The aim of the study is to emphasize the importance of organizational learning capacity (OLC) and to measure its influence on organizational effectiveness (OE) in metalworking manufacturing.

The research plan has been stated as; looking for the survey questions in the literature, reaching the participants, informing them about the survey, gathering the data, and measuring and analyzing the data. The survey instrument has been applied on metal industry employees in Turkey. The valid responses have reached to 578. We analyzed the data by SPSS (Statistical Package for the Social Sciences) version 11.5.

There are significant correlations (at the 0.000 level) between OE and all OLC dimensions (systems orientation, organizational climate for learning orientation, knowledge acquisition and utilization orientation, and information sharing and dissemination orientation). The total explained variance of OE (depending on OLC) has been calculated as 65 percent.

We have calculated the OE value in terms of employee satisfaction, customer orientation and financial and growth performance, whereas there may be other factors to be considered for the related value.

The organizations should consider knowledge‐intensive activities more precisely when constructing their strategic maps.

This study helps to fulfill the gap between the OE and OLC from a managerial point of view in metalworking manufacturing. The main audiences are global businesses as well as academic researchers.

The main purpose of this study is to make a comparative evaluation of the impacts of previous outbreaks and coronavirus disease 2019 (COVID-19) on the tourism industry. COVID-19 appears to have disrupted all memorizations about epidemics ever seen. Nobody has anticipated that the outbreak in late December will spread rapidly across the world, be fatal and turn the world economy upside down. Severe acute respiratory syndrome, Ebola, Middle East respiratory syndrome and others caused limited losses in a limited geography, thus similar behaviors were expected at first in COVID-19. But it was not so. Today, people continue to lose their lives and experience economic difficulties. One of the most important distressed industries is undoubtedly tourism.

This study is a literature review. In this review, a comparative evaluation between the impact of previous outbreaks and COVID-19 on the tourism industry has been made based on statistics and previous research studies.

The information and figures obtained show that COVID-19 and previous outbreaks have such significant differences that cannot be compared. COVID-19 has been one of the worst to live in terms of spreading speed, the geography where it spreads, loss of lives and negative effects in the whole area.

It is noteworthy that COVID-19 is very severe in terms of death cases and also its impacts on the economy compared to other pandemics. It remains to be argued that COVID-19 can also be a reference in terms of possible new outbreaks in the future, and is an effective actor in determining future strategies.

During the past several years, research and studies in the field of solar energy have been continuously increased. One of the substantial applications of solar energy is related to industrial utilization for the drying process by efficient heat transfer methods. This study aims to upgrade the overall performance of an indirect solar dryer using a solar absorber extension tube (SET) equipped with ball-type turbulators.

In this work, three various SETs including hollow (SET Type 1), 6-balls (SET Type 2) and 10-balls (SET Type 3), have been simulated using Fluent software to evaluate heat transfer characteristics and flow structure along the air passage. Then, the modified solar drying system has been manufactured and tested at different configurations.

The findings indicated that adding a SET improved the performance notably. According to the results, using turbulators in the tube has a positive effect on heat transfer. The highest overall thermal efficiency was found in the range of 51.47%–64.71% for the system with SET Type 3. The maximum efficiency increment of the system was found as 19% with the use of SET. Also, the average specific moisture extraction rate, which is a significant factor to survey the effectiveness of the dehumidification system was found between 0.20 and 0.38 kg kWh⁻¹.

In the present study, a novel SET has been developed to upgrade the performance of the solar dehumidifier. This new approach makes it possible to improve both thermal and drying performances.

Over the recent years, solar energy has received outstanding attention from researchers. Solar energy applications and related large-scale projects are increasing to meet growing global energy demand as an economical, non-polluting and renewable energy source. The purpose of this study is investigating different plenum and absorber configurations of solar air heating wall (SAHW) experimentally and numerically.

In this study, various configurations of SAHW have been numerically simulated to determine the most effective design. According to the simulation results, two SAHWs with various plenum thicknesses have been fabricated and tested at different conditions.

Numerical simulation results indicated that parallel-flow SAHWs exhibited better performance in comparison with other placements of absorber plate. Regarding to the experimentally attained results, the highest thermal efficiency was reached to 80.51%. Also, the average deviation between experimentally and numerically obtained outlet temperature is 5.5%.

Considering the obtained results in the present study, designed SAHW has admissible efficiency to be used in various industrial and residential applications such as; air preheating, space heating and drying.

Innovation is the basic input to organizational endurance; therefore, the study of processes that support innovation should be of interest to practitioners and researchers alike. Consequently, there is increasing attention for the supplementary research examination of the influencing elements of innovativeness.

The data were collected in 2018 using adapted questionnaires that were tested. The respondents were 446 employees of Pakistan Electric Power Company (PEPCO). Bivariate correlations and hierarchical regression were used for the data analysis.

The findings showed that the competing value framework (CVF) model of organizational culture may promote innovativeness that translates to the progress of PEPCO, which deserved barrier for everyone relying on the values made by the culture of the organization. The adhocracy culture is considered to be statistically suitable for the prediction of performance and enhancement of innovation in the organization. Based on the above findings, it may be deduced that innovation mediated the relationship between some particular types of organizational culture and performance.

The CVF model provides a supportive framework for the development of procedures that promote innovation in the organization. The focus of the CVF model highlighted employees' behavior and function of organizational culture, which can restrain or stimulate performance. This study reported and developed a basis for an empirical model based on the CVF model.

This paper found that the CVF model and innovation are mega sources of innovation at PEPCO. This work should be of interest in the area of innovation and performance improvement. There are very few empirical research studies on the relationship between organizational culture, innovation and performance, specifically in the context of developing countries. This is one of the very few studies conducted to empirically examine the influence of CVF model on performance through the mediating role of innovation in PEPCO.

The study aims to examine the mediating effects of escapism (ESC) and ethnic food experience (EFE) in the relationship between diversity (DIV) and behavioral intentions (BI) of visitors attending Hoi An International Food Festival held in Vietnam.

The research takes a predictive and explanatory approach rather than theory confirmation. Partial least squares (PLS) algorithm was used to analyze multiple mediation. The data were collected from 323 attendees through a self-administered questionnaire.

The research highlights that escapism and EFE have positive and significant mediating effects on the relationship between DIV and BI. Furthermore, while EFE is the most important predictor of BI, escapism has emerged as an antecedent variable that deserves to be given the highest importance. Finally, visitors who are participating in their first international food festival do not seem to consider the nexus between DIV and ESC as much as repeaters.

The study's limitations include the collection of data from a single festival and the fact that the analyses are only quantitative. The results contribute to festival organizers by revealing the importance of multiple mediation roles.

This study contributes novel insights to the literature on festival and event management, extending previous studies and filling a gap by proposing ESC and EFE as multiple mediators in the nexus between DIV and BI. The present study provides a comprehensive examination of the influence of individual variables previously analyzed separately on festival-goers' experiences. This facilitated the identification of crucial aspects of the circumstance, thereby reducing any ambiguity.

The authors examined how the identification mechanism of the innovation performance of knowledge employees is affected by empowering leadership by influencing the organizational identification and the moderating effect of leaders on the role expectation of knowledge employees as an essential innovation subject.

The authors employed a mixed-method research approach. The authors collected data from 378 knowledge employees and managers in 20 companies in China's Yangtze River Delta cities. The authors analyzed data using multiple regression analysis forecasting methods.

The authors found that there was an inverted U-shaped relationship between empowering leadership and the innovation performance of knowledge employees; organizational identity played a partial mediating role between empowering leadership and the innovation performance of knowledge employees; role expectation of leaders on the innovation behavior of employees regulated the relationship between the organizational identity and innovation performance of knowledge employees.

This study extends the literature on empowering leadership and innovation performance. This study empirically examines the mediating effect of organizational identity between empowering leadership and innovation performance. In addition, this study empirically examines how empowered leaders' expected innovation level moderates the association between organizational identity and innovation performance.

The purpose of this study is to experimentally and numerically scrutinize the heat transfer enhancement in pool boiling and condensation by changing the hydrophilicity or hydrophobicity properties of the working fluid, i.e. by use of nanofluid solution.

For specifying the effects of nanoparticle concentration on heat transfer properties, two different nanofluid solutions (h-BN/DCM and SiO₂/DCM) at three different volumetric concentrations were prepared and tested under different heat flux conditions. Boiling curves, alterations in pressure with heat flux and heat transfer coefficients for both boiling and condensation processes were obtained and viscosity measurements were performed for dichloromethane (DCM) and each working fluid was prepared. In addition, a series of numerical simulations, via computational fluid dynamics approach, was performed for specifying the evaporation–condensation phenomena and temperature and velocity distributions.

Nanoparticle addition inside the base fluid increased the thermal characteristics of the base fluid significantly. For the experimental results of h-BN/DCM nanofluid, the increment rate in heat transfer coefficient for saturation boiling, after-saturation boiling and condensation processes was found as 27.59%, 14.44% and 15%, respectively.

The novelty of this comparison study is that there is no such experimental and numerical comparison study in literature for DCM fluid, which concentrates on thermal performance enhancement and compares the effect of different kinds of nanoparticles on heat transfer characteristics for boiling–condensation processes.
