Clickstream Data Analysis: A Clustering Approach Based on Mixture Hidden Markov Models
2023
Nowadays, the availability of devices such as laptops and cell phones enables one to browse the web at any time and place. As a consequence, a company needs to have a website so as to maintain or increase customer loyalty and reach potential new customers. Besides, acting as a virtual point-of-sale, the company portal allows it to obtain insights on potential customers through clickstream data, web generated data that track users accesses and activities in websites. However, these data are not easy to handle as they are complex, unstructured and limited by lack of clear information about user intentions and goals. Clickstream data analysis is a suitable tool for managing the complexity of t…
Between models and narratives: transitions in settlement systems

About time
2019
Purpose The purpose of this paper seeks to develop a motivation-based complementary framework for temporally dynamic user preferences to facilitate optimal timing in web personalisation. It also aims to highlight the benefits of considering user motivation when addressing issues in temporal dynamics. Design/methodology/approach Through theory, a complementary framework and propositions for motivation-based temporal dynamics for further testing are created. The framework is validated by feeding back findings, whereas some of the propositions are validated through an experiment. Findings The suggested framework distinguishes two ways (identifying/learning and shifting) of using a motive-base…
Elucidating geological and biological processes underlying the diversification of Sulawesi tarsiers.
2009
Because of their exceptionally long independent evolution, a range diminution of their Eocene relatives, and a remarkable subsequent diversification in Southeast Asia, tarsiers are of particular importance to evolutionary primatologists. Little is known, however, on the processes shaping the radiation of these small enigmatic primates—especially on the Indonesian island of Sulawesi, their center of endemism. Geological reconstructions and progress in applying DNA sequence information to divergence dating now provide us with the tools and background to comprehend tarsier dispersal. Here, we describe effects of plate-tectonic movements, Pleistocene sea level changes, and hybridization on the…
Towards a comprehensive understanding of new regional industrial path development
2019
Path creation is a key concept in economic geography. So far, particularly scholars within evolutionary economic geography have pioneered research on this topic. This paper critically discusses the...
A visualization technique for accessing solution pool in interactive methods of multiobjective optimization
2015
<pre>Interactive methods of <span>multiobjective</span> optimization repetitively derive <span>Pareto</span> optimal solutions based on decision maker's preference information and present the obtained solutions for his/her consideration. Some interactive methods save the obtained solutions into a solution pool and, at each iteration, allow the decision maker considering any of solutions obtained earlier. This feature contributes to the flexibility of exploring the <span>Pareto</span> optimal set and learning about the optimization problem. However, in the case of many objective functions, the accumulation of derived solutions makes accessing the sol…
Multilevel Latent Profile Analysis With Covariates : Identifying Job Characteristics Profiles in Hierarchical Data as an Example
2018
Latent profile analysis (LPA) is a person-centered method commonly used in organizational research to identify homogeneous subpopulations of employees within a heterogeneous population. However, in the case of nested data structures, such as employees nested in work departments, multilevel techniques are needed. Multilevel LPA (MLPA) enables adequate modeling of subpopulations in hierarchical data sets. MLPA enables investigation of variability in the proportions of Level 1 profiles across Level 2 units, and of Level 2 latent classes based on the proportions of Level 1 latent profiles and Level 1 ratings, and the extent to which covariates drawn from the different hierarchical levels of th…
A person-oriented approach to diary data. Children’s temperamental negative emotionality increases susceptibility to emotion transmission in father-c…
2015
The notion that some individuals are more prone to emotion transmission than others has prompted the need for a person-oriented approach to emotion transmission in parent-child dyads. The present study applied a person-oriented analysis to examine the patterns of emotion transmission that can be identified in the diary data of father-child dyads, and the extent to which children with high levels of temperamental negative emotionality are particularly susceptible to emotion transmission within the family. Mothers of 149 first grade children (age 6 to 7) completed questionnaires concerning their child’s temperament. Mothers and fathers maintained diary questionnaires (for a total of 7 days) c…
Professional agency in a university context: Academic freedom and fetters
2020
Professional agency is an urgent topic in academic contexts, albeit relatively unexplored, and elaborated with contradictory conclusions on its extent and characteristics. To contribute to the discussion, this multimethod study investigated professional agency within a Finnish university. We utilised questionnaire data and interviews to explore agency, as manifested in influencing at work, developing work practices, and negotiating professional identity. We found that overall, these three dimensions of agency were manifested fairly substantially, and in a similar manner among the academic staff. The study further emphasises the social nature of professional agency, and presents theoretical …
