Educational Studies

It is evident that almost nobody is satisfied with contemporary (science) education, however, critique and proposed solutions to the perceived educational problems are sometimes established from opposite reasoning. Nowadays we can witness, for example, debates about position, role and effect of digital mobile technologies, social networks, and many other issues on behaviour and performance of students. Suggestions about their place in science education are on a scale between transforming education toward digital technologies and calls to prohibit, at least some of them, on the other end. Unfortunately enough argumentation too many times follows patterns recognized as ‘The demon-haunted world’ (Sagan, 1995) and a vocabulary and argumentation in line with Frankfurt’s (2005) famous essay ‘On bullshit’.

The chapter deals with a new research field that has arisen at the intersection of scientific experiment and emerging digital technologies. The classical triad of experimental research ‘subject-instrument-object' and its implementation in science education are in the focus of the chapter. The triad is studied in its evolution to a so-called digital triad corresponding to the experimental science of digital society. In the digital triad, each of the three components are transformed. The knowing subject - researcher is transformed to the digital scholar; the experimental instrument is transformed on the base of emerging cloud and mobile technologies; the research object comprising hybrid natural-artificial components emerges. The digital transformations of the experimental research triad and educational practices based on the digital triad are manifested in a number of pioneer inquiry-based projects analyzed in the chapter.

The combine harvest for soybean crops market are currently available two types of combine with header or platform, one of conventional with revolving reel with metal or plastic teeth to cause the cut crop to fall into the auger header and the other called "draper" headers that use a fabric or rubber apron instead of a cross auger, there are few test about performance of this combine header for soybean in Mato Grosso State. The aim of this work was to evaluate the soybean harvesting quantitative losses and performance using two types combine header in four travel speed. The experiment was conducted during soybean crops season 2014/15, the farm Tamboril in the municipality of Pontes e Lacerda, State of Mato Grosso. The was used the experimental design of randomized blocks, evaluating four forward harvesting speeds (4 km h-1, 5 km h-1, 6 km h-1 and 7 km h-1), the natural crops losses were analyzed, loss caused by the combine harvester (combine header, internal mechanisms and total losses) and was also estimated the  field performance of each combine. Data were submitted to analysis of variance by F test and compared of the average by Tukey test at 5% probability. The results show the draper header presents a smaller amount of total loss and in most crop yield when compared with the conventional cross auger.

The growth of agriculture and allied sectors is critical for the Indian economy as about 49 percent of the population is directly or indirectly dependent on agriculture. During the last decade and so, the agriculture sector has undergone profound changes resulting in sharp deceleration in its growth. The study has attempted to analyze growth and performance of the agriculture sector in India since 1980-81 and tries to comprehend some of the factors responsible for the deceleration in growth. The study has shown that agriculture sector has been able to show tremendous improvement in expansion of area and production of food grain and non-food grain crops. However, there are so many underlying factors responsible for slowdown of the agricultural growth. Some of the factors identified include: Increase in area under non-agriculture uses, excessive dependence on rain fed farming, increase in number of agricultural labourers, reducing size of the operation holdings, over use of agri-inputs, inequity in the distribution of agriculture credit along with sharp deceleration in public gross capital formation in agriculture etc. The study pointed in order to achieve higher growth rate, there is a need to enhance the gross capital formation in agriculture sector particularly on irrigation so that more area can be brought under assured irrigation. Bringing equity in distribution of agricultural credit coupled with judicious and need-based agricultural inputs are some of the other recommendations drawn based upon the study.

AbstractLocation-based services are becoming more and more popular in mobile online social networks (mOSNs) for smart cities, but users’ privacy also has aroused widespread concern, such as locations, friend sets and other private information. At present, many protocols have been proposed, but these protocols are inefficient and ignore some security risks. In the paper, we present a new location-sharing protocol, which solves two issues by using symmetric/asymmetric encryption properly. We adopt the following methods to reduce the communication and computation costs: only setting up one location server; connecting social network server and location server directly instead of through cellular towers; avoiding broadcast encryption. We introduce dummy identities to protect users’ identity privacy, and prevent location server from inferring users’ activity tracks by updating dummy identities in time. The details of security and performance analysis with related protocols show that our protocol enjoys two advantages: (1) it’s more efficient than related protocols, which greatly reduces the computation and communication costs; (2) it satisfies all security goals; however, most previous protocols only meet some security goals.

Network Power

Social media influencers-individuals who utilize various forms of network power on social networks occupy a unique identity space. On the one hand, their network power is often tied to their social identity as creators of engaging material. On the other hand, their ability to promote commercial products and services steps outside the traditionally distinct commercial–social, occupational–personal divides. In this work, the network morphologies of influencers are explored in relation to their delivery of sponsored and non-sponsored content. This article explores how the disclosure of content as ‘sponsored’ affects audience reception. We show how that the promotion of content on social media often generates higher levels of engagement and receptiveness amongst their audience despite the platform’s assumption of organic non-commercial relationships. We find that engagement levels are highest among smaller out-degree networks. Additionally, we demonstrate that sponsored content not only returns a higher level of engagement, but that the effect of sponsorship is relatively consistent across out-degree network sizes. In sum, we suggest that social media audiences are not sensitive to commercial sponsorship when tied to identity, as long as that performance is convincing and consistent.

In previous research, there exists some debate about the effects of musical training on memory for verbal material. The current research examines this relationship, while also considering musical training effects on memory for musical excerpts. Twenty individuals with musical training were tested and their results were compared to 20 age-matched individuals with no musical experience. Musically trained individuals demonstrated a higher level of memory for classical musical excerpts, with no significant differences for popular musical excerpts or for words. These findings are in support of previous research showing that while music and words overlap in terms of their processing in the brain, there is not necessarily a facilitative effect between training in one domain and performance in the other.

Understanding human cognitive evolution, and that of the other primates, means taking sociality very seriously. For humans, this requires the recognition of the sociocultural and historical means by which human minds and selves are constructed, and how this gives rise to the reflexivity and ability to respond to novelty that characterize our species. For other, non-linguistic, primates we can answer some interesting questions by viewing social life as a feedback process, drawing on cybernetics and systems approaches and using social network neo-theory to test these ideas. Specifically, we show how social networks can be formalized as multi-dimensional objects, and use entropy measures to assess how networks respond to perturbation. We use simulations and natural ‘knock-outs’ in a free-ranging baboon troop to demonstrate that changes in interactions after social perturbations lead to a more certain social network, in which the outcomes of interactions are easier for members to predict. This new formalization of social networks provides a framework within which to predict network dynamics and evolution, helps us highlight how human and non-human social networks differ and has implications for theories of cognitive evolution.

ABSTRACTA comparative study investigating the integration of supplemental teaching resources in materials science education was developed for the purpose of determining the effectiveness of teaching strategies. Digital stories created by students, excerpts from the Nova Making Stuff documentaries, YouTube educational videos and student generated demo-kits were used as part of the investigation whereby two 9th grade science classes (n~26) were evaluated. Each participant in the study received one period (40-min) of a traditional lesson on Materials Science including specific content, vocabulary, and a pre- and post- lesson assessment. Additionally, the students in each class participated in a 30-min supplemental component, e.g. video or activity-based demonstration using aforementioned kits or video compilation. Pre- and post- evaluations (e.g. open-ended and likert questions) were administered to all of the participants. As hypothesized, the students’ feedback and performance on assessment activities reveal that the use of multimedia and activity-based resources may be equally effective teaching methods as traditional methods.

Purpose With the ubiquitous diffusion of mobile-enabled internet, individuals are constantly immersed in both virtual and physical environments. While this causes distractions, lower attention spans and disasters such as texting while driving and walking, it also creates synergies and smoother navigational experiences. Technology developers, marketers and policy-makers are both concerned and intrigued to understand how to deploy these mobile technologies so as to optimize their disruptive impact. In this paper, the authors aim to develop a framework of dual consciousness to understand the potential causes and outcomes of individual’s simultaneous presence in physical and virtual worlds. Design/methodology/approach A careful review of past academic literature on behavior, as well as media reports of incidents of disruptions, led the authors to construct a 2 × 2 framework depicting behaviors that indicated high-low consciousness in physical, as well as virtual worlds. Findings In dual environments, individuals either dissociate from one of the environments or integrate both environments. While the former is driven by the multiplicity of irrelevant roles and goals, oblivion of relevant roles, perception of group norms and performance of practiced routine tasks, the latter is driven by strong executive control processes, focused singular goals and usage of the virtual environment to reinforce their physical tasks. The most affected parties are retailers, service providers, digital marketers and social media marketers. Originality/value Most prior research in interactive marketing examine effects of online stimuli on online behavior. This paper identifies the noise created by physical context on clicks as well as the interference created by virtual stimuli on physical purchases and service experiences.
