This article summarizes the main elements, advantages, and disadvantages of Respondent-driven Sampling (RDS). Some criticisms regarding the feasibility of the inherent assumptions, their point estimators, and the obtained variances are pointed out. This article also comments on the problems observed in the quality of reports. Surveys using RDS should be methodologically sound as they are being applied to define priorities in health programs and develop national and international policies for financing service delivery, among other uses. However, there is considerable potential for bias related to implementation and analytical errors. There is limited empirical evidence on how representative the results obtained by RDS are, and the quest to improve the methodology is still in progress. Nevertheless, to have confidence in RDS results, we must verify that the social structure of the networks conforms to the assumptions required by the theory, that the sampling assumptions are reasonably fulfilled, and that the quality of the report is optimal, particularly for methodological and analytical items.

Depth Interviews

The study investigates the changes taking place in the domestic market of social services expressed in the appearance of "new players" in the form of socially oriented non-profit organizations (SO NPO) within its field in addition to public institutions for social protection and social services of the population. The authors identify the advantages and disadvantages of SO NGO compared to government organizations and social services, describe the processes of shadow economy expansion to the social services market and formation of regional "quasi-markets". The empirical part of the article is based on the data of two studies conducted in the form of indepth interviews. First, with experts on "Practices of interaction and prospects of cooperation between NPO and government organizations of social services in the Volgograd region", N = 52 (27 representatives of the public sector, 25 representatives of NPO, January-March 2018). Then with recipients of social services from government organizations and clients of SO NPO on the theme "Availability and quality of paid and free social services provided in the Volgograd region for retiring aged women" N = 46, 60 years and older (21 people-clients of SO NPO, 25 people-recipients of social services. services, October 2017 – January 2018). The analysis of these in-depth interviews with experts allowed to draw the following conclusions. There is a duplication of functions of the organizations of public and non-public sectors providing social services to the population. The activities of modern SO NPO operating in the social services market contain innovative and commercial components. The expansion of the "platform" of the social services market does not yet lead to full competition between organizations, encouraging them to constantly improve the quality of services. The analysis of in-depth interviews with recipients of social services from government organizations and customers of SO NPO showed that the commercialization of activities of SO NPO does not make social services more accessible to those who are in need of them. There is the necessity of changes in the way social services are being provided in the Volgograd region as they do not meet the needs of women of retirement age, do not take into account their level of income and material well-being.

The preregistration of research protocols and analysis plans is a main reform innovation to counteract confirmation bias in the social and behavioral sciences. While theoretical reasons to preregister are frequently discussed in the literature, the individually experienced advantages and disadvantages of this method remain largely unexplored. The goal of this exploratory study was to identify the benefits and challenges of preregistration from the researcher's perspective. To this aim, we surveyed 355 researchers, 299 of whom had used preregistration in their own work. The researchers indicated the experienced or expected effects of preregistration on their workflow. The results show that experiences and expectations are mostly positive. Researchers in our sample believe that implementing preregistration improves or is likely to improve the quality of their projects, and that preregistration makes it easier to avoid questionable research practices. Criticism of preregistration is primarily related to the increase in work-related stress and the overall duration of the project. The majority of researchers with experience in preregistration reported that the benefits outweigh the challenges. However, the majority of researchers without preregistration would not consider preregistration for future projects or recommend the practice to colleagues. Our interpretation of the results is that preregistration can have positive side-effects as it adds an extra preparatory step in researchers' workflow, thus requiring researchers to think through the theoretical and practical aspects of their project.

Milkfish nugget is one of nutritionally dense processed with a practical presentation and generally liked by children. To enrich the nutritional content, the manufacture of nuggets is modified with the addition of vegetables including carrots and sweet corn. The modification of milkfish nuggets with carrots and sweet corn can be used as additional food for underweight toddlers This study aims to determine the effect of milkfish nuggets formulation with carrots and sweet corn modification. This research was a quasi-experiment with one group pre and post-test design. The sample was 37 with the total sampling method. The data was collected by observing the enhancement of toddlers’ nutritional status during 10 days. Data were analyzed by using a paired T-test with a  95% confidence interval. The results showed the bodyweight average increase after giving milkfish nuggets was 800 grams with an enhancement in nutritional from the average Z-score value of -1,95 through the bodyweight for age indicator. The milkfish nuggets formulation had a significant effect in enhancing the nutritional status of underweight toddlers (p-value 0,002). It is necessary to improve the quality of health programs especially regarding food intake for underweight toddlers to achieve the quality of the human development index.

The article is devoted to the features of the formation of the organizational and economic model of the construction of a socio-commercial multifunctional complex for high-rise construction. Authors have given examples of high-altitude multifunctional complexes in Moscow, analyzed the advantages and disadvantages in the implementation of multifunctional complexes, stressed the need for a holistic strategic approach, allowing to take into account the prospects for the development of the city and the creation of a comfortable living environment. Based on the analysis of multifunctional complexes features, a matrix of SWOT analysis was compiled. For the development of cities and improving the quality of life of the population, it is proposed to implement a new type of multifunctional complexes of a joint social and commercial direction, including, along with the implementation of office areas - schools, polyclinics, various sports facilities and cultural and leisure centers (theatrical, dance, studio, etc.). The approach proposed in the article for developing the model is based on a comparative evaluation of the multifunctional complex project of a social and commercial direction implemented at the expense of public-private partnership in the form of a concession agreement and a commercial multifunctional complex being built at the expense of the investor. It has been proved by calculations that the obtained indicators satisfy the conditions of expediency of the proposed organizational-economic model and the project of the social and commercial multifunctional complex is effective.

When interacting on a learning task, which is typical of several academic situations, individuals may experience two different motives: Understanding the problem, or showing their competences. When a conflict (confrontation of divergent propositions) emerges from this interaction, it can be solved either in an epistemic way (focused on the task) or in a relational way (focused on the social comparison of competences). The latter is believed to be detrimental for learning. Moreover, research on cooperative learning shows that when they share identical information, partners are led to compare to each other, and are less encouraged to cooperate than when they share complementary information. An epistemic vs. relational conflict vs. no conflict was provoked in dyads composed by a participant and a confederate, working either on identical or on complementary information (N = 122). Results showed that, if relational and epistemic conflicts both entailed more perceived interactions and divergence than the control group, only relational conflict entailed more perceived comparison activities and a less positive relationship than the control group. Epistemic conflict resulted in a more positive perceived relationship than the control group. As far as performance is concerned, relational conflict led to a worse learning than epistemic conflict, and - after a delay - than the control group. An interaction between the two variables on delayed performance showed that epistemic and relational conflicts were different only when working with complementary information. This study shows the importance of the quality of relationship when sharing information during cooperative learning, a crucial factor to be taken into account when planning educational settings at the university.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

Cloud computing has been envisioned as the definite and concerning solution to the rising storage costs of IT Enterprises. There are many cloud computing initiatives from IT giants such as Google, Amazon, Microsoft, IBM. Integrity monitoring is essential in cloud storage for the same reasons that data integrity is critical for any data centre. Data integrity is defined as the accuracy and consistency of stored data, in absence of any alteration to the data between two updates of a file or record.  In order to ensure the integrity and availability of data in Cloud and enforce the quality of cloud storage service, efficient methods that enable on-demand data correctness verification on behalf of cloud users have to be designed. To overcome data integrity problem, many techniques are proposed under different systems and security models. This paper will focus on some of the integrity proving techniques in detail along with their advantages and disadvantages.

Quality of life and satisfaction with life as tightly interconnected concepts have become of much importance in the urbanism era. No doubt, it is one of the most important goals of every human society to enhance a citizen’s quality of life and to increase their satisfaction with life. However, there are many signs which demonstrate the low level of life satisfaction of Iranian citizens especially among the youth. Thus, considering the temporal concept of life satisfaction, this research aims to make a futures study in this field. Therefore, using a mixed model and employing research methods from futures studies, life satisfaction among the students of the University of Tehran were measured and their views on this subject investigated. Both quantitative and qualitative data were analysed together in order to test the hypotheses and to address the research questions on the youth discontentment with quality of life. Findings showed that the level of life satisfaction among students is relatively low and their image of the future is not positive and not optimistic. These views were elicited and discussed in the social, economic, political, environmental and technological perspectives. Keywords:  futures studies, quality of life, satisfaction with life, youth
