    Opis:
    Bonylip barb is an Indonesian endemic fish that has not been widely used. One potential application is the addition of bonylip barb fish meat to cream soup products. Cream soup is a thick soup that has a cloudy color due to the addition of milk and holds the prominent aroma and taste of milk. This study aims to determine the amount of bonylip barb fish meat that can be added in to produce the most preferred cream soup. Research on bonylip barb fish cream soup creation was carried out at the Fisheries Technology Laboratory of the Faculty of Fisheries and Marine Sciences, Padjadjaran University. The study was conducted in May-June 2019. The method used was experimental with 4 treatments of bonylip barb fish addition, namely 0%, 10%, 20%, and 30% of dry weight. Organoleptic tests were carried out by 20 semi-trained panellists. The variables observed were organoleptic color, aroma, taste and texture. The results showed that 30% addition of bonylip barb fish produced the most preferred cream soup product. This had a color hedonic mean value of 6.7; aroma 6.5; taste 7.3; and texture 6.8.

    Opis:
    There are reasons researchers may be interested in accounting for spatial heterogeneity of preferences, including avoiding model misspecification and the resulting bias, and deriving spatial maps of willingness-to-pay (WTP), which are relevant for policy-making and environmental management. We employ a Monte Carlo simulation of three econometric approaches to account for spatial preference heterogeneity in discrete choice models. The first is based on the analysis of individual-specific estimates of the mixed logit model. The second extends this model to explicitly account for spatial autocorrelation of random parameters, instead of simply conditioning individual-specific estimates on population-level distributions and individuals’ choices. The third is the geographically weighted multinomial logit model, which incorporates spatial dimensions using geographical weights to estimate location-specific choice models. We analyze the performance of these methods in recovering population-, region- and individual-level preference parameter estimates and implied WTP in the case of spatial preference heterogeneity. We find that, although ignoring spatial preference heterogeneity did not significantly bias population-level results of the simple mixed logit model, neither individual-specific estimates nor the geographically weighted multinomial logit model was able to reliably recover the true region- and individual-specific parameters. We show that the spatial mixed logit proposed in this study is promising and outline possibilities for future development.

    Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS)
    Opis:
    Celem pracy jest rozpoznanie poziomu rozwoju społeczno-gospodarczego powiatów ziemskich województwa wielkopolskiego. Do jego określenia wykorzystano cechę syntetyczną, która jest funkcją cech prostych – wyznaczników cząstkowych poziomu rozwoju społeczno-gospodarczego. W procedurze tworzenia cechy syntetycznej zastosowano do mierzenia odległości od wzorca i antywzorca rozwoju uogólnioną miarę odległości GDM (Walesiak 1993, 2011), a do agregacji cech metodę TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) (Hwang, Yoon 1981, Wysocki 2010). Miara Walesiaka (Walesiak 1993) pozwala na obliczanie odległości pomiędzy cechami opisywanymi na różnych typach skal tj. porządkowych, przedziałowych i ilorazowych. Natomiast metoda TOPSIS jest metodą wzorcową służącą do agregacji cech. Zaproponowane podejście pozwoliło dokonać oceny poziomu rozwoju społeczno-gospodarczego powiatów opisywanych przez cechy proste, zarówno metryczne, jak i porządkowe. W procesie oceny poziomu społeczno-gospodarczego powiatów województwa wielkopolskiego wykorzystano dane statystyczne z ankiety przeprowadzonej w starostwach powiatowych w województwie wielkopolskim nt. Stanu i możliwości rozwojowych powiatów województwa wielkopolskiego (2000) oraz Banku Danych Lokalnych Głównego Urzędu Statystycznego za rok 2010.
    The paper aims to evaluate the level of socioeconomic development of powiats (i.e. second level administrative units) in Wielkopolska province. With this purpose in mind a synthetic feature was utilized that aggregates simple features: partial indicators of socioeconomic development. The procedure of designing this feature used the generalized distance measure GDM to compute the distance from the ideal and anti-ideal points (Walesiak 1993, 2011), and TOPSIS method to aggregate the features (Hwang, Yoon 1981, Wysocki 2010). The measure of Walesiak (1993) facilitates calculating distances between features described on different scale types: ordinal, interval, or ratio, while TOPSIS is the standard method for aggregation of features. Proposed approach allows evaluating the level of socioeconomic development of powiats when expressed through simple features, both metric and ordinal. The evaluation process made use of the data gathered from the survey conducted in the powiat offices of the Wielkopolska province: “The present state and development potential of the powiats of Wielkopolska” (2000) and from the Local Data Bank of the Central Statistical Office report of 2010.
