Animal production in Tanzania grass swards fertilized with nitrogen
Canto, Marcos Weber do;Bona Filho, Amadeu;Moraes, Aníbal de;Hoeschl, André Ricardo;Gasparino, Eliane;
Revista Brasileira de Zootecnia , 2009, DOI: 10.1590/S1516-35982009000700003
Abstract: nitrogen (n) at 100, 200, 300, and 400 kg ha-1 was applied to tanzania grass swards to evaluate the animal response and relationships between sward characteristics and the performance of young nellore bulls (bos indicus) under continuous stocking. a completely randomized experimental design was used with two replications between 11 november 2001 and 15 april 2002 when the sward heights were maintained at 60 cm by using different stocking rates. the average daily gain (adg) (0.73 kg d-1) was not affected by n doses while the number of animal days ha-1 increased linearly from 515 to 1267. on the other hand, the linear increase in the animal yield was 399, 653, 755, and 895 kg ha-1 for n at 100, 200, 300, and 400 kg ha-1, respectively, while the ratio between the liveweight gain (kg) and n (kg ha-1) decreased. correlation coefficients between adg and herbage mass, green leaf mass, green herbage mass, proportion of green leaf and leaf:culm ratio were low and nonsignificant. under the conditions in northwestern paraná, the application of n to swards of tanzania grass is a management option for increasing beef cattle production.
Reliance, déliance, liance: emergenza di tre nozioni sociologiche
Marcel Bolle De Bal
m@gm@ , 2007,
Abstract: Michel Maffesoli, grande seguace, utilizzatore e diffusore della nozione di rileanza mi ha chiesto, come padrino della stessa, di redigere un articolo di riferimento concernente la genesi e il contenuto di questo concetto a causa dell’attenzione crescente. Ciò facendo, pensava non soltanto ai suoi colleghi sociologi, ma soprattutto ai suoi studenti e discepoli portati a ricorrere all’uso di questo termine relativamente nuovo nell’armamentario della lingua sociologica. è ben volentieri che rispondo al suo amichevole ed insistente invito. Tenuto conto dei molteplici scambi che ho avuto a questo proposito nel corso degli anni, reputo indispensabile legare l’analisi del concetto di rileanza a quella degli altri due che le sono ontologicamente legati: delianza e leanza . In realtà - ciò può constatarsi dalla lettura cronologica dei miei scritti sull’argomento - la ri-leanza suppone l’esistenza preliminare di una de-lianza e questa uno stato di pre-delianza che definiamo allora come il fenomeno di leanza , sequenza che tenterò di chiarire qui di seguito.
New Student Profiles: Creativity in Competent Digital Natives and Routine Experts
Aníbal de la Torre
Revista de Universidad y Sociedad del Conocimiento , 2009,
Abstract: Matters that until now were exclusive to pedagogic debate, such as teaching-learning models or the kinds of skills and abilities needed by the youth of today, have now entered a wider discussion arena, as it is society as a whole that expects professional and human profiles to be more adapted to current times. To achieve this, we should not assume that our youths possess some natural ability to act in the new technological environments, as it is probably their communicative needs that give rise to using these environments. Modest practical ideas and solid methodological referents are needed which will allow us to open up the limited world that is digitally evolving around our young people. The area of development they are about to enter has just started to shift towards globality and their responsibility as digitally-aware citizens is acquiring an importance still to be discovered but which we can no longer remain oblivious to.
The sacred, philosophical and sociological Janus
Essachess : Journal for Communication Studies , 2011,
Abstract: Symbolically, Janus, as the god of initiations, is supposed to be the Sacred's keeper. The Sacred, like Janus, has two faces : the religious and the non-religious one. The latter has a reconnecting function. As an illustration of its reality is presented its specific existence inside Free-masonry. Are successively analysed the relations between the Sacred and divinity, humanity, secret, profane and modern communication.
Telemedicine in interdisciplinary work practices: On an IT system that met the criteria for success set out by its sponsors, yet failed to become part of every-day clinical routines

Abstract: We evaluated a telecare service set up to reduce the workload of ophthalmologists. In this project, optometrists in 10 optical shops made digital images to detect patients with glaucoma which were further assessed by trained technicians in the hospital. Over a period of three years, we conducted interviews with the project team and the users about the workability of the system and its integration in practice. Beside the interviews, we analyzed record data to measure the quality of the images. We compared the qualitative accounts with these measurements.According to our measurements, the quality of the images was at least satisfactory in 90% of the cases, i.e. the images could be used to screen the patients – reducing the workload of the ophthalmologist considerably. However, both the ophthalmologist and the optometrists became increasingly dissatisfied respectively with the perceived quality of the pictures and the perceived workload.Through a detailed analysis of how the professionals discussed the quality of the pictures, we re-constructed how the notion of quality of the images and being a good professional were constructed and linked. The IT system transformed into a quality system and, at the same time, transformed the notions of being a good professional. While a continuous dialogue about the quality of the pictures became an emblem for the quality of care, this dialogue was hindered by the system and the way the care process was structured.To conceptualize what telemedicine does in interdisciplinary work practices, a fine-tuned analysis is needed to assess how IT systems re-shape the social relations between professional groups. Such transformations should not be exclusively attributed to the technology itself or to the professionals working with it. Instead we need to assess these technologies through an empirically grounded study of the sociotechnical functioning of telemedicine.Information systems can play a key role in care innovations including task rede

Databases as policy instruments. About extending networks as evidence-based policy
Antoinette de Bont, Herman Stoevelaar, Roland Bal
BMC Health Services Research , 2007, DOI: 10.1186/1472-6963-7-200
Abstract: We conducted three case studies to reconstruct the development and use of databases as policy instruments. Each database was intended to be employed to control the use of one particular pharmaceutical in the Netherlands (growth hormone, antiretroviral drugs for HIV and Taxol, respectively). We studied the archives of the Dutch Health Insurance Board, conducted in-depth interviews with key informants and organized two focus groups, all focused on the use of databases both in policy circles and in clinical practice.Our results demonstrate that policy makers hardly used the databases, neither for cost control nor for quality assurance. Further analysis revealed that these databases facilitated self-regulation and quality assurance by (national) bodies of professionals, resulting in restrictive prescription behavior amongst physicians.The databases fulfill control functions that were formerly located within the policy realm. The databases facilitate collaboration between policy makers and physicians, since they enable quality assurance by professionals. Delegating regulatory authority downwards into a network of physicians who control the use of pharmaceuticals seems to be a good alternative for centralized control on the basis of monitoring data.Several authors have stressed the need for improving evidence-based health policy [1-3]. One way of enabling truly evidence based policy is claimed to be the use of databases [4,5]. Where the results of clinical studies are lacking or are insufficient – for example in when there is uncertainty about the long-term effects of a specific technology – databases may be used to monitor the effectiveness and safety of using these technologies in clinical practice. In addition, monitoring can be used to produce data about the appropriateness of care and associated costs. In short, it is assumed that databases, particularly those linked to electronic medical records, would enable the long-term follow-up of patients, providing informatio

Abstract: the bivalve corbicula fluminea müller is recorded for the first time in colombia, in the national park isla de salamanca. this protected area includes freshwater channels and mixohaline lagoons influenced by waters of both the magdalena river and the caribbean sea. this exotic bivalve occurs locally in freshwater channels close to the magdalena river as well as in the latter, whereas another corbiculid native species, polymesoda solida, is commonly found in the mixohaline lagoons. densities of c. fluminea ranged from 10 to 100 ind/m2 along with low numbers of p. solida. lengths ranged form 10 to 43 mm in a predominant muddy substrate. local fishermen have stated that c. fluminea was established approximately in 1992; this clam is being artisanally exploited for human consumption along with p. solida, although fishery is mainly focused on the latter, due to its larger size.
