With the growth in water demand worldwide, cities are experiencing increasing difficulties to guarantee the public supply of drinking water. Therefore, the search for alternatives that replace the available sources needs to be disseminated. An alternative to reduce the demand for drinking water is to use the Rainwater harvesting system. This work analyzes the feasibility of implementing a system for capturing, storing, and distributing rainwater for non-drinking purposes in three standard projects of the National Fund for the Development of Education in three locations in the state of Pernambuco: Recife, Caruaru, and Petrolina. To achieve this objective, local rainfall data, the catchment area used and the demand for non-drinking water in the building were analyzed. Then, sizing calculations of the storage reservoir were performed by different methods. The time for return on investment was considered satisfactory for all types located in Recife and for the 1-room type in Caruaru and Petrolina, considering the benefit from the system in the long term. Therefore, the typologies of 6 and 12 rooms in Caruaru and Petrolina were excluded since they had a return time of more than 24 years. The advantages are not only financial, but also environmental, cultural, and educational.

Information Technology Outsourcing (ITO) has generated considerable interest within Information Systems (IS) research as a consequence of its benefits in terms of cost efficiency and freedom to focus on core capabilities. This study covers the area of ITO in the public sector, specifically, in Swedish Municipalities where ITO has become a mainstream strategy. The influential ITO factors of the post-contract stage of an ITO relationship are examined and debated in light of existent research literature. The research is based on a case study of a Swedish Municipality and a direct IT vendor. A thematic analysis brings light upon three new ITO influential factors which are: (1) mutual understanding and long-term engagement; (2) Multi-sourcing, and (3) Communication between Municipalities, together with other seven factors present in the research literature that have an influence on the ITO relationship. The findings of this study can support ITO decision-makers from Swedish municipalities in improving the ITO relationship between their organizations and IT vendors.

La baja disponibilidad de agua potable de buena calidad puede ser complementada con agua proveniente de la lluvia, si esta última es recolectada en cantidad suficiente para cubrir la demanda, aprovechándose esta combinación para resolver el problema de abastecimiento, todo esto sujeto a restricciones de inversión. El presente trabajo tiene por objetivo presentar un análisis de los sistemas de captación de agua de lluvia existentes en la zona limítrofe entre los estados mexicanos de Quintana Roo y Campeche para estimar los montos de inversión máxima que justifiquen un proyecto de mejora en la disponibilidad de agua de lluvia. En esta investigación se identificó el nivel de aprovechamiento y los requerimientos de los sistemas de captación de agua pluvial en techos (SCAPT) y se determinó el monto de inversión máxima para solucionar esta situación problemática. Los resultados muestran que los SCAPT no se aprovechan debido a limitaciones o subutilización en la superficie de captación y/o capacidad de almacenamiento, por lo que se recurre al suministro de agua en pipas. Se concluye que se puede sustituir el acarreo en pipas por agua de lluvia con un adecuado dimensionamiento de la superficie y el volumen de captación, asegurando el consumo de agua mínimo recomendado, con una inversión menor de la que se requeriría para la implementación de un sistema de abastecimiento de agua convencional.   Low availability of good quality drinking water can be complemented with rainwater, if the latter is collected in sufficient quantity to cover the demand, taking advantage of this combination to solve the supply problem, all of this subject to investment restrictions. The present work aims to present an analysis of the existing rainwater harvesting (RWH) systems in the border area between the Mexican states of Quintana Roo and Campeche to estimate the maximum investment amount that justifies a project to improve rainwater availability. In this research, the use level and the requirements of rooftop rainwater harvesting (RTRWH) systems were identified and the maximum investment amount needed to solve this problematic situation was determined. Results show that RTRWH systems are not used due to insufficient or underutilized catchment area and / or storage capacity, so water is supplied in tankers. It is concluded that transport in tankers can be replaced by RTRWH with an adequate dimensioning of surface and catchment volume, ensuring the minimum recommended water supply, with a lower investment than that required for the implementation of a conventional water supply system.

Purpose The purpose of this paper is to investigate the effects a lean initiative has on the health-related quality management (QM) values, “Leadership Commitment” and “Participation of Everybody,” as well as on perceived co-worker health in the public sector. Design/methodology/approach A case study was carried out at a municipal division that had been working with lean for approximately 18 months. A questionnaire was used to measure the effect on health-related QM values both before and after the initial 18 month period. Documents from the intended lean implementation were studied at the starting point and after 18 months; this was followed up by examining new documents. The results from the questionnaires were analyzed using SPSS and the documents were analyzed by means of document comparisons and consensus discussion in the research group. Findings The effects on the health-related QM values; “Leadership Commitment” and “Participation of everybody” in this study showed that the values still permeated the organization to a relatively high extent after 18 months but that no statistical differences can be shown between the two measurement points. When measuring what effects a lean initiative has on values, a period of 18 months might be too short, if significance changes are expected. None the less, the results can be a way of monitoring the development of these softer values. Something that is equally important is to see if there have been any major changes, as a way of keeping the work with building a new culture alive and in focus. The results strengthen the assumption that a long-term mindset is needed when QM initiatives such as lean are applied within an organization especially when changes to values and workplaces are expected. Originality/value This study has further explored the QM in relation to lean in the respect of how the QM values “Leadership commitment” and “Participation of Everybody” are effected by a lean initiative.

Environmental Compartments

The use of marginal water, such as reclaimed wastewater or effluent, for irrigation can reduce the pressure on existing freshwater resources. However, this can cause contaminants to accumulate in compartments such as the soil, crop, air, surface- and groundwater, which may harm the public health and the environment. Environmental quality standards for these compartments are generally considered separately. However, the compartments are related to each other by the fluxes between them, and the concept of sustainability should hold for all compartments simultaneously. An integrated approach is therefore required for the sustainability assessment of irrigation with marginal water. Since such an approach has not been provided yet, we develop an integrated framework in this study. We provide sustainability indicators by comparing the long-term contaminant concentration and fluxes with quality standards for each environmental compartment. These indicators give comprehensible information on which contaminants will cause problems, which environmental compartments are threatened, and on what timescale this will occur. This allows for the prioritization of mitigation and preventive measures for better sustainability management. We illustrate the use of the framework by means of a case study.

Urban Brownfields

The linking (in terms of functional use) of brownfield sites with creative spaces is a frequently encountered phenomenon in western European, post-communist, and industrialized countries in general and is viewed as a way of revitalizing, repurposing, or simply making temporary use of them. It may also be seen in the municipality of Timișoara in Romania, where 12 creative spaces, each involving one or more kinds of functionalities (coworking space, maker space, community space, event space, incubator), are operating on such sites. A content analysis of interviews with those in charge of these 12 creative spaces brought to light, on the one hand, the opportunities represented by the existence of derelict industrial spaces, as represented by their large size, low rents, and innate flexibility, but on the other the reality of a number of long-term constraints on the use of these spaces, given the financial instability of cultural operators, the limited numbers of the public who are interested in creative activities of this kind, and, most seriously, the development pressure exerted by some real-estate developers on derelict industrial spaces.

PurposeThe purpose of this paper is to report on a three-year case study of the extent with which altmetrics compare to traditional metrics in certain subject areas for selected departments at the University of Cincinnati, College of Medicine (COM). Design/methodology/approachA three-year analysis of peer-reviewed papers and invited editorials from 2009 to 2013 written by tenure-track faculty from 20 COM departments was done to explore what subject areas received the highest altmetric scores. Research output was searched in PubMed; articles were quantified by subject area, times cited in Scopus, and its altmetric score over each of three successive years. FindingsThe topics of the highest scored altmetric papers (n = 40) sample focused on stroke, obesity, and diabetes for all three years. Analysis of high initial altmetric scores over the course of the three years shifted from a possible predictor of future impact in the second year to no indicator of long-term interest in the scientific community as the public interest waned over time. Research limitations/implicationsThe authors used Scopus Times Cited and Altmetrics.com to gather data. Originality/valueInitially assessed a total of 3,678 unique publications and worked with the 40 highest altmetric scores in subsequent years. Data showed that subjects of interest to the public receive the highest altmetric scores and the topic areas did not change over the course of the study. These initially high altmetric scores do not indicate long-term interest by the scientific community.

The El Rodadero, 5-6 km southwest of Santa Marta, was a lonely sand beach up to 1960 with dispersed fishing huts. From 1965 it developed more and more to the seasonally prefered bathing place of Colombia on the Caribbean Sea. Both, the Colombian press and the public opinion regard the Rodadero as "centro turístico de Colombia" or "la perla del Caribe"; it is compared with the international luxury beach towns in the circum-caribbean region (Acapulco, Miami etc.). - As there exist however strict arguments against this statement, a socio-economic study was carried out about he Rodadero in 1969/70. As a result the following characterization is possible: a constructionally unorganic, periodically frequented bathing-(vacation~)place (max. 3 months/ year: middle of December up to the end of January, the Easter week, 4 to 5 weeks in June/July according to the main school holidays) of national importance as well as of a certain value to the weekend holidays-traffic coming from the region of Barranquilla. Apartment houses with vacation flats belonging to rich Colombians are clearly dominating compared with hotels, motels etc. On the whole the infrastructure is not sufficient, especially the public supply (drinking-water, sewage, electricity etc.).
