The role of satisfaction in labor diaspora dynamics: An analysis of BREXIT effects

In diaspora research, people's international mobility is often understood as a response to pull-push forces on an economic macro-level or as part of diasporic waves. However, labor diaspora formations are also influenced by micro-level (i.e., individual perceptions) drivers related to work per se, such as satisfaction. This explorative qualitative study takes a novel angle and focuses on the role of Portuguese nurses’ satisfaction with the evaluation of the Brexit scenario and its effects on this labor diaspora's mobility and stability. The findings illustrate that satisfaction, although affected by uncertainty, mainly relates to perceived working conditions and legislation and the possibilities to communicate with locals and other diasporans. This paper provides suggestions for future research and contributes to the development of theory on staying and human stickiness, explaining the dynamics of exit and entry in (re-)migration decision making.     

Stuck at the bottom: Role of tacit and explicit knowledge on innovation of developing-country suppliers in global value chains

We take a social exchange theoretical perspective of innovation to develop and test a model of the intervening role of tacit and explicit knowledge exchange in explaining innovation of developing-country suppliers in non-equity-based global value chains (NEGVCs). Results of structural equation modelling for a sample of Bangladeshi suppliers embedded in apparel NEGVCs show that tacit and explicit knowledge fully mediate the associations between network competence and both low value-added and high value-added innovation contingent on the quality of network relationships. We also found that both tacit and explicit knowledge contribute more to low value-added innovation than to high value-added innovation. The managerial and policy implications of our findings as to why developing-country suppliers in NEGVCs are stuck in low value-added activities are fully discussed.     

Health shocks and mortgage debt payoff among American homeowners over age 50: A survival analysis

Mortgage debt is financially burdensome for many older homeowners in the United States. As people age, declining health can bring about increased healthcare costs. Focusing on homeowners aged 50 and older in the U.S., we investigate two research questions: (1) To what extent does a heath shock affect the likelihood of paying off a mortgage voluntarily or involuntarily? and (2) how long does a health shock delay the time it takes to pay off a mortgage? We used eight biannual waves (2004–2018) of the Health and Retirement Study containing 11,772 borrowers to build survival regression models. Results showed that a health shock reduced the likelihood of voluntary payoff by 12%, while it increased the probability of involuntary payoff by 18%. A health shock delayed voluntary and involuntary payoffs for 30 and 21 months, respectively. We discuss tax deduction and HELOCs as strategies to reduce older homeowners' mortgage strain.     

The medical expense deduction and income levels: Progressive or regressive?

The medical expense deduction (MED) allows taxpayers to deduct from taxable income a proportion of their out-of-pocket medical insurance and health care expenses. Because the rate of subsidy is equal to the marginal tax rate previous studies have found MED to be a regressive tax mechanism biased toward benefiting higher-income taxpayers. The authors demonstrate, using GINI coefficients, that MED makes the tax structure more progressive than it would otherwise be and increases equality of after-tax incomes.

不同生计模式下六盘山区易地扶贫搬迁移民生计资本耦合协调研究——以甘肃省古浪县为例

[目的]探究易地扶贫搬迁移民的生计耦合协调有助于全面了解移民的生计问题,对提高移民可持续生计能力及后续发展提供参考。[方法]文章以甘肃省古浪县易地扶贫搬迁家庭为研究对象,通过2019—2021年实地访谈和问卷调查等方法对移民家庭的生计状况进行调查,选取测度指标并计算各类移民的生计资本值,根据移民收入来源对生计模式进行分类,运用耦合协调度模型分析各生计模式下移民5项生计资本间的关系。[结果]（1）生计资本内部耦合水平总体较低,处于低度耦合和失调衰退等级;（2）非农型的生计资本耦合度和协调度最高,分别为0.299和0.230,是最为接近中度耦合和过渡协调阶段的生计模式;（3）两类兼业户的次之,处在（0.15,0.3）的区间内,属于低度耦合和衰退协调的中高级阶段;（4）纯农户的较低,为0.172和0.223,处于低度耦合和协调衰退的中阶段;（5）补贴户的最低,耦合度、协调度均在（0,1）的区间,处在低度弱耦合和恶性失调等级。[结论]古浪县不同生计模式下易地扶贫搬迁移民的生计资本存量和差距,导致其耦合协调性较差、差异较大。     

The out-of-sample forecasting performance of nonlinear models of regional housing prices in the US

This article provides out-of-sample forecasts of linear and nonlinear models of US and four Census subregions’ housing prices. The forecasts include the traditional point forecasts, but also include interval and density forecasts, of the housing price distributions. The nonlinear smooth-transition autoregressive model outperforms the linear autoregressive model in point forecasts at longer horizons, but the linear autoregressive and nonlinear smooth-transition autoregressive models perform equally at short horizons. In addition, we generally do not find major differences in performance for the interval and density forecasts between the linear and nonlinear models. Finally, in a dynamic 25-step ex-ante and interval forecasting design, we, once again, do not find major differences between the linear and nonlinear models. In sum, we conclude that when forecasting regional housing prices in the United States, generally the additional costs associated with nonlinear forecasts outweigh the benefits for forecasts only a few months into the future.     

中水源热泵地板供暖运行策略分析

为研究中水源热泵地板供暖系统的节能策略,以石家庄市某实际运行小区的中水源热泵地板辐射供暖系统为对象,引入室外综合温度的概念,综合考虑室外气温、太阳辐射热与风速等环境因子的影响,推导得出了地板辐射供暖系统质调节情况下,保证热用户舒适度的二次网供、回水温度调节公式。经实际运行测试,由该调节公式计算得出的二次网供、回水温度作为地板辐射供暖系统分时段质调节的依据,可以在满足热用户舒适度要求的情况下,取得良好的节能效果。中水源热泵系统与地板辐射供暖系统的结合及推广为城市集中供热提供了新思路。     

Life after school: How science and technology teachers construe capability

Science and technology teachers create microcosms of the world beyond school as responses to perceived student needs. The focus of these microcosms for both science and technology classrooms was less of a concern for work preparation than for the development of social and intellectual habits. All of the teachers have strong views of the virtues of civil daily life and what it might take for their students to live the good life. The practical capability the teachers want their students to have transcends the instrumental to become moral.     

西部大开发中的金融市场建设

西部金融市场应该是开放型、复合型的金融市场。开拓完善西部金融市场宜树立大金融概念,从财政、金融、证券、保险、基金等方面着手。面对国际、国内市场化的社会经济环境,构建西部金融市场应主要依靠市场机制的力量,同时,也需要政府部门强有力的扶持。在西部大开发初期,政府的宏观调控和政府扶持尤其重要,本文就此提出了六点金融政策创新建议。
