Conifer growth and reproduction in urban forest fragments: Predictors of future responses to global change?

Global change has a large and growing influence on forests, particularly in urban and urbanizing areas. Compared to rural forests, urban forests may experience warmer temperatures, higher CO₂ levels, and greater nitrogen deposition, with exacerbated differences at urban forest edges. Thus, comparing urban to rural forests may help predict future effects of global change on forests. We focused on the conifer western red-cedar (Thuja plicata) to test three hypotheses: at urban forest edges, relative to rural forests and urban forest centers, trees experience 1) higher temperatures and nitrogen levels, 2) lower seedling recruitment, and 3) greater growth. We additionally tested anecdotal reports that 4) tree seedling recruitment in urban and rural forests is much lower than in ??pristine?? old-growth forests. To test these hypotheses, we quantified air temperature, soil nitrate, adult T. plicata growth and seedling recruitment in five urban and three rural parks at both forest edges and centers. We also quantified T. plicata recruitment at five old-growth ??pristine?? sites. Temperatures were highest at urban forest edges, and soil nitrate was highest in urban forests. In urban relative to rural forests, we observed greater T. plicata growth, but no difference in seedling densities. However, seedling densities were lower in urban and rural forests than in old-growth forests. In all, our results suggest urban influences enhance adult T. plicata growth, but not seedling recruitment. Recruitment in urban and rural forests was reduced compared to old-growth forests, implying that fragmentation and logging reduce T. plicata seedling recruitment.     

‘To talk or not to talk?’: Foster youth's experiences of sharing stories about their past and being in foster care

Sharing stories about the past and about being in care, can help adolescents placed in foster families to make meaning of their experiences and connect with their conversation partner. However, what obstacles and opportunities for sharing stories are experienced by foster youth has not been researched, while this holds important implications for research and practice. In an episodic interview, thirteen adolescents and young adults (16–23 years) talked about their experiences with sharing their memories about their past and being in foster care. Using a thematic analysis, two themes were constructed, each containing three sub-themes. The theme ‘When’ included references to the prerequisites for talking and considerations made by participants, and contained the sub-themes ‘How often do I talk’, ‘Conditions’ and ‘Ownership of my story’. The theme ‘Why’ included references to the rationales for sharing or not sharing memories, which contained the sub-themes ‘Protection’, ‘Understanding’ and ‘Processing the past’. The stories of the participants highlight both the opportunities and obstacles for talking. Foster parents and foster care workers should be aware of the needs foster youth have with regard to conversations about their experiences and should try to facilitate the meaning-making processes, although some foster youth prefer managing their memories in a more private way.     

Urban forest biomass estimates: is it important to use allometric relationships developed specifically for urban trees?

Many studies have analyzed the benefits, costs, and carbon storage capacity associated with urban trees. These studies have been limited by a lack of research on urban tree biomass, such that estimates of carbon storage in urban systems have relied upon allometric relationships developed in traditional forests. As urbanization increases globally, it is becoming important to more accurately evaluate carbon dynamics in these systems. Our goal was to understand the variability and range of potential error associated with using allometric relationships developed outside of urban environments. We compared biomass predictions from allometric relationships developed for urban trees in Fort Collins, Colorado to predictions from allometric equations from traditional forests, at both the individual species level and entire communities. A few of the equations from the literature predicted similar biomass to the urban-based predictions, but the range in variability for individual trees was over 300%. This variability declined at increasingly coarse scales, reaching as low as 60% for a street tree community containing 11 tree species and 10, 551 trees. When comparing biomass estimates between cities that implement various allometric relationships, we found that differences could be a function of variability rather than urban forest structure and function. Standardizing the methodology and implementing averaged equations across cities could be one potential solution to reducing variability; however, more accurate quantification of biomass and carbon storage in urban forests may depend on development of allometric relationships specifically for urban trees.     

Do Sons or Daughters Give More Money to Parents in Urban China?

The patriarchal structure of the traditional Chinese family suggests that sons, more than daughters, provide financial support to elderly parents. The norm of receiving support in old age primarily from sons, however, may have been undermined by dramatic demographic, economic, and cultural changes occurring over the last several decades in China, especially in urban areas. We examine gender differences in adult children’s financial support to parents using a recent data set (“Study of Family Life in Urban China”) collected in 1999 (N = 1,801). The results show that married daughters, especially those living with parents, provide more financial support to parents than married sons do. This significant gender difference can be primarily explained by daughters’ resources, such as education and income.     

Do trees flower longer in the city? A comparison of flowering eucalyptus trees in streets,remnants and continuous forest and their association with nectarivorous birds

Human-dominated environments are often subjected to increased nutrient and moisture regimes which have the potential to influence the flowering phenology of plants. Protracted flowering periods within urban landscapes may result in increased food resources, in the form of nectar, and this high resource availability may support a high density of nectarivorous birds within cities. In order to determine whether there was a difference in the productivity and flowering period associated with urbanisation, we compared the number of flowers produced and duration of flowering period for three species of native tree that were present in streetscapes, remnant vegetation and continuous forest. We also recorded the presence of nectarivorous parrots at flowering trees to determine if the presence of nectarivores was associated with flower productivity. All three species in streetscapes produced more flowers and flowered for longer than in remnants and continuous forest. The number of flowers per tree significantly predicted the presence of nectarivorous parrots in streetscapes. This study demonstrates that the flowering phenology of plants within streetscapes can differ from continuous forest, with remnants appearing to be intermediate. This increased flower productivity within urban landscapes may be partially responsible for the high abundance of nectarivorous parrots within some cities.     

Do cows belong in nature? The cultural basis of agriculture in Sweden and Australia

Within the now extensive recent literature on cultures of nature, agriculture has received less attention than might have been expected given its threshold role in transforming human relations with the earth and with plants and animals. The concept and practice of agriculture can be understood as central to the emergence and maintenance of the culture/nature dichotomy within Western thought and practice. In this paper we use the comparative cases of Sweden and Australia to examine the differential and contingent positioning of agriculture with respect to that which is understood as nature. Broadly speaking, some parts of agriculture are understood to belong to nature in Sweden through a long history. This is not the case in Australia, where the short agricultural history is positioned in contrast to nature. This affects the way in which biodiversity and environmental protection takes place - in Sweden as part of farming, - in Australia in spite of it. We argue that these cultural differences have been more important than generally recognised in debates over multifunctional agriculture. We discuss the environmental management implications of the two different models in a context made more dynamic by climate change.     

Rural Community and Rural Resilience: What is important to farmers in keeping their country towns alive?

Many studies have highlighted the phenomenon of rural decline in parts of the developed world, summarised as a loss in agricultural employment leading to a decline in the number and size of rural settlements. This study of small towns in part of Australia’s inland rural “heartland” employs the concepts of interactional rural community of place and rural resilience to identify how farmers perceive their interactions with their local town. This study suggests that robust levels of ongoing engagement between farmers and town communities are important in maintaining rural populations and services along with both a strong local economy and environment. Face-to-face interviews with 115 farmers in two rural regions of New South Wales, Australia, highlight the importance of the local economy and jobs, the quality of the local environment and a strong sense of belonging, in contributing to a strong sense of local community and potential for resilience.     

Children's Engagement as Urban Researchers and Consultants in Aotearoa/New Zealand: Can it Increase Children's Effective Participation in Urban Planning?

Children conducting research and engaging in ‘adult’ domains such as urban planning challenge perceptions of children as merely ‘adult becomings’ — perceptions which, along with lack of pathways for participation, have largely excluded children from effective participation in the public realm. This paper considers two urban participatory projects in Aotearoa/New Zealand: in the first, children (10–13 years) researched peer perceptions of Auckland city life; in the second, they were consulted by Auckland Council on the redevelopment of a city square. We reflect on processes and outcomes, and the extent to which facilitating such projects may increase children's meaningful participation in urban planning.     

Back to the future? From pragmatic approaches in the social sciences to the development of the patchwork theory

The debate on the function of the social sciences in complex societies, and more generally of the role of knowledge, leads necessarily to a discussion on pragmatism. The gap between theoretical approaches and empirical research still exists and has even widened, in part as a result of the use and abuse of social science knowledge in politics and by the media. However, the academic system is equally to blame for this. Mutual ignorance and scholastic fights are barriers against openness, creative and imaginary thinking. The structures and the practices of the academic system reinforce this trend. Pragmatism aims at overcoming these cleavages by looking at commonalities between different approaches rather than by disputing their validity. It aims at a comprehensive understanding of the process of knowledge production and at the productive use of results. Defining itself in this tradition, the patchwork theory goes beyond the traditional pragmatic approaches: it catches part of the reality of social phenomena from a certain perspective that allows for an overview without having the full picture. Methodologicall, the approach guided by patchwork theory emphasizes the relevance of stakeholders’ knowledge and citizen science, and calls for public participation and democratic access to the production and use of knowledge in a discursive manner.     

‘Back to our Roots?’ Re-visiting psychoanalytically-informed baby and young child observation in the education of student social workers

While there is a well-established literature on psychoanalytically-informed baby and young child observation in social work education, little has been published recently. This paper reviews the rationale for its use, evaluating its impact on students’ learning in the light of contemporary policy and practice contexts facing social work education. Analysis of feedback gained from a recent cohort, identifies three ways in which learning through baby and young child observation contributes: firstly, students encounter and learn about the complexity of child development from the direct experience of observing and secondly, observing facilitates the development of important skills for practice; students’ ‘use of self’. Thirdly, through observing, students describe how they develop the capacity to take-up and sustain a professional role. Well-structured teaching and learning through observation is therefore shown to provide a rigorous, theoretically-grounded contribution to the training of university-based social work students entering this complex and challenging professional field.     

Opting in to Opt out? Emigration and Group Participation in Albania

The objective of this paper is to determine whether the participation in social organizations represents a complement or a substitute with respect to international emigration. To address this research question, an instrumental variable approach is used, as group participation and international migration are potentially jointly determined. This is the case if the family considers emigration and group participation as alternative strategies to cope with uncertainty or a liquidity need, or alternatively when the family decides to invest in group participation in order to gain information helpful to emigrate. The results of the empirical estimation reveal that families participating in social organizations are more likely to migrate internationally and therefore social networks act as a complement for emigration. This may indicate that families recourse to social networks in order to collect important information that facilitates international migration.     

Enduring not enjoying? Emotional responses to studying abroad among Danish and Chinese students

ABSTRACT

Students’ emotions during stays abroad have mainly been treated as ”culture shock”, where difficulties are interpreted as universal ”stages” towards ”adaptation”. This paper explores how students from different cultural and educational traditions experience studying abroad differently. The study presents a qualitative study of 18 Danish and Chinese students in Chinese and Danish universities and situates itself within the literature on culture shock, student emotions and study-abroad experiences. The study exposes the students’ complex emotions throughout their studies abroad and explains how these emotions relate to processes of self-formation, professional and academic development, increase or decrease in freedom, and student agency.     

What factors attract and motivate dairy farm employees in their daily work?

This study examined attraction and motivation factors important for people choosing to work and remain in the profession of dairy farm worker. The study comprised 194 agricultural students, 197 employed dairy farm workers and 147 employers. The study was based on questionnaires in which the key questions were: What would attract you to choose dairy farming as a profession? What attracts and motivates you in your daily work? What would motivate you to remain employed in dairy farming? Furthermore, in order to elucidate the farm employer's view, they were asked what they believed were important factors to attract and motivate young people to the profession. In general, the students, employees and employers had similar opinions on factors that attract and motivate dairy farm workers in their daily work. Although the order of priorities was different, they agreed that having fun at work, good leadership, feeling pride in their work, job security, good team spirit, living in the countryside, meaningful and interesting work, safe and healthy workplace, flexible work tasks, the farm having a good reputation and feedback from supervisors were among the most important attraction and motivation factors.     

Why Do Immigrants and Refugees Give Back to Their Communities and What can We Learn from Their Civic Engagement?

Each year thousands of immigrants and refugees begin their lives in new places, speaking new languages, and facing new challenges. Challenges include access to health/mental care, education, transportation, and employment. Researchers and practitioners frequently focus on challenges of newcomers and their deficits in meeting needs for self-sufficiency. This study explores newcomers’ giving back and emphasizes an untapped reservoir of strength and capacity. Based on qualitative semi-structured interviews with 54 immigrants and refugees, themes identified include (1) a desire to maintain ethnic identity and connection; (2) ethnic community as an extension of family; (3) a sense of duty and obligation; and (4) measure of achieved success. Researchers and practitioners should shift their view to recognize the strengths and capacities of newcomers who give back to their communities.     

‘How dare you pretend to be disabled?’ The discounting of transabled people and their claims in disability movements and studies

Although the contours of the ‘disabled person’ category are questioned by anti-ableist activists, they remain rigid regarding transabled people (who want to become disabled). For anti-ableist activists, transabled people do not count as disabled. They are perceived to: be falsely disabled; steal resources from disabled people; and be disrespectful by denying, fetishizing, or appropriating marginalized realities. By combining critical discourse analysis, genealogy, and deconstruction, I examine these negative discourses to encourage alliances between anti-ableist activists and transabled people. Ideas developed in disability and trans studies reveal the limits of these discourses anchored in ableist and cisnormative* assumptions.

To meet or not to meet? Measuring motivations and risks as predictors of outcomes in the use of mobile dating applications in China

Mobile dating applications (MDAs), such as Momo and Tinder, allow mobile phone owners to meet potential mates through social media, thus contributing to the radicalization of Chinese attitudes toward sex. Although these applications may gratify the needs of users for love and sex, the potential of risk is often overlooked. However, it should be considered in their decision regarding whether to meet a stranger or not. This study investigated the motivations and risks involved in the use of MDAs to meet strangers and the outcomes of using this technology. The results showed that sexuality was the only predictor of the reasons that people use MDAs to meet people offline for dates and casual sex. Among the perceived risks of mobile dating, only the fear of self-exposure to friends, professional networks, and the community significantly explained why users would not meet people offline for casual sex.     

Does caloric restriction in the laboratory simply prevent overfeeding and return house mice to their natural level of food intake?

Some researchers have speculated that the senescence-retarding effect of caloric restriction on laboratory rodents is an artifact of overfeeding under captive conditions. The argument posits that mice in nature are chronically calorically restricted; therefore, the typical laboratory protocol of restricting animals to 60% of their ad lib food intake more realistically replicates life in the field: the conditions under which the animals' physiology has been designed by natural selection to thrive. The hypothesis concludes that instead of comparing control animals with restricted animals, we are in fact comparing overfed animals with adequately fed ones, and, not surprisingly, the overfed ones die younger. In this Perspective, the author discusses the merits and drawbacks of this hypothesis in light of energy consumption data for various types of mice.     

Urban change in the third world: are recent trends a useful pointer to the urban future?

"This paper has three aims. The first is to examine the reliability of the data base for the statistics which are used as the basis for commenting on urban change in 'the Third World'. The second is to explore whether valid generalisations about urban change can be made for the Third World. And the third is to examine the validity of United Nations projections for the Third World's urban future."
