Determination of the magnetocaloric effect associated with martensitic transition in Ni46CunMn38Sn12 and Ni50CoMn34In15 Heusler alloys

This paper presents a study of the inverse magnetocaloric effect （MCE） corresponding to martensitic transition using various experimental approaches for Ni46Cu4Mn38Sn12 and NisoCoMn34In]5 Heusler alloy. Through heat capacity measurements, it is found that the ＂giant inverse MCE＂ upon martensitic transition evaluated by the Maxwell relation in these alloys are unphysical results. This is due to the coexistence of both martensitic and austenitic phases, as well as thermal hysteresis during martensitic transition. However, careful study indicates that the spurious results during martensitic transition can be removed using a Clausius Clapeyron equation based on magnetization measurements.     

度假旅游情境中地方依恋对游客公民行为的影响——基于心理所有权视角

游客公民行为是促进旅游地保持竞争力、实现持续发展的重要推手,现有研究主要参照顾客公民行为的逻辑框架,未能突出旅游情境和游客群体的独特性。以浙江省3个国家级旅游度假区游客为研究对象,基于社会交换理论和心理所有权理论,构建了一个可调节的中介模型,探究地方依恋、地方心理所有权、自我提升动机与游客公民行为的关系。用SPSS 22.0和AMOSS 23.0软件分析收集到的419份样本数据,结果表明：地方依恋正向影响地方心理所有权和游客公民行为;地方心理所有权正向影响游客公民行为;地方心理所有权对地方依恋与游客公民行为之间的关系起部分中介作用;自我提升动机正向调节地方心理所有权与游客公民行为的关系,同时正向调节地方心理所有权的中介作用。
