Adolescents experience myriad emotions which occur in relation to their immediate social space which may shape their perceptions of members within the microsystem. The photovoice method uniquely provides participants with the means to capture their life through the lens of a camera while also enabling them to express emotions and meanings they attach to their particular life situations. We explore the various emotions adolescents attach to the spaces they occupy and how they link them to socialization in the context of the microsystem. This study was conducted in rural and urban areas of Udupi taluk, southern India. A total of 21 participants, ranging from early to late adolescence participated and provided multiple forms of data with 112 photographs, 21 journals on their daily interactions and one-on-one interviews facilitated using the SHOWeD model. The analytical method involved compiling visual data from photographs, journal content and interview data pertaining to each participant as a single data file, developing codes using ATLAS.ti, version 8, and further developing sub-themes and themes as they emerged into narratives. Our study was able to elicit emotions and meanings that adolescents attached to social interactions with gendered nuances specific to the Indian cultural setting. Future applications of the photovoice methodology on research among adolescents have also been discussed.

BACKGROUND: Exploring the cultural context of intergenerational continuity of warm and harsh parenting informs parents motivations to adopt specific parenting behaviours.
OBJECTIVE: Parents' perceptions of being parented in the past and their current parenting as well as adolescents' perceptions of current parenting were explored applying a multi-method approach.
METHODS: Following written informed consent, a total of 24 interviews with 10 families (dyads of 14 parents and ten adolescents) from Udupi taluk in southern India was conducted. In the first stage, in-depth interviews were conducted with parent participants (Generation 1 (G1)) and in the second stage, adolescents (Generation 2 (G2)) participated in the photovoice component. Multiple forms of data including photographs, journals and interviews facilitated using the SHOWeD model were collected and were analysed thematically using ATLAS.ti(v.8).
RESULTS: Subtle changes in reinforcing culture-specific gender norms between generations were elicited. Differences in communication, granting autonomy to female adolescents, and in disciplining methods between G1 and G2 were observed. Warm parenting was transmitted between generations while harsh parenting in G1 in the presence of external social support was discarded in favor of warm parenting in G2.
CONCLUSION: We provide evidence for perceptions of parenting and adolescent behaviors across two generations. Transmission of warm parenting and interruption in the cycle of harsh parenting in the presence of external social support were significant findings. Related theoretical and methodological applications are discussed.
Strategies for the Construction of Cassava Brown Streak Disease Viral Infectious Clones

Cassava brown streak disease (CBSD) has major impacts on yield and quality of the tuberous roots of cassava in Eastern and Central Arica. At least two Potyviridae species cause the disease: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). Cloned viral genome sequences known as infectious clones (ICs) have been important in the study of other viruses, both as a means of standardising infectious material and characterising viral gene function. IC construction is often technically challenging for Potyviridae due to sequence instability in E. coli. Here, we evaluate three methods for the construction of infectious clones for CBSD. Whilst a simple IC for in vitro transcription was made for UCBSV isolate 'Kikombe', such an approach failed to deliver full-length clones for CBSV isolates 'Nampula' or 'Tanza', necessitating more complex approaches for their construction. The ICs successfully generated symptomatic infection in the model host N. benthamiana and in the natural host cassava. This shows that whilst generating ICs for CBSV is still a technical challenge, a structured approach, evaluating both in vitro and in planta transcription systems should successfully deliver ICs, allowing further study into the symptomology and virulence factors in this important disease complex.
Evidence for the Higgs Boson Decay to a Z Boson and a Photon at the LHC

The first evidence for the Higgs boson decay to a Z boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision datasets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb^{-1} for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is 2.2±0.7 times the standard model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.
Combination of Measurements of the Top Quark Mass from Data Collected by the ATLAS and CMS Experiments at sqrt[s]=7 and 8 TeV

A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The datasets used correspond to an integrated luminosity of up to 5 and 20 fb^{-1} of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. The combination includes measurements in top quark pair events that exploit both the semileptonic and hadronic decays of the top quark, and a measurement using events enriched in single top quark production via the electroweak t channel. The combination accounts for the correlations between measurements and achieves an improvement in the total uncertainty of 31% relative to the most precise input measurement. The result is m_{t}=172.52±0.14(stat)±0.30(syst) GeV, with a total uncertainty of 0.33 GeV.
