Technological aspects of the mechanism of formation of local budgets in Ukraine for 2018-2020 years
Authors: Gordiienko Larysa , Zilinska Alina
Published: April 2019

The article deals with the technological aspects of the mechanism of formation of local budgets in Ukraine, which is an important tool for state policy, the development of administrative and territorial units, and ensuring an adequate level of living standards. On the basis of the analysis carried out by the authors, it was revealed that the mechanism of formation of local budgets does not correspond to the current trends, therefore the components of legislative and regulatory support are systematized and the potential of their use for the changes of the existing mechanism is revealed. The technological aspects of the formation of local budgets are considered, namely, the composition of local budgets is determined, and at the expense of which the local budget is formed by the legislative base. The features of the mechanism of formation of local budgets and the main organizational and technological procedures for its development are determined. The authors highlighted the main shortcomings of the existing mechanism for the formation of local budgets, namely, the absence of a procedure for forming the income and expenditure part of local budgets. It is determined that local budgets of Ukraine are more dependent on intergovernmental transfers than local budgets of EU countries, the volume of transfers and their share in the organization of local budget revenues is constantly increasing. In this work, the authors proposed measures to eliminate the problems of the formation of local budgets.

Environmental Reporting in Pakistan’s Oil and Gas Industry
Authors: Khan Muzammal , Hassan Abeer
Published: April 2019

This paper investigates to what extent Oil and Gas (O&G) companies in Pakistan report on environmental protection activities. Using a content analysis approach, environmental reporting (ER) in 13 companies’ annual reports and websites are investigated over a five year period (2010-2014) following the guidelines issued by Securities Exchange Commission of Pakistan (SECP). Results reveal that the majority of the companies were found to have a low level of ER. However, since the introduction of SECP’s voluntary guidelines, the level of ER increased during the sample study period. Companies that issued a stand-alone report were found to have higher levels of disclosure on their environmental protection practices. This study recommends that management engage with internal and external stakeholders with their environmental management practices. The results may also be beneficial to the government as they provide reporting guidance and stock exchange regulations regarding the obligatory dissemination of environment-related information.

Efficiency of flood protection measures: selected examples
Authors: Kron Wolfgang , Müller Olaf
Published: April 2019

The frequency of flood loss events is increasing, both regionally and globally, due to the rising population and subsequent development of flood-prone areas, and as a result of environmental and climatic changes. This observation is not universally true for the time series of the losses themselves, at least not in the past one or two decades. One explanation for this is the improvement in flood control and flood protection in certain countries, both for floods that originate in the sea (storm surges) and for inland floods. While the qualitative effect of protection measures – reducing losses – is undisputed, quantitative examples are rare. Performance, or efficiency, needs to be calculated by comparing the costs of investment and maintenance against the losses prevented after a measure was put in place. In this article, a quantitative analysis of the performance of flood control measures is presented for four cases: the storm surge protection of the city of Hamburg, the Mississippi River and Tributary project, the activities of the Tennessee Valley Authority and the Sylvenstein Reservoir in Bavaria. In each case, a significant benefit has been observed in the past decades, proving that flood protection pays off many times over.

Trends in Turnover Research on Korean Nurses: Based on 8 Journals Published by Member Societies under the Korean Academy of Nursing Science, 2006-2015
Authors: Geun Hyo Geun
Published: April 2019

Purpose:

This study was done to identify the current status of turnover research on Korean nurses and to suggest directions for future research.

Methods:

A total of 63 articles over the past 10 years were selected using key words such as turnover intention or turnover-related variables from several databases. Frequency and percent were used to describe the characteristics of the turnover studies.

Results:

Quantitative research accounted for 90.5% of the total studies, and 60.3% of the studies were published by the Journal of Korean Academy of Nursing Administration. Most studies focused on the turnover intention of general nurses (71.9%) working in general hospitals (54.4%). Lawler’s turnover intention tool was used in 28.1% of the studies with a relatively high score for Cronbach’s alpha (0.7≤ a in 98.2% studies). 50.9% of the studies used descriptive survey design, and stepwise or hierarchical regression was used for the final statistical methods in 49.1% of the studies. Among the studies, 42.1% included job satisfaction as an influencing factor for turnover intention. In late twenties, single status, college graduates, staff nurse, low salary, and nursing experience with 1-5 years appeared to be significantly related to turnover intention across the studies.

Conclusion:

To date, turnover intention has been substituted for turnover in most studies. Because it is believed that nursing turnover will continue and ultimately challenge patient care and nursing outcomes, longitudinal research with actual turnover data is needed to produce new evidence on the turnover culture and its effects on health care outcomes in Korea.
Genetic Research: The Role of Citizens, Public Health and International Stakeholders
Authors: Fedeli Piergiorgio , Casella Claudia , Buccelli Claudio , Cannovo Nunzia , Graziano Vincenzo
Published: April 2019

Background:

Genetic research has become an indispensable instrument for medical research, and the subjects involved have both divergent and convergent interests.

Objective:

The possibility of having more detailed genetic information undoubtedly offers benefits for the health of the subject, but could also pose risks and make the subject vulnerable to discrimination.

Methods:

The scientific community has viewed very favorably the public health utility of family history, in which data from a family whose members suffer from chronic pathologies is collected and filed, in order to develop a sort of “stratification of family risk.”

Even though in the last decade the scientific and juridical literature has contributed greatly to the topic of biobanks, the perplexities that continue to surround this theme give the idea that current ethical protocols on research are inadequate.

Results:

Researchers, citizens, International stakeholders, mass media, Public Health and Governments play a key role in genetic research. It is obvious that the methods used for genetic research do not present intrinsic risks; they are much less dangerous than other activities of diagnosis and research. Before authorizing a research project, it is important to reflect on the responsibility and transparency of the studies to be conducted, and on the impact they may have on the interests of public health.

Conclusion:

We believe that the highest priority need is to develop a common language on the theme, as is the case in the sphere of clinical experimentation where rules of good clinical practice, albeit at times conflicting, have led to uniform convergences in the scientific world on the points to be actuated.
Pressure Ulcers Prevalence and Potential Risk Factors Among Intensive Care Unit Patients in Governmental Hospitals in Palestine: A Cross-sectional Study
Authors: Qaddumi Jamal A.S. , Almahmoud Omar
Published: April 2019

Aim:

To determine the prevalence rate and the potential risk factors of pressure ulcers (PUs) among patients in the intensive care unit (ICU) departments of the government hospitals in Palestine.

Methods:

A quantitative, cross-sectional, descriptive analytical study was carried out in five government hospital intensive care units in four different Palestinian cities between September 27, 2017, and October 27, 2017. The data of 109 out of 115 (94.78%) inpatients were analyzed. The Minimum Data Set (MDS) recommended by the European Pressure Ulcer Advisory Panel (EPUAP) was used to collect inpatients’ information.

Results:

The result of the analysis showed that the prevalence of pressure ulcers in the ICU departments was 33%, and the prevalence of PUs when excluding stage one was 7.3%. The common stage for pressure ulcers was stage one. It was also determined that the most common risk factors for the development of pressure ulcers were the number of days in the hospital, moisture, and friction.

Conclusion:

According to the recent studies in the Asian States, the prevalence of pressure ulcers in Palestine is considerably higher than in China and Jordan. However, it is still lower than the prevalence reported in comparable published studies in Western Europe. Increasing the staff’s knowledge about PUs screening and preventive measures is highly recommended in order to decrease the burden of PUs.

Authors: Latiefah Umi
Published: April 2019

Tulisan ini menjelaskan bagaimana waria memandang dirinya melalui masyarakat dan bagaimana pula sebaliknya masyarakat memandang identitas waria.Pada realitanya waria masih mendapatkan perlakuan diskriminatif karena identitasnya dipandang sebagai suatu penyimpangan. Pandangan ini berakibat pada penempatan waria sebagai kaum subaltern atau termarjinalkan, akan tetapi masyarakat sudah mulai terbuka dan menerima waria karena dilihat dari individunya bukan dari identitasnya, namun masyarakat sebagian besar belum bisa menerima identitasnya sebagai waria. Waria melakukan berbagai cara agar bisa diterima masyarakat salah satunya melalui pesantren. Pesantren sebagai alat untuk merekonstruksi identitas waria yang memberikan gambaran tentang image waria yang positif. Keberadaan pesantren khusus waria berhasil merekonstruksi identitas waria dengan menciptakan konstruksi baru yang mampu memberikan gambaran kepada masyarakat bahwa waria memiliki sisi positif dan masyarakat menyakini adanya perbedaan tingkah laku antara waria yang di pesantren dengan waria yang tidak ikut pesantren.Kata Kunci: waria, pesantren, identitas, subaltern.

Complejo volcánico Ñadó, norte del graben de Acambay: evidencias de magmatismo oligocénico y su relación con el sector central del Cinturón Volcánico Transmexicano
Authors: Cabrera-Román Jesús , Castro-Segura Javier , Valdez-Moreno Gabriel , Arce-Saldaña José Luis
Published: April 2019

El complejo volcánico Ñadó (CVÑ) se localiza en el sector central del Cinturón Volcánico Transmexicano (CVTM) y al norte del graben de Acambay, en los estados de Querétaro y México. Este complejo se compone de 11 unidades litológicas, las cuales se agruparon en tres secuencias (1. pre-Ñadó, 2. Ñadó y 3. post-Ñadó). La unidad más antigua es la Riolita La Florida (etapa 1. pre-Ñadó), fechada por el método U-Pb en circones en 30.81 ± 0.17 Ma y 31.71 ± 0.27 Ma, la cual puede ser atribuida a los pulsos de magmatismo félsico de la Sierra Madre Occidental (SMO) emplazados durante el Oligoceno. El resto de las secuencias se puede correlacionar temporalmente con los episodios de vulcanismo del Mioceno tardío en el CVTM, propuestos en trabajos previos. El estratovolcán Ñadó (etapa 2. Ñadó) se edificó a finales del Mioceno y se caracterizó por múltiples eventos efusivos, de composición dacítica, constituidos por varios derrames lávicos viscosos y emplazamiento de una espina (Peña Ñadó) y un domo (Cerro Pelón). Contemporáneamente se registraron eventos de vulcanismo máfico que formaron conos de escoria y emplazamiento de derrames basálticos. La etapa post-Ñadó consiste en una serie de lavas andesíticas e ignimbritas provenientes de las calderas de Amealco y Huichapan, vulcanismo máfico y depósitos de lahares. Adicionalmente, se reportan depósitos de caída asociados al volcán Temascalcingo. Geoquímicamente, las rocas muestran rasgos típicos de una zona de subducción de arco magmático continental, como enriquecimiento en los elementos litófilos de ion grande (LILE) con respecto a los elementos de alto potencial iónico (HFSE), anomalías negativas de Nb, Ta, P y Ti, así como, anomalías positivas en Ba, K, Pb y Sr. Los elementos de las tierras raras (REE) presentan un enriquecimiento de REE ligeras con respecto a las pesadas, mientras que la Riolita La Florida presenta patrones de REE con la típica forma de “gaviota” y una anomalía negativa muy marcada en Eu, lo que sugiere una génesis diferente al resto de las rocas. Las variaciones geoquímicas del volcán Ñadó pueden ser explicadas por el proceso petrológico de AFC.

Destruction of herbicide atrazine by solar radiation in photo-Fenton system
Authors: Zagibalova Christina Mikhailovna , Matafonova Galina Georgievna , Batoev Valery Babudorzhievich
Published: April 2019

The efficiency of solar-induced destruction of herbicide atrazine in natural water and aqueous extract from agrogenic and unbroken soil by using photo-Fenton system was studied in this work. 80-90 % atrazine was removed in all water matrices. Using xenon lamp as a solar simulator, the rate of atrazine destruction was found to be higher in aqueous soil extracts than that observed in natural water. However, no significant difference was found between the destruction dynamics in natural water and soil extracts, exposed to natural solar light. This could be attributed to the higher hydroxyl radical exposure under the higher UV irradiance of the Sun.

This issue includes papers that embrace major challenges for the board of directors A long line of research documents the crucial role that the board of directors plays in the reduction of agency costs. This issue of the journal goes further to explore a variety of environments, ranging from a highly developed economy, i.e., the United States, to a less developed economy, i.e., Greece and even developing ones, i.e., Saudi Arabian and Ghana. The results documented by the papers from this issue reflect the specificities of the environment in which companies are operating. Moreover, the channels through which the board of directors affects agency costs remain very little documented. Papers that are published in this issue shed new light on this topic by showing that boards might improve firm performance by enhancing corporate governance quality and developing informal communication within the firm.

Authors: Datt Ravi , Bhist Mangal , Kothiyal Alok , Maithani Rajesh , Kumar Anil
Published: April 2019

Experimental examination is carried out to study the turbulent heat transfer and fluid-flow characteristics in circular heat exchanger tube using combined wing with solid ring twisted tape inserts. A series of experiments has been performed with the range of Reynolds number varied from 3000 to 21000, number of twisted taped inserts, NTT, varied from 1.0 to 4.0 with constant value of other twisted tape parameters such as rings pitch ratio, dR /DT = 1.0, wing pitch ratio, PW /WT = = 3.0, and wing depth ratio, Wd /WT = 1.67. Based on the examined, turbulent heat transfer and fluid-flow in wing with combined solid ring twisted tape inserts results are compared with plain circular tube under same operating conditions. The experimental results show that the heat transfer is increased around 5.66 times than plane circular heat exchanger tube. The thermal and hydrodynamic performance parameter based on equal pumping power, ?p, was found to be highest for NTT = 3.0. The optimum value of thermal and hydrodynamic performance has been found to be 2.74 for Reynolds mumber of 3000 within the range of the parameters investigated. Multiple wings with solid rings twisted tape inserts have been also shown to be thermally as well as hydraulically better in comparison to other similar twisted tape insert geometries.

Authors: Jamil Abdullah , Baharom Bin , Lemma Alemu , Rao Tadimalla
Published: April 2019

Ball bearings are widely used in many machineries and industrial applications. Thermal behaviour of oscillating ball bearings is unknown due to its complex pendulum-like motion and is discussed in this research. In this research, the effect of operating conditions of the oscillating bearing performing coupler-rocker motion on the heat generation is experimentally investigated and verified using mathematical model. For this purpose, a coupler-rocker bearing testing rig was designed and fabricated and the test bearing is splash-lubricated in an oil sump. The loading of test bearing was done using two extension springs. The applied load on the bearing was varied from 0 to 750 N while the crank rpm was varied from 1200 rpm to 1800 rpm. Three lubricant grades were used namely, SAE30, SAE40, and SAE50. Experimental results showed that the temperature of coupler-rocker bearing approaches steady-state at about 12 minutes for all cases. The steady-state temperatures at variable conditions are observed to follow a linear trend.
Yenilenebilir Enerji Kaynaklarına Sahip Bir Evin Talep Karakteristiğine Uygun Bir İnverter Tasarımının İncelenmesi
Authors: SELAMOĞULLARI Ugur Savaş
Published: April 2019

Dünyamızın artan enerji gereksinimi
yenilenebilir enerji kaynaklarına olan ilgiyi artırmıştır. Özellikle, güneş ve
rüzgar enerjili güç sistemleri şebekeden bağımsız/şebeke bağlantılı evsel
uygulamalarda yaygın olarak kullanılmaya başlanmıştır. Yenilenebilir enerji
kaynaklarına sahip bir evde ihtiyaç duyulan sabit genlik ve frekansa sahip AC gerilimin
elde edilmesinde bir evirici (inverter) devre kullanılmaktadır. Bir evin
elektrik güç kullanımına ait ölçüm verisi incelendiğinde ev elektrik talebinin
gün boyunca değişken olduğu ve büyük bir oranda düşük güçlerde kaldığı görülmüştür.
Bu yüzden, böyle bir ev için inverter devresinin özellikle düşük güç
bölgesindeki verimin iyileştirilmesi gereklidir. Bu çalışmada, inverter devresinde
kullanılan LC filtre devresinde bulunan indüktör değerinin yük akımına göre değişken
olmasının inverter devresinin verimi üzerine etkisi incelenmiştir. Kullanılan
yöntemle inverter devresinden çekilen akımdaki dalgalanmanın düşürülebildiği ve
inverter devresinin düşük güçlerdeki veriminin büyük oranda iyileştirilebildiği
gösterilmiştir. Daha verimli bir inverter devresi ile yenilenebilir enerji
kaynaklarından elde edilen enerji daha etkin bir şekilde kullanılabilecektir.
Toward application of hierarchical structures by ultrashort pulsed laser ablation
Authors: Ackerl Norbert , Boerner Paul , Wegener Konrad
Published: April 2019

Surface structuring is a versatile tool to modify the physical interplay at the interface to gaseous or liquid media. The two industrial used approaches are, in general, a chemical modification via coating or/and an introduced topography. Here, the structuring is carried out with a direct technique using an ultrashort pulsed laser with infrared and green wavelengths. Two hierarchical structural units are generated at the surface on copper, aluminum, and an amorphous alloy. Structures in the micrometer regime are produced via 2.5D layered laser ablation. Laser induced periodic surface structures (LIPSSs), an inherent phenomenon of self-generated periodic features, can be utilized to generate subdiffraction limit features. LIPSSs are demonstrated in the high spatial frequency regime with a periodicity of 320 and 600 nm for green and infrared radiations, accordingly. This work concerns the use of direct laser structuring for potential applications. Specifically, a change in the optical and wetting properties is addressed. Broadband absorbing behavior and static contact angles of up to 152° are reported. Laser ablation processes and experimental routines are presented to upscale the structuring process. Production rates up to 100 mm2/h for 2.5D ablation and 0.6 m2/h for LIPSSs can be reached.
Functional features of neutrophils in subclinical hypothyroidism compared to euthyroid status
Authors: Mohan Bindu , Damodar Komaladevi Sampath
Published: April 2019

Neutrophil or polymorphonuclear leukocytes are critical to host defense. They act by migrating (chemotaxis) to site of inflammation or infection, phagocytoze the microorganisms to form phagosome. Reactive Oxygen species and hydrolytic enzymes are released (respiratory burst activity) into this phagosome to kill ingested microorganisms (microbicidal activity). Thyroid hormones are essential for proper differentiation, growth and metabolism of an organism. Increasing evidence indicates that thyroid hormones also play an active role in immunity. Subclinical hypothyroidism is associated with normal thyroid hormone levels with increased thyroid stimulating hormone level. While studies indicate elevated TSH to have some effects on immune functions, there is very little evidence regarding its effect on functional features of neutrophils. In this cross-sectional comparative study, we evaluated the phagocytic, chemotactic, candidacidal, and respiratory burst activity of neutrophils in subclinical hypothyroid and euthyroid subjects. Phagocytosis and metabolic function of the neutrophils was assessed using Nitro-blue tetrazolium test. Chemotaxis, directional movement of the PMNs was measured using the N-Formyl methionyl-leucyl-phenylalanine as chemoattractant. Phagocytic activity was evaluated by exposing leukocytes to candida suspension and counting the number of candida ingested and killed. Microbicidal activity of neutrophils was assessed by the ability of leukocytes to kill Candida albicans in both subclinical hypothyroid and euthyroid subjects. Our study demonstrated that chemotactic and mean phagocytic activity was significantly less in those with subclinical hypothyroidism as compared to euthyroid control group (p value = 0.005 and 0.045 respectively). Respiratory burst activities of both unstimulated & stimulated neutrophils were relatively reduced in subclinical hypothyroidism (p value of 0.08 and 0.07). Candidicidal activity was similar in both groups. We conclude that subclinical hypothyroid individuals having excess of thyroid stimulating hormones are associated altered functional characteristics of neutrophils.

Published: April 2019

Se propone repensar los relatos digitales personales (RDP) con las nuevas formas de comunicación, basadas en los contenidos que aparecen en las redes sociales, así como el valor central de la imagen en todos ellos. En primer lugar se ha intentado mapear las principales funciones de los RDP en el Plan Curricular de la Educación Secundaria, de 11 a 16 años, y algunas de las competencias asociadas. En segundo lugar se ha construido una encuesta sobre las formas de publicación en esas mismas redes. Los resultados son analizados, obteniéndose algunas diferencias por edad, país y sexo, si bien con grandes dosis de similitud. Finalmente, se propone algunas sugerencias didácticas sobre cómo incorporar los resultados de la encuesta.

Authors: Santo Nicola Rosane De Mello , Vosgerau Dilmeire Sant Anna Ramos
Published: April 2019

Esta revisão narrativa busca identificar o tratamento dado ao conceito de competência e seus enfoques nas pesquisas brasileiras. É referencial teórico a revisão de literatura de Gámez (2004) em contexto europeu. A busca na SciELO utilizou o descritor “conceito de competência” e artigos apresentados na íntegra, por pesquisadores brasileiros, obtendo 79 trabalhos de 1997 a 2013. Aplicados critérios de inclusão e exclusão, restaram 48 artigos e 8 ensaios científicos. Encontrados 61 conceitos, 20 características e 7 grupos de exemplos de competências, são resultados: na educação, a crítica ao modelo de competências, e recentemente, a proposta contra-hegemônica de matriz crítico-emancipatória; na formação inicial em saúde e administração, os órgãos normativos divergem entre as perspectivas construtivista, orientada para atributos pessoais, e a crítico-emancipatória; e na qualificação e educação profissional, busca-se articulação da construção social das competências com o campo pedagógico.
CINEMA NA ESCOLA: UMA MÁQUINA DE GUERRA CONTRA A VIOLÊNCIA PERFORMÁTICA NARCISISTA?
Authors: Corrêa Mirele , Monteiro Alexandrina
Published: April 2019

No contexto atual das políticas de currículo se vê proliferar nas escolas um novo gerencialismo que sai do setor privado e invade o setor público com vistas a qualificar o processo de gerência e melhorar os resultados. Esse novo gerencialismo, conforme Ball (2006) vai produzindo uma cultura da performatividade, constituindo corpos cada vez mais preocupados com os resultados, o desempenho e a qualificação de si. Mas, para além de um corpo-performático e polivalente, a cultura da performatividade produz uma violência narcisista a nível das pequenas diferenças correlatas à produção e a exclusão do outro no contexto escolar. O que se pretende com esse texto é pensarmos a contingência das violências produzidas pela escola contemporânea através da cultura da performatividade, e no contrafluxo, questionar: pode o cinema se colocar como máquina de guerra na produção de linhas de fuga aos desejos imanentemente agressivos no sentido de potencializar outra ética para a existência que exceda a da lógica neoliberal performática? Chamamos para a discussão e composição desse pensamento alguns teóricos da perspectiva pós-estruturalistas: Foucault (1999, 2008, 2010), Deleuze (1988, 2013), Ball (2003, 2010), Skliar (2016), e outros que se debruçam nos estudos focados em cinema: Miranda (2015, 2016), Migliorin (2015), Oliveira Jr, (2016), Gonçalves (2014). Acreditamos que por meio de algumas experiências desenvolvidas pelo Laboratório de Estudos Audiovisuais-OLHO, novas pistas podem ser seguidas de forma a construir através do cinema outros corpos, outras éticas, outros modos e estilos de ser e estar na vida.

The objective of the present study was to determine genetic diversity among three geese color types using RAPD markers and hematological parameters. The overall mean, of the live weights, Hemoglobin, Hetrophil %, Lymphocyte %, Monocyte %, and H/L ratio were 3.006 (kg), 14.64, 36.896, 49.896, 2.233 and 0.736 respectively. The breed, sex and interaction between them have a significant effect on live body weight, Hemoglobin, and Monocyte %. Ten primers were used and six out of them were selected based on their number of bands (NB) and polymorphic characteristics. A total of 309 bands observed, ranged from 30 in primer OPB-07 to 54 bands in OPA-20. Five unique bands were found only in white goose, whereas the highest unique band was obtained in primer OPB-01 locus. Overall genetic distance among native geese arrived 64.122 and phylogenetic dendrograms showed that 3 clusters, the first cluster content only white geese (Male and Female) breed, the second one cluster is included piebald geese breed (Male and female) and the third one was including gray geese (Male and female) breed. It was concluded that the white geese was closer to piebald geese than to the gray geese breed. The high genetic distance (64.122%) and variation in phenotypic value such as live weight (2.375 to 3.600 kg/bird) for three native geese indicate that these native geese have a good amount of genetic resources to made genetically improvement in further and it means the three goose samples are independent breeds.
Heart Half Implementation Sharia Banking In Indonesia

Islamic banking in Indonesia has been regulated in the law, namely Law number 10 of 1998 concerning amendments to Law number 7 of 1992 concerning banking. As time goes by, the existing Islamic banking practices are starting to be questioned, questioned, and criticized, because there are those considered deviant even out of the sharia corridor itself. Against various problems that exist in Islamic banking, it needs to be addressed appropriately. By understanding the nature of the principle of tadrij fii tasyri, we are required to better understand and focus on the processes and stages in the implementation of syariah banking. So that with all the problems of Islamic banking faced now, it must be understood that this is still the stages, not the end and purpose of the application of Islamic banking it self. However, the main problem in the implementation of Islamic banking is the commitment. Islamic banking is in a comfortable zone with its current format. Efforts to implement Islamic banking are still half-hearted, even less serious. Even though there is a lot of criticism embedded in Islamic banking, starting from the practice of improper contracting, Human Resources (HR) who are not competent with the sharia itself, and banking products that are less adaptive and responsive. Keywords: Implementation, Commitment, HR, Product and Agreement, Tadrij fii Tasyri
THE RELATIONSHIP BETWEEN INTERNAL MARKET ORIENTATION AND EMPLOYEE JOB SATISFACTION: THE CASE OF THE ROMANIAN BANKING SECTOR
Authors: NAGHI Remus Ionuț , PREDA Gheorghe , DRAGOMIR Anca Cristina
Published: April 2019

The paper aims to investigate the effect of internal market orientation and its dimensions on the employee job satisfaction. The idea of this research emerged from the extensive scientific literature that suggests the existence of a relationship between internal market orientation and employee job satisfaction. In fact, internal market orientation is conceptualized as a set of managerial behaviors that have the potential to influence employee behavior which would in turn affect customer satisfaction. The research involves a questionnaire-based survey of employees in the banking sector in Romania. The convenience sampling method was used. A total of 170 usable questionnaires were received from the employees. The measurement scales within the proposed model were evaluated for reliability and validity. The research hypotheses were tested via linear regression. The study’s empirical results suggest a positive influence of the internal market orientation and each of its three dimensions on employee job satisfaction. In order to increase the level of employee job satisfaction, the organization should systematically monitor the personal needs of every employee, to adapt every important decision taken by the managers to the individual needs that employees of different groups may have, supervisors should be interested in listening to what subordinates have to say about jobs, about the issues they have and the management of the organization must seriously consider employees’ needs, introduce policies and allocate funds to meet these needs.

Communication was born at the same time with humanity, and with the progression of historical ages the range of communication opportunities has become more widespread. Communication has the power, whether transmitted by words, images or even behavior, to shape the individual and thus the society. The greatest power of communication is its shaping potential. Individuals, organizations, companies, and governments are aware that what is being conveyed has an impact on the social values, but they also play a role in promoting societal problems, as empathy is the cornerstone of a healthy society. This article analyzes the following: (1) by what means and how did the communication of the expectations on women change during history (physical values/values regarding the appearance); (2) identifying the social problems of advertising campaigns; (3) the main guiding principle of Apple, Huawei and Samsung's advertising: the focus of their communication; (4) the values determined by Julia Roberts and the brands she represents; (5) the social problems promoted by world brands. The focus of the analyzes is on women, because women play a significant role in the implementation and solution of values and social problems, they also have an important role to play if they do not fight in the front line, but they are behind the scenes.

Sociología y regímenes autoritarios. La Carrera de Sociología de la UBA y los circuitos académicos alternativos durante los “años de plomo”
Authors: Blois Juan Pedro
Published: April 2019

Este artículo busca analizar el desarrollo de la sociología argentina durante el período iniciado a mediados de 1974 con la intervención represiva de las universidades y continuado luego por la dictadura militar. Con base en una perspectiva sociohistórica, el artículo hace foco en lo ocurrido en la carrera de Sociología de la Universidad de Buenos Aires (UBA) y en las principales instituciones alternativas: los centros de investigación privados y las universidades privadas. El análisis, basado en distintos materiales documentales y entrevistas, procura dar cuenta de los efectos del contexto represivo en la práctica de la sociología y sus instituciones. Se mostrará cómo las dificultades para llegar a públicos o clientelas más amplios impulsaron el desarrollo de una sociología crecientemente “ensimismada”, cuya relevancia o pertinencia social no siempre resultaba clara para sus propios cultores.
