As ecological and environmental issues have received continuous attention, forest transition has gradually become the frontier and a hot issue, which have implications for biodiversity and ecosystem functioning. In this study, the spatial-temporal dynamics and the spatial determinants of forest quality were investigated using spatial econometric regression models at the province level, which contained 31 provinces, autonomous regions, and municipalities in China. The results showed that forest area, forest volume, forest coverage, and forest quality have greatly increased as of 2018, but uneven forest distribution is an important feature of forest adaptation to the environment. The global Moran’s I value was greater than 0.3, and forest quality of the province level had a positive spatial correlation and exhibited obvious spatial clustering characteristics. In particular, the spatial expansion of forest quality had shown an accelerated concentration. The most suitable model for empirical analysis and interpretation was the Spatial Durbin Model (SDM) with fixed effects. The average annual precipitation and the area ratio of the collective forest were positively correlated with forested quality (significance level 1%). Ultimately, this framework could guide future research, describe actual and potential changes in forest quality associated with forest transitions, and promote management plans that incorporate forest area changes.

Momentary Assessment

Most assessments of well-being have relied on retrospective accounts, measured by global evaluative well-being scales. Following the recent debates focused on the assessment of hedonic and eudaimonic well-being based on the elements of the PERMA theory, the current study aimed to shed further light onto the measurement of PERMA elements in daily life and their temporal dynamics. Through an Ecological Momentary Assessment (EMA) design (N=160), we examined the dynamics of change (e.g., baselines and intra-individual variability) in the PERMA elements using the mPERMA measure, which is an EMA-adapted version of the PERMA Profiler. Findings revealed that momentary experiences of well-being, quantified via PERMA elements, map onto their corresponding hedonic or eudaimonic well-being components, and its dynamical features provide novel insights into predicting global well-being. This work offers avenues for future research to assess well-being in real-time and real-world contexts in ecologically valid ways, while eliminating recall bias.

The Impact

Purpose The purpose of this paper is to contribute to the empirical literature of the macroeconomic effect of trade facilitation reforms by examining the impact of the latter on tax revenue in both developed and developing countries. The relevance of the topic lies on the fact that at the Bali Ministerial Conference of the World Trade Organization (WTO) in 2013, Trade Ministers agreed for the first time since the creation of the WTO (in 1995) on an Agreement to facilitate trade around the world, dubbed Trade Facilitation Agreement (TFA). The study considers both at-the-border and behind-the border measures of Trade Facilitation. Design/methodology/approach To conduct this study, the authors rely on the literature related to the structural factors that explain tax revenue mobilization. The authors mainly use within fixed effects estimator. The analysis relies on 102 countries (of which 23 industrial countries) over the period 2004-2007 (based on data availability). A focus has also been made on African countries, within the sample of developing countries. Findings The empirical analysis suggests evidence of a positive and significant effect of trade facilitation reforms on non-resources tax revenue, irrespective of the sample of countries considered in the analysis. Research limitations/implications This finding should contribute to dampening the fear of policymakers in developing countries, including Africa that the implementation of the TFA would entail higher costs, without necessarily being associated with higher benefits. An avenue for future research would be to extend the period of the study when data would be available. Originality/value To the best of the authors knowledge, this study had not been performed in the literature of the determinants of tax revenue mobilization, although fact-based analysis was performed.

Brand, von der Post, Ounsley, and Morgan (2019) introduced Bayesian posterior passing as an alternative to traditional meta-analyses. In this commentary I relate their procedure to traditional meta-analysis, showing that posterior passing is equivalent to fixed effects meta-analysis. To overcome the limitations of simple posterior passing, I introduce improved posterior passing methods to account for heterogeneity and publication bias. Additionally, practical limitations of posterior passing and the role that it can play in future research are discussed.

AbstractResearch on segregation is traditionally associated with studies on residential segregation and the patterns of spatial clustering of minority ethnic groups or residents with immigrant backgrounds. This chapter examines European research on spatial segregation through various social science disciplines, including urban studies, sociology, psychology, spatial and human geography. It presents the range of theoretical approaches employed to explain why people who belong, or are perceived to belong, to dissimilar social categories or to hold different identities become spatially separated from each other, and ways in which this may change. Factors that influence segregation are interrelated. A holistic, interdisciplinary approach to spatial segregation is, therefore, essential to understand such mechanisms and then design policies to counter any negative impacts of segregation. Individual and group experiences are shaped by varied contexts, whether residential, work, leisure, transport and daily encounters. This chapter examines approaches to spatial segregation from a variety of disciplinary perspectives and indicates possible directions for future research.

Abstract. The objective of this paper was to select a suitable data subset and statistical model for the estimation of genetic parameters for 36 traits of the linear type in 977 Old Kladruber horses. Two subsets were tested to identify a suitable subset for analysis. One subset included repeated evaluation of certain individuals, whereas the other did not. The most suitable subset included repeated evaluation (n=1 390). The selection of a suitable model was made from 4 candidate models. These models comprised a number of random effects (direct individual effect and animal permanent environmental effect of the animal) and a number of fixed effects (colour variant, stud, colour variant × stud interaction, sex, age at description, year of birth, year of description). The model was selected based on the Akaike information criterion (AIC, Akaike 1974), residual variance and heritability coefficient. The model that included colour variant, stud, colour variant × stud interaction, sex, age at description, and year of description as fixed effects and direct individual and animal permanent environment as random effects was the most suitable model for the estimation of genetic parameters and for the subsequent estimation of breeding values.

There is geographical variation in the ways in which people think, feel, and behave. How are we to understand the causes and consequences of such variation? Geographical psychology is an emerging subarea of research concerned with the spatial organization of psychological phenomena and how individual characteristics, social entities, and physical features of the environment contribute to their organization. Studies at multiple levels of analysis have indicated that social influence, ecological influence, and selective migration are key mechanisms that contribute to the spatial clustering of psychological characteristics. Investigations in multiple countries have shown that the psychological characteristics common in particular regions are respectively linked to important political, economic, and health indicators. Furthermore, results from large multilevel studies have shown that the psychological characteristics of individuals interact with features of the local environment to impact psychological development and well-being. Future research is needed to better understand the scale and impact of person-environment associations over time.

Creative Problem

Creative thinking is essential for the progress in education, industry and life in general. Incubation is a widely studied phenomenon in creativity research, referring to leaving a problem aside for a period, to accrue performance on a creative problem. This study investigated the effect of incubation on creative problem-solving by means of a pretest-posttest quasi-experimental design, and remote associates tasks (RATs) were used as a measure of creative problem-solving. For this purpose, a sample of 60 students (22 males, 38 females) was recruited from the population of a private university. They were assigned to a control condition and two different experimental conditions based on the time of onset of incubation. The data collected was analyzed for a significant effect across all conditions by means of a chi-squared test and covariates were inferred by means of Spearman's Rho, with a significance level set at ?<.05. The results did not find an incubation effect in creative problem-solving, and several possible explanations may account for this trend, especially the limited cross-cultural application of measurement tools and theoretical paradigms. The disparity is especially prominent with regards to Pakistan, which is predominantly collectivistic, and the educational system stymies creative thinking. Future research must take into account the relevance of culture in creative problem-solving, and propose solutions to circumvent the dearth of creative potential in developing nations such as Pakistan.

Purpose Board faultlines, which reflect intrinsic divisions of board members into relatively homogeneous subgroups, are associated with poor firm performance. This paper aims to extend the existing board faultline research by examining how acquisition deal size moderates the negative implications of board faultlines. Design/methodology/approach This paper uses a sample of acquisitions and a quantitative research approach to conduct statistical analysis. Findings Using a sample of acquisitions announced between 2007 and 2016, this paper finds evidence suggesting that strong faultlines are associated with poorer acquisition outcomes in the long-term, but not in the short term. Further, this paper finds that the effect of faultline strength on long-term acquisition outcomes is weaker for larger acquisition deals than smaller acquisition deals. The findings are consistent with deal size moderating the relation between faultlines and acquisition outcomes. Research limitations/implications This paper addresses possible endogeneity through firm fixed effects and instrumental variable analysis. Although this paper provides evidence on the moderating role of deal size in the context of faultlines, future research could examine the role of additional moderators, such as pro-diversity, trust, board leadership and board and task characteristics. Practical implications The findings suggest that boards need to be aware of situations where the negative effects of faultlines are more likely to come to the fore. For example, faultlines are more likely to play a role in more routine, obscure monitoring than for high-profile strategic decisions. Originality/value The study is multidisciplinary as it draws on the management, organizational behaviour and psychology and finance literature. It contributes to the developing literature on faultlines in several important ways. First, this paper supports their view that faultlines have adverse effects on board performance by showing that faultlines negatively impact discrete strategic investment decisions. Second, this paper provides evidence that deals size moderates the faultline-acquisition performance relation, indicating that the role of faultlines is contextual. Third, this paper finds evidence that suggests investors do not factor in board faultlines when responding to acquisition announcements.

Abstract This paper applies bootstrap methods to LM tests (including LM-lag test and LM-error test) for spatial dependence in panel data models with fixed effects, and removes fixed effects based on orthogonal transformation method proposed by Lee and Yu (2010). The consistencies of LM tests and their bootstrap versions are proved, and then some asymptotic refinements of bootstrap LM tests are obtained. It shows that the convergence rate of bootstrap LM tests is O((NT)−2) and that of fast double bootstrap LM tests is O((NT)−5/2). Extensive Monte Carlo experiments suggest that, compared to aysmptotic LM tests, the size of bootstrap LM tests gets closer to the nominal level of signifiance, and the power of bootstrap LM tests is higher, especially in the cases with small spatial correlation. Moreover, when the error is not normal or with heteroskedastic, asymptotic LM tests suffer from severe size distortion, but the size of bootstrap LM tests is close to the nominal significance level. Bootstrap LM tests are superior to aysmptotic LM tests in terms of size and power.

The Impact

In the implementation of decentralization, the Special Allocation Fund (DAK) for health is given to certain areas of Indonesia to support health financing. The performance of this financing, along with national health development priorities’ achievements, is illustrated through the indicators of coverage of deliveries in health care facilities (PF) and coverage of first neonatal visits (KN1). Yearly increases in the health DAK budget have not been accompanied by increases in these coverages, and there are still significant disparities between regions. Using secondary data at the district/city level for 2014–2017, this study aims to investigate the impact of health DAK on coverage of PF and KN1. The analytical method deployed is linear regression of panel data using a fixed-effects model. The results show that in the short term, health DAK has a positive but insignificant effect on PF and KN1 coverage. However, health DAK has a positive and significant impact on PF coverage in the second year. Impact on KN1 coverage is unfeasible, even over a period of two years. These results indicate that the processes of planning, budgeting, and administering of health DAK require improvement so that benefits can be felt in the short term through better innovations in health programs. Nevertheless, given that our findings are based on a short period of study, the results from such analyses should consequently be treated with the utmost caution Therefore, future research should target a longer period of data collection to detect more trusty lagged effects and structural breaks of a policy intervention.
