En este artículo se describen y analizan los resultados de un estudio exploratorio sobre el uso de Internet -más concretamente el World Wide Web (WWW)- por parte de un grupo de estudiantes universitarios para documentarse a la hora de desarrollar tareas académicas. Los datos -obtenidos a través de un cuestionario auto-administrado - ponen de manifiesto la escasa competencia de este alumnado para la búsqueda y manejo de información contenida en el ciberespacio.

Se pretende: calibrar la extensión del uso del WWW como fuente de información para actividades académicas, analizar qué buscadores son los más utilizados y cómo se utilizan, analizar la destreza de los estudiantes en la búsqueda de información para fines académicos, averiguar para qué actividades académicas se usa Internet, describir las principales ventajas e inconvenientes de buscar información en Internet, analizar la extensión en el uso de los principales recursos existentes en Internet para localizar información y, finalmente, analizar cómo han aprendido los estudiantes de la UIB a buscar información en el WWW. Los datos han sido recogidos mediante un cuestionario compuesto por 21 preguntas (16 cerradas o mixtas y 5 de respuesta abierta). El cuestionario fué suministrado a lo largo del mes de Abril de 2006 a 79 estudiantes (71 mujeres y 8 hombres: 32 de primer curso, 31 de segundo y 16 de tercero. Los datos obtenidos fueron analizados estadísticamente con el programa de tratamiento estadístico de datos SPSS 12.0 y la información recogida a través de las preguntas abiertas fué explotada con el programa de análisis de datos cualitativos NUDIST. Se puede afirmar que Internet es la principal fuente de información utilizada por los estudiantes para desarrollar sus actividades académicas. El uso que hacen de Internet es muy superior al de las bibliotecas, usan estrategias de búsquedas en Internet muy simples y poco depuradas. Tienen un autoconcepto bastante positivo de sus habilidades y capacidades para buscar información con fines académicos a través de Internet. Se percibe una 'googlelización' acusada en la búsqueda de información en Internet entre los estudiantes. Los estudiantes no tienen una adecuada estrategia de selección de la información localizada. Los alumnos reducen drásticamente su búsqueda de información a la publicada en sus idiomas maternos (castellano y catalán en el caso del grupo analizado) y no buscan información en otros idiomas. La comodidad, el gran número de recursos que ofrece y la actualización de los contenidos son, en este orden, los principales beneficios percibidos por los estudiantes asociados al uso de Internet como fuente de información académica. Los principales inconvenientes percibidos son: la pérdida de tiempo para encontrar información por culpa de la gran cantidad de recursos disponibles, dificultad para encontrar lo que uno desea y la gran cantidad de información 'basura' o no rigurosa que existe en la red. Los estudiantes han aprendido a buscar y encontrar información en Internet de manera autónoma e intuitiva, sin una guía o asesoramiento de apoyo. Internet se usa básicamente para preparar trabajos y, en menor medida, para ampliar temarios y preparar exámenes.

 The incursion of Internet has created new forms of information and communication. As a result, today’s generation is culturally socialized by the influence of information and communication technologies in their various forms. This has generated a series of characteristics of social and cultural behaviour which are derivative of didactic, academic or recreational use. Nevertheless the use of the Internet from an early age represents not only a useful educational tool; it can constitute a great danger when it is used to access contents unsuitable for their adaptive development. Accordingly, it is necessary to study the legal regulation of internet content and to evaluate how such regulation may affect rights. Further, it is also important to study of the impact and use of this technological tool at level of the familiar unit, to understand better how it can suggest appropriate social mechanisms for the constructive use of Internet. The present investigation involves these two aspects with the purpose of uniting the legal and social perspective in a joint analysis that allows one more a more integral vision of this problem of great interest at the global level.

The present study aimed at comparing social representations structures concerning data collection procedures: through internet forms, diffused in the WWW, and through conventional paper and pencil questionnaire methods. overall 893 individuals participated in the research, 58% of whom were female. A total of 217 questionnaires about the social representation on football (soccer) and 218 about the representation on aging were answered by Brazilian university students in classrooms. Electronic versions of the same instrument were diffused through an internet forum linked to the same university. There were 238 answers for the football questionnaire and 230 for the aging one. The instrument asked participants to indicate five words or expressions related to one of the social objects. Sample characteristics and structural analyses were carried out separately for the two data collection procedures. data indicated that internet-based research allows for higher sample diversity, but it is essential to guarantee the adoption of measures that can select only desired participants. Results also pointed out the need to take into account the nature of the social object to be investigated through internet research on representations, seeking to avoid self-selection effects, which can bias results, as it seems to have happened with the football social object.

It is now possible to directly link the human nervous system to a computer and thence onto the Internet. From an electronic and mental viewpoint this means that the Internet becomes an extension of the human nervous system (and vice versa). Such a connection on a regular or mass basis will have far reaching effects for society. In this article the authors discuss their own practical implant self-experimentation, especially insofar as it relates to extending the human nervous system. Trials involving an intercontinental link up are described. As well as technical aspects of the work, social, moral and ethical issues, as perceived by the authors, are weighed against potential technical gains. The authors also look at technical limitations inherent in the co-evolution of Internet implanted individuals as well as the future distribution of intelligence between human and machine.

The chapter reports on the ‘This Is Me’ project, that aimed to help students and the wider public to be aware of the impact that online material, particularly that on the Internet, has on their identity and reputation. The chapter explores practical aspects of Digital Identity, relating to issues such as employability, relationships and even death. For example, understanding the impact a photograph posted on a social networking website might have for different groups of people, ranging from friends or parents to future employers. As part of the ‘This is Me’ project stories were collected from students and others about Digital Identity matters, a grounded methodological approach based on action research was used to establish issues related to Digital Identity particularly relevant to those in academia. Drawing from these issues, resources were developed to help inform and educate people about how they can understand and control their own Digital Identity. A number of these resources are presented here, along with reflections on how they are used and can be adapted.

Social network has gained remarkable attention in the last decade. Accessing social network sites such as Twitter, Facebook LinkedIn and Google+ through the internet and the web 2.0 technologies has become more affordable. People are becoming more interested in and relying on social network for information, news and opinion of other users on diverse subject matters. The heavy reliance on social network sites causes them to generate massive data characterised by three computational issues namely; size, noise and dynamism. These issues often make social network data very complex to analyse manually, resulting in the pertinent use of computational means of analysing them. Data mining provides a wide range of techniques for detecting useful knowledge from massive datasets like trends, patterns and rules [44]. Data mining techniques are used for information retrieval, statistical modelling and machine learning. These techniques employ data pre-processing, data analysis, and data interpretation processes in the course of data analysis. This survey discusses different data mining techniques used in mining diverse aspects of the social network over decades going from the historical techniques to the up-to-date models, including our novel technique named TRCM. All the techniques covered in this survey are listed in the Table.1 including the tools employed as well as names of their authors.
