Work–family conflict and psychological well-being: Stability and cross-lagged relations within one- and six-year follow-ups
2008
Abstract The rank-order stability and cross-lagged relations between work-to-family conflict (WFC), family-to-work conflict (FWC), and psychological well-being were examined in two longitudinal studies with full two-wave panel designs. In Study 1 ( n = 365), the time lag was one year, and in Study 2 ( n = 153), six years. The Structural Equation Modeling showed that the stability for WFC was .69 over one and .73 over six years. The respective stabilities for FWC were .57 and .48. Cross-lagged relations were not detected between WFC/FWC and low psychological well-being (job exhaustion, marital adjustment, parental stress, and psychological distress), expected to exist on the basis of the i…
The role of career values for work engagement during the transition to working life
2013
Abstract The present longitudinal study examined the role of career values for work engagement across the transition from university education to working life. Finnish young adults reported on their career values (intrinsic, rewards, and security values) at the age of 23; and the degree of person–organization fit (value congruence, and congruence between one's education and the job), subjective income and economic stress two years later at the age of 25. Work engagement was assessed at both measurement points. Structural equation modeling results showed, first, that intrinsic but not rewards or security career values were related to work engagement. Second, value congruence and having a job…
Organizational justice and extrarole customer service: The mediating role of well-being at work
2008
The purpose of this article is to propose and test a model of extrarole customer service (ERCS). We propose that organizational justice (distributive, procedural, interpersonal, and informational) promotes well-being at work (low burnout and high engagement). Well-being at work, in turn, engenders more effective ERCS. Thus, well-being at work is considered a mediator of the relationships from organizational justice to ERCS. This fully mediated model was compared to an alternative fully direct model. The sample consisted of 317 contact employees who were working in the Spanish service sector. The results of structural equation modelling supported the importance of the mediating role of the p…
Micro-Level Mechanisms to Support Value Co-Creation for Design of Digital Services
2023
This study identifies micro-level value co-creation mechanisms that support the design of digital services. As services are now becoming digital—or at least digitally enabled—how to design digital services that enable value co-creation between a service provider and customers has become an increasingly important question. Our qualitative research study provides one answer to this question. Based on 113 in-depth laddering interviews analyzed using interpretive structural modeling, our study shows that value co-creation mechanisms differ between business-to-business and customer-to-customer digital service types. We identify five mechanisms to support value co-creation in the design of digit…
Stability and change model of job resources and work engagement: A seven-year three-wave follow-up study
2015
Using the stability and change model, conservation of resources theory and the job demands-resources model, this study aimed to determine: (1) the extent to which work engagement and job resources can be explained by a component reflecting stability and a component reflecting change in these constructs, and (2) the strength and direction of the relationship between work engagement and job resources when their stable components are controlled for. The study was carried out among 1,964 Finnish dentists over a seven-year time period (2003–2010), using a three-wave dataset. Some of the dentists had changed jobs during the follow-up, and therefore the research questions were validated among grou…
Victimization, loneliness, overt and relational violence at the school from a gender perspective
2015
This ex post facto study analyzes both the direct relationships between victimization and overt and relational violent behavior of students adolescents as the indirect relationships between these variables through the classroom environment, the loneliness, the nonconformist ideal reputation and transgression of social norms. The sample consisted of 1,795 adolescents (48% females) aged 11 to 18 years (M = 14.2, SD = 1.68). We used a structural equation model to analyze the effect of classroom environment and victimization in violent manifest and relational behavior. The results found that a direct positive relationship between victimization and relational violent behavior and a direct negati…
Rates of tooth movement and bone remodeling activity : self-ligating versus conventional brackets
2019
Background Bracket systems have been developed with the purpose of reducing frictional resistance between the archwire and accessories. The aim of this research was to compare rates of tooth movement and regions of cellular bone modeling activity along tooth root surfaces of teeth moved with conventional vs. self-ligating brackets. Material and Methods The experiments were conducted in 20 male dogs. Bands were cemented in all intermediate incisors, with conventional brackets (Morelli) on the right side and hybrid self-ligating ones (T3-American Orthodontics) on the left side. A 0.019” x 0.025” stainless steel wire was inserted passively in the slot of these brackets with chain elastics (250…
Statistical characterization of self-assembled charged nanoparticle structures
2013
We propose a novel approach for description of dynamics of nanostructure formation for a system consisting of oppositely charged particles. The combination of numerical solution of analytical Bogolyubov–Born–Green–Kirkwood–Yvon (BBGKY) type equation set with reverse Monte Carlo (RMC) method allows us to overcome difficulties of standard approaches, such as kinetic Monte Carlo or Molecular Dynamics, to describe effects of long-range Coulomb interactions. Moreover, this allows one to study the system dynamics on realistic time and length scales. We applied this method to a simple short-range Lenard–Jones (LJ)-like three- (3D) and two-dimensional (2D) system combining the long-range Coulomb an…
Recent Advances in Static Output-Feedback Controller Design with Applications to Vibration Control of Large Structures
2014
Published version of an article in the journal: Modeling, Identification and Control. Also available from the publisher at: http://dx.doi.org/10.4173/mic.2014.3.4 Open Access In this paper, we present a novel two-step strategy for static output-feedback controller design. In the first step, an optimal state-feedback controller is obtained by means of a linear matrix inequality (LMI) formulation. In the second step, a transformation of the LMI variables is used to derive a suitable LMI formulation for the static output-feedback controller. This design strategy can be applied to a wide range of practical problems, including vibration control of large structures, control of oshore wind turbine…
Discovery of the 3-Amino-1,2,4-triazine-Based Library as Selective PDK1 Inhibitors with Therapeutic Potential in Highly Aggressive Pancreatic Ductal …
2023
Pyruvate dehydrogenase kinases (PDKs) are serine/threonine kinases, that are directly involved in altered cancer cell metabolism, resulting in cancer aggressiveness and resistance. Dichloroacetic acid (DCA) is the first PDK inhibitor that has entered phase II clinical; however, several side effects associated with weak anticancer activity and excessive drug dose (100 mg/kg) have led to its limitation in clinical application. Building upon a molecular hybridization approach, a small library of 3-amino-1,2,4-triazine derivatives has been designed, synthesized, and characterized for their PDK inhibitory activity using in silico, in vitro, and in vivo assays. Biochemical screenings showed that …
