试谈素质教育中实践能力的培养

素质教育的目的是全面贯彻党的教育方针,提高国民素质,培养学生的创造精神和实践能力。而实践能力是人的能力的重要成分,是学会做事的具体体现,是学生生存发展的需要。教育要注重知行统一,坚持教育教学与生产劳动、社会实践相结合,增强学生解决实际问题的本领和自主探究学习的能力。     

可行能力视角下农户参与农地整理规划的意愿与影响检验——基于安徽寿县4个典型镇的实证分析

[目的]提升农户参与的意愿与探寻有效参与机制。[方法]文章以安徽省寿县4个典型镇的147户农户与4个项目为调查对象,从农户的可行能力视角出发,运用Logistic模型研究农户参与农地整理规划意愿的驱动因素,运用ArcGIS10.0的空间分析功能检验农户参与对规划的影响。[结果]非农业收入比例、农地整理政策了解度、排灌沟渠布局、田间道路密度及公众参与机制等5类因素有显著推动作用;对规划的影响表现在较大程度优化了规划方案,提高了农地生产率等,但耕作田块扩大效应不显著、排灌沟渠存在空间集聚现象、偏好生产路建设及轻视田间林网工程建设等弊端制约了农业规模化经营、忽视规划全局性与环境效应等。[结论]可通过强化农地整理政策宣传力度、完善引导农户式的公众参与机制及基于农户可行能力视角构建农地整理规划效果的衡量尺度以提升农户参与的意愿与探寻有效参与机制。

Global value chains,large-scale farming,and poverty: Long-term effects in Senegal

This paper presents panel data evidence on the impact of expansion of global value chains and large-scale export-oriented farms in developing countries over almost a decade. We estimate the income effects of wage employment on large-scale farms in the horticultural export sector in Senegal, using data from two survey rounds covering a seven-years period of rapid expansion of the sector. We estimate average income effects as well as heterogeneous income effects, using fixed effects and quantile fixed effects regressions. We find that poverty and inequality reduced much faster in the research area than elsewhere in Senegal. Employment in the horticultural export sector is associated with higher household income and the income effect is strongest for the poorest households. Expansion of the horticultural export sector in Senegal has been particularly pro-poor through creating employment that is accessible and creates substantial income gains for the poorest half of the rural population. These pro-poor employment effects contrast with insights in the literature on increased inequality from rural wage employment.     

IMMIGRANT RELATIVE WAGES AT THE GREAT RECESSION: EVIDENCE WITH MATCHED EMPLOYER‐EMPLOYEE DATA FOR SPAIN

The article examines relative wages of immigrants in Spain, with a particular focus on the impact of the Great Recession. The empirical analysis is restricted to men and is based on matched employer‐employee microdata and the decomposition techniques of Juhn et al. (1991, 1993) and Fortin et al. (2011). Our results show that the significant native‐immigrant wage gap that exists both in terms of average wages and of differentials along the wage distribution is essentially explained by differences in the endowments of observed characteristics so that, in general, immigrants tend to receive a similar wage treatment than Spaniards with analogous observed attributes. On the other hand, the Great Recession has had a noticeable impact on the relative wages of immigrants, given that the significant increase of the native‐immigrant wage gap observed during the previous expansionary period was mitigated during the economic downturn due to composition effects arising from the severe employment destruction pattern.     

German stagnation versus Swedish progression: gender wage gaps in comparison, 1960–2006

This article provides a comparative analysis of the development of the gender wage gap in West Germany and Sweden during the period 1960–2006. Despite the economic similarities including broad social safety nets, the gap has developed differently since 1960. This analysis accounts for micro- and macroeconomic factors and politics and concludes that norms and traditions penetrate institutional settings and ensnare Germany in a cultural trap with regard to gender equality. While Sweden has moved to a two-earner model, German society expects mothers to stay at home. The micro analysis shows that family concerns (e.g. marriage and motherhood) decrease female income in Germany to a far greater extent than do such factors in Sweden, which can be explained in part by deeply held social attitudes.     

‘HAVE YOU FELT ANGRY LATELY?’: A NOTE ON UNFAIR WAGE PERCEPTIONS AND THE NEGATIVE EMOTION OF ANGER

The author analyses the nexus between unfair wage perceptions of workers and the frequency of the negative emotion of anger. For this purpose, German household panel data for the years 2007, 2009, 2011 and 2013 are used. Angry feelings in the last four weeks have occurred significantly more frequently for workers who perceive their wage as unfair, whereas the own absolute hourly wage is not significantly correlated with the frequency of having felt angry. The results further indicate that workers have felt more often angry if working hours are larger; but the economic significance seems rather small compared to unfair wage perceptions.     

Does raising indigent defender pay rates improve defendant outcomes? Evidence from New York

Beginning 1 January 2004, the rates paid to assigned counsel – private attorneys who defend the indigent in criminal cases when a public defender does not – were raised from a maximum of $40 per hour to $75 per hour in the state of New York. This article examines the extent to which this relatively large pay increase affects case outcomes. Efficiency wage theory would suggest paying workers higher rates can improve their productivity, and the results of this analysis are consistent with this. Using a difference-in-difference approach, I find that after the assigned counsel rate increase, case outcomes significantly improved in counties with higher poverty rates relative to those with lower poverty rates. The likelihood of conviction and the likelihood of pleading guilty both fell by more than two percentage points in high-poverty counties compared to low-poverty counties after the rate increase, and the differences in the likelihood of being convicted are especially pronounced for cases involving violent felonies. The results suggest raising assigned counsel rates can be an effective policy tool to improve indigent defence systems that are in need of reform.     

Land prices and unemployment

We integrate the housing market and the labor market in a dynamic general equilibrium model with credit and search frictions. We argue that the labor channel, combined with the standard credit channel, provides a strong transmission mechanism that can deliver a potential solution to the Shimer (2005) puzzle. The model is confronted with U.S. macroeconomic time series. The estimation results account for two prominent facts observed in the data. First, land prices and unemployment move in opposite directions over the business cycle. Second, a shock that moves land prices also generates the observed large volatility of unemployment.     

Labor Unemployment Concern and Corporate Discretionary Disclosure

We investigate how firms strategically vary their disclosure policies in response to labor unemployment concern. Using changes in state unemployment insurance laws as exogenous variations of labor unemployment concern, we show that firms provide more bad news forecasts when unemployment concern is low. This relation is stronger when firms are financially constrained, when CEOs and CFOs have higher equity incentives, and when workers are likely to be affected more by unemployment. Our findings are not driven by earnings management reversal or underlying performance changes, and are robust to a battery of identification tests. Finally, we find a similar effect of unemployment concern on disclosure using the tone of 10‐K and 10‐Q filings as an alternative proxy for corporate disclosure. Overall, our findings suggest that labor unemployment concern is an important consideration for corporate discretionary disclosure.
