers' Willingness to Engage in Unethical Pro-Organizational Behavior
Authors: Mahlendorf Matthias D. , Matějka Michal , Weber Jürgen
Published: October 2017

We examine how financial managers' willingness to engage in unethical pro-organizational behavior depends on various individual and organizational characteristics. Using survey data from 253 respondents we find that unethical pro-organizational behavior is lower when financial managers are close to retirement and when they work in high-growth or in publicly listed companies. We also find that it is positively associated with financial managers' organizational identification and with their bonuses contingent on financial performance targets but not with bonuses contingent on nonfinancial targets or subjective evaluations. We rely on a follow-up survey to reestimate the latter effects after controlling for unobserved individual heterogeneity in a changes model and find consistent results. Finally, we use another follow-up survey to compare our measure of the willingness to engage in unethical pro-organizational behavior to proxies for earnings management used in prior literature.
Evidence That Differences in Fructosamine-3-Kinase Activity May Be Associated With the Glycation Gap in Human Diabetes

The phenomenon of a discrepancy between glycated hemoglobin levels and other indicators of average glycemia may be due to many factors but can be measured as the glycation gap (GGap). This GGap is associated with differences in complications in patients with diabetes and may possibly be explained by dissimilarities in deglycation in turn leading to altered production of advanced glycation end products (AGEs). We hypothesized that variations in the level of the deglycating enzyme fructosamine-3-kinase (FN3K) might be associated with the GGap. We measured erythrocyte FN3K concentrations and enzyme activity in a population dichotomized for a large positive or negative GGap. FN3K protein was higher and we found a striking threefold greater activity (323%) at any given FN3K protein level in the erythrocytes of the negative-GGap group compared with the positive-GGap group. This was associated with lower AGE levels in the negative-GGap group (79%), lower proinflammatory adipokines (leptin-to-adiponectin ratio) (73%), and much lower prothrombotic PAI-1 levels (19%). We conclude that FN3K may play a key role in the GGap and thus diabetes complications such that FN3K may be a potential predictor of the risk of diabetes complications. Pharmacological modifications of its activity may provide a novel approach to their prevention.
