Social Media Usage for Social Comparison and Its Relationship to Identity Development

Yang and colleagues (2018) found that social media comparison was related to identity distress. The purpose of the current study was to expand on their design, by examining multiple comparison factors (i.e., Ability, Opinion, Popularity, Likeness, Physical Appearance, Academic Status/Achievements, Work Status/Achievements, Relationship Status, Family Status, and Socioeconomic Status) and multiple identity development factors (i.e., Ruminative Exploration, Exploration in Breadth, Exploration in Depth, Commitment Making, and Identification with Commitment) on their ability to predict Identity Distress. College students (N= 407) in psychology courses participated in an anonymous online survey for course credit. The results were consistent with the findings of Yang and colleagues (2018) but expands upon their model and thereby adds to the literature on the effects of social media on identity, which raises some important concerns regarding identity development among today’s youth

Magnetic behavior of NiCu nanowire arrays: Compositional, geometry and temperature dependence

Arrays of Ni100-xCux nanowires ranging in composition 0¿=¿x¿=¿75, diameter from 35 to 80¿nm, and length from 150¿nm to 28¿µm have been fabricated by electrochemical co-deposition of Ni and Cu into self-ordered anodic aluminum oxide membranes. As determined by X-ray diffraction and Transmission Electron Microscopy, the crystalline structure shows fcc cubic symmetry with [111] preferred texture and preferential Ni or Cu lattice depending on the composition. Their magnetic properties such as coercivity and squareness have been determined as a function of composition and geometry in a Vibrating Sample Magnetometer in the temperature range from 10 to 290¿K for applied magnetic fields parallel and perpendicular to the nanowires axis. Addition of Cu into the NiCu alloy up to 50% enhances both parallel coercivity and squareness. For the higher Cu content, these properties decrease and the magnetization easy axis becomes oriented perpendicular to the wires. In addition, coercivity and squareness increase by decreasing the diameter of nanowires which is ascribed to the increase of shape anisotropy. The temperature dependent measurements reflect a complex behavior of the magnetic anisotropy as a result of energy contributions with different evolution with temperature

What do people want in a smart city? Exploring the stakeholders’ opinions, priorities and perceived barriers in a medium-sized city in the United States

Many cities in the United States are pursuing agendas to implement ICT-based solutions to tackle urban challenges, thus achieving the ‘smart city’ label. While the discussion on this urban development paradigm has revolved around the intensive use of technologies, the academic literature increasingly calls for shifting the focus to the people living in the cities. This paper argues that to achieve a people-centred smart city, cities should include the perspectives of all the local stakeholders. Under this assumption, this paper provides the views of the local stakeholders in a medium-sized city in Tennessee, Chattanooga. Particularly, this study explores their perceived smart city concept, the ethical standards that should guide smart city projects, the desired future projects in their community, and the barriers to implementing them. The data was collected using a combination of participatory budgeting, five focus groups, and twenty-eight interviews with city dwellers, entrepreneurs, university faculty, non-profit members, and government officials. The results suggest that, far from the image of a highly technological city, the stakeholders envision a city dedicated to improving the quality of life and environmental sustainability. Furthermore, to achieve this smart city, the projects need to be based on full transparency and the promotion of social inclusion. In contrast to the dominant trend towards the privatization of urban space, this study finds that the stakeholders prefer public based smart city projects such as ICT-based public transport services. However, its successful implementation will have to overcome the barriers caused by funding constraints, public acceptance, and political interests. Cities may use the results of this study to design more responsible smart city projects that strike an optimal point between citizen engagement and technological applications and innovations while supporting all stakeholders’ needs.Security and Global Affair

Public knowledge of intelligence agencies among university students in Spain

Public knowledge of both the mission and the powers of the National Intelligence Centre (CNI) are studied in this paper through a survey of 2888 students from 30 universities in Spain. The results confirmed that university students were unaware of the CNI’s mission and powers and that their vision of the CNI was of a Law Enforcement Agency with mainly counter-terrorism functions. Their knowledge differed according to their sociodemographic background and political variables. Both the implications for further scientific debate and the policies of intelligence agencies toward openness are discussed.Security and Global Affair

Understanding the plural landscape of cybersecurity governance in Spain: a matter of capital exchange

This paper empirically explores the contribution and collaborative networks of public and private actors to cybersecurity provision in Spain. The article draws on data from three sources: policy and legal documents, a Delphi study with cybersecurity experts, and 34 interviews. Rooted in the theoretical underpinnings of nodal governance and anchored pluralism, the paper argues that the position of actors and public-private collaboration dynamics involved in cybersecurity governance can be understood through the analysis of capital exchange. Therefore, the study provides a list of the most relevant nodes for cybersecurity in Spain, assesses the capital they possess and how they exchange it through collaborative networks and explores the characteristics and barriers of these collaborative relationships. Analyses reveal that public organisations hold a preeminent position in cybersecurity governance despite large technology corporations’ greater economic and cultural capital. Remarkably, the paper identifies the central position of new public bodies in the network of cybersecurity nodes. Moreover, cultural barriers that are hindering public-private collaboration in Spain are identified. These results indicate that, despite the state’s difficulties in providing public solutions to cybersecurity challenges, Spain is an example of how governance can be anchored in public bodies through symbolic and social capital.Security and Global Affair

From black to white: the regulation of ethical hacking in Spain

Cyber-attacks are exponentially growing, and their impact on systems, people, and organizations increases. Among other challenges, cyber-attacks prevention must tackle the fact that many software systems are marketed with security vulnerabilities due to the companies’ need to reduce time-to-market. One strategy to reduce security vulnerabilities is ethical hacking. However, while ethical hacking can bring many advantages, it also comes with many challenges. This paper introduces a comprehensive study of the possibilities and limitations of ethical hacking in Spain, both empirical and normative. On the empirical side, the paper presents the results of a Delphi study with cyber security experts in Spain on their opinions about the regulation of ethical hacking. In the normative study, the paper critically reviews the possibilities open by the International, European and Spanish law for regulating ethical hacking. The conclusions of this paper offer a roadmap for harnessing ethical hacking to improve cyber security.Security and Global Affair

Lifeguards in the sky: examining the public acceptance of beach-rescue drones

The use of rescue drones is expected to increase in forthcoming years. However, the success of their implementation through different applications will depend on public acceptance. Studies to date have analyzed public support for the use of drones with various applications, although public acceptance of drones in specific contexts remains to be explored. In particular, the use of drones for beach rescues has proven beneficial in reducing response times, thus helping to save lives. In this study, we analyze the public acceptance of lifesaving drones and their associated variables. Data collected from a survey of beach users (N = 3363) for this study are used to measure public acceptance of rescue drones. We found that public acceptance of rescue drones is moderate, with approximately half of all participants accepting their use. In terms of influencing variables, we found that the factors most associated with their use are ‘perceived benefits’ and ‘perceived risks’. We also found that the participants from beaches without lifeguard services were more likely to accept the use of rescue drones. These results initiated a discussion on the variables that are associated with the public acceptance in the specific context of lifesaving. In addition, based on the results of this study, we propose implementation plans for rescue drones that might also include public information campaigns on their benefits for beach usersSecurity and Global Affair
