To understand the status quo of urban recurrent traffic congestion, the current results of recurrent traffic congestion, and gating control are reviewed from three aspects: traffic congestion identification, evolution trend prediction, and urban road network gating control. Three aspects of current research are highlighted: (a) The majority of current studies are based on statistical analyses of historical data, while congestion identification is performed by acquiring small-scale traffic parameters. Thus, congestion studies on the urban global roadway network are lacking. Situation identification and the failure to effectively warn or even avoid traffic congestion before congestion forms are not addressed; (b) correlation studies on urban roadway network congestion are inadequate, especially regarding deep learning, and considering the space-time correlation for congestion evolution trend prediction; and (c) quantitative research methods, dynamic determination of gating control areas, and effective countermeasures to eliminate traffic congestion are lacking. Regarding the shortcomings of current studies, six research directions that can be further explored in the future are presented.

Field research can be associated with both qualitative and quantitative research methods, depending on the problems faced and the goals to be achieved. The success of data collection in the field research depends on the determination of the appropriate sampling technique, to obtain accurate data, and reliably. In studies that have problems related to specific issues, requiring a non-probability sampling techniques one of which is the snowball sampling technique. This technique is useful for finding, identifying, selecting and taking samples in a network or chain of relationships. Phased implementation procedures performed through interviews and questionnaires. Snowball sampling technique has strengths and weaknesses in its application. Field research housing sector become the case study to explain this sampling technique.

Research uses quantitative research methods through surveys on 300 FSRD students. The samples in this study were 271 FSRD UNS students. Sampling in this study using a proportional random sampling cluster technique i.e. the determination of sample members is carried out randomly by voting the class of each department. The data collection techniques used are psychological scales. The results showed that Fcount value is 42.303 (Fcount> Fttable 3.026) with sig. 0,000 (p <0.05) and the R value is 0.471, which means the correlation is on moderate level. The R square value is 0.222 indicating the effective contribution is 22.16%, with effective contribution of social support is 2.8% and task commitment is 19.36%.

This paper analyses key differences between two paradigms dominant in social research on online crime: the more prevalent neopositivist paradigm and the more recent critical–cultural paradigm. Based on an extensive analysis of up-to-date literature, the key paradigmatic oppositions in online crime research encompass: 1) in neopositivism, the conceptual separation of technological and social practices, the reliance on rational choice approaches in theory, especially routine activity theory, and the tendency towards quantitative research methods; 2) in the critical–cultural paradigm, a complex and context-dependent approach to the technosocial as a continuum, theoretical roots in critical theory, cultural criminology, actor-network theory, and feminist theory, and the emphasis on qualitative methods. The field of online crime research in Lithuania is dominated by legal studies, while social research is rare and fragmented. The existing social research of online crime in Lithuania lacks a solid theoretical basis in either paradigm. Methodologically, there are examples of both quantitative (surveys, analysis of registered crime statistics) and qualitative studies (interviews, discussion groups, content analysis). However, most of the studies are small-scale and their scarcity makes it nearly impossible to evaluate the strengths, weaknesses, and complimentary potential of each approach in the specific national and regional context.

Engaging part-time Master of Education students in the study of quantitative research methods is challenging. The majority of them lead busy lives as teachers and/or education leaders, attend their MEd classes in the evenings and plan to engage in small-scale qualitative research for their theses. In this context, it has been hard to motivate students to engage critically and deeply with quantitative research methods. A widespread deficit view of their own competency in mathematics and computing, which are often considered essential, further compounds the problem. This paper describes the redesign of a quantitative methods module and the resulting changed experiences of students. Findings from this practitioner research study point to the positive impact of using a real national data set – the Growing Up in Ireland Dataset – on students’ engagement and appreciation of the value of quantitative research in education.

The general aim of the study is to investigate the different attitudes and perceptions of middle level managers with regard to sources of job satisfaction, sources which contribute to job dissatisfaction, and to job stress. In this regard it was decided to make use of triangulation by which qualitative and quantitative research methods are used. Thematic analysis is used on the qualitative level to identify the possible sources of job satisfaction, dissatisfaction and job stress. This method is quantitatively supported by a determination of the frequencies and percentages of subject responses by means of semi structured interviews. On the qualitative level it was found that the experience of success is rated as the most important source of job satisfaction and that interpersonal relationships are the most significant source of job dissatisfaction. Finally it seems that work expectations/ demands appear to be the major source of job stress. Opsomming Die algemene doelstelling van die studie is om ondersoek in te stel na die verskillende houdings en persepsies van middelvlak-bestuurders rakende werkstevredenheid, sowel as die bronne wat bydra tot werkstres en werksontevredenheid. In dié verband is besluit om van triangulasie gebruik te maak. Op die kwalitatiewe vlak word tematiese analise gebruik om potensiële bronne van werkstevredenheid, ontevredenheid en werkstres te identifiseer. Hierdie metode word verder kwantitatief ondersteun deur ‘n bepaling van frekwensies en persentasies van subjekte se reponse wat uit semi-gestruktureerde onderhoude verkry is. Op die kwalitatiewe vlak blyk dit dat die ervaring van sukses die grootste bron van werkstevredenheid is en dat interpersoonlike verhoudings die bron is wat die meeste bydra tot ontevredenheid. Verder blyk dit dat werksverwagtinge/-eise die grootste bron van werkstres is.
