This study investigated why employees' cyberloafing behavior is affected by their coworkers' cyberloafing behavior. By integrating social learning theory and deterrence theory, the authors developed a model to explain the role of employees' perceived certainty of formal and informal sanctions in understanding the effect of coworkers' cyberloafing behavior on employees' cyberloafing behavior.

The authors conducted a survey that involved a two-stage data collection process (including 293 respondents) to test our developed model. Mplus 7.0 was used to analyze the data.

The results revealed that employees' cyberloafing was positively affected by their coworkers' cyberloafing both directly and indirectly. The indirect effect of coworkers' cyberloafing on employees' cyberloafing was mediated by the employees' perceived certainty of formal and informal sanctions on cyberloafing. Employees' perceived certainty of formal and informal sanctions were found to mediate the relationship both separately (each type of sanctions mediates the relationship individually) and in combination (the two types of sanctions form a serial mediation effect).

The study reveals an important mechanism – employees’ perceived certainty of formal and informal sanctions – that underlies the relationship between coworkers' cyberloafing and employees' cyberloafing, thus, contributing to the cyberloafing literature. It also demonstrates the importance of negative reinforcement (perceived sanctions) in the social learning process, which contributes to the literature on social learning theory because previous studies have primarily focused on the role of positive reinforcement. Lastly, the study reveals a positive relationship between employees' perceived certainty of formal sanctions and informal sanctions, which has important implications for deterrence theory.

Employees' personal Internet usage (PIU) has become increasingly common at work. It is important for both researchers and managers to understand how PIU affects employee creative performance. This study aims to examine what kind of PIU is likely to increase or decrease employee creative performance and why. The authors also examine a potential boundary condition for the effect of PIU on employee creative performance.

Based on conservation of resource (COR) theory and broaden and build theory, the authors investigated the impact of two types of PIU, namely within-task PIU and between-task PIU, on the creative performance of knowledge workers. The authors conducted a daily diary study and surveyed 107 knowledge workers in China over 10 consecutive working days (n = 1,070) to test the model.

The authors find that within-task PIU reduces knowledge workers' creative performance by decreasing the workers' positive emotion, whereas between-task PIU promotes the performance by increasing positive emotion. The above relationships become stronger when knowledge workers perceive a higher level of organisational support.

The authors' study makes theoretical contributions by advancing researchers' understanding of the situations in which PIU may decrease or increase employee creative performance. The findings are also useful for developing organisational policies to take advantage of the positive side of PIU whilst avoiding PIU's negative side.

Laser additive manufacturing (LAM) technology based on powder bed has been used to manufacture complex geometrical components. In this study, IN625 superalloys were fabricated by high-power fiber laser without cracks, bounding errors or porosity. Meanwhile, the objectives of this paper are to systemically investigate the microstructures, micro-hardness and the precipitated Laves phase of deposited-IN625 under different annealing temperatures.

The effects of annealing temperatures on the microstructure, micro-hardness and the precipitated Laves phase were studied by optical microscope (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive spectrometer (EDS), selected area electron diffraction (SAED), backscattered electron (BSE) imaging in the SEM and transmission electron microscopy (TEM), respectively. The thermal stability of the dendritic morphology about IN625 superalloys was investigated through annealing at temperatures range from 1,000°C to 1,200°C.

It is found that the microstructure of deposited-IN625 was typical dendrite structure. Besides, some Laves phase precipitated in the interdendritic region results in the segregation of niobium and molybdenum. The thermal stability indicate that the morphology of dendrite can be stable up to 1,000°C. With the annealing temperatures increasing from 1,000 to 1,200°C, the Laves phase partially dissolves into the γ-Ni matrix, and the morphology of the remaining Laves phase is changing from irregular shape to rod-like or block-like shape.

The heat treatment used on the IN625 superalloys is helpful for knowing the evolution of microstructures and precipitated phases thermal stability and mechanical properties.

Due to the different kinds of application conditions, the original microstructure of the IN625 superalloys fabricated by LAM may not be ideal. So exploring the influence of annealing treatment on IN625 superalloys can bring theory basis and guidance for actual production.

This study continues valuing the fabrication of IN625 by LAM. It shows the effect of annealing temperatures on the shape, size and distribution of Laves phase and the microstructures of deposited-IN625 superalloys.

Nature and occurrence of food-borne pathogens in raw and processed food products evolved greatly in the past few years due to new modes of transmission and resistance build-up against sundry micro-/macro-environmental conditions. Assurance of food health and safety thus gained immense importance, for which bio-sensing technology proved very promising in the detection and quantification of food-borne pathogens. Considering the importance, different studies have been performed, and different biosensors have been developed. This study aims to summarize the different biosensors used for the deduction of food-borne pathogens.

The present review highlights different biosensors developed apropos to food matrices, factors governing their selection, their potential and applicability. The paper discusses some related key challenges and constraints and also focuses on the needs and future research prospects in this field.

The shift in consumers’ and industries’ perceptions directed the further approach to achieve portable, user and environmental friendly biosensing techniques. Despite of these developments, it was still observed that the comparison among the different biosensors and their categories proved tedious on a single platform; since the food matrices tested, pathogen detected or diagnosed, time of detection, etc., varied greatly and very few products have been commercially launched. Conclusively, a challenge lies in front of food scientists and researchers to maintain pace and develop techniques for efficiently catering to the needs of the food industry.

Biosensors deduction limit varied with the food matrix, type of organism, material of biosensors’ surface, etc. The food matrix itself consists of complex substances, and various types of food are available in nature. Considering the diversity of food there is a need to develop a universal biosensor that can be used for all the food matrices for a pathogen. Further research is needed to develop a pathogen-specific biosensor that can be used for all the food products that may have accuracy to eliminate the traditional method of deduction.

The present paper summarized and categorized the different types of biosensors developed for food-borne pathogens.
