This paper aims to explain that it is vital for any organization to imbue employee skills assessment before tailoring any training program and has further accelerated the genesis of the ‘Training-Chart' which is an indicator of both employee skills and organizational expectations .Exploratory research method is used for this study and Employability Skill Framework is developed using Factor analysis. The Employee skill set is further subjected to K-means cluster analysis where every cluster profile extracted represents the detailed summary of the employees in the cluster, in the context of their expertise in the present jobs. Based on these cluster profiles and their implications, 78 respondents have categorised the utility and essentiality of different skill segments on three different levels of organization. This paper is aimed to provide a holistic approach to make the training activities more effective.

Equipment System

Maintaining a high level of maintenance of electrical equipment in passenger cars requires research in the field of improving methods and means of technical diagnostics. Electronic devices for automatic control and protection, which are located in the switchboard of the car, are one of the most critical elements in the electrical equipment system, ensuring its reliable, efficient and safe operation. If the automatic adjustment and protection devices are out of regulation during operation, the voltage and current in the electrical equipment network may exceed the permissible level, which leads to the failure of electricity consumers, a battery and a generator. In addition, the semiconductor devices themselves are very sensitive to short-term overloads, in which, even with minor overloads, a breakdown or breakage of the conductive layer occurs. Modern trends in the development of passenger car fleet indicate a sharp increase in the complexity of the element base of cars. This mainly concerns the electrical systems of cars, where all the functions of control, monitoring and diagnostics are performed by electronics. Maintaining a high level of service for such systems requires research in the field of improving methods and means of technical diagnostics. For these purposes, the authors have developed a method for constructing optimal control and diagnostic tests, which is based on a combinatorial approach. The method is easily implemented on a computer.

Marginalized older adults are highly vulnerable to COVID-19 due to social isolation and physical and functional limitations. Despite these stressors, they appear to be resilient by leveraging individual, community, and societal resources. This study conducted in-depth interviews with marginalized older adults to understand how COVID-19 affected their mobility and daily lives. We also identified different levels of protective factors affecting their resiliency to pandemic stressors. COVID-19 influenced not only the physical health but also the mental health of older adults. However, they overcame adversity by using technology to continue daily activities, exchanging informal support with family and neighbors, relying on formal support from community organizations, and keeping themselves physically active in their neighborhoods. Our findings suggest a holistic approach to enhance the resilience of older adults during an unprecedented event.

Control Implementation

The article describes the general principles of supervisory control organization in extreme robotics scenarios with different levels of autonomy. It is shown that increasing the level of autonomy of the robot allows reducing the operator’s load due to the division of labor between man and machine and to the implementation of the supervisory control mode, the essence of which is the decomposition of the mission into scenarios, which describe algorithms for solving functionally completed tasks and consists of sequence of simple technological operations. Such scenarios are executed automatically. In this case, the operator mainly implements the functions of monitoring and diagnostics, and the control functions are reduced to making decisions about the execution of the next scenario or intervention into execution of the current scenario in cases when the robot makes an obvious mistake or encounters a problem that it cannot solve on its own. Examples of supervisory control implementation when performing work on critical infrastructure facilities, performing search and rescue and other special operations under challenging conditions, including those of heterogeneous groups of robots, are given.

The value chain of agri-food is radically changed due the fact that consumers, as well as various players in the agro-logistics chain, seek for increased and trustful food safety. Given the specific characteristics of the agri-food supply chain, having numerous origin points, several aggregations hubs at different levels and then again numerous points of sales, the need of a holistic approach in collecting, forwarding and interpreting data in an interoperable way is a dire need. In this chapter, the authors present the architecture of the traceability platform KalaΘosTM and its IoT management module called, GP CoreIoTTM. The KalaΘos infrastructure includes a network of sensors devices at farms, equipment, trucks, aggregation, processing, and logistics facilities, connected to a network of LoRa gateways. Its open architecture focuses on semantic and syntactic interoperability approaches for joint exploitation of data collected and managed by other systems with similar aims and scope.

In equipment monitoring and diagnostics, it is very important to distinguish between a sensor failure and a system failure. In this paper, we develop a comprehensive methodology based on a hybrid system of AI and statistical techniques. The methodology is designed for monitoring complex equipment systems, which validates the sensor data, associates a degree of validity with each measurement, isolates faulty sensors, estimates the actual values despite faulty measurements, and detects incipient sensor failures. The methodology consists of four steps: redundancy creation, state prediction, sensor measurement validation and fusion, and fault detection through residue change detection. Through these four steps we use the information that can be obtained by looking at: information from a sensor individually, information from the sensor as part of a group of sensors, and the immediate history of the process that is being monitored. The advantage of this methodology is that it can detect multiple sensor failures, both abrupt as well as incipient. It can also detect subtle sensor failures such as drift in calibration and degradation of the sensor. The four-step methodology is applied to data from a gas turbine power plant.

Two conflicting forces beset any attempts to fit responsibility for environmental matters into modern constitutional structures. On the one hand the political desire for less centralised government calls for devolution of power to regional or local authorities, so that responsibilities are divided and distributed between different levels of government. On the other, the fact that no aspect of the environment can be treated as if it were a separate compartment suggests that responsibilities should be integrated in one place, an approach supported by the increasing awareness that there is a need for environmental considerations to influence all areas of policy if the goal of sustainable development is to be achieved. Fitting responses to the conditions1 of a particular locality is an important element in successful environmental policy, but so is ensuring that a coherent and holistic approach is taken, unhindered by institutional divisions.2 The purpose of this paper is to examine how two structures of devolved administration, for the Autonomous Communities in Spain and for Scotland, meet the challenge of reconciling these opposite forces, and how the constitutional structures influence the way in which potential problems are resolved.

PurposeThis study provides insights on the perceptions of residents in destinations offering different tourism products at different levels of tourism development.Design/methodology/approachA total of 1,122 valid responses were gathered through surveys from the residents of three unique destinations, with different levels of tourism development. Non-parametric tests were performed since the data was gathered on an ordinal scale and not distributed normally.FindingsThe tourism perceptions of the residents formed a five-factor structure, namely “socioecological negative”, “socioeconomic positive”, “socioecological development (wellbeing)”, “negative perceptions of tourism” and “tendency to become visitor”. All dimensions except for “socioeconomic positive” differed significantly by destinations in terms of level of tourism development or type of tourism product offered.Research limitations/implicationsResidents' perceptions of tourism differ based on different tourism products and different levels of tourism development of destinations. The residents of the most mature destinations in terms of tourism development have the most negative perceptions of tourism.Originality/valueAlthough there are studies investigating how residents' perceptions differ based on the level of tourism development of destinations, this study, with its holistic approach, aims to provide insights on how residents' perceptions of tourism differ based on the tourism products offered by different destinations. The selected destinations differ from each other in both their level of tourism involvement and products they offer, hence the originality of the current study with its unique contribution to the related body of knowledge.
