Published: July 2019

BACKGROUND

Given that more than half the world’s population report feelings of meaninglessness and that access to psychological services are limited or expensive, psychologists need to develop innovative and scalable means to provide psychological services to those in need. Social media platforms provides an innovative channel through which to administer, track and scale brief positive psychological interventions aimed at aiding individuals to finding meaning and purpose in their lives. Instagram, a visual ethnographic platform, could be used as a means to aid individuals to discover the sources of meaning in a structured and systematic manner.

OBJECTIVE

The purpose of this study was to develop an intervention protocol for a brief online photographic meaningful-moments intervention aimed at enhancing meaning in life through Instagram. This study builds upon the pilot study of Steger et al. (2014) through not only looking at the short-, medium-, and long-term efficacy of the intervention, but also employing social media (Instagram) as an intervention platform.

METHODS

A pre-experimental mixed-method longitudinal intervention design was employed to investigate the effectiveness of the intervention. Quantitatively, a four x treatment group design, employing an online psychometric assessment methodology, was used to assess changes in the study variables over time (a week before-, directly after-, three months after and one year after the completion of the intervention). Qualitatively, data was obtained through both the photos taken and the personal reflections thereon. The Mobile Phone Visual Ethnography approach was employed to gather visual images and textual data relating to the meaningful moments experienced by participants. A post-positivistic (Visual Voice) Interpretative Phenomenological Analytical strategy was employed to analyse the textual data obtained through the personal reflections of the participants (in the context of the visual images).

RESULTS

The effect the intervention will be evaluated through tracking changes in meaning, life satisfaction, depression/stress/anxiety, and gratitude over time. Further, it aims to understand the personal sources of meaning of participants during the intervention.

CONCLUSIONS

The study will add knowledge as to the efficacy of a brief, scalable positive psychological intervention aimed at enhancing meaning through social media. Further, it will provide evidence as to the sources of meaning in peoples lives.

The background of this research  not all students like physics learning. This is caused by students' lack of understanding of physics learning material. The students' incomprehension can be seen when the learning process takes place, some students are embarrassed to ask even though basically the students do not understand the material presented by the teacher in front of the class. This type of research is Quasi Experiment with research design in the form of Design Group Control. Data on physics learning results are seen in two domains, namely the cognitive and affective domains. In the cognitive domain, the average experimental class has an average of 67.37 while the class has an average of 60.76. Learning outcomes in the affective domain obtained from the assessment of student activity sheets had an average of 79 in the experimental class and 74 in the control class. Based on the results of the analysis of hypothesis testing with the F test, it was found that t count = 1.64, and t table = 2.00, where if –t table < t count < t table then the hypothesis is rejected. So it can be concluded that the use of cooperative learning model type Group Investigation does not affect the learning outcomes of physics students of class XI MIPA SMAN 1 Enam Lingkung.

Authors: DJALİLOVA Natalia
Published: July 2019

This article analyzes the piano Trio INO-3 V. Rotaru, its significance
in the author's work, the basic style, the harmonic, rhythmic and inerprtative
aspects. The connection with neo-folklore direction in music and traditional
genres in Moldovan folk music is revealed, the synthesis of traditional folklore
with modern composition techniques.This article assumes to define first of all value of the considered Trio
INO-3 in the context of all area of chamber-instrumental music of V. Rotaru, as
the last composition of the composer in this genre sphere. The article also
focuses on the neo-folklore features of the composer's style and their
harmonious combination with the classical traditions typical of the trio of
Russian and Western European composers. As for the classical traditions, the
Trio is a three-part cycle with a characteristic tempo dramaturgy:I. ModeratoII.         Lento
e molto lamentoIII.         Allegro
moderatoSince this Trio is the last in the cycle and was
written shortly before the composer's death, the author's appeal to the genre
of mourning Saraband in the middle part is of interest. As for the neo-folk
style elements, they define the whole thematic, rhythmic and Lado - harmonic
material of the composition. The article focuses on the Lado - harmonic
features of all parts of the Trio, which are characteristic intonation formulas
of Moldovan folklore: motives with II increased and decreased levels, motives
with IV increased level, VI increased level, enriched with melismatics. From
the point of view of rhythm, the composer relies on the rhythmic formulas of fast
Moldovan dances, with variable meters and changing accents. The ensemble
texture goes back to the classical traditions, which consist in frequent
variation of thematism transmitted from one member of the ensemble to another,
as well as in rich polyphonic techniques such as imitation, Canon and
contrasting polyphony. In General, the trio INO3 is a concert composition with
vivid figurative contrasts, which is worthy of being in demand in pedagogical
and concert practice in our country and abroad.

Published: July 2019

This study examines the impact of thirteen mergers and acquisitions in the Greek banking sector which took place during the period of economic crisis: 2008-2014. More specifically, the sample of this study consists of all the mergers and acquisitions that led to the four remaining Greek banks (the acquirers of the above-mentioned transactions) which are: National Bank of Greece, Piraeus Bank, Eurobank and Alpha Bank. These specific banks were chosen due to the fact that after the M&As transactions we were able to compare their financial data. This comparison was made by using eight ratios for statistical tests one-year pre- and post-merger. The results of the study indicate statistically significant improvement in three capital structure and viability ratios, as well as a slight improvement on a liquidity ratio, while there is statistically insignificant change or no improvement on the profitability and efficiency ratios. In conclusion, there was some improvement in terms of capital adequacy and loan structure as far as the total capital employed of the merged institutions is concerned, but without improving the profitability of the banks during the economic crisis in Greece.

Authors: Mladenovic-Segedi Ljiljana , Bjelica Artur
Published: July 2019

Introduction. The aim of this study was to examine the quality of life and
psychological state of women with genital warts. Material and Methods.
Three questionnaires have been used to evaluate the quality of life: the
generic questionnaire European quality of life index version 5D,
disease-specific questionnaire for Condylomata Acuminata, and dermatology
life quality index. Results. The average age of patients was 29.72 +/- 8.54
years. The most common location of genital warts was the vulva (33.8%) and
then vulva and vagina (22.54%). The mean value of the visual analogue scale
was 70.37 +/- 20.8. The mean value of the specific questionnaire for
Condylomata Acuminata-10 questionnaire was 26.61 +/- 10.09. The patients
with higher scores in specific questionnaire for Condylomata Acuminata-6 and
-10 questionnaires evaluated their quality of life as significantly better
(specific questionnaire for Condylomata Acuminata-10: r = 0.251; p < 0.05)
(specific questionnaire for Condylomata Acuminata-6: r = 0.263; p < 0.05).
The mean score of the dermatology life quality index questionnaire was 6.42
+/- 5.82. About 81.4% of women were concerned, anxious and depressed, 54.3%
felt pain and discomfort in the genital region, and 57.7% suffered from
itching and burning. Shame and insecurity was reported by 64.8% of
patients. About 50.7% had a problem with genital warts that affected their
relationship, while 62.1% had problems with sexual intercourse. Conclusion.
Our examination showed that genital warts adversely affected the emotional
and sexual aspects of the quality of life. There is a need for better
education of the general population on human papillomavirus infection and
its prevention.
Effects of Mg2+ addition on structure and electrical properties of gadolinium doped ceria electrolyte ceramics
Authors: Cheng Jihai , Tian Changan , Yang Jie
Published: July 2019

Series of Gd3+ and Mg2+ co-doped ceria (Ce0.8Gd0.2-xMgxO1.9-?) powders were
prepared by a sol-gel method and electrolyte ceramics were obtained by
sintering at 1300?C. Thermogravimetric and differential scanning
calorimetry, X-ray diffraction, scanning electron microscope and
electrochemical impedance spectroscopy were used for structural, morphology
and electrical characterization of the prepared samples. Well crystalline
cubic fluorite structured composite was confirmed after calcination at 700?C and the electrolyte ceramics sintered at 1300?C for 4 h was quite dense
with uniform microstructure. The electrochemical analysis results displayed
that the highest conductivity has the Ce0.8Gd0.14Mg0.06O1.87 compound, i.e.
0.0203 S/cm at 800?C. Therefore, it was concluded that co-doping with Gd3+
and Mg2+ could enhance the electrical properties of the CeO2 based solid
electrolytes.

Published: July 2019

In this study, five foamed ceramics with struts containing needle-like
mullite were prepared by direct-foaming method using white clay, industrial
alumina and microsilica powder as raw materials. The effects of microsilica
content on the phase compositions, microstructures and properties of foamed
ceramics were investigated. The results showed that the adding of
microsilica decreased the average pore size and apparent porosity and
increased the compressive strength and thermal conductivity of the foamed
ceramics by affecting the properties of foamed slurry and reaction sintering
process. The foamed ceramics with 10 wt.% microsilica content showed the
best properties with high porosity of 75.8%, positive reheating linear
change, compressive strength of 1.44MPa and low thermal conductivity of
0.219W/(m?K) (at 350?C).

Published: July 2019

The initial-stage of sintering plays a significant role in determining the
final microstructure that defines the main characteristics of
electroceramics materials such as functional properties. In this article
non-isothermal sintering of non-activated and mechanically activated SrTiO3
samples was investigated up to 1300?C. Dilatometric curves indicate that
mechanical activation leads to an earlier onset of sintering, suggesting
that it should lead to a more homogenous and denser sintered product.
Analysis of the initial stage of sintering reveals that the sintering
process of all examinated samples consists of tw? or three overlapping
single-step processes, with a change in the dominant mass transport
mechanism. The values of apparent activation energy of the considered
single-step process exhibit a significant decrease with an increase in
mechanical activation time. The values of the density of samples after
isothermal sintering indicate that the final stage of sintering has not been
reached by 1300?C.
Pasif Tümör Hedefli İnorganik İlaç Nanotaşıyıcıların Akciğer Sağlıklı ve Kanser Hücreleri Üzerindeki Uzun Dönemli Etkisi
Authors: DAĞLIOĞLU Cenk , KACI Fatma Necmiye
Published: July 2019

İlaç nanotaşıyıcıları, kontrollü ve
sürekli ilaç salım özellikleri ile kanser tedavisinde büyük bir potansiyele
sahiptir. Bu nanotaşıyıcılar pasif veya aktif hedefli olarak ilaç taşınımı
sağlayabilmektedir, ancak aktif hedefli muadillerine göre, pasif hedefli
nanotaşıyıcılar tümörlü dokularda daha yavaş ve düşük düzeyde ilaç birikimi
sağladığından kanserli hücrelerin yanında sağlıklı hücrelerde uzun süre bu
nanotaşıyıcılara maruz kalmaktadır. Bu nedenle, bu çalışmada, pasif hedefli
ilaç nanotaşıyıcıların insan akciğer epitel BEAS-2B hücreleri ve insan akciğer
kanser A549 hücreleri üzerindeki uzun dönem etkileri araştırıldı. Bunun için,
görüntüleme ve tedavi edici özellikleri bir arada barından Fe3O4@SiO2(FITC)-DOX
formülasyonuna sahip ilaç nanotaşıyıcıları kullanıldı ve hücresel birikim,
sitotoksisite ve apoptoz üzerindeki etkileri araştırıldı. Hücresel alım ve
sitotoksisite deneyleri, pasif hedefli nanotaşıyıcıların kanser hücresi canlılığının
etkin bir şekilde azalttığını gösterirken, 24 saatlik inkübasyon sürecinde
sağlıklı hücreler üzerinde kayda değer bir etki görülmedi. Ancak 96 saatlik
uzun inkübasyon sürecinde, sağlıklı BEAS-2B hücreleri makul seviyelerde
nanotaşıyıcı alımı gerçekleştirirken, A549 kanser hücrelerine kıyasla düşük
düzeylerde ilaç-aracılı sitotoksisite sergiledi. Ayrıca, nanotaşıyıcılar A549
hücrelerindeki apoptoz seviyelerini önemli ölçüde artırırken, BEAS-2B
hücrelerinde 96 saat sonunda dahi apoptotik etki göstermedi. Bu sonuçlar, pasif
hedefli inorganik ilaç nanotaşıyıcıların, sağlıklı hücreleri ihmal edilebilir
düzeyde etkileyerek,  antikanser
ilaçların kemoterapötik etkilerini artırmada umut verici olduğunu göstermektedir.
Laser rapid forming processing of TiC reinforced nickel-based superalloy composites: Influence of additive TiC particle content
Authors: Cao Sainan , Gu Hai , Yang Jianchun , Li Bin , Jiang Jie , Zhang Jie , Xu Ningping
Published: July 2019

The present investigation concerned the fabrication of TiC (2.5 and 5 wt. %) reinforced nickel-based superalloy (NBS) composites by laser rapid forming (LRF) with a high power diode laser. Furthermore, the evaluation of microstructures and the wear resistance of the laser manufacturing specimens were researched. There were four different species of microstructures in LRF-processed pure NBS parts and 2.5% TiC/NBS composites, including cellular grains, columnar grains, crosslike grains, and columnar dendrites. However, only cellular grains could be observed in the 5% TiC/NBS composite parts. Moreover, when micro-TiC particles were added as reinforcements, relatively coarsening microstructures were obtained by the LRF processing compared with the unreinforced NBS parts. Generally, the LRF-processed 5% TiC/NBS composites showed the best efficiency in improving the tribological property compared with the pure NBS and 2.5% TiC/NBS composite parts. It indicated that the dominant wear mechanism was adhesive wear when unreinforced NBS sliding against GCr15 counterpart ball, while 2.5% TiC/NBS composite underwent adhesive wear and abrasive wear simultaneously. However, the predominant wear mechanism of 5% TiC/NBS composite changed into abrasive wear. The energy dispersive x-ray spectroscopy analyses could be the evidence that oxidative wear also occurred between the sliding pair of TiC/NBS composites and GCr15 during the dry sliding wear test.

Published: July 2019

The tree improvement program has invented superior teak with an ability to improve its productivity. Yet the information about basic nutrient requirement of superior teak is less known. This study aimed to determine the optimal concentration of sulfur for the best growth of superior teak seedling and to identify the morphological symptoms of teak seedlings affected by several concentration levels of S. This study was conducted at a nursery on six months old teak seedlings. The experimental design was Completely Randomized Design (CRD) with four different solution treatments with three replication each. The treatments are K (control, aqua dest does not contain nutrients), S0 (solution contains nutrients except sulfur), S1 (solution contains nutrients with 0,5 full strength of S), and S2 (solution contains nutrients with full strength of S). Each treatment was replicated 3 times. Parameter observed included the height of seedling, the diameter of seedling, the nodal distance of seedling, the number of leaves, size of leaves and morphological symptoms of leaf. The results showed that at a concentration of nitrogen (N), phosphor (P), potassium (K), calcium (Ca), and magnesium (Mg) in full strength level, superior teak seedling which treated by S1 (S concentration of 421 ppm) resulted in the best growth. However, the morphology of teak leaves in all treatment showed abnormal.Keywords: growth, morphology, sulfur, superior teak

Increasing competition of good output which interpreted with GDP in developed and developing countries that are members of the G20, have some impact on the degradation of environmental quality. The Production of good output namely GDP cannot be separated from bad output’s production which is CO2. The need for the Kyoto protocol as an environmental policy which has been ratified by the G20 that supposing to control emission levels which can be measured by the measurement of the environmental efficiency of the G20 countries. Apart from the environmental efficiency, efficiency is not the main criterion for making a country to be standard for another country. On the other hand, the performance quality of the environment must also be taken into account. The amount of the cost of environmental policy to maximize environmental efficiency of a country but the environmental performance of the country, state inefficiency in the cost of the policy then the country has not been used in a cost-efficient technology for improving the environmental quality. The approach which has used in this study is a quantitative approach, using Data Envelopment Analysis (DEA). To specify the input and output that is used in determining the environmental efficiency using Malmquist Index. The input and output is processed by looking at differences in productivity and incorporate technological change in its interpretation. It can be concluded that the value of the environmental efficiency of some countries are on the production frontier even if the Kyoto protocol is not implemented, but with the policy of the Kyoto protocol was able to further improve the efficiency of the environment. In some other countries for example Brazil rose from 70.09% to 83.49%, while the Germany states increased by 4.43% in their environmental policy. From some countries evident  show that the policy of the Kyoto protocol succeeded in carrying out its role as controlling the growth of emissions in developed and developing countries, especially the G20 members.

This study attempt to examine the complex relationship between global consumer culture and global citizenship by involving the mediating effect of cultural intelligence behavior and the moderating effect of religiosity. The structural equation model was developed to propose some hypothesis with support from previous literature. The empirical analysis involved online survey at the individual level, who voluntarily contributed to respond the survey. They represent young people, who represent various places in Indonesia. The results indicate that global consumer culture has a positive impact on global citizenship with mediating support from cultural intelligence behavior. In addition, the moderating effect of religiosity shows that the individual with high level of religiosity demonstrates high level of global citizenship. However, increasing level of global consumer culture for such individual has less impact on global citizenship than individual who has low level of religiosity. This study extends the discussion on global customer culture, which becomes a main concern to international business.
Recuperando la memoria institucional. Algunas perspectivas sobre la historia reciente del Instituto Ravignani
Authors: Pagano Nora Cristina
Published: July 2019

El objetivo central del presente dossier, reside en reflejar una parte significativa de la actividad académica producida en el Instituto de Historia Argentina y Americana “Dr. Emilio Ravignani” durante la dirección de Ricardo Caillet Bois (1956-1973 y 1976-1977). La historia de la historiografía argentina abordó con distintos énfasis, problemáticas diversas centradas en variadas perspectivas analíticas, sin embargo existe un virtual vacío historiográfico sobre el desempeño del Instituto y sus derivas a partir de mediados del siglo XX. Tal vacancia contrasta con la centralidad institucional e historiográfica que la institución revistió. Consecuentemente aspiramos a contribuir a la recuperación de la memoria institucional mediante la reconstrucción de su estructura y funcionamiento, el conocimiento de los miembros que lo componían y las actividades desarrolladas, así como referir a los vínculos trazados con otras instituciones, fundamentalmente: la Universidad de Buenos Aires (UBA) y la Facultad de Filosofía y Letras de la Universidad de Buenos Aires (FFyL), vínculos enmarcados en precisas coyunturas históricas.
