This article took as its main objective to analyze the use of the internet by young students of 6th junior high education unit Cardenal Maurer, identify the types of social networks and influence in their lives, so knowing the consequences that affect in the teaching-learning process during training. To this end document review data and quantitative and qualitative techniques were used.

Samuel Shirley's splendid new translation, with critical annotation reflecting research of the last half-century, is the only edition of the complete text of Spinoza's correspondence available in English. An historical-philosophical Introduction, detailed annotation, a chronology, and a bibliography are also included.

A case-study of the interaction between philosophical context and observational data in the practice of Science.

Ethical decision-making is essential to professionalism in engineering. For that reason, ethics is a required topic in an ABET approved engineering curriculum and it must be a foundational strand that runs throughout the entire curriculum. In this paper the curriculum approach that is under development at the Padnos School of Engineering (PSE) at Grand Valley State University will be described. The design of this program draws heavily from the successful approach used at the service academies — in particular West Point (...) and the United States Naval Academy. As is the case for the service academies, all students are introduced to the “Honor Concept” (which includes an Honor Code) as freshmen. As an element of professionalism the PSE program requires 1500 hours of co-op experience which is normally divided into three semesters of full-time work alternated with academic semesters during the last two years of the program. This offers the faculty an opportunity to teach ethics as a natural aspect of professionalism through the academic requirements for co-op. In addition to required elements throughout the program, the students are offered opportunities to participate in service projects which highlight responsible citizenship. These elements and other parts of the approach will be described. “Train up a child in the way he should go and when he is old he will not depart from it.” King Solomon. (shrink)

The value of argumentation in science education has become internationally recognised and has been the subject of many research studies in recent years. Successful introduction of argumentation activities in learning contexts involves extending teaching goals beyond the understanding of facts and concepts, to include an emphasis on cognitive and metacognitive processes, epistemic criteria and reasoning. The authors focus on the difficulties inherent in shifting a tradition of teaching from one dominated by authoritative exposition to one that is more dialogic, involving (...) small-group discussion based on tasks that stimulate argumentation. The paper focuses on how argumentation activities have been designed in school science. Examples of classroom dialogue where teachers adopt the frameworks/plans are analysed to show how argumentation processes are scaffolded. The analysis shows that several layers of interpretation are needed and these layers need to be aligned for successful implementation. (shrink)

With contributions from the fields of psychology, linguistics, cognitive neuroscience, attention, genetics, development, and neuropsychology divided into five themed sections, this new edition of The Oxford Handbook of Psycholinguistics is unparalleled in its breadth of coverage.

This volume covers the philosophical, historical, religious, and interpretative aspects of the ancient Guodian bamboo manuscripts which were disentombed in the Guodian Village in Hubei Province, China, in 1993. Considered to be the Chinese equivalent of the Dead Sea Scrolls, these manuscripts are archaeological finds whose importance cannot be underestimated. Many of the texts are without counterparts in the transmitted tradition, and they provide unique insights into the developments of Chinese philosophy in the period between the death of Confucius and (...) the writings of Mencius, and beyond. Divided into two parts, the book first provides inter-textual contexts and backgrounds of the Guodian manuscripts. The second part covers the main concepts and arguments in the Guodian texts, including cosmology and metaphysics, political philosophy, moral psychology, and theory of human nature. The thematic essays serve as an introduction to the philosophical significance and the key philosophical concepts/thought of each text contained in the Guodian corpus. Each chapter has a section on the implications of the texts for the received tradition, or for the purpose of comparing some of the text with the received tradition in terms of the key philosophical concepts as well as the reading and interpretation of the texts. The volume covers most of the texts inscribed on the 800-odd slips of the Guodian corpus dated to the fourth century BCE. (shrink)

The development and use of nanotechnology in the food industry have grown steadily. While visions for nanofood suggest that the applications will improve quality and safety, they are also controversial for several reasons including potential health risks coupled with difficulty in assessing low-dosage nanoparticle risks as well as values-based objections. In recent years, debate over nanofoods has sparked inquiry into factors that predict public attitudes and purchase intentions. Such studies have investigated the roles of demographics and sociographics, value predispositions toward (...) science and technology, preferences for natural products, trust in regulatory agencies, scientific knowledge, and media attention. This study assesses the role of each of these factors in shaping public attitudes toward nanofood and improves the predictive models by evaluating concepts from protection motivation theory. We find that incorporating threat and coping appraisals provides the best predictive models of public attitudes and intention to purchase nanofood products. (shrink)

Falls are a leading cause of serious injury and restricted participation among persons with stroke (PwS). Reactive balance control is essential for fall prevention, however, only a few studies have explored the effects of lesion characteristics (location and extent) on balance control in PwS. We aimed to assess the impact of lesion characteristics on reactive and anticipatory balance capacity, gait, and hemiparetic lower limb function, in PwS. Forty-six subacute PwS were exposed to forward, backward, right and left unannounced horizontal surface (...) translations in 6 increasing intensities, while standing. Fall threshold (i.e., perturbation intensity that results in a fall into the harness system) was measured. In addition, the Berg Balance Scale (BBS), 6 Minute Walk Test (6MWT) and Lower Extremity Fugl-Meyer (LEFM) were measured. Lesion effects were analyzed separately for left- and right-hemisphere damaged (LHD, RHD) patients, using voxel-based lesion-symptom mapping (VLSM). Our results show that voxel clusters where damage exerted a significant impact on balance, gait and lower-limb function were found in the corticospinal tract, in its passage in the corona radiata and in the posterior limb of the internal capsule. Additional significant impact was found to lesions affecting the putamen and the external capsule. Balance, gait, and hemiparetic lower limb function showed much overlap of the corresponding ‘significant’ voxel clusters. Test scores of RHD and LHD patients were affected largely by damage to homologous regions, with the LHD group showing a wider distribution of ‘significant’ voxels. The study corroborates and extends previous findings by demonstrating that balance control, gait, and lower limb function are all affected mainly by damage to essentially the same brain structures, namely - the corticospinal tract and adjacent structures in the capsular-putaminal region.

Crudely put, educational research is unethical when it misrepresents or misidentifies—and so betrays—its putative beneficiaries or the goods and values they hold dear. How can researchers guard against these vulnerabilities? While acknowledging the vulnerabilities of educational research to abuses of trust and representation, and that there is no Archimedean point from which to approach research into people’s practices, we defend a universalist conception of research ethics in education. This universalist conception is developed via an examination of a central debate in (...) feminism, contrasting Alcoff’s positionality, Caughie’s performative conception and Nussbaum’s universalist conception of feminism.

‘Unconscious bias happens by our brains making incredibly quick judgements and assessments without us realising. Biases are influenced by background, cultural environment and experiences and we may not be aware of these views and opinions, or of their full impact and implications. This article opposes this point of view by arguing that bias is not unconscious but is conscious and linked to Charles Mills’ ‘Racial Contract’ and its ‘epistemologies of ignorance’. These epistemologies emerge from what the Equality Challenge Unit calls (...) ‘our background, cultural environment and personal experience’. Asserting that racism stems from ‘unconscious bias’ diminishes white supremacy and maintains white innocence as a ‘will to forget’ institutional racism. In equality and diversity training ‘unconscious bias’ has become a performative act to move beyond racism through training to participate in a constructed ‘post-racial’ reality. The article argues that through decolonizing ‘unconscious bias’, ‘white fragility’ and ‘self-forgiveness’ we can begin to see hidden institutional whiteliness at the base of conscious bias. (shrink)

The stereotyped pattern of cell commitments during leech embryogenesis is described. The nature of cell commitments during segmentation differs significantly between leech and fruit fly. Despite the constancy of cell fate assignments in normal development, ablation experiments show that cell interactions are essential in setting some of these commitments. Interacting cells follow a positionally determined hierarchy of fate choices. For other cells, which appear to have fates fixed from birth, the possibility of determinative interactions between mother and daughter cells is (...) discussed. (shrink)

During embryogenesis, cell division must be spatially and temporally regulated with respect to other developmental processes. Leech embryos undergo a series of unequal and asynchronous cleavages to produce individually recognizable cells whose lineages, developmental fates and cell cycle properties have been characterized. Thus, leech embryos provide an opportunity to examine the regulation of cell division at the level of individual well‐characterized cells within a community of different types of cells. Isolation of leech homologues of some of the highly conserved regulators (...) of the cell division cycle, and characterization of their patterns of maternal and zygotic expression, indicate that the cell divisions of early leech embryos are regulated by cell type‐specific mechanisms. These studies with leech embryos contribute to the emerging appreciation of the diverse mechanisms by which animals regulate cell division during early development. (shrink)

This study examines how low-income African American mothers of children with sickle cell disease cope with the reproductive implications of having passed a genetic disease on to their children. Based on in-depth interviews with 29 African American mothers, I found that most mothers knew about SCD prior to having a child with the disease; many knew they were carriers of the sickle cell trait. In explaining why this knowledge did not lead them to alter their reproductive behaviors, mothers invoked a (...) theme of medical mismanagement; that is, they said the genetic screening programs for SCD did not provide them with enough medical knowledge about the disease. The implication that adequate knowledge about SCD would have affected their childbearing choices, however, is contradicted by their subsequent reproductive behaviors. I argue that the SCD diagnosis threatened motherhood, an important cultural value among low-income African American women, and that they protected their reproductive autonomy by obfuscating SCD medical knowledge.
