Only a few information and communication technology (ICT) work-integrated learning (WIL) projects involving universities and Indigenous partners are being reported and very little is known about the approaches that are followed. This article reports on successful student work placements in Indigenous communities when codeveloping software for the community. We provide two case studies of projects which involved work-integrated learning students and researchers from a university, as well as researchers and practitioners from Indigenous communities in New Zealand and Fiji. Two independent app development projects were the central focus of the collaborations with these two communities including placement students. The article describes the learning and insights from these WIL projects and provides recommendations for creating successful WIL opportunities with Indigenous communities.

The exponential growth in the use of digital technologies and the availability of mobile software applications (apps) has been well documented over the past decade. Literature on the integration of mobile technology into higher education reveals an increasing focus on how mobile devices are used within the classroom environment, both physical and online, rather than on how mobile applications may be used for either teaching or the research process. Our study surveyed staff and higher degree research students at a New Zealand university using an online questionnaire to gain insight into the use of mobile apps for tertiary teaching and research, seeking information, particularly on which apps were used for which tasks and what obstacles hindered their use. The online survey used 29 questions and ran in 2016/2017. 269 participants completed the survey, nearly 20% of the potential sample. We found that mobile apps were used by academics and students for both teaching and research, primarily in the form of document and data storage and exchange, and communication. Very little app use was recorded for in-class activities (teaching) or in-field activities (research). Apps use resulted from personal motivation rather than institutional planning. Both students and academics reported that institutional support and flexibility would likely provide motivation and lead to increased app use for both research and teaching.

This article examines women's perceptions of and experiences with institutional norms in political science departments and their institutions. Conceptually, it builds on feminist institutionalism. Specifically, it examines the broad institutional norms, formal and informal, that define political science departments within their larger institutions, as well as potential avenues for change. I argue that a "critical mass" of women in academic departments and the presence of "critical actors" in departmental and university leadership positions sympathetic to the cause and powerful enough to implement change can bring about institutional reforms. To that end, I conducted a survey among 1,273 female PhD students and faculty members in political science departments across the United States. The survey questions revolve around women's perceptions of institutional gender norms, the way they are judged by them, their ability to have professional success under them, and their (or others') ability to change them. After discussing the survey results within the context of feminist institutional theory, I offer some conclusions about the positions of women in political science departments in the United States, the implications of this for the profession at-large, and some thoughts on avenues for future research on the issue.

The attraction of anthropophilic mosquitoes to human host cues, such as body odour and carbon dioxide, gradually increases during adult maturation. This acquisition of host-seeking behaviour correlates with age-dependent changes in odorant receptor (OR) transcript abundance and sensitivity of olfactory sensory neurons (OSNs). One OR gene of the human malaria vector, Anopheles coluzzii, AcolOR39, is significantly downregulated in mature females, and a cognate ligand of AcolOR39, sulcatone, a major component of human emanations, mediates the observed behavioural inhibition of newly emerged (teneral) females to human body odour. Knockout of AcolOR39, using CRISPR–Cas9 mutagenesis, selectively abolished sulcatone detection in OSNs, housed in trichoid sensilla. However, knockout of AcolOR39 altered neither the response rate nor the flight behaviour of teneral females in a wind tunnel, indicating the involvement of other genes, and thus a redundancy, in regulating the acquisition of host seeking in mosquitoes.

Within the software engineering community, deciding how to collect, store and use personal data has become about more than just understanding our users. This paper considers ethical data use that includes cultural considerations and data ownership rights. We discuss indigenous data sovereignty as a concept and how it potentially impacts technological solutions that gather personal data from users. We propose an extension to typical user-centred design processes, which we call participatory data design. This incorporates the use of frameworks and tools that specifically focus on managing data within the cultural context it is gathered from. We also present a specific example of how we have used this approach in the context of a data collection project from Māori workers in New Zealand forestry. We conclude with a discussion of the wider implications of this approach. [ABSTRACT FROM AUTHOR]

The text discusses the Russian invasion of Ukraine in 2022, which has resulted in a large-scale armed conflict, loss of life, displacement of millions of Ukrainian citizens, and widespread destruction. The war has raised numerous questions for political scientists, such as how it happened, its impact on great power politics and European cohesion, and its effects on food and energy security worldwide. The text also highlights the importance of studying the war's influence on political science and politics in general. The collection of articles included in the text examines various aspects of the conflict, including the role of regime type, Russian disinformation strategies, and the influence of football fans. Overall, the articles contribute to understanding the impact of the war on peace in Europe and the reshaping of political relations. [Extracted from the article]

Future anthropogenic climate change is predicted to impact sensory-driven behaviors. Building on recent improvements in computational power and tracking technology, we have developed a versatile climate-controlled wind tunnel system, in which to study the effect of climate parameters, including temperature, precipitation, and elevated greenhouse gas levels, on odor-mediated behaviors in insects. To establish a baseline for future studies, we here analyzed the host-seeking behavior of the major malaria vector mosquito, Anopheles gambiae sensu strico , to human odor and carbon dioxide (CO2), under tightly controlled climatic conditions, and isolated from potential background contamination by the presence of an experimenter. When presented with a combination of human foot odor and CO2 (case study I), mosquitoes engaged in faster crosswind flight, spent more time in the filamentous odor plume and targeted the odor source more successfully. In contrast, female An. gambiae s. s. presented with different concentrations of CO2 alone, did not display host-seeking behavior (case study II). These observations support previous findings on the role of human host-associated cues in host seeking and confirm the role of CO2 as a synergist, but not a host-seeking cue on its own. Future studies are aimed at investigating the effect of climate change on odor-mediated behavior in mosquitoes and other insects. Moreover, the system will be used to investigate detection and processing of olfactory information in various behavioral contexts, by providing a fine-scale analysis of flight behavior.

The article offers information on the comparative approaches to development politics; and also includes determination of the complexity of the decision-making process by the urban development projects.

The article analyzes whether case-study practitioners adopt the case-selection practices suggested by methodologists through meta-analysis of a sample of peer-reviewed journal articles that use case studies as either a qualitative or a mixed-methods research design.

This paper addresses several less-explored dimensions of current scholarship on globalisation, migration and transnationalism: north–south migration streams, the role of second-generation ‘heritage migrants’ and the importance of social capital within unequal transnational social fields. We compare two circuits of second-generation migrants, Turk-Germans and Turk-Americans, engaged in ‘intensive transnationalism’ having independently moved to reside in their parents’ homeland. Istanbul becomes the site of homeland return for these distinct streams of educated heritage migrants. Cross-national comparison of the children of the more stigmatised Turk-German ‘guest workers’ with the socially less salient Turk-Americans of middle-class backgrounds offers insight into the way class networks and national capital are distinctly leveraged by adult children with immigrant parents of distinct contexts of homeland exit.

Background Stem cells located in the centre of the shoot apical meristem are required for the repetitive formation of new organs such as leaves, branches and flowers. In Arabidopsis thaliana, the ZWILLE/PINHEAD/AGO10 (ZLL) gene encodes a member of the ARGONAUTE (AGO) protein family and is required to maintain shoot meristem stem cells during embryogenesis. In the Landsberg erecta (Ler) acession, ZLL is essential for stem cell maintenance, whereas in the Columbia (Col) accession its requirement appears masked by genetic modifiers. The genetic basis for this variation has remained elusive. Results To understand the impact of natural variation on shoot stem cell maintenance, we analysed 28 wild-type Arabidopsis accessions from around the world and show that ZLL function is essential for stem cell maintenance in accessions mainly originating from Germany, but is dispensable for accessions from other regions. Quantitative Trait Loci (QTL) mapping using Ler/Col recombinant inbred lines indicated that at least five genomic regions, referred to as FLETSCHE (FHE) 1-5, modify ZLL function in stem cell maintenance. Characterisation of Col zll near isogenic lines confirmed that the major QTL, FHE2, is preferentially maintained as a Ler allele in seedlings lacking stem cells, suggesting that this region harbours an important modifier of ZLL function. Comparison of torpedo-stage embryo expression profiles to QTL map data revealed candidate FHE genes, including the Arabidopsis Cyclophilin-40 homologue SQUINT (SQN), and functional studies revealed a previously uncharacterised role for SQN in stem cell regulation. Conclusions Different genetic backgrounds influence the role of ZLL in embryonic stem cell maintenance, suggesting that modifiers influenced by geographical factors or pedigree influence the trait. Of the five FHE loci influencing stem cell maintenance in Ler-0 and Col-0, FHE2 was the most prominent and was tightly linked to the SQN gene, which encodes a cofactor that supports AGO1 activity. SQN also shows variable embryonic expression levels between accessions and influenced ZLL-dependency in transgenic assays, confirming a key role in stem cell maintenance. Reduced SQN expression levels in Col-0 correlate with transposon insertions adjoining the transcriptional start site, which may also contribute to stem cell maintenance in other ZLL-independent accessions.

Since the fall of communism, democracy has come to be seen as the 'only game in town'- the only legitimate form of political system. Democracy is considered legitimate because it provides for individual rights and allows the people access to the resources of the state. If 'we the people' defines the limits of these entitlements, the next logical question is who are 'the people'? In contemporary developed states, the problem of diversity is most often framed as a problem of immigration; the arrival of new groups threatens both the presumed homogeneity of established nations and their democracy. We argue for a new conception of democracy, which takes into account the constructed nature of 'the people' that democracy empowers. This paper attempts to provide such an account by advocating a new understanding of the relationship between nationalism, citizenship, and democracy. [ABSTRACT FROM AUTHOR]

The Arabidopsis ARGONAUTE1 (AGO1) and ZWILLE/PINHEAD/AGO10 (ZLL) proteins act in the miRNA and siRNA pathways and are essential for multiple processes in development. Here, we analyze what determines common and specific function of both proteins. Analysis of ago1 mutants with partially compromised AGO1 activity revealed that loss of ZLL function reestablishes both siRNA and miRNA pathways for a subset of AGO1 target genes. Loss of ZLL function in ago1 mutants led to increased AGO1 protein levels, whereas AGO1 mRNA levels were unchanged, implicating ZLL as a negative regulator of AGO1 at the protein level. Since ZLL, unlike AGO1, is not subjected to small RNA-mediated repression itself, this cross regulation has the potential to adjust RNA silencing activity independent of feedback dynamics. Although AGO1 is expressed in a broader pattern than ZLL, expression of AGO1 from the ZLL promoter restored transgene PTGS and most developmental defects of ago1, whereas ZLL rescued only a few AGO1 functions when expressed from the AGO1 promoter, suggesting that the specific functions of AGO1 and ZLL are mainly determined by their protein sequence. Protein domain swapping experiments revealed that the PAZ domain, which in AGO1 is involved in binding small RNAs, is interchangeable between both proteins, suggesting that this common small RNA-binding domain contributes to redundant functions. By contrast, the conserved MID and PIWI domains, which are involved in 59-end small RNA selectivity and mRNA cleavage, and the non-conserved N-terminal domain, to which no function has been assigned, provide specificity to AGO1 and ZLL protein function.

Advanced tourist information systems should offer more than relatively static information about sights and places. Instead, semantically rich information about sights should be delivered to the mobile users. Furthermore, tourists should not be overwhelmed by a stream of superfluous data that are unrelated to their interest, location, and knowledge of a place. Personalization of the information delivery to each traveler, together with their travel history, is therefore crucial. This article presents the major design issues of the personalized Tourist Information Provider (TIP). TIP is a combination of an event-based system (EBS) and a location-based service (LBS) applied to a mobile environment. We discuss the lessons learned from developing its kernel using a semantic network of sight-related information and considering the travelers' interest and travel route, with emphasis on modeling decisions and their impact on the final system.

Semantic annotation is the process by which existing texts receive a mark-up that allows automatic identification of named entities (e.g., to distinguish between a turkey bird and the country Turkey). Manual annotation is useful both as stand-alone process in a domain-specific setting or as post-processing for automatic annotation algorithms. Development of most annotation tools strongly focuses on providing novel functionality — end-user evaluations of interface and user interaction are rare. This article reports on the results of a series of user studies executed to explore how non-expert users understand the process of enriching texts with semantic annotations. We find that these users can easily create simple semantic annotations (e.g., assigning concepts to text passages) but have difficulties understanding complex semantic annotations (e.g., assigning semantic identifiers to text passages). We present the results of three user studies on manual semantic annotation and discusses the lessons learned about both the semantic enrichment process and our methodology of exposing non-experts to semantic enrichment.

Geothermal springs are model ecosystems to investigate microbial biogeography as they represent discrete, relatively homogenous habitats, are distributed across multiple geographical scales, span broad geochemical gradients, and have reduced metazoan interactions. Here, we report the largest known consolidated study of geothermal ecosystems to determine factors that influence biogeographical patterns. We measured bacterial and archaeal community composition, 46 physicochemical parameters, and metadata from 925 geothermal springs across New Zealand (13.9-100.6 °C and pH < 1-9.7). We determined that diversity is primarily influenced by pH at temperatures <70 °C; with temperature only having a significant effect for values >70 °C. Further, community dissimilarity increases with geographic distance, with niche selection driving assembly at a localised scale. Surprisingly, two genera (Venenivibrio and Acidithiobacillus) dominated in both average relative abundance (11.2% and 11.1%, respectively) and prevalence (74.2% and 62.9%, respectively). These findings provide an unprecedented insight into ecological behaviour in geothermal springs, and a foundation to improve the characterisation of microbial biogeographical processes. Power et al. catalogue the microbial biodiversity and physicochemistry of around 1000 hotsprings across New Zealand, providing insights into the ecological conditions that drive community assembly in these ecosystems.

Stem cells are maintained in an undifferentiated state by signals from their microenvironment, the stem cell niche. Despite its central role for organogenesis throughout the plant's life, little is known about how niche development is regulated in the Arabidopsis embryo. Here we show that, in the absence of functional ZWILLE (ZLL), which is a member of the ARGONAUTE (AGO) family, stem cell-specific expression of the signal peptide gene CLAVATA3 (CLV3) is not maintained despite increased levels of the homeodomain transcription factor WUSCHEL (WUS), which is expressed in the organising centre (OC) of the niche and normally promotes stem cell identity. Tissue-specific expression indicates that ZLL acts to maintain the stem cells from the neighbouring vascular primordium, providing direct evidence for a non-cell-autonomous mechanism. Furthermore, mutant and marker gene analyses suggest that during shoot meristem formation, ZLL functions in a similar manner but in a sequential order with its close homologue AGO1, which mediates RNA interference. Thus, WUS-dependent OC signalling to the stem cells is promoted by AGO1 and subsequently maintained by a provascular ZLL-dependent signalling pathway. [ABSTRACT FROM AUTHOR]

Summary: A long-standing question in plants and animals is how spatial patterns are maintained within stem cell niches despite ongoing cell divisions. Here we address how, during shoot meristem formation in Arabidopsis thaliana, the three apical cell layers acquire stem cell identity. Using a sensitized mutant screen, we identified miR394 as a mobile signal produced by the surface cell layer (the protoderm) that confers stem cell competence to the distal meristem by repressing the F box protein LEAF CURLING RESPONSIVENESS. This repression is required to potentiate signaling from underneath the stem cells by the transcription factor WUSCHEL, maintaining stem cell pluripotency. The interaction of two opposing signaling centers provides a mechanistic framework of how stem cells are localized at the tip of the meristem. Although the constituent cells change, the surface layer provides a stable point of reference in the self-organizing meristem. [Copyright &y& Elsevier]
