Digital labor, as a new theoretical form of "audience commodity theory" in the digital media era, represents a new form of production and labor. This paper explores the unique features of digital labor in labor form, labor products and labor time, and combining Marx's theory, it further reveals the alienation and exploitation of human social relations, emotional value and social class in the process of digital labor, and finally makes suggestions on the unequal relationship between platform and workers in the process of digital labor.

Boredom is a prevalent emotion in foreign language learning, yet it remains relatively under-researched in the field of applied linguistics. A thorough understanding of the current state of boredom research in foreign language learning can not only enrich the theoretical achievements in the study of emotions in language education but also provide practical insights into effective ways to alleviate students’ feelings of boredom. From the perspective of positive psychology, this paper argues that implementing effective teaching strategies to address students’ boredom in foreign language classrooms is essential. Such strategies can stimulate positive emotions in English learning, ultimately fostering students’ enthusiasm for the subject and enhancing their English performance.

The future of Dutch healthcare is a challenge that focuses on four aims: the ‘Quadruple Aim’. These aims concern: improving the quality and accessibility of care, enhancing patient experience, reducing healthcare costs and increasing the job satisfaction of healthcare professionals. Healthcare professionals play a major role in the realization of the first three aims. The pressure on healthcare and the scarce capacity forces us to treat this human capital with care. Satisfied employees are partly decisive for the success of an organization. At the same time, an organization expects optimal performance from its employees. This requires an active and involved attitude from the HRM department. The individual employee plays an intermediary role between HRM activities and organizational performance. In order to increase knowledge and understanding about this position, attention to the individual in the context of the organization is essential. In this article, the relationship between HRM, performance and well-being of employees and underlying theoretical explanation models are discussed. Recommendations were made on the contribution that HRM can make to the balance between employee and organizational interests.

In the present work, a series of butyl methacrylate/1-hexene copolymers were synthesized, and their efficiency as viscosity index improvers, pour point depressants, and shear stabilizers of lube oil was investigated. The effect of 1-hexene molar ratio, type, and concentration of Lewis acids on the incorporation of 1-hexene into the copolymer backbone was investigated. The successful synthesis of the copolymers was confirmed through FTIR and 1H NMR spectroscopy. Results obtained from quantitative 1H NMR and GPC revealed that an increase in the molar ratio of 1-hexene to butyl methacrylate, along with concentration of Lewis acids led to an increase in 1-hexene incorporation and a reduction in Mn and Ð. Similar trends were observed when the Lewis acid changed from AlCl₃ to organometallic acids. The maximum 1-hexene incorporation (26.4%) was achieved for sample BHY3, with a [1-hexene/BMA] ratio of 4 mol% and a [Yb(OTf)₃/BMA] ratio of 2.5 mol%. Evaluation of the synthesized copolymers as lube oil additives demonstrated that the viscosity index was more significantly influenced by samples with higher molecular weight. Sample BHA13 represents maximum VI of 137. The copolymer containing Yb(OTf)₃ as a catalyst exhibited superior efficiency as a pour point depressant. Furthermore, sample BHY3 showed the lowest shear stability index (6.4).
