With the fantastic features of smartphones, smartphone addiction is a prevalent phenomenon. However, there is a lack of theory-based understanding of how smartphone addiction affects employees’ personal and work lives. The purpose of this study is to investigate the role of smartphone addiction in reinforcing techno exhaustion and life invasion and the final effects of these factors on job performance, and this study applied stress–strain-outcome (SSO) as the foundation of the model. In total, 475 responses were obtained from office and (...) service workers in Iran by a survey. Our findings show that smartphone addiction leads to enhancement in job performance, whereas it significantly strengthens life invasion and techno exhaustion, and thereby life invasion and techno exhaustion dramatically reduce job performance. Our findings indicate the two-sided role of direct and indirect effects of smartphone addiction. Implications for both organizations and employees are discussed. • Stressor-strain-outcome framework is utilized to examine smartphone addiction. • Smartphone addiction leads to enhancement in job performance. • Smartphone addiction significantly strengthens life invasion and techno exhaustion. • Life invasion and techno exhaustion dramatically reduce job performance. • The negative indirect effects of smartphone addiction are more powerful than its positive direct influence.

The present study sets out to investigate the role of ‘culture’ as one of the many important factors that influence the evaluation of politeness in Persian from a Cultural Linguistics perspective. The paper argues that Cultural Linguistics, and in particular the notion of cultural schema, has the potential to offer a robust analytical framework for the exploration of polite use of language. We elaborate on this proposal by presenting examples of data from Persian in which speakers interpret impolite behaviour in (...) light of a number of Persian cultural schemas. The study also offers a novel three-layered approach for the analysis of politeness data that combines metadiscourse analysis with the ethnography of cultural conceptualisations, while highlighting the importance of the notion of ‘heterogeneous distribution’ of cultural conceptualisations, a pivotal theoretical concept in Cultural Linguistics which accounts for the variations in speakers’ evaluation of politeness.

Anxiety is a common unpleasant reaction among patients undergoing surgery. Many non-pharmacological methods such as spiritual strength are effective in preoperative anxiety management. This study aimed to assess the effects of listening to Quran recitation on reducing preoperative anxiety. A systematic review was performed in Medline, EMBASE, Cochrane Library, PsycINFO, Arab World Research Source, and other relevant databases to collect the data. Randomized controlled trials about the effects of listening to Quran recitation on preoperative anxiety reduction in elective surgery were (...) selected without any language and date restriction. Interventions with self-reading/self-recitation were excluded. The Cochran’s Q statistic and the I2 index with 50% threshold were used for calculating the heterogeneity and inconsistency index. Subgroup analysis was conducted based on the surgery type. The funnel plot was used to evaluate the possibility of publication bias. Twelve studies were included in the qualitative synthesis and nine studies in the quantitative synthesis. The meta-analysis showed a significant anxiety reduction with listening to Quran recitation. The heterogeneity between the included studies was statistically significant. The pooled effect size of anxiety was d = −8.893 = −10.763 to −7.022). The subgroup analysis showed that listening to Quran recitation reduces anxiety in major and minor surgeries. There was no publication bias in the studies. The findings indicated that listening to Quran recitation can be considered a non-invasive and peaceful intervention to reduce preoperative anxiety in elective surgery. (shrink)

Chronic back pain (CBP) is a leading cause of disability and results in considerable socio-economic burdens worldwide. Although CBP patients are commonly diagnosed and treated with a focus on the ‘end organ dysfunction’ (i.e., peripheral nerve injuries or diseases), the evaluation of CBP remains flawed and problematic with great challenges. Given that the peripheral nerve injuries or diseases are insufficient to define the etiology of CBP in some cases, the evaluation of alterations in the central nervous system becomes particularly necessary (...) and important. With the development of advanced neuroimaging techniques, extensive studies have been carried out to identify the cortical abnormalities in CBP patients. Here, we provide a comprehensive overview on a series of novel findings from these neuroimaging studies to improve our understanding of the cortical abnormalities originated in the disease. First, CBP patients normally exhibit central sensitization to external painful stimuli, which is indexed by increased pain sensitivity and brain activations in pain-related brain regions. Second, long-term suffering from chronic pain leads to emotional disorders, cognitive impairments, and the abnormalities of the relevant brain networks among CBP patients. Third, CBP is associated with massive cortical reorganization, including structural, functional, and metabolic brain changes. Overall, a deep insight into the neural mechanisms underlying the development and outcome of CBP through more sophisticated neuroimaging investigations could not only improve our current understanding of the etiology of CBP but also facilitate the diagnosis and treatment of CBP based on precision medicine.
