Engaging or transmitting? Health at the science centre

Science centres have a strong commitment to education, but the implications of that commitment change over time. The discovery pedagogy of the first science centres is gradually being replaced with a more dialogic approach that acknowledges that science has different meanings for different people. Here, we follow the transition of a Danish science centre towards this new approach; a transition driven by the development of a dialogic exhibition on health. To this end, we study the adaptive transformation of scientific content from its origin in scientific literature to its embodiment in the exhibition, using discourse analysis to track its deconstruction and reconstruction. We observe that although the science centre’s established discovery pedagogy does challenge the implementation of dialogic perspectives on health, the participatory approach taken in the development process successfully overcame these challenges. In conclusion, we offer our perspectives on the implications of our findings for science centres.
Gender and the Career Aspirations, Professional Assets, and Personal Variables of Higher Education Administrators

A recent national survey found women hold only 23% of higher education institution presidencies (American Council on Education, 2007). However, women now earn 58% of all bachelor's degrees and 45% of all doctorates (U.S. Department of Education, 2005). These findings suggest something may be interfering with the pool of capable women moving through the pipeline to attain higher education administrative positions. Gender differences in career aspirations, professional assets, and various personal variables have been suggested as potential contributors to this disparity. The purpose of the research was to survey women and men holding administrative positions of dean or higher (excluding presidents) within the institutions in the Minnesota State Colleges and Universities (MnSCU) system to examine these potential contributors. Based on the findings, with the exception of geographic mobility, factors other than career aspirations, professional assets, and personal variables may be the cause of barriers to female advancement to high level administrative positions.
Functional properties and adipogenesis inhibitory activity of protein hydrolysates from quinoa (Chenopodium quinoa Willd.)

Abstract The functional properties and adipogenesis inhibitory activity of quinoa protein hydrolysates, prepared using papain, pepsin, and pancreatin for 0, 30, 60, 90, and 120 min, were studied. For these three kinds of proteases, the solubility of the hydrolysates significantly increased with the increasing DH in pH range of 3–8, while the EAI and ESI of these hydrolysates significantly decreased during hydrolysis. The anti‐inflammatory activity of these protein hydrolysates was measured. All of these protein hydrolysates showed high anti‐inflammatory activity. However, there was no significant difference in anti‐inflammatory activity between protein hydrolysates and total protein from quinoa. These protein hydrolysates also inhibited lipid accumulation during differentiation within the range of concentrations of 0–1,600 μg/ml, which exerted no cytotoxicity toward 3T3‐L1 cells. The protein hydrolysates from quinoa prepared using pepsin for 120 min (PEP‐120) had the highest activity with an IC50 value of 786.58 μg/ml. Moreover, LC‐MS/MS analysis of PEP‐120 showed that five main bioactive peptides, which have been demonstrated to have ACE inhibitor, antioxidant, and antithrombotic activities, were present in PEP‐120. In addition, gene expression and Western blot analysis revealed that PEP‐120 suppressed the 3T3‐L1 cell differentiation through the peroxisome proliferator‐activated receptor γ (PPARγ) pathway.
A NOVEL GAIT-INSPIRED FOUR-BAR LOWER LIMB EXOSKELETON TO GUIDE THE WALKING MOVEMENT

Background: Walking is a complex process that involves rhythmic movement of lower limb along with the coordination of brain, nerves and muscles. If the coordination is disturbed, gait may be effected or disordered. Therefore, it should be treated effectively and efficiently using assistive devices/exoskeletons. The exoskeletons and assistive devices may be embedded with the linkage and other mechanisms to imitate the behavior of human lower limb. However, these mechanisms are synthesized using the complex conventional procedures. Thus, a new gait-inspired algorithm is proposed in this study for synthesizing a four-bar mechanism for exoskeletons.Methods: This paper presents a design of four-bar linkage for lower limb exoskeleton to support walking. A new gait-inspired algorithm to synthesize four-bar linkage is also proposed which uses two phases of gait, namely, the swing phase and the stance phase, for lower limb exoskeleton. The trajectory is derived for each phase of the gait and is combined with the optimization techniques. The trajectory passes through 10 precision points in each phase giving a total of 20 precision points for one gait cycle. The optimization is performed in two stages. The first stage deals with the minimization of error between the desired and the generated foot trajectories; whereas, the second stage deals with the minimization of error between the desired and generated hip trajectories of the linkage. Besides the gait-inspired four-bar linkage synthesis, a hybrid teaching-learning-particle-swarm-optimization (HTLPSO) technique is also used to solve the problem.Results: A well-established genetic algorithm (GA) and a new hybrid (HTLPSO) algorithm are used to compare the results of the tracking error of the linkage. It is found that the HTLPSO optimization algorithm performs better in comparison to GA for the problem considered here. Finally, a solid model of the proposed design for lower limb exoskeleton is presented. Moreover, the obtained linkage tracks all the prescribed points accurately and the simulation of designed linkage has been demonstrated using stick diagram for one gait cycle.Conclusion: The proposed method has simplified the synthesis procedure to a great extent, and a feasible design is obtained using the optimization algorithm. The mechanism obtained using the proposed method can walk smoothly which is validated through stick diagram. The proposed mechanism can be used for exoskeleton, assistive devices, bipeds etc. Moreover, the proposed method may be extended to six- and eight-bar mechanisms.
The Infusion of Technology Within the Classroom Facilitates Students' Autonomy in Their Learning

This experiment investigated whether the infusion of technology in teaching as a scaffolding tool can improve the pass rate of mathematics at the University of Trinidad and Tobago. The use of technology facilitated the building of a virtual classroom which was based on scaffolding, thus aiding students by either peers or the instructor until they are comfortable to move on to the next level. The virtual classroom was used to stimulate discussions on students’ knowledge of mathematics ensuring no focus was on the technology nor the instructor. These discussions provide opportunities for the students to discover his/her existing level within the learning community. Within this learning community, everybody was anonymous including the instructor thus motivating the students to comment on the reflective questions. This encouraged students to collaborate and provide prompt feedback. Suggestions obtained from the students into improving the virtual classroom were considered resulting in four virtual classrooms.
Capacity Measures Explain Only a Small Part of Self-Reported Disability in Institutionalized Ambulatory Older Adults: An Observational Study

Abstract Aims: To investigate the association between self-reported disability and capacity-based measures for older adults attending day care centers and nursing homes. Methods: 312 institutionalized ambulatory older adults were assessed for self-reported disability (WHODAS 2.0), capacity-based measures (gait velocity test, timed up and go test (TUG) and grip strength), demographics, pain and depression. Results: Regression models using self-reported disability as the dependent variable and capacity–based measures as the independent variables explained only 5% and 11% of self-reported disability in older adults from nursing homes and day care centers, respectively. When adding to the regression analysis, pain, depression and demographic variables as independent variables, the final model explained 52% of the variance of self-reported disability both in older adults from day care centers and nursing homes. Conclusion: These results show that self-reported disability and capacity-based measures assess very different constructs and highlight the need for interventions targeting pain and depression as a potential mean to improve self-reported disability.
CAPEST : network capacity and available bandwidth estimation in the data-plane

The measurement of available bandwidth and capacity represents an essential requirement for a multitude of network applications spanning from traffic engineering and admission control to network security. Measurement techniques frequently presume to know capacity a priori, but this constitutes a weak premise in a number of modern scenarios due to conditions such as abstractions in infrastructure virtualization, dynamic demands in resource sharing and fluctuations in interference, all of which can affect capacity in short time spans. Despite consistent efforts, currently employed techniques struggle to balance accuracy, intrusion and freshness, depending on either substantial intrusion, onerous processing or unfeasible deployment. Recent developments on data plane programmability have breathed new life into this undertaking, allowing observation points to be more efficiently distributed and programmable packet methods to be executed in-situ. This dissertation describes CAPEST, a passive capacity and available bandwidth measurement method for the data plane, employing packet dispersion and autocorrelation. The method is evaluated regarding its parametrization sensitivity, its intrusion and freshness in comparison to state-of-the-art techniques and its performance in the real-world application of video routing. CAPEST was found to incur substantially (80%) less intrusion and achieve 10% better accuracy, all the while providing an order of magnitude improvement in freshness.
Understanding N ( d 1 ) and N ( d 2 ) : Risk-Adjusted Probabilities in the Black-Scholes Model 1

This paper uses risk-adjusted lognormal probabilities to derive the BlackScholes formula and explain the factors N(d1) and N(d2). It also shows how the one-period and multi-period binomial option pricing formulas can be restated so that they involve analogues of N(d1) and N(d2) which have the same interpretation as in the Black-Scholes model. Cet article utilise les probabilités lognormaux corrigées du risque pour dériver la formule de Black-Scholes et expliquer les facteurs N(d1) et N(d2). Il montre aussi comment les modèles binomiaux des prix d’options d’une et de plusieurs périodes peuvent être exprimés d’une façon telle qu’ils impliquent des analogues de N(d1) et N(d2) qui ont la même interprétation que dans le modèle de Black-Scholes.
Damage Caps, Motivated Anchoring, and Bargaining Impasse

This paper reports results from a bargaining experiment testing the effect on settlement rates of a damage cap set much higher than the value of the underlying claim. We presented 462 student subjects with materials outlining a personal injury lawsuit and permitted randomly assigned subject pairs to negotiate a pretrial settlement. We find that imposition of a $1 million cap reduced the settlement rate through a process termed “motivated anchoring,” in which a relatively high damage cap disproportionately anchors the plaintiff's estimate of the likely damage award. The result is a widened disparity in opposing litigants' judgments and less settlement. These results contrast with findings from previous experiments where a relatively low cap constrains the parties' judgments and produces more settlement. This pair of results suggests the effect of a cap will depend on its size relative to the stakes of the case.
DEEP GAUSSIAN PROCESS METAMODELING OF SEQUENTIALLY SAMPLED NON-STATIONARY RESPONSE SURFACES

Simulations are often used for the design of complex systems as they allow to explore the design space without the need to build several prototypes. Over the years, the simulation accuracy, as well as the associated computational cost has increased significantly, limiting the overall number of simulations during the design process. Therefore, metamodeling aims to approximate the simulation response with a cheap-to-evaluate mathematical approximation, learned from a limited set of simulator evaluations. Kernel-based methods using stationary kernels are nowadays wildly used. However, using stationary kernels for non-stationary responses can be inappropriate and result in poor models when combined with sequential design. We present the application of a novel kernel-based technique, known as Deep Gaussian Processes, which is better able to cope with these difficulties. We evaluate the method for non-stationary regression on a series of real-world problems, showing that it outperforms the standard Gaussian Processes with stationary kernels.
Preparation, Characterization, and in Vitro/in Vivo Evaluation of Paclitaxel-Bound Albumin-Encapsulated Liposomes for the Treatment of Pancreatic Cancer

Paclitaxel (PTX)-loaded liposomes were developed with the goal of enhancing the effects of cancer treatment. Although loading substances into the lipid membrane of liposome cause some destabilization of the lipid membrane, PTX was nearly exclusively embedded in the lipid membrane of liposomes, due to its low water solubility. Hydrophobic drugs can be encapsulated into the inner core of bovine serum albumin (BSA)-encapsulated liposomes (BSA-liposome) via noncovalent binding to albumin. Since PTX is able to noncovalently bind to albumin, we attempted to prepare PTX-loaded BSA-liposome (PTX–BSA-liposome). The amount of PTX loaded in the BSA-liposome could be increased substantially by using ethanol, since ethanol increases PTX solubility in BSA solutions via prompting the binding PTX to BSA. On the basis of the results of transmission electron microscopy and small-angle X-ray scattering, PTX–BSA-liposome formed unilamellar vesicles that were spherical in shape and the PTX was encapsulated into the inner aqueous core of the liposome as a form of PTX–BSA complex. In addition, the PTX–BSA-liposome, as well as nab-PTX, showed cytotoxicity against human pancreatic cancer cells, AsPC-1 cells, in a PTX concentration-dependent manner. The in vivo antitumor effect of PTX–BSA-liposomes was also observed in a mouse model that had been subcutaneously inoculated with pancreatic cancer cells by virtue of its high accumulation at the tumor site via the enhanced permeability retention effect. These results suggest that PTX–BSA-liposomes have the potential for serving as a novel PTX preparation method for the treatment of pancreatic cancer.

Sterile Insect Technology-Research and Development

1. The use of sterile insects in area-wide integrated pest management (AW-IPM) programmes will continue to expand as increasing constraints are placed on the use of chemical pesticides in relation to the public’s growing demand for a cleaner environment and residue-free food. In addition, the international standards that regulate global agricultural trade, e.g. the World Trade Organization’s (WTO) Agreement on Sanitary and Phytosanitary Standards (SPS), are creating an environment in which area-wide approaches to the management of insect pests have a comparative advantage. Expanding globalization will also lead to the introduction of alien insect pests into new areas and the Sterile Insect Technique (SIT) can be an effective way to deal with these introductions. To counter the impact of increasing pest movement will require increased Research and Development (R&D) to develop the SIT for more species and to integrate the SIT into systems approaches that combine various risk mitigation measures to allow the export of pest free agricultural products and thus overcoming non-tariff trade barriers.
A Study of Multimodal Biometric System Recognition using Different Modalities and Fusion Techniques

Biometrics refers to identity verification of persons according to their physical or behavioral characteristics. Many physical body parts and personal features have been used for biometric systems: fingers, hands, feet, faces, irises, retinas, ears, teeth, veins, voices, signatures, typing styles, gaits, odors, and DNA. Person verification based on biometric features has attracted more attention in designing security systems [1]. However, no single biometrical feature can meet all the performance requirements in practical systems [2]. Most of biometric systems are far from satisfactory in terms of user confidence and user friendliness and have a high false rejection rate FRR. There is a need for development of novel paradigms and protocols and improved algorithms for human recognition. Unimodal biometric systems use one biometric trait to recognize individuals. These systems are far from perfect and suffer from several problems like noise, non-universality, lack of individuality, and sensitivity to attack. Multimodal biometric systems use multiple modalities to overcome the limitations that arise when using single biometric trait to recognize individuals
The Pacific ' s connectivity and its trade implications

Pacific economies are confronted with several structural constraints that limit their economic growth, most importantly their small size and remoteness from major world markets. In this paper we study the importance of transport connectivity for Pacific economies when participating in the world economy. The paper first describes the evolution of trade flows of the Pacific economies over the last decade, in terms of both trade in goods and services. It then introduces two new datasets. One contains all shipping connections within the Pacific and with the rest of the world; the second all flight connections within the Pacific and with the rest of the world. Combining both datasets with the corresponding trade flows allows us to assess the importance of connectivity for the Pacific’s trade performance. Using a gravity model approach, we find that a direct shipping connection more than doubles trade in goods. Similarly, countries with direct flight connections to the sending country welcome twice as many tourists. The frequency of transport connections is similarly important. Using an instrumental variables approach we are able to confirm the robustness of our results. JEL Classification: F14, F15, R40 ADBI Working Paper 499 Helble
Multiple Access for Mobile-UAV Enabled Networks: Joint Trajectory Design and Resource Allocation

In this paper, we investigate joint trajectory design and resource allocation algorithms to maximize the minimum average rate among ground users for unmanned aerial vehicle (UAV) communication systems, where both the orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) modes are considered. We first formulate the problems for UAV communications with the OMA and NOMA modes, respectively, which contain binary variables and highly coupled nonconvex objective functions and constraints. In order to handle the challenging problems, we transform the original problems into more tractable forms and then develop novel algorithms based on penalty dual-decomposition technique to solve them. Simulation results show that the proposed algorithms outperform the benchmarks.
Sustainability, Resilience and Population Ageing along Schengen’s Eastern Border

Border and administrative divisions usually have considerable severe impacts on the economic growth and sustainable management of natural and human on both sides of the border. Schengen border regions mostly perform less well economically in comparison to non-border regions, and the citizens and businesses are facing all sorts of barriers on a day-to-day basis when crossing EU Schengen borders. Therefore, the research is focused on the resilience of the frontier areas of Slovakia and Ukraine, both experiencing rising out-migration, demographic ageing and, therefore, less resistance to threats. The proposed Regional Resilience Index (RRI) is based on three resilience capacity domains: (1) The entrepreneurial domain containing partial indicators of industrial diversity, entrepreneurial activity, unemployment and the possibilities to save money; (2) the socio-demographic domain, whose partial indicators are ageing and the health status of the population, and (3) the domain of interconnectedness of communities with its partial indicators of public infrastructure and settlement stability. By calculating RRI, the overall resilience capacity of the monitored districts of Slovakia and Ukraine is estimated. The index shows that the border factor is significant in explaining the differences in each of the index’s three domains. In addition, migration for work is shown to be a key factor increasing vulnerability and is therefore studied in more detail. The prediction and evaluation of risks associated with strategic and territorial planning is a necessary approach in relation to extraordinary events and minimization of consequences.
Considerations for the Systematic Analysis and Use of Single-Case Research

Single-case research designs provide a rigorous research methodology for documenting experimental control. If single-case methods are to gain wider application, however, a need exists to define more clearly (a) the logic of single-case designs, (b) the process and decision rules for visual analysis, and (c) an accepted process for integrating visual analysis and statistical analysis. Considerations for meeting these three needs are discussed.
