Letter written by Union soldier W. W. Hawkins to his father. The letter is dated November 20, 1862 from "Camp at Fairmount, Near Fredericksburg, VA." The letter contains comments about military life (marching, lack of rations, talking with Confederate soldiers encamped across the river, cavalry foraging for food).

The year 1999 marked the beginning of reforms in social insurance in Poland. Changes which were implemented then regarded mainly retirement insurance. Until the reform was introduced, the retirement insurance had operated under a pay-as-you-go system. However, political changes in Poland, as well as adverse demographic trends, led to ineffective functioning of the existing system of financing liabilities arising from retirement insurance. It was necessary to introduce changes that, above all, would allow for maintaining an appropriate level of retirement pension. The following article concentrates on one selected aspect of this insurance - Open Pension Funds (in Polish: Otwarte Fundusze Emerytalne; OFEs) and presents major changes occurring in 2002-2018, their reasons and effects. The analysis is mainly based on data from the Financial Supervision Authority and the Social Insurance Institution.

In spatial econometrics,Wrefers to the matrix that weights the value of the spatially lagged variable of other units. As unimportant as it may appear,Wspecifies, or at least ought to specify, why and how other units of analysis affect the unit under observation. This article shows that theory must inform five crucial specification choices taken by researchers. Specifically, the connectivity variable employed inWmust capture the causal mechanism of spatial dependence. The specification ofWfurther determines the relative relevance of source units from which spatial dependence emanates, and whether receiving units are assumed to be identically or differentially exposed to spatial stimulus. Multiple dimensions of spatial dependence can be modeled as independent, substitutive or conditional links. Finally, spatial effects need not go exclusively in one direction, but can be bi-directional; recipients can simultaneously experience positive spatial dependence from some sources and negative dependence from others. The importance ofWstands in stark contrast to applied researchers' typical use of crude proxy variables (such as geographical proximity) to measure true connectivity, and the practice of adopting standard modeling conventions rather than substantive theory to specifyW. This study demonstrates which assumptions these conventions impose on specification choices, and argues that theories of spatial dependence will often conflict with them.
