Abstract Stormwater runoff containing various pollutants exerts adverse effects on receiving water bodies and deteriorates the urban aquatic environment. Although numerous studies have been conducted on runoff pollution, research comparing its characteristics in cities with those in towns is rare in the literature. To close this gap, the present study was conducted. The outflow concentration and peak value of N in the town were higher than those in the city in most conditions (at 75% and 67%, respectively). The second peak value of P in the town was higher and occurred earlier than the city. EMCs of TN and DTN in the town were 20%–60% (10%–50%) higher than those in the city. DTP accounted for 76.9%–83.3% of the total P (TP) in the town, which was generally higher than the city values of 50%–87.5%. According to our results, road runoff in the town contributed more to urban aquatic pollution, thus further research should concentrate on this particular type of runoff.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

Dominique Iogna-Prat’s latest book, Cité de Dieu, cité des hommes. L’Église et l’architecture de la société, 1200–1500, follows on both intellectually and chronologically from La Maison Dieu. Une histoire monumentale de l’Église au Moyen Âge (v. 800–v. 1200). It presents an essay on the emergence of the town as a symbolic and political figure of society (the “city of man”) between 1200 and 1700, and on the effects of this development on the Church, which had held this function before 1200. This feeds into an ambitious reflection on the origins of modernity, seeking to move beyond the impasse of political philosophy—too quick to ignore the medieval centuries and the Scholastic moment—and to relativize the effacement of the institutional Church from the Renaissance on. In so doing, it rejects the binary opposition between the Church and the state, proposes a new periodization of the “transition to modernity,” and underlines the importance of spatial issues (mainly in terms of representation). This last element inscribes the book in the current of French historiography that for more than a decade has sought to reintroduce the question of space at the heart of social and political history. Iogna-Prat’s stimulating demonstration nevertheless raises some questions, notably relating to the effects of the Protestant Reformation, the increasing power of states, and the process of “secularization.” Above all, it raises the issue of how a logic of the polarization of space was articulated with one of territorialization in the practices of government and the structuring of society—two logics that were promoted by the ecclesial institution even before states themselves.

In the discussion of Greek dramatic origins, a curious passage of Apuleius has never, so far as I know, been mentioned.In the second book of the Metamorphoses the hero Lucius describes a feast given at Hypata in Thessaly by his rich relative Byrrhena. After the feast Byrrhena informs him that an annual festival, coeval with the city, will be celebrated next day—a joyous ceremony, unique in the world, in honour of the god Laughter. She wishes that he could invent some humorous freak for the occasion. Lucius promises to do his best. Being very drunk, he then bids Byrrhena good-night, and departs with his slave for the house of Milo, his miserly old host. A gust blows out their torch, and they get home with difficulty, arm in arm. There they find three large and lusty persone violently battering the door. Lucius has been warned by his mistress, Milo's slave Fotis, against certain young Mohawks of the town—‘uesana factio nobilissimorum iuuenum’—who think nothing of murdering rich strangers. He at once draws his sword, and one by one stabs all three. Fotis, roused by the noise, lets him in and he quickly falls asleep.

abstract On 28 July 1981 at 17:22 UTC, the Kerman province of southern Iran was shaken by the largest and the most destructive earthquake in its history. Its surface-wave magnitude was about 7.2. The epicenter of the earthquake was located about 45 km southeast of the city of Kerman, the capital of the Kerman province. The shock killed nearly 3,000 people, left more than 31,000 homeless, and destroyed virtually all buildings in the epicentral region within a radius of 30 km. The hardest hit place was the town of Sirch where about 2,000 people died out of a population of 3,500. Surface fractures were observed in several areas, and the earthquake was apparently associated with a fresh surface normal faulting. The maximum vertical displacement was about 1 m. The maximum width of the fracture was 0.5 m. Also, extensive landsliding and numerous rockfalls were observed within the area of maximum damage. Most houses in the epicentral area are of adobe construction, made of sundried clay brick walls, and heavy domed roofs or vaults with clay or mud mortar. Most casualties were due to the collapse of these adobe buildings. However, the performance of unreinforced or reinforced brick buildings, historical monuments, steel buildings, and other types of structures during the earthquake is also discussed in this paper.

The vertical and diurnal variation of nitrogen and phosphorus forms, as well as that of soluble reactive silica (SRS), were studied in four sampling days at Garças reservoir, a shallow tropical one located in the city of São Paulo, in southeastern Brazil. Except for N-NH4, all other inorganic forms of nitrogen (N-NO2, N-NO3, and total N) demonstrated decreased concentrations toward the bottom of reservoir. Similarly, all showed significant diurnal differences on every sampling day, with increased values during the night due to absence of photosynthetic assimilation during that period. In the sampling days, these forms decreased on the spring sampling day due to the bloom of Microcystis registered during this period of the year. All three forms of phosphorus (SRP, particulate P, and total P) showed significant vertical variation, except on the fall sampling day. On the summer sampling day there was an increase of both total P and particulate P, the latter because it constitutes more than 70% of the total P during all sampling days. Hourly phosphorus variation was significant during all sampling days, except for the summer one. The SRS vertical variation was significant during all sampling days, except for that in the spring. It was also different hourly on sampling days.

The remainance and development in the market depend, among other factors, on the quality of sold products or provided services, which is a situation of concern in sectors such as tourism where globalization demands first level services, as is the case in the city of Campeche, where businessmen are investing in hotel infrastructure according to the colonial characteristics of the town. The research´s objective is to identify the incidence of leadership in the quality of services under the perception of hotel managers as responsible for the operability results. This research is a descriptive type with non-experimental transversal design, with a enumerated population; the results obtained through the quality and leadership indexes indicate that, contrary to expectations, managers consider that the provided services don´t have an adequate level of quality, and the design of new strategies is needed to improve the processes under the transformational leadership which must face problems with opportunity in order to innovate in the services of the market where they participate.

Introduction. In 1275, two drafts of town law of Freiburg im Breisgau were created. This article presents an analysis of one of these texts, namely the short draft. Methods and materials. The main research method is comparative historical analysis. The contents of two charters are compared, namely the 1218 Rodel draft and the short draft of 1275. Analysis. There are 6 thematic clusters uniting the laws by branches of law: 1) privileges of citizens and rights of the Town Lord; 2) criminal procedure law; 3) civil law; 4) town administration; 5) trade law; 6) various laws. The first part of the laws from the short draft is a translation of the Rodelian laws, the second one represents reformulated Rodelian norms, while the last one contains new laws in the legislation of Freiburg. Results. Though the document did not become an official town charter, it manifested the changes in the town law of the 13th century, compared to the previous 1218 Town Charter. In addition, the laws in the draft reflected the political struggle for power between the Town Lord of Freiburg, the City Council of 24 and the town community. The Town Lord regained his previously lost rights, in particular the legislative initiative. However, at the same time, the short draft significantly limited Lord’s arbitrariness towards the property of citizens as well as Freiburg citizens themselves. According to the short draft, the City Council of 24 strengthened and expanded its power in the town, becoming a full-fledged legislative and executive body of the town administration. The town community, on the other hand, was losing its privileges and rights, for example, it lost the opportunity to elect some of the civil servants and members of the Council of 24.

Over the last fifty years, institutions of higher education have served as anchor institutions in cities’ broader neoliberal efforts to generate new economic sectors, attract the creative class, and build amenities that stimulate market-oriented redevelopment. These activities, combined with universities’ own neoliberal restructuring, including diminishing housing support for students and staff, have contributed to gentrification and displacement in neighborhoods surrounding universities, creating the context for interrelated struggles for the right to the city and the right to the university. Using Temple University in Philadelphia, and University of California Santa Cruz as case studies we examine how students, faculty, and other university actors are joining with organizations and movements in surrounding communities to resist restructuring and displacement. In doing so, these emerging coalitions are transcending the more divisive town/gown narrative, forging new solidarities that are reimagining more just and equitable futures for both the city and the university.
