Depression is associated with an altered immune response, which could be normalized by antidepressant drugs. However, little is known about the influence of antidepressants on the peripheral immune response and function of macrophages in individuals not suffering from depression. Our studies were aimed at determining the influence of antidepressant drugs on the humoral and cellular immune response in mice. Mice were treated intraperitoneally with imipramine, fluoxetine, venlafaxine, or moclobemide and contact immunized with trinitrophenyl hapten followed by elicitation and measurement of contact sensitivity by ear swelling response. Peritoneal macrophages from drug-treated mice were either pulsed with sheep erythrocytes or conjugated with trinitrophenyl and transferred into naive recipients to induce humoral or contact sensitivity response, respectively. Secretion of reactive oxygen intermediates, nitric oxide, and cytokines by macrophages from drug-treated mice was assessed, respectively, in chemiluminometry, Griess-based colorimetry and enzyme-linked immunosorbent assay, and the expression of macrophage surface markers was analyzed cytometrically. Treatment of mice with fluoxetine, venlafaxine, and moclobemide results in suppression of humoral and cell-mediated immunity with a reduction of the release of macrophage proinflammatory mediators and the expression of antigen-presentation markers. In contrast, treatment with imipramine enhanced the humoral immune response and macrophage secretory activity but slightly suppressed active contact sensitivity. Our studies demonstrated that systemically delivered antidepressant drugs modulate the peripheral humoral and cell-mediated immune responses, mostly through their action on macrophages. Imipramine was rather proinflammatory, whereas other tested drugs expressed immunosuppressive potential. Current observations may be applied to new therapeutic strategies dedicated to various disorders associated with excessive inflammation.

Published: April 2016

Workplace bullying (WPB) behaviors negatively affect nurse productivity, satisfaction, and retention, and hinder safe patient care. The purpose of this article is to define WPB, differentiate between incivility and WPB, and recommend actions to prevent WPB behaviors. Informed occupational and environmental health nurses and nurse leaders must recognize, confront, and eliminate WPB in their facilities and organizations. Recognizing, confronting, and eliminating WPB behaviors in health care is a crucial first step toward sustained improvements in patient care quality and the health and safety of health care employees.
The clinical applications of genome editing in HIV
Authors: Wang Cathy X. , Cannon Paula M.
Published: April 2016

HIV/AIDS has long been at the forefront of the development of gene- and cell-based therapies. Although conventional gene therapy approaches typically involve the addition of anti-HIV genes to cells using semirandomly integrating viral vectors, newer genome editing technologies based on engineered nucleases are now allowing more precise genetic manipulations. The possible outcomes of genome editing include gene disruption, which has been most notably applied to the CCR5 coreceptor gene, or the introduction of small mutations or larger whole gene cassette insertions at a targeted locus. Disruption of CCR5 using zinc finger nucleases was the first-in-human application of genome editing and remains the most clinically advanced platform, with 7 completed or ongoing clinical trials in T cells and hematopoietic stem/progenitor cells (HSPCs). Here we review the laboratory and clinical findings of CCR5 editing in T cells and HSPCs for HIV therapy and summarize other promising genome editing approaches for future clinical development. In particular, recent advances in the delivery of genome editing reagents and the demonstration of highly efficient homology-directed editing in both T cells and HSPCs are expected to spur the development of even more sophisticated applications of this technology for HIV therapy.
Ghrelin Impairs Prandial Glucose Tolerance and Insulin Secretion in Healthy Humans Despite Increasing GLP-1
Authors: Tong Jenny , Davis Harold W. , Gastaldelli Amalia , D'Alessio David
Published: April 2016

Objectives:

Administration of ghrelin inhibits the acute insulin response to glucose and worsens IV glucose tolerance in healthy subjects. Evidence from preclinical studies suggests that ghrelin may have differential effects on glucose metabolism during fasting and feeding. Our objective was to test the effects of ghrelin on glucose and insulin responses during a meal tolerance test.

Design:

Acyl ghrelin (0.26 and 2.0 μg/kg/h) or saline was infused in 13 healthy subjects on three separate occasions in randomized order. Ghrelin was infused for 45 minutes to achieve steady-state levels and continued for 240 minutes after ingestion of a liquid test meal. Primary outcomes were area under the curve for glucose and insulin secretion.

Results:

We found that ghrelin infusions of 0.26 and 2.0 μg/kg/h raised steady-state plasma total ghrelin levels to 1.7- and 4.8-fold above fasting concentrations, but did not alter fasting plasma glucose or insulin levels. During the meal tolerance test, ghrelin decreased insulin sensitivity, impaired β-cell function, and induced glucose intolerance. The high-dose ghrelin infusion also raised postprandial glucagon like peptide 1 secretion without affecting glucose dependent insulinotropic polypeptide, glucagon, or peptide YY concentrations.

Conclusions:

We conclude that both physiologic and pharmacologic doses of ghrelin worsen the glucose and β-cell responses to meal ingestion in healthy humans. The increase in postprandial glucagon like peptide 1 secretion by ghrelin suggests a novel enteroendocrine connection, but does not mitigate the glucose intolerance.
The Mediterranean's Future in an Age of Uncertainty
Authors: Engelke Peter
Published: April 2016

As tempting as it is to forecast the Mediterranean's future through the bleak lens of its present, it is unwise to do so. Over and again throughout history, writing the future through the linear extrapolation of contemporary trends has proven foolish. This essay identifies the most critical socioeconomic, political, ecological, and geopolitical drivers of change that together will shape the Mediterranean's future. It analyzes the possible impacts of three major trends (demographic imbalance, ongoing empowerment, and rising natural resource stresses) and three critical uncertainties (the future of collective identity, the role of distant global powers, and economic turbulence).

The method of receiving vectors allows us to determine cosmic ray anisotropy at each moment. Also, the method makes it possible to study fast anisotropy fluctuations related to the interplanetary medium dynamics. Receiving vectors have been calculated earlier for neutron monitors and muon telescopes. However, the most of muon telescopes of the network of cosmic ray stations for which calculations were made does not operate now. In recent years, new improved detectors appeared. Unfortunately, the use of them is limited because of absence of receiving coefficients. These detectors include the matrix telescope in Novosibirsk. Therefore, components of receiving vector for muon telescopes of observation cosmic ray station “Novosibirsk” have been defined. Besides, design features of the facility, its orientation, and directional diagram depending on zenith and azimuth angles were taken into account. Also, for the system of telescopes, we allowed for coupling coefficients found experimentally using the test detector.

THE VALUE OF RUSSIAN INSTITUTION OF ELDERS IN MATTERS OF CORRECTION OF JUVENILE OFFENDERS IN RUSSIA IN XIX - EARLY XX CENTURY
Authors: Матвеева  , Matveeva Evgeniya
Published: April 2016

The article analyzes the changes in the spiritual, moral and religious climate in Russian society in XIX - early XX century. The peculiarities of national modernization, that predetermined the gradual destruction of the traditional patriarchal way of life of the masses, are revealed; they led to the transformation of the world towards its secularization. The underlying problems of "religious ignorance" of a large part of the Orthodox population of the central part of Russia are determined, which are expressed in a large number of superstitions, prejudices and heresies incompatible with the official teaching. The crisis of the Russian Orthodox Church (ROC) is characterized, which is expressed in the rapid numerical growth of the various sects, strengthening of the Old Believer communities, the development of free God-seeking and spreading atheism. The pedagogical foundations of Russian Institute of elders are considered in the article, which determine certain anthropological strategy for Russia and are based not only on legal laws, but also on spiritual and moral primordial. Great importance is paid to the justification of the role of the institutions of elders in matters of correction of juvenile offenders.
Optimal fiscal policy in an open economy with capital income shifting and consumer cross-border purchases
Authors: Kudła Janusz , Kocia Agata , Kopczewska Katarzyna , Kruszewski Robert , Walczyk Konrad
Published: April 2016

The paper presents a fiscal policy model integrating tax avoidance, the complexity of tax systems and the fiscal solvency hypothesis within the traditional framework of tax competition. Furthermore, we take into account: taxation of consumption, possibility of capital income shifting and foreign goods purchases (untaxed in the destination country). We conclude that if fiscal policy is by no means unfettered the equilibrium can be allocation efficient, provided that the marginal rate of substitution between private and public goods is one. The changes in public debt affect tax rates in equilibrium differently: positively for the consumption tax rate and negatively for the labor tax rate. The change of the capital tax depends on the level of economic internalization. This approach is especially useful during a solvency crisis and can be applied to predict tax rates’ adjustment when the bonds issuance decreases or public debt accelerates.
Comparative analysis of innovative activity determinants in selected SMS’s in Brazil and Poland. Results of empirical researches
Authors: Norek Tomasz , Arenhardt Daniel Luis
Published: April 2016

Currently, technological parks constitute the most organisational and conceptually developed type of innovation centres and entrepreneurship. This results in the fact that they can be encountered in all highly developed countries in the world. They are also formed in the catching-up countries. However, one should consider whether the stimulation of innovation in the countries, which are not based on knowledge through institutional solutions used in the developed countries will turn out to be effective. Because between these countries there is a technological gap. The aim of the article was therefore to determine, using the probit modelling, the direction and strength of technological parks on the innovation activity. The study covered two provinces: Silesian, which is one of the most developed regions in Poland and Pomeranian with the intermediate industrial system. The influence of technological parks on innovation was determined based on the survey conducted in 1453 industrial enterprises. The main conclusions are brought down to the following theses: (1) using the technological parks increases the chance for the implementation of new solutions by enterprises, (2) parks to a greater extent stimulate the innovation activity in the developed province, (3) enterprises entering in the cross-regional network relations favours the selection of the technological park as the catalyst for innovation processes.

The North Atlantic Ocean contains diverse patterns of seasonal phytoplankton blooms with distinct internal dynamics. We analyzed blooms using remotely-sensed chlorophyll a concentration data and change point statistics. The first bloom of the year began during spring at low latitudes and later in summer at higher latitudes. In regions where spring blooms occurred at high frequency (i.e., proportion of years that a bloom was detected), there was a negative correlation between bloom timing and duration, indicating that early blooms last longer. In much of the Northeast Atlantic, bloom development extended over multiple seasons resulting in peak chlorophyll concentrations in summer. Spring bloom start day was found to be positively correlated with a spring phenology index and showed both positive and negative correlations to sea surface temperature and the North Atlantic Oscillation in different regions. Based on the characteristics of spring and summer blooms, the North Atlantic can be classified into two regions: a seasonal bloom region, with a well-defined bloom limited to a single season; and a multi-seasonal bloom region, with blooms extending over multiple seasons. These regions differed in the correlation between bloom start and duration with only the seasonal bloom region showing a significant, negative correlation. We tested the hypothesis that the near-surface springtime distribution of copepods that undergo diapause (Calanus finmarchicus, C. helgolandicus, C. glacialis, and C. hyperboreus) may contribute to the contrast in bloom development between the two regions. Peak near-surface spring abundance of the late stages of these Calanoid copepods was generally associated with areas having a well-defined seasonal bloom, implying a link between bloom shape and their abundance. We suggest that either grazing is a factor in shaping the seasonal bloom or bloom shape determines whether a habitat is conducive to diapause, while recognizing that both factors can re-enforce each other.
CPD article: Management of open fractures: part 2
Authors: Perry Karen L
Published: April 2016

Open fractures have been considered one of the true orthopaedic emergencies by some, however, optimal treatment has not been definitively described. Significant debate has focused on the most appropriate method by which to manage open fractures, but general principles of treatment are well established. Principles include fracture classification, antibiosis, irrigation, debridement, wound management and fracture stabilisation. In this second in a two-part series on open fracture management, debridement, wound management and fracture stabilisation will be explored; the initial management of the patient was discussed in the first article in the series. Debridement should be performed on an urgent but not emergent basis; adequacy of debridement and timeliness of soft tissue coverage are probably more important than time from injury to debridement. Once the wound has been appropriately irrigated and thoroughly debrided, early aggressive treatment, with rigid bone fixation and soft tissue reconstruction, is widely accepted as the treatment of choice. Generally, type 1 and 2 open fractures can be stabilised using the same method of fixation as would be used for a closed fracture of similar configuration, while the extensive soft tissue damage associated with type 3 fractures may preclude internal fixation.
Cardiomegaly and pericardial effusion in a beauty rat snake
Authors: Cope Iain , Fiddes Matt , Pellet Sarah
Published: April 2016

Few treatment options are reported in snakes for the treatment of cardiac conditions and reptile cardiology continues to need further investigation. This case report discusses the first report of pericardial effusion in an Asian beauty rat snake (Orthriophis taeniurus), and the creation of a pericardial window to help treat the condition. The snake presented with bilateral exophthalmos, changed behaviour, and regurgitation of food items. Physical examination revealed a ventral swelling in the region of the heart and this was confirmed by radiography and ultrasonography. The pericardium was distended with a significant pericardial effusion, while the heart remained a relatively normal size. Unfortunately finances were limited, therefore treatment was instigated without further diagnostics. Initially this involved oral frusemide and metronidazole, along with pericardiocentesis. Acupuncture was also used to help treat the snake's behavioural changes, as the owner was keen on alternative medicine. Due to the recurrent nature of the disease, the owner agreed to surgery to create a permanent pericardial window, aiming to permanently relieve the pericardial effusion. The surgery itself was simple to perform and was initially successful in preventing further build-up of pericardial fluid. However, the snake died 5 days post surgery of unknown cause. In this report we discuss this surgery and potential treatment options.

Published: April 2016

Background/Aims:

The Touch Accessible Platform for Interactive Technology (TAPit) is an interactive learning station, with a large touch screen providing access to the Internet and other resources. The aim of this study was to investigate the physical, psychosocial and functional impact of the TAPit on an individual living with spinal cord injury.

Methods:

This study employed a mixed methods case study design. Quantitative data was analysed descriptively, and both quantitative and qualitative data was classified according to the dimensions.

Results:

The introduction of the TAPit to the participant addressed aspects of doing, being, becoming and belonging, and had an immediate and successful impact for her, as she achieved two long-held and meaningful goals during a short trial. Strengths and limitations for the TAPit were identified in regards to people with spinal cord injury, along with directions for future development.

Conclusions:

This case study provides the first evidence about the effectiveness of the TAPit as an item of assistive technology for people with spinal cord injury, including participant perspectives on its use. This study demonstrates its potential as a device to support people to be able to participate in meaningful activities and occupations and that the provision of suitable adaptations and apps are the key to its success.

We study the lower semicontinuity of some free discontinuity functionals with linear growth defined on the space of functions with bounded deformation. The volume term is convex and depends only on the Euclidean norm of the symmetrized gradient. We introduce a suitable class of surface terms, which make the functional lower semicontinuous with respect to ${L^{1}}$ convergence.

Improving the Dynamic Response during Field Weakening Control of IPMSM Drive System using Adaptive Hysteresis Current Control Technique
Authors: Naik Amiya , Panda Anup Kumar , Kar Sanjeeb Kumar
Published: April 2016

This paper presents the control of IPMSM drive in flux weakening region, for high speed applications. An adaptive hysteresis band current controller has been designed and implemented in this work to overcome the drawbacks which are present in case of conventional hysteresis band current controllers such as: high torque ripple, more current error, large variation in switching frequency etc. The proposed current controller is a hysteresis controller in which the hysteresis band is programmed as a function of variation of motor speed and load current. Any variation in those parameters causes an appropriate change in the band which in turns reduces the torque ripple as well as current error of the machine. The proposed scheme is modeled and tested in the MATLAB-Simulink environment for the effectiveness of the study. Further, the result is validated experimentally by using TMS320F2812 digital signal processor.

A Four Frames Analysis to Address the Information Challenges of Families of Children with ADHD: Actions for Public Libraries to Address Embedded Power Imbalances
Authors: Douglass Kimberly , Mehra Bharat
Published: April 2016

This theoretical paper uses Bolman and Deal’s (2013) Four Frames Analysis to define the information world of families of children who present symptoms associated with attention deficit hyperactivity disorder (ADHD). ADHD is explored here as an information challenge imposed by fragmented views of an ADHD information world. This call to action explores and organizes the transdisciplinary literature about ADHD experiences into a guide that informs the social justice efforts of public libraries/librarians, who can serve as intermediaries between information stakeholders and the vast array of information resources about ADHD. These intermediaries can develop collections and services to support shared decision making among various ADHD stakeholders. To support these efforts, we identify information resources needed by users. More importantly, however, we help libraries/librarians recognize the frames they use to interpret users’ information needs for collection development.
Information Literacy Education in the South African Classroom: Reflections from Teachers’ Journals in the Western Cape Province
Authors: Zinn Sandy , Stilwell Christine , Hoskins Ruth
Published: April 2016

This qualitative study reports on teachers in the Western Cape as they attempt to embed information literacy in their classrooms. It explores how teachers come to understand information literacy and the extent to which they change their beliefs about guiding research projects in a more concerted way. The research questions were: (1) how do teachers understand information literacy education? (2) how do teachers make their information literacy explicit in the classroom? and (3) at what level are teachers’ web knowledge and skills? The teachers, who were part of an information literacy education course, formed a purposive sample. The data for this study emanated from solicited, reflective journals which participants kept over a period of eight to 10 weeks. Information seeking and use theory and an inquiry-based approach to learning frame this research. Motivation for the study is rooted in a curriculum which embodies information literacy characteristics. Traditionally, information literacy has been the domain of the school librarian. Only 16.82 % of South African schools have a stocked library. With so few school libraries and no official position in schools for a qualified school librarian, the onus for teaching information literacy thus rests on the teacher. This article provides the context for South African education and a review of the information literacy literature with an emphasis on South Africa and teachers’ information literacy. The results show that, despite many obstacles in these teachers’ paths, they express a fairly sound understanding of information literacy education by the end of the journaling exercise. However, fewer teachers can competently mediate information literacy in the classroom. One of the major barriers to information literacy is the teachers’ slow adoption of the World Wide Web. Recommendations for further study include examining teacher education programmes for their inclusion of information literacy education; for awareness of plagiarism and the ethics of information use in the school environment; and the effect of information and communication technology on learners’ information literacy.

Decomposition studies of group 6 hexacarbonyl complexes. Part 2: Modelling of the decomposition process
Authors: Usoltsev Ilya , Eichler Robert , Türler Andreas
Published: April 2016

The decomposition behavior of group 6 metal hexacarbonyl complexes (M(CO)6) in a tubular flow reactor is simulated. A microscopic Monte-Carlo based model is presented for assessing the first bond dissociation enthalpy of M(CO)6complexes. The suggested approach superimposes a microscopic model of gas adsorption chromatography with a first-order heterogeneous decomposition model. The experimental data on the decomposition of Mo(CO)6and W(CO)6are successfully simulated by introducing available thermodynamic data. Thermodynamic data predicted by relativistic density functional theory is used in our model to deduce the most probable experimental behavior of the corresponding Sg carbonyl complex. Thus, the design of a chemical experiment with Sg(CO)6is suggested, which is sensitive to benchmark our theoretical understanding of the bond stability in carbonyl compounds of the heaviest elements.
Aging analysis of high voltage silicone rubber/silica nanocomposites under accelerated weathering conditions
Authors: Khattak Abraiz , Iqbal Muhammad , Amin Muhammad
Published: April 2016

Silicone rubber (SiR) is extensively used in outdoor insulation and other applications. However, like other polymers, SiR also degrades and lessens its performance in the exposition of environmental stresses. Nanofillers improve the aging behavior of polymeric insulating materials. To investigate the effect of nanosilica on the aging behavior of SiR, we fabricated nanocomposites of SiR with 2.5 wt.% nanosilica (SNC-2.5) and 5 wt.% nanosilica (SNC-5) by mechanical mixing and ultrasonication method. The prepared samples were subjected to uniform ultraviolet (UV) radiation, heat, humidity, salt fog, and acid rain along with neat SiR in cyclic manner at 2.5 kV for 5000 h in a specially fabricated weathering chamber. Neat SiR and both nanocomposites showed gradual decrease in transparency. Random loss and recovery in hydrophobicity and increase and decrease in leakage current (LC) were recorded for all samples, in which SNC-5 showed the best hydrophobic behavior and least LC. For SNC-5, Fourier transform infrared (FTIR) results showed negligible reduction in absorption peaks at important wave-numbers and increase and intactness were observed at absorption peaks related to the hydrophobic methyl group. Scanning electron microscopy (SEM) results also concurred with FTIR, LC measurements, and hydrophobicity analysis.
New Data on the Genus Sucinoptius (Coleoptera, Ptinidae) from Rovno Amber
Authors: Bellés X. , Perkovsky E. E.
Published: April 2016

Study of five examples of spider beetle inclusions from Rovno amber revealed that at least three of these spider beetles belong to the genus Sucinoptinus Bellés et Vitali, 2007, of them, S. rovnoensis sp. n. (most probably from Klesov) and S. brevipennis sp. n. from Dubrovitsa are described. S. rovnoensis is similar to the previously known S. bukejsi Alekseev in having the same general structure of pronotum and elytra, differing from it by the morphology of pronotal sides, which are only slightly rounded and practically not constricted near the base, whereas in S. bukejsi the sides are well rounded leaving a slight but clear constriction near the base. S. brevipennis is similar to S. bukejsi Alekseev and S. sucini Bellés et Vitali in having the same general structure of the prothorax, but differing from them in having much shorter elytra. Addition of these two new species to the two previously known, S. sucini, from the eastern Baltic Sea coast, and S. bukejsi, from Kaliningrad Region, indicates that the genus Sucinoptinus was much more diverse and widespread in Late Eocene forests than former reports suggested.
The Role of Anthropogenic Influence on Biological Signal Field (BSF) Characteristics of the Wolf, Canis lupus lupus (Canidae, Carnivora)
Authors: Shkvyria M. G. , Yakovlev Ye. B.
Published: April 2016

The main goal of the current research includes studying the biological signal field (BSF) characteristics of the wolf (Canis lupus lupus Linnaeus, 1758) at different values of anthropogenic load on territories with conservation (Białowieża National park (Poland)) and hunting status of the species (Chornobyl Exclusion Zone (Ukraine)). The research in Białowieża Primeval Forest was conducted in two stages: study of the BSF characteristics of the wolf and finding correlation between data acquired from Ukraine (the first stage), and over-time study of intensity of the biological signal field (the second stage). In result of the first stage, there was no significant dependence on the characteristics of the territory and the differences between the behavior of wolves in the Białowieża Primeval Forest (conservation status of the species) and the Exclusion Zone (game status). During the second stage it was determined that provided variance of the intensity between territory groups was insufficient, the degree of significance to animals of area categories varied with the stages of the pack’s life. It was found that the main factors which govern the character of wolf activity are not the level of the anthropic load and hunting pressure, but periods of the life cycle and spatial structure of groups.
First Record of Postcranial Bones in Devinophoca emryi (Carnivora, Phocidae, Devinophocinae)
Authors: Rahmat S. J. , Koretsky I.
Published: April 2016

The Devinophoca emryi material from the early Badenian, early Middle Miocene (16.26–14.89 Ma) presents mixed cranial and especially postcranial characters with the three extant phocid subfamilies (Cystophorinae, Monachinae and Phocinae), as well as unique postcranial characters not seen in any taxa. These distinguishing characters (i. e. well-outlined, large oval facet on greater tubercle of humerus; broader width between the head and lesser tubercle of humerus; femoral proximal epiphysis larger than distal; thin innominate ilium that is excavated on ventral surface) demonstrate that this material belongs to a recently described species (D. emryi). During ecomorphotype analyses, fossil humerus and femur bones were directly associated with their corresponding mandible to reveal associations based on Recent morphological analogues. Strong correlation between ecomorphotypes and postcranial morphology supports placement of this material to D. emryi and not its sister taxon, D. claytoni. The previously described skull, mandible and teeth and postcranial bones described herein were discovered at the same locality during excavations at the base of the Malé Karpaty Mountains (Slovakia), at the junction of the Morava and Danube rivers. The geological age of D. emryi and the presence of mixed characters strongly suggest that this species was an early relative to the ancestor of seals, possibly being a terminal branch of the phocid tree. This material allows for emended diagnoses of the species, updated assessments of geographical distribution and provides further material for clarification of controversial phylogenetic relationships in Phocidae.

Published: April 2016

Genossenschaften werden oft aus ihrem durch genossenschaftliche Prinzipien definierten Idealbild diskutiert. Fraglich ist, ob und wieweit dieses Bild mit den tatsächlichen Perzeptionen übereinstimmen. In der vorliegenden Studie wird die Wahrnehmung der genossenschaftlichen Werte in der österreichischen und schweizerischen Bevölkerung untersucht, um einerseits Parallelen wie auch Differenzen zu ermitteln. Obwohl die Befunde kein einheitliches Bild zeigen, lässt sich ein gemeinsamer Wahrnehmungskern erkennen.
Surface Roughness in Nanofluid Minimum Quantity Lubrication Milling of AISI 430 Ferritic Stainless Steel
Authors: Uysal Alper
Published: April 2016

Stainless steels have been used in different fields such as automotive, aerospace, construction, medical instruments, etc. and machining operations have been applied in many of these sectors. However, machinability of stainless steel is difficult due to their hardening tendency and low thermal conductivity. In addition, researchers have struggled with improving the surface quality of machined stainless steel parts. For this reason, a surface roughness investigation was carried out in MQL (minimum quantity lubrication) milling of AISI 430 ferritic stainless steel. The experiments were conducted using uncoated and TiN (titanium nitride) coated WC (tungsten carbide) cutting tools under dry, pure MQL and nanofluid MQL conditions. A commercial vegetable cutting fluid was used as a base fluid and two nanofluids were prepared by adding 0.5 and 1 weight percent nanographene particles to the vegetable cutting fluid. In MQL milling operations, MQL flow rates were adjusted at 20 and 40 mL/h and spindle speed, feed rate, and depth of cut were selected as 995 rpm, 180 mm/min, and 0.5 mm, respectively. Depending on the experimental results, lower surface roughness values were obtained in nanofluid MQL milling due to the cooling and lubrication effects of nanographene particles.

María de Nazaret es, por excelencia, el arquetipo de creyente para todos los seguidores de Jesucristo. Ella es quien, gracias a su fiat, supo hacerse “toda oídos” para escuchar a Dios que la visitaba y la escogía para ser portadora del Mesías; al constituirse, al mismo tiempo, en portadora de la Buena Nueva para todas las generaciones. Es la mujer visitada por Dios y, desde esa experiencia, la que visita a otros y lleva a Dios mismo dentro de sí.

Palabras Clave: María, fiat, llamar, anunciación.
Skaitytojo įveika Vytauto Kavolio tekstų analizėje
Authors: Noreika Alvydas
Published: April 2016

Straipsnyje aptariamas Amerikos lietuvių sociologo Vytauto Kavolio požiūris į jo plačiai tai­kytos ir propaguotos tekstų analizės pobūdį. Įrodinėjama, kad plačiai priimta subjektyvistinė Kavolio tyrimų interpretacija neatitinka paties mokslininko pozicijos. Visai kitokias – objektyvistines – Kavolio nuostatas pirmiausia liudija jo plėtojama teksto ir prasmės ontologija. Pastarojoje tekstas ir jo branduolį sudarančios prasmės laikomos savaimine, nuo interpretatorių nepriklausoma tikrove. Taip pat straips­nyje teigiama, kad objektyvistinei Kavolio pozicijai tekstų analizės srityje neprieštarauja nei, kaip būtų galima manyti, mokslininko metodologinis pliuralizmas, nei pritarimas idėjai apie vertybinį tyrimo pro­blemų pasirinkimo sąlygotumą. Aptariamas ir Kavolio santykis su hermeneutiniu metodu. Tvirtinama, jog analizuodamas tekstus sociologas nesinaudoja šiuo populiariu metodu. Vietoj jo jis renkasi kitus: froidistinį, egzistencialistinį, struktūralistinį, poststruktūralistinį ir struktūrinį-funkcinį aiškinimo būdą.

Published: April 2016

Minimaliojo darbo užmokesčio (MDU) reguliavimas yra svarbus valstybės ekonominės ir socialinės politikos gyvendinimo instrumentas. Jo taikymo veiksmingumą lemia teisinių nuostatų atitikimas socialinei-ekonominei sanklodai. Šio tyrimo tikslas – taikant dauginę atitikties analizę, nustatyti MDU ir makroekonominių rodiklių kaitos dėsningumus Europos Sąjungos (ES) valstybėse narėse. Tyrimo uždaviniai: 1) apibūdinti teorinius MDU reguliavimo aspektus ir jų įgyvendinimą ES valstybėse narėse; 2) parengti dauginės atitikties analizės modelį sąsajų tarp MDU ir makroekonominių rodiklių atskleidimui; 3) nustatyti ryšius tarp MDU ir makroekonominių rodiklių ES valstybėse narėse. Tyrimas apima 2007–2013 m. laikotarpį, taigi nagrinėjami tiek recesijos, tiek ekonominio augimo periodai. Taikant dauginę atitikties analizę nustatyta, kad minimaliojo darbo užmokesčio lygis Europos Sąjungos valstybėse yra tiesiogiai susijęs su jų makroekonominiais rodikliais. Stabilūs ryšiai tarp rodiklių rodo, kad minimaliojo darbo užmokesčio reguliavimas turi būti atliekamas kompleksiškai vertinant bendrąją ekonomikos situaciją. Priešingu atveju, gali būti susiduriama su padidėjusiu nedarbo lygiu.
The impact of the manager's emotional intelligence on organisational performance
Authors: Karolis Karolis
Published: April 2016

The problem dealt with in the paper is the impact of manager's emotional intelligence (EI) on the economic, social, and ecological sides of the organisational activity and the qualitative criteria of the evaluation of the organisational performance from the viewpoint of sustainable development (SD) of the organisation. The aim of the paper is to justify the interrelationship of the EI of the manager of an organization and the performance of the organization in terms of its sustainable development. Methodology: to evaluate EI, the methodology proposed by J. N. Hall (2005) was adopted as a basis, by means of which the EI of the respondents – the heads of eight organisations that provided a wide range of services (logistics, ICT, etc.) – has been measured. To evaluate the effectiveness of the organisational performance, the indicators of effectiveness proposed by R. S. Kaplan and D. P. Norton (1992, 2001) and supplemented by the author – a balanced scorecard (BS) – has been applied. It was established that, in the evaluation of any organisation, the existing BS of economic indicators should be supplemented by social-cultural and environmental instruments. The EI of managers was found to be closely related both to the individual indicators of the organisational performance and with the integrated BS.

Resumo O estudo objetivou descrever a dependência relacionada às atividades de compra, preparo e ingestão de alimentos em idosos residentes na cidade de Pelotas, Rio Grande do Sul. Análise bivariada e regressão logística ordinal avaliaram a relação entre as três dependências e as exposições estudadas. Dentre os 1.451 idosos estudados, 21,1% precisavam de ajuda para alguma atividade e o cuidado foi principalmente realizado por filhos e cônjuges. A maior prevalência foi encontrada na atividade de comprar alimentos (20,7%), seguida por preparar a refeição (11,5%) e alimentar-se (2,0%). Idosos com 80 anos ou mais apresentaram mais chance de estar em uma categoria de maior dependência em relação aos de 60 a 69 anos, atingindo um odds de 5,0 para homens e 7,1 para mulheres. Para os que consideravam sua saúde regular, ruim ou muito ruim, a chance foi em torno de 2,3 vezes maior, sendo similar entre os sexos. As mulheres sem companheiro apresentaram 1,7 vezes mais chance e as com maior escolaridade apresentaram 70,0% de proteção em relação às suas categorias de referência; homens mais pobres apresentaram 5,3 vezes mais chance em comparação aos mais ricos. Os resultados apontam os subgrupos mais vulneráveis para apresentarem dependências e a importância do familiar cuidador.
