Abstract
Purpose
This paper aims to test the inverse analysis, based on the standard least-square method, which will finally lead to find the appropriate parameters of modelling of the brain cooling process.
Design/methodology/approach
To test the presented in this paper method of inverse analysis the numerical simulations of the bioheat transfer process in the neonatal body were performed. To model the bioheat transfer the Pennes bioheat equation and the modified Fiala model were applied.
Findings
The performed tests of the inverse analysis proved that it is possible to estimate the proper parameters of the process using this tool, but always with the small mistake.
Research limitations/implications
The presented method still requires a lot of tests. The test with the data from real measurements can be very valuable.
Practical implications
The determination of the proper parameters of the bioheat transfer in the neonatal body can finally be used to perform the numerical simulations of the brain cooling process.
Social implications
The performance of the numerical simulations of the brain cooling process in the proper way can finally helps protect newborns’ health and life.
Originality/value
In the paper the attempt of the inverse analysis in order to determine the parameters of bioheat transfer in the newborn's body is made.

Abstract
Purpose
This study aims to investigate the human resources management of regional tourism organizations (RTOs) in Poland as a condition for organization effectiveness and presents a model of RTO operation in destination management organizations for improved effectiveness.
Design/methodology/approach
The study was of qualitative nature because of the scope of the examined features and analyses of RTO effectiveness (here in relation to human resources). The research involved the following stages: desk research of secondary sources, pilot diagnostic survey and diagnostic survey proper, qualitative and statistical analyses. First, an analysis of secondary sources regarding conditions of RTO operation effectiveness took place. Next, a questionnaire was used to collect empirical data from 137 respondents from the same 13 group types, in equal numbers from each organization in the entire population of 16 RTOs.
Findings
The research identified 197 organizational effectiveness variables, in four feature groups: the effectiveness of statutory and economic objectives, stakeholders’ benefits from cooperating with RTOs and general characteristics of RTO operation effectiveness. The findings suggest that the characteristics of RTO employees influence organizational effectiveness, especially from the perspective of the organization’s stakeholders. There is a need for strong support for RTO employee structures as a measure to raise organization effectiveness.
Practical implications
Specific human resources practices are identified for the effectiveness of non-enterprise organizations (employee character and structure) that constitute an essential component of the management system at regional and national levels. New directions for RTO operations are also proposed.
Originality/value
The study fills a substantial and identified knowledge gap in assessing organization effectiveness level against the quality characteristics of RTO human resources. The analysis allowed the creation of a multidimensional and universal model of RTO effectiveness investigation, which facilitates comparative analysis of organizations despite their strong diversity. It can be implemented in assessing the effectiveness of other non-enterprise organizations in the context of tourism.
