Teacher ability evaluation and changes in elementary student profiles of motivation and performance in mathematics
2018
Abstract The aim of this person-centered study is to identify the profiles of interest value, self-concept, and performance in the domain of mathematics among elementary school students and to examine the stability and changes in these profiles from grade 1 to grade 2. Teacher-reported evaluations of students' mathematical ability and gender were examined as predictors of changes in the student profiles. The sample consisted of 237 students (46.8% girls). The latent profile analysis identified four profiles: 1) low levels of interest value, medium levels of self-concept and performance; 2) low levels of interest value, self-concept and performance; 3) high levels of interest value, self-con…
Simulated raindrop's characteristic measurements. A new approach of image processing tested under laboratory rainfall simulation
2018
Abstract The size of the drops determines soil erosion and runoff rates, and then the fate of ecosystems. Various raindrop measurement techniques and tools have been developed to determine natural and simulated raindrop size distributions and mean drop size. There is a need to improve the procedure to determine the raindrop properties, and this is why we develop a new technique to analyze drop size distribution and fall velocity. For this purpose a rainfall simulator with two oscillating Veejet 80100 nozzles in laboratory condition, and high speed imaging technique and edge detection approach in image processing was applied to identify and measure drop size and calculate drop velocity. The …
Managerial Ability, Players’ Cultural Diversity, and Sporting and Economic Performance in English Soccer
2012
We use a large homemade database on professional soccer in England to estimate the relevance of managerial ability on performance and the managerial skills in keeping up cultural diversity. The team manager faces a set of very complex tasks. Not only he is the head coach of the soccer team, thus influencing sporting performance, but he can also have an impact on performance, by improving economic efficiency or by limiting the organization innovation in order to foster the creation of organizational routines. The sporting competitive advantage translates into economic and financial performance; therefore the manager is a dominant voice in the financial viability of the club, too. We also mea…
Strategic Responses: A Survey Experiment on Opposition to Pension Reforms*
2013
The responses given in opinion polls on future policy reforms reflect both subjective expectations and preferences. We disentangle these factors using data from a controlled survey experiment conducted in Germany. At the time of the experiment, an increased retirement age had been proposed as part of a pension reform. Thus, the survey respondents faced an incentive to give biased responses. By understating their expected work ability at the age of retirement, they could make the increase of the retirement age a less attractive policy option. We find evidence for such strategic response behavior, and this strategic bias appears to be stronger in former communist East Germany.
Unawareness and Partitional Information Structures
1999
Abstract We claim first that simple uncertainty is not an adequate model of a subject's ignorance, because a major component of it is the inability to give a complete description of the states of the world, and we provide a formal model of unawareness. In Modica and Rustichini (1994) we showed a difficulty in the project, namely that without weakening of the inference rules of the logic one would face the unpleasant alternative between full awareness and full unawareness. In this paper we study a logical system where non full awareness is possible, and prove that a satisfactory solution to the problem can be found by introducing limited reasoning ability of the subject. A determination theo…
Self-care ability of older people living in urban areas of northwestern iran
2018
Background: Self-care ability was considered as a mechanism to improve the quality of life and reducing the high costs of medical services for elder people. Iran is experiencing increased elder people and healthy aging is one of the challenges. This study aimed to investigate self-care ability of elder people in Shahid Chamran and Dr. Shadpour health complexes, Tabriz- Iran. Methods: This was a cross-sectional study done in 2015. “The Self-care Ability Scale for the Elderly (SASE)” valid and reliable questionnaire (Persian version) was used for data collection. Totally, 220 samples were selected using G-Power 3.1.5 software. Sampling was conducted through systematic random method. Data were…
Comparison of three adhesive systems in class II composite restorations in endodontically treated teeth : influence of Er:YAG laser conditioning and …
2018
Background Dental surface conditioning by Er:YAG laser is currently being investigated, as not all of the mechanisms and effects of this technique have been clearly studied. Thus, the aim of the present study was to assess the cervical microleakage of Class II resin composite restorations in endodontically treated teeth following either the respective conventional conditioning or additional Er:YAG laser conditioning, in association with varied adhesives. Material and methods Standardized mesial-occlusal-distal cavities (two gingival walls positioned in dentin and enamel, respectively) were created in 60 extracted human premolar teeth. Following the completion of the endodontic therapy, the …

A cross-country study of skills and unemployment flows
2021
AbstractUsing an international survey that directly assesses the cognitive skills of the adult population, I study the relation between skills and unemployment flows across 37 countries. Depending on the specifically assessed domain, I document that skills have an unconditional correlation with the log-risk-ratio of exiting to entering unemployment of 0.65–0.68 across the advanced and skill-abundant countries in the sample. The relation is remarkably robust and it is unlikely to be due to reverse causality. I do not find evidence that this positive relation extends to the seven relatively less advanced and less skill-abundant countries in the sample: Peru, Ecuador, Indonesia, Mexico, Chile,…
EXPLORATION OF HEALTHY AGEING DETERMINANTS IN BALTIC STATES
2021
According to the WHO, healthy ageing is characterized by such interrelated determinants as intrinsic capacity, functional ability and environment. An individual's intrinsic capacity is a powerful predictor of the future ageing process and includes 5 areas - cognitive, psychological, sensory, locomotion and vitality. Exploration of these areas can provide necessary information for therapeutic and preventive actions that can be tailored to an individual's needs, priorities and values to support participation and quality of life. The objective of this study was to evaluate and compare healthy ageing determinants of older individuals in the Baltic States. The research was based on the sample of…
