How did Brexit impact EU trade? Evidence from real data
(John Wiley and Sons Inc, 2023) Buigut, Steven; Kapar, Burcu
At the time it voted to exit in 2016, the UK was a leading economy within the EU. It contributed about 16 percent of the EU GDP, while the other EU countries accounted for almost half of UK's total trade. This study attempts to answer two research questions: First, how Brexit affected the EU–UK trade and second, how it affected the trade between remaining 27 EU members. To answer these questions, quarterly data are exploited for the period from 2005Q1 to 2022Q3 covering a total of 53 trading partners including the EU members. A gravity model that controls for unobserved bilateral heterogeneity and multilateral resistance is estimated by PPML. Three phases of Brexit (the referendum, transition, and post transition [under the TCA]) are analysed. The results indicate that the Brexit referendum phase depressed UK–EU trade by around 10.5%, and transition phase by around 15%. In both cases, particularly for the transition phase, the effect is greater on the UK imports from EU than the UK exports to EU. We do not find a significant effect due to the post transition (TCA) phase. Estimates show some mild but positive effect on intra-EU trade of about 1.5% and 4.6% due to Brexit referendum and post Brexit respectively, but no significant effect from the transition phase. This suggests that some EU trade with the UK was redirected to other EU members. Hence UK should aggressively seek out new trade agreements with other countries and trade blocs as well as refine the workings of the trade and cooperation agreement signed with the EU to minimise the loss. © 2023 The Authors.

Development and Validation of the Soft Skills Questionnaire for Nurses
(SAGE Publications Inc., 2023) Aridi, Mona; Ahmad, Manal; Ghach, Wissam; Charifeh, Samiha; Alwan, Nisreen
Introduction: Skills challenge has been given great attention for its impact on employees’ performance. Various approaches have been put forward to design professional development programs that help in preparing nurses to work in the field and ongoing training programs to keep them up to each new method and technique at the interpersonal improvement level. Objective: To develop and validate a questionnaire that tests the communication and management skills, emotional intelligence, and confidentiality of nurses in Lebanon. Methods: The questionnaire, consisting of 25 statements, was generated and developed by experts in the field of nursing, soft skills, and questionnaire development. The items of the questionnaire were assessed using face, content, and construct validity and data validation was examined through psychometric properties at the final stage of the validation. Internal consistency and reliability were assessed through Cronbach alpha ((Formula presented.)). Further analyses were carried out to decide on the number of factors to be extracted using Oblimin Rotation method. All statistical tests were performed using Statistical Package for the Social Sciences (SPSS 20.0). Results: Nineteen items of the 25-item scale had an I-CVI of 1.00 and the remaining six items had an I-CVI of 0.87. The S-CVI/UA was 0.76 and the S-CVI/Ave was 0.97, which meant that the items were good for the underlying construct. For the psychometric measures, the results were quite accepted and satisfactory. The Kaiser–Meyer–Oklin measure of sampling adequacy and the significance for the Bartlett's test for the whole questionnaire were quite acceptable with 0.680 and 0.000, respectively. Furthermore, the Cronbach alpha (α) value was 0.824 indicating a high internal consistency between the items of the questionnaire. While obtaining exploratory factor analysis for each section, results showed that Oblimin Rotation method should be applied to the last section in which three items were eliminated to maintain a simple factor structure. Conclusion: This study shows that the 25-item Soft Skills Questionnaire is a valid and reliable tool for evaluating the level of communication of nurses, their emotional intelligence, confidentiality, and management. © The Author(s) 2023.
