QR CODE ACCESSED VIDEO-BASED INSTRUCTION TO TEACH VOCATIONAL SKILLS TO STUDENTS WITH MODERATE TO SEVERE DISABILITIES

The purpose of this study was to determine the effects of QR code (quick reference) linked video-based instruction (VBI) on daily vocational skills for students with moderate to severe disabilities (MSD). A multiple probe across participants was used to evaluate the effectiveness of VBI accessed through scanning a QR code. During technology training a system of least prompts was used to teach students to unlock the iPod, scan the QR code, press play, and press pause between each step of the task; after reaching mastery, students entered into the intervention condition (VBI). During VBI an immediate change in level was observed across three particpants. This study found a functional relationship between VBI and the completion of vocational tasks

Commuting times and the mobilisation of skills in emergent cities

Labour mobility within a large city or metropolitan area is a necessary condition for the optimal exploitation of agglomeration economies. We propose a method to establish which municipalities should be considered part of a metropolitan area based on labour market integration. In order to aggregate geographically proximate urban municipalities, we develop a network-based model that makes industry productivity (manifesting in formal employment creation) dependent on firms’ ability to find, within city limits, the diversity of skills they need to move to new complex industries. In this way, we uncover the natural city scale at which firms optimally exploit the range of skills available to them within a broad catchment area. Considering Colombian cities, we find that commuting times between 45 and 75 min, corresponding to between 43 and 62 distinct cities or integrated labour markets, allow firms to maximise formal employment creation (between 2008 and 2013). This result supports the development of passenger transport limiting commuting times within cities, connecting small- and mid-size cities to nearby large cities, and coordinating transportation investments across traditional administrative boundaries

Accurate Noise Projection for Reduced Stochastic Epidemic Models

We consider a stochastic Susceptible-Exposed-Infected-Recovered (SEIR) epidemiological model. Through the use of a normal form coordinate transform, we are able to analytically derive the stochastic center manifold along with the associated, reduced set of stochastic evolution equations. The transformation correctly projects both the dynamics and the noise onto the center manifold. Therefore, the solution of this reduced stochastic dynamical system yields excellent agreement, both in amplitude and phase, with the solution of the original stochastic system for a temporal scale that is orders of magnitude longer than the typical relaxation time. This new method allows for improved time series prediction of the number of infectious cases when modeling the spread of disease in a population. Numerical solutions of the fluctuations of the SEIR model are considered in the infinite population limit using a Langevin equation approach, as well as in a finite population simulated as a Markov process.Comment: 38 pages, 10 figures, new title, Final revision to appear in Chao

Switching barrier scaling near bifurcation points for non-Gaussian noise

We study noise-induced switching of a system close to bifurcation parameter values where the number of stable states changes. For non-Gaussian noise, the switching exponent, which gives the logarithm of the switching rate, displays a non-power-law dependence on the distance to the bifurcation point. This dependence is found for Poisson noise. Even weak additional Gaussian noise dominates switching sufficiently close to the bifurcation point, leading to a crossover in the behavior of the switching exponent

Accuracy in Rating and Recommending Item Features

This paper discusses accuracy in processing ratings of and recommendations for item features. Such processing facilitates featurebased user navigation in recommender system interfaces. Item features, often in the form of tags, categories or meta-data, are becoming important hypertext components of recommender interfaces. Recommending features would help unfamiliar users navigate in such environments. This work explores techniques for improving feature recommendation accuracy. Conversely, it also examines possibilities for processing user ratings of features to improve recommendation of both features and items. This work’s illustrative implementation is a web portal for a museum collection that lets users browse, rate and receive recommendations for both artworks and interrelated topics about them. Accuracy measurements compare proposed techniques for processing feature ratings and recommending features. Resulting techniques recommend features with relative accuracy. Analysis indicates that processing ratings of either features or items does not improve accuracy of recommending the other

Triple Aims Healthcare Policy Voices of Graduate Student Interprofessional Team Members

The purpose of this study is to share the voices of healthcare graduate students participating in an interprofessional course experience, particularly as their voice relate to fundamental healthcare issues care embodied in the Triple Aims. Two research questions guided study efforts: (1) how do graduate students perceive the value of interprofessional learning experiences for their professional development as future healthcare providers? and (2) based on these experiences, how do students perceive the potential for interprofessional teams to address the Triple Aims of health care? This study was based on the qualitative approach of inductive thematic coding (Braun & Clarke, 2006). Findings indicated that course experiences led to favorable perspectives towards interprofessional practice, with students citing particular benefits regarding more effective and efficient patient service. Students also perceived that interprofessional healthcare would advance current practice regarding the first two triple aims (patient healthcare outcomes and patient satisfaction) due its focus on patient-centered care, improved provider communication, and better-informed treatment decisions. Regarding the third triple aim (reduced costs), students noted that healthcare cost savings were possible, but these must be viewed with a macro lens from a long-term perspective

Strategy and creativity in the use of political slogans: A study of the elections held in Spain in 2019

The unquestionable predominance of slogans in political communication versus their declining relevance in the commercial kind underpins the objective of this study, which is to gain further insight into the strategies and creative discourses employed by political parties in their campaigning before the general, regional and local elections held in Spain in 2019, whereby the results are compared with those obtained in previous research. The aim is thus to determine the attributes of electoral slogans regarding such aspects as their semantic density, complexity, use of rhetorical devices, core focus or communication efficiency. Accordingly, this study is framed in the field of research on political advertising, employing content analysis. To this end, an analysis was performed on an extensive corpus of 197 slogans, selected according to the criteria of comprehensiveness, relevance and representativeness. In short, it can be claimed that the tendencies noted in previous studies have stabilized, albeit with some new developments in relation to briefness, the use of double or triple slogans, expressive focus, bilingualism, the use of visual resources (such as emoticons) or digital language (contractions), the presence of rhetorical devices, and the relevance of voters and candidates versus political parties, among other factors. Besides the specific evolution of their formal and content-related aspects, we argue that the relevance of political slogans still prevails, and rather than undermining their essence and uses, the advent of social media has instead enhanced them

EXPERIMENTAL ERROR IN AGRONOMIC FIELD TRIALS

Agronomic experiments often summarize work carried out in trials run in several locations over several years, referred to generically as environments. The appropriate statistical analyses for these experiments depend on definitions used for experimental error. The results of one such experiment, in which identical designs were used in each environment, illustrate the commonalities and differences in analyses that can result from using different definitions of experimental error
