AbstractIndividual-level variation is a recurrent issue in variationist sociolinguistics. One current approach recommends addressing this via mixed-effects modeling. This paper shows that a closely related model with fixed effects for individual speakers can be directly estimated using Goldvarb. The consequences of employing different approaches to speaker variation are explored by using different model selection criteria. We conclude by discussing the relation of the statistical model to the assumptions of the research design, pointing out that nonrandom selection of speakers potentially violates the assumptions of models with random effects for speaker, and suggesting that a model with fixed effects for speakers may be a better alternative in these cases.

As the oil offloading operations of floating production storage and offloading (FPSO) units become more routine, the desire grows to increase the availability for offloading and thus decrease production downtime. Experience with these operations is the main tool available to increase the efficiency of this aspect of deepwater production. However, it is clear that a formal optimization approach can help to fine tune design parameters so that not only is availability increased but the significance of each design parameter can be better understood. The key issue is to define the environmental conditions under which the vessels involved in offloading are able to maintain position. By this, we reduce the notion of availability to a set of operating criteria, which can or cannot be met for a particular set of environmental conditions. The actual operating criteria such as relative vessel heading depend on selection of design parameters, such as the direction and magnitude of external force applied by thrusters or tugs. In the earliest offloading operations, engineering judgment was used to determine the feasibility of offloading at a particular time. For example, if wind and current were not expected to exceed a 1year return period, offloading may be considered safe. This approach can be both conservative and unconservative, depending on the nuances of the particular environmental conditions. This study will propose a formal approach to choosing the design parameters that optimize the availability of a FPSO for offloading. A simple analysis model will be employed so that optimization can be performed quickly using a robust second order method. The proposed analysis model will be compared to model test data to demonstrate its agreement with the more complex system.

The portfolio analysis is a method for the strategic selection of energy sources able to drive the sustainable evolution of the renewable energy balance. In this paper the portfolio theory is applied in the Italian electricity market for different renewable energy sources (biomass, hydro, photovoltaic and wind) with the aim to select, by diversification, optimal portfolios that minimize investment risk. This analysis can be useful for energy planners to select future green scenarios based on the increasing use of renewable energy.

Noniterative estimators of the unrestricted factor analysis model have been developed by, among others, Hägglund (1982) and Ihara and Kano (1986) that are consistent and very efficient computationally. Whereas each of these methods has several desirable properties, both require a subjective decision regarding the selection of subsets of variables that are needed to compute estimates of the parameters. An algorithm called PACE, based on an application of the sweep operator, is presented that automatically selects subsets of variables used for the Ihara-Kano estimator. A second algorithm initially presented by Du Toit (1986) is also described that automatically selects reference variables used in Hägglund’s Fabin estimators. A Monte Carlo experiment is reviewed that compares the relative performance of these estimators in addition to several others. Both new methods performed well in this experiment. Their relative merits on other criteria are discussed.

REPRODUCTIVE PERFORMANCE OF BEEF CATTLE IN BINTAUNA DISTRICT OF NORTH BOLAANG MONGONDOW REGENCY. This study was conducted to evaluate the reproduction performance of beef cattle in Bintauna district of North Bolaang Mongondow regency. Reproductive performance was studied to determine the productivity of livestock especially in population increase and availability of meat. This research used samples of farmer as breeder of beef cattle. The selections of village samples were determined purposively by consideration of the villages with the largest population of livestock including the villages of Pimpi, Kopi, and Bintauna. Selection of respondents using random sampling method involved 10 farmers for each selected village, with the total of 30 farmers as respondents. Data of the variables were analyzed using descriptive analysis model. The results showed that the age of puberty animal was 12.03 ± 4.81 months, service per conception was 1.19, conception rate was 73%, pregnancy period was 276 ± 2.53 days, and calving interval was 366 ± 3.21 days. Based on these results, it can be concluded that the reproduction of beef cattle in Bintauna district of North Bolaang Mongondow regency was categorized into good performance. Keyword: Reproduction performance, beef cattle, Bintauna district

This paper discusses how Kompas.com and Republika.co.id framed the coverage of the repatriation of ex-ISIS members to Indonesia. This study was a qualitative study using the approach of Robert N. Entman framing analysis model. The findings revealed that Kompas.com and Republika Online framed the return of the former ex-ISIS fighters to Indonesia differently in terms of the selection of news sources, legal analysis, and approval. Kompas.com tended to choose state officials to be a source to conduct analysis based on state law and reject repatriation of ex-ISIS. Meanwhile, Republika Online tended to select religious leaders to analyse based on Islamic law and allowed them to repatriate to this country. In other words, Kompas.com focused on the principle of humanism, while Republika Online more emphasised on Islam values and nationalism in their news coverage.
