Automating the processing of videos in applications such as surveillance, sport commentary and activity detection, human-machine interaction, and health/disability care is crucial to their correct functioning. In such video processing tasks, recognition of various human actions is a pivotal component for the correct understanding of videos and making decisions upon it. Accurately recognizing human actions is a complex process, demanding high computing capabilities and intelligent algorithms. Several factors, such as object occlusion, camera movement, and background clutter, further challenge the task and its accuracy, essentially leaving deep learning approaches the only viable option for properly detecting human actions in videos. In this study, we propose CoReHAR, a novel Human Action Recognition method that employs both deep Convolutional and Recurrent neural networks on raw video frames. Using the pre-trained ResNet152 CNN, deep features are initially extracted from video frames. The sequential information of the frames is then learned using DB-LSTM RNN. Multiple stacked layers in forward and backward passes of the DB-LSTM provide increased network depth for higher accuracy. A number of techniques are also applied to improve CoReHAR’s processing speed on heterogeneous GPU-enabled systems. The proposed method is evaluated using PyTorch, and is compared to the state-of-the-art methods, showing a considerable efficiency increase, with nearly 95% recognition accuracy measured as an average over all splits of the challenging UCF101 dataset.

Today, we confront forces bringing spiritual and ethical values into business which have together has a meaningful concept for each business. Nowadays, the growing attention to ethical issues in workplaces has caused the organizations tend to set ethical codes. However, the results of recent studies show that the ethical organizations will obtain more benefits over a long period and will gain better financial and non-financial performance. So this issue has caused the ethical values of organization be an important part of the organization’s culture. Beside this, ethical issues have always been a noteworthy topic in tourism concepts. Therefore, the present research has examined the effect of ethical values and empathy on nonfinancial performance of tour operators in Tehran through the organizational commitment. The statistical population is composed of employees of tour operators and data were collected by the standard questionnaires. Results show that ethical values and empathy in workplace have a positive and significant effect on organizational commitment and following that non-financial performance of organization.

Recreation and entertainment are among the major objectives and intentions of tourism. The reasons put forward by tourists include escaping quotidian life and social interactions. Relying on the Muslim mystics’ view of the real nature of human being, this article offers an analysis of escaping quotidian life and environment in the discovery of real identity and studies the role of traveling in this regard. This analysis showed that from the Muslim mystics’ viewpoint, the real nature of humans is impoverishment and desperate need for a raison d’etre. Meantime, social interactions and affiliation with minor and major social groups overshadow such identity and create obstacles in the way of self-awareness. That explains why the disciples of Islamic Sufism were recommended retreatment. Even today, traveling and tourism provide such an opportunity for humans to distance themselves from the social groups and classes they belong to for some time and gain spiritual experience through a more precise perception of their own reality

While categorization of human beings into various subgroups in terms of their race, ethnicity, gender, religion, nationality and alike is not a new phenomenon but such a diversity in communities all around the world has drawn much attention to the issue in recent years due to the increasing importance of equality for governments and societies. Workplaces are among those contexts which are proposed to equality issues and are trying to deal with it utilizing different approaches among which creating spirituality in workplace is a noteworthy one. Tourism businesses are not an exception in this regard and are faced with the diversity challenge especially in terms of interaction between different cultures throughout the industry. Additionally, it seems that organizational outcome is influenced by level of diversity at the workplace. Therefore, this paper adopts a developmental descriptive-analytical approach implemented by documentary analysis to discuss the relationship between diversity management and organizational outcome and provides a theoretical model indicating how workplace spirituality (WPS) mediates the relationship between cultural diversity management and organizational outcome in tourism businesses since cultural diversity is as necessary for humankind as biodiversity is for nature and can be a source of competitive advantage for businesses as well.
