Decentralization has profound implications for many health systems. This study investigates the effect of health system decentralization in Organization for Economic Co-operation and Development (OECD) countries on public health security capacity and health service satisfaction.

Multiple linear regression analyses were employed for variables related to the level of health security capacity and satisfaction with the healthcare system while controlling for all socio-demographic variables from the European Social Survey, including over 44,000 respondents from 25 OECD countries. The Health Systems in Transition series of countries were used for assessing the decentralization level.

The result of multiple linear regression analyses showed that the level of decentralization in health systems was significantly associated with higher health security capacity (ß-coefficient 3.722, 95% confidence interval (CI) [3.536 3.908]; p=<0.001) and health service satisfaction (ß-coefficient 1.463, 95% CI [1.389 1.536]; p=<0.001) in the study. Countries with a higher level of decentralization in health policy tasks and areas were significantly likely to have higher health services satisfaction, whereas this satisfaction had a significant negative relation with the lower level of decentralization status of secondary/tertiary care services in OECD countries (ß-coefficient −5.250, 95% CI [−5.757–4.743]; p = 0.001).

This study contributes to a better understanding of the extent to which decentralization of health services affects public health safety capacity and satisfaction with health services, whereas the level of decentralization in OECD countries varies considerably. Overall, the findings highlight the importance of public health security and satisfaction with health care delivery in assessing the effects of decentralization in health services.

The purpose of this paper is twofold. First, it aims to analyze the individual influence of different knowledge management practises (KMP) on firm performance. Second, it aims to analyze the mediating role of organizational learning (OL) between each KMP and performance.

A telephone-survey was applied in 2018 to the managers of 400 Spanish firms. The data retrieved was analyzed by using multiple regression analysis.

Knowledge generation (KG) and knowledge flow (KF) promote firm performance, while there is not a direct association between knowledge storage and performance. OL mediates the relationship between KG and performance, as well as between KF and performance.

First, this research confirms that not all the KMP have a direct effect on firm performance, thus, future research would need to differentiate between different KMP. Second, this paper is pioneering in providing empirical evidence that OL mediates the KMP – performance relationship. Third, the empirical study was performed in a context non-researched yet by the literature considering KMP individually: Spain.

First, besides the results managers should focus their efforts in practises related to KG and application. Second, OL mediating suggests that managers should invest in managerial commitment to promote a shared culture, shared vision, open-mind to new ideas and a lot of dialogue.

This is the first study that investigates how KMP contribute to firm performance by incorporating the mediating impact of OL. The results will help organizations to identify the KMP improving the performance.

The purpose of this paper is to study the fertility potential of the iron- and steel-making process waste granulated blast furnace slag to recover it as a beneficial product.

This slag fertilizer was mixed with organic fertilizer to enrich and dung the vegetable sets are pepper, lettuce and cucumbers.

In this study, 100 per cent granulated slag, 75 per cent granulated slag + 25 per cent fermented manure, 50 per cent granulated slag + 50 per cent fermented manure and 25 per cent granulated slag + 75 per cent fermented manure compositions were mixed with water and added to seeding pots. The growth rate of vegetable sets and also the level of contamination of heavy metals such as lead, copper, aluminum, mercury and cadmium were analyzed. The analyses results showed that contamination rates of lead, copper, aluminum, mercury and cadmium in lettuce and cucumber samples were in the range of acceptable levels for human health. Slag fertilizer enforced the set of growth rate and productivity, too.

By the recovery of the waste slag storage, transport and annihilation economical load on the industry would be eliminated, waste recovery contributes to the economical gaining and beneficial recovered products replace the need of fertility products.

Blended wing body (BWB) is a very advantageous design in terms of low fuel consumption, low emission and low noise levels. Because of these advantages, the BWB is a candidate to become the commercial passenger aircraft of the future by providing a paradigm shift in conventional designs. This paper aims to propose a key design parameter for wing sizing of subsonic BWB and a performance parameter for calculating the lift/drag ratio values of BWBs.

The parameter proposed in the study is based on the square/cube law, that is, the idea that the wetted area is proportional to the power of 2/3 of the weight. Data on the weight, wing area, wingspan, lift-to-drag (L/D) ratio for 19 BWB used in the analyzes were compiled from the published literature and a theoretical methodology was developed to estimate the maximum lift to drag ratio of BWBs. The accuracy of the proposed key design parameter was questioned by comparing the estimated L/Dmax values with the actual values.

In the current study, it is claimed that the wingspan/(take-off gross weight)^(1/3) parameter provides an L/D efficiency coefficient regardless of aircraft size. The proposed key design parameter is useful both for small-scale BWB, that is unmanned aerial vehicles BWB and for large-scale BWB designs. Therefore, the b/Wg^(1/3) parameter offers a dimensionless L/D efficiency coefficient for BWB designs of different scales. The wetted aspect ratio explains how low aspect ratio (AR)-BWB designs can compete with high AR-tube-and-wing designs. The key parameter is also useful for getting an idea of good or bad BWB with design and performance data published in the literature. As a result, reducing the blending area and designing a smaller central body are typical features of aerodynamically efficient BWB.

As the role of the square/cube law in the conceptual aircraft design stage has not been sufficiently studied in the literature, the application of this law to BWBs, a new generation of designs, makes the study original. Estimation of the wetted area ratio using only wingspan and gross weight data is an alternative and practical method for assessing the aerodynamic performance of the BWB. According to the model proposed in the current study, reducing the take-off gross weight of the BWBs using lighter building materials and designing with a larger wingspan (b) are the main recommendations for an aerodynamically efficient BWB.

The purpose of this study was to expand available knowledge on predictors of male inmate violence by examining a large set of variables offered by the importation, deprivation and threat appraisal and coping theories.

A total of 465 male inmates from five medium-security prisons in Wisconsin completed surveys to report demographics, violence, personality, social stressors and healthy coping behaviors to help manage risk by identifying key factors.

Inmates reported more violence with the “imported” characteristics of younger age, less incarceration, no college experience and personality patterns of impulsiveness, hostility and internal locus of control. More violence was reported by inmates with social stressors experienced from family and correctional staff. Additionally, less violence was reported by inmates with more healthy coping behaviors of exercise and social support, especially from family and other inmates.

One must remain uncertain about whether similar patterns of demographics, personality, social stressors and coping behaviors associated with inmate violence would be found in other US prisons. Future research can determine whether similar predictors of violence are found for women inmates and the consideration of ethnicity should be warranted when examining predictors of inmate violence.

Prison administrators can develop new programs to reduce social stressors and increase healthy coping behaviors found by this study to be significantly associated with reduced violence, exercise and social support from other inmates and family.

This research recommends that educating and training correctional staff for a trauma-informed care approach is an integral part of lessening the effects of “pains of imprisonment” on inmate violence and healing the effects of trauma.

To the best of the authors’ knowledge, this study provides the first direct comparison of social stressors from other inmates, correctional staff or family members outside the prison as possible predictors of male inmate violence.

The purpose of the study is to highlight the effect of human resources information systems (HRISs) implementation success on the job involvement, job satisfaction and work engagement of the employees in small and medium enterprises (SMEs).

Following an investigative study, a quantitative research is done with a positivist approach. A sample of 1,082 responses from 163 SMEs in different economic sectors is analyzed using statistical package for social sciences and structural equation modelling.

The results show that HRIS successful implementation explains the variation in job involvement and work engagement to a limited extent while it does highly affect employees’ job satisfaction. Moreover, the correlation between job involvement and both HRIS implementation success and job satisfaction is negative.

The researchers were not able to conduct intersector analysis for differences among economic sectors. Existing gender differences in job involvement, work engagement and job satisfaction are hinted to and need further analysis.

The HRIS users with higher educational background tend to display a more open approach toward using the system and seeing the system’s implementation succeed. Tenured managers display low enthusiasm toward HRIS success, although being highly involved and engaged in the SME’s life. This provides for not only a steady work-flow but also fosters resistance to change. The successful implementation of the HRIS is a new dimension in the hands of managers at work, facilitating their supervisor work routines and affecting employees’ satisfaction, involvement and engagement.

The HRIS success allows more flexibility at the supervisor level of daily work, opening a window toward flexible working hours and indirect supervision. It allows users some freedom and flexibility and the application of their own ethical beliefs when self-reporting.

Although most research looks at corporations and the factors leading to HRIS implementation success, this study goes beyond the implementation to dwell into Small and Medium Enterprises (SMEs), looking at HRIS after its implementation success, as a potential tool for motivating, involving and engaging employees.

This article aims to explore the connections between tacit knowledge management and the capacity to create new products and services for stimulating organizational performance.

This research utilizes a questionnaire-based study and 378 questionnaires gathered from different provinces of China between August and October 2022. The SmartPLS technique was used to evaluate the regression and mediation analysis on lower-order and higher-order components of the research hypotheses behind the model.

This investigation's results indicate that the tacit knowledge management process (TKMP) significantly drives product and service innovation and impacts organizational performance (ORP). According to the results, TKMP did not directly influence ORP and product innovation to mediate between Tacit knowledge and organizational performance.

Future research should concentrate on different combinations of influences on innovation and other consequences of introducing innovation into businesses. Moreover, researchers may add moderators to innovation and organizational performance.

This study assists managers in how tacit knowledge management affects organisational performance by examining product/service innovation capabilities. Product innovation also mediates between tacit knowledge and organizational performance. Service innovation improves organizational performance, prioritizing knowledge creation, sharing and retention to increase innovation and organizational success.

This study contributes to the literature on tacit knowledge management, innovation capability and organizational performance by concentrating on the tacit knowledge process and using the resource-based view. This study gives a solid theoretical and practical basis for understanding the component interactions.

This study aims to investigate the working way of the e-Pulse portal in Türkiye as a sample of a next-generation digital tool for health data management. Accordingly, this study focuses on explaining the structure and key services of the e-Pulse portal in the context of health data management.

This study is a technical paper that will explain how the e-Pulse portal works in Türkiye. Accordingly, the data are based on secondary sources and mostly the official website of the e-Pulse portal. As a sample case, this study investigates the e-Pulse portal from Türkiye. The data are categorized by tables, and some key factors are classified based on review results.

As a result of the review of the e-Pulse portal's sample account, it is seen that the e-Pulse portal provides comprehensive data for personal health data for both individuals and healthcare professionals. By permitting healthcare professionals, users or patients can share their personal health data on specific dates and numbers whenever they need and want. When sharing recorded personal health data, citizens or patients can get more efficient healthcare service on the time.

By giving descriptive evidence and review through the e-Pulse portal, countries with high-populated can see the key e-services and elements to manage health data through digital tools. On the other side, this study has some limitations. This study investigated the e-Pulse portal and its e-services for Türkiye and gave some findings mostly based on subjective deduction. Another digital portal can give different findings for the literature.

Based on the e-Pulse portal case, it is determined that by creating a digital portal with recorded personal up-to-date health data, healthcare services can be ensured more efficiently among high-populated countries in the long term. While population growth and pandemic possibilities such as COVID-19 increase throughout the world, serving more patients with these portals will increase efficiency and service quality, provided that patient information is well protected.

This study reveals key e-services and segments to provide personal health data management by a next-generation digital tool based on the e-Pulse portal. The main contribution of this study is expected to guide other countries when adapting next-generation technology or systems to manage health data in the future.

The purpose of this study is to investigate the microstructure of fretting wear behavior in 6061-T6 aluminum alloy. The fretting wear of blind riveted lap joints of 6061-T6 aluminum alloy plates, which are widely used in aircraft construction, was investigated. Fretting damages were investigated between the contact surface of the plates and between the plate and the rivet contact surface.

Experiments were carried out using a computer controlled Instron testing machine with 200 kN static and 100 kN dynamic load capacity. Max package computer program was used for the control of the experiments. Fretting scars, width of wear scars, microstructure was investigated by metallographic techniques and scanning electron microscopy.

It was found that fretting damages were occurred between the plates contacting surface and between the plate and rivet contact surface. As load and cycles increased, fretting scars increased. Fretting wear initially begins with metal-to-metal contact. Then, the formed metallic wear particles are hardened by oxidation. These hard particles spread between surfaces, causing three-body fretting wear. Fretting wear surface width increases with increasing load and number of cycles.

The useful life of many tribological joints is limited by wear or deterioration of the fretting components due to fretting by oscillating relative displacements of the friction surfaces. Such displacements are caused by vibrations, reciprocating motion, periodic bending or twisting of the mating component, etc. Fretting also tangibly reduces the surface layer quality and produces increased surface roughness, micropits, subsurface microphone.

This study aims to explore the risk level of pufferfish and lionfish by comparing them among Turkish marines. In addition, this study focuses on comparing pufferfish with lionfish to determine which one is more dangerous for marine economics in Türkiye.

This study employs descriptive content analysis to give some qualitative evidence for the related literature. As a sample case, Türkiye was selected in the context of being a country in the Mediterranean Basin. By reviewing recent news, reports and publications, this study firstly will conclude how invasive alien marine species affect Turkish marines. Then, pufferfish and lionfish will be compared together to determine the risk level of these species for Turkish marine economics.

As a result of descriptive findings, it is seen that captured fishery has been declined in Turkey recently due to many factors including climate change, global warming, overfishing, environmental pollution and attack of invasive alien species. Pufferfish and lionfish are seen as the most spread marine species in Turkish marines. When comparing pufferfish with lionfish, it is seen that pufferfish is more dangerous than lionfish for Turkish marine economics.

This study provides descriptive and original findings as a result of comparison of pufferfish and lionfish due to their impact on Turkish marine economy. It is thought to give useful importation for the fight against invasive alien marine species in the Mediterranean Basin. Future studies can investigate different invasive alien marine species and their impacts on marine economics in the Mediterranean Basin.

Based on the Turkish cases, it is determined that there should be different policies for fight against invasive alien marine species in the Mediterranean Sea. Each marine species has different impacts on seafood market. Some of marine species can be consumed as a seafood product but some of them can't be consumed that policy makers should develop other strategies such as catching them to reduce their population in the local marines.

The spread of invasive alien marine species is still continuing in the Mediterranean Basin. Each country has been affected by the attack of invasive alien marine species. To keep sustainable seafood market and marine economics, countries should both implement common policies and develop policies specific to threats in their own countries.

This study reveals key points in the rise of invasive alien marine species in Turkish marines at first. The main contribution of this study is to be a recent sample for a country which is under attack by invasive alien marine species by giving a comparison of pufferfish and lionfish.
