AbstractThe effects of reinforcement debonding and work hardening on ductile reinforcement toughening of γ-TiAl have been examined. Debonding has been varied by either the development of a brittle reaction product layer or by depositing a thin oxide coating between the reinforcement and matrix. The role of work hardening has been explored by comparing Nb reinforcements that exhibits high work hardening with solution hardened Ti-Nb alloy that exhibits negligible work hardening. It is demonstrated that a high work of rupture is encouraged by extensive debonding when the reinforcement exhibits high work hardening. Conversely, debonding is not beneficial when the reinforcement exhibits low work hardening.

According to the literature, employees who have vigor, dedication and absorp in their work are considered to have a high work engagement and are able to increase productivity. This research was conducted to see the role of transformational leadership and gender to work engagement. Participants are 208 IT sales that sell IT products. The instrument test uses item analysis test, and regression analysis uses multiple regression. The results show that only transformational leadership has a significant relationship with work engagement, that means the higher the role of transformational leaders, the higher level of work engagement is held. While the gender variable does not have a significant relationship with work engagement. Based on the results obtained, the role of transformational leadership is needed by IT sales as a factor that can increase work engagement. Menurut literatur, karyawan yang menampilkan semangat, dedikasi dan tenggelam dalam pekerjaan mereka dianggap memiliki keterikatan kerja yang tinggi serta mampu meningkatkan produktivitas. Penelitian ini dilakukan untuk melihat peran kepemimpinan transformasional dan jenis terhadap keterikatan kerja. Partisipan berjumlah 208 sales IT yang melakukan penjualan produk IT. Uji instrumen menggunakan uji analisis butir, serta analisis regresi menggunakan regresi berganda. Hasil menunjukkan bahwa hanya kepemimpinan transformasional yang berperan secara signifikan terhadap keterikatan kerja, artinya semakin tinggi peran pemimpin transformasional yang dirasakan maka semakin tinggi pula tingkat keterikatan kerja yang dimiliki. Sedangkan variabel jenis kelamin tidak berperan terhadap keterikatan kerja. Berdasarkan hasil yang diperoleh, peran kepemimpinan transformasional diperlukan oleh sales IT sebagai faktor yang dapat meningkatkan keterikatan kerja.

PurposeThis study introduced a focus on work flexibility-worry and intended to test whether work flexibility-worry would weaken the strengthening power of work flexibility-willingness on the relationship between work flexibility-ability and work–family conflict from the perspective of person–situation interaction.Design/methodology/approachParticipants were 924 employees recruited by the snowballing technique. They completed questionnaires about demographics and work flexibility. Multivariate stepwise regression was used to analyze the collected data.FindingsResults showed that work flexibility-ability can reduce work-to-family conflict. However, this effect is most pronounced only among individuals with a high work flexibility-willingness who simultaneously experience low work flexibility-worry.Practical implicationsFor organizations that want to provide work flexibility benefits to employees, they should not only pay attention to employees' personal preference for work flexibility but also create a climate in which all employees are allowed to use the flexibility supply without criticism from coworkers and without impacting organizational evaluations, which can benefit employees' functioning in both their work and family roles.Originality/valueThis study clarified the joint role of willingness and worry in predicting the extent to which work flexibility-ability reduces work–family conflict, which helps organizations to better understand the conditions under which work flexibility can better reduce work–family conflict.
