Out of Sync? Demographic and other social science research on health conditions in developing countries  [cached]
Jere Behrman,Julia Behrman,Nykia M. Perez
Demographic Research , 2011,
Abstract: In this paper, we present a framework for considering whether the marginal social benefits of demographic and social science research on various health conditions in developing countries are likely to be relatively high. Based on this framework, we argue that the relative current and future predicted prevalence of burdens of different health/disease conditions, as measured by disability-adjusted life years (DALYs), provide a fairly accurate reflection of some important factors related to the relative marginal social benefits of demographic and social science research on different health conditions. World Health Organization (WHO) DALYs projections for 2005-30 are compared with (a) demographic and other social science studies on health in developing countries during 1990-2005, and (b) presentations made at the Population Association of America annual meetings during the same time period. These comparisons suggest that recent demographic and social science research on health in developing countries has focused too much on HIV/AIDS, and too little on non-communicable diseases.
Developing Reading Automaticity and Fluency: Revisiting What Reading Teachers Know, Putting Confirmed Research into Current Practice  [PDF]
Gail M. Wolf
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96062
Abstract: This article revisits research on reading automaticity and fluency with the goal of helping beginning reading teachers put confirmed research findings into current classroom practice. The article examines the concepts of automaticity and fluency, how both impact the development of skillful reading. The article reviews research on: a) reading strategies children use, and b) repeat reading teaching strategies to develop fluency. Case scenarios illustrate key findings. Based on the research and case scenarios, four conclusions are drawn: 1) The terms automaticity and fluency are often interchanged; the concepts are not the same; 2) Understanding the differences between automaticity and fluency can impact repeat reading teaching strategies; 3) There is an assumption that rapid word recognition is the same cognitive process as automatic word decoding; and 4) There are two pathways to fluent reading, rapid word recognition, and automatic decoding ability. The article presents a theoretical model which aligns with childhood learning theories, offering teachers a variation in repeat reading teaching strategies. Rather than repeating reading the same text, opportunities to read slightly different, decodable text improves decoding, builds fluency, and thus strengthens children’s reading comprehension of complex text.

Abstract: Wave process analysis is one of the newly introduced methods for studying sedimentary basins. It is theoretically based on the wave theory of geophysics which regards the crust motion in the way of wave process. The basic concepts, developments, principles and methods of the wave process analysis in sedimentary basins are presented in this paper. We introduce the four main aspects of current research status of the wave process analysis in detail and discuss its developing trends.

Fruit Growing Research , 2012,
Abstract: Fire blight (Erwinia amylovora) is a very important disease that need to be carefully managed as it is classified as a ’’quarantine disease’’ and can spread itself very quickly when the conditions are favorable (presence of focus, high air humidity and high temperatures, presence of susceptible organs like flowers or long young twigs,..). The study was carried out at Research Institute forFruit Growing Pitesti, Genetic and Breeding Department, during 3 consecutive years (2010-2012), including 36 apple cultivars, old and newly bred. In this study, we present the response of the apple cultivars to fire blight attack, assessed in natural conditions of infection, range a large scale of variability, which denotes a strong influence of the genotype in expression of resistance or susceptibility to disease
RESPONSE OF SEVERAL APPLE VARIETIES TO APPLE SCAB (VENTURIA INAEQUALIS) ATTACK IN CENTRAL TRANSYLVANIA CONDITIONS  [PDF]

Journal of Central European Agriculture , 2004,
Abstract: Among 75 varieties of apple, verified at the Fruit Research Station in Cluj-Napoca, Central Transylvania, Romania, during seven years (between 1990-1996), 38 registered with certain attack degree with apple scab on leaves and fruits. Susceptible on apple scab – Venturia inaequalis (Cke.) Wint. – were the varieties with Japanese origin (i.e. Fuji Aki-fu, Nebuta, Sekai ichi), and in certain years even well known cultivars, as Kaltherer B hmer, Starkrimson, Red Delicious, Mutzu, Wellspur, Jersey Mac which were strongly infected, especially on leaves. Out of all varieties, 31 of them, representing 41.3% were registered with “No attack”, both on leaves and fruits, including genetically resistant varieties Prima, Priscilla, Sir Prize, Liberty, Florina, Priam, Pionier, Voinea, Generos.
Fundamental Research and Developing Countries  [PDF]

Physics , 2002,
Abstract: In the first part of this report, I discuss the sociological role of fundamental research in Developing Countries (DC) and how to realize this program. In the second part, I give a brief and elementary introduction to the field of high-energy physics (HEP), accessible to a large audience not necessary physicists. The aim of this report is to make politicians and financial backers aware on the long-term usefulness of fundamental research in DC and on the possible globalisation of HEP and, in general, of science.

Notulae Botanicae Horti Agrobotanici Cluj-Napoca , 2006,
Abstract: The study presents a comparison of the loss that the fruit suffer during the storage period in both traditional and refrigerating storage, at the Fruit Research Station Cluj-Napoca, Romania. There were gathered biochemical data for four winter maturation apple varieties: Jonathan, Golden Delicious, Starkrimson and Wagener Premiat, during the months of October (at storage), December and March. The determined biochemical aspects were water, total sugar, and ascorbic acid. The refrigerating storage was better in comparison with the traditional storage, confirmed by biochemical composition. The lowest dehydration was for the apples stored in the refrigerating room. By storage method and apples varieties comparison, the lowest water loss was shown by Wagener Premiat varieties and the highest by Jonathan in refrigerating storage in comparison with traditional storage. Wagener Premiat varieties showed the best qualities even for total sugar and ascorbic acid in comparison with the others apples varieties studied. To keep the apples in optimum conditions, the genetic characters of each cultivar and the cultivar behaviour to CA storage is required.
