Effects of UV-B radiation on fitness related behaviors of the sea urchin Strongylocentrotus intermedius

Ozone depletion induced by anthropogenic gases has been increasing the transmission of solar ultraviolet-B radiation(UV-B, 280–315 nm) through the atmosphere, which may impact the fitness of marine invertebrates in intertidal and shallow waters. To our knowledge, however, the responses of fitness related behaviors to UV-B radiation at different intensities have been rarely studied in marine invertebrates. For the first time, the present study investigated the eff ects of exposure of one hour to UV-B radiation at different intensities on foraging behavior, Aristotle's lantern reflex and righting behavior of the sea urchin Strongylocentrotus intermedius. Exposure of one hour to UV-B radiation at 10 μW/cm^2 significantly reduced foraging behavior. An intensity dependent eff ect of exposure to UV-B radiation was found in the duration of the Aristotle's lantern reflex. Exposure to UV-B radiation at 20 μW/cm^2 for one hour significantly reduced the duration of the Aristotle's lantern reflex, but 10 μW/cm^2 did not. There was no significant diff erence of righting response time among sea urchins exposed to 0, 10 and 20 μW/cm^2 for one hour. To test potential carryover ef fects, the behavioral traits were re-measured three days later. We found significant carryover eff ects of UV-B radiation on foraging time and righting response time, but not on the duration of the Aristotle's lantern reflex. The present study indicates that a brief exposure of one hour to UV-B radiation can significantly aff ect the duration of Aristotle's lantern reflex, righting response time and foraging behavior of a sea urchin, although the immediate impacts and carryover eff ects were highly trait dependent. This study provides new information into the behavioral responses of marine invertebrates to exposure to UV-B radiation. Future studies should be carried out to investigate long-term carryover eff ects of UV-B radiation on behavioral and physiological fitness related traits.

Impact of an active educational video game on children's motivation,science knowledge, and physical activity

Background： Active educational video games （AVGs） appear to have a positive effect on elementary school students＇ motivation leading to enhanced learning outcomes. The purpose of this study was to identify the effectiveness of an AVG on elementary school students＇ science knowledge learning, physical activity （PA） level, and interest-based motivation. Methods： In this randomized controlled study, 53 elementary school students were assigned to an experimental condition or a comparison condition. The experimental condition provided an AVG learning environment, whereas the comparison condition was based on sedentary educational video games. Results： The results of repeated measures analysis of variance （ANOVA） on the knowledge test showed that students in both groups performed better on the post-test than they did on the pre-test （p 〈 0.001, η2 = 0.486）, and their post-test scores did not differ significantly. The experimental condition provided a more active environment since the students＇ average heart rates （HRs） were in the Target-Heart-Rate-Zone （HR = 134 bpm）, which was significantly higher than the average HR （103 bpm） from the comparison condition （t = 7.212, p 〈 0.001）. Students in the experimental condition perceived a higher level of situational interest than their counterparts in the comparison group （p 〈 0.01, and η2 = 0.301）. Conclusion： These results suggest that AVGs benefit children more in terms of PA and motivation than traditional video games by providing an enjoyable learning experience and sufficient PA.

Articulating China's Science and Technology:Knowledge Collaboration Networks Within and Beyond the Yangtze River Delta Megalopolis in China

In this paper, we reconsider the defining but often overlooked ‘hinge' function of megalopolises by analyzing how megalopolises have articulated national and international urban systems in the context of a globalizing knowledge economy. Taking the case of China's Yangtze River Delta(YRD) region, we particularly focus on knowledge circulation within and beyond the YRD region by analyzing the pattern and process of knowledge collaboration at different geographical scales during the 2004–2014 period. Results show that the structure of scientific knowledge collaboration as reflected by co-publications has been strongest at the national scale whereas that of technological knowledge collaboration as measured by co-patents has been strongest at the global scale. Despite this difference, the structure of both scientific and technological knowledge collaboration has been functionally polycentric at the megalopolitan scale but become less so at the national and global scales. The ‘globally connected but locally disconnected' pattern of Shanghai's external knowledge collaboration suggests that the gateway role of the YRD megalopolis in promoting knowledge collaboration at different geographical scales will take time before it is fully realized.

Methane seepages in the northern South China Sea: evidence from in situ measurements

Continental margins in world oceans contain large amounts of marine gas hydrates. Changes in the temperature and pressure of sediment may destabilize the methane hydrate, leading to its release and seepage into the sea. This process would increase the dissolved methane in the ambient seawater. In this study, a methane sensor was used to detect methane anomalies in the water column in southwestern Dongsha and Shenhu, northern slope of the South China Sea. Methane plumes were detected at stations SCS001 and T001 in the southwestern Dongsha area, and station SCS002 in the Shenhu area, respectively. The maximum methane concentrations were 8.8 nmol/L in southwestern Dongsha and 10.1 nmol/L in Shenhu, which are about 4–5 times higher than the background methane concentration. This indicates that there are active methane seepages present in both the southwestern Dongsha and Shenhu areas, which are likely related to a methane hydrate reservoir beneath the seafloor. A methane sensor with a low detection limit is a practical instrument with which to detect methane plumes in oceanic environments and to monitor methane leakage from the seafloor.

Four basic laws in design science

A point on the distinction between design and science is given and the connotanons of aeslgn science are discussed in the paper. Design should be understood as the first step of all human＇ s purposeful activity, which is a daily behavior for everyone. Four laws are summarized, which describe the basic patterns of design and are the constituents of design science. They are the law of design based on existed knowledge, law of in- completeness of design knowledge, law of design centered on new knowledge acquirement and law of competi- tiveness of design knowledge. The four basic laws show the knowledge essence of design. To enrich the existed knowledge, to make it convenient to be used, to teach designers with high intuition and inspiration in picking useful elements of existed knowledge and shaping competitive ideas and to have strong new knowledge acquire- ment facility are the basic conditions of good designs. Study of design science will promote the structure of tra- ditional engineering education. An important conclusion is derived that there will be no successful innovation without good design.

Contribution of ecotourism to poverty alleviation in Nyanga,Zimbabwe

This paper assesses the contribution of ecotourism to local communities and the environment.Livelihoods of local communities are examined to understand the socioeconomic situation of people living in proximity to ecotourism areas and their participation in ecotourism activities. The impact of ecotourism on the environment in Nyanga is also examined. The paper employs both literature review(secondary data) and a field survey(primary data) to achieve these objectives. To gather socioeconomic data of households and tourist traits, questionnaires were administered to120 households and 30 tourists in the study area. Key informant interviews were held in the survey to gather expert knowledge about ecotourism trends and environmental data in the area.Data were analyzed using Statistical Package for Social Sciences. Descriptive and inferential analyses were used for quantitative data while content and structural-functional analyses were used for qualitative data. The research revealed that ecotourism offers the highest salaries when compared to other sources of formal employment. Ecotourism activities were shown to positively impact the environment through the protection, preservation, and management of natural resources. The study concludes that ecotourism is a useful and sustainable poverty alleviation strategy which has not yet been fully exploited in Zimbabwe.

Degradation of lipids in seasonal hypoxic seawater under different oxygen saturation

The hypoxic phenomena of seawater have been found in the Changjiang esturay and its adjacent area for several decades. To study organic matter degradation in seasonal hypoxic seawater, series of stimulated incubation experiments with S keletonema costatum in seawater under different oxygen saturations were conducted. By tracking variations of lipids originated from the alga, time-dependent concentrations of neutral lipids(hexadecanol, otctadecanol, cholesterol, brassicasterol and phytol) and fatty acids(12:0, 14:0, 16:0, 16:1, 18:0, 18:1(9), 20:5 and 22:6) were obtained during three month of incubation. The results indicate that residence time, oxygen saturation, bacterial community and the structure of lipids were key factors controlling preservation and degradation of lipids in seawater. The degradation rate constants calculated from multi-G model showed that under same oxygen saturation, algal fatty acid degraded faster than neutral lipids, and unsaturated fatty acids degraded faster than saturated fatty acids. Our new discovery showed that degradation rate constant had linear positive correlation with oxygen saturation of seawater, indicating the critical role of oxygen on degradation of algal lipids in hypoxic seawater. The results of this study will be helpful to understand organic carbon cycling in seawater and marine environment more deeply. Future field experiments and investigation should be conducted tracking control factors, especially the role of oxygen saturation on organic matter degradation in natural environment.

Kuhn＇s Notion of Theory Choice and the Dual-Process Theory of Cognition

In The Structure of Scientific Revolutions, Kuhn claimed that theory choice is a conversion experience and depends upon the personality or psychology of the individual scientist making the choice. Critics charged Kuhn with an irrational and a relativistic position concerning theory choice, arguing he advocated a subjective instead of an objective approach to how scientists choose one theory over another and thereby undercut epistemic accounts for the generation of scientific knowledge. In response to critics Kuhn insisted that his approach, although subjective, was still rational in that the criteria----vomposed of epistemic values--determining theory choice operate both objectively and subjectively. Recent work in cognitive neuropsychology, particularly in the dual-process theory of cognition, supports Kuhn＇s notion of theory choice. In this paper, I initially discuss Kuhn＇s approach to theory choice, along with criticism of it and his response to the criticism, followed by an examination of the dual-process theory of cognition. I then explore the application of dual-process theory to Kuhn＇s notion of theory choice, especially in terms of a historical case study from the biomedical sciences. I finally discuss briefly the implications of the dual-process theory for contemporary philosophy of science.

Synergetics as a Positivistic ＂Trick＂ for Philosophy

This paper substantiates the idea that particular science reflects only a certain angle of a complex model of the world. Guidance as to ＂adding＂ particular science data in order to achieve a holistic picture of the world is a philosophical outlook. The meaning of each relatively closed system is revealed only in the context of a more capacious system. According to the author, as the material world itself, its epistemic models as well are built according to the principle of ＂matryoshka dolls.＂ The rational and irrational are discussed in the paper as equal moments of scientific knowledge. Contrary to the importance given to randomness in synergy, the author considers if it is possible to find out the causes of all events. In order to do this, other viewpoints and structure levels should be considered. There is a hidden order in every chaos, and that is revealed only in a certain situation. The main issue is taking into account the counter action of the system with the environment.

The Stabilizing Role of Material Structure in Scientific Practice

Knowledge of the environment is essential for the survival of organisms; but those organisms have to have the capacity to stabilize such knowledge. The aim of this article is to analyze the various strategies for stabilizing human knowledge, with a special focus on its material anchors and their interactions with other stabilization means. In particular, I consider how such stabilization is reflected in scientific activity and practice, and what its repercussions are for the models of science that have dominated the philosophical landscape of the 20th century. My starting hypothesis will be that the role of material anchors in stabilizing conceptual blends is analogous to that of technology in grounding scientific knowledge. The framework I adopt with regard to conceptualization is that of Fauconnier and Turner （2002） on conceptual blends. Just as technology intervenes in scientific practice in conjunction with conceptual elements, so do material anchors, which conjoin other non-material strategies of knowledge stabilization. Endowing knowledge with a material basis may be understood firstly as an element （sometimes a key element） for representing knowledge and offering an explanation, and secondly as a way of providing a scientific hypothesis with empirical grounding. It is this second sense that connects with scientific experimentation and the use of instruments and technology.

Behavior of a Nonlinear Difference Equation xn＋1=1-2n/A＋∑k i=1xn-i

In this paper, we investigate the global behavior of the difference equation xn＋1=1-2n/A＋∑k i=1xn-iwith the A ∈ （-∞,-1） is a real number, k is a positive integer and the initial conditions x_k x0 ∈ （-∞, 0].

Why Free Will Is Logically Not Possible within Naturalism

One of the most intriguing problems of philosophy and of mankind is the question whether humans have a free will. This question is heavily disputed between natural scientists and especially neuroscientists, who deny free will, and philosophers and other groups, who insist on free will. It is perplexing that both sides base their premise on the same precondition, namely naturalism. We will prove that naturalism automatically leads to physicalism, to materialism, and to reductionism. We will also prove here that it is logically not possible to have a free will if naturalism is true. Free will definitely requires an additional substance, a non-material soul, which cannot be part of our universe. This must not be in contradiction to our current knowledge of natural sciences.

Metacognition in Solving Process of Basic Electric Circuit ProblemmComparison of Metacognitive Characteristics between Non-major and Major Students in Electric Engineering

There are learners who cannot solve practical problems in spite of mastering basic scientific knowledge and formula necessary for the solution. One of the reasons might be attributed to the lack in metacognitive abilities. The aim of this study was to compare the metacognitive characteristics between non-major and major students in electric engineering and clarify the difference of metacognitive process between these two groups when solving basic problems of electronic circuit. In the experiment, the solving process was compared between non-major and major students in electric engineering using five basic problems. We found that the scores on prediction of result and confidence of own answer differed significantly between non-major and major students, and inferred that the difference of performance was due to the lack in metacognitive ability, especially the plan and the execution abilities. Both prediction of results and confidence of own answer were also found to play a significant role in effective problem solving as important components （subsystems） of metacognition.

Exploring social movement concepts and actions in a knowledge uptake and sustainability context: A concept analysis

Objectives:To share a concept analysis of social movement aimed at advancing its application to evidence uptake and sustainability in health-care.Methods:We applied Walker and Avant method to clarify the concept of social movement in the context of knowledge uptake and sustainability.Peer-reviewed and grey literature databases were systematically searched for relevant reports that described how social movement action led to evidence-based practice changes in health and community settings.Titles,abstracts and full texts were reviewed independently and in duplicate,resulting in 38 included articles.Results:Social movement action for knowledge uptake and sustainability can be defined as individuals,groups,or organizations that,as voluntary and intrinsically motivated change agents,mobilize around a common cause to improve outcomes through knowledge uptake and sustainability.The 10 defining attributes,three antecedents and three consequences that we identified are dynamic and interrelated,often mutually reinforcing each other to fortify various aspects of the social movement.Examples of defining attributes include an urgent need for action,collective action and collective identity.The concept analysis resulted in the development of the Social Movement Action Framework.Conclusions:Social movement action can provide a lens through which we view implementation science.Collective action and collective identity e concepts less frequently canvassed in implementation science literature e can lend insight into grassroots approaches to uptake and sustainability.Findings can also inform providers and change leaders on the practicalities of harnessing social movement action for realworld change initiatives.By mobilizing individuals,groups,or organizations through social movement approaches,they can engage as powered change agents and teams that impact the individual,organizational and health systems levels to facilitate knowledge uptake and sustainability.

The Significance of Horizon in Scientific Cognitive Activities

The hermeneutic concept of horizon contributes to the philosophical understanding of scientific cognition. In the context of scientific cognitive practices, the concept of horizon provides a way of understanding the distinctive characteristics of scientific observation and knowing. Horizon is a key factor that facilitates the cognitive subject to select objects and their backgrounds. In order to make new accomplishment in scientific discoveries, it is essential to broaden the horizon and intzoduce new cognitive instrumentalities and methods. This requires people to be adept at finding out the limitations of their thinking and overcome them consciously. Conscious horizon expansion is essential to the integration of intuition and logical thinking process in scientific cognitive activities, as well as to the establishment of the essential connection/relation between different disciplines and research fields, prompting inter-disciplinary communication and producing methods of thinking. This article is an attempt to explore the significance of horizon for scientific cognition. As we will show, by integrating intuitive thinking and logical thinking through the expansion of horizon, a new cognitive model will be provided.

An Analysis of the Cognitive Constraints of Parody in the Context of Network Media

The language used in the context of network media features variation, flexibility, and comprehensiveness, in which parody is one of the most employed devices. Modern cognitive science prefers to take parody as a cognitive act rather than a sheer linguistic modification act, which has provided a new prospective for further research about parody in the context of network media. This paper aims to probe into the cognitive constraints in the mechanism of parody in the context of network media, in hope to make a detailed explanation of the cognitive process of it and to strengthen the comprehension and appreciation of it.

Complexity and Sociology

This study focuses on the correlation between sociology and complexity and it operates a reflection on the deep epistemological and ontological meaning of complexity, revealing how complexity goes beyond the analysis of the global society and is linked to sociology itself and to the issue of its scientific trait. The study shows how complexity, rediscovered following the globalization processes, reconnects sociology with its own origins and concerns the issue of the relation of sociological science with its own object, that is to say, society and social order. In a more radical manner, the challenge of complexity is intertwined with the road of revisiting modern science and epistemological identifying among ＂order＂, ＂intelligibility＂, and ＂science＂. In such a vision, complexity, not only reconnects sociology to its obiect, but highlights how those traits considered as non-scientific residue of human and social sciences belong to the fundamental issue of scientific knowledge. The challenge of complexity is outlined, as questioning the idea according to which the ＂modern＂ science depletes the ＂scientific vision of the world＂.
