Trawl impacts on the relative status of biotic communities of seabed sedimentary habitats in 24 regions worldwide

Bottom trawling is widespread globally and impacts seabed habitats. However, risks from trawling remain unquantified at large scales in most regions. We address these issues by synthesizing evidence on the impacts of different trawl-gear types, seabed recovery rates, and spatial distributions of trawling intensity in a quantitative indicator of biotic status (relative amount of pretrawling biota) for sedimentary habitats, where most bottom-trawling occurs, in 24 regions worldwide. Regional average status relative to an untrawled state (=1) was high (>0.9) in 15 regions, but <0.7 in three (European) regions and only 0.25 in the Adriatic Sea. Across all regions, 66% of seabed area was not trawled (status = 1), 1.5% was depleted (status = 0), and 93% had status > 0.8. These assessments are first order, based on parameters estimated with uncertainty from meta-analyses; we recommend regional analyses to refine parameters for local specificity. Nevertheless, our results are sufficiently robust to highlight regions needing more effective management to reduce exploitation and improve stock sustainability and seabed environmental status—while also showing seabed status was high (>0.95) in regions where catches of trawled fish stocks meet accepted benchmarks for sustainable exploitation, demonstrating that environmental benefits accrue from effective fisheries management. Furthermore, regional seabed status was related to the proportional area swept by trawling, enabling preliminary predictions of regional status when only the total amount of trawling is known. This research advances seascape-scale understanding of trawl impacts in regions around the world, enables quantitative assessment of sustainability risks, and facilitates implementation of an ecosystem approach to trawl fisheries management globally.

Measuring Social Mobility in Historic and Less Developed Societies

In societies where surnames are inherited from parents, we can use these names to estimate rates of intergenerational mobility. This chapter explains how to make such estimates, and illustrates their use in pre-industrial England and modern Chile and India. These surname estimates have the advantage that they require much less data than traditional parent–child estimates. They are also more robust to errors in status data. Thus, they can be used to estimate social mobility rates in early societies such as England 1300–1800, or in less developed societies now. Surnames measure a different aspect of social mobility than conventional measures, but this surname measure is the one that matters when we consider group-level convergence of social status, or the time needed for any disadvantaged groups to attain at least average status measured in generations. Surnames thus allow us to measure a key element in the multigenerational mobility process.

The Effect of Far-Infrared Therapy on the Peritoneal Membrane Transport Characteristics of Uremic Patients Undergoing Peritoneal Dialysis: An Open-Prospective Proof-of-Concept Study

Long-term peritoneal dialysis (PD) can lead to detrimental changes in peritoneal membrane function, which may be related to the accumulation of glucose degradation products. A previous study demonstrated that 6 months of far-infrared (FIR) therapy may decrease glucose degradation products in PD dialysate. Due to limited literature on this matter, this study aims to investigate the effect of FIR therapy on the peritoneal membrane transport characteristics of PD patients. Patients were grouped according to baseline peritoneal transport status: lower transporters (low and low-average) and higher transporters (high-average and high). Both groups underwent 40 min of FIR therapy twice daily for 1 year. In lower transporters, FIR therapy increased weekly dialysate creatinine clearance (6.91 L/wk/1.73 m2; p = 0.04) and D/P creatinine (0.05; p = 0.01). In higher transporters, FIR therapy decreased D/P creatinine (−0.05; p = 0.01) and increased D/D0 glucose (0.05; p = 0.006). Fifty percent of high transporter patients shifted to high-average status after FIR therapy. FIR therapy may decrease D/P creatinine for patients in the higher transporter group and cause high transporters to shift to high-average status, which suggests the potential of FIR therapy in improving peritoneal membrane function in PD patients.

A Chronic Lack of Perceived Low Personal Control Increases Women and Men’s Self-Reported Preference for High-Status Characteristics When Selecting Romantic Partners in Simulated Dating Situations

The question what people desire in their romantic partner has hitherto been dominated by a focus on gender. It has been repeatedly found that, when asked what they find important in selecting a partner, women indicate that they find status more important compared to men. Across five studies, we move beyond gender and base ourselves on general theories of control deprivation to test the effect of differences in perceived personal control on stated partner preferences. We find that low-control people—both women and men—value characteristics associated with status more in romantic partners at the expense of other desirable traits (Study 1a and 1b). Furthermore, in simulated dating settings, low-control people make corresponding dating choices and prefer hypothetical high-status partners over low- (Study 2a) or average-status partners (Study 2b). Our final study suggests a beneficial aspect: Thoughts of dating a high-status partner can repair low-control people’s feelings of control (Study 3).

Social Economic Status of Etawa (Pe) Goats Farmers in Tamansari Village, Ampelgading District, Malang Regency, Indonesia

This research was conducted in October 2019 at Tamansari Village, Ampelgading District, Malang Regency. This study aims to describe (1) household characteristics of PE goat farmers in Tamansari Village, Ampelgading District, Malang Regency, (2) ownership status of production facilities assets, (3) ownership characteristics of PE goats include ownership status, rearing purposes, average number of ownership, the average number of sales and sales value of PE goats. This study uses a survey method. The type of data taken is primary data through interviews. The data obtained were then analyzed descriptively. The results showed that the respondents were at productive age, had a relatively low level of formal education, had a small number of family members, and were very experienced in PE goats breeding. The assets of production facilities that owned by goat farmers are barns, feed warehouses, wheelbarrows, motorcycles and handphones. The average status of livestock ownership is self-owned with the aim of raising PE goats as the main business and side business. The average ownership of PE goats in Tamansari Village was started from 14.50 ± 3.90 in Tamansari sub-village to 17.57 ± 11.30 in Tamanrejo sub-village. The average livestock sales per year was started from 5.82 ± 6.01 heads in Tamansari sub-village to 9.14 ± 9.82 heads in Tamanrejo sub-village. The average value of livestock sales received by breeders were started from IDR 1.79 ± 0.69 million per head in Tamansari sub-village to IDR 1.90 ± 1.23 million per head in Tamanrejo sub-village.

Sampling through time

Many ecological research and resource monitoring programs must deliver good estimates of both current resource status and long-term trend. The simple two-occasion context frames the trade-offs in design of surveys to achieve these objectives. If the objective is to estimate change in status (trend), then most precise estimation is achieved by full retention of a random sample selected at time 1. If the objective is to estimate average status, then most precise estimation is achieved by selecting independent random samples. If a survey has both objectives, then a compromise design, involving partial retention and partial replacement of the initial sample, is optimal (i.e., will have intermediate performance for status and trend). Sampling designs for long-term monitoring (and before/after assessment monitoring) have two distinct components: a membership design which specifies selection of groups of units to be designated as sample panels, and a revisit design that specifies when these panels of units should be visited (revisited). For example, some randomly selected panels might be visited in years one to three, then dropped out of rotation for three years and then revisited in years–seven to nine, and so on. One panel might be revisited every year, and other panels might be visited only a single time. Design-based estimates of measures of status and trend are derived for some simple membership and revisit designs. The theory of dual frame sampling is applied to estimation of the number of active bald eagle nests on a wildlife refuge.

The Luck of the Draw: How Attributions for Poverty Shape Support for Economic Inequality

Despite growing economic inequality the American population remains relatively un-motivatedto tackle this issue–why? In six studies (n = 34,198), I aimed to answer this question byexploring the link between both dispositional and situational attributions for poverty andsupport for economic inequality. In Study 1 I used cross-national data from 34 countriesto examine the relationship between attributions for poverty and support for economic inequality.I found that people demonstrated less support for economic inequality in countrieswhere the majority of respondents provided situational (as opposed to dispositional) attributionsfor poverty. In Study 2a I had participants complete an immersive online povertysimulation or play Monopoly. I found that relative to Monopoly, the poverty simulationled to an increase in situational attributions for poverty and turn diminished support foreconomic inequality and increased support for redistribution. In Study 2b I conducted ahigh-powered pre-registered replication and extension of these results. In Study 3a, I presentedparticipants with evidence counter to the stereotype that the poor are lazy by havingthem interact with a low-status (versus average-status) status confederate. I found that thecross-status interaction led to a decrease in dispositional attributions for poverty which inturn decreased support for economic inequality. In Study 3b I conducted a high-poweredpre-registered replication which strengthened the design of the previous study and largelyreplicated these results. Lastly, in Study 4, in order to determine the specificity of relationshipbetween causal attributions and support for economic inequality I conducted a fieldquasi-experiment in undergraduates enrolled in various introductory psychology classes. Icompared attributions for poverty and support for economic inequality over the course of asemester in students who were taking a class that explicitly highlights the situational causesof behaviour versus a series of classes without this explicit framing. I found that taking acourse centred around demonstrating the impact situational factors have in influencing behaviourdid not shift support for economic inequality relative to students in various controlclasses. Overall, this dissertation presents the first experiments showing how attributions forpoverty can shape broader economic attitudes, such as support for economic inequality andhow various simple and low-cost interventions can be leveraged to promote greater socialequality.

The psychosocial development of High-Status, Average Status and Low-Status Servicemen for a Fixed Period

The article presents the results and their interpretation analysis of a research of interrelationship between status-role position of the individual in the informal intergruppo structure of closed communities and the peculiarities of his psychosocial development (as an example, army units, brought up by servicemen for a fixed period). The study was elaborated and implemented on the basis of the theory of psychosocial development. The empirical base of the study consists of high secret army units, i.e. real closed communities. In total 13 such kind of groups took part in the research. The integral status of group members in the structure of interpersonal relations was calculated in each of them, according to the results of sociometry, referencemetrical procedures and methodical technique of identifying the informal intergruppo structure of power in a contact community, being used the algorithm by Kondratiev M.Y. The peculiarities of psychosocial identity of the subjects were revealed simultaneously with using the technique of “differential of psychosocial development”. On the bases of the obtained data analysis it was shown that the level of psychosocial development of higher status members in closed communities is essentially lower than of average status and low-status ones. The detailed explanatory scheme of this phenomenology was presented, being used psychosocial development theory as the basic interpretive key.

Relevance status value model of Index Islamicus on Islamic History and Civilizations

Purpose – The purposes of this study were to measure the relevance status of Index Islamicus, evaluate the semantic correlation between a query and documents and inquire the basis of its rank. Sorting the retrieved results from the most relevant to the least relevant is the common option of an information retrieval system. This sorting mechanism or relevance judgment is computed by measuring closeness of query with its documents. Design/methodology/approach – Forming up 100 queries on Islamic History and Civilizations, with two indexing elements (keyword and concept), a laboratory experiment was generated on its first ten items of the rank. Throughout an experimental research design, the relevance status value formula was used to measure system-computed rank and compare it with mean average precision. Findings – The results showed that the average status value of Index Islamicus’s ranking on relevance criterion was 18 per cent effective in terms of retrieving precise documents. Despite the main focus of this study being only on one subject domain and the items calculated were only 1,000, this small percentage of its ranking mechanism proved that semantic correlations between queries with subject domain did not achieve the satisfactory level. Research limitations/implications – Implication of this study could be a guideline for further research on ranking mechanism of other search engines because the limitation of this study was Index Islamicus being the only database, which was the focus of this study. Practical implications – Throughout this study, Index Islamicus would be benefited knowing the status of its ranking mechanism as well as other databases can make further research on their own ranking method following this study. Social implications – Researchers and vendors of online databases can ensure their users a true platform of search engine with a proper ranking list. Originality/value – Relevance status value model for Index Islamicus on Islamic History and Civilization that allows the system to rank documents according to the match between document and query and gives the idea of a better index. The model improves the system’s ranking mechanism, and promotes the use of semantic relationships. This research promotes the computation of relevance status value by domain for capturing subject-specific relevance criteria and semantic relationships.
