Climate changes are a phenomenon that can affect the daily activities of rural communities, with particular emphasis on those directly dependent on the agricultural and forestry sectors. In this way, the present work intends to analyse the impact that climate changes have on forest risk assessment, namely on how the occurrence of rural fires are affecting the management of the forest areas and how the occurrence of these fires has evolved in the near past. Thus, a comparative analysis of the data provided by IPMA (Portuguese Institute of the Sea and the Atmosphere), was carried out for the period from 2001 to 2017 with the climatic normal for the period between 1971 to 2000, for the variables of the average air temperature, and for the precipitation. In this comparative study, the average monthly values were considered and the months in which anomalies occurred were determined. Anomalies were considered in the months in which the average air temperature varied by 1 °C than the value corresponding to the climatic norm, in at least 50% of the national territory. The same procedure was repeated for the variable precipitation, counting as anomaly the occurrence of a variation in precipitation of 50%, also in 50% of the national territory. Then the calculation of the moving averages for cycles of 3, 5 and 7 periods were applied, and the trend lines were projected. Subsequently, the relationship between the results obtained and the occurrence of rural fires as well as the spatial distribution of forest area, species and structure were analyzed. From the results obtained it was possible to confirm the existence of a tendency for the occurrence of climatic anomalies, highlighting the occurrence of an increasing number of months with temperatures higher by at least 1 °C. It was possible to foresee the relation between the occurrence of rural fires and the periods of anomaly and absence of precipitation. From the results obtained it is also possible to infer that, analyzing the tendency for these phenomena to occur, it can be necessary to change the “critical period of rural fires”, since it is verified that what is currently in use does not covers the entire period where anomalies occur and where large-scale rural fires potentially can happen.

Abstract. With global climate changes intensifying, the hydrological response to climate changes has attracted more attention. It is beneficial not only for hydrology and ecology but also for water resource planning and management to understand the impact of climate change on runoff. In addition, there are large spatial variations in climate type and geographic characteristics across China. To gain a better understanding of the spatial variation of the response of runoff to changes in climatic factors and to detect the dominant climatic factors driving changes in annual runoff, we chose the climate elasticity method proposed by Yang and Yang (2011). It is shown that, in most catchments of China, increasing air temperature and relative humidity have negative impacts on runoff, while declining net radiation and wind speed have positive impacts on runoff, which slow the overall decline in runoff. The dominant climatic factors driving annual runoff are precipitation in most parts of China, net radiation mainly in some catchments of southern China, air temperature and wind speed mainly in some catchments in northern China.

Islam as a religion wants its people to always maintain a balance between religiosity (al din) and worldly problems (al dunya). The relationship between the two describes something that is separate but inseparable (harmony). However, for modern society, this condition often creates contradictions, this condition was seen at the time of the Covid 19 pandemic. The implementation of Large-Scale Social Restrictions by the government in an effort to overcome the spread of the impact of Covid 19 to the community by limiting activities in mosques and allowing activities in the market to continue in fact responded by the community differently. The methodology used is qualitative by using social policy analysis. This paper tries to examine social policies towards the application of large-scale social restrictions on mosques and markets. In this paper, the sociology of law theory is used, namely Law is a social engineering tool which emphasizes that law becomes the commander who must bring change to society. The results obtained in the research are that the community responds to the large-scale social restriction policy differently, where the purpose of the policy is for the community to be expected to make changes by complying with the rules that have been set by the government, the conditions for rejection and various responses are caused by disharmony between implementation of policies with public awareness of the law.Keyword : Policy, large-Scale Restrictions and the sociology of law. AbstrakIslam sebagai agama mengkhendaki umatnya agar senantiasa menjaga keseimbangan antara religiusitas (al din) dan masalah keduniaan (al dunia). Hubungan keduanya menggambarkan sesuatu yang terpisah namun tidak bisa dipisahkan (harmoni). Namun bagi masyarakat modern kondisi tersebut seringkali justru menimbulkan pertentangan, kondisi tersebut nampak pada saat terjadinya pandemi Covid 19. Penerapan Pembatasan Sosial Berskala Besar oleh pemerintah dalam upaya penanggulangan penyebaran dampak Covid 19 kepada masyarakat dengan membatasi aktivitas di masjid dan membiarkan kegiatan di pasar tetap berjalan nyatanya direspon oleh masyarakat secara berbeda. Metodologi yang digunakan adalah kualitatif dengan menggunakan analisis kebijakan sosial, Tulisan ini mencoba menelaah kebijakan sosial terhadap penerapan pembatasan sosial berskala besar terhadap masjid dan pasar. Dalam penulisan ini dipergunakan teori sosiologi hukum yaitu Law is a tool social engineering yang menegaskan bahwa hukum menjadi panglima yang harus membawa perubahan terhadap masyarakat. Hasil yang diperoleh dalam penelitian adalah Masyarakat merespon kebijakan pembatasan sosial berskala besar tersebut secara berbeda, dimana tujuan kebijakan tersebut adalah untuk masyarakat diharapkan dapat melakukan perubahan dengan mematuhi aturan yang telah di tetapkan oleh pemerintah, kondisi penolakan dan respon beragam tersebut di sebabkan oleh ketidak harmonisannya antara penerapan kebijakan dengan kesadaran masyarakat terhadap hukum.Kata Kunci : Kebijakan,  Pembatasan Sosial Berskala Besar dan Sosiologi Hukum

Unbiased science dissemination has the potential to alleviate some of the known gender disparities in academia by exposing female scholars’ work to other scientists and the public. And yet, we lack comprehensive understanding of the relationship between gender and science dissemination online. Our large-scale analyses, encompassing half a million scholars, revealed that female scholars’ work is mentioned less frequently than male scholars’ work in all research areas. When exploring the characteristics associated with online success, we found that the impact of prior work, social capital, and gendered tie formation in coauthorship networks are linked with online success for men, but not for women—even in the areas with the highest female representation. These results suggest that while men’s scientific impact and collaboration networks are associated with higher visibility online, there are no universally identifiable facets associated with success for women. Our comprehensive empirical evidence indicates that the gender gap in online science dissemination is coupled with a lack of understanding the characteristics that are linked with female scholars’ success, which might hinder efforts to close the gender gap in visibility.

Purpose For most manufacturing firms, technological innovations are usually the key strategies to gain their competitive advantages. However, competing strategically through service provision is becoming an important strategy for most industries. A growing demand for packaged product and service delivery is blurring the traditional boundaries between manufacturing and service firms. This trend is called “servitization.” Prior research had different perspectives on the relationship between technological innovations and servitization. Some argued that as servitization exerts the innovative convergence of products and services, the possession of appropriate readiness and absorption capacity through technological innovations for a manufacturing firm is critical to the success of servitization. In contrast, some argued that the knowledge gained from developing technological innovations cannot be applied to the creation of services due to the fundamental difference between technology and service. These contradicting arguments motivated the authors to study the relationship between technological innovations and servitization a step further. The paper aims to discuss these issues. Design/methodology/approach To address the research gap, the authors conducted an empirical study based on the large-scale samples from the second Taiwan Community Innovation Survey (Taiwan CIS). A multivariate logistic regression model was applied in the research. Findings The authors found that different types of technological innovations, namely product innovation and process innovation, have different impacts on servitization. The innovativeness level of the technological innovation moderates the relationship between technological innovation and servitization. Based on the above findings, this research specifically explains the causes of the contradictory results of the prior research. Originality/value The values of this research are twofold. Its academic contribution rests on bridging the literature of innovation and servitization, and on providing a model to clarify the relationships among technological innovation type, level of innovativeness and servitization. Its practical contribution lies in its establishment of a guideline that illuminates manufacturing firms reinforcing service delivery through their existing technological innovation trajectory.

Abstract In the digital age, space has become increasingly structured by the circuitry of global capital, communications and commodities. This ‘network society’ splinters and fragments territorial space according to the hidden logic of networked global capital; with successful criminal entrepreneurs connecting bases in low-risk, controllable territories with high-profit markets. Drawing on a recent, large-scale study of organised crime in Scotland, in this paper we elaborate the relationship between place, territory and criminal markets in two contrasting communities. The first is an urban neighbourhood with a longstanding organised crime footprint, where recognised local criminal groups have established deep roots. The second is a rural community with a negligible organised crime footprint, where the drug economy is serviced by a mobile criminal network based in England. Through comparison of the historical roots and contemporary routes of these criminal markets, we note both similarity and difference. While both communities demonstrated evidence of ‘networked territorialism’, key differences related to historical and social antecedents, in particular the impact of deindustrialisation.

The UK is restructuring the fiscal policy framework once again, with an intention to move toward independent assessment and forecasting in the budget process. At the same time a large-scale, if delayed, fiscal consolidation is planned at a time when there is significant spare capacity in the economy. Economic growth is also projected to be below trend, at least this year and perhaps next. It is unusual to see a fiscal tightening when the output gap appears to be widening. These policy settings should be seen in the context of the most radical change in the nature of the relationship between the government and the economy for at least thirty years. This note assesses the impact of the new programme on the economy as well as setting out a projection for the medium-term public finances.

Human lateral preferences, such as handedness and footedness, have interested researchers for decades due to their pronounced asymmetries at population level. While there are good estimates on the prevalence of handedness in the population, there is, to this, day no large-scale estimation on the prevalence of footedness. Furthermore, the relationship between footedness and handedness still remains elusive. Here, we conducted meta-analyses with four different classification systems for footedness on 145,150 individuals across 164 studies including new data from the ALSPAC cohort. The aims of the study were to determine a reliable point estimate of footedness, to study the association between footedness and handedness, and to investigate moderating factors influencing footedness. We showed that the prevalence of atypical footedness ranges between 12.10% using the most conservative criterion of left-footedness to 23.7% including all left- and mixed-footers as a single non-right category. As many as 60.1% of left-handers were left-footed whereas only 3.2% of right-handers were left-footed. Males were 4.1% more often non-right-footed compared to females. Individuals with psychiatric and neurodevelopmental disorders exhibited a higher prevalence of non-right-footedness. Furthermore, the presence of mixed-footedness was higher in children compared to adults as well as in experienced athletes compared to the general population. Finally, we showed that footedness is only marginally influenced by cultural and social factors, which have been shown to play a crucial role in the determination of handedness. Overall, this study provides new and useful reference data for laterality research. Furthermore, the data suggest that footedness is a valuable phenotype for the study of lateral motor biases, its underlying genetics and neurodevelopment.

To determine the impact of influencing factors on unsupported roof stability in coal mine roadway, a mechanical model of the unsupported roof was built. FLAC 3D numerical simulation was utilized to study the stability of the unsupported roof under the influence of the depth of the roadway, the thickness of the roof, and the unsupported-support distance. In view of the key influencing factors, the geological conditions of the site, and the relationship between the tensile stress and tensile strength of the unsupported roof, the maximum unsupported roof distance during roadway excavation was determined. Considering the surplus safety factor of the unsupported roof, the reasonable unsupported roof distance during the excavation of roadway 150802 was finally determined to be 2.08 m. The comprehensive roadway excavation speed increased by 62.7%, achieving a monthly progress over 500 m.
