溯古述今志苑精品--读《洪泽湖志》

我读到《洪泽湖志》,喜不自禁,这是我早就期盼能够读到的志书! 我对名山大川志有一种偏爱,想读的自然首先是家乡的山水志.离我家最近的名山是云台山,最近的名水是洪泽湖.但在旧志书中,只有《云台山志》《云台新志》,洪泽湖没有志,这使我感到十分遗憾.在再度兴起的新中国首轮修志接近尾声、第二轮修志工作陆续展开之际,淮安市地方志办公室终于填补了志林中这一空白,推出了第一部《洪泽湖志》.拜读了荀德麟主编的洋洋137万多字的《洪泽湖志》之后,我为志苑中又增添一部精品力作兴奋不已,对《洪泽湖志》取得的成功表示由衷的祝贺! 下面我谈点读后感想.     

A Flexible Mathematical Programming Model to Estimate Interregional Input–Output Accounts*

Abstract. This study implements and tests a mathematical programming model to estimate interregional, interindustry transaction flows in a national system of economic regions based on an interregional accounting framework and initial information of interregional shipments. A national input–output (IO) table, regional data on gross output, value‐added, exports, imports, and final demand at sector level are used as inputs to generate an interregional IO account that reconciles regional economic statistics and interregional transaction data. The model is tested using data from a multiregional global IO database and shows remarkable capacity to discover true interregional trade patterns from highly distorted initial estimates.     

Force Reduction, Base Closure, and the Indirect Effects of Military Installations on Local Employment Growth

Abstract This study examines the indirect effects of military installations on county–level private employment, and specifically the special cases of base closure under the Base Realignment and Closure (BRAC) proceedings of 1988, 1991, 1993, and 1995. Local employment impacts are considered within a partial adjustment construct of the changes model, a specification that facilitates the decomposition of defense personnel changes into their positive, negative, and BRAC–related components. The latter two components are subsequently examined for asymmetric effects attributable to ordinary force drawdown on the one hand, and base closure on the other. Also considered are the specific effects of direct federal assistance as well as facilities conversion and reutilization within BRAC communities.

岩画病害的红外热成像检测技术初探

为探索红外热成像检测技术在岩画病害检测中的可行性,利用红外热像仪对广西花山岩画的病害进行了检测。检测结果表明,利用红外热成像技术可以有效检测岩画中的钟乳石覆盖、片状剥离及渗水病;不同病害其检测的最佳时段不同,钟乳石在夜间或早晨进行检测效果好,而片状剥离岩石使用午后的热像检测效果好;与可见光检测相比,红外热成像检测具有独特优势。     

替代抑或补充:网上购物与传统购物出行的关系研究

有关网上购物与传统购物的关系问题是当前电子商务领域的研究热点之一,但研究结论还不尽一致。许多人认为网上购物将替代传统购物方式,但是也有其他的观点表明应是一种促进或者补充的关系,甚至有人觉得这种影响是很小的。本文通过对大学生购书行为的调查,采用统计方法分析了网上购物对传统购物出行的影响作用。结果表明:总体上,网上购物对消费者传统购物出行的影响并不显著,网上购物还只是作为消费者原有购物出行的一种补充方式,并不会对大多数消费者的传统出行频率和出行距离造成明显的影响。一方面,网上信息浏览和网上购物对传统日常购物出行的影响主要表现为消费者日常出行频率和距离的缩减以及多目的出行频率的上升。另一方面,网上行为可能使消费者非日常出行频率增加,单次出行距离增长。总之,网上购物与传统购物出行的关系并不是简单的替代或者补充,而是要复杂地多。     

Wine and olive oil permeation in pitched and non-pitched ceramics: relation with results from archaeological amphorae from Sagalassos,Turkey

Pitch compounds are frequently identified inside archaeological ceramic vessels. As their presence might affect the permeation of oil or wine into the ceramic fabric, experiments were conducted in which the diffusion of lipids or polyphenols into pitched and non-pitched modern vessels was followed by chemical analysis. Results show that the polyphenols of wine can intrude into the ceramics even through a pitch layer. Consequently, the absence of polyphenols in archaeological sherds is not due to their inability to reach the ceramic matrix under the pitch layer. By contrast, a pitch layer is quite effective to avoid oil intrusion into the ceramic matrix. Thus, it seems logical that oil amphorae would have been coated with pitch at the inside prior to use. Experiments in which the pitched ceramic was simultaneously exposed to oil and wine, show that the wine makes the pitch more permeable for the lipid compounds. These experimental data are confronted with residue analysis results obtained on amphorae fragments excavated in Sagalassos, Turkey. Pitch and oil were frequently found together. Based on a polyphenol test, indications for wine storage could only be obtained for two vessels. Against this background, the possible uses of the Sagalassos amphorae are discussed, and the traditional association of pine pitch with wine storage in archaeological amphorae is critically assessed.     

Opportunities and constraints for intensive agriculture in the Hawaiian archipelago prior to European contact

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km² of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km², all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial.
