This paper presents the results of a pilot study examining the factors that impact most on the effective implementation of, and improvement to, Quality Mangement Sytems (QMSs) amongst Indonesian construction companies. Nine critical factors were identified from an extensive literature review, and a survey was conducted of 23 respondents from three specific groups (Quality Managers, Project Managers, and Site Engineers) undertaking work in the Indonesian infrastructure construction sector. The data has been analyzed initially using simple descriptive techniques. This study reveals that different groups within the sector have different opinions of the factors regardless of the degree of importance of each factor. However, the evaluation of construction project success and the incentive schemes for high performance staff, are the two factors that were considered very important by most of the respondents in all three groups. In terms of their assessment of tools for measuring contractor’s performance, additional QMS guidelines, techniques related to QMS practice provided by the Government, and benchmarking, a clear majority in each group regarded their usefulness as ‘of some importance’.

Hereditary nonpolyposis colorectal cancer (HNPCC) is an inherited cancer predisposition syn-drome characterized by early onset colorectal cancer (CRC) and several other extra-colonic cancers, most commonly endometrial cancer (EC) and gastric cancer. Our aim was to evaluate the efficiency and results of the ongoing CRC and EC surveillance programs and to investigate the grounds for future gastric cancer screening by comparing the gastric biopsies of mutation positive and negative siblings in search for premalignant lesions. We also compared a new surveillance method, computerized tomographic colonoscopy (CTC) with optic colonoscopy. The patient material consisted of 579 family members from 111 Finnish HNPCC families al-most all harboring a known mismatch repair gene mutation. The efficacy of CRC and EC surveillance programs on HNPCC patients was evaluated by comparing the stage and survival of cancer cases detected with surveillance versus without. The performance of a new technique, CTC, was explored using a same-day colonoscopy as a reference standard. The use of intrauterine aspiration biopsies for EC surveillance was intro-duced for the first time in a HNPCC setting. Upper GI endoscopies were performed and biop-sies taken from mutation carriers and their mutation-negative siblings. The present surveillance program for CRC proved to be efficient. The CRC cases detected by surveillance were at a significantly more favorable stage than those in the non-surveilled group. This advantage was reflected in a significantly higher CRC-specific survival in the sur-veilled group. The performance of a new technique, CTC was found insufficient for polyp detection in this population in which every polyp, no matter the size, should be detected and removed. Colono-scopy was confirmed as a better surveillance modality than CTC. We could not observe any of the assumed differences in the gastric mucosa from mutation carriers and their mutation-negative siblings and no cases of gastric cancer were detected. The results gave no support for gastric surveillance. The EC surveillance program (transvaginal ultrasound and intra-uterine biopsy every 2-3 years) seemed to be efficient. It yielded several asymptomatic cancer cases and premalignant lesions. The stage distribution of the endometrial cancers in the group under surveillance tended to be more favorable than that of the mutation-positive, symptomatic EC patients who had no surveillance. None of the surveilled EC patients died of EC compared to six in the non-surveilled patients during the follow up. The improvement was, however, not statistically sig-nificant, thus far. Another observation was the good performance of endometrial aspiration biopsies used in this setting for the first time.

In daily life, rich experiences evolve in every environmental and social interaction. Because experience has a strong impact on how people behave, scholars in different fields are interested in understanding what constitutes an experience. Yet even if interest in conscious experience is on the increase, there is no consensus on how such experience should be studied. Whatever approach is taken, the subjective and psychologically multidimensional nature of experience should be respected. This study endeavours to understand and evaluate conscious experiences. First I intro-duce a theoretical approach to psychologically-based and content-oriented experience. In the experiential cycle presented here, classical psychology and orienting-environmental content are connected. This generic approach is applicable to any human-environment interaction. Here I apply the approach to entertainment virtual environments (VEs) such as digital games and develop a framework with the potential for studying experiences in VEs. The development of the methodological framework included subjective and objective data from experiences in the Cave Automatic Virtual Environment (CAVE) and with numerous digital games (N=2,414). The final framework consisted of fifteen factor-analytically formed subcomponents of the sense of presence, involvement and flow. Together, these show the multidimensional experiential profile of VEs. The results present general experiential laws of VEs and show that the interface of a VE is related to (physical) presence, which psychologically means attention, perception and the cognitively evaluated realness and spatiality of the VE. The narrative of the VE elicits (social) presence and involvement and affects emotional outcomes. Psychologically, these outcomes are related to social cognition, motivation and emotion. The mechanics of a VE affect the cognitive evaluations and emotional outcomes related to flow. In addition, at the very least, user background, prior experience and use context affect the experiential variation. VEs are part of many peoples lives and many different outcomes are related to them, such as enjoyment, learning and addiction, depending on who is making the evalua-tion. This makes VEs societally important and psychologically fruitful to study. The approach and framework presented here contribute to our understanding of experiences in general and VEs in particular. The research can provide VE developers with a state-of-the art method (www.eveqgp.fi) that can be utilized whenever new product and service concepts are designed, prototyped and tested.

Sacred groves are patches of forests of special spiritual significance to humans, offering also a diverse range of ecological and environmental services. We have attempted here to understand the local hydrological dynamics of a sacred forest, in terms of the benefits the village community derive, in central Western Ghats region of India. A comparative assessment has been made between two small watersheds in terms of their landscape structure (woody species composition) with soil water properties and availability of water in the respective downstream villages. The result shows that, sacred site with more primeval vegetation has close association with soil moisture in comparison to non-sacred site during dry spell of the year. The higher soil moisture ensures year long availability of water in the downstream village of the sacred site which facilitates farming of commercial crops with higher economic returns to the farmers, unlike the farmers in the other village where they face water crisis during the lean season. The study emphasizes the need for conservation endeavour on sacred groves highlighting its potential for water conservation at local and regional levels.

Con el objetivo de evaluar líneas de sorgo por su resistencia a la mosquita, Stenodiplosis sorghicola (Coq.), se introdujo procedente de la Universidad de Texas A & M, en el año 2004 un vivero de 64 líneas de sorgo con resistencia a mosquita. Se seleccionaron las mejores 35 por aspecto de planta para sembrarlas nuevamente en 2005. Además en 2005 se intro dujo otro vivero de 50 líneas. Los tres viveros se sembraron en surcos de 5 m de largo distribuidos en bloques completos al azar con 3 repeticiones en la época de postrera (Agosto – Diciembre) de 2004 en Santa Rosa y 2005 en CNIA, am bas estaciones experimentales del Instituto Nicaragüense de Tecnología Agropecuaria (INTA). El daño de mosquita se evaluó usando la escala visual para daño elaborada por Fre deriksen et al (1981). También las líneas se evaluaron para rendimiento de grano y se tomó datos de días a floración y altura de planta. Los resultados indican que en 2004 Las lí - neas de mayor rendimiento de grano fueron 02CM1137-BK/ LM, 03CM15085-BK, 03CM15038-BK y 03CM15033-BK con 6002, 5194, 5144 y 5066 kg/ha respectivamente y que el daño de mosquita fue muy bajo. En 2005, en la evaluación de 35 líneas seleccionadas en 2004, las de mayor rendimien to fueron 03CM15038-BK, 03CM15033-BK, 03CM15131 y 01LI9278 con 6406, 6396, 6255 y 6215 kg/ha y daño de mosquita de 1.3, 1.0, 1.3 y 1.0 respectivamente. El daño de mosquita fue severo y algunas líneas no produjeron grano. El menor rendimiento se encontró en la línea 01LI9275 con 280 kg/ha y daño de 8.3. En el vivero nuevo introducido en 2005 las líneas de mayor rendimiento fueron 05:03CM15087-BK, 05:04LI4366, 05:00LI1324 y 05LI4042,43 con 7915, 7238, 6625 y 5088 kg/ha respectivamente y daño de mosquita de 1.0 en las primeras tres líneas y 2.0 en la cuarta. En este vi vero, la línea 05:04LI4015,16 no produjo grano y el daño fue de 9.0.
