Using Bayes Factors to Test Hypotheses in Developmental Research

This article discusses the concept of Bayes factors as inferential tools that can serve as an alternative to null hypothesis significance testing in the day-to-day work of developmental researchers. A Bayes factor indicates the degree to which data observed should increase (or decrease) the credibility of one hypothesis in comparison to another. Bayes factor analyses can be used to compare many ty

Selfiekulturen i sociala medier

Fotograferandet är en av alla de otaliga praktiker som i grunden har förändrats med digitaliseringen och de sociala medierna. Tidigare fotograferade folk företrädesvis i samband med högtider och semesterresor och bilderna hamnade i det privata familjealbumet. Idag bär vi ständigt med oss kameran i mobiltelefonen och knäpper bilder som aldrig förr, vilket har lett till en ”avsakralisering” och ett

Agnostus pisiformis — a half a billion-year old pea-shaped enigma

The Cambrian arthropod Agnostus pisiformis (Wahlenberg, 1818) is not only a beautiful fossil animal, approximately 1 cm in length when adult, but also an extinct species unusually well-known from its ‘soft’ ventral cuticular structures. It is moreover very useful for biostratigraphic correlation and has a long research history. The species occurs in huge numbers, and in all developmental stages, i

Quantification of l-carvone in toothpastes available on the Swedish market

Background: Toothpastes have widespread use in the population, and contain flavours to give a pleasant and often minty aroma. Flavours are prevalent allergens in toothpastes, and adverse reactions often present as perioral dermatitis or stomatitis. l-Carvone, a mint flavour found in spearmint oil, is one of these allergens. There are few studies on contact allergy to l-carvone, and some of them ha

Field data and simulations to estimate the role of standby energy use of lighting control systems in individual offices

This paper investigates the effectiveness of lighting control systems (LCSs) in 57 individual office rooms of an educational building located in Lund, Sweden. The study uses simulations based on actual occupancy data. The simulations, performed with Daysim via the Honeybee interface, focus on the portion of standby energy use on total lighting energy use considering different combinations of LCSs

Parmelia Ach. s. str. in the southern Baltic region

The distinguishing morphological and chemical characters of nine species of Parmelia Ach. s. str. occurring in the southern Baltic region, namely P. barrenoae Divakar et al., P. ernstiae Feuerer & A. Thell, P. fraudans (Nyl.) Nyl., P. omphalodes (L.) Ach. (including both subspecies P. omphalodes ssp. discordans (Nyl.) Skult and P. omphalodes ssp. omphalodes, P. pinnatifida Kurok., P. saxatilis

Sailing through marketing : A critical assessment of spatiality in marketing literature

Marketing has historically been entangled with the study of geography, which has become a very popular focus in the marketing literature nowadays. However, spatially-oriented perspectives in marketing tend to rest on a conceptual divide between place-oriented and space-oriented thinking, thus inhibiting the production of more eclectic and creative spatial knowledge. This conceptual paper endeavors

Children with respiratory tract infections in Swedish primary care; prevalence of antibiotic resistance in common respiratory tract pathogens and relation to antibiotic consumption

Background: The majority of antibiotics consumed in developed countries are prescribed in primary care. However, little is known about resistance levels in the primary care population. Method: Nasopharyngeal cultures were obtained from children, 0-10 years of age, seeking care at their Primary Health Care Centre with symptoms of respiratory tract infection. Parental questionnaires were used to ret

Accessing the gluon Wigner distribution in ultraperipheral pA collisions

We propose to constrain the gluon Wigner distribution in the nucleon by studying the exclusive diffractive dijet production process in ultraperipheral proton-nucleus collisions (UPCs) at the RHIC and the LHC. Compared to the previous proposal in Ref. [Y. Hatta, B. W. Xiao, and F. Yuan, Phys. Rev. Lett. 116, 202301 (2016).PRLTAO0031-900710.1103/PhysRevLett.116.202301] to study the same observable i

Correlation between edge radius of the cBN cutting tool and surface quality in hard turning

cBN cutting tools with superior mechanical properties are widely used in machining various hard materials. The microgeometry of cBN cutting tools, such as the edge radius, has great influence on the surface quality of components and tool life. For optimized tool geometry, it is crucial to understand the influence of the cBN cutting tool microgeometry on the machined surface quality. In this study,

Konversationer om humorns betydelse

Samtal mellan Anders Mortensen och Daniel Möller en eftermiddag i slutet av augusti 2017, vid en mikrofon på Språk- och litteraturcentrums café i Lund, med utgångspunkt i Gunnar Ekelöf, Dikter i Grönköpings Veckoblad. Utgivna med en inledning och kommentarer av Daniel Möller (2016) och de nya rön som Möller nu framlägger i Rethinking Scandinavia

Brev till en avsomnad vän : om erfarenhetens tänkande

Catharina Stenqvist (1950–2014) verkade som religionsfilosof med intresse för frågor om religiös erfarenhet och människans existentiella villkor. Hennes forskning kretsade kring mystik och mening och hon argumenterade för vikten att tala om livshållning snarare än livsåskådning. I föreliggande essä läser Patrik Fridlund en kort och lite annorlunda text av henne. I sitt efterord till denna essä skr

Sensescapes fascilitating life quality

What can be done to raise awareness of the significance of sense- and soundscape for health, wellbeing and communication? A massive body of research is being conducted in the sound environment field today with important discoveries especially on relationship between noise and health. Outcomes of this research slowly pours up into society, raising warnings of health and environmental risks, not sel

On the standardization of fitness and traits in comparative studies of phenotypic selection

Comparisons of the strength and form of phenotypic selection among groups provide a powerful approach for testing adaptive hypotheses. A central and largely unaddressed issue is how fitness and phenotypes are standardized in such studies; standardization across or within groups can qualitatively change conclusions whenever mean fitness differs between groups. We briefly reviewed recent relevant li

Rituximab in clinical practice : dosage, drug adherence, Ig levels, infections, and drug antibodies

The objective of this study is to explore the following: (1) the impact of two different initial doses and cumulative 2-year dose of rituximab (RTX) on drug adherence and predictors of adherence to treatment in rheumatoid arthritis (RA) patients in an observational clinical setting, (2) immunoglobulin levels (IgG/IgM/IgA) during repeated treatment and their relation to infections, and (3) developm
