Making Cognitive Niches Explicit: On the Importance of External Cognitive Representations in Accounting for Cumulative Culture.

Cumulative transmission and innovation are the hallmark properties of the cultural achievements of human beings. Cognitive scientists have traditionally explained these properties in terms of social learning and creativity. The non-social cognitive dimension of cumulative culture, the so-called technical reasoning, has also been accounted for recently.

Needle Trap Device-GC-MS for Characterization of Lung Diseases Based on Breath VOC Profiles.

Volatile organic compounds (VOCs) have been assessed in breath samples as possible indicators of diseases. The present study aimed to quantify 29 VOCs (previously reported as potential biomarkers of lung diseases) in breath samples collected from controls and individuals with lung cancer, chronic obstructive pulmonary disease and asthma. Besides that, global VOC profiles were investigated.

Professional mathematicians do not differ from others in the symbolic numerical distance and size effects.

The numerical distance effect (it is easier to compare numbers that are further apart) and size effect (for a constant distance, it is easier to compare smaller numbers) characterize symbolic number processing. However, evidence for a relationship between these two basic phenomena and more complex mathematical skills is mixed. Previously this relationship has only been studied in participants with normal or poor mathematical skills, not in mathematicians.

Dignity Therapy as an aid to coping for COPD patients at their end-of-life stage.

Introduction: Observations indicate that struggling with a burden of an incurable disease such as advanced chronic obstructive pulmonary disease (COPD) may result in the weakening of an individual sense of dignity, and be a source of spiritual suffering. Clinicians providing respiratory care to patients should be open to their spiritual needs, in the belief it may improve coping with the end-of-life COPD. The study aimed to assess overall feasibility and potential benefits of Dignity Therapy (DT) in patients with advanced COPD.
