AN UNUSUAL TOURMALINE COMPOSITION FROM SITHONIA PENINSULA (NORTHERN GREECE)
Authors: Aurisicchio C. , Bartolomei A. , Kyriakopoulos K. , Magganas A.
Published: June 2018

The variety and wideness of substitutions shown by tourmaline group, mainly in the Ζ, Y and X sites, make possible a high number of real and hypothetical endmembers. However in some cases it is not so obvious to determine to what endmembers to refer to, but the wide stability field of tourmaline and its occurrence in different geological environments make useful to define the composition as percentages of end-members to trace back to its genesis. In this paper the followed procedure to identify the components of a complex tourmaline is given. During a study on the granitoid intrusions outcropping on Sithonia, Chalkidiki Peninsula (Northern Greece), a swarm of very small crystals of tourmaline, subhedral or more often allotriomorphic, has been found as stuffing of subparallel micro fractures in the quartz core of a pegmatite dike. Their composition, analysed by EMPA, turns out to be rather unusual and not satisfactorily referable to so far proposed solid solutions. It is characterized by remarkable Al deficiency (ZAl < 6 apfu), high amounts of magnesium and iron with Mg > Fe and Να dominating X site. On the basis of compositional and crystal-chemical evidences, supported by previous literature, it was hypothesized that Mg and Fe have to be referred to an uvite — feruvite component, while the considerable part of total iron in its trivalent oxidation state yields a povondraitic component according also with Na in X site. These data, coupled with a theoretical evaluation of bond valence sum (B VS) that allowed inferring the presence of OFT anions in the W site, make reasonable to consider Sithonia tourmaline as the new variety sodian povondraitic hydroxil uviteferuvite. On the basis of its composition, of its fabric and of the oscillatory trends shown by the main elements of Y and X sites, this tourmaline may be considered post magmatic likely of hydrothermal genesis.

Published: June 2018

An extensive geochemical survey on the fluids released by the volcanic/geothermal system of Methana was undertaken. Characterization of the gases was made on the basis of the chemical and isotopie (He and C) analysis of 14 samples. CO2 soil gas concentration and fluxes were measured on the whole peninsula at more than 100 sampling sites. 31 samples of thermal and cold groundwaters were also sampled and analysed to characterize the geochemistry of aquifers. Anomalies referable to the geothermal system, besides at known thermal manifestations, were also recognized at some anomalous degassing soil site and in some cold groundwater. These anomalies were always spatially correlated to the main active tectonic system of the area. The total CO2 output of the volcanic system has been preliminary estimated in about 0.2 kg s~ . Although this value is low compared to other volcanic systems, anomalous C02 degassing at Methana may pose gas hazard problems. Such volcanic risk, although restricted to limited areas, cannot be neglected and further studies have to be undertaken for its better assessment.
IDENTIFICATION OF TREATED-COLOR FRESHWATER CULTURED PEARLS

Published: June 2018

Demand for colored pearls has grown during the last thirty years. Colored pearls are rarer than white ones. Thus treated-color pearls have entered the marketplace and their identification became a challenge for the gemologists. With only the help of visual observation, EDXRF and X-radiography, methods that are used today for pearls identification, it is not always easy to identify them. Previous studies, have established that Raman scattering is useful to detect pigments in cultured freshwater pearls. The present study is based on the measurement of the Raman spectroscopy of 35 natural colored freshwater pearls and 15 treated-color freshwater pearls, covering a wide range of typical colors for this material, with green excitation. All natural- color pearls show the two major Raman resonance features of polacetyenic pigments assigned to C=C stretching-at about 1530(±25) cm'1- and C-C stretching - at about 1130(±10) cm' -, regardless of their specific hue. In this paper it is proposed that the absence of these Raman features prove the artificial origin of pigments in a colored freshwater cultured pearl.
PRELIMINARY RESULTS UPON CRYSTALLIZATION OF THE CALCITE-SPHEROCOBALTITE SOLID SOLUTION
Authors: Katsikopoulos D. , Gonzälez-Fernändez A. , Prieto M.
Published: June 2018

The (Ca,Co)C03-H20 system was studied at 25 °C using both precipitation experiments and crystallization in silica gel in order to examine the thermodynamic properties and crystallization of the solid solution. Near the CaC03 endmember, unit cell parameters and volume of the solid phase show an almost linear variation, while near the C0CO3 endmember, the growth of a phase of low crystallinity prevented those calculations. A detailed Fourier Transform Infrared Spectroscopy (FTIR) assigned this phase to a cobalt carbonate hydrate (CoCO}nH20). The fact that cell volumes are plotted above the line that corresponds to the theoretical cell volumes of the two endmembers, indicates positive value of excess volume of mixing (VE), and consequently a non-ideal solid solution. Nucleation under conditions of high supersaturation in gels showed that in all the cases the degree of cobalt incorporation in crystals was low with an average value of cobalt mole fraction (XC0CO3) around 0.03 while -even in the Co-rich zones- this value never exceeded the upper limit of 0.2. Crystal morphologies also exhibited a wide variety of forms as a function of aqueous phase composition.
GEOCHEMICAL CHARACTERIZATION OF SATELLITE HYDROCARBON FORMATIONS IN PRINOS-KAVALA BASIN (NORTH GREECE)
Authors: Kiomourtzi P. , Pasadakis N. , Zelilidis A.
Published: June 2018

Conditions favoring generation, migration and trapping of hydrocarbons generated economically significant reservoirs in Prinos-Kavala Basin. Prinos oil field and South Kavala gas field are characteristic examples. The submarine fan packed the basin during Upper Miocene. The hydrocarbons were accumulated in turbidites, deposited in a strongly reducing environment, with high sulfur concentration. Evaporates are also deposited before and after the turbidite system. In this study, which is part of a doctorate thesis, extracts retrieved from cored samples of two satellite formations in Prinos-Kavala Basin, Epsilon and Kalirahi, selected at the "Prinos equivalent" formations, have been analyzed, using geochemical methods, and found to exhibit common compositional characteristics. The analysis of biomarkers indicates that the bitumens are immature and non-biodegraded, while their origin is considered mainly algal, with minor terrestrial contribution. Variations on characteristic geochemical ratios between formations, such as Pr/Ph, Ts/Tm, oleanane/hopane and steranes index, are attributed to differences on the type of organic mater input, or the depositional setting of sediments. The identification of the organic matter type, the hydrocarbons generation, migration paths and traps of each structure within the basin is vital for the evaluation of a reliable model of the basin and further hydrocarbon exploration in North Aegean basins
PLAGIOGRANITIC ROCKS OF EVROS OPHIOLITE, NE GREECE
Authors: Magganas A.
Published: June 2018

Dykes or small stocks of plagiogranitic rocL· occur below the extrusive sequence and in mutually interpenetrating association with the sheeted dyke complex of the Evros Ophiolite, NE Greece. They are classified as tonalités, low silica trondhjemites (LST) and high silica trondhjemites (HST). Pétrographie and geochemical data suggest they resemble oceanic plagiogranites ofSSZ origin. Their normalized rock/ORG diagrams reveal ORG compatible element values, slightly depleted relative to ORG incompatible elements and Ba, Ta and Nb negative anomalies. Plagiogranites also show subparallel, relatively flat REE patterns with variable Eu anomaly. As such geochemical features are also found in the dacitic to rhyodacitic lavas of Evros Ophiolite, it is assumed that plagiogranitic melts, especially of LST composition, presumably fed them. As a first approximation to plagiogranites origin, it is suggested tonalité and HST could have been generated by 5-15 % partial melting of oceanic gabbros, whereas LST may possibly derive by fractional crystallization of a MORB type source. In a later stage, intense hydrothermal metamorphism affected the plagiogranites causing formation of peculiar epidositic spherical clots and veinlets

GEOCHEMICAL- MINERALOGICAL AND METALLOGENETICAL ASPECTS CONCERNING THE ORIGIN OF SEDIMENTS FROM LEG. 22 D.S.D.P DRILLED SITES 212 AND 213 IN EASTERN INDIAN OCEAN
Authors: Papavassiliou C. T.
Published: June 2018

Basic mineralogical and geochemical data, are presented for sediment core samples from Deep Sea Drilling Project(D.S.D.P) boreholes .Sites 212 and 213 respectively, from the eastern Indian Ocean. In both Sites the Fe-Mn oxides are abundant controlling a numerous suite of trace elements. In Site 212 the Fe-Mn oxides are more abundant in the upper part of the borehole having mainly a diagenetic or hydrogenous origin, whilst in Site 213 these oxides are more abundant in the lower part having mainly a hydrothermal origin. In both Sites clay minerals are consisting mostly of the expandable mixed layered smectite/illite. The geochemical data shows that in both Sites the majority of the sediments have the characteristics of typical deep sea clay being both of detrital and authigenic origin. In Site 212 these clays with considerable amount of palygorskite and the zeolite clinoptilolite, both of authigenic origin, opaline silica, biogenous CaCOj ,the Fe-Mn oxides and some other detrital minerals together control the bulk chemical composition of the sediments. In Site 213 the clays with large amounts of Fe-Mn oxides and considerable amounts of the zeolite Phillipsite and Palygorskite in small amounts and some other detrital minerals, control the chemical composition of the sediments. The increase in the Ti/Al and Mg/Al ratios with depth in both Sites implies a volcanoclastic input in the bottom sediments probably from the underlying basaltic basement
THE UTILITY OF OIL SHOWS IN THE HYDROCARBON EXPLORATION OF WESTERN GREECE
Authors: Rigakis N. , Nikolaou K. , Marnelis F. , Pakos Th.
Published: June 2018

A great number of oil shows are known in Western Greece, mainly in the Ionian zone, but also in the Preapulian and Gavrovo zones. Most of the wells drilled in the area have also identified oil shows. The systematic study of these oil shows provides a useful tool for the hydrocarbon exploration of this area. First of all the presence of oil shows indicates that oil generation and migration have certainly taken place. Furthermore by their study the petroleum systems of western Greece can be confirmed. Oil shows were analyzed using chemical methods. Because most surface oil shows are biodegraded, the study was mainly based on carbon isotopes measurements and on characteristic biomarker ratios. The oil shows can be classified into five main groups, based on their different compositions, while two of them are separated in two subgroups. This differentiation proves the presence of different source rock horizons, which have generated these oils.
HERMIONE, EVOLUTION OF ATe-BEARING EPITHERMAL MINERALIZATION, ARGOLIS, HELLAS
Authors: Tombros S. , St. Seymour K.
Published: June 2018

The Cu-Te-bearing pyrite deposits of Hermione, Argolis are hosted in Miocenic ophiolites. The ophiolites are overlain by a shale-sandstone formation with intercalations of limestones and manganiferous sedimentary rocks. The ore deposits form irregular lenticular or stratiform ore bodies, and veins. These ore bodies are related to volcanic activity in an arc-related rift at the margins of a palaeocontinent. Late N- to NNE-trending, sinistral, milky quartz-pyrite-calcite veins cut the host ophiolites. Alteration haloes of quartz-calcite, albite-sericitechlorite, and chalcedony-epidote-clay minerals are developed in the lavas as concentric shells, or as envelops that parallel the quartz veins. The telluriumbearing mineralization is developed in two successive stages, characterized by the assemblages: pyrite-(pyrrhotite)-magnetite-chalcopyrite-sphalerite (Stage I) and galena-sphalerite-freibergite-marcasite-chalcocite (Stage II), followed by a supergene stage. The cobaltiferous pyrite-chalcopyrite geothermometer defined two ranges of last-equilibration temperatures: 220° to 250°Cfor Stage I, and 120° to 195°Cfor Stage II. The calculated δ18 Ο and SD compositions of the mineralizing fluids, at 200° and 250°C, reflect the dominance of a magmatic component. The calculated δ SH2S fluid values reveal a magmatic source for the sulphur, with minor contribution from submarine sediments, whereas tellurium is proposed to be derived from a mafic-ultramafic source.
MINERALOGICAL AND GEOCHEMICAL STUDY OF NEOGENE RED BEDS FROM MOUDANIA AND POTIDEA, CHALKIDIKI (MACEDONIA, GREECE)
Authors: Tsirambides A. , Georgiadis I. K. , Papadopoulos A. A. , Ziafetis A. A. , Giouri A. N.
Published: June 2018

The Neogene red beds from Moudania and Potidea (Chalkidiki) are studied in order to find the conditions under which they were formed. They are incoherent coarse grained sands, with poorly sorted grains. Angular to sub-angular rock fragments derived from the adjacent parent rocL· are very common. The red beds are texturally and mineralogically immature. Most of the samples are gravel sands. The extended presence of sand size grains (>0.063 mm) in the samples suggests high intensity of weathering of the parent rocks and rapid transportation and deposition of the weathered materials close to the source area. The detrital minerals present in the whole samples in decreasing abundance are quartz, feldspars (plagioclase + orthoclase), mica (+clay minerals), pyroxene, amphibole, pyrite and halite (except two samples which are rich in calcite). In the <0.063 mm fraction quartz decreases greatly, while feldspars increase. The presence of illite, smectite (+illite/smectite), and chlorite (+vermiculite) in the <0.063 mm fraction is evident. The most likely source minerals for the formation of the studied red beds are quartz, feldspars, micas, and various Fe-Mg silicates, which are primary constituents of the Mesozoic basement igneous and metamorphic rocks predominating in the adjacent area. In the poorly drained lowland of the studied area mean annual air temperature is 16.2° C, mean annual humidity 75%, and mean annual rainfall 59.5 cm. The samples may be considered ferromagnesian and potassic sandstones. The felsic igneous provenance signature is justified for most of the samples. The climate under which these Neogene red beds were formed was warm and semiarid.
Continuous positive airway pressure plus low flow oxygen versus usual care of severe acute cardiogenic pulmonary edema in the pre-hospital setting: A randomised controlled trial
Authors: Austin Michael A. , Wills Karen , Kilpatrick David , Walters E. Haydn
Published: June 2018

Background: Acute cardiogenic pulmonary edema (ACPE) is characterized by acute breathlessness and hypoxia and is associated with poor prognosis. Standard pre-hospital management of ACPE includes high-flow oxygen, nitroglycerin and, in severe cases, assisted ventilation. Patients with ACPE can be supported with newer modalities of non-invasive ventilation, specifically continuous positive airway pressure (CPAP). The aim of this study was to determine whether patients with ACPE treated with CPAP plus low-flow oxygen pre-hospitally have a lower mortality rate than those treated conventionally. 

Methods: This study was a pre-hospital randomised, non-blinded controlled trial conducted July 2009–July 2010. Included were all participants transported by ambulance and admitted to the Royal Hobart Hospital, Tasmania, Australia. The study population was consecutive persons ≥18 years of age with sudden onset of severe respiratory distress, diagnosed as ACPE. Patients were included if they required ventilatory assistance. Patients required a GCS >12 and blood pressure >90 mmHg systolic to safely receive CPAP. The primary outcome was pre- or in-hospital mortality. 

Results: In total, 50 patients were enrolled with mean age of 79.8 (±11.9) years. There were two deaths (8.3%) in the CPAP arm and nine (34.6%) in the control arm (RR, −0.24; 95% CI, 0.06–1.00; p=0.051) with a number needed to treat of 4. CPAP plus low-flow oxygen was significantly less likely to result in respiratory acidosis (mean difference in pH, −0.11; 95% CI, −0.04–−0.17; p=0.002), with elevated pCO2 (mean difference, −10.0 mmHg; 95% CI, −19.2–−0.78; p=0.026). The length of hospital stay was significantly shorter in the surviving patients who received CPAP (ratio of means, 0.45; 95% CI, 0.29–0.70; p≤0.001). 

Discussion: This study, which provides interim results due to early termination of the trial, shows CPAP in the pre-hospital setting for ACPE is practicable and is associated with improved patient outcomes.

Published: June 2018

The aim was to identify the sensitivity of functional methods for studying of respiratory organs in patients with chronic obstructive pulmonary disease (COPD) to a pathogenic environmental impact. There was studied the state of lung function (spirography, bodyplethysmography, pulse oximetry, determination of CO in exhaled air) in 66 patients living in different environmental conditions in Vladivostok and having COPD of different severity. The environmental quality was assessed by the level of air pollution caused by gas components and suspended particulate matter. The meteorological dependence was determined by meteorological parameters on the day of patient’s examination, 1-2 days before and after it. The respiratory system's response to the change in environmental quality was identified using a statistical model that allows predicting the values of the dependent variable Yi (respiratory function) under the impact of the independent variable Xi (environmental factor). It was found out that in mild COPD the methods "determination of CO in exhaled air" and "bodyplethysmography" are the most sensitive to the climatic impact. As the disease progresses, the compensatory mechanisms of respiratory system to climatic effects are violated, while the response of technogenic factors to the pathogenic action increases. The "determining CO in exhaled air" method is the most sensitive to the man-made pollution. Bodyplethysmography allows revealing the formation of "air trapping" and signs of hyperinflation under the influence of unfavorable environmental factors in COPD patients at early stages of the disease. The recommended set of methods makes it possible to assess the risk of COPD progression under the exposure to unfavorable climatic and technogenic factors.

The community-acquired pneumonia (CAP) is a very widespread disease and one of frequent causes of death. The stable relation of seasonal dynamics of indicators of a case rate of CAP with incidence of acute respiratory viral infection and flu becomes perceptible. One of the modern trends of decreasing the incidence and mortality at CAP is immunization with anti-influenza vaccines. Flu immunizations are included in the National calendar of preventive immunization of the Russian Federation. According to official data of the Ministry of Health of the Amur region, in 2015, 2016 and 2017 there were vaccinated 39.7%, 45.4% and 46.2% of population, respectively. CAP case rate in the group immunized with anti-influenza vaccine and in the group not immunized were analyzed. The decrease of the case rate of CAP in patients immunized from flu by 2.4 times in comparison with the people who were not vaccinated from flu was revealed. Against the background of mass vaccination against flu there was a change of clinical implications of CAP: the number of people with mild forms of illness enlarged. Lethality decreased: from 179 immunized people only one patient died, whereas from 393 not immunized people 28 patients had a lethal outcome. The case rate of CAP in people of the senior age groups decreased from 32.2% in 2009-2014 till 21.7% in 2015, from 17.8% in 2016 till 15.9% in 2017. Thus, immunization against flu is followed by an essential decrease of indicators of a case rate of CAP, relief of a disease and improvement of a disease outcome.

The Textbooks of Spanish (L2) Published in Romania Under CommunisThis paper looks at the textbooks of Spanish (L2) published in Romania during the communist regime and designed for the state educational system. More precisely, it investigates the ideological elements and the mechanisms of communist propaganda. The new political regime needed to reform the whole educational system in order to create the “new man” in the spirit of its values and ideology. After the liberalization in the first period of Ceausescu’s regime, Romanians started travelling more and began learning foreign languages other than Russian. The Spanish textbooks published in this context aimed at developing the national identity through texts and visual elements that highlight Romania’s natural beauty, glorious past, economic development, etc. The paratext depicts Romanian factories, representative buildings, monuments, landscapes, but few cultural elements of the Spanish speaking world. The vocabulary is sometimes highly specialised for beginner students. The analysed textbooks do not develop the intercultural competence and aim at highlighting the activity of the Romanian Communist Party.

Outcomes of untreated attention deficit hyperactivity disorder and the mental health nurse
Authors: Nicholson Tom
Published: June 2018

Attention deficit hyperactivity disorder (ADHD) has long been a contentious and polarising issue in mental health care. Mental health nurses are regularly responsible for the care, treatment and care coordination of individuals with a diagnosis of ADHD. This means that mental health nurses are in one of the best positions to have a positive impact on the lives of people with ADHD. This article aims to be a refresher to mental health nurses of the lifetime health outcomes and risks associated with ADHD. This article discusses a multitude of factors, such as increased rates of substance abuse and addiction, higher instances of self-harm and suicide, reduced life expectancy, increased driving risk, poorer educational outcomes, and reduced professional outcomes. The role of the mental health nurse is central in supporting service users to seek appropriate, evidence-based treatment. Improving mental health nurses' understanding and information will enable practitioners to make informed decisions regarding the care and treatment of service users.
The recovery agenda: a blessing or a curse?
Authors: Fernandez Jeff
Published: June 2018

The recovery agenda coupled with a moving of the alcohol and drug budget to local authority has diminished the amount of money provided to service provision. This has been a national picture, with GP-led shared care being the victim of the financial cuts in this area. This paper argues that this is a policy that really should be challenged, as the NHS is diminishing in the field of addictions and is affecting the quality of services provided. Valuable work will be lost for good, such as flexible and effective alcohol detoxifications that enable patients to achieve abstinence from alcohol. This primary care service is important to patients, and alcohol community detoxifications being lost is an example of what is being sacrificed unless professionals recognise that this policy shift has resulted in an overall poorer service and needs to be challenged.

Revision total hip arthroplasty using the Kerboull acetabular reinforcement device for Paprosky type III defects involving the inferior margin of the acetabulum
Authors: Gibon E. , Barut N. , Courpied J-P. , Hamadouche M.
Published: June 2018

Aims

The purpose of this retrospective study was to evaluate the minimum five-year outcome of revision total hip arthroplasty (THA) using the Kerboull acetabular reinforcement device (KARD) in patients with Paprosky type III acetabular defects and destruction of the inferior margin of the acetabulum.

Patients and Methods

We identified 36 patients (37 hips) who underwent revision THA under these circumstances using the KARD, fresh frozen allograft femoral heads, and reconstruction of the inferior margin of the acetabulum. The Merle d’Aubigné system was used for clinical assessment. Serial anteroposterior pelvic radiographs were used to assess migration of the acetabular component.

Results

At a mean follow-up of 8.2 years (5 to 19.3), the mean Merle d’Aubigné score increased from 12.5 (5 to 18) preoperatively to 16.5 (10 to 18) (p < 0.0001). The survival rate at ten years was 95.3% (sd 4.5; 95% confidence interval (CI) 86.4 to 100) and 76.5% (sd 9.9, 95% CI 57.0 to 95.9) using aseptic loosening and radiological loosening as the endpoints, respectively.

Conclusion

These results show that the use of the KARD with reconstruction of the inferior margin of the acetabulum in revision THA is associated with acceptable clinical results and survival at mid-term follow-up with, however, a high rate of migration of the acetabular component of 21.6%.

Alpha-defensin and the Synovasure lateral flow device for the diagnosis of prosthetic joint infection
Authors: Marson B. A. , Deshmukh S. R. , Grindlay D. J. C. , Scammell B. E.
Published: June 2018

Aims

The aim of this review was to evaluate the available literature and to calculate the pooled sensitivity and specificity for the different alpha-defensin test systems that may be used to diagnose prosthetic joint infection (PJI).

Materials and Methods

Studies using alpha-defensin or Synovasure (Zimmer Biomet, Warsaw, Indiana) to diagnose PJI were identified from systematic searches of electronic databases. The quality of the studies was evaluated using the Quality Assessment of Studies of Diagnostic Accuracy (QUADAS) tool. Meta-analysis was completed using a bivariate model.

Results

A total of 11 eligible studies were included. The median QUADAS score was 13 (interquartile range 13 to 13) out of 14. Significant conflicts of interest were identified in five studies. The pooled sensitivity for the laboratory alpha-defensin test was 0.95 (95% confidence interval (CI) 0.91 to 0.98) and the pooled specificity was 0.97 (95% CI 0.95 to 0.98) for four studies with a threshold level of 5.2 mgl-1 The pooled sensitivity for the lateral flow cassette test was 0.85 (95% CI 0.74 to 0.92) and the pooled specificity was 0.90 (95% CI 0.91 to 0.98). There was a statistically significant difference in sensitivity (p = 0.019), but not specificity (p = 0.47).

Conclusion

Laboratory-based alpha-defensin testing remains a promising tool for diagnosing PJI. The lateral flow cassette has a significantly lower performance and pooled results are comparable to the leucocyte esterase test. Further studies are required before the widespread adoption of the lateral flow cassette alpha-defensin test. Cite this article: Bone Joint J 2018;100-B:703–11.

Este artigo visa caracterizar as relações entre Motivação para o Trabalho, Comprometimento Afetivo e Exaustão Emocional, investigando trabalhadores bancários. Foram aplicadas três escalas, a Escala Multidimensional de Motivação para o Trabalho, a Escala de Comprometimento Organizacional Afetivo e a Escala de Caracterização do Burnout. A pesquisa de abordagem quantitativa e descritiva teve 361 respondentes de uma instituição bancária do Rio Grande do Sul. Tabulação cruzada, teste qui-quadrado de Pearson, média aritmética, desvio-padrão e Teste T foram aplicados. Os principais resultados apontam que há predominância de aspectos motivacionais relativos ao trabalho em todos os fatores da motivação e possuem, em relação aos trabalhadores de outras organizações, motivação controlada superior, porém menor motivação autônoma. O Comprometimento Afetivo é mais elevado na comparação com outras organizações e a Exaustão Emocional é tendencialmente baixa, ainda que entre trabalhadores das agências, em comparação com os da administração central do banco, os resultados de exaustão sejam maiores. Tais resultados devem ser considerados pela área de Gestão de Pessoas ao elaborar intervenções para promoção de saúde dos trabalhadores, bem como orientar ações de liderança no sentido de promoverem maior autonomia nas relações de trabalho.

Este trabalho objetiva analisar o estado de inocência como direito fundamental sob as perspectivas de sua natureza, conteúdo, estrutura normativa e funcionalidade, tendo a sociedade da informação, ou sociedade em rede, como paradigma. O problema de pesquisa é se a exposição pública pelos veículos de comunicação de massa de casos penais pendentes de julgamento definitivo viola ou não o estado de inocência. E, em caso afirmativo, como a estrutura normativa é atingida e quem é o destinatário da norma: apenas o Estado ou também os particulares. O estudo baseia-se na jurisprudência dos tribunais internacionais de direitos humanos como método de abordagem, analisando, dialeticamente, os possíveis limites à liberdade de expressão frente ao estado de inocência. A conclusão é de que o estado de inocência, embora tenha natureza processual, é direito-garantia fundamental com eficácia vertical em relação aos media, sob o aspecto de norma de tratamento.

In this paper, we identify the key parameters to consider in a decision model on internationalization of operations. In order to propose these parameters, the GLOBOPE framework was adopted as the basis of this work. This framework contemplates the three commonest challenges of global operations configuration for industrial manufacturing companies in an internationalization process, which are: new facility implementation (NFI); global suppliers’ network development (GSND); multisite production network configuration. A set of suitable parameters is herein provided for NFI and GSND in the analysis stage from strategic, tactical and operational decision levels. These parameters could be used in the future as a basis for the development of quantitative tools for decision making on the internationalization of operations.

In the business world, the management of an organization calls for the development of information to support decisions. However, this is not a reality for a significant part of micro and small enterprises in Brazil, as several studies have shown. On this theme, with a focus on individual micro-entrepreneurs, the present study investigated how these businesspeople manage their finances and development. Methodologically, the study was supported by field research with 21 entrepreneurs in different business segments from the city of Volta Redonda (Rio de Janeiro state). Results indicated that 19% of respondents do not control cash flow and 76% do not analyze their financial results. Of those that use some kind of control, 67% monitor their finances by handwritten notes in notebooks. Regarding the sales forecast, less than half of the surveyed people do this type of control. Therefore, the surveyed micro-entrepreneurs need to develop financial and accounting management systems, focusing on a better financial control of their businesses. Although not conclusive, we believe the results obtained are related to the respondents’ low level of education.

Murder is essentially the culmination of an aggression which is still be a blind spot for the civilization of mankind. The incidence is quite high, but studies that specifically review it are still small. This research intends to deepen the crime of murder by focusing on causal factors, psychological dynamics and the impact of murder behavior on the perpetrators. Adolescents were chosen as subjects because murder cases conducted by teenagers also showed considerable numbers. The study was designed using a qualitative approach, a phenomenology of forensics which is a phenomenological approach that specifically reveals forensic cases related to murder offenses. Eight subjects participated in research conducted at the Kutoarjo Child Prison. Data in this study were collected through obeservation and interview with subject, psychological testing, home visit, and completed by an interview with prison officer and prison document data. The collected data interview is then analyzed using data explication method. This study finds that the dynamics of family factor interaction, social environment, friends, drug and alcohol abuse, socioeconomic status, education, individual psychological condition, availability of weapons, and the characteristics of the victim causing the killing behavior in adolescents. The impact of murder for the offender varies, depends on the background of the case.

The increasing number of traffic accident is caused by the decreasing of driver situational awareness. Divided attention is one of several factors that affect situation awareness. This experiment was to study the effects of listening to the music or reading short message sent to participant’s mobile phone on participant’s situational awareness while they drove car simulator. Thirty subjects were randomly divided into two groups, namely: (a) music group. The subjects were asked to listen to Ed Sheeran pop music when they drove city car simulator, and (b) mobile phone group. In this condition the subjects received and replied short message on their mobile phones at third, fifth, eighth, and tenth minutes during driving car simulator. Situational awareness was measured by SAGAT (Situation Awareness Global Assessment Technique). The simulation was stopped when SAGAT questionnaire was distributed to the subjects at fifth and tenth minutes. The t test statistical analysis showed that there was a significant difference in situation awareness between the two groups (t= 5.750; p= .001). Music group showed higher situation awareness than mobile phone group. The use of mobile phone while driving is more distracting attention than listening to music.
KONSEP DESAIN EKOLOGIS RUANG TERBUKA HIJAU DI SUDIRMAN CENTRAL BUSINESS DISTRICT (SCBD) SEBAGAI HABITAT BURUNG

Published: June 2018

Landscape in Central Business District (CBD) is part of urban green spaces which have a role to enhance ecological value of the city, one of them is Sudirman Central Business Distict. The existence of birds will strengthen the ecological functions of the city. The aim of this study is to design the green spaces as bird habitat. Lot 17 SCBD has the potential to be developed as a bird sanctuary protection area divided into two areas: nesting and transition area. The method that will be used for this research is descriptive analysis through site survey and literature. The concept that used is eco-friendly bird park, a park that is able to present the directly or indirectly interaction between humans and birds without reducing the fulfillment of ecological functions of the park. The design concept applies the deco art style that has a dynamic impression and a pliable flexible shape. The dynamic impression will be applied in the form of arches on the park patterns and circulations to create natural impression. The existence of Lot 17 park can soften the surrounding condition, which is a storey building. Visitors can observe birds on tree canopies using binoculars that is placed on the deck view and canopy tree rail.
The forkhead domain hinge-loop plays a pivotal role in DNA binding and transcriptional activity of FOXP2

Published: June 2018

Forkhead box (FOX) proteins are a ubiquitously expressed family of transcription factors that regulate the development and differentiation of a wide range of tissues in animals. The FOXP subfamily members are the only known FOX proteins capable of forming domain-swapped forkhead domain (FHD) dimers. This is proposed to be due to an evolutionary mutation (P539A) that lies in the FHD hinge loop, a key region thought to fine-tune DNA sequence specificity in the FOX transcription factors. Considering the importance of the hinge loop in both the dimerisation mechanism of the FOXP FHD and its role in tuning DNA binding, a detailed investigation into the implications of mutations within this region could provide important insight into the evolution of the FOX family. Isothermal titration calorimetry and hydrogen exchange mass spectroscopy were used to study the thermodynamic binding signature and changes in backbone dynamics of FOXP2 FHD DNA binding. Dual luciferase reporter assays were performed to study the effect that the hinge-loop mutation has on FOXP2 transcriptional activity in vivo. We demonstrate that the change in dynamics of the hinge-loop region of FOXP2 alters the energetics and mechanism of DNA binding highlighting the critical role of hinge loop mutations in regulating DNA binding characteristics of the FOX proteins.
Resolving abstract anaphors in Spanish discourse: Underspecification and mereological structures
Authors: Zulaica Hernández Iker
Published: June 2018

Anaphoric underspecification involves multiple potential candidate antecedents for an anaphoric expression. In abstract object anaphora, where linguistic antecedents are clauses, sentences and larger fragments of discourse, the source of referential underspecification is commonly found at the propositional level. Thus, underspecified abstract anaphors have multiple antecedents of a higher-order nature (i.e., propositions and events). Following previous research on anaphoric underspecification with nominal antecedents, I propose a hypothetical three-step process toward the resolution of underspecified abstract object anaphors by hearers in discourse: (i) creation of a complex abstract object with a mereological structure that includes all potential interpretations for an anaphor, (ii) recognition of the thematic connection among propositions intended by the speaker in the form of a specific rhetorical relation, and 3) resolution of the abstract anaphor. Potential antecedents for any underspecified abstract anaphor may include atomic propositions and complex abstract referents that result from a merged interpretation of several propositions that are thematically connected. Provided that it is available, I claim that such a merged interpretation, which is part of the mereological structure, is the preferred interpretation as it is generally interpreted as part of a general purpose by the speaker, in addition to contributing to the thematic coherence of discourse.
Meaning change in Chinese: A numeral phrase construction from adjectives to superlatives to definite descriptions
Authors: Jin Dawei , Chen Jun
Published: June 2018

This paper analyzes a hitherto unnoticed semantic change process in Chinese, in which lexical (adjectival) materials develop into superlative operators, and subsequently turn into definiteness markers. Our analysis focuses on the semantic factors that underlie this meaning change trajectory. Specifically, we argue that frequent association of gradable adjectives with superlative implication leads to pragmatic strengthening in which the superlative implication conventionally enters the literal meaning. Furthermore, we show that a further change in the extension of the nominal part of superlative phrases leads to a maximality reanalysis that is compatible with the semantics of definite NPs. This paper contributes to the burgeoning field of applying truth-conditional semantics to theories of grammaticalization.

Published: June 2018

This paper presents a novel approach to design and optimize geometric nonlinear springs for wideband vibration energy harvesting. To this end, we designed a spring with several folds to increase its geometric nonlinearities. A numerical analysis is performed using the Finite Element Method to estimate its quadratic and cubic spring stiffness. A nonlinear effective spring constant is then calculated for different values of the main folding angle. We demonstrate that this angle can increase nonlinearities within the structure resulting in higher bandwidths, and that it is possible to control the behavior of the system to have softening-type or hardening-type response depending on the choice of the folding angle. Based on the Lindstedt-Poincaré perturbation technique, a first order approximation is determined to predict the frequency-response of the system. In order to validate the perturbation analysis, numerical solutions based on long-time integration method and mixed VHDL-AMS/Spice simulations are presented. Finally, this method is applied to a previously published device and shows a good agreement with experiments.
