Purpose Some empirical evidence suggests that historically marginalized young people may enter introductory programming experiences with skepticism or reluctance, because of negative perceptions of the computing field. This paper aims to explore how learner identity and motivation can affect their experiences in an introductory computer science (CS) experience, particularly for young people who have some prior experience with computing. In this program, learners were asked to develop digital media artifacts about civic issues using Scratch, a block-based programming language. Design/methodology/approach Through participant observation as a teacher and designer of the course, artifact analysis of student-generated computer programs and design journals, as well as with two follow-up 1-h interviews, the author used the qualitative method of portraiture to examine how two reluctant learners experienced a six-week introductory CS program. Findings These learners’ experiences illuminate the ways in which identity, community and competence can play a role in supporting learner motivation in CS education experiences. Research limitations/implications As more students have multiple introductory computing encounters, educators need to take into account not only their perceptions of the computing field more broadly but also specific prior encounters with programming. Because of the chosen research approach, the research results may lack generalizability. Researchers are encouraged to explore other contexts and examples further. Practical implications This portrait highlights the need for researchers and educators to take into account student motivation in the design of learning environments. Originality/value This portrait offers a novel examination of novice programmer experiences through the choice in method, as well as new examples of how learner identity can affect student motivation.

Background: Screening and monitoring serum bilirubin (SBR) in neonates is crucial to prevent neonatal hyperbilirubinemia (NH)-associated morbidity and mortality worldwide. A lack of resources is often a barrier for measuring SBR in developing countries. Reliable, cost-effective, easy to use point-of-care (POC) SBR tests are needed. This study aimed to evaluate the technical accuracy and usability of the Bilistick System (BS), a new bilirubin POC test, in a tropical setting. Methods: This was a mixed-methods study, including laboratory validation of the BS, direct observation of technical procedures as performed by the midwives and midwives’ assessment of the device’s easiness of use through focus group discussions (FGD) and a self-administered questionnaire. The study was conducted in a field clinic of the Shoklo Malaria Research Unit along the Thailand-Myanmar border between January and December 2017. Results: A total of 173 samples were tested at a median age of 4 days. BS generated an error message—providing no SBR readout—in 48.6% of the tests performed. For the tests that yielded a result, the correlation coefficient (95% CI) between BS and routine laboratory bilirubinometer SBR was 0.87 (0.77-0.93). The accuracy decreased with increasing haematocrit and at higher humidity (≥75%). Direct observation of the operators using the device and analysis of the focus group discussions and questionnaires indicated that the BS was considered easy to use and required limited training. Conclusions: This evaluation showed that the BS, in its current formulation, does not provide reliable results for measuring SBR in a tropical, low-resource setting  but has acceptable usability features.

Wireless networks are vulnerable to many security attacks as they use wireless media and a node has to depend on unknown intermediate nodes for data transmission. Cryptographic algorithms used for wired network cannot work efficiently in wireless network, as in wireless network nodes are mobile and battery operated. Nodes may also have limited resources available. So, to detect malicious activities on node and improve stability of route while routing in mobile ad hoc network, trust-based routing is used. Communication parameters used in calculating trust value in most of existing trust based protocol (wireless network) are number of successful session or packet forwarded between two nodes, number of packet dropped or delayed, response time, battery life, mobility of node etc. This paper provides analysis of existing trust based routing by surveying current “sate of the art” work in this area. This paper also proposed a new parameter (number of route error message sent by a node) of a wireless node which can affect the network performance and can be used to calculate trust value.
