Rol de la calidad de vida en el consumo de riesgo de alcohol: ¿debe ser una variable más relevante en cualquier investigación en este campo
Authors: López-Pelayo Hugo , Oliveras Clara , Segura Lidia , Colom Joan , Díaz Estela , Wallace Paul , Gual Antoni
Published: July 2018

A partir de los datos basales del estudio EFAR-Spain para la validación de una intervención breve en línea en consumidores de riesgo de alcohol facilitado desde atención primaria nos hemos propuesto explorar la relación entre la calidad de vida (medida a través de la escala EQ-5D-5L ) y el patrón de consumo de alcohol (a partir del AUDIT). Utilizamos como variable principal dependiente la calidad de vida y las seis diferentes dimensiones de la misma (ansiedad/depresión, escala analógica-visual, dolor/incomodidad, movilidad, autocuidado, actividades diarias), y como variables independientes la puntuación en el AUDIT y los datos sociodemográficos. El análisis multivariante confirmó la asociación estadística de la calidad de vida (regresión linear B-0.25 IC95%-0.01 a -0.04), la subescala de depresión/ansiedad (regresión logística: OR 1.10 IC95% 1.08-1.22), y la subescala analógica-visual (regresión lineal B-0.27 IC95% -1.25 a -0.500) con puntuación total del AUDIT de forma independiente de los factores sociodemográficos. Teniendo en cuenta que en la asistencia del paciente con problemas de alcohol la reducción de consumo de alcohol puede ser un objetivo terapéutico alcanzable y respetuoso con la ética profesional en los casos leves y moderados y que la auto-evaluación del patrón de consumo de alcohol por parte del paciente no está exenta de minimizaciones en las cantidades y frecuencias, tal vez podría ser adecuado evaluar la evolución de nuestros pacientes en función de los cambios en la calidad de vida como respuesta al tratamiento. Abstract Using basal data from EFAR-Spain (A randomised controlled non-inferiority trial of primary care-based facilitated access to an alcohol reduction website) we explored the relationship between quality of life (QoL, as evaluated by EQ-5D-5L) and pattern of alcohol use (as evaluated by AUDIT) . Multivariate regression analyses were conducted using total QoL index and QoL six dimensions (anxiety/depression, Visual Analogue Scale (VAS), pain, mobility, self-care, daily activities) as dependent variables and AUDIT score and sociodemographic data as independent variables. Adjusting for sociodemographic data, AUDIT score was a statiscally significant predictor of overall QoL (lineal regression B-0.25 95% CI -0.04 to -0.01), anxiety/depression (logistic regression OR 1.10 95% CI 1.08-1.22) and health VAS (lineal regression B-0.27 95% CI -1.25 to -0.500). Since reducing alcohol intake can be a reasonable and ethically correct therapeutic objective in mild and moderate alcohol use disorders and since alcohol use pattern self-assessment has several limitations, perhaps assessing changes in QoL over time could be useful to monitor our patients recovery.

The influence of cigarrette-smoking when choosing a partner for a casual, intimate relationship
Authors: Amigo Vázquez Isaac , Álvarez Fernández María , Secades-Villa Roberto
Published: July 2018

Attitudes towards smoking have changes in recent years and it would appear that, whereas for many years cigarette-smoking was associated with a certain physical attractive and sex appeal, this may no longer be the case. The aim of this study is to analyse whether smoking has a favourable or unfavourable effect when approaching a potential partner for a casual, intimate relationship. A total of 597 participants (293 non-smokers, 163 ex-smokers and 141 smokers) were recruited by means of intentional sampling to participate in this study, using the “snowball” technique. Three different ad hoc questionnaires were used for each of the groups of participants The results showed that, in the majority of the sample studied,  smoking had a dissuasive effect with regard to establishing a relationship of this type, both amongst men and women and in the different age groups. For this type of relationship, particiants prefered non-smokers people. These results could be of great value when developing preventative and therapeutic interventions focused on the habit of smoking.
Desmotivadora evolución de la desconexión asimétrica del Núcleo Accumbens en el trastorno por consumo de cocaína: un punto de vista traslacional

Published: July 2018

Background. Experimental asymmetrical disconnection in animals is a lesion technique used to demonstrate the involvement of specific brain circuits in complex behaviors. Using this surgical technique it has been demonstrated that cortico-limbic-striatal circuits, involving medial prefrontal cortex (mPFC), basolateral amygdala (BLA), and nucleus accumbens (Nacb), regulate decision-making processes. In particular, disruption of Nacb and BLA communication impairs motivated behavior. In addition, disconnections between the BLA and mPFC increase choice of riskier options, suggesting that this circuit facilitates tracking of actions and outcomes to temper urges for riskier rewards and to maintain effort. Case Description. A young patient with disruptive aggressive behaviors and cocaine abuse problems was diagnosed from “impulse control dysfunction” and “limbic dysfunction syndrome”. Neuroimaging tests indicated atrophy of left hemisphere, and moderate general reduction in brain metabolism. Surgical intervention, very similar to the experimental technique previously described, was employed. Thermal coagulation lesions were targeted at left hemisphere anterior cingulate (AC), anterior capsula (ALIC), and stria terminalis. In the right hemisphere targets were ALIC and amygdala. Two months later, after relapse of aggressivity, a second surgery extended previous lesions in left ALIC and AC in the right hemisphere. Neuroimages after 5 and 15 years demonstrate the extent of those lesions. Conclusions. Recent neuropsychological tests in this patient that assessed frontal and striatal functions show high impulsivity, impairment of planning processes and difficulties in cost/benefit decision making compared with normative samples. There is evidence showing that addiction and schizophrenia have very little improvements from surgical interventions. Moreover, combining more than one brain target may make outcomes worse.

Published: July 2018

Contrariamente a lo que ocurre con el resto de sustancias todavía no se han logrado disminuir los niveles de consumo de cannabis, que sigue siendo la droga ilegal más consumida entre los adolescentes españoles. El objetivo de este estudio consiste en actualizar los niveles de consumo (incorporando la franja de edad de 12-13 años), estimar los consumos propiamente de riesgo y analizar las posibles variables asociadas. Para ello se ha utilizado una metodología correlacional consistente en la realización de una encuesta a estudiantes de ESO y Bachillerato de la comunidad autónoma de Galicia (España) en el año 2016. La muestra final estuvo compuesta por 3.882 adolescentes gallegos de entre 12 y 18 años (M = 14,52 y DT = 1,72). Los resultados obtenidos revelan que a día de hoy es ya mayor el porcentaje de adolescentes que consumen tabaco y cannabis que únicamente tabaco (12,7% vs 10,5%) y que ello no sólo implica una mayor probabilidad de consumir otras sustancias ilegales, sino también de desarrollar un patrón consumo de alcohol de riesgo, de Binge Drinking o incluso de experimentar un Uso Problemático de Internet o de ciberacoso. Las variables personales como la autoestima, la asertividad, las habilidades sociales o la impulsividad tienen una capacidad explicativa realmente débil, en comparación con otras variables vinculadas al establecimiento de normas y límites por parte de los padres. Una de las principales conclusiones de este trabajo es la necesidad de adoptar un enfoque de prevención integral.
Exercise addiction measure through the Exercise Addiction Inventory (EAI) and health in habitual exercisers. A systematic review and meta-analysis
Authors: Simón Grima Javier Simón , Estrada-Marcén Nerea , Montero-Marín Jesús
Published: July 2018

Research on physical exercise addiction is becoming more frequent due to the importance of excessive physical activity on health in general. Different studies have investigated the prevalence of risk of exercise addiction (REA) and its consequences. Furthermore, there exist a series of contradictions regarding the relationship between REA and other variables associated with physical training. One goal of this systematic review and meta-analysis consists of analysing possible differences in prevalence, age, general health (mental and physical quality of life, eating disorders) and physical training (hours/week) between groups with REA and non-addicted groups. The Exercise Addiction Inventory (EAI) was used to undertake this research. Research was carried out in electronic databases such as Pubmed, SPORTDiscus or Scopus. Inclusion criteria: Studies were eligible as long as participants were measured with EAI, results showed prevalence of REA and/or EAI score, and the study was observational. Twenty studies met the established eligibility criteria for inclusion in the systematic review, whereas seventeen studies were included in the meta-analysis. Regarding mental quality of life, results showed lower values for the exercise addiction risk group, compared with the non-addicted group. The exercise addiction group was younger than the non-addicted group and dedicated more weekly hours to physical training. Subjects with REA have a lower health profile than those with non-REA. However, more research is required, given the lack of consensus on how to measure exercise addiction and the scarce number of studies to date.

Published: July 2018

Detection of early stage corrosion on slender steel members is crucial for preventing buckling failures of steel structures. An active photoacoustic fiber optic sensors (FOS) system has been reported for early stage steel corrosion detection of steel plates and rebars using surface ultrasonic waves. The objective of this paper is to investigate the surface corrosion/rust detection problem on steel rods using numerically simulated surface ultrasonic waves. The finite element method (FEM) is applied in simulating the propagation of ultrasonic waves on steel rod models. Transmission mode of damage detection is adopted, in which one source (transmitter) and one sensor (receiver) are considered. In this research, radial displacements at the receiver were simulated and analyzed by short-time Fourier transform (STFT) for detecting, locating, and quantifying a surface rust located between the transmitter and the receiver. From our time domain and frequency domain analyses, it is found that the presence, location, and dimensions (length, width, and depth) of surface rust can be estimated by ultrasonic waves propagating through the surface rust.

Electricity Price of Hybrid Power System and Decision Making of Renewable Energy Investment Capacity
Authors: Xie Jiaping , Zhang Weisi , Xia Yu , Liang Ling , Kong Lingcheng
Published: July 2018

In the existing electricity market, the traditional power suppliers and renewable energy generators coexist in the power supply side. In the power supply side, renewable energy generators generate power by wind and other natural conditions, leading renewable energy output a certain randomness. However, the low marginal generating cost and the reduction of carbon emissions, and thus brings a certain advantage for renewable energy compared to alternative energy. Electricity, as a special commodity, stable and adequate power supply is a necessary guarantee for economic and social development. Power shortage situation is not allowed in the power system, and the extra power needs to be handled for the purpose of safety. In this paper, the hybrid power generated by renewable energy generators and traditional energy generators is used as power supply, and then the electricity market sells hybrid power to electricity consumers, the hybrid power system determines the optimal daytime price, nighttime price, and the optimal installed capacity of the renewable energy suppliers. We find that the installed capacity of renewable energy increases first and then decreases with the increase of the price sensitivity coefficient of traditional energy supply. Electricity demand is negatively related to electricity price in the current period, and is positively related to price in the other period. The average price of day and night is only related to the total potential demand of day and night and the total generation probability of renewable energy. The price difference between daytime and nighttime is positively related to potential electricity demand, and negatively related to the sensitivity coefficient of electricity price.

Authors: Luthfiana Profita Sumunar , Nasrudin Nasrudin
Published: July 2018

Gross Domestic Product (GDP) is considered as the best measure of economicperformance. However, in Indonesia, the GDP is presented in quarterly aggregate value.As a result, the monthly economic outlook is unknown, and analysis with other monthlyeconomic variables becomes limited. Therefore, this study will disaggregate quarterlyGDP into monthly GDP and its forecasting by using one of the coincident indicatorswhich are monthly Production Index of Large and Medium Manufacturing (industrialproduction index). Disaggregation is done on National GDP data of Indonesia period2000/I to 2016 / IV, whereas forecasting is made on monthly and quarterly GDP 2017.This study uses a combination of the simple linear regression model and ARIMA modelwith some modifications. The disaggregation result indicates that the monthly GDPmoves volatile and has a different pattern between quarters. Also, the monthly GDPdisaggregation and forecasting are proven that can be used by industrial productionindex that becomes a coincident indicator. GDP 2017 shows that the highest quarterlyGDP will have occurred in the third quarter, whereas the highest monthly GDP willhave occurred in June (second quarter). The result of disaggregation can be used furtherto the study of economic outlook will be more comprehensive.
The likelihood value of residual risk estimation in the management of enterprise risk
Authors: Kountur Ronny
Published: July 2018

A model for estimating the likelihood value of residual risk (Y) is introduced. The model consists of three independent variables: the likelihood value of risk before risk treatment (X1), the quality of risk treatment (X2), and the appropriateness of risk treatment (X3). An experimental research design with a multiple linear regression analysis was used in the estimation. All independent variables, the likelihood value of risk before treatment, the quality of risk treatment, and the appropriateness of risk treatment, can be significantly used to estimate the likelihood value of residual risk. Since no model of estimating residual risk of likelihood had been introduced yet, the findings of this study provide significant contribution to firms or organizations that need to assess the likelihood value of residual risks.

Chaperones and Their Role in Telomerase Ribonucleoprotein Biogenesis and Telomere Maintenance
Authors: Viviescas Maria Alejandra , Cano Maria Isabel Nogueira , Segatto Marcela
Published: July 2018

Telomere length maintenance is important for genome stability and cell division. In most eukaryotes, telomeres are maintained by the telomerase ribonucleoprotein (RNP) complex, minimally composed of the Telomerase Reverse Transcriptase (TERT) and the telomerase RNA (TER) components. In addition to TERT and TER, other protein subunits are part of the complex and are involved in telomerase regulation, assembly, disassembly, and degradation. Among them are some molecular chaperones such as Hsp90 and its co-chaperone p23 which are found associated with the telomerase RNP complex in humans, yeast and probably in protozoa. Hsp90 and p23 are necessary for the telomerase RNP assembly and enzyme activity. In budding yeast, the Hsp90 homolog (Hsp82) is also responsible for the association and dissociation of telomerase from the telomeric DNA by its direct interaction with a telomere end-binding protein (Cdc13), responsible for regulating telomerase access to telomeres. In addition, AAA+ ATPases, such as Pontin and Reptin, which are also considered chaperone- like proteins, associate with the human telomerase complex by the direct interaction of Pontin with TERT and dyskerin. They are probably responsible for telomerase RNP assembly since their depletion impairs the accumulation of the complex. Moreover, various RNA chaperones, are also pivotal in the assembly and migration of the mature telomerase complex and complex intermediates. In this review, we will focus on the importance of molecular chaperones for telomerase RNP biogenesis and how they impact telomere length maintenance and cellular homeostasis.

Crinnolines can serve as unique and versatile class of heterocycles especially in fields related
to synthetic and pharmaceutical chemistry owing to their potent biological activities. They possess diversity
of pharmaceutical activities as anticancer, antibacterial, anti-inflammatory, anti-allergic as well
as anti-hypertensive activities. Since the first synthesis of cinnoline by Richter (1883) numerous protocols
for their synthesis have been developed utilizing arenediazonium salts, aryl hydrazines and arylhydhydrazones
precursors. Recently metal catalyzed C-C and C-N bond formation reactions have
emerged as efficient tools for synthesis of cinnoline derivatives. This review aims to focus on the recent
synthetic routes used for the synthesis of cinnoline derivatives. An effort has been carried out to provide
an overview of practical methods for preparing cinnolines. Furthermore the reaction mechanisms have
been described in brief.
Inhibition of Yeast Growth by Tryptamine and Recovery with Tryptophan
Authors: Kadkol Chandrika , Macreadie Ian
Published: July 2018

Background:

Tryptamine, a biogenic monoamine that is present in trace levels in the mammalian central nervous system, has probable roles as a neurotransmitter and/or a neuromodulator and may be associated with various neuropsychiatric disorders. One of the ways tryptamine may affect the body is by the competitive inhibition of the attachment of tryptophan to tryptophanyl tRNA synthetases.

Methods:

This study has explored the effects of tryptamine on growth of six yeast species (Saccharomyces cerevisiae, Candida glabrata, C. krusei, C. dubliniensis, C. tropicalis and C. lusitaniae) in media with glucose or ethanol as the carbon source, as well as recovery of growth inhibition by the addition of tryptophan.

Results:

Tryptamine was found to have an inhibitory effect on respiratory growth of all yeast species when grown with ethanol as the carbon source. Tryptamine also inhibited fermentative growth of Saccharomyces cerevisiae, C. krusei and C. tropicalis with glucose as the carbon source. In most cases the inhibitory effects were reduced by added tryptophan.

Conclusion:

The results obtained in this study are consistent with tryptamine competing with tryptophan to bind mitochondrial and cytoplasmic tryptophanyl tRNA synthetases in yeast: effects on mitochondrial and cytoplasmic protein synthesis can be studied as a function of growth with glucose or ethanol as a carbon source. Of the yeast species tested, there is variation in the sensitivity to tryptamine and the rescue by tryptophan. The current study suggests appropriate yeast strains and approaches for further studies.
Creating Gameful Design in mHealth: A Participatory Co-Design Approach (Preprint)
Authors: Jessen Stian , Mirkovic Jelena , Ruland Cornelia M
Published: July 2018

BACKGROUND

Gameful designs (gamification), using design pieces and concepts typically found in the world of games, is a promising approach to increase users’ engagement with, and adherence to, electronic health and mobile health (mHealth) tools. Even though both identifying and addressing users’ requirements and needs are important steps of designing information technology tools, little is known about the users’ requirements and preferences for gameful designs in the context of self-management of chronic conditions.

OBJECTIVE

This study aimed to present findings as well as the applied methods and design activities from a series of participatory design workshops with patients with chronic conditions, organized to generate and explore user needs, preferences, and ideas to the implementation of gameful designs in an mHealth self-management app.

METHODS

We conducted three sets of two consecutive co-design workshops with a total of 22 participants with chronic conditions. In the workshops, we applied participatory design methods to engage users in different activities such as design games, scenario making, prototyping, and sticky notes exercises. The workshops were filmed, and the participants’ interactions, written products, ideas, and suggestions were analyzed thematically.

RESULTS

During the workshops, the participants identified a wide range of requirements, concerns, and ideas for using the gameful elements in the design of an mHealth self-management app. Overall inputs on the design of the app concerned aspects such as providing a positive user experience by promoting collaboration and not visibly losing to someone or by designing all feedback in the app to be uplifting and positive. The participants provided both general inputs (regarding the degree of competitiveness, use of rewards, or possibilities for customization) and specific inputs (such as being able to customize the look of their avatars or by having rewards that can be exchanged for real-world goods in a gift shop). However, inputs also highlighted the importance of making tools that provide features that are meaningful and motivating on their own and do not only have to rely on gameful design features to make people use them.

CONCLUSIONS

The main contribution in this study was users’ contextualized and richly described needs and requirements for gamefully designed mHealth tools for supporting chronic patients in self-management as well as the methods and techniques used to facilitate and support both the participant’s creativity and communication of ideas and inputs. The range, variety, and depth of the inputs from our participants also showed the appropriateness of our design approach and activities. These findings may be combined with literature and relevant theories to further inform in the selection and application of gameful designs in mHealth apps, or they can be used as a starting point for conducting more participatory workshops focused on co-designing gameful health apps.
Exploring the role of the business rescue practitioner in rescuing a financially distressed company
Authors: Mpofu Kudzai , Nwafor Anthony O. , Selala Koboro J.
Published: July 2018

The emphasis on corporate sustainability as against liquidation in the South African Companies Act 71 of 2008 creates an important figure in the person of the business rescue practitioner. The practitioner in that capacity supplants the board and is insulated from the relevant elements of shareholder control in the discharge of the task of rescuing the financially distressed company. The article interrogates, through doctrinal approach, the efficacy of the statutory provisions relating to the role of the business rescue practitioner in the business rescue process and argues against the disqualification of juristic persons from appointment as business rescue practitioners. While respecting the subjective decision of the practitioner in the preparation of the rescue plan, the paper considers that such subjective decision should withstand some level of objective assessment to enjoy credibility, just as the practitioner should conform to a high level of judicial scrutiny as an officer of the court to be absolved from any liability arising from a breach of duty.

Published: July 2018

Perovskite ceramics (Ba0.6Pb0.4)TiO3 modified with PbO-B2O3-Al2O3-WO3 special
glass was prepared with the conventional mixed oxide method. X-ray
diffraction analysis (XRD) of the obtained materials confirmed singlephase
and pure tetragonal structure. The Rietveld method was used to determine
unit cell parameters. Uniform deformation of the tetragonal parameter was
observed with addition of the glass. Dielectric measurements revealed the
remarkable influence of special glass admixture on the value of dielectric
permittivity and dielectric losses, as well as the Curie temperature.
However, the most important achievement of the investigations is obtaining a
significant PTCR effect in the sample containing 6 wt.% of special glass
admixture.
Impact of B2O3 and La2O3 addition on structural, mechanical and biological properties of hydroxyapatite
Authors: Khoshsima Sina , Alshemary Ammar , Tezcaner Aysen , Surdem Sedat , Evis Zafer
Published: July 2018

In this study, hydroxyapatite-B2O3-La2O3 composites (with ? 20 wt.%B2O3 and ?
2 wt.% La2O3) were synthesized via wet precipitation method and calcined at
1100?C for 1 h. X-ray diffraction (XRD) analysis revealed the existence of
the pure hydroxyapatite (HA) phase with high crystallinity. Characteristic
absorption bands of HA were also observed in Fourier transform infrared
spectra. Furthermore, scanning electron microscopy images demonstrated that
the addition of B2O3 and La2O3 into HA enhanced the particle growth.
Mechanical properties of the composites were studied by diametral tensile
test and the results showed that incorporation of 10 wt.% B2O3 and 2 wt.%
La2O3 led to a 39% increase in tensile strength (compared to the pure HA).
In vitro cytocompatibility of HA-B2O3-La2O3 composites was investigated
using Osteosarcoma Cell Lines (Saos-2). Incorporation of B2O3 and La2O3 into
HA had no toxic effect towards the cells. Based on its tensile strength
properties and biological response, composite of 88 wt.% HA, 10 wt.% B2O3
and 2 wt.% La2O3 was suggested as a promising composite for bone tissue
engineering applications.

Brief information about the new BiJFet array chip (AC) MH2XA030 intended for
accelerated creation of analog integrated circuits (IC), which retain their
performance under the influence of penetrating radiation and extremely low
temperatures (up to minus 197??) is presented. The features of schematic
design of two types of DDOAs (OAmp3, OAmp4) are considered. The
recommendations on the schematic design of the DDOA are developed taking
into account the static characteristics of the field effect and bipolar
transistors of the AC under the influence of low temperatures. The
amplitude-frequency response of the DDOA and the dependence of the noise
voltage on the frequency of Fourier density are given. At a temperature of
-197?? cryogenic amplifiers OAmp3 (OAmp4) are characterized by the following
parameters: the current consumption is less than 500 ?A, the input current
is less than 1 fA, the voltage gain is more than 50.000 (200.000), the
offset voltage is less than 200 (60) ?V. The results of the circuit
simulation of the instrumentation amplifier based on DDOA OAmp3 are
presented.
The morning after: Nuit Debout - debates, practice and theory
Authors: Biresev Ana
Published: July 2018

This paper analyses the French protest movement Nuit Debout that started on
March 31, 2016 at the Place de la R?publique in Paris. The protest is
approached from the perspective of the debate that took place in French
media on how to define of the enemy, goals, preferred strategy and
organizational model, then, from the angle of the protest practice itself,
and finally, that of the sociology of Luc Boltanski. The article focuses on
two issues that got the most attention from the protesters and the public -
convergence of struggles and prefigurative politics. Both are discussed from
the vantage point of Boltanski?s study of contemporary capitalism in order
to provide propositions for further development of the ideas that Nuit
Debout tried to put into practice. The aim is to highlight the importance of
everyday practices and experiences of injustice for today?s critique of
capitalism and the convergence of struggles, as well as to assess the role
that experimenting with participatory democracy and horizontality, present
in the latest social movements as well as in Nuit De bout, plays in
processes of confluence of those experiences and ?ordinary? critiques and
their transformation into program, strategy and action.
“Internal colonialism” - a contribution to the history of the concept
Authors: Subotic Milan
Published: July 2018

Starting from the renewed interest into the concept of the ?internal
colonialism? within the contemporary ?postcolonial studies?, this paper
discusses the origin and the meaning of the concept in various theoretical
traditions and scientific fields. The first part interprets ?internal
colonialism? and ?internal colonization? from the perspective of historical
and political-economic debates on the Russian and Soviet imperial structure,
and from the sociological critique of the social development of the Stalinist
epoch. The second part is dedicated to the analysis of the effect and
limitations of the use of the concept in interpreting the integrative
(French) nationalism and interpreting the reactive, (Celtic) minority
nationalisms within Great Britain. In the final part the author has
interpreted the meanings that ?internal colonialism? had in sociological
analysis of the states of the ?capitalist periphery? (Latin America) and in
the political discourse of the ?New Left? protest movements in the USA as a
?capitalist metropolis?. By pointing out the close connection of the analyses
of ?colonialism in one country? with Marxist tradition of research into class
structure of society, the author concludes that the concept of ?internal
colonialism? today is primarily used as a metaphor that finds a useful
application within the ?cultural studies?. From that point of view, the
history of the concept illustrates the change of the theoretical discourse
that characterises social sciences after the ?cultural turn?.
Examination of the structure of the traditional/secular-rational and survival/self-expression value dimensions in the model of Ronald Inglehart: The case of Serbia

The paper examines applicability of Inglehart?s model of dimensions of
traditional/secular-rational values and survival/self expresion values,
based on European Values Study data, conducted in Serbia in 2008. Dimensions
of values are extracted by applying nonlinear principal component analysis,
with asigning ordinal level of analysis. We present three-dimensional
solution which separates dimension of survival/self expresion values into
two dimensions. The deviations from the two-dimensional model were
interpreted in accordance with the theory of revised modernization and
thesis about value change in dependance of sociocultural paths of
developement of society.
Children and young with antisocial propensity: Theoretical models for identification and social importance of prevention of antisocial behaviour
Authors: Radulovic Danka , Ilic Zoran
Published: July 2018

Alarming increase of antisocial behaviour among children and young, eroding
social values and weakening of the educational role of family and school has
resulted in the fact that social integration of the younger generation
actually becomes their adaptation on antisocial and deviant environment. The
main precondition for overcoming such situation is early recognition of
antisocial propensity of children and young because only then, at early age
applying psychological and social educational interventions can be
effective. This article is founded on empirical findings in the area of
psychology of conduct disorders and analysis early manifestations of
antisocial propensity and gives us an overview of theoretical models
relevant for the early identification of the risk group of children and
young. It points to the importance of the social context and prevention of
antisocial behaviour including introducing institutional standards and
procedures to identify children at risk, as well as strict adherence to the
code of professional ethics.

Wheat grain samples from 108 fields in Slovakia were analysed for their technological quality parameters and deoxynivalenol (DON) content. A total of 206 samples were sorted into those that were suitable (S; n = 186) and those that were unsuitable for human consumption (U; n = 20). The S samples were sorted into grain quality grades (E – elite; A – standard; B – minimum; P – biscuit). The natural occurrences of DON were 72.3 % in the E; 84.9 % in the A; 86.1 % in the B; 58.1 % in the P and 100.0 % in the U samples. The mean DON content was 0.55 mg kg−1 in the E; 0.47 mg kg−1 in the A; 0.67 mg kg−1 in the B; 0.36 mg kg−1 in the P and 1.67 mg kg−1 in the U samples. The natural mean DON contamination of the human consumption samples was lower (0.52 mg kg−1) than for the samples that were unsuitable for human consumption (1.67 mg kg−1).

There is increasing global interest in using compost to suppress soil-borne fungal and bacterial diseases and nematodes. We studied the reproducibility of compost suppressive capacity (SC) against Pythium wilt of cucumber using nine composts produced by the same composting plant in 2008 and 2009. A bioassay was set up in a greenhouse using cucumber inoculated with two strains of Pythium. The composts were used as 20% mixtures (v:v) of a basic steam-sterilized light Sphagnum peat and sand (3:1, v:v). Shoot height was measured weekly during the 5-week experiment. At harvest, the SC was calculated as the % difference in shoot dry weight (DW) between non-inoculated and inoculated cucumbers. The SC was not affected by year of production (2008 or 2009), indicating reproducibility of SC when the raw materials and the composting method are not changed. Differences in shoot height were not as pronounced as those for shoot DW. The results were encouraging, but further studies are still needed for producing compost with guaranteed suppressiveness properties.
Potential and limitations of phosphate retention media in water protection: A process-based review of laboratory and field-scale tests

Published: July 2018

The application of phosphorus (P)-sorbing materials offers a possible solution for treating municipal wastewaterand agricultural runoff. In this paper we discuss P retention and release mechanisms, and review studies on the Pretention of different materials and their use as reactive media in filter beds. The main mechanisms for P retentionare sorption on metal (mostly Fe or Al) hydroxide surfaces and, in alkaline conditions, the formation of Ca-Pprecipitates. The retention of P is strongly affected by the chemical composition of a material, its particle size andpH-related effects on sorption and precipitation both during testing and in practical operation. Laboratory testsare sensitive to solution chemistry (pH, alkalinity, ionic strength and composition, P concentration) and affected bymaterial-to-solution ratio, contact time and agitation. Moreover, due to deviations from realistic field conditions,laboratory tests may produce imprecise estimates of the retention capacity and retention kinetics. In particular,materials that contain soluble substances (e.g., CaO) that elevate the pH of the ambient solution to high levels mayin batch tests suggest a high capacity for P retention, but will most probably show much lower retention in fieldsettings. On the other hand, materials containing metal oxides also retain P via slow reactions, and their retentioncapacity may be underestimated in short equilibrations. Appropriate laboratory test procedures will dependon their intended applications and material properties. Long-term field-scale tests are few in number, but some ofthem have shown promising results. Field-scale tests have, however, highlighted the design of the filters as a criticalfactor in their efficiency. ﻿
Characterisation of two unique unifloral honeys from the boreal coniferous zone: lingonberry and mire honeys
Authors: Salonen Anneli , Julkunen-Tiitto Riitta
Published: July 2018

Studies of unifloral honeys are rare in Finland, and thus there are no common traits accepted for their characterization. In our study lingonberry and mire were characterized. The physico-chemical, organoleptic and melissopalynological properties and phenolic composition of the honeys were analysed and the floral origin of the mire honey was considered. Lingonberry honey is reddish and has a flavour of toffee, whereas mire honey has very strong aroma and reddish colour. Both honeys have high electrical conductivity and pH when compared to Finnish polyfloral honeys. They are both rich in fructose, while the number of disaccharides in lingonberry honey is four and in mire honey six. Lingonberry honey has three unifloral specific phenolic compounds. Mire honey has no unifloral-specific phenolic compounds, and its floral origin is not clearly defined.

The aim of this study was to determine the effect of meat and bone meal (MBM) used as an organic fertilizer on maize grown for grain. A two-factorial field experiment in a randomized block design was carried out in 2010 and 2011, in north-eastern Poland. Experimental factor I was MBM dose (1.0, 1.5, 2.0 and 2.5 t ha-1 year-1), and experimental factor II was the year of the study (two consecutive years). Increasing MBM doses contributed to an increase in maize grain yield and 1000-grain weight. The yield-forming effect of MBM applied at 1.5 t ha-1 year-1 was comparable with that of nitrogen and phosphorus contained in mineral fertilizers. A dose of 2.5 t ha-1 MBM led to a significant increase in maize grain yield. The P and K content of maize grain was determined by MBM dose, whereas the concentrations of N, Mg and Ca in grain were not affected by MBM dose. Significantly higher N, P, K and Mg uptake by maize plants was observed in treatments with the highest MBM dose, compared with the control treatment. Nitrogen and phosphorus uptake per 1 t MBM reached 101 kg and 26 kg, respectively. The results of a two-year study show that the maximum MBM dose (2.5 t ha-1 year-1) met the fertilizer requirements of maize with respect to nitrogen and phosphorus.
Microbiota of an unpasteurised cellar-stored goat cheese from northern Sweden

Published: July 2018

This qualitative study reports on lactic acid bacteria (LAB), yeasts and moulds isolated from three artisanal Swedish cellar-stored goat cheeses aged for 1, 3 and 5 months. Starter culture LAB dominated in the younger cheeses, and Leuconostoc pseudomesenteroides, common in raw goats’ milk, had persisted from the unpasteurised milk into all the cheeses. Non-starter LAB dominated in the 5 month cheese, in particular, Lactobacillus sakei, a meat-associated LAB not previously isolated from cheese. Debaryomyces hansenii, and Penicillium and Mucor species were dominant among the yeasts and moulds, respectively. The cheese rind was not formed primarily from Penicillium species as in traditional cheeses such as Camembert – rather, mycelium from Mucor mucedo contributed to rind formation. Mould species known to produce sterigmatocystin, aflatoxins or ochratoxin A in cheese were not isolated in this study; growth of mycotoxigenic Aspergilli may have been inhibited by the cool conditions in the earth-cellar (4–6 °C).
