Technological and methodological advances in remote sensing and machine learning have created new opportunities for advancing wildlife surveys. We assembled a Community of Practice (CoP) to capitalize on these developments to explore improvements to the efficiency and effectiveness of aerial wildlife monitoring from a management perspective. The core objective of the CoP is to organize the development and testing of remote sensing and machine learning methods to improve aerial wildlife population surveys that support management decisions. Beginning in 2020, the CoP collaboratively identified the natural resource management decisions that are informed by wildlife survey data with a focus on waterbirds and marine wildlife. We surveyed our membership to establish 1) what management decisions they were using wildlife count data to inform; 2) how these count data were collected prior to the advent of remote sensing/machine learning methods; 3) the impetus for transitioning to a remote sensing/machine learning methodological framework; and 4) the challenges practitioners face in transitioning to this framework. This paper documents these findings and identifies research priorities for moving toward operational remote sensing-based wildlife surveys in service of wildlife management.

Background: Business incubators (BIs) are considered enablers of the entrepreneurial ecosystem, however there remains a lack of consensus as to whether incubators are effective or even as to how incubator efficacy should be measured. Aim: This study seeks to develop a consolidated framework for measuring the efficacy of BIs using stakeholder theory as its theoretical basis. This study set out to answer the following research questions: What is the relevance of stakeholder theory to incubator efficacy measurement? What stakeholder groups are relevant to BIs in South Africa? What relationships between stakeholder groups and perspectives on BI efficacy exist that would underpin a framework for measuring incubator efficacy? Setting: Empirical research was conducted with BIs operating within South Africa, with various incubator types, contexts and industry focus included in the study. Methods: A sample of nine incubator managers were interviewed as part of this exploratory qualitative study, demonstrating the breadth of the incubator industry in South Africa. Results: A framework comprising two distinct but related perspectives on incubator efficacy is proposed. Further to this, two additional concepts – incubator-stakeholder conflict and restrictive incubator context – were identified. Conclusion: This study proposes a consolidated framework for measuring the efficacy of BIs, considering a variety of stakeholder perspectives, and may inform policymakers regarding business incubation in the future. Contribution: This study identifies and defines incubator-stakeholder conflict as a concept, making a theoretical contribution to the field. Additionally, the study proposes a comprehensive stakeholder-based framework proposed for measuring incubator efficacy.

Comparative studies suggest remarkable similarities among food webs across habitats, including systematic changes in their structure with diversity and complexity (scale-dependence). However, historic aboveground terrestrial food webs (ATFWs) have coarsely grouped plants and insects such that these webs are generally small, and herbivory is disproportionately under-represented compared to vertebrate predator–prey interactions. Furthermore, terrestrial herbivory is thought to be structured by unique processes compared to size-structured feeding in other systems. Here, we present the richest ATFW to date, including approximately 580 000 feeding links among approximately 3800 taxonomic species, sourced from approximately 27 000 expert-vetted interaction records annotated as feeding upon one of six different resource types: leaves, flowers, seeds, wood, prey and carrion. By comparison to historical ATFWs and null ecological hypotheses, we show that our temperate forest web displays a potentially unique structure characterized by two properties: (i) a large fraction of carnivory interactions dominated by a small number of hyper-generalist, opportunistic bird and bat predators; and (ii) a smaller fraction of herbivory interactions dominated by a hyper-rich community of insects with variably sized but highly specific diets. We attribute our findings to the large-scale, even resolution of vertebrate, insect and plant guilds in our food web. This article is part of the theme issue 'Connected interactions: enriching food web research by spatial and social interactions'. [ABSTRACT FROM AUTHOR]

Older first‐generation migrants living in Europe, particularly Turkish migrants, feel relatively lonely, which indicates social exclusion. Social embeddedness within the family, particularly parent‐child relationships, can alleviate loneliness for older migrants, but such relationships can also be ambivalent, which may not prevent loneliness altogether. Earlier research indicates that Turkish migrants in Germany report high quality relationships with their children and high levels of social support exchanges within the family; however, some still report disappointing aspects of the relationship with their children, such as feeling disrespected. To better understand these contradictory findings, this article focuses on various aspects of parent‐child relationships that may explain loneliness among older Turkish migrants in Germany. Moreover, the article considers whether filial expectations can be potential sources of intergenerational conflict that may explain higher levels of loneliness among older Turkish migrants. Using the Generations and Gender Survey with 606 first‐generation Turkish respondents aged 50 and above, findings show that having low satisfying relationships with children and not having adult co‐residing children is associated with more loneliness. Turkish migrants with higher filial expectations feel lonelier when they have good perceived health, and less lonely when they have bad perceived health. These findings indicate that especially healthy older Turkish migrants may have unfulfilled expectations regarding parent‐child relationships, which adds to their loneliness, while parents with bad health experience solidarity, which lowers their loneliness. This shows that both intergenerational solidarity and conflict influence loneliness among older Turkish migrants.

Objectives Moroccan and Turkish migrants residing in Northwestern Europe have high loneliness levels. This study examines gender differences in loneliness within this migrant population. The migrants have gender-segregated social roles at home and in public, which might lead to gender differences in what aspects of social relationships can explain variation in loneliness. Methods Respondents are from the Longitudinal Aging Study Amsterdam with 446 first-generation Moroccan and Turkish migrants in the Netherlands, aged between 55 and 66 years. We use interaction effects to test for gender differences in determinants of loneliness. Results Men and women have a similar, moderate level of loneliness. Having a spouse and receiving care from children are more strongly related with lower loneliness levels in men than in women. Coethnic ties play an equally important role for men and women. In men, frequent mosque attendance is related with greater loneliness, but not in women. Discussion Family ties are more protective against loneliness for older men than for older women, possibly indicating that migrant women's expectations regarding family go above and beyond having a spouse, receiving intergenerational care, or having frequent contact with children. In addition, migrant older men's higher expectations regarding a public social life could make their social life in the Netherlands less fulfilling, resulting in greater loneliness.

This paper interrogates international and domestic peer relations in two Australian schools and how they are shaped by structural, cultural and discursive dimensions of schooling. In particular, it analyses intercultural relations between domestic and international students in the context of policies promoting "internationalisation-at-home". We argue that how international students are positioned within specific school contexts impacts their sense of inclusion in everyday social and pedagogical relations and informs their relationships with domestic students, whether viewed as a stranger or potentially as a friend raising questions as to who is responsible for intercultural relations.

Drought intensity and duration are expected to increase over the coming century in the semiarid western United States due to anthropogenic climate change. Historic data indicate that megadroughts in this region have resulted in widespread ecosystem transitions. Landscape-scale monitoring with remote sensing can help land managers to track these changes. However, special considerations are required: traditional vegetation indices such as NDVI often underestimate vegetation cover in semiarid systems due to short and multimodal green pulses, extremely variable rainfall, and high soil fractions. Multi-endmember spectral mixture analysis (MESMA) may be more suitable, as it accounts for both green and non-photosynthetic soil fractions. To determine the suitability of MESMA for assessing drought vegetation dynamics in the western US, we test multiple endmember selection and model parameters for optimizing the classification of fractional cover of green vegetation (GV), non-photosynthetic vegetation (NPV), and soil (S) in semiarid grass- and shrubland in central New Mexico. Field spectra of dominant vegetation species were collected at the Sevilleta National Wildlife Refuge over six field sessions from May–September 2019. Landsat Thematic Mapper imagery from 2009 (two years pre-drought), and Landsat Operational Land Imager imagery from 2014 (final year of drought), and 2019 (five years post-drought) was unmixed. The best fit model had high levels of agreement with reference plots for all three classes, with R2 values of 0.85 (NPV), 0.67 (GV), and 0.74 (S) respectively. Reductions in NPV and increases in GV and S were observed on the landscape after the drought event, that persisted five years after a return to normal rainfall. Results indicate that MESMA can be successfully applied for monitoring changes in relative vegetation fractions in semiarid grass and shrubland systems in New Mexico.

The chemoselective reduction of diaryl imines in the presence of competitively reducible groups is uniquely accessed through precise control of reaction and irradiation time by continuous flow visible light photoredox catalysis. The method enables the mild and efficient transfer hydrogenation of diaryl imines in the presence of sensitive functionality including halides, ester, ketone, and cyano groups. The flow protocol is efficient, rapid (>98% conversion within 9 min) and readily scaled to deliver multigram quantities of amine products in high purity.

Examines the effects of teacher race, pupil race, and teacher-child racial congruence on teacher ratings of the school adjustment of 445 kindergarten through fifth-grade children from 70 classrooms in 24 racially mixed urban schools. The relation between stereotypic teacher views and other adjustment indicators was consistently higher for African American children than for White children. (Author/MKA)

Anaplastic large cell lymphoma with a small cell pattern is a rare T-cell lymphoma. This condition is more frequently seen in younger patients and should be considered when patients present with leucocytosis and constitutional symptoms. In this report, we describe our diagnostic work-up for one such case using blood, lymph node, and bone marrow aspirate samples, highlighting the variability of antigen expression seen in different sample types and methodologies. This case shows the importance of having a high index of suspicion and assessing CD30 and anaplastic lymphoma kinase expression in all suspected T-cell neoplasms even though this rare condition is not necessarily expected.
