Writing over a century ago, Darwin hypothesized that vocal expression of emotion dates back to our earliest terrestrial ancestors. If this hypothesis is true, we should expect to find cross-species acoustic universals in emotional vocalizations. Studies suggest that acoustic attributes of aroused vocalizations are shared across many mammalian species, and that humans can use these attributes to in

The spontaneous crafting of hook-tools from bendable material to lift a basket out of a vertical tube in corvids has widely been used as one of the prime examples of animal tool innovation. However, it was recently suggested that the animals' solution was hardly innovative but strongly influenced by predispositions from habitual tool use and nest building. We tested Goffin's cockatoo, which is nei

Head turning experiments are widely used to test the cognition of both human infants and non-human animal species. Monitoring head turns allows researchers to non-invasively assess attention to acoustic or visual stimuli. In the majority of head turning experiments, the head direction analyses have been accomplished manually, which is extremely labor intensive and can be affected by subjectivity o

Documentation and emotions. Balancing paper work and emotional work in the social services This article deals with documentation and documentation requirements in relation to social workers’ prerequisites to perform ”emotional labour”. Inspired by Arlie Hochschild’s sociology of emotions and the selected concepts emotional labour, feeling management and ”the speed-up”, the study aims at illuminati

The Bit Flipping algorithm is a hard decision decoding algorithm originally designed by Gallager in 1962 to decode Low Density Parity Check Codes (LDPC). It has recently proved to be much more versatile, for Moderate Parity Check Codes (MDPC) or Euclidean metric. We further demonstrate its power by proposing a noisy Euclidean version of it. This tweak allows to construct a lattice based key exchan

Investigating how international market actors create market morality on a global level, this book reflects on the unresolved questions and debates regarding the relationship between business and society. The author explores how market actors in international business communication are unified in their attempts to make markets moralised. Providing detailed case studies and empirical evidence based

We look at the link between the volatility in the Bitcoin market and the volatility in other related traditional markets, i.e. the gold, currency and stock market. We also try to answer if the volatility in the Bitcoin market can be explained by retail investor-driven internet search volumes or, perhaps, by the general level of risk in the financial system, as measured by two market-wide risk indi

Every year thousands of refugees are resettled to dozens of host countries. While there is growing evidence that the initial placement of refugee families profoundly affects their lifetime outcomes, there have been few attempts to optimize resettlement destinations. We integrate machine learning and integer optimization technologies into an innovative software tool that assists a resettlement agen

European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation.The scope of this thesis is to explore other ways of reducing NOx emissions emittedby a heavy-duty engine. Several technology options are

Lacking secure attachment representations is associated with vulnerability to mental and physical health problems, perhaps mediated by increased susceptibility to stress and impaired emotion regulation. Even though cognitive representations of self and others tend to favor confirmation over information, research has shown that adult attachment security can be positively influenced. In a randomized

OBJECTIVE: Small airway disease and chronic obstructive pulmonary disease are common in primary Sjögren's syndrome (pSS). However, the underlying inflammatory mechanisms behind pSS-associated airway disease have not been studied in detail. We therefore wanted to study cytokine and leucocyte levels in induced sputum in never-smoking patients with pSS.METHOD: Induced sputum cytokines and leucocytes

We study the intergenerational social mobility of women by looking at how migration was associated with socioeconomic marriage mobility using complete-count census data for Sweden. The censuses 1880–1900 have been linked at the individual level, enabling us to follow almost 100,000 women from their parental home to their new marital household. Marriage market imbalances were not an important push
