    Corporate sponsorship of sports, causes, and the arts has become a mainstream communications tool worldwide. The unique marketing opportunities associated with major events also attract nonsponsoring companies seeking to form associations with the event (ambushing). There are strategies available to brands and events which have been ambushed;…

    Ambush marketing is more than thirty years old, and its prevalence continues to grow. Recent cases indicate that brands perpetrating ambushes are becoming more creative, but the literature has failed to keep pace, offering scant analysis of the different forms that ambushing can take and the implications it can have, and little investigation or consideration from the ambusher’s perspective. This study proposes a new definition of ambushing and typology of the three types of ambush marketing s...

    Many marine zooplankters, particularly among copepods, are "ambush feeders" that passively wait for their prey and capture them by fast surprise attacks. This strategy must be very demanding in terms of muscle power and sensing capabilities, but the detailed mechanisms of the attacks are unknown...... of the examined species is close to this size limit and, in contrast to the larger species, uses its largest possible jump velocity for such attacks. The special requirements to ambush feeders with such attacks may explain why this strategy has evolved to perfection only a few times among planktonic suspension...... feeders ( few copepod families and chaetognaths)....

    The main problem in cancer chemotherapy is the cytotoxic side effects of therapeutics on healthy tissues and cells. The targeted drug delivery and nanotechnology are intensively investigated area to find new ways to solve, at least to reduce, these problems. Hereby, we have reported a new method inspired from both conventional military strategies and biorecognition in the body. In this respect, we have produced two fluorescent nano-drug systems with bitargeting and biorecognition properties, recognizing cancer cells and each other. The multiplexed nanostructures were interacted with HL-60 cells to show their efficiency for bitargeting, ambushing, timed, and double-controlled cancer cell apoptosis.

  5. Ambush frequency should increase over time during optimal predator search for prey.

    2011-11-07

    We advance and apply the mathematical theory of search games to model the problem faced by a predator searching for prey. Two search modes are available: ambush and cruising search. Some species can adopt either mode, with their choice at a given time traditionally explained in terms of varying habitat and physiological conditions. We present an additional explanation of the observed predator alternation between these search modes, which is based on the dynamical nature of the search game they are playing: the possibility of ambush decreases the propensity of the prey to frequently change locations and thereby renders it more susceptible to the systematic cruising search portion of the strategy. This heuristic explanation is supported by showing that in a new idealized search game where the predator is allowed to ambush or search at any time, and the prey can change locations at intermittent times, optimal predator play requires an alternation (or mixture) over time of ambush and cruise search. Thus, our game is an extension of the well-studied 'Princess and Monster' search game. Search games are zero sum games, where the pay-off is the capture time and neither the Searcher nor the Hider knows the location of the other. We are able to determine the optimal mixture of the search modes when the predator uses a mixture which is constant over time, and also to determine how the mode mixture changes over time when dynamic strategies are allowed (the ambush probability increases over time). In particular, we establish the 'square root law of search predation': the optimal proportion of active search equals the square root of the fraction of the region that has not yet been explored.

    Knowledge of genetic structure, geographic distance and environmental heterogeneity can be used to identify environmental features and natural history traits that influence dispersal and gene flow. Foraging mode is a trait that might predict dispersal capacity in snakes, because actively foragers typically have greater movement rates than ambush predators. Here, we test the hypothesis that 2 actively foraging snakes have higher levels of gene flow than 2 ambush predators. We evaluated these 4 co-distributed species of snakes in the Brazilian Amazon. Snakes were sampled along an 880 km transect from the central to the southwest of the Amazon basin, which covered a mosaic of vegetation types and seasonal differences in climate. We analyzed thousands of single nucleotide polymorphisms to compare patterns of neutral gene flow based on isolation by geographic distance (IBD) and environmental resistance (IBR). We show that IBD and IBR were only evident in ambush predators, implying lower levels of dispersal than the active foragers. Therefore, gene flow was high enough in the active foragers analyzed here to prevent any build-up of spatial genotypic structure with respect to geographic distance and environmental heterogeneity. © The American Genetic Association 2017.

    To efficiently locate and assess foods, animal sensory capacities and behavioral discriminations based on them must be appropriate for the diet and method of hunting. In lizards, actively foraging insectivores identify animal prey using lingually sampled chemical cues, but ambush foragers do not.

    Predators influence prey populations not only through predation itself, but also indirectly through prompting changes in prey behaviour. The behavioural adjustments of prey to predation risk may carry nutritional costs, but this has seldom been studied in the wild in large mammals. Here, we studied the effects of an ambush predator, the African lion (Panthera leo), on the diet quality of plains zebras (Equus quagga) in Hwange National Park, Zimbabwe. We combined information on movements of both prey and predators, using GPS data, and measurements of faecal crude protein, an index of diet quality in the prey. Zebras which had been in close proximity to lions had a lower quality diet, showing that adjustments in behaviour when lions are within short distance carry nutritional costs. The ultimate fitness cost will depend on the frequency of predator-prey encounters and on whether bottom-up or top-down forces are more important in the prey population. Our finding is the first attempt to our knowledge to assess nutritionally mediated risk effects in a large mammalian prey species under the threat of an ambush predator, and brings support to the hypothesis that the behavioural effects of predation induce important risk effects on prey populations.

    Sit-and-wait ambushing and active hunting are two strategies used by predators to capture prey. In snakes, hunting strategy is conserved phylogenetically; most species employ only one strategy. Active hunters encounter and capture more prey but invest more energy in hunting and have higher risks of being predated. This trade-off is important to small predators. The small Cerastes vipera employs both modes of hunting, which is unlike most viperids which use only sit-and wait ambushing. This species hibernates in October and emerges in April. Energy intake should be high prior to hibernation to overcome the non-feeding hibernation period and for reproduction on their emergence. We predicted that more individuals would hunt actively towards hibernation and an abiotic factor would trigger this response. Furthermore, since more energy is required for active hunting, we predicted that snakes in good body condition would use active hunting to a greater extent than snakes in poor body condition. To test our predictions, we tracked free-living snakes year round and determined their hunting strategy, estimated their body condition index (BCI), and calculated circannual parameters of day length as environmental cues known to affect animal behaviour. Two novel findings emerged in this study, namely, hunting strategy was affected significantly by 1) the circannual change in day length and 2) by BCI. The proportion of active hunters increased from 5% in April to over 30% in October and BCI of active foragers was higher than that of sit-and-wait foragers and, therefore, our predictions were supported. The entrainment between the proportion of active hunting and the abiotic factor is indicative of an adaptive function for choosing a hunting strategy. A trend was evident among life stages. When all life stages were present (September-October), the proportion of active foragers increased with age: 0.0% among neonates, 18.2% among juveniles and 31.4% among adults. We concluded that

  17. Perceptual advertisement by the prey of stalking or ambushing predators.

    Broom, Mark; Ruxton, Graeme D

    2012-12-21

    There has been previous theoretical explorations of the stability of signals by prey that they have detected a stalking or ambush predator, where such perceptual advertisement dissuades the predator from attacking. Here we use a game theoretical model to extend the theory to consider some empirically-motivated complexities: (i) many perceptual advertisement signals appear to have the potential to vary in intensity, (ii) higher intensity signals are likely to be most costly to produce, and (iii) some high-cost signals (such as staring directly at the predator) can only be utilised if the prey is very confident of the existence of a nearby predator (that is, there are reserved or unfakable signals). We demonstrate that these complexities still allow for stable signalling. However, we do not find solutions where prey use a range of signal intensities to signal different degrees of confidence in the proximity of a predator; with prey simply adopting a binary response of not signalling or always signalling at the same fixed level. However this fixed level will not always be the cheapest possible signal, and we predict that prey that require more certainty about proximity of a predator will use higher-cost signals. The availability of reserved signals does not prohibit the stability of signalling based on lower-cost signals, but we also find circumstances where only the reserved signal is used. We discuss the potential to empirically test our model predictions, and to develop theory further to allow perceptual advertisement to be combined with other signalling functions.

    In order to gain insight into the various parts of the transportation physical protection system, a tactical board game, AMBUSH, was developed. The paper discusses the purpose and features of AMBUSH. AMBUSH can be used to help provide insight into the value of additional vehicles, guards, cargo barriers, equipment and alternative tactics. One value of using AMBUSH comes from the player participation in the events that take place. The tasks that are executed at any game turn are based on a human interpretation of the current overall situation and on which strategies appear to optimize the chance of success. Thus, this game may also be valuable as a training device for the transportation guard force. An advantage over computer-based combat simulation models is that AMBUSH is easily transportable and relatively inexpensive

  19. THE AMBUSH OF AFRICAN PHILOSOPHY: AN EXHUMATION OF CLASSICAL LIBERAL PRINCIPLES IN THE EVOLUTION OF AFRICA SOCIETIES

    Directory of Open Access Journals (Sweden)

    Ibrahim B. Anoba

    2017-05-01

    Full Text Available The persistent resentment towards classical liberal principles especially individualism and free market in contemporary Africa, represents an outcome of decades of ambush against the ideology despite its clear connections with traditional African philosophy and relevance to the prosperity of modern African states. This work attempts to draw comparisons between social and economic organisation in traditional Africa and classical liberal principles. Contrary to literatures that portray the community as the real and only end in traditional African societies, elements like free trade; market economy; consensus; anarchy and limited governance negates this position. While tracing the cause of Africa’s cling to socialism and communism, this paper presents an ideological transition from pre-colonialism to nationalist and post-independent Africa. It concludes by demystifying the arguments of individualism as antithetical to African morality. It also justified the inevitability of classical liberal principles in modern Africa.

    Full Text Available At present the biological control as a pest control technology is becoming more desirable. Biological formulations on basis of entomopathogenic nematodes are one of the effective means for the protection of agricultural and forest plants from harmful insects. Nowadays, the use of entomopathogenic nematodes as biological control agents is a key component in IPM system. The foraging strategies of entomopathogenic nematodes (EPNs vary between species. This variation is consistent with use of different foraging strategies between ambush, cruise and intermediate to find their host insects. In order to ambush prey, some species of EPNs nictate, or raise their bodies of the soil surface so they are better poised to attach passing insects, other species adopt a cruising strategy and rarely nictate. Some species adopt an intermediate strategy between ambush and cruise. We compared in laboratory the foraging strategies of the entomopathogenic nematode species: Steinernema carpocapsae, Heterorhabditis bacteriophora and the recently described species Steinernema tbilisiensis and assessed their virulence against mealworm beetle, Tenebrio molitor L. (Coleoptera: Tenebrionidae. The tests showed that S. tbilisiensis adopts both foraging strategies.

    Full Text Available The community development and empowerment are two inseparable sides in the efforts to overcome the phenomenon of the fishermen communities, especially in the efforts to increase the welfare through the increasing income in the fishermen communities. One of the media in implementing the community development and empowerment is through the fishermen groups. The role of fishermen groups has not run optimally yet in improving the fishermen’s welfare, so it requires a strategy of developing the fishermen groups through the strategy of strengthening the economy in order to increase the fishermen’s income. This research aims to determine the priority of aspects to determine the strategies and to analyze the priority of strategy of strengthening the economy through the development of the institutional fishermen groups in order to increase the fishermen income in Central Java. The method of analysis in this research uses the Analytic Hierarchy Process (AHP. The result of AHP analysis indicates the priority of aspects in the strategy of strengthening the economy those are: aspects of participation,aspects of capital, aspects of partnership, and aspects of technology. The priority of alternatives in the strategy of strengthening the fishermen’s economy shows three sequences of 12 alternatives of strategies those are:  the  socialization of the importance of groups, the increase in the active participation, and the increase in the number of meetings.

    Vu, Hai Canh; Do, Phuc; Barros, Anne; Bérenguer, Christophe

    2014-01-01

    This paper presents a dynamic maintenance grouping strategy for multi-component systems with both “positive” and “negative” economic dependencies. Positive dependencies are commonly due to setup cost whereas negative dependencies are related to shutdown cost. Actually, grouping maintenance activities can save part of the setup cost, but can also in the same time increase the shutdown cost. Until now, both types of dependencies have been jointly taken into account only for simple system structures as pure series. The first aim of this paper is to investigate the case of systems with any combination of basic structures (series, parallel or k-out-of n structures). A cost model and a heuristic optimization scheme are proposed since the optimization of maintenance grouping strategy for such multi-component systems leads to a NP-complete problem. Then the second objective is to propose a finite horizon (dynamic) model in order to optimize online the maintenance strategy in the presence of dynamic contexts (change of the environment, the working condition, the production process, etc). A numerical example of a 16-component system is finally introduced to illustrate the use and the advantages of the proposed approach in the maintenance optimization framework. - Highlights: • A dynamic grouping maintenance strategy for complex structure systems is proposed. • Impacts of the system structure on grouping maintenance are investigated. • A grouping approach based on the rolling horizon and GA algorithm is proposed. • Different dynamic contexts and their impacts on grouping maintenance are studied. • The proposed approach can help to update the maintenance planning in dynamic contexts

We developed a correlational empirical study with a sample composed of 73 work groups, taken from 14 organizations in the industrial and service sectors. The results showed that groups in task conflict situations choose integrative strategies more often than when in relational conflict situations. Moreover, avoiding strategies were more likely to be used in relational conflict situations than in task conflict situations. On the other hand, our results showed that the frequency with which a group uses an integrative strategy can be considered a significant (positive predictor of group satisfaction for both types of conflict situations (task and relationship. Our results are discussed and compared with our previous literature review, as well as the implications and limitations of the study, along with some thoughts on further investigation.

  11. The impact of instructor grouping strategies on student efficacy in inquiry science labs: A phenomenological case study of grouping perceptions and strategies

    Science.gov (United States)

    Miller, Nathaniel J.

    Abundant educational research has integrated Albert Bandura's concepts of self-efficacy and collective efficacy within educational settings. In this phenomenological case study, the investigation sought to capture the manifestation of self-efficacy and collective efficacy within inquiry-based science laboratory courses. Qualitative data was derived from student efficacy surveys, direct classroom observations, and three-tiered interviews with teacher participants. Four high school science instructors and their students from two school districts in Northern Illinois were selected to participate in the study. This study sought to identify instructor strategies or criteria used to formulate student laboratory groups and the impact of such groupings on student self-efficacy and collective efficacy. Open coding of interview transcripts, observation logs, and student surveys led to the development of eight emerging themes. These themes included the purpose of science laboratory activities, instructor grouping strategies, instructor roles, instructor's perceptions, science laboratory assessment, student interactions, learner self-perceptions, and grouping preferences. Results from the study suggest that some students were innately inclined to assume leadership roles, smaller groupings had greater participation from all group members, students had a strong preference for working collaboratively in groups, and students desired to maintain stable laboratory groups in lieu of periodically changing laboratory partners. As with all case study methodologies, the findings of the study were limited to the individual participants at research sites and were not generalizable to all science classrooms. Additional research in the realms of group size, group autonomy, and student interviews would provide even greater insights into the observed phenomena.

  12. Digestive and locomotor capacity show opposing responses to changing food availability in an ambush predatory fish.

    Science.gov (United States)

    Fu, Shi-Jian; Peng, Jing; Killen, Shaun S

    2018-06-14

    Metabolic rates vary widely within species, but little is known about how variation in the 'floor' [i.e. standard metabolic rate (SMR) in ectotherms] and 'ceiling' [maximum metabolic rate (MMR)] for an individual's aerobic scope (AS) are linked with digestive and locomotor function. Any links among metabolic traits and aspects of physiological performance may also be modulated by fluctuations in food availability. This study followed changes in SMR, MMR, and digestive and locomotor capacity in southern catfish ( Silurus meridionalis ) throughout 15 days of food deprivation and 15 days of refeeding. Individuals downregulated SMR during food deprivation and showed only a 10% body mass decrease during this time. Whereas critical swim speed ( U crit ) was robust to food deprivation, digestive function decreased after fasting with a reduced peak oxygen uptake during specific dynamic action (SDA) and prolonged SDA duration. During refeeding, individuals displayed rapid growth and digestive function recovered to pre-fasting levels. However, refed fish showed a lower U crit than would be expected for their increased body length and in comparison to measures at the start of the study. Reduced swimming ability may be a consequence of compensatory growth: growth rate was negatively correlated with changes in U crit during refeeding. Southern catfish downregulate digestive function to reduce energy expenditure during food deprivation, but regain digestive capacity during refeeding, potentially at the cost of decreased swimming performance. The plasticity of maintenance requirements suggests that SMR is a key fitness trait for in this ambush predator. Shifts in trait correlations with food availability suggest that the potential for correlated selection may depend on context. © 2018. Published by The Company of Biologists Ltd.

    The application of elaborative encoding strategies during learning, such as grouping items on similar semantic categories, increases the likelihood of later recall. Previous studies have suggested that stimuli that encourage semantic grouping strategies had modulating effects on specific ERP components. However, these studies did not differentiate between ERP activation patterns evoked by elaborative working memory strategies like semantic grouping and more simple strategies like rote rehearsal. Identification of neurocognitive correlates underlying successful use of elaborative strategies is important to understand better why certain populations, like children or elderly people, have problems applying such strategies. To compare ERP activation during the application of elaborative versus more simple strategies subjects had to encode either four semantically related or unrelated pictures by respectively applying a semantic category grouping or a simple rehearsal strategy. Another goal was to investigate if maintenance of semantically grouped vs. ungrouped pictures modulated ERP-slow waves differently. At the behavioral level there was only a semantic grouping benefit in terms of faster responding on correct rejections (i.e. when the memory probe stimulus was not part of the memory set). At the neural level, during encoding semantic grouping only had a modest specific modulatory effect on a fronto-central Late Positive Component (LPC), emerging around 650 ms. Other ERP components (i.e. P200, N400 and a second Late Positive Component) that had been earlier related to semantic grouping encoding processes now showed stronger modulation by rehearsal than by semantic grouping. During maintenance semantic grouping had specific modulatory effects on left and right frontal slow wave activity. These results stress the importance of careful control of strategy use when investigating the neural correlates of elaborative encoding. Copyright © 2014 Elsevier B.V. All rights

  14. Heat, sight and scent: multiple cues influence foraging site selection by an ambush-foraging snake Hoplocephalus bungaroides (Elapidae

    2009-08-01

    Full Text Available Most mobile organisms respond to multiple cues when selecting habitat types, and laboratory experiments that manipulate only single cues may fail to reveal the true complexity of habitat-selection behaviour. In south-eastern Australia, broad-headed snakes Hoplocephalus bungaroides (Elapidae lie in wait under sun-warmed rocks to ambush velvet geckos Oedura leseuerii (Gekkonidae. Previous laboratory work has shown that both the geckos and the snakes actively select hotter rather than colder rocks, and that the snakes actively select rocks scented by geckos. We manipulated rock temperature and the presence of two types of cues from geckos (chemical and visual information to clarify the causal basis for foraging site selection by the juveniles of this snake. When given a choice between cold lizard-scented rocks and hot unscented rocks, our captive snakes gave a higher priority to lizard scent than to temperature. The snakes also selected shelter-sites that provided visual as well as scent cues from lizards, rather than shelter-sites with scent cues alone. Thus, although broad-headed snakes show a direct preference for hotter rather than colder rocks in the laboratory, their choice of foraging site in the field may also be influenced by the presence of scent cues from prey. Our laboratory results suggest that habitat selection by broad-headed snakes may be more complex than has been suggested by previous single-factor laboratory trials[Current Zoology 55(4: 266–271, 2009].

    2014-01-01

    Full Text Available Agent based simulation method has become a prominent approach in computational modeling and analysis of public emergency management in social science research. The group emotions evolution, information diffusion, and collective behavior selection make extreme incidents studies a complex system problem, which requires new methods for incidents management and strategy evaluation. This paper studies the group emotion evolution and intervention strategy effectiveness using agent based simulation method. By employing a computational experimentation methodology, we construct the group emotion evolution as a complex system and test the effects of three strategies. In addition, the events-chain model is proposed to model the accumulation influence of the temporal successive events. Each strategy is examined through three simulation experiments, including two make-up scenarios and a real case study. We show how various strategies could impact the group emotion evolution in terms of the complex emergence and emotion accumulation influence in extreme events. This paper also provides an effective method of how to use agent-based simulation for the study of complex collective behavior evolution problem in extreme incidents, emergency, and security study domains.

    2012-01-01

    In this paper, quantum strategies are introduced within evolutionary games in order to investigate the evolution of quantum and classical strategies on networks in the public goods game. Comparing the results of evolution on a scale-free network and a square lattice, we find that a quantum strategy outperforms the classical strategies, regardless of the network. Moreover, a quantum strategy dominates the population earlier in group interactions than it does in pairwise interactions. In particular, if the hub node in a scale-free network is occupied by a cooperator initially, the strategy of cooperation will prevail in the population. However, in other situations, a quantum strategy can defeat the classical ones and finally becomes the dominant strategy in the population. (paper)

    To consider the extent, nature, and range of risk arrangements between physician groups and health maintenance organizations (HMOs) for self-administered injectable (SAI) drugs; to examine types and frequencies of SAI drug-use management strategies adopted by physician groups; and to explore the relationship between locus and level of financial risk for SAIs and physician group strategy adoption. We used a multiple case-study design to select physician groups and their health maintenance organization (HMO) contractual partners in 4 markets in the United States (Northwest, Northeast, Midwest, Southwest). Physician groups in these markets were chosen based on size (e50 physicians) and experience with drug risk (e1 year). Physician groups were asked to identify their 3 major HMO contractual partners in each market. Telephone interviews were conducted from January 2000 to June 2001, with the resulting purposive sample of 37 individuals representing 20 physician groups. We found that the level and locus of SAI financial risk were related to the adoption of management strategies. Physician groups with higher financial risk for SAIs adopted more strategies than lower-risk groups. Groups with SAI financial risk in the medical services capitation (MSC) adopted 9.2 strategies per group. In contrast, groups with SAI financial risk in the pharmacy-risk budget (PRB) averaged 1.5 strategies per group. Groups with SAI financial risk in both the MSC and PRB fell in-between, averaging 4.5 strategies per group. The most frequently adopted strategy was designing evidenced-based therapeutic guidelines, i.e., protocols based on evidence from the peer-reviewed literature used to guide physicians in the treatment of typically chronic conditions (9 groups, 45% of sample). The second most common strategy involved adapting the existing utilization management system to process SAIs (7 groups, 35%) and the establishment of office procedures for internal authorization (5 groups, 25%).

    2015-11-01

    The selection of an ambush-cum-foraging site and proper prey are indispensable for maintaining an adequate energy intake by sit-and-wait predators to optimize survival and future fitness. This is important for snakes, where an ambush site has suitable ambience. We studied the foraging strategy of the Palestine Saw-scaled Viper (Echis coloratus) at an avian migratory stopover site. Following initial observations, we hypothesized that vipers are able to discern the body mass of a perched bird and hunt accordingly. We implemented an experiment where vipers chose between four groups of migratory Blackcaps with different body mass. Prey choice by vipers of both age classes was not random and adults focused on Blackcaps with the lightest body mass. Juveniles displayed a variability of prey choice but selected mainly birds from the lightest categories. We concluded that Saw-scaled Vipers hunt prey based on thermal cues; juveniles practice on different prey groups prior to perfecting their foraging techniques i.e., hunting is a learned process; and that they prefer birds with the lowest body mass. The last because Blackcaps, when on migration, save energy by entering a state of deep torpor in which they sacrifice their vigilance capabilities. Copyright © 2015 Elsevier B.V.

  6. A strategic conflict avoidance approach based on cooperative coevolutionary with the dynamic grouping strategy

    Conflict avoidance plays a crucial role in guaranteeing the safety and efficiency of the air traffic management system. Recently, the strategic conflict avoidance (SCA) problem has attracted more and more attention. Taking into consideration the large-scale flight planning in a global view, SCA can be formulated as a large-scale combinatorial optimisation problem with complex constraints and tight couplings between variables, which is difficult to solve. In this paper, an SCA approach based on the cooperative coevolution algorithm combined with a new decomposition strategy is proposed to prevent the premature convergence and improve the search capability. The flights are divided into several groups using the new grouping strategy, referred to as the dynamic grouping strategy, which takes full advantage of the prior knowledge of the problem to better deal with the tight couplings among flights through maximising the chance of putting flights with conflicts in the same group, compared with existing grouping strategies. Then, a tuned genetic algorithm (GA) is applied to different groups simultaneously to resolve conflicts. Finally, the high-quality solutions are obtained through cooperation between different groups based on cooperative coevolution. Simulation results using real flight data from the China air route network and daily flight plans demonstrate that the proposed algorithm can reduce the number of conflicts and the average delay effectively, outperforming existing approaches including GAs, the memetic algorithm, and the cooperative coevolution algorithms with different well-known grouping strategies.

    2013-10-01

    Full Text Available In recent years, a number of studies have been conducted with regard to communication strategy training and performance on communicative tasks (Lam, 2009; Nakatani, 2010; Naughton, 2006. This study aims to add to the literature by examining how two strategies, clarifying/confirming and extending a conversation, and two methods of teaching the strategies, affected the interactional sequences and overall group discussion performance of EFL students at a university in Japan. Pre and posttreatment small-group discussions were recorded for assessment, and a stimulated recall interview was administered to determine the participants’ perceptions of their learning and language use. Posttest results reveal that the experimental groups that were taught predetermined phrases aimed at clarifying/confirming and extending a conversation employed such phrases more frequently than the control group. However, this employment of phrases did not lead to higher gains in group discussion skills as the control group enjoyed the largest gains from pre to posttest. The researchers consider the findings in light of previous research, and conclude with recommendations for future research on the topic with special regard to research design.

    2014-10-01

    Market forces in health care have created substantial regulatory, legislative, and reimbursement changes that have had a significant impact on urology group practices. To maintain viability, many urology groups have merged into larger integrated entities. Although group operations vary considerably, the majority of groups have struggled with the development of a strong culture, effective decision-making, and consensus-building around shared resources, income, and expense. Creating a sustainable business model requires urology group leaders to allocate appropriate time and resources to address these issues in a proactive manner. This article outlines collaboration strategies for creating an effective culture, governance, and leadership, and provides practical suggestions for optimizing the performance of the urology group practice.

  11. Do seedling functional groups reflect ecological strategies of woody plant species in Caatinga?

    Directory of Open Access Journals (Sweden)

    Tatiane Gomes Calaça Menezes

    2017-11-01

    Full Text Available ABSTRACT It is assumed that morphological traits of seedlings reflect different strategies in response to environmental conditions. The ecological significance of this has been widely documented in rainforests, where habitat structure and species interactions play an important role in community assembly. However, in seasonally dry ecosystems, where environmental filtering is expected to strongly influence community structure, this relationship is poorly understood. We investigated this relationship between functional groups of seedlings and life history traits and tested whether functional group predicts the ecological strategies employed by woody species to deal with the stressful conditions in seasonally dry ecosystems. Seedling functional groups, life history traits and traits that reflect ecological strategies for occupying seasonally dry environments were described for twenty-six plant species. Seedlings of species from the Caatinga vegetation exhibited a functional profile different from that observed in rainforests ecosystems. Phanerocotylar-epigeal seedlings were the most frequently observed groups, and had the largest range of ecological strategies related to dealing with seasonally dry environments, while phanerocotylar-hypogeal-reserve seedlings exhibited an increase in frequency with seasonality. We discuss these results in relation to those observed in other tropical forests and their ecological significance in seasonally dry environments.

  13. The aerodynamic signature of running spiders.

    Directory of Open Access Journals (Sweden)

    Jérôme Casas

    Full Text Available Many predators display two foraging modes, an ambush strategy and a cruising mode. These foraging strategies have been classically studied in energetic, biomechanical and ecological terms, without considering the role of signals produced by predators and perceived by prey. Wolf spiders are a typical example; they hunt in leaf litter either using an ambush strategy or by moving at high speed, taking over unwary prey. Air flow upstream of running spiders is a source of information for escaping prey, such as crickets and cockroaches. However, air displacement by running arthropods has not been previously examined. Here we show, using digital particle image velocimetry, that running spiders are highly conspicuous aerodynamically, due to substantial air displacement detectable up to several centimetres in front of them. This study explains the bimodal distribution of spider's foraging modes in terms of sensory ecology and is consistent with the escape distances and speeds of cricket prey. These findings may be relevant to the large and diverse array of arthropod prey-predator interactions in leaf litter.

    2014-01-01

    In group settings, background noise and an obstructed view of the speaker are just a few of the issues that can make workplace communication difficult for an individual who is deaf or hard of hearing. Accommodation strategies such as amplification of the speaker's voice or the use of text-based alternatives exist to address these issues. However, recent studies have shown that there are still unmet needs related to workplace communication in group settings for individuals who are deaf or hard of hearing. Identify the most common strategies used by individuals who are deaf or hard of hearing to improve communication in group settings and gauge the perceived effectiveness of those strategies. An online survey was conducted with individuals who self-identified as deaf or hard of hearing. The survey presented specific communication strategies based on three functional approaches (aural/oral, text, visual). The strategies applied to both receptive and expressive communication in five different meeting types ranging in size and purpose. 161 adults (age 22-90 yrs.) with limited hearing ability completed the survey. Text-based strategies were typically the least frequently used strategies in group settings, yet they ranked high in perceived effectiveness for receptive and expressive communication. Those who used an interpreter demonstrated a strong preference for having a qualified interpreter present in the meeting rather than an interpreter acting remotely. For expressive communication, participants in general preferred to use their own voice or signing abilities and ranked those strategies as highly effective. A more accessible workplace for individuals who are deaf or hard of hearing would incorporate more ubiquitous text-based strategy options. Also, qualified interpreters, when used, should be present in the meeting for maximum effectiveness.

    Longini, Ira M; Halloran, M Elizabeth

    2005-02-15

    Despite evidence that vaccinating schoolchildren against influenza is effective in limiting community-level transmission, the United States has had a long-standing government strategy of recommending that vaccine be concentrated primarily in high-risk groups and distributed to those people who keep the health system and social infrastructure operating. Because of this year's influenza vaccine shortage, a plan was enacted to distribute the limited vaccine stock to these groups first. This vaccination strategy, based on direct protection of those most at risk, has not been very effective in reducing influenza morbidity and mortality. Although it is too late to make changes this year, the current influenza vaccine crisis affords the opportunity to examine an alternative for future years. The alternative plan, supported by mathematical models and influenza field studies, would be to concentrate vaccine in schoolchildren, the population group most responsible for transmission, while also covering the reachable high-risk groups, who would also receive considerable indirect protection. In conjunction with a plan to ensure an adequate vaccine supply, this alternative influenza vaccination strategy would help control interpandemic influenza and be instrumental in preparing for pandemic influenza. The effectiveness of the alternative plan could be assessed through nationwide community studies.

    Full Text Available Objective: The aim of this study was to examine the effectiveness of group training of procedural emotion regulation strategies in cognitive coping of individuals suffering substance abuse. Method: A quasi-experimental design along with pretest-posttest and control group was used for this study. Then, 16 patients suffering substance abuse were selected through convenience sampling and were randomly assigned to two control and experimental groups. The experimental group received 10 sessions of group training of procedural emotion regulation strategies while the control group received no treatment. Both groups before and after the treatment completed the Persian version of cognitive emotion regulation questionnaire (Hasani, 2011. Results: The results showed that group training of e procedural motion regulation strategies leads to a reduction in maladaptive strategies such as self-blame, rumination, catastrophizing, and other-blame and an increase in adaptive strategies such as refocus on planning, positive reappraisal, and perspective development. Conclusion: Training of procedural emotion regulation strategies via the reduction of maladaptive and increase of adaptive cognitive emotion regulation strategies can provide the opportunity for the improvement and non-return to substance abuse.

    The design and synthesis of multivalent ligands displaying complex oligosaccharides is necessary for the development of therapeutics, diagnostics, and research tools. Here, we report an efficient conjugation strategy to prepare complex glycoconjugates with 4 copies of 1 or 2 separate glycan epitopes, providing 4-8 carbohydrate residues on a tetravalent poly(ethylene glycol) scaffold. This strategy provides complex glycoconjugates that approach the size of glycoproteins (15-18 kDa) while remaining well-defined. The synthetic strategy makes use of three orthogonal functional groups, including a reactive N-hydroxysuccinimide (NHS)-ester moiety on the linker to install the first carbohydrate epitope via reaction with an amine. A masked amine functionality on the linker is revealed after the removal of a fluorenylmethyloxycarbonyl (Fmoc)-protecting group, allowing the attachment to the NHS-activated poly(ethylene glycol) (PEG) scaffold. An azide group in the linker was then used to incorporate the second carbohydrate epitope via catalyzed alkyne-azide cycloaddition. Using a known tetravalent PEG scaffold (PDI, 1.025), we prepared homofunctional glycoconjugates that display four copies of lactose and the A-type II or the B-type II human blood group antigens. Using our trifunctional linker, we expanded this strategy to produce heterofunctional conjugates with four copies of two separate glycan epitopes. These heterofunctional conjugates included Neu5Ac, 3'-sialyllactose, or 6'-sialyllactose as a second antigen. Using an alternative strategy, we generated heterofunctional conjugates with three copies of the glycan epitope and one fluorescent group (on average) using a sequential dual-amine coupling strategy. These conjugation strategies should be easily generalized for conjugation of other complex glycans. We demonstrate that the glycan epitopes of heterofunctional conjugates engage and cluster target B-cell receptors and CD22 receptors on B cells, supporting the

  6. Prey detection and prey capture in copepod nauplii

    DEFF Research Database (Denmark)

    Bruno, Eleonora; Borg, Marc Andersen; Kiørboe, Thomas

    2012-01-01

    Copepod nauplii are either ambush feeders that feed on motile prey or they produce a feeding current that entrains prey cells. It is unclear how ambush and feeding-current feeding nauplii perceive and capture prey. Attack jumps in ambush feeding nauplii should not be feasible at low Reynolds...... (Temora longicornis). We demonstrate that the ambush feeders both detect motile prey remotely. Prey detection elicits an attack jump, but the jump is not directly towards the prey, such as has been described for adult copepods. Rather, the nauplius jumps past the prey and sets up an intermittent feeding...

    2014-01-01

    Full Text Available This paper focuses on the optimization of an internal coordinated procurement logistics system in a steel group and the decision on the coordinated procurement strategy by minimizing the logistics costs. Considering the coordinated procurement strategy and the procurement logistics costs, the aim of the optimization model was to maximize the degree of quality satisfaction and to minimize the procurement logistics costs. The model was transformed into a single-objective model and solved using a simulated annealing algorithm. In the algorithm, the supplier of each subsidiary was selected according to the evaluation result for independent procurement. Finally, the effect of different parameters on the coordinated procurement strategy was analysed. The results showed that the coordinated strategy can clearly save procurement costs; that the strategy appears to be more cooperative when the quality requirement is not stricter; and that the coordinated costs have a strong effect on the coordinated procurement strategy.

    The authors examined the relations between (a) the perceptions of dual identity and separate groups and (b) intergroup conflict management strategies, in two contexts: the conflict between the secular and religious sectors in Israel and the allocation of resources among organizational subunits. In both contexts, contention (i.e., forcing one's will on the other party) was associated with the perception of separate groups. Only in the organizational context, avoidance (i.e., doing nothing or discontinuing participation in the conflict) was associated with the perception of dual identity. Problem solving (i.e., finding a solution that is acceptable to both parties) was related to the perception of dual identity in the secular-religious context. In the organizational context, this relation appeared only under a low perception of separate groups. Yielding (i.e., satisfying the other party's needs at the expense of one's own) was related to the perception of dual identity in the organizational context. In the secular-religious context, this relation appeared only under a high perception of separate groups. The authors discussed the varying pattern of the associations between (a) the perceptions of dual identity and separate groups and (b) the conflict management strategies in the two contexts in terms of the Dual Concern Model and the perceived feasibility of the strategies.

  12. Strategy of competition between two groups based on an inflexible contrarian opinion model.

    2011-12-01

    We introduce an inflexible contrarian opinion (ICO) model in which a fraction p of inflexible contrarians within a group holds a strong opinion opposite to the opinion held by the rest of the group. At the initial stage, stable clusters of two opinions, A and B, exist. Then we introduce inflexible contrarians which hold a strong B opinion into the opinion A group. Through their interactions, the inflexible contrarians are able to decrease the size of the largest A opinion cluster and even destroy it. We see this kind of method in operation, e.g., when companies send free new products to potential customers in order to convince them to adopt their products and influence others to buy them. We study the ICO model, using two different strategies, on both Erdös-Rényi and scale-free networks. In strategy I, the inflexible contrarians are positioned at random. In strategy II, the inflexible contrarians are chosen to be the highest-degree nodes. We find that for both strategies the size of the largest A cluster decreases to 0 as p increases as in a phase transition. At a critical threshold value, p(c), the system undergoes a second-order phase transition that belongs to the same universality class of mean-field percolation. We find that even for an Erdös-Rényi type model, where the degrees of the nodes are not so distinct, strategy II is significantly more effective in reducing the size of the largest A opinion cluster and, at very small values of p, the largest A opinion cluster is destroyed.

    2010-01-01

    Plant-ants live in a mutualistic association with host plants known as “myrmecophytes” that provide them with a nesting place and sometimes with extra-floral nectar (EFN) and/or food bodies (FBs); the ants can also attend sap-sucking Hemiptera for their honeydew. In return, plant-ants, like most other arboreal ants, protect their host plants from defoliators. To satisfy their nitrogen requirements, however, some have optimized their ability to capture prey in the restricted environment represented by the crowns of trees by using elaborate hunting techniques. In this study, we investigated the predatory behavior of the ant Azteca andreae which is associated with the myrmecophyte Cecropia obtusa. We noted that up to 8350 ant workers per tree hide side-by-side beneath the leaf margins of their host plant with their mandibles open, waiting for insects to alight. The latter are immediately seized by their extremities, and then spread-eagled; nestmates are recruited to help stretch, carve up and transport prey. This group ambush hunting technique is particularly effective when the underside of the leaves is downy, as is the case for C. obtusa. In this case, the hook-shaped claws of the A. andreae workers and the velvet-like structure of the underside of the leaves combine to act like natural Velcro® that is reinforced by the group ambush strategy of the workers, allowing them to capture prey of up to 13,350 times the mean weight of a single worker.

    Progress has been made in understanding strategic decision making influencing anesthesia groups' operating room business practices. However, there has been little analysis of the remaining gaps in our knowledge. We performed a needs assessment to identify unsolved problems in anesthesia business strategy based on Porter's Five Forces Analysis. The methodology was a narrative literature review. We found little previous investigation for 2 of the 5 forces (threat of new entrants and bargaining power of suppliers), modest understanding for 1 force (threat of substitute products or services), and substantial understanding for 2 forces (bargaining power of customers and jockeying for position among current competitors). Additional research in strategic decisions influencing anesthesia groups should focus on the threat of new entrants, bargaining power of suppliers, and the threat of substitute products or services.

    2017-02-01

    Full Text Available Roland Bal analyzes the strategies his research group developed to deal with the interlinked dynamics of research evaluation in a multi-disciplinary institutional environment characteristic of much STS research. Scholars in such environments constantly need to navigate and negotiate the standards of evaluation, in complex choreographies of cooperation and competition with other disciplinary groups. Bal describes strategies his group has successfully used, and how these strategies have both shifted the way research quality is assessed within the department as well as changed the way his group works and publishes. In conclusion, he describes performance management systems and research practices as co-constituted and calls for a debate on which forms of evaluation infrastructures allow for better ways of doing research in STS.

    Full Text Available Aim. To explore what strategies the supervisors found beneficial to prevent or reduce sickness absence among employees with musculoskeletal complaints. Methods. Five focus groups were conducted and 26 supervisors from health and social sector participated. Commonly used strategies to prevent sickness absence and interdisciplinary cooperation in this work were discussed in the focus groups. Systematic text condensation was used to analyse the data. Results. The supervisors described five strategies for sick leave management: (1 promoting well-being and a healthy working environment, (2 providing early support and adjustments, (3 making employees more responsible, (4 using confrontational strategies in relation to employees on long-term sick leave, and (5 cooperation with general practitioners (GPs. Conclusions. Strategies of promoting a healthy working environment and facilitating early return to work were utilised in the follow-up of employees with musculoskeletal complaints. Supportive strategies were found most useful especially in the early phases, while finding a balance between being supportive, on one side, and confronting the employee, on the other, was endeavoured in cases of recurrent or long-term sick leave. Further, the supervisors requested a closer cooperation with the GPs, which they believed would facilitate return to work.

  20. Direct fitness of group living mammals varies with breeding strategy, climate and fitness estimates.

    2012-09-01

    1. Understanding how variation in fitness relates to variation in group living remains critical to determine whether this major aspect of social behaviour is currently adaptive. 2. Available evidence in social mammals aimed to examine this issue remains controversial. Studies show positive (i.e. potentially adaptive), neutral or even negative fitness effects of group living. 3. Attempts to explain this variation rely on intrinsic and extrinsic factors to social groups. Thus, relatively more positive fitness effects are predicted in singularly breeding as opposed to plural breeding species. Fitness effects of sociality in turn may depend on ecological conditions (i.e. extrinsic factors) that influence associated benefits and costs. 4. We used meta-analytic tools to review how breeding strategy or ecological conditions influence the effect size associated with direct fitness-sociality relationships reported in the mammalian literature. Additionally, we determined how taxonomic affiliation of species studied, different fitness and sociality measures used, and major climatic conditions of study sites explained any variation in direct fitness effect size. 5. We found group living had modest, yet positive effects on direct fitness. This generally adaptive scenario was contingent not only upon breeding strategy and climate of study sites, but also on fitness measures examined. Thus, positive and significant effects characterized singular as opposed to plural breeding strategies. 6. We found more positive fitness effects on studies conducted in tropical as opposed to temperate or arid climates. More positive and significant effects were noted on studies that relied on group fecundity, male fecundity and offspring survival as measures of fitness. 7. To conclude, direct fitness consequences of mammalian group living are driven by interspecific differences in breeding strategy and climate conditions. Other factors not examined in this study, namely individual variation in

    Designing an intervention to increase physical activity is important to be based on the health care settings resources and be acceptable by the subject group. This study was designed to assess and compare the effect of the goal setting strategy with a group education method on increasing the physical activity of mothers of children aged 1 to 5. Mothers who had at least one child of 1-5 years were randomized into two groups. The effect of 1) goal-setting strategy and 2) group education method on increasing physical activity was assessed and compared 1 month and 3 months after the intervention. Also, the weight, height, body mass index (BMI), waist and hip circumference, and well-being were compared between the two groups before and after the intervention. Physical activity level increased significantly after the intervention in the goal-setting group and it was significantly different between the two groups after intervention (P goal-setting group after the intervention. In the group education method, only the well-being score improved significantly (P goal-setting strategy to boost physical activity, improving the state of well-being and decreasing BMI, waist, and hip circumference.

    Full Text Available From the frame of the European Higher Education Space an adaptation of teaching-learning process is being promoted by means of the pedagogical renewal, introducing into the class a major number of active or participative methodologies in order to provide students with a major autonomy in said process. This requires taking into account the incorporation of basic skills within university curriculum, especially “teamwork”. By means of group techniques students can acquire interpersonal and cognitive skills, as well as abilities that will enable them to face different group situations throughout their academic and professional career. These techniques are necessary not only as a methodological strategy in the classroom, but also as a reflection instrument for students to assess their behavior in group, with an aim to modify conduct strategies that make that relationship with others influences their learning process. Hence the importance of this ability to sensitize students positively for collective work. Thus using the research-action method in the academic classroom during one semester and making systematic intervention with different group techniques, we manage to present obtained results by means of an analysis of the qualitative data, where the selected instruments are group discussion and personal reflection.

    We discuss the decision-making frameworks for clinical trials with multiple co-primary endpoints in a group-sequential setting. The decision-making frameworks can account for flexibilities such as a varying number of analyses, equally or unequally spaced increments of information and fixed or adaptive Type I error allocation among endpoints. The frameworks can provide efficiency, i.e., potentially fewer trial participants, than the fixed sample size designs. We investigate the operating characteristics of the decision-making frameworks and provide guidance on constructing efficient group-sequential strategies in clinical trials with multiple co-primary endpoints.

    2017-09-13

    Church-based interventions have been used to reach racial/ethnic minorities. In order to develop effective programs, we conducted a comprehensive systematic review of faith-based cancer prevention studies (2005~2016) to examine characteristics and promising strategies. Combination terms "church or faith-based or religion," "intervention or program," and "cancer education or lifestyle" were used in searching the five major databases: CINAHL; ERIC; Health Technology Assessments; MEDLINE; and PsycInfo. A total of 20 studies met study criteria. CDC's Community Guide was used to analyze and review group interventions. Analyses were organized by two racial groups: African American (AA) and Latino/Hispanic American groups. Results showed most studies reviewed focused on breast cancer alone or in combination with other cancers. Studies of Latino/Hispanic groups targeted more on uninsured, Medicare, or Medicaid individuals, whereas AA studies generally did not include specific insurance criteria. The sample sizes of the AA studies were generally larger. The majority of these studies reviewed used pre-post, posttest only with control group, or quasi-experience designs. The Health Belief Model was the most commonly used theory in both groups. Community-based participatory research and empowerment/ecological frameworks were also used frequently in the Latino/Hispanic studies. Small media and group education were the top two most popular intervention strategies in both groups. Although one-on-one strategy was used in some Latino studies, neither group used reducing client out-of-pocket costs strategy. Client reminders could also be used more in both groups as well. Current review showed church-based cancer education programs were effective in changing knowledge, but not always screening utilization. Results show faith-based cancer educational interventions are promising. To maximize intervention impact, future studies might consider using stronger study designs, incorporating a

    The considerable physical demand placed on the upper extremity during manual wheelchair propulsion is distributed among individual muscles. The strategy used to distribute the workload is likely influenced by the relative force-generating capacities of individual muscles, and some strategies may be associated with a higher injury risk than others. The objective of this study was to use forward dynamics simulations of manual wheelchair propulsion to identify compensatory strategies that can be used to overcome weakness in individual muscle groups and identify specific strategies that may increase injury risk. Identifying these strategies can provide rationale for the design of targeted rehabilitation programs aimed at preventing the development of pain and injury in manual wheelchair users. Muscle-actuated forward dynamics simulations of manual wheelchair propulsion were analyzed to identify compensatory strategies in response to individual muscle group weakness using individual muscle mechanical power and stress as measures of upper extremity demand. The simulation analyses found the upper extremity to be robust to weakness in any single muscle group as the remaining groups were able to compensate and restore normal propulsion mechanics. The rotator cuff muscles experienced relatively high muscle stress levels and exhibited compensatory relationships with the deltoid muscles. These results underline the importance of strengthening the rotator cuff muscles and supporting muscles whose contributions do not increase the potential for impingement (i.e., the thoracohumeral depressors) and minimize the risk of upper extremity injury in manual wheelchair users.

    The energy cost of self-maintenance is a critical facet of life-history strategies. Clarifying the determinant of interspecific variation in metabolic rate (MR) at rest is important to understand and predict ecological patterns such as species distributions or responses to climatic changes. We examined variation of MR in snakes, a group characterized by a remarkable diversity of activity rates and a wide distribution. We collated previously published MR data ( n = 491 observations) measured in 90 snake species at different trial temperatures. We tested for the effects of metabolic state (standard MR (SMR) versus resting MR (RMR)), foraging mode (active versus ambush foragers) and climate (temperature and precipitation) while accounting for non-independence owing to phylogeny, body mass and thermal dependence. We found that RMR was 40% higher than SMR, and that active foragers have higher MR than species that ambush their prey. We found that MR was higher in cold environments, supporting the metabolic cold adaptation hypothesis. We also found an additive and positive effect of precipitation on MR suggesting that lower MR in arid environments may decrease dehydration and energetic costs. Altogether, our findings underline the complex influences of climate and foraging mode on MR and emphasize the relevance of these facets to understand the physiological impact of climate change. © 2017 The Author(s).

    Anxiety about memory during menopause can affect quality of life. We aimed to improve memory self-efficacy during menopause using a group memory strategies program. The program was run five times for a total of 32 peri- and postmenopausal women, age between 47 and 60 years, recruited from hospital menopause and gynecology clinics. The 4-week intervention consisted of weekly 2-hour sessions, and covered how memory works, memory changes related to ageing, health and lifestyle factors, and specific memory strategies. Memory contentment (CT), reported frequency of forgetting (FF), use of memory strategies, psychological distress, and attitude toward menopause were measured. A double-baseline design was applied, with outcomes measured on two baseline occasions (1-month prior [T1] and in the first session [T2]), immediately postintervention (T3), and 3-month postintervention (T4). To describe changes in each variable between time points paired sample t tests were conducted. Mixed-effects models comparing the means of random slopes from T2 to T3 with those from T1 to T2 were conducted for each variable to test for treatment effects. Examination of the naturalistic changes in outcome measures from T1 to T2 revealed no significant changes (all Ps > 0.05). CT, reported FF, and use of memory strategies improved significantly more from T2 to T3, than from T1 to T2 (all Ps attitude toward menopause nor psychological distress improved significantly more postintervention than during the double-baseline (all Ps > 0.05). Improvements in reported CT and FF were maintained after 3 months. The use of group interventions to improve memory self-efficacy during menopause warrants continued evaluation.

    Moving a specific nursing health policy agenda forward depends on skill in building coalitions with other interest or stakeholder groups, including consumers. Often, nursing students study health policy in a discipline-specific environment without experiential opportunities to argue their views with other stakeholders in policy arenas. The health policy pathfinder, an innovative learning strategy for understanding interest group politics, will assist nursing students in meeting the following objectives: 1) analyze and articulate diverse policy arguments from various stakeholder groups; 2) identify opportunities for collaborations between stakeholder groups; 3) identify the influence of interest groups on the policy making process; and 4) critically evaluate evidence from a variety of sources ranging from peer-reviewed publications to grey literature to Internet blogs. This article describes the health policy pathfinder, including design, execution, and evaluation steps, and provides a brief excerpt from a student pathfinder. Copyright 2009, SLACK Incorporated.

Surveys assessing attitudes toward donation have shown that African Americans are less likely to express a willingness to donate their own organs. Studies aimed at understanding factors that may facilitate the willingness of African Americans to become organ donors are needed. Design, setting, participants, & measurements A novel formative research method was used (the nominal group technique) to identify and prioritize strategies for facilitating increases in organ donation among church-attending African Americans. Four nominal group technique panel interviews were convened (three community and one clergy). Each community panel represented a distinct local church; the clergy panel represented five distinct faith-based denominations. Before nominal group technique interviews, participants completed a questionnaire that assessed willingness to become a donor; 28 African-American adults (≥19 years old) participated in the study. Results In total, 66.7% of participants identified knowledge- or education-related strategies as most important strategies in facilitating willingness to become an organ donor, a view that was even more pronounced among clergy. Three of four nominal group technique panels rated a knowledge-based strategy as the most important and included strategies, such as information on donor involvement and donation-related risks; 29.6% of participants indicated that they disagreed with deceased donation, and 37% of participants disagreed with living donation. Community participants’ reservations about becoming an organ donor were similar for living (38.1%) and deceased (33.4%) donation; in contrast, clergy participants were more likely to express reservations about living donation (33.3% versus 16.7%). Conclusions These data indicate a greater opposition to living donation compared with donation after one’s death

    The purpose of this study is to examine the effect of two strategies for negotiating the question for exploration during science inquiry on student achievement and teachers' perceptions. The study is set in the context of the Science Writing Heuristic. The first strategy (small group) consisted of each group of four students negotiating a question for inquiry with the teacher while the second strategy (whole class) consisted of the entire class negotiating a single question for inquiry with the teacher. The study utilized a mixed-method approach. A quasi-experimental repeated measures design was used to determine the effect of strategy on student achievement and semi-structured teacher interviews were used to probe the question of teacher perceptions of the two strategies. Teacher observations were conducted using the Reformed Teaching Observation Protocol (RTOP) to check for variation in implementation of the two strategies. Iowa Test of Basic Skills Science (ITBSS) (2005 and 2006) and teacher/researcher developed unit exams (pre and post) were used as student achievement measures. No statistically significant differences were found among students in the two treatment groups on the ITBSS or unit exams. RTOP observations suggest that teacher implementation was consistent across the two treatment strategies. Teachers disclosed personal preferences for the two strategies, indicating the whole class treatment was easier to manage (at least at the beginning of the school year) as students gained experience with science inquiry and the associated increased responsibility. Possible mechanisms linking the two strategies, negotiated questions, and student outcomes are discussed.

    Full Text Available Abstract Background In order to improve treatments for cannabis use disorder, a better understanding of factors associated with successful quitting is required. Method This study examined differences between successful (n = 87 and unsuccessful (n = 78 cannabis quitters. Participants completed a questionnaire addressing demographic, mental health, and cannabis-related variables, as well as quitting strategies during their most recent quit attempt. Results Eighteen strategies derived from cognitive behavioral therapy were entered into a principal components analysis. The analysis yielded four components, representing (1 Stimulus Removal, (2 Motivation Enhancement, (3 (lack of Distraction, and (4 (lack of Coping. Between groups comparisons showed that unsuccessful quitters scored significantly higher on Motivation Enhancement and (lack of Coping. This may indicate that unsuccessful quitters focus on the desire to quit, but do not sufficiently plan strategies for coping. Unsuccessful quitters also had significantly more symptoms of depression and stress; less education; lower exposure to formal treatment; higher day-to-day exposure to other cannabis users; and higher cannabis dependence scores. Conclusions The findings suggest that coping, environmental modification, and co-morbid mental health problems may be important factors to emphasize in treatments for cannabis use disorder.

    Few studies have analyzed the strategies of neotropical tree seedlings for absorbing, translocating and assimilating the nitrogen. Here, we compared the nitrogen use strategies of seedlings from six tree species that are native to the Brazilian Atlantic Forest and that belong to different successional groups: Trema micrantha, Heliocarpus popayanensis and Cecropia pachystachya (pioneers), Cariniana estrellensis, Eugenia brasiliensis and Guarea kunthiana (non-pioneers). The effects of cultivating seedlings with nitrate or ammonium on the growth, physiology and nitrogen metabolism were analyzed. Nitrate-grown pioneer species had much higher leaf nitrate reductase activity than non-pioneer ones, but non-pioneer seedlings were also able to use nitrate as a nitrogen source. In addition to this remarkable difference between the groups in the capacity for leaf nitrate assimilation, substantial variations in the nitrogen use strategies were observed within the successional classes. Differently from the other non-pioneers, the canopy species C. estrellensis seemed to assimilate nitrate mainly in the leaves. Morphophysiological analyses showed a gradient of ammonium toxicity response, with E. brasiliensis as the most tolerant species, and T. micrantha and H. popayanensis as the most sensitive ones. Guarea kunthiana showed a relatively low tolerance to ammonium and an unusual high translocation of this cation in the xylem sap. In contrast to the other pioneers, C. pachystachya had a high plasticity in the use of nitrogen sources. Overall, these results suggest that nitrogen use strategies of neotropical tree seedlings were not determined solely by their successional position. Copyright © 2017 Elsevier Masson SAS.

    Globally, students with top academic performance and high intellectual capacity usually opt to study medicine. However, once students get enrolled, their academic performance varies widely. Such variations appear to be determined by various factors, one of them being types of learning strategies adopted by students. The learning strategies utilized by the students with better academic performance are likely to be more effective learning strategies. The objective is to identify effective learning strategies used by medical students. This study was carried out among the MBBS students of Final Professional Part I. Students were categorized into three groups namely: high, average, and low rankers based on overall academic performance in second Professional University examination. First, a questionnaire consisting of closed- and open-ended questions was administered to students, to find their learning strategies. Subsequently, focus group discussion and in-depth interviews were conducted for high- and low-rankers. Discussions were audio-recorded, transcribed, and analyzed. Key statements were highlighted, collated, and categorized into general themes and sub-themes. Evident themes which emerged as effective strategies were hard work in the form of regularity of studies, meticulous preparation of notes, constructive use of time, utilization of e-learning, learning styles and deep learning approach and regular ward visits. Intrinsic motivation, family support, balancing physical activities and studies, guidance by seniors, teachers, dealing with nonacademic issues such as language barriers and stress were also identified as important strategies. Disseminating effective learning strategies in a systematic manner may be helpful to students in achieving better academic outcomes. Furthermore, educationists need to modulate their teaching strategies based on students' feedback.

    Governments are promoting the importance of maintaining cognitive health into older age to minimize risk of cognitive decline and dementia. Older people with amnestic mild cognitive impairment (aMCI) are particularly vulnerable to memory challenges in daily activities and are seeking ways to maintain independent living. To evaluate the effectiveness of memory groups for improving memory strategies and memory ability of older people, especially those with aMCI. 113 healthy older adults (HOA) and 106 adults with aMCI were randomized to a six-week memory group or a waitlist control condition. Outcome was evaluated through knowledge and use of memory strategies, memory ability (self-report and neuropsychological tests), and wellbeing. Assessments included a six-month follow-up. Using intention to treat analyses, there were intervention effects for HOA and aMCI groups in strategy knowledge (HOA: η2= 0.20; aMCI: η2= 0.06), strategy use (HOA: η2= 0.18; aMCI: η2= 0.08), and wellbeing (HOA: η2= 0.11; aMCI: η2= 0.05). There were also intervention effects in the HOA group, but not the aMCI group, in self-reported memory ability (η2= 0.06) and prospective memory tests (η2= 0.02). By six-month follow-up, gains were found on most HOA outcomes. In the aMCI group gains were found in strategy use, and by this stage, gains in prospective memory were also found. Memory groups can engage older people in techniques for maintaining cognitive health and improve memory performance, but more modest benefits are seen for older adults with aMCI.

  1. Prey detection and prey capture in copepod nauplii.

    Directory of Open Access Journals (Sweden)

    Eleonora Bruno

    Full Text Available Copepod nauplii are either ambush feeders that feed on motile prey or they produce a feeding current that entrains prey cells. It is unclear how ambush and feeding-current feeding nauplii perceive and capture prey. Attack jumps in ambush feeding nauplii should not be feasible at low Reynolds numbers due to the thick viscous boundary layer surrounding the attacking nauplius. We use high-speed video to describe the detection and capture of phytoplankton prey by the nauplii of two ambush feeding species (Acartia tonsa and Oithona davisae and by the nauplii of one feeding-current feeding species (Temora longicornis. We demonstrate that the ambush feeders both detect motile prey remotely. Prey detection elicits an attack jump, but the jump is not directly towards the prey, such as has been described for adult copepods. Rather, the nauplius jumps past the prey and sets up an intermittent feeding current that pulls in the prey from behind towards the mouth. The feeding-current feeding nauplius detects prey arriving in the feeding current but only when the prey is intercepted by the setae on the feeding appendages. This elicits an altered motion pattern of the feeding appendages that draws in the prey.

    Full Text Available The rapid development of technology influence people‘s life in many aspects including the process of teaching and learning in university, school etc. Some social medias are popular in society, one of them is Facebook. This social networking can be used for any purposes Such as interacting, marketing, publishing, learning etc. The study aims to prove whether Facebook‘s group discussion can be effectively used to improve reading strategies which are normally developed through classroom interaction. It is an action research design involving one group consisting of 37 students randomly sampled out from a population of 198 students. A plan-act-observe-reflect design of the study will be carried out in two cycles. Each cycle involves pretest, treatment and post test. Cycle 1 is undertaken to see if there is a significant difference between the pretest and post test upon treatment. The indicator of success of the treatment is that the post test outscores the pretest. If it does, then Cycle 2 will be conducted to convince the results. If the two cycles show an increase in the mean scores, it can be claimed that the method is effective. In other words, Facebook‘s group discussion can be effectively used to improve reading strategies.

    Pricing strategies are mentioned frequently as a potentially effective tool to stimulate healthy eating, mainly for consumers with a low socio-economic status. Still, it is not known how these consumers perceive pricing strategies, which pricing strategies are favoured and what contextual factors are important in achieving the anticipated effects. We conducted seven focus groups among 59 residents of deprived neighbourhoods in two large Dutch cities. The focus group topics were based on insights from Rogers' Diffusion of Innovations Theory and consisted of four parts: 1) discussion on factors in food selection; 2) attitudes and perceptions towards food prices; 3) thinking up pricing strategies; 4) attitudes and perceptions regarding nine pricing strategies that were nominated by experts in a former Delphi Study. Analyses were conducted with Atlas.ti 5.2 computer software, using the framework approach. Qualitative analyses revealed that this group of consumers consider price to be a core factor in food choice and that they experience financial barriers against buying certain foods. Price was also experienced as a proficient tool to stimulate healthier food choices. Yet, consumers indicated that significant effects could only be achieved by combining price with information and promotion techniques. In general, pricing strategies focusing on encouraging healthy eating were valued to be more helpful than pricing strategies which focused on discouraging unhealthy eating. Suggested high reward strategies were: reducing the price of healthier options of comparable products (e.g., whole meal bread) compared to unhealthier options (e.g., white bread); providing a healthy food discount card for low-income groups; and combining price discounts on healthier foods with other marketing techniques such as displaying cheap and healthy foods at the cash desk. This focus group study provides important new insights regarding the use of pricing strategies to stimulate healthy eating

    Full Text Available This paper deals with the study of vulnerable groups in different educational institutions from the Bolivar Province. The research is based on the social pedagogical approach. Some risks may influence negatively in some groups, and in the teaching-learning process. That´s why, we diagnosed the most vulnerable educational institutions in the main communities and analyzed the causes influencing in this problematic, so we applied a survey and an observational guide to gather information. As a result we detected some students with educational vulnerability caused by dysfunctional families, the great distances from their schools, migration, poverty, physical and learning disabilities, and the fact that the teachers do not know how to deal with these problems. From the analysis and interpretations of the results of the empirical and theoretical methods we are elaborating a Didactic Guide containing learning and teaching strategies aimed at integrating vulnerable groups into different learning environments. Keywords:  educational vulnerability, strategies, learning environment, Social Pedagogy.

    2005-11-01

    A comprehensive assessment of possible strategies is the key step in a decommissioning process. It should be initiated at an early stage in a facility's lifecycle and include a number of factors. The IAEA has provided extensive guidance on decommissioning strategy selection, but there are a number of cases - particularly in countries with limited resources, but not limited to them - where the selection is forced and constrained by prevailing factors and conditions. In its role of an international expert committee assisting the IAEA, the Technical Group on Decommissioning (TEGDE) debates and draws conclusions on topics omitted from general guidance. TEGDE members met in Vienna in 2003, 2004 and 2005 to develop the basis for this publication. The views expressed here reflect those of TEGDE and not necessarily those of the IAEA

    Although peer-based work is encouraged by theories in developmental psychology and although classroom interventions suggest it is effective, there are grounds for recognising that young pupils find collaborative learning hard to sustain. Discontinuities in collaborative skill during development have been suggested as one interpretation. Theory and research have neglected situational continuities that the teacher may provide in management of formal and informal collaborations. This experimental study, with the collaboration of the science faculty in one urban secondary college, investigated the effect of two role attribution strategies on communication in peer groups of different gender composition in three parallel Year 8 science classes. The group were set a problem that required them to design an experiment to compare the thermal insulating properties of two different materials. This presents the data collected and key findings, and reviews the findings from previous parallel studies that have employed the same research design in different school settings. The results confirm the effectiveness of social role attribution strategies in teacher management of communication in peer-based work.

    Full Text Available Purpose: The purpose of this paper is to help business marketers with offline channels to make decisions on whether to sell through Group-buying (GB websites and how to set online price with the coordination of maximum deal size on GB websites. Design/methodology/approach: Considering the deal structure of GB websites especially for the service fee and minimum deal size limit required by GB websites, advertising effect of selling on GB websites, and interaction between online and offline markets, an analytical model is built to derive optimal online price and maximum deal size for sellers selling through GB website. This paper aims to answer four research questions: (1 How to make a decision on maximum deal size with coordination of the deal price? (2 Will selling on GB websites always be better than staying with offline channel only? (3 What kind of products is more appropriate to sell on GB website? (4How could GB website operator induce sellers to offer deep discount in GB deals? Findings and Originality/value: This paper obtains optimal strategies for sellers selling on GB website and finds that: Even if a seller has sufficient capacity, he/she may still set a maximum deal size on the GB deal to take advantage of Advertisement with Limited Availability (ALA effect; Selling through GB website may not bring a higher profit than selling only through offline channel when a GB site only has a small consumer base and/or if there is a big overlap between the online and offline markets; Low margin products are more suitable for being sold online with ALA strategies (LP-ALA or HP-ALA than high margin ones; A GB site operator could set a small minimum deal size to induce deep discounts from the sellers selling through GB deals. Research limitations/implications: The present study assumed that the demand function is determinate and linear. It will be interesting to study how stochastic demand and a more general demand function affect the optimal

    The development of a world-wide makeup foundation range requires a thorough understanding of skin color features of women around the world. To understand the cosmetic needs of women from different ethnic groups, we measured skin color in five different groups (French and American Caucasian, Japanese, African-American, and Hispanic-American) and compared the data obtained with women's self-perception of skin color, before or after applying their usual foundation product. Skin color was measured using a spectro-radiometer and a spheric lighting device with CCD camera ensuring a highly reliable imaging and data acquisition. The diversity of skin types involved in the study lead to define a large, continuous color space where color spectra from various ethnic groups overlap. Three types of complexion - dark, medium, or light - were distinguished in each group. Only Japanese women did not identify with this lightness scale and considered it makes more sense to classify their skin according to a pink-ocher-beige color scale. The approach however revealed the great variety of skin colors within each ethnic group and the extent of unevenness. A fairly good agreement appeared between women's self-perception and data from color measurements but in Hispanic-American group. Data recorded, after foundation was applied, showed overall consistency with makeup strategy as described by volunteers except for the latter group whose approach looked more uncertain and variable. The findings of the study demonstrate the advantage of combining qualitative and quantitative approach for assessing the cosmetic needs and expectations of women from different ethnic origin and cultural background.

    Why public information activities in Korea are needed is first explained. There are three basic reasons; 1) to secure necessary sites for construction of large nuclear facilities; such as nuclear power plants, radwaste management facilities, and nuclear fuel-cycle related facilities 2) to maintain a friendly relationship between the local communities and the nuclear industries, 3) to promote better understanding about the nation's peaceful nuclear programs to the various target groups. Categorization of target groups and messages are reviewed. By whom the public information programs are implemented is also explained. An orchestrated effort together with the third communicators is stressed. Basic philosophy of nuclear public information programs is introduced. A high-profile information campaign and a low-profile information campaign are explained. Particular information strategies suitable to Korean situation as examined. In addition, the Korean general public perception on nuclear energy is briefly introduced. Also, some real insights of anti-nuclear movement in Korea together with the arguments are reviewed. In conclusion, the paper stresses that nuclear arguments became no more technical matters but almost socio-political issues. (author)

    Full Text Available The cerrado's flora comprises aluminum-(Al accumulating and non-accumulating plants, which coexist on acidic and Al-rich soils with low fertility. Despite their existence, the ecological importance or biological strategies of these functional groups have been little explored. We evaluated the leaf flushing patterns of both groups throughout a year; leaf concentrations of N, P, K, Ca, Mg, S, Al, total flavonoids and polyphenols; as well as the specific leaf area (SLA on young and mature leaves within and between the groups. In Al-accumulating plants, leaf flushed throughout the year, mainly in May and September; for non-accumulating plants, leaf flushing peaked at the dry-wet seasons transition. However, these behaviors could not be associated with strategies for building up concentrations of defense compounds in leaves of any functional groups. Al-accumulating plants showed low leaf nutrient concentrations, while non-accumulating plants accumulated more macronutrients and produced leaves with high SLA since the juvenile leaf phase. This demonstrates that the increase in SLA is slower in Al-accumulating plants that are likely to achieve SLA values comparable to the rest of the plant community only in the wet season, when sunlight capture is important for the growth of new branches.

    To evaluate dispositional coping strategies as predictors for changes in well-being after 1 year in older patients with cancer (OCP) and 2 control groups. OCP were compared with 2 control groups: middle-aged patients with cancer (MCP) (aging effect) and older patients without cancer (ONC) (cancer effect). Patients were interviewed shortly after a cancer diagnosis and 1 year later. Dispositional coping was measured with the Short Utrecht Coping List. For well-being, we considered psychological well-being (depression, loneliness, distress) and physical health (fatigue, ADL, IADL). Logistic regression analyses were performed to study baseline coping as predictor for subsequent well-being while controlling for important baseline covariates. A total of 1245 patients were included in the analysis at baseline: 263 OCP, 590 ONC, and 392 MCP. Overall, active tackling was employed most often. With the exception of palliative reacting, OCP utilized each coping strategy less frequently than MCP. At 1-year follow-up, 833 patients (66.9%) were interviewed. Active coping strategies (active tackling and seeking social support) predicted subsequent well-being only in MCP. Avoidance coping strategies did not predict well-being in any of the patient groups. Palliative reacting predicted distress in OCP; depression and dependency for ADL in MCP. Coping strategies influence subsequent well-being in patients with cancer, but the impact is different in the age groups. Palliative reacting was the only coping strategy that predicted well-being (ie, distress) in OCP and is therefore, especially in this population, a target for coping skill interventions.

    2017-12-01

    In laboratory experiments, we investigated how media with varying ratio of peat:sand and two levels of compaction influence dispersal success of entomopathogenic nematode (EPN) species with different foraging strategies: Steinernema carpocapsae (ambusher), Heterorhabditis downesi (cruiser) and Steinernema feltiae (intermediate). Success was measured by the numbers of nematodes moving through a 4 cm column and invading a wax moth larva. We found that both compaction and increasing peat content generally decreased EPN infective juvenile (IJ) success for all three species. Of the three species, H. downesi was the least affected by peat content, and S. carpocapsae was the most adversely influenced by compaction. In addition, sex ratios of the invading IJs of the two Steinernema species were differentially influenced by peat content, and in the case of S. feltiae, sex ratio was also affected by compaction. This indicates that dispersal of male and female IJs is differentially affected by soil parameters and that this differentiation is species-specific. In conclusion, our study shows that organic matter: sand ratio and soil compaction have a marked influence on EPN foraging behaviour with implications for harnessing them as biological pest control agents.

    2013-04-01

    A large increase of pertussis incidence has been observed in recent years in countries with high vaccination coverage. Outbreaks of pertussis are increasingly being reported. The age presentation has a bipolar distribution: infants younger 6months that have not initiated or completed a vaccination schedule, and adolescents and adults, due to the lost of natural or vaccine immunity over time. These epidemiological changes justify the need to adopt new vaccination strategies in order to protect young infants and to reduce pertussis incidence in all age groups. Adolescents and adults immunization must be a priority. In the first group, strategy is easy to implement, and with a very low additional cost (to replace dT vaccine by dTap one). Adult vaccination may be more difficult to implement; dT vaccine decennial booster should be replaced by dTap. The immunization of household contacts of newborn infants (cocooning) is the strategy that has a most important impact on infant pertussis. Recently, pregnant women vaccination (after 20weeks of gestation) has been recommended in some countries as the most effective way to protect the newborn. Copyright © 2012 Elsevier España, S.L.

  3. Offensive Strategy in the 2D Soccer Simulation League Using Multi-Group Ant Colony Optimization

    2016-02-01

    Full Text Available The 2D soccer simulation league is one of the best test beds for the research of artificial intelligence (AI. It has achieved great successes in the domain of multi-agent cooperation and machine learning. However, the problem of integral offensive strategy has not been solved because of the dynamic and unpredictable nature of the environment. In this paper, we present a novel offensive strategy based on multi-group ant colony optimization (MACO-OS. The strategy uses the pheromone evaporation mechanism to count the preference value of each attack action in different environments, and saves the values of success rate and preference in an attack information tree in the background. The decision module of the attacker then selects the best attack action according to the preference value. The MACO-OS approach has been successfully implemented in our 2D soccer simulation team in RoboCup competitions. The experimental results have indicated that the agents developed with this strategy, along with related techniques, delivered outstanding performances.

    The Late Triassic freshwater ecosystems were occupied by different tetrapod groups including large-sized anamniotes, such as metoposaurids. Most members of this group of temnospondyls acquired gigantic sizes (up to 5 m long) with a nearly worldwide distribution. The paleoecology of metoposaurids is controversial; they have been historically considered passive, bottom-dwelling animals, waiting for prey on the bottom of rivers and lakes, or they have been suggested to be active mid-water feeders. The present study aims to expand upon the paleoecological interpretations of these animals using 3D finite element analyses (FEA). Skulls from two taxa, Metoposaurus krasiejowensis, a gigantic taxon from Europe, and Apachesaurus gregorii, a non-gigantic taxon from North America, were analyzed under different biomechanical scenarios. Both 3D models of the skulls were scaled to allow comparisons between them and reveal that the general stress distribution pattern found in both taxa is clearly similar in all scenarios. In light of our results, both previous hypotheses about the paleoecology of these animals can be partly merged: metoposaurids probably were ambush and active predators, but not the top predators of these aquatic environments. The FEA results demonstrate that they were particularly efficient at bilateral biting, and together with their characteristically anteropositioned orbits, optimal for an ambush strategy. Nonetheless, the results also show that these animals were capable of lateral strikes of the head, suggesting active hunting of prey. Regarding the important skull size differences between the taxa analyzed, our results suggest that the size reduction in the North American taxon could be related to drastic environmental changes or the increase of competitors. The size reduction might have helped them expand into new ecological niches, but they likely remained fully aquatic, as are all other metoposaurids. © 2017 Anatomical Society.

  5. Dietary analysis of Homonota darwini (Squamata: Gekkoni-dae in Northern Patagonia

    Full Text Available Our study investigated the diet of the southernmost gecko in the world, Homonota darwini. Fifty-three specimens were captured during spring and summer in four locations in Patagonia, Argentina. The stomach contents of the specimens were identified, and we found that prey consisted of six main groups: Coleoptera, Hymenoptera, Homoptera and Araneae, and the adults and larvae of moth Lepidoptera. Lepidoptera was the major dietary component. The presence of ants and moths as common prey suggests an ambush feeding strategy. In spring, females consumed more ants than males although no other dietary differences between males and females were evident. We found nine geckos with empty stomachs and six parasitized by nematodes. Presence of empty stomachs corroborates previous observations of other nocturnal geckos and non-gecko lizards. Reduced foraging success of nocturnal lizards could be due to difficulty in prey detection due to dim light, reduced or erratic activity of insect prey at night, or shorter activity times of geckos relative to diurnal success. Sex and season were not associated with the incidence of empty stomachs. Principal component analysis showed that four food alternatives correlated with season. The constraint of nocturnality, coupled with low night-time temperatures restricting feeding to only a few hours after sunset, appear to have caused a generality of diet which may limit energy acquisition. We conclude that H. darwini is an arthropod generalist and likely an ambush forager, as are many other nocturnal gekkonids [Current Zoology 56 (4: 406–410, 2010].

    Full Text Available Background The present study aimed to investigate personality traits and coping strategies in patients with multiple sclerosis (MS who were admitted to Sina hospital compared with healthy individuals. Objectives The aim of the present study was to compare personality characteristics and coping strategies between patients with MS and healthy controls. Materials and Methods The study sample included 55 patients with MS and 57 matched healthy control individuals. The data were gathered via a demographic form, the ways of coping questionnaire, and the NEO five-factor inventory. The data were analyzed by multivariate analysis of variance (MANOVA, Pearson’s correlation coefficient, and logistic regression. Results No significant differences in personality characteristics were observed between patients and healthy controls (all P > 0.05. Only the coping strategy subscale of Distancing was significant between patients and healthy controls (P 0.05. Only the Neuroticism personality trait and the Distancing coping strategy were predictive of group membership (i.e., healthy or patient. Conclusions Our study suggests that the personality traits of patients with MS and healthy individuals are not significantly different. Patients with MS are likely to use the same coping strategies as healthy individuals, except in the subscale of Distancing.

    2015-03-01

    This study has determined the extents and basis for variations in the composition of the prey ingested by the abundant species of a family highly adapted for ambush predation, i.e. Platycephalidae, in a region (south-western Australia) where that family is found in different habitats and environments. Dietary data were thus collected for Leviprora inops and Platycephalus laevigatus from seagrass in marine embayments and for Platycephalus westraliae from over sand in an estuary. These were then collated with those recorded previously for Platycephalus speculator from over sand and in seagrass in an estuary and for Platycephalus longispinis from over sand in coastal marine waters. While crustaceans and teleosts together dominated the diet of all five species, their percentage volumetric dietary contributions varied greatly, with those of crustaceans ranging from 7% for L. inops to 65% for P. speculator and those of teleosts ranging from 29% for P. longispinis to 91% for L. inops. For analyses, the data were separated into two sets. The first comprised the 17 dietary categories of invertebrates and all identified and unidentified teleosts collectively, while the second consisted of the 23 identified teleost families, both of which were subjected to permutational analysis of variance (PERMANOVA), analysis of similarities (ANOSIM) and a new (two-way) version of the RELATE procedure. The diets of three species changed seasonally, when using invertebrate dietary categories and teleosts collectively, but with only one species, when employing identified teleost families, probably reflecting a greater tendency for invertebrate than teleost prey abundance to change during the year. On the basis of dietary data for invertebrate taxa + teleosts collectively, the diets of three of the five species changed serially with body size, with a fourth species feeding, throughout life, predominantly on the carid Palaemonetes australis. Based on identified teleost families, the diets of

    Entomopathogenic nematodes (EPNs) respond to a variety of stimuli when foraging. In a laboratory investigation, we tested the chemotactic responses of 8 EPN strains (Steinernema and Heterorhabditis) to three mechanically damaged maize root compounds (linalool, α-caryophyllene and β-caryophyllene). We hypothesized that the EPN directional response to the tested volatile compounds would vary among the species and volatile compound and may be related to foraging strategies. The nematodes with an intermediate foraging strategy (Steinernema feltiae) proved to be less active in their movement toward volatile compounds in a comparison with the ambushers (Steinernema carpocapsae) and cruisers (Steinernema kraussei and Heterorhabditis bacteriophora); β-caryophyllene was found to be the most attractive substance in our experiment. The results of our investigation showed that the cruisers were more attracted to β-caryophyllene than the ambushers and intermediates. The foraging strategy did not affect the movement of the IJs toward the other tested volatile compounds or the control. Our results suggest that the response to different volatile cues is more a strain-specific characteristic than a different host-searching strategy. Only S. carpocapsae strain B49 displayed an attraction to linalool, whereas S. kraussei showed a retarded reaction to β-caryophyllene and α-caryophyllene in our experiment. The EPN strains showed only a weak attraction to α-caryophyllene, suggesting that this volatile compound could not have an important role in the orientation of IJs to the damaged roots of maize plants. These results expand our knowledge of volatile compounds as the cues that may be used by EPNs for finding hosts or other aspects of navigation in the soil. Copyright © 2013 Elsevier Inc.

    As consolidation sweeps over the healthcare industry, many medical groups are considering mergers with other groups as an alternative to employment. While mergers are challenging and fraught with risk, an organized approach to the merger process can dramatically increase the odds for success. Merging groups need to consider the benefits they seek from a merger, identify the obstacles that must be overcome to merge, and develop alternatives to overcome those obstacles. This article addresses the benefits to be gained and issues to be addressed, and provides a tested roadmap that has resulted in many successful medical group mergers.

    2011-01-01

    Nurse researchers and educators often engage in outreach to narrowly defined populations. This article offers examples of how variations on the snowball sampling recruitment strategy can be applied in the creation of culturally appropriate, community-based information dissemination efforts related to recruitment to health education programs and research studies. Examples from the primary author’s program of research are provided to demonstrate how adaptations of snowball sampling can be effectively used in the recruitment of members of traditionally underserved or vulnerable populations. The adaptation of snowball sampling techniques, as described in this article, helped the authors to gain access to each of the more vulnerable population groups of interest. The use of culturally sensitive recruitment strategies is both appropriate and effective in enlisting the involvement of members of vulnerable populations. Adaptations of snowball sampling strategies should be considered when recruiting participants for education programs or subjects for research studies when recruitment of a population based sample is not essential.

    A computer model, SOURCE, has been developed to study the impact of convoy configuration and tactics upon personnel survival and emergency signal generation during an initial armed attack. During this quarter, several improvements were made to the SOURCE code. These improvements include (1) the capability to model an ambush in which the adversaries set up a roadblock, (2) upgraded data on aiming accuracies and human vulnerabilities, and (3) two output formats for examining the locations of the surviving guards. To support the conflict analysis task, several complementary conflict modeling efforts are undergoing parallel development. These methodologies include the SABRES computerized conflict simulation models, the AMBUSH conflict board game, and an alternative methodology being developed by Vector Research, Inc. (VRI). The SABRES I combat model can be used to study the relative value of alternative defender tactics and the relative value of different weapon systems. AMBUSH is a tactical board game which provides a hypothetical conflict between a truck convoy and an adversary group attempting a hijacking. ORINCON Corporation developed network models to be used in determining the cost implications of alternative transportation regulations. SRI International provided weapon characterization data from representative types and calibers of sporting rifles, assault rifles, machine guns, submachine guns, shotguns, and handguns. The alternative methodology for conflict modeling being developed by VRI is the engagement model, CONVOY. SAI is under contract to model the communication system for transporters of SNM

    Directory of Open Access Journals (Sweden)

    Shunyi Li

    2013-01-01

    Full Text Available A predator-prey system with generalized group defense and impulsive control strategy is investigated. By using Floquet theorem and small amplitude perturbation skills, a local asymptotically stable prey-eradication periodic solution is obtained when the impulsive period is less than some critical value. Otherwise, the system is permanent if the impulsive period is larger than the critical value. By using bifurcation theory, we show the existence and stability of positive periodic solution when the pest eradication lost its stability. Numerical examples show that the system considered has more complicated dynamics, including (1 high-order quasiperiodic and periodic oscillation, (2 period-doubling and halving bifurcation, (3 nonunique dynamics (meaning that several attractors coexist, and (4 chaos and attractor crisis. Further, the importance of the impulsive period, the released amount of mature predators and the degree of group defense effect are discussed. Finally, the biological implications of the results and the impulsive control strategy are discussed.

    Described is a new hydrazone-based exo-directing group (DG) strategy developed for the functionalization of unactivated primary β C-H bonds of aliphatic amines. Conveniently synthesized from protected primary amines, the hydrazone DGs are shown to site-selectively promote the β-acetoxylation and tosyloxylation via five-membered exo-palladacycles. Amines with a wide scope of skeletons and functional groups are tolerated. Moreover, the hydrazone DG can be readily removed, and a one-pot C-H acetoxylation/DG removal protocol was also discovered. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2014-01-01

    Background This study aims to review the literature regarding the barriers to sampling, recruitment, participation, and retention of members of socioeconomically disadvantaged groups in health research and strategies for increasing the amount of health research conducted with socially disadvantaged groups. Methods A systematic review with narrative synthesis was conducted. Searches of electronic databases Medline, PsychInfo, EMBASE, Social Science Index via Web of Knowledge and CINHAL were conducted for English language articles published up to May 2013. Qualitative and quantitative studies as well as literature reviews were included. Articles were included if they reported attempts to increase disadvantaged group participation in research, or the barriers to research with disadvantaged groups. Groups of interest were those described as socially, culturally or financially disadvantaged compared to the majority of society. Eligible articles were categorised according to five phases of research: 1) sampling, 2) recruitment and gaining consent, 3) data collection and measurement, 4) intervention delivery and uptake, and 5) retention and attrition. Results In total, 116 papers from 115 studies met inclusion criteria and 31 previous literature reviews were included. A comprehensive summation of the major barriers to working with various disadvantaged groups is provided, along with proposed strategies for addressing each of the identified types of barriers. Most studies of strategies to address the barriers were of a descriptive nature and only nine studies reported the results of randomised trials. Conclusions To tackle the challenges of research with socially disadvantaged groups, and increase their representation in health and medical research, researchers and research institutions need to acknowledge extended timeframes, plan for higher resourcing costs and operate via community partnerships.

    2004-01-01

    In France, for several years, the Institute for Radiological Protection and Nuclear Safety (IRSN) has been working on technical solutions for the rehabilitation of rural, urban and industrial areas, contaminated by radioactivity. Then, the complexity of the radioactivity integration' s mechanisms into the environment and into the food chain, but also the important number of concerned actors and the inevitable incompatibilities between their respective expectations of the rehabilitation, make the post accidental management a challenging question for the responsible organisations at local, national and international levels. The involvement of persons in charge of agriculture in a collective reflection on the conditions and means of the post accidental situation's management seemed therefore necessary, in order to allow them to express the farmers point of view. On this basis, IRSN is deeply engaged in actions involving these other stakeholders, in particular in rural environment, in order to collect their appraisal and to obtain data and operational tools for the global evaluation of the countermeasures. The FARMING project, initiated in 2000 by the European Commission, constituted an interesting initiative in this direction. The French group has been constituted around the National Institute for Agronomy of Paris Grignon, which ensures its coordination. Within this framework, this group has notably been involved in the evaluation of a rural countermeasures compendium, at the request of STRATEGY, another European network on the post-accidental situation. With the support of a French farmers national association (FNSEA), the French FARMING group built up a working group composed of technical specialists of agriculture and radiation protection. All these actions facilitated the expression of the specific request for information, coming from the agricultural stakeholders, to the actors of radiation protection, and the design of new projects involving radiation

    Predators often employ a complex series of behaviors to overcome antipredator defenses and effectively capture prey. Although hunting behaviors can improve with age and experience, many precocial species are necessarily effective predators from birth. Additionally, many predators experience innate ontogenetic shifts in predatory strategies as they grow, allowing them to adapt to prey more appropriate for their increased size and energetic needs. Understanding how the relative roles of innate age-specific adaptation and learning have evolved requires information on how predation behavior develops in situ, in free-ranging predators. However, most of the research on the ontogeny of predation behavior is based on laboratory studies of captive animals, largely due to the difficulty of following newborn individuals in nature. Here, we take advantage of the unique tracks left by juveniles of a precocial viperid, the sidewinder rattlesnake (Crotalus cerastes), which we used to follow free-ranging snakes in the field. We recorded details of their ambush hunting behavior, and compared the behaviors of these juveniles to adult snakes that we monitored in the field via radio telemetry. Although juvenile and adult behaviors were similar in most respects, we did find that adults chose more effective ambush sites, which may be due to their increased experience. We also found that juveniles (but typically not adults) perform periodic tail undulations while in ambush, and that juveniles displayed slightly different activity cycles. Both of these latter differences are likely the result of age-specific adaptations for juveniles' greater reliance on lizards versus small mammals as prey. We also compared the general predatory behavior of sidewinders to that of other species in the genus Crotalus. These findings will provide important baseline field information for more detailed empirical research on the ontogeny of predation behavior in precocial vertebrates. Copyright © 2016

    Until recently, periodic Group A meningococcal meningitis outbreaks were a major public health problem in the sub-Saharan Africa. In 2001, the Meningitis Vaccine Project (MVP), a partnership between the World Health Organization (WHO) and PATH, a Seattle-based NGO, and the Serum Institute of India Pvt Ltd (SIIPL) initiated discussions aimed at establishing a collaboration to develop a Group A meningococcal conjugate vaccine for this unmet medical need. Over the next 8 years the partnership made countless strategic decisions about product characteristics, raw materials, potential target populations, geographic prioritization and affordability of the vaccine to name a few. These decisions evolved into detailed plans for preclinical development, extensive field trials in Africa and India and a focused regulatory strategy specific for the Men A conjugate vaccine. Important characteristics of the process included, flexibility, transparency andeffective partnerships that included public agencies as well as private companies in Africa, Europe, the United States and India.

    Silvopastoral systems combine trees and/or shrubs with grazing cattle. In the municipality of Salto de Agua, Chiapas, Mexico, some indigenous communities have developed silvopastoral systems based on their traditional knowledge regarding use of local natural resources. Through analysis of classification based on the composition of tree vegetation, two groups of grazing units were identified in the study area. Different attributes of tree and herbaceous vegetation, as well as of agricultural management and production, were compared between the two groups. Results indicate that at least two strategies of silvopastoral management exist. The first - LTD - is characterized by an average density of 22 adult trees ha(-1) in grazing units with an average surface area of 22.4 ha. The second - HTD - has an average of 54.4 trees ha(-1) in grazing units with an average surface area of 12.2 ha. Average richness per grazing unit for the LTD strategy was 7.2 species, and for HTD strategy it was 12.7 species. Average basal area for LTD was 1.7 m2 ha(-1), and for HTD 3.8 m2 ha(-1). Finally, the average level of fixed carbon for LTD was 2.12 mg ha(-1), and for HTD 4.89 mg ha(-1). For all variables, there was a significant difference between the two strategies. In addition, both strategies differ in prairie management. In the HTD strategy, growers spare their preferred spontaneously growing tree species by clearing around them. Many of these species, particularly those harvested for timber, belong to the original vegetation. In these prairies, average coverage of native grasses (60.8 ± 7.85) was significantly greater than in the LTD strategy (38.4 ± 11.32), and neither fertilizers nor fire are used to maintain or improve the pastures; by contrast, in HTD prairies, introduced grasses, principally Cynodon plectostachyus, have a higher average coverage (43.4 ± 13.75) than in the LTD prairies (17.08 ± 9.02). Regardless of the differences in composition of tree and

    Full Text Available Thermoregulatory processes were compared among three-size groups of free-ranging Komodo dragons (Varanus komodoensis comprising small (5–20 kg, medium (20–40 gm and large (40–70 kg lizards. While all size groups maintained a similar preferred body temperature of ≈35∘C, they achieved this end point differently. Small dragons appeared to engage in sun shuttling behavior more vigorously than large dragons as represented by their greater frequency of daily ambient temperature and light intensity changes as well as a greater activity and overall exposure to the sun. Large dragons were more sedentary and sun shuttled less. Further, they appear to rely to a greater extent on microhabitat selection and employed mouth gaping evaporative cooling to maintain their preferred operational temperature and prevent overheating. A potential ecological consequence of size-specific thermoregulatory habits for dragons is separation of foraging areas. In part, differences in thermoregulation could contribute to inducing shifts in predatory strategies from active foraging in small dragons to more sedentary sit-and-wait ambush predators in adults.

    Boa constrictor is often referred to as a sit-and-wait or ambush forager that chooses locations to maximize the likelihood of prey encounters (Greene 1983. In Janzen [ed.], Costa Rica Natural History, pp. 380-382. Univ. Chicago Press, Illinois). However, as more is learned about the natural history of snakes in general, the dichotomy between active versus ambush foraging is becoming blurred. Herein, we describe an instance of diurnal active foraging by a B. constrictor, illustrating that this species exhibits a range of foraging behaviors.

    Ishii, Mamoru; Sun Xiaodong; Kim, Seungjin

    2003-01-01

    This paper presents the general strategy for modeling the source and sink terms in the two-group interfacial area transport equation. The two-group transport equation is applicable in bubbly, cap bubbly, slug, and churn-turbulent flow regimes to predict the change of the interfacial area concentration. This dynamic approach has an advantage of flow regime-independence over the conventional empirical correlation approach for the interfacial area concentration in the applications with the two-fluid model. In the two-group interfacial area transport equation, bubbles are categorized into two groups: spherical/distorted bubbles as Group 1 and cap/slug/churn-turbulent bubbles as Group 2. Thus, two sets of equations are used to describe the generation and destruction rates of bubble number density, void fraction, and interfacial area concentration for the two groups of bubbles due to bubble expansion and compression, coalescence and disintegration, and phase change. Based upon a detailed literature review of the research on the bubble interactions, five major bubble interaction mechanisms are identified for the gas-liquid two-phase flow of interest. A systematic integral approach, in which the significant variations of bubble volume and shape are accounted for, is suggested for the modeling of two-group bubble interactions. To obtain analytical forms for the various bubble interactions, a simplification is made for the bubble number density distribution function

    2016-04-01

    Conclusion: Based on the results, the group cognitive-behavioral therapy can increase the use of compatible strategies for coping with stress and decrease the use of incompatible strategies. This issue is related to factors such as complete understanding of Alzheimer’s disease and its effects, creating an atmosphere for presentation and an opportunity for social interaction, understanding the importance of sport and allocating time for recreational activities, learning body relaxation in stressful situations, understanding life problems, solving problem techniques, feeling of control, and time management. Thus, we recommend using group cognitivebehavioral therapy as a low-cost treatment for family caregivers of patients with Alzheimer’s and patients with chronic diseases.

    2012-08-01

    To assess the role that social contextual factors exert on the way people with disproportionate short stature (dwarfism) cope with the negative consequences of discrimination. Using multigroup structural equation modeling, we compare the coping process of people with dwarfism from Spain (N = 63) and the USA (N = 145), two countries that differ in the role played by organizations offering support to people with dwarfism. In Spain, where organizational support is recent, a coping approach aimed at achieving integration with the majority group through limb-lengthening surgery prevails; in the USA, where the long-standing organization of people with dwarfism encourages pride in being a "little person" and positive intragroup contact, a coping strategy based on empowering the minority group dominates. Both strategies, each in its own context, are effective at protecting psychological well-being from the negative consequences of stigmatization; however, they exert their positive effects through different processes.

    Most working adults with low back pain (LBP) continue to work despite pain, but few studies have assessed self-management strategies in this at-work population. The purpose of this study was to identify workplace challenges and self-management strategies reported by workers remaining at work despite recurrent or persistent LBP, to be used as a framework for the development of a workplace group intervention to prevent back disability. Workers with LBP (n = 38) participated in five focus groups, and audio recordings of sessions were analysed to assemble lists of common challenges and coping strategies. A separate analysis provided a general categorisation of major themes. Workplace pain challenges fell within four domains: activity interference, negative self-perceptions, interpersonal challenges and inflexibility of work. Self-management strategies consisted of modifying work activities and routines, reducing pain symptoms, using cognitive strategies and communicating pain effectively. Theme extraction identified six predominant themes: knowing your work setting, talking about pain, being prepared for a bad day, thoughts and emotions, keeping moving and finding leeway. To retain workers with LBP, this qualitative investigation suggests future intervention efforts should focus on worker communication and cognitions related to pain, pacing of work and employer efforts to provide leeway for altered job routines.

    Full Text Available Strengthening ongoing bottom-up capacity building processes for local and sustainable landscape-level governance is a multi-dimensional social endeavor. One of the tasks involved – participatory rural land use planning – requires more understanding and more awareness among all stakeholders regarding the social dilemmas local people confront when responding to each other’s land-use decisions. In this paper we will analyze and discuss a version of our game SIERRA SPRINGS that is simple to play for any stakeholder that can count to 24, yet entails a complex-coordination land use game – with an extensive and yet finite set of solutions – which can mimic in a stylized form some of the dilemmas landowners could confront in a landscape planning process where there livelihoods are at stake. The game has helped researchers and players observe and reflect on the individual coordination strategies that emerge within a group in response to these stylized dilemmas. This paper (1 develops a game-theoretical approach to cooperation, competition and coordination of land uses in small rural watersheds, (2 describe the goal, rules and mechanics of the game, (3 analyzes the structure of each farms’ solution set vs. the whole watershed’s solution set, (4 derives from them the coordination dilemmas and the risk of coordination failure, (5 describes four individual coordination strategies consistently displayed by players; mapping them in a plane we have called Group-Level Coordination Space, and (6 discusses the strengths, limitations and actual and potential uses of the game both for research and as an introductory tool for stakeholders involved in participatory land use planning.

    Hu, Haiyang; Wang, Qiang

    2018-07-01

    A new strategy for grouping spectral absorption coefficients, considering the influences of both temperature and species mole ratio inhomogeneities on correlated-k characteristics of the spectra of gas mixtures, has been deduced to match the calculation method of spectral overlap parameter used in multiscale multigroup wide band k-distribution model. By comparison with current spectral absorption coefficient grouping strategies, for which only the influence of temperature inhomogeneity on the correlated-k characteristics of spectra of single species was considered, the improvements in calculation accuracies resulting from the new grouping strategy were evaluated using a series of 0D cases in which radiance under 3-5-μm wave band emitted by hot combustion gas of hydrocarbon fuel was attenuated by atmosphere with quite different temperature and mole ratios of water vapor and carbon monoxide to carbon dioxide. Finally, evaluations are presented on the calculation of remote sensing thermal images of transonic hot jet exhausted from a chevron ejecting nozzle with solid wall cooling system.

  9. Dignity and Deferral Narratives as Strategies in Facilitated Technology-Based Support Groups for People with Advanced Cancer

    Directory of Open Access Journals (Sweden)

    Annette F. Street

    2012-01-01

    Full Text Available This paper examines the value of facilitated telephone and online support groups for palliative care. Telephone interviews were conducted with twenty people living with advanced cancer who had participated in either a telephone or online support group facilitated by the Cancer Council Victoria, Melbourne, Australia. Two dominant participant narratives emerged: a focus on dying with dignity or an interest in deferring discussion of death and dying to focus on the present. Despite the different approaches, participants found the technology-based support groups to be accessible and safe environments in which to discuss difficult topics in privacy. Technology-based strategies provide opportunities for health professionals to provide social and emotional care to more people by moving beyond individualised care and facilitate peer-to-peer support at the end of life, especially to those with specific needs. Such options are feasible for palliative care services to set up and acceptable to a group of clients, especially for younger clients or those socially or geographically isolated.

    The aim of this study was to evaluate the cost-effectiveness of a multifaceted implementation strategy for the prevention of hand eczema in comparison with a control group among healthcare workers. A total of 48 departments (n=1,649) were randomly allocated to the implementation strategy or the control group. Data on hand eczema and costs were collected at baseline and every 3 months. Cost-effectiveness analyses were performed using linear multilevel analyses. The probability of the implementation strategy being cost-effective gradually increased with an increasing willingness-to-pay, to 0.84 at a ceiling ratio of €590,000 per person with hand eczema prevented (societal perspective). The implementation strategy appeared to be not cost-effective in comparison with the control group (societal perspective), nor was it cost-beneficial to the employer. However, this study had some methodological problems which should be taken into account when interpreting the results.

    Early-onset Group B haemolytic streptococcus infection (EOGBS) is an important cause of neonatal morbidity and mortality in the first week of life. Primary prevention of EOGBS is possible with intra-partum antibiotic prophylaxis (IAP.) Different prevention strategies are used internationally based on identifying pregnant women at risk, either by screening for GBS colonisation and/or by identifying risk factors for EOGBS in pregnancy or labour. A theoretical cost-effectiveness study has shown that a strategy with IAP based on five risk factors (risk-based strategy) or based on a positive screening test in combination with one or more risk factors (combination strategy) was the most cost-effective approach in the Netherlands. IAP for all pregnant women with a positive culture in pregnancy (screening strategy) and treatment in line with the current Dutch guideline (IAP after establishing a positive culture in case of pre-labour rupture of membranes or preterm birth and immediate IAP in case of intra-partum fever, previous sibling with EOGBS or GBS bacteriuria), were not cost-effective. Cost-effectiveness was based on the assumption of 100% adherence to each strategy. However, adherence in daily practice will be lower and therefore have an effect on cost-effectiveness. The aims are to: a.) implement the current Dutch guideline, the risk-based strategy and the combination strategy in three pilot regions and b.) study the effects of these strategies in daily practice. Regions where all the care providers in maternity care implement the allocated strategy will be randomised. Before the introduction of the strategy, there will be a pre-test (use of the current guideline) involving 105 pregnant women per region. This will be followed by a post-test (use of the allocated strategy) involving 315 women per region. The outcome measures are: 1.) adherence to the specific prevention strategy and the determinants of adherence among care providers and pregnant women, 2.) outcomes

    Previous functional neuroimaging studies demonstrated that different neural networks underlie different types of cognitive processing by engaging participants in particular tasks, such as verbal or spatial working memory (WM) tasks. However, we report here that even when a WM task is defined as verbal or spatial, different types of memory strategies may be used to complete it, with concomitant variations in brain activity. We developed a questionnaire to characterize the type of strategy used by individual members in a group of 28 young healthy participants (18-25 years) during a spatial WM task. A cluster analysis was performed to differentiate groups. We acquired functional magnetoencephalography and structural diffusion tensor imaging measures to characterize the brain networks associated with the use of different strategies. We found two types of strategies were used during the spatial WM task, a visuospatial and a verbal strategy, and brain regions and time courses of activation differed between participants who used each. Task performance also varied by type of strategy used with verbal strategies showing an advantage. In addition, performance on neuropsychological tests (indices from Wechsler Adult Intelligence Scale-IV, Rey Complex Figure Test) correlated significantly with fractional anisotropy measures for the visuospatial strategy group in white matter tracts implicated in other WM and attention studies. We conclude that differences in memory strategy can have a pronounced effect on the locations and timing of brain activation and that these differences need further investigation as a possible confounding factor for studies using group averaging as a means for summarizing results.

    2018-06-01

    Using adolescents' narratives and survey data presented in earlier studies, we draw upon Berry's model of four acculturation strategies () to examine adolescents' narratives regarding the future orientation domains of education-and-career and marriage-and-family (Seginer, ) by three groups of nonimmigrant minority adolescents in Israel: Muslim, Druze, and ultra-Orthodox Jewish. The narratives of adolescents from the three communities studied here illustrate modified assimilation for education-and-career and separation for marriage-and-family, indicating both cultural transition and continuity. Quantitative analyses mapped domain-specific links from education-and-career and marriage-and-family to adolescents' academic achievement. © 2018 Wiley Periodicals, Inc.

    Two experiments investigated the effects of strategy knowledge and strategy training on the working memory (WM) performance in children (ages 10-11) with and without reading disabilities (RD). Experiment 1 examined the relationship between strategy knowledge (stability of strategy choices) and WM performance as a function of initial, gain (cued), and maintenance conditions. WM performance was significantly improved for both groups under cued conditions; however, the performances of children with RD were inferior to those of children without RD across all memory conditions. Measures of WM capacity rather than strategy stability or processing efficiency best predicted reading comprehension performance. Experiment 2 assessed the effects of strategy training on WM performance by randomly assigning children to strategy instruction or control conditions. Significant improvements in WM performance occurred as a function of training conditions, but the residual WM differences between the reading groups remained. Although the results showed that stable strategy choices, cued performance, and strategy instruction significantly bolstered WM performance in children with RD, their overall WM performance, however, was constrained by capacity limitations.

    As course directors, we wished to incorporate small group learning into our Evidence-based Medicine course for students to get feedback on the development of a well constructed, researchable clinical question. Scheduling of these groups was problematic. We sought to evaluate computer-mediated communication as an alternative to face-to-face small groups. Students were randomly assigned to either face-to-face small groups or asynchronous, electronic, small groups. Final examination scores were analyzed with an analysis of variance to determine if there were differences in student performance based on group type. Student survey items were analyzed using Fisher's Exact test to determine if there were differences in student attitudes based on group type. There were no significant differences found in overall student performance. Significant differences in student attitudes were found to exist with respect to: (1) participation in discussions, with face-to-face groups reporting greater participation; (2) putting more thought into comments, with electronic groups reporting more thought put into comments; and (3) difficulty relating to other students in the class, with electronic groups reporting more difficulty. We found electronic discussion groups (computer-mediated communication) to be a viable teaching/learning strategy with no adverse effects on student performance or attitudes.

    The well-being of oncologists is important to the well-being of their patients. While much is known about oncologist distress, little is known about oncologist well-being. We set out to evaluate oncologist well-being and the personal wellness promotion strategies used by oncologists. We performed a cross-sectional survey of medical oncologists in the North Central Cancer Treatment Group using a validated instrument to measure quality of life. Study-specific questions explored stressors, wellness promotion strategies and career satisfaction. Of 241 responding oncologists (response rate 61%), 121 (50%) reported high overall well-being. Being age 50 or younger (57 vs. 41%; p = 0.01), male (53 vs. 31%; p = 0.01) and working 60 h or less per week (50 vs. 33%; p = 0.005) were associated with increased overall well-being on bivariate analysis. Ratings of the importance of a number of personal wellness promotion strategies differed for oncologists with high well-being compared with those without high well-being. Developing an approach/philosophy to dealing with death and end-of-life care, using recreation/hobbies/exercise, taking a positive outlook and incorporating a philosophy of balance between personal and professional life were all rated as substantially more important wellness strategies by oncologists with high well-being (p values career satisfaction. Half of medical oncologists experience high overall well-being. Use of specific personal wellness promotion strategies appears to be associated with oncologist well-being. Further investigations of the prevalence, promotion, causes, inequities and clinical impact of physician well-being are needed. .

    Comprehensive evaluation of movement strategies during functional movement is a difficult undertaking. Because of this challenge, studied movements have been oversimplified. Furthermore, evaluating movement strategies at only a discrete time point(s) provide limited insight into how movement strategies may change or adapt in chronic ankle instability (CAI) patients. This study aimed to identify abnormal movement strategies in individuals with a history of ankle sprain injury during a sports maneuver compared with healthy controls. Sixty-six participants, consisting of 22 CAI patients, 22 ankle sprain copers, and 22 healthy controls, participated in this study. Functional profiles of lower extremity kinematics, kinetics, and EMG activation from initial contact (0% of stance) to toe-off (100% of stance) were collected and analyzed during a jump landing/cutting task using a functional data analysis approach. Compared with copers, CAI patients displayed landing positions of less plantarflexion, less inversion, more knee flexion, more hip flexion, and less hip abduction during the first 25% of stance. However, restricted dorsiflexion angle was observed in both CAI patients and copers relative to controls during the midlanding to mid-side-cutting phase when the ankle and knee reached its peak range of motion (e.g., dorsiflexion and knee flexion). Reduced EMG activation of tibialis anterior, peroneus longus, medial gastrocnemius, and gluteus medius may be due to altered kinematics that reduce muscular demands on the involved muscles. CAI patients displayed altered movement strategies, perhaps in an attempt to avoid perceived positions of risk. Although sagittal joint positions seemed to increase the external torque on the knee and hip extensors, frontal joint positions appeared to reduce the muscular demands on evertor and hip abductor muscles.

    A diverse range of concentrate allocation strategies are adopted on dairy farms. The objectives of this study were to examine the effects on cow performance [dry matter (DM) intake (DMI), milk yield and composition, body tissue changes, and fertility] of adopting 2 contrasting concentrate allocation strategies over the first 140 d of lactation. Seventy-seven Holstein-Friesian dairy cows were allocated to 1 of 2 concentrate allocation strategies at calving, namely group or individual cow. Cows on the group strategy were offered a mixed ration comprising grass silage and concentrates in a 50:50 ratio on a DM basis. Cows on the individual cow strategy were offered a basal mixed ration comprising grass silage and concentrates (the latter included in the mix to achieve a mean intake of 6kg/cow per day), which was formulated to meet the cow's energy requirements for maintenance plus 24kg of milk/cow per day. Additional concentrates were offered via an out-of-parlor feeding system, with the amount offered adjusted weekly based on each individual cow's milk yield during the previous week. In addition, all cows received a small quantity of straw in the mixed ration part of the diet (approximately 0.3kg/cow per day), plus 0.5kg of concentrate twice daily in the milking parlor. Mean concentrate intakes over the study period were similar with each of the 2 allocation strategies (11.5 and 11.7kg of DM/cow per day for group and individual cow, respectively), although the pattern of intake with each treatment differed over time. Concentrate allocation strategy had no effect on either milk yield (39.3 and 38.0kg/d for group and individual cow, respectively), milk composition, or milk constituent yield. The milk yield response curves with each treatment were largely aligned with the concentrate DMI curves. Cows on the individual cow treatment had a greater range of concentrate DMI and milk yields than those on the group treatment. With the exception of a tendency for cows on the

    Full Text Available Abstract Background Recruiting to primary care studies is complex. With the current drive to increase numbers of patients involved in primary care studies, we need to know more about successful recruitment approaches. There is limited evidence on recruitment to focus group studies, particularly when no natural grouping exists and where participants do not regularly meet. The aim of this paper is to reflect on recruitment to a focus group study comparing the methods used with existing evidence using a resource for research recruitment, PROSPeR (Planning Recruitment Options: Strategies for Primary Care. Methods The focus group formed part of modelling a complex intervention in primary care in the Resources for Effective Sleep Treatment (REST study. Despite a considered approach at the design stage, there were a number of difficulties with recruitment. The recruitment strategy and subsequent revisions are detailed. Results The researchers' modifications to recruitment, justifications and evidence from the literature in support of them are presented. Contrary evidence is used to analyse why some aspects were unsuccessful and evidence is used to suggest improvements. Recruitment to focus group studies should be considered in two distinct phases; getting potential participants to contact the researcher, and converting those contacts into attendance. The difficulty of recruitment in primary care is underemphasised in the literature especially where people do not regularly come together, typified by this case study of patients with sleep problems. Conclusion We recommend training GPs and nurses to recruit patients during consultations. Multiple recruitment methods should be employed from the outset and the need to build topic related non-financial incentives into the group meeting should be considered. Recruitment should be monitored regularly with barriers addressed iteratively as a study progresses.

    For the past 3 yr, faculty at the University of New Mexico, Department of Biochemistry and Molecular Biology have been using interactive online Problem-Based Learning (PBL) case discussions in our large-enrollment classes. We have developed an illustrative tracking method to monitor student use of problem-solving strategies to provide targeted help to groups and to individual students. This method of assessing performance has a high interrater reliability, and senior students, with training, can serve as reliable graders. We have been able to measure improvements in many students' problem-solving strategies, but, not unexpectedly, there is a population of students who consistently apply the same failing strategy when there is no faculty intervention. This new methodology provides an effective tool to direct faculty to constructively intercede in this area of student development.

    The status of seabed disposal studies and possible strategies for future development are reviewed. Background information for strategy development includes presentation of selected recommendations for future studies identified by the NEA/OECD Seabed Working Group, the Engineering Studies Task Group of the Seabed Working Group and the Subseabed Consortium. Inferences from these recommendations, and how sound scientifically based research, significant political perception and technological proof of concept may be related to strategies are considered as a prelude to strategy design. A proposed European strategy, complementary to the 1988 Subseabed Consortium strategy developed in the US, is to proceed to the technological proof of concept by emplacing one or more full-sized waste canisters containing non-radioactive, simulated heat-producing waste by a chosen deployment system. The latter could include the drilled, the penetrator or the pushed-in option. Emplaced canisters would be monitored for an extended period of time, and eventually retrieved for examination. International co-operation and co-ordination of all aspects is recommended. (author)

    Our aim was to examine predictive variables associated with the improvement in cognitive, clinical, and functional outcomes after outpatient participation in REPYFLEC strategy-based Cognitive Remediation (CR) group training. In addition, we investigated which factors might be associated with some long-lasting effects at 6 months' follow-up. Predictors of improvement after CR were studied in a sample of 29 outpatients with schizophrenia. Partial correlations were computed between targeted variables and outcomes of response to explore significant associations. Subsequently, we built linear regression models for each outcome variable and predictors of improvement. The improvement in negative symptoms at posttreatment was linked to faster performance in the Trail Making Test B. Disorganization and cognitive symptoms were related to changes in executive function at follow-up. Lower levels of positive symptoms were related to durable improvements in life skills. Levels of symptoms and cognition were associated with improvements following CR, but the pattern of resulting associations was nonspecific.

    Dominance in the peer group is important for adolescents. Resource Control Theory posits that both coercive and prosocial (positively assertive) strategies are associated with dominance. Combining Resource Control Theory with Socioanalytic Theory on personality, we hypothesized that inspiring group members would be an additional effective strategy. This study examined whether the three behavioral strategies and two types of social skills (social competence and manipulation) predicted dominance (resource control and popularity). Participants were 619 Dutch adolescents (M age  = 13.1; 47% female) in the first grade of secondary school. They completed peer reports (behavioral strategies and dominance) and self-reports (social skills). Only inspirational and coercive strategies substantially predicted dominance. Main effects of social skills emerged. Moderation between strategies and social skills was only observed for girls (e.g., coercive strategy use was associated with more popularity for girls with higher levels of social manipulation skills). This study furthered our understanding of the predictors of dominance in adolescence by including inspirational behavior and examining prosocial and antisocial skills.

    1995-09-01

    Female lions (Panthera leo) showed persistent individual differences in the extent to which they participated in group-territorial conflict. When intergroup encounters were simulated by playback of aggressive vocalizations, some individuals consistently led the approach to the recorded intruder, whereas others lagged behind and avoided the risks of fighting. The lead females recognized that certain companions were laggards but failed to punish them, which suggests that cooperation is not maintained by reciprocity. Modification of the "odds" in these encounters revealed that some females joined the group response when they were most needed, whereas other lagged even farther behind. The complexity of these responses emphasizes the great diversity of individual behavior in this species and the inadequacy of current theory to explain cooperation in large groups.

    Evolution strategies have more than 50 years of history in the field of evolutionary computation. Since the early 1990s, many algorithmic variations of evolution strategies have been developed, characterized by the fact that they use the so-called derandomization concept for strategy parameter adaptation. Most importantly, the covariance matrix adaptation strategy (CMA-ES) and its successors are the key representatives of this group of contemporary evolution strategies. This book provides an overview of the key algorithm developments between 1990 and 2012, including brief descriptions of the a

    The aim of the current study is to identify strategies to promote healthy eating in young children that can be applied by caregivers, based on their own perceptions of effectiveness and feasibility. Whereas previous research mainly focused on parental influences on children's eating behavior, the growing role of other caregivers in the upbringing of children can no longer be denied. Four focus groups were conducted with three types of caregivers of post-weaning children under 6 years old: parents (n = 14), family child care providers (n = 9), and daycare assistants (n = 10). The audiotaped focus group discussions were transcribed and imported into Nvivo 10.0 for thematic analysis. The behaviors put forward by the caregivers were categorized within three broad dimensions: global influences, general behaviors, and specific feeding practices. Perceived effective strategies to promote healthy eating behavior in children included rewards, verbal encouragement, a taste-rule, sensory sensations, involvement, variation, modeling, repeated exposure, and a peaceful atmosphere. Participants mainly disagreed on the perceived feasibility of each strategy, which largely depended on the characteristics of the caregiving setting (e.g. infrastructure, policy). Based on former research and the current results, an intervention to promote healthy eating behaviors in young children should be adapted to the caregiving setting or focus on specific feeding practices, since these involve simple behaviors that are not hindered by the limitations of the caregiving setting. Due to various misconceptions regarding health-promoting strategies, clear instructions about when and how to use these strategies are necessary.

    Providing drinking water to U.S. children during school meals is a recommended health promotion strategy and part of national nutrition policy. Urban school systems have struggled with providing drinking water to children, and little is known about how to ensure that water is served, particularly in afterschool settings. To assess the effectiveness of an intervention designed to promote water as the beverage of choice in afterschool programs. The Out of School Nutrition and Physical Activity Initiative (OSNAP) used a community-based collaboration and low-cost strategies to provide water after school. A group RCT was used to evaluate the intervention. Data were collected in 2010-2011 and analyzed in 2011. Twenty afterschool programs in Boston were randomized to intervention or control (delayed intervention). Intervention sites participated in learning collaboratives focused on policy and environmental changes to increase healthy eating, drinking, and physical activity opportunities during afterschool time (materials available at www.osnap.org). Collaboration between Boston Public Schools Food and Nutrition Services, afterschool staff, and researchers established water-delivery systems to ensure children were served water during snack time. Average ounces of water served to children per day was recorded by direct observation at each program at baseline and 6-month follow-up over 5 consecutive school days. Secondary measures directly observed included ounces of other beverages served, other snack components, and water-delivery system. Participation in the intervention was associated with an increased average volume of water served (+3.6 ounces/day; p=0.01) during snack. On average, the intervention led to a daily decrease of 60.9 kcals from beverages served during snack (p=0.03). This study indicates the OSNAP intervention, including strategies to overcome structural barriers and collaboration with key actors, can increase offerings of water during afterschool snack

    Full Text Available Background. Most instruments, including the well-known Motivated Strategies for Learning Questionnaire (MSLQ, have been designed in western homogeneous settings. Use of the MSLQ in health professions education is limited. Objective. To assess the MSLQ and its association with the academic performance of a heterogeneous group of 1st-year medical students. Methods. Eighty-three percent of 1st-year medical students consented to participate in this quantitative study. The MSLQ consisted of a motivation strategies component with six subscales, while the learning strategies component had nine subscales. Demographic and academic achievement information of the students was also collected. Stata version 13 (StataCorp LP, USA was used for the statistical analyses of all data. Results. Female students displayed significantly higher motivational scores. Students with prior educational experience and those who attended peer mentoring sessions had significantly higher learning strategy scores. Significant but moderate relationships were found between academic performance and the motivation strategies subsumed within the categories ‘task value’ and ‘self-efficacy for learning performance’. In terms of the ‘learning strategy component’, ‘critical thinking’, and ‘time and study environment’, the composite score was significantly but poorly correlated to academic performance. Conclusion. Overall, limited correlations were found between the MSLQ scores and academic performance. Further investigation of the use of the MSLQ and its association with academic achievement is recommended, with greater focus on specific learning events than on course outcomes. This study highlights the importance of evaluating an instrument in a specific context before accepting the findings of others with regard to the use of the instrument and its correlation with academic performance.

    Full Text Available Purpose: This study compared the effectiveness of group cognitive-behavioral therapy based on coping skills (CBT and methadone maintenance therapy (MMT in improvement of emotional regulation strategies and prevention of relapse. Method: The method of the present study was semi-experimental research design (pre-test-post-test with witness group. For sampling 45 substance abuse people who had referred to addiction treatment centers were selected and assigned to three groups of cognitive behavior therapy, methadone maintenance treatment and witness group randomly. The participants in all three groups completed the emotional intelligence questionnaire before and after the intervention. Data were analyzed by covariance method. Results: The results showed that cognitive-behavior therapy in comparison to methadone maintenance therapy and witness group led to significant improvement of emotional regulation in substance abusers, but there was no significant difference between the methadone maintenance treatment group and control group. Also, the rate of relapse in individuals who assigned to cognitive-behavior therapy group in comparison to methadone maintenance therapy and the witness group was significantly lower, but there was no significant difference between methadone therapy and witness. Conclusion: Cognitive-behavior therapy was an effective treatment that can change the cognitive and behavioral variables related to substance abuse, such as emotional regulation strategies. Thus, results suggested that drug abuse treatment programs must target these mediator variables.

    Occupational sitting can be the largest contributor to overall daily sitting time in white-collar workers. With adverse health effects in adults, intervention strategies to influence sedentary time on a working day are needed. Therefore, the present aim was to examine employees' and executives' reflections on occupational sitting and to examine the potential acceptability and feasibility of intervention strategies to reduce and interrupt sedentary time on a working day. Seven focus groups (four among employees, n = 34; three among executives, n = 21) were conducted in a convenience sample of three different companies in Flanders (Belgium), using a semi-structured questioning route in five themes [personal sitting patterns; intervention strategies during working hours, (lunch) breaks, commuting; and intervention approach]. The audiotaped interviews were verbatim transcribed, followed by a qualitative inductive content analysis in NVivo 10. The majority of participants recognized they spend their working day mostly sitting and associated this mainly with musculoskeletal health problems. Participants suggested a variety of possible strategies, primarily for working hours (standing during phone calls/meetings, PC reminders, increasing bathroom use by drinking more water, active sitting furniture, standing desks, rearranging the office) and (lunch) breaks (physical activity, movement breaks, standing tables). However, several barriers were reported, including productivity concerns, impracticality, awkwardness of standing, and the habitual nature of sitting. Facilitating factors were raising awareness, providing alternatives for simply standing, making some strategies obligatory and workers taking some personal responsibility. There are some strategies targeting sedentary time on a working day that are perceived to be realistic and useful. However several barriers emerged, which future trials and practical initiatives should take into account.

    Applied optics course in Zhejiang University is a National Excellent Resource Sharing Course in China, and the online to offline teaching strategies have been implemented and shared with dozens of universities and colleges in China. Discussion is an important activity in teaching. In this paper our main consideration is designing the discussion questions and group works so as to develop the students' critical thinking, cooperative and sharing spirits, and communication abilities in the cosmopolitan era. Typical questions that connect different chapters and help the students to understand the relationship between each sub-system in both field of view and aperture are given for discussion. We inspire the students to complete group works such as ray trace programming by cooperation and then make presentations. All of these create a circumstance for sharing thoughts and developing intelligence and knowledge. A poll shows that the students pay more attention to optical design than before and have made progress in conversation and cooperation.

  7. Social Defense: An Evolutionary-Developmental Model of Children's Strategies for Coping with Threat in the Peer Group

    Full Text Available Navigating the ubiquitous conflict, competition, and complex group dynamics of the peer group is a pivotal developmental task of childhood. Difficulty negotiating these challenges represents a substantial source of risk for psychopathology. Evolutionary developmental psychology offers a unique perspective with the potential to reorganize the way we think about the role of peer relationships in shaping how children cope with the everyday challenges of establishing a social niche. To address this gap, we utilize the ethological reformulation of the emotional security theory as a guide to developing an evolutionary framework for advancing an understanding of the defense strategies children use to manage antagonistic peer relationships and protect themselves from interpersonal threat (Davies and Sturge-Apple, 2007. In this way, we hope to illustrate the value of an evolutionary developmental lens in generating unique theoretical insight and novel research directions into the role of peer relationships in the development of psychopathology.

    Ethnic minorities living in high-income countries usually exhibit a greater risk of developing diabetes along with higher morbidity and mortality rates. We evaluated the effectiveness of interventions to improve glycaemic control in ethnic minority groups. Results of major controlled trials, systematic reviews and meta-analyses were included in the review. Only 1/47 studies addressing diet and exercise interventions reported details on the ethnicity of the studied population. Self-management education was successful if associated with increased self-efficacy; delivered over a longer period; of high intensity; culturally tailored; and when using community educators. Strategies adopted in community-gathering places, family-based, multifaceted, and those tackling the social context were likely to be more effective. A positive relationship was found between social support and self-management behaviour as well as quality of life, but there is little evidence about the impact of organizational changes within health-care services on diabetes control. More research is needed to strengthen the evidence on effective strategies for response to diabetes in ethnic minorities. Also, there is a need to take into account diabetes beliefs and communication difficulties, as well as potential protective factors. Globally, many health-care systems are inadequately equipped to improve diabetes prevention and disease outcomes in these communities. 2010 John Wiley & Sons, Ltd.

    Applying the framework of ecological rationality, the authors studied the adaptivity of group decision making. In detail, they investigated whether groups apply decision strategies conditional on their composition in terms of task-relevant features. The authors focused on the recognition heuristic, so the task-relevant features were the validity of the group members' recognition and knowledge, which influenced the potential performance of group strategies. Forty-three three-member groups performed an inference task in which they had to infer which of two German companies had the higher market capitalization. Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance. Time constraints had no effect on strategy use but did have an effect on the proportions of different types of arguments. Possible mechanisms underlying the adaptive use of recognition in group decision making are discussed. © 2014 Cognitive Science Society, Inc.

  15. Emerging Competitive Strategies in the Global Luxury Industry in the Perspective of Sustainable Development: the Case of Kering Group

    Roberta PEZZETTI

    2016-06-01

    Full Text Available In the last years, many drivers should motivate luxury companies to engage in more sustainable practices. On the one hand, consumers seek new forms of luxury that shows respect for natural resources and human beings, yet standing by traditional factors such as quality, creativity, originality, craftsmanship and savoirfaire. The recent economic crisis has thrust the consumers towards the search for responsible luxury. In the new economic and competitive scenario, luxury brands would base their identity and image on a set of values through which they should be known and publicly judged by both clients and the market; sustainable development and corporate social responsibility strategies offer a particularly suitable platform to enrich the value-set of luxury brands. In this framework, the luxury industry is undergoing a process of self-analysis and redefinition of competitive strategies in the light of social responsibility and sustainable dimension. In order to create both financial and non-financial value, sustainable development needs to be incorporated in the core strategy of the firm and its core business. In this perspective, the paper provides an analysis of the main drivers that, in the luxury industry, are leading to a growing integration of social responsibility and sustainable development principles in the competitive strategies of luxury firms. In particular, the paper focuses on innovations emerging in the luxury industry, both at strategic and organizational levels, and provides an overview of new emerging innovative business models coherent with the principles of corporate social responsibility and sustainability. The theoretical analysis is supported by presentation of the case of the French Group Kering, which represents a pioneering example in sustainable development applied to competitive strategies and leading brand management practices.

    2016-07-01

    This study aimed to determine whether the recall of gestures in working memory could be enhanced by verbal or gestural strategies. We also attempted to examine whether these strategies could help resist verbal or gestural interference. Fifty-four participants were divided into three groups according to the content of the training session. This included a control group, a verbal strategy group (where gestures were associated with labels) and a gestural strategy group (where participants repeated gestures and were told to imagine reproducing the movements). During the experiment, the participants had to reproduce a series of gestures under three conditions: "no interference", gestural interference (gestural suppression) and verbal interference (articulatory suppression). The results showed that task performance was enhanced in the verbal strategy group, but there was no significant difference between the gestural strategy and control groups. Moreover, compared to the "no interference" condition, performance decreased in the presence of gestural interference, except within the verbal strategy group. Finally, verbal interference hindered performance in all groups. The discussion focuses on the use of labels to recall gestures and differentiates the induced strategies from self-initiated strategies.

    Centering Pregnancy, an innovative group model of prenatal care, shows promise to reduce persistent adverse maternal-infant outcomes and contain costs. Because this innovation requires systemwide change, clinics reported needing support enrolling women into groups and obtaining organizational buy-in. This study used the 3-step social marketing communication strategy to help clinic staff identify key customers and customer-specific barriers to adopting or supporting Centering Pregnancy. They developed targeted information to reduce barriers and built skills in communicating with different customers through role-playing. Findings provide practical information for others to use this communication strategy to improve implementation of Centering Pregnancy.

    In this study we made an effort to identify the kinds of strategies adolescents deploy in achievement context in an unselected sample of Swedish adolescents. The participants were 880 14-15-year-old comprehensive school students (399 boys and 481 girls) from a middle-sized town in central Sweden. Six groups of adolescents were identified according to the strategies they deployed. Four of them, i.e. optimistic, defensive pessimistic, self-handicapping and learned helplessness strategies, were similar to those described previously in the literature. The results showed that membership in the functional strategy groups, such as in mastery-oriented and defensive pessimist groups, was associated with well-being, school adjustment and achievement, and low levels of norm-breaking behaviour. By contrast, membership in the dysfunctional, for example self-handicapping and learned helplessness strategy groups, was associated with low levels of well-being, and of school adjustment, and a higher level of norm-breaking behaviour.

    2016-12-01

    Full Text Available Background: Despite undeniable evidence for the efficacy and effectiveness of Cognitive Behaviour Therapy for Insomnia (CBT-I, the potential for its widespread dissemination and implementation has yet to be realised. A suggested reason for this is that traditional CBT-I is considered too burdensome for deployment, in its current form, within the context of where it would be most beneficial—Primary Care. One strategy, aimed to address this, has been to develop briefer versions of CBT-I, whilst another has been to deliver CBT-I in a group format. An alternative has been to attempt to address insomnia during its acute phase with a view to circumventing its progression to chronic insomnia. The aim of the present study was to compare a brief version of CBT-I (one-shot when delivered individually or in groups to those with acute insomnia. Method: Twenty-eight individuals with acute insomnia (i.e., meeting full DSM-5 criteria for insomnia disorder for less than three months self-assigned to either a group or individual treatment arm. Treatment consisted of a single one-hour session accompanied by a self-help pamphlet. Subjects completed measures of insomnia severity, anxiety and depression pre-treatment and at one-month post-treatment. Additionally, daily sleep diaries were compared between pre-treatment and at the one-month follow up. Results: There were no significant between group differences in treatment outcome on any sleep or mood measures although those in the group treatment arm were less adherent than those who received individual treatment. Furthermore, the combined (group and individual treatment arms pre-post test effect size on insomnia symptoms, using the Insomnia Severity Index, was large (d = 2.27. Discussion: It appears that group treatment is as efficacious as individual treatment within the context of a “one shot” intervention for individuals with acute insomnia. The results are discussed with a view to integrating one-shot CBT

    This study investigated whether secondary school students who were taught a motor learning strategy could transfer their knowledge of the strategy to learning a novel task. Twenty adolescents were randomly allocated to a strategy or control group. The strategy group was taught Singer's five-step learning strategy, while the control group received information on the evolution and biomechanics of the basketball free throw. Both groups received three 1-hour practice sessions on a modified basketball shooting task. After one month, participants were introduced to the transfer task, golf putting. Performance accuracy was recorded for all tasks, and participants completed questionnaires regarding strategy use during practice. Participants taught the five-step learning strategy successfully recalled and applied it after a 1-month interval, and they demonstrated superior performance on both acquisition and transfer tasks, relative to the control group. Physical education teachers and coaches should consider using this learning strategy to enhance the learning of closed motor skills.

    In view of the slow progress being made in reducing maternal and child mortality in many priority countries, new approaches are urgently needed that can be applied in settings with weak health systems and a scarcity of human resources for health. The Care Group approach uses facilitators, who are a lower-level cadre of paid workers, to work with groups of 12 or so volunteers (the Care Group), and each volunteer is responsible for 10-15 households. The volunteers share messages with the mothers of the households to promote important health behaviors and to use key health services. The Care Groups create a multiplying effect, reaching all households in a community at low cost. This article describes the Care Group approach in more detail, its history, and current NGO experience with implementing the approach across more than 28 countries. A companion article also published in this journal summarizes the evidence on the effectiveness of the Care Group approach. An estimated 1.3 million households—almost entirely in rural areas—have been reached using Care Groups, and at least 106,000 volunteers have been trained. The NGOs with experience implementing Care Groups have achieved high population coverage of key health interventions proven to reduce maternal and child deaths. Some of the essential criteria in applying the Care Group approach include: peer-to-peer health promotion (between mothers), selection of volunteers by mothers, limited workload for the volunteers, limited number of volunteers per Care Group, frequent contact between the volunteers and mothers, use of visual teaching tools and participatory behavior change methods, and regular supervision of volunteers. Incorporating Care Groups into ministries of health would help sustain the approach, which would require creating posts for facilitators as well as supervisors. Although not widely known about outside the NGO child survival and food security networks, the Care Group approach deserves broader

    Altered postural control and balance are major disabling issues of Parkinson's disease (PD). Static and dynamic posturography have provided insight into PD's postural deficits; however, little is known about impairments in postural coordination. We hypothesized that subjects with PD would show more ankle strategy during quiet stance than healthy control subjects, who would include some hip strategy, and this stiffer postural strategy would increase with disease progression. We quantified postural strategy and sway dispersion with inertial sensors (one placed on the shank and one on the posterior trunk at L5 level) while subjects were standing still with their eyes open. A total of 70 subjects with PD, including a mild group (H&Y≤2, N=33) and a more severe group (H&Y≥3, N=37), were assessed while OFF and while ON levodopa medication. We also included a healthy control group (N=21). Results showed an overall preference of ankle strategy in all groups while maintaining balance. Postural strategy was significantly lower ON compared to OFF medication (indicating more hip strategy), but no effect of disease stage was found. Instead, sway dispersion was significantly larger in ON compared to OFF medication, and significantly larger in the more severe PD group compared to the mild. In addition, increased hip strategy during stance was associated with poorer self-perception of balance. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Investigating the efficiencies and deficiencies of reading strategies is one of the noticeable issues in the related theory and research in reading comprehension instruction. This study was to examine the impact of Directed Reading Thinking Activity (DRTA and Guided Reading (GR on reading comprehension. Sixty three Iranian students of grade one in Shahed high school in the city of Bojnourd took part in the study. They were assigned in three groups, one control and two experimental groups. The instruction lasted for ten weeks. This study utilized a pretest posttest control group in quantitative quasi- experimental design. The same reading comprehension test was administered as pre-test and post-test. The results were twofold: First, the instruction of learning strategies could foster reading comprehension skill. Second, while the explicit instruction of both strategies could improve the students' reading comprehension skill, Directed Reading Thinking Activity had a more significant positive effect than Guided Reading.

    2017-03-01

    General strategic bidding procedure has been formulated in the literature as a bi-level searching problem, in which the offer curve tends to minimise the market clearing function and to maximise the profit. Computationally, this is complex and hence, the researchers have adopted Karush-Kuhn-Tucker (KKT) optimality conditions to transform the model into a single-level maximisation problem. However, the profit maximisation problem with KKT optimality conditions poses great challenge to the classical optimisation algorithms. The problem has become more complex after the inclusion of transmission constraints. This paper simplifies the profit maximisation problem as a minimisation function, in which the transmission constraints, the operating limits and the ISO market clearing functions are considered with no KKT optimality conditions. The derived function is solved using group search optimiser (GSO), a robust population-based optimisation algorithm. Experimental investigation is carried out on IEEE 14 as well as IEEE 30 bus systems and the performance is compared against differential evolution-based strategic bidding, genetic algorithm-based strategic bidding and particle swarm optimisation-based strategic bidding methods. The simulation results demonstrate that the obtained profit maximisation through GSO-based bidding strategies is higher than the other three methods.

    Psychosocial consequences of traumatic spinal cord injury (SCI) have been well documented in Western populations, but there is no published literature on such incidence in the Sri Lankan population. The purpose of this study was to explore the psychosocial impact of SCI in a Sri Lankan population and to examine this population's coping mechanisms. Participants were recruited purposively at the Ragama Rheumatology and Rehabilitation Hospital, the sole rehabilitation facility for SCI patients in Sri Lanka. Focus groups were conducted with 23 consenting individuals. Interview transcripts were analysed using descriptive thematic analysis. Four domains of life impact, three types of active coping strategies and four types of external supports were identified. Decreased ambulation and burden on family life were significant concerns for male and female participants alike. Religious practices were reported most frequently as active coping strategies, followed by positive reframing and goal-setting. Reported external supports included guided physiotherapy, informational workshops, social support and peer networks. Rehabilitation efforts for Sri Lankan SCI patients should be sensitive to psychosocial concerns in addition to physical concerns in order to help patients re-integrate into their family lives and community. Furthermore, religious practices should be respected as possible aids to rehabilitation. Implications for Rehabilitation Rehabilitative efforts should be conscientious of patients' psychosocial well-being in addition to their physical well-being. Hospital-based rehabilitative efforts for traumatic spinal cord injury patients should promote functional independence and community re-integration. Spiritual and/or religious practices should be respected as ways by which traumatic spinal cord injury patients may confront personal challenges that arise following injury.

  3. Improving Reading Comprehension Skills through Reading Strategies Used by a Group of Foreign Language Learners

    Directory of Open Access Journals (Sweden)

    Nancy Gómez Torres

    2009-12-01

    Full Text Available A research study included the examination and implementation of a variety of strategies in order to improve students’ reading comprehension skills in a foreign language. Reading is the process of identification, interpretation and perception of written or printed material. Comprehension is the understanding of the meaning of written material and involves the conscious strategies that lead to understanding. The reading strategies are conscious techniques or unconscious processes employed by readers in their attempt to make sense of the written text (Barnett as cited by Gascoigne, 2005. Thus, the main goal of this piece of research was to implement some reading strategies in 2 elementary courses in EFL in order to obtain better results in the middle and long term in class and on ECAES, MICHIGAN, MELICET and PET tests.

    Full Text Available This paper is a quasi-experimental research. It was aimed to investigate the significant difference on vocabulary achievement between two groups who were taught by using Mind Mapping strategy and those who were taught by using Making Notes strategy. The subjects of this study were the students in class 5B and 5D of An-Nissa Islamic Billingual Elementary School of Semarang. 5B was the experimental group and 5D was the control group. In this research, I gave them a pre-test, treatments, and a post-test. I used the same instrument in the pre-test for both groups. They were asked to answer some questions of vocabulary test. The treatments were given in three meetings. The treatment used in the experimental group was Mind Mapping strategy, while the treatment in the control group was Making Notes strategy. The post-test in both groups were conducted after the treatments by using the same instrument as the pre-test but the position of question numbers were reshuffled. The result of the test was analyzed by using t-test formula to know the difference of the students‘ achievement in vocabulary between two groups. The analysis of the test result showed that the experimental group got better score than the control group. That calculation revealed that the hypothesis 1 (Ha was accepted and the hypothesis 2 (Ho was rejected. Based on the proven hypotheses, I concluded that Mind Mapping strategy is more effective to be implemented in teaching vocabulary than Making Notes strategy.

    1995-05-01

    The Biogas and Landfill Gas Marketing Strategy Group was set up with the objective to advise EU-DG 17 (THERMIE/OPET) on the dissemination strategies for biogas and landfill gas (LFG), a subsector of the Renewable Energy Sector (RES). The Marketing Strategy Group has identified market barriers and users' needs in the biogas and LFG subsector. Subsequently, the group evaluated successful instruments/methods to overcome these market barriers and to satisfy the users' needs. The group investigated the feasibility of transposing these instruments/success stories to other countries. The work of the Marketing Strategy Group resulted in proposals for future dissemination of biogas and LFG technology. After a short introduction into LFG technology and the LFG market, this document describes barriers to landfill gas technology dissemination and gives some examples about how to overcome them. This results in recommendations on a strategy for dissemination of LFG technology and expanding LFG markets. The document is mainly based on experience gained in the United Kingdom, Italy and the Netherlands

    A test-intervention-test study was conducted investigating the role of intelligence on four parameters of strategy competence in the context of a numerosity judgment task. Moreover, the effectiveness of two feedback types on these four parameters was tested. In the two test sessions, the choice/no-choice method was used to assess the strategy repertoire, frequency, efficiency, and adaptivity of a group of low-, average-, and high-intelligence children. During the intervention, half of the participants from each intelligence group were given outcome feedback (OFB), whereas the other half received strategy feedback (SFB). The pretest data showed large differences among the three intelligence groups on all four strategy parameters. These differences had disappeared at the posttest due to a particularly strong improvement on all strategy parameters in the low-intelligence group. Furthermore, it was found that SFB was more beneficial than OFB for all parameters involving strategy selection. These results indicate that intelligence plays an important role in children's strategy use and suggest that strategy feedback can be a powerful instructional tool, especially for low-intelligence children.

    In the present study, we assess the effects of the Expect Respect Support Groups (ERSG) on frequency of teen dating violence (TDV) and general youth violence. ERSG is a school-based violence prevention program for youth who have been exposed to violence in their home, school, or community. Boys and girls (N=1,678, M age =14.3, S.D.=1.7, Range=11-17) from 36 schools in Texas participated in this accelerated longitudinal (7-year trajectory) study beginning in 2011. Latent growth curve analyses were conducted using three waves of data from three cross-sectional cohorts of adolescents. Among boys, the number of ERSG sessions attended related to incremental declines in psychological TDV perpetration and victimization, physical TDV victimization, sexual TDV perpetration and victimization, reactive aggression, and proactive aggression. Girls attending ERSG demonstrated reductions in reactive and proactive aggression. The present findings suggest ERSG may be an effective cross-cutting strategy to reduce TDV and other forms of violence among high-risk boys and possibly girls. This information provides valuable understanding of TDV and youth violence in high-risk populations and may be useful in tailoring future prevention efforts to different groups of teens.

    As mnemonic utilization deficit in older adults associates with age-related decline in executive function, we hypothesized that memory strategy training combined with executive function training might induce larger training effect in memory and broader training effects in non-memory outcomes than pure memory training. The present study compared the effects of combined cognitive training (executive function training plus memory strategy training) to pure memory strategy training. Forty healthy older adults were randomly assigned to a combined cognitive training group or a memory strategy training group. A control group receiving no training was also included. Combined cognitive training group received 16 sessions of training (eight sessions of executive function training followed by eight sessions of memory strategy training). Memory training group received 16 sessions of memory strategy training. The results partly supported our hypothesis in that indeed improved performance on executive function was only found in combined training group, whereas memory performance increased less in combined training compared to memory strategy group. Results suggest that combined cognitive training may be less efficient than pure memory training in memory outcomes, though the influences from insufficient training time and less closeness between trained executive function and working memory could not be excluded; however it has broader training effects in non-memory outcomes.

    As the number of patients with complex healthcare needs grows, inter-professional collaboration between primary care professionals must be constantly optimized. General practitioners (GPs) and community nurses (CNs) are key professions in primary care; however, poor GP-CN communication is common, and research into the factors influencing its quality is limited. To explore patient-related GP-CN communication and facilitating and hindering factors, and to identify strategies to enhance this communication. A qualitative focus group design was used to identify the facilitating and hindering factors and strategies for improvement. In a Dutch primary care setting, 6 mono-professional focus group interviews (3 meetings of 13 GPs; 3 meetings of 18 CNs) were organized between June 2015 and April 2016, recorded and transcribed verbatim. Two independent researchers performed the coding of these interviews, identifying their categories and themes. Results show that, despite the regular contact between GPs and CNs, communication was generally perceived as poor in effectiveness and efficiency by both professions. Mutual trust was considered the most important facilitating factor for effective communication. Profession-specific factors (e.g. differences in responsibility and profession-specific language) and organizational factors (e.g. lack of shared care plans, no in-person communication, lack of time) may be of influence on communication. Participants' suggestions for improvement included organizing well-structured and reimbursed team meetings and facilitating face-to-face contact. GP-CN patient-related communication benefits most from trusting inter-personal relationships. Inter-professional training programmes should address both professional and organizational factors and should be evaluated for their effect on quality of care.

    College students' use of protective behavioral strategies (PBS; e.g., determining not to exceed a set number of drinks, avoiding drinking games) is related to lower levels of alcohol consumption and problems. The present study evaluated the efficacy of a novel brief, single-session group PBS skills training intervention aimed at increasing college students' use of PBS and reducing risky drinking and consequences. Participants (N = 226) were heavy-drinking incoming first-year college women randomized to either a PBS skills training intervention or study skills control condition. Participants attended a 45-min group session and completed online surveys pre- and postintervention (1 month and 6 months). We conducted a series of 2 × 2 × 3 repeated-measures ANCOVAs with condition and baseline mental health (anxiety/depression) as the between-subjects factors and time as the within-subjects factor. Intervention participants, relative to controls, reported significantly greater increases in PBS use and reductions in both heavy episodic drinking and alcohol consequences. The intervention was particularly effective in increasing PBS use at 1 month among participants with high anxiety. Further, tests of moderated mediation showed a significant conditional indirect effect of condition on 1-month consequences through PBS use among participants with high levels of anxiety. Findings provide preliminary support for a brief PBS-specific group intervention to reduce alcohol risk among college women, particularly anxious women. Future research is needed to strengthen the long-term effectiveness of the present approach and further explore the moderating effects of mental health.

    Full Text Available The present study investigated the extent to which an instructional framework of integrating strategy instruction (open-ended strategy and fill-in-the blanks strategy with motivation- support affected on reading result for young EFL learners. The central area of exploration included a comparison among three approaches to reading instruction: First, fill-in-the blanks strategy intervention; second, open-ended strategy intervention; and last, a control group which received the conventional reading strategies. The participants were sampled from amongst a group of seventy-seven pre-intermediate EFL learners in a language school in Tehran- Iran based on convenient sampling technique. For the sake of measurement, the researchers administered PET and CELT along with reading strategy based-test to quantify the participants’ current level of knowledge as well as the degree of achievement after treatment. For measurement’s sake, different types of tests such as PET, reading comprehension test (CELT, and reading strategy based- test were employed to quantify the participants’ current level of knowledge as well as the degree of achievement before and after instruction. The result of the present study indicated that the experimental groups had a significant improvement over the control group. Also, the level of learners’ reading engagement during classroom work mediated the instructional effects on reading outcomes. The results of this study can be to the benefit of both EFL and ESL teachers to teach reading comprehension using the student's critical mind as well as critical involvement in the reading tasks.

  17. Automated Reasoning Across Tactical Stories to Derive Lessons Learned

    Directory of Open Access Journals (Sweden)

    J. Wesley Regian

    2008-06-01

    Full Text Available The Military Analogical Reasoning System (MARS is a performance support system and decision aid for commanders in Tactical Operations Centers. MARS enhances and supports the innate human ability for using stories to reason about tactical goals, plans, situations, and outcomes. The system operates by comparing many instances of stored tactical stories, determining which have analogous situations and lessons learned, and then returning a description of the lessons learned. The description of the lessons learned is at a level of abstraction that can be generalized to an appropriate range of tactical situations. The machine-understandable story representation is based on a military operations data model and associated tactical situation ontology. Thus each story can be thought of, and reasoned about, as an instance of an unfolding tactical situation. The analogical reasoning algorithm is based on Gentner's Structure Mapping Theory. Consider the following two stories. In the first, a U.S. platoon in Viet Nam diverts around a minefield and subsequently comes under ambush from a large hill overlooking their new position. In the second, a U.S. task force in Iraq diverts around a biochemical hazard and subsequently comes under ambush from the roof of an abandoned building. MARS recognizes these stories as analogical, and derives the following abstraction: When enemy-placed obstacles force us into an unplanned route, beware of ambush from elevation or concealment. In this paper we describe the MARS interface, military operations data model, tactical situation ontology, and analogical reasoning algorithm.

  18. POSITIONING STRATEGIES DEVELOPMENT

    2014-07-01

    Full Text Available The positioning strategy has suffered serious changes in the last few decades, being influenced by the rapid development of competition and the growing focus on specific traits belonging to the market, to the consumer or to the product. The purpose of this paper is to present the developments of theoretical positioning strategies and the orientation from more simple, product oriented strategies, to ones more oriented towards the client and with a briefer period of time. The world is moving in a much faster pace than in the past, thanks to communication development so companies are obliged to adopt more specific strategies in order for them to be effective. This essay represents a literary review presenting a documentary research within the scientific articles and strategy and positioning books. The paper begins with the analysis of company strategies and the marketing strategies in general. The first author to group the product positioning strategies is Porter with his three generic strategies. Following the development of brands and because of the lack of competitiveness in the simple generic positioning strategies, this paper has also presented the newer positioning strategies proposed by Kotler, Treacy & Wiersema, and also more complex ones such as Bowman's Strategy Clock and Blankson and Kalafatis positioning strategy based on the type of the consumer. The fast expansion of local brands in all categories has led to mistakes in positioning strategies, categories also presented in the current essay. The results of this study show that new positioning strategies are more and more based on the consumer and market segments and on the product specification - which have also evolved in the last decades. Adaptability to fast changes in the competitive market will represent the future positioning strategies.

    Turbulence may enhance contact rates between planktonic predators and their prey. We formulate simple and general models of prey encounter rates, taking into account the behaviours and motility patterns of both prey and predator as well as turbulent fluid motion. Using these models we determine...... the levels of turbulence (as dissipation rate) at which ambient fluid motion is important in enhancing prey encounter rates for various types of predators (e.g, ambush and cruise predators, suspension feeders). Generally, turbulence has the largest effect on prey encounters for predators with low motility...... and long reaction distances. Also, turbulence is most important for meso-sized (mm to cm) predators and insignificant for smaller and larger predators. The effect of turbulence on copepods is specifically examined. For copepods that establish feeding currents, turbulence is of minor importance; for ambush...

Recent folksonomy systems explore the use of tag assignments, which combine Web resources with annotations (tags), and the users that have created the annotations. This article investigates on the effect of grouping resources in folksonomies, i.e. creating sets of resources, and using this additional structure for the tasks of search & ranking, and for tag recommendations. We propose several group-sensitive extensions of graph-based search and recommendation algorithms, and compare them with non group-sensitive versions. Our experiments show that the quality of search result ranking can be significantly improved by introducing and exploiting the grouping of resources (one-tailed t-Test, level of significance α=0.05). Furthermore, tag recommendations profit from the group context, and it is possible to make very good recommendations even for untagged resources- which currently known tag recommendation algorithms cannot fulfill.

  4. Security force-adversary engagement simulation

    Bennett, H.A.

    1975-01-01

    A dynamic simulation of a security force-adversary engagement has been developed to obtain a better understanding of the complexities involved in security systems. Factors affecting engagement outcomes were identified and interrelated to represent an ambush of an escorted nuclear fuel truck convoy by an adversary group. Other forms of engagement such as assault and skirmish also can be simulated through suitable parameter changes. The dynamic model can provide a relative evaluation of changes in security force levels, equipment, training, and tactics. Continued application and subsequent refinements of the model are expected to augment the understanding of component interaction within a guard-based security system

  5. Prey switching behaviour in the planktonic copepod Acartia tonsa

    DEFF Research Database (Denmark)

    Kiørboe, Thomas; Saiz, E.; Viitasalo, M.

    1996-01-01

    The copepod Acartia tonsa has 2 different prey encounter strategies. It can generate a feeding current to encounter and capture immobile prey (suspension feeding) or it can sink slowly and perceive motile prey by means of mechanoreceptors on the antennae (ambush feeding). We hypothesized that A....... tonsa adopts the feeding mode that generates the highest energy intake rate; i.e. that prey selection changes according to the relative concentrations of alternative prey (prey switching) and that the copepods spend disproportionately more time in the feeding mode that provides the greatest reward...... be captured by suspension feeding copepods. Finally, we demonstrate that turbulence favours the selection of ciliates as prey. We suggest that prey switching by copepods may provide survival windows for microzooplankters during blooms of net phytoplankton because predation pressure from the copepods...

Four intact ESL classes were divided into one control group and three treatment groups (keyword, semantic, and keyword-semantic. These Afrikaans-speaking standard 6 pupils then received 4 days of instruction. Both multiplechoice and cued-recall instruments were used to measure effects both 1 day and 9 days after instruction. The results indicated that for both the multiple-choice and cued-recall tests the combined keyword-semantic strategy differed statistically Significantly as well as practically significantly from the keyword method. The results, therefore, suggest that the combined keyword-semantic strategy increased retention above the other strategies. Hierdie artikel vergelyk die effektiwiteit van drie taalleerstrategiee (geheue strategiee vir die aanleer van woordeskat met mekaar. Vier intak Engels tweedetaal klasse is verdeel in een kontrole groep en drie eksperimentele groepe (sleutelwoord, semantiese en 'n kombinasie van die sleutelwoord-semantiese strategiee. 'n Groep Afrikaanssprekende standerd ses leerlinge het vir 'n tydperk van vier dae onderrig in elk van bogenoemde strategiee ontvang. Multikeuse en "cued-recall" instrumente is gebruik om die effek van onderrig beide een dag en nege dae na eksperimentering te bepaal. Die resultate het aangetoon dat die gekombineerde sleutelwoord-semantiese strategie statisties betekenisvol sowel as prakties betekenisvol van die sleutelwoord strategie en die kontrole groep verskil het.

    Learning from feedback is an important aspect of executive functioning that shows profound improvements during childhood and adolescence. This is accompanied by neural changes in the feedback-learning network, which includes pre-supplementary motor area (pre- SMA)/anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), superior parietal cortex (SPC), and the basal ganglia. However, there can be considerable differences within age ranges in performance that are ascribed to differences in strategy use. This is problematic for traditional approaches of analyzing developmental data, in which age groups are assumed to be homogenous in strategy use. In this study, we used latent variable models to investigate if underlying strategy groups could be detected for a feedback-learning task and whether there were differences in neural activation patterns between strategies. In a sample of 268 participants between ages 8 to 25 years, we observed four underlying strategy groups, which were cut across age groups and varied in the optimality of executive functioning. These strategy groups also differed in neural activity during learning; especially the most optimal performing group showed more activity in DLPFC, SPC and pre-SMA/ACC compared to the other groups. However, age differences remained an important contributor to neural activation, even when correcting for strategy. These findings contribute to the debate of age versus performance predictors of neural development, and highlight the importance of studying individual differences in strategy use when studying development.

    Complex systems arising in a modern society typically have many resources and strategies available for their dynamical evolutions. To explore quantitatively the behaviors of such systems, we propose a class of models to investigate Minority Game (MG) dynamics with multiple strategies. In particular, agents tend to choose the least used strategies based on available local information. A striking finding is the emergence of grouping states defined in terms of distinct strategies. We develop an analytic theory based on the mean-field framework to understand the ``bifurcations'' of the grouping states. The grouping phenomenon has also been identified in the Shanghai Stock-Market system, and we discuss its prevalence in other real-world systems. Our work demonstrates that complex systems obeying the MG rules can spontaneously self-organize themselves into certain divided states, and our model represents a basic and general mathematical framework to address this kind of phenomena in social, economical and political systems.

  19. Evolution of generous cooperative norms by cultural group selection.

    Scheuring, István

    2009-04-07

    Evolution of cooperative norms is studied in a population where individual- and group-level selection are both in operation. Individuals play indirect reciprocity game within their group. Individuals are well informed about the previous actions and reputations, and follow second-order norms. Individuals are norm-followers, and imitate their successful group mates. In contrast to previous models where norms classify actions deterministically, we assume that norms determine only the probabilities of actions, and mutants can differ in these probabilities. The central question is how a selective cooperative norm can emerge in a population where initially only non-cooperative norms were present. It is shown that evolution leads to a cooperative state if generous cooperative strategies are dominant, although the "always defecting" and the "always cooperating"-like strategies remain stably present. The characteristics of these generous cooperative strategies and the presence of always defecting and always cooperating strategies are in concordance with experimental observations.

    Full Text Available Interlanguage speakers, regardless of proficiency level, often experience problems in communication due to their limited knowledge of how speech acts are commonly performed in the target language. The current study attempted to investigate the effects of English proficiency level on the apology strategy use by Indonesian EFL (English as a Foreign Language learners from two English proficiency levels. The study employed a DCT (Discourse Completion Task questionnaire and involved 21 A2 students and 21 B1 students majoring in English in their first-year period from an Indonesian university. Utilizing the apology strategy framework from Olshtain & Cohen (1983 and Blum-Kulka, House & Kasper (1989, the findings demonstrated no significant difference between the two subject groups in the overall use of apology strategies, whereas differences were noted at an individual strategy level. Nonetheless, the B1 group made more frequent use and a wider range of apology strategies than the A2 group. In addition, the study found two forms of pragmatic transfer made by the subjects and a new apology strategy.

    Full Text Available Recognizing our own learning strategies is an effective way to help ourselves to self evaluate for what we have done in our own learning. One among other factors leading to a successful learning is due to the effective learning strategies. However, not all learners are aware of what they have been doing in learning, or they even sometimes do not know how to learn. If this is the problem, learning strategy training can be very beneficial for the learners with this problem. Why should be through strategy training? The answer might lie on the fact that strategy is quite amenable to change, and by nature, teachable as well as learneable (Oxford, 1990. In addition, Nuswantara (2008 also found out that the successful learners (i.e. in learning English were triggered by the courage of using various learning strategies, the more varied the learners are willing to try out, the broader the chance for success. Training is the way that can be selected to present to the learners’ various strategies that they can choose and at the same time employ when learning is taken place. Moreover, by means of training, learners are made aware of the strategy, and they can mend their own strategy, as a result, they become more self - directed rather than dependent. This article attempts to frame out from the perspective of how to bring reading strategies that are applicable for handling various reading content texts to the learners, and present the result of a one-group experimental study. Thus, training is prepared for college learners who are inevitably deal with various English content textbooks and the final aim of the training is to improve learners’ study skills. Then, one group experimental study using correlated sample provides some evidences supporting the effectiveness of the training.

  2. Development of an integrated tobacco endgame strategy.

    van der Eijk, Yvette

    2015-07-01

    In recent years, various tobacco 'endgame' strategies have been suggested as a means to phase out tobacco consumption. Using country examples, this paper discusses three potential strategies: replacing cigarettes with alternative products (harm reduction), denying tobacco sales to people born after a certain year (the tobacco-free generation proposal), and further implementing measures based on the WHO Framework Convention for Tobacco Control (FCTC) treaty. It is argued that all strategies have potential issues that could be avoided by combining them into an integrated, sequential endgame that, first, using measures recommended in the WHO FCTC, creates a climate that facilitates the phasing out of cigarettes; second, implements a generational phase out of cigarette sales; and third, simultaneously permits the regulated use of alternative nicotine products. Thus, integrating ideas from various endgame strategies will result in a more effective, resilient tobacco endgame policy. Published by the BMJ Publishing Group Limited.

    2008-05-01

    It has been suggested that certain theoretically important anomalous results in the area of verbal short-term memory could be attributable to differences in strategy. However there are relatively few studies that investigate strategy directly. We describe four experiments, each involving the immediate serial recall of word sequences under baseline control conditions, or preceded by instruction to use a phonological or semantic strategy. Two experiments varied phonological similarity at a presentation rate of one item every 1 or 2 seconds. Both the control and the phonologically instructed group showed clear effects of similarity at both presentation rates, whereas these were largely absent under semantic encoding conditions. Two further experiments manipulated word length at the same two rates. The phonologically instructed groups showed clear effects at both rates, the control group showed a clear effect at the rapid rate which diminished with the slower presentation, while the semantically instructed group showed a relatively weak effect at the rate of one item per second, and a significant reverse effect with slower presentation. The latter finding is interpreted in terms of fortuitous differences in inter-item rated associability between the two otherwise matched word pools, reinforcing our conclusion that the semantically instructed group were indeed encoding semantically. Implications for controlling strategy by instruction are discussed.

    to check the use of metacognitive reading strategies in children with learning disabilities and determine whether there is a relationship between their use and text comprehension. the study was conducted on 30 children, aged 8 to 12 years, of both genders, divided into experimental group (EG) - 15 children with learning disabilities; and control group (CG) - 15 children without disability. All children were submitted to the Reading Strategies Scale and Prolec text comprehension subtest. The sample was described in mean, median, minimum and maximum values. Comparative analysis was performed between the groups using the Mann-Whitney test. The degree of correlation between variables was verified by Spearman Correlation Analysis. The significance level was set at 5%. across the total scores of the scale, EG performance was lower in all descriptive measures, with a significant difference compared to CG. The EG achieved a performance close to children without difficulties only in global strategies. The correlation between the use of metacognitive strategies and reading comprehension was positive. children with learning disabilities showed deficits in the use of metacognitive reading strategies when compared to children without learning disabilities. The better the performance in reading strategies, the better textual comprehension was and vice versa, suggesting that metacognitive reading skills contribute to reading comprehension.

    Full Text Available Background and Aim: The majority of people experience problems and stressors, such as job layoffs and illnesses during their lives. However, the way people cope with stress varies. According to previous research, use of effective coping strategies can significantly reduce stress and tension. The aim of the present study was to investigate the effectiveness of stress coping strategies on hearing-impaired students.Methods: This is a quasi-experimental study with pre-test, post-test, and control group. The sample consisted of 40 hearing-impaired male students of guidance and high schools of the city of Sari, Iran, in the years 2010 and 2011. They were randomly selected and assigned to two experimental and control groups (n=20. The data collection tool was the General Health Questionnaire-28. The experimental group was administered eight sessions of stress coping strategies based on cognitive-behavioral techniques two hours weekly. Data were analyzed using statistical indices including mean, standard deviation, and two-way analysis of variance.Results: There was a significant difference between the pre-test and post-test scores in the subscales of somatic symptoms, anxiety and insomnia, depression, and social function (p<0.05. Moreover, after the eight sessions the rate of general health of the experimental group was higher than the control group.Conclusion: Stress coping strategies based on cognitive-behavioral techniques increased the general health of hearing-impaired people. Therefore, stress management training should be developed and expanded as an appropriate intervention.

    Ohaja, Magdalena; Dunlea, Margaret; Muldoon, Kathryn

    2013-09-01

    Traditionally, written examination and clinical practice assessments are the main ways of deeming midwifery students fit and competent for practice. Contemporary academics in an effort to engage the students in the learning process have employed alternative teaching and assessment strategies. Among the alternative strategies are group projects after which members of the group are awarded the same grade, and peer assessment. With the purpose of informing the midwifery curricular, we utilised a qualitative descriptive approach to explore midwifery students' experiences and views on the use of group poster presentation for learning and assessment. The participants consisted of a purposive sample of 14 higher diploma midwifery students who were registered in a third level institution in Ireland. Semi-structured individual interviews were conducted following the completion of the poster presentation assessment. Permission to undertake the study was obtained from the college ethics committee. In this paper, we focus on the participants' views of group marking and peer assessment which are among the key elements that emerged in this study. While awarding a group mark was overall accepted, peer assessment proved a more contentious issue. Most of the participants found it challenging marking their friends. Reactions to group marks were very much influenced by the group dynamics. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Drab, Deborah D.

    Grouping students for labs in science classes is a common practice. This mixed methods quasi-experimental action research study examines homogeneous and heterogeneous gender grouping strategies to determine what gender grouping strategy is the most effective in a coeducational science classroom setting. Sixth grade students were grouped in same-gender and mixed-gender groups, alternating each quarter. Over the course of an academic year, data were collected from four sources. The teacher-researcher observed groups working during hands-on activities to collect data on student behaviors. Students completed post-lab questionnaires and an end-of-course questionnaire about their preferences and experiences in the different grouping strategies. Student scores on written lab assignments were also utilized. Data analysis focused on four areas: active engagement, student achievement, student perceptions of success and cooperative teamwork. Findings suggest that teachers may consider grouping students of different ability levels according to different gender grouping strategies to optimize learning.

    1992-01-01

    In response to a mandate in Section 118(c)(3) of the Water Quality Act of 1987, a program called Assessment and Remediation of Contaminated Sediments (ARCS) was established. Four technical work groups were formed. This paper details the research strategy of the Toxicity-Chemistry Work Group.The Work Group's general objectives are to develop survey methods and to map the degree of contamination and toxicity in bottom sediments at three study areas, which will serve as guidance for future surveys at other locations. A related objective is to use the data base that will be generated to calculate sediment quality concentrations by several methods. The information needed to achieve these goals will be collected in a series of field surveys at three areas: Saginaw Bay (MI), Grand Calumet River (IN), and Buffalo River (NY). Assessments of the extent of contamination and potential adverse effects of contaminants in sediment at each of these locations will be conducted by collecting samples for physical characterization, toxicity testing, mutagenicity testing, chemical analyses, and fish bioaccumulation assays. Fish populations will be assessed for tumors and external abnormalities, and benthic community structure will be analyzed. A mapping approach will use low-cost indicator parameters at a large number of stations, and will extrapolate by correlation from traditional chemical and biological studies at a smaller number of locations. Sediment toxicity testing includes elutriate, pore water and whole sediment bioassays in a three-tiered framework. In addition to the regular series of toxicity tests at primary mater stations, some stations are selected for a more extensive suite of tests.

    1997-09-01

    This document fulfills the requirements of the Hanford Federal Facility Agreement and Consent Order, Milestone M-13-81, to develop a concise statement of strategy that describe show the Hanford Site groundwater remediation will be accomplished. The strategy addresses objectives and goals, prioritization of activities, and technical approaches for groundwater cleanup. The strategy establishes that the overall goal of groundwater remediation on the Hanford Site is to restore groundwater to its beneficial uses in terms of protecting human health and the environment, and its use as a natural resource. The Hanford Future Site Uses Working Group established two categories for groundwater commensurate with various proposed landuses: (1) restricted use or access to groundwater in the Central Plateau and in a buffer zone surrounding it and (2) unrestricted use or access to groundwater for all other areas. In recognition of the Hanford Future Site Uses Working Group and public values, the strategy establishes that the sitewide approach to groundwater cleanup is to remediate the major plumes found in the reactor areas that enter the Columbia River and to contain the spread and reduce the mass of the major plumes found in the Central Plateau

    To understand the coping strategies used by teachers with vocal complaints, compare the differences between those who seek and those who do not seek voice therapy, and investigate the relationships among coping and voice perceptual analysis, coping and signs and symptoms of voice, and coping and participation restrictions and limitations in vocal activities. Cross-sectional nonrandomized prospective study with control group. Ninety female teachers participated in the study, of similar ages, divided into three groups: group 1 (G1) comprised 30 teachers with vocal complaints who sought voice therapy, group 2 (G2) comprised 30 teachers with vocal complaints who never sought voice therapy, and group 3 (G3) comprised 30 teachers without vocal complaints. The following analysis were conducted: identification and characterization questionnaire, addressing personal and occupational description, recording speech material for voice perceptual analysis, Voice Signs and Symptoms Questionnaire, Voice Activity and Participation Profile (VAPP), and Voice Disability Coping Questionnaire (VDCQ)-Brazilian Version. In relation to the voice perceptual analysis, there was statistically significant difference between the groups with vocal complaint (G1+G2), which had showed voices with mild-to-moderate deviation, and the group without vocal complaint (G1), which showed voices within the normal variability of voice quality (mean for G1 = 49.9, G2 = 43.7, and G3 = 32.3, P Teachers with vocal complaints who looked for voice therapy use more coping strategies. Moreover, they present a tendency to use more problem-focused coping strategies. Voice symptoms prompt the teachers into seeking treatment; however, they are not correlated with the coping itself. In general, the higher the perception of limitation and restriction of participating in vocal activities, the greater the use of coping strategies. Copyright © 2014 The Voice Foundation.

    Full Text Available This research can be described as an experimental quantitative one including: a strategy training; two homogenous experimental groups with different levels of proficiency; and two homogenous control groups. The subjects are 60 Spanish high school students, who have been selected after taking the Oxford Quick Placement-Test. The study aims at investigating the possible relationship between the effect of the strategy training and the subjects' level of proficiency. It is also designed to analyze the effect of the training on the use of communication strategies in the written medium. It is meant to study the effect of the strategy training on the subjects' writing skill in English. The results show that the students' level of proficiency exerts a strong effect on the subjects' use of written communication strategies (CSs and on their strategy preference in written production. They also demonstrate how strategy training improves the subjects' written communication ability.

    Objectives We used an individual-based model to evaluate the effects of hypothetical prevention interventions on HIV incidence trajectories in a concentrated, mixed epidemic setting from 2011 to 2021, and using Cabo Verde as an example. Methods Simulations were conducted to evaluate the extent to which early HIV treatment and optimization of care, HIV testing, condom distribution, and substance abuse treatment could eliminate new infections (i.e., reduce incidence to less than 10 cases per 10,000 person-years) among non-drug users, female sex workers (FSW), and people who use drugs (PWUD). Results Scaling up all four interventions resulted in the largest decreases in HIV, with estimates ranging from 1.4 (95%CI:1.36–1.44) per 10,000 person-years among non-drug users to 8.2 (95%CI:7.8–8.6) per 10,000 person-years among PWUD in 2021. Intervention scenarios targeting FWS and PWUD also resulted in HIV incidence estimates at or below 10 per 10,000 person-years by 2021 for all population sub-groups. Conclusions Our results suggest that scaling up multiple interventions among entire population is necessary to achieve elimination. However, prioritizing key populations with this combination prevention strategy may also result in a substantial decrease in total incidence. PMID:25838121

    Full Text Available In this contribution, several strategies of force control have been proposed to be implemented and evaluated in ROBOCLIMBER, a quadruped robot of large dimensions. A first group of strategies proposed in this paper is based on impedance control, which is intended to adapt the foot-ground contact forces according to the experimentally specified damping ratio and the undamped natural frequency. A second control strategy of interest for many practical cases is called the parallel force/position control, which has one inner loop position control and two external control loops, one of force and another of position. A third group of control strategies is the posture stabilization for ROBOCLIMBER using the feedback of the ZMP calculation and the position of its legs. Finally, a control strategy for the control of a quasi-static gait using ZMP feedback is proposed and tested by simulation.

    Full Text Available The present study explored the vocabulary learning strategies used by Iranian EFL learners and Marine Engineering (ME students by using the categorization of vocabulary learning strategies proposed by Schmitt (1997. A vocabulary learning strategies questionnaire was administered to 30 EFL learners and 43 ME students. Then, the strategies used by each group were determined and the two groups were compared with each other. It was found that both groups used determination strategies more frequently than social strategies for discovering a new word’s meaning. The most frequently used discovery strategy by both groups was found to be “bilingual dictionary”. The second and third most frequently used strategy for discovery by EFL learners and ME students was found to be “monolingual dictionary” and “guess from textual context”, respectively. It was also revealed that EFL learners used memory strategies more frequently than other strategies for consolidating the meaning of new words and ME students used cognitive strategies the most frequently. Both groups were found to use “verbal repetition” more frequently than all other consolidation strategies. The second most frequently used strategy by EFL learners was “use Englishlanguage media” whilst for ME students they were “written repetition” and “word lists”. The comparison of the strategy use by the participants in the two groups showed no significant difference.

    University lecturers often complain about their students’ lack of learning strategies, but not many universities in Spain offer specific courses in this area. Studies on their effectiveness are also rare. This study presents the results of a Learning Strategies Course implemented at the School of Teacher Training and Education, University of Oviedo, Spain. A quasi-experimental design was used with an experi-mental (n = 60) and a control group (n = 57) of students on the Educational Psychology course. A Spanish adaptation of the Motivated Strategies for Learning Questionnaire (MSLQ): the CEAMR2 was used as a pre and post-test measure. Group A (EG) received training in learning strategies, while group B (CG) received no training. Post-test measures showed significant differences in five out of the ten learning strategies assessed: elaboration, organization, repetition, self-questioning and study space, and also an improvement in one out of the six motivational scales: control of learning beliefs. The results suggest that learning strategies courses with proven effectiveness should be offered to university students.

    Complex social behaviors lie at the heart of many of the challenges facing evolutionary biology, sociology, economics, and beyond. For evolutionary biologists the question is often how group behaviors such as collective action, or decision making that accounts for memories of past experience, can emerge and persist in an evolving system. Evolutionary game theory provides a framework for formalizing these questions and admitting them to rigorous study. Here we develop such a framework to study the evolution of sustained collective action in multi-player public-goods games, in which players have arbitrarily long memories of prior rounds of play and can react to their experience in an arbitrary way. We construct a coordinate system for memory-m strategies in iterated n-player games that permits us to characterize all cooperative strategies that resist invasion by any mutant strategy, and stabilize cooperative behavior. We show that, especially when groups are small, longer-memory strategies make cooperation easier to evolve, by increasing the number of ways to stabilize cooperation. We also explore the co-evolution of behavior and memory. We find that even when memory has a cost, longer-memory strategies often evolve, which in turn drives the evolution of cooperation, even when the benefits for cooperation are low.

    Full Text Available This Research Paper aims to analyse in depth the global propaganda strategy of the so-called “Islamic State” (IS by looking at the methods through which this grand strategy is carried out as well as the objectives that IS wants to achieve through it. The authors first discuss IS’ growth model, explaining why global expansion and recruitment of foreign fighters are pivotal to IS success. Having in mind this critical role, the authors then explore the narratives and themes used by the group to mobilise foreign fighters and jihadists groups. Third, the paper analyses how IS deploys its narratives in those territories where it has established a foothold. Fourth, it outlines IS’ direct engagement strategy and how it is used to facilitate allegiance of other jihadist groups. The final section of the paper offers a menu of policy options that stakeholders can implement to counter IS’ global propaganda efforts.

    2014-09-01

    Cognitive load theory was used to hypothesize that a general problem-solving strategy based on a make-as-many-moves-as-possible heuristic could facilitate problem solutions for transfer problems. In four experiments, school students were required to learn about a topic through practice with a general problem-solving strategy, through a conventional problem solving strategy or by studying worked examples. In Experiments 1 and 2 using junior high school students learning geometry, low knowledge students in the general problem-solving group scored significantly higher on near or far transfer tests than the conventional problem-solving group. In Experiment 3, an advantage for a general problem-solving group over a group presented worked examples was obtained on far transfer tests using the same curriculum materials, again presented to junior high school students. No differences between conditions were found in Experiments 1, 2, or 3 using test problems similar to the acquisition problems. Experiment 4 used senior high school students studying economics and found the general problem-solving group scored significantly higher than the conventional problem-solving group on both similar and transfer tests. It was concluded that the general problem-solving strategy was helpful for novices, but not for students that had access to domain-specific knowledge.

    Collaborative research teams are an attractive means of conducting nursing research in the clinical setting because of the many opportunities that collaboration can supply. These opportunities include a chance to: (1) network with other nurses who have similar interests, (2) share knowledge and expertise for designing clinical studies that directly affect daily practice, (3) develop instruments, (4) write grant proposals, (5) collect and analyze data, and (6) prepare manuscripts for publication. The effectiveness of research teams, however, is strongly influenced by group functioning. This article describes the functioning of a collaborative family interventions research team of nursing faculty members and CNSs at a large Midwestern university setting. The formation of the group and membership characteristics are described, along with strategies used to identify the research focus and individual and group goals. Aspects related to the influence of the group on members and the internal operations of the group are also addressed. Future strategies to be explored will focus on the size of the group and joint authorship issues. The authors also set forth a number of recommendations for development of collaborative research groups.

We define a new cross entropy measure under interval neutrosophic set (INS environment, which we call IN-cross entropy measure and prove its basic properties. We also develop weighted IN-cross entropy measure and investigats its basic properties. Based on the weighted IN-cross entropy measure, we develop a novel strategy for multi attribute group decision making (MAGDM strategy under interval neutrosophic environment. The proposed multi attribute group decision making strategy is compared with the existing cross entropy measure based strategy in the literature under interval neutrosophic set environment. Finally, an illustrative example of multi attribute group decision making problem is solved to show the feasibility, validity and efficiency of the proposed MAGDM strategy.

    The aim of this study was to describe how persons with rheumatoid arthritis (RA) of working age experience and handle their fatigue in everyday life. Six focus group discussions were conducted focusing on experiences of fatigue in 25 persons with RA (19 women, 6 men), aged 20-60 years. The discussions were recorded, transcribed verbatim, and analyzed according to qualitative content analysis. The analyses resulted in four categories. (1) Perception of fatigue: Fatigue was experienced different from normal tiredness, unpredictable, and overwhelming. It was associated with negative emotions, changed self-image, and fears. Feelings of frustration and shame were central when the persons were forced to omit valued life activities. (2) Consequences due to fatigue: The fatigue caused changes in cognitive ability, ability to act, and overall activity pattern where the increased need for rest and sleep caused an imbalance in daily life. The participants struggled not to let the fatigue interfere with work. The fatigue also brought negative consequences for their significant others. (3) Communicating fatigue: Fatigue was difficult to gain understanding for, and the participants adjusted their communication accordingly; it was important to keep up appearances. During medical consultation, fatigue was perceived as a factor not given much consideration, and the participants expressed taking responsibility for managing their fatigue symptoms themselves. (4) Strategies to handle fatigue: Strategies comprised conscious self-care, mental strategies, planning, and prioritizing. Fatigue caused considerable health problems for persons with RA of working age: negative emotions, imbalance in daily life due to increased need for rest, and difficulties gaining understanding. This draws attention to the importance of developing new modes of care to address fatigue in RA. Person-centered care to improve balance in life may be one approach needing further investigations.

    Research about the implementation of the Peer Assisted Learning (PAL) strategy in Plant Physiology lecture has carried out, in which it aims to improve students’ physiologic literacy. The PAL strategy began with a briefing by the lecturers to the students tutor about pretest questions, followed by the interaction between student tutors with their peers to discuss response problems, terminated by answering responsiveness questions individually. This study used a quasi-experimental method, one - group pre-test post-test design. This design includes a group of students observed in the pre-test phase (tests carried out before PAL treatment) which is then followed by treatment with PAL and ends with post-test. The other students group (control) was given the pre-test and post-test only. The results showed that the PAL strategy can increase student’s physiologic literacy significantly. One of the weaknesses of students’ physiologic literacy is that they have not been able to read the graph. The faculties are encouraged to begin introducing and teaching material using a variety of strategies with scientific literacy aspects, for example teaching research-based material. All students respond positively to the PAL strategy.

    Full Text Available The present experimental study primarily aimed at examining the effect of presentation strategy on reading comprehension of Iranian intermediate EFL learners. To determine the effect of this strategy, 61 students who enrolled in English Language Center of Chabahar Maritime University were initially selected and then divided randomly into two classes one as an experimental group and the other one as the control group. The homogeneity of their proficiency level was established via the administration of a TOEFL (the PBT proficiency test. A reading comprehension test as pre-test administered to the subjects of both groups one week before the initiation of the study. The experimental group used the strategy three sessions each week for ten weeks, while the control group was trained based on the ordinary approaches of teaching reading comprehension. Presentation strategy was worked for every two weeks during the experiment and then at the end of each two-week instruction, an immediate posttest was administered according to the strategy worked. At the end of the study, a post-test was administered to both groups. The statistical techniques being applied were Paired Sample t-test and Independent Sample t-test. The results of the study revealed that presentation strategy had significant effect on promoting reading comprehension of intermediate EFL learners.

    Full Text Available An effective reading comprehension process demands a strategy to enhance the cognitive ability to digest text information in the effort to elicit meaning contextually. In addition, the role of emotions also influences the efficacy of this process, especially in narrative text comprehension. This quasi-experimental study aims to observe students’ performance in the Reading Comprehension Test resulting from Emotional Literacy-Based Reading Comprehension Strategy (ELBRCS, which is a combination of cognitive and affective strategies. This study involved 90 students, whereby 45 students were clustered in the Experimental Group and received the ELBRCS intervension. The remaining 45 students were placed in the Control Group and underwent the conventional strategy (prevalent classroom method.The students’ reading comprehension performance was measured using the Reading Comprehension Test (RCT. The findings show that the experimental group received a higher score than the control group for RCT. The intervention has successfully increased student’s Reading Comprehension from literal comprehension to higher levels of comprehension i.e. inferential, evaluative and appreciative levels, as indicated by Barret’s Taxonomy.

    Full Text Available The present study attempted to investigate the possible impacts of Individual Concept Mapping (ICM and Collaborative Concept Mapping (CCM strategies on Iranian EFL learners' reading comprehension. For this purpose, 90 pre-intermediate female language learners ranged between 12 to 17 years of age were selected to randomly assign into ICM, CCM and Control groups in this study. After taking Key English Test (KET, the ICM and CCM groups received EFL reading materials presented and practiced with ICM and CCM strategies, respectively, while the Control group received only conventional instructions to reading comprehension. After conducting the treatment, all participants took a Concept Mapping post-test constructed by the researchers. The hypothetical assumptions in this study were in favor of ICM and CCM strategies to improve the Iranian EFL learners’ reading comprehension. Statistics supported the outperformance of the ICM and CCM groups comparing to Control group who received convention PPP teaching techniques on Concept Mapping post-test. However, the superiority of neither strategies was statistically proved so that no meaningful difference between the reading comprehension of the ICM and CCM groups were detected. Therefore, the researchers failed to determine which strategy caused a better or higher impact. Some pedagogical implications and recommended topics for further research were provided to the motivated researchers.

  1. Strategies to address transition costs in the electricity industry

    Energy Technology Data Exchange (ETDEWEB)

    Baxter, L.; Hadley, S.; Hirst, E.

    1996-07-01

    Transition costs are the potential monetary losses that electric- utility shareholders, ratepayers, or other parties might experience because of structural changes in the electricity industry. Regulators, policy analysts, utilities, and consumer groups have proposed a number of strategies to address transition costs, such as immediately opening retail electricity markets or delaying retail competition. This report has 3 objectives: identify a wide range of strategies available to regulators and utilities; systematically examine effects of strategies; and identify potentially promising strategies that may provide benefits to more than one set of stakeholders. The many individual strategies are grouped into 6 major categories: market actions, depreciation options, rate-making actions, utility cost reductions, tax measures, and other options. Of the 34 individual strategies, retail ratepayers have primary or secondary responsibility for paying transition costs in 19 of the strategies, shareholders in 12, wheeling customers in 11, taxpayers in 8, and nonutility suppliers in 4. Most of the strategies shift costs among different segments of the economy, although utility cost reductions can be used to offset transition costs. Most of the strategies require cooperation of other parties, including regulators, to be implemented successfully; financial stakeholders must be engages in negotiations that hold the promise of shared benefits. Only by rejecting ``winner-take-all`` strategies will the transition-cost issue be expeditiously resolved.

    Little information is available regarding the extent of strategy use and factors that affect strategy use in amnestic mild cognitive impairment (aMCI). This study aimed to compare spontaneous strategy use and beliefs about the controllability of memory between aMCI and healthy older adult (HOA) samples and to explore the relationships between beliefs, strategy use, and memory performance for both groups. The aMCI and HOA groups each composed of 60 individuals matched for age and education. The Memory Controllability Inventory was used to assess control beliefs, and the extent of semantic clustering on a list-learning task provided a measure of spontaneous strategy use. The aMCI group endorsed lower control beliefs and demonstrated poorer semantic clustering and memory performance compared with the HOA group. Although strategy use partially mediated the control beliefs-memory performance relationship for the HOA group, this was not replicated for the aMCI group. Despite the weak relationship between control beliefs and strategy use, and control beliefs and memory performance for the aMCI group, the strong relationship between strategy use and memory performance provides impetus for further research into factors that can be used as a means of enhancing strategy use in interventions for aMCI.

    Full Text Available The present study set out to investigate the differences between EAP (English for Academic Purposes students of Humanities and Engineering in terms of vocabulary strategy choice and use. One hundred and five undergraduate Iranian students (39 students from Engineering Faculty and 66 from Humanities Faculty studying at Bu-Ali Sina University Hamedan, during the academic year of 2011–2012 participated in this study. For data collection purposes, a pilot-tested factor-analyzed five-point Likert-scale vocabulary learning strategies questionnaire (VLSQ containing 45 statements was adopted. The results of independent samples t-test indicated that, overall, the two groups were not significantly different in the choice and use of vocabulary learning strategies. However, running Chi square analyses, significant differences were found in individual strategy use in 6 out of 45 strategies. That is, while Humanities students used more superficial and straightforward strategies like repetition strategy and seeking help from others, the Engineering students preferred much deeper, thought-provoking and sophisticated strategies like using a monolingual dictionary and learning vocabulary through collocations and coordinates. Further, the most and the least frequently used vocabulary learning strategies by the two groups were specified, out of which only two strategies in each category were commonly shared by both groups. The possible reasons why the results have turned out to be so as well as the implications of the study are discussed in details in the paper.

    Porter's generic strategies characterize organizations in terms of their competitiveness, and are related to the performance of the organization. The aim of this study was to analyze the Porter's generic strategies and their effect on performance in the context of the Slovak hospital industry. Acute care hospitals with more than 30 beds were included into the study. National institutes providing specialized service were excluded from the study. Strategy and performance were evaluated on the basis of self-reported questionnaires, completed by chief administrators of hospitals (total 76 completed questionnaires were obtained, out of 81 distributed, i.e. 94% response rate). The cluster analysis was used for the identification of strategic orientation. Performance differences across strategic groups were tested using multivariate analysis of covariance (MANCOVA). The hierarchical cluster analysis uncovered a four-group taxonomy of hospitals: the group "Focused Cost Leadership" included 33% of hospitals, the group "Stuck-in-the middle" 49%, the group "Wait and See" 13% and the group "Cost leadership" 5%. Significant differences in performance were related to the Porter's pure, or hybrid strategies, respectively. In terms of industry evolution, the Slovak hospital industry could be characterized as fragmented, having a large number of small and medium size mainly state owned hospitals, with absence of market leaders, and with high exit barriers (mainly social and political) that hold back consolidation.

    Although information and communication technology interventions appear to be a promising means of reducing the health inequality gap in overweight and obesity prevention, research on information and communication technology interventions is lacking outside the Anglo-Saxon world. The aim of this study was to assess the reach and acceptability of 2 information and communication technology interventions delivered as part of a French nutritional program: an SMS text messaging (short message service, SMS) attendance-reminder for collective sessions strategy and a Facebook challenge group. This study sample comprised 262 socially less advantaged overweight adolescents aged between 13 and 18 years. The information and communication technology interventions were carried out during the 2013-2014 academic year in 33 French state-run schools. For the SMS attendance-reminder for collective sessions strategy, at the start of the academic year, adolescents were asked to give their mobile number. SMS attendance-reminders were sent shortly before each of the 5 collective sessions. For the Facebook challenge group, adolescents were invited to join a closed Facebook group in which challenges on physical activity and on diet were posted weekly. Process data and 2 sets of face-to-face interviews were also used to interpret participation rates and access to Facebook. Appreciation for both interventions was evaluated by a questionnaire at the end of the academic year. Of the recruited adolescents, 79.0% (207/262) gave their mobile number, reflecting high access to a mobile phone. Giving a number was significantly more likely for girls (odds ratio [OR] 2.1, 95% CI 1.1-3.9; P=.02) and adolescents in a vocational or general high school as opposed to middle school (OR 1.0, 95% CI 0.4-2.7; OR 0.2, 95% CI 0.1-0.5; PFacebook challenge group, which implies having a Facebook account or being able to have access to one.

    Patients with synchronous colorectal liver metastases (sCRLM) are increasingly operated with liver resection before resection of the primary cancer. The aim of this study was to compare outcomes in patients following the liver-first strategy and the classical strategy (resection of the bowel first) using prospectively registered data from two nationwide registries. Clinical, pathological and survival outcomes were compared between the liver-first strategy and the classical strategy (2008-2015). Overall survival was calculated. A total of 623 patients were identified, of which 246 were treated with the liver-first strategy and 377 with the classical strategy. The median follow-up was 40 months. Patients chosen for the classical strategy more often had T4 primary tumours (23% vs 14%, P = 0.012) and node-positive primaries (70 vs 61%, P = 0.015). The liver-first patients had a higher liver tumour burden score (4.1 (2.5-6.3) vs 3.6 (2.2-5.1), P = 0.003). No difference was seen in five-year overall survival between the groups (54% vs 49%, P = 0.344). A majority (59%) of patients with rectal cancer were treated with the liver-first strategy. The liver-first strategy is currently the dominant strategy for sCRLM in patients with rectal cancer in Sweden. No difference in overall survival was noted between strategies.

  16. Groups, Pricing, and Cost of Debt: Evidence from Turkey

    Directory of Open Access Journals (Sweden)

    A. Melih Küllü

    2018-03-01

    Full Text Available The paper examines the impact of business group affiliation on cost of loans in an emerging market setting. It focuses on operational strategy, organizational structure and internationalization policies of business group firms and their impact on borrowing cost of affiliated firms. Bank loans are a dominant source of corporate funding in emerging markets, in which business groups exist as leading economic entities. Yet, the impact of belonging to a group on the firm’s cost of debt has not been studied in depth. Our results reveal that the extent of group affiliation, government ownership, and diversification increase the cost of loans. However, a group bank is advantageous in terms of borrowing, and decreases the cost of loans. While foreign ownership is beneficial in terms of pricing, being affiliated with a foreign group is not. Being a financial firm and being cross-listed are not significantly associated with bank loan terms. Borrowing costs are thus influenced in various ways by organizational structure, operational strategies, and global policies of business groups and affiliates. Therefore, business groups may benefit from strategically implementing policies and selecting loan applicant firms.

From 10-12 September, some 500 physicists went to Krakow to discuss their wishes for the future of the field as input to the CERN Council’s strategy group.   The strategy group is tasked with updating the European Strategy for Particle Physics adopted by Council in 2006, taking into account developments in the field over the last six years. Discussions were wide ranging, and included input from the Americas and Asia. These were particularly important, since it’s vital for the field that Europe’s strategy is in synch with what’s happening elsewhere in the world. I hardly need to tell you that the years since 2006 have seen monumental changes in particle physics, notably the discovery by ATLAS and CMS of a particle consistent with the Higgs boson. But it’s not only the high-energy frontier of the LHC that has provided new results. There have been important advanc...

  20. Group purchasing: an overview.

    Science.gov (United States)

    Wetrich, J G

    1987-07-01

    The various types and operational methods of purchasing groups are described, and evaluation of groups is discussed. Since group purchasing is increasing in popularity as a method of controlling drug costs, community and hospital pharmacy managers may need to evaluate various groups to determine the appropriateness of their services. Groups are categorized as independent, system based, or alliance or association based. Instead of "purchasing," some groups develop contracts for hospitals, which then purchase directly from the vendor. Aside from this basic difference between groups that purchase and groups that contract, comparisons among groups are difficult because of the wide variation in sizes and services. Competition developing from diversification among groups has led to "super groups," formed from local and regional groups. In evaluating groups, advantages and disadvantages germane to accomplishing the member's objectives must be considered. To ensure a group's success, members must be committed and support the group's philosophies; hospital pharmacists must help to establish a strong formulary system. To select vendors, groups should develop formal qualification and selection criteria and should not base a decision solely on price. The method of solicitation (bidding or negotiating), as well as the role of the prime vendor, should be studied. Legal implications of group purchasing, especially in the areas of administrative fees and drug diversion, must also be considered. The most advantageous group for each organization will include members with common missions and will be able to implement strategies for future success.

    Full Text Available The present study investigated the effect of brain dominance on the use of Language learning speaking strategies. One hundred forty two undergraduate students of Shiraz University, Iran, participated in this study. The Hemispheric Dominance Test (HDT was employed to categorize participants as right-, left- and whole-brain dominant, and a Speaking Strategy Questionnaire was administered to evaluate their use of speaking strategies. The results were analyzed using a one-way between groups analysis of variance (ANOVA to investigate whether there were any significant differences between the three brain dominant groups in their overall use of speaking strategies. A MANOVA was also run to investigate whether the groups had preferences regarding the use of any particular strategy type. Results indicated a statistically significant difference between the whole brain dominant participants and both left brain and right brain dominant learners for using compensation speaking strategies. To teach and learn more effectively, instructors and learners need to better understand and appreciate individual differences and how they can affect the learning process. They could find ways to combine activities that accommodate both left and right brain learners, employing not only the usual linear, verbal model, but also the active, image-rich, visuo-spatial models so that learners would be able to use both hemispheres.

    We examined the self-reported use of reading, study, and learning strategies in university students with a history of reading difficulties (HRD; n = 77) and with no history of reading difficulties (NRD; n = 295). We examined both between-groups differences in strategy use and strategy use as a predictive measure of academic success. Participants completed online questionnaires regarding reading history and strategy use. GPA and frequency of use of academic support services were also obtained for all students. University students with HRD reported a different profile of strategy use than their NRD peers, and self-reported strategy use was differentially predictive of GPA for students with HRD and NRD. For students with HRD, the use of metacognitive reading strategies and the use of study aids predicted academic success. Implications for university student services providers are discussed. © Hammill Institute on Disabilities 2015.

    Full Text Available The aim of this quasi-experimental study was to investigate the impact of a metacognitive training program on university freshmen’s reading comprehension skill in a three-credit General English (GE Course. The participants included eight groups of freshmen, in four disciplines: Management, Psychology, Mechanical Engineering and Computer Engineering. They were randomly assigned as four experimental and four control groups, each including approximately 30 participants. The same materials were taught to all groups after their initial homogeneity in English was assessed via Analysis of Variance of the pre-test scores obtained from a Key English Test (KET. In the experimental groups, one whole session was devoted to explicitly teaching three sets of metacognitive strategies and five reading strategies: skimming, scanning, previewing, using context clues, and making inferences. These groups also received metacognitive awareness-raising while applying the strategies in each reading lesson for six sessions. The analyses of the research data revealed that metacognitive strategy training promoted the participants’ learning when integrated with a reading-focused GE course regardless of their gender and a small effect from discipline. The findings have implications for teachers, materials developers, and teacher trainers.

    Full Text Available This action research study evaluated the effects of literacy strategies on academic achievement, motivation, and engagement of eighth-grade social studies students. Incorporating literacy strategies included teaching students to construct meaning, think critically, and build content knowledge, while stimulating their interests, using multiple texts and technology, and providing collaborative opportunities and high engagement during instructional activities. Students were divided into a literacy group and a direct instruction group with each class being taught the same content. Literacy strategies were incorporated in one class, and direct instruction activities were used in the other class. Results were determined using pre and posttest scores, a student motivation questionnaire, and a student engagement checklist. Results indicated significantly higher student achievement and engagement when literacy strategies were a part of the social studies instruction. Motivation also increased when literacy strategies were used. Literacy instruction was a beneficial strategy to improve student achievement, motivation, and engagement.

    Effectiveness of the condensed Dialectical Behavior Therapy Skills Training Group (DBTSTG) was compared to the Cognitive Therapy Group (CTG) in reducing depression and suicide reattempt, and modifying emotion regulation strategies among those with borderline personality disorder (BPD). Eighty-two depressed BPD college students with a suicidal history within the past six-months were randomly allocated to DBTSTG or CTG. Both groups had similar reductions in suicide reattempts and depression after the intervention and 6-month follow-ups. However, the CTG showed improvements in cognitive errors, but the DBTSTG revealed increases in acceptance and decreases in suppression scores. Both groups were effective in decreasing depression and suicide reattempt in BPD college students, probably through increasing adaptive antecedent-focused or response-focused strategies of emotion regulation, respectively.

    2007-10-01

    Low-income African Americans who live in rural areas of the Deep South are particularly vulnerable to diseases associated with unhealthy energy imbalance. The Centers for Disease Control and Prevention (CDC) has suggested various physical activity strategies to achieve healthy energy balance. Our objective was to conduct formal, open-ended discussions with low-income African Americans in the Mississippi Delta to determine 1) their dietary habits and physical activity levels, 2) their attitudes toward CDC's suggested physical activity strategies, and 3) their suggestions on how to achieve CDC's strategies within their own environment. A qualitative method (focus groups) was used to conduct the study during 2005. Prestudy meetings were held with African American lay health workers to formulate a focus group topic guide, establish inclusion criteria for focus group participants, select meeting sites and times, and determine group segmentation guidelines. Focus groups were divided into two phases. All discussions and focus group meetings were held in community centers within African American neighborhoods in the Mississippi Delta and were led by trained African American moderators. Phase I focus groups identified the following themes: overeating, low self-esteem, low income, lack of physical exercise, unhealthy methods of food preparation, a poor working definition of healthy energy balance, and superficial knowledge of strategies for achieving healthy energy balance. Phase 2 focus groups identified a preference for social support-based strategies for increasing physical activity levels. Energy balance strategies targeting low-income, rural African Americans in the Deep South may be more effective if they emphasize social interaction at the community and family levels and incorporate the concept of community volunteerism.

    Opioid-induced bowel dysfunction (OIBD) is an increasing problem due to the common use of opioids for pain worldwide. It manifests with different symptoms, such as dry mouth, gastro-oesophageal reflux, vomiting, bloating, abdominal pain, anorexia, hard stools, constipation and incomplete evacuation. Opioid-induced constipation (OIC) is one of its many symptoms and probably the most prevalent. The current review describes the pathophysiology, clinical implications and treatment of OIBD. The Nordic Working Group was formed to provide input for Scandinavian specialists in multiple, relevant areas. Seven main topics with associated statements were defined. The working plan provided a structured format for systematic reviews and included instructions on how to evaluate the level of evidence according to the GRADE guidelines. The quality of evidence supporting the different statements was rated as high, moderate or low. At a second meeting, the group discussed and voted on each section with recommendations (weak and strong) for the statements. The literature review supported the fact that opioid receptors are expressed throughout the gastrointestinal tract. When blocked by exogenous opioids, there are changes in motility, secretion and absorption of fluids, and sphincter function that are reflected in clinical symptoms. The group supported a recent consensus statement for OIC, which takes into account the change in bowel habits for at least one week rather than focusing on the frequency of bowel movements. Many patients with pain receive opioid therapy and concomitant constipation is associated with increased morbidity and utilization of healthcare resources. Opioid treatment for acute postoperative pain will prolong the postoperative ileus and should also be considered in this context. There are no available tools to assess OIBD, but many rating scales have been developed to assess constipation, and a few specifically address OIC. A clinical treatment strategy for OIBD

    Based on learning motivation theory and metacognitive theory, the present study reports questionnaire surveys on cor-relation between motivation orientations and listening metacognitive strategies among 117 English majors. Findings suggest that:1) English majors are mainly stimulated by instrumental motivation and show bias towards planning and evaluation strate-gy in listening comprehension;2) there is a significant positive correlation between instrumental motivation and strategy of plan-ning and evaluation;3) significant difference between high motive group and low motive group only exists in planning and eval-uation strategy. Therefore, teachers are encouraged to help students strengthen the training of listening metacognitive strategies form long-lasting motivation and promote listening proficiency as well as self-learning ability.

  3. The Process Model of Group-Based Emotion: Integrating Intergroup Emotion and Emotion Regulation Perspectives.

    Goldenberg, Amit; Halperin, Eran; van Zomeren, Martijn; Gross, James J

    2016-05-01

    Scholars interested in emotion regulation have documented the different goals and strategies individuals have for regulating their emotions. However, little attention has been paid to the regulation of group-based emotions, which are based on individuals' self-categorization as a group member and occur in response to situations perceived as relevant for that group. We propose a model for examining group-based emotion regulation that integrates intergroup emotions theory and the process model of emotion regulation. This synergy expands intergroup emotion theory by facilitating further investigation of different goals (i.e., hedonic or instrumental) and strategies (e.g., situation selection and modification strategies) used to regulate group-based emotions. It also expands emotion regulation research by emphasizing the role of self-categorization (e.g., as an individual or a group member) in the emotional process. Finally, we discuss the promise of this theoretical synergy and suggest several directions for future research on group-based emotion regulation. © 2015 by the Society for Personality and Social Psychology, Inc.

    Hawk-dove games have been extensively used to predict the conditions under which group-living animals should defend their resources against potential usurpers. Typically, game-theoretic models on aggression consider that resource defense may entail energetic and injury costs. However, intruders may also take advantage of owners who are busy fighting to sneak access to unguarded resources, imposing thereby an additional cost on the use of the escalated hawk strategy. In this article we modify the two-strategy hawk-dove game into a three-strategy hawk-dove-sneaker game that incorporates a distraction-sneaking tactic, allowing us to explore its consequences on the expected level of aggression within groups. Our model predicts a lower proportion of hawks and hence lower frequencies of aggressive interactions within groups than do previous two-strategy hawk-dove games. The extent to which distraction sneakers decrease the frequency of aggression within groups, however, depends on whether they search only for opportunities to join resources uncovered by other group members or for both unchallenged resources and opportunities to usurp.

    Radiology expertise is dependent on the use of efficient search strategies. The aim of this study is to investigate the effect of teaching search strategies on trainee's accuracy in detecting lung nodules at computed tomography. Two search strategies, "scanning" and "drilling," were tested with a randomized crossover design. Nineteen junior radiology residents were randomized into two groups. Both groups first completed a baseline lung nodule detection test allowing a free search strategy, followed by a test after scanning instruction and drilling instruction or vice versa. True positive (TP) and false positive (FP) scores and scroll behavior were registered. A mixed-design analysis of variance was applied to compare the three search conditions. Search strategy instruction had a significant effect on scroll behavior, F(1.3) = 54.2, P search (M = 15.3, SD = 4.6), t(18) = 4.44, P search. FP scores for drilling (M = 7.3, SD = 5.6) were significantly lower than for free search (M = 12.5, SD = 7.8), t(18) = 4.86, P < 0.001. Teaching a drilling strategy is preferable to teaching a scanning strategy for finding lung nodules. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

    Full Text Available OBJECTIVE: This study identified strategies for promoting breastfeeding involving pregnant women, breastfeeding women and actors of the social support network for the breastfeeding process. METHODS: This qualitative study was guided by action research and the focal group technique to collect data. Focal Group 1 consisted of four pregnant and six breastfeeding women; Focal Group 2 consisted of six family members; and Focal Group 3 consisted of thirteen health professionals. The focal groups were guided by the following questions: What breastfeeding promotion and support actions should be done? How should they be performed? Who should perform them? The conversation sunder went thematic content analysis and were interpreted in the light of Paulo Freire's theoretical constructs: dialogue, ethics and problematization. RESULTS: Four themes were emerged from the conversations: dialogue-based educational actions involving the social support network during the vital cycle; educational actions in schools; educational actions in the media; ongoing counseling at Family Health Units. CONCLUSION: The constructed strategies were centered on dialogue and active listening. Both should be present during the entire vital cycle and in the Family Health Strategy, and involve all actors of the social support network. These strategies may disrupt the unidirectional transmission of the educational practices that promote breastfeeding.

    Full Text Available Standardized reading comprehension tests (RCTs usually consist of a small number of texts each accompanied by several multiple-choice questions, with texts and questions simultaneously presented. The score the common measure of reading comprehension ability in RCTs is the score. Literature review suggests that strategies subjects employ may influence their performance on RCT, however the score itself provides no information on the specific strategy employed. Knowledge of test-taking strategies could have impact on understanding of the actual purpose and benefits of using RCTs in pedagogical and psychological practice. With the ultimate objective of constructing a first standard RCT in Serbian language, the preliminary step we took was to conduct an experimental reading comprehension task (ERCT consisting of 27 short texts displayed in succession, each followed by a single multiplechoice question. Using qualitative analysis of subjects’ responses in semi-structured postexperimental interview, we identified four overall strategies used on ERCT. Our results show that groups of students who used specific strategies differed significantly from one another in text reading time, with no differences found regarding the question reading and answering time. More importantly, there were no significant between-group differences found in terms of ERCT score. These findings suggest that choice of strategy is a way to optimize the relation between one’s own potential and ERCT task requirements. RCT based on ERCT principles would allow for a flexible choice of strategy which would not influence the final score.

  15. Corporate Strategy an Evolutionary Review

    Science.gov (United States)

    Fellman, Philip V.

    As Richard Rumelt indicates in his book, "Fundamental Issues in Strategy: A Research Agenda", corporate strategy is a relatively recent discipline. While pioneers in the field like B.H. Liddell Hart and Bruce Henderson (later to found the Boston Consulting Group and creator of the famous BCG Growth-Share Matrix) began their research during the Second World War, the modern field of business strategy as an academic discipline, taught in schools and colleges of business emerged rather later. Rumelt provides an interesting chronicle in the introduction to his volume by noting that historically corporate strategy, even when taught as a capstone course, was not really an organized discipline. Typically, depending on the school's location and resources, the course would either be taught by the senior most professor in the department or by an outside lecturer from industry. The agenda tended to be very much instructor specific and idiosyncratic rather than drawing in any systematized fashion upon the subject matter of an organized discipline.

    Postural control strategy and balance performance of rugby players are important yet under-examined issues. This study aimed to examine the differences in balance strategy and balance performance between amateur rugby players and non-players, and to explore training- and injury-related factors that may affect rugby players' balance outcomes. Cross-sectional and exploratory study. Forty-five amateur rugby players and 41 healthy active individuals participated in the study. Balance performance and balance strategies were assessed using the sensory organization test (SOT) of the Smart Equitest computerized dynamic posturography machine. Rugby training history and injury history were solicited from the participants. The SOT strategy scores were 1.99-54.90% lower in the rugby group than in the control group (prugby group than in the control group (prugby training (in years) was independently associated with the SOT condition 6 strategy score, explaining 15.7% of its variance (p=0.006). There was no association between SOT condition 6 strategy/equilibrium scores and injury history among the rugby players (p>0.05). Amateur rugby players demonstrated inferior balance strategy and balance performance compared to their non-training counterparts. Their suboptimal balance strategy was associated with insufficient training experience but not with history of injury. Copyright © 2016 Sports Medicine Australia. Published by Elsevier Ltd.

    The aim of the study was to compare the diagnostic yield and the costs of implantable loop recorder (ILR) with those of the conventional strategy in patients with unexplained palpitations. In patients with unexplained palpitations, especially in those with infrequent symptoms, the conventional strategy, including short-term ambulatory electrocardiogram (ECG) monitoring and electrophysiological study, sometimes fails to establish a diagnosis. We studied 50 patients with infrequent (1 min) palpitations. Before enrollment, patients had a negative initial evaluation, including history, physical examination, and ECG. Patients were randomized either to conventional strategy (24-h Holter recording, a 4-week period of ambulatory ECG monitoring with an external recorder, and electrophysiological study) (n = 24) or to ILR implantation with 1-year monitoring (n = 26). Hospital costs of the 2 strategies were calculated. A diagnosis was obtained in 5 patients in the conventional strategy group, and in 19 subjects in the ILR group (21% vs. 73%, p < 0.001). Despite the higher initial cost, the cost per diagnosis in the ILR group was lower than in the conventional strategy group (euro 3,056 +/- euro 363 vs. euro 6,768 +/- euro 6,672, p = 0.012). In subjects without severe heart disease and with infrequent palpitations, ILR is a safe and more cost-effective diagnostic approach than conventional strategy.

    Full Text Available Considering the overall tendency of foreign language learners to use mechanical strategies of rote rehearsal in vocabulary learning and their resistance towards use of 'deep' vocabulary learning strategies, namely contextual guessing, Keyword Method, metacognitive strategy, and semantic mapping, this study intended (a to explore what impact the instruction of these deep strategies, on vocabulary retention of 32 post-intermediate adult EFL Iranian learners, (b to determine how the variable of gender influences the vocabulary retention of students after receiving training in these strategies. To this end, on the basis of a strategy-based model of instruction–CALLA (Chamot & O'Malley, 1994, the experimental group received training in using 'deep' vocabulary learning strategies while the control group received only the common method of vocabulary teaching. After the treatment, following factorial design, the performance of the participants in the teacher-made vocabulary test as posttest was analyzed statistically.  The results indicated higher vocabulary retention for the experimental group, and it was revealed that female students were more receptive to strategy training. This study provides evidence for confirmation of 'depth of processing' hypothesis and the emerging theory about the impact of gender on effective strategy teaching and use, and it recommends incorporation of teaching these 'deep' strategies of vocabulary learning into EFL classrooms.

  1. Evaluation of road-transit physical protection systems

    1978-05-01

    To assess the overall effectiveness of a transportation physical protection system, computer codes which simulate armed attacks have been developed and are being used to examine a range of issues associated with road transportation systems. The paper discusses the purpose and features of three of these codes, SOURCE (which simulates the initial ambush), SABRES I (which covers the battle) and BARS (which treats the penetration of protective cargo barriers). The use of these methodologies to evaluate the value of additional vehicles, guards, armor and alternative tactics or equipment as a means of improving convoy security has recently been completed. The results which are presented demonstrate that the protection offered by the present commercial regulations for guards and vehicles is probably marginal. This could be substantially increased by the addition of armor to close escort vehicles instead of just the transporter and the use of appropriate tactics. Against the baseline threat of adversaries armed with M-16's, observation and harassment from a modest distance until re-enforcements arrive appears preferable to aggressive assault by the ambushed guard force

    Full Text Available BackgroundReconstruction of combined orbital floor and medial wall fractures with a comminuted inferomedial strut (IMS is challenging and requires careful practice. We present our surgical strategy and postoperative outcomes.MethodsWe divided 74 patients who underwent the reconstruction of the orbital floor and medial wall concomitantly into a comminuted IMS group (41 patients and non-comminuted IMS group (33 patients. In the comminuted IMS group, we first reconstructed the floor stably and then the medial wall by using separate implant pieces. In the non-comminuted IMS group, we reconstructed the floor and the medial wall with a single large implant.ResultsIn the follow-up of 6 to 65 months, most patients with diplopia improved in the first-week except one, who eventually improved at 1 year. All patients with an EOM limitation improved during the first month of follow-up. Enophthalmos (displacement, 2 mm was observed in two patients. The orbit volume measured on the CT scans was statistically significantly restored in both groups. No complications related to the surgery were observed.ConclusionsWe recommend the reconstruction of orbit walls in the comminuted IMS group by using the following surgical strategy: usage of multiple pieces of rigid implants instead of one large implant, sequential repair first of the floor and then of the medial wall, and a focus on the reconstruction of key areas. Our strategy of step-by-step reconstruction has the benefits of easy repair, less surgical trauma, and minimal stress to the surgeon.

    2017-11-01

    To examine process factors that either facilitate or inhibit learning medical ethics during case-based learning. A qualitative research approach using microanalysis of transcribed videotaped discussions of three consecutive small-group learning (SGL) sessions on medical ethics teaching (MET) for three groups, each with 10 students. This research effort revealed 12 themes of learning strategies, divided into 6 coping and 6 evasive strategies. Cognitive-based strategies were found to relate to Kamin's model of critical thinking in medical education, thereby supporting our distinction between the themes of coping and evasive strategies. The findings also showed that cognitive efforts as well as emotional strategies are involved in discussions of ethical dilemmas. Based on Kamin's model and the constructivist learning theory, an examination of the different themes within the two learning strategies-coping and evasive-revealed that these strategies may be understood as corresponding to process factors either facilitating or inhibiting MET in SGL, respectively. Our classification offers a more nuanced observation, specifically geared to pinpointing the desired and less desired process factors in the learning involved in MET in the SGL environment. Two key advantages of this observation are: (1) it brings to the forefront process factors that may inhibit and not merely facilitate MET in SGL and (2) it acknowledges the existence of emotional and not just cognitive process factors. Further enhancement of MET in SGL may thus be achieved based on these observations. Published by the BMJ Publishing Group Limited.

    Children of psychiatrically ill parents have a high risk themselves to develop a psychiatric illness in adulthood. Prevention aims at strengthening the resilience of these children and reducing psychosocial risk factors. This article found and describes a theoretical concept of prevention groups for children in schoolage (7-16 years) whose parents are psychiatrically ill. First practical experiences are depicted. The Hamburgian model of prevention works with closed and temporary limited groups of children as well as with the parents. It is based on supporting the children's existing coping strategies and the children are encouraged to exchange their individual experiences of the relationships within their families. One conclusion was, that the main thematic emphasis varied considerably depending on the age of the children.

    This study examined parents' behaviours as they waited with their child. Children were presented with an attractively wrapped gift and then asked not to touch it until the experimenter returned from finishing some work in another room. Three parent groups and their children participated in the study - parents of children with Down syndrome, parents of children with intellectual disability from another cause, and parents of children who were developing typically. There were no significant differences between children in how long they were able to wait before touching the gift. The data from the first two groups were combined for all analyses after it was established that there were no significant differences between them. There were few significant differences between parents of a child with intellectual disability and comparison parents. The former group were more likely to be classified as Authoritarian than were comparison parents, however with one exception, parenting style was unrelated to the strategies parents used in the waiting situation. Very few parents in either group used the opportunity to teach or explicitly praise effective waiting strategies in their children.

    2018-06-01

    The purpose of the study was to compare virtual microscopy with light microscopy to determine differences in learning outcomes and learner attitudes in teaching clinical microscopy to physician assistant (PA) students. A prospective, randomized, crossover design study was conducted with a convenience sample of 67 first-year PA students randomized to 2 groups. One group used light microscopes to find microscopic structures, whereas the other group used instructor-directed video streaming of microscopic elements. At the midpoint of the study, the groups switched instructional strategies. Learning outcomes were assessed via posttest after each section of the study, with comparison of final practical examination results to previous cohorts. Attitudes about the 2 educational strategies were assessed through a postcourse questionnaire with a Likert scale. Analysis of the first posttest demonstrated that students in the video-streamed group had significantly better learning outcomes than those in the light microscopy group (P = .004; Cohen's d = 0.74). Analysis of the posttest after crossover showed no differences between the 2 groups (P = .48). Between the 2 posttests, students first assigned to the light microscopy group scored a 6.6 mean point increase (±10.4 SD; p = .0011), whereas students first assigned to the virtual microscopy group scored a 1.3 mean point increase (±7.1 SD; p = .29). The light microscopy group improved more than the virtual microscopy group (P = .019). Analysis of practical examination data revealed higher scores for the study group compared with 5 previous cohorts of first-year students (P virtual microscopy to traditional light microscopy. Virtual microscopy is an effective educational strategy, and students prefer this method when learning to interpret images of clinical specimens.

    Males outperform females on some spatial tasks, and this may be partially due to the effects of sex steroids on spatial strategy preferences. Previous work with rodents indicates that low estradiol levels bias females toward a striatum-dependent response strategy, whereas high estradiol levels bias them toward a hippocampus-dependent place strategy. We tested whether testosterone influenced the strategy preferences in male rats. All subjects were castrated and assigned to one of three daily injection doses of testosterone (0.125, 0.250, or 0.500 mg/rat) or a control group that received daily injections of the drug vehicle. Three different maze protocols were used to determine rats' strategy preferences. A low dose of testosterone (0.125 mg) biased males toward a motor-response strategy on a T-maze task. In a water maze task in which the platform itself could be used intermittently as a visual cue, a low testosterone dose (0.125 mg) caused a significant increase in the use of a cued-response strategy relative to control males. Results from this second experiment also indicated that males receiving a high dose of testosterone (0.500 mg) were biased toward a place strategy. A third experiment indicated that testosterone dose did not have a strong influence on the ability of rats to use a nearby visual cue (floating ball) in the water maze. For this experiment, all groups seemed to use a combination of place and cued-response strategies. Overall, the results indicate that the effects of testosterone on spatial strategy preference are dose dependent and task dependent. Copyright © 2013 Elsevier Inc. All rights reserved.

A total of 70 EFL university undergraduates (53 females and 17 males took part in the main phase of this study. They were divided into three proficiency groups: high, intermediate, and low. A set of Chi-square analyses was used to explore the type and frequency of test-taking strategies used by participants. The results suggested that the intermediate group test takers used the strategies significantly different after completing each task (sub-test in the FCE reading paper. However, the high and low proficient test takers› use of strategies was only significant after completing the third task of the FCE reading paper. The findings also revealed that a pattern could be drawn of the type of strategies used by the three proficiency groups who participated in this study. Nonetheless, such a pattern shifted at times depending on the ability of the test takers and/or the task under study.

    Kunte, A.; Ringer, W.

    2015-01-01

    On behalf of the Federal Ministry of Agriculture, Forestry, Environment and Water Management (BMLFUW), the National Radon Centre of Austria developed the National Radon Risk Communication Strategy. The superior goal is the reduction of the radon exposure of Austrian citizens as well as the reduction of radon-related lung cancer deaths. Austria, like many other countries, follows the approach to raise awareness and to inform the public to achieve this goal. The presented strategy deals with the question of how radon protection issues can be communicated to the public, existing fears can be reduced and affected people can be motivated to take action (perform a radon test, if necessary, mitigate or install preventive measures in new buildings). The cornerstones of the National Radon Risk Communication Strategy can be summarized as follows: - Definition of communication goals - Identification and categorization of target groups - Development of specific key messages for each of the target groups - Determination of communication channels and assessment of their efficiency - Integration of the radon issue in education and training - Cooperation with relevant organizations and platforms. The communication objectives, target groups and communication paths (and their evaluation) will be discussed during the presentation in detail.

    Past research on emotion regulation strategies has concluded that older adults use more passive strategies than young adults. However, we found scarce research in this field focusing on the oldest old (i.e. those aged 85 and over). The aim of this study was to analyze whether or not differences exist in the way older adults aged 85 and over (centenarians included) use emotion regulation strategies, in comparison with younger age groups (65-74 and 75-84 years old). Participants were 257 older adults from Spain, all aged between 65 and 104. The sample was divided into four age groups: 65-74; 75-84; 85-94; and 95-104 years old. Participants completed the Strategy Questionnaire after reading each of the vignettes designed to elicit feelings of either sadness or anger. The questionnaire measures four types of regulation strategies: Passive, Express, Solve and Seek. The 85-94 age group and centenarians were found to use proactive (Express, Seek) and Solve strategies less in comparison with younger age groups when regulating sadness and anger. In contrast, an increased use of Passive strategies was observed in the regulation of both emotions in the 85-94 age group. Significant differences were also found between centenarians and younger age groups in the use of Passive strategies for sadness, although not for anger. Age differences were observed in the use of emotion regulation strategies, with older age groups using proactive strategies less and passive strategies more.

    Despite the fundamental role of category learning in cognition, few studies have examined how this ability differs between younger and older adults. The present experiment examined possible age differences in category learning strategies and their effects on learning. Participants were trained on a category determined by a disjunctive rule applied to relational features. The utilization of rule- and exemplar-based strategies was indexed by self-reports and transfer performance. Based on self-reported strategies, the frequencies of rule- and exemplar-based learners were not significantly different between age groups, but there was a significantly higher frequency of intermediate learners (i.e., learners not identifying with a reliance on either rule- or exemplar-based strategies) in the older than younger adult group. Training performance was higher for younger than older adults regardless of the strategy utilized, showing that older adults were impaired in their ability to learn the correct rule or to remember exemplar-label associations. Transfer performance converged with strategy reports in showing higher fidelity category representations for younger adults. Younger adults with high working memory capacity were more likely to use an exemplar-based strategy, and older adults with high working memory capacity showed better training performance. Age groups did not differ in their self-reported memory beliefs, and these beliefs did not predict training strategies or performance. Overall, the present results contradict earlier findings that older adults prefer rule- to exemplar-based learning strategies, presumably to compensate for memory deficits.

    1983-09-01

    Survival strategies for hospitals and hospital pharmacy departments are presented, and one hospital's development into a health-services system is described. Financial and competitive pressures are forcing institutions to develop new strategies for survival. The primary institutional strategy is diversification--both horizontal and vertical. Diversification can assist in the hospital's growth, increase its asset and revenue bases, and lead to the development of a health-care delivery system. Marketing to physicians and developing information systems are also critical strategies under a prospective payment system. Institutions will need to know the cost of providing care for specific diagnosis-related groups. Strategies must be employed to develop incentives to reduce inpatient acute-care services and to increase productivity. Physicians should be involved in all of the institutional strategies. Strategies for the pharmacy department are basically the same. Pharmacy departments should develop programs to reduce drug use (especially antibiotic use) and information systems that show the actual cost of providing services by diagnosis. The major corporate restructuring and diversification efforts of one hospital are described. The future of hospitals and pharmacy departments will depend on the successful application of the strategies discussed.

    The hand hygiene (HH) is one of the preventive practices more .widely and effectively implemented in the control of healthcare associated infections. However, there are several barriers to compliance. To assess which strategy, state-of-the-art strategies (availability of alcohol-based preparations, posters, instructions and training) or extended strategies (feedbacks, formal and informal leadership), are seen as more effective to improve hand hygiene (HH) compliance. Analytical study using a self-completed questionnaire developed by the World Health Organization. 2,068 questionnaires, completed by healthcare professionals (HP) in Andalusia (Spain), were received from 2010 to 2012. Analytical technique: Structural equation modeling and multi group measurement invariance. Once the reliability of the proposed constructs was achieved (Cronbach α=0.73, 0.84, 0.70), it was found that those HP working in centers with the highest level of commitment with HH are those who see extended strategies as more effective (χ2=298.3, df=39, CFI=0.972, TLI=0.961, RMSEA=0.057, SRMR=0.028). Our results have shown that hospitals' HP, compared to primary care HP, see state-of-the-art strategies as more effective, as well as they give less importance to HH, meanwhile nurses, compared to physicians, see effective both strategies. HP contemplate the combination of state-of-the-art and extended strategies as an effective way to improve the HH compliance. In addition, extended strategies are considered more effective amongst the most "advanced" healthcare settings in terms of their commitment to HH. The results highlight the need for commitment at management, collective and individual level in order to maintain patient safety.

    Full Text Available The Global Biodiversity Information Facility (GBIF has a mandate to facilitate free and open access to primary biodiversity data worldwide. This Special Issue of Biodiversity Informatics publishes the findings of the recent GBIF Task Group on a Global Strategy and Action Plan for Mobilisation of Natural History Collections Data (GSAP-NHC. The GSAP-NHC Task Group has made three primary recommendations dealing with discovery, capture, and publishing of natural history collections data. This overview article provides insight on various activities initiated by GBIF to date to assist with an early uptake and implementation of these recommendations. It calls for proactive participation by all relevant players and stakeholder communities. Given recent technological progress and growing recognition and attention to biodiversity science worldwide, we think rapid progress in discovery, publishing and access to large volumes of useful collection data can be achieved for the immediate benefit of science and society.

    Humans everywhere cooperate in groups to achieve benefits not attainable by individuals. Individual effort is often not automatically tied to a proportionate share of group benefits. This decoupling allows for free-riding, a strategy that (absent countermeasures) outcompetes cooperation. Empirically and formally, punishment potentially solves the evolutionary puzzle of group cooperation. Nevertheless, standard analyses appear to show that punishment alone is insufficient, because second-order free riders (those who cooperate but do not punish) can be shown to outcompete punishers. Consequently, many have concluded that other processes, such as cultural or genetic group selection, are required. Here, we present a series of agent-based simulations that show that group cooperation sustained by punishment easily evolves by individual selection when you introduce into standard models more biologically plausible assumptions about the social ecology and psychology of ancestral humans. We relax three unrealistic assumptions of past models. First, past models assume all punishers must punish every act of free riding in their group. We instead allow punishment to be probabilistic, meaning punishers can evolve to only punish some free riders some of the time. This drastically lowers the cost of punishment as group size increases. Second, most models unrealistically do not allow punishment to recruit labor; punishment merely reduces the punished agent's fitness. We instead realistically allow punished free riders to cooperate in the future to avoid punishment. Third, past models usually restrict agents to interact in a single group their entire lives. We instead introduce realistic social ecologies in which agents participate in multiple, partially overlapping groups. Because of this, punitive tendencies are more expressed and therefore more exposed to natural selection. These three moves toward greater model realism reveal that punishment and cooperation easily evolve by

    To identify the general public's perceptions of the overall risk communication strategy carried out by Chinese public health agencies during the first wave of avian influenza A(H7N9) outbreak in humans in 2013. Participants were recruited from communities in Beijing, Lanzhou and Hangzhou, China in May and June 2013 by convenience sampling. Demographics and other relevant information were collected using a self-administered questionnaire. Focus group interviews were conducted using a set of nine pre-developed questions and a tested moderator guide. The interviews were audio recorded and were transcribed verbatim. The constant comparative method was used to identify trends and themes. A total of nine focus group interviews, with 94 participants recruited from nine communities, were conducted. Most participants received H7N9 information via television and the Internet. Most the participants appreciated the transparency and timeliness of the information released by the government. They expressed a sense of trust in the recommended public health advice and followed most of them. The participants suggested that the government release more information about clinical treatment outcomes, have more specific health recommendations that are practical to their settings and expand the use of new media channels for risk communication. The public perceived the overall risk communication strategy by the Chinese public health agencies as effective, though the moderator had a governmental agency title that might have biased the results. There is a need to expand the use of social media for risk communication in the future.

    There is growing recognition of benefits of sophisticated information technology (IT) in nursing homes (NHs). In this research, we explore strategies nursing assistants (NAs) use to communicate pressure ulcer prevention practices in NHs with variable IT sophistication measures. Primary qualitative data were collected during focus groups with NAs in 16 NHs located across Missouri. NAs (n = 213) participated in 31 focus groups. Three major themes referencing communication strategies for pressure ulcer prevention were identified, including Passing on Information, Keeping Track of Needs and Information Access. NAs use a variety of strategies to prioritize care, and strategies are different based on IT sophistication level. NA work is an important part of patient care. However, little information about their work is included in communication, leaving patient records incomplete. NAs' communication is becoming increasingly important in the care of the millions of chronically ill elders in NHs. © The Author(s) 2014.

    2010-05-01

    Full Text Available It is well known that students and teachers have difficulties in learning and teaching Biochemistry due to its abstract and interconnected contents. This work proposes a didactic strategy in order to facilitate teaching and learning process in Biochemistry. The strategy was implemented with biological science undergraduate students. At first, the students were divided into groups with a specific topic to develop a game. During the semester, problem based learning cases, online activities like crossword puzzle, essay questions and educational softwares were used to present the content of each topic. The groups were oriented in classroom and online, to choose and organize contents and create ways to approach them in games. At the end of the course the groups played each other games, which were evaluated by teacher and students following some criteria like: creativity, content organization, interdisciplinarity, proposal coherence, instructions clarity, specific content. The game elaboration contributed to the development of social and cognitive functions, such as teamwork and troubleshooting, providing an interesting perspective to the student about knowledge construction process. The strategy showed up students' creativity and ability to reorganize their knowledge to a different education level. In an overview, the results indicate that the proposed didactic strategy is an effective way to enhance learning and to motivate students into Biochemistry topics.

  16. Strategic Groups and Banks’ Performance

    Full Text Available The theory of strategic groups predicts the existence of stable groups of companies that adopt similar business strategies. The theory also predicts that groups will differ in performance and in their reaction to external shocks. We use cluster analysis to identify strategic groups in the Polish banking sector. We find stable groups in the Polish banking sector constituted after the year 2000 following the major privatisation and ownership changes connected with transition to the mostly-privately-owned banking sector in the late 90s. Using panel regression methods we show that the allocation of banks to groups is statistically significant in explaining the profitability of banks. Thus, breaking down the banks into strategic groups and allowing for the different reaction of the groups to external shocks helps in a more accurate explanation of profits of the banking sector as a whole.Therefore, a more precise ex ante assessment of the loss absorption capabilities of banks is possible, which is crucial for an analysis of banking sector stability. However, we did not find evidence of the usefulness of strategic groups in explaining the quality of bank portfolios as measured by irregular loans over total loans, which is a more direct way to assess risks to financial stability.

    Full Text Available Reading comprehension is one of the most important skills, especially in the EFL context. One way to improve reading comprehension is through strategy use. The present study aimed at investigating the effect of question-generation strategy on learners' reading comprehension. The participants in the study were 63 intermediate students from three intact groups in Resa institute in Boukan, They were randomly assigned to two experimental and one control groups. They were given two samples of the reading section of the standardized Preliminary English Test (PET as the pre- and post-tests. The students in the experimental group A generated text-based reading comprehension questions individually, and in the experimental group B  in groups of three but the learners in the control group answered the reading comprehension questions provided in the text. The results of ANOVA revealed that the students in the experimental group B, who employed group-question generation strategy, outperformed the experimental group A, who employed individual- question generation strategy and the control group in the reading comprehension post-test. The findings can have some implications for EFL teachers and syllabus designers.

    In this paper, we analyze the effectiveness of the Integrated Dynamic Representation strategy (IDR) to develop basic math skills. The study involved 72 students, aged between 6 and 8 years. We compared the development of informal basic skills (numbers, comparison, informal calculation, and informal concepts) and formal (conventionalisms, number facts, formal calculus, and formal concepts) in an experimental group (n = 35) where we applied the IDR strategy and in a Control group (n = 37) in order to identify the impact of the procedure. The experimental group improved significantly in all variables except for number facts and formal calculus. It can therefore be concluded that IDR favors the development of the skills more closely related to applied mathematics than those related to automatic mathematics and mental arithmetic.

Conclusions A number of reviews were systematic and scored highly for methodological quality. These reviews provide a good reflection of the primary evidence and could be used to inform policy. The complexity and inter-relatedness of factors leading to low service use was recognised and reflected in reviews' recommendations for service improvement. Recommendations made in the UK End-of-Life Care Strategy were limited in comparison, and the Strategy's evidence base concerning minority ethnic groups was found to be narrow. Future policy should be embedded strongly in the evidence base to reflect the current literature and minimise bias.

    2008-09-01

    This study investigated social knowledge in school-age children, aged 8-12 years, with and without language impairment (LI and TD groups). A hypothetical peer conflict task was administered to examine the relationship among prosocial responses and parent/teacher ratings of children's social behaviours. Stimuli included 12 hypothetical peer conflict vignettes presented in an open-ended and forced choice condition. The LI group generated (open-ended) and selected (forced choice) fewer prosocial strategies. When asked to predict a friend's reaction to a selected conflict resolution strategy, the LI group predicted fewer positive consequences; however, the proportion of prosocial strategies followed by prediction of a positive peer consequence was similar across groups. Both groups identified more self-interest than relationship goals as the rationale for selected strategies. In the LI group, teacher ratings of children's social skills and problems in peer provocation situations were associated with selection of prosocial strategies. Implications for clinical service providers are discussed.

    Full Text Available The Sahara frog is the most common amphibian found in North Africa. However, the knowledge of its natural history is rather fragmentary. In the present work we studied the trophic ecology of Pelophylax saharicus at some areas of Morocco through the analysis of 130 gastric contents. We did not find any significant sexual dimorphism in body size of adult individuals. Consumed prey show similar sizes in both sexes, while bigger frogs normally eat larger prey. As in other Palearctic frogs, the diet is basically insectivorous, including terrestrial and aquatic prey. We found some differences in the diet of juveniles, with a higher proportion of flying prey, probably indicating a foraging strategy closer to ambush hunting. In the Atlas region, the high consumption of slow-moving terrestrial prey, as Gastropoda, stands out. Only in the Atlas region, the diet was similar to that described from other areas of North Africa, as Tunisia.

    Sandahl, Sheryl S

    2010-01-01

    A primary goal of nursing education is to prepare nurses to work collaboratively as members of interprofessional health care teams on behalf of patients. Collaborative testing is a collaborative learning strategy used to foster knowledge development, critical thinking in decision making, and group processing skills. This study incorporated a quasi-experimental design with a comparison group to examine the effect of collaborative testing as a learning strategy on student learning and retention of course content as well as group process skills and student perceptions of their learning and anxiety. The setting was a baccalaureate nursing program; the sample consisted of two groups of senior students enrolled in Medical-Surgical Nursing II. Student learning, as measured by unit examination scores, was greater for students taking examinations collaboratively compared to individually. Retention of course content, as measured by final examination scores, was not greater for students taking examinations collaboratively compared to individually. Student perceptions were overwhelmingly positive, with students reporting increased learning as a result of the collaborative testing experiences. Despite the lack of data to support increased retention, collaborative testing may be a learning strategy worth implementing in nursing education. Students reported more positive interactions and collaboration with their peers, skills required by the professional nurse.

  7. Revisiting life strategy concepts in environmental microbial ecology.

    2017-03-01

    Microorganisms are physiologically diverse, possessing disparate genomic features and mechanisms for adaptation (functional traits), which reflect on their associated life strategies and determine at least to some extent their prevalence and distribution in the environment. Unlike animals and plants, there is an unprecedented diversity and intractable metabolic versatility among bacteria, making classification or grouping these microorganisms based on their functional traits as has been done in animal and plant ecology challenging. Nevertheless, based on representative pure cultures, microbial traits distinguishing different life strategies had been proposed, and had been the focus of previous reviews. In the environment, however, the vast majority of naturally occurring microorganisms have yet to be isolated, restricting the association of life strategies to broad phylogenetic groups and/or physiological characteristics. Here, we reviewed the literature to determine how microbial life strategy concepts (i.e. copio- and oligotrophic strategists, and competitor-stress tolerator-ruderals framework) are applied in complex microbial communities. Because of the scarcity of direct empirical evidence elucidating the associated life strategies in complex communities, we rely heavily on observational studies determining the response of microorganisms to (a)biotic cues (e.g. resource availability) to infer microbial life strategies. Although our focus is on the life strategies of bacteria, parallels were drawn from the fungal community. Our literature search showed inconsistency in the community response of proposed copiotrophic- and oligotrophic-associated microorganisms (phyla level) to changing environmental conditions. This suggests that tracking microorganisms at finer phylogenetic and taxonomic resolution (e.g. family level or lower) may be more effective to capture changes in community response and/or that edaphic factors exert a stronger effect in community response

    The Intergovernmental Panel on Climate Change (IPCC) was established in November 1988 under the joint auspices of UNEP and the World Meteorological Organization (WMO). Working Group III, or the Response Strategies Working Group (RSWG), was established to formulate strategies to respond to challenges arising from global climate warming. The Energy and Industry Subgroup (EIS) was created by the RSWG at its meeting in January-February 1989 to facilitate the formulation of strategies to control, i.e. prevent or reduce, the accumulation of greenhouse gases (GHGs) such as CO 2 , CFCs, NO 2 , CH, etc. The following article gives a brief summary of EIS activities, based mainly on records of discussion at the relevant meetings.

    Full Text Available Training students to become independent skillful readers is a major concern of the EFL reading teacher. How can we best train students in selecting and applying reading strategies so that they become more efficient readers? Can we ensure that an increase in students’ awareness of the need to use strategies will help them become more skillful readers? These questions served as a trigger for this study. The aim of this study was to investigate whether verbal articulation of reading behavior in a small group will improve foreign language comprehension. It is our contention that using verbalization in small groups will raise metacognitive awareness which will in turn enhance effective use of skills and strategies and result in improvement in reading comprehension. We assume that the special features that characterize small group interactions can provide an appropriate setting for raising metacognitive awareness.

    2009-06-01

    Full Text Available Collaborative learning in an online classroom can take the form of discussion among the whole class or within smaller groups. This paper addresses the latter, examining first whether assessment makes a difference to the level of learner participation and then considering other factors involved in creating effective collaborative learning groups. Data collected over a three year period (15 cohorts from the Foundations course in the Master of Distance Education (MDE program offered jointly by University of Maryland University College (UMUC and the University of Oldenburg does not support the authors’ original hypothesis that assessment makes a significant difference to learner participation levels in small group learning projects and leads them to question how much emphasis should be placed on grading work completed in study groups to the exclusion of other strategies. Drawing on observations of two MDE courses, including the Foundations course, their extensive online teaching experience, and a review of the literature, the authors identify factors other than grading that contribute positively to the effectiveness of small collaborative learning groups in the online environment. In particular, the paper focuses on specific instructional strategies that facilitate learner participation in small group projects, which result in an enhanced sense of community, increased skill acquisition, and better learning outcomes.

    Academic writing is a challenging task. Expert writers apply various writing skills as they anticipate the reader's view of their text while paying attention to structure and content. Research in the high school setting shows that the acquisition of writing skills can be supported by single-strategy training. However, research in higher education is scarce. We tested whether the development of academic writing skills can also be effectively supported by training single strategies or even combined strategies. As metacognition is an important skill for advanced and adult learners, we focused in this study on the benefit of combined cognitive strategies with and without a metacognitive strategy. An experiment including three conditions was conducted (N = 60 German-speaking psychology undergraduates, M = 22.8, SD = 4.4), which lasted for three hours. Each group received a modeling intervention of a basic cognitive strategy on the application of text structure knowledge. Two groups received an additional modeling intervention with either a cognitive strategy treatment on text summarization or a metacognitive strategy treatment on self-monitoring the writing process. One group received no further strategy treatment. Prior knowledge and learning outcomes were measured with a specially developed test on academic writing skills. In addition, all participants wrote an abstract of an empirical article. We found that learners who received the additional self-monitoring strategy intervention benefited significantly more in terms of acquisition of academic writing skills and the quality of their texts than learners who did not receive this intervention. Thus, the results underline the importance of self-monitoring strategies in academic writing. Implications and further research opportunities are discussed.

    Science.gov (United States)

    1995-01-01

    In 1994, the Clinton Administration issued a report, 'Science in the National Interest', which identified new national science goals. Two of the five goals are related to science communications: produce the finest scientists and engineers for the 21st century, and raise scientific and technological literacy of all Americans. In addition to the guidance and goals set forth by the Administration, NASA has been mandated by Congress under the 1958 Space Act to 'provide for the widest practicable and appropriate dissemination concerning its activities and the results thereof'. In addition to addressing eight Goals and Plans which resulted from a January 1994 meeting between NASA and members of the broader scientific, education, and communications community on the Public Communication of NASA's Science, the Science Communications Working Group (SCWG) took a comprehensive look at the way the Agency communicates its science to ensure that any changes the Agency made were long-term improvements. The SCWG developed a Science Communications Strategy for NASA and a plan to implement the Strategy. This report outlines a strategy from which effective science communications programs can be developed and implemented across the agency. Guiding principles and strategic themes for the strategy are provided, with numerous recommendations for improvement discussed within the respective themes of leadership, coordination, integration, participation, leveraging, and evaluation.

    The best surgical strategy for the management of perforated diverticulitis with generalized peritonitis of the sigmoid colon is not clearly defined. The aim of this retrospective cohort study was to evaluate the value of a damage control strategy. All patients who underwent emergency laparotomy for perforated diverticular disease of the sigmoid colon with generalized peritonitis between 2010 and 2015 were included. The damage control strategy (study group), included a two- stage procedure: limited resection of the diseased colonic segment, closure of proximal colon and distal stump, and application of an abdominal vacuum at the initial surgery followed by second-look laparotomy 24-48 h later At this point a choice was made between anastomosis and Hartmann's procedure. The control group consisted of patients receiving definitive reconstruction (anastomosis or Hartmann's procedure) at the initial operation. Thirty-seven patients were included in the study. Damage control strategy was applied in 19 patients and the control group consisted of 18 patients. Both groups were comparable in terms of demographics, severity of peritonitis, and comorbidities. The overall postoperative mortality was 11 % (n = 4). There were no statistically significant differences between both groups regarding postoperative morbidity and mortality; however, a significantly higher proportion of patients in the control group had a stoma after the initial hospital stay (83 vs. 47 %, p = 0.038). This difference was still significant after adjustment for sex, age, Mannheim Peritonitis Index, American Society of Anesthesiologists class and presence of septic shock at presentation. At the end of the follow-up period, 15 of 17 survivors in the study group and 13 of 16 survivors in the control group had their intestinal continuity restored (p = 0.66). Damage control strategy in patients with generalized peritonitis due to perforated diverticulitis leads to a significantly reduced stoma rate

    2012-07-01

    Previous research has demonstrated that trainees can be taught (via explicit verbal instruction) to adopt the gaze strategies of expert laparoscopic surgeons. The current study examined a software template designed to guide trainees to adopt expert gaze control strategies passively, without being provided with explicit instructions. We examined 27 novices (who had no laparoscopic training) performing 50 learning trials of a laparoscopic training task in either a discovery-learning (DL) group or a gaze-training (GT) group while wearing an eye tracker to assess gaze control. The GT group performed trials using a surgery-training template (STT); software that is designed to guide expert-like gaze strategies by highlighting the key locations on the monitor screen. The DL group had a normal, unrestricted view of the scene on the monitor screen. Both groups then took part in a nondelayed retention test (to assess learning) and a stress test (under social evaluative threat) with a normal view of the scene. The STT was successful in guiding the GT group to adopt an expert-like gaze strategy (displaying more target-locking fixations). Adopting expert gaze strategies led to an improvement in performance for the GT group, which outperformed the DL group in both retention and stress tests (faster completion time and fewer errors). The STT is a practical and cost-effective training interface that automatically promotes an optimal gaze strategy. Trainees who are trained to adopt the efficient target-locking gaze strategy of experts gain a performance advantage over trainees left to discover their own strategies for task completion.

    The transition from paediatric to adult care is associated with poor clinical outcomes, increased costs and low patient and family satisfaction. However, little is known about health system strategies to streamline and safeguard care for youth transitioning to adult services. Moreover, the needs of children and youth are often excluded from broader health system reform discussions, leaving this population especially vulnerable to system 'disintegration'. (1) To explore the international policy profile of paediatric-to-adult care transitions, and (2) to document policy objectives, initiatives and outcomes for jurisdictions publicly committed to addressing transition issues. An international policy scoping review of all publicly available government documents detailing transition-related strategies was completed using a web-based search. Our analysis included a comparable cohort of nine wealthy Organisation for Economic Co-operation and Development (OECD) jurisdictions with Beveridge-style healthcare systems (deemed those most likely to benefit from system-level transition strategies). Few jurisdictions address transition of care issues in either health or broader social policy documents. While many jurisdictions refer to standardised practice guidelines, a few report the intention to use powerful policy levers (including physician remuneration and non-physician investments) to facilitate the uptake of best practice. Most jurisdictions do not address the policy infrastructure required to support successful transitions, and rigorous evaluations of transition strategies are rare. Despite the well-documented risks and costs associated with a poor transition from paediatric to adult care, little policy attention has been paid to this issue. We recommend that healthcare providers engage health system planners in the design and evaluation of system-level, policy-sensitive transition strategies.

  13. Strategy intervention for the evolution of fairness.

    Directory of Open Access Journals (Sweden)

    Yanling Zhang

    Full Text Available The 'irrational' preference for fairness has attracted increasing attention. Although previous studies have focused on the effects of spitefulness on the evolution of fairness, they did not consider non-monotonic rejections shown in behavioral experiments. In this paper, we introduce a non-monotonic rejection in an evolutionary model of the Ultimatum Game. We propose strategy intervention to study the evolution of fairness in general structured populations. By sequentially adding five strategies into the competition between a fair strategy and a selfish strategy, we arrive at the following conclusions. First, the evolution of fairness is inhibited by altruism, but it is promoted by spitefulness. Second, the non-monotonic rejection helps fairness overcome selfishness. Particularly for group-structured populations, we analytically investigate how fairness, selfishness, altruism, and spitefulness are affected by population size, mutation, and migration in the competition among seven strategies. Our results may provide important insights into understanding the evolutionary origin of fairness.

  15. Group size, grooming and fission in primates: a modeling approach based on group structure.

    Science.gov (United States)

    Sueur, Cédric; Deneubourg, Jean-Louis; Petit, Odile; Couzin, Iain D

    2011-03-21

    In social animals, fission is a common mode of group proliferation and dispersion and may be affected by genetic or other social factors. Sociality implies preserving relationships between group members. An increase in group size and/or in competition for food within the group can result in decrease certain social interactions between members, and the group may split irreversibly as a consequence. One individual may try to maintain bonds with a maximum of group members in order to keep group cohesion, i.e. proximity and stable relationships. However, this strategy needs time and time is often limited. In addition, previous studies have shown that whatever the group size, an individual interacts only with certain grooming partners. There, we develop a computational model to assess how dynamics of group cohesion are related to group size and to the structure of grooming relationships. Groups' sizes after simulated fission are compared to observed sizes of 40 groups of primates. Results showed that the relationship between grooming time and group size is dependent on how each individual attributes grooming time to its social partners, i.e. grooming a few number of preferred partners or grooming equally or not all partners. The number of partners seemed to be more important for the group cohesion than the grooming time itself. This structural constraint has important consequences on group sociality, as it gives the possibility of competition for grooming partners, attraction for high-ranking individuals as found in primates' groups. It could, however, also have implications when considering the cognitive capacities of primates. Copyright © 2010 Elsevier Ltd. All rights reserved.

    A central theme in the strategic groups literature is that there is a theoretical relationship between groups and firm performance. However, the empirical evidence is conflicting. The aim of this research is to study this linkage through two analysis. Thus, the analysis that has been traditionally used (performance differences between groups) is complemented with an analysis of performance differences within each group. In order to set up strategic groups, we carry out an analysis about the...

    A new collaborative filtered recommendation strategy was proposed for existing privacy and security issues in location services. In this strategy, every user establishes his/her own position profiles according to their daily position data, which is preprocessed using a density clustering method. Then, density prioritization was used to choose similar user groups as service request responders and the neighboring users in the chosen groups recommended appropriate location services using a collaborative filter recommendation algorithm. The two filter algorithms based on position profile similarity and position point similarity measures were designed in the recommendation, respectively. At the same time, the homomorphic encryption method was used to transfer location data for effective protection of privacy and security. A real location dataset was applied to test the proposed strategy and the results showed that the strategy provides better location service and protects users’ privacy. PMID:29751670

    While formative workplace based assessment can improve learners' skills, it often does not because the procedures used do not facilitate feedback which is sufficiently specific to scaffold improvement. Provision of pre-formulated strategies to address predicted learning needs has potential to improve the quality and automate the provision of written feedback. To systematically develop, validate and maximise the utility of a comprehensive list of strategies for improvement of consultation skills through a process involving both medical students and their clinical primary and secondary care tutors. Modified Delphi study with tutors, modified nominal group study with students with moderation of outputs by consensus round table discussion by the authors. 35 hospital and 21 GP tutors participated in the Delphi study and contributed 153 new or modified strategies. After review of these and the 205 original strategies, 265 strategies entered the nominal group study to which 46 year four and five students contributed, resulting in the final list of 249 validated strategies. We have developed a valid and comprehensive set of strategies which are considered useful by medical students. This list can be immediately applied by any school which uses the Calgary Cambridge Framework to inform the content of formative feedback on consultation skills. We consider that the list could also be mapped to alternative skills frameworks and so be utilised by schools which do not use the Calgary Cambridge Framework.

     The aim of this study was to assess methods used to access target groups in prevention projects funded within the prevention research framework by the German Federal Ministry of Education and Research.  A survey with prevention projects was conducted. Access strategies, communication channels, incentives, programme reach, and successful practical recruitment strategies were explored.  38 out of 60 projects took part in the survey. Most projects accessed their target group within structured settings (e. g., child day-care centers, schools, workplaces). Multiple communication channels and incentives were used, with written information and monetary incentives being used most frequently. Only few projects were able to report their programme reach adequately; programme reach was highest for programmes accessing the target groups in structured settings. The respondents viewed active recruitment via personal communication with the target group and key persons in the settings as the most successful strategy.  The paper provides an overview on recruitment strategies used in current preven-tion projects. More systematic research on programme reach is necessary. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available This study investigated the influence of Pre-question and genre-based instructional strategies on science undergraduates’ achievement in, and attitude to, reading. Using purposive sampling,two specialised universities in Nigeria were selected and stratified sampling was employed in assigning students to research groups based on gender and performance in a verbal ability test. Two hundred and eighty-five students participated in the study. Pre-post randomised block experimental design was used with three experimental groups and one control group. The experimental procedure involving Pre-question, genre-based instruction and a combination of Pre-question and genre-based instructional strategies were used for the experimental groups for four weeks whilst the control group received normal teacher input. Data were collected through a Reading Comprehension Achievement Test and Students’ Attitude Questionnaire. Qualitative data, obtained from videotapes of classroom interactions, were subjected to conversation and interaction analyses and quantitative data were analysed with Analysis of Covariance (ANCOVA. The results indicate that although there was no significant main effect of instructional strategy on students’ achievement in reading comprehension, there was significant main effect of instructional strategy on students’ attitude to reading (F(3,231 = 30.9;p <.05. Findings from the qualitative enquiry revealed that female students were more voluble and assertive in their responses probably because of the need to resist male domination whilst male students used discourse strategies to affirm their authority. The study indicated that the combination of pre-question and genre-based approach was the most effective in enhancing the students’ attitude to reading. Reading is one of the most useful of the Language Arts skills which learners need for academic reasons and for lifelong learning. The globalised world demands that the second language

  6. Cognitive dissonance in groups: the consequences of disagreement.

    Matz, David C; Wood, Wendy

    2005-01-01

    As L. Festinger (1957) argued, the social group is a source of cognitive dissonance as well as a vehicle for reducing it. That is, disagreement from others in a group generates dissonance, and subsequent movement toward group consensus reduces this negative tension. The authors conducted 3 studies to demonstrate group-induced dissonance. In the first, students in a group with others who ostensibly disagreed with them experienced greater dissonance discomfort than those in a group with others who agreed. Study 2 demonstrated that standard moderators of dissonance in past research--lack of choice and opportunity to self-affirm, similarly reduced dissonance discomfort generated by group disagreement. In Study 3, the dissonance induced by group disagreement was reduced through a variety of interpersonal strategies to achieve consensus, including persuading others, changing one's own position, and joining an attitudinally congenial group.

    This study aimed to implement innovative teaching methods--blended learning strategies--that include the use of new information technologies in the teaching of human anatomy and to analyse both the impact of these strategies on academic performance, and the degree of user satisfaction. The study was carried out among students in Year 1 of the biology degree curriculum (human biology profile) at Pompeu Fabra University, Barcelona. Two groups of students were tested on knowledge of the anatomy of the locomotor system and results compared between groups. Blended learning strategies were employed in 1 group (BL group, n = 69); the other (TT group; n = 65) received traditional teaching aided by complementary material that could be accessed on the Internet. Both groups were evaluated using the same types of examination. The average marks presented statistically significant differences (BL 6.3 versus TT 5.0; P < 0.0001). The percentage pass rate for the subject in the first call was higher in the BL group (87.9% versus 71.4%; P = 0.02), reflecting a lower incidence of students who failed to sit the examination (BL 4.3% versus TT 13.8%; P = 0.05). There were no differences regarding overall satisfaction with the teaching received. Blended learning was more effective than traditional teaching for teaching human anatomy.

    Full Text Available Many studies have been conducted to explore language learning strategies (Rubin, 1975, Naiman et . al ., 1978; Fillmore, 1979; O'Malley et . al ., 1985 and 1990; Politzer and Groarty, 1985; Prokop, 1989; Oxford, 1990; and Wenden, 1991. In the current study a total of 79 university students participating in a 3 month English course participated. This study attempted to explore what language learning strategies successful learners used and to what extent the strategies contributed to success in learning English in Indonesia . Factor analyses, accounting for 62.1 %, 56.0 %, 41.1 %, and 43.5 % of the varience of speaking, listening, reading and writing measures in the language learning strategy questionnaire, suggested that the questionnaire constituted three constructs. The three constructs were named metacognitive strategies, deep level cognitive and surface level cognitive strategies. Regression analyses, performed using scales based on these factors revealed significant main effects for the use of the language learning strategies in learning English, constituting 43 % of the varience in the posttest English achievement scores. An analysis of varience of the gain scores of the highest, middle, and the lowest groups of performers suggested a greater use of metacognitive strategies among successful learners and a greater use of surface level cognitive strategies among unsuccessful learners. Implications for the classroom and future research are also discussed.

    This study investigated the effect of different presentation strategies (2-D static visuals, 3-D animated visuals, and 3-D interactive, animated visuals) and gender on achievement, time-spent-on visual treatment, and attitude during a computer-based science lesson about reading and interpreting topographic maps. The study also examined the relationship of spatial ability and prior knowledge to gender, achievement, and time-spent-on visual treatment. Students enrolled in high school chemistry-physics were pretested and given two spatial ability tests. They were blocked by gender and randomly assigned to one of three levels of presentation strategy or the control group. After controlling for the effects of spatial ability and prior knowledge with analysis of covariance, three significant differences were found between the versions: (a) the 2-D static treatment group scored significantly higher on the posttest than the control group; (b) the 3-D animated treatment group scored significantly higher on the posttest than the control group; and (c) the 2-D static treatment group scored significantly higher on the posttest than the 3-D interactive animated treatment group. Furthermore, the 3-D interactive animated treatment group spent significantly more time on the visual screens than the 2-D static treatment group. Analyses of student attitudes revealed that most students felt the landform visuals in the computer-based program helped them learn, but not in a way they would describe as fun. Significant differences in attitude were found by treatment and by gender. In contrast to findings from other studies, no gender differences were found on either of the two spatial tests given in this study. Cognitive load, cognitive involvement, and solution strategy are offered as three key factors that may help explain the results of this study. Implications for instructional design include suggestions about the use of 2-D static, 3-D animated and 3-D interactive animations as well

    Concurrent chemoradiotherapy(CRT) is standard therapy for locally-advanced non-small-cell lung cancer(LA-NSCLC)patients. This study was performed to examine thoracic radiotherapy(TRT) parameters and their impact on patient survival. We collected Individual patient data(IPD) from 3600LA-NSCLC patients participating in 16 cooperative group trials of concurrent CRT. The primary TRT parameters examined included field design strategy(elective nodal irradiation(ENI) compared to involved field TRT(IF-TRT)), total dose, and biologically effective dose(BED). Hazard ratios(HRs) for overall survival were calculated with univariable and multivariable Cox models. TRT doses ranged from 60 to 74 Gy with most treatments administered once-daily. ENI was associated with poorer survival than IF-TRT(univariable HR,1.37;95%CI,1.24-1.51,pENI patients were 24 and 16 months, respectively. Patients were divided into 3 dose groups: low total dose(60 Gy), medium total dose(>60Gy-66Gy) and high total dose(>66Gy-74 Gy). With reference to the low dose group, the multivariable HR's were 1.08 for the medium dose group(95%CI=0.93-1.25) and 1.12 for the high dose group(CI=0.97-1.30).The univariate p=0.054 and multivariable p=0.17. BED was grouped as follows: low(55.5 Gy 10 ). With reference to the low BED group, the HR was 1.00(95%CI=0.85-1.18) for the medium BED group and 1.10(95%CI=0.93-1.31) for the high BED group. The univariable p=0.076 and multivariable p=0.16. For LA-NSCLC patients treated with concurrent CRT, IF-TRT was associated with significantly better survival than ENI-TRT. TRT total and BED dose levels were not significantly associated with patient survival. Future progress will require research focusing on better systemic therapy and TRT. Copyright © 2018.

  18. A strategy to encourage housing associations to invest in energy conservation

    International Nuclear Information System (INIS)

    Egmond, C.; Jonkers, R.; Kok, G.

    2005-01-01

    To meet the Dutch Government goal of reducing CO 2 emission, target groups must intensify their efforts to conserve energy. Novem, in commission of the Dutch Ministry of Environmental Affairs, developed a strategy to effectively change the behaviour of target groups. This paper answers the questions: what are the influencing determinants of energy-relevant behaviour of housing associations; and which policy instruments are most suitable for an intervention strategy? From a survey of housing associations we determined the factors making up the determinants of behaviour. The four main types of policy instruments-judicial, economical and communicative instruments and physical provisions-were analysed for their active ingredients. An intervention strategy was then based on matching the factors making up the target-group determinants and the active ingredients of the policy instruments. The factors: attitude, feedback of peer organizations and feedback from authorities strongly influence the energy-relevant behaviour of housing associations and the most effective policy instruments have a facilitating and encouraging character and include covenants with local authorities. We conclude that this method forms a solid basis for formulating an intervention strategy to change the behaviour of housing associations

    Full Text Available The aim of this study is to examine the impact of metacognitive listening strategy instruction on the listening sub-skills performance of the Iranian pre-intermediate EFL learners at the Foreign Language Center, Imam Ali University. The current study has been conducted with 64 participants. They were assigned into two groups randomly, an experimental group (n: 32 and a control group (n: 32. To determine the listening comprehension ability of the participants, a listening comprehension pretest based on the listening sub-skills was administered to the participants before the experiment. Then, the experimental group received an eight-week treatment on metacognitive listening strategies. After the treatment phase, a posttest was given to the participants in both the experimental and control group. The results of the independent t-test showed that there is a statistically significant difference (3.29>2; df = 62 between the posttest scores of the experimental group and the control group. Metacognitive strategy training promoted students’ listening comprehension remarkably; therefore, it should be integrated into the listening instruction programs to help language learners become more effective listeners.

    Full Text Available The present study reports on an action research study that explores the implications of applying three vocabulary strategies: word cards, association with pictures, and association with a topic through fables in the acquisition of new vocabulary in a group of EFL low-level proficiency teenagers in a public school in Espinal, Tolima, Colombia. The participants had never used vocabulary strategies before and struggled to memorize and recall words.  Two types of questionnaires, a researcher’s journal, and vocabulary tests were the instruments used to gather data.  The results showed that these strategies were effective to expand the range of words progressively and improve the ability to recall them. The study also found that these strategies involve cognitive and affective factors that can affect students’ perception about the strategies and their use. The implementation of the strategies highlighted the need to train teachers and learners in strategies intended to teach and learn vocabulary and to include them in the English language program in any school.
