The Amazon basin is a key supplier of wild freshwater fishes to the multi-billion US$ global aquarium market, yet limited information exists on the organization of the regional trade, its importance to local economies or conservation impacts. Through field interviews and review of government statistics, this paper describes the state of the industry in Peru, reporting on the scale and value of the trade, the nature of the fishery and the characteristics and roles of key actors in regional supply networks. An economically important industry is revealed, with 28 firms officially exporting over nine million fishes worth US$ 2.5 million to 24 countries in 2001, and involving fish species from 36 families transported from rainforest catchments up to 1100 km distant from the export centre of Iquitos. Most fish are however collected close to the city, with 10 species representing >70% of trade volume. Some 10 000 people earn income from the trade, among them many rural poor who depend on aquarium fish collection as a primary or supplementary source of cash income. The industry is currently undergoing an important transition towards supplying new Asian and European markets, increasing exports of species biologically unsuited to heavy exploitation as a result, and highlighting the conservation need for improved knowledge and management of the trade in Amazonia.

Understanding the effects of metal contamination in the Amazon basin is important because of the potential impact on this region of high biodiversity. In addition, the significance of fish as the primary source of protein for the local human population (living either alongside the Amazon River or in the city of Manaus) highlights the need for information on the metal transfer through the food chain. Bioaccumulation of metals in fish can occur at significant rates through the dietary route, without necessarily resulting in death of the organism. The goal of this work was to expose an economic relevant species from the Amazon basin (tambaqui, Colossoma macropomum) to dietary cadmium (Cd) at concentrations of 0, 50, 100, 200, and 400 µg.g-1 dry food. Fish were sampled on days 15, 30, and 45 of the feeding trials. Tissues were collected for analysis of Cd concentration using graphite furnace atomic absorption spectrophotometry. Cd accumulation in the tissues occurred in the following order: kidney > liver > gills > muscle. Relative to other freshwater fish (e.g., rainbow trout, tilapia), tambaqui accumulated remarkably high levels of Cd in their tissues. Although Cd is known to affect Ca2+ homeostasis, no mortality or growth impairment occurred during feeding trials.

The drinking water quality is associated with the conditions of the water supply networks, the pollution and the contamination of groundwater with pollutants of both anthropogenic and natural origin. In this study, water samples were taken from four different waterworks in Tunceli, Turkey and heavy metals concentrations (As, Cu, Cd, Cr, Pb, Ni and Hg) were measured. Four sampling sites were pre-defined in different locations of the city. The obtained results showed that, the heavy metals concentrations in water samples did not exceed the values of WHO (World Health Organization), EC (Europe Community), EPA (Environment Protection Agency) and TSE-266 (Turkish Standard) guidelines.

Abstract The work involves the realization of a GIS model that includes both information on real estate cadastre and water supply networks. This shows the stages of making such a model, starting from field measurements, to structuring the database and custom layouts. In the study, the distribution pipelines equipped with fire hydrants and the existing building types in the area were considered as the main elements. Buildings were classified according to importance, height, destination, mapping indexes, etc. and have been integrated into the GIS model. GIS programs aim at specifying as much as possible the textual data attached to perform complex analyzes. Autocad and ArcMap programs allow you to get thematic maps on building types, pipeline network analysis on which hydrants are located, and how to protect firewalls. The study model was developed only for a sector in the city of Iaşi, but it can be extended to an application that can be used in other urban areas for the purpose of being used by the water-channel directorate, the intervention teams, the public administration local, etc.

The aim of this paper is to examine the relationship between supply network position and firm performance. A-share manufacturing companies listed from 2013 to 2015 are chosen as the initial samples, and large sample supply networks are constructed with relational embeddedness and structural embeddedness. The location of supply network is depicted by network centrality and structural hole with social network analysis, and the influence of supply network position on the corporate performance is examined with multiple OLS regression analysis. This paper observes that a firms’ supply network position is an important factor affecting its performance. The higher the network centrality is, the richer the structural holes are, and the worse the company’s performance is. The results suggest that firms that have a high level of centrality or rich structural holes in their supply networks will gain limited information, resource and control benefits and face great business risks that may negatively influence their performance.

Background Body-mass index (BMI) and blood pressure (BP) levels are rising in sub-Saharan African cities, particularly among women. However, there is very limited information on how much they vary within cities, which could inform targeted and equitable health policies. Our study aimed to analyse spatial variations in BMI and BP for adult women at the small area level in the city of Accra, Ghana. Methods and findings We combined a representative survey of adult women’s health in Accra, Ghana (2008 to 2009) with a 10% random sample of the national census (2010). We applied a hierarchical model with a spatial term to estimate the associations of BMI and systolic blood pressure (SBP) and diastolic blood pressure (DBP) with demographic, socioeconomic, behavioural, and environmental factors. We then used the model to estimate BMI and BP for all women in the census in Accra and calculated mean BMI, SBP, and DBP for each enumeration area (EA). BMI and/or BP were positively associated with age, ethnicity (Ga), being currently married, and religion (Muslim) as their 95% credible intervals (95% CrIs) did not include zero, while BP was also negatively associated with literacy and physical activity. BMI and BP had opposite associations with socioeconomic status (SES) and alcohol consumption. In 2010, 26% of women aged 18 and older had obesity (BMI ≥ 30 kg/m2), and 21% had uncontrolled hypertension (SBP ≥ 140 and/or DBP ≥ 90 mm Hg). The differences in mean BMI and BP between EAs at the 10th and 90th percentiles were 2.7 kg/m2 (BMI) and in BP 7.9 mm Hg (SBP) and 4.8 mm Hg (DBP). BMI was generally higher in the more affluent eastern parts of Accra, and BP was higher in the western part of the city. A limitation of our study was that the 2010 census dataset used for predicting small area variations is potentially outdated; the results should be updated when the next census data are available, to the contemporary population, and changes over time should be evaluated. Conclusions We observed that variation of BMI and BP across neighbourhoods within Accra was almost as large as variation across countries among women globally. Localised measures are needed to address this unequal public health challenge in Accra.

Since the first attempts by states to use law to regulate armed conflict, legal constraints have often failed to protect civilians from the adverse effects of war. Advances in military technology have usually not improved this situation and have instead made law even more distant and less relevant to the suffering of civilians in wartime. The massive, indiscriminate incendiary bombing campaigns against major urban areas in World War II spoke volumes about the irrelevance of fundamental legal principles and rules designed to protect civilian populations in wartime. Law and lawyers were in fact far removed, physically and operationally, from the cockpits of the United States bombers flying over Tokyo, whose aircrews were focused on surviving their missions. They struggled with limited information about their assigned targets and conducted their operations with rudimentary preflight instructions that directed them, for example, to avoid destroying the palace of the Japanese emperor but left them free to submerge entire residential areas of the city in a sea of flames.

Abstract In 1751 Pope Benedict XIV made a donation of Amazonian objects to the Istituto delle Scienze in Bologna, a scientific academy located in the city of his birth. This article reconstructs the history of this group of objects back to its origins in the Jesuit missions of the upper Amazon basin, by presenting and examining new documentary evidence. The encounter between a Jesuit missionary and Pope Benedict XIV is analysed in the context of the early modern reception of the New World and its peoples in Catholic Europe. Finally, an overview is presented of the items in this collection, which represent some of the scarcest and oldest known examples of native material culture from the region.

Purpose The purpose of this paper is to figure out the impacts of soft innovation in the city hotels in general, whereas the focus is on figuring out if there exists a difference in vitality on the components of soft innovation among the hotel categories, as 4 stars, 5 stars and boutique hotels in Izmir, Turkey. Design/methodology/approach The first part is related to a detailed literature review on the soft innovation components as color, sound, light, scent and decoration. Literature review is followed by a qualitative research where expert information on the research topic is collected. Judgmental sampling is used to identify experts’ views where in-depth semi-structured interviews are conducted with 12 hotel managers in Izmir city. The soft innovation hotel application areas taken into consideration are: lobby and reception, rooms, restaurant, bar and ballroom areas, meeting and congress halls, SPA and pools, gardens and landscape and other exterior hotel architecture. Findings The findings of the research reveal the sample hotel managers’ views as all the soft innovation applications are important for all city hotels regardless of their category, meaning that soft innovation may lead to better marketing results. Thus, according to hotel managers, soft innovation offerings have a potential for better customer satisfaction as positive feedback. However, the vitality degree among components changes according to the hotel’s category. For boutique hotels the most important component is found to be the decoration of the hotel, whereas for 4 stars hotels it is light and for 5 stars hotels it is scent. Research limitations/implications The results of this study give relatively limited information because only managers’ point of view are shown. In the research, customers’ perceptions on soft innovation based interviews with the top management of the hotels studied takes place, indicating which may not be the case to reflect the real perception of customers. Therefore, for further researches, it is recommended for the other researches to take into consideration of customers’ point of views as well. Also, time limitation, sample size and application of only qualitative research may be stated as the limitations for this study. Quantitative research applies to customers on the same topic and problem statement is recommended for further studies related to city hotels’ soft innovation applications. Practical implications Motivation of this study is to understand how soft innovation can change hotels’ atmosphere and make it more attractive from the managers’ perceptions. According to hotel managers’ views, soft innovation applications may lead to higher customer satisfaction, but the level of investment among the components may change according to the city hotel’s category. Research implications indicate that hotel managers may optimize the effectiveness of their soft innovation efforts by taking into consideration their hotel type, application areas and innovation category as decoration, color, scent, sound and light. According to hotel managers, decoration-related soft innovation is more important to boutique hotels, lighting-related soft innovation is an effective investment for 4 stars hotels and scent-related soft innovation is a suitable investment for 5 stars hotels. Originality/value The originality of the study lies in the analysis of the components of soft innovation as a means for effective city hotel marketing and innovative management applications. Though it is a very suitable industry for implementation, improvement and development, there are limited studies on soft innovation applications in the hotel industry.

The article contributes to the historiography of the Czechoslovak communist dictatorship. The Communist takeover and stabilization of the regime were connected with various kinds of oppression including political trials. The biggest political trial in that time was that with the female politician Milada Horáková and the twelve members of her resistance group. This trial was followed by dozens of smaller local trials around the country, accusing 627 people altogether. While the main trial was carried publicly and was used extensively in the state’s propaganda, the local trials remain almost forgotten and outside the interest of Czech public. This paper will focus on one of them and its impact on my narrator and his family.Antonín Městecký jr. was a child when his father Antonín Městecký was imprisoned for 11 years after a local show trial in the city of Hradec Králové in East Bohemia. The imprisonment of his father was his strongest childhood experience; when his father returned home, the son was already an adult and they both kept silent about the traumatic past. They never discussed what really happened in the time of the father’s imprisonment, creating a severe trauma for the son. How can the turning point in someone’s life be remembered if we have only limited information?Using the methods of oral history, this paper explores how Mr. Městecký tries to deal with this gap in his family’s history by extending his childhood memories with information told to him by members of his father’s resistance group or found in books and archives. In the methodology, I will also reflect on how sharing his story with me constituted bridging the gap. His narrative contains rich accounts of life and survival as well as interesting moments and silences, revealing the complexities of trauma narratives and their effect on the descendants of former political prisoners.
