Authors: Martins Ines , Estaún Santiago 
Published: October 2020

El presente artículo tiene como objetivo analizar el cine como medio de expresión y
representación de un determinado contexto sócio-histórico y como herramienta pedagógica en la formación de sujetos críticos y activos en su contexto social. En primer lugar, se ha analizado la representación de la adolescencia en las películas Kids y Ken Park de Larry Clark, a través del análisis semiótico del film. Posteriormente, se han contrastado las divergencias o coincidencias entre la representación de la adolescencia norteamericana en el cine y los datos
encontrados en los estudios científicos sobre la misma. De manera general se puede concluir que: 1) el cine es un vehículo de comunicación, influencia y re-presentación sociocultural y como tal está condicionado por su entorno y reflejará elementos significativos de su época. 2) la función social del cine le convierte en una excelente herramienta pedagógica en la educación del pensamiento crítico, y sujetos activos en el acto de ver, pensar, interpretar y analizar una determinada realidad.

De uitkoopprocedure en afgeleide schade. Billijke verhoging in de uitkoopprocedure: the law is on the move
In dit artikel staan twee spraakmakende uitkoopprocedures centraal: Xeikon en Sirowa. De Ondernemingskamer oordeelde in deze uitkoopzaken dat (mogelijke) vorderingen tot schadevergoeding van de vennootschap op derden – en daarmee samenhangend met de door de minderheidsaandeelhouder geleden afgeleide schade – van belang kunnen zijn bij het vaststellen van de uitkoopprijs. Om de (mogelijke) vorderingen op derden te betrekken bij de prijsvaststelling trok zij een parallel met de ratio van de billijke verhoging als bedoeld in art. 2:343 lid 4 BW. In dit artikel onderzoekt de auteur hoe deze benadering past in het leerstuk van de afgeleide schade en zoomt hij nader in op de manier waarop de Ondernemingskamer de uitkoopprijs vaststelde in deze uitkoopprocedures.
Malicious Cyber Operations, “Hackbacks” and International Law: An Austrian Example as a Basis for Discussion on Permissible Responses
Authors: Schweighofer Erich , Brunner Isabella , Zanol Jakob 
Published: October 2020

In January 2020, Austria publicly announced that some of its governmental institutions have been hit by a significant malicious cyber operation and that it cannot be denied – at least for the moment – that a state was behind this operation. One month later, the Austrian Foreign Ministry declared the cyber operation to be officially over. While Austria noted that it took “countermeasures” against the operation, it is not entirely clear what it meant by that. This article elaborates the question what response options a state like Austria would have against a malicious cyber operation under the current framework of international law. It, hence, tries to answer when a “hackback” is lawful under international law and when it is not.
Council of Europe Recommendation CM/Rec(2017)5 and e-Voting Protocol Design
Authors: Müller-Török Robert , Bagnato Domenica , Prosser Alexander 
Published: October 2020

The Corona pandemic has created a push towards digitization in a number of fields, not least in the public sector including democratic processes. This of course includes an increased interest in e-voting via the Internet. The Council of Europe has a long-standing history of work in the field including two Recommendations – (2004)11 and (2017)5 – which have become the de facto yardstick against which every e-voting system is measured. Rec(2017)5 builds on a decade of experience with e-voting and particularly strengthens two concepts important in any electronic voting system: Voting secrecy and auditability/verifiability. This has distinct implications for the design of e-voting protocols. The aim of this paper is to analyse the impact on what arguably are the most popular voting protocol families, envelope and token protocols. How does the modified Recommendation impact on the viability of protocols and protocol design? The paper first presents the Council of Europe Recommendation and the technical issues it addresses. Then a model is introduced to assess a voting protocol against the Recommendation; a typical envelope and a token protocol are assessed in view of the model and finally the two assessments are compared including policy recommendations for a path to e-voting implementation.
The Senior Military Officer as a Veteran in Transition: Opportunities for Adult Learning and Bridging the Military–Civilian Divide
Authors: Biniecki Susan M. Yelich , Berg Paul 
Published: October 2020

AbstractRetiring senior military officers (SMO) are a specific group of adult learners in role transition. SMOs have the shared experience of high‐level leadership roles, senior managerial experiences, and military rank. They experience some similar transition challenges as other military affiliated learners, such as military–civilian culture; however, in their military roles, these individuals are in powerful roles of command, often in high stress to include life and death combat situations. Therefore, the SMO adult learner transitioning into post‐retirement, second career work experiences has important context changes to explore. Those context changes include integrated ways of moving among levels of novice to expert in organizational structure, ethos, international experience, and managing and leading in crisis. Through reciprocal learning programs, hiring organizations and SMOs have an opportunity to make headway into bridging the military–civilian divide.

Published: October 2020

AbstractThe aim of this chapter is to examine an entrepreneurial training program using a theoretical foundation to assess pedagogical and programmatic outcomes. First, the chapter begins by reviewing military veteran entrepreneurship. Next, key constructs previously shown to impact entrepreneurial capabilities and intentions are reviewed. Subsequently, the case used in this study of an entrepreneurial education program is shared, along with how the program impacted a cohort of military veterans. Finally, we provide a discussion about how these results should influence thinking about entrepreneurial training programs for veterans.

Published: October 2020

AbstractThe transitioning of veterans, specifically as mature workers, from the military world to the civilian world, and by extension, the civilian workforce is the ultimate career transition. Despite their motivation and resilience, veterans still encounter a multiplicity of challenges when transitioning to the civilian workforce, which quite often has a rippling impact on their attainment of employment, career development, employee engagement, and job satisfaction within the civilian sector. On this premise, the purpose of this conceptual paper is two‐fold: (a) discuss veterans’ career transitional challenges as civilian employees, specifically, recruitment, career development, engagement, and job satisfaction, and (b) from a Human Resource Development perspective, provide strategies, interventions, and/or best practices for recruiting, developing, engaging, and satisfying the veteran employee in the civilian workforce.
The effects of collaboration and punishment on prospective memory performance in a group setting
Authors: Altgassen Mareike , Cohen Anna‐Lisa , Jansen Michelle G. 
Published: October 2020

SummaryRemembering to perform a delayed intention is termed prospective memory (PM). Often delayed intentions are shared by more than one person; however, there is a dearth of studies examining PM in social settings. We aimed to investigate whether the potential consequences of one's behavior across diverse group settings influence PM performance in event‐ and time‐based tasks. A total of 207 participants were randomly allocated to either an individual, collaborative, or collaborative plus penalty motivation condition and were tested in a 2‐ or 3‐person setting. For the time‐based PM task, participants responded less timely in the individual motivation condition, whereas there was no difference between the collaborative motivation conditions. No significant effects were found for motivation condition on the event‐based task or for group size on PM performance. Analyses of ongoing task performance revealed that participants' attention allocation policies change depending on how individuals prioritize the ongoing and PM tasks.

AbstractLead zirconate titanate (PZT)‐based piezoelectric ceramics are important functional materials for various electromechanical applications, including sensors, actuators, and transducers. High piezoelectric coefficient and mechanical quality factor are essential for the resonant piezoelectric application. However, since these properties are often inversely proportional, simultaneously high performances are hard to achieve, consequently, a wide range of applications are strongly restricted. In the present study, exceptionally well‐balanced performances are achieved in PZT‐based ceramics via innovative defect engineering, which involves multi‐scale coordination among defect dipole, domain‐wall density, and grain boundary. These materials are superior to many state‐of‐the‐art commercial counterparts, which can potentially satisfy high‐end requirements for advanced electromechanical applications, such as energy harvesting, structural health monitoring, robotic sensors, and actuator.

AbstractVolumetric additive manufacturing (VAM) forms complete 3D objects in a single photocuring operation without layering defects, enabling 3D printed polymer parts with mechanical properties similar to their bulk material counterparts. This study presents the first report of VAM‐printed thiol‐ene resins. With well‐ordered molecular networks, thiol‐ene chemistry accesses polymer materials with a wide range of mechanical properties, moving VAM beyond the limitations of commonly used acrylate formulations. Since free‐radical thiol‐ene polymerization is not inhibited by oxygen, the nonlinear threshold response required in VAM is introduced by incorporating 2,2,6,6‐tetramethyl‐1‐piperidinyloxy (TEMPO) as a radical scavenger. Tuning of the reaction kinetics is accomplished by balancing inhibitor and initiator content. Coupling this with quantitative measurements of the absorbed volumetric optical dose allows control of polymer conversion and gelation during printing. Importantly, this work thereby establishes the first comprehensive framework for spatial–temporal control over volumetric energy distribution, demonstrating structures 3D printed in thiol‐ene resin by means of tomographic volumetric VAM. Mechanical characterization of this thiol‐ene system, with varied ratios of isocyanurate and triethylene glycol monomers, reveals highly tunable mechanical response far more versatile than identical acrylate‐based resins. This broadens the range of materials and properties available for VAM, taking another step toward high‐performance printed polymers.

AbstractNanoparticle‐based magnetic hyperthermia is a well‐known thermal therapy platform studied to treat solid tumors, but its use for monotherapy is limited due to incomplete tumor eradication at hyperthermia temperature (45 °C). It is often combined with chemotherapy for obtaining a more effective therapeutic outcome. Cubic‐shaped cobalt ferrite nanoparticles (Co–Fe NCs) serve as magnetic hyperthermia agents and as a cytotoxic agent due to the known cobalt ion toxicity, allowing the achievement of both heat and cytotoxic effects from a single platform. In addition to this advantage, Co–Fe NCs have the unique ability to form growing chains under an alternating magnetic field (AMF). This unique chain formation, along with the mild hyperthermia and intrinsic cobalt toxicity, leads to complete tumor regression and improved overall survival in an in vivo murine xenograft model, all under clinically approved AMF conditions. Numerical calculations identify magnetic anisotropy as the main Co–Fe NCs’ feature to generate such chain formations. This novel combination therapy can improve the effects of magnetic hyperthermia, inaugurating investigation of mechanical behaviors of nanoparticles under AMF, as a new avenue for cancer therapy.

Published: October 2020

AbstractA new concept of thin, flat, transparent variable lenses with unprecedented performance in terms of active diameter and focal distance range is presented. The diffractive lens consists of two cascaded variable liquid crystal‐based spiral diffractive lenses. Changing concertedly the topological charge changes the focal length with no mechanical motion. The implemented lens has a focal range from –2 to +2 diopters, an active diameter of 25 mm, a low operating voltage (<10 V), and a fill factor of 98%. These characteristics are unique in planar tunable lenses, opening for applications ranging from human vision correction to space applications.
Systems with greater perenniality and crop diversity enhance soil biological health
Authors: Sprunger Christine D. , Martin Tvisha , Mann Meredith 
Published: October 2020

AbstractSoil health has received heightened interest because of its association with long‐term agricultural sustainability and ecological benefits, including soil carbon (C) accumulation. We examined the effects of crop diversity and perenniality on soil biological health and assessed impacts on mineralization and C stabilization processes across 10 systems including four no‐till annual row crops, two monoculture perennials, and four polyculture perennials. Crop diversity increased soil biological health in both annual and perennial systems. Rotated annuals with a cover crop increased permanganate oxidizable C (POXC) and soil organic matter relative to continuous corn (Zea mays L.). Perennial polycultures also had 88% and 23% greater mineralizable C relative to the annual and monoculture perennial systems, respectively. All polyculture perennials had significantly greater POXC relative to switchgrass (Panicum virgatum L.) and annual systems, with the exception of restored prairie. Of the systems assessed in this study, incorporating perennial polycultures into rotations is the most effective way to increase soil biological health and enhance C stabilization.

AbstractThermoelectrochemical cells (thermocells) designed for harvesting human body heat can provide constant power output for wearable electronics, supplementing state‐of‐the‐art flexible power storage and conversion solutions. However, a systematic investigation into the optimization of wearable thermocells is lacking, especially with regard to device design, n‐type electrolytes, and electrode/electrolyte integration. Here, a n‐type gel electrolyte: polyvinyl alcohol‐FeCl2/3 with outstanding flexibility and elasticity and exceptional electrolyte/electrode integration into a 3D porous poly(3,4‐ethylenedioxythiophene)/polystyrenesulfonate (PEDOT/PSS) electrode, is produced via an in situ chemical crosslinking method. The integrated n‐type cell shows excellent seebeck coefficients (0.85 mV K−1) and output current density (1.74 A m−2 K−1) that are comparable with an optimized p‐type cell consisting of a carboxymethylcellulose‐K3/4Fe(CN)6 electrolyte with a 3D PEDOT/PSS‐edge functionalized graphene/carbon nanotube electrode (−1.22 mV K−1 and 1.85 A m−2 K−1). The equivalent performance of the n‐type and p‐type cells enables the effective series connection of up to 18 pairs of p–n cells that combines to give an output voltage of 0.34 V (∆T = 10 K). This in‐series device is fabricated into a proof‐of‐concept watch strap, which can harvest body heat, charge supercapacitor (up to 470 mF) as well as illuminate a green light emitting diode, demonstrating the practical applications.

AbstractThe future of primates depends on conservationists in primate range countries having the education and opportunities needed to facilitate conservation efforts. However, most primates are found in countries where conservation is underfunded. Rwanda is home to 14 primate species, with three being listed as endangered on the International Union for Conservation of Nature (IUCN) Red List. Their remaining native habitats are scarce, highly fragmented, and surrounded by high human densities. Lacking education opportunities and the loss of qualified individuals following decades of political instability created a need for well‐trained conservationists to tackle conservation challenges in Rwanda. The Memoirs Program, a science capacity‐building partnership between Dian Fossey Gorilla Fund (DFGF), University of Rwanda (UR), the Rwanda Development Board, and Cleveland Metroparks Zoo, aims to train the next generation of Rwandan conservationists. Annually, the Memoirs Program provides 10–12 top students from the UR Conservation Biology undergraduate program the opportunity to conduct senior research projects (Memoirs) at DFGF addressing conservation issues in and around Rwanda's protected areas. Students receive one‐on‐one supervision by DFGF scientists and affiliates to supplement UR mentorship, along with targeted teaching modules that reinforce and complement UR curricula. In continuation of the Memoirs Program, participants are offered professional development, employment opportunities, and support to publish their research in peer‐reviewed journals. Since inception of the Program in 2003, 123 students have participated with 83% being employed or pursuing higher education degrees in conservation‐related fields in Rwanda and the region. Pre‐ and post‐training comparison of oral presentation skills, one of the teaching modules, involving 22 students demonstrated increased post‐training performance. The Memoirs Program represents an effective partnership between the government, an international conservation non‐governmental organization, and a public higher‐learning institution in a developing country to support high‐performing students to become tomorrow's conservation leaders. This model could be replicated within Rwanda and in other regions of the world.

Published: October 2020

AbstractOxygenation reactions with molecular oxygen (O2) as the oxygen source provides a green and straightforward strategy for the construction of O‐containing compounds. Demonstrated here is a novel N‐heterocyclic carbene (NHC) catalyzed oxidative transformation of simple and readily available organic halides into valuable esters through the incorporation of O‐atoms from O2. Mechanistic studies prove that the deoxy Breslow intermediate generated in situ is oxidized to a Breslow intermediate for further transformation by this oxidative protocol. This method broadens the field of NHC catalysis and promotes oxygenation reactions with O2.
