Using new data on roll-call voting of US state legislators and public opinion in their districts, we explain how ideological polarization of voters within districts can lead to legislative polarization. In so-called “moderate” districts that switch hands between parties, legislative behavior is shaped by the fact that voters are often quite heterogeneous: the ideological distance between Democrats and Republicans within these districts is often greater than the distance between liberal cities and conservative rural areas. We root this intuition in a formal model that associates intradistrict ideological heterogeneity with uncertainty about the ideological location of the median voter. We then demonstrate that among districts with similar median voter ideologies, the difference in legislative behavior between Democratic and Republican state legislators is greater in more ideologically heterogeneous districts. Our findings suggest that accounting for the subtleties of political geography can help explain the coexistence of polarized legislators and a mass public that appears to contain many moderates.

Roll-call votes provide scholars with the opportunity to measure many quantities of interest. However, the usefulness of the roll-call sample depends on the population it is intended to represent. After laying out why understanding the sample properties of the roll-call record is important, we catalogue voting procedures for 145 legislative chambers, finding that roll calls are typically discretionary. We then consider two arguments for discounting the potential problem: (a) roll calls are ubiquitous, especially where the threshold for invoking them is low or (b) the strategic incentives behind requests are sufficiently benign so as to generate representative samples. We address the first defense with novel empirical evidence regarding roll-call prevalence and the second with an original formal model of the position-taking argument for roll-call vote requests. Both our empirical and theoretical results confirm that inattention to vote method selection should broadly be considered an issue for the study of legislative behavior.

Previous research has noted the transformation of the American parties since the 1970s, as exhibited in their increased ideological polarization and transformation on social issues like civil rights, abortion, and the environment. We contribute to the literature on party change by theoretically stressing the decentralized and individualistic nature of American parties, while using a measure of party change that is based on legislative behavior beyond roll call voting. Our paper uses social network analysis to analyze the parties from the 93rd to 110th Congresses, utilizing bill cosponsorship to define connections between members. Our analysis illustrates how the core of the party, that is, who are most central in the cosponsorship network, has changed over time. We find evidence that party centrality influenced retirement decisions, thereby reinforcing and contributing to party change.

Research on stress related to the COVID-19 pandemic has been dominated by the cases of healthcare workers, students, patients, and their stress during the COVID-19 pandemic. This study examined the relationship between the amount of stress change under the COVID-19 pandemic and demographic factors (age, sex, occupation, etc.) in residents of a large city and a rural area of Japan. A total of 1331 valid responses were received in June 2020 from residents of Tokyo, Osaka, and Nagano registered with a private research firm. We were able to identify 15 statistically significant variables out of 36 explanatory variables, which explained the significant increase in stress compared to the pre-pandemic period. Multiple-factor analysis showed that the relationship with people is a more significant explanatory variable for the level of increase in stress than the difference in environment between big cities (Tokyo, Osaka) and rural areas (Nagano), the type of housing, and the decrease in income compared to the pre-pandemic period.

Abstract This study is focused on the changing of areas of water bodies in selected villages of the Pilsen Region (Czechia). We researched several different types of rural settlements and three time horizons with the help of old maps, orthophoto maps and GIS tools. To capture the influence of their location within the urban system, we chose 15 places from four categories (inner suburban area, outside suburban area, rural area, periphery rural area) depending on their distance to the core of the Pilsen agglomeration. There is no significant change in the amount of water bodies between the first reference period (1838-1839) and the second period (1957-1963) in the selected settlements. However, the third period (2013-2015) is characterized by the emergence of a large number of small water bodies - swimming pools and garden ponds. Based on the results of our research we identified the declining importance of public water bodies in some of the settlements. However, we have identified a notable prevalence of garden ponds which have a more positive ecological impact than pools. The proportion of private water bodies (covered and uncovered pools and garden ponds) in the total area of water bodies in the rural settlements in most cases is less than 20%, in the suburban settlements up to 100%. Peripheral settlements have a below-average share of these water bodies. The difference between the number of pools in different settlements is related to the proportion of newly built houses there. Although there are relatively fewer pools in rural settlements, the difference compared to the situation in suburban settlements is not pronounced due to the change in lifestyle in rural areas and the change in functions of some villages to recreational areas. Influence of pools on water consumption is dependent on the individual exchange technology of water in swimming pools. Filling of the pool before the season can overload the capacity of the local water supply.

Violence against women is linked to their disadvantaged position in the society. It is rooted in unequal power relationships between men and women in society and is a global problem which is not limited to a specific group of women in society. An adolescent girl’s life is often accustomed to the likelihood of violence, and acts of violence exert additional power over girls because the stigma of violence often attaches more to a girl than to the  perpetrator. The experience of violence is distressing at the individual emotional and physical level. The field of research and programmes for adolescent girls has traditionally focused on sexuality, reproductive health, and behaviour, neglecting the broader social issues that underpin adolescent girls’ human rights, overall development, health, and well-being. This paper is an endeavour to address the understated or disguised form of violence which the adolescent girls experience within the social contexts. The parameters exposed under this research had been ignored to a large extent when it comes to studying the dimension of violence under the social domain. Hence, the researchers attempted to explore this camouflaged form of violence and discovered some specific parameters such as: Diminished Self Worth and Esteem, Verbal Abuse, Menstruation Taboo and Social Rigidity, Negligence of Medical and Health Facilities and Complexion- A Prime Parameter for Judging Beauty. The study was conducted in the districts of Haryana (India) where personal interviews were taken from both urban and rural adolescent girls (aged 13 to 19 years) based on  a structured interview schedule. The results revealed that the adolescent girls, both in urban as well as rural areas were quite affected with the above mentioned issues. In urban areas, however, due to the higher literacy rate, which resulted in more rational thinking, the magnitude was comparatively smaller, but the difference was still negligible.

Abstract Background: Multimorbidity is defined as the co-occurrence of two or more than two diseases in the same person. With rising longevity, multimorbidity has become a prominent concern among the older population. Evidence from both developed and developing countries shows that older people are at much higher risk of multimorbidity, however, urban-rural differential remained scarce. Therefore, this study examines urban-rural differential in multimorbidity among older adults by decomposing the risk factors of multimorbidity and identifying the covariates that contributed to the change in multimorbidity.Methods: The study utilized information from 31,464 older adults (rural-20,725 and urban-10,739) aged 60 years and above from the recent release of the Longitudinal Ageing Study in India (LASI) wave 1 data. Descriptive, bivariate, and multivariate decomposition analysis techniques were used.Results: Overall, significant urban-rural differences were found in the prevalence of multimorbidity among older adults (difference: 16.3; p<0.001). Moreover, obese/overweight and high-risk waist circumference were found to narrow the difference in the prevalence of multimorbidity among older adults between urban and rural areas by 8% and 9.1%, respectively.Conclusion: There is a need to substantially increase the public sector investment in healthcare to address the multimorbidity among older adults, more so in urban areas, without compromising the needs of older adults in rural areas.

Abstract. Riwidiharso E, Darsono, Setyowati EA, Pratiknyo H, Sudiana E, Santoso S, Yani E, Widhiono I. 2020. Prevalence and diversity of ectoparasites in scavenging chickens (Gallus domesticus) and their association to body weight. Biodiversitas 21: 3163-3169. Domestic chickens (Gallus domesticus) which are traditionally fed by scavenging on farms predispose them to ectoparasites infestation. In this study, a preliminary survey was conducted on the common ectoparasites on G. domesticus in the rural areas of Banyumas. The purposes of this study were to determine the diversity of ectoparasites, their prevalence, and their relationship to the chickens body weight. This research was conducted by the survey method from December 2019 to April 2020 in five villages around the city of Purwokerto, Banyumas District, Central Java, Indonesia viz., Kedungwuluh, Kedungwringin, Kutasari, Karangsalam, and Karanggintung. Data analysis was conducted by Shannon Wiener and Evenness indexes. Analysis of variance was used to calculate the difference in prevalence among sample locations. Regression correlation analysis was used to determine the relationship between prevalence and chicken body weight. The results showed that there were six ectoparasite species  i.e., Menopon gallinae, Menacanthus cornutus, Lipeurus caponis, Dermanysus gallinae, Megninia ginglymura, and Haemaphysallis sp. parasitizing G. domesticus. The number of ectoparasite individuals among locations was significantly different (F 5.59 < 32.45; p <0.05). The most number of ectoparasite was found in Karangsalam (272 individuals). The most prevalent ectoparasite was M. cornutus (45%), followed by L. caponis (40%), and the lowest was M. synglineura (25%). Ectoparasite prevalence was associated with chicken weight loss (r = 0.98). The prevalence of ectoparasite of domestic chickens farm in the Banyumas Regency is classified as low but has the potential to influence body weight.

Young generations are those who make lives livelier and happier, who design the future and make the change, the ones with full hope and enthusiasm to go further and make the impossible possible. As every country of Europe, Asia or America, Albania as well is surrounded by a very fruitful young ladies and gentlemen's. This paper aims to analyse the changes of the youth development in Albania during the transition period. The young development in Albania has faced many problems, such as the difference between the levels of development of the youths that live in the other cities of Albania with the ones of the capital. Rural areas and small towns are closed where a portion of youth in minor are totally dependent from family, and they are exactly that with their weak hands are inclined to do the heavy work to keep their family one more day alive. Youth at the opening of the borders, generally tended to leave towards legal immigration either as tourist or in illegal opportunities addressing major countries like Britain, Greece, Italy, Belgium etc. Albania needs to make arrangements which will be financed by businessmen, private universities in cooperation with the state to offer young people opportunities to work together and to be closer to each other and to show their skills in conversation competitions. At the same time the state has other open universities in backward areas which will provide young entrepreneurs' with more opportunities for young people to graduate and to serve different areas. Meanwhile, there is needed a strategy to separate the fields in which there is a need to have more expert in the field which is required to work also which would come more to help the country's economy with the addition of experts. Albania is a country blessed where high mountains finish in seas, where groundwater resources are numerous, and with a conductive climate to produce almost all kinds of fruits and where vegetation is very diverse. If the youth will be directed towards learning of foreign languages and in recognition of their territories, traditions and customs, thus, we would make a big step because tourism market is precisely the kind of market where young people will find themselves more comfortable than ever, where the labour force will be insufficient paid and where the demand for products would be required as the number of tourists would be great and just the requirements would change in terms of application areas during the summer as it would be for beaches and seasonal fruits, while during the winter for skiing and mountain tourism.

Introduction: The incidence of stroke is higher in rural areas. Hypertension is the leading risk factor for stroke, but the difference in systolic blood pressure (SBP) for those living in rural and urban areas is unknown. Hypothesis: We hypothesized that rural residence is associated with higher SBP levels, and this difference is modified by race, sex, and United States (US) division. Methods: We analyzed 26,113 participants enrolled in the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study, recruited between 2003 and 2007. Participants were grouped based on the Rural-Urban Commuting Area (RUCA) scheme into urban, large-rural, and small-isolated rural groups. Resting SBP was measured during the initial home visit. Differences in percentiles of SBP distribution were compared using multivariate models with adjustment for age, race, sex, and US Census Bureau division. Results: Of the participants, 20,976 (80.3%) were classified as urban, 3,020 (11.6%) as large-rural, and 2,137 (8.2%) as small-isolated rural, reflecting the distribution of the population. The large-rural group had a 0.09 mmHg higher mean SBP compared to the urban group (95% CI, 0.33 to 1.52 mmHg, p = 0.0023), but the difference in SBP at the 95th percentile between these groups was 3.23 mmHg (95% CI, 1.43 to 4.73 mmHg, p = 0.0006). A similar difference was present between the small-isolated rural and urban groups at the highest percentiles. No urban-rural interaction was observed by race, sex, or US division. However, large SBP differences were present between US divisions, especially at the highest percentiles. To illustrate, SBP at the 95th percentile was 9.51 mmHg higher in the East North Central division than in the Pacific (95% CI, 6.41 to 12.61 mmHg, p < 0.0001). Conclusions: Residence in a rural area is associated with higher SBP, with larger differences at the highest percentiles of distribution. SBP differences are present between US divisions, independent of urban-rural status.

More than half of the world’s population now live in cities, which are known to be heat islands. While daytime urban heat islands (UHIs) are traditionally thought to be the consequence of less evaporative cooling in cities, recent work sparks new debate, showing that geographic variations of daytime UHI intensity were largely explained by variations in the efficiency with which urban and rural areas convect heat from the land surface to the lower atmosphere. Here, we reconcile this debate by demonstrating that the difference between the recent finding and the traditional paradigm can be explained by the difference in the attribution methods. Using a new attribution method, we find that spatial variations of daytime UHI intensity are more controlled by variations in the capacity of urban and rural areas to evaporate water, suggesting that strategies enhancing the evaporation capability such as green infrastructure are effective ways to mitigate urban heat.
