Homogenized Variability of Radiosonde-Derived Atmospheric Boundary Layer Height over the Global Land Surface from 1973 to 2014
Authors: Wang Xiaoyan , Wang Kaicun
Published: July 2016

Boundary layer height (BLH) significantly impacts near-surface air quality, and its determination is important for climate change studies. Integrated Global Radiosonde Archive data from 1973 to 2014 were used to estimate the long-term variability of the BLH based on profiles of potential temperature, relative humidity, and atmospheric refractivity. However, this study found that there was an obvious inhomogeneity in the radiosonde-derived BLH time series because of the presence of discontinuities in the raw radiosonde dataset. The penalized maximal F test and quantile-matching adjustment were used to detect the changepoints and to adjust the raw BLH series. The most significant inhomogeneity of the BLH time series was found over the United States from 1986 to 1992, which was mainly due to progress made in sonde models and processing procedures. The homogenization did not obviously change the magnitude of the daytime convective BLH (CBLH) tendency, but it improved the statistical significance of its linear trend. The trend of nighttime stable BLH (SBLH) is more dependent on the homogenization because the magnitude of SBLH is small, and SBLH is sensitive to the observational biases. The global daytime CBLH increased by about 1.6% decade−1 before and after homogenization from 1973 to 2014, and the nighttime homogenized SBLH decreased by −4.2% decade−1 compared to a decrease of −7.1% decade−1 based on the raw series. Regionally, the daytime CBLH increased by 2.8%, 0.9%, 1.6%, and 2.7% decade−1 and the nighttime SBLH decreased significantly by −2.7%, −6.9%, −7.7%, and −3.5% decade−1 over Europe, the United States, Japan, and Australia, respectively.

Published: July 2016

The aim of this study was to investigate the anti-hyperglycemic activity and mechanism of formononetin in alloxan-induced type 1 diabetic mice by determining its effect on some diabetes-related indices as described below. Body weight, fasting blood glucose, hepatic glycogen, serum insulin, and serum glucagon were determined by electronic scales, glucometer, and ELISA kits. Fas, Caspase-3, pancreatic and duodenal homeobox-1 , insulin receptor substrate 2, glucokinase and glucose transporter 2, mRNA and proteins levels in pancreas tissue, and glucokinase and glucose-6-phosphatase mRNA, and proteins levels in liver tissue were detected by fluorogenic quantitative-polymerase chain reaction and Western blot assays. The results indicated that formononetin (5, 10, and 20 mg/kg; oral administration) reversed the alloxan-induced increase of some indices (fasting blood glucose level and Fas and Caspase-3 mRNA and proteins levels in pancreas tissue) and reduction of some indices (body weight gain, oral glucose tolerance, insulin activity, hepatic glycogen level, pancreatic and duodenal homeobox-1, insulin receptor substrate 2, glucokinase and glucose transporter 2, mRNA and proteins levels in pancreas tissue, and glucokinase mRNA and protein levels in liver tissue). The glucagon level and glucose-6-phosphatase mRNA and protein levels in liver tissue were not affected by the drugs administration. In conclusion, formononetin exhibited anti-hyperglycemic activity in alloxan-induced type 1 diabetic mice by inhibiting islet B cell apoptosis and promoting islet B cell regeneration, insulin secretion, hepatic glycogen synthesis, and hepatic glycolysis.
Proton-Transfer Dynamics in Protonated Benzene
Authors: Kuroki Ayaka , Ushiyama Hiroshi , Yamashita Koichi
Published: July 2016

The proton-transfer reaction mechanism in protonated benzene was examined using ab initio molecular dynamics, paying special attention to cooperative motions. We first examined the lifetime of each stable state of protonated benzene, taken as equal to the time lag between proton-transfer reactions. The theoretically obtained lifetime distribution shows non-statistical behavior, since it contains a large number of short lifetime trajectories. By analyzing the nature of these short trajectories, we found that a transferred proton can be trapped between two carbon atoms. Because carbon atoms adjacent to the transferred proton will change their hybridization during proton-transfer reactions, and since it requires tens of femtoseconds to reform hybrid orbitals, the proton will oscillate between the two carbon atoms without bonding to either. We refer to this trapped state as a “dynamically stable trapped state” and consider that such states may appear in many types of chemical reactions.
Where are the female science professors? A personal perspective
Authors: Kamerlin Shina Caroline Lynn
Published: July 2016

The first woman to earn a Professorship at a University in Europe was Laura Maria Caterina Bassi, who earned a professorship in physics at the University of Bologna in 1732. Almost 300 years and three waves of feminism later, in 2016, women typically still only comprise 20% (or less) of the number of full professors in Europe. This opinion article will discuss the experiences of being a female academic today and the factors contributing to the academic gender gap from the perspective of a “young” natural scientist, as well as providing constructive suggestions for strategies to empower women in the academic world.
Musculoskeletal infections associated with Citrobacter koseri
Authors: Kwaees TA , Hakim Z , Weerasinghe C , Dunkow P
Published: July 2016

Introduction

Citrobacter koseri is a well known cause of central nervous system infections in the paediatric setting. Musculoskeletal infections caused by C koseri are rare, with only 14 previously reported cases. We present the first recorded case of C koseri induced septic arthritis of the knee along with a review of the literature.

Methods

A search of the PubMed, Embase® and Google Scholar™ databases was undertaken. Only complete or near complete cases were reviewed.

Findings

Fourteen musculoskeletal infections were identified. Of these, five were associated with an operative procedure and five involved a septic joint. Surgical treatment was required in the majority of cases and cure was achieved in all cases following prolonged antibiotic use.

Conclusions

C koseri associated musculoskeletal infections may complicate primary orthopaedic procedures. The organism can present aggressively and can be difficult to identify microbiologically. It is sensitive to newer generation beta-lactams, cephalosporin-based antibiotics and timely surgery.
A conflict of sexual identity: Problems of finding special occasion dresses for girls at secondary school with dress codes
Authors: Lapolla Kendra
Published: July 2016

This study examines the challenges of finding special occasion dresses for teenage females who attend secondary schools with dress codes for school-related events such as prom, homecoming and honour’s banquets. A total of 228 high school females were surveyed online to identify the most common difficulties in finding a special occasion dress to fit the dress code. In addition, three focus group sessions were carried out to follow up with interested students for further information. According to the study, formal wear retailers and school officials are sending mixed messages about the expectations of how a teenage female should present herself in public recreational settings. Results suggest teenage girls often have to navigate a compromise between a market selling too provocative clothing and a school dress code that is too strict.
Breaking the illusion: The effects of adding warning labels identifying digital enhancement on fashion magazine advertisements
Authors: Harmon Jennifer , Rudd Nancy Ann
Published: July 2016

The link between exposure to thin ideal images in the media and negative psychological impacts for women has been the focus of extensive, previous research. This link has led to recent research investigating potential avenues to mitigate these impacts by incorporating a warning label or disclaimer on fashion advertisements. In this research, the impact of incorporating a warning label in fashion advertisements on mood negativity, self-esteem and body satisfaction was investigated. Additionally measured were participants’ purchase intentions towards the product and reactions to the models and products in the advertisements. Results indicate that only body satisfaction was significantly impacted by the addition of a warning label and that participants had very different responses to models and products. Responses ranged from models influencing participants to buy products to indifference to models. Participants tended to evaluate products in terms of their fit to the participant’s personal style. Future research may want to investigate warning label wording choice and diverse samples of viewing audiences in relation to this topic.

Insulin resistance with compensatory hyperinsulinemia and atherogenic dyslipidemia was found in all patient groups.
Heart rate features among men of working age with obesity and hypertension
Authors: Tsyplenkova Nataliya S. , Panova Elena I.
Published: July 2016

Aim. To study features of heart rate of men with arterial hypertension and obesity, to identify factors associated with arrhythmia evolution.Materials and methods. The study included 3 groups of men (with obesity – 98 men, with excessive body weight – 46 men, with normal body weight – 40 men). The comparative analysis of heart rhythm was performed with Resting ECG and Holter ECG monitoring, blood pressure from daily monitoring, echocardiography, blood lipid spectrum, glycaemia. The adiponectin level was analyzed only for group with obesity.Results. Obesity in men with arterial hypertension increases the frequency of arrhythmias of atrial fibrillation (AF) type (15.3% vs. 0% in group with normal body weight, p=0.004) and increases the frequency of ventricular premature beats (VPB) (26.5% in group with obesity vs. 10% in group with normal body weight). We were also able to show the relation between arrhythmia and the severity of obesity. Obesity with arterial hypertension significantly increases the risk of various arrhythmias (more than 6 times for AF risk – p=0.004 and more than 5.31 times for frequent VPB – p=0.026. Risk factors for AF are statistically significant with the presence of obesity: left ventricular (LV) and left atrium (LA) dilation, II–III stage of hypertension and low level of high-density lipoprotein (p0.05). AF risk factors are significant without relation to obesity: left ventricular hypertrophy, dilatation LA, IHD (p0.05). But there is no relation between ischemic heart disease (IHD) and an increased risk of AF evolution. Also no relation was found between sleep apnea syndrome and arrhythmias.Conclusion. Men with excessive body weight or obesity in contrast to men with normal body weight have an increased risk of AF and VPB. Factors directly associated with arrhythmias: heart remodeling (hypertrophy and dilatation of the left ventricular, dilatation of the left atrium), advanced stages of arterial hypertension, dyslipidemia; IHD with obesity associated with risk of VPB and doesn’t affect the AF frequency.
Neighborly inscribed polytopes and delaunay triangulations
Authors: Gonska Bernd , Padrol Arnau
Published: July 2016

We construct a large family of neighborly polytopes that can be realized with all the vertices on the boundary of any smooth strictly convex body. In particular, we show that for d ≥ 4 there are superexponentially many combinatorially distinct neighborly d-polytopes on n vertices that admit realizations inscribed in the sphere. These are the first examples of inscribable neighborly polytopes that are not cyclic polytopes, and provide the current best lower bound for the number of combinatorial types of inscribable polytopes (which coincides with the current best lower bound for the number of combinatorial types of polytopes). Via stereographic projections, this translates into a superexponential lower bound for the number of combinatorial types of (neighborly) Delaunay triangulations in ℝ

Cellular homology of real maximal isotropic grassmannians
Authors: Rabelo Lonardo
Published: July 2016

In this paper we obtain a formula for the boundary map of the cellular ℤ-homology of the real maximal isotropic Grassmannians of type B, C and D which are obtained as minimal flag manifolds of split real forms of semi-simple Lie algebras of the respective type. We use the model of shifted Young diagrams presented in [9] to describe the Schubert varieties and the cellular decompositions of such flag manifolds. The results are applied to determine the orientability of the real maximal isotropic Grassmannians.

Published: July 2016

We report on a 35-year-old woman who presented at 36 weeks of gestation with headaches and arterial hypertension. She was discharged after ruling out pre-eclampsia. The next day she returned with worsening headaches and an onset of Horner’s syndrome. A magnetic resonance (MR) angiography showed extensive dissection of the right-sided internal carotid artery. Anticoagulation and antihypertensive therapies were initiated after delivery of the baby by caesarean. The patient recovered fully. Headache in pregnancy is not always due to pre-eclampsia. Carotid artery dissection (CAD) is a rare but severe cause of headache that typically presents with neck pain and focal neurologic symptoms. Once the diagnosis is established, an immediate treatment should be started in order to minimise damage, especially ischaemic lesions.
Late-onset brain abscess due to group B Streptococcus
Authors: Giannattasio Antonietta , Raimondi Francesco , D’Amico Alessandra , Lama Silvia , Spagnuolo Maria Immacolata
Published: July 2016

Background:

Group B Streptococcus (GBS) is the most common pathogen responsible for perinatal bacterial infections. While the early-onset (EO) disease typically presents with pneumonia or sepsis, bacteremia and meningitis represent usual presentation of late-onset (LO) disease. Other clinical manifestations are relatively rare.

Highlights:

Here we describe an infant with a brain abscess due to a late-onset, GBS serotype I infection. A previously healthy 42-day-old baby presented with insufficient sucking, vomiting, irritability and fever. Cerebrospinal fluid (CSF) analysis, cultures and magnetic resonance imaging (MRI) confirmed the diagnosis of type I group B streptococcal meningitis with brain abscess. The patient made full recovery after a 4-week course of treatment with meropemen and ampicillin. No surgical drainage of the abscess was required. At a 3-year follow-up, the patient had a normal global development with no neurological sequelae.

Conclusions:

Brain abscess due to GBS late-onset infection is very rarely described. Furthermore, type I GBS is infrequent in late-onset disease. Therapeutic choices in these neonates are challenging because of lack of standards. A long-term follow-up of late-onset disease survivors is mandatory to exclude late developmental impairment.
Optimization of S:Sn precursor molar concentration on the physical properties of spray deposited single phase Sn2S3thin films
Authors: Srivind J. , Nagarethinam V.S. , Balu A.R.
Published: July 2016

Nanoneedle structured Sn2S3thin films were prepared by spray pyrolysis technique from aqueous solutions of tin (II) chloride and thiourea, keeping the molar concentrations of S:Sn = 0.01:0.01, 0.02:0.02, 0.03:0.03 and 0.04:0.04 in the starting solutions. XRD studies reveal that all the films exhibit orthorhombic crystal structure with a preferential orientation along the [2 1 1] direction. The peak intensity of the (2 1 1) plane is found to be maximum for the film coated with 0.02:0.02 S:Sn molar concentration which confirms the improved crystalline nature of this film. SEM images depict that the film coated with S:Sn molar concentration 0.02:0.02 exhibit needle shaped grains. The optical band gap exhibits red shift from 2.12 eV to 2.02 eV with an increase in S:Sn precursor molar concentration. Electrical studies show that the films having S:Sn molar concentrations 0.01:0.01 and 0.02:0.02 exhibit minimum resistivity values of 0.238 and 0.359Ω ·cm, respectively.

Published: July 2016

Three-dimensional NiO nanorods were synthesized as anode material by electrospinning method. X-ray diffraction results revealed that the product sintered at 400 °C had impure metallic nickel phase which, however, became pure NiO phase as the sintering temperature rose. Nevertheless, the nanorods sintered at 400, 500 and 600 °C had similar diameters (∼200 nm).The NiO nanorod material sintered at 500 °C was chip-shaped with a diameter of 200 nm and it exhibited a porous 3D structure. The nanorod sintered at 500 °C had the optimal electrochemical performance. Its discharge specific capacity was 1127 mAh·g−1initially and remained as high as 400 mAh·g−1at a current density of 55 mA·g−1after 50 cycles.

Published: July 2016

Rapid progress in thin-film coatings based on metals, which can be deposited on polymers, has been recently observed. In this work discussion on the properties of modified polymers and silver thin films deposited on polytetrafluoroethylene (PTFE) and polycarbonate (PC) substrates has been presented. Surface of these polymer substrates were exposed to argon plasma discharge. Additionally, silver thin films were deposited on their surface by electron beam evaporation method. The surfaces of the modified polymers were studied by different methods, i.e. topography, wettability and scratch resistance measurements were performed. The ageing effect of treated substrates was also discussed. It was shown that plasma modification of PTFE and PC substrates increased wettability of their surfaces. The value of water contact angle decreased of about 40 % and 25 % for PTFE and PC surface, respectively. The change of hydrophobic to hydrophilic properties was observed. Plasma modification of substrates improved adhesion between silver coating and polymer substrates. However, it did not influence wettability of Ag coating.

A New Family of Generalized Quadratic Hazard Rate Distribution With Applications
Authors: Kayid M. , Elbatal I. , Merovci F.
Published: July 2016

The purpose of this paper is to introduce a new family of the quadratic hazard rate distribution. This new family has the advantage of being capable of modeling various shapes of aging and failure criteria. Furthermore, some well-known lifetime distributions such as generalized exponential distribution, generalized linear hazard rate distribution, and generalized Rayleigh distribution among others follow as special cases. Some statistical and reliability properties of the new family are discussed and the maximum likelihood estimation is used to estimate the unknown parameters. Explicit expressions are derived for the quantiles. In addition, the asymptotic confidence intervals for the parameters are derived from the Fisher information matrix. Finally, the obtained results are validated using a real data set and it is shown that the new family provides a better fit than some other known distributions.
High Temperature Flexural, Tensile Strength and Oxidation Behavior of Ti3SiC2 Ceramic at 900°C–1300°C in Ambient Air
Authors: He R. , Zhou Z. , Qu Z. , Cheng X.
Published: July 2016

High temperature flexural and tensile strength of hot-pressed Ti3SiC2 ceramic were measured and analyzed from 900 to 1300°C in ambient air atmosphere. The high temperature flexural and tensile strength are strong functionals of temperature. With the temperature increasing, the high temperature flexural and tensile strength decrease correspondingly. Moreover, the transition from brittle to plastic deformation was observed for both flexural and tensile testing. The oxidation behavior and oxidation mechanism were investigated.
Prolonged insulin treatment sensitizes apoptosis pathways in pancreatic β cells
Authors: Bucris E , Beck A , Boura-Halfon S , Isaac R , Vinik Y , Rosenzweig T , Sampson S R , Zick Y
Published: July 2016

Insulin resistance results from impaired insulin signaling in target tissues that leads to increased levels of insulin required to control plasma glucose levels. The cycle of hyperglycemia and hyperinsulinemia eventually leads to pancreatic cell deterioration and death by a mechanism that is yet unclear. Insulin induces ROS formation in several cell types. Furthermore, death of pancreatic cells induced by oxidative stress could be potentiated by insulin. Here, we investigated the mechanism underlying this phenomenon. Experiments were done on pancreatic cell lines (Min-6, RINm, INS-1), isolated mouse and human islets, and on cell lines derived from nonpancreatic sources. Insulin (100nM) for 24h selectively increased the production of ROS in pancreatic cells and isolated pancreatic islets, but only slightly affected the expression of antioxidant enzymes. This was accompanied by a time- and dose-dependent decrease in cellular reducing power of pancreatic cells induced by insulin and altered expression of several ER stress response elements including a significant increase inTrb3and a slight increase iniNos. The effect oniNosdid not increase NO levels. Insulin also potentiated the decrease in cellular reducing power induced by H2O2but not cytokines. Insulin decreased the expression of MCL-1, an antiapoptotic protein of the BCL family, and induced a modest yet significant increase in caspase 3/7 activity. In accord with these findings, inhibition of caspase activity eliminated the ability of insulin to increase cell death. We conclude that prolonged elevated levels of insulin may prime apoptosis and cell death-inducing mechanisms as a result of oxidative stress in pancreatic cells.

Too many swipes for today: The development of the Problematic Tinder Use Scale (PTUS)
Authors: Orosz Gábor , Tóth-Király István , Bőthe Beáta , Melher Dóra
Published: July 2016

Background and aims

Tinder is a very popular smartphone-based geolocated dating application. The goal of the present study was creating a short Problematic Tinder Use Scale (PTUS).

Methods

Griffiths’ (2005) six-component model was implemented for covering all components of problematic Tinder use. Confirmatory factor analyses were carried out on a Tinder user sample (N = 430).

Results

Both the 12- and the 6-item versions were tested. The 6-item unidimensional structure has appropriate reliability and factor structure. No salient demography-related differences were found. Users irrespectively to their relationship status have similar scores on PTUS.

Discussion

Tinder users deserve the attention of scientific examination considering their large proportion among smartphone users. It is especially true considering the emerging trend of geolocated online dating applications.

Conclusions

Before PTUS, no prior scale has been created to measure problematic Tinder use. The PTUS is a suitable and reliable measure to assess problematic Tinder use.
An investigation of breakage behaviour of single sand particles using a high-speed microscope camera
Authors: Wang W. , Coop M. R.
Published: July 2016

Much research has focused on the micro-mechanics of sand particles. The single particle uniaxial compression test is a common way to study breakage behaviour. However, there is still little agreement on particle breakage criteria and the mechanisms of breakage remain uncertain, partly because of the often rapid brittle failure of sand particles. In this study, a series of single particle uniaxial compression tests on different kinds of sand particles were carried out, using a high-speed microscope camera to capture the processes of breakage. This enabled a maximum of 2000 frames to be obtained per second to identify clearly the failure processes and crack propagation. Four failure modes have been proposed based on the rapidity of failure and the size and number of particle fragments created during the breakage: splitting, explosive, explosive–splitting and chipping. The relationship between the particle strength and the breakage mode has then been explored, investigating also whether immersion would affect the breakage mode and strength. The morphologies of the sand particles including local roundness, particle size, aspect ratio, regularity and two-dimensional sphericity were measured to investigate their influence. With assistance of the high-speed microscope camera, the crack initiation locations were identified and the frequency of different locations obtained, comparing the results with existing particle micro-mechanical theories.
Scale and flow boundary effects for air-entraining vortices
Authors: Taştan Kerem
Published: July 2016

A challenge when designing water intake structures in rivers, channels and reservoirs is to reduce the entrainment of air through free air-core vortices. Entrained air can cause discharge reduction, vibration and cavitation in the water-conveying system. This study firstly investigates flow boundary effects at the critical submergence of an intake, which is the depth up to which air entrainment occurs. The friction effect of a boundary section close to the free surface dominates the boundary blockage effect and retards the occurrence of the air-entraining vortex. Potential flow solution methods overpredict the critical submergence of an intake under the influence of boundary friction, so a design criterion is presented to correct this. Furthermore, previous work shows that Froude similarity is not always reliable for predicting critical submergence at prototype intakes. In the second part of this study, kinematic similarity – the equality of the ratios of intake velocity to the velocity at the imaginary critical spherical sink surface between the model and prototype intakes – is proposed and validated against experimental results. In addition, a theoretical explanation of the equal intake velocity concept is given using kinematic similarity.

Still ‘Watching’ TV? The Consumption of TV Fiction by Engaged Audiences
Authors: Dhoest Alexander , Simons Nele
Published: July 2016

There is no denying that television, as a medium and an institution, has drastically changed in the age of digitization and convergence. For audiences, this has not only opened up multiple opportunities to watch television content at other times and on other devices, but also to interact with its cross-media extensions. However, while much has been written about the new opportunities for audience engagement, we do not know much about the actual adoption of new technologies nor the motivations underlying such uses. Therefore, this paper draws on empirical audience research to address the key question: how do viewers engage with contemporary TV fiction? Through empirical audience research, using various qualitative research methods, three different aspects of the reception of cross-media TV fiction will be discussed: (1) how do viewers watch the TV episodes of contemporary TV fiction?, (2) how do viewers engage with the cross-media extensions of TV fiction?, and (3) how do viewers experience the social dimensions of contemporary TV fiction? We focus on a particular group, that of 'engaged' viewers, who are actively involved by personalizing their viewing practices, by communicating about it, by consuming cross-media elements of TV fiction, or producing TV fiction-related content. Our findings suggest that even this group does not make full use of all the available technological opportunities to personalize TV viewing, and that the classical TV text, linear viewing, and the social aspect of viewing remain of key importance.

Argumento, a partir da pesquisa de campo, que podemos compreender a reconfiguração das práticas do Estado em suas margens e a legibilidade das políticas de controle direcionadas às populações pobres e vulneráveis, não apenas a partir das favelas cariocas e suas representações. Tomar a Baixada Fluminense em sua constituição específica, de entrelaçamento entre mercado político e violência de um lado, e em seu aspecto relacional com o Rio de Janeiro, de outro, nos leva a compreender melhor esses diferentes regimes territoriais ocasionados pelas políticas de pacificação.
The cases Zulmira Cardoso And Brayan Capcha: Political mobilization and migrant integration in Brazil
Authors: Leão Augusto Veloso , Demant Peter Robert
Published: July 2016

Este artigo visa debater a questão dos direitos humanos dos imigrantes propondo uma reflexão sobre as mobilizações sociais de imigrantes e a importância da garantia efetiva dos direitos humanos para os imigrantes de forma a facilitar a integração desse grupo à sociedade hospedeira, não somente a partir da discussão moral sobre os direitos humanos, mas também com justificativas práticas para a integração desses grupos. Utilizamos como objeto empírico os protestos de imigrantes ocorridos em 2012 e 2013 depois da morte de imigrantes vítimas de violência urbana em São Paulo, Zulmira Cardoso e Brayan Capcha. A atual lei de imigração brasileira (Lei no 6815/1980) proíbe aos migrantes qualquer atividade de natureza política e, por esse motivo, manifestações como essas são raras e, em sua maioria, são organizadas por entidades de brasileiros que defendem os direitos dos imigrantes. O artigo propõe um estudo dos casos de mobilização de migrantes em São Paulo e procura estabelecer uma ponte entre o formato dessas mobilizações, a ausência de direitos políticos aos imigrantes e a situação da estima social de imigrantes perante a sociedade brasileira. Com base nessas informações, ensaiamos uma análise do impacto dessas mobilizações de imigrantes para o processo de integração desse grupo social e os efeitos do reconhecimento de direitos e da construção de uma estima social positiva para imigrantes neste processo de integração.
Keynes' Theory of the Interest Rate: A Critical Approach
Authors: Appelt Katarzyna
Published: July 2016

John M. Keynes – the author of General Theory of Employment, Interest and Money – assumed that the interest rate is the price which brings into equilibrium the desire to hold wealth in cash with the supply of cash resources, and the reward for parting with liquidity at the same time. He indicated liquidity preference as the key element of the theory of the demand for money, whereas the supply of money is a discretionary factor, i.e. depending on the policy pursued by monetary authorities. It has been proven that such an approach comes with at least three errors: inconsistency in defining the rate of interest, vicious circle in arguing and departure from the economics of value for functional adequacies.

“A cidade tal como ela é vista por seus habitantes”: Nova York como espaço de memória no olhar de Will Eisner
Authors: Pereira Marcos Paulo Torres , Lachat Marcelo
Published: July 2016

Este estudo objetiva compreender como o espaço urbano da cidade de Nova York, na narrativa de Will Eisner, torna-se matéria de fabulação em constructos narrativos que evocam uma entidade de urbe, matizada pela soma de representações simbólicas que lhe são ulteriores, gerando mecanismos coletivos de identificação e pertencimento, no ato de rememorar e na articulação de signos na conjugação de subjetivismos e coletividade.
A representação da realidade em “O Pintor de Retratos” e “A Margem Imóvel do Rio”, de Luiz Antonio de Assis Brasil
Authors: Steyer Fabio Augusto
Published: July 2016

O objetivo deste trabalho é analisar dois livros do escritor gaúcho Luiz Antonio de Assis Brasil cujo objetivo principal é discutir a representação da realidade em diferentes linguagens. “O Pintor de Retratos” (2001) trata do debate entre fotografia e pintura como instrumentos de captação “objetiva” da realidade, a partir de um enredo que se passa no final do século XIX. Em “A Margem Imóvel do Rio” (2004) o problema da representação da realidade volta-se para a Literatura e a História. Também ambientado no final do século XIX, narra a história do cronista oficial da corte de D. Pedro II, que viaja ao Rio Grande do Sul em busca de Francisco da Silva, a quem o imperador teria prometido um título nobiliárquico. Além das temáticas de cada livro, a idéia deste estudo é discutir também as próprias obras literárias do autor como produtoras de sentido(s) para a construção de uma determinada visão sobre a representação das realidades abordadas.

Taman Wisata Alam Kawah Ijen (TWAKI) merupakan salah satu obyek wisata di Jawa Timur yang sudah sangat terkenal akan keindahan alamnya dan semakin tahun jumlah wisatawan semakin meningkat. Namun, pengelolaan kawasan konservasi di TWAKI saat ini belum optimal dalam pengembangan ekowisatanya. Pengelolaan kawasan TWAKI menghadapi berbagai macam tantangan, dari faktor eksternal seperti vandalisme, kebakaran hutan, TWAKI menjadi mass tourism, gempa freatik dan keluarnya gas beracun, serta dari faktor internal, seperti: sumber daya, anggaran, tata batas, dan manajemen. Terkait permasalahan dan upaya pengelolaan yang telah dilakukan oleh Balai Besar Konservasi Sumber Daya Alam (BBKSDA) Jawa Timur, maka perlu dilakukan penilaian efektivitas pengelolaan kawasan konservasi di TWAKI. Tujuan penelitian ini adalah mengkaji efektivitas pengelolaan kawasan konservasi pada setiap siklus pengelolaan yaitu perencanaan, masukan, proses dan keluaran sehingga didapat rekomendasi strategis yang efektif untuk peningkatan efektivitas pengelolaan kawasan konservasi dalam pengembangan ekowisata di TWAKI. Berdasarkan hasil penilaian Management Effectiveness Tracking Tool (METT) kawasan TWAKI, didapat nilai skor METT telah mencapai nilai minimum indeks METT yang artinya kawasan konservasi sudah dikelola secara efektif. Salah satu strategi untuk mendorong pengelolaan TWAKI yang berkelanjutan, efektif dan berdampak bagi kesejahteraan masyarakat yaitu pengelolaan secara bersama dengan pemangku kepentingan (stakeholders) untuk membangun suatu model kolaborasi pengelolaan.

Published: July 2016

Kegiatan pencegahan kebakaran hutan gambut di Taman Nasional Sebangau (TNS) telah dilakukan setiap tahun oleh pengelola kawasan. Hingga kini kebakaran masih menjadi ancaman terutama di musim kemarau. Penelitian ini bertujuan untuk mengetahui penyebab kebakaran, mengukur nilai kerugian di tahun 2014 dan menganalisis efektivitas pencegahannya. Penyebab kebakaran dipicu oleh aktifitas masyarakat di dalam dan sekitar kawasan. Nilai Kerugian Total akibat kebakaran seluas ± 4364 ha mencapai Rp 134 Milyar. Kegiatan pencegahan kebakaran termasuk efektif jika hanya dilihat dari persentase penyerapan input (realisasi anggaran), namun sangat tidak efektif dilihat dari persentase pencapaian sasaran (outcome) berupa penurunan jumlah titik panas (hotspot) dan luas kebakaran. Analisis kualititatif dilakukan untuk menggambarkan kendala permasalahan di tingkat tapak. Kegiatan pencegahan harus ditingkatkan dengan lebih memperhatikan akar masalah penyebab kebakaran yaitu faktor sosial-ekonomi masyarakat.
Optimizing High‐Residue Cultivation Timing and Frequency in Reduced‐Tillage Soybean and Corn
Authors: Keene C. L. , Curran W. S.
Published: July 2016

Integrated weed management (IWM) practices are needed to prevent the development of herbicide‐resistant weeds and create more robust weed management programs. This experiment was conducted to determine the optimal timing and frequency of high‐residue cultivation in reduced‐tillage soybean [Glycine max (L.) Merr.] and corn (Zea mays L.) in Pennsylvania. Banded herbicides were applied at planting and high‐residue cultivation frequency ranged from one to three passes. A split‐plot assessed the effects of cover crop residue, either cereal rye (Secale cereale L.) in soybean or a hairy vetch (Vicia villosa Roth)‐triticale (X Triticosecale Wittm.) mixture in corn, on weed control and yields. Breakeven analyses were used to evaluate cultivation and cover crop costs. Two cultivator passes reduced weed biomass to 500 kg ha−1 or less and were needed to optimize weed control and prevent yield loss. No weed control or yield benefit was observed with three passes compared to two passes. Cover crop residues increased weed biomass and yield in dry years but suppressed weeds without influencing yields in wet years. In 1 of 3 yr, cover crop establishment costs were offset by 0.7 Mg ha−1 greater soybean yield with cereal rye residue than without. In 1 of 2 yr, a 0.8 Mg ha−1 greater corn yield with cover crop residue compared to none offset establishment costs only when legume N credit was substituted for urea fertilizer. This research confirms that banded herbicide application together with high‐residue cultivation can achieve yields similar to herbicide‐only programs while diversifying weed control tactics.

New integrated weed management approaches are greatly needed in reduced‐tillage systems to help preempt the continued evolution of herbicide‐resistant weeds.

High‐residue interrow cultivation following banded herbicide application at planting is an in‐season weed management program that combines mechanical and chemical weed control tactics. Under conditions of the experiment, two passes with a high‐residue cultivator achieved similar cash crop yield as a post‐glyphosate application in soybean and corn. Single‐pass treatments usually resulted in higher weed biomass and lower yields than two‐pass treatments, and no weed control or crop yield benefit was observed with three passes.

Rolled cereal rye and hairy vetch–triticale cover crop residues increased soybean and corn yields, respectively, in dry years despite increasing weed biomass.

Economic analyses indicated that the benefit to cash crop yield from cover crop residues will not likely exceed establishment costs in every year; however in dry years, residues can increase cash crop yield beyond breakeven levels. The higher seed cost of the hairy vetch–triticale used before corn was able to pay for itself if N provided by the hairy vetch was assumed to offset the cost of urea fertilizer.
