According to final results of Census in 2002, total number of declare Gypsies in Serbia (without Kosovo and Metohija) was 108.193, apropos 1.44% in total population of Serbia, conditional third position in rang of ethnic minorities (behind Hungarians and Bosnians). Though, in sense population dynamics of Gypsies, it is needs to know, that official statistic data could give only information about population which "them selves repute Gypsies", declare as Gypsies in that moment, and because of that we are probability to take on scientific observe only number of declare Gypsies. During the period 1948-2002, Gypsies was included on all census statistic classifications of nationalities. But, oscillations in number of Gypsies show population dynamics without any evenly and projected trends of population development. This fact is problem and for official statistic research. Certainly, the main defect at statistic registration of Gypsies is ability to change attitude about nationality declare in censuses.

Qualitative Properties

We study a model of population dynamics describing pregnancy: our model is composed by an equation describing the evolution of the total population, and an equation describing the evolution of pregnant individuals. These equations are of course coupled: one coupling expresses that the total population varies with the number of born people, and another coupling says that the number of fecundated individuals depends on the total population. We study three models of that type: a linear model without diffusion, a nonlinear model without diffusion and a linear model with diffusion. For these three models, we study precisely the qualitative properties and the asymptotic behavior of the solutions.

Diverse Groups

With an increase in the number of diverse groups of individuals (including ethnic minorities) entering organizations, managing diversity in the 21st-century workplace has become imperative. The workplace provides employees with opportunities to work interactively with others in diverse situations and to express their identities, including ethnic identity. Despite Western-based organizations’ adoption of strategies such as affirmative action in an effort to integrate diverse employees into their workplaces, members of ethnic minority groups may still experience great difficulties in obtaining instrumental and social support in these organizations. While some minorities may not outwardly manifest their ethnicity, in the majority of cases, ethnic identity forms a core identity of many individuals and employees do not leave this identity at the doorstep of the organization. In some countries, ethnic minorities have refused to assimilate into the majority workplace culture, and have maintained strong ethnic identities. By outwardly expressing their identities, ethnic minority employees face discrimination, stereotyping and micro-aggressive behaviors within the workplace, and in the majority of cases are relegated to dead-end lower level posts and face barriers to their career advancement. Also, having strong ethnic identities results in a conflict between minorities ethnic identities and the workplace culture. This is especially apparent in terms of religious beliefs and values. Embracing ethnic identity of migrants into organizational cultures is especially challenging for organizations these days, as many immigrants are highly skilled professionals that enter western corporations. They experience discrimination and not receiving support in order to advance their careers.

To study the population dynamics of young-of-the-year spot (Leiostomus xanthurus) I released 6981 marked fish midway up the tidal creek portion of a small (<20 ha) marsh creek–seagrass meadow coenocline. Holding mortality experiments (96 h) indicated that 61.5%, or 4300 individuals, survived the marking process to constitute the population available for recapture. Over a 90-d study period, 212 marked fishes were recaptured. From plots of the ratio of marked to unmarked individuals in subsequent samples, I concluded that the population was resident in the creek for up to 182 d with the average individual present for 91 d. When this population turnover rate was compared to the total population decay rate (marked plus unmarked fish), the exchange between habitats (immigration/emigration) accounted for about 26% of the total decay rate, with the remainder attributed to natural mortality. By correcting the overall disappearance rate for population turnover due to immigration/emigration, and using this adjusted value as a measure of instantaneous mortality (Z), the estimated production in this population was 21.8 kcal (91342 J)∙m−2∙d−1. This figure is over six times greater than previously reported values for this species for all size classes over the entire growing season.

Migration Component

The paper treats the issue of significance of refugee migrations in the last decade of the 20th century, for the changes of total number of inhabitants in the municipalities: Indjija, Ruma, Sremski Karlovci, Stara Pazova and Sid. These municipalities have the highest share of refugees in the total population, according to the 2002 census. The trend of negative natural increase of population in Vojvodina since 1989, contributed to the increase of the significance of migration component in population dynamics, regarding the fact that it mostly represents the crucial factor of population in-crease. In that sense, contribution of refugees to the values of mechanical inflow of population is ascertained. Having in mind the differentiation of municipalities according to the socio-economic characteristics of population, the paper gives the analysis of influence of refugees on the changes of these structures. The study encompasses economic and educational structure of population. The structure of refugee population by their economic activity also shows the extent of economic adaptation of refugees, as a very important factor in the process of their integration.

Simultaneous Growth

This paper first proposes a nonlinear dynamic migration model that describes the population dynamics of cities in a region. Second, by use of this model, several theorems are proved about the conditions necessary for (1) a state of simultaneous growth (that is, when the population of every city in a region increases simultaneously), and (2) a state of proportional growth (that is, when every city's proportion of the total population remains the same over time). Third, based upon the data analysis of interprefectural migration flows in Japan in 1970, some empirical implications of these theorems are considered.

The Media

Indigenous peoples in the Philippines have rarely been covered by the mainstream media, despite comprising 20 percent of the country’s total population. Lacking access to the media due to various constraints, they have had limited opportunities to create content themselves. But the emergence of the Internet, particularly blogs, is now providing members of indigenous communities with the much-needed space for self-expression. More particularly, several indigenous groups in North Luzon, collectively known as Igorots, are using blogs more extensively to re-construct and re-present their ethnic identity in cyberspace. For this paper, I shall describe how a group of Igorot bloggers protested about a controversial Igorot statue and how this eventually led to its removal.

Agricultural Experiment

The effect of planting date, year and pigeon pea line on the population fluctuations of phytoparasitic nematodes associated with pigeon pea was evaluated. Plots were established at the Isabela Agricultural Experiment Station between 1992 and 1994. The pigeon pea lines evaluated were 1-8-2, 1-13, 1-58-1, 1-58-3 y 11-56. Although some differences in the levels of nematode population were observed among years and lines, the maximum population levels were observed from May to July, and the minimum levels from February to April. These levels were more affected by the year than by the pigeon pea line. For each particular year, the maximum or minimum population growth consistently occurred at the same planting date, except in 1994 when the minima populations were erratic. Statistical analysis showed a significant three-way interaction between planting date, pigeon pea line and year, both for Rotylenchulus reniformis and for the total population (R. reniformis, Helicotylenchus sp. and Pratylenchus sp.). For this interaction the most influential factor was year, because the rainfall periods were different over three years. There was a positive correlation between precipitation and both the reniform nematode population and the total population, thus indicating that drastic changes in precipitation, such as those occurring in 1993 and 1994, may significantly affect the population dynamics of phytoparasitic nematodes associated with pigeon pea.
