Authors: Rosser-Limiñana Ana , Jareño-Ruíz Diana , López-Sánchez Carmen
Published: June 2018

El azote o el cachete siguen siendo prácticas socialmente aceptadas como estrategias educativas con los menores. Sin embargo, su uso entraña riesgos en su ajuste psicosocial que podrían evitarse poniendo en marcha estrategias de disciplina positiva. Para sensibilizar a padres y madres contra el uso del castigo físico y dotarles de herramientas educativas alternativas es necesario desarrollar nuevos instrumentos de comunicación eficaz que llamen su atención, sean accesibles y ofrezcan contenidos en la línea propuesta. En este trabajo se presenta el proceso de implementación de una aplicación para dispositivos móviles (smarphones, tablets y phablets) orientada a la eliminación del castigo físico en la educación parental. La app tiene como objetivo ofrecer apoyo on-line a los padres y madres en su labor educativa, a partir del modelo de disciplina positiva. Para ello, se basa en la autoevaluación y el aprendizaje a través de entornos virtuales (e-parenting). Se concluye sobre la utilidad del enfoque educomunicativo para el desarrollo de este tipo de competencias y las características que deben cumplir para llegar al público objetivo, detectar posibles dificultades y mejorar las estrategias para potenciar la educación mediática parental en el proceso de crianza y educación.

PARA QUE SERVE E/OU A QUEM SERVE UMA CONSTITUIÇÃO? JUSFILOSOFIAS À LUZ DE SIEYÈS, LASSALLE, HESSE E HABERLE
Authors: Teles Tayson Ribeiro
Published: June 2018

No presente escrito, tem-se o escopo de tecer um plexo de reflexões sobre a função de uma Constituição, na perspectiva de pensar para que este gênero normativo deve existir, bem como a quem deve servir. A metodologia de feitura da pesquisa é a exploração bibliográfica revisional qualitativa e o caminho perquirido rumo ao alcance das reflexões lastreou-se na dedução, por meio da qual se parte de dados gerais e erigem-se ideias singulares. Para tal, faz-se uso dos pensamentos gerais de Sieyès, Lassalle, Hesse e Haberle, ideias tais presentes em suas mais importantes obras, e auferem-se reflexões particulares – a investigação em si. Os resultados demonstram, em escorço, que uma Constituição serve para fundar uma nação, garantindo direitos fundamentais a seu povo, e servir-lhe de baliza para a confecção de outras normas, além do que a Constituição deveria servir ao povo, a todos (hipótese), mas infelizmente serve em maior grau a poucos, notadamente os donos do capital/poder.
INTERPRETAÇÃO CONFORME A CONSTITUIÇÃO: UMA ANÁLISE DA ATUAL PERSPECTIVA DO SUPREMO TRIBUNAL FEDERAL A PARTIR DOS SEUS LIMITES DOUTRINÁRIOS E JURISPRUDENCIAIS
Authors: Teixeira Anderson Vichinkeski , Nedel Nathalie Kuczura
Published: June 2018

A interpretação conforme a Constituição tem como objetivo evitar a declaração de invalidade da norma, posto que o Poder Judiciário, em meio as várias interpretações possíveis, delimita aquela que se coaduna com a Constituição. Assim, a fim de não haver usurpação de competências, existem limites à aplicação do princípio em questão. Nesse contexto, bem como considerando que o Supremo Tribunal Federal é o guardião da Constituição, cabe perquirir em que medida referido órgão do Poder Judiciário vem observando corretamente o princípio em tela, mormente em relação à sua conceituação e às suas limitações. Para responder ao problema de pesquisa posto, utilizou-se como método de abordagem o dedutivo e como método de procedimento o monográfico. Ademais, como técnica de pesquisa empregou-se a bibliográfica e a jurisprudencial, limitando a análise desta à jurisprudência do Supremo Tribunal Federal no ano de 2016, mais especificamente aos acórdãos por ele proferidos que utilizaram do princípio da interpretação conforme. Ainda, o artigo dividiu-se em três itens. No primeiro, apontaram-se os principais elementos conceituais acerca da interpretação conforme. Já no segundo, foram detalhados os casos, utilizando o princípio em questão, que foram julgados pelo Supremo no ano de 2016. Por fim, no terceiro capítulo, determinou-se em que medida referidas decisões observaram de modo coerente os limites da interpretação conforme.

Narcolepsy With or Without Cataplexy In The Pediatric Population: A Systematic Review
Authors: Nazir Racha , Bennett David S , Sedky Karim
Published: June 2018

Study Objectives: Narcolepsy diagnosis has been associated with a long lag time between the onset of the disorder and the diagnosis itself among patients with the disorder. This article reviews the childhood epidemiology of idiopathic narcolepsy, including its prevalence, subtypes, and disease progression.

Methods: A literature review was conducted to include both published and unpublished data on pediatric narcolepsy. All English language articles were included through April, 2015.

Results: Time from symptom onset to diagnosis for children is approximately three years. The prevalence of cataplexy appears to be lower in children compared to adults, suggesting a later onset of cataplexy. The presence of cataplexy, however, was unrelated to demographic factors and laboratory findings.

Conclusion: There is a substantial lag-time between initial symptom presentation and diagnosis in children with narcolepsy. A less quintessential presentation of narcolepsy might occur in children relative to adults, making diagnosis more challenging. Continued improvements in narcolepsy education for both pediatricians and parents might facilitate earlier identification and diagnosis of the disease, thus leading to improved outcome.

Authors: Vaidya Praveenkumar , N. S. Harinarayana
Published: June 2018

Of late, social tagging has become popular trend in information organisation. In context of digital resources the tags assigned by users also play vital role in information retrieval. For information discovery the ‘terms’ used to retrieve the results also depend upon the ‘relevancy’ or ‘weightage’ of the keywords. This study investigates ‘relevancy ranking’ of terms used in the full text of the resource. The common words present in both full text of the article and social tags were considered for the study by employing TF-IDF statistical technique and Jaccard similarity test. The results show that it is possible to assign ‘weight’ to keywords for better results and also determine the significant tags assigned by the user. The Jaccard similarity coefficient test adopted to understand the word similarity between full text words of an article and marine social tags. This work reveals the social tags can enrich metadata for information retrieval.

Published: June 2018

The purpose of this research is to examine the perceived importance and perceived experiences of library service quality for hospitality management students. Also, an effort was made to identify the strengths and weaknesses of library service quality based on their perception of library services. The researchers have used LibQUAL+®, a popular tool that libraries use to assess the perception of library service quality over the years. Undergraduates and postgraduate’s students studying in one of the premier private hotel management institutes in India participated in this study. The findings of the study suggest that library service providers need to understand the needs of students and should have the inclination to help students in making the library a gateway for study, learning and research. The future research may include faculty members’ perception of importance and performance of library service quality. This type of survey can be repeated at regular intervals to distinguish the varying needs of library users.

Published: June 2018

The present paper investigates the distance students’ use of public libraries for their academic purposes and converse the public library as a alternate for instructive or University libraries. The current research study is based on a comprehensive survey of distance education students from Bangalore University. The data collection was carried out by personally distributing the questionnaire to the randomly selected students and the sample consists of students from both undergraduate and post graduate. It is found from the study that 1309 (90.60 %) distance learners who used public libraries during contact classes and 786 (54.4 %) of the respondents spent 0-1 h in the library. Majority of the distance learners i.e. 941 (65.10 %) responded effective for book borrowing services from the public libraries in seeking information, 1220 (84.40 %) opined effective for reference services. It is observed from the study that distance students have a tendency to look at libraries as a complete and do not make apparent difference between different types of libraries, expecting the entire system to be flawless. The paper lifts the significant executive inquiry and apprehension in relation to both the operation of public libraries and the service level given to diverse section of learning students. It is strongly recommended that library instruction programme should be organized by the public libraries for distance learners that create the responsiveness and use of library and information services effectively.

Published: June 2018

The phytochemical screening, antioxidant capacity, and total polyphenols in the methanolic extract of leaves, flower buds, roots and fruits of Capparis spinosa collected from trans-Himalayan region of Ladakh were assessed in an effort to corroborate its medicinal and culinary potential. Highest DPPH and ABTS radical scavenging activity were observed in the leaves and least in dried fruit samples, even FRAP assay also illustrated the same trend. IC50 values of DPPH assay was highly correlated with that of ABTS (R2=0.9084) and FRAP assay (R2=0.9771). However, IC50 value of ABTS was reasonably correlated with FRAP assay (R2=0.5838). The highest phenolic and flavonoid content was recorded in the leaf samples (24.78 and 5.69 mg GAE/g DW respectively), whereas it was lowest in the dried fruit samples (4.07 mg quercetin equivalent/g DW and nil, respectively). The total phenolic contents were highly correlated with IC50 value of ABTS (R2=0.9084), DPPH (R2=0.9388) and FRAP value (R2=0.9618). But, total flavonoid contents were highly correlated with ABTS (R2=0.7449), DPPH (R2=0.8791) and FRAP values (R2=0.9588). Thus, this study has validated the medicinal potential of all the edible parts of the C. spinosa.

Published: June 2018

Zanskar pony, a native horse breed of Ladakh mainly used for transportation in Trans-Himalayan region of India, is well adapted to high altitude hypobaric hypoxia environment. Due to extreme conditions of the Ladakh region, better endurance of these ponies under hypoxic and extreme cold conditions is of utmost concern for their recruitment in Indian Army. In the present study, 12 young trained Zanskar ponies were evaluated during endurance exercise at an altitude of 3292 meter above mean sea level. The animals were subjected to carriage transport with 65-70Kg load or riding on a track of 5-6 Km. Physiological parameters viz., pulse rate (PR), heart rate (HR), rectal temperature (RT), respiratory rate (RR) and oxygen saturation (SaO2) were recorded in Zanskar ponies during pre-exercise (T0), post- exercise (T1) and post recovery (T2, 2 hours post resting) stages. Results showed marked increase in PR, HR, RR and RT post exercise time points. The mean values of PR increased from 49.83±4.62 to 73.67±21.54 per minute, HR from 48±13.60 to 75±15.82 beats/min, RR from 37.83±9.70 to 57.67±13.48 per min and RT from 99.62±0.34 101.04±0.53 °F from pre stress to post endurance stress. The mean SaO2 level reduced significantly (88.58±6.75 at T0 versus 64.00±18.70 at T1 and 54.42±14.79 at T2) post exercise. This indicated limited availability of arterial oxygen for tissues which could be vital factor for adverse change in some of physio-biochemical parameters. Though the trend of physiological response was similar for all the 12 animals, still variation at individual animal level was observed during endurance stress. In future, some of these physiological parameters along with biochemical and molecular parameters could be evaluated as potential biomarkers in selecting ponies with superior endurance trait specifically under hypoxic conditions.

Glucosinolates (GS) are amino acid derived secondary metabolites present specifically in Brassicaceae family. The effect of altitude (2800 m - 4000 m) on GS contents and seed quality characteristics in radish (Raphanus sativus L.) was investigated. The total GS in radish seed was 147.5±21.5 μmol/g DW, which included five aliphatic and four indolic GS compounds. Increasing altitude was related linearly to increase in total GS contents (R2 = 0.759). Among individual GS, glucoraphanin and glucoraphenin showed consistently increasing trend with altitude. Increasing altitude is related linearly to increase in 100 seed weight (R2 = 0.266) and seed yield per plant (R2 = 0.849). A steady decreasing trend was observed in seed moisture content (R2 = 0.831) and siliqua length (R2 = 786) with increasing altitude. Altitude of plant origin was positively correlated with GS contents (r = 0.900, p≤ 0.01), seed weight per plant (r = 0.919, p≤ 0.01) and geometric mean diameter (r = 0.661, p≤ 0.01), and negatively correlated with siliqua length (r = -0.880, p≤ 0.01), moisture content (r = -0.884, p≤ 0.01) and seed vigour index (r = -0.547, p≤ 0.01). Our results indicate that the concentration of GS in radish seed and seed quality traits can be significantly increased by growing plants at higher altitude.

Published: June 2018

Feasibility of growing muskmelon (Cucumis melo L.), a warm season crop, was studied under a low-input cultivation system in open field condition in high altitude (elevation 3344 m) trans-Himalayan Ladakh region. The marketable yield of five cultivars in different treatments varied from 5.4±0.4 t.ha-1 to 18.8±1.7 t.ha-1 and 4.0±0.2 t.ha-1 to 15.8±1.0 t.ha-1 in 2014 and 2015, respectively. Treatment of black polyethylene mulch (BPM) increased marketable yield by 25 per cent to 155 per cent depending on year and cultivar. The marketable yield of the best performing cultivar (Pusa Madhuras) under BPM was 17.3 t.ha-1, which suggested that muskmelon can successfully be grown in open field condition in trans-Himalaya. The fruit become ready for harvest in mid-August. Number of fruit per plant ranged from 2.3 to 6.3, and TSS ranged from 8.9 to 14.1 °Brix depending on cultivar. Temperature 10 cm beneath the BPM was 2.9±0.4 ºC higher than in bare soil. BPM reduced 74 per cent weed and save 77 per cent time in manual weeding.
A Field Study on Concurrent Spare Parts Recommendation in an Airborne Weapon System
Authors: Noh Giseop , Oh Hayoung
Published: June 2018

As the complexity of weapon systems has grown exponentially during the past few years, initial operation capability has been a crucial factor for military forces. Concurrent spare parts (CSPs) is the quantity of spare parts ensuring initial operating period specified by demanding forces acquiring newly deployed weapon systems. Because of the growth of system complexity, recommending precise CSP is not trivial. The Republic of Korea developed an improved CSP recommendation system and deployed the system for naval weapon systems. In this paper, we increase the prediction accuracy of CSP up to 23.1 per cent and 7.16 per cent higher in terms of budget constraint and operational availability (Ao) constraint. The main improvement is achieved by facilitating simulations using the real field data from Korean air force. Also, we propose two validation approaches and show the possibility of extension to the general weapon systems. From the experimental study, we show that the CSP recommendation system can be deployed for navy and air forces.
Bandwidth Enhancement of Substrate Integrated Waveguide Cavity-backed Bow-tie-complementary-ring-slot Antenna using a Shorted-via
Authors: Kumar Arvind , Raghavan S.
Published: June 2018

In this study, a planar cavity-backed bow-tie-complementary-ring-slot antenna is proposed, and a new approach for bandwidth enhancement using a shorted-via is introduced. A shorted-via concept overcomes the narrow impedance bandwidth of a conventional substrate integrated waveguide cavity-backed antenna. By adjusting the location of the shorted-via (placed just above the centroid of the radiating slot), the individual bandwidth of the lower and higher order resonances has been tuned below -10 dB criterion, which results in the broadening of the bandwidth. Finally, the antenna is proficient to operate for an impedance bandwidth of 15.71 per cent, ranging from 12.02~14.07 GHz. The proposed antenna shows a gain of better than 4 dBi within the operating band with less than 0.5 dBi variation. Moreover, the antenna preserves good radiation characteristics, which is similar to that of the conventional metallic counterpart. To validate the simulated results, an antenna is fabricated and tested. The simulated results in terms of the reflection coefficient, gain, and radiation patterns are in good agreement with the measured results.
Ricochet of Spheres on Sand of Various Temperature
Authors: Kim Yoon Keon , Choi Woo Chun
Published: June 2018

The debris generated by the explosion of a building or ammunition is flown far away through the ricochet phenomenon. The debris contains a very large amount of energy, and a risk factor surrounding it may be applied. The safety distance from debris is set from experiments or FEM analysis. The ricochet of debris is affected not only by the initial conditions of the debris, but also by the conditions of the medium. In this paper, the effect of sand temperature on the ricochet of sphere projectiles was investigated through experiments and FEM, by measuring the shear stress and internal friction angle when the sand temperature increases. As the temperature of the sand increases, the shear stress and the internal friction angle decrease, and the penetration depth of the projectile increases. As the depth of penetration becomes longer, the kinetic energy is lost more by the friction force with the sand and, the sphere projectile speed decreases more. This is mainly caused by the energy loss of the projectile, so the kinetic energy of the ricocheted projectile is reduced. Therefore, when setting the optimized inhabited building distance (IBD), the conditions of the medium should be taken into account.

Published: June 2018

The design and fabrication of gate/source connected multi-finger field plate structures using TCAD ATLAS simulation software is presented. The designed field plate structures are fabricated on indigenous AlGaN/GaN HEMT devices. AlGaN/GaN HEMT devices with field plate structures exhibit about three times improvement in breakdown voltage of device and are in close agreement with the simulation results. Integration of field plates in device have resulted in higher VDS (drain to source voltage) operation and improvement in output power of AlGaN/GaN HEMT devices. Incorporation of field plates also decrease the reverse leakage current of HEMT devices.
Implementation of Peltier Cooling in Hermetically Sealed Electronic Packaging Unit for Sub-sea Vessel
Authors: S. Madhavan Nampoothiri , M. Sabu Sebastian , P.C. Sajith Kumar
Published: June 2018

This paper presents the methodology adopted for implementation of Peltier cooling in hermetically sealed electronic packaging units used in sub-sea vessels. In sub-sea vessels, sonar front-end electronics is packaged in hermetically sealed electronic packaging units. The thermal design of the unit is a highly challenging task considering the heat dissipation of 300W from the electronics, non-availability of chilled air for cooling and IP68 sealing requirements. Cooling fans cannot be integrated, since these units are to be placed in acoustically sensitive pressure capsule area of the subsea vessel. The electronic cooling in this unit is achieved using conduction cooling with external fins. To enhance the cooling, suitable Peltier cooling (Thermo-electric cooling or TEC) module is selected and implemented with the system. Computational fluid dynamic analysis of the unit is carried-out to study the air-flow and thermal performances with Peltier cooler. The unit is realised and the estimated temperatures validated by experimental temperature measurements on the realised unit. The measured temperatures are within the safe operating limits of the electronic components and hence the cooling design of the unit is satisfactory. It is also observed that maximum temperature reduction has occurred at 1.5A current and card edge temperature of Printed circuit board lowered by 9.28 °C by implementing Peltier cooling.
Robust Stabilised Visual Tracker for Vehicle Tracking
Authors: Verma Kamlesh , Kumar Avnish , Ghosh Debashis
Published: June 2018

Visual tracking is performed in a stabilised video. If the input video to the tracker algorithm is itself destabilised, incorrect motion vectors will cause a serious drift in tracking. Therefore video stabilisation is must before tracking. A novel algorithm is developed which simultaneously takes care of video stabilisation and target tracking. Target templates in just previous frame are stored in positive and negative repositories followed by Affine mapping. Then optimised affine parameters are used to stabilise the video. Target of interest in the next frame is approximated using linear combinations of previous target templates. Proposed modified L1 minimisation method is used to solve sparse representation of target in the target template subspace. Occlusion problem is minimised using the inherent energy of coefficients. Accurate tracking results have been obtained in destabilised videos.

Published: June 2018

In many engineering domains, cognition is emerging to play vital role. Cognition will play crucial role in radar engineering as well for the development of next generation radars. In this paper, a cognitive architecture for radars is introduced, based on hybrid cognitive architectures. The paper proposes deep learning applications for integrated target classification based on high-resolution radar range profile measurements and target revisit time calculation as case studies. The proposed architecture is based on the artificial cognitive systems concepts and provides a basis for addressing cognition in radars, which is inadequately explored for radar systems. Initial experimental studies on the applicability of deep learning techniques under this approach provided promising results.

Authors: Dursun Tolga , Utlu Çağrıhan , Özkan Enis Naci
Published: June 2018

Fire power for a main battle tank is one of the most important performance parameters like survivability and mobility. Fire power effectiveness is directly related to the first shot hit probability, performance of main gun, second armament, gun and turret drive system, fire control system, automatic target tracker, commander and gunner sight etc. First shot hit probability (a measure of cumulative effects of errors) is affected by the variations of the projectile parameters, the main gun structure uncertainties, fire control system errors, interaction between the projectile and the gun barrel and the unpredictable environmental changes. These errors and variations can be eliminated or minimised by understanding and simulating the firing event properly, manufacturing the related parts in high precision, using advanced fire control algorithms, and accurate sensors. In this review study, the effects of main gun structural components on the first shot hit probability are investigated taking into account all of the associated error sources. In order for a main battle tank to have both high and repetitive first shot hit probability under all battlefield conditions the gun structure should respond in a similar manner in successive firings without causing any abrupt change in performance. In this study, first the dynamic behaviour of gun/projectile system is discussed and then the design recommendations for the main gun components such as bearings, gun barrel, recoil system etc. to achieve higher first shot hit probability are reviewed.

Infection of Onion yellow dwarf virus (OYDV) are reported causing problems in garlic production. Planting virus-free bulbs might help reduce viral disease incidence in the field. This research was aimed to develop method for eliminating OYDV from garlic bulbs using combination of electrotherapy (0, 5, 10, 15, and 20 mA each for 10 minutes) and thermotherapy (23, 28, 33, 38°C each for 4 weeks). Two garlic cultivars, i.e. Sangga Sembalun and Lumbu Hijau were used as seed bulbs for OYDV elimination tests. Virus infection was confirmed using transcription-polymerase chain reaction (RT-PCR).  The result showed that thermotherapy at 33 °Cwas the best method to eliminate OYDV in garlic although the efficiency was not the same for all cultivars. The efficiency reached up to 60% for cv. Lumbu Hijau, whereas for cv. Sangga Sembalun only reached up to 40%. Electrotherapy alone or in combination with thermotherapy were not able to produce OYDV-free plantlets.
Polskie i europejskie standardy wykonywania wolnych zawodów

For some time Poland has been debating the issue of the existence and functioning of professional corporations. This debate concerns only those professions that are deemed professions of public trust and which have been granted the privilege of developing their respective professional self-governing bodies. European solutions for regulating the issue of such professions are varied and have attracted the attention of the European Union. Contemplating the evolution of the Polish political system in the field of self-governing bodies it is worth paying attention to the European standards regulating the functioning of free professions, which include what are considered professions of public trust in Poland. The said regulations set certain standards for the Polish regulator to be followed and implemented.
Spór o multipleks. Telewizja Trwam kontra Krajowa Rada Radiofonii i Telewizji
Authors: Secler Bartłomiej
Published: June 2018

The digitalization of terrestrial television in Poland is one of the largest media projects in recent years. The process combines social, economic and technical matters. Digitalization signifies a huge technical leap forward and offers extensive new opportunities when broadcasting television signals. Digital broadcasting is offered by three multiplex platforms. Among the candidates to use the first one (MUC-1) is Telewizja Trwam, owned by the Lux Veritatis foundation. The National Broadcasting Council (KRRiT) which assigns the concessions to use the multiplex rejected the application by Telewizja Trwam, associated with Fr. Tadeusz Rydzyk. The owner of Telewizja Trwam claimed the decisions of the KRRiT were baseless. There quickly emerged accusations of discrimination against a Catholic broadcaster, and, by this token, of scorn directed toward Polish Catholics. The dispute between Telewizja Trwam and the KRRiT has involved many groups and individuals – ranging from the supporters of the media associated with Fr T. Rydzyk, to journalists, politicians, and to the hierarchy of the Catholic Church in Poland. The purpose of this paper is to present this dispute, its background and the arguments of both parties. As the dispute was still unresolved when this paper was completed (in late February 2013), the author tried to suggest possible scenarios for its outcome and to draw conclusions for the future.
Prasa lokalna w leszczyńskim regionie wydawniczym. Przyczynek do badań nad zawartością treści w kontekście sportowych wydarzeń medialnych, ze szczególnym udziałem kobiet

The analysis of the content of Wielkopolska periodicals in the period from 1989 to 2011 indicates that female issues comprised two currents. One presented the historical and modern image of women, while the other discussed female issues in the context of political, economic and social events. In the first decade following the transformation the regional and local press confirmed the presence of the stereotype of female roles, but studies carried out in 2011 indicated that male and female roles were unified in numerous aspects of everyday life. This paper aims to deepen the issue previously discussed by the author, but only in the context of the qualitative changes that have occurred in the presentation of sports releases, focusing on sports events involving women in particular. To this end Wielkopolska local and regional newspapers, and local newspapers from the Leszno region (south-western part of Wielkopolska, the northern part of Lower Silesia and the south-eastern part of Lubuskie) in 1989–2012 were analyzed.
Problematyka władzy międzynarodowej
Authors: Maj Czesław
Published: June 2018

One of the fundamental categories of general sociology concerns power. Regardless of differences in interpretation, power can be defined as the dependence between subordinator and subordinated. This relation is unidirectional. When discussing influence, this property is significant, as otherwise it could be reciprocal, or an influence could be exerted by many other entities that are not bound by the relationship of subordination. The nature of international relations is too specific to allow a simple transfer of power-related phenomena from the realm of domestic relations. One can indicate the presence of delegated power, resulting from the mutual assignment of subordination rights to international decision- making bodies. The processes of international power are divided into procedures of hard power, soft power and smart power, the latter signifying the manifestation of effective power, making use of the mechanisms of the former two. It is also important to take into account the specificity of the legitimization of international power and manifestations of accountability. Also not without significance is the capacity for the implementation of international power, equipped with the relevant enforcement instruments.
Władza ludu czy elit politycznych? Próba zdefiniowania współczesnej demokracji
Authors: Rachwał Marcin
Published: June 2018

Taking into consideration the etymology of the concept, it seems obvious that democracy stands for the power of the people. It needs to be borne in mind, however, that the concept of democracy was coined in Antiquity and served to describe the political reality at the time. The premises and practice of modern democratic states have considerably diverted from the ancient model. It therefore seems justifiable to ask whether democracy continues to stand for the power of the people. From the point of view of Ch. W. Mills, for instance, the power of the people is an idealistic intention and a noble postulate rather than a realistically achievable political phenomenon. He is not alone in this opinion. Therefore, the question arises of how to define modern democracy. Bearing in mind the considerable variety of current democratic states, it can be assumed that modern democracy is a system where the authorities are publicly accountable to the citizens, who act by means of elected representatives that compete and cooperate with one another. In other words, democracy is the power of a political elite controlled by the people via cyclical, competitive elections. Direct democracy needs to be highlighted here, as it is considerably closer to the etymology of the word ‘democracy’ and its Greek roots. Apart from Switzerland, however, the instruments of direct democracy are tools construed not for the citizens but rather for an opposition that can use them in order to build their position. In this manner the institutions that, by definition, should belong to the citizens have become instruments used by the political elite.
Kultura bezpieczeństwa w imprezach masowych w Wielkopolsce. Analiza działań Miejsko-Wojewódzkiego Sztabu Operacyjnego Euro 2012 w Poznaniu
Authors: Magiera Maciej
Published: June 2018

The narrow sense of security, reduced to the ability to survive, has nowadays become insufficient in terms of what society demands. As a result of globalization processes (and the dynamization of reality), the will to maintain a high standard of living (consumerism) and the increasing awareness of individuals in Western culture, the need for a comprehensive minimization of risk has emerged, and hence a demand to look for potential threats in practically every field of life, in order to identify and eradicate them. By means of referring to the culture of security, or – to be more precise – to its three components (resources, organization and mentality), the social expectations of the public administration can be identified. This paper reflects the expectations of the citizens of Wielkopolska as regards the security of mass events on the basis of the operations of the Urban-Regional Headquarters of Euro 2012 in Poznań (and the standards and factors influencing its decision-making status).
Przesłanki rozwiązania parlamentu w praktyce ustrojowej V Republiki Francuskiej
Authors: Jakubiak Łukasz
Published: June 2018

The paper discusses the grounds required for the dissolution of the parliament in the political practice of the French Fifth Republic. The Constitution of October 4, 1958 adopted a model of strengthened political power of the head of state, granting them instruments of executive influence on the functioning of other state organs. Paragraph 12 of the Constitution gives the President practically unlimited power to dissolve the National Assembly – the lower chamber of French parliament. The conditions for applying this paragraph are not stipulated in the legal regulations. It is not necessary for the President to respond to a motion of another body, or even to obtain a countersignature. These constitutional factors have led to various political practices. The author of the paper puts forward the thesis that giving freedom to the head of state as regards the application of paragraph 12 on the one hand provides the necessary foundations to exercise a power model with a considerable degree of decisiveness, but on the other may lead to a situation where the dissolution of the National Assembly no longer has a power function in its conventional sense, but serves the purpose of providing the head of state with an instrument for considerably strengthening his own political position. Since the present Constitution of the Fifth Republic has been in force, the National Assembly has been dissolved five times. The author identifies three basic grounds for applying paragraph 12: to defuse a political or social conflict (1962 and 1968), to restore a politically homogenous executive power (1981 and 1988), and to maintain a given political configuration (1997). Since the 1980s the dissolution of parliament has become a tool for the president to avoid cohabitation and, by this token, to provide a political system where the role of the leader of the executive is in the hands of the head of state. On account of the defeat of the formation supporting the president in 1997 this strategy failed to produce the expected outcome. The dissolution of the National Assembly has not taken place since. In 2000, the length of the mandate of the head of state was shortened to five years, which makes it more likely for parliamentary elections to occur directly after presidential elections. This may for a long time to come eliminate the main grounds for the dissolution of the lower chamber, which in the 1980s and 1990s stemmed from the desire to ensure a political system favorable for the head of state. This reason alone may mean that the significance of paragraph 12 in the political practice of the Fifth Republic will continue to be limited.
Some Aspects of Political Public relations Strategy based on the Example of Polish extra-Parliamentary Left-Wing Parties. The First Decade of the 21st Century

Badanie strategii politycznego public relations partii politycznych w zakresie budowania wizerunku jest ciekawym i ważnym tematem. Celem artykułu są rozważania na temat miejsca i roli partii pozaparlamentarnych, które kształtują polską lewicową scenę pozaparlamentarną. Ugrupowania te są do siebie podobne w kwestii budowanej struktury organizacyjnej, zapisu programowego (często łudząco przypominającego partie mainstreamowe lub statuty innych peryferyjnych ugrupowań lewicowych), sytuacji ekonomicznej (brak zaplecza budżetowego, co stanowi znaczną przeszkodę w finansowaniu kampanii wyborczych oraz utrzymywaniu poprawnych struktur partyjnych).
