TL;DR: Recent advances in the field of upconversion nanomaterials have motivated us to initiate a thematic issue focusing on fundamental principles, synthetic strategies, materials characterization, broad applications, and a Department of Chemistry, National University of Singapore, Singapore 117543, Singapore.
Abstract: Photon upconversion through the use of lanthanide-doped materials has been the focus of a growing body of research in the fields of materials chemistry and physics for more than 50 years. The attraction of this field has been the ability to generate photons at shorter wavelengths than the excitation wavelength after laser stimulation. Despite its potential utility for a number of applications, photon upconversion has been primarily investigated in bulk glasses or crystalline materials. That situation dramatically changed in the mid-2000s, with the widespread research in the development of upconversion nanomaterials. As a unique class of optical materials, upconversion nanomaterials exhibit useful applications spanning from lighting to volumetric 3D displays to photovoltaics. Particularly, nanosized upconversion nanocrystals have proven valuable as luminescent labels for chemical and biological sensing with marked improvements in the sensitivity and versatility of the sensors. Recent advances in the field of upconversion nanomaterials have motivated us to initiate a thematic issue focusing on fundamental principles, synthetic strategies, materials characterization, broad applications, and a Department of Chemistry, National University of Singapore, Singapore 117543, Singapore.

TL;DR: The central theme of the interlaboratory study was to provide values to help harmonize lipids, lipid mediators, and precursor measurements across the community, and it was also initiated to stimulate a discussion regarding areas in need of improvement.

TL;DR: In this article, a positive association was found between authoritative parenting (higher scores on all three dimensions) and secure attachment, whereas negligent parenting predicted avoidant attachment, and a unique pattern of associations emerged between particular dimensions of parenting and each attachment style.
Abstract: Associations between parenting style and quality of child--mother attachment in middle childhood (n = 202; grades 4--6) and adolescence (n = 212; grades 7--11) were investigated. Participants rated warm involvement, psychological autonomy granting, and behavioural monitoring (Lamborn et al., 1991). Attachment orientation was assessed using the Network of Relationships Questionnaire (Furman & Buhrmester, 1985), Coping Styles Questionnaire (Finnegan et al., 1996), and Relationship Questionnaire (Bartholomew & Horowitz, 1991). Overall, a positive association was found between authoritative parenting (higher scores on all three dimensions) and secure attachment, whereas negligent parenting (lower scores on all three dimensions) predicted avoidant attachment. Moreover, a unique pattern of associations emerged between particular dimensions of parenting and each attachment style. Findings suggests that psychological autonomy may have important implications for children's views of self whereas warm parental invol...

TL;DR: For example, the authors take stock of the key attributes that constitute the relational turn in economic geography, and the implications that such a turn has for three analytical tensions: the structure agency debate, the macroversus micro-unit of analysis and the geographic scale of the analysis.
Abstract: For almost two decades, economic geography has become increasingly populated with texts concerned with the ways in which social interactions between economic agents have shaped the geography of economic performance. This literature has ranged from identifying the cultural norms or conventions underpinning social relations (Storper, 1995, 1997; Asheim and Isaksen, 1997; Cooke and Morgan, 1998) to documenting the geographic extent of these relations (Scott, 1988; Dicken et al., 2001; MacKinnon et al., 2002) to analysing how different socio-economic processes can generate similar landscapes of restructuring (e.g. Massey, 1984, 1995; Glasmeier, 2000). Likewise, it has looked to disciplines outside of economic geography, most notably economic sociology with Granovetter’s (1985) notion of embeddedness and Coleman’s (1988) social capital but also the work of institutional economists (e.g. Hodgson, 1988; Lundvall, 1988), to integrate the ‘social’ into economic analysis. As a whole, this tendency represents a theoretical orientation where actors and the dynamic processes of change and development engendered by their relations are central units of analysis – an orientation we term here a ‘relational turn’ in economic geography. In this introductory article, we take stock of the key attributes that constitute this ‘turn’ by examining the context in which it has emerged, and the implications that such a turn has for three analytical tensions: the structure agency debate, the macroversus micro-unit of analysis and the geographic scale of the analysis. The four papers included in this special theme issue speak to those tensions, and by so doing, contribute to our understanding of the present limitations and potentials of a relational approach as well as suggest new directions for research. Some of the key contributions (though most certainly, not all) are reviewed here.

TL;DR: The present findings, obtained under saline and amphetamine test conditions, provide the first detailed classification of adult rat 50-kHz USVs, and may advance the understanding of inter-rat communication and affective state.
Abstract: 50-kHz ultrasonic vocalizations (USVs) emitted by adult rats are heterogeneous; they occur over a wide frequency range, show varying degrees of frequency modulation, and appear to differ in their behavioral significance. However, they have not been extensively categorized. The main objective of this study was to identify subtypes of 50-kHz USVs emitted by adult rats and to determine how amphetamine (AMPH) or social testing condition affects their relative and absolute production rate and acoustic characteristics. A second objective was to determine the extent of individual differences in call rate, call subtype profile, and acoustic parameters (i.e., duration, bandwidth, and mean peak frequency). Adult male Long–Evans rats were administered systemic amphetamine (0.25–2 mg/kg, IP) and tested individually or with a cage mate for 20 min. Call categories were defined based on visual inspection of over 20,000 USV spectrograms. Surgical devocalization was performed on a subset of AMPH-tested rats in order to confirm the authenticity of call subtypes. Fourteen categories of 50-kHz USVs were recognized. Call subtypes were differentially affected by social context, AMPH dose, and time within session. In contrast, the acoustic characteristics of call subtypes were notably stable. Marked and stable inter-individual differences occurred with respect to overall 50-kHz call rate, acoustic parameters, and call profile. The present findings, obtained under saline and amphetamine test conditions, provide the first detailed classification of adult rat 50-kHz USVs. Consideration of 50-kHz USV subtypes may advance our understanding of inter-rat communication and affective state.
