Summary Sarawak is known as the “Land of Hornbills”, having the Rhinoceros Hornbill as the state emblem and with hornbills also being closely associated with important cultural symbols and beliefs among various local communities. However, up to date there is limited understanding on the perception, awareness, and beliefs of local communities towards hornbills. This paper aims to describe the aforementioned factors in western Sarawak, in hope of acquiring the socio-cultural information needed to fill the gap, and to clarify misconceptions towards hornbill conservation efforts in Sarawak. Data collection was accomplished using Open Data Kit (ODK). A total of 500 respondents were approached in five administrative divisions in western Sarawak, namely Kuching, Samarahan, Serian, Sri Aman, and Betong. The questionnaire was carefully formulated to control acquiescence bias that might arise. Boosted Regression Tree (BRT) modelling was conducted to evaluate the strongest demographic predictor variables influencing the answers and word clouds were used to visualise hornbill species by the local community. Sarawakians acknowledge the importance of hornbills as a cultural symbol (95%) despite hornbills being used for food, medicine, and decoration. Whilst this study describes the perceptions of hornbills in local communities, a comprehensive assessment throughout Sarawak is recommended for better understanding of hornbill importance in other communities. Such socio-cultural information is vital to ensure the success of conservation efforts and for effective management strategies of hornbills within Sarawak.

Understanding local community perceptions on impacts, causes, and responses to climate change is vital for promotion of community resilience towards climate change. This study explored local ecological knowledge (LEK) held by local communities on climate change trends and impacts in the Middle Zambezi Biosphere Reserve (MZBR), Zimbabwe. The objectives of the study were to (i) investigate local community perceptions on trends and causes of climate change, (ii) identify biophysical impacts of climate change at the local level, and (iii) explore the ecosystem-based adaptation strategies towards climate change. The study used a mixed methods approach where a household questionnaire survey (n=320), key informant interviews (n=12), and focus group discussions (n=8) were used to collect data between April 2015 and October 2016. Results from the study show that local communities have observed decreasing rainfall and increasing temperatures as key indicators of climate change. Local communities observed water scarcity, changes in vegetation phenology, livestock and wildlife mortalities, and food shortages due to drought as the major impacts on their livelihoods. LEK can contribute to adaptive management strategies that enhance resilience of socioecological systems (SES) in the face of climate change by providing information on the status and use of biophysical components of the environment and by highlighting potential local adaptation strategies that can sustain key livelihood practices.

The Relationship

The attitudes of local communities towards the development of dark tourism are still underexplored. This thorough analysis of the scientific knowledge available in renowned databases in the period from 2013 to 2019 aims at explaining the role of local communities in dark tourism, the advantages and disadvantages of its development, and the understanding of the conditions needed for its acceptance and support. The analysis has determined that every practice of dark tourism is conditioned by the context within which it was created, and that it has economic, socio-cultural and environmental advantages and disadvantages. The support of the local community for the development of dark tourism is crucial for its continuous existence, and it can depend on the management strategies and the benefits that dark tourism provides. The research results contribute to the corpus of literature, and may inform strategic guidelines for dark tourism management, as well as benefit the wider community through awareness of the necessity of prevention of tragic events. Further research on the topic should create management strategies of dark tourism that are acceptable to local communities.

With the unprecedented rate of biodiversity change in the world today, understanding how diversity gradients are maintained at mesoscales is a key challenge. Drawing on information provided by 3 comprehensive fishery surveys (conducted in different years but in the same season and with the same sampling design), we used boosted regression tree (BRT) models in order to relate spatial patterns of α-diversity in a demersal fish assemblage to environmental variables in the San Matias Gulf (Patagonia, Argentina). We found that, over a 4 yr period, persistent diversity gradients of species richness and probability of an interspecific encounter (PIE) were shaped by 3 main environmental gradients: bottom depth, connectivity with the open ocean, and proximity to a thermal front. The 2 main patterns we observed were: a monotonic increase in PIE with proximity to fronts, which had a stronger effect at greater depths; and an increase in PIE when closer to the open ocean (a ‘bay effect’ pattern). The originality of this work resides on the identification of high-resolution gradients in local, demersal assemblages driven by static and dynamic environmental gradients in a mesoscale seascape. The maintenance of environmental gradients, specifically those associated with shared resources and connectivity with an open system, may be key to understanding community stability.

Seminal Work

McIntyre, in his seminal work on Scottish franchise courts, argues that these courts were in decline in this period, and of little relevance to their local population. 1 But was that really the case? This paper explores that question, using a particularly rich set of local court records. By analysing the functions and significance of one particular court it assesses the role of this one court within its local area, and considers whether it really was in decline at this time, or if it continued to perform a vital role in its local community. The period studied is the mid to late seventeenth century, a period of considerable upheaval in Scottish life, that has attracted considerable attention from scholars, though often less on the experiences of local communities and people.

Node Problem

Complex networks analysis (CNA) has attracted so much attention in the last few years. An interesting task in CNA complex network analysis is community detection. In this paper, we focus on Local Community Detection, which is the problem of detecting the community of a given node of interest in the whole network. Moreover, we study the problem of finding local communities of high density, known as α-quasi-cliques in graph theory (for high values of α in the interval ]0,1[). Unfortunately, the higher α is, the smaller the communities become. This led to the maximal α-quasi-clique community of a given node problem, which is, the problem of finding local communities that are α-quasi-cliques of maximal size. This problem is NP-hard, then, to approach the optimal solution, some heuristics exist. When α is high (>0.5) the diameter of a maximal α-quasi-clique is at most 2. Based on this property, we propose an algorithm to calculate an upper bound to approach the optimal solution. We evaluate our method in real networks and conclude that, in most cases, the bound is very accurate. Furthermore, for a real small network, the optimal value is exactly achieved in more than 80% of cases.

Safety performance functions (SPFs) are essential tools to help agencies predict crashes and understand influential factors. Florida Department of Transportation (FDOT) has implemented a context classification system which classifies intersections into eight context categories rather than the three classifications used in the Highway Safety Manual (HSM). Using this system, regional SPFs could be developed for 32 intersection types (unsignalized and signalized 3-leg and 4-leg for each category) rather than the 10 HSM intersection types. In this paper, eight individual intersection group SPFs were developed for the C3R-Suburban Residential and C4-Urban General categories and compared with full SPFs for these categories. These comparisons illustrate the unique and regional insights that agencies can gain by developing these individual SPFs. Poisson, negative binomial, zero-inflated, and boosted regression tree models were developed for each studied group as appropriate, with the best model selected for each group based on model interpretability and five performance measures. Additionally, a linear regression model was built to predict minor roadway traffic volumes for intersections which were missing these volumes. The full C3R and C4 SPFs contained four and six significant variables, respectively, while the individual intersection group SPFs in these categories contained six and nine variables. Factors such as major median, intersection angle, and FDOT District 7 regional variable were absent from the full SPFs. By developing individual intersection group SPFs with regional factors, agencies can better understand the factors and regional differences which affect crashes in their jurisdictions and identify effective treatments.

AbstractWhile a large body of literature empirically documents an electoral advantage for local candidates, the exact mechanisms accounting for this effect remain less clear. We integrate theories on the political geography of candidate-voter relations with socio-psychological accounts of citizens’ local attachment, arguing that citizens vote for candidates from their own local communities as an expression of their place-based identity. To test our argument, we exploit a unique feature of the German mixed-member electoral system. We identify the causal effect of candidates’ localness by relying on within-electoral-district variation coupled with a geo-matching strategy on the level of municipalities ($$\hbox {N}=11175$$ N = 11175 ). The results show that voters exhibit a strong bias in favor of local candidates even when they are not competitive. More than only expecting particularistic benefits from representatives, citizens appear to vote for candidates from their own local community to express their place-based social identity.

Berberis lyceum Royle has such pronounced medicinal values that it is used as cure of many diseases and has exhibited great therapeutic effects among the local communities throughout the world. The present research was carried out to evaluate the quantitative ethnobotanical status and phytochemical analysis of B. lyceum. Regular field trips were arranged to the study area (Shangla District) in August 2017 to October 2019 and interviews with 100 residents (age range: 30 to 50 years) were conducted. The approach adopted for ethnobotanical data was semi-scientific as the inhabitants were not aware about the modern names of some diseases and therefore physician prescriptions were also consulted. Ethnobotanical data were examined using relative frequency of citation and % use value. The % use value of B. lyceum indicates that the people of District Shangla mostly used it for curing of different diseases. In spite of tremendous uses the plant still survived in this area mainly due to the non-accessibility for humans of the mountain tops; otherwise, increase in anthropogenic activities even in these hilly areas poses a threat of the eradication of this plant. To correlate the folkloric uses with its phytochemical composition, HPLC (high performance liquid chromatography) analysis was performed and a total of six phenolic compounds (quercetin, chlorogenic acid, berberine, rutin, mandellic acid, and hydroxy benzoic acid) were identified in its root. As most of the health complications are correlated to oxidative stress therefore in vitro antioxidant activity were also performed using DPPH (2, 2- diphenyl-1-picrylhydrazyl) and ABTS (2, 2′-azinobis-3-ethyl benzo thiazoline -6- sulfonic acid) assays. The observed antioxidant potential may most probably be due to berberine and chlorogenic acid that were present in highest concentration in the analyzed extract. The effectiveness of the selected plant as remedy for a number of diseases (that were pointed out by the local community) may be due to its phytochemical composition especially berberine and chlorogenic acid as oxidative stress is the root cause of many diseases. The plant extract exhibited high antioxidant potential (DPPH IC50 = 165µg/mL; ABTSIC50 = 110µg/mL) in relation to the detected concentration of berberine and chlorogenic acid. It can be inferred from experimental results that the ethnopharmacological efficacy of this endangered species may be due to its phytochemical composition and antioxidant activities. This case study helps to revive the importance of B. lyceum in local communities and emphasizes the need for its conservation.

Blue carbon ecosystem (BCE) initiatives in the Coral Triangle Region (CTR) are increasing due to their amplified recognition in mitigating global climate change. Although transdisciplinary approaches in the “blue carbon” discourse and collaborative actions are gaining momentum in the international and national arenas, more work is still needed at the local level. The study pursues how BCE initiatives permeate through the local communities in the Philippines and Indonesia, as part of CTR. Using perception surveys, the coastal residents from Busuanga, Philippines, and Karimunjawa, Indonesia were interviewed on their awareness, utilization, perceived threats, and management strategies for BCEs. Potential factors affecting residents’ perceptions were explored using multivariate regression and correlation analyses. Also, a comparative analysis was done to determine distinctions and commonalities in perceptions as influenced by site-specific scenarios. Results show that, despite respondents presenting relatively high awareness of BCE services, levels of utilization are low with 42.9–92.9% and 23.4–85.1% respondents in Busuanga and Karimunjawa, respectively, not directly utilizing BCE resources. Regression analysis showed that respondents’ occupation significantly influenced their utilization rate and observed opposite correlations in Busuanga (positive) and Karimunjawa (negative). Perceived threats are found to be driven by personal experiences—occurrence of natural disasters in Busuanga whereas discerned anthropogenic activities (i.e., land-use conversion) in Karimunjawa. Meanwhile, recognized management strategies are influenced by the strong presence of relevant agencies like non-government and people’s organizations in Busuanga and the local government in Karimunjawa. These results can be translated as useful metrics in contextualizing and/or enhancing BCE management plans specifically in strategizing advocacy campaigns and engagement of local stakeholders across the CTR.
