Realizar una revisi??n te??rica sobre las investigaciones m??s recientes de las actitudes en general y frente a los inmigrantes en particular. Realizar una evaluaci??n de las variables espec??ficas que influyen en las actitudes de los maestros y maestras en formaci??n y en ejercicio hacia la integraci??n escolar de inmigrantes extranjeros de la zona del Bierzo. Realizar un estudio comparativoentre las actitudes de los profesores y los futuros profesores. Extraer implicaciones y sugerencias sobre la intervenci??n psicoeducativa en relaci??n con la mejora de las actitudes hacia la integraci??n escolar de este tipo de alumnos. Profesores y maestros de todos los centros p??blicos y privados de niveles no universitarios del Bierzo. Cuestionario de informaciones generales y dos escalas de actitudes del profesorado hacia la integraci??n escolar de alumnos inmigrantes extranjeros, un instrumento escalar y de diferencial sem??ntico. El an??lisis de datos se realiz?? con los m??dulos del paquete estad??stico CSS. Las actitudes de los profesores y maestros en ejercicio respecto a la integraci??n de alumnos inmigrantes extranjeros en las aulas ordinarias son mayoritariamente positivas Existen variables que afectan a las actitudes de los mismos, consideran la necesidad de formaci??n e informaci??n en esa l??nea. Los alumnos de magisterio por el contrario, presentan una actitud mayoritariamente negativa debido a la influencia de los estereotipos y la falta de contacto real con las aulas. Las recomendaciones e implicaciones que se extraen son la necesidad de planificar una formaci??n espec??fica y planes de formaci??n en los propios centros, as?? como la consideraci??n de las actitudes de los profesores universitarios que forman a los futuros docentes. La formaci??n espec??fica de los equipos psicopedag??gicos ser??a necesaria como nucleo catalizador y dinamizador de la introducci??n de innovaciones exitosas que aumenten la motivaci??n del profesorado y que estos perciban el trabajo con alumnos inmigrantes extranjeros como un reto atractivo y deseable que puede enriquecerles profesional y humanamente.

Ethnic Identity in an Intercultural Geography: an Empirical Study = L’identité ethnique dans une géographie interculturelle: une étude empirique

This study explored the ethnic identity among 331 emerging adults (144 mestizos and 187 indigenous) from the Intercultural University of Chiapas (México). Scholars suggest that ethnicity is much more salient for ethnic minority adolescents than for adolescents who are members of the ethnic majority. Our aim was to compare the results of the Multigroup Ethnic Identity Measure (MEIM) between the majority ethnic group and the minority group studied. Specifically, the following hypothesis was examined: adolescents who are members of the ethnic minority group (indigenous) will score significantly higher on ethnic identity than adolescents who are members of the ethnic majority group (mestizos). The results supported these hypothesis. We suggest that the effect of an intercultural educative model could explain these results

Desafíos de la cooperación Sur-Sur: China a la cabeza de los “donantes emergentes” (Tema Central)

La cooperación Sur-Sur (CSS) emerge y se consolida ante los constantes cuestionamientos en torno a la cooperación tradicional Norte-Sur. China, a la cabeza de los donantes emergentes “del Sur”, surge como un actor prometedor. Su fuerte dinamismo está cambiando las reglas de juego del sistema internacional de cooperación. Sin embargo, mucho se cuestiona su ayuda como reproductora de las falencias de la cooperación tradicional. Así, China ejemplifica las contradicciones en las que ha caído la CSS: por un lado, las oportunidades de reconfiguración del sistema internacional, y por otro, los desafíos que deberá superar para convertirse en un verdadero modelo alternativo de cooperación y desarrollo en el mundo.

Evidence of heavy metal movement down the profile of a heavily-sludged soil

Two sites in central England where sewage sludge has been deposited for decades were studied to measure the heavy metal distribution in the soil profiles. The first site (S 1) was a field receiving heavy loads sludge from a nearby wastewater treatment plant, and the second (S2) was a farm applying 'normal' sludge rates of 8 t ha(-1) y(-1) of the same sludge. Soil samples were also taken by a near-by untreated control site. In S I the movement of heavy metals was significant even down to 80 cm depth compared to the control. In S2, the concentrations of lead (Pb) and zinc (Zn) and the organic matter content were higher than the control down to 20 cm, while nickel (Ni) moved significantly down to 80 cm. This underlies. the possibility that the metals bound onto organic surfaces moved along with organic matter down to that depth. The movement of metals in S2 points out the potential risks of applying sewage sludge for a long time.

Effect of mycorrhizae and pH change at the root-soil interface on phosphorus uptake by Sorghum using a rhizocylinder technique

Sorghum (Sorghum bicolor) was grown for 40 days in. rhizocylinder (a growth container which permitted access to rh zosphere and nonrhizosphere soil), in two soils of low P status. Soils were fertilized with different rates of ammonium and nitrate and supplemented with 40 mg phosphorus (P) kg(-1) and inoculated with either Glomus mosseae (Nicol. and Gerd.) or nonmycorrhizal root inoculum.. N-serve (2 mg kg(-1)) was added to prevent nitrification. At harvest, soil from around the roots was collected at distances of 0-5, 5-10, and 10-20 mm from the root core which was 35 mm diameter. Sorghum plants, with and without mycorrhiza, grew larger with NH4+ than with NO3- application. After measuring soil pH, 4 3 suspensions of the same sample were titrated against 0.01 M HCl or 0.01 M NaOH until soil pH reached the nonplanted pH level. The acid or base requirement for each sample was calculated as mmol H+ or OFF kg(-1) soil. The magnitude of liberated acid or base depended on the form and rate of nitrogen and soil type. When the plant root was either uninfected or infected with mycorrhiza., soil pH changes extended up to 5 mm from the root core surface. In both soils, ammonium as an N source resulted in lower soil pH than nitrate. Mycorrhizal (VAM) inoculation did not enhance this difference. In mycorrhizal inoculated soil, P depletion extended tip to 20 mm from the root surface. In non-VAM inoculated soil P depletion extended up to 10 mm from the root surface and remained unchanged at greater distances. In the mycorrhizal inoculated soils, the contribution of the 0-5 mm soil zone to P uptake was greater than the core soil, which reflects the hyphal contribution to P supply. Nitrogen (N) applications that caused acidification increased P uptake because of increased demand; there is no direct evidence that the increased uptake was due to acidity increasing the solubility of P although this may have been a minor effect.

Teachers’ voices about being a teacher: comparative studies in England, Finland and Sweden

The aim of the article is to present and discuss a study in which Finnish, English and Swedish teachers and student teachers described the implications of being a teacher. It is cross-national and consists of multiple case studies. Data were collected through twenty-four focus group dialogues, and 110 teachers/student teachers participated in the study. According to the study, we have found that teachers and student teachers in all three countries promoted pupils’ development of critical thinking, which is another way of saying that they focused on ‘the attitudes and values’ aspect of citizenship education; however, this was most evident in the Finnish and the Swedish focus groups. In England there is a subject emphasis to the professional role, the three countries ranked the topics (the pupils; the subject; the organization; the society; teacher identity; parents) equally, in Finland the teacher role did not appear to be as post modern as in the two other countries.

Community strategies in England: reshaping spaces of governance?

The preparation of Community Strategies (CS) has been required of LSPs and Local Authorities in England since the passing of the Local Government Act 2000. This paper examines the process and content of two Community Strategies in southern England as part of an ongoing project to understand their impact and explore ways that CSs may be carried through in a meaningful and effective manner. The paper concludes that the two CSs studied illustrate the challenge faced by LSPs in producing Strategies that are meaningful, inclusive and which follow the spirit of the government CS guidance. LAs and LSPs are also posed with a difficult challenge of seeing through an implicitly required transition from a traditional representative democratic structure/process with a more fluid participatory model. Thus we detect that at least two forms of conflict may arise – firstly with elected councillors threatened by a loss of power and secondly between communities and the LAs who are encouraged to problematise local policy and service delivery in the context of limited resource availability.

Producing leisure spaces out of thin air: the case of the Countryside Stewardship Scheme

This paper examines the growing dysfunction between the apparently increasing significance of diverse leisure practices in the countryside and the largely unchanging official response towards them. Although there is recognition in the recent rural White Paper (DOE and MAFF, 1995) that access is essential to enjoying the countryside, the construction of this term is dubious, since paid access agreements, based on producer requirements, are favoured over any form of demand-driven freedom to roam. Using the Countryside Stewardship Scheme (CSS) as an example of the incentive structure developed to promote this policy, the paper applies Plato's simulacrum as a reading of how this process is being utilised to underpin the dominant rights associated with rural property interests. In particular, the paper makes the point that rather than representing the corollary of a market situation, as its supporters claim, the CSS involves government grant for the eclectic provision of short term licences over ground which remains unmapped as anything other than its continued agricultural use. In concluding, the paper asserts that rather than representing an increase in the availability of leisure sites in the countryside, the CSS and other schemes represent a diversion from the wider and deeper socio-cultural process of continued wealth and power redistribution.

Newbs vs. geeks : encouraging creativity in an online learning community

This article explores the development and creative practices of an online  community within an Australian university. The authors argue that creativity can be enhanced and supported by the development and implementation of purpose-specific learning environments, such as an online learning community. Within such a community the participants are exposed to a number of requisite elements designed to support the exploration of their own learning process and the development of creativity. The following study discusses the establishment of such a community and the social, cultural and learning practices of the student participants.

Exploring creativity support systems for the Ne"X"t generation

This paper explores the implementation of a creativity support system (CSS) for tertiary students studying Games Design and Development at Deakin University, Victoria, Australia. The students at the centre of this study are the ‘next’ generation of learners and are often called the Internet generation because of their pre-imposed for ‘online’ and being ‘connected’. The CSS for the games students is designed within a context that encompasses a ‘whole’ system, as focusing on only one component to augment a person’s creativity does not take into consideration the multitude of factors, for example social factors, that are pertinent on a person ability to grow their creative behaviours. This study will present a set of factors that each CSS should employ to facilitate creative abilities within people, with particular focus on how social activities help to enhance creativity.

Novel spectral descriptor for object shape

In this paper, we propose a novel descriptor for shapes. The proposed descriptor is obtained from 3D spherical harmonics. The inadequacy of 2D spherical harmonics is addressed and the method to obtain 3D spherical harmonics is described. 3D spherical harmonics requires construction of a 3D model which implicitly represents rich features of objects. Spherical harmonics are used to obtain descriptors from the 3D models. The performance of the proposed method is compared against the CSS approach which is the MPEG-7 descriptor for shape contour. MPEG-7 dataset of shape contours, namely, CE-1 is used to perform the experiments. It is shown that the proposed method is effective.

Comparing methods for prescribing exercise for individuals with chronic heart failure

This study examined the accuracy of current recommended guidelines for prescribing exercise intensity using the methods of percentage of heart rate reserve (%HRR), percentage of VO₂ peak (%VO₂peak) and percentage of VO₂ reserve (%VO₂R) in a clinical population of chronic heart failure (CHF) patients. The precision of prescription of exercise intensity for 45 patients with stable CHF (39:6 M:F, 65±9 yrs (mean±SD)) was investigated. VO₂peak testing is relatively common among patients with cardiac disease, but the assessment of VO₂rest is not common practice and the accepted standard value of 3.5 mL/kg/min is assumed in the application of %VO2R (%VO₂R_3.5). In this study, VO₂rest was recorded for 3 min prior to the start of a symptom-limited exercise test on a cycle ergometer. Target exercise intensities were calculated using the VO₂ corresponding to 50 or 80 %HRR, VO₂peak and VO₂R. The VO₂ values were then converted into prescribed speeds on a treadmill in km/hr at 1 %grade using ACSM’s metabolic equation for walking. Target intensities and prescribed treadmill speeds were also calculated with the %VO₂R method using the mean VO₂rest value of participants (3.9 mL/kg/min) (%VO₂R_3.9). This was then compared to the exercise intensities and prescribed treadmill speeds using patient’s measured VO₂rest. Error in prescription correlates the difference between %VO₂R_3.5 and %VO₂R_3.9 compared to %VO₂R with measured VO₂rest. Prescription of exercise intensity through the %HRR method is imprecise for patients on medications that blunt the HR response to exercise. %VO₂R method offers a significant improvement in exercise prescription compared to %VO₂peak. However, a disparity of 10 % still exists in the %VO₂R method using the standard 3.5 mL/kg/min for VO₂rest in the %VO₂R equation. The mean measured VO₂rest in the 45 CHF patients was 11 % higher (3.9±0.8 mL/kg/min) than the standard value provided by ACSM. Applying the mean measured VO₂rest value of 3.9 mL/kg/min rather than the standard assumed value of 3.5 mL/kg/min proved to be closer to the prescribed intensity determined by the actual measured resting VO₂. These results suggest that the %HRR method should not be used to prescribe exercise intensity for CHF patients. Instead, VO₂ should be used to prescribe exercise intensity and be expressed as %VO₂R with measured variables (VO₂rest and VO₂peak).

Forearm blood flow in individuals with CHF and age-matched healthy volunteers : a study and historical review

This study examined forearm blood flow (FBF) in individuals with chronic heart failure (CHF) at rest, moderate exercise, and following limb occlusion. FBF was measured by venous occlusion plethysmography in CHF patients (n = 43) and healthy age-matched volunteers (n = 8) at rest and during exercise consisting of intermittent isometric hand squeezing at 15, 30, and 45% of maximum voluntary contraction (MVC). Peak vasodilatory capacity was also determined following the release of an occluding arm cuff. FBF was lower in CHF patients during exercise and during peak reactive hyperemia (PRH) compared to healthy volunteers, but there was no significant difference between groups at rest. Peak vasodilatory capacity was significantly higher in healthy volunteers than the CHF group ((30.6 ± 8.6 ml±100 mL^-1±min^-1 and 18.3 ± 6.9 ml±100 mL^-1±min^-1, respectively). Local blood flow stimulation in response to exercise or limb occlusion is reduced in individuals with CHF, however, there was no difference in resting flows between the two groups, suggesting vasodilatory medication may restore resting blood flow to healthy values.
