Compensating restrictive fisheries management measures: distribution of improved cocks to Kainji Lake communities 1997-2001

The Nigeria-German Kainji Lake Fisheries Promotion Project (KLFPP) promoted the distribution of genetically improved cocks to the Kainji Lake (Nigeria) fishing communities aiming to compensate for possible short-term income losses due to the implementation of fisheries management measures restricting the use of the Lake's resources and to provide alternative sources for income generation, especially for the women. Out of 5,075 cocks produced, 4,171 cocks were distributed at subsidized prices mainly to women in 116 fishing villages of Kainji Lake. During an impact survey carried out in 12 villages, 6-24 months after distribution, only 25% of the cocks distributed were seen. However, potential income for each beneficiary from the hybrid offspring was estimated at minimum 1,000 Naira per year

Factors behind the wage in the Basque Country

[EN]This project aims to determine the factors which influence workers’ wages in the Basque Country, taking data from the INE (Spanish Statistical Office). In first place, I will decide which variables to choose and describe them. Then they will be used to build a wage model. At this point I will observe their behaviour according to their values and the possible differences between them. Once these variables are described, they will be used to develop an econometric model that will allow to see the different effects of the variables on the endogenous variable, in this case the gross annual wage. Finally, all the analysed data will be taken and examined to draw the final conclusions and see how workers’ age, training or gender affect their salary. [EN]

Dispersion-compensating photonic crystal fibers with special characteristics

Based on the modified dual core structure, three kinds of special photonic crystal fibers are presented, which are extremely large negative dispersion, super-broad bond, and large area made field dispersion-compensating photonic crystal fibers (DCPCF). For extremely large negative dispersion DCPCF, the peak of negative dispersion reaches -5.9 x 10(4) ps/(mn km). Super-broad bond DCPCF has broadband large negative dispersion and the dispersion value varies linearly from -380 ps/(nm km) to -420 ps/(nm km) in the C band. The designed large area made field DCPCF has a peak dispersion of -1203 ps/(nm km) with the inner core mode area of 47 mu m(2) and outer core mode area of 835 mu m(2). Furthermore, for the large area mode field DCPCF, the experimental result is also obtained. (C) 2008 Wiley Periodicals, Inc.

Realization of highly uniform self-assembled InAs quantum wires by the strain compensating technique

Self-assembled InAs quantum wires (QWRs) on InP(001) substrate have been grown by molecular-beam epitaxy, using a strain compensating technique. Atom force microscope, Transmission electron microscopy, and high-resolution x-ray diffraction are used to characterize their structural properties. We proposed that, by carefully adjusting composition of InAlGaAs buffer layer and strain compensating spacer layers, stacked QWRs with high uniformity could be achieved. In addition, the formation mechanism and vertical anti-correlation of QWRs are also discussed. (c) 2005 American Institute of Physics.

Performance assessment in serious games: Compensating for the effects of randomness

This paper is about performance assessment in serious games. We conceive serious gaming as a process of player-lead decision taking. Starting from combinatorics and item-response theory we provide an analytical model that makes explicit to what extent observed player performances (decisions) are blurred by chance processes (guessing behaviors). We found large effects both theoretically and practically. In two existing serious games random guess scores were found to explain up to 41% of total scores. Monte Carlo simulation of random game play confirmed the substantial impact of randomness on performance. For valid performance assessments, be it in-game or post-game, the effects of randomness should be included to produce re-calibrated scores that can reasonably be interpreted as the players´ achievements.

Shore height and differentials between macrobenthic assemblages in vegetated and unvegetated areas of an intertidal sandflat

Intertidal macrobenthic faunal assemblages of a dual seagrass/callianassid-structured sandflat system were investigated in subtropical Moreton Bay, Queensland. Consistently across all 20 stations, the gastropod-dominated seagrass supported greater abundance (2.5×) and species richness (2×) than the amphipod-dominated sandflat. There was no evidence of along-shore or up-shore variation in the overall assemblage properties such as total abundance, species richness or diversity within either habitat type, except for variation in sandflat abundance between sites. But seagrass and sandflat assemblages both varied significantly in composition from site to site, and seagrass assemblage composition also varied with shore height. Shore height and site, however, only accounted for ≤41% of total variation. The two faunal assemblages showed a Bray–Curtis dissimilarity of 97.7% and within-habitat similarities of <20%. There was no consistency in distribution of greater diversity, dominance or evenness. No differential between any assemblage features in adjacent sandflat and seagrass samples changed with shore height, supporting hypotheses that such differentials are not maintained by predation. Macrofaunal species richness and diversity were closely coupled within sandflat stations but were uncoupled within seagrass ones, questioning the value of diversity as a comparative measure.

Minimum Wage Regulation under Devolution in Northern Ireland

This paper assesses the development and functioning of regional minimum wage regulation in Northern Ireland in the interwar period under a federal form of devolution. Unlike current devolution arrangements in Scotland and Wales, this gave the Stormont Parliament powers over employment and minimum wage regulation. Northern Ireland Trade Boards were set up by the Ulster Unionist Government under the Trade Boards (Northern Ireland) Act 1923 and functioned along the same lines as those in Great Britain. Uniquely in the UK in this period, employer opposition resulted in the main Trade Board in the Irish Linen Industry being replaced by voluntary collective bargaining machinery. About one-quarter of employees were covered by minimum wage regulation, including two-thirds of females in Belfast, keeping a protective floor under low pay.

The demand for labor: An analysis using matched employer-employee data from the German LIAB. Will the high unskilled worker own-wage elasticity please stand up?

This paper uses matched employee-employer LIAB data to provide panel estimates of the structure of labor demand in western Germany, 1993-2002, distinguishing between highly skilled, skilled, and unskilled labor and between the manufacturing and service sectors. Reflecting current preoccupations, our demand analysis seeks also to accommodate the impact of technology and trade in addition to wages. The bottom-line interests are to provide elasticities of the demand for unskilled (and other) labor that should assist in short-run policy design and to identify the extent of skill biases or otherwise in trade and technology.
